[0001] This invention relates to the field of power battery cell production technology, specifically to a power battery cell production equipment. Background Technology

[0002] A power battery cell is the core component of a power battery, and it is a module composed of multiple battery cells. Each battery cell is an independent battery, typically a lithium-ion battery or a lithium cobalt oxide battery. During the production process of power batteries, specialized punching equipment is usually used to punch holes in the tabs, which ensures that the tabs have good conductivity and connectivity.

[0003] In the prior art, punching equipment is generally used to directly punch holes in the tabs. However, since the tabs of the battery cell are made of soft materials, they are prone to bending. If they are punched directly, the punching position will be inaccurate, which will reduce the quality of the product and affect the service life of the power battery. Therefore, the present invention provides a power battery cell production equipment. Summary of the Invention

[0004] The technical problem solved by this invention is: In the prior art, punching equipment is generally used to directly punch holes in the tabs. However, since the tabs of the battery cell are made of soft materials, they are prone to bending. If they are punched directly, the punching position will be inaccurate, which will reduce the quality of the product and thus affect the service life of the power battery.

[0005] This invention can be achieved through the following technical solution: a power battery cell production equipment, including a base, two support plates symmetrically fixed to the top of the base, a punching platform fixed to the center of the top of the base, a first U-shaped frame fixed between the two support plates, a second U-shaped frame slidably connected to the inner wall of the first U-shaped frame, a threaded rod and a guide rod arranged parallel to each other on the inner wall of the first U-shaped frame, the threaded rod being rotatably connected to the inner wall of the first U-shaped frame and passing through the second U-shaped frame, the guide rod being fixed to the inner wall of the first U-shaped frame and passing through the second U-shaped frame, and a pressing roller being rotatably connected to the bottom of the second U-shaped frame.

[0006] A further technical improvement of the present invention is that: a rod is slidably connected through the top of the first U-shaped frame, and a fixing frame is fixedly connected to the bottom end of the rod.

[0007] A further technical improvement of the present invention is that: a first spring is fixedly connected between the top of the fixed frame and the lower side of the top of the first U-shaped frame; a trapezoidal through groove is opened at one end of the first rod located at the top of the first U-shaped frame; a rack is slidably connected to the top of the first U-shaped frame; a triangular block is fixedly connected to one end of the rack; and the triangular block and the trapezoidal through groove are slidably engaged.

[0008] A further technical improvement of the present invention is that: a second rod is slidably connected through the left side of the first U-shaped frame, the second rod is fixedly connected to the rack by a strip plate, a second spring is fixedly connected to the side of the strip plate away from the first U-shaped frame, and the other end of the second spring is fixedly connected to the side wall of the support plate.

[0009] A further technical improvement of the present invention is that: a third rod is slidably connected through the top of the first U-shaped frame, the third rod is driven by an electric cylinder, and a punch is fixedly connected to the bottom end of the third rod.

[0010] A further technical improvement of the present invention is that: a fourth rod is rotatably connected through the top of the first U-shaped frame, a gear is sleeved and fixedly connected to the top of the fourth rod, the gear is meshed with the rack, a push plate is fixedly connected to the bottom of the fourth rod, and an adhesive coating is provided on the top of the push plate.

[0011] A further technical improvement of the present invention is that: a positioning groove is provided on the top of the punching platform, and a through groove is provided in the positioning groove to cooperate with the downward movement of the punch.

[0012] A further technical improvement of the present invention is that: the bottom of the through groove extends all the way to the bottom of the base, a No. 5 rod is rotatably connected in the through groove, and multiple levers are fixedly connected to the outside of the No. 5 rod, and the multiple levers surround the outer periphery of the No. 5 rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this invention, after the battery cell tab is placed in the positioning groove, the motor drives the threaded rod to rotate, which in turn drives the second U-shaped frame to move horizontally. The second U-shaped frame drives the pressing roller to roll on the top of the battery cell tab, thereby rolling the battery cell tab and flattening it, preventing the battery cell tab from bending and folding, and thus preventing the punching position from shifting and ensuring the punching effect of the battery cell tab.

[0015] 2. In this invention, when the second U-shaped frame drives the pressing roller to move to the left, it will cause the second U-shaped frame to squeeze the second rod, and finally the triangular block will leave the trapezoidal through groove. At this time, the first rod will move downward under the elastic force of the first spring, thereby squeezing the battery cell tab and fixing the battery cell tab, thus preventing the position of the battery cell tab from shifting when punching the battery cell tab.

[0016] 3. In this invention, when the second U-shaped frame drives the pressing roller to move to the left, the rack will drive the triangular block to move to the left. At this time, the rack drives the gear to rotate, causing the fourth rod to drive the push plate to rotate slightly. When the top of the push plate contacts the bottom of the punch, the adhesive coating on the top of the push plate will be adsorbed on the bottom of the punch. When the punch punches the battery cell tab, the punched waste will stick to the bottom of the punch, avoiding the waste from clogging the through groove during punching, making it convenient to collect the waste and clean the through groove.

