Description

Technical Field

[0001] This utility model relates to the field of testing fixtures, and in particular to a product testing fixture with a multi-functional clamping structure. Background Technology

[0002] In the manufacturing process of industrial electronic products, such as LED potted power supplies, power-on testing is required before shipment to ensure stable performance and reliable quality. To improve testing efficiency and meet the needs of batch testing, a product testing fixture is typically used to clamp and fix multiple products under test onto the testing device. The clamping structure secures the products under test, and the terminals of each product are connected to the product under test via conductive wires to achieve synchronous power-on testing.

[0003] However, traditional clamping structures are mostly rigid fixed structures or unidirectional adjustable mechanisms, which often suffer from low clamping efficiency and poor adaptability. On the one hand, in batches of products of the same specification, operators need to repeatedly disassemble or individually adjust the position of the clamps for electronic products of different sizes or models, which is not only cumbersome but also affects testing efficiency. On the other hand, most existing product testing fixtures adjust the position or clamping spacing of the clamping blocks one by one, which cannot achieve the linkage adjustment of multiple clamping end blocks, resulting in defects such as high workload, inconsistent positioning, and low batch clamping accuracy.

[0004] Therefore, it is necessary to propose a product testing fixture with a multi-functional clamping structure that can achieve symmetrical linkage adjustment of the clamping structure and adapt to the rapid clamping of batches of products of the same specification. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a product testing fixture with a multi-functional clamping structure. This fixture solves problems such as high workload, inconsistent positioning, and low batch clamping accuracy for batches of products of the same specification, thereby improving the clamping accuracy in the batch testing process of electronic products.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a product testing fixture with a multi-functional clamping structure, including:

[0008] The driving device includes a longitudinal guide rail, two transverse guide rails, a bidirectional lead screw, and a driving component. The two transverse guide rails are slidably connected to the longitudinal guide rail, and the extension directions of the two transverse guide rails are perpendicular to the extension direction of the longitudinal guide rail. The bidirectional lead screw is parallel to the longitudinal guide rail, passes through the two transverse guide rails, and is threadedly connected to the two transverse guide rails. The driving component is disposed between the two transverse guide rails and is drivenly connected to the bidirectional lead screw. The driving component can drive the bidirectional lead screw to rotate, so that the two transverse guide rails slide symmetrically along the extension direction of the longitudinal guide rail.

[0009] The clamping structure includes a plurality of clamping end blocks slidably connected to any of the transverse guide rails, and a linkage rod connecting adjacent clamping end blocks. Each clamping end block is slidably connected to any of the transverse guide rails, and each clamping end block has a slot at each of its four corners for clamping the product to be tested.

[0010] When the two transverse guide rails slide symmetrically along the extension direction of the longitudinal guide rail, the clamping structure adjusts the longitudinal spacing as the two transverse guide rails slide symmetrically.

[0011] When any one of the clamping end blocks moves along the extension direction of the transverse guide rail, the remaining clamping end blocks simultaneously move at the same distance along the extension direction of the transverse guide rail via the linkage rod, thereby enabling synchronous clamping and positioning of multiple products to be tested.

[0012] Among them, every two corresponding slots on any one of the transverse guide rails, together with two slots at symmetrical positions on the other transverse guide rail, constitute four slots, forming a positioning space for clamping a product to be tested.

[0013] Furthermore, each of the linkages includes a first link and a second link, the center of the first link, the center of the second link, and any of the clamping end blocks are rotatably connected together, one end of the first link is rotatably connected to one end of the second link on the adjacent clamping end block, and the other end of the first link is rotatably connected to the other end of the second link on the adjacent clamping end block.

[0014] Furthermore, each of the card slots is square, and the corners of the product under test are adapted to the card slots.

[0015] Furthermore, each of the slots has an inner wall provided with an elastic rubber layer, which provides friction and cushioning when clamping the product to be tested.

[0016] Furthermore, the driving component is a hand-tightening rotating component, which is located between the two transverse guide rails and is connected to the bidirectional lead screw. The user can manually rotate the hand-tightening rotating component to drive the bidirectional lead screw to rotate, so that the two transverse guide rails slide symmetrically along the longitudinal guide rail direction.

[0017] Furthermore, there are multiple bidirectional lead screws, and the driving member is connected to multiple lead screws in a transmission connection, with each bidirectional lead screw arranged at equal intervals.

[0018] Furthermore, a first guide slider is provided between the clamping end block and the transverse guide rail, the first guide slider enabling the clamping end block to slide smoothly on the transverse guide rail.

