DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1As shown, the present invention is an automated device, which realizes efficient code scanning of stepped shafts and round shaft workpieces 4.4 through precise mechanical design and intelligent control system. The present invention is mainly composed of key components such as a base 1, a rotating component 4, a power device, a linear guide 1.1, a rodless cylinder, a scanner 2 and a sensor 3, which work together to ensure the accuracy and reliability of the code scanning process. The base 1 is the foundation of the entire rotating code scanning mechanism, which adopts a solid metal structure to ensure the stability and durability of the entire mechanism during operation. The rotating component 4 and the scanner 2 are installed above the base 1, and a mounting frame 2.3 is installed at one end of the upper surface of the base 1. The scanner 2 is installed on the second rodless cylinder 2.1, which is fixed to the top of the mounting frame 2.3 at one end of the base 1. The left and right sliding of the second rodless cylinder 2.1 enables the scanner 2 to cover the scanning range of the entire rotating component 4, thereby improving the flexibility and coverage of code scanning. Two parallel linear guides 1.1 are provided on the upper surface of the base 1. The linear guides 1.1 are arranged along the width direction of the base 1 and are parallel to the direction of the rotating axis 4.2. The linear guides 1.1 are respectively located on two opposite sides of the upper surface of the base 1 and are symmetrically arranged along the central axis of the upper surface of the base 1. The symmetrical arrangement of the linear guides 1.1 helps to balance the load, reduce the offset, and improve the stability of the entire mechanism. The rotating assembly 4 is arranged on the linear guide 1.1 and moves back and forth under the drive of the first rodless cylinder. After the workpiece 4.4 is placed at one end of the base 1, the rotating assembly 4 together with the placed workpiece 4.4 is quickly and accurately moved to the bottom of the scanner 2 under the drive of the first rodless cylinder and the guidance of the linear guide 1.1, realizing an efficient code scanning process. The main body of the base 1 is composed of a protective shell, which not only provides physical protection for the equipment, but also contributes to the neatness and beauty of the equipment. A switch is provided on one side of the protective shell. The interior is provided with a control circuit and an electromagnetic valve assembly for controlling the air path. These components are the core of realizing the automatic control of the equipment. The control circuit receives the signal from the master control to control the motor 4.5.5, the scanner 2 and the electromagnetic valve in the control gas path below, and feeds back the detection signal of the detection switch and the scanner 2. The electromagnetic valve below is used to control the second rodless cylinder 2.1 on the scanner 2, thereby controlling the left and right translation of the scanner 2, and to control the first rodless cylinder below the motor 4.5.5, thereby controlling the forward and backward movement of the rotating assembly 4.

[0025] like Figure 1 and Figure 2 and Figure 3As shown, the rotating assembly 4 is composed of a first fixed plate 4.5, a second fixed plate 4.6 and several groups of rotating parts rotatably connected between the two plates. In this embodiment, two groups of rotating parts are used. The rotating assembly 4 is fixedly mounted on the transfer platform 4.9. The design of the transfer platform 4.9 fully considers the installation convenience and stability of the rotating assembly 4. The transfer platform 4.9 is provided with several mounting holes, and the layout and size of these mounting holes are carefully designed to facilitate the rapid installation and adjustment of the rotating assembly 4. Symmetrical mounting platforms are provided on both sides of the bottom, and each mounting platform is provided with two mounting holes, and the rotating assembly 4 is fixedly mounted on the transfer platform 4.9 by bolts. Such a design not only ensures the stability of the rotating assembly 4, but also facilitates maintenance and replacement. The width of the transfer platform 4.9 is the same as the width of the rotating assembly 4, and the length is slightly larger than the length of the rotating assembly 4. Two sliders 4.9.1 are provided on both sides of the transfer platform 4.9, and four sliders 4.9.1 are arranged at the four corners of the transfer platform 4.9. The sliders 4.9.1 are slidably connected to the linear guide 1.1. The direction of the linear guide 1.1 is parallel to the direction of the rotating shaft 4.2, and is used to guide the first rodless cylinder to drive the rotating assembly 4 to move forward and backward, so that the rotating assembly 4 can move smoothly to the bottom of the scanner 2, which provides great convenience for scanning codes. The transfer platform 4.9 is installed above the linear guide 1.1 and the first rodless cylinder. Under the drive of the first rodless cylinder and the guidance of the linear guide 1.1, the supporting rotating assembly 4 moves forward and backward, so that the rotating assembly 4 can move from one end of the base 1 to the other end, thereby realizing the automation of the scanning process. In actual application, the rotating assembly 4 is at one end of the base 1. After the robot places the workpiece 4.4 on the rotating assembly 4, the four sensors 3 will sense whether the workpiece 4.4 has been correctly placed in the rotating assembly 4. Once the sensor 3 confirms that the workpiece 4.4 has been placed in place, the first rodless cylinder will drive the transfer platform 4.9 to move forward and backward, and the supporting rotating assembly 4 and the workpiece 4.4 will move quickly and accurately to the bottom of the scanner 2, thereby achieving efficient code scanning.

