Description of the invention: [Technical field of invention] Jin and Γ Γ Γ 种 种 种 种 种 种 种 种 种 种 种 种 具有 具有 具有 具有 具有 具有 具有 具有 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏 魏Device and its screen version. , can be immediately [previous technology] because screen printing has shouting and resistance (four) characteristics of a variety of printing (four) on the printing, such as: _, _ products, broken glass in Tao Jing or India (four) road substrate, etc. Yumin New Industry. However, in the case of color printing, because the tension of the screen is uneven, the pressure is determined by the blade, which may result in inaccurate color registration, ink deposition, indirect printing resistance, or partial screen printing. Generally speaking, in response to the above problem, by sensing the screen version, it is possible to: to adjust the pressure under the bribe of the squeegee or to make the printing thickness to achieve a high feather requirement. Therefore, there are the following conventional sensing screen tension methods. Or the first conventional sensing screen tension method is an off-line type, which is performed on the screen of the printing device without performing a printing operation, and the H-manpower-tension meter is sequentially placed in several positions of the screen. To sense the tension she placed on the screen. However, Cai (4) puts the force meter in the manual version, so the cost of the _ over-the-counter is high, and the problem of sluggishness and low precision often associated with manual work cannot be ruled out. Moreover, this method cannot (4) feel the tension during brushing, and adjust or replace the information required for the screen. 201223776 The second conventional sensing screen tension method is an indirect line sensing method. The following is a method of "Screen printing method including printing pressure regulation" in the US Patent Publication No. 5052291. Please refer to FIG. It discloses a conventional printing device 9 that can sense the tension of the screen. The conventional printing device 9 is provided with a printing platform 91. Four sets of pressure sensors 92 are provided at four corners of the printing platform 91. The printing unit 9 further has a screen 93 and a printing blade 94 which is located between the printing platform 91 and the printing blade 94. Before the screen printing or the screen printing, the printing blade 94 presses the screen 93, and presses against the screen 93 and the pressure sensor 92, the printing blade 94 presses the pressure and the net The resultant force of the version 93 tension cancellation can be sensed by the pressure sensor 92, and the position of the pressure sensor 92 is calculated by the sensed value of the pressure sensor 92 and the pressure value printed under the knife 94. The screen version 93 tension. However, the conventional printing device 9 detects the resultant force of the pressing force of the printing blade 94 and the tension of the screen 93, and indirectly obtains the information of the tension of the screen 93, and the obtained tension of the screen 93 and the actual version of the screen 93 The error value between the tensions is large; in addition, the conventional printing t-setting 9 can only detect the tension of the screen 93 provided at the pressure sensor 92. If the pressure sensor is densely set, it cannot be obtained at the same time. The fine version 93 has a touch line force. 0, this method can not sense the tension of any position of the screen 9 3 in the same day, and the information for adjusting or replacing the screen 93 is slightly insufficient; if the pressure sensor is densely arranged, the problem of increasing the installation cost is increased. . Or, as in the Republic of China Patent Bulletin No. M342278, "Pressure-Resistant Scraper Her" new patent case, as shown in Figure 2, which reveals 201223776 a conventional printing device 8 that can adjust the tension of the screen, the conventional knowledge The printing device 8 is provided with a load cell 81, a pressure sensor 82, a printing blade 83 and a screen plate 84. The load cell 8 is provided with the pressure sensor 8 2 and connected to the printing blade 83'. The printing blade 83 faces the screen 84. When the load unit 81 is pressed down and the printing blade 83 abuts against the screen 84, the resultant force of the downward pressure of the printing blade 83 and the tension of the screen 84 can be obtained by the printing blade 83. The pressure sensor 82 is sensed by the sensed value of the pressure sensor 82 and the pressure value under the printing blade 83, and the screen 84 tension of the pressure sensor 82 is different. However, this method monitors the pressure at the printing blade 83 for indirect detection of the tension of the screen 84. Therefore, the tension of the screen 84 is transmitted to the pressure sensor η via the structure of the non-screen 84, and the error of the indirect sensing is obviously greater than the error value directly sensing the tension of the screen 84. For the above reasons, it is necessary to further improve the above-described conventional printing apparatus.

