These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0042] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0043] The terms “first,” “second,” “third,” and “fourth,” etc. (if present), in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0044] As mentioned in the background section, in a production line, the materials for producing solar cells are transported between various processes via multiple belt conveyors. When a device in one process malfunctions, the entire production line needs to be shut down for maintenance, leading to an accumulation of solar cell production materials and thus affecting production efficiency.
[0045] For example, in the screen printing process, a cassette furnace is used to heat and cure the grid lines of the battery cell production material. During cassette furnace unloading, a robotic arm places a basket containing the battery cell production material into a designated unloading position. Then, a conveyor mechanism sequentially transports each basket to a feeding machine, transition machine, transfer machine, LED furnace, and other machines. When these machines malfunction, the baskets become stuck inside the cassette furnace cavity and cannot be discharged in time, thus affecting the battery cell production efficiency and causing defective cells such as hazy blackening due to continuous heating.
[0046] To address the aforementioned problems in the existing technology, this utility model provides an auxiliary conveying structure and a conveying system. The auxiliary conveying structure includes a frame, at least two first conveying components, at least one second conveying component, and at least two turning mechanisms. The first conveying components are spaced apart on the frame. The second conveying components are mounted on the frame and located between the two first conveying components. The turning mechanisms are mounted on the frame, with each turning mechanism corresponding to a first conveying component. The turning mechanisms are used to receive the conveyed items and can switch between a first state and a second state. In the first state, the turning mechanism transports the item to be conveyed to its corresponding first conveying component; in the second state, the turning mechanism transports the item to be conveyed to the second conveying component, which then transports it to another first conveying component. This allows for switching of the transport track, enabling the item to be conveyed to be transferred to another production line, thus avoiding the accumulation of items and improving production efficiency.
[0047] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0048] Reference Figure 1 As shown, the auxiliary conveying structure provided in this application embodiment includes a frame 100, at least two first conveying components 200, at least one second conveying component 300, and at least two steering mechanisms 400.
[0049] Each first conveying assembly 200 is spaced apart on the frame 100 and is used to transport the parts to be conveyed to the conveying units of the production line. A second conveying assembly 300 is disposed on the frame 100 and located between the two first conveying assemblies 200. A steering mechanism 400 is disposed on the frame 100, and each steering mechanism 400 corresponds to each first conveying assembly 200. The steering mechanism 400 is used to receive the parts to be conveyed and is configured to move relative to the first conveying assembly 200 to switch between a first state and a second state.
[0050] In the first state, the steering mechanism 400 transports the item to be transported to the corresponding first conveying component 200; in the second state, the steering mechanism 400 transports the item to be transported to the second conveying component 300, which then transports it to another first conveying component 200.
[0051] It is understood that the auxiliary conveying structure provided in this application embodiment can be used on a conveying system for transporting parts to be transported. The conveying system may include two production lines, each of which transports parts to be transported through a conveying unit. The auxiliary conveying structure is disposed between the two conveying units, and each of the first conveying components 200 of the auxiliary conveying structure is disposed corresponding to each conveying unit.
[0052] For example, this conveying system can be used in the production of solar cells, and the items to be conveyed can be baskets containing production materials for solar cells. The auxiliary conveying structure provided in this application embodiment will be described below using the screen printing process as an example.
[0053] The steering mechanism 400 can be positioned at the unloading position of the robot arm in the gasket furnace. When both production lines are operating normally, both steering mechanisms 400 are in the first state. At this time, the steering mechanism 400 can receive the parts to be conveyed from the robot arm and transport them to the corresponding first conveying component 200. Then, the first conveying component 200 transports the parts to be conveyed to the conveying unit.
[0054] When one of the production lines needs to be shut down for maintenance, the first conveying component 200 corresponding to the conveying unit of that production line can stop working, and the turning mechanism 400 corresponding to the first conveying component 200 is in a second state. At this time, the turning mechanism 400 can receive the parts to be conveyed from the robotic arm and transport them to the second conveying component 300, which then transports them to another first conveying component 200, thereby switching the transport track and allowing the parts to be conveyed to be transferred to another production line. This avoids the accumulation and blockage of the parts to be conveyed in the gas cylinder, thus improving production efficiency.
[0055] Reference Figure 1 and Figure 2 As shown, in some embodiments, the steering mechanism 400 includes a lifting member 410 and a third conveying assembly 420. The lifting member 410 is disposed on the frame 100, and the third conveying assembly 420 is disposed on the lifting member 410. The third conveying assembly 420 is disposed corresponding to the second conveying assembly 300, and the third conveying assembly 420 is used to receive the conveying component.
