Utility Model Content

[0003] Therefore, it is necessary to provide a plate feeding mechanism, printing device, and solar cell production system to address the problem of printing presses requiring manual screen replacement, which is time-consuming and labor-intensive.

[0004] Firstly, this application proposes a submission organization, including:

[0005] frame;

[0006] A slide table, disposed on the frame, includes a slot for inserting a screen printing plate, one end of the slot in a first direction being a feeding end, the feeding end being open; a screen printing plate driving assembly, disposed on the slide table, is used to control the screen printing plate located in the slot to exit the slot along the first direction via the feeding end.

[0007] In some embodiments, the slide table is provided with multiple layers of slots, and each layer of slots is arranged sequentially along the second direction, with the feeding end of each slot located on the same side;

[0008] The slide is movably mounted on the frame along a second direction that intersects with the first direction.

[0009] In some embodiments, the slot is disposed through the first direction, and one end of the slot in the first direction serves as the feeding end.

[0010] In some embodiments, the plate feeding mechanism further includes a limiting member arranged on the moving path of the slide table.

[0011] In some embodiments, the plate feeding drive assembly includes a first motor, a first lead screw, a first lead screw pair, and a push rod. The first motor is connected to the lead screw, the first lead screw pair is connected to the push rod and the first lead screw, and the first motor drives the push rod to move along the first direction through the first lead screw and the first lead screw pair.

[0012] The slide also includes a mounting hole and a connecting hole that extend longitudinally along the first direction. The connecting hole connects the mounting hole and the slot. The first lead screw and the first lead screw pair are located in the mounting hole. The push rod passes through the connecting hole and extends into the slot to push the screen out of the slot.

[0013] In some embodiments, the slide table includes two platforms that move synchronously along the second direction, and the two platforms are spaced apart on the frame along a third direction;

[0014] Both of the two platforms are recessed on opposite sides along the third direction, and the two grooves on opposite sides of the two platforms together form a slot.

[0015] The second direction, the first direction, and the third direction intersect each other but are not coplanar.

[0016] In some embodiments, the frame includes two support columns and two mounting brackets that are spaced apart along the third direction, the two mounting brackets are mounted on the two support columns in a one-to-one correspondence, and the two platform bodies are respectively mounted on different mounting brackets;

[0017] The plate feeding mechanism includes a motion drive component, which is disposed on the mounting frame and is used to drive the two platforms to move synchronously along the second direction.

[0018] In some embodiments, the moving drive assembly includes two sets of lead screw assemblies, which are respectively disposed on two mounting brackets and connected to two platform bodies.

[0019] Each of the lead screw assemblies includes a second motor and a second lead screw, the second motor being connected to the second lead screw, and the second lead screw being connected to the platform via a second lead screw pair.

[0020] Secondly, this application proposes a printing apparatus, comprising:

[0026] In the aforementioned plate feeding mechanism, printing apparatus, and solar cell production system, when the printing apparatus needs to replace the screen, once the screen mounting component is in the replacement position, the lifting slide aligns the slot with the screen mounting component. Then, the plate feeding drive assembly pushes / pulls the screen out of the slot. During this process, the screen is gradually transferred to the screen mounting component, completing the installation of the new screen. This eliminates the need for manual installation of new screens, speeding up screen replacement, saving time and labor, and increasing the production efficiency of the printing apparatus.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0036] Furthermore, where applicable, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] To address the time-consuming and labor-intensive problem of screen printing plate replacement, this application first proposes a plate feeding mechanism and a printing apparatus. This printing apparatus can be used in the production of solar cells and can also be applied in other fields.

[0041] It is worth noting in advance that the "first direction," "second direction," and "third direction" mentioned in the embodiments of this application refer to three directions that intersect each other and are not coplanar; specifically, they are roughly perpendicular to each other. In one application, the first direction and the third direction are perpendicular horizontal directions, and the second direction is a vertical direction.

[0042] For ease of explanation, the printing apparatus proposed in this application will be introduced first.

[0043] like Figure 1As shown, the printing apparatus 1000 proposed in this embodiment includes a plate feeding mechanism 100 and a printing press 200. The printing press 200 includes a screen mounting member 210 for mounting a screen printing plate W, and the plate feeding mechanism 100 is used to feed the screen printing plate W to the screen mounting member 210.

[0044] In practical applications, when it is necessary to replace the screen printing plate W on the screen mounting component 210, the screen printing plate W on the receiving part is removed manually or by a robotic arm, and then the plate feeding mechanism 100 delivers a new screen printing plate W to the screen mounting component 210. In this way, during the screen printing plate W replacement process, there is no need for manual installation of the new screen printing plate W, which not only saves manpower but also speeds up production efficiency, saving time and effort.