The screen of the present invention comprises: a printing surface formed on the surface of the screen, a pressing surface, relative to the printing surface, a printing area, # communicating the printing surface and the pressing surface; And at least the sensing member is disposed outside the printing area of the crucible. Thereby, when the screen printing is performed, the sensing member can instantly sense the tension of the screen for the user to use as a reference for replacing the screen. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The above and other objects, features and advantages of the present invention will become more apparent and understood. The "printing direction" described below is a printing blade moving direction for screen printing, which is familiar to those skilled in the art. Referring to Figures 3 and 4, it is a first embodiment of the present invention having a screen tension sensation W function. The printing device having the screen tension sensing function of the present invention comprises a platform 1, a screen 2 and a scraper 3, wherein the platform 1 is for placing a to-be-printed object 4, and the screen 2 is located at the platform 1 and the scraper 3, and the screen 2 has a function of sensing its tension. Thereby, when screen printing is performed, the doctor blade 3 is pressed against the screen 2 in a printing direction D, so that printing ink (printing Ink) is printed on the 201223776, and the tension can be sensed immediately for the user to use as a to-be-printed object. 4. This screen version 2 replaces the reference of the screen version 2. The plate 2 and the platform 1 are provided with a storage surface u facing the web scraper 3 for placing the object 4 to be printed. The job 2 is made of a net body printed by a conventional screen, which has a W-printing surface 2 - a pressing surface 22, a printing area 23 and at least a sensing member 24, and the printing surface 21 is formed. On one surface of the _ plate 2, the printing surface 21 is placed on the 丨 n of the platform 供, for the screen 2 to contact the to-be-printed 4. The facing surface 22 is formed on the printing surface 21 to form the other surface of the screen 2, and the pressing surface 22 faces the blade 3 for the von plate 2 to contact the δ-hai blade 3. The printing area 23 communicates with the printing surface 21 and the pressing surface 22 for the printing ink to penetrate from the pressing surface 22 to the printing surface 21 via the printing area 23, and the shape and range of the printing area 23 can be visually used. Adjusted for demand. In the present embodiment, the printing area 23 has a rectangular shape. The sensing member 24 is a component that can detect an object shape variable, such as a strain gauge or a film strain sensor. In this embodiment, the sensing member 24 is a thin film strain sensor. The sensing member 24 is disposed outside the printing area 23, and the sensing member 24 is disposed on the printing surface 21 or/and the pressing surface 22 according to the use requirement. In this embodiment, the sensing member 24 is disposed on the printing surface 21. The number of the sensing members 24 is set as needed, and one or several sensing members 24 are disposed adjacent to the edge of the printing region 23, or a plurality of sensing members 24 are disposed adjacent to the printing region along the printing direction D. 23 relative to the two edges. The sensing member 24 is configured to sense the tension of the screen 2, and the sensing member 24 is provided with a corresponding electrical change value of the wire output '201223776, such as a resistance value, a voltage value or a current value. Thereby, when screen printing is performed, the sensing member 24 can directly sense the shape variable of the screen 2, and the larger the value of the variable, the greater the tension of the screen 2, and vice versa. Referring to Figures 3 and 5, the scraper 3 is a conventional printing blade (Printing Squeegee) which faces the pressing surface 22 of the screen 2 and the storage surface 11 of the crucible 1, which can be used. The pressing surface 22 of the screen 2 is moved and moved in the printing direction d, so that the printing surface 21 of the screen 2 is in contact with the object 4 to be printed. • Refer to Figures 5 and 6 for a schematic view of the use of the printing apparatus having the screen tension sensing function of the present invention. When printing is to be performed, the printing ink is first placed on the pressing surface 22 of the screen 2, and the blade 3 is brought against the dust abutting surface 22 of the screen 2 to deform the screen 2 and contact the printing surface 21. The workpiece 4' is moved along the printing direction d, and the printing ink is squeezed from the pressing surface 22 into the printing area 23 of the screen 2, and penetrates to the printing surface 21' to place the printing ink on the printing To be printed 4. ¥5Hai scraper 3 slams down to the screen 2'. The sensor 24 can detect the position of the screen 2 shape variable, if the two sensing parts 24a and 24b are adjacent to each other The two opposite ends of the printing area 23, and the two ends of the blade 3 can pass over the two sensing members 24a and 24b (in terms of the 'surface'), and thus the two sensing members 24a and 24b The sensed value can be used to know whether the tension of the screen 2 at both ends of the scraper 3 is the same, and the user can evaluate whether the two ends of the scraper 3 are balanced as a reference for adjusting the scraper 3. Further, in order to make the shape variable of any position of the screen 2 can be sensed, the array sensing members 24a and 24b can be disposed along the printing direction D. In this embodiment, the feeling is The measuring units 24a and 24b are respectively disposed on two edge extension lines (L1 and L3) of the 201223776 printing area 23 and a central extension line ((2) of the printing area 23, wherein the two edge extension lines (1) and (3) and the center extension The line (L2) is parallel to the main knife 3. Further, since the sensing member 24 is directly attached to the screen 2, when the blade 3 presses the screen 2, the sensing member 24 is attached. The screen 2 is deformed to reduce the error caused by the variable of the _ version 2 being transmitted to the workpiece 24 indirectly through other structures. 凊 Referring to Figures 5, 6 and 7, if the blade 3 is The end system has been balanced'. When the blade 3 is pressed down to the edge of the printing area 23: when the line L1 is stretched, the sensing value of the sensing member 24 located on the edge extending line L1 is the largest, and the feeling is located at the center extending line L2. The sensing value of the measuring member 24 is second, and the sensing value of the sensing member 24 located at the edge extension line L3 is the smallest. For the same reason, please refer to the figures 8 , 9 and 10 It is shown that when the knives 3 are pressed down to the center of the printing area μ, the sensing value of the sensing member 24 located at the center extending line L2 is the largest at the line L2, and the sensing is located at the edge extending lines u and L3. The sensing value of the piece is next. As shown in Figures 1 and 12, when the blade 3 is pressed against the edge extension line L3 of the printing area 23, the sensing value of each position can be deduced by analogy. Therefore, the deformation position of the screen 2 and the distance between the sensing members 24 are inversely proportional to the value of each of the sheets, and the degree of deformation and the sense of any position of the plate making 2 The sensed value of the measuring piece 24 is proportional to the deformation of the screen 2 caused by the scraper 3, and the screen can be obtained by (4) the sensing value of the sensing member 24 of the different positions of the screen 2 The tension value of each position is case I. Please refer to Figure 14 for setting a preset tension value and displaying the sense. 10 - 201223776 Adjusting or replacing the network ~ ▼ 科月弟常法例 can be set separately - interface The wire of the sensing member 24 is molded.
