[0090] Specifically, the double-sided film peeling device provided in this embodiment first loads the glass 100 with the back side facing upward to the back film peeling station 101, and the film peeling mechanism 3 pries up one end of the protective film on the back side of the glass 100; then the transfer device drives the glass 100 to move to the back film peeling station 102, and the film peeling device 4 tears off the protective film on the back side of the glass 100; then the transfer device drives the glass 100 to move to the front film peeling station 103, and the glass flipping mechanism 5 drives the glass 100 to flip so that its front side faces upward, and the other film peeling mechanism 3 One end of the protective film on the front side of the glass 100 is pried up; then the transfer device drives the glass 100 to move to the front film tearing station 104, and another film tearing device 4 tears off the protective film on the front side of the glass 100; then the transfer device drives the glass 100 to move to the flipping station 105, and another glass flipping mechanism 5 drives the glass 100 to flip it to restore the state of the reverse side facing up and then unload the material, thus completing the double-sided film tearing process of the glass 100, realizing the automation of the double-sided film tearing operation of the glass 100, and improving the production efficiency and standardization level.

[0091] Optional, such as Figure 4 As shown, the glass transfer device 2 includes a transfer frame 21, a longitudinal plate 22, a transverse plate 23 and a transfer fixture.

The film lifting transverse displacement cylinder 32 can drive the film lifting sheet 31 to move in the horizontal direction. The film lifting lifting motor 33 is used to drive the film lifting transverse displacement cylinder 32 to move up and down. Specifically, after the first positioning mechanism 7 clamps the glass 100 to be film lifted, the film lifting transverse displacement cylinder 32 drives the film lifting sheet 31 to move in the horizontal direction to insert into the gap between the glass 100 and the protective film thereon; then the film lifting lifting motor 33 drives the film lifting sheet 31 to rise, so as to drive one end of the protective film above it to tilt upward, thereby realizing the film lifting operation.

Furthermore, the output end of the film lifting motor 33 is also connected to a film lifting reducer 39, and the film lifting motor 33 is connected to the ball screw structure through the film lifting reducer 39.

[0097] Further, such as Figure 6 and Figure 7 As shown, the film-tearing device 4 includes a film-tearing frame 41 and a film-tearing mechanism 42. The film-tearing mechanism 42 is slidably arranged on the film-tearing frame 41 in the horizontal direction. The film-tearing mechanism 42 includes a glue-clamping component 421, a compacting component 422 and a film-tearing lifting component 423.

[0148] Optional, such as Fig.17 As shown, the cabinet 1 is also provided with a tray unloading device 10, and the tray unloading device 10 is provided with a unloading station and a tray stacking station. The tray unloading device 10 includes an unloading conveying mechanism and a tray stacking mechanism 1003. The unloading conveying mechanism is used to convey the tray along the X-axis direction; the tray stacking mechanism 1003 is provided at the tray stacking station, and is used to stack the trays conveyed to the tray stacking station one by one upward for recovery. Under the coordinated action of the loading conveying mechanism and the unloading conveying mechanism, the tray can be sequentially conveyed along the tray separation station, the loading station, the unloading station and the tray stacking station.

[0149] Optional, such as Fig.18 As shown, the stacking mechanism 1003 includes a supporting assembly 10031 and a first-stage lifting assembly 10032. The supporting assembly 10031 can switch between an avoidance state that allows the material tray to move vertically and a supporting state that carries the material tray; the first-stage lifting assembly 10032 can drive the material tray to pass through the supporting assembly 10031 in the vertical direction.

[0150] Specifically, the stacking mechanism 1003 includes a supporting assembly 10031 and a first-stage lifting assembly 10032. The supporting assembly 10031 can switch between an avoidance state allowing the material tray to move vertically and a supporting state for carrying the material tray. The first-stage lifting assembly 10032 can drive the material tray to pass through the supporting assembly 10031 in a vertical direction.

[0151] Further, the supporting assembly 10031 includes a supporting bracket 100311 and a second supporting plate 100312, the supporting bracket 100311 is installed on the cabinet 1, the second supporting plate 100312 is connected to the supporting bracket 100311 around a horizontal axis, and the movable end of the second supporting plate 100312 can rotate above the horizontal plane. When the second supporting plate 100312 is in a supporting state, the second supporting plate 100312 is in a horizontal position. The first-level lifting assembly 10032 includes a third lifting cylinder 100321 and a second lifting plate 100322. The third lifting cylinder 100321 is installed on the cabinet 1, and its output end is arranged upward. The second lifting plate 100322 is installed on the output end of the third lifting cylinder 100321, and the third lifting cylinder 100321 can drive the second lifting plate 100322 to rise and fall in the vertical direction.

