Description

Technical Field

[0002] In the field of modern electronic manufacturing, circuit boards are the core components of electronic products, and their production quality is of vital importance. Electroplating technology is widely used in circuit board production, which can improve the conductivity, corrosion resistance and other properties of circuit boards. However, the current electroplating cleaning machines used in circuit board production have certain technical limitations.

[0003] On the one hand, existing electroplating cleaning machines often lack effective pre-dust removal functions. Before the circuit board enters the electroplating cleaning machine, some tiny particles such as dust and fiber may adhere to its surface.

[0019] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0020] like Figures 1 to 7As shown, an electroplating cleaning machine for circuit board production provided by an embodiment of the present invention comprises a cleaning pool 1, a fixing mechanism 3 is arranged in the middle of the upper end of the cleaning pool 1, a plurality of circuit board bodies 5 are arranged on the circumference of the fixing mechanism 3, blowing mechanisms 4 are arranged on both sides of the upper end of the cleaning pool 1, a spray mechanism 2 is connected to the bottom of the blowing mechanism 4, the spray mechanism 2 comprises a water pipe 22 and a liquid storage tank 28, the water pipe 22 is fixedly installed on the inner wall of the cleaning pool 1, one end of the water pipe 22 is fixedly connected to the water pump 21, a plurality of nozzles 23 are equidistantly arranged on the water pipe 22, a piston cylinder 24 is arranged on one side of the water pipe 22, and the liquid storage tank 28 is connected to one end of the piston cylinder 24 through a second connecting pipe 29.

[0021] Specifically, the fixing mechanism 3 is used to clamp and fix the circuit board body 5. Figure 5 The fixing mechanism 3 drives the circuit board body 5 to rotate in a counterclockwise direction, and stops after each rotation of 90 degrees. The blowing mechanism 4 on the left is used to pre-treat the circuit board body 5 and blow away the dust and impurities on the circuit board body 5. The pre-treated circuit board body 5 is driven to the middle of the cleaning tank 1 by the fixing mechanism 3, and is sprayed and cleaned by the spraying mechanism 2 to further wash away the dirt, oil stains on the surface of the circuit board body 5 and impurities such as the plating liquid remaining in the electroplating process. After the cleaning is completed, the circuit board body 5 is brought to the right side by the fixing mechanism 3, and the moisture on the surface of the circuit board body 5 is removed in time by the blowing mechanism 4 to keep the circuit board body 5 dry.

[0022] Furthermore, the fixing mechanism 3 includes a first motor 31 and a plurality of pneumatic clamping fingers 34. The first motor 31 is fixedly installed in the middle of the upper end of the cleaning tank 1. The output end of the first motor 31 is fixedly connected to a rotating shaft 32. A mounting seat 33 is fixedly sleeved on the middle shaft of the rotating shaft 32. A plurality of pneumatic clamping fingers 34 are fixedly installed in a circle on the side of the mounting seat 33. The plurality of pneumatic clamping fingers 34 are clamped at one end of the circuit board body 5.

[0023] Specifically, the pneumatic clamping fingers 34 are closed to clamp the circuit board body 5 to ensure that the circuit board body 5 will not loosen or fall off during operation. When the first motor 31 receives the control signal, the driving shaft 32 rotates at a certain speed and angle to pass the circuit board body 5 clamped on the pneumatic clamping fingers 34 through the blowing pretreatment station, the spray cleaning station and the blowing air drying station in sequence to complete the entire cleaning and drying process.

[0024] Furthermore, the blowing mechanism 4 includes a second motor 41 and an air pump 43, both of which are fixedly mounted on the outer side of the cleaning tank 1, and the output ends of the second motor 41 and the air pump 43 are respectively fixedly connected with a screw rod 42 and an air pipe 44, and the end of the screw rod 42 away from the second motor 41 is rotatably mounted on the inner side wall of the cleaning tank 1, and a movable block 410 is threadedly sleeved on the rod body of the screw rod 42, and a limit block 49 is fixedly connected to the upper surface of the movable block 410, and the limit block 49 is slidably connected to the inner side wall of the cleaning tank 1. At the top of one end of the cleaning pool 1, a bracket 48 is fixedly connected to the upper surface of the limit block 49, a dust cover 46 is fixedly connected to the top of the bracket 48, an air pipe 44 is fixedly installed on the dust cover 46, and a plurality of air nozzles 45 are equidistantly arranged on the air pipe 44, and the air outlets of the air nozzles 45 extend to the inside of the dust cover 46. A baffle 412 is rotatably connected to one side of the dust cover 46 through a torsion spring 413, and a filter box 47 is fixedly connected to one end of the dust cover 46, and a detachable filter net 411 is arranged in the filter box 47.

[0025] Specifically, the bottom of the dust cover 46 is fixed by a bracket 48 and a limit block 49, and the limit block 49 is slidably connected to the cleaning tank 1 to limit the dust cover 46. The air pipe 44 is fixed on the dust cover 46 in a U shape. The air pipe 44 can be provided with two groups, which are respectively located at the upper and lower parts of the dust cover 46, so as to ensure the cleaning and air-drying effects on both sides of the circuit board body 5. The air nozzle 45 is tilted on the air pipe 44, and a plurality of air nozzles 45 are distributed at one end away from the filter box 47. The air outlet of the air nozzle 45 at this end faces the direction of the filter box 47, and the air outlets of the air nozzles 45 on both sides face the direction close to each other. The baffle 412 is in a close contact with the bottom of the dust cover 46 in the initial state. During the movement of the dust cover 46, the baffle 412 flips over, and after being separated from the pneumatic clamping finger 34, it is reset under the action of the torsion spring 413.

