Description

Technical Field

[0001] The invention relates to the technical field of PCB board processing, and in particular to a cooling device and process for a PCB board laminator. Background Art

[0002] PCB board is a basic material that supports and connects electronic components. It is made through a printing process on an insulating substrate. PCB board usually consists of a substrate material with insulating properties and one or more metal conductive layers. Circuit patterns are formed through chemical corrosion or mechanical processing according to design requirements. These circuit patterns connect different electronic components to realize the functions of electronic equipment.

[0003] When PCB boards are processed, they need to be laminated, that is, the multi-layer PCB boards, inner layers, pre-laid copper foils, and pre-impregnated paper materials are pressed together at high temperature to achieve adhesion between layers and form an integrated structure. After lamination, the PCB boards need to be quickly cooled due to the high temperature and high pressure environment they are in, so as to maintain the stability of the board, solidify the resin and improve production efficiency.

[0004] At present, natural cooling and medium cooling are mainly used to cool the laminated PCB board. The current cooling process has the following problems: 1. Since the PCB board is in a high temperature and high pressure environment during lamination, it is easy for the board to undergo thermal expansion and deformation. However, in the current cooling process, the PCB board is not limited and flattened, so it is easy for the PCB board to deform during the cooling process, resulting in the problem of scrapping the PCB board.

[0005] 2. The current natural cooling of the environment has a low cooling efficiency for PCB boards, which can easily lead to low overall production efficiency. The cooling treatment with the addition of a medium usually requires the use of additional media to exchange heat between the PCB board, so the overall cooling cost is high. Summary of the invention

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0034] like Figure 1 and Figure 2 As shown, a cooling device for a PCB laminator comprises:

[0035] The U-shaped base 1 has an opening facing downwards, and two left-right symmetrical L-shaped connecting plates are fixedly arranged on the upper end surface of the U-shaped base 1.

[0036] A base plate 2 is fixedly arranged between the two connecting plates, a plurality of flow holes 20 arranged in a matrix are opened on the base plate 2, an auxiliary mechanism 3 for assisting PCB board cooling is arranged on the base plate 2, two left-right symmetrical column groups are slidably arranged between the base plate 2 and the U-shaped base 1, the column group includes two front-to-back symmetrical lifting columns 4, a lifting plate 40 is fixedly arranged on the upper end surfaces of the two corresponding lifting columns 4, and a clamping mechanism 5 is arranged on the left and right lifting plates 40.

[0037] During operation, the PCB board after lamination by the laminator is first placed on the base plate 2, and then the clamping mechanism 5 positions and clamps the PCB board so that the PCB board is located in the area where the circulation hole 20 is opened on the base plate 2. At the same time, the PCB board is pressed down to keep the PCB board flat during the cooling process. Then the auxiliary mechanism 3 works to make the air around the PCB board flow quickly, flowing downward from the top around the PCB board and out through the circulation hole 20, so as to take out the heat on the PCB board, that is, completing the rapid cooling operation of the PCB board. After the cooling of the PCB board is completed, the PCB board is taken out, the device is reset, and other PCB boards that need to be quickly cooled are placed for cooling.

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, the auxiliary mechanism 3 includes a cooling box 30, and a cooling box 30 with an upper end opening and a hollow interior is fixedly provided on the lower end surface of the base plate 2, and air outlet holes 31 are provided on the front and rear end surfaces of the cooling box 30, and the air outlet holes 31 are connected to an external air pump, and a plurality of fixed plates 32 arranged equidistantly from left to right are fixedly provided between the base plate 2 and the lower end surface of the inner cavity of the cooling box 30, and a plurality of fixed strips 33 arranged equidistantly from front to back are fixedly provided between two adjacent fixed plates 32, and the fixed plates 32 and the fixed strips 33 are staggered with the flow holes 20, and two left-right symmetrical moving columns 34 are movably installed on the front and rear end surfaces of the base plate 2, and the end surfaces of the two moving columns 34 away from the base plate 2 are fixedly provided with L-shaped plates 35, and the rear end surfaces of the horizontal parts of the two corresponding L-shaped plates 35 on the left and right are fixedly provided with a fitting plate 36, and a spring 37 is fixedly provided between the L-shaped plate 35 and the base plate 2.

