Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a welding device. Background Technology

[0002] Thermal relays have overload protection function. The current flowing into the thermal relay causes the bimetallic component in the thermal element to deform. When the deformation reaches a certain distance, it will trigger the main circuit to disconnect, thereby realizing the overload protection of the motor.

[0003] In related technologies, thermal element components include a terminal block, a bimetallic component, and a conductive rod. The welding between the terminal block and the bimetallic component, as well as the welding between the bimetallic component and the conductive rod, are usually completed manually. The welding efficiency and consistency are low, resulting in a high defect rate. Utility Model Content

The first driving component 246 is connected to the first linkage component 241 and is used to drive the first linkage component 241 to slide relative to the first bracket 210. For example, when the first welding device 200 is in operation, the first driving member 246 drives the first linkage member 241 to move downward, so that the first limiting plate 2411 pushes the first upper slider 221 downward through the first elastic member 243, and causes the first linkage plate 2412 to drive the first connecting rod 244 to rotate through the first cylindrical member 2441. The first connecting rod 244 pushes the first sliding member 245 to translate through the second cylindrical member 2443, and the first linkage surface 2452 pushes the third cylindrical member 233 to move upward, that is, drives the first lower slider 231 to move upward, thereby realizing the clamping of the first upper welding head 222 and the first lower welding head 232 on the bimetallic member 12 and the terminal block 11, which is stable, reliable and compact.

[0101] For example, the first elastic element 243 can be a spring.

[0102] For example, the first drive member 246 may be configured as a telescopic drive member, such as a linear cylinder.

[0103] For example, the first cylindrical member 2441, the second cylindrical member 2443 and the third cylindrical member 233 can all be configured as rolling structures such as rollers and bearings.

[0104] In one feasible implementation, the first linkage surface 2452 has a first surface, a second surface, and a third surface connected in sequence, with the first and third surfaces arranged in parallel and the second surface being an inclined surface. When the third cylindrical member 233 abuts against the first surface, the first lower welding head 232 separates from the bimetallic member 12 and makes way for the first carrier 110; when the third cylindrical member 233 abuts against the third surface, the first lower welding head 232 and the first upper welding head 222 clamp the bimetallic member 12 and the terminal block 11.

[0105] In one feasible embodiment, the first welding device 200 further includes a pre-compression elastic element 223 disposed on the first upper slider 221. In this embodiment, the bimetallic component 12 is located above the terminal block 11. During the process of the first driving assembly driving the first upper slider 221 to move downward, the pre-compression elastic element 223 first abuts against the bimetallic component 12, and then the first upper welding head 222 abuts against the bimetallic component 12. This effectively prevents the bimetallic component 12 and the terminal block 11 from shifting or lifting due to impact when the first upper welding head 222 and the first lower welding head 232 clamp the bimetallic component 12 and the terminal block 11, effectively ensuring the welding stability of the first welding device 200. It can be understood that the first lower welding head 232 abuts against the terminal block 11 to clamp the bimetallic component 12 and the terminal block 11 with the first upper welding head 222.

[0106] For example, the preload elastic element 223 can be configured as a telescopic spring locating pin or a rectangular spring.

[0107] In this embodiment, reference is made to Figure 4 As shown, the second welding device 500 includes a second support 510, a second upper welding assembly, a second lower welding assembly, and a second driving assembly. The second upper welding assembly includes a second upper slider 521 slidably connected to the second support 510 and a second upper welding head 522 disposed on the second upper slider 521. The second lower welding assembly includes a second lower slider 531 slidably connected to the second support 510 and a second lower welding head 532 disposed on the second lower slider 531. The second driving assembly is connected to both the second upper slider 521 and the second lower slider 531, and is used to drive the second upper welding head 522 and the second lower welding head 532 to clamp the bimetallic part 12 and the conductive rod 20 of the semi-finished product 10 on the second carrier 310, thereby welding the bimetallic part 12 and the conductive rod 20 together. In this embodiment, the second welding device 500 completes the welding operation through the drive of a second driving assembly, which is stable and reliable. It is understandable that the conductive rod 20 overlaps with the bimetallic part 12 of the semi-finished product 10 after the position is adjusted in the vertical direction, that is, the second upper welding head 522 and the second lower welding head 532 clamp the overlapping part of the bimetallic part 12 and the conductive rod 20 in the vertical direction, which effectively ensures the welding stability of the second welding device 500.

[0108] In one feasible embodiment, the second driving assembly includes a second linkage member 541, a second T-shaped rod 542, a second elastic member 543, a second sliding member 545, and a second driving member 546. The second linkage member 541 is slidably connected to the second bracket 510. The second linkage member 541 is provided with a second limiting plate 5411 and a second linkage plate 5412, and the second linkage plate 5412 is provided with a second guide hole. The rod portion of the second T-shaped rod 542 is fixedly connected to the second limiting plate 5411. The second upper slider 521 is provided with a second T-shaped groove 5211, and the T-shaped head of the second T-shaped rod 542 is inserted into the second T-shaped groove 5211. One end of the second elastic member 543 abuts against the second limiting plate 5411, and the other end abuts against the second upper slider 521. The second connecting rod 544 is provided with a fourth cylindrical member 5441, a second shaft 5442, and a fifth cylindrical member 546 in sequence along its extension direction. 443, the fourth cylindrical member 5441 is inserted into the second guide hole; the second sliding member 545 is slidably connected to the second bracket 510, the second sliding member 545 is located on the side of the second lower slider 531 away from the second upper slider 521, the second sliding member 545 is provided with a second linkage groove 5451 and a second linkage surface 5452, the fifth cylindrical member 5443 is inserted into the second linkage groove 5451, the second lower slider 531 is provided with a sixth cylindrical member 533, the sixth cylindrical member 533 abuts against the second linkage surface 5452; the second driving member 546 is connected to the second linkage member 541, the second driving member 546 is used to drive the second linkage member 541 to slide relative to the second bracket 510. For example, when the second welding device 500 is in operation, the second driving member 546 drives the second linkage member 541 to move downward, so that the second limiting plate 5411 pushes the second upper slider 521 downward through the second elastic member 543, and causes the second linkage plate 5412 to drive the second connecting rod 544 to rotate through the fourth cylindrical member 5441. The second connecting rod 544 pushes the second sliding member 545 to translate through the fifth cylindrical member 5443, and the second linkage surface 5452 pushes the sixth cylindrical member 533 to move upward, that is, drives the second lower slider 531 to move upward, thereby realizing the clamping of the second upper welding head 522 and the second lower welding head 532 on the bimetallic member 12 and the conductive rod 20, which is stable, reliable and compact.

