Description

Technical Field

[0001] The present invention relates to the technical field of feeding and conveying, and more particularly to a photovoltaic frame feeding machine and a feeding method thereof. Background Art

[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, multiple photovoltaic frames need to be moved from the conveyor belt to the loader in a horizontally centered state.

[0003] Currently, photovoltaic frame loaders on the market often have the following technical problems when transferring and stacking multiple photovoltaic frames on a conveyor belt:

[0004] When the existing photovoltaic frame loader transports, stacks and loads the photovoltaic frames on the conveyor belt, it cannot ensure that the photovoltaic frames entering the photovoltaic frame loader on the conveyor belt are in the center position in the photovoltaic frame loader, and thus the correction effect cannot be achieved, resulting in a certain degree of skewness in multiple photovoltaic frames in the later row when completing the transport, stacking and loading, which affects the subsequent processing process. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a photovoltaic frame loader and a loading method that can perform preliminary and further forward, backward, left and right movement calibration on multiple stacked photovoltaic frames, so as to prevent the multiple photovoltaic frames that are stacked and loaded from offsetting inside the loading frame during the subsequent transmission, stacking and loading, thereby avoiding the impact on the subsequent processing process.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A photovoltaic frame loader comprises a mounting assembly, wherein two symmetrical moving parts are slidably fitted inside the mounting assembly.

[0008] The installation assembly includes a loading piece, two displacement pieces that are slidably fitted on the loading piece, and two leveling pieces that are relatively slidably fitted on the loading piece.

[0012] The present invention is further configured as: The moving component includes a translation member that is slidably engaged with the feeding member and a calibration member that is slidably engaged with the translation member.

[0013] A rectangular frame is fixed to the side of the feeding frame. A dual-axis motor is fixed to the inner wall of the rectangular frame. Threaded lead screws are fixed to both output shafts of the dual-axis motor. Limiting rods are fixed to opposite sides of the rectangular frame.

[0014] The present invention is further configured as: The translation member includes an L-shaped translation plate. A threaded hole and a limiting hole are sequentially formed through the side of the L-shaped translation plate. The threaded hole and the limiting hole are sequentially slidably engaged with the threaded lead screw and the limiting rod.

[0015] Two symmetric inclined platforms are fixed to the inner bottom of the feeding frame below the two L-shaped baffles. Side baffles are fixed to opposite sides of the two inclined platforms.

[0016] The present invention is further configured as: An L-shaped extension plate is fixed to the outer top of the L-shaped translation plate outside the feeding frame. A rectangular groove is formed through the outer top of the L-shaped extension plate. Connecting frames are fixed to opposite outer sides of the L-shaped extension plate. A column is fixed to the outer bottom of the connecting frame. A cross groove that extends upward is formed at the bottom of the column.

[0017] The present invention is further configured as: A cross block is slidably engaged inside the cross groove. A second spring is fixed between the top of the cross block and the inner top of the cross groove. A first trapezoidal plate is fixed to the bottom of the cross block;

[0018] A moving column is slidably engaged through the outer top of the L-shaped translation plate below the first trapezoidal plate. A first contact ball that is mutually attached to the inclined surface of the first trapezoidal plate is fixed to the top of the moving column. A support plate is fixed to the bottom of the moving column below the first contact ball. A third spring that is sleeved and engaged with the peripheral side of the moving column is fixed between the support plate and the L-shaped translation plate. A second contact ball that is mutually attached to the inclined surface of the inclined platform is fixed to the bottom of the support plate.

[0019] The present invention is further configured such that: the calibration member includes an I-shaped slider slidably fitted inside the rectangular groove, a calibration plate is fixed to one side surface of the I-shaped slider, a fourth spring is fixed between the I-shaped slider and the rectangular groove, a bottom plate is fixed to the opposite side surface of the I-shaped slider, a downward extension plate is fixed to the side surface of the bottom plate, and a third contact ball is fixed to the bottom of the downward extension plate.

[0020] A second trapezoidal plate is fixed to the side surface of the cross block, and the inclined surface of the second trapezoidal plate is slidably fitted with the third contact ball.

[0021] The present invention is further configured such that: a first hydraulic cylinder is fixed at the top inside the loading frame between the two inclined platforms, and a loading plate is fixed to the telescopic end of the first hydraulic cylinder.

