[0004] However, the above utility model patent has the following technical problems in actual use:

[0005] 1. The above-mentioned device is used to place bolts by opening a placement groove along the length of the top of the support seat, but the length of the placement groove is fixed and cannot be adjusted. When the length of the bolt to be tested placed in the placement groove is consistent with the length of the placement groove (or close to the length of the placement groove), it will cause blockage of the internal space of the placement groove, resulting in the inability to manually reach into the placement groove to grab the bolt when taking the bolt later, affecting the actual use of the above-mentioned device.

[0006] Second, when inspecting the bolts, it is also necessary to inspect their curvature. The above device lacks a mechanism for inspecting the curvature of the bolt surface, so the curvature of the bolt surface cannot be inspected by the above device. Utility Model Content

[0007] The utility model provides a metal connecting piece detection device, aiming to solve the problem mentioned in the above-mentioned background technology that when the length of the bolt placed in the placement slot is close to or equal to the length of the placement slot, it will occupy the space in the placement slot, resulting in the inability to manually reach into the placement slot to grab the bolt during subsequent picking. External auxiliary equipment may be required, which greatly reduces the actual use function of the above-mentioned device. At the same time, the above-mentioned device also lacks a mechanism for detecting the curvature of the bolt surface.

[0008] The utility model is implemented in this way. A metal connector detection device comprises: a detection platform, which has: a placement block and a movable seat arranged on one side of the placement block, a placement groove is opened on the top wall of the placement block, and the placement groove is connected to the side wall of the placement block close to the side of the movable seat, an adjustment component is arranged on the side wall of the placement block and is movably connected to the movable seat, and the adjustment component is used to control the movable seat to approach / move away from the placement block, and a detection mechanism, which has: a length detection component arranged on the movable seat and a curvature detection component slidably connected to the placement groove, and the length detection component and the movable seat are connected to the side wall of the placement block. The curvature detection component is used to respectively detect the length and curvature of the workpiece in the placement slot; in this scheme, the device can control the movable seat to approach or move away from the placement block through the adjustment component. When the length of the bolt placed in the placement slot is too long and equal to or close to the length of the placement slot, it is difficult for humans to easily remove the bolt from the placement slot. At this time, it is only necessary to pull the movable seat in the direction away from the placement block, so that the movable seat is separated from the blockage of the end of the placement slot. Humans can grab one end of the bolt from the side of the placement slot and easily remove it from the placement slot, which greatly reduces the difficulty of manually taking the bolt. At the same time, there is no need to use external tools, which reduces the manual workload.

[0016] 1. The device can control the movable seat to be close to or away from the placement block through the adjustment component. When the length of the bolt placed in the placement slot is too long and equal to or close to the length of the placement slot, it is difficult for humans to easily remove the bolt from the placement slot. At this time, it is only necessary to pull the movable seat in the direction away from the placement block, so that the movable seat is separated from the blockage of the end of the placement slot. Humans can grab one end of the bolt from the side of the placement slot and easily remove it from the placement slot, which greatly reduces the difficulty of manually taking the bolt. At the same time, there is no need to use external tools, which reduces the workload of humans.

[0017] 2. This device can detect the flatness of the screw surface by sliding a curvature detection component in the placement slot, wherein when the bolt is placed in the placement slot, one end thereof passes through a through hole opened on the side wall of the sliding block (the aperture of the through hole matches the outer diameter of the bolt to be detected), and abuts against the inner wall of the placement slot away from the movable seat, and the other end abuts against the support plate. While detecting the length of the bolt, the sliding block slides horizontally between the support plate and the inner wall of the placement slot, thereby utilizing the through hole to detect the flatness of the bolt surface.
