[0004] The above patent has some advantages, but also has some problems, such as: since a lot of debris will be generated when the screw is processed by the thread rolling machine, the above patent cannot process these debris before testing. Summary of the invention

[0005] In view of the problems mentioned in the background technology, an object of the present invention is to provide a multi-station thread rolling machine detector to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A multi-station thread rolling machine detector comprises a frame, a servo motor is fixed on the frame, a support rod is fixed to the end of the motor shaft of the servo motor, a box body which can slide horizontally is arranged above the frame, the top of the box body is an inclined surface, a screen is detachably connected to the top of the box body, and side baffles are fixed on both sides of the screen; a first wheel disc and a second wheel disc are fixed to the outside of the support rod; the first wheel disc drives the box body and the screen to shake as a whole through a first linkage assembly, and shakes the slag particles on the surface of the screws processed by the thread rolling machine into the box body; a horizontally sliding end baffle is arranged at the end of the screen, and the second wheel disc drives the end baffle to slide horizontally through a second linkage assembly and controls the screws above the screen to fall from the side of the screen close to the end baffle, and the frame is provided with a detection platform at the end side of the screen, and a visual camera is installed above the detection platform.

[0008] By adopting the above technical scheme, the device can be used to remove surface slag particles from the screws to be inspected, thereby improving the inspection effect; the screen in the multi-station thread rolling machine detector is used to receive the screws processed by the thread rolling machine. After the screws fall on the screen, they can be driven by the first wheel driven by the servo motor to shake through the first linkage assembly, so that the slag particles on the surface of the screws are vibrated and fall into the box body. Since an end baffle is provided at the end of the screen, when a certain number of screws accumulate above the screen and need to be transferred to the inspection table for inspection, the position of the end baffle can be controlled to control the screws to fall. Since the servo motor can also drive the second wheel to rotate, when the second wheel rotates, the end baffle can be driven to slide through the second linkage assembly, thereby controlling the screws to fall.

[0020] By adopting the above technical solution, the placement box can be used to assist workers in collecting the inspected screws in the placement box.

[0021] Preferably, a controller is fixed on the frame, a control input end of the controller is electrically connected to the servo motor, the micro motor, and the visual camera, and a control output end of the controller is electrically connected to an alarm.

[0022] By adopting the above technical solution, the servo motor, the servo motor and the visual camera can be controlled by the controller.