[0109] For example, the second elastic element 543 may be a spring.

[0110] For example, the second drive member 546 may be a telescopic drive member, such as a linear cylinder.

[0111] For example, the fourth cylindrical member 5441, the fifth cylindrical member 5443 and the sixth cylindrical member 533 can all be configured as rolling structures such as rollers and bearings.

[0112] For example, the second linkage surface 5452 has the same shape as the first linkage surface 2452, which will not be described in detail in this embodiment.

[0113] In this embodiment, reference is made to Figures 5 to 7 As shown, the first transfer mechanism 410 includes a transfer drive assembly and a transfer gripping assembly disposed on the transfer drive assembly. The transfer gripping assembly includes a first transfer gripper 413 and a second transfer gripper 414. The transfer drive assembly is used to drive the transfer gripping assembly to move between a first position and a second position. The second transfer mechanism 420 includes a first transfer rotation drive member 421 and a third transfer gripper 422 disposed on the first transfer rotation drive member 421. The first transfer rotation drive member 421 is used to drive the third transfer gripper 422 to rotate. When the transfer gripping component moves to the first position, the first transfer gripper 413 can grip the semi-finished product 10 on the first carrier 110, and the second transfer gripper 414 can grip the semi-finished product 10 on the third transfer gripper 422; when the transfer gripping component moves to the second position, the third transfer gripper 422 can grip the semi-finished product 10 on the first transfer gripper 413, and the second transfer gripper 414 can place the gripped semi-finished product 10 on the second carrier 310. For example, after the first transfer rotation drive 421 drives the third transfer gripper 422 to rotate to adjust the position of the semi-finished product 10, firstly, the first transfer gripper 413 is controlled to grab the semi-finished product 10 on the first carrier 110, and the second transfer gripper 414 grabs the semi-finished product 10 on the third transfer gripper 422; secondly, the transfer drive assembly is controlled to drive the transfer gripping assembly to move from the first position to the second position, and the first transfer rotation drive 421 is controlled to drive the third transfer gripper 422 to rotate and reset; then, the third transfer gripper 422 is controlled to grab the semi-finished product 10 on the first transfer gripper 413, and the second transfer gripper 414 places the grabbed semi-finished product 10 on the second carrier 310; finally, the transfer drive assembly is controlled to drive the transfer gripping assembly to reset from the second position to the first position, and the first transfer rotation drive 421 is controlled to drive the third transfer gripper 422 to rotate to adjust the position of the semi-finished product 10. Understandably, the first transfer rotary drive 421 drives the third transfer gripper 422 to adjust the position and reset of the semi-finished product 10, which is completed during the transfer of the semi-finished product 10, effectively improving the operating cycle of the transfer device 400 and increasing work efficiency. Specifically, the first transfer rotary drive 421 drives the third transfer gripper 422 to rotate the semi-finished product 10 around a horizontal direction.

[0114] For example, the first transfer gripper 413, the second transfer gripper 414 and the third transfer gripper 422 can all be configured as gripper structures driven by finger cylinders.

[0115] For example, the first intermediate rotary drive 421 can be configured as a rotary cylinder or a motor reducer module.

[0116] In one feasible implementation, the transfer drive assembly includes a first transfer translation drive 411 and a first transfer vertical drive 412 disposed on the first transfer translation drive 411. The transfer gripping assembly is disposed on the first transfer vertical drive 412. The first transfer translation drive 411 is used to drive the transfer gripping assembly to move horizontally, and the first transfer vertical drive 412 is used to drive the transfer gripping assembly to move vertically. Understandably, the first transfer translation drive 411 drives the transfer gripping assembly to move between the first position and the second position, and the first transfer vertical drive 412 drives the transfer gripping assembly to move upward to prevent the semi-finished product 10 from interfering with the first carrier 110 when transferred under the grip of the first transfer claw 413, and to prevent the semi-finished product 10 from interfering with the second carrier 310 when transferred under the grip of the second transfer claw 414; the first transfer vertical drive 412 drives the transfer gripping assembly to move downward, the first transfer claw 413 in the first position is suitable for gripping the semi-finished product 10 on the first carrier 110, the semi-finished product 10 in the first transfer claw 413 in the second position is suitable for being gripped by the third transfer claw 422, the second transfer claw 414 in the first position is suitable for gripping the semi-finished product 10 after the position adjustment on the third transfer claw 422, and the second transfer claw 414 in the second position is suitable for placing the semi-finished product 10 on the second carrier 310.

[0117] For example, the first transfer translation drive 411 can be configured as a slide module driven by a cylinder.

[0118] For example, the first intermediate vertical movement drive 412 can be configured as a slide module driven by a cylinder.

[0119] In one feasible implementation, a second transfer rotary drive 415 is provided on the first transfer vertical drive 412, and a second transfer gripper 414 is provided on the second transfer rotary drive 415. The second transfer rotary drive 415 is used to drive the second transfer gripper 414 to rotate, so as to readjust the position of the semi-finished product 10. After the semi-finished product 10 has been adjusted twice, the overlap between the bimetallic part 12 and the conductive rod 20 is located on the edge of the second carrier 310 away from the second turntable. This can make the structure of the second welding device 500 more compact and prevent the second welding device 500 from interfering with the second carrier 310 and the second turntable during operation. For example, the first transfer rotary drive 421 can drive the semi-finished product 10 to rotate 90° around the horizontal direction, and the second transfer rotary drive 415 can drive the semi-finished product 10 to rotate 180° around the vertical direction.

[0120] Understandably, when the control transfer drive component moves the transfer gripping component from the first position to the second position, the second transfer rotary drive component 415 drives the second transfer gripper 414 to adjust the position of the semi-finished product 10, effectively increasing the operating cycle of the transfer device 400 and improving work efficiency. Specifically, the second transfer rotary drive component 415 drives the second transfer gripper 414 to rotate the semi-finished product 10 in the vertical direction.

