Description

Technical Field

[0001] This utility model relates to the field of circuit board manufacturing technology, and in particular to a fixture for circuit board manufacturing. Background Technology

[0002] With the booming development of the electronics industry, the demand for printed circuit boards (PCBs), as a key component of various electronic devices, is increasing daily. Stable clamping of PCBs is a crucial step in ensuring production quality and efficiency during the manufacturing process.

[0003] Currently, existing fixtures for circuit board production have many problems. On the one hand, the adaptability of the fixtures is poor. Circuit boards of different specifications and sizes are common in production, but the clamping range of traditional fixtures is fixed and it is difficult to adjust them flexibly according to the actual size of the circuit board. This results in the need to frequently change fixtures when producing circuit boards of different specifications, which increases production costs and operational complexity.

[0004] On the other hand, the clamping stability is insufficient. During the production process, the circuit board may be affected by external forces or equipment vibration. Due to unreasonable structural design, traditional clamps cannot provide sufficient and stable clamping force, which can easily cause the circuit board to shift or loosen, thereby affecting the processing accuracy of the circuit board and even leading to product scrap. Utility Model Content

[0012] As an improvement, the beneficial effects of this utility model are as follows:

[0013] This utility model discloses a clamp for circuit board production. The adjusting rod in the adjusting assembly features a reverse thread design. Rotating the adjusting knob causes the lead screw and nut pair to move the clamping assembly. This, combined with the guide assembly, achieves synchronized movement of the clamping assembly, making it adaptable to circuit boards of different sizes.

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Identical components are indicated by the same reference numerals.

[0025] This embodiment provides a fixture for circuit board production, including a base plate 1, an adjustment component 2 on the upper side wall of the base plate 1, a guide component 3 on the side of the base plate 1 away from the adjustment component 2, a clamping component 4 on the adjustment component 2, and a clamping component 5 on the guide component 3. The clamping component 4 and the clamping component 5 have the same structure.

[0026] In this embodiment, the specific structure of the adjusting component 2 is as follows: Adjusting horizontal plate one 201 and adjusting horizontal plate two 202 are symmetrically welded to the side wall of the base plate 1. An adjusting rod 203 is rotatably mounted on the inner wall of adjusting horizontal plate one 201 via a bearing. One end of the adjusting rod 203, away from the inner wall of adjusting horizontal plate one 201, passes through adjusting horizontal plate two 202 and is welded to an adjusting knob 204. Adjusting thread one 205 and adjusting thread two 206 are provided on the adjusting rod 203, with opposite thread directions. A lead screw nut pair 207 is threaded onto adjusting thread one 205 and adjusting thread two 206 respectively. Adjusting connecting rod one 208 is welded below the lead screw nut pair 207, and adjusting connecting rod two 209 is welded above it. When the adjusting knob 204 is rotated, the adjusting rod 203 rotates. Because adjusting thread one 205 and adjusting thread two 206 have opposite thread directions, the two lead screw nut pairs 207 will move closer to or further away from each other.

[0027] In this embodiment, the guide assembly 3 has the following structure: a guide horizontal plate 301 and a guide horizontal plate 302 are welded to the side wall of the base plate 1, and a guide shaft 303 is fixedly installed between them. A guide shaft sleeve 304 is fitted onto the guide shaft 303. A guide connecting rod 305 is welded to the bottom of the guide shaft sleeve 304, and a guide connecting rod 306 is welded to the top. The guide connecting rod 305 and the adjusting connecting rod 208 are connected by a fixed rod 307. When the adjusting assembly 2 is working, the guide shaft sleeve 304 moves along the guide shaft 303 driven by the fixed rod 307, thus providing guidance and ensuring that the clamping assembly 2 5 and the clamping assembly 4 move synchronously.

[0028] In this embodiment, the specific structure of the clamping assembly 4 is as follows: a clamping frame 401 is welded onto the adjusting connecting rod 209. A clamping threaded rod 402 is threaded onto the clamping frame 401. A clamping knob 403 is welded to one end of the clamping threaded rod 402, and the other end is rotatably connected to the clamping plate 404 via a bearing. A clamping limiting rod 405 is welded to the inner wall of the clamping plate 404. The end of the clamping limiting rod 405 away from the clamping plate 404 passes through the clamping frame 401 and is welded to the clamping limiting plate 406. Rotating the clamping knob 403 causes the clamping threaded rod 402 to rotate, which in turn moves the clamping plate 404, thereby clamping or releasing the circuit board. The clamping limiting rod 405 and the clamping limiting plate 406 serve as limiting devices to prevent the clamping plate 404 from rotating.

[0029] In actual use, the circuit board is placed between clamping component 4 and clamping component 5. The adjusting knob 204 is rotated to bring clamping component 4 and clamping component 5 closer to each other until they reach a suitable position. Then, the clamping knobs 403 on clamping component 4 and clamping component 5 are rotated respectively to clamp and fix the circuit board for subsequent circuit board production operations.

[0030] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
