Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell production technology, and more specifically, to a feeding device and a conveying production line. Background Technology

[0002] In the photovoltaic cell production process, the conveying of plate-shaped materials usually requires the use of robotic arms for feeding and unloading. Due to site or equipment configuration reasons, the feeding and unloading direction of plate-shaped materials in horizontal conveying equipment needs to be carried out on the side of the conveying equipment (the side perpendicular to the conveying direction).

[0003] Currently, the feeding and unloading units in the above-mentioned situations mostly adopt a large roller design, which makes it easy for the robotic arm to pick up and place plate-shaped materials in the gap between the rollers. That is, both feeding and unloading require the plate-shaped materials to be rotated 90 degrees. This design of the mechanism will result in a longer production cycle time and affect the production capacity. Utility Model Content

[0004] One objective of this invention is to provide a feeding / discharging device and a conveying production line.

[0005] According to a first aspect of the present invention, a feeding device is provided for use with plate-shaped materials, comprising:

[0006] A plurality of first rolling elements are arranged side by side along a first direction;

[0007] A plurality of second rolling elements, each having a first position and a second position, wherein when the plurality of second rolling elements are in the first position, they are respectively arranged side by side with the plurality of first rolling elements along the first direction to form a transmission plane; and when the plurality of second rolling elements are in the second position, the plurality of second rolling elements disengage from the transmission plane.

[0008] A first driving member is configured to drive a plurality of first rolling members to rotate, so that the plate-shaped material on the transfer plane can move along the first direction.

[0009] A second drive member is configured to drive a plurality of second rolling elements to move to the first position and the second position.

[0010] Optionally, the second position is located below the first position, and there is a set distance between the second position and the first position.

[0011] Optionally, the plurality of second scroll elements are divided into an array, and the array of second scroll elements are located at different positions of the plurality of first scroll elements.

[0012] Optionally, it also includes:

[0013] The first bracket, in which multiple first rolling elements are movably mounted, and are respectively connected to the output end of the first driving element through a transmission element;

[0014] The second bracket has multiple second rolling elements fixedly assembled thereon, and the output end of the second drive element is connected to the second bracket.

[0015] Optionally, the first rolling element includes a roller and a plurality of first rollers coaxially and spaced apart along the axial direction of the roller, the two ends of the roller being rotatably mounted on the first bracket, and the axial direction of the roller being perpendicular to the first direction;

[0016] The second rolling element includes a fixed shaft and a plurality of second rollers rotatably mounted on the fixed shaft. The two ends of the fixed shaft are fixed to the first bracket, and the axial direction of the fixed shaft is perpendicular to the first direction.

[0017] Optionally, the transmission component is a transmission rod, which is rotatably mounted on the first bracket along the first direction, and the transmission rod is connected to the ends of the first driving component and the plurality of rollers respectively via gear transmission.

[0018] Optionally, the second driving component is a cylinder or an electric motor.

[0019] According to a second aspect of the present invention, a conveyor production line is provided, comprising:

[0020] The conveying device and the feeding / discharging device described in the first aspect;

[0021] The conveying device is connected to the infeeding device and can move the plate-shaped material on the conveying plane along the first direction to a set position.

[0022] Optionally, the transmission device includes:

[0023] A plurality of third rolling elements are arranged side by side with a plurality of first rolling elements along the first direction to form the transmission plane;

[0024] A third driving member is configured to drive a plurality of the third rolling members to rotate, thereby moving the plate-shaped material on the transmission plane to the set position.

[0025] Optionally, it also includes a material handling device, which can handle material handling at the first position when the plurality of second rolling elements are in the second position.

[0026] One technical advantage of this invention is that by setting up multiple second rolling elements and a second driving element for driving the multiple second rolling elements, when the multiple second rolling elements are in the first position, they can form a transmission plane with the multiple first rolling elements to realize the conveying of plate-shaped materials. When the second driving element drives the multiple second rolling elements to move to the second position, the space formed in the first position can avoid the equipment used for picking up and putting down plate-shaped materials. This achieves the purpose of directly feeding and discharging from the side of the feeding and discharging device without adjusting the direction of the plate-shaped materials, shortening the production cycle and increasing the production capacity.

