Description

Technical Field

[0001] This utility model relates to the field of metal parts conveying technology, and in particular to a limiting mechanism for a metal parts surface treatment conveyor. Background Technology

[0002] Surface treatment is a process that artificially forms a layer on the surface of a base material that has different mechanical, physical, and chemical properties from the base material. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decorative, or other special functional requirements of a product. For metal castings, commonly used surface treatment methods include mechanical grinding, chemical treatment, surface heat treatment, and surface coating. Surface treatment involves cleaning, sweeping, deburring, removing oil stains, and removing oxide scale from the workpiece surface.

[0003] Traditionally, metal parts are fed by placing them on the conveyor belt of a conveyor seat. However, this process can lead to issues such as metal parts being placed at the edge of the conveyor belt, causing friction between them and the conveyor seat, or the metal parts being placed in a messy manner, making it difficult for the robotic arm to grip them later. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a limiting mechanism for a metal surface treatment conveyor, so as to solve the problems that the metal parts are located at the edge of the conveyor belt, causing friction between them and the conveyor seat, or that the metal parts are placed in a messy manner, which is not conducive to the gripping of the robotic arm later.

[0005] To achieve the above objectives, this utility model provides a limiting mechanism for a metal parts surface treatment conveyor, including a conveyor base, on which two conveyor rollers are symmetrically mounted, and a conveyor belt for conveying metal parts is connected between the two conveyor rollers. A motor connected to the end of one of the conveyor rollers is mounted on the conveyor base. The mechanism also includes: Two L-shaped, symmetrically distributed push plates slide on both sides of the conveyor seat to push the metal parts at the edge of the conveyor belt closer to the center of the conveyor belt; Two symmetrically distributed and inclined limiting plates are set at the top of the conveyor seat and on the top surface of the conveyor belt to limit the metal parts near the middle of the conveyor belt.

[0006] Preferably, a rotating shaft that is rotatably connected to the conveyor seat is fixedly installed on the limiting plate, and a worm gear is fixedly connected to the top of each of the two rotating shafts.

[0007] Preferably, the conveyor seat is provided with an adjustment unit for adjusting the angle of the two limiting plates. The adjustment unit includes support plates symmetrically installed on the side wall of the conveyor seat, and a rotating shaft is rotatably installed between the two support plates. A motor is installed on one side of one of the support plates and connected to one end of the rotating shaft. Worms that mesh with worm gears are symmetrically installed on the rotating shaft.

[0008] Preferably, both sides of the conveyor seat are provided with a pushing unit for moving the push plate. The pushing unit includes a half gear installed at the end of the conveyor roller. A movable plate located below the push plate and in contact with the side wall of the push plate is slidably provided at the top of the conveyor seat. The movable plate has an inclined edge on the side near the push plate. A toothed plate meshing with the half gear and a sliding cylinder located on one side of the toothed plate are installed at the bottom of the movable plate. A movable groove for sliding the sliding cylinder is provided at the top of the conveyor seat. An elastic element connected to the sliding cylinder is installed in the movable groove.

[0009] Preferably, the elastic element includes a stabilizing rod installed inside the moving groove, one end of the stabilizing rod being inserted into the interior of the sliding sleeve, and a spring being sleeved on the stabilizing rod and fixedly connected to the side wall of the moving groove and one end of the sliding sleeve.

[0010] Preferably, the conveyor seat is equipped with a fixing plate located on one side of the support plate on both sides.

[0011] Preferably, a stabilizing component for stabilizing the movement of the two push plates is installed between the two fixed plates and between the two support plates. The stabilizing component includes a slide rod fixedly installed between the two fixed plates and between the two support plates. A slide plate fixedly connected to the top of the push plate is slidably installed on each slide rod. Springs are sleeved at both ends of one of the slide rods and fixedly connected to the side wall of the fixed plate and the slide plate.

[0012] Preferably, rollers are installed at equal distances on one side of both limiting plates.

