[0028] like Figures 1 to 13 As shown, an embodiment of the present invention provides a brake pad frame mold hot pressing automation equipment, including a frame structure 1, a support structure 2, a feeding area 3, a waiting area 4, a feeder 5, a weighing machine 6, a storage hopper 7, a dust collector 8, a press 9 and a product collection rack 11. The dust collector 8 is arranged on the left side of the frame structure 1, the press 9 is arranged on the right side of the frame structure 1, and the product collection rack 11 is arranged on the right side of the press 9. The support structure 2 is arranged on the outside of the frame structure 1; the weighing machine 6 is arranged on the top of the support structure 2, the storage hopper 7 is arranged above the weighing machine 6, and the top interface of the storage hopper 7 is connected to the inlet of the dust collector 8 through a hose. The feeding area 3 is located in the middle position of the frame structure 1, the waiting area 4 is located at the top position of the frame structure 1, the waiting area 4 is connected to the weighing machine 6, and the waiting area 4 and the feeding area 3 are both provided with a material box. The feeder 5 is arranged on the front side of the frame structure 1, and the top of the feeder 5 is connected to the inlet of the storage hopper 7.

[0029] When the feeder 5 is used to transport the mixed material to the storage hopper 7, the dust collector 8 works in conjunction with the feeding to prevent dust from overflowing and ensure the working environment of the workshop. After the storage hopper 7 is filled with material, the weighing machine 6 is turned on to prepare the corresponding weight of mixed material in the material box in the waiting area 4. The material box in the feeding area 3 rises to receive the mixed material in the waiting area 4. At this time, the weighing machine 6 continues to work to ensure that the waiting area 4 is always fully prepared with the feeding amount. After the press machine 9 completes the pressing and opening of the mold, the sheet taking and feeding actions are performed. The taken out semi-finished products are temporarily stored in the product collection rack 11. After the feeding is completed, the press machine 9 works, and this cycle is repeated. The feeding-weighing-sheet taking-waste cleaning-spraying release agent-feeding actions are completed in one process.

[0030] like Figure 2 As shown, when the feeder 5 is working, the dust collector 8 works in conjunction with it, and creates a certain negative pressure in the storage hopper 7 and the dust cover through the connected hose to ensure that dust does not overflow.

[0031] like Figure 3 and Figure 4 As shown, the weighing machine 6 is a double-weighing structure, and the material box 4-1 below the weighing machine 6 is a 6-slot overall structure with 3 rows and 2 columns. Feeding racks 4-2 are provided on both sides of the waiting area 4. The waiting area 4 receives the weighed materials in sequence through the ball screw 4-3, and the received materials wait in the set waiting area 4 for transportation by the feeding rack 4-2.

[0032] like Figure 5 As shown, the waiting area 4 has only left and right movements to receive the weighing area and return to the waiting area. The feeding rack 4-2 reaches the waiting area 4 to receive the material, the first / second layer of the mold 10 of the press machine 9, and the feeding position through the screw lifter 4-4. The feeding rack 4-2 enters the mold 10 through the ball screw 4-3 to complete the feeding.

[0034] like Figure 7 and Figure 8 As shown, when pushing the sheet, the sheet-taking arm 15 is extended first, and the power of the sheet-pushing plate 14 is relied on the feeding rack 4-2 to push the sheet-taking product forward. When retreating, the program opens the solenoid valve for spraying the demoulding agent, and the mold 10 is cleaned and sprayed with the demoulding agent. After the feeding rack is retracted, the sheet-taking arm 15 is retracted again. At this time, the mold frame of the mold 10 rises and the feeding rack enters the mold 10 again to feed the material.

[0035] like Fig. 9 , Fig.10 and Fig.11As shown, the film-taking rack 16 in the mold 10 has 2 axes and 4 workstations, namely, workstation 1 and workstation 2 form a group, and workstation 3 and workstation 4 form another group, which respectively receive the upper and lower products. The film-taking rack 16 moves left and right into 2 workstations, among which workstation 1 and workstation 2 occupy one process position, and workstation 3 and workstation 4 occupy one process position. It switches left and right to reach the film-taking position, and the servo electric cylinder 18 controls the film-taking rack 16 to reach the first and second layers of the mold 10 up and down.

[0036] like Fig.12 and Fig.13 As shown, electrical part: control circuit design, the main control PLC adopts Xinjie XD series, the PLC output point is directly connected to the actuator intermediate relay, solenoid valve, servo driver to form a control loop; the host computer adopts Xinjie touch screen, which can display the working status of the equipment and input various process parameters.
