Description

Technical Field

[0002] As an important part of a mobile phone, the housing of an electronic device, such as the back cover of a mobile phone, directly affects the appearance performance of the mobile phone in terms of its processing quality. When drilling holes in the frame of a mobile phone housing using traditional methods, the mobile phone housing is usually fixed before drilling. Currently, the mobile phone back cover is usually fixed by clamping. If the clamping is too tight, the mobile phone back cover will be deformed during clamping. If the clamping is loose, the hole positions of the processed mobile phone back cover will deviate, affecting the subsequent work. This drilling method not only has low efficiency but also is prone to clamping deviation, and the frame of the mobile phone housing is prone to deformation during the processing, resulting in a low yield rate.

[0003] In addition, currently, the axes of the holes formed in the frame of the mobile phone housing are usually perpendicular to the frame where they are located. When there are special requirements, such as drilling holes with axes forming an acute angle with the frame on the frame, it is difficult to achieve due to the limitations of fixture fixation and the influence of the strength of the mobile phone housing frame.

Detailed implementation manner

[0023] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0024] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Please refer to Figures 1 to 2 , the present invention provides a drilling device 100 for the frame of an electronic device housing, including a substrate 10, a driving mechanism 20 and a drilling mechanism 30 respectively fixed on the substrate 10, and a fixing mechanism 40 fixed on the driving mechanism 20.

[0027] Among them, the driving mechanism 20 includes at least one slide rail 21 fixed to the substrate 10, a slide plate 22 slidably connected to the slide rail 21, and a cylinder 23 fixedly connected to the slide plate 22. The fixing mechanism 40 includes a fixing plate 41 fixed to the slide plate 22 and a first clamp 42 fixed to the surface of the fixing plate 41 facing away from the slide plate 22. The electronic device housing 200 is clamped on the first clamp 42, and the cylinder 23 drives the slide plate 22 to reciprocate along the slide rail 21, so as to drive the electronic device housing 200 to approach or move away from the drilling mechanism 30, thereby realizing drilling of the electronic device housing 200.

[0028] Please refer to Figure 5 further, the electronic device housing 200 includes a frame 201, and the surface shape of the first clamp 42 facing away from the fixing plate 41 corresponds to the shape of the frame 201. The frame 201 is sleeved on the first clamp 42 to realize clamping and fixing of the frame and the first clamp 42. The first clamp 42 is an acrylic profiling clamp. The frame 201 sleeved on the first clamp 42 can not only support the frame 201, but also prevent the frame 201 from laterally shifting during the drilling process.

[0029] The fixing mechanism 40 further includes a second clamp 43. The second clamp 43 includes a support seat 431, a connecting arm 432 and a handle 433 that are rotatably connected to each other and respectively rotatably connected to the support seat 431, and a pressing plate 434 fixed to the end of the connecting arm 432 away from the support seat 431. Pressing the handle 433 makes the connecting arm 432 approach or move away from the first clamp 42, so as to drive the pressing plate 434 to abut against or move away from the first clamp 42 and the electronic device housing 200 fixed on the first clamp 42. The pressing plate 434 simultaneously presses the first clamp 42 and the electronic device housing 200 sleeved on the first clamp 42, preventing the frame 201 from longitudinally shifting during the drilling process, thereby ensuring the stability of the fixation of the frame 201.

[0030] In this embodiment, the fixing mechanism 40 further includes a plurality of positioning blocks 44 fixed to the fixing plate 41. The plurality of positioning blocks 44 are arranged around the edge of the first clamp 42. A buffer surface 441 is provided on the surface of each positioning block 42 away from the fixing plate 41 and facing the first clamp 42. The buffer surface 441 forms an obtuse angle with the fixing plate 41. The setting of the buffer surface 441 facilitates the electronic device housing 100 to quickly fall into the buffer space surrounded by the positioning plate 41, and then quickly sleeved on the first clamp 42, improving the accuracy and efficiency of the clamping of the electronic device housing 200 on the first clamp 42.

[0031] Please refer to Figure 3 and Figure 4 , the driving mechanism 20 also includes a mounting plate 24, and at least one first buffer assembly 25 and at least one second buffer assembly 26 respectively fixed to the two ends of the mounting plate 24. The slide rail 21 is fixed on the mounting plate 24 and fixedly connected to the base plate 10 through the mounting plate 24. The first buffer assembly 25 and the second buffer assembly 26 are respectively located at the two ends of the slide rail 21. The setting of the first buffer assembly 25 is used to ensure the stability of the drilling of the drilling mechanism 30 and to limit the depth of the drilling of the drilling mechanism 30. Specifically, when the frame 201 approaches the drilling mechanism 30 under the drive of the slide plate 22, the drilling is completed when the fixed plate 41 abuts against the first buffer assembly 25. The setting of the second buffer assembly 26 is used, on the one hand, to reduce the high speed of the fixed plate 41 driven by the cylinder 23, and on the other hand, to prevent the slide plate 22 from separating from the slide rail 21.

[0032] In this embodiment, there are two slide rails 21, and the slide plate 22 is sandwiched between the two slide rails 21 and slides along the slide rails 21 on the mounting plate 24 under the buffering of the two slide rails 21. Furthermore, each slide rail 21 is provided with a slot 211 on the surface facing the other slide rail 21, and the slide plate 22 extends toward both ends of the two slide rails 21 to form two card plates 221, and the two card plates 221 are accommodated in the corresponding two slots 211 and slide in the slots 211. The provision of the slots 211 and the card plates 221 is used to constrain the slide plate 22, prevent the slide plate 22 from being longitudinally shifted, ensure the positioning accuracy of the fixing mechanism 40, and further ensure the drilling accuracy of the electronic device housing frame drilling device 100.

