[0035] Example 1: Reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a HJT battery cleaning device, which includes a support assembly 100, a feeding assembly 200 and a cleaning assembly 300, wherein the support assembly 100 includes a mounting frame 101, a baffle 102 arranged opposite to the mounting frame 101, a turntable 103 arranged on the side wall of the mounting frame 101, a first motor 104 connected to the turntable 103, and a second motor 105 arranged on the turntable 103; the feeding assembly 200 is arranged on the turntable 103, including a rotating rod 201 arranged in the center of the turntable 103, slideways 202 symmetrically arranged on both sides of the turntable 103, a transmission rod 203 arranged in the slideway 202, a slider 204 connected to the transmission rod 203, and semi-rotating motors 105 respectively arranged on the slider 204. A gear 205 and a fixture 206 fixed on the half gear 205, a worm gear 207 arranged on the transmission rod 203, and a starting tooth groove 208 arranged on the side wall of the slide 202; and a cleaning component 300, which is arranged opposite to the feeding component 200, including a nozzle 301a arranged on the top of the baffle 102, a base 301 arranged parallel to the baffle 102, a circulating trolley 302 arranged on the base 301, a fixed seat 303 arranged on the circulating trolley 302, a positioning rod 304 slidably connected to the fixed seat 303, a gear 305 rotatably connected to the fixed seat 303, a brush 306 connected to the gear 305, a tooth groove 307 arranged on the base 301 and a positioning groove 308 embedded in cooperation with the positioning rod 304.

[0036] The rotating disk 103 is rotatably connected to the mounting frame 101, the first motor 104 is fixedly arranged on the side wall of the mounting frame 101, and the output shaft of the first motor 104 is fixedly connected to the rotating disk 103. The rotating rod 201 is arranged at the center of the rotating disk 103, the rotating rod 201 is rotatably connected to the rotating disk 103, worms 201a are symmetrically arranged at both ends of the rotating rod 201, the worm wheel 207 is respectively engaged with the two worms 201a, and the output shaft of the second motor 105 is fixedly connected to the rotating rod 201. The transmission rod 203 extends into the slideway 202, the transmission rod 203 is rotatably connected to the slideway 202, the cross section of the slider 204 is the same as the inner wall shape of the slideway 202, the slider 204 is slidably connected to the slideway 202, each slideway 202 is provided with a slider 204, and the slider 204 is also connected to the transmission rod 203 by thread. The slider 204 located on one side of the turntable 103 is rotatably connected to a clamp 206, and the slider 204 located on the other side of the turntable 103 is rotatably connected to the half gear 205. The half gear 205 is fixedly provided with a matching clamp 206, and the starting tooth groove 208 and the half gear 205 are arranged on the same side, and the half gear 205 can mesh with the starting tooth groove 208.

[0037] During use, in order to fix the battery, the battery is placed in the clamp 206. The loading and subsequent unloading processes can use a mechanical arm to automatically install the battery. After the clamp 206 clamps the battery, in order to put the battery plug into the cleaning area, the second motor 105 can be started. The output shaft of the second motor 105 drives the rotating rod 201 to rotate, and the worms 201a at both ends of the rotating rod 201 rotate synchronously, and the worm 201a is meshed with a worm gear 207, so that the second motor 105 can drive the worm gear 207 to rotate, that is, drive the transmission rod 203 to rotate. The slider 204 is connected to the transmission rod 203 through a thread. The rotation of the thread of the transmission rod 203 can drive the slider 204 to move forward along the slide 202, that is, the second motor 105 can make the two sliders 204 slide along the slide 202. During the movement, the battery is in a vertical state, and the plug is located at the top of the battery. When the slider 204 moves, the half gear 205 on the slider 204 gradually approaches the starting tooth groove 208. When the half gear 20 When the half gear 205 is engaged with the starting tooth groove 208, the half gear 205 will rotate according to the starting tooth groove 208, driving the clamp 206 on the half gear 205 to rotate, changing the battery clamped by the clamp 206 from vertical to horizontal, and the battery plug will become the front end, so that it can be inserted into the through hole 102a for cleaning. Resetting only requires the second motor 105 to reverse, and the half gear 205 will reset through the starting tooth groove 208, so that the battery plug will leave the through hole 102a, and then the first motor 104 will be started to rotate the entire turntable 103 around the mounting frame 101 by 180°, so that the battery plug can be turned over, so that the brush 306 can clean the upper and lower surfaces. When the battery plug is placed in the cleaning area, it only needs to repeat the above operation, that is, first place the battery horizontally, send the plug into the through hole 102a, then retract the battery, turn the whole 180°, and the bottom surface of the original battery plug becomes the top surface, and then send it into the through hole 102a again. After cleaning is completed, the next battery is replaced by the robot arm, and the cycle continues.

