[0002] The photovoltaic frame loader is a transport and stacking loading device that transports photovoltaic frames on a conveyor belt. When the conveyor belt transports and stacks photovoltaic frames into the loader, in order to ensure the loading efficiency of the photovoltaic frames, it is often necessary to move multiple photovoltaic frames from the conveyor belt to the loader in a horizontally centered state.

[0022] A loading method for a photovoltaic frame loader, comprising the following loading steps: T1. Before the photovoltaic frame loader performs transmission, stacking and loading of multiple photovoltaic frames, the photovoltaic frame loader is first assumed to be between the next processing station and the conveyor belt, so that the inlet and outlet ends of the photovoltaic frame loader are located at the outlet end of the conveyor belt and the inlet end of the next processing station respectively.

[0023] After completing steps T2 and T1, as the bottom photovoltaic frame enters the loading frame from the conveyor belt, the two displacement members move downward synchronously inside the loading frame through the gravity of the bottom photovoltaic frame, driving the lever to slide inside the inclined groove, so that the correction plate moves in a straight line approaching each other inside the loading frame, and finally the bottom photovoltaic frame is located in the middle part of the loading frame.

[0024] After steps T3 and T2 are completed, the transmission, stacking and loading process of other photovoltaic frames on the subsequent conveyor belt continues, thereby ensuring that the multiple photovoltaic frames are in a relatively middle position inside the loading frame.

[0025] After steps T4 and T1 to T3 are completed, the dual-axis motor is started to drive the two L-shaped translation plates to synchronously make linear motions towards each other on the inclined surfaces of the two inclined tables, so that the calibration plates respectively fixed on the sides of the two I-shaped sliders synchronously make oblique linear motions on the outside of the loading frame close to an outer side surface of the loading frame, so as to perform front-to-back alignment and leveling operations on multiple stacked photovoltaic frames.

[0026] After steps T5 and T4 are completed, the first hydraulic cylinder is started to drive the loading plate fixed to the telescopic end of the first hydraulic cylinder to move upward inside the loading frame, thereby lifting up multiple stacked photovoltaic frames that have undergone preliminary and further calibration and alignment operations.

[0027] After completing steps T6 and T5, the top photovoltaic frame is moved to the top of the two calibration plates. At this time, the first hydraulic cylinder is closed and the second hydraulic cylinder is started to push the top photovoltaic frame to the next processing position. Steps T5 to T6 are repeated until all photovoltaic frames enter a processing position one after another, and then the first hydraulic cylinder and the second hydraulic cylinder are closed.

[0028] After steps T7 and T5 to T6 are completed, the dual-axis motor is started in reverse to drive the two L-shaped translation plates to synchronously make linear motions away from each other on the inclined surfaces of the two inclined tables, so that the calibration plates respectively fixed on the sides of the two I-shaped sliders synchronously make oblique linear motions away from an outer side surface of the loading frame outside the loading frame, so as to facilitate subsequent continuous stacking and loading operations.

[0029] A U-shaped supporting top plate is fixed on the outer top of the feeding frame, a second hydraulic cylinder is fixed on the inner wall of the U-shaped supporting top plate, and a U-shaped pushing plate is fixed on the telescopic end of the second hydraulic cylinder.

[0030] The advantages of the present invention are: 1. The present invention generates a synchronous downward force on the two L-shaped baffles through the self-gravity of the photovoltaic frame at the bottom, so that the multiple guide rods slide downward in the multiple guide holes respectively, drive the two displacement members to move downward in the loading frame, and thereby provide a force for the sliding of the slide rail in the guide groove through the sliding cooperation between the inclined groove and the shifting rod, so that the two slide rails respectively make a linear motion close to each other in the two guide grooves, drive the two calibration plates to make a linear motion close to each other in the loading frame, so as to perform a preliminary left-right shifting calibration on the photovoltaic frame at the bottom layer, prevent the multiple photovoltaic frames that are mutually transmitted and stacked from offsetting inside the loading frame when other multiple photovoltaic frames are transmitted and stacked later, and prevent the left-right tilting when multiple photovoltaic frames are stacked later, so as to avoid affecting the subsequent processing process.

