[0030] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0031] This application discloses a pneumatic tray quick-change device.

[0032] Reference Figure 1-3 A pneumatic tray quick-change device includes a mounting plate 1, a piston assembly 2 installed on the inner wall of the mounting plate 1, and a mounting sleeve 3 installed on the top outer wall of the mounting plate 1. The mounting plate 1 has a T-shaped cross-section, and a fixing sleeve 5 is fixedly connected to the bottom outer wall of the mounting plate 1. The outer wall of the mounting plate 1 has multiple equally spaced circular openings, and the inner wall of each of the multiple circular openings is provided with steel balls 13. The mounting sleeve 3 is fitted onto the outer wall of the mounting plate 1, and the steel balls 13 are in contact with the inner wall of the mounting sleeve 3. The mounting plate 1 has a T-shaped cross-section, and the top of the mounting plate 1 is provided with a protruding pipe. The steel balls 13 are installed on the protruding pipe, and the mounting sleeve 3 is also fitted onto the protruding pipe. When the steel balls 13 extend, they press against the mounting sleeve 3. The arrangement of multiple steel balls 13 facilitates the effective pressing and fixing of the mounting sleeve 3, thereby facilitating the quick installation and removal of the mounting sleeve 3 by controlling the movement of the steel balls 13.

[0033] In use, the installation plate 1 facilitates the installation of the piston assembly 2, and the cooperation between the piston assembly 2 and the installation plate 1 facilitates the quick assembly and disassembly of the installation sleeve 3. The steel ball 13 inside the round opening of the installation plate 1 helps to fix and tighten the installation sleeve 3.

[0034] Reference Figure 4-6 The piston assembly 2 includes a piston 11 slidably connected to the inner wall of the fixed sleeve 5, and a piston rod 7 is fixedly connected to the center of one side of the outer wall of the piston 11. The outer wall of the piston rod 7 has a tapered annular groove 8 and an annular groove 14. The top outer wall of the piston rod 7 has multiple equidistant jet holes 12. The piston rod 7 has an air chamber 15 inside, which, together with the jet holes 12, facilitates air blowing to clean the surface of the mounting plate 1. The jet holes 12 and the air chamber 15 are connected. The piston rod 7 is connected to the air chamber 15 via an air hole 9. The piston rod 7 is installed via the piston 11. When the piston 11 slides, it directly drives the piston rod 7 to move. When the piston rod 7 moves, it works with the annular groove 8 to drive the steel ball 13 to move, thereby facilitating the clamping and fixing of the mounting sleeve 3. The air jet hole 12 on the piston rod 7 facilitates the cleaning of the surface of the mounting plate 1. The air chamber 15 and the air hole 9 in the piston rod 7 work together to facilitate the delivery of auxiliary gas to the air jet hole 12, thereby facilitating the cleaning of the surface of the mounting plate 1.

[0035] Reference Figure 4-6 Multiple equally spaced mounting slots 16 are provided on the top outer wall of piston 11 and the bottom outer wall of mounting plate 1. Springs 10 are fixedly connected to the inner walls of two opposing mounting slots 16. The mounting slots 16 assist the springs 10 in installation, assisting the piston 11 in movement and effectively preventing the springs 10 from shifting. Three equally spaced air holes 6 are provided on the bottom outer wall of mounting plate 1. An air hole 9 is provided on one side of the outer wall of mounting plate 1, communicating with one of the air holes 6. An air passage is provided in mounting plate 1, communicating with the air hole 6, and one end of the air passage is fixedly connected to... A sealing plug 4 is connected, and multiple springs 10 are set between the piston 11 and the mounting plate 1 to facilitate the movement of the piston 11. When the air hole 1 6 is inflated, it works with the air hole 2 9 to facilitate blowing air to clean the surface of the mounting plate 1. The other two air holes 1 6 are set to facilitate the inflation and deflation of the fixed sleeve 5 on the mounting plate 1. The sealing plug 4 blocks one end of the air chamber. When the air hole 1 6 is inflated, it directly blows air through the air chamber conveyor belt air jet hole 12 to assist in blowing air onto the surface of the mounting plate 1. The airflow blows out the impurities around the mounting plate 1 directly.

[0036] The implementation principle of the pneumatic tray quick-change device in this application embodiment is as follows: When using the device, when fixing the mounting sleeve 3, the mounting sleeve 3 is first fitted onto the outer wall of the mounting plate 1. At this time, one of the air holes 6 is inflated. When inflated, the piston 11 is driven to move down under the action of air pressure. When the piston 11 moves down, it directly pulls the piston rod 7 down. When the piston rod 7 moves down, it pushes out the steel ball 13. When the steel ball 13 is pushed out, it presses the mounting sleeve 3, thus making it easier to fix the mounting sleeve 3. When removing the mounting sleeve 3, the other air hole 6 is inflated to drive the piston 11 to reset. At this time, the locking of the steel ball 13 is released, so the mounting sleeve 3 can be directly removed. At the same time, when the piston 11 resets, the spring 10 assists the piston 11 in its action. When it is necessary to clean the mounting plate 1, air is inflated from the air hole 6 and gas is delivered into the air chamber 15 through the air hole 9. Finally, the surface of the mounting plate 1 is cleaned by blowing air through the jet hole 12.

[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.
