[0035] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0036] In the description of the present application, it should be noted that, unless otherwise specified, "multiple" means more than two; the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating directions or positional relationships, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the embodiments of the present application. In the description of the present application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0038] In order to better understand the technical solution of this application, Figures 1 to 11 The fastening device of the embodiment of the present application is described in detail.

[0039] In an embodiment of the present application, a fastening device is used to realize automated fastening of components of a photovoltaic bracket. More specifically, multiple strokes of the fastening device can be automatically controlled to move the fasteners to a predetermined position to perform fastening operations on the components of the photovoltaic bracket.

[0040] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a photovoltaic bracket provided by an embodiment of the present application is shown. Figure 2 A specific structural schematic diagram of a fastening device provided in one embodiment of the present application is shown.

[0041] Taking an exemplary structure of a photovoltaic bracket 20 as an example, the components of the photovoltaic bracket 20 include a purlin bracket 210, an inclined beam 220, and a purlin 230, and the fastening device 10 can be used to fasten the purlin bracket 210 and the purlin 230, or the purlin bracket 210 and the inclined beam 220. In addition, the fastening device 10 can also be used to fasten the purlin 230 to the inclined beam 220 after the purlin bracket 210 is fixed, or to fasten the inclined beam 220 to the purlin 230 after the purlin bracket 210 is fixed.

[0042] Optionally, the components of the photovoltaic bracket 20 may be connected by riveting, and the fasteners may be rivets, or the components of the photovoltaic bracket 20 may be connected by threads, and the fasteners may be studs, bolts, and screws, etc. The type of fastening connection is not limited here.

[0043] Taking the fastening of the purlin support 210 and the inclined beam 220 as an example, the fasteners loaded on the fastening device 10 can be set as bolts and nuts. The fastening device 10 is configured to drive the bolts and nuts to the two sides of the photovoltaic bracket 20 respectively. For example, the bolts can be driven to the top of the part of the purlin support 210, and the nuts can be driven to the bottom of the part of the inclined beam 220. The bolts are sequentially passed through the corresponding parts of the purlin support 210 and the inclined beam 220 and connected with the nuts to achieve the fastening of the purlin support 210 and the inclined beam 220.

[0044] The inclined beam 220 includes an upper flange and a lower flange arranged in parallel and a web arranged therebetween, one end of the upper flange and the lower flange are connected by the web, and the other ends of the upper flange and the lower flange extend toward each other to form a C-shaped opening structure. Due to the structural limitation of the inclined beam 220, when driving the fastener to the bottom of the inclined beam 220, three driving strokes need to be set.

[0045] The first driving stroke is to move the fastener in the vertical direction to the opening position of the inclined beam 220, the second driving stroke is to extend the fastener into the opening of the inclined beam 220 in the horizontal direction, and the third driving stroke is to move the fastener in the vertical direction and abut against the bottom of the upper flange of the inclined beam 220. If the fastener is installed on the photovoltaic bracket 20 by automatic driving, two strokes are required in the vertical direction, namely the first driving stroke and the third driving stroke, and these two strokes are separated by the horizontal stroke. One feasible way is to use a double cylinder to achieve a double stroke in the vertical direction, which is relatively expensive; another feasible way is to use retractable parts such as motors and screws, which is relatively expensive, and has complex control logic, numerous control signals, and low efficiency.

[0046] In order to solve the above technical problems, the present application provides a fastening device that uses a single drive member to achieve an interval double stroke. Figures 2 to 7The fastening device 10 includes a base 1, a first driving member 2, a second driving member 4 and a blocking member 5. The first driving member 2 is arranged on the base 1. The first driving member 2 has a movable end, and the movable end is provided with a receiving portion 3 for carrying the fastener. The first driving member 2 is used to drive the receiving portion 3 to approach or move away from the fastener to be fastened along the first direction X. The second driving member 4 is connected to the base 1 and is used to drive the base 1 to reciprocate along the second direction Z. The second direction Z intersects with the first direction X. The blocking member 5 is fixed in position along the second direction Z and is used to block the base 1 when the base 1 moves along the second direction Z for a first stroke. The movement of the movable end along the first direction X can drive the blocking member 5 to move to eliminate the obstruction to the base 1, so that the base 1 can continue to move along the second direction Z for a second stroke.

