Description

Technical Field

[0001] The present invention relates to the technical field of battery cover processing, and particularly relates to a processing and conveying line for a battery cover of a new energy electric vehicle. Background Art

[0002] The battery of a new energy electric vehicle adopts a packaging process, in which a batch of standard-sized battery cells are packaged together according to professional technology. The outermost package includes a battery cover, which is usually made of aluminum alloy or composite material and is formed by high-pressure die-casting or injection molding processes to ensure structural strength and reduce weight. The raw material for the production of the battery cover is usually in the form of a plate, and the plate needs to be transferred to the production line through a processing and conveying line. Existing processing and conveying lines can basically meet the daily use requirements, but there are still some deficiencies that need to be improved.

[0003] Patent document CN212607351U discloses a metal plate transfer mechanism on February 26, 2021, including: a spreader; a bracket suspended on the spreader; a plurality of suction cups arranged on the bracket and used for adsorbing the metal plate, the openings of the suction cups face downward, and the plurality of suction cups are arranged in an array in the horizontal plane; a negative pressure source connected to the suction cups; a hand push rod connected to the bracket and extending out of the edge of the bracket. The plurality of suction cups are arranged on the bracket and are arranged in an array in the horizontal plane. The suction cups can adsorb the metal plate by being connected to the negative pressure source. The spreader can drive the bracket to move in the vertical and horizontal directions, so as to realize the transfer of the metal plate, which can improve the transfer efficiency of the metal plate while saving production costs. At the same time, the operator can control the direction of the bracket by holding the hand push rod to prevent the metal plate from shaking or rotating during the process of transferring the metal plate, and can also facilitate the operator to adjust the direction of the metal plate when the metal plate is about to be transferred to the designated position.

[0004] In the prior art such as the above patent, the suction cups are arranged in an array and approach the adsorbed flat plate by lifting and moving. The suction cups are usually made of elastic material. After repeated use, they are prone to deformation, resulting in errors in the bottom surface height of each suction cup. Furthermore, when used again, some suction cups are prone to the problem of abnormal adsorption. Therefore, there is an urgent need for a processing and conveying line for a battery cover of a new energy electric vehicle to solve the above problems. Summary of the Invention

[0012] Preferably, a nozzle is arranged on the inner side of the suction cup at the lower end of the first lifting rod, a piston assembly for controlling the nozzle to spray liquid is arranged on the side wall of the first lifting rod, and the movement of the piston assembly is linked to the swing of the rod body.

[0013] Preferably, the piston assembly includes a cavity arranged on the side wall of the first lifting rod, a piston is movably arranged in the cavity, the piston is movably connected to the rod body at one end outside the cavity through a connecting rod, the inner end of the cavity is connected to a liquid inlet pipeline and a liquid outlet pipeline, one end of the liquid inlet pipeline extends out of the side wall of the first lifting rod, and one end of the liquid outlet pipeline is connected to a nozzle.

[0018] The new energy electric vehicle battery cover processing conveyor line is provided with a lever assembly.

Detailed implementation manners

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figure 1-7 , a processing conveyor line for a battery cover of a new - energy electric vehicle provided by the embodiment of the present invention includes a horizontal frame 1, a transport platform 2 is movably arranged on the horizontal frame 1, a suspension frame 3 is arranged under the transport platform 2 in a lifting - movable manner, and further includes: a first lifting rod 4, which is arranged on the suspension frame 3 in a lifting - movable manner, and a suction cup 5 is arranged at its lower end; a second lifting rod 6, which is arranged on the suspension frame 3 in an elastically - lifting - movable manner, and a cushion block 7 is arranged at its lower end; a lever assembly, which is arranged on the suspension frame 3 and is used to control the linkage of the first lifting rod 4 and the second lifting rod 6 to lift and lower in a one - up - one - down manner; an air extraction port 8, which is arranged on the side wall of the suction cup 5 and is used to connect to an air pump on the conveyor line.

[0033] Specifically, the horizontal frame 1 is set high above the processing production line of the battery cover. The horizontal frame 1 includes two horizontally parallel beams arranged at intervals. A slide rail is arranged on the upper end of the beam. The transport platform 2 is slidably connected to the slide rail. The movement of the transport platform 2 is controlled by a servo system. The suspension frame 3 includes a plurality of horizontally parallel cross bars. A plurality of suction cups 5 are arranged on each cross bar to obtain a plurality of adsorption points to meet the requirements of the adsorption force and balance of the battery cover. The first lifting rod 4 and the second lifting rod 6 are both arranged vertically; the first lifting rod 4 and the second lifting rod 6 are combined into a group of lifting rods, and at least two symmetrical groups of lifting rods are arranged on the same horizontal frame; the suction cup 5 can be elastically compressed and deformed, and is hollow inside; the second lifting rod 6 automatically maintains a downward movement trend under the action of the elastic force it is subjected to, that is, when the first lifting rod 4 and the second lifting rod 6 are not affected by external forces, the height of the first lifting rod 4 is higher than that of the second lifting rod 6; the pad 7 has a buffering effect; the lever assembly is combined with a group of lifting rods; the air suction port 8 is connected to the air pump through a conduit, and the conduit is a hose, which is limited on the suspension frame 3 to ensure the stability of the connection and is not affected by the activity of the first lifting rod 4. When the battery cover is released, the air pump 4 and the second lifting rod 6 are in a state of being lifted and lowered, and the suction cup 5 is lifted and lowered, so that the suction cup 5 can be lifted and lowered.

