[0003] The device for actually welding the thermoelectric cooler wiring and the thermoelectric cooler mainly uses an electric clamping device to clamp a single thermoelectric cooler wiring, and uses a welding device that moves synchronously with the electric clamping device to weld the front end of the thermoelectric cooler wiring combined with the thermoelectric cooler. The subsequent welding of the thermoelectric cooler wiring is achieved by gradually moving the electric clamping device and the welding device as a whole and repeating the above steps.

[0004] Although the above technical solution can weld and connect each thermoelectric cooler wiring, due to the large number of thermoelectric cooler wirings during the welding process, and the welding position between the thermoelectric cooler wiring and the top of the thermoelectric cooler needs to be accurately positioned, the method of clamping the thermoelectric cooler wiring in sequence and welding is time-consuming and laborious, and it is difficult to ensure the positioning accuracy between the thermoelectric cooler wiring and the top of the thermoelectric cooler; in addition, since the thermoelectric cooler wiring is in a randomly bent state before welding, the front end of the thermoelectric cooler wiring may not be straight, resulting in the thermoelectric cooler wiring not being able to fit tightly with the welding position on the top of the thermoelectric cooler during the welding process, and then resulting in the occurrence of false soldering, affecting the welding quality and the use of the thermoelectric cooler after welding.

[0015] The beneficial effects of the present invention are as follows: First, the present invention drives the track sleeve through the power element and enables the sliding sleeve and the arc-shaped clamping plate to straighten the rear end of the refrigeration chip wiring backward. On the one hand, it can prevent the rear end of the refrigeration chip wiring from staying above the welding position on the top of the refrigeration chip and affecting the welding of the front end of the refrigeration chip wiring. On the other hand, by straightening the rear end of the refrigeration chip wiring backward, it can also prevent the front end of the refrigeration chip wiring from warping, so as to ensure that the refrigeration chip wiring can closely fit the welding position on the top of the refrigeration chip and facilitate the welding gun to weld the refrigeration chip wiring and the refrigeration chip, ensuring the welding accuracy.

[0016] Second, the present invention uses the blocking element to limit the distance that the electric slider drives the assembly block, the connecting element and the welding gun to move synchronously to the right, so that the welding gun can accurately align with the refrigeration chip wiring for welding, ensuring the welding accuracy. At the same time, with the lifting plate cooperating with the elastically telescopic inner embedded rod and the outer sleeve frame and the blocking plate, the position of the blocking plate is accurately corresponding to the position of the refrigeration chip wiring, further improving the welding accuracy of the welding gun for the refrigeration chip wiring.

[0017] Third, the present invention uses the pressing element to cooperate with the connecting element to straighten the front end of the refrigeration chip wiring forward and press it downward before welding, so as to ensure that the front end of the refrigeration chip wiring abuts against the welding position of the refrigeration chip and facilitate the welding gun to weld the refrigeration chip wiring and the refrigeration chip. At the same time, by pressing the front end of the refrigeration chip wiring downward with the pressing rod, it can ensure that the welding gun accurately aligns with the front end of the refrigeration chip wiring after the downward pressing for welding, ensuring the welding accuracy. And through the way that the front end of the refrigeration chip wiring closely fits the refrigeration chip, the situation of false welding can be avoided.

[0018] IV. The present invention adopts a method in which the clamping unit cooperates with the adjusting stud in a scissor structure to equally adjust the position of the limit slider, so as to equally adjust the position of the clamped cold plate wiring. At the same time, the method of clamping and positioning multiple cold plate wirings synchronously can also improve the positioning accuracy. Moreover, the cooperation of the outer sleeve block and the inner embedded block with the left pressing block and the right pressing block ensures that the positions of all the clamped cold plate wirings are consistent. At the same time, the method of positioning the cold plate wiring by the mutually staggered left pressing block and right pressing block can not only adapt to cold plate wirings of different sizes, but also make the clamping of the cold plate wiring more stable.

Specific embodiments

[0033] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0034] Refer to Figures 1-2 , an electronic component high-temperature welding connection device, including a positioning frame 1, a positioning groove 11 is arranged in the positioning frame 1, a first cylinder 2 is fixed at the top fixed end, a positioning unit 3 for positioning electronic components is arranged in the positioning groove 11, a pushing end of the first cylinder 2 is fixed with an assembly plate 21, a clamping unit 4 for clamping the wiring of electronic components is arranged on the assembly plate 21, and a welding unit 5 is arranged on the front side of the assembly plate 21.

