[0050] The following exemplary embodiments are described in detail, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numbers in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0051] In existing technology, a single screen printing device can only print a single color on a screen. To perform multi-color overprinting, the screen must be placed on multiple screen printing devices of different colors, and printed separately, to create a multi-color overprint. However, when moving the screen from one screen printing device to another, it is usually necessary to manually detach the screen from the screen printing device, then move the screen from one screen printing device to the next, and then secure the screen to the next screen printing device. This makes it inconvenient to move the screen.

[0052] Based on this, an embodiment of the present application provides a silk screen transmission device, comprising: a conveying mechanism, at least two support frames, at least two positioning mechanisms and at least one mounting tray, the mounting tray being used to mount a silk screen mask, and the mounting tray being located on the conveying mechanism. The support frame is used to be opposite to the silk screen device, and the conveying mechanism is used to transport the mounting tray from one of the support frames to the other support frame, eliminating the need for manual handling of the silk screen mask, thereby making it more convenient to transport the silk screen mask and facilitating overprinting. The positioning mechanism is correspondingly arranged on the support frame, and after the mounting tray is transported to the support frame, the mounting tray on the support frame is positioned by the positioning mechanism to ensure that the mounting tray is positioned accurately, thereby ensuring that the silk screen mask on the mounting tray is positioned accurately, thereby ensuring the accuracy of silk screen printing.

[0053] The embodiments of the present application are described below with reference to the accompanying drawings.

[0054] Reference Figures 1 to 3 The silk screen transmission device provided in the embodiment of the present application includes: a conveying mechanism 100, at least two support frames 200, at least two positioning mechanisms 300, and at least one mounting tray 400. The mounting tray 400 is used to mount the silk screen mask. The mounting tray 400 is located on the conveying mechanism 100. The support frames 200 are used to face the silk screen device, and the conveying mechanism 100 is used to transport the mounting tray 400 from one support frame 200 to the other support frame 200.

[0055] The positioning mechanism 300 is correspondingly provided on the support frame 200 , and the positioning mechanism 300 is used to position the mounting tray 400 on the support frame 200 .

[0056] The support frame 200 is opposite to the screen printing device, which means that the support frame 200 is located directly below the screen printing device. When the mounting tray 400 is located on the support frame 200, the screen printing device is used to screen print the screen mask on the mounting tray 400.

[0057] In some examples, there are multiple support frames 200 , and the support frames 200 are arranged in sequence. Among two adjacent support frames 200 , the rear side of the previous support frame 200 is connected to the front side of the next support frame 200 .

[0058] Specifically, during use, the silk screen mask is mounted on a mounting tray 400, which is then transported by the conveying mechanism 100 to the support frame 200 opposite the silk screen printing device to be used. The positioning mechanism 300 then limits the mounting tray 400 on the support frame 200 to position it. Finally, the silk screen printing device performs silk screen printing on the silk screen mask on the mounting tray 400. After silk screen printing is completed, the mounting tray 400 can be transported by the conveying mechanism 100 to another support frame 200, where a second silk screen printing is performed on the silk screen mask on the mounting tray 400 using the silk screen printing device opposite the support frame 200, thereby completing the overprinting.

[0059] The silk screen transmission device provided in the embodiment of the present application is provided with at least two support frames 200, and the support frames 200 are opposite to the silk screen device. The installation tray 400 is located on the conveying mechanism 100, and the installation tray 400 is sequentially conveyed to each support frame 200 by the conveying mechanism 100. There is no need to manually carry the silk screen mask, and the conveying of the silk screen mask is more convenient, which facilitates overprinting. After the installation tray 400 is conveyed to the support frame 200, the positioning mechanism 300 is used to position the installation tray 400 on the support frame 200 to ensure that the position of the installation tray 400 is accurate, and then the position of the silk screen mask on the installation tray 400 is accurate, thereby ensuring the accuracy of the silk screen printing on the silk screen mask by the silk screen printing device.

[0060] In some embodiments, the conveying mechanism 100 includes a first driving member and a conveying member 110 , the mounting tray 400 is disposed on the conveying member 110 , the conveying member 110 is at least partially located on the support frame 200 , and the first driving member is used to drive the conveying member 110 to move relative to the support frame 200 .

[0061] The conveying member 110 is located between the support frame 200 and the installation tray 400, and the conveying member 110 abuts against the bottom surface of the installation tray 400 to support the installation tray 400 via the conveying member 110. The first driving member drives the conveying member 110 to move relative to the support frame 200, thereby driving the installation tray 400 to move relative to the support frame 200, thereby transporting the installation tray 400.

