[0051] Embodiment:

[0052] Figure 1 is a structural schematic view of a layout device for a photovoltaic module provided by the utility model embodiment, as shown in Figure 1 A layout device for a photovoltaic module includes a carrier displacement module 1, a lifting module 2, a first visual camera 3 and a mechanical hand module 4.

[0053] The carrier displacement module 1 is used to transport the carrier with the conductive back plate along the first direction (for example, the X-axis direction in Figure 1 ).

[0054] Figure 2 is a structural schematic view of a lifting module provided by the utility model embodiment, Figure 3 is a side view of the lifting module provided by the utility model embodiment, as shown in Figure 1 The lifting module 2 is located at the side of the carrier displacement module 1 (the side does not include the side of the carrier displacement module 1 in the first direction, because the side in the first direction affects the carrier transmission), and the lifting module 2 includes at least one lifting unit, the lifting unit includes a driving mechanism 22 and a plurality of interval arranged adsorption tables 23, each adsorption table 23 is used to support one cell piece, and the driving mechanism 22 is used to drive the adsorption table 23 to move up and down along the vertical direction, so that each adsorption table 23 is sequentially in the position of the vertical direction higher than all other adsorption tables 23.

[0055] The first visual camera 3 is used for taking pictures of the plurality of battery pieces to obtain position information of each battery piece.

[0056] Figure 4 is a structural schematic diagram of the mechanical hand module provided by the embodiment of the utility model, as Figure 4 shown, the mechanical hand module 4 includes a mechanical hand 41 and a plurality of suction cups 42 connected to the end of the mechanical hand 41, the plurality of suction cups 42 are divided into a plurality of suction cup groups, one suction cup group corresponds to one adsorption table 23, for adsorbing one battery piece, the mechanical hand 41 is used for controlling each suction cup group to arrange the required posture on the conductive backboard and adsorb the battery piece piece by piece, and finally simultaneously carries the plurality of battery pieces to the conductive backboard. Wherein, the mechanical hand is preferably a four-axis mechanical hand.

[0057] For the layout device for photovoltaic module provided by the embodiment of the utility model, when the plurality of battery pieces is arranged on the conductive backboard, first, the carrier displacement module is used to convey the carrier carrying the conductive backboard to the specified position along the first direction, which can also be called the layout position. At the same time, the upstream mechanism transfers the plurality of battery pieces to the corresponding adsorption table respectively, at this time, the position accuracy between the battery pieces cannot meet the placement requirements. Then, the first visual camera takes pictures of the plurality of battery pieces on the plurality of adsorption tables, and transmits the position information of each battery piece to the mechanical hand, the driving mechanism drives the plurality of adsorption tables to ascend and descend, so that each adsorption table is in turn higher than all other adsorption tables in the vertical direction, when each adsorption table is in turn higher than all other adsorption tables, the mechanical hand controls each suction cup group to adsorb the battery piece piece by piece according to the required posture arranged on the conductive backboard. In this process, after the driving mechanism raises each corresponding adsorption table to a position higher than that of other adsorption tables, the mechanical hand corrects the corresponding adsorption group and adsorbs the corresponding battery piece, the mechanical hand adsorbs only one battery piece at a time, and the position of the battery piece is higher than that of other battery pieces when the battery piece is adsorbed. Before adsorption, the position adjustment of the single adsorption group has been completed, wherein the correction of the adsorption group can be regarded as the final correction of the corresponding battery piece. In this way, each suction cup group finally adsorbs the battery piece piece by piece according to the required posture arranged on the conductive backboard.

[0058] Then, when all the suction cup groups on the mechanical hand 41 adsorb the battery pieces, the mechanical hand 41 controls the plurality of suction cup groups to simultaneously and accurately transfer the plurality of adsorbed battery pieces to the conductive backboard, at this time, a plurality of battery pieces with accurate position adjustment can be transferred to the conductive backboard at a time. Repeat the above steps until the required battery pieces on the conductive backboard are all completed. After the layout is completed, the carrier displacement module 1 conveys the carrier and the conductive backboard to the downstream.

[0059] That is, the layout device for the photovoltaic module provided by the embodiment of the utility model, simple structure, low cost, cell piece only needs to be carried once by mechanical hand to complete accurate arrangement, and meanwhile, the arrangement efficiency is ensured.

[0060] Exemplarily, the mechanical hand 41 is provided with a connecting frame 43, and a plurality of suction cups 42 are arranged on the connecting frame 43 at intervals.