[0035] In the present invention, the positioning unit 3 positions the thermoelectric cooler, and at the same time, the clamping unit 4 positions the wiring of multiple thermoelectric coolers at equal intervals synchronously, so that the wiring of the thermoelectric cooler can adapt to different sizes of thermoelectric coolers, and then cooperates with the welding unit 5 to weld the wiring of each positioned thermoelectric cooler in sequence. Specifically, first, the positioning unit 3 positions the thermoelectric cooler, and makes the position for welding the wiring of the thermoelectric cooler align with the clamping unit 4. Subsequently, the clamping unit 4 positions and clamps the wiring of multiple thermoelectric coolers. After the wiring of the thermoelectric cooler is positioned and clamped, control the first cylinder 2 to push down the assembly plate 21 and the clamping unit 4 until the wiring of the thermoelectric cooler moves to the welding position. Then, control the welding unit 5 to weld the wiring of the thermoelectric cooler and the thermoelectric cooler from left to right in sequence.

[0036] Refer to Figure 1 , Figure 3 and Figure 11 , the positioning unit 3 includes a threaded rod 31 threadedly connected to the front side wall of the positioning frame 1. A pushing disk 311 is fixed to the rear end of the threaded rod 31, and a crank is fixed to the front end of the threaded rod 31. The left and right sides of the positioning groove 11 are symmetrically connected by elastic telescopic rods to bending positioning plates 312 for positioning the left and right positions of electronic components.

[0037] The positioning unit 3 is used to adjust the position of the thermoelectric cooler, so that the position of the thermoelectric cooler is adjusted, and it is ensured that the welding position at the top of the thermoelectric cooler is located below the clamping unit 4. Specifically, first, place the thermoelectric cooler to be welded into the positioning groove 11 from top to bottom. At this time, the bending positioning plates 312 on both sides will be pressed outward by the upper part of the thermoelectric cooler, so that the thermoelectric cooler is centered under the elastic force of the elastic telescopic rods. Subsequently, the operator turns the crank to make the threaded rod 31 rotate, and drives the pushing disk 311 to push the thermoelectric cooler backward, so that the welding position at the top of the thermoelectric cooler moves below the clamping unit 4 and the positioning of the thermoelectric cooler is completed.

[0038] Refer to Figure 2 , Figure 4 and Figure 5 , the clamping unit 4 includes horizontal sliding grooves opened on the left and right sides of the assembly plate 21. A plurality of limit sliders 41 are slidably connected in each horizontal sliding groove. A moving column 411 is fixed to the bottom of the limit slider 41. A fixed column 412 is installed at the center position of the bottom of the assembly plate 21 and between the two horizontal sliding grooves. Two rotating rods 413 are rotatably installed on both the fixed column 412 and the moving column 411. All the rotating rods 413 together form a scissor structure. Clamping elements 42 are provided at the bottom of both the fixed column 412 and the moving column 411. A power element 43 for stably clamping in cooperation with the clamping element 42 is provided on the rear side surface of the assembly plate 21; an adjusting screw for adjusting the position of the clamping element 42 is threadedly connected to the assembly plate 21, and the left end of the adjusting screw is connected to the limit slider 41 on the right side.

[0039] The clamping unit 4 is used to synchronously clamp the wiring of the refrigeration chip. At the same time, with the scissor structure cooperating with the adjusting stud, it can synchronously adjust the positions of the limit sliders 41 at equal intervals, thereby adjusting the positions of the clamping elements 42 at equal intervals. Furthermore, the wiring of the refrigeration chip after clamping can correspond one by one to the welding positions on the top of the positioned refrigeration chip. At the same time, the method of synchronously clamping and positioning the wiring of the refrigeration chip can also improve the positioning accuracy.