[0013] The beneficial effects of this utility model are as follows: By setting up a conveyor seat, conveyor roller, conveyor belt and motor, it is convenient for the conveyor belt to carry metal parts for conveying. Through the design of two push plates, the metal parts located at the edge of the conveyor belt can be moved in a direction perpendicular to the transmission direction of the conveyor belt, pushing the metal parts closer to the middle of the conveyor belt. As the conveyor belt carries the metal parts closer to the limiting plate, the inclined limiting plate can limit the metal parts that are placed randomly on the conveyor belt, making it convenient to move the metal parts to the middle part of the conveyor belt, preventing the metal parts from being in different positions, effectively realizing the neat conveying of metal parts by the conveyor belt, and thus providing convenience for the robotic arm to grip the metal parts later.

[0019] This specification provides one or more embodiments of a limiting mechanism for a metal surface treatment conveyor, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a conveyor base 1, on which two conveyor rollers 2 are symmetrically mounted, and a conveyor belt 3 for conveying metal parts is connected between the two conveyor rollers 2. A motor 4 connected to the end of one of the conveyor rollers 2 is mounted on the conveyor base 1. The device also includes: Two L-shaped push plates 13, symmetrically distributed, slide on both sides of the conveyor seat 1 to push the edge metal parts of the conveyor belt 3 closer to the middle of the conveyor belt 3. Two symmetrically distributed and inclined limiting plates 6 are set at the top of the conveyor seat 1 and on the top surface of the conveyor belt 3 to limit the metal parts near the middle of the conveyor belt 3.

[0020] In use, starting motor 4 will cause the conveyor roller 2 to rotate, which in turn will cause the conveyor belt 3 to work. When the metal part is placed on the conveyor belt 3, the conveyor belt 3 will move the metal part. When the metal part is located at the edge of the conveyor belt 3, the push plate 13 will move in a direction perpendicular to the transmission direction of the conveyor belt 3 due to the action of the push plate 13. This push plate 13 will push the metal part closer to the middle of the conveyor belt 3, preventing the metal part from being located at the edge of the conveyor belt 3. As the conveyor belt 3 moves the metal part closer to the limiting plate 6, the limiting plate 6 can limit the randomly placed metal parts, making it easier to move the metal parts to the middle of the conveyor belt and prevent the metal parts from being in different positions. This effectively realizes the neat conveying of metal parts by the conveyor belt 3, thus providing convenience for the robotic arm to grip the metal parts later.

[0021] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, a rotating shaft 5, which is rotatably connected to the conveyor seat 1, is fixedly installed on the limiting plate 6, and a worm gear 7 is fixedly connected to the top of each of the two rotating shafts 5. This design, through the rotatable connection between the rotating shafts 5 and the conveyor seat 1, effectively provides the possibility of adjusting the angle of the limiting plate 6, enabling the inclined limiting plate 6 to limit the randomly placed metal parts, thereby providing the possibility of orderly placement of the metal parts.

[0022] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the conveyor seat 1 is provided with an adjustment unit for adjusting the angle of the two limiting plates 6. The adjustment unit includes support plates 8 symmetrically installed on the side wall of the conveyor seat 1. A rotating shaft 10 is rotatably installed between the two support plates 8. A motor 9 connected to one end of the rotating shaft 10 is installed on one side of one of the support plates 8. Worms 11 that mesh with worm gears 7 are symmetrically installed on the rotating shaft 10. It should be noted that the threads of the two worms 11 are opposite. This design allows the rotating shaft 10 to rotate when the motor 29 is started. The rotating shaft 10 then drives the two worm gears 11 to rotate synchronously. Through the meshing connection between the worm gears 11 and the worm wheel 7, the worm wheel 7 rotates, causing the rotating shaft 5 to rotate. In turn, the rotating shaft 5 drives the limiting plate 6 to rotate. By adjusting the tilt of the limiting plate 6, it is possible to limit the metal parts conveyed by the conveyor belt 3. During the process of the conveyor belt 3 carrying the metal parts, the limiting effect of the limiting plate 6 can push the metal parts to the middle part of the conveyor belt 3, preventing the metal parts from being out of place and effectively facilitating the subsequent gripping of the metal parts by the robotic arm.

