DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] The present application relates to a kind of transfer protection device for PCB line board, such as Figure 1As shown, the device includes a frame 1, inside which is a placement component 2 for supporting workpieces. At the ends of the placement component 2 are opposing positioning and protective mechanisms 3. When a workpiece is supported on the placement component 2, the positioning and protective mechanisms 3 can respectively engage with the two top corners of the workpiece and apply downward pressure to position the workpiece. The following is a detailed explanation using the production and transfer operation of the PCB circuit board 4 as an example:

[0029] Specifically, such as Figure 1 As shown, in this embodiment, the frame 1 includes a square box-shaped base 101 and a back plate 102 connected to one side of the base 101 to form an "L"-shaped structure. Multiple sets of equally spaced and parallel placement members 2 are arranged inside the base 101. It should be noted that the number of placement members 2 can be adjusted according to actual needs. Each placement member 2 has a groove for attaching to a PCB circuit board 4. In this embodiment, the placement member 2 is a concave structure made of EPE foam, with the groove at the top of the concave shape for attaching to the PCB circuit board 4. Of course, in addition to EPE foam, materials such as EVA foam or rubber can also be used.

[0030] Figure 2 A schematic diagram of the positioning and protection mechanism 3 is shown. As shown in the figure, the positioning and protection mechanism 3 has a fixed base 301 and a telescopic rod 302 whose bottom end is elastically torsionally connected to the fixed base 301. The top end of the telescopic rod 302 is also rotatably connected to a positioning clip 303 for locking the top corner of the workpiece. For example... Figure 3 As shown, the telescopic rod 302 includes a first telescopic joint 3021 and a second telescopic joint 3022, one end of which is slidably connected within the first telescopic joint 3021. A positioning clip 303 is connected to the top of the second telescopic joint 3022 via a bearing or rotatable connection. A connecting shaft 304 is connected through the bottom end of the first telescopic joint 3021. Both ends of the connecting shaft 304 are connected to the opposite surfaces of the inner wall of the fixed base 301. A torsion member 305, with both ends fixed to the fixed base 301 and the telescopic rod 302 respectively, is sleeved around the connecting shaft 304. In this embodiment, the torsion member 305 is a torsion spring, which generates elastic potential energy when the telescopic rod 302 rotates. Furthermore, it should be noted that in its natural state, the torsion member 305 keeps the telescopic rod 302 in an inward-retracted state, such as... Figure 1The second telescopic section 3022 can realize self-positioning when sliding in the first telescopic section 3021, and the self-positioning is realized by the fact that a limiting piece 3023 is adhered to the inner wall at the joint of the first telescopic section 3021 and the second telescopic section 3022, and the limiting piece 3023 is preferably a rubber pad.

[0031] Figures 4-5 As shown in the figure, when used, first, the two positioning protection mechanisms 3 are turned to open and are in the outward expansion state, at this time, the torsion pieces 305 store elastic potential energy, then one edge of the PCB circuit board 4 is clamped into the groove at the top of the placing piece 2, the two positioning protection mechanisms 3 are released, the torsion pieces 305 release the elastic potential energy, and the two positioning protection mechanisms 3 are tilted and inwardly retracted, and at the same time, the length of the telescopic rod 302 is adjusted according to the size of the PCB circuit board 4, so that the positioning clamps 303 are clamped at the top corners of the PCB circuit board 4, and since the two positioning protection mechanisms 3 form clamping on the two sides of the PCB circuit board 4 and form a triangular structure by being tilted and inwardly retracted, the two positioning protection mechanisms 3 can also generate downward pressure on the top of the PCB circuit board 4, so as to effectively limit the movement of the PCB circuit board 4 and realize effective positioning of the PCB circuit board 4, thereby realizing protection of the PCB circuit board 4 during transfer operation of the PCB circuit board 4.

[0032] Figure 6 As shown in the figure, when used, first, the two positioning protection mechanisms 3 are turned to open and are in the outward expansion state, at this time, the torsion pieces 305 store elastic potential energy, then one edge of the PCB circuit board 4 is clamped into the groove at the top of the placing piece 2, the two positioning protection mechanisms 3 are released, the torsion pieces 305 release the elastic potential energy, and the two positioning protection mechanisms 3 are tilted and inwardly retracted, and at the same time, the length of the telescopic rod 302 is adjusted according to the size of the PCB circuit board 4, so that the positioning clamps 303 are clamped at the top corners of the PCB circuit board 4, and since the two positioning protection mechanisms 3 form clamping on the two sides of the PCB circuit board 4 and form a triangular structure by being tilted and inwardly retracted, the two positioning protection mechanisms 3 can also generate downward pressure on the top of the PCB circuit board 4, so as to effectively limit the movement of the PCB circuit board 4 and realize effective positioning of the PCB circuit board 4, thereby realizing protection of the PCB circuit board 4 during transfer operation of the PCB circuit board 4.

[0033] Further, in order to improve the stability of the protective cover 5 when closed, a magnetic attraction assembly is arranged between the abutting surfaces of the protective cover 5 and the frame 1 when closed, so as to realize magnetic attraction connection between the protective cover 5 and the frame 1 when closed. Specifically, the magnetic attraction assembly comprises a first magnet embedded in the bottom surface of the protective cover 5 and a second magnet embedded in the abutting surface of the frame 1 relative to the bottom of the protective cover 5, and the magnetic properties of the second magnet and the first magnet are opposite, so that when the protective cover 5 is closed, the mutual magnetic attraction between the first magnet and the second magnet is realized, so as to realize stable closing of the protective cover 5.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
