[0002] On the door production line, workers need to use a variety of tools when they are working. In order not to interfere with the normal operation of the door production line, the location where the tools are placed is a certain distance away from the door production line. When workers need tools, they need to walk from the door production line to the location where the tools are placed to get the tools, and then walk back to the door production line. After using the tools, workers are required to walk from the door production line to the location where the tools are placed, and after placing the tools, they walk back to the door production line. During the whole process, workers need to go back and forth between the door production line and the tool placement four times to use a tool, which reduces the efficiency of workers in using tools and increases their workload. Therefore, it is necessary to set up a tool placement device to improve work efficiency. In addition, the trend of less-manned and unmanned manufacturing industry has gradually extended to automobile production.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0022] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:
[0023] Example 1
[0024] like Figure 1 As shown, a light-sensitive mobile material conveying device comprises a fixed structure 1, a guide rail structure 2, a workbench 3, a driving mechanism 4 and a light sensor 5; the guide rail structure 2 is suspended below the fixed structure 1, the workbench 3 is suspended below the guide rail structure 2 and is slidably connected to the guide rail structure 2; the driving mechanism 4 is installed on the top of the workbench 3 and contacts the guide rail structure 2 to drive the workbench 3 to move along the length direction of the guide rail structure 2, and the light sensor 5 is installed on the workbench and is electrically connected to the driving mechanism 4 to control the movement of the driving mechanism 4. The fixed structure 1 is an I-beam, which is used to install the light-sensitive mobile material conveying device to a certain position. The I-beam is installed on the wall or ceiling and is difficult to move, so as to ensure the stability of the light-sensitive mobile material conveying device when working. The guide rail structure 2 is hoisted below the fixed structure 1, and the workbench 3 is suspended below the guide rail structure 2, so as to avoid occupying the ground space, and the workbench 3 can move along the guide rail structure 2. A driving mechanism 4 is arranged between the guide rail structure 2 and the workbench 3 to provide power for the workbench 3 to move on the guide rail structure 2. When the worker moves, the worker's position is sensed by the light sensor 5, and the light sensor 5 controls the driving structure 4 to start or stop, so that the workbench 3 automatically moves with the worker and stops at a suitable position.
[0025] like Figure 2As shown, the guide rail structure 2 includes a slide rail 21 and a power rail 22. The slide rail 21 is arranged in parallel with the power rail 22. The slide rail 21 is suspended below the fixed structure 1, and the power rail 22 is installed on one side of the slide rail 21. The upper surface of the power rail 22 is a horizontal plane, and the upper surface of the power rail 22 is in contact with the drive mechanism 4. The slide rail 22 is slidably connected to the workbench 3, and its main functions are to bear the load of the workbench 3, determine the sliding trajectory of the workbench 3, and reduce the friction when the workbench 3 slides, so that it moves more smoothly. The drive mechanism 4 is in direct contact with the guide rail structure 2 to drive the workbench 3 to move along the guide rail structure 2. On the one hand, the slide rail 21 needs to be connected to the fixed structure 1 to fix its own position, and on the other hand, it also needs to be slidably connected to the workbench 3 to provide a track for the sliding of the workbench 3. If the drive mechanism 4 is in contact with the slide rail 21, it is difficult to achieve a reasonable arrangement of the connection parts of the slide rail 21 with other components, which is bound to cause the structure of the connection between the slide rail 21 and other components to be complicated. Therefore, a power rail 22 parallel to the slide rail 21 is set on one side thereof. The power rail 22 is slidably connected to the driving mechanism 4 to bear the motion load when the workbench 3 moves. The structure is simple, which avoids making the slide rail 21 bear too many functions and realizes the reasonable layout of various components.
[0026] like Figure 2 As shown, the slide rail 21 is a double-row tube, which is arranged up and down. The upper tube of the double-row tube is connected to the fixed structure 1, the power rail 22 is installed on the side of the upper tube, and the lower tube of the double-row tube is slidably connected to the workbench 3. The slide rail 21 needs to be connected to the fixed structure 1 and the workbench 3 at the same time, and the workbench 3 is slidably connected. When the workbench 3 slides on the slide rail 21, in order to make the sliding process smooth, it is necessary to ensure that the slide rail 21 has no structure set on the sliding track of the workbench 3. The slide rail 21 also needs to be connected to the fixed structure 1, and a connection point needs to be set, and the connection point must have a physical structure connected to the fixed structure 1. If the connection point is set on the sliding track of the workbench 3, it will inevitably affect the sliding of the workbench 3. In order to avoid the problem of mutual interference between the two, the slide rail 21 is set as a double-row tube structure, one of which is specifically connected to the workbench 3 for sliding, and the other is connected to the fixed structure 1, so as to achieve the separation of the connection parts of the slide rail 21 with the fixed structure 1 and the workbench 3, and avoid mutual interference between the two. The slide rail 21 is suspended below the fixed structure 1, and the workbench 3 is installed below the slide rail 21. The three are arranged up and down in the upper layer of the space. Therefore, the double-row pipe structure of the slide rail 21 is also arranged up and down, the upper pipe is connected to the fixed structure 1, and the lower pipe is connected to the workbench 3.
