Description

Technical Field

[0001] The present invention belongs to the technical field of mobile phone cover processing, and relates to an automatic processing device and processing method for mobile phone covers. Background Art

[0002] The cover plate of a mobile phone is the outer screen of the mobile phone, or the protective glass of the mobile phone shell. The mobile phone cover plate not only serves as a decoration for the mobile phone, but also can play a role in protecting the mobile phone, such as anti-falling, anti-scratching, waterproofing and shockproofing.

[0003] In the processing of existing mobile phone cover plates, there are multiple processes such as cutting and grinding. Each process needs to be transferred multiple times during processing to be completed. As a result, during the process of process transfer, there are scratches on the cover plate, and repositioning and clamping are required during each process of processing, increasing the difficulty of positioning and clamping. When processing in the next process, due to the inability to achieve clamping and positioning during the processing of the cover plate, the defective rate of the cover plate and the loss of cover plate materials increase. In addition, when grinding the surface of the cover plate, intelligent and precise arc surface grinding of the cover plate surface cannot be performed, resulting in too deep or too shallow grinding depth, affecting the quality of cover plate processing, and at the same time, automatic and intelligent processing of the cover plate surface cannot be achieved.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figures 1-10 As shown in the figure, an automatic processing device for a mobile phone cover plate includes a processing bottom plate 1, a cutting limit seat 2, a splitting mechanism 3 and a grinding and processing mechanism 4. A cutting limit seat 2 is provided on the processing bottom plate 1, and a splitting mechanism 3 and a grinding and processing mechanism 4 are provided on the cutting limit seat 2.

[0045] The processing bottom plate 1 is provided with a groove 11, and a number of cutting limit seats 2 are arranged in an array in the groove 11. A support baffle is fixed on the processing bottom plate 1, and a first transmission lead screw 12 connected to the first power motor 14 and a second transmission lead screw 13 connected to the second power motor 15 are provided between the support baffles.

[0046] The cutting limit seat 2 includes an adsorption fixing plate 21, an end support block 22, a symmetric rotating cam 23 and an adsorption mechanism 27. The adsorption fixing plate 21 is provided with a first conduction groove 211 and a second conduction groove that are perpendicular to each other. An installation groove is opened at the bottom of the adsorption fixing plate 21 located at the center of the cutting limit seat 2, and the installation groove is communicated with the first conduction groove 211 and the second conduction groove. A transmission motor 25 is fixed in the installation groove. The transmission shaft 24 is connected to the adsorption fixing plate 21 through a bearing. One end of the transmission shaft 24 is fixedly connected to the transmission motor 25, and the other end is fixed with a symmetric rotating cam 23. An adsorption mechanism 27 is provided on the symmetric rotating cam 23. Tooth teeth 26 that cooperate with a synchronous transmission rack 29 penetrating the first conduction groove 211 are distributed on the circumferential side of the transmission shaft 24 near one end of the symmetric rotating cam 23. Both ends of the symmetric rotating cam 23 are respectively hinged to a feed connecting rod 28 penetrating the second conduction groove, and the feed connecting rod 28 is hinged to the end support block 22. A knife cutting groove is provided on the end support block 22, and the knife cutting groove prevents the knife from colliding with the end support block 22 when cutting the cover plate and damaging the blade.

[0047] The bottom of the adsorption mechanism 27 is in sliding fit with the upper end surface of the symmetric rotating cam 23. The adsorption mechanism 27 is connected to the adsorption fixing plate 21 through a connecting plate to limit the rotation of the adsorption mechanism 27 along with the symmetric rotating cam 23, so that the adsorption mechanism 27 does not rotate synchronously with the symmetric rotating cam 23. When the drive motor 25 works, it drives the transmission shaft 24 to rotate. The teeth 26 on the circumferential side of the transmission shaft 24 are engaged with the synchronous transmission rack 29 to synchronously drive the transmission shafts 24 on other cutting and limiting seats 2 to rotate. After the transmission shaft 24 rotates, it drives the symmetric rotating cam 23 to rotate, and then drives the end support block 22 to move closer to or away from the adsorption mechanism 27 through the feed connecting rod 28, realizing the equidistant adjustment of the end support blocks 22 on both sides of the adsorption fixing plate 21 and the adsorption fixing plate 21.

