Abstract
Description
Technical Field
[0001] This utility model relates to the field of chip manufacturing equipment technology, and in particular to a cross-line device for preventing poor wire snagging. Background Technology
[0002] In chip manufacturing, wire clamps are fixtures used to connect and secure the tiny circuitry within a chip or between the chip and external testing equipment. Their primary purpose is to ensure stable and precise circuit connections during testing, packaging, and other manufacturing processes. Chip circuitry is extremely delicate, and wire clamps help establish reliable electrical connections, enabling signals to be transmitted accurately between different parts of the chip or between the chip and testing instruments.
[0003] However, the existing cross-connect clamps have a smooth surface. The smooth surface of the cross-connect clamps can cause the wires to not be clamped or to come off the cross-connect clamps directly when pressing thin wires. This results in defective chips during the chip production process, causing economic losses. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a cross-line device to prevent poor wire snagging.
[0005] This utility model is achieved using the following technical solution: a cross-line device for preventing poor wire snagging, comprising a base, a wire assemblies for the wire snagging are installed on one side of the base, and cross-line clamp assemblies for pressing the copper wires together on both sides of the wire assemblies. Each cross-line clamp assembly is provided with an anti-detachment component to prevent the copper wires from falling off, and an adjustment component at the bottom of each cross-line clamp assembly to allow the cross-line clamp assembly to hold copper wires of different thicknesses. Each cross-line clamp assembly includes a base plate fixedly installed on the base, an mounting plate fixedly installed on the top of the base plate and fixedly installed on the base, a clamping post between the base plate and the mounting plate, and a limiting post fixedly installed at one end of the clamping post. One end of the limiting post extends upward through the mounting plate. The anti-detachment component includes a limiting plate on the base plate and a rubber plate fixedly installed on the limiting plate.
[0006] With the above technical solution, after the copper wire is on the two cross clamp assemblies, the two anti-detachment components will prevent the copper wire from falling off the cross clamp assemblies due to insufficient clamping force. Therefore, the anti-detachment components can prevent the copper wire from falling off. According to the different thicknesses of the copper wire, the adjustment component can be moved, which will move the anti-detachment components to adapt to the current copper wire, thus completely preventing the copper wire from being poorly attached to the cross clamp assemblies.
[0007] As a further improvement to the above solution, each of the two limiting posts is fitted with a push spring, and the two ends of each push spring abut against the adjacent mounting plate and the clamping post, respectively.
[0008] Through the above technical solution, the pushing spring will continuously push the pressing column to fit with the rubber plate.
[0009] As a further improvement of the above solution, a pushing plate arranged in a "C" shape is sleeved on each of the bottom plates. Sliding grooves are formed on both sides of each limiting plate, and limiting bars are slidably inserted into the interior of each sliding groove. Each limiting bar is fixedly installed with the adjacent pushing plate.
[0010] Through the above technical solution, when the pushing plate moves upward, the limiting plate will move upward, thereby causing the rubber plate to move upward. In this way, the pressing column will be pushed, and the pushing spring will be compressed, so that the clamping force between the pressing column and the rubber plate becomes larger.
[0011] As a further improvement of the above solution, the adjusting component includes a fixing plate fixedly installed at the bottom of the bottom plate and having a plurality of pushing grooves formed on both sides, and limiting blocks arranged inside each pushing groove. A plurality of reset springs are fixedly installed on one side of each limiting block, and one end of each reset spring is fixedly installed with the inner wall of the pushing groove.
[0012] Through the above technical solution, after the pushing plate moves upward, it will be blocked by the limiting block and cannot descend, and the reset spring will always keep the limiting block in its original position, which is convenient for the limiting block to limit the pushing plate.
[0013] As a further improvement of the above solution, one side of each limiting block is arranged in an inclined shape.
[0014] Through the above technical solution, during the movement of the pushing plate, the limiting block will be pushed due to the inclined surface of the limiting block, so that the limiting block can be reset under the push of the reset spring, thereby fixing the position of the pushing plate.
[0015] As a further improvement of the above solution, a limiting port adapted to the fixing plate is formed on the bottom side of each pushing plate.
[0016] Through the above technical solution, the fixing plate can pass through the pushing plate during the upward movement of the pushing plate, preventing the pushing plate from being unable to move upward.
[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0018] This invention, by setting up crossover clamp components, anti-detachment components, and adjustment components, ensures that once the copper wire is on the two crossover clamp components, the two anti-detachment components prevent insufficient clamping force from causing the copper wire to detach from the crossover clamp components. Therefore, the anti-detachment components can prevent the copper wire from falling off. According to the different thicknesses of the copper wire, the adjustment components can be moved, which in turn moves the anti-detachment components to adapt to the current copper wire, thus completely preventing the problem of poor wire attachment on the crossover clamp components.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0025] Please combine Figures 1-3 This embodiment of a crossover device for preventing poor wire snagging includes a base 1. A crossover assembly 2 for crossover is installed on one side of the base 1. Both sides of the crossover assembly 2 are provided with crossover clamp assemblies for pressing the copper wires together. Each crossover clamp assembly is provided with an anti-detachment component to prevent the copper wires from falling off. The bottom of each crossover clamp assembly is provided with an adjustment component that allows the crossover clamp assembly to hold copper wires of different thicknesses.
