DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application are further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application, and are not used to limit the embodiments of the present application.

[0032] In the description of the embodiments of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise explicitly and specifically limited. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0033] In order to make the description of the present disclosure more detailed and complete, the following describes the embodiments of the embodiments of the present application in an illustrative manner; but this is not the only form of implementation or use of the specific embodiments of the present application. The embodiments include the features of the specific embodiments and the method steps and their order used to construct and operate these specific embodiments. However, other specific embodiments can also be used to achieve the same or equivalent functions and step orders.

[0034] Please refer to Figures 1-6 The lifting device for photovoltaic carrier provided by the embodiments of the present application can solve the problem that the photovoltaic carrier is prone to collapse and deformation during transmission and the height cannot be accurately adjusted in the prior art. Please refer to Figure 1 The structure diagram of the lifting device for photovoltaic carrier provided by the embodiments of the present application, the lifting device for photovoltaic carrier provided by the embodiments of the present application includes a driving member 10, a speed reducer 20, a screw rod 30, a lifting platform 40 and a master controller, and the photovoltaic carrier 50 is lifted by the lifting platform 40.

[0035] As an optional implementation, the application connects the speed reducer 20 with the output shaft 11 of the driving member 10, and sets the lead screw 30 through the speed reducer 20, so as to convert the high-speed rotation of the output shaft 11 into low-speed high-torque output through the driving member 10, thereby driving the lead screw 30 to move in the first direction relative to the speed reducer 20.

[0036] For example, the movement of the lead screw 30 in the first direction relative to the speed reducer 20 can also be understood as the movement of the lead screw 30 in the height direction relative to the speed reducer 20.

[0037] Please refer to Figure 2 The side view of the lifting device of the photovoltaic carrier provided by the embodiment of the application can be observed, and the lifting platform 40 includes at least two lifting supports 41 and a cross rod 45 for connecting the lifting supports 41. The application fixes and connects the middle position of the cross rod 45 with the end of the lead screw 30, so as to drive the cross rod 45 and the lifting supports 41 arranged at the two ends of the cross rod 45 to move in the first direction while the lead screw 30 moves in the first direction relative to the speed reducer 20.

[0038] Further, taking the example of being provided with two lifting supports 41, the application oppositely arranges the two lifting supports 41 at the left and right ends of the cross rod 45, so as to drive the cross rod 45 and the two lifting supports 41 arranged at the two ends of the cross rod 45 to move in the height direction while the lead screw 30 moves in the height direction relative to the speed reducer 20.

[0039] Specifically, the application further sets a master controller connected with the driving member 10. In actual application, a plurality of cell pieces (not shown in the figure) are usually placed on the photovoltaic carrier 50, and the photovoltaic carrier 50 is conveyed from the last process of the production line to the lifting platform 40. Therefore, the height of the lifting platform 40 needs to be adjusted in advance to ensure that the photovoltaic carrier 50 is relatively smoothly conveyed to the lifting platform 40 to perform other cell piece taking and placing operations.

[0040] In the embodiment of the application, the master controller is used to control the driving member 10 to adjust the height of the lifting platform 40, so as to move the lifting platform 40 to the height position close to the photovoltaic carrier 50 in the first direction, to ensure that the photovoltaic carrier 50 is conveyed to the upper side of the lifting platform 40, thereby realizing the lifting action of the photovoltaic carrier 50.

[0041] It needs to be explained that the moving of the lifting platform 40 to the corresponding height position of the photovoltaic carrier 50 can be understood as that the top of the lifting platform 40 is flush with the bottom position of the photovoltaic carrier 50 or slightly lower than the height position of the bottom of the photovoltaic carrier 50, and does not include the height position higher than the bottom of the photovoltaic carrier 50. Only when the top of the lifting platform 40 is flush with the bottom position of the photovoltaic carrier 50 or slightly lower than the height position of the bottom of the photovoltaic carrier 50, can the photovoltaic carrier 50 be smoothly conveyed to the top of the lifting platform, and the position of the cell placed thereon will not be offset during the moving process.

[0042] As an optional embodiment, please refer to Figure 3 As can be observed from the structural schematic view of the lifting support in the lifting device of the photovoltaic carrier provided by the embodiment of the present application, each lifting support 41 comprises a first support rod 42 and a second support rod 43 parallel to the first support rod 42. A plurality of connecting rods 44 are connected and arranged between the first support rod 42 and the second support rod 43. The first support rod 42 and the second support rod 43 are connected and reinforced by the connecting rods 44. The left and right ends of the cross rod 45 are sequentially penetrated through the first support rod 42 of each lifting support 41 and then fixedly connected with the corresponding second support rod 43.

