Description
Technical Field
The invention relates to structural configuration of a plate oven, in particular to an oven door adjusting method and an oven door adjusting device of the plate oven.
Background
In general, a process for producing a printed circuit board or a carrier board (hereinafter referred to as a board) includes steps of ink coating, drying, baking, and the like. Wherein, the baking process of the plate is mostly carried out in a tunnel oven or an oven with independent batch space.
The tunnel oven is provided with at least two passage openings for loading and discharging the plate, and a plate passage is arranged between the two passage openings to be communicated. In the more advanced tunnel oven, a plurality of temperature control cabins for standing, baking, cooling and the like are formed between the loading and discharging passage openings of the plate, and passage openings for communicating the plate passages are also formed between the temperature control cabins. The plate waiting for baking in the tunnel oven can be in a piece-by-piece stepping transfer mode or a batch stepping transfer mode of a plurality of pieces, enters the plate channel from the channel port of the loading plate, sequentially passes through the channel ports of the temperature control cabins, and then is moved out of the oven through the channel port of the discharging plate. In addition, ovens having separate batch spaces typically have only a single port in the interior of the oven that is externally accessible for both loading and unloading of the panels.
Further, the above-described types of ovens typically rely on a drive member to carry the plate members into and out of the oven through the port. When the plate is in a sheet-by-sheet stepping transfer mode, the transmission element can be a chain capable of moving in a loop, a plurality of clamps are arranged on the chain at intervals, the plate is clamped by the clamps, so that the plate can enter the plate channel through the channel opening in a hanging mode and move out of the oven. When the plate adopts a batch stepping transfer mode, the transmission element can be a plurality of walking beams capable of generating interactive motion for carrying the plate in a reciprocating stepping way, besides, the transmission element for carrying the plate into and out of the oven can also be a pushing, pulling or other equivalent mechanisms capable of driving the plate to move in the plate channel besides the chains and the beams.
In addition, a heater (such as an electrothermal tube) is arranged in the oven, and heat energy can be generated by the heater to adjust and control the temperature in the oven or a part of the temperature control cabin of the oven to reach the expected heating temperature, so as to bake and dry the plate. Because the oven is communicated with the outside through the passage openings of the loading and discharging plate, and the plate passages are communicated with each other through the passage openings among the temperature control cabins for the oven with a plurality of temperature control cabins, in general, heat energy generated by the heater can flow outwards through the passage openings or overflow heat energy through the passage openings of the temperature control cabins to the adjacent temperature control cabins, the effect of standing, baking or drying the plate in the oven or the temperature control cabins thereof is affected, and the problem of electric energy consumption of the heater is even increased.
To overcome this problem, in the prior art ovens, a movable door has been provided at the port, which door is normally fully closed, and is fully opened when a panel is to be introduced into or removed from the panel through the port, or when a panel is to be introduced from one temperature-controlled compartment into another, and is fully closed again after the panel has passed through the port, thus effectively reducing heat loss in the oven, particularly in each temperature-controlled compartment.
Moreover, according to the prior art, the time that the plate members need to stay at intervals in the transferring process is relatively longer than that of the plate members which are carried stepwise in a piece-by-piece manner, so that the movable furnace door is suitable for being installed in an oven for carrying the plate members stepwise in a batch manner, and ideal energy-saving benefit can be obtained.
However, for the oven for carrying the plate in steps by pieces, since the time for the plate to stay at intervals of the step-by-step carrying by pieces is relatively short, the movable oven door is arranged at the passage opening without affecting the moving efficiency of the step-by-step carrying plate, so as to control the passage opening to be fully opened or fully closed, which has no substantial benefit, and even can not overcome the problems of heat energy loss and electric energy loss.
Furthermore, since the panel has a variety of different dimensions, a single oven must be able to receive panels of different dimensions for baking and drying. However, when the movable furnace door is completely opened and the area of the plate is relatively smaller than the passage opening, a considerable open area exists between the peripheral end edge of the plate and the passage opening, so that heat energy in the oven or each temperature control cabin is forced to be dissipated outwards through the open area, and the problems of heat energy loss and electric energy loss are also caused.
