Description

Technical Field

[0001] This invention relates to the technical field of automatic processing of injection molded products, and in particular to an automatic film-applying device and an automatic sprue cutting and film-applying integrated machine. Background Technology

[0002] After the product injection molded, a protective film needs to be applied to the surface to protect it from scratches. During the processing, the injection molded product needs to have its sprue cut off before being placed on a film applicator to apply the protective film.

[0003] like Figure 1 As shown, when the protective film is a single-unit protective film, multiple single-unit protective films are adhered to the material strip, and each single-unit protective film needs to be precisely attached to the position of each product. Therefore, the film application accuracy requirement for the film application device is high when applying film to products.

[0004] Existing laminating machines use multiple rollers to tension the protective film and then adjust the position of the rollers to regulate its position. However, when applying individual protective films, problems arise such as unevenness of the film and inaccurate application, affecting the quality and efficiency of the application. Furthermore, these machines are not suitable for applying individual protective films, as illustrated in the technical solution disclosed in prior art document CN201811268630.1. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic film application device and an automatic water outlet cutting and film application integrated machine that can apply film smoothly, with high precision in film application position and high compatibility.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An automatic film applicator includes a worktable, a base adjustment mechanism, a feeding mechanism, an applicating mechanism, a support frame, and a fixture. The worktable has a mounting boss, and the fixture is mounted on the mounting boss. The base adjustment mechanism is connected to the worktable and slidably connected to the support frame. The feeding mechanism includes a feeding structure, a roller structure, a suction structure, and a pressing structure connected sequentially to the support frame. The applicating mechanism includes a peeling table assembly and an mounting arm structure slidably connected to the support frame.

[0008] The fixture is used to install the product; the base adjustment mechanism is used to adjust the position of the support frame; the feeding structure is used to hang the protective film assembly; the roller structure is used to tension and guide the protective film assembly extended from the feeding structure; the suction flattening structure is used to flatten the protective film assembly; the pressing structure is used to press the protective film assembly so that both sides of the protective film assembly are respectively attached to the peeling platform assembly and the suction flattening structure; the peeling platform assembly is used to place and peel off the protective film assembly; the mounting arm structure is used to install the protective film assembly.

[0009] In one embodiment, the suction-flattening structure includes a vacuum adsorption component, limiting blocks, and a vacuum pump. The vacuum adsorption component has a vacuum chamber inside, and the surface of the vacuum adsorption component has adsorption holes. The back of the vacuum adsorption component also has two vacuum air inlets. The two vacuum air inlets, the vacuum chamber, and the adsorption holes are connected in sequence. The two vacuum air inlets are connected to the output end of the vacuum pump. The vacuum pump is used to control the adsorption holes to draw air. There are two limiting blocks, which are arranged on both sides of the vacuum adsorption component.

[0010] In one embodiment, the stripping table assembly includes a sliding frame assembly and a stripping platform. The sliding frame assembly includes a sliding seat and a stripping cylinder. The sliding seat is connected to the output end of the stripping cylinder, and the stripping cylinder is used to control the extension and retraction of the sliding seat. The stripping platform is connected to the sliding seat and is disposed between the mounting boss and the clamping structure.

[0011] In one embodiment, the stripping platform assembly further includes a strip pressing block, which is disposed on the side of the stripping platform near the support frame. The strip pressing block has a strip guide groove and a strip reading hole. The strip guide groove is located between the strip pressing block and the stripping platform, and the strip reading hole is connected to the strip guide groove.

[0012] In one embodiment, the roller structure includes a first roller assembly, a second roller assembly, and a recovery roller assembly connected sequentially to the support frame. The recovery roller assembly is disposed below the flattening structure. One end of each of the first roller assembly, the second roller assembly, and the recovery roller assembly is connected to the output end of a drive motor. The drive motor can drive the first roller assembly, the second roller assembly, and the recovery roller assembly to rotate relative to the support frame, thereby controlling the movement of the protective film assembly through the roller structure.

[0013] In one embodiment, the clamping structure includes a clamping plate, a width adjusting block, and a clamping cylinder. The clamping cylinder is connected to the support frame, and the clamping plate is connected to the output end of the clamping cylinder. The clamping cylinder is used to control the lifting assembly to slide up and down. The clamping plate has an adjusting block groove, and the width adjusting block is installed in the adjusting block groove.

