Description

Technical Field

[0001] This utility model relates to the field of FPC testing technology, and in particular to a convenient adjustment needle module for automotive battery FPC testing. Background Technology

[0002] FPC (Flexible Printed Circuit) is also known as a flexible circuit board or flexographic circuit board. It is a highly reliable and flexible printed circuit board made of polyimide or polyester film as the substrate. It features high wiring density, light weight, thinness, and good bending performance. In the field of automotive battery production line technology, automotive batteries are composed of six electrode groups welded together. Poor welding of the solder joints between the electrode groups often leads to open circuits inside the automotive battery, resulting in an increased scrap rate. Therefore, after the electrode groups of the automotive battery are welded, it is necessary to test the resistance value, insulation withstand voltage, and bonding strength of the aluminum sheet and tweezers welded together to ensure the robustness of the battery pack welding.

[0003] However, in China, the quality inspection of FPCs still mainly relies on manual visual inspection, which is costly and inefficient. With the rapid development of the electronics industry, circuit board design is becoming increasingly high-precision and high-density, and traditional manual inspection methods can no longer meet production needs. Automated inspection of FPC defects has become an inevitable trend in the industry's development.

[0004] In the use of existing FPC automated testing devices, a single set of needle mold components is typically moved one by one to test the entire group of automotive products (such as Chinese utility model patent application number CN202311793481.1). When the automotive batteries assembled by the factory to meet production requirements are large, the above-mentioned testing efficiency is very low, and the adjustment flexibility of the needle mold components is also low. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The lowering component 7 and the conveying component 4 are respectively equipped with a barcode scanner component 16 and a product socket connection component 10 at their inlet and outlet ends. The barcode scanner component 16 is supported and connected to the machine base 1 by a mounting plate 12. An X-axis module 18 for movement is installed between the bottom of the mounting plate 12, the bottom of the product socket connection component 10 and the machine base 1. The product socket connection component 10 includes a mounting frame 1004. A horizontal plate 1001 and a connector 1002 are installed on the mounting frame 1004. A lifting component 1003 for lifting is installed between the horizontal plate 1001 and the mounting frame 1004.

[0034] Specifically, the connector 1002 uses a pneumatic telescopic cylinder that moves in the X-axis direction (the air source device connected to the pneumatic telescopic cylinder is an independent air source device, and the specific structure can be easily implemented by those skilled in the art based on relevant technologies). Its telescopic end is provided with a connecting fixture that connects to the product socket. The other end of the connecting fixture is connected to the circuit of the testing instrument 17 via a signal line, which facilitates the insertion of the connecting fixture into the product socket by pushing it with the pneumatic telescopic cylinder, so that the testing instrument 17 is connected to the product socket circuit. The X-axis module 18 at the bottom of the product socket connecting assembly 10 facilitates the movement of the product socket connecting assembly 10 towards the product according to the product width, thereby facilitating the operation of inserting the connecting fixture into the product socket by the pneumatic telescopic cylinder. The lifting member 1003 uses a pneumatic telescopic cylinder that moves in the Y-axis direction, which can perform circuit connection work for product sockets set at different heights.

[0035] By adopting the above technical solution, and through the setting of the needle bed assembly 5 and the needle bed spacing adjustment assembly 9, the resistance value and insulation withstand voltage test of the solder joints of the entire product can be performed simultaneously. After the conveying assembly 4 conveys the tooling plate loaded with the product into place, the positioning assembly 11 performs the positioning operation of the product, thereby facilitating the high accuracy of the alignment connection between the needle bed assembly 5 and the product, which can improve the accuracy and efficiency of the test and ensure that the test signal can be effectively transmitted. Through the cooperation of the individually adjustable needle mold 502 on the needle bed assembly 5 and the needle bed spacing adjustment assembly 9 that can adjust the position of the aluminum and nickel sheets on the complete set of automotive batteries of different specifications and sizes produced and assembled according to the requirements of the application, the spacing of the array of needle mold 502 and the array of needle bed assemblies 5 can be adjusted individually, so that this device can be used for resistance value and insulation withstand voltage test of different types of complete sets of automotive battery packs, which is conducive to improving the applicability and flexibility of the equipment.

[0039] Furthermore, when the positioning platform 1102 moves up and down in conjunction with the lifting cylinder 1106, the stability of the lifting and lowering of the positioning platform 1102 can be improved through the cooperation of the guide cylinder 1103 and the guide rod 1107.

[0040] The needle bed assembly 5 includes a connecting rod 501 mounted on the needle bed spacing adjustment assembly 9. The connecting rod 501 is equipped with an array of needle molds 502 for detecting products. The needle molds 502 and the connecting rod 501 are supported and connected by a movable frame 503.

