Description

Technical Field

[0001] This invention relates to the field of punching technology for 3C product casings, specifically a punching device for processing 3C product casings. Background Technology

[0002] 3C products are a combination of computers, communications, and consumer electronics, also known as information appliances. Mobile phones are a common type of 3C product. Their casings are mostly made of metal and are formed by casting. During the manufacturing process of metal mobile phone casings, it is necessary to place a rear camera. Therefore, a punching device is needed to punch holes of different sizes in the metal mobile phone casing so that the rear camera can be placed during subsequent assembly.

[0003] Existing punching devices are not suitable for punching metal phone casings of varying thicknesses or widths. They cannot simultaneously pre-press and fix the sides and top of the casing, resulting in poor fixing. This causes the casing to easily shift during punching. Furthermore, it is difficult to quickly select and use different sizes of drill bits. Existing devices require repeated handling, installation, and removal of different drill bits for replacement, which reduces punching efficiency. Therefore, improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a punching device for processing 3C product casings. This device can simultaneously clamp and fix mobile phone casings of different thicknesses and widths during punching operations, and can simultaneously pre-press and fix the top and sides of the casing, ensuring the casing is more firmly and stably positioned on the base, preventing displacement during punching. Furthermore, it can quickly select and use different specifications of drill bits according to the actual punching situation, improving punching efficiency and avoiding the need to repeatedly change and retrieve different specifications of drill bits, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a punching device for processing the casing of 3C products, comprising a base, a support rod, a top plate and a mobile phone casing, wherein the top plate is connected to the base via the support rod, two side plates are fixedly installed on the base, and the mobile phone casing is placed between the two side plates, and the side plates are provided with pressing components for pre-pressing and fixing the sides and top of the mobile phone casing;

[0006] The base has a placement groove in the middle, and a material slag receiving component is slidably arranged in the placement groove. A motor is slidably arranged on the top plate, and a rotating shaft is fixedly connected to the output end of the motor. A punching adjustment component is provided on the rotating shaft.

[0007] By adopting the above technical solution, the pressing component can simultaneously clamp and fix the side and top of the phone casing during the punching operation, making the phone casing more firmly and stably positioned on the base and preventing the phone casing from shifting during punching. The slag receiving component can collect the debris and residue generated during the punching process. And by setting the punching adjustment component, different specifications of drill bit barrels can be quickly selected according to the actual punching situation, improving punching efficiency and avoiding the need to repeatedly change and pick up different specifications of drill bit barrels.

[0008] Preferably, the pressing component includes a first strip groove and a second strip groove, which are sequentially formed on the side plate. A plurality of first springs are provided in the first strip groove, and a movable plate is connected to the end of each first spring. A pressing component is provided on the movable plate. A plurality of second springs are provided in the second strip groove, and a clamping plate for clamping and fixing the side of the mobile phone casing is connected to the end of each second spring. A side U-shaped rod is provided on the side plate, and both ends of the side U-shaped rod pass through the first strip groove and the second strip groove, respectively, and are connected to the movable plate and the clamping plate, respectively.

[0009] By adopting the above technical solution, when the mobile phone casing is pressed into contact with the base, under the action of the first spring and the second spring, the moving plate and the clamping plate can be pushed out of the side plate. After the moving plate extends out of the side plate, under the action of the pressing component, it can press and fix the top of the mobile phone casing. After the clamping plate extends out of the side plate, it can clamp and fix the side of the mobile phone casing, so that the mobile phone casing can be more firmly and stably placed on the base.

[0010] Preferably, the pressing component includes a third strip groove formed at the bottom of the moving plate, a plurality of third springs are provided in the third strip groove, and the ends of the third springs are connected to a pressing plate for pressing and fixing the top of the mobile phone casing.

[0011] By adopting the above technical solution, when the moving plate extends out of the side plate, under the action of the third spring, it can push the pressure plate to press and fix the top of the phone shell, and with the clamping plate to clamp the side of the phone shell, it can clamp and fix phone shells of different thicknesses and widths, and the fixing effect is more firm and stable.

[0012] Preferably, the top edge of the movable plate and the edge of the clamping plate near the side plate are provided with arc-shaped guide surfaces.

