Description

Technical Field

[0001] The present application relates to the field of battery cover plate processing devices, and in particular to a sealing rubber ring assembling device for a battery cover plate. Background Art

[0002] Currently, batteries are widely used in human life; in the actual preparation process of batteries, in order to make them have good airtightness, a sealing rubber ring is correspondingly arranged before the pole column welding of the battery cover plate, so that good airtightness is formed between the welded battery cover plate and the pole column.

[0003] In the related art, a pole column hole for installing the pole column is provided at the corresponding position of the pole column of the battery cover plate. The sealing rubber ring assembling device for the battery cover plate includes an operating table, a sealing rubber ring adapted to the pole column hole of the battery cover plate, an alignment station, and a manipulator. Among them, the alignment station and the manipulator are arranged on the operating table. The alignment station is used to carry the battery cover plate, and the manipulator can coincide with the alignment station in the top-down direction; first, the battery cover plate is placed on the alignment station, then the manipulator grabs the sealing rubber ring, and finally the sealing rubber ring is placed at the pole column hole of the battery cover plate to complete the process of sleeving the sealing rubber ring on the battery cover plate.

[0004] In view of the above related art, when the manipulator picks and places materials with its fingers, it may squeeze the side of the sealing rubber ring, causing the sealing rubber ring to undergo micro-deformation, so that a gap is generated between the sealing rubber ring and the outer shape of the pole column hole of the battery cover plate, reducing the alignment accuracy between the sealing rubber ring and the outer shape of the pole column hole of the battery cover plate, resulting in a decrease in the airtightness at the battery pole column. Summary of the Invention

[0005] In order to improve the alignment accuracy between the sealing rubber ring and the outer shape of the pole column hole of the battery cover plate and improve the airtightness at the battery pole column, the present application provides a sealing rubber ring assembling device and method for a battery cover plate.

[0006] In a first aspect, the present application provides a sealing rubber ring assembling device for a battery cover plate, adopting the following technical solution:

[0007] A sealing rubber ring assembly device for a battery cover plate, comprising an operating table, wherein the operating table is provided with an alignment station; further comprising a conveying device, a feeding device, an adsorption feeding device and a total driving device arranged on the operating table; the feeding device is provided with a material taking place, and the feeding device is used to convey the sealing rubber ring to the material taking place; the conveying device is used to drive the battery cover plate to overlap or misalign with the alignment station; the adsorption feeding device can move relative to the operating table, and the total driving device is used to drive the adsorption feeding device to move between the material taking place and the alignment station; the adsorption feeding device comprises an adsorption contact piece, an ejection limiting structure and a second driving device, the adsorption contact piece is provided with an adsorption end face for adsorbing the sealing rubber ring, the ejection limiting structure can slide vertically relative to the adsorption contact piece, and the second driving device is used to drive the ejection limiting structure to move vertically, the ejection limiting structure is adapted to the inner ring of the sealing rubber ring in shape, and the ejection limiting structure can extend or retract along the adsorption end face.

[0008] By adopting the above technical scheme, the adsorption and feeding device grabs the sealing rubber ring by adsorbing the upper end face of the sealing rubber ring, and will not squeeze the side face of the sealing rubber ring, thereby preventing the sealing rubber ring from being deformed during grabbing; the ejection limiting structure extends out from the adsorption end face of the adsorption and feeding device at the front edge of the adsorption of the sealing rubber ring, and when the adsorption and feeding device adsorbs the sealing rubber ring, the sealing rubber ring is inserted into the sealing rubber ring to limit the sealing rubber ring; after the adsorption and feeding device places the sealing rubber ring at the battery cover plate pole hole, the adsorption end face stops adsorption, and the ejection limiting structure retracts into the adsorption end face of the adsorption and feeding device. Through the above process, the sealing rubber ring can be positioned more accurately, and the sealing rubber ring will not be affected by the tangential force during the placement process, thereby preventing the sealing rubber ring from being deformed or shifted in position during placement; in summary, the above scheme can improve the alignment accuracy of the sealing rubber ring and the shape of the battery cover plate pole hole, thereby improving the airtightness at the battery pole.

[0009] Preferably, it also includes a plate-type supporting member and a lifting device for carrying the battery cover, wherein the plate-type supporting member is vertically slidably connected to the conveying device, and a clearance hole is provided on the conveying device, and the lifting device can lift the plate-type supporting member on the alignment station through the clearance hole.

