Description

Technical Field

[0001] The invention belongs to the relevant field of PCB board processing technology, and more specifically to a PCB board tin-spraying floating bed with continuous flip plate cooling. Background Art

[0002] After tin spraying, the surface temperature of the PCB board is relatively high, so it needs to be cooled. At present, the PCB board after tin spraying is usually placed on a floating bed, and an air flow will be blown out from the floating bed at an angle upwards, blowing the PCB board along the length direction of the floating bed, thereby cooling the PCB board after tin spraying.

[0003] The patent document with announcement number CN205566832U records a gas floating bed for PCB board tin spraying treatment, including a floating bed body, an inclined plate, a control system, a first sensor, a second sensor, a first baffle mechanism and a second baffle mechanism. The inclined plate connects the front and rear ends of the floating bed body, and the inclined plate is provided with a plate placing section, a stop section and a plate exit section in sequence. The front end of the plate placing section is a plate placing port, and the end of the plate exit section is a plate exit. The first sensor is located above the plate placing port and is fixedly connected to both sides of the floating bed body. Slide rails are provided on both sides of the floating bed body, and both ends of the second sensor are slidably connected to the slide rails. The first baffle mechanism is located below the connection between the plate placing section and the stop section, and the second baffle mechanism is located below the connection between the stop section and the plate exit section. It is easy to use and has strong applicability. It can meet the cooling treatment of large quantities of tin spraying plates after tin spraying, and has high work efficiency.

[0004] The above-mentioned device has certain shortcomings when performing the cooling operation of the PCB board. The PCB board after the tin spraying treatment is cooled by moving by adopting a floating bed structure. In order to ensure the cooling effect, the floating bed structure needs to increase the length of the floating bed to make the PCB board contact with the airflow for a longer time, so that the PCB board can achieve the effect of complete cooling. However, the method of increasing the length of the floating bed structure increases the overall volume of the floating bed, resulting in a larger area occupied by the floating bed, making it impossible to complete the cooling operation of the PCB board in a limited space. Summary of the invention

[0005] The purpose of the present invention is to provide a PCB board tin-spraying floating bed with continuous flap cooling, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. After the tin-spraying treatment, the PCB board body is cooled by moving through the floating bed structure. In order to ensure the cooling effect, the floating bed structure needs to increase the length of the floating bed to make the PCB board body contact with the airflow for a longer time, so that the PCB board body can achieve the effect of complete cooling. However, increasing the length of the floating bed structure increases the overall volume of the floating bed, resulting in a larger area occupied by the floating bed, making it impossible to complete the cooling operation of the PCB board body in a limited space:

[0008] A PCB tin-spraying floating bed with continuous flip plate cooling comprises a fixed base, a first rotating part and a second rotating part, wherein the first rotating part and the second rotating part are both movably mounted on the inner side of the upper end of the fixed base, the first rotating part is located on one side of the second rotating part, a central rotating frame is obliquely arranged between the first rotating part and the second rotating part, the first rotating part and the second rotating part both comprise a rotating drum and a plurality of groups of shift rods for supporting a PCB body, the plurality of groups of shift rods are distributed in a ring shape on the outer surface of the rotating drum, and the plurality of groups of shift rods are arranged side by side, a side of the fixed base is provided with a side cyclone fan for use with the first rotating part and the second rotating part, and the fixed base and the side cyclone fan are movably connected via a fan frame.

