[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0026] Please combine Figure 1-3 The utility model discloses a mobile phone test fixture which can be used for mobile phone camera height difference test and pre-push test, reduces the number of material guiding times and the bumps in the material guiding process, reduces labor costs and test time, and improves product yield and test efficiency. The mobile phone test fixture includes a limiting top plate 100, a limiting bottom plate 200 and a pre-push component. The three are assembled to form a fixture that can be used to push the product to be tested and provide an auxiliary tool for measuring the height difference of the product camera. Specifically, the limiting top plate 100 is arrayed with a plurality of plug-in holes 110 penetrating the upper surface and the lower surface of the limiting top plate 100; the limiting bottom plate 200 is located below the limiting top plate 100 and is fixedly connected to the limiting top plate 100, and the upper surface of the limiting bottom plate 200 is provided with a plurality of pre-push positions corresponding to each of the plug-in holes 110; the pre-push assembly includes a plurality of pre-push ejection blocks 300 correspondingly arranged on each of the pre-push positions and correspondingly inserted into the plug-in holes 110, the bottom of the pre-push ejection block 300 is elastically abutted against the upper surface of the limiting bottom plate 200, and the top of the pre-push ejection block 300 protrudes from the upper surface of the limiting top plate 100. Preferably, in this embodiment, the upper array of the limit top plate 100 is provided with 4 rows and 6 columns, totaling 24 plug holes 110. Similarly, the upper surface of the limit bottom plate 200 is provided with 24 pre-push positions, and the pre-push assembly includes 24 pre-push top blocks 300. In this way, when the mobile phone test fixture is assembled, 24 products can be pre-push tested and height difference tested at one time. Of course, in actual production, the number of plug holes 110, pre-push positions and pre-push top blocks 300 can be further adjusted according to the production scale, which will not be repeated here.
[0027] The mobile phone test fixture is provided with a limit top plate 100, a limit bottom plate 200 and a pre-push assembly. After the pre-push top blocks 300 are correspondingly embedded in the plug holes 110 of the limit top plate 100 and the limit bottom plate 200 is fixed to the lower surface of the limit top plate 100, the positioning of each pre-push top block 300 is realized, so that a plurality of products to be tested introduced into the material tray can be placed above the limit top plate 100 at the same time. The pre-push top blocks 300 limit the top position of the products and cooperate with the external pre-push test equipment to realize the pre-push test of the products. After the mobile phone test fixture is assembled, , the upper surfaces of each pre-push ejector block 300 are in the same plane. After the pre-push test, there is no need to remove the product. By cooperating with external infrared or laser height difference testing equipment, the gap between the pre-push ejector block 300 and the product can be measured to detect products with unqualified height difference. In this way, the mobile phone camera height difference test and pre-push test can be realized by loading the product only once, which can shorten the entire test cycle, improve production and testing efficiency, save time and labor costs, and reduce bumps due to the lack of material guiding process in the measurement process, thereby improving the product appearance yield.
[0028] Please combine Figure 1 , Figure 3-5 as well as Figure 7 In one embodiment, an ear hole 120 is provided on the inner side wall of the plug-in hole 110, and the ear hole 120 extends from the lower surface of the limiting top plate 100 to the upper surface and passes through the lower surface of the limiting top plate 100, and the depth of the ear hole 120 is less than the depth of the plug-in hole 110; the ring side surface of the pre-pushing ejection block 300 is provided with a lug 310 that slidably cooperates with the ear hole 120, and the height of the lug 310 is greater than or equal to the depth of the ear hole 120. By providing a lug 310 on the pre-push ejector block 300 and opening an ear hole 120 on the inner wall of the plug-in hole 110, it is possible to achieve guide limitation of the pre-push ejector block 300 when it slides in the plug-in hole 110. At the same time, the depth of the ear hole 120 is limited to be smaller than the depth of the plug-in hole 110. The inner side wall of the ear hole 120 adjacent to the upper surface of the limiting top plate 100 cooperates with the end face of the lug 310 to limit the pre-push ejector block 300, so as to prevent the pre-push ejector block 300 from being separated from the plug-in hole 110 under the elastic push of the limiting bottom plate 200, thereby ensuring the normal progress of the product pre-push test and height difference test operations. Further preferably, two ear holes 120 are relatively provided on the inner wall of the plug-in hole 110, and two lugs 310 are relatively provided on the ring side of the pre-push ejection block 300. In this way, by increasing the matching area between the lugs 310 and the inner wall of the ear hole 120, the stability of the installation of the pre-push ejection block 300 is improved to prevent it from shaking.