[0047] It should be noted that the fastening device 10 in the embodiment of the present application can be applied to the photovoltaic bracket 20. For example, the components on the photovoltaic bracket 20 can be used as the fasteners to achieve the installation of the photovoltaic bracket 20. The fastening device 10 can also be applied to other mechanisms that need to be fastened, as long as the mechanism has two strokes in the second direction Z separated by strokes in other directions.

[0048] With respect to the photovoltaic support 20 in the above embodiment, the first direction X can be set as a horizontal direction, and the second direction Z can be set as a vertical direction.

[0049] The fastening device 10 in the embodiment of the present application can drive the base 1 to rise along the second direction Z by the second driving member 4, and be blocked by the blocking member 5 after completing the first driving stroke. When the first driving member 2 drives the material receiving portion 3 to move along the first direction X, the movable end can abut against the blocking member 5 along the first direction X, and move the blocking member 5 during the second driving stroke, so that the blocking member 5 avoids the moving path of the base 1 along the second direction Z, and then the second driving member 4 can continue to drive the base 1 to rise along the second direction Z, and complete the third driving stroke to achieve the fastening of the photovoltaic bracket 20. In the case where the fastening device 10 moves forward along the second direction Z toward the fastener to be fastened, the above-mentioned first stroke includes the first driving stroke, and the above-mentioned second stroke includes the third driving stroke.

[0050] It can be understood that the fastening device 10 in the embodiment of the present application can separate the movement of the base 1 along the second direction Z into two strokes through the blocking member 5. Only when the blocking member 5 is removed can the base 1 continue to move along the second direction Z. It is not necessary to set up a double cylinder to achieve double-stroke control, and there is no need to use a motor for precise control, so that the drive structure and control logic of the fastening device 10 can be simplified, and the cost can be reduced. The removal of the blocking member 5 is by means of the predetermined movement of the movable end along the first direction X. Only after the predetermined stroke of the movable end along the first direction X is completed, in the example of the photovoltaic bracket 20, that is, after the fastener extends into the opening of the inclined beam 220 in the horizontal direction, the blocking member 5 is removed, so that the base 1 continues to move along the second direction Z, that is, the fastener is moved in the vertical direction and abuts against the lower upper flange of the inclined beam 220. Therefore, the removal of the blocking member 5 does not require the addition of additional drive components, which is conducive to reducing costs and simplifying control.

[0051] Optionally, the first driving member 2 and / or the second driving member 4 are configured as at least one of a driving cylinder and a driving oil cylinder. As an example, the second driving member 4 can be configured as a single air cylinder or a single oil cylinder. By providing the blocking member 5, the double-stroke control along the second direction Z can be achieved by only configuring the second driving member 4 as a single air cylinder. The driving structure is simple, the control is convenient, and the cost is low.

[0052] It can be understood that the movement of the movable end along the first direction X can drive the blocking member to move, which can be to drive the blocking member 5 to slide along the first direction X, or to drive the blocking member 5 to rotate around a certain rotation axis so that its position is adjustable, and the rotation axis intersects with the first direction X.

[0053] In some optional embodiments, the blocking member 5 has a first position and a second position on its moving path, and the fastening device 10 further includes a pusher 6, which is connected to the movable end of the first driving member 2, and is configured to push the blocking member 5 to switch from the first position to the second position, wherein the blocking member 5 blocks the base 1 in the first position and avoids the base 1 in the second position. Similarly, in the case where the blocking member 5 is arranged to rotate around a certain rotation axis, a pusher 6 may also be provided, and the movement of the pusher 6 along the first direction X will push the blocking member 5 to switch from the first position to the second position, wherein the blocking member 5 blocks the base 1 in the first position and avoids the base 1 in the second position.

[0054] Since the movable end of the first driving member 2 reciprocates along the first direction X, a pushing member 6 is provided at the movable end of the first driving member 2 to push the blocking member 5 from the first position to the second position, so as to realize double-stroke control of the fastening device 10 along the second direction Z.

[0055] Optionally, the pushing member 6 can be reused as a component of the movable end of the first driving member 2, or the pushing member 6 can be a component that is separately provided and connected to the movable end of the first driving member 2. It only needs to be able to push the blocking member 5 along the first direction X under the action of the movable end of the first driving member 2 so that the blocking member 5 moves from the first position to the second position.

