Then, the drive motor is started to rotate its output shaft, thereby driving the fixed shaft and the positioning rod to rotate, and driving the bidirectional lead screw to rotate at the same time.

When the slot 306 is separated from the block 106, the drive motor 6 is started to rotate its output shaft, thereby driving the fixed shaft 307 to rotate. Since the first driving gear 308 and the second driving gear 309 are fixedly installed on the outside of the fixed shaft 307, when the first driving gear 308 and the second driving gear 309 rotate, the driven gear 304 will be driven to rotate.

Therefore, the first driving gear 308 and the second driving gear 309 can be replaced by the different rotation speeds required by the driven gear 304.

In addition, the limiting sleeve 301 and the limiting slide 303 can slide, but the limiting sleeve 301 cannot rotate inside the limiting slide 303, and the outside of the positioning rod 305 and the inside of the mounting groove 310 have the same number of edges, so the positioning rod 305 can only slide but not rotate inside the mounting groove 310. In addition, the two support frames 4 can support the moving component 1, and the function of the fixed frame 5 is to support and install the drive motor 6.

At this time, the drive motor 6 is started to rotate its output shaft, thereby driving the fixed shaft 307 and the positioning rod 305 to rotate, and at the same time driving the bidirectional screw rod 104 to rotate. Since the bottoms of the two sides of the moving block 105 slide on the tops of the two limiting rails 101 respectively, they cannot detach from the outside of the limiting rails 101 while sliding. Under the rotation of the bidirectional screw rod 104, the two moving blocks 105 will be driven to move to the middle at the same time, or to both sides at the same time, thereby realizing the clamping operation.

The inner wall of the slide groove 202 is slidably connected with a slider 203, the top of the slider 203 is fixedly connected with a connecting shell 204, the inside of the connecting shell 204 is rotatably connected with a connecting block 206, the top of the connecting block 206 is fixedly connected with an adjusting screw 207, the top of the adjusting screw 207 is fixedly connected with an adjusting knob 208, the outer surface of the adjusting knob 208 is threadedly connected with the inner wall of the connecting groove 205, and ... The inner wall of the block 203 is rotatably connected with a connecting sleeve 210, one end of the connecting sleeve 210 is fixedly connected with an anti-dropping block 209, the anti-dropping block 209 is internally slidably connected with a connecting rod 211, the inner wall of the connecting sleeve 210 is provided with a limiting groove 213, the outer surface of the connecting rod 211 is fixedly connected with a limiting strip 212, the outer surface of the limiting strip 212 is slidably connected with the inner wall of the limiting groove 213, a fixing spring 214 is arranged between one end of the connecting rod 211 and the inner wall of one end of the connecting sleeve 210, and one end of the limiting sleeve 301 is connected with one of the limiting strips 212. One side of the anti-slip block 209 is fixedly connected, one end of the connecting rod 211 is fixedly connected to a clamping plate 215, two movable grooves 216 are provided inside the clamping plate 215, and connecting springs 217 are arranged inside the two movable grooves 216. Both ends of the two connecting springs 217 are fixedly connected to movable rods 218, and one end of each adjacent two movable rods 218 is fixedly connected with a positioning clamp 219. The two positioning clamps 219 are symmetrically arranged, and the two positioning clamps 219 are used to clamp the lithium battery motherboard to be assembled.

[0038] In this embodiment, when in use, the lithium battery motherboard to be assembled is clamped between the two clamping plates 215. When clamping, the positioning clamps 219 at both ends of the clamping plates 215 are pulled outward. When pulling out, the connecting spring 217 inside the movable groove 216 will be stretched. After adjusting the position of the lithium battery, the positioning clamps 219 are released. Under the rebound effect of the connecting spring 217, the two positioning clamps 219 will return to their original positions at the same time, thereby achieving the clamping and positioning of the lithium battery. The connecting rod 211 and the connecting sleeve 210 can be elastically connected by the fixing spring 214, so that the lithium battery will not be damaged when being clamped. At this time, the limit bar 212 is in the limit groove 213. When the driven gear 304 and the second driving gear 309 are meshed, the clamping plate 215 needs to be adjusted downward, and the adjusting screw 207 is driven to rotate inside the connecting groove 205 by means of the adjusting knob 208. When the adjusting screw 207 is rotated, the connecting block 206 rotates inside the connecting shell 204, thereby driving the slider 203 to slide inside the slide groove 202, and then adjusting the height of the slider 203, and finally achieving the purpose of adjusting the height of the clamping plate 215, so that the driven gear 304 and the second driving gear 309 are meshed and connected.

