Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and in particular to automatic cable welding and sleeve heat shrinking equipment. Background Technology

[0002] In industrial applications, there are frequent operations requiring the soldering of two different types of twin-stranded cables to twin-stranded or multi-stranded cables. (See appendix.) Figure 1 As shown, the fusion of two-strand cables with two-strand or multi-strand cables refers to the welding of two types of cables, where the first cable has two strands and the second cable also has two strands, or the second cable has multiple strands. Therefore, during welding, both the first and second cables are first divided into Y-shaped structures. At this point, both the first and second cables include a first bundle, a second bundle, and a twisted portion of the first and second bundles. The first bundle of the first cable is then welded to the first bundle of the second cable, and the second bundle of the first cable is welded to the second bundle of the second cable. A sleeve is pre-installed on both the first and second bundles. After welding, the sleeve needs to be moved to the welding joint of the cable and heat-shrinked. For this type of double welding point of two-strand or multi-strand cables, how to achieve rapid welding and sleeve heat shrinking at the two welding points becomes a technical problem that needs to be solved. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an automatic cable welding and sleeve heat shrinking device that can realize the welding of cables with double welding points and the heat shrinking of sleeves. In particular, it can move the sleeve to a designated position before heat shrinking to ensure the quality of heat shrinking.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic cable welding and sheath heat shrinking device, comprising: A feeding device, comprising a conveying mechanism and a clamp connected to the conveying mechanism, the clamp being used to clamp a first cable and a second cable arranged side by side along a first direction, the clamp moving between a feeding position and a discharging position under the conveying of the conveying mechanism; A welding device, located on one side of the feeding device in a first direction and including a welding table for welding; A first tube-pulling device is located in a first direction on the side of the welding device away from the feeding device. The first tube-pulling device includes a clamping mechanism, a separating mechanism, and a pulling mechanism. The clamping mechanism clamps the welded first cable and second cable. The separating mechanism separates the first bundle portion of the first cable and second cable from the second bundle portion of the first cable and second cable. The pulling mechanism pulls the sleeve pre-fitted on the first bundle portion or the second bundle portion. The pulling mechanism can switch the pulling direction, and the pulling direction is consistent with the setting direction of the first bundle portion and the second bundle portion, respectively. A conveying device for conveying the first cable and the second cable between the unloading position and the welding device, and between the welding device and the first tube-pulling device. The beneficial effects of this utility model are as follows: Automatic feeding is achieved through a feeding device, and the first and second cables are automatically transported between the feeding device and the welding device, and between the welding device and the first tube-pulling device, through a conveying device, thereby realizing automatic welding of the cables and heat shrinking of the sleeve.

[0005] The first tube-pulling device sets the pulling direction to be the same for both the first and second bundles, thus enabling the pulling of both sleeves and providing a structural basis for realizing the welding of bidirectional cables after welding and the automatic heat shrinking of heat shrink sleeves.

[0006] Furthermore, the actuating mechanism includes a fixed plate, a connecting plate, an actuating gripper, and a tangential portion. The connecting plate is pivotally connected to the fixed plate and can swing relative to the fixed plate under the push of the tangential portion. The actuating gripper can reciprocate along the length direction of the connecting plate. The swinging of the connecting plate changes the actuating path of the actuating gripper, thereby actuating the sleeve on the first and second bundles in different extension directions. Furthermore, the tangential portion includes a linear actuator pivotally connected to the fixed plate, with the output end of the linear actuator pivotally connected to the end of the connecting plate. The linear actuator is used to quickly switch the angle of the connecting plate, thereby changing the actuation path of the gripper.

[0007] Furthermore, the clamping mechanism includes two clamping jaws located on both sides of the separating mechanism in the second direction, and a first elastic element and a clamping pusher corresponding to each clamping jaw. The two clamping jaws respectively clamp the twisted portions of the first cable and the second cable. The first elastic element always provides a force to the corresponding clamping jaw in the second direction to move it taut, thus tightening the first cable or the second cable. The clamping pusher can push the corresponding clamping jaw to move against the elastic force of the first elastic element. The first elastic element can prevent the cable from loosening and bending, which would hinder the sleeve from being pushed along the cable to the target position and affect the heat shrinking effect.