[0022] A loading method for a photovoltaic frame loading machine includes the following loading steps: T1. Before the present photovoltaic frame loading machine performs the transmission, stacking, and loading of multiple photovoltaic frames, the present photovoltaic frame loading machine is first erected between the next processing station and the conveyor belt, such that the inlet end and the outlet end of the present photovoltaic frame loading machine are sequentially located at the outlet end of the conveyor belt and the inlet end of the next processing station.

[0023] After the step of T1 is completed, as the bottommost photovoltaic frame enters the inside of the loading frame from the conveyor belt, due to the self-gravity of the bottommost photovoltaic frame, the two displacement members synchronously move downward inside the loading frame, driving the lever to slide inside the inclined groove, causing the calibration plates to perform a linear motion of approaching each other inside the loading frame, and finally making the bottommost photovoltaic frame located at the middle part of the loading frame.

[0024] After the step of T2 is completed, the subsequent transmission, stacking, and loading process of other photovoltaic frames on the conveyor belt continues for transmission, stacking, and loading, so as to ensure that multiple photovoltaic frames are located at relatively intermediate positions inside the loading frame.

[0025] After the steps of T1 to T3 are completed, the dual-axis motor is started, driving the two L-shaped translation plates to synchronously perform a linear motion of approaching each other above the inclined surfaces of the two inclined platforms, causing the calibration plates respectively fixed to the side surfaces of the two I-shaped sliders to synchronously perform an oblique linear motion of approaching an outer side surface of the loading frame outside the loading frame, so as to perform an alignment and leveling operation in the front-rear direction on multiple stacked and loaded photovoltaic frames.

[0026] After the step of T4 is completed, the first hydraulic cylinder is started, driving the loading plate fixed to the telescopic end of the first hydraulic cylinder to move upward inside the loading frame, so as to lift multiple stacked photovoltaic frames that have been initially and further calibrated and aligned.

[0027] After completing steps T6 and T5, the top photovoltaic frame moves 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 into the next processing position. Steps T5 to T6 are repeated until all photovoltaic frames have entered the next processing position one after another, and then the first and second hydraulic cylinders are closed.

[0028] After steps T7 and T5 to T6 are completed, the dual-axis motor is started in the reverse direction 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 fixed on the sides of the two I-shaped sliders synchronously make oblique linear motions away from one outer side surface of the loading frame outside the loading frame, so as to carry out 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, driving the two displacement parts to move downward in the loading frame, and thereby providing 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, driving the two calibration plates to make a linear motion close to each other in the loading frame, so as to perform preliminary left and right shifting calibration on the photovoltaic frame at the bottom layer, preventing the multiple photovoltaic frames that are mutually transmitted and stacked from offsetting inside the loading frame when other multiple photovoltaic frames are later transferred, stacked and loaded, and preventing the left and right tilting when multiple photovoltaic frames are later stacked and loaded, thereby avoiding affecting the subsequent processing process.

[0031] 2. By starting the rectangular frame biaxial motor of the present invention, the threaded lead screws fixed to the two output shafts of the biaxial motor are driven to rotate synchronously, so that the two L-shaped translation plates move linearly closer to each other above the inclined surfaces of the two inclined surface platforms synchronously. In this way, through the sliding processes of the two second contact balls on the inclined surfaces of the two inclined surface platforms respectively, the two moving columns are driven to move upward on the two L-shaped translation plates synchronously, so that the two cross blocks move upward on the inner walls of the two cross grooves respectively. Furthermore, finally, the two I-shaped sliders slidingly fitted inside the two rectangular grooves move synchronously towards an outer side surface of the feeding frame, so as to perform a calibration and alignment pushing operation on multiple stacked photovoltaic frames after stacking and feeding. This avoids the phenomenon that the front and rear directions of multiple stacked photovoltaic frames are skewed during the stacking process of transmission and feeding, and avoids the collapse of multiple superimposed photovoltaic frames due to the front and rear skew phenomenon during the subsequent continuous stacking and feeding operation.

