[0041] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0042] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0043] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0044] Currently, most screen printing methods use a fixed light source to cure the screen-printed product. However, this makes it difficult to guarantee product quality during the curing process, affecting the product's aesthetics and functionality. To address this issue, the design of this invention involves making the screen printing light source movable. The optimal installation position of the light source is determined by an ink scanning device, and the light source is moved to this optimal position to ensure product quality.

[0045] Based on the above design concept, the adjustable light source fixing device proposed in this utility model includes a light source fixing bracket 1, a fixing rod 2 for installing the light source fixing bracket 1 on the screen printing machine, and a support mechanism provided on the light source fixing bracket 1.

[0046] The aforementioned support mechanism is used to install the screen printing light source 3 and can adjust the installation height and horizontal position of the screen printing light source 3.

[0047] In addition, the present invention is provided with an ink scanning device 4 on the support mechanism. The ink scanning device 4 can determine the optimal installation position of the screen printing light source 3 according to the ink distribution of the object to be screen printed. The support mechanism can adjust the screen printing light source 3 to move to the optimal installation position.

[0048] Based on the above settings, the working principle of this utility model is as follows: after the object to be screen-printed enters the screen-printing position, the ink scanning device 4 scans the ink distribution on the object to be screen-printed, and determines the optimal installation position of the screen-printing light source 3 based on the scanning results. Then, the screen-printing light source 3 is adjusted to move to the optimal installation position, thereby ensuring the curing effect of the screen-printing light source 3 on the object to be screen-printed.

[0049] The scheme for determining the optimal installation position of the screen printing light source 3 by the ink scanning device 4 can be pre-planned in the memory of the ink scanning device 4. It first obtains the correspondence between ink distribution and optimal installation position through multiple experimental simulations and stores it in the memory of the ink scanning device 4. After obtaining the ink distribution through the ink scanning device 4, the optimal installation position can be determined based on the pre-stored relevant data.

[0050] It should be noted that the distribution of the screen printing light source 3 in terms of horizontal position and installation height is countless. Therefore, when storing the above-mentioned relevant data, corresponding intervals can be set for storage, such as the interval in which the ink characteristics are located and the interval in which the optimal installation position is located. The minimum unit division of the specific interval can be set according to the required precision. This can reduce the amount of data storage while ensuring that the optimal installation position is obtained.

[0051] Furthermore, the position adjustment of the screen printing light source 3 can be done automatically or manually. In manual mode, the optimal installation position can be determined directly through the settings described above. When using automatic adjustment, additional drivers and controllers are needed, such as a PLC system. This PLC system needs to be connected to the ink scanning device 4. After the ink scanning device 4 determines the optimal installation position, it can directly transmit relevant information to the PLC system for control. The PLC system then adjusts the position of the screen printing light source 3 through the relevant drivers. Under this setup, the data relating the ink distribution to the optimal installation position can be directly stored in the PLC system. This way, the ink scanning device 4 only needs to determine the specific ink distribution and send it to the PLC system, reducing the storage space required for the ink scanning device 4.

[0052] As can be seen from the above settings, the ink scanning device 4 and related support mechanisms in this utility model enable the screen printing light source 3 to move to the optimal installation position, ensuring product quality under different screen printing light source requirements and improving the product's aesthetics and functionality.

[0053] Please see Figures 1 to 4 The specific configuration of the support mechanism in this utility model is as follows:

[0054] The support mechanism includes at least two pairs of support columns 5 disposed on the light source fixing bracket 1, a crossbar 6 located between each pair of support columns 5 and both ends of which are mounted on the support columns 5, and at least one sliding rod 7 connecting all the crossbars 6.

[0055] The crossbar 6 can move along the direction of the slide bar 7, and the height of the crossbar 6 mounted on the support column 5 at both ends is adjustable;

[0056] The screen printing light source 3 is mounted on the slide bar 7.

[0057] Here, the main purpose of setting the crossbar 6 is to realize the longitudinal movement of the screen printing light source 3 (that is, to move along the setting direction of the crossbar 6). As can be seen from the above setting, since the screen printing light source 3 is mounted on the slide bar 7, the screen printing light source 3 will also move synchronously when the slide bar 7 moves. Since the slide bar 7 is connected to all the crossbars 6, the slide bar 7 can only move along the setting direction of the crossbar 6. That is, the setting of the crossbar 6 realizes the longitudinal movement of the screen printing light source 3.

