Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0067] The utility model aims to provide an automatic turning over feeding and stacking system, which is used for processing and manufacturing a flat plate, and the flat plate is a filter plate.

[0068] like Figures 1 to 3As shown, the automatic flipping loading and stacking system involved in the utility model includes a processing machine tool 10, a main frame 20 and a clamping mechanism 30. A loading station and a unloading stacking station are provided in the main frame 20. The loading station is used to stack unprocessed flat plates 80, and the unloading stacking station is used to stack processed flat plates 90; the clamping mechanism 30 includes a clamping frame 31, a clamping area 32 arranged in the clamping frame 31 and capable of accommodating a flat plate, and a clamping drive source 33 installed on the clamping frame 31; the clamping frame 31 is movably and rotatably installed on the main frame 20, so that the clamping mechanism 30 is movably and rotatably installed on the main frame 20 as a whole; the output end of the clamping drive source 33 is located in the clamping area 32, and can move in the direction of approaching or moving away from the flat plate in the clamping area 32, so as to clamp or release the flat plate in the clamping area 32. The movement of the clamping frame 31 can realize reciprocating movement between the processing machine 10, the loading station and the unloading stacking station, and the rotation of the clamping frame 31 can realize 180° flipping of the clamped flat plate.

[0069] When the above-mentioned automatic flipping loading and stacking system is used for the processing of the flat plate, the clamping frame 31 moves to the loading station and clamps the unprocessed flat plate 80 at the loading station; thereafter, the clamping frame 31 moves to the processing machine 10 with the unprocessed flat plate 80 clamped therein, and releases the unprocessed flat plate 80 to realize the automatic loading of the flat plate; after the processing machine 10 has processed one side of the unprocessed flat plate 80, the clamping frame 31 clamps the unprocessed flat plate 80 on the processing machine 10 again and rotates 180°, thereby flipping the unprocessed flat plate 80 180°, so that the processing machine 10 can process the other side of the unprocessed flat plate 80; after the double-sided processing of the flat plate is completed, the flat plate is the processed flat plate 90, and the clamping frame 31 clamps the processed flat plate 90 and moves to the unloading and stacking station with the processed flat plate 90 to realize the automatic unloading and stacking of the flat plate. Therefore, the present application realizes that the clamping frame 31 drives the clamped flat plate to move between the processing machine 10, the loading station and the unloading and stacking station, and flips the clamped flat plate 180° through the movement and rotation of the clamping frame 31, as well as the clamping and releasing of the flat plate by the clamping frame 31, thereby automatically realizing the loading, flipping and unloading and stacking of the flat plate, and the whole process is safe and efficient.

[0070] Furthermore, if Figure 1 As shown, the automatic flip loading and stacking system also includes a loading tray 60 and a unloading tray 70. The loading tray 60 is arranged at the loading station, and the unloading tray 70 is arranged at the unloading and stacking station. Both the loading tray 60 and the unloading tray 70 are used to stack flat panels. Both the loading tray 60 and the unloading tray 70 can be picked up by a forklift, so that the forklift can conveniently transfer a pile of unprocessed flat panels 80 that have been stacked to the loading station, and transfer a pile of processed flat panels 90 that have been stacked at the unloading and stacking station away, thus realizing the automatic transfer of flat panels.

[0071] Furthermore, if Figures 1 to 3 As shown, the automatic flip loading and stacking system also includes a moving mechanism 40, a lifting mechanism 50 and a main control cabinet 110. The moving mechanism 40 is movably mounted on the main frame 20 in the horizontal direction, the lifting mechanism 50 is movably mounted on the moving mechanism 40 in the vertical direction, and the clamping frame 31 is rotatably mounted on the lifting mechanism 50 around a horizontal axis; the moving direction of the moving mechanism 40 is consistent with the parallel direction of the processing machine 10, the loading station and the unloading and stacking station. Therefore, the clamping frame 31 is driven to move horizontally by the moving mechanism 40, and is driven to move up and down by the lifting mechanism 50, so as to realize the movement of the clamping frame 31 between the processing machine 10, the loading station and the unloading and stacking station.

