Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic manufacturing equipment technical field especially relates to a substrate correction structure and the laser induced sintering system of application thereof. BACKGROUND

[0002] In the photovoltaic manufacturing industry, the positioning accuracy requirement of laser induced sintering process equipment to solar cell is higher than other process equipment. Among them, how to ensure that the cell does not occur skew before entering the laser sintering process is one of the positioning accuracy requirements of this process to the cell. Therefore, at present, the industry generally transports the cell to the whole piece device before entering the laser sintering process, and then adjusts the position of the cell in X, Y axis two horizontal directions through the whole piece device until the cell is accurately positioned to meet the correction requirements of the subsequent laser sintering process.

[0003] The existing whole piece device mainly drives the correction roller to reciprocatingly stretch and shrink in the horizontal direction indirectly through the motor rotation to regularize the cell to the position required by the laser sintering process. The correction roller driving mechanism of the commonly used whole piece device mainly has two kinds: the motor forward rotation + reverse rotation drives the correction roller to stretch and shrink relative to the cell in the horizontal direction to complete a whole piece action, and the motor forward rotation or reverse rotation drives the correction roller to stretch and shrink relative to the cell in the horizontal direction to complete a whole piece action. Among them, the correction roller and the cell always keep relative stretching and shrinking motion in the same horizontal plane when the motor forward rotation + reverse rotation acts; in addition to driving the correction roller to stretch and shrink relative to the cell in the horizontal direction, the correction roller also drives the correction roller to ascend and descend relative to the cell in the vertical direction when the motor forward rotation or reverse rotation acts.

[0004] Since the first kind of correction roller driving mechanism only drives the correction roller to stretch and shrink in the same horizontal plane, the cell needs to be kept at a high height during the transportation of the cell to the whole piece device by the transportation device to avoid the interference between the cell and the correction roller, so the performance requirement of the transportation device is higher, which causes the production cost to increase; in addition, such device needs to perform a large amplitude retraction action to avoid the cell during transportation and then stretch out the whole piece, which reduces the production efficiency; although the second kind of correction roller driving mechanism simultaneously drives the correction roller to stretch and shrink in the horizontal and vertical directions respectively and ascend and descend, it reduces the height of the cell during transportation and the performance requirement of the transportation equipment, but the motor needs to rotate in the same direction to drive the correction roller to complete the horizontal and vertical two direction movements, which causes the dead point in the movement path of the motor, and there is a risk of jamming when the motor passes through the dead point, and the movement stroke of the motor is difficult to adjust, which cannot guarantee the positioning accuracy of the cell.

This achieves synchronous pushing and alignment of the target substrate (solar cell) in four directions. When transferring the target substrate, the linear motion components of this substrate alignment structure only need to perform a small retraction action to lower the alignment rollers to a position lower than the support plane of the target substrate. This allows the linear motion components to quickly retract and drive the alignment rollers to avoid the target substrate, thus quickly entering the next round of whole-piece operation, greatly improving production efficiency. The trajectory setting of the arc-shaped guide groove allows the height of the corresponding alignment rollers to drop slightly below the target substrate after completing the whole-piece operation, maintaining high operating efficiency while avoiding damage to the target substrate during the alignment process. In summary, the substrate correction structure provided by this utility model has the advantages of controllable stroke and smooth operation, and can achieve synchronous high-precision alignment of the target substrate from four directions.

DETAILED DESCRIPTION

[0061] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the following will further describe the present application in detail in combination with the drawings and embodiments. Figures 1-7

[0062] Please refer to Figures 1-7 The substrate correction structure provided by the present application comprises:

[0063] The base 1 is a support main body of the substrate correction structure, and can be tightly supported on a support table top or ground; the driving device 2 is used for driving the driving wheel 3 arranged on the top of the base 1 to rotate in a forward direction or a reverse direction; the four guide structures 4 are evenly and spacedly arranged on the top of the base 1 and surround the driving wheel 3, and the extending directions of the guide structures 4 all point to the driving wheel 3; the linear motion part 5 is movably arranged on the guide structures 4 along the guide structures 4; the four transmission connecting rods 6 are respectively hinged to the corresponding linear motion part 5 and the quadrant points on the periphery of the driving wheel 3; the swing guide mechanism is connected to the linear motion part 5; the connecting swing arm 8 is connected to the swing guide mechanism; the movable support 81 is arranged on the connecting swing arm 8, and the top of the movable support 81 is provided with at least one correction roller 813; the material loading device 10 is arranged between the four movable supports 81 and used for loading the target substrate.​

[0064] In the embodiment, the swing guiding mechanism comprises:

[0065] The mounting bracket 7 is arranged on the top of the base 1 and matches the guiding structure 4, and the arc-shaped guide groove 711 is arranged on the mounting bracket 7; the first rotating shaft 51 is arranged on the linear motion member 5; the second rotating shaft 72 is arranged in the arc-shaped guide groove 711 and matches the shape of the arc-shaped guide groove 711, and is movably arranged in the arc-shaped guide groove 711; and the two ends of the connecting swing arm 8 are respectively connected to the first rotating shaft 51 and the second rotating shaft 72.