[0048] Example 1, please refer to Figures 1-12 , the present invention provides the following technical solutions:

[0049] A photovoltaic frame loading machine. Specifically, it includes an installation component 1, and two symmetrical moving components 2 are slidably fitted inside the installation component 1; the installation component 1 includes a loading component 3, two displacement components 4 slidably fitted on the loading component 3, and two leveling components 5 slidably fitted relative to each other on the loading component 3. The two leveling components 5 are respectively slidably fitted with the two displacement components 4; the loading component 3 includes an installation bottom plate 301, a loading frame 302 is fixed on the top of the installation bottom plate 301, two symmetrical U-shaped bottom plates 303 are fixed on the inner wall of the loading frame 302, two symmetrical guide plates 304 are fixed on the inner wall of the loading frame 302 above the U-shaped bottom plates 303. Downward extending flush grooves 305 are opened at the top of the two U-shaped bottom plates 303, and a number of guide holes 306 are linearly arranged at the bottom of the flush grooves 305. Guide grooves 307 are opened through the top of the two guide plates 304; the displacement component 4 includes a T-shaped displacement plate 401, an installation groove 402 is opened through the top of the T-shaped displacement plate 401, a dial rod 403 slidably fitted with the leveling component 5 is fixed on the inner wall of the installation groove 402, a number of guide rods 404 are fixed on the top of the T-shaped displacement plate 401 and are sequentially slidably fitted inside a number of guide holes 306, an L-shaped baffle 405 is fixed on the top of the number of guide rods 404, a first spring 406 sleeved on the circumferential side of a guide rod 404 is fixed on the top of the T-shaped displacement plate 401, and the top end of the first spring 406 is fixedly connected to the bottom of the U-shaped bottom plate 303; the leveling component 5 includes a slide rail 501 slidably fitted inside the guide groove 307, a moving plate 502 is fixed on the side of the slide rail 501, an inclined groove 503 slidably fitted with the dial rod 403 is opened through the side of the moving plate 502, and a leveling plate 504 is fixed on the side of the moving plate 502.

[0050] The specific application of the first embodiment is as follows: After the entire device is installed, during the continuous feeding and conveying process of the conveyor belt, the photovoltaic frame at the bottom first enters the device, and then slides and fits with the inner tops of the two L-shaped baffles 405. When the photovoltaic frame at the bottom contacts the inner tops of the two L-shaped baffles 405, due to the self-gravity of the bottom photovoltaic frame, a synchronous downward force is generated on the two L-shaped baffles 405, causing several guide rods 404 to slide downward inside several guide holes 306 respectively, and thereby stretching the first spring 406 fixedly connected between the T-shaped displacement plate 401 and the U-shaped bottom plate 303, causing the two displacement members 4 to move downward inside the feeding frame 302. When the two displacement members 4 move downward inside the feeding frame 302, through the sliding fit between the inclined slot 503 and the lever 403, a force is provided for the sliding of the slide rail 501 inside the guide slot 307, causing the two slide rails 501 to perform a linear motion of approaching each other inside the two guide slots 307 respectively, thereby driving the two calibration plates 504 to perform a linear motion of approaching each other inside the feeding frame 302, so as to initially calibrate the photovoltaic frame at the bottom layer in the left-right direction, enabling the photovoltaic frame at the bottom layer to be located in the middle of the feeding frame 302 during the process of transmission stacking and feeding, preventing the phenomenon that the multiple photovoltaic frames stacked and fed to each other are offset inside the feeding frame 302 during the subsequent transmission stacking and feeding of other multiple photovoltaic frames, and preventing the phenomenon of left-right inclination during the subsequent stacking and feeding of multiple photovoltaic frames, and avoiding affecting the subsequent processing process.

