Description

Technical Field

[0001] This application belongs to the technical field of chip packaging and testing, and particularly relates to a punching device for smart card chips. Background Art

[0002] A smart card chip is a relatively small chip that can be used in cards such as bus cards and bank cards. Before leaving the factory, the smart card chip needs to be tested for its functions and electrical properties. A smart card testing device is a device for testing the functions and electrical properties of smart card chips. When the testing unit of the smart card testing device screens out unqualified smart card chips, its punching device punches and scraps the unqualified smart card chips, which is convenient for quickly distinguishing the quality of smart card chips in the subsequent production process. Due to the high frequency of use and large punching force of the punching device of the smart card testing device, the punching die often gets damaged under high-load working conditions, thus reducing the production efficiency.

[0019] To make the purpose, technical solutions and advantages of the implementation of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.

[0020] As Figures 1 to 4 shown, the punching device provided by the present application includes a housing 1, a power device 2, a punch pin 3, a female die mounting seat 4 and a punching female die 5.

[0021] The housing 1 is used to fixedly install the power device 2, the punch pin 3, the female die mounting seat 4, etc. It is generally U-shaped as a whole, so as to form a punching working space inside the U-shape. The punch pin 3 and the punching female die 5 are vertically arranged opposite to each other in the punching working space for punching the smart card chip 6.

[0022] The power device 2 is a device such as a cylinder, a hydraulic cylinder or a linear motor. It is installed and fixed on the housing 1. The power device 2 is fixedly connected to the punch pin 3 for controlling the relative movement of the punch pin 3.

[0023] The female die mounting seat 4 is a stepped disc structure and is fixed to the lower side within the punching working space of the housing 1. A circular hole is provided in the center of the female die mounting seat 4, and the punching female die 5 is arranged in this central circular hole. The punching female die 5 is locked in the central circular hole through the cooperation of a radial threaded hole 41 provided on the outer surface of the disc and a screw.

[0024] The punching female die 5 includes an outer sleeve 51 and a female die fixing rod 52. The outer sleeve 51 is in a circular ring shape and is provided with a threaded limit hole 511 thereon. The outer sleeve 51 is sleeved on the upper outer side of the female die fixing rod 52, and the outer sleeve 51 and the female die fixing rod 52 are fixed into an integral structure through a screw arranged in the threaded limit hole 511. An punching hole 523 is provided inside the female die fixing rod 52, and the axis of the punching hole 523 is collinear with the axis of the punch pin 3. The outer surface of the upper end of the female die fixing rod 52 is configured into a conical structure 522. By changing the structure of the upper end of the female die fixing rod 52 from circular to conical, the overall impact resistance of the die can be effectively improved, thereby effectively reducing the damage of the punch pin 3 to the female die fixing rod 52 and preventing the female die fixing rod 52 from cracking due to long-term stress. At the same time, when the female die fixing rod 52 is damaged during the long-term cooperation with the punch pin 3, only the female die fixing rod 52 needs to be replaced, which can make the replacement cost of the punching female die 5 lower.

[0025] Furthermore, in this application, the inner surface of the punching hole 523 and the surface of the conical structure 522 of the female die fixing rod 52 are polished, effectively improving the contact surface accuracy with the punch pin 3, reducing burrs, reducing the friction strength between the punch pin 3 and the punching female die 5, and improving the overall service life of the punch pin 3 and the punching female die 5.

[0026] Furthermore, in this application, a side cutting surface 521 (for example, this side cutting surface can be a 5mm×3mm area) is provided on one side of the female die fixing rod 52. Correspondingly, a plane adapted to the side cutting surface 521 is provided on the inner surface of the central through hole of the female die mounting seat 4. The quick positioning of the punching female die 5 and the female die mounting seat 4 is realized through the cooperation of the side cutting surface 521 of the female die fixing rod 52 and the inner hole plane of the female die mounting seat 4. At the same time, the side cutting surface is more conducive to the fixing screw to firmly lock the female die fixing rod 52, preventing the punching female die 5 from loosening during the punching process, resulting in die damage and product failure.

[0027] The punching device provided by this application can effectively punch unqualified smart card chips and can avoid the punching female die from being damaged due to frequent work, thereby improving production efficiency.

[0028] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in this application should be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claimed rights.
