Description

Technical Field

[0001] This application relates to the field of photovoltaic cell string technology, and in particular to a material conveying equipment and a feeding system. Background Technology

[0002] In the production of photovoltaic cell strings, there is a coating process that uses an adhesive film to bond the solder ribbon and the cell to form a cell string.

[0003] The traditional method involves pre-preparing the adhesive film, then using a robotic arm to drive an adsorption plate to lay the pre-prepared adhesive film on the horizontal conveying surface of the conveying device. Then, welding ribbons and battery cells are stacked on the adhesive film. After the adhesive film, welding ribbons, and battery cells are stacked, the adhesive film is conveyed to the series connection station for heating, so that the adhesive film, welding ribbons, and battery cells are connected to form a battery string.

[0004] However, in this method, the action of the robotic arm driving the adsorption plate to adsorb and transfer the adhesive film is discontinuous, resulting in low transfer efficiency. This method will lead to a decrease in the production efficiency of battery strings.

[0005] Similarly, in other material handling fields, robotic arms are often used for material handling, resulting in low material handling efficiency. Therefore, there is an urgent need for a material handling equipment that can improve material handling efficiency. Summary of the Invention

[0006] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a material conveying device to improve material conveying efficiency.

[0007] In a first aspect, this application provides a material conveying device, comprising: a first conveying device, a second conveying device, a first driving device, and a second driving device; the output end of the first driving device is connected to the first conveying device, and the first driving device is used to drive the first conveying device to convey materials; the output end of the second driving device is connected to the second conveying device, and the second conveying device is used to drive the second conveying device to convey materials; the first conveying device is close to the second conveying device, and the first conveying device is disposed below or to one side of the second conveying device; the first conveying device is used to convey materials to a loading station, and the first conveying device is provided with a first negative pressure adsorption hole for adsorbing materials; at least the loading station in the first conveying device is opposite to the second conveying device; the second conveying device is used to adsorb and convey materials at the loading station, and the second conveying device is provided with a second negative pressure adsorption hole for adsorbing materials from the first conveying device onto the second conveying device when the materials are conveyed to the loading station.

[0008] The first conveying device can use the first negative pressure adsorption hole to suck up the material and, driven by the first driving device, convey the material to the loading station. At this time, the second negative pressure adsorption hole on the second conveying device can adsorb the material from the first conveying device to the second conveying device. That is, with the cooperation of the first negative pressure adsorption hole and the second negative pressure adsorption hole, the material can be automatically and continuously conveyed from the first conveyor belt to the second conveyor belt, so that the material can be pre-laid on the second conveying device in advance, which is convenient for subsequent production and thus improves production efficiency.

[0009] In some embodiments, the first conveying device further includes an air blowing hole, which is disposed at the loading station of the first conveying device, and the air blowing hole outputs gas to blow the material located at the loading station from the first conveying device to the second conveying device.

[0010] The air blowing hole can blow the material from the loading station of the first conveying device to the second conveying device. Compared with only using the second negative pressure adsorption hole to adsorb the material from the loading station of the first conveying device to the second conveying device, the air blowing hole can provide thrust for the material. The second negative pressure adsorption hole can more easily adsorb the material to the second conveying device. That is, the air blowing hole further increases the conveying efficiency of the material from the first conveying device to the second conveying device.

[0011] In some embodiments, the first conveying device includes a first conveyor belt and a first support plate; the first support plate is disposed inside the first conveyor belt and is used to support the conveying surface of the first conveyor belt; a first through hole is provided on the first conveyor belt, and a first negative pressure adsorption hole is disposed on the first support plate; the first negative pressure adsorption hole is used to adsorb material onto the first conveyor belt through the first through hole.

[0012] The first conveying device consists of a first conveyor belt and a first support plate. The first support plate is provided with a first negative pressure adsorption hole, and the first conveyor belt is provided with a first through hole. The first negative pressure adsorption hole can adsorb the material onto the first conveyor belt through the first through hole, which increases the stability of the material on the first conveyor belt. The first support plate can also support the first conveyor belt, which increases the flatness of the support surface of the first conveyor belt and the stability of the conveying.

[0013] In some embodiments, the first conveying device further includes a first driving roller and a first driven roller; the output end of the first driving device is connected to the first driving roller, the first driving roller is used to drive the first conveyor belt; the first driven roller is used to roll and support the first conveyor belt under the drive of the first driving roller.

