[0002] In the field of high-precision manufacturing, the production environment has stringent requirements for cleanliness. Existing material conveying devices use belts to transport screen modules. The belts directly contact the trays carrying the screen modules. Due to factors such as friction and wear between the belt and the tray, and friction and wear between the belt and mechanical transmission components, particles are shed from the surface of the structural components, continuously generating dust. These dust pollutants disperse in the workshop and settle on the product surface, causing product defects. Summary of the Invention

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the problem that dust generated by belt scraping and wear in the prior art will pollute the production workshop and cause product defects. In this way, the dust-free pallet conveyor device absorbs the dust generated by the belt through vacuum suction holes and uses a vacuum filter to filter the air and dust, reducing the spread of dust in the workshop, improving the cleanliness of the workshop, and thus improving the product yield.

[0004] To solve the above-mentioned technical problems, this utility model provides a dust-free pallet conveying device, comprising,

[0005] frame;

[0006] A conveying mechanism is mounted on the frame, and the conveying mechanism is equipped with a synchronous belt and a synchronous pulley that meshes with the synchronous belt;

[0011] In one embodiment of this utility model, the dust collection box is provided with a drawer, and the cleaning component can be detachably installed in the drawer.

[0012] In one embodiment of this utility model, the opening of the vacuum suction hole is provided with an inlet chamfer.

[0013] In one embodiment of this utility model, the vacuum suction hole is located directly below the edge of the synchronous belt.

[0014] In one embodiment of this utility model, the vacuum suction plate is detachably connected to the frame, wherein the vacuum suction plate is provided with a strip-shaped connecting hole extending along the conveying direction, and a screw passes through the strip-shaped connecting hole to connect to the frame.

[0015] In one embodiment of the present invention, the conveying mechanism includes a first conveying mechanism and a second conveying mechanism disposed at the same height, wherein the first conveying mechanism is disposed on one side of the second conveying mechanism.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0029] Reference Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment of this utility model, a dust-free pallet conveying device is disclosed, comprising:

[0030] Rack 1;

[0031] A conveying mechanism is mounted on the frame 1, and the conveying mechanism is provided with a synchronous belt and a synchronous pulley that meshes with the synchronous belt;

[0032] A vacuum suction plate 3 is horizontally positioned below the synchronous belt and the synchronous pulley, and extends along the conveying direction of the synchronous belt to one side of the synchronous pulley. The vacuum suction plate 3 is provided with a vacuum suction hole 31, which is connected to the vacuum connector 2a6 of a vacuum filter (not shown).

[0033] The dust-free pallet conveying device described in this embodiment uses a vacuum suction plate 3 to draw dust generated by the synchronous belt into a vacuum filter through vacuum suction holes 31. The vacuum filter filters the air and dust, effectively reducing the dust generated by the scraping and wear of the synchronous belt in the workshop, improving the cleanliness of the workshop, and thus improving the product yield. The vacuum suction plate 3 is set below the synchronous belt and synchronous pulley, and the vacuum suction holes 31 actively capture dust, so that the dust is accurately adsorbed at the source, reducing the spread of dust. The vacuum suction plate 3 extends to one side of the synchronous pulley, forming a continuous negative pressure field in the downstream area of ​​the synchronous belt, increasing the adsorption area, and can adsorb the dust ejected and scattered along the tangential direction of the synchronous pulley when the synchronous belt and synchronous pulley mesh and separate.

[0034] Reference Figure 1 and Figure 2 As shown, in one embodiment of this utility model, the vacuum connector 2a6 is fixedly connected to the bottom of the vacuum suction plate 3. One end of the vacuum connector 2a6 is connected to the vacuum suction hole 31, and the other end is connected to the air inlet of the vacuum filter. The air outlet of the vacuum filter is connected to the air passage of the negative pressure device. Therefore, the negative pressure device can form a negative pressure on the surface of the vacuum suction plate 3. Dust and air are sucked into the vacuum suction hole 31 by the negative pressure. After passing through the vacuum connector 2a6, the dust and air enter the vacuum filter. The air is filtered by the vacuum filter and then discharged.

[0035] Reference Figure 2 As shown, in one embodiment of this utility model, the vacuum suction hole 31 is configured as a strip-shaped hole, which extends along the conveying direction. The strip-shaped hole can match the synchronous belt movement trajectory to improve the dust adsorption effect.

[0036] Reference Figure 3 As shown, in one embodiment of this utility model, the vacuum suction plate 3 has two strip holes on both sides. The two strip holes on each side are distributed along the conveying direction of the synchronous belt to form a continuous negative pressure field and continuously adsorb the falling dust.

[0037] Reference Figure 1 and Figure 6As shown, in one embodiment of this utility model, a plurality of cleaning components 5 are also included. The cleaning components 5 include a dust collection box 51 disposed below the synchronous belt and a cleaning element 54 for continuously cleaning the synchronous belt. The cleaning element 54 is disposed above the dust collection box 51. When the cleaning element 54 cleans the dust adhering to the synchronous belt, the dust falling from the synchronous belt falls into the dust collection box 51 below, thereby realizing the collection and unified cleaning of dust.

[0038] In one embodiment of the present invention, the cleaning component 54 includes a brush, the bristles of which contact the timing belt, and the bristles scrape off the dust on the surface of the timing belt using contact friction.