[0026] The rotating assembly 4 is the core part of the present invention, which includes several groups of rotating parts. In this embodiment, two rotating assemblies 4 are provided, and each group of rotating parts is composed of two rotating shafts 4.2. The two ends of the rotating shaft 4.2 are rotatably fixed between the first fixed plate 4.5 and the second fixed plate 4.6. The rotating shaft 4.2 is also a stepped shaft, and the diameter of the two ends is smaller than the diameter of the middle part. Such a design provides convenience for the installation of the rotating wheel 4.3. The fixed sleeves at both ends of each rotating shaft 4.2 are provided with rotating wheels 4.3. The length of the smaller diameter section at both ends of the rotating shaft 4.2 is equal to the width of the rotating wheel 4.3, and the diameter of the rotating wheel 4.3 is larger than the diameter of the rotating shaft 4.2, so as to realize the hollow design. This design not only allows the stepped shaft to scan the code smoothly, but also can adapt to shaft workpieces 4.4 of different diameters. The diameter of the rotating wheel 4.3 can be designed specifically according to the different diameters at both ends of the shaft workpiece 4.4, which expands the application range of the scanning, thereby improving the versatility and practicality of the entire rotating code scanning mechanism. The design of the rotating assembly 4 takes full account of the flexibility and efficiency of the production line, and can be compatible with two workpieces 4.4 of different sizes for rotation at the same time, which greatly improves the convenience in the production process. In a traditional rotary scanning device, if two workpieces 4.4 with specific spacing requirements need to be processed, and the two workpieces 4.4 also need to rotate synchronously, two independent rotary machines or additional variable pitch mechanisms are usually required to adjust the distance between the workpieces 4.4. Such a configuration not only increases the cost of the equipment, but also takes up more space, reducing the compactness and efficiency of the production line. However, the rotating assembly 4 provided in this embodiment can meet the needs of a rotating assembly 4 to process two workpieces 4.4 at the same time without the need for additional equipment or a complex adjustment process. This design allows the two workpieces 4.4 to maintain an appropriate spacing on the rotating assembly 4 and to rotate synchronously, ensuring the consistency and accuracy of the scanning process. Such a solution not only simplifies the equipment configuration and reduces space occupancy, but also improves the flexibility and production efficiency of the production line. The two sets of rotating parts are symmetrically arranged along the central axis of the base 1, all rotating shafts 4.2 are located on the same horizontal plane, and all rotating wheels 4.3 are located on the same plane to ensure the smooth rotation of the workpiece 4.4. The material of the rotating wheel 4.3 is preferably a polyurethane wheel, which has high wear resistance: its wear resistance is several to dozens of times that of ordinary rubber materials, ensuring that the rotating wheel 4.3 provides sufficient friction when driving the workpiece 4.4 to rotate, preventing the workpiece 4.4 from sliding or falling off during rotation, thereby ensuring the continuity and stability of the scanning process; high load-bearing capacity: the polyurethane wheel has high mechanical strength and can withstand large weights and loads, ensuring the reliability and durability of the rotating component 4 when facing heavy loads; low rolling resistance: the polyurethane wheel has low rolling resistance, which helps to improve energy efficiency and reduce energy loss; excellent elasticity and shock absorption performance: the polyurethane wheel has high elasticity of rubber, can effectively absorb shock and vibration, provide the workpiece 4.4 with smoother rotation, and reduce damage to the workpiece 4.4.

