Description

Technical Field

[0001] This utility model relates to the technical field of battery production equipment, specifically to a device for applying adhesive to the tabs of automotive lead-acid batteries. Background Technology

[0002] Most commercial vehicles currently use a rear-mounted or stacked battery design. The advantage of this arrangement is that it frees up space for other energy-saving and emission-reduction equipment. However, with rear-mounted or stacked batteries, the vibration acceleration during vehicle operation is significantly higher compared to the original battery installation location. This can lead to battery failure modes such as broken lugs, broken grid bars, and busbar breakage, thus reducing the battery's lifespan.

[0003] The main vibration failure symptom of existing automotive batteries is the breakage of the lug at the junction of the busbar and the lug under the positive and negative terminals. Current effective solutions involve adding hot melt adhesive to the gap between the busbar and the lug. The adhesive application fixture 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; and the glue gun is fixed to the linear motion module via a glue gun angle adjustment mechanism. In use, the positioning platform angle adjustment lever is manually operated to rotate the platform to the required angle according to the battery length. Then, the battery is manually or by a robotic arm to move it to the positioning platform for adhesive application, followed by static cooling and curing. The battery is then rotated 180° by the robotic arm for adhesive application on the other side. During static cooling and rotation, the glue gun is in a waiting state, severely impacting production efficiency. The battery angle adjustment mechanism is complex, requiring manual operation to adjust the extension and retraction of the positioning platform to the required angle. There is no device to accelerate the cooling of the hot melt adhesive, resulting in excessively long natural cooling time. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glue-adding device for the tabs of automotive lead-acid batteries, which accelerates the cooling of hot melt glue, reduces the settling time, and significantly improves the production efficiency of lead-acid batteries.

[0005] A glue-applying device for the tabs of a lead-acid battery for vehicles includes a forward dual-station glue dispensing machine, a transition roller conveyor line, a reverse dual-station glue dispensing machine, and a hot melt glue cooling module.

[0006] The forward dual-station dispensing machine includes a frame, a roller conveyor line, and a glue gun;

[0007] The roller conveyor consists of two lines, which are hinged side by side within the frame, and each roller conveyor can be rotated by the rotation drive device.

[0008] The glue gun is fixed to the two-axis linear module via a glue gun angle adjustment device;

[0009] The reverse dual-station dispensing machine has the same structure as the forward dual-station dispensing machine. The included angle after the upper roller conveyor line of the reverse dual-station dispensing machine is flipped is complementary to the included angle after the upper roller conveyor line of the forward dual-station dispensing machine is flipped.

[0010] The transition roller conveyor line is located between the forward / reverse dual-station dispensing machine. There are two transition roller conveyor lines, and they correspond one-to-one with the two roller conveyor lines of the forward / reverse dual-station dispensing machine.

[0011] The hot melt adhesive cooling module is mounted on the transition roller conveyor line and is used to cool the hot melt adhesive in the battery compartment after it has been dispensed by the forward / reverse dual-station dispensing machine.

[0012] It also includes a glue box, which is connected to the glue gun via a hot melt glue tube.

[0013] Each roller conveyor line on the forward dual-station dispensing machine and the reverse dual-station dispensing machine is equipped with a front baffle, a fixed side baffle, and a flat push plate for positioning the battery.

[0014] 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.

[0015] The front baffle is located at the lower end of the roller conveyor after it is flipped, and is used to prevent the battery from slipping off after flipping. The front baffle is installed 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 two adjacent roller conveyor lines.

[0017] The glue gun angle adjustment device includes a glue gun fixing rod and an adjustment frame. The glue gun fixing rod is angle-adjustable and connected to the lower part of the adjustment frame. The upper end of the adjustment frame is fixed to one end platform of the Z-axis linear module of the two-axis linear module.

[0018] The adjustment frame includes an adjustment horizontal plate, one end of which is fixed with a long vertical rod and the other end with a short vertical rod whose horizontal position is adjustable. The glue gun fixing rod is inclinedly fixed 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 two-axis linear module includes a Y-axis linear module and a Z-axis linear module. The Y-axis linear module spans across the two roller conveyor lines, and the Z-axis linear module is assembled on the moving platform of the Y-axis linear module.

[0021] 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.

[0022] Each of the aforementioned transition roller conveyors has a battery guiding device, which consists of two guide chains with adjustable relative positions. The two guide chains at the battery inlet end open outward in a trumpet shape.

