DETAILED DESCRIPTION

[0029] In order to more clearly illustrate the above-mentioned purposes, features and advantages of the present application, the following will further describe the solutions of the present application. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present application, not all the embodiments.

[0031] The punching device is described below with reference to the drawings.

[0032] As shown in the figure, Figure 1 The punching device comprises a box body 1, and two first through grooves 10 are symmetrically arranged on the box body 1.

[0033] As a possible case, in order to facilitate the maintenance of the transmission shaft 41, a maintenance window can also be arranged on the rear surface of the box body 1.

[0034] The rack 2 is arranged on the box body 1, and two second through grooves 20 are symmetrically arranged on the rack 2 along the height direction.

[0035] It can be understood that the moving direction of the moving mechanism 30 and the first sliding sleeve 31 is perpendicular, which indicates the diversity of the movable direction of the punching mechanism 32.

[0036] The laser positioning mechanism 34 can be inserted into the fixed block 33, and the center line of the light emitted by the laser positioning mechanism 34 coincides with the punching center line of the punching mechanism 32.

[0037] It can be understood that since the center line of the light emitted by the laser positioning mechanism 34 coincides with the punching center line of the punching mechanism 32, the light emitted by the laser positioning mechanism 34 can be used to position the mobile phone accessory to be punched before punching.

[0038] The clamping assembly 4 comprises a first motor 40, a transmission shaft 41 and two symmetrically arranged connecting rod pressing mechanisms 42.

[0039] It should be noted that the first motor 40 described in the embodiment is a reduction motor, so that by controlling the first motor 40 to run slowly, the connecting rod pressing mechanism 42 can be driven to slowly press down, which can increase the safety of operation, reduce the impact and vibration on the mobile phone accessory during clamping, and thus prevent the accessory from being damaged.

[0040] Specifically, the relevant personnel first place the mobile phone accessory to be punched on the box body 1, and control the first motor 40 to run, and the output shaft of the first motor 40 cooperates with the transmission shaft 41 to synchronously drive the two connecting rod pressing mechanisms 42 to slowly press down, thereby stably fixing the mobile phone accessory to be punched below, so as to ensure the stability of the mobile phone accessory to be punched during punching.

[0041] Then, according to the pre-set punching position of the mobile phone accessory to be punched, the moving mechanism 30 and the first sliding sleeve 31 are pushed to move respectively, and the position of the punching assembly 3 is adjusted. This adjustment process can realize the multidirectional movement (lateral movement and longitudinal movement) of the punching assembly 3, so as to realize multidirectional adjustment, ensure the alignment of the punching position, and expand the punching range. The lateral movement is the movement along the rack 2 in the transverse direction, and the longitudinal movement is the movement in the direction perpendicular to the transverse direction in the horizontal plane parallel to the box body 1, that is, the movement along the moving mechanism 30.

[0042] In this process, the laser positioning mechanism 34 helps the operator to monitor in real time whether the punching position is accurately corresponding to the pre-set punching point on the mobile phone accessory to be punched through the emitted light spot. Once it is observed that the light spot emitted by the laser positioning mechanism 34 is completely coincided with the position to be punched on the mobile phone accessory to be punched, the laser positioning mechanism 34 can be removed, and the punching mechanism 32 is controlled to run to punch the mobile phone accessory below. The whole operation process is simple and efficient, and the position of the mobile phone accessory does not need to be frequently adjusted, and the punching precision and efficiency are greatly improved, and the assembly quality of the mobile phone accessory is ensured.

[0043] In one embodiment of the utility model, as shown in Figure 1 The moving mechanism 30 includes a second sliding sleeve 300 and a fixed frame 301. The second sliding sleeve 300 is movably arranged on the rack 2, and the fixed frame 301 is arranged on the second sliding sleeve 300. The fixed frame 301 is arranged in a cross shape with the rack 2 in a staggered manner. The fixed frame 301 is a rectangular frame structure, and the first sliding sleeve 31 is movably arranged in the fixed frame 301.