[0023] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, both sides of the conveyor seat 1 are provided with a pushing unit to move the push plate 13. The pushing unit includes a half gear 18 installed at the end of the conveyor roller 2. A movable plate 16 is slidably located below the push plate 13 and in contact with the side wall of the push plate 13 at the top of the conveyor seat 1. The movable plate 16 has an inclined edge 22 on the side near the push plate 13. A toothed plate 17 that meshes with the half gear 18 and a sliding cylinder 19 located on one side of the toothed plate 17 are installed at the bottom of the movable plate 16. A movable groove 24 for the sliding cylinder 19 to slide is opened at the top of the conveyor seat 1. An elastic element connected to the sliding cylinder 19 is installed in the movable groove 24. With this design, when the conveyor roller 2 performs the conveying work of the conveyor belt 3, the conveyor roller 2 will drive the half gear 18 to rotate. Through the meshing connection between the half gear 18 and the toothed plate 17, the toothed plate 17 will drive the moving plate 16 to slide at the top of the conveyor seat 1. The moving plate 16 will drive the sliding seat cylinder 19 to slide inside the moving groove 24, and will cause the elastic element to move. Due to the action of the inclined side 22, the sliding contact between the moving plate 16 and the inner wall of the push plate 13 during the movement will push the push plate 13 to slide towards the middle position of the conveyor belt 3, so that the two push plates 13 can move closer to each other, making it easier to move the metal part on one side of the push plate 13 closer to the middle of the conveyor belt 3. When the half gear 18 continues to rotate, it will disengage from the toothed plate 17. Then, under the action of the elastic element, the moving plate 16 will slide in the opposite direction and the two push plates 13 will move away from each other, effectively realizing the reciprocating motion of the push plate 13.

[0024] In embodiments of this utility model, such as Figure 2 and Figure 3 As shown, the elastic element includes a stabilizing rod 20 installed inside the moving groove 24. One end of the stabilizing rod 20 is inserted into the interior of the sliding cylinder 19. A spring 21 is sleeved on the stabilizing rod 20 and fixedly connected to the side wall of the moving groove 24 and one end of the sliding cylinder 19. With this design, the movement of the moving plate 16 will cause the sliding cylinder 19 to slide inside the moving groove 24, causing the sliding cylinder 19 to slide on the stabilizing rod 20 and compressing the spring 21, thus bringing the two push plates 13 closer together. When the half gear 18 disengages from the toothed plate 17, the spring 21 will cause the moving plate 16 to move in the opposite direction, thereby causing the inclined side 22 to move in the opposite direction and the push plate 13 to move in the opposite direction, effectively realizing the reciprocating motion of the push plate 13.

[0025] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the conveyor seat 1 has a fixing plate 12 installed on both sides of the support plate 8. This design, through the design of the fixing plate 12, effectively provides the possibility for stable movement of the push plate 13.

[0026] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, stabilizing components for stabilizing the movement of the two push plates 13 are installed between the two fixed plates 12 and between the two support plates 8. These stabilizing components include slide rods 14 fixedly installed between the two fixed plates 12 and between the two support plates 8. Each slide rod 14 has a sliding plate 15 slidably mounted on it and fixedly connected to the top of the push plate 13. Both ends of one slide rod 14 are fitted with springs 25 fixedly connected to the side walls of the fixed plates 12 and the sliding plate 15. This design ensures that when the push plate 13 moves, the sliding plate 15 slides on the slide rod 14, effectively improving the smoothness of the push plate 13's movement. When the two sliding plates 15 approach each other, the springs 25 are stretched and generate elastic force. When the moving plate 16 moves in the opposite direction, the force of the springs 25 causes the two sliding plates 15 to move away from each other, providing the possibility for the two sliding plates 15 to reset and for the two push plates 13 to move in the opposite direction.

[0027] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, rollers 23 are installed at equal distances on one side of both limiting plates 6. With this design, when the conveyor belt 3 drives the metal parts to be conveyed, the limiting effect of the limiting plates 6 will cause the metal parts to slide on the rollers 23 on the side wall of the limiting plates 6, thereby reducing friction.
