Description

Turning plate mechanism of laser engraving machine

technical field

The utility model relates to the technical field of a plate turning mechanism of a laser engraving machine, in particular to a plate that can be clamped to both sides of a plate so as to perform the action of turning over smoothly.

Background technique

With the rapid development of science and technology, all kinds of technological products become more and more complex, and the processing tends to be more precise and miniaturized. "Laser engraving" is to use laser to perform precise and tiny engraving on the surface of boards or circuit boards to produce specific patterns. , texture or number, etc., to meet the various needs of the process or marking. The engraving operation can be divided into single-sided engraving or double-sided engraving. If you want to use automation for double-sided engraving, you must use a machine to turn over a board (such as a circuit board).

At present, there are mainly two types of flipping mechanism of the machine: one is to hold the clamping device on one side of the circuit board, and then use the mechanism to drive the clamping device to rotate to achieve the flipping action of the circuit board, but the disadvantage is that : Because the circuit board is usually a large-area sheet, which is only clamped on one side, it is easy to cause the circuit board to break during the flipping process and cause serious injury. The other is fixed around the circuit board with a jig, such as a rigid frame, and then the jig is driven to rotate by a mechanism to achieve the purpose of turning over. The advantage of this method is that the circuit board will not break, and the disadvantage is Because: After processing or finishing, the circuit board must be placed in the frame or taken out from the frame by machine or manually, which increases the process, and because the frame is placed around the circuit board, when the circuit board is close to the edge area Engraving is not possible, which restricts engraving operations.

Detailed ways

As shown in Figure 1, it is a perspective view of the present utility model. The turnover mechanism of the utility model includes a conveying component 1 and a turnover component 2. The conveying component 1 is responsible for driving a plate (such as a circuit board) to move in a direction, and the turnover component 2 is installed at the conveying component 1. , to turn over the board that moves here.

The conveying assembly 1 includes a conveyor table 11 and at least two sets of conveyor belts 12 installed thereon, for the plates placed on the conveyor belts 12 to move in one direction, and the middle position of the conveyor table 11 is additionally installed Count guide wheel 13. During the conveying process, both sides of the panel are supported by the conveyor belt 12 to move, and the middle position is supported by the guide wheel 13 to facilitate the smooth advancement of the panel.

As shown in Figures 1 and 2, the turnover panel assembly 2 is installed on the conveyor platform 11, and includes a turning drive device 21 and two sets of auxiliary fixing devices 22, which are used for clamping and fixing on both sides of the panel , the overturning drive device 21 is used to drive the auxiliary fixing device 22 to turn over from 0 to 180 degrees. The overturn driving device 21 includes a power device 211 , a transmission shaft 212 and two sets of gears 213 . The power device 211 can be a servo motor or other rotating mechanisms to precisely control the rotation angle of the transmission shaft 212 . Each group of the gear sets 213 cooperates with a group of auxiliary fixing devices 22 to drive them to rotate smoothly. In this embodiment, the gear set 213 is composed of three gears (but not limited thereto), the first gear 2131 is installed on the transmission shaft 212, and the second gear 2132 is installed on the conveyor platform 11 , and the third gear 2133 is mounted on the rotating shaft of the body 220 of the auxiliary fixing device 22, and the gears mesh in sequence. In the auxiliary fixing device 22 , a positioning post 221 , a bracket 222 , and a pneumatic cylinder 223 are installed on a rotatable body 220 . The rotating shaft of the machine body 220 is installed on the conveyor platform 11 . The positioning column 221 is located on the path of the moving direction of the panel during conveying. In this embodiment, the positioning column 221 is located at the center of the body 220 and protrudes axially toward the direction of the conveyor belt 12 . The bracket 222 is an elongated cantilever, on which several cam wheels 2221 are installed. The bracket 222 mainly provides an average supporting force. The position of the cam wheels 2221 is at the same height as the upper surface of the conveyor belt 12 . The pneumatic cylinder 223 can control a protruding post 2231 to extend or retract in due time, and there is a distance between the protruding post 2231 and the bracket 222 , and the distance is less than or equal to the thickness of the board. As shown in Figure 3, the stud 2231 is tapered. When the stud 2231 is stretched out, its taper matches the cam wheel 2221, so that the positions on both sides of the plate 3 can be easily fixed, and the contact area is the smallest to avoid Damage to the circuit on the surface of the board. In addition, by cooperating with the positioning column 221, the panel 3 can be prevented from falling during the flipping process.

As shown in FIG. 4 , the plate 3 to be engraved continues to move in a forward direction driven by the conveyor belt 12 . At this time, the pneumatic cylinder 223 has not been actuated, and the protrusion 2231 is in a retracted state.

As shown in Figure 5, when the panel 3 moves to the area where the flip assembly 2 is located, the positioning column 221 first contacts the panel 3, and blocks the advancement of the panel 3, so that the panel 3 is in the correct position, Later, a laser (not shown in the figure) is used to project onto the first surface 31 of the panel 3 for engraving.

After the engraving operation on the first surface 31 is completed, the surface will be turned over to engrave the other surface. As shown in Figure 6, the pneumatic cylinder 223 is activated to extend the stud 2231, and the cam wheel 2221 of the bracket 222 cooperates with the stud 2231 to clamp on both sides of the plate 3 (as shown in Figure 3 shown), so that the follow-up action of the panel 3 can be synchronized with the auxiliary fixing device 22.

As shown in Figure 7, the turning drive device 21 is actuated, and the drive shaft 212 is driven by the power device 211 to rotate, and two sets of gear sets 213 are used to drive two sets of auxiliary fixing devices 22 to rotate synchronously, so as to facilitate the plate 3 It is turned over smoothly, and during the process, the positioning column 221 keeps in contact with the board 3 to prevent the board 3 from sliding down.

As shown in FIG. 8, when the overturning drive device 21 drives the auxiliary fixing device 22 to rotate to 180 degrees, the pneumatic cylinder 223 will act again to retract the stud 2231, so that the overturned panel 3 is Place it on the conveyor belt 12 on the other side.

As shown in FIG. 9 , the overturning driving device 21 then drives the auxiliary fixing device 22 to return to the original position. Then laser is used to engrave the second surface 32 of the board 3 . After completion, the conveyor belt 12 is sent to another processing area.

The above-mentioned are only the embodiments of the present disclosure, and cannot limit the implementation scope of the present disclosure. Generally, all equal changes and modifications made within the scope of the utility model patent application shall belong to the scope covered by the utility model patent.
