Description

Technical Field

[0001] This utility model relates to the field of production control technology, specifically to a side-push device for quality inspection. Background Technology

[0002] When factories produce corresponding products, they need to inspect the production quality of the products to determine whether they are qualified. For example, in the process of cardboard production, the company needs to press two boards of different shapes together, and then inspect the quality of the pressed boards to determine whether the pressed boards are properly pressed and adhered, and whether there is any damage during the pressing process.

[0003] In existing technologies, when batch quality inspection is carried out by conveyor belts, the process often involves temporarily stopping the machine and then manually removing the defective products, or numbering the defective products according to the system program and then manually finding and removing the corresponding defective products. However, the methods of temporarily stopping the machine or finding defective products by number are time-consuming and labor-intensive, which is not conducive to the mass production of factories. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention aims to provide a side-pushing device for quality inspection. This solution can push unqualified products to the other side of the conveyor belt, thereby preventing them from continuing to mix with qualified products. Unqualified products can be quickly found and removed without stopping the machine, thus improving screening efficiency.

[0005] This utility model is achieved through the following technical solution: A side-push device for quality inspection, comprising: A conveyor belt, with a quality inspection unit for detecting the production quality of the products installed above the conveyor belt; At or behind the detection position, a push cylinder is provided on one side of the conveyor belt frame, and a baffle is provided on the other side of the frame; the quality detection unit is used to control the extension and retraction of the push cylinder according to its own detection results; The extension and retraction direction of the push cylinder is towards the baffle; the baffle is used to block the product and prevent the product from falling off the conveyor belt.

[0006] Compared to existing technologies that rely on temporary shutdowns or sequentially searching for defective products by number, which are time-consuming and labor-intensive and detrimental to mass production in factories, this invention provides a side-pushing device for quality inspection. This solution pushes defective products to the other side of the conveyor belt, preventing them from mixing with qualified products. Defective products can be quickly located and removed without stopping the machine, thus improving screening efficiency. In the specific solution, a conveyor belt sequentially transports several products, such as pressed plates. In previous processes, the products should be placed on one side of the conveyor belt's centerline for transport. A quality inspection unit is installed along the conveyor belt's path. This unit is a conventional inspection device that can capture images via a camera and compare and analyze the images to determine whether the product is qualified. This is existing technology and will not be elaborated here. At or behind the inspection position, push cylinders and baffles are respectively installed on both sides of the conveyor belt. If the quality inspection unit determines that a product is unqualified, it outputs a control signal to the push cylinder. When the product is at the push cylinder (where a sensor is installed), the push cylinder extends and pushes the product to the other side of the conveyor belt's centerline, where it is blocked by the baffle. In this way, several qualified products are transported on one side of the conveyor belt's centerline, while several unqualified products are transported on the other side, separating the two. At this point, the operator only needs to quickly remove the unqualified products at a subsequent fixed location without needing to distinguish and select them again.

[0007] Further optimization includes a fixed frame for the fixed quality inspection unit, which spans across the conveyor belt and is fixedly connected to the frame on both sides of the conveyor belt; the quality inspection unit is fixed on the fixed frame.

[0008] To further optimize the system and reduce interference from external light on camera shooting, a light-shielding plate is provided on the top surface of the mounting bracket.

[0009] Further optimization involves a fixed baffle, wherein the fixed frame includes two vertical rods located on the other side of the conveyor belt, and the two ends of the baffle are respectively connected to the two vertical rods.

[0010] Further optimization includes a lifting drive component for automatic product screening. The baffle's two ends are slidably connected to two vertical rods. The lifting drive component moves the baffle up and down, creating a gap for products to pass through. In this solution, the quality inspection unit can further screen and determine the product pass rate. If the pass rate reaches 80%~90%, the product is repairable; if the pass rate is below 80%, it is seriously defective and needs to be discarded or remanufactured. The pass rate classification is based on existing technology. If the product is a pressed plate, the quality inspection unit can distinguish it into qualified products, products with low bonding integrity, or products with pressing damage. Products with low bonding integrity can be re-bonded, while products with pressing damage are unusable and need to be scrapped and remanufactured. Therefore, this solution also includes a lifting drive mechanism. Both ends of the baffle are slidably connected via sliders and two vertical rods. This way, when the quality inspection unit detects products with low adhesion integrity, the baffle does not need to move, allowing these products to continue conveying on the other side of the conveyor belt. However, when the quality inspection unit detects products with pressure-induced defects, it outputs a signal to control the lifting drive mechanism to raise the vertical rods and simultaneously drive the push cylinder to increase its stroke, completely pushing these products out of the gap below the baffle from the conveyor belt, thus achieving sorting. Additionally, it can also be done as follows... Figure 5 As shown, by increasing the spacing between the two rods, the clearance through which the product passes is increased to accommodate larger products and increased stroke.

