Description

Technical Field

[0001] This utility model relates to the field of automated testing, and more specifically, to a programming test fixture. Background Technology

[0002] In the electronic product manufacturing process, electrical connection testing is required to ensure the complete functionality of electronic products after programming. For products with some test points located on the side, a clamping force must be applied from above to fix the product during testing, while a reliable electrical connection is achieved from the side. However, the structural design of existing testing fixtures often struggles to balance positioning stability and electrical connection accuracy. Furthermore, performing multiple actions, such as clamping and lateral connection, can easily cause motion interference, affecting the efficiency of product loading and unloading. Utility Model Content

[0003] The purpose of this invention is to provide a programming and testing fixture that can stably position the product under test, ensure the reliability of electrical connections, and has a reasonable layout that can effectively avoid motion interference and improve testing efficiency.

[0004] A programming and testing fixture, comprising: Platform; Multiple positioning seats are arranged on the support platform for placing products; A clamping assembly, movably mounted on the support platform, is used to move horizontally above the positioning seat and descend to clamp the product; and The test components, which are configured one-to-one with the positioning seats, include a test drive component, a first test connection component, and a second test connection component. The first test connection component and the second test connection component are disposed opposite to each other on both sides of the positioning seat and are slidably connected to the support platform. The test drive component is used to synchronously drive multiple first test connection components and multiple second test connection components to slide, so that the first test connection components and the second test connection components are electrically connected to the product from both sides of the product, respectively.

[0005] In the above technical solution, by setting a clamping component that can move horizontally and descend to press down, the product can be effectively clamped during testing to ensure its stability. After testing, it moves horizontally away from the positioning seat to avoid interference with the product's loading and unloading movement, thus ensuring testing efficiency. The first and second test connection components in the testing assembly are synchronously driven by the same drive unit, ensuring balanced force on the product during lateral support and electrical testing, thereby improving testing stability. The overall structure of this utility model is compact and can meet the needs of parallel testing of multiple products.

[0006] Furthermore, the clamping assembly includes a horizontal drive component, a slider, a vertical drive component, a lifting seat, and multiple pressure blocks. The horizontal drive component is disposed on the bearing platform. The slider is connected to the output end of the horizontal drive component and is slidably connected to the bearing platform. The vertical drive component is mounted on the slider and connected to the lifting seat. The pressure blocks are arranged on the lifting seat and are configured one-to-one with the positioning seats.

[0007] In the above technical solution, the horizontal drive component works with the slider to realize the horizontal movement of the clamping assembly, and the vertical drive component controls the vertical movement of the lifting seat, so that multiple pressure blocks can be pressed down synchronously, ensuring that all products are subjected to uniform force and improving the reliability of the clamping action.

[0008] Furthermore, the support platform is symmetrically provided with guide rails on both sides, and there are two sliders, each of which is slidably connected to the corresponding guide rail.

[0009] In the above technical solution, the symmetrically arranged guide rails provide support for the dual sliders, while avoiding the risk of jamming caused by sliding on one side. The design of the dual sliders sharing the load enhances the stability of movement, prevents the lifting seat from tilting, and ensures the vertical alignment accuracy between the pressure block and the product.

[0010] Furthermore, there are two vertical drive components, which are respectively mounted on the two sliders.

[0011] In the above technical solution, the two vertical drive components drive the corresponding sliders independently, which can drive the lifting seat to rise and fall synchronously from both sides, avoiding tilting of the lifting seat and ensuring consistent pressure on the product on each positioning seat.

[0012] Furthermore, the first test connection component and / or the second test connection component include a connection block on which a plurality of probes for electrical connection with the product are passed through.

[0013] In the above technical solution, the probe array is laid out through the connecting block, which can flexibly arrange the probes according to the product interface position to adapt to the testing needs of different product models. The connecting block provides an overall mounting reference for the probes, reduces single-needle vibration, and improves electrical contact stability.

[0014] Furthermore, the connecting block is slidably connected to the support platform and connected to the test drive component.

[0015] In the above technical solution, the test driver can drive the connecting block to slide, thereby realizing the connection and separation of the probe to the product.

[0016] Furthermore, the upper end of the positioning seat is provided with a positioning groove, and the two sides of the positioning groove are provided with opening grooves. The opening grooves are used to expose the two sides of the product so as to connect the first test connection component and the second test connection component.

[0017] In the above technical solution, the positioning groove positions the product, and the two side openings reserve operating space for the first test connection component and the second test connection component, allowing them to directly contact the target area of ​​the product and ensuring the stability of the electrical connection.

[0018] Furthermore, it also includes a base located below the support platform, and the test drive component is mounted on the base.

[0019] In the above technical solution, the test drive component is located on the base and below the support platform, which can effectively connect the first test connection component and the second test connection component, and the overall layout is compact and reasonable.

[0020] Compared with existing technologies, the advantages of this invention are: by setting a clamping component that can move horizontally and descend to press down, the product can be effectively clamped during testing, ensuring product stability. After testing, it moves horizontally away from the positioning seat, avoiding interference with the product loading and unloading movement and ensuring testing efficiency. The first and second test connection components in the testing assembly are synchronously driven by the same drive unit, ensuring balanced force on the product during lateral support and electrical testing, thus improving testing stability. The overall structure of this invention is compact and can meet the needs of parallel testing of multiple products. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] Please refer to Figures 1 to 4 In a preferred embodiment, the programming and testing fixture of this utility model mainly includes a support platform 1, positioning seats 2, clamping components 3, and testing components 4. Multiple positioning seats 2 are arranged on the support platform 1 for placing the product. The clamping components 3 are movably disposed on the support platform 1 and are used to move horizontally above the positioning seats 2 and descend to clamp the product. The testing components 4 are arranged one-to-one with the positioning seats 2 and include a test drive component 41, a first test connection component 42, and a second test connection component 43. The first test connection component 42 and the second test connection component 43 are disposed opposite each other on both sides of the positioning seats 2 and are slidably connected to the support platform 1. The test drive component 41 is used to synchronously drive the multiple first test connection components 42 and the multiple second test connection components 43 to slide, so that the first test connection components 42 and the second test connection components 43 are electrically connected to the product from both sides respectively.

