DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] Please refer to Figure 1-10 ;

[0036] The protective film stripping machine of the present invention performs automatic stripping for the film-sticking method in which the protective film area is larger than the plate area, thereby improving production efficiency; the plate mentioned in the present invention has only one-side film sticking, that is, it only needs to strip the protective film on one side, and in addition, the protective film not only completely covers one side of the plate, but also partially extends outside the plate; preferably, the length of the protective film extending outside the plate is greater than 20 mm, and the protective film is a sticky blank release paper. The device specifically includes a panel 1, a feeding mechanism 2, a film pressing mechanism 3 and a film tearing mechanism 4;

[0037] In the initial state, the film pressing mechanism 3 and the panel 1 are offset, and then the product is transferred to the panel 1 through the feeding mechanism 2. At this time, the protective film protrudes from the edge of the panel 1. Then the film pressing mechanism 3 moves from top to bottom or from bottom to top, close to the edge of the panel 1, and at the same time, the protective film protruding from the edge of the panel 1 is picked up, so that the protective film is facing downward or upward, and the bending direction of the protective film corresponds to the film tearing mechanism 4. At the same time, the film tearing mechanism 4 will clamp the position of the edge of the protective film, and the film tearing mechanism 4 will pull the protective film backward. Under the action of the friction between the protective film and the plate, the plate is pushed toward the end face direction of the film pressing mechanism 3 while the protective film is peeled off from the plate.

[0038] The film tearing mechanism 4 in the present invention has two installation methods;

[0039] Embodiment 1, refer to Figure 1 The film-tearing mechanism 4 is installed on the top. At this time, the protective film is located on the upper surface of the plate. A limit piece is provided near the edge of the panel 1. A stopper is formed between the limit piece and the panel 1 to limit the plate from jumping. In the initial state, the end face of the film-pressing mechanism 3 is misaligned with the panel 1 or flush with the panel 1. During operation, the plate is fed into the stopper between the limit rod and the panel 1 through the feeding mechanism 2. At this time, the protective film protrudes from the edge of the panel 1 and the limit piece. Then the film-pressing mechanism 3 is lifted upward and the protective film is bent upward. At the same time, the film-tearing mechanism 4 clamps the edge of the protective film bent upward, and the film-pressing mechanism 3 is reset and moves downward so that its end face is flush with the panel 1. Then the film-tearing mechanism 4 pulls the protective film upward. Under the restriction of the stopper, the plate will not jump. At the same time, under the friction between the plate and the protective film, the plate is translated toward the end face of the film-pressing mechanism 3. When the protective film is completely peeled off from the plate, the plate is also completely moved out of the stopper. At this time, the plate can be transferred to the next step of the process.

[0040] Example 2, refer to Figure 2-4 The feeding mechanism is installed above the panel 1, and the film tearing mechanism 4 is installed below. At this time, the protective film is located on the lower surface of the plate. In the initial state, the end surface of the film pressing mechanism 3 is offset and located above the panel 1. When working, the plate is placed on the panel 1 through the feeding mechanism 2, so that the protective film protrudes from the edge of the panel 1.

[0041] Afterwards, the end surface of the film pressing mechanism 3 moves downward to be flush with the panel 1, and at the same time, the protective film is pushed to bend downward. At the same time, the film tearing mechanism 4 clamps the edge of the downward bent protective film, and then the film tearing mechanism 4 pulls the protective film downward. Under the resistance of the panel 1 and the end surface of the film pressing mechanism 3, the plate will not jump. At the same time, under the action of the friction between the plate and the protective film, the plate is translated toward the end surface of the film pressing mechanism 3. After the protective film is completely peeled off from the plate, the plate is placed on the end surface of the film pressing mechanism 3, and the plate can be transferred to the next step of the process.

[0042] Of course, a flexible material, such as felt, can be provided at the end surface of the film pressing mechanism 3 to reduce friction and avoid scratches after the plate enters the end surface of the film pressing mechanism 3.

