Description

Technical Field

[0001] The invention relates to the technical field of lithium battery processing, and in particular to a power lithium battery shell processing device. Background Art

[0002] When processing the power lithium battery shell, hydraulic equipment is usually used to stamp the metal sheet into shape in one go. During use, this method can keep the specifications of the produced power lithium battery shell consistent and has high practicality.

[0003] However, when the existing power lithium battery shell is stamped, due to the different materials of the metal sheets and the thin thickness of some metal sheets, the metal sheets are easily deformed too much when they are stamped into a specified shape at one time, and sometimes they are torn at the stamping bends, becoming defective products, which not only wastes raw materials, but also requires the machine to be stopped for removal, reducing the processing efficiency of the power lithium battery shell;

[0004] At the same time, when stamping the metal sheet, the contact between the metal sheet and the stamping part of the punching machine is very firm, resulting in greater friction. The edge of the power lithium battery shell is easily rubbed against the cover plate, causing scratches on the edge of the power lithium battery shell, resulting in the production of defective products and affecting subsequent processing.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original foundation. Summary of the invention

[0018] In the above scheme, by setting up a protection component, when the metal plate is processed for the first time, it is convenient to quickly adjust the curvature of the compressed steel plate according to the compression resistance of different batches of metal sheets, and reduce the degree of one-time deformation of the metal sheet during stamping, so that the metal sheet is first stamped into a shape with the same curvature as the compressed steel plate, thereby reducing the probability of damage to the metal sheet caused by one-time stamping. Through the initial buffering of the protection component and then the secondary processing of the mold, the metal sheet is stamped into a specified shape, so that the metal plate will not be torn due to excessive stress during processing. When the metal sheet is processed on the mold, since the metal sheet already has a certain deformation basis, it can be easier to form the metal sheet during processing, and the quality of the formed metal sheet is guaranteed, thereby improving the yield rate of the power lithium battery housing after forming.

[0019] By setting up a transfer component, the device can continuously and uninterruptedly process the metal sheets of the same batch when processing the metal sheets, thereby increasing the efficiency of the processing of the power lithium battery shells. At the same time, through the oil delivery component, during the process of the transfer component transferring the metal sheets, the first oil storage rod and the second oil storage rod can oil the surface of the metal sheet. The oil film formed by the lubricating oil forms a protective layer on the surface of the metal sheet. When the cover plate is squeezed on the metal sheet, the friction between the cover plate and the edge of the metal sheet can be reduced to avoid scratches on the surface of the metal sheet caused by excessive friction. At the same time, when the first oil storage rod and the second oil storage rod slide on the surface of the metal sheet, the dust on the surface of the metal sheet can be swept away to avoid the presence of debris on the surface of the metal sheet, which causes pits on the surface of the metal sheet after processing and affects normal use.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 11The present invention provides a technical solution: a power lithium battery shell processing device, comprising a control box 1, a first mounting plate 11 is arranged on the top of the control box 1, two groups of second mounting plates 12 are fixedly connected to the top of the first mounting plate 11, each group of second mounting plates 12 is fixedly connected to a third mounting plate 2, a first motor 21 is fixedly connected to the top of the third mounting plate 2, a hydraulic rod 22 is fixedly connected to one side of the third mounting plate 2, the hydraulic rod 22 is threadedly connected to the threaded shaft at the output end of the first motor 21, and a cover plate 3 is fixedly connected to the bottom of the hydraulic rod 22, and the two covers are fixedly connected to the first motor 21. A placement plate 4 is provided directly below the plate 3, a protection component 8 is provided on the placement plate 4 on one side, a mold 41 is fixedly connected to the placement plate 4 on the other side, an electric slide rail 5 is fixedly connected to the second mounting plates 12 on both sides, two groups of transfer components 6 are slidably connected to the electric slide rail 5 on one side, and a group of transfer components 6 is provided on the electric slide rail 5 on the other side. The two groups of transfer components 6 on the electric slide rail 5 are provided with oil brushing components 7. When the device is used on the assembly line, the transfer component 6 will suck up the metal sheet on the left side of the device and transfer it to the metal sheet on the placement plate 4. The cover plate 3 on the protective component 8 is pressed onto the protective component 8 by the action of the first motor 21 and the hydraulic rod 22, so that the metal sheet is processed for the first time. After the metal sheet is processed for the first time, the cover plate 3 rises, and the transfer component 6 transfers the metal sheet on the protective component 8 to the mold 41 on another placement plate 4. At the same time, the transfer component 6 also transfers the new metal sheet on the left side of the device to the protective component 8. Then, the two cover plates 3 descend at the same time, and the cover plate 3 on the protective component 8 presses the new metal sheet on the protective component 8. The metal sheet undergoes the first processing, and the metal sheet on the mold 41 will be processed and shaped by the cover plate 3. Then the two cover plates 3 rise at the same time. At this time, the transfer component 6 will transfer the metal sheet on the mold 41 to the assembly line on the right side of the device. At the same time, the metal sheet on the protection component 8 will be transferred to the mold 41, and the metal sheet on the left side of the device will be transferred to the protection component 8. By continuously transferring new metal sheets to the device for processing through the transfer component 6, and transferring the processed metal sheets to the assembly line at the same time, batch processing of metal sheets can be realized.

