[0032] As Figure 1As shown in the figure, the utility model discloses an automatic transmission device 100 for a mobile terminal PCB, including a main bracket 10. An upper feeding mechanism 20, a transmission mechanism 30 and a combination mechanism 40 are arranged on the main bracket 10. The transmission mechanism 30 is used for linearly transmitting a jig board 50. The upper feeding mechanism 20 and the combination mechanism 40 cooperate to place a PCB board on the jig board 50 at a preset position, and then the transmission mechanism 30 can drive the jig board 50 with the PCB board placed thereon to continue moving.

[0033] As Figure 2 and Figure 3 shown in the figure, specifically, the transmission mechanism 30 includes a first transmission line 31 and a second transmission line 32. Both the first transmission line 31 and the second transmission line 32 are fixed on the main bracket 10. The first transmission line 31 and the second transmission line 32 are arranged opposite to each other. The first transmission line 31 and the second transmission line 32 cooperate to drive the jig board 50 to move linearly.

[0034] Specifically, the first transmission line 31 and the second transmission line 32 have the same structure. Both the first transmission line 31 and the second transmission line 32 include a transmission bracket 311, a transmission belt 312 and a driving device 313. A sliding table 315 is arranged inside the transmission bracket 311. The transmission belt 312 is arranged on the transmission bracket 311 through a guide wheel 314. The transmission part on the transmission belt 312 fits the sliding table 315. The driving device 313 drives the transmission belt 312 to slide relative to the sliding table 315. The two side edges of the jig board 50 are respectively placed on the two sliding tables 315. The transmission belt 312 can drive the jig board 50 to slide relative to the sliding table 315. In this application, the transmission belt 312 is located inside the transmission bracket 311. The bottom surface of the transmission bracket 311 is fixedly connected to the main bracket 10. A plurality of guide wheels 314 are rotatably connected to the inner side wall of the transmission bracket 311. The transmission belt 312 is arranged on the transmission bracket 311 through the guide wheels 314. The driving device 313 can drive the transmission belt 312 to rotate. When the jig board 50 is placed on the sliding table 315 and contacts the transmission belt 312, the movement of the transmission belt 312 can drive the jig board 50 to move linearly.

[0035] In this application, the driving device 313 includes a driving motor, and the driving motor can drive the transmission belt 312 to work through a belt pulley.

[0036] Further, the guide wheel 314 is fixed to the transmission bracket 311 by a screw and its position on the transmission bracket 311 can be adjusted to adjust the tension of the transmission belt 312.

[0037] AsFigure 4 As shown in the figure, further, a driving groove 316 is provided on the top surface of the sliding table 315. A part of the transmission belt 312 is located in the driving groove 316 and the top surface of the transmission belt 312 protrudes from the driving groove 316. When the jig plate 50 is placed on the sliding table 315, it contacts the transmission belt 312.

[0038] As Figure 2 shown in the figure, further, the transmission mechanism 30 includes a stop assembly 33. The stop assembly 33 includes a stop cylinder 331 and a stop plate 332. The stop plate 332 is located between the first transmission line 31 and the second transmission line 32. The stop cylinder 331 can drive the stop plate 332 to move in the vertical direction. The stop plate 332 can stop the jig plate 50 at a preset position so as to drive the jig plate 50 to move in the vertical direction through the combination mechanism 40. Specifically, when the stop cylinder 331 drives the stop plate 332 to rise to the preset position, at this time, the top surface of the stop plate 332 is at least higher than the height of the sliding table 315. When the transmission mechanism 30 drives the jig plate 50 to move to the preset position, the stop plate 332 can prevent the jig plate 50 from continuing to move. At this time, the combination mechanism 40 can drive the jig plate 50 to move upward to the combination station to disengage from the transmission mechanism 30. Then, the feeding mechanism 20 can grab the PCB board and move it onto the jig plate 50. Then, the combination mechanism 40 drives the jig plate 50 to move downward until the jig plate 50 is placed on the first transmission line 31 and the second transmission line 32. The stop assembly 33 resets. At this time, the first transmission line 31 and the second transmission line 32 drive the jig plate 50 carrying the PCB board to continue to move.

