[0034] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0035] In the present application, the terms “mount”, “set”, “provided with”, “connect”, “connected” should be understood broadly. For example, it can be fixed connection, detachable connection, or integral structure; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] In addition, the terms “first”, “second” and the like are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise stated, the meaning of “multiple” is two or more.

[0037] With the development of economy, the demand for energy is becoming tight, and the energy situation is becoming increasingly urgent, which prompts China to accelerate the use of solar energy, wind energy and other renewable energy to optimize the energy structure, and thus to promote the sustainable development of energy. In this process, solar energy plays an indispensable key role.

[0038] In the screen printing process based on solar cell pieces, the core machine is a printing machine. Only by ensuring that the printing machine runs stably and with high precision can the product quality be guaranteed. The screen printing process mainly relies on the movement of the printing head of the printing machine to print the paste on the cell piece to form the electrode. Therefore, ensuring the printing precision and the stable operation of the equipment is crucial to ensuring the product yield.

[0039] When the screen printing line has printing defects or screen problems, the staff needs to repair, inspect and other operations on the screen. If the screen is disassembled, a lot of production capacity will be wasted. If the screen is not disassembled, due to the position of the screen in the turntable inside the machine shell, the staff must enter the machine shell after stopping the machine to work. Due to the limitation of the space position, the staff can only kneel on the turntable of the printing machine to operate. The current machine is generally designed as a lightweight turntable. Frequent kneeling of personnel will cause the turntable to tilt, thereby affecting the printing quality and causing printing defects.

[0040] In view of this point, some embodiments of the present application provide a printing machine auxiliary operation device, which can prevent the turntable of the printing machine from shaking or tilting when the operator operates the screen on the turntable, and facilitate the operator to perform operations such as inspection, adjustment, cleaning or replacement, thereby improving the convenience and efficiency of operation and providing a safe and stable operation platform for the operator.

[0041] The present application will be described in detail below through specific embodiments:

[0042] The printing machine auxiliary operation device of the embodiments of the present application, as shown in Figures 1-5 A printing machine auxiliary operation device, the printing machine comprising a machine shell and a turntable arranged in the machine shell, the turntable being provided with a plurality of screens distributed circumferentially around the rotation center of the turntable, and the machine shell further comprising an operation port, the printing machine auxiliary operation device comprising:

[0043] A support body 10, the support body 10 having opposite first and second surfaces 11 and 12, the first surface 11 being used to support the human body;

[0044] A first support part 20, the first support part 20 being arranged on the second surface 12, and the first support part 20 being used to lap on the middle part of the turntable;

[0045] A second support part 30, the second support part 30 being arranged on the second surface 12, and the second support part 30 being used to lap on the lower frame of the operation port.

[0046] The printing machine auxiliary operation device provided by the embodiment of the present application comprises a support body 10, a first surface 11 of the support body 10 is used for supporting a human body, a second surface 12 of the support body 10 is used for mounting a first support part 20 and a second support part 30, the first support part 20 is overlapped on a middle part of a rotary table, the second support part 30 is overlapped on a lower edge frame of an operation opening, and a stable support structure is formed. Since the first support part 20 is overlapped on the middle part of the rotary table, the middle part of the rotary table generally has certain structural strength and stability. When an operator kneels on the first surface 11 of the support body 10 to operate, the rotary table of the printing machine will not shake or incline, and the operator is closer to the rotary table and the screen plate and other components in the printing machine, which facilitates the operator to check, adjust, clean or replace the screen plate on the rotary table, reduces the labor intensity of the operator, improves the convenience and efficiency of the operation, provides a safe and stable operation platform for the operator, reduces the risk of operation failure caused by instability of the device, and improves the quality and stability of the printing operation.

[0047] Further, in order to enhance the stability of the entire auxiliary operation device, as shown in Figures 2-3 The printing machine auxiliary operation device further comprises a limiting structure 40, and the limiting structure 40 is used for clamping with the lower edge frame of the operation opening to fix the radial position of the support body 10 along the rotary table.

[0048] The limiting structure 40 clamps with the lower edge frame of the operation opening to accurately position the support body 10 in the radial direction. Since the limiting structure 40 fixes the radial position of the support body 10 along the rotary table, the fixed radial position can prevent the support body 10 from being displaced inadvertently by the operator, avoids the risk of the operator falling due to loss of balance, and enables the operator to more accurately position his / her body position and the position of the operation tool when performing relevant operations above the rotary table, reduces the operation error caused by the change of the position of the support body 10, and thus improves the quality and precision of the printing operation.

