Description

Technical Field

[0001] The present application relates to the technical field of printing equipment, and in particular to a character screen printer. Background Art

[0002] A character screen printer is a device specifically used to print characters, symbols or patterns on the surface of various materials. It is often used in industrial and commercial applications that require precise and durable marking on products.

[0003] In the printing industry, traditional printing methods often use manual scraping of ink, but this method is not only inefficient, but also difficult to ensure accuracy, and cannot meet the high requirements of modern industrial production for printing quality and efficiency. At present, there are some automated printing equipment on the market, which use electric or pneumatic methods to drive the scraper for printing. However, these devices still have many deficiencies in structural design and control accuracy. For example, the setting position adjustment between the screen and the working plate is not accurate enough, which easily leads to the production of defective printed products.

[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0005] The purpose of this application is to improve the accuracy and efficiency of printing materials.

[0006] The above technical purpose of the present application is achieved through the following technical solutions: a character screen printing machine, including a workbench for setting a work plate; a mounting frame is provided on the workbench, a vertical lifting member is provided on the mounting frame, a screen frame is provided on the vertical lifting member, and the vertical lifting member drives the screen frame to move toward or away from the workbench; a silk screen is provided on the screen frame, and the screen frame and the silk screen are surrounded to form an interlocking groove for interlocking the work plate; a horizontal moving member is also provided on the vertical lifting member, a scraper is provided on the horizontal moving member, and the horizontal moving member drives the scraper to move on the silk screen.

[0007] By adopting the above technical solutions, precise control can ensure that the screen frame and scraper are always in the best position during the printing process. The height of the screen frame can be controlled by the vertical lifting member to ensure that the distance between the screen and the working plate is always consistent, thereby avoiding printing errors caused by height changes. The horizontal moving member can accurately control the movement of the scraper on the screen, so that the ink is evenly distributed on the working plate, further improving the accuracy and consistency of printing. The meshing groove formed by the screen frame and the screen is used to accurately fit the working plate. The stability of each component during the printing process is greatly enhanced, and printing defects caused by component displacement or instability are avoided. Through these precise positioning mechanisms, repeatability and reliability are ensured during each printing process, thereby improving the overall operational stability. The use of automated vertical lifting and horizontal movement mechanisms enables the character screen printer to complete multi-step printing operations quickly and accurately. The automated drive device not only reduces the time and error of manual operation, but also makes the entire printing process smoother and more efficient. By reducing manual intervention and improving the level of automation, production efficiency is significantly improved, making the device particularly suitable for large-scale, high-precision character printing applications.

[0008] Optionally, the workbench is provided with a plurality of first positioning pins for positioning the work plate.

[0009] By adopting the above technical solution, the first positioning pin is used to accurately locate the position of the working plate, ensuring that the working plate is in the same position each time printing. This precise positioning effectively reduces the positional deviation of the working plate during the printing process, thereby ensuring the accuracy and consistency of the printed pattern and characters. For applications that require high-precision printing, such as electronic components, precision instrument panels, etc., the printing quality can be significantly improved. By setting a number of first positioning pins on the workbench, the operator only needs to place the working plate in a fixed position to start printing, reducing the time for alignment and debugging. This design greatly simplifies the operating process, reduces the requirements for the operator's skill level, and improves production efficiency. Fast and accurate positioning reduces the complexity of manual operation and makes the equipment easier to use. The first positioning pin can not only accurately locate the working plate, but also maintain its stability during the printing process to prevent the working plate from moving or vibrating during the printing process. This stability is crucial to ensuring printing quality, especially when multiple printings or long-term continuous printing. The stable support of the positioning pin ensures the quality consistency of each batch of printed products and reduces the defective rate.

[0010] Optionally, the screen frame is provided with a plurality of second positioning pins, and the workbench is provided with positioning grooves corresponding to the positions of the second positioning pins, and the second positioning pins and the positioning grooves are fitted and engaged with each other.