[0009] As a further technical solution of the present invention, a rotating rod is installed at the middle position of the inner side of the rotating drum, one end of the rotating rod is driven by a motor and a gear, and the interior of the rotating drum is a hollow structure. During operation, the gear is driven by the motor so that the gear drives the rotating rod, and the rotating drum is driven to rotate by the rotating rod, so that the several groups of gear rods of the first rotating part and the second rotating part are kept in a rotating state, and the PCB board body after the tin spraying treatment is conveyed by the conveyor belt so that the PCB board body is placed on the upper part of the feeding bracket. When the first rotating part rotates, the several groups of gear rods pass through the feeding bracket so that the several groups of gear rods contact the bottom of the PCB board body. During the rotation of the several groups of gear rods, the PCB board body is stuck between the several groups of gear rods, and the rotation of the several groups of gear rods drives the PCB board body to rotate 180 degrees. When the PCB board body rotates, the side cyclone fan is used to cool the PCB board body. The rotating structure of the first rotating part and the second rotating part can realize the rotation operation of the PCB board body, so that the PCB board body can fully dissipate heat and cool down within a short distance.

[0010] As a further technical solution of the present invention, a plurality of groups of support rods are arranged side by side on both sides of the transfer rack, and the two ends of the transfer rack and the fixed base are docked and fixed by inclined clamps. The inclined transfer rack can be used to cooperate with a plurality of groups of support rods to transfer the PCB board from the first rotating part to the second rotating part, and the transfer operation of the PCB board is completed, and the second rotating part can effectively extend the cooling time of the PCB board. During operation, when the PCB board rotates to one hundred and eighty degrees under the action of the rotating drum, the support rod on one side of the transfer rack will contact the surface of the PCB board, so that the PCB board slides along the inclined transfer rack, and slides from the support rod on one side of the transfer rack to the support rod on the other side. When the second rotating part is in operation, the gear rod passes through the plurality of groups of support rods, so that the PCB board is placed on the gear rod of the second rotating part, and the rotation transfer operation is completed.

[0011] As a further technical solution of the present invention, several groups of feeding brackets are installed on the inner side of one end of the fixed base, and several groups of receiving brackets are installed on the inner side of the other end of the fixed base. The several groups of feeding brackets and the several groups of receiving brackets are arranged side by side. The arrangement of the feeding brackets and the receiving brackets can facilitate the loading and discharging operations of the PCB board. During loading, the gear lever passes through the receiving bracket to complete the PCB board taking operation. During the receiving operation, when the PCB board rotates to the receiving bracket, the first rotating part and the second rotating part pause for a few seconds, so that the PCB board on the first rotating part can slide and transfer on the intermediate transfer rack, and at the same time, the PCB board on the second rotating part falls into the receiving bracket, and is discharged downward by the inclined receiving bracket to avoid affecting the rotation of the second rotating part.

[0012] As a further technical solution of the present invention, guide wheels are provided on the surfaces of the feeding bracket, the receiving bracket and the support rod. The receiving bracket is arranged at an angle, and one end of the receiving bracket and the fixed base are connected by a fixed substrate. Both ends of the fixed substrate are fixedly installed with docking strips. By utilizing the upper setting of the guide wheels, the friction of the feeding bracket, the receiving bracket and the support rod can be reduced to avoid surface wear on the PCB board body. The inclined receiving bracket facilitates the discharge operation of the PCB board body.

[0013] As a further technical solution of the present invention, a bearing is installed at the middle position of the lower end of the side cyclone fan, and a turntable is installed at the middle position of the upper end of the side cyclone fan. In order to improve the air-cooling and heat dissipation effect of the PCB board, the straight-blowing fan structure is adjusted to an oblique-blowing fan structure. By rotating the turntable and adjusting the side cyclone fan by using the setting of the bearing, the side cyclone fan is formed as follows: Figure 7 As shown in , the PCB body is subjected to oblique air cooling so that the airflow is in full contact with the surface of the PCB body, thereby improving the heat dissipation effect of the PCB body.

[0014] As a further technical solution of the present invention, a turning groove for cooperating with the side cyclone fan is provided on the inner side of the fan frame, and the interior of the fixed base is a hollow structure. The use angle of the side cyclone fan can be appropriately adjusted by setting the turning groove.

