During the cooling process of the circuit board, a cooling plate rack is needed to place the circuit board.

[0003] A Chinese patent with authorization announcement number CN 219686307 U discloses a cooling board frame for circuit board production, including a base and a rotating sleeve, a rotating sleeve is provided on the top of the base, a main heat dissipation pipe is provided inside the rotating sleeve, a connecting pipe is provided inside the main heat dissipation pipe, an air guide shell is provided at one end of the connecting pipe, an L-shaped plug board is provided at one end of the air guide shell, a slot is provided on the L-shaped plug board, a heat dissipation hole is provided on the side of the L-shaped plug board close to the air guide shell, and a fan is provided on the top of the main heat dissipation pipe. When cooling and dissipating heat, the utility model starts the fan to blow air into the main heat dissipation pipe, guides the connecting pipe and the air guide shell, so that the outside air is blown out through the heat dissipation holes to blow and dissipate heat between the circuit boards, and the multi-layer design of the connecting pipe on the main heat dissipation pipe allows the wind at the top to reach the bottom, which is convenient for uniform heat dissipation of the circuit board and ensures the cooling efficiency.

[0004] In the process of placing the circuit board on the existing cooling board rack, since the cooling board rack is a fixed structure, it is troublesome to place the circuit board at a high place, resulting in poor placement convenience; therefore, a cooling board rack for circuit board production is proposed to solve the above problem. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve the problems existing in the prior art, the utility model provides a cooling plate rack for circuit board production.

[0006] The technical solution adopted by the present utility model to solve its technical problems is as follows: A cooling plate rack for circuit board production according to the present utility model includes a base, on which a rotating frame is rotatably installed. A stepping motor is installed on the top plate of the rotating frame through a machine base. A winding roller is installed on the output shaft of the stepping motor. Two fixing plates are symmetrically installed on the top plate of the rotating frame. The winding roller is rotatably installed between the two fixing plates. A steel wire is wound around the winding roller. A pipe hole is opened on the top plate of the rotating frame, and a conduit is fixedly installed in the pipe hole. The steel wire passes through the conduit. A first fixing block is fixedly sleeved on the steel wire. Four first guiding plates are installed on the first fixing block. Multiple groups of exhaust grooves are opened on the side wall of the rotating frame. The first guiding plates are assembled in the exhaust grooves. A positioning plate is welded to the bottom side of the first guiding plate, and the positioning plate is fixedly connected to the inner wall of the rotating frame. A number of second fixing blocks are fixedly sleeved on the steel wire. Four second guiding plates are installed on the second fixing blocks. The second guiding plates are assembled in the exhaust grooves. A first placing plate is installed on the outer wall of the first guiding plate, and a second placing plate is installed on the outer wall of the second guiding plate. The first placing plate and the second placing plate are of annular structures. The first placing plate and the second placing plate are sleeved around the rotating frame. A number of groups of clamping blocks are installed on the first placing plate and the second placing plate. Circuit boards are placed on the clamping blocks. The included angle between two adjacent first guiding plates is 90°, the included angle between two adjacent second guiding plates is 90°, and the included angle between two adjacent exhaust grooves is 30°. A connecting groove is opened in the base, and a connecting ring is assembled in the connecting groove. The connecting ring is fixedly connected to the rotating frame. By operating the stepping motor, the winding roller is driven to rotate, and the winding roller winds the steel wire. The steel wire moves vertically upward until the steel wire in the rotating frame is straightened. At this time, the first second placing plate is at the highest position. In this structure, a number of second placing plates rise only after the circuit boards are placed, avoiding the operator from placing the circuit boards at a high place, which is beneficial to improving the convenience of placement.

A plurality of air outlet holes are opened on the top plate of the base, and the included angle between two adjacent air outlet holes is 30°. Since each group of clamping blocks on the first placing plate and the second placing plate corresponds to the exhaust grooves, cold air is introduced into the air inlet pipe. The cold air enters the cavity, and then is discharged into the interior of the rotating frame from a number of air outlet holes, and finally discharged from a number of exhaust grooves to cool the circuit boards, which is beneficial to improving the cooling effect on the circuit boards.