[0056] As an optional embodiment, the fastening device 10 also includes a fixed seat 8, which is fixed at a position in the second direction Z and avoids the moving path of the base 1 along the second direction Z. The blocking member 5 is connected to the fixed seat 8 and can be moved relative to the fixed seat 8 along the first direction X to achieve the installation of the blocking member 5.

[0057] See also Figures 7 to 11 In some optional embodiments, the blocking member 5 includes a main body 51 and a first blocking portion 52 disposed on the main body 51 , and the first blocking portion 52 is configured to block the base 1 at a first position and avoid the base 1 at a second position.

[0058] The first blocking portion 52 extends from the main body 51 along the third direction Y, and the base 1 is provided with a protruding portion protruding along the third direction Y, and the third direction Y intersects with the first direction X and the second direction Z. In the first position, the first blocking portion 52 and the orthographic projection of the protruding portion along the second direction Z at least partially overlap, and in the second position, the first blocking portion 52 and the orthographic projection of the protruding portion along the second direction Z are misaligned.

[0059] Among them, the third direction Y is the direction of the base 1 toward the fixed base. By providing a protrusion on the base 1 along the third direction Y, the first blocking portion 52 can be made to avoid the moving path of the base 1 along the second direction Z only by moving the first blocking portion 52 to be offset with the protrusion along the second direction Z. This makes the structure simpler and more efficient.

[0060] In some optional embodiments, a follower 11 may be fixedly disposed on the base 1, and the follower 11 includes a first follower segment 111 and a second follower segment 112. The first follower segment 111 is connected to the base 1 and extends along a first direction X, and the second follower segment 112 is connected to the first follower segment 111 and extends along a third direction Y, so that the second follower segment 112 forms a protrusion relative to the base 1.

[0061] By configuring the follower 11 to be a connected first follower segment 111 and a second follower segment 112 , it is possible to form a protrusion through the second follower segment 112 while more conveniently adjusting the position of the protrusion along the first direction X through the first follower segment 111 to cooperate with the first blocking portion 52 .

[0062] Optionally, the follower 11 further includes a supporting rib 113, which is connected to the base 1 and supported below the first follower section 111 along the second direction Z to support and fix the follower 11 and improve the force reliability of the protrusion.

[0063] In some optional embodiments, the pusher 6 includes a first push section 61 and a second push section 62, wherein the first push section 61 is connected to the movable end of the first driving member 2 and extends along the second direction Z, and the second push section 62 is connected to the first push section 61 and can be configured to push the first blocking portion 52 through the second push section 62 to drive the blocking member 5 to switch from the first position to the second position. In other words, the first blocking portion 52 is used for both blocking the protrusion and abutting against the second push section 62, and such reuse can simplify the structural design of the blocking member.

[0064] Optionally, the second pushing section 62 may extend a preset distance along the first direction X to increase the size of the pushing member 6 along the first direction X, so that the second pushing section 62 can abut against the first blocking portion 52 along the first direction X while the movable end has a limited moving distance, thereby achieving movement of the first blocking portion 52. Of course, in some other embodiments, the second pushing section 62 may not extend a preset distance along the first direction X, but may directly extend from the first pushing section 61 along the third direction Y to abut against the first blocking portion 52.

[0065] By extending the first pushing section 61 along the second direction Z, the position of the second pushing section 62 relative to the protrusion along the second direction Z can be adjusted while the pushing member 6 is connected to the movable end of the first driving member 2. Therefore, when the base 1 moves along the first direction X, the position of the second pushing section 62 along the second direction Z is roughly flush with the position of the blocking member 5 along the second direction Z, so that it is easier to push the first blocking portion 52 along the first direction X by the second pushing section 62, thereby improving the reliability of the fastening device 10.

[0066] It is understandable that in some other embodiments, the second pushing section 62 can also drive the blocking member 5 to switch from the first position to the second position by pushing any position of the blocking member 5, for example, by pushing the main body 51. Compared with pushing other positions of the blocking member 5, pushing the first blocking portion 52 to move by the second pushing section 62 can more easily control the moving position of the blocking member 5 and simplify the structure of the blocking member 5. Therefore, for the convenience of description, the following description is based on the example of pushing the first blocking portion 52 by the second pushing section 62.

[0067] See also Figures 6 to 9In some optional embodiments, the fastening device 10 also includes a limiting member 7, the limiting member 7 includes a first limiting portion 71 and a second limiting portion 72 that are at least partially arranged relative to each other along the first direction X, and the blocking member 5 is at least partially arranged in a gap between the first limiting portion 71 and the second limiting portion 72, wherein the first limiting portion 71 is used to limit a first position of the blocking member 5, and the second limiting portion 72 is used to limit a second position of the blocking member 5.