[0034] Compared with the prior art, a processing and conveying line for a new energy electric vehicle battery cover proposed in an embodiment of the present invention is provided with a lever assembly. Under the elastic action of the second lifting rod 6, the initial height of the cushion block 7 is lower than that of the suction cup 5. When the suspension bracket 3 descends to grasp the battery cover, the cushion block 7 contacts the battery cover first, and then through the lever action, the cushion block 7 rises relative to the suction cup 5, and the suction cup 5 fits onto the battery cover. Then, the air pump controls the air extraction port 8 to evacuate the internal space of the suction cup 5, thereby enabling the suction cup 5 to adsorb the battery cover, achieving the grasping. Moreover, the automatic balance of the first lifting rod 4 and the second lifting rod 6 realized by the lever assembly ensures that the suction cup 5 and the cushion block 7 simultaneously contact the upper surface of the battery cover, that is, ensures that each suction cup 5 can smoothly fit and adsorb the battery cover. Subsequently, during the process of releasing the battery cover, the air pump controls the suction cup 5 to cancel the adsorption, and the suspension bracket 3 slowly rises. Then, the second lifting rod 6 moves downward through the elastic restoring force, causing the cushion block 7 to move downward and the suction cup 5 to rise, thereby ensuring that the battery cover is forced to separate from the suction cup 5 in a timely manner, and preventing the problem that the battery cover deviates due to the non-synchronous separation of a certain side of the suction cup 5.

[0035] As a preferred technical solution of this embodiment, a lifting column 9 that is movably and penetratingly connected to the transport table 2 is fixedly provided at the upper end of the suspension bracket 3. A driving assembly for driving the lifting column 9 to move is provided on the transport table 2. Specifically, a sliding seat for guiding the lifting column 9 is provided on the transport table 2, and the lifting column 9 drives the suspension bracket 3 to move vertically. The driving assembly includes a servo motor installed on the transport table 2. The output end of the servo motor is coaxially connected to a driving gear. A rack meshing with the driving gear is vertically provided on the side wall of the lifting column 9. Thus, under the control of the servo motor to drive the driving gear to rotate, the driving gear drives the rack to control the lifting of the lifting column 9.

[0036] As a preferred technical solution of this embodiment, a support block 10 for connecting the first lifting rod 4 or the second lifting rod 6 is provided on the suspension bracket 3, and two support blocks 10 are in a group and are respectively connected to the first lifting rod 4 and the second lifting rod 6. The lever assembly is arranged between the two support blocks 10 in a group. Specifically, through holes are provided on the support block 10 for the first lifting rod 4 or the second lifting rod 6 connected thereto to movably pass through, defining the moving direction of the lifting rod.

[0037] As a preferred technical solution of this embodiment, a convex ring 11 is provided on the second lifting rod 6, and an elastic member 12 is connected between the upper side of the convex ring 11 and the support block 10. Specifically, the elastic member 12 can preferably be a spring, sleeved on the second lifting rod 6. The setting of the elastic member 12 keeps pushing the convex ring 11 away from the support block 10, that is, makes the second lifting rod 6 maintain a position lower than the first lifting rod 4 when not subject to external force, and the second lifting rod 6 has a tendency to return to the descending position after rising, thereby being used to help the battery cover separate from the suction cup 5 when the battery cover is released from the grasping.

[0038] As a preferred technical solution of this embodiment, the lever assembly includes a support plate 13 located between two support blocks 10 and fixedly arranged on the suspension bracket 3. A rod body 14 is rotatably arranged on the lower side of the support plate 13. The two ends of the rod body 14 are respectively movably connected to the first lifting rod 4 and the second lifting rod 6. Specifically, the support plate 13 is vertically arranged; the rod body 14 is rotatably connected to the support plate 13 at the middle position, the rotating shaft of the rod body 14 is horizontal, and the two ends swing up and down during rotation; waist-shaped holes are arranged at the ends of the rod body 14, and cylindrical rods are arranged on the first lifting rod 4 and the second lifting rod 6 and slidably connected in the waist-shaped holes, thereby realizing the synchronous lifting and lowering movement of the rod body 14 to drive the first lifting rod 4 and the second lifting rod 6 without interference.

