To achieve precise welding of the cell tabs and connecting pieces, spot welding equipment for vacuum cleaner lithium battery processing is typically used to complete the series, parallel, or series-parallel combinations of cells.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figures 1-4 and Figures 7-9 As shown, the present invention provides a technical solution: a spot welding device for processing lithium batteries for vacuum cleaners, comprising a device body 1, a lithium battery body 3 and two connecting pieces 4, wherein an auxiliary mechanism 2 is provided on the device body 1; The auxiliary mechanism 2 includes a sliding plate 201, a sliding groove 202, a first motor 203, and a cylindrical hole 210. A threaded rod 204 is installed at the output end of the first motor 203. A placement groove 205 is formed at the top of the sliding plate 201, and an installation groove 206 is formed at the bottom of the inner wall of the placement groove 205. A pressure sensor 207 is installed inside the installation groove 206. A rectangular plate 208 is positioned above the first motor 203, and a laser rangefinder sensor 209 is installed at the top of the rectangular plate 208. A driver 211 is arranged around the first motor 203. Fixing brackets 212 are fixed on both sides of the sliding plate 201. Each of the following is a description of the components: Electric push rods 213 are mounted on the top of each component; a mounting bracket 214 is mounted on one end of the telescopic end of each electric push rod 213; two symmetrical second motors 215 are installed inside each mounting bracket 214; a connecting plate 216 is mounted on the output end of each second motor 215; a rubber pad 217 is adhered to the bottom of each connecting plate 216; a first telescopic plate 218 is mounted on the front surface of the sliding plate 201; a second telescopic plate 219 is mounted on the rear surface of the sliding plate 201; one end of a threaded rod 204 is threaded through the rear surface of the sliding plate 201 and rotatably embedded in the inner wall of the slide groove 202; each electric push rod... One end of the telescopic end of 213 moves through the top of each fixed frame 212. The sliding plate 201 is slidably connected inside the slide groove 202. The opposite ends of the first telescopic plate 218 and the second telescopic plate 219 are respectively installed on the front surface of the inner wall of the slide groove 202 and the rear surface of the inner wall of the slide groove 202. The cylindrical hole 210 is located directly in front of the detection end of the laser rangefinder 209. The four second motors 215 are divided into two groups. The output end of each group of second motors 215 moves through the bottom of the inner wall of each mounting frame 214. Each group of second motors 215 and each electric push rod 213 are electrically connected to the driver 211. The motor 203 and the driver 211 are both installed inside the housing 102. One end of the threaded rod 204 moves through the inner wall surface of the housing 102 and the surface of the pad 105 in sequence. The laser range sensor 209, the pressure sensor 207, the first motor 203 and the driver 211 are all electrically connected to the controller 104. The slide groove 202 is opened on the top of the pad 105. The cylindrical hole 210 is opened on the inner wall surface of the housing 102. The rectangular plate 208 is fixed on the inner wall surface of the housing 102. The lithium battery body 3 is located inside the placement slot 205. The two connecting pieces 4 are respectively located in the two grooves on the top of the lithium battery body 3.

[0022] In this embodiment, during use, the controller 104 is first turned on, and the pressure threshold and distance threshold are set. Then, the pressure sensor 207 and the laser rangefinder 209 are activated through the controller 104. Next, the two connecting pieces 4 are placed on the two grooves on the top of the lithium battery body 3, respectively. Then, the lithium battery body 3 with the connecting pieces 4 is placed inside the placement slot 205. At this time, the controller 104 will determine whether the lithium battery body 3 is placed inside the placement slot 205 by using the received pressure data (detected by the pressure sensor 207) and the pre-set pressure threshold. When the controller 104 determines that the lithium battery body 3 is placed inside the placement slot 205, the controller 104 will simultaneously start the two sets of second motors 2 through the driver 211. 15. At this point, both sets of second motors 215 will drive the corresponding connecting plates 216 to rotate via the corresponding mounting brackets 214. The rotating connecting plates 216 will drive the corresponding rubber pads 217 to rotate. When each connecting plate 216 has rotated 90 degrees, the controller 104 will simultaneously shut down both sets of second motors 215 via the driver 211. Subsequently, the controller 104 will simultaneously start two electric push rods 213 via the driver 211. At this point, both started electric push rods 213 will drive the corresponding rubber pads 217 to move vertically downward via the corresponding fixing brackets 212, the corresponding mounting brackets 214, the corresponding second motors 215, and the corresponding connecting plates 216. When the rubber pads 217 have moved to the point where they can no longer move... At this time, the controller 104 will simultaneously close the two electric push rods 213 via the driver 211. Simultaneously, the four rubber pads 217 will press down the two connecting pieces 4 on the lithium battery body 3. Then, the controller 104 will directly start the first motor 203. The started first motor 203 will then drive the sliding plate 201 to move horizontally towards the first motor 203 via the threaded rod 204 and the sliding groove 202. The moving sliding plate 201 will cause all its components to move horizontally. Simultaneously, the moving sliding plate 201 will drive the first telescopic plate 218 to stretch and the second telescopic plate 219 to compress via the sliding groove 202. At the same time, the activated laser rangefinder 209 will move through the rectangular plate 208 and the cylindrical