Abstract
Description
Technical Field
[0001] This application relates to the field of assembly technology, specifically to an assembly device. Background Technology
[0002] The assembly equipment may include a first device and a second device. The first device is provided with a socket and the second device is provided with a pin. The assembly equipment assembles the first device and the second device to complete the crimping of the socket and the pin.
[0003] In the prior art, the fastening screw, knob, limit slider, and limit groove set in the fisheye needle crimping fixture can push the fixing plate to slide within the fixing frame, thereby fixing the PCB board within the fixing frame from both sides. This prevents the PCB board from shifting or shaking when the fisheye needle is crimped with it, resulting in a better crimping effect between the fisheye needle and the PCB board.
[0004] However, in the existing technology, the assembly accuracy during the assembly process of the first and second components is poor, and phenomena such as pin bending are prone to occur, which affects the assembly effect. Utility Model Content
[0005] The purpose of this application is to provide an assembly device that at least solves the problem of how to improve the assembly accuracy of the first device and the second device.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] In a first aspect, an assembly apparatus is provided for assembling a first device and a second device, the first device having a socket and the second device having a pin. The assembly apparatus includes a straightening mechanism for straightening the first device or the second device before the pin is inserted into the socket, so that the axis of the socket is aligned with the height direction of the pin.
[0008] Through the above technical solution, the assembly equipment provided in this application, by having a socket for the first component and a pin for the second component, allows the straightening mechanism to straighten the first or second component before the pin is inserted into the socket, so that the axis of the socket is aligned with the height direction of the pin. In this way, when assembling the first and second components, the pin can be accurately and smoothly inserted into the socket, avoiding the situation where the operator has not placed the first or second component flat in the initial state, resulting in the axis of the socket on the first component being inconsistent with the height direction of the pin on the second component, causing phenomena such as pin bending. This can improve the assembly accuracy of the first and second components and improve the crimping effect.
[0009] In some embodiments, the straightening mechanism includes a first gripper, a second gripper, and a first driving device connected to the first gripper and the second gripper. The first gripper includes a first limiting portion, and the second gripper includes a second limiting portion. The portion of the second device where the insertion pin is set is the insertion pin portion. The first driving device includes a first driving assembly and a second driving assembly. The first driving assembly is used to drive the first gripper and the second gripper to move in a direction closer to each other, so that the first limiting portion and the second limiting portion are located on the side of the first device facing the insertion pin portion. The second driving assembly is used to drive the first gripper and the second gripper to move in a direction away from the insertion pin portion, so as to push the opposite ends of the first device and make the axial direction of the insertion hole of the first device consistent with the height direction of the insertion pin.
[0010] Through the above technical solution, when the first device is aligned using the alignment mechanism, the first driving component can drive the first and second grippers to move in a closer direction to clamp and position both ends of the first device. The first and second limiting parts are then moved to the side of the first device facing the pin portion of the second device. Then, the second driving component drives the first and second grippers to move away from the pin portion, pushing the opposite ends of the first device and aligning the axial direction of the first device's insertion hole with the height direction of the pin. This ensures the alignment accuracy between the pin and the insertion hole, guaranteeing accurate and smooth insertion of the pin into the insertion hole. The cooperation of the first gripper, the second gripper, and the first driving device allows for positioning and alignment of multiple positions of the first device, improving the alignment effect.
[0011] In some embodiments, the first gripper further includes a third limiting portion, and the second gripper further includes a fourth limiting portion. The first limiting portion is connected to the third limiting portion, and the second limiting portion is connected to the fourth limiting portion. When the first gripper and the second gripper move toward each other, the third limiting portion and the fourth limiting portion limit the first device from opposite sides so that the socket of the first device is opposite to the pin of the pin portion.
[0012] With the above technical solution, when the first and second grippers move toward each other, the third and fourth limiting parts can clamp the first device from opposite sides to limit the first device in the first direction, further aligning the insertion hole of the first device with the pin of the insertion pin portion. This limiting method has a simple structure and is easy to implement.
[0013] In some embodiments, the first gripper and the second gripper are connected to the first drive assembly, the first drive assembly is connected to the second drive assembly, and the second drive assembly is used to drive the first drive assembly, the first gripper, and the second gripper to move away from the pin insertion location.
[0014] Through the above technical solution, the second driving component can drive the first driving component, the first gripper, and the second gripper to move away from the pin insertion location. This driving method has a simple structure and is easy to implement. Furthermore, this arrangement allows for a more rational arrangement of the first gripper, the second gripper, the first driving component, and the second driving component.
