Description

Technical Field

[0001] This invention relates to the field of battery stacking technology, specifically to a battery stacking device for new energy vehicles. Background Technology

[0002] In the assembly and production of power battery packs for new energy vehicles, the battery stacking device is the core equipment for realizing the orderly arrangement of individual batteries, the precise fitting of steel ring protective sleeves, and the modular molding of battery packs.

[0003] Currently, in the steel ring assembly stage of traditional new energy vehicle battery stacking devices, manual placement or simple mechanical lifting methods are mostly used. The positioning and alignment of the steel rings rely entirely on the operator's visual judgment and manual adjustment, which has obvious precision defects and operational shortcomings. When placing the steel rings manually, it is difficult to ensure that the inner wall of the steel ring is completely coaxially aligned with the outer wall of the battery. This leads to jamming and stuttering during the subsequent upward lifting and assembly of the steel rings, which not only affects the assembly cycle but also causes steel ring deformation and scratches on the outer wall of the battery. Summary of the Invention

[0006] According to the above technical solution, a magnet is fixed above the base, and the steel ring is attached to the magnet. The magnet is used to make the steel ring move upward stably without deviating.

[0007] According to the above technical solution, the upper end of the long rod is hemispherical, and its arc surface is used to make the end of the abutment fit against the outer wall of the long rod. There are four abutments, so as to align the four sides of the steel ring.

[0008] According to the above technical solution, a cleaning device is provided on the inner side of the housing to prevent dust on the inner wall of the steel ring from obstructing the steel ring from being fitted onto the outer wall of the battery; a pressing device is provided at the bottom of the housing to make the steel ring fit more closely to the outer wall of the battery.

[0009] According to the above technical solution, the cleaning device includes: a long pipe that penetrates the bottom of the housing and is fixedly connected at the penetration point; a long pipe that penetrates the bottom of the base and is fixedly connected at the penetration point; a filter box fixed to the outer wall of the housing; the long pipe fixedly connected to the side wall of the filter box; a fan fixed to the outer wall of the housing and fixedly connected to the side wall of the filter box; a long rod that penetrates the outer wall of the long pipe and is slidably connected at the penetration point; and the fan being used to clean particulate matter from the inner wall of the steel ring.

[0010] According to the above technical solution, an air guide plate is fixed above the base, and the air guide plate is fixedly connected to the bottom of the placement platform. The air guide plate is used to improve the cleaning effect on the inner wall of the steel ring.

[0011] According to the above technical solution, the clamping device includes: a motor, the motor being fixed to the outer wall of the housing, a lead screw passing through the side wall of the housing and rotatably connected at the point of penetration, the end of the lead screw being fixedly connected to the output end of the motor, a sliding rod being fixed to the inner side wall of the housing, a connecting plate passing through the outer wall of the lead screw and threadedly connected at the point of penetration, the connecting plate passing through the sliding rod and slidably connected at the point of penetration, and a clamping block being fixed to the side of the connecting plate near the steel ring, the clamping block being used to make the steel ring fit more closely to the outer wall of the battery.

[0012] According to the above technical solution, a baffle is fixed to the outer wall of the slide rod, and a long spring is fixed to the side wall of the baffle. The long spring is fixedly connected to the side wall of the connecting plate, and the long spring is used to prevent the pressing block from damaging the battery.

[0013] This invention provides a battery stacking device for new energy vehicles. It has the following beneficial effects: 1. This invention, by setting up a U-shaped frame, a second electric push rod, a long rod, a limiting block, a stop rod, and a small spring, ensures that when the second electric push rod is controlled to move the long rod upward, the stop rod moves towards the steel ring, aligning each edge of the steel ring with the outer wall of the placement platform. This ensures that the inner wall of the steel ring is aligned with the outer wall of the battery, allowing the steel ring to move smoothly upward. This solves the problem of the steel ring getting stuck when manually placed and unable to align with the outer wall of the battery. Furthermore, by setting up a magnet, when the steel ring is placed above the magnet, the steel ring is pulled downward by the magnet. During the upward lifting process, the steel ring will not wobble or shift due to the magnetic force, thus solving the problem of the steel ring shifting and getting stuck during upward movement.

