Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board production equipment, and particularly relates to a cooling device for circuit board production. Background Art

[0002] With the rapid development of electronic technology, electronic components on circuit boards are becoming increasingly dense, and power density is also increasing. This causes circuit boards to generate a large amount of heat immediately after production. If this heat cannot be dissipated in a timely manner, the board's temperature will rise sharply, affecting its performance, reliability, and lifespan. Therefore, effective cooling measures are particularly important during the circuit board production process.

[0003] However, in the current circuit board cooling process, since the completed circuit boards are basically transported in a flat state, in order to allow them to cool completely, a sufficiently long production line is required for the circuit boards to pass through and be air-cooled. An overly long production line set up for cooling will take up too much space in the workshop. Production space itself is at a premium, and using a large amount of space just to achieve the cooling effect of the circuit boards will result in a very low production efficiency. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a cooling device for circuit board production. The circuit board is arranged vertically, and after losing the support of the straightening seat during the transmission of the circuit board, it is tilted in the clamping seat. The wind from the cooling fan can accelerate the wind speed when passing between the circuit boards and take away the heat on the circuit board in time, which can reduce the occupied space while ensuring cooling.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The transmission mechanism is connected to the transmission mechanism by a pair of rotating shafts, and the rotating shafts are connected to the transmission mechanism by a pair of rotating shafts, and the rotating shafts are connected to the transmission mechanism by a pair of rotating shafts.

[0007] The cross-section of the clamping seat is a U-shaped structure formed by connecting a support plate, a bottom plate and an abutment plate in sequence, and an extension plate extending toward the support plate is provided on the upper end of the abutment plate; the straightening seat is a plate-shaped structure extending upward, and in the projection direction of the straightening seat toward the clamping seat, the straightening seat is located between the support plate and the extension plate; the clamping seat and the straightening seat include several groups, several groups of the clamping seats are parallel to each other and evenly distributed on the outer surface of the conveyor belt, and several groups of the straightening seats are parallel to each other and evenly distributed on the outer wall of the straightening belt.

[0008] The cooling device for circuit board production adopts this structure, the conveying assembly is the main conveying device for the circuit board, and the straightening assembly is the auxiliary abutment device for the circuit board. The driven conveying roller on the conveying assembly and the driven straightening roller on the straightening assembly are coaxially connected. Under the drive of the motor, the driven conveying roller and the driven straightening roller rotate simultaneously. The length of the conveyor belt is longer than the straightening belt. Several evenly distributed and mutually parallel clamping seats on the conveyor belt and several evenly distributed and mutually parallel straightening seats on the straightening belt overlap with each other on the projection surface. The straightening seat is located between the support plate and the extension plate on the clamping seat. Therefore, when the circuit board is inserted from top to bottom into the U-shaped structure of the clamping seat, one end face of the circuit board will abut on the extension plate, and the other end face of the circuit board will abut on the straightening seat. That is, through the staggered setting of the clamping seat and the straightening seat, the circuit board is clamped and kept in a vertical state. During the driving process of the motor, the circuit board clamped by the clamping seat and the straightening seat will move toward the direction of the driven conveying roller. Since the straightening belt is short, when the circuit board moves to the position of the driven straightening roller, as the straightening seat As the circuit board gradually moves downward along the rotation direction of the driven straightening roller, the circuit board will lose the abutment of the straightening seat, causing the upper end of the circuit board to tilt in the forward direction. Due to the setting of the extension plate on the clamping seat, the circuit board will be stuck between the extension plate and the support plate, maintaining the inclined state of the circuit board. At this time, the circuit board has left the position of the driven straightening roller and entered the area where the cooling fan is located. The wind blown upward by the cooling fan will enter between the circuit boards that are tilted to each other. Therefore, the air duct will first hit the circuit board and then change direction to enter the gap between the circuit boards. Since the circuit board is tilted and the gap has changed, the air duct here will accelerate the flow due to the smaller gap, and the position blowing over the inclined surface of the circuit board can also accelerate the temperature removal on the circuit board. Therefore, only a smaller area is needed to achieve the passage and cooling of multiple groups of circuit boards, so that the space occupied by this position can be greatly compressed. After cooling, the circuit board continues to move forward to the area of the driven conveyor roller, and the gradually horizontal circuit board will fall onto the discharge belt, be taken away by the discharge belt, and enter the next process.

[0009] Furthermore, the conveying assembly includes two groups, the straightening assembly and the cooling fan are both arranged between the two groups of conveying assemblies, and the cooling fan is arranged between the driven conveying roller and the driven straightening roller.

[0010] Compared with the prior art, the advantages of the present invention are: the circuit boards that are vertically distributed in sequence are first clamped by the staggered clamping seats and the straightening seats and transported forward until the rotating straightening seats are separated from the abutment against the circuit boards, so that several groups of circuit boards are in an inclined state, and the wind blown by the cooling fan will first hit the circuit boards and then change direction to enter the gaps between the circuit boards. Since the circuit boards are tilted and the gaps have changed, the air duct here will accelerate the flow due to the smaller gaps, and the position of blowing over the inclined surface of the circuit boards can also accelerate the removal of temperature on the circuit boards. This structure can compress the space occupied by the device to the greatest extent, and can also achieve a good cooling effect on the circuit boards. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The cross-section of the clamping seat 24 is a U-shaped structure formed by connecting a support plate 241, a bottom plate 242 and an abutment plate 243 in sequence, and an extension plate 244 extending toward the support plate 241 is provided on the upper end of the abutment plate 243; the straightening seat 34 is a plate-shaped structure extending upward, and in the projection direction of the straightening seat 34 toward the clamping seat 24, the straightening seat 34 is located between the support plate 241 and the extension plate 244; the clamping seat 24 and the straightening seat 34 include several groups, several groups of the clamping seats 24 are parallel to each other and evenly distributed on the outer surface of the conveyor belt 23, and several groups of the straightening seats 34 are parallel to each other and evenly distributed on the outer wall of the straightening belt 33.

