Therefore, during the dip coating process of the circuit board body, avoid frequent shaking of the hanging basket, which may cause leakage of the dipping liquid, reduce the waste of the dipping liquid, and reduce the shaking frequency of the hanging basket, thereby reducing the wear of the corresponding parts, extending the service life of the equipment, and reducing the production cost expenditure of the enterprise.

[0030] It also includes a circulation pump 102, a conduit I 103 and a conduit II 104; a reflux chamber 10101 is opened in the limiting plate 101; a plurality of reflux holes 10102 are equidistantly opened on the inclined surface of the limiting plate 101; the reflux chamber 10101 is connected with the corresponding reflux holes 10102; a circulation pump 102 is installed outside the dipping box 2; the water inlet end of the circulation pump 102 is connected with the conduit I 103; the water outlet end of the circulation pump 102 is connected with the conduit II 104; the conduit I 103 is connected with the upper part of the dipping box 2; the conduit II 104 runs through the lower part of the dipping box 2 and the limiting plate 101, and the conduit II 104 is connected with the reflux chamber 10101.

[0031] The spacer bar 1101 is made of rubber material and is used to prevent the circuit board body 001 from being damaged when the circuit board body 001 collides with the spacer bar 1101 .

[0032] It also includes an electric guide rail 3 and an electric slider 4; the chassis 1 is equipped with two electric guide rails 3 distributed front and back; each electric guide rail 3 is slidably connected to an electric slider 4; the two electric sliders 4 are connected to the suspension beam 6 together.

[0034] The working steps of the above embodiment are:

[0035] First, before using the equipment, pour an appropriate amount of coating liquid into the coating box 2 to prevent corrosion of exposed copper on the circuit board body 001. The amount of coating liquid injected is to fill the hanging basket 11 with the circuit board body 001 and immerse it in the coating liquid. The coating liquid can cover the top of the hanging basket 11 and the coating liquid will not overflow from the coating box 2. Then control the external conveyor belt to transport the processed circuit board body 001 to the vicinity of the equipment. Then the external manipulator clamps the circuit board body 001 in turn and transfers it to the hanging basket 11 of the equipment, so that each circuit board body 001 is located between adjacent rubber spacers 1101, until a circuit board body 001 is loaded between every two spacers 1101 in the hanging basket 11, and then control the electric slider 4 to move in the electric The movable guide rail 3 moves to the left, synchronously driving the electric actuator Ⅰ5 and the corresponding parts thereon to move, so that the hanging basket 11 moves to the left. When the hanging basket 11 reaches the vicinity of the dipping box 2, the two electric actuators Ⅰ5 are controlled to extend, and the suspension beam 6 and the corresponding parts thereon are synchronously driven to move upward, so that the position of the hanging basket 11 is higher than that of the dipping box 2. Then the hanging basket 11 is controlled to move above the dipping box 2, and the two electric actuators Ⅰ5 are contracted, synchronously driving the suspension beam 6 and the corresponding parts thereon to descend, so that the hanging basket 11 and the circuit board body 001 therein are slowly immersed in the dipping liquid, and then the left end of the bottom of the hanging basket 11 contacts the limit plate 101. At this time, the motor 7 is controlled to start. From the front to the back, the output shaft of the motor 7 rotates clockwise, and the output shaft of the motor 7 drives the transmission rod 8 and the corresponding parts thereon The parts rotate, causing the hanging basket 11 to tilt to the right, and at the same time, the two electric actuators Ⅰ5 are controlled to shrink until the bottom of the hanging basket 11 is completely attached to the inclined surface of the limit plate 101, and the motor 7 and the electric actuator Ⅰ5 are controlled to stop. At the same time, the circuit board body 001 is uniformly leaned against an adjacent partition 1101 on the right due to the tilted hanging basket 11, thereby achieving uniform positioning of the partition 1101, and then the circulation pump 102 is controlled to start. At this time, the liquid level in the dipping box 2 is higher than the position of the pipe mouth of the conduit Ⅰ103. The circulation pump 102 draws out the dipping liquid on the upper part of the dipping box 2 through the conduit Ⅰ103, and then pumps it into the reflux chamber 10101 through the conduit Ⅱ104, and then sprays it onto the circuit board body 001 of the hanging basket 11 through the reflux hole 10102, so as to By circulating the coating liquid, the coating liquid is brought into better contact with the circuit board body 001, and the coating is more evenly applied on the surface of the circuit board body 001, and by controlling the starting motor 7, when viewed from the front to the back, the output shaft of the motor 7 rotates counterclockwise, synchronously driving the transmission rod 8 and the corresponding parts thereon to rotate, so that the right part of the hanging basket 11 is lifted upward, and the circuit board body 001 does not exceed the liquid surface of the coating liquid, and synchronously driving the circuit board body 001 thereon to swing to the left in the coating liquid, thereby making the flow direction of the coating liquid sprayed from the reflux hole 10102 of the inclined surface not parallel to the surface of the circuit board body 001, and the coating liquid sprayed from the reflux hole 10102 will impact the surface of the circuit board body 001, and because the circuit board body 001 is placed in the coating liquid,There will still be some air remaining in the circuit diagram groove of the circuit board body 001, so that the dipping liquid cannot fully contact the copper at the circuit diagram groove of the circuit board body 001, resulting in poor dipping effect. Therefore, when the flow path of the dipping liquid sprayed from the reflux hole 10102 is not parallel to the surface of the circuit board body 001, the dipping liquid sprayed from the reflux hole 10102 will impact the circuit diagram groove on the surface of the circuit board body 001, thereby achieving impact on the bubbles trapped in the circuit diagram groove on the surface of the circuit board body 001, and then control the motor 7 to rotate clockwise to reset the hanging basket 11, and repeatedly swing the hanging basket 11 to discharge the flushed bubbles to the liquid surface, so that the surface of the circuit board body 001 is fully in contact with the dipping liquid, improving the coating quality and ensuring the integrity and uniformity of the coating.

