Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit boards, in particular to a test clamping device for integrated circuit boards. Background Technique

[0002] An integrated circuit board is a carrier for mounting integrated circuits. However, when referring to an integrated circuit board, the integrated circuit is often also included. The integrated circuit board is mainly composed of silica gel, so it is generally green. The electronic components of the integrated circuit board are welded by a soldering gun and solder.

[0003] For example, a clamping device for testing an integrated circuit board disclosed in the Chinese Patent Publication No. "CN218298333U" in the prior art includes a detection table. Two sliding holes are opened at the upper end of the detection table. A detection equipment main body is installed at the front end of the detection table. Two clamping plates are arranged on the detection table. A clamping mechanism is arranged at the bottom of the detection table. The clamping mechanism is connected to the two clamping plates to fix the integrated circuit board. When turning the turning handle, it is necessary to turn slowly to prevent the two clamping plates from moving too fast and squeezing and damaging the integrated circuit board. In the utility model, the threaded cooperation of the bidirectional lead screw and the fixed plate drives the clamping plate to move, and the integrated circuit board is clamped and fixed by the movement of the two clamping plates, and the convenience of detecting the integrated circuit board is optimized by stably clamping the integrated circuit board.

[0004] Although this embodiment can ensure the stable clamping of the integrated circuit board, it adopts the direct contact method of the flat clamping plate. However, in the actual operation process, the integrated circuit board may be inclined. If the flat clamping plate directly clamps it at this time, it may cause damage to the integrated circuit board. Although it can be corrected manually, this method is not only time-consuming but also has low efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art, and to propose a test clamping device for integrated circuit boards.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a test clamping device for an integrated circuit board, including a detection table. A driving device is fixedly connected to the lower end of the detection table. Four channels are provided on the detection table. A clamping component is slidably connected in each of the four channels. The driving device is used to drive the clamping component to move;

[0008] Wherein, the clamping component includes a sliding part and a clamping part. A reset component is arranged between the sliding part and the clamping part. The reset component is used to reset the clamping part on the clamping component. A locking component is arranged on the sliding part. The locking component is used to limit the clamping component.

[0009] Further, the driving device includes a motor, the motor is fixedly connected to the lower end of the inspection table, and a gear is fixedly connected to the end of the motor shaft.

Plate bodies are fixedly connected to the middle parts of the two guide frames. Rack bars are fixedly connected to both of the plate bodies. The rack bars are meshed with the gear, and the rack bars penetrate through the other plate body.

[0011] Further, the sliding member includes a sliding block slidably connected in the channel. A round shaft is rotatably connected to the lower end of the sliding block, and the round shaft is rotatably connected in the groove of the guide frame. The reset assembly is fixedly connected to the upper end of the sliding block;

[0012] The clamping member includes an L-shaped plate rotatably connected to the reset assembly. Wheel members are rotatably connected to the lower sides of both ends of the L-shaped plate.

[0013] Further, the reset assembly includes a housing fixedly connected to the sliding block. A spring is fixedly connected inside the housing, and the other end of the spring is fixedly connected to the lower side of the L-shaped plate.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 , an integrated circuit board test clamping device includes a detection table 1, a driving device 2 is fixedly connected to the lower end of the detection table 1, four channels 11 are provided on the detection table 1, and a clamping assembly 3 is slidably connected in each of the four channels 11. The driving device 2 is used to drive the clamping assembly 3 to move;

[0023] Among them, the clamping assembly 3 includes a sliding member 31 and a clamping member 32. A reset assembly 4 is provided between the sliding member 31 and the clamping member 32. The reset assembly 4 is used to reset the clamping member 32 on the clamping assembly 3. A locking assembly 5 is provided on the sliding member 31. The locking assembly 5 is used to limit the clamping assembly 3. Among them, a placement table for placing an integrated circuit board is provided at the center position of the detection table 1.

[0024] It should be noted that the driving device 2 includes a motor 21. The motor 21 is fixedly connected to the lower end of the detection table 1. A gear 22 is fixedly connected to the shaft end of the motor 21. When the motor 21 rotates, it drives the gear 22 to rotate, and the rotation of the gear 22 drives the rack 26 to translate.

[0025] Among them, the driving device 2 further includes two guiding frames 23 which are arranged oppositely. Both lower ends of each guiding frame 23 are fixedly connected with a plate 24. Two guide rods 12 are fixedly connected between the lower legs of the inspection table 1. The plate 24 is slidably connected with the guide rod 12. A plate body 25 is fixedly connected to the middle of each of the two guiding frames 23. A rack 26 is fixedly connected to each of the two plate bodies 25. The rack 26 meshes with the gear 22. The rack 26 penetrates through the other plate body 25. The guiding frame 23 is fixedly connected with the plate 24, and the plate 24 is slidably connected to the guide rod 12. In this way, the guiding frame can only move translationally along with the guide rod 12. However, the plate body 25 is fixedly connected to the guiding frame 23. Therefore, the plate body 25 can also only move translationally. One end of the rack 26 is fixedly connected to the plate body 25 and penetrates through the other oppositely arranged plate body 25. Therefore, the rack 26 will also only move translationally.

[0026] On the basis of the above embodiment, the sliding member 31 includes a sliding block 311 slidably connected in the channel 11. A round shaft 312 is rotatably connected to the lower end of the sliding block 311. The round shaft 312 is rotatably connected in the groove of the guiding frame 23. A reset assembly 4 is fixedly connected to the upper end of the sliding block 311.

[0027] The clamping member 32 includes an L-shaped plate 33 rotatably connected to the reset assembly 4. Wheel members 34 are rotatably connected to the lower sides of both ends of the L-shaped plate 33. In the present utility model, a housing is further sleeved outside the wheel member 34. The material of the housing includes, but is not limited to, elastic materials such as rubber.

[0028] Among them, the reset assembly 4 includes a housing 41 fixedly connected to the sliding block 311. A hairspring 42 is fixedly connected inside the housing 41. The other end of the hairspring 42 is fixedly connected to the lower side of the L-shaped plate 33.

[0029] In this embodiment, the locking assembly 5 includes a locking block 52. An opening for accommodating the locking block 52 is formed on the sliding block 311. The locking block 52 is slidably connected to the opening of the sliding block 311. A spring 51 is fixedly connected between the locking block 52 and the sliding block 311. Among them, the locking block 52 is located below the inspection table 1 and is used to fix the locking block 52. After pressing the locking block 52, the clamping assembly 3 can be taken out of the inspection table 1 for easy replacement.

[0030] Working method: During the operation, the integrated circuit board is first placed on a special placement table, and then the motor 21 is started. The rotation of the motor 21 drives the gear 22, drives the movement of the rack 26, and thus drives the guide frame 23 to move it. With the displacement of the guide frame 23, the circular shaft 312 in the guide frame 23 begins to rotate, and drives the sliding block 311 to slide in the groove 11. When the inner wheel 34 lightly touches the integrated circuit board, the wheel 34 and the L-shaped plate 33 rotate synchronously to achieve force dispersion. Through the rotation of the L-shaped plate 33, the outer wheel 34 is also driven to contact the integrated circuit board, and the clamping and straightening actions are completed together. After the detection work is completed, the motor 21 reverses, drives the clamping assembly 3 to move outward, releases the integrated circuit board, and then, the reset assembly 4 resets the L-shaped plate 33 to the initial state, and prepares for the straightening and clamping operation of the next integrated circuit board.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
