Description

Technical Field

[0001] This application relates to the field of heat dissipation cotton supply technology, and in particular to a supply device, control method and system. Background Technology

[0002] In related technologies, circuit boards are indispensable components in electronic devices. Whether it's large machinery, personal computers, mobile phones, or home appliances, circuit boards are used as the core for control. During operation, circuit boards often generate a significant amount of heat, requiring timely dissipation to keep their operating temperature within a reasonable range. Using thermal pads is a highly effective method for heat dissipation of circuit boards.

[0003] Currently, thermal pads are pre-applied with protective films before installation and use, which must be removed. Currently, the films are typically removed manually by workers. This method is labor-intensive and inefficient; furthermore, manually removing the films easily contaminates the surface of the thermal pads, hindering subsequent processing. Therefore, improving the efficiency of film removal while ensuring the cleanliness of the thermal pad surface has become a pressing technical problem. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a feeding device, control method, and system that can improve the film-tearing efficiency of heat dissipation cotton and ensure the cleanliness of the heat dissipation cotton surface.

[0007] A material-grabbing component is disposed on one side of the material-feeding component. The material-grabbing component is used to pick up the heat dissipation cotton and transport it to the discharge position.

[0008] A film-tearing mechanism is disposed on one side of the material-taking component. The film-tearing mechanism includes a film-pressing component, a film-suction component, and a film-clamping component.

The entire film-tearing operation does not require manual intervention, and the efficiency of film-tearing operation can be effectively improved through the cooperation of various structural components; on the other hand, the absence of manual film tearing avoids direct contact with the heat dissipation cotton, thereby effectively preventing the surface of the heat dissipation cotton from being contaminated by various stains, and thus ensuring the cleanliness of the surface of the heat dissipation cotton.

[0061] Below, according to Figures 1 to 12 This application describes a feeding device according to an embodiment.

[0062] It is understandable that, such as Figure 1 and Figure 5 As shown, a feeding device is provided, comprising:

[0063] Feeding assembly 100 is used to provide heat dissipation cotton;

[0064] The material handling component 200 is located on one side of the material feeding component 100. The material handling component 200 is used to pick up the heat dissipation cotton and transport it to the discharge position.

[0065] The film-tearing mechanism 300 is located on one side of the material-taking component 200. The film-tearing mechanism 300 includes a film-pressing component 310, a film-suction component 320, and a film-clamping component 330. The film-pressing component 310 is used to press down the heat dissipation cotton on the material-discharging position, the film-suction component 320 is used to suck up the upper film sheet of the heat dissipation cotton, and the film-clamping component 330 is used to clamp the sucked upper film sheet and tear the film.

[0066] The film-removing mechanism 400 is used to remove the lower film sheet of the heat dissipation cotton. The film-removing mechanism 400 removes the film simultaneously with the film-clamping assembly 330.

[0067] By setting up a feeding component 100, a picking component 200, a film-tearing mechanism 300, and a film-removing mechanism 400, and the film-tearing mechanism 300 includes a film-pressing component 310, a film-suction component 320, and a film-clamping component 330; when tearing the film of the heat dissipation cotton, on the one hand, the heat dissipation cotton 500 is first provided by the feeding component 100, then the heat dissipation cotton 500 is picked up by the picking component 200 and placed on the picking plate 410 at the material dispensing position. Then, the heat dissipation cotton 500 is pressed by the film-pressing component 310, picked up by the film-suction component 320, and the film-clamping component 330 clamps the picked-up film and tears the film. At the same time as the film-clamping component 330 tears the film, the film-removing mechanism 400 tears off the lower film of the heat dissipation cotton 500. The peeled heat dissipation cotton 500 is peeled off to the picking plate 410 at the material dispensing position. The entire film-removing process requires no manual intervention. Through the coordinated operation of various structural components, the efficiency of the film-removing process is effectively improved. Furthermore, the elimination of manual film removal avoids direct contact with the heat dissipation cotton 500, thus effectively preventing contamination of its surface and ensuring its cleanliness. Therefore, the feeding device of this application can improve the film-removing efficiency of the heat dissipation cotton 500 and ensure the cleanliness of its surface.

[0068] In some embodiments, such as Figure 1 As shown, the film-peeling mechanism 300 is mounted on the material-taking assembly 200.

