[0002] During the production of circuit boards, circuit board processing equipment is usually required for drilling, milling, splitting, etc. Circuit board processing equipment generally uses a mechanical spindle, which clamps tools of different diameters through a spindle chuck. As the milling operation proceeds, the spindle chuck will wear out after being subjected to force, and the dust generated by the milling operation is also easy to enter the inner hole of the spindle chuck, resulting in a decrease in the clamping force of the spindle chuck and a decrease in accuracy, thereby affecting the processing accuracy.

DETAILED DESCRIPTION

[0075] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0076] In the description of the present application, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In the description of the present application, "plurality" means two or more, and at least one means one, two, or more than two, unless otherwise clearly and specifically defined.

[0077] The applicant noted that the spindle of the circuit board processing equipment is a mechanical spindle. In order to ensure the processing accuracy, the spindle chuck on the spindle is generally maintained 2 to 3 times a day. Maintenance work includes measuring the torque of the spindle chuck, disassembling and installing the spindle chuck, oiling the spindle chuck, and cleaning dust. Ensure the tool clamping stability of the mechanical spindle, improve the dynamic processing performance of the spindle, and then ensure the processing accuracy of the machine. Specifically, the current maintenance of the spindle of the circuit board processing equipment is mainly to fix the spindle chuck with a special tool, and then manually measure the torque of the spindle chuck with a torque wrench or a tensor gauge. The torque setting value is 2Nm. At this value, the spindle chuck is manually rotated by a torque wrench or a tensor gauge. If the torque measuring tool does not rotate, it means that the torque of the spindle chuck has not decreased, otherwise it means that the torque of the chuck has decreased. If the torque of the spindle chuck decreases, it is necessary to manually disassemble the spindle chuck through the tooling, maintain, oil, and remove dust from the inner hole of the chuck. However, the spindle is a precision component. Improper operation during manual disassembly and assembly of the chuck may damage the spindle, or the processing performance may be affected due to the failure of the spindle chuck to lock with the spindle. In addition, manual replacement and removal of the spindle chuck also have the problems of long replacement time, low replacement efficiency and high difficulty in operation. Therefore, there are many problems in manually measuring the torque of the spindle chuck, installing and removing the chuck, and removing dust from the inner hole of the chuck. In addition, the circuit board processing equipment needs to be constantly stopped to clean the inner hole of the spindle chuck during operation, but currently these cleanings are all done manually. Manual operation requires a small brush to be inserted into the inner hole of the spindle chuck for continuous cleaning, which has the problems of long downtime, inconvenient operation for large-format workbenches, and inability to meet continuous work requirements.

[0078] In view of this, an embodiment of the present application provides a spindle chuck maintenance device, aiming to overcome at least one of the above-mentioned technical problems.

[0079] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 The spindle chuck maintenance device 100 of the embodiment of the present application can be applied to circuit board processing equipment to maintain the spindle chuck 200. In the embodiment of the present application, the spindle chuck maintenance device 100 mainly includes a lifting mechanism 110, a limiting mechanism 120 and a torque detection mechanism 130.

[0080] Among them, the lifting mechanism 110 is a component in the spindle chuck maintenance device 100 used for bearing and lifting. On the one hand, the lifting mechanism 110 is used to carry other components such as the limiting mechanism 120 and the torque detection mechanism 130. On the other hand, the lifting mechanism 110 is used to move the limiting mechanism 120, the torque detection mechanism 130 and other components carried thereon to the target position so as to be able to maintain the spindle chuck 200.

[0081] Specifically, the lifting mechanism 110 includes a driving part 111 and a bearing part 112, and the driving part 111 is used to drive the bearing part 112 to move. In some embodiments, the driving part 111 can be a driving mechanism such as a cylinder or a ball screw, 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, and the bearing part 112 can be a bearing plate. In addition, in practical applications, the driving part 111 can be assembled on the workbench 10 of the circuit board processing equipment to fix the spindle chuck maintenance device 100 on the workbench 10, so as to cooperate with the spindle chuck 200 to maintain it.

