[0026] Referring to the drawings, Figures 1 to 7 The film tearing machine in the embodiment includes a working rack 1, a profile support 3, at least one display screen bearing plate 4 which is detachable and located on the profile support 3, and a turnover mechanism 2. The display screen bearing plate 4 is fixed on the profile support 3 by screw locking. Multiple display screen bearing plates 4 can be arbitrarily assembled on the profile support 3 to adapt to the film tearing of screens of different sizes, thereby improving the applicability of the film tearing machine.

[0027] The turnover mechanism 2 comprises a turnover driving member 21 and a turnover fixing shaft 22, the turnover driving member 21 can drive the profile support 3 arranged on the turnover fixing shaft 22 to turn around any angle, the profile support 3 is horizontally placed in the initial state, the screen to be peeled is placed on the profile support 3, after the adsorption mechanism 5 adsorbs and the heating assembly 6 heats, the turnover driving member 21 drives the turnover fixing shaft 22 to rotate by 90 degrees, the screen is turned from the horizontal state to the vertical state, the staff can conveniently peel the protective film on the screen from top to bottom, which is more time-saving and labor-saving than peeling the film on the horizontal plane.

[0028] A plurality of negative pressure adsorption holes 51 are arranged on the top of the display screen bearing plate 4, when the negative pressure adsorption holes 51 are vacuumized, the screen can be adsorbed on the display screen bearing plate 4, so as to avoid falling of the screen in the subsequent film peeling process.

[0029] In some embodiments, referring to the accompanying drawings, Figure 1 The display screen bearing plate 4 is provided with four pieces along the length direction of the profile support 3, the density of the negative pressure adsorption holes 51 arranged on the display screen bearing plate 4 away from the hot air gun 7 is greater than that of the negative pressure adsorption holes 51 arranged on the display screen bearing plate 4 close to the hot air gun 7, when peeling the film, the staff peels from the upper right corner of the screen, the greater density of the negative pressure adsorption holes 51 makes the adsorption force of the display screen bearing plate 4 at this position greater, which can further adsorb the screen on the display screen bearing plate 4, avoiding the screen from moving or falling to affect the film peeling effect.

[0030] At least one heating assembly 6 is arranged at the bottom of each display screen bearing plate 4, to heat the protective film on the screen. The heat generated by the heating assembly 6 is transmitted to the protective film on the screen through the display screen bearing plate 4, the protective film can weaken the adhesion of the film after being heated for a long time, and then the edge or local part is peeled off from the screen, which is convenient for subsequent film peeling operation.

[0031] In some embodiments, four heating assemblies 6 are arranged on the lower surface of each display screen bearing plate 4, to make the heat received by the screen uniform.

[0032] The adsorption mechanism 5 comprises at least one negative pressure nozzle mounting plate 52 mounted at the bottom of the display screen bearing plate 4, a plurality of negative pressure nozzles 53 are fixedly arranged on each negative pressure nozzle mounting plate 52, a groove is arranged at the position corresponding to the negative pressure nozzle mounting plate 52 at the bottom of the display screen bearing plate 4, and a gas containing cavity 54 for gas flowing into the negative pressure adsorption hole 51 is formed between the groove and the negative pressure nozzle mounting plate 52.

[0033] The negative pressure suction nozzle mounting plate 52 is used to support the installation of the negative pressure suction nozzle, and one end of the negative pressure suction nozzle away from the negative pressure suction nozzle mounting plate 52 is connected with the air suction pump. When the screen to be torn is placed on the surface of the display screen bearing plate 4, the air suction pump works to suck the air in the display screen bearing plate 4 through the negative pressure suction nozzle, and the screen is firmly fixed by the negative pressure generated by the air suction to avoid rotating in the tearing process and affecting the tearing efficiency.

[0034] In some embodiments, the negative pressure suction nozzle mounting plate 52 is arranged along the width direction of the profile bracket 3, and is specifically arranged at the bottom side of the display screen bearing plate 4. The groove can completely cover the negative pressure suction nozzle.