[0056] In the first state, the lifting member 410 drives the third conveying component 420 to correspond with the first conveying component 200 so that the part to be conveyed falls onto the first conveying component 200; in the second state, the lifting member 410 drives the third conveying component 420 to correspond with the second conveying component 300, and the third conveying component 420 transports the part to be conveyed onto the second conveying component 300.
[0057] In the above embodiment, the lifting member 410 is used to drive the third conveying component 420 to move vertically relative to the first conveying component 200, so as to receive the component to be conveyed through the third conveying component 420.
[0058] In the first state, the third conveying component 420 stops working, and the lifting member 410 first drives the third conveying component 420 to move upward to receive the item to be conveyed; then, the lifting member 410 drives the third conveying component 420 to move downward until the third conveying component 420 moves to the same height as the first conveying component 200, so that the item to be conveyed falls on the first conveying component 200, thereby enabling the first conveying component 200 to transport the item to be conveyed to the conveying unit.
[0059] Reference Figure 4 As shown, in the second state, the third conveying component 420 first stops working, and the lifting component 410 first drives the third conveying component 420 to move upward to receive the component to be conveyed; then, it drives the third conveying component 420 to move downward until the third conveying component 420 moves to the same height as the second conveying component 300. The third conveying component 420 starts working and transports the component to be conveyed onto the second conveying component 300. The second conveying component 300 then transports the component to be conveyed onto the other first conveying component 200 opposite to it.
[0060] For example, the lifting component 410 can be a telescopic cylinder, a telescopic hydraulic cylinder, etc. The first conveying assembly 200, the second conveying assembly 300, and the third conveying assembly 420 can all be belt conveyors, such as belt conveyors, chain conveyors, etc., and this application embodiment does not impose too many restrictions on this.
[0061] Reference Figure 1 and Figure 2 As shown, in some embodiments, the auxiliary conveying structure provided in this application further includes at least two first mounting bases 120;
[0062] The frame 100 is provided with at least two mounting holes 110, the first mounting base 120 is correspondingly provided on the side wall of the mounting hole 110, and the lifting member 410 is correspondingly provided on the first mounting base 120.
[0063] In the above embodiment, the lifting member 410 is mounted in the mounting hole 110 via the first mounting base 120, so that the lifting member 410 is located below the first conveying assembly 200 and the second conveying assembly 300, thereby making full use of the mounting space on the frame 100 and avoiding mutual interference. The lifting member 410 can drive the third conveying assembly 420 to move relative to the first conveying assembly 200 through the mounting hole 110.
[0064] Reference Figure 1 and Figure 3 As shown, in some embodiments, the first conveying component 200 is disposed above the mounting hole 110. The first conveying component 200 has a clearance through hole 201, which corresponds to the mounting hole 110, so that the third conveying component 420 moves relative to the first conveying component 200 through the clearance through hole 201.
[0065] In the above embodiment, the cross-sectional area of the component to be transported can be larger than the cross-sectional area of the clearance through hole 201 on the first transport assembly 200. Thus, in the first state, the third transport assembly 420, under the action of the lifting member 410, can sequentially pass through the mounting hole 110 and the clearance through hole 201 to receive the component to be transported. Then, the lifting member 410 drives the third transport assembly 420 to move downwards. When the third transport assembly 420 passes through the clearance through hole 201, the component to be transported is intercepted by the first transport assembly 200, so that the component to be transported is conveyed to the transport unit via the first transport assembly 200.
[0066] This structural design allows for a more compact overall structure and ensures the stability of the transported items, preventing them from falling off.
[0067] Reference Figure 1 and Figure 3 As shown, in some embodiments, the first conveying assembly 200 includes a frame 210, a drive unit (not shown), a drive wheel set 220, a first conveyor belt 230, and a second conveyor belt 240.
[0068] The frame 210 is mounted on the frame 100, the drive unit is mounted on the frame 210, the drive wheel set 220 is rotatably mounted on the frame 210, the drive unit is connected to the drive wheel set 220, and the first transmission belt 230 and the second transmission belt 240 are both sleeved on the drive wheel set 220.
[0069] The frame 210 has a clearance through hole 201, and the first conveyor belt 230 and the second conveyor belt 240 are located on opposite sides of the clearance through hole 201.
