[0002] In the 3C positioner, when the bin tray is relatively large, there will be the following problems: First, the robot needs to use a large range, which leads to high cost and large space occupation. Second, the distance of the distant tray is relatively long, which affects the cycle time. Third, in order to save time, it is necessary to add a CCD positioning mechanism to the XY module mechanism above the bin, which will cause the XY module mechanism to be bloated, occupy a large space, and have high cost. If the CCD positioning mechanism is installed on the robot, the cycle time will increase.

[0029] The transport mechanism includes a Y module 6 and an X module 7 arranged on the Y module 6, the Y module 6 includes a first slide rail 61 arranged on the frame 1, a crossbeam 63 slidably arranged on the first slide rail 61, and a sixth driver 62 driving the crossbeam 63 to move along the first slide rail 61, and the first slide rail 61 extends along the Y-axis direction; a clamping claw assembly 8 is provided on the Y module 6, and the Y module 6 drives the X module 7 and the clamping claw assembly 8 to move along the Y-axis direction, and the clamping claw assembly 8 is connected by a connecting plate 82 Connected to the cross beam 63, the X module 7 is provided with a material picking component 9 and a CCD component 10. The X module 7 includes a second slide rail 71 and a seventh driver 72 arranged on the cross beam 63. The second slide rail 71 extends along the X-axis direction. The material picking component 9 and the CCD component 10 are slidably arranged on the second slide rail 71. The seventh driver 72 drives the material picking component 9 and the CCD component 10 to move along the X-axis direction.

The clamping claw assembly 8 is used to clamp the empty trays on the first upper bin 3 and the second upper bin 5.

[0030] In one embodiment of the present invention, referring to Figure 1 As shown, the first loading bin 3 and the second loading bin 5 are respectively provided with a first feeding mechanism 32 and a second feeding mechanism 52 at the bottom, and the lower bin 4 is provided with an empty tray transfer mechanism 42. The first feeding mechanism 32 and the second feeding mechanism 52 both include two first conveyor belts 321 horizontally and spaced apart and a first driver 322 for driving the first conveyor belts 321 to transmit.

The empty tray transfer mechanism 42 is used to transport the empty tray of the stacked paper in the lower bin 4 to the loading station.

[0031] In one embodiment of the present invention, referring to Figure 3 As shown, a first full tray lifting mechanism 31 and a second full tray lifting mechanism 51 are respectively provided inside the first loading bin 3 and the second loading bin 5. The first full tray lifting mechanism 31 and the second full tray lifting mechanism 51 both include a first carrier 311 and a third driver for driving the first carrier 311 to move along the Z-axis direction. The first carrier 311 can pass through the gap between the two first conveyor belts 321, so that the first carrier 311 can support the full tray 2 located on the two first conveyor belts 321.

[0032] In one embodiment of the present invention, referring to Figure 3 As shown, the lower material bin 4 is provided with an empty tray lifting mechanism 41, and the empty tray lifting mechanism 41 includes a second carrier and a fourth driver for driving the second carrier to move along the Z-axis direction, and the second carrier can pass through the gap between the two second conveyor belts, so that the two sides of the empty tray on the second carrier can abut against the two second conveyor belts, so that the tray transfer mechanism can transport the empty tray away.

[0033] In one embodiment of the present invention, referring to Figure 4 As shown, the material picking component 9 includes an adsorption component and a fifth driver 91 for driving the adsorption component to move along the Z-axis direction. The adsorption component is used to adsorb the workpieces on the full material tray 2. The fifth driver 91 drives the adsorption component to descend in order to adsorb the workpieces, and then rises to a certain height again after adsorption to avoid the frame 1 and the workpieces.

[0034] In one embodiment of the utility model, the adsorption component is provided with a spring suction nozzle 93, which adsorbs the workpiece through vacuum adsorption force and can also buffer the suction nozzle through a spring to prevent the suction nozzle from crushing the workpiece.

[0035] In one embodiment of the present invention, referring to Figure 5 As shown, the material picking assembly 9 includes a mounting seat and a third slide rail 95 arranged on the mounting seat 96, and a slider 94 slidably connected to the third slide rail 95, the CCD assembly and the fifth driver 91 are both connected to the mounting seat 96, the adsorption component is arranged at the power output end of the fifth driver 91 and fixedly connected to the slider 94, the mounting seat 96 is slidably connected to the second slide rail 71 and is driven to move by the seventh driver 72.

[0036] In one embodiment of the present invention, referring to Figure 4As shown, the mounting seat 96 is fixedly connected with a pressure sensor 92, and the pressure sensor 92 can abut between the mounting seat 96 and the slider 94, that is, the pressure sensor 92 and the slider 94 are separately arranged, and the slider 94 slides close to and abuts against the pressure sensor 92. When the spring suction nozzle 93 is repaired, there is no need to remove the pressure sensor 92, so as to avoid frequent adjustments to the position of the spring suction nozzle 93. The pressure sensor 92 is used to monitor the reaction force on the spring suction nozzle 93 so as to adjust the action of the fifth driver 91.

[0037] In one embodiment of the present invention, referring to Figure 3 As shown, the transfer area 11 is provided on the outer side of the frame 1, and the transfer area 11 is provided with a transfer plate for placing the workpiece, and the transfer area 11 is located at one end of the X-module 7. The X-module 7 can drive the material picking assembly 9 to move above the transfer area and then place the workpiece on the transfer plate.

[0038] In one embodiment of the present invention, referring to Figure 5 As shown, the clamping jaw assembly 8 includes a connecting plate 82, four clamping jaws 83 arranged on the connecting plate 82, and a clamping cylinder 81. The clamping cylinder 81 drives the four clamping jaws 83 to open or close to clamp the material tray.

[0039] The working principle of the automatic feeding device of the feeding bin of the utility model is:

[0040] The Y module 6 and the X module 7 move the material taking component 9 to the top of the first upper bin 3. After the CCD component 10 obtains the coordinates of the workpiece on the first full tray 2, the fifth driver 91 drives the suction component to descend and suction the workpiece. After the fifth driver 91 drives the suction component and the workpiece to rise to a predetermined height, the Y module 6 and the X module 7 move the material taking component 9 to the top of the transfer area 11, and the suction component places the workpiece on the transfer plate. This cycle is repeated until the first full tray 2 becomes an empty tray. At this time, the clamping claw component 8 clamps the empty tray and moves to the top of the lower bin 4 through the Y module 6 and places the empty tray on the second carrier. Then the first full tray lifting mechanism 3 1 continues to push the second full tray 2 up and continue to feed. When the first loading bin 3 is free of full trays 2, the Y module 6 and the X module 7 move the material taking component 9 to the top of the second loading bin 5 to continue taking materials. At this time, the first feeding mechanism 32 conveys the stacked full trays 2 to the first carrier 311 of the first loading bin 3, and the first full tray lifting mechanism 31 drives the first carrier 311 and the full trays 2 to rise and wait for feeding. When the lower bin 4 is full of empty trays, the second carrier descends and places the empty trays on the second conveyor belt. The empty tray transfer mechanism 42 transfers the empty trays to the loading area for reloading, and then the second carrier rises to continue receiving the empty trays.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
