Description

Technical Field

[0001] This application relates to the field of solar photovoltaic coating, specifically to a quick-release device and a coating carrier plate. Background Technology

[0002] In the loading / unloading section and the coating section, the contact points between the coating carrier and the drive rollers differ. When the coating carrier is in the coating section, the suspended portion is covered by the coating layer, which accumulates over time. Consequently, when the coating carrier is in the loading / unloading section, the contact between the drive rollers and the sides of the carrier where the coating layer has accumulated can easily cause dust to fall onto the coating layer of the substrate supported by the carrier, leading to cross-contamination of the coating layer on the substrate. This affects the uniformity of the coating layer on the outer surface of the substrate and the quality of the film formation. Therefore, it is necessary to clean the coating layer on the coating carrier. The problem is that the process of disassembling and assembling the coating carrier is time-consuming, resulting in prolonged downtime of the coating production line and affecting its production efficiency. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a quick-release device that enables rapid installation and removal of the protective plate.

[0004] This application also proposes a coated carrier plate having the above-mentioned quick-release device.

[0005] The quick-release device according to an embodiment of this application includes a first limiting component and a second limiting component;

[0006] A first limiting component is used to connect to the substrate of the coating carrier plate. The first limiting component includes a first driving member and a first limiting member connected along a first direction.

[0007] The second limiting component is used to connect with the guard plate. The second limiting component includes a second limiting member and a first elastic member. Along the first direction, the second limiting member includes a first side and a second side that are arranged opposite to each other. Along the second direction, the second limiting member includes a third side and a fourth side that are arranged opposite to each other. The first elastic member abuts against the fourth side. The first direction is perpendicular to the second direction.

[0008] Wherein, at least one of the first limiting member and the third side is provided with a guide wall. The guide wall is inclined relative to both the first direction and the second direction. The guide wall is used for the first limiting member and the second limiting member to abut against each other along the first direction. The first limiting member is configured to move relative to the second limiting member along the first direction, so as to drive the second limiting member to move from the first position to the second position along the second direction through the guide wall. The second limiting member is configured to further compress the first elastic member during the process from the first position to the second position, and to disengage from the abutment with the first limiting member at the second position.

[0009] The quick-release device includes an unlocked state and a locked state. In the locked state, the third side abuts against the first driving member along the second direction, and the second side abuts against the first limiting member along the first direction.

[0010] The quick-release device according to the embodiments of this application has at least the following beneficial effects: along the first direction, the first driving member is used to drive the first limiting member to move relative to the second limiting member along the first direction. Along the first direction, the first limiting member moves from the first side to the second side. During the movement, the first limiting member and the second limiting member are kept in contact through the guide wall, and the second limiting member moves from the first position to the second position. The first elastic member is further compressed until the first limiting member moves to the second side. After the first limiting member moves to the second side, the first limiting member and the second limiting member separate. The first elastic member is used to drive the second limiting member to reset from the second position to the first position after the first limiting member and the second limiting member separate, until the third side of the second limiting member abuts against the first driving member. At the same time, the second side can abut against the first limiting member along the first direction under the action of gravity, which is used to restrict the separation of the first limiting member and the second limiting member along the first direction. The quick-release device is locked to realize the connection between the substrate and the protective plate. Furthermore, in the locked state, the second limiting member is moved from the first position to the second position, the quick-release device is unlocked, and the second limiting member avoids the movement of the first limiting member along the first direction, allowing the first limiting member to move from the second side to the first side along the first direction. Therefore, the quick-release device in this application enables rapid assembly and disassembly between the coating carrier plate and the protective plate, which helps to shorten the downtime of the coating production line and improve the production efficiency of the coating operation.

[0016] The extension direction of the unlocking groove forms an angle with the second direction, and the angle is not equal to 90°. The second driving member is used to drive the unlocking protrusion to move along the second direction by rotation.

[0017] According to some embodiments of this application, the second driving member is further provided with a clearance through hole, and in the locked state, the first limiting member is placed in the clearance through hole.

[0018] According to some embodiments of this application, the first limiting component further includes a second elastic member, one end of which abuts against the first driving member along the first direction, and the other end of the second elastic member abuts against the substrate.

