Detailed implementation manners

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0034] Such as Figures 1 to 3As shown in the figure, the present utility model provides a tray discharging and conveying device 10, which includes a device frame 100, a discharging lifting mechanism 200 disposed within the device frame 100, a tray conveying mechanism 400 disposed on the device frame 100, and a tray grasping mechanism 300 disposed above the device frame 100. The discharging lifting mechanism 200 is used to discharge the trays stored within the device frame 100 to the top of the device frame 100. The tray grasping mechanism 300 is used to grasp and move the trays discharged to the top of the device frame 100 onto the tray conveying mechanism 400. The tray conveying mechanism 400 is used to carry and convey the trays so as to convey the trays and the flexible boards loaded thereon to other devices for inspection. In this way, when conveying trays without skirts, the tray grasping mechanism 300 can adsorb and grasp them and transfer them onto the tray conveying mechanism 400 for conveying, which can overcome the problem that the traditional clamping conveying device cannot clamp and convey the sides of trays without skirts, and has a wide adaptability.

[0035] Specifically, a storage chamber 102 is provided inside the device frame 100, and a discharging port 104 communicating with the storage chamber 102 is provided at the top of the device frame 100. The storage chamber 102 can be used to store multiple trays loaded with flexible boards. The discharging lifting mechanism 200 is disposed in the storage chamber 102 and corresponds to the discharging port 104 vertically. The tray conveying mechanism 400 is disposed on both sides of the discharging port 104 at the top of the device frame 100. The tray grasping mechanism 300 is disposed above the top of the device frame 100 and corresponds to the discharging port 104 vertically. The discharging lifting mechanism 200 can lift the trays in the storage chamber 102 to the discharging port 104. The tray grasping mechanism 300 grasps the trays located at the discharging port 104 and places them on the tray conveying mechanism 400. The tray conveying mechanism 400 can convey the received trays to other workstations. In addition, a device platform 110 can be provided at the top of the device frame 100, and both the tray conveying mechanism 400 and the tray grasping mechanism 300 can be disposed on the device platform 110.

[0036] Moreover, the discharging lifting mechanism 200 may include a lifting drive structure 210 disposed in the storage chamber 102 of the device frame 100, a lifting guide frame 220 extending vertically from the bottom wall of the storage chamber 102 to the discharging port 104, and a discharging lifting frame 230 connected to the lifting drive structure 210. The discharging lifting frame 230 is slidably disposed on the lifting guide frame 220. The trays in the storage chamber 102 can be stacked on the discharging lifting frame 230, or the trays can be placed at other positions or on other structures in the storage chamber 102, and the discharging lifting frame 230 can be used to obtain the trays. Then, the lifting drive structure 210 of the discharging lifting mechanism 200 can be used to lift the discharging lifting frame 230 with the obtained trays, so that the discharging lifting frame 230 rises along the lifting guide frame 220 to the discharging port 104 at the top of the device frame 100. That is, the lifting drive structure 210 of the discharging lifting mechanism 200 can drive the discharging lifting frame 230 to move up and down along the lifting guide frame 220, so that the skirtless trays stored in the storage chamber 102 can be lifted to the discharging port 104 by the discharging lifting frame 230.

[0037] Moreover, the tray grasping mechanism 300 may include a grasping support 310 protruding from the device platform 110 at the top of the device frame 100, a grasping drive structure 320 disposed on the grasping support 310, and an adsorption grasping plate 330 connected to the grasping drive structure 320. The adsorption grasping plate 330 corresponds to the discharging port 104 up and down. The grasping drive structure 320 of the tray grasping mechanism 300 can drive the adsorption grasping plate 330 to move, so that the adsorption grasping plate 330 adsorbs and grasps the skirtless trays lifted by the discharging lifting frame 230 to the discharging port 104. Then, the discharging lifting frame 230 descends and resets along the lifting guide frame 220 under the drive of the lifting drive structure 210, and the adsorption grasping plate 330 transfers the grasped skirtless trays to the tray conveying mechanism 400.

