[0054] Working principle of the present invention:

[0055] The present invention is provided with a battery processing assembly that can perform high-quality rolling processing on the battery. The battery is accurately positioned by a positioning mechanism and a pressing mechanism, and the battery is rolled using a rolling head with a plurality of rotatable rolling rollers 7, thereby achieving rolling processing while ensuring the quality of the battery. Figure 1 As shown, one end of the battery matches the positioning block 13, and part of the battery extends into the positioning groove 131 of the positioning block 13 to facilitate positioning and fixing the battery. In this embodiment, the battery is a cylindrical battery, and the positioning groove 131 is cylindrical.

[0056] In this embodiment, the switching lifting unit 15 of the loading switching mechanism can drive the switching track 16 to rise and fall, so as to match the forward conveyor line 2. The clamping fixtures 1 on the switching track 16 have all been placed with batteries that have been adjusted by the first distance adjustment mechanism; therefore, the clamping fixture 1 is moved and transported along the forward conveyor line 2 (from right to left), passing through the corresponding position of the battery processing assembly. In this embodiment, multiple battery processing assemblies are provided, and each battery processing assembly includes a positioning mechanism, a pressing mechanism and a rolling mechanism. The forward conveyor line 2 transports the clamping fixture 1 to the corresponding positioning mechanism and the rolling mechanism. Between the structures, the positioning mechanism prompts the positioning block 13 to match and fit one end of the battery of the clamping fixture 1 through the positioning Y-axis moving mechanism 12, and the pressing mechanism prompts the pressing block 4 to press the battery of the clamping fixture downward through the pressing lifting mechanism 21, and the rolling mechanism prompts the rolling head to match the other end of the battery of the clamping fixture 1 through the rolling Y-axis moving mechanism 6; in this embodiment, the positioning Y-axis moving mechanism 12, the rolling Y-axis moving mechanism 6, the pressing lifting mechanism 21, etc. can all be selected from linear modules, screw drives, cylinders or electric cylinders that can move linearly back and forth; the rolling drive unit 5 prompts the rolling head to match the other end of the battery of the clamping fixture 1 The pressure head performs a rolling process on the battery. In this embodiment, the inner diameter of the dust suction tube 9 near the battery end is larger than the inner diameter of the battery. A plurality of notches 11 are provided on the outer edge of the dust suction tube 9 near the battery end. Each notch 11 is rotatably provided with a rolling roller 7. Some rolling rollers 7 are located at the notch 11 of the dust suction tube 9. Therefore, the distance between the rolling roller 7 and the outer wall of the battery end is closer than the distance between the inner wall of the dust suction tube 9 and the outer wall of the battery end. When the rolling drive unit 5 drives the transmission shaft 10 to rotate, the rolling roller 7 rotates with the rotation of the base 8, and the rolling roller 7 and the base 8 are rotatably connected. Then, the hemming roller 7 contacts the outer wall of the battery end to perform hemming treatment on the outer wall of the battery end. The hemming roller 7 can rotate freely to improve the mobility and avoid rigid collision with the outer wall of the battery end. It effectively protects the battery during the hemming process and reduces pollution discharge. Particles and pollutants can be discharged through the dust suction pipe 9. The hemming roller 7 can block the gap 11 to discharge pollutants and ensure the rotation of the hemming roller 7. There is a gap between the gap 11 and the hemming roller 7, and there is a gap between the dust suction pipe 9 and the battery to ensure gas flow and facilitate the dust suction pipe 9 to extract pollutants and polluted gases. The battery after the hemming treatment is completed (through the clamping fixture 1) is transported along the forward conveying line 2. The swingable first detection unit 20 can detect the battery after the hemming treatment. Multiple first detection units 20 can be selected to detect the battery to achieve multi-faceted detection. In this embodiment, three first detection cameras are selected to detect the battery after the hemming treatment. The three first detection cameras are set at different angles and the detection angle of the first detection camera can be adjusted individually by swinging. As shown in the attached figure Figure 3 、 4 5, this embodiment has three notches 11, three edge rollers 7, and three bearings 19; Figure 6The direction of the arrow in the figure is the conveying direction of the clamping jig 1, that is, the conveying direction of the forward conveyor line 2 and the reverse conveyor line 3. The loading switching mechanism, the forward conveyor line 2, the unloading switching mechanism, and the reverse conveyor line 3 constitute a circulating conveyor line, which can be used for the circular conveying of the clamping jig 1, and can meet the needs of continuous rolling processing of cylindrical batteries. During the rolling process, the rolling roller 7 generates a rolling motion on the edge of the cylindrical battery due to the action of the rolling bearing 19, which does not damage the cylindrical battery and reduces the rigid collision between the rolling roller 7 and the cylindrical battery. In this embodiment, the rolling drive unit 5 can use a motor to drive the transmission shaft 10 to rotate through a synchronous belt, thereby driving the base 8 and the rolling roller 7 on the base 8 to rotate.

[0057] The inspected batteries are transported to the bottom of the blanking clamping unit 18, that is, the batteries mounted on the clamping fixture 1 are placed on the switching track 16 of the blanking switching mechanism after processing. The blanking flipping mechanism of the blanking clamping unit 18 transfers the processed batteries for blanking through the blanking Y-axis moving mechanism and the blanking lifting mechanism.

[0058] The loading clamping unit 17 includes a loading flipping mechanism, a loading lifting mechanism for raising and lowering the loading flipping mechanism, and a loading Y-axis moving mechanism for adjusting the loading lifting mechanism's displacement along the Y-axis. The unloading clamping unit 18 includes a unloading flipping mechanism, a unloading lifting mechanism for raising and lowering the unloading flipping mechanism, and a unloading Y-axis moving mechanism for adjusting the unloading lifting mechanism's displacement along the Y-axis. The loading flipping mechanism includes a loading jaw and a loading flipping drive unit for flipping the loading jaw. The unloading flipping mechanism includes a loading jaw and a loading flipping drive unit for flipping the loading jaw. The unloading flipping mechanism includes a unloading jaw and a unloading flipping drive unit for flipping the loading jaw. The flipping drive unit flips the loading jaw holding the battery, and the loading Y-axis moving mechanism drives the loading jaw to place the battery on the corresponding clamping fixture 1. The structural principle of the unloading clamping unit 18 is consistent with that of the loading clamping unit 17 , and therefore, a detailed description thereof will not be repeated. Figure 1 In the figure, A is a cylindrical battery.