[0027] like Figure 4 and Figure 5As shown, the transmission wheels of the present invention are respectively arranged on the outside of the first fixed plate 4.5 and the second fixed plate 4.6. The power device, in this embodiment, is preferably a motor 4.5.5, which serves as the power source of the rotating code scanning mechanism and is responsible for driving the entire rotation process. The motor 4.5.5 is arranged between the first fixed plate 4.5 and the second fixed plate 4.6, and between the two groups of rotating parts. It directly drives the first driving wheel 4.5.1 and transmits power to all driven wheels through the synchronous belt 4.7. This design ensures the efficient transmission of power and the synchronization of the rotation action, and improves the response speed and stability of the mechanism. The two rotating shafts 4.2 located on the inner side of the rotating part are respectively fixedly connected to the two first driven wheels 4.5.2 on the outer side of the first fixed plate 4.5. The two first driven wheels 4.5.2 are located on the same horizontal plane and are symmetrically arranged along the central axis of the base 1. The two first driven wheels 4.5.2 are connected by a synchronous belt 4.7. A guide wheel a4.5.4 is arranged at the middle upper end of the synchronous belt 4.7 between the two first driven wheels 4.5.2. The guide wheel a4.5.4 fits with the synchronous belt 4.7 to provide guidance for the synchronous belt 4.7, prevent the synchronous belt 4.7 from being misaligned, and ensure the accuracy and reliability of power transmission. The guide wheel a4.5.4 and the two first driven wheels 4.5.2 are located on the same plane, the first driving wheel 4.5.1 is located below the first driven wheel 4.5.2 and on the symmetry axis of the two first driven wheels 4.5.2, the diameter of the first driving wheel 4.5.1 is smaller than the diameter of the first driven wheel 4.5.2, the two first driving wheels 4.5.1 are connected to the first driven wheels 4.5.2 through the same synchronous belt 4.7, the first driving wheel 4.5.1 is connected to the motor 4.5.5, and the active rotation drives the first driven wheel 4.5.2 to rotate passively through the synchronous belt 4.7. In order to further improve the transmission efficiency, a clamping wheel 4.5.3 is respectively arranged on the synchronous belt 4.7 between the first driving wheel 4.5.1 and the two first driven wheels 4.5.2. These clamping wheels 4.5.3 clamp the synchronous belt 4.7 toward the middle, increasing the contact area between the synchronous belt 4.7 and the first driving wheel 4.5.1 and the first driven wheel 4.5.2, thereby improving the transmission efficiency. The two rotating shafts 4.2 located on the inner side of the rotating member are fixedly connected to the second driving wheel 4.6.1 on the outer side of the second fixed plate 4.6, and the rotating shaft 4.2 located on the outer side is fixedly connected to the second driven wheel 4.6.2 on the outer side of the second fixed plate 4.6. The second driving wheel 4.6.1 and the second driven wheel 4.6.2 are located on the same horizontal plane, and the second driving wheel 4.6.1 and the second driven wheel 4.6.2 are connected by a synchronous belt 4.7. A guide wheel is provided below the second driving wheel 4.6.1 and the second driven wheel 4.6.2. The guide wheel b4.6.3 is located on the symmetric axis of the second driving wheel 4.6.1 and the second driven wheel 4.6.2, and is connected to the second driving wheel 4.6.1 and the second driven wheel 4.6.2 by the same synchronous belt 4.7, providing guidance for the synchronous belt 4.7 to prevent the synchronous belt 4.7 from being misplaced when sent.When the power device is started, the power device drives the first driving wheel 4.5.1 to rotate, and the rotation of the first driving wheel 4.5.1 drives the two second driven wheels 4.6.2 to rotate synchronously, and the rotation of the two second driven wheels 4.6.2 drives the two rotating shafts 4.2 located on the inner side to rotate synchronously, and the rotation of the rotating shaft 4.2 located on the inner side drives the second driving wheel 4.6.1 to rotate, and the second driving wheel 4.6.1 drives the second driven wheel 4.6.2 to rotate through the synchronous belt 4.7, and the second driven wheel 4.6.2 drives the two rotating shafts 4.2 located on the outer side to rotate synchronously, ensuring the synchronous rotation of the two rotating shafts 4.2 and the two groups of rotating parts in the rotating part, further improving the consistency and accuracy of code scanning. The first driving wheel 4.5.1, the first driven wheel 4.5.2, the second driving wheel 4.6.1, and the second driven wheel 4.6.2 are all provided with a plurality of protrusions on the circumference, and the length of the protrusions is the same as the thickness of the transmission wheel, so as to increase the friction with the synchronous belt 4.7 and improve the efficiency and stability of the transmission.

