[0038] The embodiments of the present disclosure provide a production line, which can be used for assembly of a frame-containing product, and the frame-containing product can include a window, a display frame, a photovoltaic product, etc. Taking the photovoltaic product as an example, the photovoltaic product is configured to convert solar energy into electrical energy, and the photovoltaic product includes a photovoltaic assembly and a frame, and the frame is assembled on the side of the photovoltaic assembly to provide protection and support for the photovoltaic assembly.

[0039] In the frame gluing process of the photovoltaic product, the stock bin configured to place the frame to be glued is placed obliquely, and the related art adopts low-efficiency manual feeding or a feeding device structure which is relatively complex.

[0040] In view of this, referring to FIG. 1, FIG. 2 and FIG. 3, the embodiment of the present disclosure provides a feeding device, which comprises a rack 1, a taking and placing mechanism 2 and a moving mechanism 3. The rack 1 is provided with a feeding position, and the feeding position is configured to be provided with a stock bin 91 carrying a frame 6. The taking and placing mechanism 2 is configured to take and place the frame 6. The moving mechanism 3 comprises a moving assembly 31 and a connecting piece 32, the moving assembly 31 is connected to the rack 1, the taking and placing mechanism 2 is connected to the moving assembly 31 through the connecting piece 32, the moving assembly 31 can drive the taking and placing mechanism 2 to at least approach or move away from the feeding position along a preset direction, and the connecting piece 32 is bent to be arranged so that the carrying surface of the taking and placing mechanism 2 and the carrying surface of the stock bin 91 satisfy the parallel condition. The preset direction is arranged at an angle with the carrying surface of the stock bin 91.

[0041] In the embodiment of the present disclosure, the preset direction is the movement direction of the carrying surface of the taking and placing mechanism 2 relative to the carrying surface of the stock bin 91 moving towards or away from the rack 1. The stock bin 91 is arranged obliquely relative to the rack 1, so that the movement direction of the taking and placing mechanism 2 moving relative to the rack 1 through the moving mechanism 3 forms an angle with the carrying surface of the stock bin 91, so that the preset direction forms an angle with the carrying surface of the stock bin 91. The connecting piece 32 is bent to be arranged so that when the carrying surface of the taking and placing mechanism 2 moves along the preset direction, it can be parallel to the carrying surface of the stock bin 91, thereby facilitating the taking and placing mechanism 2 to place the frame 6 to the stock bin 91.

[0042] In an embodiment of the present disclosure, referring to FIG. 1 and FIG. 2, the rack 1 comprises two first support beams 11, a support frame 12 and a safety fence 13, the two first support beams 11 are fixedly arranged at the top side of the support frame 12 and extend along a first direction X, and the safety fence 13 is arranged around the circumferential side of the support frame 12 and is configured to isolate the rack 1 and protect the rack 1. The moving assembly 31 of the moving mechanism 3 comprises a second support beam 311, a sliding block and a third support beam 312, wherein the second support beam 311 is movably arranged on the first support beam 11 and can move along the first direction X relative to the first support beam 11. The third support beam 312 is movably arranged on the second support beam 311 through the sliding block, the sliding block can move along a second direction Y relative to the second support beam 311, the third support beam 312 can move along a third direction Z relative to the sliding block, and the connecting piece 32 connected with the taking and placing mechanism 2 is fixedly connected to the third support beam 312, so that the moving assembly 31 can drive the taking and placing mechanism 2 to move along the first direction X, the second direction Y and the third direction Z.

[0043] 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, which can make the bearing surface of the taking and placing mechanism 2 close to or away from the bearing surface of the material bin 91, and the driving structure is arranged between the first support beam 11 and the second support beam 311, between the second support beam 311 and the sliding block, and between the sliding block and the third support beam 312, which is configured to drive the second support beam 311 to move relative to the first support beam 11 along the first direction X, drive the sliding block provided with the third support beam 312 to move relative to the second support beam 311 along the second direction Y, and drive the third support beam 312 to move relative to the sliding block along the third direction Z.

[0044] In the embodiment of the present disclosure, the bearing surface of the taking and placing mechanism 2 is the taking and placing surface of the taking and placing mechanism 2 for taking and placing the frame 6, and the bearing surface of the material bin 91 is the placing surface of the material bin 91 for bearing the weight of the frame 6 after the frame 6 is placed in the material bin 91.

[0045] In the embodiment of the present disclosure, referring to FIGS. 3 and 4, the parallel conditions that the bearing surface of the taking and placing mechanism 2 and the bearing surface of the material bin 91 need to meet include that the end of the taking and placing mechanism 2 connected by the connecting member 32 and the bearing surface of the material bin 91 are in a parallel or approximately parallel state, and at least during the process of placing the frame 6 in the material bin 91 by the taking and placing mechanism 2, the bearing surface of the taking and placing mechanism 2 is parallel to the bearing surface of the material bin 91.

