Description

Technical Field

[0001] This invention relates to the field of Mylar application equipment technology, specifically to a general-purpose automatic Mylar application machine. Background Technology

[0002] The current industry standard for Mylar application is as follows: First, place the product into the fixture, then tear off the special Mylar protective film. Fix one side of the round hole to the fixture positioning pin, tear off the protective film and stick it on the product, then align the other side of the round hole with the fixture positioning pin, press the Mylar flat by hand, and finally peel off the top protective film to complete the Mylar application.

[0003] Due to the diversity of product structures, the industry has not yet achieved universality in automatic Mylar application. The existing Mylar application technology in the industry involves customizing Mylar to a specific length and size according to the product and manually applying it to the product. This is extremely inefficient and labor-intensive. In addition, the Mylar is prone to sticking together, making the operation difficult. Summary of the Invention

[0053] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0054] See Figures 1-15 This embodiment discloses a general-purpose automatic Mylar applicator, including a frame 1, a Mylar feeding assembly 2, a guide wheel assembly 3, a Mylar flow channel assembly 4, a Mylar applicator 5, a cutting assembly 6, a pulling assembly 7, and a support seat 8 mounted on the frame 1. The support seat 8 is located below the Mylar applicator 5, and the cutting assembly 6 is located on the side of the Mylar flow channel assembly 4.

[0055] Mylar feeding assembly 2 is used for feeding Mylar wound into a disc shape;

[0056] The guide wheel assembly 3 is configured to change the direction of Myra's movement;

[0057] Mylar flow channel assembly 4 is used to guide the Mylar;

[0058] Pull component 7 is used to pull Mylar to move and position Mylar below Mylar attachment component 5;

[0059] The Mylar attachment component 5 is used to fix the Mylar after it is adsorbed by negative pressure, and after the Mylar is cut by the cutting component 6, it is attached to the workpiece fixed on the support seat 8.

[0060] Cutting component 6 is used to cut the Mylar;

[0061] The support 8 is used to place the workpiece so that the Mylar assembly 5 can correctly attach the Mylar to the workpiece.

[0062] To facilitate a better understanding of the invention by those skilled in the art, the structure of each component in this invention will be further described below.

[0063] Mylar feeding assembly 2 is mainly used to install Mylar roll material, and it can be made using the existing material conveying mechanism, which will not be described in detail in this application.

[0064] The guide wheel assembly 3 includes a first guide wheel assembly 3001 and a second guide wheel assembly 3002. Both the first guide wheel assembly 3001 and the second guide wheel assembly 3002 include a guide roller with a guide groove. The guide roller is rotatably mounted on the frame 1. After the Mylar is drawn out from the reel, the non-adhesive side of the Mylar is wrapped around the guide roller to guide the Mylar.

[0065] The specific structure of Mylar flow channel assembly 4 is as follows:

[0066] Mylar flow channel assembly 4 includes a mounting base 101, on which a groove 102 is provided. An adjusting block 103 is slidably disposed in the groove 102. The adjusting block 103 is fixed in position by a locking assembly. A Mylar flow channel is formed between the side of the adjusting block 103 and the groove 102.

[0067] The mounting base 101 is slidably provided with a bracket 104. The bracket 104 passes through the mounting base 101 and is connected to a guide wheel 105. The guide wheel 105 is located below the Mylar channel. A reset component 106 is provided between the mounting base 101 and the bracket 104. The reset component 106 is used to drive the guide wheel 105 to contact the adhesive surface of the Mylar, so that the Mylar and the Mylar channel fit together.

[0068] A support assembly 107 is provided at the outlet position of the Mylar channel. The support assembly 107 is used to press the Mylar into the Mylar channel. The support assembly 107 is connected to the bracket 104.