[0014] In one embodiment, the mounting arm structure includes a guide rail assembly, a suction head assembly, and a guide rail cylinder. The guide rail assembly is fixed to the support frame, the suction head assembly is slidably connected to the guide rail assembly, and the suction head assembly is also connected to the output end of the guide rail cylinder. The guide rail cylinder is connected to the guide rail assembly and is used to control the sliding of the suction head assembly.

[0015] In one embodiment, the suction head assembly includes a pressing member, a first auxiliary material suction head, a second auxiliary material suction head, a cylinder slide, and a sliding cylinder. The pressing member is slidably connected to the guide rail assembly. The first auxiliary material suction head and the cylinder slide are both connected to the end of the pressing member opposite to the guide rail assembly. The second auxiliary material suction head is slidably connected to the cylinder slide, and the cylinder slide is connected to the output end of the sliding cylinder.

[0016] In one embodiment, the feeding structure includes a support arm, a blocking member, a connecting rod, and an adjusting assembly. There are two blocking members. The support arm is connected to the support frame. The connecting rod is connected to the support arm. The connecting rod passes through the blocking member and the adjusting assembly. The adjusting assembly is connected to the connecting rod and is located on one side of one of the blocking members.

[0017] An automatic sprue cutting and film application integrated machine includes a sprue cutting device, a conveying device, and a film application device as described in any of the above embodiments. The sprue cutting device and the conveying device are both installed on the workbench. The two ends of the conveying device are respectively adjacent to the sprue cutting device and the film application device. The sprue cutting device is used to cut the sprue of the product, and the conveying device is used to grab and move the fixture containing the product.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] The aforementioned automatic film-applying device and automatic sprue cutting and film-applying integrated machine use multiple individual protective films to adhere to the protective modules on the material strip and match the fixture for film application. This saves the process of cutting protective film groups and improves production efficiency.

[0020] The position of the protective film assembly can be adjusted in real time by the tensioning roller structure. The protective film assembly is adsorbed by the suction structure, so that the individual protective films on the protective film assembly are spread out on the surface of the suction structure, thereby avoiding wrinkles in the protective film assembly during film application and improving the quality of film application. The protective film assembly is pressed by the pressing structure, so that the protective film assembly is taut and adhered to the peeling table assembly, thereby making the protective film assembly flat in the fixed position on the peeling table assembly. This ensures that the mounting arm structure accurately picks up the individual protective films on the protective film assembly and accurately installs the individual protective films on the product surface.

[0021] Different specifications of protective film assemblies can be installed on the feeding structure. The roller structure, suction structure and pressing structure can be adapted to adjust the position of the protective film assembly on the peeling table assembly. The base adjustment mechanism can precisely adjust the position of the product and the mounting arm structure according to different product specifications, so that the automatic film application device has high film application accuracy and compatibility.

[0022] The sprue cutting device can be adapted to cut sprues for different products, and the film application device can apply film to products of different specifications with high precision. This makes the automatic sprue cutting and film application integrated machine compatible with products of different specifications for automatic sprue cutting and film application production line processing, improving the versatility and production efficiency of the automatic sprue cutting and film application integrated machine.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0038] like Figure 1 and Figure 2As shown, an automatic film applicator 10a according to one embodiment includes a worktable 100, a base adjustment mechanism 200, a feeding mechanism 300, an applicating mechanism 400, a support frame 500, and a fixture 600. The worktable 100 has a mounting boss 110 protruding from it, and the fixture 600 is mounted on the worktable 100. The protective film assembly 20 includes multiple individual protective films 20a adhered to a material strip 20b. In this embodiment, each individual protective film 20a is used to be applied to a product. Before application, the product is placed in the fixture 600, and then the individual protective films 20a separated from the material strip 20b are applied to the product. Different fixtures 600 are used for different products.