[0046] For example, the taking and placing mechanism 2 can be fixedly connected to the end of the taking and placing mechanism 2 connected by the connecting member 32. Since the taking and placing mechanism 2 is fixed to the connecting member 32, in order to make the bearing surface of the taking and placing mechanism 2 and the bearing surface of the material bin 91 meet the parallel condition, the bearing surface of the taking and placing mechanism 2 and the bearing surface of the material bin 91 need to be in a parallel state for a long time, so the end of the taking and placing mechanism 2 connected by the connecting member 32, the bearing surface of the taking and placing mechanism 2 and the bearing surface of the material bin 91 are all parallel to each other. At this time, in order to make the taking and placing mechanism 2 be able to take the frame 6, the frame 6 to be taken needs to be placed parallel to the bearing surface of the material bin 91. That is, in this arrangement, the end of the taking and placing mechanism 2 connected by the connecting member 32, the bearing surface of the taking and placing mechanism 2, the frame 6 to be taken and the bearing surface of the material bin 91 are all parallel to each other.

[0047] The taking and placing mechanism 2 can also be rotationally connected to the connecting piece 32 at one end of the connecting piece 32 connecting the taking and placing mechanism 2. Since the taking and placing mechanism 2 and the connecting piece 32 can rotate relative to each other, when the taking and placing mechanism 2 takes the frame 6, an angle can be formed between the bearing surface of the taking and placing mechanism 2 and the bearing surface of the bin 91. When the taking and placing mechanism 2 places the frame 6 in the bin 91, the taking and placing mechanism 2 is rotated relative to the connecting piece 32, so that the bearing surface of the taking and placing mechanism 2 is parallel to the bearing surface of the bin 91, so that the bearing surface of the taking and placing mechanism 2 and the bearing surface of the bin 91 satisfy the parallel condition, thereby facilitating the taking and placing mechanism 2 to place the taken frame 6 in the bin 91. At this time, since the taking and placing mechanism 2 is rotated relative to the connecting piece 32, the taking and placing mechanism 2 can take the frame 6 placed at any angle, so the frame 6 to be taken can be parallel to the bearing surface of the bin 91 or form an angle with the bearing surface of the bin 91. That is, in this arrangement, the end of the connecting piece 32 connecting the taking and placing mechanism 2 is parallel to the bearing surface of the bin 91.

[0048] In the embodiments of the present disclosure, referring to FIG. 5, the taking and placing mechanism 2 includes a first base body 21 and a taking and placing assembly 23, the first base body 21 is configured to bear and connect the taking and placing assembly 23, and the number of the taking and placing assembly 23 can be one or multiple. When the number of the taking and placing assembly 23 is multiple, the multiple taking and placing assemblies 23 are arranged in sequence on the first base body 21. Moreover, each taking and placing assembly 23 can take and place one frame 6, so that when the number of the taking and placing assembly 23 is multiple, the taking and placing mechanism 2 can take and place multiple frames 6 at one time, thereby improving the feeding efficiency of the feeding device.

[0049] The first base body 21 includes a first base 211 and a second base 212, the first base 211 is fixedly connected with the second base 212, and the connecting piece 32 is connected to the first base 211, and the taking and placing assembly 23 is connected to the second base 212. The first base 211 is configured to adapt to the structure of the connecting piece 32, for example, the first base 211 can be configured as a connecting block corresponding to the position of the connecting piece 32, and the second base 212 is configured to adapt to the structure of the taking and placing assembly 23, for example, the second base 212 can be configured as a frame structure, so as to improve the flexibility between the connecting piece 32 and the taking and placing assembly 23, and also to reduce the weight of the first base body 21. In addition, the first base body 21 can also be integrally configured as a plate structure, a frame structure, etc.

[0050] In addition, the taking and placing assembly 23 includes a main body 231 and a taking and placing piece 232, the main body 231 is connected to the second base 212, and the taking and placing piece 232 is connected to the main body 231, and the number of the taking and placing piece 232 can be one or multiple. When the number of the taking and placing piece 232 is multiple, the multiple taking and placing pieces 232 are arranged at intervals on the main body 231. Moreover, the taking and placing piece 232 can be configured as a claw, a suction cup, etc., which is not limited in the present disclosure.

[0051] The feeding device provided by the embodiments of the present disclosure can drive the taking and placing mechanism 2 to move at least along the preset direction to approach or move away from the feeding position, so as to place the frame 6 taken by the taking and placing mechanism 2 in the stock bin 91 of the feeding position, thereby realizing the automatic feeding process of the frame 6. Therefore, compared with the manual feeding process in the related art, the feeding efficiency of the feeding device in the embodiments of the present disclosure is higher. In addition, the moving mechanism 3 includes the connecting piece 32 arranged in a bent manner, so that the bearing surface of the taking and placing mechanism 2 and the bearing surface of the stock bin 91 satisfy the parallel condition, that is, the connecting piece 32 arranged in a bent manner facilitates the bearing surface of the taking and placing mechanism 2 to be parallel to the bearing surface of the stock bin 91 arranged in an inclined manner, so as to facilitate the taking and placing mechanism 2 to place the frame 6 at the bearing surface of the stock bin 91. Compared with the feeding device with a complex structure in the related art, the feeding device in the embodiments of the present disclosure is provided with the connecting piece 32 arranged in a bent manner, which facilitates the bearing surface of the taking and placing mechanism 2 to be parallel to the bearing surface of the stock bin 91 arranged in an inclined manner, so as to reduce the complex structure such as a joint structure and a spherical hinge structure for enabling the frame 6 to be placed in the stock bin 91 arranged in an inclined manner, thereby reducing the structural complexity of the feeding device. Therefore, the feeding device in the embodiments of the present disclosure has a relatively simple structure and a relatively high feeding efficiency.

