Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing, and specifically relates to a turnover cooling machine for producing circuit boards and its usage method. Background Technique

[0002] A turnover cooling machine is a device specifically used for cooling during the production process of circuit boards, especially in the manufacturing process of printed circuit boards. The main purpose of this cooling machine is to help cool down the circuit boards with relatively high temperatures during the production process, ensuring that the circuit boards maintain a stable and high-quality state in different production links. Currently, with the accelerating replacement and increasing variety of electronic products, the circuit board production line needs to greatly improve production efficiency to increase the output of circuit boards.

[0003] When the existing device turns over the circuit board, the circuit board is usually carried by two clamping plates to turn it over. During this process, the circuit board cannot be clamped, which may cause the circuit board to collide or rub against machine components, resulting in scratches, fractures, or other physical damages on the board surface. Summary of the Invention

[0004] The purpose of the present invention is to provide a turnover cooling machine for producing circuit boards and its usage method to solve the problems raised in the above background technique.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a turnover cooling machine for producing circuit boards and its usage method, including a working box. On both sides of the top of the working box, there are respectively fixedly connected fixing frames. Inside the conveying member, there is a conveying member. Between the two fixing frames, there is a fixedly connected fixing plate. It also includes a turnover cooling mechanism. The turnover cooling mechanism includes a motor, a rotating shaft, a roller, a turnover plate, and a transmission component for turning over the circuit board. One end of the motor is fixedly connected to the outer wall of one side of the fixing plate. One end of the rotating shaft is fixedly connected to the output end of the motor. The inner wall of the roller is fixedly connected to the outer wall of the middle end of the rotating shaft. One end of the turnover plate is fixedly connected to the outer wall of the roller. There are eight turnover plates, and two turnover plates are set as a group.

[0007] Furthermore, the transmission component includes discs fixedly connected to both ends of the rotating shaft. The outer wall of the disc is rotatably connected to a belt. The inner wall of the end of the belt away from the disc is rotatably connected to a rotating frame. One end of the rotating frame penetrates and is rotatably connected to the inner wall of the working box.

[0008] Furthermore, one end of the outer wall of the rotating frame is fixedly connected to a reciprocating lead screw. The outer wall of the reciprocating lead screw is threadedly connected to a threaded table. The bottom of the threaded table is slidably connected to the bottom of the inner wall of the working box. On one side of the top of the threaded table, there is an annular groove.

[0009] Further, an auxiliary component is arranged inside the annular groove. The auxiliary component includes a special-shaped shell rotatably connected to the four-week inner wall of the annular groove. A sliding plate is slidably connected to the inner wall of the special-shaped shell. One side of the sliding plate is fixedly connected with a spring, and one end of the spring is fixedly connected to one side of the inner wall of the special-shaped shell. Two first coolers are respectively fixedly connected to both ends of the inner wall of the special-shaped shell close to the spring.

[0010] Further, a clamping component is arranged on the side wall of the sliding plate. The clamping component includes a connecting rod fixedly connected to the side of the sliding plate away from the spring. One end of the connecting rod is fixedly connected with an arc-shaped clamping shell, and a plurality of air holes are respectively arranged on one side of the arc-shaped clamping shell.

[0011] Further, one side of the inner wall of the arc-shaped clamping shell is communicated with a circular tube. One end of the circular tube penetrates through the connecting rod and extends into the interior of the special-shaped shell. Blocks are fixedly connected to both the top and the bottom of the arc-shaped clamping shell. A clamping groove is arranged on the side wall of the turning plate, and one end of the outer wall of the block is slidably connected to the inner wall of the clamping groove.

[0012] Further, a cooling component is arranged on the outer wall of the arc-shaped clamping shell. The cooling component includes a square plate fixedly connected to one side of the outer wall of the arc-shaped clamping shell. A square groove is arranged on one side of the square plate. A turning plate is rotatably connected to one side of the outer wall of the special-shaped shell. One end of the turning plate away from the special-shaped shell is rotatably connected with a slider, and one end of the outer wall of the slider is slidably connected to the inner wall of the square groove.

[0013] Further, a cross bar is fixedly connected to one side of the slider. One end of the cross bar away from the slider is fixedly connected with a pressing block. A fixed shell is fixedly connected between two adjacent turning plates. A return spring is fixedly connected to one side of the inner wall of the fixed shell. One end of the return spring is fixedly connected with a moving plate, and the outer wall of the moving plate is slidably connected to the inner wall of the fixed shell.