[0019] According to some embodiments of this application, the first driving member includes a first limiting part and a connecting part. The first limiting part is connected to the connecting part.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] The embodiments of this application are described below with reference to the accompanying drawings:

[0046] refer to Figures 1 to 10 According to an embodiment of this application, the coating carrier plate includes a substrate 300, a protective plate 400, and a quick-release device in the embodiment of this application. The substrate 300 includes a support portion 310 and a support portion 320. The support portion 310 is used to support the coating workpiece. The support portion 320 is connected to one side of the support portion 310 and is distributed around the outer periphery of the support portion 310. The support portion 320 is used to support the transmission roller. The protective plate 400 is connected to the support portion 320 through the quick-release device. The transmission roller supports the support portion 320 along the loading and unloading conveying direction through the protective plate 400.

[0047] Specifically, the coating carrier plate includes a loading / unloading section and a coating section during the coating process. In the loading / unloading section, the drive rollers contact the guard plate 400. In the coating section, the drive rollers contact the support part 320, and the guard plate 400 is suspended in the air. The coating layer covers the surface of the guard plate 400. The quick-release device can realize the quick disassembly and assembly between the guard plate 400 and the support part 320. Cleaning the coating layer on the surface of the guard plate 400 can ensure the normal operation of the coating process without having to remove the entire coating carrier plate for maintenance. This helps to shorten maintenance time and improve the production efficiency of the coating production line.

[0048] refer to Figures 1 to 3 According to an embodiment of this application, the quick-release device includes a first limiting component 100 and a second limiting component 200. The first limiting component 100 is used to connect with the substrate 300 of the coating carrier plate. The first limiting component 100 includes a first driving member 110 and a first limiting member 120 connected along a first direction. The second limiting member 210 is used to connect with a protective plate 400. The second limiting component 200 includes a second limiting member 210 and a first elastic member 220. Along the first direction, the second limiting member 210 includes a first side and a second side disposed opposite to each other. Along the second direction, the second limiting member 210 includes a third side and a fourth side disposed opposite to each other. Along the second direction, the first elastic member 220 abuts against the fourth side. The first direction is perpendicular to the second direction.

[0049] In this embodiment, at least one of the third sides of the first limiting member 120 and the second limiting member 210 is provided with a guide wall. The guide wall is inclined relative to both the first direction and the second direction. The guide wall is used for the first limiting member 120 and the second limiting member 210 to abut against each other in the first direction. The first limiting member 120 is configured to move relative to the second limiting member 210 in the first direction so as to drive the second limiting member 210 to move from the first position to the second position in the second direction through the guide wall. The second limiting member 210 is configured to further compress the first elastic member 220 in the process of moving from the first position to the second position, and to disengage from the abutment with the first limiting member 120 in the second position.

[0050] The quick-release device includes an unlocked state and a locked state. In the unlocked state, along the second direction, the guide wall is located on the side where the first limiting member 120 and the second limiting member 210 face each other. That is, when the first limiting member 120 is provided with a guide wall, along the second direction, the guide wall is located on the side of the first limiting member 120 facing the second limiting member 210; when the second limiting member 210 is provided with a guide wall, the guide wall is located on the third side of the second limiting member 210; when both the first limiting member 120 and the second limiting member 210 are provided with guide walls, the guide wall is located on the side where the first limiting member 120 and the second limiting member 210 face each other.

[0051] In the locked state, the third side of the second limiting member 210 abuts against the first driving member 110 along the second direction, and the second side of the second limiting member 210 abuts against the first limiting member 120 along the first direction, which is used to ensure that the substrate 300 and the guard plate 400 are connected through the first limiting component 100 and the second limiting component 200. Specifically, the first direction can be the vertical direction and the second direction can be the horizontal direction. The mutual abutment between the second limiting member 210 and the first limiting member 120 is used to restrict the first limiting member 120 from moving upward and separating from the second limiting member 210, thus ensuring the connection between the substrate 300 and the guard plate 400.

[0052] It should be noted that the aforementioned unlocked state refers to one of the positional states in which the first limiting component 100 and the second limiting component 200 are separated from each other (e.g., Figure 2 As shown in the figure, the description of the position of the quick-release device in the unlocked state in this application can be found in [reference]. Figure 2 Understand the positional relationships between the various structural components of the quick-release device. Figure 2 The positional relationship between the various parts of the quick-release device should not be interpreted as a restriction on the unlocked state.