[0039] like Figures 2 to 4 As shown, further, the base adjustment mechanism 200 is connected to the workbench 100 and slidably connected to the support frame 500. The feeding mechanism 300 includes a feeding structure 310, a roller structure 320, a suction structure 330, and a pressing structure 340 sequentially connected to the support frame 500. The pasting mechanism 400 includes a peeling table assembly 410 and a mounting arm structure 420, both of which are slidably connected to the support frame 500. The base adjustment mechanism 200 is used to adjust the position of the support frame 500. The feeding structure... 310 is used to hang the protective film assembly 20; the roller structure 320 is used to tension and guide the protective film assembly 20 led out from the feeding structure 310, so that the protective film assembly 20 is taut and moves as the roller structure 320 rotates; the suction structure 330 is used to suction the protective film assembly 20; the pressing structure 340 is used to press the protective film assembly 20 so that both sides of the protective film assembly 20 are respectively attached to the peeling table assembly 340 and the suction structure 330; the peeling platform assembly 410 is used to place and peel the protective film assembly 20; the mounting arm structure 420 is used to pick up and install the protective film assembly 20.

[0040] In this embodiment, the stripping table assembly 410 slides relative to the support frame 500 in a direction parallel to the X-axis, and the mounting arm structure 420 slides relative to the support frame 500 in a direction parallel to the Z-axis.

[0041] In this embodiment, the protective film assembly 20 is hung on the feeding structure 310, and one end of the protective film assembly 20 is led out from the feeding structure 310 and passes through the roller structure 320, the suction flattening structure 330 and the pressing structure 340 in sequence. When the protective film assembly 20 passes through the suction structure 330, the suction holes 3301 of the suction structure 330 draw in air, causing the protective film assembly 20 to adhere tightly to the surface of the suction structure 330. The pressing structure 340 presses down, causing one end of the protective film assembly 20 to adhere tightly to the suction structure 330, and the other end of the protective film assembly 20 to adhere tightly to the peeling table assembly 410. When peeling and sucking up the monomer protective film 20a, the peeling table assembly 410 slides out, causing the protective film assembly 20 on the peeling table assembly 410 to move to below the mounting arm structure 420. The mounting arm structure 420 moves downward to suck up the monomer protective film 20a on the protective film assembly 20. The mounting arm structure 420 rises, causing the monomer protective film 20a to separate from the material strip 20b of the protective film assembly 20. When pasting the monomer protective film 20a, the peeling table assembly 410 retracts and slides, while the roller structure 320 rotates and curls the material strip 20b. The mounting arm structure 420 descends, pasting the monomer protective film 20a onto the product. The distance between the feeding mechanism 300 and the mounting boss 110 can be adjusted by the base assembly 200, thereby adjusting the distance between the different product fixtures 600 and the mounting arm structure 420.

[0042] The aforementioned automatic film-applying device 10a, in conjunction with the fixture 600, adheres multiple individual protective films 20a to the protective module on the material belt 20b. This eliminates the need for cutting the protective film assembly 20, improving production efficiency. The position of the protective film assembly 20 can be adjusted in real time via the roller structure 320 for tensioning. The suction structure 330 adsorbs the protective film assembly 20, causing the individual protective films 20a on the assembly to unfold on its surface, thus preventing wrinkles during application and improving quality. The pressing structure 340 presses the protective film assembly 20, ensuring it is taut against the peeling table assembly 410, thereby... The protective film assembly 20 is laid flat on the peeling table assembly 410 and fixed in a fixed position, so that the mounting arm structure 420 can accurately pick up the individual protective film 20a on the protective film assembly 20 and accurately position the individual protective film 20a on the product surface. Protective film assemblies 20 of different specifications can be installed on the feeding structure 310. The roller structure 320, the suction structure 330 and the pressing structure 340 can be adapted to adjust the position of the protective film assembly 20 on the peeling table assembly 410 according to different specifications of products. The base adjustment mechanism 200 can precisely fine-tune the position of the product and the mounting arm structure 420 according to different specifications of products, so that the automatic film application device 10a has high film application accuracy and compatibility.

[0043] like Figure 2 and Figure 3As shown, in one embodiment, the base adjustment mechanism 200 includes a first base assembly 210 and a second base assembly 220. The first base assembly 210 is connected to the worktable 100, and the second base assembly 220 is slidably connected to the first base assembly 210. A support frame 500 is slidably connected to the upper surface of the second base assembly 220. The direction in which the support frame 500 is slidably connected to the second base assembly 220 is a first sliding direction, and the direction in which the second base assembly 220 is slidably connected to the first base assembly 210 is a second sliding direction. The second sliding direction is perpendicular to the first sliding direction. The support base 210 is connected to one side of the support frame 500. In this embodiment, by moving the support frame 500 in the first sliding direction, the position of the second base assembly 220 causes the support frame 500 to move in the second sliding direction, thereby adjusting the distance between the support frame 500 and the mounting boss 110 to accommodate different sizes of film for application. The second base assembly 220 slides relative to the first base assembly 210 in a direction parallel to the Y-axis, and the support frame 500 slides relative to the second base assembly 220 in a direction parallel to the X-axis.

