Description

Technical Field

[0001] This utility model relates to the field of medical piston technology, and in particular to a piston surface defect detection device. Background Technology

[0002] The medical injection rubber piston is a key component of the syringe, typically made of medical-grade rubber material. It possesses excellent sealing properties, chemical stability, and biocompatibility. Its core function is to ensure the syringe remains sealed during drug aspiration and injection, preventing leakage or external contamination. Simultaneously, the rubber piston must possess a certain degree of elasticity and lubrication, allowing it to fit tightly against the syringe wall while maintaining smooth sliding to reduce operational resistance for healthcare workers.

[0003] In existing technologies, when inspecting pistons, the pistons are placed on the surface of the conveyor belt. Since the pistons cannot be evenly arranged, the inspection system may not be able to quickly locate the pistons for scanning. This causes the inspection system to repeatedly scan invalid areas, increasing the power consumption of the inspection system, potentially causing the inspection system to miss detections, and reducing the reliability of the entire batch of products. Summary of the Invention

[0004] The problem to be solved by this utility model is to provide a piston surface defect detection device, which addresses the shortcomings of the prior art.

[0005] To solve the above problems, the present invention adopts the following solution: a piston surface defect detection device, comprising a transmission detection mechanism, a separation mechanism, and a rejection mechanism, wherein the separation mechanism is located inside the transmission detection mechanism, and the rejection mechanism is located inside the transmission detection mechanism;

[0006] The transmission detection mechanism includes a support frame, a transmission device is installed inside the support frame, a top plate is fixedly connected to the top of the support frame, a vision detection device is fixedly connected inside the transmission device, a support frame is fixedly connected to the outer wall of the support frame, a rotating rod is rotatably connected inside the support frame, an adjusting plate is fixedly connected to the bottom of the rotating rod, a limit post is fixedly connected to the outer wall of the end of the rotating rod away from the adjusting plate, a worm gear is fixedly connected to the outer wall of the end of the rotating rod near the limit post, a worm gear is meshed with a worm, a handle is fixedly connected to the outer end of the worm, a connecting block is rotatably connected to the outer wall of the worm, and the connecting block is fixedly connected to the outer wall of the support frame.

[0007] With the above technical solution, after the piston is placed on the surface of the transmission device, it is restricted by the adjusting plate, causing the piston to move uniformly towards the center of the transmission device, thus arranging the pistons in a straight line. A top plate is fixed on the top of the support, and a vision inspection device is fixed inside the top plate. When the piston reaches the bottom of the vision inspection device, it is inspected by the vision inspection device to determine the integrity of the piston. The uniform arrangement improves the detection efficiency of the vision inspection device, avoids missed scans, reduces the possibility of missed judgments, and improves the reliability of piston quality. The operator drives the worm gear to rotate by the handle. When the worm gear meshes with the worm wheel, the adjusting plate is adjusted at a certain angle around the rotating rod, so that pistons of different sizes can be inspected, improving the overall flexibility of the equipment.

[0008] As a further improvement to the above solution, the separating mechanism includes a fixed plate, which is fixedly connected to the outer wall of the bracket, and a sliding rod is slidably connected inside the fixed plate.

[0009] As a further improvement to the above solution, a baffle is fixedly connected to the outer wall of the sliding rod, a cylinder is fixedly connected to the end of the sliding rod away from the baffle, and a support frame is fixedly connected to the outer wall of the cylinder.

[0010] As a further improvement to the above solution, the support frame is fixedly connected to the bottom of the fixed plate, and a guide rod is slidably connected inside the end of the baffle away from the sliding rod, and the guide rod is fixedly connected to the bottom of the top plate.

[0011] Through the above technical solution, the cylinder drives the baffle to move through the sliding rod. At the same time, the baffle slides on the outer wall of the guide rod, so that the baffle can be raised and lowered vertically, thereby controlling the distance between each piston, ensuring that the vision inspection device can detect evenly, and improving the smoothness of the overall operation.

[0012] As a further improvement to the above solution, the rejection mechanism includes a fixing plate, which is fixedly connected to the outer wall of the support, and a support plate is fixedly connected to the outer wall of the fixing plate.

[0013] As a further improvement to the above solution, a cylinder is fixedly connected to the bottom of the support plate, a push block is fixedly connected to the output end of the cylinder, and a fixing block is fixedly connected to the top of the push block.

[0014] As a further improvement to the above solution, a support rod is slidably connected inside the fixing block, and the support rod is fixedly connected to an outer wall of the fixing plate.

[0015] With the above technical solution, when the vision inspection device detects a defective piston, it sends an electrical signal to cylinder one. When cylinder one receives the command and starts running, it pushes the push block. At the same time, the output end of cylinder one slides through the fixed plate, and the push block is fixed to the fixed plate. A sliding support rod slides inside the fixed plate, ensuring that the push block moves in a straight line. This quickly removes defective products from the surface of the conveying device, and the defective products fall into the collection box, making it convenient for personnel to collect them. By reducing the frequency of manual intervention in production, the equipment can operate continuously, reducing downtime and improving overall production efficiency.

[0016] The technical effects of this utility model are as follows: After the piston is placed on the surface of the transmission device, it is restricted by the adjusting plate, causing the piston to move uniformly towards the center of the transmission device, thus arranging the pistons in a straight line. A top plate is fixed on the top of the support, and a vision inspection device is fixed inside the top plate. When the piston reaches the bottom of the vision inspection device, the integrity of the piston is determined by the vision inspection device. The uniform arrangement improves the detection efficiency of the vision inspection device, avoids missed scans, reduces the possibility of missed judgments, and improves the reliability of piston quality. The operator drives the worm gear to rotate by the handle. When the worm gear meshes with the worm wheel, the adjusting plate is adjusted at a certain angle around the rotating rod, thereby enabling the inspection of pistons of different sizes and improving the overall flexibility of the equipment.