[0014] The first drive roller provides power to the first conveying device, and the first driven roller not only increases the smoothness of material conveying on the first conveyor belt, but also provides support for the first conveyor belt and increases its stability.

[0015] In some embodiments, the first conveying device further includes a position sensor, which is located at the station before the loading station. The position sensor detects the material conveyed to the sensing position of the position sensor, and the first driving device adjusts the feeding distance to the loading station according to the detection result of the position sensor.

[0016] The position sensor is installed at the station before the loading station. It can detect the material at the sensing position and adjust the feeding distance of the material to the loading station based on the detection result, so as to ensure that the material on the first conveyor belt can be accurately transported to the loading station.

[0017] In some embodiments, the second conveying device includes a second conveyor belt and a second support plate; the second support plate is disposed inside the second conveyor belt, and the second support plate is used to support the second conveyor belt; a second through hole is provided on the second conveyor belt, and a second negative pressure adsorption hole is disposed on the second support plate; the second negative pressure adsorption hole is used to adsorb material onto the second conveyor belt through the second through hole.

[0018] The second conveying device consists of a second conveyor belt and a second support plate. The second support plate is provided with a second negative pressure adsorption hole, and the second conveyor belt is provided with a second through hole. The second negative pressure adsorption hole can adsorb the material onto the second conveyor belt through the second through hole, which increases the stability of the material on the second conveyor belt. The second support plate can support the second conveyor belt, which also increases the stability of the second conveyor belt.

[0019] In some embodiments, the second conveying device further includes a second drive roller and a second support member; the output end of the second drive device is connected to the second drive roller, which is used to drive the second conveyor belt; the second support member is used to support the second conveyor belt under the drive of the second drive roller.

[0020] The second drive roller provides power to the second conveying device, and the second support not only increases the smoothness of material conveying on the second conveyor belt, but also provides support for the second conveyor belt and increases its stability.

[0021] In some embodiments, the second conveying device further includes a horizontal support plate and a heating device. The second support plate is disposed at the preceding station of the horizontal support plate. A second conveyor belt is fitted onto the second support plate and the horizontal support plate, both of which support the second conveyor belt. Each horizontal support plate is provided with a third negative pressure adsorption hole, which is used to adsorb the material to be conveyed on the second conveyor belt through the second through hole. The second conveyor belt conveys the material from the side of the horizontal support plate to the top of the horizontal support plate through the second support plate. The heating device is disposed inside the horizontal support plate and is used to heat the horizontal support plate.

[0022] The horizontal support plate further enhances the support effect of the second conveyor belt during horizontal transport. By setting the horizontal support plate, the conveyor belt can support the processed items during horizontal transport, thereby increasing the stability of the second conveyor belt. The third adsorption hole allows the horizontal support plate to also adsorb materials, further improving the stability of the materials on the second conveyor belt and ensuring that the items are in an adsorbed state in real time. This effectively completes the accurate transfer of items from the second support plate to the horizontal support plate when the conveyor belt carries them. The heating device can heat the horizontal support plate.

[0023] In some embodiments, the second support plate includes a vertical support plate and a bottom support plate; the first end of the bottom support plate is disposed close to the first end of the vertical support plate, and the second end of the vertical support plate is disposed close to the end of the horizontal support plate. The bottom support plate adsorbs the material at the loading station onto the second conveyor belt, and the second conveyor belt drives the material to be transported from the vertical support plate to the horizontal support plate.

[0024] The second support plate is defined as including a vertical support plate and a bottom support plate. Multiple support plates can support the second conveyor belt at various positions, further improving the stability of the conveyor belt. The bottom support plate realizes the receiving of materials, and the vertical support plate realizes that the materials adsorbed on the second conveyor belt by the bottom support plate are adsorbed by the vertical support plate and transferred to the horizontal support plate.

[0025] In some embodiments, the thickness of the second conveying device is greater than that of the first conveying device.

[0026] The first conveying device performs fewer functions than the second conveying device. The thickness of the first conveying device is smaller than that of the second conveying device, which can reduce the thickness of the entire material conveying equipment and feeding system, and reduce space occupation.

[0027] In some embodiments, the material is an adhesive film, and the number of adhesive films is multiple.

[0028] Multiple films can be conveyed sequentially to the second conveying device, which is equivalent to laying the films in an orderly manner on the second conveying device in advance, increasing the production efficiency of subsequent battery string production.

