Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a material conveying device and a string welding machine. Background Art

[0002] In the production of photovoltaic cell strings, there is a laminating process that uses adhesive film to bond the solder ribbons and cell sheets into cell strings.

[0003] The traditional method is to lay the film on the horizontal conveying surface of the conveyor device, and then stack the welding ribbon and battery cells on the film. After the film, welding ribbon and battery cells are stacked, the film is transported to the stringing station for heating, so that the film welding ribbon and battery cells are connected into a battery string.

[0004] However, in this method, it is necessary to place the adhesive film on the horizontal conveying surface of the conveyor first, and the laying of the soldering tape and the battery cells can only be carried out after the adhesive film is laid. This method will cause the production cycle to slow down. Utility Model Content

[0011] The heating device is arranged in the horizontal supporting plate and is used for heating the horizontal supporting plate.

[0012] Compared with using only the horizontal conveying section to complete loading and conveying, setting up the feeding conveying section can load the material onto the conveyor belt in advance, and due to the setting of the adsorption holes, the material can be automatically adsorbed onto the conveyor belt, so that loading, conveying and serial connection do not affect each other and are carried out simultaneously, which significantly improves the efficiency of material conveying and serial connection; in addition, the heating device is set in the horizontal support plate, which can directly heat the material on the horizontal support plate, that is, material conveying and heating are carried out simultaneously, further improving material production efficiency.

[0014] The first end of the transition support plate includes a first arc surface structure, and the transition support plate is connected to the horizontal support plate through the first arc surface structure.

[0015] The feed conveying section supports the conveyor belt by setting a transition support plate, while ensuring the stable transportation of materials in the feed conveying section, and the first end of the transition support plate includes a first arc surface structure, so that the connection between the transition support plate and the horizontal support plate is naturally smooth, which improves the support and stability effect of the conveyor belt and makes the conveyor belt transition smooth at the connection, so that the material can enter the horizontal conveying section more smoothly and stably from the feed conveying section.

[0016] In some embodiments, the transition support plate further includes a second curved surface structure, and the second curved surface structure is disposed at the second end of the transition support plate.

[0017] The transition support plate is provided with a second cambered surface structure, so that the conveyor belt is smooth and stable when entering the transition conveying section, thereby allowing the material to enter the horizontal conveying section more smoothly and stably from the feed conveying section, thereby improving transportation efficiency.

[0029] In some embodiments, the feed support plate is provided with conveyor belt adsorption holes;

[0030] The conveyor belt adsorption holes are set corresponding to the areas on the conveyor belt where no through holes are set.

[0031] The conveyor belt adsorption holes can make the conveyor belt adsorbed on the feed support plate. At this time, the conveyor belt is not easy to fall off, which increases the stability of the conveyor belt.

[0032] In some embodiments, grooves are provided on both the feed support plate and the horizontal support plate, and the negative pressure adsorption holes are arranged in groups in the grooves.

[0033] The arrangement of the grooves can form a cavity between the feed support plate or the horizontal support plate and the conveyor belt, making it easier to adsorb the conveyor belt using the negative pressure adsorption holes.

[0034] In some embodiments, the material conveying device further comprises: a transition support roller;

[0035] The transition support roller is arranged between the feed support plate and the horizontal support plate.

[0036] Since the transition support roller has the function of rolling support, the conveyor belt between the feed support plate and the horizontal support plate is stably supported and moves smoothly, further improving the stability and efficiency of material transportation.

[0042] The driving roller is arranged on the side of the material conveying device away from the feeding conveying section, which avoids the influence of the driving roller on the feeding, which is equivalent to increasing the feeding efficiency. In addition, the upper edge height of the driving roller is less than or equal to the height of the horizontal support plate, so that the conveyor belt mounted on the driving roller will not be separated from the horizontal support plate, ensuring that the conveyor belt can be close to the horizontal support plate.

[0043] In some embodiments, the material conveying device further includes an adjusting roller and a driving device;

The soldering tape feeding device and the battery cell feeding device stack soldering tape and battery cells on the film on the horizontal conveying section, so that the stringing device can string the battery cells to form a battery string.

[0064] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application.

[0065] The present application will be described in detail below through specific embodiments.