[0008] Furthermore, the device also includes a heat shrink device located in a first direction on the side of the first tube-pulling device away from the welding device; The first tube-pulling device also includes a first lateral movement mechanism. The clamping mechanism is connected to the first lateral movement mechanism and moves along a first direction under the drive of the first lateral movement mechanism. The clamping mechanism clamps the first cable and the second cable after tube pulling and transports them into the heat shrinking device.

[0009] Furthermore, the first cable-pulling device also includes a clamping part located below the actuation mechanism. This clamping part can move up and down to clamp the twisted portion of the first or second cable near the first bundle. The cable-pulling design creates a fixed point at the clamping part, thus preventing the first and second cables from being excessively spread at the clamping part location under the action of the spacing mechanism, which would affect the opening direction of the first and second bundles and prevent them from cooperating with the actuation direction of the pre-set angle actuation mechanism. Therefore, by setting the clamping part, a better structural fit can be achieved with the actuation mechanism, and the structure of the actuation mechanism is simplified to the greatest extent.

[0010] Furthermore, the separating mechanism includes a vertically movable support claw that can enter from below between the first bundle and the second bundle and separate the first bundle and the second bundle. Furthermore, the equipment also includes a second tube-shifting device located between the loading position and the unloading position. The second tube-shifting device includes a shifting plate located above the conveying mechanism and movable in a second direction and a vertical direction. The shifting plate has a V-shaped groove and can shift the sleeve away from the clamping mechanism. Before welding, the sleeve is shifted to a position away from the welding point to prevent the sleeve from melting during welding, which would affect the processing effect.

[0011] Furthermore, the conveying device includes a first conveying component and a second conveying component capable of synchronously moving along a first direction and a second direction. Each of the first and second conveying components includes a first conveying jaw, a second conveying jaw, and a third conveying jaw for gripping the first bundle, the second bundle, and the twisted portion, respectively. The first conveying jaw of the first conveying component and the first conveying jaw of the second conveying component move up and down synchronously, with the ends of the two first bundles located between the two first conveying jaws. Similarly, the second conveying jaw of the first conveying component and the second conveying jaw of the second conveying component move up and down synchronously, with the ends of the two second bundles located between the two second conveying jaws. The conveying device can synchronously convey the first cable and the second cable, and sequentially place the two points to be soldered onto the soldering device.

[0012] Furthermore, the first and corresponding second transport grippers are staggered in the second direction, and the distance between the two first and second transport grippers in the first direction is the same as the distance between the two second transport grippers in the first direction, which is greater than the width of the welding station in the first direction. This staggered arrangement makes efficient use of space, allowing the first and corresponding second transport grippers to open synchronously. Attached Figure Description

[0015] In the diagrams below, X is the second direction, Y is the first direction, and Z is the vertical direction.

[0016] This utility model discloses an automatic cable welding and tubing heat shrinking device, used for welding cables and heat shrinking the tubing 13 at the welding point. See appendix. Figure 1 As shown, the cable includes a first cable 11 and a second cable 12. Both the first cable 11 and the second cable 12 include a first bundle 1a, a second bundle 1b, and a twisted portion formed by winding the first bundle 1a and the second bundle 1b together. The first bundle 1a, the second bundle 1b, and the twisted portion form a Y-shaped structure, requiring the first bundle 1a of the first cable 11 and the first bundle 1a and the second bundle 1b of the second cable 12 to be soldered. A sleeve 13 is also fitted onto the first bundle 1a and the second bundle 1b of the first cable 11 or the second cable 12, respectively. After soldering, the sleeve 13 is pushed to the solder joint for heat shrinking.