[0058] Meanwhile, since the height of the two ends of the crossbar 6 is adjustable on the support column 5, and the slide bar 7 is assembled on the crossbar 6, when the installation height of the crossbar 6 changes, the height of the slide bar 7 will also change. At the same time, the change in the height of the slide bar 7 will also cause the height of the screen printing light source 3 to change. That is, the adjustable height of the two ends of the crossbar 6 realizes the height adjustment of the screen printing light source 3.

[0059] In summary, the combined arrangement of the crossbar 6 and slide bar 7 in this utility model enables adjustment of the installation height and longitudinal position of the screen printing light source 3.

[0060] In addition, in order to achieve all-round adjustment of the screen printing light source 3, horizontal adjustment is also required on the horizontal plane. In this utility model, the screen printing light source 3 is installed on the slide rod 7 in a hanging manner, and the hanging position of the screen printing light source 3 can be adjusted.

[0061] Please see Figure 1 Two round holes are provided on both ends of the screen printing light source 3, and the slide rod 7 passes through these two round holes respectively to support the screen printing light source 3. Due to the round holes, the screen printing light source 3 can use the slide rod 7 as a guide rail and move on the guide rail. Therefore, the screen printing light source 3 can realize the movement in the direction of the slide rod 7. Here, the direction of the slide rod 7 is perpendicular to the horizontal bar 6. The direction of the horizontal bar 6 is set vertically, and the direction of the slide rod 7 is set horizontally. That is, in this utility model, the horizontal position of the screen printing light source 3 is adjusted through this part.

[0062] Based on the above configuration of the crossbar 6, slide bar 7, and screen printing light source 3, it is clear that this utility model achieves adjustment in the longitudinal direction, the transverse direction, and the installation height, that is, it achieves all-round adjustment of the screen printing light source 3.

[0063] The above-described arrangement of multiple crossbars 6 is an embodiment of this utility model; please refer to [link / reference]. Figure 1 Figure 4 In a preferred embodiment of this utility model, two pairs of support columns 5 are provided. Since the crossbars 6 are arranged between each pair of support columns 5, there are also two pairs of corresponding crossbars 6. Figure 1 It is quite obvious that each pair of support columns 5 has two support columns 5, and the line connecting the four support columns 5 forms a rectangle. With this arrangement, the position of the crossbar 6 is equivalent to the width of the rectangle, which means that the two crossbars 6 must be parallel to each other.

[0064] Similarly, in this utility model, both ends of the slide bar 7 are mounted on the crossbar 6, and the setting direction of the slide bar 7 is perpendicular to the setting direction of the crossbar 6.

[0065] Compared to the previous setup that did not specify the direction of the crossbar 6 and the slider 7, this setup can more directly determine the movement direction of the screen printing light source 3. Compared to the crossbar 6 crossing setup (such as when the line connecting the four support columns 5 is not trapezoidal), it is easier to realize the movement of the slider 7 on the crossbar 6.

[0066] Furthermore, the present invention provides first mounting parts 8 at both ends of the crossbar 6 and second mounting parts 9 at both ends of the slide bar 7;

[0067] Both the first mounting component 8 and the second mounting component 9 are movable structures.

[0068] Please see Figure 1 In this utility model, the first mounting part 8 is essentially used to assemble the crossbar 6 onto the support column 5, and the second mounting part 9 is essentially used to assemble the sliding rod 7 onto the crossbar 6. The structure of the first mounting part 8 and the second mounting part 9 can be set as a clamping structure, a snap-fit ​​structure, etc., as long as it can ensure that after the first mounting part 8 is installed, the positions of the two ends of the crossbar 6 on the support column 5 can be adjusted, and after the second mounting part 9 is installed, the positions of the two ends of the sliding rod 7 on the crossbar 6 can be adjusted.

[0069] With the above-mentioned first mounting component 8 and second mounting component 9, this utility model can realize the adjustment of the position of both ends of the crossbar 6 on the support column 5, that is, the adjustment of the height of the crossbar 6, which corresponds to the adjustment of the height of the screen printing light source 3. At the same time, it can realize the adjustment of the position of both ends of the slide bar 7 on the crossbar 6, that is, the adjustment of the longitudinal position of the slide bar 7.

