Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of glass film tearing, and particularly relates to a glass film tearing device. BACKGROUND

[0002] Glass is a material widely used in industry at present. In order to protect the surface of glass, a protective film is covered on the surface of glass. When the glass is processed subsequently, the protective film on the surface of glass needs to be torn off. Since the glass is covered with a large-area film and the glass needs to be cut into a specified size after being covered with the film, the edge of the protective film is flush with the edge of the glass, which makes it difficult to tear off the protective film. In order to pull up the edge of the protective film, a film-sticking adhesive is generally pasted on the protective film, and the film-sticking adhesive is pulled to tear off the protective film on the glass.

[0003] A film tearing mechanism is disclosed in Chinese patent document CN114162417A, and an automatic online film tearing mechanism is specifically disclosed, which timely and reliably completes film tearing at a cutting front station. The film tearing mechanism adopts an easy-to-tear paste film-sticking adhesive. After the film-sticking adhesive is taken by a chuck unit, the film-sticking adhesive is moved to a tearing starting point. The film-sticking adhesive is stuck to the protective film on the corner of the glass by a rolling unit. The film-sticking adhesive is rolled by a rolling roller three times in succession before and after, so that the film-sticking adhesive is more reliably adhered to the protective film. The film tearing mechanism is slowly lifted to pull up the film-sticking adhesive to a height of 10 mm. The film tearing mechanism is accelerated to lift and move obliquely backward at the same time. The film-sticking adhesive pulls the protective film to tear the film along the diagonal direction. When the moving distance is about 500 mm, the film clamping arm is lowered and clamped to the protective film. The film clamping device pulls the protective film to move quickly backward along the diagonal direction to complete film tearing. An easy-to-tear paste feeding mechanism is also disclosed, which comprises a supporting seat, a feeding wheel, a winding wheel, a supporting roller, a winding motor and a tearing platform fixed on the supporting seat. The feeding wheel is wound with a material belt to which the easy-to-tear paste is adhered. The outer end of the material belt is fixed to the winding wheel. The feeding wheel is connected with a damping mechanism which is commonly used by those skilled in the art. The winding wheel is connected with the output end of the winding motor. The supporting roller is arranged above the feeding wheel and the winding wheel. The tearing platform is arranged between the two supporting rollers. The tearing platform is provided with a fiber sensor for sensing the position of the easy-to-tear paste. When the winding wheel is driven to rotate by the winding motor, the material belt is pulled out. The material belt is tensioned by the two supporting rollers and laid flat on the tearing platform. The film tearing mechanism clamps and tears off the easy-to-tear paste adhered to the material belt on the tearing platform. The position of the easy-to-tear paste can be detected by the fiber sensor. When the previous easy-to-tear paste is clamped by the film tearing mechanism, the fiber sensor transmits a signal to the controller. The winding motor is driven to rotate the winding wheel by the controller to realize timely replacement of the easy-to-tear paste.

[0004] However, the scheme described in the above patent document is to transport the glass to the conveying platform, and after the glass is positioned, the film-stripping tape feeding mechanism transports the film-stripping tape to the specified position, and the film-stripping clamp clamps the film-stripping tape on the edge of the glass, and the film-stripping tape is moved by the film-stripping clamp to complete the film-stripping, and the scheme needs to keep the glass stationary, and the film-stripping efficiency is low.

[0029] In one embodiment of the present application, the present embodiment provides a glass film tearing device for tearing off a protective film on the surface of glass. Please refer to Figures 1-5, specifically, the glass film tearing device comprises a rack 100, a conveying line 200 and a film tearing device 300. The conveying line 200 is arranged at the upper end of the rack 100, and has a conveying surface for conveying glass. Specifically, the conveying line 200 is a belt conveying line, and is a belt conveying line composed of multiple synchronous belts. The top end and / or the bottom end of the conveying line 200 is provided with the film tearing device 300. Specifically, the film tearing device 300 is arranged at the top side or the bottom side of the conveying line 200, or at both the top side and the bottom side of the conveying line 200, according to the actual film tearing requirement of the glass. When the upper surface of the glass needs to be torn, the film tearing device 300 is arranged at the top side of the conveying line 200; when the lower surface of the glass needs to be torn, the film tearing device 300 is arranged at the bottom side of the conveying line 200; and when both surfaces of the glass need to be torn, the film tearing device 300 is arranged at both the top side and the bottom side of the conveying line 200. The film tearing device 300 comprises a label stripping mechanism 310 and a film tearing clamping mechanism 320. The rack 100 comprises a first end 101 and a second end 102, the first end 101 is located at the front end of the conveying line 200, and the second end 102 is located at the tail end of the conveying line 200. The label stripping mechanism 310 is arranged at the first end 101 of the rack 100, and comprises a label stripping knife plate 311. The free end of the label stripping knife plate 311 faces the conveying line 200, and is used to tear off the label and make one end of the label stripped face the conveying line 200. Specifically, a plurality of labels (easy-to-tear labels) are continuously attached on a carrier tape, the carrier tape is arranged on the label stripping mechanism 310, and the carrier tape passes around the end of the label stripping knife plate 311. When the carrier tape is pulled by the label stripping mechanism 310, the labels can be gradually stripped. During the conveying of the glass, the end of the glass collides with the stripped label, so that the label is attached to the glass, and one end of the label protrudes from the end of the glass; the film tearing clamping mechanism 320 is arranged at the second end of the rack 100, and comprises a clamping piece 330 for clamping the end of the label protruding from the glass, so that the label pulls up the protective film on the surface of the glass.

