Description

Technical Field

[0001] This application relates to the field of photovoltaic manufacturing equipment, and particularly to a film laying device. Background Art

[0002] When manufacturing a photovoltaic module, a film needs to be laid on the photovoltaic module to isolate air and moisture. There are protruding leads on the photovoltaic module that need to pass through holes in the film.

[0003] Since the film itself is a flexible material and the tension of the film is constantly changing during the stretching process, the shape and position of the holes are prone to fluctuations. As a result, after the film is laid on the photovoltaic module, the film will stick to the leads, which is not conducive to the subsequent installation of the junction box by the installer. Currently, it takes a lot of time and effort for the feeding personnel to make manual adjustments. Utility Model Content

[0004] This application provides a film laying device to improve the accuracy and efficiency of the leads passing through the holes in the film during film laying, making the film laying process more intelligent.

[0005] This application provides a film laying device, which includes:

[0024] One laser and one photographing mechanism are correspondingly arranged on one side of each base facing the photovoltaic module.

[0025] In the above technical solution, by arranging the support frame and the fixing blocks and the bases on the support frame, the laser and the photographing mechanism can be fixedly installed.

DETAILED DESCRIPTION

[0040] The present application is further described in detail below through the accompanying drawings and embodiments. Through these descriptions, the characteristics and advantages of the present application will become clearer and more specific.

[0041] The word "exemplary" is used exclusively herein to mean "serving as an example, embodiment, or illustration." Any embodiment described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise noted.

[0042] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0043] To facilitate understanding of the adhesive film laying device provided in the embodiment of the present application, its application scenario is first described. The adhesive film laying device is used in the process of laying adhesive film for making photovoltaic modules, and is used as a device for laying adhesive film. However, when the current adhesive film laying device is laying the adhesive film, since the adhesive film itself is made of flexible material and the tension is constantly changing during the stretching process, the shape and position of the hole are prone to fluctuations. Therefore, the adhesive film is prone to deviation when the hole is dropped, and the film will stick to the lead after the hole is dropped. To this end, the embodiment of the present application provides a kind of adhesive film laying device, which is used to improve the accuracy and efficiency of the lead passing through the film hole when laying the film, so that the film laying process is more intelligent. It is described in detail below in conjunction with specific drawings and embodiments.

[0044] For reference Figure 1 and Figure 2 , Figure 1 A schematic diagram showing the effect of laser irradiation of leads in the adhesive film laying device provided in an embodiment of the present application is shown. Figure 2 Schematic diagram of the effect of laser beam irradiating photovoltaic modules in the film laying device provided in an embodiment of the present application.

[0045] The embodiment of the present application illustrates a film laying device. The film laying device includes a laser 1. Among them, the laser 1 in the embodiment of the present application specifically refers to a device or apparatus that generates laser radiation. Exemplarily, the laser 1 emits a laser beam 11. The laser beam 11 emitted by the laser 1 has the characteristics of good monochromaticity, good directionality and high brightness.

[0046] The number of lasers 1 is equal to and in one-to-one correspondence with the number of leads 61 on the photovoltaic module 6, and the laser 1 is used to irradiate the corresponding lead 61. Wherein, the lead 61 in the embodiment of the present application specifically refers to a structure connected to the individual solar cells in the photovoltaic module 6, and the lead 61 is used to convey the electric energy generated by the individual solar cells.

[0047] Reference Figure 3 , Figure 3 Fig. shows a schematic diagram of the positional relationship between the laser beam and the film hole in the film laying device provided by the embodiment of the present application.

[0048] During the manufacturing process of the photovoltaic module 6, a plurality of leads 61 protruding from the photovoltaic module 6 are provided on the photovoltaic module 6. It is necessary to lay a film 62 for sealing on the photovoltaic module 6 to isolate air and moisture, improve the sealing performance of the photovoltaic module 6, and thus extend the service life of the photovoltaic module 6. In order to prevent the film 62 from interfering with the leads 61, film holes 621 are formed in the film 62 so that when the film 62 is laid, the leads 61 pass through the film holes 621 and are not adhered to the film 62.