[0040] Refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 10 , the clamping element 42 includes a U-shaped frame 421 fixed to the bottom of the fixed column 412 or the moving column 411. A horizontal rod 422 is connected between the two vertical sections of the U-shaped frame 421. Claw jaws 423 are symmetrically and slidably connected to the left and right on the horizontal rod 422. A horizontal spring is connected between the two claw jaws 423. A limiting structure is commonly connected to the opposite sides of the two claw jaws 423; the limiting structure includes an outer sleeve block 424 and an inner embedded block 425 respectively fixed to the opposite sides of the left and right claw jaws 423. Left pressing blocks 426 and right pressing blocks 427 are respectively fixed to the opposite sides of the two claw jaws 423 and above the outer sleeve block 424. The bottoms of the left pressing block 426 and the right pressing block 427 are provided with symmetric slopes on the left and right, and the positions of the left pressing block 426 and the right pressing block 427 are staggered from each other.

[0041] The clamping element 42 can be pushed by the power element 43 to position and clamp the wiring of the refrigeration chip. At the same time, through the cooperation of the outer sleeve block 424 and the inner embedded block 425 with the left pressing block 426 and the right pressing block 427, it ensures that the positions of all the clamped wiring of the refrigeration chips are the same. At the same time, the method of positioning the wiring of the refrigeration chip by the staggered left pressing block 426 and right pressing block 427 can not only adapt to the wiring of refrigeration chips of different sizes, but also make the clamping of the wiring of the refrigeration chip more stable.

[0042] Specifically, when the refrigeration plate is positioned, the rotation of the adjustment stud is controlled according to the size of the refrigeration plate and the welding position of the refrigeration plate to adjust the position of the limit slider 41 on the right side. After the adjustment is completed, all the limit sliders 41 will adjust the position synchronously due to the scissor-type structure composed of all the rotating rods 413. Then the operator places all the refrigeration plate wiring on the top of the outer sleeve block 424 and the inner sleeve block 425 in turn, and then pushes the two clamps 423 by controlling the power element 43, so that the clamps 423 move toward each other. At this time, the outer sleeve block 424 will be sleeved on the inner sleeve block 425 and against the bottom of the refrigeration plate wiring. At the same time, the left pressure block 426 and the right pressure block 427 will move toward each other and staggered, and the left pressure block 426 and the right pressure block 427 will press the refrigeration plate wiring with the bottom, thereby completing the clamping and positioning of the refrigeration plate wiring, so that all the positioned refrigeration plate wiring is stable and at the same height.

[0043] See also Figures 5-9 The power element 43 includes an L-shaped lower extension plate 431 fixed to the rear side of the collecting plate 21, a No. 2 cylinder 432 is installed on the front side of the vertical section of the L-shaped lower extension plate 431, and a matching plate 433 is fixed to the pushing end of the No. 2 cylinder 432. The matching plate 433 is symmetrically provided with matching slide grooves, each of which is slidably connected with a matching slider 41 in the corresponding horizontal slide groove, and a moving plate 434 is fixed to the front end of each matching slider and the center position of the front side of the matching plate 433. A positioning seat 435 is fixed to the top of the moving plate 434 on the matching slider, and a positioning rod 436 is fixed to the rear side of each U-shaped frame 421 and the position corresponding to the positioning seat 435. The positioning rod 436 slides through the positioning seat 435, and a pushing rod 437 for pushing each clamp 423 inward is symmetrically fixed to the front side of the moving plate 434, and a pushing slope for pushing the clamp 423 is provided on the side of the pushing rod 437.

[0044] The power element 43 also includes a rear-pushing structure connected between each clamping jaw 423 and the corresponding pushing rod 437, and the rear-pushing structure includes a rear extension rod 438 fixed on the rear side of each clamping jaw 423, a sliding sleeve 439 is sleeved on the rear extension rod 438, and arc-shaped clamping plates 440 are symmetrically fixed to the opposite sides of the two sliding sleeves 439, a circular plate 441 is fixed to the rear end of the rear extension rod 438, and a compression spring is connected to the circular plate 441 and the sliding sleeve 439, and an extension plate 442 is fixed to the rear side of the clamping jaw 423 and above the sliding sleeve 439, and track sleeves 443 are rotatably installed on the opposite sides of the two extension plates 442, and the track sleeves 443 are symmetrically provided with track grooves from top to bottom, a lower slide rod 444 is fixed to the side of the sliding sleeve 439 at the position corresponding to the track groove, and an upper slide rod 446 is fixed to the side of the pushing rod 437 at the position corresponding to the track groove through a connecting block 445.