[0041] Furthermore, the connector at the end of the needle mold 502 is connected to the needle mold socket 506 and the plug component 505 via a signal line to the test instrument 17 to provide resistance and insulation withstand voltage tests for the product. The lower end of the connector of the needle mold 502 is connected to a probe, which conducts the product to the test instrument 17 to detect the resistance and insulation withstand voltage of the solder joints of the aluminum and nickel sheets on the automotive battery pack, ensuring the firmness and safety of the battery pack welding.

A needle mold fixing part 504 for locking the movement of the needle mold X-axis is provided between the movable frame 503 and the connecting rod 501. An array of needle mold sockets 506 for connecting signal lines is installed on the connecting rod 501. A plug part 505 for integrating the interface is provided at one end of the connecting rod 501.

[0043] Furthermore, the connecting rods 501 are distributed in an array, and the connecting rods 501 are connected to the needle bed spacing adjustment component 9 through a sliding component, which facilitates the adjustment of the spacing between the needle bed components 5.

[0044] The needle bed spacing adjustment assembly 9 includes a protrusion 901 installed on the side plate 8. Both ends of the protrusion 901 are detachably installed with baffles 902. Both the upper and lower ends of the protrusion 901 are provided with sliding parts 903. Sliding plates 904 are slidably connected to the sliding parts 903.

The disassembly and setting of the baffle 902 makes it easy to increase or decrease the corresponding number of needle bed assemblies 5 according to the number of welding points of the products being assembled, which helps to improve the applicability and flexibility of the equipment.

[0046] The barcode scanner component 16 is externally equipped with a connecting frame 15. A position adjustment component 14 for moving the X-axis is installed between the connecting frame 15 and the mounting plate 12. A position sensor 13 is provided below the position adjustment component 14 and is connected to the conveying component 4.

[0047] Furthermore, the movement of the X-axis module 18 located at the bottom of the mounting plate 12 drives the barcode scanner component 16 on the mounting plate 12 to move along the X-axis of the equipment and enter the product's positioning area. In conjunction with the position adjustment component 14 connected to the barcode scanner component 16, the barcode scanner component 16 moves along the Z-axis of the equipment to perform individual barcode scanning on each product and record the product code coordinates. The position sensor 13 detects the position of the tooling plate on which the product is loaded and sends the position signal to the PLC controller (PLC stands for Programmable Logic Controller), enabling the PLC controller to perform the next program operation according to the corresponding control instructions.

[0048] The conveying assembly 4 includes a conveying frame 403, with sprockets 401 on both sides of the conveying frame 403. A drive component 402 for driving is installed at one end of the conveying frame 403, and a chain is installed on the sprockets 401 for conveying the tooling plate loaded with the product.

[0049] Furthermore, the drive component 402 adopts a servo stepper motor. The servo component motor is distributed in two groups, and the drive sprocket 401 cooperates with the chain drive to transport the tooling plate loaded with the product.

[0050] The machine 1 also includes a safety cover 2, which is equipped with a movable door 3 for flipping open, and a testing instrument 17 is suspended on the inner wall of the safety cover 2.

[0051] Furthermore, a PLC controller (the structure of the PLC controller is the same as or implemented using existing technology, and will not be described in detail here, and is not shown in the attached figure) is installed on the outside of the safety cover 2 to control the various electrical components inside the device. Product inlets and outlets are opened at both ends of the safety cover 2 to facilitate the entry of tooling plates loaded with products into the equipment for testing. The movable door 3 is designed to open by flipping it open, which makes the space above the needle bed assembly 5 large, making it convenient for workers to adjust the spacing of the needle bed assembly 5 and / or adjust the array needle module 502 individually, which has high practicality.

[0052] Working principle: First, the tooling plate containing the entire set of automotive batteries is conveyed to the positioning component 11 inside the equipment via the conveying component 4. The positioning platforms 1102 of the two positioning components 11, in conjunction with the lifting cylinder 1106, rise simultaneously, causing the positioning pins 1104 on the positioning platform 1102 to engage with the positioning sleeves on the tooling plate (the specific structure of the tooling plate holding the entire set of automotive battery products and the positioning sleeves can be implemented using existing technology and will not be elaborated here). After completing the positioning operation of the product tooling plate, the X-axis module 18 set at the bottom of the mounting plate 12 moves, driving the barcode scanner component 16 on the mounting plate 12 along the X-axis of the equipment. The device moves towards the product's positioning area and works in conjunction with the position adjustment component 14 connected to the barcode scanner component 16. This causes the barcode scanner component 16 to move along the Z-axis of the device, performing individual barcode scanning on each product and recording the product code coordinates. Furthermore, the X-axis module 18 at the bottom of the product socket connection component 10 moves, causing the connector 1002 to connect to the product socket. Then, the Y-axis module drives the needle bed assembly 5 to move downwards, causing the probes on the array of needle modules 502 on the needle bed assembly 5 to press against the solder joints of the aluminum and nickel sheets on the product for resistance and insulation withstand voltage testing, ensuring the strength and safety of the product solder joints.
