[0031] Example 2, reference Figure 2~Figure 6, which is the second embodiment of the present invention, is different from the first embodiment in that the side plate 101 includes a lifting groove 101a and a rack 101b, the rack 101b is arranged on the side of the lifting groove 101a, and the lifting groove 101a is arranged in the middle of the side plate 101.

[0032] Furthermore, the lifting member 102 includes a lifting rod 102a, the lifting rod 102a includes a lifting ring 102a-1, and the lifting rod 102a is slidably matched with the lifting rod 102a.

[0033] Preferably, the slide 103 is parallel to the conveying direction of the material to be processed, and the slide 103 includes a limiting path 103a and a placing path 103b. The limiting paths 103a are symmetrically arranged on both sides of the slide 103, and the placing path 103b is arranged in the middle of the slide 103. The limiting path 103a includes a limiting hole 103a-1, and the limiting hole 103a-1 is arranged at the inner end of the slide 103. The placing path 103b is symmetrically arranged with slide grooves 103b-1 on both sides.

[0034] Preferably, both ends of the rotating rod 104 are slidably matched with the side plate 101, and the rotating rod 104 includes a translation screw 104a and a rotation gear 104b. The translation screw 104a is symmetrically arranged on both sides of the rotating rod 104, and the rotation gear 104b is symmetrically arranged on both ends of the rotating rod 104, and the rotation gear 104b is meshed with the rack 101b.

[0035] Furthermore, the rotating rod 104 also includes a limit rod 104c and a crimping plate 104d, the limit rod 104c is arranged between the translation screw 104a and the rotating gear 104b, the limit rod 104c is slidingly matched with the lifting ring 102a-1, the crimping plate 104d is threadedly matched with the translation screw 104a, the limit rod 104c includes a blocking ring 104c-1 and a blocking ring 2 104c-2, the blocking ring 104c-1 and the blocking ring 2 104c-2 are respectively arranged on both sides of the limit rod 104c, the crimping plate 104d includes a synchronization ring 104d-1, a crimping piece 104d-2 and a connecting block 104d-3, a vertical lever 104d-21 is arranged at the end of the crimping piece 104d-2, and an extension rod 104d-31 is arranged on the side of the connecting block 104d-3.

[0036] On the basis of the previous embodiment, the lifting groove 101a and the rack 101b respectively provide activity space for the operation of the rotating rod 104, and the rack 101b on the side of the lifting groove 101a is meshed with the rotating gear 104b at the end of the rotating rod 104. When the limiting rod 104c is pushed up by the lifting ring 102a-1, due to the existence of the meshing, the rotating rod 104 will generate a rotational torque, thereby driving the synchronous ring 104d-1 in the crimping plate 104d to move, and the vertical lever 104d-21 is slidably matched with the connecting block 104d-3, and the connecting block 104d-3 plays a limiting role inside the limiting path 103a, and the extension rod 104d-31 penetrates into the limiting hole 103a-1, so the connecting block 104d-3 is also limited in the vertical space direction.

[0037] Example 3, reference Figure 1 to Figure 7 , which is the third embodiment of the present invention, based on the previous two embodiments: it also includes a mounting method for a PCB mounting device.

[0038] A PCB mounting device also includes a clamping assembly 105 including a single-mouth slot 105a and a rotating ring 105b, the single-mouth slot 105a includes an upper half slot 105a-1 and a lower half slot 105a-2, the lower half slot 105a-2 includes a hollow slot 105a-21 and a fixing ring 105a-22, the hollow slot 105a-21 is arranged in the middle of the lower half slot 105a-2, the fixing ring 105a-22 is arranged on the side of the lower half slot 105a-2, and the rotating ring 105b is arranged on the upper part of the single-mouth slot 105a.

[0039] Furthermore, the clamping assembly 105 also includes a scissors-type member 105c, which includes an active arm 105c-1, a driven arm 105c-2 and a hinge 105c-3. The active arm 105c-1 includes a translation rod 105c-11 and a pulling rod 105c-12, and the translation rod 105c-11 and the pulling rod 105c-12 are arranged in a corresponding manner. The driven arm 105c-2 includes a rotating head 105c-21 and a sliding head 105c-22, and the rotating head 105c-21 and the sliding head 105c-22 are arranged in a corresponding manner. The active arm 105c-1 and the driven arm 105c-2 are hingedly connected via the hinge 105c-3.

[0040] Specifically, a mounting method of a PCB mounting device includes placing a flexible PCB into the lower half groove 105a-2; starting the lifting member 102; the lower half groove 105a-2 holds up the PCB and the scissor member 105c of the clamping assembly 105 fixes the connecting structure in the middle of the flexible PCB; the translation screw 104a drives the synchronization ring 104d-1 to move toward the middle while squeezing the PCB circuit board that droops due to gravity; the crimping member 104d-2 bends and squeezes the PCB, so that the PCB is bent and fixed, and finally the crimping mounting is completed.

[0041] In combination with the previous two embodiments, the lifting groove 101a and the rack 101b respectively provide movement space for the operation of the rotating rod 104, and the rack 101b on the side of the lifting groove 101a is meshed with the rotating gear 104b at the end of the rotating rod 104. When the limiting rod 104c is pushed up by the lifting ring 102a-1, due to the existence of the meshing, the rotating rod 104 will generate a rotational torque, thereby driving the synchronous ring 104d-1 in the crimping plate 104d to move, and the vertical lever 104d-21 is slidably matched with the connecting block 104d-3, and the connecting block 104d-3 plays a limiting role inside the limiting path 103a. The extension rod 104d-31 penetrates into the limiting hole 103a-1, so the connecting block 104d-3 is also limited in the vertical space direction.

[0042] In this embodiment, the lower half groove 105a-2 of the clamping assembly 105 is used as a container to place a flat PCB board. When the PCB board is moved to the end of the lower half groove 105a-2, the protruding structure at the end of the pulling rod 105c-12 limits the connecting structure in the middle of the flexible PCB board. At the same time, when lifting occurs, the active arm 105c-1, the driven arm 105c-2 and the hinge 105c-3 of the clamping assembly 105 form a scissors structure, and the sliding head 105c-22 will move toward the inside of the lower half groove 105a-2. Therefore, the sliding head 105c-22 and the protruding structure at the end of the pulling rod 105c-12 will clamp the connecting structure in the middle of the flexible PCB board. When the lifting continues, since the flexible PCB board is hinged, The PCB boards on both sides will sag due to the influence of gravity, so the two sides of the bendable PCB board form a certain angle, and form a folded state under the extrusion of the crimping plate 104d. When folded, the PCB boards on both sides are vertically upward. At this time, the crimping plate 104d is parallel to the PCB, and the back of the PCB is close to the scissor fork assembly 105c. Therefore, when the crimping plate 104d crimps the PCB, the scissor fork assembly 105c can provide supporting force to keep it stable. The translation rod 105c-11 and the pulling rod 105c-12 as well as the rotating head 105c-21 and the sliding head 105c-22 serve as the two ends of the scissor-shaped structure. The translation rod 105c-11 moves inward when lifting occurs, and the sliding head 105c-22 also moves in the clamping direction.

[0043] In summary, the present invention can provide a processing platform for a PCB circuit board with a flexible structure, meet the processing requirements of the flexible PCB, improve work efficiency, reduce the loss caused by the flexible PCB when using conventional equipment, improve work efficiency, and the flexible PCB is small in size, making its storage more convenient.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
