Description

Technical Field

[0001] This invention relates to the field of image acquisition equipment technology, and in particular to a workstation identification device for industrial production based on intelligent sensors. Background Technology

[0002] In workpiece manufacturing, the shape of the workpiece needs to be inspected. The inspection method involves manually placing the workpiece on a smart sensor at a specific workstation for image data acquisition and inspection, thereby determining whether its shape meets the standards in the corresponding positions. Since most workpieces have multiple faces, multiple workstations with smart sensors are required for inspection. In this continuous, assembly-line inspection process, workpieces need to be transported using carriers. To ensure the smart sensors have sufficient time for identification, the assembly line needs to be intermittently shut down and restarted each time a workpiece is moved to a different workstation, reducing inspection efficiency.

[0003] To address the aforementioned issues, we propose an industrial production workstation identification device based on intelligent sensors. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the background art by proposing an industrial production workstation identification device based on intelligent sensors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an industrial production workstation identification device based on intelligent sensors, including a conveyor table, a conveyor channel provided on the conveyor table, a conveyor belt installed in the conveyor channel, multiple intelligent sensors being installed horizontally at equal intervals on the upper end of the conveyor table, trapezoidal blocks being fixedly connected to the front and rear inner walls of the conveyor channel at corresponding positions of each intelligent sensor, toothed plates being fixedly connected to the rear inner wall of the conveyor channel between every two trapezoidal blocks, and multiple transport vehicles being evenly spaced on the conveyor belt;

[0006] The transport vehicle includes a movable base located at the upper end of the conveyor belt. Four support sleeves are evenly fixedly connected to the upper end of the movable base. A sliding support rod is slidably inserted into each of the support sleeves. A vehicle platform is fixedly connected to the upper end of each of the sliding support rods. A rotating plate is rotatably connected to the center of the vehicle platform. A drive assembly is provided at the lower end of the vehicle platform.

[0007] Both ends of the platform are fixedly connected to U-shaped frames. A sliding rod is fixedly connected between the left and right inner walls of the U-shaped frame. A buffer plate is slidably sleeved on the sliding rod. A second spring is fixedly connected between the buffer plate and the right inner wall of the U-shaped frame. A movable opening is provided at the end of the U-shaped frame away from the platform. A movable rod is slidably connected through the movable opening. One end of the movable rod is fixedly connected to the corresponding U-shaped frame, and the other end is rotatably connected to a roller. The position of the roller corresponds to that of the trapezoidal block.

[0008] In the above-mentioned industrial production workstation identification device based on intelligent sensors, each of the support sleeve rods has a vertically opened limit sliding opening on both side walls, and a limit slider is slidably connected in each limit sliding opening. Each limit slider is fixedly connected to a corresponding sliding support rod. Each sliding support rod has an installation groove at its lower end. A first spring is fixedly connected between the top wall of the installation groove and the bottom wall of the support sleeve rod. Each support sleeve rod has a buffer washer fixedly connected at its upper end, and the buffer washer is sleeved on the corresponding sliding support rod.

[0009] In the aforementioned industrial production workstation identification device based on intelligent sensors, the driving component includes a mounting plate fixedly connected to the lower end of a carrier platform. A rotating rod is vertically and rotatably connected through the mounting plate. The upper end of the rotating rod is fixedly connected to the axis of the rotating plate, and a worm gear is fixedly sleeved at the lower end. A worm is meshed with the right side of the worm gear. An extension plate is fixedly connected to the rear end of the mounting plate. A shaft is rotatably connected through the rear side of the extension plate. A gear is fixedly sleeved at the upper end of the shaft, and a first bevel gear is fixedly sleeved at the lower end. A second bevel gear is vertically meshed at the front end of the first bevel gear. A transmission rod is fixedly connected between the second bevel gear and the worm.

[0010] In the above-mentioned industrial production workstation identification device based on intelligent sensors, a limiting frame is fixedly connected to the upper end of the carrier platform, and an anti-slip coating is provided on the upper end of the rotating plate.

[0011] In the aforementioned industrial production workstation identification device based on intelligent sensors, the movable base has two mounting slots, each containing a mounting block. The lower end of each mounting block is fixedly connected to a conveyor belt. Two mounting blocks on the same movable base have telescopic grooves on opposite sides. A movable block is slidably connected within the telescopic groove. A third spring is fixedly connected between the end of the movable block away from the mounting slot and the inner wall of the telescopic groove. A limit block is fixedly connected to the end of the movable block away from the third spring. A limit slot is provided on each mounting block at a corresponding position within the telescopic groove. The end of the limit block away from the movable block is inserted into the corresponding limit slot.