[0045] In some embodiments, refer to Figure 2 The screen mounting component 210 includes a receiving groove 211 for inserting the screen print W, which extends through the screen print W in a first direction X. In practical applications, the screen feeding mechanism 100 feeds the screen print W into the receiving groove 211 along the first direction X and inserts the screen print W into the receiving groove 211 to define the position of the screen print W.

[0046] Understandably, refer to Figure 2 The screen mounting component 210 also includes a printing window 212, which extends through the screen along the second direction Z. A receiving groove 211 communicates with the printing window 212. The screen surface of the screen W, inserted into the receiving groove 211, is exposed by the printing window 212. In one example, the screen mounting component 210 is provided with a locking member, and the screen W is provided with a locking hole. When the screen W is re-inserted into the receiving groove 211, the locking member engages with the locking hole to fix the screen W on the screen mounting component 210, thereby improving the screen printing effect.

[0047] Understandably, the printing press 200 includes a print head 230. In practical applications, the screen W on the screen mount 210 is first positioned above the workpiece, ensuring the screen surface adheres to the workpiece. Then, the print head 230, located above the screen mount 210, prints ink onto the screen surface of the screen W through the printing window 212, thereby printing the target pattern onto the workpiece. The specific structure of the print head 230 is not limited here.

[0048] In some embodiments, continue to refer to Figure 1 and Figure 2 The printing press 200 also includes a machine base 220, a printing head 230 movably disposed on the machine base 220, and a screen mounting component 210 movably disposed on the machine base 220 along the second direction Z and arranged below the printing head 230.

[0049] The printing head 230 is movably mounted on the machine base 220 in either a third direction Y or a first direction X. Understandably, a movement drive assembly is provided on the machine base 220, connected to the printing head 230, for driving the printing head 230 to move. Optionally, the movement drive assembly includes a third lead screw 222, a third motor (not shown), and a third lead screw pair 223. The third motor is connected to the third lead screw 222 and drives the third lead screw 222 to rotate. The third lead screw pair 223 cooperates with the third lead screw 222 and is driven by the third lead screw 222 to move. The printing head 230 is connected to the third lead screw pair 223 and is driven by the third lead screw pair 223 to move. Optionally, as... Figure 2 As shown, the machine base 220 is provided with a clearance hole 221 that runs through the second direction Z. The third lead screw 222 is installed in the clearance hole 221. The third lead screw pair 223 passes through the clearance hole 221 and is connected to the printing head 230 below the machine base 220.

[0050] The screen mounting component 210 is vertically movable along the second direction Z on the machine base 220. Optionally, the screen mounting component 210 is raised and lowered in cooperation with a lead screw, lead screw pair, and motor. In practical applications, when the screen W needs to be replaced, the screen mounting component 210 descends along the second direction Z to the screen changing position, away from the printing head 230, to facilitate the removal of the screen W. Then, the plate feeding mechanism 100 conveys a new screen W to the screen mounting component 210 at the screen changing position. Once the new screen W is in place, the screen mounting component 210 rises along the second direction Z to the printing position, ready for the printing head 230 to perform the printing operation.

[0051] At this point, the screen mounting component 210 is set to be height adjustable to facilitate the replacement of the screen W.

[0052] In other embodiments, the print head 230 may be configured to be height-adjustable to avoid the screen mounting component 210 from replacing the screen W, while the screen mounting component 210 is designed to be in a fixed position.

[0053] The following describes in detail the submission organization 100 proposed in the embodiments of this application.

[0054] Please refer to Figure 3 The plate feeding mechanism 100 proposed in this application embodiment includes a frame 10, a slide table 20, and a plate feeding drive assembly 30. The slide table 20 includes a slot 21 for inserting the screen printing plate W. One end of the slot 21 in the first direction X is a feeding end D, which is open. The slide table 20 is movably disposed on the frame 10 along a second direction Z intersecting the first direction X. The plate feeding drive assembly 30 is disposed on the slide table 20 and is used to control the screen printing plate W located in the slot 21 to exit the slot 21 along the first direction X via the feeding end D.

[0055] Slot 21 is used to store the screen printing plate W. Specifically, slot 21 is horizontally opened along the first direction X, and the screen printing plate W is inserted into slot 21 along the first direction X. Alternatively, one end of slot 21 in the first direction X can be open as a feeding end D, and the other end can be closed. In this case, the feeding end D of slot 21 can serve as the inlet end, that is, the screen printing plate W is inserted into slot 21 through the feeding end D. Alternatively, both ends of slot 21 in the first direction X can be open, with one end serving as the feeding end D and the other end serving as the inlet end.

