Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a PCB board production equipment. Background Technology

[0002] PCB manufacturing equipment is the key equipment in PCB production, enabling the accurate printing of electronic component connection circuits according to design requirements. During PCB processing, developing is a crucial step. The PCB is sealed with film to conceal areas that do not require etching. After exposure, it is placed in a developing bath where the developing solution cleans it, causing the ink in the etched areas to fall off, thus obtaining a transparent PCB.

[0003] Chinese Patent No. CN221043406U discloses a PCB production equipment, relating to the field of circuit board processing. This PCB production equipment, through the setting of a storage box, centrally stores cleaned PCBs. An air blowing component is used to blow air onto the PCBs placed in the storage box to remove residual water droplets from the boards, facilitating subsequent processing operations and making it more convenient to use. Furthermore, with the assistance of the air blowing component, the removed liquid is guided into a cleaning tank, saving production costs and avoiding waste of developing solution.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: after multiple PCB boards are cleaned in the developing solution in the cleaning tank, they need to be removed one by one and placed in the storage box before a new batch of PCB boards can be placed on the hook to continue the new round of cleaning work. The continuity of work is not high, the processing time is extended, and the processing efficiency is reduced. Utility Model Content

[0015] Example 1 like Figures 1 to 3 As shown, the PCB board production equipment proposed in this utility model includes a draining tank 1, a cleaning tank 102, a drive mechanism, and a material feeding mechanism. The bottom of the draining tank 1 is inclined, and a guide pipe 101 is installed at the drain end of the draining tank 1. A drying component 2 is provided on the inner wall of the draining tank 1. The upper end of the side wall of the cleaning tank 102 is connected to the output end of the guide pipe 101. The drive mechanism is located between the draining tank 1 and the cleaning tank 102. Two sets of material feeding mechanisms are provided, and both sets of material feeding mechanisms are installed at the output end of the drive mechanism. The two sets of material feeding mechanisms are driven by the drive mechanism to switch and adjust between the draining tank 1 and the cleaning tank 102 to clean or dry the PCB board body 10.

[0016] The material placement mechanism includes a base 401, a fixed clamping seat 5, and a movable clamping seat 6; the base 401 is connected to the lifting component 302; the fixed clamping seat 5 is installed on one side of the top of the base 401; a threaded rod 601 is rotatably connected to the movable clamping seat 6, the other end of the threaded rod 601 is threaded to the side end of the base 401, and the bottom end of the movable clamping seat 6 is slidably connected to the bottom end of the base 401. The fixed clamping seat 5 and the movable clamping seat 6 have the same structure, and both the fixed clamping seat 5 and the movable clamping seat 6 are provided with multiple sets of placement slots 8. The PCB board body 10 is inserted between two corresponding sets of placement slots 8 on the fixed clamping seat 5 and the movable clamping seat 6.

[0017] Furthermore, the drying assembly 2 consists of a loop pipe installed on the inner wall of the draining tank 1, multiple sets of air outlet pipes evenly inclined on the loop pipe, and a connecting valve installed at the input end of the loop pipe. The input end of the connecting valve extends to the outside of the draining tank 1 and is connected to an external hot air supply mechanism. By starting the hot air supply mechanism through the controller, hot air at a suitable temperature can be delivered into the loop pipe through the cleaning box 102. The hot air is blown along the air outlet pipe toward the PCB board body 10 on the material placement mechanism, accelerating the drying of the developing solution on the PCB board body 10 and improving processing efficiency.

[0018] Furthermore, the drive mechanism includes a mounting box 3, an electric rotating frame 301, and a lifting component 302. The mounting box 3 is installed between the drain tank 1 and the guide pipe 101, and a rotating component is installed inside the mounting box 3. The electric rotating frame 301 is T-shaped and is driven to rotate and connect to the mounting box 3 through the rotating component. The rotating component is composed of a gear transmission assembly and a motor that drives it to rotate, or the rotating component is composed of a synchronous belt assembly and a motor that drives it to rotate. A reducer is provided between the motor and the gear transmission assembly or the synchronous belt transmission assembly. Two sets of lifting components 302 are provided, and the two sets of lifting components 302 are symmetrically installed on the top of the electric rotating frame 301. The lifting component 302 is a hydraulic rod, and the output end of the lifting component 302 is connected to the material placement mechanism.

[0019] Furthermore, the base 401 is L-shaped, and a connecting frame 4 is installed on the higher end of the base 401. The connecting frame 4 is connected to the lifting component 302.

