Description

Technical Field

[0001] The invention belongs to the technical field of electrode sheet cleaning, and in particular relates to an electrode sheet cleaning device for lithium battery production. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, were born in 1996. Their safety, specific capacity, self-discharge rate, and performance-price ratio are superior to lithium-ion batteries. Due to their own high technical requirements, only companies in a few countries are producing such lithium metal batteries.

[0003] The electrode sheets need to be cleaned on the surface during the production process. Before assembly, workers clean the impurities on the surface of the electrode sheets. Metal chips and other impurities on the surface of the electrode sheets can easily affect the power supply of lithium batteries. The existing cleaning method is usually to clean them manually with a brush. This method will cause dust and metal chips to splash during cleaning, and then fall naturally. If they are not cleaned for a long time, it will affect the quality of the workers' working environment. Manually cleaning the electrode sheets one by one will undoubtedly increase the workers' labor. Summary of the Invention

[0004] In order to solve the problem that the electrode sheets proposed in the above background technology need to be cleaned on the surface during the production process, workers clean the impurities on the surface of the electrode sheets before assembly. The metal chips and other impurities on the surface of the electrode sheets can easily affect the power supply of the lithium battery. The existing cleaning method is usually to clean manually with a brush. This method will cause dust and metal chips to splash during cleaning, and then fall naturally. If they are not cleaned for a long time, it will affect the quality of the workers' working environment.

[0007] Preferably, a group of oppositely symmetrical tooth plates are fixedly connected to the outer walls on both sides of the other end of the push plate, and two rectangular grooves are also provided on both sides of the push plate.

[0008] Preferably, two groups of rotating rods are movably sleeved in the inner wall of the top end of the cleaning box plate, and the two groups of rotating rods are fixedly connected with spur gears. One side wall of the two groups of spur gears is intermittently meshed with one side wall of the two groups of tooth plates respectively. The two groups of rotating rods are also fixedly connected with brush cylinders, and the two groups of brush cylinders are respectively connected to the corresponding inner walls at both ends of the two rectangular grooves in a fitting and rotatable manner.

[0009] Preferably, a support plate is fixedly connected to the outer wall of one side of the top end of the two long plates, two springs are fixedly connected to the outer wall of one end of the support plate, and the other ends of the two springs are fixedly connected to the outer wall of one end of the push plate.

[0010] Preferably, a T-shaped slide groove three is provided on the inner wall of one side of the bottom end of the two long boards, a ball groove is provided in the inner wall of one end of the two T-shaped slide grooves three, a T-shaped slider three is slidably engaged in the inner wall of the two T-shaped slide grooves three, a locking ball is fixedly connected to the outer wall of one end of the two T-shaped sliders three, and the two locking balls are intermittently fitted and engaged with the inner walls of the two ball grooves.

[0011] Preferably, the bottom ends of the two T-shaped slide grooves are jointly and fixedly connected with a dust box, the outer wall of one end of the dust box is fitted with the outer wall of one end of the cleaning box plate, and the other end of the dust box can be intermittently and tightly clamped with a box plug.

[0012] Preferably, a plurality of bellows can be passed through and tightly connected on the inner and outer walls of one end of the dust collecting box, and a section of the tube body of each of the bellows is specifically made of a hard material. A U-shaped support plate is fixedly connected to the outer wall of the top end of a section of the multiple bellows, and both ends of the U-shaped support plate are respectively fixedly connected to the outer walls of the bottom ends of the two long strips, and the bottom end of each section of the tube body is passed through and fixedly connected with a dust suction pipe.

[0013] Preferably, each of the dust suction pipes is fixedly connected to a one-way valve for controlling the one-way flow of gas.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention enables a worker to pull a push-pull rod to drive the push plate to move, and then pulls the two springs on the support plate to deform it. The passively moving push plate can be guided horizontally in the corresponding T-shaped slide groove one and T-shaped slide groove two by means of T-shaped sliders 1 and 2 respectively installed on both sides of the bottom end and the left and right ends. This makes it easy for a worker to clamp the electrode sheet to be cleaned into the clamping groove, and tightly clamp it without damage through a pair of rubber pads in the clamping groove. After the worker releases the push-pull rod and no longer pulls the spring, the two sets of tooth plates on the push plate can be contacted and meshed with the two sets of spur gears in turn, thereby driving the two sets of spur gears, the rotating rod, and the brush cylinder to rotate in turn, and the rotating brush cylinder can clean the outer walls of the two ends of the clamped and moved electrode sheet.