[0038] Moreover, the tray conveying mechanism 400 may include two track frame structures 410 disposed on the device platform 110 at the top of the device frame 100, one telescopic driving structure 420 respectively disposed on each of the two track frame structures 410, and a conveyor belt structure 430 connected to each telescopic driving structure 420. The two conveyor belt structures 430 are respectively located on both sides of the discharge port 104. After the tray grasping mechanism 300 grasps the skirtless tray sent out by the discharge lifting frame 230, the telescopic driving structure 420 of the tray conveying mechanism 400 can perform telescopic adjustment on the conveyor belt structures 430 on the two track frame structures 410 to keep an appropriate distance between the two conveyor belt structures 430. Then, the adsorption grasping plate 330 is driven by the material grasping driving structure 320 to place the grasped skirtless tray onto the two conveyor belt structures 430, so that both sides of the skirtless tray fall onto the two conveyor belt structures 430 respectively. Thus, the tray can be conveyed to the material detection mechanism by the two conveyor belt structures 430 to detect the flexible board in the tray.

[0039] In addition, as Figures 1 to 2 shown, in this embodiment, one storage chamber 102 may be provided on each of the inner sides of the device frame 100, and one discharge lifting mechanism 200 is provided in each storage chamber 102; moreover, one tray conveying mechanism 400 may be provided on each of the top sides of the device frame 100, one tray grasping mechanism 300 is correspondingly provided above each tray conveying mechanism 400, and each tray conveying mechanism 400 and one discharge lifting mechanism 200 are arranged in an up-and-down correspondence. That is, two sets of discharge lifting mechanisms 200, two sets of tray conveying mechanisms 400, and two sets of tray grasping mechanisms 300 can be simultaneously provided on one device frame 100 to simultaneously discharge and convey two trays, which can improve the discharge and conveying efficiency of the trays. Moreover, the two sets of discharge lifting mechanisms 200 are symmetrically arranged with respect to the horizontal center line (or vertical center line) of the device frame 100, the two sets of tray conveying mechanisms 400 are also symmetrically arranged with respect to the horizontal center line (or vertical center line) of the device frame 100, and the two sets of tray grasping mechanisms 300 are also symmetrically arranged with respect to the horizontal center line (or vertical center line) of the device frame 100.

[0040] In addition, only one storage chamber 102 may be provided inside the device frame 100, and one discharge lifting mechanism 200 is provided in the one storage chamber 102; moreover, one tray conveying mechanism 400 is provided on the top of the device frame 100, and one tray grasping mechanism 300 is correspondingly provided above the one tray conveying mechanism 400, and the one tray conveying mechanism 400 and one discharge lifting mechanism 200 are arranged in an up-and-down correspondence.

[0041] Furthermore, as Figures 3 to 5As shown in the figure, the material tray grasping mechanism 300 may include a first bracket 312 that protrudes horizontally from the device platform 110 at the top of the device frame 100, and a second bracket 314 that is vertically suspended from the top of the first bracket 312. The first bracket 312 is located outside the material tray conveying mechanism 400. By horizontally arranging the first bracket 312 of the material grasping bracket 310 at the top of the device frame 100, the space occupied by the material grasping bracket 310 at the top of the device frame 100 can be reduced. By suspending the second bracket 314 at the middle position of the first bracket 312, the suspended end of the second bracket 314 can protrude above the tops of the material tray conveying mechanism 400 and the discharging lifting mechanism 200, facilitating the material grasping and discharging of the adsorption material grasping plate 330 provided at the suspended end of the second bracket 314. Moreover, when two sets of material tray grasping mechanisms 300 are provided, a single first bracket 312 can be shared, with one first bracket 312 located at the middle position between the two material tray conveying mechanisms 400. Moreover, when two sets of material tray grasping mechanisms 300 are provided, the two second brackets 314 can be connected as a single unit and protrude from both sides of the first bracket 312 respectively, making the structure more stable.

[0042] Moreover, the material grasping drive structure 320 may include a material grasping lifting drive member 322 provided at the suspended end of the second bracket 314. The adsorption material grasping plate 330 is connected to the material grasping lifting drive member 322 and is arranged corresponding to the discharging lifting mechanism 200 up and down. By making the suspended end of the second bracket 314 located at the middle position above the material tray conveying mechanism 400 and the discharging lifting mechanism 200, and by setting the material grasping drive structure 320 at the suspended end of the second bracket 314 to only a lifting drive structure 210, the adsorption material grasping plate 330 can be directly driven to descend to the discharging port 104 to grasp and lift the skirtless material tray lifted by the discharging lifting frame 230 of the discharging lifting mechanism 200 to the discharging port 104, and lift the grasped skirtless material tray above the material tray conveying mechanism 400. After the two conveyor belt structures 430 of the material tray conveying mechanism 400 are adjusted to an appropriate distance, the grasped skirtless material tray is then lowered and placed on the two conveyor belt structures 430, and the skirtless material tray is conveyed by the two conveyor belt structures 430.

