Description

Technical Field

[0002] During the manufacturing process of printed circuit boards, the laminating process is a key link to ensure the surface insulation protection and anti-corrosion performance of the circuit boards. Traditional laminating processes mostly use manual or semi-automatic equipment, which has the following technical defects:

[0003] 1. Existing trolley systems mostly rely on single-board intermittent transmission, with low processing efficiency and difficulty in meeting the high-throughput requirements of modern PCB production lines;

[0004] 2. There is a lack of dynamic coordination between the laminating tank and the conductive system, and poor contact is likely to occur in the conductive section, resulting in uneven thickness of the electroplated laminating layer;

[0005] 3. Conventional trolleys lack an active oscillation function, with insufficient membrane liquid permeability, prone to problems such as bubble residues and decreased laminating adhesion;

[0006] 4. There is spatial interference between the transmission system and the processing tank, making equipment maintenance difficult and unable to achieve continuous processing of multiple processes.

[0007] Although prior arts such as patent DE102019132112B4 have tried to improve the trolley structure, there are still problems such as insufficient stability of double-board synchronous clamping, uncontrollable conductive contact pressure, and equipment vibration during process conversion affecting the laminating quality. Especially when processing micro-hole high-density circuit boards, it is difficult for traditional equipment to achieve uniform penetration of the membrane liquid between complex circuits, affecting the product yield.

[0061]

[0062] Example 3

[0062] Please refer to Figures 1 - 8The present invention provides a fully automatic pulley for laminating printed circuit boards, further comprising: a chain circulation transmission system 2 and a horizontal slide rail module of the fully automatic pulley 4, the horizontal slide rail module being installed in the middle of the linear frame 1, a transmission chain 201 being arranged at the lower part of the chain circulation transmission system 2 through a sprocket drive, the transmission chain 201 being arranged above the trough body 3 in a counterclockwise manner, a pin seat 202 being equidistantly arranged at the lower part of the transmission chain 201, an active pin 203 being rotatably installed on the pin seat 202 through a torsion spring, and the rotation angle of the active pin 203 being limited to the third quadrant of the plane rectangular coordinate system;

[0063] The horizontal slide rail module includes a limit guide rail 401, a limit slider 402, a mounting column 403, an auxiliary slide rail 404 and an auxiliary roller 405. Two limit guide rails 401 are fixed on the upper part of the middle line body frame 1, and the limit guide rails 401 are distributed in equal length with the trough body 3. The upper part of the limit guide rail 401 is slidably installed with a limit slider 402, and the front walls of the two limit sliders 402 on the same vertical line are fixed with mounting columns 403. Auxiliary slide rails 404 connected end to end are fixed on the upper right wall of the trough body 3. The bottom of the mounting column 403 is slidably connected to the auxiliary slide rail 404, and the auxiliary rollers 405 are rotatably clamped in the left and right inner parts of the lower wall of the mounting column 403, and the left auxiliary roller 405 is restricted between the right end baffle of the groove part of the trough body 3 and the auxiliary slide rail 404.

[0064] When in use, the active pin 203 of the chain circulation transmission system 2 pushes the driven plate 414 to move, so that the double-plate vibration mechanism moves as a whole, pushing the pulley mounting column 403 to slide along the auxiliary slide rail 404, and the limiting slider 402 slides along the limiting guide rail 401. When the pulley mounting column 403 slides, the auxiliary roller 405 can reduce the friction at the bottom of the pulley mounting column 403 to ensure the smooth horizontal movement of the fully automatic pulley 4. The transmission mechanism of such a horizontal circuit board transmission system is mostly concentrated on the support column in the middle of the line body, which occupies a small space, has a simple structure, flexible deployment, stable transmission, and simple maintenance, solving the defect of traditional equipment "difficult maintenance due to spatial interference".