[0027] like Figure 1As shown, the workbench 3 is a frame structure, the bottom of the workbench 3 is a storage plate 31, one of the sides of the workbench 3 perpendicular to the length direction of the guide rail structure 2 is an open surface, and a slider 32 is installed on the top of the workbench 3, and the slider 32 is slidably connected to the lower tube of the slide rail 21. Since the workbench 3 is suspended below the slide rail 31 and cannot bear excessive load, the workbench 3 is set as a frame structure to reduce the weight of the workbench 3 itself. The tools to be used are placed on the storage plate 31 at the bottom of the workbench 3, and one side of the workbench 3 facing the staff is an open surface, so that the staff can take the tools placed on the storage plate 31 without obstruction. A slider 32 is fixed on the top of the workbench 3, and the slider 32 matches the slide rail 21 and is slidably connected thereto.
[0028] like Figure 2 As shown, a C-shaped groove is provided on the slider 32, the notch of the C-shaped groove is upward, and the C-shaped groove is slidably connected with the lower tube of the slide rail 21; the inner diameter of the C-shaped groove is larger than the diameter of the lower tube of the slide rail 21; the notch width of the C-shaped groove is smaller than the diameter of the lower tube of the slide rail 21; the notch width of the C-shaped groove is larger than the connection between the upper tube and the lower tube of the slide rail 21. The slide rail 21 is a double-row tube structure, and the lower tube connected to the slider 32 has a circular cross-sectional shape, which matches the inner wall surface of the C-shaped groove of the slider 32, ensuring the matching degree between the slider 32 and the slide rail 21, increasing the connection area of the sliding connection between the two, and making the sliding process of the slider 32 on the slide rail 21 more firm and stable. The upper end of the lower tube of the slide rail 21 slidably connected to the slider 32 is provided with a connection part to connect with the upper tube of the slide rail 21, but the connection part occupies a certain space and cannot be used for the slider 32 to slide on the slide rail 21. Therefore, a C-shaped groove structure is provided on the slider 32, and the notch of the C-shaped groove is used to cooperate with the connecting part. The notch width of the C-shaped groove is wider than the width of the connecting part, ensuring that the slider 32 will not interfere with the connecting part during the sliding process.
[0029] like Figure 2 As shown, the driving mechanism 4 includes a motor 41, a driving wheel 42 and a fixing rod 43; the driving wheel 42 is mounted on the output shaft of the motor 41; the driving wheel 42 contacts the plane of the power rail 22, and the motor 41 is fixed to the top of the workbench 3 through the fixing rod 43. When a workbench is needed, only the motor 41 is needed, and the motor 41 will drive the driving wheel 42 to rotate, and the driving wheel 42 contacts the power rail 22. When the driving wheel 42 contacts the power rail 22, friction will be generated, and the driving wheel 42 can roll back and forth on the power rail 22 under the action of the friction. The motor 41 is fixed to the top of the workbench 3 through the fixing rod 43. When the motor 41 moves on the power rail 22 with the driving wheel 42, the motor 41 also pulls the workbench 3 through the fixing rod 43 to move with the movement of the driving wheel 42.
[0030] Example 2
[0031] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 2 As shown, the optical mobile material conveying device also includes a travel limit switch 44. There are two travel limit switches 44. The travel limit switches 44 are installed on the top of the workbench 3 and arranged along the length direction of the guide rail structure 2. The length of the slide rail 21 is limited. If the drive mechanism 4 drives the workbench 3 to move along the slide rail 21 without a limiting device, it is possible that the workbench 3 will slide out of the slide rail 21, causing a derailment accident. In order to ensure the safety of the workbench 3 during the sliding process, two travel limit switches 44 are provided on the top of the workbench 3. The two travel limit switches 44 are respectively arranged at both ends of the workbench 44 to correspond to the two ends of the slide rail 21. When the workbench 3 moves to the end of the slide rail 21, the travel limit switch 44 near the end of the slide rail 21 is triggered, and the drive device 4 is controlled to stop, so that the workbench 3 stops sliding, ensuring that the workbench 3 will not slide out of the slide rail 21.
[0032] like Figure 1 As shown, the light sensor 5 is installed under the workbench 3, and the light sensing part of the light sensor 5 faces the open surface of the workbench 3. The main function of the light sensor 5 is to sense the position of the worker, so as to control the driving mechanism 4 to move with the worker. The open surface of the workbench 3 is provided for the convenience of the worker to take the tools on the workbench 3, and its direction is the direction where the worker is located. Therefore, the light sensing part of the light sensor 5 should face the open surface of the workbench 3 to sense the position of the worker.
[0033] Example 3
[0034] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, it also includes an electric box 6; the electric box 6 is installed on the workbench 3, and the electric box 6 is electrically connected to the motor 41 and the light sensor 5. The main function of the electric box 6 is to process the signal of the light sensor 5 to control the movement of the motor 41.
[0035] like Figure 1 As shown, the light-sensitive mobile material conveying device also includes a button box 7, which is electrically connected to the motor 41. The button box 7 can control the motor 41 to stop driving and return with one button. The button box 7 can control the working state of the light-sensitive mobile material conveying device, which is convenient for the staff to operate. When the staff completes the work, they only need to operate the button box 7 to return the workbench 3 to the initial position, and the staff does not need to lead the workbench 3 to move.
