Description

Technical Field

[0001] This disclosure relates to the field of skin closure device manufacturing, and particularly to a system, apparatus and method for manufacturing skin closure devices. Background Technology

[0002] Currently, for skin closure products of different lengths, it is necessary to customize various lengths of glue-applying fixtures, pressing fixtures, and punching fixtures. When producing products of different lengths, it is necessary to change the fixtures, resulting in low production efficiency; and the cost of various length fixtures is high.

[0003] The production of skin closure products requires the use of two types of adhesives, a first adhesive and a second adhesive, to solidify the product. In the existing technology, the first adhesive and the second adhesive are mixed and then applied. However, the first adhesive and the second adhesive tend to solidify and adhere to the fixture after mixing, which makes cleaning difficult. Furthermore, the first adhesive and the second adhesive have poor fluidity after mixing, making them difficult to apply. Summary of the Invention

In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this disclosure, and should not be construed as limiting this disclosure.

[0055] Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. In the description of this disclosure, it should be understood that the terms “center,” “longitudinal,” “lateral,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outer,” etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this disclosure and for simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure.

[0056] To address the problem that the first and second adhesives tend to solidify easily during application, resulting in poor coating effects, and to achieve continuous production of products of different lengths, embodiments of this disclosure provide a system, apparatus, and method for manufacturing skin closure devices, which will be described in detail below with reference to the accompanying drawings.

[0057] Embodiments of this disclosure provide a system for manufacturing skin closure devices, with reference to Figure 1 , Figure 1 A schematic diagram of a system for manufacturing a skin closure device according to an embodiment of the present disclosure is shown. The system for manufacturing a skin closure device includes: a film coating structure 1, adapted to apply a first adhesive to a film 41 in a film coating direction a; a feeding, coating, and pressing structure 2, adapted to apply a second adhesive to a part and press the part onto the film 41 in a pressing direction b; and a cutting structure 3, adapted to cut the film 41 into segments; the film coating structure 1, the feeding, coating, and pressing structure 2, and the cutting structure 3 are sequentially located on a transport path in the film transport direction d.

[0058] refer to Figure 1 In some embodiments, the system for manufacturing skin closure devices further includes a film transport structure 4, comprising a transport platform 42 adapted to place a film 41 and transport the film 41 in the transport direction d.

[0059] The following is combined Figures 2-8 The film coating structure provided in the embodiments of this disclosure will be described in detail.

[0060] refer to Figure 2 and Figure 3 A three-dimensional structural schematic diagram of the film coating structure according to an embodiment of the present disclosure is shown; Reference Figure 4 This is a cross-sectional view of the film coating structure according to an embodiment of the present disclosure when it is not in operation. The film coating structure includes: a glue storage cavity 125 for containing a first glue; a porous elastomer 13 in liquid communication with the glue storage cavity 125; a pressure plate 123 for supporting the porous elastomer 13; the pressure plate 123, the plate wall 126, and the connecting plate 11 define a glue tank 12 from the bottom, circumferentially, and top, respectively, and the glue storage cavity 125 and the porous elastomer 13 are located within the glue tank 12; an embossing notch 1231 disposed on the pressure plate 123; a coating head 131 that can protrude from the embossing notch 1231 to apply glue during use, and the coating head 131 in liquid communication with the porous elastomer 13; and an elastic element 124 disposed between the porous elastomer 13 and the connecting plate 11, adapted to provide a reverse restoring force to the porous elastomer 13 when the coating head 131 is compressed for glue application.

[0061] refer to Figure 2 and Figure 3 The pressure plate 123, the plate wall 126 and the connecting plate 11 define a glue tank 12. The upper part of the glue tank 12 is used to place the glue storage cavity 125 and the elastic element 124. The glue storage cavity 125 is used to hold glue. The lower part is used to place the porous elastomer 13 and apply glue through the cooperation of the pressure plate 123 and the glue application head 131.

[0062] In some embodiments, a filter screen 122 is provided between the porous elastomer 13 and the adhesive storage cavity 125, such as Figure 6 As shown, the filter screen 122 has filter pores 1221 distributed on it. The filter screen 122 is in contact with the porous elastomer 13 and the elastic element 124. When the porous elastomer 13 is compressed, the filter screen 122 can support and disperse the compressive force of the elastomer 124, so that the porous elastomer 13 is subjected to uniform compressive force.

