DETAILED DESCRIPTION

[0021] The hot pressing forming feeding device 3, referring to Figure 1 , Figure 2 and Figure 3, including a mounting seat 31 and a mobile feeding mechanism, the mobile feeding mechanism is mounted on the mounting seat 31; a feeding cylinder 39 is mounted on the mounting seat 31, a discharge seat 38 is mounted on the feeding cylinder 39, the discharge seat 38 is connected to the cylinder rod of the feeding cylinder 39, the feeding cylinder 39 and the discharge seat 38 are located below the mobile feeding mechanism; a discharge position with openings on both sides is provided on the discharge seat 38, one side opening of the discharge position is connected to the feeding mechanism (such as a vibration plate 21) to realize automatic feeding of the workpiece 10; a transfer cylinder 36 is mounted on the mobile feeding mechanism, the transfer cylinder 36 is connected to an air clamp 361 for clamping the workpiece 10 from the discharge seat 38, and the air clamp 361 is clamped or opened by the transfer cylinder 36.

[0022] A sensor 310 is also installed on the mounting seat 31. The sensor 310 is arranged next to the discharge seat 38 and opposite to the opening on the other side of the discharge position to form a sensing structure for the workpiece 10 to enter into place, that is, the workpiece 10 will be detected by the sensor 310 after it is delivered into place, and then the next operation will be carried out.

[0023] The discharge position is arranged at the front end of the discharge seat 38, and a guide frame 37 is arranged in front of the discharge seat 38 and the feeding cylinder 39. There is a space in the middle of the guide frame 37 for accommodating the discharge seat 38. The discharge seat 38 is pushed forward by the feeding cylinder 39 so that the discharge position enters the space of the guide frame 37, and the workpiece 310 can be clamped by the clamp 361 at this time. At the same time, because the discharge position enters between the guide frames 37, the opening on one side of the discharge position is no longer opposite to the feeding mechanism, and the outlet of the feeding mechanism is blocked by the blocking side wall of the discharge seat 38, and the workpiece 10 will not enter the discharge position at this time. When the discharge seat 38 is reset, the workpiece 10 will enter the discharge position through the opening again, thereby realizing orderly feeding.

[0024] The mobile feeding mechanism includes a Z-axis cylinder 32, an X-axis mechanism 33 and an X-axis cylinder 34. The Z-axis cylinder 32 is mounted on the mounting seat 31. The X-axis mechanism 33 is connected to the Z-axis cylinder 32 to form a structure capable of lifting and lowering.

[0025] The hot pressing forming mechanism, referring to Figure 1 , Figure 4 and Figure 5, including a press 9 (JH31-300 press can be used), a heating and feeding module 1 and a robot 7 (such as ABB six-axis robot IRB 1600) for feeding the workpiece 10 into the press 9, the robot 7 is arranged between the heating and feeding module 1 and the press 9; the heating and feeding module 1 includes a feeding mechanism, a high-frequency heating device 4 and the aforementioned feeding device 3, the feeding mechanism, the high-frequency heating device 4 and the feeding device 3 are installed on a feeding machine base 2, and the feeding device 3 is connected to the feeding mechanism; a supporting mechanism 5 is arranged at the position connected to the feeding device 3, and the heating coil 41 of the high-frequency heating device 4 is connected to the supporting mechanism 5, which is used to heat the workpiece 10 placed on the supporting mechanism 5.

[0026] The feeding mechanism adopts a vibrating plate 21, and the discharge track of the vibrating plate 21 is horizontally connected to the discharge seat 38 (discharge position) of the feeding device 3. After the vibrating plate 21 vibrates the workpiece 10 to a horizontal placement state, it enters the discharge position through an opening on the side of the discharge position.

[0027] The support mechanism 5 includes a support seat 51 and a lifting cylinder 52. The lifting cylinder 52 is installed on the mounting seat 31 of the feeding device 3. The support seat 51 is installed on the cylinder rod of the lifting cylinder 52 to support the workpiece 10 to be heated. A temperature measuring device 6 (such as an infrared temperature measuring device) is also installed on the feeding machine seat 2. The temperature measuring device 6 is opposite to the top of the support seat 51 to monitor the heating state of the workpiece 10 from above.

[0028] A finished product collection box 22 and a waste collection box 23 are also provided on the feeder base 2. The finished product collection box 22 is close to the robot 7, and the finished workpieces that have completed stamping are placed in the finished product collection box 22 by the robot 7; the waste collection box 23 is close to the feeding device 3 and is opposite to the air clamp 361. The robot 7 places the OK workpieces after heating into the mold of the press 9 according to the temperature measurement results, and puts the NG materials into the waste collection box 23.

[0029] The robot 7 is a multi-axis robot, such as a six-axis robot, which is connected to a robot control module 8 (such as an ABB industrial robot control cabinet RC5); a clamping mechanism 71 is installed at the end of the arm of the robot 7, and the robot 7 rotates its arm to enable the clamping mechanism 71 to send the heated workpiece into the press 9 and take the finished workpiece out of the press 9 and put it into the finished product collection box 22.

[0030] The clamping mechanism 71 includes a fixed seat 73, on which a mounting head 72 is arranged, and the entire clamping mechanism 71 is assembled on the arm of the robot 7 through the mounting head 72; the fixed seat 73 is a right-angle bending structure, one end of which is equipped with a finished product cylinder 75, and the other end is equipped with a blank material cylinder 77; the finished product cylinder 75 is connected to a finished product clamp 74, and the finished product cylinder 75 drives the finished product clamp 74 to clamp or open. The blank material cylinder 77 is connected to a blank material clamp 76, and the blank material cylinder 77 drives the blank material clamp 76 to clamp or open.

[0031] During operation, the material (workpiece 10) is first manually placed into the vibration plate 21, and the vibration plate 21 starts to work and vibrates to feed the material. After the sensor 310 senses that the workpiece 10 is directly vibrated out of the vibration plate 21 and reaches the discharge position as the transfer position, the feeding cylinder 39 drives the discharge seat 38 to divide the workpiece 10, and then the Z-axis cylinder 32, the X-axis cylinder 34 and the material transfer cylinder 36 cooperate to move the workpiece 10 to the support seat 51 as the position to be heated by the air clamp 361. The lifting cylinder 52 descends, and the workpiece 10 enters the range of the induction heating coil 41 of the high-frequency heating device 4, and starts to work to heat the workpiece 10. After the heating is completed, the temperature measuring device 6 measures the temperature of the workpiece 10. Then the lifting cylinder 52 rises, and the robot 7 uses the blank clamp 76 at the end to clamp the heated workpiece 10, and according to the temperature measurement result, the OK workpiece after heating is placed in the mold of the press 9, and the NG material is placed in the waste collection box 23.

[0032] In addition, in the press machine, a mold monitor or a high-precision distance-measuring laser sensor is used to detect whether the workpiece on the mold is in place; if it is in place, the next process is carried out, and if it is not in place, an alarm is given. The press machine 9 performs stamping and forming on the workpiece, and after stamping and forming, the robot 7 takes out the finished product through the finished product fixture 74 at the end and places it in the finished product collection box 22. Finally, a bamboo tube is used to blow and clean the mold.

The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