hole 210. The system continuously monitors the distance between the rear surface of the sliding plate 201 and its detection end, and transmits the detected distance data to the controller 104. The controller 104 compares the received distance data with a pre-set distance threshold. When the detected distance data is greater than the pre-set distance threshold, the controller 104 restarts the first motor 203. When the detected distance data is the same as the pre-set distance threshold, the first welding point on the lithium battery body 3 and the connecting piece 4 is directly below the bottom of the welding head 114. At the same time, the controller 104 directly shuts down the first motor 203. Subsequently, the controller 104 performs spot welding on the first welding point between the connecting piece 4 and the lithium battery body 3 through the device body 1.By using the first telescopic plate 218 and the second telescopic plate 219, it is possible to prevent welding slag and other impurities generated during the spot welding process from falling into the interior of the slide 202 and affecting the subsequent movement of the sliding plate 201. Then, the controller 104 will start the first motor 203, driving the lithium battery body 3 and the connecting piece 4 to continue moving towards the first motor 203 until the second welding point on the lithium battery body 3 and the connecting piece 4 is exactly below the bottom of the welding head 114. After that, the controller 104 will continue to perform spot welding operations on the second welding point on the lithium battery body 3 and the connecting piece 4 through the device body 1. Then the controller 104 will... 4. Following the above operating steps, spot welding is performed on the remaining welding points on the connecting piece 4 and the lithium battery body 3. When the spot welding operation is completed on the lithium battery body 3 and its connecting piece 4, the controller 104 will use the first motor 203, threaded rod 204, and sliding groove 202 to reset the sliding plate 201 to its original position. Subsequently, the controller 104 will use the fixing bracket 212, electric push rod 213, mounting bracket 214, second motor 215, and connecting plate 216 to reset the rubber pad 217 to its original position. Then, the lithium battery body 3, after the spot welding operation is completed, can be removed from the inside of the placement groove 205.

[0023] Example 2: According to Figures 1-7 and Figure 9 As shown, the device body 1 includes a base 101. A housing 102 and a pad 105 are fixed to the top of the base 101. A cover 103 is installed at the opening of the housing 102. A controller 104 is installed on the inner wall surface of the housing 102. A spot welding machine 106 is installed inside the housing 102. A shell 107 is fixed to the front surface of the housing 102. A hydraulic rod 108 is installed on the top of the shell 107. An L-shaped plate 109 is installed at one end of the telescopic end of the hydraulic rod 108. Four connecting blocks 110 are fixed to the front surface of the L-shaped plate 109. Limiting blocks 113 are fixed on both sides of the L-shaped plate 109. Two sliding holes 111 are opened on the inner front surface of the shell 107. Two symmetrical limiting grooves 112 are opened on the inner wall. Welding heads 114 are fixed between the front surfaces of four connecting blocks 110. The operating end of the controller 104 moves through the front surface of the inner wall of the housing 102. The four connecting blocks 110 are divided into two groups, and each group of connecting blocks 110 is movably sleeved inside each sliding hole 111. Each limiting block 113 is slidably connected inside each limiting groove 112. The welding head 114 is electrically connected to the spot welding machine 106. The hydraulic rod 108 and the spot welding machine 106 are both electrically connected to the controller 104. The L-shaped plate 109 is movably sleeved inside the housing 107. The two connecting pieces 4 are respectively located at the two grooves on the top of the lithium battery body 3.

[0024] In this embodiment, when the first welding point on the lithium battery body 3 and the connecting piece 4 is directly below the bottom of the welding head 114, the controller 104 will directly start the spot welding machine 106 and the hydraulic rod 108. The activated hydraulic rod 108 will then drive the L-shaped plate 109 to move vertically downwards via the housing 107, the limiting block 113, and the limiting groove 112. The vertically moving L-shaped plate 109 will then drive both sets of connecting blocks 110 to move vertically downwards via the two sliding holes 111. Simultaneously, the two sets of vertically moving connecting blocks 110 will drive the welding head 114 to move vertically downwards. When the bottom of the welding head 114 contacts the connecting piece 4, the welding head 114 will perform spot welding on the first welding point between the connecting piece 4 and the lithium battery body 3 via the spot welding machine 106. At the same time, the controller 104 will activate the spot welding machine 106 and the hydraulic rod 108, housing 106, and the connecting head 106. 107, L-shaped plate 109, connecting block 110, sliding hole 111, limiting groove 112, and limiting block 113 drive the welding head 114 to move vertically upward. Then, the controller 104 will drive the lithium battery body 3 and connecting piece 4 to move closer to the housing 102 through the auxiliary mechanism 2 until the second welding point on the lithium battery body 3 and connecting piece 4 is directly below the bottom of the welding head 114. Then, the controller 104 will continue to start the spot welding machine 106 and hydraulic rod 108 to spot weld the second welding point between the connecting piece 4 and the lithium battery body 3. After that, the controller 104 will operate according to the above steps to spot weld the remaining welding points between the connecting piece 4 and the lithium battery body 3. When the spot welding operation of the lithium battery body 3 and its connecting piece 4 is completed, the lithium battery body 3 that has completed the spot welding operation can be directly removed.

