Description

Technical Field

[0001] The present application relates to, but is not limited to, the field of production equipment, and in particular to a feeding device, a mold changing structure, and a production line. Background Art

[0002] In the process of gluing the frames of photovoltaic products, the silo used to place the frames to be glued is placed at an angle. The related technology uses inefficient manual loading or the loading device structure is relatively complex. Utility Model Content

[0003] The loading device provided in the embodiment of the present application has a relatively simple structure and has a high loading efficiency.

[0004] In a first aspect, an embodiment of the present application provides a loading device, comprising a frame, a pick-and-place mechanism, and a moving mechanism. The frame is provided with a loading position, and the loading position is used to set a silo that carries a frame. The pick-and-place mechanism is used to pick up and place the frame. The moving mechanism includes a moving component and a connecting member, the moving component is connected to the frame, and the pick-and-place mechanism is connected to the moving component via the connecting member. The moving component can drive the pick-and-place mechanism to approach or move away from the loading position at least along a preset direction, and the connecting member is bent so that the bearing surface of the pick-and-place mechanism and the bearing surface of the silo meet the parallel condition. The preset direction is set at an angle to the bearing surface of the silo.

[0005] In the loading device provided in the embodiments of the present application, a movable assembly can drive the pick-and-place mechanism to move toward or away from the loading position along at least a predetermined direction, so as to place the frame taken by the pick-and-place mechanism into the loading position hopper, thereby realizing an automated loading process for the frame. Therefore, compared with the manual loading process in the related art, the loading efficiency of the loading device in the present application is higher. In addition, the movable assembly includes a bent connector so that the bearing surface of the pick-and-place mechanism and the bearing surface of the hopper meet the parallel condition. That is, the bent connector can make the bearing surface of the pick-and-place mechanism parallel to the bearing surface of the inclined hopper, so as to facilitate the pick-and-place mechanism to place the frame on the bearing surface of the hopper. Compared with the complex structure of the loading device in the related art, the loading device in the present application only needs to be provided with a bent connector to make the bearing surface of the pick-and-place mechanism parallel to the bearing surface of the inclined hopper, thereby reducing the complex structure of the frame to be placed in the inclined hopper, thereby reducing the structural complexity of the loading device. Therefore, the structure of the loading device in the present application is relatively simple and has a high loading efficiency.

[0006] In one possible implementation of the present application, the loading device further includes a reversing mechanism connected between the connecting member and the pick-and-place mechanism. The reversing mechanism includes a first rotating assembly, and the pick-and-place mechanism and the connecting member rotate relative to each other via the first rotating assembly so that the bearing surface of the pick-and-place mechanism faces toward or away from the silo.

[0007] Here, the setting of the first rotating assembly allows the pick-and-place mechanism and the connecting member to rotate relative to each other, so that the pick-and-place mechanism can pick up frames at different placement angles. After the pick-and-place mechanism picks up frames at different placement angles, the relative position of the pick-and-place mechanism and the connecting member can be adjusted by the first rotating assembly, so that the bearing surface of the pick-and-place mechanism can be parallel to the bearing surface of the silo, thereby enabling the pick-and-place mechanism to place the frame on the bearing surface of the silo. Moreover, after the pick-and-place mechanism picks up different surfaces of different frames, it can also enable all frames placed in the silo to contact the bearing surface of the silo with the same side. Therefore, the setting of the first rotating assembly enables the loading device in this application to be applied to a variety of different material-retrieving environments, thereby increasing the application scenarios of the loading device.

[0008] In a possible implementation of the present application, the connecting member includes a first connecting section connecting the pick-up and placement mechanism, and the rotation axis of the first rotating component and the central axis of the first connecting section meet the vertical condition, or the rotation axis of the first rotating component and the central axis of the first connecting section meet the parallel condition.

[0009] Here, when the rotation axis of the first rotating component and the central axis of the first connecting segment meet the vertical condition, the picking and placing mechanism can be flipped up and down relative to the first connecting segment. When the rotation axis of the first rotating component and the central axis of the first connecting segment meet the parallel condition, the picking and placing mechanism can rotate around the first connecting segment relative to the first connecting segment. These two different settings can be applied to different material picking environments so that the loading device can better complete the material picking process.

[0010] In a possible implementation of the present application, the reversing mechanism also includes a second rotating component, which is connected between the first rotating component and the pick-and-place mechanism. The pick-and-place mechanism and the first rotating component rotate relative to each other through the second rotating component, and the rotation axis of the second rotating component and the bearing surface of the pick-and-place mechanism meet the vertical condition.

[0011] Here, the provision of the second rotating assembly enables relative rotation between the pick-and-place mechanism and the first rotating assembly, further increasing the pick-and-place mechanism's degree of freedom. Consequently, after the pick-and-place mechanism picks up frames extending in different directions, the second rotating assembly can be used to adjust the relative rotational position of the pick-and-place mechanism's bearing surface and the first rotating assembly, so that each frame picked up by the pick-and-place mechanism is placed into the hopper in the desired orientation. Therefore, the provision of the second rotating assembly increases the flexibility of the loading device, enabling the loading device to meet a wider range of application scenarios.

[0012] In one possible implementation of the present application, the pick-and-place mechanism includes a base and a return assembly, the return assembly being connected to the base. The return assembly includes a return member, which is moved by a moving mechanism in a direction parallel to the support surface of the pick-and-place mechanism. Alternatively, the return assembly includes the return member and a first return drive member, the output end of the first return drive member being connected to the return member to drive the return member to move relative to the base along the support surface of the pick-and-place mechanism.