[0017] See appendix Figure 2 As shown, the equipment includes a feeding device 2, a welding device 3, a first tube-pulling device 4, a heat-shrinking device 5, and a conveying device 6. The feeding device 2, welding device 3, first tube-pulling device 4, and heat-shrinking device 5 are arranged sequentially along a first direction. The conveying device 6 is used to convey the first cable 11 and the second cable 12 between the unloading position and the welding device 3, and between the welding device 3 and the first tube-pulling device 4.

[0018] Participate in the attached Figure 13 As shown, the feeding device 2 includes a conveying mechanism 21 and a clamp 22 connected to the conveying mechanism 21. The clamp 22 is used to clamp a first cable 11 and a second cable 12 that are arranged side by side along a second direction. The clamp 22 moves between a feeding position and a discharging position under the conveying of the conveying mechanism 21. The first cable 11 and the second cable 12 are placed on the clamp 22 at the feeding position, and the conveying device 6 transports the first cable 11 and the second cable 12 at the discharging position.

[0019] The welding apparatus 3 includes a welding table for welding. The welding apparatus 3 is an ultrasonic welding machine used to weld the overlapping parts of the two first beams 1a and the overlapping parts of the two second beams 1b.

[0020] Because the sleeve 13 is located on one side of the welding point during welding, the first sleeve-pulling device 4 is used to move the sleeve 13 to the welding point, which facilitates subsequent heat shrinking. See appendix. Figure 3As shown, the first tube-pulling device 4 includes a clamping mechanism 41, a separating mechanism 42, and a pulling mechanism 43. The clamping mechanism 41 clamps the welded first cable 11 and second cable 12. The separating mechanism 42 is used to separate the first bundle 1a of the first cable 11 and the second bundle 1b of the second cable 12. The pulling mechanism 43 is used to pull the sleeve 13 pre-fitted on the first bundle 1a or the second bundle 1b. The pulling mechanism 43 can switch the pulling direction, and the pulling direction is consistent with the setting direction of the first bundle 1a and the second bundle 1b, respectively.

[0021] In this embodiment, automatic feeding is achieved by the feeding device 2, and the first cable 11 and the second cable 12 are automatically transported between the feeding device 2 and the welding device 3, and between the welding device 3 and the first tube-pulling device 4 by the transport device 6, so as to achieve automatic welding of the cables and heat shrinking of the sleeve 13.

[0022] After the first bundle 1a and the second bundle 1b of the first cable 11 and the second cable 12 are welded respectively, in order to avoid interference with the heat shrinkage of the two sleeves 13, it is necessary to separate the two sleeves 13. This is because the separating mechanism 42 is needed to separate the first bundle 1a and the second bundle 1b of the two sleeves 13 and form a certain included angle. At this time, if the turning direction of the turning mechanism 43 is unidirectional, it will not be able to meet the turning requirements of the two sleeves 13, or the included angle formed between the turning direction and the cable will cause damage to the cable during turning. Therefore, the first sleeve turning device 4 sets the turning direction to be the same for both the first bundle 1a and the second bundle 1b, thus meeting the turning requirements of the two sleeves 13, and providing a structural basis for realizing the welding of bidirectional cables after welding and the automatic heat shrinkage of the heat shrinkable sleeves 13.

[0023] See appendix Figure 4 and attached Figure 5 As shown, the actuating mechanism 43 includes a fixed plate 431, a connecting plate 432, an actuating gripper 433, and a tangential portion 434. The fixed plate 431 is fixed, and the connecting plate 432 is pivotally connected to the fixed plate 431 and can swing relative to the fixed plate 431 under the push of the tangential portion 434. Figure 5 (In the direction of the arrow in the image), the gripper 433 can be moved back and forth along the length of the connecting plate 432 by moving the gripper 433. After the first cable 11 and the second cable 12 are clamped by the clamping mechanism 41 after welding, they are moved to a position approximately below the actuating mechanism 43. The actuating claw 433 and the connecting plate 432 are then turned by the tangential part 434 so that the length direction of the connecting plate 432 is parallel to the first bundle 1a and the second bundle 1b. The actuating claw 433 moves along the length direction on the connecting plate 432 to actuate the sleeve 13.