[0049] The limiting structure 40 can have various implementation manners, such as a clamping groove or a clamping block matched with the shape of the lower edge frame of the operation opening. In a possible implementation manner, as shown in Figures 2-3 The limiting structure 40 comprises a first limiting part 41 and a second limiting part 42, the first limiting part 41 and the second limiting part 42 are arranged at intervals along the arrangement direction of the first support part 20 and the second support part 30, and the interval between the first limiting part 41 and the second limiting part 42 is matched with the thickness of the lower edge frame of the operation opening.

[0050] The first limiting part 41 and the second limiting part 42 are arranged in the arrangement direction of the first supporting part 20 and the second supporting part 30, and are spaced apart, so that the first limiting part 41 and the second limiting part 42 are similar to the structure of a clamp, and the lower frame of the operation port is clamped in the middle, the lower frame of the operation port can be clamped from two different positions, forming a bidirectional limiting effect, effectively preventing the support body 10 from translating in the radial direction of the turntable, and more effectively resisting the force in the radial direction of the support body 10 from different directions. The spaced limiting structure 40 only needs to align the gap between the first limiting part 41 and the second limiting part 42 when installing, and then the limiting structure 40 can be clamped with the lower frame through simple operation (such as pressing or sliding). When disassembling, the operation is relatively simple. Stable radial limiting can reduce unnecessary shaking and displacement of the support body 10 during operation, thereby reducing the friction and collision between the first supporting part 20, the second supporting part 30, the limiting structure 40 itself and other parts of the printing machine.

[0051] In other possible implementations, the limiting structure 40 can also only include one limiting part for clamping with the inner frame or the outer frame edge of the lower frame of the operation port, or a clamping groove is provided on the lower frame of the operation port, and the limiting part is provided as a clamping protrusion for cooperation.

[0052] In this embodiment, as shown in Figure 2 , the first supporting part 20 and the second supporting part 30 form an accommodating space 50, and the accommodating space 50 is used to accommodate the screen plate of the turntable close to the operation port.

[0053] The accommodating space 50 formed between the first supporting part 20 and the second supporting part 30 is used to accommodate the screen plate of the turntable close to the operation port. The existence of the accommodating space 50 makes the screen plate close to the operation port not collide with the first supporting part 20 and the second supporting part 30 when the device is used and the operator operates. The accommodating space 50 is used to accommodate the screen plate close to the operation port, which can effectively protect the screen plate close to the operation port, reduce the risk of equipment damage, and reduce maintenance cost.

[0054] Specifically, as shown in Figure 4 , the support body 10 includes a first plate body 13, a second plate body 14 and a third plate body 15 arranged in sequence along the length direction of the support body 10. The first plate body 13 is a rectangular plate body, and the first plate body 13 is located above the middle part of the turntable. The second plate body 14 is a trapezoidal plate body, and the short side of the trapezoidal plate body is connected with the first plate body 13. The third plate body 15 is a rectangular plate body, and the long side of the trapezoidal plate body is connected with the third plate body 15. The first supporting part 20 is arranged on the first plate body 13, and the second supporting part 30 is arranged on the third plate body 15.

[0055] The first plate body 13, the second plate body 14 and the third plate body 15 are sequentially connected to form a whole support structure, and a trapezoidal plate body is used for transition. The short side of the trapezoidal plate body is connected with the first plate body 13. Since the space in the middle of the rotary table is limited, the size of the first plate body 13 is relatively narrow. In order to provide more space for the operator to operate, the long side of the trapezoidal plate body is connected with the third plate body 15. The trapezoidal structure plays a role in transition connection, so that the size of the third plate body 15 is relatively wide, thereby providing a more stable support effect. The support body 10 structure composed of plate bodies with different shapes can well adapt to the layout of the rotary table and the operation opening of the printing machine, improve the carrying capacity and stability of the whole support body 10, and ensure that the support body 10 will not be deformed or damaged due to uneven stress during operation, so that the support body 10 can realize efficient support function in a limited space, and improve the adaptability of the whole auxiliary operation device to the printing machine.

[0056] In other embodiments, the support body 10 can also be a whole rectangular support plate which extends from above the middle of the rotary table to above the lower edge frame of the operation opening.

[0057] Further, in some embodiments, as shown in Figure 2 The first support part 20 includes a first sub-support part 21, a second sub-support part 22 and a third sub-support part 23. The first sub-support part 21 is arranged on the first edge of the first plate body 13 away from the second plate body 14. The second sub-support part 22 is arranged on the second edge adjacent to the first edge. The third sub-support part 23 is arranged on the third edge adjacent to the first edge.

