Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0031] In this embodiment, Figures 1 to 6 As shown, the machine comprises a platform 1 and a carrying mechanism 2 , a detecting mechanism 3 , a grabbing mechanism 4 and a sorting mechanism 5 which are arranged on the platform 1 .

[0032] The carrier mechanism 2 includes a carrier platform 21 for carrying a battery top cover sheet. In this embodiment, the battery top cover sheet is a battery top cover sheet 7. The carrier platform 21 is provided with two battery top cover sheet placement stations 25 along its own translational movement direction. Specifically, a detachable mounting block 251 is provided on the carrier platform 21. The two mounting blocks 251 are aligned along the front and rear direction of the carrier platform 21. The surface of each mounting block 251 is provided with a horizontal surface 252 for horizontally placing the battery top cover sheet 7. The horizontal surface 252 is provided with positioning protrusions 253 on the front and rear sides of the battery top cover sheet 7, that is, the battery top cover sheet 7 is located between the positioning protrusions 253 on both sides to prevent the battery top cover sheet 7 from shaking when the carrier platform 21 moves. In this embodiment, the battery top cover sheet 7 is a rectangular plate-shaped battery top cover sheet.

[0033] The carrying mechanism 2 also includes a first driving group that drives the bearing platform 21 to perform lifting and translational movements. The first driving group includes a first translation sliding device 22, a first base 23 and a first lifting device 24. The first translation sliding device 22 includes a slide rail located on the machine platform 1, and a slider is slidably matched on the slide rail. The slider is driven by a driving member to perform reciprocating translational movement along the slide rail. Since the slide rail is arranged along the front and rear directions of the bearing platform 21, the first base 23 is fixed on the slider, so that the first base 23 performs reciprocating translational sliding forward and backward with the slider. A first lifting device 24 is provided on the first base 23. The first lifting device 24 includes a driving member fixed on the slider, and the telescopic end of the driving member is vertically upwardly arranged. The bearing platform 21 is fixed on the telescopic end of the driving member, so that the bearing platform 21 can move up and down with the telescopic end of the driving member, thereby forming a lifting movement. Therefore, under the joint action of the first translation sliding device 22 and the first lifting device 24, the bearing platform 21 can simultaneously perform translational sliding in the front and rear directions and lifting and lowering movements in the height direction.

[0034] The detection mechanism 3 includes a visual detection component and a second drive group located in front of the upper part of the load-bearing platform 21.

A second base 34 is provided on the second translation sliding device 33. The second base 34 can perform horizontal reciprocating translation along the second translation sliding device 33. In this embodiment, the second translation sliding device 33 is in a position that is horizontally perpendicular to the first translation sliding device 22. Therefore, the second base 34 reciprocates in a direction that is horizontally and vertically relative to the translation direction of the load-bearing platform 21. In this embodiment, the battery top The length direction of the cover piece 7 is consistent with the direction of the second translation sliding device 33, that is, the detection mechanism 3 moves back and forth along the length direction of the battery top cover piece 7. The visual detection component includes a camera 31 and some accessories electrically connected to the camera 31. The visual detection component in this embodiment is mainly the camera 31. The camera 31 is installed on the second base 34, so the camera 31 moves back and forth along the second translation sliding device 33 with the second base 34. The camera 31 faces downward and is used to photograph whether the pole on the battery top cover piece 7 is in place, so as to determine whether the battery top cover piece 7 is qualified. The specific structure and working principle of the camera 31 in this embodiment are the same as conventional visual detection on the market, which will not be repeated here.

[0035] The gripping mechanism 4 includes a manipulator 41 that can perform lifting and rotating movements along the machine 1, a third driving group that drives the manipulator 41 to perform lifting and rotating movements, and a suction cup assembly 46 installed on the manipulator 41 and sucking the battery top cover sheet on the carrier 21. The third driving group includes a third base 42 fixed to the machine 1, and a first rotating driving device 43 is provided on the third base 42. The first rotating driving device 43 is usually a motor or a driving member that can rotate at the output end. The output end of the first rotating driving device 43 is provided with a rotating arm 44, so that the rotating arm 44 can rotate along the third base 42, a third translation sliding device 45 is provided on the rotating arm 44, the manipulator 41 is slidably connected to the third translation sliding device 45, the third translation sliding device 45 is the same as the first translation sliding device 22 in structure and movement principle, the manipulator 41 performs lifting motion relative to the rotating arm 44 through the third translation sliding device 45, and the suction cup assembly 46 is installed on the manipulator 41, so the suction cup assembly 46 can perform lifting and rotating motion relative to the support platform 21 under the joint action of the manipulator 41 and the third driving group.

[0036] The suction cup assembly 46 includes a fixing seat 461 fixed to the manipulator 41, and the fixing seat 461 is provided with two symmetrically distributed slide grooves 462, and each slide groove 462 is movably connected with a fixing block 463. In the present embodiment, the slide groove 462 is arranged along the length direction of the battery top cover sheet 7 and is located in the same straight line. The fixing block 463 includes a limit block and a fixing column integrated with the limit block, the fixing column is inserted into the slide groove 462, the limit block is located at the top of the slide groove 462, the limit block and the fixing column slide back and forth along the slide groove 462 together, a first through hole is provided on the limit block, and a second through hole is correspondingly provided on the fixing seat 461. When the positioning block slides to a preset position, a fastener passes through the first through hole and the second through hole to form a fixation, so that the two fixing blocks 463 can adjust the relative distance along the corresponding slide groove 462, and a suction cup is provided at the bottom of each fixing block 463, so that the battery top cover sheets 7 of different lengths can be sucked. In the present embodiment, the suction cup is a conventional suction cup structure on the market, so the specific structure and working principle are not repeated here.