[0029] By incorporating a horizontally movable and lowerable clamping component 3, the product can be effectively clamped during testing, ensuring its stability. After testing, it moves horizontally away from the positioning seat 2, avoiding interference with product loading and unloading and ensuring testing efficiency. In the testing component 4, the first test connection component 42 and the second test connection component 43 are synchronously driven by the same drive unit, ensuring balanced force on the product during lateral support and electrical testing, thus improving testing stability. The overall structure of this invention is compact and can meet the needs of parallel testing of multiple products.

[0030] Please refer to Figure 2The clamping assembly 3 includes a horizontal drive component 31, a slider 32, a vertical drive component 33, a lifting seat 34, and multiple pressure blocks 35. The horizontal drive component 31 is mounted on the support platform 1. The slider 32 is connected to the output end of the horizontal drive component 31 and slidably connected to the support platform 1. The vertical drive component 33 is mounted on the slider 32 and connected to the lifting seat 34. The pressure blocks 35 are arranged on the lifting seat 34 and correspond one-to-one with the positioning seats 2. For example, both the horizontal drive component 31 and the vertical drive component 33 can be existing linear drive devices, such as cylinders. The extension direction of the lifting seat 34 is the same as the arrangement direction of the positioning seats 2, and the pressure blocks 35 correspond one-to-one with the positioning seats 2, so that the products on the positioning seats 2 can be clamped during descent. The horizontal drive component 31 and the slider 32 cooperate to realize the horizontal movement of the clamping assembly 3, and the vertical drive component 33 controls the vertical movement of the lifting seat 34, so that the multiple pressure blocks 35 can be pressed down synchronously, ensuring that all products are subjected to uniform force and improving the reliability of the clamping action.

[0031] The support platform 1 has symmetrical guide rails 11 on both sides, and two sliders 32, each slidably connected to its corresponding guide rail 11. The symmetrically arranged guide rails 11 provide support for the two sliders 32, while avoiding the risk of jamming caused by sliding on one side. The design of the two sliders 32 sharing the load enhances the stability of movement, prevents the lifting seat 34 from tilting, and ensures the vertical alignment accuracy between the pressure block 35 and the product.

[0032] In this embodiment, there are two vertical drive members 33, which are respectively mounted on two sliders 32. The two vertical drive members 33 independently drive the corresponding sliders 32, and can synchronously drive the lifting seat 34 to rise and fall from both sides, avoiding tilting of the lifting seat 34 and ensuring consistent pressure on the product on each positioning seat 2.

[0033] Please refer to Figure 3 The second test connection assembly 43 includes a connection block 431, on which a plurality of probes 432 for electrical connection with the product are mounted. Exemplarily, the probes 432 can be existing flexible probes 432, with their axial direction horizontal and their ends facing the positioning seat 2. The arrangement of the probe array passing through the connection block 431 allows for flexible arrangement of the probes 432 according to the product interface location, adapting to the testing needs of different product models. The connection block 431 provides an overall mounting reference for the probes 432, reducing single-needle vibration and improving electrical contact stability.

[0034] It should be noted that the first test connection component 42 may adopt the same structure as the second test connection component 43, which will not be described in detail here. In other possible embodiments, one of the first test connection component 42 and the second test connection component 43 may be equipped with probe 432, while the other may not be equipped with probe 432, thereby achieving electrical connection with the product from one side and meeting the testing requirements of different products.

[0035] The upper end of the positioning base 2 is provided with a positioning groove 21, and opening slots 22 are provided on both sides of the positioning groove 21. The opening slots 22 are used to expose both sides of the product for connecting the first test connection component 42 and the second test connection component 43. The positioning groove 21 matches the shape and contour of the product to position the product, and the opening slots 22 on both sides reserve operating space for the first test connection component 42 and the second test connection component 43, allowing them to directly contact the target area of ​​the product and ensuring the stability of the electrical connection and side support.

[0036] The programming and testing fixture of this utility model also includes a base 5, which is located below the support platform 1, and a test drive component 41 is disposed on the base 5. For example, the base 5 and the support platform 1 are connected by several support rods. The test drive component 41 is disposed on the base 5 and located below the support platform 1, which can effectively connect the first test connection component 42 and the second test connection component 43. The overall layout is compact and reasonable.

[0037] To facilitate understanding of this technical solution, the testing process is described below: The product is fed to the positioning seat 2 by an external feeding mechanism. Then, the horizontal drive 31 drives the slider 32 to move, so that the lifting seat 34 is vertically aligned with the positioning seat 2. The vertical drive 33 drives the lifting seat 34 to descend, and the pressure block 35 presses the product from above. At the same time, the test drive 41 synchronously drives the first test connection component 42 and the second test connection component 43 to move closer to the positioning seat 2. The first test connection component 42 and the second test connection component 43 abut against the product from both sides, so that the probe 432 contacts the test contact point of the product for testing. After the test is completed, the test drive 41 drives the first test connection component 42 and the second test connection component 43 to reset. At the same time, the horizontal drive 31 drives the lifting seat 34 to reset. Then, the unloading mechanism (not shown) unloads the tested product.
