[0026] See also Figure 1-8 , an automatic loading and unloading device for a machining center, comprising a machining center 1 and a cabinet 2 located on one side of the machining center 1, wherein a tooling plate supporting mechanism 3, a feeding and retrieving mechanism 4 and a turning mechanism 5 are sequentially installed inside the cabinet 2 from one side to the other side, a movable tooling plate 6 is provided on the tooling plate supporting mechanism 3 for loading workpieces, a cleaning and drying mechanism (not shown in the figure) is installed below the turning mechanism 5 inside the cabinet 2, and the feeding and retrieving mechanism 4 can rotate and retract, on the one hand, the tooling plate 6 is transferred to the machining center 1 by the tooling plate supporting mechanism 3, on the other hand, the tooling plate 6 is taken out of the machining center 1 and transferred to the turning mechanism 5, and on the other hand, the tooling plate 6 is transferred to the tooling plate supporting mechanism 3 by the turning mechanism 5, and after the turning mechanism 5 turns the tooling plate 6 180°, the cleaning and drying mechanism cleans and dries the workpiece on the tooling plate 6.

[0027] In the present invention, a control unit (not shown) is installed inside the cabinet 2, and a human-machine interaction interface 7 electrically connected to the control unit is installed on the panel of the cabinet 2 to perform information exchange with the control unit.

[0028] In the present invention, the tooling plate supporting mechanism 3 includes two support frames 31, and the two support frames 31 are respectively fixedly installed on the inner walls on both sides of one end of the cabinet 2 and are arranged opposite to each other. A first roller group 32 is installed on each support frame 31 along the length direction, and the tooling plate 6 is supported on the first roller groups 32 on both sides, and the front end of the tooling plate 6 is fixedly connected with a female buckle 8.

[0029] Therefore, by providing two support frames 31 and the first roller group 32 , it is possible to support the tooling plate 6 and to move, ie, transfer, the tooling plate 6 .

[0030] In the present invention, a first pneumatic clamp 9 electrically connected to the control unit is installed on the outer side of each support frame 31, which is controlled by the control unit to lock the tooling plate 6 between the two support frames 31 on both sides. A proximity switch (not shown in the figure) electrically connected to the control unit is installed on the inner wall of the cabinet 2 on one side facing the rear side of the tooling plate 6 to detect the arrival signal of the tooling plate 6 and transmit it to the control unit.

[0031] In the present invention, a platform 10 is fixedly connected to the middle part of the cabinet 2, and the feeding and picking mechanism 4 includes a rotating table 41, a track 42, a walking platform 43, a supporting platform 44 and a push-pull member 45. The rotating table 41 is rotatably installed on the platform 10, the track 42 is fixed on the rotating table 41, the walking platform 43 is installed on the track 42 and can move along the track 42, the supporting platform 44 is fixed on the walking platform 43, and second roller groups 46 are respectively installed on both sides of the supporting platform 44 along the length direction to realize the transfer of the tooling plate 6. The pushing and pulling member 45 can move laterally along the length direction of the supporting platform 44, and the front side of the pushing and pulling member 45 is fixedly connected with a male buckle 11 that matches the female buckle 8.

[0032] In the present invention, a first drive motor 12 electrically connected to the control unit is installed at the bottom of the platform 10. Under the control of the control unit, the output shaft of the first drive motor 12 passes through the platform 10 upward and is installed with a driving gear 13. The bottom surface of the rotating table 41 is installed with a driven gear 14 meshing with the driving gear 13.

[0033] Therefore, the control unit controls the first drive motor 12 to drive the rotating table 41 to rotate on the platform 10 (including forward and reverse rotation), thereby driving the support table 44 and the push-pull member 45 to rotate. In addition, the walking table 43 walks along the track 42, that is, it is extended and retracted, and the push-pull member 45 is used to move horizontally along the length direction of the support table 44, so as to realize the transfer of the tooling plate 6 between the machining center 1, the tooling plate supporting mechanism 3 and the flipping mechanism 5, thereby realizing the loading and unloading of the workpiece.