[0013] Here, the correction component can act before the pick-up and placement mechanism picks up the frame, so as to eliminate the gaps between the frames by correcting the frames through the correction component, thereby reducing the problem of some pick-up and placement parts of the pick-up and placement mechanism being misaligned with the frame during the process of the pick-up and placement mechanism picking up the frame, thereby improving the picking efficiency.

[0014] In a possible implementation of the present application, the correction component includes a second correction drive member, the correction member is connected to the output end of the second correction drive member, and the second correction drive member is used to drive the correction member to extend or retract relative to the bearing surface of the pick-and-place mechanism.

[0015] Here, when the return assembly returns the frame, the second return drive member causes the return member to extend relative to the support surface of the pick-and-place mechanism, so that the return member moves toward the frame and contacts the frame. After the return is completed, the second return drive member causes the return member to retract relative to the support surface of the pick-and-place mechanism. Therefore, the provision of the second return drive member can increase the flexibility of the return assembly.

[0016] In a possible implementation of the present application, the loading device further includes a detection mechanism, which is electrically connected to the correction component, and the detection mechanism is used to detect the relative position of the frame to be taken and the base.

[0017] Here, after the detection mechanism detects the relative position of the frame to be removed and the base, the loading device can determine whether the frame to be removed needs to be corrected based on its actual position relative to the base, and control the correction component to correct the frame if it needs to be corrected. Therefore, the provision of the detection mechanism can improve the automation level of the loading device.

[0018] In the second aspect, the embodiment of the present application also provides a change structure, which is applied to any one of the loading devices in the first aspect. The pick-up and placement mechanism of the loading device includes a base and at least two pick-up and placement components. The change structure includes at least two change parts. The change parts are provided with at least two limiting parts arranged equidistantly in sequence, and the spacing between two adjacent limiting parts in different change parts is different. The limiting parts are used to limit the position of the pick-up and placement components relative to the base in a one-to-one correspondence.

[0019] In the embodiment of the present application, the multiple limiting portions on each mold-changing member can limit the position of multiple pick-and-place components relative to the base body in a one-to-one correspondence. When the pick-and-place mechanism needs to pick up and place frames of different specifications and sizes, different mold-changing members in the mold-changing structure are placed in the pick-and-place mechanism, and each pick-and-place component of the pick-and-place mechanism is correspondingly limited at the limiting portions with different spacing sizes on different mold-changing members. This can quickly change the spacing size between adjacent pick-and-place components, so that the pick-and-place mechanism can pick up and place frames of different specifications and sizes. Therefore, the mold-changing structure in the present application can quickly adjust the spacing between each pick-and-place component on the pick-and-place mechanism, thereby improving the mold-changing efficiency of the pick-and-place mechanism.

[0020] In a possible implementation of the present application, the limiting portion includes a groove formed in the mold-changing member, and the groove is engaged and adapted with the pick-and-place assembly.

[0021] Here, the provision of the grooves makes the structure of the limiting portion simpler and also makes the changeover process of each pick-and-place component passing through each limiting portion more convenient.

[0022] In the third aspect, an embodiment of the present application also provides a production line, including any one of the loading devices in the first aspect, and also including a feeding device and a processing device, the feeding device is used to provide a frame to the loading device, and the processing device includes a silo for receiving and processing the frame delivered by the loading device.

[0023] The production line provided in the embodiment of the present application includes the loading device provided in the first aspect, and thus can achieve the same effect, that is, the structure of the loading device is relatively simple and has a higher loading efficiency.

DETAILED DESCRIPTION

[0039] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus comprising the element.

[0044] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0045] The present application provides a production line that can be used to assemble products with frames, such as windows, display frames, and photovoltaic products. Taking photovoltaic products as an example, photovoltaic products are used to convert solar energy into electrical energy and include photovoltaic modules and frames. The frames are assembled around the photovoltaic modules to provide protection and support for the modules.

[0046] In the process of gluing the frames of photovoltaic products, the silo used to place the frames to be glued is placed at an angle. The related technology uses inefficient manual loading or the loading device structure is relatively complex.

[0047] In view of this, see Figure 1 、 Figure 2 as well as Figure 3 , an embodiment of the present application provides a loading device, which includes a frame 1, a pick-and-place mechanism 2, and a moving mechanism 3. The frame 1 is provided with a loading position, which is used to set a silo 91 that carries the frame 6. The pick-and-place mechanism 2 is used to pick and place the frame 6. The moving mechanism 3 includes a moving component 31 and a connecting member 32. The moving component 31 is connected to the frame 1, and the pick-and-place mechanism 2 is connected to the moving component 31 through the connecting member 32. The moving component 31 can drive the pick-and-place mechanism 2 to approach or move away from the loading position at least along a preset direction, and the connecting member 32 is bent so that the bearing surface of the pick-and-place mechanism 2 and the bearing surface of the silo 91 meet the parallel condition. Among them, the preset direction is set at an angle to the bearing surface of the silo 91.

[0048] In the embodiment of the present application, the preset direction is the direction in which the bearing surface of the pick-and-place mechanism 2 moves relative to the frame 1 toward or away from the bearing surface of the silo 91. The silo 91 is tilted relative to the frame 1, so that the movement direction of the pick-and-place mechanism 2 relative to the frame 1 via the moving mechanism 3 forms an angle with the bearing surface of the silo 91, thereby forming an angle between the preset direction and the bearing surface of the silo 91. The connecting member 32 is bent so that the bearing surface of the pick-and-place mechanism 2 can be parallel to the bearing surface of the silo 91 when moving in the preset direction, thereby facilitating the pick-and-place mechanism 2 to place the frame 6 into the silo 91.