[0023] The transition roller conveyor line is equipped with baffles at intervals, and the baffles are mounted on the top of the baffle lifting cylinder.

[0024] The hot melt adhesive cooling module includes a robotic arm and a blower head mounted on the top of the robotic arm;

[0025] The robotic arm is mounted at the top center of the support frame;

[0026] There are multiple blower heads, each corresponding to a glue gun. The multiple blower heads are connected to a compressed cold air source via air tubes.

[0027] This invention is equipped with a device for blowing hot melt adhesive. The batteries at the two stations of the forward / reverse dual-station dispensing machine are alternately filled with adhesive and then left to stand. The hot melt adhesive cooling module alternately blows air onto the batteries at all four stations of the forward / reverse dual-station dispensing machine to accelerate cooling. The battery standing time is shortened from 30 seconds to less than 15 seconds, effectively reducing the battery standing time and improving efficiency.

[0028] This invention employs a dual-station hot melt adhesive filling system for both forward and reverse dispensing machines to fill the gaps between the battery electrode plates. After dispensing at the first station and allowing it to settle, the dispensing gun dispenses adhesive at the second station. Once the second station has finished dispensing, the first station is cooled by the hot melt adhesive cooling module. When the next battery is replaced, the dispensing gun can continue dispensing adhesive at the first station. This process is repeated, allowing for continuous production with high efficiency.

[0029] This invention effectively solves the problems of complex production processes, large workload, and long time consumption under traditional operation methods, and significantly improves the production efficiency of lead-acid batteries.

[0030] The roller conveyor of this invention can operate in two positions: horizontal transport and flipping for gluing. The flipping drive device can be a pneumatic cylinder or a hydraulic cylinder. It has a simple structure and high flipping efficiency. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0045] like Figure 1-3This is one embodiment of the lead-acid battery tab gluing device of this utility model, used for gluing the top tabs of lead-acid batteries. The device is located on the main assembly conveyor line and consists of a forward dual-station dispensing machine 4, a transition roller conveyor line 5, a reverse dual-station dispensing machine 7, a hot melt adhesive cooling module 6, and a glue tank 9. The transition roller conveyor line 5 is located between the forward dual-station dispensing machine 4 and the reverse dual-station dispensing machine 7. There are two transition roller conveyor lines 5, each corresponding one-to-one with the two roller conveyor lines of the forward / reverse dual-station dispensing machine. The hot melt adhesive cooling module 6 is mounted on the transition roller conveyor line 5 and is used to cool the hot melt adhesive in the battery compartment after dispensing by the forward / reverse dual-station dispensing machine. The glue tank 9 is connected to the glue gun 49 on the forward / reverse dual-station dispensing machine through a glue pump and a hot melt adhesive pipe.

[0046] like Figure 4-6 As shown, the forward dual-station dispensing mechanism 4 includes a frame 45, roller conveyor lines 46, and glue guns 49. There are two roller conveyor lines 46, which are hinged side by side in the frame 45. The frame 45 has a flipping drive device 43 for driving the roller conveyor lines 46 to flip. The glue guns 49 are multiple glue guns set according to the distribution requirements of the battery panel ears. The multiple glue guns are fixed to the two-axis linear module via a glue gun angle adjustment device 410. The two-axis linear module includes a Y-axis linear module 48 and a Z-axis linear module 411. The Y-axis linear module 48 spans across the two roller conveyor lines 46. The Z-axis linear module 411 is mounted on the moving platform of the Y-axis linear module 48. The Z-axis linear module 411 can translate with the Y-axis linear module 48 in a direction perpendicular to the battery conveying direction.

[0047] like Figure 7 As shown, each roller conveyor line on the forward dual-station dispensing mechanism 4 is equipped with a front baffle 461, a fixed side baffle 462, and a flat push plate 463 for positioning the battery 1. The front baffle 461 is located on the side with the lower horizontal height after the roller conveyor line is flipped, to prevent the battery 1 from slipping after flipping. The front baffle 461 is mounted on the top of the lifting cylinder 465. When the lifting cylinder 465 is raised to the position, the front baffle 461 protrudes from the upper plane of the roller of the roller conveyor line. When the lifting cylinder 465 is lowered to the position, the front baffle 461 is lower than the upper plane of the roller of the roller conveyor line. The fixed side baffle 462 is located on the side closer to the two adjacent roller conveyor lines. The fixed side baffle 462 is set opposite to the flat push plate 463 to restrict the position of the battery 1 from the left and right sides. The flat push plate 463 is mounted on the telescopic rod of the flat push cylinder 464.