[0053] The quick-release device of this application is further described below in conjunction with the switching between the unlocked and locked states:

[0054] refer to Figures 1 to 3The first driving member 110, driven by a force in a first direction, can drive the first limiting member 120 to move. The first driving member 110 is used to drive the first limiting member 120 to move from the first side to the second side of the second limiting member 210. The first limiting member 120 and the second limiting member 210 abut against the guide wall. Under the action of the guide wall, the second limiting member 210 is driven to move from the first position to the second position along the second direction to further compress the first elastic member 220. When the second limiting member 210 moves to the second position, the first limiting member 120 and the second limiting member 220... 210 Separation: After the first limiting member 120 and the second limiting member 210 separate, the first elastic member 220 rebounds and drives the second limiting member 210 to move from the second position to the first position until the second limiting member 210 abuts against the first driving member 110 along the second direction. Furthermore, under the action of the second limiting member 210's own gravity, the second side of the second limiting member 210 abuts against the first limiting member 120 along the first direction, preventing the first limiting member 120 and the second limiting member 210 from separating from each other along the first direction, thereby realizing the switching of the quick-release device from the unlocked state to the locked state.

[0055] In addition, when the protective plate 400 is removed, the second limiting member 210 is driven to move from the first position to the second position along the second direction until the second limiting member 210 separates from the first limiting member 120, thereby avoiding the movement of the first limiting member 120 along the first direction. The first limiting member 120 moves up along the first direction (i.e., moves from the second side to the first side), and the first limiting component 100 separates from the second limiting component 200. Thus, the quick-release device is switched from the locked state to the unlocked state.

[0056] It should also be noted that the first limiting member 120 drives the second limiting member 210 through the guide wall. Therefore, the tilt angle of the guide wall relative to the horizontal plane should be greater than the friction angle to ensure that the first limiting member 120 drives the second limiting member 210.

[0057] refer to Figures 1 to 3In some embodiments, the first limiting member 120 includes a first guide wall 121, a first side wall 122, and a second side wall 123. Along a first direction, the first side wall 122 is located on one side of the first limiting member 120, and the second side wall 123 is located on the opposite side of the first limiting member 120. The first guide wall 121 extends from the first side wall 122 to the second side wall 123. Along the first direction, from the first side wall 122 to the second side wall 123, the cross-sectional area of ​​the first limiting member 120 (the area of ​​the cross-section obtained by cutting the first limiting member 120 along a plane perpendicular to the first direction) gradually decreases. In the locked state, the second limiting member 210 abuts against the first side wall 122 along the first direction. Thus, the first limiting member 120 can drive the second limiting member 210 to move along the second direction from the first position to the second position via the first guide wall 121, so as to further compress the first elastic member 220. In the second position, the second limiting member 210 separates from the first guide wall 121, and the first elastic member 220 can rebound to drive the second limiting member 210 located in the second position to move along the second direction to the first position to abut against the first driving member 110. In addition, the second side of the second limiting member 210 also abuts against the first side wall 122 along the first direction to limit the separation of the first limiting member 120 and the second limiting member 210 along the first direction.

[0058] It should be noted that the first limiting member 120 can be a trapezoidal, frustum or other structure, the first side wall 122 and the second side wall 123 are set parallel to the horizontal plane, and the angle between the first guide wall 121 and the horizontal plane can be 45°.

[0059] refer to Figures 1 to 3 In some embodiments, the second limiting component 200 includes two second limiting members 210 and two first elastic members 220. Along a second direction, the two second limiting members 210 are spaced apart, and their third sides face each other. In the unlocked state, along the second direction, the first limiting member 120 is located between the third sides of the two second limiting members 210, with one first elastic member 220 abutting against the fourth side of one of the second limiting members 210, and the other first elastic member 220 abutting against the fourth side of the other second limiting member 210.

[0060] Therefore, the first driving member 110 drives the first limiting member 120 downward along the first direction, and the first limiting member 120 simultaneously drives the two second limiting members 210 to move in opposite directions along the second direction via the first guide wall 121, that is, from the first position to the second position. It should be noted that the first position and the second position are references formed by a single second limiting member 210, that is, each second limiting member 210 has a corresponding first position and a second position, and there is no mutual interference between the first position and the second position of the two second limiting members 210. One of the second limiting members 210 further compresses one of the first elastic members 220 along the second direction, and the other second limiting member 210 further compresses the other first elastic member 220 along the second direction, thereby avoiding the first limiting member 120. This continues until both second limiting members 210 move to a second position relative to themselves, at which point the first limiting member 120 separates from the two second limiting members 210. Subsequently, the two second limiting members 210 move closer to each other and reset along the second direction under the abutment of their respective first elastic members 220, until the third side of the two second limiting members 210 abuts the first driving member 110, and the second side of the two second limiting members 210 abuts the first limiting member 120, thereby locking the first limiting member 120 with the two second limiting members 210. This is beneficial for further improving the locking stability of the quick-release device.

[0061] Specifically, the first limiting member 120 can be a frustum shape or an isosceles trapezoid. Taking the first limiting member 120 as a frustum shape as an example, the first guide wall 121 is a curved wall surrounding the first limiting member 120.