[0065] Example 4

[0066] See also Figures 1 - 3 and Figures 5 - 8, the present invention provides a fully automatic trolley for laminating a printed circuit board, further comprising: a vertical lifting mechanism and a lifting and conducting mechanism 5 of the fully automatic trolley 4. The vertical lifting mechanism is installed at the left part of the horizontal slide rail module. The vertical lifting mechanism includes a support 406, a winding and unwinding power roller 407, a guide roller 408, a lifting cable 409, a lifting slider 410, a vertical lifting slide rail 411 and a conductive connection column 412. Supports 406 are fixed at the top of the left and right walls of the mounting column 403. A winding and unwinding power roller 407 is installed on the right support 406, and a guide roller 408 is installed on the left support 406. A lifting cable 409 is wound around the winding and unwinding power roller 407, and the right end of the lifting cable 409 is fixed to the winding and unwinding power roller 407. The left end of the lifting cable 409 passes through the upper left part of the guide roller 408 and is fixed with a lifting slider 410. The left wall of the mounting column 403 is fixed with a vertical lifting slide rail 411, and the right part of the lifting slider 410 is slidably connected in the vertical lifting slide rail 411. The left wall of the lifting slider 410 is fixed with a conductive connection column 412, and the conductive connection column 412 is made of brass, which can link the lifting slider 410 with the double-board carrier 413 and conduct electricity for the double-board carrier 413 and the carrier plate hanger 419 while the conductive section groove 302 is in use;

[0067] The lifting and conducting mechanism 5 includes a cathode copper bar 505, a conductive copper bar 501, a power connection slot 502, a lifting power connection plate 503 and an elastic pressing power connection piece 504. The conductive copper bar 501 is installed on the upper wall of the right part of the conductive section groove 302. The cathode copper bar 505 is fixedly and electrically connected to the conductive copper bar 501. The upper end of the cathode copper bar 505 is connected to a rectifier to supply power to the conductive copper bar 501. A power connection slot 502 is opened in the left part of the conductive copper bar 501. A lifting power connection plate 503 is fixed between the lower walls of the right ends of the two conductive connection columns 412. An elastic pressing power connection piece 504 is fixed to the bottom of the lifting power connection plate 503, and the elastic pressing power connection piece 504 is intermittently clamped with the power connection slot 502 as the lifting slider 410 moves up and down.

[0068] More perfectly, both the lifting power connection plate 503 and the elastic pressing power connection piece 504 are made of brass. A rectangular parallelepiped groove is opened at the lower left corner of the lifting power connection plate 503. The elastic pressing power connection piece 504 is a torsion spring plate with an upward opening. The right plate of the torsion spring plate is fixed to the right wall of the elastic pressing power connection piece 504, and the left plate of the torsion spring plate is intermittently and elastically rotatably installed in the rectangular parallelepiped groove of the lifting power connection plate 503, so that the elastic pressing power connection piece 504 can rotate and retract into the rectangular parallelepiped groove when pressed, and the elastic force generated by the pressing makes the lifting power connection plate 503 closely contact with the conductive copper bar 501.

[0069] When in use, the chain circulation transmission system 2 and the horizontal slide rail module cooperate to transfer the fully automatic pulley 4 horizontally to the top of the processing segment slot 301 or the conductive segment slot 302, and the retractable and reeling power roller 407 of the vertical lifting mechanism releases the lifting rope 409, so that the lifting slider 410 can be vertically dropped along the vertical lifting slide rail 411 under the action of gravity, driving the conductive connection column 412 and the double-ply plate vibration mechanism to drop synchronously, and immersing the printed circuit board into the processing liquid. When the vertical lifting mechanism drives the double-ply plate vibration mechanism to drop in the conductive segment slot 302, it can drive the lifting power board 503 to drop synchronously, and finally the elastic top presses the electrical sheet. 504 is inserted into the power connection slot 502 from top to bottom, and the elastic top pressing power connection sheet 504 is pressed, and its elastic force makes the lifting power connection plate 503 and the conductive copper bus 501 close to each other. Even if the chain circulation transmission system 2 and the horizontal slide rail module continue to drive the fully automatic pulley 4 to move horizontally, the elastic top pressing power connection sheet 504 can maintain the dynamic contact pressure between the lifting power connection plate 503 and the conductive copper bus 501, so that when the circuit board is electroplated, the contact resistance fluctuation is reduced, the conductivity is stable, the current distribution on the circuit board is uniform, and the coating layer is highly uniform, which overcomes the problem of "uncontrollable conductive pressure and poor contact of the conductive section leading to uneven coating" in traditional equipment.

[0070] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0071] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