[0020] Furthermore, the conveying assembly 2 includes two groups, the straightening assembly 3 and the cooling fan 4 are both arranged between the two groups of conveying assemblies 2, and the cooling fan 4 is arranged between the driven conveying roller 22 and the driven straightening roller 32.

[0021] Description of the working method of this utility model:

[0022] In the cooling device for circuit board production using this structure, the conveying assembly 2 is the main conveying device for the circuit board 6, and the straightening assembly 3 is the auxiliary contact device for the circuit board 6. The driving conveying roller 21 on the conveying assembly 2 and the driving straightening roller 31 on the straightening assembly 3 are coaxially connected. Driven by the motor 25, the conveying roller 21 and the driving straightening roller 31 rotate simultaneously. The length of the conveyor belt 23 is longer than the straightening belt 33. Several evenly distributed and mutually parallel clamping seats 24 on the conveyor belt 23 and several evenly distributed and mutually parallel straightening seats 34 on the straightening belt 33 overlap with each other on the projection surface. The straightening seats 34 are located at the clamping position. The support plate 241 and the extension plate 244 on the receiving seat 24 are arranged between them. Therefore, when the circuit board 6 is inserted into the U-shaped structure of the receiving seat 24 from top to bottom, one end surface of the circuit board 6 will abut against the extension plate 244, and the other end surface of the circuit board 6 will abut against the straightening seat 34. That is, the circuit board 6 is clamped and kept in a vertical state by the staggered setting of the receiving seat 24 and the straightening seat 34. During the driving process of the motor 25, the circuit board 6 clamped by the receiving seat 24 and the straightening seat 34 will move toward the direction of the driven conveying roller 22. Since the straightening belt 33 is short, when the circuit board 6 moves to the driven straightening roller 22, the straightening belt 33 will move toward the driven straightening roller 22. When the positive roller 32 is in the position, as the straightening seat 34 gradually moves downward along the rotation direction of the driven straightening roller 32, the circuit board 6 will lose the abutment of the straightening seat 34, causing the upper end of the circuit board 6 to tilt in the forward direction. Due to the setting of the extension plate 244 on the clamping seat 24, the circuit board 6 will be stuck between the extension plate 244 and the support plate 241, maintaining the inclined state of the circuit board 6. At this time, the circuit board 6 is out of the position of the driven straightening roller 32 and enters the area where the cooling fan 4 is located. The wind blown upward by the cooling fan 4 will enter between the circuit boards 6 that are tilted to each other, so the air duct will first hit the circuit board 6. After the board 6 changes direction, it enters the gap between the circuit boards 6. Since the circuit boards 6 are tilted and the gap has changed, the air duct here will accelerate the flow due to the smaller gap, and the air blowing over the inclined surface of the circuit boards 6 can also accelerate the temperature removal on the circuit boards 6. Therefore, only a smaller area is needed to enable multiple groups of circuit boards 6 to pass through and be cooled, so that the space occupied by this position can be greatly compressed. After cooling, the circuit boards 6 continue to move forward to the area of the driven conveyor roller 22, and the gradually horizontal circuit boards 6 will fall onto the discharge belt 5, be taken away by the discharge belt 5, and enter the next process.

[0023] Two groups of conveying components 2 are set, and the straightening components 3 and the cooling fan 4 are both set between the two groups of conveying components 2. Therefore, when the circuit board 6 is abutted and clamped by the clamping seat 24 and the straightening seat 34, it can have a three-sided clamping state, so that the circuit board 6 can maintain a more stable state for conveyance. After breaking away from the abutment of the straightening seat 34, the circuit board 6 still has two groups of clamping seats 24 to stabilize it. The cooling fan 4 is set between the driven conveying roller 22 and the driven straightening roller 32, which can realize rapid cooling of the circuit board 6 in the tilted position.

[0024] The beneficial effect of the present invention is that the circuit boards 6 that are vertically distributed in sequence are first clamped by the staggered clamping seats 24 and the straightening seats 34 and transported forward until the rotating straightening seats 34 are separated from the abutment against the circuit boards 6, so that the groups of circuit boards 6 are in an inclined state, and the wind blown by the cooling fan 4 will first hit the circuit boards 6 and then change direction to enter the gaps between the circuit boards 6. Since the circuit boards 6 are tilted and the gaps have changed, the air duct here will accelerate the flow due to the smaller gaps, and the air blowing over the inclined surface of the circuit boards 6 can also accelerate the removal of temperature from the circuit boards 6. This structure can compress the space occupied by the device to the greatest extent, and can also achieve a good cooling effect on the circuit boards 6.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.

However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
