Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery manufacturing, specifically to a tooling for applying adhesive to the lugs of battery electrode groups. Background Technology

[0002] Lead-acid batteries, as the most mature and reliable battery type, boast advantages such as low self-discharge, minimal water loss, high current discharge performance, and long deep cycle life. However, with stricter emission standards for gasoline vehicles, and the need to increase front-mounted space for intelligent design and reduced fuel consumption, the original front-mounted fuel tank is being redesigned as a larger tank to increase capacity, reduce refueling frequency during long-distance transport, shorten operating time, and increase driving range. This reduces the available front-mounted space for batteries in gasoline vehicles, inevitably leading to a shift from the original front-mounted battery layout to a rear-mounted design.

[0003] With batteries installed at the rear of a vehicle, the rear-mounted batteries experience greater vibrations than the front-mounted batteries during operation. This is especially true for large heavy-duty trucks or semi-trailers, where the rear-end vibration conditions are even more severe, placing higher demands on the vibration resistance of rear-mounted batteries. Furthermore, traditional lead-acid battery production lines' automated glue-applying equipment can only apply glue to the top and bottom of the electrode group. This method cannot effectively secure the electrode group, and under higher vibration conditions, the plate lugs may break, leading to premature battery failure. To meet these new market demands and improve the vibration resistance of lead-acid batteries, heating and melting glue in the gaps between the electrode lugs has become an effective solution.

[0004] Utility model patent CN 216936850 U discloses a tooling for applying glue to the tabs of lead-acid battery terminals. It consists of a frame, a linear motion module, a glue gun, and a battery positioning platform. The linear motion module is mounted on the upper part of the frame. The battery positioning platform is hinged to the lower part of the frame via a battery angle adjustment mechanism. The glue gun is mounted and fixed on the linear motion module via a glue gun angle adjustment mechanism. In use, the battery is manually or robotically moved to the battery positioning platform. Then, the positioning platform angle adjustment lever is manually operated to rotate the platform to the required angle according to the battery length. Glue is then applied, and the battery is allowed to cool. Afterward, the battery is manually or robotically flipped 180° for glue application on the other side. During the cooling and flipping processes, the glue gun is in a waiting state, severely impacting production efficiency. The battery angle adjustment mechanism has a complex structure and requires manual operation to adjust the extension and retraction of the battery positioning platform to the required angle. Furthermore, if manual handling is used to move batteries from the main production line, the heavy weight of the batteries makes handling difficult and inefficient. Connecting the existing equipment to the main assembly line will cause material accumulation on the main line, and subsequent assembly stations will be in a waiting state for a long time, affecting the overall assembly efficiency. On the other hand, if a robot is used to move batteries, and speed is increased by expanding the number of stations, one robot cannot meet the requirements of multiple stations, while multiple robots require a lot of space and the cost of robots is relatively high. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tooling for gluing battery electrode lugs, which significantly improves the production efficiency of lead-acid batteries, has a wide range of applications, and is low in cost.

[0006] A tooling for applying adhesive to battery electrode lugs is set on one side of the main assembly conveyor line of the battery, including a bullseye platform and an electrode lug dispensing machine.

[0007] The bullseye platform is evenly distributed with several bullseye bearings, and there are limit stops on both sides of the bullseye platform. The limit stops are perpendicular to the movement direction of the main assembly conveyor line.

[0008] The plate-ear dispensing machine is arranged on one side of the bullseye platform. The plate-ear dispensing machine includes a frame, a roller conveyor line and a glue gun.

[0009] The roller conveyor lines consist of two lines, which are hinged side by side within the frame. Each roller conveyor line is equipped with a flipping drive device, which is used to drive the corresponding roller conveyor line to flip.

[0010] The glue gun is fixed to the moving platform of the linear module via a glue gun angle adjustment device, and the linear module spans two roller conveyor lines.

[0011] The transport direction of the roller conveyor is perpendicular to the movement direction of the main assembly conveyor.

[0012] The roller conveyor line is equipped with a front baffle, a fixed side baffle, and a flat push plate for positioning the battery. The front baffle is located at the lower end of the roller conveyor line after it is flipped to prevent the battery from slipping off after flipping. Rubber pads are affixed to the front baffle, the fixed side baffle, and the flat push plate to prevent the battery from being scratched.

[0013] The fixed side baffle is set opposite to the flat push plate to restrict the position of the battery from the left and right sides. The flat push plate is mounted on the telescopic rod of the flat push cylinder, and the fixed side baffle is located on the side closer to the two adjacent roller conveyor lines.

[0014] The front baffle is mounted on the top of the lifting cylinder. When the lifting cylinder is raised to the position, the front baffle protrudes from the upper plane of the roller conveyor. When the lifting cylinder is lowered to the position, the front baffle is lower than the upper plane of the roller conveyor.

[0015] The upper surface of the rollers in the roller conveyor line is flush with the upper surface of the bullseye bearing on the bullseye platform.

