Description

Technical Field

[0001] This utility model is applied to the technical field of 3C testing, and in particular relates to a multi-acupoint linkage lateral push-semen positioning device. Background Technology

[0002] With the widespread use of smartphones, consumers have increasingly higher requirements for cameras, and the size of camera modules is getting smaller and smaller. A series of tests are carried out during the assembly of mobile phone cameras, and the impedance test of the camera is one of the test items. At present, most camera modules are encased in a shell after assembly, and the PAD points that need to be needled for testing are usually at the top and bottom. During testing, it is necessary to meet the two requirements of easy picking and placing and precise positioning. Easy picking and placing means that there is a certain gap between the acupoints of the product, while precise positioning means that the gap between the acupoints of the product should be as small as possible. These two requirements are usually conflicting, so the solution on the market is usually to design a movable side-push fixture. The fixture is opened when picking up and placing materials, and the fixture is pushed and clamped during testing.

[0003] Currently, to enhance positioning accuracy, positioning fixtures typically employ a combination of acupoint contouring and elastic clamping. This positioning method is highly adaptable, with a small gap between the fixture and the acupoint contouring, resulting in good positioning performance. However, most existing positioning fixture elastic clamping mechanisms can only achieve one power source corresponding to one direction of lateral push. When multiple directions of lateral push clamping are required, designing multiple power sources will increase the size of the lateral push fixture and occupy more space.

[0004] For example, Chinese patent CN216940278U discloses a multi-station side-push positioning device, which includes a fixed base. One side of the fixed base has a groove for a guide bar to move, and the other side of the fixed base has several through slots extending into the groove. Positioning slots are respectively provided beside each of the through slots, and a through guide slot is provided between the through slots and the positioning slots. The guide bar is driven by a cylinder, and several positioning blocks matching the number of through slots are fixed on the guide bar. The positioning blocks pass through the through slots and are connected to a pressure bar, which is positioned within the guide slot with one end facing the positioning slot. The width of the positioning block is smaller than the width of the through slot. This side-push positioning device can solve the positioning needs in a single direction, but it does not yet solve the needs for multi-directional positioning.

[0005] Existing side-push positioning devices cannot achieve coordinated side-push in both the X and Y directions. Given the compact and precise nature of the camera module itself, side-push positioning in only one direction cannot meet its high-precision and high-stability testing requirements. Furthermore, existing side-push modules are large in size. High-precision testing typically requires a compact and streamlined test bench structure, and the size of the test bench is also an important indicator. Existing side-push positioning devices have low structural accuracy. In existing devices, a cylinder drives a side-push rod during side-push, which simultaneously contacts multiple products being pushed. When product 1 is large, the side-push rod will contact product 1, leaving a gap between the side-push rod and product 2. The accuracy of this side-push structure is limited by the consistency of the products, which is unacceptable in high-precision testing. Therefore, it is necessary to provide a multi-aperture coordinated side-push precision positioning fixture that is compact, has high movement accuracy, reduces power input, and achieves coordinated side-push in both the X and Y axes. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-acupoint linkage lateral push precision positioning fixture with compact structure, high movement accuracy, reduced power input, and linkage lateral push in the X-axis and Y-axis directions.

[0007] The technical solution adopted by this utility model is as follows: This utility model includes a base, with the length of the base as the X-axis and the width of the base as the Y-axis. The base is provided with several positioning platforms. A side-push module is provided on the base. The side-push module includes an X-axis push rod. The X-axis push rod is provided with several guide bearings and several X-axis positioning blocks. One end of the X-axis push rod is provided with a connector for connecting to an external drive mechanism. The other end of the X-axis push rod is engaged with the base support through a first compression spring. Several Y-axis push rods are provided above the X-axis push rod. One end of the Y-axis push rod is provided with a Y-axis positioning block. The other end of the Y-axis push rod is engaged with the base support through a second compression spring. The Y-axis push rod has a beveled groove. The guide bearing is engaged with the beveled groove to guide and drive the X-axis push rod and the Y-axis push rod to work together. The X-axis positioning block and the Y-axis positioning block are both positioned and engaged with the positioning platform.

[0008] As can be seen from the above solution, the structure of this application is relatively compact, reducing structural redundancy. When the side-pushing module is applied to an automated testing machine, it can also reduce the load on the automated machine and simplify unnecessary support or fixing structures. A power source drives the X-axis push rod, which in turn drives several Y-axis push rods. Each Y-axis push rod has an individual spring, and each Y-axis push rod can clamp the product individually in the Y direction, improving the clamping accuracy in the Y direction. At the same time, it has linkage side pushing in the X and Y directions, resulting in high movement accuracy, reduced power input, and linkage side pushing in the X and Y directions, thus meeting the testing requirements of the camera module.

[0009] A preferred embodiment is that the upper surface of the X-axis push rod is provided with a first bearing.

[0010] A preferred embodiment is that the upper surface of the Y-axis push rod is provided with a second bearing.