[0011] Further optimization involves installing a lifting drive component, with a horizontal bar positioned between the two vertical bars. This horizontal bar is located above the baffle, and the lifting drive component is fixed to the horizontal bar, with its output end facing downwards and connected to the center of the upper side of the baffle. The lifting drive component can be a hydraulic cylinder or a lifting pneumatic cylinder.

[0012] To further optimize the process, in order to guide products with press-fitted defects into another conveying or storage device, a downwardly inclined chute is provided on the other side of the conveyor belt.

[0013] To further optimize the process, a limiting rod is installed on the conveyor belt in front of the fixed frame to separate the initial products for transport along one side of the conveyor belt centerline. This limiting rod is positioned along the conveying direction of the conveyor belt and located at its center. The limiting rod is suspended and fixed to a support on the other side of the conveyor belt via a connecting rod on one side. Baffles can be installed on both sides of the conveyor belt in front of and behind the side-pushing device. The limiting rod is suspended and fixed to the other side of the conveyor belt via a connecting rod, ensuring that products can only enter the side-pushing device from one side of the conveyor belt.

[0014] To further optimize the process and reduce damage to the product during pushing, a first flexible layer is bonded to the output end of the pushing cylinder.

[0015] To further optimize the process and reduce damage to the product during the blocking process, a second flexible layer is bonded to the surface of the baffle.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects: 1. This utility model provides a side-pushing device for quality inspection. By using this solution, unqualified products can be pushed to the other side of the conveyor belt, thereby preventing them from continuing to mix with qualified products. Unqualified products can be quickly found and removed, improving screening efficiency.

[0017] 2. This utility model provides a side-pushing device for quality inspection. When the quality inspection unit detects a product with low adhesion integrity, the baffle does not need to move, allowing such products to continue to be conveyed on the other side of the conveyor belt. However, when the quality inspection unit detects a product with a pressure break, the quality inspection unit outputs a signal to control the lifting drive component to raise the vertical rod and simultaneously drive the push cylinder to increase the stroke, so as to completely push such products out of the gap below the baffle from the conveyor belt, thereby achieving further classification.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0021] Example: This embodiment provides a side-push device for quality inspection, such as... Figures 1-5 As shown, it includes: Conveyor belt 1, with a quality inspection unit 9 for detecting the production quality of products installed above the conveyor belt 1; At or behind the detection position, a push cylinder 3 is provided on one side of the frame of the conveyor belt 1, and a baffle 4 is provided on the other side of the frame; the quality detection unit 9 is used to control the extension and retraction of the push cylinder 3 according to its own detection results; The extension and retraction direction of the push cylinder 3 is towards the baffle 4; the baffle 4 is used to block the product and prevent the product from falling off the conveyor belt 1.

[0022] Compared to existing technologies that rely on temporary shutdowns or sequentially searching for defective products by number, which are time-consuming and labor-intensive and detrimental to mass production in factories, this invention provides a side-pushing device for quality inspection. This solution pushes defective products to the other side of the conveyor belt 1, thereby preventing them from being mixed with qualified products. Defective products can be quickly found and removed without stopping the machine, improving screening efficiency. In the specific scheme, conveyor belt 1 sequentially transports several products, such as pressed plates. In previous processes, the products should be placed on one side of the center line of conveyor belt 1 for transport. A quality inspection unit 9 is set on the transport path of conveyor belt 1. The quality inspection unit 9 is a conventional inspection device that can capture images through a camera and compare and analyze the images to determine whether the product is qualified. This is existing technology and will not be described in detail here. At or behind the inspection position, push cylinders 3 and baffles 4 are respectively set on both sides of conveyor belt 1. If the quality inspection unit 9 determines that the product is unqualified, it outputs a control signal to push cylinder 3. When the product is at push cylinder 3 (at which time a sensor is installed), push cylinder 3 extends and pushes the product to the other side of the center line of conveyor belt 1, where it is blocked by baffle 4. In this way, several qualified products are transported on one side of the center line of conveyor belt 1, while several unqualified products are transported on the other side of the center line of conveyor belt 1, thus separating the two. At this time, the operator only needs to quickly remove the unqualified products at the subsequent fixed position without further differentiation and selection.

