DETAILED DESCRIPTION

[0031] The application relates to a rotating film manufacturing device, improves the film manufacturing efficiency of a traditional device, and saves the manufacturing cost of the device, and is explained in detail in the embodiments.

[0032] Embodiment one: as Figure 1As shown, the rotary film-forming apparatus includes: a rotary adsorption unit 100, a cutting unit 200, and a lifting unit 300; the rotary adsorption unit 100 is used to continuously rotate and transport the adhesive film to various workstations; the cutting unit 200 is installed on one side of the rotary adsorption unit to cut the adhesive film rotated and transported by the rotary adsorption unit 200. The rotary adsorption unit 100 is installed at the output end of the lifting unit 300 to perform lifting and lowering actions on the rotary adsorption unit 100, thereby completing the unloading of the adhesive film.

[0033] like Figure 2 As shown, the rotary adsorption unit 100 includes a side plate 101, a roller 102, a roller seat 103, an air slip ring 104, a connector 105, a fixing member 106, an adsorption plate 107, and a rotary power device. A rotating hole is provided on the lower part of the side plate 101. One end of the roller 102 passes through the rotating hole and is fixedly mounted on the side plate 101 via the roller seat 103. The roller 102 has four independent sealed pipeline channels inside, and a connector is installed at the input end of each of the four sealed pipeline channels. An air slip ring 104 is located near the input end of each sealed pipeline channel. It should be noted that the air slip ring 104 is a precision mechanical component used to transfer gas media between the rotating equipment and a fixed gas source. Its core function is to achieve gas transfer during the equipment's rotation. The continuous and leak-free transmission of the air body solves the problem of the inability to continuously supply air during rotation in traditional rigid pipe connections. The fixed end of the air slip ring 104 is installed on the fixing member 106, which is installed on the side plate 101 through a profile and ensures that the rotation center of the air slip ring 104 is consistent with the rotation center of the roller 102. The rotating end of the air slip ring 104 is connected to the roller 102 through the connector 105. The rotating end of the air slip ring 104 has four connectors, which are connected to the connectors at the input ends of four sealed pipeline channels through air pipes. By opening four independent sealed pipeline channels on the roller 102, the adsorption force of any pipeline channel can be controlled individually. The air slip ring 104 can prevent the air pipe from getting tangled when the roller 102 rotates.

[0034] like Figure 3As shown, a plurality of mounting grooves 108 are formed on the other end of the rotating surface of the roller 102, and each mounting groove 108 is provided with a mounting plate 109 and a support column 110. The adsorption plate 107 is provided with four groups of mounting plates 107 which are evenly arranged around the roller 102 through the support columns 110 in the mounting grooves 108. Each group of adsorption plates 107 includes an adsorption bottom plate 111 and a plurality of adsorption platforms 112. It should be noted that the number of adsorption platforms 112 is determined according to the number of sections of the adhesive film to be cut at one time. When the adhesive film needs to be cut into several parts, a corresponding number of adsorption platforms are needed. In this embodiment, the adhesive film needs to be cut into two ends at one time, so two adsorption platforms 112 are provided, and the two adsorption platforms 112 are symmetrically arranged on the adsorption bottom plate 111. A plurality of adsorption holes are arranged on each adsorption platform 112. An adsorption cavity is formed on the adsorption bottom plate 111, and the adsorption hole and the adsorption cavity are connected. The adsorption cavity formed on each adsorption plate 107 is connected with the output end of four independent sealing pipeline channels formed on the roller 102 through a gas pipe. The setting of the adsorption plate 107 can adsorb the adhesive film, and the plurality of adsorption holes can further increase the adsorption force.