[0121] In some embodiments, the second transfer rotary drive 415 can be configured as a telescopic drive, such as a linear cylinder. The second transfer rotary drive 415 drives the second transfer gripper 414 to rotate via a first gear and rack structure (not shown), ensuring stable and reliable operation. Specifically, the first gear and rack structure includes a rotating seat rotatably mounted on the first transfer vertical drive 412, a first gear mounted on the rotating seat, and a first rack slidably mounted on the first transfer vertical drive 412. The second transfer rotary drive 415 is connected to the first rack, and the second transfer gripper 414 is mounted on the rotating seat. In this embodiment, the second transfer rotary drive 415 drives the first rack to slide, thereby driving the first gear to rotate via meshing transmission, and subsequently driving the second transfer gripper 414 to rotate via the rotating seat.

[0122] In other embodiments, the second intermediate rotary drive 415 may also be configured as a rotary cylinder or a motor reducer module.

[0123] In one feasible embodiment, the second transfer mechanism 420 further includes a second transfer translation drive 423, and the second transfer translation drive 423, the first transfer rotation drive 421, and the third transfer gripper 422 are connected in sequence. The second transfer translation drive 423 drives the third transfer gripper 422 to move horizontally, and the direction in which the first transfer translation drive 411 drives the transfer gripping assembly to move is perpendicular to the direction in which the second transfer translation drive 423 drives the third transfer gripper 422 to move. In this embodiment, the second transfer translation drive 423 drives the third transfer gripper 422 away from the first transfer mechanism 410 to prevent positional interference between the second transfer gripper 414 and the semi-finished product 10 on the third transfer gripper 422 during the movement of the second transfer gripper 414 from the second position to the first position; the second transfer translation drive 423 drives the third transfer gripper 422 closer to the first transfer mechanism 410 so that the second transfer gripper 414 at the first position is suitable for gripping the semi-finished product 10.

[0124] For example, the second transfer translation drive 423 can be configured as a telescopic drive, such as a linear cylinder.

[0125] In one feasible implementation, after the third transfer gripper 422 adjusts the position of the semi-finished product 10, there is a height difference between the position where the second transfer gripper 414 grasps the semi-finished product 10 and the position where the third transfer gripper 422 grasps the semi-finished product 10. To make the second transfer gripper 414, located in the first position, suitable for grasping the semi-finished product 10, the second transfer mechanism 420 further includes a second transfer vertical movement drive 424. The second transfer vertical movement drive 424 is disposed between the second transfer translation drive 423 and the first transfer rotation drive 421. The second transfer vertical movement drive 424 is used to drive the third transfer gripper 422 to move vertically. In this embodiment, the second transfer vertical movement drive 424 drives the third transfer gripper 422 to move downward, and the second transfer translation drive 423 drives the third transfer gripper 422 to move closer to the first transfer mechanism 410, so that the second transfer gripper 414, located in the first position, is suitable for grasping the semi-finished product 10.

[0126] For example, the second intermediate vertical movement drive 424 can be configured as a telescopic drive, such as a linear cylinder.

[0127] In this embodiment, reference is made to Figure 1 , Figure 5 , Figures 8 to 10 As shown, the first carrier 110 includes a first platform 111, a first clamping assembly, and a second clamping assembly. The first platform 111 is mounted on the first conveying device 100 and has a first placement slot 1111 and a second placement slot 1112. The first placement slot 1111 is used to place the connector 11, and the second placement slot 1112 is used to place the bimetallic strip 12, thereby achieving the positioning of the connector 11 and the bimetallic strip 12. The first clamping assembly includes a first clamping member 112 slidably connected to the first platform 111 and a first clamping elastic member 113 connected to the first clamping member 112. The first clamping elastic member 113 enables the first clamping member 112 to clamp the connector 11. The first placement groove 1111 is placed within the first placement groove 1111 to prevent the terminal block 11 from detaching from the first placement groove 1111; the second clamping assembly includes a second clamping member 114 slidably connected to the first platform 111 and a second clamping elastic member 115 connected to the second clamping member 114. The second clamping elastic member 115 enables the second clamping member 114 to clamp the bimetallic member 12 within the second placement groove 1112 to prevent the bimetallic member 12 from detaching from the second placement groove 1112, thereby ensuring the welding quality of the first welding device 200 welding the terminal block 11 and the bimetallic member 12 together.

[0128] For example, the first clamping elastic element 113 can be configured as a spring.

[0129] For example, the second clamping elastic element 115 can be a spring.

[0130] In one feasible embodiment, the welding equipment further includes a first clearance drive 120, which is correspondingly disposed with the first carrier 110. The first clearance drive 120 is used to drive the first clamping member 112 to move away from the first placement groove 1111. Figure 9 As shown, the first clearance drive 120 is used to drive the first clamping member 112 to move to the right. In this embodiment, the first clearance drive 120 drives the first clamping member 112 to make way for the first placement groove 1111, so that the terminal block 11 is suitable for being placed in or removed from the first placement groove 1111, which is stable and reliable and effectively improves the operating efficiency of the welding equipment. It can be understood that when the first clearance drive 120 is reset, the first clamping member 112 moves toward the first placement groove 1111 under the action of the first clamping elastic member 113 and can press the terminal block 11 into the first placement groove 1111.

[0131] For example, the first clearance drive 120 is disposed on the worktable 1000, that is, the first clearance drive 120 does not move with the first conveying device 100.

[0132] For example, a first clearance drive 120 is provided at the workstation where the transfer device 400 is located. When the first conveying device 100 conveys the first carrier 110 to the transfer device 400, the first clearance drive 120 at the workstation drives the first clamping member 112 to make way for the first placement slot 1111, that is, to loosen the wiring plate 11, so as to make it suitable for the first transfer mechanism 410 to grab and transfer the semi-finished product 10.

[0133] For example, the first yielding drive 120 may be configured as a telescopic drive, such as a linear cylinder.

[0134] Exemplarily, the first clearance drive member 120 is provided with a first push block 121, and the first pressing member 112 is provided with a first roller 1121. The first clearance drive member 120 drives the first push block 121 to press the first roller 1121, thereby enabling the first pressing member 112 to move away from the first placement groove 1111. Exemplarily, the first push block 121 is provided with a first inclined surface, and the first push block 121 presses the first roller 1121 through the first inclined surface. It is understood that the first push block 121 and the first roller 1121 are separable to prevent the first push block 121 from interfering with the transfer of the first carrier 110.