[0043] The present invention guides the protruding part of the protective film to the film tearing mechanism 4 through the film pressing mechanism 3, and the film tearing mechanism 4 clamps the protective film and performs a peeling operation, while pushing the plate forward to facilitate unloading, and can realize automatic film tearing operation to improve work efficiency;

[0044] In addition, for plates with larger areas, it is difficult to peel off the protective film manually, but the device of the present invention can easily peel off the protective film and reduce the risk of scratching the plate.

[0045] The above embodiment is further expanded on the panel 1. In this embodiment, the panel 1 has a heating function, and the panel 1 has a certain length, for example, the panel 1 has a length greater than that of three plates put together; at the same time, three positions for placing plates are formed, and a plate is sequentially fed into these three positions by the feeding mechanism 2. Each time it enters a position, it will stay for a short time for heating. When the first plate enters the second position, the feeding mechanism 2 will feed the second plate into the first position. When the first plate enters the third position, the feeding mechanism 2 will feed the second plate into the second position, and the third plate into the first position. At this time, the first plate near the edge position of the panel 1 is subjected to a film tearing operation. After the film tearing operation, the third position will be vacant, and the second plate will be fed into the third position, the third plate will enter the second position, and the fourth plate will enter the first position. This cycle is repeated. The stop time of the equipment is reduced by a step-by-step feeding method, and the plate is heated at the same time, so that the adhesion of the protective film to the plate is weakened, making the film tearing operation smoother.

[0046] The present invention also includes a storage mechanism 5 corresponding to the feeding mechanism 2, referring to Figure 5 , wherein the material storage mechanism 5 includes a material storage bin 51, a lifting plate 52 is provided in the material storage bin 51, the lifting plate 52 is connected to the lifting component 1, and the lifting plate 52 is pushed up by the lifting component 1, thereby pushing the stacked plates upward, so as to facilitate the feeding mechanism 2 to take the materials;

[0047] More specifically, the lifting component 1 includes a strip plate 531 installed at the bottom of the storage bin 51, on which a drive motor 3 532 and a screw pair 2 533 with transmission connections are respectively installed, and a slide 534 is installed at the movable end of the screw pair 2 533, and the slide 534 is connected to the strip plate 531 through a sliding pair 535, and a push rod 536 is installed on the slide 534, and the push rod 536 is connected to the lower end surface of the lifting plate 52.

[0048] One embodiment of the feeding mechanism 2 of the present invention is shown in FIG. Figure 6 , specifically including a frame 28, a driving motor 21 is installed at the position of the frame 28, the output end of the driving motor 21 is connected to a transmission rod 23 through a synchronous wheel set 22, the transmission rod 23 is horizontally arranged to penetrate the frame 28 and is rotatably connected, the ends of the transmission rod 23 are respectively connected to synchronous wheel sets 24, two pairs of synchronous wheel sets are installed on the frame 28, the two pairs of synchronous wheel sets 24 are respectively connected to the two ends of the gantry 25, and the two ends of the gantry 25 are slidably connected to the frame 28, the driving motor 21 drives the transmission rod 23 to rotate through the synchronous wheel set 22, and synchronously transmits to the synchronous wheel set 24, and drives through the synchronous wheel set The gantry 25 moves repeatedly; a lifting assembly 26 is installed on the gantry 25. In this embodiment, the lifting assembly 26 can be a cylinder. The output end of the lifting assembly 26 is connected to an "H"-shaped adsorption assembly 27. In this embodiment, the "H"-shaped adsorption assembly 27 spans the storage mechanism 5 and the panel 1. When the length of the panel 1 can only accommodate two plates, that is, the panel 1 has two placement positions, one of which is placed close to the edge of the panel 1, the feeding mechanism 2 only needs to move once to complete the placement of the plate from the storage mechanism 5 on the panel 1, and the transfer of the plate from the first position to the second position close to the edge of the panel 1;

[0049] Furthermore, the adsorption component 27 is in an "H" shape, and the output end of the lifting component 26 is connected to the middle thereof. Within the moving stroke of the feeding mechanism 2, the adsorption component 27 covers the film pressing mechanism 3. When the feeding mechanism 2 reaches the maximum moving stroke, one end of the adsorption component 27 exceeds the range of the end face of the film pressing mechanism 3, that is, the feeding mechanism 2 has a step-by-step loading function and can also be used as a unloading device, thereby simplifying the overall structure of the equipment.