[0029] In a second aspect, this application provides a feeding system, including: a material conveying device, a material cutting platform, and a material handling device; the material cutting platform is located at the upstream station of the material handling device and is used to cut the material; the material handling device is located at the upstream station of a first conveying device and is used to transport the cut material to the first conveying device.

[0030] The material cutting platform first cuts the material, and then the material handling device transports the cut material to the first conveying device. This feeding system can realize the automated cutting and handling of materials, which significantly improves the feeding efficiency.

[0031] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0040] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

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

[0042] In some embodiments, such as Figures 1-4 As shown, the material conveying equipment includes: a first conveying device 1, a second conveying device 2, a first driving device (not shown in the figure), and a second driving device (not shown in the figure); the output end of the first driving device is connected to the first conveying device 1, and the first driving device is used to drive the first conveying device 1 to convey material 15; the output end of the second driving device is connected to the second conveying device 2, and the second driving device is used to drive the second conveying device 2 to convey material 15; the first conveying device 1 is close to the second conveying device 2 and is located below the second conveying device 2 (see figure). Figure 1 ) or one side (see Figure 4 The first conveying device 1 is used to convey material 15 to the loading station 3. The first conveying device 1 is provided with a first negative pressure adsorption hole 16, which is used to adsorb material 15. At least the loading station 3 in the first conveying device 1 is opposite to the second conveying device 2. The second conveying device 2 is used to adsorb and convey material 15 at the loading station 3. The second conveying device 2 is provided with a second negative pressure adsorption hole 17, which is used to adsorb material 15 from the first conveying device 1 to the second conveying device 2 when material 15 is conveyed to the loading station 3.

[0043] As mentioned above, the first conveying device 1 is located below or to one side of the second conveying device 2.

[0044] like Figures 1-3The diagram shows a first conveying device 1 positioned below a second conveying device 2. A first support plate 5 is horizontally positioned on the upper surface of the first conveying device 1. A bottom support plate 19 is positioned opposite the first support plate 5 on the lower surface of the second conveying device 2. A vertical support plate 18 is positioned on the side of the second conveying device 2. A horizontal support plate 9 is positioned on the upper surface of the second conveying device 2. A heating device is positioned on the horizontal support plate 9. A position sensor 14 is positioned at the station before the loading station 3 in the first conveying device 1, meaning the position sensor is positioned along the path of the material being conveyed to the loading station. Specifically, the position sensor 14 can be positioned on the first support plate 5, or it can be positioned on the side or above the conveying surface of the first conveying device 1, mounted on the frame or the first support plate 5 of the first conveying device 1 via a connecting frame. Negative pressure adsorption holes are provided on the first support plate 5, the horizontal support plate 9, the vertical support plate 18, and the bottom support plate 19. The optional operating process of the material conveying equipment is as follows: the first negative pressure adsorption hole 16 on the first support plate 5 adsorbs the material 15 onto the first conveying device 1. When the first driving device drives the first conveying device 1 to convey the material 15 to the loading station 3, the second negative pressure adsorption hole 17 on the bottom support plate 19 adsorbs the material 15 from the loading station 3 on the first conveying device 1 onto the second conveying device 2. The second driving device drives the second conveying device 2 to convey the material 15 to a preset position. In one implementation, the adsorption force of the second negative pressure adsorption hole 17 is greater than the adsorption force of the first negative pressure adsorption hole 16. Alternatively, when the first conveying device 1 conveys the material 15 to the loading station 3, the first negative pressure adsorption hole stops adsorbing, and the second negative pressure adsorption hole 17 adsorbs the material 15 from the loading station 3 on the first conveying device 1 onto the second conveying device 2.

[0045] In one implementation, the first support plate 5 can be multiple plates arranged sequentially along the conveying direction. The first support plate 5 located at the loading station 3 can be controlled independently. When the material 15 is conveyed to the loading station 3, the first negative pressure adsorption hole located at the loading station 3 stops adsorption, thereby causing the second negative pressure adsorption hole to adsorb the material 15 onto the second conveying device 2.

[0046] In one implementation, the feeding station 3 can carry one, two, three, four, five, six or more materials 15 at a time. The second negative pressure adsorption hole 17 is used to adsorb the materials 15 at the feeding station 3 from the first conveying device 1 to the second conveying device 2 at the same time when the materials 15 are conveyed to the feeding station 3.

