Detailed Description
The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the invention and together with the description, serve to explain the principles of the invention and not to limit the scope of the invention.
FIG. 1 is a top view of a half photovoltaic module electrode detection apparatus provided in an embodiment; fig. 2 is a side view of a half-sheet photovoltaic module electrode detection apparatus provided by an embodiment. As shown in fig. 1 and 2, the half-piece photovoltaic module electrode detection apparatus provided in the embodiment includes a conveying mechanism 11, an electrode detection mechanism 12, and a first rotary lifting platform 13, and further includes a control unit 14 (not shown in fig. 1 and 2).
The conveying mechanism 11 is used for conveying the half photovoltaic module 01, and includes a conveyor belt 112 and at least two driving rollers 111, and the conveyor belt 112 runs under the driving of the driving rollers 111 or other power mechanisms. During the operation of the conveyor belt 112, the half photovoltaic module 01 placed on the conveyor belt 112 is dragged by the conveyor belt and moves from one end side of the conveyor belt 112 to the other end side.
As shown in fig. 1, a blanking area 113 is disposed in the middle of the conveyor belt 112; the empty space 113 is configured to directly communicate with the conveying surface of the conveyor belt 112 and the space below the conveyor belt 112 (it should be noted that the conveying surface is a surface of the conveyor belt 112 that can carry half of the photovoltaic module 01).
In this embodiment, the empty space 113 of the belt is an empty slot extending along the running direction of the belt 112; in some embodiments, the hollow trough may extend from one of the rollers 111 to the other roller 111 in fig. 1 and 2, and the belt 112 may directly consist of two belts running synchronously.
In other embodiments, the number of empty slots may be multiple, and adjacent empty slots are separated by the belt body that makes up the conveyor belt 112.
The electrode detection mechanism 12 is used for detecting the positive and negative electrodes of the half photovoltaic module 01 transmitted by the transmission belt and generating an electrode signal and/or a battery position signal according to the detected positive and negative electrode states.
The first rotary elevating platform 13 is provided at a lower side of the conveying surface of the belt. The first rotary elevating platform 13 has an elevating platform, an elevating driving part for driving the elevating platform to ascend or descend, and a rotary driving part for driving the elevating platform to rotate around a vertical rotation axis.
When the lifting platform in the first rotary lifting platform 13 is lifted, the lifting platform can pass through the empty letting area 113 in the conveyor belt 112, lift the half photovoltaic module 01 to be separated from the conveyor belt 112, and drive the half photovoltaic module 01 to rotate; after the half photovoltaic module 01 is rotated by a certain angle, the lifting platform is lowered so that the half photovoltaic module 01 is placed on the conveyor belt 112 again.
The control unit 14 is used for controlling the lifting state and the rotation angle of the first rotary lifting platform 13; specifically, the control unit 14 determines the lifting timing of the first rotary lifting platform 13 according to the position of the half photovoltaic assembly 01, and controls the rotation angle of the lifting platform according to the electrode signal and/or the position signal generated by the electrode detection mechanism 12.
As can be seen from the foregoing analysis, with the half photovoltaic module electrode detection apparatus provided in this embodiment, after the electrode detection mechanism 12 is used to detect and determine the positive and negative electrodes of the half photovoltaic module 01 (that is, to determine the position where the half photovoltaic module 01 is placed), the half photovoltaic module 01 can be lifted and rotated by using the first rotary lifting platform 13, so that the half photovoltaic module 01 rotates to a specific state, and the positive and negative electrodes are set according to a predetermined placement manner.
After the half photovoltaic modules 01 are arranged according to the predetermined arrangement mode, the first rotary lifting platform 13 puts the half photovoltaic modules 01 back on the conveyor belt 112. Because half a photovoltaic module 01 puts the in-process, only by first rotatory lift platform 13 lift, drive rotation and put down, so its probability that causes half a photovoltaic module 01 to damage compares and directly adopts to press from both sides and gets or when push-and-pull mode operation half a photovoltaic module 01 causes half a photovoltaic module 01 to damage the probability will be little.
It should be noted that in a specific application, in a case that the arrangement characteristics of the battery cells 01 conform to a predetermined arrangement mode, the half photovoltaic module 01 may not be lifted and rotated by the first rotary lifting platform 13; and only under the condition that the arrangement characteristics of the single batteries 01 accord with the preset arrangement mode, the half photovoltaic assembly 01 can be lifted and rotated by the first rotary lifting platform 13.
In some embodiments, the empty space 113 is an empty slot extending from one driving roller 111 to another supporting roller, and the empty slot does not interfere with the operation of the first rotating/lifting platform 13 passing through the empty slot, so that the conveyor belt 112 can always run at a certain speed.
