Description

Technical Field

[0001] This utility model relates to the field of electric vehicle assembly technology, and specifically discloses a feeding mechanism for electric vehicle assembly equipment. Background Technology

[0002] Electric vehicles, as a green mode of transportation powered by electricity, rely on efficient and stable battery systems for their core performance. Battery cells, as the basic energy units of a battery, are typically stacked and assembled to form battery modules with specific voltages and capacities to meet the power demands of electric vehicles. Battery cells (such as rectangular lithium-ion cells) have precise dimensional tolerances and electrode placement requirements; their assembly accuracy directly affects the safety, energy density, and cycle life of the battery module. Therefore, automated feeding and precise stacking of battery cells are critical process steps in electric vehicle battery production.

[0003] Currently, in traditional battery cell assembly processes, the stacking of cells largely relies on manual operation, which has significant drawbacks. Firstly, manual stacking makes it difficult to ensure the parallelism and center alignment of the cells in the vertical direction, easily leading to electrode misalignment and subsequent safety hazards such as increased contact resistance and localized overheating. Secondly, after stacking, fiber tape is typically used to secure the cell assembly. However, when manually applying pressure for fixation, the cells are prone to lateral displacement or tilting during the fixing process, resulting in dimensional deviations in the fixed cell module and affecting its subsequent compatibility with the battery casing and electrode connectors. Therefore, a feeding mechanism for electric vehicle assembly equipment is needed to solve these problems. Utility Model Content

[0005] This utility model is implemented as follows: a feeding mechanism for electric vehicle assembly equipment includes a base plate and multiple battery cells. A placement platform is fixedly connected to the upper end of the base plate, and an L-shaped positioning plate is fixedly connected to the upper end of the placement platform. A support plate located to the left of the placement platform is provided above the base plate, and support bars are provided on both the left and right sides of the support plate. An automatic feeding mechanism and a pressure application mechanism are provided above the base plate.

[0006] The automatic feeding mechanism includes a supporting steel column fixedly connected to the upper end of the base plate. A circular shell is fixedly connected to the upper end of the supporting steel column. A turntable is rotatably connected to the upper end of the circular shell. A stepper motor with its output end fixedly connected to the turntable is installed inside the circular shell. A rotating plate is fixedly connected to the upper end of the turntable. A first electric push rod is installed on the upper end of the rotating plate. A housing is provided below the rotating plate. A first pressure sensor is fixedly connected between the output end of the first electric push rod, the rotating plate, and the housing. A vacuum suction cup is connected to the lower end of the housing. A vacuum pump with its air inlet end connected to the interior of the housing is installed on the outer wall of the housing.

[0007] The pressure application mechanism includes a second electric push rod installed on the upper part of the rotating plate, a pressure plate is provided below the rotating plate, and a second pressure sensor is fixedly connected between the output end of the second electric push rod and the pressure plate.

[0008] A controller and an operation panel are located above the rotating plate.

[0009] As a preferred material feeding mechanism for an electric vehicle assembly equipment according to this utility model, both the front and rear ends of the box are fixedly connected to connecting plates, and the upper ends of the two connecting plates are fixedly connected to sliding rods that penetrate the rotating plate and are slidably connected to the rotating plate.

[0010] As a preferred material feeding mechanism of an electric vehicle assembly equipment according to this utility model, the upper end of the pressure plate is fixedly connected to two guide rods that penetrate the rotating plate and are slidably connected to the rotating plate.

[0011] As a preferred embodiment of the feeding mechanism of the electric vehicle assembly equipment of this utility model, two support rods are fixedly connected between the support plate and the base plate, and a fixing strip is fixedly connected to the lower end of each of the two support rods, and both fixing strips are fixedly connected to the base plate.

[0012] As a preferred material feeding mechanism for an electric vehicle assembly equipment according to this utility model, a gap is provided between the two support bars and the support plate.

[0013] As a preferred material feeding mechanism of the electric vehicle assembly equipment of this utility model, the upper end of the rotating plate is fixedly connected to a vertical plate, and the controller and operation panel are installed at the front end of the vertical plate.

[0014] As a preferred material feeding mechanism of an electric vehicle assembly equipment according to this utility model, the lower end of the pressure plate is equipped with a rubber pad.