[0063] Figure 4 A cross-sectional schematic diagram of the adhesive coating structure according to an embodiment of the present disclosure when it is not in operation is shown, with reference to... Figure 4A glue inlet 14 is provided on the connecting plate 11 to inject glue into the glue storage chamber 125. The glue injection method can be an external glue injection tube or a directly installed glue tank; it can be manual or automatic. During automatic glue injection, the amount of glue in the glue storage chamber 125 is monitored. To ensure pressure control in the glue storage chamber 125, the glue inlet 14 is closed after each injection and reopened for the next injection. Glue is replenished to the glue storage chamber 125 through the glue inlet 14, ensuring an uninterrupted supply of glue for the coating structure, thus achieving continuous coating.

[0064] Continue to refer to Figure 4 The connecting plate 11 is provided with an overflow port 15, and an overflow valve 16 is provided on the overflow port 15. The glue storage chamber 125 is connected to the atmosphere through the overflow port 15. The overflow valve 16 is used to control the pressure of the glue storage chamber 125 to ensure dynamic balance between the pressure of the glue storage chamber 125 and the imprinting pressure. Specifically, when imprinting is performed, the space of the glue storage chamber 125 becomes smaller and the pressure increases. When the pressure increases to the set pressure value of the overflow valve 16, the glue permeates through the porous elastomer 13 and the glue application head 131 under the pressure of the glue storage chamber 125 to reach the first glue application surface of the film for application. If the pressure of the glue storage chamber 125 continues to increase to a value greater than the set pressure value of the overflow valve 16, the overflow valve 16 will automatically open to release gas, reduce the pressure in the glue storage chamber 125, and bring the pressure in the glue storage chamber 125 back to the set pressure. When the glue with fixed flowability is subjected to the set pressure in the glue storage chamber 125, it will not drip when passing through the porous elastomer 13 with a fixed density. When it is squeezed and contacted, a layer of glue will be adhered to the coated surface. When no glue is applied, the porous elastomer 13 is in a relaxed state. The pressure in the glue storage chamber 125 is lower than the set pressure value of the overflow valve 16, and the overflow valve 16 is in a closed state.

[0065] By setting an overflow valve 16, the pressure in the glue storage chamber 125 is controlled to remain at the pressure value set by the overflow valve 16 when the first glue is applied to the film by the film coating structure. Since the size of the coating surface of the coating head 131 is fixed, the fluidity of the glue is fixed, and the density of the porous elastomer 13 is fixed, the set pressure value of the overflow valve 16 is set according to the size of the coating surface of the coating head 131, the fluidity of the glue, and the density of the porous elastomer 13. The amount of glue entering the coating head 131 through the porous elastomer 13 under this set pressure value is controlled so that no glue dripping occurs. That is, when the coating head 131 presses and contacts the film 41, a layer of glue is adhered to the first glue coating surface of the film 41, and the glue is full and the boundary is clear, without spreading.

[0066] In some embodiments, the shape and number of the injection port 14 and the overflow port 15 can be set according to actual needs.

[0067] In some embodiments, the elastic element 124 may be one or more. In some embodiments, the elastic element 124 is a spring. (Reference) Figure 4 Specifically, there are two elastic elements 124, which are respectively disposed between the glue injection port 14 and the filter screen 122, and between the overflow port 15 and the filter screen 122. The diameter of the glue injection port 14 is smaller than the diameter of the elastic element 124, and the diameter of the overflow port 15 is smaller than the diameter of the elastic element 124, so that one end of the elastic element 124 abuts against the periphery of the glue injection port 14 and the overflow port 15, and the other end abuts against the filter screen 122.

[0068] Figure 5 A cross-sectional schematic diagram of the structure of a porous elastomer and a dispensing head according to an embodiment of the present disclosure is shown. (Reference) Figure 5 In some embodiments, the porous elastomer 13 and the applicator head 131 are integrally formed. In some embodiments, the porous elastomer 13 and the applicator head 131 are provided with a through-hole 133, which connects the glue storage cavity 125 and the applicator head 131, allowing glue to flow between the glue storage cavity 125 and the applicator head 131 along the through-hole 133. The through-hole 133 passes through the porous elastomer 13 and exits through the overflow port 132 on the upper surface of the porous elastomer 13. Glue can flow from the glue storage cavity 125 into the through-hole 133 and, under certain pressure, permeate from the bottom of the applicator head 131 to contact the adhesive sheet 41. In some embodiments, the through-hole 133 preferably has a circular or square cross-section with a cross-sectional area of ​​4 mm². 2 Up to 9mm 2 The distance between the inner wall and the outer wall of the adhesive guide well 133 is 3-5mm, and the bottom thickness is preferably 3mm.

