Description

Technical Field

[0001] The invention relates to the technical field of PCB board production equipment, and in particular to a galvanizing auxiliary device for PCB board welding. Background Art

[0002] PCB boards are usually made of insulating materials, such as glass fiber and epoxy resin, and the surface of the PCB board needs to be coated with conductive materials to form a circuit pattern. In addition, the design and manufacturing process of the PCB board is very precise, involving circuit design, wiring, printing, and assembly process steps. The PCB board accurately controls signal and power transmission through circuit design, avoiding electromagnetic interference and loose connection problems that may be encountered when using traditional wiring harnesses. At the same time, the PCB board can be designed into a very compact form as needed, saving equipment space and reducing overall weight. When the PCB board is produced, the PCB board pad needs to be galvanized to ensure the welding quality of the PCB board and protect the corrosion resistance of the circuit board pad;

[0003] However, the prior art still has the following defects when used specifically:

[0004] During the galvanizing process, the PCB pad surface needs to be kept clean. Dust on the PCB pad surface will lead to poor welding. For example, bubbles, oxides or contaminants will appear during welding, resulting in loose solder joints and even welding failure. The prior art uses compressed air to blow the PCB surface to physically blow away the dust and small particles on the surface. This method is often used in the pretreatment step before cleaning. Although it reduces the workload of chemical cleaning, the dust blown up is easy to float around, thereby reducing the cleaning effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention;

[0029] Embodiments of the present invention

[0030] Please refer to Figures 1 to 5 As shown, a galvanizing auxiliary device for PCB board welding includes a workbench 1, a support base 2 is fixedly connected to the middle of the top of the workbench 1, a rectangular vertical plate 3 is arranged above the top of the workbench 1, a semi-enclosed cover plate 301 is fixedly connected to the outer wall of the rectangular vertical plate 3 located on one side of the support base 2, the semi-enclosed cover plate 301 is slidably matched with the support base 2, a galvanizing equipment body 302 is fixedly connected to the inner wall of the top of the semi-enclosed cover plate 301, and an auxiliary cleaning mechanism is arranged inside the semi-enclosed cover plate 301 and located on one side of the galvanizing equipment body 302;

[0031] The auxiliary cleaning mechanism includes a hollow cylinder 401 rotatably connected to the inner wall of the semi-enclosed cover plate 301, and the outer wall of the hollow cylinder 401 is evenly provided with a plurality of through holes 402 in an annular distribution, and the outer wall of the hollow cylinder 401 is evenly fixedly connected with a plurality of cleaning strips 403, and the plurality of cleaning strips 403 are all designed to be movable and detachable, and the outer wall of the end of the hollow cylinder 401 is rotatably connected with a sealing end cap 404, and the side wall of the sealing end cap 404 is fixedly connected with a cross bar 407 located on one side of the outer wall of the hollow cylinder 401, and the sealing end cap 404 is connected with the inside of the hollow cylinder 401, and the sealing The top of the end cover 404 is fixedly connected with a sealing tube 405, which is communicated with the inside of the sealing end cover 404. The top of the sealing tube 405 passes through the inner wall of the top of the semi-enclosed cover plate 301 and is fixedly connected with a dust collector 406. The dust collector 406 is fixedly connected to the top of the semi-enclosed cover plate 301, and the sealing tube 405 is also communicated with the dust collector 406. The outer wall of the end of the hollow cylinder 401 and located on one side of the sealing end cover 404 is also fixedly connected with a rotating wheel 501. The manufacturing material of the rotating wheel 501 is rubber, and the outer wall of the rotating wheel 501 is evenly provided with a plurality of anti-slip lines;

