[0027] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0028] like Figures 1 to 3 As shown, a PCBA installation and positioning tool comprises: a supporting part 1, a cover assembly 2 and a supporting part 3, wherein the supporting part 3 is arranged on the supporting part 1, and the cover assembly 2 is rotatably connected to the supporting part 3. The supporting part 1 is used to place the PCBA, and the supporting part 3 is used to support and connect the cover assembly 2, so that the cover assembly 2 can rotate on the supporting part 3, and the cover assembly 2 can cover the top of the PCBA for screw installation, thereby preventing the direct installation of screws from causing damage to the components on the PCBA or the PCBA body.

[0029] Specifically, Figures 1 to 3 As shown, the supporting part 1 includes a bottom plate 11, at least two supporting members 12 and at least one positioning member 13. The supporting member 12 can be used to support and place the PCBA, and the positioning member 13 can be used to support the cover assembly to prevent the cover assembly 2 from damaging the PCBA.

[0030] At least two supporting members 12 are vertically arranged on the upper surface of the base plate 11, wherein at least two supporting members 12 can be staggered or arranged opposite to each other according to the position of the components in the PCBA, and can be used to better support the PCBA. At least two supporting members 12 form a supporting area 121 on the top, and the supporting area 121 can be used to place the PCBA. Among them, at least two supporting members 12 are arranged to facilitate supporting the PCBA. Since the size, quantity and position of the components on different PCBAs are different, the supporting members 12 are arranged according to the size, quantity and position layout of the components on the PCBA, so that the supporting members 12 can be arranged opposite to each other, or can be staggered, and different lengths and sizes can also be set to better support the components on various PCBAs. In this embodiment, five supporting members 12 are arranged.

[0031] At least one positioning member 13 is vertically disposed on one end of the bottom plate 11, and can be used to limit the flip angle of the cover assembly 3. The positioning member 13 can be disposed at any position on the upper surface of the bottom plate. In this example, the positioning member 13 is disposed at one end of the bottom plate 11 directly opposite to the support portion 3. When the cover assembly 2 rotates around the support portion 2, the positioning member 13 abuts against one end of the cover assembly 3, so that the cover assembly 2 does not continue to rotate, thereby preventing the cover assembly 2 from being pressed down and causing damage to the PCBA.

[0032] The cover plate assembly 2 includes a connection assembly 21 and a cover plate 22. The connection assembly 21 is fixed to one end of the cover plate 22. The cover plate 22 is rotatably connected to the support portion 3 through the connection assembly 21. The cover plate 22 is also provided with a plurality of mounting holes 221 and a plurality of positioning holes 222. The plurality of mounting holes 221 are arranged facing the bottom plate 11. Therefore, when the PCBA is placed in the supporting area 121, each mounting hole 221 arranged on the cover plate 22 is aligned with the position where the screw needs to be installed on the PCBA, so that the screw is installed. The screw is installed on the PCBA through the mounting hole 221, which avoids the worker from directly installing the screw on the PCBA and avoids damage to the components caused by human collision. The screw is installed through the mounting hole 221 to ensure that the screw will not be missed.

[0033] The positions of the multiple positioning holes 222 are arranged opposite to the positioning member 13. When the cover plate 22 is turned down to cover the top of the PCBA, each positioning member 13 is engaged with each positioning hole 222 to position the cover plate 22, and also to support the cover plate 22 so that the cover plate 22 will not be pressed down to damage the PCBA. In a specific implementation, the number of positioning holes 222 and positioning members 13 can be set according to the weight of the cover plate 22, so as to support the cover plate 22 more stably. In this example, one positioning hole 322 is set, and one positioning member 13 is set.

[0034] The connecting assembly 21 includes a rotating member 211 and a connecting member 212 . The rotating member 211 is fixedly connected to the cover plate 22 , and the rotating member 211 is rotatably connected to the supporting portion 3 via the connecting member 212 .

[0035] like Figures 1 to 3 As shown, the support portion 3 is vertically arranged on one end of the bottom plate 11, wherein the support portion 3 includes at least two support members 31, and at least two support members 31 are arranged in a row on one end of the bottom plate 11. The support members 31 are used to be rotatably connected with the cover plate 22. At least two support members 31 can prevent the cover plate 22 from turning unbalanced. When the mass of the cover plate 22 is large, more than two support members 31 can be arranged for support. In this embodiment, two support members 31 are arranged.

[0036] like Figures 1 to 3 As shown, specifically, the support member 31 includes a column 311, a connection hole 312 and a stopper 313, and the connection hole 312 is opened on the top of the column 311. The connection member 212 can be inserted into the connection hole 312 of the column 311, and the rotating member 211 is rotatably connected with the column 311, so that the rotating member 211 uses the connection member 212 as a rotation axis, and the rotating member 211 can rotate on the connection member 212, thereby driving the cover plate 22 to flip.

