Description

Technical Field

[0001] This utility model relates to the field of display panel manufacturing technology, and in particular to a display panel transfer device. Background Technology

[0002] During the manufacturing process of display panel 200', a transfer device 100' is needed to temporarily hold display panel 200' so that it can wait to enter the next workstation. For example, Figure 1 As shown, the transfer device 100' typically includes a transfer box 1', which has a receiving cavity 11' and an inlet 110' communicating with the receiving cavity 11' on its outer periphery. The bottom of the receiving cavity 11' has a supporting structure 12' for supporting the display panel 200'. It should be noted that the "display panel 200'" mentioned above can refer to either a finished display panel 200' that has been manufactured, or a semi-finished display panel 200' that has not yet completed all manufacturing processes.

[0003] However, during the transfer of the display panel 200' on the production line, it may be damaged at the edges due to collisions with manufacturing and transportation equipment. Even if such a display panel 200' enters the next workstation from the transfer equipment 100 to continue the subsequent manufacturing steps, it will ultimately only result in a defective product that needs to be discarded, resulting in a waste of manufacturing materials and time. Utility Model Content

[0004] The purpose of this invention is to provide a transfer device for display panels, which has the function of detecting the edge damage of the supported display panels, so that display panels with edge breakage defects can be discarded in advance during the transfer process, thereby reducing the waste of manufacturing materials and time.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A relay device for a display panel is provided, comprising:

[0007] A transfer box, having a receiving cavity, has an inlet / outlet communicating with the receiving cavity on its outer periphery. The bottom of the receiving cavity has a supporting structure for supporting the non-edge portion of a display panel. The bottom wall of the transfer box also has a through groove located on the outer periphery of the supporting structure. A light-transmitting plate is sealed within the through groove, positioned directly below the edge portion of the display panel.

[0008] An edge detection device includes a signal transmitter and a signal receiver arranged at intervals opposite to each other. One of the signal transmitter and the signal receiver is located at the top of the accommodating cavity and facing the light-transmitting plate, while the other is located on the side of the light-transmitting plate away from the accommodating cavity. The signal receiver is used to receive electromagnetic wave signals emitted by the signal transmitter.

[0009] As a preferred embodiment of the transfer device for the display panel, the upper surface of the light-transmitting plate is flush with the bottom wall of the accommodating cavity, or the upper surface of the light-transmitting plate protrudes from the bottom wall of the accommodating cavity.

[0010] As a preferred embodiment of the transfer device for the display panel, the light-transmitting plate is located within the through groove and spaced apart from the opening of the through groove. The light-transmitting plate divides the through groove into a recess and an outer cavity. The recess communicates with the receiving cavity, and the outer cavity is located on the side of the light-transmitting plate opposite to the receiving cavity.

[0011] The bottom of the transfer box is also provided with an air inlet channel and an air outlet channel connecting the groove and the external space of the transfer box. The two ends of the groove along its own length are respectively connected to the air inlet channel and the air outlet channel. The air inlet channel is used to connect to the blower.

[0012] The transfer device also includes a drive unit and a cover. The drive unit is connected between the transfer box and the cover, and the drive unit can drive the cover to close onto or move away from the groove.

[0013] As a preferred embodiment of the transfer device for the display panel, the groove is provided with an air inlet channel and an air outlet channel at both ends along its length.

[0014] As a preferred embodiment of the transfer device for the display panel, the outer periphery of the supporting structure is provided with grooves on multiple sides, and the multiple grooves are connected to form a strip groove. The two ends of the strip groove are respectively provided with the air inlet channel and the air outlet channel, and the two ends of the strip groove are respectively connected to the air inlet channel and the air outlet channel.

[0015] As a preferred embodiment of the transfer device for the display panel, the four sides of the outer periphery of the supporting structure are respectively provided with the grooves, the four grooves are connected to form an annular groove surrounding the supporting structure, and the air inlet channel is connected at the connection of two of the grooves, and the air outlet channel is connected at the connection of the other two grooves.

[0016] As a preferred embodiment of the transfer device for the display panel, the transfer box is provided with the through slot on at least two opposite sides of the supporting structure, one near the entrance and one far from the entrance.