[0023] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0024] Please see Figures 1-4As shown, a power battery cell production equipment includes a base 1. Two support plates 2 are symmetrically fixed to the top of the base 1. A first U-shaped frame 3 is fixed between the two support plates 2. A third rod 4 is slidably connected through the top of the first U-shaped frame 3. The third rod 4 is driven by an electric cylinder, which is fixedly installed on the top of the first U-shaped frame 3. A punch 5 is fixed to the bottom end of the third rod 4. A punching platform 6 is fixed at the center of the top of the base 1. A positioning groove 7 is opened on the top of the punching platform 6, and a through groove 8 is opened in the positioning groove 7 to cooperate with the downward movement of the punch 5. During operation, the battery cell tab is placed in the positioning groove 7, and then the electric cylinder is started, so that the electric cylinder drives the third rod 4 and the punch 5 to move downward, thereby punching the battery cell tab.

[0025] Furthermore, to achieve leveling of the battery cell tabs placed in the positioning groove 7, a second U-shaped frame 9 is slidably connected to the inner wall of the first U-shaped frame 3. A threaded rod 10 and a guide rod 11 are also parallelly arranged on the inner wall of the first U-shaped frame 3. The threaded rod 10 is rotatably connected to the inner wall of the first U-shaped frame 3 and passes through the second U-shaped frame 9. The guide rod 11 is fixed to the inner wall of the first U-shaped frame 3 and passes through the second U-shaped frame 9. A pressing roller 12 is rotatably connected to the bottom of the second U-shaped frame 9. The outer side of the second U-shaped frame 9... A motor is fixedly installed on the wall, and the output shaft of the motor is fixedly connected to one end of the threaded rod 10. When the battery cell tab is placed in the positioning groove 7, the motor is started, which drives the threaded rod 10 to rotate. The threaded rod 10 drives the second U-shaped frame 9 to move horizontally. The second U-shaped frame 9 drives the pressing roller 12 to roll on the top of the battery cell tab, thereby rolling the battery cell tab and flattening it. This prevents the battery cell tab from bending and folding, and thus prevents the punching position from shifting, ensuring the punching effect of the battery cell tab.

[0026] Furthermore, a rod 13 is slidably connected through the top of the first U-shaped frame 3, and a fixing frame 14 is fixedly connected to the bottom end of the rod 13; a first spring 15 is fixedly connected between the top of the fixing frame 14 and the lower side of the top of the first U-shaped frame 3; a trapezoidal through groove 8 is opened at one end of the rod 13 at the top of the first U-shaped frame 3; a rack 16 is slidably connected to the top of the first U-shaped frame 3; a triangular block 17 is fixedly connected to one end of the rack 16; and the triangular block 17 slides between the trapezoidal through groove 8. The first U-shaped frame 3 is slidably connected to the left side of the second rod 18. The second rod 18 is fixed to the rack 16 by the strip plate 19. The side of the strip plate 19 away from the first U-shaped frame 3 is fixed to the second spring 20, and the other end of the second spring 20 is fixed to the side wall of the support plate 2. When the pressing roller 12 is located to the right of the battery cell tab, the triangular block 17 is located to the right of the first rod 13. At this time, the first spring 15 is in a compressed state, and the fixing frame 14 is located at the upper limit position.

[0027] During operation, when the second U-shaped frame 9 drives the pressing roller 12 to move to the left, it will cause the second U-shaped frame 9 to squeeze the second rod 18. This causes the second rod 18 to drive the strip plate 19 and the rack 16 to move to the left, which in turn causes the rack 16 to drive the triangular block 17 to gradually move to the left. Finally, the triangular block 17 leaves the trapezoidal through groove 8. At this time, the second spring 20 is compressed and stores elastic potential energy. Since the rack 16's restriction on the first rod 13 is removed, the first rod 13 will move downward under the elastic force of the first spring 15, thus achieving the desired effect. The extrusion of the battery cell tabs secures them, preventing displacement during punching. After punching, the second U-shaped frame 9 moves the pressing roller 12 to the right back to its initial position. The spring force of the second spring 20 causes the strip plate 19 and rack 16 to move to the right, which in turn causes the triangular block 17 to press the trapezoidal groove 8, causing the first rod 13 to move upward, which in turn causes the fixing frame 14 to move upward, making it easier to remove the battery cell tabs from the positioning groove 7.