[0082] The limiting mechanism 120 is arranged on the bearing part 112, so that the limiting mechanism 120 can move with the bearing part 112. The limiting mechanism 120 can be connected to the spindle chuck 200 by moving. It should be noted that the connection between the limiting mechanism 120 and the spindle chuck 200 is a detachable connection. By moving the limiting mechanism 120, the limiting mechanism 120 can be connected to the spindle chuck 200, so as to limit the rotational freedom of the spindle chuck 200. Specifically, in different embodiments, the limiting mechanism 120 can be connected by being sleeved or clamped on the spindle chuck 200.

[0083] The torque detection mechanism 130 is disposed on the bearing portion 112, and the torque detection mechanism 130 can move with the bearing portion 112, so as to be able to move synchronously with the limiting mechanism 120. When the spindle chuck 200 is connected to the limiting mechanism 120, the torque detection mechanism 130 can be embedded in the inner hole of the spindle chuck 200, so as to be clamped in the spindle chuck 200. The torque detection mechanism 130 is used to apply torque to the spindle chuck 200, and the limiting mechanism 120 is used to limit the rotation of the spindle chuck 200 when the torque detection mechanism 130 applies the above torque.

[0084] Thus, the target torque (generally 2Nm, which is determined according to the actual situation of the circuit board processing equipment) is applied to the spindle chuck 200 by the torque detection mechanism 130. According to whether the torque detection mechanism 130 rotates, it is possible to accurately determine whether the torque of the spindle chuck 200 is reduced, and then accurately determine whether the spindle chuck 200 has sufficient clamping force. If the torque detection mechanism 130 rotates relative to the spindle chuck 200 when applying the target torque, it means that the torque of the spindle chuck 200 is weakened, that is, the clamping force of the spindle chuck 200 is weakened. If the torque detection mechanism 130 does not rotate relative to the spindle chuck 200 when applying the target torque, it means that the torque of the spindle chuck 200 is normal, that is, the clamping force of the spindle chuck 200 is normal.

[0085] The spindle chuck maintenance device can detect the torque of the spindle chuck 200. The spindle chuck maintenance device is set on the circuit board processing equipment. There is no need to disassemble the spindle chuck 200, so the torque of the spindle chuck 200 can be automatically detected, avoiding the problem of large errors caused by manual detection of the spindle chuck torque and possible damage to the spindle chuck due to improper operation.

[0086] In some embodiments, the limiting mechanism 120 can be fixedly connected to the bearing part 112. The movement of the bearing part 112 can drive the limiting mechanism 120 to move, and the spindle chuck 200 can be embedded in the limiting hole 121 of the limiting mechanism 120 to limit the rotational freedom of the spindle chuck 200.

[0087] Please also read Figure 2 to Figure 10 In the first and second embodiments, the limiting mechanism 120 includes a limiting sleeve 122 and a first rotating member 123. The limiting sleeve 122 is rotatably disposed on the bearing portion 112, so that it can rotate relative to the bearing portion 112, and the limiting sleeve 122 can move with the bearing portion 112 to be sleeved on the spindle chuck 200, thereby realizing the connection between the limiting mechanism 120 and the spindle chuck 200. The first rotating member 123 is disposed on the bearing portion 112, and the first rotating member 123 is connected to the limiting sleeve 122. The first rotating member 123 is used to apply a rotational force opposite to the torque of the torque detection mechanism 130 to the limiting sleeve 122, so that when the torque detection mechanism 130 applies torque to the spindle chuck 200, the limiting sleeve 122 limits the spindle chuck 200 from rotating. Therefore, by providing the first rotating member 123 , a rotational force matching the torque can be accurately applied to the limiting sleeve 122 according to the magnitude of the torque, thereby preventing the spindle chuck 200 from rotating.