[0044] like Figure 3 and Figure 4 As shown, in one embodiment, the first base assembly 210 is further provided with a horizontal scale groove 2101, and the bottom of the support frame 500 is further provided with a vertical scale groove 501. In this embodiment, during the film application process, the mounting arm structure 420 can be precisely fine-tuned through the horizontal scale groove 2101 and the vertical scale groove 501, thereby improving the accuracy of the film application. At the same time, the operator records the corresponding data, and when applying film to the same product again, the corresponding data can be quickly and accurately adjusted.

[0045] like Figure 5As shown, in one embodiment, the suction-flattening structure 330 includes a vacuum adsorption component 331, a limiting block 332, and a vacuum pump. The vacuum adsorption component 331 has a vacuum chamber 3302 inside, and an adsorption hole 3301 is formed on the surface of the vacuum adsorption component 331. Two vacuum air inlets 3303 are also formed on the back of the vacuum adsorption component 331. The two vacuum air inlets 3303, the vacuum chamber 3302, and the adsorption hole 3301 are connected. The two vacuum air inlets 3303 are connected to the output end of the vacuum pump. The vacuum pump is used to control the adsorption hole 3301 to draw air. There are two limiting blocks 332, which are arranged on both sides of the vacuum adsorption component 331. In this embodiment, there are multiple adsorption holes 3301, which are spaced apart on the vacuum adsorption component 331. All adsorption holes 3301 are connected to the vacuum chamber 3302. By controlling the suction and release of air by the vacuum adsorption component 331, the protective film assembly 20 can be adsorbed or released, so that the protective film assembly 20 is flattened, avoiding bending and creases when the protective film assembly 20 moves. The distance between the two limiting blocks 332 can be slidably adjusted so that the protective film assembly 20 is properly placed between the two limiting blocks 332, thereby reducing the shaking of the protective film assembly 20.

[0046] However, when the protective film assembly 20 completely covers the surface of the suction structure 330, there is a problem of excessive electrostatic attraction between the protective film assembly 20 and the surface of the suction structure 330. When the roller structure 320 moves the protective film assembly 20, the excessive electrostatic attraction between the protective film assembly 20 and the suction structure 330 causes the protective film assembly 20 to be torn during movement. To avoid the problem of the protective film assembly 20 being torn during movement, such as... Figure 5As shown, in one embodiment, the flattening structure 330 further includes a backflush pump, and the vacuum adsorption component 331 is provided with a backflush through hole 3304. The inflation end of the backflush pump is connected to the backflush through hole 3304, and the backflush through hole 3304 is disposed on the surface of the flattening structure 330. Further, there are multiple backflush through holes 3304, which are spaced apart and all connected to the backflush pump. Each backflush through hole 3304 is disposed adjacent to the adsorption hole 3301. In this embodiment, before the roller structure 320 moves the protective film assembly 20, the backflush pump can be inflated through the backflush air inlet 3305, allowing the backflush airflow to enter the backflush through hole 3304 and spray onto the protective film assembly 20. This facilitates the smooth separation of the protective film assembly 20 from the vacuum adsorption component 331, preventing the protective film assembly 20 from being torn due to excessive electrostatic adsorption force between it and the flattening structure 330. Specifically, four backflush through holes 3304 can be provided, which are distributed at the four corners of the surface of the vacuum adsorption component 331 and connected to the output end of the backflush air pump. When the protective film assembly 20 covers the entire surface of the suction structure 330, by inflating the four backflush through holes 3304, the protective film assembly 20 can be effectively and quickly separated from the four corners of the surface of the vacuum adsorption component 331, thereby avoiding the problem of breakage caused by excessive electrostatic adsorption force between the protective film assembly 20 and the vacuum adsorption component 331.