[0036] After a certain period of dipping, ensure that the exposed copper of the circuit board body 001 is covered with the coating, then control the motor 7 to keep the hanging basket 11 horizontal, then control the two electric actuators Ⅰ5 to extend, synchronously drive the suspension beam 6 and the corresponding parts thereon to move upward, so that the hanging basket 11 is higher than the dipping box 2, control the electric actuator Ⅰ5 to stop, then control the start motor 7 to rotate forward and reverse periodically, synchronously drive the transmission rod 8 and the corresponding parts thereon to rotate forward and reverse, so that the hanging basket 11 and the circuit board body 001 therein swing left and right, thereby achieving the shaking off of the residual dipping liquid on the hanging basket 11, and at the same time, during the swinging process of the hanging basket 11, synchronously drive the circuit board body 001 therein to periodically stick to the adjacent partition bar 1101, and shake off the excess dipping liquid on the circuit board body 001 through the impact caused by the sticking. 101 is made of rubber, which effectively prevents the circuit board body 001 from being damaged when it hits the partition bar 1101. The shaken-off coating liquid falls back into the coating box 2, so that the coating liquid is recovered and the time for the hanging basket 11 and the circuit board body 001 therein to wait for the coating liquid to flow back is effectively reduced, thereby improving the processing efficiency of the circuit board body 001 and the production efficiency of the enterprise. When the hanging basket 11 and the circuit board body 001 therein no longer drip the coating liquid, the hanging basket 11 is restored to a horizontal state, and then the electric slider 4 is controlled to continue to move to the left. After the hanging basket 11 leaves the top of the coating box 2, the two electric actuators Ⅰ5 are controlled to contract, so that the hanging basket 11 descends, thereby lowering the center of gravity of the moving parts of the equipment, making the transportation of the circuit board body 001 safer and more stable.

[0037] Second embodiment

[0038] On the basis of the first embodiment, according to Figure 1 , Figure 2 and Figure 4-Figure 8As shown, it also includes a limit frame 201, an electric actuator II 202, a connecting rod 203, a special-shaped steel bar 204 and a contact rod 205; the middle part of the hanging basket 11 is connected to the limit frame 201; the lower part of the limit frame 201 is equipped with two electric actuators II 202 distributed on the left and right; the electric actuator II 202 is an electric push rod; the electric actuator II 202 has a waterproof effect; the telescopic parts of the two electric actuators II 202 are fixedly connected to the connecting rod 203; the connecting rod 203 is connected to a plurality of special-shaped steel bars 204 symmetrically arranged front and back; The special-shaped steel bar 204 is an arc-shaped memory metal spring sheet with a V-shaped cross section. The special-shaped steel bar 204 cannot be deformed when it is limited by the limit frame 201. The special-shaped steel bar 204 will produce elastic deformation when it loses the limit of the limit frame 201, and automatically curls up by utilizing the memory of the material. Its shape is equivalent to a "pop ring"; all the special-shaped steel bars 204 are slidingly connected to the limit frame 201; the front special-shaped steel bars 204 are connected to a contact rod 205; the rear special-shaped steel bars 204 are connected to another contact rod 205.

