Description

Technical Field

[0001] This application relates to the field of inkjet printing and scanning positioning technology, and in particular to an inkjet printing device with scanning positioning function. Background Technology

[0002] In the inkjet printing industry, inkjet printing technology continues to evolve, and inkjet printing equipment plays a vital role in numerous fields such as industrial production and commercial printing. As industries increasingly demand personalized and customized products, inkjet printing equipment needs to possess higher precision and adaptability to meet the printing requirements of diverse products. Advances in inkjet printing technology have not only improved production efficiency but also enhanced the aesthetics and added value of products, driving the development of related industries.

[0003] Traditional inkjet printers require workers to measure the product's dimensions, place it on the printing platform, and accurately move and position it to achieve precise printing. This method relies on manual operation, is cumbersome, demands high levels of skill and experience from workers, and is prone to human error. Later improved inkjet printers installed a scanning camera on the crossbeam of the printing carriage. During use, workers simply place the product on the printing platform, and the scanning camera scans the product's position and dimensions to locate the printing area, thus facilitating subsequent precise printing.

[0004] However, existing scanning positioning inkjet printers still have certain shortcomings in practical use. Because the products to be printed vary in specifications, including thickness and shape, and the distance between the scanning camera and the printing platform in existing scanning positioning inkjet printers is not adjustable, their applicability to different product specifications is limited, failing to adequately meet diverse printing needs, and thus requiring improvement. Utility Model Content

[0005] To address the issue of limited applicability of existing scanning and positioning inkjet printers, this application provides an inkjet printing device with scanning and positioning functionality.

[0006] This application provides a printing device with scanning and positioning function, which adopts the following technical solution: A printing device with scanning and positioning function includes a base and a printing platform mounted on the base. A crossbeam is provided above the printing platform. Both ends of the crossbeam are slidably mounted on the base, and a printing carriage is slidably mounted on the crossbeam. A scanning camera for scanning the size and position of a product is provided on the crossbeam along its length. The length of the scanning camera is greater than the length of the printing platform, and the distance between the scanning camera and the printing platform is adjustable.

[0007] By adopting the above technical solution, the base supports the entire printing device, the printing platform provides a placement position for the product to be printed, the crossbeam can slide on the base to facilitate position adjustment to adapt to different printing needs, and the printing head slides on the crossbeam to realize the printing operation on the product; the scanning camera is set along the length of the crossbeam and can automatically scan the size and position of the product. Its length is greater than the length of the printing platform to ensure that the scanning can fully cover the printing platform and achieve accurate positioning of the product printing area. At the same time, the distance between the scanning camera and the printing platform is adjustable to adapt to the scanning positioning of products of different specifications, improve the applicability of the printing device, and meet diverse printing needs.

[0008] Preferably, both ends of the scanning camera are fixedly connected to sliding seats that slide in cooperation with the crossbeam, and the crossbeam is provided with a driving mechanism for driving the sliding seats to slide.

[0009] By adopting the above technical solution, the sliding seats at both ends of the scanning camera form a stable sliding fit with the crossbeam. At the same time, the sliding seats are driven by the drive mechanism to slide, which can realize the synchronous lifting and lowering of both ends of the scanning camera. This allows for flexible adjustment of the distance between the scanning camera and the printing platform, enabling the device to adapt to products of different specifications on the printing platform and improving the adaptability of the printing device to diverse products.

[0010] Preferably, the driving mechanism includes a drive motor, a worm, a worm wheel, a gear, and a rack. The drive motor is fixedly connected to the crossbeam, and the worm is coaxially fixedly connected to the output shaft of the drive motor. The worm meshes with the worm wheel, and the worm wheel is coaxially fixedly connected to the gear. The gear meshes with the rack, and the rack is fixedly connected to the sliding seat.

[0011] By adopting the above technical solution, the drive motor provides power for the lifting and lowering of the scanning camera. Its output shaft drives the worm gear fixedly connected to it to rotate, and the worm gear meshes with the worm wheel to transmit power to the worm wheel. The worm wheel is fixedly connected to the gear on the same axis, thereby driving the gear to rotate. At the same time, the gear meshes with the rack fixed on the sliding seat, thereby converting the rotation of the gear into the linear motion of the sliding seat, realizing the lifting and lowering of the scanning camera on the crossbeam, which facilitates the scanning camera to scan and position products of different specifications.

[0012] Preferably, there are two gears located at both ends of the scanning camera, and there are also two racks corresponding to the number and position of the gears. Each rack is fixedly connected to a sliding seat adjacent to it. A rotating shaft is provided between the two gears, and the two ends of the rotating shaft are respectively coaxially fixedly connected to the two gears.