[0032] Among them, by pushing the rectangular vertical plate 3 toward one side of the support base 2, the semi-enclosed cover plate 301 gradually slides on the outer wall of the top of the support base 2, and before the hollow cylinder 401 does not contact the PCB pad, the vacuum cleaner 406 is started, so that the vacuum cleaner 406 cooperates with the sealing tube 405 to suck in the dust and other impurities that the hollow cylinder 401 contacts through the through hole 402, which is convenient for subsequent unified collection. As the hollow cylinder 401 moves on the surface of the PCB pad, the dust and other impurities on the surface of the PCB pad can be cleaned. The adsorption work is performed, and when the rotating wheel 501 contacts the top of the supporting base 2, the rotating wheel 501 can roll on the surface of the supporting base 2 under the action of friction. As the rotating wheel 501 continues to roll, the hollow cylinder 401 can make a circular motion with the cleaning strip 403. In addition, since the hollow cylinder 401 and the sealing end cover 404 rotate in coordination, the sealing tube 405 can always remain in an upright state during the rotation of the hollow cylinder 401, and the cleaning strip 403 is used to cyclically contact the surface of the PCB pad, so that the PCB can be fully cleaned. The dust on the surface of the CB board pad is cleaned, and the cleaned dust is adsorbed by the through hole 402, so as to avoid the dust from spreading and causing pollution in a wider range. At the same time, the rotating cleaning bar 403 can avoid the same cleaning bar 403 from repeatedly contacting the PCB board welding disk, which is beneficial to improving the service life of the cleaning bar 403. At the same time, after the cross bar 407 contacts the cleaning bar 403, the cleaning bar 403 will shake, so that the cleaning bar 403 will shake off the floating dust adhering to itself, ensuring the cleanliness of the cleaning bar 403 body. In addition, the cleaning bar 403 is designed to be movable and detachable, and can be replaced after a period of use, ensuring that the cleaning bar 403 can have a good cleaning effect. After cleaning, as the semi-enclosed cover plate 301 continues to move on the surface of the supporting base 2, the galvanizing equipment body 302 can be evenly galvanized on the surface of the cleaned PCB board pad. By cleaning the surface of the PCB board pad, the solder adhesion can be improved, and the situation of easy peeling or formation of bad points can be avoided, which helps to improve the stability of the overall welding connection;

[0033] Please refer to Figure 1 , Figure 2 As shown, as a preferred embodiment, two long guide rails 601 are fixedly connected on the top of the workbench 1 and are symmetrically fixedly connected with the semi-enclosed cover plate 301 as the center axis, and the outer walls of the top ends of the two long guide rails 601 are slidably connected with a sliding seat 602, and the top of the sliding seat 602 is fixedly connected to the bottom of the rectangular vertical plate 3, and a mounting frame 603 is fixedly connected to the top of the workbench 1 and away from the semi-enclosed cover plate 301. An electric push rod 604 is inserted into the top of the mounting frame 603, and the extended end of the electric push rod 604 is fixedly connected to the outer wall of the rectangular vertical plate 3;

[0034] When the PCB pads are fixed, the staff starts the electric push rod 604 through the control panel, so that the extended end of the electric push rod 604 pushes the rectangular vertical plate 3 forward. Since the bottom of the rectangular vertical plate 3 is fixedly connected with the sliding seat 602, and the sliding seat 602 slides on the outer wall of the long guide rail 601, the rectangular vertical plate 3 can be stable during the movement.

[0035] Please refer to Figures 6 to 8 As shown, as a preferred embodiment, an auxiliary fixing mechanism is provided inside the support base 2;

[0036] The auxiliary fixing mechanism includes a rectangular groove 701 opened on the inner wall of the top of the support base 2, the inner wall of the top of the rectangular groove 701 is fixedly connected to the support frame 702, and two C-shaped plates 703 are symmetrically arranged on the inner wall of the top of the rectangular groove 701 and located above the support frame 702, and the two C-shaped plates 703 are fixedly connected with long air bag strips 704 inside, and the outline shape of the long air bag strips 704 is convex upward and concave downward. A four-legged pressure block 705 is slidably connected to the inner wall of the support frame 702, and a sealing bag 706 is fixedly connected to the inner wall of the bottom of the rectangular groove 701 and located below the four-legged pressure block 705. An air delivery conduit 707 is fixedly connected between the sealing bag 706 and the two long air bag strips 704, and the air delivery conduit 707 is connected to the sealing bag 706 and the inside of the air delivery conduit 707;