[0017] As a preferred embodiment of the relay device for the display panel, the edge detection device further includes a strip track, which is disposed in the relay box corresponding to the light-transmitting plate. The signal transmitter is movably disposed on the strip track, and the signal receiver has a long strip structure, the length direction of which is consistent with the length direction of the corresponding light-transmitting plate.

[0018] As a preferred embodiment of the relay device for the display panel, the strip track is located at the top of the receiving cavity, and the signal receiver is located on the side of the light-transmitting plate opposite to the receiving cavity; or,

[0019] The strip track is located on the side of the light-transmitting plate opposite to the receiving cavity, and the signal receiver is located on the top of the receiving cavity.

[0020] As a preferred embodiment of the relay device for the display panel, the relay device further includes a dust cover, which is disposed on the side of the light-transmitting plate opposite to the receiving cavity, and the signal transmitter or the signal receiver is disposed between the dust cover and the light-transmitting plate.

[0021] The advantages of this utility model compared to the prior art are:

[0022] The present invention relates to a transfer device for display panels. By setting an edge detection device on the outer periphery of a supporting structure, the signal transmitter included in the edge detection device can emit electromagnetic wave signals toward the edge of the display panel supported by the supporting structure. When the edge of the display panel is damaged, the electromagnetic wave signal emitted by the signal transmitter can be conducted to the signal receiver through the gap space at the damaged point. Therefore, when the electromagnetic wave signal received by the signal receiver suddenly increases, it can be determined that the edge of the display panel is damaged. Thus, the transfer device can detect the damage to the edge of the supported display panel through the edge detection device, so that display panels with edge breakage defects can be discarded in advance during the transfer process, thereby reducing the waste of manufacturing materials and time.

[0023] When the display panel is placed on and off the supporting structure, some impurities may fall to the bottom of the receiving cavity during the process. Alternatively, external impurities may enter the receiving cavity through the inlet / outlet of the display panel and fall to the bottom. Therefore, when the signal transmitter or receiver is located at the bottom of the receiving cavity, after a period of use, impurities may fall directly onto the signal transmitter (facing upwards) or the signal receiver (facing upwards). To address this, a through-slot is provided on the outer periphery of the supporting structure to allow electromagnetic wave signals to propagate. A light-transmitting plate is placed within the through-slot, directly facing the edge of the display panel supported by the supporting structure. This prevents the light-transmitting plate from interfering with the propagation of electromagnetic waves between the signal transmitter and receiver. Furthermore, the light-transmitting plate also shields the signal transmitter or receiver located on the side facing outwards from the receiving cavity, preventing impurities from falling directly onto the signal transmitter or receiver. Understandably, when impurities fall onto the light-transmitting plate, the plate's surface is relatively flat and its surface area is large. Therefore, impurities are unlikely to remain in one place on the plate. Instead, they are more likely to move with the airflow or even detach from the plate. This design reduces the possibility of impurities remaining in positions that could affect the transmitter's signal transmission or the receiver's signal reception, thus improving the stability of the relay equipment's detection function for edge damage to the supported display panel.

[0045] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0046] The present invention will now be described in detail with reference to the accompanying drawings.

[0047] like Figure 2 and Figure 3 As shown, a transfer device 100 for a display panel 200 is provided, including a transfer box 1 and an edge detection device 2. The transfer box 1 has a receiving cavity 11, and an inlet 110 communicating with the receiving cavity 11 is provided on the outer periphery of the transfer box 1. A supporting structure 12 is provided at the bottom of the receiving cavity 11. The supporting structure 12 is used to support the non-edge part of the display panel 200. The bottom wall of the transfer box 1 is also provided with a through groove 13 located on the outer periphery of the supporting structure 12. A light-transmitting plate 14 is sealed in the through groove 13. The light-transmitting plate 14 is positioned directly below the edge part of the display panel 200. The edge detection device 2 includes a signal transmitter 21 and a signal receiver 22 arranged at intervals and opposite to each other. One of the signal transmitter 21 and the signal receiver 22 is located at the top of the receiving cavity 11 and facing the light-transmitting plate 14, and the other is located on the side of the light-transmitting plate 14 away from the receiving cavity 11. The signal receiver 22 is used to receive electromagnetic wave signals emitted by the signal transmitter 21.

