[0033] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0034] In the description of the present application, it should be understood that the terms "up", "down", "front", "back", "left", "right", "vertical", "horizontal", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In some complex workpiece processing, different workpieces will be involved in the same process, and workpieces of different sizes will often enter the same processing section. For example, in the processing of mechanical parts, beams or longitudinal beams of different lengths will enter the same processing section for machining or heat treatment. However, in the existing code reading method, the installation position of the code reader is fixed and cannot be adjusted, which makes the code reader have a blind spot for reading codes and cannot take into account the code reading needs of workpieces of different sizes.

[0037] In this regard, the present embodiment provides a code reading device, in which a code reader is arranged on a movable frame, and the movable frame slides with a guide rail on a base frame through a movable member, so that the code reader moves with the movable frame under the power of a power member, and the moving direction of the movable frame on the guide rail intersects with the conveying direction of the workpiece, so that the code reader can be moved to different positions, thereby increasing the code reading area of ​​the code reader, reducing the code reading blind area of ​​the code reader, and enabling the code reader to read the code of workpieces of different sizes, thereby improving the code reading flexibility of the code reader.

[0038] The code reading device is introduced below in conjunction with the accompanying drawings. Those skilled in the art should understand that the following implementations are only illustrative and not exhaustive. Based on these implementations, those skilled in the art may replace, splice or combine certain features or examples, which should still be regarded as the disclosed content of this application.

[0039] like Figure 1 As shown, Figure 1 It is a schematic diagram of the overall structure of a code reading device provided in an embodiment of the present application, wherein the code reading device includes: a base frame 10, a code reader 20, a movable frame 30, and a power member 40.

[0040] The base frame 10 is the foundation of the code reading device and is used to install other components and provide support and activity space for other components. The base frame 10 is provided with a guide rail 11, and the style, quantity, and extension direction of the guide rail 11 can be variously set according to specific needs, and are not limited here.

[0041] The movable frame 30 is a frame structure matched with the guide rail 11 and is used to install the code reader 20. The movable frame 30 is provided with a moving member 31 matched with the guide rail 11, and the style and number of the moving member 31 match the guide rail 11, so that the movable frame 30 moves on the guide rail 11 through the moving member 31.

[0042] There are many ways to set the style of the moving member 31. For example, if the guide rail 11 is set to a protruding structure, the moving member 31 can be set to a slider or roller that engages with the protruding structure; if the guide rail 11 is set to a chute, the moving member 31 can be set to a slider or roller embedded in the chute. There are also many ways to set the number of moving members 31. For example, the number of moving members 31 can be consistent with the number of guide rails 11 so that the moving members 31 and the guide rails 11 match one by one, and the number of moving members 31 can also be more than the number of guide rails 11 so that multiple moving members 31 can match the same guide rail 11. Exemplarily, if the guide rail 11 is set with 2 parallel guide rails 11, the number of moving members 31 can also be set to 2, or 4, 5, 6, etc., which are not limited here.

[0043] The movable frame 30 is connected to the power member 40 and moves on the guide rail 11 under the power of the power member 40. The power member 40 is a structure that provides the power member 40 with moving power, which can be a motor, a pump, a magnetic device, etc., which is not limited here. When the movable member 31 is set as a slider, the movable frame 30 slides on the guide rail 11 through the slider under the power of the power member 40.

[0044] The code reader 20 is a mechanism for reading the workpiece code. It is installed on the movable frame 30, and the code reader 20 is separated from the guide rail 11 by a preset height difference. The moving direction of the movable frame 30 on the guide rail 11 intersects with the conveying direction of the workpiece, so that the code reader 20 can move with the movable frame 30 to the position for reading the workpiece code.

[0045] The preset height difference between the code reader 20 and the guide rail 11 is pre-set according to the height of the workpiece code, which can ensure that the code reader 20 is located in a good code reading position, so that there is a sufficient code reading area during the workpiece conveying process, so as to accurately read the workpiece code. In addition, the extension direction of the guide rail 11 intersects with the conveying direction of the workpiece, so that the moving direction of the movable frame 30 on the guide rail 11 intersects with the conveying direction of the workpiece, and the distance between the code reader 20 and the workpiece can be adjusted by moving the movable frame 30 on the guide rail 11, so that the code reader 20 can be moved to the position of reading the workpiece code, thereby reducing the code reading blind area of ​​the code reader 20 by adjusting the distance between the code reader 20 and the workpiece.