[0011] In a preferred embodiment, the X-axis push rod includes several sets of T-shaped structures arranged side by side. The T-shaped structure includes a horizontal part and a vertical part. The first compression spring is disposed at the end of the horizontal part, the connecting member is disposed at the bottom of the horizontal part, and the X-axis positioning block is disposed on the side of the vertical part.

[0012] In a preferred embodiment, the Y-axis push rod is slidably disposed above the groove of the adjacent T-shaped structure.

[0013] A preferred embodiment is that the base has a mounting groove that is compatible with the X-axis push rod and the Y-axis push rod.

[0014] A preferred embodiment is that the base is provided with a positioning guide sleeve. Attached Figure Description

[0020] like Figures 1 to 5As shown, in this embodiment, the present invention includes a base 1, with the length of the base 1 as the X-axis and the width of the base 1 as the Y-axis. The base 1 is provided with several positioning platforms 2, and a side-push module 3 is provided on the base 1. The side-push module 3 includes an X-axis push rod 4, which is provided with several guide bearings 5 ​​and several X-axis positioning blocks 6. One end of the X-axis push rod 4 is provided with a connector 7 for connection to an external drive mechanism, and the other end of the X-axis push rod 4 is connected to the external drive mechanism via a first compression spring 8. The base 1 provides support, and several Y-axis push rods 9 are arranged above the X-axis push rod 4. One end of each Y-axis push rod 9 is provided with a Y-axis positioning block 10, and the other end of each Y-axis push rod 9 is supported by the base 1 through a second compression spring 11. Each Y-axis push rod 9 has a beveled groove 13, and the guide bearing 5 guides and engages with the beveled groove 13, thereby driving the X-axis push rod 4 and the Y-axis push rod 9 to work together. Both the X-axis positioning block 6 and the Y-axis positioning block 10 are positioned and engaged with the positioning platform 2.

[0021] The positioning platform 2 is used to place the product. The external drive mechanism includes a cylinder and a drive motor, which provides power to the side-push module 3 for opening and closing. The first compression spring 8 is mounted on the X-axis push rod 4, and the first compression spring 8 can provide power to the X-axis push rod 4 to clamp the product in the X direction. The Y-axis push rod 9 is equipped with a second compression spring 11, and the second compression spring 11 can provide a clamping force for each Y-axis push rod 9 to side-push and clamp the product in the Y direction.

[0022] When the side-push module 3 needs to be opened, the external drive mechanism drives the connector 7 to move, causing the X-axis push rod 4 to move towards the first compression spring 8. At this time, the guide bearing 5 moves synchronously with the X-axis push rod 4, and the guide bearing 5 contacts the inclined groove 13. The inclined groove 13 has an angular deviation from the Y direction, thereby causing the Y-axis push rod 9 to open towards the second compression spring 11, achieving the linkage side-push function. At this time, the side-push module 3 in both the X and Y directions is open, and several products can be picked up and put in. When the side-push module 3 needs to clamp products, as long as the power input of the external drive mechanism stops, the X-axis push rod 4 and the Y-axis push rod 9 will clamp the products under the elastic force of the first compression spring 8 and the second compression spring 11.

[0023] like Figure 2 As shown, in this embodiment, a first bearing 14 is provided on the upper surface of the X-axis push rod 4. Two first bearings 14 are mounted on the X-axis push rod 4, converting the sliding friction between the X-axis push rod 4 and the base 1 into rolling friction, thereby improving the accuracy and service life of the structure.

[0024] like Figure 2 As shown, in this embodiment, a second bearing 15 is provided on the upper surface of the Y-axis push rod 9. Two second bearings 15 are mounted on the Y-axis push rod 9, converting the sliding friction between the Y-axis push rod 9 and the base 1 into rolling friction, thereby improving the accuracy and service life of the structure.

[0025] like Figure 4 As shown, in this embodiment, the X-axis push rod 4 includes several sets of T-shaped structures arranged side by side. The T-shaped structure includes a horizontal part and a vertical part. The first compression spring 8 is disposed at the end of the horizontal part, the connecting piece 7 is disposed at the bottom of the horizontal part, and the X-axis positioning block 6 is disposed on the side of the vertical part.

[0026] like Figure 2 As shown, in this embodiment, the Y-axis push rod 9 is slidably disposed above the groove of the adjacent T-shaped structure.

[0027] like Figure 3 As shown, in this embodiment, the base 1 has a mounting groove 16, which is adapted to the X-axis push rod 4 and the Y-axis push rod 9.

[0028] like Figure 1 As shown, in this embodiment, the base 1 is provided with a positioning guide sleeve 17. When the side push module 3 requires needle puncture testing, the needle block can be precisely positioned with the positioning guide sleeve 17 via a pin.

[0029] In this embodiment, the guide bearing 5 and the inclined groove 13 are used to achieve the linkage side push in the X and Y directions. Only one power input is needed in the X direction, thereby simplifying the structure of the overall fixture.

[0030] In this embodiment, the first bearing 14 and the second bearing 15 are provided to convert the sliding friction between the side-push module 3 and the base 1 into rolling friction, thereby reducing the wear of the side-push module 3 during operation and meeting the increasingly high testing requirements of camera modules.