[0017] The present invention causes the push plate to move when a worker pulls the push-pull rod, and simultaneously drives the multiple bellows connected by the L-shaped slot plate to move horizontally. The multiple bellows that are pulled and moved horizontally will generate suction force at the same time, and then the dust and metal chips of the electrode sheets generated after the cleaning box plate has been cleaned in advance will be sucked out through the dust suction pipe installed at one end. The sucked-in dust and metal chips will all enter the dust box, and the one-way valves respectively installed on the multiple bellows can make the sucked-in dust and metal chips only enter but not exit. Finally, the two T-shaped sliders three and the card ball installed on the top of the dust box are respectively disengaged from the T-shaped slide groove three and the ball groove, thereby also separating from the multiple bellows. Subsequently, the box plug can be taken out from the dust box by the worker, and the dust and metal chips in the dust box can be quickly cleaned uniformly. The above can improve the cleaning efficiency of the electrode sheet surface and keep the cleaning environment tidy. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 8 As shown, the present invention provides an electrode sheet cleaning device for lithium battery production, including a cleaning box plate 1, wherein long strips 11 are fixedly connected to the inner walls at both ends of the cleaning box plate 1, and a T-shaped slide groove 12 is provided in the top of the two long strips 11, and a push plate 13 is also slidably connected to the inner walls at both ends of the cleaning box plate 1, and a T-shaped slider 14 is fixedly connected to the outer walls on both sides of the bottom end of the push plate 13, and the two T-shaped sliders 14 are respectively slidably engaged with the inner walls of the two T-shaped slide grooves 12, and T-shaped sliders 2 15 are also fixedly connected to the outer walls at both ends of the push plate 13, and T-shaped slide grooves 2 16 are provided in the inner walls at both ends of the cleaning box plate 1, and the two T-shaped sliders 2 15 are respectively slidably engaged with the two T-shaped slide grooves 2 16.

[0030] By adopting the above scheme, the passively movable push plate 13 can be guided horizontally in the corresponding T-shaped slide groove 12 and T-shaped slide groove 2 16 through the T-shaped slider 14 and T-shaped slider 2 15 installed on both sides of the bottom end and the left and right ends respectively.

[0031] There are two slots 17 running through the push plate 13. The inner walls at both ends of the two slots 17 are fixedly connected with rubber pads 18. The two sets of rubber pads 18 are used to clamp the electrode sheet to be cleaned without damage. A push-pull rod 19 is fixedly connected to the outer wall of the center of one end of the push plate 13. A set of oppositely symmetrical tooth plates 120 are fixedly connected to the outer walls on both sides of the other end of the push plate 13. Two rectangular grooves are also run through on both sides of the push plate 13. Two sets of rotating rods 122 are movably sleeved in the inner wall of the top of the cleaning box plate 1. The two sets of rotating rods 122 are fixedly connected The spur gear 121 and one side wall of the two groups of spur gears 121 are intermittently meshed with one side wall of the two groups of tooth plates 120, and the two groups of rotating rods 122 are also fixedly connected with a brush cylinder 123. The two groups of brush cylinders 123 are respectively connected to the corresponding inner walls at both ends of the two rectangular grooves. A push plate 124 is fixedly connected to the outer wall of one side of the top of the two long strips 11, and two springs 125 are fixedly connected to the outer wall of one end of the push plate 124. The other ends of the two springs 125 are fixedly connected to the outer wall of one end of the push plate 13.

[0032] The above scheme is adopted: the worker pulls the push-pull rod 19 to drive the push plate 13 to move, and then pulls the two springs 125 on the support plate 124 to cause it to deform. The worker clamps the electrode piece to be cleaned into the slot 17, and uses a pair of rubber pads 18 in the slot 17 to clamp it tightly without damage. Subsequently, the worker loosens the push-pull rod 19 and no longer pulls the spring 125, so that the push plate 13 is reset under the drive of the spring 125, and then driven by the reset of the spring 125, the two sets of tooth plates 120 on the push plate 13 can contact and engage with the two sets of spur gears 121 in turn, thereby driving the two sets of spur gears 121, the rotating rod 122, and the brush cylinder 123 to rotate in turn, and the rotating brush cylinder 123 is used to clean the outer walls of the clamped and moved electrode pieces.

[0033] A T-shaped slide groove three 126 is provided on the inner wall of one side of the bottom end of the two long boards 11, and a ball groove 127 is provided in the inner wall of one end of the two T-shaped slide grooves three 126. A T-shaped slider three 128 is slidably engaged in the inner wall of the two T-shaped slide grooves three 126, and a card ball 129 is fixedly connected to the outer wall of one end of the two T-shaped sliders three 128. The two card balls 129 are intermittently fit and engage with the inner walls of the two ball grooves 127. The bottom ends of the two T-shaped slide grooves three 126 are jointly and fixedly connected to the dust box 130, and the outer wall of one end of the dust box 130 is fitly connected to the outer wall of one end of the cleaning box plate 1, and the other end of the dust box 130 is intermittently and tightly engaged with a box plug 131.

