Description

Technical Field

[0001] This invention relates to the field of automated processing equipment for reversing radars, and more particularly to a housing and pin assembly device for reversing radars. Background Technology

[0002] Reversing radar is an assembled part of a car; see appendix. Figure 1 As shown, a reversing radar 1 typically includes a housing 11 and pins 12. A circuit board is housed inside the housing, and the pins need to be inserted into the housing and soldered to the circuit board via cables 13. Because the soldering area between the circuit board and the cables is small, the pins must be properly inserted to ensure alignment between the cables and the soldering area. Furthermore, the housing must remain stationary during the soldering process to guarantee the assembly quality of the housing and pins. Therefore, how to perform high-precision soldering and assembly of the housing and pins in this process is a technical problem that needs to be solved. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a housing and pin assembly device for a reversing radar, which improves the positioning accuracy of the housing and the insertion accuracy of the pin, and meets the assembly requirements of the housing and pin.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a housing and pin assembly device for a reversing radar, comprising a turntable and a loading and unloading mechanism, a pin insertion mechanism and a pressing mechanism arranged sequentially along the rotation direction of the turntable; The turntable is fixed with a carrier for supporting the housing. The carrier includes a placement platform. The placement platform has a first placement cavity and a second placement cavity, each capable of holding only one housing. The placement platform is also provided with a first limiting component and a second limiting component located at the second placement cavity. The first limiting component includes a plurality of first elastic elements arranged in a rectangular shape. The first elastic elements extend into the second placement cavity and abut against the side wall of the housing. The first elastic elements deform under the compression of the housing to prevent the housing in the second placement cavity from shaking in the horizontal direction. The second limiting component includes two pressure plates symmetrically distributed relative to the second placement cavity. The pressure plates include pressing parts and abutting parts distributed vertically. The middle part of the abutting part is hinged to the placement platform. A second elastic element is provided between the lower part of the abutting part and the placement platform. The second elastic element is used to limit the pressing part to a first position when the abutting part is not pressed. The pressing part in the first position presses the housing downward against the placement platform. The loading and unloading mechanism includes two pressing components distributed along the rotation direction of the turntable. The pressing components are used to press the pressing part to limit the clamping part to a second position when the carrier passes by. In the second position, the clamping part swings outward from the second placement cavity to intersect with the second placement cavity.

[0005] The beneficial effects of this invention are as follows: The first placement cavity on the carrier achieves coarse positioning of the housing, facilitating loading and unloading. The second placement cavity achieves fine positioning of the housing, preparing for subsequent pin insertion.

[0006] The first limiting component uses a first elastic element to define the position of the housing in the horizontal plane, preventing the housing from swaying. Combined with the second limiting component, after the pressure plate presses the housing downwards, it further prevents the housing from swaying in the horizontal plane while simultaneously limiting the housing vertically. When not subjected to external pressure, the second limiting component uses the elastic force of the second elastic element to drive the pressing part to swing towards the second placement cavity, ensuring that the pressing part can press the housing downwards and maintains this downward pressure even as the turntable rotates. The cooperation of the first and second limiting components improves the stability of the housing placed in the second placement cavity. Even when the turntable rotates, the housing will not wobble within the second placement cavity, improving the housing's accuracy and ensuring precise alignment during subsequent insertion of the housing and pins.

[0007] The pressure plate is pressed down by the vehicle as it passes, and the pressure plate can be driven to swing without additional power.

[0008] The pins may not be properly inserted if they are only inserted through the pin insertion mechanism. In this case, directly soldering the pins to the circuit board inside the housing may result in a dry solder joint. Therefore, a pressing mechanism is set up to press the pins inserted into the housing into place.

[0009] Furthermore, the top-pressing assembly includes a first fixed frame, on which two spaced-apart cam followers are provided, and a channel for the carrier to pass through is formed between the two cam followers; The two cam followers can respectively abut against the pressing parts of the two pressure plates. When the pressing part just abuts against the roller of the cam follower, the cam follower pushes the pressure plate to swing until the pressing part is in the second position.