[0045] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0046] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0047] like Figure 1As shown, according to a first aspect of the present invention, a feeding device 100 is provided, applied to a plate-shaped material 400, including a plurality of first rolling elements 1, a plurality of second rolling elements 2, a first driving element 3, and a second driving element 4. The plurality of first rolling elements 1 are arranged side by side along a first direction; the plurality of second rolling elements 2 each have a first position and a second position. When the plurality of second rolling elements 2 are in the first position, they are arranged side by side with the plurality of first rolling elements 1 along the first direction to form a transmission plane. When the plurality of second rolling elements 2 are in the second position, the plurality of second rolling elements 2 are disengaged from the transmission plane. The first driving element 3 is configured to drive the plurality of first rolling elements 1 to rotate, so that the plate-shaped material 400 on the transmission plane can move along the first direction. The second driving element 4 is configured to drive the plurality of second rolling elements 2 to move to the first position and the second position.

[0048] Specifically, in practical applications, the feeding / discharging device 100 provided in this embodiment can be used for feeding and discharging plate-shaped materials 400. That is, it can be installed at the beginning and end of a conveying device 200, such as a conveyor belt, to receive materials from the robotic arm 300 or other gripping devices, or to supply or discharge materials to the robotic arm 300 or other gripping devices. In the production of photovoltaic cells, the feeding / discharging device 100 can be used for feeding or discharging glass substrates.

[0049] In this embodiment, the feeding / discharging device 100 includes a plurality of first rolling elements 1 connected to the first driving member 3 and arranged side-by-side along a first direction, and a plurality of second rolling elements 2 connected to the second driving member 4 and arranged side-by-side with the plurality of first rolling elements 1 to form a transmission plane. This allows the plate-shaped material 400 being fed or discharged to be supported on the transmission plane. When the first driving member 3 drives the plurality of first rolling elements 1 to rotate, the plate-shaped material 400 on the transmission plane can move along the first direction. (Refer to...) Figure 9 and Figure 10 During this process, multiple second rolling elements 2 are located in the first position, making the transmission plane more complete and avoiding material discharge or infeed jamming.

[0050] Furthermore, when it is necessary to discharge or feed the plate-shaped material 400 from the conveying plane, the second driving member 4 can drive the second rolling member 2 to move to the second position, so that the first position forms an empty space that can accommodate the fork arm 9 of the robot 300 or other device for gripping the plate-shaped material 400. This achieves the purpose of discharging or feeding material from the side of the feeding device 100, avoiding the operation in the prior art that requires moving the plate-shaped material 400 above the conveying plane and then rotating it 90° to pick up and put the plate-shaped material 400 from the gap of the large rollers. This shortens the production cycle of discharging and feeding material and improves production efficiency. Here, the side of the feeding device 100 refers to discharging or feeding material in the direction perpendicular to the material conveying direction (first direction) of the feeding device 100, which can save space and does not affect the production cycle.

[0051] In the above embodiments, the number and arrangement position of the second rolling elements 2 (i.e., the relative positions between the multiple second rolling elements 2 and the multiple first rolling elements 1) can be designed to match the shape or structural features of the material handling device. If the size of the portion of the device for handling plate-shaped material 400 that needs to extend into the transmission plane is large, multiple second rolling elements 2 can be arranged side by side at the corresponding positions. When it is necessary to drive the plate-shaped material 400, the second rolling elements 2 are kept at the first position. When it is necessary to handle the material, the second rolling elements 2 at the first position are moved to the second position, thus avoiding interference between the material handling device and the inlet / outlet device 100. In addition, the second position is preferably a nearby position that does not affect the handling of the material, but it can also be designed according to actual needs. This utility model does not impose any restrictions on this.

[0052] The feeding and discharging device 100 provided by this utility model has a simple structure. Under the premise of minimizing changes to the mechanical design, by setting a second rolling element 2, the plate-shaped material 400 can be fed and discharged from the side of the conveying device 200. Moreover, the device used for picking up and discharging materials does not need to rotate, saving process cycle time and meeting the production capacity requirements of the equipment.

[0053] Optionally, such as Figure 4 and Figure 5 As shown, the second position is located below the first position, and there is a set distance between the second position and the first position.

[0054] Specifically, in practical applications, the transmission plane of the feeding / discharging device 100 is usually at a certain height above the ground. By setting the second position of the second roller below the first position, the multiple second rolling elements 2 can be moved up and down by the second driving member 4 during the feeding / discharging process, further simplifying the movement process of the second rollers and improving production efficiency. The second driving member 4 can adopt a relatively simple linear actuator structure such as a cylinder, reducing equipment costs. The size of the set distance between the second position and the first position can be designed according to the actual size of the feeding / discharging device, allowing it to move below the transmission plane and then exit from the side; this invention does not impose any limitations on this. The second driving member 4 can be a cylinder or a motor, and can be set on a supporting structure such as a frame according to actual assembly requirements to meet height or transmission needs.

