[0029] Reference Figure 2The PCB board loading rack 1 includes a loading bracket 11, a load-bearing bracket 12 is slidably installed on the loading bracket 11, a multi-layer placement table 13 is installed on the load-bearing bracket 12, lifting devices 14 are installed at both ends of the load-bearing bracket 12, the lifting device 14 controls the load-bearing bracket 12 to move up and down, a linear limit assembly 15 for limiting the movement of the PCB board is installed on the placement table 13, a pair of conveyor belts 16 are installed on the placement table 13, and a conveying gear 161 is installed at one end of the conveyor belt 16 close to the clutch conveying device 2; the clutch conveying device 2 drives the conveying gear 161 to rotate; the conveyor belts 16 are connected by a rotating connecting rod 17; the rotating connecting rod 17 is installed at one end of the conveyor belt 16 away from the clutch conveying device 2; the PCB board is placed on the upper side of the conveyor belt 16; a mobile base 18 is fixed on the lower side of the load-bearing bracket 12; during the processing of the PCB board , the PCB board is placed on the PCB board feeder 1, the lifting device 14 controls the load-bearing bracket 12 to move up and down, so that the conveyor belt 16 on the placement table 13 is aligned with the clutch conveying device 2, the clutch conveying device 2 controls the conveyor belt 16 to rotate, so that the PCB board on the conveyor belt 16 moves horizontally, and when the PCB board contacts the CNC punching device, the PCB board feeding device 3 conveys the PCB board, and places the PCB board on the CNC punching device. After the PCB board is positioned, the PCB board can be drilled; when the PCB board is punched, the PCB board feeding device 3 conveys the PCB board again, and conveys the PCB board to the conveyor belt 16 along the original path, and the clutch conveying device 2 controls the conveyor belt 16 to rotate again, so that the PCB board is placed on the placement table 13 again; therefore, the use of the PCB board feeder 1 can be reduced;

[0030] A linear limit assembly 15 for limiting the movement of the PCB board is installed on the placement table 13. The positioning bolt installed on the PCB board cooperates with the linear limit assembly 15 to make the PCB board move along a straight line during the conveying process, thereby reducing the position deviation of the PCB board during the conveying process and improving the conveying accuracy.

[0031] The PCB board is conveyed by rotating the conveyor belt 16. When the PCB board contacts the CNC punching device, it is conveyed by the PCB board feeding device 3, so that the PCB board always has a supporting force at the bottom during the conveying process, thereby effectively preventing the PCB board from breaking during the conveying process.

[0032] A mobile base 18 is fixed on the lower side of the load-bearing bracket 12. The mobile base 18 can be used to transfer the PCB board feed rack 1 and the PCB board placed on the PCB board feed rack 1. The PCB board and the PCB board feed rack 1 are transferred together to the next processing link. In the next processing link, the clutch conveying device 2 is used to control the conveyor belt 16 to rotate again to convey the PCB board, thereby reducing the use of the PCB board feed rack 1 and the use of manipulators, thereby reducing the production cost of the enterprise.

[0033] Reference Figure 3 , Figure 4 The clutch conveying device 2 includes a clutch bracket 21 fixed on the feeding bracket 11, a clutch motor 22 is fixed on the clutch bracket 21, a clutch shaft 23 is rotatably mounted on the clutch bracket 21, a pair of clutch drive gears 24 are fixed on the clutch shaft 23, a pair of damping sleeves 25 are mounted on the clutch shaft 23, a pair of clutch linkage plates 26 are rotatably mounted on the clutch shaft 23, a clutch driven gear 27 is mounted on the clutch linkage plate 26, the clutch driven gear 27 is meshed with the clutch drive gear 24, and the clutch linkage plate 26 The clutch linkage plate 26 is connected to the damping sleeve 25 through the torsion spring 28; the damping sleeve 25 is used to control the clutch linkage plate 26 to flip so that the clutch driven gear 27 is meshed with the conveying gear 161; the clutch motor 22 drives the clutch shaft 23 to rotate, and the clutch driven gear 27 on the clutch linkage plate 26 rotates synchronously with the clutch driving gear 24. The clutch linkage plate 26 flips under the action of the torsion spring 28 and the damping sleeve 25, so that the clutch driven gear 27 is meshed with the conveying gear 161, thereby driving the conveyor belt 16 to rotate to convey the PCB board;

[0034] There is a certain angle between the clutch linkage plates 26, so that the clutch driven gear 27 on the clutch linkage plate 26 is respectively located on the upper and lower sides of the conveying gear 161; when the clutch motor 22 rotates forward, the clutch linkage plate 26 located on the lower side flips upward, so that the clutch driven gear 27 on the lower side of the conveying gear 161 is meshed with the conveying gear 161, so that the PCB board on the PCB board feed rack 1 is conveyed to the direction of the CNC punching device; when the clutch motor 22 rotates reversely, the clutch linkage plate 26 flips downward, and the clutch driven gear 27 on the upper side of the conveying gear 161 is meshed with the conveying gear 161, so that the PCB board conveyed by the PCB board feeding device 3 to the direction of the PCB board feed rack 1 moves toward the direction of the PCB board feed rack 1, and the PCB board with holes is placed on the PCB board feed rack 1; thereby, the PCB board is moved back and forth between the CNC punching device and the PCB board feed rack 1, thereby reducing the use of the PCB board feed rack 1.

