Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing technology, and in particular to a fast and simple solder mask screen printing nail bed device. Background Technology

[0002] In the PCB manufacturing process, solder mask printing involves coating the PCB surface with solder mask ink to cover non-soldering areas, preventing solder from flowing into non-pad areas during the soldering process, thereby avoiding solder bridges and short circuits. Between dense IC pins and pads, solder mask bridges can effectively isolate the pads and prevent short circuits caused by solder flow.

[0003] In the PCB solder mask screen printing process, the fabrication of the nail bed is one of the key links affecting production efficiency and product quality. The traditional method of fabricating the nail bed usually involves fixing individual nails to predetermined positions one by one with adhesive tape. This method is not only inefficient, but also prone to problems such as nail displacement and damage to the board surface, which seriously affects production efficiency and product quality.

[0004] Therefore, this utility model proposes a fast and simple nail bed device for solder resist screen printing. Utility Model Content

[0005] The purpose of this invention is to provide a fast and convenient nail bed device for solder resist screen printing to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fast and simple solder resist screen printing stapler device includes a stapler plate with three sets of sliding grooves arranged in a linear array inside the stapler plate. Several sets of pins are slidably fitted inside the sliding grooves, and each pin has a staple base fixedly connected to its bottom end. Several sets of square grooves are evenly formed at the bottom of the sliding grooves, and limit blocks are provided inside the square grooves. A connecting block is fixedly connected to the bottom end of the limit block, and the bottom end of the connecting block is fixedly connected to an adjustment block.

[0008] Furthermore, the interior of the nail bed board is provided with several sets of square grooves, and the size of the square grooves is fitted into the outer wall of the nail seat, and the square grooves are connected to the sliding grooves.

[0009] Furthermore, the nail holder has a slot inside, and the bottom end of the slot is fitted with the outer wall of the limiting block. The top end of the slot is circular, and the diameter of the circle is slightly larger than the length of the limiting block.

[0010] Furthermore, the bottom end of the nail bed board is provided with several sets of round holes, and each round hole is movably fitted with an adjusting block. The adjusting block is cuboid in shape and has a long groove inside.

[0011] Furthermore, a number of sets of magnetic blocks are fixedly connected to the bottom end of the nail bed board, and the sets of magnetic blocks are arranged in a linear array at the bottom of the nail bed board.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. By sliding the corresponding pins and pin holders at predetermined positions, the pin holders are connected to the pin bed board. Then, by rotating the adjusting block, the connecting block drives the limiting block to limit and fix the pin holders. This ensures that the position of the pins remains stable during use, ensuring that the pins maintain verticality and positional accuracy during the silkscreen printing process. This avoids uneven solder mask thickness or silkscreen pattern deviation caused by pin displacement, and prevents the pins from falling off or scratching the PCB board surface due to movement during operation, thereby reducing the scrap rate caused by physical damage.

[0014] 2. By setting several sets of magnetic blocks at the bottom, the nail bed board and the printing bed can be quickly fixed and the connection can be kept stable. The magnetic attraction does not require an additional fixing device, which can realize the quick installation and disassembly of the nail bed, greatly improving production efficiency and reducing equipment adjustment and replacement time.

[0022] 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.

[0023] Example 1

[0024] Please see Figures 1 to 5 As shown, the fast and simple solder resist screen printing nail bed device provided by this utility model includes a nail bed plate 1. The nail bed plate 1 has three sets of sliding grooves inside, and the three sets of sliding grooves are arranged in a linear array inside the nail bed plate 1. Several sets of PIN pins 2 are slidably sleeved inside the sliding grooves. The bottom end of each PIN pin 2 is fixedly connected to a nail seat 3. Several sets of square grooves are evenly opened at the bottom end of the sliding grooves. Limiting blocks 5 are set inside the square grooves. The bottom end of the limiting block 5 is fixedly connected to a connecting block 6. The bottom end of the connecting block 6 is fixedly connected to an adjusting block 7.

[0025] The nail bed board 1 has several sets of square grooves inside, and the size of the square grooves is fitted into the outer wall of the nail seat 3, and the square grooves are connected to the sliding grooves.

[0026] In use, place the corresponding number of PINs 2 and PIN holders 3 in each set of slides as needed. Align the PIN holders 3 with the slides and pull the PINs 2 to slide inside the PIN holders 3. When each set of PINs 2 and PIN holders 3 moves to the appropriate position, align the PIN holders 3 with the square slots and press down on the PINs 2 and PIN holders 3 so that the outer wall of the PIN holders 3 fits into the square slots, and the PIN holders 3 fits into the limiting block 5 to fix the position of the PIN holders 3.

[0027] Example 2

[0028] Based on Example 1, please refer to Figures 1 to 3 As shown, the nail holder 3 has a slot inside, and the bottom end of the slot is fitted with the outer wall of the limiting block 5. The top end of the slot is circular, and the diameter of the circle is slightly larger than the length of the limiting block 5.

[0029] The bottom end of the nail bed board 1 has several sets of round holes, and each round hole has an adjusting block 7 that is movably fitted inside. The adjusting block 7 is cuboid and has a long groove inside.

[0030] Once the PIN holder 3 is fixed, it engages with the limiting block 5. Then, by rotating the adjusting block 7, the top of the adjusting block 7 drives the limiting block 5 to rotate inside the PIN holder 3 via the connecting block 6. This causes the limiting block 5 to rotate from a vertical to a horizontal position inside the PIN holder 3, locking the PIN holder 3. This further prevents the PIN 2 and PIN holder 3 from becoming loose during use, which could affect the subsequent welding quality and reliability.

[0031] Example 3

[0033] By setting several sets of magnetic blocks 4 at the bottom, the nail bed board 1 is fixed to the printing bed by magnetic force, ensuring the stability and rapid positioning of the nail bed.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
