Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery production, specifically to a tooling for automatically assembling photocells for lead-acid batteries. Background Technology

[0002] During the use of lead-acid batteries, a status indicator (commonly known as a photoelectric sensor) is usually installed on the battery cover to monitor electrolyte level and battery state of charge. Currently, photoelectric sensors are assembled manually, whereby a person places the sensor in the corresponding hole on the battery cover and then uses a rubber mallet to drive it in. However, this manual assembly method has the following problems: First, it requires a dedicated employee to handle the sensor assembly process, resulting in high labor costs and low production efficiency. Second, during manual installation, variations in the angle and force applied can easily damage the sensor or the battery cover, affecting product quality.

[0003] To address the aforementioned issue of photoelectric sensor installation, an automated photoelectric sensor assembly method is needed. Utility model patent CN202320762753 discloses an automatic photoelectric sensor installation method for lead-acid batteries, relating to the lead-acid battery manufacturing field. The method includes an installation housing with multiple horizontally connected installation platforms. A clamping structure for the photoelectric sensors is provided between the installation platforms and the housing. A rotary telescopic cylinder is connected to the bottom of the housing, and a vibrating rotary disc is located on one side of the housing. The discharge end of the vibrating rotary disc moves vertically downwards towards the trajectory of the installation platforms. This utility model features a four-station rotary installation structure. The photoelectric sensors, after being processed by the vibrating rotary disc, are sequentially installed onto the lead-acid batteries. Through intermittent operation of the conveyor belt, when the conveyor belt stops, the photoelectric sensor position is precisely below the sensor on the installation platform. With the cooperation of the installation structure, the photoelectric sensor can be accurately inserted into the lead-acid battery, greatly improving the efficiency of photoelectric sensor installation and significantly reducing labor costs. However, this automatic photocell installation device only aligns the photocell to the photocell opening in the battery compartment. It lacks any hammering device, which means that for photocells requiring tight assembly, hammering is necessary for proper installation. Otherwise, the assembly may be insecure, leading to detachment or electrolyte leakage. Furthermore, the disclosed automatic photocell installation device lacks a battery clamping device, resulting in low photocell assembly accuracy. Additionally, the fixed positions of the photocell clamping plate and installation platform limit its use to a single battery model, making it unsuitable for multiple battery models. In reality, the diverse battery models and varying photocell positions in production result in low utilization of existing automatic photocell assembly equipment. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tooling for automatically assembling lead-acid battery photocells. Equipped with a photocell hammer, the photocell can be smoothly installed into the photocell hole, effectively ensuring that the photocell is assembled in place. It is also applicable to the assembly of multiple battery models.

[0014] The fixed clamp, the first horizontal push cylinder, and the second horizontal push cylinder are all mounted on the frame on both sides of the battery conveying track via adjustable brackets.

[0015] The battery transport track entrance is equipped with a battery guide device, which includes guide plates arranged opposite each other. The two guide plates near the entrance of the battery transport track gradually form a horn shape outwards. The two guide plates are mounted on the frame on both sides of the battery transport track via adjustable brackets.

[0016] The top of the robotic arm is equipped with a pneumatic gripper for grasping photoelectric sensors.

[0017] The photoelectric hammer is mounted on the Z-axis linear motion module and can move vertically up and down with the Z-axis linear motion module.

[0018] The Z-axis linear motion module is mounted on the X-axis linear motion module and can move along the X-axis with the X-axis linear motion module. The X-axis linear motion module is horizontally mounted between the Y-axis linear motion module and the Y-axis slide rail and can move along the Y-axis with the Y-axis linear motion module.

[0019] It also includes a proximity switch for detecting the battery's position and a controller for receiving proximity switch signals to control the positioning of the battery positioning device, the movement of the robotic arm, and the vertical drive device.

