[0031] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following will describe the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term “and / or” used herein includes any and all combinations of one or more of the related listed items.

[0033] Please refer to Figures 1 to 7, an embodiment of the present application provides a feeding device 100 for a tray with a cover plate. The feeding device 100 for a tray with a cover plate includes a tray handling mechanism 1, a cover plate picking and placing mechanism 2, and a feeding mechanism 3. Among them, the tray handling mechanism 1 includes a frame 11 and a handling component. The frame 11 is sequentially provided with a loading position 111, a feeding position 112, and a discharging position 113 along the first direction X. The handling component is slidably connected to the frame 11 along the first direction X, and the handling component is used to transport the full tray 61 with a cover plate from the loading position 111 to the feeding position 112, and to transport the empty tray 61 with a cover plate from the feeding position 112 to the discharging position 113. The cover plate picking and placing mechanism 2 is disposed above the feeding position 112 of the frame 11. The cover plate picking and placing mechanism 2 is used to pick and place the cover plate 62 on the tray 61 located at the feeding position 112. The feeding mechanism 3 is disposed below the feeding position 112 of the frame 11. The feeding mechanism 3 includes a linear module 31 disposed along the second direction Y. A first suction cup assembly 32 is provided at the moving end of the linear module 31. When the cover plate picking and placing mechanism 2 picks the cover plate 62, the first suction cup assembly 32 sucks the material from the bottom of the tray 61. Among them, the second direction Y and the first direction X are arranged horizontally and perpendicular to each other.

[0034] The feeding device 100 for a tray with a cover plate provided by the embodiment of the present application includes a tray handling mechanism 1, a cover plate picking and placing mechanism 2, and a feeding mechanism 3. Among them, the tray handling mechanism 1 transports the full tray 61 with a cover plate from the loading position 111 to the feeding mechanism 3 at the feeding position 112. The first suction cup assembly 32 sucks the material in the tray 61. The cover plate picking and placing mechanism 2 takes away the cover plate 62. The feeding mechanism 3 feeds the full tray 61 without a cover plate 62. After the feeding is completed, the feeding mechanism 3 retrieves the empty tray 61 without a cover plate 62. The cover plate picking and placing mechanism 2 then places the cover plate 62 back. Finally, the tray handling mechanism 1 transports the empty tray 61 with a cover plate 62 to the discharging position 113. By automatically picking and placing the cover plate 62 through the cover plate picking and placing mechanism 2, the labor intensity of manual work is reduced, and the automation operation efficiency is improved. By fixing the material in the tray 61 through the first suction cup assembly 32, the effect of the cover plate picking and placing mechanism 2 picking the cover plate is improved.

[0035] In a feasible implementation manner, as Figures 1 to 3 shown, the feeding device 100 for a tray with a cover plate further includes: a loading mechanism 4 and a discharging mechanism 5. Among them, the loading mechanism 4 is disposed below the loading position 111 of the frame 11 and is used to convey the full tray 61 with a cover plate to the loading position 111 of the frame 11. The discharging mechanism 5 is disposed below the discharging position 113 of the frame 11 and is used to remove the empty tray 61 with a cover plate at the discharging position 113 of the frame 11.

[0036] In a feasible implementation, the cover-plate material tray feeding device 100 can also be combined with other loading and unloading structures different from the aforementioned loading and unloading mechanism 5. For example, it can be a loading and unloading streamline. The full-cover material tray 61 is transported to the loading position 111 through the streamline components, and then the empty cover-plate material tray 61 is removed from the unloading position 113 through the streamline components. Another example is that the full-cover material tray 61 can be loaded onto the loading position 111 through components such as a manipulator, and then the empty cover-plate material tray 61 at the unloading position 113 can be unloaded through the manipulator components.

