In addition, various specific examples of processes and materials are provided in this application, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0032] This application provides a welding fixture for a small-volume flat wire motor stator. (See reference...) Figure 1 and Figure 2 The welding fixture for the stator of a small-volume flat wire motor includes a welding clamping mechanism 10, a disc-shaped positioning device 20 with its bottom horizontally arranged, and an annular fixing seat 30 arranged above the positioning device for fixing the welding clamping mechanism.

[0033] The welding clamping mechanism 10 includes a base plate 101, a cover plate 102, and a V-shaped welding chuck 103. The base plate 101 is fixed on a circular fixed seat 30. The non-clamping end of the V-shaped welding chuck 103 is embedded in a reserved groove in the base plate 101. The cover plate 102 is disposed on the base plate 101 and can slide relative to the base plate 101. The head of the cover plate 102 is provided with two clamping members 40 with a certain gap for clamping the clamping end of the V-shaped welding chuck 103.

[0034] In this embodiment, simply pushing the cover plate 102 forward relative to the base plate 101 causes the two clamping members 40 on the head of the cover plate 102 to move forward and clamp the V-shaped welding chuck 103, thereby clamping the solder joint (flat copper wire solder joint). When it is necessary to loosen the solder joint, simply pull the cover plate 102 backward relative to the base plate 101. The two clamping members 40 on the head of the cover plate 102 will then move backward and loosen the V-shaped welding chuck 103, thereby loosening the solder joint (flat copper wire solder joint).

[0035] In this embodiment of the application, if the V-shaped welding chuck 103 needs to be replaced, it can be replaced simply by removing the cover plate 102, which is convenient and quick. In addition, the V-shaped welding chuck 103 has a low cost, so the replacement cost is relatively low.

[0036] The V-shaped welding chuck 103 in this embodiment of the application can be used more flexibly due to its slender design.

[0037] In some embodiments, the positioning device 20 includes a disc-shaped positioning disk 201 with its bottom horizontally disposed, and a circular boss 202 disposed at the center of the positioning disk for positioning the stator of the flat wire motor, wherein an annular fixing seat 30 is disposed on the positioning disk 201.

[0038] In some embodiments, the number of welding clamping mechanisms 10 is multiple, and the multiple welding clamping mechanisms 10 are arranged circumferentially on the annular fixing seat 30 at preset intervals.

[0039] It should be noted that the number of welding clamping mechanisms 10 is not specifically limited here, and those skilled in the art can set it according to the actual situation (actual product).

[0040] In some embodiments, the stator welding fixture for small-volume flat wire motors also includes two fixing members 50; the base plate 101 is provided with two base plate waist holes, and the two fixing members 50 pass through the two base plate waist holes to fix the base plate 101 on the annular fixing seat 30, wherein one fixing member 50 passes through one base plate waist hole; the cover plate 102 is provided with two cover plate waist holes at positions corresponding to the two base plate waist holes, and the two fixing members 50 pass through the two cover plate waist holes, and the cover plate 102 can slide relative to the base plate 101 through the two cover plate waist holes and the two fixing members 50.

[0041] Specifically, the fastener 50 passes through both the bottom plate waist hole and the cover plate waist hole. The fastener 50 is used to fix the bottom plate 101 on one hand, and to allow the cover plate 102 to maintain linear movement relative to the bottom plate 101 on the bottom plate 101 without detaching from the bottom plate 101 on the other hand.

[0042] In some embodiments, the annular fixing base 30 is provided with an annular groove, and the base plate 101 is fixed in the annular groove.

[0043] The circular groove facilitates the positioning of the base plate 101 and also helps to better fix the base plate 101.

[0044] In some embodiments, the fastener 50 is a bolt.

[0045] In some embodiments, the stator welding fixture for small-volume flat wire motors further includes a drive mechanism for driving the cover plate 102 to slide relative to the base plate 101, the drive mechanism being connected to the cover plate 102.

[0046] It should be noted that this application also supports the use of manual pushing to slide the cover plate 102 relative to the base plate 101.

[0047] In some embodiments, the drive mechanism is a cylinder or a servo motor.

[0048] It should be noted that the driving mechanism is not limited to cylinders or servo motors; any mechanism capable of driving the cover plate 102 to slide relative to the base plate 101 is acceptable, and will not be listed here.

[0049] In some embodiments, the clamping element 40 is a cylindrical pin.

[0050] It should be noted that the clamping part 40 is not limited to a cylindrical pin; it can be a similar contoured part, etc. Any part that can achieve the same effect is acceptable, and no specific limitation is made here.

[0051] In some embodiments, the V-shaped welding chuck 103 is made of a metal with good electrical conductivity.

[0052] In summary, the small-volume flat wire motor stator welding fixture provided in this application has the following advantages: ① easy installation; ② small size, requiring less operating space compared to circumferential clamping welding fixtures; ③ lower cost, and quick replacement of welding chucks; ④ more perfect compatibility with irregularly distributed weld points in narrow spaces.

[0053] In summary, the small-volume flat wire motor stator welding fixture provided in this application includes a welding clamping mechanism 10, a disc-shaped positioning device 20 horizontally positioned at the bottom, and an annular fixing seat 30 above the positioning device for fixing the welding clamping mechanism. The welding clamping mechanism 10 includes a base plate 101, a cover plate 102, and a V-shaped welding chuck 103. The base plate 101 is fixed on the annular fixing seat 30. The non-clamping end of the V-shaped welding chuck 103 is embedded in a reserved groove in the base plate 101. The cover plate 102 is disposed on the base plate 101 and can slide relative to the base plate 101. The head of the cover plate 102 is provided with two clamping members 40 with a certain gap for clamping the clamping end of the V-shaped welding chuck 103.