[0039] like Figure 4 and Fig. 9As shown, a U-shaped pad 38 is provided on the base plate 2, and a driving group 39 is provided on the base plate 2. The driving group 39 includes a placement groove 390. Two left-right symmetrical placement grooves 390 are provided on the base plate 2 and the U-shaped base 1. A threaded shaft 391 is rotatably provided on the lower end surface of the lifting plate 40. Matching plates 392 are fixedly provided on both the left and right end surfaces of the pad 38, and the matching plates 392 are threadedly matched with the corresponding threaded shafts 391. The threaded shafts 391 are connected to an external motor. A connecting plate is fixedly provided on the lower end surfaces of the two corresponding lifting columns 4. A telescopic guide rod 393 symmetrical to the connecting plate is fixedly provided at the lower end of the horizontal part of the U-shaped base 1, and the telescopic end of the telescopic guide rod 393 is fixedly connected to the corresponding connecting plate.

[0040] During operation, first, the telescopic guide rod 393 works to retract its telescopic end, so that its telescopic end drives the connecting plate and the corresponding lifting column 4 to rise, so that the lifting plate 40 drives the clamping mechanism 5 thereon to rise, and at the same time, the external motor works to drive the threaded shaft 391 to rotate forward, and the threaded cooperation between the threaded shaft 391 and the matching plate 392 makes the matching plate 392 move downward, that is, during the rising process of the lifting plate 40, the matching plate 392 drives the pad 38 thereon to remain on the upper end surface of the base plate 2, and then the PCB board is placed on the pad 38, and the telescopic guide rod 393 works to make the telescopic end extend, and at the same time, the external motor drives the threaded shaft 391 to reverse, that is, during this process, the lifting plate 40 While driving the clamping mechanism 5 to move downward, the pad 38 is maintained on the upper end surface of the base plate 2, so that the clamping mechanism 5 quickly clamps and positions the PCB board, and makes the center position of the PCB board coincide with the center position of the pad 38, and then the telescopic guide rod 393 works to retract its telescopic end, so the lifting plate 40 drives the pad 38, the clamping mechanism 5 and the PCB board to move up a certain distance synchronously, and the external air pump works to pump out the air in the cooling box 30, that is, in this process, the air quickly moves from the top of the PCB board to the surrounding areas of the PCB board and flows into the cooling box 30 through the circulation holes 20, thereby improving the cooling efficiency of the PCB board by accelerating the air flow rate around the PCB board.

[0041] The spring 1 37 is set to make the L-shaped plate 35 drive the corresponding bonding plate 36 to keep in contact with the lifting plate 40. Therefore, the front and rear bonding plates 36 are kept in contact with the lifting plate 40 so that the upper area of ​​the PCB board is a space area with an upper opening and closed around it, which is convenient for the external air pump to work so that the air flow rate around the PCB board becomes faster. In the cooling process, the lifting plate 40 drives the pad 38, the clamping mechanism 5 and the PCB board to move up a certain distance synchronously so that the PCB board maintains a certain distance from the flow hole 20 below, avoiding the problem that the PCB board is close to the flow hole 20 and the air flows quickly at the flow hole 20 to generate a large suction force on the PCB board, causing the PCB board to sink downward. At the same time, it is convenient to cool the lower end surface of the PCB board, avoiding the problem that the PCB board is blocked by the flow hole 20 due to the adhesion of the PCB board to the flow hole 20 and cannot be cooled.

[0042] The fixed strip 33 cooperates with the fixed plate 32 to increase the strength of the area where the flow hole 20 is opened on the base plate 2 when the clamping mechanism 5 and the auxiliary mechanism 3 are working, thereby maintaining the base plate 2's support for the pad 38 and the PCB board when the clamping mechanism 5 performs clamping, limiting and pressing operations. The space in the cooling box 30 is divided into multiple small spaces by the fixed strip 33 and the fixed plate 32, which facilitates the operation of the external air pump and increases the internal air flow rate.

[0043] like Figure 5 and Figure 8 As shown, the clamping mechanism 5 includes a side groove 50, and the opposite surfaces of the two lifting plates 40 are each provided with two front-to-rear symmetrical side grooves 50, a side displacement block 500 is slidably arranged in the side groove 50, a clamping column 51 is movably installed on the side displacement block 500, and a lower pressing plate 510 is fixedly arranged on the opposite surfaces of the left-right symmetrical clamping columns 51, and a vertical block 52 which is opposite to the adjacent lifting plates 40 and the bonding plates 36 is fixedly arranged on the lower end surface of the lower pressing plate 510, and a clamping column 53 is movably installed on the vertical block 52, and a clamping plate 530 is fixedly arranged on the end surface of the clamping column 53 away from the corresponding lifting plate 40 or the bonding plate 36, and a spring 2 54 is fixedly arranged between the clamping plate 530 and the corresponding clamping column 53, a synchronization group 55 is arranged on the lower pressing plate 510, and a driving group 2 56 for driving the two adjacent lower pressing plates 510 to approach each other is arranged on the two lifting plates 40.