[0135] In one feasible embodiment, the welding equipment further includes a second clearance drive 130, with the first clearance drive 120 correspondingly disposed to the first carrier 110, and the second clearance drive 130 used to drive the second clamping member 114 to move away from the second placement groove 1112, such as... Figure 9As shown, the second clearance drive 130 is used to drive the second clamping member 114 to move to the left. In this embodiment, the second clearance drive 130 drives the second clamping member 114 to make way for the second placement groove 1112, so that the bimetallic part 12 is suitable for placement in or removal from the second placement groove 1112, which is stable and reliable and effectively improves the operating efficiency of the welding equipment. It can be understood that when the second clearance drive 130 is reset, the second clamping member 114 moves towards the second placement groove 1112 under the action of the second clamping elastic member 115 and can press the bimetallic part 12 into the second placement groove 1112.

[0136] For example, the second clearance drive 130 is disposed on the first fixed plate, that is, the second clearance drive 130 does not move with the first conveying device 100.

[0137] For example, a second clearance drive 130 is provided at the workstation where the transfer device 400 is located. When the first conveying device 100 conveys the first carrier 110 to the transfer device 400, the second clearance drive 130 at the workstation drives the second clamping member 114 to make way for the second placement slot 1112, that is, to release the bimetallic part 12, so as to make it suitable for the first transfer mechanism 410 to grab and transfer the semi-finished product 10.

[0138] For example, the second yielding drive 130 may be configured as a telescopic drive, such as a linear cylinder.

[0139] Exemplarily, the second clearance drive member 130 is provided with a second push block 131, and the second pressing member 114 is provided with a second roller 1141. The second clearance drive member 130 drives the second push block 131 to press the second roller 1141, thereby enabling the second pressing member 114 to move away from the second placement groove 1112. The second push block 131 has the same shape as the first push block 121, which will not be described in detail in this embodiment. It is understood that the second push block 131 and the second roller 1141 are separable to prevent the second push block 131 from interfering with the transfer of the first carrier 110.

[0140] For example, the end of the second clamping member 114 has a groove on the side facing the bottom surface of the second placement groove 1112. The groove has a first limiting surface 1142 and a second limiting surface 1143 that are perpendicular to each other. The bimetallic member 12 is sandwiched between the first limiting surface 1142 and the bottom surface of the second placement groove 1112, with the first limiting surface 1142 and the bottom surface of the second placement groove 1112 forming a limiting effect on the bimetallic member 12 along its thickness direction. The bimetallic member 12 is also sandwiched between the second limiting surface 1143 and the side surface of the second placement groove 1112, with the second limiting surface 1143 and the side surface of the second placement groove 1112 forming a limiting effect on the bimetallic member 12 along its width direction. For example, the end of the second clamping member 114 has a rounded corner or chamfer between it and the first limiting surface 1142, so that the bimetallic member 12 can smoothly slide into the groove under the guidance of the rounded corner or chamfer.

[0141] In this embodiment, reference is made to Figure 1 , Figure 5 , Figures 11 to 13 As shown, the second carrier 310 includes a second platform 311 and a third clamping assembly. The second platform 311 is disposed on the second conveying device 300 and has a third placement groove 3111 for placing the conductive rod 20. The third clamping assembly includes a third clamping member 312 connected to the second platform 311 and a third clamping elastic member (not shown) connected to the third clamping member 312. The third clamping member 312 is rotatable relative to the second platform 311 and can also slide relative to the second platform 311 along the rotation axis of the third clamping member 312. When the third clamping member 312 rotates to a first angle, it can avoid the bimetallic part 12 of the semi-finished product 10 along its rotation axis, so that the second transfer mechanism 420 is suitable for placing the semi-finished product 10 on the second carrier 310 or transferring the heat element assembly away from the second carrier 310. When the third clamping member 312 rotates to a second angle, it can press the bimetallic part 12 of the semi-finished product 10 onto the conductive rod 20 under the action of the third clamping elastic member, so as to achieve positioning between the semi-finished product 10 and the conductive rod 20, making the second welding device 500 suitable for welding the bimetallic part 12 and the conductive rod 20 together. It can be understood that the third clamping elastic member causes the third clamping member 312 to have a tendency to move towards the second platform 311 along its own rotation axis.

[0142] For example, the third clamping elastic element can be a spring.

[0143] In one feasible embodiment, the welding equipment further includes a clearance drive assembly, which is correspondingly disposed with the second carrier 310. The clearance drive assembly includes a docking member 320, a third clearance drive member 330, and a fourth clearance drive member 340 connected in sequence. The third clearance drive member 330 is used to drive the docking member 320 to dock with the third clamping member 312 and to drive the third clamping member 312 to slide along the rotation axis of the third clamping member 312. The fourth clearance drive member 340 is used to drive the third clamping member 312 to rotate. It is understood that the docking member 320 and the third clamping member 312 are separable to prevent the docking member 320 from interfering with the transfer of the second carrier 310. In this embodiment, after the third clearance drive 330 drives the third clamping member 312 away from the second platform 311, the fourth clearance drive 340 drives the third clamping member 312 to rotate from the second angle to the first angle. At this time, it is suitable to place the semi-finished product 10 on the second carrier 310 or to transfer the heat element assembly away from the second carrier 310. The fourth clearance drive 340 and the third clearance drive 330 are controlled to reset in sequence, and the third clamping member 312 presses the bimetallic part 12 of the semi-finished product 10 onto the conductive rod 20 under the action of the third clamping elastic member.

[0144] For example, the third clearance drive 330 is disposed on the worktable 1000, that is, the third clearance drive 330 does not move with the second conveying device 300.

[0145] For example, a clearance drive assembly is provided at the workstation where the transfer device 400 is located. When the second conveying device 300 conveys the second carrier 310 to the transfer device 400, the third clearance drive 330 and the fourth clearance drive 340 at the workstation operate in sequence to facilitate the first transfer mechanism 410 to place the semi-finished product 10 on the second carrier 310.

[0146] For example, the third yielding drive 330 can be configured as a telescopic drive, such as a linear cylinder.

[0147] For example, the fourth yielding drive 340 can be configured as a rotary cylinder or a motor reducer module.