[0010] By adopting the above technical solution, when the adsorption loading device lowers the sealing rubber ring, it will contact with the plate-type supporting member, generate pressure on the operating table, and may generate torque on the operating table, causing the operating table to drive the alignment station to tilt slightly, resulting in reduced alignment accuracy between the sealing rubber ring and the shape of the battery cover plate pole hole; when the adsorption loading device lowers the sealing rubber ring, the lifting device lifts and supports the plate-type supporting member, which can avoid slight tilt of the alignment station, improve the alignment accuracy between the sealing rubber ring and the shape of the battery cover plate pole hole, and improve the airtightness at the battery pole.

[0011] Preferably, the number of the relief holes is two, which are respectively arranged at positions corresponding to two pole holes of the battery cover plate on the alignment station.

[0012] By adopting the above technical solution, after the plate-shaped supporting member is jacked up, during the process of placing the sealing rubber ring, the pressure and the supporting force are at the same place, and the plate-shaped supporting member is more stable.

[0013] Preferably, a height-limiting bolt is arranged between the plate-shaped supporting member and the operating table, and the height-limiting bolt is threadedly connected to the operating table; a through hole with a diameter smaller than the outer diameter of the nut of the height-limiting bolt is arranged on the plate-shaped supporting member, and the plate-shaped supporting member is sleeved on the height-limiting bolt through the through hole.

[0014] By adopting the above technical solution, the jacking device jacks up the plate-shaped supporting member, and after the plate-shaped supporting member contacts the nut of the height-limiting bolt, it reaches the working height, and then the adsorption feeding device moves down to place the sealing rubber ring; through the above structure, the working height of the plate-shaped supporting member can be made consistent each time it is jacked up, and it can be avoided that the sealing rubber ring is extruded and deformed due to the different heights of the plate-shaped supporting member after the adsorption feeding device descends; the alignment accuracy of the sealing rubber ring and the outer shape of the pole hole of the battery cover plate is improved, and the airtightness at the battery pole is improved.

[0015] Preferably, a guiding structure is arranged between the plate-shaped supporting member and the operating table, and the guiding structure includes a guiding sub-member and a guiding mother-member which are mutually adapted. The guiding sub-member is arranged on the plate-shaped supporting member, the guiding mother-member is arranged on the operating table, and the guiding sub-member can vertically slide relative to the guiding mother-member; the number of the guiding structures is the same and is greater than or equal to two, and the axes of all the guiding structures are not in the same plane.

[0016] By adopting the above technical solution, the guiding structure can reduce the lateral movement amplitude of the plate-shaped supporting member when it is jacked up, and the lateral movement range of the plate-shaped supporting member is limited by three or more guiding structures, so as to improve the alignment accuracy of the sealing rubber ring and the outer shape of the pole hole of the battery cover plate and improve the airtightness at the battery pole.

[0017] Preferably, the guiding mother-member is a guiding sleeve extending vertically downward along the surface of the operating table, and the guiding sub-member is a guiding post extending vertically downward along the lower end surface of the plate-shaped supporting member.

[0018] By adopting the above technical solution, the guiding structure includes a guiding sleeve and a guiding post; before the plate-shaped support is jacked up, its lower end surface is in contact with the operating table surface, which can ensure that the starting position of the plate-shaped supporting member is parallel to the horizontal plane.

[0019] Preferably, a limiting member adapted to the outer shape of the battery cover plate is arranged on the plate-shaped supporting member, and the limiting member is provided with a protruding roller along the end close to the battery cover plate, and the roller can roll relative to the battery cover plate when contacting the battery cover plate.

[0020] By adopting the above technical solution, the limiting member plays a limiting role on the battery cover plate, preventing the battery cover plate from moving horizontally under the influence of external force. When the battery cover plate contacts the rollers on the limiting member, rolling friction is generated, which can reduce the wear of the limiting member and the battery cover plate.

[0021] Preferably, two sealing rubber rings can be placed at the material taking position at the same time, and the distance between the two sealing rubber rings is adapted to the distance between the two pole holes on the battery cover plate.

[0022] By adopting the above technical solution, the distance is the distance between the two pole holes on the battery cover plate; it is more convenient for the adsorption feeding device to take materials, and at the same time, the sealing rubber ring can be limited during material taking, improving the alignment accuracy of the outer shape of the sealing rubber ring and the pole holes of the battery cover plate, and improving the airtightness at the battery poles.