[0069] The number of adhesive guide wells 133 corresponds to the number of adhesive application heads 131, or multiple adhesive guide wells 133 can correspond to one adhesive application head 131, such as... Figure 5 As shown, one glue applicator 131 corresponds to two glue guide wells 133.

[0070] By providing a guide well 133 in the porous elastomer 13, adhesive can be quickly replenished to the coating head 131 during adhesive application in the film coating structure, thereby ensuring efficient adhesive application.

[0071] In some embodiments, there are multiple applicator heads 131, multiple embossing notches 1231, and an adhesive storage cavity 125 for supplying adhesive to the multiple applicator heads 131 for applicator application. In some embodiments, such as Figure 3As shown, there are two glue-applying heads 131 and two imprinting notches 1231. Of course, the number of glue storage chambers 125, glue-applying heads 131, imprinting notches 1231, and even glue guide wells 133 can be set according to actual needs, and this should not limit the scope of protection of this disclosure.

[0072] In some embodiments, the bottom surface of the glue tank 12 is provided with a sealing strip groove 1221, and a sealing strip 121 is placed in the sealing strip groove 1221 to prevent the glue in the glue tank 12 from overflowing from the boundary.

[0073] Figure 7 A cross-sectional schematic diagram of the film coating structure according to an embodiment of the present disclosure is shown in operation. Since film 41 is not part of the film coating structure, it is shown as a dashed line in the figure. Reference Figure 7 When the adhesive application structure is in operation, the height h' of the adhesive application head 131 above the bottom surface of the pressure plate 123 is 1-3 mm to facilitate adhesive application. In some embodiments, refer to Figure 4 When the adhesive application structure is not in operation, the height h of the adhesive application head 131 protruding from the bottom surface of the pressure plate 123 is 3-5mm.

[0074] In some embodiments, the porous elastomer 13 and the adhesive applicator 131 are polymer materials with a hollow honeycomb effect. In some embodiments, the porous elastomer 13 and the adhesive applicator 131 are sponges, which have good adhesive retention properties, ensuring continuous adhesive application and improving adhesive application efficiency.

[0075] In this embodiment of the disclosure, the glue applicator is made of an elastic material and its shape is easy to process. That is, the pattern and shape of the glue applicator 131 can be designed according to actual needs to be applied to the application of glue for conventional patterns, complex patterns and special patterns.

[0076] In other embodiments, the porous elastomer 13 and the adhesive applicator 131 may be non-monolithically formed and made of different materials, which should not unduly limit the scope of this disclosure.

(See reference) Figure 8 The film coating structure moves in the film coating direction a, and the coating head 31 presses and leaves a first adhesive layer 411 on the first adhesive coating surface of the film 41.

Reference Figure 10 The clamping box 21 has a defined internal space, which includes a pressure rod groove 252, a clamping channel 22, and a push rod groove 232. One end of the clamping box 21 has a discharge port 211 that communicates with the pressure rod groove 252. The clamping channel 22 has one end open to the surface of the other end of the clamping box 21 and the other end communicates with the push rod groove 232, thereby providing space for the part to move from the clamping channel 22 into the push rod groove 232. The push rod groove 232 communicates with the clamping channel 22 and one end is connected to the pressure rod groove 252.

[0081] refer to Figure 10 In some embodiments, the transport structure 23 includes: a push rod groove 232 adapted to provide a channel for the movement of a part; and a push rod 231 adapted to push the part within the push rod groove 232 to the pressure rod groove 252.

[0082] In some embodiments, one end of the push rod 231 is in the push rod groove 232, and the other end protrudes from the clamping box 21; when the push rod 231 can be moved by the push force applied by the drive mechanism, the other end of the push rod 231 may not protrude from the clamping box 21.

[0083] In some embodiments, the clamping channel 22 includes a first channel extending in a first direction y, and the push rod groove 232 includes a second channel extending in a second direction x. The first direction y and the second direction x are not parallel. A transition portion 233 is provided at the intersection of the first channel and the second channel so that the part is deflected when it falls from the first channel into the second channel.

[0084] In some embodiments, the front end of the push rod 231 is provided with a deflection chamfer 2312, which cooperates with the transition portion 233 to deflect the part when it falls from the first channel into the second channel. Specifically, the part enters the first channel in the first direction y of the clamping channel 22, and under the action of the deflection chamfer 2312, it is deflected in the transition portion 233 and enters the second path in the second direction x of the push rod groove 232. The push rod 231 pushes the part from the push rod groove 232 to the pressure rod groove 252.