[0066] When the driving device 2 drives the driving wheel 3 to rotate forward or reversely, the four linear motion members 5 are driven to reciprocate linearly along the corresponding guiding structure 4 and synchronously approach or move away from the driving wheel 3, that is, the four linear motion members 5 synchronously move centripetally or centrifugally relative to the driving wheel 3, and under the reciprocating linear motion of the linear motion member 5, one end of the connecting swing arm 8 is driven to swing up and down around the first rotating shaft 51, and under the linkage of the connecting swing arm 8, the second rotating shaft 72 reciprocates along the arc-shaped guide groove 711, thereby driving the four movable brackets 81 and the correction roller 813 connected with the corresponding connecting swing arm 8 to approach or move away from the target substrate and flip up and down.

[0067] When the correction roller 813 on the four movable brackets 81 flips up and approaches the target substrate along the movable bracket 81, the correction roller 813 on the four movable brackets 81 is used to synchronously extrude and contact the four sides of the target substrate from the four directions of the four sides of the target substrate, and the directions of the correction rollers 813 on the adjacent movable brackets 81 extruding the target substrate are 90 degrees away from each other, until the correction rollers 813 on the four movable brackets 81 are flush with the target substrate, the target substrate is synchronously pushed and extruded to the preset designated position on the loading device 10 by the correction rollers 813 on the four movable brackets 81, thereby realizing the function of the substrate correction structure to correct the relative position and attitude of the target substrate.

[0068] When the four active supports 81 are flipped down away from the target substrate until the four active supports 81 and the correction rollers 813 thereon are all below the top supporting surface of the target substrate and the carrier device 10 for carrying the target substrate, the correction rollers 813 on the four active supports 81 are simultaneously centrifuged from the four directions around the periphery of the target substrate and disengaged from the periphery of the target substrate, so that the four active supports 81 and the correction rollers 813 thereon are disengaged from the target substrate, avoiding the target substrate from being damaged or the correction from being ineffective due to the interference between the target substrate and the correction rollers 813 or the active supports 81 during the process of the target substrate being transferred from the upstream equipment to the carrier device 10 by the transfer device, or the target substrate being carried by the carrier device 10 or the moving device to the feeding device.

[0069] In the embodiment, the four guide structures 4 are guide rails, which are uniformly spaced and arranged in a cross shape on the top of the base 1 and surround and correspond to the driving wheel 3 respectively. The linear motion member 5 is a linear slider which is movably installed on the guide rails and can move towards or away from the driving wheel 3.

[0070] As a preferred embodiment of the present embodiment, the guide structure 4 is a ball linear guide rail.

[0071] As a preferred embodiment of the present embodiment, the first rotating shaft 51 is arranged in the direction perpendicular to the corresponding guide rail at one end of the linear motion member 5 close to the driving wheel 3.

[0072] The mounting bracket 7 comprises:

[0073] A pair of mounting side plates 71 are arranged in opposite directions on the top of the base 1 and parallel to the two sides of the corresponding guide rail. The arc-shaped guide groove 711 is arranged on the mounting side plate 71. The end of the arc-shaped guide groove 711 close to the driving wheel 3 is higher than the end thereof away from the driving wheel 3 (i.e. the end of the arc-shaped guide groove 711 away from the driving wheel 3 is lower than the end thereof close to the driving wheel 3). The center of the circular arc track of the arc-shaped guide groove 711 is located below the vertical plane where the arc-shaped guide groove 711 is arranged.

[0074] The second rotating shaft 72 is arranged in parallel to the first rotating shaft 51 at one end of the linear motion member 5 away from the driving wheel 3 and movably installed in the arc-shaped guide groove 711. A pair of connecting swing arms 8 are arranged between the corresponding two sides of the linear motion member 5 and the pair of mounting side plates 71. One end of one of the connecting swing arms 8 is connected to the same end of the first rotating shaft 51 and the second rotating shaft 72, and the other end thereof is connected to the opposite end of the first rotating shaft 51 and the second rotating shaft 72. One end of the other connecting swing arm 8 is connected to the same end of the first rotating shaft 51 and the second rotating shaft 72, and the other end thereof is connected to the opposite end of the first rotating shaft 51 and the second rotating shaft 72.