[0047] like Figure 4 This illustrates a configuration where the first conveying device 1 is positioned on one side of the second conveying device 2, wherein... Figure 4The structure in this example lacks a bottom support plate 19, and the first support plate 5 is vertically positioned on one side of the first conveying device 5, corresponding to the vertical support plate 18. The heating device, negative pressure adsorption holes, position sensors, etc., are similar to the aforementioned structure. In this case, the optional operating process of the material conveying equipment is as follows: the first negative pressure adsorption hole 16 on the first support plate 5 adsorbs the material 15 onto the first conveying device 1; when the first drive device drives the first conveying device 1 to convey the material 15 from the first conveying device 1 to the loading station 3, the second negative pressure adsorption hole 17 on the vertical support plate 18 adsorbs the material 15 from the loading station 3 on the first conveying device 1 onto the second conveying device 2; the second drive device drives the second conveying device 2 to convey the material 15 to a preset position.

[0048] It should be noted that the side of the second conveying device 2 should not be set too high, otherwise the thickness of the second conveying device 2 will be too thick. Therefore, when conveying one, two or three materials 15 on the first conveying device 1, the first conveying device 1 can be set on one side of the second conveying device 2. When the first conveying device 1 is set below the second conveying device 2, the feeding requirements of one, two, three, four, five, six, seven or more materials 15 can be met. If space occupation or other conditions are not considered, the above two material conveying devices can be selected according to the actual use. In the above embodiment, the first conveying device 1 can use the first negative pressure adsorption hole 16 to hold the material 15 and, driven by the first driving device, convey the material 15 to the loading station 3. At this time, the second negative pressure adsorption hole 17 on the second conveying device 2 can adsorb the material 15 from the first conveying device 1 to the second conveying device 2. That is, with the cooperation of the first negative pressure adsorption hole 16 and the second negative pressure adsorption hole 17, the material 15 can be automatically conveyed from the first conveying device 1 to the second conveying device 2. When the material conveying equipment is applied to the field of battery string production, the material 15 can be a film. The film can be conveyed from the first conveying device 1 to the second conveying device 2. Afterwards, battery string production can be carried out directly. However, using a robotic arm requires transporting the adhesive film to the second conveying device 2 before battery string production can proceed. Adhesive film transportation and battery string production cannot be carried out simultaneously. Moreover, in order to ensure the integrity of the adhesive film, the traditional robotic arm often needs to use an adsorption plate to adsorb the adhesive film. When placing the adhesive film, the adsorption plate is above the adhesive film, and the robotic arm that moves the adsorption plate needs to occupy a large space above the adhesive film or on the side of the adhesive film away from the second conveying device 2. The material supply occupies a large space. Therefore, the material conveying equipment in this embodiment increases the conveying efficiency of the adhesive film and the battery string production efficiency, and reduces the space occupied during the transfer of the adhesive film.

[0049] Meanwhile, by placing the first conveyor 1 below the second conveyor 2, the space below the second conveyor 2 can be utilized more efficiently. The first conveyor 1 can also pre-store the material 15, enabling continuous and batch feeding of the material 15.

[0050] In some embodiments, the first conveying device 1 further includes an air blowing hole, which is disposed at the loading station 3 of the first conveying device 1. The air blowing hole outputs gas to blow the material 15 located at the loading station 3 from the first conveying device 1 to the second conveying device 2.

[0051] In one implementation, the feeding station 3 can be equipped with both an air blowing hole and a first negative pressure adsorption hole.

[0052] The air blowing hole and the first negative pressure adsorption hole 16 can be the same hole or different holes. When the air blowing hole and the first negative pressure adsorption hole are different adsorption holes, they are connected to the external pneumatic device through different air passages. The air blowing device can be set at the loading station 3, and the air suction device can be set at other locations besides the loading station 3.

[0053] In one implementation, the optional operating process of the material conveying equipment is as follows: the first negative pressure adsorption hole 16 on the first conveying device 1 adsorbs the material 15 onto the first conveying device 1; the first driving device drives the first conveying device 1 to convey the material 15 on the first conveying device 1 to the loading station 3; at this time, the first negative pressure adsorption hole 16 on the first conveying device 1 stops adsorbing the material 15; the air blowing hole on the first conveying device 1 blows the material 15 from the loading station 3 to the second conveying device 2; simultaneously, the second negative pressure adsorption hole 17 on the second conveying device 2 adsorbs the material 15 onto the second conveying device 2; the second driving device drives the second conveying device 2 to convey the material 15 to the preset position. Compared to only using the second negative pressure adsorption hole 17 to adsorb the material 15 from the loading station 3 of the first conveying device 1 to the second conveying device 2, the setting of the air blowing hole can further increase the conveying efficiency of the material 15 from the first conveying device 1 to the second conveying device 2.