[0058] The first sub-support part 21 is located on the first edge of the first plate body 13 away from the second plate body 14. The second sub-support part 22 and the third sub-support part 23 are arranged on the second edge and the third edge adjacent to the first edge, respectively, to form a surrounding support structure which surrounds the peripheral part of the first plate body 13 in the plane. The first plate body 13 can be supported from multiple directions above the middle of the rotary table, and the contact with the middle of the rotary table forms a multi-point support mode. Since the first sub-support part 21, the second sub-support part 22 and the third sub-support part 23 support the middle of the rotary table from different directions, the external force from multiple directions can be effectively resisted. During the operation of the operator, vibration or other unstable factors may occur. The layout of the three sub-support parts can better adapt to these situations, flexibly adjust the distribution of the support force, and thus reduce the shaking of the support body 10.

[0059] In other embodiments, only the first sub-support part 21 can be provided, and the size of the first sub-support part 21 is designed to be relatively wide to provide good support. Alternatively, the first support part 20 includes two sub-support parts arranged opposite to each other.

[0060] In the embodiment, as shown inFigure 2 As shown, the second support part 30 is arranged on the fourth edge of the third plate body 15 away from the second plate body 14.

[0061] The second support part 30 is arranged on the fourth edge of the third plate body 15 away from the second plate body 14, and is opposite to the first support part 20 in space. The second support part 30 is arranged along the edge of the third plate body 15 and overlaps the lower edge frame of the operation port to achieve a large contact area with the lower edge frame of the operation port. The second support part 30 can efficiently transmit the weight of the operator and external force generated during operation to the lower edge frame of the operation port, and cooperates with the first support part 20 to transmit force to the middle part of the turntable, so as to avoid the damage of device components caused by excessive local stress, and also enhances the carrying capacity of the entire device and prolongs the service life of the device.

[0062] As shown in the drawings, Figure 2 The printing machine auxiliary operation device further comprises a reinforcing structure 60 arranged on the second surface 12.

[0063] The reinforcing structure 60 is arranged on the second surface 12 of the support body 10. When the operator stands on the support body 10, the body weight and the force generated during operation will cause the support body 10 to have a deformation trend. The reinforcing structure 60 resists this deformation by its rigidity and strength, so that the support body 10 can maintain a stable shape, thereby ensuring the safety of the operator and the accuracy of the operation. When cooperating with the first support part 20 and the second support part 30, the reinforcing structure 60 plays a role in transmitting and dispersing force. The reinforcing structure 60 can significantly improve the strength and rigidity of the support body 10. The reinforcing structure 60 can disperse the stress concentration points on the support body 10, so that the force is more evenly distributed inside the support body 10. The reinforcing structure 60 makes the entire device more stable in force transmission and support when working with the first support part 20 and the second support part 30.

[0064] The reinforcing structure 60 can have various implementations. For example, it can be a strip-shaped reinforcing rib arranged along the length direction or the width direction of the support body 10 to increase the bending strength of the support body 10. It can also be a block-shaped reinforcing structure 60 used to reinforce the connection points of the first support part 20 and the second support part 30 with the support body 10 to disperse the concentrated stress. In the present embodiment, as shown in the drawings, Figure 5 The reinforcing structure 60 comprises a plurality of rectangular frames 61 connected to each other, and the plurality of rectangular frames 61 are arranged along the length direction of the support body 10. One end of one of the rectangular frames 61 is connected to the second support part 30.

[0065] The plurality of mutually connected rectangular frames 61 are arranged along the length direction of the support body 10, effectively utilizing the space structure of the support body 10, the rectangular frames 61 arranged along the length direction can significantly enhance the bending and shear strength of the support body 10, the rectangular frames 61 are mutually connected, one end of one of the rectangular frames 61 is connected with the second support part 30, forming a continuous whole structure, enhancing the stability of the whole support system, the plurality of mutually connected rectangular frames 61 can effectively disperse the force concentrated in a certain part to the whole support body 10. At the same time, the structure of the rectangular frame 61 is relatively simple, the manufacturing process is relatively mature, and it is also relatively convenient to install.

[0066] Further, as shown in Figure 5 The reinforcing structure 60 further comprises a first reinforcing rib 62, the first reinforcing rib 62 connects the long side of one of the rectangular frames 61 and the end of the second support part 30.

[0067] The first reinforcing rib 62 plays a reinforcing role on the connecting end point of the rectangular frame 61 and the second support part 30, when the force acts on the second support part 30, part of the force is transmitted to the support body 10 through its own structure, and the other part of the force can be transmitted to the rectangular frame 61 connected through the first reinforcing rib 62, in the process of force transmission, the first reinforcing rib 62 can also adjust the stress distribution between the rectangular frame 61 and the second support part 30, the first reinforcing rib 62 as a part of the reinforcing structure 60 indirectly enhances the overall performance of the support body 10, and further improves the stability and anti-deformation ability of the whole printing machine auxiliary operation device.

[0068] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
