[0028] To make the technical means, creative features, and achieved objectives and effects of this utility model readily understandable, the present utility model will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] To address the shortcomings of existing technologies, such as Figure 1 - Figure 7 As shown, this utility model provides a mold conveying device for an AGV vehicle. The conveying device is used to convey the mold 7 to a testing device for testing. It includes: an AGV vehicle body 1 and a carrier box 2 installed on the AGV vehicle body 1. A partition 3 is provided in the vertical direction inside the carrier box 2. A lifting mechanism 4 is provided on one side of the partition 3. Two conveying mechanisms 5 for storing and conveying the mold 7 are respectively provided above and below the lifting mechanism 4.

[0030] The lifting mechanism 4 includes a drive assembly 52, a lifting plate 44, a fixed plate 45, two reciprocating screws 46, and two support rods 48. The drive assembly 52 is fixedly installed at the bottom of the inner wall of the bearing housing 2. The drive assembly 52 is used to drive the two reciprocating screws 46 to rotate. The upper end of the reciprocating screw 46 is rotatably connected to the top of the inner wall of the bearing housing 2. A screw nut 47 is fitted on the reciprocating screw 46. The outer side of the screw nut 47 is fixedly connected to two opposite corners of the lifting plate 44. The four corners of the lifting plate 44 are fixedly connected to the bottom of the fixed plate 45 by four fixed rods 410. Two sleeves 49 are fixedly connected to the other two opposite corners of the lifting plate 44. Two support rods 48 are movably installed in the two sleeves 49. The upper and lower ends of the support rods 48 are fixedly connected to the upper and lower ends of the inner wall of the bearing housing 2.

[0031] Specifically, the drive assembly 52 includes a dual-axis motor 41 and two worm gear reducers 42. The bottom ends of the dual-axis motor 41 and the two worm gear reducers 42 are fixedly connected to the bottom end of the inner wall of the bearing housing 2. The two output ends of the dual-axis motor 41 are respectively connected to the input ends of the two worm gear reducers 42 through two rotating shafts 43. The output ends of the two worm gear reducers 42 are respectively fixedly connected to the bottom ends of two reciprocating screws 46.

[0032] It should be noted that when the mold 7 is transported to the testing device, the mold 7 to be tested is placed on the lower conveyor mechanism 5, and the AGV moves to the corresponding position. At this time, the upper conveyor mechanism 5 is aligned with the testing port of the testing device. The upper conveyor mechanism 5 receives and carries the mold 7 that has been tested in the testing device. The dual-axis motor 41 drives the worm gear reducer 42, which in turn drives the two reciprocating screws 46 to rotate. Through the screw nut 47 that cooperates with it, the lifting plate 44 moves up and down along the support rod 48, thereby adjusting the height of the lower conveyor mechanism 5 located on the lifting plate 44, so that the lower conveyor mechanism 5 is aligned with the height of the testing port. The mold 7 to be tested is transported to the testing device for quality inspection through the lower conveyor mechanism 5. Then the AGV moves and transports the tested mold 7 to the next production line and reloads the new mold 7 to be tested, and starts a new work cycle. At the same time, the height of the lifting plate 44 can be adjusted to realize the conveying and docking of different production lines, which can flexibly cope with production lines and testing devices of different heights.

[0033] Specifically, the two conveying mechanisms 5 are respectively mounted on the lifting plate 44 and the fixed plate 45;

[0034] The conveying mechanism 5 includes a carrying tray 51, a driving component 52, and a pushing component 53. The carrying tray 51 is mounted on the lifting plate 44 / fixed plate 45 via the driving component 52. The driving component 52 is used to drive the carrying tray 51 to slide on the lifting plate 44 / fixed plate 45. A pushing component 53 for pushing material onto the mold 7 is provided on one side of the upper end of the carrying tray 51.

[0035] Specifically, the drive assembly 52 includes a horizontal guide rail 521 and two linear slide rails 524. The horizontal guide rail 521 is mounted on the lifting plate 44 / fixed plate 45. A horizontal slider 522 is mounted on the horizontal guide rail 521. A drive motor 523 for driving the horizontal slider 522 to slide on the horizontal guide rail 521 is mounted on one side of the horizontal guide rail 521. The upper end of the horizontal slider 522 is fixedly connected to the bottom end of the support tray 51. The two linear slide rails 524 are both mounted on the lifting plate 44 / fixed plate 45 and are located on both sides of the horizontal guide rail 521. At least one linear slide rail slider 525 is slidably mounted on the linear slide rail 524. The upper end of the linear slide rail slider 525 is fixedly connected to the bottom end of the support tray 51.