[0056] The screen printing drive assembly 30 is mounted on the slide table 20 and is used to push the screen printing plate W in the slot 21 out of the slot 21 via the feed end D and into the receiving groove 211. As an example, the screen printing drive assembly 30 includes a cylinder and a push plate. The cylinder is connected to the push plate, mounted on the frame 10, and connected to the push plate, for driving the push plate to move along a first direction X. The push plate is arranged on the side of the slot 21 opposite to the feed end D, and during movement, it can be inserted into the slot 21 to push the screen printing plate W out of the slot 21 via the feed end D.

[0057] The slide 20 is movable in the second direction Z. In practical applications, by moving the slide 20 up and down, the slot 21 on the slide 20 is aligned with the receiving groove 211 on the screen mount 210, so that the screen W in the slot 21 can be smoothly inserted into the receiving groove 211. In this way, the plate feeding mechanism 100 can be matched with various printing presses 200 with different plate changing positions of the screen mount 210, and its application range is wide.

[0058] In practical applications, when the printing apparatus 1000 needs to replace the screen printing plate W, once the screen mounting component 210 is in the replacement position, the lifting slide 20 aligns the slot 21 with the receiving groove 211 of the screen mounting component 210. Then, the plate feeding drive assembly 30 pushes / pulls out the screen printing plate W from the slot 21. As the screen printing plate W is pushed out of the slot 21, it is gradually inserted into the receiving groove 211 until it is fully inserted, completing the installation of the new screen printing plate W. In this way, no manual installation of the new screen printing plate W is required, which speeds up the replacement of the screen printing plate W, saves time and labor, and increases the production efficiency of the printing apparatus 1000.

[0059] In some embodiments, refer to Figure 3 The slide table 20 is provided with multiple layers of slots 21, and each layer of slots 21 is arranged sequentially along the second direction Z. The feeding end D of each slot 21 is located on the same side.

[0060] In practical applications, each slot houses 21 memory modules (W). Combined with... Figure 1 and Figure 2Understanding the process: each time the screen printing plate W needs to be replaced, the plate feeding mechanism 100 controls the slide 20 to rise and fall, aligning one of the slots 21 with the receiving groove 211 of the screen printing plate mounting component 210. Then, the plate feeding drive assembly 30 pushes / pulls out the screen printing plate W from the slot 21, allowing it to be inserted into the receiving groove 211. When all the screen printing plates W stored in the plate feeding mechanism 100 are used up, a new screen printing plate W is mechanically or manually replaced in preparation for the next screen printing plate replacement.

[0061] At this time, the number of screen printing plates W stored in the plate feeding mechanism 100 increases. After each loading, the number of times a new screen printing plate W is provided to the printing press 200 increases, which can reduce the number of times the plate feeding mechanism 100 is loaded manually or mechanically, and speed up the plate change efficiency.

[0062] In some embodiments, refer to Figure 3 The slot 21 is provided through the first direction X, and one end of the slot 21 in the first direction X serves as the feeding end D.

[0063] That is, both ends of the slot 21 are open, which makes it easy to process. On the other hand, the other open end of the slot 21 opposite to the feeding end D can be used to feed the screen printing plate W into the slot 21, so that the feeding and feeding of the screen printing plate W will not interfere with each other, and there is no need to change the direction of the feeding mechanism 100. The feeding mechanism 100 is more convenient to use and helps to improve production efficiency.

[0064] In some embodiments, refer to Figure 3 The plate feeding mechanism 100 also includes a limiting member 50, which is arranged on the moving path of the slide table 20. Optionally, the limiting member 50 includes a limiting post disposed below the slide table 20 to prevent the slide table 20 from falling to the ground and damaging the screen printing plate W. Alternatively, the limiting member 50 includes a limiting block (not shown) disposed above the slide table 20 to prevent the slide table 20 from rising too quickly and derailing, thus preventing damage to the screen printing plate W.

[0065] At this time, the setting of the limit component 50 helps to improve the stroke safety of the slide table 20, improve the operational reliability of the plate feeding mechanism 100, and reduce the risk of damage to the screen W.

[0066] In some embodiments, refer to Figure 4 The screen printing drive assembly 30 includes a first motor 31, a first lead screw 32, a first lead screw pair 33, and a push rod 34. The first motor 31 is connected to the first lead screw 32, and the first lead screw pair 33 is connected to the push rod 34 and the first lead screw 32. The first motor 31 drives the push rod 34 to move along the first direction X through the first lead screw 32 and the first lead screw pair 33. The slide table 20 also includes a mounting hole 22 and a connecting hole 23 extending longitudinally along the first direction X. The connecting hole 23 connects the mounting hole 22 and the slot 21. The first lead screw 32 and the first lead screw pair 33 are located in the mounting hole 22. The push rod 34 passes through the connecting hole 23 and extends into the slot 21 to push the screen printing plate W out of the slot 21.