[0072] For the convenience of description, in the following embodiments, the moving direction of the moving mechanism 40 on the main frame 20 is defined as the front-to-back direction. Figure 1 and Figure 3 In the view shown, the left side of the paper is the rear direction, and the right side of the paper is the front direction. Figure 1 and Figure 3 As shown, the material unloading and stacking station, the material loading station and the processing machine 10 are preferably arranged from back to front, and the material unloading and stacking station and the material loading station are both distributed in the main frame 20. The processing machine 10 is a CNC machine tool, and the part of the processing machine 10 for placing the workpiece is also distributed in the main frame 20, so as to facilitate the loading and unloading of the plate. The following describes the preferred structure of the main frame 20, the moving mechanism 40, the lifting mechanism 50 and the clamping mechanism 30 in the automatic flip loading and stacking system.

[0073] Main frame 20

[0074] like Figures 4 to 6 As shown, the main frame 20 includes a fixed frame body 21, a pair of frame main beams 22 fixed to the upper end of the frame body 21, and a transmission rack 23 fixed to one of the frame main beams 22. The two frame main beams 22 are arranged side by side, and the frame main beams 22 and the transmission rack 23 extend straightly forward and backward along the moving direction of the moving mechanism 40. The frame body 21 includes four fixed columns 211 distributed at four corners, and two frame cross beams 212 extending left and right and arranged side by side front and back. The lower ends of the fixed columns 211 are fixed to the workshop floor by anchor bolts, the rear frame cross beam 212 is fixed to the upper ends of the two rear fixed columns 211, the front frame cross beam 212 is fixed to the upper ends of the two front fixed columns 211, and the frame main beam 22 is fixed across the top of the two frame cross beams 212.

[0075] Preferably, the main frame 20 may also be provided with some intermediate support rods or diagonal support rods between two adjacent fixed columns 211, between the fixed columns 211 and the frame cross beam 212, and between the fixed columns 211 and the frame main beam 22 to improve the structural strength of the main frame 20. However, the provision of the intermediate support rods or diagonal support rods shall not affect the movement of the moving mechanism 40, the lifting mechanism 50 and the clamping mechanism 30, nor shall it affect the entry and exit of the workpiece to be processed. In addition, a safety light curtain is preferably installed on the side of the main frame 20 to ensure the safety of personnel and equipment.

[0076] Furthermore, if Figure 4 and Figure 6 As shown, the main frame 20 also includes a first linear guide 24 and a first stopper 25 fixed on each frame main beam 22. The first linear guide 24 is parallel to the transmission rack 23 and extends straightly forward and backward. The first stopper 25 abuts against the front and rear ends of the first linear guide 24. The first linear guide 24 is used to provide guidance for the forward and backward movement of the following moving mechanism 40, and the first stopper 25 is used to limit the forward and backward movement range of the following moving mechanism 40. In addition, a detection switch can be installed at each position of the frame main beam 22, and the detection switch is connected to the main control cabinet 110 for controlling the start and stop positions of the following moving mechanism 40 as needed.

[0077] Mobile mechanism 40

[0078] like Figures 7 to 9 As shown, the mobile mechanism 40 includes a bottom frame 41 spanning between a pair of frame main beams 22, a mobile drive source 42 fixed on the bottom frame 41, and a rotatable transmission gear 43. The mobile drive source 42 is connected to the transmission gear 43; the transmission gear 43 is meshed with the transmission rack 23. The mobile drive source 42 is preferably a servo motor and is communicatively connected to the main control cabinet 110. The transmission gear 43 is directly fixed on the motor shaft of the mobile drive source 42. When the main control cabinet 110 sends an instruction to the mobile drive source 42, the mobile drive source 42 is actuated to drive the transmission gear 43. The transmission gear 43 is driven to move forward and backward along the transmission rack 23 through the meshing of the transmission gear 43 and the transmission rack 23, thereby driving the bottom frame 41 to move forward or backward, thereby realizing that the mobile mechanism 40 drives the lifting mechanism 50 and the clamping mechanism 30 to move forward or backward. Preferably, as Fig. 9 As shown, the bottom frame 41 is a Japanese-shaped frame, and the mobile driving source 42 is installed at the left front end of the Japanese-shaped frame. The mobile mechanism 40 also includes a reinforcing triangular rib 411, which is welded between the supporting column 45 and the Japanese-shaped frame.