[0039] Reference Figure 6 As shown, in one embodiment of this utility model, the dust collection box 51 is provided with a drawer 52 inside, and the cleaning component 54 is disposed in the drawer 52. When the cleaning component 54 cleans the synchronous belt, the dust falling from the synchronous belt falls into the drawer 52 below. When cleaning the dust in the drawer 52, the worker uses the clearance opening of the dust collection box 51 to pull the drawer 52 out of the dust collection box 51 and clean the dust in the drawer 52 uniformly. Furthermore, the drawer 52 is also connected to a mounting base 53, and the cleaning component 54 can be detachably disposed in the mounting base 53. Since the cleaning component 54 is higher than the clearance opening and cannot pass directly through the clearance opening, the worker disassembles the cleaning component 54 before pulling out the drawer 52 to avoid the cleaning component 54 jamming the drawer 52.

[0040] Reference Figure 6 As shown, in one embodiment of this utility model, the dust collection box 51 is connected to the frame 1 via a connecting plate 511.

[0041] Reference Figure 3 As shown, in one embodiment of the present invention, the opening of the vacuum suction hole 31 is provided with an inlet chamfer 311. The inlet chamfer 311 is used to guide the dust falling onto the surface of the vacuum suction plate 3, guide the dust into the vacuum suction hole 31 efficiently, and reduce the dust residue on the surface of the vacuum suction plate 3.

[0042] Reference Figure 2 As shown, in one embodiment of this utility model, the vacuum suction hole 31 is located directly below the edge of the synchronous belt, precisely covering the dust generation area at the edge of the synchronous belt.

[0043] Reference Figure 2As shown, in one embodiment of this utility model, the vacuum suction plate 3 can be detachably connected to the frame 1 for quick replacement of the vacuum suction plate 3. The vacuum suction plate 3 is provided with a strip-shaped connecting hole 321 extending along the conveying direction. By using screws to pass through the strip-shaped connecting hole 321 and connect to the screw hole of the frame 1, the vacuum suction plate 3 and the frame 1 can be fixed. After loosening the screws, the position of the vacuum suction plate 3 can also be adjusted.

[0044] Reference Figure 1 As shown, in one embodiment of this utility model, multiple mechanisms are also included. The multiple conveying mechanisms include a first conveying mechanism 2a and a second conveying mechanism 2b disposed at the same height. Multiple pallets can be conveyed by the first conveying mechanism 2a and the second conveying mechanism 2b, which improves the pallet transfer efficiency. The first conveying mechanism 2a is disposed on one side of the second conveying mechanism 2b so that the robot arm 4 can perform loading and unloading operations on the pallets on the first conveying mechanism 2a and the second conveying mechanism 2b.

[0045] Reference Figure 1 As shown, in one embodiment of the present invention, the plurality of conveying mechanisms further includes a third conveying mechanism 2c, which is disposed below one of the first conveying mechanism 2a and the second conveying mechanism 2b. In this embodiment, the third conveying mechanism 2c is disposed below the first conveying mechanism 2a. The third conveying mechanism 2c is used to automatically return empty pallets. Empty pallets on the first conveying mechanism 2a and the second conveying mechanism 2b can be lowered onto the third conveying mechanism 2c by a lifting mechanism or by a worker.

[0046] Reference Figure 1 As shown, in one embodiment of this utility model, the conveying mechanism further includes a transmission shaft 2a3 and a drive motor 2a2 for driving the transmission shaft 2a3 to rotate. The synchronous belt includes a first synchronous belt 2a4 and a second synchronous belt 2a1, which are parallel and spaced apart, and are used to support and convey the two ends of the pallet respectively. The synchronous pulley includes a first synchronous pulley 2a7 and a second synchronous pulley 2a8, where the first synchronous pulley 2a7 meshes with the first synchronous belt 2a4 and the second synchronous pulley 2a8 meshes with the second synchronous belt 2a1. The two ends of the transmission shaft 2a3 are respectively connected to the first synchronous pulley 2a7 and the second synchronous pulley 2a8, so that the first synchronous pulley 2a7 and the second synchronous pulley 2a8 are driven by the transmission shaft 2a3. After the drive motor 2a2 drives the transmission shaft 2a3 to rotate, the transmission shaft 2a3 drives the first synchronous pulley 2a7 and the second synchronous pulley 2a8 to rotate, thereby realizing the conveying of the first synchronous belt 2a4 and the second synchronous belt 2a1.

[0047] Reference Figure 3As shown, in one embodiment of this utility model, a boss 32 protruding above the surface of the vacuum suction plate 3 is provided on one side of the vacuum suction plate 3. A strip-shaped connecting hole 321 is provided on the boss 32. When the screw passes through the strip-shaped connecting hole 321 to connect the frame 1, the surface of the boss 32 abuts against the frame 1, so that a gap is formed between the vacuum suction plate 3 and the timing belt, avoiding the vacuum suction plate 3 from directly touching the timing pulley.

[0048] The working principle of the dust-free pallet conveying device described in this utility model is as follows:

[0049] Full pallets are placed on the first conveyor mechanism 2a and the second conveyor mechanism 2b respectively. The drive motor 2a2 and the negative pressure device are turned on, and the synchronous belt starts to transport the pallets. The negative pressure device generates negative pressure, causing the vacuum suction plate 3 to start to absorb the dust generated by the synchronous belt. After the synchronous belt transports the full pallet to the material picking station, the robot arm 4 removes the material from the full pallet. The first conveyor mechanism 2a and the second conveyor mechanism 2b then transport the empty pallet to the end of the synchronous belt. At this time, the empty pallet is lifted by the lifting mechanism or by the worker and placed on the third conveyor mechanism 2c. The third conveyor mechanism 2c transports the empty pallet back to the loading station for continued loading. When the drawer 52 is full, the worker pulls it out for cleaning.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
