Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a glass front and back detection device. Background Technology

[0002] A photovoltaic (PV) module is a device that converts solar energy into electrical energy. Currently, glass encapsulation dominates the PV module market. Glass-encapsulated PV modules typically consist of a stacked glass backsheet, a first encapsulating film layer, a cell string, a second encapsulating film layer, and a glass cover. With technological advancements, the design of PV glass has become increasingly sophisticated. In the design process, in addition to considering the glass's mechanical strength and high light transmittance, the adhesion between the glass and the encapsulating film layer must also be considered to prevent delamination and other failures during long-term outdoor use. Therefore, the front and back of PV glass are generally divided into smooth and rough surfaces.

[0003] In actual production, the correct orientation of the glass is crucial. Generally, the smooth side of the glass should face outwards to ensure light transmittance, while the rough side should face inwards to ensure a strong bond between the glass and the adhesive film layer. If the glass is reversed, it can easily lead to delamination and other failures in the photovoltaic modules, and significantly reduce their power output. Therefore, in the actual production of photovoltaic modules, it is essential to ensure accurate orientation of the glass at the loading end. Currently, photovoltaic module production lines lack dedicated facilities for inspecting the orientation of the glass; inspections are conducted manually on the incoming glass, making it impossible to check every piece of glass. This introduces the risk of missed inspections, and manual inspection is time-consuming, labor-intensive, increases costs, and impacts production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a glass front and back inspection device that can quickly determine the smooth and rough surfaces of glass, reduce labor costs, and improve production efficiency.

[0005] This application provides a glass front and back detection device for distinguishing between smooth and rough surfaces of glass, comprising:

[0006] A launching mechanism for launching a slider along the upper surface of the glass;

[0007] A receiving mechanism is disposed opposite to the transmitting mechanism, and the receiving mechanism is used to receive the slider that slides across the upper surface of the glass;

[0008] The determination mechanism is signal-connected to the transmitting mechanism and the receiving mechanism. The determination mechanism is used to obtain the time difference between the slider being launched from the transmitting mechanism and being received by the receiving mechanism, and to determine whether the upper surface of the glass is a smooth surface or a rough surface based on the time difference.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the launching mechanism includes;

[0011] A first housing has a transmission channel formed inside it, and one end of the transmission channel penetrates the first housing to form a transmission port, which faces the receiving mechanism.

[0012] A striking rod, movably disposed within the first housing, is used to strike the slider located in the firing channel, thereby enabling the slider to slide along the firing channel and be ejected from the firing port;

[0013] A drive assembly for driving the impact rod from an initial position to an impact position, so that the impact rod impacts the slider; and

[0014] A first elastic element is connected to the impact rod, and the first elastic element is used to reset the impact rod from the impact position to the initial position.

[0015] In one embodiment, the first housing is provided with a storage cavity for storing a plurality of the sliders, the storage cavity being connected to the launch channel, and a second elastic member being provided at the bottom of the storage cavity, the second elastic member being used to push the sliders in the storage cavity one by one into the launch channel.

[0016] In one embodiment, the glass front and back detection device further includes a stop block disposed inside the first housing. The stop block and the inner wall of the first housing enclose the emission channel. The stop block is disposed opposite to the outlet of the storage cavity. The stop block is used to block the slider so that the slider enters the emission channel one by one.

[0017] In one embodiment, the driving component includes:

[0018] The chuck pin is rotatably connected to the first housing.

[0019] A firing pin, one end of which is detachably connected to the locking pin, and the other end of which is connected to a third elastic element; and

[0020] A button is connected to the chuck pin. The button is used to drive the chuck pin to rotate so that the striking pin separates from the chuck pin. When the striking pin separates from the chuck pin, the striking pin can strike the striking rod under the drive of the third elastic element so that the striking rod moves from the initial position to the impact position.

[0021] In one embodiment, the glass front and back detection device further includes a reset mechanism disposed within the first housing, the reset mechanism being used to drive the striker to reset to the state of connection with the caliper pin.