[0010] The pressure assembly does not rotate synchronously with the turntable, and no longer requires a drive component. When the carrier rotates with the turntable, it passes through the cam follower, which converts the rotational motion into linear motion, directly driving the pressure plate to swing.

[0011] Furthermore, the clamping part and the abutting part form an angle with an opening facing the second placement cavity, and a portion of the abutting part extends out of the placement platform; the second elastic element is a spring, one end of which is fixed to the placement platform and the other end to the abutting part. When the abutting part is pressed by the pressing assembly, the spring allows the clamping part to move to the second position. The clamping part and the abutting part forming the angle can use the preload of the spring to limit the clamping part to the first position, ensuring that the pressure plate is under constant pressure.

[0012] Furthermore, the pressing part includes an outer wall that abuts against the cam follower. The outer wall comprises a transition section one, a pressing section, and a transition section two, sequentially arranged along the turning direction of the turntable. Transition section one and transition section two are inclined in opposite directions, moving away from each other starting from the pressing section. Transition section one acts as a ramp; as the cam follower rolls in along the ramp, the pressing part is gradually pushed, dispersing the impact force throughout the stroke, achieving flexible loading. Similarly, transition section two enables the slow reset of the pressure plate. After passing the pressing section, the follower can smoothly reduce the interference fit via the ramp, allowing the pressing part to return smoothly under the action of the spring.

[0013] Furthermore, the first elastic element is a sealing ring, and four sealing rings are provided, each capable of abutting against one of the four corners of the housing. The sealing rings are compressed and deformed by the housing to generate a force that compresses the housing, thus limiting the displacement of the housing within the second placement cavity.

[0014] Furthermore, the placement platform has a notch corresponding to the sealing ring, and a portion of the sealing ring is embedded in the notch. A pivot hinged to the placement platform is located at the notch, and the sealing ring is fitted onto the pivot. The sealing ring and the placement platform are rotatably connected, reducing resistance during the process of removing the housing from the second placement cavity. When the housing enters or exits the second placement cavity, it pushes the sealing ring and the pivot to rotate around their axis.

[0015] Furthermore, the loading and unloading mechanism also includes a first robotic arm and a second robotic arm. The first robotic arm includes two gripping components, which are respectively used to transport an unprocessed shell into the first placement cavity and to remove a processed shell from the second placement cavity. The second robotic arm includes only one gripping component, used to place the shell from the first placement cavity into the second placement cavity. The first robotic arm is responsible for loading and unloading, while the second robotic arm is responsible for transferring the shell. Compared to a single robotic arm directly handling the shells between the conveyor line and the second placement cavity, this improves the efficiency of loading and unloading.

[0016] Furthermore, the pressing mechanism includes a first lifting drive component, which drives a first lifting frame to rise and fall. The first lifting frame is equipped with a pressure sensor and a pressing head. The pressing head can rise and fall synchronously with the first lifting frame and move up and down relative to it. Under the pressure of the pins, the pressing head can move upward relative to the first lifting frame and press against the pressure sensor. The pressure sensor detects the pressure applied by the pressing head and compares it with a set range. The pressing head and the lifting frame can slide relative to each other, forming a floating mechanism. Even if the exposed height of the pins after insertion into the housing is inconsistent, the pressing head can automatically retract its stroke to compensate for the height difference, ensuring that the final pressing force on each pin is completely consistent.

[0017] Furthermore, the first lifting frame includes a limiting part, in which the lower surface of the middle part of the pressing head abuts against the upper surface of the limiting part when the pressing head is not in contact with the pin, to prevent the pressing head from detaching from the first lifting frame due to its own weight.