[0015] The beneficial effects of this utility model are:

[0016] 1. The operator places the battery cells to be assembled on the placement table, ensuring precise positioning against the inner wall of the L-shaped positioning plate. In the initial state, the controller activates the first electric push rod to lower the vacuum suction cup. Once the first pressure sensor detects sufficient contact pressure, the vacuum pump is activated to suction the topmost battery cell. After the vacuum suction cup moves upward, the cell is transferred to the top of the support plate. The first electric push rod then lowers the cell again. Once the first pressure sensor detects sufficient pressure, the suction force on the cell is released, and the vacuum suction cup returns to its original position. Repeating this suction, transfer, and placement process allows a specified number of battery cells to be stacked layer by layer on the support plate and support bars. This effectively improves the vertical parallelism and center alignment accuracy of the stacked battery cells, preventing electrode misalignment and enhancing safety.

[0017] 2. After all battery cells are stacked, the controller controls the second electric push rod to move the pressure plate downward. When the second pressure sensor detects that the applied pressure has reached the target, the pressure plate continuously applies stable pressure to the battery cells. At this time, the operator can wrap fiber tape around the stacked battery cells in the gap between the support plate and the support bar. The pressure plate continuously applies stable pressure to prevent the battery cells from shifting laterally or tilting during the wrapping process, thus avoiding dimensional deviations in the cell module.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0026] Please see Figure 1-5 A feeding mechanism for an electric vehicle assembly equipment includes a base plate 1 and multiple battery cells 4. A placement platform 2 is fixedly connected to the upper end of the base plate 1, and an L-shaped positioning plate 3 is fixedly connected to the upper end of the placement platform 2. A support plate 5 located to the left of the placement platform 2 is provided above the base plate 1, and support bars 6 are provided on both the left and right sides of the support plate 5. An automatic feeding mechanism and a pressure application mechanism are provided above the base plate 1.

[0027] The automatic feeding mechanism includes a support steel column 9 fixedly connected to the upper end of the base plate 1. A circular shell 10 is fixedly connected to the upper end of the support steel column 9. A turntable 11 is rotatably connected to the upper end of the circular shell 10. A stepper motor 26 with its output end fixedly connected to the turntable 11 is installed inside the circular shell 10. A rotating plate 12 is fixedly connected to the upper end of the turntable 11. A first electric push rod 13 is installed at the upper end of the rotating plate 12. A housing 14 is provided below the rotating plate 12. A first pressure sensor 17 is fixedly connected between the output end of the first electric push rod 13, the rotating plate 12, and the housing 14. A vacuum suction cup 15 is connected to the lower end of the housing 14. A vacuum pump 16 with its air inlet end connected to the interior of the housing 14 is installed on the outer wall of the housing 14.

[0028] The pressure application mechanism includes a second electric push rod 19 installed on the upper end of the rotating plate 12, a pressure plate 18 is provided below the rotating plate 12, and a second pressure sensor 20 is fixedly connected between the output end of the second electric push rod 19 through the rotating plate 12 and the pressure plate 18.

[0029] A controller 22 and an operation panel 21 are provided on the top of the turntable 12.

[0030] In this embodiment: First, the operator places multiple battery cells 4 to be assembled on the upper end of the placement platform 2, so that the multiple battery cells 4 are in contact with the rear side and the right side of the inner wall of the L-shaped positioning plate 3, thereby accurately positioning the placement position of the battery cells 4. Then, the operator inputs working parameters and process instructions through the operation panel 21. The operation panel 21 transmits the signals to the controller 22, which pre-stores and parses the control logic to provide instruction basis for the subsequent automation process.

[0031] Subsequently, the stepper motor 26 inside the circular shell 10 is driven by the controller 22 to rotate the turntable 11 and the upper rotating plate 12 to the initial working position. At this time, the vacuum suction cup 15 is aligned with the battery cell 4 above the placement platform 2, and the vacuum suction cup 15 is located above the L-shaped positioning plate 3. Then, the controller 22 controls the first electric push rod 13 at the upper end of the rotating plate 12 to extend downward. Its output end pushes the box 14 and the lower vacuum suction cup 15 to move vertically downward through the first pressure sensor 17. When the vacuum suction cup 15 contacts the uppermost battery cell 4, the first pressure sensor 17 monitors the contact pressure in real time. When the pressure reaches the preset threshold, the first electric push rod 13 stops moving, and the controller 22 simultaneously starts the vacuum pump 16. The vacuum pump 16 forms a negative pressure adsorption with the vacuum suction cup 15 through the cavity inside the box 14, and stably sucks up the uppermost battery cell 4.