[0062] Illustratively, the conveying member 110 includes two conveying belts 111 and a connecting member 112 . The connecting member 112 connects the two conveying belts 111 . The two conveying belts 111 are in contact with two sides of the bottom surface of the mounting tray 400 .

[0063] In some embodiments, a closed conveying line body is formed on the conveying member 110, and the mounting tray 400 moves on the conveying line body.

[0064] Reference Figure 3 、 Figure 4 and Figure 5In some embodiments, the positioning mechanism 300 includes at least one second driving member 310 and at least one positioning member 320. The second driving member 310 connects the support frame 200 and the positioning member 320. The second driving member 310 drives the positioning member 320 to move relative to the support frame 200 so that the positioning member 320 abuts against or disengages from the mounting tray 400.

[0065] Specifically, when the installation tray 400 is transported to the support frame 200, the second driving member 310 drives the positioning member 320 to abut against the installation tray 400, so as to accurately position the installation tray 400 through the positioning member 320 to ensure the accuracy of the position of the installation tray 400 on the support frame 200.

[0066] Exemplarily, the second driving member 310 may be a cylinder, a hydraulic cylinder, or a linear motor.

[0067] Reference Figure 3 and Figure 4 In some embodiments, the second driving member 310 includes a first moving member 311 and a second moving member 312, the first moving member 311 connects the second moving member 312 and the support frame 200, and the second moving member 312 is connected to the positioning member 320. The first moving member 311 drives the second moving member 312 and the positioning member 320 to move relative to the support frame 200 along the first direction, and the second moving member 312 drives the positioning member 320 to move relative to the support frame 200 along the second direction.

[0068] The support frame 200 has an opening, and the positioning mechanism 300 is located within the support frame 200 and can extend out of the support frame 200 through the opening. The positioning mechanism 300 is located below the mounting tray 400, and the positioning member 320 abuts against the mounting tray 400 to position the mounting tray 400. It is understood that the positioning member 320 can abut against the bottom surface of the mounting tray 400 or the inner side surface of the mounting tray 400.

[0069] For example, the first moving member 311 and the second moving member 312 may both be cylinders, hydraulic cylinders, or linear motors.

[0070] Specifically, the first direction is Figure 4 The direction indicated by X in the middle, the second direction is Figure 4 When the mounting tray 400 is transported to the support frame 200 , the first moving member 311 and the second moving member 312 respectively drive the positioning member 320 to move relative to the support frame 200 along the first direction and the second direction, so that the positioning member 320 abuts against the mounting tray 400 .

[0071] In some embodiments, the first direction is a vertical direction and the second direction is a horizontal direction.

[0072] In a specific implementation, the positioning member 320 has a first side surface 321 and a second side surface 322 . The first side surface 321 and the second side surface 322 are inclined to each other. The first side surface 321 and the second side surface 322 are in contact with or out of contact with the mounting tray 400 at the same time.

[0073] The first side surface 321 and the second side surface 322 abut against different side surfaces of the mounting tray 400 to simultaneously position the mounting tray 400 in different directions, thereby improving the positioning effect of the positioning member 320 on the mounting tray 400 .

[0074] Exemplarily, the mounting tray 400 is rectangular, and the first side surface 321 and the second side surface 322 are perpendicular to each other, so that the first side surface 321 and the second side surface 322 can abut against the inner corners of the mounting tray 400 at the same time.

[0075] Reference Figure 3 and Figure 5 In some embodiments, the positioning mechanism 300 further includes a first fixed frame 330, a second fixed frame 340 and at least one movable member 350, wherein the movable member 350 movably connects the first fixed frame 330 and the second fixed frame 340, the first fixed frame 330 is connected to the second driving member 310, and the second fixed frame 340 is connected to the positioning member 320.

[0076] The first fixing frame 330 and the second fixing frame 340 are movably connected, allowing the second fixing frame 340 to move a certain amount between the first fixing frame 330. When the positioning member 320 abuts the mounting tray 400, the positioning member 320 can swing slightly relative to the mounting tray 400, thereby preventing the positioning member 320 from being tightly abutted against the mounting tray 400 and causing damage to the mounting tray 400.

[0077] In some embodiments, the positioning mechanism 300 further includes a first mounting frame 360, the first mounting frame 360 being connected to the support frame 200, the second driving member 310 being connected to the first mounting frame 360, the first fixing frame 330 being located on the first mounting frame 360, and the second driving member 310 driving the first fixing frame 330 to move relative to the first mounting frame 360. The provision of the first mounting frame 360 facilitates the connection of the second driving member 310 to the support frame 200, while the first mounting frame 360 can support the second driving member 310 and the first fixing frame 330.