[0045] The power element 43 is used to push the jaw 423, so that the jaw 423 clamps the connection of the refrigeration sheet. Moreover, the moving plate 434 can also adaptively align with the position of the clamping element 42 through the positioning rod 436 and the positioning seat 435, so as to ensure accurate pushing of the jaw 423. At the same time, it can also use the backward-straightening structure to straighten the rear end of the refrigeration sheet connection backward during the clamping process, so as to avoid the situation that the front end of the refrigeration sheet connection fails to fit the welding position of the refrigeration sheet due to excessive bending of the rear end of the refrigeration sheet connection.

[0046] Specifically, after the operator places all the refrigeration sheet connections on the tops of the outer sleeve block 424 and the inner embedded block 425 in sequence, the second cylinder 432 is controlled to drive the coordination plate 433 to move forward. At this time, due to the combined limiting effect of the positioning seat 435 and the positioning rod 436, the moving plate 434 just aligns with the front jaw 423. When the moving plate 434 moves forward with the coordination plate 433, the two push rods 437 will push the jaw 423 respectively through the push ramps, so as to cooperate with the left pressing block 426 and the right pressing block 427 to fix the position of the refrigeration sheet connection. And during the forward movement of the push rod 437, the push rod 437 drives the upper sliding rod 446 to move forward, so that the track sleeve 443 rotates and pushes the lower sliding rod 444 and the sliding sleeve 439 backward, so that the two arc-shaped clamping plates 440 move backward while closing towards the refrigeration sheet connection as the jaws 423 move towards each other. Furthermore, the rear end of the refrigeration sheet connection is straightened by the arc-shaped clamping plates 440, so that the rear end of the refrigeration sheet connection is far away from the refrigeration sheet position.

[0047] It should be noted that since the front end of the refrigeration sheet connection is used for welding with the refrigeration sheet, the rear end of the refrigeration sheet connection does not need to be above the refrigeration sheet. And the power element 43 and the backward-straightening structure will not be at the welding position of the refrigeration sheet. Therefore, the size of the refrigeration sheet will not hinder the actions of the power element 43 and the backward-straightening structure.

[0048] Refer to Figure 4 、 Figure 5 、 Figure 8 and Figure 10 As shown in FIGS.

[0049] The welding unit 5 is used to weld the closely attached refrigeration chips and the wiring of the refrigeration chips. At the same time, through the pressing element 53 cooperating with the connecting element 52, it can ensure that the wiring of the refrigeration chip is closely attached to the welding position of the refrigeration chip, so as to facilitate the welding gun 512 to weld the wiring of the refrigeration chip and the refrigeration chip, prevent virtual welding, and at the same time, the blocking element 54 can accurately control the movement of the welding gun 512, so that the welding gun 512 aligns with each wiring of the refrigeration chip for welding, ensuring the welding accuracy, and at the same time ensuring the cooperation between the pressing element 53 and the connecting element 52.

[0050] Refer to Figure 5 、 Figure 8 and Figure 10 The pressing element 53 includes front extension rods 531 symmetrically fixed on the front side surface of the clamping element 42 from left to right. A horizontal sliding sleeve 532 is sleeved on each front extension rod 531. A round cap 533 is fixed at the front end of each front extension rod 531. A connecting spring is connected between the round cap 533 and the horizontal sliding sleeve 532. Inner grooves are symmetrically arranged on the opposite sides of the two horizontal sliding sleeves 532. A pressed block 534 is connected in each inner groove through a plurality of inner springs. A pressed inclined block 535 is fixed on the top of each horizontal sliding sleeve 532.

[0051] The connecting element 52 includes an electric push rod 521 fixed at the bottom of the assembly block 511. The pushing end of the electric push rod 521 is fixed with a horizontal plate 522. The bottom of the horizontal plate 522 is connected to the welding gun 512 through a mounting block 523. A fixed rod 524 is fixed on the rear side surface of the horizontal plate 522. Pressing inclined blocks 525 for pressing the pressed inclined blocks 535 are symmetrically fixed on the left and right sides at the rear end of the fixed rod 524. A downward pressing rod 526 is fixed at the bottom of the pressed inclined block 535.