[0075] When the driving device 2 drives the driving wheel 3 to rotate reversely, the four linear motion members 5 are driven to move synchronously and centrifugally relative to the driving wheel 3, and the one end of the connecting swing arm 8 is driven to swing downward around the first rotating shaft 51 which moves linearly and reciprocally with the linear motion member 5, and under the linkage of the connecting swing arm 8, the second rotating shaft 72 moves downward along the arc-shaped guide groove 711 from the higher end close to the driving wheel 3 to the lower end far from the driving wheel 3, thereby driving the four movable supports 81 and the correction roller 813 which are connected to the corresponding connecting swing arm 8 to flip downward far from the target substrate, and to reach a position deeper than the top supporting surface of the target substrate and the top supporting surface of the carrier device 10 for carrying the target substrate, so as to better provide space for the transfer of the target substrate and avoid damaging the target substrate.

[0076] In other embodiments (not shown in the drawings), the swing guiding mechanism can also be provided with only one connecting swing arm 8 which is located between the linear motion member 5 and one of the mounting side plates on one side of the linear motion member 5, and the two ends of the connecting swing arm 8 are connected to the same end of the first rotating shaft 51 and the second rotating shaft 72, and the movable support 81 is mounted on the single connecting swing arm 8.

[0077] As a more preferred embodiment of the present embodiment, the highest point of the arc-shaped guide groove 711 is located between the two ends of the arc-shaped guide groove 711 close to and far from the driving wheel 3, and the highest point of the arc-shaped guide groove 711 is deviated to the end of the arc-shaped guide groove 711 close to the driving wheel 3, so that the arc-shaped guide groove 711 gradually extends and rises from the end of the arc-shaped guide groove 711 far from the driving wheel 3 to the other end close to the driving wheel 3, until the arc-shaped guide groove 711 reaches the highest point when it is close to the other end of the arc-shaped guide groove 711 close to the driving wheel 3 (without reaching the end), and then slightly drops from the highest point, and finally reaches the other end of the arc-shaped guide groove 711 close to the driving wheel 3.

[0078] Therefore, the arc-shaped guide groove 711 is higher at the end close to the driving wheel 3 than at the end away from the driving wheel 3, but the end close to the driving wheel 3 is not at the highest point of the arc-shaped guide groove 711, i.e. the end close to the driving wheel 3 is slightly lower than the highest point of the arc-shaped guide groove 711, so that in the process of the second rotating shaft 72 moving upwards along the arc-shaped guide groove 711 from the lower end away from the driving wheel 3 to the higher end close to the driving wheel 3, the four movable supports 81 and the correction roller 813 corresponding to the connecting swing arm 8 are first turned upwards close to the target substrate, and after the second rotating shaft 72 passes the highest point of the arc-shaped guide groove 711, the corresponding correction roller 813 has completed the correction of the target substrate, and at this time, the second rotating shaft 72 continues to move along the arc-shaped guide groove 711 to the end close to the driving wheel 3, which is slightly lower than the highest point of the arc-shaped guide groove 711, so that the corresponding correction roller 813 after completing the correction work reaches a position lower than the top supporting surface of the target substrate and the top supporting surface of the carrier device 10 for carrying the target substrate, avoiding damage to the target substrate in the correction process.

The opposite ends of the second rotating shaft 72 are respectively provided with a pair of rolling bearings 721.

[0087] The opposite ends of the second rotating shaft 72 are movably installed in the corresponding arc-shaped guide grooves 711 of the pair of mounting side plates 71 through the pair of rolling bearings 721, so as to reduce the wear between the rotating shaft and the mounting side plate 71 through the rolling cooperation of the rolling bearings 721 and the arc-shaped guide grooves 711, thereby prolonging the service life of the parts of the substrate correction structure. One end of the connecting swing arm 8 is provided with a third hinge hole (not shown in the figure), and the opposite end of the connecting swing arm 8 is provided with a connecting hole (not shown in the figure).

The transfer device preferably uses a vacuum chuck mechanism with XYZ three-axis linkage as its carrying mechanism, and can also use a clamping mechanism as its carrying mechanism.

[0103] In the embodiment, the driving device 2 is a driving motor mounted on the support seat plate 12. The output shaft of the driving motor vertically extends upwards above the support seat plate 12, and the above-mentioned driving wheel 3 is mounted at the top end of the output shaft in a height-adjustable manner by adjusting bolts 32, so that the height of each transmission connecting rod 6 can be adjusted to match different thicknesses of the linear motion member 5.