[0047] like Figure 3 and Figure 7 As shown, in one embodiment, the stripping table assembly 410 includes a sliding frame assembly 411 and a stripping platform 412. The sliding frame assembly 411 includes a sliding seat 4111 and a stripping cylinder 4112. The sliding seat 4111 is connected to the output end of the stripping cylinder 4112, which controls the extension and retraction of the sliding seat 4111. The stripping platform 412 is connected to the sliding seat 4111 and is disposed between the mounting boss 110 and the clamping structure 340. In this embodiment, the sliding seat 4111 slides relative to the support frame 500 in a direction parallel to the X-axis, and the sliding seat 4111 drives the stripping platform 412 to slide relative to the support frame 500 in a direction parallel to the X-axis. The peeling cylinder 4112 is supplied with air pressure to control the movement of the sliding seat 4111, so that the peeling platform 412 connected to the sliding seat 4111 moves away from the flat platform and closer to the bottom of the mounting arm structure 420. The mounting arm structure 420 can accurately pick up the single protective film 20a in the protective film group 20 above the peeling platform 412. The peeling cylinder 4112 controls the sliding seat 4111 to drive the peeling platform 412 closer to the pressing structure 340, so that the peeling platform 412 is misaligned with the mounting arm structure 420. After the mounting arm structure 420 picks up the single protective film 20a, it moves downward and closer to the mounting boss 110, so that the single protective film 20a is accurately attached to the product surface.

[0048] like Figure 7 and Figure 8 As shown, in one embodiment, the stripping platform assembly 410 further includes a strip pressing block 413. The strip pressing block 413 is disposed on the side of the stripping platform 412 near the support frame 500. The strip pressing block 413 has a strip guiding groove 4101 and a strip reading hole 4102. The strip guiding groove 4101 is located between the strip pressing block 413 and the stripping platform 412, and the strip reading hole 4102 is connected to the strip guiding groove 4101. In this embodiment, one side of the protective film assembly 20 is embedded in the material guide groove 4101, so that the protective film assembly 20 will not deviate when moving on the peeling platform 412. The side of the material strip 20b of the protective film assembly 20 is provided with spaced material strip holes. A detection device can be installed on the peeling platform 412 to align with the material strip reading hole 4102 to identify the material strip holes in the protective film assembly 20. The detection device is connected to the drive motor of the roller structure 320, and the detection device controls the rotation of the drive motor, thereby controlling the movement of the material strip 20b of the protective film assembly 20. When the material strip hole is aligned with the material strip reading hole 4102, the movement stops, so that each individual protective film 20a on the protective film assembly 20 is fixed in a fixed position on the peeling platform 412, thereby ensuring that the position of each individual protective film 20a on the product is accurate.

[0049] like Figure 4 As shown, in one embodiment, the roller structure 320 includes a first roller assembly 321, a second roller assembly 322, and a recovery roller assembly 323 sequentially connected to the support frame 500. The recovery roller assembly 323 is disposed below the flattening structure 330. One end of the first roller assembly 321, the second roller assembly 322, and the recovery roller assembly 323 are all connected to the output end of a drive motor. The drive motor can drive the first roller assembly 321, the second roller assembly 322, and the recovery roller assembly 323 to rotate relative to the support frame 500, so that the roller structure 320 controls the movement of the protective film assembly 20. In this embodiment, the recycling roller assembly 323 is also provided with a tie rod, and the material strip 20b at the end of the protective film group 20 can be tied to the tie rod, so that the recycling roller assembly 323 can easily rotate and wind the recycling material strip 20b. The first roller assembly 321, the second roller assembly 322 and the recycling roller assembly 323 are driven to rotate by the drive motor, so that the protective film group 20 passes through the first roller assembly 321, the flattening structure 330, the second roller assembly 322 and the pressing structure 340 in sequence, and finally enters the recycling roller assembly 323 to recycle the material strip 20b of the protective film group 20. The position of the protective film group 20 can be precisely controlled by controlling the drive motor.

