Description

Technical Field

[0001] This utility model relates to the field of mobile phone back panel processing technology, specifically a deburring processing device for mobile phone back panels. Background Technology

[0002] Depending on the specific requirements, mobile phone back panels are made of plastic, metal, or other lightweight, high-strength materials. Current mobile phone back panel injection molds contain multiple cavities and cores. After production, the surface of the mobile phone back panel will have sprue marks, which need to be cut off with a cutting tool. After that, there will be some burrs at the cut, which need to be deburred.

[0003] According to a deburring device for mobile phone casings disclosed in patent publication number CN217394557U, the device includes a base with a groove on its top surface. A support platform is vertically connected to the bottom surface of the inner wall of the groove. A sliding plate is longitudinally slidably connected to one side edge of the top surface of the base. A first telescopic motor is fixedly connected to the top surface of the sliding plate. The output of the first telescopic motor is driven by a first guide rod. A rotary motor is fixedly connected to the end of the first guide rod. A mounting bracket is fixedly connected to the bottom surface of the rotary motor. A rotating shaft is driven by the output end of the rotary motor. The rotating shaft passes through the top surface of the mounting bracket and extends to the bottom of the mounting bracket. The rotating shaft is rotatably connected to the top surface of the mounting bracket. A cutting disc is sleeved on the outer edge of the rotating shaft. A stop block is attached to the top surface of the cutting disc. The stop block is fixedly sleeved on the outer edge of the rotating shaft. Sandpaper is attached to the bottom surface of the cutting disc.

[0004] While the aforementioned technical solution creates a negative pressure zone between the phone case mounted on the top surface of the support platform and the top surface of the support platform by connecting multiple air holes through the support platform and creating cavities communicating with the air holes, and by connecting an air pump and air pipe to the bottom surface of the support platform to draw air downwards, thus stabilizing the sprue on the phone during cutting, the simple negative pressure fixation, while keeping the phone back panel stationary in a static state, becomes extremely unstable during cutting with a cutting blade and sanding with sandpaper. This unstable state easily leads to displacement, making effective deburring impossible and affecting the processing effect. Therefore, we provide a deburring processing device for phone back panels to solve this problem. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 A deburring processing device for mobile phone back panel includes a substrate 1. The upper end of the substrate 1 is connected to a carrier plate 3 via a support column 2. An electrostatic adsorption film 8 is adhered to the upper end of the carrier plate 3. The electrostatic adsorption film 8 adsorbs the mobile phone back panel and effectively protects its lower surface from wear during the deburring process.

[0027] The upper end of the carrier plate 3 is provided with a central hole 6, and through holes 7 are provided at equal intervals on both sides of the upper end of the carrier plate 3. The upper end of the substrate 1 is equipped with a fixing mechanism 4. The fixing mechanism 4 includes an adsorption component 41 installed on the upper end of the substrate 1. The adsorption component 41 includes a servo motor 411 installed on the upper end of the substrate 1. The output end of the servo motor 411 is connected to a double-threaded screw 417. A first fixing plate 412 is screwed to the upper outer side of the double-threaded screw 417. The upper end of the first fixing plate 412 is connected to a vacuum suction cup 414 through a connecting post 413. A first positioning block 415 is symmetrically connected to the outer side of the first fixing plate 412. A positioning post 416 is symmetrically installed on the upper end of the substrate 1 and movably sleeved therewith. A first gear 418 is installed in the middle of the outer side of the double-threaded screw 417.

[0028] The servo motor 411 is turned on by an external control switch. The output end of the servo motor 411 drives the positive and negative double threaded rod 417 to rotate. The first fixing plate 412 on the outside of the positive and negative double threaded rod 417 then moves upward. The first positioning blocks 415 on both sides of the first fixing plate 412 move upward at the outer limit of the positioning post 416. Thus, the first fixing plate 412 drives the connecting post 413 and the vacuum suction cup 414 at its upper end to move upward and adhere to the lower end of the mobile phone back panel placed on the upper end of the carrier plate 3 for fixation. This facilitates stable deburring operation.

[0029] The upper end of the adsorption component 41 corresponds to the position of the central hole 6. A clamping component 42 is movably connected to the outer side of the adsorption component 41. Two sets of T-slots 9 are provided on the upper end of the substrate 1. The clamping component 42 includes a T-shaped rod 427 that slides with the T-slot 9. A support plate 422 is connected to the upper end of each of the two T-shaped rods 427. A toothed plate 421 that meshes with the first gear 418 is connected to the outer side of each support plate 422. A vertical plate 423 is connected to the upper end of each support plate 422. A clamping block 424 is connected to the upper end of each vertical plate 423. A silicone pad 425 is adhered to one side of the clamping block 424. Limiting holes 426 are provided on the outer side of each vertical plate 423. Limiting posts 10 that are inserted into the limiting holes 426 are respectively installed on both sides of the carrier plate 3.