[0049] In one embodiment of the present application, see Figure 1 and Figure 2 The frame 1 includes two first support beams 11, a support frame 12, and a safety fence 13. The two first support beams 11 are fixed at intervals on the top side of the support frame 12 and extend along a first direction X. The safety fence 13 is arranged around the circumference of the support frame 12 to isolate and protect the frame 1. The moving assembly 31 of the moving mechanism 3 includes a second support beam 311, a slider, and a third support beam 312. The second support beam 311 is movably mounted on the first support beam 11 and is movable relative to the first support beam 11 in the first direction X. The third support beam 312 is movably mounted on the second support beam 311 via a slider. The slider is movable relative to the second support beam 311 in a second direction Y and relative to the slider in a third direction Z. Furthermore, a connector 32 connected to the pick-and-place mechanism 2 is fixedly connected to the third support beam 312, so that the moving assembly 31 can drive the pick-and-place mechanism 2 to move in the first direction X, the second direction Y, and the third direction Z.

[0050] It should be noted that the preset direction in the above embodiment can be one of the first direction X, the second direction Y and the third direction Z that can make the bearing surface of the picking and placing mechanism 2 close to or away from the bearing surface of the hopper 91, and a driving structure is provided between the first support beam 11 and the second support beam 311, between the second support beam 311 and the slider, and between the slider and the third support beam 312, for driving the second support beam 311 to move relative to the first support beam 11 along the first direction X, driving the slider provided with the third support beam 312 to move relative to the second support beam 311 along the second direction Y, and driving the third support beam 312 to move relative to the slider along the third direction Z.

[0051] In the embodiment of the present application, the bearing surface of the pick-and-place mechanism 2 is the pick-and-place surface for the pick-and-place mechanism 2 to pick up and place the frame 6, and the bearing surface of the silo 91 is the placement surface for the silo 91 to bear the weight of the frame 6 after the frame 6 is placed in the silo 91.

[0052] In the examples of this application, see Figure 3 and Figure 4 The parallel conditions that the carrying surface of the picking and placing mechanism 2 and the carrying surface of the silo 91 must meet include: one end of the connecting member 32 connected to the picking and placing mechanism 2 is parallel or approximately parallel to the carrying surface of the silo 91, and at least in the process of the picking and placing mechanism 2 placing the frame 6 into the silo 91, the carrying surface of the picking and placing mechanism 2 is parallel to the carrying surface of the silo 91.

[0053] Specifically, the pick-and-place mechanism 2 can be fixedly connected to one end of the connecting member 32 connected to the pick-and-place mechanism 2. Since the pick-and-place mechanism 2 is fixed to the connecting member 32, in order to make the bearing surface of the pick-and-place mechanism 2 and the bearing surface of the silo 91 meet the parallel condition, the bearing surface of the pick-and-place mechanism 2 and the bearing surface of the silo 91 need to be in a parallel state for a long time. Therefore, the end of the connecting member 32 connected to the pick-and-place mechanism 2, the bearing surface of the pick-and-place mechanism 2, and the bearing surface of the silo 91 are all parallel to each other. At this time, in order for the pick-and-place mechanism 2 to be able to pick up the frame 6, the frame 6 to be picked up must be placed parallel to the bearing surface of the silo 91. That is, under this setting, the end of the connecting member 32 connected to the pick-and-place mechanism 2, the bearing surface of the pick-and-place mechanism 2, the frame 6 to be picked up, and the bearing surface of the silo 91 are all parallel to each other.

[0054] The pick-and-place mechanism 2 can also be rotatably connected to the end of the connecting member 32 that is connected to the pick-and-place mechanism 2. Because the pick-and-place mechanism 2 and the connecting member 32 can rotate relative to each other, when the pick-and-place mechanism 2 picks up the frame 6, an angle can be formed between the load surface of the pick-and-place mechanism 2 and the load surface of the silo 91. When the pick-and-place mechanism 2 places the frame 6 into the silo 91, the pick-and-place mechanism 2 can be rotated relative to the connecting member 32 to make the load surface of the pick-and-place mechanism 2 parallel to the load surface of the silo 91. This ensures that the load surface of the pick-and-place mechanism 2 and the load surface of the silo 91 meet the parallel condition, thereby facilitating the pick-and-place mechanism 2 to place the picked-up frame 6 into the silo 91. In this case, since the pick-and-place mechanism 2 is rotated relative to the connecting member 32, it can pick up the frame 6 at any placement angle. Therefore, the frame 6 to be picked up can be arranged parallel to the load surface of the silo 91 or at an angle. In other words, in this arrangement, it is only necessary to make the end of the connecting member 32 connected to the pick-and-place mechanism 2 parallel to the load surface of the silo 91.

[0055] In the examples of this application, see Figure 5 The pick-and-place mechanism 2 includes a base 21 and a pick-and-place assembly 23. The base 21 is used to carry and connect the pick-and-place assembly 23. The number of the pick-and-place assembly 23 can be set to one or more. When the number of the pick-and-place assembly 23 is set to more than one, the multiple pick-and-place assemblies 23 are arranged in sequence on the base 21. Moreover, each pick-and-place assembly 23 can pick up and place one frame 6. Therefore, when the number of the pick-and-place assembly 23 is set to more than one, the pick-and-place mechanism 2 can pick up and place multiple frames 6 at a time, thereby improving the loading efficiency of the loading device.

