Description

Technical Field

[0001] The utility model relates to the technical field of screen printing, in particular to a screen printing machine head vibration monitoring device. Background Art

[0002] In the process of reducing costs and improving efficiency in the screen segment, the costs of screens and slurry account for a very high proportion. However, during the screen printing process, the print head sometimes shakes, resulting in uneven force on the screen during the downward pressure of the scraper, causing the screen to burst, resulting in a shorter screen life, increased slurry loss, and reduced production capacity.

[0003] Therefore, there is an urgent need to solve the problem of screen explosion caused by uneven force on the screen during the downward pressure of the scraper due to abnormal level of the printing head. Utility Model Content

[0008] An electronic level is located on the upper surface of the mounting head, and a clamping mechanism for clamping the electronic level in the center is provided on the mounting head.

[0009] Preferably, the clamping mechanism includes a C-shaped plate fixedly connected to the upper end of the mounting head, a bidirectional lead screw is rotatably connected between the inner side walls of the C-shaped plate, two clamps are threadedly connected to the side walls of the bidirectional lead screw, and the side walls of the clamps are in contact with the side walls of the electronic level.

[0012] The utility model has the following beneficial effects:

[0013] 1. Set up an electronic level. When the level of the screen printing head is abnormal, the electronic level will tilt due to the tilt of the screen printing head.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 2 A screen printing head vibration monitoring device includes two screen printing head bodies 1 and a fixed frame 2. Two electric guide rails 3 are fixedly connected to the inner wall of the fixed frame 2. Slide blocks 4 are installed on the two electric guide rails 3. Four mounting plates 5 are fixedly connected to the lower end of the slide block 4. A mounting head 6 is fixedly connected between two mounting plates 5 close to each other. The lower end of the mounting head 6 is fixedly connected to one of the screen printing head bodies 1. The installation of the screen printing head body 1 is based on existing mature technologies.

[0020] The electronic level 7 is located on the upper surface of the mounting head 6. It should be noted that the electronic level 7 is connected to the external machine computer through a transmission line, and there is a program for monitoring the electronic level inside the computer. When the level of the screen printing head body 1 is abnormal, the electronic level 7 tilts due to the tilt of the screen printing head body 1. When the voltage change of the induction coil caused by the movement of the internal pendulum of the electronic level 7 exceeds the set range, the machine computer automatically alarms and stops printing. Subsequently, the production staff confirms that there is no abnormality in the level of the printing head and then resumes production. The induction alarm control method is a prior art and will not be elaborated here. It can avoid screen explosion caused by head level problems, thereby increasing the service life of the screen. In addition, since there is no screen explosion caused by print head level problems, the increase in slurry loss and the loss of production capacity are avoided.

[0021] The mounting head 6 is provided with a clamping mechanism for centering the electronic level 7, and the clamping mechanism includes a C-shaped plate 8 fixedly connected to the upper end of the mounting head 6, a bidirectional lead screw 11 is rotatably connected between the inner side walls of the C-shaped plate 8, and two clamping plates 10 are threadedly connected to the side walls of the bidirectional lead screw 11, and the side walls of the clamping plates 10 are fitted with the side walls of the electronic level 7, and a plurality of sliding rods 9 are fixedly connected between the inner side walls of the C-shaped plate 8, and the side walls of the plurality of sliding rods 9 are all slidably connected to the side walls of the two clamping plates 10.

[0022] Furthermore, in order to ensure the center clamping of the electronic level 7, the two clamping plates 10 are brought closer to each other by rotating the bidirectional screw 11, so that the electronic level 7 can be center clamped, so that when there is an abnormality in the level of the screen printing head body 1, the electronic level 7 can be tilted in the first time due to the tilt of the screen printing head body 1.

[0023] One end of the bidirectional lead screw 11 passes through the side wall of the C-shaped plate 8 and is fixedly connected to a handle 12. The side wall of the bidirectional lead screw 11 outside the C-shaped plate 8 is threadedly connected to a nut 13. The side wall of the nut 13 fits with the side wall of the C-shaped plate 8, which can limit the rotation position of the bidirectional lead screw 11 and ensure the firmness of the clamping of the electronic level 7.

[0024] When installing the electronic level 7 on the screen printing head body 1, first place the electronic level 7 on the upper surface of the installation head 6, and the electronic level 7 is located between the two clamping plates 10, then rotate the handle 12 clockwise to drive the bidirectional lead screw 11 to rotate clockwise, so that the two clamping plates 10 are close to each other to clamp the electronic level 7 in the center, so that when the level of the screen printing head body 1 is abnormal, the electronic level 7 can be tilted due to the tilt of the screen printing head body 1 at the first time, and then rotate the nut 13 so that the side wall of the nut 13 is closely fitted with the side wall of the shaped plate 8, and the rotation position of the bidirectional lead screw 11 is limited to ensure the clamping firmness of the electronic level 7;

[0025] During the subsequent use of the screen printing head body 1, when the level of the screen printing head body 1 is abnormal, the electronic level 7 tilts due to the tilt of the screen printing head body 1. After the voltage change of the induction coil caused by the movement of the internal pendulum of the electronic level 7 exceeds the set range, the machine computer automatically alarms and stops printing. Subsequently, the production staff confirms that there is no abnormality in the level of the printing head and then resumes production. The induction alarm control method is a prior art and will not be elaborated here. It can avoid screen explosion caused by head level problems, thereby increasing the service life of the screen. In addition, since there is no screen explosion caused by print head level problems, the increase in slurry loss and the loss of production capacity are avoided.

[0026] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