[0015] As a further technical solution of the present invention, the rotating drum and the gear lever are elastically connected by an elastic sleeve, and a rotating sleeve rod is fixedly installed on the outer surface of the rotating rod. In order to adapt to the use of PCB boards of different sizes, the length of the gear lever can be telescopically adjusted by using the elastic sleeve, and the rotating sleeve rod is the main component for controlling several groups of gear levers.

[0016] As a further technical solution of the present invention, a beveled end cap is provided on the outer surface of one end of the gear rod, and a plurality of groups of beveled top caps are installed in a ring shape on the outer surface of the rotating sleeve rod. When the rotating sleeve rod rotates, the beveled top caps and the beveled end caps abut against each other, and one end of the gear rod is pushed by the beveled top caps, thereby adjusting the usable length of the gear rod.

[0017] As a further technical solution of the present invention, the rotating drum and the rotating sleeve rod are connected and fixed by a telescopic plug rod. The outer surface of the rotating sleeve rod is provided with a slot for matching with the telescopic plug rod. The telescopic plug rod can be used to assist in fixing the rotating drum and the rotating sleeve rod. During the adjustment operation, the telescopic plug rod is pulled out so that the rotating sleeve rod can rotate in the rotating drum.

The PCB board body after the tin spraying treatment is conveyed by the conveyor belt, so that the PCB board body is placed on the upper part of the feeding bracket. When the first rotating part rotates, the several groups of gear rods pass through the feeding bracket, so that the several groups of gear rods are in contact with the bottom of the PCB board body. During the rotation of the several groups of gear rods, the PCB board body is stuck between the several groups of gear rods, and the rotation of the several groups of gear rods drives the PCB board body to rotate 180 degrees.

During operation, when the PCB board rotates to 180 degrees under the action of the rotating drum, the support rod on one side of the transfer rack will contact the surface of the PCB board, so that the PCB board slides along the inclined transfer rack, from the support rod on one side of the transfer rack to the support rod on the other side. When the second rotating part is in operation, the gear rod passes through a plurality of groups of support rods, so that the PCB board is placed on the gear rod of the second rotating part, thereby completing the rotation transfer operation;

During loading, the gear lever passes through the receiving bracket to complete the PCB board picking operation. During the receiving operation, when the PCB board rotates to the receiving bracket, the first rotating part and the second rotating part pause for a few seconds, so that the PCB board on the first rotating part can slide and transfer on the transfer rack, and at the same time, the PCB board on the second rotating part falls into the receiving bracket, and is discharged downward by the inclined receiving bracket to avoid affecting the rotation of the second rotating part.

[0037] like Figure 1As shown, a PCB board tin-spraying floating bed with continuous flip plate cooling includes a fixed base 1, a first rotating part 3 and a second rotating part 5. The first rotating part 3 and the second rotating part 5 are both movably mounted on the inner side of the upper end of the fixed base 1, and the first rotating part 3 is located on one side of the second rotating part 5. A middle rotating frame 4 is obliquely arranged between the first rotating part 3 and the second rotating part 5. The first rotating part 3 and the second rotating part 5 both include a rotating drum 14 and a plurality of groups of shift rods 13 for supporting a PCB board body 8. The plurality of groups of shift rods 13 are distributed in a ring shape on the outer surface of the rotating drum 14, and the plurality of groups of shift rods 13 are arranged side by side. A side of the fixed base 1 is provided with a side cyclone 9 for cooperating with the first rotating part 3 and the second rotating part 5, and the fixed base 1 and the side cyclone 9 are movably connected through a fan frame 10.

