[0039] In addition, if there are these terms "first", "second", these terms are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second" can explicitly or implicitly include at least one of the features. In the description of the application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise explicitly specified and limited, if there are terms such as "mounting", "connecting", "connecting", "fixing" and the like, these terms should be broadly understood. For example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0041] In this application, unless otherwise explicitly specified and limited, if there are similar descriptions such as "first feature on or under second feature", the meaning can be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature "above", "above" and "above" of the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature.

[0042] It is to be noted that when an element is referred to as being "on" or "connected to" another element, it can be directly on the other element or intervening elements can also be present. In addition, the term "connected" can refer to physical or wired connections or it can refer to wireless connections in which signals are exchanged between devices. As used herein, the terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms are used for description only and are not meant to be limiting.

[0043] In the process of laminating the photovoltaic module, one of the front glass sheet 500 and the back glass sheet 600 is placed on the other, the alignment operation is performed, the front glass sheet 500 and the back glass sheet 600 are aligned in the vertical direction, and then the laminating operation is performed. In the alignment process, the alignment wheel needs to push the side edges of the front glass sheet 500 and the back glass sheet 600. In general, the alignment wheel is in contact with the front glass sheet 500 and the back glass sheet 600 at the same time. When the size and shape of the front glass sheet 500 or the back glass sheet 600 deviates, and the size of the front glass sheet 500 or the back glass sheet 600 in the alignment direction is greater than the preset size, the pushing pressure of the alignment wheel on the front glass sheet 500 or the back glass sheet 600 will be too large, which will cause the front glass sheet 500 or the back glass sheet 600 to be damaged. The photovoltaic module laminating alignment device 100 provided in the embodiment of the present application can be used for the alignment operation of the front glass sheet 500 and the back glass sheet 600 in the process of laminating the photovoltaic module, and can avoid the pushing pressure on the front glass sheet 500 or the back glass sheet 600 being too large, which will cause the front glass sheet 500 or the back glass sheet 600 to be damaged.

[0044] In combination Figure 1 and Figure 2 The photovoltaic module laminating alignment device 100 provided in the embodiment of the present application includes a supporting mechanism 110, a first eccentric wheel 120, a second eccentric wheel 130, and an adjusting mechanism 140.

[0045] The supporting mechanism 110 includes a supporting shaft 111, which is vertically arranged and used for mounting the first eccentric wheel 120 and the second eccentric wheel 130. The first eccentric wheel 120 and the second eccentric wheel 130 are arranged along the axial direction of the supporting shaft 111 and are respectively rotatably connected to the supporting shaft 111. The rotation axes of the first eccentric wheel 120 and the second eccentric wheel 130 are in the vertical direction. The first eccentric wheel 120 and the second eccentric wheel 130 are used as alignment wheels and are used for being in contact with the front glass sheet 500 and the back glass sheet 600 respectively in the process of laminating alignment.

[0046] For the convenience of description, it is assumed that the front glass sheet 500 is located on the lower conveying device 700 in the glass combining process, the back glass sheet 600 is carried to the upper side of the front glass sheet 500 by the carrying device 800 in the form of a suction cup or the like, and the first eccentric wheel 120 is located below the second eccentric wheel 130, the first eccentric wheel 120 is used to contact the side edge of the front glass sheet 500, and the second eccentric wheel 130 is used to contact the back glass sheet 600.

[0047] The adjusting mechanism 140 is connected to the first eccentric wheel 120 and the second eccentric wheel 130, and is used to adjust the rotation angle of the first eccentric wheel 120 and the second eccentric wheel 130. When the rotation angle of the first eccentric wheel 120 and the second eccentric wheel 130 is adjusted by the adjusting mechanism 140, the contact positions of the wheel surface of the first eccentric wheel 120 and the wheel surface of the second eccentric wheel 130 with the front glass sheet 500 and the back glass sheet 600 can be adjusted respectively, so that the distance between the contact positions of the first eccentric wheel 120 and the second eccentric wheel 130 with the front glass sheet 500 and the back glass sheet 600 and the support shaft 111 is adjusted, and different sizes of the front glass sheet 500 and the back glass sheet 600 are adapted.

[0048] In the embodiment, the photovoltaic module glass combining and aligning device 100 can be arranged on both sides of the front glass sheet 500 and the back glass sheet 600 respectively, so that the photovoltaic module glass combining and aligning devices 100 on both sides are close to each other to realize alignment. Alternatively, the photovoltaic module glass combining and aligning device 100 can be arranged on one side of the front glass sheet 500 and the back glass sheet 600, and a common aligning wheel can be arranged on the other side, so that the photovoltaic module glass combining and aligning device 100 and the common aligning wheel are close to each other to realize alignment.

[0049] Due to the photovoltaic module glass combining and aligning device 100, the rotation angle of the first eccentric wheel 120 and the second eccentric wheel 130 can be adjusted according to the shape and size of the front glass sheet 500 and the back glass sheet 600 respectively, so that the front glass sheet 500 or the back glass sheet 600 is not excessively pressed during the alignment process, and the front glass sheet 500 or the back glass sheet 600 is not damaged, thereby effectively improving the yield, and further improving the production efficiency and production quality.

[0050] According to one embodiment of the present application, the adjusting mechanism 140 includes a locking member 141 corresponding to the first eccentric wheel 120 and the second eccentric wheel 130 respectively, and the locking member 141 is configured to be switched between a locked state and an unlocked state. In the locked state, the locking member 141 is connected to the corresponding first eccentric wheel 120 or second eccentric wheel 130 to lock the rotation angle of the first eccentric wheel 120 or second eccentric wheel 130. In the unlocked state, the locking member 141 is separated from the corresponding first eccentric wheel 120 or second eccentric wheel 130 to allow the first eccentric wheel 120 or second eccentric wheel 130 to rotate.

[0051] The switching of the locking member 141 between the locked state and the unlocked state can be achieved by manual operation or by electric driving, etc. Taking the locking member 141 corresponding to the first eccentric wheel 120 as an example, an operator can make the locking member 141 enter the locked state by a specific action, at this time, the locking member 141 is tightly connected with the first eccentric wheel 120, limiting the rotation of the first eccentric wheel 120 around the support shaft 111, thereby fixing the current rotation angle of the first eccentric wheel 120; when it is needed to adjust the rotation angle of the first eccentric wheel 120, the operator makes the locking member 141 disengage from the first eccentric wheel 120 by a reverse action, entering the unlocked state, at this time, the first eccentric wheel 120 can freely rotate around the support shaft 111, and after rotating the first eccentric wheel 120 to the required angle, the locking member 141 is used to make it return to the locked state, completing the adjustment of the rotation angle of the first eccentric wheel 120. The operation mode of the locking member 141 corresponding to the second eccentric wheel 130 can be the same as or similar to that of the locking member 141 corresponding to the first eccentric wheel 120, which will not be described herein.