[0018] Furthermore, the pin insertion mechanism includes a connecting component located outside the turntable and a third robotic arm. The connecting component is used to weld the pins and cables and transport the welded pins one by one to the third robotic arm. The third robotic arm inserts the pins welded to the cables into the housing located in the second placement cavity. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0022] See appendix Figure 2As shown, the assembly device for the housing 11 and pin 12 of the reversing radar 1 of the present invention includes a turntable 2 and a loading / unloading mechanism 4, a pin insertion mechanism 5 and a pressing mechanism 6 arranged sequentially along the rotation direction of the turntable 2. A carrier 3 for carrying the housing 11 is fixed on the turntable 2. When the turntable 2 rotates, a carrier 3 is sequentially transported to the loading / unloading mechanism 4, the pin insertion mechanism 5 and the pressing mechanism 6. The loading / unloading mechanism 4 is used to pick up and put the housing 11 on the carrier 3. The pin insertion mechanism 5 is used to insert the pin 12 into the housing 11 on the carrier 3. The pressing mechanism 6 is used to press the pin 12 inserted into the housing 11 into place.

[0023] See appendix Figure 4 Appendix Figure 5 As shown, the carrier 3 includes a placement platform 31, on which a first placement cavity 311 and a second placement cavity 312 are formed. Each of the first and second placement cavities 311 and 312 can only hold one housing 11, and their shapes match those of the housing 11. The placement platform 31 also has a first limiting component and a second limiting component 33 located at the second placement cavity 312. The first limiting component horizontally limits the position of the housing 11 within the second placement cavity 312, and the second limiting component 33 vertically limits the position of the housing 11 within the second placement cavity 312. The cooperation of the first and second limiting components 33 improves the stability of the housing 11 within the second placement cavity 312. Even if the turntable 2 rotates, the housing 11 will not wobble within the second placement cavity 312, improving the accuracy of the housing 11 within the second placement cavity 312 and ensuring precise alignment when the housing 11 and the pin 12 are subsequently inserted.

[0024] See appendix Figure 4 and attached Figure 6 As shown, the first limiting assembly includes a plurality of first elastic members 32 arranged in a rectangular shape. The first elastic members 32 extend into the second placement cavity 312 and abut against the side wall of the housing 11. At this time, the housing 11 compresses and deforms the first elastic members 32, and the first elastic members 32 limit the housing 11 within the second placement cavity 312 to prevent the housing 11 from shaking in the horizontal direction within the second placement cavity 312. The second limiting assembly 33 includes two pressure plates 331 symmetrically distributed relative to the second placement cavity 312. The pressure plates 331 include a pressing part 3311 and a pressing part 3312 distributed vertically. The middle part of the pressing part 3312 is hinged to the placement platform 31. A second elastic member 332 is provided between the lower part of the pressing part 3312 and the placement platform 31. The second elastic member 332 is used to limit the pressing part 3311 to a first position when the pressing part 3312 is not pressed. The pressing part 3311 in the first position presses the housing 11 downward onto the placement platform 31.

[0025] In this embodiment, the first limiting component uses the first elastic element 32 to limit the position of the housing 11 in the horizontal plane, preventing the housing 11 from swaying in the horizontal plane. Combined with the second limiting component 33, after the pressure plate 331 presses the housing 11 downwards, it further prevents the housing 11 from swaying in the horizontal plane while limiting it in the vertical direction. When not subjected to external pressure, the second limiting component 33 uses the elastic force of the second elastic element 332 to drive the pressing part 3311 to swing towards the second placement cavity 312, ensuring that the pressing part 3311 can press the housing 11 downwards, and always pressing the housing 11 downwards while the turntable 2 rotates.

