Detailed Implementation

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Please refer to Figures 1 to 6As shown, an embodiment of the present invention provides a photoresist auxiliary process device for clear inkjet printing on the nozzle of a metal tube, comprising: a base 1 and a protective cover 2 fixedly connected to the top of the base 1. An auxiliary positioning component 3 for positioning and rotating the metal tube to be printed is installed on one side of the protective cover 2, and an inkjet printing component 4 for inkjet printing on the nozzle of the metal tube is installed on the other side of the protective cover 2. By adopting the above technical solution, the auxiliary positioning component 3 and the coding component 4 are respectively set on both sides of the protective cover 2. The layout is reasonable, making the overall structure of the device compact, easy to operate and maintain, and providing a stable spatial environment for the positioning, rotation and coding of the metal tube.

[0024] In order to achieve the initial positioning of the metal tube to be printed, in this embodiment: the auxiliary positioning component 3 includes a rotatable fixed base 301. The side of the fixed base 301 is provided with a fixing groove 3011 for accommodating the metal tube to be printed. The fixing groove 3011 provides an initial placement position for the metal tube to be printed, so that the metal tube can be quickly and accurately placed on the fixed base 301, laying the foundation for subsequent precise positioning and rotation operations.

[0025] To further enhance the positioning stability of the metal tube to be printed, in this embodiment: a reinforcing rod 302 is fixedly connected to the top and bottom of the side of the fixed base 301, and a reinforcing ring 3021 for positioning the metal tube to be printed is fixedly connected to the ends of the two reinforcing rods 302. The reinforcing ring 3021 is connected to the fixed base 301 through the reinforcing rod 302. After the metal tube is placed in the fixed groove 3011, the reinforcing ring 3021 can further constrain the metal tube from the outside, enhance the stability of the metal tube on the fixed base 301, and prevent shaking or displacement during rotation.

[0026] To ensure that the metal tube is firmly fixed in the fixing groove 3011, in this embodiment, the top and bottom of the reinforcing ring 3021 are provided with set screws 303 for fixing the metal tube. The set screws 303 allow the operator to precisely fix the metal tube by tightening the set screws 303 according to the diameter of the metal tube, ensuring that the metal tube will not loosen on the fixing seat 301 and ensuring the smooth operation of the rotation and coding process.

[0027] To prevent damage to the metal tube from collisions within the fixing groove 3011 and to ensure accurate positioning of the metal tube end, in this embodiment, an abutment pad 304 is fixedly connected to the side of the inner wall of the fixing seat 301. The abutment pad 304 acts as a buffer, preventing direct collision between the metal tube end and the inner wall of the fixing seat 301, thus avoiding damage. Simultaneously, it provides a clear positioning reference for the metal tube end, ensuring that the metal tube accurately reaches the predetermined position each time it is placed, improving the accuracy and consistency of positioning.

[0028] To achieve the rotation of the fixed base 301, thereby driving the metal tube to rotate to meet the coding requirements, in this embodiment, the auxiliary positioning component 3 further includes a drive motor 305 for driving the fixed base 301 to rotate. The drive motor 305 is fixedly connected to one side of the base 1, and the output shaft of the drive motor 305 is fixedly connected to the side of the fixed base 301. The drive motor 305 provides the power source for the rotation of the fixed base 301. By controlling the operation of the drive motor 305, the rotation speed and angle of the fixed base 301 can be precisely controlled, thereby driving the metal tube to rotate according to the predetermined requirements, so that the opening of the metal tube can uniformly receive the coding operation and improve the coding quality.

[0029] To ensure the stability of the fixed base 301 during rotation, in this embodiment, L-shaped limiting slide rods 306 are fixedly connected to both the top and bottom of the fixed base 301. An annular groove 3061 matching the L-shaped limiting slide rod 306 is provided on the side of the inner wall of the protective cover 2. The cooperation between the L-shaped limiting slide rod 306 and the annular groove 3061 provides guidance and limitation for the rotation of the fixed base 301. During the rotation of the fixed base 301, the L-shaped limiting slide rod 306 slides along the annular groove 3061, ensuring that the fixed base 301 will not deviate or shake, thus guaranteeing the smoothness and accuracy of the rotation.