[0052] After the adjustment is completed, the locking member 141 can stably fix the angle of the corresponding first eccentric wheel 120 or second eccentric wheel 130, avoiding the angle deviation of the first eccentric wheel 120 or second eccentric wheel 130 due to external force during the regulation process, ensuring the stability and accuracy of the regulation operation, and thereby reducing the damage of the front glass sheet 500 or back glass sheet 600 caused by the unstable angle of the first eccentric wheel 120 or second eccentric wheel 130.

[0053] According to an embodiment of the present application, the locking member 141 comprises a locking bolt, which is threadedly connected with the support mechanism 110; or the locking member 141 comprises an extension member, which is fixedly connected with the support mechanism 110.

[0054] As an optional mode, when the locking member 141 is a locking bolt and is threadedly connected with the support mechanism 110, the support 112 of the support mechanism 110 is provided with a threaded hole matched with the locking bolt, and the position of the threaded hole needs to be ensured to be able to contact with the corresponding first eccentric wheel 120 or second eccentric wheel 130 after the locking bolt is screwed in. Taking the locking bolt corresponding to the first eccentric wheel 120 as an example, when it is needed to lock the rotation angle of the first eccentric wheel 120, an operator rotates the locking bolt in one direction, due to the thread cooperation, the locking bolt will move axially along the threaded hole and gradually approach the first eccentric wheel 120, until the end of the locking bolt abuts against the first eccentric wheel 120, thereby limiting the rotation of the first eccentric wheel 120 through the friction force; when it is needed to unlock, the operator rotates the locking bolt in the other direction, the locking bolt moves reversely axially along the threaded hole, gradually disengaging from the contact with the first eccentric wheel 120, thereby removing the limitation on the first eccentric wheel 120, so that the first eccentric wheel 120 can freely rotate. The locking bolt corresponding to the second eccentric wheel 130 is the same, which will not be described herein.

[0055] When the locking bolt is used as the locking member 141, the threaded connection has good self-locking property. Once the locking bolt is tightened against the corresponding first eccentric wheel 120 or second eccentric wheel 130, the locking bolt will not loosen by itself without external force, and can stably lock the corresponding first eccentric wheel 120 or second eccentric wheel 130 for a long time. Moreover, the locking bolt has a simple structure, is easy to obtain and replace, and has low maintenance cost.

[0056] As another optional mode, if the locking member 141 is a telescopic member and is fixedly connected with the support mechanism 110, the telescopic member can adopt a structure such as a pneumatic telescopic cylinder, a hydraulic telescopic cylinder or an electric telescopic cylinder. The fixed end of the telescopic member is connected with the bracket 112 or the like of the support mechanism 110, and the telescopic end is directed towards the corresponding first eccentric wheel 120 or second eccentric wheel 130. When locking is needed, the telescopic end of the telescopic member is extended and contacts and presses against the eccentric wheel, so as to achieve locking. When unlocking is needed, the telescopic end is retracted and is separated from the contact with the eccentric wheel.

[0057] When the telescopic member is used as the locking member 141, the automatic locking and unlocking can be achieved by controlling the telescopic action of the telescopic member, without manual operation, so as to improve the operation efficiency. The telescopic member is particularly suitable for large-scale automatic glass-bonding production lines, can match the automatic control rhythm of the production line, reduces manual intervention, reduces manual operation errors, and further improves the automatic level and production efficiency of glass-bonding production.

[0058] In some embodiments, when the adjustment mechanism 140 achieves the angle locking of the first eccentric wheel 120 or second eccentric wheel 130 through the locking member 141, the connection mode of the locking member 141 and the first eccentric wheel 120 or second eccentric wheel 130 is face contact and pressing. Taking the locking member 141 corresponding to the first eccentric wheel 120 as an example, the end of the locking member 141 is provided with a flat pressing surface. When the locking member 141 is in the locking state, the pressing surface is attached to the upper end surface or lower end of the first eccentric wheel 120, the contact area is increased to disperse the pressing force, and the local pressure is prevented from being too large to cause damage to the wheel surface of the first eccentric wheel 120. In the unlocking state, the pressing surface of the locking member 141 is completely separated from the first eccentric wheel 120, and does not contact the first eccentric wheel 120, so that the first eccentric wheel 120 is not affected by the frictional resistance of the locking member 141 in the rotation process, and can rotate smoothly. The connection mode of the locking member 141 and the first eccentric wheel 120 or second eccentric wheel 130 in face contact and pressing can effectively disperse the force in the locking state, avoid local stress concentration to cause wear or deformation of the eccentric wheel, and prolong the service life of the eccentric wheel. In the unlocking state, the locking member 141 is completely separated from the first eccentric wheel 120 or second eccentric wheel 130, the frictional resistance between them is eliminated, the rotation of the eccentric wheel is smoother, the energy loss in the rotation process is reduced, and damage to the eccentric wheel caused by friction is avoided.

[0059] It can be understood that the contact position of the locking member 141 with the first eccentric wheel 120 or the second eccentric wheel 130 can also be the wheel surface of the first eccentric wheel 120 or the second eccentric wheel 130, for example Figure 1 as shown in the middle.

[0060] In some embodiments, a spacing sleeve is arranged between the first eccentric wheel 120 and the second eccentric wheel 130, the spacing sleeve is sleeved on the support shaft 111, and the length of the spacing sleeve is determined according to the required axial spacing of the first eccentric wheel 120 and the second eccentric wheel 130, which is used to limit the relative movement of the two eccentric wheels in the axial direction, and ensure that the two eccentric wheels maintain a fixed spacing in the axial direction along the support shaft 111, avoiding affecting the contact position with the glass sheet due to axial offset.

[0061] According to an embodiment of the present application, the adjusting mechanism 140 includes rotary drive structures 142 corresponding to the first eccentric wheel 120 and the second eccentric wheel 130, respectively, the rotary drive structures 142 are mounted to the support mechanism 110 and are in transmission connection with the corresponding first eccentric wheel 120 or second eccentric wheel 130, and the rotary drive structures 142 are used to drive the corresponding first eccentric wheel 120 or second eccentric wheel 130 to rotate.