[0037] In a feasible implementation, as Figures 1 to 4 shown, the handling component includes two handling units 12. One of the handling units 12 is used to transport the full-cover material tray 61 from the loading position 111 to the feeding position 112. The other handling unit 12 is used to transport the empty cover-plate material tray 61 from the feeding position 112 to the unloading position 113. Each handling unit 12 includes a first driving component 121 and two pairs of gripper components 122 arranged in pairs. The fixed end of the first driving component 121 is slidably connected to the frame 11 along the first direction X. The output end of the first driving component 121 is connected to the two gripper components 122. The first driving component 121 is used to drive the two gripper components 122 to move in the vertical direction. Each gripper component 122 includes a gripper 1221 and a second driving component 1222. The second driving component 1222 is used to drive the two grippers 1221 to approach or separate from each other to grip or release the material tray 61.

[0038] In a feasible implementation, as Figures 1 to 4 shown, each handling unit 12 further includes a second back plate 123. The second back plate 123 is fixedly connected to the output end of the first driving component 121. The two gripper components 122 are fixedly connected to the output end of the first driving component 121 through the second back plate 123. The second back plate 123 is also fixedly provided with a pair of positioning pin columns 124. The positioning pin columns 124 are used to position the material tray 61.

[0039] In a feasible implementation, as Figures 1 to 4As shown in the figure, two of the handling units 12 are fixedly connected along the first direction X through a first back plate 13. The first back plate 13 is slidably connected to the frame 11 along the first direction X. By providing the first back plate 13, the two handling units 12 can be moved synchronously. In this way, when one handling unit 12 is at the loading position 111, the other handling unit 12 is at the feeding position 112, or when one handling unit 12 is at the feeding position 112, the other handling unit 12 is at the unloading position 113, enabling synchronous loading and feeding or synchronous feeding and unloading. This can simplify the equipment structure, reduce costs, and save energy consumption.

[0040] As Figures 1 to 4 shown in the figure, the handling assembly is slidably connected to the frame 11 through a sixth driving assembly 14. The sixth driving assembly 14 includes a sixth motor, a sixth coupling, a sixth lead screw, and a sixth moving plate. The fixed end of the sixth motor is fixedly connected to the frame 11. The sixth coupling fixedly connects the sixth lead screw to the output end of the sixth motor. The sixth moving plate is fixedly connected to the end of the sixth lead screw away from the sixth motor. The first back plate 13 is fixedly connected to the sixth moving plate.

[0041] A first sliding assembly 15 is further provided on the frame 11. The first sliding assembly 15 includes a first slide rail and a first slider. The first slide rail is arranged along the first direction X, and the first back plate 13 is fixedly connected to the first slider. In this way, by providing the first sliding assembly 15, the sliding assembly can bear a certain load and stably support an object. The sliding assembly can ensure that the object moves smoothly and smoothly along a predetermined direction. The sliding assembly can also improve the accuracy and stability of the object movement. The sliding assembly can also provide precise positioning ability. At the same time, the sliding assembly is usually made of wear-resistant materials and has a long service life. The sliding assembly can prevent the object from accidentally falling off during the movement. The sliding assembly can also be provided with a locking function to fix the object at a certain position and increase safety.

[0042] In a feasible implementation manner, as Figures 1 to 5 shown in the figure, the cover plate picking and placing mechanism 2 includes a third driving assembly 21. The fixed end of the third driving assembly 21 is fixedly connected to the frame 11. The output end of the third driving assembly 21 is provided with a second suction cup assembly 22. The third driving assembly 21 is used to drive the second suction cup assembly 22 to reciprocate vertically. The second suction cup assembly 22 is connected to an air circuit assembly. The second suction cup assembly 22 is used to suck the cover plate 62 on the tray 61. Specifically, the third driving assembly 21 can be a cylinder. The second suction cup assembly 22 is driven by the cylinder to suck the cover plate 62.

