[0077] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0078] like Figure 1-Figure 3 A double-station matching machine with automatic feeding function is shown, comprising:

[0079] Rack 1;

[0080] A feeding mechanism 4 is arranged on the frame 1, and the feeding mechanism 4 includes a material rack 44, and the material rack 44 is used to place workpieces;

[0081] A turntable mechanism 2 is arranged on the frame 1, and a plurality of mold assemblies 3 are arranged on the turntable mechanism 2, and the turntable mechanism 2 can drive the mold assemblies 3 to rotate;

[0082] The actuator 5 is arranged above the actuator position of the turntable mechanism 2 .

[0083] In this embodiment, the workpiece includes a cup bottom and a cup body, and the material rack 44 is used to place the cup bottom.

[0084] When the mold assembly 3 on the turntable mechanism 2 is located at the first loading position, the loading mechanism 4 grabs the cup bottom located on the material rack 44 and delivers it to the mold assembly 3;

[0085] Then the turntable mechanism 2 drives the mold assembly 3 to move to the second loading position, and the cup body is also placed in the mold assembly 3;

[0086] When the turntable mechanism 2 drives the mold assembly 3 to pass the first loading position and the second loading position, the cup bottom and the cup body are already placed in the mold assembly 3. At this time, the turntable mechanism 2 drives the mold assembly 3 to move to the execution position, and then the actuator 5 completes the connection of the workpiece.

[0087] The connected workpieces will be brought to the discharge position by the turntable mechanism 2 and separated from the mold assembly 3.

[0088] Furthermore, the turntable mechanism 2 includes:

[0089] Rotating disk 21;

[0090] An indexer 22 connected to the carrier plate 23, and the indexer 22 can drive the carrier plate 23 to rotate;

[0091] The indexer 22 is connected to the driving motor 29 and driven by the driving motor 29 .

[0092] The rotating disk 21 is fixed on the supporting disk 23. When the driving motor 29 is working, the supporting disk 23 can drive the rotating disk 21 to rotate synchronously, thereby driving the mold assembly 3 to pass through the first loading position, the second loading position, the execution position and the discharge position in sequence.

[0093] like Figure 1-Figure 5 As shown, a material return mechanism 6 is provided in the frame 1, and the material return mechanism 6 includes:

[0094] A material ejector 63, which is used to push the workpiece that has been connected in the mold assembly 3 out of the mold assembly 3;

[0095] The second driving component 61 is used to drive the material ejection push rod 63 to move;

[0096] A material-removing pad 64 is provided at the end of the material-removing push rod 63. The material-removing pad 64 is used to reduce the pressure directly applied to the formed workpiece, thereby preventing the workpiece from being deformed during the material-removing process, thereby affecting the product quality and appearance.

[0097] A through hole is opened in the mold assembly 3, so that the material-removing push rod 63 can enter the mold groove 36 of the mold assembly 3 through the through hole, thereby pushing the completed connected workpiece out of the mold groove 36 to complete the material-removing work.

[0098] like Figure 1-Figure 5 As shown, the second driving component 61 is penetrated on the fixing frame 8, and a second positioning hole 13 is opened on the working table 11 of the frame 1, and the second positioning hole 13 is located below the material withdrawal position. The second positioning hole 13 is located below the material withdrawal position.

[0099] The fixing frame 8 includes a supporting plate 81 and a fixing rod 82 . The second driving component 61 is arranged on the supporting plate 81 . The supporting plate 81 is connected to the frame 1 through the fixing rod 82 .

[0100] A stabilizing rod member 15 is provided at the positioning hole 13, and a stabilizing rod hole 16 is formed in the stabilizing rod member 15. The connecting rod 62 of the driving component 61 is inserted into the stabilizing rod hole 16. The stabilizing rod member 15 is used to limit the position of the connecting rod 62 and reduce the shaking of the connecting rod 62 to ensure that the connecting rod 62 can stably drive the ejection push rod 63 to enter the mold groove 36.

[0101] like Figure 1-Figure 8 As shown, a positioning frame 7 is provided on the frame 1 , and the actuator 5 is fixed on the positioning frame 7 .

[0102] A boss portion 24 is protrudingly formed on the inner side of the carrier plate 23 . A fixing hole 25 is formed in the boss portion 24 . A bearing 26 is disposed in the fixing hole 25 .

[0103] A center hole 28 is formed on the rotating disk 21 , and the center of the center hole 28 is coaxial with the center of the rotating disk 21 ; the inner diameter of the center hole 28 matches the outer diameter of the boss portion 24 , so that the rotating disk 21 can be sleeved on the outside of the boss portion 24 through the center hole 28 .

[0104] The positioning frame 7 includes a loading platform 73, the actuator 5 is arranged on the loading platform 73, a support rod 71 and a positioning rod 72 are formed on the loading platform 73, and the end of the positioning rod 72 is inserted into the bearing 26. A positioning hole 12 is opened on the working table 11 of the frame 1. After the positioning rod 72 passes through the indexer 22, the end of the positioning rod 72 will be fixed in the positioning hole 12.

[0105] When the positioning rod 72 is inserted into the fixing hole 25, the positioning rod 72 is coaxial with the carrier plate 23. The center hole 28 is also coaxial with the carrier plate 23 through the cooperation with the boss portion 24, so that the axis of the positioning rod 72 is coaxial with the center of the rotating plate 21.

[0106] Since the rotating disk 21 is in original shape, the distance from the mounting hole 27 for placing the mold assembly 3 to the center of the rotating disk 21 is fixed.