[0066] In some embodiments, as Figure 1As shown, the material conveying device includes: a feed conveying section 1, a horizontal conveying section 2, a conveyor belt 3 and a heating device 4, the feed conveying section 1 includes a feed support plate 5, and the horizontal conveying section 2 includes a horizontal support plate 6; the feed conveying section 1 is arranged at the front station of the horizontal conveying section 2, and the first end of the feed conveying section 1 is arranged close to the horizontal conveying section 2; the conveyor belt 3 is mounted on the feed support plate 5 and the horizontal support plate 6, and the feed support plate 5 and the horizontal support plate 6 are both used to support the conveyor belt 3; the feed support plate 5 and the horizontal support plate 6 are both provided with negative pressure adsorption holes, and the conveyor belt 3 is provided with through holes, and the negative pressure adsorption holes are used to adsorb the material to be conveyed on the conveyor belt 3 through the through holes, and the conveyor belt 3 conveys the material from the side of the horizontal support plate 6 to the top of the horizontal support plate 6 through the feed support plate 5; the heating device 4 is arranged in the horizontal support plate 6, and is used to heat the horizontal support plate 6.

[0067] In one implementation, a cavity or pipeline connected to the negative pressure adsorption hole is provided on the feed support plate 5 and the horizontal support plate 6. The cavity or pipeline is connected to the adsorption device, and the adsorption device draws air into the negative pressure adsorption hole through the cavity or pipeline.

[0068] The heating device 4 can be a heating rod, which is mounted on the feed support plate 5 and the horizontal support plate 6 through mounting holes.

[0069] In one implementation, the optional working process of the material conveying device is: the material to be conveyed can be adsorbed onto the conveyor belt 3 at the feed conveying section 1 through the through holes on the conveyor belt 3 and the negative pressure adsorption holes on the feed support plate 5. The material moves driven by the conveyor belt 3, and the conveyor belt 3 transports the material from the side of the horizontal support plate 6 to the top of the horizontal support plate 6 through the feed support plate 5. Then, the heating device 4 arranged in the horizontal support plate 6 can heat the material above the horizontal support plate 6, such as preheating or heating in series.

[0070] In the above embodiment, compared with using only the horizontal conveying section 2 to complete loading and conveying, setting the feeding conveying section 1 can load the material onto the conveyor belt 3 in advance, and due to the setting of the adsorption holes, the material can be automatically adsorbed onto the conveyor belt 3, so that loading, conveying and welding do not affect each other and are carried out simultaneously, which significantly improves the efficiency of material conveying and string welding; in addition, the heating device 4 is arranged in the horizontal support plate 6, and can directly heat the material on the horizontal support plate 6, that is, material conveying and heating are carried out simultaneously, further improving material production efficiency.

[0071] In some optional embodiments, the heating device 4 can be a heating rod, a heating plate, a heating lamp, etc. Exemplarily, the heating device 4 can be a resistance heating rod.

[0072] In some embodiments, as Figure 2As shown, the feed conveying section 1 includes a transition conveying section 7, and the transition conveying section 7 includes a transition support plate 8; the first end of the transition support plate 8 includes a first arc surface structure 9, and the transition support plate 8 is connected to the horizontal support plate 6 through the first arc surface structure 9.

[0073] The optional working process of the material conveying device of the embodiment of the present application is: the material can be first conveyed from the vertical support surface on the transition support plate 8 of the transition conveying section 7 in the feed conveying section 1 to the first curved surface structure 9, and then conveyed from the first curved surface structure 9 to the horizontal conveying section 2. Compared with the material being directly conveyed from the transition support plate 8 to the horizontal support plate 6, the setting of the first curved surface structure 9 makes the connection between the transition support plate 8 and the horizontal support plate 6 naturally smooth, thereby improving the supporting and stabilizing effect of the conveyor belt 3 and making the conveyor belt 3 transition smoothly at the connection, so that the material can enter the horizontal conveying section 2 more smoothly and stably from the feed conveying section 1.

[0074] In one implementation, the transition support plate 8 and the cambered surface mechanism are integrally machined.

[0075] In some embodiments, as Figure 2 As shown, the transition support plate 8 further includes a second curved surface structure 10 , which is disposed at the second end of the transition support plate 8 .

[0076] When the second end of the transition support plate 8 is provided with other components (such as a bottom support plate), the optional working process of the material conveying device of the embodiment of the present application is: the material passes through the bottom support plate, the second curved surface structure 10, the vertical support surface of the transition support plate 8, the first curved surface structure 9 and the horizontal support plate 6 in sequence. The setting of the second curved surface structure 10 makes the conveyor belt 3 smooth and stable when entering the transition conveying section, so that the material can enter the horizontal conveying section 2 more smoothly and stably from the feed conveying section, thereby improving the transportation efficiency.