[0031] 2. The present invention starts a rectangular frame dual-axis motor to drive the threaded screws fixed to the two output shafts of the dual-axis motor to rotate synchronously, so that the two L-shaped translation plates synchronously make linear motions approaching each other above the inclined surfaces of the two inclined platforms, thereby driving the two moving columns to synchronously move upward on the two L-shaped translation plates through the sliding process of the two second contact balls on the inclined surfaces of the two inclined platforms respectively, so that the two cross blocks move upward on the inner walls of the two cross grooves respectively, and finally make the two I-shaped sliding blocks respectively slidingly matched in the two rectangular grooves synchronously approach one outer side surface of the loading frame, so as to perform calibration, alignment and pushing operations on multiple photovoltaic frames superimposed on each other after stacking and loading, thereby avoiding the phenomenon that the front and rear directions of multiple photovoltaic frames that have been stacked on each other are skewed during the stacking process of transmitting and loading, and avoiding the collapse of multiple photovoltaic frames superimposed on each other due to the front and rear skew during the subsequent continuous stacking and loading operations.

[0048] For example, see Figure 1-12 , the present invention provides the following technical solutions:

[0049] A photovoltaic frame feeder, specifically, comprises an installation component 1, wherein the installation component 1 has two symmetrical moving parts 2 slidingly matched inside; the installation component 1 comprises a feeding part 3, two displacement parts 4 slidingly matched on the feeding part 3 and two leveling parts 5 relatively slidingly matched on the feeding part 3, the two leveling parts 5 slidingly matched with the two displacement parts 4 respectively; the feeding part 3 comprises an installation base plate 301, a feeding frame 302 is fixed on the top of the installation base plate 301, two symmetrical U-shaped base plates 303 are fixed on the inner wall of the feeding frame 302, two symmetrical guide plates 304 are fixed on the inner wall of the feeding frame 302 above the U-shaped base plate 303, the tops of the two U-shaped base plates 303 are both provided with a flush groove 305 extending downward, the bottom of the flush groove 305 is provided with a plurality of guide holes 306 in a linear array, and the tops of the two guide plates 304 are both penetrated with a guide groove 307; The moving member 4 includes a T-shaped displacement plate 401, a placement groove 402 is opened through the top of the T-shaped displacement plate 401, a lever 403 that slides with the leveling member 5 is fixed to the inner wall of the placement groove 402, a plurality of guide rods 404 that slide in turn in a plurality of guide holes 306 are fixed to the top of the T-shaped displacement plate 401, an L-shaped baffle plate 405 is fixed to the top of the plurality of guide rods 404, a first spring 406 that is sleeved and fitted on the side surface of a guide rod 404 is fixed to the top of the T-shaped displacement plate 401, and the top of the first spring 406 is fixedly connected to the bottom of the U-shaped bottom plate 303; the leveling member 5 includes a slide rail 501 that slides in the guide groove 307, a moving plate 502 is fixed to the side of the slide rail 501, an inclined groove 503 that slides with the lever 403 is opened through the side of the moving plate 502, and a leveling plate 504 is fixed to the side of the moving plate 502.

[0050] The specific application of the first embodiment is as follows: after the installation of the entire device is completed, through the continuous feeding and conveying process of the conveyor belt, the photovoltaic frame located at the bottom first enters the interior of the device, and thereby makes a sliding fit contact with the inner top of the two L-shaped baffles 405. When the photovoltaic frame at the bottom contacts the inner top of the two L-shaped baffles 405, the gravity of the photovoltaic frame at the bottom generates a synchronous downward force on the two L-shaped baffles 405, so that the plurality of guide rods 404 slide downward in the plurality of guide holes 306 respectively, and thereby stretches the first spring 406 fixedly connected between the T-shaped displacement plate 401 and the U-shaped bottom plate 303, so that the two displacement members 4 move downward in the feeding frame 302. When the two displacement members 4 move downward in the feeding frame 302, they are connected to the lever through the inclined slot 503. The sliding cooperation between 403 provides a force for the sliding of the slide rail 501 in the guide groove 307, so that the two slide rails 501 respectively move linearly close to each other in the two guide grooves 307, thereby driving the two calibration plates 504 to move linearly close to each other in the loading frame 302, so as to perform preliminary left-right shifting calibration on the photovoltaic frame located at the bottom layer, so that the photovoltaic frame at the bottom layer can be located in the middle part of the loading frame 302 during the transmission and stacking loading process, thereby preventing the multiple photovoltaic frames that are mutually transmitted and stacked from shifting inside the loading frame 302 when other multiple photovoltaic frames are transmitted and stacked later, and preventing the left-right tilting when multiple photovoltaic frames are stacked later, thereby avoiding affecting the subsequent processing process.