[0014] Further, a bearing frame is fixedly connected to the side of the moving plate away from the return spring. Two second coolers are respectively fixedly connected to both ends of the inner wall of the fixed shell close to the return spring. A plurality of bent pipes are communicated with both the top and the bottom of the fixed shell. A plurality of round holes are arranged on one side of the outer wall of the bent pipe.

[0015] A method for using a turning plate cooler for producing circuit boards includes the following steps:

[0016] Step 1: Perform the turning plate work on the circuit board. Convey the circuit board in the production process to the top of the conveying part. The conveying part drives the circuit board to move between two adjacent turning plates. At this time, start the motor. The motor drives the rotating shaft to rotate. The rotating shaft drives the roller to rotate. The roller drives the turning plate to rotate. The turning plate drives the circuit board to rotate, so that the circuit board moves to the top of another conveying part;

[0017] Step 2: Cool the circuit board. When the arc-shaped clamp holds the circuit board, due to the reaction force of the circuit board, the circuit board causes the arc-shaped clamp to drive the connecting rod to move towards the special-shaped shell. The connecting rod drives the sliding plate to move into the special-shaped shell. Due to the setting of the first cooler, the air flow inside the special-shaped shell is cooled, so that the cold air inside the special-shaped shell enters the inside of the round tube. The cold air enters the inside of the arc-shaped clamp through the round tube, and the cold air jets towards both ends of the circuit board through the air holes at the arc-shaped clamp;

[0018] Step 3: Improve the clamping stability. When the arc-shaped clamp and the special-shaped shell gradually approach, the generated extrusion force causes the rotating plate to rotate along the special-shaped shell, so that the rotating plate drives the slider to slide along the inner wall of the square groove. The slider drives the cross bar to move, and the cross bar drives the extrusion block to move. During the movement of the extrusion block, it will come into contact with one end of the circuit board and push the circuit board;

[0019] Step 4: Improve the cooling effect. When the circuit board moves under the extrusion of the extrusion block, the circuit board will come into contact with the side surface of the carrier, squeeze the carrier, and the carrier drives the moving plate to move. The moving plate slides inside the fixed shell. Due to the setting of the second cooler, the second cooler cools the air inside the fixed shell. At this time, the moving plate makes the cold air inside the fixed shell enter the inside of the elbow pipe. Due to the setting of the round hole, the cold air jets outwards through the round hole at the elbow pipe, and the cold air jets on the upper and lower surfaces of the circuit board.

[0020] The present invention has the following beneficial effects:

[0021] (1) In the present invention, the circuit board in the production process is conveyed to the top of the conveying member. The conveying member drives the circuit board to move between two adjacent turning plates. At this time, the motor is started. The motor drives the rotating shaft to rotate, the rotating shaft drives the roller to rotate, the roller drives the turning plate to rotate, and the turning plate drives the circuit board to rotate, so that the circuit board moves to the top of another conveying member for the turning plate operation. Due to the setting of the spring, the spring drives the sliding plate to move, the sliding plate drives the connecting rod to move, and the connecting rod drives the arc-shaped clamping shell to move. The two arc-shaped clamping shells can initially clamp the circuit board. When the rotating shaft rotates, the rotating shaft drives the disc to rotate, the disc drives the belt to rotate, the belt drives the rotating frame to rotate, and the rotating frame drives the reciprocating lead screw to rotate. When the disc rotates half a circle, the reciprocating lead screw will drive the threaded table to perform a reciprocating operation process. The threaded table drives the special-shaped shell to move, the special-shaped shell drives the sliding plate to move, the sliding plate drives the connecting rod to move, and the connecting rod drives the arc-shaped clamping shell to move. The two arc-shaped clamping shells move closer to each other, thereby clamping the circuit board, improving the clamping effect of the arc-shaped clamping shell on the circuit board, preventing the circuit board from shifting during the turning process and colliding with parts, resulting in damage to the outer surface of the circuit board. Due to the setting of the annular groove, the arc-shaped clamping shell drives the block to be located on the inner wall of the clamping groove at the turning plate for positioning work, enabling the special-shaped shell to rotate inside the annular groove, so that the arc-shaped clamping shell is always between two adjacent turning plates, improving the clamping stability of the arc-shaped clamping shell.