[0020] Furthermore, multiple sets of through holes 7 are evenly provided on the fixed clamping seat 5, the movable clamping seat 6, and the base 401, so as to facilitate full contact between the developing solution in the cleaning box 102 and the PCB board body 10, and at the same time, to facilitate full contact between the hot air blown out by the drying component 2 in the draining box 1 and the PCB board body 10, thereby improving processing efficiency.

[0021] In this embodiment, the controller starts the rotating component to drive the electric rotating frame 301 to rotate along the mounting box 3 at a suitable angle, so that the two sets of material placement mechanisms are respectively located above the drain box 1 and the cleaning box 102. The threaded rod 601 is rotated so that the movable clamping seat 6 slides along the bottom end of the base 401 towards the fixed clamping seat 5 at a suitable distance. Multiple sets of PCB board bodies 10 are respectively inserted between the two sets of placement slots 8 corresponding to the fixed clamping seat 5 and the movable clamping seat 6. The threaded rod 601 is adjusted until the movable clamping seat 6 and the fixed clamping seat 5 clamp the PCB board body 10. After multiple PCB board bodies 10 are placed in fixed positions on the feeding mechanism, one of the lifting components 302 is activated to move the feeding mechanism down to a suitable depth inside the cleaning tank 102, so that the PCB board body 10 is in full contact with the developing solution in the cleaning tank 102. The lifting component 302 can also move up and down through the output end, thereby moving the feeding mechanism up and down in the developing solution, which agitates the developing solution and ensures full contact between the developing solution and the PCB board body 10, improving the cleaning efficiency of the PCB board body 10. After cleaning, the driving mechanism is activated to switch the positions of the two feeding mechanisms, so that the PCB board body 10 in the other feeding mechanism enters the cleaning tank 102 for cleaning, while the cleaning feeding mechanism enters the draining tank 1 to drain the developing solution. The developing solution flows back to the cleaning tank 102 along the guide pipe 101 for reuse. The drying component 2 can dry the multiple PCB board bodies 10 in the feeding mechanism evenly and quickly. The cleaning and drying work of the two feeding mechanisms is carried out simultaneously without interference, improving processing efficiency.

[0022] Example 2 like Figures 2 to 4As shown, the PCB board production equipment proposed in this utility model, compared with Embodiment 1, includes a stabilizing component in the material placement mechanism. The stabilizing component is disposed on the fixed clamping seat 5 or the movable clamping seat 6. The PCB board body 10 is limited by the stabilizing component and the fixed clamping seat 5 and the movable clamping seat 6. The stabilizing component includes a slide rod 9, an adjusting rod 901, and an elastic element 902. Two sets of slide rods 9 are provided, and the two sets of slide rods 9 are symmetrically slidably connected to the fixed clamping seat 5 or the movable clamping seat 6. The length of the slide rod 9 is greater than the length of the fixed clamping seat 5 or the movable clamping seat 6. The slide rod 9 slides through each set of placement slots 8. Multiple sets of abutment plates 903 are evenly installed. One end of the abutment plate 903 is slidably connected to the side wall of the placement groove 8. Limit blocks are provided at both ends of the slide rod 9 to prevent the slide rod 9 from falling off the fixed clamping seat 5 or the movable clamping seat 6 during the adjustment process. The adjusting rod 901 is installed between one end of the two sets of slide rods 9 and abuts against the side wall of one end of the movable clamping seat 6 or the fixed clamping seat 5. One end of the elastic element 902 is connected to the other end of the slide rod 9, and the other end of the elastic element 902 is connected to the side wall of the other end of the fixed clamping seat 5 or the movable clamping seat 6. The elastic element 902 is a spring and is sleeved on the outside of the slide rod 9.

[0023] In this embodiment, the hand-held adjustment rod 901 drives the two sets of sliding rods 9 to slide along the fixed clamping seat 5 or the movable clamping seat 6, so that the abutment plate 903 slides inside the placement groove 8, causing the elastic element 902 to be compressed, and the PCB board body 10 is inserted between the abutment plate 903 and one side wall of the placement groove 8. Then, the tension on the adjustment rod 901 is released, and under the elastic force recovery of the elastic element 902, the sliding rod 9 slides along the placement groove 8, and then the edge of the PCB board body 10 is pressed into the placement groove 8 by the abutment plate 903, which further improves the installation stability of the PCB board body 10 and avoids it from falling off and being damaged during cleaning in the developer solution.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