[0022] In one embodiment, a piston channel communicating with the launch channel is further formed within the first housing, and the reset mechanism includes:

[0023] A piston rod, which is movably inserted into the piston channel and sealably fitted with the inner wall of the piston channel;

[0024] A movable block is connected to the piston rod, and a striking rod is disposed on the movable block. The movable block can move towards the striking pin under the drive of the piston rod, so as to drive the striking rod to collide with the striking pin and reset the striking pin to the state of being connected with the locking pin.

[0025] In one embodiment, the reset mechanism further includes a fourth elastic element connected to the movable block, the fourth elastic element being used to drive the movable block to move away from the firing pin.

[0026] In one embodiment, the receiving mechanism includes a second housing with a receiving channel for the slider to pass through. A positioning sensor is provided in the receiving channel, and the positioning sensor is used to send a positioning signal to the determination mechanism when the slider enters the receiving channel.

[0027] In one embodiment, the positioning sensor includes an infrared transmitter and an infrared receiver, which are respectively disposed on two opposite sidewalls within the receiving channel.

[0028] The aforementioned glass front and back detection device uses a launching mechanism to launch a slider along the upper surface of the glass, a receiving mechanism to receive the slider as it slides across the upper surface of the glass, and a judging mechanism to obtain the time difference between the slider's launch from the launching mechanism and its reception by the receiving mechanism, thus determining the time required for the slider to slide across the upper surface of the glass. Since the surface friction coefficient of a smooth surface of glass is less than that of a rough surface, the time required for the slider to slide across a smooth surface is less than the time required to slide across a rough surface. Therefore, by obtaining the time required for the slider to slide across the upper surface of the glass through the judging mechanism, it is possible to quickly determine whether the upper surface of the glass is smooth or rough. Compared to traditional manual methods, the glass front and back detection device of this application can automatically distinguish between smooth and rough surfaces of glass, saving labor costs, improving production efficiency, preventing reversed glass from entering the subsequent photovoltaic module production process, and improving the yield of photovoltaic module production.

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0042] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] One embodiment of this application provides a glass front and back detection device for distinguishing the smooth and rough surfaces of glass 40. The glass 40 can be a glass backplate or glass cover for photovoltaic module encapsulation, or other glass 40 that simultaneously has smooth and rough surfaces. Understandably, the smooth surface of glass 40 refers to the surface of glass 40 that is smooth, has good light transmittance, and a low coefficient of friction. The smooth surface of glass 40 also refers to the surface of glass 40 that has undergone frosting or has a rough texture; rough surfaces have reflective and refractive effects on light, have a high coefficient of friction, and can increase the peel strength with the adhesive film.

[0044] See Figure 1 One embodiment of the glass front and back detection device includes a transmitting mechanism 10, a receiving mechanism 20, and a judging mechanism 50. The transmitting mechanism 10 is used to transmit a slider 30 along the upper surface of the glass 40. The receiving mechanism 20 is disposed opposite to the transmitting mechanism 10 and is used to receive the slider 30 that slides across the upper surface of the glass 40. The judging mechanism 50 is signal-connected to the transmitting mechanism 10 and the receiving mechanism 20. The judging mechanism 50 is used to obtain the time difference between the slider 50 being emitted from the transmitting mechanism 10 and being received by the receiving mechanism 20, and to judge whether the upper surface of the glass 40 is a smooth surface or a rough surface based on the time difference.

[0045] For example, the determining mechanism 50 is pre-defined with a first time interval including the time required for the slider 30 to slide across the smooth surface of the glass 40 and a second time interval including the time required for the slider 30 to slide across the rough surface of the glass 40. The maximum value of the second time interval is less than the minimum value of the first time interval. The determining mechanism 50 is used to obtain the time difference between the slider 30 being launched from the launching mechanism 10 and being received by the receiving mechanism 20. When the time difference falls within the first time interval, the determining mechanism 50 determines the upper surface of the glass 40 as a smooth surface; when the time difference falls within the second time interval, the determining mechanism 50 determines the upper surface of the glass 40 as a rough surface. Optionally, the first time interval is a range of values ​​obtained from multiple tests for the time required for the slider 30 to slide across the smooth surface of the glass 40. Similarly, the second time interval is a range of values ​​obtained from multiple tests for the time required for the slider 30 to slide across the rough surface of the glass 40. Furthermore, the first time interval and the second time interval can be pre-stored in the storage module of the determination mechanism 50. When needed, they can be directly called by the processor of the determination mechanism 50. Alternatively, they can be manually input into the determination mechanism 50 by the worker as parameters before each work session. There are no restrictions on this.