[0069] It is understandable that, such as Figure 2As shown, the feeding assembly 100 includes a loading platform 110, a material presence sensor 120, a material arrival sensor 130, a synchronous pulley 140, and a lifting motor 150. The material presence sensor 120 is located below the loading platform 110, and the material arrival sensor 130 is located above the loading platform 110. The synchronous pulley 140 and the lifting motor 150 are connected by a synchronous belt drive. The loading platform 110 is used to place the heat dissipation cotton 500. The material presence sensor 120 is used to sense whether the loading platform 110 has heat dissipation cotton 500. The lifting motor 150 is used to drive the synchronous pulley 140 when the material presence sensor 120 senses the heat dissipation cotton 500. The synchronous pulley 140 is used to lift the heat dissipation cotton 500 to the sensing position of the material arrival sensor 130.

[0070] It should be noted that the heat dissipation cotton 500 is manually placed on the material carrier platform 110. After the material sensor 120 under the material carrier platform 110 detects the presence of material, the lifting motor 150 drives the synchronous belt of the synchronous pulley 140 to lift the heat dissipation cotton 500 to the sensing position of the material arrival sensor 130. After the material arrival sensor 130 detects the presence of material, the material picking component 200 picks up the material. Through the cooperation of the material carrier platform 110, the material sensor 120, the material arrival sensor 130, the synchronous pulley 140 and the lifting motor 150, automatic feeding is achieved, which is convenient and fast.

[0071] It should be noted that the loading platform 110 is compatible with 1mm-5mm thick heat dissipation cotton 500, in quantities of 20 to 100 pieces.

[0072] It should be noted that multiple heat dissipation foams 500 can share one upper film, and multiple heat dissipation foams 500 can share one lower film.

[0073] It is understandable that, such as Figure 1 , Figure 3 and Figure 4 As shown, the material handling assembly 200 includes a material handling suction plate 210 and a drive assembly 220. The material handling suction plate 210 is disposed above the material carrier platform 110. The drive assembly 220 is connected to the material handling suction plate 210. The drive assembly 220 is used to drive the material handling suction plate 210 to pick up the heat dissipation cotton 500 at the sensing position and place the heat dissipation cotton 500 at the material placement position.

[0074] It is understandable that, such as Figure 4As shown, the drive assembly 220 includes a material handling motor 221, a material handling cylinder 222, a slide rail slider 223, and a connecting plate 224. The material handling motor 221 is located on one side below the film-peeling mechanism 300. The drive end of the material handling motor 221 is connected to the material handling cylinder 222. The material handling cylinder 222 is located on the slide rail slider 223. The slide rail slider 223 is arranged along the route from the material loading platform 110 to the material handling position. One end of the connecting plate 224 is connected to the drive end of the material handling cylinder 222, and the other end of the connecting plate 224 is connected to the material handling suction plate 210. The material handling cylinder 222 is used to drive the material handling suction plate 210 to move vertically, and the material handling motor 221 is used to drive the material handling cylinder 222 to move horizontally on the slide rail slider 223, so as to drive the material handling suction plate 210 to move horizontally.

[0075] The drive end of the pick-and-place motor 221 drives the pick-and-place cylinder 222 to move horizontally on the slide rail slider 223 via a synchronous belt pulley.

[0076] It should be noted that after the material arrival sensor 130 in the feeding assembly 100 senses the material, the pick-up and release motor 221 drives the pick-up suction plate 210 to the pick-up position. The pick-up and release cylinder 222 descends and drives the pick-up suction plate 210 to pick up the heat dissipation cotton. After the pick-up and release cylinder 222 rises, the pick-up and release motor 221 transports the heat dissipation cotton to the release position. The release position is correspondingly set with a release position. The heat dissipation cotton is peeled off and picked up at the release position.

[0077] The automatic material handling is achieved through the cooperation of the material suction plate 210, the material handling motor 221, the material handling cylinder 222, the slide rail slider 223 and the connecting plate 224, which is convenient and fast, and further improves the film tearing efficiency.