[0034] like Figures 1 to 8The bottom of the placement plate 4 is fixedly connected with a support seat 42, and the top of the placement plate 4 on one side of the protection component 8 is fixedly connected with a support frame 43, each side of the support frame 43 is provided with a sliding hole 432 of the same distance, and the bottom of the support frame 43 is provided with a sliding groove 434, and the bottom of the support frame 43 is fixedly connected with a threaded sleeve 433, and the bottom of the outer side of the support frame 43 is provided with an arc groove 431. The protection component 8 includes a second motor 81, and the second motor 81 is connected to the first gear shaft 82 through a belt 811. One side of the first gear shaft 82 is meshed with the second gear shaft 83, and push plates 84 are provided at both ends of the first gear shaft 82. One side of the push plate 84 is rotatably connected with a pressure steel plate 85, and the two ends of the first gear shaft 82 are fixedly connected with a hexagonal prism 821, and a threaded rod 822 is sleeved on the hexagonal prism 821. The threaded rod 822 is rotatably connected to one side of the push plate 84, and the push plate A group of evenly spaced push rods 841 are fixedly connected to the other side of 84, and the push rods 841 are rotatably connected to the connecting rod 852 on one side of the pressure steel plate 85. The inner side of the pressure steel plate 85 is fixedly connected to a supporting rib 851. Four push plates 84 are provided, and the push plates 84 are located on the inner side of the side of the support frame 43. One side of a group of two push plates 84 arranged opposite to each other is rotatably connected to a threaded rod 822, and one side of another group of two push plates 84 arranged opposite to each other is fixedly connected to a toothed plate 842. The two toothed plates 842 are respectively meshed and connected to the bottom of the first gear shaft 82 and the second gear shaft 83. The toothed plate 842 is slidably connected in the sliding groove 434 of the placement plate 4, the threaded rod 822 is inserted and threadedly connected in the threaded sleeve 433, the push rod 841 is inserted in the sliding hole 432, and the top two ends of the pressure steel plate 85 are rotatably connected to the support frame 43, and the bottom of the pressure steel plate 85 is located in the arc groove 431.

[0035] Before the first processing of the metal sheet, it is necessary to adjust the curvature of the pressure steel plate 85 according to the material of the metal sheet and the specifications of the power lithium battery housing. The rotation of the second motor 81 can drive the rotation of the first gear shaft 82 through the belt 811. When the first gear shaft 82 rotates, on the one hand, the rotation of the first gear shaft 82 will drive the rotation of the threaded rod 822 through the hexagonal prism 821. When the threaded rod 822 rotates, since the threaded rod 822 is threadedly connected in the threaded sleeve 433, the threaded rod 822 will move in the threaded sleeve 433. When the threaded rod 822 moves, The push plates 84 on both sides will be pushed to move the push plates 84. When the push plates 84 on both sides move, the push rods 841 will be used to push the pressure steel plates 85 to rotate on the support frame 43. On the other hand, when the first gear shaft 82 rotates, the second gear shaft 83 meshing with the first gear shaft 82 will be driven to rotate. At this time, the rotation of the first gear shaft 82 and the second gear shaft 83 will drive the toothed plate 842 at the bottom to move. When the toothed plate 842 moves, it will push the movement of the other two push plates 84. The movement of the other two push plates 84 will cause the remaining two pressure steel plates 85 to rotate on the support frame 43 through the push rods 841. 3, when the four pressure steel plates 85 rotate to one side of the arc groove 431, the pressure steel plate 85 stops rotating because the bottom of the pressure steel plate 85 is blocked, but the push rod 841 still applies force on one side of the pressure steel plate 85, and a certain curvature appears on one side of the pressure steel plate 85. When the curvature on the pressure steel plate 85 reaches the requirement, the second motor 81 stops rotating. At this time, when the cover plate 3 presses the metal sheet on the support frame 43, the metal sheet will be squeezed and deformed, but at this time, since the side of the support frame 43 is a pressure steel plate 85 with a certain curvature, the support ribs of the pressure steel plate 85 851, can improve the compressive resistance of the compressed steel plate 85, and at the same time, the elastic force of the steel plate itself allows itself to have a certain deformation. The push rod 841 will also support the compressed steel plate 85, and the metal sheet will not deform much, remain intact, and will not be torn. When the transfer component 6 transfers the metal sheet after the first processing to the mold 41, the cover plate 3 will punch the metal sheet for the second time. At this time, since the metal sheet already has a certain deformation basis, it can make the metal sheet easier to shape during processing, and the formed metal sheet can be made more complete, thereby ensuring the quality of the formed metal sheet.