[0046] Specifically, the aforementioned glass front and back detection device can be applied in a glass feeding mechanism. During operation, when the glass 40 moves to the detection station located between the transmitting mechanism 10 and the receiving mechanism 20, the transmitting mechanism 10 transmits the slider 30 along the upper surface of the glass 40. After the slider 30 slides across the upper surface of the glass 40, it is received by the receiving mechanism 20. At the same time, the determination mechanism 50 records the time when the transmitting mechanism 10 transmits the slider 30 and the time when the receiving mechanism 20 receives the slider 30 and calculates the time difference between the two, thereby obtaining the time required for the slider 30 to slide across the upper surface of the glass 40.

[0047] Since the surface friction coefficient of the smooth surface of glass 40 is less than that of the rough surface, according to the friction force calculation formula F=μN, the friction force experienced by the slider 30 of the same mass sliding on the smooth surface is greater than that experienced on the rough surface. Therefore, when the launching mechanism 10 launches the slider 30 with a constant force, according to Newton's second law, the acceleration of the slider 30 sliding on the smooth surface is greater than that of the slider 30 sliding on the rough surface. Therefore, the time required for the slider 30 to slide across the smooth surface is less than the time required for the slider 30 to slide across the rough surface. Therefore, by obtaining the time required for the slider 30 to slide across the upper surface of glass 40 through the determining mechanism 50, it is possible to determine whether the upper surface of glass 40 is a smooth surface or a rough surface.

[0048] Specifically, a first time interval containing the time required for the slider 30 to slide over the smooth surface of the glass 40 and a second time interval containing the time required for the slider 30 to slide over the rough surface of the glass 40 can be pre-input into the judging mechanism 50. When the time required for the slider 30 to slide over the upper surface of the glass 40 falls within the first time interval, the upper surface of the glass 40 can be judged as a smooth surface; when the time required for the slider 30 to slide over the upper surface of the glass 40 falls within the second time interval, the upper surface of the glass 40 is judged as a rough surface. In this way, the smooth and rough surfaces of the glass 40 can be distinguished, and it can be determined whether the front and back of the glass 40 are placed accurately. When the front and back of the glass 40 are placed accurately, the glass feeding mechanism allows the glass 40 to flow into the next process. When the front and back of the glass 40 are reversed, the glass feeding mechanism rejects the reversed glass 40, thereby preventing the reversed glass 40 from flowing into subsequent processes.

[0049] The aforementioned glass front and back detection device uses a launching mechanism 10 to launch a slider 30 along the upper surface of the glass 40, a receiving mechanism 20 to receive the slider 30 as it slides across the upper surface of the glass 40, and a determining mechanism 50 to obtain the time difference between the time the slider 30 is launched from the launching mechanism 10 and the time it is received by the receiving mechanism 20. This allows the determination of the time required for the slider 30 to slide across the upper surface of the glass 40. Since the surface friction coefficient of the smooth surface of the glass 40 is less than that of the rough surface, the time required for the slider 30 to slide across the smooth surface is less than the time required to slide across the rough surface. Therefore, by obtaining the time required for the slider 30 to slide across the upper surface of the glass 40 through the determining mechanism 50, and comparing it with a first time interval (containing the time required for the slider 30 to slide across the smooth surface of the glass 40) and a second time interval (containing the time required for the slider 30 to slide across the rough surface of the glass 40) pre-stored in the determining mechanism 50, it is possible to quickly determine whether the upper surface of the glass 40 is smooth or rough. Compared to traditional manual identification methods, the glass front and back detection device of this application can automatically distinguish between the smooth and rough surfaces of the glass 40, saving labor costs, improving production efficiency, preventing the glass 40 with its front and back reversed from flowing into the subsequent photovoltaic module production process, and improving the production yield of photovoltaic modules.