[0062] Taking the rotary drive structure 142 corresponding to the first eccentric wheel 120 as an example, the power output part of the rotary drive structure 142 is in transmission connection with the first eccentric wheel 120, when the rotary drive structure 142 is started, the power output by the rotary drive structure 142 will be transmitted to the first eccentric wheel 120, driving the first eccentric wheel 120 to rotate around the support shaft 111; similarly, when the rotary drive structure 142 corresponding to the second eccentric wheel 130 is started, it will independently drive the second eccentric wheel 130 to rotate around the support shaft 111. By controlling the start and stop of different rotary drive structures 142, and controlling the running direction and running time of the rotary drive structures 142, the rotation angles of the first eccentric wheel 120 and the second eccentric wheel 130 can be adjusted respectively, and the independent control of the rotation angles of the two eccentric wheels can be realized.

[0063] The arrangement of the rotary drive structure 142 realizes the mechanical adjustment of the rotation angle of the eccentric wheel, which can more accurately control the rotation angle of the eccentric wheel, avoid the angle deviation caused by the operation force, judgment error and other factors during manual adjustment, and improve the accuracy of the adjustment of the rotation angle of the eccentric wheel. At the same time, the mechanical driving mode can be connected with the control device 1000 later, realizing automatic control, laying a foundation for the overall automatic control of the glass combining equipment, reducing the operation steps of the operator, reducing the labor intensity of the operator, and ensuring the consistency of the adjustment angle each time, making the glass combining operation of different batches have a unified standard, improving the stability of product quality, and reducing the problem of glass sheet breakage caused by inconsistent angle adjustment.

[0064] According to one embodiment of the present application, the rotary driving structure 142 comprises: a rotary motor 1421 fixed to the support mechanism 110; a transmission assembly 1422 connected with the motor shaft of the rotary motor 1421 and connected with the first eccentric wheel 120 or the second eccentric wheel 130.

[0065] The rotary motor 1421 is fixedly installed at a preset position of the support mechanism 110, for example, is fixedly installed at the support 112 of the support mechanism 110, and the axis direction of the motor shaft is parallel to the rotation axis direction of the first eccentric wheel 120 or the second eccentric wheel 130, that is, is parallel to the axis direction of the support shaft 111, so as to ensure that the transmission assembly 1422 can smoothly realize power transmission. The transmission assembly 1422 is respectively connected with the motor shaft of the rotary motor 1421 and the corresponding first eccentric wheel 120 or second eccentric wheel 130. When the rotary motor 1421 is started, the motor shaft starts to rotate, and the rotary motion is transmitted to the first eccentric wheel 120 or the second eccentric wheel 130 through the transmission assembly 1422, so as to drive the first eccentric wheel 120 or the second eccentric wheel 130 to rotate around the support shaft 111. When the rotation angle of the first eccentric wheel 120 or the second eccentric wheel 130 is adjusted, the rotation direction of the eccentric wheel can be changed by controlling the rotation direction of the rotary motor 1421, and the rotation angle of the eccentric wheel can be controlled by controlling the running time of the rotary motor 1421. For example, if it is required to make the first eccentric wheel 120 or the second eccentric wheel 130 rotate clockwise by a certain angle, the rotary motor 1421 can be controlled to run clockwise for a corresponding time; if it is required to make the first eccentric wheel 120 or the second eccentric wheel 130 rotate counterclockwise, the motor can be controlled to run counterclockwise for a corresponding time, so as to realize accurate control of the rotation angle of the eccentric wheel.

[0066] The rotary motor 1421 as a power source has the characteristics of stable power and controllable rotation speed, can provide continuous and stable power for the rotation of the eccentric wheel, and avoids unstable rotation of the eccentric wheel due to insufficient power or power fluctuation. The setting of the transmission assembly 1422 can effectively transmit the power of the motor, ensure that the rotary motion of the motor is accurately converted into the rotary motion of the eccentric wheel, reduce the loss in the power transmission process, and improve the power transmission efficiency. The rotation direction and running time of the motor are controlled to adjust the angle of the eccentric wheel, which is simple to operate and has high control precision, can realize fine adjustment of the angle of the eccentric wheel, better adapt the front glass sheet 500 and the back glass sheet 600 of different sizes and shapes, further reduce the risk of glass sheet damage caused by improper angle adjustment, and at the same time provide a convenient condition for subsequent automatic control with the control device 1000, which is beneficial to improve the overall automation level and production efficiency of the glass combining equipment.

[0067] According to one embodiment of the present application, the transmission assembly 1422 comprises a gear set, a synchronous belt transmission assembly or a chain transmission assembly.

[0068] When the transmission assembly 1422 is a gear set, the gear set includes at least two gears meshing with each other, one of which is fixedly connected with the motor shaft of the rotating motor 1421 as a driving gear, and the other is fixedly connected with the corresponding first eccentric wheel 120 or second eccentric wheel 130 as a driven gear. The driving gear and the driven gear achieve power transmission through direct meshing or by adding an intermediate gear. When the motor shaft rotates, the driving gear rotates, driving the driven gear to rotate through gear meshing, and in turn driving the corresponding first eccentric wheel 120 or second eccentric wheel 130 to rotate. The gear set transmission has the advantages of accurate transmission ratio, high transmission efficiency, and compact structure, and can ensure that the rotation angle of the motor is accurately transmitted to the corresponding first eccentric wheel 120 or second eccentric wheel 130, making the angle adjustment of the corresponding first eccentric wheel 120 or second eccentric wheel 130 more accurate, and is suitable for scenarios where the accuracy of angle adjustment is relatively high.

[0069] When the transmission assembly 1422 is a synchronous belt transmission assembly, it includes a synchronous belt, a driving synchronous pulley, and a driven synchronous pulley. The driving synchronous pulley is fixedly connected with the motor shaft, and the driven synchronous pulley is fixedly connected with the first eccentric wheel 120 or second eccentric wheel 130. The synchronous belt is sleeved on the driving synchronous pulley and the driven synchronous pulley. The motor shaft rotates to drive the driving synchronous pulley to rotate, which in turn drives the driven synchronous pulley to rotate through the transmission of the synchronous belt, thereby rotating the first eccentric wheel 120 or second eccentric wheel 130. The synchronous belt transmission assembly has low noise and small vibration during operation, can reduce noise pollution generated during transmission, improve the production environment, and has a certain elasticity, which can play a buffering role during transmission to avoid damage to the motor or eccentric wheel caused by sudden power impact, prolonging the service life of the equipment.

