DETAILED DESCRIPTION

[0033] The following is a detailed description of an AGV material transport vehicle with a protective function of the present invention in conjunction with the accompanying drawings.

[0034] like Figure 1-2As shown, an embodiment of an AGV material transport vehicle with a protective function of the utility model includes a vehicle body 1 and a plurality of movable wheels 2 arranged on the vehicle body 1. The vehicle body 1 can be driven to move by controlling the rotation of the movable wheels 2, so as to move to a designated position for docking with a production line equipment (not shown in the figure); wherein, a support plate 4 is fixedly provided on the top of the vehicle body 1, and a movable frame 5 is horizontally and movably provided on the support plate 4, and a first material receiving mechanism 8 and a second material receiving mechanism 9 that can slide horizontally are installed on the movable frame 5, the first material receiving mechanism 8 and the second material receiving mechanism 9 are arranged side by side and the sliding direction is perpendicular to the sliding direction of the movable frame 5, the first material receiving mechanism 8 and the second material receiving mechanism 9 slide in a direction of approaching or moving away from each other, thereby adjusting the distance between the first material receiving mechanism 8 and the second material receiving mechanism 9 to receive materials of different sizes, so that the material transport vehicle can adapt to the flexibility requirements of the production line equipment (not shown in the figure). Before receiving the material, first control the movable frame 5 to move horizontally on the support plate 4, so that the first material receiving mechanism 8 and the second material receiving mechanism 9 are connected to the discharge position of the production line equipment (not shown in the figure), and the first material receiving mechanism 8 and the second material receiving mechanism 9 are operated at the same time to receive and process the material. After receiving the material to the designated position (the middle of the first material receiving mechanism 8 and the second material receiving mechanism 9), the first material receiving mechanism 8 and the second material receiving mechanism 9 stop transporting, and finally control the movable frame 5 to return to the initial position; under the action of the movable frame 5 being movably set on the support plate 4, the positioning accuracy of the above connection is within the range of 10-20mm.

[0035] When the AGV material transporter is in the process of transporting materials, in order to prevent the AGV material transporter from shaking due to bumps on the road and causing damage to the materials, a shock-absorbing mechanism 3 is installed between each moving wheel 2 and the vehicle body 1. By setting the shock-absorbing mechanism 3, when the AGV material transporter is in the process of transporting materials, the shock-absorbing mechanism 3 performs shock-absorbing treatment on the vehicle body 1, so that the transportation process can be smoother and more stable, and the materials are protected. In addition, in order to control the sliding distance of the movable frame 5 on the support plate 4, a control mechanism 6 for controlling the movement of the movable frame 5 is installed on the support plate 4. When the vehicle body 1 moves to a specified position (close to the discharge position of the production line equipment), the control mechanism 6 is operated to control the movable frame 5 to move on the support plate 4 for a specified distance, so that the first material receiving mechanism 8 and the second material receiving mechanism 9 are connected to the discharge position of the production line equipment (not shown in the figure), and automatic docking is achieved without the need for staff operation.

[0036] Preferably, a protective shell 11 is also provided on the support plate 4 to protect the materials placed on the first material receiving mechanism 8 and the second material receiving mechanism 9. After the first material receiving mechanism 8 and the second material receiving mechanism 9 are operated to receive the materials transported from the discharging position of the production line equipment (not shown in the figure), the movable frame 5 is controlled to reset to drive the materials to be placed in the protective shell 11. In the process of driving the vehicle body 1 to move to transport the materials, the materials are protected under the action of the protective shell 11 to prevent the materials from falling from the vehicle body 1. Further, the protective shell 11 is formed with a feed inlet, and a door panel 12 for blocking it is installed at the feed inlet. The door panel 12 is rotatably arranged on the protective shell 11 through a rotating member 13; the initial state of the door panel 12 is to block the feed inlet of the protective shell 11. When the control mechanism 6 controls the movable frame 5 to move out of the protective shell 11, the movable frame 5 will push the door panel 12 open. Under the action of the protective shell 11 and the door panel 12, the materials in the transportation process are further protected.

[0037] like Figure 3-5 As shown, the control mechanism 6 includes a support frame 61 fixedly arranged on the support plate 4, a slide groove 62 whose length direction is consistent with the sliding direction of the movable frame 5 is formed in the support frame 61, a slider 63 is fixedly arranged on the movable frame 5, and the slider 63 is slidably arranged in the slide groove 62, and the slider 63 slides in the slide groove 62, so that the movable frame 5 slides on the support plate 4. Further, a screw rod 64 whose axial direction is consistent with the sliding direction of the movable frame 5 is arranged in the slide groove 62, and the screw rod 64 is threadedly connected to the slider 63, and a second servo motor 65 whose output shaft is connected to the end of the screw rod 64 is installed on the support plate 4. By running the second servo motor 65 to drive the screw rod 64 to rotate, the slider 63 is driven to slide in the slide groove 62, so that the movable frame 5 moves with the first material receiving mechanism 8 and the second material receiving mechanism 9 towards the direction close to the production line equipment (not shown in the figure) and connects with the discharge position of the production line equipment (not shown in the figure). The first material receiving mechanism 8 and the second material receiving mechanism 9 can be operated at the same time to receive materials, and the distance between the first material receiving mechanism 8 and the second material receiving mechanism 9 can be adjusted to receive materials of different sizes. After receiving the materials, the screw rod 64 is driven to reverse to control the movable frame 5 to reset with the first material receiving mechanism 8 and the second material receiving mechanism 9.