[0038] To solve the short-distance heat dissipation problem of PCB boards, such as Figure 2 As shown, a rotating rod 15 is installed at the inner middle position of the rotating drum 14, and one end of the rotating rod 15 is driven by the motor 11 and the gear 12. The interior of the rotating drum 14 is a hollow structure. During operation, the motor 11 drives the gear 12, so that the gear 12 drives the rotating rod 15, and the rotating drum 14 is driven to rotate by the rotating rod 15, so that the several groups of gear levers 13 of the first rotating part 3 and the second rotating part 5 are kept in a rotating state, and the conveyor belt 7 is used to convey the PCB board 8 after the tin spraying treatment, so that the PCB board 8 is placed on the upper part of the feeding bracket 6. When the first rotating part 3 rotates, A plurality of groups of gear rods 13 pass through the feed bracket 6, so that the plurality of groups of gear rods 13 are in contact with the bottom of the PCB board 8. During the rotation of the plurality of groups of gear rods 13, the PCB board 8 is clamped between the plurality of groups of gear rods 13. The rotation of the plurality of groups of gear rods 13 drives the PCB board 8 to rotate 180 degrees. When the PCB board 8 rotates, the side cyclone fan 9 is used to cool the PCB board 8. The rotating structure of the first rotating part 3 and the second rotating part 5 can realize the rotation operation of the PCB board 8, so that the PCB board 8 can fully dissipate heat and cool down within a short distance.

[0039] To solve the transfer problem of PCB board during rotation, such as Figure 3As shown, a plurality of groups of support rods 17 are arranged side by side on both sides of the transfer frame 4, and the two ends of the transfer frame 4 and the fixed base 1 are docked and fixed by inclined clamps 18. The inclined transfer frame 4 can cooperate with the plurality of groups of support rods 17 to transfer the PCB board 8 from the first rotating part 3 to the second rotating part 5, and the transfer operation of the PCB board 8 is completed, and the second rotating part 5 can effectively prolong the cooling time of the PCB board 8. During operation, when the PCB board 8 rotates to one hundred and eighty degrees under the action of the rotating drum 14, the support rods 17 on one side of the transfer frame 4 will contact with the surface of the PCB board 8, so that the PCB board 8 slides along the inclined transfer frame 4, and slides from the support rods 17 on one side of the transfer frame 4 to the support rods 17 on the other side. When the second rotating part 5 is in operation, the gear rod 13 passes through the plurality of groups of support rods 17, so that the PCB board 8 is placed on the gear rod 13 of the second rotating part 5, and the rotation transfer operation is completed.

[0040] like Figure 1 As shown, a plurality of groups of feeding brackets 6 are installed on the inner side of one end of the fixed base 1, and a plurality of groups of receiving brackets 2 are installed on the inner side of the other end of the fixed base 1. The plurality of feeding brackets 6 and the plurality of receiving brackets 2 are arranged side by side. The arrangement of the feeding brackets 6 and the receiving brackets 2 can facilitate the loading and discharging operations of the PCB board 8. During loading, the gear lever 13 passes through the receiving bracket 2 to complete the PCB board 8 taking operation. During the receiving operation, when the PCB board 8 rotates to the receiving bracket 2, the first rotating part 3 and the second rotating part 5 pause for a few seconds, so that the PCB board 8 on the first rotating part 3 can slide and transfer on the transfer rack 4, and at the same time, the PCB board 8 on the second rotating part 5 falls into the receiving bracket 2, and is discharged downward by the inclined receiving bracket 2 to avoid affecting the rotation of the second rotating part 5.

[0041] like Figure 5 As shown, guide wheels 16 are provided on the surfaces of the feed bracket 6, the receiving bracket 2 and the support rod 17. The receiving bracket 2 is arranged at an angle, and one end of the receiving bracket 2 is connected to the fixed base 1 through a fixed base plate 19. Both ends of the fixed base plate 19 are fixedly installed with docking strips 22. The upper setting of the guide wheel 16 can reduce the friction of the feed bracket 6, the receiving bracket 2 and the support rod 17 to avoid surface wear on the PCB board body 8. The inclined receiving bracket 2 facilitates the discharge operation of the PCB board body 8.

