DETAILED DESCRIPTION

[0047] 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.

[0048] 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.

[0049] 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 200 on the spindle is generally maintained more than 200 times a day. The maintenance work includes measuring the torque of the spindle chuck 200, disassembling and installing the spindle chuck 200, oiling the spindle chuck 200, 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 200 through a special tool, and then manually measure the torque of the spindle chuck 200 through a torque wrench or a tensile gauge. The torque setting value is 20Nm. At this value, the spindle chuck 200 is manually rotated through a torque wrench or a tensile gauge. If the torque measuring tool does not rotate, it means that the torque of the spindle chuck 200 has not decreased, otherwise it means that the chuck torque has decreased. If the torque of the spindle chuck 200 is reduced, it is necessary to manually disassemble the spindle chuck 200 through the tooling, and maintain, oil, and remove dust from the inner hole of the chuck. However, the spindle is a precision component. Improper operation during the manual disassembly and assembly of the chuck may damage the spindle, or the spindle chuck 200 may affect the processing performance due to the failure of the spindle chuck 200 to lock with the spindle. In addition, the manual replacement and removal of the spindle chuck 200 also have the problems of long replacement time, low replacement efficiency, and high operation difficulty. Therefore, there are many problems in manually measuring the torque of the spindle chuck 200, 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 shut down continuously to clean the inner hole of the spindle chuck 200 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 200 for continuous cleaning to be completed, which has the problems of long downtime, inconvenient operation for the large-format workbench 10, and cannot meet the continuous work requirements.

[0050] In view of this, an embodiment of the present application provides a spindle chuck torque detection device 100, aiming to overcome at least one of the above-mentioned technical problems.

[0051] Please also read Figure 1-4 The spindle chuck torque detection 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 torque detection device 100 mainly includes a lifting mechanism 110, a connecting structure 120 and a torque detector 130.

[0052] Among them, the lifting mechanism 110 is a component used for carrying and lifting in the spindle chuck torque detection device 100. On the one hand, the lifting mechanism 110 is used to carry other components such as the connecting structure 120 and the torque detector 130. On the other hand, the lifting mechanism 110 is used to move the connecting structure 120, the torque detector 130 and other components carried thereon to the target position so as to be able to maintain the spindle chuck 200.

[0053] Specifically, in some embodiments, 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. The driving part 111 can be a lifting mechanism 110 such as a cylinder, a ball screw, etc. 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 torque detection device 100 on the workbench 10, which is convenient for cooperating with the spindle chuck 200 to maintain it.

[0054] Among them, the connection structure 120 is arranged on the lifting mechanism 110, so that the connection structure 120 can be moved by the lifting mechanism 110. The connection structure 120 can be specifically arranged on the bearing part 112, and when the bearing part 112 is driven to move by the driving part 111, the connection structure 120 can move with the bearing part 112. The connection structure 120 can be moved and connected to the spindle chuck 200. It should be noted that the connection between the connection structure 120 and the spindle chuck 200 is a detachable connection. 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 different embodiments, the connection structure 120 can be connected by being sleeved or clamped on the spindle chuck 200.

[0055] The torque detector 130 is disposed on the lifting mechanism 110, and the torque detector 130 can be moved by the lifting mechanism 110. Specifically, the torque detector 130 can move with the bearing portion 112 of the lifting mechanism 110, so that it can move synchronously with the connecting structure 120. When the spindle chuck 200 is connected to the connecting structure 120, the torque detector 130 can be embedded in the inner hole of the spindle chuck 200, so that it can be clamped in the spindle chuck 200. The torque detector 130 is used to apply torque to the spindle chuck 200. When the torque detector 130 detects torque, the spindle chuck 200 applies torque to the torque detector 130.

[0056] Thus, by detecting the target torque of the spindle chuck 200 (generally 20Nm, which is determined according to the actual situation of the circuit board processing equipment) through the torque detector 130, it is possible to accurately determine whether the torque of the spindle chuck 200 is reduced according to whether the spindle chuck 200 rotates, and then accurately determine whether the spindle chuck 200 has sufficient clamping force. It can be known that when the torque detector 130 is clamped on the spindle chuck 200, the spindle chuck 200 is in a closed state of air cut-off, and the spindle chuck 200 can rotate under the drive of the spindle motor; if the torque detector 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 detector 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.

[0057] When the torque detector 130 is not clamped on the spindle chuck 200 , the spindle chuck 200 is in a ventilated open state, the spindle chuck 200 cannot rotate, and the disassembly tool 122 rotates to disassemble or install the spindle chuck 200 .

[0058] The torque of the spindle chuck 200 is driven by the driver of the spindle itself to drive the spindle chuck 200 to rotate, and the torque is detected by controlling the spindle chuck 200 to clamp the torque detector 130 to rotate.