[0052] Referring to FIG. 6, in some possible embodiments of the present disclosure, the feeding device further includes a reversing mechanism 4 connected between the connecting piece 32 and the taking and placing mechanism 2. The reversing mechanism 4 includes a first rotating assembly 41, and the taking and placing mechanism 2 and the connecting piece 32 are relatively rotated through the first rotating assembly 41, so that the bearing surface of the taking and placing mechanism 2 faces or faces away from the stock bin 91.

[0053] In the embodiments of the present disclosure, the first rotating assembly 41 includes a first driving piece and a first rotating shaft. The first driving piece is connected to the connecting piece 32 and is in transmission connection with the first rotating shaft, and is configured to drive the first rotating shaft to rotate relative to the connecting piece 32, thereby driving the taking and placing mechanism 2 arranged on the first rotating shaft to rotate relative to the connecting piece 32.

[0054] In an embodiment of the present disclosure, referring to FIGS. 7 and 8, the feeding device 8 comprises a plurality of frame group layers stacked one on another, each frame group layer comprises a plurality of frame groups, and each frame group comprises two frames 6 placed in a positive and negative manner. The first faces 61 of the two frames 6 placed in a positive and negative manner are arranged opposite to each other, and the second faces 62 are arranged towards each other, so that the first face 61 of one frame 6 in each frame group faces upwards, and the first face 61 of the other frame 6 faces downwards. When the taking and placing mechanism 2 places the frames 6 on the carrying surface of the hopper 91, the first faces 61 of all the frames 6 need to face towards the carrying surface of the hopper 91. At this time, if the taking and placing mechanism 2 takes a frame 6 with the first face 61 facing upwards, during the movement of the taking and placing mechanism 2 to the entry end of the hopper 91 (i.e. the upper right end of the hopper 91 in FIG. 4) by the moving mechanism 3, referring to FIG. 9, the taking and placing mechanism 2 is flipped upwards by the first rotating assembly 41 relative to the end of the taking and placing mechanism 2 connected to the connecting member 32, so that the carrying surface of the taking and placing mechanism 2 is parallel to the carrying surface of the hopper 91. Then, the taking and placing mechanism 2 releases the frame 6, so that the first face 61 of the frame 6 slides onto the carrying surface of the hopper 91, and the placing process of the frame 6 is completed.

[0055] If the taking and placing mechanism 2 takes a frame 6 with the first face 61 facing downwards, during the movement of the taking and placing mechanism 2 to the entry end of the hopper 91 by the moving mechanism 3, referring to FIG. 10, the taking and placing mechanism 2 is flipped downwards by the first rotating assembly 41 relative to the end of the taking and placing mechanism 2 connected to the connecting member 32, so that the carrying surface of the taking and placing mechanism 2 is parallel to the carrying surface of the hopper 91. Then, the taking and placing mechanism 2 releases the frame 6, so that the first face 61 of the frame 6 slides onto the carrying surface of the hopper 91, and the placing process of the frame 6 is completed.

[0056] In some embodiments, referring to FIGS. 2, 7 and 8, the adjacent two frame group layers of the feeding device 8 are provided with interlayer paper. The taking and placing mechanism 2 comprises a number of taking and placing assemblies 23, which is the same as the number of frames 6 placed in a positive or negative manner in each frame group layer, so that the taking and placing mechanism 2 can take or place all the frames 6 placed in a positive or negative manner in each frame group layer at a time. In the case that the taking and placing mechanism 2 takes all the frames 6 placed in a positive manner in each frame group layer, the interlayer paper can be taken up and moved to the position where the paper recycling box 14 is located, and then the taking and placing mechanism 2 is flipped by the first rotating assembly 41 relative to the end of the taking and placing mechanism 2 connected to the connecting member 32, so that the interlayer paper falls into the paper recycling box 14. This arrangement makes it unnecessary for the feeding device to additionally provide a paper taking mechanism, and thus the structure of the feeding device is simpler.

[0057] The first rotating assembly 41 is arranged to enable the relative rotation between the taking-and-placing mechanism 2 and the connecting piece 32, so that the taking-and-placing mechanism 2 can take the frame 6 in different placement angles, such as horizontally placed or placed at an angle with the horizontal plane. After the taking-and-placing mechanism 2 takes the frame 6 in different placement angles, the relative position between the taking-and-placing mechanism 2 and the connecting piece 32 can be adjusted through the first rotating assembly 41, so that the bearing surface of the taking-and-placing mechanism 2 can be parallel to the bearing surface of the material bin 91, thereby facilitating the taking-and-placing mechanism 2 to place the frame 6 on the bearing surface of the material bin 91. Moreover, after the taking-and-placing mechanism 2 takes different surfaces of different frames 6, all the frames 6 placed into the material bin 91 can also contact the bearing surface of the material bin 91 with the same side surface, for example, after the taking-and-placing mechanism 2 takes the first surface 61 or the second surface 62 of the frame 6, the taking-and-placing mechanism 2 can be rotated through the first rotating assembly 41, so that the first surface 61 of all the frames 6 placed into the material bin 91 by the taking-and-placing mechanism 2 is directed to the bearing surface of the material bin 91. Therefore, the arrangement of the first rotating assembly 41 enables the feeding device of the present disclosure to be applied to various material taking environments, thereby increasing the application scenarios of the feeding device.

