In the description of the present invention, it should be understood that if terms such as "top", "bottom", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0034] Please refer to Figures 1-6An embodiment of the present invention provides a novel tray lid separation mechanism, comprising a frame-type support frame 1, a first support plate 2 and a second support plate 3 arranged laterally on the support frame 1, a pulling component 4 for pulling a tray A arranged on the second support plate 3, a conveying component 5 for conveying the tray A arranged on the first support plate 2 and the second support plate 3, a blocking component 6 for blocking the tray A arranged on the first support plate 2 and the second support plate 3 respectively, a first pressing component 7 for pressing the bottom of the tray A arranged on the first support plate 2, a second pressing component 8 for pressing the bottom of the tray A arranged on the second support plate 3, a lifting component 9 arranged on the support frame 1 for moving multiple lid-removing pawl assemblies 10, multiple stacking pawl assemblies 11 arranged on the support frame 1 for storing lids B, and multiple lid-removing pawl assemblies 10 arranged on the lifting component 9. This system is used to separate lid B, which is mounted on a material tray A. After a process is completed, the material tray A needs to be separated from the lid B. Pulling component 4 pulls the material tray A into the production line, conveying component 5 conveys the material tray A to the lid picking position, blocking component 6 extends to block the material tray A, thereby positioning the material tray A at the lid picking position. First clamping component 7 and second clamping component 8 extend to clamp the bottom of the material tray A, lifting component 9 drives the lid picking pawl component 10 to descend and hook the lid B, then lifting component 9 drives the lid picking pawl component 10 to rise, thereby separating the lid B from the material tray A. Then the lid B continues to rise above the stacking pawl component 11, then lifting component 9 drives the lid B to descend, and the stacking pawl component 11 hooks the lid B to complete the stacking. The whole process is fast and reasonable, integrating feeding, separating lid B and storing lid B into one unit. It has a high degree of integration, compact structure, small space occupation, and short operation cycle.

[0035] like Figures 1-6 As shown, the pulling assembly 4 includes a pulling cylinder 401 detachably mounted on the second support plate 3, a connecting seat 402 detachably mounted on the output end of the pulling cylinder 401, and a pulling plate 403 detachably mounted on the upper end of the connecting seat 402. The connecting seat 402 is slidably connected to the second support plate 3. The pulling plate 403 has an upwardly bent portion at the end facing the material tray A. The pulling cylinder 401 drives the pulling plate 403 to move, pulling the material tray A into the production line. The connecting seat 402 is slidably connected to the second support plate 3 through a linear guide rail, ensuring good sliding stability.

[0036] like Figures 1-6As shown, the conveying assembly 5 includes a conveying rotary motor 501 detachably mounted on the first support plate 2, a rotating shaft 502 detachably connected to the conveying rotary motor 501, a first transmission wheel 503 mounted on the rotating shaft 502 near the first support plate 2, a second transmission wheel 504 mounted on the rotating shaft 502 near the second support plate 3, a third transmission wheel 505 rotatably mounted on the first support plate 2, a fourth transmission wheel 506 rotatably mounted on the second support plate 3, a first tensioning wheel 507 rotatably mounted on the first support plate 2, a second tensioning wheel 508 rotatably mounted on the second support plate 3, a first conveyor belt 509 mounted on the first transmission wheel 503, the third transmission wheel 505, and the first tensioning wheel 507, a second conveyor belt 510 mounted on the second transmission wheel 504, the fourth transmission wheel 506, and the second tensioning wheel 508, and a first support wheel 511 and a second support wheel 512 respectively fixedly mounted on both sides of the first tensioning wheel 507. The third support wheel 513 and the fourth support wheel 514 are fixedly set on both sides of the second tensioning wheel 508. The transmission rotary motor 501 drives the rotating shaft 502 to rotate. The rotating shaft 502 simultaneously drives the first transmission wheel 503 and the second transmission wheel 504 to rotate. The first transmission wheel 503 drives the first conveyor belt 509 to rotate and drives the third transmission wheel 505 to rotate. Similarly, the second transmission wheel 504 and the fourth transmission wheel 506 rotate, thereby conveying the material tray A. The first tensioning wheel 507 ensures the tension of the first conveyor belt 509 and provides support for the first conveyor belt 509 through the first support wheel 511 and the second support wheel 512, ensuring the conveying stability of the first conveyor belt 509. The second tensioning wheel 508 ensures the tension of the second conveyor belt 510 and provides support for the second conveyor belt 510 through the third support wheel 513 and the fourth support wheel 514, ensuring the conveying stability of the second conveyor belt 510. The entire conveying assembly 5 has an accurate conveying route and good conveying stability.