[0015] In some embodiments, the first driving device further includes a third driving component, the second driving component is connected to the third driving component, and the third driving component is used to drive the second driving component, the first driving component, the first gripper and the second gripper to move toward or away from the pin portion.
[0016] Through the above technical solution, the third driving component can drive the second driving component, the first driving component, the first gripper, and the second gripper to move towards or away from the pin portion. When straightening the first device, the third driving component can first drive the second driving component, the first driving component, the first gripper, and the second gripper to move towards the pin portion, so that the first limiting part and the second limiting part move to the side of the first device facing the pin portion. Then, the second driving component drives the first driving component, the first gripper, and the second gripper to move away from the pin portion, so that the first limiting part and the second limiting part contact the surface of the first device facing the pin portion. At the same time, the first driving component drives the first gripper and the second gripper to move towards the pin portion, clamping and positioning the first device. Finally, the second driving component drives the first gripper and the second gripper to move away from the pin portion, so that the first limiting part and the second limiting part lift the first device in the direction away from the pin portion, thereby straightening the first device. In this way, the cooperation of the third driving component and the second driving component can facilitate the movement of the first limiting part and the second limiting part to the side of the first device facing the pin, and can also facilitate the straightening of the first device.
[0017] This connection method is relatively simple and can simplify the structure of the straightening mechanism. Furthermore, this arrangement allows for a more rational layout of the first gripper, second gripper, first drive assembly, second drive assembly, and third drive assembly.
[0018] In some embodiments, the assembly equipment further includes a top limiting component disposed on the second driving component, and the second driving component is also used to drive the top limiting component, the first driving component, the first gripper and the second gripper to move toward the pin portion.
[0019] Through the above technical solution, the second driving component can drive the top limiting component, the first driving component, the first gripper and the second gripper to move towards the pin portion, so that the top limiting component limits the first device in the second direction, and the first gripper and the second gripper limit the first device in the first direction and straighten the first device. This can further increase the limiting position of the first device, improve the limiting effect of the first device, and prevent the operator from not placing the first device flat in the initial state, so that the axial direction of the insertion hole on the first device is consistent with the height direction of the pin on the second device.
[0020] In some embodiments, the top limiting assembly includes a carrier and a plurality of pressing rods disposed on the carrier, the plurality of pressing rods being used to contact the surface of the back-to-pin portion of the first device to press the first device.
[0021] Through the above technical solution, multiple pressing rods can press against the first device, so that the multiple pressing rods limit the side of the first device opposite to the insert pin, thereby further improving the limiting effect on the first device.
[0022] In some embodiments, the assembly equipment further includes a pressing device for applying a pressing force to the first device after the axial direction of the socket is aligned with the height direction of the pin, so as to drive the socket to engage with the pin.
[0023] With the above technical solution, after the axial direction of the socket is aligned with the height direction of the pin, the pressing device can apply a pressing force to the first device, thereby driving the socket and the pin to cooperate and realize the crimping of the first device and the second device, so as to ensure that the pin is crimped more stably in the socket and improve the connection effect between the pin and the socket.
[0024] In some embodiments, the pressing device includes a pressing head and a second driving device, the second driving device being used to drive the pressing head to move toward the first device to press the first device so that the socket engages with the pin.
[0025] Through the above technical solution, the second driving device can drive the pressure head to move closer to the first device, so that the pressure head presses the first device, thereby making the socket and the pin interference fit, and realizing the crimping of the first device and the second device.
[0026] In some embodiments, the pressure device further includes a pressure sensor for detecting the magnitude of the pressure applied by the pressure head to the first device.
[0027] Through the above technical solution, the pressure sensor can detect the pressure applied to the first device by the pressure head, so as to control the pressure between the socket and the pin, avoid excessive pressure that could damage the pin and the socket, and avoid insufficient pressure that could result in a loose connection between the pin and the socket, thereby ensuring the connection effect between the pin and the socket.
[0028] The beneficial effects of this application are:
[0029] (1) Through the above technical solution, the assembly equipment provided in this application, by providing a socket for the first device and a pin for the second device, the straightening mechanism can straighten the first device or the second device before the pin is inserted into the socket, so that the axial direction of the socket is consistent with the height direction of the pin. In this way, when the first device and the second device are assembled, the pin can be accurately and smoothly inserted into the socket, so as to avoid the phenomenon that the axial direction of the socket on the first device is inconsistent with the height direction of the pin on the second device due to the operator not placing the first device or the second device flat in the initial state, resulting in the pin bending phenomenon. This can improve the assembly accuracy of the first device and the second device and improve the crimping effect.
