Description

Technical Field

[0001] This utility model relates to an important component of a printer, and in particular to a longitudinal scanning and positioning system. Background Technology

[0002] In the inkjet printing industry, whether it's a roll-to-roll or flatbed printer, the printed graphics are pre-designed, requiring precise positioning of the printing material during the printing process. Traditional positioning is usually done manually or with custom tooling for different products, necessitating alignment of the material with a ruler and positioning each product individually. This is time-consuming, inefficient, and the tooling costs are substantial, especially for small-batch production. To address these shortcomings, some printers use scanning cameras similar to those in home printers to scan the entire printing surface, generating graphic information about the printing platform, facilitating the placement of printing materials. However, quickly focusing and capturing images with the scanning camera of a large printer remains a challenge for the inkjet printing industry. Utility Model Content

[0003] The purpose of this invention is to provide a longitudinal scanning positioning system that can solve at least one of the above problems.

[0004] According to one aspect of the present invention, a longitudinal scanning positioning system is provided, including a first mounting plate, a second mounting plate, a scanning camera, and a lifting device. The first mounting plate and the second mounting plate are arranged opposite to each other. The two ends of the scanning camera are respectively disposed on the first mounting plate and the second mounting plate. The lifting device includes a motor and a lifting screw. The motor is fixed on the first mounting plate. The lifting screw is connected to the output shaft of the motor and is vertically arranged. The scanning camera is connected to the lifting screw and can move up and down along the lifting screw.

[0005] The beneficial effects of this utility model are as follows: by providing a lifting device, the motor can drive the lifting screw to rotate, thereby enabling the scanning camera to move up and down along the lifting screw. When the focus of the scanning camera is adjusted, the scanning camera will automatically take a picture without the need for manual adjustment of the scanning camera according to the actual printing material. This facilitates the rapid focusing and taking of pictures by the scanning camera and ensures printing efficiency.

[0006] In some embodiments, the lifting device further includes a synchronous pulley assembly and a synchronous belt. The synchronous pulley assembly is connected to the output shaft of the motor via the synchronous belt, and the lifting screw is connected to the synchronous pulley assembly. This facilitates the motor driving the lifting screw to rotate.

[0007] In some embodiments, the synchronous pulley assembly includes a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a fourth synchronous pulley. The first synchronous pulley is sleeved on the output shaft of the motor, the synchronous belt is wound around each synchronous pulley, the lifting screw is mounted on a second mounting plate, and the fourth synchronous pulley is sleeved on the top of the lifting screw. Thus, the multiple synchronous pulleys facilitate the winding of the synchronous belt, enable the motor to drive the lifting screw to rotate smoothly, and ensure smooth lifting and lowering of both ends of the scanning camera.

[0008] In some embodiments, a longitudinal scanning positioning system further includes a fixing plate, on which the motor is mounted. The fixing plate is fixed to the top of a first mounting plate, a second synchronous pulley is mounted on the fixing plate, and a third synchronous pulley is mounted on the first mounting plate. Thus, by providing a fixing plate, the installation of the motor and related structures is facilitated.

[0009] In some embodiments, the second mounting plate is provided with a lifting screw fixing seat, and the lifting screw is sleeved on the lifting screw fixing seat. This facilitates the installation of the lifting screw on the second mounting plate and meets the rotation requirements of the lifting screw.

[0010] In some embodiments, both the first and second mounting plates are provided with vertical guide rails, and sliders are fixed at both ends of the scanning camera, with the sliders cooperating with the vertical guide rails on the corresponding sides. Thus, by providing vertical guide rails, the raising and lowering of the scanning camera can be guided, thereby facilitating the smooth raising and lowering of the scanning camera.

[0011] In some embodiments, a longitudinal scanning positioning system further includes a connector. One end of the scanning camera near the second mounting plate is connected to the slider via the connector. The connector is sleeved on the lifting screw and threadedly engages with it. Thus, by providing the connector, the engagement between the scanning camera and the lifting screw is facilitated, allowing the scanning camera to move synchronously with the connector.

[0012] In some embodiments, a longitudinal scanning positioning system further includes a tensioning wheel and an adjusting element. The synchronous belt is wound around the tensioning wheel, the adjusting element is mounted on a fixed plate, and the tensioning wheel is mounted on the adjusting element. Thus, by providing a tensioning wheel, the tension of the synchronous belt can be adjusted, preventing it from becoming too loose or too slack during use, ensuring smooth rotation of the lifting screw driven by the motor, and meeting usage requirements.