[0016] The two limit stops are provided with bullseye bearings arranged side by side on opposite sides.

[0017] The glue gun angle adjustment device includes a glue gun fixing rod and an adjustment frame. The glue gun fixing rod is connected to the adjustment frame with adjustable tilt angle and height. The upper end of the adjustment frame is fixed to the moving platform of the linear module.

[0018] The adjustment frame includes an adjustment plate, one end of which is fixed with a long vertical rod, and the other end has a short vertical rod whose horizontal position is adjustable. The glue gun fixing rod is installed at an angle between the long vertical rod and the short vertical rod.

[0019] The tilt angle of the glue gun fixing rod is the same as the tilt angle after the roller conveyor line is flipped.

[0020] The glue gun consists of multiple glue guns arranged according to the distribution requirements of the solar panel ears, and is mounted and fixed on the glue gun fixing rod of the glue gun angle adjustment device.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] 1. This utility model achieves hot melt adhesive filling of the gap between the plate ears of the battery electrode group by arranging the bullseye platform and the plate ear dispensing machine at the side of the production line. It effectively solves the problems of complex production process, large workload and long time consumption under the traditional operation method, and significantly improves the production efficiency of lead-acid batteries. Moreover, it occupies less space than a robot, has a wider range of applications, and is lower in cost.

[0023] 2. The roller conveyor system designed in this utility model can switch between two working positions: horizontal and at a 60° angle to the ground. With the help of the limiting mechanism, it effectively solves the problem of insufficient adaptability of battery clamps and improves the flexibility and adaptability of the production line. The glue gun of the plate ear dispensing unit applies glue to two stations. When one station is cooling, the other station is in the glue application state, which improves the production rhythm.

[0024] 3. The glue gun of this utility model, with its glue gun angle adjustment device, can be flexibly adjusted according to different battery models, meeting the production needs of batteries of different sizes and quantities.

[0025] 4. This utility model adopts a modular design in the main frame and the dispensing components, which facilitates maintenance and replacement, reduces equipment maintenance costs, and extends service life. Attached Figure Description

[0032] like Figure 1As shown, this utility model provides a tooling for gluing lead-acid battery electrode group plates, including a bullseye platform 3 and a plate glue dispensing machine 4. The bullseye platform 3 is located on one side of the main assembly conveyor line 2 of the battery 1, and the plate glue dispensing machine 4 is located on the other side of the bullseye platform 3 and opposite to the main assembly conveyor line 2. Limiting rods 12 for preventing the battery from slipping are provided on the other two sides of the bullseye platform 3. The limiting rods 12 are perpendicular to the movement direction of the main assembly conveyor line 2. Several bullseye bearings 13 are evenly distributed on the opposite surfaces of the two limiting rods 12 and on the bullseye platform 3 to reduce the pushing force of the operator to push the battery, making it labor-saving and convenient. Two roller conveyor lines 6 are hinged side by side on the frame 5 of the plate ear dispensing machine 4. The transport direction of the roller conveyor line 6 is perpendicular to the transport direction of the main assembly conveyor line 2 (arrow in the figure). The roller conveyor line 6 is driven to rotate by the rotating drive device 43. The rotating drive device 43 is a cylinder. The rotating drive device 43 is tilted between the frame 5 and the roller conveyor line 6. When the rotating drive device 43 extends to the position, the roller conveyor line 6 rotates and forms a 60° angle with the horizontal line. At this time, the internal electrode group plates of the battery 1 placed on the roller conveyor line 6 are arranged in 3 rows of different heights. When the rotating drive device 43 retracts, the roller conveyor line 6 is parallel to the horizontal line, and the upper surface of the roller of the roller conveyor line 6 is flush with the upper end surface of the bullseye bearing 13 on the bullseye platform 3. The glue gun 9 is fixed to the moving platform 11 of the linear module 8 via the glue gun angle adjustment device 10. The linear module 8 spans two roller conveyor lines 6 and is fixed on the frame 5. The glue gun 9 is moved laterally via the linear module 8, and the height and angle of the glue gun are adjusted via the glue gun angle adjustment device 10.

[0033] Furthermore, it also includes a glue tank (not shown in the figure), which is connected to the glue gun 9 via a glue pump and a hot melt glue tube.

[0034] like Figure 2-4 As shown, the roller conveyor line 6 has a battery positioning device, which includes a front baffle 61, a fixed side baffle 62, and a flat push plate 63. The front baffle 61 is located on the side away from the main assembly conveyor line 2, and this side is also the lower side after the roller conveyor line is flipped. The front baffle 61 is used to prevent the battery 1 from slipping after flipping. The front baffle 61 is covered with a rubber pad to prevent scratching the battery. Alternatively, the front baffle 61 can also be mounted on the top of a lifting cylinder. When the lifting cylinder is raised to the position, the front baffle protrudes from the upper plane of the roller conveyor line. When the lifting cylinder is lowered to the position, the front baffle is lower than the upper plane of the roller conveyor line. The fixed side baffle 62 and the flat push plate 63 are arranged opposite each other to restrict the position of the battery 1 from the left and right sides. The flat push plate 63 is mounted on the telescopic rod of the flat push cylinder 64. The fixed side baffle 62 is located on the closer side of two adjacent roller conveyor lines.