[0068] By providing the first limiting portion 71 and the second limiting portion 72, the extreme moving position of the blocking member 5 along the first direction X can be limited, for example, the first position and the second position of the blocking member 5 can be limited, so as to further ensure the reliability of the fastening device 10 and avoid the blocking member 5 moving beyond the predetermined position, causing the fastening device 10 to get stuck, interfere, or even lose the blocking effect.

[0069] Optionally, the limiting member 7 is connected to the fixing seat 8 to facilitate installation of the limiting member 7 .

[0070] Furthermore, the position-limiting member 7 may further include a position-limiting body 73, the position-limiting body 73 is connected to the fixing seat 8, the first position-limiting portion 71 and the second position-limiting portion 72 are integrally arranged on the position-limiting body 73, and are protruded relative to the position-limiting body 73 along the second direction Z, so as to simplify the structure of the position-limiting member 7. Alternatively, the position-limiting body 73 may also be reused as the fixing seat 8, that is, the first position-limiting portion 71 and the second position-limiting portion 72 are protruded on the fixing seat 8, so as to limit the blocking member 5. That is, the setting form of the position-limiting member 7 can be adjusted according to the structure and position of the fixing seat 8 and the blocking member 5, and can meet the position-limiting requirements of the blocking member 5.

[0071] In some optional embodiments, in the first position, the blocking member 5 is magnetically connected or snap-connected to the first limiting portion 71 , and / or, in the second position, the blocking member 5 is magnetically connected or snap-connected to the second limiting portion 72 .

[0072] By setting up a magnetic connection or a snap connection, the blocking member 5 can be fixed in the first position or the second position, so that the position of the blocking member 5 remains relatively fixed when there is no external force, thereby avoiding uncontrollable position changes of the blocking member 5 due to equipment vibration and the like, avoiding loss of blocking effect, and the resulting malfunction of the fastening device 10, thereby improving the safety of the fastening device 10.

[0073] In some optional embodiments, the blocking member 5 also includes an extension portion 53, and the extension portion 53 and the first blocking portion 52 are respectively arranged on both sides of the main body portion 51 along the third direction Y, and the extension portion 53 at least partially extends into the gap between the first limiting portion 71 and the second limiting portion 72, so that the extension portion 53 can be used to cooperate with the limiting member 7 to achieve the limitation of the blocking member 5, thereby shortening the size of the limiting member 7 and simplifying the structure of the limiting member 7.

[0074] Optionally, the number of extension portions 53 is more than two and they are arranged at intervals along the first direction X. For example, the multiple extension portions 53 may include a first extension portion 531 and a second extension portion 532. In the first position, the first extension portion 531 is magnetically or snap-connected to the first limiting portion 71. In the second position, the second extension portion 532 is magnetically or snap-connected to the second limiting portion 72 to improve the reliability of the cooperation between the extension portion 53 and the limiting member 7.

[0075] It can be understood that the distance between the first extension portion 531 and the second extension portion 532 along the first direction X should be smaller than the distance between the first position and the second position along the first direction X to meet the movement requirements of the blocking member 5, and the specific positions of the first extension portion 531 and the second extension portion 532 and the specific distance between the two can be adjusted according to the movement requirements of the blocking member 5 and the structure of the limit member 7, and the present application does not make specific limitations on this.

[0076] See also Figures 1 to 11 , below, taking the fastening device 10 in an exemplary embodiment of the present application as an example, the workflow of installing the fastener on the photovoltaic bracket 20 is explained.

[0077] In the first step, the blocking member 5 is moved to the first position and is magnetically connected by the first limiting portion 71 of the limiting member 7. The base 1 is driven to rise in the second direction Z through the second driving member 4. When the material receiving portion 3 rises to the opening position of the inclined beam 220, the protrusion on the follower 11 is blocked by the first blocking portion 52, and the base 1 stops rising in the second direction Z. At this time, the first driving stroke is completed.

[0078] In the second step, the material receiving part 3 is driven to move along the first direction X by the first driving member 2, and the material receiving part 3 is extended into the opening position of the inclined beam 220, and at the same time, the pushing member 6 connected to the movable end of the first driving member 2 is driven to move along the first direction X. The pushing member 6 abuts against the first blocking part 52, and drives the blocking member 5 to move from the first position to the second position, and is magnetically connected to the second limiting part 72. At this time, the second driving stroke is completed.