[0030] (2) Through the above technical solution, when the first device is straightened by the straightening mechanism, the first driving component can drive the first and second grippers to move in a closer direction to clamp and position both ends of the first device, and move the first and second limiting parts to the side of the first device facing the pin portion of the second device. Then, the second driving component drives the first and second grippers to move away from the pin portion to push the opposite ends of the first device and make the axial direction of the insertion hole of the first device consistent with the height direction of the pin. This can ensure the docking accuracy of the pin and the insertion hole, thereby ensuring that the pin can be accurately and smoothly inserted into the insertion hole. Through the cooperation of the first gripper, the second gripper and the first driving device, multiple positions of the first device can be positioned and straightened to improve the straightening effect of the first device.
[0031] (3) Through the above technical solution, when the first and second grippers move towards each other, the third and fourth limiting parts can clamp the first device from opposite sides to limit the first device in the first direction, further aligning the insertion hole of the first device with the insertion pin of the insertion pin portion. This limiting method has a simple structure and is easy to implement.
[0032] (4) Through the above technical solution, the second driving component can drive the first driving component, the first gripper, and the second gripper to move away from the pin insertion part. This driving method has a simple structure and is easy to implement. In addition, this arrangement can make the arrangement of the first gripper, the second gripper, the first driving component, and the second driving component more reasonable.
[0033] (5) Through the above technical solution, the third driving component can drive the second driving component, the first driving component, the first gripper, and the second gripper to move towards or away from the pin portion. When straightening the first device, the third driving component can first drive the second driving component, the first driving component, the first gripper, and the second gripper to move towards the pin portion, so that the first limiting part and the second limiting part move to the side of the first device facing the pin portion. Then, the second driving component drives the first driving component, the first gripper, and the second gripper to move away from the pin portion, so that the first limiting part and the second limiting part contact the surface of the first device facing the pin portion. At the same time, the first driving component drives the first gripper and the second gripper to move towards the pin portion, clamping and positioning the first device. Finally, the second driving component drives the first gripper and the second gripper to move away from the pin portion, so that the first limiting part and the second limiting part lift the first device in the direction away from the pin portion, thereby straightening the first device. In this way, the cooperation of the third driving component and the second driving component can facilitate the movement of the first limiting part and the second limiting part to the side of the first device facing the pin, and can also facilitate the straightening of the first device.
[0034] This connection method is relatively simple and can simplify the structure of the straightening mechanism. Furthermore, this arrangement allows for a more rational layout of the first gripper, second gripper, first drive assembly, second drive assembly, and third drive assembly.
[0035] (6) Through the above technical solution, the second driving component can drive the top limiting component, the first driving component, the first gripper and the second gripper to move towards the pin part, so that the top limiting component limits the second direction of the first device, and the first gripper and the second gripper limit the first direction of the first device and straighten the first device. In this way, the limiting position of the first device can be further increased, the limiting effect of the first device can be improved, and the operator can avoid the first device not being placed flat in the initial state, so that the axis of the insertion hole on the first device is consistent with the height direction of the pin on the second device.
[0036] (7) Through the above technical solution, multiple pressing rods can press the first device so that the multiple pressing rods limit the side of the first device facing away from the pin part, so as to further improve the limiting effect on the first device.
[0037] (8) Through the above technical solution, after the axial direction of the socket is consistent with the height direction of the pin, the pressing device can apply a pressing force to the first device, thereby driving the socket and the pin to cooperate and realize the crimping of the first device and the second device, so as to ensure that the pin is crimped more stably in the socket and improve the connection effect between the pin and the socket.
[0038] (9) Through the above technical solution, the second driving device can drive the pressure head to move closer to the first device so that the pressure head squeezes the first device, thereby making the socket and the pin interference fit, and realizing the crimping of the first device and the second device.
[0039] (10) Through the above technical solution, the pressure sensor can detect the pressure applied to the first device by the pressure head, so as to control the pressure between the socket and the pin, avoid excessive pressure that would damage the pin and the socket, and avoid insufficient pressure that would result in an unstable connection between the pin and the socket, thereby ensuring the connection effect between the pin and the socket.

It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.