[0054] In some embodiments, such as Figures 1-2 As shown, the first conveying device 1 includes a first conveyor belt 4 and a first support plate 5; the first support plate 5 is disposed on the inner side of the first conveyor belt 4 and is used to support the conveying surface of the first conveyor belt 4; a first through hole is provided on the first conveyor belt 4, and a first negative pressure adsorption hole 16 is disposed on the first support plate 5; the first negative pressure adsorption hole 16 is used to adsorb the material 15 onto the first conveyor belt 4 through the first through hole.

[0055] In one implementation, a first negative pressure adsorption hole 16 is disposed on a first support plate 5, and a first conveyor belt 4 is disposed close to the outer side of the first support plate 5. The first conveyor belt 4 covers one end of the first negative pressure adsorption hole 16, forming a cavity. By using an air pump to extract air from the cavity through the other end of the first negative pressure adsorption hole 16, a negative pressure is formed, which adsorbs the first conveyor belt 4 onto the first support plate 5, increasing the stability of the first conveyor belt 4 on the first support plate 5. When the first conveyor belt 4 moves on the first support plate 5, and the first through hole on the first conveyor belt 4 overlaps with the position of the first negative pressure adsorption hole 16 on the first support plate 5, the material 15 can be adsorbed onto the first conveyor belt 4 through the first through hole, increasing the stability of the material 15 on the first conveyor belt 4.

[0056] In some embodiments, such as Figure 1 As shown, the first conveying device 1 also includes a first driving roller 6 and a first driven roller 7; the output end of the first driving device is connected to the first driving roller 6, and the first driving roller 6 is used to drive the first conveyor belt 4; the first driven roller 7 is used to roll and support the first conveyor belt 4 under the drive of the first driving roller 6.

[0057] In one implementation, the first drive roller 6 provides driving force to the first conveying device 1, driving the first conveyor belt 4 to convey material 15. The first driven roller 7 rotates under the drive of the first conveyor belt 4, which not only provides support for the first conveyor belt 4, but also reduces the frictional loss of the first conveyor belt 4.

[0058] In some embodiments, the first conveying device 1 further includes a position sensor 14, which is located at the station before the loading station 3. The position sensor 14 detects the material 15 conveyed to the sensing position of the position sensor 14, and the first driving device adjusts the feeding distance of the material to the loading station 3 according to the detection result of the position sensor 14.

[0059] In one implementation, the position sensor 14 can be a photoelectric sensor, ultrasonic sensor, or other sensor capable of sensing position.

[0060] In one implementation, the first conveying device 1 may operate as follows: the position sensor 14 detects the position of the material 15 on the first conveyor belt 4, and the first driving device determines the feeding distance of the material 15 based on the position of the material 15 on the first conveyor belt 4 and the position of the loading station 3, and conveys the material 15 to the loading station 3 according to the feeding distance. The setting of the position sensor 14 ensures that the material 15 on the first conveyor belt 4 can be accurately transported to the loading station 3.

[0061] In some embodiments, such as Figures 1-3As shown, the second conveying device 2 includes a second conveyor belt 8 and a second support plate (the vertical support plate 18 and the bottom support plate 19 in the figure are both second support plates); the second support plate is disposed on the inner side of the second conveyor belt 8 and is used to support the second conveyor belt 8; a second through hole is provided on the second conveyor belt 8, and a second negative pressure adsorption hole 17 is disposed on the second support plate; the second negative pressure adsorption hole 17 is used to adsorb the material 15 onto the second conveyor belt 8 through the second through hole.

[0062] In one implementation, the second negative pressure adsorption hole 17 is disposed on the second support plate, and the second conveyor belt 8 is disposed close to the outer side of the second support plate. The second conveyor belt 8 covers one end of the second negative pressure adsorption hole 17, forming a cavity. The air pump extracts the air in the cavity through the other end of the first negative pressure adsorption hole 16, thereby creating a negative pressure that adsorbs the second conveyor belt 8 onto the second support plate, increasing the stability of the second conveyor belt 8 on the second support plate. When the second conveyor belt 8 moves on the second support plate, and the second through hole on the second conveyor belt 8 overlaps with the position of the second negative pressure adsorption hole 17 on the second support plate, the material 15 can be adsorbed onto the second conveyor belt 8 through the second through hole, increasing the stability of the material 15 on the second conveyor belt 8.