[0079] In the third step, since the first blocking portion 52 avoids the moving path of the protrusion along the second direction Z, the second driving member 4 can continue to drive the base 1 to rise along the second direction Z. When the receiving portion 3 on the base 1 rises to the lower surface of the inclined beam 220, the base 1 stops rising along the second direction Z. At this time, the third driving stroke is completed and the photovoltaic bracket 20 can be tightened.

[0080] It is understandable that after the fastener is installed on the photovoltaic bracket 20, in some embodiments, the fastening device 10 needs to be reset, specifically including the reset of the base 1, the material receiving portion 3 and the blocking member 5 to control the next fastener to be fastened to the photovoltaic bracket 20.

[0081] In order to achieve the resetting of the blocking member 5, in some optional embodiments, the fastening device 10 also includes a resetting portion 54, which is connected to one of the pushing member 6 and the blocking member 5, and the pushing member 6 is configured to drive the blocking member 5 to switch from the second position to the first position through the resetting portion 54.

[0082] By connecting the reset portion 54 to one of the pusher 6 and the blocking member 5, when resetting the material receiving portion 3, the pusher 6 can be reused to synchronously drive the blocking member 5 to switch from the second position to the first position through the reset portion 54, thereby resetting the fastening device 10. The structure is simpler and the fastening efficiency can be improved.

[0083] Among them, the reset portion 54 is connected to one of the pushing member 6 and the blocking member 5. The reset portion 54 can be connected to the pushing member 6, and the blocking member 5 is at least partially located between the reset portion 54 and the pushing member 6 along the first direction X, so that when the pushing member 6 moves along the first direction X toward a direction away from the photovoltaic bracket 20, the first blocking portion 52 can be driven to move by the reset portion 54 to switch the blocking member 5 from the second position to the first position.

[0084] Alternatively, the reset portion 54 may be connected to the blocking member 5, and the pushing member 6 may be at least partially located between the reset portion 54 and the blocking member 5 along the first direction X, so that when the pushing member 6 moves along the first direction X toward a direction away from the photovoltaic bracket 20, the first blocking portion 52 may be driven to move by abutting against the reset portion 54, thereby switching the blocking member 5 from the second position to the first position.

[0085] When the reset portion 54 is connected to the blocking member 5, in some optional embodiments, the reset portion 54 is arranged on the main body portion 51, specifically, extends from the main body portion 51 along the third direction Y, and is arranged opposite to the first blocking portion 52 along the first direction X, thereby defining a gap between the reset portion 54 and the first blocking portion 52 along the first direction X, and the orthographic projection of the pushing member 6 along the second direction Z on the plane where the blocking member 5 is located is at least partially located in the gap between the first blocking portion 52 and the reset portion 54, thereby simplifying the structure of the reset portion 54 and making it simpler and more efficient.

[0086] The spacing between the first blocking portion 52 and the reset portion 54 along the first direction X is related to the stroke of the pusher 6, and the distance enables the pusher 6 to move between the first blocking portion 52 and the reset portion 54 along the first direction X. Preferably, the stroke of the blocking member 5 is smaller than the stroke of the pusher 6, that is, the pusher 6 contacts the first blocking portion 52 or the reset portion 54 when the stroke along the first direction X is about to be completed, so that the blocking member 5 switches positions, thereby reducing the size of the fixing seat and the blocking member 5 and simplifying the structural design of the two. In this case, the spacing between the first limiting portion 71 and the second limiting portion 72 along the first direction X can be smaller than the spacing between the first blocking portion 52 and the reset portion 54 along the first direction X.

[0087] It should be noted that, according to the application environment of the fasteners to be fastened, after the fastening is completed, in some embodiments, the fasteners such as the photovoltaic bracket can be removed first, so that the base 1 and the material receiving part 3 can be directly controlled by the first driving member 2 and the second driving member 4 to move in the opposite direction, so as to automatically reset the base 1, the material receiving part 3 and the blocking member 5. In this process, the stroke of the second driving member 4 along the second direction Z, that is, the vertical direction, can be continuous, and the above-mentioned reset part needs to have a certain length along the second direction Z, so that before or after the second driving member 4 moves in the opposite direction Z, it can also drive the blocking member 5 to switch from the second position to the first position by means of the movement of the movable end. In other embodiments, for example, after the fastening of the purlin 210 and the inclined beam 220 is achieved, the fasteners such as the photovoltaic bracket are not removed, so it is also necessary to perform automatic control of multiple strokes in the reverse process, so that the material receiving part 3 is reversely withdrawn from the opening of the inclined beam 220, so that the base 1, the material receiving part 3 and the blocking member 5 can be automatically reset.