[0037] When the PCBA is placed in the bearing area 121, the stopper 313 is fixedly installed on one side of the column 311 and is arranged opposite to the cover plate 22, wherein the stopper 213 is arranged in an "L" shape. When the cover plate 22 is flipped to 90 degrees, the stopper 313 can be used to support the cover plate 22, and the cover plate 22 can be abutted against the stopper 313. At the same time, the cover plate 22 is restricted from further flipping to prevent damage to the cover plate assembly 3 caused by excessive flipping.

[0038] like Figures 4 to 5 As shown, in one embodiment, a sleeve 2211 is further provided in each mounting hole 221, and the sleeve 2211 is a trumpet-shaped structure that is wide at the top and narrow at the bottom. The wide mouth 22111 of the sleeve 2211 is provided on the upper surface of the cover plate 22, and the narrow mouth 22112 of the sleeve 2211 passes through the mounting hole 221, extends through the lower surface of the cover plate 22, and passes through the cover plate 22. In this way, when the screw is installed through the mounting hole 221, the wide mouth 22111 of the sleeve 2211 can facilitate the screw to be placed in the sleeve 2211, and the narrow mouth 22112 of the sleeve 2211 extends through the cover plate 22, which can facilitate the accurate alignment of the screw with the position where the screw needs to be installed on the PCBA.

[0039] like Figures 1 to 3 As shown, in one embodiment, at least one group of positioning components 15 is also provided on the bottom plate 22, and at least one group of positioning components 15 is vertically arranged on the upper surface of the bottom plate 22. The positioning components 15 include two positioning members 151, and the two positioning members 151 are arranged on both sides of the bottom plate 32. In this way, the PCBA can be fixed by the positioning members 151 to prevent the movement of the PCBA, wherein the positioning members 151 can be arranged in a staggered manner or in a facing manner. In a specific implementation, the number of positioning components can be set according to the size of the PCBA. In this embodiment, one group of positioning components 15 is provided, and there are 2 positioning members 151 in total.

[0040] like Figures 1 to 3 As shown, in another embodiment, the cover plate 22 further includes a flip cover 223, which is arranged on one side of the cover plate 22 and is in the same horizontal plane as the cover plate 22 and is also parallel to the bottom plate 11. Thus, it is convenient for the staff to hold the flip cover 223 and turn the cover plate 22 over conveniently through the flip cover 223. The flip cover 223 can be arranged on the side of the cover plate 22 facing the support part 2, or on the side of the cover plate 22 adjacent to the support part 3. In this embodiment, the flip cover 223 is a plastic grip, and is arranged on the side of the cover plate 22 adjacent to the support part 3.

[0041] In summary, in a specific implementation, the rotating member 211 is flipped with the connecting member 212 as the rotating axis, so that the cover plate 22 connected to the rotating member 211 can be flipped around the connecting member 212. The cover plate 22 is lifted up by the flip cover member 223. After the cover plate 22 is flipped, it is leaned against the limit member 313, and the PCBA is placed in the supporting area 121 at the top of the supporting member 12. At this time, the PCBA is fixed by the clamping assembly 15. Then the cover plate 22 is closed, and the positioning hole 222 on the cover plate 22 is nested and positioned with the positioning member 13 on the bottom plate 11, and the cover plate 22 is positioned and supported at the same time. When the cover plate 22 is closed and positioned and fixed, the screw is placed in the sleeve 2211, and the screw slides down along the sleeve 2211 to reach the position where the screw needs to be installed on the PCBA, and then the screw is installed on the PCBA with the installation tool. Therefore, screws are installed on the PCBA through the sleeve 3211 of the cover plate 32 to ensure that the screws are not missed and the position of the PCBA installation screws can be accurately located; at the same time, the screws are installed through the sleeve 2211 to avoid the staff from directly touching the PCBA during the screw installation process, thereby preventing damage to the components on the PCBA and preventing damage to the main body of the PCBA.

[0042] like Figures 1 to 3 As shown, in one embodiment, the bottom plate 11 further includes at least one set of pull ring groups 14, the pull ring groups 14 include two pull ring members 141, and the two pull ring members 141 are arranged at opposite ends of the bottom plate 11. The pull ring members 141 can be used for portable PCBA installation and positioning tooling; when the PCBA is placed on the PCBA installation and positioning tooling and needs to be moved, the operator can use both hands to carry it through the two pull ring members 141 to prevent the PCBA from falling from the installation and positioning tooling.

[0043] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