[0062] refer to Figures 1 to 3 In some embodiments, the first limiting member 120 includes a first guide wall 121, and the second limiting member 210 includes a second guide wall 211. In the unlocked state, along the second direction, the first guide wall 121 is located on the side of the first limiting member 120 facing the second limiting member 210, and the second guide wall 211 is located on the side of the second limiting member 210 facing the first limiting member 120, that is, the third side of the second limiting member 210. At least a portion of the first guide wall 121 is arranged parallel to the second guide wall 211. Through the cooperation of the first guide wall 121 and the second guide wall 211, the first limiting member 120 drives the second limiting member 210 to move along the second direction more smoothly and effortlessly.

[0063] Specifically, the first limiting member 120 is a frustum structure, and the first guide wall 121 is the side wall of the first limiting member 120, that is, the first guide wall 121 is a curved wall. In the unlocked state, along the second direction, a part of the first guide wall 121 faces one of the second limiting members 210, and the other part of the first guide wall 121 faces the other second limiting member 210. The second guide wall 211 is an inclined plane, and the first guide wall 121 and the second limiting member 210 are in line contact, which is beneficial to drive the second limiting member 210 to move along the second direction more smoothly.

[0064] refer to Figures 1 to 3 In other embodiments, the first guide wall 121 and the second guide wall 211 have different included angles relative to the horizontal plane. The first limiting member 120 approaches the second limiting member 210 along the first direction. Through the cooperation of the first guide wall 121 and the second guide wall 211, the first limiting member 120 can drive the second limiting member 210 to move along the second direction. The second limiting member 210 can further compress the first elastic member 220. After the first guide wall 121 and the second guide wall 211 separate, the first elastic member 220 rebounds along the second direction to drive the second limiting member 210 to reset and abut against the first driving member 110.

[0065] refer to Figures 2 to 7 In some embodiments, the second limiting component 200 further includes a second driving member 230. The second driving member 230 has an unlocking groove 231, and the second side of the second limiting member 210 has an unlocking protrusion 212 that extends into the unlocking groove 231. In the unlocked state, along the first direction, the second driving member 230 is located on the second side of the second limiting member 210, and the second driving member 230 can rotate about the first direction as its axis of rotation. The unlocking groove 231 forms an angle with the second direction, and this angle is not equal to 90°. The second driving member 230 is used to drive the unlocking protrusion 212 to move along the second direction by rotation, thereby driving the second limiting member 210 to move along the second direction, thus unlocking the quick-release component.

[0066] Specifically, the unlocking groove 231 is a curved groove. Along the extension direction of the unlocking groove 231, from one end of the unlocking groove 231 to the other end, the center distance between the unlocking groove 231 and the second driving member 230 gradually increases or decreases. Every time the second driving member 230 rotates by an angle, the position of the unlocking protrusion 212 in the unlocking groove 231 changes. The groove wall of the unlocking groove 231 can drive the unlocking protrusion 212 to move along the second direction, thereby realizing the driving of the second limiting member 210.

[0067] refer to Figure 4 In other embodiments, the second drive member 230 has a rotating protrusion on the side opposite to the second limiting member 210, which facilitates the rotation of the second drive member 230 and makes the quick-release device easier to unlock.

[0068] refer to Figures 2 to 7 In other embodiments, the second driving member 230 is provided with two unlocking slots 231, and the second limiting component 200 includes two second limiting members 210. Each second limiting member 210 has an unlocking protrusion 212 on its second side. The unlocking protrusions 212 extend into the unlocking slots 231 in a corresponding manner. By rotating the second driving member 230, the two unlocking protrusions 212 can be driven to move in opposite directions along the second direction. Thus, the two second limiting members 210 move in opposite directions along the second direction, thereby unlocking the quick-release device.

[0069] refer to Figures 2 to 7 In some embodiments, the second drive member 230 is also provided with an avoidance through hole 232. In the locked state, the first limiting member 120 is placed in the avoidance through hole 232. The avoidance through hole 232 is used to avoid the first limiting member 120, making the quick release device more compact in the first direction.

[0070] refer to Figures 2 to 7 In some embodiments, the first limiting component 100 further includes a second elastic member 140. Along a first direction, one end of the second elastic member 140 abuts against the first driving member 110, and the opposite end of the second elastic member 140 abuts against the substrate 300. When the second limiting member 210 separates from the first limiting member 120, the second elastic member 140 rebounds along the first direction, driving the first limiting member 120 to move upwards along the first direction, thereby unlocking the quick-release device. Subsequently, the substrate 300 separates from the protective plate 400, facilitating maintenance of the protective plate 400. Compared to manually moving the first limiting member 120 upwards, the second elastic member 140's rebound driving the first limiting member 120 upwards makes unlocking the quick-release device more convenient and faster.

