[0074] The base 1 is a rectangular plate-shaped structure, and a plurality of mounting holes are provided at the corners of the base plate, and the mounting holes are used for fixing and installing the base 1 .

[0075] The frame is arranged on the base 1 by fasteners, and the frame includes a first bracket 11 and a second bracket 12 arranged opposite to each other, and a certain interval is set between the first bracket 11 and the second bracket 12, and the distance between the first bracket 11 and the second bracket 12 is greater than the width of the PCB board 9 to be placed.

[0076] Combination Figure 1 and Figure 2 As shown, the pressing plate 2 is a rectangular plate-shaped structure, and is fixed to the upper ends of the first bracket 11 and the second bracket 12 by fasteners such as bolts.

[0078] The ejection mechanism 4 is arranged below the feeding mechanism 3 and corresponds to the position of the pressing plate 2. The bottom end of the ejection mechanism 4 is fixed above the base 1. The ejection mechanism 4 is used to eject the PCB board 9 on the feeding mechanism 3 to the pressing plate 2 and abut against the pressing plate 2, thereby flattening the PCB board 9. The ejection mechanism 4 and the pressing plate 2 form a clamp for the PCB board 9, which restricts the PCB board 9 during the mounting process of the PCB board 9 to prevent it from moving.

[0079] Combination Figure 4As shown, the feeding mechanism 3 includes a grabbing portion 31 and a conveying portion 32. The grabbing portion 31 is arranged at the end of the frame. The grabbing portion 31 can be arranged in one group or in two groups symmetrically, that is, they are respectively fixed at the ends of the first bracket 11 and the second bracket 12.

[0080] A material cage for storing PCB boards 9 is provided on one side of the device for PCB board mounting of the present application. The material cage is used to provide PCB boards 9 to be mounted and to store mounted PCB boards 9.

[0081] Before mounting, the grabbing portion 31 extends into the material cage and grabs the PCB board 9 from the material cage, and places the PCB board 9 on the conveying portion 32. The conveying portion 32 conveys the PCB board 9 forward until it is transported to the top of the ejection mechanism 4, and then the ejection mechanism 4 ejects the PCB board 9 on the conveying portion 32 to the pressing plate 2 for flattening, and the mounting equipment mounts the PCB board 9; after mounting, the ejection mechanism 4 is retracted, and the PCB board 9 falls back onto the conveying portion 32, and then the conveying portion 32 transports the PCB board 9 in the reverse direction to the grabbing portion 31, and the grabbing portion 31 grabs the PCB board 9 and drives it back into the material cage.

[0082] Specifically, a frame is arranged on the base 1, and a pressing plate 2 and a feeding mechanism 3 are arranged on the frame. The pressing plate 2 is arranged at the upper end of the frame. A mounting hole 21 for mounting a PCB board 9 is formed on the pressing plate 2, and the mounting hole 21 corresponds to the position to be mounted on the PCB board 9; an ejection mechanism 4 is arranged at a position corresponding to the pressing plate 2 below the feeding mechanism 3; the feeding mechanism 3 includes a grabbing part 31 and a conveying part 32. Before mounting, the grabbing part 31 is used to grab the PCB board 9 from the material cage and place it on the conveying part 32, and the conveying part 32 conveys the PCB board 9 to the top of the ejection mechanism 4, and the ejection mechanism 4 ejects the PCB board 9 to the pressing plate 2 for flattening, which is convenient for mounting the PCB board 9, and the mounting consistency is good, which is conducive to ensuring product quality.

[0083] At the same time, the conveying part 32 conveys the PCB board 9 in reverse to the grabbing part 31, and the grabbing part 31 grabs the PCB board 9 and puts it back into the material cage, thereby completing the entire mounting process of the PCB board 9. The present application has a high degree of automation in transporting the PCB board 9, improves the loading and unloading efficiency of the PCB board 9, and reduces labor costs.

[0084] In some embodiments of the present application, Figure 3 As shown, the conveying portion 32 includes a driving motor 321 , a driving wheel 322 and a transmission wheel 323 .

[0085] The driving motor 321 is fixedly disposed on the first bracket 11 and is located between the first bracket 11 and the second bracket 12. The output shaft of the driving motor 321 passes through the first bracket 11.

[0086] The driving wheel 322 is located outside the first bracket 11, and the driving wheel 322 is drivingly connected to the output shaft of the driving motor 321. When the driving motor 321 is powered on, the driving wheel 322 can be driven to rotate;

[0087] The transmission wheel 323 includes a first transmission wheel 323, a second transmission wheel 323 and a third transmission wheel 323, wherein the first transmission wheel 323 and the second transmission wheel 323 are rotatably arranged on both sides of the first bracket 11, wherein the first transmission wheel 323 is located on the outer side of the first bracket 11, the second transmission wheel 323 is located on the inner side of the first bracket 11, and the third transmission wheel 323 is rotatably arranged on the second bracket 12, the second transmission wheel 323 and the third transmission wheel 323 are arranged oppositely, and the first transmission wheel 323, the second transmission wheel 323 and the third transmission wheel 323 are arranged coaxially. On the outer side of the first bracket 11, the driving wheel 322 is connected to the first transmission wheel 323 in transmission; since the first transmission wheel 323, the second transmission wheel 323 and the third transmission wheel 323 are arranged coaxially, when the first transmission wheel 323 rotates, it will drive the second transmission wheel 323 and the third transmission wheel 323 to rotate.