[0038] Example 2: Reference Figures 1 to 8, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that: the baffle 102 is provided with a through hole 102a, and the battery plug can be inserted into the through hole 102a; the base 301 is provided with a circulation groove 301b, and the circulation trolley 302 is arranged in the circulation groove 301b, and the fixed seat 303 is fixedly connected with the circulation trolley 302, and the positioning rod 304 is arranged in the fixed seat 303, and the positioning rod 304 extends out of the top of the fixed seat 303, and the positioning rod 304 can slide in the fixed seat 303, and the positioning rod 304 is also fixedly connected with a buckle 304a, and the gear 305 is embedded in the buckle 304a. The brush 306 is fixedly connected with the gear 305, and the brush 306 is slidably connected with the gear 305 and the fixed seat 303, and the horizontal height of the brush 306 is above the through hole 102a. The tooth groove 307 can mesh with the gear 305, and the length of the tooth groove 307 is the same as the width of the through hole 102a. The base 301 is provided with brackets on both sides, and the positioning groove 308 is centrally symmetrically arranged on the brackets. The positioning groove 308 includes an inclined surface 308a and an embedded groove 308b. The positioning rod 304 can be inserted into the embedded groove 308b, and the inclined surface 308a guides the embedded groove 308b.

[0039] Compared with Example 1, in order to clean the battery plug, after the plug is placed in the through hole 102a, the baffle 102 can block the cleaning process to prevent the liquid from contacting the battery, and the circulation trolley 302 is set to move in a continuous cycle from left to right and from right to left in the circulation groove 301b. In the initial state, the circulation trolley 302 is located at the leftmost end of the base 301, and the positioning rod 304 is located in the embedding groove 308b. The circulation trolley 302 moves to the rightmost end with the fixed seat 303. When the gear 305 passes through the tooth groove 307, the gear 305 meshes with the tooth groove 307 to rotate the gear 305, driving the brush 306 to rotate, and cooperate with the cleaning liquid in the nozzle 301a at the top of the baffle 102 to clean the top surface of the battery plug in the through hole 102a. After the brush 306 passes the top surface of the latch, the gear 305 is disengaged from the tooth groove 307, the positioning rod 304 contacts the inclined surface 308a in the positioning groove 308 at the rightmost end, the fixed seat 303 continues to move, and the positioning rod 304 enters the embedded groove 308b along the inclined surface 308a, that is, the positioning rod 304 slides backward in the fixed seat 303, and the buckle 304a drives the gear 305 to move backward, so that the gear 305 and the tooth groove 307 are staggered, and the cycle is small. When the trolley 302 moves from the rightmost end to the left, the gear 305 does not mesh with the tooth groove 307, and the brush 306 does not rotate. In the process of the circulating trolley 302 moving to the left, the brush 306 and the nozzle 301a do not work. The battery pin can be retracted and turned over by this gap. The battery pin is turned over so that the original bottom surface of the pin becomes the top surface and is put back into the through hole 102a. The positioning rod 304 is introduced into the initial embedding groove 308b through the inclined surface 308a at the leftmost end. The gear 305 slides in the fixing seat 303 toward the baffle 102 and is on the same horizontal line with the tooth groove 307, returning to the initial state, and then the above steps are repeated again to clean the top surface of the pin. Through the above scheme, the brush 306 and the nozzle 301a can be paused when the battery is turned over, so that the surface of the brush 306 can be evenly coated, and only part of the surface of the brush 306 will be used heavily, which will make the cleaning effect unsatisfactory.

[0040] The production wastewater left over from this cleaning can be treated by the following steps:

[0041] S1: Collect wastewater and introduce it into the collection tank;

[0042] S2: Pump concentrated alkali into the collection tank for adjustment, and after homogenization and uniformity, pump it into the concentrated alkali reaction precipitation tank for precipitation;

[0043] S3: discharge concentrated alkaline wastewater, and transport the precipitated sludge after dehydration;

[0044] S4: Pour into the degassing tank and blow off to obtain the final wastewater, which will be discharged after meeting the standards.

[0045] The remaining structures are the same as those of Example 1.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