[0071] For example, the second elastic element 140 can be a spring, and the first driving element 110 can be a bolt. The first driving element 110 and the first limiting element 120 are connected by threads. The second elastic element 140 is sleeved on the outer peripheral wall of the first driving element 110. When the first driving element 110 is driven to move from the first side to the second side, the second elastic element 140 is further compressed. That is, the first driving element 110 drives the first limiting element 120 to move along the first direction to approach the second limiting element 210. The first limiting element 120 is connected by the first guide wall 121 and the second guide wall 211. When the first elastic member 140 is compressed to its maximum extent, the first guide wall 121 and the second guide wall 211 separate. The first elastic member 220 rebounds and drives the second limit member 210 to move along the second direction until the second limit member 210 abuts against the first drive member 110. The second elastic member 140 rebounds and drives the first limit member 120 to move along the first direction until it abuts against the second limit member 210. The quick-release device switches to the locked state.

[0072] Therefore, the second elastic member 140 can not only enable the first limiting member 120 and the second limiting member 210 to disengage in the first direction when the quick release device is unlocked, but also ensure that the first limiting member 120 and the second limiting member 210 abut against each other in the first direction when the quick release device is locked, which is beneficial to increasing the stability of the lock.

[0073] refer to Figures 1 to 7 In some embodiments, the first driving member 110 includes a first limiting part 111 and a connecting part 112. The first limiting part 111 is connected to the connecting part 112. The first limiting component 100 also includes a first plate 130. The first plate 130 is provided with a first through hole 131 and a second limiting part 132. The first through hole 131 penetrates the first plate 130 along a first direction. The second limiting part 132 is connected to the hole wall of the first through hole 131. Along the first direction, the first limiting part 111 is located on the side of the second limiting part 132 away from the first limiting member 120. The first driving member 110 is inserted into the first through hole 131 and detachably connected to the first limiting member 120 to ensure the installation of the first driving member 110 and the first limiting member 120. In addition, the cooperation between the first limiting part 111 and the second limiting part 132 can limit the pressing stroke of the first limiting member 120, making it easier to determine whether the quick release device has switched to the locked state.

[0074] It should be noted that the quick-release device can be connected to the substrate 300 through the first plate 130. The first plate 130 can also be part of the substrate 300, that is, the first through hole 131 and the second limiting part 132 are provided on the substrate 300.

[0075] refer to Figures 2 to 9In some embodiments, the second limiting component 200 further includes a second plate 240, which has a second through hole 241 and a guide groove 242. The second through hole 241 penetrates the second plate 240 along a first direction, and the guide groove 242 extends from the location of the second through hole 241 along a second direction. The second limiting member 210 is located in the guide groove 242 and is slidably connected to the second plate 240 through the guide groove 242.

[0076] Along the second direction, the first elastic member 220 is located at one end of the guide groove 242 opposite to the second through hole 241, and is used to abut against the fourth side of the second limiting member 210, and can drive the second limiting member 210 to reset along the second direction. The second plate 240 is used to provide mounting positions for structures such as the second limiting member 210 and the first elastic member 220.

[0077] It should be noted that the second plate 240 can be used to connect the guard plate 400, or it can be part of the guard plate 400. That is, the guard plate 400 has a second through hole 241 and a guide groove 242 for the installation of structures such as the second limiting member 210 and the first elastic member 220.

[0078] refer to Figures 2 to 9 In some other embodiments, the second plate 240 is provided with two guide grooves 242. The two guide grooves 242 extend in opposite directions from the location of the second through hole 241 along the second direction. Each guide groove 242 can accommodate the second limiting member 210, so as to realize the movable connection between the second limiting member 210 and the second plate 240.

[0079] Specifically, the guide groove 242 can be a dovetail groove. The guide groove 242 is transversely cut along a plane perpendicular to the second direction. The shape of the cross section of the second limiting member 210 matches the shape of the dovetail groove to ensure a sliding fit between the second limiting member 210 and the guide groove 242.

[0080] In addition, along the second direction, each second limiting member 210 abuts against a first elastic member 220 on the side opposite to the second through hole 241. The first elastic member 220 is used to provide a reset elastic force for the second limiting member 210 to move and reset along the second direction, ensuring the reset of the two second limiting members 210 and realizing the locking function of the quick-release device.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
