Technical Field

[0001] The utility model belongs to the technical field of testing equipment, and particularly relates to a manual pressing test mechanism. Background Art

[0002] In conventional electronic product testing mechanisms, it is common to use a cylinder to push a pressing plate to drive a needle block mold to move into contact with the product to be tested for power-on. Therefore, this testing mechanism needs to rely on a pneumatic system and is more suitable for large-scale, assembly-line production environments. Although this testing mechanism improves the degree of automation, for small-batch testing of small electronic products (such as mobile phone motherboards, tablet computer motherboards, etc.), the preparation cost of the testing mechanism is high and it is not flexible enough. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a manual pressing test mechanism to solve the technical defects described in the background art.

[0004] The manual pressing test mechanism includes a base. The base is provided with a product slot for placing the main board to be tested. One side of the base is pivotally connected with a flip cover that can be covered on the base. The top of the flip cover is supported by a pressing block spring with a pressing block. The pressing block is provided with a guide post passing through the flip cover. The guide post is fixed with a pressing plate located below the flip cover and used to press down on the base. The pressing plate is provided with a needle block module for entering the product slot to contact and power on the main board to be tested.

[0005] According to the above technical solution, the utility model can achieve the following beneficial effects:

[0006] After the main board to be tested is placed in the product slot, first cover the flip cover on the base. After that, only need to manually press the pressing block. The pressing block drives the pressing plate to approach the base, so that the needle block module enters the product slot to contact and power on the main board to be tested for testing. After the test is completed, just stop pressing the pressing block. The pressing block spring pushes the pressing block to rise and reset. The pressing block drives the pressing plate to rise and reset, so that the needle block module moves away from the main board. Therefore, when testing the main board, the utility model can realize driving the needle block module to contact and power on the main board to be tested without relying on cylinders, electric cylinders, lead screw modules or hydraulic modules, etc. For small-batch testing of small electronic products, the utility model can reduce the preparation cost of the testing mechanism. At the same time, the testing mechanism is also convenient to move to various positions for work, thereby improving the flexibility of the testing mechanism.

[0007] In order to further optimize the above technical solution, without conflict, one or more of the following embodiments can be optionally combined.

[0029] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings.

[0030] As Figures 1 to 5 shown, the present specific embodiment provides a manual pressing test mechanism, which includes a base 1 and a needle block module 4. The base 1 is provided with a product slot 11 and a positioning hole 22, and the product slot 11 is used for placing the main board 5 to be tested.

[0031] One side of the base 1 is pivotally connected with a flip cover 2 that can be lowered to cover the base 1. The flip cover 2 is provided with a support post 33 for contacting the upper surface of the base 1. The flip cover 2 is provided with a first buckle 21 and a positioning post 35. After the flip cover 2 is turned down and pressed onto the base 1, the first buckle 21 is used to lock with the base 1, and the positioning post 35 is inserted into the positioning hole 22.

[0032] The top of the flip cover 2 is supported with a lower pressing block 3 through a pressing block spring 36. The lower pressing block 3 is provided with a guide post 31 passing through the flip cover 2, and the guide post 31 can slide within the flip cover 2. The lower pressing block 3 is installed with a second buckle 34. When the lower pressing block 3 is pressed down to a certain height, the second buckle 34 is used to lock with the flip cover 2. A pressing plate 32 is fixed to the guide post 31 and located below the flip cover 2 for pressing down onto the base 1. The pressing plate 32 is provided with an adjustment hole 431.

[0033] The needle block module 4 includes a fixed block 41 and an upper needle block 42; the fixed block 41 is provided with a probe 412, an equal-height screw 432, and a sliding groove 411. The equal-height screw 432 is mounted in the adjustment hole 431 and slides within the adjustment hole 431. A secondary spring 433 is provided between the fixed block 41 and the pressing plate 32. The sliding groove 411 is provided with a hanging platform 413; the upper needle block 42 is provided with a hanging plate 421 that moves up and down and slides within the sliding groove 411. The hanging platform 413 supports the hanging plate 421. The upper needle block 42 is used to press down the main board 5 to be tested. The probe 412 can pass through the upper needle block 42 and enter the product slot 11 to contact and energize the main board 5 to be tested. A primary spring 422 is provided between the upper needle block 42 and the fixed block 41, and the total elastic force of the primary spring 422 is greater than the total elastic force of the secondary spring 433.

[0034] The following is the working process of a manual pressing test mechanism according to this specific embodiment:

[0035] The main board 5 to be tested is placed in the product slot 11. Thereafter, the flip cover 2 is lowered to cover the base 1. At this time, the support post 33 contacts the upper surface of the base 1 to support the flip cover 2, and the flip cover 2 is locked and fixed to the base 1 through the first buckle 21; thereafter, the lower pressing block 3 is pressed down. The lower pressing block 3 drives the pressing plate 32 to approach the base 1. At this time, the main board 5 to be tested then pushes the upper needle block 42 to rise. Since the total elastic force of the primary spring 422 is greater than the total elastic force of the secondary spring 433, the upper needle block 42 drives the entire needle block module 4 to rise, so that the probe 412 is further vertically aligned with the main board 5 to be tested. When the secondary spring 433 is compressed to a certain extent, the needle block module 4 will not rise, and the upper needle block 42 will continue to rise to compress the primary spring 422. At this time, the probe 412 passes through the upper needle block 42 and enters the product slot 11 to contact and energize the main board 5 to be tested; thereafter, the lower pressing block 3 is locked and fixed to the flip cover 2 through the second buckle 34 to maintain the height of the lower pressing block 3 at this moment, so that the needle block module 4 continuously contacts and energizes the main board 5.