In some embodiments, the empty space 113 is a plurality of spaced apart empty spaces that may interfere with the operation of the first rotary lift platform passing therethrough, so that the conveyor belt 112 needs to stop operating when the first rotary lift platform 13 passes through the empty spaces. Of course, in some example applications, the conveyor belt 112 may also operate at a constant speed if the location and operational characteristics of the slot do not interfere with the operation of the first rotary lift platform 13.
It is contemplated that in some embodiments, the aforementioned spaced-apart clearance slots may be replaced with clearance holes, and the shape of the clearance holes may be any shape as long as the platform of the first rotary elevating platform 13 can pass through.
It should be noted that, regardless of whether the blank area 113 is a blank slot or a blank hole, the blank area 113 should be set according to the size of the half photovoltaic module 01 to prevent the half photovoltaic module 01 from falling off the blank area 113.
In some embodiments of the present description, the first rotary elevating platform 13 can also move synchronously with the conveyor belt 112 in the first direction; the aforementioned first direction is the direction of travel of the drive belt.
It is conceivable that, because the first rotary lifting platform 13 and the conveyor belt 112 move synchronously, the first rotary lifting platform 13 and the half photovoltaic module 01 placed on the conveyor belt 112 are relatively stationary in the first direction, and the probability of relative sliding between the first rotary lifting platform and the half photovoltaic module 01 in the first direction is small during the rotation of the first rotary lifting platform.
Of course, in some embodiments, the first rotary elevating platform 13 may also be provided as an elevating platform fixed with respect to the conveyor belt 112; at this time, the size of the top of the lifting platform of the first rotating platform in the first direction may need to be set to be larger, so as to ensure that the half photovoltaic module 01 is not lifted and dropped when the half photovoltaic module 01 is lifted and lifted.
In the embodiment of the present specification, in order to facilitate the electrode detection mechanism 12 to detect the positive and negative electrodes of the half photovoltaic module 01, the half photovoltaic module 01 is firstly placed on the conveyor belt 112 according to a predetermined requirement. The aforementioned predetermined conditions may include: the photovoltaic module halves are disposed at specific positions of the conveyor belt 112 (for example, disposed on the upper side of the vacant areas 113), and the long sides or the wide sides of the photovoltaic module halves 01 are parallel to the conveying direction of the conveyor belt 112.
To achieve the object mentioned in the previous paragraph, in some embodiments, the half-sheet photovoltaic module electrode detection apparatus may further include a pre-tilt mechanism. A pre-placement mechanism is arranged upstream of the electrode detection mechanism 12 for placing the half photovoltaic modules 01 on the conveyor belt 112 according to the aforementioned predetermined requirements.
In one embodiment, the pre-placement mechanism includes a visual detection component and a position adjustment mechanism.
The visual inspection means is used to photograph the half piece of the photovoltaic module 01 placed on the conveyor belt 112 and whose position is to be adjusted, and to generate photographic data. In a specific application, the visual detection component may be a camera for detecting light of a specific frequency band. In order to realize that the visual detection part can more accurately determine the position of the half piece of photovoltaic module 01, the surface of the conveyor belt 112 can be coated with a specific material which is different from the reflection characteristic of the half piece of photovoltaic module 01, so that the contrast of the image detected by the visual detection part is improved.
Correspondingly, the control unit 14 may process the shooting data sent by the visual detection component, and determine the position state and the placement state of the half photovoltaic module 01 to be adjusted, so as to generate the adjustment parameters.
The position adjusting mechanism can adjust the half photovoltaic module 01 to a position and a placing angle meeting the preset requirements according to the adjusting parameters. It should be noted that the determination of the position and the placement angle of the half photovoltaic module 01 or the related object according to the shooting data is already known in the art, and the description of the present specification is omitted here, and specific reference may be made to the related art documents.
In one embodiment, the position adjustment mechanism may be a second rotary lift platform. Like the first rotary elevating platform 13, the second rotary elevating platform also includes a rotary driving part, an elevating driving part and an elevating platform; the lifting driving part drives the lifting platform to lift the half photovoltaic module 01 to be separated from the conveyor belt 112 through the clearance area 113; the rotation driving part drives the half photovoltaic module 01 to rotate to a preset required placing angle, and after the half photovoltaic module 01 rotates to the preset required placing angle, the half photovoltaic module 01 descends to be placed on the conveyor belt 112 again.
It is conceivable that in the aforementioned embodiment, in order to use the second rotary elevating platform to rotate the half photovoltaic module 01 to the predetermined required placing angle, the half photovoltaic module 01 should be placed at a position substantially at the upper side of the vacant area 113. In practical application, the half photovoltaic module 01 can be manually placed on the upper side of the vacant area 113, and a special positioning sub-mechanism can be arranged to realize corresponding functions.