[0085] refer to Figure 10The pressing structure 25 includes a pressure rod 251 and a pressure rod groove 252. The pressure rod 251 is used to push a part to move within the pressure rod groove 252. The pressure rod groove 252 is adapted to accommodate the pressure rod 251 and communicates with the push rod groove 232 to receive the part pushed from the push rod 231 into the pressure rod groove 252. The pressure rod groove 252 is connected to the discharge port 211. The pressure rod 251 pushes the part within the pressure rod groove 252 until the second adhesive coating surface of the part passes through the discharge port 211 and protrudes from the bottom surface of the clamping box 21 for adhesive application. After the second adhesive coating is applied to the part, the pressure rod 251 presses the part onto the first adhesive coating surface of the adhesive sheet.

[0086] In some embodiments, the pressure rod 251 is located within the pressure rod groove 252, with one end protruding from the clamping box 21; when the pressure rod 251 can be moved by a driving mechanism applying a thrust, the other end of the pressure rod 251 may not protrude from the clamping box 21.

[0087] In some embodiments, the inner surface of the pressure rod groove 252, extending from the connection point between the pressure rod groove 252 and the push rod groove 232 to the discharge port 211, is covered with a friction material 2521. This material increases the friction between the part and the inner surface of the pressure rod groove 252, causing the part to be suspended within the pressure rod groove 252 due to the frictional force exerted by the friction material 2521. The friction material can be silicone, other rubbers, or materials with good elasticity and high friction.

[0088] Figure 11This diagram shows a partially enlarged cross-sectional view of the clamping box of the loading, gluing, and pressing structure without a transport structure according to an embodiment of the present disclosure. The clamping channel 22 is located within the clamping box 21. One end of the clamping channel 22 opens onto the surface of one end of the clamping box 21, and the other end communicates with the discharge port 211, which is located on the surface of the other end of the clamping box 21. The inner diameter of the clamping channel 22 is approximately equal to the size of the second gluing surface 261 of the part 26, allowing the part 26 to be inserted into the clamping channel 22 with the second gluing surface 261 facing it. The pressing structure 25 includes a pressure bar groove 252 and a pressure bar 251 adapted to move within the pressure bar groove 252. The pressure bar groove 252 is the clamping channel 22. The inner surface of the pressure bar groove 252 near the discharge port 211 is covered with a friction material 2521 to increase the friction between the part 26 and the inner surface of the pressure bar groove 252, thereby suspending the part 26 within the pressure bar groove 252. Specifically, the second adhesive-coated surface 261 of part 26 is inserted into the clamping channel 22, and is suspended in the pressure rod groove 252 due to the frictional force of the friction material 2521. The pressure rod 251 pushes part 26 towards the discharge port 211 within the pressure rod groove 252 until its second adhesive-coated surface 261 protrudes from the bottom surface of the clamping box 1 through the discharge port 211 for adhesive application. After the adhesive application is completed on part 26, the pressure rod 251 presses the second adhesive-coated surface 261 of part 26 together with the first adhesive-coated surface of the film.

[0089] refer to Figure 9 The adhesive application structure 24 includes: a crossbeam 241, a roller 242, a drive mechanism 243, and an adhesive storage tank 244. The crossbeam 241 has a through hole 2411 through which the clamping box 21 can pass. The roller 242 includes a roller shaft 2422 and a roller brush 2421 driven by the roller shaft 2422 to rotate. The roller brush 2421 is adapted to apply adhesive to parts located at the discharge port 211.

[0090] In some embodiments, the drive mechanism 243 is adapted to drive the movement of the roller 242, thereby driving the roller brush 2421 to contact the second adhesive application surface of the part protruding from the outlet 211 of the clamping box 21 to apply the second adhesive, and driving the roller brush 2421 to move to the adhesive storage tank 244 for replenishing adhesive and waiting for the next adhesive application.

[0091] In some embodiments, the drive mechanism 243 includes: a slide rail 2431 disposed on both sides of the crossbeam 241, adapted to provide a track for the roller 242 to move; and a pulley system including a plurality of pulleys 2432 and a pull rope 2433, one end of the pull rope 2433 being embedded in the roller 2422, and the pull rope 2433 driving the roller 242 to move along the slide rail 2431 as the pulleys 2432 roll.