[0023] In a second aspect, the present application provides a method for assembling a sealing rubber ring for a battery cover plate, adopting the following technical solution:

[0024] A method for assembling a sealing rubber ring for a battery cover plate includes:

[0025] S1: Place two sealing rubber rings at the material taking position;

[0026] S2: The total driving device drives the adsorption feeding device to move to a position coinciding with the material taking position, and the ejecting and limiting structure extends along the adsorption end face to provide negative pressure for the adsorption contact member so that the adsorption end face adsorbs the sealing rubber ring;

[0027] S3: The conveying device drives the plate-shaped supporting member with the battery cover plate to coincide with the alignment station;

[0028] S4: The total driving device drives the adsorption feeding device to move to a position coinciding with the alignment station. At this time, the ejecting and limiting structure is inserted into the pole holes of the battery cover plate;

[0029] S5: Stop providing negative pressure for the adsorption contact member so that the adsorption end face stops adsorbing the sealing rubber ring, and the ejecting and limiting structure retracts along the adsorption end face..

[0030] By adopting the above technical solution, the adsorption feeding device can accurately align the sealing rubber ring with the pole holes of the battery cover plate through the ejecting and limiting structure.

[0031] Preferably, in step S3, it further includes: after the plate-shaped supporting member coincides with the alignment station, the jacking device jacks up the plate-shaped supporting member at the alignment station to the working height;

[0032] It further includes step S6: The jacking device moves down to the initial position.

[0033] By adopting the above technical solution, when the adsorption loading device places the sealing rubber ring on the battery cover, the lifting device supports the plate-type supporting member, so that the operating table will not be subjected to pressure and the plate-type supporting member will not tilt, thereby improving the alignment accuracy of the sealing rubber ring and the shape of the battery cover pole hole, and improving the airtightness at the battery pole.

DETAILED DESCRIPTION

[0043] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0044] There will inevitably be a certain gap when the battery cover plate and the battery terminal post are fitted together, which will affect the airtightness of the battery. To ensure good airtightness of the battery, the manufacturer will set a sealing rubber ring adapted to the terminal post hole of the battery cover plate at the terminal post hole of the battery cover plate to fill the above gap. To better fill the above gap, the following method is adopted for the cooperation between the sealing rubber ring and the battery cover plate: a positioning convex ring adapted to the sealing rubber ring is provided at the end face of the battery cover plate in contact with the sealing rubber ring at the terminal post hole, and a concave ring adapted to the positioning convex ring is provided at one end face of the sealing rubber ring. Through the cooperation of the concave ring and the convex ring, the sealing rubber ring and the battery cover plate can be more accurately positioned. At the same time, the contact area between the sealing rubber ring and the battery cover plate can also be increased, thereby improving the airtightness at the battery terminal post.

[0045] For the above-mentioned sealing rubber ring, since there is a concave ring inside, it is more likely to deform when subjected to tangential stress. Therefore, when using a conventional pneumatic adsorption manipulator to adsorb the sealing rubber ring, the above-mentioned sealing rubber ring is likely to deform to a greater extent, resulting in a large error when the sealing rubber ring is positioned with the battery cover plate.

[0046] The embodiment of the present application discloses a sealing rubber ring assembling device for a battery cover plate.

[0047] Refer to Figure 1 As shown in the figure, a sealing rubber ring assembling device for a battery cover plate includes an operating table 1, a conveying device 2, an adsorption feeding device 4, a feeding device 3, a total driving device 5, a material taking place 9, a plate-shaped supporting member 7 and a jacking device 8. Among them, the conveying device 2, the adsorption feeding device 4, the feeding device 3, the total driving device 5, the material taking place 9, the plate-shaped supporting member 7 and the jacking device 8 are arranged on the operating table 1.

[0048] Refer to Figure 1 As shown in the figure, specifically, a positioning station 6 is further arranged on the operating table 1, and the positioning station 6 is used for aligning the sealing rubber ring with the terminal post hole of the battery cover plate. The conveying device 2 is a turntable, and the turntable is rotationally connected to the operating table 1 through a central rotating shaft. The plate-shaped supporting member 7 is arranged on the upper end surface of the turntable and is circumferentially equidistantly distributed along the axis direction of the turntable rotating shaft. The turntable can drive the plate-shaped supporting member 7 to coincide or be misaligned with the positioning station 6.

[0049] Refer to Figure 1 As shown in the figure, the feeding device 3 includes a conveyor belt 31, a motor-driven lead screw guiding structure 32 and a material placing plate 33.

When the motor drives the lead screw to rotate, it can drive the slider to drive the material placing plate 33 to coincide or be misaligned with the material taking place 9.