[0059] The spindle chuck torque detection device 100 can detect the torque of the spindle chuck 200. The spindle chuck torque detection device 100 is set in the circuit board processing equipment, and there is no need to disassemble the spindle chuck 200, so that the torque of the spindle chuck 200 can be automatically detected, avoiding the problem of large errors caused by manual detection of the torque of the spindle chuck 200 and possible damage to the spindle chuck 200 due to improper operation.

[0060] In some embodiments, the connecting structure 120 can be fixedly connected to the bearing portion 112. The movement of the bearing portion 112 can drive the connecting structure 120 to move, and the spindle chuck 200 can be embedded in the limiting hole 121 of the connecting structure 120 to limit the rotational freedom of the spindle chuck 200.

[0061] Please also read Figure 1 to Figure 4In the first and second embodiments, the connection structure 120 includes a disassembly tool 122 and a gear set 123. The disassembly tool 122 is rotatably disposed on the bearing portion 112 of the lifting mechanism 110, so that it can rotate relative to the bearing portion 112, and the disassembly tool 122 can move with the bearing portion 112 to be sleeved on the spindle chuck 200, thereby realizing the connection between the connection structure 120 and the spindle chuck 200. The gear set 123 is disposed on the bearing portion 112 of the lifting mechanism 110, and the gear set 123 is connected to the disassembly tool 122. The gear set 123 is used to apply a rotational force to the disassembly tool 122 with the torque detector 130, so that when the torque detector 130 applies torque to the spindle chuck 200, the disassembly tool 122 limits the spindle chuck 200 to prevent it from rotating. Therefore, by providing the gear set 123 , a rotational force matching the torque can be accurately applied to the disassembly tool 122 according to the magnitude of the torque, thereby preventing the spindle chuck 200 from rotating.

[0062] Specifically, in some embodiments, the disassembly tool 122 has a limiting hole 121, which is formed in the disassembly tool 122. The shape of the limiting hole 121 matches the shape of the spindle chuck 200. When the disassembly tool 122 is sleeved on the spindle chuck 200, the spindle chuck 200 is embedded in the limiting hole 121. 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 disassembly tool 122, so that the torque detector 130 can be inserted into the limiting hole 121. When the spindle chuck 200 is embedded in the limiting hole 121, the torque detector 130 can be clamped in the spindle chuck 200.

[0063] Furthermore, in the first embodiment and the second embodiment, the gear set 123 is also used to drive the disassembly tool 122 to rotate, and the disassembly tool 122 rotates to remove or install the spindle chuck 200. Therefore, by providing the gear set 123, the gear set 123 provides a rotational force to the disassembly tool 122, driving the disassembly tool 122 to rotate, and then the spindle chuck 200 can be removed or installed.

[0064] In the first and second embodiments, the gear set 123 includes a power assembly 124, a driving 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 to provide rotational power. The driving wheel 125 is connected to the power assembly 124, and the driven wheel 126 is connected to the disassembly tool 122. The synchronous belt surrounds and connects the driving wheel 125 and the driven wheel 126. The power assembly 124 is used to apply a rotational force to the driving wheel 125, so that the driven wheel 126 applies a rotational force to the disassembly tool 122, thereby limiting the rotational freedom of the spindle chuck 200, and the spindle chuck 200 is never disassembled.

[0065] Specifically, the power assembly 124 includes a first motor 1241, a reducer 1242, and a power output shaft 1243. The reducer 1242 is connected to the first motor 1241 and is disposed on the bearing portion 112 of the lifting mechanism 110; the power output shaft 1243 is connected to the output end of the reducer 1242 and is connected to the driving 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 output shaft 1243 via its output end, thereby driving the driving wheel 125.

[0066] In the second embodiment,

[0067] Please refer again Figure 1 to Figure 4 In the first and second embodiments, the torque detector 130 includes a mounting seat 131 and a static torque sensor 132. The mounting seat 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 seat 131. When the spindle chuck 200 is connected to the connecting structure 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 mounting seat 131 is used to fix the static torque sensor 132,

[0068] It should be known that when the torque detector 130 is clamped on the spindle chuck 200 , the spindle chuck 200 is in a closed state with air cut off, and the spindle chuck 200 can rotate under the drive of the spindle motor;

[0069] When the torque detector 130 is not clamped on the spindle chuck 200 , the spindle chuck 200 is in a ventilated open state, the spindle chuck 200 cannot rotate, and the disassembly tool 122 rotates to disassemble or install the spindle chuck 200 .

[0070] 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. In this way, the user can understand the magnitude of the torque applied to the object by reading the torque value output by the signal processing unit.