[0028] Furthermore, the top of the first U-shaped frame 3 is also connected to a fourth rod 21, which is rotatably connected to the top of the fourth rod 21. A gear 22 is fitted and fixed to the top of the fourth rod 21, and the gear 22 is meshed with the rack 16. A push plate 23 is fixed to the bottom of the fourth rod 21, and the top of the push plate 23 is coated with an adhesive coating. When the second U-shaped frame 9 drives the pressing roller 12 to move to the left, the second U-shaped frame 9 will squeeze the second rod 18, causing the second rod 18 to drive the strip plate 19 and the rack 16 to move to the left. This causes the rack 16 to drive the triangular block 17 to gradually move to the left. At this time, the rack 16 drives the gear 22 to rotate, causing the fourth rod 21 to drive the push plate 23 to rotate slightly. When the top of the push plate 23 contacts the bottom of the punch 5, the push plate 23... The adhesive coating on the top of the punch 5 will adhere to the bottom of the punch 5. When the punch 5 punches the battery cell tabs, the punched waste will stick to the bottom of the punch 5 and then move upward with the punch 5 to the top and bottom of the first U-shaped frame 3. When the second U-shaped frame 9 drives the pressing roller 12 to move to the right and return to the initial position, the elastic force of the second spring 20 will cause the strip plate 19 and the rack 16 to move to the right, so that the rack 16 and the gear 22 will mesh again, causing the gear 22 to drive the fourth rod 21 to rotate in the opposite direction, thereby causing the push plate 23 to push the waste adhering to the punch 5 away from the punch 5. This avoids the waste from clogging the through groove 8 during punching, making it convenient to collect the waste and clean the through groove 8.

[0029] In the above, the bottom of the through groove 8 extends all the way to the bottom of the base 1. A fifth rod 24 is rotatably connected inside the through groove 8. Multiple levers 25 are fixed to the outside of the fifth rod 24 and surround the fifth rod 24. By rotating the fifth rod 24, the fifth rod 24 drives the levers 25 to rotate, thereby cleaning the inside of the through groove 8, preventing the accumulation of waste inside the through groove 8, and making it easier to clean the through groove 8.

[0030] In use, the battery cell tab is placed in the positioning groove 7, and the motor is started, causing the threaded rod 10 to rotate. The threaded rod 10 then drives the second U-shaped frame 9 to move horizontally. The second U-shaped frame 9 drives the pressing roller 12 to roll on top of the battery cell tab, achieving rolling pressure on the tab and thus leveling it, preventing bending and folding. This prevents displacement of the punching position and ensures the punching effect. When the second U-shaped frame 9 drives the pressing roller 12 to the left, it presses the second rod 18, causing the second rod 18 to drive the strip plate 19 and rack 16 to move to the left. This, in turn, causes the rack 16 to gradually move the triangular block 17 to the left, eventually disengaging the triangular block 17. When the trapezoidal through slot 8 is opened, the second spring 20 is compressed and stores elastic potential energy. Since the rack 16's limit on the first rod 13 is removed, the first rod 13 will move downward under the elastic force of the first spring 15, thereby squeezing the battery cell tab and fixing it, preventing the battery cell tab from shifting position when punching holes. After punching the battery cell tab, the second U-shaped frame 9 drives the pressing roller 12 to move to the right and return to the initial position. Due to the elastic force of the second spring 20, the strip plate 19 and the rack 16 will move to the right, and the triangular block 17 will squeeze the trapezoidal through slot 8, causing the first rod 13 to move upward, thereby causing the fixing frame 14 to move upward, making it easier to remove the battery cell tab from the positioning slot 7.

[0031] When the second U-shaped frame 9 drives the pressing roller 12 to move to the left, it will cause the second U-shaped frame 9 to squeeze the second rod 18, causing the second rod 18 to drive the strip plate 19 and the rack 16 to move to the left. In turn, the rack 16 will drive the triangular block 17 to gradually move to the left. At this time, the rack 16 drives the gear 22 to rotate, causing the fourth rod 21 to drive the push plate 23 to rotate slightly. When the top of the push plate 23 contacts the bottom of the punch 5, the sticky coating on the top of the push plate 23 will be adsorbed onto the bottom of the punch 5. When the punch 5 punches the battery cell tabs, the punched waste will stick to the bottom of the punch 5. Then, along with the punch 5, it moves upward to the top and lower side of the first U-shaped frame 3. When the second U-shaped frame 9 drives the pressing roller 12 to move to the right and return to the initial position, due to the elastic force of the second spring 20, the strip plate 19 and the rack 16 will move to the right, causing the rack 16 and the gear 22 to mesh again, causing the gear 22 to drive the fourth rod 21 to rotate in the opposite direction, thereby causing the push plate 23 to push the waste material adhering to the punch 5 away from the punch 5. This avoids the waste material from clogging the through groove 8 during punching, making it convenient to collect the waste material and clean the through groove 8.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.