[0051] For example 2, please refer to Figure 1-12, the second embodiment makes the following improvements on the basis of the first embodiment. Specifically, the movable member 2 includes a translation member 6 that slides on the loading member 3 and a calibration member 7 that slides on the translation member 6; a rectangular frame 308 is fixed on the side of the loading frame 302, and a dual-axis motor 309 is fixed on the inner wall of the rectangular frame 308.

A first contact ball 613 that is mutually fitted with the inclined surface of the first trapezoidal plate 611 is fixed on the top of the moving column 612. A support plate 614 is fixed to the bottom of the moving column 612 below the first contact ball 613. A third spring 615 that is sleeved and fitted on the side surface of the moving column 612 is fixed between the support plate 614 and the L-shaped translation plate 601. A second contact ball 616 that is mutually fitted with the inclined surface of the inclined platform 312 is fixed to the bottom of the support plate 614. The calibration member 7 includes an I-shaped slider 701 that is slidably fitted inside the rectangular groove 605. A calibration plate 702 is fixed to one side of the I-shaped slider 701. The I-shaped slider 701 is mutually fitted with the rectangular groove 605. 5, a fourth spring 703 is fixed between the I-shaped slider 701 and a bottom panel 704 is fixed to the other side thereof, a lower extension panel 705 is fixed to the side of the bottom panel 704, and a third contact ball 706 is fixed to the bottom of the lower extension panel 705; a second trapezoidal plate 617 is fixed to the side of the cross block 609, and the inclined surface of the second trapezoidal plate 617 is slidably matched with the third contact ball 706; a first hydraulic cylinder 314 is fixed to the top of the feeding frame 302 between the two inclined platforms 312, and a feeding plate 315 is fixed to the telescopic end of the first hydraulic cylinder 314; a U-shaped supporting top plate 316 is fixed to the top of the feeding frame 302, a second hydraulic cylinder 317 is fixed to the inner wall of the U-shaped supporting top plate 316, and a U-shaped pushing plate 318 is fixed to the telescopic end of the second hydraulic cylinder 317.