[0029] Further integration Figure 3 as well as Figure 6-7In one embodiment, a stepped hole 210 is provided on the pre-push position, which passes through the upper surface and the lower surface of the limiting bottom plate 200. The stepped hole 210 includes a small diameter portion adjacent to the lower surface of the limiting bottom plate 200 and a large diameter portion adjacent to the upper surface of the limiting bottom plate 200. A slot 320 is provided at the bottom of the pre-push ejection block 300. The pre-push assembly also includes a plurality of compression springs 400 corresponding to each pre-push ejection block 300. One end of the compression spring 400 is embedded in the slot 320, and the other end of the compression spring 400 is embedded in the large diameter portion and abuts against the transition portion between the large diameter portion and the small diameter portion. By providing the compression spring 400, on the one hand, the limiting bottom plate 200 provides a pre-tightening force against the pre-pushing top block 300 when the limiting top plate 100 and the limiting bottom plate 200 are assembled, and on the other hand, during the disassembly of the fixture, when the limiting top plate 100 and the limiting bottom plate 200 are in restraint contact, the compression spring 400 resets and pushes the limiting bottom plate 200 away from the limiting top plate 100, thereby reducing the difficulty of separating the limiting bottom plate 200 from the limiting top plate 100. In addition, by providing a stepped hole 210 on the pre-pushing position and providing a slot 320 at the bottom of the predetermined top block, the compression spring 400 can be positioned to prevent the compression spring 400 from sliding or twisting.
[0030] Furthermore, a through hole 330 communicating with the slot 320 is provided at the top of the pre-pushing ejector block 300, and the inner diameter of the through hole 330 is smaller than the inner diameter of the slot 320. By providing the through hole 330 at the top of the pre-pushing ejector block 300, the weight of the pre-pushing ejector block 300 can be reduced, so as to reduce the overall weight and material usage of the fixture, and reduce the processing cost of the fixture. In addition, in the present embodiment, the limiting top plate 100 and the limiting bottom plate 200 are both made of aluminum alloy material to reduce the overall weight of the fixture. Of course, other alloy materials with light weight and high mechanical strength can also be selected. The pre-pushing ejector block 300 is made of pps material or other plastic materials with high hardness.
[0031] Please combine Figure 3-6 In one embodiment, the lower surface of the limiting top plate 100 is a plane, and an annular limiting groove 130 is provided on the lower surface of the limiting top plate 100. The middle of the annular limiting groove 130 forms an operation area, and each plug hole 110 is located in the operation area. The middle of the upper surface of the limiting bottom plate 200 is recessed to form a avoiding groove 220 that matches the concave and convex of the operation area, and an annular convex portion 230 that surrounds the avoiding groove 220 and is embedded in the annular limiting groove 130. The first positioning of the limiting bottom plate 200 and the limiting top plate 100 is achieved by the engagement of the annular convex portion 230 with the annular limiting groove 130. Further, the annular convex portion 230 of the limiting bottom plate 200 is screwed to the limiting top plate 100, and corresponding screw holes are respectively provided on the annular convex portion 230 and the limiting top plate 100, so that the limiting top plate 100 and the limiting bottom plate 200 are screwed to improve the connection strength between the two.
[0032] In one embodiment, the upper surface of the limiting top plate 100 is also provided with at least one pin hole 140 for inserting the plug 500, and the pin hole 140 passes through the bottom surface of the annular limiting groove 130 and is connected to the annular limiting groove. Further preferably, a pin hole 140 is provided at each corner of the limiting top plate 100. By inserting the plug 500 on the limiting top plate 100, the plug 500 provides a positioning part when the fixture cooperates with the external pre-push test equipment and the height difference test equipment, so as to limit the position of the product testing process and improve the reliability of the test results. In addition, in this embodiment, the pin hole 140 is a cylindrical hole, and the plug 500 includes a round rod portion and a frustum portion located at the lower end of the round rod portion. The diameter of the end of the frustum portion is smaller than the diameter of the connection between the frustum portion and the round rod portion. By providing the frustum portion at the bottom of the plug 500, the difficulty of inserting the plug 500 into the pin hole 140 is reduced.
[0033] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