[0025] The usage and working principle of this device are as follows: First, turn on the controller 104 and set the pressure threshold and distance threshold. Then, activate the pressure sensor 207 and laser rangefinder 209 via the controller 104. Next, place the two connecting pieces 4 on the two grooves on the top of the lithium battery body 3. Then, place the lithium battery body 3 with the connecting pieces 4 inside the placement slot 205. At this time, the controller 104 will determine whether the placement slot 205 contains a lithium battery body 3 by using the received pressure data (detected by the pressure sensor 207) and the pre-set pressure threshold. When the controller 104 determines that the placement slot 205 contains a lithium battery body 3, the controller 104 will then activate the driver 211. When the two sets of second motors 215 are started, both sets of second motors 215 will drive the corresponding connecting plates 216 to rotate through the corresponding mounting brackets 214. The rotating connecting plates 216 will drive the corresponding rubber pads 217 to rotate. When each connecting plate 216 has rotated 90 degrees, the controller 104 will simultaneously shut down the two sets of second motors 215 through the driver 211. Then, the controller 104 will simultaneously start the two electric push rods 213 through the driver 211. At this time, the two started electric push rods 213 will drive the corresponding rubber pads 217 to move vertically downward through the corresponding fixing brackets 212, the corresponding mounting brackets 214, the corresponding second motors 215 and the corresponding connecting plates 216. When the rubber pads 217 rotate 90 degrees, the controller 104 will simultaneously shut down the two sets of second motors 215 through the driver 211. When all 17 have moved to their maximum position, the controller 104 will simultaneously shut off both electric push rods 213 via the driver 211. At the same time, the four rubber pads 217 will press down on the two connecting pieces 4 on the lithium battery body 3. Then, the controller 104 will directly start the first motor 203. The started first motor 203 will then drive the sliding plate 201 to move horizontally towards the first motor 203 via the threaded rod 204 and the sliding groove 202. The moving sliding plate 201 will cause all its components to move horizontally. Simultaneously, the moving sliding plate 201 will drive the first telescopic plate 218 to stretch and the second telescopic plate 219 to compress via the sliding groove 202. At the same time, the laser rangefinder 209 will be activated. The distance data between the rear surface of the sliding plate 201 and its detection end is detected in real time through the rectangular plate 208 and the cylindrical hole 210. The detected distance data is transmitted to the controller 104. The controller 104 compares the received distance data with a pre-set distance threshold. When the detected distance data is greater than the pre-set distance threshold, the controller 104 will continue to start the first motor 203. When the detected distance data is the same as the pre-set distance threshold, the first welding point on the lithium battery body 3 and the connecting piece 4 is exactly below the bottom of the welding head 114. At the same time, the controller 104 will directly shut down the first motor 203. Subsequently, the controller 104 will directly start the spot welding machine 106 and the hydraulic rod 108.At this time, the activated hydraulic rod 108 will drive the L-shaped plate 109 to move vertically downward through the housing 107, the limiting block 113, and the limiting groove 112. The vertically moving L-shaped plate 109 will drive both sets of connecting blocks 110 to move vertically downward through the two sliding holes 111. At the same time, the two sets of connecting blocks 110 will drive the welding head 114 to move vertically downward. When the bottom end of the welding head 114 contacts the connecting piece 4, the welding head 114 will then pass through the spot welding machine 106 to weld the connecting piece 4 to the lithium... The first welding point of the battery body 3 is spot-welded. At this time, the first telescopic plate 218 and the second telescopic plate 219 prevent welding slag and other impurities generated during the spot welding process from falling into the sliding groove 202 and affecting the subsequent movement of the sliding plate 201. At the same time, the controller 104 will drive the welding head 114 to move vertically upward through the hydraulic rod 108, the housing 107, the L-shaped plate 109, the connecting block 110, the sliding hole 111, the limiting groove 112 and the limiting block 113. At the same time, the controller 104 will activate The first motor 203 is activated, causing the lithium battery body 3 and the connecting piece 4 to continue moving closer to the first motor 203 until the second welding point on the lithium battery body 3 and the connecting piece 4 is directly below the bottom of the welding head 114. Then, the controller 104 will continue to activate the spot welding machine 106 and the hydraulic rod 108 to perform spot welding on the second welding point between the connecting piece 4 and the lithium battery body 3. Next, the controller 104 will operate according to the above steps to complete the remaining welding on the connecting piece 4 and the lithium battery body 3. The spot welding operation is performed. When the lithium battery body 3 and its connecting piece 4 are spot welded, the controller 104 uses the first motor 203, threaded rod 204, and sliding groove 202 to reset the sliding plate 201 back to its original position. Then, the controller 104 uses the fixing bracket 212, electric push rod 213, mounting bracket 214, second motor 215, and connecting plate 216 to reset the rubber pad 217 back to its original position. Finally, the lithium battery body 3, after the spot welding operation, can be removed from the placement groove 205.
