Description

Technical Field

[0001] This utility model relates to the field of wire technology, and in particular to a battery packaging slitting machine. Background Technology

[0002] Batteries have a wide range of applications and play a very important role in people's daily lives. In battery production, multiple batteries need to be packaged side by side to form battery packs. The standard configuration of existing battery packaging lines generally produces battery packs of four. With the diversification of user needs, in addition to the standard four-pack, one-pack, two-pack, or three-packs have also emerged. Therefore, it is necessary to cut the four-pack battery packs into battery packs with the required number of batteries.

[0003] Among existing patents, Chinese patent application number 201920757548.9 discloses a high-efficiency battery packaging four-cell slitting device, including a slitting device, a secondary shrinking device, and a receiving device. The slitting device includes a first conveyor belt, a feeding cylinder, a four-cell battery trough, a slitting blade holder, and a partition. A side plate and a cover plate are provided above the first conveyor belt, and a feeding cylinder is provided at the tail end of the first conveyor belt. The four-cell battery trough, a cutting groove, and a partition slide groove are provided above the cover plate. A slitting blade holder is provided on one side of the side plate, and a slitting blade rod is provided on the slitting blade holder. A slitting blade is provided at one end of the slitting blade rod. A partition is provided in the partition slide groove, and a baffle is provided at the connection between the slitting device and the secondary shrinking device. The secondary shrinking device includes a second conveyor belt, a Y-shaped partition, and a hot air blower. A Y-shaped partition is positioned above the second conveyor belt, with baffles symmetrically arranged at one end of the Y-shaped partition. A hot air blower is positioned above the Y-shaped partition. The receiving device includes two battery receiving troughs, a baffle block, a top-feeding cylinder, a top-feeding plate bracket, a top-feeding plate, a buffer plate, and a buffer damper. The two battery receiving troughs are symmetrically arranged on both sides of the Y-shaped partition. A baffle block and a top-feeding plate groove are provided in each of the two battery receiving troughs. A buffer damper is provided at the tail end of each of the two battery receiving troughs, with a buffer plate at one end of the buffer damper. A top-feeding cylinder is positioned below the two battery receiving troughs, with a top-feeding plate bracket at one end of the top-feeding cylinder, and a top-feeding plate is mounted on the top-feeding plate bracket. Although the patent document describes a process where a slitting device cuts four-section shrink-packaged batteries into two sections, a secondary shrinking device shrinks the cut PVC film a second time, and a top plate in the receiving device can lift two heat-shrinked batteries lying in the slot and arrange them vertically for easy removal of multiple batteries by employees, the receiving device uses a top cylinder and a top plate to lift the batteries vertically, and a buffer plate blocks the vertically arranged batteries. Therefore, the batteries can only be arranged vertically in a fixed position for employees to take away, and it is impossible to continue to transport the vertically arranged batteries.

[0004] Therefore, the defects are very obvious, and a solution is urgently needed. Utility Model Content

[0005] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a battery packaging and slitting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A battery packaging slitting machine includes a machine base, a conveying mechanism mounted on the machine base, a partition plate mounted on the machine base and positioned above the conveyor belt of the conveying mechanism at its center, a frame mounted on the machine base and above the inlet end of the conveying mechanism, a slitting guide piece mounted on the bottom surface of the frame plate and located above the conveying mechanism, a slitting pressure head lifted and lowered above the slitting guide piece, a lifting drive mechanism mounted on the top surface of the frame plate for driving the lifting and lowering of the slitting pressure head, a thermoplastic coating mechanism mounted on the machine base and positioned above the center of the conveying mechanism, and an output guide rail positioned at the outlet end of the conveying mechanism. The inner cavity of the slitting guide piece is provided with two outlet channels, and the partition plate divides the conveyor belt of the conveying mechanism into two conveyor belts. The system includes two output channels, each corresponding to one of the two conveying channels. The frame's platform has a slitting hole with a slitting blade on its inner wall. The slitting blade divides the hole into two slitting chambers, each corresponding to one of the two output channels. A slitting groove is recessed in the center of the bottom surface of the slitting pressure head, allowing the slitting blade to insert into the slitting hole. A battery supply mechanism is installed on the top surface of the frame's platform to supply battery packs to the slitting hole. The output guide rail has two output channels, each corresponding to one of the two conveying channels. A conversion mechanism is located in the center of the output guide rail to change the battery packs in the two output channels from a horizontal to an vertical position.

