DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-8 The utility model provides a technical solution: a clamping device for circuit board production, including a base plate 1, a fixed column 2, a fixed block 3, an adjusting column 4, a fixing mechanism 5, a fixing sleeve 6, a fixing ring 7, a fixing frame 8, a fixing strip 9, a connecting plate 10, a connecting bolt 11, a fixing clamp 12, an adjusting block 13, a supporting block 14, a fixing rod 15, a spring 16, a fixing bracket 17 and a protrusion 18.

[0034] When using the clamping device for circuit board production, Figure 1 , Figure 2 and Figure 3 As shown, the upper end of the bottom plate 1 is fixedly connected with a fixing column 2, and the upper end of the fixing column 2 is fixedly connected with a fixing block 3, the adjustment column 4 is inserted in the middle of the fixing block 3, and the adjustment column 4 is fixedly connected with the fixing strip 9. Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, first, according to the size of the processed circuit board, by pressing the fixing bracket 17 downward, the fixing bracket 17 slides with the fixing rod 15, and the fixing bracket 17 squeezes the spring 16, so that the spring 16 is elastically deformed. At this time, the lower end of the fixing bracket 17 is separated from the protrusion 18, thereby releasing the limit between the adjustment block 13 and the fixed strip 9, and the adjustment block 13 and the support block 14 are connected to the card slot between the fixed strip 9, by pulling the adjustment block 13, the adjustment block 13 slides with the fixed strip 9, and the adjustment block 13 drives the connecting plate 10 to move, so as to facilitate the adjustment of the spacing between the connecting plates 10 and the connecting plates 10 at the front and rear ends, so as to facilitate the fixing of circuit boards of different sizes;

[0035] After the adjustment is completed, the fixing bracket 17 is directly released. At this time, the spring 16 restores its elastic deformation, driving the fixing bracket 17 to slide with the fixing rod 15. At this time, the lower end of the fixing bracket 17 is fixed between the protrusion 18 at the corresponding position, so as to facilitate the fixing of the fixing strip 9 and the adjusting block 13. Then, the processed circuit board is placed between the fixing clamping blocks 12 at the upper and lower ends and the fixing clamping blocks 12. Then, the connecting bolts 11 connected to the upper and lower ends of the connecting plate 10 are rotated by rotating the threaded connection bolts 11. The connecting bolts 11 and the fixing clamping blocks 12 are rotated, driving the fixing clamping blocks 12 to extend and retract in the middle of the connecting plate 10, so that the fixing clamping blocks 12 can stably clamp the circuit board, and then the circuit board is processed;

[0036] In addition, combined Figure 3 and Figure 4 As shown, the fixing mechanism 5 includes a fixing sleeve 6 for limiting, a fixing ring 7 sleeved on the outer surface of the upper end of the fixing column 2 and a fixing frame 8 for fixing. By rotating the fixing sleeve 6 threadedly connected to the upper end of the fixing column 2, the fixing sleeve 6 moves downward to release the limiting position of the fixing ring 7. At this time, the fixing ring 7 and the fixing frame 8 move downward under the action of gravity, and the bottom of the fixing frame 8 is disengaged from the fixing groove on the side of the adjusting column 4, thereby releasing the limiting position between the adjusting column 4 and the fixing block 3. Then the adjusting column 4 is rotated, and the adjusting column 4 and the fixing block 3 are rotated. The adjusting column 4 drives the circuit board to be flipped and adjusted through the fixing strip 9, thereby facilitating the flipping processing of the other side of the circuit board. After the flipping is completed, the fixing sleeve 6 is rotated in the opposite direction, and the fixing sleeve 6 and the fixing ring 7 are fitted together, so that the fixing ring 7 drives the fixing frame 8 to move upward and engage in the fixing groove at the corresponding position on the side of the adjusting column 4, thereby facilitating the limiting position between the adjusting column 4 and the fixing block 3.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
