[0002] With the explosive growth of global mobile data and the rapid development of other wireless communication and positioning methods such as the Global Positioning System (GPS), microwave dielectric ceramics, as a crucial dielectric material, can handle a variety of high-frequency signals and microwave signals, and are developing towards higher frequencies and greater signal tunability.

[0003] In today's big data era, the demands for thinner, lighter, higher-performance, and lower-loss electronic devices place higher requirements on microwave dielectric ceramic materials. However, current ceramic material processing has a large range of errors and irregular bottom shapes. For screen printing devices with fixed dimensions, small-sized devices cannot be fixed, while large-sized devices cannot be placed in the device for positioning. For problems such as uneven bottoms, each device needs to use a separate screen printing device, which is complex in terms of processing quantity and size and is not conducive to production. Therefore, existing screen printing devices cannot meet the requirements for automatic screen printing of various devices of different sizes. Utility Model Content

These embodiments are enumerated rather than exhaustive. Furthermore, for the sake of brevity, content mentioned in the preceding embodiments is often omitted in the following embodiments. Therefore, content not mentioned in the later embodiments can be referred to in the preceding embodiments.

[0013] Example 1

[0014] A centering screen printing device, such as Figure 1 As shown, it includes: base plate 1, centering crossbeam 7, centering crossbeam 8, pad block 6, baffle 2, baffle 3, slider 4, and top block 5;

[0015] The base plate 1 is a sheet structure and serves as the installation reference. A centering beam 7 and a centering beam 8 are installed in the middle of the base plate 1, dividing the base plate 1 into four parts. Baffles 2 and 3 are installed on the four sides of the base plate 1.

[0016] The centering beams 7 and 8 are provided with grooves, which serve as slides for the slider 4. The slider 4 slides in the grooves of the centering beams 7 and 8. A top block 5 is installed inside the slider 4 for positioning the slider 4.

[0017] A pad 6 is placed in the middle position enclosed by the base plate 1, the centering beam 7, and the centering beam 8 to support the chip and other irregularly shaped devices for screen printing.

[0018] As an optional implementation, the base plate 1 is provided with a rectangular groove structure for positioning and assembly with the centering beam 7 and the centering beam 8.

[0019] As an optional implementation, the rectangular groove structure of the base plate 1 is cross-shaped and located perpendicularly to each other in the middle of the base plate 1.

[0020] As an optional implementation, the centering beams 7 and 8 are cross-shaped centering results, and their sides are provided with grooves corresponding to the slider 4 for the movement of the slider 4.

[0021] As an optional implementation, the base plate 1 is fixed with screws to the centering beam 7 and the centering beam 8.

[0022] As an alternative implementation, the movement or fixation of slider 4 is adjusted by screws located on the slider.

[0023] As an optional implementation, the top block 5 of the slider 4 is provided with a retractable elastic device for fixing the screen printing device.

[0024] As an optional implementation, the pad 6 is adapted to the shape of the chip and is used to position the chip by cooperating with the slider 4 and the top block 5.

[0025] As an optional implementation, baffles 2 and 3 are strip-shaped and symmetrically arranged around the base plate, and are connected and fixed to the base plate 1 by screws.

[0026] As an optional implementation, the specifications of the centering beam 7, centering beam 8, and baffles 2 and 3 are determined according to the tooling dimensions of the screen printing machine.

[0027] Specifically, the aforementioned screen printing equipment, such as... Figure 1As shown, the screen printing device includes a base plate 1, a centering beam 7, a centering beam 8, four pads 6 of different or the same size, a clamping baffle 2, a baffle 3, a slider 4, and a top block 5. The base plate 1 is a sheet structure providing an overall mounting reference. Two types of centering beams 7 and 8 with grooves are installed in the middle of the base plate 1 to provide a sliding path for the slider 4 and divide the base plate 1 into four parts. Two types of baffles 2 and 3 for clamping are installed on the four sides of the base plate 1 to increase the rigidity of the thin base plate. An elastic top block 5 is installed inside the slider 4 to move and position with the slider 4. A chip pad 6 is placed in the middle of the four parts enclosed by the base plate 1, slider 5, and centering beams 7 and 8 to support the chip and other irregularly shaped devices for screen printing. The centering beams 7 and 8, and the clamping baffles 2 and 3 are installed above the base plate 1. The movement and fixation of the slider 4 are adjusted by loosening and tightening screws located on the slider 4.