[0056] The base 21 includes a first base portion 211 and a second base portion 212. The first base portion 211 and the second base portion 212 are fixedly connected, and the connector 32 is connected to the first base portion 211, and the pick-and-place assembly 23 is connected to the second base portion 212. The first base portion 211 is configured to adapt to the connector 32. For example, the first base portion 211 can be configured as a connecting block corresponding to the position of the connector 32. The second base portion 212 is configured to adapt to the pick-and-place assembly 23. For example, the second base portion 212 can be configured as a frame structure to improve the flexibility between the connector 32 and the pick-and-place assembly 23 and reduce the weight of the base 21. In addition, the base 21 can also be configured as a plate-like structure, a frame structure, etc.

[0057] Furthermore, the pick-and-place assembly 23 includes a main body 231 and a pick-and-place member 232. The main body 231 is connected to the second base 212, and the pick-and-place member 232 is connected to the main body 231. The number of the pick-and-place member 232 can be one or more. When there are multiple pick-and-place members 232, the multiple pick-and-place members 232 are spaced apart on the main body 231. Furthermore, the pick-and-place member 232 can be configured as a claw, a suction cup, or other structure, which is not specifically limited in this application.

[0058] In the loading device provided in the embodiment of the present application, the moving assembly 31 can drive the pick-and-place mechanism 2 to approach or move away from the loading position at least along a preset direction, so as to place the frame 6 taken by the pick-and-place mechanism 2 into the hopper 91 at the loading position, thereby realizing an automated loading process of the frame 6. Therefore, compared with the manual loading process in the related art, the loading efficiency of the loading device in the present application is higher. In addition, the moving mechanism 3 includes a bent connection member 32 so that the bearing surface of the pick-and-place mechanism 2 and the bearing surface of the hopper 91 meet the parallel condition, that is, the bent connection member 32 can make the bearing surface of the pick-and-place mechanism 2 parallel to the bearing surface of the inclined hopper 91, so as to facilitate the pick-and-place mechanism 2 to place the frame 6 on the bearing surface of the hopper 91. Compared to the complex loading devices in the related art, the loading device of the present application only requires a bent connector 32 to allow the loading surface of the pick-and-place mechanism 2 to be parallel to the loading surface of the tilted hopper 91. This reduces the need for complex structures such as joints and ball joints that allow the frame 6 to be placed in the tilted hopper 91, thereby reducing the structural complexity of the loading device. Therefore, the loading device of the present application has a relatively simple structure and high loading efficiency.

[0059] See also Figure 6 In some possible embodiments of the present application, the loading device further includes a reversing mechanism 4, which is connected between the connecting member 32 and the pick-and-place mechanism 2. The reversing mechanism 4 includes a first rotating assembly 41, and the pick-and-place mechanism 2 and the connecting member 32 rotate relative to each other via the first rotating assembly 41, so that the bearing surface of the pick-and-place mechanism 2 faces toward or away from the hopper 91.

[0060] In an embodiment of the present application, the first rotating assembly 41 includes a first driving member and a first rotating shaft. The first driving member is connected to the connecting member 32 and is in transmission connection with the first rotating shaft, and is used to drive the first rotating shaft to rotate relative to the connecting member 32, thereby driving the picking and placing mechanism 2 arranged on the first rotating shaft to rotate relative to the connecting member 32.

[0061] In one embodiment of the present application, see Figure 7 and Figure 8 The feeding device 8 includes a plurality of stacked frame group layers, each frame group layer includes a plurality of frame groups, and each frame group includes two frames 6 placed front and back. The first surfaces 61 of the two frames 6 placed front and back are arranged opposite to each other, and the second surfaces 62 are arranged facing each other, so that the first surface 61 of one frame 6 of each frame group faces upward, and the first surface 61 of the other frame 6 faces downward. Moreover, when the pick-up and placement mechanism 2 places the frame 6 on the bearing surface of the silo 91, it is necessary to make the first surfaces 61 of all the frames 6 face the bearing surface of the silo 91. At this time, if the pick-up and placement mechanism 2 takes the frame 6 with the first surface 61 facing upward, the pick-up and placement mechanism 2 moves to the entrance end of the silo 91 (that is, Figure 4In the process of the upper right end of the middle silo 91), see Figure 9 The picking and placing mechanism 2 is flipped upward by the first rotating component 41 relative to the end of the picking and placing mechanism 2 connected to the connecting member 32, so that the bearing surface of the picking and placing mechanism 2 is parallel to the bearing surface of the silo 91. Then the picking and placing mechanism 2 releases the frame 6, so that the first surface 61 of the frame 6 can slide into the bearing surface of the silo 91, thereby completing the placement process of the frame 6.

[0062] If the pick-up and place mechanism 2 takes the frame 6 with the first surface 61 facing downward, the pick-up and place mechanism 2 moves toward the entry end of the hopper 91 through the moving mechanism 3, see Figure 10 The picking and placing mechanism 2 is flipped downward by the first rotating component 41 relative to one end of the picking and placing mechanism 2 connected to the connecting member 32, so that the bearing surface of the picking and placing mechanism 2 is parallel to the bearing surface of the silo 91. Then the picking and placing mechanism 2 releases the frame 6, so that the first surface 61 of the frame 6 can slide into the bearing surface of the silo 91, thereby completing the placement process of the frame 6.

