Technical Field

[0001] This utility model belongs to the technical field of multi-station laminators for latex product preparation, and in particular relates to a rotary multi-station product defect detection device. Background Technology

[0002] The rotary table multi-station product defect detection device is a high-precision, high-efficiency automated optical inspection equipment. It achieves full-surface quality screening of complex workpieces by working in collaboration with multiple cameras / sensors through a rotating worktable.

[0003] Traditional rotary multi-station product defect detection devices typically install multiple product clamps on the turntable to hold and fix the products to be inspected, thereby maintaining stability during rotation. However, this method increases the number of parts and significantly increases costs. Furthermore, when picking up or putting down products, it is necessary to clamp or unclamp the clamps, which consumes a lot of time and reduces the efficiency of product inspection. Utility Model Content

[0004] The purpose of this invention is to provide a rotary multi-station product defect detection device. By setting a placement mold, specifically by inserting the placement mold into the positioning shaft on the connecting plate through a positioning hole, and then locking the placement mold in place using a nut connected to the threaded shaft, the positioning protrusions on the placement mold are used to position and stably place the compatible product. This allows for rapid product handling during the detection process, and the placement mold can be replaced for different products, thus meeting various product detection needs. This method is simple and convenient in structure, reduces operating costs, and solves the problem that traditional rotary multi-station product defect detection devices typically install multiple product clamps on the turntable to hold and fix the products to be detected, which increases the number of parts and significantly increases costs.

The placement mold 23 is then... The positioning hole 231 is positioned and inserted into the positioning shaft 223 on the connecting plate 221. Then, the nut is used to connect with the threaded shaft 222 to lock and fix the placement mold 23. The positioning protrusion 232 on the placement mold 23 is used to position and stably place the matching product 24, so that the product 24 can be quickly picked up and put down during the inspection process. The placement mold 23 can be replaced for different products 24 to meet the inspection needs of various products 24. This method has a simple and convenient structure and reduces the cost of use. The threaded shaft 222 is inserted into the center of the placement mold 23. The nut installed on the threaded shaft 222 is used to fix the placement mold 23 on the connecting plate 221. The positioning protrusion 232 is used to position the product 24.

[0028] The placement mold 23 is positioned and inserted into the positioning shaft 223 through the positioning hole 231. The center of the top of the placement mold 23 is set with a round hole. After the nut is installed on the threaded shaft 222, the nut is located in the round hole on the placement mold 23.

[0029] Both the top of the column 11 and the left side of the detection base 1 are equipped with detection mechanisms 3. The detection mechanism 3 located at the top includes a top plate 31 fixedly connected to the top of the column 11. An electric push rod 32 is fixedly connected to the top plate 31. An industrial camera 33 is fixedly connected to the output end of the electric push rod 32 through a flange. A supplementary light 34 is set below the industrial camera 33. A bracket 35 is fixedly connected to the top of the supplementary light 34. The left side of the bracket 35 is fixedly connected to the surface of the column 11. The rotary table 21 drives the product 24 to rotate and adjust its position in sequence. The industrial camera 33 at the top will capture images of the top of the product 24, while the industrial camera 33 on the left will capture images of the side of the product 24. The stepper motor 22 drives the connecting plate 221 to rotate slowly and rotate together with the product 24, thereby capturing images of the product 24 from multiple angles and improving the detection effect.

[0030] A gear ring 211 is fixedly connected to the center of the bottom of the rotary turntable 21. Several inner ball sliders 212 are fixedly connected to the bottom of the rotary turntable 21. An annular rail 213 is slidably connected inside the inner ball sliders 212. The bottom of the annular rail 213 is fixedly connected to the top of the detection seat 1.

[0031] The output end of stepper motor 12 is fixedly connected to gear 121 by a pin and a retaining ring. Gear 121 meshes with gear ring 211. There is a gap between the bottom of stepper motor 22 and the top of detection seat 1, and a gap between the bottom of gear ring 211 and the top of detection seat 1.

[0032] One specific application of this embodiment is:

[0033] In use, first install multiple placement molds 23 on the rotary table 21, and then position and insert the placement molds 23 into the positioning shaft 223 on the connecting plate 221 through the positioning hole 231. The threaded shaft 222 will be inserted into the placement mold 23. Then, use a nut to connect with the threaded shaft 222 to lock and fix the placement mold 23. At this time, the placement mold 23 is fixed. The positioning protrusion 232 on the placement mold 23 is used to position and stably place the matching product 24, so that the product 24 can be quickly picked up and put down during the inspection process. When different products 24 need to be inspected, remove the nut on the threaded shaft 222 to release the fixation of the placement mold 23. The placement mold 23 can then be disassembled and replaced with a placement mold 23 that is suitable for different products 24 to meet the inspection needs of multiple products 24.

[0034] Once the products 24 are placed on the rotary table 21, the stepper motor 12 is started to drive the gear 121 to rotate. The gear 121 then drives the rotary table 21 to rotate through the gear ring 211. At this time, the inner ball slider 212 slides on the ring rail 213, making the rotary table 21 rotate more stably and smoothly. In conjunction with the encoder, the rotary table 21 rotates at a fixed angle, ensuring that the products 24 are aligned with the detection mechanism 3 with each rotation, thus performing the detection work. When the products 24 move to the bottom of the industrial camera 33 above, the industrial camera 33 will detect the top of the products 24. The supplementary light 34 will provide supplementary light to the products 24 to improve the detection effect. At the same time, the electric push rod 32 will drive the industrial camera 33 to move up and down, which can be adjusted to a suitable position according to the size of the products 24. The industrial camera 33 integrates encoders, PLCs and other devices to achieve synchronous triggering and dynamic adjustment. Through image acquisition, it identifies defects such as scratches and wrinkles on the surface texture features of the products 24.

[0035] After the top of product 24 is inspected and rotated to the position of industrial camera 33 on the left by rotary table 21, stepper motor 22 is started to drive connecting plate 221 to rotate slowly. The mold 23 will rotate together with product 24. Industrial camera 33 on the left will then capture and inspect the side of product 24. At the same time, electric push rod 32 on the left can move and adjust the position of industrial camera 33 to adapt to different products 24. Finally, product 24 that has been inspected will rotate to the front position, and the staff can take out product 24 and replace it.

[0036] It should be noted that the control of the rotating mechanism 2 and the detection mechanism 3 in this application can both be achieved by using a program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.