[0070] When the transmission assembly 1422 is a chain transmission assembly, it includes a chain, a driving sprocket, and a driven sprocket. The driving sprocket is fixedly connected with the motor shaft, and the driven sprocket is fixedly connected with the eccentric wheel. The chain is sleeved on the driving sprocket and the driven sprocket. The motor shaft drives the driving sprocket to rotate, which in turn drives the driven sprocket to rotate through the chain, thereby rotating the first eccentric wheel 120 or second eccentric wheel 130. The chain transmission assembly has the characteristics of strong carrying capacity and wear resistance, and can work stably in a relatively harsh production environment and is not easily affected by dust, oil stains, and other factors. It is suitable for long-term continuous operation of the glass combining production line, ensures the stability and reliability of power transmission, and in turn ensures the continuous and stable operation of the glass combining and aligning operation.

[0071] Of course, the transmission assembly 1422 can also adopt other structural forms, which are within the scope of the present embodiment.

[0072] In combination with Figure 2 and Figure 3The present application also provides a glass bonding device, which comprises a conveying device 700, a carrying device 800, a plurality of aligning devices and a plurality of moving devices 900. The conveying device 700 has a glass bonding station 710, which is a position on the conveying path of the conveying device 700 for glass bonding operation, and the conveying device 700 is used to convey the front glass sheet 500 of the photovoltaic module to the glass bonding station 710. The carrying device 800 is used to carry the back glass sheet 600 of the photovoltaic module to the glass bonding station 710. The plurality of aligning devices are arranged on both sides of the conveying device 700, wherein at least one aligning device on one side of the conveying device 700 adopts the photovoltaic module glass bonding aligning device 100 of the above embodiment. The plurality of moving devices 900 are connected to the plurality of aligning devices correspondingly, and the moving device 900 is used to drive the corresponding aligning device to move to the glass bonding station 710 or drive the corresponding aligning device to move away from the glass bonding station 710.

[0073] Exemplarily, the conveying device 700 can adopt a conveying belt structure, the conveying belt runs in a preset conveying direction, the glass bonding station 710 is arranged at the middle or other position of the conveying belt, and a positioning structure can be arranged on the conveying belt to ensure that the front glass sheet 500 does not deviate during conveying. When the front glass sheet 500 is conveyed to the glass bonding station 710, the conveying device 700 stops running and waits for subsequent operation. The conveying device 700 adopts the conveying belt structure, which can realize continuous conveying of the front glass sheet 500, improve the conveying efficiency of the front glass sheet 500, and the positioning structure can ensure the position accuracy of the front glass sheet 500 during conveying, thereby avoiding subsequent glass bonding alignment difficulty caused by conveying deviation.

[0074] Exemplarily, the carrying device 800 comprises a mechanical arm and a suction cup arranged on the active end of the mechanical arm. When the back glass sheet 600 needs to be carried, the mechanical arm drives the suction cup to move to the storage position of the back glass sheet 600, the suction cup adsorbs the back glass sheet 600, and then the mechanical arm drives the back glass sheet 600 to move to the position directly above the glass bonding station 710, so that the back glass sheet 600 is roughly aligned with the front glass sheet 500 below in the vertical position. The carrying device 800 adopts the suction cup to stably adsorb and carry the back glass sheet 600, thereby avoiding falling or damage of the back glass sheet 600 during carrying, and the flexible movement of the mechanical arm can ensure that the back glass sheet 600 is accurately moved to the position above the glass bonding station 710, thereby laying a good foundation for subsequent alignment and glass bonding operation.

[0075] Exemplarily, the plurality of aligning devices are arranged on both sides of the conveying device 700, for example, two aligning devices are arranged on the left side and the right side of the conveying device 700 respectively, and at least one aligning device on one side adopts the photovoltaic module glass bonding aligning device 100.

[0076] Exemplarily, the moving device 900 can adopt a linear guide rail slider structure or a screw nut structure, etc. The fixed part of the moving device 900 is connected with the ground or the equipment rack, and the movable part is connected with the aligning device. When the aligning needs to be performed, the moving device 900 drives the aligning device to move to the glass combining station 710 until the aligning device contacts the side edges of the front glass sheet 500 and the back glass sheet 600. When the aligning is completed, the moving device 900 drives the aligning device to move away from the glass combining station 710 so as to perform subsequent operations. When the moving device 900 adopts the linear guide rail slider or the screw nut structure, the stable movement of the aligning device can be realized, the stability of the aligning device in the movement process is ensured, the stability of the aligning device when contacting the glass sheet is ensured, the glass sheet breakage caused by the unstable movement of the aligning device is reduced, and meanwhile, the accurate driving of the moving device 900 can control the movement distance of the aligning device, so that the aligning device can accurately contact the side edges of the glass sheet, and the aligning precision is improved.

[0077] In combination Figure 4 According to one embodiment of the present application, the glass combining equipment further comprises a control device 1000, the control device 1000 is signal connected with the conveying device 700, the carrying device 800 and the moving device 900, and the control device 1000 is used for controlling the operation of the conveying device 700, the carrying device 800 and the moving device 900.

[0078] The control device 1000 can adopt a PLC controller or an industrial computer, etc. and is signal connected with the conveying device 700, the carrying device 800 and the moving device 900 through a wire or a wireless communication module.

[0079] Exemplarily, the control device 1000 pre-stores a control program. When the lamination operation needs to be started, the control device 1000 first sends a control signal to the conveying device 700 to control the conveying device 700 to start running and convey the front glass sheet 500 to the lamination station 710. When the position sensor on the conveying device 700 detects that the front glass sheet 500 reaches the lamination station 710, a feedback signal is sent to the control device 1000. After the control device 1000 receives the feedback signal, a stop signal is sent to the conveying device 700 to control the conveying device 700 to stop running. At the same time, the control device 1000 sends a control signal to the carrying device 800 to control the carrying device 800 to perform actions such as adsorption and movement, and carry the back glass sheet 600 to above the lamination station 710. When the position sensor on the carrying device 800 detects that the back glass sheet 600 reaches the specified position, a feedback signal is sent to the control device 1000. Then, the control device 1000 sends a control signal to the moving device 900 to control the moving device 900 to drive the alignment device to move to the lamination station 710 to perform the alignment operation. After the alignment is completed, the moving device 900 sends a feedback signal to the control device 1000. The control device 1000 then sends a signal to the carrying device 800 to control the carrying device 800 to release the back glass sheet 600, and the lamination operation is completed.