[0026] When in use, the circuit board body 5 is brought to the air blowing pretreatment station through the fixing mechanism 3, and the screw rod 42 is driven to rotate by starting the second motor 41. The dust cover 46 moves in the direction close to the circuit board body 5 through the threaded cooperation between the screw rod 42 and the movable block 410 and the sliding cooperation between the limit block 49 and the cleaning tank 1. Then the torsion spring 413 contacts and flips one side of the pneumatic clamping finger 34. When the dust cover 46 moves into place, the torsion spring 413 is reset, and then the air pump 43 is started to allow air to enter the air pipe 44 and then blow it out from a plurality of air nozzles 45. The air nozzles 45 on both sides blow dust and impurities to the middle, and the air nozzle 45 at one end blows dust and impurities into the filter box 47, and adsorbs them through the filter screen 411 in the filter box 47. The filter screen 411 is subsequently disassembled and cleaned. Through this technical solution, dust and impurities on the surface of the circuit board body 5 can be removed in advance to prepare for subsequent spray cleaning and improve the spray cleaning effect.

[0027] The circuit board body 5 after spray cleaning is brought to the blowing and drying station through the fixing mechanism 3, and the cleaning liquid and water stains remaining on the surface of the circuit board body 5 are removed through the air nozzle 45 to prevent moisture from corroding and damaging the circuit board body 5. It should be noted that the blowing mechanism 4 can be equipped with an electric heating device to use hot air to accelerate the drying of the circuit board body 5.

[0028] In the present application, the blowing mechanisms 4 on both sides move synchronously, so that the circuit board bodies 5 at the three workstations can be in different working states at the same time, realizing automatic and continuous dust removal, cleaning and drying, and greatly improving production efficiency.

[0029] Furthermore, the water pump 21 and the liquid storage tank 28 are both fixedly installed on the outer surface of the cleaning pool 1, the piston cylinder 24 is fixedly installed on the side wall of one end of the cleaning pool 1, and a piston rod 26 is arranged inside the piston cylinder 24, one end of the piston rod 26 is fixedly connected to a connecting block 25, the upper end of the connecting block 25 is fixedly connected to a connecting frame 211, the top of the connecting frame 211 is fixedly connected to the movable block 410, the lower end of the connecting block 25 is slidably sleeved on the water pipe 22, one end of the water pipe 22 is connected to one end of the piston cylinder 24 through the first connecting pipe 27, a one-way valve 210 is installed on the second connecting pipe 29, and both ends of the second connecting pipe 29 are respectively fixedly connected to the liquid storage tank 28 and the piston cylinder 24.

[0030] Specifically, the liquid storage tank 28 is used to store cleaning liquid, the water pipe 22 is arranged in a U shape inside the cleaning pool 1, and a plurality of nozzles 23 are distributed obliquely in a row outside the circuit board body 5. This arrangement can spray and clean both sides of the circuit board body 5 at the same time.

[0031] When the piston rod 26 is located at one end of the piston cylinder 24, the cleaning water does not enter the piston cylinder 24. In this state, the three circuit board bodies 5 are in working state. When the working state of the circuit board body 5 needs to be replaced, the dust cover 46 drives the connecting block 25 to move, so that the piston rod 26 moves along the Figure 7 As shown in the figure, it moves to the right, causing a certain pressure difference in the piston cylinder 24. The pressure difference causes water and cleaning liquid to be sucked into the piston cylinder 24 from the first connecting tube 27 and the second connecting tube 29 respectively. On the one hand, the quantitative entry of the cleaning liquid is achieved. On the other hand, the water and the cleaning liquid are automatically mixed under the action of pressure to form a cleaning mixture. Thirdly, water enters the piston cylinder 24, which reduces the flow rate in the water pipe 22, thereby reducing the spray flow rate, which can reduce the use of water during the change of working state and avoid waste.

[0032] Working principle of the present invention: When in use, the circuit board body 5 is clamped by the pneumatic clamping fingers 34, the first motor 31 brings the circuit board body 5 to the pretreatment station, the second motor 41 is started to drive the dust cover 46 to move, so that the dust cover 46 covers the circuit board body 5, the air pump 43 is started to blow air, and the dust and impurities on the surface of the circuit board body 5 are blown into the filter box 47, and then the dust cover 46 is reset. During the resetting process, the piston rod 26 is driven to move, so that a certain pressure difference is generated in the piston cylinder 24. The pressure difference causes water and cleaning liquid to be sucked into the piston cylinder 24 from the first connecting pipe 27 and the second connecting pipe 29 respectively, so as to achieve The quantitative entry of the cleaning liquid and its automatic mixing with water can reduce the spray flow rate and reduce the water consumption during the transposition process. After the transposition is completed, the dust cover 46 moves in the opposite direction and is placed on the next circuit board body 5 to be processed, while driving the piston rod 26 to move in the opposite direction to send out the cleaning mixture, so that the spray flow rate is restored, and the dirt and impurities such as the electroplating liquid on the surface of the circuit board body 5 are removed by the cleaning mixture. After the cleaning is completed, the circuit board body 5 is brought to the air blowing and drying station, and the residual moisture on the surface of the circuit board body 5 is removed by the air nozzle 45. After the work is completed, the circuit board body 5 is removed.

[0033] In summary: this electroplating cleaning machine for circuit board production clamps the circuit board body 5 through the fixing mechanism 3, sprays and cleans the circuit board body 5 through the spray mechanism 2, removes dust and air-dries the circuit board body 5 through the blowing mechanism 4, and realizes different working states of blowing pretreatment, spray cleaning and blowing air drying by adjusting the working position of the circuit board body 5, thereby completing the entire processing process, and can also make the circuit board body 5 at three workstations in different working states at the same time, realizing automatic continuous dust removal, cleaning and drying, and greatly improving production efficiency.
