Utility Model Content

[0004] In order to solve the shortcoming of the existing PCBA carrier being troublesome to disassemble and assemble, the utility model provides a split PCBA carrier which is convenient for disassembly and assembly.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A split PCBA carrier includes a base plate, a cover plate and multiple spinning parts. The base plate is provided with a first rectangular groove running through the upper and lower sides. Support blocks for supporting the PCBA are fixedly connected to the four corners of the first rectangular groove. At least two magnetic columns that can adsorb the cover plate are fixedly connected to the upper side of the base plate. A limiting groove adapted to the magnetic column is provided on the lower side of the cover plate. The cover plate is covered on the base plate, and the magnetic column is inserted into the limiting groove. A second rectangular groove is provided on the cover plate. The edge of the second rectangular groove presses the edge of the PCBA. At least two spinning parts are provided and are arranged on opposite sides of the base plate. The spinning parts include a mounting column and a rotating plate. The mounting column is vertically fixedly connected to the upper side of the base plate. One end of the rotating plate is rotatably connected to the mounting column, and the other end of the rotating plate is abutted against the upper side of the cover plate.

[0007] Through the above arrangement, firstly, the cover can be temporarily fixed by the magnetic column, which facilitates the initial covering of the cover on the PCBA; secondly, the edge of the cover can be pressed after the rotating plate is rotated to prevent the cover from loosening from the PCBA.

[0008] Furthermore, the lower end of the mounting column is threadedly connected to the upper side of the base plate, and the spinning part also includes a rotating sleeve and a spring. The rotating sleeve is coaxially connected to the mounting column and can slide along the axis of the mounting column. One end of the rotating plate is fixedly connected to the rotating sleeve, and the spring is sleeved on the mounting column. The upper end of the spring is connected to the upper end of the mounting column, and the lower end of the spring is against the upper side of the rotating sleeve.

[0009] With the above arrangement, the rotating plate is rotatably connected to the mounting post via the rotating sleeve. The spring applies downward pressure to the cover plate through the rotating sleeve and rotating plate, preventing the pressure plate from applying excessive pressure to the PCBA and causing damage to the PCBA. In addition, the rotating sleeve and rotating plate can slide up and down along the mounting post, making it convenient to clamp PCBAs of different thicknesses.

[0010] Furthermore, a groove is provided on the upper side of the edge of the cover plate, the side wall of the groove is an arc-shaped surface coaxial with the mounting column, and the rotating plate abuts against the bottom of the groove.

[0011] Furthermore, the spinning component also includes a toggle plate, which is fixedly connected to the upper side of one end of the rotating plate away from the mounting column.

[0012] Through the above arrangement, it is convenient to rotate the rotating plate by hand through the toggle plate.

[0013] Furthermore, the cover plate is rectangular, and four spinning parts are provided near the four corners of the cover plate.

[0014] Through the above arrangement, the stability of the cover is increased.

[0015] Furthermore, the base plate is rectangular, and the PCBA carrier also includes three limiting columns arranged at the three corners of the base plate. The cover plate is provided with three limiting holes adapted to the limiting columns, and the limiting columns pass through the limiting holes.

[0016] Through the above arrangement, on the one hand, the stability of the cover plate is further increased, and on the other hand, the cover plate is prevented from rotating in the wrong direction.

[0017] Furthermore, the number of the first rectangular grooves and the second rectangular grooves are both six, and they are arranged in a matrix on the bottom plate and the cover plate respectively.

[0018] Through the above configuration, the PCBA carrier of the present application can coat six PCBAs at one time, thereby improving coating efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The technical solution of the present invention will be further specifically described below with reference to embodiments and in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a split PCBA carrier includes a base plate 3, a cover plate 4 and a plurality of spinning parts 5. The base plate 3 is provided with a first rectangular groove 6 running through the upper and lower sides. The four corners of the first rectangular groove 6 are fixedly connected to support blocks 8 for supporting PCBA7. At least two magnetic columns 9 that can adsorb the cover plate 4 are fixedly connected to the upper side of the base plate 3. A limiting groove (not shown in the figure) adapted to the magnetic column 9 is provided on the lower side of the cover plate 4. The cover plate 4 covers the base plate 3, and the magnetic column 9 is inserted into the limiting groove. A second rectangular groove 10 is provided on the cover plate 4. The edge of the second rectangular groove 10 presses the edge of the PCBA7. At least two spinning parts 5 are provided and are arranged on opposite sides of the base plate 3. The spinning part 5 includes a mounting column 51 and a rotating plate 52. The mounting column 51 is vertically fixedly connected to the upper side of the base plate 3. One end of the rotating plate 52 is rotatably connected to the mounting column 51, and the other end of the rotating plate 52 is against the upper side of the cover plate 4.

[0026] Through the above arrangement, first, the cover plate 4 can be temporarily fixed by the magnetic column 9, which facilitates the initial covering of the cover plate 4 on the PCBA7. Second, after the rotating plate 52 rotates, the edge of the cover plate 4 can be pressed to prevent the cover plate 4 from loosening from the PCBA7.

