Description
Technical Field
[0001] This utility model relates to the field of lead-acid battery manufacturing, specifically to a battery electrode lug gluing machine. 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] The prior art discloses a lead-acid battery electrode lug gluing fixture, which consists of a frame, a linear motion module, a glue gun, and a battery positioning table. The linear motion module is mounted on the upper part of the frame; the battery positioning table is hinged to the lower part of the frame via a battery angle adjustment mechanism; and 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 table. Then, according to the battery length, the angle adjustment lever of the positioning table is manually operated to rotate the battery positioning table to the required angle. Glue is then applied, and the battery is allowed to cool. Afterward, the battery is manually or robotically rotated 180° for gluing on the other side. During the cooling and rotation, 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 to adjust the battery positioning table to the required angle. The existing glue-applying fixture only has fixed positioning baffles on the front and rear sides of the battery positioning table, and no positioning baffles are set on the left and right sides. When producing batteries of different sizes, in order to ensure that the starting position of the glue gun is aligned with the side of the gap between the inner electrode tabs of the battery, it is necessary to adjust the glue gun spacing and the placement point of the robot arm according to the different battery sizes. Adjusting the placement point of the robot arm is very cumbersome and cannot be completed by ordinary operators. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery electrode lug gluing machine that significantly improves the production efficiency of lead-acid batteries and makes the positioning more accurate.
[0006] Compared with the prior art, the present invention has the following advantages: a battery electrode group lug glue application machine, including a lug glue dispensing machine body;
[0007] The main body of the plate-ear dispensing machine includes a frame, a roller conveyor line, and a glue gun;
[0008] 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. Each roller conveyor line is equipped with a battery positioning device.
[0009] The battery positioning device includes a front baffle, a fixed side baffle, and a flat push plate;
[0010] The front baffle is located on the side with the lower horizontal height after the roller conveyor line is flipped, in order to prevent the battery from slipping off after flipping.
[0011] The fixed side baffle is positioned opposite the flat push plate and is used to restrict the position of the battery from both the left and right sides.
[0012] The glue gun is fixed to the moving platform of the linear module via a glue gun adjustment device, and the linear module spans two roller conveyor lines.
[0013] It also includes a glue box, which is connected to the glue gun via a hot melt glue tube.
[0014] Rubber pads are affixed to the front baffle, fixed side baffle, and flat push plate to prevent scratching the battery.
[0015] The flat push plate is mounted on the telescopic rod of the flat push cylinder, and 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.
[0016] The fixed side baffle is located on the closer side of the two adjacent roller conveyor lines.
[0017] The glue gun 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 horizontal plate, with a long vertical rod fixed at one end and a short vertical rod with an adjustable lateral position at the other end. The glue gun fixing rod is inclinedly installed 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 battery panel ears, and is installed and fixed on the glue gun fixing rod of the glue gun adjustment device.
[0021] The roller conveyor system designed in this utility model can switch between two working positions: horizontal and at a 60° angle to the ground. Combined with the positioning mechanism, it effectively solves the problem of insufficient adaptability of the battery positioning table 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.
[0022] The glue gun of this invention, with its glue gun adjustment device, can be flexibly adjusted according to different battery models, thus meeting the production needs of batteries of different sizes and quantities.
[0023] This invention adopts a modular design for the main frame and the dispensing components, which facilitates maintenance and replacement, reduces equipment maintenance costs, and extends service life. Attached Figure Description

[0029] like Figure 1-3As shown, the present invention provides a battery electrode group lug glue application machine, comprising a lug glue application machine body 4 and a glue tank (not shown in the figure). Two roller conveyor lines 6 are hinged side-by-side on the frame 5 of the lug glue application machine body 4. The roller conveyor lines 6 are rotated by a rotating drive device 43, which is a cylinder. The rotating drive device 43 is inclinedly mounted between the frame 5 and the roller conveyor lines 6. When the rotating drive device 43 extends to its position, the roller conveyor lines 6 rotate, forming a 60° angle with the horizontal line. At this time, the electrode group lugs inside the battery 1 placed on the roller conveyor lines 6 are arranged in three rows at different heights. When the rotating drive device 43 retracts, the roller conveyor lines 6 are parallel to the horizontal line. A glue gun 9 is fixed to the moving platform 11 of a linear module 8 via a glue gun adjustment device 10. The linear module 8 spans the two roller conveyor lines 6 and is fixed to the frame 5. The linear module 8 enables the horizontal movement of the glue gun 9, and the glue gun adjustment device 10 enables the adjustment of the glue gun's height and angle. The glue tank is connected to the glue gun 9 via a glue pump and a hot melt glue hose.
[0030] The roller conveyor 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 2, and this side is also the lower side after the roller conveyor 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 be mounted on the top of a lifting cylinder. When the lifting cylinder is raised to the correct position, the front baffle protrudes above the upper plane of the roller conveyor. When the lifting cylinder is lowered to the correct position, the front baffle is below the upper plane of the roller conveyor. 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 conveyors. The battery positioning device ensures that the left side wall of batteries of different sizes is flush with the fixed side baffle 62 and the front side wall is flush with the front baffle 61, thus achieving battery positioning. After positioning, it is only necessary to adjust the spacing of the glue gun on the glue gun fixing rod 14 to match the spacing of the battery cells. For batteries of different sizes, the starting point of glue dispensing is guaranteed to be uniform.
[0031] like Figure 4As shown, the glue gun 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 the three glue guns are positioned by the glue gun fixing rod 14, they are directly opposite the three individual cells of the flipped battery on the roller conveyor line 6. By adjusting the angle and height of the glue gun fixing rod 14, several glue guns can be adjusted simultaneously, which is convenient and quick.
[0032] The frame 5 of the plate-ear dispensing machine body 4 adopts a 60×60×3 square tube welded structure, with adjustable feet at all four corners of the bottom to ensure the frame 1 is stably placed on the ground. The effective inner width of the roller conveyor line 6 is 320 mm, made of 304 stainless steel, with a cylinder diameter of 50 mm and the center of the roller not exceeding 100 mm from the ground. The tilting drive device 43 can switch the line 41 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, the glue is not applied 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 can alleviate the vibration caused by the shaking and avoid affecting the glue application quality. The cylinder diameter of the tilting drive device 43 is not less than 63 mm to ensure the stability of 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 can slide back and forth along the movement direction of the linear module 8. The glue gun adjustment device 10 is used to connect and fix the glue gun 9 to the linear module 8.
[0033] 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.
[0034] When using this device, it can be equipped with a bullseye platform 3 or a robotic arm to load and unload batteries. Compared with the robotic arm solution, the bullseye platform 3 is more cost-effective. The bullseye platform 3 is located on one side of the main assembly conveyor line 2 of the battery 1, and the plate ear dispensing machine body 4 is located on the other side of the bullseye platform 3 and opposite to the main assembly conveyor line 2. 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 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. Limiting rods 12 are provided on the other two sides of the bullseye platform 3 to prevent the battery from slipping. 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, which reduces the pushing force of the operator to push the battery, making it labor-saving and convenient.
[0035] The specific operation process is as follows: One operator pushes the battery 1 to be glued via the main assembly conveyor line 2 to the bullseye platform 3, rotates it 90 degrees, and sends it into the first station of the plate ear glue dispensing machine body 4 for glue application. After glue application, it is rotated 180 degrees on the bullseye platform, and another operator continues to send it into the second station of the plate ear glue dispensing machine for glue application. After glue application is completed, the battery is moved horizontally to the main assembly conveyor line 2.
[0036] 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.
