[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The following is combined with Figure 1-4 The embodiments of the present application are described in further detail.

[0028] Combined with Figure 1-Figure 4 , an embodiment provided by the present application: a press-fit device for circuit board signal testing, comprising:

[0029] Base 1, which can ensure the stability of the upper structure during operation;

[0030] A guide rod 2 is vertically welded around the top of the base 1, and the guide rod 2 plays an effective role in stabilizing the structure on the rod when it is displaced; a top plate 3 is horizontally welded on the top of the guide rod 2, and the top plate 3 can effectively fix the structure above; and a vertical hole is opened in the center of the top plate 3.

[0031] The top vertical bolts of the top plate 3 are connected with a cylinder 4, which can conveniently drive the structure on the output end to perform vertical displacement; and the bottom output end of the cylinder 4 passes through the vertical hole of the top plate 3 and is located below the top plate 3, and the output end bolts of the cylinder 4 are connected with a fixing plate 5, which serves to connect the structures to each other; and the surrounding areas of the fixing plate 5 can slide vertically on the No. 1 guide rod 2, which ensures stability during vertical displacement.

[0032] The bottom of the fixed plate 5 is bolted to an upper template 6, which is convenient for providing effective extrusion during vertical displacement; and an elastic buffer plate is bonded to the bottom of the upper template 6, which can provide effective buffering during extrusion.

[0033] Adjustment mechanism 7, the adjustment mechanism 7 includes: a frame 701, the frame 701 serves to limit the inner structure; the bottom of the frame 701 is welded to the upper center of the base 1, which ensures the stability of the connection between the structures; and rectangular holes are provided at the lower sides of the frame 701 to facilitate the rotation of the internal structure; circular holes are provided at the upper sides of the frame 701 to facilitate the horizontal displacement of the internal structure; a No. 2 guide rod 702, the No. 2 guide rod 702 is slidably connected to the circular holes on both sides of the frame 701, and serves to effectively displace the structure on one side when the structure is displaced synchronously; and the diameter of the No. 2 guide rod 702 is smaller than the diameter of the circular holes on both sides of the frame 701 , a limit plate 703, one side of the limit plate 703 is welded to one end of the second guide rod 702, which is convenient for the subsequent displacement and plays an effective limit fixation on the circuit board; a fixed block 704, one end of the fixed block 704 is welded to the two ends of one side of the frame 701, which is convenient for the internal structure to rotate stably; and a bearing is welded inside the fixed block 704, and the two ends of the two-way screw rod 705 are fixed with the bearings inside the fixed block 704, which is convenient for driving the structure on the rod to move during rotation; and the limit plate 703 and the two ends of the two-way screw rod 705 are threadedly connected, and the central part of the two-way screw rod 705 is fixed with a round handle, which is convenient for subsequent manual rotation.

[0034] The frame 701 is vertically slidably connected to a lower template 8, and a plurality of probes are inserted into the upper holes of the lower template 8, so that the lower template 8 is convenient for placing the upper circuit board.

[0035] A connecting shaft 9 is vertically welded inside the rectangular holes on both sides of the frame 701, and the connecting shaft 9 facilitates the horizontal rotation of the structure on the shaft; the connecting shaft 9 is rotatably connected to a limit block 10, and the limit block 10 can fix the structure on the lower side when rotating 90°.

[0036] The implementation principle of a press-fit device for circuit board signal testing in the present application is as follows:

[0037] First, slide the lower template 8 vertically into the interior of the frame 701, and then hold the limit block 10 and rotate it on the connecting shaft 9. At this time, when the limit block 10 rotates, one side will limit the lower template 8 to prevent the lower template 8 from vertical displacement, and then place the circuit board horizontally on the lower template 8.

[0038] Secondly, by rotating the bidirectional screw rod 705, the bidirectional screw rod 705 drives the limit plate 703 on the rod to rotate and displace. At this time, the limit plate 703 is more stable during displacement through the second guide rod 702. When the limit plate 703 is displaced, it will limit and fix the two sides of the circuit board to prevent the circuit board from shaking.

[0039] Finally, start the cylinder 4, which drives the fixed plate 5 on the bottom output end to move vertically. When the fixed plate 5 moves vertically, it will simultaneously drive the upper template 6 at the bottom to move. The upper template 6 will vertically squeeze the circuit board to contact the lower template 8, so as to carry out subsequent testing work.

[0040] In order to achieve accurate limiting and fixing during the placement of the circuit board, this embodiment introduces a press-fitting device for circuit board signal testing, which includes key components such as an adjustment mechanism, a load-bearing frame, a pair of auxiliary guide rods, a limiting baffle, a fixing base, and a bidirectional threaded rod. During the placement of the circuit board, by cleverly utilizing the synergy between these components, efficient and accurate limiting constraints can be performed on both sides of the circuit board, thereby effectively preventing the possible slight deviation of the circuit board in subsequent operation steps, and ensuring the absolute stability of the circuit board positioning and the accuracy of the test results.

[0041] In addition, we have specially designed a sophisticated structure including a connecting shaft and a limit unit, which is designed to limit the lower template in all directions and position it in the vertical direction. When rotating, this structure can quickly respond and lock the position of the lower template, thereby significantly improving the structural rigidity and position stability of the lower template when it carries the circuit board above it, effectively ensuring that the circuit board is not affected by vibration or tilt during stacking or assembly, and maintaining the high precision requirements of the entire process.

[0042] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
