[0026] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0027] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 7 , is a PCB board batch fixing fixture according to an embodiment of the present invention, comprising a carrier board 10 and a plurality of clamping components 20 evenly spaced and installed inside the carrier board 10.

[0030] The carrier board 10 is provided with a plurality of evenly spaced positioning cavities 11 for positioning and accommodating PCBs. These cavities 11 can be used to secure multiple PCBs in batches, significantly improving positioning efficiency and accuracy. Through-holes 12 are provided in the center of the carrier board 10, corresponding to each of the positioning cavities 11. These holes 12 penetrate the carrier board 10 to expose the bottom surface of the PCBs, facilitating processing of the bottom surface of the PCBs.

[0031] A sliding cavity 13 is provided on one side of the carrier plate 10 corresponding to the positioning cavity 11. The sliding cavity 13 communicates with the positioning cavity 11 and is used for sliding connection with the clamping assembly 20. An operating slot 14 is provided in the middle of the carrier plate 10 corresponding to the sliding cavity 13. The operating slot 14 extends through the carrier plate 10 and aligns with the length of the sliding cavity 13, but is shorter than the length of the sliding cavity 13.

[0032] In this embodiment, the positioning cavity 11 is rectangular, and the sliding cavity 13 is arranged along the diagonal direction of the positioning cavity 11. Simply put, the sliding cavity 13 points from one corner of the positioning cavity 11 to the other diagonal corner thereof, effectively strengthening the clamping of the PCB board.

[0033] Furthermore, in this embodiment, Figure 3 and Figure 5 As shown, the carrier plate 10 is further provided with inwardly recessed limiting grooves 15 on the inner walls on opposite sides of the sliding cavity 13 , so as to better limit the clamping assembly 20 inside the sliding cavity 13 .

[0034] The clamping assembly 20 includes a positioning slider 21 that slides within the sliding cavity 13 and a spring 22 connected to the rear end of the positioning slider 21. The end of the spring 22, distal from the positioning slider 21, abuts the inner wall of the sliding cavity 13. The spring 22 is used to drive the positioning slider 21 toward the positioning cavity 11, causing the head of the positioning slider 21 to abut against the PCB, achieving a clamping effect. Specifically, the head of the positioning slider 21 is provided with a generally V-shaped positioning notch 210, which is designed to align with the corners of the PCB.

[0035] In this embodiment, if Figure 6 and Figure 7 As shown, an operating hole 23 is defined in the middle of the positioning slider 21 along its thickness. The operating hole 23 extends through the positioning slider 21 and corresponds to the operating slot 14. In actual operation, processing equipment can be inserted into the operating hole 23 through the operating slot 14, controlling the positioning slider 21 to compress the spring 22, releasing the positioning cavity 11, and facilitating the removal and placement of PCBs.

[0036] Furthermore, in this embodiment, the bottom surface of the positioning slider 21 is also connected to a limiting plate 24, and the opposite sides of the limiting plate 24 are respectively embedded in the limiting grooves 15, which can effectively limit the positioning slider 21 inside the sliding cavity 13, greatly improving the stability of the movement of the positioning slider 21, and thereby improving the positioning efficiency and positioning accuracy.

[0037] The above-mentioned PCB board batch fixing fixture has a simple structure and is easy to use. The carrier plate 10 is provided with multiple positioning cavities 11. The positioning slider 21 is driven by a spring 22 to automatically clamp the PCB board. Multiple PCB boards can be fixed in batches, greatly improving positioning efficiency and positioning accuracy.

[0038] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