[0028] The base plate 1 serves as the overall installation reference and positioning support, and is provided with mounting screw holes and mounting grooves for matching the centering beams 7 and 8. After the clamp baffles 2 and 3 are installed on the base plate 1 along with the centering beams 7 and 8, the rigidity of the entire device will be increased, effectively avoiding the problem of insufficient structural strength caused by a thin base plate.

[0029] The Z-axis force during the screen printing process is transmitted to the base plate 1 through two clamping baffles 2 and the centering beam 8, and then to the brushing device through the base plate 1 and the pad 6. After the clamping baffles 2 and 3 are connected to the base plate 1 with screws, the two are further connected with screws to improve the overall rigidity.

[0030] The base plate 1 is connected to the centering beams 7 and 8 with screws. The centering beams 7 and 8 are perpendicular to each other. After installation, the center of the centering beams 7 and 8 will also be the center of the entire device. The centering beams 7 and 8 will then serve as the installation reference for the screen printing device.

[0031] To further improve positioning accuracy, grooves are machined at the installation positions of the base plate 1 and the centering beams 7 and 8. The dimensions of the grooves match the dimensions of the centering beams 7 and 8, thereby improving positioning and installation accuracy.

[0032] After the centering beams 7 and 8 are installed on the base plate 1, their upper surfaces are flat and on the same plane. The side walls of the centering beams 7 and 8 are machined with grooves, and the sliders 4 are installed in the grooves. The sliders 4 can slide and be fixed inside the grooves. The sliders 4 are equipped with screws. When it needs to be moved, the slider screws can be adjusted to make it slide smoothly. When it is moved to the designated position, the slider screws can be adjusted back to the original position to fix the sliders 4, which plays a positioning role.

[0033] The sliding grooves of the centering beams 7 and 8 are set with T-slots, which are easy to process and the processing cost of the matching sliders 4 is also reduced. The tolerance between the T-slots and the sliders adopts clearance fit. The sliders are fixed by using screws to clamp the structural walls on both sides of the T-slots, instead of using screws to install inside the T-slots, which would damage the integrity and smoothness of the inner wall of the sliding groove.

[0034] Each slider 4 is also equipped with an elastic top block 5, and the two are connected by an interference fit. The elastic top block 5 has a limiting device to prevent it from sliding out when subjected to force. Figure 2 As shown, the elastic top block 5 consists of a top block 9, an elastic pin 11, and an assembly screw 10. It features an elastic adjustment device, which can position the component even when the dimensional tolerance of a single component is large, effectively preventing improper installation or failure to secure the component.

[0035] The mounting screws 10 and the top block 9 on the elastic top block 5 have been redesigned according to the special requirements of the printing device, further improving the adaptability of special types of devices and enhancing the universality of the printing device.

[0036] The pad 6 is a square pad, smaller than the printed component, which serves to elevate the component and make it protrude from the upper surface of the centering beam 7 and centering beam 8. Only one pad 6 is placed in the figure, and a maximum of four pads can be screen printed simultaneously, without limitation on the number of pads to be added or removed according to actual needs.

[0037] The pad 6 is designed independently according to the bottom shape of the printed device; the pad 6 must be smaller than the actual size of the printed device to ensure that the device can be fixed by the elastic top block 5; the pad 6 also adjusts the surface of the printed solder plane to be flush with the stencil according to the shape of the printed device to prevent the solder printing from being crooked or the solder from sticking together.

[0038] The countersunk screws used in this example are all of the same size, but in actual implementation, they can be replaced with head screws and other screws according to the actual situation; this screen printing device can change the number of simultaneous printing according to the needs, and supports printing up to 4 devices simultaneously.

[0039] The thickness between the centering beams 7 and 8 and the base plate 1 is determined according to the maximum or optimal size of the actual screen printing machine. The machine clamp baffles 2 and 3 shall not be higher than the centering beams 7 and 8. After the pad 6 is installed, the surface of the printed device must protrude from the surface of the centering beams 7 and 8.

[0040] The base plate 1 may have holes made for special components that may appear in the actual situation to further increase its applicability or eliminate processing stress.