Therefore, no matter the plate is transferred in a step-by-step or batch manner, the movable furnace door installed in the conventional oven can not reduce the outward loss of heat energy in the oven through the passage opening without preventing the plate from passing through the passage opening, so that the movable furnace door has become a technical problem to be improved.

Detailed Description
The invention is specifically exemplified by a continuous oven illustrating the details of its implementation. For this reason, please refer to fig. 1a, the method for adjusting the oven door of the plate oven according to the present invention includes the following steps S1 to S4:
step S1, planning a plate channel according to the plate area
Referring to fig. 2 and 3 in combination, the plate 30 has four end edges, including a quadrangular area surrounded by a top end edge 30a, two side end edges 30b and 30c, and a bottom end edge 30d, wherein the top end edge 30a and the bottom end edge 30d are opposite sides, and the two side end edges 30b and 30c are opposite sides. A plate channel 11 is provided in the oven 10 for moving the plate 30, the plate channel 11 having at least one quadrangular channel opening 12, the plate 30 being displaceable in the plate channel 11 via the channel opening 12. The number of ports 12 may vary depending on the configuration of the oven 10, for example, a tunnel oven 10 having two ports 12 for loading and unloading the plate 30, an oven 10 having independent batch spaces in which the plate ports 11 are normally only in communication with a single port 12, and an oven 10 having a plurality of heating compartments in which the plurality of heating compartments are in communication via ports 12, that is, the number of ports 12 is plural.
Step S2, configuring a transmission element
The passage opening 12 has four sides (top side 12a, double sides 12b, 12c, bottom side 12 d), wherein the top side 12a and the bottom side 12d are opposite sides and the double sides 12b, 12c are opposite sides. The top rim 12a is provided with a driving member 40 for carrying the plate 30 into and out of the oven 10, the driving member 40 may be a chain which can move around in this embodiment, a plurality of plate frames for holding the plate 30 are arranged on the chain at intervals, and a clamp is arranged on the plate frames so as to carry the plate 30 into and out of the oven in a hanging manner step by step. Alternatively, the drive member 40 may be a bridge (walkingbeam, not shown) that is capable of reciprocal movement for carrying the plate members 30 in batches in steps in a hanging fashion into and out of the oven.
Further, when the driving element 40 is used to step the plate 30 into and out of the oven in a hanging manner, the top frame 12a of the driving element 40 may be disposed at the top of the passage opening 12, and the plate 30 is hung by the driving element 40 and enters and exits the oven 10 through the passage opening 12. In this embodiment, the plate 30 receives the hanging of the transmission element 40 via its top end edge 30a, that is, the top end edge 30a of the plate 30 corresponds to the top frame edge 12a of the passage opening 12, the two side end edges 30b, 30c of the plate 30 correspond to the two side frame edges 12b, 12c of the passage opening 12, respectively, and the bottom end edge 30d of the plate 30 corresponds to the bottom frame edge 12d of the passage opening 12. In addition, when the driving element 40 is a pushing mechanism, a pulling mechanism, or other equivalent mechanism capable of producing linear movement, the driving element 40 may be disposed at any one of the three sides (i.e. the two sides 12b, 12c and the bottom side 12 d) except the top side 12a of the passage opening 12.
Step S3, configuring a movable door plate
In the embodiments shown in fig. 2 to 8, only three movable door panels are illustrated, but the number of door panels of the present invention is not limited thereto, and in essence, the number of door panels of the present invention may be at least two (described in detail below).
As shown in fig. 3, when the transmission element 40 is disposed on the top frame 12a of the top of the passage opening 12, one movable door panel 20 can be further disposed on each of the remaining three frames (i.e., the two side frames 12b, 12c and the bottom frame 12 d) of the passage opening 12, so that the number of door panels is three. The door panels 20 disposed on the double side frames 12b and 12c may be moved along the same coordinate axis, which is practically the coordinate horizontal line 14. The door panel 20 disposed on the bottom frame 12d may be moved along another coordinate axis, which is practically the coordinate vertical line 13.