[0027] like Figure 1-2This utility model provides a tooling for automatically assembling photocells for lead-acid batteries, including a battery transport track 10 for transporting batteries 9. A battery guide device is provided at the inlet end of the battery transport track 10. The battery guide device includes guide plates 12 arranged opposite each other. The two guide plates 12 near the inlet end of the battery transport track 10 gradually form a flared shape outwards. The distance between the other sides of the two guide plates 12 is slightly larger than the width of the battery. The two guide plates 12 are mounted on the frames on both sides of the battery transport track 10 via an adjustable bracket 13 to accommodate different battery models and facilitate adjustment of the distance between the two guide plates 12. The adjustable bracket 13 includes a fixed plate and two parallel connecting plates. One end of the connecting plate is fixed to the guide plate 12, and the other end has an elongated hole. The fixed plate is fixed to the outside of the frame of the battery transport track 10 and has mounting screw holes. After the guide plate 12 is adjusted and positioned, bolts pass through the elongated holes on the connecting plate and are inserted into the mounting screw holes on the fixed plate. The battery transport track 10 has a battery positioning device, which includes a fixed clamping plate 4, a movable clamping plate 6, and a forward baffle 2. The fixed clamping plate 4 and the movable clamping plate 6 are arranged parallel to each other on both sides of the battery transport track 10. The movable clamping plate 6 is mounted on the top of the push rod of the first horizontal push cylinder 5, and the forward baffle 2 is mounted on the top of the push rod of the second horizontal push cylinder 11. When the battery 9 is in place, the second horizontal push cylinder 11 drives the forward baffle 2 to push out, and the forward baffle 2 blocks the front end of the battery 9. The first horizontal push cylinder 5 drives the movable clamping plate 6 to push out, clamping the battery 9 between the fixed clamping plate 4 and the movable clamping plate 6. The fixed clamping plate 4, the first horizontal push cylinder 5, and the second horizontal push cylinder 11 are all mounted on the frame on both sides of the battery transport track 10 via an adjustable bracket 2 (which can be the same structure as the adjustable bracket 13, or any other existing bracket that can achieve this function) to accommodate the assembly of different battery models.A vibrating rotary disk 1 is located on one side of the battery conveying track 10. It contains battery photocells. The vibrating rotary disk 1 is an existing structure; vibration allows the photocells to be arranged vertically at the discharge port. On one side of the battery conveying track 10, there is also a robotic arm 3 and a photocell hammer 8 for gripping the photocells. The top of the robotic arm 3 is equipped with a pneumatic gripper for gripping the photocells. After gripping the photocells at the discharge port of the vibrating rotary disk 1, the robotic arm 3 positions them within the photocell holes of the battery 9. The discharge end of the vibrating rotary disk 1 faces the robotic arm 3. When producing different battery models, the robotic arm can be adjusted to ensure accurate insertion of the photocells into the photocell holes. The photocell hammer 8 is mounted on the Z-axis linear motion module 7. 3. The Z-axis linear motion module 73 can be vertically raised and lowered with the Z-axis linear motion module 73. The Z-axis linear motion module 73 is mounted on the X-axis linear motion module 71 and can move along the X-axis with the X-axis linear motion module 71. The X-axis linear motion module 71 is horizontally mounted between the Y-axis linear motion module 72 and the Y-axis slide rail 74 and can move along the Y-axis with the Y-axis linear motion module 72. When producing different types of batteries, the photoelectric hammer 8 is adjusted to be directly above the photoelectric hole after the battery 9 is positioned by adjusting the X-axis linear motion module 71, the Y-axis linear motion module 72 and the Z-axis linear motion module 73. The Y-axis linear motion module 72 and the Y-axis slide rail 74 are supported by the frame 17. It also includes a proximity switch 15 for detecting the battery's position and a controller for receiving the signal from the proximity switch 15 and controlling the positioning of the battery positioning device, the movement of the robotic arm and the Z-axis linear motion module 73. The controller receiving signals and controlling the movement of the robotic arm, cylinder and linear motion module is existing technology and will not be described in detail in this embodiment.

[0028] In use, the photocells to be installed are placed into the feed inlet of the vibrating rotary table 1. Under the action of the vibrating rotary table 1, the photocells are arranged neatly and transported to the discharge outlet, which is 10-20 mm wide. The pneumatic fingers at the tip of the robotic arm 3 remove the photocells from the discharge outlet. The robotic arm 3 rotates to above the battery cover, positioning the photocells directly above their holes. The battery 9 moves along the battery transport track 10 and, once in place, is fixed by the battery positioning device. The robotic arm 3 inserts the photocell into its hole, then releases its grip. The Z-axis linear motion module 73 drives the photocell hammer 8 downwards, driving the photocell hammer into the battery cover. The photocell hammer 8 then returns to its initial position, completing the photocell assembly. This method improves assembly efficiency and avoids damage to the photocells or battery cover caused by variations in force and angle during manual assembly.