[0043] Of course, the left and right ends of the cross rod 45 can also be fixedly connected with the bottom of the first support rod 42 and the second support rod 43 of each lifting support 41 at the corresponding position. The fixed connection between the cross rod 45 and the lifting support 41 can also be achieved. Bolts can also be arranged at the positions where the cross rod 45 is fixedly connected with the first support rod 42 and the second support rod 43 for further reinforcement. Of course, other rigid connection modes between the cross rod 45 and the lifting support 41 are also feasible, and the present application does not make further limitation in this regard.

[0044] In an optional embodiment, in order to make the size of the lifting platform 40 more suitable for the photovoltaic carrier 50, the connecting rod 44 is arranged in a telescopic structure, so as to adjust the spacing between the first support rod 42 and the second support rod 43 in each lifting support 41.

[0045] Specifically, please refer to Figure 4 As can be observed from the structural schematic view of the connecting rod in the lifting device of the photovoltaic carrier provided by the embodiment of the present application, the connecting rod 44 comprises a first connecting rod 441 and a second connecting rod 442 sleeved on the outer wall of the first connecting rod 441. The adjustment of the telescopic degree between the first connecting rod 441 and the second connecting rod 442 can realize the adjustment of the spacing between the first support rod 42 and the second support rod 43. Of course, the connecting rod 44 can also be arranged in other structures capable of realizing telescopic extension, which should be known by those skilled in the art.

[0046] In the embodiment of the present application, in order to ensure the stability of the lifting platform 40, the number of the connecting rods 44 arranged in each lifting support 41 is at least two, and they are parallel to the cross rod 45. Please continue to refer to Figure 4 , preferably, the corresponding connecting rods 44 are arranged at both ends of the first support rod 42 and the second support rod 43, and the spacing between the plurality of connecting rods 44 is equal, thereby ensuring the balance of the lifting support 41 as a whole, avoiding the shaking phenomenon of the lifting platform 40 when moving in the first direction, and affecting the placement of the battery pieces in the photovoltaic carrier 50.

[0047] Further, since the cross-sectional area of the lead screw 30 is too small, directly fixing and connecting the cross rod 45 with the lead screw 30 will increase the bearing pressure of the lead screw 30, therefore, the present application is provided with a connecting portion 31 at one end of the lead screw 30 close to the lifting platform 40, the cross-sectional area of the connecting portion 31 is greater than that of the lead screw 30, and the cross rod 45 is fixedly arranged on the connecting portion 31, thereby improving the stability of the lifting platform 40 moving in the first direction.

[0048] Of course, the bottom of the cross rod 45 can be directly fixedly arranged on the connecting portion 31, or the cross rod 45 can be arranged by penetrating the connecting portion 31, but it is necessary to ensure that the cross rod 45 and the connecting portion 31 are in a rigid connection relationship, which will not be described in detail herein.

[0049] As an optional embodiment, the distance between the two lifting supports 41 can also be adjusted according to the specific size of the photovoltaic carrier 50, and the cross rod 45 can also be arranged as a telescopic structure.

[0050] Specifically, please refer to Figure 5 , the structure diagram of the cross rod in the lifting device of the photovoltaic carrier provided in the embodiment of the present application, the cross rod 45 includes an inner rod 451 and an outer rod 452 sleeved at both ends of the inner rod 451, the inner rod 451 is fixedly connected with the connecting portion 31, or the inner rod 451 is fixedly arranged by penetrating the connecting portion 31, and the distance between the two lifting supports 41 is adjusted by adjusting the telescopic degree between the two outer rods 452 and the inner rod 451.

[0051] Further, in order to more accurately detect the current height of the lifting platform 40, please continue to refer to Figure 1The first detection member 46 can be specifically set as a distance measuring sensor, and the number of the distance measuring sensor can be adjusted according to actual needs. For example, a distance measuring sensor is arranged at the bottom of the cross rod 45 and the bottom of the two lifting supports 41, and the distance of the cross rod 45 and the two lifting supports 41 relative to the bottom is detected, so as to detect the current height of the lifting platform 40, so that the height of the lifting platform 40 is adjusted by the host controller, and the lifting platform 40 is moved to the height position close to the photovoltaic carrier 50.

[0052] It should be noted that in actual application, the lifting device of the photovoltaic carrier is usually used in cooperation with a production line, so the height position of the photovoltaic carrier 50 in the same production line is relatively fixed, and therefore the second detection member 47 is arranged at the height position corresponding to the photovoltaic carrier 50. The second detection member 47 can be set in the form of a pair of laser sensors, which usually includes a transmitting end 471 for transmitting a laser signal and a receiving end 472 for receiving the laser signal. The transmitting end 471 and the receiving end 472 are arranged at the height position corresponding to the photovoltaic carrier 50 and on opposite sides of the lifting platform 40. When the photovoltaic carrier 50 moves to the height position close to the photovoltaic carrier 50, the laser signal transmitted by the transmitting end 471 is blocked, so that whether the lifting platform 40 moves to the height position corresponding to the photovoltaic carrier 50 is detected by the second detection member 47.