[0036] like Figures 9 to 11The transfer assembly 6 includes a transfer rod 61, one end of the transfer rod 61 is arranged in the electric slide rail 5, and the other end of the transfer rod 61 is provided with a cylinder 62. The bottom of the piston rod in the cylinder 62 is fixedly connected to a support rod 63, and one end of the support rod 63 is provided with a suction cup 64. The oil brushing assembly 7 includes a mounting seat 71, the top of the mounting seat 71 is fixedly connected to the support rod 63, and both sides of the bottom of the mounting seat 71 are rotatably connected to a fixed rod 72, and the bottom of the fixed rod 72 is fixedly connected to a first oil storage rod 73, and both ends of the first oil storage rod 73 are rotatably connected to a second oil storage rod 74, and one end of the second oil storage rod 74 on the two first oil storage rods 73 abuts against each other, and auxiliary grooves 722 are provided on the opposite sides of the two fixed rods 72, and an auxiliary rod 721 is provided between the two fixed rods 72, and both ends of the auxiliary rod 721 are slidably connected to the auxiliary groove 722, and the two ends of the auxiliary rod 721 are connected to the bottom of the auxiliary groove 722. The cam 732 is provided with a first spring 723, and the outer side of the first oil storage rod 73 is provided with a wool sleeve 731. The bottom of the first oil storage rod 73 is fixedly connected to a fixing frame 732, and a trigger frame 733 is slidably connected to the fixing frame 732. A second spring 735 is provided between the trigger frame 733 and the top of the first oil storage rod 73. Sealing rods 734 are fixedly connected to both sides of the trigger frame 733. The bottom of the sealing rod 734 is inserted into the oil outlet hole at the bottom of the first oil storage rod 73. When the metal sheet is transferred to the protection component 8, the transfer rod 61 will move in the electric slide rail 5 so that the suction cup 64 is located directly above the metal sheet on the assembly line. Then the cylinder 62 is started to make the suction cup 64 descend. During the descent of the suction cup 64, the first oil storage rod 73 and the second oil storage rod 74 will contact the top of the metal sheet. As the support rod 63 descends, the bottoms of the first oil storage rod 73 and the second oil storage rod 74 will be squeezed on the metal sheet.

[0037] When the two fixing rods 72 open, the two first oil storage rods 73 move away from each other, and the auxiliary rod 721 located between the two fixing rods 72 slides upward in the auxiliary groove 722, and the first oil storage rods 73 and the second oil storage rods 74 on both sides slide in the opposite direction on the surface of the metal sheet. At this time, since the trigger frame 733 is squeezed by the metal sheet into the first oil storage rod 73 and the second oil storage rod 74, the sealing rod 734 leaves the oil outlet hole, and the oil in the first oil storage rod 73 and the second oil storage rod 74 flows through the oil outlet hole to the wool sleeve 731 and is smeared on the surface of the metal sheet through the wool sleeve 731. When the suction cup 64 transfers the metal sheet to the protective component 8, the suction cup 64 separates from the metal sheet and gradually rises. When the suction cup 64 rises, the first spring 723 located at the bottom of the auxiliary rod 721 contracts to move the auxiliary rod 721 downward. When the auxiliary rod 721 moves, the two fixing rods 72 rotate in the opposite direction and gradually close. When the second oil storage rod 73 and the second oil storage rod 74 are close to each other, the surface of the metal sheet will be oiled again so that the oil is evenly coated on the surface of the metal sheet. When the first oil storage rod 73 and the second oil storage rod 74 leave the surface of the metal sheet, the trigger frame 733 will return to its original position under the action of the second spring 735. At this time, the sealing rod 734 is re-inserted into the oil outlet hole, so that the oil in the first oil storage rod 73 and the second oil storage rod 74 stops flowing out. After the surface of the metal sheet is oiled, the oil film formed by the lubricating oil forms a protective layer on the surface of the metal sheet, so that when the cover plate 3 is squeezed on the metal sheet, the friction between the cover plate 3 and the edge of the metal sheet can be reduced, thereby avoiding scratches on the surface of the metal sheet due to excessive friction. At the same time, when the first oil storage rod 73 and the second oil storage rod 74 slide on the surface of the metal sheet, the dust on the surface of the metal sheet can be swept away, thereby avoiding the presence of debris on the surface of the metal sheet, causing holes to appear on the surface of the metal sheet after processing, affecting normal use.

