Description
Technical Field
[0001] This utility model relates to the field of visual inspection and sorting technology, and in particular to a visual inspection and sorting device for blister packaging products. Background Technology
[0002] Vacuum-formed products are mostly thin and light plastic molded parts, such as trays and packaging boxes. The surface is prone to minor defects such as scratches, damage, and bubbles. Moreover, the dimensional accuracy has a significant impact on subsequent use. However, visual inspection and sorting equipment can accurately measure dimensions through high-precision imaging and algorithms. Its automated sorting function can be synchronized with the production line, processing dozens to hundreds of products per minute, which greatly improves efficiency.
[0003] Some existing vision inspection and sorting equipment delivers blister products to the inspection area via a conveyor belt. The industrial camera of the vision system captures images, and the algorithm identifies defects, dimensional deviations, etc. Based on the inspection results, the control system drives the sorting mechanism to remove unqualified products, while qualified products continue to be conveyed. The entire process is synchronized through sensor linkage, which is suitable for high-speed production.
[0004] In the operation of some existing visual inspection and sorting equipment, the visual inspection system is easily affected by fluctuations in the intensity of external light. When the external light is too strong, it is easy to form reflections on the surface of the thermoformed products, which can cover up minor defects. When the light is too weak or uneven, it will lead to a decrease in image contrast, which will reduce the accuracy of dimensional measurement and increase the rate of missed defect detection. Therefore, a visual inspection and sorting equipment for thermoformed products is proposed to solve the above problems. Utility Model Content

As a further description of the above technical solution: The positioning mechanism for the thermoformed product includes a horizontal support plate b, the bottom of which is fixedly connected to the top of the support rod, and a cylinder b is fixedly connected to the top of the horizontal support plate b. As a further description of the above technical solution: The piston rod b is fixedly connected to the drive end of the cylinder b.

This ensures that the blister product is in the best inspection field of the vision inspection instrument, avoids it from shifting or shaking during the inspection process, improves the positioning accuracy, and ensures the smooth progress of the inspection work.

The left side of the rotating rod a32 is rotatably connected to a connecting plate a33. The top of the support frame 2 is fixedly connected to multiple connecting plates a33. Two connecting plates a33 are rotatably connected to a rotating rod c36 on the adjacent side of two connecting plates a33. The outer top of the rotating rod b34 is rotatably connected to two connecting plates b35. The top of the connecting plate b35 is fixedly connected to a light-shielding plate 37. Driven by the rotating rod a32, the rotating rod b34 can swing around the connection point with the connecting plate a33, thereby driving the connecting plate b35 and the rotating rod c36 to move, and transmitting power to the light-shielding plate 37. The drive assembly 31 includes a motor 311, which provides stable and precise power input to the light shield 37. The bottom of the motor 311 is fixedly connected to the top of the support frame 2. The drive end of the motor 311 is fixedly connected to a rotating shaft a312. An eccentric turntable 313 is fixedly connected to the left side of the rotating shaft a312.

The outer top end of the rotating rod c36 is rotatably connected to the adjacent side of the two connecting plates b35.
[0013] Reference Figure 1 , Figure 2 , Figure 4The thermoforming product positioning mechanism 10 includes a horizontal support plate b101. The bottom of the horizontal support plate b101 is fixedly connected to the top of the support rod 9. A cylinder b102 is fixedly connected to the top of the horizontal support plate b101. A piston rod b103 is fixedly connected to the driving end of the cylinder b102. The cylinder b102 drives the piston rod b103 to perform linear reciprocating motion.

Under the push of telescopic rod 1010, L-shaped rotating plate 1011 swings around the connection point with clamping disc 1012, converting the thrust of telescopic rod 1010 into the clamping force of clamping disc 1012.
[0014] Reference Figure 1 , Figure 2 The bottom of the support body 1 is fixedly connected with multiple support feet 8, which support the weight of the entire equipment and isolate the support body 1 from the ground. The rear side of the support body 1 is fixedly connected with a collection cylinder 11, which serves as a collection device for defective blister products and removes and collects defective products. The support body 1 is fitted with a conveyor belt 12, which transports the blister products to be inspected from the equipment entrance to the inspection area of the blister product positioning mechanism 10 and the visual inspection instrument 7. After the inspection is completed, the qualified products are transported to the next process.
[0015] Working principle: First, the blister product is placed on the conveyor belt 12. The conveyor belt 12 transports the blister product to the working area of the blister product positioning mechanism 10. The cylinder b102 is activated, driving the piston rod b103 to move the slider 104 along the limiting plate 108. The rotating rod e106 is fixed by the rotating shaft b107. The movement of the right slider 104 drives the right rotating rod d105 to move, which in turn drives the left rotating rod d105 to move, which in turn drives the two sliders 104 to move inward. Through the telescopic rod 1010, the L-shaped rotating plate 1011 is pushed. The L-shaped rotating plate 1011 drives the two clamping plates 1012 to move, clamping and positioning the blister product. After positioning is completed, if the lighting is poor or strong, the motor 311 is started to drive the rotating shaft a312 to rotate, which in turn drives the eccentric turntable 313 to rotate, which in turn drives the rotating rod a32 to rotate, which in turn drives the rotating rod b34 to rotate. The rotating rod c36 restricts the movement trajectory of the light shield 37 and rotates synchronously with the rotating rod b34, causing the light shield 37 to retract or open, controlling the influence of external light intensity on the visual inspection instrument 7 and avoiding interference from external light. After the inspection is completed, if the thermoformed product is qualified, the product continues to be conveyed with the conveyor belt 12; if the product is unqualified, the cylinder a5 on the horizontal support plate a4 is activated, and the piston rod a6 pushes the unqualified product into the collection cylinder 11.