[0022] (2) In the present invention, when the arc-shaped clamping shell clamps the circuit board, due to the reaction force of the circuit board, the circuit board causes the arc-shaped clamping shell to drive the connecting rod to move towards the special-shaped shell, and the connecting rod drives the sliding plate to move into the special-shaped shell. Due to the setting of the first cooler, the air flow inside the special-shaped shell is cooled, and the cold air inside the special-shaped shell enters the inside of the round tube. The cold air enters the inside of the arc-shaped clamping shell through the round tube, and the cold air jets towards both ends of the circuit board through the air holes at the arc-shaped clamping shell, thereby cooling the circuit board. Due to the arc-shaped surface setting of the arc-shaped clamping shell, the circuit board will gradually move to the center of the arc-shaped surface of the arc-shaped clamping shell, facilitating the cold air to jet on the upper and lower surfaces of the circuit board and improving the cooling effect of the device on the circuit board.

[0023] (3) In the present invention, when the arc-shaped clamping shell and the special-shaped shell gradually approach, the generated extrusion force causes the rotating plate to rotate along the special-shaped shell, causing the rotating plate to drive the slider to slide along the inner wall of the square groove. The slider drives the cross bar to move, and the cross bar drives the extrusion block to move. During the movement of the extrusion block, it will come into contact with one end of the circuit board and push the circuit board, preventing the circuit board from slipping during the turning process and improving the stability of the circuit board turning.

[0024] (4) In the present invention, when the circuit board is moved by the extrusion of the extrusion block, the circuit board will come into contact with the side surface of the carrier, extruding the carrier, and the carrier drives the moving plate to move. The moving plate slides inside the fixed shell. Due to the arrangement of the second cooler, the second cooler cools the air inside the fixed shell. At this time, the moving plate allows the cold air inside the fixed shell to enter the inside of the elbow pipe. Due to the arrangement of the round holes, the cold air jets outwards through the round holes at the elbow pipe, and the cold air jets on the upper and lower surfaces of the circuit board to cool the circuit board, improving the comprehensiveness of the circuit board during cooling and enhancing the cooling effect of the device on the circuit board.

[0025] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the rotating frame 553 penetrates and is rotatably connected to the inner wall of the working box 1.

[0044] One end of the outer wall of the rotating frame 553 is fixedly connected to a reciprocating lead screw 554. The outer wall of the reciprocating lead screw 554 is threadedly connected to a threaded platform 555. The bottom of the threaded platform 555 is slidably connected to the bottom of the inner wall of the working box 1. An annular groove 556 is formed on one side of the top of the threaded platform 555.

[0045] An auxiliary component 56 is arranged inside the annular groove 556. The auxiliary component 56 includes a special-shaped shell 561 rotatably connected to the inner walls around the annular groove 556. A sliding plate 562 is slidably connected to the inner wall of the special-shaped shell 561. One side of the sliding plate 562 is fixedly connected to a spring 563.

Two first coolers 564 are respectively fixedly connected to both ends of the inner wall of the special-shaped shell 561 close to the spring 563.

[0046] The side wall of the sliding plate 562 is provided with a clamping component 57. When the rotating shaft 52 rotates, the rotating shaft 52 drives the disc 551 to rotate. The disc 551 drives the belt 552 to rotate. The belt 552 drives the rotating frame 553 to rotate. The rotating frame 553 drives the reciprocating lead screw 554 to rotate. When the disc 551 rotates half a turn, the reciprocating lead screw 554 will drive the threaded platform 555 to perform a reciprocating operation process. The threaded platform 555 drives the special-shaped shell 561 to move. The special-shaped shell 561 drives the sliding plate 562 to move. The sliding plate 562 drives the connecting rod 571 to move. The connecting rod 571 drives the arc-shaped clamping shell 572 to move. The two arc-shaped clamping shells 572 move closer to each other, thereby clamping the circuit board, improving the clamping effect of the arc-shaped clamping shell 572 on the circuit board, and preventing the circuit board from shifting during flipping. The clamping component 57 includes a connecting rod 571 fixedly connected to the side of the sliding plate 562 away from the spring 563. One end of the connecting rod 571 is fixedly connected with an arc-shaped clamping shell 572. When the arc-shaped clamping shell 572 clamps the circuit board, due to the reaction force of the circuit board, the circuit board causes the arc-shaped clamping shell 572 to drive the connecting rod 571 to move towards the special-shaped shell 561. The connecting rod 571 drives the sliding plate 562 to move into the interior of the special-shaped shell 561. Due to the setting of the first cooler 564, the air flow inside the special-shaped shell 561 is cooled, so that the cold air inside the special-shaped shell 561 enters the interior of the round tube 574. The cold air enters the interior of the arc-shaped clamping shell 572 through the round tube 574. The cold air jets towards both ends of the circuit board through the air holes 573 at the arc-shaped clamping shell 572, thereby cooling the circuit board. A plurality of air holes 573 are respectively opened on one side of the arc-shaped clamping shell 572.