[0063] In some embodiments, such as Figure 1 As shown, the second conveying device 2 also includes a second drive roller 10 and a second support member; the output end of the second drive device is connected to the second drive roller 10, and the second drive roller 10 is used to drive the second conveyor belt 8; the second support member is used to support the second conveyor belt 8 under the drive of the second drive roller 10.

[0064] In one implementation, the second support member can be a second driven roller or a second support plate. The second drive roller 10 provides driving force to the second conveying device 2, driving the second conveyor belt 8 to convey material 15. When the second support member is a second support plate, it provides support for the second conveyor belt 8; when it is a second driven roller, it rotates under the drive of the second conveyor belt 8, providing support for the second conveyor belt 8 and reducing frictional loss. In one implementation, the second driven roller can be provided with negative pressure adsorption holes, and an air passage connected to the negative pressure adsorption holes is provided in the center of the roller. The roller can support the conveyor belt while simultaneously conveying the material carried on it. Of course, the second conveying device can also include other support rollers for conveyor belt tensioning, etc., which will not be elaborated here.

[0065] In some embodiments, the second conveying device 2 further includes a horizontal support plate 9 and a heating device. The second support plate is disposed at the front station of the horizontal support plate 9. The second conveyor belt 8 is fitted onto the second support plate and the horizontal support plate 9, and both the second support plate and the horizontal support plate 9 are used to support the second conveyor belt 8. The horizontal support plate 9 is provided with a third negative pressure adsorption hole, which is used to adsorb the material 15 to be conveyed on the second conveyor belt 8 through the second through hole. The second conveyor belt 8 conveys the material 15 from the side of the horizontal support plate 9 to the top of the horizontal support plate 9 through the second support plate. The heating device is disposed inside the horizontal support plate 9 and is used to heat the horizontal support plate 9.

[0066] In some alternative embodiments, the heating device may be a heating rod, a heating plate, a heating lamp, etc. For example, the heating device may be a resistance heating rod, which is mounted on the horizontal support plate 9 through mounting holes.

[0067] In one implementation, the second support plate is set on the horizontal support plate 9 along the feeding direction of the material conveying direction. The optional working process of the second conveying device 2 is as follows: the second negative pressure adsorption hole 17 on the second support plate adsorbs the material 15 from the loading station 3 onto the second conveyor belt 8. The second driving device drives the second conveyor belt 8 to transport the material 15 from the second support plate to the horizontal support plate 9. The third negative pressure adsorption hole on the horizontal support plate 9 adsorbs the material 15 onto the second conveyor belt 8. At this time, the heating device heats the horizontal support plate 9, which can realize the heating of the material 15 on the horizontal support plate 9. Since the heating device is set below the horizontal support plate 9, it can directly heat the horizontal support plate 9. It is equivalent to the material 15 being preheated after being transported to the horizontal support plate 9, which greatly increases the subsequent connection efficiency of the material 15.

[0068] In some embodiments, such as Figure 1 As shown, the second support plate includes a vertical support plate 18 and a bottom support plate 19; the first end of the bottom support plate 19 is close to the first end of the vertical support plate 18, and the second end of the vertical support plate 18 is close to the end of the horizontal support plate 9. The bottom support plate 19 adsorbs the material 15 at the loading station 3 onto the second conveyor belt 8, and the second conveyor belt 8 drives the material 15 to be transported from the vertical support plate 18 to the horizontal support plate 9.

[0069] To make the connection between the bottom support plate 19 and the vertical support plate 18 smoother, the first end of the bottom support plate 19 or the first end of the vertical support plate 18 is provided with an arc surface, and the arc surface is also provided with a second negative pressure adsorption hole. On the one hand, it can realize the connection and conveying of material 15, and on the other hand, it can also realize the smooth support of the second conveyor belt 8.

[0070] The second end of the vertical support plate 18 can also be provided with an arc surface, and the arc surface is also provided with a second negative pressure adsorption hole, which can realize the connection and conveying of material 15 on the one hand, and also realize the smooth support of the second conveyor belt 8 on the other hand.

