Description

Technical Field

[0001] This utility model relates to the field of material tray technology, specifically a material tray for circuit board processing. Background Technology

[0002] Circuit boards serve as the support and electrical connection carrier for electronic components. They consist of pads, wires, vias, and insulating substrates, and are integrated using printing technology. Their core function is to miniaturize and standardize complex circuits, thereby improving the reliability and production efficiency of electronic devices.

[0003] A search revealed CN217805914U, which discloses a circuit board material tray, including a tray assembly. An adjusting frame is fixedly connected to the bottom of the tray assembly, and a miniature cylinder is fixedly connected to the back of the inner cavity of the adjusting frame. A transmission rod is fixedly connected to the output end of the miniature cylinder, and a trapezoidal block is fixedly connected to the outer side of the transmission rod. A wheel baffle is slidably connected to the inner side of the top of the trapezoidal block, and the top of the wheel baffle extends through to the top of the tray assembly. Circuit board materials are placed on the top of the tray assembly. Connecting blocks are fixedly connected to both the top and bottom of the miniature cylinder. This invention achieves the effect of preventing material slippage. This circuit board material tray solves the problem that existing trays simply place circuit board materials directly on top of the tray, without any protective structure on the top, making slippage easy during handling and movement, leading to quality problems and affecting the yield rate.

[0004] However, the existing trays can only limit the movement of square circuit boards to prevent them from slipping, and are not convenient for limiting the movement of round circuit boards to prevent them from slipping, so they need to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide a material tray for circuit board processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a material tray for circuit board processing, comprising a base and limiting strips, wherein each of the four corners of the upper surface of the base is fixedly connected to a column, and a tray plate is fixedly connected to the upper end of the column, and the surface of the tray plate is provided with multiple square holes in a circular array, the limiting strips are slidably connected to the inner wall of the square holes, and the bottom of the limiting strips is rotatably connected to rollers, and the surface of the base is provided with an adjustment mechanism for driving multiple limiting strips to rise and fall simultaneously.

[0007] The adjustment mechanism includes an adjustment seat, which is rotatably connected to the center of the base surface. The surface of the adjustment seat has an annular groove, and the inner wall of the annular groove is fixedly connected to a plurality of push plates corresponding to the square holes. The upper surface of the push plate is inclined, and the inclined surface abuts against the roller.

[0008] Preferably, the number of square holes is at least four, and the number of limiting strips is the same as the number of square holes.

[0009] Preferably, a servo motor is fixedly connected to the surface of the base, a drive gear is fixedly connected to the output end of the servo motor, and external teeth are provided on the outer surface of the adjusting seat, with the drive gear and the external teeth meshing with each other.

[0010] Preferably, a rubber anti-collision plate is fixedly connected to the surface of the limiting strip.

[0011] Preferably, the lower surface of the limiting strip is provided with a T-shaped through groove, a wheel rod is fixedly connected to the inner wall of the square hole, the end of the wheel rod is rotatably connected to a limiting wheel, and the limiting wheel is located inside the T-shaped through groove.

[0012] Preferably, foot pads are fixedly connected to the four corners of the lower surface of the base.

[0013] Beneficial effects

[0014] This utility model provides a material tray for circuit board processing, which has the following advantages:

[0015] 1. This material tray for circuit board processing, through the setting of an adjustment mechanism, can drive multiple push plates to rotate by rotating the adjustment seat. The inclined surface of the push plate abuts against the rollers, and the square holes limit the limit strips. This allows multiple limit strips to rise synchronously. By limiting the four sides of the square or round circuit board through multiple limit strips, the square or round circuit board can be effectively prevented from slipping, thereby ensuring the safety of the circuit board during transportation.

[0016] 2. The material tray for circuit board processing uses multiple limiting strips to limit the perimeter of square or round circuit boards, effectively improving the fixing effect of the circuit boards and effectively preventing the circuit boards from sliding in the front-to-back direction compared with existing technologies.