[0013] In some embodiments, a longitudinal scanning positioning system further includes a first limit switch and a second limit switch, with the first limit switch located above the second limit switch. Both the first and second limit switches are electrically connected to a motor. Thus, by providing two limit switches, the vertical movement of the scanning camera can be limited, preventing the scanning camera from hitting the printing platform downwards or other structures upwards.

[0014] In some embodiments, a longitudinal scanning positioning system further includes a camera image sensor switch, which is fixed to one end of the scanning camera. Thus, by providing the camera image sensor switch, once the scanning camera is focused, the camera image sensor switch controls the scanning camera to automatically take a picture.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Reference Figures 1-3 A longitudinal scanning positioning system includes a first mounting plate 1, a second mounting plate 2, a scanning camera 3, and a lifting device 4. The first mounting plate 1 and the second mounting plate 2 are arranged opposite to each other. The two ends of the scanning camera 3 are respectively mounted on the first mounting plate 1 and the second mounting plate 2. The lifting device 4 includes a motor 41 and a lifting screw 42. The motor 41 is fixed on the first mounting plate 1. The lifting screw 42 is connected to the output shaft of the motor 41 and is vertically arranged. The scanning camera 3 is connected to the lifting screw 42 and can move up and down along the lifting screw 42.

[0021] In actual use, mounting back plates 90 are fixed to the outer sides of both the first mounting plate 1 and the second mounting plate 2 by screws. The longitudinal scanning positioning system 100 is fixed to the longitudinal moving beam 60 of the printer by the mounting back plates 90. The inkjet printing carriage 70 can move along the longitudinal moving beam and is located above the printing work platform 80 (e.g., Figure 4 (As shown). During use, the printing material is placed on the printing platform, and the lifting device 4 can drive the scanning camera 3 to move up and down, so as to take real-time focus and pictures of the printing material, or print graphic information.

[0022] A longitudinal scanning positioning system also includes a camera image sensor switch 50, which is fixed to one end of the scanning camera 3 and electrically connected to the scanning camera via a wire. The camera image sensor switch 50 controls the scanning camera 3 to take pictures. Therefore, when the scanning camera 3 is raised or lowered into position and automatically adjusts its focus, the camera image sensor switch 50 is triggered, realizing the automatic taking of pictures by the scanning camera 3.

[0023] The lifting device 4 also includes a synchronous pulley assembly 43 and a synchronous belt 44. The synchronous pulley assembly 43 is connected to the output shaft of the motor 41 through the synchronous belt 44, and the lifting screw 42 is connected to the synchronous pulley assembly 43.

[0024] The synchronous pulley assembly 43 includes a first synchronous pulley 431, a second synchronous pulley 432, a third synchronous pulley 433, and a fourth synchronous pulley 434. The first synchronous pulley 431 is sleeved on the output shaft of the motor 41, and the synchronous belt 44 is wound around each synchronous pulley. The lifting screw 42 is mounted on the second mounting plate 2, and the fourth synchronous pulley 434 is sleeved on the top of the lifting screw 42. Specifically, when the motor 41 is working, the first synchronous pulley 431 rotates synchronously with the output shaft of the motor, thereby driving the synchronous belt 44 wound around the first synchronous pulley 431 and the other synchronous pulleys for transmission. Under the transmission action of the synchronous belt 44, the fourth synchronous pulley 434 can be driven to rotate, thereby causing the fourth synchronous pulley 434 to drive the lifting screw 42 to rotate. The lifting screw 42 drives the scanning camera 3 to rise and fall relative to the lifting screw 42. By controlling the rotation direction of the motor 41, the scanning camera 3 can be controlled to move up or down along the lifting screw 42, thereby automatically focusing on different printing materials and taking pictures, without the need for manual focusing of the scanning camera, thus improving printing efficiency.

[0025] The longitudinal scanning positioning system of this utility model also includes a fixing plate 5, a motor 41 mounted on the fixing plate 5, the fixing plate 5 being fixed to the top of a first mounting plate 1 by screws, a second synchronous pulley 432 being disposed on the fixing plate 5, and a third synchronous pulley 433 being disposed on the first mounting plate 1. The housing of the motor 41 is fixed to the bottom of the fixing plate 5 by screws; the output shaft of the motor 41 passes through the fixing plate 5 and extends upward, facilitating the fitting of the first synchronous pulley 431 and the winding of the synchronous belt 44.

[0026] The second mounting plate 2 is provided with a lifting screw fixing seat 6, and the lifting screw 42 is sleeved on the lifting screw fixing seat 6. The bottom end of the lifting screw 42 is sleeved on the second mounting plate 2, and the top end is sleeved in the lifting screw fixing seat 6 and extends upward, so as to facilitate the mounting of the fourth synchronous pulley 434 on the lifting screw 42. Therefore, when the fourth synchronous pulley 434 rotates, it can drive the lifting screw 42 to rotate.