[0050] like Figure 4 and Figure 9As shown, in one embodiment, the first roller assembly 321 includes a first roller body 3211 and a first adjusting block 3212. The first roller body 3211 is connected to the support frame 500, and the first adjusting block 3212 is slidably sleeved on the first roller body 3211. The second roller assembly 322 includes a second roller body 3221 and a second adjusting block 3222. The second roller body 3221 is connected to the support frame 500, and the second adjusting block 3222 is slidably sleeved on the second roller body 3221. In this embodiment, when applying protective film sets 20 of different widths, the position of the first adjusting block 3212 on the first roller body 3211 is adjusted so that the first roller body 3211 and the first adjusting block 3212 form a first groove adapted to the width of the protective film set 20. The position of the second adjusting block 3222 on the second roller body 3221 is adjusted so that the second roller body 3221 and the second adjusting block 3222 form a second groove adapted to the width of the protective film set 20. This limits the protective film set 20 within the first and second grooves, thereby reducing the shaking of the protective film set 20.

[0051] like Figure 9 As shown, in one embodiment, the roller structure 320 further includes a third roller assembly 323, a fourth roller assembly 324, and a fifth roller assembly 325. The third roller assembly 323 is connected to the stripping platform 412 and is located below the pressing structure 340 adjacent to the stripping platform 412. The fourth roller assembly 324 is connected to the support frame 500 and is located below the mounting arm structure 420 adjacent to the stripping platform 412. The fifth roller assembly 325 is connected to the support frame 500 and is located below the vacuum suction member 331. In this embodiment, the recycling roller assembly 323 is located below the feeding structure 310. After passing through the peeling platform 412, the protective film assembly 20 passes through the third roller assembly 323, the fourth roller assembly 324 and the fifth roller assembly 325 in sequence for tensioning and guidance. Finally, the material strip 20b that has separated from the single protective film 20a is guided from below the peeling platform 412 to the recycling roller assembly 323 for recycling. This ensures that the material strip 20b does not obstruct the film application process during recycling, and facilitates the replacement of the protective film assembly 20 and the recycled material strip 20b on the same side.

[0052] like Figure 4As shown, in one embodiment, the clamping structure 340 includes a clamping plate 341, a width adjusting block 342, and a clamping cylinder 343. The clamping cylinder 343 is connected to the support frame 500 and its output end is connected to the clamping cylinder 343. The clamping cylinder 343 is used to control the clamping plate 341 to slide up and down. The clamping plate 341 has an adjusting block groove 3401, and the width adjusting block 342 is installed in the adjusting block groove 3401. In this embodiment, the clamping plate 341 slides relative to the clamping cylinder 343 in a direction parallel to the Z-axis. The number of width adjusting blocks 342 is at least two, and two adjacent width adjusting blocks 342 are installed at intervals in the adjusting block groove 3401. The pressing cylinder 343 has two pressing control air holes. By supplying air to the two pressing control air holes of the pressing cylinder 343, the pressing plate 341 can be driven to rise and fall, so that the width adjustment block 342 of the pressing plate 341 presses against both sides of the protective film assembly 20, so that the protective film assembly 20 is tightly attached to the suction flattening structure 330 and the peeling table assembly 410 respectively. By sliding and adjusting the width between the two width adjustment blocks 342, the width of different protective film assemblies 20 can be adapted, thereby adapting to the film application of different specifications of protective film assemblies 20. Specifically, the adjustment block groove 3401 has a dovetail groove structure, so that the width adjustment block 342 can be smoothly slidably connected in the adjustment block groove 3401. Two adjacent width adjustment blocks 342 are installed at intervals in the adjustment block groove 3401 along a direction parallel to the Y-axis.

[0053] It is understood that the number of width adjusting blocks 342 can be two, three, or other numbers, and can be flexibly set according to actual needs. Furthermore, the position of the width adjusting blocks 342 installed in the adjusting block groove 3401 is adjustable, so that two of the width adjusting blocks 342 can better protect the two sides of the membrane assembly 20 and perform a pressing effect. In this embodiment, the pressing structure 340 further includes at least two tightening members. The pressing plate 341 has screw holes 3402 communicating with the adjusting block slide groove 3401. The number of screw holes 3402 is at least two. Two adjacent screw holes 3402 are spaced apart along the extension direction of the adjusting block slide groove 3401. Each tightening member passes through the corresponding screw hole 3402 and abuts against the width adjusting block 342. When it is necessary to adjust the installation position of each width adjusting block 342 relative to the adjusting block slide groove 3401, the tightening member is loosened, the installation position of the width adjusting block 342 relative to the adjusting block slide groove 3401 is adjusted, and then the tightening member is tightened. This improves the adaptability of the pressing structure 340 to protective film assemblies 20 of different sizes.

