The first gear 222 is rotatably arranged on the first support seat 28 through the first transmission shaft 224. The first motor 221 is in transmission connection with the first transmission shaft 224. Specifically, the output shaft of the first motor 221 and the end of the first transmission shaft 224 are provided with mutually meshing bevel gears to realize the transmission connection between the first motor 221 and the first transmission shaft 224. The first rack 223 is meshed with the first gear 222. The first rack 223 is connected to at least one group of manipulator support seats 21. The first rack 223 is slidably connected to the bracket or the first support seat 28. The operation of the first motor 221 drives the first transmission shaft 224 to rotate, thereby rotating the first gear 222. The rotation of the first gear 222 moves the first rack 223, thereby causing multiple groups of manipulator support seats 21 to move synchronously along the X-axis direction.

[0061] Furthermore, the first gear 222 , the first rack 223 , and the first transmission shaft 224 are each provided in pairs, and the first gear 222 and the first rack 223 are respectively located at both ends of the first support seat 28 along the Y-axis direction, thereby improving the stability of the synchronous movement of multiple groups of robot support seats 21 .

[0062] In this embodiment, a lifting support seat 23 and a first lifting mechanism 24 are arranged on each group of manipulator support seats 21, and the first lifting mechanism 24 includes a first lifting motor 241, a first lifting gear 242, a first lifting rack 243, and a first lifting rail 244. The first lifting motor 241 is arranged on the manipulator support seat 21, and the first lifting motor 241 is connected to the first gear 222 through an output shaft, and the output shaft is rotatably connected to the manipulator support seat 21, the first lifting rack 243 is fixedly connected to the first lifting rail 244, the first lifting rail 244 is slidably connected to the manipulator support seat 21, and the lower end of the first lifting rail 244 is fixedly connected to the lifting support seat 23, the first lifting rack 243 is meshed with the first lifting gear 242, the first lifting motor 241 is running, driving the first lifting gear 242 to rotate, and the first lifting gear 242 rotates to make the first lifting rack 243 move up and down (i.e. move along the Y-axis direction), so that the lifting support seat 23 drives the multiple groups of second manipulators 25 to move up and down.

[0063] The cleaning device 3 is used to clean the battery 7; the drying device 4 is used to air-dry the cleaned battery 7, and the drying device 4 includes a cold air drying component 42 and / or a hot air drying component 41; the unloading device 5 is used to transport the cleaned battery 7.

[0064] Furthermore, the battery conveying mechanism 11 includes a first support frame 111, a conveyor belt 112 and a limit plate 113 arranged on the first support frame 111, the limit plates 113 are in two groups and are parallel to the conveying direction of the conveyor belt 112, the two groups of limit plates 113 are respectively located on both sides of the conveyor belt 112, and the battery 7 is placed on the conveyor belt 112 and between the two groups of limit plates 113. The setting of the limit plate 113 has a limiting effect on the battery 7 to prevent the battery 7 from falling.

[0065] Furthermore, the limiting plate 113 is provided with a plurality of rollers 114 at intervals along its length direction, and the battery 7 is placed on the conveyor belt 112 and located between the rollers 114 of the two sets of limiting plates 113. During the conveying process of the battery 7, the rollers 114 can rotate, which can reduce the friction between the battery 7 and the contact surface, and facilitate the conveying of the battery 7.

[0066] Furthermore, the distance between the rollers 114 of the two groups of limiting plates 113 is smaller than the distance between the two groups of limiting plates 113 , so that the arrangement of the rollers 114 can prevent the battery 7 from directly contacting the limiting plates 113 , thereby protecting the battery 7 .

[0067] Furthermore, the battery conveying mechanism 11 further comprises a battery temporary storage station 115 , which is located on the first support frame 111 , so as to facilitate temporarily placing the conveyed battery 7 in the battery temporary storage station 115 .

[0068] Furthermore, the first manipulator assembly 12 includes a first manipulator 121 for grasping the battery 7, a Z-axis linear module 122 for controlling the first manipulator 121 to move along the Z-axis direction, an X-axis linear module 123 for controlling the Z-axis linear module 122 to move along the X-axis direction, and a Y-axis linear module 124 for controlling the X-axis linear module 123 to move along the Y-axis direction.

[0069] In this embodiment, the Z-axis linear module 122, the X-axis linear module 123, and the Y-axis linear module 124 can all be linear modules of the prior art. The Y-axis linear module 124 is disposed on the second support frame 125. The X-axis linear module 123 is connected to the Y-axis slide of the Y-axis linear module 124. The motor of the Y-axis linear module 124 is operated to move the Y-axis slide, thereby driving the X-axis linear module 123 to move along the Y-axis direction. The Z-axis linear module 122 is connected to the X-axis slide of the X-axis linear module 123. The motor of the X-axis linear module 123 is operated to move the X-axis slide, thereby driving the Z-axis linear module 122 to move along the X-axis direction. The first manipulator 121 is connected to the Z-axis slide of the Z-axis linear module 122. The motor of the Z-axis linear module 122 is operated to move the Z-axis slide up and down, thereby driving the first manipulator 121 to move along the Z-axis direction.

[0070] Furthermore, the battery placement platform 13 includes a third support frame 131 and a support plate 132 arranged on the third support frame 131, a first battery placement plate 133, a second battery placement plate 134, and a reverse motion mechanism for controlling the reverse movement of the support plate 132 and the second battery placement plate 134. The first battery placement plate 133 is slidably arranged on the support plate 132, and the support plate 132 is also provided with a second lifting mechanism 135 for controlling the movement of the first battery placement plate 133 along the Z-axis direction. Specifically, a sliding bar 136 is arranged at the bottom of the first battery placement plate 133, and the sliding bar 136 is slidably connected to the support plate 132. The second lifting mechanism 135 can be a cylinder or a hydraulic cylinder. Under the action of the second lifting mechanism 135, the first battery placement plate 133 can be lifted and lowered on the support plate 132. The first manipulator assembly 12 is used to grab the battery 7 from the battery conveying mechanism 11 to the first battery placement plate 133 and the second battery placement plate 134 of the battery placement platform 13.