[0039] The suction cup 5 has certain requirements for the smoothness of the adsorption surface. The surface roughness requirement of the battery cover is not high, and there is a problem that the suction cup 5 cannot be adsorbed during dry suction. The following embodiments are proposed to solve this problem.

[0040] In another embodiment proposed by the present invention, a nozzle 15 is arranged inside the suction cup 5 at the lower end of the first lifting rod 4, and a piston assembly for controlling the liquid spraying of the nozzle 15 is arranged on the side wall of the first lifting rod 4, and the movement of the piston assembly is linked with the swing of the rod body 14. Specifically, the nozzle 15 extends into the suction cup 5, and the height does not affect the compression adsorption of the suction cup 5. The liquid spraying direction arranged at the lower end of the suction cup 5 is conical and sprays downward directly below the suction cup 5; the piston assembly drives the rod body 14, so that every time the rod body 14 balances the lifting rods at both ends once, the piston assembly triggers a compression to make the nozzle 15 spray liquid, and when the rod body 14 automatically returns to the state of one high and one low at both ends, the piston assembly triggers an expansion to achieve quantitative liquid replenishment; the piston assembly is linked with the swing of the rod body 14, and the linkage is triggered only when the cushion block 7 abuts against the battery cover. At this time, the distance between the suction cup 5 and the nozzle 15 and the surface of the battery cover is close enough, and the liquid sprayed by the nozzle 15 can be smoothly sprayed on the surface of the battery cover and can accurately correspond to the area where the suction cup 5 fits, thereby improving the adsorption tightness of the suction cup 5 on the surface of the battery cover.

[0041] As a preferred technical solution of this embodiment, the piston assembly includes a cavity tube 16 provided on the side wall of the first lifting rod 4. A piston 17 is movably arranged in the cavity tube 16. One end of the piston 17 facing outside the cavity tube 16 is movably connected to the rod body 14 through a connecting rod 18. One end of the cavity tube 16 facing inwards is communicated with a liquid inlet pipeline 19 and a liquid outlet pipeline 20. One end of the liquid inlet pipeline 19 extends out of the side wall of the first lifting rod 4, and one end of the liquid outlet pipeline 20 is communicated with a nozzle 15. Specifically, the cavity tube 16 is hermetically connected to the piston 17, and the inside of the cavity tube 16 is used to store sealing liquid; a connecting member is provided at the outer end of the piston 17, the tail end of the connecting member is hinged to one end of the connecting rod 18, and the other end of the connecting rod 18 is hinged to the rod body 14. When the second lifting rod 6 rises, the rod body 14 drives the first lifting rod 4 to descend and approach the horizontal state. Thus, the rod body 14 pushes the piston 17 through the connecting rod 18. On the contrary, when the second lifting rod 6 descends, the connecting rod 18 pulls the piston 17; one-way valves with opposite directions are provided at the ends of the liquid inlet pipeline 19 and the liquid outlet pipeline 20 connected to the cavity tube 16, so that the cavity tube 16 only receives the liquid introduced by the liquid inlet pipeline 19 and only conducts the liquid into the liquid outlet pipeline 20; one end of the liquid inlet pipeline 19 extending to the outer wall of the first lifting rod 4 is used to connect to an external sealing liquid storage tank through a conduit.

[0042] In another embodiment proposed by the present invention, a control block 21 is coaxially connected to the rotating shaft of the rod body 14. A lifting groove 22 for only the lifting movement of the control block 21 is provided on the support plate 13. A limiting unit 23 for limiting the movement of the control block 21 is provided at the upper end of the lifting groove 22, and a rotating groove 24 for the control block 21 to rotate is provided at the lower end of the lifting groove 22. Specifically, a part is symmetrically cut off from two opposite sides in the radial direction of the cylindrical block to form the shape of the control block 21; the control block 21 is preferably made of a magnetically attracted material, and the limiting unit 23 is preferably an electromagnet, which is controlled by a servo system; the control block 21 only rotates in the rotating groove 24, that is, when the control block 21 corresponds to the rotating groove 24, the rod body 14 can swing. When the rod body 14 reaches the horizontal state at both ends of the balance, the control block 21 just corresponds to the lifting groove 22. At this time, the control block 21 can move upward. During the upward movement of the control block 21 in the lifting groove 22, the rod body 14 remains horizontal, that is, the elastic force rotation of the rod body 14 is restricted. And when the control block 21 rises to correspond to the limiting unit 23, the limiting unit 23 limits the control block 21 under the control of the servo system, thereby maintaining the height of the rod body 14 and keeping the rotation of the rod body 14 restricted; further, when the rod body 14 is locked in the above position, the suction cup 5 evacuates again.