[0035] A rotating power device is arranged above the roller 102, which includes a power source, a synchronous belt 113 and a synchronous pulley 114. In this embodiment, the power source is an electric motor 115, a speed reducer 116 and a connecting seat 117. The output end of the electric motor 115 is connected with the input end of the speed reducer 116, and the speed reducer 116 is fixedly installed on the upper position of the side plate 101 through the connecting seat 117. It should be noted that the motor is an execution element of a closed-loop control system, which converts electrical signals into precise mechanical movements by receiving control signals, and realizes high-precision control of position, speed and torque. The speed reducer is a mechanical transmission device which converts the high speed of the power source (such as the motor) into low speed and increases the output torque at the same time to meet the specific requirements of the equipment on speed and torque. Its core function is "speed reduction and torque increase", and it is widely used in mechanical systems that need power matching. The synchronous pulley 114 is provided with two groups which are respectively installed on the output end of the speed reducer 116 and the roller 102 below the corresponding position, and the two groups of synchronous pulleys 114 are connected through the synchronous belt 113. It should be noted that the synchronous pulley and the synchronous belt are a transmission combination based on the principle of tooth shape meshing, which realizes non-slip power transmission and motion control through the precise matching of the teeth on the synchronous belt and the tooth groove of the synchronous pulley. The two need to be used together and are widely used in mechanical systems that need high precision and stable transmission ratio. When the power source drives the synchronous pulley 114 to rotate, the roller 102 on which the adsorption plate 107 is installed below is driven to rotate. The setting of the rotating power device can drive the adsorption plate 107 to rotate, and then realize the rotation of the adsorption plate 107 for adsorbing and carrying the adhesive film.

[0036] AsFigure 4 As shown in the drawings, in order to ensure the precision of the adhesive film carrying by the adsorption plate 107, the rotary adsorption unit 100 further comprises an auxiliary rotating mechanism, which comprises a fixed assembly and an auxiliary rotating assembly.

[0037] As shown in the drawings, Figure 5 The fixed assembly is arranged at both ends of the adsorption plate 107, which comprises a first fixed plate 118, a second fixed plate 119 and a fixed column 120. The first fixed plate 118 and the second fixed plate 119 are installed on the side plate 101 through the fixed column 120 with different lengths and are located at both ends of each group of adsorption plates 107. The first fixed plate 118 and the second fixed plate 119 are both provided with an annular groove 121 on the side opposite to the adsorption plate 107.

[0038] As shown in the drawings, Figure 6 The auxiliary rotating assembly is installed on the adsorption plate 107, which comprises a fixed block 122 and a bearing 123. The bearing 123 is installed at the bottom of the adsorption bottom plate 111 by sleeving the fixed block 122. The auxiliary rotating assembly is installed at the center position of both ends of each adsorption plate 107. The bearing 123 in the auxiliary rotating assembly abuts against the annular groove 121 in the first fixed plate 118 and the second fixed plate 119. Through the setting of the auxiliary rotating mechanism, the rotation of the drum 102 driving the adsorption plate 107 is more stable, thereby ensuring the precision of the adhesive film carrying by the adsorption plate 107.

[0039] As shown in the drawings, Figure 7 It should be noted that the rotary adsorption unit 100 is provided with positions with different functions, which include a feeding position X, a cutting position Y and a discharging position Z. The feeding position X is located above the rotary adsorption unit 100, the cutting position Y is located on one side of the rotary adsorption unit 100, and the discharging position Z is located below the rotary adsorption unit 100. The rotary adsorption unit 100 rotates and carries the adhesive film from the feeding position X to the cutting position Y and the discharging position Z in sequence for processing. Through the setting of the rotary adsorption unit 100, the multiple groups of adsorption plates 107 can continuously feed, cut and discharge the adhesive film, reducing the carrying mechanism required for carrying the adhesive film to each station in the traditional film preparation device, saving the manufacturing cost of the equipment and improving the preparation efficiency of the adhesive film.

[0040] In this embodiment, the preparation process of the adhesive film requires that the adhesive film is pulled out from the adhesive film roll and cut into two adhesive films of the same size at one time. Therefore, the rotary film preparation device comprises a cutting unit 200, which is located at the cutting position Y of the rotary adsorption unit 100 and comprises a cutting assembly, a horizontal moving force device and an avoiding power device. The cutting assembly is installed at the output end of the horizontal moving force device, the fixed end of the horizontal moving force device is installed at the output end of the avoiding power device, and the avoiding power device is installed on the side plate 101.