[0148] For example, one of the mating member 320 and the third clamping member 312 is provided with a mating groove (not shown), and the other is provided with a mating protrusion (not shown). The mating protrusion is inserted into the mating groove to realize the connection between the mating member 320 and the third clamping member 312, so that the mating member 320 can drive the third clamping member 312 to move. The shape of the mating protrusion and the mating groove includes, but is not limited to, a straight line shape or a cross shape.

[0149] In one feasible embodiment, the second platform 311 is provided with a placement hole 3112, and the second carrier 310 further includes a fourth clamping member 313 slidably connected to the second platform 311 and a fourth clamping elastic member 314 connected to the fourth clamping member 313. The fourth clamping member 313 is provided with a fourth placement groove 3131 for placing the semi-finished product 10. The fourth clamping elastic member 314 enables the fourth clamping member 313 to press the semi-finished product 10 against the wall of the placement hole 3112 near the third placement groove 3111, thereby achieving the positioning of the semi-finished product 10 and ensuring that the bimetallic part 12 and the conductive rod 20 have high overlap accuracy, making the second welding device 500 suitable for positioning and welding the bimetallic part 12 and the conductive rod 20 together. It is understood that the fourth clamping member 313 is moved away from the third placement groove 3111 to facilitate the placement of the semi-finished product 10 into the fourth placement groove 3131. Understandably, the placement hole 3112 allows the semi-finished product 10 to be positioned so that the bimetallic part 12 of the semi-finished product 10 placed on the second carrier 310 is suitable for overlapping with the conductive rod 20.

[0150] Specifically, the fourth placement hole 3112 is used to accommodate the limiting wiring plate 11 to achieve the positioning of the semi-finished product 10.

[0151] Specifically, the fourth clamping elastic member 314 enables the fourth clamping member 313 to press the bimetallic member 12 against the wall of the placement hole 3112 near the third placement groove 3111. It can be understood that the fourth clamping member 313 presses the terminal block 11 against the wall of the fourth placement groove 3131, causing the terminal block 11 to press the bimetallic member 12 against the wall of the placement hole 3112 near the third placement groove 3111, thereby pressing the bimetallic member 12 against the wall of the placement hole 3112 near the third placement groove 3111.

[0152] For example, the fourth clamping elastic element 314 can be a spring.

[0153] In one feasible embodiment, the welding equipment further includes a fifth clearance drive 350, which is correspondingly disposed with the second carrier 310. The fifth clearance drive 350 is used to drive the fourth clamping member 313 to move away from the third placement groove 3111. In this embodiment, the fifth clearance drive 350 is controlled to drive the fourth clamping member 313 to move away from the third placement groove 3111, so as to facilitate the placement of the semi-finished product 10 into the fourth placement groove 3131. It can be understood that when the fifth clearance drive 350 is reset, the third clamping member 312, under the action of the third clamping elastic member, presses the bimetallic part 12 against the hole wall of the placement hole 3112 near the third placement groove 3111.

[0154] For example, the fifth clearance drive 350 is disposed on the second fixed plate, that is, the fifth clearance drive 350 does not move with the second conveying device 300.

[0155] For example, a fifth clearance drive 350 is provided at the workstation where the transfer device 400 is located. When the second conveying device 300 conveys the second carrier 310 to the transfer device 400, the fifth clearance drive 350 at the workstation is activated, and the first transfer mechanism 410 places the semi-finished product 10 on the second carrier 310 in a stable and reliable manner.

[0156] For example, the fifth yielding drive 350 can be configured as a telescopic drive, such as a linear cylinder.

[0157] Exemplarily, the fifth clearance drive member 350 is provided with a third push block 360, and the fourth clamping member 313 is provided with a third roller 3132. The fifth clearance drive member 350 drives the third push block 360 to press the third roller 3132, thereby enabling the fourth clamping member 313 to move away from the third placement groove 3111. The third push block 360 has the same shape as the first push block 121, which will not be described in detail in this embodiment. It is understood that the third push block 360 and the third roller 3132 are separable to prevent the third push block 360 from interfering with the transfer of the third carrier.

[0158] For example, to prevent the third push block 360 from interfering with the movement of the second carrier 310, the welding equipment further includes a sixth clearance drive 370 (not shown), which is disposed between the second fixed plate and the fifth clearance drive 350. The sixth clearance drive 370 is used to drive the third push block 360 to move vertically. Specifically, the sixth clearance drive 370 drives the third push block 360 to move upward, thereby clearing the second carrier 310; the sixth clearance drive 370 also drives the third push block 360 to move downward, enabling the third push block 360 to press against the third roller 3132.

[0159] In this embodiment, reference is made to Figure 1 , Figure 14 and Figure 16As shown, the welding equipment also includes a first feeding device 600, a second feeding device 700, and a first detection device 810. Along the conveying direction of the first conveying device 100, the first feeding device 600, the second feeding device 700, the first welding device 200, the first detection device 810, and the transfer device 400 are arranged in sequence. The first feeding device 600 is used to place the terminal block 11 on the first carrier 110, the second feeding device 700 is used to place the bimetallic part 12 on the first carrier 110, and the first detection device 810 is used to detect the welding quality of the terminal block 11 and the bimetallic part 12. In this embodiment, the automatic feeding of the terminal block 11 and the bimetallic component 12 can be achieved by setting the first feeding device 600 and the second feeding device 700, which effectively improves the welding efficiency of the welding equipment. The welding quality of the terminal block 11 and the bimetallic component 12 is detected by the first detection device 810. If the welding quality of the terminal block 11 and the bimetallic component 12 meets the requirements, the semi-finished product 10 is transferred to the second carrier 310 by the transfer device 400 to complete the subsequent welding operation.

[0160] In some embodiments, if the welding quality of the terminal block 11 and the bimetallic component 12 does not meet the requirements, the semi-finished product 10 can be transferred to the second carrier 310 by the transfer device 400 without further welding operations, and the semi-finished product 10 can be transferred away from the unloading station of the second conveying device 300. In other embodiments, if the welding quality of the terminal block 11 and the bimetallic component 12 does not meet the requirements, the semi-finished product 10 can be directly transferred away from the first conveying device 100.

[0161] For example, the first detection device 810 may be configured as a charge coupled device (CCD) detection module.

[0162] For example, the first detection device 810 may be disposed on the workbench 1000.

[0163] For example, a first clearance drive 120 is provided at the station where the first feeding device 600 is located. The first clearance drive 120 at the station is controlled to drive the first clamping member 112 to clearance the first placement groove 1111, so that the first feeding device 600 can place the terminal block 11 in the first placement groove 1111.