[0052] The specific application of the second embodiment is as follows: after completing the preliminary alignment and leveling, the feeding device starts the dual-axis motor 309 fixed to the inner wall of the rectangular frame 308, driving the threaded screw 310 fixed to the two output shafts of the dual-axis motor 309 to rotate synchronously (the thread grooves arranged on the sides of the two threaded screws 310 are symmetrical to each other), so that the two L-shaped translation plates 601 respectively connected to the two threaded screws 310 are synchronously moved closer to each other on the inclined surfaces of the two inclined platforms 312 (in the process of linear motion, the two L-shaped translation plates 601 are limited by the sliding cooperation between the limiting holes 603 respectively opened on the sides and the two limiting rods 311, so as to avoid the two L-shaped translation plates 601 from moving closer to each other when moving linearly). When the two L-shaped translation plates 601 synchronously make a linear motion approaching each other on the inclined surfaces of the two inclined platforms 312, as the two L-shaped translation plates 601 approach each other, the second contact balls 616 fixed to the bottom of the two support plates 614 synchronously slide on the inclined surfaces of the two inclined platforms 312 to fit each other, and thereby synchronously compress the third spring 615 fixedly connected between the support plate 614 and the L-shaped translation plate 601, so that the two moving columns 612 synchronously move upward on the two L-shaped translation plates 601 (when the moving column 612 moves upward on the L-shaped translation plate 601, two symmetrical vertical rails are fixed to the peripheral side surface of the moving column 612, and the hole wall on the L-shaped translation plate 601 that penetrates and slides with the moving column 612 is fixed). The inner wall is provided with two vertical grooves which are respectively slidably matched with the vertical rails to prevent the movable column 612 from rotating in the circumferential direction when it moves upward on the L-shaped translation plate 601). During the upward movement, the two cross blocks 609 are driven to move upward on the inner walls of the two cross grooves 608 respectively through the contact between the first contact ball 613 and the inclined surface of the first trapezoidal plate 611, and thereby the second spring 610 fixedly connected between the top of the cross block 609 and the inner top of the cross groove 608 is compressed synchronously. When the second spring 610 fixedly connected between the top of the cross block 609 and the inner top of the cross groove 608 is compressed, the second trapezoidal plate 617 fixed on the side of the cross block 609 moves upward synchronously. During the upward movement, the third contact ball 706 and the first trapezoidal plate 611 are connected to the second trapezoidal plate 617. The sliding fit between the inclined surfaces of the second trapezoidal plate 617 drives the two I-shaped sliders 701 respectively slidingly fitted in the two rectangular grooves 605 to synchronously approach one outer side surface of the loading frame 302, so that the fourth spring 703 fixedly connected between the I-shaped slider 701 and the rectangular groove 605 is compressed, and synchronously drives the two calibration plates 702 to approach the side surface of the photovoltaic frame, so that the other side surface of the photovoltaic frame is close to the inner wall of the two L-shaped baffles 405, and performs calibration, alignment and pushing operations on the multiple photovoltaic frames stacked after stacking and loading, so as to avoid the front and rear directions of the multiple photovoltaic frames stacked on each other being skewed during the stacking process of transmitting and loading, and to avoid the subsequent continuous stacking and loading operations.Multiple photovoltaic frames stacked on top of each other collapsed due to the phenomenon of front-to-back tilting;

[0053] Later, after a period of stacking and loading operations, the multiple photovoltaic frames that have been stacked on each other have undergone preliminary and further calibration and alignment operations, and the subsequent transmission and stacking actions are temporarily terminated. At this time, the first hydraulic cylinder 314 is started to drive the loading plate 315 fixed to the telescopic end of the first hydraulic cylinder 314 to move upward inside the loading frame 302, so as to lift up the multiple photovoltaic frames that have completed the preliminary and further calibration and alignment operations. When the top photovoltaic frame moves to above the two calibration plates 702, the first hydraulic cylinder 314 is closed, and the second hydraulic cylinder 317 is started synchronously, driving the U-shaped push plate 318 fixed to the telescopic end of the second hydraulic cylinder 317 upward. One outer side of the material frame 302 is approached until the inner wall of the U-shaped pushing plate 318 moves to the peripheral side of the uppermost photovoltaic frame, and the inner wall of the U-shaped pushing plate 318 gradually contacts the peripheral side of the uppermost photovoltaic frame. After the contact, the second hydraulic cylinder 317 is started to push out the leaked uppermost photovoltaic frame and move it to the next processing position (the next station here includes a variety of processing processes of the photovoltaic frame, which is the prior art, not shown in the figure, and will not be elaborated here), and the photovoltaic frame is subsequently processed by feeding, and the process is repeated until a plurality of photovoltaic frames stacked on each other are continuously fed and pushed out, and then the first hydraulic cylinder 314 and the second hydraulic cylinder 317 are closed;

