AI Technical Summary
In existing technologies, high-power vibrators can easily cause the edges of PCB boards to crack and warp during the PCB copper plating process, affecting the lamination quality of subsequent processes and causing equipment damage.
A shockproof structure for a PCB copper plating hanging basket is designed. By setting guide rods, support parts and shockproof plates inside the hanging basket, the contact area between the PCB board and the hanging basket is increased. The sliding structure is used to adjust the accommodating space to adapt to different board sizes and reduce single-point stress.
While maintaining the copper plating effect, this method prevents PCB edge cracking and warping, protects equipment, and improves the lamination quality and equipment lifespan of subsequent processes.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of PCB copper deposition technology, especially relates to a PCB copper deposition hanging basket shockproof structure. BACKGROUND
[0002] In order to prevent the hole breakage (or poor backlight) of the bubble generated in the hole of the gantry copper deposition PCB, a vibration device is usually installed in the related chemical tank of the gantry copper deposition line. The power of the vibrator is between 30W and 75W. In order to increase the vibration effect, the manufacturer usually selects a vibrator greater than 50W, so as to shake the bubbles in the hole of the PCB immersed in the chemical tank, and achieve good chemical copper deposition effect in the hole. However, when the high-power vibrator vibrates violently, it is easy to directly shake the PCB board edge inserted on the shelf, causing the PCB board edge to be cracked and sharp, resulting in the top breakage of the pressing film machine and the wrinkling of the pressing film in the subsequent process line process. SUMMARY
[0003] In order to solve the above problems, the technical scheme provides a PCB copper deposition hanging basket shockproof structure.
[0004] In order to achieve the above purpose, the technical scheme is as follows:
[0005] A PCB copper deposition hanging basket shockproof structure, comprising two oppositely arranged guide rods, a connecting rod is arranged between the guide rods, a first support portion is arranged on one side of the guide rod, and a second support portion is oppositely arranged on the other side, a containing space for containing a PCB is formed between the first support portion and the second support portion, and a shockproof plate is arranged on one side of the first support portion.
[0006] In some embodiments, the shockproof plate is a steel plate with a thickness of 2-4mm and a width of 50-80mm.
[0007] In some embodiments, the first support portion is close to or away from the second support portion through a sliding structure.
[0008] In some embodiments, the sliding structure comprises a screw rod rotatably connected to the second support portion, and one end of the screw rod is threadedly connected with the first support portion.
[0009] In some embodiments, one end of the screw rod is provided with a recess, and the second support portion is provided with a bearing matched with the recess.
[0010] In some embodiments, the guide rod is provided with an extension rod, and the extension rod is provided with a connecting sleeve.
[0011] The application has the following beneficial effects:
[0012] The application is a kind of anti-collision structure, which is applied in the hanging basket, and the PCB board is supported by the distance between the first support part and the second support part to carry out copper sinking. Since the first support part is provided with a shockproof plate on one side, the contact area of the PCB board and the hanging basket is increased, and the single-point stress of the PCB board is reduced to prevent the board edge from being broken and warped.

[0016] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the following will further describe the present application in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.
[0017] Please refer to Figures 1-2 , a kind of PCB copper sinking hanging basket shockproof structure, including two oppositely arranged guide rods 1, connecting rod 2 is provided between the guide rod 1, the guide rod 1 one side is equipped with first support part 3, the other side is provided with second support part 4, the first support part 3 and second support part 4 form the accommodation space for accommodating PCB board between them, the first support part 3 one side is equipped with shockproof plate 5.
[0018] In specific implementation, the present application is installed in the hanging basket, the hanging basket structure is shown in patent number CN2018200581751, before the original hanging basket is not equipped with steel plate, copper sinking plate often appears broken board edge, and the board edge is warped and sharp when film pressing machine is pressed in the later process, and the line process film pressing machine roller needs to be replaced every half month, the present application can prevent the back light effect in the copper sinking hole from being damaged, and can prevent the back light effect in the copper sinking hole from being damaged, and can prevent the back light effect in the copper sinking hole from being damaged.
[0019] According to the principle that the greater the stress area is, the less the pressure is, the contact area of the PCB board and the hanging basket is increased, so that the PCB single-point contact hanging basket is not damaged due to uneven stress, and the PCB board edge is not damaged. Under the premise of ensuring the excellent quality of PCB copper sinking process (i.e. back light effect ≥ 9 levels), the PCB board is also protected from being damaged by vibration.