[0043] As a preferred technical solution of this embodiment, the suction cup 5 is threadedly connected to the first lifting rod 4 through a screw sleeve 25. A rotating rod 26 is rotatably connected to the side wall of the first lifting rod 4. The lower end of the rotating rod 26 is rotatably and drivingly connected to the screw sleeve 25. A linkage assembly for controlling the rotation of the rotating rod 26 is provided on the support block 10. Specifically, the suction cup 5 is screwed to the first lifting rod 4 through the screw sleeve 25, and its height at the lower end of the first lifting rod 4 can be adjusted, and the suction cup 5 can be rotated by screwing. The nozzle 15 movably passes through the connection between the screw sleeve 25 and the suction cup 5 and is sealed. The axis of the rotating rod 26 is parallel to the axis of the first lifting rod 4. A snap ring is provided on the rotating rod 26, and a fork-shaped clamp for supporting and limiting the upper and lower sides of the snap ring is provided on the side wall of the first lifting rod 4 to support and limit the rotating rod 26 and satisfy the rotation of the rotating rod 26. The lower end of the rotating rod 26 is coaxially connected with a gear, and teeth meshing with the gear are provided on the outer circumference of the screw sleeve 25, and the axial length range of the teeth is greater than the axial range of the gear 1. The linkage assembly includes a through hole 27 provided on the support block 10. A spiral groove 28 is provided on the inner wall of the through hole 27, and a sliding protrusion 29 matching the spiral groove 28 is provided at the upper end of the rotating rod 26. A guide sleeve is provided at the lower end of the through hole 27, and the upper end of the rotating rod 26 is kept in the guide sleeve, thereby keeping the rotating rod 26 directly corresponding to the through hole 27. In the state where the second lifting rod 6 freely extends downward, the height of the first lifting rod 4 is such that the upper end of the rotating rod 26 carrying it is adjacent to the lower end of the through hole 27. That is to say, during the process of the lever assembly passively balancing the heights of the first lifting rod 4 and the second lifting rod 6, the rotating rod 26 does not enter the through hole 27 to act. Then, when the first lifting rod 4 and the second lifting rod 6 are balanced and both rise to a certain height together, the rotating rod 26 is triggered to enter the through hole 27 to generate a spiral drive.In actual use of this technical solution, the suspension bracket 3 drives the first lifting rod 4 and the second lifting rod 6 to descend above the battery cover. The cushion block 7 at the lower end of the second lifting rod 6 first abuts against the battery cover, and then through the lever assembly, the height balance of the first lifting rod 4 descending and the second lifting rod 6 ascending is automatically achieved until the cushion block 7 and the suction cup 5 simultaneously abut against the battery cover. During this process, the first lifting rod 4 drives the rotating rod 26 to descend relative to the support block 10, that is, the upper end of the rotating rod 26 does not pass through the through hole 27, and the suction cup 5 remains stationary. In addition, under the movement of the lever assembly, the nozzle 15 is linked to complete the liquid spraying on the area corresponding to the suction cup 5 on the battery cover; then, the suspension bracket 3 continues to descend, and the first lifting rod 4 and the second lifting rod 6 synchronously ascend relative to the suspension bracket 3. When the first lifting rod 4 ascends to a certain height, it drives the upper end of the rotating rod 26 to insert into the through hole 27, and makes the sliding protrusion 29 engage in spiral transmission with the spiral groove 28, causing the rotating rod 26 to rotate. The rotating rod 26 thus drives the screw sleeve 25 to rotate. The screw sleeve 25 engages in spiral transmission with the first lifting rod 4, causing the suction cup 5 to rotate spirally and descend a certain height relative to the first lifting rod 4. This spiral rotation of the suction cup 5 can, on the one hand, slide along the wet surface of the battery cover to further ensure sealing, and on the other hand, the suction cup 5 is elastically compressed to prepare for subsequent vacuum pumping; finally, after the lever assembly cannot rise anymore, height locking is performed, and then the suction cup 5 is evacuated and maintained through the air pump and the air extraction port 8, thereby completing the adsorption of the suction cup 5 to the battery cover under the condition of a fully wet and sealed contact surface. In addition, when canceling the adsorption of the battery cover, the suction cup 5 first stops evacuating, and then the suspension bracket 3 ascends relative to the battery cover. Then, under the elastic restoring force of the second lifting rod 6, the lever assembly, the first lifting rod 4, and the second lifting rod 6 first descend as a whole, causing the suction cup 5 to also rotate spirally to restore its position. Then, the lever assembly restores the first lifting rod 4 and the second lifting rod 6 to a state of one high and one low to ensure the separation of the suction cup 5 from the battery cover.

[0044] The above has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
