[0024] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0026] This application discloses a transport device for material trays.

[0027] Reference Figure 1A conveying device for a material tray includes a frame 1, a slide rail 11 mounted on the frame 1, a tray 2 slidably mounted on the slide rail 11, a drive assembly 3 and a positioning assembly 4 mounted on the frame 1. The drive assembly 3 drives the tray 2 to slide on the frame 1, and the positioning assembly 4 controls the travel distance of the tray 2 on the frame 1. A centering assembly 5 is mounted on the tray 2 for positioning the material tray.

[0028] Reference Figure 2 The drive assembly 3 includes a first rotating shaft 31 and a second rotating shaft 32. The first rotating shaft 31 is rotatably mounted on a frame 1. An adjustment groove 12 is provided on the frame 1. The adjustment groove 12 has a rectangular cross-section, and its length is parallel to the line connecting the bearing axes of the first rotating shaft 31 and the second rotating shaft 32. An adjustment rod 33 is mounted on the second rotating shaft 32. One end of the adjustment rod 33 is coaxially connected to the second rotating shaft 32, and the other end passes through the adjustment groove 12. A fixing plate 331 is provided at the end of the adjustment rod 33 passing through the adjustment groove 12. The fixing plate 331 is circular, and its axis is coaxial with the axis of the adjustment rod 33. A fixing bolt 332 is provided on the fixing plate 331. One end of the fixing bolt 332 passes through the fixing plate 331, and the end of the fixing bolt 332 passing through the fixing plate 331 is threadedly connected to the adjustment rod 33. In use, rotate the fixing bolt 332 so that one side of the fixing plate 331 is pressed against the frame 1.

[0029] A conveyor belt 34 is disposed between the first rotating shaft 31 and the second rotating shaft 32, with both ends of the conveyor belt 34 fitted onto the first rotating shaft 31 and the second rotating shaft 32. The conveyor belt 34 has internal teeth 341 formed on the side closest to the first rotating shaft 31 and the second rotating shaft 32, and external teeth 311 formed on the first rotating shaft 31 and the second rotating shaft 32. The conveyor belt 34 meshes with the first rotating shaft 31 and the second rotating shaft 32. When adjusting the conveyor belt 34, the second rotating shaft 32 is adjusted along the adjusting groove 12 to adjust the distance between the first rotating shaft 31 and the second rotating shaft 32, so that the conveyor belt 34 can be tensioned between the first rotating shaft 31 and the second rotating shaft 32.

[0030] Furthermore, a drive motor 13 is provided on the frame 1. The drive motor 13 is mounted on the frame 1, and the output shaft of the drive motor 13 is connected to the first rotating shaft 31. In use, the drive motor 13 drives the first rotating shaft 31 to rotate, and at the same time, the conveyor belt 34 rotates on the first rotating shaft 31 and the second rotating shaft 32.

[0031] Reference Figure 3 A connecting part 21 is provided on the pallet 2, and the pallet 2 is connected to only one side of the conveyor belt 34. When the conveyor belt 34 rotates forward or backward, it drives the connecting part 21 to move synchronously, thereby causing the pallet 2 to move along the moving direction of the conveyor belt 34.

[0032] The connecting part 21 includes a support plate 22, which is arranged parallel to and spaced apart from the conveyor belt 34. One end of the support plate 22 is connected to the pallet 2, and the other end extends towards the side closer to the conveyor belt 34. A pressure plate 23 is provided on the side of the conveyor belt 34 opposite to the support plate 22 in the thickness direction. A connecting bolt 24 is provided on the pressure plate 23. One end of the connecting bolt 24 passes through the pressure plate 23 and connects to the support plate 22. The pressure plate 23 and the support plate 22 clamp the conveyor belt 34, thereby improving the stability of the conveyor belt 34 driving the pallet 2 to move.

[0033] In actual use, the movement of pallet 2 is adjusted by the rotation interval of conveyor belt 34 to improve the convenience of pallet 2 movement adjustment. Positioning component 4 includes photoelectric switches 41, with two photoelectric switches 41 spaced apart on the frame 1. In the prior art, a photoelectric switch 41 is a device that uses the principle of light to detect the presence or position of an object and control the circuit switch. It typically consists of a light source and a receiver. When the light beam is blocked or reflected by an object, the signal of the receiver changes, thereby triggering the circuit switch.

[0034] A baffle 25 is provided on the tray 2. During use, the tray 2 slides between two photoelectric switches 41 via the baffle 25. When it is necessary to adjust the sliding stroke of the tray 2, it is only necessary to adjust the distance between the two photoelectric switches 41 to adjust the movement stroke of the tray 2.

[0035] Reference Figure 4 To improve the accuracy of the tray's position on pallet 2 when conveying different trays, a centering mechanism includes positioning plates 51. The tray is rectangular in shape, and two positioning plates 51 are spaced apart on each side of the tray in both the length and width directions. One end of the positioning plate 51 is connected to pallet 2, and the other end extends away from the conveyor belt 34 in the thickness direction of pallet 2. A guide slope 52 is formed on the side of the positioning plate 51 away from the conveyor belt 34, facing the side closer to pallet 2. In use, the guide slope 52 on the positioning plate 51 guides the tray.

[0036] Adjusting bolts 53 are provided on the positioning plate 51. Two adjusting bolts 53 are spaced apart on the positioning plate 51. One end of the adjusting bolt 53 passes through the positioning plate 51 and is threadedly connected to the tray 2. The positioning plate 51 is slidably mounted on the adjusting bolt 53. A support spring 54 is provided on the side of the positioning plate 51 away from the tray 2 in the thickness direction. The support spring 54 is sleeved on the adjusting bolt 53 and abuts against the side of the positioning plate 51 away from the tray 2 in the thickness direction. The other end abuts against the adjusting bolt 53. The elastic force of the support springs 54 on the periphery of the tray 2 is the same. Since the support springs 54 are evenly distributed on the tray 2 and the elastic force of the support springs 54 is the same, the force exerted by each support spring 54 on the plate is uniform, and the force on each point on the tray is relatively symmetrical. The tray will be located at the center of the tray 2 under the balance of gravity and the reaction force of the springs.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