[0011] By adopting the above technical solution, the matching and embedded design of the second positioning pin and the positioning groove ensures the precise alignment between the screen frame and the workbench. Each time the screen frame is installed, these positioning pins and positioning grooves can be used to achieve quick and precise alignment, avoiding the position deviation of the screen frame in different printing operations. This precise positioning mechanism ensures that the characters and patterns printed each time are in the same position, thereby greatly improving the accuracy and consistency of printing. The screen frame and the workbench are tightly matched and embedded through the second positioning pin and the positioning groove to ensure the stability of the screen frame during the printing process. It effectively prevents the displacement of the screen frame due to vibration or other external forces, ensuring the smooth progress of the printing process and the stability of the printing effect. This design is particularly suitable for applications with long-term continuous printing and high-precision requirements, reducing the defective rate and printing defects.

[0012] Optionally, the screen frame and the screen together form a receiving groove for receiving ink.

[0013] By adopting the above technical solution, the receiving groove formed by the screen frame and the screen can effectively hold the ink, so that the ink is concentrated in one area, and at the same time, the scraper is limited to prevent the scraper from exceeding the setting range of the screen. The waste of ink is avoided and the ink can be evenly distributed on the screen. By reducing the waste of ink, the utilization efficiency of ink is improved and the production cost is reduced.

[0014] Optionally, the vertical lifting member includes a first slide rail, a first slider is provided on the first slide rail, the first slider is connected to a first driving member, and the first driving member drives the first slider to slide on the first slide rail toward or away from the working plate.

[0015] By adopting the above technical solution, the controllable sliding property of the vertical lifting member makes it possible to accurately adjust the distance between the screen and the working plate during the printing process. By sliding the first slider on the first slide rail, the operator can easily adjust the distance between the screen and the working plate to ensure appropriate printing pressure and printing accuracy. This precise control can improve the clarity and consistency of characters and patterns during the printing process, thereby improving the quality of the product.

[0016] Optionally, a clamping piece is provided on the first sliding block for clamping the screen frame.

[0017] By adopting the above technical solution, the presence of the clamp ensures the stability of the screen frame during the printing process. By clamping the screen frame, it can be effectively prevented from loosening or shifting during the printing process, thereby maintaining the stability and consistency of the printing process. The stable screen frame position helps to maintain a constant distance and pressure between the screen and the working plate, thereby ensuring the quality and consistency of the printing effect. The design of the clamp makes it easier and more convenient to install and replace the screen frame. The operator only needs to place the screen frame on the clamp and fix it on the first slider without additional tools or complicated operating steps. This design greatly reduces the complexity and time cost of the operation, improves the convenience and efficiency of the operation, and makes the equipment easier to operate and maintain.

[0018] Optionally, the horizontal moving member includes a second slide rail arranged on the first slide block, the second slide rail is provided with a second slide block, the second slide block is connected to a second driving member, and the second slide block is driven to move on the second slide rail by the second driving member, and the scraper is arranged on the second slide block.

[0019] By adopting the above technical solution, the design of the horizontal moving member can ensure that the movement of the scraper on the screen is smooth and uniform. By moving the second slider on the second slide rail, the position and movement trajectory of the scraper can be controlled to ensure the uniform distribution of ink on the screen. Such a design helps to improve printing quality and consistency, ensuring that each printed product has the same printing effect. The design of the horizontal moving member makes the position adjustment of the scraper more flexible and convenient. By controlling the movement of the second slider through the second driving member, the operator can easily adjust the position of the scraper on the screen to meet different printing requirements. This flexible adjustment function improves the convenience and flexibility of operation, making the equipment more suitable for different printing application scenarios.

[0020] Optionally, the scraper is made of elastic material.