[0048] The adsorption mechanism 27 includes an adsorption disc 271, a buffer spring 273, an adsorption support column 274 and an adsorption plug 275. The adsorption disc 271 is arranged on the symmetric rotating cam 23 through a telescopic plate 272. An extension retaining ring is arranged at the lower end of the adsorption disc 271. Both the extension retaining ring and the adsorption disc 271 are made of rubber material. An adsorption plug 275 is fixed on the adsorption support column 274. The adsorption plug 275 is hemispherical. The outer diameter of the adsorption disc 271 is larger than that of the extension retaining ring. One end of the buffer spring 272 is connected to the adsorption support column 274, and the other end is connected to the bottom of the adsorption disc 271. When the cover plate to be processed is placed on the cutting and limiting seat 2, by pressing the cover plate downward, the adsorption mechanism 27 moves downward, and the buffer spring 273 is compressed until the adsorption plug 275 penetrates through the extension retaining ring. Under the restoring force of the buffer spring 273, the extension retaining ring on the adsorption disc 271 is pushed to be in close contact with the adsorption plug 275, and then a sealed space is formed among the cover plate, the adsorption disc 271, the extension retaining ring and the adsorption disc 271, which can tightly adsorb the cover plate, realize the effective fixation of the position of the cover plate, and does not damage the cover plate.

[0049] The dividing mechanism 3 includes a dividing support plate 31, a first transmission connecting plate 32, a longitudinal dividing assembly and a dividing cutting piece. The dividing support plate 31 is fixedly connected to the first transmission connecting plate 32 through an electric telescopic rod. The first transmission connecting plate 32 is provided with a first limiting hole and a first threaded hole matched with the first transmission lead screw 12. A first limiting bearing 322 is arranged in the first limiting hole. The inner ring of the first limiting bearing 322 is matched with the second transmission lead screw 13 through a threaded guide tube 321. When the first power motor 14 drives the first transmission lead screw 12 and the second power motor 15 drives the second transmission lead screw 13 to rotate, the first transmission connecting plate 32 moves along the axial direction of the first transmission lead screw 12 under the limiting action of the threaded guide tube 321 and the first limiting bearing 322.

[0050] A number of split cutting pieces are equally spaced on the split support plate 31. The split cutting pieces include a pressing and limiting block 35, a positive and negative lead screw 37, a cutting tool 38, and a split clamping plate 39. A sliding groove 312 is formed on the split cutting piece. A pressing and limiting block 35 is slidably disposed in the sliding groove 312. The pressing and limiting block 35 is connected to the inner wall of the split cutting piece through a telescopic spring 36. The positive and negative lead screw 37 penetrates the split cutting piece, and both ends of the positive and negative lead screw 37 are in threaded cooperation with the split clamping plate 39 respectively. A groove matching the cutting tool 38 is formed on the inner side of the split clamping plate 39. Both sides of the cutting tool 38 are pressed and limited by the pressing and limiting block 35, and both ends of the cutting tool 38 are clamped and fixed by the split clamping plate 39 to limit the cutting tool 38 from moving along the cutting direction. Through the pressing and limiting block 35, the positive and negative lead screw 37, and the split clamping plate 39, the cutting tool 38 can be effectively positioned and restricted, which is convenient for the disassembly and replacement of the cutting tool 38.

[0051] A guiding groove 311 is formed on the split support plate 31. The longitudinal splitting assembly includes a third transmission lead screw 33 disposed in the guiding groove 311, a splitting motor 34 connected to the third transmission lead screw 33, a guiding splitting plate 301, a splitting moving frame 302, and a limiting pressing plate 304. A guiding splitting limiting groove is formed on the guiding splitting plate 301. A number of clamping holes 3012 are arrayed in the guiding splitting limiting groove. The splitting moving frame 302 is slidably matched with the guiding splitting plate 301. A longitudinal cutting tool 307 is fixed at the lower end of the splitting moving frame 302. The splitting moving frame 302 is fixedly connected to a moving push plate 303 slidably matched with the guiding splitting limiting groove. A clearance groove 3011 is formed in the moving push plate 303. Two symmetrical limiting pressing plates 304 are slidably disposed in the clearance groove 3011. A return spring 306 is disposed between the two limiting pressing plates 304. A clamping block 305 matching the clamping hole 3012 on the guiding splitting plate 301 is disposed at the end of the limiting pressing plate 304. When the symmetrical rotating cam 23 rotates, the relative position of the end support block 22 is adjusted through the feed connecting rod 28. When the distance between the end support block 22 and the adsorption fixing plate 21 is fixed, manually press the limiting pressing plate 304 and adjust the relative position of the splitting moving frame 302 on the guiding splitting plate 301. When moving to directly above the end support block 22, release the limiting pressing plate 304. Under the action of the return spring 306, the clamping block 305 at the end of the limiting pressing plate 304 is matched with the clamping hole 3012 on the guiding splitting plate 301 to realize the position limitation of the splitting moving frame 302, meeting the matching between the end support block 22 and the position of the longitudinal splitting assembly.