[0049] By setting the number of lasers 1 to be equal to and in one-to-one correspondence with the number of leads 61 on the photovoltaic module 6, and the laser 1 being used to irradiate the corresponding lead 61, when the film 62 moves to the position where the film hole 621 and the lead 61 are arranged corresponding to the extension direction of the laser beam 11, after the film 62 is laid on the photovoltaic module 6, the film 62 does not interfere with the lead 61.

[0050] The film laying device in the embodiment of the present application further includes a photographing mechanism 2. Wherein, the photographing mechanism 2 is used to photograph the positional relationship between the laser beam 11 emitted by the laser 1 and the film hole 621 on the film 62. It should be noted that there are three positional relationships between the laser beam 11 emitted by the laser 1 and the film hole 621 on the film 62;

[0051] The first positional relationship: the laser beam 11 emitted by the laser 1 completely passes through the film hole 621 on the film 62;

[0052] The second positional relationship: the laser beam 11 emitted by the laser 1 completely irradiates on the film 62;

[0053] The third positional relationship: the laser beam 11 emitted by the laser 1 does not completely pass through the film hole 621 on the film 62, that is, a part of the laser beam 11 passes through the film hole 621 on the film 62, and another part of the laser beam 11 irradiates on the film 62.

[0054] The photographing mechanism 2 in the embodiment of the present application specifically refers to a device that forms and records an image using the principle of optical imaging, such as a camera.

[0055] In the above technical solution, since the number of lasers 1 is equal to and corresponds one-to-one with the number of leads 61 on the photovoltaic module 6, the laser 1 irradiates the corresponding lead 61. Therefore, by setting up the photographing mechanism 2 to photograph the position between the laser beam 11 emitted by the laser 1 and the film holes 621 on the adhesive film 62, it is possible to obtain whether the lead 61 and the film holes 621 are arranged corresponding to each other along the extending direction of the laser beam 11. If the lead 61 and the film holes 621 are arranged corresponding to each other along the extending direction of the laser beam 11, after the adhesive film is laid on the photovoltaic module 6, the adhesive film 62 does not interfere with the lead 61; if the lead 61 is not arranged corresponding to the film holes 621 along the extending direction of the laser beam 11, after the adhesive film is laid on the photovoltaic module 6, the adhesive film 62 interferes with the lead 61.

[0056] Reference Figure 4 , Figure 4 shows a schematic structural view of the film stretching mechanism in the film laying device provided by the embodiment of the present application.

[0057] The film laying device in the embodiment of the present application further includes a film stretching mechanism 3. Among them, the film stretching mechanism 3 is used to clamp the adhesive film 62. The specific structure of the film stretching mechanism 3 is not limited in the embodiment of the present application, and any structure capable of clamping the adhesive film 62 is acceptable. For example: cylinder jaws, mechanical jaws, etc. In the embodiment of the present application, the specific structure of the film stretching mechanism 3 is taken as an example of cylinder jaws for illustration.

[0058] The film laying device in the embodiment of the present application further includes a first driving mechanism 4. Among them, the function of the first driving mechanism 4 is to drive the film stretching mechanism 3 and the adhesive film 62 clamped by the film stretching mechanism 3 to move on the first surface 5. The specific structure of the first driving mechanism 4 is not limited in the embodiment of the present application, and any structure capable of driving the film stretching mechanism 3 and the adhesive film 62 clamped by the film stretching mechanism 3 to move on the first surface 5 is acceptable, such as: pneumatic cylinders, hydraulic cylinders, telescopic rods, etc. In the embodiment of the present application, the specific structure of the first driving mechanism 4 is taken as an example of a hydraulic cylinder for illustration. Among them, Figure 2 it is shown in that the first surface 5 is parallel to the surface of the photovoltaic module 6 facing the laser 1, and the first surface 5 is located between the photovoltaic module 6 and the laser 1.