[0033] In this embodiment, the first buffer assembly 25 includes a first baffle 251 fixedly connected to the mounting plate 24 and a first buffer structure 252 fixed to the first baffle 251. The second buffer assembly 26 includes a second baffle 261 fixedly connected to the mounting plate 24 and a second buffer structure 262 fixed to the second baffle 261. The cylinder 23 is fixed to the second baffle 261.

[0034] Furthermore, there are two first buffer assemblies 25 and two second buffer mechanisms 26 to ensure the stability of the fixed plate 41 during deceleration. When the first buffer mechanism 252 abuts against the fixed plate 41, the speed of the slide 22 is slowed, preventing the frame 201 from quickly contacting the fixing mechanism 30 and affecting processing accuracy.

[0035] Please continue to refer toFigure 1 and Figure 2 The drilling mechanism 30 includes a driving shaft 31, a driven shaft 32 and a transmission shaft 33. Both ends of the transmission shaft 33 are rotatably connected to the rotating shaft 31 and the driven wheel 32 respectively. The drilling mechanism 30 further includes two universal couplings 34 which are respectively connected between the rotating shaft 31 and the transmission shaft 33, and between the driven shaft 32 and the transmission shaft 33, so that the driving shaft 31 and the driven shaft 32 can continuously rotate even if they are not on the same straight line, to meet different performance requirements.

[0036] The drilling mechanism 30 further includes a motor 35 and a first fixing seat 36. The driving shaft 31 passes through the first fixing seat 36 and is rotatably connected to the first fixing seat 36. The first fixing seat 36 is fixed on the surface of the substrate 10 provided with the slide rail 21, and the motor 35 is fixed on the surface of the substrate 10 facing away from the first fixing seat 36 and drives the rotating shaft 31 to rotate by a belt drive method.

[0037] The electronic device housing frame drilling device 100 further includes a base 50 and a plurality of support columns 60. The base 50 and the substrate 10 are arranged opposite to each other at an interval. Both ends of the plurality of support columns 60 are respectively connected to the substrate 10 and the base 50. The motor 35 is clamped between the substrate 10 and the base 60, which on the one hand saves space on the substrate 10, and on the other hand reduces noise and ensures the safety of the motor 35.

[0038] The drilling mechanism 30 further includes a second fixing seat 37 and a drill bit 38. The driven shaft 32 passes through the second fixing seat 37 and is rotatably connected to the second fixing seat 37. The drill bit 38 is fixed to one end of the driven shaft 32 away from the transmission shaft 33, and the drill bit 38 is coaxially arranged with the driven shaft 32. The drill bit 38 is close to the first buffer member 25. The drill bit 38 moves coaxially with the driven shaft 32 under the limitation of the second fixing seat 37. When the frame 201 is driven by the slide plate 22 to approach the drill bit 38, the frame 201 is drilled.

[0039] In this embodiment, the second fixing seat 37 includes an adjusting plate 371 and a connecting plate 372 vertically connected to the adjusting plate 371. The driven shaft 32 passes through the connecting plate 372 and is rotatably connected to the connecting plate 372. A first elongated hole 3711 is formed in the adjusting plate 371, and a second elongated hole 101 is formed in the substrate 10, wherein the second elongated hole 101 is perpendicular to the slide rail 21. The angle between the first elongated hole 3711 and the second elongated hole 101 is adjusted, and a fixing member passes through the first elongated hole 3711 and the second elongated hole 101 to realize the adjustment of the drilling angle.

[0040] During drilling, first, the frame 201 is sleeved on the first fixture 42. Driven by the connecting arm 432, the pressing plate 434 presses the first fixture 42 and the electronic device housing 200 clamped on the first fixture 42. Driven by the cylinder 23, the frame 201 approaches the drill bit 38. After the fixed plate 41 abuts against the first buffer structure 252, the speed is reduced. The frame 201 slowly contacts the drill bit 38 and completes drilling. After drilling, the fixed plate 41 and the frame 201 are driven by the cylinder 23 to separate from and move away from the drill bit 38. Then, the pressing plate 434 is moved away from the first fixture 42 and the frame 201, and the electronic device housing 200 is taken out. This process is repeated in a cycle.

[0041] The drilling device 100 for the electronic device housing frame provided by the present invention realizes drilling of the frame 201 by fixing the fixing mechanism 40 on the slide plate 22 and driving it to approach or move away from the drill bit 38 by the cylinder 23. The frame 201 is clamped on the first fixture 42 and pressed and fixed by the pressing plate 434 of the second fixture 43, which can prevent both deformation and loosening of the frame 201. Both ends of the transmission shaft 33 are rotatably connected to the universal coupling 34, so that the driving shaft 31 and the driven shaft 32 can continuously rotate even if they are not on the same straight line, in order to drill holes at special angles. The drilling device 100 for the electronic device housing frame provided by the present invention has firm clamping, is not easily deformed, has high processing efficiency, and can meet the requirements for holes at special angles.

[0042] The technical features of the above embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0043] The above embodiments only represent the preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