[0008] The advantages of the present utility model are as follows:

[0009] 1. The utility model operates through a stepping motor to drive the winding roller to rotate. The winding roller winds the steel wire, and the steel wire moves vertically upward until the steel wire in the rotating frame is straightened. At this time, the first second placement plate is at the highest position. In this structure, several second placement plates rise only after placing the circuit board, avoiding the operator from placing the circuit board at a high place, which is beneficial to improving the convenience of placement.

[0010] 2. In the utility model, each group of clamping blocks on the first placement plate and the second placement plate corresponds to the exhaust grooves. Cold air is introduced into the air inlet pipe, enters the cavity, then is discharged into the inside of the rotating frame from several air outlet holes, and finally is discharged from several exhaust grooves to cool the circuit board, which is beneficial to improving the cooling effect on the circuit board.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Please refer to Figures 1-4As shown in the figure, a cooling plate rack for circuit board production includes a base 1. A rotating frame 2 is rotatably installed on the base 1. A stepping motor 3 is installed on the top plate of the rotating frame 2 through a machine base. A winding roller 4 is installed on the output shaft of the stepping motor 3. Two fixing plates 5 are symmetrically installed on the top plate of the rotating frame 2. The winding roller 4 is rotatably installed between the two fixing plates 5. A steel wire 6 is wound around the winding roller 4. A pipe hole is opened on the top plate of the rotating frame 2, and a conduit 7 is fixedly installed in the pipe hole. The steel wire 6 passes through the conduit 7. A first fixing block 8 is fixedly sleeved on the steel wire 6. Four first guiding plates 9 are installed on the first fixing block 8. A plurality of exhaust grooves 10 are opened on the side wall of the rotating frame 2. The first guiding plates 9 are assembled in the exhaust grooves 10. A positioning plate 11 is welded to the bottom side of the first guiding plate 9, and the positioning plate 11 is fixedly connected to the inner wall of the rotating frame 2. A number of second fixing blocks 12 are fixedly sleeved on the steel wire 6. Four second guiding plates 13 are installed on the second fixing blocks 12. The second guiding plates 13 are assembled in the exhaust grooves 10. A first placing plate 14 is installed on the outer wall of the first guiding plate 9, and a second placing plate 15 is installed on the outer wall of the second guiding plate 13. The first placing plate 14 and the second placing plate 15 are of annular structure. The first placing plate 14 and the second placing plate 15 are sleeved around the rotating frame 2. A number of groups of clamping blocks 21 are installed on the first placing plate 14 and the second placing plate 15. Circuit boards 22 are placed on the clamping blocks 21. The included angle between two adjacent first guiding plates 9 is 90°. The included angle between two adjacent second guiding plates 13 is 90°. The included angle between two adjacent exhaust grooves 10 is 30°. A connection groove 16 is opened in the base 1, and a connection ring 17 is assembled in the connection groove 16. The connection ring 17 is fixedly connected to the rotating frame 2;During operation, when the existing cooling plate rack places the circuit board 22, since the cooling plate rack is a fixed structure, it is rather troublesome to place the circuit board 22 at a high position, resulting in poor placement convenience. By loosening and releasing the steel wire 6 through the winding roller 4, all the second placement plates 15 are stacked on the bottommost first placement plate 14. The uppermost second placement plate 15 is the first second placement plate 15. At this time, the position of the uppermost first second placement plate 15 is at the middle of the rotating frame 2. Place the circuit board 22 on the clamping block 21 of the first second placement plate 15. During the placement process, the rotating frame 2 can rotate on the base 1, realizing the convenient placement of the circuit board 22 on the first second placement plate 15. After the placement of the first second placement plate 15 is completed, the stepping motor 3 operates to drive the winding roller 4 to rotate. The winding roller 4 winds the steel wire 6. The steel wire 6 moves vertically upward. The steel wire 6 drives the uppermost first second fixing block 12 to move vertically upward. The first second fixing block 12 drives the first second guide plate 13 to move vertically upward. The first second guide plate 13 drives the first second placement plate 15 to move vertically upward. After the first second placement plate 15 moves upward a certain distance, there is a space between the first second placement plate 15 and the second second placement plate 15 below it. Then place the circuit board 22 on the second second placement plate 15. After the placement is completed, the stepping motor 3 continues to operate. The steel wire 6 drives the first second placement plate 15 and the second second placement plate 15 to move upward simultaneously. Then continue to place the circuit board 22 on the third second placement plate 15 until the steel wire 6 in the rotating frame 2 is straightened. At this time, the first second placement plate 15 is at the highest position, while the bottommost first placement plate 14 remains fixed. The several second placement plates 15 in this structure rise only after the circuit board 22 is placed, avoiding the operator from placing the circuit board 22 at a high position, which is beneficial to improving the placement convenience.