[0088] Specifically, the driving wheel 322 is connected to the first transmission wheel 323 through a belt transmission, or the driving wheel 322 is connected to the transmission wheel 323 through gear meshing, which can be set according to actual needs.

[0089] A plurality of driven wheels 324 are rotatably disposed on the first bracket 11 and the second bracket 12;

[0090] The conveyor belt includes a first conveyor belt 325 and a second conveyor belt 326. On the first bracket 11, a part of the driven wheel 324 is connected to the second transmission wheel 323 through the first conveyor belt 325. On the second bracket 12, another part of the driven wheel 324 is connected to the third transmission wheel 323 through the second conveyor belt 326. Since the second transmission wheel 323 and the third transmission wheel 323 are coaxially arranged, the two rotate synchronously, and therefore, the first conveyor belt 325 and the second conveyor belt 326 also rotate synchronously.

[0091] The first conveyor belt 325 and the second conveyor belt 326 are used to receive the PCB board 9 .

[0092] In some embodiments of the present application, the conveying portion 32 further includes a pressure roller assembly 327 .

[0094] Specifically, by setting a pressure roller assembly 327 at the upper ends of the first bracket 11 and the second bracket 12, the pressure roller assembly 327 is used to press the PCB board 9 toward the conveyor belt, which is beneficial to increase the friction between the PCB board 9 and the conveyor belt, thereby better conveying the PCB board 9 and avoiding transportation failures such as slipping of the PCB board 9 during transportation.

[0095] In certain embodiments of the present application, Fig.10 As shown, the pressure roller assembly 327 includes a fixing member 3271 , a connecting member 3272 , a rotating wheel 3273 and an elastic member 3274 .

[0100] The elastic member 3274 is sleeved on the fixing member 3271 and is located between the fixing member 3271 and the connecting member 3272. The elastic member 3274 is configured to elastically abut the rotating wheel 3273 against the first conveyor belt 325. After the grabbing portion 31 grabs the PCB board 9, it is sent between the first conveyor belt 325 and the rotating wheel 3273. The PCB board 9 moves with the movement of the first conveyor belt 325.

[0101] Specifically, the tensioning force of the elastic member 3274 can be adjusted by adjusting the height of the fixing member 3271 relative to the first bracket 11 .

[0106] The in-position sensor 6 is disposed at the other end of the base 1 and is located below the first conveyor belt 325 and the second conveyor belt 326 . The in-position sensor 6 is configured to sense whether the PCB board 9 reaches the ejection position on the conveyor belt.

[0107] Combination Figure 8 As shown, in some embodiments of the present application, the gripping portion 31 includes a first cylinder 311 , a second cylinder 312 and a chuck 313 .

[0108] The gripping portion 31 can be disposed on the first bracket 11 and the second bracket 12, or can be disposed on the first bracket 11 or the second bracket 12 alone, and can be disposed specifically according to actual needs.

[0109] The first cylinder 311 is disposed on the frame in a transverse direction, and the piston rod of the first cylinder 311 can be extended and retracted in a transverse direction;

[0110] The second cylinder 312 is connected to the piston rod of the first cylinder 311, and the first cylinder 311 is used to drive the second cylinder 312 to move towards or away from the material cage;

[0111] The clamp 313 is drivingly connected to the second cylinder 312 , and the second cylinder 312 is configured to drive the clamp 313 to clamp or release the PCB board 9 .

[0112] Specifically, when feeding is required, the piston rod of the first cylinder 311 extends and drives the second cylinder 312 to move toward the direction close to the material cage. The second cylinder 312 controls the clamp 313 to clamp the PCB board 9. Then the piston rod of the first cylinder 311 contracts, driving the second cylinder 312 to move in the direction away from the material cage, clamping the PCB board 9 until the PCB board 9 is sent to the first conveyor belt 325 and the second conveyor belt 326, and the PCB board 9 is pressed toward the first conveyor belt 325 and the second conveyor belt 326 by the rotating wheel 3273 of the pressure roller assembly 327, and the PCB board 9 is transported to the bottom of the pressure plate 2 by the first conveyor belt 325 and the second conveyor belt 326.

[0120] Specifically, by providing the limiter 7 , the limiter 7 can stop the PCB board 9 from moving in time, thereby preventing the PCB board 9 from moving beyond the limiter 7 .

[0121] Specifically, the working process of the ejection mechanism 4 is as follows: the first conveyor belt 325 and the second conveyor belt 326 convey the PCB board 9 to move toward the bottom of the pressure plate 2. When the PCB board 9 moves to the limiter 7, the limiter 7 prevents the PCB board 9 from continuing to move, and the piston rod of the third cylinder 41 extends, driving the cylinder top plate to move upward, and in turn driving the support plate 43 and the PCB board 9 to move upward until the PCB board 9 is pushed against the pressure plate 2.