[0067] Understandably, the first lead screw 32 extends along the first direction X. Optionally, in order to make the force on both ends of the screen W even, a first motor 31, a first lead screw 32 and a first lead screw pair 33 are provided on both sides of the slot 21 in the third direction Y. Correspondingly, the slide table 20 is provided with a connecting hole 23 and a mounting hole 22 on both sides of the slot 21.

[0068] In practical applications, the first motor 31 drives the first lead screw 32 to rotate. The first lead screw pair 33 cooperates with the first lead screw 32 and moves along the first direction X under the action of the first lead screw 32. The first lead screw pair 33 drives the push rod 34 to move along the first direction X. The push rod 34 abuts against the end of the screen W away from the feeding end D. When the push rod 34 moves, it pushes the screen W out of the slot 21. At this time, the screen W can be smoothly withdrawn from the slot 21, and the structure is simple and easy to implement.

[0069] In some embodiments, refer to Figure 3 The slide table 20 includes two platforms 24 that move synchronously along the second direction Z. The two platforms 24 are spaced apart on the frame 10 along the third direction Y. Each of the two platforms 24 has a groove 21a recessed on its opposite sides along the third direction Y. The two grooves 21a of the two platforms 24 that are directly opposite each other along the third direction Y together form a slot 21.

[0070] Understandably, the two slots 21a constituting the slot 21 are arranged at the same height in the second direction Z, and at least one end of the two slots 21a in the first direction X is open to form the feeding end D of the slot 21. In practical applications, the edge of the screen W is inserted into the two side slots 21a of the slot 21, and the middle area of ​​the screen W is suspended between the two platforms 24.

[0071] Thus, the overall size and weight of the slide table 20 are relatively small, which helps to reduce costs.

[0072] In some embodiments, refer to Figure 3 The frame 10 includes two support columns 11 and two mounting brackets 12, each spaced apart along the third direction Y. The two mounting brackets 12 are mounted one-to-one on the two support columns 11, and the two platforms 24 are respectively mounted on different mounting brackets 12. The plate feeding mechanism 100 includes a slide drive assembly 40, which is located on the mounting bracket 12 and is used to drive the two platforms 24 to move synchronously along the second direction Z.

[0073] Understandably, two platforms 24 are positioned between two mounting brackets 12. In this configuration, a support column 11 and a mounting bracket 12 form a support structure for supporting one platform 24. In practical applications, the distance between the two platforms 24 can be altered by changing the spacing between the two support structures in the third direction Y, thus adapting to different screen sizes W. This allows the plate feeding mechanism 100 to be compatible with printing presses 200 of varying screen sizes at low cost, resulting in a wide range of applications.

[0074] Preferably, the mounting frame 12, support column 11, and platform 24 are arranged symmetrically relative to the plane perpendicular to the third direction Y. In this way, by independently mass-producing the mounting frame 12, support column 11, and platform 24, and then assembling the three to form the plate feeding mechanism 100, the production and preparation of the plate feeding mechanism can be simplified and the cost reduced.

[0075] Optionally, part of the mounting bracket 12 is supported on the support column 11, and the other part is supported on the machine base 220 of the printing press 200, so that the mounting bracket 12 provides more stable support.

[0076] In some embodiments, refer to Figure 3 Each mounting bracket 12 is provided with a set of slide drive assemblies 40. Each set of slide drive assemblies 40 includes a second motor (not shown) and a second lead screw 41. The second motor is connected to the second lead screw 41, and the second lead screw 41 is connected to the stage body 24 via a second lead screw pair (not shown).

[0077] When the second motor rotates, it drives the second lead screw 41 to rotate. When the second lead screw 41 rotates, it drives the second lead screw pair to rise and fall along the second direction Z, thereby driving the platform 24 to rise and fall. At this time, not only can the platform 24 be raised and lowered, but the second lead screw 41 can also play a guiding role, making the raising and lowering of the platform 24 more stable.

[0078] Of course, in other embodiments, the slide drive assembly 40 may also adopt a structure such as a cylinder to drive the stage 24 to rise and fall.

[0079] Furthermore, this application also proposes a solar cell production system, including the printing apparatus described in the above embodiments. This solar cell production system incorporates all the beneficial effects of the above embodiments, which will not be elaborated upon here.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