[0078] Furthermore, the positioning mechanism 300 also includes at least one first linear bearing 370, both ends of which are connected to the first mounting frame 360, and the first fixed frame 330 is mounted on the first linear bearing 370. The second driving member 310 drives the first fixed frame 330 to move relative to the first mounting frame, thereby driving the first linear bearing 370 to perform linear motion. By providing the first linear bearing 370, the first fixed frame 330 has better stability when moving relative to the first mounting frame 360. Exemplarily, there are two first linear bearings 370, and the second driving member 310 is located between the two first linear bearings 370.

[0079] In a specific implementation, the movable member 350 includes at least one of a hinge member 351 and an elastic member 352 .

[0080] The hinge member 351 connects the first fixing frame 330 and the second fixing frame 340, allowing the second fixing frame 340 to rotate relative to the first fixing frame 330. The elastic member 352 connects the first fixing frame 330 and the second fixing frame 340 to move relative to the first fixing frame 330. The elasticity of the elastic member 352 limits the movement of the second fixing frame 340 relative to the first fixing frame 330. For example, the elastic member 352 is a spring.

[0081] Exemplarily, the movable member 350 includes a hinge member 351 and two elastic members 352. The hinge member 351 is located between the two elastic members 352 on opposite sides of the hinge member 351. The two elastic members 352 limit the rotation angle of the second fixing frame 340 relative to the first fixing frame 330 and simultaneously act as a buffer between the first fixing frame 330 and the second fixing frame 340.

[0082] In a specific implementation, the number of the positioning members 320 is at least two, and each second positioning member 320 abuts against a different side surface of the mounting tray 400 .

[0083] The at least two positioning members 320 abut against different side surfaces of the mounting tray 400 to position the mounting tray 400 in different directions, thereby improving the positioning effect of the positioning members 320 on the mounting tray 400 .

[0084] For example, the positioning member 320 is a roller. The roller is rotatably mounted on the second fixing frame 340 and abuts against the mounting tray 400. By configuring the positioning member 320 as a roller, the positioning member 320 can move relative to the mounting tray 400 to prevent the positioning member 320 from being tightly abutted against the mounting tray 400 and causing damage to the mounting tray 400.

[0085] In some embodiments, the mounting tray 400 is rectangular, and the positioning mechanism 300 is opposite to the top corners of the mounting tray 400. There are two positioning members 320, which are respectively in contact with two side edges of the mounting tray 400.

[0086] In a specific implementation, the mounting tray 400 includes at least two first connecting rods 410 and at least two second connecting rods 420, the first connecting rods 410 and the second connecting rods 420 are inclined to each other, the first connecting rod 410 connects at least two second connecting rods 420, and the second connecting rod 420 connects at least two first connecting rods 410 to form a mounting frame, which is used to install the silk screen mask.

[0087] The first connecting rod 410 and the second connecting rod 420 are provided to form a mounting frame, and the mounting frame can match the silk screen mask to facilitate the installation of the silk screen mask.

[0088] Exemplarily, the first connecting rod 410 and the second connecting rod 420 are perpendicular to each other, and the mounting frame may be rectangular.

[0089] In some examples, at least one of the first connecting rod 410 and the second connecting rod 420 is provided in plural numbers to form at least two mounting frames.

[0090] By forming multiple mounting frames, each with different sizes, it is possible to mount silk screen masks of different sizes. This makes the mounting tray 400 more versatile. Furthermore, by increasing the number of first connecting rods 410 and second connecting rods 420, the structural strength of the mounting tray 400 can be increased.

[0091] Specifically, the first connecting rod 410 and the second connecting rod 420 are perpendicular to each other, and the first connecting rod 410 and the second connecting rod 420 are connected in a crisscross manner to form at least two rectangular installation frames.

[0092] Illustratively, a mounting portion is provided at the connection between the first connecting rod 410 and the second connecting rod 420 . The mounting portion is used to mount a silk screen mask. The mounting portion is provided to increase the connection strength between the first connecting rod 410 and the second connecting rod 420 .

[0093] In some examples, the positioning mechanism 300 is located below the mounting tray 400 . There are at least two positioning mechanisms 300 , and each positioning mechanism 300 can correspond to a different mounting frame to ensure positioning accuracy for mounting frames of different sizes.