[0037] Among them, through the downward pressure of gravity, the four-legged pressing block 705, which is pressed by the PCB pad, will slide downward on the inner wall of the support frame 702. During the descending process, the upper end and the lower end frame of the PCB pad will contact the long airbag strip 704. Since the contour of the long airbag strip 704 is convex and concave, under the extrusion, the long airbag strip 704 is deformed to the side of the C-shaped plate 703, and the PCB pad passes smoothly. Then, the protruding part of the long airbag strip 704 is reset under the elastic action and covers the top of the PCB pad frame. As the four-legged pressing block 705 descends in height, it continues to press the sealing bag 706, causing the sealing bag 706 to be squeezed and deformed, and the air generated in the cavity opened inside is discharged into the long airbag strip 704 through the air supply duct 707. With the input of air, the long airbag strip 704 gradually changes from an unsaturated state to an expanded state. When P When the CB board pad finally falls on the surface of the support frame 702, the expanded long air bag strip 704 cooperates with the support frame 702 to press and fix the PCB board pad. Then the staff rotates the fixing buckle 801 so that the fixing buckles 801 on both sides can rotate ninety degrees, and finally the tip of the fixing buckle 801 falls on the surface of the PCB board pad, which plays a role of longitudinal limit to prevent it from moving up and down. At the same time, the long air bag strip 704 and the support frame 702 can be used to firmly fix the PCB board pad inside the support base 2, which plays a role of lateral limit to prevent it from moving around, which is convenient for subsequent operations. Compared with the problem that the clamp used in the prior art needs a power source during operation, this equipment is convenient for personnel to operate, saves energy, reduces the failure rate, and thus increases the use efficiency of the equipment, so that the reliability is improved;

[0038] Please refer to Figure 6 , Figure 8 As shown, as a preferred embodiment, the sealing bag 706 is made of soft rubber, a cavity is provided inside the sealing bag 706, two fixed buckles 801 are symmetrically rotatably connected to the top of the support base 2 and located between the two C-shaped plates 703, and the contours of the two fixed buckles 801 are both pointer-shaped, and two short guide rails 901 are symmetrically fixedly connected to the top of the workbench 1 and located at both ends of the two fixed buckles 801, and the outer walls of the two short guide rails 901 are slidably connected to sliding blocks 902, and the bottoms of the ends of the two sliding blocks 902 away from the short guide rails 901 are fixedly connected to the top of the C-shaped plate 703, and the inner walls of the two sliding blocks 902 are threadedly connected to bolts 903;

[0039] Among them, the bolt 903 is loosened so that the sliding block 902 can slide on the outer wall of the short guide rail 901 with the C-shaped plate 703. After the C-shaped plate 703 is adjusted into place, the bolts 903 are tightened in sequence, so that the sliding block 902 and the C-shaped plate 703 can be firmly fixed. By adjusting the size between the two C-shaped plates 703, the support base 2 can meet the needs of fixing PCB board pads of different widths, which greatly improves the utilization efficiency of the equipment. The fixing buckle 801 has a certain length, so that the rotating fixing buckle 801 can press and fix the two side frames of PCB board pads of different lengths, which further improves the practicality.

[0040] The following are the complete usage steps and working principles of the above embodiment:

[0041] When the device is used, the staff places the PCB pad to be galvanized inside the support base 2, so that the bottom of the PCB pad is first in contact with the top of the four-legged pressing block 705, and the four-legged pressing block 705 pressed by the PCB pad slides downward on the inner wall of the support frame 702. During the descent, the upper and lower frames of the PCB pad will contact the long airbag strip 704. Since the outline of the long airbag strip 704 is convex upward and concave downward, when the PCB pad is pressed by the four-legged pressing block 705, the upper and lower frames of the PCB pad will contact the long airbag strip 704. The protruding part of the long airbag strip 704 is squeezed, so that the protruding part of the long airbag strip 704 is deformed toward the side of the C-shaped plate 703, and the PCB pad passes smoothly. Then the long airbag strip 704 is reset under the action of elasticity and covers the top of the PCB pad frame. With the four-foot pressure block 705 continuously pressing the sealing package 706, the sealing package 706 is squeezed and deformed, and the air generated in the cavity opened inside is discharged into the long airbag strip 704 through the air delivery duct 707. , with the input of air, the long airbag strip 704 gradually changes from an unsaturated state to an expanded state. When the PCB pad finally falls on the surface of the support frame 702, the expanded long airbag strip 704 cooperates with the support frame 702 to press and fix the PCB pad. Then the staff rotates the fixing buckle 801 so that the fixing buckles 801 on both sides can rotate ninety degrees, and finally the tip of the fixing buckle 801 falls on the surface of the PCB pad, which plays a role of longitudinal limit to prevent it from moving up and down. At the same time, the long airbag strip 704 and the support frame 702 can be used to firmly fix the PCB pad inside the support base 2, which plays a role of lateral limit to prevent it from moving around, which is convenient for subsequent operations. Compared with the problem that the clamp used in the prior art needs a power source during operation, this equipment is convenient for personnel to operate, saves energy, reduces the failure rate, and thus increases the use efficiency of the equipment, so that the reliability is improved;

