Abstract
Description
Technical Field
[0001] This invention relates to the field of display module technology, and in particular to a method, apparatus and equipment for bonding a metal plate to a carrier plate. Background Technology
[0002] In the manufacturing of display modules, to ensure the robustness of the display module, a metal plate is usually bonded to the glass substrate of the display module. Typically, a carrier plate is used to hold the metal plate to be bonded to the glass substrate, and then the metal plate is transported to the glass substrate for alignment and bonding.
[0003] Typically, a carrier plate has multiple bonding areas, each corresponding to an area on the glass substrate where a metal plate is bonded. This ensures accurate alignment and bonding when the carrier plate bonds the metal plate to the glass substrate. The bonding areas on the carrier plate usually have openings as markers to facilitate accurate bonding of the metal plate to the carrier plate before it is transferred to the glass substrate.
[0004] Due to the rapid updates in display devices, the specifications of display modules have also diversified. Consequently, the specifications of metal plates are constantly being updated to match the specifications of display modules, making it impossible for the marked carrier boards to be used for a long time. In addition, it is necessary to re-set the opening positions of the carrier boards according to the specifications of the display modules, which is costly and results in a significant waste of resources. Summary of the Invention
[0005] This invention provides a method, apparatus, and equipment for bonding a metal plate to a carrier plate, in order to solve the problems that the carrier plate cannot be used for a long time and that setting openings on the carrier plate is costly.

[0007] After the carrier plate is located in the operating area, the first position information of the carrier plate is acquired by the image acquisition device;
[0008] The second position information of the preset fitting area is determined based on the first position information;
[0009] The image acquisition device is controlled to move to the first target area according to the second position information; the vertical projection of the first target area on the carrier plate coincides with the preset bonding area.
[0010] The image acquisition device acquires the first image information of the metal plate.
[0011] Based on the first image information, determine whether the vertical projection of the metal plate on the carrier plate coincides with the preset bonding area;
[0012] If so, the metal plate is controlled to adhere to the preset adhesion area.
[0013] According to another aspect of the present invention, an apparatus for bonding a metal plate to a carrier plate is provided, the carrier plate including at least one predetermined bonding area for bonding the metal plate, comprising:
[0014] The first position information acquisition module is used to acquire the first position information of the carrier plate through an image acquisition device after the carrier plate is located in the operation area.
[0015] The second position information determination module is used to determine the second position information of the preset fitting area based on the first position information;
[0016] A first motion control module is used to control the image acquisition device to move to a first target area according to the second position information; the vertical projection of the first target area on the carrier plate coincides with the preset bonding area.
[0017] The first image information acquisition module is used to acquire first image information of the metal plate through the image acquisition device;
[0018] The overlap determination module is used to determine whether the vertical projection of the metal plate on the carrier plate overlaps with the second preset bonding area based on the first image information.
[0019] The bonding control module is used to control the metal plate to bond to the preset bonding area after the overlap judgment module determines, based on the first image information, that the vertical projection of the metal plate on the carrier plate overlaps with the second preset bonding area.
[0020] According to another aspect of the present invention, an apparatus for bonding a metal plate to a carrier plate is provided, comprising: a support stage, an image acquisition device, an image acquisition driving device, a metal plate driving device, and a controller.
[0021] The support platform is used to place the carrier plate;
[0022] The image acquisition device, the image acquisition driving device, and the metal plate driving device are all electrically connected to the controller;
[0023] The image acquisition device acquires image information of the metal plate and / or carrier plate under the control of the controller;

[0025] The metal plate driving device is used to adsorb the metal plate and drive the metal plate to move under the control of the controller;
[0026] The controller is used to perform the above-described method of attaching a metal plate to a carrier plate.
[0027] The method for bonding a metal plate to a carrier plate provided in this embodiment of the invention first places the carrier plate in the operation area when bonding the metal plate to the carrier plate. After the carrier plate is in the operation area, the first position information of the carrier plate is acquired by an image acquisition device. Combined with the position of the preset bonding area on the carrier plate, the second position information of the preset bonding area can be determined based on the first position information. Then, the image acquisition device is moved to a first target area that coincides with the preset bonding area in the vertical direction according to the second position information.