[0058] Referring to FIGS. 3 and 6, in some possible embodiments of the present disclosure, the connecting piece 32 includes a first connecting section 321 connected to the taking-and-placing mechanism 2, and the rotation axis L1 of the first rotating assembly 41 is perpendicular to the central axis of the first connecting section 321, or the rotation axis L1 of the first rotating assembly 41 is parallel to the central axis of the first connecting section 321.

[0059] In the embodiments of the present disclosure, one end of the connecting piece 32 connected to the taking-and-placing mechanism 2 is the first connecting section 321. The connecting piece 32 includes the first connecting section 321 connected to the taking-and-placing mechanism 2, and a second connecting section 322 connected to the third support beam 312 of the moving assembly 31, the first connecting section 321 is fixedly connected to the second connecting section 322, and the first connecting section 321 is arranged to be bent relative to the second connecting section 322, so that the central axis of the first connecting section 321 is parallel to the bearing surface of the material bin 91.

[0060] In the embodiments of the present disclosure, referring to FIG. 6, the rotation axis L1 of the first rotating assembly 41 is perpendicular to the central axis of the first connecting section 321, that is, the rotation axis L1 of the first rotating assembly 41 is perpendicular or approximately perpendicular to the central axis of the first connecting section 321, so that the taking-and-placing mechanism 2 can be flipped up and down relative to the first connecting section 321 through the first rotating assembly 41, so that the bearing surface of the taking-and-placing mechanism 2 is parallel to the bearing surface of the material bin 91 at least during the process of placing the frame 6 into the material bin 91 by the taking-and-placing mechanism 2, thereby completing the feeding process.

[0061] In the embodiments of the present disclosure, the rotation axis L1 of the first rotating assembly 41 is parallel to the central axis of the first connecting section 321, i.e., the rotation axis L1 of the first rotating assembly 41 is parallel or approximately parallel to the central axis of the first connecting section 321, and the bearing surface of the taking-and-placing mechanism 2 is parallel to the first connecting section 321, so that the bearing surface of the taking-and-placing mechanism 2 can rotate around the first connecting section 321 through the first rotating assembly 41, i.e., the bearing surface of the taking-and-placing mechanism 2 can rotate around the first connecting section 321 in the circumferential direction thereof, so as to at least in the process of placing the frame 6 into the bin 91 by the taking-and-placing mechanism 2, the bearing surface of the taking-and-placing mechanism 2 is parallel to the bearing surface of the bin 91, thereby completing the feeding process. It should be noted that since the bearing surface of the taking-and-placing mechanism 2 can rotate around the first connecting section 321 in the circumferential direction thereof, i.e., the taking-and-placing mechanism 2 cannot be flipped up and down relative to the first connecting section 321, the taking-and-placing mechanism 2 is difficult or impossible to take the frame 6 placed at an angle to the bearing surface of the taking-and-placing mechanism 2, and therefore, in this arrangement, the frame 6 to be taken is parallel to the bearing surface of the taking-and-placing mechanism 2.

[0062] In the technical solutions of the embodiments of the present disclosure, when the rotation axis L1 of the first rotating assembly 41 is perpendicular to the central axis of the first connecting section 321, the taking-and-placing mechanism 2 can be flipped up and down relative to the first connecting section 321, and when the rotation axis L1 of the first rotating assembly 41 is parallel to the central axis of the first connecting section 321, the taking-and-placing mechanism 2 can rotate around the first connecting section 321, and these two different arrangements can be applied to different feeding environments, so that the feeding device can better complete the feeding process.

[0063] Referring to FIG. 6, in some possible embodiments of the present disclosure, the reversing mechanism 4 further includes a second rotating assembly 42, which is connected between the first rotating assembly 41 and the taking-and-placing mechanism 2, and the taking-and-placing mechanism 2 and the first rotating assembly 41 rotate relative to each other through the second rotating assembly 42, and the rotation axis L2 of the second rotating assembly 42 is perpendicular to the bearing surface of the taking-and-placing mechanism 2.

[0065] In the embodiments of the present disclosure, the rotation axis L2 of the second rotating assembly 42 is perpendicular to the bearing surface of the taking-and-placing mechanism 2, i.e., the rotation axis L2 of the second rotating assembly 42 is perpendicular or approximately perpendicular to the bearing surface of the taking-and-placing mechanism 2, so that the taking-and-placing mechanism 2 can rotate around the second rotating assembly 42.