[0070] In the above embodiment, the clearance through-hole 201 is located on the frame 210, and the first conveyor belt 230 and the second conveyor belt 240 are respectively located on opposite sides of the clearance through-hole 201. Thus, when the third conveying assembly 420 passes through the clearance through-hole 201 under the action of the lifting member 410, the part to be conveyed can be intercepted by the frame 210, causing it to fall onto the first and second conveyor belts. The drive wheel assembly 220, under the action of the driving member, drives the first conveyor belt 230 and the second conveyor belt 240 to rotate, thereby transporting the part to be conveyed to the conveying unit.
[0071] Specifically, refer to Figure 3 As shown, the driving component can be a drive motor. The drive wheel set 220 can include a driving wheel 221 and three driven wheels 222. The driving wheel 221 and one driven wheel 222 are located on the same side of the frame 210. The driving wheel 221 and the driven wheel 222 are connected by a synchronous pulley shaft 223. The other two driven wheels 222 are located on the opposite side of the frame 210. The two driven wheels 222 are also connected by a synchronous pulley shaft 223. The first transmission belt 230 is sleeved between the driving wheel 221 and another driven wheel 222 located on the opposite side of the frame 210. The second transmission belt 240 is sleeved between the remaining two driven wheels 222.
[0072] For example, both the first transmission belt 230 and the second transmission belt 240 can be high-temperature resistant synchronous belts to reduce damage.
[0073] Reference Figure 1 and Figure 2 As shown, in some embodiments, the first conveying component 200 and the second conveying component 300 are offset in the direction of movement of the third conveying component 420.
[0074] In the above embodiment, the movement direction of the third conveying component 420 can be vertical, and the first conveying component 200 and the second conveying component 300 are offset in the vertical direction. This can avoid interference or friction between the first conveying component 200 and the third conveying component 420 during the process of the steering mechanism 400 transporting the component to be conveyed to the second conveying component 300 in the second state, thereby ensuring the stability of the transport of the component to be conveyed.
[0075] For example, refer to Figure 1 As shown, the second conveying component 300 can be located above the first conveying component 200. Of course, in some other embodiments, the second conveying component 300 can be located below the first conveying component 200, and this application does not impose any restrictions on this.
[0076] Reference Figure 3As shown, in some embodiments, the frame 210 has a first mounting part 211 on each of its opposite sides, and the first mounting part 211 is used to mount the drive wheel assembly 220.
[0077] In the above embodiment, the first mounting part 211 can be formed by extending outward from the frame 210, and is mainly used for rotating and mounting the drive wheel set 220.
[0078] Specifically, refer to Figure 3 As shown, the number of first mounting parts 211 can be four, for rotating the drive wheel 221 and three driven wheels 222 of the drive wheel assembly 220.
[0079] Reference Figure 1 and Figure 2 As shown, in some embodiments, the specific structures of the second conveying component 300 and the third conveying component 420 can be the same as the structure of the first conveying component 200, which will not be described in detail here.
[0080] Reference Figure 1 and Figure 4 As shown, in some embodiments, the telescopic end of the lifting member 410 has a second mounting portion 411 for mounting a third conveying assembly 420.
[0081] In the above embodiment, the second mounting part 411 can be formed by extending outward from the telescopic end of the lifting member 410, mainly used for rotatably mounting the third conveying assembly 420 to ensure the stability of the movement of the third conveying assembly 420.
[0082] Reference Figure 1 and Figure 4 As shown, in some embodiments, a second mounting base 130 is provided on the frame 100, and a second conveying assembly 300 is disposed on the second mounting base 130.
[0083] In the above embodiment, the second mounting base 130 is mainly used to mount the second conveying assembly 300 and to position the second conveying assembly 300 above the first conveying assembly 200.
[0084] Specifically, refer to Figure 4 As shown, the second mounting base 130 can be connected to the frame 210 of the second conveying assembly 300.
[0085] The conveying system provided in this application includes at least two conveying units and the auxiliary conveying structure described above. The conveying units are used to transport items to be conveyed, and the auxiliary conveying structure is disposed between the two conveying units.
[0086] In the auxiliary conveying structure, the two first conveying components 200 are set one-to-one with the two conveying units.
[0087] It is understood that there are at least two conveying units, and the number of conveying units can also be three, four, five, etc., as long as they are set to correspond to the first conveying component 200, the second conveying component 300 and the steering mechanism 400 in the auxiliary conveying structure. This application embodiment does not impose too many restrictions on this.
[0088] In the above structural configuration, since the conveying system adopts the auxiliary conveying structure in the above embodiment, it also has the advantages and benefits brought by the above auxiliary conveying structure, which will not be elaborated further here.