[0070] Furthermore, each fixed rod 2 is provided with a connector 10 at its bottom. The connector 10 contacts the screen printing machine to install the light source fixing bracket 1.

[0071] The height of the connector 10 on the fixed rod 2 is adjustable.

[0072] Please see Figure 1 and Figure 2 ,here Figure 1 This is actually a schematic diagram of the adjustable light source fixing device of this utility model when it is inverted. Figure 2This is a schematic diagram of the structure of the present invention when it is upright. When installed with a screen printing machine, the connector 10 will contact the screen printing machine and be installed on the screen printing machine. At the same time, since the height of the connector 10 can be adjusted on the fixing rod 2, the height of the entire adjustable light source fixing device will also change as the installation position of the connector 10 changes. That is, the present invention can adjust the height of the entire device through the above-mentioned connector 10, further adapting to the curing requirements of the material to be screen printed.

[0073] Furthermore, in this invention, the ink scanning device 4 is disposed in the middle of any crossbar 6, and the scanning port of the ink scanning device 4 is positioned facing the screen printing light source 3.

[0074] This positioning allows the ink scanning device 4 to have a better field of view, enabling it to better scan the screen-printed material and thus providing relevant information for the optimal installation position later.

[0075] Furthermore, the UV LED curing lamp of the screen printing light source 3 in this invention adopts a cold light source device for curing ultraviolet ink.

[0076] This cold light source device for UV ink curing has advantages such as low energy consumption, long lifespan, high efficiency, and less heat generation.

[0077] Furthermore, the wavelength of the screen printing light source 3 in this invention is one of 365nm, 385nm, 395nm, and 405nm.

[0078] Here, the wavelengths mentioned above are all common wavelengths. Different inks have different requirements for specific wavelengths. In this invention, the wavelength is set to one of 365nm, 385nm, 395nm, and 405nm, which can meet the wavelength requirements of different inks as much as possible.

[0079] In summary, the requirements for the light source in this utility model are as follows:

[0080] 1. Selection of light source: The present invention uses a cold light source device for curing ultraviolet (UV) ink, which has the advantages of low energy consumption, long life, high efficiency and less heat generation.

[0081] 2. Wavelength selection: Select a wavelength range suitable for ink curing. Common wavelengths include 365nm, 385nm, 395nm and 405nm. Different inks may have specific requirements for ultraviolet light wavelengths, so the selection needs to be made according to the actual ink curing conditions.

[0082] 3. Light intensity and uniformity: Ensure that the screen printing light source has sufficient light intensity to meet the curing requirements. In addition, uniform light intensity distribution helps to achieve a uniform curing effect and reduce the problem of uneven ink curing.

[0083] 4. Irradiation area and adjustment: Select a suitable irradiation area size according to the screen printing machine used and the curing requirements, and use a screen printing light source with adjustable irradiation width to adapt to printing areas of different sizes.

[0084] 5. Fixing the screen printing light source: The screen printing light source should be firmly fixed on the screen printing machine to ensure that it will not move or loosen during the printing process. At the same time, the position and angle of the screen printing light source should be adjusted according to the printing requirements and ink characteristics to ensure that the ink can be cured evenly.

[0085] This invention plays a crucial role in screen printing systems, ensuring the stability and safety of the screen printing light source, thereby guaranteeing the accuracy and efficiency of the screen printing process. This invention is an indispensable part of screen printing systems, and its design needs to balance stability, safety, and ease of maintenance to ensure the high efficiency and precision of the screen printing process.

[0086] Furthermore, this utility model also proposes a screen printing system, which includes a screen printing machine and the aforementioned adjustable light source fixing device.

[0087] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0088] In this invention, the screen printing light source is mounted on a sliding rod, and both ends of the sliding rod are slidably mounted on a crossbar. This allows the screen printing light source to move laterally along the sliding rod and longitudinally along the crossbar. Simultaneously, the height of the crossbar on the support column is adjustable, enabling the screen printing light source to be adjusted. Based on the above configuration, the screen printing light source is omnidirectionally adjustable. Combined with an ink scanning device to determine the optimal installation position, this ensures product quality under different screen printing light source requirements, improving both the product's aesthetics and functionality.

[0089] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