[0164] For example, a second clearance drive 130 is provided at the station where the second feeding device 700 is located. The second clearance drive 130 at the station is controlled to drive the second clamping member 114 to clearance the second placement groove 1112, so that the second feeding device 700 can place the bimetallic part 12 into the second placement groove 1112.

[0165] In this embodiment, reference is made to Figure 14 and Figure 15As shown, the first feeding device 600 includes a first vibratory feeder 610, a first vertical vibrator 620, a first material transfer mechanism 630, and a first transfer mechanism 640. The terminal block 11 within the first vibratory feeder 610 can be transferred to the first material transfer mechanism 630 via the first vertical vibrator 620. The first material transfer mechanism 630 can transfer and rotate the terminal block 11 to make it suitable for being grasped and transferred to the first carrier 110 by the first transfer mechanism 640, and can change the placement position of the terminal block 11 on the first carrier 110, ensuring stable and reliable feeding of the terminal block 11.

[0166] For example, the first transfer mechanism 630 can rotate the terminal block 11 90° around the horizontal direction.

[0167] For example, the first vibratory plate 610, the first direct vibrator 620 and the first material transfer mechanism 630 can all be mounted on the worktable 1000.

[0168] For example, the first transfer mechanism 640 may be disposed on the first fixed plate.

[0169] Specifically, the first material transfer mechanism 630 includes a first material transfer seat 631, a first material transfer slider 632, a first material transfer drive 633, a material transfer push block 634, a second material transfer drive 635, a material transfer rotating block 636, and a third material transfer drive 637. The first transfer seat 631 is provided with a first feeding channel (not shown), and the first vibrator 620 can transfer the terminal block 11 into the first feeding channel; the first transfer slider 632 is slidably disposed on the first transfer seat 631 and connected to the first transfer drive 633, the first transfer slider 632 is provided with a second feeding channel (not shown), and the first transfer drive 633 is used to drive the first transfer slider 632 to move in the vertical direction; the transfer push block 634 is slidably disposed on the first transfer seat 631 and connected to the second transfer drive 635; the transfer rotating block 636 is rotatably disposed on the first transfer seat 631 and connected to the third transfer drive 637, the transfer rotating block 636 is provided with a feeding groove (not shown), and the third transfer drive 637 is used to drive the transfer rotating block 636 to rotate. In this embodiment, the first transfer slider 632 moves down to the first feeding position, connecting the first feeding channel and the second feeding channel. Under the action of the first vibrator 620, the connector 11 in the first feeding channel can be transferred to the second feeding channel. The first transfer slider 632 moves up to the second feeding position, and the transfer rotating block 636 rotates to the first feeding angle. The second transfer driving member 635 drives the transfer pushing block 634 to push the connector 11 in the second feeding channel into the feeding trough. The transfer rotating block 636 rotates to the second feeding angle, and the first transfer mechanism 640 can grab the connector 11 in the feeding trough and transfer it to the first carrier 110. It can be understood that the rotation of the transfer rotating block 636 from the first feeding angle to the second feeding angle can complete the rotation of the connector 11. In this embodiment, the connector 11 is transferred stably and reliably within the first feeding channel, the second feeding channel, and the feeding trough.

[0170] For example, the first transfer seat 631 is disposed on the worktable 1000.

[0171] For example, the first material transfer drive 633 can be configured as a telescopic drive, such as a linear cylinder.

[0172] For example, the second material transfer drive 635 can be configured as a telescopic drive, such as a linear cylinder.

[0173] For example, the third material transfer drive 637 can be configured as a telescopic drive, such as a linear cylinder. The third material transfer drive 637 can drive the material transfer rotating block 636 to rotate via a second gear and rack structure (not shown), ensuring stability and reliability. Specifically, the second gear and rack structure includes a second gear fixed to the material transfer rotating block 636 and a second rack slidably disposed on the first material transfer seat 631. The third material transfer drive 637 is connected to the second rack. In this embodiment, the third material transfer drive 637 drives the second rack to slide, thereby driving the second gear to rotate through meshing transmission, and subsequently driving the material transfer rotating block 636 to rotate, ensuring stability and reliability.

[0174] Specifically, the first transfer mechanism 640 includes a first transfer drive 641, a second transfer drive 642, and a first transfer gripper 643 connected in sequence. The first transfer drive 641 drives the first transfer gripper 643 to move horizontally, and the second transfer drive 642 drives the first transfer gripper 643 to move vertically. For example, when the first transfer mechanism 640 operates, firstly, the first transfer drive 641 is controlled to drive the first transfer gripper 643 to move above the first material transfer mechanism 630, and the second transfer drive 642 drives the first transfer gripper 643 to move downwards, allowing the first transfer gripper 643 to grasp the rotated terminal block 11. Then, the second transfer drive 642 and the first transfer drive 641 are reset sequentially so that the first transfer gripper 643 is positioned above the first carrier 110. Next, the second transfer drive 642 is controlled to drive the first transfer gripper 643 to move downwards, allowing the first transfer gripper 643 to place the terminal block 11 on the first carrier 110 and reset the second transfer drive 642, ensuring stability and reliability.

[0175] For example, the first transfer drive 641 can be configured as a telescopic drive, such as a linear cylinder.

[0176] For example, the second transfer drive 642 can be configured as a telescopic drive, such as a linear cylinder.

[0177] For example, the first transfer gripper 643 can be configured as a gripper structure driven by a rotary finger cylinder. It is understood that when the first transfer drive member 641 drives the first transfer gripper 643 to move from above the first transfer mechanism 630 to above the first carrier 110, the first transfer gripper 643 can rotate the terminal block 11 to change the placement position of the terminal block 11 on the first carrier 110, so that the overlap between the terminal block 11 and the bimetallic member 12 is located on the edge of the first carrier 110 away from the first turntable. This allows for a more compact structure of the first welding device 200 and prevents interference between the first welding device 200 and the first carrier 110 and the first turntable during operation. The first transfer gripper 643 can rotate the terminal block 11 by 90° around the vertical direction.