[0026] See appendix Figure 3 As shown, the loading and unloading mechanism 4 includes a first robotic arm 41, a second robotic arm 42, and two pressing components 43. The two pressing components 43 are distributed along the rotation direction of the turntable 2, namely the first pressing component 43a and the second pressing component 43b. The first pressing component 43a and the second pressing component 43b have the same structure and are used to press the pressing part 3312 to limit the clamping part 3311 to a second position when the carrier 3 passes by. In the second position, the clamping part 3311 swings outward to the second placement cavity 312 until it intersects with the second placement cavity 312. Intersects mean that the projections of the clamping part and the second placement cavity on the same horizontal plane do not coincide. At this time, the pressing part 3312 no longer presses the housing 11 downward, and the housing 11 in the second placement cavity 312 can be picked up and put down by the first robotic arm 41 and the second robotic arm 42. The first robotic arm 41 is used to transport the unprocessed housing 11 from the conveyor line (not shown) to the first placement cavity 311. At this time, the carrier 3, which is pressed by the first pressing assembly 43a, is released from the pressure plate 331, and the processed housing 11 in the second placement cavity 312 is then transported back to the conveyor line by the first robotic arm 41. When the carrier 3 moves to the second pressing assembly 43b, the second pressing assembly 43b presses the carrier 3 again. At this time, the pressure plate 331 will not block the inlet and outlet of the second placement cavity 312. Then, the second robotic arm 42 is used to transport the housing 11 in the first placement cavity 311 to the second placement cavity 312.

[0027] The first robotic arm 41 and the first pressing assembly 43a cooperate to load and unload the housing 11. At this time, the first pressing assembly 43a presses the pressing part 3312 of the pressing plate 331, ensuring that the housing 11 processed in the second placement cavity 312 can be removed by the first robotic arm 41. The second robotic arm 42 and the second pressing assembly 43b cooperate to transfer the housing 11. When the second pressing assembly 43b presses the pressing part 3312 of the pressing plate 331, it ensures that the second robotic arm 42 can transport the housing 11 in the first placement cavity 311 to the second placement cavity 312. When the carrier 3 leaves the working area of ​​the second pressing assembly 43b along with the turntable 2, the pressing plate 331 is reset under the drive of the second elastic element 332, ensuring that the pressing part 3311 is pressed on the housing 11.

[0028] In this embodiment, the arrangement of the first robotic arm 41, the second robotic arm 42, and the two pressing components 43 improves the loading and unloading efficiency of the housing 11. When the carrier 3 moves to the working area of ​​the first robotic arm 41, the first robotic arm 41 can simultaneously load and unload the housing 11. After loading, the housing 11 is transferred to the working area of ​​the second robotic arm 42 and transported to the more precise second placement cavity 312 for subsequent assembly of the pins 12. In this process, the loading and unloading of the housing 11 is more continuous, and compared to having only one robotic arm, the waiting time is shorter and the assembly efficiency is higher.

[0029] See appendix Figure 4 As shown, the first elastic element 32 is a sealing ring, and four sealing rings are provided, which abut against the four corners of the housing 11 respectively. The sealing rings are vertically arranged and rotatably connected to the placement platform 31. Part of the sealing rings extends into the second placement cavity 312. When the housing 11 is placed in the second placement cavity 312, the sealing rings are compressed and deformed by the housing 11 to generate a force that compresses the housing 11, limiting the displacement of the housing 11 in the second placement cavity 312.

[0030] The placement platform 31 has a notch 313 corresponding to the sealing ring. Part of the sealing ring is embedded in the notch 313. A pivot is provided at the notch 313, which is hinged to the placement platform 31. The sealing ring is sleeved on the pivot to achieve a rotatable connection with the placement platform 31. The rotatable connection between the sealing ring and the placement platform 31 reduces the resistance during the process of taking the housing 11 out of the second placement cavity 312. When the housing 11 enters or exits the second placement cavity 312, it pushes the sealing ring and the pivot to rotate around the axis.

[0031] See appendix Figure 7 As shown, the clamping part 3311 and the pressing part 3312 form an angle with the opening facing the second placement cavity 312. A portion of the pressing part 3312 extends out of the placement platform 31 to ensure that it can be pressed by the pressing assembly 43. The second elastic member 332 is a spring, with one end fixed to the placement platform 31 and the other end fixed to the pressing part 3312. When the pressing part 3312 is pressed by the pressing assembly 43, the spring is continuously compressed, allowing the clamping part 3311 to move to the second position.