[0026] The cross-line clamp assembly includes a bottom plate 301 fixedly installed on the base 1, a mounting plate 302 arranged on the top of the bottom plate 301 and fixedly installed with the base 1, a pressing column 303 arranged between the bottom plate 301 and the mounting plate 302, and a limiting column 304 fixedly installed at one end of the pressing column 303. One end of the limiting column 304 penetrates upward through the mounting plate 302. The anti-dropping assembly includes a limiting plate 401 arranged on the bottom plate 301 and a rubber plate 402 fixedly installed on the limiting plate 401. A pushing spring 6 is sleeved on each of the two limiting columns 304, and two ends of each pushing spring 6 are respectively abutted against the adjacent mounting plate 302 and the pressing column 303.
[0027] The pushing spring 6 will always push the pressing column 303 to fit with the rubber plate 402, so that the copper wire can maintain friction with the rubber plate 402, thereby preventing the copper wire from easily separating from the pressing column 303.
[0028] A pushing plate 7 arranged in a "C" shape is sleeved on each bottom plate 301. Sliding grooves are formed on both sides of each limiting plate 401, and a limiting strip 8 is slidably inserted into each sliding groove. Each limiting strip 8 is fixedly installed with the adjacent pushing plate 7.
[0029] When the pushing plate 7 moves upward, the limiting plate 401 will move upward, so that the rubber plate 402 will move upward, which will push the pressing column 303, and the pushing spring 6 will be compressed, so that the clamping force between the pressing column 303 and the rubber plate 402 becomes larger.
[0030] The adjusting assembly includes a fixing plate 501 fixedly installed at the bottom of the bottom plate 301 and having a plurality of pushing grooves formed on both sides, and a limiting block 502 arranged inside each pushing groove. A plurality of reset springs 503 are fixedly installed on one side of each limiting block 502, one end of each reset spring 503 is fixedly installed with the inner wall of the pushing groove, one side of each limiting block 502 is arranged in an inclined shape, and a limiting port adapted to the fixing plate 501 is formed on the bottom side of each pushing plate 7.
[0031] When the pushing plate 7 moves upward, it will be blocked by the limiting block 502 and cannot move downward, and the reset spring 503 will always keep the limiting block 502 in its original position, which is convenient for the limiting block 502 to limit the pushing plate 7.
[0032] The implementation principle of a cross-line device for preventing poor wire hanging in the embodiment of the present application is as follows: Initially, the pushing spring 6 is in a relaxed state, neither compressed nor expanded. The thicker copper wire will be pressed by the pressing column 303 on the rubber plate 402. When the copper wire crosses the line, the copper wire is located between the two pressing columns 303 and the two rubber plates 402 and is pressed by the pressing column 303 on the rubber plate 402.
[0033] This allows the compatible copper wire to rub against the rubber plate 402, preventing the clamping post 303 from being too smooth to clamp the copper wire, and avoiding the copper wire from separating from the clamping post 303 with slight pulling.
[0034] When the copper wire is small in size and the clamping column 303 and rubber plate 402 cannot clamp it tightly, simply move the push plate 7 upward. The upward movement of the push plate 7 will also move the limiting plate 401 upward, thereby causing the rubber plate 402 to move upward as well. This will push the clamping column 303, causing it to squeeze the push spring 6. After the push spring 6 is compressed, it will apply the unfolded force to the clamping column 303, thereby increasing the clamping force of the clamping column 303 on the rubber plate 402. In this way, even small copper wires will be clamped down, and there will be no phenomenon of slight pulling separating them from the clamping column 303.
[0035] Furthermore, when the push plate 7 moves upward, the inner wall of the limiting port will press against the inclined surface of the limiting block 502, thereby pushing the limiting block 502 into the inside of the pushing groove. The reset spring 503 will be compressed. After the limiting block 502 passes through the limiting port, the reset spring 503 will unfold. In this way, the limiting block 502 can be reset under the push of the reset spring 503, thereby fixing the position of the push plate 7. This completes the adjustment of the clamping force of the rubber plate 402 and the clamping column 303 according to the size of the copper wire.
[0036] When the rubber plate 402 needs to be replaced due to friction caused by the removal of the copper wire, simply pull the limiting plate 401 out of the push plate 7. Replacement is also simple: just insert the new limiting plate 401 and the limiting strip 8 into the push plate 7.
[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
