[0022] The following will clearly and completely describe the solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0023] The present invention provides a disk feeding device. Refer to Figure 1 , the disk feeding device includes a frame 100. A transfer platform 200 is provided on the frame 100, a full-disk stacking device 300 located at one end of the transfer platform 200, an empty-disk stacking device 400 located below the full-disk stacking device 300, a disk picking device 500 for picking the bottom full disk from the full-disk stacking device 300, and a disk transferring device 600 for transferring the full disk on the disk picking device 500 to the transfer platform 200.

[0024] The disk feeding device in this embodiment feeds by transferring the disks 10 that are batch-loaded with workpieces. Refer to Figure 2 , the disk 10 can be a square disk. The disk 10 has a plurality of bins for placing workpieces. The peripheral side of the disk 10 has a clamping edge 10a extending outward. The types of workpieces can be various, such as electronic device wiring harnesses, etc., including but not limited to this. Specifically, refer to Figure 1 and Figure 3 , the present disk feeding device mainly consists of a frame 100, a transfer platform 200, a full-disk stacking device 300, an empty-disk stacking device 400, a disk picking device 500, and a disk transferring device 600. Among them, the frame 100 serves as the structural basis for installing other devices of the disk feeding device to achieve an integrated structural layout, and its frame shape is set according to actual situations.

[0025] The function of the full-disk stacking device 300 is to stack full disks. Multiple full disks loaded with workpieces are stacked on the full-disk stacking device 300 from bottom to top in sequence. The structural form of the full-disk stacking device 300 can be various. For example, the full-disk stacking device 300 includes two clamping blocks and a driving mechanism for driving the two clamping blocks to move towards or away from each other. The two clamping blocks are oppositely arranged along the two side directions of the transfer platform 200. The driving mechanism can be two driving cylinders provided corresponding to the two clamping blocks. The opposite surfaces of the two clamping blocks are provided with card slots adapted to the clamping edges of the disk. Driven by the two driving cylinders, the two clamping blocks move towards each other to extend and clamp the clamping edges 10a on the opposite sides of the disk 10, realizing the clamping of the full disk. Other full disks are stacked on the full disk clamped by the two clamping blocks.

[0026] The function of the tray taking device 500 is to take out the bottommost full tray from the full tray stacking device 300. The tray taking device 500 is located between the full tray stacking device 300 and the empty tray stacking device 400. The structural form of the tray taking device 500 can be various. For example, the tray taking device 500 includes two holding blocks and a driving mechanism for driving the two holding blocks to move towards or away from each other and up and down. The two holding blocks are arranged oppositely along both sides of the transfer platform 200 and avoid the positions of the two clamping blocks. The driving mechanism can adopt a conventional driving structure in the field, as long as it can drive the two holding blocks to move towards or away from each other and up and down, and will not be elaborated here too much. The tray taking process of the tray taking device is as follows: Driven by the driving mechanism, the two holding blocks reach below the bottommost full tray on the full tray stacking device 300 and hold it. Then the two clamping blocks retract, and the entire set of full trays is held by the two holding blocks. Subsequently, the two holding blocks move downwards so that the second full tray stacked on the bottommost full tray in the set of full trays reaches the clamping position of the two clamping blocks. The two clamping blocks move towards each other to extend and clamp the clamping edges 10a on the opposite sides of the second full tray. At this point, the two holding blocks continue to descend, and the bottommost full tray is immediately separated from the full trays above it, thereby realizing the taking out of the full tray at the bottom of the full tray stacking device 300.

[0027] The function of the tray transferring device 600 is to transfer the full tray taken out by the tray taking device 500 from the full tray stacking device 300 to the transfer platform 200. The structural form of the tray transferring device 600 can be various. For example, the tray transferring device 600 includes a pushing block and a driving mechanism. The driving mechanism can include a driving cylinder. The piston rod of the driving cylinder is horizontally arranged. The pushing block is connected to the piston rod of the driving cylinder. The pushing block is located on the opposite side of the tray taking device 500 relative to the transfer platform 200. After a full tray is taken on the tray taking device 500 and docked with the transfer platform 200, driven by the driving mechanism, the pushing block moves horizontally to push the tray on the tray transferring device 600 onto the transfer platform 200. Of course, the structural form of the tray transferring device 600 exemplified above is only exemplary, not restrictive, and can also be others.

