[0027] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention.

[0028] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0029] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0030] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0031] The present invention proposes an embodiment of an OCR recognition device, specifically, Figures 1 to 5 As shown, it includes: a base plate 1, a support rod 2 is provided on one side of the upper end of the base plate 1, a mounting top plate 11 is provided on the top end face of the support rod 2, an adjusting rod 3 is provided on the outer end of one side of the upper end of the support rod 2, a concave clamping groove 6 is provided on one end face of the adjusting rod 3, and a detection lens 5 is provided on the lower end face of the adjusting rod 3; a vertical limit slide groove 15 is provided on one side of the upper end of the support rod 2, a locking limit groove 8 is provided on one side of the vertical limit slide groove 15 on the upper end face of the support rod 2, a vertical adjustment slider 12 is provided on the inner side of the vertical limit slide groove 15, and a connecting slider 13 is provided on one side end face of the vertical adjustment slider 12.

[0032] It should be noted that the base plate 1, serving as the foundation for the entire OCR recognition device, is constructed of metal, ensuring the device's stability and durability. The surface of the base plate 1 has been treated with rust-proof and anti-slip finishes to enhance its practicality and aesthetics. A support rod 2 is mounted vertically on one side of the upper end of the base plate 1, supporting and securing the top plate 11 and connecting other components. The top plate 11 is secured to the top of the support rod 2, providing a stable mounting platform for the detection lens 5. The adjustment rod 3 is used to adjust the position and angle of the detection lens 5. The concave clamping groove 6 allows the user to easily secure or release the detection lens 5 for precise position adjustment. The adjustment rod 3, in conjunction with the locking limit groove 8, ensures that the adjusted position remains stable. The detection lens 5 is responsible for capturing the optical information of the text or image to be recognized and converting it into a digital signal for subsequent processing. The vertical limit groove 15 provides guidance and limiting for the vertical adjustment slider 12, ensuring its smooth vertical movement. The locking limit groove 8 secures the adjusted position to prevent accidental movement of the slider during operation. The vertical limit slide 15 is made of precision-machined metal guide rails to ensure smooth sliding and precise positioning of the slider. The vertical adjustment slider 12 slides within the vertical limit slide 15 and connects to the detection lens 5 via the connecting slider 13, enabling vertical adjustment of the detection lens 5. The connecting slider 13 serves as an intermediate connector, ensuring stability and flexibility during the adjustment process.

[0033] In the embodiment of the present invention, the vertical adjustment slider 12 is provided with a first locking knob 14 on the end surface away from the connecting slider 13 , and the concave clamping groove 6 is provided with a second locking knob 7 on the outer end surface away from the detection lens 5 .

[0034] It should be noted that the vertical adjustment slider 12 is a key component installed in the vertical limit slot 15 of the support rod 2, which allows the user to adjust the position of the detection lens 5 in the vertical direction by sliding. In order to ensure that the adjusted position is stable, a first locking knob 14 is provided on the end face of the vertical adjustment slider 12 away from the connecting slider 13. The first locking knob 14 cooperates with the vertical limit slot 15. When the user reaches the desired position by sliding the vertical adjustment slider 12, rotating the first locking knob 14 can activate the locking mechanism and firmly lock the vertical adjustment slider 12 in the current position to prevent it from accidentally moving due to external force or vibration. The concave clamping groove 6 is a groove structure on the adjustment rod 3 for fixing the detection lens 5. After the user places the detection lens 5 in the concave clamping groove 6 and preliminarily positions it, rotating the second locking knob 7 can activate the locking mechanism of the concave clamping groove 6 (such as a clamping block, a locking screw, etc.), and lock the detection lens 5 more firmly in the concave clamping groove 6 to prevent it from shaking or falling off during operation.

[0035] In this embodiment of the present invention, a support groove 9 is provided on the upper end face of the support rod 2, on the side away from the locking limit groove 8. A protective groove 10 is formed on the side end of the support groove 9. The inner wall of the protective groove 10 is made of a soft material, such as rubber or silicone, to provide cushioning and shock absorption. The support groove 9 ensures smooth movement of the sliding component along the predetermined path, while the protective groove 10 prevents accidental damage and impact during movement.

[0036] In an embodiment of the present invention, a support pad 4 is provided on the lower end surface of the base plate 1. The support pad 4 is a rubber member. There are multiple support pads 4, and they are arranged in an array on the lower end surface of the base plate 1. The support pad 4 serves as a buffer and support component between the base plate 1 and the placement surface (such as a desktop, the ground, etc.), and can provide stable support force to prevent the OCR recognition device from sliding or shaking during use, thereby ensuring the stability and recognition accuracy of the device. Multiple support pads 4 can provide uniform support force in different directions to prevent the device from tilting or deforming due to uneven force. The layout of the support pads 4 helps to further increase the stability and balance of the bottom of the device.