[0024] The connecting plate 432 and the fixed plate 431 are parallel and extend horizontally. The connecting plate 432 is located below the fixed plate 431, and the actuating gripper 433 is located below the connecting plate 432. The connecting plate 432 is pivotally connected to the fixed plate 431 via a pivot shaft 4321. The connecting plate 432 can swing around the pivot shaft 4321 in the horizontal plane until the length direction of the connecting plate 432 is consistent with the movement direction of the sleeve 13.

[0025] The connecting plate 432 is provided with a toggle drive unit 435 that drives the toggle gripper 433 to move along its own length. The toggle drive unit 435 is a linear module used to drive the toggle gripper 433 to perform linear reciprocating movement. For example, the toggle drive unit 435 consists of a rotary drive component, pulleys, and a transmission belt. The first rotary drive component is fixed to the connecting plate 432. Two pulleys are rotatably connected to the connecting plate 432, one of which is connected to the output end of the rotary drive component and rotates under its drive. The transmission belt is wound around the two pulleys. The toggle gripper 433 is connected to the linear portion of the transmission belt. When the transmission belt rotates, the toggle gripper 433 can move along a straight line. The toggle gripper 433 includes a gripper cylinder and a gripper body. The toggle gripper 433 can clamp the sleeve 13 and push the sleeve 13 to move synchronously during movement.

[0026] The actuating gripper 433 can also move vertically to get closer to or away from the sleeve 13, allowing the first cable 11 and the second cable 12 below to pass through. Therefore, the actuating mechanism 43 also includes an actuating lifting member 436, which is fixedly connected to the transmission belt and whose output end is fixedly connected to the actuating gripper 433. The actuating lifting member 436 swings and moves synchronously with the actuating gripper 433 and can drive the actuating gripper 433 to rise and fall.

[0027] See appendix Figure 4 As shown, the tangential portion 434 includes a linear actuator pivotally connected to the fixed plate 431. The output end of the linear actuator is pivotally connected to the end of the connecting plate 432. For example, the linear actuator is a cylinder, with the cylinder housing hinged to the fixed plate 431. The end of the cylinder's piston rod is pivotally connected to the end of the connecting plate 432 via a connecting shaft 4322. When the piston rod extends and retracts, it pushes the connecting plate 432 to swing around the pivot shaft 4321.

[0028] To save space, the linear drive unit is fixed on the upper surface of the fixed plate 431. At this time, the connecting shaft 4322 passes through the fixed plate 431. The fixed plate 431 is also provided with an arc-shaped guide groove 4311. The guide groove 4311 makes way for the swing of the connecting shaft 4322 on the one hand, and guides the movement of the connecting shaft 4322 in the other direction.

[0029] See appendix Figure 6 and attached Figure 7As shown, the clamping mechanism 41 includes two clamping jaws 411 located on both sides of the separating mechanism 42 in the second direction, and a first elastic member 412 and a clamping pusher 413 corresponding to each clamping jaw 411. The two clamping jaws 411 respectively clamp the twisted portion of the first cable 11 and the second cable 12. The first elastic member 412 always provides a force to the corresponding clamping jaw 411 to move in the second direction to tighten the first cable 11 or the second cable 12. The clamping pusher 413 can push the corresponding clamping jaw 411 to move against the elastic force of the first elastic member 412.

[0030] After the clamping mechanism 41 clamps the first cable 11 and the second cable 12 after welding, the actuating mechanism 43 actuates the sleeve 13. At this time, the cables need to be kept taut so that the sleeve 13 can slide easily. Therefore, compared with the clamping mechanism 41 which only has clamping claws 411, the clamping mechanism 41 in this application adds a first elastic element 412. The first elastic element 412 will pull the two clamping claws 411 away from each other, tightening the first cable 11 and the second cable 12 after welding. The elastic force of the first elastic element 412 does not need to be too large, it is only necessary to tighten the first cable 11 and the second cable 12, and it should not break the first cable 11 and the second cable 12.