[0048] By setting an edge detection device 2 on the outer periphery of the support structure 12, the signal transmitter 21 included in the edge detection device 2 can emit electromagnetic wave signals toward the edge portion of the display panel 200 supported by the support structure 12. When the edge portion of the display panel 200 is damaged, the electromagnetic wave signal emitted by the signal transmitter 21 can be conducted to the signal receiver 22 through the gap space at the damaged point. Therefore, when the electromagnetic wave signal received by the signal receiver 22 suddenly increases, it can be determined that the edge portion of the display panel 200 is damaged. Thus, the transfer equipment 100 can realize the function of detecting the damage to the edge of the supported display panel 200 through the edge detection device 2, so that the display panel 200 with edge breakage defects can be discarded in advance during the transfer process, thereby reducing the waste of manufacturing materials and time.

[0049] When the display panel 200 is placed on the support structure 12, some impurities may fall to the bottom of the accommodating cavity 11 during the placement and removal process. Alternatively, external impurities may enter the accommodating cavity 11 through the inlet / outlet 110 of the display panel 200 and fall to the bottom of the accommodating cavity 11. Therefore, when the signal transmitter 21 or the signal receiver 22 is located at the bottom of the accommodating cavity 11, after a period of use, impurities may fall directly to the signal transmitting end of the signal transmitter 21 facing upwards or the signal receiving end of the signal receiver 22 facing upwards. Therefore, by providing a through groove 13 on the outer periphery of the support structure 12, electromagnetic wave signals can pass through the through groove 13 for propagation. Furthermore, a light-transmitting plate 14 is provided in the through groove 13 so that the light-transmitting plate 14 is directly opposite the edge of the display panel 200 supported by the support structure 12. This can prevent the light-transmitting plate 14 from affecting the propagation of electromagnetic waves between the signal transmitter 21 and the signal receiver 22. On the other hand, the light-transmitting plate 14 can also shield the signal transmitter 21 or the signal receiver 22 located on the side of the light-transmitting plate 14 away from the receiving cavity 11, so as to prevent impurities from falling directly onto the signal transmitting end of the signal transmitter 21 facing upward or the signal receiving end of the signal receiver 22 facing upward. Understandably, when impurities fall onto the light-transmitting plate 14, the surface of the light-transmitting plate 14 is relatively flat, and the plate surface of the light-transmitting plate 14 is relatively large. Therefore, impurities are not likely to stay in one place on the light-transmitting plate 14. Instead, they are likely to move in position with the airflow or even detach from the plate surface of the light-transmitting plate 14. Therefore, this setting can reduce the possibility that impurities will stay in a position that will affect the signal transmitter 21 to transmit signals or affect the signal receiver 22 to receive signals, so that the relay equipment 100 has better stability in detecting the damage to the edge of the supported display panel 200.

[0050] Understandably, the terms "top" and "bottom" mentioned above refer to the top and bottom along the direction of gravity when the transfer equipment 100 is in its working position. Furthermore, the terms "up" and "down" in this text also refer to the up and down positions along the direction of gravity when the transfer equipment 100 is in its working position. Figures 1 to 4 The coordinates show the upper and lower positions of the transfer device 100 along the direction of gravity when it is in the working posture.

[0051] In addition, the signal transmitter 21 or signal receiver 22 located on the side of the light-transmitting plate 14 away from the receiving cavity 11 can be entirely located inside the through groove 13, or partially located inside the through groove 13 with the rest located outside the through groove 13, or can be entirely located outside the through groove 13.

[0052] Optionally, the upper surface of the light-transmitting plate 14 may be flush with the bottom wall of the receiving cavity 11, or the upper surface of the light-transmitting plate 14 may protrude from the bottom wall of the receiving cavity 11. Thus, impurities falling onto the light-transmitting plate 14 are more likely to move with the airflow and detach from the light-transmitting plate 14. In particular, when the upper surface of the light-transmitting plate 14 protrudes from the bottom wall of the receiving cavity 11, since impurities are more likely to move to a lower position along the direction of gravity when moving with the airflow, impurities are more likely to move from the upper surface of the light-transmitting plate 14 to the bottom wall of the receiving cavity 11. In other words, the upper surface of the light-transmitting plate 14 is more likely to be kept in a state with fewer or even no impurities.