[0034] In the present invention, a screw rod 15 extending along its length direction is rotatably installed on one side of the support platform 44, and a second drive motor (not shown in the figure) for driving the screw rod 15 to rotate forward and reverse is installed. The second drive motor is electrically connected to the control unit and is controlled by the control unit. A guide rod 16 extending along its length direction is fixedly installed on the other side of the support platform 44. After the push-pull member 45 spans the width direction of the support platform 44, it is installed on the screw rod 15 by threaded fit on the one hand, and installed on the guide rod 16 by sliding fit on the other hand.

[0035] Therefore, the control unit controls the second drive motor to drive the screw rod 15 to rotate forward and reverse, so that the push-pull member 45 moves laterally (including forward and backward) along the screw rod 15 and the guide rod 16, and moves laterally along the length direction of the support platform 44, thereby pushing and pulling the tooling plate 6.

[0036] In the present invention, the flipping mechanism 5 includes two flipping support frames 51, which are respectively and correspondingly mounted on the inner walls on both sides of the other end of the cabinet 2 and are arranged opposite to each other. An upper roller group and a lower roller group 52 are installed on each flipping support frame 51 along the length direction for clamping the tooling plate 6. A stop block 53 is fixedly connected to the end of each flipping support frame 51 for limiting the tooling plate 6. A water pool 17 is installed inside the cabinet 2 below the two flipping support frames. The cleaning and drying mechanism includes a first nozzle group (not shown in the figure) for spraying water upward and a second nozzle group (not shown in the figure) for spraying air upward. The first nozzle group and the second nozzle group are both installed in the water pool 17, and solenoid valves (not shown in the figure) electrically connected to the control unit are installed in the pipelines of the first nozzle group and the second nozzle group, so that the first nozzle group and the second nozzle group are both controlled by the control unit.

[0037] In the present invention, a second pneumatic clamp (not shown in the figure) electrically connected to the control unit is installed on the outer side of each flip support frame 51, which is controlled by the control unit and is used to lock the tooling plate 6 between the two flip support frames 51 on both sides; a dual-axis motor 18 electrically connected to the control unit is installed at the bottom of the cabinet 2, and the two output shafts of the dual-axis motor 18 are respectively connected to the two flip support frames 51 for transmission.

[0038] Therefore, the control unit controls the dual-axis motor 18 to drive the two flip support frames 51 to rotate forward and reverse, so as to flip the tooling plate 6 upward and downward by 180°, so that it faces upward and downward.

[0039] In the present invention, the shell of the machining center 1 is provided with a feed port and a lifting door 19 on the side facing the feeding and picking mechanism 4. The lifting door 19 is driven to rise and fall by a cylinder 20. The cylinder 20 is electrically connected to the control unit and is opened and closed by the control unit.

[0040] The present invention will be further described below with reference to the accompanying drawings: The tooling plates 6 used in the present invention include two pieces, namely, tooling plate A and tooling plate B, both of which are provided with a clamping groove for clamping a workpiece and matching with the workpiece.

[0041] In the initial state, the tooling plate A is located between the two support frames 31 and supported by the first roller group 32, and the tooling plate B is located between the two flip support frames 51 and limited and supported by the upper roller group and the lower roller group 52, and is set upward. At this time, the first pneumatic clamp 9 and the second pneumatic clamp lock the tooling plate A and the tooling plate B respectively.

[0042] When in use, the operator inserts the workpiece to be processed into the slot on the tooling plate A, and then the operator starts the entire loading and unloading device by pressing the control button on the human-machine interaction interface 7.

[0043] Next, the first drive motor 12 drives the rotating table 41 to rotate, so that the support platform 44 and the push-pull member 45 face the tooling plate supporting mechanism 3, and the second drive motor drives the screw rod 15 to rotate forward, and the push-pull member 45 moves forward until the male buckle 11 is inserted into the female buckle 8.