[0042] To improve the heat dissipation effect of the PCB board, Figure 5 As shown, a bearing 20 is installed at the middle position of the lower end of the side cyclone fan 9, and a turntable 21 is installed at the middle position of the upper end of the side cyclone fan 9. In order to improve the air-cooling and heat dissipation effect of the PCB board 8, the straight-blowing fan structure is adjusted to an oblique-blowing fan structure. By rotating the turntable 21, the side cyclone fan 9 is adjusted by using the setting of the bearing 20, so that the side cyclone fan 9 is as shown in FIG. Figure 7As shown in , the PCB body 8 is subjected to oblique air cooling to dissipate heat, so that the airflow is in full contact with the surface of the PCB body 8, thereby improving the heat dissipation effect of the PCB body 8.

[0043] A turning groove 28 for cooperating with the side cyclone fan 9 is provided on the inner side of the fan frame 10 . The interior of the fixed base 1 is a hollow structure. The use angle of the side cyclone fan 9 can be appropriately adjusted by using the setting of the turning groove 28 .

[0044] To adapt to the installation operation of PCB boards of different sizes, such as Figure 6 As shown, the rotating drum 14 and the gear lever 13 are elastically connected by an elastic sleeve 23, and a rotating sleeve rod 26 is fixedly installed on the outer surface of the rotating rod 15. In order to adapt to the use of PCB boards 8 of different sizes, the elastic sleeve 23 can be used to adjust the length of the gear lever 13, and the rotating sleeve rod 26 is the main component for controlling several groups of gear levers 13.

[0045] A beveled end 25 is provided on the outer surface of one end of the gear rod 13, and a plurality of groups of beveled tops 24 are installed in a ring shape on the outer surface of the rotating sleeve 26. When the rotating sleeve 26 rotates, the beveled tops 24 and the beveled end 25 abut against each other, and the beveled tops 24 push one end of the gear rod 13, thereby adjusting the usable length of the gear rod 13.

[0046] like Figure 8 As shown, the rotating drum 14 and the rotating sleeve rod 26 are fixed together by a telescopic plug rod 27. The outer surface of the rotating sleeve rod 26 is provided with a slot for matching the telescopic plug rod 27. The telescopic plug rod 27 can be used to assist in fixing the rotating drum 14 and the rotating sleeve rod 26. During the adjustment operation, the telescopic plug rod 27 is pulled out so that the rotating sleeve rod 26 can rotate in the rotating drum 14. When in use, the telescopic plug rod 27 is inserted so that the rotating sleeve rod 26 and the rotating drum 14 are in a fixed state.

[0047] When in use, the PCB body 8 after the tin spraying treatment is moved and cooled by adopting a floating bed structure. In order to ensure the cooling effect, the floating bed structure needs to increase the length of the floating bed to make the PCB body 8 contact with the airflow for a longer time, so that the PCB body 8 can achieve a complete cooling effect. However, increasing the length of the floating bed structure increases the overall volume of the floating bed, resulting in a larger area occupied by the floating bed, making it impossible to complete the cooling operation of the PCB body 8 in a limited space;

[0048] To this end, by providing the first rotating part 3, when the PCB board tin spraying floating bed with continuous flip plate cooling is used, it has a flip-type auxiliary cooling structure, thereby replacing the traditional floating bed type moving structure, which can effectively extend the cooling time of the PCB board within a shorter distance and reduce the space occupied by the equipment;