[0092] In some embodiments, the glue storage tank 244 is located at one end of the crossbeam 241, adjacent to the through hole 2411, and is adapted to accommodate the second glue and the roller 242, which replenishes the glue in the glue storage tank 244.

[0093] refer to Figures 12-13 , Figure 12 A partially enlarged perspective view of the adhesive storage tank according to an embodiment of the present disclosure is shown. Figure 13 A partially enlarged cross-sectional view of the adhesive reservoir according to an embodiment of the present disclosure is shown. The adhesive reservoir 244 has a scraping edge 2441 on the edge near the through hole 2411, suitable for scraping off excess second adhesive from the roller 242. The height of the scraping edge 2441 is adjustable. Depending on the adhesive application requirements of different parts, adjusting the height of the scraping edge 2441 changes the contact area between the scraping edge 2441 and the roller brush 2421, thereby controlling the amount of second adhesive scraped off the roller brush 2421 by the scraping edge 2441. This ensures that the amount of second adhesive on the roller brush 2421 is suitable for a single application, avoiding excessive adhesive causing dripping or insufficient adhesive leading to incomplete application.

[0094] In some embodiments, depending on the number and distribution requirements of the parts in the production of film products with adhesive parts, there may be multiple clamping channels 21, transport structures 23, pressing structures 25, and discharge ports 211, arranged in an axially symmetrical manner.

[0095] In some embodiments, the roller brush 2421 is made of sponge material.

(Reference) Figure 15The equipment for manufacturing skin closure devices includes the system for manufacturing skin closure devices described in the foregoing embodiments, and further includes: a control mechanism C100, a film coating drive mechanism C101, a feeding, coating, and pressing drive mechanism C102, a cutting drive mechanism C103, and a film transport drive mechanism C104. The control mechanism C100 is adapted to control the film coating drive mechanism C101, the feeding, coating, and pressing drive mechanism C102, the cutting drive mechanism C103, and the film transport drive mechanism C104.

[0099] In some embodiments, the control mechanism C100 controls the film coating drive mechanism C101 to drive the film coating structure 1 to apply the first adhesive to the film. The film coating drive mechanism C101 can be driven by a motor, a cylinder, or a hydraulic system.

[0100] In some embodiments, the control mechanism C100 controls the feeding, gluing, and pressing drive mechanism C102 to drive the feeding, gluing, and pressing structure 2 to apply the second adhesive to the part and press it onto the adhesive sheet. The feeding, gluing, and pressing drive mechanism C102 can be driven by a motor, a cylinder, or hydraulically.

[0101] In some embodiments, the control mechanism C100 controls the cutting drive mechanism C103 to drive the cutting structure 3 to cut the film into segments of the required length. The cutting drive mechanism C103 can be driven by a motor, a cylinder, or hydraulically.

[0102] In some embodiments, the control mechanism C100 controls the film transport drive mechanism C104 to drive the film transport structure 4 to transport the film. The film transport drive mechanism C104 can be driven by a motor, a cylinder, or hydraulically.

[0103] Embodiments of this disclosure also provide a method for manufacturing a skin closure device, wherein the method for manufacturing the skin closure device is performed using the equipment for manufacturing skin closure devices described in the foregoing embodiments. Figure 16 A schematic flowchart illustrating a method for manufacturing a skin closure device according to an embodiment of the present disclosure is shown. (Reference) Figure 16 In S1, a first adhesive is applied to the film, and the film adhesive application drive mechanism is controlled to drive the film adhesive application structure to apply the first adhesive to the film; in S2, a second adhesive is applied to the part and pressed onto the film, and the feeding adhesive application and pressing drive mechanism is controlled to drive the feeding adhesive application and pressing structure to apply the second adhesive to the part and press it onto the film; in S3, the film is cut, and the cutting drive mechanism is controlled to drive the cutting structure to cut the film into segments.

[0104] In some embodiments, the method for manufacturing a skin closure device further includes: transferring a film, controlling a film transfer drive mechanism to drive the film transfer structure to transfer the film in a pulse manner, and sequentially transferring the film to the film coating structure, the loading and coating pressing structure, and the cutting structure.

[0105] Figure 17 A schematic flowchart illustrating the application of a first adhesive in a method for manufacturing a skin closure device according to an embodiment of the present disclosure is shown. (Reference) Figure 17 In step S101, the first adhesive is injected into the storage cavity through the injection port, and the injection port is closed after the injection is completed.

[0106] In some embodiments, the injection of the first adhesive can be automatic or manual, with each injection completed once, and the amount of the first adhesive injected is sufficient for the production of one batch of products.