[0080] The arrangement of the control device 1000 realizes the cooperative work of the components of the lamination equipment. Through the pre-set control program, the running sequence and the running state of the conveying device 700, the carrying device 800 and the moving device 900 can be accurately controlled, the production confusion caused by the asynchronous operation between the devices is avoided, and the overall running efficiency of the lamination equipment is improved. At the same time, the control device 1000 can receive the feedback signals of the devices and monitor the running state of the devices in real time. When a device fails or abnormally operates, the control device 1000 can timely discover and send an alarm signal, so that the operator can timely perform maintenance and processing, and the influence of the equipment failure on the production progress is reduced. In addition, the programmability of the control device 1000 enables the lamination equipment to adapt to the lamination needs of photovoltaic modules of different specifications. Only by modifying the related parameters in the control program, the running parameters of the devices can be adjusted, and the versatility and flexibility of the equipment are improved.

[0081] According to one embodiment of the present application, the lamination equipment further comprises an image acquisition device 1100, the image acquisition device 1100 is used to acquire image information of the front glass sheet 500 and the back glass sheet 600; the control device 1000 is further in signal connection with the image acquisition device 1100 and the adjustment mechanism 140 of the photovoltaic module lamination alignment device 100, and the control device 1000 is used to generate adjustment parameters based on the image information, and the adjustment mechanism 140 performs actions according to the adjustment parameters.

[0082] Exemplarily, the adjustment parameter includes a target rotation angle of the first eccentric wheel 120 and the second eccentric wheel 130. The image acquisition device 1100 can adopt an industrial camera, and a lens of the industrial camera is directed toward the back glass sheet 600 on the assembly station 710 or the conveying device 800, so that clear images of the front glass sheet 500 and the back glass sheet 600 can be captured. The image acquisition device 1100 is connected to the control device 1000 through a data transmission line or a wireless module, and transmits the captured image information of the front glass sheet 500 and the back glass sheet 600 to the control device 1000. The control device 1000 is installed with image recognition software, which can process and analyze the received image information, for example, recognize the edge profile of the front glass sheet 500 and the back glass sheet 600, determine the size of the front glass sheet 500 and the back glass sheet 600, and thus determine the target rotation angle of the first eccentric wheel 120 and the second eccentric wheel 130. The control device 1000 is connected to the adjustment mechanism 140 of the photovoltaic module assembly device 100 in a wired or wireless manner, sends a control signal to the adjustment mechanism 140, and controls the adjustment mechanism 140 to adjust the first eccentric wheel 120 and the second eccentric wheel 130 according to the target rotation angle, so as to adapt to the size of the current glass sheet.

[0083] The image acquisition device 1100 can acquire the image information of the front glass sheet 500 and the back glass sheet 600 in real time, and provide accurate judgment basis for the control device 1000, so as to avoid the error caused by the naked eye observation of the operator, improve the accuracy of the judgment of the glass sheet state, and improve the accuracy of the judgment of the glass sheet state. The control device 1000 can quickly and accurately analyze the size and position deviation of the glass sheet by processing the image information through the image recognition software, and then timely sends an adjustment signal to the adjustment mechanism 140, so as to realize the real-time adjustment of the eccentric wheel angle, make the assembly device always adapt to the current glass sheet state, and reduce the improper assembly and glass sheet damage caused by the size change of the glass sheet. The automatic adjustment mode based on the image information further improves the automation level and intelligent degree of the assembly device, reduces the manual intervention, and improves the production efficiency and the stability of the product quality.

[0084] According to one embodiment of the present application, the image acquisition device includes a first image acquisition device and a second image acquisition device. The first image acquisition device is located on one side of the assembly station 710 and is signal-connected to the control device 1000, and the first image acquisition device is used to acquire first image information of the front glass sheet 500 on the assembly station 710. The second image acquisition device is arranged on the conveying device 800 and is signal-connected to the control device 1000, and the second image acquisition device is used to acquire second image information of the back glass sheet 600 conveyed by the conveying device 800.

[0085] Exemplarily, the first image acquisition device and the second image acquisition device can adopt an industrial camera or the like. The first image acquisition device is installed on one side of the fusing station 710, for example, on the left side support 112 of the conveying device 700, with its lens facing the fusing station 710, so as to ensure that the first image acquisition device can capture a complete image of the front glass sheet 500, including the two side edge profiles of the front glass sheet 500, when the front glass sheet 500 is conveyed to the fusing station 710. The first image acquisition device is connected to the control device 1000 through wired or wireless signals, and transmits the captured first image information to the control device 1000 in real time. The second image acquisition device is installed on the movable end of the handling device 800, and moves with the movable end of the handling device 800, with its lens facing the back glass sheet 600 adsorbed by the handling device 800. When the handling device 800 adsorbs the back glass sheet 600 and moves, the second image acquisition device can capture an image of the back glass sheet 600, obtain second image information such as the two side edge profiles of the back glass sheet 600, and transmit the second image information to the control device 1000. The control device 1000 processes the first image information and the second image information respectively, and determines the sizes of the front glass sheet 500 and the back glass sheet 600 respectively.

[0086] The first image acquisition device is fixed on one side of the fusing station 710, and can stably capture an image of the front glass sheet 500, without being affected by the movement of other devices, so as to ensure that the obtained first image information is stable and clear, and provide a reliable basis for the control device 1000 to accurately determine the size and position of the front glass sheet 500. The second image acquisition device moves with the handling device 800, and can obtain image information of the back glass sheet 600 whether the handling device 800 is in the adsorption position or in the movement process, so as to avoid the situation that the image acquisition is not timely or complete due to the movement of the back glass sheet 600, and ensure that the control device 1000 can master the state of the back glass sheet 600 in real time. By respectively arranging the first image acquisition device and the second image acquisition device, image information of the front glass sheet 500 and the back glass sheet 600 can be obtained respectively, so that the control device 1000 can analyze the sizes of the two glass sheets respectively, and then adjust the angles of the corresponding eccentric wheels, so as to better realize the accurate correction of the front glass sheet 500 and the back glass sheet 600, further reduce the risk of glass sheet breakage, and improve the fusing quality.