[0039] As Figure 5 shown in the figure, specifically, the combination mechanism 40 is arranged on one side of the stop assembly 33. The combination mechanism 40 is fixedly connected to the main bracket 10. The combination mechanism 40 is used to drive the jig plate 50 at the preset position to move upward to the combination station to disengage from the first transmission line 31 and the second transmission line 32, and drive the jig plate 50 to move downward to place the jig plate 50 on the first transmission line 31 and the second transmission line 32. Further, the combination mechanism 40 includes a driving cylinder 41 and a support plate 42. The support plate 42 is located between the first transmission line 31 and the second transmission line 32. The output shaft of the driving cylinder 41 is connected to the support plate 42 and can drive the support plate 42 to move in the vertical direction. The driving cylinder 41 drives the jig plate 50 to move to the combination station through the support plate 42.

[0040] When the transfer mechanism 30 drives the jig plate 50 to move to a preset position and the stopper assembly 33 stops the jig plate 50, the driving cylinder 41 can drive the jig plate 50 to move upward through the support plate 42 so that the jig plate 50 disengages from the transfer mechanism 30.

[0041] As Figure 6 and Figure 7 shown, at least one positioning block 51 is provided on the bottom surface of the jig plate 50, and a positioning groove 421 corresponding to the positioning block 51 is provided on the support plate 42. When the jig plate 50 is placed on the support plate 42, the positioning block 51 extends into the positioning groove 421 to positionally cooperate the jig plate 50 and the support plate 42. At this time, displacement of the jig plate 50 relative to the support plate 42 can be prevented, ensuring the accuracy of the position of the jig plate 50.

[0042] The combination mechanism 40 further includes an upper pressing plate 43. The upper pressing plate 43 is located directly above the support plate 42. A plurality of stoppers 431 are provided on the upper pressing plate 43. When the driving cylinder 41 drives the jig plate 50 to move to a preset position through the support plate 42, the stoppers 431 abut against the top surface of the jig plate 50 to position the jig plate 50 at the combination station. In the present application, the stopper 431 can be connected to the upper pressing plate 43 by bolts. Rotating the bolts can adjust the height of the stopper 431, and thus adjust the height of the jig plate 50 at the combination station. When the jig plate 50 moves to the combination station, the stopper 431 abuts against the upper surface of the jig plate 50. At this time, the highest position of the jig plate 50 can be controlled, and then the feeding mechanism 20 can place the PCB on the jig plate 50.

[0043] A material passing hole 432 is provided on the upper pressing plate 43. The material passing hole 432 penetrates through the upper pressing plate 43. The material passing hole 432 allows the PCB to pass through. The feeding mechanism 20 grabs the PCB and places the PCB on the jig plate 50 at the combination station through the material passing hole 432.

[0044] As Figure 8As shown, further, the feeding mechanism 20 includes a first feeding cylinder 21, a second feeding cylinder 22, a negative pressure gripper 23 and a placing component 24. The placing component 24 is used for stacking and placing a plurality of PCB boards. The first feeding cylinder 21 is fixed on the main bracket 10 through a feeding bracket. The first feeding cylinder 21 can drive the second feeding cylinder 22 to move in the horizontal direction. The second feeding cylinder 22 can drive the negative pressure gripper 23 to move in the vertical direction. The negative pressure gripper 23 is used for adsorbing the PCB board on the placing component 24. The placing component 24 includes a placing rack 241, a third feeding cylinder 242 and a placing platform 243. The placing platform 243 is slidably arranged on the placing rack 241. The third feeding cylinder 242 is fixedly connected to the main bracket 10 and can drive the placing platform 243 to move relative to the placing rack 241. The PCB boards are stacked on the placing platform 243. During feeding, a plurality of PCB boards are stacked on the placing platform 243. The first feeding cylinder 21 and the second feeding cylinder 22 cooperate to grab the topmost PCB board from the placing platform 243 through the negative pressure gripper 23 and move it to the combination station for placing on the jig board 50. The third feeding cylinder 242 drives the placing platform 243 to move in the vertical direction, so that the PCB board can be moved to a position where it can be grabbed by the negative pressure gripper 23.

[0045] In the present application, the negative pressure gripper 23 includes a mounting plate 231. A plurality of suction heads 232 are arranged on the mounting plate 231. The output end of the second feeding cylinder 22 is connected to the mounting plate 231 and moves the suction heads 232 through the mounting plate 231. The negative pressure gripper 23 grabs the PCB board through the suction heads 232.

[0046] Without departing from the broad spirit and scope of the present utility model, it can be set into various embodiments and deformations. The above embodiments are used to illustrate the utility model, but do not limit the scope of the present utility model.