[0032] See appendix Figure 8As shown, the top-pressing assembly 43 does not rotate synchronously with the turntable 2. The top-pressing assembly 43 includes a first fixed frame 431, on which two spaced-apart cam followers 432 are provided. Two pressure plates 331 are located on both sides of the moving direction of the carrier 3, that is, radially distributed along the turntable 2. The two cam followers 432 are also located on both sides of the moving direction of the carrier 3, forming a channel for the carrier 3 to pass through between the two cam followers 432. The two cam followers 432 can respectively abut against the pressing parts 3312 of the two pressure plates 331. When the carrier 3 rotates to the point where the pressing part 3312 just abuts against the roller of the cam follower 432, the cam follower 432 pushes the pressure plate 331 to swing to the second position of the pressing part 3311.

[0033] In this embodiment, the pressing assembly 43 uses a cam follower 432 to press the pressure plate 331. When the pressure plate 331 passes the cam follower 432, the roller of the cam follower 432 rotates, which does not hinder the movement of the carrier 3. At the same time, when the pressing part 3312 of the pressure plate 331 and the cam follower 432 are in contact, since the position of the cam follower 432 remains unchanged, it pushes the pressing part 3311 protruding from the placement platform 31 toward the placement platform 31. At this time, the pressure plate 331 swings, and the pressing part 3311 moves to the second position, releasing the positioning of the housing 11. The pressing assembly 43 no longer needs a driving component. When the carrier 3 rotates with the turntable 2, when it passes the cam follower 432, the cam follower 432 converts the rotational motion into linear motion, directly driving the pressure plate 331 to swing.

[0034] In one embodiment, the pressing portion 3312 includes an outer wall that can abut against the cam follower 432, see Appendix Figure 7 As shown, the outer wall includes a transition section 33121, a pressing section 33122 and a transition section 33123 arranged sequentially along the moving direction of the turntable 2. The transition section 33121 and the transition section 33123 are inclined and in opposite directions. The transition section 33121 and the transition section 33123 move away from each other starting from the pressing section 33122.

[0035] Transition section one 33121 is equivalent to an inclined plane. As the cam follower 432 rolls in along the inclined plane, the pressing part 3312 is gradually pushed, and the impact force is distributed throughout the stroke, achieving flexible loading. Similarly, transition section two 33123 achieves the slow reset of the pressure plate 331. After passing through the pressing section 33122, the cam follower can smoothly reduce the interference through the inclined plane, allowing the pressing part 3312 to return smoothly under the action of the spring.

[0036] In one embodiment, the pressing section 33122 is an arc-shaped surface protruding toward the cam follower 432. In this case, the pressing section 33122 protrudes a large distance from the placement platform 31, which facilitates the pushing of the cam follower 432. Of course, the pressing section 33122 can also be a plane.

[0037] When the pressing part 3311 presses the housing 11, the minimum distance between the two pressing sections 33122 is greater than the minimum distance between the two cam followers 432. At this time, when the carrier 3 passes the cam follower 432, the cam follower 432 can abut against the pressing part 3312 and push the pressing part 3312 to move.

[0038] In one embodiment, the position of the cam follower 432 on the first fixed frame is adjustable to ensure that the cam follower 432 can move to an optimal position that contacts the pressing section 33122. For example, the cam follower 432 is fixed to the first fixed frame by bolts, and the first fixed frame is provided with a slotted hole for the bolt to move in. The cam follower 432 is positioned in the optimal position by sliding the bolt within the slotted hole.

[0039] In one embodiment, see Appendix Figure 9 As shown, both the first robotic arm 41 and the second robotic arm 42 include a movable arm 411 and a gripping assembly 412 fixedly connected to the movable arm 411. The gripping assembly 412 can grip a housing 11. The first robotic arm 41 includes two gripping assemblies 412, which are used to grip a housing 11 and place it into the first placement cavity 311 and to grip a housing 11 in the second placement cavity 312, respectively. The second robotic arm 42 includes only one gripping assembly 412, which is used to grip the housing 11 in the first placement cavity 311 and place it into the second placement cavity 312. The movable arm 411 can be a three-axis moving platform, a multi-axis robotic arm, etc., as long as it can meet the movement requirements of the gripping assembly 412. The gripping assembly 412 includes gripping cylinders and grippers, etc.