[0030] Specifically, the glass film tearing device, at the end of the glass conveying to the conveying line 200, the label (easy-to-tear label) is peeled off by the label peeling knife plate 311 of the label peeling mechanism 310, and the end of the label peeled off is towards the conveying line and extends to the end of the glass. When the glass is conveyed to the conveying line 200, the end of the glass will touch the peeled label and push the label to move together, so that the whole label can be completely peeled off. When the label is pushed or pulled by the moving glass, the other end of the label is still attached to the carrier film of the label peeling mechanism 310, so that the label is pulled to an inclined state. After the label is completely peeled off, the label is adsorbed and attached to the surface of the glass. After the label is attached to the surface of the glass, the label is gradually conveyed to the conveying line 200, and the glass is conveyed to the second end of the rack by the conveying line 200. When the label attached to the glass is conveyed to the bottom end of the clamping piece, the end of the label is clamped by the clamping piece 330, and the label is pulled and the protective film on the glass is lifted by the label, so that the protective film on the glass can be pulled up. Therefore, when the conveying line 200 continues to push the glass to convey, the protective film attached to the surface of the glass can be completely peeled off. Therefore, the glass film tearing device can realize that the title is attached to the surface of the glass during conveying, and the protective film on the surface of the glass can be peeled off during conveying, so as to provide the efficiency of glass film tearing.

[0031] Further, the first photoelectric switch is arranged at the first end 101 of the rack 100, which is used to detect whether the glass is conveyed to the end of the conveying line 200. The second photoelectric switch is arranged at one side of the label peeling knife plate 311, which is used to detect the position of the label on the label peeling mechanism 310, so that the label peeling mechanism 310 can control the peeling of the label. The third photoelectric switch is further arranged at the second end 102 of the rack 100, which detects the label at the end of the glass through the third photoelectric switch hole, so that the clamping piece 330 of the film tearing clamping mechanism 320 can clamp the label to tear off the protective film.

[0032] Further, with reference to Figure 4 and Figure 5The film tearing and clamping mechanism 320 further comprises a blowing mechanism 340 arranged at one side of the clamping member 330. The blowing mechanism 340 is connected to a gas supply device and is used to blow gas to the end of the label adhered to the end of the glass, so that the end of the label is folded towards the clamping member 330, and the clamping member 330 can clamp the label. Specifically, when the film tearing device 300 is arranged at the top side of the conveying line 200, the blowing mechanism 340 is arranged at the bottom end of the clamping member 330, so that the label adhered to the end of the glass can be blown upwards to the clamping position of the clamping member 330, so that the clamping member 330 can smoothly clamp the end of the label. In order to facilitate the clamping of the label by the film tearing and clamping mechanism 320, the blowing mechanism 340 can be arranged on a telescopic cylinder, and when blowing is needed, the blowing mechanism 340 is pushed to the bottom end of the clamping member 330 by the cylinder. When tearing the film, the telescopic cylinder pulls the blowing mechanism 340 back, so as to avoid the film tearing and clamping mechanism 320. When the film tearing device 300 is arranged at the bottom end of the conveying line 200, the blowing mechanism 340 is arranged at the top end of the clamping member 330, so that the label adhered to the end of the glass can be blown downwards to the clamping member 330, so that the clamping member can clamp the free end of the label. Further, when the blowing device is arranged at the top side and the bottom side of the conveying line 200, the blowing mechanism 340 connected to the bottom side blows upwards to blow the label on the top surface of the glass to the clamping member 330 at the top side, and the blowing mechanism 340 at the top side blows downwards to blow the label on the bottom of the glass to the clamping member 330 at the bottom side.

