Specific Embodiments

[0020] The following will clearly and completely describe the technical 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 of 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 shall fall within the protection scope of the present invention.

[0021] On the one hand, an embodiment of the present invention provides a non-stop feeding mechanism 100 for an automated assembly device 200, aiming to achieve the continuity and efficiency of product feeding, such as Figures 1 to 8b As shown, the non-stop feeding mechanism 100 includes a tray bin, and the tray bin includes a full tray bin 1 and an empty tray bin 2 arranged side by side. The full tray bin 1 is used to hold a tray 9 with a product 91 (which can be various products to be assembled, such as the temple of an AR glasses shown in the embodiment in the figure), and the empty tray bin 2 is used to hold the empty tray 9 after the product 91 is taken out; Above the side of the tray bin, there is a tray transfer mechanism 3, and a tray picking and placing mechanism 4 is provided on the tray transfer mechanism 3. The tray transfer mechanism 3 can carry the empty tray after the product is taken out from the full tray bin 1 to the empty tray bin 2 by means of the tray picking and placing mechanism 4.

[0022] During use, first, the tray 9 with the product 91 is placed in the full tray bin 1 to complete feeding. Then, after the product 91 is taken out, the tray picking and placing mechanism 4 holds the tray 9, and the tray transfer mechanism 3 transports the tray 9 from the full tray bin 1 to the empty tray bin 2 and places the empty tray 9 in the empty tray bin 2. Finally, the empty tray 9 in the empty tray bin 2 is taken out.

[0023] The non-stop feeding mechanism 100 of the present invention includes a tray bin. The tray bin includes a full-tray bin 1 and an empty-tray bin 2 arranged side by side. Through the dual-bin design of the full-tray bin 1 and the empty-tray bin 2, efficient management and recycling of the trays 9 are realized, meeting the flexibility requirements of modern production; above the side of the tray bin is provided with a tray transfer mechanism 3, and a tray picking and placing mechanism 4 is arranged on the tray transfer mechanism 3. The tray transfer mechanism 3 can, with the help of the tray picking and placing mechanism 4, carry the empty tray 9 after the products are emptied from the full-tray bin 1 to the empty-tray bin 2, thereby realizing the rapid transfer of the tray 9. In this way, after all the trays 9 in the full-tray bin 1 are transferred to the empty-tray bin 2, the tray 9 pre-loaded with products 91 can be placed into the full-tray bin 1 to achieve rapid feeding, without affecting the normal progress of subsequent processes. At the same time, all the empty trays 9 in the empty-tray bin 2 can be taken out to ensure the normal operation of this feeding mechanism. Thus, the present invention solves the deficiency that the feeding mechanism of the traditional automatic assembly equipment 200 needs to stop operation during the loading and unloading process, realizes the replacement of the tray during the operation of the equipment, thereby improving production efficiency and reducing potential safety hazards.

[0024] The tray transfer mechanism 3 is used to carry the empty tray 9 after the products are emptied from the full-tray bin 1 to one side of the empty-tray bin 2, realizing the rapid transfer of the tray 9. The tray transfer mechanism 3 can adopt various structural forms that are easily conceivable by those skilled in the art, such as conveyor belts, robotic arms, etc. For the convenience of implementation, in some embodiments of the invention, as Figures 2 to 3c shown, the tray transfer mechanism 3 can include a first horizontal slide rail 31 located above the rear sides of the full-tray bin 1 and the empty-tray bin 2. The tray picking and placing mechanism 4 is slidably connected to the first horizontal slide rail 31, and a first driving member (not shown) for driving the movement of the tray picking and placing mechanism 4 is provided on the first horizontal slide rail 31. The first driving member can be a servo motor, a cylinder, etc. In the embodiment shown in the figure, the tray transfer mechanism 3 is driven by a servo motor and is equipped with high-precision sensors (such as photoelectric sensors, etc.) to ensure the accuracy and efficiency of the transfer process.

[0025] The tray picking and placing mechanism 4 is used to pick and place trays. The tray picking and placing mechanism 4 can adopt various structural forms that are easily conceivable by those skilled in the art. For the convenience of implementation, in some embodiments of the invention, as Figures 2 to 3c shown, the tray picking and placing mechanism 4 can include an arm support 41 slidably connected to the first horizontal slide rail 31. A pair of arms 42 extending along the length direction of the tray and located on both sides of the tray are provided on the arm support 41. Suction cups (not shown) are provided on the lower surfaces of the pair of arms 42. In this way, the tray picking and placing mechanism 4 adopts a vacuum suction cup design to ensure the stability and reliability of the suction process, realizing precise positioning and rapid handling.

