DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the utility model with reference to the drawings and embodiments:

[0020] An automatic clamping device for plexiglass, see Figures 1 to 3, including a base 1. A bracket 11 is vertically welded to the upper surface of the base 1. It also includes two groups of clamping arms 13. A clamping plate 3 is provided at the clamping end of the clamping arms 13. First connection grooves 12 are horizontally penetrated and opened above and below the bracket 11. The two groups of clamping arms 13 are respectively hinged to the two groups of first connection grooves 12. The bracket 11 is in an inverted L shape, and the two groups of brackets 11 are symmetrically arranged; Adjusting mechanism: used for adjusting the use angles of the two groups of clamping arms 13. The adjusting mechanism includes a piston cylinder 14. A piston 15 is slidably connected inside the piston cylinder 14. A telescopic rod 16 is vertically and fixedly installed in the middle of the upper surface of the piston 15. A second connection groove 17 is opened at one end of the clamping arm 13 away from the clamping plate 3. The bottom end of the piston cylinder 14 and the telescopic end of the telescopic rod 16 are respectively hinged to the second connection grooves 17 of the two groups of clamping arms 13. Two air inlet hoses 18 and an air outlet pipe 2 are respectively fixedly installed on both sides of the lower end of the piston cylinder 14. The air outlet end of the air inlet hose 18 is communicated with the bottom end inside the piston cylinder 14. The air inlet end of the air outlet pipe 2 is communicated with the bottom end inside the piston cylinder 14. First solenoid valves 22 and second solenoid valves 23 are respectively arranged inside the air inlet hose 18 and the air outlet pipe 2.

[0021] Place the clamping end of the adjusted plexiglass between the upper and lower two clamping plates 3. Connect the air inlet end of the air inlet hose 18 to the air outlet of the corresponding air pump. Control the first solenoid valve 22 to open through the controller 37. Air can be inflated into the piston cylinder 14 through the air inlet hose 18. As the gas pressure inside the piston cylinder 14 increases, it can push the piston 15 to move upward inside the piston cylinder 14, thereby pushing the telescopic rod 16 to move upward. Since the telescopic end of the telescopic rod 16 and the bottom end of the piston cylinder 14 are respectively hinged to the two groups of clamping arms 13, and the two groups of clamping arms 13 are hinged to the bracket 11, the telescopic rod 16 and the piston cylinder 14 can push the clamping ends of the two groups of clamping arms 13 to move relatively, thereby driving the two clamping plates 3 to clamp the plexiglass.

[0022] Specifically, refer to Figures 1 to 3 , a spring 21 is arranged above the piston 15. The spring 21 is sleeved outside the telescopic rod 16. The two ends of the spring 21 are respectively fixedly connected to the inner wall of the top end of the piston cylinder 14 and the piston 15. The sizes of the piston cylinder 14 and the telescopic rod 16 are matched.

[0023] When it is necessary to remove the plexiglass, control the first solenoid valve 22 to close through the controller 37, and at the same time control the second solenoid valve 23 to open, so as to discharge the high-pressure air inside the piston cylinder 14. Since a spring 21 is arranged above the piston 15, through the elastic force of the spring 21, it can push the piston 15 to move downward and reset inside the piston cylinder 14, and further can automatically adjust the two groups of clamping arms 13 to reset, so that the two clamping plates 3 move in the reverse direction and loosen the plexiglass.

[0024] Furthermore, refer to Figures 1 to 3, Detection mechanism: It is used to detect and control the clamping force of two groups of clamping plates 3 on plexiglass. The detection mechanism includes a pressure sensor 36. A limiting groove 32 is opened inside the clamping end of the clamping arm 13. A limiting block 33 is slidably connected inside the limiting groove 32. A connecting strip 34 is vertically fixedly installed on the bottom side of the limiting block 33. The pressure sensor 36 is fixedly connected to the inner wall of the limiting groove 32 away from the clamping plate 3. The limiting block 33 is movably connected to the pressure sensor 36. A sliding groove 35 is opened on the inner wall of the limiting groove 32 close to the clamping plate 3. The connecting strip 34 is slidably connected to the sliding groove 35. A controller 37 is fixedly connected to the front side of the bracket 11. The data output end of the pressure sensor 36 is connected to the data input end of the controller 37. The signal output end of the controller 37 is connected to the signal input end of the first solenoid valve 22.

[0025] By sliding the limiting block 33 and the limiting groove 32, when the clamping plate 3 clamps the plexiglass, the pressure sensor 36 can detect the pressure of the limiting block 33, so as to detect the clamping force of the clamping plate 3 on the plexiglass. When the clamping force reaches the threshold value of the pressure sensor 36, the pressure sensor 36 transmits the data to the controller 37. Further, the controller 37 can automatically control the first solenoid valve 22 to close, so as to control the clamping force of the clamping plate 3 on the plexiglass, and can solve the problem that the existing plexiglass clamping device cannot accurately control the clamping force of the clamping plate 3 on the plexiglass.

[0026] It should be noted that, see Figures 1 to 3 , A connecting block 31 is fixedly installed in the middle of the side of the clamping plate 3 close to the clamping arm 13. One end of the connecting strip 34 outside the limiting groove 32 is hinged to the connecting block 31.

[0027] Through the clamping plate 3 at the clamping end of the clamping arm 13, the stress area of the plexiglass can be increased, and the clamping effect of the plexiglass can be further improved. By hinging the connecting block 31 outside the clamping plate 3 with the connecting block 31, the use angle of the clamping plate 3 can be adjusted to make the clamping plate 3 fit the surface of the plexiglass.

Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.