[0050] Combination Figure 2In one embodiment, the launching mechanism 10 includes a first housing 11, a striking rod 131, a driving assembly 133, and a first elastic member 132. A launching channel 111 is formed within the first housing 11, with one end of the channel penetrating through the housing to form a launching port 112, which faces the receiving mechanism 20. The striking rod 131 is movably disposed within the first housing 11 and is used to strike a slider 30 located in the launching channel 111, allowing the slider 30 to slide along the channel 111 and exit from the launching port 112. The driving assembly 133 drives the striking rod 131 from an initial position to an impact position, causing the striking rod 131 to strike the slider 30. The first elastic member 132 is connected to the striking rod 131 and is used to reset the striking rod 131 from the impact position to the initial position.

[0051] Specifically, when the slider 30 needs to be launched, the drive assembly 133 applies an impact force to the impact rod 131, causing the impact rod 131 to move from its initial position to the impact position, so that the impact rod 131 strikes the slider 30 located in the launch channel 111. The slider 30 can then slide along the launch channel 111 and be launched from the launch port 112. After the impact rod 131 strikes the slider 30, it can return to its initial position under the elastic force of the first elastic element 132, waiting for the next impact on the slider 30.

[0052] Optionally, in one embodiment, the first housing 11 is provided with a storage cavity 113 for storing multiple sliders 30. The storage cavity 113 is connected to the launch channel 111. A second elastic member 121 is provided at the bottom of the storage cavity 113. The second elastic member 121 is used to push the sliders 30 in the storage cavity 113 one by one into the launch channel 111. Specifically, multiple sliders 30 are stacked in the storage cavity 113. When the impact rod 131 pushes the top slider 30 out of the launch channel 111, the second elastic member 121 immediately pushes the next slider 30 into the launch channel 111 to wait for the impact rod 131 to strike. This realizes the automatic supply of sliders 30, ensuring that the front and back sides of the glass 40 on the production line can be continuously inspected in sequence, thus improving efficiency.

[0053] See also Figure 2 In one embodiment, the glass front and back detection device further includes a stop 15, which is disposed inside the first housing 11. The stop 15 and the inner wall of the first housing 11 enclose an emission channel 111. The stop 15 is disposed opposite to the outlet of the storage cavity 113. The stop 15 is used to block the sliders 30 so that the sliders 30 enter the emission channel 111 one by one. Specifically, the vertical distance from the stop 15 to the outlet of the storage cavity 113 is equal to the thickness of one slider 30, thereby ensuring that the second elastic member 121 can only push one slider 30 into the emission channel 111 at a time.

[0054] See Figure 2Optionally, in one embodiment, the driving assembly 133 includes a locking pin 1332, a striking pin 1333, and a button 1331. The locking pin 1332 is rotatably connected to the first housing 11. One end of the striking pin 1333 is detachably connected to the locking pin 1332, and the other end of the striking pin 1333 is connected to a third elastic element 1334. The button 1331 is connected to the locking pin 1332 and is used to drive the locking pin 1332 to rotate, so that the striking pin 1333 separates from the locking pin 1332. When the striking pin 1333 separates from the locking pin 1332, the striking pin 1333 can strike the striking rod 131 under the drive of the third elastic element 1334, so that the striking rod 131 moves from the initial position to the impact position.

[0055] Specifically, the locking pin 1332 can engage with one end of the firing pin 1333. The third elastic element 1334 can be a torsion spring, which stores elastic potential energy when the firing pin 1333 and the locking pin 1332 are engaged. When the slider 30 needs to be launched, pressing the button 1331 can rotate the locking pin 1332. The rotation of the locking pin 1332 will release the engagement between the locking pin 1332 and the firing pin 1333, causing the firing pin 1333 to separate from the locking pin 1332. Then, the third elastic element 1334 releases its elastic potential energy to drive the firing pin 1333 to strike the striking rod 131, thereby causing the striking rod 131 to strike the slider 30, ultimately launching the slider 30. For example, pressing the button 1331 will trigger an electrical signal, thereby triggering the determination mechanism 50 to obtain the time when the launching mechanism 10 launches the slider 30.