[0050] One embodiment of the present invention regarding the film pressing mechanism 3 is shown in FIG. Figure 7, specifically including a support frame 31, on which a lifting component three 32 is installed. In this embodiment, the lifting component three 32 can be a cylinder, and the output end of the lifting component three 32 is connected to a movable frame 33, and the movable frame 33 is connected to a pressure plate 34, which can be flush with the panel 1. The movable frame 33 is driven up and down by the lifting component three 32, that is, the pressure plate 34 is driven to achieve flushness and offset with the panel 1.

[0051] Furthermore, a plurality of adsorption holes 35 are provided on the pressing plate 34. When the plate moves to the end surface of the pressing plate 34, the adsorption holes 35 generate negative pressure to adsorb the plate, thereby preventing the plate from jumping.

[0052] Furthermore, it also includes a crossbeam 36, which is located above the panel 1. The crossbeam 36 can move up and down. When the film tearing operation is required, the crossbeam 36 moves downward to get close to the panel 1, but does not press the plate, forming a limiting channel to prevent the plate from jumping during the film tearing operation. The two sides of the crossbeam 36 are slidably connected to the film pressing mechanism 3, and are connected to the lifting component four (not shown), and the crossbeam 36 is driven to move up and down through the lifting component four.

[0053] One embodiment of the film tearing mechanism 4 of the present invention is shown in FIG. Figure 8-Figure 10 , specifically including an inclined fixed plate 41. It should be noted that the film tearing mechanism 4 adopts an inclined movement mode, so the end face of the panel 1 can be set to an inclined surface in the same direction as the inclined movement mode; a driving motor 2 42 is installed at the bottom of the fixed plate 41, and the driving motor 2 42 is connected to a screw pair 1 43. The screw pair 1 43 is arranged along the inclined direction of the fixed part, and the screw pair 2 533 is drivingly connected to a mounting plate 44. A cylinder 1 45 is horizontally installed on the mounting plate 44, and a chuck 1 46 is installed at the output end of the cylinder 1 45. The chuck 1 46 is used in conjunction with a chuck 2 47. The chuck 2 47 is connected to the mounting plate 44 and is slidably connected to the fixed plate 41;

[0054] Under the cooperation of the driving motor 21 and the screw pair 43, the mounting part is driven to reciprocate along the inclined direction of the fixed plate 41, and the components for clamping the protective film are all installed on the mounting plate 44, that is, the movement direction of film tearing is formed. In the initial state, the cylinder 45 is in an extended state, at this time, the chuck 1 46 and the chuck 2 47 are in a separated state, and under the action of the film pressing mechanism 3, the edge of the protective film is bent and then directed toward the direction of the chuck 1 46 and the chuck 2 47, and then, driven by the driving motor 21 and the screw pair 43, the various components on the mounting plate 44 are raised as a whole, and finally the edge of the protective film is placed between the chuck 1 46 and the chuck 2 47, at this time, the cylinder 45 contracts, driving the chuck 1 46 to approach the direction of the chuck 2 47, and finally clamping the edge of the protective film, and then, driven by the driving motor 21 and the screw pair 43, the protective film is pulled to move in the inclined direction, so that the protective film is separated from the plate, and at the same time the plate moves toward the end face direction of the film pressing mechanism 3.

[0055] Preferably, mutually meshing teeth 48 are provided on opposite sides of chuck 1 46 and chuck 2 47, so that the edge of the protective film can be bitten and fixed. In addition, a plurality of adsorption holes 49 are provided at the position of chuck 2 47 at the teeth 48 to generate negative pressure to adsorb and fix the protective film to avoid slipping.
