It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

In the description of the present application, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "outer", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present application. In the description of the present application, the meaning of "plurality" means two or more, and at least one means one, two or more, unless explicitly defined otherwise.

The applicant notes that the spindle of the circuit board processing apparatus is a mechanical spindle, and that the spindle chuck 200 on the spindle is typically maintained a plurality of times per day in order to ensure processing accuracy. Maintenance work includes measuring torque force on the spindle chuck 200, removing and installing the spindle chuck 200, oiling the spindle chuck 200, and cleaning dust. The stability of the clamping cutter of the mechanical main shaft is ensured, the dynamic machining performance of the main shaft is improved, and the machining precision of the machine is further ensured. Specifically, the main shaft maintenance of the current circuit board processing equipment mainly fixes the main shaft chuck 200 through a special tool, then manually measures the torque of the main shaft chuck 200 through a torque wrench or a tension meter, the torque set value is 20Nm, the main shaft chuck 200 is manually rotated through the torque wrench or the tension meter under the torque set value, if the torque tool is not rotated, the torque of the main shaft chuck 200 is not reduced, otherwise, the torque of the chuck is reduced. If the torque of the spindle chuck 200 is reduced, the spindle chuck 200 needs to be disassembled manually through a fixture, and the disassembled spindle chuck 200 is maintained, oiled and the inner hole of the chuck is dedusted. However, the spindle belongs to a precision component, and the spindle may be damaged due to improper operation in the process of manually assembling and disassembling the chuck, or the machining performance is affected due to the fact that the spindle chuck 200 cannot be locked with the spindle, in addition, the conditions of long replacement time, low replacement efficiency and high operation difficulty exist in manual replacement and disassembly of the spindle chuck 200, so that more problems exist in manual torque measurement of the spindle chuck 200, installation and disassembly of the chuck, and dust removal of the inner hole of the chuck. Moreover, the circuit board processing equipment requires continuous shutdown to clean the bore of the spindle chuck 200 during operation, however, these cleaning operations are currently performed manually. The manual operation is completed by extending the small brush into the inner hole of the main shaft chuck 200 for continuous cleaning, and the problems of long downtime, inconvenient operation for the large-format workbench 10 and incapability of meeting the continuous working requirement exist.

Accordingly, the present application provides a spindle chuck torque detecting device 100, which is designed to overcome at least one of the above-mentioned problems.

Referring to fig. 1-4 together, a spindle chuck torque detection device 100 according to an embodiment of the application can be applied to a circuit board processing apparatus for maintaining a spindle chuck 200. In the embodiment of the present application, the spindle chuck torque force detection device 100 mainly includes a lifting mechanism 110, a connection structure 120 and a torque force detector 130.

The lifting mechanism 110 is a component for carrying and lifting in the spindle chuck torque force detecting device 100, on one hand, the lifting mechanism 110 is used for carrying other components such as the connecting structure 120 and the torque force detector 130, and on the other hand, the lifting mechanism 110 is used for moving the other components such as the connecting structure 120 and the torque force detector 130 carried thereon to a target position, so that the spindle chuck 200 can be maintained.

Specifically, in some embodiments, the lifting mechanism 110 includes a driving portion 111 and a bearing portion 112, where the driving portion 111 is used to drive the bearing portion 112 to move. The driving part 111 may be a lifting mechanism 110 such as a cylinder or a ball screw, and the bearing part 112 may be a bearing plate, and the bearing part 112 is connected to the driving end of the driving part 111 so as to be driven by the driving part 111 to move. In practical applications, the driving portion 111 may be mounted on the table 10 of the circuit board processing apparatus, so that the spindle chuck torque detecting device 100 may be fixed to the table 10, and may be conveniently engaged with the spindle chuck 200 for maintenance.

Wherein, the connection structure 120 is disposed on the lifting mechanism 110, so that the connection structure 120 can move by the lifting mechanism 110. The connection structure 120 may be specifically disposed on the carrying portion 112, and may move along with the carrying portion 112 when the carrying portion 112 is driven by the driving portion 111 to move. The connection structure 120 can be connected to the spindle chuck 200 by moving, and the connection structure 120 and the spindle chuck 200 are detachably connected, and by moving the connection structure 120, the connection structure 120 can be connected to the spindle chuck 200, so that the degree of freedom of rotation of the spindle chuck 200 can be limited. Specifically, in various embodiments, the connection structure 120 may be configured to engage or clamp onto the spindle chuck 200.

