Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, specifically a four-station commercial vehicle battery top gluing device. Background Technology

[0002] Most commercial vehicles currently employ 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. For heavy-duty trucks, the rear-end conditions are even more severe. This can lead to battery failure modes such as broken plate lugs, broken grid bars, and broken busbars, reducing the battery's lifespan.

[0003] The main vibration failure symptom of existing commercial vehicle 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 practice, 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. Furthermore, the battery angle adjustment mechanism is complex and requires manual adjustment to adjust the battery positioning platform to the required angle. If a robotic arm is used to handle batteries, and speed is increased by expanding the workstations, one robotic arm cannot meet the requirements of multiple workstations, while multiple robotic arms require a large amount of space and are relatively expensive. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a four-position commercial vehicle battery top gluing device, which significantly improves the production efficiency of lead-acid batteries.

[0005] A four-station commercial vehicle battery top glue application device is connected to the main assembly conveyor line, including a line-splitting module, a forward dual-station glue dispensing machine, a transition roller conveyor line, a reverse dual-station glue dispensing machine, and a parallel line module arranged sequentially along the battery conveying direction.

[0006] The dividing module is used to divide the single row of batteries on the main assembly conveyor line at the front end of the dispensing into two rows.

[0007] The forward dual-station dispensing machine includes a frame, a roller conveyor line, and a glue gun;

[0008] 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.

[0010] There are two transition roller conveyor lines, each corresponding one-to-one with the two roller conveyor lines of the forward dual-station dispensing machine.

[0011] 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.

[0012] The parallel module is used to transport the double-row batteries after dispensing to the main assembly conveyor line at the rear end.

[0013] It also includes a glue box, which is connected to the glue gun via a hot melt glue tube.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] The fixed side baffle is located on the closer side of two adjacent roller conveyor lines.

[0018] 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.

[0019] 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.

[0020] The tilt angle of the glue gun fixing rod is the same as the tilt angle after the roller conveyor line is flipped.

[0021] 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.

[0022] 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.

[0023] Both the main assembly conveyor line and the transition roller conveyor line have battery guiding devices. The battery guiding device consists of two guide chains with adjustable relative positions. The two guide chains at the battery inlet end open outward in a trumpet shape.

[0024] The main assembly conveyor line, the branch line module, the transition roller conveyor line and the parallel line module are all equipped with baffles at intervals, and the baffles are mounted on the top of the baffle lifting cylinder.

[0025] The splitting module includes a double-row roller conveyor line and a pushing mechanism for pushing batteries.

[0026] The pushing mechanism includes a battery push plate and a pushing cylinder. The battery push plate is mounted on the front end of the telescopic rod of the pushing cylinder. The upper end of the battery push plate protrudes from the upper end of the double-row roller conveyor line. The battery push plate has a notch for the clearance roller.

[0027] The battery push plate has parallel guide posts at both ends. The guide posts are installed in linear bearings fixed on the battery push plate, and the two ends of the guide posts are fixed to the double-row roller conveyor line.

[0028] The parallel module has the same structure as the split module, but the pushing direction of the pushing mechanism on the parallel module is opposite to that on the split module.

[0029] This utility model adopts a four-station production line connected to the main assembly line at the same time, realizing hot melt adhesive filling of the gap between the battery electrode group plates, effectively solving the problems of complex production process, large workload and long time consumption under the traditional operation method, significantly improving the production efficiency of lead-acid batteries; and it occupies less space than the solution of adding a robot, has a wide range of applications and low cost.

[0030] The glue application device of this utility model has a set of glue guns corresponding to two workstations for glue application. When one workstation is cooling, the other workstation is in the glue application state. The glue guns are in continuous production throughout the entire production process, and there is no need to move the battery 180° to rotate during the production process, which effectively improves production efficiency.

[0031] 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.

[0032] This invention is applicable to the production of different battery models.

[0047] 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.

[0048] like Figure 1-2This is one embodiment of the four-station commercial vehicle battery top glue application device of the present invention, used for applying glue to the top electrode group lugs of lead-acid batteries. It consists of a branching module 3, a forward dual-station glue dispensing machine 4, a transition roller conveyor line 5, a reverse dual-station glue dispensing machine 7, a parallel module 8, and a glue tank 9 arranged sequentially along the battery conveying direction. The glue tank 9 is connected to the glue gun 49 on the forward / reverse dual-station glue dispensing machine through a glue pump and a hot melt glue pipe.