[0107] Therefore, when the distance between the actuator 5 and the center of the positioning rod 72 on the positioning frame 7 is equal to the distance between the mounting hole 27 and the center of the rotating disk, it can be ensured that the moving path of the mold assembly 3 can stably pass under the actuator 5, thereby determining the position between the actuator 5 and the mold assembly 3 and achieving accurate installation position.

[0108] The lower end of the support rod 71 abuts against the frame 1 , thereby supporting the positioning frame 7 .

[0109] Furthermore, the loading platform 73 is triangular, the positioning rod 72 is arranged at one corner, and the support rod 71 is arranged at the other two corners. Because the distance between the positioning rod 72 and the support rod 71 is greater than the radius of the rotating disk 21, when the lower end of the support rod 71 abuts against the frame 1, the rotation of the rotating disk 21 will not be hindered.

[0110] like Figure 1-Figure 11 As shown, the mold assembly 3 includes:

[0111] A fixing seat 31 is inserted into the mounting hole 27 of the rotating disk 21, and the upper edge of the fixing seat 31 abuts against the upper surface of the rotating disk 21 to prevent the fixing seat 31 from passing through the mounting hole 27 from above;

[0112] A movable rod 32 is inserted into the fixed seat 31, and a spring 37 is sleeved on the outer side of the movable rod 32;

[0113] The base 33 is arranged at the upper end of the movable rod 32, and the two ends of the spring 37 are respectively against the base 33 and the fixed base 31, so that the base 33 is lifted to a certain height;

[0114] A first mold 34, which is disposed at the upper end of the base 33;

[0115] A second mold 35, which is sleeved on the upper end of the first mold 34;

[0116] After the first mold 34 and the second mold 35 are connected into one body, a mold groove 36 is formed inside the first mold 34 and the second mold 35 , and the mold groove 36 is used to load the workpiece.

[0117] A fixing ring 38 is also provided on the fixing seat 31, and the fixing ring 38 is used to fix the movable rod 32 to prevent the movable rod 32 from tilting. A retaining ring 39 is sleeved on the lower end of the movable rod 32 to prevent the movable rod 32 from escaping from the fixing seat 31 from above.

[0118] A through hole 1 320 is formed inside the movable rod 32, a through hole 2 330 is formed inside the base 33, and a through hole 340 is formed inside the first mold 34. The through hole 1 320, the through hole 2 330 and the through hole 340 are located on the same straight line and allow the ejector rod 63 to pass through.

[0119] The second mold 35 can be sleeved on the upper end of the first mold 34, and the corresponding mold can be replaced according to the actual size of the cup to be produced, so as to match the design requirements and provide a better effect of fixing the workpiece.

[0120] like Figure 1-Figure 11 As shown, the actuator 5 includes a pressure plate 53 and a driving component 15. The driving component 15 is connected to the pressure plate 53 through a connecting rod 152 and can drive the pressure plate 53 to move along the vertical direction.

[0121] A support seat 14 is provided on the working table 11 of the frame 1, and the support seat 14 is located below the execution position;

[0122] When the mold assembly 3 is located at the execution position, the driving component 1 51 drives the pressure plate 53 to move toward the mold assembly 3, and presses the workpiece and the cup body in the mold assembly 3 into shape.

[0123] The abutment seat 14 is used to limit the movable rod 32 of the mold assembly 3 from continuing to move downward, thereby fixing the position of the column base 33 to improve the effect of the press molding.

[0124] like Figure 1-Figure 12 As shown, the feeding mechanism 4 also includes:

[0125] A material grabbing assembly, which is used to pick up workpieces from a material rack 44;

[0127] The rotating material tray 43 has a plurality of material racks 44 disposed thereon, and the rotating material tray 43 can drive the material racks 44 to rotate.

[0128] The shifting assembly 41 is used to drive the grabbing assembly to move above the first loading position and place the workpiece into the mold assembly 3 .

[0129] As a preferred technical solution, the material grabbing component can be a suction cup. When the robot arm 45 drives the mobile frame 42 to move above the material frame 44, it will drive the mobile frame 42 and the suction cup thereon to descend, so as to grab the workpiece on the material frame 44.

[0130] Specific as Figure 1 and Fig.12 As shown, the movable frame 42 is in a “Y” shape, and is formed with a connecting portion 46 and two mounting portions 47 . The two mounting portions 47 are both formed on one end of the connecting portion 46 . The connecting portion 46 is used to connect to the robot arm 45 .

[0131] The mounting portion 47 is used to set the material grabbing assembly, so that the moving frame 42 can drive the two material grabbing assemblies to move at the same time and can perform the material grabbing action at the same time.

[0132] At least eight mounting holes 27 are formed on the rotating disk 21 , so that after each rotation, at least two mold assemblies 3 are located in the first loading position, the second loading position, the execution position and the discharge position.

[0133] As a preferred technical solution, the feeding mechanism 4 includes two rotating feeding trays 43, so that the grabbing assembly can simultaneously feed the mold assembly 3 located in the first feeding position to improve production efficiency.

[0134] Specific as Figure 2 As shown, a protective shell 17 is also provided on the frame 1, and a loading door 18 is provided on the protective shell 17. The loading door 18 faces the rotating material tray 43. After the loading door 18 is opened, the workpiece can be directly placed on the material rack 44 of the rotating material tray 43.

[0135] An opening 19 is formed at one end of the protective shell 17, and the opening 19 faces the second feeding position and the unloading position, so that the workpiece can be fed into the mold assembly 3 in the second loading position through the opening 19, and the connected workpiece can also leave through the opening 19. This process can be performed manually or in conjunction with other transportation equipment to achieve fully automated production.