[0069] In practical use, the width of the Mylar channel can be adjusted according to the Mylar model. Since one side of the Mylar is adhesive, the guide wheel 105 contacts this adhesive side, allowing the Mylar to move freely within the Mylar channel. The reset component 106 ensures that the guide wheel 105 and support component 107 contact the Mylar, and the support component 107 supports the Mylar at the outlet position of the Mylar channel, facilitating cutting by the cutting component 6. During automated Mylar application, the channel width can be adjusted according to the Mylar specifications to meet the needs of Mylars of different widths, improving the versatility of the device.

[0070] The locking assembly includes a strip groove 108 on the adjusting block 103, a hole on the mounting base 101, and a bolt. The bolt passes through the strip groove 108 and the hole and is connected to a wing nut. This arrangement allows the position of the adjusting block 103 to be adjusted according to the width of the Myra, and the adjusting block 103 is fixed by the bolt and the wing nut.

[0071] Alternatively, the locking assembly includes an L-shaped connecting plate and a screw mounted on the mounting base 101. The L-shaped connecting plate is threaded to the screw, and the end of the screw is rotatably connected to the adjusting block 103.

[0072] In practice, the screw and the adjusting block 103 are rotatably connected by bearings. In order to make the adjusting block 103 more stable when moving, in actual use, the adjusting block 103 is slidably installed on the mounting base 101 in the form of a dovetail groove.

[0073] When the width of the Mylar channel needs to be adjusted, simply turn the screw; the adjustment process is more convenient and faster.

[0074] Furthermore, a handwheel is provided on the screw.

[0075] The bracket 104 includes a connecting part 110 and vertical parts 109 disposed on both sides of the connecting part 110. The vertical parts 109 pass through the mounting base 101 and are slidably connected to the mounting base 101. One vertical part 109 is connected to the guide wheel 105, and the other vertical part 109 is connected to the support assembly 107.

[0076] Furthermore, the support assembly 107 includes a connecting block 112 and at least one first guide wheel 111 disposed on the connecting block 112. The connecting block 112 is fixedly connected to the bracket 104, and a support portion 113 extending into the Mylar channel is disposed on the connecting block 112.

[0077] Furthermore, at least one rib 114 is provided on the support portion 113, the rib 114 being used to contact the Mylar adhesive surface.

[0078] The first guide wheel 111 is used to press the Mylar into the Mylar channel, while the ribs 114 reduce the contact area with the Mylar adhesive surface, preventing the Mylar from sticking to the support 113 and being difficult to remove.

[0079] The reset assembly 106 includes at least one reset spring, with its upper end connected to the bracket 104 and its lower end connected to the mounting base 101.

[0080] In this embodiment, there are two return springs; the return springs ensure that the Mylar is positioned in the Mylar flow channel.

[0081] Both the bracket 104 and the mounting base 101 are provided with positioning holes, and the two ends of the reset spring are located inside the positioning holes.

[0082] Furthermore, both the mounting base 101 and the adjusting block 103 are provided with guide slopes 115, which can guide the Mylar and facilitate the Mylar entering the Mylar flow channel.

[0083] As an alternative, in actual use, the groove 102 is a stepped groove, and the adjusting block 103 is installed in the stepped groove, with the side of the Myra contacting the side of the adjusting block 103.

[0084] This prevents Mylar from entering the gap between the adjusting block 103 and the mounting base 101 during movement, which could cause Mylar to move uncontrollably.

[0085] Furthermore, in some preferred embodiments, a pressing cylinder 116 is connected above the support 104. When the pressing cylinder 116 extends, it can drive the support 104 to move, facilitating the replacement of the Mylar. At the same time, when the Mylar is being cut, the pressing cylinder 116 drives the support 104 to move upward, and the support part 113 presses the Mylar tightly into the Mylar flow channel, making it easier for the cutting assembly to cut the Mylar.

[0086] In actual use, the support base and the press cylinder 116 are installed on the frame 1.