[0013] By adopting the above technical solution, when punching holes in the phone casing is required, the phone casing is placed between two movable plates, and then the phone casing is pressed down. Since the top of the movable plate has an arc-shaped surface, the downward movement of the phone casing will overcome the elastic force of the first spring and push the movable plate to retract into the first slot. Under the action of the side U-rod, the clamping plate will also be pulled to retract into the second slot. Since the lower pressure plate also has an arc-shaped guide surface, during the process of the movable plate retracting into the first slot, the opening of the first slot will squeeze the arc-shaped guide surface on the lower pressure plate, thereby causing the lower pressure plate to retract into the third slot. When the phone casing moves to contact the base, under the action of the first and second springs, the movable plate and clamping plate are pushed out of the side plate. After the movable plate extends out of the side plate, under the action of the third spring, the lower pressure plate is pushed out of the third slot and pressed and fixed on the top of the phone casing. It can clamp and fix phone casings of different thicknesses and widths at the same time, and can pre-press and fix the top and sides of the phone casing at the same time, so that the phone casing can be more firmly and stably placed on the base.

[0014] Preferably, two grooves are symmetrically formed on the upper surface of the base, and several fourth springs are provided in the grooves. The ends of the fourth springs are connected to push plates, which are used to push the mobile phone casing upward.

[0015] By adopting the above technical solution, when it is necessary to remove the punched mobile phone casing, the side U-shaped rod first overcomes the elastic force of the first and second springs, pulling the moving plate and clamping plate into the first and second slots respectively. At the same time, the lower pressure plate retracts into the third slot, releasing the pressure and fixation on the mobile phone casing. Then, under the action of the fourth spring, the push plate pushes the mobile phone casing upward, thus facilitating the removal of the punched mobile phone casing.

[0016] Preferably, the slag receiving assembly includes a receiving frame that is slidably disposed in the placement trough, and a magnetic plate is provided at the bottom of the inner wall of the receiving frame.

[0017] By adopting the above technical solution, the receiving frame can collect the debris and residue generated during the punching process. Since most existing mobile phone casings are made of metal, the magnetic plate allows the debris and residue to be better located at the bottom of the receiving frame, preventing debris from splashing. At the same time, the magnetic plate can also exert a certain attraction force on the metal mobile phone casing, allowing the mobile phone casing to be better positioned on the base.

[0018] Preferably, a rectangular slide rod is fixedly connected to the top of the motor, and a battery for providing power to the motor is provided on the rectangular slide rod 20. A through slot is provided on the top plate for the rectangular slide rod to move along the width direction of the top plate. A baffle is fixedly connected to the top of the rectangular slide rod. A friction plate is slidably sleeved on the rectangular slide rod. A telescopic spring is sleeved on the rectangular slide rod. The two ends of the telescopic spring are respectively connected to the baffle and the friction plate. A handle is fixedly connected to the friction plate.

[0019] By adopting the above technical solution, when the motor is in the appropriate position, the punching process of the mobile phone shell is as follows: the motor is started, the motor drives the rotating shaft and the punching adjustment component to rotate, and then overcomes the elastic force of the telescopic spring, presses down the baffle, and drives the rectangular slide rod and the motor to move down, so that the punching adjustment component can perform punching operation on the mobile phone shell.

[0020] Preferably, a limiting plate located below the top plate is fixedly sleeved on the rectangular slide rod, and the limiting plate is provided with a plurality of ball bearings for reducing the friction between the limiting plate and the top plate.

[0021] By adopting the above technical solution, when it is necessary to change the position of the motor, the elastic force of the telescopic spring is overcome, and the friction plate is pulled upward by the handle rod, so that the friction plate and the top plate are separated from each other. Since the ball bearing is provided on the limiting plate, the friction between the limiting plate and the top plate is reduced, which makes it easier to push the rectangular slide rod to move along the through groove, thereby changing the position of the motor.

[0022] Preferably, the punching adjustment assembly includes a first drill barrel, a second drill barrel, and a third drill barrel. The first drill barrel is sleeved on the rotating shaft, the second drill barrel is sleeved on the first drill barrel, and the third drill barrel is sleeved on the second drill barrel. The top ends of the first drill barrel, the second drill barrel, and the third drill barrel are respectively fixedly connected to a first connecting plate, a second connecting plate, and a third connecting plate with rectangular slots. The rotating shaft is provided with three positioning components for fixing the first connecting plate, the second connecting plate, and the third connecting plate.

[0023] Preferably, the positioning component includes a threaded post fixedly connected to the rotating shaft, the threaded post passing through a first connecting plate, a second connecting plate, or a third connecting plate, and a nut threadedly connected to the threaded post.