[0014] 2. This invention, by setting up a long pipe, a filter box, and a fan, allows air between the placement platform and the base to be drawn into the filter box through the long pipe after the fan is started. Particles on the inner wall of the steel ring are also drawn into the filter box through the long pipe, thereby achieving the effect of cleaning the particles on the inner wall of the steel ring. This solves the problem that the presence of particles on the inner wall of the steel ring increases the friction between the steel ring and the outer wall of the battery, causing the steel ring to move upward and get stuck.

[0015] 3. By setting up an air guide plate, this invention addresses the problem of insufficient suction on the inner wall of the steel ring due to the large space between the placement platform and the base. The air guide plate directs the airflow, allowing for better removal of particles from the inner wall of the steel ring, thus solving the problem of poor cleaning effect on the inner wall of the steel ring caused by weak suction.

[0016] 4. This invention, by setting up a motor, lead screw, slide bar, connecting plate, and clamping block, allows the motor to be started after the steel ring is in contact with the outer wall of the battery. After the lead screw rotates, the connecting plate drives the clamping block to move towards the steel ring, thereby pressing the corner of the steel ring. This causes the steel ring to deform, achieving a better fit between the steel ring and the outer wall of the battery, solving the problem of the battery becoming loose after the steel ring is stretched over a long period of use.

[0017] 5. This invention, by setting up a baffle and a long spring, compresses the long spring during the movement of the connecting plate, making the connecting plate more stable during movement. When the connecting plate drives the clamping block to contact the steel ring, the elastic force of the large spring increases. When the large spring is compressed to its limit, the clamping block can no longer move, thus preventing the clamping block from damaging the battery. This solves the problem of excessive pressure from the clamping block damaging the battery due to inaccurate manual control of the clamping block's movement. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6One embodiment of the present invention is: a new energy vehicle battery stacking device, comprising: a base 2 fixed to the bottom of the inner side of a housing 1, a placement platform 3 fixed above the base 2, a fixed plate 4 fixed above the base 2, and a steel ring 6 disposed above the base 2. A pressure device 5 includes: a third electric push rod, the third electric push rod being fixed to the inner wall of the housing 1, a movable plate fixed to the extended end of the third electric push rod, the movable plate being used to press and stack the batteries; a fixing frame 7 fixed to the bottom of the housing 1, a first electric push rod 8 fixed to the bottom of the fixing frame 7, a frame 9 fixed to the extended end of the first electric push rod 8, a vertical rod 10 fixed above the frame 9, the vertical rod 10 penetrating the bottom of the housing 1 and slidably connected at the penetration point, a push plate 11 fixed to the upper end of the vertical rod 10, the push plate 11 being used to fit the steel ring 6 onto the outer wall of the battery; and a centering device 18 including: a third electric push rod 8. Four electric push rods are fixed to the inner wall of the housing 1. The extended end of the fourth electric push rod is fixed with a centering plate, which is used to align the batteries. A U-shaped frame 12 is fixed to the bottom of the housing 1. A second electric push rod 13 is fixed to the bottom of the U-shaped frame 12. A long rod 14 is fixed to the extended end of the second electric push rod 13. A limit block 15 is fixed to the bottom of the placement platform 3. The limit block 15 is fixedly connected to the top of the base 2. A stop rod 16 passes through the limit block 15 and is slidably connected at the passage. A small spring 17 is fixed to the side of the limit block 15 near the long rod 14. The small spring 17 is fixedly connected to the outer wall of the stop rod 16. The stop rod 16 is used to align the inner wall of the steel ring 6 with the outer wall of the battery. A magnet 19 is fixed to the top of the base 2. The steel ring 6 is attached to the magnet 19. The magnet 19 is used to ensure that the steel ring 6 moves upward stably without deviating.