[0019] Furthermore, a second guide slider is provided between the clamping end block and the transverse guide rail, the second guide slider enabling the transverse guide rail to slide smoothly on the longitudinal guide rail.

[0020] Furthermore, the product testing fixture with a multi-functional clamping structure also includes a base, on which the longitudinal guide rail is fixed.

[0021] Furthermore, the product testing fixture with the multi-functional clamping structure also includes multiple terminals, all of which are located on the base. Each terminal is electrically connected to the terminal of the adjacent product under test, so that the products under test can be powered on and tested uniformly.

[0022] The beneficial effects of this utility model are:

[0023] Two transverse guide rails are slidably connected to a longitudinal guide rail, with the extension directions of the two transverse guide rails perpendicular to the extension directions of the longitudinal guide rails. A bidirectional lead screw is parallel to the longitudinal guide rail, passes through the two transverse guide rails, and is threadedly connected to them. A drive unit is located between the two transverse guide rails and is connected to the bidirectional lead screw for transmission. The drive unit can drive the bidirectional lead screw to rotate, causing the two transverse guide rails to slide symmetrically along the extension direction of the longitudinal guide rail. Each clamping end block is slidably connected to any one of the transverse guide rails, and each clamping end block has slots at its four corners for clamping the product to be tested. When the two transverse guide rails slide symmetrically along the extension direction of the longitudinal guide rail, the clamping structure adjusts the longitudinal spacing accordingly. When any one clamping end block moves along the extension direction of the transverse guide rail, the other clamping end blocks move simultaneously along the extension direction of the transverse guide rail via linkage rods at equal distances, enabling synchronous clamping and positioning of multiple products to be tested. Each pair of corresponding slots on any horizontal guide rail, together with two slots symmetrically positioned on another horizontal guide rail, forms four slots, creating a positioning space for clamping a product under test. This enables symmetrical and coordinated adjustment of the clamping structure, accommodating rapid clamping of batches of products of the same specification. It ensures uniform and consistent positioning of each product under test, significantly improving positioning accuracy and operational efficiency during batch testing, and enabling rapid batch clamping operations.

[0029] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0030] Please refer to Figures 1 to 3This utility model proposes a product testing fixture with a multi-functional clamping structure, including a driving device and a clamping structure. The driving device includes a longitudinal guide rail 110, two transverse guide rails 120, a bidirectional lead screw 130, and a driving component 140. The two transverse guide rails 120 are slidably connected to the longitudinal guide rail 110, and the extension directions of the two transverse guide rails 120 are perpendicular to the extension direction of the longitudinal guide rail 110. The bidirectional lead screw 130 is parallel to the longitudinal guide rail 110, passes through the two transverse guide rails 120, and is threadedly connected to the two transverse guide rails 120. The driving component... The drive unit 140 is located between two transverse guide rails 120 and is connected to the bidirectional lead screw 130 for transmission. The drive unit 140 can drive the bidirectional lead screw 130 to rotate, so that the two transverse guide rails 120 slide symmetrically along the extension direction of the longitudinal guide rail 110. The clamping structure includes multiple clamping end blocks 210 slidably connected to any transverse guide rail 120 and a linkage rod 220 connecting adjacent clamping end blocks 210. Each clamping end block 210 is slidably connected to any transverse guide rail 120, and each clamping end block 210 has a slot 211 at each of its four corners for clamping the product 1 to be tested.

[0031] When the two transverse guide rails 120 slide symmetrically along the extension direction of the longitudinal guide rail 110, the clamping structure adjusts the longitudinal spacing as the two transverse guide rails 120 slide symmetrically. When any clamping end block 210 moves along the extension direction of the transverse guide rail 120, the other clamping end blocks 210 move simultaneously along the extension direction of the transverse guide rail 120 through the linkage rod 220 at equal distances, so as to synchronously clamp and position multiple products 1 to be tested.

[0032] Among them, every two corresponding slots 211 on any horizontal guide rail 120 together with two slots 211 at symmetrical positions on another horizontal guide rail 120 constitute four slots 211, forming a positioning space for clamping a product 1 to be tested.