[0040] When the housing 11 arrives from the conveyor line, its position is often off. If it is directly placed into the second placement cavity 312 with precision positioning, it is easy to get stuck or damaged due to hard impact. The first placement cavity 311 in the carrier 3 serves as a transfer coarse positioning, and the second placement cavity 312 serves as the final fine positioning. Together with the first limit component and the second limit component 33, they perform high-precision correction. Through the handling of the second robot arm 42 at the second pressing component 43b, the housing 11 undergoes re-clamping and calibration, which ensures the positional accuracy of the subsequent pin insertion mechanism 5 when it is precisely inserted. The pressure plate 331 of the second limit component 33 presses the housing 11 tightly when it is not under pressure, which ensures the high-precision fixation of the housing 11. The housing 11 needs to be loosened when loading and unloading. Instead of equipping each carrier 3 with an independent drive component, a fixed top-pressing assembly 43 is used. Only when the carrier 3 moves to a specific work position does the top-pressing assembly 43 use a cam-type mechanical push to passively open the pressure plate 331. This achieves follow-up clamping, which not only ensures absolute stability during transportation but also allows for precise positioning when loading and unloading are required.

[0041] See appendix Figure 2 As shown, the pin insertion mechanism 5 includes a connecting component 51 located outside the turntable 2 and a third robotic arm 52. The connecting component 51 is used to solder the pins 12 and the cables 13 and to transport the soldered pins 12 one by one to the third robotic arm 52. The third robotic arm 52 inserts the pins 12 soldered with the cables 13 into the housing 11. After the third robotic arm 52 clamps the pins 12 and inserts them into the housing 11, the pins 12 may not be fully inserted. At this time, directly soldering the pins 12 to the circuit board inside the housing 11 may result in a dry solder joint. Therefore, the pressing mechanism 6 presses the pins 12 inserted into the housing 11 into place.

[0042] See appendix Figure 10 As shown, the pressing mechanism 6 includes a first lifting drive component 61, which drives the first lifting frame 62 to rise and fall. The first lifting frame 62 is equipped with a pressure sensor 63 and a pressing head 64. The pressing head 64 can rise and fall synchronously with the first lifting frame 62 and move up and down relative to it. The pressure sensor 63 is fixedly connected to the first lifting frame 62 and is located directly above the pressing head 64. The pressing head 64 can move upward relative to the first lifting frame 62 under the pressure of the pin 12. The pressure sensor 63 detects the pressure applied by the pressing head 64 and compares it with a set range.

[0043] When the pressing mechanism 6 presses the pin 12, the first lifting drive 61 drives the first lifting frame 62 to move downward until the pressing head 64 and the pin 12 come into contact. The first lifting frame 62 continues to descend. Since the pressing head 64 is slidable relative to the lifting frame, and the pressure sensor 63 is fixed on the lifting frame, when the pressing head 64 is subjected to the upward reaction force of the pin 12, the pressing head 64 will slide upward relative to the lifting frame until it contacts the pressure sensor 63. The pressure sensor 63 will then press the pressing head 64 downward, thereby pressing the pin 12 onto the housing 11. This relative motion transmits the force to the pressure sensor 63, which reads the pressure value. If the pressure value detected by the pressure sensor 63 is still less than the set range after the first lifting drive 61 drives the first lifting frame 62 to move downward by a set distance, the pin 12 is not pressed into place, and an abnormality is indicated. If the pressure value detected by the pressure sensor 63 exceeds the set range during the downward movement of the first lifting drive 61 and the first lifting frame 62, it indicates that the pin 12 is blocked and is not in the preset position, and an abnormality is indicated.