[0039] The contact rod 205 is configured to be semi-cylindrical, and a rubber gasket is disposed on the plane section of the contact rod 205 to increase the contact friction between the contact rod 205 and the circuit board body 001 .

[0040] It also includes an electric actuator III301; two electric actuators III301 distributed front and back are installed in the middle of the hanging basket 11; the electric actuator III301 is an electric push rod; the telescopic parts of the two electric actuators III301 are fixedly connected to the limit frame 201; the limit frame 201 is slidably connected to the hanging basket 11; the electric actuator III301 has a waterproof effect.

[0041] The working steps of the above embodiment are:

[0042] On the basis of the first embodiment, considering that after the hanging basket 11 has been immersed in the coating liquid, in order to improve the coating efficiency and the coating effect, it is necessary to make the hanging basket 11 swing frequently in the coating liquid, which may easily cause the coating liquid to splash out of the coating box 2, resulting in a waste of the coating liquid, and when the circuit board body 001 is placed in the coating liquid, the air in the circuit diagram groove on the circuit board body 001 is not discharged in time, so that there are bubbles in the circuit diagram groove on the circuit board body 001, resulting in insufficient contact between the coating liquid and the circuit board body 001. Therefore, after the hanging basket 11 is placed on the limit plate 101, the two electric actuators II 202 are controlled to contract, and the connecting rod 203 and the corresponding parts thereon are synchronously driven to move upward. The special-shaped steel bar 204 is an arc-shaped memory metal spring, and its cross-section is as shown in FIG. Figure 7As shown in the figure, it is V-shaped. When the special-shaped steel bar 204 passes through the upper part of the limit frame 201, the part of the special-shaped steel bar 204 that passes through loses the limit of the limit frame 201, so that the part of the special-shaped steel bar 204 that passes through the limit frame 201 bends in the direction away from the limit frame 201, and the special-shaped steel bar 204 drives the contact rod 205 to move, as shown in FIG. Figure 6 As shown, until the flat section of the contact rod 205 contacts the circuit board body 001 and applies downward pressure to the circuit board body 001, a rubber gasket is provided at the flat section of the contact rod 205, so that the contact friction between the contact rod 205 and the circuit board body 001 is increased, and then the two electric actuators III301 are controlled to extend, synchronously driving the limit frame 201 and the corresponding parts thereon to move to the left, so that the contact rod 205 drives the corresponding upper part of the circuit board body 001 to move, wherein since the hanging basket 11 is in an inclined state at this time, the bottom surface of the hanging basket 11 fits with the inclined surface of the limit plate 101, so that all the circuit board bodies 001 are leaning on the partition bar 1101 on the right side under the action of gravity, and the movement of the contact rod 205 only drives the upper end of the circuit board body 001 to move to the left, thereby realizing the swing of the circuit board body 001, thereby making the flow direction of the dipping liquid sprayed out of the reflux hole 10102 aligned with the circuit board body 00 1 is not parallel, so that the coating liquid impacts the surface of the circuit board body 001, so that the coating liquid is in full contact with the circuit board body 001, and the bubbles in the circuit board body 001 are discharged, and then the electric actuator III 301 is controlled to contract, and the upper end of the circuit board body 001 is synchronously swung to the right, and all the circuit board bodies 001 are re-attached to the partition bar 1101 on the right side, so that the impacted bubbles quickly float to the liquid surface of the coating liquid, and the bubbles are prevented from re-attaching to the circuit board body 001, affecting the uniformity of the coating and the coating effect. In this way, the frequent shaking of the hanging basket 11 in the first embodiment, which leads to the leakage of the coating liquid, reduces the waste of the coating liquid, and effectively reduces the frequency of pulling the cable 10, thereby reducing the wear of the corresponding components such as the transmission rod 8, the reel 9, the cable 10 and the hanging basket 11, prolonging the service life of the equipment and reducing the production cost expenditure of the enterprise.

Accordingly, the scope of the present invention should be limited only by the appended claims.