[0038] An embodiment of the present invention provides a processing method for a power lithium battery housing processing device, comprising the following steps:

[0039] S1, the transfer component 6 moves the metal sheet on the assembly line to the protection component 8 of the placement plate 4. During this process, the oil brushing component 7 brushes oil on the top of the metal sheet, and the first hydraulic rod 22 presses the metal sheet through the cover plate 3. The staff adjusts the curvature of the pressure steel plate 85 according to the specifications of the power lithium battery shell, so that the metal sheet is pressed on the protection component 8 for the first time, so that the pressed part forms a surface with a certain curvature;

[0040] S2, the transfer component 6 transfers the first processed metal sheet to the mold 41 of the second placement plate 4. During the transfer process, the top of the metal sheet is brushed with oil again by the oil brushing component 7. At the same time, the transfer component 6 places a new metal sheet on the protection component 8 of the first placement plate 4, and brushes the top of the new metal sheet with oil;

[0041] S3, the two hydraulic rods 22 descend simultaneously, one hydraulic rod 22 performs the first processing on the metal sheet on the protection component 8 to form a surface with a certain curvature, and the other hydraulic rod 22 performs the second punching on the metal sheet on the mold 41, and finally the metal sheet on the mold 41 is formed, forming a continuous operation;

[0042] S4, the transfer component 6 is started again, and the metal sheets on the assembly line are transferred to the protection component 8, the metal sheets on the protection component 8 are transferred to the mold 41, and the metal sheets on the mold 41 are transferred to the subsequent assembly line.

[0043] The working principle of the technical solution provided by the present invention is as follows: when the device is used on the production line of power lithium batteries, the transfer component 6 will suck up the metal sheet located on the left side of the device and transfer it to the protection component 8 located on the placement plate 4, and then the cover plate 3 on the protection component 8 will press the metal sheet on the protection component 8 under the action of the first motor 21 and the hydraulic rod 22, so that the metal sheet undergoes the first processing. After the metal sheet has undergone the first processing, the cover plate 3 rises, and at this time the transfer component 6 will transfer the metal sheet located on the protection component 8 to the mold 41 located on another placement plate 4. At the same time, the transfer component 6 will also transfer the new metal sheet located on the left side of the device to the protection component 8. On the component 8, then, the two cover plates 3 will descend at the same time, the cover plate 3 located on the protection component 8 will perform the first processing on the new metal sheet, the metal sheet located on the mold 41 will be processed and formed by the cover plate 3, and then the two cover plates 3 will rise at the same time, at this time the transfer component 6 will transfer the metal sheet on the mold 41 to the assembly line on the right side of the device, at the same time, the metal sheet on the protection component 8 will be transferred to the mold 41, and the metal sheet on the left side of the device will be transferred to the protection component 8. By continuously transferring new metal sheets to the device for processing through the transfer component 6, and at the same time transferring the processed metal sheets to the assembly line, batch processing of metal sheets can be realized.

