[0030] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0031] like Figure 1 The utility model is a structural schematic diagram of a suction cup gripper for a battery tray water cooling plate, comprising a frame 1 and two gripper units 2 that can move closer to or farther away from each other. The gripper units 2 are mounted on the frame 1 and are used to grip and transport the battery tray water cooling plate.

[0032] like Figure 1 , Figure 4 As shown, a displacement sensor 4 for detecting the position of the gripper assembly 21 is installed on the frame 1. The displacement sensor 4 is a Balluff displacement sensor. The presence of the displacement sensor 4 can make the positioning of the gripper unit 2 more accurate and avoid mechanical errors in movement.

[0033] like Figure 1 , Figure 4 As shown, the rack 1 includes a frame 11 and a connecting frame 12. The frame 11 is a square structure. The connecting frame 12 is located inside the frame 11, and the connecting frame 12 and the frame 11 are fixedly connected. The connecting frame 12 is used to connect with the quick-change disk, which can speed up the disassembly and installation between the rack 1 and the quick-change disk, thereby speeding up the replacement and maintenance efficiency. The gripper unit 2 is installed on the rack 1, and the frame 11 is surrounded by an octagonal tube.

[0034] like Figure 1 , Figure 2 As shown, the gripper unit 2 includes two gripper assemblies 21 arranged at intervals, and the gripper assembly 21 includes a suction piece 211, a mounting seat 212, a protective driving piece 213, a connecting plate 214 and a protective piece 215. The suction piece 211 is a vacuum sponge suction cup, and the suction piece 211 is used to suck the battery tray water cooling plate. The mounting seat 212 and the suction piece 211 are fixedly connected, one end of the connecting plate 214 is rotatably connected to the mounting seat 212, and the other end is rotatably connected to the middle part of the protective piece 215. The protective driving piece 213 is The output end is rotatably connected to the upper end of the protective member 215. The protective driving member 213 is used to provide power for the operation of the protective member 215. The protective driving member 213 can be a cylinder or a power element such as a hydraulic cylinder. This application does not make specific limitations on this. The mounting seat 212, the protective driving member 213, the connecting plate 214 and the protective member 215 constitute a mechanism that can drive the protective member 215 to rotate, so that the protective member 215 can rotate to the bottom of the adsorption member 211 to provide support for the water-cooling plate of the dropped battery tray.

[0035] After the adsorption member 211 absorbs the water-cooling plate of the battery tray, the lower end of the protection member 215 turns over to the bottom of the adsorption member 211 .

[0036] like Figure 2 As shown, the protective member 215 includes a connecting portion 2151 and a protective portion 2152. The upper end of the connecting portion 2151 is rotatably connected to the output end of the protective driving member 213, the middle portion of the connecting portion 2151 is rotatably connected to the connecting plate 214, the lower end of the connecting portion 2151 is fixedly connected to the protective portion 2152, and the protective portion 2152 is an L-shaped structure. The protective portion 2152 is used to hold the bottom of the battery tray water cooling plate. When the protective member 215 is located below the battery tray water cooling plate, the protective portion 2152 drags the battery tray water cooling plate.

[0037] The adsorption member 211 and the frame 1 are connected via a sliding assembly 22, and the sliding assembly 22 includes a guide rail 221 extending along the X-axis direction and a slider 222 matching the guide rail 221. The guide rail 221 and the frame 1 are fixedly connected, the guide rail 221 and the slider 222 are slidingly connected, and the slider 222 and the adsorption member 211 are fixedly connected. Through the design of the sliding assembly 22, the stability of the movement of the gripper unit 2 can be increased.

[0038] like Figure 1 , Figure 2 As shown, a laser rangefinder 3 for detecting whether the battery tray water cooling plate has fallen is installed on the adsorption member 211, which can provide warning information so that workers can react quickly and handle the fallen battery tray water cooling plate.

[0039] like Figure 3 , Figure 5 As shown, the gripper unit 2 also includes a connecting piece 23, and the gripper assemblies 21 are located at both ends of the connecting piece 23. The ends of the connecting piece 23 are fixedly connected to the gripper assemblies 21 on the side thereof, and the nut seat 63 is fixedly connected to the connecting piece 23 of the gripper unit 2 corresponding thereto. The connecting piece 23 is an octagonal tube, and the connecting piece 23 connects the two gripper assemblies 21 in the same gripper unit 2, thereby increasing the synchronization of the two gripper assemblies 21 and avoiding errors when they move.

[0040] The suction cup gripper also includes a visual positioning unit 5 for detecting the position of the battery tray water cooling plate. The visual positioning unit 5 is located in the frame 11 , and the visual positioning unit 5 is provided on both sides of the connecting frame 12 .

[0041] like Figure 1 , Figure 3 , Figure 5As shown, the suction cup gripper also includes an adjustment unit 6, which is used to provide power for the two gripper units 2 to move closer to or away from each other. The adjustment unit 6 includes an adjustment drive 61, an adjustment screw 62 and two nut seats 63. The output end of the adjustment drive 61 is transmission-connected with the adjustment screw 62. The adjustment drive 61 is used to provide power for the rotation of the adjustment screw 62. The adjustment screw 62 is a motor, and the present application does not make any specific limitation on this. The adjustment screw 62 has two threaded sections arranged at intervals, and the threaded directions of the threaded sections are opposite. The threaded sections and the nut seats 63 correspond one-to-one, and the threaded sections and the corresponding nut seats 63 are threadedly connected. The nut seats 63 and the gripper units 2 correspond one-to-one, and the nut seats 63 and the corresponding connecting piece 23 of the gripper unit 2 are fixedly connected.

[0042] Working principle: When the suction cup gripper is adapted to the battery tray water cooling plate, the distance between the two gripper units 2 is adjusted according to the size of the battery tray cooling plate to be grasped, the adjustment drive 61 is started to drive the adjustment screw 62 to rotate, and the two gripper units 2 are controlled to approach or move away from each other according to the rotation direction of the adjustment screw 62. During this process, the displacement sensor 4 detects the position of the gripper unit 2 in real time to make the moving position accurate.

[0043] The quick-change plate is connected to the lifting unit, which can be a hydraulic cylinder. During grabbing, the visual positioning unit 5 detects the position of the battery tray water-cooling plate and moves the suction cup gripper as a whole to above the battery tray water-cooling plate. The suction cup gripper drops as a whole until the adsorption component 211 contacts the battery tray water-cooling plate. The adsorption component 211 starts to absorb the battery tray water-cooling plate. The suction cup gripper rises as a whole, and then the protective drive component 213 starts to rotate the protective component 215 and move the protective part 2152 of the protective component 215 to below the adsorption component 211 to provide protection for the battery tray water-cooling plate. During the transfer process, the laser rangefinder 3 monitors the battery tray water-cooling plate in real time.

[0044] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