[0031] For example, the first elastic element 412 is a tension spring, and the clamping jaw 411 slides along the connecting seat. One end of the tension spring is connected to the connecting seat, and the other end is fixed to the clamping jaw 411. When the conveying device 6 conveys the welded first cable 11 and second cable 12 to the working area of ​​the clamping mechanism 41, the clamping pusher 413 pushes the corresponding clamping jaw 411 closer to each other. During this process, the tension spring is continuously stretched. When the clamping jaw 411 clamps the cable, the clamping pusher 413 resets and no longer applies the force in the first direction to the clamping jaw 411. At this time, the tension spring pulls the corresponding clamping jaw 411 back to its original position, and the two clamping jaws 411 move away from each other, tightening the welded first cable 11 and second cable 12, which facilitates the subsequent movement of the sleeve 13 by the first tube-pulling device 4.

[0032] The first tube-pulling device 4 also includes a first lateral movement mechanism 44. A clamping mechanism 41 is connected to the first lateral movement mechanism 44 and moves along a first direction under the drive of the first lateral movement mechanism 44. The clamping mechanism 41 clamps the first cable 11 and the second cable 12 after tube pulling and conveys them into the heat-shrinking device 5. After the pulling structure completes tube pulling, the sleeve 13 is located at the welding point, and the sleeve 13 and the heat-shrinking device 5 are aligned. At this time, the support claws of the separating mechanism 42 move downwards and no longer insert between the first bundle 1a and the second bundle 1b. During this process, the clamping mechanism 41 always clamps the first cable 11 and the second cable 12, and the distance between the two clamping claws 411 is greater than the width of the heat-shrinking device 5. When the clamping mechanism 41 moves along the first direction, it can convey portions of the first cable 11 and the second cable 12, along with the sleeve 13 on them, into the heat-shrinking device 5. After the clamping mechanism 41 releases the first cable 11 and the second cable 12, the first cable 11 and the second cable 12 are conveyed in the conveying device for sleeve 13 heat shrinking.

[0033] The first transverse mechanism 44 is a linear module. In one embodiment, the first transverse mechanism 44 and the toggle drive unit 435 have the same structure. Of course, it can also be a linear module with other structures.

[0034] See appendix Figure 6 As shown, the separating mechanism 42 is located between two clamping jaws 411. The separating mechanism 42 includes a separating support jaw 421 that can move up and down. The separating support jaw 421 can enter from below between the first bundle 1a and the second bundle 1b and separate the first bundle 1a and the second bundle 1b. Initially, the height of the separating support jaw is lower than the height of the first cable 11 and the second cable 12 held by the clamping sub-mechanism. When the clamping mechanism 41 reaches the position of the separating support jaw 421, the separating support jaw 421 moves upward and enters from below between the first bundle 1a and the second bundle 1b to separate the first bundle 1a and the second bundle 1b. Therefore, the separating mechanism 42 also includes a separating lifting drive member 422 that drives the separating support jaw 421 to move up and down. The separating support jaw 421 and the separating lifting drive member 422 are connected.

[0035] In one embodiment, the first tube-pulling device 4 further includes a clamping part 45 located below the actuation mechanism 43. The clamping part 45 can move up and down and clamp the twisted portion of the first cable 11 or the second cable 12 near the first bundle portion 1a.

[0036] Under the action of the separating mechanism 42, the first bundle 1a and the second bundle 1b form a large gap area. At this time, the twisted part may also be separated by the separating mechanism 42, which will affect the actuation of the sleeve 13 by the actuation mechanism 43. Therefore, a clamping part 45 is provided. The clamping part 45 can clamp the twisted part near the position of the first bundle 1a. The position of the clamping part 45 forms a fixed point for the multi-strand cable, preventing the twisted part from being opened by the separating mechanism. This would cause the direction of the first bundle 1a or the second bundle 1b, which is originally located below the actuation claw 433 of the actuation mechanism 43, to shift, thus affecting the actuation effect. By setting the clamping part 45 and coordinating the adjustment of the two different actuation directions of the actuation mechanism 43, the overall coordination effect of the actuation mechanism 43 can be improved, and it can also ensure that the direction of the actuation claw 433 is highly consistent with that of the first bundle 1a or the second bundle 1b after swinging to the target angle.

