[0042] As Figures 1 to 5 The product testing device of the embodiments of the present application, as shown in the drawings, comprises a product positioning seat 13 for placing a product to be tested (referred to as product 11, the same below) and a probe testing module for testing the product to be tested; wherein the probe testing module comprises a probe pressing block 4 (i.e. the upper pressing block shown in the drawings), a test probe 2 arranged in the probe pressing block 4 and a demolding module 10 embedded in the interior of the probe pressing block 4, the probe pressing block 4 can drive the demolding module 10 to elastically contact the product positioning seat 13, and after the contact is in place, the test probe 2 is used to contact test the product to be tested, and when the probe pressing block 4 drives the test probe 2 to move upwards, the demolding module 10 can be used to demold the product 11 after the test is completed, the movement of the probe can lift the product 11, thereby preventing the product from falling during testing.
[0043] Wherein, the shaft hole is arranged in the center of the probe pressing block 4, and the floating guide shaft 14 is arranged in the shaft hole; wherein, the lower end of the floating guide shaft 14 is fixedly connected with the demolding module 10 through the screw 12, and the limiting step 1 is arranged at the upper end of the floating guide shaft 14, the probe pressing block 4 is limited to move between the demolding module 10 and the limiting step 1, in other words, the probe pressing block 4 can drive the demolding module 10 to move up and down, at the same time, the demolding module 10 can also change the position with the probe pressing block 4 under the action of the floating guide shaft 14, so as to realize the effect of pressing test and lifting demolding.
[0044] Specifically, the sliding sleeve 3 and the sliding sleeve outer seat 5 located outside the sliding sleeve 3 can be arranged in the shaft hole, and the floating guide shaft 14 is limited in the sliding sleeve 3 and the sliding sleeve outer seat 5, in order to ensure the movement accuracy and the elastic demolding effect of the demolding module 10 and the probe pressing block 4, at least one guide hole and a spring containing groove coaxially arranged with the guide hole can also be arranged on the probe pressing block 4; wherein, the guide column 7 is arranged in the guide hole, and the spring 8 is sleeved outside the guide column 7, the lower end of the guide column 7 is fixedly connected with the demolding module 10 through the screw 15, and the spring 8 is limited in the demolding module 10 and the spring containing groove.
[0045] However, the containing groove is arranged on the lower surface of the probe pressing block 4, the demolding module 10 is limited to move in the containing groove, and when the upper surface of the demolding module 10 is attached to the lower surface of the probe pressing block 4, the spring 8 is in a compressed state in the spring containing groove, so that when the probe pressing block 4 drives the test probe 2 to move up, the demolding module 10 can continue to limit the product 11 under the action of the spring 8.
[0046] In addition, the probe fixing hole 6 is arranged on the probe pressing block 4, and the test probe is fixed in the probe fixing hole 6, the probe hole corresponding to the position of the test probe is arranged on the demolding module 10, when the demolding module 10 extrudes the spring 8 to be attached to the probe pressing block 4, the test probe 2 passes through the probe hole to be connected with the product to be tested, and the setting position and the number of the probe hole correspond to the position and the number of the test probe 2 and the product to be tested.
[0047] During the test, first, the probe pressing block 4 drives the demolding module 10 to move downwards until the demolding module 10 contacts with the product positioning seat 13, at this time, the test probe 2 does not contact with the product, the probe pressing block 4 continues to move downwards, since the position of the demolding module 10 does not change any more, the probe pressing block 4 will extrude the spring 8 and drive the test probe 2 to move downwards in the probe hole until the probe pressing block 4 and the product positioning seat reach the specified limit position, at this time, the test probe 2 contacts with the product and is conducted, and the test process is completed. When the probe pressing block 4 drives the probe to withdraw, due to the action of the spring 8, the demolding module 10 will not move upwards with the probe pressing block 4, the test probe 2 moves upwards out of the probe hole, due to the limiting action of the pressing module to the product, the test probe 2 directly separates from the product, and the product is still in the product positioning seat 13, so that the product is prevented from being lifted or falling. Further, after the spring 8 is in the natural state, the probe pressing block 4 can drive the demolding module 10 to separate from the product positioning seat 13, so that the test of all products on the product positioning seat 13 is completed at one time.
[0048] In one specific embodiment of the utility model, annular protrusions are arranged at positions of the demolding module 10 corresponding to the probe holes, the size of the annular protrusions is smaller than the size of the product, so that the annular protrusions can limit the product, that is, the annular protrusions can press and limit the product to be tested when the test probe 2 separates from the product to be tested.
[0049] In addition, a first limiting part can be arranged on the probe pressing block 4, and a second limiting part is arranged on the product positioning seat 13, when the probe pressing block 4 drives the test probe 2 to move, the probe pressing block 4 and the product positioning seat 13 can be limited by the first limiting part and the second limiting part, so that the test probe 2 can contact and test the product. It can be known that, in order to prevent the demolding module 10 from hard collision with the product positioning seat 13 or the probe pressing block 4, upper and lower buffer rubber pads 91 and 92 can be arranged on both sides of the demolding module 10, and through holes corresponding to positions of the product to be tested are arranged on the upper and lower buffer rubber pads 91 and 92, so that the demolding module 10 can avoid the test probe 2 and ensure elastic contact between the demolding module 10 and the product positioning seat 13 and the probe pressing block 4.
[0050] It should be noted that the test probes 2 can be arranged uniformly or regularly on the probe pressing block 4, the distribution of the test probes 2 is consistent with the product to be tested on the product positioning seat 13, the number of the test probes and the product to be tested shown in the drawings is 40, and the shape of the probe pressing block 4 and the distribution of the test probes thereon can be flexibly arranged according to the product to be tested and requirements.
[0051] It can be known by the above embodiment that the product testing device can drive the test probe to move and drive the demolding module to move at the same time through the probe pressing block, so that the demolding module and the product positioning seat are in elastic contact, after the test probe tests the product to be tested, when the probe pressing block drives the test probe to move upward, the demolding module can limit and demold the product after testing due to the action of the spring, so that the product is prevented from being lifted by the test probe, the problem that the product falls due to adhesion between the probe and the product during product testing is solved, and the problems of product testing efficiency, qualified rate and the like are affected.
