Abstract
Description
Technical Field
[0001] This utility model relates to an electrical testing platform, and more particularly to a testing platform for a conversion module. Background Technology
[0002] In the field testing of electrical modules, the modules are often complex due to the presence of numerous precision components, their susceptibility to impacts, and their many irregular shapes, making precise positioning difficult. Sometimes, the modules are repeatedly flipped during testing, increasing the risk of short circuits, damage to electrical components or pins, or damage from drops. Traditional methods involve placing the modules on insulating material and testing each point individually with testing instruments. However, only one module can be tested at a time, preventing simultaneous testing of two or more modules in a specific area. Furthermore, the irregular shapes of the modules make placement inconvenient, increasing the risk of slippage or damage from drops. The operation also requires assistance from other personnel, leading to low efficiency, high concentration, fatigue, and a high error rate, ultimately hindering effective testing and verification of electrical modules.
[0003] The commonly used solutions are: 1. On-site operators place the electrical modules on an insulated platform and test and verify each point area using testing instruments; however, only one electrical module can be tested at a time, and it is not possible to test and verify two or more electrical modules for a certain area or two areas at the same time, resulting in low efficiency; 2. Using positioning fixtures to fix the test modules in one direction, it is not possible to measure multiple points at a time, and the number of measurement modules is relatively small. Frequent turning is required during the operation, and the detection contact probes are usually integrated with the positioning fixtures. After damage or wear, they cannot be frequently disassembled, which consumes a lot of effort and has a long work cycle. Utility Model Content
[0004] The purpose of this invention is to provide a conversion module testing platform to solve the problems of high error rate and low efficiency in the testing of conversion modules in the prior art.
[0005] To solve the above problems, the conversion module testing platform involved in this utility model adopts the following technical solution: A conversion module testing platform includes a testing platform with a placement area for arranging conversion modules in a row. A clamping plate for pressing the conversion modules is provided above the testing platform at the placement area. The clamping plate is slidably mounted on the testing platform. The clamping plate is driven to move up and down and be positioned downward by a vertical moving positioning structure. A testing plate is slidably mounted horizontally on one side of the placement area. A horizontal probe assembly for testing each conversion module is elastically extended and retracted on the testing plate. A vertical probe assembly for testing each conversion module is elastically extended and retracted upward in the placement area. The testing plate is driven to reciprocate and be positioned by a horizontal moving positioning structure.
[0006] The placement area is a recessed area.
[0007] A compression spring is provided between the clamping plate and the test platform.
[0008] The clamping plate is provided with downward limiting posts, which press against the test platform when the clamping plate moves downward.
[0009] The test plate is equipped with movable limiting posts, which are used to limit and press against the test platform when the test plate moves to the placement area.
[0010] A guide rod is provided between the clamping plate and the test platform. The guide rod is fixed on the test platform and slides with the sliding hole on the clamping plate.
[0011] The compression spring is sleeved on the guide rod, and its two ends press against the clamping plate and the test platform, respectively.
[0012] The vertical moving positioning structure is a first push-pull clamping quick clamp. The first push-pull clamping quick clamp is assembled on the test platform via a stand on one side of the test platform. The first push-pull clamping quick clamp includes a base fixed on the stand, a handle rotatably mounted on the base, and a slide rod slidably mounted on the base. The handle has a bent angle shape. A connecting rod is connected between the bent part of the handle and the upper end of the slide rod. The two ends of the connecting rod are rotatably mounted to the handle and the slide rod, respectively. The lower end of the slide rod is fixed to the clamping plate.
[0013] The horizontal moving positioning structure is a second push-pull clamping quick clamp.
[0014] Both the horizontal probe assembly and the vertical probe assembly include a needle sleeve, with a probe slidably mounted inside the needle sleeve to prevent detachment. A compression spring is provided between the probe and the needle sleeve. The needle sleeve of the horizontal probe assembly is interference-fitted onto the test plate, and the needle sleeve of the vertical probe assembly is interference-fitted onto the test platform.
[0015] The testing platform of this utility model has a placement area for a row of conversion modules. The conversion modules are pressed with a clamping plate. At the same time, the horizontal probe assembly and the vertical probe assembly are used to complete the testing of the conversion modules in one go. It is not easy to make mistakes, has high testing efficiency, and is not easy to damage the conversion modules.
[0016] The placement area of this utility model is a groove area. The groove wall can be used to position the conversion module, which facilitates the placement of the conversion module. No special positioning is required, which can ensure that the horizontal probe assembly and the vertical probe assembly are aligned with the test head of the conversion module.
[0017] A compression spring is provided between the clamping plate and the test platform in this utility model. When the clamping plate is not positioned by the vertical moving positioning structure, the compression spring can lift the clamping plate, which facilitates the placement of the conversion module.
[0018] The clamping plate of this utility model is provided with downward limiting posts. When the clamping plate moves downward, the downward limiting posts press against the test platform to prevent the clamping plate from pressing down excessively and to protect the conversion module.
[0019] The test plate of this utility model is provided with movable limiting posts. The movable limiting posts are used to limit and press against the test platform when the test plate moves to the placement area, so as to prevent the test plate from getting too close and protect the conversion module.