[0054] like Figure 2 and Figure 4As shown, in one embodiment, the mounting arm structure 420 includes a guide rail assembly 421, a suction head assembly 422, and a guide rail cylinder 423. The guide rail assembly 421 is fixed to the support frame 500. The suction head assembly 422 is slidably connected to the guide rail assembly 421. The suction head assembly 422 is also connected to the output end of the guide rail cylinder 423, which is used to control the sliding of the suction head assembly 422. In this embodiment, the suction head assembly 422 slides relative to the guide rail assembly 422 in a direction parallel to the Z-axis. The guide rail cylinder 423 controls the suction head assembly to slide up and down on the guide rail assembly 421, thereby controlling the suction head assembly 422 to pick up the single protective film 20a and attach it to the product. The guide rail cylinder 423 adjusts the pressing height so that the suction head assembly 422 can adapt to attach the single protective film 20a to the product surface at different heights.

[0055] like Figure 2 and Figure 4 As shown, in one embodiment, the suction head assembly 422 includes a pressing member 4221, a first auxiliary material suction head 4222, a second auxiliary material suction head 4223, a cylinder slide 4224, and a sliding cylinder 4225. The pressing member 4221 is slidably connected to the guide rail assembly 421. The first auxiliary material suction head 4222 and the cylinder slide 4224 are both connected to one end of the pressing member 4221. The second auxiliary material suction head 4223 is slidably connected to the cylinder slide 4224. The cylinder slide 4224 is connected to the output end of the sliding cylinder 4224 and is used to control the sliding of the second auxiliary material suction head 4223. In this embodiment, the pressing member 4221 slides relative to the guide rail assembly 421 in a direction parallel to the Z-axis, and the second auxiliary material suction head 4222 slides relative to the pressing member 4221 in a direction parallel to the Y-axis. The first auxiliary material suction head 4222 is also provided with a first air inlet, which is connected to the output end of a first suction pump. The first suction pump is used to control the first auxiliary material suction head 4222 to pick up and release the monomer protective film 20a. The second auxiliary material suction head 4223 is also provided with a second air inlet, which is connected to the output end of a second suction pump. The second suction pump is used to control the second auxiliary material suction head 4223 to pick up and release the monomer protective film 20a. Two parallel rows can be arranged on the protective film assembly 20. Multiple individual protective films 20a can be simultaneously picked up by the first auxiliary material suction head 4222 and the second auxiliary material suction head 4223 for film application, which increases the film application efficiency of the adhesive mechanism 400. The cylinder slide 4224 can control the position of the second auxiliary material suction head 4223, so that the first auxiliary material suction head 4222 and the second auxiliary material suction head 4223 can be spaced at different distances, thereby adapting to different specifications of individual protective films 20a for assembly.

[0056] like Figure 4 and Figure 9As shown, in one embodiment, the feeding structure 310 includes a support arm 311, a blocking member 312, a connecting rod 313, and an adjustment assembly 314. There are two blocking members 312. The support arm 311 is connected to the support frame 500, the connecting rod 313 is connected to the support arm 311, and the connecting rod passes through the blocking member 312 and the fixing member 315. In this embodiment, the adjustment component 314 also includes a fixing member 3141 and a locking member 3142. The fixing member 3141 has a fixing hole 3101, and the locking member 3142 passes through the fixing hole 3101. By loosening the locking member 3142, the fixing member 3141 and the blocking member 312 can be removed to replace the protective film assembly 20. By setting the blocking member 312 and the fixing member 3141 at different positions on the connecting rod 313, protective film assemblies 20 of different widths can be adapted. The blocking member 312 can block the protective film assembly 20, thereby preventing the protective film assembly 20 from coming off and getting tangled when it becomes loose.

