[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0024] As the background technology, the traditional printed circuit board lamination process is mostly carried out by manual or semi-automatic equipment, which has the following technical defects: 1. The existing pulley system mostly relies on intermittent transmission of single boards, which has low processing efficiency and is difficult to adapt to the high-throughput requirements of modern PCB production lines; 2. The coating tank body and the conductive system lack dynamic coordination, which may cause poor contact in the conductive section, resulting in uneven thickness of the electroplated coating layer; 3. Conventional pulleys lack active oscillation function, and the membrane liquid permeability is insufficient, which easily leads to residual bubbles and decreased adhesion of the membrane; 4. There is spatial interference between the transmission system and the processing tank, which makes equipment maintenance difficult and makes it impossible to achieve continuous processing of multiple processes. Example 1

A lifting conductive mechanism 5 is provided between the upper portion of the conductive section tank 302 and the fully automatic pulley 4. Among them, the line body frame 1 is used to support various components on the line body; The chain circulation transmission system 2 is used to intermittently push the fully automatic pulley 4 to horizontally step and move above a plurality of processing segment slots 301 and conductive segment slots 302; Among them, the tank body 3 is used to process various processing steps on the circuit board coating; Among them, the fully automatic pulley 4 is used to carry and fix two circuit boards at the same time, drive the circuit boards to move between the processing sections, and automatically vibrate the circuit boards during the coating process to improve the coating process effect of the circuit boards; The lifting conductive mechanism 5 is used to stably connect the circuit board with the cathode conductive copper bar to complete the conduction when the fully automatic pulley 4 drives the circuit board into the conductive segment slot 302.

[0026] When in use, the chain circulation transmission system 2 cooperates with the full-automatic pulley 4 to drive two printed circuit boards at the same time. According to the coating processing procedure, the full-automatic pulley 4 is pushed to pass through the degreasing, micro-etching, cleaning and air-drying stations of the processing segment groove 301 in sequence, and the lifting and conductive mechanism 5 of the conductive segment groove 302 is used to perform conductive coating. After the printed circuit board completes all the processes, the full-automatic pulley 4 returns to the loading station, thereby realizing multi-process continuous processing of the printed circuit board coating processing, thereby improving equipment utilization and coating processing efficiency. Example 2

[0027] See also Figure 2-Figure 3 and Figure 5-Figure 8The present invention provides a fully automatic pulley for laminating a printed circuit board, further comprising: a double-ply plate vibration mechanism of the fully automatic pulley 4, the double-ply plate vibration mechanism comprising a double-plate carrier 413, a driven paddle 414, a linear vibrator 415, an L-shaped linkage plate 416, a latch 417, a sliding latch slot 418 and a carrier hanger 419, a double-plate carrier 413 is provided through the left portion of two conductive connecting columns 412, a driven paddle 414 is fixed on the top of the double-plate carrier 413, an active paddle pin 203 intermittently abuts against the side wall of the driven paddle 414, and pushes the driven paddle 414 to move in steps, an insulating fixing seat is provided on the inner side of the upper wall of the double-plate carrier 413, The insulating fixing seat is nested with two conductive connecting columns 412, and a linear vibrator 415 is installed at the bottom of the insulating fixing seat.

Four pairs of pins 417 are fixed to the vertical plate surface of the L-shaped linkage plate 416, and a carrier bracket 419 is fixed between the outer parts of the four pairs of pins 417. Four vertical straight key-type sliding slots 418 are opened on the left and right walls of the double-plate carrier 413, and the four pairs of pins 417 on the left are respectively slidably connected to the four sliding slots 418 on the left, and the four pairs of pins 417 on the right are respectively slidably connected to the four sliding slots 418 on the right.

[0028] When in use, two board carrier racks 419 are respectively fixed with printed circuit boards at the loading stations of the line body, and two printed circuit boards can be loaded and processed at the same time, thereby improving the coating processing efficiency to meet the high throughput requirements of modern PCB board production lines. After the circuit board is immersed in the liquid of the processing segment tank 301 or the liquid of the conductive segment tank 302 for coating processing, the double-ply plate vibration mechanism starts the linear vibrator 415 according to the preset program, so that its output end performs up and down reciprocating linear motion, and the output end of the linear vibrator 415 drives the L-shaped linkage plate 416 , the latch 417 and the carrier hanger 419 are linked, but the up and down movement of the latch 417 is restricted in the sliding slot 418, so that the printed circuit board vibrates up and down while the double-board carrier 413 and the driven paddle 414 can remain stationary.

Example 3

[0029] See also Figure 1-Figure 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; 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.

[0030] 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 that "spatial interference causes maintenance difficulties". Example 4

[0031] See also Figure 1-Figure 3 and Figure 5-Figure 8The present invention provides a fully automatic pulley for laminating a printed circuit board, further comprising: a vertical lifting mechanism and a lifting conductive mechanism 5 of the fully automatic pulley 4, the vertical lifting mechanism being installed on the left side of the horizontal slide rail module, the vertical lifting mechanism comprising a support 406, a retractable and rewinding power roller 407, a guide roller 408, a lifting rope 409, a lifting slider 410, a vertical lifting slide rail 411 and a conductive connecting column 412, the tops of the left and right walls of the mounting column 403 are both fixed with supports 406, the retractable and rewinding power roller 407 is installed on the right support 406, the guide roller 408 is installed on the left support 406, and the retractable and rewinding power roller 407 is installed on the left support 406. A lifting rope 409 is wound around it, and the right end of the lifting rope 409 is fixed on the retracting and unwinding power roller 407, and the left end of the lifting rope 409 is fixed with a lifting slider 410 through the upper left part of the guide roller 408, a vertical lifting rail 411 is fixed to the left wall of the mounting column 403, and the right part of the lifting slider 410 is slidably connected in the vertical lifting rail 411, and a conductive connecting column 412 is fixed to the left wall of the lifting slider 410, and the conductive connecting column 412 is made of brass, which can make the lifting slider 410 and the double-plate carrier 413 linked, and at the same time, conduct electricity to the double-plate carrier 413 and the carrier hanger 419 in the conductive segment slot 302; The lifting conductive mechanism 5 comprises a cathode copper bar 505, a conductive copper bar 501, an electrical connection slot 502, a lifting electrical connection board 503 and an elastic top pressing electrical connection sheet 504. The conductive copper bar 501 is installed on the upper wall of the right part of the conductive segment slot 302. The cathode copper bar 505 is fixedly electrically connected to the conductive copper bar 501. The cathode copper bar 505 is connected to a rectifier to supply power to the conductive copper bar 501. The left part of the conductive copper bar 501 is provided with an electrical connection slot 502. A lifting electrical connection board 503 is fixed between the lower walls of the right ends of the two conductive connecting columns 412. An elastic top pressing electrical connection sheet 504 is fixed to the bottom of the lifting electrical connection board 503. The elastic top pressing electrical connection sheet 504 is intermittently connected to the electrical connection slot 502 as the lifting slider 410 rises and falls.

[0032] More perfect, the lifting power board 503 and the elastic top pressing power sheet 504 are both made of brass, and a rectangular groove is opened at the lower left corner of the lifting power board 503.

The right side plate of the torsion spring plate is fixed to the right wall of the elastic top pressing power sheet 504, and the left side plate of the torsion spring plate is intermittently elastically rotatably installed in the rectangular groove of the lifting power board 503, so that the elastic top pressing power sheet 504 can be rotated and retracted into the rectangular groove when it is compressed, and the lifting power board 503 is tightly attached to the conductive copper bus 501 by its compressed elastic force.

[0033] 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.

[0034] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.
