Description

Technical Field

[0001] This invention relates to the field of battery assembly, and in particular to a tire pressure sensor battery assembly device. Background Technology

[0002] Tires are widely used in various fields. To ensure safety, tire pressure monitoring is necessary. Therefore, tire pressure sensors are installed inside tires to monitor tire pressure, ensure consistent tire pressure, and improve tire lifespan. The working principle of a tire pressure sensor is that the sensor detects the tire pressure, processes the data through a chip, and transmits it to a receiver. The receiver then processes the data and displays it on a screen.

[0003] With the shortage of labor costs and manpower, the demand for tire pressure sensors has increased significantly. Manual assembly is difficult, prone to missing parts, and results in a poor pass rate. Mechanical assembly requires aligning each battery pin to ensure correct placement, which is cumbersome, inefficient, and can damage battery pins, further affecting the yield.

[0004] Therefore, how to provide an accurate and efficient tire pressure sensor battery assembly device is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a tire pressure sensor battery assembly device that uses a vision camera to identify and position the battery, and uses a secondary positioning mechanism to detect whether the pins are qualified, thereby improving the accuracy and efficiency of battery assembly.

[0006] To address the aforementioned technical problems, this invention provides a tire pressure sensor battery assembly device, comprising a frame and a loading bin, a camera guiding mechanism, a robotic arm, and a secondary positioning mechanism mounted on the frame. The camera guiding mechanism is located above the loading bin and is used to locate and identify the batteries within the loading bin. The robotic arm sequentially picks up the batteries from the loading bin and transports them to the secondary positioning mechanism. The secondary positioning mechanism is used to individually check whether the battery pins are qualified. The robotic arm then assembles the qualified batteries onto the sensor.

[0007] Preferably, the camera guiding mechanism includes an X-axis fixing plate, an X-axis driver and a Y-axis fixing plate are disposed below the X-axis fixing plate, a Y-axis driver and a camera bracket are disposed below the Y-axis fixing plate, and a downward-facing guiding vision camera and a light source are mounted on the camera bracket.

[0008] Preferably, the X-axis driver and the Y-axis driver are specifically electric cylinders.

[0009] Preferably, the robotic arm is connected to a pneumatic gripper mechanism, and the pneumatic gripper mechanism is equipped with a vacuum suction cup and a vacuum generator.

[0010] Preferably, the pneumatic gripper mechanism is provided with a pin fixing block.

[0011] Preferably, the secondary positioning mechanism includes a fixed plate, a positioning frame is provided at the upper end of the fixed plate, a positioning claw and a positioning driver for driving the two positioning claws to clamp the battery are installed on the positioning frame, and a positioning vision camera with an upward-facing lens is installed at the lower end of the fixed plate. The positioning vision camera takes pictures of the battery clamped by the two positioning claws through the notch in the middle of the positioning frame.

[0012] Preferably, the positioning frame is equipped with a photoelectric switch and a proximity switch.

[0013] Preferably, the frame is equipped with an NG tray for holding non-conforming products.

[0014] Preferably, the outer periphery of the frame is provided with a panel, anti-static glass, and a safety door.

[0016] This invention provides a tire pressure sensor battery assembly device, including a frame and a loading box, a camera guiding mechanism, a robotic arm, and a secondary positioning mechanism mounted on the frame. The camera guiding mechanism is located above the loading box and is used to locate and identify the batteries in the loading box. The robotic arm sequentially picks up the batteries in the loading box and transports them to the secondary positioning mechanism. The secondary positioning mechanism is used to check whether the pins of the batteries are qualified one by one. The robotic arm assembles the qualified batteries onto the sensor.

[0017] During assembly, multiple batteries are placed in a loading bin. A camera-guided mechanism captures images of the batteries in the bin, enabling positioning and identification. A robotic arm then sequentially picks up the batteries and transports them to a secondary positioning mechanism. At this mechanism, each battery's pins are individually inspected for compliance. The robotic arm then assembles the qualified batteries onto sensors. By using a vision camera to identify and position the batteries, and because the robotic arm positions them correctly, mechanical guidance is unnecessary. Furthermore, the secondary positioning mechanism ensures high yield rates and improves assembly accuracy and efficiency. Attached Figure Description

Detailed Implementation

[0025] The core of this invention is to provide a tire pressure sensor battery assembly device that uses a vision camera to identify and position the battery, and uses a secondary positioning mechanism to detect whether the pins are qualified, thereby improving the accuracy and efficiency of battery assembly.