[0043] Further, the material-gripping lifting driving member 322 may include a material-gripping lifting seat 3222 connected to the suspended end of the second bracket 314, a material-gripping lifting driving cylinder 3224 provided on the material-gripping lifting seat 3222, a material-gripping lifting guiding frame 3226 movably provided on the material-gripping lifting seat 3222, and a material-gripping lifting plate 3228 connected to the driving end of the material-gripping lifting driving cylinder 3224. The material-gripping lifting guiding frame 3226 is connected to the top surface of the material-gripping lifting plate 3228, and the adsorption material-gripping plate 330 is connected to the bottom surface of the material-gripping lifting plate 3228. By providing the material-gripping lifting seat 3222 to connect the material-gripping lifting driving cylinder 3224 and guiding the material-gripping lifting plate 3228 through the material-gripping lifting guiding frame 3226, the lifting movement of the material-gripping lifting plate 3228 by the material-gripping lifting driving cylinder 3224 can be made more accurate and reliable, and the lifting movement of the adsorption material-gripping plate 330 by the material-gripping lifting plate 3228 can also be made more accurate and stable, so that the grasping and placing of the material tray by the adsorption material-gripping plate 330 are also more accurate and stable.

[0044] In addition, the material-gripping driving structure 320 may also include a planar movement driving structure provided on the second bracket 314, and the material-gripping lifting driving member 322 is provided on the planar movement driving structure. In this way, the adsorption material-gripping plate 330 can be horizontally moved through the planar movement driving structure, making the movement of the adsorption material-gripping plate 330 more flexible and the grasping and placing of the material tray more convenient. Moreover, the planar movement driving structure may include a horizontal transverse driving module provided on the second bracket 314 and a horizontal longitudinal driving module provided on the horizontal transverse driving module, and the material-gripping lifting driving member 322 may be provided on the horizontal longitudinal driving module. The horizontal transverse driving module and the horizontal longitudinal driving module may be set as a cylinder driving structure or a motor driving structure.

[0045] In addition, the adsorption material-gripping plate 330 may include a material-gripping main board connected to the material-gripping lifting driving member 322 and a plurality of material-gripping suction nozzles provided at the bottom of the material-gripping main board. The material tray can be adsorbed and grasped from multiple positions through the plurality of material-gripping suction nozzles.

[0046] In addition, as Figure 3 、 Figure 6 and Figure 7 shown, at least one of the two track frame structures 410 of the material tray conveying mechanism 400 is set as an adjustable track frame structure 410. By setting at least one of the track frame structures 410 as the adjustable track frame structure 410, the distance between the two track frame structures 410 can be adjusted, so that the distance between the two conveyor belt structures 430 can be adjusted, facilitating the conveying of material trays of different sizes.

[0047] Specifically, the adjustable track rack structure 410 may include two adjustment guide rails 412 arranged side by side longitudinally on the device platform 110 on the top surface of the device rack 100, a track rack base 414 slidably arranged on each adjustment guide rail 412, and a support track rack 416 connected transversely to the two track rack bases 414. The telescopic drive structure 420 is arranged on the support track rack 416. By slidably arranging the support track rack 416 of the adjustable track rack structure 410 on the device rack 100, the position of the support track rack 416 can be adjusted, so that the distance between the two track rack structures 410 can be adjusted.

[0048] Moreover, the adjustable track rack structure 410 may include a track rack drive structure arranged on the device platform 110 of the device rack 100. The track rack drive structure can be connected to the support track rack 416 or the track rack base 414 and is used to drive the support track rack 416 to slide along the adjustment guide rail 412. The track rack drive structure can be set as a motor drive structure, that is, the position of the support track rack 416 can be automatically adjusted by the track rack drive structure. In addition, the track rack drive structure can also be set as a manual adjustment structure, such as an adjustment handwheel structure with an adjustment screw rod that is threadedly connected to the support track rack 416 or the track rack base 414 of the adjustable track rack structure 410.

[0049] In addition, the adjustable track rack structure 410 may not be provided with a track rack drive structure, and the support track rack 416 can be slidably adjusted by manual pushing and pulling.