[0022] The upper end of the long rod 14 is hemispherical, and its arc surface is used to make the end of the abutment rod 16 fit against the outer wall of the long rod 14. There are four abutment rods 16, so as to align the four sides of the steel ring 6. By setting up the U-shaped frame 12, the second electric push rod 13, the long rod 14, the limiting block 15, the abutment rod 16 and the small spring 17, when the second electric push rod 13 is controlled to make the long rod 14 move upward, the abutment rod 16 moves towards the steel ring 6, so that each side of the steel ring 6 is aligned with the outer wall of the placement platform 3, ensuring that the inner wall of the steel ring 6 is aligned with the outer wall of the battery, so that the steel ring 6 can move upward smoothly, solving the problem of the steel ring 6 getting stuck when manually placed and unable to be aligned with the outer wall of the battery. Furthermore, by setting up magnet 19, after placing steel ring 6 above magnet 19, steel ring 6 is pulled downward by magnet 19. During the upward lifting process of steel ring 6, affected by magnetic force, steel ring 6 will not sway or deviate, thus solving the problem of steel ring 6 deviating during the upward movement and causing steel ring 6 to move and get stuck.

[0023] In this embodiment, after the steel ring 6 is placed on the placement platform 3, the battery pack is placed on top of the placement platform 3, causing the second electric push rod 13 to extend and the long rod 14 to move upward. Initially, the end of the abutment rod 16 is in contact with the arc surface of the upper end of the long rod 14. When the long rod 14 moves upward, it forces the abutment rod 16 to move, accompanied by the compression of the small spring 17. After the abutment rod 16 extends outward, it adjusts the steel ring 6 to a position where the inner wall is in contact with the outer wall of the battery. The steel ring 6 is placed on the magnet 19 of the base 2. After ascending, the steel ring 6 is stabilized by the downward magnetic force, becoming even more stable during the subsequent ascent. Then, the fourth electric push rod is activated, causing the centering plates on both sides to center the battery towards the middle. Next, the third electric push rod is activated, causing the moving plate to push the battery towards the fixed plate 4, making the batteries stack tightly. Then, the first electric push rod 8 is activated, causing the frame 9 to move the vertical rod 10 and the push plate 11 upward. The push plate 11 pushes the steel ring 6 upward, so that the steel ring 6 fits onto the outer wall of the battery, completing the battery stacking.

[0024] Please see Figures 1-6 Based on the above embodiments, in another embodiment of the present invention, a cleaning device is provided on the inner side of the housing 1. The cleaning device is used to prevent dust on the inner wall of the steel ring 6 from obstructing the steel ring 6 from being fitted onto the outer wall of the battery.

[0025] The cleaning device includes: a long pipe 201, a filter box 202, a fan 203, and a guide plate 204; the long pipe 201 passes through the bottom of the housing 1 and is fixedly connected at the penetration point; the long pipe 201 passes through the bottom of the base 2 and is fixedly connected at the penetration point; the filter box 202 is fixed to the outer wall of the housing 1; the long pipe 201 is fixedly connected to the side wall of the filter box 202; the fan 203 is fixed to the outer wall of the housing 1 and is fixedly connected to the side wall of the filter box 202; the long rod 14 passes through the outer wall of the long pipe 201 and is slidably connected at the penetration point; the fan 203 is used to clean the particulate matter on the inner wall of the steel ring 6.

[0026] An air guide plate 204 is fixed above the base 2 and is fixedly connected to the bottom of the placement platform 3. The air guide plate 204 is used to improve the cleaning effect on the inner wall of the steel ring 6. By setting up a long pipe 201, a filter box 202 and a fan 203, after the fan 203 is turned on, the air between the placement platform 3 and the base 2 is drawn into the filter box 202 through the long pipe 201. The particles on the inner wall of the steel ring 6 are also drawn into the long pipe 201 and into the filter box 202, thereby achieving the effect of cleaning the particles on the inner wall of the steel ring 6. This solves the problem that the presence of particles on the inner wall of the steel ring 6 increases the friction between the steel ring 6 and the outer wall of the battery, causing the steel ring 6 to move upward and get stuck.