[0026] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a specific embodiment of the tire pressure sensor battery assembly equipment provided by the present invention; Figure 2 This is a schematic diagram from another perspective of a specific embodiment of the tire pressure sensor battery assembly equipment provided by the present invention.

[0028] This invention provides a tire pressure sensor battery assembly device, including a frame 1 and a loading box 2, a camera guide mechanism 3, a robotic arm 4, and a secondary positioning mechanism 5 mounted on the frame 1. The camera guide mechanism 3 is located above the loading box 2 and is used to locate and identify the batteries in the loading box 2. The robotic arm 4 sequentially picks up the batteries in the loading box 2 and transports them to the secondary positioning mechanism 5. The secondary positioning mechanism 5 is used to check whether the pins of the batteries are qualified one by one. The robotic arm 4 assembles the qualified batteries onto the sensor.

[0029] During assembly, multiple batteries are placed in the loading bin 2. The camera guiding mechanism 3 captures images of the batteries in the loading bin 2, performs positioning and identification, and controls the robotic arm 4 to sequentially pick up the batteries from the loading bin 2 and transport them to the secondary positioning mechanism 5. At the secondary positioning mechanism 5, each battery pin is checked for compliance. The robotic arm 4 then assembles the qualified batteries onto the sensors. By using a vision camera to identify and position the batteries, and because the robotic arm 4 positions the batteries correctly, no mechanical guidance is needed. Furthermore, the secondary positioning mechanism 5 checks the pin compliance, ensuring a high yield rate and improving the accuracy and efficiency of battery assembly.

[0030] Please refer to Figures 3 to 6 , Figure 3 A schematic diagram of the camera guiding mechanism in a specific embodiment of the tire pressure sensor battery assembly equipment provided by the present invention; Figure 4 This is a schematic diagram of the pneumatic gripper mechanism in a specific embodiment of the tire pressure sensor battery assembly equipment provided by the present invention. Figure 5 This is a schematic diagram of the secondary positioning mechanism in a specific embodiment of the tire pressure sensor battery assembly equipment provided by the present invention. Figure 6 This is a schematic diagram of the frame structure in one specific embodiment of the tire pressure sensor battery assembly equipment provided by the present invention.

[0031] Specifically, the camera guiding mechanism 3 includes an X-axis fixing plate 31, an X-axis driver 32, an X-axis fixing plate 33, and an X-axis driver 34. The X-axis driver 32 and the X-axis fixing plate 33 are located below the X-axis fixing plate 31. The X-axis fixing plate 31 is fixed to the frame 1. The X-axis driver 32 is mounted on the X-axis fixing plate 31, and its output end is connected to the X-axis fixing plate 33. The X-axis driver 34 and the camera bracket 35 are located below the X-axis fixing plate 33. The X-axis driver 34 is mounted on the X-axis fixing plate 33. A downward-facing guide vision camera 36 and a light source 37 are mounted on the camera bracket 35. The camera bracket 35 is connected to the guide vision camera 36 via a guide camera adjustment seat 38 for adjusting and aligning the guide vision camera 36 before operation. Specifically, the X-axis driver 32 and the X-axis driver 34 are drive electric cylinders and are equipped with an X-axis guide rail 39 and a Y-axis guide rail 310. During operation, the X-axis driver 32 drives the X-axis fixed plate 33 to move along the X-axis, and the X-axis driver 34 drives the camera bracket 35 to move along the Y-axis, thereby driving the guide vision camera 36 to move in both the X-axis and Y-axis directions.