[0050] Refer to Figure 1, a conveyor belt 31 is provided on the operating table 1, and the conveying direction is perpendicular to the extending direction of the above-mentioned screw rod guiding structure 32; the starting end of the conveyor belt 31 is connected to a vibrating disk, and the vibrating disk sends the sealing rubber ring with the end face provided with a concave ring facing downwards onto the conveyor belt 31; the end of the conveyor belt 31 is connected to the material taking place 9, and a number of protruding columns with a spacing adapted to the outer diameter of the sealing rubber ring are provided on the conveyor belt 31; when the material placing plate 33 moves along the screw rod guiding structure 32 to the material placing groove 331 in contact with the end of the conveyor belt 31, the conveyor belt 31 moves a distance equal to the outer diameter of a sealing rubber ring, and the protruding columns push the sealing rubber ring onto the material placing groove 331; when the conveyor belt 31 pushes two sealing rubber rings onto the two material placing grooves 331 of the material placing plate 33 respectively, one feeding process is completed.

[0051] Refer to Figure 1-2 , the total driving device 5 includes a first driving device 51 and a laterally sliding track 52 driven by a motor, which is used to drive the adsorption feeding device 4 to move relative to the operating table 1 in the horizontal and vertical directions. Specifically, the central rotating shaft is fixedly connected to the operating table 1, and an installation table 11 is provided on the central rotating shaft. The tabletop of the installation table 11 is higher than the upper end face of the turntable; the laterally sliding track 52 is provided on the installation table 11, and the laterally sliding track 52 is a screw rod guiding structure 32. The adsorption feeding device 4 is vertically slidably connected to the slider on the screw rod guiding structure 32; the motor drives the screw rod to rotate, which can drive the slider to drive the adsorption feeding device 4 to coincide or be misaligned with the material taking place 9 and the alignment station 6 respectively from a top view angle.

[0052] Refer to Figure 2 and 4 , in addition, the first driving device 51 is fixedly connected to the slider of the adsorption feeding device 4; the first driving device 51 is a cylinder, which is used to drive the adsorption feeding device 4 to move vertically; the adsorption feeding device 4 includes an adsorption contact member 41, a second driving device 414 and an ejection limiting structure 413; among them, the adsorption contact member 41 includes a frame 411 and an air vent block 412 connected to a vacuum generator. The frame 411 is connected to the piston rod of the first driving device 51. The air vent block 412 connected to the vacuum generator and the second driving device 414 are both provided on the frame 411. The air vent block 412 connected to the vacuum generator is provided with an adsorption end face 4121, and the adsorption end face 4121 is used to adsorb the sealing rubber ring along the upper end face of the sealing rubber ring. A perforation adapted to the outer diameter of the ejection limiting structure 413 is provided in the middle of the air vent block 412 connected to the vacuum generator; the ejection limiting structure 413 is a cylinder with an outer diameter adapted to the inner diameter of the sealing rubber ring, and is vertically slidably connected to the frame 411, and can extend or retract along the adsorption end face 4121 of the air vent block 412 connected to the vacuum generator. There are two ejection limiting structures 413, and the distance between the two ejection limiting structures 413 is the distance between the two pole column holes of the battery cover; the second driving device 414 is a cylinder, which is used to drive the ejection limiting structure 413 to move vertically.

[0053] Refer toFigure 2 and 4 In addition, the lifting device 8 is located below the turntable, and the lifting device 8 overlaps with the operating station in the top view; the lifting device 8 is vertically slidably connected to the operating table 1, driven by the cylinder, and used to lift the plate-type supporting member 7. Specifically, the lifting device 8 is a block-shaped body whose lower end face is connected to the cylinder, and the upper end face of the lifting device 8 is provided with two lifting columns with a spacing equal to the spacing of the battery cover plate poles. The turntable is provided with a clearance hole 21 at the position corresponding to the battery cover plate pole on the plate-type supporting member 7, and the inner diameter of the clearance hole 21 is adapted to the inner diameter of the lifting column; the lifting column can lift the plate-type supporting member 7 located at the operating station through the clearance hole 21. During the placement of the sealing rubber ring, the plate-type supporting member 7 is subjected to pressure and support force at the battery cover plate pole, which is more stable.

[0054] Reference Figure 1 and 3 A guide structure is also provided between the plate-type supporting member 7 and the turntable, and there are four guide structures, which are respectively arranged at the four top corners of the plate-type supporting member 7; the guide structure includes mutually adapted guide sub-members and guide mother members, wherein the guide sub-member is a guide column 72 arranged on the plate-type supporting member 7, and the guide mother member is a guide sleeve 22 arranged on the turntable; the guide column 72 extends downward along the lower end surface of the plate-type supporting member 7, and the guide sleeve 22 extends downward along the surface of the operating table 1; through the cooperation of the guide sleeve 22 and the guide column 72, the plate-type supporting member 7 is reduced in the horizontal direction when it is lifted up, so that the alignment accuracy of the sealing rubber ring and the shape of the battery cover plate pole hole is improved.