[0087] Alternatively, the control device 1000 determines the sizes of the front glass sheet 500 and the back glass sheet 600 through the image information collected by the first image acquisition device and the second image acquisition device, and the specific operation is as follows:

[0088] The capturing ranges of the first image capturing device and the second image capturing device are determined. The first image capturing device is fixedly installed on the side support 112 of the annealing station 710, and the lens thereof faces the bearing area of the annealing station 710, so as to ensure that the whole area of the front glass sheet 500 on the conveying device 700 can be completely captured, including the four side edges and the central area of the front glass sheet 500. The second image capturing device is installed at the end of the mechanical arm of the handling device 800, and moves synchronously with the mechanical arm. The lens thereof faces the back glass sheet 600 adsorbed by the mechanical arm chuck, so as to completely capture the four side edges and the central area of the back glass sheet 600, and the capturing angle is always perpendicular to the surface of the back glass sheet 600, so as to avoid image distortion caused by angle inclination.

[0089] When the front glass sheet 500 is conveyed to the annealing station 710 and stops, the first image capturing device is started to capture multiple images of the front glass sheet 500 (to avoid errors caused by light interference in single capturing), and the captured multiple sets of image information of the front glass sheet 500 are sent to the control device 1000. After receiving the image information, the control device 1000 starts the built-in image preprocessing module to first perform noise reduction processing on the image to remove stray points caused by environmental light changes, dust, etc., and then perform edge enhancement processing to make the side edge profile of the front glass sheet 500 clearer. Subsequently, the image recognition module of the control device 1000 performs edge detection on the preprocessed image to automatically identify the coordinate positions of the four side edges of the front glass sheet 500 in the image coordinate system, for example, to identify the starting coordinate and the ending coordinate of the left side edge, the starting coordinate and the ending coordinate of the right side edge, the starting coordinate and the ending coordinate of the front side edge, and the starting coordinate and the ending coordinate of the rear side edge of the front glass sheet 500.

[0090] The control device 1000 has pre-stored therein a conversion ratio of the image pixels of the first image capturing device to the actual size, which is determined through early calibration, i.e., the number of pixels corresponding to a standard part with a known actual length in the image is known, so as to obtain the actual length represented by each pixel. According to the conversion ratio, the control device 1000 calculates the actual size of the front glass sheet 500, for example, by multiplying the horizontal distance (pixel number) of the left side edge and the right side edge in the image coordinate system by the conversion ratio to obtain the actual width of the front glass sheet 500, and by multiplying the vertical distance (pixel number) of the front side edge and the rear side edge in the image coordinate system by the conversion ratio to obtain the actual length of the front glass sheet 500.

[0091] During the process of the mechanical arm of the conveying device 800 sucking the back glass 600 and moving to hover above the glassing station 710 or after the action is completed, the second image acquisition device continuously takes multiple images of the back glass 600 and sends multiple sets of back glass 600 image information to the control device 1000. The control device 1000 uses the same process as processing the front glass 500 image to first pre-process the back glass 600 image by denoising and edge enhancement, and then detects the image coordinates of the four sides of the back glass 600 through the image recognition module, and calculates the actual width and length of the back glass 600 by combining the image pixel and actual size conversion ratio of the second image acquisition device.

[0092] By using the first image acquisition device and the second image acquisition device to respectively acquire the image information of the front glass 500 and the back glass 600, the independent detection of the sizes of the two kinds of glasses can be realized, the detection blind area caused by the angle limitation of a single acquisition device is avoided, and it is ensured that the detection range fully covers the key area of the glass. The control device 1000 pre-processes and edge detects the image, effectively eliminates the influence of environmental interference factors on the image quality, makes the side edge contour recognition more accurate, and reduces the size calculation error caused by image blur.

[0093] Based on the preset image pixel and actual size conversion ratio, the control device 1000 can quickly convert the image coordinates into actual sizes. Compared with manual measurement, the detection efficiency is greatly improved, and the contact type operation on the glass during manual measurement is avoided, so that the glass surface is prevented from being scratched or deviated due to manual contact.

[0094] Optionally, if the control device 1000 calculates that the actual size of the front glass 500 is within the preset qualified range, and the actual size of the back glass 600 is within the preset qualified range, it is determined that the sizes of the front glass 500 and the back glass 600 meet the requirements of the regulation; if the size of any glass exceeds the qualified range, the control device 1000 will send an adjustment instruction to the corresponding adjustment mechanism 140 to adjust the rotation angle of the first eccentric wheel 120 or the second eccentric wheel 130, so as to meet the regulation requirements.

[0095] The detection process is completely completed automatically by the control device 1000 without manual intervention, which meets the automation production needs of the glassing equipment, improves the coherence and stability of the overall production process, and further guarantees the yield of the glassing product.

[0096] In combination Figure 5 , the application also provides a control method of the glassing equipment of the above-mentioned embodiments. The execution subject of the control method can be a control device, and the control method comprises the following steps.

[0097] S100, control the conveying device 700 to convey the front glass 500 of the photovoltaic module to the glassing station 710.

[0098] Exemplarily, before the conveying device 700 starts, it is ensured that the front glass sheet 500 is stably placed on the bearing surface of the conveying device 700, so as to avoid the inclination or deviation of the glass sheet before conveying. The control device 1000 sends a start signal to the conveying device 700, and the conveying device 700 runs along the fixed path at the preset conveying speed, driving the front glass sheet 500 to move to the glass combining station 710. The first image acquisition device and other elements capable of realizing position detection arranged on the conveying device 700 monitor the position of the front glass sheet 500 in real time. When the element detects that the edge of the front glass sheet 500 is aligned with the preset positioning mark of the glass combining station 710, it immediately sends a position-in-place signal to the control device 1000. After receiving the signal, the control device 1000 sends a stop signal to the conveying device 700, and the conveying device 700 stops running, so that the front glass sheet 500 is accurately stopped at the specified position of the glass combining station 710. At this time, the center of the front glass sheet 500 is approximately coincident with the center of the glass combining station 710, which prepares for subsequent operations.

[0099] Through the cooperative work of the control device 1000, the conveying device 700 and the position detection element, the accurate conveying and positioning of the front glass sheet 500 are realized, the position error caused by manual placement of the glass sheet is avoided, and it is ensured that the front glass sheet 500 can be stopped at the unified position of the glass combining station 710 each time, so as to provide a stable reference for the subsequent carrying and glass combining of the back glass sheet 600, and reduce the subsequent operation errors caused by the position deviation of the front glass sheet 500.