[0044] Wherein, it can be understood that the lateral position of the punching mechanism 32 can be changed by pushing the second sliding sleeve 300, and the longitudinal position of the punching mechanism 32 can be changed by moving the first sliding sleeve 31, further improving the moving flexibility of the punching mechanism 32, so as to realize flexible adjustment in two-dimensional space, which allows the operator to accurately adjust the position of the punching assembly 3 according to actual needs, ensures the accuracy of punching, and avoids the tediousness of adjusting mobile phone accessories back and forth in the prior art.

[0045] Secondly, the design of the rectangular frame of the fixed frame 301 can provide stable support, so that the first sliding sleeve 31 and the punching assembly 3 remain stable during movement, avoiding affecting the punching effect due to shaking.

[0046] Further, as shown in Figure 2 , the punching device further comprises a first threaded fastener 35, the first threaded fastener 35 is threadedly connected to the second sliding sleeve 300, and one end of the first threaded fastener 35 abuts against the rack 2.

[0047] It should be noted that the first threaded fastener 35 described in this embodiment can be a bolt or a screw, which can be selected according to actual conditions.

[0048] Specifically, after the position of the punching mechanism 32 is determined, the first threaded fastener 35 can be rotated so that the first threaded fastener 35 abuts against the rack 2, thereby further improving the stability of the second sliding sleeve 300 after being fixed on the rack 2, ensuring the accuracy of the punching mechanism 32 when punching, and if the second sliding sleeve 300 needs to be moved, the first threaded fastener 35 only needs to be rotated in the opposite direction again to release the restriction on the second sliding sleeve 300.

[0049] Further, as shown in Figure 2 , the punching device further comprises a second threaded fastener 36, the second threaded fastener 36 is threadedly connected to the first sliding sleeve 31, and one end of the second threaded fastener 36 abuts against the fixed frame 301.

[0050] It should be noted that the second threaded fastener 36 described in this embodiment can be a bolt or a screw, which can be selected according to actual conditions.

[0051] Specifically, after the position of the punching mechanism 32 is determined, the second threaded fastener 36 can be rotated so that the second threaded fastener 36 abuts against the fixed frame 301, thereby further improving the stability of the first sliding sleeve 31 after being fixed, and further ensuring the accuracy of the punching mechanism 32 when punching, and if the first sliding sleeve 31 needs to be moved, the second threaded fastener 36 only needs to be rotated in the opposite direction again to release the restriction on the first sliding sleeve 31.

[0052] In one embodiment of the utility model, as shown in Figure 1 The perforating mechanism 32 includes a telescopic component 320, a second motor 321 and a drill bit 322, wherein the telescopic component 320 is arranged on the lower surface of the first sliding sleeve 31, the telescopic end of the telescopic component 320 is fixedly connected with the second motor 321, and the drill bit 322 is detachably connected with the output shaft of the second motor 321.

[0053] Specifically, the position height of the drill bit 322 can be changed by controlling the telescopic component 320, and the drill bit 322 can be driven to rotate by starting the second motor 321, so that the drill bit 322 simultaneously performs rotation and descending movement, thereby perforating the mobile phone accessory below to be perforated.

[0054] In order to further clearly illustrate the above embodiment, in one embodiment of the application, as shown in Figure 1 The telescopic component 320 is a hydraulic telescopic rod or a pneumatic cylinder.

[0055] Specifically, the telescopic component 320 is a hydraulic telescopic rod or a pneumatic cylinder, which can be selected according to actual conditions, for example, if the telescopic component 320 is a pneumatic cylinder, the position height of the drill bit 322 can be changed by controlling the telescopic end of the pneumatic cylinder to descend by a certain distance, which is simple and convenient to operate.

[0056] In one embodiment of the utility model, as shown in Figure 1 And Figure 5 The laser positioning mechanism 34 includes a mounting bracket 340 and a laser emitter 341, wherein the mounting bracket 340 can be inserted into the first insertion hole 330 or the second insertion hole 331 formed in the fixed block 33, wherein the first insertion hole 330 is parallel to the box body 1, and the second insertion hole 331 is perpendicular to the box body 1.