[0047] One side of the inner wall of the arc-shaped clamping shell 572 is communicated with a round tube 574. One end of the round tube 574 penetrates through the connecting rod 571 and extends into the interior of the special-shaped shell 561. Both the top and the bottom of the arc-shaped clamping shell 572 are fixedly connected with clamping blocks 575. A clamping groove 576 is opened on the side wall of the flipping plate 54. One end outer wall of the clamping block 575 is slidably connected to the inner wall of the clamping groove 576.

[0048] In Embodiment 2, a cooling component 58 is provided on the outer wall of the arc-shaped clamping shell 572. The cooling component 58 includes a square plate 581 fixedly connected to one side of the outer wall of the arc-shaped clamping shell 572. A square groove 583 is opened on one side of the square plate 581. One side of the outer wall of the special-shaped shell 561 is rotatably connected with a rotating plate 582. One end of the rotating plate 582 away from the special-shaped shell 561 is rotatably connected with a slider 584. One end outer wall of the slider 584 is slidably connected to the inner wall of the square groove 583.

[0049] One side of the slider 584 is fixedly connected with a cross bar 585. One end of the cross bar 585 away from the slider 584 is fixedly connected with a pressing block 586. When the arc-shaped clamping shell 572 and the special-shaped shell 561 gradually approach, the generated extrusion force causes the rotating plate 582 to rotate along the special-shaped shell 561, so that the rotating plate 582 drives the slider 584 to slide along the inner wall of the square groove 583. The slider 584 drives the cross bar 585 to move, the cross bar 585 drives the pressing block 586 to move, and the pressing block 586 will contact one end of the circuit board during the movement process, pushing the circuit board to prevent the circuit board from slipping during the turning process, improving the stability of the circuit board turning. A fixed shell 587 is fixedly connected between two adjacent turning plates 54. One side of the inner wall of the fixed shell 587 is fixedly connected with a return spring 588. One end of the return spring 588 is fixedly connected with a moving plate 589, and the outer wall of the moving plate 589 is slidably connected to the inner wall of the fixed shell 587.

[0050] One side of the moving plate 589 away from the return spring 588 is fixedly connected with a bearing frame 5810. Two ends of one side of the inner wall of the fixed shell 587 close to the return spring 588 are respectively fixedly connected with a second cooler 5811. The top and bottom of the fixed shell 587 are both communicated with a plurality of bent pipes 5812. A plurality of round holes 5813 are opened on one side of the outer wall of the bent pipe 5812. When the circuit board is pushed and moved by the pressing block 586, the circuit board will contact the side surface of the bearing frame 5810, squeezing the bearing frame 5810. The bearing frame 5810 drives the moving plate 589 to move, and the moving plate 589 slides inside the fixed shell 587. Due to the setting of the second cooler 5811, the second cooler 5811 cools the air inside the fixed shell 587. At this time, the moving plate 589 makes the cold air inside the fixed shell 587 enter the inside of the bent pipe 5812. Due to the setting of the round holes 5813, the cold air jets out through the round holes 5813 at the bent pipe 5812, and the cold air jets on the upper and lower surfaces of the circuit board to cool the circuit board, improving the comprehensiveness of the circuit board cooling.

[0051] A method for using a turning and cooling machine for producing circuit boards includes the following steps:

[0052] Step 1: Perform the turning work on the circuit board. Convey the circuit board in the production process to the top of the conveyor 3. The conveyor 3 drives the circuit board to move between two adjacent turning plates 54. At this time, start the motor 51. The motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the roller 53 to rotate. The roller 53 drives the turning plate 54 to rotate. The turning plate 54 drives the circuit board to rotate, so that the circuit board moves to the top of another conveyor 3.