[0088] Specifically, in some embodiments, the limiting sleeve 122 has a limiting hole 121, the limiting hole 121 is formed in the limiting sleeve 122, the shape of the limiting hole 121 is adapted to the shape of the spindle chuck 200, when the limiting sleeve 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 cooperate with the spindle chuck 200 to limit its rotational freedom. In addition, the limiting hole 121 can be set through the limiting sleeve 122, so that the torque detection mechanism 130 can be inserted into the limiting hole 121, and when the spindle chuck 200 is embedded in the limiting hole 121, the torque detection mechanism 130 can be clamped in the spindle chuck 200.

[0089] Further, in the first embodiment and the second embodiment, the first rotating member 123 is also used to drive the limiting sleeve 122 to rotate, and the limiting sleeve 122 rotates to remove or install the spindle chuck 200. Therefore, by providing the first rotating member 123, the first rotating member 123 provides a rotational force to the limiting sleeve 122, driving the limiting sleeve 122 to rotate, and then the spindle chuck 200 can be removed or installed.

[0090] Please also read Figure 3 to Figure 13 Different from the first embodiment, in the second embodiment, the spindle chuck maintenance device 100 further includes a dust removal mechanism 140 , and the dust removal mechanism 140 is used to remove dust from the spindle chuck 200 .

[0091] Specifically, the dust removal mechanism 140 is connected to the first rotating member 123, so that the dust removal mechanism 140 can move and rotate with the first rotating member 123. The dust removal mechanism 140 includes a dust removal part 141, and the movement of the limiting mechanism 120 will drive the dust removal mechanism 140 to move, so that the dust removal part 141 can be embedded in the spindle chuck 200. In addition, the dust removal mechanism 140 is driven to rotate by the rotation of the first rotating member 123, so that the dust removal part 141 can clean the spindle chuck 200. Specifically, the dust removal part 141 can be a brush, which is inserted into the inner hole of the spindle chuck 200 and rotated under the drive of the first rotating member 123 to achieve the cleaning of the spindle chuck 200.

[0092] It is understandable that in the second embodiment, by providing a dust removal mechanism 140 connected to the first rotating member 123 in the spindle chuck maintenance device 100, the bearing portion 112 can be moved to drive the limit mechanism 120 to move, and then drive the dust removal mechanism 140 to move, so that the dust removal portion 141 is inserted into the spindle chuck 200, thereby realizing automatic cleaning of the spindle chuck 200. Therefore, there is no need to manually clean the spindle chuck 200, which improves the cleaning efficiency, and also improves the safety and reliability, and reduces the labor cost.

[0093] Furthermore, in the second embodiment, the dust removal mechanism 140 also includes a dust suction assembly 142 for dusting the spindle chuck 200. The dust suction assembly 142 is connected to the first rotating member 123 so that it can move and rotate with the first rotating member 123. In addition, the dust suction assembly 142 has a dust suction joint 1421, and the dust removal part 141 is arranged in the dust suction joint 1421, so that when rotating, the dust suction joint 1421 can also limit the degree of freedom of the dust removal part 141 and improve its movement stability. The dust removal mechanism 140 moves so that the dust suction joint 1421 can be sleeved on the spindle chuck 200, so that the spindle chuck 200 can be dusted by the dust suction assembly 142. By setting up the dust suction component 142, it can cooperate with the dust removal part 141 to rotate and clean the fallen dust and the dust remaining in the deep inner hole of the spindle chuck 200 while sucking away the dust, thereby further improving the cleaning efficiency, improving the cleanliness of the spindle chuck 200, and then improving the stability of the operation of the spindle chuck 200, and improving the processing accuracy of the circuit board.

[0094] For details, please refer to Figure 4 The dust collection assembly 142 also includes a dust collection cover 1422 and a dust collection box 1423. The dust collection connector 1421 can be fixed to the dust collection cover 1422 by means of threads or other connection methods. The dust collection cover 1422 and the dust collection box 1423 are connected and fixed together. The dust collection connector 1421, the dust collection cover 1422 and the dust collection box 1423 are connected to form a closed negative pressure environment for dust collection. The dust collection box 1423 is connected to the first rotating member 123 to achieve movement and rotation.

