Description

Technical Field

[0001] This utility model relates to the technical field of disc-shaped workpiece inspection equipment, and in particular to an automatic barcode scanning and rating device for disc-shaped workpieces after they are removed from the production line. Background Technology

[0002] In industries such as machinery manufacturing and automotive parts, when disc-shaped workpieces (such as gears, flanges, and brake discs) are completed and off the production line, their identification information (linked to production batch, process parameters, etc.) needs to be scanned and their quality rating checked to achieve production traceability, quality control, and subsequent sorting and transfer. With the continuous rise in manufacturing and labor costs for manufacturing enterprises, and the increasing demands of users for product quality and efficiency, traditional manufacturing enterprises urgently need to reduce production costs, decrease labor input, and improve product quality. The transformation of traditional factories into smart factories has become an inevitable trend. In traditional production workshops, the marking, scanning, and grading of disc-shaped workpieces after they come off the production line are generally done in an open working environment, relying heavily on manual scanning. This method has many drawbacks: on the one hand, manual scanning is inefficient and labor-intensive, making it difficult to meet the needs of high-efficiency production; on the other hand, the complex lighting conditions in an open environment can easily interfere with the scanning process, leading to inaccurate QR code grading and affecting the quality of product information collection. Furthermore, manual operation is not conducive to the digital management of the production process and the automatic collection, statistics, and feedback of information, failing to meet the requirements of digital and intelligent production workshops. Therefore, we propose an automatic scanning and grading device for disc-shaped workpieces after they come off the production line. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic barcode scanning and grading device for the unloading of disc-shaped workpieces.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic barcode scanning and grading device for unloading disc-shaped workpieces includes a worktable. A positioning sleeve is mounted on the worktable via a rotating mechanism, which drives the positioning sleeve to rotate. A door is mounted on the worktable via a first cylinder. A guide mechanism for guiding the door is mounted on the side of the worktable. A barcode scanner is mounted on the worktable via a moving mechanism, which drives the barcode scanner to move. A shaft mounting base is mounted on the worktable. A sensor mounting block is mounted on the shaft mounting base via a fixed shaft. A detection sensor is mounted on the sensor mounting block. A control unit is installed inside the worktable. Feet are installed at the bottom of the worktable.

[0005] Preferably, the rotating mechanism includes a motor, a reducer, a coupling, and a bearing housing. The motor is installed inside the worktable, the reducer is connected to the output shaft of the motor, the output end of the reducer is mounted on a bearing housing via a coupling, and the positioning sleeve is installed on the top of the bearing housing.

[0006] Preferably, the guiding mechanism includes a profile frame, a linear guide, a slider, and a buffer.

[0009] Preferably, the control unit includes a manifold, a solenoid valve, and a connector, and the control unit is electrically connected to internal components.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the motor is started, and the motor provides rotational power.

[0011] 2.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1 , Figure 2 An automatic barcode scanning and grading device for disc-shaped workpieces after production line assembly includes a worktable 1. A positioning sleeve 3 is mounted on the worktable 1 via a rotating mechanism 2. The positioning sleeve 3 is adapted to the center of the disc-shaped workpiece, ensuring stable rotation of the workpiece with the positioning sleeve 3. The positioning sleeve 3 is replaceable. The rotating mechanism 2 drives the positioning sleeve 3 to rotate, facilitating scanning of different angle areas of the workpiece and preventing missed scans. A door 5 is mounted on the worktable 1 via a first cylinder 4, providing power for opening and closing the door 5. A guide mechanism 6 is installed on the side of the worktable 1 to guide the door 5. The guide mechanism 6 ensures the movement accuracy of the door 5, providing buffering when the door 5 opens and closes, preventing damage from hard impacts, and creating a relatively enclosed scanning space to reduce external light interference and improve scanning accuracy. The worktable 1 is moved... Mechanism 7 is equipped with a barcode scanner 8. The moving mechanism 7 is used to move the barcode scanner 8. The moving mechanism 7 can move the barcode scanner 8 closer to or away from the workpiece, thereby realizing the adjustment of the scanning distance, which facilitates automatic scanning and grading of the workpiece. A shaft mounting seat 9 is installed on the worktable 1. A sensor mounting block 11 is installed on the shaft mounting seat 9 through a fixed shaft 10. A detection sensor 12 is installed on the sensor mounting block 11. The detection sensor 12 is used to detect whether the disc-shaped workpiece is in place and provide a trigger signal for the automatic operation of the equipment. A control unit 13 is installed inside the worktable 1. The control unit 13 includes a manifold, solenoid valve and connector, etc. The control unit 13 is electrically connected to the internal components. The bottom of the worktable 1 is equipped with feet 14. The feet 14 have height and level adjustment functions to adapt to different ground environments, ensure the overall stability of the equipment, and avoid the workpiece positioning and scanning accuracy being affected by the tilt of the equipment.