[0053] Please combine Figures 4 to 6 As shown, in other embodiments, the upper surface of the light-transmitting plate 14 may be lower than the bottom wall of the accommodating cavity 11. In this case, optionally, the light-transmitting plate 14 is located in the through groove 13 and spaced apart from the opening of the through groove 13. The light-transmitting plate 14 divides the through groove 13 into a recess 130 and an outer cavity 131. The recess 130 connects to the accommodating cavity 11, and the outer cavity 131 is located on the side of the light-transmitting plate 14 away from the accommodating cavity 11. The bottom of the transfer box 1 is also provided with an air inlet channel 15 and an air outlet channel 16 connecting the recess 130 and the external space of the transfer box 1. The two ends of the recess 130 along its own length direction are respectively connected to the air inlet channel 15 and the air outlet channel 16. The air inlet channel 15 is used to connect to a blower (not shown in the figure). The transfer device 100 also includes a driving member 3 and a cover 4. The driving member 3 is connected between the transfer box 1 and the cover 4. The driving component 3 can drive the cover 4 to close onto or move away from the groove 130. When the edge detection device 2 is working, the cover 4 can be positioned away from the groove 130 so that the groove 130 is connected to the receiving cavity 11. The cover 4 will not obstruct the signal emitted by the signal transmitter 21 from reaching the signal receiver 22. When the edge detection device 2 stops operating, the driving component 3 can drive the cover 4 to close onto the groove 130 and start the blower so that the airflow is blown into the groove 130 from the air inlet channel 15 and flows into the air outlet channel 16 in the groove 130. This will cause impurities in the groove 130 to be discharged from the air outlet channel 16, thereby achieving automatic cleaning of the inner wall of the groove 130 (including the upper surface of the light-transmitting plate 14) so ​​that the upper surface of the light-transmitting plate 14 can be kept in a relatively clean state.

[0054] The blower can be part of the transfer equipment 100 or an external blower. In addition, the blower can be directly connected to the air inlet channel 15, and the blower can be located entirely outside the air inlet channel 15 or partially inside the air inlet channel 15. Alternatively, the blower can be located outside the transfer equipment 100 and connected to the air inlet channel 15 through an air supply pipe.

[0055] The air inlet channel 15 and the air outlet channel 16 can be separated from the accommodating cavity 11, or the air inlet channel 15 and the air outlet channel 16 can be directly connected to the accommodating cavity 11. When the cover 4 is closed on the groove 130, the cover 4 can also be closed on the air inlet channel 15 and the air outlet channel 16 at the same time, so as to separate the air inlet channel 15 and the air outlet channel 16 from the accommodating cavity 11.

[0056] Optionally, the air inlet channel 15 may be provided with a filter (not shown in the figure) to filter impurities carried in the air entering the air inlet channel 15, so as to avoid secondary contamination of the inner wall of the groove 130 by external impurities.

[0057] It is understandable that the groove 130, the air inlet channel 15, and the air outlet channel 16 can have a variety of different specific configurations. Next, we will introduce several specific structures of the groove 130, the air inlet channel 15, and the air outlet channel 16 with reference to the attached drawings.

[0058] Please continue to see [the relevant documents / references]. Figure 5 and Figure 6 In one optional embodiment, each end of the groove 130 along its length is provided with an air inlet channel 15 and an air outlet channel 16, so that each groove 130 can receive air from the air inlet channel 15 at one end and exhaust air and remove impurities from the air outlet channel 16 at the other end, thereby achieving automatic cleaning of the groove 130. It can be understood that when the transfer box 1 has only one groove 130, each end of the groove 130 along its length is provided with an air inlet channel 15 and an air outlet channel 16; when the transfer box 1 has multiple grooves 130, each groove 130 along its length is provided with an air inlet channel 15 and an air outlet channel 16 at both ends.

[0059] like Figure 7 and Figure 8 As shown, in another optional embodiment, the outer periphery of the bearing structure 12 is provided with grooves 130 on multiple sides, and multiple grooves 130 are connected in sequence to form a strip groove (not labeled in the figure). The two ends of the strip groove are respectively provided with an air inlet channel 15 and an air outlet channel 16, and the two ends of the strip groove are respectively connected to the air inlet channel 15 and the air outlet channel 16. Thus, multiple grooves 130 can share the same air inlet channel 15 and air outlet channel 16, making the structure of the transfer box 1 simpler and more compact. All grooves 130 can get air in through the air inlet channel 15 at one end of the strip groove and exhaust and remove impurities from the air outlet channel 16 at the other end, so as to achieve automatic cleaning of all grooves 130.