[0048] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0049] Please see Figures 1 to 4 This application provides an assembly device 10 for assembling a first device 1 and a second device 2. The first device 1 has a socket 11, and the second device 2 has a pin 21. For example, the first device 1 can be a driver board, and the second device 2 can be a current sensor. The assembly device 10 is used to assemble the driver board and the current sensor.
[0050] In some examples, the first device 1 and the second device 2 can be assembled by crimping, while in other examples, the first device 1 and the second device 2 can also be assembled by welding. This application is exemplarily described using crimping as the assembly method for the first device 1 and the second device 2.
[0051] In some examples, pin 21 can be a fisheye pin.
[0052] In some embodiments, there can be multiple sockets 11 and multiple pins 21, and one pin 21 can be inserted into one socket 11. In this way, electrical connection can be achieved by crimping multiple sockets 11 and multiple pins 21, thereby improving the connection effect.
[0053] In some examples, the number of sockets 11 and pins 21 can both be 5. In other examples, the number of sockets 11 and pins 21 can also be other numbers, such as 3, 6, 8, etc. This application does not make specific limitations on this.
[0054] In some embodiments, the first device 1 is further provided with a plurality of positioning holes 12, and the second device 2 is further provided with a plurality of positioning posts 22. The plurality of positioning holes 12 are located on the side of the first device 1 near the second device 2, and the axial direction of the positioning holes 12 is consistent with the axial direction of the insertion hole 11. The plurality of positioning posts 22 are used to insert and cooperate with the plurality of positioning holes 12. In this way, the first device 1 and the second device 2 can be positioned by the cooperation of the plurality of positioning holes 12 and the positioning posts 22, so as to improve the assembly efficiency of the first device 1 and the second device 2.
[0055] In some examples, multiple positioning holes 12 and multiple positioning posts 22 can all be along a first direction (e.g., Figure 2 The arrangement can be in direction A). The first direction can be the length of the drive board.
[0056] In some examples, there can be two positioning holes 12 and two positioning posts 22. In other examples, there can be other numbers of positioning holes 12 and two positioning posts 22. This application does not make any specific limitation on this.
[0057] In some embodiments, the assembly equipment 10 may include a straightening mechanism 3, which is used to straighten the first device 1 or the second device 2 before the pin 21 is inserted into the socket 11, so that the axial direction of the socket 11 is aligned with the height direction of the pin 21.
[0058] In this way, by providing a socket 11 for the first device 1 and a pin 21 for the second device 2, the straightening mechanism 3 can straighten the first device 1 or the second device 2 before the pin 21 is inserted into the socket 11, so that the axial direction of the socket 11 is consistent with the height direction of the pin 21. Thus, when assembling the first device 1 and the second device 2, the pin 21 can be accurately and smoothly inserted into the socket 11. This avoids the situation where the operator does not place the first device 1 or the second device 2 flat in the initial state, which would cause the axial direction of the socket 11 on the first device 1 to be inconsistent with the height direction of the pin 21 on the second device 2, resulting in phenomena such as bending of the pin 21. This can improve the assembly accuracy of the first device 1 and the second device 2 and improve the crimping effect.
[0059] In some examples, the straightening mechanism 3 is used to straighten the first device 1, and in other examples, the straightening mechanism 3 is used to straighten the second device 2. This application is illustrated by way of example, with the straightening mechanism 3 used to straighten the first device 1.
[0060] In some embodiments, the straightening mechanism 3 may include a first gripper 31, a second gripper 32, and a first driving device 33 connected to the first gripper 31 and the second gripper 32. The first gripper 31 includes a first limiting portion 311, and the second gripper 32 includes a second limiting portion 321. The portion of the second device 2 where the insertion pin 21 is set is the insertion pin portion 23. The first driving device 33 includes a first driving assembly 331 and a second driving assembly 332. The first driving assembly 331 is used to drive the first gripper 31 and the second gripper 32 to move in a direction that brings them closer together (i.e., a first direction), so that the first limiting portion 311 and the second limiting portion 321 are located on the side of the first device 1 facing the insertion pin portion 23 (e.g., ...). Figure 2 (The lower side of the first device 1). For example, the pin portion 23 of the second device for connecting the pin 21 is located on one side of the drive board (first device 1) in the thickness direction. For example, the pin portion 23 is located on the lower side of the drive board, and the side of the first device 1 facing the pin portion 23 is the lower side of the drive board.
