Description

Technical Field

[0001] This invention relates to the field of vacuum cleaner parts processing technology, specifically to a parts conveyor for assembly lines. Background Technology

[0002] Vacuum cleaners mainly consist of three parts: dust collection, dust suction, and dust filtration. They have a wide variety of accessories, including power components, dust filtration components, housing components, bends, sealing rings, screws, and other small parts, which vary in shape and material. In the mass production of vacuum cleaners, various components need to be transported to the assembly station in an orderly manner by conveying equipment, and the assembly equipment completes the assembly of the whole machine. For example, a mobile inclined conveyor with announcement number CN209618215U solves the problems of existing inclined conveyors, which occupy a large area, are inconvenient to move, and are prone to slippage when the tilt angle is too large. It includes pulleys, with a base fixed to the top of the pulleys, a fixing block fixed between the inner sides of the base, a storage battery fixed inside the fixing block, support plates fixed on both sides of the upper part of the base, a protective plate connected between the inner sides of the support plates through a first rotating shaft, rollers fixed between the inner sides of the protective plate and the inner sides of the support plate, a motor fixed on one side of the rear end of the protective plate and one side of the rear end of the support plate, and a spring assembly fixed on the outer side of one end of the support plate. The structure is novel, ingenious, and easy to operate. The support assembly not only makes it easy to adjust the tilt angle of the inclined conveyor, but also makes it easy to lower the height of the inclined conveyor and move the inclined conveyor. The spring assembly can make the belt of the inclined conveyor work stably when adjusting the angle. For example, CN213036753U describes a conveyor mechanism for a suspended production line of bridge metal fittings, including a worktable. This conveyor mechanism, through a driven shaft and driven roller mounted on a support top plate, allows the driven shaft, which can rotate inside the support top plate, to rotate. The driven roller, through its contact with the conveyor belt, drives the driven roller as the conveyor belt rotates, which in turn drives the driven shaft. This rotation of the driven shaft ensures stable movement of the conveyor belt. Furthermore, the contact between the driven roller and the conveyor belt provides support, preventing the conveyor belt from losing tension due to the metal fittings pulling on the suspension rings and applying tension. The driven roller design ensures both stable conveyor belt movement and prevents belt tension from being stretched. However, the above-mentioned conveyor still has the following drawbacks in actual use: 1. Some conveyors are equipped with structures to remove defective products, but these structures can easily cause secondary damage to the defective products during the feeding process, affecting the repair and reuse of the products. Therefore, there is a lack of buffer protection structures during feeding. 2. Furthermore, some vacuum cleaner accessories need to be transported in different directions, and traditionally multiple conveyors are used in combination, which increases costs, or the conveyors are moved to change direction, lacking components that can flexibly adjust the transport direction.

[0003] To address the aforementioned issues, innovative designs are urgently needed based on the existing parts conveyor system. Summary of the Invention

[0004] The purpose of this invention is to provide a component conveyor for assembly lines, which solves the problems mentioned in the background art, such as the tendency of traditional conveyors to cause secondary damage to defective products during the material pushing process, affecting the repair and reuse of products, and the lack of components that can flexibly adjust the conveying direction.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a component conveyor for an assembly line, comprising a first conveyor belt and a second conveyor belt, wherein the second conveyor belt is installed below the end of the first conveyor belt, and a defective product detector is provided on the first conveyor belt; It also includes: a pushing mechanism, which is set on one side of the first conveyor belt and is used to reject defective products; a receiving mechanism is set on the other side of the first conveyor belt and is used to store defective products; and a second conveyor belt is movably set below the first conveyor belt and the second conveyor belt conveys products in different directions through a turning mechanism.

[0006] Preferably, the pushing mechanism includes a telescopic cylinder installed on the side of the first conveyor belt, and the output shaft of the telescopic cylinder is connected to a push plate. One side of the push plate is connected to an external air supply device through an air supply pipe. When the telescopic cylinder is running, it can push unqualified products by pushing materials.

[0007] Preferably, a protective pad is attached to the other side of the push plate, and the protective pad has a hollow structure. The inside of the protective pad is connected to the air supply pipe, and air outlet holes are evenly reserved on the side of the protective pad away from the push plate. When pushing unqualified products, the protective pad can prevent product damage.

[0008] Preferably, the receiving mechanism includes a receiving box disposed on the other side of the first conveyor belt, and a receiving plate is disposed above the receiving box, and an elastic net is disposed on the inner side of the receiving plate. The receiving plate and the elastic net have a buffering effect on the falling defective products.