[0037] The heat shrinking device 5 includes a heat shrinking cavity, which contains a heating plate and a heat shrinking conveyor line. The sleeve 13 is moved to the welding point by the first tube-pulling device 4. After the first tube-pulling device 4 transports the welded first cable 11 and second cable 12 into the heat shrinking cavity, the cables can be transported by the heat shrinking conveyor line. During the transport process, the sleeve 13 completes heat shrinking.

[0038] When welding device 3 welds the first cable 11 and the second cable 12, sleeve 13 is already fitted onto the first bundle 1a and the second bundle 1b. However, during welding, sleeve 13 needs to avoid the welding platform. Therefore, the equipment also includes a second sleeve-pulling device 7. Before the first cable 11 and the second cable 12 reach the welding device 3, the second sleeve-pulling device 7 moves the sleeve 13 to one side of the welding point to avoid melting the sleeve 13 during welding.

[0039] See appendix Figure 2 and attached Figure 12 As shown, the second tube-pushing device 7 is located between the loading and unloading positions. The tube-pushing device includes a pushing plate 71 located above the conveying mechanism 21 and movable in the second direction and the vertical direction. The pushing plate 71 has a V-shaped groove and can push the sleeve 13 toward the side away from the clamp 22. The pushing plates 71 appear in pairs, and there are two pairs. One pair of pushing plates 71 are distributed at intervals along the second direction and are used to push the sleeve 13 on the first bundle 1a; the other pair of pushing plates are also distributed at intervals along the second direction and are used to push the sleeve 13 on the second bundle 1b.

[0040] The clamp 22 holds the first bundle 1a and the second bundle 1b. The areas to be welded in the first bundle 1a and the second bundle 1b are located within the clamp 22, while the sleeve 13 is located outside the clamp 22. However, at this time, the sleeve 13 may be close to the clamp 22, which means the sleeve 13 is close to the area to be welded and may be melted by the welding device 3. Therefore, the pair of actuating plates 71 initially move closer to each other, abutting against the two outer surfaces of the clamp 22 in the second direction. Then, the pair of actuating plates 71 move further apart, pushing the sleeve 13 away from the clamp 22, that is, away from the area to be welded.

[0041] The second tube-shifting device 7 also includes a tube-shifting horizontal movement mechanism 72 and a tube-shifting lifting mechanism 73. There are two tube-shifting lifting mechanisms 73, both of which are connected to the tube-shifting horizontal movement mechanism 72. The tube-shifting horizontal movement mechanism 72 can drive the two tube-shifting lifting mechanisms 73 to move relative to or away from each other. A pair of actuating plates 71 are respectively connected to the two tube-shifting lifting mechanisms 73.

[0042] See appendix Figure 8 As shown, the handling device 6 includes a first handling component 61 and a second handling component 62. The first handling component 61 and the second handling component 62 move synchronously along a first direction and a second direction under the drive of the cross drive mechanism 63.

[0043] See appendix Figure 9 and attached Figure 10 As shown, both the first transport assembly 61 and the second transport assembly 62 include a first transport gripper, a second transport gripper, and a third transport gripper for gripping the first bundle 1a, the second bundle 1b, and the twisted portion, respectively. The first transport gripper of the first transport assembly 61 and the first transport gripper of the second transport assembly 62 move up and down synchronously, with the ends of the two first bundles 1a located between the two first transport grippers. The second transport gripper of the first transport assembly 61 and the second transport gripper of the second transport assembly 62 move up and down synchronously, with the ends of the two second bundles 1b located between the two second transport grippers.

