The fixing assembly includes a first fixing member 32 for fixing the positive electrode sheet, a second fixing member 33 for fixing the negative electrode sheet, and a third fixing member 34 for fixing the spring sheet. The first fixing member 32 is located on the side of the second fixing member 33, and the third fixing member 34 is located behind the second fixing member 33. The lower ends of the first fixing member 32, the second fixing member 33, and the third fixing member 34 are all elastically floatingly matched with the base 11. A first card slot 35 for placing the positive electrode sheet is provided above the first fixing member 32, and a card slot 35 for placing the positive electrode sheet is provided above the second fixing member 33. The negative electrode sheet has a second slot 36. Above the third fixture 34 is a third slot 37 for receiving a spring. A first step 39 is also provided at the front end of the third fixture 34. A fourth slot 38 with an adjustable gap is formed between the first step 39 and the second fixture 33. (The fourth slot 38 is the gap between the second and third fixtures 33, 34. This gap should be neither too large nor too small, and should be slightly larger than the thickness of the PTC. The first step 39 provides support for the PTC to prevent it from falling.) The PTC is placed in the fourth slot 38, sandwiched between the second and third fixtures 33, 34. PTC stands for PTC thermistor. The locking assembly is installed in the middle of the base 11, and the locking assembly is slidably locked with the first fixing member 32, the second fixing member 33, and the third fixing member 34. The clamping assembly is elastically installed at the rear of the base 11, and the clamping assembly is fixedly connected to the rear positioning member 23. The rear positioning member 23 is fixedly connected to the third fixing member 34. The size of the gap in the fourth slot is adjusted by tightening or loosening the clamping assembly; the clamping mechanism 41 includes a left clamping assembly and a right clamping assembly for installing carbon crystals. The left clamping assembly and the right clamping assembly are both installed above the base 11 and are respectively located on both sides of the positioning mechanism 21.

The base 11 is provided with a second stopper 47 for limiting the rotation range of the right clamping jaw 45. The second stopper 47 is located behind the right clamping jaw 45 to prevent the right clamping jaw 45 from swinging excessively during reset or due to excessive elastic force.

[0038] The positive electrode sheet and the negative electrode sheet are both connected to the carbon crystal through copper wire. When the robot is installing the positive electrode sheet and the negative electrode sheet, the carbon crystal is also installed in the left clamping jaw 42 and the right clamping jaw 45.

[0039] Figure 5 What is shown in the figure is a three-dimensional view of a rubber cover assembly machine equipped with the jig. The rubber cover assembly machine is provided with a turntable mechanism 52 for carrying and rotating the jig. The turntable mechanism 52 is preferably a circular turntable driven by a motor. The jig is driven to rotate by the turntable mechanism 52. The rubber cover assembly machine places various components on the jig and presses the rubber cover.

[0040] By interconnecting the above-mentioned components, a jig for assembling the motor rubber cover of this embodiment is assembled. The working process of the present invention is as follows: the jig rotates as the turntable mechanism 52 drives it, and the manipulator (the structure in the rubber cover assembly machine, which can adopt a clamping cylinder and other mechanisms) installs the spring piece, PTC, positive electrode sheet and negative electrode sheet in their respective corresponding slots on the jig, and at the same time places the carbon crystal on the clamping claw mechanism 41. Then the jig is driven to rotate by the turntable mechanism 52, and then the driving device (the structure in the rubber cover assembly machine, which can adopt a cylinder and other mechanisms) drives the pressure rod 314 to press the spring piece and PTC forward, and then the manipulator (the structure in the rubber cover assembly machine, which can adopt a clamping cylinder and other mechanisms) presses the rubber cover downward to the positioning mechanism 21, and then the rubber cover is fixed to the first fixing member 3 2. The second fixing member 33 and the third fixing member 34 are pressed downward, and the rubber cover is pressed into one with the spring piece, PTC, positive electrode sheet and negative electrode sheet. Then the driving device (the structure in the rubber cover assembly machine, which can adopt a cylinder or other mechanism) drives the locking rod 310 to lock the first fixing member 32, the second fixing member 33 and the third fixing member 34. Then the driving device (the structure in the rubber cover assembly machine, which can adopt a cylinder or other mechanism) pushes the left clamping jaw 42 and the right clamping jaw 45 on the jig to insert the carbon crystal into the rubber cover, completing the rubber cover installation process. The pressed rubber cover will be transported away, and then the jig will be pushed in the opposite direction by the driving device (the structure in the rubber cover assembly machine, which can adopt a cylinder or other mechanism) to release the locking rod 310 of the first fixing member 32, the second fixing member 33 and the third fixing member 34. The present invention, through the cooperation of the positioning mechanism 21, the fixing mechanism 31 and the clamping mechanism 41, can enable the positive electrode sheet, the negative electrode sheet, the PTC, the spring piece, the carbon crystal and other components to be stably and efficiently assembled into the rubber cover, thereby improving the yield rate and saving labor costs. The front positioning member 22 and the rear positioning member 23 in the positioning mechanism 21 of the present invention are both provided with an inclined surface 26 for guiding the downward pressure trajectory of the rubber cover. On the one hand, they play the role of guiding the downward pressure of the rubber cover, and on the other hand, they can play the role of preventing the rubber cover from being scratched. The left clamping jaw 42 and the right clamping jaw 45 of the present invention can clamp carbon crystals of different specifications, have strong adaptability, and are convenient for different usage scenarios.

[0041] The present invention also provides an operating method for a jig for assembling a motor rubber cover, comprising the following steps: S1, a manipulator installs the positive electrode sheet in the first slot, the negative electrode sheet in the second slot, the spring sheet and the PTC in the third slot, and the carbon crystal in the clamping mechanism; S2, a driving device drives the pressure rod forward to press the spring sheet and the PTC, and the manipulator presses the rubber cover downward into the positioning mechanism, completing the assembly process of the rubber cover and the spring sheet, the PTC, the positive electrode sheet, and the negative electrode sheet; S3, the first fixing member, the second fixing member, and the third fixing member are pressed downward by the pressed rubber cover, and the locking rod locks the descending first fixing member, the second fixing member, and the third fixing member; S4, the driving device pushes the left clamping member and the right clamping member in the clamping mechanism, installs the carbon crystals of the positive electrode sheet and the negative electrode sheet into the rubber cover, and completes the assembly process of the rubber cover.

[0042] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention.