The torsion detector 130 is disposed on the lifting mechanism 110, and the torsion detector 130 can move by the lifting mechanism 110. Specifically, the torsion detector 130 may move along with the bearing portion 112 of the lifting mechanism 110, so as to be capable of moving synchronously with the connection structure 120. When the spindle chuck 200 is connected to the connection structure 120, the torsion detector 130 can be fitted into the inner hole of the spindle chuck 200, and thus can be clamped in the spindle chuck 200. The torque detector 130 is used for applying a torque to the spindle chuck 200, and when the torque detector 130 detects the torque, the spindle chuck 200 applies the torque to the torque detector 130.

Accordingly, the torque detector 130 detects the target torque of the spindle chuck 200 (generally may be 20Nm, specifically determined according to the actual situation of the circuit board processing device), and according to whether the spindle chuck 200 rotates, it can accurately determine whether the torque of the spindle chuck 200 decreases, and further accurately determine whether the spindle chuck 200 has a sufficient clamping force. It will be appreciated that when the torque detector 130 is clamped to the spindle chuck 200, the spindle chuck 200 is in an air-break closed state, and the spindle chuck 200 can be rotated under the drive of the spindle motor, if the torque detector 130 rotates relative to the spindle chuck 200 when a target torque is applied, this indicates that the torque of the spindle chuck 200 is reduced, i.e., the clamping force of the spindle chuck 200 is reduced. If the torque detector 130 does not rotate relative to the spindle chuck 200 when the target torque is applied, it indicates that the torque of the spindle chuck 200 is normal, i.e., the clamping force of the spindle chuck 200 is normal.

When the torque force detector 130 is not clamped to the spindle chuck 200, the spindle chuck 200 is in a vent open state, the spindle chuck 200 cannot rotate, and the dismounting tool 122 rotates to enable the spindle chuck 200 to be dismounted or mounted.

The torque of the spindle chuck 200 is detected by controlling whether the spindle chuck 200 rotates or not by controlling the torque detector 130, and the spindle chuck 200 is driven by a driver of the spindle and rotates.

The main shaft chuck torque force detection device 100 can detect the torque force of the main shaft chuck 200, the main shaft chuck torque force detection device 100 is arranged on circuit board processing equipment, the main shaft chuck 200 torque force can be automatically detected without disassembling the main shaft chuck 200, and the problems that errors are large and the main shaft chuck 200 is possibly damaged due to improper operation caused by manual detection of the main shaft chuck 200 torque force are avoided.

In some embodiments, the connection structure 120 may be fixedly connected to the bearing portion 112, and the connection structure 120 may be driven to move by the movement of the bearing portion 112, so that the spindle chuck 200 is embedded in the limiting hole 121 of the connection structure 120, and the rotational freedom of the spindle chuck 200 is limited.

Referring to fig. 1 to fig. 4, in the first embodiment and the second embodiment, the connection structure 120 includes a disassembling tool 122 and a gear set 123. The disassembling tool 122 is rotatably disposed on the bearing portion 112 of the lifting mechanism 110, so as to rotate relative to the bearing portion 112, and the disassembling tool 122 can move along with the bearing portion 112 to be sleeved on the spindle chuck 200, so that the connection structure 120 and the spindle chuck 200 are connected. The gear set 123 is disposed on the carrying portion 112 of the lifting mechanism 110, and the gear set 123 is connected to the disassembling tool 122. The gear set 123 is configured to apply a rotational force to the dismounting tool 122 with the torque detector 130, so that the dismounting tool 122 limits the spindle chuck 200 from rotating when the torque detector 130 applies a torque to the spindle chuck 200. Therefore, by arranging the gear set 123, the rotating acting force matched with the torsion can be accurately applied to the disassembling tool 122 according to the torsion, and the spindle chuck 200 is prevented from rotating.