[0063] In some embodiments, see Figure 2 、 Figure 7 and Figure 8 , an interlayer of paper is provided between two adjacent frame groups of the feeding device 8. The number of the pick-and-place components 23 included in the pick-and-place mechanism 2 is the same as the number of frames 6 placed upright or inverted in each frame group layer, so that the pick-and-place mechanism 2 can pick up all the frames 6 placed upright or inverted in a frame group layer at a time. Moreover, when the pick-and-place mechanism 2 takes all the frames 6 placed upright in each frame group layer, it can take up the interlayer of paper, and after moving the interlayer of paper to the position where the paper recycling box 14 is located, the pick-and-place mechanism 2 is flipped by the first rotating component 41 relative to the end of the connecting member 32 connected to the pick-and-place mechanism 2, so that the interlayer of paper falls into the paper recycling box 14. This arrangement makes it unnecessary to set up an additional paper picking mechanism for the feeding device, thereby making the structure of the feeding device simpler.

[0064] In the technical solution of the embodiment of the present application, the first rotating assembly 41 is provided so that the pick-and-place mechanism 2 and the connecting member 32 can rotate relative to each other, so that the pick-and-place mechanism 2 can pick up the frame 6 at different placement angles, such as a frame 6 placed horizontally or at an angle to the horizontal plane. After the pick-and-place mechanism 2 picks up the frame 6 at different placement angles, the first rotating assembly 41 can be used to adjust the relative position of the pick-and-place mechanism 2 and the connecting member 32 so that the carrying surface of the pick-and-place mechanism 2 can be parallel to the carrying surface of the silo 91, thereby facilitating the pick-and-place mechanism 2 to place the frame 6 on the carrying surface of the silo 91. Moreover, after the pick-and-place mechanism 2 picks up different faces of different frames 6, it can also ensure that all frames 6 placed in the silo 91 contact the carrying surface of the silo 91 with the same side surface. For example, after the pick-and-place mechanism 2 picks up the first face 61 or the second face 62 of the frame 6, the first rotating assembly 41 can be used to drive the pick-and-place mechanism 2 to rotate so that the first face 61 of all frames 6 placed in the silo 91 by the pick-and-place mechanism 2 is facing the carrying surface of the silo 91. Therefore, the provision of the first rotating assembly 41 enables the loading device in the present application to be applied to a variety of different material-taking environments, thereby increasing the application scenarios of the loading device.

[0065] See also Figure 3 and Figure 6 In some possible embodiments of the present application, the connecting member 32 includes a first connecting section 321 connecting the pick-and-place mechanism 2, and the rotation axis L1 of the first rotating component 41 and the central axis of the first connecting section 321 meet the vertical condition, or the rotation axis L1 of the first rotating component 41 and the central axis of the first connecting section 321 meet the parallel condition.

[0066] In the embodiment of the present application, the end of the connector 32 connected to the pick-and-place mechanism 2 is the first connector section 321. The connector 32 includes a first connector section 321 connected to the pick-and-place mechanism 2 and a second connector section 322 connected to the third support beam 312 of the movable assembly 31. The first connector section 321 is fixedly connected to the second connector section 322, and the first connector section 321 is bent relative to the second connector section 322 so that the central axis of the first connector section 321 is parallel to the supporting surface of the silo 91.

[0067] In the examples of this application, see Figure 6 The rotation axis L1 of the first rotating component 41 and the central axis of the first connecting section 321 meet the vertical condition, that is, the rotation axis L1 of the first rotating component 41 is perpendicular or approximately perpendicular to the central axis of the first connecting section 321, so that the pick-up and placement mechanism 2 can be flipped up and down relative to the first connecting section 321 through the first rotating component 41, so that at least in the process of the pick-up and placement mechanism 2 placing the frame 6 into the hopper 91, the bearing surface of the pick-up and placement mechanism 2 is parallel to the bearing surface of the hopper 91, thereby completing the loading process.

[0068] In the embodiment of the present application, the rotation axis L1 of the first rotating component 41 and the central axis of the first connecting section 321 meet the parallel condition, that is, the rotation axis L1 of the first rotating component 41 is parallel or approximately parallel to the central axis of the first connecting section 321, and the bearing surface of the picking and placing mechanism 2 is parallel to the first connecting section 321, so that the bearing surface of the picking and placing mechanism 2 can rotate around the first connecting section 321 through the first rotating component 41, that is, the bearing surface of the picking and placing mechanism 2 can rotate around the first connecting section 321 in its circumferential direction, so that at least in the process of the picking and placing mechanism 2 placing the frame 6 into the hopper 91, the bearing surface of the picking and placing mechanism 2 is parallel to the bearing surface of the hopper 91, thereby completing the loading process. It should be noted that since the carrying surface of the picking and placing mechanism 2 can only rotate in its circumferential direction around the first connecting section 321, that is, the picking and placing mechanism 2 cannot be flipped up and down relative to the first connecting section 321, it is difficult or impossible for the picking and placing mechanism 2 to pick up the frame 6 placed at an angle to the carrying surface of the picking and placing mechanism 2. Therefore, under this setting, the frame 6 to be picked up is placed parallel to the carrying surface of the picking and placing mechanism 2.

[0069] In the technical solution of the embodiment of the present application, when the rotation axis L1 of the first rotating component 41 and the central axis of the first connecting segment 321 meet the vertical condition, the picking and placing mechanism 2 can be flipped up and down relative to the first connecting segment 321. When the rotation axis L1 of the first rotating component 41 and the central axis of the first connecting segment 321 meet the parallel condition, the picking and placing mechanism 2 can rotate around the first connecting segment 321 relative to the first connecting segment 321. These two different settings can be applied to different material-picking environments so that the loading device can better complete the material-picking process.

