Description
Technical Field
[0001] The utility model relates to the technical field of OCA optical adhesive processing, and more specifically, to a slicing processing device for OCA optical adhesive production. Background Technique
[0002] OCA optical film is an optical material with high cleanliness and high light transmittance. It is made of optical acrylic adhesive and has a release film laminated on each of the upper and lower bottom layers. This film has multiple advantages, including high light transmittance (total light transmittance > 99%), low haze, high adhesion, water resistance, high temperature resistance, and anti-ultraviolet properties. After the applicant's search, in the production process of OCA optical adhesive, trimming the edge is an important step. The edges of the optical film may have defects such as burrs, irregularities, or excess glue due to process reasons during production. By trimming the edge, these defects can be removed to ensure the overall quality and appearance of the product. At the same time, trimming the edge can ensure that the size and shape of the optical film exactly meet the design requirements and satisfy the specific needs of customers.
[0003] When the existing OCA optical film cutting device trims the edge, due to the fixed design of the cutting table and the cutting table being located below the cutting knife, when placing and cleaning the tabletop, the hand is often located below the cutting knife, resulting in low safety during the processing. Secondly, if the cutting table is designed as a sliding push-pull structure, although the safety is effectively improved, the loading and unloading steps become cumbersome and consume a lot of manpower, and adding an additional electric drive will increase the energy consumption.
[0004] Therefore, in view of the above problems, it is necessary for the applicant to design a slicing processing device for OCA optical adhesive production to solve the problems. Summary of the Utility Model
[0005] The purpose of the utility model is to provide a slicing processing device for OCA optical adhesive production to solve the problems mentioned in the above background technique.

A knife plate is installed on the top of the cutting frame through a cylinder. It is characterized in that two driving strip plates are rotatably connected to one side of the knife plate. The bottom ends of the driving strip plates are rotatably connected to the top of a telescopic rod. The telescopic rod is fixed at a position on one side of the cutting table. The telescopic rod is designed as an elastic telescopic rod. A baffle is installed on the top of the device base on one side of the cutting frame.
[0007] Preferably, two convex-shaped sliding plates are fixed to the bottom of the cutting table. The sliding plates slide in two sliding channels at the top of the equipment base. The bottom of the sliding plates does not contact the inner bottom end of the sliding channels. A row of ball grooves is provided at the bottom of the sliding plates, and balls are provided in the ball grooves and roll at the bottom end of the sliding channels.
[0008] Preferably, the telescopic rod is divided into a sleeve rod and a rod body. The sleeve rod is fixed to the side wall of the cutting table. The rod body slides in a rod hole on one side of the sleeve rod. A first spring is connected between one side of the rod body and the inner wall of the sleeve rod, and the bottom end of the rod body is rotatably connected to the driving strip plate.
[0009] Preferably, two limiting blocks are fixed to the inner wall of the sleeve rod, and the limiting blocks are attached to the telescopic rod.
[0010] Preferably, a cross plate is fixedly connected between the driving strip plates, and a bent second spring is connected between the cross plate and the knife plate.

Detailed implementation manners
[0023] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0024] As Figures 1-6 shown, a slicing processing device for OCA optical adhesive production of the present utility model includes an equipment base 1, a cutting table 3 is slidably connected to the top of the equipment base 1, a cutting frame 2 is fixed to one side of the cutting table 3 at the top of the equipment base 1, a knife plate 5 is installed at the top of the cutting frame 2 through a cylinder 4, two driving strip plates 6 are rotatably connected to one side of the knife plate 5, the bottom ends of the driving strip plates 6 are rotatably connected to the top of a telescopic rod 7, the telescopic rod 7 is fixed at a position on one side of the cutting table 3, the telescopic rod 7 is designed as an elastic telescopic rod 7, and a baffle 8 is installed on the top of the equipment base 1 on one side of the cutting frame 2.
[0025] As described above, by designing the driving strip 6, the telescopic rod 7 and the baffle 8, when cutting the edge of the OCA optical film, the film is placed on the cutting table 3 and attached to the inner surface facing the knife plate 5. Then, the air cylinder 4 is activated to drive the knife plate 5 downward. The driving strip 6 rotates, and its bottom can push the elastic telescopic rod 7 and drive the cutting table 3 to slide. When the bottom end of the knife plate 5 is close to the upper end of one side of the cutting table 3, the baffle 8 contacts the cutting table 3. At this time, the cutting table 3 cannot be displaced. The knife plate 5 continues to descend into the interior of the cutting table 3. At this time, the driving strip 6 will drive the telescopic rod 7 to extend. Then, the knife plate 5 fits with the inner top surface of the cutting table 3 to complete the cutting of the film edge. After that, the knife plate 5 resets, and the cutting table 3 also completes the reset through the driving strip 6 and the telescopic rod 7. At this time, the cutting table 3 is located on one side of the knife plate 5. Then, the film is taken out and sliced on the other side. In this way, it is safer when placing, taking, or cleaning the cutting table 3, and the automatic loading and unloading is more convenient, improving work efficiency.