[0059] Specifically, the output end of the first driving mechanism 4 is connected to the film stretching mechanism 3. By providing the film stretching mechanism 3 and the first driving mechanism 4 for driving the film stretching mechanism 3, when the film hole 621 and the lead 61 are not arranged corresponding to each other along the extension direction of the laser beam 11 after the film 62 moves between the photovoltaic module 6 and the laser 1, the first driving mechanism 4 can drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move on the first surface 5 to a position where the film hole 621 and the lead 61 are arranged corresponding to each other along the extension direction of the laser beam 11, which improves the situation that the lead 61 and the molten film 62 are adhered together during the lamination process after the film 62 is laid on the photovoltaic module 6. It should be noted that in the embodiments of the present application, the material of the film 62 can be selected from ethylene-vinyl acetate copolymer (EVA), ethylene-octene copolymer (POE), etc. Among them, when the photovoltaic module 6 is laminated in a laminator and heated to a certain temperature, the film made of ethylene-vinyl acetate copolymer (EVA) or ethylene-octene copolymer (POE) in the photovoltaic module 6 is in a molten state, realizing the bonding of the internal components of the photovoltaic module 6 and improving the sealing performance of the photovoltaic module 6.

[0060] The film laying device in the embodiments of the present application further includes a control module 9. Among them, the control module 9 is used to control the first driving mechanism 4 according to the position between the laser beam 11 and the film hole 621, so as to drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move on the first surface 5, so that the film hole 621 and the lead 61 are arranged opposite to each other in the first direction. Among them, Figure 2 it is shown in that the first direction is the extension direction of the laser beam 11, and the first direction is perpendicular to the first surface 5.

[0061] The control module 9 is a conventional control module installed with a single-chip microcomputer or a chip implanted with a software program in the embodiments of the present application, which can realize the control circuit and the electronic device for logical judgment, operation and execution of commands.

[0062] The control module 9, the laser 1, the photographing mechanism 2, the film stretching mechanism 3, the first driving mechanism 4 and the information transmission and control relationships among them involved in the embodiments of the present application can all be realized by those of ordinary skill in the art according to existing equipment and systems, and the specific implementation principles and the underlying architectures involved will not be introduced in detail.

[0063] The control module 9 receives the photos sent by the photographing mechanism 2, and controls the first driving mechanism 4 according to the position between the laser beam 11 and the film hole 621 in the photos, so as to drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move on the first surface 5, so that the film hole 621 and the lead 61 are arranged opposite to each other in the first direction. The control logic is the existing control logic.

[0064] During the operation of the film laying device:

[0065] First step, the control module 9 controls multiple lasers 1 to emit multiple laser beams 11 to irradiate corresponding multiple leads 61 on the photovoltaic module 6;

[0066] Second step, the control module 9 controls the photographing mechanism 2 to take a photo of the multiple laser beams 11 emitted by the multiple lasers 1 irradiating the corresponding multiple leads 61 on the photovoltaic module 6;

[0067] Third step, the control module 9 controls the film stretching mechanism 3 to clamp the film 62 provided with multiple film holes 621 and move it between the photovoltaic module 6 and the laser beams 11;

[0068] Fourth step, the control module 9 controls the photographing mechanism 2 to photograph the position of the multiple laser beams 11 and the multiple film holes 621, and the photographing mechanism 2 feeds back the position of the multiple laser beams 11 and the multiple film holes 621 to the control module 9;

[0069] Fifth step, the control module 9 controls the first driving mechanism 4 according to the position between the multiple laser beams 11 and the multiple film holes 621 to drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move on the first surface 5, so that the film holes 621 and the leads 61 are arranged opposite to each other in the first direction. Exemplarily, if the laser beams 11 emitted by the laser 1 completely irradiate on the film 62, or the laser beams 11 emitted by the laser 1 do not completely pass through the film holes 621 on the film 62, that is, a part of the laser beams 11 passes through the film holes 621 on the film 62 and another part of the laser beams 11 irradiates on the film 62, then the control module 9 controls the first driving mechanism 4 to drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move on the first surface 5 until the laser beams 11 emitted by the laser 1 completely pass through the film holes 621 on the film 62.

[0070] The film laying device in the embodiment of the present application further includes a carrier table 74. Wherein, the carrier table 74 is used to carry the photovoltaic module 6.

[0071] During the operation of the film laying device, the photovoltaic module 6 without the film 62 laid is transported to the surface of the carrier table 74 facing the laser 1.