[0013] By adopting the above technical solution, setting two gears and corresponding racks, and connecting the two gears with a rotating shaft, the scanning camera can be subjected to force and raised and lowered synchronously at both ends, avoiding tilting or jamming of the scanning camera during raising and lowering, ensuring consistent distance adjustment between the scanning camera and the printing platform, improving the accuracy of the device in scanning and positioning the product, and ensuring stable printing quality.

[0014] Preferably, the scanning camera is provided with a limiting mechanism to prevent the scanning camera from contacting the printing platform, and the base is provided with a control unit, and the limiting mechanism and the drive motor are both electrically connected to the control unit.

[0015] By adopting the above technical solution, the limiting mechanism can monitor the contact between the scanning camera and the printing platform in real time and feed it back to the control unit. At the same time, the control unit can control the operation status of the drive motor according to the information fed back by the limiting mechanism, so as to prevent the scanning camera from falling too far during the descent process and colliding with the printing platform, thus ensuring the safe use of the scanning camera.

[0016] Preferably, the limiting mechanism includes a sensing module, a connecting block, a bolt, and a spring sleeved on the bolt. The sensing module is electrically connected to the control unit. The sensing module and the connecting block are both fixedly connected to the end of the scanning camera. The connecting block is located on the side of the sensing module closer to the printing platform. The bolt passes through the connecting block and abuts against the sensing module. The two ends of the spring are fixedly connected to the connecting block and the bolt, respectively.

[0017] By adopting the above technical solution, the connecting block is fixed at the end of the scanning camera and located on the side of the sensing module near the printing platform, providing support and installation position for the bolt. The bolt passes through the connecting block and abuts against the sensing module. When the scanning camera approaches the printing platform, the bolt can trigger the sensing module. At the same time, the sensing module can transmit the monitored information to the control unit, which can then control the operation of the drive motor based on the information. The spring is sleeved on the bolt and its two ends are fixedly connected to the connecting block and the bolt respectively, serving to connect the bolt and the connecting block. At the same time, after the drive motor drives the scanning camera to rise, the spring can drive the bolt to reset for subsequent accurate monitoring.

[0018] Preferably, a reinforcing rod for preventing deformation of the scanning camera is fixedly connected along its length, and the two ends of the reinforcing rod are respectively fixedly connected to two sliding seats.

[0019] By adopting the above technical solutions, the reinforcing rod can enhance the structural stability of the scanning camera, prevent the scanning camera from deforming due to external forces or its own gravity during use, and ensure the normal operation and scanning accuracy of the scanning camera.

[0020] Preferably, the drive motor is equipped with a handwheel for manual control.

[0021] By adopting the above technical solution and setting a handwheel on the drive motor, the drive motor can be manually controlled in some special situations (such as power failure, automatic control failure, etc.), which enhances the flexibility of the printing device operation and its ability to cope with special situations.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The distance between the scanning camera and the printing platform is adjustable, which can adapt to the printing needs of products of different specifications and improve the applicability of the printing device. At the same time, the length of the scanning camera is greater than the length of the printing platform, which can ensure that the printing platform is fully covered during scanning, achieve precise positioning of the product printing area, and improve scanning efficiency and accuracy. 2. Both the limit mechanism and the drive motor are electrically connected to the control unit, so that the control unit can control the operating status of the drive motor according to the information fed back by the limit mechanism, to prevent the scanning camera from falling too far during the descent and colliding with the printing platform, thus ensuring the safe use of the scanning camera. 3. The reinforcing rod can prevent the scanning camera from deforming due to external forces or its own weight during use, thus improving the structural stability of the scanning camera. The handwheel on the drive motor allows workers to manually control the rotation of the drive motor output shaft in special circumstances, thereby manually controlling the raising and lowering of the scanning camera, enhancing the flexibility of the printing device operation and its ability to cope with special situations.

[0025] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0026] This application discloses a printing device with scanning and positioning functions.

[0027] Reference Figure 1 and Figure 2 A printing device with scanning and positioning function includes a base 1 and a printing platform 11 mounted on the base 1. A crossbeam 2 is arranged above the printing platform 11 along its length direction, and both ends of the crossbeam 2 are slidably mounted on the base 1 along the width direction of the printing platform 11. In this embodiment, the crossbeam 2 includes a main beam 21 mounted above the printing platform 11 and sliding plates 22 fixedly connected to both ends of the main beam 21 by bolts 73. Each of the sliding plates 22 is slidably engaged with the base 1 by a linear motor. A printing head 3 is slidably mounted on the main beam 21 of the crossbeam 2. In this embodiment, the printing head 3 is also slidably engaged with the main beam 21 along the length direction of the printing platform 11 by a linear motor. A scanning camera 4 for scanning product size and position is arranged on the main beam 21 of the crossbeam 2 along its length direction. The length of the scanning camera 4 is greater than the length of the printing platform 11, and the distance between the scanning camera 4 and the printing platform 11 is adjustable.