[0071] In the embodiment of the present application, the mounting seat 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 .

[0072] In addition to the above-mentioned methods, the torque detector 130 may also use an adjustable torque motor (not shown). That is, in some embodiments, the torque detector 130 includes an adjustable torque motor, which is disposed on the bearing portion 112 of the lifting mechanism 110. 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 torque to the spindle chuck 200.

[0073] It should be noted that an adjustable torque motor is an electric motor that can adjust the output torque, and it can provide different torque outputs as needed. 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.

[0074] Correspondingly, the embodiment of the present application also provides a circuit board processing equipment, which can specifically be a drilling machine, a milling machine, an engraving machine, a welding equipment and other equipment commonly used in circuit board processing.

[0075] Please refer again Figure 1 The circuit board processing equipment includes a workbench 10, on which a spindle chuck 200 and a spindle chuck torque detection device 100 are provided. The spindle chuck torque detection device 100 mainly includes: a lifting mechanism 110, a connecting structure 120 and a torque detector 130. The connecting structure 120 is arranged on the lifting mechanism 110, and the connecting structure 120 can be moved and connected to the spindle chuck 200 through the lifting mechanism 110; the torque detector 130 is arranged on the lifting mechanism 110 and penetrated through the limiting hole 121; when the spindle chuck 200 is connected to the connecting structure 120, the torque detector 130 can be clamped in the spindle chuck 200; wherein, the torque detector 130 is used to detect the torque of the spindle chuck 200, and when the torque detector 130 detects the torque, the spindle chuck 200 rotates and applies torque to the torque detector 130.

[0076] It should be noted that the circuit board processing equipment can have all the technical features of the spindle chuck torque detection device 100 in the embodiment of the present application. The technical features and technical effects of the spindle chuck torque detection device 100 have been described above and will not be repeated here. In particular, by setting the spindle chuck torque detection device 100 in the circuit board processing equipment, the torque of the spindle chuck 200 can be automatically detected without disassembling the spindle chuck 200, avoiding the problem of large errors due to manual detection of the torque of the spindle chuck 200 and possible damage to the spindle chuck 200 due to improper operation.

[0077] Accordingly, the embodiment of the present application also provides a spindle chuck 200 maintenance method, comprising:

[0078] The driving part 111 of the lifting mechanism 110 drives the bearing part 112 to move, driving the connecting structure 120 to move, so that the connecting structure 120 is sleeved on the spindle chuck 200, so that the spindle chuck 200 is embedded in the limiting hole 121 of the connecting structure 120; the spindle chuck 200 clamps the torque detector 130;

[0079] The torque detector 130 applies torque to the spindle chuck 200 , and the torque of the spindle chuck 200 is detected by rotating the spindle chuck 200 .

[0080] See also Figure 2 During the processing of the circuit board processing equipment, when it is necessary to detect the torque of 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 to determine whether the torque of the spindle chuck 200 is reduced according to whether the torque detector 130 rotates. The torque of the spindle chuck 200 can be automatically detected without disassembling the spindle chuck 200, avoiding the problem of large errors due to manual detection of the torque of the spindle chuck 200 and possible damage to the spindle chuck 200 due to improper operation.

[0081] In some embodiments, when the spindle chuck 200 needs to be disassembled or installed, the connecting structure 120 is moved so that the disassembly tool 122 of the connecting structure 120 is sleeved on the spindle chuck 200; the gear set 123 of the connecting structure 120 drives the disassembly tool 122 to rotate to disassemble or install the spindle chuck 200.

[0082] See also Figure 1 During the processing of the circuit board processing equipment, when the spindle chuck 200 needs to be disassembled or installed, the spindle is controlled to move above the spindle chuck torque detection device 100, and then the above steps are performed to disassemble or install the spindle chuck 200.

[0083] The spindle chuck torque detection device 100 and circuit board processing equipment provided in the embodiment of the present application can realize the automatic measurement of the torque peak of the spindle chuck 200, without the need for workers to manually measure with tooling, with fast measurement speed and high efficiency, ensuring the safety of workers and saving human resources. It can also avoid the problems of inaccurate measurement of the clamping force of the spindle chuck 200 due to excessive manual measurement errors, affecting the processing accuracy, etc. It can realize the automatic disassembly and installation of the spindle chuck 200, without the need for direct operation by workers, with fast disassembly speed and high efficiency, ensuring the safety of workers and saving human resources. At the same time, it also improves the quality and reliability of the equipment disassembly and installation operations. It can realize the automatic cleaning of the inner hole of the spindle chuck 200, reduce the time for cleaning the inner hole of the spindle chuck 200 and reduce the standby time of the processing equipment, and there is a lot of room for improvement for the problem that large tables are not easy to operate.