[0061] It is easy to understand that each suction table 23 is sequentially arranged at a position higher than all other suction tables 23 in the vertical direction, that is, when one suction table 23 is located at a certain height, other suction tables 23 are lower than the height at this time, so that the corresponding cell piece on one suction table 23 is at a high position, and the cell pieces that are temporarily not needed to be sucked or have been sucked on other suction tables 23 are at a low position, thereby enabling the corresponding suction cup group of the mechanical hand 41 to suck the cell piece, and other suction cup groups of the mechanical hand 41 do not suck other cell pieces, so as to avoid interference of other suction cups 42 with other cell pieces, ensure that the suction cup group of the mechanical hand 41 only sucks one cell piece each time, and thus ensure the accurate position of each cell piece.

[0062] It should be noted that in the embodiment, the first visual camera is electrically connected with the mechanical hand, specifically, the first visual camera transmits the position information of the cell piece obtained by photographing to the data processor, the data processor generates coordinate information after data processing, and the controller transmits the corresponding control instruction to the mechanical hand, and the mechanical hand completes the corresponding action.

[0063] Exemplarily, the suction cup group is configured such that when the adjacent suction cup groups suck the cell pieces, the distance between the adjacent cell pieces is equal to the preset distance between the adjacent cell pieces in the photovoltaic module, so as to ensure that the distance between the cell pieces reaches the distance requirement of the adjacent cell pieces in the photovoltaic module after the cell pieces are placed on the conductive back plate. The preset distance is the distance between the adjacent cell pieces in the set photovoltaic module product.

[0064] In the embodiment, the layout device is configured such that when the driving mechanism 22 drives the plurality of suction tables 23 to rise to the highest position, the first visual camera 3 visually photographs the plurality of cell pieces on the plurality of suction tables 23; and the mechanical hand 41 is configured such that when each suction table 23 rises to the highest position, the suction cup group sucks the cell piece on the suction table 23.

[0065] In the above embodiment, when the driving mechanism 22 drives the plurality of adsorption tables 23 to rise to the highest position, it is not only convenient for the suction cup group to adsorb the battery piece on the adsorption table 23, but also convenient for the driving mechanism 22 to control and drive. Moreover, when the plurality of adsorption tables 23 rise to the highest position, the first visual camera 3 takes a picture, so that the picture position and the adsorption position of the battery piece in the vertical direction are the same, and the position deviation of the battery piece in the lifting process is avoided, so that the position information of the battery piece obtained by the first visual camera is consistent with the actual position information.

[0066] In an implementation mode of the present application, Figure 5 is a structural schematic diagram of a lifting mechanism provided by an embodiment of the present application, Figure 6 is a schematic diagram of the arrangement of a plurality of cams provided by an embodiment of the present application, Figure 7 is a structural schematic diagram of a cam provided by an embodiment of the present application, in combination with Figures 5-7 As shown in the figure, the driving mechanism 22 comprises a driving executive member 221, a rotating shaft 222, a plurality of cams 223 and a plurality of cam rollers 224, the output shaft of the driving executive member 221 is in transmission connection with the rotating shaft 222, the plurality of cams 223 are spaced and sleeved on the rotating shaft 222, each cam roller 224 corresponds to one adsorption table 23 and is connected below the adsorption table 23, the edge of each cam 223 is in contact with the edge of the corresponding cam roller 224, and the driving executive member 221 drives the rotating shaft 222 to move, thereby driving the rotation of the cam 223 and driving the lifting movement of each adsorption table 23.

[0067] In the above embodiment, the driving executive member 221 drives the rotating shaft 222 to rotate, thereby driving the plurality of cams 223 to rotate, the edge of the cam 223 drives the cam roller 224 to move, and finally the plurality of adsorption tables 23 are lifted, and finally the plurality of adsorption tables 23 are sequentially arranged in the vertical direction and the position of each adsorption table 23 is higher than that of all other adsorption tables 23.

[0068] Exemplarily, the driving executive member 221 can be a motor.

[0069] Specifically, each cam 223 has a plurality of rest points, the distance between the rest points and the center of the cam 223 is different, and in the process of the cam roller 224 rolling from one rest point to another rest point, the adsorption table 23 is lifted or lowered.

[0070] It is easy to understand that each cam 223 has a plurality of rest points, and the distance between the rest points and the center of the cam 223 is different, that is, the outer diameter of the edge of the cam 223 is different, so that the plurality of cam rollers 224 move up and down according to the predetermined movement law, thereby making the plurality of adsorption tables 23 and the plurality of battery pieces move up and down according to the required position points, and ensuring that the suction cup group of the mechanical hand 41 only sucks one battery piece at the high position each time.