[0012] In the above-mentioned industrial production workstation identification device based on intelligent sensors, the front end of the movable base is provided with a movable port communicating with the telescopic groove at the corresponding position of each telescopic groove. A movable rod is slidably connected in each movable port. The movable rod is fixedly connected to the front end of the corresponding movable block. A vertically arranged pull rod is fixedly connected to the end of each movable rod away from the movable block.

[0013] Compared with existing technologies, the advantages of this intelligent sensor-based industrial workstation identification device are:

[0014] By setting up a liftable transport vehicle and utilizing the continuous transport of the conveyor belt, the transport vehicle moves upwards during its movement by contacting the trapezoidal blocks on the inner walls of the conveying channel with its front and rear rollers. This moves the vehicle to the detection position of the intelligent sensor at the designated workstation. When it moves to the position between two workstations, the gears and toothed plates on the drive assembly mesh and rotate. Through the combined transmission of the first and second bevel gears, the transmission rod, and the worm gear and worm, the rotating rod is driven to rotate at a certain angle, thus rotating the rotating plate. This causes the workpiece to face the rear end of the surface to be inspected. The rotation angle can be controlled by the length of the toothed plate. When moving to the next workstation, the surface facing the intelligent sensor changes, allowing for the inspection of multiple surfaces at different angles. The process is fully automated and requires no manual operation, greatly improving the workpiece inspection efficiency.

[0015] By setting up mounting ports and mounting blocks, the transport vehicle can be directly installed on the conveyor belt simply by aligning the mounting ports on the mobile base with the mounting blocks on the conveyor belt. When disassembling, simply pull the two levers inward to remove the transport vehicle from the conveyor belt. The installation and disassembly process of the vehicle platform is simple and convenient. Attached Figure Description

[0023] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0024] Example 1

[0025] Reference Figure 1-6 An industrial production workstation identification device based on intelligent sensors includes a conveyor table 1 with a conveyor channel and a conveyor belt 2 installed within it. The conveyor channel and conveyor belt 2 form an assembly line for transportation. Multiple intelligent sensors 3 are installed horizontally at equal intervals on the upper end of the conveyor table 1, with each intelligent sensor 3 serving as a detection station. The intelligent sensors 3 are existing technology, utilizing image data acquisition for detection. Trapezoidal blocks 4 are fixedly connected to the inner walls of the front and rear sides of the conveyor channel at corresponding positions of each intelligent sensor 3. Toothed plates 5 are fixedly connected to the inner wall of the rear side of the conveyor channel between every two trapezoidal blocks 4. Multiple transport carriers 6 are evenly spaced on the conveyor belt 2, which are used to place the workpieces to be detected and then transport them through the conveyor channel using the conveyor belt 2, sequentially passing through each identification station.

[0026] The transport carrier 6 includes a movable base 7 located at the upper end of the conveyor belt 2. Four rectangularly distributed support sleeves 8 are fixedly connected to the upper end of the movable base 7. Each support sleeve 8 has a sliding support rod 10 slidably inserted inside. The upper end of each sliding support rod 10 is fixedly connected to a carrier platform 9. The carrier platform 9 can move up and down through the sliding support rods 10. A rotating plate 16 is rotatably connected to the center of the carrier platform 9. The rotating plate 16 is used to place the workpiece. Each support sleeve 8 has a vertically opened limit sliding opening 11 on both sides. Each limit sliding opening 11 has a slidably connected limit slider 12. Each limit slider 12 is fixedly connected to the corresponding sliding support rod 10 to limit the movement and ensure that the sliding support rod 10 does not move out of the support sleeve 8. Each sliding support rod 10 has a mounting groove 13 at its lower end. A first spring 14 is fixedly connected between the top wall of the mounting groove 13 and the bottom wall of the support sleeve 8. The first spring 14 is a tension spring, which keeps the sliding support rod 10 within the support sleeve 8 when no external force is applied, i.e., the carrier platform 9 is at its lowest position. Each support sleeve 8 has a buffer washer 15 fixedly connected to its upper end. The buffer washer 15 is fitted onto the corresponding sliding support rod 10 and, together with the first spring 14, provides a buffering effect, reducing the impact force and minimizing the impact on the workpiece when the carrier platform 9 moves up and down.