[0026] To improve work efficiency, a plurality of trays 9 can be placed vertically in the full tray bin 1. At this time, when all the products 91 in the full tray bin 1 are taken out, the tray retrieval mechanism 4 sucks the top tray 9 out of the full tray bin 1. A tray lifting mechanism 5 can be provided on the side of the full tray bin 1. The tray lifting mechanism 5 is used to lift all the trays 9 in the full tray bin 1 to a preset height when the top tray 9 in the full tray bin 1 is removed. In this way, multiple trays 9 can be placed in the full tray bin 1 at one time, improving work efficiency. The tray lifting mechanism 5 can also ensure that the top tray in the full tray bin 1 is always located at a pre-set material retrieval position, making it easier for the automated assembly equipment 200 to retrieve materials and for the tray transfer mechanism 3 and the tray retrieval mechanism 4 to move empty trays from the full tray bin 1 to the empty tray bin 2.

[0027] Similarly, multiple (empty) trays 9 can be placed vertically in the empty tray bin 2, and a tray lifting mechanism 5 can be provided on the side of the empty tray bin 2. The tray lifting mechanism 5 is used to lift all the trays 9 inside the empty tray bin 2 to a preset height when a tray 9 is placed in the top layer of the empty tray bin 2.

[0028] The tray lifting mechanism 5 is used to lift and elevate the tray 9 in the tray bin. The tray lifting mechanism 5 can adopt various structural forms that can be easily thought of by those skilled in the art. For the convenience of implementation, in some embodiments of the invention, such as Figures 2 to 3c 、 Figure 5b As shown, the tray lifting mechanism 5 can include a vertical slide rail 51 located on the side of the corresponding tray bin (specifically on the rear side), and the full tray bin 1 and the empty tray bin 2 are both provided with a tray base plate 11 slidably connected to the vertical slide rail 51 (located at the bottom of the full tray bin 1 and the empty tray bin 2 for supporting the tray 9), and the vertical slide rail 51 is provided with a second driving member 52 for driving the tray base plate 11 to move. The second driving member 52 can be a Z-axis electric cylinder, and the Z-axis electric cylinder can have a built-in high-precision sensor to monitor the position of the tray in real time to ensure the accuracy of the lifting and lowering actions.

[0029] Further, such as Figure 5b As shown, the four corners of the tray base 11 can be equipped with positioning posts 12 for positioning the trays 9. This allows for precise positioning of the trays 9 within the tray bin, facilitating workflows (such as clamping, placement, and handling). In practice, the positioning posts 12 can be four inward-facing right-angled posts. The trays in both the full tray bin 1 and the empty tray bin 2 can be stacked, with the preset height being the height of a single tray. This allows for maximum tray placement within a limited space, improving production efficiency.

[0030] In some embodiments of the invention, continue as Figures 2 to 3cAs shown in the figure, a tray clamping mechanism 6 can be provided in the full tray bin 1. The tray clamping mechanism 6 is used to clamp the tray 9 when taking materials from the full tray bin 1, preventing the tray 9 from shaking and shifting, and ensuring the stability and accuracy of the material taking process. The tray clamping mechanism 6 can adopt various structural forms that are easily conceivable by those skilled in the art. For the convenience of implementation, the tray clamping mechanism 6 can include a second horizontal slide rail 61 located at the upper end of the full tray bin 1, and a pair of clamping jaws 62 that are located on the opposite side of the tray in the full tray bin 1 and can move relatively. In the illustrated embodiment, the tray clamping mechanism 6 adopts a pneumatic clamping jaw design, which can adapt to trays of different sizes, and monitors the clamping force through a pressure sensor to avoid damage or deviation of the tray.

[0031] In summary, the present invention provides an efficient, safe and flexible non-stop feeding solution for automated assembly equipment, significantly improving production efficiency and operation safety. The present invention has the following beneficial effects: 1. Improve production efficiency: The non-stop operation significantly reduces the start-stop time of the equipment and improves the overall efficiency of the production line.

[0032] 2. Reduce safety hazards: It reduces the direct contact between operators and equipment, and reduces the safety risks caused by frequent start-stop of the equipment.

[0033] 3. Enhance equipment stability: The coordinated action of the tray clamping mechanism and the tray lifting mechanism ensures the stability and accuracy of the material taking and transfer processes.

[0034] 4. Flexibly adapt to production requirements: Through the dual-bin design of the full tray bin and the empty tray bin, efficient management and recycling of trays are realized, meeting the flexibility requirements of modern production.

