[0002] A circuit board is an important electronic component and a support for electronic components. During the processing of a circuit board, a bracket is required to hold the circuit board; most of the existing brackets for circuit board processing are fixedly installed on the operating table. The overall structure of the common bracket is fixed and cannot be adjusted flexibly. Since the multi-layer circuit board brackets, the trays on each layer are generally connected and fixed to the support columns by screws, resulting in inconvenient disassembly and assembly operations between the trays. Summary of the Invention

[0003] The purpose of the present invention is to provide a circuit board production bracket.

[0004] The technical problems of the present invention are mainly solved by the following technical solutions:

[0005] A circuit board production bracket includes a loading tray and an unloading tray:

[0006] A screw tube I is arranged at the middle of the inner bottom of the unloading tray. A screw rod I screwed to the screw tube I is arranged at the bottom of the loading tray, and the two ends between the loading tray and the unloading tray are also fixed by a connecting mechanism;

[0007] The connecting mechanism includes vertical plates located outside the loading tray and the unloading tray. Two groups of mounting plates located between the loading tray and the unloading tray are arranged on one side of the vertical plates. A screw tube II is fixed between the two groups of vertically corresponding mounting plates through bearings. Screw rods II are arranged at both ends of the screw tube II. Support blocks abutting against the corresponding loading tray and unloading tray are respectively arranged at the ends of the two groups of screw rods II. Grooves corresponding to the support blocks are respectively arranged at the bottom end of the loading tray and the top end of the unloading tray. A convex block extending into the corresponding groove is arranged on the support block.

[0008] As a preferred solution, support plates are arranged on the front and rear side walls inside the loading tray and the unloading tray, and U-shaped notches for fixing the end of the circuit board are uniformly arranged at the top of the support plates.

[0009] As a preferred solution, sliding openings corresponding to the support blocks are vertically arranged on the upper and lower side walls of the vertical plates. A limiting block passing through the corresponding sliding opening is arranged on one side of the support block, and the two groups of mounting plates are located between the upper and lower two groups of sliding openings.

[0010] As a preferred solution, a notch is vertically arranged on the side wall of the screw rod I, and a scale mark is arranged on the side wall at the notch of the screw rod I.

Detailed Embodiments

[0018] Next, through embodiments and in combination with the drawings, the technical solutions of the present invention will be further specifically described.

[0019] A circuit board production bracket includes a feeding tray 1 and a blanking tray 2:

[0020] In the middle of the inner bottom of the blanking tray 2, a solenoid I 3 is arranged. A screw I 4 screwed to the solenoid I 3 is arranged at the bottom of the feeding tray 1, and the two ends between the feeding tray 1 and the blanking tray 2 are also fixed through a connecting mechanism 5;

[0021] The connecting mechanism 5 includes a vertical plate 51 located outside the loading tray 1 and the unloading tray 2. On one side of the vertical plate 51, there are two groups of mounting plates 52 located between the loading tray 1 and the unloading tray 2. A screw tube II 53 is fixed between the two groups of upper and lower corresponding mounting plates 52 through bearings. Both ends of the screw tube II 53 are provided with screw rods II 54. At the ends of the two screw rods II 54, there are support blocks 55 that abut against the corresponding loading tray 1 and unloading tray 2 respectively. Grooves 56 corresponding to the support blocks 55 are respectively provided at the bottom end of the loading tray 1 and the top end of the unloading tray 2. Protrusions 57 extending into the corresponding grooves 56 are provided on the support blocks 55.

[0022] As Figure 1 , 2 shown, on the front and rear side walls in the loading tray 1 and the unloading tray 2, there are support plates 6. At the top of the support plates 6, U-shaped notches 7 for fixing the ends of the circuit boards are evenly arranged. The U-shaped notches 7 on the front and rear sides play a role in fixing the ends of the circuit boards, thereby fixing a number of circuit boards in an orderly manner in the loading tray 1 and the unloading tray 2.

