Background

In the production and manufacturing process of the product, a function testing device for the product is indispensable for ensuring the quality of the product. For electronic products, a mechanical structure is often combined with a probe structure for testing at present.

Chinese patent CN211718422U discloses a testing device, comprising a testing board, a first fixing board, a second fixing board and a movable board, which are arranged in parallel in sequence along a first direction, wherein the first fixing board and the second fixing board are arranged at an interval, the movable board can move along the first direction, and one side of the movable board, which is away from the second fixing board, is provided with a containing slot for placing a product to be tested, the testing device further comprises a long probe, one end of the long probe is abutted against the testing board, and the other end of the long probe sequentially passes through the first fixing board and the second fixing board and is inserted into the movable board to test the product to be tested; the second fixed plate is provided with a linear bearing, the movable plate is provided with a guide shaft, and the guide shaft is matched with the linear bearing along a first direction; an elastic member is supported between the movable plate and the second fixed plate, and a limiting member is further disposed between the movable plate and the second fixed plate. The testing device can improve the testing stability through the guide matching of the linear bearing and the guide shaft. Chinese patent CN211235951U discloses a probe protection device and a test apparatus, the probe protection device includes a protection structure provided with a plurality of first through holes; one end of the connecting structure is fixedly connected with the protection structure; the sliding structure is provided with a plurality of second through holes and a plurality of third through holes, the sliding structure is sleeved on the connecting structure through the second through holes, the third through holes are coaxially arranged with the first through holes, and the third through holes are used for probes to pass through; the sliding structure is configured to be axially slidable along the connecting structure, and when the sliding structure is slid to a first position, the connecting needle of the probe in the third through hole can pass through the first through hole. The probe protection device and the test equipment reduce the risk of deformation caused by the fact that the connecting needle head is exposed outside, prolong the service life of the probe and reduce the cost of product test. However, the connection of the components of the testing device is relatively complex, and a certain stability defect also exists in the aspect of matching of a product to be tested and the probe.

Aiming at the problems of complex components, poor stability and the like of a testing mechanism in the prior art, a testing mechanism which is simple in structure and can ensure stable contact between a product to be tested and a probe needs to be found urgently.

Further, the work flow of the compound mechanism comprises the following steps:

(1) the product to be detected is placed into the product positioning block for positioning, the product to be detected is pressed downwards, the product positioning block drives the product to be detected and the fixing blocks to move downwards together under the guiding action of the guide columns (the guiding action is vertical guiding movement), and when the fixing blocks on the two sides are in contact with the wedge block and move according to the preset angle of the wedge block, the fixing blocks on the two sides are simultaneously changed into horizontal opposite movement from the pressing movement direction; the process can realize the function of fixing the product to be measured in a mode of pressing from two sides.

(2) Continuing to press down the product to be detected, and driving the fixed product to be detected to be vertically pressed down by the product positioning block until the product to be detected is completely contacted with the probe module; the process can realize the function of safely and stably contacting the probe module with the product to be detected, avoid the problems of scratching, bruising and the like caused by mistakenly contacting other positions of the product to be detected, and simultaneously protect the probe module from being damaged by the contact of the product to be detected;

(3) the buckle is buckled with the base to realize self-locking action.

The technical effects obtained by the invention are as follows:

1. the invention adopts a simple component mechanism, realizes the progressive execution of two actions (firstly fixing a product, then contacting a probe, and finally realizing self-locking by the fixing mechanism), has simple appearance and convenient installation, debugging and maintenance; the power source of the mechanism is manual, no automatic control part is provided, no external equipment (such as pneumatic, electric and other system accessories) is provided, automatic control is not needed, the number of clamp parts is reduced, and the man-machine operability is convenient and efficient; because the parts are reduced, automatic control is not needed, and the cost is obviously reduced.

2. The product that awaits measuring keeps contact state with the probe module on the base when putting into the test of product locating piece, and anchor clamps mechanism usage is manually operation, makes things convenient for operator safety, quick, accurate getting to put. Before the test begins, can effectively avoid the probe when the product is put into the location test piece, during the test, the product can carry out perpendicular pushing down action at fixed good state and contact the probe, after the product is stable with the probe contact, can realize the auto-lock with this state, maintains the contact of probe and product, guarantees the stability of test.