[0021] By adopting the above technical solution, the scraper is made of elastic material, which can better adapt to the unevenness of the screen surface, ensuring that the ink can be evenly scraped and distributed on the working plate when the scraper moves. The characteristics of this elastic material make the contact between the scraper and the screen closer, so as to more effectively control the distribution of ink and improve the printing quality. The elastic scraper can reduce the wear of the screen. Compared with the hard scraper, the elastic scraper has less friction on the screen, which reduces the wear and damage to the screen surface and prolongs the service life of the screen. This helps to reduce the maintenance cost of the equipment and improve production efficiency.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. Precise control ensures that the screen frame and scraper are always in the best position during the printing process. The height of the screen frame is controlled by the vertical lifting member, which ensures that the distance between the screen and the working plate is always consistent, thus avoiding printing errors caused by height changes. The horizontal moving member can accurately control the movement of the scraper on the screen, so that the ink is evenly distributed on the working plate, further improving the accuracy and consistency of printing. The meshing groove formed by the screen frame and the screen is used to accurately fit the working plate. The stability of each component during the printing process is greatly enhanced, and printing defects caused by component displacement or instability are avoided. Through these precise positioning mechanisms, repeatability and reliability are ensured during each printing process, thereby improving the overall operational stability. The use of automated vertical lifting and horizontal movement mechanisms enables the character screen printer to complete multi-step printing operations quickly and accurately. The automated drive device not only reduces the time and error of manual operation, but also makes the entire printing process smoother and more efficient. By reducing manual intervention and improving the level of automation, production efficiency is significantly improved, making the equipment particularly suitable for large-scale, high-precision character printing applications.

[0024] 2. The function of the first positioning pin is to accurately locate the position of the work plate, ensuring that the work plate is in the same position each time it is printed. This precise positioning effectively reduces the positional deviation of the work plate during the printing process, thereby ensuring the accuracy and consistency of the printed patterns and characters. For applications that require high-precision printing, such as electronic components, precision instrument panels, etc., it can significantly improve the printing quality. By setting a number of first positioning pins on the workbench, the operator only needs to place the work plate in a fixed position to start printing, reducing the time for alignment and debugging. This design greatly simplifies the operation process, reduces the requirements for the operator's skill level, and improves production efficiency. Fast and accurate positioning reduces the complexity of manual operation and makes the equipment easier to use. The first positioning pin can not only accurately locate the work plate, but also maintain its stability during the printing process to prevent the work plate from moving or vibrating during the printing process. This stability is essential to ensure printing quality, especially when multiple printings or long-term continuous printing. The stable support of the positioning pin ensures the quality consistency of each batch of printed products and reduces the defective rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] In this embodiment, refer to Figure 1-2 A character screen printer comprises a workbench 1, a mounting frame 3, a vertical lifting member 4, a screen frame 5, a screen 6, a horizontal moving member 8 and a scraper 9. The workbench 1 is used to stably set a working plate 2, and its upper surface is flat to ensure the stability of the working plate 2 during the printing process. The mounting frame 3 is fixedly arranged on the workbench 1 to provide a stable support structure. The vertical lifting member 4 is installed on the mounting frame 3, and can drive the screen frame 5 to move up and down. The screen frame 5 is fixed on the vertical lifting member 4, and a screen 6 is stretched inside it. An interlocking groove 7 is formed between the screen 6 and the screen frame 5, which is used to accurately engage the working plate 2 to ensure the accuracy of the printing position. The horizontal moving member 8 is installed on the vertical lifting member 4, and moves the scraper 9 in the horizontal direction, and the scraper 9 moves close to the surface of the screen 6 to achieve uniform printing.

[0031] The implementation principle of this embodiment is as follows: after placing the work plate 2 to be printed on the workbench 1, the height of the screen frame 5 is adjusted by the vertical lifting member 4, and the screen frame 5 is engaged with the work plate 2 through the engaging groove 7, so that the screen frame 5 just abuts against the workbench 1, so that the screen 6 on the screen frame 5 is closely fitted with the upper surface of the work plate 2. Subsequently, the worker pours ink onto the screen 6, and the horizontal moving member 8 is started, driving the scraper 9 to move horizontally on the screen 6, and the scraper 9 evenly scrapes the ink on the screen 6 onto the work plate 2 to complete the printing process. Due to the precise control of the vertical lifting member 4 and the horizontal moving member 8, the character screen printer of this application can achieve high-quality and high-efficiency printing operations.