[0078] It is understandable that, such as Figure 5 , Figure 6 and Figure 7 As shown, the film pressing assembly 310 includes a film pressing cylinder 311, a first connecting block 312, an upper film peeling blade 313, a buffer spring 314, and a film pressing roller 315. The film pressing cylinder 311 and the first connecting block 312 are movably connected. A buffer spring 314 is provided between the film pressing roller 315 and the first connecting block 312. The upper film peeling blade 313 is arranged parallel to the film pressing roller 315 and is connected to the first connecting block 312. The film pressing cylinder 311 is used to drive the upper film peeling blade 313 and the film pressing roller 315 to descend. The film pressing roller 315 is used to press the heat dissipation cotton. The buffer spring 314 is used to mitigate the downward pressure of the film pressing roller 315. The upper film peeling blade 313 is used to peel the upper film off the heat dissipation cotton.

[0079] It should be noted that the pressure cylinder 311 drives the upper film-peeling blade 313 and the pressure roller 315 to descend and press the heat dissipation cotton. The pressure roller 315 rolls in close contact with the heat dissipation cotton. At the same time, the pressure roller 315 is equipped with a buffer spring 314 to prevent the heat dissipation cotton from being crushed during film peeling, thus preventing the film from becoming impossible to peel, and also to prevent the heat dissipation cotton from shifting as a whole during film peeling, thereby messing up the heat dissipation cotton. In particular, during film peeling, the upper film-peeling blade 313 is positioned diagonally above the pressure roller 315 to facilitate the detachment of the upper film sheet.

[0080] It is understandable that, such as Figure 8 As shown, the suction film assembly 320 includes a lifting motor 321, a second connecting block 322, and a suction cup 323. The drive rod of the lifting motor 321 is connected to the second connecting block 322. The suction cup 323 is located on the other side of the second connecting block 322 opposite to the lifting motor 321. The lifting motor 321 is used to drive the suction cup 323 to descend so that the suction cup 323 can pick up the film.

[0081] It should be noted that the suction film assembly 320 also includes a first guide rod 324 and a first guide block 325. The first guide block 325 is fixedly installed, and the first guide rod 324 passes through the first guide block 325. One end of the first guide rod 324 is connected to one side of the second connecting block 322. The lifting motor 321 and the first guide rod 324 are arranged in parallel on the same side of the second connecting block 322. The first guide rod 324 is used to guide the driving direction of the lifting motor 321.

[0082] It should be noted that the film suction assembly 320 also includes a fourth connecting block 326 and an origin sensor 327. The fourth connecting block 326 is connected to the first guide block 325, and the origin sensor 327 is disposed on the fourth connecting block 326, and the origin sensor 327 and the fourth connecting block 326 are movably connected. The fourth connecting block 326 and the origin sensor 327 are used to control the stroke of the lifting motor 321. By setting the fourth connecting block 326 and the origin sensor 327, precise control of the stroke of the lifting motor 321 is achieved, thereby improving the accuracy of film tearing.

[0083] It should be noted that the lifting motor 321 controls the suction cup 323 to lift and pick up the upper film of the heat dissipation cotton, so that the upper film and the heat dissipation cotton are separated. In particular, the lifting motor 321 is a stepper screw motor, which can precisely control the film tearing height.

[0084] It should be noted that the first guide rod 324 is the air passage for the suction cup 323, combining air passage and guidance to save space.

[0085] It is understandable that, such as Figure 9 and Figure 10As shown, the film clamping assembly 330 includes a guide reset assembly 331, a third connecting block 332, a film clamping hand 333, a main body plate 334, a pusher rod 335, and a film clamping air inlet 336. The main body plate 334 is provided with an air chamber. One end of the pusher rod 335 is movably disposed in the air chamber. The film clamping air inlet 336 is connected to the air chamber. The other end of the pusher rod 335 is connected to the third connecting block 332. One side of the guide reset assembly 331 is connected to one side of the third connecting block 332, and the other side of the guide reset assembly 331 is connected to the main body plate 334. The film clamping air inlet 336 is used to introduce air pressure into the air chamber to push the pusher rod 335, so that the film clamping hand 333 clamps the film sheet separated from the film clamping assembly 320 and performs film tearing.

