[0002] Screen printing technology is a common printing process that can be used to print a variety of materials such as screens and foam materials on the surfaces of various objects. The main process is to use a screen scraper to squeeze ink and other materials through the mesh holes on the screen printing plate and imprint them onto the substrate.

[0003] Conventionally, when printing conductive ink on silicone keys, the printing is simply performed, and the conductivity of the printed conductive ink needs to be manually tested later. It is impossible to timely determine whether the printing is too thick, resulting in insufficient conductivity, which easily causes batch products to be unqualified and causes waste.

[0004] Therefore need to propose a kind of new scheme to supplement the existing screen scraper. Utility Model Content

[0011] Preferably, the resistance meter is fixedly connected to an observation screen.

[0012] Compared with the prior art, the beneficial effect of the utility model is as follows: by installing the product on the screen printing machine, and then adjusting the position of the conductive wire according to the specifications of the goods, by sliding the detection end of the positive wire and the detection end of the negative wire to the two ends of the required detection position respectively, the limit rod is rotated at this time so that the limit rod presses the surface of the guide rail to apply a resistance force thereto, so that a strong resistance pressure is generated between the sliding part and the guide rail, thereby making the sliding part not easy to move, and after the adjustment is completed, the screen printing machine can be turned on to print the conductive ink, and when the screen scraper presses the conductive ink into the mesh, the conductive wire contacts the conductive ink printed in the mesh to perform resistance detection, and the conductive wire feeds back to the resistance meter, and the resistance meter displays the read data and makes a line graph to be displayed on the observation screen, so that the workers can observe and record in real time, so as to achieve the effect of real-time quality inspection, and problems can be discovered in time, thus avoiding batch goods from being unqualified due to failure to discover in time.

[0016] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0017] like Figure 1 , Figure 2As shown, a screen scraper with resistance detection includes a plate body 1, a conductive wire 2 is slidably arranged on the plate body 1, and an ohmmeter 3 is installed on the handheld part of the plate body 1, and both ends of the ohmmeter 3 are electrically connected to the conductive wire 2. By arranging the conductive wire 2 on the plate body 1, when the screen scraper presses the conductive ink into the mesh, the conductive wire 2 contacts the paint in the mesh to perform resistance detection, and the conductive wire 2 feeds back to the ohmmeter 3, so that the ohmmeter 3 reads and displays the detected data, so that the workers can observe and record, thereby achieving the effect of real-time quality inspection.

[0018] like Figure 1 , Figure 2 As shown, the conductive wire 2 includes a positive electrode wire 4 and a negative electrode wire 5. The detection end 6 of the positive electrode wire 4 and the needle detection end 6 of the negative electrode are flush with the contact end of the board body 1. The resistance is detected by the cooperation of the positive electrode wire 4 and the negative electrode wire 5. The positive electrode wire 4 and the negative electrode wire 5 are respectively placed at the two ends required for detection to simulate the contact between the circuit board and the conductive ink to ensure the resistance value. The detection end 6 of the positive electrode and the detection end 6 of the negative electrode wire 5 are flush with the contact end of the board body 1, so that when the contact end of the board body 1 contacts the screen printing plate and presses the conductive ink into the mesh, the detection end 6 of the positive electrode wire 4 and the detection end 6 of the negative electrode wire 5 contact and pass through the conductive ink in the mesh again, ensuring the accuracy of the detection and avoiding the thickness change during the printing process affecting the resistance value.

[0019] like Figure 1 , Figure 2 As shown, a sliding assembly for adjusting the position of the conductive wire 2 is provided between the board body 1 and the conductive wire 2, and the sliding assembly includes a slide rail 7 fixedly connected to the board body 1 and a slide member 8 detachably connected to the conductive wire 2, and the slide rail 7 is slidably connected to the slide member 8. By providing the sliding assembly, the position of the conductive wire 2 can be adjusted so as to be suitable for goods of different widths, and the adjustment is simple and easy through the cooperation of the guide rail and the slide member 8.

[0020] like Figure 1 , Figure 2 As shown, a positioning hole 9 is provided on the sliding member 8, and a limiting rod 10 for limiting the sliding member 8 is threadedly connected to the positioning hole 9. One end of the limiting rod 10 can abut against the guide rail. The positioning hole 9 is provided on the sliding member 8 so that workers can use the matching limiting rod 10 to limit the matching sliding member 8 in a single manner, so that the position of the sliding member 8 is fixed to avoid movement during use. The limiting rod 10 is placed in the positioning hole 9 with one end exposed to the surface of the sliding member 8 for the convenience of workers to hold and rotate it, and the other end abuts against the guide rail. The worker screws in the limiting rod 10 to make the limiting rod 10 abut against the guide rail, thereby generating a resistance pressure between the sliding member 8 and the guide rail, thereby preventing the sliding member 8 from being easily displaced.

[0021] like Figure 1 , Figure 2As shown, the resistance meter 3 is fixedly connected to an observation screen 11, and the data recorded by the resistance meter 3 is displayed in the form of a line graph through the observation screen 11, so that workers can have a more intuitive feeling when observing.

[0022] When this product is in use, the worker installs the product on the screen printing machine, and then adjusts the position of the conductive wire 2 according to the specifications of the goods, and slides the detection end 6 of the positive wire 4 and the detection end 6 of the negative wire 5 to the two ends of the required detection position respectively. At this time, the limit rod 10 is rotated so that the limit rod 10 presses against the surface of the guide rail to apply a resistance force to it, so that a strong resistance pressure is generated between the sliding member 8 and the guide rail, so that the sliding member 8 is not easy to move. After the adjustment is completed, the screen printing machine can be turned on to print the conductive ink. After the screen scraper presses the conductive ink into the mesh, the conductive wire 2 contacts the conductive ink printed in the mesh to perform resistance detection. The conductive wire 2 feeds back to the resistance meter 3, and the resistance meter 3 displays the read data and makes a line graph on the observation screen 11 for display, which is convenient for workers to observe and record in real time, so as to achieve the effect of real-time quality inspection, and can find problems in time, avoiding batch goods from being unqualified due to failure to find them in time.
