Specifically, the sucking assembly 121 includes circular suckers and sponge suckers in the middle, which are disposed at two sides of the product bearing area 112, and a PCB small sucker at the rear, where the circular suckers at two sides are responsible for sucking the side portion of the liquid crystal display panel, and the sponge sucker in the middle is responsible for sucking the middle portion of the liquid crystal display panel; the middle sponge sucker is adopted, which mainly has the functions of increasing the adsorption area and avoiding the interference with the manual sucker group as much as possible (the manual sucker group is a sucker which is practical when a product is adsorbed and placed in the product bearing area 112 through the manual sucker group manually). The lifting assembly 122 is connected to the suction assembly 121 in a transmission manner to drive the lifting of the suction assembly 121. Specifically, drive assembly is the lead screw drive, including the installation piece, the installation piece is connected in the sucking disc subassembly, and installation piece and lead screw threaded connection, the below of mounting bracket 123 is located to the installation piece, the lead screw passes the top and the installation piece threaded connection of mounting bracket 123, the lead screw still is connected with the motor simultaneously, starter motor, the motor drive lead screw is rotatory, it makes the screw motion to drive the installation piece with the lead screw, the length direction up-and-down motion along the lead screw is followed to the installation piece promptly, owing to absorb the subassembly 121 and install in the installation piece, can realize absorbing the lift of subassembly 121 from this.

As shown in fig. 6, in this embodiment, the film tearing mechanism 130 includes: the film tearing roller 131 is slidably arranged on the rack 110, and can reciprocate between the placing area 111 and the product bearing area 112 to tear off the protective film on the lower surface of the product;

the static eliminating rod 132 is slidably disposed on the frame 110, and can reciprocate between the placing region 111 and the product bearing region 112, and the static eliminating rod 132 is located behind the film tearing roller 131 to eliminate static electricity generated to the product after the film tearing roller 131 tears off the protective film.

The film tearing mechanism 130 and the film lifting mechanism 140 work together to completely tear off the protective film. The film tearing mechanism 130 includes a film tearing roller 131 and an electrostatic eliminating rod 132, and both the film tearing roller 131 and the electrostatic eliminating rod 132 are slidably disposed on the frame 110 and can reciprocate between the placement region 111 and the product bearing region 112 to tear the protective film on the lower surface of the product and eliminate the static electricity of the product. Specifically, the film tearing apparatus further comprises two linear modules 133 for driving the film tearing roller 131 and the static eliminating bar 132 to slide. Two straight line modules 133 set up relatively, and locate the both sides of frame 110 respectively, two straight line modules 133 all extend the setting along the length direction of frame 110 (the farthest length direction of installing district 111 to product bearing area 112), dyestripping roller 131 and electrostatic elimination stick 132 all erect on two straight line modules 133 through two sliders, two sliders are installed respectively in straight line module 133, and can follow the length direction reciprocating motion of straight line module 133, the both ends of dyestripping roller 131 and electrostatic elimination stick 132 are connected respectively in two sliders, and electrostatic elimination stick 132 locates behind dyestripping roller 131. That is, the film tearing roll 131 and the static electricity eliminating bar 132 can reciprocate along the length direction of the linear module 133.

The film tearing roller 131 is used for contacting with the protective film, that is, when the film tearing mechanism 140 tears a part of the protective film, the film tearing mechanism 140 moves downwards to strain the protective film, and simultaneously the remaining part of the protective film can be torn off by the horizontal movement of the film tearing roller 131, so that the length setting of the horizontal driving assembly 143 in the film tearing mechanism 140 can be reduced, that is, the space occupation of the film tearing mechanism 140 is reduced. When the film tearing roller 131 pushes the protective film to separate from the liquid crystal display panel, the static electricity eliminating rod 132 can eliminate the static electricity on the liquid crystal display panel so as to avoid the influence of the static electricity generated after the protective film is separated from the liquid crystal display panel, so that the problem of occupied space of the film tearing equipment can be solved through the arrangement of the horizontal film lifting mechanism 140, and the production cost is reduced.

In this embodiment, the film tearing device further includes a positioning platform 150, and the positioning platform 150 is disposed in the product carrying area 112, movably connected to a side edge of the rack 110, and capable of opening or covering the product carrying area 112.

The positioning platform 150 is used for carrying the liquid crystal display panel, the liquid crystal display panel is manually placed on the positioning platform 150 before film tearing, and the liquid crystal display panel is transferred from the positioning platform 150 to a film tearing position through the transfer mechanism 120. Specifically, the positioning platform 150 is connected to the frame 110 via a hinge, and when the positioning platform 150 carries the liquid crystal display panel, at least a part of the opening is covered, and a part of the opening is used for the film raising mechanism 140 to lift, that is, the positioning platform 150 is arranged to be away from the film raising mechanism 140. When the protection film on the lcd panel is torn by the film tearing mechanism 140, the positioning platform 150 is turned over into the frame 110, i.e. the opening is opened, so that the torn protection film falls into the frame 110 and the lcd panel is taken away. The positioning platform 150 of the present embodiment can ensure the stability of the lcd panel when the lcd panel is placed in the frame 110.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