[0041] AsFigure 8 As shown, the cutting assembly includes a connecting plate 201, a telescopic power device, a first cutting knife 202, and a second cutting knife 203. In this embodiment, the telescopic power device is a slide table cylinder 204. It should be noted that the slide table cylinder is a pneumatic actuator that integrates the linear reciprocating motion of the cylinder and the precision guide mechanism (such as guide rail and sliding block) into one body. It is driven by compressed air to move the piston, which drives the slide table to achieve high-precision and stable linear motion, and is widely used in automation equipment, precision positioning, material handling, and other scenes. The first cutting knife 202 is obliquely arranged at the top end of the connecting plate 201 through the telescopic power device, and the second cutting knife 203 is installed at the bottom end of the connecting plate 201. The first cutting knife 202 performs the actions of feeding and retracting through the telescopic power device to cut the film in the first cutting gap. The second cutting knife 203 is used to cut the film in the second cutting gap. In this embodiment, the first cutting gap is the gap between the adsorption plate 107 at the feeding position X and the adsorption plate 107 at the cutting position Y, and the second cutting gap is the gap between the two groups of adsorption platforms 112 on the adsorption plate 107 at the cutting position Y. Through the arrangement of the cutting assembly, the film at the cutting position Y of the rotary adsorption unit 100 can be cut.

[0042] As shown in Figure 9 The cutting assembly is installed at the output end of the horizontal power device. The horizontal power device includes a driving mechanism, a horizontal fixed plate 205, a shaft 206, a b synchronous belt 207, a synchronous driving wheel 208, a synchronous driven wheel 209, and a belt fixing block 211. In this embodiment, the driving mechanism is a b motor 210, which is fixedly installed at one end of the horizontal fixed plate 205. The shaft 206 is provided with two groups of shafts arranged at the two ends of the horizontal fixed plate 205. One of the shafts 206 is connected to the output end of the b motor 210 through a shaft coupling. The synchronous driving wheel 208 is fixedly installed on the shaft 206 at the output end of the b motor 210. In order to ensure the rotation accuracy of the synchronous driving wheel 208, the shaft 206 is fixedly installed in the bearing of the horizontal fixed plate 205. The synchronous driven wheel 209 is installed at the other end of the horizontal fixed plate 205 through another shaft 206. The synchronous driven wheel 209 is connected to the synchronous driving wheel 208 through the b synchronous belt 207. The horizontal fixed plate 205 is provided with sliding rails and sliding blocks at the top and bottom ends. The cutting assembly is fixedly installed on the two groups of sliding blocks through the connecting plate 201. The connecting plate 201 is fixedly connected to the b synchronous belt 207 through the belt fixing block 211. When the driving mechanism drives the synchronous driving wheel 208 to rotate, the cutting assembly connected to the b synchronous belt 207 is driven to move horizontally and cut.

[0043] As shown in Figure 10As shown, the horizontal moving force device is installed at the output end of the avoiding power device, and the avoiding power device comprises a power mechanism and a fixing block 212. In this embodiment, the power mechanism is a slide rail, a slide block and an a finger air cylinder 213. The slide rail is horizontally installed on the side plate 101, the slide block is slidably connected with the slide rail, and the a finger air cylinder 213 is installed between the two slide rails through the fixing block 212. The horizontal moving force device is installed on the slide block through a horizontal moving fixing plate 205, and the output end of the a finger air cylinder 213 is connected with the horizontal moving fixing plate 205. When the a finger air cylinder 213 performs the extension and retraction action, the horizontal moving force device can be driven to move relative to the side plate 101 in cooperation with the slide rail and the slide block. The cutting unit can be driven to move horizontally by the avoiding power device, so as to prevent the cutting unit from interfering with the rotating and carrying path of the rotating adsorption unit 100.