[0049] like Figure 1-3 As shown, since the batteries on the main assembly conveyor line 2 are supplied from a single line, in order to match the two forward and reverse dual-station dispensing machines of this application, a dividing module 3 is set up to divide the single row of batteries 1 on the main assembly conveyor line 2 at the dispensing front end into a double row. The dividing module 3 includes a double-row roller conveyor line 32 and a pushing mechanism 31 for pushing the batteries 1.

[0050] like Figure 4 As shown, the pushing mechanism 31 includes a battery push plate 311 and a pushing cylinder 312. The battery push plate 311 is mounted on the front end of the telescopic rod of the pushing cylinder 312. The upper end of the battery push plate 311 protrudes from the upper end of the double-row roller conveyor line 32. The battery push plate 311 has a notch for the clearance roller. The battery push plate 311 has parallel guide posts 314 at both ends. The guide posts are inserted into linear bearings fixed on the battery push plate 311. The two ends of the guide posts 314 are fixed to the double-row roller conveyor line 32.

[0051] like Figure 5-7 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.

[0052] like Figure 8As 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.

[0053] like Figure 9 As 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.

[0054] like Figure 10 , 11 As shown, there are two transition roller conveyor lines 5, which correspond one-to-one with the two roller conveyor lines 46 of the forward dual-station dispensing mechanism 4.

[0055] like Figure 12 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.

[0056] like Figure 13 As shown, after the dispensing is completed, the batteries of the two lines need to be connected in parallel before being sent to the main assembly conveyor line 2 at the rear end. Therefore, a paralleling module 8 is set up. The structure of the paralleling module 8 is the same as that of the splitting module 3. The pushing direction of the pushing mechanism on the paralleling module 8 is opposite to that of the pushing direction of the pushing mechanism on the splitting module 3.

[0057] In another embodiment, such as Figure 1 , 2As shown in Figures 10 and 11, both the main assembly conveyor line 2 and the transition roller conveyor line 5 have... electricity The battery guide device 12 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 opposite sides of the two guide chains are composed of parallel rollers made of rubber to avoid damaging the battery. The guide chains are mounted on 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 has a threaded countersunk hole that communicates with the through hole through the crossbar. The threaded countersunk hole contains a screw that can hold the top of the crossbar against it to prevent the crossbar from shifting.

[0058] In another embodiment, a PLC controller is also included, such as Figure 1 , 2 As shown, each row of roller conveyors 32 in the main assembly conveyor line 2, each row of roller conveyors 5 in the branching module 3, and each row of roller conveyors in the paralleling module 8 are divided into multiple battery positions by baffle plates 11. The baffle plates 11 are 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 photoelectric switch, preventing batteries from colliding. The forward / reverse dual-station dispensing machine has photoelectric switches for sensing batteries. After the PLC controller determines the battery position based on the photoelectric switches, it controls the motors, cylinders, and linear modules on the branching module 3, the forward dual-station dispensing machine 4, the transition roller conveyor line 5, the reverse dual-station dispensing machine 7, and the parallel module 8 to operate, and controls the dispensing pump to dispense glue. The method of controlling the cylinders, motors, linear modules, and pumps 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.

[0059] Usage process:

[0060] Batteries from the main assembly conveyor line 2 are split by the splitting module 3 and enter the forward dual-station dispensing machine 4. After the roller conveyor line 46 of the forward dual-station dispensing machine 4 is flipped, the glue pump is turned on to apply glue to one side of the battery at one station. After being allowed to cool, the batteries enter the first station of the reverse dual-station dispensing machine 7 via the transition roller conveyor line 5. The roller conveyor line 46 of the first station of the reverse dual-station dispensing machine 7 is flipped in the opposite direction to apply glue to the other side of the battery. After being allowed to cool, the batteries are sent back to the main assembly conveyor line 2 after being connected by the paralleling module 8, completing the glue application. Meanwhile, while the battery at one station of the forward dual-station dispensing machine 4 is cooling, the glue gun continues to apply glue to the battery at the second station. After cooling, the battery enters the second station of the reverse dual-station dispensing machine 7 via another roller conveyor line 5. The roller conveyor line 46 of the second station of the reverse dual-station dispensing machine 7 flips in the opposite direction to apply glue to the other side of the battery. After being allowed to cool, the battery is sent back to the main assembly conveyor line 2 via the parallel module 8 to complete the glue application. Parallel production improves efficiency.