[0037] In the embodiment of the present invention, the detection lens 5 is electrically connected to the external control device.

[0038] It should be noted that an external control device is a device connected to the inspection lens that controls it, processes data, or provides instructions. It can be a computer, microcontroller, image processing unit (IPU), or any other electronic device with the appropriate interface and software. The external control device receives image data from the inspection lens, performs necessary processing and analysis, and then performs corresponding operations or issues instructions based on the results. The inspection lens and external control device are connected via a specific physical interface (such as USB, HDMI, Gigabit Ethernet, Camera Link, etc.).

[0039] In an embodiment of the present invention, the inner end surface of the adapter protection groove 10 is compatible with the outer end surface of the detection lens 5. By ensuring that the inner end surface of the adapter protection groove 10 is compatible with the outer end surface of the detection lens 5, the detection lens 5 can be accurately positioned and firmly fixed, preventing it from shaking or shifting during operation, thereby ensuring the accuracy and stability of image acquisition. Factors such as the lens outer diameter, length, and interface type are taken into consideration to ensure that the two can fit tightly on the contact surface without leaving any gaps. The outer end surface of the rotating rod on the side of the first locking knob 14 in the top view is compatible with the inner end surface of the locking limit groove 8 in the top view. The locking limit groove 8 is a groove structure that provides rotational guidance and limiting function for the first locking knob 14. The adaptive relationship between the two is crucial to ensuring the locking effect and preventing accidental movement of components. The shape, size, and rotation trajectory of the outer end surface of the rotating rod on the side of the first locking knob 14 match the inner end surface of the locking limit groove 8 to ensure that it can slide smoothly into and stay in the predetermined position during rotation.

[0040] In the embodiment of the present invention, the outer end surface of the connecting slider 13 in the top view matches the inner end surface of the concave clamping groove 6 in the top view, ensuring that when the connecting slider 13 is placed in the concave clamping groove 6, the two can fit tightly together without leaving any gaps. The connecting slider 13 and the concave clamping groove 6 are connected by a second locking knob 7.

[0041] In the embodiment of the present invention, the outer end surface of the adjusting rod 3 in the right-side viewing direction is adapted to the outer end surface of the support rod 2 in the right-side viewing direction, and the contours or outlines of the two in the vertical cross-section can match each other, thereby ensuring a tight fit without gaps when connected or docked, which helps to achieve stable installation and precise adjustment of the adjusting rod 3 on the support rod 2. A receiving groove 16 is formed on one end surface of the support rod 2.

[0042] In an embodiment of the present invention, one side end face of the receiving groove 16 is adapted to the lower side end face of the adjusting rod 3, and the inner side end face of the vertical limiting groove 15 is adapted to the outer side end face of the vertical adjusting slider 12. The receiving groove 16 takes into account the placement requirements of the adjusting rod 3 on its lower side, and the two can fit tightly on the contact surface to form a stable connection or support relationship. When the adjusting rod 3 is in an unworking state or needs to be temporarily fixed, its lower side end face can be inserted into the receiving groove 16 to obtain stable support. The vertical adjusting slider 12 can slide freely in the vertical limiting groove 15, but its sliding range is limited by the inner side end face of the vertical limiting groove 15. Through the adaptation relationship between the vertical limiting groove 15 and the vertical adjusting slider 12, the user can accurately control the position of the vertical adjusting slider 12 in the vertical direction.

[0043] In the embodiment of the present invention, the inner end face of the limit support chute 9 is adapted to the outer end face of the connecting slider 13, and the two can fit tightly on the contact surface, forming a stable support and sliding relationship. The connecting slider 13 can slide smoothly in the limit support chute 9 without shaking or getting stuck. The locking limit groove 8, the limit support chute 9, and the vertical limit chute 15 are at the same height in the main viewing direction. The dimensions of the three groove structures in the vertical direction are consistent, forming a unified and coordinated overall structure. Due to the same height, these groove structures can be more easily aligned and matched during installation and debugging, and the design of the same height also helps to enhance the stability of the entire structure.

[0044] When the present invention is in use, the staff installs the base plate 1 in a suitable position, and then the staff turns the second locking knob 7, and then adjusts the adjusting rod 3 to a suitable angle, and then the second locking knob 7 can be turned again to lock the position of the adjusting rod 3, and then the staff can turn the first locking knob 14 according to the needs of tobacco identification and detection, and then slide the vertical adjustment slider 12 in the vertical limit slide groove 15 to a suitable position, and then the staff can turn the first locking knob 14 to lock the position of the vertical adjustment slider 12, and then when the staff identifies the tobacco, it is placed on the upper end of the base plate 1, and the detection lens 5 can identify and detect the tobacco.

[0045] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