[0028] The function of the transfer platform 200 is to receive the full tray and forwardly convey it to a preset position for loading workpieces, and to reversely convey the empty tray after loading. The structural form of the transfer platform 200 can be various, such as a conveyor belt, a transfer pallet, etc., including but not limited to this.

[0029] The function of the empty tray stacking device 400 is to stack empty trays. Multiple empty trays without loaded workpieces are stacked on the empty tray stacking device 400 in sequence from bottom to top. As for the structural form of the empty tray stacking device 400, it can be correspondingly set with reference to the structure of the full tray stacking device 300 described above, and will not be elaborated here. Among them, by stacking empty trays through the empty tray stacking device 400, it is convenient for batch recycling of empty trays.

[0030] The working principle of this tray loading equipment is as follows: The tray taking device 500 takes out the bottom full tray from the full tray stacking device 300, and the tray transferring device 600 transfers the full tray on the tray taking device 500 to the transfer platform 200. The transfer platform 200 forwards the full tray to a preset position for loading. After loading the workpieces, the transfer platform 200 reversely transfers the formed empty tray to the empty tray stacking device 400 for stacking, and thus the tray loading is realized in a cycle.

[0031] In the tray loading equipment of this embodiment, the trays 10 are stacked both before being fed in and after being fed out, and the stacking structures before and after being fed out are arranged vertically at the same end of the transfer platform 200. Compared with the prior art, it reduces the floor area and occupied space, reduces the use of the production site, and thus reduces the production cost.

[0032] In a preferred embodiment, referring to Figure 3 , the full tray stacking device 300 includes several supporting plates 310 for supporting the full trays and a first driving mechanism 320 for driving the supporting plates 310 to move horizontally. In this embodiment, several supporting plates 310 are arranged along the circumference of the full tray. The full tray stacking device 300 supports the edge of the full tray by surrounding it with several supporting plates 310 to realize the placement of the full tray, and other full trays are stacked on the full tray supported by the supporting plates 310 in sequence from bottom to top. Moreover, under the drive of the first driving mechanism 320, several supporting plates 310 can perform synchronous actions of extending or retracting to realize the supporting and releasing of the full trays stacked thereon. Specifically, the first driving mechanism 320 includes driving cylinders provided corresponding to each supporting plate 310. The cylinder body of the driving cylinder is fixed on the frame 100, and the supporting plate 310 is fixedly connected to the piston rod of the driving cylinder, and the driving cylinder is preferably a multi-rod cylinder. In actual setting, four supporting plates 310 are provided, and four driving cylinders are correspondingly provided. The four supporting plates 310 are pairwise opposite and are respectively arranged at the four corner positions of the full tray to jointly support the full tray. Of course, in addition to the form where each supporting plate 310 is independently configured with a cylinder as described above, the supporting plates 310 on the same side can also be set to be driven by the same driving cylinder, that is, using the same power source, to improve the synchronization degree of the actions of the supporting plates 310. The specific structure can be set according to the actual situation.

[0033] In a preferred embodiment, referring to Figure 3, the full tray stacking device 300 further includes a plurality of vertically arranged limiting frames 330, and the plurality of limiting frames 330 enclose a stacking space for stacking full trays. In this embodiment, the plurality of limiting frames 330 are arranged on the frame 100 and enclose a stacking space. The full trays on the pallet 310 are stacked one above the other in this stacking space. Under the limitation of the plurality of limiting frames 330, the full trays are stacked neatly, facilitating the tray taking operation of the tray taking device 500. Among them, the height of the limiting frame 330 is set according to the actual situation. In actual setting, the limiting frame 330 is L-shaped and there are four of them. The four limiting frames 330 correspond to the four corner positions of the full tray to realize the limitation of the full trays stacked on the pallet 310. Of course, the setting of the number and arrangement position of this limiting frame 330 is only exemplary and not restrictive.