[0071] Further, the lifting unit further comprises a fixed support plate 21, the adsorption tables 23 can be lifted in the vertical direction along the support plate 21, and a spring is connected between each adsorption table 23 and the support plate 21, that is, one adsorption table 23 is provided with one spring, and the spring is used to make the cam roller 224 tightly adhere to the cam 223. Wherein, the support plate 21 plays a guiding role in the lifting of the adsorption tables 23, and a sliding rail can be arranged on the support plate 21, and the adsorption tables 23 are connected to the sliding rail, so that the adsorption tables 23 can smoothly move up and down, and the elastic force generated by the spring can drive the adsorption tables 23 to move towards the cam 223, so that the cam roller 224 tightly adheres to the cam 223.

[0072] Exemplarily, the lifting unit further comprises two support tables 225, and the two ends of the rotating shaft 222 are rotatably inserted into the two support tables 225, so that the rotating shaft 222 is reliably supported by the support tables 225. The adsorption tables 23 have vacuum adsorption holes, so that the battery pieces are adsorbed and fixed during the lifting of the adsorption tables 23.

[0073] The following briefly describes the states of the multiple adsorption tables 23 in sequence during the lifting process in combination with the drawings:

[0074] See Figure 8 The first state is the initial state, and the four adsorption tables 23 are at the lowest position.

[0075] See Figure 9 The rotating shaft 222 rotates by a certain angle, and the four adsorption tables 23 reach the second state, at this time, the four adsorption tables 23 are all at the highest position. At this time, the rotating shaft 222 does not rotate, and the first visual camera 3 takes a picture.

[0076] When the picture taking is completed, the driving executive 221 drives the rotating shaft 222 to continue to rotate by a certain angle, and the four adsorption tables 23 reach the third state, see Figure 10 At this time, the A adsorption table 23 is at the highest position, and the B, C and D adsorption tables 23 are lowered by a certain height, at this time, the battery pieces on the A adsorption table 23 are conveniently taken by the mechanical hand 41.

[0077] When the battery pieces on the A adsorption table 23 are taken away, the driving executive 221 drives the rotating shaft 222 to continue to rotate by a certain angle, and reaches the fourth state, see Figure 11 At this time, the B adsorption table 23 moves up to the highest position, the A adsorption table 23 moves down (not lowered to the lowest position), and the C and D adsorption tables 23 are stationary, and the multiple adsorption tables 23 reach the fourth state, at this time, the B adsorption table 23 is convenient for taking.

[0078] When the battery pieces on the B adsorption table 23 are taken away, the driving executive 221 drives the rotating shaft 222 to continue to rotate by a certain angle, and the multiple adsorption tables 23 reach the fifth state, seeFigure 12 At this time, the third time of taking out the material, the C adsorption table 23 moves upward to the highest position, the A and B adsorption tables 23 descend, and the D adsorption table 23 remains unchanged, at this time, the C adsorption table 23 is at the highest position to facilitate the robot 41 to take out the material.

[0079] When the battery piece on the C adsorption table 23 is taken away, the driving executor 221 drives the rotating shaft 222 to continue rotating by a certain angle, and the plurality of adsorption tables 23 reach the sixth state, see Figure 13 At this time, the D adsorption table 23 is the highest, and the A, B and C adsorption tables 23 descend, which is the fourth time of taking out the material. At this time, the D adsorption table 23 is at the highest position to facilitate the robot 41 to take out the material.

[0080] When the battery piece on the D adsorption table 23 is taken away, the driving executor 221 continues to rotate by a certain angle, and the cam 223 returns to the starting point, the whole action completes a cycle, and the plurality of adsorption tables 23 re-reach the first state.

[0082] In the above embodiment, each linear module is controlled by the controller, and the control of each adsorption table 23 can be realized, so that the regular ascending and descending of the plurality of adsorption tables 23 is ensured. The linear module has high precision and can ensure the precision during the ascending and descending of the adsorption table 23.

[0083] Preferably, the lifting module 2 includes a plurality of lifting units, the lifting units are arranged at intervals along the first direction or along the direction perpendicular to the first direction (i.e. the second direction, Figure 1 Correspondingly, the plurality of adsorption tables 23 in each lifting unit are arranged at intervals along the direction perpendicular to the first direction or along the first direction, and the lifting control of the plurality of adsorption tables 23 can be realized by the plurality of lifting units, and the working efficiency is improved. Preferably, the lifting units are arranged along the first direction, which is more space-saving.

[0084] Exemplarily, the plurality of suction cups 42 on the mechanical arm 41 are arranged in a rectangular shape and are divided into a plurality of suction groups, one suction group for suctioning one battery piece.
