[0028] 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. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0029] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, 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, and therefore should not be construed as a limitation on the scope of protection of this invention. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0030] like Figures 1 to 17As shown, the automatic loading and unloading equipment for the tumbling mill of the present invention includes: an actively rotating assembly / disassembly turntable 1, a first drive motor connected to the assembly / disassembly turntable 1 to drive its active rotation, an assembly / disassembly fixture 2 detachably mounted on the assembly / disassembly turntable 1, and the periphery of the assembly / disassembly turntable 1 is provided with: a component one loading unit 3: placing component one into the assembly / disassembly fixture 2; a product loading unit 4: placing the product on component one; a component two loading unit 5: placing component two on the product to form an assembly; a transfer unit 6: transferring the assembly between storage fixtures 65; a component two unloading unit 7: removing component two from the assembly; and a component one unloading unit 8: removing component one from the assembly / disassembly fixture 2.

[0031] Component 1 is a base, and component 2 is a cover. Both components 1 and 2 have a central through hole 11. Component 1 has a slot 12. Component 1 has a flange 13 in the middle, and component 2 has a flange 14 in the middle. The central through hole 11 is respectively located on flange 13 and flange 14. Flange 14 is conical in shape. Under pressure, flange 14 can be assembled into flange 13 from top to bottom. Under thrust, force is applied from bottom to top, which can separate flange 14 from flange 13, allowing the product to contact the base and cover. When flange 14 is assembled into flange 13, components 1 and 2 apply force from top to bottom to fix the product, thereby allowing the sides of the product to be rolled.

[0032] In one embodiment, the product is the case of an electronic watch.

[0033] The assembly / disassembly fixture 2 includes: a fixed plate 21 detachably mounted on the assembly / disassembly turntable 1; a sliding member 22 sliding on the fixed plate 21; an abutment plate 23 fixedly connected to the sliding member 22; a contact plate 24 fixedly connected to the sliding member 22; and an elastic member with one end in contact with the fixed plate 21 and the other end in contact with the contact plate 24. The fixed plate 21 has a sliding groove 25, and the sliding member 22 slides within the sliding groove 25. The sliding member 22 has a contour hole 26 and a locking edge 27 that can slide within the slot 12 of component one. When the abutment plate 23 abuts against the fixed plate 21, the elastic member continuously applies elastic force to the contact plate 24. At this time, the locking edge 27 is locked within the sliding groove 25, locking component one and preventing component one from detaching from the fixed plate 21.

[0034] In one application scenario, the assembly / disassembly turntable 1 is provided with an insertion hole, and a positioning rod is fixedly installed on the fixing plate 21. The positioning rod is inserted into the insertion hole from top to bottom to separate it from the assembly / disassembly turntable 1. That is to say, when it is necessary to process the assembly, the assembly / disassembly fixture 2 can be pulled out directly upwards.

[0035] In practical use, the assembly / disassembly fixture 2 needs to be used with an opening cylinder. The opening cylinder pushes the abutment plate 23, which compresses the elastic element and moves the sliding element 22, causing the locking edge 27 to disengage from the sliding groove 25, so that the assembly or component can be taken out or put in.

[0036] In this application, the fixing plate 21 has eight contour holes 26 arranged in two rows and four columns.

[0037] The component feeding unit 3 includes: a first linear module 31 and a first gripper 32 mounted on the first linear module 31; the component is fed by a vibratory feeder, the first linear module 31 drives the first gripper 32 to move, and the first gripper 32 sequentially clamps 8 components and places them in the contour hole 26.

[0038] Product loading unit 4 includes: a first robotic arm 41; multiple material frame lifting mechanisms 42; a material frame fixing mechanism 43 corresponding to the number of material frame lifting mechanisms 42; and a material frame transfer mechanism 44. The first robotic arm 41 is equipped with a clamp 45 for gripping products. Each material frame lifting mechanism 42 includes a servo motor 46, a ball screw 47, and a guide rail 48. The servo motor 46 is connected to the ball screw 47, and the material frame carrier plate is connected to the ball screw 47 and the guide rail 48. When the servo motor 46 rotates, it drives the material frame carrier plate to move via the ball screw 47. The material frame fixing mechanism 43 includes a fixing cylinder 49 and a clamping member 410 mounted on the piston rod of the fixing cylinder 49. The cylinder 49 has two sides, which drive the clamping member 410 to move towards the middle from the sides, thereby fixing the loading tray; the material frame transfer mechanism 44 includes: an eighth linear module 411, a lifting slide cylinder 412 fixedly installed on the eighth linear module 411, a clamping plate 413 installed on the piston rod of the lifting slide cylinder 412, a clamping frame cylinder 414 fixedly installed at both ends of the clamping plate 413, and a clamping plate 415 installed on the piston rod of the clamping frame cylinder 414. The eighth linear module 411 can drive the lifting slide cylinder 412 to move, the lifting slide cylinder 412 can drive the clamping plate 413 to move, and the clamping frame cylinder 414 synchronously drives the clamping plate 415 to move to clamp the material frame.

