DETAILED DESCRIPTION

[0023] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0024] As shown in Figure 1 , the terminal described in the present application is formed by injection molding one or more pins 11, so that the pins 11 are wrapped by the injection molded shell of a specific shape. One end of the pin 11 is exposed outside the injection molded structure, and the other part is wrapped inside the injection molded structure.

[0025] The connection of the terminal with other electrical equipment is essentially the process that a certain reference surface 12 on the terminal abuts against the electrical equipment while the pin 11 is electrically connected with the interface in the electrical equipment. Therefore, the distance between the end of the pin 11 and the reference surface 12, i.e. the length of the pin 11 exposed outside the reference surface 12, is an important dimension for product quality control.

[0026] The content of the present application will be further described in detail below in combination with specific embodiments:

[0027] In combination Figure 2 and Figure 3 , a terminal size detection device is provided, which comprises a base 2, and a jig 3 and a distance measuring unit 4 are arranged on the base 2.

[0028] The jig 3 is fixed on the base 2, and the upper surface of the jig 3 is provided with a loading cavity 31 shaped according to the terminal. The terminal to be detected is placed in the loading cavity 31 under the driving of a transfer device. A pressing plate 51 is arranged above the loading cavity 31, and the pressing plate 51 is driven to move up and down by a pressing plate driving mechanism 52, and can abut against the terminal, so that the terminal is tightly matched with the loading cavity 31.

[0029] The distance measuring unit 4 comprises a laser 41, which is slidably connected with the base 2 through a distance measuring transfer mechanism 42. In actual use, the laser beam emitted by the laser 41 needs to be reflected at an angle to the corresponding receiving end, so as to realize the distance measuring function. However, as shown in Figure 1 , the pin 11 described in the present application is in a semi-enclosed space formed by the injection molding structure in the terminal. This semi-enclosed structure makes it impossible for the laser beam to be effectively reflected to the receiving end, resulting in that the laser 41 cannot directly measure the size of the pin 11.

[0030] In order to solve this problem, the base 2 is provided with a detection assembly 6. The detection assembly 6 is arranged adjacent to the jig 3, and includes a detector 61 capable of abutting against the terminal in the jig 3, the detector 61 being connected with a detection driving mechanism 62 and moving relative to the terminal under the driving of the detection driving mechanism 62. As shown in Figure 3 The number of the detectors 61 is set according to the number of the pins 11, specifically, the number of the pins 11 + 1, one of which is configured as a reference pin 61a for abutting against the base 2 surface of the terminal, and the others are configured as detection pins 61b for abutting against the pins 11.

[0031] The reference pin 61a and the detection pin 61b both have a needle body 611 penetrating through the detection driving mechanism 62 and being connected with a mounting seat 623 through a buffer 612. When one end of any needle body 611 abuts against the reference surface 12 or the pin 11 under the driving of the detection driving mechanism 62, the corresponding buffer 612 is compressed, so that the remaining needle bodies 611 can continue to move towards the reference surface 12 or the pin 11.

[0032] When the reference surface 12 and the pin 11 on the terminal both abut against the corresponding needle body 611, the detection driving mechanism 62 stops acting, and the distance measuring unit 4 starts to measure the height of the end of the reference pin 61a away from the reference surface 12 and the end of the detection pin 61b away from the pin 11 respectively, and obtains the height difference between the end of any detection pin 61b away from the pin 11 and the end of the reference pin 61a away from the reference surface 12. If the obtained height difference is within a preset range, the size of the pin 11 of the terminal is normal, otherwise the manufacturing of the pin 11 is unqualified.

[0033] Specifically, the detection driving mechanism 62 includes a detection bracket 621 fixed with the base 2, a detection driver 622 being mounted on the detection bracket 621 in the vertical direction, and the mounting seat 623 being fixed on the execution end of the detection driver 622 in the horizontal direction, and the reference pin 61a and the detection pin 61b being perpendicularly mounted on the mounting seat 623. In this embodiment, the buffer 612 is set as a spring, which is sleeved on the outer wall of the needle body 611 and abuts against the end of the needle body 611 at one end and the mounting seat 623 at the other end.

[0034] When working:

[0035] The terminal is put into the mounting cavity 31 and is pressed by the pressing plate 51. The detection assembly 6 drives the detector 61 to act, so that the corresponding reference pin 61a and detection pin 61b abut against the reference surface 12 and the pin 11 in the terminal respectively. Then the distance measuring unit 4 measures the distance of the reference pin 61a and the detection pin 61b respectively, and judges whether the size of the pin 11 is qualified by calculating the height difference between the reference pin 61a and the detection pin 61b.

[0036] The above examples are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and to implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application, therefore, from any point of view, the examples should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
