Description

Technical Field

[0001] This utility model belongs to the field of printed circuit board technology, specifically relating to a horizontal copper block browning machine. Background Technology

[0002] In the printed circuit board (PCB) industry, embedding high thermal conductivity copper blocks is a common method for achieving heat dissipation in high-power PCBs. Before embedding the copper block into the PCB and laminating it, its contact surface needs to be roughened; browning is a commonly used method in the industry. Horizontal browning lines are popular among PCB manufacturers due to their high efficiency. However, because the drive roller spacing of horizontal browning lines is relatively large, while the embedded copper blocks used in PCBs are small, direct horizontal browning is not possible. Therefore, existing methods have the following shortcomings when mass-producing PCBs with embedded copper blocks:

[0003] (1) When using a carrier plate fixture to attach copper blocks for browning, a lot of manpower is required. The copper blocks need to be removed and placed on a carrier plate, and they need to be removed again after browning is completed. Some processes also involve applying tape, which greatly consumes manpower.

[0004] (2) If the tray operation is not used, the browning line cannot be used directly for browning. The method of immersing the basket into the browning tank will face the problem of drying difficulties. Moreover, the cleaning and chemical treatment time during the process depends entirely on manual operation, making it difficult to ensure the consistency of quality.

[0005] (3) Using a carrier plate to brown copper blocks will occupy the production capacity of the browning line, and the circuit board cannot be browned when browning copper blocks; therefore, a horizontal line copper block browning machine is designed to change the above technical defects. Utility Model Content

[0006] (1) Technical problems to be solved

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a horizontal copper block browning machine to solve the above-mentioned technical problems.

[0008] (2) Technical solution

[0009] To solve the above-mentioned technical problems, this utility model provides a horizontal copper block browning machine, including a browning line body. The browning line body includes a feeding section, a washing section, a browning section, and a drying section arranged in sequence. Each feeding section, washing section, browning section, and drying section has a tank on one side. Each tank has a spray pump inside. Each tank has the same conveying mechanism above it. The tank above the feeding section has a feeding mechanism inside it. Each tank has an overflow port at the bottom. The bottom end of the overflow port is fixedly connected to a connecting pipe. Multiple branch pipes distributed vertically are fixedly connected to the side walls of the corresponding tanks on the washing section and browning section. One end of the branch pipe is fixedly connected to the water outlet of the spray pump, and the other end of the branch pipe is fixedly connected to a nozzle corresponding to the Teflon mesh belt.

[0010] Preferably, the conveying mechanism includes two rows of conveying wheels, each row of conveying wheels is wrapped with a Teflon mesh belt, and each row of conveying wheels includes multiple rollers distributed at intervals. One end of the Teflon mesh belt is provided with a feeding end, which is located on one side of the feeding mechanism, and the other end of the Teflon mesh belt is provided with a discharging end, which extends out of the outside of the tank on one side of the drying section.

[0011] Furthermore, the feeding mechanism includes a movable guide rail, which is fixedly installed at the top of the trough on one side of the feeding section. A movable suction cup mechanism is slidably fitted at the bottom of the movable guide rail. An aligning mechanism is fixedly installed below the movable suction cup mechanism and at the bottom of the corresponding trough. A carrier plate is installed at the top of the aligning mechanism.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. Low equipment cost: The main body utilizes the pumps and chemicals of the browning line, and a special tank for copper block treatment is set up on the side of the line. The pumps, chemicals, and water supply and drainage of the tank can share the adjacent browning line. The pump is equipped with an overflow port and connecting pipe to introduce new tanks. Usually, the amount of copper block browning is very small. This sharing method can reduce the cost of new equipment without affecting the normal operation of the browning main line.

[0018] 2. It greatly reduces manpower. By adopting an alignment mechanism and a moving suction cup mechanism, it achieves orderly loading and unloading of disordered copper blocks, which greatly reduces manpower input and eliminates the need for tape.

[0019] 3. The copper block browning effect is good. The horizontal browning method is highly efficient. Teflon mesh belts are wrapped around the upper and lower rollers of the original horizontal structure to hold the copper block in the middle of the Teflon mesh belt, ensuring that the copper block will not fall off and is less affected by the impact of water flow.