Step S4, controlling the opening area of the passage opening
The three door panels 20 are used to regulate the opening areas 23 of the access opening 12 during the process of the plate 30 entering and exiting the oven 10. The plurality of opening areas 23 provide and restrict movement of the plate member 30 through the passage opening 12, respectively. The opening areas 23 include a first opening area 231 (shown in fig. 2), a second opening area 232 (shown in fig. 4), and a third opening area 233 (shown in fig. 5).
The first opening area 231 is shown by three door panels 20 facing away from each other to open the largest area of the passage opening 12 (as shown in fig. 2). The second opening area 232 is defined by three door panels 20 according to the area specification of the panel 30 to be baked, such that the second opening area 232 can be presented when the two side edges 30b, 30c and the bottom edge 30d of the panel 30 are relatively close (as shown in fig. 4), and therefore the second opening area 232 must be substantially smaller than the first opening area 231 and relatively larger than the area of the panel 30, such that the panel 30 can smoothly pass through the access opening 12 along the second opening area 232 with minimum area gap, that is, the second opening area 232 is determined according to the area specification of the panel 30 to be baked. The third opening area 233 is presented by three closing actions of at least one door panel 20 of the door panels 20 (as shown in fig. 5), such that the third opening area 233 is relatively smaller than the first opening area 231 and the second opening area 232, and the third opening area 233 is only used by the transmission element 40 through the passage opening 12, and restricts the plate 30 from passing through the passage opening 12. In other words, the first opening area 231> the second opening area 232> the third opening area 233>0.
In addition, a soft curtain 50 (as shown in fig. 6) may be disposed on the top rim 12a of the opening 12 to flexibly cover the third opening area 233, but the soft curtain 50 allows the transmission element 40 to be disposed and moved through the opening 12, so that the soft curtain 50 can further reduce the heat energy in the oven 10 from being lost outwards through the opening 12 in the state of the third opening area 233.
In addition, referring to fig. 1b, the comparison method of the opening area including the controlled passage opening in the step S4 is further described, and the following steps S41 to S43 are sequentially performed. Wherein:
Step S41, setting the full-open area specification T1 of the passage port
The oven 10 is pre-configured with a control unit 15 configured by NC or PLC technology, and the oven 10 uses the control unit 15 to control the three actuating timings of the door panel 20, so as to control the first opening area 231, the second opening area 232, and the third opening area 233 of the access opening 12. Further, the control unit 15 has a full opening area specification T1 of the port 12 set in advance according to a predetermined specification of the oven equipment.
Step S42, obtaining the panel area specification T2
In the above step S4, the panel area specification T2 of the panel 30 waiting to be baked before actuating the first opening area 231, the second opening area 232 and the third opening area 233 of the door panel 20 can be obtained by one of the following steps S421 and S422, wherein:
In step S421, an operator uses the actual area specification (such as length, width or area) of the board 30 to be baked as the board area specification T2, and presets the board area specification T2 in the control unit 15 for storage, wherein the preset mode may be a mode that the operator directly inputs by using a keyboard, or a mode that the control unit 15 receives information of the board area specification to be baked in a Manufacturing Execution System (MES) in a connecting way, which belongs to an applicable range. Or alternatively
In step S422, a panel 30 is prepared for feeding to a feeding position (shown in fig. 9) by taking a panel measuring element 16 and installing the panel measuring element 16 outside the feeding port 12 of the oven 10, wherein the panel measuring element 16 can be constructed by a laser measuring device or a Charge Coupler (CCD), and the panel area specification T2 of the panel 30 is detected by the panel measuring element 16 and stored in the control unit 15.
S43, comparing the panel area specifications T1 and T2
The control unit 15 performs a comparison after obtaining the full opening area specification T1 and the panel area specification T2 according to the above step S421 or step S422, so as to calculate and obtain the actual distance between the coordinate vertical line 13 and the coordinate horizontal line 14 shown in fig. 2 for the first opening area 231, the second opening area 232 and the third opening area 233, and then execute the following step S44.