[0061] The second drive assembly 332 is used to drive the first gripper 31 and the second gripper 32 in a direction away from the pin insertion portion 23 (i.e., the second direction, such as...). Figure 1 The first device 1 moves in direction B) to push the opposite ends of the first device 1 and align the axial direction of the insertion hole 11 of the first device 1 with the height direction of the insertion pin 21. The first limiting portion 311 of the first gripper 31 and the second limiting portion 321 of the second gripper 32 are at the same horizontal height in the second direction.
[0062] In this way, when the first device 1 is straightened by the straightening mechanism 3, the first driving component can drive the first gripper 31 and the second gripper 32 to move in a closer direction to clamp and position both ends of the first device 1. The first limiting part 311 and the second limiting part 321 are moved to the side of the first device 1 facing the pin portion 23 of the second device 2. Then, the second driving component 332 drives the first gripper 31 and the second gripper 32 to move away from the pin portion 23 to push the opposite ends of the first device 1 and align the axis of the insertion hole 11 of the first device 1 with the height direction of the pin 21. This ensures the alignment accuracy between the pin 21 and the insertion hole 11, thereby ensuring that the pin 21 can be accurately and smoothly inserted into the insertion hole 11. Through the cooperation of the first gripper 31, the second gripper 32, and the first driving device 33, multiple positions of the first device 1 can be positioned and straightened to improve the straightening effect of the first device 1.
[0063] In some other embodiments, the first limiting part 311 and the second limiting part 321 may also be located on the upper side of the pin portion 23 of the first device 1, that is, on the side opposite to the pin portion 23.
[0064] This application is illustrated by way of example with the first limiting part 311 and the second limiting part 321 located on the lower side of the first device 1 facing the pin portion 23.
[0065] In some embodiments, the first gripper 31 further includes a third limiting portion 312, and the second gripper 32 further includes a fourth limiting portion 322. The first limiting portion 311 is connected to the third limiting portion 312, and the second limiting portion 321 is connected to the fourth limiting portion 322. When the first gripper 31 and the second gripper 32 move toward each other, the third limiting portion 312 and the fourth limiting portion 322 limit the first device 1 from opposite sides, so that the insertion hole 11 of the first device 1 is opposite to the insertion pin 21 of the insertion pin portion 23.
[0066] In this way, by connecting the first limiting part 311 to the third limiting part 312 and the second limiting part 321 to the fourth limiting part 322, when the first gripper 31 and the second gripper 32 move towards each other, the third limiting part 312 and the fourth limiting part 322 can clamp the first device 1 from opposite sides to limit the first device 1 in the first direction, further aligning the insertion hole 11 of the first device 1 with the insertion pin 21 of the insertion pin portion 23. This limiting method has a simple structure and is easy to implement.
[0067] In some examples, the first limiting part 311 and the third limiting part 312 can be an integral structure, and the second limiting part 321 and the fourth limiting part 322 can also be an integral structure, for example, by processes such as bending and stamping. In other examples, the first limiting part 311 and the third limiting part 312 can be separate structures, and the second limiting part 321 and the fourth limiting part 322 can also be separate structures. For example, the first limiting part 311 and the third limiting part 312 can be connected by welding, or they can also be connected by snap-fitting, riveting, or other methods.
[0068] In some embodiments, the first gripper 31 and the second gripper 32 are connected to the first drive assembly 331, the first drive assembly 331 is connected to the second drive assembly 332, and the second drive assembly 332 is used to drive the first drive assembly 331, the first gripper 31 and the second gripper 32 to move away from the pin insertion portion 23.
[0069] In this way, by connecting the first gripper 31 and the second gripper 32 to the first drive assembly 331, and the first drive assembly 331 to the second drive assembly 332, the second drive assembly 332 can drive the first drive assembly 331, the first gripper 31, and the second gripper 32 to move away from the pin insertion part 23. This connection method is relatively simple and can simplify the structure of the straightening mechanism 3. In addition, this arrangement allows for a more rational arrangement of the first gripper 31, the second gripper 32, the first drive assembly 331, and the second drive assembly 332.
[0070] In some embodiments, the first drive assembly 331 may include a first power member 3311 and a first transmission member 3312, and the second drive assembly 332 may include a second power member 3321 and a second transmission member 3322. The second transmission member 3322 is connected to the second power member 3321 and to the first power member 3311, and the first transmission member 3312 is connected to the first power member 3311 and to the first gripper 31 and the second gripper 32. Thus, the second drive assembly 332 can drive the first drive assembly 331, the first gripper 31 and the second gripper 32 to move away from the pin insertion portion 23.