[0053] Step 2: Cool the circuit board. When the arc-shaped clamping shell 572 clamps the circuit board, due to the reaction force of the circuit board, the circuit board causes the arc-shaped clamping shell 572 to drive the connecting rod 571 to move towards the special-shaped shell 561. The connecting rod 571 drives the sliding plate 562 to move into the special-shaped shell 561. Due to the setting of the first cooler 564, the air flow inside the special-shaped shell 561 is cooled, so that the cold air inside the special-shaped shell 561 enters the inside of the round tube 574. The cold air enters the inside of the arc-shaped clamping shell 572 through the round tube 574, and the cold air jets towards both ends of the circuit board through the air holes 573 at the arc-shaped clamping shell 572;

[0054] Step 3: Improve the clamping stability. When the arc-shaped clamping shell 572 gradually approaches the special-shaped shell 561, the generated extrusion force causes the rotating plate 582 to rotate along the special-shaped shell 561, so that the rotating plate 582 drives the slider 584 to slide along the inner wall of the square groove 583. The slider 584 drives the cross bar 585 to move, and the cross bar 585 drives the extrusion block 586 to move. During the movement of the extrusion block 586, it will come into contact with one end of the circuit board and push the circuit board;

[0055] Step 4: Improve the cooling effect. When the circuit board moves under the extrusion of the extrusion block 586, the circuit board will come into contact with the side surface of the bearing frame 5810 and squeeze the bearing frame 5810. The bearing frame 5810 drives the moving plate 589 to move. The moving plate 589 slides inside the fixed shell 587. Due to the setting of the second cooler 5811, the second cooler 5811 cools the air inside the fixed shell 587. At this time, the moving plate 589 makes the cold air inside the fixed shell 587 enter the inside of the elbow pipe 5812. Due to the setting of the round hole 5813, the cold air jets outwards through the round hole 5813 at the elbow pipe 5812, and the cold air jets on the upper and lower surfaces of the circuit board.

[0056] During use, the circuit board in the production process is conveyed to the top of the conveying member 3. The conveying member 3 drives the circuit board to move between two adjacent turning plates 54. At this time, the motor 51 is started. The motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the roller 53 to rotate. The roller 53 drives the turning plate 54 to rotate. The turning plate 54 drives the circuit board to rotate, so that the circuit board moves to the top of another conveying member 3 for the turning plate operation. Due to the arrangement of the spring 563, the spring 563 drives the sliding plate 562 to move. The sliding plate 562 drives the connecting rod 571 to move. The connecting rod 571 drives the arc-shaped clamping shell 572 to move. The two arc-shaped clamping shells 572 can initially clamp the circuit board. When the rotating shaft 52 rotates, the rotating shaft 52 drives the disc 551 to rotate. The disc 551 drives the belt 552 to rotate. The belt 552 drives the rotating frame 553 to rotate. The rotating frame 553 drives the reciprocating lead screw 554 to rotate. When the disc 551 rotates half a turn, the reciprocating lead screw 554 will drive the threaded platform 555 to perform a reciprocating operation process. The threaded platform 555 drives the special-shaped shell 561 to move. The special-shaped shell 561 drives the sliding plate 562 to move. The sliding plate 562 drives the connecting rod 571 to move. The connecting rod 571 drives the arc-shaped clamping shell 572 to move. The two arc-shaped clamping shells 572 move closer to each other, thereby clamping the circuit board, improving the clamping effect of the arc-shaped clamping shell 572 on the circuit board, and preventing the circuit board from shifting during the turning process. Due to the arrangement of the annular groove 556, the arc-shaped clamping shell 572 drives the block 575 to be located on the inner wall of the card slot 576 at the turning plate 54 for the card position work, enabling the special-shaped shell 561 to rotate inside the annular groove 556, so that the arc-shaped clamping shell 572 is always between two adjacent turning plates 54, improving the clamping stability of the arc-shaped clamping shell 572.