[0072] The film laying device in the embodiment of the present application further includes a detection mechanism 75. Among them, the function of the detection mechanism 75 is to detect whether the photovoltaic module 6 is transported onto the carrier table 74. The specific structure of the detection mechanism 75 is not limited in the embodiment of the present application, and any structure that can detect the photovoltaic module 6 is acceptable, such as a photoelectric detector, an infrared detector, a light emitting and receiving device, etc. In the embodiment of the present application, the specific structure of the detection mechanism 75 is taken as an example of a photoelectric detector for illustration.

[0073] During the operation of the film laying device:

[0074] First step, after the detection mechanism 75 detects that the photovoltaic module 6 is transported onto the carrier table 74, the detection mechanism 75 sends a signal that the photovoltaic module 6 is transported onto the carrier table 74 to the control module 9;

[0075] Second step, after the control module 9 receives the signal that the photovoltaic module 6 is transported onto the carrier table 74, the control module 9 controls multiple lasers 1 to emit multiple laser beams 11 to irradiate corresponding multiple leads 61 on the photovoltaic module 6.

[0076] Among them, the control module 9, the detection mechanism 75, the lasers 1, the photographing mechanism 2, the film stretching mechanism 3, and the first driving mechanism 4 involved in the embodiment of the present application, as well as the information transmission and control relationships among them, can all be realized by those of ordinary skill in the art according to existing equipment and systems. The specific implementation principles and the underlying architectures involved will not be introduced in detail.

[0077] After the control module 9 receives the signal sent by the detection mechanism 75 that the photovoltaic module 6 is transported onto the carrier table 74, the control logic for controlling multiple lasers 1 to emit multiple laser beams 11 to irradiate corresponding multiple leads 61 on the photovoltaic module 6 is an existing control logic.

[0078] Reference Figure 5 , Figure 5 shows the effect diagram of the laser beam emitted by the laser in the film laying device provided by the embodiment of the present application irradiating on a plane.

[0079] In the film laying device in the embodiment of the present application, the diameter of the laser beam 11 emitted by the laser 1 is smaller than the minimum dimension of the film hole 621 along the second direction. Among them, Figure 2 shows that the second direction is parallel to the first surface 5 and the second direction passes through the central position 111 of the laser beam 11.

[0080] In the embodiment of the present application, the shape of the figure formed by the laser beam 11 irradiating on the plane is circular, that is, the laser beam 11 is cylindrical. The diameter of the laser beam 11 can be measured by the laser 1 emitting the laser beam 11 to irradiate on the plane to form a circular figure, and then measuring the diameter of the circular figure. Among them, the central position 111 of the laser beam 11 coincides with the position where the center of the circular figure is located.

[0081] In other embodiments, the shape of the figure formed by the laser beam 11 irradiating on the plane is a regular figure such as a square or a regular hexagon. Among them, the central position 111 of the laser beam 11 coincides with the position where the center of the regular figure is located.

[0082] By setting the diameter of the laser beam 11 emitted by the laser 1 to be smaller than the minimum size of the film hole 621 in the second direction, when the film 62 moves to the position where the film hole 621 corresponds to the lead 61 along the extending direction of the laser beam 11, the laser beam 11 emitted by the laser 1 can completely pass through the film hole 621 on the film 62. On the contrary, if the diameter of the laser beam 11 emitted by the laser 1 is greater than or equal to the minimum size of the film hole 621 in the second direction, it is not conducive to judging whether the film 62 moves to the position where the film hole 621 corresponds to the lead 61 along the extending direction of the laser beam 11, and thus it is not conducive to judging whether the film 62 interferes with the lead 61 after the film 62 is laid on the photovoltaic module 6.

[0083] Since the field of view angle of the photographing mechanism 2 is limited and the image outside the field of view angle of the photographing mechanism 2 cannot be photographed, the number of photographing mechanisms 2 in the film laying device in the embodiment of the present application is equal to the number of leads 61 and they are in one-to-one correspondence. It should be noted that the field of view angle in the embodiment of the present application specifically refers to, in an optical instrument, the angle formed by two edges of the maximum range through which the image of the measured target can pass through the lens with the vertex of the lens of the optical instrument. Among them, the optical instrument is the photographing mechanism 2 of the present application.