[0028] like Figure 3 As shown, a protective cover 4.8 is provided on the outside of the first fixed plate 4.5 and the second fixed plate 4.6 to protect the transmission assembly from damage or interference by external factors during operation. The design of the protective cover 4.8 not only improves the safety of the equipment, but also helps to reduce the entry of dust and debris into the interior of the equipment, thereby reducing maintenance costs and failure rates. A partition is provided between the bottom ends of the two protective covers 4.8. There are two partitions in total, which are symmetrically arranged. The partition is located below the rotating part and is used to protect the motor 4.5.5 and other components inside the rotating assembly 4. A baffle 4.1 is provided above the two ends of each rotating part at the top of the first fixed plate 4.5 and the second fixed plate 4.6. The symmetry axis of the baffle 4.1 coincides with the symmetry axis of the rotating part. The height and position of the baffle 4.1 can be adjusted according to the size of the workpiece 4.4 to ensure that the workpiece 4.4 always remains in the correct position during the rotation process. In this embodiment, four baffles 4.1 are provided, which are symmetrical around the center of the rotating assembly 4 to form a stable protective structure. The baffles 4.1 can prevent the workpiece 4.4 from deflecting or falling off during the rotation process, ensuring that the workpiece 4.4 always remains in the correct position for scanning. The design of the baffles 4.1 improves the accuracy and reliability of scanning.

[0029] like Figure 1As shown, the sensor 3 is an important component for realizing automatic control, and it is used to detect whether a workpiece 4.4 is placed on the rotating assembly 4. Four sensors 3 are arranged on both sides of the upper surface of the base 1. The four sensors 3 are grouped in pairs and are respectively located on both sides of the linear guide rail 1.1. The sensors 3 are installed on the support rod 3.1 and are distributed symmetrically with respect to the center. One of the sensors 3 in a group is located at one end of the base 1. The distance between the two sensors 3 in a group is greater than the width of the rotating assembly 4, taking into account the different placement positions of the transfer platform 4.9, thereby ensuring that the sensor 3 can always accurately detect the existence and position of the workpiece 4.4.

[0030] like Figure 6 As shown, above the rotating assembly 4, the present invention designs a scanner 2, which is mounted on the second rodless cylinder 2.1, allowing the scanner 2 to move in the direction of the first rodless cylinder, that is, to move left and right. The second rodless cylinder 2.1 is fixed to the top of a mounting bracket 2.3 located at one end of the linear guide rail 1.1, and the height of the mounting bracket 2.3 is greater than the height of the rotating assembly 4, so that the scanner 2 can adjust the left and right position without interfering with the normal operation of the rotating assembly 4. A hose connector 2.2 is provided at one end of the mounting frame 2.3 and one side of the scanner 2 for routing, such as the power line and the signal line of the scanner 2, so as to protect the circuit and reduce the interference of the line to the mechanical movement. The direction of the second rodless cylinder 2.1 is perpendicular to the direction of the rotating axis 4.2. The second rodless cylinder 2.1 drives the scanner 2 to move in the direction perpendicular to the rotating axis 4.2, that is, to move left and right. In this way, the position of the scanner 2 can be flexibly adjusted, so that the scanner 2 can be flexibly adjusted to scan the workpiece 4.4 at different positions, further increasing the adjustment range of the scanner 2. No matter where the workpiece 4.4 is located on the rotating component 4, the scanner 2 can easily align with and scan the workpiece 4.4, thereby improving the flexibility and adaptability of the scanning and realizing efficient and accurate code scanning operations.