[0034] In a preferred embodiment, referring to Figures 3 to 5 , the tray taking device 500 includes two relatively arranged chuck seats 510 and a second driving mechanism 520 for driving the chuck seats 510 to move. The chuck seats are provided with clamping grooves 511 for clamping the edges of the full trays. In this embodiment, the chuck seat 510 can be an integrally formed structure or assembled from multiple components. As for the second driving mechanism 520, its structural form can be set in various ways and will be described in detail in subsequent embodiments. Specifically, the two chuck seats 510 are respectively located in the area between two pallets 310 on the same side. The two chuck seats 510 of the tray taking device 500 can move horizontally towards or away from each other and vertically up and down under the drive of the second driving mechanism 520 to clamp the bottommost full tray of the full tray group stacked on the pallet 310, and cooperate with the movement of the pallet 310 to take out this full tray.

[0035] The specific process is as follows: driven by the second driving mechanism 520, the two clamping disc seats 510 successively perform synchronous rising and moving toward each other, and the clamping grooves 511 of the two clamp the opposite two sides of the bottom full disc of the full disc group (specifically, the clamping sides 10a mentioned above), and after clamping in place, the support plate 310 retracts under the drive of the first driving mechanism. At this time, the full disc group is temporarily placed due to the clamping of the bottom full disc by the two clamping disc seats 510, and then the two clamping disc seats 511 are moved to the bottom of the full disc group. 0 descends synchronously, and the full tray group moves downward as a whole, so that the second full tray stacked on the bottom full tray in the full tray group reaches the holding height of the support plate 310, and the support plate 310 extends under the drive of the first driving mechanism 320 to support the second full tray in the full tray group and the full tray stacked thereon, so far, the two clamping tray seats 510 continue to descend, and the bottom full tray is immediately separated from the full tray above it, so as to realize the removal of the bottom full tray on the full tray stacking device 300. After taking out the full material box, the two clamping tray seats 510 descend a certain height so that their clamping grooves 511 reach the height position of the conveying platform 200 and dock with the conveying platform 200, so that the tray moving device 600 can perform the tray moving operation.

[0036] Further, refer to Figure 5 The chuck seat 510 is also provided with a holding portion 512 located below the clamping groove 511 for receiving the empty tray transmitted from the conveying platform 200. In this embodiment, driven by the second driving mechanism 520, the two chuck seats 510, in the process of holding the full tray and descending, firstly make their holding portions 512 reach the height position of the conveying platform 200 and dock with the conveying platform 200, so as to jointly receive the empty tray transmitted from the conveying platform 200; then the two chuck seats 510 continue to descend, so that their clamping grooves 511 reach the height position of the conveying platform 200 and dock with the conveying platform 200, and after the tray moving device 600 moves the full trays held by the two chuck seats 510 onto the conveying platform 200, the two chuck seats 510 move horizontally in opposite directions, and the empty trays held by them will automatically detach and fall onto the empty tray stacking device 400 for stacking.

[0037] In a preferred embodiment, referring to Figure 4, the second driving mechanism 520 includes a lifting frame 521, a first driving assembly 522 for driving the lifting frame 521 to lift, and two second driving assemblies 523 disposed on the lifting frame 521 for driving the two chuck seats 510 to move towards or away from each other respectively. In this embodiment, the two chuck seats 510 can perform horizontal movement (including moving towards or away from each other) under the drive of the corresponding second driving assemblies 523; and under the lifting drive of the first driving assembly 522 on the lifting frame 521, they can perform vertical movement accordingly. Specifically, the lifting frame 521 is a U-shaped frame body, the first driving assembly 522 is disposed at the lower part of the lifting frame 521. The first driving assembly 521 includes a vertically arranged lead screw, a driving motor for driving the rotation of the lead screw of the lead screw, a vertically arranged guide post, and a guide rod inserted in the guide post. The lifting frame is fixedly connected to the nut seat of the lead screw and the guide rod respectively; the two second driving assemblies 523 are respectively disposed at both ends of the upper part of the lifting frame 521. The second driving assembly 523 includes a driving cylinder, the piston rod of the driving cylinder is horizontally arranged, the cylinder body of the driving cylinder is fixed on the lifting frame 521, and the chuck seat 510 is fixedly connected to the piston rod of the driving cylinder.