[0035] like Figure 5As shown, the glue gun angle adjustment device 10 includes a glue gun fixing rod 14 and an adjustment frame. The glue gun fixing rod 14 is connected to the adjustment frame with adjustable tilt angle and height. The adjustment frame includes an adjustment horizontal plate 15. One end of the adjustment horizontal plate 15 is connected to a long vertical rod 16 via a guide shaft support, and the other end has an elongated hole. A short vertical rod 17 is mounted at the elongated hole via the guide shaft support, and its assembly position can be adjusted along the elongated hole. The distance between the long vertical rod 16 and the short vertical rod 17 can be adjusted according to the length of the battery. The glue gun fixing rod 14 is tilted between the long vertical rod 16 and the short vertical rod 17 with adjustable height via cross clamps at both ends. The assembly height can be adjusted to use glue for batteries of different heights. The tilt angle of the glue gun fixing rod 14 is the same as the tilt angle after the roller conveyor line 6 is flipped. The glue guns 9 are three glue guns set according to the distribution requirements of the battery plate ears. After being positioned by the glue gun fixing rod 14, the three glue guns are directly opposite the three individual cells of the battery after being flipped on the roller conveyor line 6.

[0036] Furthermore, the frame 5 of the plate-ear dispensing machine 4 adopts a 60×60×3 square tube welded structure, with adjustable feet 9 at each of the four bottom corners. The feet 9 allow for height adjustment, ensuring the frame 1 is stably placed on the ground. The effective inner width of the roller conveyor 6 is 320 mm, made of 304 stainless steel, with a cylinder diameter of 50 mm and the center of the roller no more than 100 mm from the ground. The tilting drive device 43 enables the line 41 to switch between a horizontal position and a 60° angle with the ground. The tilting drive device 43 uses a cylinder with buffered air pressure. Since there are two stations that do not apply glue synchronously, if one station is applying glue, the shaking caused by the tilting of the other station may cause the glue gun to vibrate, affecting the glue application quality. The cylinder with buffered air pressure mitigates the vibration caused by the shaking, preventing any impact on glue application quality. The cylinder diameter of the tilting drive device 43 is no less than 63 mm to ensure stability during the tilting process. The linear module 8 uses a lead screw module with a stroke of 0.9 meters, a load of not less than 30 kg, a maximum speed of 0.5 m / s, and is equipped with a 0.4 kW servo motor 34. The glue gun 9 can slide back and forth along the movement direction of the linear module 8. The glue gun angle adjustment device 10 is used to connect and fix the glue gun 9 to the linear module 8.

[0037] In another embodiment, the bullseye platform 2 is made of 1200×1200×16mm nylon sheet, with a length and width of 1200mm and a thickness of 16mm. Multiple bullseye bearings 13 are mounted on the surface, with a spacing of 100mm between the bearings 13, for a total of 144 bearings 13. The bullseye platform 2 has switchable safety nets on both sides to prevent accidental contact by operators.

[0038] In another embodiment, there is a photoelectric switch on the roller conveyor line 6 to detect the battery's position. The PLC controller can collect the photoelectric switch signal and then control the roller conveyor line 6, the flipping drive device 43, the linear module 8, and the glue pump. Controlling the cylinder, motor, linear module, and pump by collecting signals through the PLC controller is prior art and is not the inventive point of this application. This embodiment will not be described in detail.

[0039] Usage process:

[0040] One operator pushes the battery 1, to be glued, horizontally onto the bullseye platform 3 via the main assembly conveyor line 2, rotates it 90 degrees, and feeds it into the first station of the plate ear glue dispensing machine 4 for glue application. After glue application, the battery is rotated 180 degrees on the bullseye platform, and another operator feeds it into the second station of the plate ear glue dispensing machine for further glue application. After glue application, the battery is moved horizontally back onto the main assembly conveyor line 2.

[0041] The battery 1 to be glued enters the roller conveyor line 6 and comes into contact with the front baffle 61. The roller conveyor line 6 is then rotated to a 60-degree angle with the horizontal by the tilting drive device 43, and then the battery is positioned left and right by the fixed side baffle 62 and the flat push plate 63. The linear module 8 controls the glue gun 9 to move towards the battery 1 to be glued and then apply glue. After the glue is applied, it moves back to the starting point. After standing still for 30 seconds, the roller conveyor line 6 returns to its initial position by the tilting drive device 43, and then the roller conveyor line rotates to send the battery out of the plate ear glue applicator 4.