[0071] For example, the first power component 3311 and the second power component 3321 can be motors, and the first transmission component 3312 and the second transmission component 3322 can be synchronous belt and synchronous pulley structures, sprocket and chain structures, etc.
[0072] In other examples, the first drive component 331 may also be a two-way cylinder, a pneumatic slide, an electric actuator, etc.
[0073] In some embodiments, the first driving device 33 may further include a third driving component 333, and a second driving component 332 is connected to the third driving component 333. The third driving component 333 is used to drive the second driving component 332, the first driving component 331, the first gripper 31 and the second gripper to move toward or away from the pin insertion portion 23.
[0074] In this way, by connecting the second drive component 332 to the third drive component 333, the second drive component 332 to the first drive component 331, and the first drive component 331 to the first gripper 31 and the second gripper 32, the third drive component 333 can drive the second drive component 332, the first drive component 331, the first gripper 31, and the second gripper 32 to move towards or away from the pin insertion portion 23. When straightening the first device 1, the third drive component 333 can first drive the second drive component 332, the first drive component 331, the first gripper 31, and the second gripper 32 to move towards the pin insertion portion 23, so that the first limiting part 311 and the second limiting part 321 move to the side of the first device 1 facing the pin insertion portion 23. Then, the second drive component 332 drives the first drive component 331, the first gripper 31, and the second gripper 32 to move away from the pin insertion portion 23, so that the first limiting part 311 and the second limiting part 321 move towards the side of the first device 1 facing the pin insertion portion 23. Then, the second drive component 332 drives the first drive component 331, the first gripper 31, and the second gripper 32 to move away from the pin insertion portion 23, so that the first limiting part 311 and the second limiting part 321 move towards the side of the first device 1 facing the pin insertion portion 23. The first device 1 is brought into contact with the surface of the first device 1 facing the pin portion 23 by the second limiting part 321 and the third limiting part 332. Simultaneously, the first driving assembly 331 drives the first gripper 31 and the second gripper 32 to move closer together, clamping and positioning the first device 1. Finally, the second driving assembly 332 drives the first gripper 31 and the second gripper 32 to move away from the pin portion 23, causing the first limiting part 311 and the second limiting part 321 to lift the first device 1 in the direction opposite to the pin portion 23, thus straightening the first device 1. In this way, the cooperation of the third driving assembly 333 and the second driving assembly 332 facilitates both the movement of the first limiting part 311 and the second limiting part 321 to the side of the first device 1 facing the pin portion 23 and the straightening of the first device 1.
[0075] This connection method is relatively simple and can simplify the structure of the straightening mechanism 3. In addition, this arrangement allows for a more rational arrangement of the first gripper 31, the second gripper 32, the first drive assembly 331, the second drive assembly 332, and the third drive assembly 333.
[0076] In some examples, the third drive assembly 333 may include a third power component 3331 and a third transmission component 3332. The third transmission component 3332 is connected to the third power component 3331 and to the second drive assembly 332. The first drive assembly 331 is connected to the second drive assembly 332 and to the first gripper 31 and the second gripper 32. Thus, the third drive assembly 333 can drive the second drive assembly 332, the first drive assembly 331, the first gripper 31, and the second gripper to move towards or away from the pin insertion portion 23.
[0077] For example, the third power component 3331 can be a motor, and the third transmission component 3332 can be a synchronous belt and synchronous pulley structure, a sprocket and chain structure, etc.
[0078] In other examples, the third drive component 333 can also be a cylinder, a pneumatic slide, an electric actuator, etc.
[0079] The structure of the third drive component 333 can be the same as that of the second drive component 332.
[0080] In some embodiments, the assembly equipment 10 may further include a first frame 4 connected to the third drive assembly 333. The first frame 4 is disposed on the side of the third drive assembly 333 opposite to the second drive assembly 332 and is used to support the third drive assembly 333. The third drive assembly 333 is disposed between the first frame 4 and the second drive assembly 332.
[0081] In this way, by placing the third drive component 333 between the first frame 4 and the second drive component 332, the first frame 4 can support the third drive component 333, which also makes the arrangement of the first frame 4, the third drive component 333 and the second drive component 332 more reasonable.
[0082] In some embodiments, the assembly equipment 10 may further include a top limiting component 5, which is disposed on the second driving component 332. The second driving component 332 is also used to drive the top limiting component 5, the first driving component 331, the first gripper 31 and the second gripper 32 to move toward the direction close to the pin portion 23.