[0043] Furthermore, a floating joint 24 may be provided at the output end of the third driving assembly 21. The floating joint 24 is also known as a floating coupling or a floating connecting member. During actual installation, it is very difficult to achieve perfect alignment. The floating joint 24 can compensate for these installation errors and reduce the resulting stress. Even in the case of slight misalignment, the floating joint 24 can ensure the normal operation of the cylinder. By allowing a certain degree of offset, the floating joint 24 can reduce the stress between the cylinder rod and the connecting member. Wear is reduced, thereby extending the service life of the cylinder and its related components. The floating joint 24 can reduce the vibration caused by misalignment, thereby improving the overall accuracy of the system. Reducing vibration also helps to reduce the noise level during operation. By reducing wear and stress, the floating joint 24 helps to reduce the likelihood of failures. Due to the reduced wear, the floating joint 24 can reduce the number of maintenance times and maintenance costs. The floating joint 24 simplifies the installation process and does not require strict alignment adjustment. Since the installation process is simpler, installation time and costs can be saved. In an environment with large temperature variations, the floating joint 24 can compensate for the dimensional changes caused by thermal expansion and contraction. In applications with frequent load changes, the floating joint 24 can adapt to different load conditions. The floating joint 24 enables the cylinder to better adapt to various applications, increasing the flexibility of the system. The floating joint 24 can reduce the impact between the cylinder rod and the connecting member, making the power transmission smoother. Further, the floating joint 24 usually has various designs to adapt to different application requirements, including but not limited to: spherical floating joint 24: allowing a certain degree of rotation and tilt; cross floating joint 24: suitable for applications requiring larger angular deviations; elastic floating joint 24: absorbing deviations through elastic elements and suitable for light load applications; hinge-type floating joint 24: suitable for applications with large angular deviations.

[0044] In a feasible implementation manner, as Figures 1 to 5 shown, the cover plate picking and placing mechanism 2 further includes a first guiding assembly 23 and a first buffering assembly. The first guiding assembly 23 is used to guide the output direction of the third driving assembly 21, and the first buffering assembly is used to buffer the contact between the second suction cup assembly 22 and the cover plate.

[0045] Furthermore, the first guiding assembly 23 includes: a first mounting plate 231, a second mounting plate 232, a guiding rod 233, and a guiding cylinder 234. The first mounting plate 231 is fixedly connected to the floating joint 24. The guiding cylinder 234 is fixedly connected to the first mounting plate 231 and the second mounting plate 232. The guiding rod 233 is sleeved inside the guiding cylinder 234, and one end of the guiding rod 233 is fixedly connected to the second mounting plate 232, and the other end of the guiding rod 233 is detachably connected with a limit cap.

[0046] In a feasible implementation manner, asFigures 1 to 7 As shown, the loading mechanism 4 includes a fourth driving component. The output end of the fourth driving component is fixed with a loading platform 42. The loading platform 42 is used to carry the full-capacity tray 61 with a cover plate, and the fourth driving component is used to drive the loading platform 42 to move upward in the vertical direction. Specifically, the fourth driving component includes a fourth motor 411, a fourth coupling, a fourth lead screw 412, and a fourth moving plate 413. The fourth coupling fixedly connects the fourth lead screw 412 to the output end of the fourth motor 411. The fourth moving plate 413 is fixedly connected to the end of the fourth lead screw 412 away from the fourth motor 411. The loading platform 42 is fixedly connected to the fourth moving plate 413. Further, the first driving component 121 further includes a fourth fixing plate 414. The fourth fixing plate 414 is fixedly connected to the fixed end of the fourth motor 411. A tray 61 detector 415 and a position inductor are provided on the fourth fixing plate 414. The tray 61 detector 415 is used to detect whether the loading platform 42 carries a tray 61. The position inductor is used to detect whether the tray 61 on the loading platform 42 is in place.

[0047] In a feasible implementation, as Figure 1 and Figure 7 shown, the unloading mechanism 5 includes a fifth driving component. The output end of the fifth driving component is fixed with an unloading platform. The unloading platform is used to carry the empty tray 61 with a cover plate, and the fifth driving component is used to drive the unloading platform to move downward in the vertical direction. The structure of the unloading mechanism 5 can be the same as or similar to that of the loading mechanism 4, which will not be elaborated here.