[0094] It is understandable that in the embodiment of the present application, a larger-sized mounting frame can be provided to mount a larger-sized silk-screen mask.

[0095] Reference Figure 2 and Figure 6 In some embodiments, the screen printing transmission device provided by the embodiments of the present application further includes at least one lifting mechanism 500. The lifting mechanism 500 is disposed within the support frame 200 and is located below the installation tray 400. The lifting mechanism 500 drives the installation tray 400 to rise or fall, so that the installation tray 400 is separated from the conveying mechanism 100 or contacts the conveying mechanism 100. When the installation tray 400 is separated from the conveying mechanism 100, the positioning mechanism 300 positions the installation tray 400.

[0096] Specifically, when the installation tray 400 is transported to the support frame 200, the lifting mechanism 500 drives the installation tray 400 upward, allowing the installation tray 400 to detach from the conveying mechanism 100. At this point, the positioning mechanism 300 can be used to position the installation tray 400, and after positioning, the silk screen printing mask on the installation tray 400 can be performed. After the silk screen printing is completed, the lifting mechanism 500 drives the installation tray 400 downward, allowing the installation tray 400 to abut against the conveying mechanism 100. At this point, the installation tray 400 can be transported by the conveying mechanism 100.

[0097] Exemplarily, the lifting mechanism 500 is located in the support frame 200 . When the lifting mechanism 500 drives the installation tray 400 to rise, the lifting mechanism 500 extends out of the support frame 200 through the opening portion of the support frame 200 .

[0098] In this way, by setting up the lifting mechanism 500, when positioning the installation tray 400 and silk-screening the silk-screen mask on the installation tray 400, the installation tray 400 can be detached from the conveying mechanism 100, thereby preventing the conveying mechanism 100 from driving the installation tray 400 to move and affecting the accuracy of positioning and silk-screening.

[0099] Continue to refer to Figure 2 and Figure 6 In some embodiments, the lifting mechanism 500 includes at least one support member 510 and at least one third driving member 520. The third driving member 520 connects the support frame 200 and the support member 510. The support member 510 is located below the installation tray 400 and abuts against the installation tray 400. The third driving member 520 drives the support member 510 to rise or fall, thereby driving the installation tray 400 to rise or fall.

[0100] Exemplarily, the third driving member 520 may be a cylinder, a hydraulic cylinder, or a linear motor.

[0101] Specifically, the third driving member 520 drives the support member 510 upward relative to the support frame 200, thereby driving the installation tray 400 upward relative to the support frame 200, thereby separating the installation tray 400 from the conveying mechanism 100. The third driving member 520 drives the support member 510 downward relative to the support frame 200, thereby driving the installation tray 400 downward relative to the support frame 200, thereby causing the installation tray 400 to abut against the conveying mechanism 100.

[0102] In a specific implementation, the support member 510 has at least one rotating member 513 , and the rotating member 513 abuts against the mounting tray 400 .

[0103] After the lifting mechanism 500 drives the installation tray 400 upward, when the positioning mechanism 300 positions the installation tray 400, the positioning mechanism 300 may push the installation tray 400 to move relative to the lifting mechanism 500. By providing the rotating member 513 on the support member 510, the friction between the rotating member 513 and the installation tray 400 is reduced. This prevents damage to the installation tray 400 due to the high friction between the installation tray 400 and the support member 510 when the installation tray 400 moves relative to the lifting mechanism 500.

[0104] For example, the rotating member 513 is a ball bearing. There are multiple rotating members 513 , and each rotating member 513 is arranged on the supporting member 510 at intervals.

[0105] Continue to refer to Figure 2 and Figure 6 In a specific implementation, the support member 510 includes a support rod 511 and at least one support plate 512 , the support rod 511 connects the support plates 512 , and the rotating member 513 is disposed on the support plate 512 .

[0106] The support plate 512 abuts against the bottom surface of the mounting tray 400 , and the support rod 511 provides support for the support plate 512 .

[0107] Exemplarily, the lifting mechanism 500 further includes a second mounting frame 530 and at least one second linear bearing 540, which is connected to the second mounting frame 530 and the support member 510. The second mounting frame 530 is located within and connected to the support frame 200, and the third driving member 520 is connected to the second mounting frame 530. The third driving member 520 drives the support member 510 to rise and fall, thereby driving the second linear bearing 540 to perform linear motion. The provision of the second linear bearing 540 provides greater stability for the support member 510 during raising and lowering.