[0024] By adopting the above technical solution, when different drill bits are needed to punch holes in the phone casing, the user loosens the nut on the corresponding connecting plate of the desired drill bit, then pushes the connecting plate down, causing the desired drill bit to move down as well. The user then observes whether the desired drill bit is at the bottom. If not, the user loosens the nut corresponding to the bottom-positioned drill bit and pushes it up, bringing it to the bottom. For example, when using a second drill bit, the user loosens the nut on the second connecting plate to release its fixation, then pushes the second connecting plate down, causing the second drill bit to move down. The user then observes whether the second drill bit is at the bottom; it is clearly not. The user then loosens the nut on the third connecting plate and pushes it up, causing the third drill bit to move up. Therefore, different drill bit specifications can be quickly selected based on the actual punching situation, improving punching efficiency and avoiding the need to repeatedly change and retrieve different drill bit specifications.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. Through the arrangement of the first spring, the moving plate, the second spring, the clamping plate, the third spring, the lower pressure plate, and the side U-shaped rod, when the mobile phone casing moves to contact the base, under the action of the first and second springs, the moving plate and the clamping plate are pushed out of the side plate. After the moving plate extends out of the side plate, under the action of the third spring, the lower pressure plate is pushed out of the third slot and presses and fixes the top of the mobile phone casing. After the clamping plate extends out of the side plate, it can clamp and fix the side of the mobile phone casing. That is, it can clamp and fix the top and side of mobile phone casings of different thicknesses and widths, so that the mobile phone casing can be more firmly and stably placed on the base.

[0027] Second, by setting up the receiving frame and the magnetic plate, the receiving frame can collect the debris and residue generated during the punching process. Since most existing mobile phone shells (the outer shell of the mobile phone itself, not the protective shell) are made of metal, the setting of the magnetic plate allows the debris and residue to be better located at the bottom of the receiving frame, avoiding the splashing of debris. At the same time, the magnetic plate can also exert a certain attraction force on the metal mobile phone shell, so that the mobile phone shell can be better placed on the base.

[0028] Third, with the setting of the fourth spring and the push plate, when the pressure plate and clamping plate release the pressure and fixation on the mobile phone shell, under the action of the elastic force of the fourth spring, the push plate pushes the mobile phone shell upward, thereby making it easier to remove the punched mobile phone shell.

[0029] IV. Using a drill barrel, a second drill barrel, a third drill barrel, a first connecting plate, a second connecting plate, a third connecting plate, a threaded post, and a nut, when different drill barrels are needed to punch holes in the phone casing, loosen the nut on the corresponding connecting plate according to the drill barrel you need to use, then push the connecting plate down, moving the drill barrel you need to use down as well. Observe whether the drill barrel you need to use is at the bottom. If not, loosen the nut corresponding to the drill barrel at the bottom and push the drill barrel at the bottom up so that the drill barrel you need to use is at the bottom. Therefore, different specifications of drill barrels can be quickly selected according to the actual punching situation, improving punching efficiency and avoiding the need to change and pick up different specifications of drill barrels.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1 to 5 The present invention provides a technical solution: a punching device for processing the shell of 3C products, including a base 1, a support rod 2, a top plate 3 and a mobile phone shell 4. The top plate 3 is connected to the base 1 through the support rod 2. Two side plates 5 are fixedly installed on the base 1, and the mobile phone shell 4 is placed between the two side plates 5. The side plates 5 are provided with a pressing component for pre-pressing and fixing the sides and top of the mobile phone shell 4.

[0038] The pressing component includes a first strip groove and a second strip groove, which are sequentially formed on the side plate 5. Several first springs 8 are arranged in the first strip groove, and the ends of the first springs 8 are connected to a movable plate 9. Arc-shaped guide surfaces 15 are provided at the top edge of the movable plate 9 and at the edge of the clamping plate 11 near the side plate. A pressing component is provided on the movable plate 9. Several second springs 10 are arranged in the second strip groove, and the ends of the second springs 10 are connected to a clamping plate 11 for clamping and fixing the side of the mobile phone casing 4. A side U-shaped rod 12 is provided on the side plate 5. The two ends of the side U-shaped rod 12 pass through the first strip groove and the second strip groove respectively, and are connected to the movable plate 9 and the clamping plate 11 respectively.