[0037] like Figures 1-6 As shown, the blocking assembly 6 includes a blocking cylinder 601 and a baffle 602 detachably mounted at the output end of the blocking cylinder 601. The baffle 602 on the first support plate 2 moves at the upper end of the first support plate 2, and the baffle 602 on the second support plate 3 moves at the upper end of the second support plate 3. The blocking cylinder 601 drives the baffle 602 to extend out of the blocking tray A, thereby positioning the tray A to the cover removal position, which is fast and accurate.

[0038] like Figures 1-6As shown, the first pressing assembly 7 includes a first pressing cylinder 701 and a first pressing plate 702 detachably disposed at the output end of the first pressing cylinder 701. The second pressing assembly 8 includes a second pressing cylinder 801 and a second pressing plate 802 detachably disposed at the output end of the second pressing cylinder 801. One end of the first pressing plate 702 passes through the first support plate 2, and one end of the second pressing plate 802 passes through the second support plate 3. The first pressing cylinder 701 drives the first pressing plate 702 to move towards the bottom of the tray A, and the second pressing cylinder 801 drives the second pressing plate 802 to move towards the bottom of the tray A. The first pressing plate 702 and the second pressing plate 802 press the bottom of the tray A tightly to prevent the tray A from rising along with the lid B when the lid is removed.

[0039] like Figures 1-6 As shown, the lifting assembly 9 includes a lifting cylinder 901 detachably mounted at the bottom of the support frame 1, and a lifting frame detachably mounted at the output end of the lifting cylinder 901. The lifting frame includes a lifting base plate 902, a first lifting support plate 903 and a second lifting support plate 904 vertically spaced on the upper surface of the lifting base plate 902, and a lifting upper plate 905 detachably mounted on the upper ends of the first lifting support plate 903 and the second lifting support plate 904. A cover-retrieving groove 9051 is vertically penetrating the lifting upper plate 905, and multiple cover-retrieving pawl assemblies 10 are arranged along the cover-retrieving groove 9051. The inner edge of 051 is set with the first support plate 2 and the second support plate 3 located between the first lifting support plate 903 and the second lifting support plate 904. The first support plate 2 is slidably connected to the first lifting support plate 903, and the second support plate 3 is slidably connected to the second lifting support plate 904. Specifically, there are 8 lid-removing pawls 1002. The lid-removing groove 9051 is rectangular and matches the shape of the lid B. Two lid-removing pawls 1002 are set on each edge of the lid, which makes the lid removal effect better and the lid B more stable during the lid removal process and less likely to fall off.