[0046] In order to further reduce the code reading blind area of ​​the code reader 20, the code reader 20 can be installed on the mobile frame in a height-adjustable installation form, so that the position of the code reader 20 can be changed by adjusting the height difference between the code reader 20 and the guide rail 11 bracket, thereby enriching the code reading area of ​​the code reader 20 and reducing the code reading blind area of ​​the code reader 20.

[0047] There are many implementation methods for installing the code reader 20 on the mobile frame in a height-adjustable installation form. One feasible implementation method is as follows: Figure 2 As shown, Figure 2 1 is a partial schematic diagram of a code reading device provided in an embodiment of the present application. A first support column 32 is provided on the movable frame 30, and the first support column 32 is axially fixed to the movable frame 30 along the height direction. The code reader 20 is movably mounted on the first support column 32; when the code reader 20 moves axially along the first support column 32, the height difference between the code reader 20 and the guide rail 11 changes accordingly.

[0048] In this embodiment, the first support 32 stands on the movable frame 30, and the code reader 20 can move along the circumference of the first support 32, so as to adjust the height difference between the code reader 20 and the guide rail 11. Moreover, the code reader 20 can be fixed at the adjusted height position by clamping, bolting or screwing, etc., which is not limited here.

[0049] In addition, the code reader 20 can be installed on the mobile frame in a height-adjustable installation form, and can also be set to other structural forms. For example, the code reader 20 can be installed on the movable frame 30 through a structure that can be telescopic in the height direction, so that the code reader 20 can be telescopic in the height direction, thereby achieving the adjustment of the height difference. In addition, the code reader 20 can be installed in a height-adjustable manner in other feasible implementations, which are not limited here.

[0050] In addition to installing the code reader 20 on the mobile frame in a height-adjustable installation form, the code reader 20 can be further set to a transversely adjustable installation form, that is, if the code reader 20 moves along the X-axis direction with the direction in which the movable frame 30 moves on the guide rail 11, and the code reader 20 is installed on the mobile frame in a height-adjustable installation form so that the code reader 20 moves along the Z-axis direction, then setting the code reader 20 in a transversely adjustable installation form can make the code reader 20 move along the Y-axis direction, so that the code reader 20 can reach more positions, thereby further reducing the code reading blind area of ​​the code reader 20. Among them, the X-axis, Y-axis and Z-axis refer to three coordinate axes in a three-dimensional space, and these three coordinate axes are perpendicular to each other.

[0051] There are many feasible implementations for setting the code reader 20 in a laterally adjustable installation form. One feasible implementation is as follows: Figure 2 As shown, a second pillar 33 is provided on the movable frame 30, and the second pillar 33 is movably mounted on the first pillar 32, and the code reader 20 is movably mounted on the second pillar 33; the axis of the second pillar 33 is perpendicular to the axis of the first pillar 32, and the axis of the second pillar 33 is perpendicular to the extension direction of the guide rail 11; when the second pillar 33 moves axially along the first pillar 32, the height difference between the code reader 20 and the guide rail 11 changes accordingly; when the code reader 20 moves axially along the first pillar 32, the code reader 20 approaches or moves away from the guide rail 11 along the axial direction of the first pillar 32.

[0052] In this embodiment, the code reader 20 can move with the movable frame 30 to achieve longitudinal adjustment (adjustment in the X-axis direction), can also move axially along the first pillar 32 to achieve height adjustment (adjustment in the Z-axis direction), and can also move axially along the second pillar 33 to achieve lateral adjustment (adjustment in the Y-axis direction), so that the code reader 20 has enough free position adjustment space, allowing the code reader 20 to reach more positions, greatly reducing the code reading blind area of ​​the code reader 20.

[0053] In this embodiment, the power member 40 and the movable frame 30 can be directly connected or connected through the transmission assembly 50. There are many implementation methods for connecting the power member 40 and the movable frame 30 through the transmission assembly 50. One feasible implementation method can be as follows: Figure 1 As shown, the power member 40 is fixed on the base frame 10 and located at the first end of the guide rail 11; the power member 40 is connected to the movable frame 30 through the transmission assembly 50 to drive the movable frame 30 to move back and forth between the first end of the guide rail 11 and the second end of the guide rail 11.

[0054] In this embodiment, the power member 40 is arranged at the first end of the guide rail 11, and the transmission assembly 50 applies force to the movable frame 30, pulling the movable frame 30 toward the power member 40 or pushing the power member 40 to the second end, thereby ensuring the spatial layout of the overall mechanism and making the force transmission direction single, thereby avoiding power loss.