[0017] 3. The material tray for circuit board processing is equipped with a T-shaped through groove, a wheel rod, and a limiting wheel. The rotation of the limiting wheel reduces the friction between the limiting strip and the square hole, thus facilitating the up-and-down movement of the limiting strip. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a material tray for circuit board processing, including a base 1 and limiting strips 2. Columns 3 are fixedly connected to the four corners of the upper surface of the base 1. A tray plate 4 is fixedly connected to the upper end of each column 3. Multiple square holes 5 are arranged in a circular array on the surface of the tray plate 4. The limiting strips 2 are slidably connected to the inner wall of the square holes 5. Rollers 6 are rotatably connected to the bottom of the limiting strips 2. An adjustment mechanism is provided on the surface of the base 1 to drive the multiple limiting strips 2 to move up and down simultaneously. The adjustment mechanism includes an adjustment seat 7, which is rotatably connected to the center position of the surface of the base 1. An annular groove 8 is provided on the surface. Multiple push plates 9 corresponding to square holes 5 are fixedly connected to the inner wall of the annular groove 8. The upper surface of the push plate 9 is inclined and abuts against the roller 6. By setting an adjustment mechanism, the adjustment seat 7 can be rotated to drive the multiple push plates 9 to rotate. The inclined surface of the push plate 9 abuts against the roller 6 and, together with the square hole 5, limits the limit strip 2. The multiple limit strips 2 can rise synchronously. By limiting the square circuit board or the circular circuit board around the perimeter through the multiple limit strips 2, the square circuit board or the circular circuit board can be effectively prevented from slipping, thereby ensuring the safety of the circuit board during transportation.

[0025] The minimum number of square holes 5 is four, and the number of limiting strips 2 is the same as the number of square holes 5. By using multiple limiting strips 2 to limit the perimeter of the square or round circuit board, the fixing effect of the circuit board is effectively improved. Compared with the existing technology, it effectively prevents the circuit board from sliding in the front and back directions.

[0026] A servo motor 10 is fixedly connected to the surface of the base 1. A drive gear 11 is fixedly connected to the output end of the servo motor 10. An external tooth 12 is provided on the outer surface of the adjustment seat 7. The drive gear 11 and the external tooth 12 mesh with each other. The servo motor 10 can drive the drive gear 11 to rotate. The meshing transmission between the drive gear 11 and the external tooth 12 can drive the adjustment seat 7 to rotate.

[0027] A rubber anti-collision plate 13 is fixedly connected to the surface of the limiting strip 2. By setting the rubber anti-collision plate 13, hard contact between the circuit board and the limiting strip 2 can be effectively avoided.

[0028] The lower surface of the limiting strip 2 is provided with a T-shaped through groove 14. A wheel rod 15 is fixedly connected to the inner wall of the square hole 5. The end of the wheel rod 15 is rotatably connected to a limiting wheel 16, and the limiting wheel 16 is located inside the T-shaped through groove 14. By setting the T-shaped through groove 14, the wheel rod 15 and the limiting wheel 16, the friction between the limiting strip 2 and the square hole 5 can be reduced by rotating the limiting wheel 16, thereby facilitating the up and down movement of the limiting strip 2.

[0029] Foot pads 17 are fixedly connected to the four corners of the lower surface of the base 1, which can support the base 1.

[0030] Working principle: When the material pallet for circuit board processing is in use, the circuit board is first placed in the center of the upper surface of the pallet plate 4. Then, the servo motor 10 drives the drive gear 11 to rotate. The drive gear 11 meshes with the outer side, thereby driving the adjustment seat 7 to rotate. The rotation of the adjustment seat 7 drives multiple push plates 9 to rotate. The inclined surface of the push plate 9 abuts against the roller 6, and the square hole 5 limits the limit strip 2. This allows multiple limit strips 2 to rise synchronously. By limiting the square or round circuit board around its perimeter through multiple limit strips 2, the square or round circuit board can be effectively prevented from slipping, thus ensuring the safety of the circuit board during transportation.