[0025] This specific embodiment is a horizontal copper block browning machine, the structural schematic diagram of which is shown below. Figures 1-4 As shown, the browning line body includes a feeding section 1, a washing section 2, a browning section 3, and a drying section 4 arranged in sequence. Each of the feeding section 1, washing section 2, browning section 3, and drying section 4 has a tank on one side. Each tank has a spray pump inside and the same conveying mechanism 5 is located above each tank. The feeding mechanism is located inside the tank above the feeding section 1. Each tank has an overflow port 7 at the bottom. The bottom end of the overflow port 7 is fixedly connected to a connecting pipe 8. The other end of the connecting pipe 8 extends into the adjacent corresponding tank. Multiple branch pipes 9 are fixedly connected to the side walls of the corresponding tanks on the washing section 2 and the browning section 3. One end of the branch pipe 9 is fixedly connected to the water outlet of the spray pump, and the other end of the branch pipe 9 is fixedly connected to a nozzle 10 corresponding to the Teflon mesh belt 502.

[0026] This equipment is low-cost. The main body utilizes the pumps and chemicals of the browning line, and a special tank for copper block processing is set up on the side of the line. The pumps, chemicals, and water supply and drainage of the tank can share the adjacent browning line. The overflow port 7 and connecting pipe 8 of the pump flow into the adjacent corresponding tank. Usually, the amount of copper block browning is very small. This sharing method can reduce the cost of new equipment without affecting the normal operation of the browning main line. The feeding mechanism can greatly reduce manpower and improve work efficiency.

[0027] The conveying mechanism 5 includes two rows of upper and lower conveying wheels. Each row of conveying wheels is wrapped with a Teflon mesh belt 502. Each row of conveying wheels includes multiple rollers 501 distributed at intervals. One end of the Teflon mesh belt 502 is provided with a feeding end 6, which is located on one side of the feeding mechanism. The other end of the Teflon mesh belt 502 is provided with a discharging end 601, which extends out of the outside of the tank on one side of the drying section 4. By adopting a horizontal browning method, the copper block browning effect is good and the efficiency is high. Teflon mesh belts 502 are wrapped around the outside of the upper and lower rollers 501 of the original horizontal structure, clamping the copper block in the middle of the Teflon mesh belt 502, ensuring that the copper block will not fall off and is less affected by the displacement caused by water flow.

[0028] In addition, the feeding mechanism includes a moving guide rail 101, which is fixedly installed at the top of the trough on one side of the feeding section 1. A moving suction cup mechanism 102 is slidably fitted at the bottom of the moving guide rail 101. An aligning mechanism 103 is fixedly installed below the moving suction cup mechanism 102 and at the bottom of the corresponding trough. A carrier plate 104 is installed at the top of the aligning mechanism 103. The moving suction cup mechanism 102 can move on the moving guide rail 101, so that the copper blocks picked up by the moving suction cup mechanism 102 are transported to the feeding end 6. At the same time, the aligning mechanism 103 uses the vibration and tilt of the XY axis to arrange the copper blocks neatly. The aligning mechanism 103 is similar to the equipment of the irregular metal sheet aligning machine, which greatly reduces manpower. By adopting the automatic aligning mechanism 103 and the moving suction cup mechanism 102, the orderly loading and unloading of disordered copper blocks is realized, which greatly reduces the manpower input and eliminates the need for tape.

[0029] In addition, the aligning mechanism 103 is located on the right side of the feed end 6. The middle part of the carrier plate 104 is provided with a plurality of grooves 105 arranged in an array. The middle part of the carrier plate 104 is provided with a plurality of through holes 106. The moving suction cup mechanism 102 is a multi-hole vacuum suction cup. The through holes 106 are located in the non-groove 105 area on the carrier plate 104. The moving suction cup mechanism 102 is a multi-hole vacuum suction cup with a full-surface opening, which can pick up the arranged copper blocks from the grooves 105 on the carrier plate 104. At the same time, due to the presence of the through holes 106, the carrier plate 104 will not be picked up.

[0030] In addition, a dryer is installed inside the drying section 4. Air knives 11 are installed in the corresponding tank of the drying section 4 and on the upper and lower sides of the Teflon mesh belt 502. The air inlet of the air knife 11 is connected to the dryer through an air pipe. Under the action of the air knife 11, the copper block after browning and water washing can be dried quickly.

[0031] Working principle: First, according to the different specifications of the copper blocks, carrier plates 104 with grooves 105 of different sizes are processed and placed in the alignment machine of the alignment mechanism 103 (not shown in the drawing), and the carrier plates 104 are fixed to the alignment machine with screws; then the copper blocks to be processed are placed in the material tray of the alignment machine; then the alignment machine is started by the external controller, and the alignment machine arranges the disordered copper blocks into an orderly arrangement, and then they are picked up by the moving multi-hole suction cup and placed into the feeding end 6; then the copper blocks pass through the water washing section 2 for acid and alkali washing and water washing, the browning section 3 for browning, water washing, and the drying section 4 for drying to reach the discharge section; finally, the browned copper blocks are loaded into the material frame.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