[0095] In the first embodiment and the second embodiment, the first rotating member 123 includes a power assembly 124, a first synchronous wheel 125, a second synchronous wheel 126 and a synchronous belt 127. The power assembly 124 is disposed on the bearing portion 112, and is used to provide a power for rotation. The first synchronous wheel 125 is connected to the power assembly 124, the second synchronous wheel 126 is connected to the limiting sleeve 122, and the synchronous belt 127 surrounds and connects the first synchronous wheel 125 and the second synchronous wheel 126. The power assembly 124 is used to apply a rotational force to the first synchronous wheel 125, so that the second synchronous wheel 126 applies a rotational force to the limiting sleeve 122, thereby limiting the rotational freedom of the spindle chuck 200.

[0096] Specifically, the power assembly 124 includes a first motor 1241, a reducer 1242 and a power adapter 1243. The reducer 1242 is connected to the first motor 1241 and is disposed on the bearing portion 112; the power adapter 1243 is connected to the output end of the reducer 1242 and is connected to the first synchronous wheel 125. Thus, the first motor 1241 rotates, driving the reducer 1242 to rotate. After the reducer 1242 adjusts the speed, the rotational force is transmitted to the power adapter 1243 via its output end, thereby driving the first synchronous wheel 125. In the second embodiment, the dust removal mechanism 140 of the spindle chuck maintenance device 100 is connected to the power adapter 1243.

[0097] Please refer again Figure 2 to Figure 10 In the first and second embodiments, the torque detection mechanism 130 includes a second rotating member 131 and a static torque sensor 132. The second rotating member 131 is disposed on the bearing portion 112, and the static torque sensor 132 is connected to the driving end of the second rotating member 131. When the spindle chuck 200 is connected to the limiting mechanism 120 (in some embodiments, the spindle chuck 200 is embedded in the limiting hole 121), the static torque sensor 132 can be clamped in the spindle chuck 200. The second rotating member 131 is used to drive the static torque sensor 132, provide torque to the static torque sensor 132, and apply torque to the spindle chuck 200. The second rotating member 131 can be a motor, and the static torque sensor 132 is connected to the driving end of the motor.

[0098] It should be noted that the static torque sensor 132 is a sensor for measuring the torque of an object. It can measure the magnitude of the torque applied to an object in a stationary state. The static torque sensor 132 is usually composed of a torque sensor element and a signal processing unit. The torque sensor element usually uses strain gauges, capacitors, inductors or Hall effect principles to measure torque. When an object is subjected to torque, the sensor element will produce corresponding changes, such as the strain gauge will deform, the value of the capacitor or inductor will change, and the Hall effect sensor will produce a magnetic field change. These changes will be converted into electrical signals by the sensor element. The signal processing unit is responsible for receiving the electrical signal output by the sensor element, and performing amplification, filtering, linearization and other processing, and finally converting the torque value into a readable digital or analog signal.

[0099] In the embodiment of the present application, the second rotating member 131 can be used in conjunction with the static torque sensor 132 to apply torque to the spindle chuck 200 to detect the torque of the spindle chuck 200 .

[0100] In addition to the above-mentioned methods, the torque detection mechanism 130 can also use an adjustable torque motor (not shown).

Adjustable torque motors usually use DC motors or AC motors as drive sources. By adjusting parameters such as the motor's current, voltage or frequency, the motor's output torque can be adjusted. Choosing a suitable adjustable torque motor requires considering multiple factors, including the required torque range, speed requirements, power requirements, control methods, etc. In addition, factors such as the motor's efficiency, reliability, and cost also need to be considered. Depending on the requirements of the specific application, different types of adjustable torque motors can be selected, such as DC brushed motors, brushless motors, stepper motors, etc.