[0056] It should be noted that in other embodiments, the drive component 133 may also be an electric actuator or other electrical drive component, as long as it can apply a constant impact force to the impact rod 131, and there is no limitation here.

[0057] Optionally, in one embodiment, the glass front and back detection device further includes a reset mechanism 14, which is disposed in the first housing 11. The reset mechanism 14 is used to drive the striker 1333 to reset to the state connected with the locking pin 1332, thereby ensuring that the striker 1333 can strike the striker 131 in the next launch slider 30.

[0058] Specifically, see Figure 2 In one embodiment, a piston channel 114 communicating with the launch channel 111 is also formed inside the first housing 11. The reset mechanism 14 includes a piston rod 141 and a movable block 142. The piston rod 141 is movably inserted in the piston channel 114 and is sealed to the inner wall of the piston channel 114. The movable block 142 is connected to the piston rod 141. The impact rod 131 is disposed on the movable block 142. The movable block 142 can move towards the impact pin 1333 under the drive of the piston rod 141, so as to drive the impact rod 131 to collide with the impact pin 1333, so that the impact pin 1333 is reset to the state of being connected to the locking pin 1332.

[0059] Specifically, when the striker 131 strikes the slider 30, the slider 30 generates heat and compresses the air inside the launch channel 111 as it slides along the launch channel 111. The compressed air enters the piston channel 114 and impacts the piston rod 141, causing the piston rod 141 to move backward, thereby driving the movable block 142 towards the direction of the striker 1333. Figure 2 The moving block 142 moves to the left and then drives the impact rod 131 to collide with the impact pin 1333, thereby resetting the impact pin 1333 to the state of being connected with the locking pin 1332.

[0060] Furthermore, based on the above embodiments, the reset mechanism 14 further includes a fourth elastic element 143, which is connected to the movable block 142. The fourth elastic element 143 is used to drive the movable block 142 in a direction away from the striker 1333. Figure 2 The piston rod 141 moves to the right (from center), thereby resetting the movable block 142 and piston rod 141 to their initial positions. At this time, the impact rod 131 re-engages with the slider 30, ensuring that the impact rod 131 can stably impact the slider 30 when the slider 30 is launched next time.

[0061] See Figure 3 Optionally, in one embodiment, the receiving mechanism 20 includes a second housing 21, which is provided with a receiving channel 211 for the slider 30 to pass through. A positioning sensor is provided in the receiving channel 211, which is used to send a positioning signal to the determination mechanism 50 when the slider 30 enters the receiving channel 211.

[0062] Specifically, when the slider 30 enters the receiving channel 211, the position sensor is triggered and sends a position signal. After the determination mechanism 50 receives the position signal, it can obtain the time when the slider 30 reaches the receiving mechanism 20, and thus obtain the time when the slider 30 slides across the upper surface of the glass 40.

[0063] See Figure 3 The positioning sensor includes an infrared transmitter 22 and an infrared receiver 23, which are respectively disposed on two opposite side walls within the receiving channel 211. Specifically, the infrared transmitter 22 is used to emit infrared light, and the infrared receiver 23 is used to receive infrared light. When the slider 30 enters the receiving channel 211, the infrared light is blocked by the slider 30, preventing the infrared receiver 23 from receiving the infrared light. The electrical signal of the infrared receiver 23 changes, and the infrared receiver 23 then sends a positioning signal to the determination mechanism 50.

[0064] Optionally, in one embodiment, the determination mechanism 50 can be a device with a processor, such as a computer, mobile phone, or server, that can store and process data; there is no limitation on this.

[0065] Optionally, in one embodiment, the slider 30 is a component with a small mass and a low coefficient of friction. The shape of the slider 30 can be square, circular, or other shapes, etc., and there is no limitation.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