[0031] The working process of this embodiment.

[0032] 1.4.4 Placement of workpiece.

[0033] The transfer platform 4.9 is located at one end of the base 1 away from the scanner 2. After the robot places the workpiece 4.4 to be scanned at the specified position on the rotating axis 4.2 of the rotating component 4, the sensors 3 located on the upper surface of the base 1 start working to accurately detect whether the workpiece 4.4 has been placed on the rotating component 4. Once the sensors 3 detect the workpiece 4.4, they will immediately send a signal to the main control to inform that the workpiece 4.4 is in place.

[0034] 2. Transfer platform 4.9 moves.

[0035] After the master control receives the signal, it sends a signal to the control circuit, the control circuit sends a signal to the solenoid valve assembly, the solenoid valve assembly controls the air circuit, the first rodless cylinder starts, and under the guidance of the linear guide rail 1.1, the transfer platform 4.9 carrying the rotating assembly 4 is moved back and forth to the bottom of the scanner 2.

[0036] 3. Start the power unit.

[0037] After the transfer platform 4.9 moves to the bottom of the scanner 2, the control circuit sends a signal to start the power device, namely the motor 4.5.5. The motor 4.5.5, as the power source of the rotating code scanning mechanism, starts to run and drives the first driving wheel 4.5.1.

[0038] 4. The rotating component 4 rotates.

[0039] As the power is transmitted, the rotating assembly 4 starts to rotate. The rotation of the first driving wheel 4.5.1 drives the two second driven wheels 4.6.2 to rotate synchronously. The rotation of the two second driven wheels 4.6.2 drives the two rotating shafts 4.2 located on the inner side to rotate synchronously. The rotation of the rotating shaft 4.2 located on the inner side drives the second driving wheel 4.6.1 to rotate. The second driving wheel 4.6.1 drives the second driven wheel 4.6.2 to rotate through the synchronous belt 4.7. The second driven wheel 4.6.2 drives the two rotating shafts 4.2 located on the outer side to rotate synchronously. The rotating shaft 4.2 drives the rotating wheel 4.3 to rotate. The rotating wheel 4.3 drives the workpiece 4.4 thereon to rotate. This design ensures the efficient transmission of power and the synchronization of the rotating action, and improves the response speed and stability of the mechanism. Each set of rotating parts consists of two rotating shafts 4.2, and the fixed sleeves at both ends of each rotating shaft 4.2 are provided with rotating wheels 4.3. These rotating wheels 4.3 are made of polyurethane material, which has high wear resistance, high load-bearing capacity and low rolling resistance, ensuring the stability and reliability during the rotation process. The diameter of the rotating wheel 4.3 is slightly larger than the diameter of the rotating shaft 4.2, realizing a hollow design so that the stepped shaft workpiece 4.4 can also be scanned smoothly.

[0040] 5. Scan.

[0041] While the rotating assembly 4 rotates, the scanner 2 starts to work. The scanner 2 is mounted on the second rodless cylinder 2.1 and can move left and right along a direction perpendicular to the rotating axis 4.2. The scanner 2 can flexibly adjust its position to cover different areas on the rotating assembly 4.

[0042] 6. Processing and feedback.

[0043] Once Scanner 2 has successfully scanned, it sends the data to the control system for processing. The control system decodes and verifies the data.

[0044] 7. Finish the work.

[0045] When all workpieces 4.4 have been scanned, the control circuit will send a signal to stop the circuit and gas circuit. At this time, the rotating assembly 4 stops rotating, the scanner 2 and the rotating assembly 4 return to the initial position, and the entire rotating scanning mechanism enters a standby state, waiting for the placement of the next batch of workpieces 4.4.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