[0027] In this application, the PCBA7 to be coated is basically rectangular and slightly smaller than the first rectangular groove 6, which makes it easy to put the PCBA7 into the first rectangular groove 6. The support blocks 8 on the four corners of the first rectangular groove 6 support the four corners of the PCBA7 to prevent the PCBA7 from falling downward from the first rectangular groove 6 and prevent the PCBA7 from shaking left and right in the first rectangular groove 6. The lower side of the PCBA7 can be coated through the first rectangular groove 6. Initially, the free end of the rotating plate 52 is outward, which makes it easy to cover the cover plate 4 on the PCBA7. The size of the second rectangular groove 10 is The size is slightly smaller than that of PCBA7. The cover plate 4 is covered on PCBA7. The magnetic column 9 is inserted into the limit groove to locate the position of the cover plate 4 to prevent the cover plate 4 from shifting. The magnetic column 9 absorbs the cover plate 4 to temporarily fix the cover plate 4. The edge of the second rectangular groove 10 is against the edge of the PCBA7 to prevent the PCBA7 from falling out of the first rectangular groove 6. The upper side of the PCBA7 can be coated through the second rectangular groove 10. The rotating plate 52 is rotated inward to the upper side of the cover plate 4. The rotating plate 52 presses the upper side of the cover plate 4 to prevent the cover plate 4 from detaching from the upper side of the PCBA7. Figure 1 As shown, at this point, the base plate 3 and the cover plate 4 clamp the PCBA7, completing the fixation of the PCBA7 and facilitating the coating of the PCBA7. After the coating is completed, the cover plate 4 can be removed from the PCBA7 by simply rotating the rotating plate 52 outward, which is very convenient and quick.

[0028] As an implementation method, the lower end of the mounting column 51 is threadedly connected to the upper side of the base plate 3, and the spinning part 5 also includes a rotating sleeve 53 and a spring 54. The rotating sleeve 53 is coaxially rotatably connected to the mounting column 51 and can slide along the axis of the mounting column 51. One end of the rotating plate 52 is fixedly connected to the rotating sleeve 53, and the spring 54 is sleeved on the mounting column 51. The upper end of the spring 54 is connected to the upper end of the mounting column 51, and the lower end of the spring 54 is against the upper side of the rotating sleeve 53.

[0029] Through the above arrangement, the rotating plate 52 is rotatably connected to the mounting post 51 through the rotating sleeve 53, and the spring 54 applies downward pressure to the cover plate 4 through the rotating sleeve 53 and the rotating plate 52 to prevent the pressure plate from exerting excessive pressure on the PCBA7 and causing damage to the PCBA7; in addition, the rotating sleeve 53 and the rotating plate 52 can slide up and down along the mounting post 51, making it convenient to clamp PCBA7 of different thicknesses.

[0030] The rotating plate 52 and rotating sleeve 53 of the present application are integrally formed. The lower end of the mounting post 51 is provided with a threaded structure, which facilitates the threaded installation of the spring 54 and the rotating sleeve 53 on the upper side of the base plate 3. The upper end of the mounting post 51 is fixedly connected to a support head, which facilitates the abutment of the spring 54. Manually rotating the rotating plate 52, the rotating plate 52 rotates around the axis of the mounting post 51, and the rotating plate 52 can be easily pressed against the cover plate 4 or removed from the cover plate 4. After the rotating plate 52 is rotated outward and separated from the cover plate 4, the lower side of the rotating sleeve 53 abuts against the base plate 3, and the spring 54 is in a free state. After the rotating plate 52 is rotated inward to press the cover plate 4, the spring 54 is slightly compressed to press the cover plate 4.

[0031] As an implementation method, a groove 11 is provided on the upper side of the edge of the cover plate 4 , the side wall of the groove 11 is an arc-shaped surface coaxial with the mounting column 51 , and the rotating plate 52 abuts against the bottom of the groove 11 .

[0032] As an implementation method, the spinning component 5 further includes a toggle plate 55 , which is fixedly connected to the upper side of an end of the rotating plate 52 away from the mounting post 51 .

[0033] Through the above arrangement, it is convenient to rotate the rotating plate 52 by hand through the toggle plate 55 .

[0034] As an implementation manner, the cover plate 4 is rectangular, and four spin-formed parts 5 are provided and close to the four corners of the cover plate 4 .

[0035] Through the above arrangement, the stability of the cover plate 4 is increased.

[0036] As an implementation method, the base plate 3 is rectangular, and the PCBA carrier also includes three limiting columns 12 arranged at the three corners of the base plate 3. The cover plate 4 is provided with three limiting holes 13 adapted to the limiting columns 12, and the limiting columns 12 pass through the limiting holes 13.

[0037] Through the above arrangement, on the one hand, the stability of the cover plate 4 is further increased, and on the other hand, the cover plate 4 is prevented from rotating in the wrong direction.

[0038] The limiting groove of the present application can help distinguish the front and back sides of the cover 4, and the three limiting columns 12 can limit the angle of the cover 4, so that the cover 4 can be covered on the PCBA7 at a fixed angle, preventing the cover 4 from covering the wrong side and damaging the PCBA7.

[0039] As an implementation manner, the number of the first rectangular grooves 6 and the number of the second rectangular grooves 10 are both six, and they are arranged in a matrix on the bottom plate 3 and the cover plate 4 respectively.

[0040] Through the above-mentioned setting, the PCBA carrier of the present application can coat six PCBA7s at one time, thereby improving the coating efficiency.