[0084] Specifically, each lead 61 corresponds to a photographing mechanism 2. At the same time, since each lead 61 corresponds to a photographing mechanism 2, the angle formed by the connection line between each lead 61 and the corresponding photographing mechanism 2 and the connection line between each lead 61 and the corresponding laser 1 is smaller, and the position situation between the laser beam 11 emitted by the laser 1 and the film hole 621 photographed by the photographing mechanism 2 can better reflect whether the laser beam 11 emitted by the laser 1 completely passes through the film hole 621 on the film 62. On the contrary, if the angle formed by the connection line between each lead 61 and the corresponding photographing mechanism 2 and the connection line between each lead 61 and the corresponding laser 1 is larger, then correspondingly, the photographing angle of the photographing mechanism 2 is more deviated, so it cannot well reflect whether the laser beam 11 emitted by the laser 1 completely passes through the film hole 621 on the film 62.

[0085] The film laying device in the embodiment of the present application further includes a support frame 71. Among them, the support frame 71 specifically refers to the foundation of the film laying device in the embodiment of the present application, and is used to install components such as the laser 1, the photographing mechanism 2, and the detection mechanism 75. In the embodiment of the present application, the installation foundation of components such as the laser 1, the photographing mechanism 2, and the detection mechanism 75 in the film laying device is collectively referred to as the support frame 71. In actual use, the specific structure of the support frame 71 can be adjusted adaptively according to the components to be installed.

[0086] The film laying device in the embodiment of the present application further includes fixing blocks 72. Among them, the function of the fixing blocks 72 is to fix components such as the laser 1, the photographing mechanism 2, and the detection mechanism 75 on the support frame 71. The number of the fixing blocks 72 is multiple. Multiple fixing blocks 72 specifically refer to two or more fixing blocks 72 in the embodiment of the present application, such as: two fixing blocks 72, three fixing blocks 72, four fixing blocks 72, five fixing blocks 72, six fixing blocks 72, seven fixing blocks 72, eight fixing blocks 72, etc. In the embodiment of the present application, the case where the number of the fixing blocks 72 is three is taken as an example for illustration.

[0087] Specifically, multiple fixing blocks 72 are arranged at intervals on the support frame 71. One laser 1 and one photographing mechanism 2 are correspondingly arranged on one side of each fixing block 72 facing the photovoltaic module 6.

[0088] As an alternative scheme, multiple fixing blocks 72 are fixedly arranged at intervals on the support frame 71;

[0089] As another alternative scheme, multiple fixing blocks 72 are detachably arranged at intervals on the support frame 71;

[0090] As yet another alternative scheme, multiple fixing blocks 72 are arranged at intervals and can slide and be fixed on the support frame 71.

[0091] The film laying device further includes a base 73. Among them, the function of the base 73 is to provide a mounting seat for the laser 1 and the photographing mechanism 2. The number of the bases 73 is multiple. Multiple bases 73 specifically refer to two or more bases 73 in the embodiment of the present application, such as: two bases 73, three bases 73, four bases 73, five bases 73, six bases 73, seven bases 73, eight bases 73, etc. In the embodiment of the present application, the case where the number of the bases 73 is three is taken as an example for illustration.

[0092] Specifically, multiple bases 73 are correspondingly arranged on one side of multiple fixing blocks 72 facing the photovoltaic module 6.

[0093] One laser 1 and one photographing mechanism 2 are correspondingly arranged on one side of each base 73 facing the photovoltaic module 6.

[0094] One side of the base 73 facing the photovoltaic module 6 is a planar structure, and the planar structure is parallel to the first surface 5. By setting one side of the base 73 facing the photovoltaic module 6 as a planar structure and the planar structure being parallel to the first surface 5, the laser beam 11 emitted by the laser 1 can be perpendicular to the first surface 5, and even if there is an error, it should be within the allowable error range. It also makes the angle at which the photographing mechanism 2 photographs the corresponding lead 61 not be too deviated. Even if the angle is deviated, it is within the field of view angle of the lens.

[0095] In the embodiment of the present application, the control module 9 is connected to the laser 1. Among them, there are various connection methods between the control module 9 and the laser 1, such as: electrical connection, signal connection, network connection, etc. In the embodiment of the present application, the control module 9 and the laser 1 are connected by signal connection.

[0096] Specifically, the control module 9 is used to control the laser 1 to emit the laser beam 11.