[0079] like Figure 7 and Figure 8As shown, a first slider 44 is provided on the lower end surface of the bottom frame 41, and the first slider 44 is slidably matched with the first linear guide rail 24 in the main frame 20, so as to improve the stability of the bottom frame 41 when moving forward or backward. At the same time, a first detector is also provided on the lower end surface of the bottom frame 41, and the first detector is connected to the main control cabinet 110 for communication, and the first detector can sense the first limit block 25. Specifically, when the bottom frame 41 moves forward to the front end of the first linear guide rail 24, the first detector can sense the first limit block 25 at the front end of the first linear guide rail 24; when the bottom frame 41 moves backward to the rear end of the first linear guide rail 24, the first detector can sense the first limit block 25 at the rear end of the first linear guide rail 24. Therefore, the main control cabinet 110 can control the limit position of the bottom frame 41 when it moves forward and backward according to the feedback signal of the first detector, and effectively limit the bottom frame 41 to move forward and backward within the length range of the first linear guide rail 24.

[0080] Furthermore, if Figures 7 to 9 As shown, the mobile mechanism 40 also includes a pair of support columns 45 whose lower ends are fixed on the bottom frame 41, a support beam 46 fixed on the upper ends of the pair of support columns 45, a lifting drive source 47 fixed at the middle position of the support beam 46, and a transmission screw 48 extending up and down and rotatably supported in the support beam 46 through a bearing. The bottom frame 41 is movably mounted on the top of the main frame 20, and the pair of support columns 45 are arranged side by side front and back, and the support beam 46 extends straight front and back. Preferably, the lifting drive source 47 is a servo motor and is connected to the main control cabinet 110 for communication, and the upper end of the transmission screw 48 is connected to the motor shaft of the lifting drive source 47 through a coupling. The lifting drive source 47 and the transmission screw 48 are used to drive the lifting mechanism 50 described below to move up and down.

[0081] Preferably, if Figures 4 to 9 As shown, the moving mechanism 40 also includes a second linear guide 49 and a second stopper 410 fixed to the inner side of each supporting column 45. The second linear guide 49 is parallel to the transmission screw 48 and extends up and down. The second stopper 410 abuts against the upper and lower ends of the second linear guide 49. The second linear guide 49 is used to provide a guide for the up and down movement of the lifting mechanism 50 described below, and the second stopper 410 is used to limit the range of the up and down movement of the lifting mechanism 50 described below. In addition, a detection switch can be installed at each position of the supporting column 45, and the detection switch is connected to the main control cabinet 110 for controlling the start and stop positions of the lifting frame 51 described below as needed.

[0082] Lifting mechanism 50

[0083] like Figures 10 to 12As shown, the lifting mechanism 50 includes a lifting frame 51, and a transmission nut 52 fixed in the lifting frame 51, and the transmission nut 52 is threadedly matched with the transmission screw 48. When the main control cabinet 110 sends an instruction to the lifting drive source 47, the lifting drive source 47 is actuated to drive the transmission screw 48 to transmit, and the transmission nut 52 is driven to move up and down along the transmission screw 48 through the threaded match between the transmission nut 52 and the transmission screw 48, thereby driving the lifting frame 51 to move up or down, and thus realizing that the lifting mechanism 50 drives the clamping mechanism 30 to move up or down.