[0028] In practical use, the worker first adjusts the distance between the scanning camera 4 and the printing platform 11 according to the actual size of the product, and then places the product on the printing platform 11. Next, the sliding plates 22 at both ends of the main beam 21, driven by linear motors, drive the scanning camera 4 to scan the size and position of the product on the printing platform 11. The length of the scanning camera 4 is greater than the length of the printing platform 11, which ensures that the scanning fully covers the printing platform 11, thereby achieving precise positioning of the product printing area. After scanning, the printing carriage 3 on the main beam 21 moves along the length of the printing platform 11 under the drive of the linear motor, while cooperating with the main beam 21 to move along the width of the printing platform 11, achieving precise printing of the product. Overall, this printing device can adapt to the scanning positioning and printing of products of different specifications, improving the applicability of the printing device and meeting diverse printing needs.

[0029] Reference Figure 1 and Figure 2 Both ends of the scanning camera 4 are fixedly connected to sliding seats 5 that slide with the slide plate 22 via bolts 73. In this embodiment, each sliding seat 5 includes a sliding plate 51 fixedly connected to the scanning camera 4 via bolts 73 and a sliding block 52 fixedly connected to the sliding plate 51 via welding. Each slide plate 22 is fixedly connected to a guide rail 221 via bolts 73 on the side near the sliding seat. Each sliding block 52 has a groove that fits into the guide rail 221, and each sliding block 52 slides with the adjacent guide rail 221 through the groove. The slide plate 22 of the crossbeam 2 is provided with a drive mechanism 6 for driving the sliding seat 5 to slide. The drive mechanism 6 includes a drive motor 61. The device includes a worm gear 62, a worm wheel 63, a gear 64, a rack 65, and a rotating shaft 66. The drive motor 61 is fixedly connected to the slide plate 22 at one end of the main beam 21 by bolts 73. The worm gear 62 is coaxially fixedly connected to the output shaft of the drive motor 61, and the worm wheel 63 meshes with the worm gear 62. There are two gears 64, located at both ends of the scanning camera 4. There are also two racks 65, corresponding to the number and position of the gears 64. Each rack 65 is fixedly connected to the adjacent sliding block 52 by welding, and each rack 65 meshes with its adjacent gear 64. The two ends of the rotating shaft 66 are coaxially fixedly connected to the two gears 64 respectively, and the worm wheel 63 is coaxially fixedly connected to its adjacent gear 64.

[0030] In practical use, when the worker adjusts the distance between the scanning camera 4 and the printing platform 11, the drive motor 61 provides power to drive the worm gear 62 to rotate. Since the worm wheel 63 meshes with the worm gear 62, the rotation of the worm gear 62 will drive the worm wheel 63 to rotate synchronously. Because the worm wheel 63 is coaxially and fixedly connected to its adjacent gear 64, and the two gears 64 are coaxially and fixedly connected to both ends of the rotating shaft 66, the rotation of the worm wheel 63 will drive the two gears 64 to rotate synchronously. The two gears 64 mesh with their corresponding racks 65, thereby driving the sliding block 52, which is fixedly connected to the rack 65, to move along the guide rail 221. The sliding block 52 simultaneously drives the sliding plate 51, which is fixedly connected to the scanning camera 4, to move, thereby achieving stable lifting and lowering of the scanning camera 4 between the two sliding plates 22. This allows the distance between the scanning camera 4 and the printing platform 11 to be flexibly adjusted, facilitating the scanning camera 4 to scan and position products of different specifications. A drive motor 61 is provided, and power is transmitted synchronously through a rotating shaft 66 between two gears 64. This allows the scanning camera 4 to be subjected to force and lifted and lowered synchronously at both ends, ensuring that the distance between the scanning camera 4 and the printing platform 11 is adjusted consistently, thus improving the accuracy of the device in scanning and positioning products.

[0031] Reference Figure 1 and Figure 2 The drive motor 61 is equipped with a handwheel 611 for manual control. In this embodiment, the end of the output shaft of the drive motor 61 away from the worm gear 62 passes through the drive motor 61 and is coaxially and fixedly connected to the handwheel 611. In actual use, when encountering some special situations (such as power failure, automatic control failure, etc.), the worker can manually operate the drive motor 61 through the handwheel 611, which enhances the flexibility of the printing device operation and the ability to cope with special situations.

