It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0033] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0034] like Figures 1 to 6 As shown, the embodiment of the utility model provides an automatic patch device for flexible circuit boards, including a frame 1, a first conveyor belt 21, a second conveyor belt 22, a bin lifting mechanism 3, a tray clamping mechanism 4, a three-axis moving mechanism 5 and a patch manipulator 6;

[0035] The first conveyor belt 21 and the second conveyor belt 22 are arranged in the middle of the frame 1, and the first conveyor belt 21 is located above the second conveyor belt 22. The first conveyor belt 21 and the second conveyor belt 22 are both used to convey the positioning fixture 23 clamped with the flexible circuit board; such arrangement enables the present patch device to process two flexible circuit boards at the same time, realize parallel operation, and thus significantly improve production efficiency; and the installation structure of the first conveyor belt 21 and the second conveyor belt 22 arranged vertically up and down can make full use of the vertical space and improve the space utilization rate of the equipment. In this embodiment, the first conveyor belt 21 and the second conveyor belt 22 have the same structure and are both ring-shaped belt conveying devices.

[0036] The tray clamping mechanism 4 is arranged on the frame 1 on both sides of the first conveyor belt 21. The tray clamping mechanism 4 is used to clamp the tray equipped with patch components. The silo lifting mechanism 3 is arranged below the tray clamping mechanism 4. The silo lifting mechanism 3 is used to lift and transport the tray for the tray clamping mechanism 4. The silo lifting mechanism 3 can transport the tray from the bottom of the frame 1 to the tray clamping mechanism 4 through lifting movement. The tray clamping mechanism 4 can stably clamp the tray to prevent the tray from moving during operation, thereby ensuring the accuracy of the component position.

[0037] The three-axis moving mechanism 5 is arranged above the tray clamping mechanism 4, and the patch robot 6 is connected to the three-axis moving mechanism 5. The patch robot 6 is used to adsorb and mount the patch components on the tray on the flexible circuit board on the first conveyor belt 21 or the second conveyor belt 22; the three-axis moving mechanism 5 can accurately position and move the patch robot 6 in three directions of X-axis, Y-axis and Z-axis, so that it can accurately pick up components from the tray and mount them on the flexible circuit board.

[0038] like Figures 1 to 3As shown, the patch robot 6 includes a connecting plate 61, a first cylinder 62, an anti-sticking pressure plate 63, a second cylinder 64 and a vacuum suction head 65. The connecting plate 61 is connected to the three-axis moving mechanism 5. The two first cylinders 62 are respectively arranged on both sides of the connecting plate 61. The movable end of the first cylinder 62 is set downward and connected to the anti-sticking pressure plate 63. The second cylinder 64 is arranged on the connecting plate 61. The movable end of the second cylinder 64 is connected to the vacuum suction head 65. The vacuum suction head 65 is used to adsorb the patch components on the tray. The vacuum suction head 65 can pick up the patch components on the tray by vacuum adsorption. When the patch robot 6 moves to the top of the flexible circuit board under the action of the three-axis moving mechanism 5, the first cylinder 62 can drive the anti-sticking pressure plate 63 to press on the surface of the flexible circuit board, and then the second cylinder 64 drives the vacuum suction head 65 to move to mount the patch components on the patch position on the flexible circuit board. This arrangement can prevent the flexible circuit board from being bent or deformed by external force during the mounting process, thereby improving the stability and accuracy of the mounting.

[0039] like Figures 1 to 3 As shown, further, the three-axis moving mechanism 5 includes a support seat 51, an X-axis moving assembly 52, a Y-axis moving assembly 53 and a Z-axis moving assembly 54. The support seat 51 is arranged on the frame 1, the X-axis moving assembly 52 is arranged on the support seat 51, the Y-axis moving assembly 53 is connected to the X-axis moving assembly 52, the Z-axis moving assembly 54 is arranged on the Y-axis moving assembly 53, and the Z-axis moving assembly 54 is connected to the patch manipulator 6. The X-axis moving assembly 52 can drive the patch manipulator 6 to move in the X-axis direction, the Y-axis moving assembly 53 can drive the patch manipulator 6 to move in the Y-axis direction, and the Z-axis moving assembly 54 can drive the patch manipulator 6 to move in the Z-axis direction. It should be noted that since the X-axis moving assembly 52, the Y-axis moving assembly 53 and the Z-axis moving assembly 54 are already disclosed prior art, this embodiment will not elaborate on their specific structures and working principles.

[0040] like Figure 2 and Figure 4As shown, further, the silo lifting mechanism 3 includes a positioning silo 31, a screw lifting assembly 32 and a lifting plate 33. The positioning silo 31 is arranged at the bottom of the frame 1. The positioning silo 31 is used to place the pallet to be loaded. A lifting avoidance groove 310 is arranged in the middle of the positioning silo 31. The screw lifting assembly 32 is connected to the lifting plate 33. The lifting plate 33 is used to lift the pallet. The screw lifting assembly 32 is used to drive the lifting plate 33 to move up and down in the lifting avoidance groove 310. When it is necessary to supply the pallet to the pallet clamping mechanism 4, the screw lifting assembly can drive the lifting plate 33 to rise, so as to lift and move the pallet through the lifting plate 33.

[0041] like Figure 1 and Figure 5 As shown, further, the pallet clamping mechanism 4 includes a third cylinder 41, a side clamping plate 42, a first slide rail 43 and a first slider 44. The frame 1 is provided with a slot for the lifting plate 33 to be lifted and lowered, and the two side clamping plates 42 are respectively arranged on both sides of the slot.

The first slide rail 43 is arranged on the frame 1 and is arranged along the extension and retraction direction of the third cylinder 41. The first slide rail 43 is connected to the side clamping plate 42 through the first slider 44. When the hopper lifting mechanism 3 transports the tray into the slot, the third cylinder 41 can drive the side clamp 42 to be pushed outward so that the side clamp 42 can clamp the tray laterally to prevent the tray from shifting during the patch process, thereby improving the picking accuracy of the patch components; the setting of the first slide rail 43 and the first slider 44 can improve the movement stability of the side clamp 42.

[0042] like Figure 5 As shown, further, the pallet clamping mechanism 4 also includes a limit block 45, and the limit block 45 is arranged on both sides of the side clamping plate 42. A rubber pad 451 is provided at the bottom of the limit block 45. The limit block 45 is used to limit the lifting movement stroke of the pallet to prevent the lifting movement stroke from being too large and exceeding the clamping height range of the pallet clamping mechanism 4. The setting of the rubber pad 451 can reduce the impact force of the pallet when it is lifted and abutted against the limit block 45, thereby improving the service life of the equipment.

[0043] like Figures 1 to 3As shown, further, a CCD detection camera 7 is included, and the CCD detection camera 7 is arranged on the Z-axis moving component 54, and the CCD detection camera 7 is used to detect the position of the patch components on the tray. The CCD detection camera 7 can detect the specific position of each patch component on the tray in real time through image acquisition and processing, including X, Y coordinates and angle information, and feed back the detected position data to the control system, so that the patch robot 6 can accurately locate the position of the component to ensure the accuracy of picking and mounting.