[0039] When the phone case 4 is pressed into contact with the base, the first spring 8 and the second spring 10 can push the moving plate 9 and the clamping plate 11 to extend out of the side plate. After the moving plate 9 extends out of the side plate 5, it can press and fix the top of the phone case 4 under the action of the pressing component. After the clamping plate 11 extends out of the side plate 5, it can clamp and fix the side of the phone case 4, so that the phone case 4 can be more firmly and stably placed on the base 1.

[0040] The pressing component includes a third strip groove at the bottom of the movable plate 9, and a plurality of third springs 13 are provided in the third strip groove. The ends of the third springs 13 are connected to a pressing plate 14 for pressing and fixing the top of the mobile phone casing 4.

[0041] When punching holes in the phone casing 4 is required, the phone casing 4 is placed between the two movable plates 9, and then the phone casing 4 is pressed down. Because the top of the movable plate 9 has an arc-shaped surface, the downward movement of the phone casing 4 overcomes the elastic force of the first spring 8, pushing the movable plate 9 to retract into the first slot. Under the action of the side U-shaped rod 12, it also pulls the clamping plate 11 to retract into the second slot. Because the lower pressure plate 14 also has an arc-shaped guide surface, during the process of the movable plate 9 retracting into the first slot, the opening of the first slot will press against the arc-shaped guide surface on the lower pressure plate 14, thereby... The lower pressure plate 14 retracts into the third slot. When the phone case 4 moves to contact the base 1, under the action of the first spring 8 and the second spring 9, the moving plate 9 and the clamping plate 11 are pushed out of the side plate 5. After the moving plate 9 extends out of the side plate 5, under the action of the third spring 13, the lower pressure plate 14 is pushed out of the third slot and pressed and fixed on the top of the phone case 4. It can clamp and fix phone cases 4 of different thicknesses and widths at the same time, and can pre-press and fix the top and sides of the phone case 4 at the same time, so that the phone case 4 can be more firmly and stably placed on the base 1.

[0042] Two grooves are symmetrically formed on the upper surface of the base 1. Several fourth springs 16 are set in the grooves. The ends of the fourth springs 16 are connected to push plates 17, which are used to push the mobile phone casing 4 to move upward.

[0043] When it is necessary to remove the punched phone casing 4, the side U-shaped rod 12 first overcomes the elastic force of the first spring 8 and the second spring 10, pulling the moving plate 9 and the clamping plate 11 into the first and second slots respectively. At the same time, the lower pressure plate 14 retracts into the third slot, releasing the pressure and fixation on the phone casing 4. Then, under the action of the elastic force of the fourth spring 16, the push plate pushes the phone casing 4 upward, thus facilitating the removal of the punched phone casing 4.

[0044] A placement groove is provided in the middle of the base 1, and a slag receiving component is slidably arranged in the placement groove. The slag receiving component includes a receiving frame 18 slidably arranged in the placement groove. A magnetic plate 19 is provided at the bottom of the inner wall of the receiving frame 18. The receiving frame 18 can collect the debris and residue generated during the punching process. Since most of the existing mobile phone shells 4 are made of metal, the setting of the magnetic plate 19 allows the debris and residue to be better located at the bottom of the receiving frame 18, avoiding the splashing of debris. At the same time, the magnetic plate 19 can also exert a certain attraction force on the metal mobile phone shell 4, so that the mobile phone shell 4 can be better placed on the base 1.

[0045] A plurality of rubber support pillars are provided on the upper surface of the magnet plate 19. The top of each rubber support pillar has a spherical concave surface, and the spherical convex surface abuts against the lower surface of the mobile phone casing. The rubber support pillars and the punching adjustment assembly are staggered to prevent punching interference. Preferably, a plurality of rubber support pillars are provided on the lower periphery of the punching adjustment assembly in a uniformly distributed manner.

[0046] The spherical concave surface forms a suction cup-like effect after contacting the lower surface of the phone casing, making the phone casing more stable. At the same time, it can also provide flexible support to prevent large deformation of the phone casing caused by stamping.

[0047] A motor 6 is slidably mounted on the top plate 3. A rotating shaft 7 is fixedly connected to the output end of the motor 6. A rectangular slide rod 20 is fixedly connected to the top of the motor 6. A battery for providing power to the motor is mounted on the rectangular slide rod 20.

