Description

Technical Field

[0001] The utility model relates to the technical field of food and drug packaging, and particularly relates to a lamp inspection machine tracking device. Background Art

[0002] In the production process of lamp inspection machine products, the camera tracking mechanism is particularly important. If the tracking is unstable, it will affect the camera detection and further affect the detection effect of the entire device. The existing tracking mechanism uses the method of gear and rack to drive the tracking mechanism to reciprocate for tracking movement. After using the gear and rack tracking for a period of time, the gear will be worn, resulting in too large a gear clearance and further affecting the detection effect. Moreover, during the reciprocating movement process, the driving motor needs to rotate forward and reverse repeatedly, with a high load and a short service life. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a lamp inspection machine tracking device with a simple structure, in which the driving motor does not need to rotate forward and reverse repeatedly and has little wear.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme:

[0005] A lamp inspection machine tracking device includes a swing frame rotatably arranged on a turntable fixing frame. A detection mechanism is arranged on the swing frame. The device further includes a driving wheel and a rotation drive for driving the driving wheel to rotate. One side of the driving wheel on the central axis is hinged with a link mechanism, and the other end of the link mechanism is hinged with a swing arm. The swing frame is connected with the swing arm.

[0006] As a further improvement of the above technical scheme:

[0007] An eccentric shaft is arranged on one side of the driving wheel on the central axis, and the link mechanism is hinged with the eccentric shaft through a first bearing.

[0008] The link mechanism includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged with the eccentric shaft, and the other end is connected with the second connecting rod. The other end of the second connecting rod is hinged with the swing arm, and the total length of the first connecting rod and the second connecting rod is adjustable.

[0009] A kidney-shaped hole is arranged on the first connecting rod, and a connecting hole is arranged on the second connecting rod. The connecting hole is locked with the kidney-shaped hole through a locking piece.

[0010] The locking piece is a locking bolt.

[0011] A connecting rotating shaft is arranged on the second connecting rod, and the swing arm is hinged with the connecting rotating shaft through a second bearing.

[0012] A fixing seat is detachably connected to the swing arm, and the fixing seat is hinged with the link mechanism.

[0013] The rotational drive is a rotary motor.

[0014] The rotary motor is connected with a speed reducer, and the speed reducer is connected with the central shaft of the driving wheel.

[0015] The inspection machine tracking device further includes a motor mounting base arranged on the bottom surface, the speed reducer is arranged on the mounting base, and the driving wheel is located below the mounting base.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] In the inspection machine tracking device disclosed by the present utility model, the rotational drive drives the driving wheel to rotate, thereby driving the link mechanism to swing reciprocally, and finally driving the swing arm to swing reciprocally. Since the swing frame is connected to the swing arm, the swing frame is driven to swing reciprocally on the turntable fixing frame, and the inspection mechanism on the swing frame can realize tracking and inspecting the bottle body. In this drive structure, the link mechanism is hinged on one side of the central shaft of the driving wheel. The driving wheel only needs to move in one direction to drive the swing frame to swing reciprocally on the turntable fixing frame. Compared with the drive structure using a gear and rack, the wear is smaller, the service life is longer, and the stability is also better, improving the inspection effect of the inspection mechanism.