[0044] As shown, Figure 11 When the cutting assembly cuts the adhesive film, the adhesive film will be in hard contact with the cutting assembly, which will cause the adhesive film to slip during cutting, thereby affecting the preparation accuracy of the adhesive film. The adsorption force of the rotating adsorption unit 100 is far from enough to cooperate with the cutting assembly for cutting. Therefore, the cutting unit 200 further comprises a pressing mechanism. The pressing mechanism further comprises a feeding position pressing assembly and a cutting position pressing assembly. The feeding position pressing assembly is used to act on the adhesive film at the first cutting gap position in cooperation with the cutting position pressing assembly. The cutting position pressing assembly simultaneously acts on the adhesive film at the first and second cutting gap positions.

[0045] As shown, Figure 12 The feeding position pressing assembly specifically comprises a pressing support 214, a b finger air cylinder 215, a mounting piece 216, a lifting shaft 217, a horizontal hanging plate 218, a first pressing plate 219 and a buffer block 220. In this embodiment, the buffer block 220 is made of rubber material. The pressing support 214 is installed on the side plate 101 and located at the feeding position X of the rotating adsorption unit 100. The pressing support 214 is further provided with a mounting hole and a guide hole. The b finger air cylinder 215 is installed in the mounting hole of the pressing support 214 through the mounting piece 216. The lifting shaft 217 is provided with two groups of guide holes installed on the two sides of the mounting hole, respectively. The horizontal hanging plate 218 is fixedly connected with the output end of the b finger air cylinder 215 and the lifting shaft 217. The first pressing plate 219 is installed on the horizontal hanging plate 218 through the buffer block 220. When the b finger air cylinder 215 operates, the first pressing plate 219 can be driven to perform the lifting action, so as to press and fix the adhesive film at the feeding position X of the rotating adsorption unit 100 on the adsorption plate 107, prevent the adhesive film from slipping or deviating during cutting, and ensure the accuracy of the cutting of the adhesive film. Through the setting of the buffer block 220, the downward pressure of the first pressing plate 219 on the adsorption plate 107 can be buffered, so as to prevent the long-term hard contact between the two from affecting the preparation accuracy of the adhesive film.

[0046] As shown, Figure 13As shown, the cutting position pressing and fixing assembly is installed on the horizontal moving fixing plate 205 of the horizontal moving power device, and specifically includes the vertical hanging plate 221, the second pressing plate 222, the third pressing plate 223 and the fourth pressing plate 224. The vertical hanging plate 221 is provided with two groups of vertical installations at both ends of the horizontal moving fixing plate 205. The second pressing plate 222 is horizontally installed at the upper position of the vertical hanging plate 221. The third pressing plate 223 and the fourth pressing plate 224 are installed at the lower position of the vertical hanging plate 221 according to the second cutting gap position, and a gap is left for the second cutting knife 203 to cut; when the avoiding power device drives the cutting assembly of the horizontal moving power device to cut the film at the cutting position Y of the rotary adsorption unit 100, it further drives the cutting position pressing and fixing assembly to press and fix the film at the cutting position Y of the rotary adsorption unit 100 to assist cutting; specifically, the first pressing plate 219 and the second pressing plate 221 are configured to press and fix the film at the first cutting gap position, and the third pressing plate 223 and the fourth pressing plate 224 are configured to press and fix the film at the second cutting gap position; through the setting of the pressing and fixing mechanism, the cutting assembly can cut the film, thereby ensuring the precision of the film preparation.

[0047] As shown, Figure 14 When the film cutting at the cutting position Y is completed, the rotary adsorption unit 100 will rotate and transport the cut film to the discharging position Z; in this embodiment, a film conveying line (not shown in the figure) is arranged below the discharging position Z, which is used to convey the cut film to the next station; since there is a certain height difference between the rotary adsorption unit 100 and the film conveying line, in order to ensure the precision of the film placement, the rotary film making device includes a lifting unit, which includes a screw rod seat 307 and a lifting power device. The lifting power device includes a support frame 301, a support seat 302, a c motor 303, a c speed reducer 304, a screw rod 305 and a fixed seat 306. A mounting hole is formed in the top of the support frame 301, a bearing is mounted in the mounting hole, the screw rod 305 is sleeved in the bearing and is mounted on the support frame 301 through the fixed seat 306, the output end of the c motor 303 is connected with the input end of the c speed reducer 304, the c speed reducer 304 is mounted on the support frame 301 through the support seat 302 and is located at the upper position of the screw rod 305, the c speed reducer 304 is connected with the screw rod 305 through a shaft coupling, a sliding rail and a sliding block are oppositely arranged on one side of the support frame 301, the rotary adsorption unit 100 and the cutting unit 200 are mounted on the sliding block through the side plate 101, the screw rod seat 307 is mounted on the side plate 101 and is movably connected with the screw rod 305, when the c motor 303 drives the screw rod 306 to rotate, the side plate 101 is lifted relative to the support frame 301, thereby completing the discharging action of the film at the discharging position Z of the rotary adsorption unit 100.