[0044] The first lifting drive 61 drives the first lifting frame 62 to descend as a whole. Under its own weight, the pressure head 64 is positioned at the lower end relative to the first lifting frame 62 and descends synchronously with it, until its lower end contacts the top of the pin 12. Since the pin 12 may not be fully in place, the first lifting frame 62 continues to descend, while the pressure head 64, subjected to the upward reaction force of the pin 12, begins to slide upward relative to the first lifting frame 62 against gravity. This continues until the pressure head 64 and the pressure sensor 63 on the first lifting frame 62 come into contact and cannot move further upward. The first lifting frame 62 then drives the pressure head 64 to continue descending until it reaches a set distance, thus satisfying the downward pressing of the pin 12 and ensuring that pins 12 at different heights are pressed to the same height by the pressing mechanism 6. The pressure head 64 and the lifting frame can slide relative to each other, forming a floating mechanism. Even if the exposed height of the pins 12 after insertion into the housing 11 is inconsistent, the pressure head 64 can compensate for the height difference through automatic retraction, ensuring that the final pressing force on each pin 12 is completely consistent.

[0045] The first lifting frame 62 includes a limiting part 621. When the pressure head 64 is not in contact with the pin 12, the lower surface of the middle part of the pressure head 64 abuts against the upper surface of the limiting part 621 to limit the height position of the pressure head 64 and prevent the pressure head 64 from detaching from the first lifting frame 62 due to its own weight.

[0046] A first guide rail 65 is fixed on the first lifting frame 62, and a first slider that slides along the first guide rail 65 is fixed on the pressure head 64. The first guide rail 65 and the first slider cooperate to ensure that the pressure head 64 can only move in the vertical direction, ensuring that the force applied by the pressure head 64 to the pin 12 is always downward, reducing damage to the pin 12 caused by deviation in the direction of force application. To further prevent the pressure head 64 from falling, a first anti-fall rod 66 is also fixed on the first lifting frame 62, located below the first slider. When the pressure head 64 and the limiting part 621 abut, the first slider and the first anti-fall rod 66 abut against each other to limit the downward movement of the first slider, further preventing the pressure head 64 from falling off the first lifting frame 62.

[0047] See appendix Figure 11 As shown, the connecting assembly 51 includes a first conveying section 511, a second conveying section 512, a welding machine 513, a punching machine 514, and a fourth robot arm 515. The first conveying section 511 and the second conveying section 512 are vertically distributed. The first conveying section 511 is used to convey the pins 12, and the pins 12 conveyed by the first conveying section 511 are fixed on the material belt. The second conveying section 512 is used to convey the cable 13. The welding machine 513 is used to weld the cable 13 and the pins 12 to be fixed. The punching machine 514 is used to cut the pins 12 that have been welded to the cable 13 from the material belt. The fourth robot arm 515 is used to transport the single pins 12 cut by the punching machine 514 to the working area of ​​the third robot arm 52.

[0048] The structure of the first conveying unit 511 is not limited, as long as it can convey the material belt. For example, the first conveying unit 511 includes a driving wheel and a driven wheel spaced apart vertically. The material belt passes between the driving wheel and the driven wheel and moves when the driving wheel rotates.

[0049] See appendix Figure 12 and attached Figure 13 As shown, the structure of the second conveying unit 512 is not limited, as long as it can convey the cable 13. For example, the second conveying unit 512 includes two clamping plates 5121 that can move closer and further away in the vertical direction. The cable 13 can be clamped between the two clamping plates 5121. The two clamping plates 5121 can clamp and release the cable 13 under the drive of the clamping drive member 5124. The clamping drive member 5124 moves closer or further away from the first conveying unit 511 synchronously under the drive of the linear module 5122. After clamping the cable 13, the two clamping plates 5121 move towards the first conveying unit 511 until the end of the cable 13 and the pin 12 on the first conveying unit 511 coincide in the vertical direction. After the cable 13 and the pin 12 are welded, the two clamping plates 5121 release the cable 13 and move away from the first conveying unit 511 to reset. After resetting, the cable 13 is clamped and conveyed again. The second conveying section 512 also includes a guide plate 5123. The cable 13 passes through the guide plate 5123. The guide plate 5123 is located between the clamping plate 5121 and the first conveying section 511 and is connected to a linear module 5122 together with the clamping plate 5121. The guide plate 5123 moves closer to or further away from the first conveying section 511 synchronously with the clamping plate 5121 and guides the cable 13 to ensure that the cable 13 remains straight. The guide plate 5123 only guides the cable 13 and does not clamp the cable 13.