[0055] Optionally, such as Figure 1 , Figure 4 and Figure 5 As shown, the multiple second scroll members 2 are divided into arrays, and the array of second scroll members 2 are located at different positions of the multiple first scroll members 1.

[0056] Specifically, in this embodiment, multiple sets of second rolling elements 2 are respectively arranged at different positions of multiple first rolling elements 1, which can adapt to different material handling devices for material handling and discharging, thereby improving the production adaptability of the feeding device 100. For example Figure 1 As shown, a feeding device 100 with three sets of second rolling elements 2 is provided, wherein the first positions of the three sets of second rolling elements 2 are matched with... Figure 2 The fork arm 9 structure of the robot arm 300 allows the three sets of second rolling elements 2 to move from the first position to the second position through the drive of the second drive element 4 during the material handling process, so as to avoid the fork arm 9 structure of the robot arm 300.

[0057] Optionally, such as Figure 1 As shown, the feeding device 100 also includes a first support 5 and a second support 6; a plurality of first rolling elements 1 are movably mounted on the first support 5 and are respectively connected to the output end of the first driving element 3 through a transmission element; a plurality of second rolling elements 2 are fixedly mounted on the second support 6, and the output end of the second driving element 4 is connected to the second support 6.

[0058] Specifically, in this embodiment, the first bracket 5 enables multiple first rolling elements 1 to be connected to the first driving element 3 via a transmission component, and the second bracket 6 enables multiple second rolling elements 2 to be connected to the second driving element 4 via the second bracket 6, thereby improving the transmission efficiency of the first driving element 3 and the second driving element 4. Furthermore, the fact that multiple first rolling elements 1 are all mounted on the first bracket 5 and multiple second rolling elements 2 are all mounted on the second bracket 6 improves the overall integrity and modularity of the entire infeed / outfeed device 100, facilitating installation and disassembly. Both the first bracket 5 and the second bracket 6 can be designed as frame structures, which can meet the assembly requirements of each rolling element while also reducing the weight of the entire infeed / outfeed device 100, facilitating visual maintenance and disassembly, and reducing equipment costs.

[0059] Optionally, such as Figure 1 As shown, the first rolling element 1 includes a roller and a plurality of first rollers coaxially and spaced apart along the axial direction of the roller. The two ends of the roller are rotatably mounted on the first bracket 5, and the axial direction of the roller is perpendicular to the first direction. The second rolling element 2 includes a fixed shaft and a plurality of second rollers rotatably mounted on the fixed shaft. The two ends of the fixed shaft are fixed to the first bracket 5, and the axial direction of the fixed shaft is perpendicular to the first direction.

[0060] Specifically, in this embodiment, the first rolling element 1 includes a plurality of spaced-apart first rollers fixed on a roller shaft. The two ends of the roller shaft are rotatably mounted on the first bracket 5 via bearings or other structures, allowing the first driving element 3 to drive each roller shaft to rotate via a transmission element, thereby enabling the first rollers to rotate along a first direction. Simultaneously, the second rolling element 2 includes spaced-apart second rollers rotatably mounted on the second bracket 6, with each second roller and each first roller forming a transmission plane. When the first rollers rotate, they can drive the plate-shaped material 400 to move along the first direction. At the same time, the second rollers can rotate with the movement of the plate-shaped material 400, providing support for the material and preventing jamming during its movement.

[0061] The use of rollers for the rolling elements reduces their contact area with the plate material 400, improves transmission efficiency, and avoids wear on the plate material 400. In addition, the rollers also help reduce the weight of the rolling elements, and the space between two adjacent rollers can also avoid the structure on the plate material 400, so that the feeding device 100 can adapt to plate materials 400 of different shapes.

[0062] Optionally, such as Figure 1 As shown, the transmission component is a transmission rod, which is rotatably mounted on the first bracket 5 in the first direction. The transmission rod is connected to the ends of the first driving component 3 and multiple rollers through gear transmission.

[0063] Specifically, in this embodiment, the transmission rod is connected to multiple rollers and the output end of the first driving member 3 via gear structures, so that the power of the first driving member 3 can be transmitted to each roller, thereby driving the multiple first rollers to rotate and realizing the conveying of the plate-shaped material 400. The gear transmission improves the accuracy and efficiency of the transmission. The transmission rod can be mounted on the first bracket 5, near one end of each rotating shaft, with gear structures positioned corresponding to the ends of each rotating shaft. Each rotating shaft has a matching gear structure at its end, and the two mesh with each other to achieve transmission.

