Technical Field

[0001] This utility model relates to the field of audio and video circuit board processing technology, and in particular to a positioning structure for audio and video circuit board processing. Background Technology

[0002] Audio and video circuit boards (AV circuit boards) are core electronic components used to process, transmit, and convert audio and video signals. They typically integrate multiple functional modules and are fundamental to the normal operation of various audio and video devices. AV circuit boards are commonly used in electronic products such as televisions, audio systems, and cameras, and the market demand is substantial, thus requiring high production efficiency.

[0003] However, existing circuit board positioning methods are complex to operate, requiring manual clamping or unloading by workers during the production process. This consumes a lot of time on the positioning and adjustment of the circuit boards, resulting in extended production cycles and failing to meet the needs of large-scale production.

[0028] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Please see Figures 1 to 5 The present invention provides a positioning structure for processing audio and video circuit boards, comprising two guide rails 10 arranged opposite to each other, positioning components 20 respectively installed on the outside of each guide rail 10, and locking components 30 respectively installed on top of each positioning component 20.

[0032] The inner surface of the guide rail 10 is provided with guide grooves 11 along its length. Two guide grooves 11 fit together to allow the audio / video circuit board 40 to pass through. For example... Figure 1As shown, the audio and video circuit board 40 has positioning holes 41 at its four opposite corners. The positioning holes 41 are located outside the guide groove 11 and are used for the positioning component 20 to be inserted to achieve positioning.

[0033] A fiber optic sensor 12 is installed at one end of the guide rail 10. The fiber optic sensor 12 is used to detect whether the audio / video circuit board 40 is in place after passing through the guide rail 10. Specifically, as shown... Figure 2 As shown, the guide rail 10 has a through hole 13 corresponding to the inside of the guide groove 11. The fiber optic sensor 12 is inserted into the through hole 13, so that the fiber optic sensor 12 can detect the audio and video circuit board 40.

[0034] Furthermore, the top surface of the guide rail 10 is provided with an avoidance notch 14, which is located above the through hole 13 and is used to avoid the positioning component 20.

[0035] The positioning assembly 20 includes a column 21 installed on the outside of the guide rail 10, a rodless cylinder 22 installed on the inside of the column 21, a lifting plate 23 connected to the slider of the rodless cylinder 22, and a positioning pin 24 installed on one side of the bottom end of the lifting plate 23. The lifting plate 23 is located directly above the guide rail 10, and the positioning pin 24 is offset from the guide rail 10. The positioning pin 24 is used to correspondingly insert into the positioning hole 41. By utilizing the synergistic effect of the positioning pin 24 and the two guide rails 10, the audio-visual circuit board 40 is effectively restricted in three dimensions to achieve the positioning of the audio-visual circuit board 40.

[0036] In this embodiment, the rodless cylinder 22 is a magnetically coupled rodless cylinder, and the movement direction of the rodless cylinder 22 is perpendicular to the top surface of the guide rail 10.

[0037] In this embodiment, the positioning pin 24 is connected to one side of the bottom end of the lifting plate 23 via the adapter piece 25, wherein the adapter piece 25 is L-shaped and the bottom end of the adapter piece 25 corresponds to the clearance notch 14.

[0038] In this embodiment, as Figure 3 As shown, the positioning pin 24 has a three-section design, including a fixing section 241, a wedge-tightening section 242 that gradually narrows inward from one end of the fixing end 241 along its axial direction, and an inserting section 243 that extends from the end of the wedge-tightening section 242 away from the fixing section 241. The fixing section 241 is used to connect the adapter piece 25, and the wedge-tightening section 242 and the inserting section 243 are used to insert into the positioning hole 41.

[0039] Furthermore, both the fixing section 241 and the embedding section 243 are cylindrical, with the diameter of the fixing section 241 being larger than that of the embedding section 243. The wedge-tightening section 242 is frustum-shaped, with its diameter gradually decreasing from the fixing section 241 towards the embedding section 243. The wedge-tightening effect between the wedge-tightening section 242 and the positioning hole 41 effectively improves the positioning effect of the audio / video circuit board 40.

[0040] The locking assembly 30 includes a fixed base 31 mounted above the rodless cylinder 22, a locking hook 32 hinged to the fixed base 31, a swing arm 33 connected to the locking hook 32, and a push-pull cylinder 34 mounted on one side of the fixed base 31; the push-pull cylinder 34 is hinged to the swing arm 33. The swing arm 33 is fixed relative to the locking hook 32, and the push-pull cylinder 34 drives the locking hook 32 to oscillate around the fixed base 31.

[0041] Specifically, during locking, the positioning pin 24 is first driven to insert into the positioning hole 41. Then, the push-pull cylinder 34 drives the locking hook 32 to swing inward, with the bottom end of the locking hook 32 abutting against the top end of the lifting plate 23 to limit the height of the lifting plate 23 and ensure that the positioning pin 24 is always inserted into the positioning hole 41, thus achieving locking. Conversely, during unlocking, the push-pull cylinder 34 drives the locking hook 32 to swing outward, with the bottom end of the locking hook 32 moving away from the top end of the lifting plate 23 to create space. Then, the lifting plate 23 moves upward, and the positioning pin 24 disengages from the positioning hole 41, thus achieving unlocking.

[0042] The above-mentioned audio and video circuit board processing positioning structure is simple in structure and easy to use. By utilizing the synergistic effect of the positioning pin 24 and the two guide rails 10, and with the locking hook 32 abutting against the lifting plate 23, the audio and video circuit board 40 is effectively restricted in three dimensions to achieve the positioning of the audio and video circuit board 40.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and 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 those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