[0038] In a preferred embodiment, referring to Figure 3, the transfer platform 200 includes two conveyor belts 210 arranged in parallel and spaced apart. The tray transfer device 600 includes a hook member 610 located between the two conveyor belts 210 for hooking the full trays and a third driving mechanism 620 for driving the movement of the hook member 610. In this embodiment, the hook member 610 is a component with a hook portion at one end, which is connected to the output execution end of the third driving mechanism 620 and can move along the vertical direction and the horizontal direction respectively under the drive of the third driving mechanism 620. The structural form of the third driving mechanism 620 can be various. In this embodiment, the third driving mechanism 620 includes a linear guide rail, a synchronous pulley assembly, a driving motor for driving the operation of the synchronous pulley assembly, a mounting bracket connected to the slider of the linear guide rail, and a driving cylinder vertically arranged on the mounting bracket.

The synchronous belt of the synchronous pulley assembly is connected to the slider of the linear guide rail, and the piston rod of the driving cylinder is arranged vertically upward. That is, under the drive of the synchronous belt assembly and the driving cylinder, the hook member 610 can move along the horizontal conveying direction and the vertical direction of the transfer platform 200 respectively. Specifically, under the drive of the third driving mechanism 620, the hook member 610 can first move horizontally to the lower part of the full box taken out by the box taking device, then move upward to hook the full tray through its hook portion, and then move horizontally to drag it to the two conveyor belts 210 of the transfer platform 200. The opposite sides of the full tray are respectively placed on the two conveyor belts 210, and the transfer platform 200 synchronously operates through the two conveyor belts 210 to convey the full tray forward.

[0039] In a preferred embodiment, the tray loading device further includes a sensing device provided at the transfer platform 200 for sensing the full trays. In this embodiment, the function of the sensing device is to sense whether the tray transfer device 600 transfers and places the full trays onto the transfer platform 200. The sensing device is provided at one end of the transfer platform 200 where the full tray stacking device 300 and the empty tray stacking device 400 are located, that is, the tray inlet and outlet end. Preferably, the sensing device uses a proximity switch. When the sensing device senses that the tray transfer device 600 transfers and places the full trays onto the transfer platform 200, the transfer platform 200 starts to operate to convey the full trays.

[0040] In a preferred embodiment, referring to Figure 3, a positioning device 700 for positioning the full trays on the transfer platform 200 is further provided on the frame 100. The positioning device 700 includes fixed clamping plates 710 and movable clamping plates 720 oppositely arranged on both sides of the transfer platform 200, and a fourth driving mechanism 730 for driving the movable clamping plate 720 to move towards or away from the fixed clamping plate 710. In this embodiment, the positioning device 700 is arranged at the loading station of the transfer platform 200.

Among them, in order to facilitate the taking of the empty trays on the carrier, the structures such as the linear guide rail and the synchronous pulley assembly of the fifth driving mechanism 420 are arranged on the side close to the transfer platform 200 to optimize the structural layout.

[0042] Based on the tray loading device described in the above embodiments, it is easy to understand that according to its structural composition, it can also be used as a tray unloading device. Specifically, the functions of its full tray stacking device 300 and empty tray stacking device 400 are interchanged, and are respectively used for stacking empty trays and full trays. That is, the tray taking device 500 takes out the bottom empty tray from the empty tray stacking device 400 (now the full tray stacking device 300), and the tray transferring device 600 transfers the empty tray on the tray taking device 500 to the transfer platform 200. The transfer platform 200 transfers the empty tray forward to a preset position for unloading. After the workpiece is unloaded into the empty tray, the transfer platform 200 transfers the formed full tray backward to the full tray stacking device 300 (now the empty tray stacking device 400) for stacking, and the cycle work is carried out to achieve unloading. In addition, it can also be used as a tray loading and unloading device, that is, after taking out the unprocessed workpiece in the full tray on the transfer platform 200 for loading, at the same time, the processed workpiece is placed on the full tray for unloading.