[0105] The correction roller 813 is flipped up to be flush with the target substrate when it is close to the target substrate to correct the target substrate, and is flipped down to be lower than the target substrate when it is away from the target substrate to receive the target substrate from the upstream device on one side of the substrate correction structure by the loading device 10 or to transfer the target substrate from the loading device 10 to the feeding device. The feeding device is used to receive the target substrate transferred from the loading device 10 by the transfer device and to transport the target substrate to the sintering device.

[0106] The utility model provides a kind of laser-induced sintering system, including sintering device (not shown in the figure) and feeding device (not shown in the figure), also including above-mentioned substrate correction structure, feeding device is located between sintering device and substrate correction structure. Above-mentioned target substrate is solar cell piece (silicon piece).

[0107] ​​​​​​When the drive device 2 (drive motor) drives the drive wheel 3 to rotate in the forward or reverse direction, it drives the four linear motion components 5 (linear sliders) to reciprocate linearly along the corresponding guide structure 4 (guide rail) to move closer to or further away from the drive wheel 3. That is, it drives the four linear motion components 5 to move synchronously towards or away from the drive wheel 3. At the same time, driven by the reciprocating linear motion of the linear motion components 5, one end of the connecting swing arm 8 is driven to swing up and down around the first rotating shaft 51 that reciprocates linearly with the linear motion components 5. Under the linkage of the connecting swing arm 8, the second rotating shaft 72 reciprocates along the arc-shaped guide groove 711, thereby driving the four movable brackets 81 and the correction rollers 813 connected to the corresponding connecting swing arms 8 to rotate up and down closer to or further away from the target substrate.

[0108] When the substrate correction structure is working, the pair of belt conveyor mechanisms 1021 of the loading device 10 first receive the target substrate from the upstream equipment on one side of the substrate correction structure.

[0109] When drive unit 2 (drive motor) rotates forward (the direction of motor rotation is...) Figures 1-2 When rotating clockwise (as in step 6), the correction rollers 813 on the four movable supports 81 are driven to rotate upwards (i.e., towards the inwards from the drive wheel 3) as the movable supports 81 approach the target substrate. The correction rollers 813 on the four movable supports 81 simultaneously press the four sides of the target substrate from four directions around the periphery. The directions in which the correction rollers 813 on adjacent movable supports 81 press the target substrate are 90 degrees to each other. When the correction rollers 813 on the four movable supports 81 are all flush with the target substrate, the target substrate is simultaneously pushed by the correction rollers 813 on the four movable supports 81 to a preset designated position on a pair of belt conveyor mechanisms 1021, thereby realizing the function of the substrate correction structure to correct the relative position and orientation (i.e., the whole substrate) of the target substrate.

[0110] After the entire piece is completed, when drive device 2 (drive motor) reverses (the direction of motor reversal is...) Figures 1-2When rotating counterclockwise (as in step 6), the correction rollers 813 on the four movable supports 81 are driven to rotate downwards (i.e., outwards from the drive wheel 3) away from the target substrate, until the four movable supports 81 and their correction rollers 813 are all below the target substrate and the top support surface of the loading device 10 used to support the target substrate. Then, the correction rollers 813 on the four movable supports 81 are simultaneously centrifuged from the four directions around the target substrate and disengaged from the four sides of the target substrate. This allows the four movable supports 81 and their correction rollers 813 to make way for the target substrate to be transferred from the loading device 10 to the feeding device and for the loading device 10 to receive the target substrate from the upstream equipment on the substrate correction structure side. This avoids interference between the target substrate and the correction rollers 813 or the movable supports 81 during the process of the transfer device transferring the target substrate from the upstream equipment to the loading device 10 and the loading device 10 driving or moving the target substrate to the feeding device, which would cause damage to the target substrate or correction failure.

[0111] At this time, a pair of belt conveyor mechanisms 1021 reciprocate linearly in sync, thereby finely adjusting the position of the target substrate in its linear motion direction to achieve secondary alignment between the target substrate and the conveying mechanism of the transfer device. Finally, the transfer device transports the calibrated target substrate from the transmission mechanism 102 to the corresponding feeding conveyor line of the feeding device on the opposite side of the substrate calibration structure, so as to transport the target substrate to the sintering device for the sintering process. Then, the pair of belt conveyor mechanisms 1021 receive the next target substrate to be calibrated from the upstream equipment, and so on, realizing batch and continuous calibration operations in the process of transporting the target substrate from the upstream equipment to the sintering device.

[0112] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Those skilled in the art should understand that any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