[0057] When the arc-shaped clamping shell 572 clamps the circuit board, due to the reaction force of the circuit board, the circuit board causes the arc-shaped clamping shell 572 to drive the connecting rod 571 to move towards the special-shaped shell 561. The connecting rod 571 drives the sliding plate 562 to move into the interior of the special-shaped shell 561. Due to the arrangement of the first cooler 564, the air flow inside the special-shaped shell 561 is cooled. The cold air inside the special-shaped shell 561 enters the interior of the round tube 574. The cold air enters the interior of the arc-shaped clamping shell 572 through the round tube 574. The cold air jets towards both ends of the circuit board through the air holes 573 at the arc-shaped clamping shell 572, thereby cooling the circuit board. Due to the arc-shaped surface arrangement of the arc-shaped clamping shell 572, the circuit board will gradually move to the center of the arc-shaped surface of the arc-shaped clamping shell 572, facilitating the cold air to jet on the upper and lower surfaces of the circuit board and improving the cooling effect of the device on the circuit board.

[0058] When the arc-shaped housing 572 and the special-shaped housing 561 gradually approach, the generated extrusion force causes the rotating plate 582 to rotate along the special-shaped housing 561, enabling the rotating plate 582 to drive the slider 584 to slide along the inner wall of the square groove 583. The slider 584 drives the cross bar 585 to move, and the cross bar 585 drives the extrusion block 586 to move. During the movement of the extrusion block 586, it will come into contact with one end of the circuit board and push the circuit board, preventing the circuit board from slipping during the turning process and improving the stability of the circuit board turning.

[0059] When the circuit board is pushed to move by the extrusion block 586, the circuit board will come into contact with the side surface of the carrier 5810 and squeeze the carrier 5810. The carrier 5810 drives the moving plate 589 to move, and the moving plate 589 slides inside the fixed housing 587. Due to the arrangement of the second cooler 5811, the second cooler 5811 cools the air inside the fixed housing 587. At this time, the moving plate 589 allows the cold air inside the fixed housing 587 to enter the inside of the elbow pipe 5812. Due to the arrangement of the round hole 5813, the cold air jets outwards through the round hole 5813 at the elbow pipe 5812, and the cold air jets on the upper and lower surfaces of the circuit board to cool the circuit board, improving the comprehensiveness of the circuit board cooling and enhancing the cooling effect of the device on the circuit board.

A method for using a plate turning cooling machine for producing circuit boards, using the plate turning cooling machine for producing circuit boards as claimed in claim 9, characterized in that : It includes the following steps: Step 1: Turn over the circuit board, convey the circuit board in the production process to the top of the conveying member (3), the conveying member (3) drives the circuit board to move between two adjacent turning plates (54), then start the motor (51), the motor (51) drives the rotating shaft (52) to rotate, the rotating shaft (52) drives the roller (53) to rotate, the roller (53) drives the turning plate (54) to rotate, the turning plate (54) drives the circuit board to rotate, so that the circuit board moves to the top of another conveying member (3); Step 2: Cooling the circuit board. When the arc-shaped clamping shell (572) clamps the circuit board, it is subjected to the reaction force of the circuit board. The circuit board causes the arc-shaped clamping shell (572) to drive the connecting rod (571) to move toward the special-shaped shell (561). The connecting rod (571) drives the sliding plate (562) to move toward the inside of the special-shaped shell (561). The first cooler (564) is set to cool the air flow inside the special-shaped shell (561). The cold air inside the special-shaped shell (561) enters the inside of the circular tube (574). The cold air enters the inside of the arc-shaped clamping shell (572) through the circular tube (574). The cold air is sprayed toward both ends of the circuit board through the air holes (573) at the arc-shaped clamping shell (572). Step 3: Improving the clamping stability. When the arc-shaped clamping shell (572) and the special-shaped shell (561) gradually approach each other, the generated extrusion force causes the rotating plate (582) to rotate along the special-shaped shell (561), so that the rotating plate (582) drives the slider (584) to slide along the inner wall of the square groove (583), and the slider (584) drives the cross bar (585) to move. The cross bar (585) drives the extrusion block (586) to move. During the movement of the extrusion block (586), it will come into contact with one end of the circuit board to push the circuit board; Step 4: The cooling effect is improved. When the circuit board is squeezed and moved by the squeezing block (586), the circuit board will contact the side of the support frame (5810) and squeeze the support frame (5810). The support frame (5810) drives the movable plate (589) to move. The movable plate (589) slides inside the fixed shell (587) and is affected by the setting of the second cooler (5811). The second cooler (5811) cools down the internal air of the fixed shell (587). At this time, the movable plate (589) allows the cold air inside the fixed shell (587) to enter the inside of the bent pipe (5812).