[0042] In addition, when the support base 2 needs to fix PCB pads of different sizes, before using the equipment, the staff loosens the bolts 903 so that the sliding block 902 can slide with the C-shaped plate 703 on the outer wall of the short guide rail 901. After the C-shaped plate 703 is adjusted into place, the bolts 903 are tightened in sequence, so that the sliding block 902 and the C-shaped plate 703 can be firmly fixed. By adjusting the size between the two C-shaped plates 703, the support base 2 can meet the needs of fixing PCB pads of different widths, which greatly improves the utilization efficiency of the equipment. The fixing buckle 801 has a certain length, so that the fixed buckle 801 after rotation can press and fix the two side frames of the PCB pads of different lengths, which further improves the practicality.

[0043] Because the PCB pads need to be thoroughly cleaned before galvanizing to prevent dust and other impurities from adhering to the surface of the PCB pads and affecting the final galvanizing effect of the PCB pads, when the PCB pads are fixed, the staff starts the electric push rod 604 through the control panel, so that the extended end of the electric push rod 604 pushes the rectangular vertical plate 3 forward. Since the bottom of the rectangular vertical plate 3 is fixedly connected to the sliding seat 602, and the sliding seat 602 slides on the outer wall of the long guide rail 601, the rectangular vertical plate 3 can be stable during movement. By pushing the rectangular vertical plate 3 to one side of the support base 2, the semi-enclosed cover plate 301 gradually slides on the outer wall of the top of the support base 2, and before the hollow cylinder 401 contacts the PCB pads, the dust collection is started. The dust collector 406 cooperates with the sealing tube 405 to suck in the dust and other impurities that the hollow cylinder 401 contacts through the through hole 402, which is convenient for subsequent unified collection. As the hollow cylinder 401 moves on the surface of the PCB pad, the dust and other impurities on the surface of the PCB pad can be adsorbed. The semi-enclosed area formed by moving the semi-enclosed cover plate 301 to the top of the support base 2 is used to cooperate with the hollow cylinder 401 to rotate and continuously absorb dust, which can maintain the PCB pad clean. When the rotating wheel 501 contacts the top of the support base 2, the rotating wheel 501 can roll on the surface of the support base 2 under the action of friction. As the rotating wheel 501 continues to roll, the hollow cylinder 401 can carry The cleaning strip 403 makes a circular motion, and because the hollow cylinder 401 and the sealing end cover 404 rotate in coordination, the upper half of the sealing tube 405 is fixed by the semi-enclosed cover plate 301 during the rotation of the hollow cylinder 401, so that the sealing tube 405 can always remain in an upright state. In addition, when the sealing tube 405 in an upright state cooperates with the sealing end cover 404, the problem of synchronous rotation of the sealing tube 405 and the hollow cylinder 401 can be avoided, thereby reducing the probability of leakage of the sealing tube 405 and improving the stability of use. The cleaning strip 403 is circulated to contact the surface of the PCB pad, so that the dust on the surface of the PCB pad can be fully cleaned, and the cleaned dust is adsorbed by the through hole 402, thereby avoiding dust Dust diffusion, causing pollution in a wider range, and at the same time, the use of the rotating cleaning bar 403 can avoid the same cleaning bar 403 from repeatedly contacting the PCB board welding plate, which is beneficial to improving the service life of the cleaning bar 403. At the same time, the cleaning bar 403 will conflict with the cross bar 407 during the rotation of the hollow cylinder 401. After the cross bar 407 contacts the cleaning bar 403, the cleaning bar 403 will shake, so that the cleaning bar 403 will shake off the floating dust adhering to itself, and absorb and collect it through the through hole 402. In addition, the cleaning bar 403 is designed to be movable and detachable, and can be replaced after a period of use, ensuring that the cleaning bar 403 can have a good cleaning effect. After cleaning is completed, as the semi-enclosed cover plate 301 continues to move on the surface of the support base 2,The galvanizing equipment body 302 can evenly galvanize the surface of the PCB pad after cleaning. By cleaning the surface of the PCB pad, the solder adhesion can be improved, and the situation of easy peeling or formation of bad points can be avoided, which helps to improve the stability of the overall welding connection.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