[0060] Among them, such as Figure 7 As shown, the two grooves 130 located on adjacent sides of the load-bearing structure 12 can extend directly to be connected, as... Figure 8As shown, when the transfer box 1 has two grooves 130 on two opposite sides of the outer periphery of the bearing structure 12, an additional connecting groove 17 can be provided in the transfer box 1 to connect the ends of the two grooves 130.

[0061] like Figure 9 As shown, in another optional embodiment, the four sides of the outer periphery of the bearing structure 12 are respectively provided with grooves 130. The four grooves 130 are connected to form an annular groove (not labeled in the figure) surrounding the bearing structure 12. The connection between two of the grooves 130 is connected to an air inlet channel 15, and the connection between the other two grooves 130 is connected to an air outlet channel 16. Thus, the airflow input from the air inlet channel 15 can flow to the two grooves 130 connected to the air inlet channel 15, and then to the two grooves 130 connected to the air outlet channel 16, and finally to the air outlet channel 16, so as to drive the impurities in the four grooves 130 to flow out from the air outlet channel 16.

[0062] Optionally, the outer cavities 131 located on different sides of the bearing structure 12 can be separated from each other by the structure of the transfer box 1, or extended to be connected. In this case, the light-transmitting plate 14 can also be extended to the point where the two outer cavities 131 are connected, so that the point where the two outer cavities 131 are connected is separated from the point where the two grooves 130 are connected.

[0063] Since the display panel 200 is usually transported along a fixed front-to-back direction, in other words, when the display panel 200 is transported along the transport track, only two opposite sides of the display panel 200 are in the front-to-back direction of transport. During the transport process, the side of the display panel 200 that is forward along the transport direction is more likely to collide with other external structures and be damaged. Therefore, the two opposite sides of the display panel 200 along the front-to-back direction of transport are more likely to break. Furthermore, the direction in which the inlet / outlet 110 of the transfer box 1 faces is also the transport direction of the display panel 200. Thus, when the display panel 200 is placed on the support structure 12, the display panel 200 is closer to the inlet / outlet 110 and further away from the outlet / outlet 110. Since the two opposite sides of the entrance 110 are easily broken, the transfer box 1 may optionally have through slots 13 on at least the two opposite sides of the supporting structure 12 near the entrance 110 and away from the entrance 110. Thus, the edge detection device 2 can detect the damage of the display panel 200 on the supporting structure 12 near the entrance 110 and away from the entrance 110 respectively, corresponding to the two through slots 13. In other words, the edge detection device 2 can detect the edges of the display panel 200 that are more prone to breakage, so that the transfer equipment 100 can detect the breakage of the display panel 200 with higher accuracy, and at the same time make the structure of the transfer equipment 100 simpler.

[0064] The transfer box 1 may have only one inlet / outlet 110, or it may have multiple inlets / outlets 110. When the transfer box 1 has two inlets / outlets 110, the two inlets / outlets 110 may be located on opposite sides of the transfer box 1. In this case, the relative directions of the two inlets / outlets 110 are the transport directions when the display panel 200 is placed on the supporting structure 12. When the two inlets / outlets 110 are located on adjacent sides of the transfer box 1, all four sides of the display panel 200 may be in the forward / backward direction of transport when it is transported along the transport track. Therefore, in this case, the transfer box 1 may have through slots 13 on the four sides of the supporting structure 12, both near and away from the two inlets / outlets 110.

[0065] Furthermore, when the transfer box 1 has more than two entrances 110, usually at least two entrances 110 are located on adjacent sides of the transfer box 1. Therefore, when the display panel 200 is transported along the transport track, all four sides of the display panel 200 may be in the forward and backward direction of being transported, so that the transfer box 1 can be provided with through slots 13 on all four sides of the outer periphery of the bearing structure 12.

