[0002] Currently, the plate cleaning is generally carried out by clamping and conveying the plate through a conveying device, and the plate is cleaned synchronously during the conveying process. The existing plate conveying device mainly comprises a base and a shaft, the shaft is provided with a plurality of pairs in the horizontal direction on the base, each pair of shafts is distributed in the vertical direction, a plurality of rollers are coaxially arranged on each shaft, the horizontal plate is clamped and conveyed through the two layers of rollers distributed in the vertical direction, and the upper shaft is generally supported by placing support blocks at the bottom of both ends thereof. In order to adapt to plates of different thicknesses, the height of the upper shaft is currently adjusted by replacing support blocks of different heights.

[0003] Since the cleaning device will continuously vibrate during the working process, the support blocks will be worn and moved, so that the height of the upper rollers changes slightly. When the conveying device conveys high-precision and easily-damaged plates, taking a load plate glass as an example, if the height of the upper rollers is increased, the load plate glass cannot be clamped; if the height of the upper rollers is decreased, the load plate glass is easily collided with the rollers during the conveying process, which causes the load plate glass to be broken, resulting in economic losses and affecting the production efficiency of the load plate glass. SUMMARY

[0004] The purpose of the present application is to provide a plate conveying mechanism and a plate cleaning device, so that the plate is not easily damaged during the conveying and cleaning process, thereby improving the plate yield, improving the equipment utilization rate, and reducing the production cost.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0036] The present embodiment provides a plate cleaning equipment, which is mainly used for cleaning plates with high precision. The present embodiment takes a plate as a carrier plate glass for example. In order to prevent the plate from being damaged, colliding with the equipment, and being stuck during conveying and cleaning, the cleaning equipment includes a plate conveying mechanism and a cleaning mechanism. The cleaning mechanism is arranged on the plate conveying mechanism. The cleaning mechanism is any mechanism that can clean glass in the prior art, such as a plurality of spray heads installed on the plate conveying mechanism to spray and clean the plate. Alternatively, two rotating roller brushes are arranged opposite to each other on the plate conveying mechanism to clean the plate. The plate conveying mechanism conveys the plate, and the cleaning mechanism cleans the plate during conveying.

[0037] Referring to Figure 1 The plate conveying mechanism described above includes a first base 1, a second base 2, and a connecting assembly 3. The first base 1 is arranged on the ground, the second base 2 is placed on the top of the first base 1, and the connecting assembly 3 connects the first base 2 and the first base 1.

[0038] With reference to Figure 1 , the first base 1 is provided with horizontal first rotating shafts 11, and each first rotating shaft 11 is coaxially and fixedly connected with a plurality of first rollers 12 along the axial direction of the first rotating shaft 11. In this embodiment, two first rotating shafts 11 are provided. The first rotating shafts 11 are driven to rotate by a motor.

[0039] With reference to Figure 1 , the second base 2 is provided with second rotating shafts 21 which are parallel to the first rotating shafts 11 and correspond to the first rotating shafts 11 one by one. Each second rotating shaft 21 is provided with a second roller 22 corresponding to each first roller 12.

[0040] In order to adapt the plate conveying mechanism to plates with different thicknesses, the distance between the second rotating shafts 21 and the first rotating shafts 11 is adjustable. The second base 2 is provided with cavities 23 corresponding to the end positions of the second rotating shafts 21. The two ends of the second rotating shafts 21 extend into the cavities 23 and are supported by the side walls of the bottom of the cavities 23. The cavities 23 are internally provided with space for the upward movement of the second rotating shafts 21.

[0041] The second rotating shafts 21 can have multiple fixed positions at different heights on the second base 2, thereby adjusting the distance between the second rotating shafts 21 and the first rotating shafts 11. Specifically, threaded bolts are connected to the two ends of the second rotating shafts 21. The axis of the threaded bolts is horizontal and perpendicular to the axis of the second rotating shafts 21. The threaded bolts are screwed into the second base 2 after penetrating the second rotating shafts 21. At this time, the distance between the second rotating shafts 21 and the first rotating shafts 11 is adjusted by changing the fixed position of the threaded bolts on the second base 2.

[0042] Further, the second base 2 is slidingly connected to the top of the first base 1. Specifically, a groove 13 is formed in the top of the first base 1. The bottom of the second base 2 is slidingly connected to the side wall of the groove 13, and a gap is left between the bottom of the second base 2 and the bottom of the groove 13. The groove 13 can limit the movement of the second base 2 and improve the stability of the second base 2.

[0043] It should be noted that the distribution direction of the first base 1 and the second base 2 can be adjusted according to the roughness of the surface of the plate. If the friction between the first rollers 12 and the second rollers 22 and the surface of the plate can overcome the gravity of the plate, the plate will not fall in the vertical state. The first base 1 and the second base 2 can also be distributed in the horizontal direction.

[0044] With reference to Figure 1 andFigure 2 The connecting assembly 3 is provided at least one at the end of each second rotating shaft 21, and one is taken as an example in the embodiment. Each connecting assembly 3 comprises a main body 31, a connecting piece 33, a first elastic piece 32 and a second elastic piece 34. The main body 31 is a vertically arranged cylinder. The entire outer wall of the main body 31 or the outer wall at the bottom end position is processed with external threads. A limiting head 311 is fixedly connected at the top end of the main body 31. The connecting piece 33 is a vertically arranged screw rod, which is coaxially connected at the bottom end of the main body 31. The first elastic piece 32 is elastically abutted between the limiting head 311 and the second rotating shaft 21. The second elastic piece 34 is elastically abutted between the bottom end of the main body 31 and the first base 1.

