[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. The "up", "down", "front", "back", "left", "right" and the like used in the mounting position or direction of the structure or parts of the present embodiment are based on the orientation of the given drawings. They are only for convenience of description and to distinguish the relative positions of the parts or directions, and do not represent the orientation of the equipment or parts when used.

[0028] As shown in Figures 1 to 13 The embodiments of the present application provide a brake pad frame type mold hot pressing automatic equipment, which comprises a frame type structure 1, a support structure 2, a feeding area 3, a standby area 4, a feeding machine 5, a weighing machine 6, a storage hopper 7, a dust collector 8, a pressing machine 9 and a product collecting rack 11. The dust collector 8 is arranged on the left side of the frame type structure 1, the pressing machine 9 is arranged on the right side of the frame type structure 1, and the product collecting rack 11 is arranged on the right side of the pressing machine 9. The support structure 2 is arranged on the outside of the frame type 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 with the inlet of the dust collector 8 through a hose. The feeding area 3 is located at the middle position of the frame type structure 1, the standby area 4 is located at the top position of the frame type structure 1, the standby area 4 is connected with the weighing machine 6, and the standby area 4 and the feeding area 3 are both provided with a material box. The feeding machine 5 is arranged on the front side of the frame type structure 1, and the top end of the feeding machine 5 is connected with the inlet of the storage hopper 7.

[0029] When the feeding machine 5 is used to deliver the mixture to the storage hopper 7, the dust remover 8 works simultaneously to prevent dust overflow and ensure the workshop environment. When the storage hopper 7 is full, the weighing machine 6 is started to prepare the corresponding weight of mixture in the material box in the standby area 4. The material box in the feeding area 3 is lifted to take the mixture in the standby area 4. At this time, the weighing machine 6 continues to work to ensure that the standby area 4 is always full of the first feeding amount. After the press 9 is completed, the ejection and feeding actions are performed. The semi-finished product is temporarily stored in the product collection rack 11. After the feeding is completed, the press 9 works. In this way, the cycle of one process is completed, that is, the feeding-weighing-ejection-waste removal-mold release agent spraying-feeding action.

[0030] As shown in Figure 2 , when the feeding machine 5 works, the dust remover 8 works simultaneously to create a certain negative pressure in the storage hopper 7 and the dust cover through the connected hose to prevent dust from overflowing.

[0031] As shown in Figure 3 and Figure 4 , the weighing machine 6 is a double-weighing structure. The material box 4-1 below the weighing machine 6 is a 6-slot integral structure with 3 rows and 2 columns. The feeding rack 4-2 is arranged on both sides of the standby area 4. The standby area 4 takes the weighing area in turn and is transported by the feeding rack 4-2.

[0032] As shown in Figure 5 , the standby area 4 only has left and right actions to take the weighing area and return to the standby area. The feeding rack 4-2 reaches the standby area 4 to take the material, the mold 10 of the press 9 takes the piece, and the feeding position through the screw lifter 4-4. The feeding rack 4-2 enters the mold 10 to complete the feeding through the ball screw 4-3 transmission.

[0033] As shown in Figure 6 , the feeding rack 4-2 enters the mold 10 to feed through the belt module 12 to provide power, open the plug-in door, and close the plug-in door after feeding. The feeding rack 4-2 is nested with a group of ejection small arms 15 on the inside to maintain the distance between the nozzle and the material box when taking the piece and spraying the mold release agent. The power source of the ejection small arm 15 is the electric cylinder 17 installed on the inside of the feeding rack 4-2.

[0034] As shown in Figure 7 and Figure 8 , the ejection small arm 15 is first stretched out when pushing the piece. The power of the pushing plate 14 relies on the feeding rack 4-2 to push out the ejection product. When it retreats, the program opens the electromagnetic valve of the mold release agent blowing to clean the mold 10. The feeding rack is retracted, and the ejection small arm 15 is retracted. At this time, the mold frame of the mold 10 is raised, and the feeding rack enters the mold 10 again to feed.

[0035] As shown in Figure 9 , Figure 10 and Figure 11As shown, the frame 16 in the mold 10 has 2 axes, the frame 16 has 4 stations, the No. 1 station and the No. 2 station are a group, the No. 3 station and the No. 4 station are another group, and the frame 16 moves left and right to take the upper and lower products, respectively, and the left and right switching reaches the ejection position, and the servo cylinder 18 controls the frame 16 to reach the first and second layers of the mold 10.

[0036] As shown in Figure 12 and Figure 13 The electrical part: the control circuit design, the main control PLC uses the Xunjie XD series, the PLC output point is directly connected to the intermediate relay, solenoid valve, servo driver in the actuator to form a control loop; the host computer uses the Xunjie touch screen, which can display device working state information, input various process parameters. The program part: the PLC control program and the touch screen host computer configuration picture are independently developed, and the hardware uses the Xunjie XD series PLC and the Xunjie touch screen.

[0037] So far, the brake pad frame type mold hot pressing automatic equipment has been developed and put into trial use, and basically achieves the expected design effect. After the operator inputs related parameters such as feeding weight, mold taking position, feeding position and the like on the touch screen, only needs to press the start button, and the equipment is automatically operated, and the positioning accuracy is measured within 0.2 mm.

[0038] Although the present application has been disclosed as above with preferred embodiments, the above preferred embodiments are not intended to limit the present application, and those skilled in the art can make various modifications and modifications without departing from the spirit and scope of the present application, therefore the protection scope of the present application is subject to the scope defined by the claims.