[0036] It should be noted that the drive motor 523 drives the carrier tray 51 to move on the horizontal guide rail 521, and the cooperation of the linear slide rail 524 and the linear slide block 525 ensures that the carrier tray 51 remains horizontal and stable during the sliding process.

[0037] Specifically, the pushing assembly 53 includes a linear guide rail 531, which is mounted on the support tray 51. A guide rail slider 532 is slidably mounted on the linear guide rail 531. A servo motor 533 for driving the guide rail slider 532 to slide on the linear guide rail 531 is mounted on one side of the linear guide rail 531. A first electromagnet 534 is fixedly connected to the end of the guide rail slider 532. A connecting rod is mounted on the upper end of the guide rail slider 532. A second electromagnet 535 is fixed to one end of the connecting rod. The first electromagnet 534 and the second electromagnet 535 are used to push and attract the mold 7.

[0038] It should be noted that when the mold 7 needs to be pushed out of the support tray 51, the servo motor 533 starts, driving the guide rail slider 532 to slide smoothly along the linear guide rail 531; the end of the guide rail slider 532 is fixedly connected to the first electromagnet 534, and the upper end of the guide rail slider 532 is provided with a connecting rod, one end of which is fixed to the second electromagnet 535. At this time, the second electromagnet 535 and the first electromagnet 534 are in a de-energized state, and provide additional pushing force to the mold. When the mold 7 completely leaves the support tray 51 and enters the detection device or other equipment, the servo motor 533 stops working, and the guide rail slider 532 stops at the end position. After the pushing operation is completed, the servo motor 533 starts again to reset the guide rail slider 532; when the mold 7 needs to be received from the production line or detection device, the drive motor 523 drives the support tray 51 to slide horizontally through the horizontal guide rail 521 and the linear slide rail 524. The support tray 51 slides outward, and the first electromagnet 534 and the second electromagnet 535 are energized to receive and attract the mold 7 to be received;

[0039] Specifically, a position sensor 6 is provided on the outer wall of the carrying tray 51. The position sensor 6 is set in a direction parallel to the direction of the linear guide rail 531. The position sensor 6 is used to monitor the position of the tray in real time. The position sensor 6 is connected to the controller. When the carrying tray 51 slides to a predetermined position, the position sensor 6 will send a signal to the controller, which will trigger the action of the pushing component 53.

[0040] In summary, the basic working principle of this utility model is as follows: When the mold 7 needs to be sent into the testing device, the mold 7 to be tested is first placed on the carrying tray 51 of the lower conveying mechanism 5 located on the lifting plate 44. The AGV moves to the corresponding position. At this time, the lower conveying mechanism 5 on the fixed plate 45 is aligned with the testing port of the testing device. The drive motor 523 drives the carrying tray 51 to slide horizontally through the horizontal guide rail 521 and the linear slide rail 524. The carrying tray 51 slides outward, and the first electromagnet 534 and the second electromagnet 535 are energized. After receiving and adsorbing the mold 7 that has been tested, the carrying tray 51 is reset. The dual-axis motor 41 drives the worm gear reducer 42, which in turn drives the two reciprocating screws 46 to rotate. Through the screw nut 47 that cooperates with it, the lifting plate 44 moves up and down along the support rod 48. The moving fixed plate 45 rises to the height of the inspection port; at this time, the drive motor 523 and the servo motor 533 start at the front and rear respectively, the carrying tray 51 slides along the linear slide rail 524, and the guide rail slider 532 slides along the linear guide rail 531. The mold 7 to be inspected is smoothly pushed from the carrying tray 51 into the inspection device by the first electromagnet 534 and the second electromagnet 535, which are in a de-energized state; after the conveying is completed, the AGV moves to the next production line, unloads the inspected mold 7, and reloads the new mold 7 to be inspected, and starts a new round of work cycle; throughout the process, the position sensor 6 monitors the position of the carrying tray 51 to ensure the reliability of the mold 7 conveying and inspection process. This device enhances the flexibility and adaptability of mold conveying to a certain extent and can flexibly cope with production lines and inspection devices of different heights.
