Description

Technical Field

[0001] The present invention relates to the field of light inspection machines, and in particular to a lifting and rotating mechanism for appearance inspection. Background Art

[0002] Currently in the field of pharmaceutical and food packaging machinery, light inspection machines are used to detect the appearance of filled bottles or foreign objects in the bottles. They use optical imaging and computer analysis of the collected image data to judge the filled finished bottles and automatically remove unqualified products.

[0003] Existing optical inspection machines, such as the Chinese patent document with the publication number CN114345738A, are named "Structure in optical inspection machine". However, the positioning of the product in the above-mentioned optical inspection machine is to place it in the sink groove of the rotating base in the main tower turntable, and then the lower pressure rod installed on the bottle pressing turntable is pressed down to abut against the top of the product. This method can only inspect the product on the vertical side, but the part in the sink groove cannot be inspected, such as the bottom rounded corner of the product, so there is a risk of missing defects. Summary of the Invention

[0004] In order to improve the adequacy of product inspection and thus improve the inspection effect, the present application provides a lifting and rotating mechanism for appearance inspection.

[0005] This application provides a lifting and rotating mechanism for appearance inspection, which adopts the following technical solutions:

[0006] A lifting and rotating mechanism for appearance inspection includes a base for installation on a main tower turntable and a bottle pressing rod for installation on a bottle pressing turntable, the base and the bottle pressing rod are arranged opposite to each other, and a sink groove is provided at one end of the base close to the bottle pressing rod. An inner support rod is slidably installed in the base in a direction close to or away from the bottle pressing rod, and the top end of the inner support rod extends to the bottom of the sink groove; the lifting and rotating mechanism also includes a driving assembly for driving the base and the inner support rod to rotate synchronously, and a driving member for driving the inner support rod to slide.

[0007] By adopting the above technical solution, the bottom of the product is inserted into the sink groove of the base, and the product is centered by the bottle pressing rod, and then the stable transportation of the product is achieved by the synchronous rotation of the main tower turntable and the bottle pressing turntable. At this time, the bottom rounded corner position of the product is blocked; when the product is transported to the detection position, the base and the inner support rod are first driven to rotate by the driving component, and then the product is driven to rotate, and the horizontal shooting camera performs full-circle shooting and detection of the vertical surface of the product; then the driving part drives the inner support rod to slide in the direction close to the bottle pressing rod, which can push the product to lift, so that the bottom of the product leaves the sink groove, and at the same time, the driving component drives the inner support rod to rotate, and the rounded corner camera performs full-circle shooting and detection of the bottom rounded corner of the product; the above process can complete the detection of the bottom rounded corner of the product inserted into the sink groove, thereby improving the adequacy of product detection and thus improving the detection effect.

[0011] By adopting the above technical solution, when the outer seat and the inner support rod rotate together with the main tower turntable, the guide seat is lifted by the guiding inclined surface of the boss, thereby driving the inner support rod to be lifted, so as to drive the bottom of the product out of the sink; and when the guide seat leaves the boss, it can be reset together with the inner support rod by its own gravity; this process only requires driving the inner support rod to slide during the rotation of the main tower turntable, without the need for additional power source, thus reducing costs.

[0012] Preferably, a plurality of guide rods are provided between the guide seat and the outer sleeve seat, and the plurality of guide rods are arranged along the circumferential direction. One end of the guide rod is fixedly mounted on the guide seat, and the other end is slidably mounted on the outer sleeve seat in the sliding direction of the inner support rod.

[0013] By adopting the above technical solution, in the process of driving the guide seat to lift, the guide rod slides in the outer sleeve seat, thereby playing a guiding role, thereby making the lifting and sliding of the inner support rod more stable.

[0014] Preferably, the driving assembly includes a driving pulley, a driven pulley, a belt and a driving member, the driving pulley is used to be rotatably mounted on the main tower turntable, the driven pulley is sleeved on the outer sleeve seat, and the belt is simultaneously wound around the driving pulley and the driven pulley; the driving member is used to drive the driving pulley to rotate.

[0015] By adopting the above technical solution, the driving part is started, and the outer sleeve is driven to rotate through the belt transmission method, thereby driving the base to rotate; and due to the action of the guide rod, the outer sleeve can drive the inner support rod to rotate at the same time as it rotates, without the need for an additional power source, further reducing costs.

[0016] Preferably, a ball is installed on the end portion of the guide seat away from the outer sleeve seat.

[0017] By adopting the above technical solution, the friction is reduced during the movement of the guide seat on the boss, making the process smoother.

[0018] Preferably, an elastic member is sleeved on one end of the inner support rod close to the outer sleeve seat, and two ends of the elastic member are respectively connected to the outer sleeve seat and the guide seat.

[0019] By adopting the above technical solution, when the guide seat leaves the boss and needs to be reset, the elastic action of the elastic member enables the guide seat to complete the reset more stably.

[0020] Preferably, a pressing head is rotatably mounted on one end of the bottle pressing rod close to the base.

[0021] By adopting the above technical solution, the bottle pressing rod and the pressing head together position the center of the product. When the base and the inner support rod rotate to drive the product to rotate, the pressing head can also rotate, thereby improving the smoothness of the product rotation.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. When the product is conveyed to the inspection position, the drive assembly first drives the base and inner support rod to rotate, thereby driving the product to rotate, and the horizontal camera takes a full-circle photograph of the vertical surface of the product for inspection. Then, the drive member drives the inner support rod to slide toward the bottle pressing rod, which can push the product up, so that the bottom of the product leaves the sink. At the same time, the drive assembly drives the inner support rod to rotate, and the rounded corner camera takes a full-circle photograph of the bottom rounded corners of the product. The above process can complete the inspection of the bottom rounded corners of the product stuck in the sink, improving the comprehensiveness of product inspection and thus improving the inspection effect.