[0035] It should be noted that the number of the suction mechanism 5 can be changed according to the density of the negative pressure suction holes 51 opened on the display screen bearing plate 4 to ensure that sufficient negative pressure for suction of the screen is formed on the surface of the display screen bearing plate 4.

[0036] A plurality of negative pressure channels 56 corresponding to each row of negative pressure suction holes 51 are opened in the display screen bearing plate 4 in a direction perpendicular to the negative pressure suction nozzle mounting plate 52, and one end of the negative pressure channel 56 close to the negative pressure suction nozzle mounting plate 52 extends to the inside thereof. The negative pressure channel 56 can converge the gas in each corresponding negative pressure suction hole 51 when the vacuum is sucked to improve the efficiency of vacuum suction and form negative pressure on the surface of the display screen bearing plate 4. At the same time, the end of each negative pressure suction hole 51 is in communication with the corresponding negative pressure channel 56, which can ensure that the negative pressure on the surface of the display screen bearing plate 4 is uniform.

[0037] In some embodiments, a plurality of horizontal arc-shaped grooves 55 in communication with the negative pressure channels 56 are opened in the gas containing cavity 54 along the width direction thereof, so that the gas in the negative pressure channel 56 is sucked into the gas containing cavity 54 by the air suction pump and then flows out of the negative pressure suction nozzle.

[0038] The number of each group of negative pressure suction nozzles is not limited and can correspond to the negative pressure channels 56 opened on the display screen bearing plate 4 one by one.

[0039] It should be noted that the display screen bearing plate 4 is sealed around to avoid air leakage of the display screen bearing plate 4 when the negative pressure is sucked, which affects the suction effect of the screen.

[0040] The turnover mechanism 2 further comprises two symmetrical turnover fixing seats 23 and a plurality of connecting fixing seats 24. The turnover fixing seat 23 is vertically arranged on the working rack 1, the two ends of the turnover fixed shaft 22 in the length direction are connected with the turnover fixing seat 23 through bearings, and the turnover driving member 21 is fixedly arranged on the turnover fixing seat 23, and the driving end thereof is fixedly connected with one end of the turnover fixed shaft 22.

After the connection upper part and the connection lower part are connected by a screw, the fixing groove I and the fixing groove II form a limited space for clamping the turnover fixing shaft 22.

[0044] It should be noted that the clamping mode between the connection fixing base 24 and the turnover fixing base 23 is not limited, and any known mechanical mechanism that can fix it on the turnover fixing shaft 22 can be used, which will not be described in detail here.

[0045] The heating assembly 6 comprises a support plate 61 detachably connected to the display screen bearing plate 4 and a heating plate 62. The upper surface of the support plate 61 is provided with a mounting groove 64, and the heating plate 62 is located in the mounting groove 64. The support plate 61 supports the heating plate 62, which can be sealed between the mounting groove 64 and the lower surface of the display screen bearing plate 4 to prevent heat loss and affect the heating effect of the protective film on the screen.

[0046] In some embodiments, the support plate 61 is connected to the display screen bearing plate 4 by a plurality of screws around the support plate 61, so that the staff can maintain and replace the heating plate 62 located between the support plate 61 and the display screen bearing plate 4. A clearance groove 63 is provided in the height direction of the support plate 61. The screw can pass through the clearance groove 63 and fix the heating plate 62 and the display screen bearing plate 4.

[0047] The support plate 61 is a mica plate, and the heating plate 62 is a graphene heating plate 62. The mica plate not only supports the heating plate 62, but also prevents heat loss and prevents the staff from being touched and causing burns. The heating plate 62 is provided with a thermocouple, which can adjust the heating temperature of the screen.

[0048] The workbench 1 is provided with an external controller, a display screen and a hot air gun 7. The hot air gun 7 can assist in film tearing. If the protective film on the screen is still difficult to peel after heating, the staff can hold the hot air gun 7 to heat the surface of the corresponding area to weaken the adhesion of the protective film, so that the protective film is conveniently peeled.

[0049] In some embodiments, the workbench 1 is provided with casters at the bottom of four corners, facilitating the carrying of the film tearing machine.