[0084] Furthermore, if Figures 10 to 12 As shown, the lifting frame 51 includes a pair of door-type frames 511, a lifting beam 512 fixed on the top of the pair of door-type frames 511, and a second slider 53 fixed on the top of the outer side of each door-type frame 511; the door-type frame 511 is also called a gantry frame, and the pair of door-type frames 511 are arranged side by side, and the lifting beam 512 extends straightly front and back; the pair of door-type frames 511 are distributed on the inner side of a pair of supporting columns 45, and the door-type frames 511 constitute the cantilever of the door-type frames 511, and the transmission nut 52 is fixed at the middle position of the lifting beam 512, and the second slider 53 is slidably matched with the second linear guide rail 49 to improve the stability of the lifting frame 51 moving up or down. At the same time, a second detector is also installed on the door-type frame 511, and the second detector is connected to the main control cabinet 110 for communication, and the second detector can sense the second limit block 410. Specifically, when the lifting frame 51 moves up to the upper end of the second linear guide 49, the second detector can sense the second limit block 410 at the upper end of the second linear guide 49; when the lifting frame 51 moves down to the lower end of the second linear guide 49, the second detector can sense the second limit block 410 at the lower end of the second linear guide 49. Therefore, the main control cabinet 110 can control the limit position of the lifting frame 51 when it moves up and down according to the feedback signal of the second detector, and effectively limit the lifting frame 51 to move up and down within the length range of the second linear guide 49.

[0085] Furthermore, if Figures 10 to 12 As shown, the lifting mechanism 50 also includes a flip driving source 54, a first coupling 55 and a second coupling 56. The flip driving source 54 is preferably a servo motor and is connected to the main control cabinet 110. The flip driving source 54 is fixed to the lower end of the rear door-type frame 511. The first coupling 55 is rotatably supported at the lower end of the rear door-type frame 511 through a bearing. The motor shaft of the flip driving source 54 is connected to the first coupling 55. The second coupling 56 is rotatably supported at the lower end of the front door-type frame 511 through a bearing. The first coupling 55 is coaxial with the second coupling 56. The flip driving source 54, the first coupling 55 and the second coupling 56 are used to drive the following clamping mechanism 30 to rotate around a horizontal axis extending forward and backward.

[0086] Clamping mechanism 30

[0087] like Figures 13 to 15 As shown, the clamping frame 31 is a square-shaped frame, and the clamping mechanism 30 also includes a driving shaft 34 and a driven shaft 35 that extend forward and backward and are coaxial. The driving shaft 34 is fixed at the middle position of the rear side of the clamping frame 31 and is connected to the first coupling 55. The driven shaft 35 is fixed at the middle position of the front side of the clamping frame 31 and is connected to the second coupling 56. In this way, when the main control cabinet 110 controls the flip driving source 54 to operate, the flip driving source 54 drives the first coupling 55 to rotate, thereby driving the driving shaft 34 and the driven shaft 35 to rotate, and also driving the clamping frame 31 and the plate therein to rotate, so as to achieve a 180° flip of the plate.

[0088] Furthermore, if Figures 13 to 15 As shown, there are four clamping drive sources 33, all of which are cylinders. The four cylinders are respectively mounted on the front and rear sides of the square frame, and the cylinder piston rod of each cylinder can be telescopically placed in the clamping area 32, thereby clamping the plate in the clamping area 32 or releasing the plate in the clamping area 32. In other embodiments, the clamping drive sources 33 can also be set in other quantities, and the specific quantity depends on the size and weight of the plate.

[0089] Preferably, a detection component is installed on the door-shaped frame 511, and the detection component is communicatively connected with the main control cabinet 110 to ensure that the clamping frame 31 and the processed workpiece rotate within the allowable height and angle range.

[0090] In summary, the working principle of the automatic flipping, loading and stacking system with the above structure is as follows.

[0091] 1. Loading of workpieces: The worker uses a forklift to transport the loading tray 60 and the unprocessed plate 80 thereon to the loading station, and the forklift and the worker exit the working range.

[0092] 2.