[0035] An initial limiting member 211 is installed on the upper side of the clutch bracket 21. A limiting groove 212 is provided on the upper side of the clutch bracket 21. The initial limiting member 211 is installed at both ends of the limiting groove 212 to form an "eight" structure. The initial limiting member 211 and the limiting groove 212 are aligned with the linear limiting assembly 15. The initial limiting member 211 cooperates with the linear limiting assembly 15 to limit the PCB board to move along a straight line.

[0036] When the PCB board is moved from the PCB board feeder 1 to the CNC punching device, the limit bolt on the PCB board moves from the linear limit assembly 15 to the initial limit piece 211, so that the PCB board keeps moving in a straight line. When the PCB board is moved from the CNC punching device to the PCB board feeder 1, the limit bolt on the PCB board moves from the initial limit piece 211 to the linear limit assembly 15, so that the PCB board keeps moving in a straight line, thereby ensuring the accuracy of the PCB board during the conveying process;

[0037] The initial limiting member 211 is installed at both ends of the limiting groove 212, and has an eight-shaped structure. During the conveying process of the PCB board, the initial limiting member 211 can cooperate with the limiting bolt to correct the conveying track of the PCB board, so that the PCB board keeps moving in a straight line, thereby improving the conveying accuracy;

[0038] A sensor is installed at the lower side of the limit slot 212. The sensor is electrically connected to the clutch motor 22. The sensor senses the position of the limit bolt, determines the position of the PCB board, and controls the clutch motor 22 to rotate and stop.

[0039] A sliding roller 213 is installed on the upper side of the clutch bracket 21; the sliding roller 213 is installed on both sides of the clutch bracket 21. When the PCB board is connected to the clutch bracket 21, the sliding roller 213 reduces the contact area between the PCB board and the clutch bracket 21, and at the same time changes the static friction into rolling friction. Therefore, the sliding roller 213 is used to reduce the friction between the PCB board and the clutch bracket 21, which can reduce the wear of the PCB board.

A G-shaped support frame 321 is fixedly installed on the fixed plate 32, and the driven chain belt 332 is locked on the G-shaped support frame 321. The driving chain belt 38 passes through the G-shaped support frame 321 and does not contact the G-shaped support frame 321;

[0041] The connecting bracket 31 is fixed on the CNC punching equipment, and when the feeding drive motor 36 is rotated, the chain belt 38 is driven to rotate, and the traction sliding plate 33 is moved on the fixed plate 32, and the driven chain belt 332 is locked and fixed on the G-shaped support frame 321 on the fixed plate 32. When displacement occurs between the sliding plate 33 and the fixed plate 32, the driven chain belt 332 sleeved on the second support roller 331 starts to rotate, and the traction sliding seat 34 is horizontally displaced on the sliding plate 33, so that the transport assembly 35 can move horizontally on the sliding plate 33, and when the transport assembly 35 is connected to the PCB board, it can pull the PCB board to move horizontally; the feeding drive motor 36 controls the traction sliding plate 33 to move on the fixed plate 32, and controls the sliding seat 34 and the transport assembly 35 to move on the sliding plate 33;

[0042] When the sliding plate 33 overlaps with the fixed plate 32, the sliding seat 34 is located at one end close to the CNC punching device. When the sliding plate 33 extends toward the PCB board feed rack 1, the sliding seat 34 and the transport assembly 35 move to one end of the sliding seat 34 close to the PCB board feed rack 1 under the action of the driving chain belt 38, the driven chain belt 332 and the G-shaped support frame 321. At this time, the transport assembly 35 can be connected to the PCB board;

[0043] When the PCB board is moved from the PCB board feed rack 1 to the CNC punching device, the feed drive motor 36 is controlled to rotate in the forward direction, the sliding plate 33 and the fixed plate 32 are pulled to overlap each other, and the transport component 35 moves from the PCB board feed rack 1 to the CNC punching device, so that the PCB board can be moved from the PCB board feed rack 1 to the CNC punching device;

[0044] When the PCB board is moved from the CNC punching device to the PCB board feed rack 1, the feeding drive motor 36 is controlled to rotate in the reverse direction, the sliding plate 33 is pulled to extend, and the conveying component 35 moves from the CNC punching device to the PCB board feed rack 1. At this time, the PCB board can be conveyed to the PCB board feed rack 1. When the PCB board contacts the conveyor belt 16, the clutch conveying device 2 controls the conveyor belt 16 to rotate, and the PCB board is placed on the PCB board feed rack 1 again.

[0045] Reference Figure 6The transport assembly 35 includes a transport seat 351 fixed on the sliding seat 34, a telescopic member 352 fixed on the transport seat 351, and a push frame 353 fixed on the transport seat 351. The output end of the telescopic member 352 passes through the push frame 353. A limit head 354 is fixed on the output end of the telescopic member 352. The limit head 354 is used to be inserted into the positioning hole of the PCB board. A sensor for sensing the PCB board is installed on the transport seat 351, and the sensor controls the movement of the telescopic member 352. When the PCB board is sensed, the telescopic member 352 extends to control the limit head 354 to pass through the push frame 353 and insert into the limit hole of the PCB board. At this time, the PCB board can be pulled to move horizontally. When the PCB board is moved to the specified position, the telescopic member 352 shortens and shrinks to the inner side of the push frame 353, so that the limit head 354 is pulled out of the limit hole of the PCB board and separated from the PCB board. Because the PCB board always moves in a straight line, the transport assembly 35 can be quickly connected with the PCB board to pull the PCB board.