[0066] The second rotating assembly 42 is arranged to facilitate relative rotation between the taking and placing mechanism 2 and the first rotating assembly 41, so as to increase the degree of freedom of the taking and placing mechanism 2, and then, after the taking and placing mechanism 2 takes the frames 6 in different extension directions, the relative rotating position of the bearing surface of the taking and placing mechanism 2 and the first rotating assembly 41 can be adjusted through the second rotating assembly 42, so that the frames 6 taken by the taking and placing mechanism 2 are placed into the stock bin 91 in the actual required direction. Therefore, the arrangement of the second rotating assembly 42 can increase the flexibility of the feeding device, so that the feeding device can meet more application scenarios.

[0067] Referring to FIGS. 6, 11 and 12, in some possible embodiments of the present disclosure, the taking and placing mechanism 2 comprises a first base body 21 and a rectifying assembly 22 connected to the first base body 21.

[0068] It should be noted that the rectifying assembly 22 can act before the taking and placing mechanism 2 takes the frames 6, so as to eliminate the gap between the frames 6 by rectifying each frame 6 through the rectifying assembly 22, and then, in the process of taking the frames 6 by the taking and placing mechanism 2, the misalignment problem between part of the taking and placing members 232 of the taking and placing mechanism 2 and the frames 6 is reduced, so as to improve the taking efficiency.

[0069] In the embodiments of the present disclosure, the structure of the first base body 21 can refer to the description in the foregoing. Moreover, the rectifying assembly 22 is connected to the second base 212 of the first base body 21.

[0070] In the case that the rectifying member 221 moves along a direction parallel to the bearing surface of the taking and placing mechanism 2 through the moving mechanism 3, since the taking and placing mechanism 2 as a whole moves with the moving mechanism 3, if the moving mechanism 3 moves along a direction parallel to the bearing surface of the taking and placing mechanism 2, the rectifying member 221 of the taking and placing mechanism 2 can be driven to move along a direction parallel to the bearing surface of the taking and placing mechanism 2, and then the frames 6 are rectified.

[0071] In the case that the rectifying member 221 moves along the bearing surface of the taking and placing mechanism 2 relative to the first base body 21 through the first rectifying driving member, the first rectifying driving member is connected to the second base 212 of the first base body 21 and can be in an elongated state or a shortened state relative to the second base 212 along a direction parallel to the bearing surface of the taking and placing mechanism 2, so as to drive the rectifying member 221 to move along the bearing surface of the taking and placing mechanism 2 relative to the first base body 21, and then the frames 6 are rectified.

[0074] In the embodiments of the present disclosure, the second normalizing driving member 222 is connected to the second base 212 through the connecting plate 223, and the number of the connecting plate 223 can be one or multiple, and in the case of multiple connecting plates 223, the multiple connecting plates 223 are arranged at intervals.

[0075] In the embodiments of the present disclosure, the output end of the second normalizing driving member 222 extends or retracts relative to the bearing surface of the taking-and-placing mechanism 2 to drive the normalizing member 221 to extend or retract relative to the bearing surface of the taking-and-placing mechanism 2. The second normalizing driving member 222 can be a driving member outputting rotational motion, such as a motor, a rotary cylinder, etc., or a driving member outputting linear motion, such as a hydraulic cylinder, a pneumatic cylinder, an electric telescopic rod, etc., wherein the motor can be a servo motor, a stepper motor, etc. In an example, the second normalizing driving member 222 is a pneumatic cylinder, which is connected to the second base 212 through the connecting plate 223, and the output end of the pneumatic cylinder is fixedly connected to the normalizing member 221.

[0076] In the embodiments of the present disclosure, when the normalizing assembly 22 normalizes the frame 6, the second normalizing driving member 222 drives the normalizing member 221 to extend relative to the bearing surface of the taking-and-placing mechanism 2, so that the normalizing member 221 moves towards the frame 6 and contacts the frame 6, then the taking-and-placing mechanism 2 as a whole moves along a direction parallel to the bearing surface of the taking-and-placing mechanism 2 along with the moving mechanism 3, to drive the normalizing member 221 contacting the frame 6 to move along the direction parallel to the bearing surface of the taking-and-placing mechanism 2 and push the frame 6, or to drive the normalizing member 221 contacting the frame 6 to move along the bearing surface of the taking-and-placing mechanism 2 relative to the first base 21 along with the first normalizing driving member and push the frame 6, so as to normalize the frame 6. After the normalization is completed, the second normalizing driving member 222 drives the normalizing member 221 to retract relative to the bearing surface of the taking-and-placing mechanism 2. Therefore, the arrangement of the second normalizing driving member 222 can increase the flexibility of the normalizing assembly 22.

[0077] In some other embodiments, the second normalizing driving member 222 can also be omitted from the normalizing assembly 22, and the normalizing members 221 are arranged on the outer periphery of each of the taking and placing members 232 and are spaced apart from the taking and placing members 232. In addition, the normalizing members 221 are arranged to protrude relative to the taking and placing members 232 in the direction of the face of the frame 6, so that the normalizing members 221 are in contact with the frame 6 before the taking and placing members 232, and the normalizing members 221 are driven to move along the direction parallel to the bearing surface of the taking and placing mechanism 2 and push the frame 6 by the movement of the taking and placing mechanism 2 as a whole along with the movement mechanism 3, or the normalizing members 221 are driven to move along the bearing surface of the taking and placing mechanism 2 and push the frame 6 by the first normalizing driving member, so that the frame 6 is normalized by the normalizing members 221 before the taking and placing members 232 take the frame 6. After the normalization is completed, the taking and placing mechanism 2 moves as a whole along with the movement mechanism 3, so that the normalizing members 221 move to the outer periphery of the frame 6, and then the taking and placing members 232 can contact and take the frame 6.