[0108] Furthermore, there are two support plates 512 and four second linear bearings 540. Each second linear bearing 540 is located on opposite sides of the third driving member 520, and the two second linear bearings 540 on the same side are connected to the same support plate 512. The support rod 511 is located above and connected to the third driving member 520. The support rod 511 is connected to the lower surface of the support plate 512 and is located between the two second linear bearings 540 on the same side.

[0109] Reference Figure 1 and Figure 7 In some embodiments, the silk screen transmission device provided in the embodiment of the present application also includes a limiting mechanism 600, which is arranged on the support frame 200. When the installation tray 400 is transported to the support frame 200, the limiting mechanism 600 is located on the rear side of the transport direction of the installation tray 400.

[0110] The conveying direction of the installation tray 400 is Figure 1 Direction indicated by the arrow.

[0111] Specifically, after conveying the installation tray 400 onto the support frame 200 along the conveying direction, the conveying mechanism 100 stops. At this point, due to the inertia of the installation tray 400, the installation tray 400 will move in the direction opposite to the conveying direction. The limiting mechanism 600 is positioned behind the installation tray 400 in the conveying direction to limit the distance the installation tray 400 can move in the direction opposite to the conveying direction, thereby preventing the installation tray 400 from significantly deviating from its position on the support frame 200.

[0112] Illustratively, the mounting tray 400 has an escape opening, which is used to avoid the limiting mechanism 600 .

[0113] Continue to refer to Figure 1 and Figure 7 In a specific implementation, the limiting mechanism 600 includes a mounting seat 610 and a limiting member 620 provided on the mounting seat 610 . The limiting member 620 is elastically rotatably connected to the mounting seat 610 , and the mounting seat 610 is connected to the support frame 200 .

[0114] When the mounting tray 400 moves from one support frame 200 to another support frame 200, the limiting mechanism 600 is located below the mounting tray 400, the limiting member 620 abuts against the mounting tray 400, and the limiting member 620, driven by the mounting tray 400, rotates relative to the mounting seat 610 toward the conveying direction of the mounting tray 400.

[0115] The mounting seat 610 is provided to support the limiting member 620 , and the height of the limiting member 620 relative to the support frame 200 can be increased, so that the movement of the mounting tray 400 can be restricted by the limiting member 620 .

[0116] Specifically, the stopper 620 is tilted toward the conveying direction. When the mounting tray 400 abuts against the stopper 620 and moves in the conveying direction, the mounting tray 400 and the conveying mechanism 100 exert pressure on the stopper 620, causing the stopper 620 to rotate relative to the mounting base 610 in the conveying direction. Thus, the mounting tray 400 can be conveyed on the stopper mechanism 600.

[0117] When the installation tray 400 stops being transported, the installation tray 400 is located on the support frame 200 and does not abut against the stopper 620. Due to inertia, the installation tray 400 moves in a direction opposite to the transport direction, moving toward the stopper 620. At this time, the elasticity between the stopper 620 and the mounting base 610 can limit the movement of the installation tray 400.

[0118] Exemplarily, the limiting member 620 has at least one rolling wheel 621 , which is used to abut against the bottom surface of the mounting tray 400 . The friction between the rolling wheel 621 and the mounting tray 400 is small, so that the mounting tray 400 can move on the rolling wheel 621 .

[0119] It is understandable that the limiting member 620 may be elastically rotatably connected to the mounting base 610 via an elastic member, or may be elastically connected to the mounting base 610 via other connection structures.

[0120] Based on the above embodiments, an embodiment of the present application further provides a screen printing device, comprising at least two screen printing devices and any screen printing transmission device in the above embodiments, wherein the screen printing device is correspondingly located above the support frame 200 of the screen printing transmission device.

[0121] The specific structure of the silk screen transmission device is described in detail in the above embodiment and will not be repeated here.

[0122] The silk screen printing device provided in the embodiment of the present application has a silk screen transmission device which is provided with at least two support frames 200, and the support frames 200 are opposite to the silk screen device. The installation tray 400 is located on the conveying mechanism 100, and the installation tray 400 is sequentially conveyed to each support frame 200 by the conveying mechanism 100, eliminating the need for manual handling of the silk screen mask, making it more convenient to convey the silk screen mask, and thus facilitating overprinting. After the installation tray 400 is conveyed to the support frame 200, the positioning mechanism 300 is used to position the installation tray 400 on the support frame 200 to ensure that the installation tray 400 is positioned accurately, thereby ensuring that the silk screen mask on the installation tray 400 is positioned accurately, thereby ensuring that the silk screen device accurately prints on the silk screen mask.