[0070] See also Figure 6 In some possible embodiments of the present application, the reversing mechanism 4 also includes a second rotating component 42, which is connected between the first rotating component 41 and the pick-and-place mechanism 2. The pick-and-place mechanism 2 and the first rotating component 41 rotate relative to each other through the second rotating component 42, and the rotation axis L2 of the second rotating component 42 and the bearing surface of the pick-and-place mechanism 2 meet the vertical condition.

[0071] In the embodiment of the present application, the second rotating component 42 includes a second driving member and a second rotating shaft. The second driving member is connected to the first rotating component 41 and is transmission-connected to the second rotating shaft, and is used to drive the second rotating shaft to rotate relative to the first rotating component 41, thereby driving the pick-and-place mechanism 2 set on the second rotating shaft to rotate relative to the first rotating component 41.

[0072] In the embodiment of the present application, the rotation axis L2 of the second rotating component 42 and the bearing surface of the pick-and-place mechanism 2 meet the vertical condition, that is, the rotation axis L2 of the second rotating component 42 is vertical or approximately vertical to the bearing surface of the pick-and-place mechanism 2, so that the pick-and-place mechanism 2 can rotate through the second rotating component 42.

[0073] In the technical solution of the embodiment of the present application, the provision of the second rotating assembly 42 enables relative rotation between the pick-and-place mechanism 2 and the first rotating assembly 41, thereby further increasing the degree of freedom of the pick-and-place mechanism 2. Furthermore, after the pick-and-place mechanism 2 picks up the frame 6 in different extension directions, the relative rotational position of the carrying surface of the pick-and-place mechanism 2 and the first rotating assembly 41 can be adjusted by the second rotating assembly 42, so that the frame 6 picked up by the pick-and-place mechanism 2 is placed into the hopper 91 in the actual required direction. Therefore, the provision of the second rotating assembly 42 can increase the flexibility of the loading device, so that the loading device can meet more application scenarios.

[0074] See also Figure 6 、 Figure 11 and Figure 12 In some possible embodiments of the present application, the pick-and-place mechanism 2 includes a base 21 and a return assembly 22, which is connected to the base 21. The return assembly 22 includes a return member 221, which is moved in a direction parallel to the bearing surface of the pick-and-place mechanism 2 by the moving mechanism 3; or, the return assembly 22 includes the return member 221 and a first return driving member, the output end of the first return driving member being connected to the return member 221 to drive the return member 221 to move relative to the base 21 along the bearing surface of the pick-and-place mechanism 2.

[0075] It should be noted that the correction component 22 can act before the picking and placing mechanism 2 picks up the frame 6, so as to eliminate the gap between the frames 6 by correcting the frames 6 through the correction component 22, and then reduce the problem of some picking and placing parts 232 of the picking and placing mechanism 2 not being aligned with the frame 6 during the process of the picking and placing mechanism 2 picking up the frame 6, so as to improve the picking efficiency.

[0076] In the embodiment of the present application, the structure of the base 21 has been described above and will not be repeated here.

[0077] In the embodiment of the present application, when the correcting member 221 moves in a direction parallel to the bearing surface of the pick-up and placement mechanism 2 through the moving mechanism 3, since the pick-up and placement mechanism 2 as a whole moves with the moving mechanism 3, if the moving mechanism 3 moves in a direction parallel to the bearing surface of the pick-up and placement mechanism 2, it can drive the correcting member 221 of the pick-up and placement mechanism 2 to move in a direction parallel to the bearing surface of the pick-up and placement mechanism 2, thereby correcting the frame 6.

[0078] When the correcting member 221 moves relative to the base 21 along the bearing surface of the pick-and-place mechanism 2 through the first correcting driving member, the first correcting driving member is connected to the second base portion 212 of the base 21, and can be in an extended state or shortened state relative to the second base portion 212 along the direction parallel to the bearing surface of the pick-and-place mechanism 2, so as to drive the correcting member 221 to move relative to the base 21 along the bearing surface of the pick-and-place mechanism 2, thereby correcting the frame 6.

[0079] In the embodiments of the present application, the first alignment driver can be a motor, a rotary cylinder, or other drive component with a rotational output shaft, or a hydraulic cylinder, a pneumatic cylinder, an electric telescopic rod, or other drive component with a linear output shaft. The motor can be a servo motor, a stepper motor, or the like. In one example, the first alignment driver is a pneumatic cylinder, which is fixedly connected to the second base 212, and the output end of the cylinder is fixedly connected to the alignment member 221.

[0080] See also Figure 6 、 Figure 11 and Figure 12 In some possible embodiments of the present application, the correction component 22 includes a second correction driving member 222, the correction member 221 is connected to the output end of the second correction driving member 222, and the second correction driving member 222 is used to drive the correction member 221 to extend or retract relative to the bearing surface of the pick-and-place mechanism 2.

[0081] In the embodiment of the present application, the second alignment driving member 222 is connected to the second base 212 through a connecting plate 223, and the number of connecting plates 223 can be one or more. When the number of connecting plates 223 is multiple, the multiple connecting plates 223 are arranged at intervals.