[0052] The pressing element 53 is used to cooperate with the connecting element 52 to straighten and press down the front end of the wiring of the refrigeration chip forward before welding, so as to ensure that the front end of the wiring of the refrigeration chip abuts against the welding position of the refrigeration chip, and facilitate the welding gun 512 to weld the wiring of the refrigeration chip and the refrigeration chip. At the same time, in the way that the downward pressing rod 526 presses down the front end of the wiring of the refrigeration chip, it can ensure that the welding gun 512 accurately aligns with the front end of the wiring of the refrigeration chip after pressing down for welding, ensuring the welding accuracy.

[0053] Specifically, after the wiring of the thermoelectric cooler is positioned and the rear end is straightened backward, the electric slider is controlled to drive the assembly block 511, the connecting element 52, and the welding torch 512 to move synchronously to the right until the blocking element 54 blocks the movement of the assembly block 511, the connecting element 52, and the welding torch 512. At this time, the assembly block 511, the connecting element 52, and the welding torch 512 are just located at the wiring position of the thermoelectric cooler. Subsequently, the electric push rod 521 is controlled to push the horizontal plate 522 and the pressing inclined block 525 downward. The pressing inclined block 525 will push the pressed inclined block 535 through the inclined surface on the pressing inclined block 525 and cause the pressed inclined block 535 to move forward. Furthermore, the pressed inclined block 535 drives the horizontal sliding sleeve 532 and the pressed block 534 to move forward, so that the part of the front end of the thermoelectric cooler wiring that originally sagged due to gravity is straightened by the lifting action of the pressed block 534. Finally, the lower pressing rod 526 is used to press the front end of the thermoelectric cooler wiring downward, so that the front end of the thermoelectric cooler wiring is closely attached to the welding position of the thermoelectric cooler. Subsequently, the welding torch 512 is controlled to weld the closely attached thermoelectric cooler wiring and the thermoelectric cooler. By this way of closely attaching the front end of the thermoelectric cooler wiring to the thermoelectric cooler, the situation of false soldering can be avoided.

[0054] Refer to Figure 4 and Figure 5 and Figure 12 The blocking element 54 includes connecting columns 541 symmetrically fixed to the front end of the top of the assembly plate 21 from left to right. A front extension plate 542 is commonly fixed to the tops of the two connecting columns 541. A third cylinder 543 is fixed to the bottom of the front extension plate 542. A lifting plate 544 is fixed to the pushing end of the third cylinder 543; a telescopic blocking structure is provided on the limiting slider 41, and a blocked plate 545 blocked by the telescopic blocking structure is fixed to the top of the assembly block 511; the telescopic blocking structure includes an upper slot opened on the top of the assembly plate 21 corresponding to the position of the horizontal sliding groove. An inner embedded rod 546 is fixed to the top of the limiting slider 41 corresponding to the position of the upper slot. An outer sleeve frame 547 is sleeved on the inner embedded rod 546. A tension spring is connected between the inside of the outer sleeve frame 547 and the top of the inner embedded rod 546. A receiving lifting rod 548 is fixed to the front end of the outer sleeve frame 547. A blocking plate 549 is fixed to the front end of the receiving lifting rod 548. A blocking plate 549 is also fixed to the center position of the front end of the lifting plate 544. The heights of all the blocking plates 549 increase sequentially from left to right.

[0055] The blocking element 54 is used to limit the distance that the electric slider drives the assembly block 511, the connecting element 52, and the welding torch 512 to move synchronously to the right, so that the welding torch 512 can accurately align with the thermoelectric cooler wiring for welding, ensuring the welding accuracy. At the same time, with the cooperation of the lifting plate 544, the elastically telescopic inner embedded rod 546 and the outer sleeve frame 547, and the blocking plate 549, the position of the blocking plate 549 is accurately corresponding to the position of the thermoelectric cooler wiring, further improving the welding accuracy of the welding torch 512 for the thermoelectric cooler wiring.

[0056] Specifically, when the spacing of the limit slider 41 is adjusted by the scissor-type structure, the embedded rod 546, the outer frame 547 and the lifted rod 548 will move together and be consistent with the spacing of the limit slider 41. At this time, the blocking plate 549 will be consistent with the wiring position of the clamped refrigeration plate.