[0083] In this way, by setting the top limiting component 5 on the second driving component 332, and connecting the first driving component 331 to the second driving component 332 and connecting it to the first gripper 31 and the second gripper 32, the second driving component 332 can drive the top limiting component 5, the first driving component 331, the first gripper 31 and the second gripper 32 to move towards the pin portion 23, so that the top limiting component 5 limits the first device 1 in the second direction, and the first gripper 31 and the second gripper 32 limit the first device 1 in the first direction and straighten the first device 1. This can further increase the limiting position of the first device 1, improve the limiting effect of the first device 1, and prevent the operator from not placing the first device 1 flat in the initial state, so that the axial direction of the insertion hole 11 on the first device 1 is consistent with the height direction of the pin 21 on the second device 2.
[0084] In some embodiments, the top limiting assembly 5 may include a carrier 51 and a plurality of pressing rods 52 disposed on the carrier 51. The plurality of pressing rods 52 are used to contact the surface of the back-facing pin 21 portion of the first device 1 to press the first device 1.
[0085] Among them, a plurality of top pressure rods 52 are provided on the side of the bearing member 51 facing the first device 1, and are used to limit the surface contact with the back of the first device 1 pin 21.
[0086] In this way, the first device 1 can be pressed by multiple pressing rods 52, so that the multiple pressing rods 52 limit the side of the first device 1 facing away from the insert pin portion 23, so as to further improve the limiting effect on the first device 1.
[0087] In some examples, the multiple pressing rods 52 may include multiple sets of pressing rods 52, which are arranged along the width direction (i.e., the first direction) of the first device 1, and the pressing rods 52 in each set are arranged along the length direction (e.g., the first direction) of the first device 1. Figure 4 The components are arranged in the direction C. In this way, multiple sets of top pressure rods 52 can better limit the second direction of the first device 1.
[0088] For example, the number of top pressure rods 52 can be 4, or the number of top pressure rods 52 can be other than 4, such as 6, 8, 10, etc. This application does not specifically limit this.
[0089] In some embodiments, the assembly equipment 10 may further include a pressing device 6, which is used to apply a pressing force to the first device 1 after the axial direction of the socket 11 is aligned with the height direction of the pin 21, so as to drive the socket 11 to engage with the pin 21.
[0090] In this way, after the axial direction of the socket 11 is aligned with the height direction of the pin 21, the pressing device 6 can apply a pressing force to the first device 1, thereby driving the socket 11 to cooperate with the pin 21, realizing the crimping of the first device 1 and the second device 2, so as to ensure that the pin 21 is crimped more stably in the socket 11 and improve the connection effect between the pin 21 and the socket 11.
[0091] In some examples, the socket 11 and the pin 21 can be coupled with an interference fit.
[0092] In some embodiments, the pressing device 6 includes a pressing head 61 and a second driving device 62. The second driving device 62 drives the pressing head 61 to move toward the first device 1 to press the first device 1 so that the socket 11 engages with the pin 21. The pressing head 61 is located on the side of the second driving device 62 facing the first device 1.
[0093] In this way, the second driving device 62 can drive the pressure head 61 to move closer to the first device 1, so that the pressure head 61 presses the first device 1, thereby causing the socket 11 to be press-fitted with the pin 21, and realizing the crimping of the first device 1 and the second device 2.
[0094] In some examples, the second drive unit 62 can be a cylinder, a pneumatic slide, an electric actuator, etc.
[0095] In some embodiments, the pressing device 6 further includes a pressure sensor 63, which is used to detect the magnitude of the pressure applied by the pressing head 61 to the first device 1. The pressure sensor 63 is located on the side of the pressing head 61 facing away from the first device 1.
[0096] In this way, the pressure sensor 63 can detect the pressure applied to the first device 1 by the pressure head 61, so as to control the pressure between the socket 11 and the pin 21, avoid excessive pressure that could damage the pin 21 and the socket 11, and avoid insufficient pressure that could result in a loose connection between the pin 21 and the socket 11, thereby ensuring the connection effect between the pin 21 and the socket 11.
[0097] In some embodiments, the assembly equipment 10 may further include a second frame 7 connected to the second drive device 62. The second frame 7 is disposed on the side of the second drive device 62 opposite to the first drive device 33 and is used to support the second drive device 62. The second drive device 62 is disposed between the second frame 7 and the first drive device 33.