[0032] Reference Figure 1 , Figure 2 as well as Figure 3 The scanning camera 4 is provided with a limiting mechanism 7 at one end to prevent the scanning camera 4 from contacting the printing platform 11. The limiting mechanism 7 includes a sensing module 71, a connecting block 72, a bolt 73, and a spring 74 sleeved on the bolt 73. In this embodiment, the sensing module 71 is a pressure sensor. The sensing module 71 and the connecting block 72 are both fixedly connected to the end of the scanning camera 4 by the bolt 73. The connecting block 72 is located on the side of the sensing module 71 closer to the printing platform 11. The bolt 73 passes through the connecting block 72 and forms an abutment with the sensing module 71. The two ends of the spring 74 are fixedly connected to the connecting block 72 and the bolt 73 by welding. A control unit 12 is fixedly installed on the base 1. The sensing module 71 and the drive motor 61 are both electrically connected to the control unit 12.

[0033] In practical use, when the scanning camera 4 descends to approach the printing platform 11, the bolt 73 will first contact the printing platform 11 and be subjected to upward pressure. This pressure is transmitted to the sensing module 71 (pressure sensor) through the bolt 73. After detecting the pressure change, the sensing module 71 transmits the signal to the control unit 12. Upon receiving the signal, the control unit 12 immediately controls the drive motor 61 to stop operating, thereby preventing the scanning camera 4 from continuing to descend and contact the printing platform 11. This effectively avoids collision damage between the scanning camera 4 and the printing platform 11, improving the safety and reliability of the device. At the same time, the spring 74 can automatically reset the bolt 73 after the drive motor 61 drives the scanning camera 4 to rise, so as to facilitate subsequent accurate monitoring.

[0034] Reference Figure 1 , Figure 2 as well as Figure 4 In this embodiment, the end of the scanning camera 4 furthest from the limiting mechanism 7 is fixedly connected to a detection plate 8 by bolts 73, and a photoelectric sensor 222 is fixedly installed on the slide plate 22 near the detection plate 8. Two photoelectric sensors 222 are arranged along the lifting direction of the scanning camera 4, and each photoelectric sensor 222 is electrically connected to the control unit 12. In actual use, when the detection plate 8 moves with the lifting of the scanning camera 4, the two photoelectric sensors 222 can monitor the position change of the detection plate 8 in real time and transmit the signal to the control unit 12. The control unit 12 determines the current position of the scanning camera 4 based on the received signal. If the scanning camera 4 is within the normal lifting range, the drive motor 61 continues to operate. If the position of the detection plate 8 exceeds the preset safety range, the control unit 12 immediately controls the drive motor 61 to stop operating, preventing the scanning camera 4 from malfunctioning or being damaged due to excessive lifting, and further improving the stability and safety of the device operation.

[0035] Reference Figure 1 and Figure 5 The scanning camera 4 is fixedly connected along its length to a reinforcing rod 9 for preventing deformation of the scanning camera 4. In this embodiment, the reinforcing rod 9 is provided with multiple reinforcing members 91 at equal intervals along its length. The two ends of any one of the reinforcing members 91 are fixedly connected to the reinforcing rod 9 and the scanning camera 4 respectively by bolts 73. The two ends of the reinforcing rod 9 are also fixedly connected to the sliding plates 51 in the two sliding seats 5 by bolts 73. In actual use, the reinforcing rod 9 can enhance the structural stability of the scanning camera 4 and prevent the scanning camera 4 from deforming due to external forces or its own weight during use, thereby ensuring the normal operation and scanning accuracy of the scanning camera 4.

[0036] The implementation principle of this application embodiment is as follows: a basic structure is built by a base 1, a printing platform 11, and a crossbeam 2 that can slide along the width direction of the printing platform 11. The printing head 3 on the crossbeam 2 can slide along the length direction of the crossbeam 2. At the same time, a scanning camera 4 with a length covering the printing platform 11 is provided on the main beam 21 of the crossbeam 2. The scanning camera 4 is raised and lowered by cooperating with the guide rail 221 on the slide plate 22 through the sliding seat 5. The driving mechanism 6, which is composed of a drive motor 61, a worm gear 62, a worm wheel 63, a gear 64, a rack 65, and a rotating shaft 66, provides the lifting power. It can be manually controlled via handwheel 611; during lifting, it works in conjunction with limit mechanism 7, photoelectric sensor 222 and control unit 12 to achieve lifting safety limit, while reinforcing rod 9 and reinforcing parts 91 ensure the structural stability of scanning camera 4; in use, first adjust the height of scanning camera 4 according to the product size, then slide the crossbeam 2 to drive scanning camera 4 to fully scan the product size and position for accurate positioning, and finally complete the accurate printing by the coordinated sliding of printing head 3 and crossbeam 2. The whole device can be adapted to products of different specifications, improving the applicability, accuracy and safety of the device.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
