[0002] PCB board is an important component of electronic equipment, and special protection measures are needed to ensure its quality and performance are not affected in the production, processing and transportation process of PCB board because of its fragile and thin texture, easy to scratch surface and internal circuit easy to be damaged.

[0003] At present, the common PCB board transportation method is mainly to place it in a paper box or plastic box, and then fill the buffer materials such as foam and bubble bag between the boards to reduce the vibration and collision in the transportation process. However, this traditional transportation method has many problems. On the one hand, when the transportation road is bumpy or subjected to a large external impact, the PCB board is easy to displace and shake in the box, which causes the mutual friction and collision between the boards, thereby causing the damage such as surface scratch and circuit breakage of the PCB board. On the other hand, when the PCB board is taken out, the PCB is easy to scratch the paper box or plastic box, so the operator often needs to spend a lot of time and effort to take it out carefully, which is not only low in efficiency, but also may cause damage to the PCB board due to improper operation in the taking-out process.

[0004] Therefore, the utility model is provided. UTILITY MODEL CONTENT

[0005] In order to solve the technical problems that the PCB board is easy to displace and shake in the box, which causes the mutual friction and collision between the boards, thereby causing the damage such as surface scratch and circuit breakage of the PCB board and the inconvenience of taking out the PCB from the plastic box, the basic concept of the technical scheme adopted by the utility model is as follows:

[0007] Each group of jacking assemblies comprises an extrusion cover, the extrusion cover is installed at the bottom of the inner groove, a top rod is movably inserted in the extrusion cover, a return spring is connected between the top rod and the extrusion cover, a rubber pad is installed at the top of the top rod, and a pressing pad is installed at the bottom of the cover plate, the rubber pad vertically corresponds to the pressing pad.

[0008] As a preferred embodiment of the utility model, an anti-skid seat is installed at the bottom of the disc seat, an outer thread is formed in the sidewall of the disc seat, a threaded groove is formed in the inner wall of the cover sleeve, and the threaded groove and the outer thread are mutually adapted.

[0010] As a preferred embodiment of the utility model, a limiting ring is fixedly installed on the cover plate, four limiting rods are installed at the bottom of the limiting ring, the lengths of the four limiting rods are less than the depth of the inner groove, four limiting grooves are uniformly formed in the side walls of the inner groove, and each limiting rod vertically corresponds to a limiting groove.

[0011] As a preferred embodiment of the utility model, the cover plate, the disc seat and the cover sleeve are made of acrylic plates.

[0012] As a preferred embodiment of the utility model, a baffle is movably inserted in the extrusion cover, one end of the baffle is connected with the ejector rod, a return spring is connected between the other end of the baffle and the inner wall of the extrusion cover, and the compression direction of the return spring is on the same line as the moving direction of the ejector rod.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0023] like Figures 1 to 4 As shown, a PCB-specific carrier includes a tray base 1 and a cover 2. The cover 2 is screwed onto the surface of the tray base 1. A cover plate 4 is rotatably mounted on the cover 2. An inner groove 14 is formed inside the tray base 1. The inner groove 14 is vertically aligned with the cover plate 4. A sponge pad is installed on the side wall of the inner groove 14. The sponge pad is used to protect the PCB board in the inner groove 14. Four sets of lifting components for lifting the PCB are installed on the inner groove 14.

[0024] Each lifting assembly includes a compression cover 9. The outer shell of the compression cover 9 is installed at the bottom of the inner groove 14. A push rod 10 is movably inserted inside the compression cover 9. A return spring 13 is connected between the push rod 10 and the compression cover 9. A rubber pad 11 is installed on the top of the push rod 10. A pressure pad 8 is installed on the bottom of the cover plate 4. The rubber pad 11 and the pressure pad 8 are vertically aligned, and a PCB board is placed between the rubber pad 11 and the pressure pad 8. When clamping and positioning the PCB board, rotating the cover sleeve 2 brings the tray 1 and the cover sleeve 2 closer together, and the rubber pad 11 on the push rod 10 and the pressure pad 8 closer together, thereby clamping the PCB board placed between them, thus ensuring the stability of the PCB board during transportation. After the cover sleeve 2 and the tray 1 are separated later, the return spring 13 inside the compression cover 9 can drive the push rod 10 to move upward, and finally the PCB board on the push rod 10 is pushed out from the inner groove 14 of the tray 1, making it easier for the operator to pick up the PCB board later, making the operation simpler. The rubber pad 11 and the pressure pad 8 are pressed at the position on the PCB board where there are no electronic components.