[0178] In this embodiment, reference is made to Figure 16 As shown, the second feeding device 700 includes a second material transfer mechanism 710 and a second transfer mechanism 720. The second material transfer mechanism 710 is equipped with a feeding carrier (not shown), which can hold the bimetallic part 12. The second material transfer mechanism 710 can transfer the feeding carrier to the workstation where the second transfer mechanism 720 is located. The second transfer mechanism 720 is used to grab the bimetallic part 12 in the feeding carrier and transfer it to the first carrier 110. The feeding of the terminal block 11 is stable and reliable.

[0179] For example, both the second material transfer mechanism 710 and the second transfer mechanism 720 can be located on the worktable 1000.

[0180] Specifically, the second material transfer mechanism 710 includes a first conveyor line 711, a second conveyor line 712, a first pusher drive 713, and a second pusher drive 714. The first conveyor line 711 and the second conveyor line 712 are arranged side-by-side with opposite conveying directions. The first pusher pushes the loading carrier located at the unloading end of the first conveyor line 711 to the loading end of the second conveyor line 712, and the second pusher pushes the loading carrier located at the unloading end of the second conveyor line 712 to the loading end of the first conveyor line 711, thereby realizing the transfer of the loading carrier between the first conveyor line 711 and the second conveyor line 712. It is understood that the unloading end of the first conveyor line 711 is provided with a first stop (not shown) to prevent the carrier from detaching from the first conveyor line 711; the unloading ends of the second conveyor lines 712 are all provided with second stops (not shown) to prevent the carrier from detaching from the second conveyor line 712. The second transfer mechanism 720 is capable of grabbing the bimetallic part 12 in the loading carrier at the unloading end of the first conveyor line 711. For example, the unloading end of the first conveyor line 711 has two loading carriers, and along the conveying direction of the first conveyor line 711, the two loading carriers and the first stop block abut against each other in sequence. The second transfer mechanism 720 is capable of grabbing the bimetallic part 12 in the one of the two loading carriers that is far away from the first stop block, or grabbing the bimetallic part 12 in the loading carrier that abuts against the first stop block.

[0181] For example, the first pushing drive 713 can be configured as a telescopic drive, such as a linear cylinder. The first pushing drive 713 can push the loading carrier through a first abutting member (not shown).

[0182] For example, the second pushing drive 714 can be configured as a telescopic drive, such as a linear cylinder. The second pushing drive 714 can push the loading carrier through a second abutment (not shown).

[0183] Specifically, the second transfer mechanism 720 includes a third transfer drive 721, a fourth transfer drive 722, and a second transfer gripper 723 connected in sequence. The third transfer drive 721 is used to drive the second transfer gripper 723 to move horizontally, and the fourth transfer drive 722 is used to drive the second transfer gripper 723 to move vertically. For example, when the second transfer mechanism 720 is in operation, firstly, the third transfer drive 721 is sequentially controlled to drive the second transfer gripper 723 to move above the second transfer mechanism 710, and the fourth transfer drive 722 drives the second transfer gripper 723 to move downward, so that the second transfer gripper 723 grabs the bimetallic part 12 in the loading carrier; then, the fourth transfer drive 722 and the third transfer drive 721 are sequentially reset so that the second transfer gripper 723 is located above the first carrier 110, and then the fourth transfer drive 722 is controlled to drive the second transfer gripper 723 to move downward, so that the second transfer gripper 723 places the bimetallic part 12 on the first carrier 110 and resets the fourth transfer drive 722, which is stable and reliable.

[0184] For example, the third transfer drive 721 includes, but is not limited to, a linear motor or a motor-driven lead screw slide module.

[0185] For example, the fourth transfer drive 722 can be configured as a telescopic drive, such as a linear cylinder.

[0186] For example, the second transfer gripper 723 may be configured as a gripper structure driven by a finger cylinder.

[0187] In this embodiment, reference is made to Figure 1 and Figure 17 As shown, the welding equipment also includes a third feeding device 900 and a second detection device 820. Along the conveying direction of the second conveying device 300, the third feeding device 900, the transfer device 400, the second welding device 500, and the second detection device 820 are sequentially arranged. The third feeding device 900 is used to place the conductive rod 20 onto the second carrier 310, and the second detection device 820 is used to detect the welding quality of the bimetallic part 12 and the conductive rod 20. In this embodiment, the third feeding device 900 enables automatic feeding of the conductive rod 20, effectively improving the welding efficiency of the welding equipment; and the second detection device 820 detects the welding quality of the bimetallic part 12 and the conductive rod 20 to classify and transfer qualified and unqualified heat-generating components.

[0188] For example, the second detection device 820 can be configured as a CCD detection module.

[0189] For example, the second detection device 820 may be disposed on the workbench 1000.

[0190] In this embodiment, reference is made to Figure 17As shown, the third feeding device 900 includes a second vibratory feeder 910, a second vertical vibrator 920, a third material transfer mechanism 930, a third transfer mechanism 940, and a fourth transfer mechanism 950. The conductive rod 20 within the second vibratory feeder 910 can be transferred to the third material transfer mechanism 930 via the second vertical vibrator 920. The third material transfer mechanism 930 is used to lift the conductive rod 20. The third transfer mechanism 940 is used to grasp and rotate the lifted conductive rod 20. The fourth transfer mechanism 950 is used to grasp the rotated conductive rod 20 and transfer it to the second carrier 310. The feeding of the conductive rod 20 is stable and reliable. It is understood that the bimetallic component 12 is more convenient to connect with the rotated conductive rod 20.

[0191] For example, the third transfer mechanism 940 can rotate the conductive rod 20 180° around the horizontal direction.

[0192] For example, the second vibratory plate 910, the second linear vibrator 920, the third material transfer mechanism 930 and the third transfer mechanism 940 are all located on the worktable 1000.

[0193] For example, the fourth transfer mechanism 950 is disposed on the second fixed plate.

[0194] Specifically, the third material transfer mechanism 930 includes a second material transfer seat 931, a second material transfer slider 932, and a fourth material transfer drive 933. The second material transfer seat 931 has a third feeding channel, and the second vertical vibrator 920 can transfer the conductive rod 20 into the first feeding channel. The second material transfer slider 932 is slidably mounted on the second material transfer seat 931 and connected to the fourth material transfer drive 933. The second material transfer slider 932 has a fourth feeding channel, and the fourth material transfer drive 933 drives the second material transfer slider 932 to move vertically. When the second material transfer slider 932 moves down to the third feeding position, the third feeding channel connects with the fourth feeding channel. Under the action of the second vertical vibrator 920, the conductive rod 20 in the third feeding channel can be transferred into the fourth feeding channel. When the second material transfer slider 932 moves up to the fourth feeding position, the third transfer mechanism 940 can grasp the conductive rod 20 in the fourth feeding channel, ensuring stability and reliability.