[0100] S200, control the carrying device 800 to carry the back glass sheet 600 of the photovoltaic module to the glass combining station 710.

[0101] Exemplarily, the control device 1000 sends a carrying instruction to the carrying device 800. The movable end of the mechanical arm of the carrying device 800 first moves to the storage rack of the back glass sheet 600 according to the preset trajectory. When the suction cup of the movable end of the mechanical arm approaches the back glass sheet 600, the negative pressure generating mechanism is started to form a negative pressure in the suction cup, so that the surface of the back glass sheet 600 is tightly adsorbed. During the adsorption process, it is necessary to ensure that the contact area between the suction cup and the back glass sheet 600 is uniform, so as to avoid the falling of the back glass sheet 600 due to insufficient local adsorption force. After the adsorption is completed, the mechanical arm drives the back glass sheet 600 to move along the preset lifting and translation trajectory. During the translation process, the back glass sheet 600 can be kept in a horizontal state to prevent the glass sheet from being inclined to cause adsorption failure. When the back glass sheet 600 moves to directly above the glass combining station 710, the control device 1000 confirms that the back glass sheet 600 reaches the target position through the position detection element such as the second image acquisition device, and at this time the mechanical arm stops moving.

[0102] When the front glass sheet 500 and the back glass sheet 600 both reach the glass combining station 710, the back glass sheet 600 is above the front glass sheet 500, and a preset safe distance is maintained between the two to avoid contact before alignment.

[0103] The conveying device 800 can stably and safely complete the conveying of the back glass sheet 600 by means of the negative pressure suction cup and the precise movement along the preset track, avoid damage to the edges of the glass sheet caused by the traditional mechanical clamping method, and maintain the horizontal state of the back glass sheet 600 during the conveying process to prevent the glass sheet from tilting or falling and improve the safety and reliability of the conveying of the back glass sheet 600. The back glass sheet 600 hovers above the front glass sheet 500 and maintains a safe distance, which can avoid surface scratches or position misalignment caused by contact between the two before alignment, and reserve sufficient space for subsequent alignment operations.

[0104] It is worth noting that steps S100 and S200 have no sequence, that is, steps S100 and S200 can be executed simultaneously, or step S100 can be executed first, or step S200 can be executed first, which is not limited here.

[0105] S300, control the moving device 900 to drive the corresponding alignment device to move to the glass combining station 710.

[0106] The control device 1000 sends a driving signal to the moving device 900 after confirming that the front glass sheet 500 and the back glass sheet 600 are in place. The moving device 900 is fixedly connected with the alignment device, and after the moving device 900 is started, it drives the alignment device to move to the glass combining station 710 according to the preset moving direction and speed. When the alignment device gradually contacts the side edges of the front glass sheet 500 and the back glass sheet 600 and continues to move to the target position, the moving device 900 stops running, and the alignment device remains at the current position to align the positions of the front glass sheet 500 and the back glass sheet 600 to make them centered and aligned.

[0107] The moving device 900 drives the alignment device to move precisely to the glass combining station 710, and the moving distance of the alignment device is controlled by the position detection element to ensure that the alignment device can effectively contact the side edges of the glass sheet to realize alignment and will not cause damage to the glass sheet due to excessive pressure. The synchronous alignment of the alignment device to the front glass sheet 500 and the back glass sheet 600 can quickly eliminate the positional deviation of the two, make their side edges aligned, lay a good foundation for subsequent stacking, and improve the overall precision of glass combining.

[0108] S400, after determining that the alignment device moves to the glass combining station 710, control the conveying device 800 to release the back glass sheet 600.

[0109] Exemplarily, after receiving the alignment signal sent by the moving device 900, the control device 1000 can secondarily confirm the alignment state of the front glass sheet 500 and the back glass sheet 600 through the image acquisition element. If the image shows that the alignment deviation of the two sides is within the allowable range, it is determined that the alignment is completed. Subsequently, the control device 1000 sends a release signal to the carrying device 800, and the negative pressure generating mechanism of the carrying device 800 stops working, and the negative pressure in the suction cup gradually disappears, and the adsorption force between the suction cup and the back glass sheet 600 is released. Under the action of gravity, the back glass sheet 600 slowly falls and is placed stably on the upper surface of the front glass sheet 500. During the placement process, it is necessary to ensure that the back glass sheet 600 falls vertically to avoid misalignment with the front glass sheet 500 due to deviation during the falling process. After the back glass sheet 600 is completely placed on the front glass sheet 500, the mechanical arm of the carrying device 800 moves away from the glass combining station 710 according to the preset trajectory and returns to the initial standby position, waiting for the next carrying instruction.

[0110] Releasing the back glass sheet 600 after confirming that the alignment is completed can ensure that the back glass sheet 600 is already in an aligned state with the front glass sheet 500 when being stacked, avoiding the need for secondary adjustment due to position deviation after stacking and reducing the wear of the glass sheet during the adjustment process. Slow and stable placement of the back glass sheet 600 on the front glass sheet 500 can avoid damage to the glass sheet caused by falling impact, and the carrying device 800 moves away in time after being released, which does not affect the subsequent glass combining process. The overall process is coherent and efficient, effectively improving the production efficiency and product yield of the glass combining equipment and reducing the breakage rate of the glass sheet during the production process.

[0111] According to one embodiment of the present application, before controlling the moving device 900 to drive the corresponding alignment device to move to the glass combining station 710, the method further comprises:

[0112] S210, acquiring image information of the front glass sheet 500 and the back glass sheet 600, and determining an adjustment parameter based on the image information, the adjustment parameter including a target rotation angle of the first eccentric wheel 120 and the second eccentric wheel 130;

[0113] S220, controlling the adjustment mechanism 140 to adjust the first eccentric wheel 120 and the second eccentric wheel 130 to the target rotation angle.