[0071] Of course, in optional embodiments, support rollers or wheels can be provided at both ends of the vertical support plate 18 to make the conveying of the second conveyor belt 8 smoother.

[0072] In one implementation, both the vertical support plate 18 and the bottom support plate 19 are provided with second negative pressure adsorption holes 17. The material 15 is adsorbed onto the second conveyor belt 8 at the feeding station 3 and then conveyed to the horizontal support plate 9 via the bottom support plate 19 and the vertical support plate 18. That is, the second conveyor belt 8 is mounted on multiple support plates. Multiple support plates can increase the support effect on the second conveyor belt 8 and increase the stability of the second conveyor belt 8. In addition, each support plate is provided with negative pressure adsorption holes, which also increases the stability of the material 15 on the second conveyor belt 8.

[0073] In some embodiments, the thickness of the second conveying device 2 is greater than that of the first conveying device 1.

[0074] That is, the distance between the upper and lower surfaces of the second conveying device 2 is greater than the distance between the upper and lower surfaces of the first conveying device 1.

[0075] In some embodiments, material 15 is an adhesive film, and the number of adhesive films is multiple.

[0076] In one implementation, when the material conveying equipment is applied to the battery string production field, multiple films can be conveyed sequentially, in batches or one by one, to the second conveying device through the first conveying device 1. This is equivalent to laying the films in an orderly manner on the second conveying device 2 in advance, which increases the production efficiency of subsequent battery string production.

[0077] In some embodiments, such as Figure 5 As shown, a feeding system is provided, including: a material conveying device, a material cutting platform 12 and a material handling device 13; the material cutting platform 12 is set at the front station of the material handling device 13, and the material cutting platform 12 is used to cut the material 15; the material handling device 13 is set at the front station of the first conveying device 1, and the material handling device 13 is used to transport the cut material 15 to the first conveying device 1.

[0078] In one implementation, the optional operating mode of the feeding system is as follows: the material cutting platform 12 first cuts the material 15, and after cutting, the material handling device 13 transports the cut material 15 to the first conveying device 1. The first conveying device 1 then transports the material 15 to the second conveying device 2, and the heating device preheats the material 15. This feeding system can realize the automated cutting and handling of the material 15, which significantly improves the feeding efficiency and further improves the production efficiency of the battery string.

[0079] The material cutting platform 12 is a device capable of cutting large pieces of material 15. Specifically, the material cutting platform 12 may include a material platform and a cutting blade. After the large pieces of material 15 are laid on the material platform, the cutting blade falls down, thereby cutting the large pieces of material 15 into smaller pieces. The material handling device 13 is a device capable of conveying the cut pieces of material 15 to the first conveying device 1. Specifically, the material handling device 13 may be a robotic arm equipped with suction cups or clamps to pick up the material 15 from the material cutting platform 12 and convey it to the first conveying device 1. The material handling device 13 may also be a handling device with a conveyor belt, which may also have negative pressure suction holes. The material 15 is picked up from the material cutting platform 12 through the negative pressure suction holes and transported to the first conveying device 1.

[0080] Corresponding to the above-mentioned equipment and system, this application provides a specific application scenario, namely, a battery string production scenario: The material cutting platform 12 cuts large pieces of adhesive film into smaller pieces. The material handling device 13 sequentially picks up the smaller pieces of adhesive film from the material cutting platform 12 and transports them to the first end of the first conveying device 1. The first conveying device 1 transports the smaller pieces of adhesive film to the loading station 3 at the second end of the first conveying device 1. The second negative pressure adsorption hole 17 on the second conveying device 2 adsorbs the smaller pieces of adhesive film at the loading station 3 onto the second conveying device 2. The second conveying device 2 then transports the smaller pieces of adhesive film to the horizontal support plate 9. At this time, batteries can be placed on the adhesive film. The horizontal support plate 9 is heated by a heating device, and the heat on the horizontal support plate 9 can be transferred to the adhesive film, thereby completing the production of the battery string. Since the adhesive film is pre-cut and finally laid on the horizontal support plate 9, it is only necessary to place batteries on the adhesive film on the horizontal support plate 9 to complete the production of the battery string, which greatly increases the production efficiency of the battery string.

[0081] Meanwhile, the setting of the first conveying device 1 makes the feeding of the second conveying device 2 more flexible, and the feeding can be completed in advance on the bottom surface of the second conveying device 2, avoiding interference with other components.