[0071] In this embodiment, when it is necessary to place the battery 7 on the first battery placement plate 133, the second lifting mechanism 135 controls the first battery placement plate 133 to rise to a position flush with the second battery placement plate 134. For batteries 7 of the same size, there is no need to adjust the height of the first manipulator 121 along the Z-axis direction (i.e., the vertical direction), so the battery 7 can be grasped and placed, saving operating steps.

[0072] In one embodiment, the reverse motion mechanism includes a synchronous belt 137 , and the support plate 132 and the second battery placement plate 134 are connected to the lower side portion 137 b and the upper side portion 137 a of the synchronous belt 137 , respectively.

[0073] Furthermore, the synchronous belt 137 is provided in two groups and is respectively provided on two side plates provided in parallel with the third support frame 131 , and both ends of the support plate 132 and the second battery placement plate 134 are respectively connected to the two groups of synchronous belts 137 .

[0074] Specifically, the reverse motion mechanism also includes a reverse motion motor 138 and two transmission shafts 139. Each group of synchronous belts 137 is connected by two pulleys arranged at intervals. The two pulleys arranged opposite to each other of the two groups of synchronous belts 137 are connected by a transmission shaft 139. The two ends of the transmission shaft 139 are respectively rotatably connected to the two side plates arranged parallel to the third support frame 131. The reverse motion motor 138 is arranged on a side plate of the third support frame 131, and the reverse motion motor 138 is transmission-connected to the end of a transmission shaft 139. The two ends of the support plate 132 are respectively connected to the lower side portions 137b of the two groups of synchronous belts 137, and the two ends of the second battery placement plate 134 are respectively connected to the upper side portions 137a of the two groups of synchronous belts 137. The reverse motion motor 138 runs, driving the transmission shaft 139 connected to it to rotate. The rotation of the transmission shaft 139 causes the two sets of synchronous belts 137 to rotate synchronously. Since the upper and lower sides of the synchronous belt 137 run in opposite directions, the support plate 132 and the second battery placement plate 134 run in opposite directions, making it easier for the first battery placement plate 133 and the second battery placement plate 134 to be alternately placed in the position where the first manipulator 121 places the battery 7.

[0075] In one embodiment, the battery conveying mechanism 11 can convey the battery 7 along the Y-axis direction, and convey the battery 7 to a position where the first manipulator 121 can grab the battery 7. Under the action of the Z-axis linear module 122, the X-axis linear module 123, and the Y-axis linear module 124, the first manipulator 121 can move in three directions, so that the battery 7 on the battery conveying mechanism 11 can be placed at different positions of the first battery placement plate 133 and the second battery placement plate 134, so that the battery 7 is arranged in multiple positions along the length direction of the first battery placement plate 133 and the second battery placement plate 134, so that the subsequent second manipulator 25 can directly clamp a whole row of batteries 7 when clamping the battery 7, that is, multiple second manipulators 25 on a lifting support seat 23 can clamp all the batteries 7 on the first battery placement plate 133 or the second battery placement plate 134 at one time, saving operation time. The number of batteries 7 clamped by the second manipulator 25 is not limited by the battery conveying mechanism 11, and the length of the first battery placement plate 133 or the second battery placement plate 134 can be designed as needed to place a suitable number of batteries 7. The first battery placement plate 133 and the second battery placement plate 134 can alternately place the batteries 7, so that the first manipulator 121 can continuously grab the batteries 7 and place them on the battery placement platform 13, saving time.

[0076] Furthermore, the first manipulator 121 and the second manipulator 25 each include two clamping arms 251 and a distance adjustment mechanism for adjusting the distance between the two clamping arms 251 .

[0077] An implementation method of the distance adjustment mechanism is as follows: Figure 8 As shown, the distance adjustment mechanism can be a first power rod 252, such as a hydraulic cylinder or a pneumatic cylinder. Specifically, the first manipulator 121 is arranged on the Z-axis slide of the Z-axis linear module 122 through the clamping arm support 126, and the first power rod 252 is arranged on the clamping arm support 126. At least one clamping arm 251 is connected to the piston rod of the first power rod 252. Under the action of the first power rod 252, the distance between the two clamping arms 251 can be adjusted. Preferably, the first power rod 252 has a double piston rod, and the running directions of the two piston rods are opposite. The two clamping arms 251 are respectively connected to the two piston rods of the first power rod 252. Under the action of the first power rod 252, the running directions of the two clamping arms 251 are opposite, so that the distance between the two clamping arms 251 can be adjusted.

[0078] Another embodiment of the distance adjustment mechanism is as follows: Figure 9-11As shown, a support beam 253 is provided at the top of the clamping arm 251 of the second manipulator 25, and the distance adjustment mechanism includes a second motor 256 and a second screw 254, the second motor 256 is provided on the lifting support seat 23, the second screw 254 is rotationally connected to the lifting support seat 23, the second motor 256 is transmission-connected to the second screw 254, the support beam 253 provided at the top of the clamping arm 251 of the second manipulator 25 is threadedly connected to the second screw 254, and the thread rotation directions are opposite, and the two ends of the support beam 253 are slidably connected to the lifting support seat 23. Or