[0030] To further reduce the frictional force when the L-shaped limiting slide rod 306 slides within the annular groove 3061 and improve the smoothness of rotation, in this embodiment: a limiting ball 3062 is provided at the end of the L-shaped limiting slide rod 306, and the end of the L-shaped limiting slide rod 306 is rolledly connected to the inner wall of the annular groove 3061 through the limiting ball 3062. The limiting ball 3062 transforms sliding friction into rolling friction, greatly reducing the frictional force between the L-shaped limiting slide rod 306 and the inner wall of the annular groove 3061, making the rotation of the fixed seat 301 easier and smoother, reducing energy loss, reducing component wear, and extending the service life of the device.

[0031] To achieve multi-functional inkjet printing on the metal tube opening, in this embodiment: the inkjet printing assembly 4 includes a rotatable inkjet printing base 401, a QR code printhead 4012 is mounted on the top of the side of the inkjet printing base 401, and a photoresist printhead 4011 is mounted on the bottom of the side of the inkjet printing base 401. The rotatable design of the inkjet printing base 401 and the mounting of the QR code printhead 4012 and the photoresist printhead 4011 enable the device to first spray photoresist onto the metal tube opening through the photoresist printhead 4011. After the photoresist has cured, the inkjet printing base 401 is rotated to align the QR code printhead 4012 with the tube opening for QR code printing. This integrates multiple inkjet printing functions, meets different inkjet printing needs, and improves production efficiency.

[0032] To achieve precise movement and rotation of the inkjet printer base 401, ensuring accurate alignment of the printhead with the metal tube opening, in this embodiment, the inkjet printer assembly 4 further includes an electric cylinder 402 for laterally driving the inkjet printer base 401. A reversible motor 4021 for driving the rotation of the inkjet printer base 401 is mounted on the output end of the electric cylinder 402, and the output shaft of the reversible motor 4021 is fixedly connected to the side of the inkjet printer base 401. The electric cylinder 402 can precisely control the lateral movement distance of the inkjet printer base 401, enabling it to quickly and accurately reach the designated position. The reversible motor 4021 provides power for the rotation of the inkjet printer base 401. By controlling the forward and reverse rotation of the motor 4021, the inkjet printer base 401 can rotate flexibly, thereby accurately aligning the QR code printhead 4012 or photoresist printhead 4011 with the metal tube opening, ensuring the accuracy and clarity of the inkjet printing.

[0033] The working principle of this utility model is as follows: When printing inkjet printing on the opening of a metal tube, the operator first passes one end of the metal tube through the reinforcing ring 3021 and inserts it into the fixing groove 3011 on the side of the fixing base 301, so that the end of the metal tube is tightly abutted against the abutment pad 304. Then, the set screw 303 is tightened to achieve convenient and stable positioning of the metal tube to be printed. Next, the electric cylinder 402 is started, which pushes the inkjet printing base 401 to move laterally. At the same time, the forward and reverse motor 4021 drives the inkjet printing base 401 to rotate, so that the photoresist nozzle 4011 is accurately aligned with the opening of the clamped metal tube. Subsequently, photoresist is sprayed onto the opening through the photoresist nozzle 4011. After the photoresist has cured, the inkjet printing base 401 is rotated again by the forward and reverse motor 4021, so that the QR code nozzle 4012 is aligned with the opening. Finally, the QR code is sprayed onto the opening through the QR code nozzle 4012, thereby ensuring the clarity and quality of the inkjet printing on the opening. Furthermore, while spraying the coating onto the nozzle, the drive motor 305 rotates the clamped metal tube, ensuring uniform coating. The entire process is highly automated, easy to operate, and effectively improves the efficiency and accuracy of marking on metal tube nozzles.