Specifically, in some embodiments, the disassembling tool 122 has a limiting hole 121, the limiting hole 121 is formed in the disassembling tool 122, the shape of the limiting hole 121 is matched with the shape of the spindle chuck 200, when the disassembling tool 122 is sleeved on the spindle chuck 200, the spindle chuck 200 is embedded in the limiting hole 121, and the hole wall of the limiting hole 121 can be matched with the spindle chuck 200 to limit the degree of freedom of rotation of the spindle chuck. And, spacing hole 121 can run through and set up in dismantling frock 122 to torsion detector 130 can wear to locate in spacing hole 121, when main shaft chuck 200 inlays in locating the spacing hole 121, torsion detector 130 can be held in main shaft chuck 200.

Further, in the first embodiment and the second embodiment, the gear set 123 is further configured to rotate the disassembling tool 122, and the disassembling tool 122 rotates to enable the spindle chuck 200 to be disassembled or assembled. Therefore, by providing the gear set 123, the gear set 123 provides a rotational force to the dismounting tool 122, and drives the dismounting tool 122 to rotate, so that the spindle chuck 200 can be dismounted or the spindle chuck 200 can be mounted.

In the first and second embodiments, the gear set 123 includes a power assembly 124, a drive wheel 125, and a driven wheel 126. The power assembly 124 is disposed on the bearing portion 112 of the lifting mechanism 110, and is used for providing rotary power, the driving wheel 125 is connected with the power assembly 124, the driven wheel 126 is connected with the disassembling tool 122, and the synchronous belt is connected with the driving wheel 125 and the driven wheel 126 in a surrounding manner. The power assembly 124 is configured to apply a rotational force to the driving wheel 125, so that the driven wheel 126 applies a rotational force to the dismounting tool 122, thereby limiting the rotational freedom of the spindle chuck 200, and the spindle chuck 200 is not dismounted.

Specifically, power assembly 124 includes a first motor 1241, a speed reducer 1242, and a power take-off shaft 1243. The speed reducer 1242 is connected to the first motor 1241 and disposed on the carrying portion 112 of the lifting mechanism 110, and the power output shaft 1243 is connected to an output end of the speed reducer 1242 and connected to the driving wheel 125. Thus, the first motor 1241 rotates to drive the speed reducer 1242 to rotate, and after the speed reducer 1242 adjusts the rotation speed, the rotation acting force is transmitted to the power output shaft 1243 via the output end of the speed reducer 1242, so as to drive the driving wheel 125.

In the case of the second embodiment of the present invention,

Referring again to fig. 1-4, in the first and second embodiments, the torque detector 130 includes a mounting base 131 and a static torque sensor 132. The mounting base 131 is disposed on the bearing portion 112 of the lifting mechanism 110, and the static torque sensor 132 is connected to the driving end of the mounting base 131. When the spindle chuck 200 is coupled to the coupling structure 120 (in some embodiments, the spindle chuck 200 is embedded within the limiting aperture 121), the static torque sensor 132 can be clamped within the spindle chuck 200. The mount 131 is used to secure the static torque sensor 132,

It should be noted that when the torque force detector 130 is clamped to the spindle chuck 200, the spindle chuck 200 is in an air-break closed state, and the spindle chuck 200 can rotate under the drive of the spindle motor;

The static torque sensor 132 is a sensor for measuring the torque of an object. It can measure the torque applied to an object in a stationary state. The static torque sensor 132 is typically comprised of a torque sensor element and a signal processing unit. Torque sensor elements typically employ the principles of strain gauge, capacitance, inductance, or hall effect to measure torque. When an object is subjected to torque, the sensor element changes accordingly, for example, the strain gauge deforms, the capacitance or inductance changes, and the hall effect sensor changes magnetic field. These changes are converted into electrical signals by the sensor element. The signal processing unit is responsible for receiving the electric signal output by the sensor element, performing amplification, filtering, linearization and the like, and finally converting the torque value into a readable digital or analog signal. Thus, the user can know the torque received by the object by reading the torque value output by the signal processing unit.