[0052] The specific application of the second embodiment is as follows: For this feeding device, after preliminary alignment and leveling are completed, by starting the double-shaft motor 309 fixed to the inner wall of the rectangular frame 308, the threaded lead screws 310 fixed to the two output shafts of the double-shaft motor 309 are driven to rotate synchronously (the thread grooves provided on the circumferential sides of the two threaded lead screws 310 are symmetric with each other), so that the two L-shaped translation plates 601 respectively threadedly and rotationally connected to the two threaded lead screws 310 synchronously perform a linear motion of approaching each other above the inclined surfaces of the two inclined surface platforms 312 (during the linear motion, the sliding fit between the limiting holes 603 respectively penetrated through the sides of the two L-shaped translation plates 601 and the two limiting rods 311 is used for limiting, to prevent the two L-shaped translation plates 601 from rotating circumferentially when performing a linear motion of approaching each other). When the two L-shaped translation plates 601 synchronously perform a linear motion of approaching each other above the inclined surfaces of the two inclined surface platforms 312, as the two L-shaped translation plates 601 approach each other, the second contact balls 616 respectively fixed to the bottoms of the two support plates 614 synchronously slide on the inclined surfaces of the two inclined surface platforms 312 and fit together, and thereby the third springs 615 fixedly connected between the support plates 614 and the L-shaped translation plates 601 are synchronously compressed, so that the two moving columns 612 synchronously move upward on the two L-shaped translation plates 601 respectively (when the moving column 612 moves upward on the L-shaped translation plate 601, two symmetric vertical rails are fixed to the circumferential side of the moving column 612, and vertical grooves respectively slidably engaged with the vertical rails are provided on the inner wall of the hole of the L-shaped translation plate 601 penetrated and slidably engaged therewith, to prevent the moving column 612 from rotating circumferentially when moving upward on the L-shaped translation plate 601). During the upward movement, through the contact action between the first contact ball 613 and the inclined surface of the first trapezoidal plate 611, the two cross-shaped blocks 609 are driven to move upward on the inner walls of the two cross-shaped grooves 608 respectively, and thereby the second springs 610 fixedly connected between the tops of the cross-shaped blocks 609 and the inner tops of the cross-shaped grooves 608 are synchronously compressed. When the second springs 610 fixedly connected between the tops of the cross-shaped blocks 609 and the inner tops of the cross-shaped grooves 608 are compressed, the second trapezoidal plates 617 fixed to the sides of the cross-shaped blocks 609 move upward synchronously. During the upward movement, through the sliding and fitting action between the third contact ball 706 and the inclined surface of the second trapezoidal plate 617, the two I-shaped sliders 701 respectively slidably engaged inside the two rectangular grooves 605 are driven to approach the outer side of the feeding frame 302 synchronously, so that the fourth springs 703 fixedly connected between the I-shaped sliders 701 and the rectangular grooves 605 are compressed, and the two calibration plates 702 are synchronously driven to approach the side of the photovoltaic frame, so that the opposite side of the photovoltaic frame approaches the inner walls of the two L-shaped baffles 405, and a calibration and alignment pushing operation is performed on multiple superposed photovoltaic frames after stacking and feeding, to avoid the phenomenon that the front and rear directions of multiple stacked photovoltaic frames are skewed during the stacking process of transmission and feeding, and to avoid subsequent continuous stacking and feeding operations,Multiple mutually stacked photovoltaic frames collapsed due to the phenomenon of tilting forward and backward;

[0053] After a period of stacking and loading operations in the later stage, after multiple mutually stacked photovoltaic frames are initially and further calibrated and aligned, the subsequent transfer and stacking actions are temporarily terminated. At this time, the first hydraulic cylinder 314 is started, driving the loading plate 315 fixed to the telescopic end of the first hydraulic cylinder 314 to move upward inside the loading frame 302, thereby lifting multiple mutually stacked photovoltaic frames that have been initially and further calibrated and aligned upward until the topmost photovoltaic frame moves above the two calibration plates 702. Then, the first hydraulic cylinder 314 is closed, and simultaneously, the second hydraulic cylinder 317 is started, driving the U-shaped pushing plate 318 fixed to the telescopic end of the second hydraulic cylinder 317 to approach an outer side of the loading frame 302 until the inner wall of the U-shaped pushing plate 318 moves to the circumferential side of the topmost photovoltaic frame and the inner wall of the U-shaped pushing plate 318 gradually contacts the circumferential side of the topmost photovoltaic frame. After contact, the second hydraulic cylinder 317 is continuously started to push out the exposed topmost photovoltaic frame and move it to the next processing site (the next station here includes various processing processes of the photovoltaic frame, which is prior art and not shown in the figure and will not be elaborated here too much), and subsequent loading and processing of the photovoltaic frame are carried out. In this way, until multiple mutually stacked photovoltaic frames are continuously loaded and pushed out, the first hydraulic cylinder 314 and the second hydraulic cylinder 317 are closed;