[0050] In addition, a track rack limit plate 418 is connected between the ends of the two track rack structures 410. At least one side of the track rack limit plate 418 is provided with a limit long groove, and the limit long groove corresponds to and cooperates with the end of the support track rack 416 of the adjustable track rack structure 410. By the track rack limit plate 418 connected between the ends of the two track rack structures 410, not only can the two be connected and fixed when the distance between the two track rack structures 410 does not need to be adjusted, but also the two conveyor belt structures 430 and the trays conveyed by them can be blocked and limited from the ends. Moreover, by providing a limit long groove on the end side of the track rack limit plate 418, the fixed position of the support track rack 416 and the track rack limit plate 418 can be flexibly adjusted when the position of the support track rack 416 of the adjustable track rack structure 410 is adjusted.

[0051] In addition, the telescopic driving structure 420 of the tray conveying mechanism 400 may include a telescopic bracket 422 protruding from the outside of the support track bracket 416 of the track bracket structure 410, one telescopic guide rail 424 arranged side by side on each of the two sides of the telescopic bracket 422, a telescopic driving frame 426 slidably arranged on the two telescopic guide rails 424, and a telescopic driving cylinder 428 arranged in the middle of the telescopic bracket 422. The telescopic driving cylinder 428 is connected to the telescopic driving frame 426, and the telescopic driving frame 426 is connected to the conveyor belt structure 430. By arranging the telescopic driving structure 420 on the outside of the support track bracket 416, the inner space of the support track bracket 416 is not occupied, so as not to affect the arrangement of the conveyor belt structure 430 inside the support track bracket 416 and the conveying of the trays.

[0052] Moreover, the telescopic driving cylinder 428 can drive the telescopic driving frame 426 to reciprocate along the telescopic bracket 422, and can drive the conveyor belt structure 430 connected to the telescopic driving frame 426 to move, so that the two conveyor belt structures 430 can approach or move away from each other. When it is necessary to grab the skirtless tray lifted by the discharging and lifting mechanism 200 from the discharging port 104 below the tray conveying mechanism 400 through the tray grabbing mechanism 300, the telescopic driving cylinder 428 can be used to drive the conveyor belt structures 430 to move away from each other, leaving a large gap between the two conveyor belt structures 430, so that the tray grabbing mechanism 300 can lift the skirtless tray above the conveyor belt structure 430; moreover, when it is necessary to place the grabbed skirtless tray on the conveyor belt structure 430 through the tray grabbing mechanism 300, the telescopic driving cylinder 428 can be used to drive the conveyor belt structures 430 to approach each other, which is convenient for placing the skirtless tray on the two conveyor belt structures 430 for conveying.

[0053] Furthermore, the telescopic driving frame 426 may include a telescopic frame base slidably arranged on each telescopic guide rail 424, a telescopic frame main board connected to the two telescopic frame bases, and a telescopic frame connecting board connected between the middle of the telescopic frame main board and the driving end of the telescopic driving cylinder 428. The telescopic frame main board and the telescopic driving cylinder 428 are respectively located on the upper and lower sides of the telescopic bracket 422, and the telescopic frame main board is connected to the conveyor belt structure 430. By arranging the telescopic frame main board and the telescopic driving cylinder 428 on the upper and lower sides of the telescopic bracket 422 respectively, the occupied space can be saved. Moreover, the telescopic frame main board is set as a long board structure, which can increase the connection area with the conveyor belt structure 430 and enhance the connection strength with the conveyor belt structure 430. Moreover, by connecting the telescopic frame main board with two telescopic frame bases, the driving of the telescopic frame main board and the conveyor belt structure 430 is more stable and reliable.

[0054] Moreover, the conveyor belt structure 430 may include a conveyor belt mounting plate 432 connected to the telescopic drive frame 426, a conveyor belt drive motor 434 disposed on the conveyor belt mounting plate 432, a conveyor belt wheel 436 rotatably disposed at each of the two ends inside the conveyor belt mounting plate 432, a conveyor belt 437 sleeved on the two conveyor belt wheels 436, and a conveyor belt limit plate 438 protruding from the top of the conveyor belt mounting plate 432. The drive end of the conveyor belt drive motor 434 is connected to one conveyor belt wheel 436, and the conveyor belt mounting plate 432 is located on the side of the discharge port 104. When conveying a skirtless tray through the two conveyor belt structures 430, first adjust the distance between the two conveyor belt structures 430 so that the two conveyor belts 437 maintain an appropriate distance, facilitating the placement of the skirtless tray grabbed by the tray grabbing mechanism 300 onto the two juxtaposed conveyor belts 437. Then, drive the conveyor belt wheel 436 to rotate through the conveyor belt drive motor 434, driving the conveyor belt 437 to operate, thereby driving the skirtless tray on the two conveyor belts 437 to move.