[0107] refer to Figure 17 In S102, the film transport drive mechanism is controlled to drive the film transport structure to move the first adhesive coating surface of the film to below the film coating structure and stop there. At this time, the first adhesive coating surface of the film is located directly below the imprinting exit of the film coating structure so that the coating head can be pressed out from the imprinting notch to the first adhesive coating surface for coating.

[0108] refer to Figure 17 In S103, the porous elastomer is extruded, thereby increasing the pressure in the adhesive storage cavity of the film coating structure to be greater than atmospheric pressure. Due to the pressure difference between the adhesive storage cavity pressure and atmospheric pressure, the first adhesive flows from the adhesive storage cavity to the first adhesive coating surface of the film to apply the first adhesive.

[0109] In some embodiments, an overflow valve is provided at the overflow port. When the pressure in the glue storage chamber increases to the pressure value set by the overflow valve, the overflow valve automatically opens to release the pressure and maintain the pressure in the glue storage chamber. As a result, the pressure difference between the glue storage chamber and the atmospheric pressure is stable, and the first glue flows to the first glue coating surface under a stable pressure difference. This ensures that the amount of first glue applied is appropriate and avoids the situation of excessive glue causing dripping or insufficient glue causing incomplete coating.

[0110] refer to Figure 17 In S104, the film coating drive mechanism is controlled to drive the film coating structure to move upward until it is no longer in contact with the film, so that the film after the first adhesive coating is completed can be transferred by the film transfer structure to the feeding coating and pressing structure for the second adhesive coating and pressing operation.

(See reference...) Figure 18In S201, the film transport drive mechanism is controlled to drive the film transport structure to move the film after the first adhesive coating is completed to the bottom of the feeding adhesive pressing structure and stop it, so that the feeding adhesive pressing structure can apply the second adhesive to the part and press it onto the first adhesive coating surface of the film.

[0112] refer to Figure 18 In S202, the feeding, gluing, and pressing drive mechanism is controlled to drive the parts into the clamping channel, and the parts move to the transport structure within the clamping channel.

[0113] refer to Figure 18 In S203, the feeding, gluing, and pressing drive mechanism is controlled to drive the transport structure to transport the parts to the pressing structure.

[0114] In some embodiments, the part moves to a transition portion due to gravity along a first channel extending in a first direction in the clamping channel, and deflects at the transition portion to enter the push rod groove of the transport structure. The push rod of the transport structure then moves the part along a second channel extending in a second direction within the push rod groove into the pressure rod groove.

[0115] refer to Figure 18 In S204, the feeding and gluing pressing drive mechanism is controlled to drive the pressing rod of the pressing structure to push the part until the second glue coating surface of the part passes through the discharge port and protrudes from the bottom surface of the clamping box, ready for the second glue to be applied.

[0116] refer to Figure 18 In S205, the feeding, gluing, and pressing drive mechanism is controlled to drive the part gluing structure to apply glue to the second glue-applying surface of the part.

[0117] In some embodiments, the part adhesive application structure applies the second adhesive to the part in the following manner: A pulley rotates, driving a rope to pull a roller along a slide rail from the adhesive reservoir towards the clamping box. The second adhesive-coated surface of the part protrudes from the bottom surface of the clamping box. The roller moves to a position below the part, contacts the second adhesive-coated surface, and applies the second adhesive to it. After the second adhesive application is completed, the pulley rotates again, driving the rope to pull the roller back into the adhesive reservoir for replenishment of the second adhesive, awaiting the next application.

[0118] refer to Figure 18 In S206, the feeding, coating, and pressing drive mechanism is controlled to drive the feeding, coating, and pressing structure to move towards the film to the discharge port and stop directly above the first coating surface of the film.

[0119] refer to Figure 18 In S207, the feeding, gluing, and pressing drive mechanism is controlled to drive the pressing rod of the pressing structure to push the part out of the discharge port and press it onto the first gluing surface of the film.

[0120] Figure 19 A schematic diagram of the structure during a cutting operation according to an embodiment of the present disclosure is shown. (Reference) Figure 19 and Figure 16 In S3, the film transport drive mechanism is controlled to drive the film transport drive structure to transport the film 41 to the area below the cutting structure and stop there. At this time, the cutting seam 411 on the film 41 is located directly below the blade 32. The cutting drive mechanism is controlled to drive the cutting structure to move towards the film 41 until the blade 32 contacts the cutting seam 411 and cuts the film 41 at the cutting seam 411, thereby obtaining the film of the required length.