[0082] In the embodiment of the present application, the output end of the second alignment driver 222 extends or retracts relative to the support surface of the pick-and-place mechanism 2, thereby driving the alignment member 221 to extend or retract relative to the support surface of the pick-and-place mechanism 2. The second alignment driver 222 can be a driver with a rotational output shaft, such as a motor or a rotary cylinder, or a driver with a linear output shaft, such as a hydraulic cylinder, a pneumatic cylinder, or an electric telescopic rod. The motor can be a servo motor, a stepper motor, or the like. In one example, the second alignment driver 222 is a pneumatic cylinder, which is connected to the second base 212 via a connecting plate 223, and the output end of the cylinder is fixedly connected to the alignment member 221.

[0083] In the embodiment of the present application, when the correction component 22 corrects the frame 6, the second correction driving member 222 drives the correction member 221 to extend relative to the bearing surface of the pick-and-place mechanism 2, so that the correction member 221 moves toward the frame 6 and contacts the frame 6, and then the pick-and-place mechanism 2 as a whole moves along with the moving mechanism 3 in a direction parallel to the bearing surface of the pick-and-place mechanism 2, so as to drive the correction member 221 that contacts the frame 6 to move along a direction parallel to the bearing surface of the pick-and-place mechanism 2 and push the frame 6, or the correction member 221 that contacts the frame 6 moves along with the first correction driving member relative to the base 21 along the bearing surface of the pick-and-place mechanism 2 and pushes the frame 6, so as to correct the frame 6. After the correction is completed, the second correction driving member 222 drives the correction member 221 to retract relative to the bearing surface of the pick-and-place mechanism 2. Therefore, the provision of the second correction driving member 222 can increase the flexibility of the correction component 22.

[0084] In some other embodiments, the correcting assembly 22 may not be provided with the second correcting drive member 222. In this case, the correcting member 221 is located at the periphery of each pick-up and placement member 232 and is spaced a certain distance from each pick-up and placement member 232. Furthermore, the correcting member 221 is protruding relative to the surface of each pick-up and placement member 232 that picks up the frame 6, so that the correcting member 221 contacts the frame 6 before the pick-up and placement member 232. The correcting member 221 is driven by the pick-up and placement mechanism 2 as a whole along with the movement of the moving mechanism 3 to move in a direction parallel to the bearing surface of the pick-up and placement mechanism 2 and push the frame 6, or the correcting member 221 is driven by the first correcting drive member to move along the bearing surface of the pick-up and placement mechanism 2 and push the frame 6, thereby correcting each frame 6 before the pick-up and placement member 232 picks up the frame 6. After the correction is completed, the pick-up and placement mechanism 2 as a whole moves along with the moving mechanism 3, so that the correcting member 221 moves to the periphery of the frame 6, thereby enabling the pick-up and placement member 232 to contact and pick up the frame 6.

[0085] See also Figure 11 In some possible embodiments of the present application, the loading device further includes a detection mechanism 5, which is electrically connected to the correction component 22, and the detection mechanism 5 is used to detect the relative position of the frame 6 to be taken and the base 21.

[0086] In the embodiment of the present application, after the detection mechanism 5 detects the relative position of the frame 6 to be taken and the base 21, the loading device can determine whether the frame 6 to be taken needs to be corrected based on the actual position of the frame 6 to be taken relative to the base 21, and control the correcting component 22 to correct the frame 6 when the frame 6 to be taken needs to be corrected. Therefore, the provision of the detection mechanism 5 can improve the degree of automation of the loading device.

[0087] In the embodiment of the present application, the detection mechanism 5 can be set on the base 21 or on the moving mechanism 3, and the specific setting can be based on actual needs.

[0088] In the embodiment of the present application, the detection mechanism 5 may include one or more different types of sensors. The sensor may be an image sensor, such as a camera; the sensor may also be a distance sensor, such as a dimension measuring instrument.

[0089] See also Figure 11 and Figure 13 The embodiment of the present application also provides a change structure, which is applied to the loading device in the embodiment of the present application. The pick-up and placement mechanism 2 of the loading device includes a base 21 and at least two pick-up and placement components 23. The change structure includes at least two change parts 7. The change part 7 is provided with at least two limiting parts 71 arranged in sequence and equidistantly, and the spacing between two adjacent limiting parts 71 in different change parts 7 is different. The limiting parts 71 are used to limit the position of the pick-up and placement components 23 relative to the base 21 in a one-to-one correspondence.

[0090] In the embodiment of the present application, the number of the changeable members 7 included in the changeable structure can be two, three, etc., and the spacing between two adjacent limiting portions 71 in the multiple changeable members 7 can gradually increase or decrease with the same difference.

[0091] In an embodiment of the present application, a plurality of limiting portions 71 can be respectively provided on the opposite sides of each mold-changing member 7, and the spacing dimensions between two adjacent limiting portions 71 on the opposite sides of each mold-changing member 7 are different, so that the opposite sides of each mold-changing member 7 can respectively enable the adjacent pick-up and placement components 23 to be at two different spacing dimensions, thereby improving the utilization rate of each mold-changing member 7.

[0092] In the embodiment of the present application, the limiting portion 71 can be a clamping structure, a groove structure, etc. adapted to the pick-and-place assembly 23 .