[0114] Exemplarily, before the control mobile device 900 drives the corresponding correction device to move to the annealing station 710, the image acquisition device 1100 is started, and the image acquisition device 1100 performs image shooting on the front glass sheet 500 at the annealing station 710 and the back glass sheet 600 in the conveying state to obtain image information containing the contour of the front glass sheet 500 and the back glass sheet 600. After the obtained image information is transmitted to the control device 1000, the control device 1000 processes the image information through image recognition technology, recognizes the edge contour of the front glass sheet 500 and the edge contour of the back glass sheet 600, and further determines the size parameters of the front glass sheet 500 and the back glass sheet 600 in the correction direction respectively. According to the preset corresponding relationship, that is, the matching relationship between different front glass sheet 500 sizes and the rotation angle of the first eccentric wheel 120, and the matching relationship between different back glass sheet 600 sizes and the rotation angle of the second eccentric wheel 130, the control device 1000 calculates the adjustment parameter, which includes the target rotation angle of the first eccentric wheel 120 that can adapt to the size of the current front glass sheet 500, and the target rotation angle of the second eccentric wheel 130 that can adapt to the size of the current back glass sheet 600. Subsequently, the control device 1000 sends a control signal to the adjustment mechanism 140, and after the adjustment mechanism 140 receives the signal, the first eccentric wheel 120 is driven to rotate to the corresponding target rotation angle and is fixed, and at the same time, the second eccentric wheel 130 is driven to rotate to the corresponding target rotation angle and is fixed, thereby completing the angle adjustment operation of the first eccentric wheel 120 and the second eccentric wheel 130.

[0115] Before the correction device moves, the angles of the first eccentric wheel 120 and the second eccentric wheel 130 are adjusted according to the glass sheet image information, which can ensure that when the correction device contacts the front glass sheet 500 and the back glass sheet 600, the first eccentric wheel 120 and the second eccentric wheel 130 are already in the best angle state that adapts to the current glass sheet size, thereby avoiding excessive extrusion of the front glass sheet 500 and the back glass sheet 600 during the correction process due to the angle not adapting. The size information of the front glass sheet 500 and the back glass sheet 600 is obtained through image recognition, which is more accurate and efficient than manual measurement, reduces the influence of manual measurement error on the adjustment of the eccentric wheel angle, and further improves the accuracy of the angle adjustment of the first eccentric wheel 120 and the second eccentric wheel 130. The target rotation angle is determined based on the preset corresponding relationship, which makes the adjustment process more standardized and repeatable, ensures that the angle adjustment results of the first eccentric wheel 120 and the second eccentric wheel 130 are consistent when different operators or different batches of operations are performed, and guarantees the stability of the correction effect, thereby effectively reducing the breakage probability of the front glass sheet 500 and the back glass sheet 600 during the correction process and improving the product yield.

[0116] According to one embodiment of the present application, the adjustment parameter is determined based on the image information, which includes:

[0117] Determine the distance between the two sides of the front glass 500 and the distance between the two sides of the back glass 600 based on the image information.

[0118] Determine the target rotation angle of the first eccentric wheel 120 based on the corresponding relationship between the distance between the two sides of the front glass 500 and the rotation angle of the first eccentric wheel 120, and determine the target rotation angle of the second eccentric wheel 130 based on the pre-stored corresponding relationship between the distance between the two sides of the back glass 600 and the rotation angle of the second eccentric wheel 130.

[0119] Exemplarily, after receiving the first image information transmitted by the first image acquisition device and the second image information transmitted by the second image acquisition device, the control device 1000 performs edge detection processing on the first image information, identifies the position coordinates of the two sides of the front glass 500 in the image, and calculates the actual distance between the two sides of the front glass 500 according to the conversion ratio of image pixels to actual size. Similarly, the second image information is subjected to edge detection processing, the position coordinates of the two sides of the back glass 600 in the image are identified, and the actual distance between the two sides of the back glass 600 is calculated in combination with the same conversion ratio. The control device 1000 internally pre-stores two sets of corresponding relationship data, the first set being the corresponding relationship data between the distance between the two sides of the front glass 500 and the rotation angle of the first eccentric wheel 120, which can be recorded after a large number of experimental tests on the best angle of the first eccentric wheel 120 adapted to different sizes of the front glass 500; the second set being the corresponding relationship data between the distance between the two sides of the back glass 600 and the rotation angle of the second eccentric wheel 130, which can also be obtained through experimental tests. The control device 1000 matches the actual distance between the two sides of the front glass 500 calculated with the first set of corresponding relationship data to determine the corresponding target rotation angle of the first eccentric wheel 120, and matches the actual distance between the two sides of the back glass 600 calculated with the second set of corresponding relationship data to determine the corresponding target rotation angle of the second eccentric wheel 130.

[0120] Calculating the distance between the two sides of the glass based on image information can directly obtain the key size parameter of the glass in the sizing direction, providing accurate data basis for determining the target angle of the eccentric wheel, and avoiding target angle deviation caused by inaccurate size information. The pre-stored corresponding relationship data is formed based on experimental tests, ensuring the scientificity and rationality of the matching of different sizes of glass and eccentric wheel angle, so that the determined target rotation angle can best adapt to the current glass and reduce the pressure on the glass during sizing. Establishing independent corresponding relationship data for the front glass 500 and the back glass 600 respectively and performing matching can independently and accurately adjust the angles of the first eccentric wheel 120 and the second eccentric wheel 130, better adapt to the possible size difference between the front glass 500 and the back glass 600, further improve the flexibility and adaptability of the sizing operation, and reduce the risk of glass breakage caused by size difference.

[0123] Optionally, in the case that the adjusting mechanism comprises locking members 141 corresponding to the first eccentric wheel 120 and the second eccentric wheel 130 respectively, the above-mentioned control of the rotation driving structures 142 corresponding to the first eccentric wheel 120 and the second eccentric wheel 130 respectively to drive the first eccentric wheel 120 and the second eccentric wheel 130 to rotate to the corresponding target rotation angles further comprises switching the locking members 141 to the unlocked state before the above-mentioned control of the rotation driving structures 142 corresponding to the first eccentric wheel 120 and the second eccentric wheel 130 respectively to drive the first eccentric wheel 120 and the second eccentric wheel 130 to rotate to the corresponding target rotation angles, and further comprises switching the locking members 141 to the locked state after the above-mentioned control of the rotation driving structures 142 corresponding to the first eccentric wheel 120 and the second eccentric wheel 130 respectively to drive the first eccentric wheel 120 and the second eccentric wheel 130 to rotate to the corresponding target rotation angles.

[0124] The above-mentioned switching of the locking members 141 to the unlocked state and the switching of the locking members 141 to the locked state can be achieved manually or automatically, for example, when the locking members 141 comprise locking bolts, the state switching can be achieved by manually rotating the locking bolts, and when the locking members 141 comprise telescopic members, the control device 1000 can be connected with the telescopic members, and the control device 1000 controls the telescopic members to switch the state.