[0045] With reference to Figure 1 A through hole is formed in the side wall at the top of the cavity 23 to communicate the cavity 23 with the outside. The top end of the main body 31 movably penetrates the through hole, and a certain gap is left between the main body 31 and the side wall of the through hole. The axis of the main body 31 intersects the axis of the second rotating shaft 21. The middle part of the main body 31 slidably penetrates the second rotating shaft 21. Alternatively, the main body 31 can not penetrate the second rotating shaft 21, but directly connect the main body 31 and the second rotating shaft 21 through the first elastic piece 32. A threaded hole is formed in the side wall at the bottom of the cavity 23 to communicate the cavity 23 with the outside. The bottom end of the main body 31 is threadedly connected with the threaded hole on the second base 2.

[0046] With reference to Figure 1 After the main body 31 is threadedly connected with the second base 2, the positioning between the main body 31 and the second base 2 is realized. The second base 2 limited in the groove 13 is further locked by the one-way locking function of the threaded connection, so that the second base 2 cannot move relative to the main body 31 without rotation of the main body 31. Meanwhile, the relative position of the main body 31 and the second base 2 can be steplessly adjusted by rotating the main body 31, so that the position adjustment of the second base 2 is more convenient and accurate.

[0047] Further, the first elastic piece 32 is a spring, and the first elastic piece 32 is sleeved outside the main body 31. One end of the first elastic piece 32 abuts against the limiting head 311, and the other end abuts against the second rotating shaft 21. The first elastic piece 32 applies a downward elastic force to the second rotating shaft 21.

[0048] Alternatively, the first elastic piece 32 can be placed outside the main body 31, and one end of the first elastic piece 32 is fixedly connected with the main body 31, and the other end abuts against the second rotating shaft 21, so as to elastically abut against the second rotating shaft 21.

[0049] With reference to Figure 1The diameter of the connecting piece 33 is smaller than the diameter of the main body piece 31, so that a blocking part 312 is formed at the bottom end of the main body piece 31. A threaded hole is formed on the first base 1 corresponding to the bottom end of the connecting piece 33, and the bottom end of the connecting piece 33 is screwed with the threaded hole on the first base 1.

[0050] Further, the second elastic piece 34 is a spring, and the second elastic piece 34 is sleeved outside the connecting piece 33. One end of the second elastic piece 34 abuts against the blocking part 312, and the other end abuts against the first base 1. Alternatively, the second elastic piece 34 can be placed outside the connecting piece 33, and one end of the second elastic piece 34 is fixedly connected with the blocking part 312, and the other end abuts against the first base 1.

[0051] After the connecting piece 33 is screwed with the first base 1, the main body piece 31 is elastically abutted by the second elastic piece 34, so that the second elastic piece 34 always applies an upward force to the main body piece 31, so that the main body piece 31 is not easy to rotate in the working process, and the accuracy of the position of the second base 2 is ensured. Finally, the distance between the first roller 12 and the second roller 22 is accurate, and the distance has a space that can be elastically changed within a certain range.

[0052] With reference to Figure 1 and Figure 2 When the connecting assembly 3 is installed, the main body piece 31 is screwed with the second base 2, and the relative position between the main body piece 31 and the second base 2 is adjusted. Then, the connecting piece 33 is screwed with the first base 1. At this time, the second base 2 is limited by the groove 13, and the connecting piece 33 and the main body piece 31 rotate synchronously and move downward, so that the height of the second base 2 does not change.

[0053] Then, the connecting assembly 3 is debugged. The second elastic piece 34 and the first elastic piece 32 are in the compressed state by rotating the main body piece 31, so that the second elastic piece 34 continuously applies the elastic force to the main body piece 31, and the first elastic piece 32 continuously applies the elastic force to the second rotating shaft 21.

[0054] Since the second elastic piece 34 abuts against the main body piece 31, the main body piece 31 can be tightly prevented from loosening, so that when the main body piece 31 is rotated, the bottom end of the connecting piece 33 does not need to be screwed to the bottom of the threaded hole on the first base 1. This not only facilitates the installation and disassembly of the connecting assembly 3, but also leaves a space for the main body piece 31 to rotate and adjust. The height of the main body piece 31 can be adjusted by rotating the main body piece 31, and the working state of the first elastic piece 32 and the second elastic piece 34 can be adjusted.

[0055] With reference to Figure 1In the working process of the plate conveying mechanism, the plate to be conveyed is placed between the second roller 22 and the first roller 12 at the head end of the plate conveying mechanism, and the plate is pushed forward by manual or mechanical hand. Since the height of the first roller 12 is fixed, one side of the plate abuts against the second roller 22, and the plate applies an upward pushing force to the second roller 22, so that the second roller 22 moves upward against the elastic force of the first elastic member 32.

[0056] At this time, the plate is elastically clamped between the second roller 22 and the first roller 12, and when the first roller 12 rotates, the plate is conveyed, so that the plate smoothly passes through all the second rollers 22 and is not easy to collide with the second rollers 22. The generation of broken pieces of the plate, the impact on the equipment, the jamming and the like are reduced, so that the normal production is not affected. After the plate passes through the second roller 22, the second rotating shaft 21 is reset under the elastic force of the first elastic member 32, and the second roller 22 on the second rotating shaft 21 is also reset.

[0057] Obviously, the above embodiments of the present application are merely exemplary for the purpose of clarity and are not intended to limit the embodiments of the present application. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of the present application. It is unnecessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