[0055] Reference Figure 1 and 3 The plate supporting member 7 and the turntable member are also provided with a height limiting bolt 71, which is connected to the upper end surface of the turntable by a thread. The plate supporting member 7 is provided with a through hole for the height limiting bolt 71 to pass through, and the aperture of the through hole is smaller than the diameter of the nut of the height limiting bolt 71; when the plate supporting member 7 is lifted to the maximum height, the upper end surface of the plate supporting member 7 contacts the lower end surface of the nut of the height limiting bolt 71. The above structure ensures that the plate supporting member 7 works at the same height each time, which can prevent the gap between the adsorption end surface 4121 and the upper end surface of the battery cover plate from being too small, resulting in the sealing rubber ring being squeezed and deformed, or the gap from being too large, resulting in assembly errors.

[0056] Reference Figure 1 and 3 A limiting member 73 is also provided on the plate-type supporting member 7. The limiting member 73 is a plurality of limiting blocks evenly distributed along the outer contour of the battery cover. A protruding roller 731 is provided on the side of the limiting block close to the battery cover. When the battery cover contacts the roller 731, rolling friction is generated, thereby reducing the wear of the battery cover and the limiting block when they contact.

[0057] In summary, in this solution, the sealing rubber ring is limited by the ejection limit structure 413 and the blanking plate 33, and the battery cover plate is limited by the limiting member 73 on the plate-shaped supporting member 7. At the same time, by using the lifting device 8 to lift the plate-shaped supporting member 7, the possibility of the turntable being tilted due to frequent stress is reduced, thereby reducing the tilting degree of the battery cover plate. The plate-shaped supporting member 7 is limited by the guiding structure and the height-limiting bolt 71, thereby improving the alignment accuracy between the sealing rubber ring and the outer shape of the pole hole of the battery cover plate and improving the airtightness at the battery pole.

[0058] The implementation principle of the sealing rubber ring assembling device for the battery cover plate in the embodiment of the present application is as follows: The adsorption feeding device 4 moves horizontally to the position coinciding with the material taking place 9 in the top view direction, and then moves down to the position where the adsorption end face 4121 coincides with the upper end face of the sealing rubber ring. The sealing rubber ring is adsorbed through the adsorption end face 4121. The ejection limit structure 413 extends from the adsorption end face 4121 to limit the sealing rubber ring, and the adsorption feeding device 4 moves up and resets. The adsorption feeding device 4 moves horizontally to the position coinciding with the alignment station 6 in the top view direction and moves down. The lifting device 8 lifts the plate-shaped supporting member 7 located at the alignment station 6 to the maximum height, and the sealing rubber ring cooperates with the battery cover plate. The air vent block 412 connected with the vacuum generator on the adsorption feeding device 4 stops sucking air, and the ejection limit structure 413 retracts along the adsorption end face 4121.

[0059] The embodiment of the present application also discloses a method for assembling the sealing rubber ring for the battery cover plate.

[0061] S1: Place two sealing rubber rings at the material taking place 9;

[0062] S2: The total driving device 5 drives the adsorption feeding device 4 to move to the position coinciding with the material taking place 9, the ejection limit structure 413 extends along the adsorption end face 4121, and the adsorption end face 4121 adsorbs the sealing rubber ring;

[0063] S3: The conveying device 2 drives the plate-shaped supporting member 7 equipped with the battery cover plate to coincide with the alignment station 6; the lifting device 8 lifts the plate-shaped supporting member 7 at the alignment station 6 to the working height, and the upper end face of the plate-shaped supporting member 7 contacts the lower end face of the nut of the height-limiting bolt 71;

[0064] S4: The total driving device 5 drives the adsorption feeding device 4 to move to the position coinciding with the alignment station 6. At the same time, the ejection limit structure 413 is inserted into the pole hole of the battery cover plate;

[0065] S5: The adsorption end face 4121 stops adsorbing the sealing rubber ring, and the ejection limit structure 413 retracts along the adsorption end face 4121.

[0066] S6: The jacking device 8 resets, driving the plate-shaped supporting member 7 to reset.

[0067] The implementation principle of the method for assembling the sealing rubber ring for the battery cover plate in the embodiment of the present application is as follows: When the adsorption feeding device 4 places the sealing rubber ring on the battery cover plate, the jacking device 8 supports the plate-shaped supporting member 7, so that the operating table 1 will not be under pressure and the plate-shaped supporting member 7 will not tilt, improving the alignment accuracy of the sealing rubber ring with the outer shape of the battery cover plate pole hole and improving the airtightness at the battery pole.

[0068] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