[0025] like Figures 1 to 4 As shown, in a specific embodiment, an anti-slip seat 17 is installed at the bottom of the disc base 1. The anti-slip seat 17 mainly serves to prevent slipping. The side wall of the disc base 1 is provided with an external thread 6, and the inner wall of the cover 2 is provided with a threaded groove 7. The threaded groove 7 and the external thread 6 are compatible with each other, and the external thread 6 and the threaded groove 7 can be easily screwed together.

[0026] like Figures 1 to 4As shown, further, the cover sleeve 2 side wall is symmetrically provided with a pair of protrusions 5, a pair of protrusions 5 and cover sleeve 2 connection is chamfered, the protrusions 5 surface is provided with anti-skid groove, through the protrusions 5 convenient operator to rotate the cover sleeve 2, so that the cover sleeve 2 is more easily rotated, convenient to disassemble and install.

[0027] As shown in the figure, Figures 1 to 4 Further, the cover plate 4 is fixedly provided with a limiting ring 3, and the limiting ring 3 is provided with four limiting rods 15 at the bottom. The length of the four limiting rods 15 is less than the depth of the inner groove 14, and the inner groove 14 is uniformly provided with four limiting grooves 16 on the side wall. Each limiting rod 15 vertically corresponds to the limiting groove 16. When the limiting rod 15 is inserted in the limiting ring 3, the entire limiting rod 15 will lock the rotating direction of the limiting ring 3 and the cover plate 4, so that the cover plate 4 can only be vertically slid, ensuring that the rubber pad 11 and the pressing pad 8 can be vertically corresponded.

[0028] As shown in the figure, Figures 1 to 4 Further, the cover plate 4, the disc seat 1 and the cover sleeve 2 are made of acrylic plate, which is convenient for the operator to observe the state of the PCB board in time.

[0029] As shown in the figure, Figures 1 to 4 Further, the inside of the extrusion cover 9 is movably provided with a baffle 12, one end of the baffle 12 is connected with the top rod 10, and the other end of the baffle 12 is connected with the inner wall of the extrusion cover 9 through a reset spring 13. The compression direction of the reset spring 13 is on the same straight line with the moving direction of the top rod 10. When the PCB board and the top rod 10 move downward, the baffle 12 at the end of the top rod 10 slides downward along the extrusion cover 9, and at this time the reset spring 13 at the bottom of the baffle 12 is compressed. Through the reset spring 13, the top rod 10 is conveniently pushed out in the later period, that is, after the disc seat 1 and the cover sleeve 2 are separated, the reset spring 13 pushes the top rod 10 outward, so that the PCB board moves out of the inner groove 14.

[0030] The implementation principle of a special PCB disc is as follows:

[0031] First, the operator needs to place the PCB board above the rubber pad 11 of the top rod 10, and needs to correspond the rubber pad 11 with the edge of the PCB board, and the operator needs to control the size of the PCB board to be less than the size of the disc seat 1.

[0032] Then the operator needs to rotate the cover sleeve 2, so that the disc seat 1 and the cover sleeve 2 are screwed and connected, before the cover sleeve 2 rotates, the operator also needs to position the limiting ring 3 on the cover plate 4, and insert the limiting rod 15 on the limiting ring 3 into the limiting groove 16, so that when the cover sleeve 2 rotates downward, the limiting rod 15, the limiting ring 3 and the cover plate 4 at this time will not rotate, but the cover plate 4 as a whole slides downward, when the cover plate 4 moves downward, the cover plate 4 at this time can be extruded with the PCB board above the rubber pad 11, and with the continuous downward movement of the cover plate 4, the PCB board can finally slide into the sponge pad in the inner recess 14 of the disc seat 1, and finally the rubber pad 11 and the pressing pad 8 can clamp and fix the PCB board, ensuring the stability of the PCB board during transportation. And in the process of moving the PCB board downward, the top rod 10 moves downward at this time, the baffle 12 at the end of the top rod 10 slides downward along the extrusion cover 9, and the reset spring 13 at the bottom of the baffle 12 is compressed at this time, which facilitates the subsequent ejection operation, that is, after the disc seat 1 and the cover sleeve 2 are separated, the reset spring 13 pushes the top rod 10 outward, so that the PCB board moves out of the inner recess 14, which is convenient for later taking.