[0023] As Figure 3 shown, sliding openings 8 corresponding to the support blocks 55 are vertically provided on the upper and lower side walls of the vertical plate 51. On one side of the support block 55, there is a limit block 9 passing through the corresponding sliding opening 8, and the two groups of mounting plates 52 are located between the upper and lower two sliding openings 8. Then when the screw tube II 53 is rotated to rotate on the screw rod II 54, the screw rod II 54 will drive the support block 55 to move up and down. At this time, the support block 55 drives the limit block 9 to slide in the sliding opening 8. By the way of the sliding opening 8 abutting against the limit block 9, the support block 55 is prevented from rotating together with the screw rod II 54 under the influence of the rotation of the screw rod II 54.

[0024] As Figure 4 shown, a notch 10 is vertically provided on the side wall of the screw rod I 4, and a scale mark is provided on the side wall at the notch of the screw rod I 4. When the loading tray 1 is rotated to drive the screw rod I 4 to rotate up and down in the screw tube I 3, the displacement amplitude of the loading tray 1 can be known through the scale mark at the notch.

[0025] In this embodiment, the top of the screw tube I 3 is communicated with the outside of the bottom of the unloading tray 2. A stud that abuts against the bottom end of the screw rod I 4 is screwed in the screw tube I 3, and cross grooves are provided on the upper and lower end faces of the stud. After the screw rod I 4 rotates in the screw tube I 3, the stud can be rotated upward so that while rotating in the screw tube I 3, its top abuts against the bottom end of the screw rod I 4, thereby playing a supporting role for the bottom end of the screw rod I 4 to prevent the screw rod I 4 from sliding downward in the screw tube I 3. At the same time, the bottom end of the stud will not extend to the outside of the bottom of the screw tube I 3 to prevent it from jacking up the unloading tray 2 to be suspended or warped.

[0026] Working principle of the present invention: During installation, rotate the feeding tray 1 to drive the screw I 4 to rotate within the screw tube I 3, thereby adjusting the distance between the feeding tray 1 and the discharging tray 2 to meet the production requirements. At the same time, rotate the stud so that its top end abuts against the bottom end of the screw I 4. Then, install the connecting mechanism 5. The specific steps are as follows: Place the vertical plate 51 on one side of the feeding tray 1 and the discharging tray 2. At this time, the upper and lower groups of support blocks 55 are both located between the feeding tray 1 and the discharging tray 2. Then, by rotating the screw tube II 53 to rotate within the bearing on the mounting plate 52 and simultaneously rotate on the screw II 54, the distance between the two screw II 54s inside it is enlarged. During the movement of the screw II 54, it drives the support block 55 to move, so that the upper and lower groups of support blocks 55 abut against the bottom end face of the corresponding feeding tray 1 and the top end face of the discharging tray 2. During this process, since the vertical plate 51 abuts against one end face of the support block 55, it can effectively prevent the support block 55 from rotating together with the screw II 54 under the influence of the rotation of the screw II 54. When the support block 55 contacts the corresponding feeding tray 1 and the discharging tray 2, it drives the convex block 57 to be embedded in the corresponding groove 56, and by the way that the groove 56 abuts against the convex block 57, it prevents the connecting mechanism 5 from sliding out of the distance between the feeding tray 1 and the discharging tray 2.

[0027] The disassembly steps between the feeding tray 1 and the discharging tray 2 are just the opposite. The present invention adjusts the distance between the feeding tray 1 and the discharging tray 2 by rotating the screw I 4 in the screw tube I 3 to meet the usage requirements. At the same time, the distance between the feeding tray 1 and the discharging tray 2 is fixed through the connecting mechanism 5, thereby playing a supporting role for the feeding tray 1 to improve the stability and safety between the feeding tray 1 and the discharging tray 2. The present invention can effectively adjust the distance between the feeding tray 1 and the discharging tray 2. While strengthening the connection stability between the feeding tray 1 and the discharging tray 2, it also facilitates the installation and disassembly work between the feeding tray 1 and the discharging tray 2.

[0028] The above has described the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