[0017] This invention utilizes a visual inspection device to send an electrical signal to cylinder one when a defective piston is detected. Upon receiving the signal and starting operation, cylinder one pushes a push block. Simultaneously, the output end of cylinder one slides through a fixed plate, fixing the push block to the fixed plate. A sliding support rod inside the fixed plate ensures the push block moves linearly, quickly removing defective products from the surface of the conveying device. The defective products fall into a collection box for easy collection. By reducing the frequency of manual intervention in production, the equipment can operate continuously, reducing downtime and improving overall production efficiency. Attached Figure Description

[0026] Please combine Figure 1-5 This embodiment provides a piston surface defect detection device, which includes a transmission detection mechanism 1, a separation mechanism 2, and a rejection mechanism 3. The separation mechanism 2 is located inside the transmission detection mechanism 1, and the rejection mechanism 3 is located inside the transmission detection mechanism 1.

[0027] The transmission detection mechanism 1 includes a bracket 101, a transmission device 102 is installed inside the bracket 101, a top plate 103 is fixedly connected to the top of the bracket 101, a vision detection device 104 is fixedly connected inside the transmission device 102, a support frame 105 is fixedly connected to the outer wall of the bracket 101, a rotating rod 106 is rotatably connected inside the support frame 105, an adjusting plate 107 is fixedly connected to the bottom of the rotating rod 106, a limiting post 108 is fixedly connected to the outer wall of the end of the rotating rod 106 away from the adjusting plate 107, a worm gear 109 is fixedly connected to the outer wall of the end of the rotating rod 106 near the limiting post 108, a worm 110 is meshed with the worm gear 109, a handle 111 is fixedly connected to the outer end of the worm 110, a connecting block 112 is rotatably connected to the outer wall of the worm 110, and the connecting block 112 is fixedly connected to the outer wall of the support frame 105.

[0028] The separating mechanism 2 includes a fixed plate 201, which is fixedly connected to the outer wall of the bracket 101, and a sliding rod 202 is slidably connected inside the fixed plate 201.

[0029] A baffle 203 is fixedly connected to the outer wall of the sliding rod 202, and a cylinder 204 is fixedly connected to the end of the sliding rod 202 away from the baffle 203. A support frame 205 is fixedly connected to the outer wall of the cylinder 204.

[0030] The support frame 205 is fixedly connected to the bottom of the fixed plate 201. The end of the baffle 203 away from the sliding rod 202 is slidably connected to the guide rod 206, which is fixedly connected to the bottom of the top plate 103.

[0031] The rejection mechanism 3 includes a fixing plate 301, which is fixedly connected to the outer wall of the bracket 101, and a support plate 302 is fixedly connected to the outer wall of the fixing plate 301.

[0032] A cylinder 303 is fixedly connected to the bottom of the support plate 302, a push block 304 is fixedly connected to the output end of the cylinder 303, and a fixing block 305 is fixedly connected to the top of the push block 304.

[0033] A support rod 306 is slidably connected inside the fixing block 305, and the support rod 306 is fixedly connected to the outer wall of the fixing plate 301.

[0034] The implementation principle of the piston surface defect detection device in this embodiment is as follows: After the piston is placed on the surface of the transmission device 102, it is restricted by the adjusting plate 107, causing the piston to move uniformly towards the center of the transmission device 102, so that the pistons are arranged in a straight line. A top plate 103 is fixed on the top of the support 101, and a visual inspection device 104 is fixed inside the top plate 103. When the piston reaches the bottom of the visual inspection device 104, it is inspected by the visual inspection device 104 to determine the integrity of the piston. By uniformly arranging the pistons, the performance of the visual inspection device 104 is improved. The detection efficiency of 4 avoids missed scans, reduces the possibility of missed judgments, and improves the reliability of piston quality. Simultaneously, personnel rotate the worm gear 110 via handle 111. When the worm gear 110 meshes with the worm wheel 109, it drives the rotating rod 106 to rotate. The rotating rod 106 is fixed to the adjusting plate 107, allowing the adjusting plate 107 to be adjusted at a certain angle around the rotating rod 106. This allows for the detection of pistons of different sizes, improving the overall flexibility of the equipment. The support frame 205 supports the cylinder 204, which is connected to the cylinder via the sliding rod 202. The baffle 203 moves by sliding against the outer wall of the guide rod 206, allowing it to rise and fall vertically. This controls the distance between each piston, ensuring uniform detection by the vision inspection device 104 and improving overall operational smoothness. When the vision inspection device 104 detects a defective piston, it sends an electrical signal to cylinder 303. Upon receiving the signal and starting operation, cylinder 303 pushes push block 304. Simultaneously, the output end of cylinder 303 slides through fixed plate 301, pushing block 304... Fixed to the fixed block 305, the sliding support rod 306 slides inside the fixed block 305. The support rod 306 ensures that the push block 304 moves in a straight line, thereby quickly removing defective products from the surface of the conveying device 102. The defective products fall into the collection box 307, which is convenient for personnel to collect. By reducing the frequency of manual intervention in production, the equipment can run continuously, reducing downtime and improving overall production efficiency. The above-mentioned vision inspection device 104 uses the In-Sight2000 model, which has a compact 2D vision sensor and is suitable for small-scale inspection.
