Description

Technical Field

[0001] The utility model relates to the fields of connectors and wire harness manufacturing, and particularly relates to a low-voltage wire pin-removing detection device. Background Art

[0002] With the popularization and promotion of new energy vehicles, the use of automotive connectors has been gradually increasing, and the processing and manufacturing requirements of connectors have been gradually improved. Most of the new energy connectors are equipped with low-voltage wires.

[0003] The existing detection method is to manually pull back the low-voltage wire to detect whether the low-voltage wire is inserted in place. Such an operation method has low efficiency and poor product detection consistency. There is also a phenomenon that manual workers may miss the back-pulling detection. Moreover, when the wire skin is smooth, the hand slips when pulling back the low-voltage wire, resulting in inaccurate detection, which cannot meet the increasing production capacity requirements of the demand side.

[0004] Therefore, aiming at the problem that the existing detection method is to manually pull back the low-voltage wire to detect whether the low-voltage wire is inserted in place, and such an operation method has low efficiency and poor product detection consistency, it is urgently needed to be solved to improve the use scenario of the low-voltage wire pin-removing detection device. Summary of the Utility Model

[0005] In order to overcome the problems of common detection devices, that is, manually pulling back the low-voltage wire by hand to detect whether the low-voltage wire is inserted in place, such an operation method has low efficiency and poor product detection consistency, and it is easy to slip when detecting a low-voltage wire with a smooth wire skin.

[0006] The technical solution of the utility model is: a low-voltage wire pin-removing detection device, which includes a bottom plate. A connection component is installed on the left side of the upper surface of the bottom plate. A clamping component is arranged on the right side of the connection component. A stretching component is installed in the middle section of the upper surface of the bottom plate. The clamping component is installed on the front surface of the stretching component.

[0007] Preferably, the connection component can facilitate the positioning of the low-voltage wire, and the clamping component can clamp the low-voltage wire. At the same time, the clamping force can be adjusted to provide protection for the wire harness, and cooperate with the stretching component to complete the detection of the wire harness, replacing the manual pulling method, and improving the detection accuracy and detection efficiency.

[0008] As a preference, the connection component includes a product seat and a placement groove. The product seat is installed on the left side of the upper surface of the bottom plate. A placement groove is opened on the top surface of the product seat. The connection component as a whole adopts a profiling design. By setting the placement groove, auxiliary limit can be provided for the wire harness to avoid deviation during stretching and affecting the detection result. The profiling design can prevent similar products from being mixed in the products of the same batch.

[0009] Preferably, the clamping assembly includes a base, a broadcaster, a cylinder guide rail, a moving seat and a jaw; the upper surface of the base plate is provided with a base, the outer surface of the base is provided with a broadcaster, and the top surface of the base is provided with a cylinder guide rail. The inside of the cylinder guide rail is slidably connected with symmetrically arranged moving seats, and the inner surface of the moving seat is provided with jaws. By controlling the cylinder guide rail to make the moving seats approach each other, the two jaws can be driven to fit together, thus completing the clamping of the wire harness. At the same time, the clamping force can be adjusted by controlling the internal pressure of the cylinder guide rail to reduce the damage to the wire skin. If there is no phenomenon of low-voltage wire PIN withdrawal, the broadcaster will announce it as qualified. If a certain low-voltage wire is pulled out, the broadcaster will announce it as unqualified.

[0010] Preferably, the jaws adopt a staggered clamping design, which can make the entire circumference of the low-voltage wire be on the contact stress surface of the jaws, and at the same time avoid unilateral stress from pinching and pulling the wire harness outer skin.

[0011] Preferably, the stretching assembly includes a cylinder and a mounting plate; the upper surface of the base plate is provided with a cylinder, the telescopic end of the cylinder is provided with a mounting plate, and the clamping assembly is mounted on the side surface of the mounting plate close to the cylinder. By the operation of the cylinder, the clamping assembly can be driven to pull back, thus replacing the manual pulling method, with higher precision. And by controlling the internal pressure of the cylinder, the pulling-back force can be accurately controlled to ensure the consistency of the pulling-back force of each low-voltage wire.

[0012] Preferably, there are two sets of symmetrically arranged clamping assemblies and stretching assemblies. An installation hole is opened in the middle of the upper surface of the base plate between the clamping assembly and the stretching assembly, and a wire dividing column is installed inside the installation hole. By setting the wire dividing column, the low-voltage wires of the product can be divided, guided and positioned, preventing the low-voltage wires from deviating from the range of the jaws. And by setting two sets of symmetric clamping assemblies and stretching assemblies, two wire harnesses can be detected simultaneously, improving the detection efficiency.

[0013] Preferably, symmetrically arranged screw holes are penetrated through the upper surface of the base plate at the bottom of the connecting assembly, and adjusting screws are arranged inside the screw holes. By changing the protruding height of the adjusting screws, the coaxiality of the product seat and the clamping of the jaws can be quickly adjusted to ensure the consistency of product detection.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. By setting the connecting assembly, it is convenient to position the low-voltage wire. And through the clamping assembly, the low-voltage wire can be clamped, and at the same time, the clamping force can be adjusted to provide protection for the wire harness. It cooperates with the stretching assembly to complete the detection of the wire harness, replacing the manual hand-pulling method, improving the detection accuracy and detection efficiency;

[0016] 2. By setting the jaws with a misaligned clamping design, the entire circumference of the low-voltage wire can be on the contact stress surface of the jaws. At the same time, it also avoids pinching and pulling the outer skin of the wire due to unilateral stress. And through the operation of the air cylinder, the clamping component can be driven to retract, thus replacing the manual retraction method, with higher precision. And by controlling the internal pressure of the air cylinder, the retraction force can be accurately controlled to ensure the consistency of the retraction force of each low-voltage wire.

And the clamping component 3 includes a base 301, a broadcaster 302, a cylinder guide rail 303, a moving seat 304 and a clamping jaw 305; the base 301 is installed on the upper surface of the bottom plate 1, the broadcaster 302 is arranged on the outer surface of the base 301, and the cylinder guide rail 303 is installed on the top surface of the base 301. The symmetrically arranged moving seats 304 are slidably connected inside the cylinder guide rail 303, and the clamping jaws 305 are installed on the inner surfaces of the moving seats 304. By controlling the cylinder guide rail 303 to make the moving seats 304 approach each other, the two clamping jaws 305 can be driven to fit together, thus completing the clamping of the wire harness. At the same time, by controlling the internal pressure of the cylinder guide rail 303, the clamping force can be adjusted to reduce the damage to the wire sheath.