[0048] A fixed plate 36 with a through hole is fixedly connected to the motor 6. A T-shaped rod 37 is slidably connected inside the through hole. An air collecting ring 38 is fixedly connected to the bottom end of the T-shaped rod 37. Several air holes are opened on the inner side of the air collecting ring 38. A retaining ring 39 is fixedly sleeved on the T-shaped rod 37. A thrust spring 40 is sleeved on the T-shaped rod 37. The two ends of the thrust spring 40 are respectively connected to the fixed plate 36 and the retaining ring 39. A vacuum cleaner 41 is fixedly connected to the fixed plate 36. The air inlet of the vacuum cleaner 41 is connected to the air collecting ring 38 through a connecting pipe 42.

[0049] When punching holes in the phone casing 4, the air collecting ring 38 will first come into contact with the phone casing 4. As the motor 6 moves downward, under the action of the spring force of the thrust spring 40, it will push the air collecting ring 38 to keep in contact with the phone casing 4. When the vacuum cleaner 41 is started, the debris generated by punching will enter the air collecting ring 38 through the air hole, and then enter the vacuum cleaner 41 through the connecting tube 42 to collect the debris generated by punching. This makes the surface of the phone casing 4 clean and tidy after punching, avoiding manual cleaning.

[0050] The top plate 3 has a through groove 21 for the rectangular slide rod 20 to move along the width of the top plate 3. A baffle 22 is fixedly connected to the top of the rectangular slide rod 20. A friction plate 24 is slidably sleeved on the rectangular slide rod 20. A telescopic spring 25 is sleeved on the rectangular slide rod 20. The two ends of the telescopic spring 25 are respectively connected to the baffle 22 and the friction plate 24. A handle 26 is fixedly connected to the friction plate 24. A limiting plate 27 located below the top plate 3 is fixedly sleeved on the rectangular slide rod 20. Several balls 28 are provided on the limiting plate 27 to reduce the friction between the limiting plate 27 and the top plate 3.

[0051] Once the motor 6 is in the appropriate position, the punching process for the phone casing 4 is as follows: the motor 6 is started, and the motor 6 drives the rotating shaft 7 and the punching adjustment component to rotate. Then, overcoming the elastic force of the telescopic spring 25, the baffle 22 is pressed down, which drives the rectangular slide bar 20 and the motor 6 to move down, so that the punching adjustment component can perform the punching operation on the phone casing 4.

[0052] When it is necessary to change the position of the motor 6, the friction plate 24 is pulled upward by the handle 26 to overcome the elastic force of the telescopic spring 25, so that the friction plate 24 is separated from the top plate 3. Since the ball bearing 28 is provided on the limiting plate 27, the friction between the limiting plate 27 and the top plate 3 is reduced, which makes it easier to push the rectangular slide bar 20 to move along the through groove 21, thereby changing the position of the motor 6.

[0053] The rotating shaft 7 is equipped with a punching adjustment assembly, which includes a first drill barrel 29, a second drill barrel 30, and a third drill barrel 31. The first drill barrel 29 is sleeved on the rotating shaft 7, the second drill barrel 30 is sleeved on the first drill barrel 29, and the third drill barrel 31 is sleeved on the second drill barrel 30. The top ends of the first drill barrel 29, the second drill barrel 30, and the third drill barrel 31 are respectively fixedly connected to a first connecting plate 32, a second connecting plate 33, and a third connecting plate 34 with rectangular slots. The rotating shaft 7 is equipped with three positioning components for fixing the first connecting plate 32, the second connecting plate 33, and the third connecting plate 34. The positioning components include threaded posts 35 fixedly connected to the rotating shaft 7. The threaded posts 35 penetrate the first connecting plate 32, the second connecting plate 33, or the third connecting plate 34. Nuts 36 are threadedly connected to the threaded posts 35.

[0054] When different drill bits are needed to punch holes in the phone casing 4, loosen the nut 23 on the corresponding connecting plate according to the drill bit you need. Then push the connecting plate down, moving the drill bit down as well. Observe whether the drill bit is at the bottom. If not, loosen the nut 23 corresponding to the bottom drill bit and push the bottom drill bit up until it is at the bottom. For example, when the second drill bit 30 is needed, loosen the nut 23 on the second connecting plate 33 to release the fixation of the second connecting plate 33. Then push the second connecting plate 33 to move the second drill bit 30 down. Observe whether the second drill bit 30 is at the bottom. Figure 5 It is clear that this is not the case. Then, loosen the nut 23 on the third connecting plate 34 and push the third connecting plate 34 to move the third drill barrel 31 upward. Therefore, different specifications of drill barrels can be quickly selected according to the actual punching situation, which improves punching efficiency and avoids having to change and pick up different specifications of drill barrels.

[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