[0020] Please refer to Figure 5 As shown in the figure, a cavity 18 is opened inside the base 1. An air inlet pipe 19 is installed on the side wall of the base 1. The air inlet pipe 19 extends into the cavity 18. A plurality of air outlet holes 20 are opened on the top plate of the base 1. The included angle between two adjacent air outlet holes 20 is 30°. During operation, when the existing cooling plate rack places the circuit board 22, it is unable to quickly cool the circuit board 22, resulting in poor cooling effect on the circuit board 22. By placing the just-produced circuit board 22 with a higher temperature on the clamping blocks 21 of the first placement plate 14 and the second placement plate 15, each group of clamping blocks 21 on the first placement plate 14 and the second placement plate 15 corresponds to the exhaust grooves 10. Cold air is introduced into the air inlet pipe 19. The cold air enters the cavity 18, and then is discharged into the inside of the rotating frame 2 from a plurality of air outlet holes 20, and finally discharged from a plurality of exhaust grooves 10 to cool the circuit board 22, which is beneficial to improving the cooling effect on the circuit board 22.

[0021] Working principle: During the process of placing the circuit board 22 on the existing cooling plate rack, since the cooling plate rack is a fixed structure, it is rather troublesome to place the circuit board 22 at a high position, resulting in poor placement convenience. By loosening and releasing the steel wire 6 through the winding roller 4, all the second placement plates 15 are stacked on the bottommost first placement plate 14. The uppermost second placement plate 15 is the first second placement plate 15. At this time, the position of the uppermost first second placement plate 15 is at the middle of the rotating frame 2. Place the circuit board 22 on the clamping block 21 of the first second placement plate 15. During the placement process, the rotating frame 2 can rotate on the base 1, realizing the convenient placement of the circuit board 22 on the first second placement plate 15. After the placement of the first second placement plate 15 is completed, the stepping motor 3 operates to drive the winding roller 4 to rotate. The winding roller 4 winds the steel wire 6, and the steel wire 6 moves vertically upward. The steel wire 6 drives the uppermost first second fixing block 12 to move vertically upward. The first second fixing block 12 drives the first second guide plate 13 to move vertically upward. The first second guide plate 13 drives the first second placement plate 15 to move vertically upward. After the first second placement plate 15 moves upward a certain distance, there is a space between the first second placement plate 15 and the second second placement plate 15 below it. Then place the circuit board 22 on the second second placement plate 15. After the placement is completed, the stepping motor 3 continues to operate, and the steel wire 6 drives the first second placement plate 15 and the second second placement plate 15 to move upward simultaneously. Then continue to place the circuit board 22 on the third second placement plate 15 until the steel wire 6 in the rotating frame 2 is straightened. At this time, the first second placement plate 15 is at the highest position, while the bottommost first placement plate 14 remains fixed. In this structure, several second placement plates 15 rise only after the circuit board 22 is placed, avoiding the operator from placing the circuit board 22 at a high position, which is beneficial to improving the placement convenience. During the process of placing the circuit board 22 on the existing cooling plate rack, the circuit board 22 cannot be quickly cooled, resulting in poor cooling effect on the circuit board 22. By placing the newly produced circuit board 22 with a high temperature on the clamping block 21 of the first placement plate 14 and the second placement plate 15, each group of clamping blocks 21 on the first placement plate 14 and the second placement plate 15 corresponds to the exhaust grooves 10. Cold air is introduced into the air inlet pipe 19. The cold air enters the cavity 18 and then is discharged into the interior of the rotating frame 2 through several air outlet holes 20 and finally discharged from several exhaust grooves 10 to cool the circuit board 22, which is beneficial to improving the cooling effect on the circuit board 22.