[0039] In this application, the first robotic arm 41 is used for loading and unloading. Therefore, three sets of material frame lifting mechanisms 42 are provided, one for loading, another for unloading, and the third for buffering the material frame. The material frame fixing mechanism 43 fixes the uppermost material frame of the material frame lifting mechanism 42, that is, it performs centering, positioning and clamping. The material frame transfer mechanism 44 transfers the material frame between the three sets of material frame lifting mechanisms 42.

[0040] The component two feeding unit 5 includes at least: a second linear module 51 and a second gripper 52 mounted on the second linear module 51; the component two is fed by a vibratory feeder, the second linear module 51 drives the second gripper 52 to move, and the second gripper 52 sequentially clamps 8 components two and places them on the component one.

[0041] In actual use, since components one and two are fed by a vibratory feeder, and components one and two are arranged relatively densely when the vibratory feeder is feeding, the first gripper 32 and the second gripper 52 need to grip multiple components at once. Therefore, a material distribution component 53 is provided on the periphery of the assembly turntable 1 to distribute components one or two, so that the first gripper 32 or the second gripper 52 can pick up the materials. Its main function is to arrange components one and two at a certain interval.

[0042] The material distribution component 53 includes a seventh linear module 501 and a material distribution plate 502 mounted on the seventh linear module 501. The material distribution plate 502 is provided with a plurality of storage cavities 503. The material distribution component 53 is located at the feeding point of the vibratory feeder. Component one or component two is fed into a storage cavity 503. Then, the seventh linear module 501 drives the material distribution plate 502 to move, so that component one or component two is fed into an adjacent storage cavity 503. This achieves the purpose of arranging component one and component two at a certain interval, which facilitates the first gripper 32 and the second gripper 52 to pick up the material.

[0043] After the component two feeding unit 5 assembles into a composite part, the pressure holding unit 54 applies pressure to the composite part to assemble flange two 14 into flange one 13. The pressure holding unit 54 includes: a pressure holding cylinder 504; a pressure holding head 505 installed on the piston rod of the pressure holding cylinder 504; a support plate 506; and a support cylinder 507 that moves the support plate 506 toward the pressure holding head 505. The pressure holding cylinder 504 moves the pressure holding head 505 downward, and the support cylinder 507 moves the support plate 506 upward. A lifting plate is fixedly installed on the pressure holding head 505. When the composite part is between the lifting plate and the support plate 506, force is continued to be applied so that flange two 14 is assembled into flange one 13.

[0044] After the pressure holding unit 54 has finished holding the pressure on the assembly, the material handling mechanism 71 removes the assembly from the assembly / disassembly fixture 2. The material handling mechanism 71 includes: an assembly moving module 711, an assembly lowering cylinder 712, and an assembly material handling gripper 713. The assembly moving module 711 drives the assembly lowering cylinder 712 to move, and the assembly lowering cylinder 712 drives the assembly material handling gripper 713 to rise and fall. The assembly material handling gripper 713 is used to grip the assembly.

[0045] The transfer unit 6 includes: a second robotic arm 61, a transfer turntable 62 that can be actively rotated, an assembly auxiliary unloading component 63, and an assembly auxiliary loading component 64. A storage fixture 65 is detachably installed on the transfer turntable 62. In this application, a second drive motor is connected to the transfer turntable 62 to drive it to rotate actively. The transfer turntable 62 has four stations, namely a loading and unloading station, a loading station, and an unloading station.

[0046] At the loading and unloading station, the worker removes the storage fixture 65, which is full of assemblies, and installs it into the tumbling mill, or places the storage fixture 65, which has been processed by the tumbling mill, onto the transfer turntable 62 to realize the loading or unloading of the storage fixture 65.

[0047] When an assembly is required, the transfer turntable 62 rotates, causing the empty storage fixture 65 to rotate to the loading station. The assembly auxiliary loading component 64 assists the second robot arm 61 in loading the assembly onto the storage fixture 65.

[0048] When it is necessary to unload the assembly, the transfer turntable 62 rotates, causing the storage fixture 65 to rotate to the unloading station, and the assembly auxiliary unloading component 63 assists the second robot arm 61 to unload the assembly onto the assembly / disassembly fixture 2.

[0049] It is not difficult to see from the above description that the second robotic arm 61 should be provided in two parts, one for loading and the other for unloading.

[0050] The storage fixture 65 includes at least a hanging rod 651, with the middle part of the assembly passing through the hanging rod 651. The assembly auxiliary unloading component 63 pushes the assembly upward to move it away from the hanging rod 651, and the assembly auxiliary loading component 64 clamps the hanging rod 651.