The first material receiving mechanism 8 includes a first transport component 81 and a second transport component 82 which are horizontally slidably provided on the support cross bar 7. The first transport component 81 and the second transport component 82 can slide toward or away from the middle of the movable frame 5 at the same time. In order to control the sliding of the first transport component 81 and the second transport component 82, a first double-axis cylinder 83 is installed on the first transport component 81, and a first telescopic rod is provided on the movable frame 5. The first double-axis cylinder 83 is fixed to the first fixed block 84 with the end of the telescopic rod on the side away from the second transport component 82, and the end of the telescopic rod close to the second transport component 82 is fixed to the second transport component 82 through the first connecting block 85; by running the first double-axis cylinder 83, the telescopic rods at both ends of the first double-axis cylinder 83 are extended at the same time, thereby pushing the first transport component 81 and the second transport component 82 to slide in the direction away from the middle of the movable frame 5, and at the same time, it will also push the second transport component 82 away from the first transport component 81, so that the distance between the first transport component 81 and the second transport component 82 becomes larger.

[0039] In addition, the first material receiving mechanism 8 and the second material receiving mechanism 9 have the same structure, and the movement directions of the two are opposite (that is, the first material receiving mechanism 8 and the second material receiving mechanism 9 move in the direction of approaching or moving away from each other). Specifically, the second material receiving mechanism 9 also includes a third transport component 91 and a fourth transport component 92 horizontally slidably arranged on the support cross bar 7, a second double-axis cylinder 93 is installed on the third transport component 91, and a second fixed block 94 is also provided on the movable frame 5. The end of the telescopic rod of the second double-axis cylinder 93 away from the fourth transport component 92 is fixedly arranged with the second fixed block 94, close to The end of the telescopic rod on one side of the fourth transport component 92 is fixed to the fourth transport component 92 by the second connecting block 95; the first double-axis cylinder 83 and the second double-axis cylinder 93 are operated at the same time, so that the first transport component 81 and the third transport component 91 move in opposite directions at the same time, and the distance between the first transport component 81 and the second transport component 82 becomes larger, and the distance between the third transport component 91 and the fourth transport component 92 will also become larger, so that the material receiving area becomes larger, thereby receiving larger materials, and can also receive materials of different sizes, thereby improving the practicality of the material transport vehicle.

[0040] Preferably, the first transport component 81 includes a sliding frame 811 slidably arranged on the support cross bar 7, and the length direction of the sliding frame 811 is perpendicular to the length direction of the support cross bar 7, wherein a first roller 812 and a second roller 813 are respectively arranged at both ends of the sliding frame 811, the first roller 812 and the second roller 813 are at the same level, and a conveyor belt 814 for receiving and transporting materials is wound around the first roller 812 and the second roller 813, and the conveyor belt 814 can be driven to move by driving the first roller 812 or the second roller 813 to rotate. In addition, a through hole 816 is provided on the sliding frame 811 for the support cross bar 7 to pass through, and under the action of the through hole 816, the sliding frame 811 can slide horizontally on the support cross bar 7. The first transport component 81 has the same structure as the second transport component 82, and operates in the same manner.

[0041] In addition, in order to enable the first transport component 81, the second transport component 82, the third transport component 91 and the fourth transport component 92 to operate simultaneously, a driving mechanism 10 for driving multiple second rollers 813 to rotate is installed on the movable frame 5, wherein the driving mechanism 10 includes a pair of support seats 101 fixedly arranged on the movable frame 5, and a spline shaft 102 whose axial direction is perpendicular to the sliding direction of the movable frame 5 is rotatably provided on the support seat 101, and an axial hole 815 for the spline shaft 102 to pass through is provided on the second roller 813, so that the second roller 813 is sleeved on the spline shaft 102 through the axial hole 815, and the second roller 813 can be driven to rotate by driving the spline shaft 102 to rotate; a third servo motor 103 whose output shaft is connected to the end of the spline shaft 102 is installed on the movable frame 5, and the spline shaft 102 can be driven to rotate by running the third servo motor 103, thereby driving multiple second rollers 813 to rotate simultaneously, and driving the conveyor belt 814 to move for material collection processing.

[0042] like Figure 6-7 As shown, when the movable frame 5 pushes the door panel 12 open, in order to enable the door panel 12 to automatically reset, a torsion spring 14 is provided between the rotating part 13 and the protective shell 11. After the door panel 12 is pushed open, the torsion spring 14 is transported. After the material collection is completed and the movable frame 5 is controlled to reset, under the action of the compressed torsion spring 14, the door panel 12 is reset to block the feed port of the protective shell 11 again.

[0043] In order to facilitate pushing the door panel 12 open, a fixing member 15 (such as Figure 3As shown in the figure, a roller 16 which is axially arranged vertically and used to contact the door panel 12 is rotatably provided on the fixing member 15; when the movable frame 5 is controlled by the control mechanism 6 to move toward the outside of the protective shell 11, the roller 16 contacts the door panel 12, thereby automatically pushing the door panel 12 open, and the friction is reduced under the action of the roller 16. In addition, an antistatic coating 111 is provided on the inner wall of the protective shell 11. During the transportation of materials, the materials are placed in the protective shell 11. During the protection of the materials by the protective shell 11, the antistatic treatment can also be performed by the antistatic coating 111. The antistatic level of the antistatic coating 111 is between 10^6-10^9 to prevent the parts from being damaged by static electricity.