Step S44, the movable door plate presents the required opening area
The control unit 15 can further control the vertical driver 21 and the horizontal driver 22 (as shown in fig. 7) respectively configured by the three door panels 20 to drive the three door panels 20 to synchronously move to the actual positions of the required first opening area 231, the second opening area 232 and the third opening area 233 according to the actual distance obtained after comparing the surface area specifications in the step S43, and further, the three door panels 20 can synchronously move from the initial state to the position of the first opening area 231 according to the actual distance, and the first opening area 231 can be adjacent to or equal to the full opening area specification 23a (as shown in fig. 2) of the passage opening.
Subsequently, when the plate 30 is to be moved through the passage opening 12, the control unit 15 instructs the vertical driver 21 and the horizontal driver 22 to synchronously drive the three door panels 20 to move from the first opening area 231 to the second opening area 232 as required, so that the plate 30 can be moved through the passage opening 12 via the second opening area 232, and then enter the oven, change the temperature control cabin position of the oven, or discharge the oven. It should be noted that, in the second opening area 232 (as shown in fig. 4), the gaps 23a formed between the three edges of the door 20 surrounding the formed shape and the three edges of the panel 30 (i.e. the two edges 30b, 30c and the bottom edge 30 d) can be minimized, so as to prevent the heat energy in the panel channel 11 from being lost or dissipated to the adjacent temperature control cabin during the step-by-step movement of the panel 30 into/out of the oven or the temperature control cabin, thereby realizing the energy-saving optimization effect.
In addition, when the plate 30 is stationary and the passage opening 12 is not covered by the plate, the control unit 15 can instruct at least one vertical driver 21 or the horizontal driver 22 to drive at least one of the three door panels 20 (for example, the vertical door panel 20 a) to directly move from the first opening area 231 to the required third opening area 233 or from the second opening area 232 to the required third opening area 233, so as to completely close the passage opening 12, and prevent heat energy in the plate passage 11 from being lost or spilled into an adjacent temperature-controlled compartment, and at this time, the plate 30 cannot enter the oven, change the temperature-controlled compartment of the oven or be discharged out of the oven through the passage opening 12. Conversely, when the plate member 30 is to pass through the passage opening 12, the opening area 23 of the passage opening 12 is adjusted to the second opening area 232 by the third opening area 233, so that the plate member 30 can pass through the passage opening 12. Wherein the plate member 30, with or without passing through said passage opening 12, can be informed to the control unit 15 via a general sensing element (not shown) provided at or near said passage opening 12, and is described.
On the other hand, please refer to fig. 3, 7 and 8 in combination, the present invention also provides a door adjusting device for a panel oven, so that the door adjusting method of the panel oven can be easily implemented. The above-mentioned oven door adjusting device for a plate oven is used in the process of providing a quadrilateral plate for entering and exiting the oven, and comprises three movable door panels 20, wherein:
As shown in fig. 7, the three door panels 20 are respectively disposed on the three double side rims 12b, 12c and the bottom rim 12d of the opening 12, and the opening 12 is formed by extending a plate channel 11 (as shown in fig. 3) in the oven 10, so that the plate channel 11 can communicate with the outside through the opening 12.
As shown in fig. 3, the oven 10 in the present embodiment is a tunnel oven, the tunnel oven 10 has at least two ports 12 for loading and unloading the plate 30, particularly comprising a loading port 121 and a discharging port 122, and the ports 12 may further comprise at least one temperature-controlled cabin port 123 between the loading port 121 and the discharging port 122, so that the plate channel 11 can be connected between the loading port 121, the temperature-controlled cabin port 123 and the discharging port 122, and a plate moving track 111 is provided in the plate channel 11, the plate 30 enters the loading port 121 along the plate moving track 111 and can sequentially move in the isothermal cabin for standing, baking and drying through the temperature-controlled cabin port 123, and finally moves out of the oven 10 through the discharging port 122.