[0055] There are many implementation methods of the transmission assembly 50. One feasible implementation method is as follows: Figure 2 and Figure 3 As shown, Figure 3 : is a cross-sectional view of a code reading device provided by an embodiment of the present application. The transmission assembly 50 includes a driving wheel 51, a belt 52 and a driven wheel 53; the driving wheel 51 is connected to the power member 40 and rotates under the power of the power member 40, and the driven wheel 53 is rotatably arranged on the base frame 10 and located at the second end of the guide rail 11. The driving wheel 51 and the driven wheel 53 are connected by a belt 52 so that the driving wheel 51, the belt 52 and the driven wheel 53 rotate synchronously; the belt 52 is fixedly connected to the movable frame 30, and when the belt 52 rotates, it pulls the movable frame 30 to move on the guide rail 11.

[0056] In this embodiment, the belt 52 is sleeved between the driving wheel 51 and the driven wheel 53, the driving wheel 51 is connected to the power member 40, and the driven wheel 53 is in a rotatable free state. When the power member 40 is working, the power member 40 drives the driving wheel 51 to rotate, and the belt 52 will rotate accordingly. The belt 52 is also fixedly connected to the movable frame 30. During the rotation of the belt 52, the movable frame 30 is driven to move on the guide rail 11, so that the code reader 20 installed on the movable frame 30 moves accordingly.

[0057] In addition, in order to enhance the power transmission effect between the active member and the active wheel 51, the active wheel 51 can be a gear, and / or the driven wheel 53 can be a gear. Due to the size of the gap between the teeth, when the belt 52 is sleeved on the active wheel 51 and the driven wheel 53, the belt 52 can be installed more firmly, and the power transmission effect is also stronger.

[0058] There are many ways to fix the belt 52 and the movable frame 30. One feasible implementation is that a clamping structure 34 is provided on the movable frame 30, and the clamping structure 34 clamps the belt 52 so that the belt 52 is fixedly connected to the movable frame 30. Of course, the belt 52 and the belt can also be fixedly connected by bonding, clamping, etc., which is not limited here.

[0059] In addition, the code reading device may be provided with other settings to make the adjustment process more humane when adjusting the code reading position of the code reader 20 .

[0060] Exemplarily, in one embodiment, a first end of the guide rail 11 and a second end of the guide rail 11 are respectively provided with a stopper 12 for preventing the movable frame 30 from separating from the guide rail 11, thereby preventing the movable frame 30 from separating from the guide rail 11 during movement.

[0061] In another feasible implementation, a positioning scale is provided on the movable frame 30 to locate the position of the movable frame 30 on the guide rail 11. The positioning scale can be used to indicate the initial position of the movable frame 30, and can also be used to indicate the distance between the movable frame 30 and the two ends of the guide rail 11, so as to guide the operator to debug or detect the installation position of the movable frame 30.

[0062] In the code reading device provided in this embodiment, the code reader 20 is arranged on the movable frame 30, and the movable frame 30 is slidably matched with the guide rail 11 on the base frame 10 through the movable member 31, so that the code reader 20 moves with the movable frame 30 under the power of the power member 40, and the moving direction of the movable frame 30 on the guide rail 11 intersects with the conveying direction of the workpiece, so that the code reader 20 can be moved to different positions, thereby increasing the code reading area of ​​the code reader 20, reducing the code reading blind area of ​​the code reader 20, so that the code reader 20 can read the code of workpieces of different sizes, and improving the code reading flexibility of the code reader 20.

[0063] It should be noted that, although several structures, components or units for realizing related functions are mentioned in the above detailed description, such division is not mandatory. In fact, according to the specific implementation of the present application, the features and functions of two or more structures, components or units described above can be concretized in one structure, component or unit. Conversely, the features and functions of one structure, component or unit described above can be further divided into multiple components, structures or units to be concretized.

[0064] In addition, although the components and the installation methods of the components or devices in the present application are described in a specific order in the drawings, this does not require or imply that the components or devices must be designed according to the specific components or the installation methods of the components, or that all the components shown must be included to achieve the desired results. Additionally or alternatively, some components can be omitted, multiple components can be combined into one component to achieve corresponding functions, and / or one component can be decomposed into multiple components to achieve corresponding functions, etc.