In the embodiment of the present application, the mounting base 131 may be used in combination with the static torque sensor 132 to apply a torsion force to the spindle chuck 200, so as to implement detection of the torsion force of the spindle chuck 200.

In addition to the above, the torque detector 130 may employ an adjustable torque motor (not shown). That is, in some embodiments, the torque detector 130 includes an adjustable torque motor disposed on the bearing portion 112 of the lifting mechanism 110, and when the spindle chuck 200 is embedded in the limiting hole 121, the rotating shaft of the adjustable torque motor can be clamped in the spindle chuck 200 to apply a torque to the spindle chuck 200.

The adjustable torque motor is a motor capable of adjusting output torque, and can provide different torque outputs according to requirements. The adjustable torque motor generally employs a direct current motor or an alternating current motor as a driving source. The output torque of the motor can be adjusted by adjusting parameters such as current, voltage or frequency of the motor. The selection of an appropriate adjustable torque motor requires consideration of a number of factors, including the desired torque range, speed requirements, power requirements, control scheme, etc. In addition, factors such as efficiency, reliability, and cost of the motor need to be considered. Different types of adjustable torque motors, such as dc brush motors, brushless motors, stepper motors, etc., may be selected depending on the requirements of a particular application.

Correspondingly, the embodiment of the application also provides circuit board processing equipment, which can be equipment commonly used in circuit board processing such as drilling machines, milling machines, engraving machines, welding equipment and the like.

The connection structure 120 is disposed on the lifting mechanism 110, the connection structure 120 can move through the lifting mechanism 110 and be connected to the spindle chuck 200, the torsion detector 130 is disposed on the lifting mechanism 110 and penetrates through the limiting hole 121, the torsion detector 130 can be clamped in the spindle chuck 200 when the spindle chuck 200 is connected with the connection structure 120, wherein the torsion detector 130 is used for detecting torsion of the spindle chuck 200, and the spindle chuck 200 rotates and applies torsion to the torsion detector 130 when the torsion detector 130 detects torsion.

In particular, by arranging the main shaft chuck torque force detection device 100 on the circuit board processing equipment, the torque force of the main shaft chuck 200 can be automatically detected without disassembling the main shaft chuck 200, and the problems that the error is large and the main shaft chuck 200 is possibly damaged due to improper operation caused by manual detection of the torque force of the main shaft chuck 200 are avoided.

Correspondingly, the embodiment of the application also provides a maintenance method for the spindle chuck 200, which comprises the following steps:

The driving part 111 of the lifting mechanism 110 drives the bearing part 112 to move, drives the connecting structure 120 to move, and enables the connecting structure 120 to be sleeved on the main shaft chuck 200 so that the main shaft chuck 200 is embedded in the limiting hole 121 of the connecting structure 120;

a torsion is applied to the spindle chuck 200 by the torsion detector 130 and rotated by the spindle chuck 200 to detect the torsion of the spindle chuck 200.

Referring to fig. 2, in the processing of the circuit board processing apparatus, when the torque detection needs to be performed on the spindle chuck 200, the spindle is controlled to move above the spindle chuck torque detection device 100, and then the above steps are performed, and whether the torque of the spindle chuck 200 is reduced is determined according to whether the torque detector 130 rotates. The torque force of the main shaft chuck 200 can be automatically detected without disassembling the main shaft chuck 200, and the problems that the error is large and the main shaft chuck 200 is possibly damaged due to improper operation caused by manual detection of the torque force of the main shaft chuck 200 are avoided.

In some embodiments, when the spindle chuck 200 needs to be disassembled or assembled, the connection structure 120 is moved to enable the disassembling tool 122 of the connection structure 120 to be sleeved on the spindle chuck 200, and the gear set 123 of the connection structure 120 drives the disassembling tool 122 to rotate so as to disassemble or assemble the spindle chuck 200.

Referring to fig. 1, in the process of the circuit board processing apparatus, when the spindle chuck 200 needs to be disassembled or assembled, the spindle is controlled to move above the spindle chuck torque detecting device 100, and then the above steps are performed to disassemble or assemble the spindle chuck 200.