[0077] In one implementation, the first end of the first curved surface structure 9 is tangent to the vertical support surface of the transition support plate 8, and the second end of the first curved surface structure 9 is tangent to the support surface of the horizontal support plate 6. The first end of the second curved surface structure 10 is tangent to the vertical support surface of the transition support plate 8, and the second end of the second curved surface structure 10 is tangent to the support surface of the bottom support plate 14.

[0078] In some embodiments, as Figure 2 As shown, the transition support plate 8 also includes a first horizontal structure 11 and a second horizontal structure 12; the first horizontal structure is arranged on the outside of the first curved surface structure 9, and the transition support plate 8 is connected with the horizontal support plate 6 through the first curved surface structure 9 and the first horizontal structure 11 in sequence; the second horizontal structure 12 is arranged on the outside of the second curved surface structure 10, and the conveyor belt passes through the second horizontal structure 12 and the second curved surface structure 10 in sequence to move toward the transition support plate 6.

[0079] In one implementation, in order to make the connection between the transition support plate 8 and the horizontal support plate 6 more stable, a first horizontal structure 11 can be set on the outside of the first curved surface structure 9, and the first horizontal structure 11 and the horizontal support plate 6 can be set on the same horizontal plane, so that the transition support plate 8 and the horizontal support plate 6 can better support the conveyor belt 3; similarly, the second horizontal structure 12 is set on the outside of the second curved surface structure 10. When other components (such as a bottom support plate) are provided at the second end of the transition support plate 8, the second horizontal structure 12 and the bottom support plate can be set on the same horizontal plane, so that the transition support plate 8 and the bottom support plate can better support the conveyor belt 3. The conveyor belt 3 is supported. At this time, the optional working process of the material conveying device of the embodiment of the present application is: the material passes through the bottom support plate, the second horizontal structure 12, the second curved surface structure 10, the transition support plate 8, the first curved surface structure 9, the first horizontal structure 10 and the horizontal support plate 6 in sequence. The setting of the first horizontal structure 11 and the second horizontal structure 12 can make the first curved surface 9 of the transition support plate 8 and the horizontal support plate 6 and the feeding point of the second curved surface structure 10 of the transition support plate 8 have a stable support structure, thereby further improving the transportation stability and smoothness of the conveyor belt 3, ensuring the stable and smooth transportation of materials, and thus improving the transportation efficiency.

[0080] In order to avoid installation errors, the transition support plate 8 with the first curved surface structure 9 and the second curved surface structure 10 can be processed in one piece.

[0081] In some embodiments, as Figure 1 and Figure 2 The feed conveying section 1 shown also includes a bottom conveying section 13, which also includes a bottom support plate 14. The bottom conveying section 13 is horizontally arranged below the horizontal conveying section 2. The first end of the transition conveying section 7 is positioned adjacent to the horizontal conveying section 2, and the second end of the transition conveying section 7 is positioned adjacent to the bottom conveying section 13. The second end of the transition support plate 8 is connected to the bottom support plate 14. The bottom support plate 14 is used to support the sliding conveyor belt 3. Negative pressure adsorption holes are also provided on the bottom support plate 14 at positions corresponding to the through holes of the conveyor belt 3. Similarly, a cavity is also provided on the bottom support plate 14, which is connected to the negative pressure adsorption holes. The cavity is connected to an external negative pressure adsorption device to evacuate the negative pressure adsorption holes.

[0082] In one implementation, the negative pressure adsorption device may be a vacuum generator or a blower.

[0083] In one implementation, the bottom conveying section 13 is arranged at the second end of the transition conveying section 7, and the bottom support plate 14 is connected to the second horizontal structure 12 of the transition conveying plate 8 on the same horizontal plane, that is, the conveyor belt 3 is jointly supported by the bottom support plate 14, the transition support plate 8 and the horizontal support plate 6. At this time, the material is conveyed from the bottom support plate 14 to the transition support plate 8, and then to the horizontal support plate 6. The setting of the bottom support plate 14 makes the conveyor belt 3 also have supporting force on the bottom part, which greatly increases the supporting effect on the conveyor belt; at the same time, the bottom conveying section 13 can be used to receive materials, lengthens the area where materials can be laid, and allows materials to directly pass through the transition conveying section 13 into the horizontal conveying section 2 for welding, greatly improving the production efficiency of the battery string.