In one application, the positioning sub-mechanism is arranged at the upstream of the second rotary lifting platform and comprises two push plates which are oppositely arranged and a pushing driving mechanism which respectively drives the two push plates; both the push plates extend along the running direction of the conveyor belt 112, and the two push plates move along the direction perpendicular to the running direction of the conveyor belt 112 under the driving of the corresponding pushing driving mechanisms so as to push the half piece of photovoltaic module 01 to the corresponding area on the upper side of the vacant area 113 and enable one side edge of the half piece of photovoltaic module 01 to extend along the second direction.
Of course, in some embodiments of the present disclosure, the aforementioned second rotary lifting platform may not be provided, and only the aforementioned positioning sub-mechanism may be provided. In other embodiments, other position adjustment mechanisms known to those skilled in the art may be provided.
It should also be noted that, in the foregoing embodiment, the position adjusting mechanism is disposed upstream of the electrode detecting mechanism 12; in other embodiments, the position adjusting mechanism may be integrated with the electrode detecting mechanism 12, so as to realize the position adjustment of the half photovoltaic module 01 and identify the positive and negative electrodes of the half photovoltaic module 01.
Furthermore, in some embodiments, the electrode detection mechanism 12 may also be disposed on the table of the first rotary elevating platform 13.
Fig. 3 is a schematic diagram of the electrode detection mechanism 12 provided in the embodiment. As shown in fig. 3, the electrode detection mechanism 12 includes two probes 121, a first detection circuit and a second detection circuit; two probes 121 are used to directly contact the half-wafer photovoltaic module 01; the first detection circuit and the second detection circuit are both connected in parallel and are both connected in series with two probes 121.
The first detection circuit includes a first diode 122 and a first voltage dividing resistor 123; the second detection circuit includes a second diode 124 and a second voltage-dividing resistor 125; the first diode 122 and the second diode 124 are turned on in opposite directions. It is conceivable that when the two probes 121 contact the positive and negative electrodes of the half-piece of photovoltaic module 01, respectively, only one of the first and second detection circuits can be turned on because the two diodes are turned on in opposite directions, so that only one of the first and second voltage-dividing resistors 123 and 125 has a voltage drop across it.
The control unit 14 is connected to two ends of the first voltage-dividing resistor 123 and the second voltage-dividing resistor 125, respectively, and determines the positive and negative electrodes of the half photovoltaic module 01 according to voltages at two ends of the first voltage-dividing resistor 123 and the second voltage-dividing resistor 125. Specifically, if a voltage difference exists between two ends of the first voltage-dividing resistor 123, it is determined that the conduction direction of the first diode 122 is the current flowing direction, and the forward access end of the first diode 122 is connected with the anode of the half photovoltaic module 01; similarly, if a voltage difference exists between the two ends of the second voltage-dividing resistor 125, the conduction direction of the second diode 124 is determined as the current flowing direction, and the forward-direction access terminal of the second diode 124 is connected with the anode of the half photovoltaic module 01.
In this specification, since the half photovoltaic module 01 itself is a power source, the electrode detection mechanism 12 may not be provided with a power source, and the circuit may be turned on by using the voltage generated by the half photovoltaic module 01 itself. In order to ensure that the intensity of the output current of the half photovoltaic module 01 is such that a specific voltage difference is formed between the two ends of the first divider resistor 123 or the second divider resistor 125, the half photovoltaic module electrode detection apparatus may further include a light source for illuminating the half photovoltaic module 01 when the electrode detection mechanism 12 detects the positive and negative electrodes of the half photovoltaic module 01.
In other embodiments, instead of the light source, a first power source may be provided in the first detection circuit and a second power source may be provided in the second detection circuit. It should be noted that the output voltage of the first power source is in the same direction as the conduction direction of the first diode 122, and the output voltage of the second power source is in the same direction as the conduction direction of the second diode 124.
In practical application, the detection device of the embodiment of the application can be arranged between a laminating station and a junction box installation station of a half photovoltaic assembly production line, after the assembly completes a laminating process, the assembly is transferred to the detection device of the embodiment of the application, the anode and the cathode of a bus bar leading-out end are detected through the detection device, the assembly is controlled to rotate by a certain angle according to the anode and cathode positions of the bus bar leading-out end, then the assembly is transferred to the junction box installation station, and the anode and cathode positions of the bus bar leading-out end of each assembly reaching the junction box installation station are consistent, so that the junction box is convenient to install.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention.
