The conveying assembly 11 may be a common conveying belt or a rotating disc in the market, and the structure of the conveying assembly is not limited, so that the function of conveying the product adhered with the transparent adhesive film 10 to the lower part of the film pressing device 23 can be realized.

When the film needs to be fed, the rolling device rotates to drive the material belt to move, so that the transparent adhesive film 10 on the material belt passes through the guide groove and reaches the position of the stripping knife 13, because the knife edge of the stripping knife 13 is in an acute angle shape, when the transparent adhesive film 10 passes through the stripping knife 13, one end of the transparent adhesive film 10 is stripped from the material belt by the stripping knife 13 after passing through the stripping knife 13, then the material taking and placing device 22 is waited to completely strip the transparent adhesive film 10 from the material belt, in the process of completely stripping the transparent adhesive film 10 from the material belt, the pressing device presses the material belt tightly to ensure that the material belt does not deviate in the complete stripping process, after the transparent adhesive film 10 is stripped, the pressing device loosens the material belt, then the rolling device rotates to drive the material belt to continue to move until the next transparent adhesive film 10 passes through the stripping knife 13, the film feeding process is completed, and the rate of tearing the transparent adhesive film 10 from, the working efficiency is high.

When the film is required to be pasted, the transparent adhesive film 10 which is half-peeled from the material belt by the peeling knife 13 is sucked up by the negative pressure of the material sucking component in the material taking and placing device 22, then the swinging driving component 223 works to drive the swinging platform 222 to rotate on the swinging base 221 until the transparent adhesive film 10 of the material sucking component rotates to the upper side of the product, then the material sucking component stably places the transparent adhesive film 10 on the product to complete the film pasting process, and then the swinging driving component 223 works to enable the material sucking component to return to the original position.

As shown in fig. 1 to 9, in the film sticking apparatus according to the embodiment, the guide grooves include a first guide groove 1211 and a second guide groove 1212; the rod guide assembly comprises a fixed table 122, a sliding table 123, a fixed table 122, a sliding table 123 and a distance adjusting part for controlling the distance between the sliding table 123 and the fixed table 122; the fixed table 122 is arranged side by side with the sliding table 123; the first guide groove 1211 is disposed on the top surface of the fixing table 122; the second guide groove 1212 is disposed on the top surface of the sliding table 123; the fixed table 122 is fixedly arranged on the machine table 17; the sliding table 123 is mounted on the machine table 17 through the distance adjusting member; the fixed table 122 and the sliding table 123 are sequentially arranged in the moving direction of the material belt; the stripping knife 13 is mounted at the discharge end of the second guide groove 1212;

specifically, the guide grooves are respectively arranged on the top surface of the fixed table 122 and the top surface of the sliding table 123, and the material belt passes through the guide groove on the top surface of the fixed table 122 and the guide groove on the top surface of the sliding table 123 in sequence, and then reaches the stripping knife 13 at the discharge end of the guide groove to perform the stripping process. In operation, one end of the transparent adhesive film 10 on the material belt passes through the stripping knife 13 and is stripped from the material belt by the stripping knife 13, and then the material taking and placing device 22 waits for the transparent adhesive film 10 to be completely stripped from the material belt. In order to adapt to the machine tables 17 with different sizes, match the operating distance of workers and match the material taking and placing devices 22 with different sizes, the distance adjusting component is added, so that the sliding table 123 can move forwards or backwards relative to the machine tables 17, the distance between the devices is adjusted, and the universality is high.

As shown in fig. 2, 3 and 5, in the film laminating apparatus of the present embodiment, the distance adjusting component includes a transverse rail 124 disposed on the machine table 17, a transverse slider 125 slidably connected to the transverse rail 124, and an adjusting cylinder 126 for making the transverse slider 125 slide on the transverse rail 124; the sliding table 123 is arranged on the top of the transverse sliding block 125; the adjusting cylinder 126 is installed on the machine table 17.

Specifically, when the position of the sliding table 123 needs to be adjusted, the output end of the adjusting cylinder 126 only needs to be correspondingly extended or retracted, so as to drive the transverse sliding block 125 to slide on the transverse rail 124. Since the sliding table 123 is disposed on the top of the lateral slider 125, the sliding table 123 can move away from or close to the fixed table 122, thereby adjusting the position of the sliding table 123.

specifically, when the pick-and-place device 22 is to completely peel the transparent adhesive film 10 from the tape, it is necessary to ensure that the tape is compressed and does not move with the peeling operation. Otherwise, the whole material strip is loosened, and the next material stripping process of the transparent adhesive film 10 is affected; it may even happen that the transparent adhesive film 10 cannot be peeled off from the tape due to the movement of the tape. Therefore, it is necessary to prevent the tape from shifting during the peeling process. When the material pressing device works, the first material pressing cylinder 142 drives the material pressing block 141 to descend towards the direction of the guide groove until the material pressing block 141 presses the material belt; when the material belt needs to be moved continuously, the first pressing cylinder 142 drives the pressing block 141 to ascend until the pressing block 141 leaves the material belt. Specifically, a plurality of special-shaped transparent adhesive films 10 are provided with holes, and the positioning protrusions 144 and the positioning holes 145 are matched in shape with the holes, so as to further compress the material belt and improve the positioning accuracy.