[0037] The sorting mechanism 5 includes a first transport component 51 and a second transport component 52 respectively located on both sides of the gripping mechanism 4. The first transport component 51 and the second transport component 52 are both conveyor belts. In this embodiment, the first transport component 51 and the second transport component 52 are used to transport qualified battery top cover sheets 7 and unqualified battery top cover sheets 7 respectively. A flip mechanism 6 is also provided on one side of the first transport component 51. The flip mechanism 6 includes a fourth base 61 located on one side of the first transport component 51. A second rotary drive device 62 is provided on the fourth base 61. A flip plate 63 is provided at the output end of the second rotary drive device 62. The second rotary drive device 62 is usually a motor or a driving member that can rotate at the output end. A rotating shaft 66 is provided at the output end of the second rotary drive device 62. The flip plate 63 is horizontally welded or installed on the rotating shaft 66, that is, the length direction of the flip plate 63 is in the same direction as the axial direction of the rotating shaft 66, so that the flip plate 63 passes through the second rotary drive device 62. The turning drive device 62 realizes the flipping. In this embodiment, a battery top cover piece positioning groove 64 is provided on the flip plate 63. The bottom surface of the battery top cover piece positioning groove 64 is a horizontal plane. A protrusion 65 is provided around the horizontal plane to form the battery top cover piece positioning groove 64. The battery top cover piece positioning groove 64 is in the starting position with the front side facing upward. When the flip plate 63 flips 180 degrees toward the first transport component 51, the battery top cover piece 7 located in the battery top cover piece positioning groove 64 will be placed on the first transport component 51 in the reverse direction, so that the battery top cover piece 7 is in a state of facing upward with the reverse side, which is convenient for the subsequent production process. It should be noted that when the flip plate 63 is flipping, due to the blocking effect of the protrusion 65, the battery top cover piece 7 will move down and abut against the protrusion 65, so the battery top cover piece 7 will not fall off the flip plate 63.

[0038] In addition, the carrier mechanism 2 also includes positioning seats 27 located on the left and right sides of the carrying platform 21. In the present embodiment, there are four positioning seats 27, and two of the positioning seats 27 are respectively located on both sides of the carrying platform 21 to form a group of battery top cover piece positioning stations 26. The two groups of battery top cover piece positioning stations 26 are arranged one by one with the battery top cover piece placement stations 25 along the translational movement direction of the carrying platform 21, so that the carrying platform 21 can transfer the battery top cover pieces 7 on the two battery top cover piece placement stations 25 to the corresponding battery top cover piece positioning stations 26 at one time, so as to realize the positioning of the battery top cover piece 7, so as to facilitate the manipulator 41 to grab the battery top cover piece 7 on the battery top cover piece positioning station 26 closest to the manipulator 41. As the carrying platform 21 moves forward and backward and rises and falls, the battery top cover piece 7 on the front battery top cover piece positioning station 26 and the battery top cover piece placement station 25 are transferred backward in sequence to the last battery top cover piece positioning station 26.

[0039] Its working principle is that the battery top cover sheet 7 is transmitted to the bottom of the detection mechanism 3 after the previous process is completed, and is photographed by the camera 31 of the detection mechanism 3 to determine whether the current battery top cover sheet 7 is qualified, and the carrying platform 21 moves to the bottom of the battery top cover sheet 7, and the carrying platform 21 is located at the front battery top cover sheet placement station 25, that is, the first battery top cover sheet placement station 25 carries the battery top cover sheet 7 from bottom to top, and then the carrying platform 21 descends and moves backward, and transfers the battery top cover sheet 7 to the first battery top cover sheet positioning station 26, so that the battery top cover sheet 7 remains on the first battery top cover sheet positioning station 26, and then the carrying platform 21 moves forward again, and the first battery top cover sheet placement station 25 of the carrying platform 21 carries a new battery top cover sheet 7 again. In the process of carrying the new battery top cover sheet 7, the carrying platform 21 is located at the rear battery top cover sheet placement station 25, that is, the second battery top cover sheet placement station 25 will simultaneously move the battery top cover sheet 7 located at the first battery top cover sheet positioning station 26, and then the carrying platform 21 descends again and moves backward. The carrier 21 moves backward. At this time, the carrier 21 carries two battery top cover sheets 7 in front and behind. Then the carrier 21 moves backward and transfers the two battery top cover sheets 7 to the two battery top cover sheet placement stations 25 at the same time. Then the suction cup assembly 46 of the manipulator 41 absorbs the battery top cover sheet 7 on the second battery top cover sheet placement station 25. And so on, so that the carrier 21 transfers the battery top cover sheets 7 one by one to the battery top cover sheet placement station 25 by moving and lifting, waiting for the manipulator 41 to absorb, according to the detection mechanism 3 After determining whether it is qualified, the robot 41 transfers the qualified battery top cover sheet 7 to the top of the flip plate 63 and places it on the flip plate 63. After the battery top cover sheet 7 is flipped by the flip plate 63, it is placed on the first transport component 51 with the reverse side facing up, so as to facilitate transmission to the subsequent process for processing; the robot 41 transfers the unqualified battery top cover sheet 7 directly to the top of the second transport component 52 and places it on the second transport component 52, so that the unqualified battery top cover sheet 7 is transported through the second transport component 52, and finally achieves automatic sorting and unloading.

[0040] The driving member or driving device in this embodiment can be a hydraulic cylinder, a pneumatic cylinder or an electric motor, etc.

[0041] The present utility model is not limited to the above-mentioned optimal implementation mode.