[0152] Specifically, in the initial state, the second supporting plate 100312 is in a supporting state, and the third lifting cylinder 100321 is in a retracted state. At this time, the height of the second supporting plate 100322 is lower than the height of the supporting material tray of the unloading conveying mechanism. When the material tray is conveyed to the recycling station, the third lifting cylinder 100321 extends upward, driving the second lifting plate 100322 to move upward, and at the same time driving the material tray to rise. The rising material tray interferes with the second supporting plate 100312, driving the second supporting plate 100312 to rotate to a yielding state. If there is already a material tray placed on the second supporting plate 100312, the existing material tray will be lifted up together. After the material tray passes, the second supporting plate 100312 rotates downward under the action of gravity and returns to the supporting state. Then the third lifting cylinder 100321 retracts, and the material tray is placed on the second supporting plate 100312. The second lifting plate 100322 is separated from the material tray and gradually descends to below the height of the material tray supported by the unloading conveying mechanism, completing the recycling and stacking process of a material tray. This cycle can be repeated to achieve the recycling and stacking of the material trays that are full of workpieces one by one.

[0153] Optionally, four supporting assemblies 10031 are provided, with two supporting assemblies 10031 arranged side by side on each side of the unloading conveying mechanism. The four supporting assemblies 10031 jointly support the stacked material trays to be recycled, thereby improving stability.

[0154] Optionally, the unloading conveying mechanism includes an unloading conveying motor and two synchronous pulley assemblies arranged side by side. The unloading conveying motor is installed on the cabinet 1. The output end of the unloading conveying motor is simultaneously connected to the two synchronous pulley assemblies to drive the two synchronous pulley assemblies to rotate synchronously. Specifically, the conveyed material tray is placed on the synchronous belt in the synchronous pulley assembly and driven by the synchronous belt. The secondary lifting assembly 922 and the primary lifting assembly 10032 are both arranged between the synchronous belts of the two synchronous pulley assemblies and can pass between the two synchronous belts arranged side by side in the vertical direction.

[0155] Optionally, the tray unloading device 10 also includes a unloading centering mechanism, which is arranged at the unloading station.

The unloading centering cylinder is installed on the cabinet 1 and is located on the other side of the unloading conveying device. The unloading centering movable plate is movably connected to the output end of the unloading centering cylinder. The unloading centering cylinder can drive the unloading centering movable plate to move along the Y-axis direction to clamp the tray on the unloading station between the unloading centering fixed plate and the unloading centering movable plate to ensure that the tray is in a preset position when the glass 100 is unloaded onto the tray.

[0156] Optionally, the double-sided film tearing device further includes two glass loading and unloading devices 11, both of which are arranged on the cabinet 1, one of the two glass loading and unloading devices 11 is arranged between the reverse film stripping station 101 and the loading station, and the other is arranged between the flipping station 105 and the unloading station, and the glass loading and unloading device 11 includes a loading and unloading frame, a longitudinal moving frame 112, a lifting frame 113 and a loading and unloading assembly.

The two material picking and placing lifting cylinders 115 are respectively installed on the two output ends of the two-way cylinder 114, and the output ends of the two material picking and placing lifting cylinders 115 are both vertically arranged downward. The output ends of the material picking and placing lifting cylinders 115 are connected to the material picking and placing suction cup 116 through the elastic buffer 117. The setting of the elastic buffer 117 can reduce the impact of the material picking and placing suction cup 116 on the glass 100 when picking and placing materials. The material picking and placing suction cup 116 is connected to an external vacuum pump to suck the glass 100 under the drive of the vacuum pump. Through the telescopic effect of the bidirectional cylinder 114, the distance between the two glasses 100 lifted by the material loading and unloading assembly can be adjusted to solve the problem that the distance between the two glasses 100 at the workstations on the cabinet 1 and on the material tray is not equal.

[0158] In this embodiment, two pick-up and put-down suction cups 116 are installed on the output end of each pick-up and put-down lifting cylinder 115.