[0078] Referring to FIG. 11, in some possible embodiments of the present disclosure, the feeding device further comprises a detection mechanism 5, the detection mechanism 5 is electrically connected with the normalizing assembly 22, and the detection mechanism 5 is configured to detect the relative position of the frame 6 to be taken and the first base 21.

[0079] In the embodiments of the present disclosure, after the detection mechanism 5 detects the relative position of the frame 6 to be taken and the first base 21, the feeding device can determine whether the frame 6 to be taken needs to be normalized according to the actual position of the frame 6 to be taken relative to the first base 21, and control the normalizing assembly 22 to normalize the frame 6 when the frame 6 to be taken needs to be normalized. Therefore, the arrangement of the detection mechanism 5 can improve the automation degree of the feeding device.

[0080] In the embodiments of the present disclosure, the detection mechanism 5 can be arranged on the first base 21 or the movement mechanism 3, which can be set according to actual needs.

[0081] In the embodiments of the present disclosure, the detection mechanism 5 can include one or more different types of sensors, which can be an image sensor such as a camera, or a distance sensor such as a size measuring instrument.

[0082] Referring to FIGS. 11 and 13, the embodiments of the present disclosure also provide a change structure applied to the feeding device in the embodiments of the present disclosure, and the taking and placing mechanism 2 of the feeding device comprises a first base 21 and at least two taking and placing assemblies 23. The change structure comprises at least two change members 7, each of the change members 7 is provided with at least two limiting portions 71 arranged at equal intervals, and the interval between any two adjacent limiting portions 71 in different change members 7 is different, and the limiting portions 71 are configured to limit the position of the taking and placing assembly 23 relative to the first base 21 one by one.

[0083] In the embodiment of the present disclosure, the number of the shape-changing members 7 included in the shape-changing structure can be two, three, etc., and the interval size between adjacent two limiting portions 71 in the plurality of shape-changing members 7 can gradually increase or gradually decrease by the same difference.

[0084] In the embodiment of the present disclosure, the opposite two sides of each shape-changing member 7 can be respectively provided with a plurality of limiting portions 71, and the interval size between adjacent two limiting portions 71 on the opposite two sides of each shape-changing member 7 is different, so that the opposite two sides of each shape-changing member 7 can respectively make the adjacent pick-and-place assemblies 23 in two different interval sizes, thereby improving the utilization rate of each shape-changing member 7.

[0085] In the embodiment of the present disclosure, the limiting portion 71 can be a clamping structure, a groove structure, etc. adapted to the pick-and-place assembly 23.

[0086] In the shape-changing structure provided by the embodiment of the present disclosure, the plurality of limiting portions 71 on each shape-changing member 7 can one-to-one correspond to limit the positions of the plurality of pick-and-place assemblies 23 relative to the first base body 21, so that when the pick-and-place mechanism 2 needs to pick and place the frames 6 of different specifications and sizes, different shape-changing members 7 in the shape-changing structure are placed on the pick-and-place mechanism 2, and each pick-and-place assembly 23 of the pick-and-place mechanism 2 is correspondingly limited at the limiting portion 71 on the different shape-changing member 7 with different interval sizes, so that the interval size between the adjacent pick-and-place assemblies 23 can be quickly changed, so that the pick-and-place mechanism 2 can pick and place the frames 6 of different specifications and sizes. Therefore, the shape-changing structure of the embodiment of the present disclosure can quickly adjust the interval between each pick-and-place assembly 23 on the pick-and-place mechanism 2, thereby improving the shape-changing efficiency of the pick-and-place mechanism 2.

[0087] Referring to FIG. 13, in some possible embodiments of the present disclosure, the limiting portion 71 includes a groove 711 opened in the shape-changing member 7, and the groove 711 is clamped and adapted to the pick-and-place assembly 23.

[0088] In the embodiment of the present disclosure, when it is necessary to adjust the interval size between the adjacent pick-and-place assemblies 23 of the pick-and-place mechanism 2, each pick-and-place assembly 23 and the second base 212 of the pick-and-place mechanism 2 are disassembled, so that each pick-and-place assembly 23 can move relative to the second base 212, and then the position of each pick-and-place assembly 23 is adjusted, so that each groove 711 of the shape-changing member 7 with the required interval size is clamped on the corresponding pick-and-place assembly 23, and then each pick-and-place assembly 23 is fixed to the second base 212, and the shape-changing member 7 placed on each pick-and-place assembly 23 is removed, thereby completing the adjustment of the interval size between the adjacent pick-and-place assemblies 23.

[0089] In the embodiment of the present disclosure, the provision of the groove 711 makes the structure of the limiting portion 71 simpler, and also makes the shape-changing process of each pick-and-place assembly 23 through each limiting portion 71 more convenient.

