[0004] However, the device cannot adjust the cutting size and angle. If fingerprint chips of different sizes and shapes are required, different devices need to be replaced, which is very inconvenient and will also affect the overall production efficiency of the fingerprint chip. Therefore, a fingerprint chip cutting device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 In this embodiment, a fingerprint chip cutting device includes a box body 1, the inner top wall of the box body 1 is provided with a cutting component 2 capable of cutting the chip, and the inner bottom wall of the box body 1 is provided with a fixing device 3 capable of maintaining cutting stability and improving cutting effect.

[0024] In addition, the cutting assembly 2 includes a fixed seat 201 fixed to the inner top wall of the box body 1, and four electric push rods 202 are fixed to the bottom of the fixed seat 201. The four electric push rods 202 have an inherent laser cutter 203 on the side opposite to each other. The provision of four electric push rods 202 can improve the stability of the laser cutter 203, thereby improving the cutting accuracy. At the same time, the four electric push rods 202 can realize the movement of the laser cutter 203 in the front, back, left and right directions to achieve cutting.

[0025] In this embodiment, the fingerprint chip is fixed by the fixing device 3, and the stability of the laser cutter 203 is improved in conjunction with the four electric push rods 202, thereby ultimately achieving high-quality cutting of the fingerprint chip.

[0026] Please refer again Figure 1 and Figures 2 to 4In order to achieve the cutting size, the fixing device 3 in this embodiment includes a base 301 fixed to the inner bottom wall of the box body 1, and a rotating mechanism 302 capable of rotating the chip is provided on the inner side of the base 301. The top of the base 301 is provided with a stabilizing mechanism 303 capable of ensuring the chip fixing effect.

[0027] In addition, the rotating mechanism 302 includes a servo motor 3021 fixed to the inner wall of the base 301, and the output shaft of the servo motor 3021 is fixed with an active rod 3022, and the outer surface of the active rod 3022 is fixed with a driving gear 3023. The power of the servo motor 3021 can be transmitted through the rotation of the driving gear 3023. The active rod 3022 extends to the outside of the top wall of the base 301, and a sealed bearing is fixed on the outer surface of the active rod 3022 and located on the outside of the base 301. The active rod 3022 is rotatably connected to the base 301 through the sealed bearing. While the sealed bearing ensures the rotational stability of the active rod 3022, the base 301 and the active rod 3022 can also be separated in motion. Providing a sealed bearing on the outside of the base 301 can reduce the height of the base 301, thereby promoting heat dissipation.

[0028] It should be further explained that the driving gear 3023 is meshed with the driven gear 3032, and a fixing bracket is fixed to the outer surface of the servo motor 3021. The servo motor 3021 is fixed to the inner side of the base 301 through the fixing bracket. The driving gear 3023 and the driven gear 3032 are meshed with each other, which can promote the smooth transmission of power of the servo motor 3021, ensure the accuracy of rotation, and improve the cutting quality of the fingerprint chip.

[0029] It can be known that the stabilizing mechanism 303 includes a connecting bearing 3031 rotatably connected to the top of the base 301, a driven gear 3032 is fixed to the top of the connecting bearing 3031, a stabilizing platform 3033 is fixed to the top of the driven gear 3032, a micro motor 3034 is fixed to the inner side of the stabilizing platform 3033, two transmission components 3035 are fixed to the outer surface of the output shaft of the micro motor 3034, and a rotating rod 3036 is fixed on the opposite sides of the two transmission components 3035, two outer shells 3037 are fixed to the top of the stabilizing platform 3033, and a fixing splint 3038 is fixed to the inner side of the outer shell 3037. The micro motor 3034 can reduce the overall height of the stabilizing mechanism 303, thereby reducing the height of the box body 1, making the box body 1 as a whole compact and easy to place. The arrangement of the transmission component 3035 can realize long-distance transmission.

[0030] It should be noted that each transmission assembly 3035 includes a driving wheel, a driven wheel and a conveyor belt. Each driving wheel is fixed to the output shaft of the micro motor 3034, and the two driven wheels are fixed to the outer surfaces of the two rotating rods 3036. Each rotating rod 3036 extends to the outside of the outer shell 3037. The outer surface of each rotating rod 3036 is threadedly connected to a movable splint 3039. The arrangement of two transmission assemblies 3035 can simultaneously output the power of the micro motor 3034 to the two rotating rods 3036, prompting the two movable splints 3039 to run simultaneously.

[0031] In addition, each transmission assembly 3035 includes a driving wheel, a driven wheel and a conveyor belt. Each driving wheel is fixed to the output shaft of the micro motor 3034, and the two driven wheels are fixed to the outer surfaces of the two rotating rods 3036. Power is transmitted between the driving wheel and the driven wheels through the conveyor belt. The use of the conveyor belt can achieve long-distance transmission and reduce the overall weight, and can also transmit power to the two rotating rods 3036 at the same time, causing the two rotating rods 3036 to rotate at the same time, thereby increasing the fixing effect of the movable splint 3039.

[0032] In this embodiment, the power is outputted by the rotating mechanism 302, and the driven gear 3032 is driven to rotate via the driving gear 3023, which further causes the transmission assembly 3035 to rotate as a whole, thereby achieving cutting at different angles.

[0033] It can be understood that by cooperating with the cutting assembly 2 and the rotating mechanism 302, the cutting of fingerprint chips of different sizes and shapes can be achieved, and then by cooperating with the four electric push rods 202 and the stabilizing mechanism 303, the cutting process is ensured to be smooth, thereby further improving the accuracy of fingerprint chip cutting.

[0034] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0035] The working principle of the above embodiment is:

[0036] The chip is placed on the two fixed splints 3038 and the micro motor 3034 is started at the same time. The power of the micro motor 3034 is transmitted to the two rotating rods 3036 through the two transmission components 3035, causing the two rotating rods 3036 to rotate at the same time. Due to the limit of the movable splint 3039 by the shell 3037 and the rotation of the rotating rod 3036, the two movable splints 3039 are simultaneously close to the fixed splint 3038 to fix the fingerprint chip, thereby ensuring the fixing effect of the fingerprint chip. If the fingerprint chip needs to be rotated, the servo motor 3021 is started. The servo motor 3021 causes the driving gear 3023 to rotate, further driving the driven gear 3032 to rotate, thereby rotating the fingerprint chip fixed between the two shells 3037. After the preparation is completed, the laser cutter 203 is driven by the four electric push rods 202 to cut the fingerprint chip. The device can arbitrarily adapt the size and shape of the fingerprint chip to be cut according to specific needs, can adapt to different needs, improve the production efficiency of fingerprint chips, and reduce production costs.