[0035] On the other hand, an embodiment of the present invention provides a working method of the above non-stop feeding mechanism, as Figures 4 to 8b shown, including: Step S101: Pull out the full tray bin 1, place the tray 9 containing the product 91, and then push the full tray bin 1 back to its original position; This step corresponds to Figure 5a , Figure 5b , Figure 5c and Figure 5d , where Figure 5a and Figure 5b correspond to pulling out the full tray bin 1 and placing the tray 9 containing the product 91, Figure 5c and Figure 5d correspond to pushing the full tray bin 1 back to its original position.

[0036] In the embodiments of the present invention, both the full tray magazine 1 and the empty tray magazine 2 are of a drawer type structure in the automatic assembly equipment 200. In this way, loading outside the machine is realized: the tray magazine can be pulled out along the guide rail to the outside of the equipment. Through the pull-out design of the tray magazine, the operator can replace the tray 9 during the operation of the equipment, avoiding equipment downtime.

[0037] Step S102: The tray clamping mechanism 6 clamps the uppermost tray 9, and the equipment picks up materials until all the products 91 on the tray 9 are emptied. This step corresponds to Figure 6a and Figure 6b . In some embodiments of the invention, a handling module 8 may be provided above the full tray magazine 1 on the machine table 7 of the automatic assembly equipment 200. The handling module 8 is used to transport the products 91 in the full tray magazine 1 to the product conveyor belt. The handling module 8 and the tray clamping mechanism 6 cooperate to achieve automatic production, which is convenient to use. The handling module 8 can be a robotic arm to achieve precise positioning and rapid handling. The product conveyor belt may include Figure 4 the main line in Figure 4 . To improve production efficiency, it may also include

[0038] the return line in This step corresponds to Figure 7a and Figure 7b . Specifically, during implementation, the tray picking and placing mechanism 4 sucks the uppermost tray 9 away from the full tray magazine 1, and the tray lifting mechanism 5 in the full tray magazine 1 drives the tray bottom plate 11 to lift all the trays 9 inside by a tray height. The system automatically detects the tray position to ensure the accuracy of the lifting action; the tray lifting mechanism 5 in the empty tray magazine 2 drives the tray bottom plate 11 to lift all the trays 9 inside by a tray height. The tray transfer mechanism 3 transports the tray 9 to one side of the empty tray magazine 2 and places the empty tray 9 on the uppermost layer of the empty tray magazine 2. The system automatically detects the placement state of the empty tray 9 to ensure that it accurately falls into the designated position.

[0039] Step S104: Repeat steps S102 - S103 for the cyclic material picking and handling actions until all the products 91 are taken out, all the trays 9 are transferred to the empty tray magazine 2, the empty tray magazine 2 is pulled out, and all the empty trays 9 are taken out.

[0040] This step corresponds to Figure 8a and Figure 8b .

[0041] The working method of the non-stop feeding mechanism of the present invention solves the deficiency that the feeding mechanism of the traditional automated assembly equipment 200 needs to stop operation during the loading and unloading process, realizes the replacement of the tray during the operation of the equipment, thereby improving the production efficiency and reducing the safety hazards. The feeding link / tray replacement (putting the tray 9 loaded with the product 91 into the full-tray bin 1 and taking out the empty tray 9 in the empty-tray bin 2) can be completed within 1 minute, greatly improving the production efficiency.

[0042] On the other hand, an embodiment of the present invention provides an automated assembly equipment 200, such as Figure 1 and Figure 4 shown, including a machine table 7, and the above-mentioned non-stop feeding mechanism 100 is provided on the machine table 7.

The tray bin includes a full-tray bin 1 and an empty-tray bin 2 arranged side by side. Through the double-bin design of the full-tray bin 1 and the empty-tray bin 2, the efficient management and recycling of the tray 9 are realized, meeting the flexibility requirements of modern production; a tray transfer mechanism 3 is provided above the side of the tray bin, and a tray picking and placing mechanism 4 is provided on the tray transfer mechanism 3. The tray transfer mechanism 3 can carry the empty tray 9 after the product is emptied from the full-tray bin 1 to the empty-tray bin 2 by means of the tray picking and placing mechanism 4, thereby realizing the rapid transfer of the tray 9. In this way, after all the trays 9 in the full-tray bin 1 are transferred to the empty-tray bin 2, the tray 9 pre-loaded with the product 91 can be put into the full-tray bin 1 to realize rapid feeding without affecting the normal progress of the subsequent process.
