DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] In order to solve the above technical problems, this embodiment provides a horn plate pin guide fixture, such as Figure 1 As shown, it includes a fixing seat 30, a horn plate 10 and a guide plate 20 which are sequentially installed on the fixing seat 30 from bottom to top. The horn plate 10 is provided with a plurality of mounting holes 11 for inserting pins, and a guide hole 21 corresponding to each mounting hole 11 is provided on the guide plate 20. The horn plate 10 is first fixed on the fixing seat 30, and then the guide plate 20 is placed parallel to the horn plate 10, and the PIN pin is placed on the guide hole 21 of the guide plate 20, and then the PIN pin is pressed down by external force, so that the PIN pin passes through the guide hole 21 and is inserted and fixed in the mounting hole 11 of the horn plate 10. During the pressing process of the PIN pin, the guide plate 20 guides the PIN pin, so as to ensure that the PIN pin will not bend or deviate from the correct direction during the pressing process to the horn plate 10, and ensure that the pin pin on the subsequent horn plate is accurately aligned with the test machine, so as to ensure the detection result of the circuit board.

[0019] Specifically, a mounting groove 31 is provided on the top surface of the fixing seat 30, and the horn plate 10 and the guide plate 20 are fixedly connected to the mounting groove 31. The mounting groove 31 of the fixing seat 30 effectively prevents the horn plate 10 and the guide plate 20 from moving in the horizontal direction. The horn plate 10 and the guide plate 20 are limited by the mounting groove 31 to ensure that the PIN pin will not be offset or bent during the process of installing the PIN pin to the mounting hole 11 of the horn plate 10 through the guide plate 20. For example, when installing some PIN pins of a longer length, the mounting groove 31 can provide the PIN pin with an air avoidance effect.

[0020] Specifically, the horn plate 10 and the guide plate 20 are provided with through holes for connection and fixation, and the fixing seat 30 is provided with a plurality of fixing holes 00. The horn plate 10 and the guide plate 20 are fixedly connected through the fixing holes 00 of the fixing seat 30, and the horn plate 10 and the guide plate 20 can be firmly connected to the fixing seat 30 through the locking member and the fixing hole 00. Exemplarily, the guide plate 20 and the horn plate 10 can be fixed to the fixing seat 30 by tightening the locking member in the fixing hole 00 at the same time. By providing a plurality of fixing holes 00 in the fixing seat 30, horn plates 10 and guide plates 20 of different specifications can be adapted, so that the fixed connection of different fixtures can be applied, thereby improving compatibility.

[0021] On the other hand, this embodiment also provides a pin insertion device, such as Figure 2 As shown, it includes the above-mentioned pin guide fixture, the mounting plate 50 for placing the fixing seat 30, and the pressing assembly 60 located above the mounting plate 50. The driving end of the pressing assembly 60 is connected to the pressing plate 40. The pressing assembly 60 is used to drive the pressing plate 40 to press down on the pin guide fixture along the first direction. The pressing plate 40 is driven by the pressing assembly 60 to move toward the pin guide fixture. The pressing plate can accurately press down the pin guide fixture along the first direction to ensure that the PIN pins on the guide plate 20 are evenly stressed and stably inserted into the mounting hole 11 of the horn plate 10. The guiding effect of the guide plate 20 prevents the PIN pins from bending. At the same time, the combination of the pin guide fixture and the pressing assembly 60 makes the entire PIN pin insertion process more automated, reduces manual intervention, and improves efficiency. The pressing assembly 60 can ensure that the pressing plate 40 presses down the PIN pin vertically, preventing the PIN pin from bending or deviating from the correct direction, thereby ensuring the accuracy and reliability of the PIN pin test. By installing the plate 50, the pin insertion device can process multiple pin guide fixtures in batches, further improving the PIN pin test efficiency.

[0022] Specifically, the pin insertion device also includes a mounting frame 70, which provides stable support for the entire pin insertion device. A first linear drive module 80 is arranged on the mounting frame 70. The pressing assembly 60 is connected to the driving end of the first linear drive module 80. The first linear drive module 80 drives the pressing assembly 60 to move along the second direction, so that the pressing assembly 60 can be accurately controlled by the first linear drive module 80 to be in the second direction, thereby expanding the range of motion of the pressing assembly 60.

[0023] Specifically, a slide rail 71 extending along the second direction is provided on the mounting frame 70, and the pressing assembly 60 is slidably connected to the slide rail 71. The slide rail 71 enables the pressing assembly 60 to slide smoothly in the second direction, and precise movement in the second direction is achieved through the drive of the first linear drive module 80.

[0024] Specifically, it also includes a second linear drive module 90 for driving the mounting frame 70 to move along the third direction. The first direction, the second direction and the third direction are perpendicular to each other. The mounting frame 70 is provided with a slide rail 71 extending along the second direction. The pressing assembly 60 is slidably connected via the slide rail 71 so that it can move in the second direction. The pin insertion device also includes a second linear drive module 90, which is used to drive the mounting frame 70 to move along the third direction. In this embodiment, Figure 2As shown, the first direction is the Z direction in the figure, the Y direction is the second direction, and the X direction is the third direction. The first direction, the second direction and the third direction are perpendicular to each other, providing the entire pin insertion device with the flexibility to move in different directions. Among them, the first linear drive module 80 and the second linear drive module 90 can be a linear displacement mechanism composed of a screw rod, a slide and a motor, which is a more existing structure and will not be described here.

[0025] Specifically, the mounting plate 50 is provided with a plurality of limit grooves 51 for limiting the movement of the fixing seat 30. The limit grooves 51 of the mounting plate 50 can limit the fixing seat 30, further ensuring that the fixing seat 30 maintains a relatively stable position during the process of the PIN needle being pressed into the horn plate 10. At the same time, by setting the limit grooves 51 on the mounting plate 50, multiple fixing seats 30 can be placed at one time to improve work efficiency.

[0026] The above-described implementation methods do not constitute a limitation on the protection scope of the technical solution. Any modification, equivalent replacement and improvement made within the spirit and principle of the above-described implementation methods shall be included in the protection scope of the technical solution.