[0048] like Figure 8As shown, the glue gun angle adjustment device 410 includes a glue gun fixing rod 414 for mounting the glue gun 49 and an adjustment frame. The glue gun fixing rod 414 is angle-adjustable and connected to the adjustment frame. The upper end of the adjustment frame is fixed to one end platform of the Z-axis linear module 411 of the two-axis linear module. The adjustment frame can be vertically raised and lowered with the Z-axis linear module 411. The adjustment frame includes an adjustment horizontal plate 415. A long vertical rod 416 is fixed to one end of the adjustment horizontal plate 415, and an elongated hole is provided on the other end. A short vertical rod 417 is installed at the elongated hole, which can be moved along the elongated hole to adjust the assembly position. The distance between the long vertical rod 416 and the short vertical rod 417 can be adjusted according to the length of the battery. The glue gun fixing rod 414 is inclined and fixed between the long vertical rod 416 and the short vertical rod 417. The inclination angle of the glue gun fixing rod 414 is the same as the inclination angle after the roller conveyor line is flipped.

[0049] like Figure 9-10 As shown, the transition roller conveyor line 5 has a battery guiding device 12, which consists of two guide chains with adjustable relative positions. The two guide chains at the battery inlet end open outward in a trumpet shape. The two guide chains are equipped with parallel rollers on opposite sides. The rollers are made of rubber to avoid damaging the battery. The guide chains are installed at the top of the crossbar. The rear end of the crossbar passes through the top of the vertical plate. The lower end of the vertical plate is fixed to the conveyor frame. The vertical plate is provided with a threaded countersunk hole, which communicates with the through hole through the crossbar. The threaded countersunk hole is equipped with a screw that can hold the top of the crossbar against it to prevent the crossbar from shifting.

[0050] like Figure 11-12 As shown, the hot melt adhesive cooling module 6 includes a robotic arm 61 and blowers 62 mounted on the lower end of the robotic arm. There are multiple blowers 62, each corresponding to a glue gun 49. The multiple blowers 62 are connected to a compressed cold air source via air pipes. The upper end of the robotic arm 61 is mounted on the top center of the support frame 63. The robotic arm 61 is supported by the support frame 63 above the transition roller conveyor line 5. It can blow air to the four stations of the forward dual-station dispensing machine 4 and the reverse dual-station dispensing machine 7 to accelerate the cooling of the hot melt adhesive in the battery compartment.

[0051] like Figure 13 As shown, the reverse dual-station dispensing mechanism 7 has the same structure as the forward dual-station dispensing mechanism 4. The included angle of the roller conveyor line on the reverse dual-station dispensing mechanism 7 after flipping is complementary to the included angle of the roller conveyor line 46 on the forward dual-station dispensing mechanism 4 after flipping.

[0052] In another embodiment, a PLC controller is also included, such as Figure 1 , 2As shown, the transition roller conveyor line 5 is divided into multiple battery positions by a baffle plate 11. The baffle plate 11 is mounted on the top of the baffle lifting cylinder. When the baffle lifting cylinder extends to its position, the baffle plate 11 protrudes above the upper surface of the roller conveyor line. When the baffle lifting cylinder retracts to its position, the baffle plate 11 is below the upper surface of the roller conveyor line. Each battery position has a photoelectric switch for sensing the battery. The PLC controller controls the baffle lifting cylinder to operate after detecting the battery through the photoelectric switch, preventing the batteries from colliding. The forward / reverse dual-station dispensing machine has a photoelectric switch for sensing the battery. After the PLC controller determines the battery position based on each photoelectric switch, it controls the motors, cylinders, and linear modules on the forward dual-station dispensing machine 4, the transition roller conveyor line 5, the reverse dual-station dispensing machine 7, and the hot melt adhesive cooling module 6 to operate, as well as control the dispensing pump to dispense adhesive and open the solenoid valve on the air pipe to blow air. Controlling the cylinders, motors, linear modules, pumps, and solenoid valves by collecting signals through the PLC controller is prior art and not the inventive point of this application. This embodiment will not elaborate further.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