[0016] Reference Figure 3 The rotating mechanism 2 includes a motor 21, a reducer 22, a coupling 23, and a bearing housing 24. The motor 21 is installed inside the worktable 1. The output shaft of the motor 21 is connected to the reducer 22. The output end of the reducer 22 is connected to the bearing housing 24 through the coupling 23. The positioning sleeve 3 is installed on the top of the bearing housing 24. When the motor 21 is started, the motor 21 provides rotational power. After the speed is reduced and the torque is increased by the reducer 22, the torque is transmitted to the bearing housing 24 through the coupling 23, causing the bearing housing 24 to drive the positioning sleeve 3 to rotate. This allows the positioning sleeve 3 to drive the workpiece to rotate, which facilitates scanning of different angle areas of the workpiece and avoids missed scans.

[0017] Reference Figure 4 The guide mechanism 6 includes a profile frame 61, a linear guide 62, a slider 63, and a buffer 64. The profile frame 61 is fixed to the side of the workbench 1. The linear guide 62 is installed inside the profile frame 61, and the slider 63 is slidably installed on the linear guide 62. Buffers 64 are installed at the bottom of the profile frame 61. There are two buffers 64, located at both ends of the movement trajectory of the door body 5. The slider 63 is fixedly connected to the door body 5. When the first cylinder 4 is activated, the piston rod of the first cylinder 4 drives the door body 5 to move up and down, causing the door body 5 to move the slider 63 along the linear guide 62 on the profile frame 61. The buffers 64 buffer when the door body 5 moves to both ends to avoid impact damage, thereby enabling the door body 5 to open and close. After the door is closed, a stable light environment can be created to improve the scanning accuracy.

[0018] Reference Figure 2 The moving mechanism 7 includes a second cylinder 71, a cable chain 72, and a support 73. The second cylinder 71 is mounted on the support 73, and the cable chain 72 is mounted on the side of the second cylinder 71. The support 73 is mounted on the end of the piston rod of the second cylinder 71. The barcode scanner 8 is mounted on the support 73. When the second cylinder 71 is activated, the piston rod of the second cylinder 71 drives the support 73 to move, so that the support 73 drives the barcode scanner 8 closer to or away from the workpiece. At the same time, the cable chain 72 is used to store the cable of the barcode scanner 8, thereby realizing the adjustment of the scanning distance, which facilitates automatic scanning and grading of the workpiece.

[0019] Working principle: The disc-shaped workpiece is placed on the positioning sleeve 3 by a person or a robot. The detection sensor 12 recognizes the workpiece positioning signal and transmits it to the control unit 13.

[0020] Control unit 13 starts first cylinder 4. The piston rod of first cylinder 4 drives door 5 to move up and down, so that door 5 drives slider 63 to slide along the linear guide 62 on profile frame 61. Buffer 64 buffers when door 5 moves to both ends to avoid impact damage, so that door 5 can be closed to form a relatively closed space. After the door is closed, a stable light environment can be created to improve the accuracy of barcode scanning.

[0021] During scanning, the control unit 13 activates the second cylinder 71. The piston rod of the second cylinder 71 drives the support 73 to move, causing the support 73 to move the barcode scanner 8 closer to or away from the workpiece. At the same time, the cable chain 72 is used to store the cable of the barcode scanner 8, thereby enabling the adjustment of the scanning distance and facilitating automatic barcode scanning and grading of the workpiece.

[0022] When the scanning area on the workpiece is in a different position, the motor 21 is started. The motor 21 provides rotational power. After the speed is reduced and the torque is increased by the reducer 22, the torque is transmitted to the bearing seat 24 through the coupling 23, so that the bearing seat 24 drives the positioning sleeve 3 to rotate. In this way, the positioning sleeve 3 can drive the workpiece to rotate, so that the barcode scanner 8 can perform all-round barcode scanning and identification and quality rating on the rotating workpiece. The data is transmitted to the control unit 13 or the associated system in real time to avoid missed scanning.

[0023] After the barcode scanning and rating are completed, the control unit 13 controls the motor 21 to stop, the second cylinder 71 pulls the barcode scanner 8 to reset, the first cylinder 4 pulls the door 5 to open, and the workpiece is taken away manually or by a robotic arm, completing one work cycle.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