[0052] The grinding mechanism 4 includes a grinding support plate 41, a second transmission connecting plate 42 and several groups of surface grinding components. The grinding support plate 41 is fixedly connected to the second transmission connecting plate 42 through an electric telescopic rod. The second transmission connecting plate 42 is provided with a second limit hole and a second threaded hole that cooperates with the second transmission lead screw 13. A second limit bearing 422 is arranged in the second limit hole. The inner ring of the second limit bearing 422 is matched with the first transmission lead screw 12 through a threaded guide cylinder 421. When the first power motor 14 drives the first transmission lead screw 12 and the second power motor 15 drives the second transmission lead screw 13 to rotate, the second transmission connecting plate 42 moves along the axial direction of the second transmission lead screw 13 under the limiting action of the threaded guide cylinder 421 and the second limit bearing 422.

[0053] Several groups of surface grinding components are arranged on the grinding support plate 41. The surface grinding components include a central grinding plate 43 and a side grinding unit 44. The central grinding plate 43 is connected to the side grinding unit 44 through a hinge shaft. The side grinding unit 44 located at the end of the grinding support plate 41 is connected to the first telescopic rod 45. Two adjacent side grinding units 44 are fixedly connected to the second telescopic rod 46 through a grinding connecting rod 47. When the first telescopic rod 45 and the second telescopic rod 46 are adjusted, the relative inclination angle of the side grinding unit 44 can be adjusted to meet different radian angles of the cover plate surface.

[0054] A grinding cavity 441 is formed in the side grinding unit 44. A first pulley 443, a transmission belt 444 and several second pulleys 445 are arranged in the grinding cavity 441. The first pulley 443 is connected to a grinding motor through a grinding connecting shaft 442. One end of the second pulley 445 is connected to a grinding transmission cylinder 446, and the other end is connected to the grinding support plate 41 through a rotating shaft, so that the second pulley 445 can rotate around the axis of the rotating shaft. The transmission belt 444 cooperates with the first pulley 443 and several second pulleys 445 respectively. When the grinding motor works, it drives the first pulley 443 to rotate, and drives the transmission belt 444 through the first pulley 443 to synchronously drive several second pulleys 445 to rotate synchronously. Furthermore, several grinding transmission cylinders 446 connected through the transmission belt 444 work synchronously to grind the surface and side of the cover plate synchronously. The surface inclination angle of the cover plate after grinding can be adjusted by adjusting the inclination angle of the side grinding unit 44.

[0055] The grinding drive cylinder 446 includes a grinding drive frame 4461. At the lower end of the grinding drive frame 4461, there are grinding drive teeth 4462. Inside the grinding drive frame 4461, it is connected to a grinding sliding plate 4467 through a grinding limit spring 4463. The grinding sliding plate 4467 is connected to a grinding disc 4465 through a grinding drive shaft 4464. Around the grinding drive shaft 4464, there are limit drive teeth 4466 that mesh with the grinding drive teeth 4462. When the grinding disc 4465 contacts the surface of the cover plate to be ground, as the electric telescopic rod extends, the contact pressure between the grinding disc 4465 and the cover plate surface increases, and the grinding disc 4465 moves towards the direction close to the second pulley 445 until the limit drive teeth 4466 mesh with the grinding drive teeth 4462, driving the grinding disc 4465 to rotate, and then enabling the grinding disc 4465 to grind the surface of the cover plate. As the electric telescopic rod extends further, the limit drive teeth 4466 disengage from the grinding drive teeth 4462, and the grinding disc 4465 stops grinding the surface of the cover plate continuously.

[0056] An automated processing method for a mobile phone cover plate includes the following steps:

[0057] Step 1: Place the cover plate to be processed on the cutting limit seat 2, and manually press the cover plate downward so that the adsorption mechanism 27 adsorbs the cover plate.

[0058] Step 2: Start the drive motor 25 and adjust the distance between the adsorption fixing plate 21 and the end support block 22.

[0059] Step 3: Start the first power motor 14 and the second power motor 15, drive the dividing support plate 31 and the grinding support plate 41 to move along the axis direction of the first transmission lead screw 12, and achieve the processing of cutting first and then grinding.

[0060] Step 4: Manually press the limit pressing plate 304, adjust the position of the dividing moving frame 302 relative to the guiding dividing plate 301. When adjusted to an appropriate position, release the limit pressing plate 304 to lock and fix the position of the dividing moving frame 302.

[0061] Step 5: According to the inclination angle of the surface of the cover plate to be ground, adjust the first telescopic rod 45 and the second telescopic rod 46 to meet the grinding inclination angle of the side grinding unit 44.

[0062] Step 6: Start the grinding motor, drive the grinding connecting shaft 442 to rotate through the grinding motor, and drive the grinding drive cylinder 446 to grind the surface of the cover plate through the transmission belt 444.