[0044] like Figure 6 As shown, the synchronization group 55 includes a synchronization groove 550, and the upper end surface of the lower pressure block is provided with a synchronization groove 550 corresponding to the corresponding clamping plate 530, and the synchronization groove 550 is in the same axial direction as the corresponding clamping column 53, and a synchronization bar 551 fixedly connected to the corresponding clamping plate 530 is slidably arranged in the synchronization groove 550, and a telescopic rod 552 is fixedly arranged between the two relative synchronization bars 551.

[0045] like Figure 7 As shown, the driving group 2 56 on the left side is used for explanation. The driving group 2 56 on the left side includes a fixed block 560. The left end surface of the lifting plate 40 on the left side is fixedly provided with a fixed block 560. A bidirectional threaded shaft 561 is fixedly provided on the fixed block 560. The bidirectional threaded shaft 561 is connected to the external motor 2. Two front-to-rear symmetrical sliding blocks 562 are slidably provided on the left end surface of the lifting plate 40 on the left side, and a driving block 563 is fixedly provided on the sliding block 562. The driving block 563 and the bidirectional threaded shaft 561 are threadedly matched. The driving block 563 is fixedly connected to the corresponding side shift block 500 through an L-shaped strip. The lifting plate 40 is provided with a driving group 3 57 for driving the two corresponding lower pressure plates 510 on the same side to move right.

[0046] like Figure 7 As shown, the driving group three 57 includes a trapezoidal guide plate 570, and the left end surface of the lifting plate 40 on the left side is fixedly provided with an isosceles trapezoidal trapezoidal guide plate 570 through a connecting block, and the inclined surface of the trapezoidal guide plate 570 is opposite to the lifting plate 40, and the end surface of the clamping column 51 away from the lateral displacement block 500 is fixedly provided with a triangular block 571 through a square block, and the triangular block 571 and the inclined surface of the trapezoidal guide plate 570 cooperate with each other, and a spring three 572 is commonly provided between the lateral displacement block 500 and the corresponding square block.

[0047] like Figure 4 As shown, a downward pressing group 58 is commonly provided between the two lifting plates 40, and the downward pressing group 58 includes a downward moving groove 580. The opposite surfaces of the two lifting plates 40 are provided with downward moving grooves 580, and downward moving plates 581 are slidably arranged in the two downward moving grooves 580. A cross plate 582 is commonly fixedly arranged between the two downward moving plates 581, and spring mounting plates are fixedly arranged between the opposite surfaces of the two lifting plates 40 and the upper end surfaces of the downward moving plates 581, and a spring four 583 is commonly fixedly arranged between the two corresponding spring mounting plates.

[0048] like Figure 4 and Fig. 9 As shown, the front and rear inner walls of the rectangular area of ​​the pad 38 are fixedly provided with a U-shaped mating strip 59, which cooperates with the cross plate 582, and the upper end surface of the mating strip 59 is flush with the upper end surface of the pad 38.

[0049] During operation, after the PCB board is placed on the pad 38, the drive group 1 39 works to make the lifting plate 40 drive the clamping mechanism 5 thereon to move downward, which is illustrated by the drive group 2 56 and the drive group 3 57 on the left side. During the downward movement of the lifting plate 40, the external motor 2 works to drive the bidirectional threaded shaft 561 to rotate forward, and the drive block 563 is moved by the threaded cooperation between the bidirectional threaded shaft 561 and the corresponding drive block 563, and the corresponding two drive blocks 563 move toward each other, and the drive block 563 drives the side shift block 500 to move synchronously through the corresponding L-shaped bar, so the side shift block 500 drives the clamping column 51 thereon to move synchronously, and the clamping column 51 drives the lower pressure plate 510 thereon to move synchronously in the front-to-back direction, that is, the clamping plate 530 in the front-to-back direction on the lower pressure plate 510 is attached to the PCB board and the spring 2 54 is provided so that the clamping plate 530 has a clamping force on the PCB board, thereby limiting the front-to-back direction of the PCB board.