[0057] When the mounting bracket 340 is inserted into the first insertion hole 330, the center line of the light emitted by the laser emitter 341 coincides with the perforating center line of the perforating mechanism 32, and when the mounting bracket 340 is inserted into the second insertion hole 331, the laser emitter 341 is parallel to the box body 1.

[0058] Specifically, by inserting the mounting bracket 340 into the first insertion hole 330 or the second insertion hole 331, different relative position relationships between the laser emitter 341 and the perforating mechanism 32 can be established, when the mounting bracket 340 is inserted into the first insertion hole 330, the light center line of the laser emitter 341 coincides with the perforating center line of the perforating mechanism 32, and the relative position relationship between the perforating mechanism 32 and the perforating position on the mobile phone accessory can be more directly and accurately reflected by using laser positioning, so as to ensure the accuracy of subsequent perforation, reduce the error of human visual observation, and improve the working quality and reliability.

[0059] When the mounting frame 340 is plugged into the second insertion hole 331, the laser emitter 341 is parallel to the box 1, so that the laser emitter 341 can be away from the drill bit 322, thereby not affecting the falling stroke of the drill bit 322.

[0060] By means of a simple plugging operation, the relative position relationship between the laser emitter 341 and the punching mechanism 32 can be changed, the operation is flexible and simple, and the design that the first insertion hole 330 is parallel to the box 1 can ensure that, when the mounting frame 340 is inserted into the first insertion hole 330, parallelism with the box 1 is achieved, and the situation that the light emitted by the laser emitter 341 is deflected is avoided.

[0061] In an embodiment of the present application, as shown in Figure 1 The mounting frame 340 is in the shape of a "H".

[0062] It can be understood that, by virtue of the design that the mounting frame 340 is in the shape of a "H", the punching mechanism 32 can be avoided, so that collision with the punching mechanism 32 is avoided, and the light center line of the laser emitter 341 is ensured to be accurately coincident with the punching center line of the punching mechanism 32.

[0063] In an embodiment of the present application, as shown in Figure 3 and Figure 4 The connecting rod downward pressing mechanism 42 comprises a first connecting rod 420, a second connecting rod 421, a mounting block 422 and a pressing plate 423, wherein one end of the first connecting rod 420 is fixedly connected with the transmission shaft 41, the other end of the first connecting rod 420 penetrates through the first through slot 10 and is hingedly connected with the second connecting rod 421, one end of the second connecting rod 421 away from the first connecting rod 420 is hingedly connected with the mounting block 422, the mounting block 422 is slidingly connected in the second through slot 20, and the pressing plate 423 is detachably connected on the mounting block 422.

[0064] It can be understood that, by virtue of the second through slot 20, the mounting block 422 can be limited, so that the mounting block 422 can drive the pressing plate 423 to vertically move up and down.

[0065] Specifically, when the first motor 40 is started, the output shaft of the first motor 40 drives the first connecting rod 420 to rotate through the driving transmission shaft 41, and along with the rotation of the first connecting rod 420, the second connecting rod 421 synchronously rotates. This series of linkage actions make the mounting block 422 move vertically downwards along the second through slot 20, thereby driving the pressing plate 423 to gradually press on the mobile phone accessory, so as to ensure the stability of the mobile phone accessory when punching.

[0066] In order to further clearly illustrate the above embodiment, in an embodiment of the present application, the pressing plate 423 is made of rubber.

[0067] Wherein, it can be understood that the excellent elasticity and buffering performance of the rubber material can provide certain buffering when the mobile phone accessory is compressed, reduce stress concentration caused by direct compression, thereby protecting the mobile phone accessory from damage, and the surface of the rubber material generally has certain roughness, which can increase the friction between the mobile phone accessory and improve the stability of the pressing plate 423 during compression, ensuring the stability of the mobile phone accessory during punching.

[0068] In summary, the punching device can quickly realize multi-directional adjustment of the punching mechanism, expand the punching range, avoid the tedious back-and-forth adjustment of the mobile phone accessory, and also accurately point to the position to be punched on the mobile phone accessory for positioning, greatly increasing the accuracy of punching and ensuring the assembly quality of the subsequent mobile phone accessory.