[0027] Both the first mounting plate 1 and the second mounting plate 2 are equipped with vertical guide rails 7, and sliders 8 are fixed at both ends of the scanning camera 3. The sliders 8 cooperate with the vertical guide rails 7 on the corresponding sides. This facilitates the lifting and lowering of both ends of the scanning camera 3 along the corresponding vertical guide rails 7, and promotes the synchronous lifting and lowering of both ends of the scanning camera.

[0028] The longitudinal scanning positioning system of this utility model also includes a connector 9. One end of the scanning camera 3 near the second mounting plate 2 is connected to the slider 8 via the connector 9. The connector 9 is sleeved on the lifting screw 42 and is threadedly engaged with the lifting screw 42. The housing of the scanning camera 3 is fixed to the connector 9 with screws, and the connector 9 is also fixed to the corresponding slider 8 with screws, thus facilitating the engagement of the scanning camera 3 with the lifting screw 42 via the connector 9. Since the connector 9 and the lifting screw 42 are threadedly engaged, when the lifting screw 42 rotates, the connector 9 can move upward or downward relative to the lifting screw 42, realizing the upward or downward movement of the scanning camera 3.

[0029] The longitudinal scanning positioning system also includes a first limit switch 30 and a second limit switch 40. The first limit switch 30 is located above the second limit switch 40, and both the first limit switch 30 and the second limit switch 40 are electrically connected to the motor 41. The first limit switch 30 limits the highest position of the scanning camera 3, and the second limit switch 40 limits the lowest position of the scanning camera 3. When the scanning camera 3 moves downward along the lifting screw 42 to the position of the second limit switch 40, the second limit switch 40 senses the scanning camera 3 and sends a signal to the external controller. The external controller then controls the motor 41 to stop working, preventing the scanning camera 3 from continuing to move downward and thus avoiding the scanning camera 3 hitting the printing platform. Similarly, when the scanning camera 3 moves upward to the first limit switch 30, the motor 41 stops working to prevent the scanning camera 3 from rising to its limit position and causing motor overload.

[0030] The longitudinal scanning positioning system of this utility model also includes a tensioning pulley 10 and an adjusting component 20. The synchronous belt 44 is wound around the tensioning pulley 10, and the adjusting component 20 is located on the fixed plate 5. The tensioning pulley 10 is located on the adjusting component 20. To facilitate the installation of the synchronous belt 44, the synchronous belt is first easily installed, and then the tensioning pulley 10 is moved outward by adjusting the adjusting component, thereby making the tensioning pulley 10 tension the synchronous belt, making the synchronous belt easy to install. At the same time, the synchronous belt 44 will have changes in tension due to thermal expansion and contraction in winter or summer. The synchronous belt will also loosen over time. The tensioning pulley adjustment allows for adjustment at any time according to the on-site working environment.

[0031] Specifically, the adjusting component 20 includes a mounting base 201 and an adjusting screw 202. The rotating shaft 101 of the tensioning wheel 10 is connected to the adjusting screw 202. The mounting base 201 is fixed to the lower end of the fixing plate 5 and is U-shaped. One end of the adjusting screw 202 is located outside the mounting base 201, and the other end passes through one side of the mounting base and the rotating shaft 101, and is sleeved on the other side of the mounting base. An opening slot is provided on one side of the fixing plate 5. One end of the rotating shaft 101 is threaded into the adjusting screw 202, and the other end passes through the opening slot and extends upward to engage with the tensioning wheel 10, facilitating the installation of the tensioning wheel 10. The opening slot on the fixing plate 5 can limit the rotation of the rotating shaft 101 of the tensioning wheel 10, preventing the rotating shaft 101 from rotating when the adjusting screw 202 rotates. Therefore, when the tension of the synchronous belt needs to be adjusted, the tensioning wheel 10 is adjusted to adjust the distance between the tensioning wheel 10 and each synchronous pulley. Specifically, when the adjusting screw 202 is turned, the rotating shaft 101 sleeved on the adjusting screw 202 can move relative to the adjusting screw 202, thereby causing the tensioning wheel 10 to move, thus tightening or loosening the timing belt. In actual operation, the direction of turning the adjusting screw 202 can be controlled to adjust the direction of movement of the tensioning wheel 10, thereby adjusting the tension of the timing belt 44 to meet actual usage requirements.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