[0032] Furthermore, the robotic arm 4 is connected to a pneumatic gripper mechanism 41, which contains a vacuum suction cup 42 and a vacuum generator. The pneumatic gripper mechanism 41 is equipped with an X-axis adjustment component 44 and a Y-axis adjustment component 45. During the process of the robotic arm 4 picking up the battery from the hopper and transporting it to the secondary positioning mechanism 5, precise alignment is not required, and the vacuum suction cup 42 is used to pick up the battery. When the battery is assembled onto the sensor, precise alignment is required, and the pneumatic gripper mechanism 41 is used to pick up the battery. During this process, the pin fixing block 43 on the pneumatic gripper mechanism 41 fixes the battery pins.

[0033] In the tire pressure sensor battery assembly equipment provided in a specific embodiment of the present invention, the secondary positioning mechanism 5 includes a fixed plate 51. A positioning frame 52 is provided on the upper end of the fixed plate 51. Positioning claws 53 and a positioning driver 54 for driving the two positioning claws 53 to clamp the battery are installed on the positioning frame 52. A positioning vision camera 55 with its lens facing upward is installed on the lower end of the fixed plate 51. The positioning vision camera 55 takes pictures of the battery clamped by the two positioning claws 53 through the notch in the middle of the positioning frame 52. The positioning vision camera 55 is connected to the fixed plate 51 through a positioning camera adjustment seat 58. Further, a through-beam switch 56 and a proximity switch 57 are provided on the positioning frame 52.

[0034] Based on the tire pressure sensor battery assembly equipment provided in the above specific embodiments, an NG material tray 6 for holding defective products is installed on the frame 1.

[0035] The specific work process is as follows:

[0036] Loading: The robotic arm 4 returns to the initial picking end, and the operator places the loading box 2, which is full of batteries, into the picking position. The picking position has XY-direction guards to position the loading box 2, facilitating quick and accurate loading by the operator. After loading is completed, the operator exits the equipment and presses the equipment start button. The guiding vision camera 36 receives the instruction and moves to the appropriate position to start taking pictures of the batteries and automatically detecting and calculating. The results are transmitted to the robotic arm 4. After receiving the instruction, the robotic arm 4 establishes a relative three-dimensional coordinate system based on the image. According to the relative calculation results, the robotic arm 4 grasps the product. During the grasping, the detection sensor detects the battery, and the controller sends an instruction to the vacuum suction cup 42. The vacuum suction cup 42 works to pick up the battery. The robotic arm 4 transports the grasped battery to the secondary positioning mechanism 5. After receiving the sensor signal from the secondary positioning mechanism 5, the vacuum suction cup 42 stops working, and the loading is completed.

[0037] Secondary positioning: After the through-beam switch 56 detects the product, it activates the positioning vision camera 55 to photograph and inspect the battery pins. The inspection result is compared with the set value to determine whether it is qualified. If the inspection is qualified, a qualified signal is sent, controlling the magnetic switch of the clamping cylinder connected to the positioning claw 53. Upon receiving the instruction, the clamping cylinder operates to clamp and position the battery. After positioning, an instruction is sent to the pneumatic gripper mechanism 41 of the robotic arm 4. The pneumatic gripper mechanism 41 operates to clamp and pick up the positioned battery, which is then transported by the robotic arm 4 to a tray for automatic assembly. If the positioning vision camera 55 detects that the battery pins are unqualified, it sends an unqualified signal. The robotic arm 4 picks up the unqualified battery and transports it to the NG (Not Qualified) tray 6. NG parts are handled manually and enter the rework process.

[0038] Automated assembly: After the product is placed into the designated tray fixture, the battery upper and lower shells and PCB are automatically assembled. After assembly, a visual inspection is performed to determine if the product is qualified. If the product is qualified, it flows into the unloading position through the multi-conveyor line. If the camera determines that the product is unqualified, the robot will put the product into the NG tray 6.

[0039] In the tire pressure sensor battery assembly equipment provided in a specific embodiment of the present invention, a panel, anti-static glass, and safety door 7 are provided on the outer periphery of the frame 1, forming a cabinet structure. A display screen is provided on the panel. A tri-color light 8 is provided above the frame 1, and support legs and casters are provided below the frame 1.

Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this invention.