[0008] Furthermore, the conversion mechanism includes two conversion wheels and a rotation drive module for driving the two conversion wheels to rotate, with the two conversion wheels respectively rotatably disposed in two output channels.

[0009] Furthermore, the peripheral sidewall of the transformation wheel is provided with multiple L-shaped transformation steps in a circular array; the long arm end of the L-shaped transformation step is provided with a guide arc surface.

[0010] Furthermore, the output guide rail includes an inclined guide rail section and a horizontal guide rail section. One end of the inclined guide rail section is used to connect with the discharge end of the conveying mechanism, and the other end of the inclined guide rail section is connected to one end of the horizontal guide rail section. The change wheel is located at the corner between the inclined guide rail section and the horizontal guide rail section.

[0011] Furthermore, a transition conveyor is connected to the end of the partition plate, and the discharge end of the conveying mechanism is connected to the inclined guide rail section via the transition conveyor.

[0012] Furthermore, the battery packaging slitting machine also includes a support platform set on one side of the machine base, the machine base table surface being higher than the support platform table surface, a horizontal guide rail section installed on the support platform table surface, a rotary drive module installed on the support platform, a change wheel rotatably connected to the support platform, and a through hole opened in the bottom wall of the output channel, through which the change wheel extends into the output channel.

[0013] Furthermore, the battery supply mechanism includes a U-shaped frame mounted on the top surface of the frame and surrounding the cutting hole, a stacking bin mounted above the open end of the U-shaped frame, a supply rail inclined downwards and connected to one side of the top port of the stacking bin, a push plate slidably connected to the top surface of the frame and movably disposed within the U-shaped frame, and a pusher driver mounted on the frame and used to drive the push plate to reciprocate. The push plate can open or close the bottom port of the stacking bin and is used to push the battery packs supplied by the stacking bin to the U-shaped frame to the top of the cutting hole.

[0014] Furthermore, a defective material drop hole is provided on the bottom wall of the middle section of the feeding rail.

[0015] Furthermore, a knife holder is installed on the top surface of the U-shaped frame, and a slicing knife is installed on the knife holder. The slicing knife extends into the U-shaped frame, and the cutting edge of the slicing knife and the cutting edge of the cutting knife are on the same vertical plane. The slicing knife is located between the stacking bin and the cutting hole.

[0016] Furthermore, the table surface of the machine is equipped with two guide plates, which are located on both sides of the conveyor belt of the conveying mechanism. A partition plate is located between the two guide plates. The partition plate, the guide plates, and the conveyor belt of the conveying mechanism form a conveying channel. The thermoplastic covering mechanism includes a cover that covers the two conveying channels and a hot air blower installed in the cover and communicating with the inner cavity of the cover.

[0017] The beneficial effects of this utility model are as follows: In practical applications, the battery supply mechanism supplies the battery pack to the area above the cutting hole, with the cutting pressure head positioned above the battery pack and the cutting blade located at the bottom of the cutting position of the battery pack. Simultaneously, the lifting drive mechanism drives the cutting pressure head downward, causing it to press down on the battery pack. Under the downward pressure applied by the cutting pressure head, the cutting blade cuts the cutting position of the battery pack until it inserts into the cutting groove of the cutting pressure head, thus completing the cutting of the battery pack into two battery packs. The cutting pressure head then presses the two battery packs into the two outlet channels of the cutting guide, and the battery packs travel along the outlet channels... The battery packs are moved to their corresponding conveying channels, where the conveying mechanism transports the battery packs lying flat. As the battery packs pass through the thermoplastic wrapping mechanism, the thermoplastic wrapping mechanism thermoplastically wraps the cut edges of the packaging film, ensuring the cut edges of the packaging film are covered on the battery, thus improving the quality of the battery packs. Next, the conveying mechanism transports the two thermoplastic-wrapped battery packs to the two output channels of the output guide rail. As the battery packs move along the output channels, a changing mechanism turns the lying battery packs into an upright position, allowing multiple battery packs to be transported vertically along the output channels, which is beneficial for subsequent vertical packaging. This invention not only enables the cutting and thermoplastic wrapping of battery packs but also transforms lying battery packs into upright ones, with the upright battery packs being transported in an arranged manner along the output channels.