[0009] Preferably, the receiving plate is rotatably installed on the inner side of the protective plate, and the receiving plate has an inclined structure. The protective plate is fixed to the side of the first conveyor belt, and the rotation range of the receiving plate is 0-90°. The receiving plate can more accurately catch defective products by rotating.

[0010] Preferably, a connecting rod is fixed on the output shaft of the telescopic cylinder, and a rack is connected to the end of the connecting rod away from the output shaft of the telescopic cylinder. The rack and the gear are meshed, and the connecting shaft is fixedly inserted through the inside of the gear. At the same time, the connecting shaft is connected to the rotating shaft of the receiving plate through a pulley mechanism. The receiving plate is driven to rotate by the meshing of the gear and the rack, as well as the transmission of the pulley mechanism.

[0011] Preferably, the steering mechanism includes a motor installed below the second conveyor belt, and the motor is mounted on a support frame below the first conveyor belt. A movable ring is fixed to the outer side of the second conveyor belt. When the motor is driven, it causes the movable ring to slide on the support rod for steering the second conveyor belt.

[0012] Preferably, the movable ring and the support rod are circumferentially rotatably connected, and the support rod is fixed on the first conveyor belt. The rotation range of the second conveyor belt is 0-270°, and the surface of the second conveyor belt is uniformly reserved with fixing holes. The fixing holes facilitate the entry of negative pressure gas to adsorb the product.

[0013] Preferably, a fixing box is attached to the inner side of the second conveyor belt, and the fixing box is fixed to the plate structure on both sides of the second conveyor belt. The bottom of the fixing box is connected to an external negative pressure device through a negative pressure pipe. When the negative pressure adsorbs the product, it can prevent the product position from shifting when turning.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This component conveyor for assembly lines has a buffer protection structure when rejecting defective products on the conveyor, which can prevent secondary damage to defective products caused by excessive thrust, facilitating product repair and reuse. Furthermore, it allows for flexible adjustment of the component conveying direction, eliminating the need for multiple conveyors and reducing production costs. Specific details are as follows: 1. The receiving plate is driven to rotate by the meshing transmission of rack and pinion and the transmission of pulley mechanism. Therefore, during the pushing process, the push plate can drive the downward tilting receiving plate to rotate to the upward tilting. This can just catch the unqualified products pushed out by the push plate. The product has a good buffering effect when it comes into contact with the elastic net, and will not be damaged by impact. When the push plate returns to its original position, it also drives the receiving plate to return to the downward tilting state so that the product falls into the receiving box. 2. External gas is transmitted to the protective pad through the gas supply pipe and discharged from the gas outlet. When the pusher plate is not pushing the material, the discharged gas blows towards the accessories to clean the dust. When the pusher plate is pushing the material, the discharged gas blows towards the accessories to assist in pushing. The protective pad is designed to prevent product damage during pushing. 3. When the electric motor drives the second conveyor belt to rotate, it can adjust the conveying direction of the product. At the same time, the external negative pressure is transmitted to the negative pressure pipe, which can transmit the gas on the surface of the product and the second conveyor belt through the fixing hole to the fixing box, so that the product can be adsorbed on the surface of the second conveyor belt. This way, the product position will not be offset due to inertia when turning. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-8 The present invention provides the following technical solution: Example 1: To address the problems existing in the prior art, this example provides the following technical solution: a component conveyor for an assembly line, comprising a first conveyor belt 1 and a second conveyor belt 17. The second conveyor belt 17 is installed below the end of the first conveyor belt 1, and a defective product detector is installed on the first conveyor belt 1. It also includes a pushing mechanism, located on one side of the first conveyor belt 1, used to remove defective products. A receiving mechanism is located on the other side of the first conveyor belt 1, used to store defective products. The second conveyor belt 17 is movably located below the first conveyor belt 1, and the second conveyor belt 17 conveys products in different directions via a turning mechanism.