[0032] In this embodiment, refer to Figure 1 and Figure 2 The screen frame 5 and the screen 6 are surrounded by a receiving groove 13 for receiving ink. The movement path of the scraper 9 is prevented from exceeding the set length of the screen 6, thereby reducing the possibility of ink loss. Figure 1 The scraper 9 is preferably made of an elastic material, such as rubber or elastic plastic, etc. This material has good elasticity and can be adaptively adjusted according to the shape of the screen 6, ensuring that the scraper 9 always maintains a close fit with the screen 6 during the printing process, thereby achieving a more uniform printing effect.

[0033] Example 2, reference Figure 1 The difference of this embodiment is that a plurality of first positioning pins 10 are additionally provided on the workbench 1. These first positioning pins 10 are distributed at predetermined positions of the workbench 1 and are used to accurately position the work plate 2. By matching the corresponding holes on the work plate 2 with the first positioning pins 10, it is possible to ensure that the work plate 2 is in the same accurate position each time it is placed, thereby further improving the repeatability accuracy of printing.

[0034] Example 3, reference Figure 1 On the basis of Embodiment 1 or 2, a plurality of second positioning pins 11 are added to the screen frame 5 of this embodiment, and positioning grooves 12 are provided on the workbench 1 at positions corresponding to the second positioning pins 11. When the screen frame 5 descends and contacts the workbench 1, the second positioning pins 11 will be accurately embedded in the corresponding positioning grooves 12, thereby achieving accurate positioning between the screen frame 5 and the workbench 1. This structure not only ensures that the screen frame 5 can be accurately aligned with the work plate 2 every time it descends, but also greatly improves the registration accuracy of printing.

[0035] Example 4, reference Figure 1 , the difference of this embodiment is that the specific structures of the vertical lifting member 4 and the horizontal moving member 8 are further refined. The vertical lifting member 4 includes a first slide rail 41 and a first slider 42. The first slider 42 is driven by a first driving member (such as an electric push rod or a cylinder) to slide up and down on the first slide rail 41, thereby driving the screen frame 5 to move up and down. The horizontal moving member 8 includes a second slide rail 81 and a second slider 82 arranged on the first slider 42. The second slider 82 is driven by a second driving member (such as a servo motor and a screw transmission mechanism) to slide horizontally on the second slide rail 81, thereby driving the scraper 9 to move accurately left and right to complete the printing action. A clamping member 14 is provided on the first slider 42 for clamping the screen frame 5. The existence of the clamping member 14 ensures the stability of the screen frame 5 during the printing process. By clamping the screen frame 5, it can be effectively prevented from loosening or shifting during the printing process, thereby maintaining the stability and consistency of the printing process. The stable position of the screen frame 5 helps to maintain a constant distance and pressure between the screen 6 and the working plate 2, thereby ensuring the quality and consistency of the printing effect. The design of the clamping member 14 makes it easier and more convenient to install and replace the screen frame 5. The operator only needs to place the screen frame 5 on the clamping member 14 to fix it on the first slider 42 without any additional tools or complicated operation steps. This design greatly reduces the complexity and time cost of the operation, improves the convenience and efficiency of the operation, and makes the equipment easier to operate and maintain.

[0036] Example 5, reference Figure 1Based on Example 4, this embodiment further adds a detailed description of the control system. The control system includes a central processing unit, a sensor, and an actuator. The central processing unit is responsible for receiving and processing the data collected by the sensor, and controlling the action of the actuator (i.e., the first drive member and the second drive member) according to the preset printing program. The sensor is used to monitor the position, speed and other parameters of the vertical lifting member 4 and the horizontal moving member 8 in real time, and feeds these data back to the central processing unit to ensure the accurate controllability of the printing process. Through the intelligent management of the control system, the character screen printer of the present application can realize fully automated printing operations, greatly improving production efficiency and product quality.

[0037] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