[0057] like Figure 10 As shown, this application also provides an automatic sprue cutting and film application integrated machine 10, including a sprue cutting device 10b, a conveying device 10c, and a film application device 10a as described in any of the above embodiments. The sprue cutting device 10b and the conveying device 10c are both installed on the workbench 100. The two ends of the conveying device 10c are respectively adjacent to the sprue cutting device 10b and the film application device 10a. The sprue cutting device 10b is used to cut the product sprue, and the conveying device 10c is used to grip and move the fixture 600 containing the product. In this embodiment, the conveying device 10c includes a guide rail mechanism 700a, a gripping mechanism 700b, and a conveyor belt mechanism 700c. The guide rail mechanism 700a is connected to the worktable 100. The cutting nozzle device 10b is disposed at one end of the guide rail mechanism 700a. The base adjustment mechanism 200 and the mounting boss 110 are adjacent to the middle of the guide rail mechanism 700a. The gripping mechanism 700b is slidably disposed on the guide rail mechanism 700a. The conveyor belt mechanism 700c is connected to the worktable 100 and disposed at the other end of the guide rail mechanism 700a. Further, the cutting nozzle device 10b includes a sliding mechanism 800a, a cutting mechanism 800b, and a cutting nozzle body 800c. The sliding mechanism 800a is disposed inside the cutting nozzle body 800c, and the cutting mechanism 800b is connected to the cutting nozzle body 800c. The sliding structure can slidably extend out of the cutting nozzle body 800c and approach the guide rail mechanism 700a.

[0058] Furthermore, the product is installed in a fixture, and the cutting nozzle device 10b can cut the product installed in different fixtures. During processing, the gripping mechanism 700b grips the fixture 600 containing the product from the guide rail mechanism 700a, and transfers the fixture 600 containing the product to the sliding mechanism 800a. The sliding mechanism 800a brings the fixture 600 containing the product under the cutting mechanism 800b for cutting. After cutting, the fixture containing the product is brought out by the sliding mechanism 800a and close to the gripping mechanism 700b. The gripping mechanism 700b then... The new product-loaded fixture 600 is gripped by the gripping mechanism 700b, which then moves closer to the film-applying device 10a via the guide rail mechanism 700a. The gripping mechanism 700b places the product-loaded fixture on the mounting boss 110, and the film-applying device 10a applies the film. After film application, the gripping mechanism 700b grips the product-loaded fixture 600 again, moves closer to the conveyor belt mechanism 700c via the guide rail mechanism 700a, and places the product-loaded fixture on the conveyor belt mechanism 700c for transport. The controllable cutting mechanism 800b can cut products on different fixtures, and the film-applying device 10a can apply film with high precision to products of different specifications. This allows the automatic sprue cutting and film-applying integrated machine to perform automatic sprue cutting and film-applying production line processing for products of different specifications, improving the versatility and production efficiency of the automatic sprue cutting and film-applying integrated machine.

[0059] Compared with the prior art, the present invention has at least the following advantages:

[0060] The aforementioned automatic film applicator 10a and automatic sprue cutting and film applicator 10, in which multiple individual protective films 20a are adhered to the protective module on the material belt 20b and matched with the fixture 600 for film application, saves the process of cutting the protective film group 20 by applying the individual protective films 20a, thereby improving production efficiency.

[0061] The position of the protective film assembly 20 can be adjusted in real time by the tensioning of the roller structure 320. The protective film assembly 20 is adsorbed by the suction structure 330, so that the individual protective films 20a on the protective film assembly 20 are spread out on the surface of the suction structure 330, thereby avoiding wrinkles in the protective film assembly 20 during film application and improving the quality of film application. The protective film assembly 20 is pressed by the pressing structure 340, so that the protective film assembly 20 is taut and adheres to the peeling table assembly 410, so that the protective film assembly 20 is laid flat in a fixed position on the peeling table assembly 410, thereby ensuring that the mounting arm structure 420 accurately picks up the individual protective films 20a on the protective film assembly 20 and accurately installs the individual protective films 20a on the product surface.

[0062] Different specifications of protective film assemblies 20 can be installed on the feeding structure 310. The roller structure 320, the suction structure 330 and the pressing structure 340 can be adapted to adjust the position of the protective film assembly 20 on the peeling table assembly 410. The base adjustment mechanism 200 can precisely adjust the position of the product and the mounting arm structure 420 according to different specifications of products, so that the automatic film applicator 10a has high film applicability and compatibility.

[0063] The sprue cutting device 10b can be adapted to cut sprues for different products, and the film application device 10a can apply film to products of different specifications with high precision. This makes the automatic sprue cutting and film application integrated machine 10 compatible with products of different specifications for automatic sprue cutting and film application in a production line, improving the versatility and production efficiency of the automatic sprue cutting and film application integrated machine 10.

[0064] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