[0026] Two convex-shaped sliding plates 14 are fixed at the bottom of the cutting table 3. The sliding plates 14 slide in two slideways at the top of the equipment base 1. The bottom of the sliding plates 14 does not contact the inner bottom end of the slideways. A row of ball grooves is provided at the bottom of the sliding plates 14, and balls 15 are provided in the ball grooves. The balls 15 roll at the bottom end of the slideways.
[0027] As described above, through the two convex-shaped sliding plates 14, the cutting table 3 can stably slide linearly on the top of the equipment base 1. The balls 15 replace the bottom surface of the sliding plates 14 to contact the inner bottom end of the slideways. When the cutting table 3 moves, it can roll inside the slideways by itself, thereby reducing the resistance of the cutting table 3 during movement and reducing the burden on the spring 73 to drive the cutting table 3 to move. It is very practical.
[0028] The telescopic rod 7 is divided into a sleeve rod 71 and a rod body 72. The sleeve rod 71 is fixed on the side wall of the cutting table 3. The rod body 72 slides in the rod hole on one side of the sleeve rod 71. A spring 73 is connected between one side of the rod body 72 and the inner wall of the sleeve rod 71, and the rod body 72 is rotatably connected to the bottom end of the driving strip 6.
[0029] As described above, through the design of the telescopic rod 7, when the driving strip 6 rotates under the drive of the downward movement of the knife plate 5, the spring 73 can be used to drive the sleeve rod 71 and the cutting table 3 to move. In this way, after the baffle 8 contacts the cutting table 3 and cannot move, and the knife plate 5 needs to continue to descend for cutting, the telescopic structure composed of the sleeve rod 71 and the rod body 72 is used at this time.
[0030] Two limit blocks 74 are fixed on the inner wall of the sleeve rod 71, and the limit blocks 74 are attached to the rod body 72.
[0031] As described above, during reset, the rod body 72 will be in contact with the limit block 74, and then push the sleeve rod 71 and the cutting table 3 to reset, thus avoiding relying on the first spring 73 to push the cutting table 3 to move and reset during reset, reducing the burden on the first spring 73. It should be noted that when the cutting table 3 is in its initial position, the limit block 74 is in contact with the rod body 72.
[0032] A cross plate 10 is fixedly connected between the driving strip plates 6. A bent second spring 11 is connected between the cross plate 10 and the knife plate 5. Two fitting blocks 12 are fixed on one side of the knife plate 5. A rubber pad 13 is bonded to the inclined surface on one side of the fitting block 12, and the rubber pad 13 is in contact with the driving strip plate 6.
[0033] As described above, after the knife plate 5 is reset, the rubber pad 13 on one side of the fitting block 12 is in contact with the driving strip plate 6, which can provide a supporting effect on the driving strip plate 6. The second spring 11 can be stretched due to the rotation of the driving strip plate 6 when the knife plate 5 descends, thus playing a good buffering role.
[0034] A positioning part 9 is installed at the top of the cutting table 3, including a U-shaped plate 91 fixed at the top of the cutting table 3. A screw rod 92 is threadedly connected to the U-shaped plate 91. The bottom of the screw rod 92 rotates on the top of a pressing plate 93, and two limit slide rods 94 passing through the U-shaped plate 91 are fixed on both sides of the top of the pressing plate 93.
[0035] As described above, by designing the positioning part 9, when cutting and placing the film, the film is passed under the pressing plate 93 and then placed on the top of the cutting table 3. At this time, one end of the film is under the pressing plate 93 and the other end is in contact with the inner wall of the cutting table 3. Then the screw rod 92 is rotated. Under the limitation of the two limit slide rods 94, the pressing plate 93 moves down to press the film, so that the film will not shake during cutting, effectively improving the stability of cutting. It should be noted that the positioning part 9 is designed at the middle position at the top of the cutting table 3.
[0036] Enlightened by the ideal embodiments of the present invention described above, through the above description, relevant staff can make various changes and modifications completely within the scope without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