[0033] Specifically, the driving device includes a longitudinal guide rail 110, two transverse guide rails 120, a bidirectional lead screw 130, and a driving component 140. The two transverse guide rails 120 are slidably connected to the longitudinal guide rail 110 and extend in a direction perpendicular to the longitudinal guide rail 110. The bidirectional lead screw 130 is arranged parallel to the longitudinal guide rail 110 and passes through the two transverse guide rails 120 and is threadedly connected to them. When the bidirectional lead screw 130 is rotated by the driving component 140, since the thread directions on both sides of the bidirectional lead screw 130 are opposite, the two transverse guide rails 120 can be driven to slide symmetrically along the longitudinal guide rail 110, thereby achieving synchronous adjustment of the clamping structure in the longitudinal direction. The clamping structure includes multiple clamping end blocks 210 slidably connected to any one of the transverse guide rails 120. Adjacent clamping end blocks 210 are mechanically linked together by a linkage rod 220. Each clamping end block 210 has a slot 211 at each of its four corners. When the operator pushes one of the clamping end blocks 210 to move along the transverse guide rail 120, the other clamping end blocks 210 can slide at equal distances through the linkage rod 220, thereby realizing the one-time synchronous positioning and clamping of multiple products.

[0034] The slot 211 is used to clamp the corner of the product to be tested 1. Its layout is such that every two opposing slots 211 located on the same transverse guide rail 120, together with two slots 211 at corresponding positions on another transverse guide rail 120, form a four-point positioning clamping space, thereby achieving stable clamping of a product to be tested 1.

[0035] It is important to understand that existing electronic product testing fixtures generally suffer from structural rigidity and lack of linkage adjustment capabilities. This is especially problematic when batch testing industrial electronic products such as LED potted power supplies, where the clamping process is time-consuming, involves repetitive labor, and results in poor product alignment accuracy, severely impacting power-on testing efficiency and product positioning consistency. This solution provides a product testing fixture with a multi-functional clamping structure that simultaneously addresses technical issues such as inconvenient clamping spacing adjustment, inconsistent clamping, and poor adaptability.

[0036] In summary, by setting up a bidirectional lead screw 130 for the drive device and symmetrically arranged transverse guide rails 120, the longitudinal spacing of multiple clamping blocks can be synchronously adjusted under the action of a single drive component 140, effectively solving the problems of complex and inefficient longitudinal adjustment of existing tooling. The clamping end blocks 210 are cross-linked through linkage rods 220, ensuring that multiple clamping blocks maintain equidistant movement in the transverse direction, guaranteeing uniform and consistent positioning and centering of each product, greatly improving positioning accuracy and operational efficiency during batch testing. Each pair of corresponding slots 211 on any transverse guide rail 120, together with two slots 211 symmetrically positioned on another transverse guide rail 120, constitute four slots 211. This four-slot positioning structure enhances the stability of product clamping, preventing displacement or loosening, and is suitable for use with industrial electronic products of the same specification. Without adding a complex drive system, this technical solution achieves flexible, fast, and highly consistent batch clamping operations with a simple mechanical structure, significantly improving the automation level and production cycle of the testing process.

[0037] Please refer to Figure 3 In this embodiment, each linkage 220 includes a first link 221 and a second link 222. The center of the first link 221, the center of the second link 222, and any clamping end block 210 are rotatably connected together. One end of the first link 221 is rotatably connected to one end of the second link 222 on the adjacent clamping end block 210, and the other end of the first link 221 is rotatably connected to the other end of the second link 222 on the adjacent clamping end block 210.

[0038] Specifically, the linkage 220 between each clamping end block 210 includes a first link 221 and a second link 222, used to achieve equidistant linkage of the clamping end blocks 210 on the transverse guide rail 120. The middle parts of the first link 221 and the second link 222 are connected to any clamping end block 210 by a rotatable hinge; one end of the first link 221 is rotatably connected to one end of the second link 222 on the adjacent clamping end block 210, and the other end of the first link 221 is also rotatably connected to the other end of the second link 222 on the next clamping end block 210. This forms a continuous "rhomboid" linkage structure. When the operator pushes any clamping end block 210 to move along the transverse guide rail 120, the adjacent clamping end blocks 210 will slide in linkage at equal distances under the drive of the linkage mechanism, thereby maintaining a consistent spacing between the clamping blocks.

[0039] In this embodiment, each slot 211 is square, and the corners of the product 1 to be tested are adapted to the slot 211.

[0040] Specifically, each clamping end block 210 has a square slot 211 at each of its four corners. The inner dimensions of the square slot 211 are adapted to the corner contours of the electronic product under test (e.g., an LED potted power supply). Specifically, the square slots 211 are arranged at right angles along the two vertical sides of the clamping end block 210 to fit the corners of the product under test, enabling four-point positioning of the product during clamping. The four square slots 211 on the paired clamping end blocks 210 at both ends of the transverse guide rail 120 form a clamping unit, thus collectively creating a positioning space for accommodating and fixing a single product.