[0019] Some conveyors are equipped with structures to reject defective products, but these structures can easily cause secondary damage to the defective products during the feeding process, affecting their repair and reuse. Therefore, they lack cushioning and protection structures during feeding. Figures 1-2 and Figures 5-8As shown, the pushing mechanism includes a telescopic cylinder 2 installed on the side of the first conveyor belt 1, and the output shaft of the telescopic cylinder 2 is connected to a push plate 3. One side of the push plate 3 is connected to an external air supply device through an air supply pipe 4. A protective pad 5 is pasted on the other side of the push plate 3. The protective pad 5 has a hollow structure. The interior of the protective pad 5 is connected to the air supply pipe 4. Air outlet holes 6 are evenly reserved on the side of the protective pad 5 away from the push plate 3. The receiving mechanism includes a receiving box 10 set on the other side of the first conveyor belt 1. A receiving plate 7 is set above the receiving box 10. An elastic net 8 is set on the inner side of the receiving plate 7. The receiving plate 7 is rotatably mounted inside the protective plate 9, and the receiving plate 7 has an inclined structure. The protective plate 9 is fixed to the side of the first conveyor belt 1, and the rotation range of the receiving plate 7 is 0-90°. A connecting rod 11 is fixed on the output shaft of the telescopic cylinder 2, and a rack 12 is connected to the end of the connecting rod 11 away from the output shaft of the telescopic cylinder 2. The rack 12 and the gear 13 are meshed, and a connecting shaft 14 is fixedly inserted through the inside of the gear 13. The connecting shaft 14 is connected to the rotating shaft of the receiving plate 7 through a pulley mechanism. The parts to be conveyed are placed on the first conveyor belt 1. When a defective product is detected during the conveying process, the telescopic cylinder 2 moves the push plate 3 to push the defective product out. Simultaneously, the telescopic cylinder 2 drives the connecting rod 11 to move synchronously, and also drives the rack 12 to move. Through the meshing transmission between the rack 12 and the gear 13, the connecting shaft 14 rotates, and then through the pulley mechanism, the receiving plate 7 rotates. Therefore, during the pushing process, the downward-tilting receiving plate 7 rotates to an upward-tilting position, thus precisely catching the defective product pushed out by the push plate 3. The product's contact with the elastic net 8 has a good cushioning effect, preventing impact damage. Plate 3 moves in the reverse direction to return to its original position. Through the meshing transmission of rack 12 and gear 13 and the transmission of pulley mechanism, it can drive receiving plate 7 to rotate back to its original position. At this time, the products on receiving plate 7 can fall into receiving box 10 for subsequent unified processing. During the transmission of accessories, external gas is transmitted to protective pad 5 through air pipe 4 and discharged from air outlet 6. When push plate 3 is not pushing material, the discharged gas blows towards accessories to clean dust. When push plate 3 pushes material, the discharged gas blows towards accessories to assist in pushing. The protective pad 5 is set to prevent product damage during pushing.

[0020] Example 2: Some vacuum cleaner accessories need to be conveyed in different directions. Traditionally, multiple conveyors are used in conjunction, increasing costs. Alternatively, the conveyors are moved to change direction, lacking flexible components for adjusting the conveying direction. Therefore, this example uses the following technical solution: Figures 1-4As shown, the steering mechanism includes a motor 18 mounted below the second conveyor belt 17, and the motor 18 is mounted on a support frame below the first conveyor belt 1. A movable ring 16 is fixed to the outer side of the second conveyor belt 17. The movable ring 16 and the support rod 15 are circumferentially rotatably connected. A ball bearing is provided between the top of the support rod 15 and the movable ring 16. The support rod 15 is fixed to the first conveyor belt 1. The rotation range of the second conveyor belt 17 is 0-270°. Fixing holes 19 are evenly provided on the surface of the second conveyor belt 17. A fixing box 20 is fitted to the inner side of the second conveyor belt 17. The fixing box 20 is fixed to the plate structure on both sides of the second conveyor belt 17. The bottom of the fixing box 20 is connected to the outer side through a negative pressure pipe 21. The system is connected to a negative pressure device. When the product is transferred to the second conveyor belt 17, and the conveying direction needs to be adjusted, the motor 18 drives the second conveyor belt 17 to rotate. The conveying direction can be changed every 90° of rotation. When the second conveyor belt 17 rotates, it drives the movable ring 16 to slide on the support rod 15, which can ensure the stability during rotation. When the second conveyor belt 17 turns, the negative pressure generated by the external negative pressure device is transmitted to the negative pressure pipe 21, which can transmit the gas between the product and the surface of the second conveyor belt 17 through the fixing hole 19 to the fixing box 20, so that the product can be adsorbed on the surface of the second conveyor belt 17. In this way, the product position will not be offset due to inertia when turning, ensuring stability so that subsequent products can be accurately conveyed.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