[0054] After the stacked photovoltaic frames are continuously loaded and pushed out, the dual-axis motor 309 fixed to the inner wall of the rectangular frame 308 is started in reverse, driving the threaded screw 310 fixed to the two output shafts of the dual-axis motor 309 to rotate in the opposite direction synchronously, so that the two L-shaped translation plates 601 respectively connected to the two threaded screws 310 are synchronously moved away from each other on the inclined surfaces of the two inclined platforms 312. When the two L-shaped translation plates 601 move linearly apart, as the two L-shaped translation plates 601 approach each other, the second contact balls 616 fixed to the bottom of the two support plates 614 synchronously slide and fit on the inclined surfaces of the two inclined platforms 312, and this, combined with the elastic restoring force of the compressed third spring 615, causes the two moving columns 612 to synchronously move downward on the two L-shaped translation plates 601. In the process of moving downward, the first contact ball 613 is in contact with the inclined surface of the first trapezoidal plate 611 and the compressed third spring 615. The elastic force of the compressed second spring 610 causes the two cross blocks 609 to move downward synchronously along the inner walls of the two cross grooves 608, respectively, so that the second trapezoidal plate 617 fixed on the side of the cross block 609 moves downward synchronously. When the second trapezoidal plate 617 moves downward synchronously, through the sliding fit between the third contact ball 706 and the inclined surface of the second trapezoidal plate 617 and the elastic force of the fourth spring 703, the two I-shaped sliders 701 respectively slidingly fitted in the two rectangular grooves 605 move away synchronously toward an outer side surface of the loading frame 302, and finally the two calibration plates 702 slide downward synchronously in the process of moving away from each other, preventing the two calibration plates 702 from generating resistance to the subsequent stacking and loading process when multiple photovoltaic frames located on the surface of the conveyor belt are stacked and loaded into the interior of the entire device (the conveyor belt is a prior art and can be erected at the feed end of the device. The conveyor belt here is a prior art, not drawn in the figure, and will not be elaborated on here). This facilitates the subsequent continuous stacking and loading.

[0055] Embodiment 3, a loading method of a photovoltaic frame loader, comprising the following loading steps: T1, before the photovoltaic frame loader performs transmission and stacking loading of multiple photovoltaic frames, firstly, the photovoltaic frame loader is assumed to be between the next processing station and the conveyor belt, so that the inlet end and the outlet end of the photovoltaic frame loader are located at the outlet end of the conveyor belt and the inlet end of the next processing station in sequence;

[0056] After the steps T2 and T1 are completed, as the bottom photovoltaic frame enters the loading frame 302 from the conveyor belt, the two displacement members 4 are synchronously moved downward in the loading frame 302 by the gravity of the photovoltaic frame at the bottom, driving the lever 403 to slide in the inclined groove 503, so that the calibration plate 504 moves linearly towards each other in the loading frame 302, and finally the photovoltaic frame at the bottom is located in the middle of the loading frame 302;

[0057] After steps T3 and T2 are completed, the transmission, stacking and loading process of other photovoltaic frames on the subsequent conveyor belt continues, thereby ensuring that the multiple photovoltaic frames are in a relatively middle position inside the loading frame 302;

[0058] After steps T4 and T1 to T3 are completed, the dual-axis motor 309 is started to drive the two L-shaped translation plates 601 to synchronously make a linear motion close to each other on the inclined surfaces of the two inclined platforms 312, so that the calibration plates 702 respectively fixed on the sides of the two I-shaped sliders 701 synchronously make an oblique linear motion close to an outer side surface of the loading frame 302 outside the loading frame 302, thereby performing a front-to-back direction alignment and leveling operation on multiple stacked and loaded photovoltaic frames;

[0059] After steps T5 and T4 are completed, the first hydraulic cylinder 314 is started to drive the loading plate 315 fixed to the telescopic end of the first hydraulic cylinder 314 to move upward inside the loading frame 302, so as to lift up the multiple stacked photovoltaic frames that have undergone preliminary and further calibration and alignment operations;

[0060] After steps T6 and T5 are completed, the top photovoltaic frame is moved to the top of the two calibration plates 702. At this time, the first hydraulic cylinder 314 is closed, and the second hydraulic cylinder 317 is started to push the top photovoltaic frame to the next processing position. Steps T5 to T6 are repeated until all photovoltaic frames enter a processing position one after another, and then the first hydraulic cylinder 314 and the second hydraulic cylinder 317 are closed.

[0061] After steps T7 and T5 to T6 are completed, the dual-axis motor 309 is started in reverse, driving the two L-shaped translation plates 601 to synchronously make a straight line motion away from each other on the inclined surfaces of the two inclined tables 312, so that the calibration plates 702 respectively fixed on the sides of the two I-shaped sliders 701 synchronously make an oblique straight line motion away from an outer side surface of the loading frame 302 outside the loading frame 302, so as to carry out subsequent continuous stacking and loading operations.