[0023] In some embodiments, the fixed quality detection unit 9 also includes a fixing frame 2, which spans across the conveyor belt 1 and is fixedly connected to the frame on both sides of the conveyor belt 1; the quality detection unit 9 is fixed on the fixing frame 2.

[0024] In some embodiments, a light-shielding plate 201 is provided on the top surface of the mounting bracket 2 to provide light protection and reduce interference from external light on camera shooting.

[0025] In some embodiments, the baffle 4 is a fixed baffle 2, which includes two vertical rods located on the other side of the conveyor belt 1, and the two ends of the baffle 4 are respectively connected to the two vertical rods.

[0026] In some embodiments, for further automatic product screening, a lifting drive 5 is also included. The two ends of the baffle 4 are slidably connected to two vertical rods respectively. The lifting drive 5 is used to drive the baffle 4 to rise and fall. The rising of the baffle 4 is used to leave a gap for products to pass through below. In this solution, the quality inspection unit 9 can further screen and determine the product qualification rate. If the qualification rate reaches 80%~90%, it is a repairable product; if the qualification rate is below 80%, it is seriously unqualified and needs to be discarded or remanufactured. Its qualification rate classification is based on existing technology. If the product is a pressed plate, it can be distinguished by the quality inspection unit 9 into qualified products, products with low bonding integrity, or products with pressing damage. Products with low bonding integrity can be re-bonded, while products with pressing damage are unusable and need to be scrapped and remanufactured. Therefore, this solution also includes a lifting drive component 5. Both ends of the baffle 4 are slidably connected via sliders and two vertical rods. This way, when the quality inspection unit 9 detects a product with low adhesion integrity, the baffle 4 does not need to move, allowing such products to continue being conveyed on the other side of the conveyor belt 1. However, when the quality inspection unit 9 detects a product with a pressure break, it outputs a signal to control the lifting drive component 5 to raise the vertical rods and simultaneously drive the push cylinder 3 to increase its stroke, completely pushing such products out of the gap below the baffle 4 from the conveyor belt 1, thus achieving sorting. Additionally, it can also be done as follows... Figure 5 As shown, by increasing the spacing between the two rods, the clearance through which the product passes is increased to accommodate larger products and increased stroke.

[0027] In some embodiments, a horizontal bar is provided between the two vertical rods to accommodate the lifting drive component 5. The horizontal bar is located above the baffle 4, and the lifting drive component 5 is fixed to the horizontal bar. The output end of the lifting drive component 5 faces downward and is connected to the center of the upper side of the baffle 4. The lifting drive component 5 can be a hydraulic cylinder or a lifting pneumatic cylinder.

[0028] In some embodiments, in order to guide a product with a press-fitted break into another conveying or storage device, a downwardly inclined chute 6 is provided on the other side of the conveyor belt 1.

[0029] In some embodiments, to separate the initial products and transport them to one side of the centerline of the conveyor belt 1, a limiting rod 7 is also provided on the conveyor belt 1 located in front of the fixing frame 2. The limiting rod 7 is arranged along the conveying direction of the conveyor belt 1 and is located at the center of the conveyor belt 1. The limiting rod 7 is suspended and fixed to the support on the other side of the conveyor belt 1 by a connecting rod 8 on one side. Baffles can be provided on both sides of the conveyor belt 1 in front of and behind the side-pushing device. The limiting rod 7 is suspended and fixed to the other side of the conveyor belt 1 by the connecting rod 8, so that the product can only enter the side-pushing device from one side of the conveyor belt 1.

[0030] In some embodiments, to reduce damage to the product during pushing, a first flexible layer 301 is adhered to the output end of the pushing cylinder 3.

[0031] In some embodiments, to reduce damage to the product during the process of blocking the product, a second flexible layer 401 is adhered to the surface of the baffle 4.