[0030] When the output of the servo motor 411 drives the double-threaded rod 417 to rotate, the double-threaded rod 417 synchronously drives the first gear 418 to rotate. The first gear 418 then drives the two meshing toothed plates 421 on its outer sides to move in the same direction. The two toothed plates 421 synchronously drive the support plate 422 and the vertical plates 423 and T-shaped rods 427 at both ends to move. The T-shaped rods 427 move within the inner cavity of the T-slot 9, effectively improving the stability of the support plate 422 driving the vertical plates 423 and the clamping block 424 at its upper end to move. The support plate 422 moves further to the outside of the limiting post 10 through the limiting hole 426, which further improves the stability of the movement of the support plate 422. The support plate 422 drives the clamping block 424 and its outer silicone pad 425 to move towards the two sides of the mobile phone back panel placed on the upper end of the carrier plate 3 and effectively clamps it, which further improves the stability of the deburring operation of the mobile phone back panel. The silicone pad 425 is in close contact with the two sides of the mobile phone back panel, which effectively improves the anti-damage protection effect of clamping it.

[0031] An elevating assembly 43 is screwed to the outside of the adsorption assembly 41. The upper end of the elevating assembly 43 corresponds to the position of the through hole 7. The elevating assembly 43 includes a second fixing plate 431 screwed to the lower part of the outer side of the double-threaded rod 417. A second positioning block 432 that is movably sleeved with the positioning post 416 is symmetrically connected to the outer side of the second fixing plate 431. A fixing plate 433 is connected to one side of each of the second positioning blocks 432. A connecting rod 436 is connected between the fixing plate 433 and the second positioning block 432. The upper end of the fixing plate 433 is equidistantly connected to the top post 434 corresponding to the position of the through hole 7. A rubber block 435 is glued to the upper end of each top post 434.

[0032] When the output of the servo motor 411 drives the double-threaded rod 417 to rotate, the second fixed plate 431 on the outer side of the double-threaded rod 417 moves downward. The second positioning blocks 432 on both sides of the second fixed plate 431 move downward at the outer side of the positioning post 416, thereby driving the fixed plate 433 and its upper top post 434 to move downward. After the deburring operation of the mobile phone back panel is completed, the external vacuum pumping device of the vacuum suction cup 414 performs a pressure relief operation, and the vacuum suction cup 414 releases its suction from the mobile phone back panel. At the same time, the reverse switch of the servo motor 411 is turned on. As a result, the vacuum suction cup 414 of the adsorption component 41 moves downward away from the back panel of the mobile phone, and at the same time, the clamping block 424 of the clamping component 42 also moves away from the vacuum suction cup 414. Meanwhile, the second fixing plate 431 of the top material component 43 moves upward, thereby driving the second positioning block 432 to move upward. The second positioning block 432 drives multiple top posts 434 to move upward through the fixing plate 433. The top posts 434 pass through the through hole 7 and push the back panel of the mobile phone upward, making it convenient for the operator to pick up. Furthermore, the rubber block 435 at the upper end of the top post 434 fits against the back panel of the mobile phone, effectively improving the anti-damage effect of the top material.

[0033] A deburring mechanism 5 is installed on the upper end of the substrate 1. The deburring mechanism 5 includes a side plate 51 installed on the upper end of the substrate 1. A mounting plate 52 is installed on the outer side of the side plate 51. A translation cylinder 53 is installed on the upper end of the mounting plate 52. A connecting plate 54 is connected to the output end of the translation cylinder 53. A lifting cylinder 55 is installed on the upper end of the connecting plate 54. A top plate 56 is connected to the output of the lifting cylinder 55. A deburring assembly is installed on the lower end of the top plate 56. The deburring assembly includes a cutting motor 57 installed on the lower end of the top plate 56. A drive shaft 510 is connected to the output end of the cutting motor 57. A cutting blade 511 is installed on the lower end of the drive shaft 510. A support shaft 58 is rotatably connected to the lower end of the top plate 56. A grinding wheel 512 is installed on the lower end of the support shaft 58. A meshing second gear 59 is installed on the outer side of both the support shaft 58 and the drive shaft 510.