[0093] In the embodiment of the present application, the multiple position limiting portions 71 on each of the changeable members 7 can limit the positions of the multiple pick-and-place components 23 relative to the base 21. When the pick-and-place mechanism 2 needs to pick up and place frames 6 of different sizes, different changeable members 7 in the changeable structure are placed on the pick-and-place mechanism 2, and the pick-and-place components 23 of the pick-and-place mechanism 2 are correspondingly limited at the position limiting portions 71 with different spacing sizes on different changeable members 7. This allows the spacing between adjacent pick-and-place components 23 to be quickly changed, so that the pick-and-place mechanism 2 can pick up and place frames 6 of different sizes. Therefore, the changeable structure of the present application can quickly adjust the spacing between the pick-and-place components 23 on the pick-and-place mechanism 2, thereby improving the change-over efficiency of the pick-and-place mechanism 2.

[0094] See also Figure 13 In some possible embodiments of the present application, the limiting portion 71 includes a groove 711 opened on the mold-changing member 7, and the groove 711 is engaged and adapted with the pick-and-place assembly 23.

[0095] In the embodiment of the present application, when it is necessary to adjust the spacing size between adjacent pick-and-place components 23 of the pick-and-place mechanism 2, each pick-and-place component 23 and the second base 212 of the pick-and-place mechanism 2 are disassembled so that each pick-and-place component 23 can move relative to the second base 212, and then the position of each pick-and-place component 23 is adjusted so that each groove 711 of the change piece 7 with the required spacing size is stuck on the corresponding pick-and-place component 23, and then each pick-and-place component 23 is fixed to the second base 212, and the change piece 7 placed on each pick-and-place component 23 is removed, and the adjustment of the spacing size between adjacent pick-and-place components 23 can be completed.

[0096] In the embodiment of the present application, the provision of the groove 711 makes the structure of the limiting portion 71 simpler and also makes the replacement process of each pick-and-place component 23 passing through each limiting portion 71 more convenient.

[0097] See also Figure 1 、 Figure 2 、 Figure 4 as well as Figure 7 The embodiment of the present application also provides a production line, including the loading device in the embodiment of the present application, and also including a feeding device 8 and a processing device 9. The feeding device 8 is used to provide a frame 6 to the loading device, and the processing device 9 includes a silo 91 for receiving and processing the frame 6 delivered by the loading device.

[0098] In the embodiment of the present application, the feeding device 8 includes a pallet, a pallet truck, etc. The processing device 9 includes a gluing platform, and the frame 6 in the silo 91 can be transported to the gluing platform for gluing and then transported to the assembly equipment for framing of the photovoltaic module.

[0099] In the production line provided by the embodiment of the present application, since the end of the connecting member 32 of the loading device connected to the pick-and-place mechanism 2 is parallel or approximately parallel to the bearing surface of the hopper 91, when the pick-and-place mechanism 2 places the frame 6 into the hopper 91, the bearing surface of the pick-and-place mechanism 2 can be parallel to the bearing surface of the hopper 91, so that the pick-and-place mechanism 2 can place the frame 6 on the bearing surface of the hopper 91. Therefore, the loading device in the production line of the present application can reduce the complex structures such as joint structures and ball joint structures that enable the frame 6 to be placed in the inclined hopper 91, thereby reducing the structural complexity of the loading device. In addition, the pick-and-place mechanism 2 can pick up and place multiple frames 6 at the same time, thereby improving the loading efficiency of the loading device.

[0100] The loading process of the production line is as follows: the moving mechanism 3 moves on the frame 1, driving the pick-and-place mechanism 2 disposed on the moving mechanism 3 to move until it reaches above the feeding device 8. The first rotating assembly 41 controls the pick-and-place mechanism 2 to rotate relative to the connecting member 32 so that the bearing surface of the pick-and-place mechanism 2 is parallel to each frame 6 placed on the feeding device 8. Then, the detection mechanism 5 detects the relative position of each frame 6 placed on the feeding device 8 and the base 21. When it is determined that there is a gap between adjacent frames 6 placed on the feeding device 8, the control unit 22 starts to work, causing the return member 221 to move in a direction parallel to the bearing surface of the pick-and-place mechanism 2 to eliminate the gap between adjacent frames 6 placed on the feeding device 8 and then retract the return unit 22. Then, the moving mechanism 3 is controlled to move relative to the frame 1 toward the feeding device 8, and drives each pick-and-place assembly 23 of the pick-and-place mechanism 2 to pick up the corresponding frame 6, so that the pick-and-place mechanism 2 can pick up multiple frames 6 at a time, for example, the pick-and-place mechanism 2 can pick up a layer of frames 6 placed on the feeding device 8 at a time. Then, the moving mechanism 3 is controlled to drive the pick-and-place mechanism 2 to move relative to the frame 1 toward the hopper 91 of the processing device 9, and to make the pick-and-place mechanism 2 approach the entry end of the hopper 91 along a preset direction. In this process, it is determined whether the bearing surface of the pick-and-place mechanism 2 is parallel to the bearing surface of the hopper 91, and when the bearing surface of the pick-and-place mechanism 2 forms an angle with the bearing surface of the hopper 91, the pick-and-place mechanism 2 is controlled to rotate relative to the connecting member 32 through the first rotating component 41, so that the bearing surface of the pick-and-place mechanism 2 is parallel to the bearing surface of the hopper 91, and then the pick-and-place mechanism 2 can be controlled to rotate along its own circumference through the second rotating component 42, so that the frame 6 picked up by the pick-and-place mechanism 2 can be placed into the bearing surface of the hopper 91 at the actual required angle. When the pick-and-place mechanism 2 releases the frame 6, the frame 6 can slide into the bearing surface of the hopper 91, thereby completing the placement process of the frame 6.

[0101] The above are only preferred embodiments of the present application and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