[0032] After vacuum adsorption is completed, the first electric push rod 13 drives the vacuum suction cup 15 to move upward, so that the battery cell 4 is higher than the L-shaped positioning plate 3. At this time, the controller 22 controls the stepper motor 26 to drive the turntable 11 and the rotating plate 12 to rotate synchronously by 180 degrees, so that the battery cell 4 rotates with the rotating plate 12 to the top of the support plate 5. Then the controller 22 controls the first electric push rod 13 to move downward again, so that the battery cell 4 descends to the top of the support plate 5 and the two support bars 6. The support plate 5 and the two support bars 6 support the battery cell 4. At this time, the first pressure sensor 17 monitors the contact pressure between the battery cell 4 and the support plate 5 and the support bars 6. When the pressure reaches the standard, the controller 22 controls the vacuum pump 16 and the first electric push rod 13 to stop working, releasing the adsorption of the battery cell 4 by the vacuum suction cup 15. Then the first electric push rod 13 moves upward, and the rotating plate 12 rotates in the opposite direction by 180 degrees to return to the initial position, completing the transfer of the single-layer battery cell 4.

[0033] By repeating the above adsorption, transfer and placement process, a specified number of battery cells 4 on the placement platform 2 can be stacked layer by layer on the upper end of the support plate 5 and support bar 6, thereby completing the positioning and placement of the battery cells 4 on the upper end of the support plate 5 and support bar 6. This can effectively improve the vertical parallelism and center alignment accuracy of the battery cells 4 during stacking, thereby avoiding electrode misalignment and improving safety.

[0034] After all battery cells 4 have been placed, the vacuum suction cup 15 returns to its initial position. At this time, the pressure plate 18 is directly above the support plate 5. The controller 22 controls the second electric push rod 19 to extend downwards. Its output end pushes the pressure plate 18 downwards through the second pressure sensor 20. After the rubber pad at the lower end of the pressure plate 18 contacts the top surface of the battery cell 4, the second pressure sensor 20 monitors the applied pressure in real time. When the pressure reaches the preset value, the second electric push rod 19 stops moving and continues to apply pressure to the battery cell 4. At this time, the battery cell 4 is just pressed tightly. The operator can wrap the stacked battery cells 4 with fiber tape in the gap between the support plate 5 and the support bar 6. At this time, the pressure plate 18 continuously applies stable pressure to prevent the battery cells 4 from shifting laterally or tilting during the wrapping process, thus avoiding dimensional deviations in the battery cell module.

[0035] As a technical optimization of this utility model, the front and rear ends of the box 14 are fixedly connected with connecting plates 24, and the upper ends of the two connecting plates 24 are fixedly connected with sliding rods 23 that pass through the rotating plate 12 and are slidably connected to the rotating plate 12.

[0036] In this embodiment: by setting two connecting plates 24, the slide rod 23 is fixed. By setting two slide rods 23, a guiding effect is provided when the box 14 moves, thereby improving the accuracy and stability of the movement of the box 14.

[0037] As a technical optimization of this utility model, the upper end of the pressure plate 18 is fixedly connected to two guide rods 25 that penetrate the rotating plate 12 and are slidably connected to the rotating plate 12.

[0038] In this embodiment, by setting two guide rods 25, a guiding effect is provided when the pressure plate 18 moves, thereby improving the accuracy and stability of the movement of the pressure plate 18.

[0039] As a technical optimization of this utility model, two support rods 7 are fixedly connected between the support plate 5 and the base plate 1, and the lower ends of the two support bars 6 are fixedly connected with fixing bars 8, and the two fixing bars 8 are fixedly connected to the base plate 1.

[0040] In this embodiment, by setting two support rods 7 and two support bars 6, the support plate 5 and the two support bars 6 can be supported and fixed.

[0041] As a technical optimization of this utility model, a gap is provided between the two support bars 6 and the support plate 5.

[0042] In this embodiment: Since there is a gap between the two support bars 6 and the support plate 5, the operator can wrap the stacked battery cells 4 with fiber tape through the gap.

[0043] As a technical optimization of this utility model, the upper end of the rotating plate 12 is fixedly connected to the upright plate, and the controller 22 and the operation panel 21 are installed at the front end of the upright plate.