[0040] like Figures 1-6As shown, the cap-removing pawl assembly 10 includes a cap-removing fixing block 1001, a cap-removing pawl 1002 rotatably mounted on the cap-removing fixing block 1001, a first cover plate 1003 disposed on the end of the cap-removing fixing block 1001 opposite to the cap-removing pawl 1002, a cap-removing push block 1004 passing through the cap-removing fixing block 1001, a cap-removing spring 1005 disposed within the cap-removing push block 1004, and a cap-removing limiting screw 1006 passing through the cap-removing fixing block 1001. One end of the cap-removing spring 1005 abuts against the cap-removing push block 1004, and the other end of the cap-removing spring 1005 abuts against the inner wall of the first cover plate 1003. The cap-removing push block 1004 and the cap-removing pawl 1002... The lower end of the lid-removing pawl 1002 is provided with a straight hook-shaped first pawl part 10021. The lifting component 9 drives the lid-removing pawl 1002 to move upward. The lid B pushes the lid-removing pawl 1002 to rotate and pushes the lid-removing push block 1004 to compress the lid-removing spring 1005. When the lid B moves to the upper end of the first pawl part 10021, the lid-removing spring 1005 pushes the lid-removing pawl 1002 to rotate and reset due to the elastic force. The first pawl part 10021 hooks the lid B. Then the lifting component 9 rises to separate the lid B from the material tray A. In this way, the lid-removing pawl 1002 can automatically hook the lid B without manual operation. Compared with the gripper structure, it is not easy to damage the lid B.

[0041] like Figures 1-6As shown, the stacking pawl assembly 11 includes a stacking fixing block 1101, a stacking pawl 1102 rotatably mounted on the stacking fixing block 1101, a second cover plate disposed on the end of the stacking fixing block 1101 opposite to the stacking pawl 1102, a stacking push block passing through the stacking fixing block 1101, a stacking spring disposed within the stacking push block, and a stacking limiting screw passing through the stacking fixing block 1101. One end of the stacking spring abuts against the stacking push block, and the other end of the stacking spring abuts against the inner wall of the second cover plate. The stacking push block abuts against the stacking pawl 1102. The lower end of the stacking pawl 1102 is provided with a hook-shaped second pawl portion 11021. The stacking pawl assembly 11 is structurally similar to the cover removal pawl assembly 10, the main difference being that the vertical length of the stacking pawl 1102 is greater than the vertical length of the cover removal pawl 1002. It is worth noting that some components of the stacking pawl assembly 11 are not shown in the attached drawings. After the lid-removing pawl 1002 separates the lid B, it continues to rise. The lid B pushes the stacking pawl 1102 to rotate, and the stacking pawl 1102 pushes the stacking pusher block to compress the stacking spring. When the lid B moves above the second pawl part 11021, the stacking spring pushes the stacking pawl 1102 to reset due to the elastic force. The second pawl part 11021 hooks the lid B, and the lifting component 9 drives the lid-removing pawl 1002 to descend. The lid-removing pawl 1002 separates from the lid B, and the lid B stays on the stacking pawl 1102, that is, it is temporarily stored in the stacking trough 1001, waiting for subsequent manual or robotic arm collection of the lid B. Meanwhile, the material tray A is conveyed to other workstations through the conveying component 5. The stacking pawl component 11 has a simple structure and is easy to disassemble and assemble, realizing the automatic stacking and storage of the lid B.

[0042] like Figures 1-6 As shown, the support frame 1 includes a support upper plate 101, two support columns 102 detachably disposed on the lower surface of the support upper plate 101, and a support base plate 103 detachably disposed at the bottom of the two support columns 102. The overall structure is simple, lightweight, easy to disassemble and assemble, and allows observation of the working status of each component.

[0043] like Figures 1-6 As shown, a stacking trough 1001 is vertically oriented along the upper support plate 101. A limiting plate 12 is installed at each of the four corners of the stacking trough 1001. Four stacking pawl assemblies 11 are symmetrically arranged along the inner edge of the stacking trough 1001. The lid B is stored in the stacking trough 1001. During subsequent collection, improper collection methods may cause the lid B to collide with other components, potentially leading to deformation. The four limiting plates 12, working in conjunction with the lid B, provide a limiting and guiding function, preventing deformation when the lid B is removed. Furthermore, the limiting plates 12 are made of angle steel, and the limiting area formed by the four limiting plates 12 matches the shape of the lid B. Each limiting plate 12 corresponds to one corner of the lid B, resulting in a good limiting effect.