[0053] The current height of the lifting platform 40 is detected in real time by the first detection member 46, and whether the lifting platform 40 moves to the height position close to the photovoltaic carrier 50 is detected by the second detection member 47. The height of the lifting platform 40 is adapted to the height of the photovoltaic carrier 50 by controlling the driving member 10 by the host controller, so that the photovoltaic carrier 50 can be smoothly conveyed above the lifting platform 40.

[0054] Further, in order to avoid the position of the photovoltaic carrier 50 placed on the lifting platform 40 from being offset, affecting subsequent operations of the photovoltaic carrier 50 on the lifting platform 40, a horizontal sensor (not shown in the figure) is arranged at the connection position of the cross rod 45 and the lead screw 30. The horizontal sensor can not only detect the horizontal degree of the cross rod 45 and the lifting supports 41 on both sides of the cross rod 45, but also detect the horizontal degree of the photovoltaic carrier 50 and the lifting platform 40 as a whole after the photovoltaic carrier 50 is placed on the lifting platform 40, so as to avoid the photovoltaic carrier 50 from being offset during the up and down movement and affecting the battery pieces placed therein.

[0055] In an optional embodiment, please refer to Figure 6The function module diagram of the lifting device of the photovoltaic carrier provided in the embodiments of the present application is shown in the figure. The master controller provided in the present application is connected to the driving member 10, the speed reducer 20, the first detection member 46 and the second detection member 47 through wired or wireless mode. The master controller is used to receive the current height of the lifting platform 40 detected by the first detection member 46, and receive the signal of the second detection member 47 to determine whether the lifting platform 40 moves to the height position corresponding to the photovoltaic carrier 50. Then, the master controller controls the driving member 10 to adjust the height of the lifting platform 40 in combination with the detection results of the first detection member 46 and the second detection member 47, so as to cooperate with the robot to take and place the battery piece on the photovoltaic carrier 50 to perform corresponding operation. The specific way of adjusting the height of the lifting platform 40 is not described in detail herein.

[0056] As an optional embodiment, the master controller can be provided in the form of a common controller such as MCU (Microcontroller Unit), PFGA (Field Programmable Gate Array), PLC (Programmable Logic Controller) and the like, which can all achieve the technical effect that the height of the lifting platform 40 is adjusted by the driving member 10 according to the detection results of the first detection member 46 and the second detection member 47. The specific setting form of the master controller is not limited further herein.

[0057] In actual application, the width of the photovoltaic carrier 50 can reach several meters, but the thickness is only 5-8 cm. Therefore, the photovoltaic carrier 50 is prone to collapse during conveying, especially at the middle position. The fixing connection of the cross rod 45 and the lifting support 41 can effectively support the whole photovoltaic carrier 50 during conveying, so as to avoid the collapse of the photovoltaic carrier 50 at the middle position due to the large area of the photovoltaic carrier 50, which causes the position of the battery piece to deviate, and the battery piece is missed or crushed when the robot takes and places the battery piece. In addition, the photovoltaic carrier 50 can be kept uniform in stress during conveying, the deformation of the photovoltaic carrier 50 is reduced, and the service life of the photovoltaic carrier 50 is improved.

[0058] Of course, after the photovoltaic carrier 50 is conveyed to the lifting platform 40, the height of the lifting platform 40 and the photovoltaic carrier 50 can be adjusted by the driving member 10, so as to accurately move the battery piece to the height position close to the robot, facilitate the robot to take and place the battery piece, reduce the missing and damage of the battery piece, and improve the yield and production rhythm of the product. The specific cooperation mode between the photovoltaic carrier 50 and the robot is not described in detail herein.

[0059] As an optional implementation, the cross rod 45, the first supporting rod 42, the second supporting rod 43 and the connecting rod 44 are preferably made of stainless steel structure, which can reduce the material consumption, reduce the weight on the lead screw 30 and simplify the structure, compared with the form of the lifting support 41 directly made of plate structure.

[0060] Of course, the number of the cross rod 45 can also be set to several, and the cross section size of the connecting part 31 should be adjusted accordingly to ensure that several cross rods 45 can be fixed on the connecting part 31, thereby further reinforcing the stability between the lifting supports 41.

[0061] For example, the driving member 10 can be set as a driving motor, and the speed reducer 20 can be set as a common speed reducer 20 such as a gear speed reducer, a turbine speed reducer, a planetary gear speed reducer, etc., as long as the lead screw 30 provided on the speed reducer 20 can be driven by the driving member 10 to move in the first direction, other setting modes are feasible, and the present application does not make further limitation.

[0062] It can be understood that the technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the present application.

[0063] The above implementation is only an exemplary implementation for illustrating the principle of the embodiments of the present application, however, the embodiments of the present application are not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the embodiments of the present application, and these modifications and improvements are also considered as the protection scope of the embodiments of the present application.