[0087] The specific structure of the Mylar component 4 is as follows:

[0088] The Mylar applicator 4 includes a support frame 201, a drive mechanism 202, and a negative pressure adsorption component 203. The support frame 201 is slidably mounted on the frame 1 of the Mylar applicator. The drive mechanism 202 is connected to the support frame 201 and is used to drive the support frame 201 to move on the frame 1. The negative pressure adsorption component 203 is mounted on the support frame 201 and is used to adsorb the Mylar after it has been cut.

[0089] The negative pressure adsorption component 203 includes a negative pressure adsorption head 205 and a limiting block 206. The limiting block 206 has an installation groove 207. The negative pressure adsorption head 205 slides with the installation groove 207 and forms an adsorption area 208 at the end with the limiting block 206. A spring 213 is provided between the limiting block 206 and the negative pressure adsorption head. The limiting block 206 is provided with a groove 209 that communicates with the installation groove 207. The negative pressure adsorption head 205 is provided with a limiting post 210 that passes through the groove 209.

[0090] The negative pressure adsorption assembly 203 is used to adhere the cut Mylar to the workpiece. A drive mechanism 202 drives the negative pressure adsorption head 205 to move up and down, thus achieving the adsorption purpose. The negative pressure adsorption head 205 adsorbs the Mylar under negative pressure. Because a limiting block 206 is fitted over the negative pressure adsorption head 205, the Mylar is positioned within the adsorption area 208 after adsorption. During adsorption, the limiting block 206 aligns with the workpiece to which the Mylar is to be adhered. At this point, the limiting block 206 contacts and aligns with the workpiece. The negative pressure adsorption head 205 then moves, and under the action of the spring 213, the limiting block 206 remains stationary. After the negative pressure adsorption head 205 moves towards the workpiece, it adheres the Mylar to the workpiece. The limiting block 206 enables the positioning of the Mylar. The mounting groove 207 serves as a limiting guide, improving the adsorption accuracy of the Mylar.

[0091] Furthermore, the negative pressure adsorption head 205 has an overall T-shaped structure. Inside the negative pressure adsorption head 205 is a cavity 211, and several adsorption holes 212 communicating with the cavity 211 are provided at the end of the negative pressure adsorption head 205. The negative pressure head is connected to a negative pressure source. The negative pressure source can be a negative pressure pump or other negative pressure generating device. The several adsorption holes 212 can form multiple negative pressure adsorption points, improving the adsorption effect of Mylar.

[0092] The limiting block 206 and the negative pressure adsorption head 205 are provided with mounting holes at corresponding positions, and the two ends of the spring 213 are respectively located in the mounting holes.

[0093] Furthermore, in some specific implementation cases, the negative pressure adsorption head 205 is connected to the support frame 201 through the buffer mechanism 222.

[0094] The buffer mechanism 222 includes a movable plate 223, a U-shaped frame 224 and a buffer spring 214. The movable plate 223 is slidably installed inside the U-shaped frame 224. The two ends of the buffer spring 214 are respectively connected to the movable plate 223 and the U-shaped frame 224. The movable plate 223 is fixedly connected to the negative pressure adsorption head 205. The U-shaped frame 224 is fixedly installed on the support frame 201.

[0095] The buffer mechanism 222 serves as a buffer to prevent the negative pressure adsorption head 205 from colliding directly with the workpiece. The buffer spring 214 is compressed when the negative pressure adsorption head 205 contacts the workpiece. The negative pressure adsorption head 205 moves with the moving plate 223 and, during the continuous movement of the U-shaped frame 224, the negative pressure adsorption head 205 is pressed tightly against the workpiece, ensuring that the Mylar adheres firmly to the workpiece. This not only provides protection but also makes the Mylar bond more secure, preventing it from falling off.

[0096] In some embodiments, the U-shaped frame 224 is provided with an L-shaped limiting part for limiting the movement plate 223. The L-shaped limiting part can limit the movement plate 223 and prevent the return spring 213 from failing due to tension during the upward movement.

[0097] The drive mechanism 202 includes a turntable 215, a rocker arm 217 fixedly mounted on the turntable 215, and a motor 216 connected to the turntable 215 for driving the turntable 215 to rotate. The rocker arm 217 is provided with a strip-shaped clearance groove 218. A rotating wheel 219 is rotatably mounted on the support frame 201 via a rotating shaft. The rotating wheel 219 slides in cooperation with the strip-shaped clearance groove 218.

[0098] The turntable 215 can be driven to rotate by the motor 216, which in turn causes the rocker arm 217 to rotate, thereby achieving vertical drive of the support frame 201.

[0099] In practical applications, telescopic rods, such as pneumatic, hydraulic, or electric telescopic rods, can also be used to achieve vertical drive of the support frame 201.

[0100] The support frame 201 is slidably mounted on the frame 1 via the slider 220 and the slide rail 221.

[0101] In actual use, the movable plate 223 is also slidably mounted on the U-shaped frame 224 using a slider 220 and a slide rail 221.

[0102] The specific structure of the cutting component 6 is as follows:

[0103] The cutting assembly 6 includes a blade holder 601, a cutter 602, and a first drive unit 603. The blade holder 601 is slidably mounted on the frame 1, the cutter 602 is fixedly mounted on the blade holder 601, and the first drive unit 603 is mounted on the frame 1 and connected to the blade holder 601. The first drive unit 603 is used to drive the blade holder 601 to move, so that the cutter 602 can cut the Mylar after contacting it.

[0104] The specific structure of pull component 7 is as follows:

[0105] The device includes a first bracket 301 and a clamping mechanism 302. The first bracket 301 is used to be installed on the frame 1 of the Mylar applicator. The clamping mechanism 302 is slidably installed on the first bracket 301 and connected to a first drive mechanism 304. The first drive mechanism 304 is used to drive the clamping mechanism 302 to move on the first bracket 301.

[0106] The clamping mechanism 302 includes a fixed base 305, a sliding block 306, a first gripper 307, a second gripper 308, and a telescopic rod 309. The fixed base 305 and the telescopic rod 309 are fixedly mounted on the first drive mechanism 304 via a mounting plate 310. The fixed base 305 is provided with a first sliding groove 311 and a side groove 312, which are interconnected with the first sliding groove 311. The first gripper 307 and the second gripper 308 are slidably mounted in the side groove 312. The sliding block 306 is provided with a first inclined groove 313 and a second inclined groove 314, which are slidably mounted in the first sliding groove 311. The first gripper 307 and the second gripper 308 located in the side groove 312 are connected by a pin passing through the first inclined groove 313 and the second inclined groove 314. The telescopic rod 309 is connected to the sliding block 306 and is used to drive the sliding block 306 to move within the first sliding groove 311.

[0107] The pulling component 7 is mainly used to pull the Mylar. In use, the first driving mechanism 304 drives the clamping mechanism 302 to approach the Mylar, and drives the sliding block to move through the telescopic rod 309. During the movement of the sliding block, the first inclined groove 313 and the second inclined groove 314 are provided on the sliding block 306, which allows the pin to move in the first inclined groove 313 and the second inclined groove 314. Under the action of the first inclined groove 313 and the second inclined groove 314, the first gripper 307 and the second gripper 308 are driven to move, thus clamping and fixing the Mylar. At this time, the first driving mechanism 304 can drive the clamping mechanism 302 to move as a whole, according to the length of the Mylar required, to pull the Mylar. This facilitates the subsequent application of Mylar after the Mylar is adsorbed and fixed by the adhesive mechanism and then cut by the shearing mechanism.

[0108] The first gripper 307 and the second gripper 308 each have a gripping head 315. The gripping head 315 is provided with several toothed structures 316. The toothed structures 316 can clamp and fix the Myla more firmly, preventing slippage when pulling the Myla.

[0109] Furthermore, in some preferred embodiments, both the first inclined groove 313 and the second inclined groove 314 include an inclined portion 317 and a horizontally arranged flat portion 318, with the inclined portion 317 and the flat portion 318 connected.