[0044] Then, the first pneumatic clamp 9 is unlocked, the second drive motor drives the screw rod 15 to reverse, the push-pull member 45 retreats, and the tooling plate A is pulled onto the support platform 44 .

[0045] Then, the first drive motor 12 drives the rotating table 41 to rotate 90° clockwise, so that the support platform 44 and the push-pull member 45 face the lifting door 19, and the control unit then drives the lifting door 19 to lift by controlling the oil cylinder 20 to open the feed port.

[0046] Then, the walking platform 43 moves forward and extends along the track 42, and then, the second drive motor drives the screw 15 to rotate forward, and the push-pull member 45 moves forward until the tooling plate A is pushed to the workbench of the machining center 1, and the locking tool thereon locks the tooling plate A immediately.

[0047] Then, the walking platform 43 and the push-pull member 45 retreat successively, and the male buckle 11 is separated from the female buckle 8 .

[0048] After exiting the feed port, the control unit drives the lifting door 19 to descend by controlling the oil cylinder 20 to close the feed port, and then the machining center 1 can be started to perform corresponding mechanical processing on the workpiece on the tooling plate A.

[0049] Then, the first drive motor 12 drives the rotating table 41 to rotate clockwise 90° again, so that the support platform 44 and the push-pull member 45 face the flip mechanism 5, and the second drive motor drives the screw rod 15 to rotate forward, and the push-pull member 45 moves forward until the male buckle 11 is inserted into the female buckle 8.

[0050] Then, the second pneumatic clamp is unlocked, the second drive motor drives the screw rod 15 to reverse, the push-pull member 45 retreats, and the tooling plate A is pulled onto the support platform 44 .

[0051] Then, the first drive motor 12 drives the rotating table 41 to rotate 180° counterclockwise, so that the support platform 44 and the push-pull member 45 face the tooling plate supporting mechanism 3. Then, the second drive motor drives the screw 15 to rotate forward, and the push-pull member 45 moves forward until the tooling plate B is pushed between the two support frames 31. When the proximity switch detects that the tooling plate B is in place, the control unit immediately controls the first pneumatic clamp 9 to lock the tooling plate B.

[0052] At this time, the operator can clamp the next batch of workpieces to be processed into the slots on the tooling plate B and wait for processing.

[0053] When the machining center 1 completes the machining of the workpiece on the tooling plate A, the lifting door 19 is lifted, the feed port is opened, and the feeding mechanism 4 pulls the tooling plate A from the machining center 1 according to the above process and pushes it between the two flip support frames 51, and the second pneumatic clamp thereon immediately locks the tooling plate A.

[0054] Then, the first driving motor 12 drives the rotating table 41 to rotate 180° counterclockwise again, so that the supporting platform 44 and the push-pull member 45 face the tooling plate supporting mechanism 3, and according to the above process, the tooling plate B is pushed to the workbench of the machining center 1 to perform corresponding mechanical processing.

[0055] In addition, the control unit controls the dual-axis motor 18 to drive the two flip support frames 51 to reverse, flipping the tooling plate A downward 180° to face downward. Then, the control unit controls the first nozzle group and the second nozzle group to work successively to clean and dry the processed workpiece.

[0056] After cleaning and drying, the feeding and taking mechanism 4 pulls the tooling plate A through the flipping mechanism 5 according to the above process and pushes it between the two support frames 31 , and the first pneumatic clamp 9 thereon locks the tooling plate A immediately.

[0057] After the operator takes out the processed workpiece, the subsequent batch of workpieces to be processed are clamped into the clamping slot on the tooling plate A and wait for processing.

[0058] The above process is repeated in a cycle to sequentially carry out the loading, processing, cleaning, drying and unloading of the workpiece.

[0059] It should be noted that the automatic loading and unloading device of the present invention can be adapted to the processing of new energy vehicle parts, medical equipment parts, and parts for ships, aerospace, and military enterprises, etc. It can achieve energy saving and consumption reduction, improve production efficiency, reduce the workload of operators, and provide reliable safety protection.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0061] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