[0041] In this embodiment, each slot 211 has an elastic rubber layer 212 on its inner sidewall. The elastic rubber layer 212 is used to provide friction and buffering force when clamping the product to be tested 1.

[0042] Specifically, an elastic rubber layer 212 is provided on the inner wall of the square slot 211 of each clamping end block 210. The rubber layer can be fixedly installed on the inner surface of the slot 211 by means of pasting, covering or embedding, so as to provide a certain elastic buffer and friction during product clamping.

[0043] In this embodiment, the driving component 140 is a hand-tightening rotating component, which is located between two transverse guide rails 120 and is connected to the bidirectional lead screw 130 for transmission. The user manually rotates the hand-tightening rotating component to drive the bidirectional lead screw 130 to rotate, so that the two transverse guide rails 120 slide symmetrically along the longitudinal guide rail 110. There are multiple bidirectional lead screws 130, and the driving component 140 is connected to multiple lead screws for transmission, with each bidirectional lead screw 130 arranged at equal intervals.

[0044] Specifically, to facilitate quick adjustment of the longitudinal spacing of the clamping structure by the operator, the drive component 140 is a hand-tight rotating component, which is located between the two transverse guide rails 120 and is connected to at least one bidirectional lead screw 130. The hand-tight rotating component is a knob structure with anti-slip texture, and the rotation direction matches the helical direction of the lead screw. When the operator manually rotates the knob, it drives the bidirectional lead screw 130 to rotate synchronously. Since the two ends of the bidirectional lead screw 130 are respectively threaded to the two transverse guide rails 120 with opposite thread directions, symmetrical sliding of the two transverse guide rails 120 on the longitudinal guide rail 110 can be achieved.

[0045] Please refer to Figure 2 In this embodiment, there are multiple bidirectional lead screws 130, and the drive member 140 is connected to the multiple lead screws for transmission. Each bidirectional lead screw 130 is arranged at equal intervals.

[0046] Specifically, to improve the synchronous adjustment capability of the overall clamping structure on a large-sized tooling platform, multiple bidirectional lead screws 130 are provided on the transverse guide rail 120, with each bidirectional lead screw 130 arranged at equal intervals along the longitudinal guide rail 110. The multiple bidirectional lead screws 130 are threadedly connected to the transverse guide rail 120 and are connected to a unified drive component 140 through gears, couplings, or other structures to ensure that the multiple lead screws can rotate synchronously.

[0047] Please refer to Figure 1 In this embodiment, a first guide slider 230 is provided between the clamping end block 210 and the transverse guide rail 120, which allows the clamping end block 210 to slide smoothly on the transverse guide rail 120. A second guide slider 150 is provided between the clamping end block 210 and the transverse guide rail 120, which allows the transverse guide rail 120 to slide smoothly on the longitudinal guide rail 110.

[0048] In this embodiment, the product testing fixture with a multi-functional clamping structure also includes a base 300, and a longitudinal guide rail 110 is fixed on the base 300.

[0049] Specifically, the longitudinal guide rail 110 is fixedly mounted on the base 300 to support and guide the symmetrical sliding adjustment of the entire clamping structure, thereby supporting the weight and operating force generated by the transverse guide rail 120, the clamping end block 210, and the test product. The longitudinal guide rail 110 is fixed to the top of the base 300 with bolts to ensure that the guide rail does not deform or loosen during the adjustment process.

[0050] In this embodiment, the product testing fixture with a multi-functional clamping structure also includes multiple terminals 400, all of which are disposed on the base 300. Each terminal 400 is electrically connected to the terminal of the adjacent product under test 1 so that the product under test 1 can be powered on and tested uniformly.

[0051] Specifically, multiple terminals 400 are provided on the side of the base 300 facing the product under test (DUT) 1 for electrical connection to the power interface of each DUT 1. Each terminal 400 is connected to a corresponding power terminal of the DUT 1 clamped in the slot 211 via a conductive wire, thereby achieving unified power supply after clamping. The base 300 also includes an access terminal 500 for connecting to equipment. The access terminal 500 is electrically connected to the multiple terminals 400 to form an electrical path. Test power supplies, test instruments, or control systems can be quickly connected to the entire test fixture through the access terminal 500. The access terminal 500 for connecting to equipment can be used to perform batch power-on testing on batches of DUT 1 after being clamped.

[0052] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
