[0033] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solution of the present invention and should not be regarded as the entire invention or as a limitation or restriction of the technical solution of the present invention.

[0034] Example 1:

[0035] Key References Figure 1-5 A fixed plate 12 is fixedly connected to the left side of the riser 3. Four first slides 9 are slidably connected to the fixed plate 12 in a sequentially upward and downward position-limiting manner from front to back. The four first slides 9 are equidistantly placed on the fixed plate 12. Four L-shaped plates 6 are fixedly connected to the riser 3 in a sequentially upward and downward position-limiting manner from front to back. The four L-shaped plates 6 are placed on top of the four fixed plates 12. The four first slides 9 are slidably connected to the first position-limiting grooves 7 on the L-shaped plates 6 in a sequentially upward and downward position-limiting manner. Elastic members 8 are connected between the tops of the four first slides 9 and the four L-shaped plates 6.

[0036] The bottom of the fixed plate 12 is slidably connected to four first pressing plates 10 in a front-to-rear limited manner. The four first pressing plates 10 are moved backward at the same time so that the four first pressing plates 10 press the front side of the wire.

[0037] Four second pressure plates 28 are pressed against the rear sides of the four first pressure plates 10. The bottoms of the four first slide plates 9 are pressed against the tops of the four second pressure plates 28. The four second pressure plates 28 are connected to four third slide plates 21 through third limiting grooves 29 at their bottoms. Four fixed rails 27 are fixedly connected to the vertical plate 3. The four third slide plates 21 are connected to the fixed rails 27 for vertical limiting sliding. Simultaneously moving the third slide plates 21 upward causes the second pressure plates 28 to press against the bottom of the wires, the first slide plates 9 to press against the rear sides of the wires, and the fixed plate 12 to press against the tops of the wires. This completely compresses the temperature sensor harness and connecting wires together, making welding easier. That is, four groups of first pressing plates 10, fixed plates 12, second pressing plates 28, and first slide plates 9 constitute four compactable openings. Moving the first pressing plates 10 and the third slide plates 21 allows multiple groups of temperature sensor harnesses and connecting wires placed in the four compactable openings to be compacted together.

[0038] Four wire through-holes 15 are provided on the riser 3. These four wire through-holes 15 are connected to the four compressible openings. That is, the temperature sensor harness is placed forward from one side of the compressible opening, so that the temperature sensor harness rests on the riser 3. The connecting wires are then inserted through the wire through-holes 15. The temperature sensor harness and connecting wires are then inserted from both sides to ensure they are more completely compressed together.

[0039] Four welding ports 13 are formed on the top of the fixing plate 12. These ports 13 are connected to four compressible openings. The compressed temperature sensor wiring harness and connecting wires are welded by the welding head through the welding ports 13, making it easier to weld and position the compressed temperature sensor wiring harness and connecting wires.

[0040] Embodiment 2: Based on embodiment 1, a technical means for automatically pressing the temperature sensor harness and the connecting wires is added.

[0041] Key References Figure 6-8 The left side of the vertical plate 3 is connected to a second slide plate 17 for forward and backward limited sliding movement via a second limiting slot 16. The bottom and top of the second slide plate 17 are respectively provided with third teeth 24 and second teeth 23. Four first connecting plates 11 are fixedly connected to the second slide plate 17, and the four first connecting plates 11 are respectively fixedly connected to the four first pressure plates 10.

[0042] A second rotating column 25 is rotatably connected to the vertical plate 3. A third gear 26 is fixedly connected to the outer wall of the second rotating column 25. The third gear 26 meshes with the third teeth 24. A motor 14 is fixedly mounted on the vertical plate 3. The power output end of the motor 14 is connected to the second rotating column 25.

[0043] The vertical plate 3 is rotatably connected to a first rotating column 20 . The outer wall of the first rotating column 20 is fixedly connected to a second gear 19 and a first gear 18 . The second gear 19 is meshed with the second teeth 23 .

[0044] Multiple fixed rails 27 are fixedly connected to the vertical plate 3. Four third slides 21 are slidably connected to the multiple fixed rails 27 in upper and lower limit positions. First teeth 22 are provided on one side of each of the four third slides 21, and the first teeth 22 mesh with the first gear 18. Starting the motor 14 automatically compresses the temperature sensor harnesses and connecting wires.

[0045] The rest of the structure of this embodiment is the same as that of the first embodiment.

[0046] Embodiment 3: Based on embodiment 2, a technical means for facilitating the placement of the temperature sensor harness and connecting wires is added.

[0047] Key References Figure 1 The bottom of the riser 3 is fixedly connected to the bottom plate 1, and the right side of the riser 3 is fixedly connected to the temperature sensor harness placement plate 2. The top left side of the bottom plate 1 is fixedly connected to the support plate 5, and the top of the support plate 5 is fixedly connected to the connection wire placement plate 4. That is, the connection wire placement plate 4 and the temperature sensor harness placement plate 2 are respectively placed on both sides of the riser 3.

[0048] In specific implementation, the temperature sensor wiring harness is first placed on the connecting wire placement plate 4. The multiple wires on the temperature sensor wiring harness are placed within the multiple, compactable, square-shaped structures formed by multiple sets of first pressure plates 10, fixed plates 12, second pressure plates 28, and first slide plates 9, and pressed against the vertical plate 3. Connecting wires are placed on the temperature sensor wiring harness placement plate 2 and inserted through the wire insertion opening 15. At this point, the power to the starting motor 14 engages the third gear 26 with the third teeth 24, causing the second slide plate 17 to move rearward. The second slide plate 17 then drives the first pressure plate 10 rearward via the first connecting plate 11. The second teeth 23 of the second slide 17 move backward and engage with the second gear 19, thereby rotating the first rotating column 20 and the first gear 18. At this time, the first gear 18 engages with the first teeth 22, causing the four third slides 21 to move upward. The third slides 21 press the second pressing plate 28 upward. That is, the first pressing plate 10 presses the front side of the temperature sensor harness and connecting wires, the second pressing plate 28 presses the bottom of the temperature sensor harness and connecting wires, the first slide 9 presses the rear side of the temperature sensor harness and connecting wires, and the fixing plate 12 presses the top of the temperature sensor harness and connecting wires. At this time, the temperature sensor harness and connecting wires are compressed, and then the welding head welds the compressed temperature sensor harness and connecting wires from the welding port 13.

[0049] The technical scope of the present invention is not limited to the contents of the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