[0090] Referring to FIG. 1, FIG. 2, FIG. 4 and FIG. 7, the production line provided by the embodiment of the present disclosure further comprises the feeding device 8 and the processing device 9. The feeding device 8 is configured to provide the frame 6 to the feeding device. The processing device 9 comprises a hopper 91 configured to receive and process the frame 6 conveyed by the feeding device.

[0091] In the embodiment of the present disclosure, the feeding device 8 comprises a tray, a pallet truck or the like. The processing device 9 comprises a gluing platform. The frame 6 in the hopper 91 can be conveyed to the gluing platform for gluing treatment and then conveyed to the assembling equipment for frame assembly of the photovoltaic module.

[0092] In the production line provided by the embodiment of the present disclosure, the connecting piece 32 of the feeding device is connected to one end of the taking and placing mechanism 2 and the bearing surface of the hopper 91 is in parallel or approximately parallel state. During the process that the taking and placing mechanism 2 places the frame 6 on the hopper 91, the bearing surface of the taking and placing mechanism 2 can be parallel to the bearing surface of the hopper 91, so that the taking and placing mechanism 2 can place the frame 6 on the bearing surface of the hopper 91. Therefore, the feeding device in the production line of the present disclosure can reduce the complex structure such as joint structure, spherical hinge structure or the like, which is used to place the frame 6 into the hopper 91 arranged in an inclined manner, thereby reducing the structural complexity of the feeding device. In addition, the taking and placing mechanism 2 can take and place multiple frames 6 at the same time, thereby improving the feeding efficiency of the feeding device.

[0093] The feeding process of the production line is as follows: the moving mechanism 3 moves on the rack 1, drives the taking and placing mechanism 2 arranged on the moving mechanism 3 to move, until it reaches above the feeding device 8, then the first rotating assembly 41 is controlled to rotate the taking and placing mechanism 2 relative to the connecting piece 32, so that the bearing surface of the taking and placing 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 first base 21, and when it is judged that there is a gap between the adjacent frames 6 placed on the feeding device 8, the correcting assembly 22 is controlled to start working, so that the correcting piece 221 moves in the direction parallel to the bearing surface of the taking and placing mechanism 2, to eliminate the gap between the adjacent frames 6 placed on the feeding device 8, and then the correcting assembly 22 is retracted. Then the moving mechanism 3 is controlled to move relative to the rack 1 towards the feeding device 8, and each taking and placing assembly 23 of the taking and placing mechanism 2 takes the corresponding frame 6, so that the taking and placing mechanism 2 can take multiple frames 6 at a time, for example, the taking and placing mechanism 2 can take a layer of frames 6 placed on the feeding device 8 at a time. Then the moving mechanism 3 drives the taking and placing mechanism 2 to move relative to the rack 1 towards the hopper 91 of the processing device 9, and makes the taking and placing mechanism 2 approach the entrance end of the hopper 91 in the preset direction, and judges whether the bearing surface of the taking and placing mechanism 2 is parallel to the bearing surface of the hopper 91 in the process, and in the case that the bearing surface of the taking and placing mechanism 2 forms an angle with the bearing surface of the hopper 91, the first rotating assembly 41 is controlled to rotate the taking and placing mechanism 2 relative to the connecting piece 32, so that the bearing surface of the taking and placing mechanism 2 is parallel to the bearing surface of the hopper 91, and then the second rotating assembly 42 is controlled to rotate the taking and placing mechanism 2 along the circumferential direction of itself, so that the frames 6 taken by the taking and placing mechanism 2 can be placed into the bearing surface of the hopper 91 at the actual required angle. The taking and placing mechanism 2 releases the frames 6, so that the frames 6 can slide into the bearing surface of the hopper 91, and then the placing process of the frames 6 is completed.

[0094] The frame assembling device can be used for assembling a frame-containing product, and the frame-containing product can include a window, a display frame, a photovoltaic product, etc. For example, the photovoltaic product is configured to convert solar light into electric energy, and includes a first frame, a second frame, a substrate, etc. The frame assembling device is configured to assemble the first frame and the second frame onto the substrate.

[0095] In some technical solutions, when assembling the frame, the frame is prone to misalignment and sliding due to insufficient frame assembling precision. The applicant finds that, in particular when assembling a steel frame, the material of the steel frame has high weight and hardness, so that the steel frame is more prone to deviation and jamming during assembly. In the case of misalignment of the steel frame assembly, not only will the frame be damaged and the photovoltaic assembly be cracked, increasing the loss, but also the other components of the frame assembling device can be damaged, affecting the production line, thereby reducing the efficiency of the photovoltaic assembly and causing unstable quality of the assembled photovoltaic assembly.

[0096] Therefore, in order to reduce the risk of misalignment between the frames when assembling, reduce the possibility of assembly failure and component burst, and improve the assembly efficiency, the present embodiment provides an assembling device, referring to FIG. 14, FIG. 15 and FIG. 17, the assembling device comprises an assembling mechanism S1, a positioning mechanism S2 and a guide mechanism S3, wherein the positioning mechanism S2 is connected to the assembling mechanism S1, and the positioning mechanism S2 forms a limiting space for limiting the first frame K1; the guide mechanism S3 is connected to the assembling mechanism S1, and the guide mechanism S3 is arranged at the end of the limiting space, the guide mechanism S3 comprises at least one guide surface, one side of the guide surface can extend into the limiting space, and the other side of the guide surface is arranged in a direction away from the limiting space, and the guide surface is configured to guide the second frame K2 into the connecting groove K11, and the assembling device can further comprise a feeding device, the feeding device is used to provide the first frame K1 and the second frame K2 to the assembling mechanism 1.