[0084] In some embodiments, negative pressure adsorption holes are provided on the first curved surface structure 9 , the second curved surface structure 10 , the first horizontal structure 11 , and the second horizontal structure 12 .

[0085] In one implementation, negative pressure adsorption holes are provided on the first curved surface structure 9, the second curved surface structure 10, the first horizontal structure 11 and the second horizontal structure 12, and through holes are provided on the conveyor belt 3. That is to say, the negative pressure adsorption holes and through holes can be used on the first curved surface structure 9, the second curved surface structure 10, the first horizontal structure 11 and the second horizontal structure 12 to adsorb materials on the conveyor belt 3, ensuring that the materials are tightly attached to the conveyor belt 3 when the conveyor belt 3 is conveying, ensuring the stability of the materials during transportation and preventing the materials from shifting during transportation, avoiding affecting the subsequent processing actions of the materials, thereby ensuring the production efficiency of the materials.

[0086] In some embodiments, as Figure 3 As shown, the feed support plate 5 is provided with conveyor belt adsorption holes 15 ; the conveyor belt adsorption holes 15 are provided corresponding to the areas on the conveyor belt 3 where no through holes are provided.

[0087] In one implementation, the feed conveyor plate 5 includes a bottom support plate 14 and a transition support plate 8, both of which are provided with conveyor belt adsorption holes 15. In one implementation, areas of the conveyor belt 3 without through-holes are unable to adsorb materials. Therefore, a plurality of conveyor belt adsorption holes 15 can be evenly distributed in these areas. Providing conveyor belt adsorption holes 15 in these areas allows the conveyor belt 3 to be adsorbed on the transition support plate 8. In this case, the conveyor belt 3 is less likely to shift during material transport, thereby increasing its stability.

[0088] In some embodiments, as Figure 3 and Figure 4 As shown, both the feed support plate 5 and the horizontal support plate 6 are provided with grooves 16 , and the negative pressure adsorption holes are arranged in groups in the grooves 16 .

[0089] In one implementation, a groove 16 is arranged in a strip shape, and the negative pressure adsorption holes are arranged at the bottom of the groove 16 and arranged along the length of the groove 16. A groove 16 can be provided with 2, 3, 4, 5, 6, 7, 8, 9, 10 or more negative pressure adsorption holes.

[0090] In one implementation, the negative pressure adsorption holes are arranged in groups in the groove 16, and the conveyor belt is covered on the groove 16, that is, the setting of the groove 16 can form a cavity between the feed support plate 5, the horizontal support plate 6 and the conveyor belt 3, and a vacuum pump can be used to extract the air in the cavity through the negative pressure adsorption holes and the through holes, so that the air pressure in the cavity is lower than the external atmospheric pressure, so that the conveyor belt 3 and the material can be adsorbed on the feed support plate 5 and the horizontal support plate 6, and the setting of the groove 16 ensures the consistency of the adsorption force of the negative pressure adsorption holes in the same groove 16.

[0091] In some embodiments, as Figure 2-Figure 3 As shown, the material conveying device further includes: a transition support roller 17; the transition support roller 17 is arranged between the feed support plate 5 and the horizontal support plate 6.

[0092] In one implementation, the transition support roller 17 can be a driven roller. When the conveyor belt 3 moves from the feed support plate 5 to the horizontal support plate 6, it can drive the transition support roller 17 to rotate. The setting of the transition support roller 17 converts the friction between the feed support plate 5 and the horizontal support plate 6 and the conveyor belt 3 into rolling friction, reducing the friction loss of the conveyor belt 3. Since the transition support roller 7 has the function of rolling support, the conveyor belt 3 between the feed support plate 5 and the horizontal support plate 6 is stably supported while moving smoothly, further improving the stability and efficiency of material transportation.

[0093] In some embodiments, the transition support roller 17 includes a roller 21 and rollers 22 arranged at intervals. Adsorption blocks 23 are provided between adjacent rollers, and negative pressure adsorption holes are provided on the adsorption blocks 23.

[0094] In one implementation, negative pressure adsorption holes are also provided on the adsorption block 23 of the transition support roller 17. At this time, the vacuum pump can also evacuate the negative pressure adsorption holes on the adsorption block 23, thereby achieving adsorption of the material on the conveyor belt 3, ensuring the stability of the material at the connection between the feed support plate 5 and the horizontal support plate 6, preventing it from displacing at the corner connection, and ensuring the accuracy of material transportation.