[0050] And in the process of the side shift block 500 driving the corresponding clamping column 53 to move, the clamping column 53 drives the corresponding triangular block 571 to move synchronously through the square block, and a spring 572 is provided so that the square block and the side shift block 500 have an area to keep away, that is, the triangular block 571 and the corresponding inclined surface of the trapezoidal guide plate 570 are kept in close contact, so that in the process of the two triangular blocks 571 moving toward each other, the inclined surface of the triangular block 571 cooperates with the inclined surface of the trapezoidal guide plate 570 so that the triangular block 571 drives the clamping column 53 to move rightward through the square block, so the two clamping columns 53 drive the lower pressure plate 510 to move right synchronously, and the lower pressure plate 510 moves left and right. The clamping plate 530 in the direction is attached to the PCB board and the spring 2 54 is provided so that the clamping plate 530 has a force on the PCB board to move it to the right. Therefore, the front and rear directions of the PCB board are first limited by the cooperation between the left and right clamping plates 530. At the same time, the left clamping plate 530 has a pushing force on the PCB board to the right, and the right clamping plate 530 has a force on the PCB board to move it to the left. Therefore, the left and right directions of the PCB board are limited, so that the placed PCB board is located above the pad 38 and the PCB board is located at the center position of the pad 38, that is, the supporting effect of the pad 38 on the PCB board is maintained.

[0051] When the lifting plate 40 drives the lower pressing plate 510 to move downward, the lower pressing plate 510 cooperates with the pad 38 to press down and flatten the four corners of the placed PCB board, thereby avoiding the problem of bending of the four corners of the PCB board during the cooling process.

[0052] The telescopic rod 552 arranged in the synchronization group 55 enables the corresponding two synchronization bars 551 to cooperate with each other, so that the corresponding two clamping plates 530 move synchronously, that is, the corresponding different groups of clamping plates 530 on the end surfaces around the PCB board move synchronously, that is, the four sides of the PCB board can be kept parallel to the four sides of the pad 38, so that the PCB board can be accurately placed on the pad 38.

[0053] When the lifting plate 40 drives the lower pressure plate 510 to move downward synchronously, the lifting plate 40 drives the cross plate 582 to move downward synchronously through the lower plate 581. After the cross plate 582 contacts the upper end surface of the PCB board, the lifting plate 40 continues to move downward, so the spring four 583 is compressed. The elastic force generated by the compression of the spring four 583 causes the cross plate 582 to exert a downward pressure on the PCB board. At the same time, the matching strip 59 cooperates with the cross plate 582 to clamp the PCB board and divide the PCB board into multiple smaller rectangular areas, thereby providing stable support for the PCB board. Therefore, it is convenient to cool the upper and lower end surfaces of the PCB board while avoiding the problem of deformation of the PCB board after cooling.

[0054] In addition, the present invention also provides a PCB laminator cooling process, comprising the following steps: Step S1: placing the PCB board, quickly taking the laminated PCB board out of the laminator, ensuring that the PCB board is not damaged during the process, and placing the PCB board on a pad 38.

[0055] Step S2: limit the PCB board, and through the operation of the driving group 1 39, the lifting plate 40 drives the clamping mechanism 5 to move downward. In this process, through the operation of the driving group 2 56 and the driving group 3 57, the pressing plate 530 on the left has a pushing force on the PCB board to the right, and the pressing plate 530 on the right has a force on the PCB board to move to the left. Therefore, the left and right directions of the PCB board are limited, so that the placed PCB board is located above the pad 38 and the PCB board is located at the center of the pad 38. The synchronization group 55 is used to make the four sides of the PCB board parallel to the four sides of the pad 38, and the lower pressure plate 510 cooperates with the pad 38 to press down the placed PCB board, thereby completing the limitation of the PCB board.

[0056] Step S3: Cooling operation, the telescopic guide rod 393 works so that the lifting plate 40 drives the pad 38, the clamping mechanism 5 and the PCB board to move up a certain distance synchronously, and the external air pump works to pump out the air in the cooling box 30, that is, in this process, the air moves quickly from the top of the PCB board to the surrounding of the PCB board and flows into the cooling box 30 through the circulation hole 20, thereby taking out the heat on the PCB board, that is, completing the rapid cooling operation of the PCB board, and after the cooling of the PCB board is completed, take it out, reset the device and place other PCB boards that need to be quickly cooled for cooling operation.
