DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present application are only for the convenience of clear description, and are not used to limit the scope of the present application. The change or adjustment of the relative relationship is also considered as the scope of the present application without substantial change of the technical content.

[0022] Referring to Figures 1-4 A precise positioning DOME sheet pasting and pressing integrated device for circuit board, comprising a base 1 and a pressing machine 5 (wherein the pressing machine 5 has been disclosed in the patent document with publication number CN220075706U), a support 11 with an I-shaped cross section is fixedly connected to the base 1, and a rectangular block 9 is fixedly connected to the base 1, a bearing frame 3 is rotatably installed on the support 11, a placing groove is formed in the bearing frame 3, an inclined groove 2 is formed in the base 1, the upper surface of the rectangular block 9 and the bottom surface of the support 11 are attached, a concave rod 17 is connected to the rectangular block 9 through a torsion spring 16, two symmetrical rotating blocks 15 are fixedly connected to the concave rod 17, a hydraulic cylinder is fixedly installed on the base 1, a bent rod 13 is fixedly connected to the driving end of the hydraulic cylinder, two first extrusion rods 18 and two second extrusion rods 8 are fixedly connected to the bent rod 13, and two sliding assemblies are installed on the support 11.

[0023] The two side surfaces of the bearing frame 3 are fixedly installed with fixed blocks 12, two symmetrical grooves 14 are formed in the bent rod 13, when the inner walls of the two grooves 14 in the bent rod 13 are attached to the upper and lower surfaces of the two fixed blocks 12 respectively, the fixed blocks 12 can be prevented from moving up and down, thereby avoiding the relative rotation between the bearing frame 3 and the support 11, each sliding assembly comprises a sliding rod 7 slidingly installed on the support 11, a limiting block 6 is fixedly connected to one end of the sliding rod 7, a return spring is sleeved on each sliding rod 7, one end of the return spring is fixedly connected to the support 11, the other end of the return spring is fixedly connected to the sliding rod 7, and an inclined surface 4 is arranged on each sliding rod 7.

[0024] Each second extrusion rod 8 is in contact with the corresponding inclined surface 4. During the movement of each second extrusion rod 8, it will gradually move against the corresponding inclined surface 4. At the same time, the slide rod 7 slides relative to the bracket 11, the return spring deforms, and the distance between the two slide rods 7 decreases. In the initial state, both limit blocks 6 are located outside the placement groove. After each limit block 6 moves together with the slide rod 7, one end of the limit block 6 will move into the inside of the placement groove, and the surface of the limit block 6 will be in contact with one side surface of the DOME sheet workpiece, which can effectively prevent the DOME sheet workpiece from detaching from the placement groove. At this time, the DOME sheet workpiece is located directly below the press 5, which can achieve precise positioning of the DOME sheet workpiece.

[0025] A collection frame 10 is provided on the base 1 below the inclined groove 2. A handle is fixedly installed on one side surface of the collection frame 10. During the process of the carrier frame 3 changing from a horizontal state to an inclined state, the carrier frame 3 will not collide with the limit block 6. The DOME sheet workpiece processed in the groove will slide into the inclined groove 2 and eventually automatically slide into the collection frame 10 for collection.

[0026] In this invention, initially, the lower surface of the support frame 3 is in contact with the upper surface of the rectangular block 9. At this time, the support frame 3 is parallel to the upper surface of the base 1, i.e., the support frame 3 is in a horizontal state. Then, the DOME sheet workpiece is placed in the placement groove of the support frame 3, and the surface of the DOME sheet workpiece is in contact with the inner walls of each side of the placement groove. At this time, none of the second extrusion rods 8 are in contact with the sliding rod 7. Then, the hydraulic cylinder drives the bending rod 13 to move backward (as shown in the attached figure). Figure 1 As shown), under the transmission action of the bending rod 13, each of the first extrusion rods 18 and the second extrusion rod 8 will move together. During the movement of each second extrusion rod 8, it will gradually move against the corresponding inclined surface 4. At the same time, the slide rod 7 will slide relative to the bracket 11, the return spring will deform, and the distance between the two slide rods 7 will decrease. In the initial state, both limit blocks 6 are located outside the placement groove. After each limit block 6 moves together with the slide rod 7, one end of the limit block 6 will move into the interior of the placement groove, and the surface of the limit block 6 will be in contact with one side surface of the DOME sheet workpiece. At this time, the inner walls of the two slots 14 on the bending rod 13 are in contact with the upper and lower surfaces of the two fixing blocks 12 respectively, and the DOME sheet workpiece is located directly below the press machine 5, which can achieve precise positioning.

[0027] Finally, the pressing machine 5 works, and the DOME sheet workpiece can be pressed, after the pressing treatment, the hydraulic cylinder drives the bending rod 13 to move forward, the slot 14 is separated from the fixed block 12, and each second extrusion rod 8 is separated from the slide rod 7, under the elastic force of the reset spring, the limiting block 6 is repositioned on the outside of the placing slot, in the process of the bending rod 13 continuing to move forward, each first extrusion rod 18 moves against the surface of the concave rod 17, the concave rod 17 rotates relative to the rectangular block 9, the torsion spring 16 is fixedly connected with the concave rod 17 and the rectangular block 9, and the torsion spring 16 is deformed, in the process that the two rotating blocks 15 rotate upwards, the two rotating blocks 15 move against the lower surface of the bearing frame 3, the bearing frame 3 rotates upwards, and the bearing frame 3 changes from a horizontal state to an inclined state, in the process, the bearing frame 3 does not collide with the limiting block 6, the inner wall of the placing slot is smooth, the processed DOME sheet workpiece in the placing slot slides into the chute 2 and finally automatically slides into the collecting frame 10, and the DOME sheet does not need to be manually taken out, the operation is relatively quick and convenient, the pressing efficiency of the DOME sheet is relatively high, and the processing of the DOME sheet is facilitated.

[0028] In the present application, unless otherwise expressly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense.

[0029] The above is only a preferred embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
