[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Referring to Figures (1-3), a bending resistance testing fixture for circuit board processing includes a base 1. The base 1 has an opening, and multiple mounting plates 11 are slidably disposed on the opening. The mounting plates 11 have mounting grooves 16, and support members 2 are slidably disposed on the mounting grooves 16. An air rod 5 is disposed above the base 1. An extrusion member 3 is fixedly connected to the telescopic end of the air rod 5. A sliding groove 31 is provided at the bottom of the extrusion member 3. A slider 33 is slidably disposed in the sliding groove 31. A spring 32 is disposed in the sliding groove 31. One end of the slider 33 extends out of the sliding groove 31 and is connected to an extrusion head 4.

[0017] The mounting plate 11 is provided with slide rods 14 at both ends. The outer surface of the slide rod 14 is provided with threads, and one end passes through the base 1 and is screwed with a first nut 15. A limit groove 12 is formed in the base 1, and a limit block 13 is fixedly provided on the slide rod 14. The limit block 13 and the slide rod 14 are slidably disposed in the limit groove 12.

[0018] The support member 2 has a bottom post 21 at its bottom, and the outer surface of the bottom post 21 is threaded and screwed with a second nut 22. The support frame 2 has a mounting member 23 at its top, and the mounting member 23 has a screw hole at its top for screw installation. The support frame 2 has a groove at its top, and the inner wall of the groove is threaded. The mounting member 23 has a stud at its bottom, which is screwed into the groove at the top of the support member 2.

[0019] One end of the spring 32 is connected to the slider 33, and the other end is connected to the pressure sensor set in the groove 31. The bottom of the slider 33 is provided with a groove, and the top of the extrusion head 4 is provided with a protrusion. Holes for bolts to pass through are provided on the bottom groove sidewall of the slider 33 and the top protrusion of the extrusion head 4.

[0020] In use, the position of the movable mounting plate 11 on the base 1 and the position of the support frame 2 on the mounting groove 16 are adjusted. The positions of the mounting plate 11 and the support frame 2 are fixed by tightening the first nut 15 and the second nut, respectively. The circuit board is placed on the base 1, so that the position of the mounting hole on the circuit board is aligned with the screw hole on the mounting part 23. The circuit board is fixed on the base by tightening the screw. The extrusion head 4 is installed at the bottom of the slider 33. The extrusion part 3 is driven downward by the air rod, so that the extrusion head contacts the circuit board and bends it. When the extrusion head 23 extrudes the circuit board, the spring is compressed. The pressure on the circuit board is the sum of the weight of the slider and the extrusion head plus the spring force detected by the pressure sensor connected to the spring. Thus, the extrusion force on the circuit board when it bends can be detected. By changing different extrusion heads, the contact area between the extrusion head and the circuit board can be changed.

[0021] The orientations or positional relationships shown in the accompanying drawings are for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