[0027] By setting the air guide plate 204, the space between the placement platform 3 and the base 2 is too large, resulting in weak suction on the inner wall of the steel ring 6. The setting of the air guide plate 204 guides the air, which can better suck away the particles on the inner wall of the steel ring 6, thus solving the problem of poor cleaning effect of particles on the inner wall of the steel ring 6 caused by weak suction.

[0028] A clamping device is installed at the bottom of the housing 1. The clamping device is used to make the steel ring 6 fit more closely to the outer wall of the battery. The clamping device includes: a motor 211, a lead screw 212, a slide rod 213, a connecting plate 214, a clamping block 215, a baffle 216, and a long spring 217. The motor 211 is fixed to the outer wall of the housing 1. The lead screw 212 passes through the side wall of the housing 1 and is rotatably connected at the point of penetration. The end of the lead screw 212 is fixedly connected to the output end of the motor 211. A slide rod 213 is fixed to the inner side wall of the housing 1. A connecting plate 214 passes through the outer wall of the 2, and is threaded at the point of penetration. The connecting plate 214 passes through the slide rod 213, and is slidably connected at the point of penetration. A clamping block 215 is fixed on the side of the connecting plate 214 near the steel ring 6. The clamping block 215 is used to make the steel ring 6 fit more closely to the outer wall of the battery. A baffle 216 is fixed on the outer wall of the slide rod 213. A long spring 217 is fixed on the side wall of the baffle 216. The long spring 217 is fixedly connected to the side wall of the connecting plate 214. The long spring 217 is used to prevent the clamping block 215 from damaging the battery.

[0029] By setting up a motor 211, a lead screw 212, a slide bar 213, a connecting plate 214, and a clamping block 215, after the steel ring 6 is attached to the outer wall of the battery, the motor 211 is started. After the lead screw 212 rotates, the connecting plate 214 drives the clamping block 215 to move towards the steel ring 6, thereby pressing the corner of the steel ring 6 with the clamping block 215. This causes the steel ring 6 to deform, achieving a better fit between the steel ring 6 and the outer wall of the battery, thus solving the problem of the battery becoming loose after the steel ring 6 is stretched over a long period of use.

[0030] By setting baffle 216 and long spring 217, the long spring 217 is compressed during the movement of connecting plate 214, making connecting plate 214 more stable during movement. When connecting plate 214 drives clamping block 215 to contact steel ring 6, the elasticity of long spring 217 increases. When long spring 217 is compressed to the extreme, clamping block 215 can no longer move, thus preventing clamping block 215 from damaging the battery and solving the problem of excessive pressure from clamping block 215 damaging the battery due to inaccurate manual control of clamping block 215 movement.

[0031] In this embodiment, after the steel ring 6 is placed, the fan 203 is started. After the fan 203 is started, the fan 203 draws the air out of the long pipe 201, thereby drawing the air between the base 2 and the placement platform 3 into the long pipe 201. This draws the particles on the inner wall of the steel ring 6 into the long pipe 201, and then into the filter box 202 for storage. The air guide plate 204 guides the airflow between the placement platform 3 and the base 2, thereby increasing the suction force on the particles on the inner wall of the steel ring 6 and better cleaning the particles inside the steel ring 6.

[0032] After the steel ring 6 is fitted onto the outer wall of the battery, the motor 211 is started. After the motor 211 rotates, the connecting plates 214 on both sides move towards the steel ring 6, thereby driving the clamping block 215 to press the steel ring 6 tightly, so that the steel ring 6 fits more closely to the outer wall of the battery. During the movement of the connecting plate 214, the long spring 217 is compressed. When the connecting plate 214 and the clamping block 215 move to the point that the long spring 217 is compressed to the extreme, the connecting plate 214 moves in the opposite direction to prevent the clamping block 215 from damaging the battery.

[0033] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