[0051] The component two unloading unit 7 and the component one unloading unit 8 can be set as needed. In one embodiment, the component two unloading unit 7 includes: a lifting cylinder 661, a lifting plate 662 fixedly installed on the piston rod of the lifting cylinder 661, and a plurality of ejector pins 663 fixedly installed on the lifting plate 662. In this application, there are eight ejector pins 663. The lifting cylinder 661 drives the lifting plate 662 to move, so that the ejector pins 663 are inserted into the assembly and continue to apply a thrust, so that the flange two 14 is separated from the flange one 13.

[0052] The component feeding unit 8 includes: a first picking cylinder 508; a second picking cylinder 509 is mounted on the first picking cylinder 508, and a third picking cylinder 510 is mounted on the piston rod of the second picking cylinder 509; the first picking cylinder 508 is a rodless cylinder, and the first picking cylinder 508 drives the second picking cylinder 509 to move laterally; the second picking cylinder 509 drives the third picking cylinder 510 to move up and down, and the third picking cylinder 510 is a pneumatic gripper, and the third picking cylinder 510 is used to grip the first assembly.

[0053] The assembly auxiliary unloading component 63 includes: a fifth linear module 631; a first lifting plate 632: fixedly installed on the moving part of the fifth linear module 631; a first pushing cylinder 633: fixedly installed on the first lifting plate 632; a unloading plate 634 is connected to the piston rod of the first pushing cylinder 633, and the unloading plate 634 has a lifting hole 635 for lifting the assembly from the hanging rod 651.

[0054] In actual use, the fifth linear module 631 drives the first lifting plate 632 to move upward, and then the first pushing cylinder 633 drives the unloading plate 634 to move towards the hanging rod 651, so that the unloading plate 634 is inserted between adjacent assemblies, and the lifting hole 635 contacts the hanging rod 651. Then, the fifth linear module 631 drives the first lifting plate 632 to move upward. At this time, since the lifting hole 635 contacts the hanging rod 651, the unloading plate 634 moves upward, so that the assembly is disengaged from the hanging rod 651, making it convenient for the second robotic arm 61 to pick up the material.

[0055] The auxiliary feeding assembly 64 includes: a sixth linear module 641; a second lifting plate 642 fixedly mounted on the moving part of the sixth linear module 641; a second pushing cylinder 643 fixedly mounted on the second lifting plate 642; a first clamping plate 644 connected to the piston rod of the second pushing cylinder 643; a third pushing cylinder 645 fixedly mounted on the first clamping plate 644; a second clamping plate 646 connected to the piston rod of the third pushing cylinder 645; and half holes 647 for clamping the hanging rod 651 after combination on the first clamping plate 644 and the second clamping plate 646.

[0056] In actual use, the sixth linear module 641 drives the second lifting plate 642 to move to the highest position. Then, the second push cylinder 643 pushes the first clamping plate 644 to move so that the half hole 647 is above the hanging rod 651. Then, the sixth linear module 641 drives the second lifting plate 642 to move to a suitable position. Next, the third push cylinder 645 drives the second clamping plate 646 to move, thereby fixing the hanging rod 651. When fixing is not required, the third push cylinder 645 drives the second clamping plate 646 to move in the opposite direction so that the second clamping plate 646 is away from the hanging rod 651, providing a suitable position for the second clamping plate 646 to move. Then, the sixth linear module 641 drives the second lifting plate 642 to move.

[0057] In practical use, a flipping component 67 is required to drive the assembly to flip 180 degrees. The flipping component 67 includes: a flipping plate 671 and a flipping motor 672 that drives the flipping plate 671 to rotate. The flipping motor 672 is connected to the flipping plate 671, so that the flipping motor 672 drives the flipping plate 671 to rotate.

[0058] In some cases, the flipping motor 672 is connected to the flipping plate 671 via a connecting assembly, the flipping plate 671 being rotatably mounted on the bracket, and the connecting assembly can be a belt and a pulley.

[0059] The assembly / disassembly turntable 1 is also provided with a cleaning component 68 on its periphery. The cleaning component 68 includes a box body 681, an air jet pipe 682 installed inside the box body 681, and a lifting cylinder 683 connected to the box body 681 to drive its lifting and lowering. Multiple cleaning components 68 can be set. After the product is polished by the tumbling mill, component one, component two, and assembly / disassembly fixture 2 may need to be dusted. Therefore, the cleaning components 68 can be set in multiple places as needed. When cleaning is required, the lifting cylinder 683 drives the box body 681 to move downward, so that the box body 681 covers component one, component two, or assembly / disassembly fixture 2 inside the box body 681. Then, the air jet pipe 682 sprays air.

[0060] It should be noted that the jet pipe 682 is connected to an air source, which can be an air storage tank for spraying compressed gas. A water collection box can be installed below the box body 681 as needed.
