Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, and more specifically, to a buffer device for circuit board pressing. Background Technology

[0002] A circuit board, also known as a PCB, is an insulating substrate on which fine copper wires, as thin as hair, are etched. Thousands of metallized holes are then drilled to solder and fix components such as resistors, capacitors, and chips according to the circuit diagram, enabling the transmission of current and signals. At the same time, it provides mechanical support for the entire device and is the core carrier of all electronic systems such as mobile phones, computers, automobiles, and spacecraft.

[0003] Circuit boards need to be cushioned during the lamination process. Most existing systems use soft pads for cushioning, but these pads have a short lifespan and need to be replaced frequently. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a buffer device for circuit board pressing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a buffer device for circuit board pressing, comprising a base, a plurality of vertical rods fixedly connected to the base, a ring block fixedly connected to each of the plurality of vertical rods, a spring sleeved on each of the plurality of vertical rods, one end of each of the plurality of springs fixedly connected to the plurality of ring blocks, the other end of each of the plurality of springs fixedly connected to a support plate, a sliding sleeve slidably connected to each of the plurality of vertical rods, a horizontal arm fixedly connected to each of the plurality of sliding sleeves, and the horizontal arm fixedly connected to a surrounding plate, the surrounding plate being sleeved on the support plate.

[0006] Preferably, an upper magnet is embedded in the lower end face of each ring block, and a lower magnet is embedded in the upper end face of each sliding sleeve, and the upper magnet and the lower magnet attract each other.

[0007] Preferably, the side panels have notches on both sides.

[0008] Preferably, the base is fixedly connected to multiple slide rails, each slide rail is slidably connected to a slide block, each slide block is hinged to a support rod, and the end of each support rod away from the slide block is hinged to a support plate.

[0009] Preferably, a top column is fixedly connected to the base.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. The pressure-bearing tray first compresses multiple springs and then contacts multiple vertical bars, thus buffering the pressure through multiple springs. Compared with existing padding buffers, springs have a longer service life. After buffering, multiple vertical bars support the tray, allowing the circuit board on the tray to withstand sufficient pressure. 2. After pressing, the tray is pushed upward by multiple springs to reset, while the surrounding plate is pressed down to a lower position. At this time, the upper end of the tray is higher than the upper end of the surrounding plate, making it easier to remove the circuit board from the tray.

[0017] Reference Figures 1 to 4 This utility model provides a technical solution: a buffer device for circuit board pressing, including a base 1, a plurality of vertical rods 2 fixedly connected to the base 1, a ring block 3 fixedly connected to each of the plurality of vertical rods 2, a spring 4 sleeved on each of the plurality of vertical rods 2, one end of each of the plurality of springs 4 fixedly connected to the plurality of ring blocks 3, and the other end of each of the plurality of springs 4 fixedly connected to a support plate 5, a sliding sleeve 6 slidably connected to each of the plurality of vertical rods 2, a horizontal arm 7 fixedly connected to each of the plurality of sliding sleeves 6, and a surrounding plate 8 fixedly connected to each of the plurality of horizontal arms 7, which is sleeved on the support plate 5; like Figure 3 and Figure 4 The lower end of the spring 4 is supported by the ring block 3 on the vertical rod 2. Multiple springs 4 can support the support plate 5. In the natural state, the upper end of the spring 4 is higher than the upper end of the vertical rod 2, so that the support plate 5 does not contact the vertical rod 2. The sliding sleeve 6 can slide along the vertical rod 2. Multiple sliding sleeves 6 support the surrounding plate 8 through the horizontal arm 7 on them. In the initial state, the upper end of the surrounding plate 8 is higher than the upper end of the support plate 5. The circuit board to be pressed can be placed on the support plate 5, and the circuit board is restricted and positioned by the surrounding plate 8, which facilitates the multi-layer alignment of the circuit board. like Figure 1 and Figure 3During the pressing process, the pressing device presses down on the enclosure 8 and the support plate 5. The enclosure 8 moves downward along the vertical rod 2 through multiple sliding sleeves 6, allowing the circuit board on the support plate 5 to be pressed smoothly. The pressed support plate 5 first compresses multiple springs 4 and then contacts multiple vertical rods 2, thus buffering the pressing process through multiple springs 4. Compared with the existing padding buffer, the springs 4 have a longer service life. After the buffering is completed, the support plate 5 is supported by multiple vertical rods 2, so that the circuit board on the support plate 5 can withstand sufficient pressure. After pressing, the support plate 5 is pushed upward by multiple springs 4 to reset, while the surrounding plate 8 is pressed down to a lower position. At this time, the upper end of the support plate 5 is higher than the upper end of the surrounding plate 8, which makes it easier to remove the circuit board on the support plate 5. Then the surrounding plate 8 is manually lifted to reset. The sliding sleeve 6 and the vertical rod 2 have a certain frictional resistance, which allows the height of the surrounding plate 8 to be maintained without applying external force.

[0018] Specifically, each of the ring blocks 3 has an upper magnet 9 embedded in its lower end face, and each of the sliding sleeves 6 has a lower magnet 10 embedded in its upper end face. The upper magnet 9 and the lower magnet 10 attract each other. like Figure 3 and Figure 4 The enclosure 8 is lifted upwards, causing the lower magnet 10 and the upper magnet 9 to come into contact and attract each other, thereby further maintaining the height of the enclosure 8.

[0019] Specifically, the enclosure 8 has notches 14 on both sides to facilitate manual lifting of the enclosure 8.

[0020] Specifically, the base 1 is fixedly connected to a plurality of slide rails 11, each slide rail 11 is slidably connected to a slide block 12, each slide block 12 is hinged to a support rod 13, and the end of each support rod 13 away from the slide block 12 is hinged to the support plate 5. like Figure 2 and Figure 3 Multiple struts 13 provide auxiliary support for the pallet 5. When the pallet 5 is raised or lowered, the struts 13 can drive the slide block 12 to slide along the slide rail 11.

[0021] Specifically, a top post 15 is fixedly connected to the base 1, such as... Figure 2 and Figure 3 When the support plate 5 comes into contact with multiple vertical bars 2, the support plate 5 will also come into contact with the top column 15, thereby further supporting the support plate 5.

[0022] Working principle: During the pressing process, the pressing device presses down on the enclosure 8 and the support plate 5. The enclosure 8 moves downward along the vertical rod 2 through multiple sliding sleeves 6, allowing the circuit board on the support plate 5 to be pressed smoothly. The pressed support plate 5 first compresses multiple springs 4 and then contacts multiple vertical rods 2, thus buffering the pressing process through multiple springs 4. Compared with existing padding buffers, springs 4 have a longer service life. After the buffering is completed, multiple vertical rods 2 support the support plate 5, allowing the circuit board on the support plate 5 to withstand sufficient pressure.

[0023] It should be noted that the standard parts used in this application can all be purchased from the market, and the specific connection methods of each part are all conventional methods such as bolts, rivets, and welding that are mature in the existing technology. Furthermore, the machinery, parts, and equipment all adopt conventional models in the existing technology, and will not be described in detail here.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