[0034] The above solution is adopted: after the two T-shaped sliders 128 and the card ball 129 installed on the top of the dust box 130 are disengaged from the T-shaped slide groove 126 and the ball groove 127 respectively, they are also separated from the multiple bellows 132. Subsequently, the box plug 131 can be taken out of the dust box 130 by a worker, and the dust and metal chips in the dust box 130 can be quickly cleaned up.

[0035] A plurality of bellows 132 can be passed through and tightly connected on the inner and outer walls of one end of the dust collecting box 130. A section of the tube body of each bellows 132 is specifically made of a hard material. A U-shaped support plate is fixedly connected to the outer wall of a section of the top end of the plurality of bellows 132. Both ends of the U-shaped support plate are respectively fixedly connected to the outer wall of the bottom end of the two long plates 11, and the bottom end of each section of the tube body is passed through and fixedly connected with a dust suction pipe 133. Each dust suction pipe 133 is fixedly connected with a one-way valve 134 for controlling the one-way flow of gas. One end of each bellows 132 is jointly and fixedly connected with an L-shaped groove plate 135. The outer wall of one end of the L-shaped groove plate 135 is fixedly connected to the outer wall of one end of the push plate 13 near the bottom end, and the outer walls of both ends of the L-shaped groove plate 135 are respectively fitted and slidably connected to the outer wall of one end of the two long plates 11.

[0036] The above scheme is adopted: when the worker pulls the push-pull rod 19 to drive the push plate 13 to move, it will also synchronously drive the multiple bellows 132 connected by the L-shaped groove plate 135 to move horizontally. The multiple bellows 132 that are pulled and translated will generate suction force at the same time, and then the dust and metal chips of the electrode sheets generated after the cleaning of the cleaning box plate 1 in advance will be sucked through the dust suction pipe 133 installed on one end. The sucked-away dust and metal chips will enter the dust collecting box 130 in a unified manner. When the push plate 13 moves and squeezes the multiple bellows 132, the one-way valves 134 respectively installed on the multiple bellows 132 can prevent the sucked-in dust and metal chips from entering but not exiting.

[0037] The working principle and use process of the present invention are as follows: the worker pulls the push-pull rod 19 to drive the push plate 13 to move, and then pulls the two springs 125 on the abutment plate 124 to deform it. The passively moving push plate 13 can be guided horizontally in the corresponding T-shaped chute 12 and T-shaped chute 2 16 through the T-shaped slider 14 and T-shaped slider 2 15 installed on both sides of the bottom and the left and right ends, thereby making it easier for the worker to clamp the electrode sheet to be cleaned into the clamping slot 17, and the pair of rubber pads 18 in the clamping slot 17 can clamp it tightly without damaging it. Then, the worker releases the push-pull rod 19 and no longer pulls the spring 125, so that the push plate 13 is reset under the drive of the spring 125. Then, under the reset drive of the spring 125, the two sets of tooth plates 120 on the push plate 13 can be contacted and engaged with the two sets of spur gears 121 in turn, thereby driving the two sets of spur gears 121 and the rotating rod 122 to rotate in turn. When each rotating rod 122 is passively rotated, it will also synchronously drive the corresponding brush cylinder 123 to rotate, and the rotating brush cylinder 123 is used to clean the outer walls of both ends of the clamped and moved electrode sheet;

[0038] When the worker pulls the push-pull rod 19 to drive the push plate 13 to move, the multiple bellows 132 connected by the L-shaped groove plate 135 will be synchronously driven to move horizontally. The multiple bellows 132 that are pulled and moved horizontally will generate suction force at the same time, and then the dust and metal chips generated by the electrode sheet that have been cleaned in the cleaning box plate 1 in advance will be sucked through the dust suction pipe 133 installed at one end. The sucked dust and metal chips will be uniformly put into the dust collecting box 130. When the push plate 13 is subsequently moved and squeezed to the multiple bellows 132, the dust and metal chips will be separated and discharged through the multiple bellows 132. The separately installed one-way valve 134 can make the sucked-in dust and metal chips only go in but not out. Finally, the two T-shaped sliders 128 and the card ball 129 installed on the top of the dust box 130 are disengaged from the T-shaped slide groove 126 and the ball groove 127 respectively, thereby also separating from the multiple bellows 132. Subsequently, workers can take out the box plug 131 from the dust box 130, and the dust and metal chips in the dust box 130 can be quickly cleaned up. The above can improve the cleaning efficiency of the electrode surface and keep the cleaning environment tidy.