Referring to fig. 7 and 8, the top rim 12a of the passage opening 12 is provided with a transmission element 40, and the plate 30 is carried by the transmission element 40 to enter and exit the oven 10 along the plate moving track 111. The three movable door panels 20 are respectively disposed on the remaining three sides (i.e. the two sides 12b, 12c and the bottom 12 d) of the access opening 12, and driven by at least one driver to control the opening areas 23 of the access opening 12 during the process of the plate 30 entering and exiting the oven 10.
The three door panels 20 include a vertical door panel 20a and two lateral door panels 20b, wherein the vertical door panel 20a is slidably assembled to the bottom frame 12d of the access opening 12 along a vertical coordinate line 13, the two lateral door panels 20b are slidably assembled to the two lateral frame 12b, 12c of the access opening 12 along a horizontal coordinate line 14, and the vertical door panel 20a is disposed on the moving track 111 of the panel and is staggered adjacently to the two lateral door panels 20 b.
Further, the vertical door 20a is driven by a vertical driver 21 to move along the vertical coordinate line 13, so as to regulate the opening area 23, and the vertical driver 21 includes a motor 211 and at least one screw 212, and the screw 212 is driven by the motor 211 to rotate to drive the vertical door 20a to move. The two lateral door panels 20b are driven by at least one lateral driver 22 to move along the coordinate horizontal line 14, so as to regulate the opening area 23, the lateral driver 22 includes a plurality of lateral sliding rails 221 for providing sliding movement of the lateral door panels 20b, and a motor 222 for driving the lateral door panels 20b to slide along the lateral sliding rails 221, and the motor 222 drives a screw 223 to rotate so as to drive the lateral door panels 20b to move along the lateral sliding rails 221. The vertical drive 21 and the lateral drive 22 may be implemented as a motor and gear transmission arrangement or as a pneumatic cylinder.
Referring to fig. 5, the third opening area 233 may be implemented such that two of the side door panels 20b are in contact with each other, thereby restricting the movement of the panel 30 through the access opening 12. Further, when the two side door panels 20b are in contact with each other, a closing line 201 is formed, and the vertical door panels 20a can close the closing line 201 in a staggered manner. In addition, the third opening area 233 may be physically presented by a single movement of the vertical door panel 20 a. These are all within the technical scope of the invention as applicable.
In addition, referring to fig. 10, the method and apparatus are disclosed, wherein when the door is implemented as two door panels, the first opening area 231, the second opening area 232 and the third opening area 233 of the passage opening 12 can be controlled as well.
Further, in fig. 10, only two side door panels 20b are provided, but the vertical door panel 20a shown in fig. 2 is eliminated, so that when the second opening area 232 is controlled, the gap 23b larger than the gap 23a shown in fig. 4 is formed between the bottom rim 12d of the channel opening 12 and the bottom end 30d of the plate 30 due to no door panel covering, and the furnace temperature is easily leaked. However, since the two side edges 12b, 12c of the opening 12 have covered the opening areas of the two side edges 30b, 30c of the plate 30, respectively, the leakage of the furnace temperature can be reduced, and the effect is not as good as the three door panels shown in fig. 4, but still belongs to the technical scope of the invention. It should be noted that, in the two-way side door panel 20b shown in fig. 9, the first opening area 231 and the third opening area 233 can be controlled in the same manner as the three-way door panels described above.
In addition, regarding the shape and number of the door panels, the shape and number of the end edges of the panel, the shape of the channel opening and the number of the frame edges of the channel opening, if the door panels are simply divided or combined, the first to third opening areas of the present invention can be controlled, including the opening of the channel opening can be unfolded into the maximum opening area shape when the first opening area is opened, the furnace temperature can be reduced when the second opening area is opened, and the closing line can be generated when the third opening area is opened, which is an equivalent application of the present invention that can be easily modified or transformed.
The above description is illustrative of the invention and is not to be construed as limiting, and it will be understood by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