[0088] See also Figures 7 to 11 For multi-stage stroke control in the reverse process, in some optional embodiments, the first blocking portion 52 is configured to block the positive movement of the base 1 along the second direction Z at the first position, and the pushing member 6 is configured to push the blocking member 5 from the first position to the second position during the positive movement along the first direction X toward the fastener to be fastened, so that the first blocking portion 52 avoids the base 1.

[0089] The blocking member 5 also includes a second blocking portion 55 arranged on the main body 51, and the second blocking portion 55 is configured to block the base 1 from moving in the second direction Z in the second position. The pushing member 6 is configured to push the blocking member 5 to switch from the second position to the first position during the reverse movement along the first direction X, so that the second blocking portion 55 avoids the base 1.

[0090] Similar to the first blocking portion 52, by setting the second blocking portion 55, two strokes can be formed in the second direction Z during the reverse movement of the base 1. Without manual operation, the material receiving portion 32 can reversely exit the opening of the inclined beam 220, thereby automatically resetting the fastening device 10.

[0091] Specifically, the second blocking portion 55 is spaced from the first blocking portion 52 along the second direction Z and is at least partially misaligned along the first direction X, and the second blocking portion 55 extends along the third direction Y. The distance between the second blocking portion 55 and the first blocking portion 52 along the second direction Z is greater than or equal to the size of the protrusion along the second direction Z. In the first position, the first blocking portion 52 at least partially overlaps with the orthographic projection of the protrusion along the second direction Z to prevent the protrusion from continuing to rise along the second direction Z, and the second blocking portion 55 is misaligned with the orthographic projection of the protrusion along the second direction Z; in the second position, the second blocking portion 55 at least partially overlaps with the orthographic projection of the protrusion along the second direction Z to prevent the protrusion from continuing to fall along the second direction Z, and the first blocking portion 52 is misaligned with the orthographic projection of the protrusion along the second direction Z. Specifically, the resetting of the fastening device 10 also includes three driving strokes. The following takes the fastening device 10 in an exemplary embodiment of the present application as an example to illustrate the workflow of resetting the fastening device 10.

[0092] In the first step, after completing the third driving stroke, the blocking member 5 is in the second position. At this time, the base 1 can be driven by the second driving member 4 to move in the opposite direction along the second direction Z. When the material receiving part 3 descends to the opening position of the inclined beam 220, the protrusion on the follower 11 is blocked by the second blocking part 55, and the descent of the base 1 along the second direction Z stops. At this time, the fourth driving stroke is completed.

[0093] In the second step, the first driving member 2 drives the material receiving portion 3 to move away from the photovoltaic bracket 20 along the first direction X, and makes the material receiving portion 3 disengage from the opening position of the inclined beam 220, and at the same time drives the pushing member 6 connected to the movable end of the first driving member 2 to move along the first direction X. The pushing member 6 drives the blocking member 5 to move from the second position to the first position through the resetting portion 54 and is magnetically connected to the first limiting portion 71. The protrusion has relative movement with the blocking member 5 in the gap between the second blocking portion 55 and the first blocking portion 52 along the second direction Z. The second blocking portion 55 avoids the moving path of the protrusion descending along the second direction Z. At this time, the fifth driving stroke is completed.

[0094] In the third step, the second driving member 4 drives the base 1 to continue to descend along the second direction Z to restore the original position. At this time, the base 1, the material receiving part 3 and the blocking member 5 are all reset, and the sixth driving stroke is completed.

[0095] When the fastening device 10 moves in the reverse direction away from the fastened component along the second direction Z, the first stroke includes the fourth driving stroke, and the second stroke includes the sixth driving stroke.

[0096] That is, by reusing the blocking member 5 , not only can the fastening device 10 achieve a double stroke in the positive direction along the second direction Z, but also a double stroke in the reverse direction, which has a simple structure and improves the working efficiency of the fastening device 10 .

In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