[0034] After the phone back panel is fixed by the fixing mechanism 4, the lifting cylinder 55 is turned on by the external control switch. The output end of the lifting cylinder 55 drives the top plate 56 and the deburring assembly to move down until the deburring assembly contacts the upper end of the phone back panel. Then, the cutting motor 57 and the translation cylinder 53 are turned on. The output end of the cutting motor 57 drives the drive shaft 510 and the cutting blade 511 at its lower end to rotate, which facilitates the removal of the sprue at the upper end of the phone back panel. The second gear 59 on the outside of the drive shaft 510 drives another second gear 59 and the support shaft 58 in its inner cavity to rotate. The support shaft 58 drives the grinding wheel 512 to rotate. At the same time, the output end of the translation cylinder 53 drives the connecting plate 54, the lifting cylinder 55, the top plate 56 and the entire deburring assembly to move horizontally from front to back, which facilitates the cutting blade 511 to effectively and completely remove the sprue at the upper end of the phone back panel. After the sprue is removed, the grinding wheel 512 rotates and grinds, which facilitates the quick grinding and deburring operation and effectively improves work efficiency.

[0035] Working principle: The system is controlled by an external control switch connected to the servo motor 411, translation cylinder 53, lifting cylinder 55, and cutting motor 57. During operation, the operator places the phone backplate on the carrier plate 3. Turning on the servo motor 411 causes its output to rotate the double-threaded screw 417. This causes the first fixing plate 412 on the outer side of the screw 417 to move upwards. Simultaneously, the first positioning blocks 415 on both sides of the first fixing plate 412 move upwards, limiting their movement to the outer side of the positioning post 416. This causes the first fixing plate 412 to move the connecting post 413 and its upper vacuum suction cup 414 upwards, contacting the lower end of the phone backplate placed on the carrier plate 3. At the same time, the double-threaded screw 417 synchronously drives the first gear 418 to rotate. The first gear 418 drives the two meshing toothed plates 421 on its outer side to move in the same direction. The two toothed plates 421 synchronously drive the support plate 422 and the vertical plates 423 and T-shaped rods 427 at both ends to move. The support plate 422 drives the clamping block 424 and the silicone pad 425 on its outer side to move towards the sides of the mobile phone back panel placed on the upper end of the carrier plate 3, and effectively clamps it, further improving the stability of the deburring operation of the mobile phone back panel. The silicone pad 425 is in close contact with the sides of the mobile phone back panel, effectively improving the anti-damage protection effect of clamping it. Then, the vacuum suction cup 414 is used for vacuuming operation through the external vacuum suction device, which facilitates the vacuum suction cup 414 to adsorb and fix the mobile phone back panel, effectively adsorbing and clamping the hand. After the back panel is stabilized, the lifting cylinder 55 is activated via an external control switch. The output of the lifting cylinder 55 moves the top plate 56 and the deburring assembly downwards until the deburring assembly contacts the upper part of the phone back panel. Then, the cutting motor 57 and the translation cylinder 53 are activated. The output of the cutting motor 57 drives the drive shaft 510 and its lower cutting blade 511 to rotate, facilitating the removal of the sprue at the upper part of the back panel. The second gear 59 on the outer side of the drive shaft 510 drives another second gear 59 and its inner support shaft 58 to rotate. The support shaft 58 then drives the grinding wheel 512 to rotate. Simultaneously, the output of the translation cylinder 53 drives the connecting plate 54, the lifting cylinder 55, the top plate 56, and the entire deburring assembly from front to back. The horizontal movement of the cutting blade 511 facilitates the effective and complete removal of the sprue at the upper end of the phone back panel. Simultaneously, after the sprue is removed, the grinding wheel 512 rotates and grinds, enabling rapid deburring and significantly improving work efficiency. After deburring the phone back panel, the external vacuum device of the vacuum suction cup 414 releases pressure, causing the vacuum suction cup 414 to release its grip on the phone back panel. Simultaneously, the reverse switch of the servo motor 411 is activated, causing the vacuum suction cup 414 of the adsorption component 41 to move downwards away from the phone back panel. At the same time, the clamping block 424 of the clamping component 42 also moves away from the vacuum suction cup 414. Meanwhile, the second fixing plate 431 of the ejector component 43 moves upwards, thereby causing the second positioning block 432 to move upwards.The second positioning block 432 moves multiple top posts 434 upwards via the fixing plate 433. The top posts 434 pass through the through holes 7 and push the phone back panel upwards, making it easy for operators to pick up. Furthermore, the rubber block 435 at the upper end of the top post 434 fits against the phone back panel, effectively improving the anti-damage effect of the ejector.
