[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a positioning fixture for PCB circuit board processing.

[0025] Example 1:

[0026] Combination Figure 1-4 As shown, the present invention provides a positioning fixture for PCB circuit board processing, comprising: a base 100 and a positioning component 200; the base 100 includes a fixture table 101 fixedly installed at its upper end; the positioning component 200 includes a positioning opening 201 at the upper end of the fixture table 101, multiple sets of positioning blocks 202 fixedly installed at the outer end of the positioning opening 201, a circuit board component 203 movably installed inside the positioning opening 201, a clamping frame 204 movably installed at the upper end of the circuit board component 203, a left connecting plate 205 and a right connecting plate 206 fixedly installed at both ends of the clamping frame 204 respectively, a binding hole 207 opened on one side inside the fixture table 101, a binding rod 208 movably installed inside the binding hole 207, and a spring 209 movably installed at the outer end of the binding rod 208. A fixing post 210 is fixedly installed at the bottom of the right connecting plate 206. A mounting hole 211 is opened on one side of the fixture table 101, and the fixing post 210 matches the mounting hole 211. The fixing post 210 and the fixture table 101 are respectively provided with insertion holes 212 and threaded holes 213. Screws 214 are movably installed in the insertion holes 212 and threaded holes 213. Positioning holes 215 are also opened in the positioning blocks 202. Positioning posts 216 are arranged and fixedly installed at the bottom of the clamping frame 204, and the positioning posts 216 match the positioning holes 215. A placement opening 217 is opened in the middle of the fixture table 101. A lifting handle 218 is fixedly installed at the top of the left connecting plate 205. The top of the restraint rod 208 is fixed to the bottom of the left connecting plate 205.

[0027] Specifically, a PCB (Printed Circuit Board) is the carrier for the electrical connection of electronic components. A PCB positioning fixture is a specialized tool used to fix and position the PCB, ensuring high precision and stability during processing. The positioning port 201 located in the center of the fixture table 101, and the positioning blocks 202 located at the outer ends of the four corners of the positioning port 201, allow for the positioning and placement of the PCB component 203 during processing. Simultaneously, the clamping frame 204 mounted on one side of the fixture table 101 can also be rotated for positioning. Installed on the upper part of the circuit board 203, the frame structure evenly positions and clamps the four sides of the circuit board 203 to ensure the stability of the circuit board 203 during processing. After the circuit board 203 is processed, the screw 214 at one end of the clamping frame 204 is loosened, and the clamping frame 204 is lifted and rotated to easily remove it, facilitating the removal of the processed circuit board 203 and the installation of the unprocessed circuit board 203. The positioning block 202 at the outer end of the positioning port 201, i.e. The binding rod 208, installed in the binding hole 207 at the bottom of the left connecting plate 205, can be used for mounting and positioning of circuit board 203, and can also be used to block circuit board 203 to ensure processing stability. The binding rod 208 can be used to clamp the clamping frame 204 by the spring 209 at its outer end. It can also be lifted and rotated to open the clamping frame 204. The fixing post 210 at the bottom of the right connecting plate 206 is mainly positioned and installed in the mounting hole 211, and can be locked in the insertion hole 212 by the screw 214 in the threaded hole 213 to complete the fixing. The fixing of the fixed column 210 and the clamping frame 204 ensures the stability of the circuit board 203 under the clamping frame 204 during processing. The positioning hole 215 in the positioning block 202 and the positioning column 216 installed at the bottom of the clamping frame 204 are mainly used to position the clamping position of the clamping frame 204. The placement opening 217 on the fixture table 101 is mainly for the installation and removal of the circuit board 203. The lifting handle 218 fixedly installed at the upper end of the left connecting plate 205 is mainly for the overall lifting and adjustment of the clamping frame 204.

[0028] Working principle and usage process of this utility model:

[0029] When positioning and installing circuit board 203, first position and install circuit board 203 into the positioning port 201 at the upper end of the fixture table 101, and bind it to the inner end of the positioning block 202 at the outer end of the positioning port 201. After the circuit board 203 is positioned and installed in the positioning port 201, lift and rotate the entire clamping frame 204 by lifting handle 218, so that the clamping frame 204 rotates to the upper part of the circuit board 203. At this time, slowly move the clamping frame 204 down, and position and install the fixing post 210 at the bottom of the right connecting plate 206 into the mounting hole 2. Within 11, as the clamping frame 204 moves downward, the positioning post 216 at the bottom of the clamping frame 204 is matched and installed into the positioning hole 215 to position and clamp the clamping frame 204 to the upper end of the circuit board 203. Finally, by gently pressing the clamping frame 204, the screw 214 in the threaded hole 213 is rotated to lock the inner end of the screw 214 into the insertion hole 212 in the fixing post 210 to lock and fix the clamping frame 204, thereby ensuring the stability of the circuit board 203 after positioning and installation on the fixture table 101 during processing.

[0030] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