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0026] like Figures 1 to 5As shown, this utility model provides a battery packaging slitting machine, which includes a machine base 1, a conveying mechanism 2 disposed on the machine base 1, a partition plate 3 mounted on the machine base 1 and disposed above the middle of the conveyor belt of the conveying mechanism 2, a frame 4 mounted on the machine base 1 and mounted above the feeding end of the conveying mechanism 2, a slitting guide 5 mounted on the bottom surface of the platform of the frame 4 and located above the conveying mechanism 2, a slitting pressure head 6 that is lifted and lowered above the slitting guide 5, a lifting drive mechanism 7 mounted on the top surface of the platform of the frame 4 and used to drive the slitting pressure head 6 to rise and fall, a thermoplastic wrapping mechanism 8 mounted on the machine base 1 and mounted above the middle of the conveying mechanism 2, and an output guide rail 9 disposed at the discharge end of the conveying mechanism 2. The inner cavity of the slitting guide 5 is provided with two discharge channels 10, and the partition plate 3 divides the conveyor belt of the conveying mechanism 2 into two conveyor belts. Channel 11, two output channels 10 are respectively set one-to-one with two conveying channels 11. The platform of the frame 4 has a slitting hole. The inner wall of the slitting hole is provided with a slitting blade 12. The slitting blade 12 divides the slitting hole into two slitting cavities 13. The two slitting cavities 13 are respectively set one-to-one with two output channels 10. The bottom surface of the slitting pressure head 6 is recessed with a slitting groove 14 for the slitting blade 12 to be inserted. The slitting pressure head 6 can extend into the slitting hole. The top surface of the platform of the frame 4 is equipped with a battery supply mechanism 15 for supplying battery packs to the slitting hole. The output guide rail 9 is provided with two output channels 16. The two output channels 16 are respectively set one-to-one with two conveying channels 11. The middle of the output guide rail 9 is provided with a conversion mechanism 17 for changing the battery packs in the two output channels 16 from a flat state to an upright state. This battery packaging slitting machine is used to cut battery packaging groups into battery packs, for example, to split a four-pack of batteries in half to cut them into two two-packs of batteries.

[0027] In practical applications, the battery supply mechanism 15 supplies the battery pack to the area above the slitting hole, with the slitting pressure head 6 positioned above the battery pack and the slitting blade 12 located at the bottom of the slitting position of the battery pack. Simultaneously, the lifting drive mechanism 7 drives the slitting pressure head 6 downwards, causing it to press down on the battery pack. Under the downward pressure applied by the slitting pressure head 6, the slitting blade 12 cuts the battery pack at the slitting position until it inserts into the slitting groove 14 of the slitting pressure head 6, thus completing the slitting of the battery pack into two battery packs. The slitting pressure head 6 then presses the two battery packs into the two outlet channels 10 of the slitting outlet 5, and the battery packs move along the outlet channels 10 to... Within the corresponding conveying channel 11, the conveying mechanism 2 transports the battery packs that are lying flat within the conveying channel 11. As the battery packs pass through the thermoplastic wrapping mechanism 8, the thermoplastic wrapping mechanism 8 thermoplastic wraps the cut edges of the packaging film of the slit battery packs, ensuring the cut edges of the packaging film are wrapped around the battery, thus improving the quality of the battery packs. Then, the conveying mechanism 2 transports the two thermoplastic-wrapped battery packs to the two output channels 16 of the output guide rail 9. As the battery packs move along the output channels 16, the changing mechanism 17 transforms the lying battery packs in the output channels 16 into an upright state, allowing multiple battery packs to be transported vertically along the output channels 16, which is beneficial for subsequent vertical packaging of the battery packs. This utility model not only enables the slitting and thermoplastic wrapping of battery packs but also transforms lying battery packs into upright ones, with the upright battery packs being transported in an arranged manner along the output channels 16.