[0048] Embodiment two: compared with embodiment one, the difference lies in that it further comprises a multifunctional operation station, which is located at the other side of the rotating adsorption unit 100. When the film needs to be preheated in the preparation process of the film, the multifunctional operation station can be provided with a heating unit (not shown in the figure) with a heating function to preheat the adsorption plate. Specifically, a heating lamp or a heating wire or the like can be used to realize the heating function. Alternatively, when the cutting unit 200 cuts the film, the film waste is pasted on the surface of the adsorption plate 107, and the multifunctional operation station can be provided with a blowing unit with a blowing function to blow the surface of the adsorption plate. Specifically, an air gun or a product such as a blowing block can be used to realize the blowing function. In this embodiment, the function of the multifunctional operation station should not be limited to heating or blowing.

[0049] Embodiment three: compared with embodiment one, the difference lies in that the adsorption plate 107 can be provided with five, six, seven or eight groups of support columns 110 installed on the roller 102 through the installation slot 108. By arranging multiple groups of adsorption plates 107, multiple operation stations can be increased to further increase the operation function, reduce the conveying path of the roller 102, and realize the preparation of multiple films to further increase the preparation efficiency of the film.

[0050] Film preparation method based on the above rotating film preparation device, comprising the following steps:

[0051] In the normal state, the film in the film roll is adsorbed on the adsorption plate 107 of the rotating adsorption unit 100 at the feeding station X, and the cutting assembly avoids the rotating path of the rotating adsorption unit 100 at the initial position;

[0052] Step one: the rotating adsorption unit 100 drives the adsorption plate 107 to rotate to convey the film from the feeding station X to the cutting station Y. At this time, the positions of the four groups of adsorption plates 107 are all changed;

[0053] Step two: when the film is conveyed to the cutting station Y, the cutting unit 200 drives the first pressing plate 219 downward to press on the film on the adsorption plate 107 at the feeding station X by using the feeding station pressing assembly; the second pressing plate 222, the third pressing plate 223 and the fourth pressing plate 224 are pressed on the film on the adsorption plate 107 at the cutting station Y by using the cutting station pressing assembly through the avoiding power device, and the second cutting knife 203 of the cutting assembly is driven to cut the film in the second cutting gap;

[0054] Step three: after the film at the feeding station X and the cutting station Y is pressed and fixed, the first cutting knife 202 of the cutting assembly is driven to cut the film in the first cutting gap by using the cutting unit through the telescopic power device, and the cutting assembly is driven to move horizontally by using the horizontal power device, thereby cutting the film in the first cutting gap and the second cutting gap.

[0055] Step four: when the film is cut, the first cutting knife 202 is retracted, and the cutting unit moves to avoid the rotating adsorption unit 100 through the avoiding power device;

[0056] Step five: after the cutting assembly avoids, the rotating adsorption unit 100 rotates and carries the cut film to the unloading position Z by the adsorption force of the adsorption plate 107, and in the process of rotation, the adsorption plate 107 located at the loading position X carries the new film from the loading position X to the cutting position Y;

[0057] Step six: after the rotating adsorption unit 100 carries the cut film to the unloading position Z, the film is lowered and placed on the film conveying line through the lifting unit, and after the film is placed, the lifting unit is raised again.

[0058] After the lifting is completed, the rotating film device repeats steps two, three, four, five and six to continuously produce the film in the film roll.