[0044] The first, second, and third grippers of the first transport assembly 61 are respectively first gripper 611, second gripper 612, and third gripper 613. The first, second, and third grippers of the second transport assembly 62 are respectively first gripper 621, second gripper 622, and third gripper 623. The first gripper 611 and the first gripper 621 move up and down synchronously, respectively gripping the first bundle 1a of the first cable 11 and the first bundle 1a of the second cable 12. The end portions of the two first bundles 1a overlap and are located between the first gripper 611 and the first gripper 621. The welding device 3 welds the overlapping portion of the first bundles 1a. The second gripper 612 and the second gripper 622 move up and down synchronously, respectively gripping the second bundle 1b of the first cable 11 and the second bundle 1b of the second cable 12. The ends of the two second bundles 1b overlap and are located between the second gripper 612 and the second gripper 622. The welding mechanism welds the overlapping portions of the second bundles 1b. The synchronous movement of the two first grippers and the separate movement of the two second grippers allow the two first bundles 1a and the two second bundles 1b to descend to the welding device 3 for welding.

[0045] The first gripper 611 and the second gripper 612 are fixed together at the output end of a lifting drive component 6111. The first gripper 621 and the second gripper 622 are fixed together at the output end of a lifting drive component 6121. The third gripper 613 and the third gripper 623 are respectively connected to the output ends of the lifting drive component 6131 and the lifting drive component 6231.

[0046] Because the spacing between the first bundle 1a of the first cable 11 and the first bundle 1a of the second cable 12 in the first direction is small, similarly, the spacing between the second bundle 1b of the first cable 11 and the second bundle 1b of the second cable 12 in the first direction is also small. Therefore, the spacing between the first gripper and the second gripper in the first direction is limited. In order for the first bundle 1a and the second bundle 1b to be gripped, in one embodiment, referring to the accompanying drawings, the first gripper 611 and the second gripper 612 are staggered in the first direction, that is, the first gripper 611 and the second gripper 612 are distributed at intervals along the first direction, but are arranged one behind the other in the second direction. Similarly, the first gripper 621 and the second gripper 622 are also staggered in the first direction. This staggered arrangement structure allows the first gripper and the second gripper to grip the first bundle 1a and the second bundle 1b respectively in a limited space, and the first gripper and the second gripper do not interfere with each other when they open synchronously.

[0047] The distance between the first jaw 611 and the second jaw 621 in the first direction is the same as the distance between the second jaw 612 and the second jaw 622 in the second direction, and is greater than the width of the welding table of the welding device 3 in the second direction. At this time, when welding is performed, the overlapping portion of the first bundle 1a between the first jaw 611 and the second jaw 621, and the overlapping portion of the second bundle 1b between the second jaw 612 and the second jaw 612, are located on opposite sides of the welding table in the second direction, ensuring that the first jaws and the second jaws do not interfere with the welding table.

[0048] After welding is completed by welding device 3, the welded area needs to be inspected. Therefore, please refer to the appendix. Figure 2 As shown, a visual inspection mechanism 8 is also provided between the welding device 3 and the first tube-pulling device 4. The transport mechanism will also transport the first cable 11 and the second cable 12 to the top of the visual inspection mechanism 8. The visual inspection mechanism 8 will take pictures of the welding joint of the first cable 11 and the second cable 12 for visual inspection.

[0049] To enable the visual inspection agency to take photos of the top and sides of the weld, see the appendix. Figure 10 and attached Figure 11 As shown, a first prism assembly 81 is disposed between the first jaw of the first transport assembly 61 and the first jaw of the second transport assembly 62, and the first prism assembly 81 is always higher than the first bundle portion 1a held by the first jaw. A second prism assembly 82 is disposed between the second jaw of the first transport assembly 61 and the second jaw of the second transport assembly 62, and the second prism assembly 82 is always higher than the second bundle portion 1b held by the second jaw.

[0050] The first prism assembly 81 and the second prism assembly 82 have an inverted V-shaped structure, which can reflect the images above and to the side of the welding part of the first beam 1a and the welding part of the second beam 1b.