[0039] The method of use and working principle of the device are as follows: when in use, the lithium battery motherboard to be assembled is clamped between the two clamping plates 215. When clamping, the positioning clamps 219 at both ends of the clamping plates 215 are pulled outward. When pulling out, the connecting spring 217 inside the movable groove 216 will be stretched. After adjusting the position of the lithium battery, the positioning clamps 219 are released. Under the rebound effect of the connecting spring 217, the two positioning clamps 219 will return to their original positions at the same time, thereby achieving the clamping and positioning of the lithium battery. The connecting rod 211 and the connecting sleeve 210 can be elastically connected through the fixing spring 214, so that the lithium battery will not be damaged when being clamped. At this time, the limiting strip 212 slides inside the limiting groove 213, and the connecting rod 211 only The movable plate 215 is able to slide inside the connecting sleeve 210 but cannot rotate. When the driven gear 304 and the second driving gear 309 are meshed, the clamping plate 215 needs to be adjusted downward, and the adjusting screw 207 is driven to rotate inside the connecting groove 205 by means of the adjusting knob 208. When the adjusting screw 207 is rotated, the connecting block 206 rotates inside the connecting shell 204, thereby driving the slider 203 to slide inside the slide groove 202, and then adjusting the height of the slider 203, so that the driven gear 304 and the second driving gear 309 are meshed and connected. When in use, the electric push rod 311 is started to extend until the positioning rod 305 is extended to the block 106 and inserted into the slot 306, and the electric push rod 311 is started at the same time. The telescopic rod 302 is extended and retracted, so that the engagement between the driven gear 304 and the first driving gear 308 or the second driving gear 309 is disengaged. At this time, the driving motor 6 is started to rotate its output shaft, thereby driving the fixed shaft 307 and the positioning rod 305 to rotate, and at the same time driving the bidirectional screw rod 104 to rotate. Since the bottoms of the two sides of the moving block 105 slide on the tops of the two limiting rails 101 respectively, they cannot be detached from the outside of the limiting rails 101 while sliding. Under the rotation of the bidirectional screw rod 104, the two moving blocks 105 will be driven to move to the middle at the same time, or to both sides at the same time. When in use, the electric push rod 311 is started to shrink it. When shrinking, the positioning rod 305 will enter the installation groove 310 The interior of the electric telescopic rod 302 is shortened, so that the length between the positioning rod 305 and the fixed shaft 307 is shortened. When the card slot 306 is separated from the card block 106, the drive motor 6 is started to rotate its output shaft, thereby driving the fixed shaft 307 to rotate. Since the first driving gear 308 and the second driving gear 309 are fixedly installed on the outside of the fixed shaft 307, when the first driving gear 308 and the second driving gear 309 rotate, the driven gear 304 is driven to rotate. The electric telescopic rod 302 is started to be extended and retracted, so that the driven gear 304 can maintain meshing with the first driving gear 308 or the second driving gear 309, wherein the tooth distance of the first driving gear 308 is larger than that of the second driving gear 309. Therefore,The first driving gear 308 and the second driving gear 309 can be replaced by the different speeds required by the driven gear 304. Under the rotation of the driven gear 304, the clamping plate 215 can be driven to adjust the angle. In addition, the limit sleeve 301 and the limit slide 303 can slide, but the limit sleeve 301 cannot rotate inside the limit slide 303, and the number of edges of the outside of the positioning rod 305 and the inside of the installation groove 310 are the same, so the positioning rod 305 can only slide but not rotate inside the installation groove 310. In addition, the two support frames 4 can support the moving component 1, and the fixed frame 5 is used to support and install the drive motor 6, wherein the drive motor 6 uses a servo motor that can rotate forward and reverse. The servo motor has a high-precision encoder inside, which can accurately feedback the position, speed and other information of the motor. When the controller sends a forward speed or position command, the motor rotates forward, and when a reverse command is sent, the motor rotates reversely.