[0028] In this embodiment, the conversion mechanism 17 includes two conversion wheels 18 and a rotation drive module 19 for driving the two conversion wheels 18 to rotate. The two conversion wheels 18 are respectively rotatably disposed in two output channels 16. The peripheral sidewalls of the conversion wheels 18 are arranged in a ring array with multiple L-shaped conversion steps 20. In practical applications, the rotation drive module 19 drives the two conversion wheels 18 to rotate synchronously. The flat battery packs move along the output channels 16, and the battery packs in the output channels 16 move one by one to different L-shaped conversion steps 20 of the conversion wheels 18. As the conversion wheels 18 rotate, the L-shaped conversion steps 20 will turn the flat battery packs into an upright state. Since the multiple upright battery packs are close together, the upright battery packs will move outward along the output channels 16 in an orderly manner to transport the upright battery packs.

[0029] In this embodiment, the long arm end of the L-shaped conversion step 20 is provided with a guide surface 21. When the horizontally lying battery pack enters the L-shaped conversion step 20, the guide surface 21 guides the battery pack, making it easier for the battery pack to enter the L-shaped conversion step 20; when the conversion wheel 18 changes the battery pack from a horizontal state to an vertical state and arranges it in the output channel 16, the guide surface 21 on the L-shaped conversion step 20 will abut against the vertically standing battery, thereby pushing the vertically arranged battery pack in the output channel 16 to move stably along the output channel 16.

[0030] In this embodiment, the output guide rail 9 includes an inclined guide rail section 22 and a horizontal guide rail section 23. One end of the inclined guide rail section 22 is used to connect with the discharge end of the conveying mechanism 2, and the other end of the inclined guide rail section 22 is connected to one end of the horizontal guide rail section 23. The change wheel 18 is located at the corner between the inclined guide rail section 22 and the horizontal guide rail section 23.

[0031] In practical applications, the conveying mechanism 2 transports the flat battery pack to the inclined guide rail section 22. Under the action of gravity, the battery pack slides down the inclined guide rail section 22 onto the L-shaped transformation step 20 of the transformation wheel 18. As the transformation wheel 18 drives the battery pack to rotate, the flat battery pack is transformed into an upright position on the horizontal guide rail section 23. The upright battery pack moves along the horizontal guide rail section 23.

[0032] In this embodiment, a transition conveyor 24 is connected to the end of the separator 3, and the discharge end of the conveying mechanism 2 is connected to the inclined guide rail section 22 via the transition conveyor 24. In practical applications, the battery pack output by the conveying mechanism 2 is conveyed to the inclined guide rail section 22 via the transition conveyor 24, so that the battery pack is stably conveyed between the conveying mechanism 2 and the inclined guide rail section 22.

[0033] In this embodiment, the battery packaging and slitting machine also includes a support platform 25 disposed on one side of the machine base 1. The table surface of the machine base 1 is higher than the table surface of the support platform 25. A horizontal guide rail section 23 is installed on the table surface of the support platform 25. A rotation drive module 19 is installed on the support platform 25. A conversion wheel 18 is rotatably connected to the support platform 25. A through hole 26 is provided on the bottom wall of the output channel 16, and the conversion wheel 18 extends into the output channel 16 through the through hole 26. This structural design makes the conversion wheel 18 and the output guide rail 9 compact, facilitating the conversion wheel 18 to turn the flat battery pack into an upright state.

[0034] Specifically, the lifting drive mechanism 7 can be a cylinder, and the rotation drive module 19 can be a transmission structure consisting of a motor, a synchronous belt, and a synchronous pulley.