[0027] U-shaped frames 27 are fixedly connected to both the front and rear ends of the carrier platform 9. A sliding rod 28 is fixedly connected between the left and right inner walls of the U-shaped frame 27. A buffer plate 29 is slidably sleeved on the sliding rod 28. A second spring 30 is fixedly connected between the buffer plate 29 and the right inner wall of the U-shaped frame 27. A movable opening is provided at the end of the U-shaped frame 27 away from the carrier platform 9. A movable rod 31 passes through and is slidably connected to the movable opening. One end of the movable rod 31 is fixedly connected to the corresponding U-shaped frame 27, and the other end is rotatably connected to a roller 32. The roller 32 corresponds to the position of the trapezoidal block 4. When the conveyor belt 2 drives the transport carrier 6 carrying the workpiece to each workstation, the two... Rollers 32 are in contact with the two trapezoidal blocks 4 at the corresponding workstations. The buffer plate 29 and the second spring 30 effectively reduce the impact of the rollers 32 when they contact the trapezoidal blocks 4. Then, the rolling contact between the rollers 32 and the trapezoidal blocks 4 can be used to move the carrier platform 9 upward, and then the sliding support rod 10 moves upward, stretching the first spring 14. At the same time, the tension of the first spring 14 can be used to ensure that the rollers 32 always roll in contact with the trapezoidal blocks 4. When the carrier platform 9 moves to the highest position, it is exactly at the detection position of the intelligent sensor 3 to perform detection work. The detection process does not need to be stopped, and the conveyor belt 2 can continue to work, improving the detection efficiency.

[0028] A drive assembly is provided at the lower end of the platform 9. The drive assembly includes a mounting plate 18 fixedly connected to the lower end of the platform 9. A rotating rod 19 is vertically passed through and rotatably connected to the mounting plate 18. The upper end of the rotating rod 19 is fixedly connected to the axis of the rotating plate 16, and the lower end is fixedly sleeved with a worm gear 20. A worm 21 meshes with the right side of the worm gear 20. An extension plate 22 is fixedly connected to the rear end of the mounting plate 18. A shaft is passed through and rotatably connected to the rear side of the extension plate 22. A gear 23 is fixedly sleeved at the upper end of the shaft, and a first bevel gear 24 is fixedly sleeved at the lower end. A second bevel gear 25 is vertically meshed at the front end of the first bevel gear 24. The second bevel gear 25 and the worm gear 21 mesh vertically with the first bevel gear 24. A transmission rod 26 is fixedly connected between the rods 21. Whenever the transport carrier 6 passes through a station for inspection and moves between two stations, the carrier platform 9 is at its lowest position. During the movement, the gear 23 meshes with the toothed plate 5 and rotates. Under the combined transmission action of the first bevel gear 24 and the second bevel gear 25, the transmission rod 26, and the worm gear 20 and the worm 21, the rotating rod 19 is driven to rotate at a certain angle, so that the rotating plate 16 rotates at a certain angle, thereby causing the workpiece to face the other side to be inspected towards the rear end. The rotation angle can be controlled by the length of the toothed plate 5, so that multiple surfaces at different angles can be inspected.

[0029] The upper end of the carrier platform 9 is fixedly connected to a limit frame 33, and the upper end of the rotating plate 16 is provided with an anti-slip coating 17. The limit frame 33 plays a protective role to prevent the tool from falling, and the anti-slip coating 17 can ensure that the workpiece will not slide during transportation and inspection.

[0030] The movable base 7 has two mounting slots 34, and each mounting slot 34 has a mounting block 35 inserted into it. The lower end of the mounting block 35 is fixedly connected to the conveyor belt 2. The two mounting blocks 35 on the same movable base 7 each have a telescopic groove 36 on opposite sides. A movable block 37 is slidably connected in the telescopic groove 36. The end of the movable block 37 away from the mounting slot 34 is fixedly connected to the inner wall of the telescopic groove 36 with a third spring 38. The end of the movable block 37 away from the spring 38 is fixedly connected to a limit block 39. Each mounting block 35 has a limit slot 40 at the corresponding position in the telescopic groove 36. The end of the limit block 39 away from the movable block 37 is inserted into the corresponding limit slot 40 to limit the movement and ensure that the movable base 7 is firmly fixed on the conveyor belt 2. It should be noted that the upper end of each mounting block 35 is beveled, which makes it convenient to directly align the mounting socket 34 on the movable base 7 with the mounting block 35 and insert it directly during installation. This allows the limiting block 39 to first retract into the telescopic groove 36 and then pop out to directly insert into the corresponding limiting slot 40, thus completing the installation.

[0031] The front end of the movable base 7 and the corresponding positions of each telescopic groove 36 are provided with a movable opening 41 communicating with the telescopic groove 36. A movable rod 42 is slidably connected in each movable opening 41. The movable rod 42 is fixedly connected to the front end of the corresponding movable block 37. A vertically set pull rod 43 is fixedly connected to the end of each movable rod 42 away from the movable block 37. By setting the pull rod 43, when it is necessary to disassemble the transport carrier 6, the two pull rods 43 can be pulled inward, which can drive the movable block 37 to move, so that the limiting plug 39 is put into the telescopic groove 36, releasing the limitation between it and the installation plug 35. Then the transport carrier 6 can be directly removed from the conveyor belt 2. The operation is simple and convenient and suitable for assembly line work.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