[0051] In one embodiment, see Appendix Figure 2 As shown, a waste recycling box 9 is also provided between the visual inspection mechanism 8 and the welding device 3. When the welding point fails the inspection at the visual inspection mechanism 8, the conveying device 6 is reset. During the reset process, the first cable 11 and the second cable 12 are released, allowing the first cable 11 and the second cable 12 that failed the welding to fall into the waste recycling box 9. There is no need to perform subsequent tube removal. Even if the problem is found, the abnormal product is rejected.

[0052] See appendix Figure 13As shown, the clamp 22 includes two sets of clamp assemblies arranged along a first direction. One set of clamp assemblies is used to clamp the first bundle 1a of the first cable 11 and the second cable 12, and the other set of clamp assemblies is used to clamp the second bundle 1b of the first cable 11 and the second cable 12. The two sets of clamp assemblies have the same structure, but are staggered in the second direction to meet the space requirements between the first bundle 1a and the second bundle 1b.

[0053] Each clamp assembly 22 includes two clamping portions 221 distributed along a second direction, with the overlapping portions of the two first bundle portions 1a or the overlapping portions of the two second bundle portions 1b located between the two clamping portions 221. The two clamping portions 221 respectively clamp the first cable 11 and the second cable 12.

[0054] See appendix Figure 14 As shown, each clamping part 221 includes a guide seat 2211. The guide seat 2211 is provided with two clamping plates 2212 that can move relative to or away from each other, and a second elastic member 2213 corresponding to each clamping plate 2212. The second elastic member 2213 pushes the two clamping plates 2212 closer together to clamp a portion of the first bundle 1a or the second bundle 1b. When there is no external force, the second elastic member 2213, due to its own elasticity, causes the two clamping plates 2212 to move closer together to clamp the cable.

[0055] For example, the second elastic element 2213 is a spring, with one end fixed to the guide seat 2211 and the other end fixed to the corresponding clamping plate 2212. When there is no external force, the spring is in a natural or compressed state. When the two clamping plates 2212 move away from each other, the spring is continuously compressed, at which time the cable can enter and exit between the two clamping plates 2212.

[0056] The clamping part 221 also includes a lifting block 2214 that moves synchronously with it and can rise and fall relative to the guide seat 2211. The lifting block 2214 includes two symmetrically arranged inclined surfaces. When the lifting block 2214 moves upward, it can move between the two clamping plates 2212 and the inclined surfaces and clamping plates 2212 abut against each other. The lifting block 2214 uses the inclined surfaces to drive the two clamping plates 2212 away from each other when it moves upward.

[0057] To facilitate loading and unloading, the loading device 2 also includes unlocking mechanisms located at the loading and unloading positions. These unlocking mechanisms can drive the clamping plates 2212 to overcome the elastic force of the second elastic element 2213 and move away from each other. The unlocking mechanisms are located outside the conveying mechanism 21, meaning they do not move synchronously with the clamp 22. The unlocking mechanisms include unlocking drive components, which can abut against and drive the lifting block 2214 to move upward. When the unlocking drive components are reset, the lifting block 2214 moves downward and resets under the action of gravity. At this time, the clamping plates 2212 clamp the cable under the drive of the second elastic element 2213.

[0058] The conveying mechanism 21 is fixed with multiple clamps 22, which are spaced apart along the conveying direction of the conveying mechanism 21. The conveying mechanism 21 includes a closed-loop conveyor belt. During the rotation of the conveyor belt, the clamps 22 can cycle to the loading and unloading positions.

[0059] To facilitate the handling of the first cable 11 and the second cable 12 by the handling device 6, especially since the handling device 6 clamps the stranded portion, but the clamp 22 can only clamp the first bundle 1a and the second bundle 1b, the conveying device also includes a guiding mechanism 23 located at the discharge position. The guiding mechanism 23 is located outside the conveying mechanism 21 and includes a guide plate 231 and a guide gripper. The upper surface of the guide plate 231 is arc-shaped, and the stranded portion moves along the upper surface of the guide plate. The guide gripper is located in the middle position of the guide plate and can clamp the stranded portion to keep it in a horizontal state.

All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
