DETAILED DESCRIPTION

[0019] The technical solutions of the present application will be further described in detail below in conjunction with preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work shall fall within the scope of protection of the present application.

[0020] Please refer to Figures 1-12 , the present application provides technical solutions: a feeding device for motor cover, comprising a feeding system 1, a first mechanical arm 2, a second mechanical arm 7 and an external controller, one side of the feeding system 1 is provided with a placing rack 6, the placing rack 6 is used for storing unqualified motor cover, the feeding system 1 comprises a mounting frame 14, both ends of the mounting frame 14 are provided with roller shafts 12, both ends of the roller shafts 12 are fixedly connected with rotating rods 11, both ends of the rotating rods 11 are sleeved with a conveyor belt 13; The adjusting assembly is arranged in the conveyor belt 13 and is used for preventing the conveyor belt 13 from deforming when feeding the motor cover. The adjusting assembly comprises a mounting frame 5, both ends of the mounting frame 5 are fixedly connected between the inner walls of both sides of the mounting frame 14, the lower side of the conveyor belt 13 is arranged in the interior of the mounting frame 5, the upper surface of the mounting frame 5 is fixedly connected with an adjusting drive 51, the adjusting drive 51 is vertically arranged between the upper surface of the mounting frame 5, the output end of the adjusting drive 51 is fixedly connected with an adjusting plate 52 upwards, the adjusting plate 52 is provided with a mounting groove 521, a pressure sensor 522 is fixedly installed in the interior of the mounting groove 521, the pressure sensor 522 is connected with a controller (not shown in the figure), and the adjusting drive 51 is arranged in three groups in the horizontal direction of the upper surface of the mounting frame 5.

[0021] It should be noted that the adjusting drive 51 can be a pneumatic cylinder, and the first mechanical arm 2 is prior art (such as an industrial mechanical arm), which will not be described in detail herein.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The mounting frame 14 is used for mounting the roller shafts 12, the rotating rods 11 away from the first mechanical arm 2 are fixedly connected between the output shafts of the motors, the rotating rods 11 at both ends of the mounting frame 14 are driven through the way of sleeving a belt (not shown in the figure), so as to drive the conveyor belt 13 to rotate, thereby achieving the purpose of feeding the motor cover.

[0023] The adjusting drive 51 drives the adjusting plate 52 to move vertically by the extension and retraction of the output end thereof. The pressure sensor 522 fixedly connected inside the mounting groove 521 is used to detect the pressure at the position of the conveying belt 13. When the detected value of the pressure sensor 522 at the position exceeds the preset value, in order to prevent the conveying belt 13 at the position from being deformed under the pressure and thus causing the position of the motor cover on the conveying belt 13 to be deviated, the adjusting drive 51 at the position drives the adjusting plate 52 to move vertically upward under the control of the controller until the upper surface of the adjusting plate 52 is adjusted to be in sliding contact with the bottom of the conveying belt 13, and then the conveying belt 13 at the position with excessive pressure is supported by the adjusting plate 52. At the same time, the controller (not shown in the figure) controls the other two adjusting drives 51 in the feeding direction of the motor cover to be adjusted synchronously to prevent the motor cover with excessive weight from deforming the conveying belt 13.

[0024] The auxiliary frame 53 is fixedly connected to the mounting frame 5. The auxiliary frame 53 is arranged in pairs, and two auxiliary frames 53 are symmetrically arranged on the two sides of the adjusting drive 51. The auxiliary frame 53 is provided with a cavity 531. The first spring 535 is fixedly connected in the auxiliary frame 53. The sliding plate 532 is slidingly connected in the auxiliary frame 53.

The other end of the first spring 535 is fixedly connected to the lower surface of the sliding plate 532. The connecting column 534 is fixedly connected to the upper surface of the sliding plate 532. The top of the connecting column 534 is fixedly connected to the lower surface of the adjusting plate 52. The limiting plate 533 is fixedly connected to the auxiliary frame 53. The limiting plate 533 is slidingly connected with the connecting column 534. Ventilation holes 536 are formed in the four sides of the auxiliary frame 53.

[0025] Reference Figure 4 and Figure 5 The connecting column 534 fixedly connected to the sliding plate 532 can assist in supporting the adjusting plate 52 when the adjusting plate 52 moves up and down, so that the stress on the adjusting plate 52 is more uniform, and the inclination of the adjusting plate 52 due to uneven stress is prevented. When the adjusting plate 52 moves vertically downward, the adjusting plate 52 drives the connecting column 534 to move vertically downward. At this time, the first spring 535 inside the auxiliary frame 53 is deformed under pressure. The sliding plate 532 moves downward in the auxiliary frame 53. The sliding plate 532 expels the air in the auxiliary frame 53 to the outside through the ventilation holes 536. The air expelled to the outside of the auxiliary frame 53 can flow to a certain extent inside the conveying belt 13, thereby assisting in heat dissipation of the inner wall of the conveying belt 13 and also playing a certain buffering role for the vibration of the conveying belt 13 to a certain extent, thereby reducing the vibration amplitude of the conveying belt 13, so as to ensure that the position of the motor cover on the conveying belt 13 is relatively stable.

If the hole position of the motor cover can be inserted into the straight rod part of the standard rod 35 and has no contact with the tapered rod part, the hole position parameter of the motor cover is qualified; If the hole position of the motor cover can be inserted into the straight rod part of the standard rod 35, but the bottom of the motor cover has contact with the tapered rod part: When the lowest point of the contact line between the bottom of the motor cover and the cone rod is between the two groups of laser sensors 322 on the same side, the hole position of the motor cover is within the qualified range, and the feeding can continue; When the lowest point of the contact line between the bottom of the motor cover and the cone rod is below the lowest point of the two groups of laser sensors 322 on the same side, the hole position of the motor cover is too large and exceeds the qualified range, and then the first mechanical arm 2 is moved to the waste area for centralized treatment through the controller (not shown in the figure). The front cover jacking unit includes a second drive 33, which is vertically arranged between the bearing plate 32. The output end of the second drive 33 is fixedly connected with a jacking plate 331.