[0064] In one embodiment, the length of the fixed shaft is shorter than the length of the roller, so that in practical applications, the second rolling element 2 can avoid the transmission rod when moving between the first position and the second position.

[0065] According to the second aspect of this utility model, as Figures 3 to 5 As shown, a conveying production line is provided, including: a conveying device 200 and a first-aspect infeed device 100; the conveying device 200 is connected to the infeed device 100 and is capable of moving the plate-shaped material 400 on the conveying plane along a first direction to a set position.

[0066] Specifically, in this embodiment, a conveying production line is provided, which includes an infeed / outfeed device 100 for picking up and placing materials and a conveying device 200 for conveying plate-shaped materials 400. After the two devices are connected, the plate-shaped materials 400 on the infeed / outfeed device 100 can be conveyed to a set position through the conveying device 200. The set position can be a processing station in the next process, and is designed according to actual needs.

[0067] Optionally, such as Figure 4 and Figure 5 As shown, the transmission device 200 includes: a plurality of third rolling elements 7 and a third driving element 8; the plurality of third rolling elements 7 are arranged side by side with a plurality of first rolling elements 1 along a first direction to form a transmission plane; the third driving element 8 is configured to drive the plurality of third rolling elements 7 to rotate, so that the plate-shaped material 400 on the transmission plane moves to a set position.

[0068] Specifically, in this embodiment, the conveying device 200 includes multiple third rolling elements 7 and third driving elements 8, so that when the plate-shaped material 400 is placed into the infeed / outfeed device 100, it can be conveyed along the first direction by the second rolling elements 2 and the third rolling elements 7. The third rolling elements 7 and the second rolling elements 2 have the same structure. To facilitate assembly and adapt to different production sites and process requirements, the conveying device 200 can also be configured as a modular structure, adjusting the conveying length, direction, etc. of the entire conveying production line by setting one or more components to dock with the infeed / outfeed device 100.

[0069] Optionally, such as Figure 2 , Figures 6 to 10 As shown, the conveyor production line also includes a material pick-up and drop-off device. When the multiple second rolling elements 2 are in the second position, the material pick-up and drop-off device can pick up or drop materials at the first position.

[0070] Specifically, in practical applications, the pick-and-place device is used to place the plate-shaped material 400 on the feed-in device 100, or to remove the plate-shaped material 400 from the feed-in device 100. In this embodiment, the pick-and-place device can pick up or place material at a first position, allowing material to be discharged or fed from the side of the conveyor line without adjusting the direction of the pick-and-place device, thus saving production cycle time.

[0071] For example, in one embodiment, the material handling device is a robotic arm 300, which is equipped with a fork arm 9 with a three-pronged structure, such as... Figure 2 As shown. Correspondingly, the feeding / discharging device 100 has three sets of second rolling elements 2 at positions corresponding to the fork arm 9 structure, each corresponding to one of the three fork arms 9 of the robot arm 300. Taking the feeding process as an example, refer to... Figures 6 to 10 .

[0072] First, such as Figure 6 As shown, the robotic arm 300 picks up material from the side of the conveying device and moves it above the transmission plane. Simultaneously, the second driving component 4 drives the corresponding sets of second rolling components 2 to move from the first position to the second position. Figure 7 As shown, the robotic arm 300 continues to descend after the gap created by the three sets of second rolling elements 2 disengaging from the first position, allowing the plate-shaped material 400 to be placed on multiple first rolling elements 1 before exiting from below the first rolling element 1. (Refer to...) Figure 8 After the robotic arm 300 is extended, the second drive component 4 drives each group of first rolling components 1 to return from the second position to the first position, providing support for the plate-shaped material 400. (Refer to...) Figure 9 Then, the first driving member 3 drives each of the first rolling members 1 to rotate, so that the plate-shaped material 400 is conveyed to the conveying device 200 along the first direction. Next, the third driving member 8 drives the third rolling member 7 to rotate. (Refer to...) Figure 10 This allows the plate-shaped material 400 to be conveyed to the set position.

[0073] In the above process, each process step can be carried out simultaneously without affecting the overall process flow. In practical applications, the setting position and number of each second rolling element 2 of the feeding device 100 are designed to match the structure of the picking and placing device. The robotic arm 300 is a conventional picking and placing device for glass substrates in photovoltaic cell production, and the feeding device 100 can be matched with it. This utility model does not impose any restrictions on this.

[0074] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