[0049] During operation, the first rotating part 3 is rotated to complete the fan-shaped transfer of the PCB board 8. With the setting of the side cyclone 9, the rotating PCB board 8 can be cooled. The motor 11 drives the gear 12, so that the gear 12 drives the rotating rod 15, and the rotating drum 14 is driven to rotate by the rotating rod 15, so that the several groups of gear rods 13 of the first rotating part 3 and the second rotating part 5 are kept in a rotating state. The conveyor belt 7 is used to convey the PCB board 8 after the tin spraying treatment, so that the PCB board 8 is placed on the upper part of the feeding bracket 6. When the first rotating part 3 rotates, the several groups of gear rods 13 pass through the feeding bracket 6. Through the feeding bracket 6, the plurality of groups of gear levers 13 are in contact with the bottom of the PCB board 8. During the rotation of the plurality of groups of gear levers 13, the PCB board 8 is clamped between the plurality of groups of gear levers 13. The rotation of the plurality of groups of gear levers 13 drives the PCB board 8 to rotate 180 degrees. When the PCB board 8 rotates, the side cyclone fan 9 is used to cool the PCB board 8. The rotating structure of the first rotating part 3 and the second rotating part 5 can realize the rotation operation of the PCB board 8, so that the PCB board 8 makes a fan-shaped movement within a short distance, so that the PCB board 8 can fully dissipate heat and cool within a short distance.

[0050] By setting the intermediate transfer rack 4, when the PCB tin-spraying floating bed with continuous flip plate cooling is used, the use of the first rotating part 3 and the second rotating part 5 can be optimized, so that the PCB board 8 can be transferred between the first rotating part 3 and the second rotating part 5, so that the setting of multiple rotating parts can be completed, the heat dissipation time of the PCB board 8 is effectively extended, and the number of PCB boards 8 of the equipment that can be borne is increased;

[0051] When in use, the inclined transfer rack 4 can cooperate with a plurality of groups of support rods 17 to transfer the PCB board 8 from the first rotating part 3 to the second rotating part 5, thereby completing the transfer operation of the PCB board 8, and the second rotating part 5 can effectively prolong the cooling time of the PCB board 8. During operation, when the PCB board 8 rotates to 180 degrees under the action of the rotating drum 14, the support rod 17 on one side of the transfer rack 4 will contact the surface of the PCB board 8, so that the PCB board 8 slides along the inclined transfer rack 4, from the support rod 17 on one side of the transfer rack 4 to the support rod 17 on the other side. When the second rotating part 5 is in operation, the gear rod 13 passes through a plurality of groups of support rods 17, so that the PCB board 8 is placed on the gear rod 13 of the second rotating part 5, thereby completing the rotation transfer operation;

[0052] The arrangement of the feeding bracket 6 and the receiving bracket 2 can facilitate the loading and discharging operations of the PCB board 8. During loading, the gear lever 13 passes through the receiving bracket 2 to complete the PCB board 8 material taking operation. During the receiving operation, when the PCB board 8 rotates to the receiving bracket 2, the first rotating part 3 and the second rotating part 5 pause for a few seconds, so that the PCB board 8 on the first rotating part 3 can slide and transfer on the intermediate transfer rack 4, and at the same time, the PCB board 8 on the second rotating part 5 falls into the receiving bracket 2, and is discharged downward by the inclined receiving bracket 2 to avoid affecting the rotation of the second rotating part 5.

[0053] By providing the inclined top 24 and the rotating sleeve rod 26, when the PCB tin-spraying floating bed with continuous flip plate cooling is used, the levers 13 of the first rotating part 3 and the second rotating part 5 both have length adjustment structures, so that it can meet the use of PCB boards 8 of different specifications, thereby improving its application range;

[0054] During operation, in order to adapt to the use of PCB boards 8 of different sizes, the elastic sleeve 23 can be used to adjust the length of the gear rod 13, and the rotating sleeve rod 26 is the main component for controlling several groups of gear rods 13. When the rotating sleeve rod 26 rotates, the inclined surface head 24 and the inclined surface end head 25 abut against each other, and the inclined surface head 24 pushes one end of the gear rod 13, thereby synchronously adjusting the use length of several groups of gear rods 13, and the telescopic plug rod 27 can be used to assist in fixing the rotating drum 14 and the rotating sleeve rod 26. During the adjustment operation, the telescopic plug rod 27 is pulled out so that the rotating sleeve rod 26 can rotate in the rotating drum 14.