[0195] For example, the second transfer seat 931 is provided on the worktable 1000.

[0196] For example, the fourth material transfer drive 933 can be configured as a telescopic drive, such as a linear cylinder.

[0197] Specifically, the third transfer mechanism 940 includes a fifth transfer drive member 941 and a third transfer gripper 942 disposed on the fifth transfer drive member 941. The fifth transfer drive member 941 drives the third transfer gripper 942 to move horizontally, and the gripper portion of the third transfer gripper 942 is capable of rotation and gripping the conductive rod 20. In this embodiment, when the third transfer gripper 942 moves to the fifth loading position, it can grip the conductive rod 20 on the third transfer mechanism 930; when the third transfer gripper 942 moves to the sixth loading position, the gripper portion of the third transfer gripper 942 rotates and rotates the conductive rod 20, and the fourth transfer mechanism 950 can grip the rotated conductive rod 20 stably and reliably.

[0198] For example, the fifth transfer drive 941 can be configured as a telescopic drive, such as a linear cylinder.

[0199] For example, the third transfer gripper 942 may be configured as a gripper structure driven by a rotating finger cylinder.

[0200] Specifically, the fourth transfer mechanism 950 includes a sixth transfer drive 951, a seventh transfer drive 952, and a fourth transfer gripper 953 connected in sequence. The sixth transfer drive 951 drives the fourth transfer gripper 953 to move horizontally, and the seventh transfer drive 952 drives the fourth transfer gripper 953 to move horizontally. For example, when the fourth transfer mechanism 950 operates, firstly, the sixth transfer drive 951 is sequentially controlled to drive the fourth transfer gripper 953 to move above the third transfer mechanism 940, and the seventh transfer drive 952 drives the fourth transfer gripper 953 to move downwards, whereby the fourth transfer gripper 953 grasps the rotated conductive rod 20. Then, the seventh transfer drive 952 and the sixth transfer drive 951 are sequentially reset so that the fourth transfer gripper 953 is positioned above the second carrier 310. Next, the seventh transfer drive 952 is controlled to drive the fourth transfer gripper 953 to move downwards, whereby the fourth transfer gripper 953 places the conductive rod 20 onto the second carrier 310 and resets the seventh transfer drive 952, ensuring stability and reliability.

[0201] For example, the sixth transfer drive 951 can be configured as a telescopic drive, such as a linear cylinder.

[0202] For example, the seventh transfer drive 952 can be configured as a telescopic drive, such as a linear cylinder.

[0203] For example, the fourth transfer gripper 953 may be configured as a gripper structure driven by a finger cylinder.

[0204] For example, the seventh transfer drive 952 may be connected to two fourth transfer grippers 953 to ensure stable and reliable transfer of the conductive rod 20.

[0205] In this embodiment, reference is made to Figure 1 and Figure 18 As shown, the welding equipment also includes a feeding device 1100 and a feeding conveyor line 1200. Along the conveying direction of the second conveyor line 712, the feeding device 1100 is located between the third loading device 900 and the second inspection device 820. The feeding device 1100 can transfer the heat element components with qualified welding quality from the second carrier 310 to the feeding conveyor line 1200, which is used to transfer the heat element components to the next station. The semi-finished product 10 and the heat element components with unqualified welding quality can also be transferred through the feeding device 1100.

[0206] For example, both the unloading device 1100 and the unloading conveyor line 1200 can be mounted on the workbench 1000.

[0207] For example, a clearance drive assembly is provided at the station where the unloading device 1100 is located. The clearance drive assembly at the station is controlled to drive the third clamping member 312 to rotate to a first angle so that the unloading device 1100 can transfer the heat element assembly away from the second carrier 310.

[0208] Specifically, the unloading device 1100 includes a first unloading drive 1110, a second unloading drive 1120 and an unloading gripper 1130 connected in sequence. The first unloading drive 1110 is used to drive the unloading gripper 1130 to move horizontally, and the second unloading drive 1120 is used to drive the unloading gripper 1130 to move vertically. For example, when the unloading device 1100 is operating, firstly, the first unloading drive 1110 is sequentially controlled to drive the unloading gripper 1130 to move above the second carrier 310, and the second unloading drive 1120 drives the unloading gripper 1130 to move downward, so that the unloading gripper 1130 can grab the heat element component; then, the second unloading drive 1120 and the first unloading drive 1110 are sequentially reset, and the second unloading drive 1120 is controlled to drive the unloading gripper 1130 to move downward, so that the unloading gripper 1130 can place the heat element component on the unloading conveyor line 1200 and reset the second unloading drive 1120, which is stable and reliable.

[0209] For example, the first feeding drive unit 1110 includes, but is not limited to, a motor-driven lead screw slide module or a cylinder-driven slide module.

[0210] For example, the second feeding drive 1120 can be configured as a telescopic drive, such as a linear cylinder.

[0211] For example, the unloading gripper 1130 can be configured as a gripper structure driven by a finger cylinder.

[0212] For example, the second unloading drive 1120 is connected to two unloading claws 1130. One of the two unloading claws 1130 is used to grip the wiring board 11 of the heat element assembly, and the other is used to grip the conductive rod 20 of the heat element assembly, so as to ensure that the transfer of the heat element assembly is stable and reliable.

[0213] In this embodiment, the welding equipment further includes a third detection device 830, located between the transfer device 400 and the second welding device 500 along the conveying direction of the second conveyor line 712. The third detection device 830 is used to detect the positions of the semi-finished product 10 and the conductive rod 20 on the second carrier 310. When the positions of the semi-finished product 10 and the conductive rod 20 on the second carrier 310 meet the requirements, the second welding device 500 welds the bimetallic part 12 and the conductive rod 20 together; and semi-finished products 10 and the conductive rod 20 whose positions do not meet the requirements can be transferred by the unloading device 1100.

[0214] For example, the third detection device 830 can be configured as a CCD detection module.

[0215] For example, the third detection device 830 may be disposed on the workbench 1000.

[0216] For example, the specific operating steps of the welding equipment are as follows:
