Description

Technical Field

[0001] The invention relates to the field of plastic injection molding, and in particular to a double-layer texture processing device and method. Background Art

[0002] As consumers become increasingly picky about the appearance and touch of products, the decorativeness and tactile experience of electronic product shells have become particularly important. The injection molding process has great limitations in achieving appearance texture effects or patterns. Traditional injection molding processes can often only achieve simple texture or pattern effects, but it is difficult to achieve design effects with a strong sense of three-dimensionality and rich details. This limits the designer's creativity and makes it difficult for products to compete in differentiated appearance. In addition, there are also some problems when dispensing glue on the surface of injection molded parts. At present, the glue needs to be pressurized each time it is dispensed, and the stability and uniformity of the pressurization are difficult to guarantee, resulting in differences in the amount of glue discharged during dispensing. This difference not only affects the uniformity of dispensing, but may also cause unevenness and bubbles on the product surface.

[0003] For example, the Chinese invention patent (application number: CN201510155213.6) discloses "a molding process, processing equipment and shell decoration of a shell decoration", and its specification discloses: in addition to the installation and protection functions, the shell of electronic products also has the functions of decoration, improving product quality, enriching appearance and experiencing touch reality. For example, mobile phones and digital products are particularly particular about the shape and decoration of the shell. At present, in the production and processing of electronic product shells, such as mobile phones and digital products, the curved structure shells are mostly injection molded. In view of the current existing situation that the glue needs to be pressurized every time the glue is dispensed, and the stability and uniformity of the pressurization are difficult to guarantee, resulting in differences in the amount of glue discharged during the dispensing.

[0004] Therefore, we make improvements to this and propose a double-layer texture processing device and method. Summary of the invention

[0029] 2. In order to solve the problem in the prior art that the surfaces of some injection molded parts that have been glued need to be flattened, the present application sets a glue dispensing mechanism.

The gear ring 203 is rotatably installed in the middle of the inner cavity of the tray 201. A fixing frame 204 is fixedly installed at the bottom of the inner cavity of the tray 201. A conduit 205 is rotatably installed in the middle of the fixing frame 204. A glue storage box 104 is fixedly installed on the top side of the support plate 101. The top of the glue storage box 104 is fixedly connected to both sides of the tray 201 through a hose 106 and communicated with both ends of the conduit 205.

[0048] A fixed plate 207 is fixedly installed in the middle of the conduit 205, and a storage groove 210 is symmetrically arranged on the surface of the fixed plate 207. A glue outlet pipe 211 is movably hinged at the outer end of the storage groove 210, and a round head 213 is fixedly installed at the bottom of the glue outlet pipe 211. The round head 213 is rotatably installed in the storage groove 210 and communicated with the inside of the conduit 205. A sealing plate 212 is installed in a circular array on the top of the glue outlet pipe 211. The sealing plate 212 is movably hinged to the top of the glue outlet pipe 211 through a torsion spring. A roller 208 is sleeved on the outer side of the fixed plate 207. A glue dispensing head 209 is slidably installed on the outer circumferential array of the roller 208. A top pipe 214 is fixedly connected to the bottom of the glue dispensing head 209, and the top pipe 214 is vertically located on the outer side of the sealing plate 212.

[0049] A gear 219 is fixedly installed at one end of the conduit 205, and teeth are provided at the bottom of the gear ring 203 and mesh with the gear 219. After the injection molded part is placed on the top of the base 301, the height of the tray 201 is controlled by the first motor 102, so that the glue dispensing head 209 at the bottom of the tray 201 is attached to the surface of the injection molded part.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0054] Example 1, please refer to Figure 1-Figure 7A double-layer texture processing device includes a box body 1, a support plate 101 is fixedly installed in the middle of the box body 1, a feeding mechanism 3 is provided on the top of the support plate 101, a dispensing mechanism 2 is provided just above the feeding mechanism 3, the dispensing mechanism 2 includes a tray 201, a first motor 102 is fixedly installed on the bottom side of the support plate 101, the tray 201 is threadedly connected to the output end of the first motor 102, a second electric cylinder 105 is provided at the bottom of the tray 201 to control the movement of the tray 201, and the inside of the tray 201 A second motor 202 is fixedly installed in the middle of the cavity, and a gear ring 203 is fixedly connected to the output end of the second motor 202. The gear ring 203 is rotatably installed in the middle of the inner cavity of the tray 201. A fixing frame 204 is fixedly installed at the bottom of the inner cavity of the tray 201. A conduit 205 is rotatably installed in the middle of the fixing frame 204. A glue storage box 104 is fixedly installed on the top side of the support plate 101. The top of the glue storage box 104 is fixedly connected to both sides of the tray 201 through a hose 106 and is connected to both ends of the conduit 205.

[0055] A fixed plate 207 is fixedly installed in the middle of the conduit 205, and a storage groove 210 is symmetrically arranged on the surface of the fixed plate 207. A glue outlet pipe 211 is movably hinged at the outer end of the storage groove 210, and a round head 213 is fixedly installed at the bottom of the glue outlet pipe 211. The round head 213 is rotatably installed in the storage groove 210 and communicated with the inside of the conduit 205. A sealing plate 212 is installed in a circular array on the top of the glue outlet pipe 211. The sealing plate 212 is movably hinged to the top of the glue outlet pipe 211 through a torsion spring. A roller 208 is sleeved on the outer side of the fixed plate 207. A glue dispensing head 209 is slidably installed on the outer circumferential array of the roller 208. A top pipe 214 is fixedly connected to the bottom of the glue dispensing head 209, and the top pipe 214 is vertically located on the outer side of the sealing plate 212.

[0056] A gear 219 is fixedly installed at one end of the conduit 205, and teeth are provided at the bottom of the gear ring 203 and mesh with the gear 219. Threaded rods 206 are provided at both ends of the conduit 205, and sleeves 215 are threadedly connected to the threaded rods 206. A sliding tube 216 is provided on the inner side of the sleeve 215. The sliding tube 216 is wrapped around the surface of the conduit 205, and the sleeve 215 is sleeved on the surface of the roller 208. The surface of the sliding tube 216 is provided with a circumferential array of clearance grooves 217. The clearance grooves 217 are located directly below the dispensing head 209. The dispensing head 209 is magnetically adsorbed and penetrates the inner wall of the roller 208. The sleeve 216 is provided with a plurality of sliding grooves 217. Four telescopic slots are provided at equal angles on the side wall of the sleeve 215. A limit rod 218 is fixedly installed inside the telescopic slot on the side wall of the sleeve 215. Both ends of the limit rod 218 are provided with a telescopic electromagnet 220. The electromagnet 220 extends outward and can be stuck in the inner wall of the fixing frame 204 and the tray 201. The threaded rods 206 at both ends of the conduit 205 are symmetrically arranged. When they rotate synchronously, the sleeves 215 at both ends move inward or outward synchronously. When the sleeve 215 moves inward, the dispensing head 209 is squeezed into the inside of the giving way slot 217. The sliding tube 216 makes the dispensing tube 211 tilt and fit inside the storage slot 210.

[0057] Before dispensing glue on the injection molded part, the engagement between the electromagnet 220 and the tray 201 can be used to drive the toothed ring 203 to drive the sleeve 215 to move, and then adjust the sleeve 215 to wrap the dispensing head 209, so as to control the amount of the dispensing head 209 extending, and then adjust the range and length of the dispensing of the dispensing head 209, so as to achieve dispensing of glue on different areas. After the dispensing is completed, the dispensing position needs to be flattened with glue. At this time, the toothed ring 203 can be used to control the sleeve 215 to completely wrap the dispensing head 209. At this time, the glue outlet pipe 211 will be automatically stored in the inside of the storage groove 210 under the squeezing of the give way groove 217, so as to facilitate the smooth surface of the sleeve 215 to be flattened on the surface of the injection molded part. After the sleeve 215 is pushed out from the surface of the dispensing head 209, the glue outlet pipe 211 will automatically stand up vertically from the inside of the storage groove 210 under the adsorption of the dispensing head 209 at its top, and align with the top pipe 214.

[0058] In order to solve the problem in the prior art that the surfaces of some injection molded parts that have been glued need to be flattened with glue, the present application sets up a glue dispensing mechanism 2. After the glue dispensing mechanism 2 completes the glue dispensing, the sleeve 215 is wrapped around the surface of the roller 208 through structural changes, and rotates synchronously with the gear ring 203, so that the tray 201 can flatten the glue on the surface of the injection molded part during the movement, thereby achieving the flattening of the glue on the surface of the injection molded part and making the glue dispensing more uniform after flattening.

[0059] Example 2, further optimizes the double-layer texture processing equipment provided in Example 1, specifically, as follows Figure 8 and Fig. 9 As shown, the feeding mechanism 3 includes a base 301, a floor groove 302 is opened in the middle of the base 301, a negative pressure chamber 303 is arranged at the bottom of the floor groove 302, a piston plate 304 is vertically slidably installed inside the negative pressure chamber 303, a lifting cylinder 305 is fixedly installed on the top of the piston plate 304, a piston head 306 is slidably installed inside the lifting cylinder 305, the piston head 306 is fixedly connected to the telescopic end of the first electric cylinder 103, four suction cups 307 are arranged in a circular array on the top of the lifting cylinder 305, a telescopic rod 308 is slidably installed inside the suction cup 307, a chuck 309 is fixedly connected to the outside of the telescopic rod 308, the middle part of the chuck 309 is located in the middle part of the suction cup 307 and a support spring 310 is sleeved, the support spring 310 supports the telescopic rod 308 outward, and the piston Four telescopic tubes 311 are provided in a circular array on the top of the plate 304. The top of the telescopic tube 311 is fixedly connected to the bottom of the suction cup 307. A connecting hole 312 is opened in the middle of the telescopic tube 311 and is connected to the negative pressure chamber 303. The lifting cylinder 305 is raised by the first electric cylinder 103, and then the injection molded part is placed on the top of the lifting cylinder 305. Then, the lifting cylinder 305 is controlled to descend again by the first electric cylinder 103. At this time, the telescopic rods 308 on the four sides of the lifting cylinder 305 will automatically move the four corners of the injection molded part to the middle under the action of negative pressure by the chuck 309, so as to automatically move the injection molded part to the center position of the processing. In the process of continuing to move downward, the suction cup 307 adsorbs the bottom of the injection molded part through the action of negative pressure, so as to fix the injection molded part.

[0060] By setting up the feeding mechanism 3, the first electric cylinder 103 is used to control the lifting cylinder 305 to be lifted and lowered. When the lifting cylinder 305 is lifted, the injection molded part can be placed on the top of the lifting cylinder 305. At this time, the first electric cylinder 103 controls the lifting cylinder 305 to descend, and negative pressure is generated inside the lifting cylinder 305, so that the clamp 309 automatically moves with the telescopic rod 308, thereby clamping and fixing the four corners of the injection molded part, and moving the injection molded part to the center of the lifting cylinder 305. At the same time, the injection molded part is adsorbed on the top of the suction cup 307 by the adsorption effect of the negative pressure, so as to realize automatic adjustment of the position of the injection molded part and adsorb and fix the injection molded part, thereby solving the problem of manual adjustment required to place the injection molded part in the center of the base in the prior art.

[0061] Embodiment 3, a method for double-layer texture processing, the method is as follows:

[0062] Step 1: Control the lifting cylinder 305 to rise by the first electric cylinder 103, and place the injection molded part on the top of the lifting cylinder 305;

[0063] Step 2: The piston head 306 is controlled to descend by the first electric cylinder 103 and the piston plate 304 is caused to descend. At this time, the piston head 306 sucks the interior of the lifting cylinder 305 into a vacuum, and the telescopic rod 308 automatically moves the clamp 309 inward under the action of the negative pressure, thereby limiting the four corners of the injection molded part;

[0064] Step 3: When the lifting cylinder 305 descends, negative pressure is generated inside the telescopic tube 311, and the injection molded part is adsorbed on the top of the suction cup 307 to fix the injection molded part;

[0065] Step 4: The first motor 102 is used to control the dispensing mechanism 2 to descend to a specified height. First, the limit rod 218 is inserted into the inner wall of the fixing frame 204 and the tray 201. At this time, the second motor 202 is used to control the gear ring 203 to rotate, so that the gear ring 203 drives the gear 219 to rotate, thereby rotating the guide tube 205, and then moving the sleeve 215 inward, thereby adjusting the extension amount of the dispensing head 209 to achieve control of the dispensing length;

[0066] Step 5: After the adjustment of the extension amount of the dispensing head 209 is completed, the electromagnet 220 is retracted and disengaged from the inside of the tray 201 and the fixing frame 204. At this time, the second motor 202 drives the gear ring 203 to pull the gear 219 to rotate, so that the roller 208 rotates synchronously, and the second electric cylinder 105 controls the movement of the tray 201, so that the dispensing head 209 can apply glue to the surface of the injection molded part when it contacts the injection molded part;

[0067] Step 6. After the glue dispensing is completed, the glue needs to be flattened. The electromagnet 220 is inserted into the side wall of the tray 201 again. At this time, the second motor 202 controls the gear ring 203 to drive the sleeve 215 to completely wrap the surface of the roller 208, and then the sleeve 215 is driven by the second electric cylinder 105 to flatten the glue on the surface of the injection molded part.

[0068] The use process of the double-layer texture processing device and method provided by the present invention is as follows:

[0069] The lifting cylinder 305 is raised by the first electric cylinder 103, and then the injection molded part is placed on the top of the lifting cylinder 305. Then, the lifting cylinder 305 is lowered by the first electric cylinder 103 again. At this time, the telescopic rods 308 on the four sides of the lifting cylinder 305 will automatically move the four corners of the injection molded part to the middle under the action of negative pressure, thereby automatically moving the injection molded part to the center position of the processing. In the process of continuing to move downward, the suction cup 307 adsorbs the bottom of the injection molded part under the action of negative pressure, thereby fixing the injection molded part.

[0070] The height of the tray 201 is controlled by the first motor 102, so that the glue dispensing head 209 at the bottom of the tray 201 is attached to the surface of the injection molded part. At this time, the second motor 202 drives the gear ring 203 to pull the guide tube 205 to rotate, so that the guide tube 205 and the glue dispensing head 209 rotate synchronously, and in the process of rotation, the glue dispensing head 209 and the surface of the injection molded part are squeezed, so that the glue dispensing head 209 moves inward, and the top tube 214 is connected with the glue outlet tube 211, so that the glue dispensing head 209 adheres the glue to the surface of the injection molded part;

[0071] Before dispensing glue on the injection molded part, the engagement between the electromagnet 220 and the tray 201 can be used to drive the toothed ring 203 to drive the sleeve 215 to move, and then adjust the sleeve 215 to wrap the dispensing head 209, so as to control the amount of the dispensing head 209 extending, and then adjust the range and length of the dispensing of the dispensing head 209, so as to achieve dispensing of glue on different areas. After the dispensing is completed, the dispensing position needs to be flattened with glue. At this time, the toothed ring 203 can be used to control the sleeve 215 to completely wrap the dispensing head 209. At this time, the glue outlet pipe 211 will be automatically stored in the inside of the storage groove 210 under the squeezing of the give way groove 217, so as to facilitate the smooth surface of the sleeve 215 to be flattened on the surface of the injection molded part. After the sleeve 215 is pushed out from the surface of the dispensing head 209, the glue outlet pipe 211 will automatically stand up vertically from the inside of the storage groove 210 under the adsorption of the dispensing head 209 at its top, and align with the top pipe 214.