[0095] In some embodiments, as Figure 5As shown, the material conveying device includes a driving roller 18 and a driving device 19; the driving roller 18 is arranged on the side of the material conveying device away from the feed conveying section 1, and the upper edge height of the driving roller 18 is less than or equal to the height of the horizontal support plate 6; the conveyor belt 3 is also mounted on the driving roller 18, and the driving end of the driving device 19 is connected to the driving roller 18, and the driving device 19 drives the conveyor belt 3 to rotate through the driving roller 18.

[0096] In one implementation, the driving device 19 drives the driving roller 18 to rotate, and the rotation of the driving roller 18 drives the conveyor belt 3 to rotate on the bottom support plate 14, the transition support plate 8 and the horizontal support plate 6. The driving roller 18 is arranged on the side of the material conveying device away from the feed conveying section 1, avoiding the influence of the driving roller 18 on the feed, which is equivalent to increasing the feeding efficiency. In addition, the upper edge height of the driving roller 18 is less than or equal to the height of the horizontal support plate 6, so that the conveyor belt 3 mounted on the driving roller 18 will not separate from the horizontal support plate 6, ensuring that the conveyor belt 3 can be close to the horizontal support plate 6.

[0097] In some embodiments, as Figure 6 As shown, the material conveying device also includes an adjusting roller 20 and a driving device; the adjusting roller 20 is arranged close to the feed conveying section 1, and the conveyor belt 3 is also sleeved on the adjusting roller 20. The driving device drives the adjusting roller 20 to move to drive the adjustment of the conveyor belt 3.

[0098] In one implementation, the driving device includes a telescopic cylinder or a motor, which drives the adjusting roller 20 to move along the conveying direction of the material conveying device or in a direction opposite to the conveying direction to achieve tensioning or loosening of the conveyor belt 3.

[0099] Alternatively, the driving device is connected to one end of the adjusting roller 20 , and the driving device drives the adjusting roller 20 to swing to achieve deviation correction adjustment of the conveyor belt 3 .

[0100] In one implementation, the conveyor belt 3 may gradually deform during long-term use, causing the length of the conveyor belt 3 to increase and become loose. At this time, the conveyor belt 3 cannot be used normally. The driving device can be used to drive the adjusting roller 20 to change the position of the adjusting roller 20, so that the loose conveyor belt 3 can be tightened again and can continue to be used normally, so that the conveyor belt 3 can stably transport materials and improve transportation efficiency.

[0101] In some embodiments, the material conveying device further includes a serial connection device; the serial connection device is embedded in the horizontal conveying section 2 , and the top surface of the serial connection device is coplanar with the top surface of the horizontal support plate 6 .

[0102] In one implementation, the top surface of the serial connection device is arranged coplanar with the top surface of the horizontal support plate 6. When the material is transported to the horizontal support plate 6, the serial connection device can connect the material on the horizontal support plate 6 in series. The heating device can be used to preheat the material during the transportation process, thereby increasing the serial connection efficiency of the material.

[0103] In one implementation, the serial connection device can be one of infrared, hot air, and light curing serial connection.

[0104] In some embodiments, the present application provides a material stringer, comprising any one of the material conveying devices in the above embodiments, and the stringer also includes a film feeding device, a solder tape feeding device, and a battery cell feeding device. The film feeding device is used to provide film to the feeding and conveying section of the material conveying device, and the conveyor belt is used to drive the film to move to the horizontal conveying section 2. The solder tape feeding device and the battery cell feeding device are used to stack solder tapes and battery cells on the film on the horizontal conveying section 2.

[0105] In one implementation, the negative pressure adsorption holes on the bottom support plate 14 and the transition support plate 8, as well as the through holes on the conveyor belt 3, can be used to adsorb the film provided by the film feeding device onto the conveyor belt 3, and the film can be conveyed from the feed conveying section 1 to the horizontal conveying section 2. At this time, the soldering tape feeding device and the battery cell feeding device stack the soldering tape and the battery cell on the film on the horizontal conveying section 2, and then the serial connection device connects the film, soldering tape and the battery cell in series to form a battery string. Since the film is laid in advance, the soldering tape and the battery cell can be placed directly on the pre-laid film and preheated at the same time, which greatly increases the production efficiency of the battery string and the material transportation efficiency.