[0050] A cutter 516 is provided at the connection between the first conveying section 511 and the second conveying section 512. The cutter 516 is used to cut the cable 13 after it has been soldered to the pin 12 and other cables 13. The cutter 516 includes an upper cutter and a lower cutter distributed in the vertical direction. The upper cutter and the lower cutter move closer or further apart in the vertical direction under the drive of the cutter drive member. When the upper cutter and the lower cutter move away from each other, a channel is formed between them for the guide plate 5123 to pass through. At this time, the clamping plate 5121 conveys the clamped cable 13 to partially overlap with the pin 12. When the two clamping plates 5121 release the cable 13 and return to their original position away from the first conveying section 511, the cutter 516 is located between the clamping plate 5121 and the first conveying section 511, and the upper cutter and the lower cutter move closer to each other to cut the cable 13.

[0051] The welding machine 513 includes a welding head that can move up and down. The welding head is located directly above the overlapping area of ​​the pin 12 and the cable 13 on the first conveyor section 511. When the second conveyor section 512 conveys part of the cable 13 until it overlaps with the pin 12 on the first conveyor section 511, the welding head moves down to complete the welding. The pin 12, after being welded to the cable 13, is still on the material strip and is conveyed by the first conveyor section 511 to the punching machine 514. The punching machine 514 can be a pneumatic punching machine, a punching shearing machine, etc., to separate the pin 12 from the material strip.

[0052] The assembly device also includes a welding mechanism located behind the pressing mechanism 6 in the rotation direction of the turntable 2. The welding mechanism is used to weld the pin 12 inserted into the housing 11 to the welding area of ​​the housing 11.

[0053] The present invention also discloses a method for assembling the housing 11 and pin 12 for the reversing radar 1. Based on the above-mentioned assembly device, the assembly method includes: The carrier 3 moves to the position of the first pressing assembly 43a. The first pressing assembly 43a presses the pressure plate 331 on the carrier 3 to release the housing 11 in the second placement cavity 312. The first handling robot places a housing 11 into the first placement cavity 311 of the carrier 3 and removes the housing 11 from the second placement cavity 312.

[0054] Turntable 2 drives carrier 3 to the position of second pressing component 43b. The second pressing component 43b presses the pressure plate 331 on carrier 3 to release the obstruction of the second placement cavity 312. The second handling robot moves the housing 11 in the first placement cavity 311 into the second placement cavity 312.

[0055] The turntable 2 drives the carrier 3 to the pin insertion mechanism 5. After the carrier 3 leaves the second pressing assembly 43b, the pressure plate 331, driven by the second elastic element 332, presses down on the housing 11 in the second placement cavity 312. The pin insertion mechanism 5 is used to insert the pins 12, which are soldered to the cable 13, into the housing 11 of the second placement cavity 312.

[0056] The turntable 2 drives the carrier 3 to the pressing mechanism 6, which is used to press the pin 12 inserted into the housing 11 into place and to issue an alarm when the pin 12 is not pressed into place.

[0057] Turntable 2 drives carrier 3 to the welding mechanism, which is used to weld the pin 12 and the welding area inside the housing 11.

[0058] Turntable 2 drives carrier 3 to the position of the first pressing component 43a, and repeats the above process to complete the assembly of housing 11 and pin 12.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention.