[0110] This allows the first inclined groove 313 and the second inclined groove 314 to have a two-section structure. During the movement of the sliding block 306, when the pin on the first gripper 307 and the second gripper 308 is located in the inclined part 317, the first gripper 307 and the second gripper 308 will move closer to each other or further away from each other. When the sliding block 306 continues to move so that the pin is located in the flat part 318, the first gripper 307 and the second gripper 308 will remain stationary, thus achieving stable clamping of Myra.

[0111] The telescopic rod 309 can be pneumatic, hydraulic, or electric. In this embodiment, the telescopic rod 309 is preferably a pneumatic telescopic rod.

[0112] The first drive mechanism 304 includes a first slide rail 319 mounted on the first bracket 301 and a drive unit 320. A mounting plate 310 is slidably mounted on the first slide rail 319, and the drive unit 320 is mounted on the frame 1 and connected to the mounting plate 310. The drive unit 320 drives the mounting plate 310 to move stably, thereby driving the clamping mechanism 302, enabling the clamping mechanism 302 to move and pull the Mylar.

[0113] Among them, the drive unit 320 is a lead screw drive unit. In actual use, other drive units 320 can also be used, as long as they can achieve stable reciprocating movement of the clamping mechanism 302.

[0114] In some preferred embodiments, the second gripper 308 is provided with an air collection seat 321, which is hollow inside and connected to an air source. The second gripper 308 is provided with a flow channel 322 at the position where it grips Mylar, and the flow channel 322 is connected to the inside of the air collection seat 321.

[0115] Because the Mylar has an adhesive surface, the first gripper 307 and the second gripper 308 clamp and fix the Mylar. After being pulled, the adhesive surface of the Mylar does not easily fall off after contacting the second gripper 308. Therefore, the Mylar is blown by the set flow channel 322 and air source. The Mylar is detached from the second gripper 308 by using high pressure gas, so that the Mylar can be attached.

[0116] The support base 8 is mainly used to support and fix the workpiece. The support base 8 includes a base 801 and a second drive unit 802. The second drive unit 802 is used to drive the base 801 to move on the frame 1. After the workpiece is fixed on the base 801, the second drive unit 802 drives the base 801 to move the workpiece to the bottom of the Mylar assembly 5. Then the Mylar assembly 5 performs the Mylar application operation. After the Mylar application is completed, the second drive unit 802 drives the workpiece to reset so that a new workpiece to be applied Mylar can be placed.

[0117] In practical use, the steps for applying Mylar are as follows:

[0118] Step 1: Fix the workpiece to be covered with Mylar onto the carrier 8. The carrier 8 will then deliver the workpiece to the bottom of the Mylar application assembly 5.

[0119] Step 2: After the Mylar on the Mylar feeding assembly 2 passes around the guide wheel assembly 3, it passes through the Mylar flow channel assembly 4 to guide the Mylar;

[0120] Step 3: Pull component 7 to clamp and fix the Mylar extending from Mylar channel component 4, and then pull the Mylar to move it so that the Mylar is directly below the Mylar attachment component 5;

[0121] Step 4: Place the Mylar component 5 close to and in contact with the non-adhesive surface of the Mylar, and apply negative pressure to the Mylar to fix it in place;

[0122] Step 5: The cutting component 6 is brought close to the Myra and cuts the Myra to the required length;

[0123] Step 6: The Mylar assembly 5 delivers the Mylar that is adsorbed and fixed to the workpiece above it and drives the Mylar to contact the workpiece, thereby achieving the attachment of the workpiece.

[0124] This invention automatically cuts Mylar reels to the required length and then automatically applies them to products. This automated Mylar application process greatly improves production efficiency and quality, reduces labor costs, achieves universality for different Mylar lengths across various products, and solves the problem of Mylar adhesion, completely overcoming the bottleneck in Mylar application manufacturing and elevating the process to a new level. Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this invention.