[0044] In this embodiment: by setting up a support plate, it is convenient to install and fix the controller 22 and the operation panel 21.

[0045] As a technical optimization of this utility model, the lower end of the pressure plate 18 is equipped with a rubber pad.

[0046] In this embodiment, the battery cell 4 is protected by setting a rubber pad.

[0047] The working principle and usage process of this utility model are as follows: First, the operator places multiple battery cells 4 to be assembled on the upper end of the placement platform 2, so that the multiple battery cells 4 are in contact with the rear side and the right side of the inner wall of the L-shaped positioning plate 3, thereby accurately positioning the placement position of the battery cells 4. Then, the operator inputs working parameters and process instructions through the operation panel 21. The operation panel 21 transmits the signals to the controller 22, which pre-stores and parses the control logic to provide instruction basis for the subsequent automation process.

[0048] Subsequently, the stepper motor 26 inside the circular shell 10 is driven by the controller 22 to rotate the turntable 11 and the upper rotating plate 12 to the initial working position. At this time, the vacuum suction cup 15 is aligned with the battery cell 4 above the placement platform 2, and the vacuum suction cup 15 is located above the L-shaped positioning plate 3. Then, the controller 22 controls the first electric push rod 13 at the upper end of the rotating plate 12 to extend downward. Its output end pushes the box 14 and the lower vacuum suction cup 15 to move vertically downward through the first pressure sensor 17. When the vacuum suction cup 15 contacts the uppermost battery cell 4, the first pressure sensor 17 monitors the contact pressure in real time. When the pressure reaches the preset threshold, the first electric push rod 13 stops moving, and the controller 22 simultaneously starts the vacuum pump 16. The vacuum pump 16 forms a negative pressure adsorption with the vacuum suction cup 15 through the cavity inside the box 14, and stably sucks up the uppermost battery cell 4.

[0049] After vacuum adsorption is completed, the first electric push rod 13 drives the vacuum suction cup 15 to move upward, so that the battery cell 4 is higher than the L-shaped positioning plate 3. At this time, the controller 22 controls the stepper motor 26 to drive the turntable 11 and the rotating plate 12 to rotate synchronously by 180 degrees, so that the battery cell 4 rotates with the rotating plate 12 to the top of the support plate 5. Then the controller 22 controls the first electric push rod 13 to move downward again, so that the battery cell 4 descends to the top of the support plate 5 and the two support bars 6. The support plate 5 and the two support bars 6 support the battery cell 4. At this time, the first pressure sensor 17 monitors the contact pressure between the battery cell 4 and the support plate 5 and the support bars 6. When the pressure reaches the standard, the controller 22 controls the vacuum pump 16 and the first electric push rod 13 to stop working, releasing the adsorption of the battery cell 4 by the vacuum suction cup 15. Then the first electric push rod 13 moves upward, and the rotating plate 12 rotates in the opposite direction by 180 degrees to return to the initial position, completing the transfer of the single-layer battery cell 4.

[0050] By repeating the above adsorption, transfer and placement process, a specified number of battery cells 4 on the placement platform 2 can be stacked layer by layer on the upper end of the support plate 5 and support bar 6, thereby completing the positioning and placement of the battery cells 4 on the upper end of the support plate 5 and support bar 6. This can effectively improve the vertical parallelism and center alignment accuracy of the battery cells 4 during stacking, thereby avoiding electrode misalignment and improving safety.

[0051] After all battery cells 4 have been placed, the vacuum suction cup 15 returns to its initial position. At this time, the pressure plate 18 is directly above the support plate 5. The controller 22 controls the second electric push rod 19 to extend downwards. Its output end pushes the pressure plate 18 downwards through the second pressure sensor 20. After the rubber pad at the lower end of the pressure plate 18 contacts the top surface of the battery cell 4, the second pressure sensor 20 monitors the applied pressure in real time. When the pressure reaches the preset value, the second electric push rod 19 stops moving and continues to apply pressure to the battery cell 4. At this time, the battery cell 4 is just pressed tightly. Since there is a gap between the support plate 5 and the support bar 6, the operator can wrap the stacked battery cells 4 with fiber tape through this gap. At this time, the pressure plate 18 continuously applies stable pressure to prevent the battery cells 4 from shifting laterally or tilting during the wrapping process, thus avoiding dimensional deviations in the battery cell module.