[0066] Please see again Figure 2 In order to detect the edge of the display panel 200, the signal transmitter 21 can be a long strip structure extending along the length direction of the through groove 13, or the signal transmitter 21 can be movably arranged along the length direction of the through groove 13, so that the signal transmitter 21 can transmit electromagnetic wave signals to various positions along the length direction of the through groove 13. At the same time, the signal receiver 22 can be a long strip structure extending along the length direction of the through groove 13, or the signal receiver 22 can be movably arranged along the length direction of the through groove 13, so that the signal transmitter 21 can receive electromagnetic wave signals emitted from various positions along the length direction of the through groove 13. In other words, both the signal transmitter 21 and the signal receiver 22 can be elongated structures extending along the length of the through groove 13, or the signal transmitter 21 can be elongated structures extending along the length of the through groove 13 and the signal receiver 22 can be movably arranged along the length of the through groove 13, or the signal transmitter 21 can be movably arranged along the length of the through groove 13 and the signal receiver 22 can be elongated structures extending along the length of the through groove 13, or both the signal transmitter 21 and the signal receiver 22 can be movably arranged along the length of the through groove 13.

[0067] Since the more signal transmission positions the signal transmitter 21 has, the greater the energy consumption of the signal transmitter 21, it is preferable that the signal transmitter 21 can be movably arranged along the length direction of the through slot 13 so that the energy consumption of a single signal transmitter 21 is smaller.

[0068] Please combine Figure 10 and Figure 11As shown, optionally, the edge detection device 2 may also include a strip track 23, which is disposed in the transfer box 1 corresponding to the light-transmitting plate 14. The signal transmitter 21 is movably disposed on the strip track 23, so that the signal transmitter 21 can move along the length direction of the strip track 23. Furthermore, by aligning the length direction of the strip track 23 with the length direction of the through groove 13, the signal transmitter 21 can move along the length direction of the through groove 13.

[0069] Specifically, the signal transmitter 21 may also be connected to a drive mechanism 24 to drive the signal transmitter 21 to move along the length of the strip track 23. For example, the signal transmitter 21 and the transfer box 1 may be connected by a drive mechanism 24 capable of outputting linear motion, such as, but not limited to, a cylinder, a linear motor, or a lead screw motor. Alternatively, the strip track 23 or the transfer box 1 may be provided with a rack 25 arranged along the length of the strip track 23, and the signal transmitter 21 may be provided with a drive mechanism 24 capable of outputting rotational motion. The drive mechanism 24 is connected to a gear 26 meshing with the rack 25. The drive mechanism 24 may include, but is not limited to, a rotary motor or a rotary cylinder. The drive mechanism 24 can drive the gear 26 to rotate, thereby moving the signal transmitter 21 along the length of the strip track 23.

[0070] In one alternative example, the strip track 23 is located at the top of the accommodating cavity 11, the signal transmitter 21 is located at the top of the accommodating cavity 11 along with the strip track 23, and the signal receiver 22 is located on the side of the light-transmitting plate 14 away from the accommodating cavity 11.

[0071] In another alternative example, the strip track 23 is disposed on the side of the light-transmitting plate 14 away from the receiving cavity 11, the signal transmitter 21 is disposed outside the receiving cavity 11 along the strip track 23, and the signal receiver 22 is disposed on the top of the receiving cavity 11. Thus, the signal transmitter 21, the strip track 23, and the drive mechanism 24 for driving the signal transmitter 21 to move along the length direction of the strip track 23 can be disposed outside the receiving cavity 11 to avoid impurities adhering to these complex structures such as the strip track 23 and the drive mechanism 24 inside the receiving cavity 11.

[0072] Since the receiving area of ​​the signal receiver 22 has a relatively small impact on the energy consumption and material cost of the relay equipment 100, the signal receiver 22 can optionally be a long strip structure with the length direction of the signal receiver 22 consistent with the length direction of the corresponding light-transmitting plate 14, thereby avoiding the need for further setting of tracks, drives and other components, so that the structure of the edge detection device 2 is simpler and the control difficulty is lower.

[0073] It is understandable that when the signal receiver 22 is movable along the length of the through slot 13, its specific setting method can be referred to the setting method of the signal transmitter 21 being movable along the length of the through slot 13 mentioned above, and will not be repeated here.

[0074] Please see again Figure 3 and Figure 4 Optionally, the transfer device 100 also includes a dust cover 5, which is installed on the side of the light-transmitting plate 14 away from the receiving cavity 11. A signal transmitter 21 or a signal receiver 22 is provided between the dust cover 5 and the light-transmitting plate 14, so that dust and other impurities can be blocked from contacting the signal transmitter 21 or the signal receiver 22 located outside the receiving cavity 11 through the dust cover 5, so as to further avoid impurities affecting the detection accuracy of the edge detection device 2.

[0075] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