[0033] Further, with reference to Figure 4 and Figure 6 The clamping member 330 comprises a lifting assembly 331, a fixed clamping plate 332, a cylinder 333 and a clamping block 334. The lifting assembly 331 is connected to the rack 100. The fixed clamping plate 332 is arranged at the lifting end of the lifting assembly 331. One end of the fixed clamping plate 332 is provided with a clamping portion and a connecting portion. The cylinder 333 is arranged at one side of the fixed clamping plate 332. One side of the clamping block 334 is pivotally connected to the connecting portion. The cylinder 333 is arranged at one side of the fixed clamping plate 332, and the telescopic rod of the cylinder 333 is pivotally connected to the clamping block 334. The cylinder 333 pushes the clamping block 334, so that the clamping block 334 is clamped at one side of the clamping portion. Specifically, when the end of the glass with the label is conveyed to the bottom end of the clamping member 330 by the conveying line 200, the clamping block 334 is turned over by the cylinder 333, so that the end of the label is clamped between the clamping portions, and the label is clamped tightly, so that the film tearing device 300 can tear the protective film on the surface of the glass.

[0034] Further, with reference to Figure 6The fixed clamping plate 332 is further provided with a mounting sliding groove, a sliding plate 335 is slidably connected in the mounting sliding groove, the air cylinder 333 is arranged on one side of the sliding plate 335, and a compression spring 336 is further arranged between the top of the sliding plate 335 and the top wall of the mounting sliding groove, and the compression spring 336 extrudes the sliding plate 335 downward. When the air cylinder 333 pushes the clamping block 334 to open, the end of the clamping block 334 is beyond the end of the fixed clamping plate 335. Moreover, the clamping surface of the clamping block 334 is an inclined surface, when the glass collides with the clamping block 334 in the process of glass conveying, the end of the glass collides with the inclined surface of the clamping block 334, so that the clamping block 334 is pushed upward, and under the action of the compression spring 336, the sliding plate 335 is upwardly avoided, so that the clamping block 334 swings upward, thereby avoiding the glass, avoiding damage to the glass, and playing a good protection role on the glass.

[0035] Further, referring to Figures 1-5 The film tearing device 300 further comprises a cross beam 350 and a linear module 360, the label stripping mechanism 310 is fixedly arranged at one end of the cross beam 350, the film tearing clamping mechanism 320 is slidably connected at the other end of the cross beam 350, the linear module 360 is arranged on one side of the cross beam 350 and connected with the film tearing clamping mechanism 320, and is used for driving the film tearing clamping mechanism 320 to translate. In this embodiment, when the clamping piece 330 of the film tearing clamping mechanism 320 clamps the label, the film tearing clamping mechanism 320 and the conveying line 200 are driven to move in opposite directions by the linear module 360, so that the film tearing efficiency is improved. In addition, the film tearing clamping mechanism 320 and the label stripping mechanism 310 are arranged at two ends of the cross beam 350 respectively, so that the film tearing clamping mechanism 320 and the label stripping mechanism 310 can be ensured to be on a straight line, and the position adjustment of the two is facilitated.

[0036] Further, referring to Figures 1-3 The first end 101 of the rack 100 is provided with a first support 110 and a first mounting beam 120, and the second end 102 is provided with a second support 130 and a second mounting beam 140. The first support 110 and the second support 130 are located above the conveying line 200, and the first mounting beam 120 and the second mounting beam 140 are located at the bottom end of the conveying line 200. The top side and the bottom side of the conveying line 200 are both provided with the film tearing device 300. The two ends of the cross beam 350 located at the top end of the conveying line 200 are respectively overlapped on the first support 110 and the second support 130. The two ends of the cross beam 350 located at the bottom end of the conveying line 200 are respectively overlapped on the first mounting beam 120 and the second mounting beam 140. In this embodiment, the protective films on the upper and lower surfaces of the glass can be simultaneously torn off, and the film tearing efficiency is improved.

[0037] Further, referring to Figures 1-3The top end of the rack 100 is further provided with a partition 150, and the partition 150 is located between the cross beam 350 and the conveying line 200. The bottom end of the conveying line 200 is further provided with a collecting frame 160. In the embodiment, when the film tearing clamping mechanism 320 clamps the protective film, the film tearing clamping mechanism 320 is driven by the linear module 360 to move together, so that the torn protective film can be placed in the partition 150 or the collecting frame 160 for collection, and the torn protective film does not affect the tearing of the next protective film.

[0038] Further, the top end and the bottom end of the conveying line 200 are both provided with two groups of the film tearing device 300, and the film tearing device 300 at the bottom end is arranged in a staggered manner with the film tearing device 300 at the top end. The two groups of film tearing devices 300 arranged above and below can balance the glass during film tearing, and avoid the problem of pulling the glass out of position during film tearing. The film tearing devices arranged above and below are staggered, which can avoid the interference between the label stripping mechanisms 310.

[0039] Further, referring to Figure 2 The two cross beams 340 located on the same side are further provided with an adjusting mechanism 370 for adjusting the distance between the two cross beams 340. Therefore, the film tearing can adapt to the glass of different sizes. The adjusting mechanism 370 is an electric belt mechanism.
