Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a circuit device translation device for testing. Background Technology

[0002] With the rapid development of electronic technology, the inspection and positioning of circuit components has become a crucial step in modern electronic manufacturing and testing processes. Especially in the manufacturing of high-precision, high-density circuit boards, the ability to quickly and accurately inspect and position circuit components directly impacts product quality and production efficiency. During circuit component inspection, since the components are located on the circuit board, a translation device is needed to fix the board and move it to the inspection station of the testing equipment. However, existing translation devices typically fix the board by pressing, which can damage some components due to the large number of components on the board surface, and can also obstruct other components, thus affecting subsequent inspection operations. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Circuit devices are the basic components or modules that make up electronic circuits. They achieve the functions of the circuit through specific electrical characteristics. Circuit devices can be divided into two main categories: active devices and passive devices, and are widely used in electronic equipment, communication systems, computer hardware, and other fields.

[0023] Due to the inherent technical limitations of existing technologies, such as poor fixation effects, please refer to... Figures 1-4 This utility model provides a circuit device translation device for testing. A drive unit 901 operates, causing a side clamping unit 903 to move. The grippers 9035 on the side clamping unit 903 can clamp and fix the circuit board from the side, ensuring a secure fixation and preventing damage to the circuit devices or obstruction during testing. The device includes a fixed plate 1, on which a linear screw module 1 2 is mounted. A movable plate 3 is fixed to the linear screw module 1 2, and a linear screw module 2 5 is mounted on the movable plate 3. A mounting block 6 is fixed to the linear screw module 2 5, and a testing platform 7 is fixed to the mounting block 6. A fixing component 9 is fixed to the bottom of the testing platform 7 and attached to the mounting block 6. The circuit board is placed on the testing platform 7, and then the drive unit 901 operates, causing the side clamping unit 903 to move. The grippers 9035 on the side clamping unit 903 clamp and fix the circuit board from the side. After fixing, the testing platform 7 moves to the testing station of the testing equipment as the linear screw modules 1 2 and 2 5 move.

[0024] Existing translation devices typically use a pressing method to fix circuit boards. This has two drawbacks: firstly, the circuit board surface contains many circuit components, making some susceptible to damage; secondly, it can obstruct some components, thus affecting subsequent testing operations. To address this issue, please refer to... Figure 2 and Figure 3 The fixing component 9 consists of a drive unit 901, an adjustment unit 902, and a side clamping unit 903. The drive unit 901 is fixed to the inside of the mounting block 6. There are two adjustment units 902, which are respectively fixed to both ends of the drive unit 901. Two side clamping units 903 are fixed on the adjustment unit 902 and slidably mounted on the testing table 7. The drive unit 901 is responsible for providing power and moving the side clamping units 903, thereby clamping and releasing the circuit board. The adjustment unit 902 can adjust the distance between the two grippers 9035, so that it can also fix circuit boards of different sizes.

[0025] Furthermore, to ensure greater stability of the moving plate 3 and the testing table 7 during horizontal movement, two sets of guide rails 1 4 are installed on the fixed plate 1. Both sets of guide rails 1 4 are slidably connected to the bottom of the moving plate 3. Similarly, two sets of guide rails 2 8 are installed on the moving plate 3. Both sets of guide rails 2 8 are slidably connected to the bottom of the testing table 7. The guide rails 1 4 and guide rails 2 8 guide the moving plate 3 and the testing table 7, making their movement more stable.

[0026] When using a side clamp to secure a circuit board, it needs to be clamped from both sides, requiring at least four clamping points. The challenge lies in controlling the synchronous operation of the four 9035 grippers to achieve the desired clamping action. For this purpose, please refer to... Figure 3 The drive unit 901 includes a slide rail 9011 fixedly connected to the inner side of the mounting block 6. A stepper motor 9012 is installed at one end of the slide rail 9011. The output shaft of the stepper motor 9012 is fixedly connected to one end of a bidirectional lead screw 9013. The bidirectional lead screw 9013 is rotatably connected inside the slide rail 9011. Both ends of the bidirectional lead screw 9013 are helically connected to lead screw sliders 9014. When the stepper motor 9012 works, it can drive the bidirectional lead screw 9013 to rotate. Since the threads at both ends of the bidirectional lead screw 9013 are in opposite directions, it drives the gripper 9035 units on both sides to rotate synchronously to achieve clamping of the circuit board.

[0027] Because different circuit boards have different sizes, if the two 9035 grippers on the same side have the same spacing, the number of compatible circuit board models is limited, resulting in poor compatibility. Therefore, please refer to... Figure 3 and Figure 4The adjustment unit 902 includes a connecting plate 9021 fixed to the lead screw slider 9014. A bidirectional screw 9022 is rotatably connected to the inner side of the connecting plate 9021. Both ends of the bidirectional screw 9022 are helically connected to the screw slider 9023. By rotating the bidirectional screw 9022 and driving the screw slider 9023 to move, since the threads at both ends of the bidirectional screw 9022 are opposite, the two gripper 9035 units on the same side can be brought closer or further apart to adjust the spacing between the grippers 9035. This makes it suitable for clamping and fixing circuit boards of different sizes.

[0028] To achieve side clamping of the circuit board, please refer to... Figure 3 and Figure 4 The side clamping unit 903 includes a toothed plate 9031 fixedly connected to the screw slider 9023. A gear 9032 meshes with one side of the toothed plate 9031. The gear 9032 is fixedly mounted on a rotating shaft 9033. The bottom of the rotating shaft 9033 is rotatably connected to a connecting block 9034. One end of the connecting block 9034 is slidably disposed in a groove opened at the bottom of the toothed plate 9031. The top of the rotating shaft 9033 passes through a strip-shaped hole opened on the surface of the detection table 7 and is fixedly mounted with a gripper 9035. A rubber pad 9036 is fixed on the outer wall; when the drive unit 901 drives the adjustment unit 902 to move, the adjustment unit 902 drives the toothed plate 9031 to move, the toothed plate 9031 drives the gear 9032 to rotate, and the gear 9032 drives the gripper 9035 to rotate through the rotating shaft 9033. Since the two grippers 9035 on the same side rotate in opposite directions, the two grippers 9035 on the same side can approach the circuit board and clamp it. The movement principle of the two grippers 9035 on the other side is the same as above.