[0054] After the above-mentioned multiple stacked photovoltaic frames are continuously fed and pushed out, the biaxial motor 309 fixed to the inner wall of the rectangular frame 308 is started in reverse, driving the threaded lead screws 310 fixed to the two output shafts of the biaxial motor 309 to rotate in reverse synchronously, so that the two L-shaped translation plates 601 respectively threadedly connected to the two threaded lead screws 310 move linearly away from each other above the inclined surfaces of the two inclined surface platforms 312 synchronously. When the two L-shaped translation plates 601 move linearly away from each other above the inclined surfaces of the two inclined surface platforms 312 synchronously, as the two L-shaped translation plates 601 approach each other, the second contact balls 616 respectively fixed to the bottoms of the two support plates 614 slide and fit with each other on the inclined surfaces of the two inclined surface platforms 312 synchronously, and combined with the elastic restoring force of the compressed third spring 615, the two moving columns 612 move downward on the two L-shaped translation plates 601 respectively synchronously. During the downward movement, through the contact action between the first contact ball 613 and the inclined surface of the first trapezoidal plate 611 and the elastic force of the compressed second spring 610, the two cross blocks 609 move downward synchronously on the inner walls of the two cross grooves 608, so that the second trapezoidal plates 617 fixed to the sides of the cross blocks 609 move downward synchronously. When the second trapezoidal plates 617 move downward synchronously, through the sliding and fitting action 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 inside the two rectangular grooves 605 move away from the outer side surface of the loading frame 302 synchronously, and finally, when the two calibration plates 702 move away from each other, they slide downward synchronously, preventing them from obstructing the subsequent stacking and feeding process when stacking and feeding multiple photovoltaic frames on the surface of the conveyor belt into the whole device (the conveyor belt is a prior art, which can be installed at the feeding end of this device. The conveyor belt here is a prior art and is not shown in the figure and will not be elaborated here), facilitating subsequent continuous stacking and feeding.

[0055] Embodiment 3, a feeding method of a photovoltaic frame feeder, includes the following feeding steps: T1. Before the photovoltaic frame feeder conveys and stacks multiple photovoltaic frames, first install the photovoltaic frame feeder between the next processing station and the conveyor belt, so that the inlet end and the outlet end of the photovoltaic frame feeder 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 of T2 and T1 are completed, as the bottommost photovoltaic frame enters the interior of the loading frame 302 from the conveyor belt, due to the self-gravity of the bottom photovoltaic frame, the two displacement members 4 move downward synchronously inside the loading frame 302, driving the lever 403 to slide inside the inclined slot 503, causing the leveling plate 504 to perform a linear motion of approaching each other inside the loading frame 302, and ultimately making the bottommost photovoltaic frame located at the middle part of the loading frame 302;

[0057] After the steps of T3 and T2 are completed, the subsequent process of transporting, stacking, and loading other photovoltaic frames on the conveyor belt continues, so as to ensure that multiple photovoltaic frames are in a relatively intermediate position inside the loading frame 302;

[0058] After the steps of T4 and T1 - T3 are completed, start the double-axis motor 309, driving the two L-shaped translation plates 601 to perform a linear motion of approaching each other synchronously above the inclined surfaces of the two inclined surface platforms 312, so that the calibration plates 702 respectively fixed on the sides of the two I-shaped sliders 701 perform an oblique linear motion of approaching one outer side of the loading frame 302 outside the loading frame 302, thereby performing an alignment and leveling operation in the front-back direction on multiple photovoltaic frames that have completed stacking and loading;

[0059] After the steps of T5 and T4 are completed, start the first hydraulic cylinder 314, driving the loading plate 315 fixed to the telescopic end of the first hydraulic cylinder 314 to move upward inside the loading frame 302, thereby lifting multiple stacked photovoltaic frames that have initially and further completed the calibration and alignment operations;

[0060] After the steps of T6 and T5 are completed, the topmost photovoltaic frame moves above the two calibration plates 702. At this time, turn off the first hydraulic cylinder 314 and start the second hydraulic cylinder 317 to push the topmost photovoltaic frame into the next processing position. In this way, repeat the steps of T5 - T6 until all photovoltaic frames have successively entered the next processing position, and then turn off the first hydraulic cylinder 314 and the second hydraulic cylinder 317;

[0061] After the steps of T7 and T5 - T6 are completed, reverse-start the double-axis motor 309, driving the two L-shaped translation plates 601 to perform a linear motion of moving away from each other synchronously above the inclined surfaces of the two inclined surface platforms 312, so that the calibration plates 702 respectively fixed on the sides of the two I-shaped sliders 701 perform an oblique linear motion of moving away from one outer side of the loading frame 302 outside the loading frame 302, in order to facilitate subsequent continuous stacking and loading operations.