[0086] It should be noted that air pressure enters the air chamber of the main body plate 334 through the membrane clamping air inlet 336, thereby pushing the pusher rod 335 and pushing the upper membrane clamp 333 to clamp the upper membrane sheet separated from the membrane suction assembly 320, and then tearing the film. By combining the air chamber and the pusher rod 335, they can be integrated into the main body plate 334 as a single cylinder, thus saving space.

[0087] It should be noted that the clamping membrane assembly 330 also includes a reset spring, a second guide rod 3311, and a second guide block 3312. One end of the second guide rod 3311 is connected to one side of the third connecting block 332, and the second guide rod 3311 and the push rod 335 are arranged in parallel. The second guide block 3312 is fixedly mounted on the main body plate 334, and the second guide rod 3311 passes through the second guide block 3312. The reset spring is mounted on the second guide rod 3311, and one end of the reset spring abuts against the other end of the second guide rod 3311. The other end of the reset spring abuts against the side of the second guide block 3312.

[0088] It is understandable that, such as Figure 11 As shown, the film-peeling mechanism 400 includes a material-taking plate 410, a lifting cylinder 420, a bottom film peeling blade 430, and a bottom film clamping assembly 440. The bottom film peeling blade 430 is disposed on one side of the material-taking plate 410. The drive rod of the lifting cylinder 420 is connected to the material-taking plate 410. The bottom film clamping assembly 440 is disposed below the bottom film peeling blade 430. The lower film sheet of the heat dissipation cotton includes a blank sheet. The lifting cylinder 420 is used to lift the material-taking plate 410 so that the material-taking assembly 200 places the blank sheet between the material-taking plate 410 and the bottom film peeling blade 430. The lifting cylinder 420 is also used to press down the material-taking plate 410 to drive the blank sheet to press down. The bottom film clamping assembly 440 is used to clamp the pressed blank sheet to peel off the lower film sheet.

[0089] It should be noted that the material pick-up plate 410 is located at the material dispensing position, so that the heat dissipation cotton 500 falls onto the material pick-up plate 410 after the film is torn off.

[0090] It is understandable that, such as Figure 12 As shown, the clamping film assembly 440 includes a clamping cylinder 441, a clamping film plate 442, a clamping film claw 443, and a transmission assembly 444. The clamping cylinder 441 is mounted on the transmission assembly 444, and the clamping film plate 442 is mounted on one side of the clamping cylinder 441. The clamping film claw 443 is connected to the drive rod of the clamping cylinder 441. The transmission assembly 444 is used to drive the clamping cylinder 441 to move to the position of the blank sheet. The clamping cylinder 441 is used to drive the clamping film claw 443 to approach the clamping film plate 442 to clamp the blank sheet.

[0091] It should be noted that the lifting cylinder 420 lifts the material taking plate 410, the material taking component 200 sends the blank sheet of the lower film into the space between the material taking plate 410 and the bottom film peeling knife 430, the lifting cylinder 420 descends, causing the material taking plate 410 to press the blank sheet of the lower film downwards, the transmission component 444 sends the bottom film clamping component 440 to below the bottom film peeling knife 430, the clamping cylinder 441 moves to drive the bottom film clamping claw 443 to clamp the blank sheet, and the transmission component 444 moves to tear the blank sheet of the bottom film.

[0092] By combining the material feeding plate 410 and the bottom film peeling knife 430, the demand for blank sheets can be reduced, thereby reducing the length requirement of the bottom film and saving materials.

[0093] It should be noted that the film-peeling mechanism 400 also includes a bottom film suction plate 450 and a bottom film blowing workpiece 460. The bottom film suction plate 450 is located on one side of the bottom film peeling knife 430. The material taking plate 410, the bottom film peeling knife 430 and the bottom film suction plate 450 form a material feeding position. The bottom film suction plate 450 is used to temporarily absorb the heat dissipation cotton with the lower film sheet. The bottom film blowing workpiece 460 is located at one end of the bottom film suction plate 450 and is used to blow the peeled lower film sheet.

[0094] It should be noted that the transmission component 444 uses a large and small gear conversion to increase torque.

[0095] It should be noted that the film is peeled off at a low angle, which reduces the material removal height and saves space.

[0104] The heat dissipation cotton on the feeding position is pressed by the pressing film assembly 310, and the upper film of the heat dissipation cotton is picked up by the suction film assembly 320.