[0097] During the working process of the film laying device, after the photovoltaic module 6 is transported to the surface of the carrier 74 facing the laser 1, the control module 9 controls the laser 1 to emit the laser beam 11 to irradiate on the lead 61.

[0098] In the embodiment of the present application, the control module 9 is connected to the photographing mechanism 2. Among them, there are various connection methods between the control module 9 and the photographing mechanism 2, such as: electrical connection, signal connection, network connection, etc. In the embodiment of the present application, the control module 9 and the photographing mechanism 2 are connected by signal connection.

[0099] Specifically, the control module 9 is used to control the photographing mechanism 2 to take pictures;

[0100] The control module 9 is further used to receive and process the pictures sent by the photographing mechanism 2. It should be noted that the control module 9 processing the pictures sent by the photographing mechanism 2 in the embodiment of the present application specifically refers to the control module 9 judging whether the multiple laser beams 11 completely pass through the corresponding film holes 621 according to the position relationship between the multiple laser beams 11 and the multiple film holes 621 in the picture. Among them, the chip enabling the control module 9 to achieve this function is a chip with image recognition function, and a chip of model MA2450 ZIP7 can be selected.

[0101] During the working process of the film laying device, after the control module 9 controls the laser 1 to emit the laser beam 11 to irradiate on the lead 61, the control module 9 controls the photographing mechanism 2 to take a picture of the laser beam 11 irradiating on the lead 61. The control module 9 receives the picture of the laser beam 11 irradiating on the lead 61 sent by the photographing mechanism 2.

[0102] In the embodiment of the present application, the control module 9 is connected to the first driving mechanism 4. Among them, there are various connection methods between the control module 9 and the first driving mechanism 4, such as: electrical connection, signal connection, network connection, etc. In the embodiment of the present application, the control module 9 and the first driving mechanism 4 are connected by signal connection.

[0103] Specifically, the control module 9 is used to control the first driving mechanism 4 to drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move on the first surface 5.

[0104] During the working process of the film laying device, the control module 9 controls the first driving mechanism 4 to drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move to a predetermined position on the first surface 5. It should be noted that the predetermined position in the embodiment of the present application specifically refers to the position where the film stretching mechanism 3 clamping the film 62 is designed in advance to move between the photovoltaic module 6 and the laser 1 on the first surface 5.

[0105] There are two situations where the control module 9 controls the first driving mechanism 4 to drive the film stretching mechanism 3 and the film 62 clamped by the film stretching mechanism 3 to move to a predetermined position on the first surface 5:

[0106] The first situation: The film holes 621 on the film 62 at the predetermined position are arranged corresponding to the leads 61 on the photovoltaic module 6 along the first direction. Then, the control module 9 controls the photographing mechanism 2 to photograph the position situation between the laser beam 11 emitted by the laser 1 and the film holes 621 on the film 62.

[0107] The second situation: The film holes 621 on the film 62 at the predetermined position are not arranged corresponding to the leads 61 on the photovoltaic module 6 along the first direction. Then, the control module 9 controls the photographing mechanism 2 to photograph the position situation between the laser beam 11 emitted by the laser 1 and the film holes 621 on the film 62. Since the film holes 621 on the film 62 are not arranged corresponding to the leads 61 on the photovoltaic module 6 along the first direction, the laser beam 11 does not completely pass through the film holes 621, that is, at least part of the laser beam 11 irradiates on the film 62.

[0108] Reference Figure 6 , Figure 6 shows a side view of the film laying device provided by the embodiment of the present application.

[0109] In the embodiment of the present application, the film laying device further includes a second driving mechanism 8. The function of the second driving mechanism 8 is to drive the first driving mechanism 4 to move in the first direction. The specific structure of the second driving mechanism 8 is not limited in the embodiment of the present application, and any structure capable of driving the first driving mechanism 4 to move in the first direction is acceptable, such as a pneumatic cylinder, a hydraulic cylinder, a telescopic rod, etc. In the embodiment of the present application, the specific structure of the second driving mechanism 8 is taken as a hydraulic cylinder for illustration.

[0110] Specifically, the output end of the second driving mechanism 8 is connected to the first driving mechanism 4 to drive the first driving mechanism 4 to move in the first direction.