[0044] Before the first processing of the same batch of metal sheets, the staff needs to adjust the curvature of the compressed steel plate 85 according to the material and thickness of the metal sheets, that is, the specifications of the power lithium battery shell, and the different deformation resistance of different metal sheets. Through the rotation of the second motor 81, the first gear shaft 82 can be driven to rotate through the belt 811. When the first gear shaft 82 rotates, on the one hand, the rotation of the first gear shaft 82 will drive the rotation of the threaded rod 822 through the hexagonal prism 821. When the threaded rod 822 rotates, since the threaded rod 822 is threadedly connected in the threaded sleeve 433, the threaded rod 822 will move in the threaded sleeve 433. When the threaded rod 822 moves, it will push the push plates 84 on both sides to move the push plates 84. When the push plates 84 on both sides move, they will push the compressed steel plate 85 on the support through the push rods 841. The frame 43 rotates. On the other hand, when the first gear shaft 82 rotates, it will drive the second gear shaft 83 meshing with the first gear shaft 82 to rotate. At this time, the rotation of the first gear shaft 82 and the second gear shaft 83 will drive the bottom tooth plate 842 to move. When the tooth plate 842 moves, it will push the movement of the other two push plates 84. The movement of the other two push plates 84 will cause the remaining two pressure steel plates 85 to rotate on the support frame 43 through the push rod 841. When the four pressure steel plates 85 rotate to one side of the arc groove 431, the bottom of the pressure steel plate 85 is blocked, and the pressure steel plate 85 stops rotating at this time. However, since the push rod 841 still applies force on one side of the pressure steel plate 85, a certain curvature will appear on one side of the pressure steel plate 85. When the curvature on the pressure steel plate 85 reaches the requirement, the second motor 81 stops rotating.

[0045] At this time, when the cover plate 3 presses the metal sheet onto the support frame 43, the metal sheet will be squeezed and deformed. However, since the side of the support frame 43 is a compressed steel plate 85 with a certain curvature (the support ribs 851 of the compressed steel plate 85 can improve the compression resistance of the compressed steel plate 85, and the elastic force of the steel plate itself allows itself to have a certain deformation, and the push rod 841 will also support the compressed steel plate 85), the first deformation of the stamped metal sheet is not large at this time, and it remains intact without being torn.

[0046] When the transfer component 6 transfers the metal sheet after the first processing to the mold 41, the cover plate 3 will punch the metal sheet for the second time. At this time, since the metal sheet already has a certain deformation basis, it can be easier to form the metal sheet during processing, and the formed metal sheet can be more complete, thereby increasing the efficiency of the power lithium battery shell forming. When the metal sheet is transferred to the protection component 8, the transfer rod 61 will move in the electric slide rail 5 so that the suction cup 64 is located directly above the metal sheet on the assembly line. Then the cylinder 62 is started to lower the suction cup 64. During the descent of the suction cup 64, the first oil storage rod 73 and the second oil storage rod 74 will contact the top of the metal sheet. As the support rod 63 descends, the bottoms of the first oil storage rod 73 and the second oil storage rod 74 will be squeezed on the metal sheet. At this time, the two fixed rods 72 will open, so that the two first oil storage rods 73 are away from each other, and the auxiliary rod 721 located between the two fixed rods 72 will be in the auxiliary groove 722. When the first and second oil storage rods 73 and 74 are in contact with each other, the oil in the first and second oil storage rods 73 and 74 will flow to the wool sleeve 731 through the oil outlet hole, and be smeared on the surface of the metal sheet through the wool sleeve 731. When the suction cup 64 transfers the metal sheet to the protective component 8, the suction cup 64 separates from the metal sheet and gradually rises. When the suction cup 64 rises, the first spring 723 at the bottom of the auxiliary rod 721 will contract, causing the auxiliary rod 721 to move downward. When the auxiliary rod 721 moves, the two fixed rods 72 will rotate in the opposite direction and gradually close. The first and second oil storage rods 73 and 74 on both sides will gradually approach each other. When approaching each other, the surface of the metal sheet will be brushed with oil again, so that the oil is evenly smeared on the surface of the metal sheet.

[0047] When the first oil storage rod 73 and the second oil storage rod 74 leave the surface of the metal sheet, the trigger frame 733 will return to its original position under the action of the second spring 735. At this time, the sealing rod 734 is reinserted into the oil outlet hole to stop the oil in the first oil storage rod 73 and the second oil storage rod 74 from flowing out. After the surface of the metal sheet is oiled, an oil film formed by the lubricating oil forms a protective layer on the surface of the metal sheet, so that when the cover plate 3 is squeezed on the metal sheet, the friction between the cover plate 3 and the edge of the metal sheet can be reduced to avoid scratches on the surface of the metal sheet. At the same time, when the first oil storage rod 73 and the second oil storage rod 74 slide on the surface of the metal sheet, the dust on the surface of the metal sheet can be cleaned to avoid the presence of debris on the surface of the metal sheet, which will cause holes on the surface of the metal sheet after processing and affect normal use.