[0098] In this way, by placing the second drive device 62 between the second frame 7 and the first drive device 33, the second frame 7 can support the second drive device 62, which also makes the arrangement of the second frame 7, the first drive device 33 and the second drive device 62 more reasonable.
[0099] In some embodiments, the assembly equipment 10 may further include an IGBT module 8, which is disposed between the first device 1 and the second device 2.
[0100] In this way, by placing the IGBT module 8 between the first device 1 and the second device 2, the first device 1 and the second device 2 can work together to control the on / off state of the IGBT module 8.
[0101] In some examples, the first device 1, the second device 2, and the IGBT module 8 can be connected by welding or by fasteners such as bolts.
[0102] In some embodiments, the assembly equipment 10 may further include a tray 9 and a plurality of limiting blocks disposed on the tray 9. The tray 9 is connected to the IGBT module 8, and the plurality of limiting blocks are used to limit the IGBT module 8.
[0103] In this way, by connecting the tray 9 to the IGBT module 8, multiple limit blocks can limit the IGBT module 8, preventing the IGBT module 8 from moving back and forth on the tray 9.
[0104] Specifically, the assembly process of assembly equipment 10 is as follows:
[0105] First, the operator places the first device 1, the second device 2, and the IGBT module 8 on the tray 9. The IGBT module 8 is positioned by multiple limiting blocks on the tray 9, and the first device 1 and the second device 2 are positioned by multiple positioning posts 22. The third drive assembly 333 then starts working, driving the second drive assembly 332, the first drive assembly 331, the first gripper 31, and the second gripper 32 towards the insertion pin portion 23, so that the first limiting part 311 and the second limiting part 321 move to the side of the first device 1 facing the insertion pin portion 23. The third drive assembly 333 then stops working. The second drive assembly 332 then starts working, driving the first drive assembly 331, the first gripper 31, and the second gripper 32 to continue moving towards the insertion pin portion 23, so that the first limiting part 311 and the second limiting part 321 contact the surface of the first device 1 facing the insertion pin portion 23. The second drive assembly 332 then stops working. The first drive assembly 331 starts working, driving the first gripper 31 and the second gripper 32 to move in opposite directions along the first direction, so that the third limiting part 312 of the first gripper 31 and the fourth limiting part 322 of the second gripper 32 move to opposite sides of the first device 1, and the first drive assembly 331 stops working. The second drive assembly 332 starts working, driving the top limiting assembly 5, the first drive assembly 331, the first gripper 31 and the second gripper 32 to continue moving towards the insertion pin portion 23, and the multiple top pressure rods 52 limit the first device 1 in the second direction, and the second drive assembly 332 stops working. The first drive assembly 331 starts working, driving the first gripper 31 and the second gripper 32 to move in the same direction along the first direction, and the third limiting part 312 of the first gripper 31 and the fourth limiting part 322 of the second gripper 32 clamp the first device 1 from opposite sides, limiting the first device 1 in the first direction, and the first drive assembly 331 stops working. The second drive assembly 332 starts working, driving the first gripper 31 and the second gripper 32 to move away from the pin portion 23, so that the first limiting part 311 and the second limiting part 321 drive the first device 1 to lift in the direction away from the pin portion 23, thereby straightening the first device 1. This avoids the situation where the operator did not place the first device 1 flat in the initial state, causing the axis of the insertion hole 11 on the first device 1 to be inconsistent with the height direction of the pin 21 on the second device 2, resulting in phenomena such as bending of the pin 21. At this time, the second drive assembly 332 stops working. After straightening the first device 1, the axis of the insertion hole 11 of the first device 1 is now consistent with the height direction of the pin 21 of the second device 2. The second drive device 62 starts working, driving the pressure head 61 to move downward in the direction close to the first device 1. When the pressure sensor 63 detects the pressure applied to the first device 1 by the pressure head 61, the pressure head 61 contacts the first device 1, and the second drive device 62 immediately stops working.The first drive assembly 331 starts working, driving the first gripper 31 and the second gripper 32 to move in opposite directions along a first direction to release the first device 1. When the pressure sensor 63 detects that the pressure has reached the set value, the socket 11 and the pin 21 complete the interference fit, the first device 1 and the second device 2 are pressed together, and the first drive assembly 331 stops working. The second drive device 62 starts working, driving the pressure head 61 to move upward away from the first device 1 to remove the first device 1, the second device 2 and the IGBT module 8 from the assembly equipment 10.