[0020] Both the horizontal probe assembly and the vertical probe assembly of this utility model include a needle sleeve, and a probe is slidably anti-detached inside the needle sleeve. A compression spring is provided between the probe and the needle sleeve. The needle sleeve of the horizontal probe assembly is interference-fitted onto the test plate, and the needle sleeve of the vertical probe is interference-fitted onto the test platform. Because the needle sleeve is assembled by interference fit, it is easy to replace and can be easily disassembled after the probe is damaged or worn. Attached Figure Description

[0024] Figure 3 for Figure 2 BB section view in the middle;

[0027] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model; that is, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0028] Specific embodiments of the conversion module testing platform involved in this utility model are described below. Figures 1-5 In the test platform 1, there is a placement area for arranging conversion modules 20 in a row. The conversion module 20 is an existing electrical component, which is approximately rectangular and has test heads on two adjacent sides. The test is performed by using probes to test the test heads.
[0029] This placement area is a recessed area with four groove walls, which can be used to position this row of conversion modules. Specifically, in this embodiment, this recess is set on a boss 2, which is assembled onto the test platform 1 by a positioning pin 3. A vertical probe assembly 4 is assembled in the placement area, and the vertical probe assembly 4 is specifically fixed to the probe fixing plate 5. The probe fixing plate 5 is fixed to the test platform 1 by a bolt assembly. This is because there is not just one vertical probe assembly 4, since not only does each conversion module have three test heads, but the conversion modules are also tested row by row. Directly installing the vertical probe assembly 4 on the test platform is inconvenient. It is more convenient to first install each vertical probe assembly 4 on the probe fixing plate 5, and then fix the probe fixing plate 5 on the test platform. This is a specific fixing and installation method that does not limit the technical solution. In other embodiments, other installation methods can be used for installation.
[0030] The vertical probe assembly 4 has a needle sleeve, within which a probe is slidably mounted to prevent detachment. A compression spring is provided between the probe and the needle sleeve, giving the probe elastic telescopic properties. The needle sleeve is forcibly fitted onto the probe fixing plate 5 by an interference fit. The vertical probe assembly is a conventional probe assembly.
[0031] A stand 6 is located on one side of the test platform 1. A push-pull clamping quick clamp 7, a commercially available component, is mounted on the stand 6. The stand 6 has a base 8, which is fixed to the stand 6 by bolts. A handle 9, which has a bent angle, is rotatably mounted on the base 8. A slide rod 10 is also slidably mounted on the base 8. A connecting rod 19 connects the bent part of the handle 9 to the upper end of the slide rod 10. Both ends of the connecting rod 19 are rotatably mounted to the handle 9 and the slide rod 10, respectively. A pressure plate 11 is fixed to the lower end of the slide rod 10. The pressure plate 11 can move up and down under the drive of the first push-pull clamping quick clamp 7 and can be locked in place after moving down. The pressure plate 11 is used to press a row of conversion modules into the groove of the test platform for positioning.
[0032] A downward limiting post 12 is arranged on the pressure plate 11. When the pressure plate 11 moves downward, the downward limiting post 12 presses against the test platform to limit the movement. Specifically, it presses against the upper edge of the boss 2 to limit the movement and prevent damage to the conversion module.
[0033] A guide rod 13 is provided between the clamping plate 11 and the test platform 1. The guide rod 13 is fixed on the test platform 1 and slides with a sliding hole on the clamping plate 11. A compression spring 14 is sleeved on the guide rod, and the two ends of the compression spring 14 press against the clamping plate 11 and the test platform 1 respectively.
[0034] A test plate 15 is mounted on one side of the placement area on the test platform 1. The test plate 15 slides horizontally on the test platform 1 and is slidably assembled on the test platform 1 via a slide rail structure 16, which is a common sliding assembly method. The test plate 15 is moved and positioned horizontally by a push-pull clamping quick clamp. This push-pull clamping quick clamp is the second push-pull clamping quick clamp 21, which is also a commercially available part. Its basic structure and working principle are the same as the first push-pull clamping quick clamp, and will not be described in detail here. A horizontal probe assembly 17 for testing each conversion module is elastically and telescopically mounted on the test plate. The horizontal probe assembly 17 has the same structure as the vertical probe assembly and is also elastic. The needle sleeve of the horizontal probe assembly 17 is interference-fitted onto the test plate 15.
[0035] A movable limiting post 18 is provided on the test plate 15. The movable limiting post 18 is used to limit and press against the test platform 1 when the test plate 15 moves to the placement area. Specifically, it presses against the side wall of the boss 2.
[0036] The vertical and horizontal moving positioning structures in the above embodiments are both push-pull clamping quick clamps. In other embodiments, they can also be other linear drive structures with positioning functions, such as hydraulic cylinders that can maintain pressure.
[0037] The placement area in the above embodiments is a recessed area, or it can be just a single area. Other methods can be used for positioning, or it can be manually positioned to place it in the correct location.
[0038] In the above embodiment, a compression spring is provided between the clamping plate and the test platform; in other embodiments, this spring may not be provided.
[0039] The above embodiments provide a specific installation method for the compression spring. In other embodiments, other structural forms in the prior art can also be used for installation.
[0040] The above embodiments include a downward limiting post and a moving limiting post. In other embodiments, these may not be provided, as the probe components are all flexible and can be designed with more margin.
[0041] In the above embodiments, the probe assembly's needle sleeve is installed using an interference fit, which facilitates disassembly. Other installation methods may also be used in other embodiments.
[0042] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions made to this utility model that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