[0035] In this embodiment, the battery supply mechanism 15 includes a U-shaped frame 27 mounted on the top surface of the platform of the frame 4 and surrounding the cutting hole, a stacking bin 28 mounted above the open end of the U-shaped frame 27, a supply rail 29 inclined from top to bottom and connected to one side of the top port of the stacking bin 28, a push plate 30 slidably connected to the top surface of the platform of the frame 4 and movably disposed within the U-shaped frame 27, and a pusher driver 31 mounted on the platform of the frame 4 and used to drive the push plate 30 to reciprocate. The push plate 30 can open or close the bottom port of the stacking bin 28 and is used to push the battery pack supplied by the stacking bin 28 to the top of the cutting hole. Specifically, the pusher driver 31 can be a cylinder.

[0036] In practical applications, battery packs slide tilted down along the feeding rail 29 into the stacking bin 28, allowing multiple battery packs to be stacked within the stacking bin 28. When the pusher driver 31 drives the pusher plate 30 to move outward, the pusher plate 30 opens the bottom port of the stacking bin 28, causing the bottommost battery pack in the stacking bin 28 to fall into the U-shaped frame 27. Then, the pusher driver 31 drives the pusher plate 30 to move inward along the U-shaped frame 27, pushing the battery packs in the U-shaped frame 27 towards the cutting hole. During the process of the pusher plate 30 pushing the battery packs towards the cutting hole, the pusher plate 30 closes the bottom port of the stacking bin 28, ensuring that the pusher plate 30 pushes only one battery pack at a time, thus improving the stability of the battery pack supply.

[0037] In this embodiment, a knife holder 33 is mounted on the top surface of the U-shaped frame 27, and a slicing blade 34 is mounted on the knife holder 33. The slicing blade 34 extends into the U-shaped frame 27, and the cutting edge of the slicing blade 34 is on the same vertical plane as the cutting edge of the slitting blade 12. The slicing blade 34 is located between the stacking bin 28 and the slitting hole. In practical applications, as the pusher plate 30 pushes the battery packaging assembly along the inner wall of the U-shaped frame 27 to the slitting hole, the slicing blade 34 will make a cut or make a preliminary cut at the slitting position of the packaging film of the battery packaging assembly, which is beneficial for the subsequent slitting blade 12 to smoothly and stably cut the battery packaging assembly.

[0038] In this embodiment, the platform of the machine 1 is equipped with two guide plates 35, which are located on both sides of the conveyor belt of the conveying mechanism 2. A partition plate 3 is located between the two guide plates 35, and the partition plate 3, the guide plates 35, and the conveyor belt of the conveying mechanism 2 form a conveying channel 11. When the conveying mechanism 2 conveys the battery pack in the conveying channel 11, the guide plates 35 and the partition plate 3 guide the movement of the battery pack, improving the stability of the battery pack movement.

[0039] In this embodiment, the thermoplastic coating mechanism 8 includes a cover 36 covering the two conveying channels 11 and a hot air blower 37 installed in the cover 36 and communicating with the inner cavity of the cover 36. When the battery pack passes through the thermoplastic coating mechanism 8, the hot air blower 37 blows hot air into the cover 36 and towards the battery pack, so that the packaging film of the battery pack is thermoplastically coated on the surface of the battery, improving the quality of the battery pack after cutting.

[0040] Specifically, a defective discharge hole 32 is provided on the bottom wall of the middle section of the feeding rail 29, and a defective output component is provided below the defective discharge hole 32. In practical applications, battery packs slide along the feeding rail 29. Since the number of battery cells in a defective battery pack is less than that in a normal battery pack, the defective battery pack will fall through the defective discharge hole 32 onto the defective output component. The defective battery pack will then slide down the defective output component to the collection position, while normal battery packs will pass through the defective discharge hole 32 and slide into the stacking bin 28. This structural design can screen out defective battery packs, ensuring that the machine can perform the cutting operation normally.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