[0097] It can be understood that the feeding device and the assembling mechanism 1 correspond to different processes of the production line, and the feeding device is located upstream of the assembling mechanism 1, and other types of production mechanisms can be arranged between the feeding device and the assembling mechanism, and the production mechanisms are used to process the frames 6 provided by the feeding device and then send them to the assembling mechanism 1. It should be noted that the first frame K1 and the second frame K2 can be the above-mentioned frame 6.

[0098] In the present embodiment, the positioning mechanism S2 forms a limiting space for limiting the first frame K1, and the positioning mechanism S2 comprises a pressing cylinder, a hooking cylinder, a pressing wheel S23, a hooking pressing block and a lower pressing block S24, referring to FIG. 16, the lower pressing block S24 is connected to the pressing cylinder, the hooking pressing block is connected to the hooking cylinder, the assembling mechanism S1 has a placing surface for placing the first frame K1, the lower pressing block S24 abuts against the upper surface of the first frame K1, and the first frame K1 is pressed tightly on the placing surface, the hooking pressing block abuts against the inner wall on one side of the first frame K1 and the base plate assembly, the lower pressing block S24, the hooking pressing block and the placing surface fix the position of the first frame K1, and the limiting space is the space where the first frame K1 is located.

[0099] In the present embodiment, referring to FIG. 15, FIG. 16 and FIG. 17, the guide mechanism S3 is arranged at the end of the limiting space, and the guide mechanism S3 is located at the end of the first frame K1, the guide mechanism S3 comprises at least one guide surface, and the at least one guide surface can guide the second frame K2 into the connecting groove K11 of the first frame K1 at the end of the first frame K1.

[0100] In the embodiment of the present disclosure, the guide surface includes a first side and a second side arranged oppositely, wherein the first side of the guide surface is arranged close to the limiting space, in order to reduce the possibility of collision between the guide surface and the first frame K1 in the limiting space, the first side of the guide surface is located outside the limiting space, and in order to enable the guide surface to provide a path for the second frame K2 to be guided into the limiting space, one side of the guide surface can extend into the limiting space, that is, the plane extending out of the first side of the guide surface can extend into the limiting space. That is, in the case that the first frame K1 is located in the limiting space, the guide surface will not collide with the first frame K1, and the guide path formed by the guide surface can guide the second frame K2 into the first frame K1.

[0101] In the embodiment of the present disclosure, the other side of the guide surface is arranged obliquely away from the limiting space, that is, the vertical distance from the second side of the guide surface to the limiting space is greater than the vertical distance from the first side of the guide surface to the limiting space, and the vertical distance is the distance between the guide surface and the limiting space along the radial direction of the limiting space. At this time, the path from the second side to the first side of the guide surface provides a guide path for the second frame K2, and the guide path is from the direction away from the limiting space to the direction close to the limiting space. When the second frame K2 reaches the first side of the guide surface under the guidance of the guide surface, it can continue to move in the direction of the first side of the guide surface into the limiting space, and the limiting space is the space where the first frame K1 is located. Therefore, the second frame K2 enters the first frame K1 under the guidance of the guide surface.

[0102] In the embodiment of the present disclosure, referring to FIGS. 15 and 17, the end of the second frame K2 is provided with a connecting piece K21, the first frame K1 has a connecting groove K11 accommodating the connecting piece K21 of the second frame K2, and the connecting piece K21 of the second frame K2 enters the connecting groove K11, thereby realizing the assembly of the first frame K1 and the second frame K2.

[0104] The assembling device of the embodiment of the present disclosure is configured to assemble the first frame K1 and the second frame K2, wherein the first frame K1 has a connecting groove K11 for accommodating the second frame K2.

Compared with the scheme in the related art in which the assembling device is prone to misalignment when assembling the frame, resulting in failure of frame assembly, and even causing the assembly to burst, affecting the efficiency of frame assembly, in the embodiment of the present disclosure, because of the limiting of the positioning mechanism S2, the position of the first frame K1 is fixed, and the guiding surface of the guiding mechanism S3 can guide the second frame K2 to smoothly enter the connecting groove K11 at the end of the first frame K1, thereby reducing the risk of misalignment between the frames during frame assembly, reducing the possibility of frame assembly failure and causing the assembly to burst, and improving the efficiency of frame assembly.

[0105] In order to improve the accuracy of the second frame K2 when assembling into the first frame K1, referring to FIG. 16 and FIG. 17, in some possible embodiments of the present disclosure, the assembling mechanism S1 forms a placing space configured to place the substrate; the positioning mechanism S2 includes a first limiting surface S21 forming a limiting space, the first limiting surface S21 faces the placing space, and the at least one guiding surface includes a first guiding surface S311 arranged away from the first limiting surface S21.