[0057] When the electric slider is controlled to drive the assembly block 511, the connecting element 52 and the welding gun 512 to move to the right synchronously, the blocked plate 545 will be blocked by the blocking plate 549. At this time, the pressing element 53 is controlled to cooperate with the connecting element 52 to enable the welding gun 512 to weld the refrigeration plate wiring. After the welding is completed, the No. 3 cylinder 543 is controlled to drive the lifting plate 544 to move upward. At this time, due to the lifting effect of the lifting plate 544 on the lifted rod 548, all the lifted rods 548 synchronously drive the blocking plate 549 to rise. At this time, the blocked plate 545 can pass under the nearest blocking plate 549. Then, when the electric slider is controlled to drive the assembly block 511, the connecting element 52 and the welding gun 512 to move to the right synchronously, the blocked plate 545 will be blocked by the second blocking plate 549 from left to right, and then the above operation is repeated until the welding gun 512 completes the welding of all the refrigeration plate wiring.

[0058] The working steps of the present invention are as follows: the first step is to place the refrigeration plate to be welded from top to bottom in the positioning groove 11. At this time, the bent positioning plates 312 on both sides will be pressed outward by the refrigeration plate due to the resistance of the upper part, so that the refrigeration plate is centered by the elastic force of the elastic telescopic rod. Then the operator shakes the handle to rotate the threaded rod 31, and drives the pushing plate 311 to push the refrigeration plate backward, thereby moving the welding position at the top of the refrigeration plate to the bottom of the clamping unit 4 and completing the positioning of the refrigeration plate.

[0059] In the second step, when the refrigeration plate is positioned, the rotation of the adjustment stud is controlled according to the size of the refrigeration plate and the welding position of the refrigeration plate to adjust the position of the limit slider 41 on the right side. After the adjustment is completed, all the limit sliders 41 will adjust their positions synchronously due to the scissor-type structure composed of all the rotating rods 413. Then the operator places all the refrigeration plate connections on the top of the outer cover block 424 and the embedded block 425 in turn.

[0060] Subsequently, the power element 43 is controlled to push the two jaws 423, so that the jaws 423 move towards each other. At this time, the outer sleeve block 424 will be sleeved on the inner sleeve block 425 and abut against the bottom of the refrigeration chip wiring. At the same time, the left pressing block 426 and the right pressing block 427 will move towards each other and stagger. The left pressing block 426 and the right pressing block 427 will press against the refrigeration chip wiring from the bottom, thus completing the clamping and positioning of the refrigeration chip wiring, making all the positioned refrigeration chip wirings stable and at the same height. Moreover, the arc-shaped clamping plate 440 in the power element 43 will also straighten the rear end of the refrigeration chip wiring, making the rear end of the refrigeration chip wiring away from the refrigeration chip position.

[0061] In the third step, when the positioning of the refrigeration chip wiring is completed and the rear end is straightened backward, control the electric slider to drive the assembly block 511, the connecting element 52 and the welding torch 512 to move synchronously to the right until the blocking element 54 blocks the movement of the assembly block 511, the connecting element 52 and the welding torch 512. At this time, the assembly block 511, the connecting element 52 and the welding torch 512 are just located at the position of the refrigeration chip wiring.

[0062] In the fourth step, when the welding torch 512 corresponds to the position of the refrigeration chip wiring, control the electric push rod 521 to push the horizontal plate 522 and the pressing inclined block 525 downward. The pressing inclined block 525 will push the pressed inclined block 535 through the inclined surface on the pressing inclined block 525 and make the pressed inclined block 535 move forward. Furthermore, the pressed inclined block 535 drives the horizontal sliding sleeve 532 and the pressed block 534 to move forward, so that the part of the front end of the refrigeration chip wiring that originally sagged due to gravity is straightened by the lifting action of the pressed block 534. Finally, press the front end of the refrigeration chip wiring downward through the downward pressing rod 526, so that the front end of the refrigeration chip wiring is closely attached to the welding position of the refrigeration chip. Subsequently, control the welding torch 512 to weld the closely attached refrigeration chip wiring and the refrigeration chip.

[0063] In the fifth step, after the welding torch 512 completes the welding of the first refrigeration chip wiring, control the blocking element 54 to adjust the height of blocking the displacement of the electric slider, and then control the electric slider to drive the assembly block 511, the connecting element 52 and the welding torch 512 to move synchronously to the right until the electric slider stops moving again due to the blocking element 54. Subsequently, repeat the operations of the connecting element 52 and the pressing element 53 above, and so on until the welding torch 512 completes the welding of all the refrigeration chip wirings.

Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, and still be covered by the protection scope of the present invention.