As shown in fig. 5, in the film laminating apparatus according to the embodiment, the second pressing part 15 includes a knurling shaft 151, a pressing shaft 152, and a second pressing cylinder 153 for controlling the distance between the pressing shaft 152 and the knurling shaft 151; the knurled shaft 151 is mounted to the rod guide assembly; the pressing shaft 152 is connected to the rod guide assembly through the second material pressing cylinder 153.

In particular, in order to further ensure that the strip of material does not drift, it is necessary to provide a second pressing member 15 at the bottom of the stripping knife 13 that presses the strip of material. During operation, the second pressing cylinder 153 drives the pressing shaft 152 to descend toward the knurling shaft 151 until the pressing shaft 152 presses the material tape; when it is desired to continue moving the strip of material, the second nip cylinder 153 drives the nip shaft 152 away from the knurling shaft 151 until the nip shaft 152 is clear of the strip of material.

As shown in fig. 2-3, the film pasting apparatus of the present embodiment comprises a feeding base 131, a material tape roll mounting member for mounting a material tape roll, and at least one feeding guide roller 132; the coil mounting member and the feed guide roller 132 are both mounted on the feed base 131; the web roll mounting means comprises an unwinding roller 133, a first torque adjuster and at least two fastening tabs 135; one end of each fastening tab 135 is connected to one end of the unwinding roller 133; the fastening tabs 135 are evenly distributed around the circumference of the unwinding roller 133; the other end of the unwinding roller 133 is mounted on the feeding base 131 through the first torque adjuster; as shown in fig. 2, 3 and 4, the winding device includes a winding roller 161, a second torque adjuster 162, a belt transmission member 163 and a winding motor 164 for driving the winding roller 161 to rotate; one end of the wind-up roll 161 is connected with the second torque adjuster 162; the output end of the winding motor 164 is connected to the second torque adjuster 162 through the belt transmission member 163.

Specifically, the first torque regulator is a commercially available torque regulator, and the structure of the torque regulator is not limited, and the torque regulator can adjust the friction between the unwinding roller 133 and the feeding base 131, and can adjust the torque to maintain the material roll at a proper tension. The second torsion adjuster 162 may be a commercially available torsion adjuster, and the structure thereof is not limited, so that it is sufficient to prevent the strip from being broken due to the tightening of the strip after the strip on the wind-up roll 161 is wound to be larger. When the material tape roll is installed, the diameter of the inner ring of the material tape roll is slightly smaller than the diameter of the circumscribed circle formed by the outer side of the fastening piece 135, and as the fastening piece 135 is uniformly distributed around the circumference of the unwinding roller 133, when the material tape roll is installed on the unwinding roller 133, only the material tape roll needs to be pushed with force, and the inner ring of the material tape roll can press the outer side of the fastening piece 135, so that the material tape roll can be relatively fixed on the unwinding roller 133; when the tape roll needs to be dismounted, the tape roll only needs to be pulled out forcefully.

After the film pasting process is completed, in order to ensure that the transparent adhesive film 10 can be smoothly pasted on the product, the film pressing process needs to be performed on the pasted product, so as to ensure that no bubbles or raised angles exist between the transparent adhesive film 10 and the product. The conveying assembly 11 conveys the filmed product to the lower part of the film pressing device 23, and starts the film pressing process. The specific film pressing process comprises the following steps: when the product after the film is pasted reaches the lower part of the film pressing roller 232, the film pressing lifting component drives the film pressing roller 232 to descend to the surface of the product, then, the film pressing translation component drives the film pressing roller 232 to roll back and forth on the surface of the product, and the transparent adhesive film 10 can be smoothly pasted on the product. Specifically, when the squeeze film roller 232 needs to be lifted, the lifting cylinder 264 correspondingly drives the lifting slider 263 to slide along the lifting slide rail 262, so as to drive the squeeze film roller 232 at the bottom of the lifting slider 263 to lift; when the film pressing roller 232 needs to roll on a product pasted with the transparent adhesive film 10, that is, the film pressing roller 232 needs to be translated, the translation cylinder 254 correspondingly drives the translation sliding block 253 to slide along the translation sliding rail 252, so that the film pressing roller 232 at the bottom of the translation sliding block 253 can be driven to translate.