After determining that the vertical projection of the metal plate on the carrier plate coincides with the preset bonding area based on the first image information, the metal plate is controlled to be bonded to the preset bonding area. It is not necessary to achieve the alignment and bonding of the metal plate and the preset bonding area on the carrier plate according to the opening mark on the carrier plate, so that there is no need to set the opening on the carrier plate, which can effectively reduce the process cost. Furthermore, the carrier plate without openings can be divided into different bonding areas, which can effectively improve the utilization rate of the carrier plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0078] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0079] This invention provides a device for bonding a metal plate to a carrier plate. Figure 1 This is a schematic diagram of a device for bonding a metal plate to a carrier plate according to an embodiment of the present invention, as shown below. Figure 1 As shown, the device 10 for bonding a metal plate to a carrier plate includes: a support platform 14, an image acquisition device 11, an image acquisition driving device 12, a metal plate driving device 13, and a controller (not shown in the figure). The support platform 14 is used to place the carrier plate 20; the image acquisition device 11, the image acquisition driving device 12, and the metal plate driving device 13 are all electrically connected to the controller; the image acquisition device 11 acquires image information of the metal plate 30 and / or the carrier plate 20 under the control of the controller; the image acquisition driving device 12 drives the image acquisition device 11 to move under the control of the controller; the metal plate driving device 13 is used to adsorb the metal plate 30 and drives the metal plate 30 to move under the control of the controller. The controller is used for the method of bonding a metal plate to a carrier plate provided in any embodiment of the present invention. Therefore, the device for bonding a metal plate to a carrier plate provided in the embodiments of the present invention includes the technical features of the method of bonding a metal plate to a carrier plate provided in any embodiment of the present invention, and can achieve the beneficial effects of the method of bonding a metal plate to a carrier plate provided in any embodiment of the present invention. The specific technical features and technical effects are described in the following embodiments of the method of bonding a metal plate to a carrier plate.
[0080] Specifically, the support platform 14 can be fixed in a certain position, such as in the operating area A1, or it can move horizontally (i.e., within the XOY plane). The image acquisition device 11 can move under the drive of the image acquisition drive device 12, and preferably, the image acquisition device 11 can only move horizontally. It is understood that when the carrier plate 20 is placed on the support platform 14, the image acquisition device 11 should be located on the side of the carrier plate 20 away from the support platform 14, so as to facilitate the image acquisition device 11 to acquire image information of the carrier plate 20. The metal plate drive device 13 can be located on the side of the image acquisition device 11 away from the support platform 14, and can adsorb the metal plate 30, and when adsorbing the metal plate 30, the metal plate 30 faces the support platform 14. Based on this, the metal plate drive device 13 can drive the metal plate 30 to move horizontally or vertically (i.e., along the ZO or OZ direction) under the control of the controller.
[0081] Based on this, embodiments of the present invention provide a method for bonding a metal plate to a carrier plate, which is executed by the controller in the aforementioned device for bonding a metal plate to a carrier plate. This method can solve the problems of the carrier plate not being able to be used for a long time and the high cost of setting openings on the carrier plate. Alternatively, the method for bonding a metal plate to a carrier plate is executed by the device for bonding a metal plate to a carrier plate provided in the embodiments of the present invention, which can be integrated into the controller of the device for bonding a metal plate to a carrier plate provided in the embodiments of the present invention.
[0082] This invention provides a method for bonding a metal plate to a carrier plate. Figure 2 This is a flowchart of a method for bonding a metal plate to a carrier plate according to an embodiment of the present invention, as shown below. Figure 2 As shown, the method for bonding a metal plate to a carrier plate includes:
[0083] S110. After the carrier plate is located in the operating area, the first position information of the carrier plate is obtained through the image acquisition device.
[0084] Specifically, after the carrier plate 20 is located in the operation area A1, the image acquisition device 11 can be driven to move into the operation area A1, and then the image acquisition device 11 can be controlled to acquire the image information of the carrier plate 20, so as to determine the position information (i.e., the first position information) of the carrier plate based on the image information of the carrier plate 20.
[0085] S120. Determine the second position information of the preset fitting area based on the first position information.
[0086] Specifically, the carrier plate 20 may have multiple areas for bonding the metal plate 30, and the metal plate 30 can be sequentially bonded to areas of the same shape and size. That is, each time the operation of bonding the metal plate 30 to the carrier plate 20 is performed, the metal plate 30 has a corresponding preset bonding area A2. It can be understood that the positions of each preset bonding area A2 on the carrier plate 20 are preset according to the layout information of different production lines. Therefore, after obtaining the first position information of the carrier plate 20, combined with the position information of the preset bonding area A2 (e.g., preset bonding area A21) corresponding to the metal plate 30 on the carrier plate 20, the position information of the preset bonding area A21 (i.e., the second position information) can be determined based on the first position information of the carrier plate 20.
[0087] S130. Control the image acquisition device to move to the first target area according to the second position information.
[0088] The vertical projection of the first target area on the carrier plate 20 coincides with the preset bonding area A21.
[0089] Specifically, for ease of positioning and operation, the image acquisition device 11 can be configured to move horizontally. Within its reachable range, it can include a first target area, which is located directly above the preset bonding area A21, meaning its vertical projection on the carrier plate 20 coincides with the preset bonding area A21. Thus, the position information of the first target area can be determined based on the second position information, and the image acquisition device can be controlled to move to the first target area based on the second position information, thereby positioning the image acquisition device 11 directly above the preset bonding area A21.
[0090] S140. Acquire the first image information of the metal plate through the image acquisition device.
[0091] Specifically, the metal plate driving device 13 can move the metal plate 30 to a position approximately directly above the first target area, that is, to a position approximately directly above the preset bonding area A21, and the image acquisition device 11 can acquire the image information (i.e., the first image information) of the metal plate 30. The image acquisition device 11 can be configured to acquire image information bidirectionally, that is, it can acquire the image information of the carrier plate 20 located below it, and it can also acquire the image information of the metal plate 30 located above it.
[0092] S150. Determine whether the vertical projection of the metal plate on the carrier plate coincides with the preset bonding area based on the first image information; if so, proceed to step S160.
[0093] S160, Control the metal plate to adhere to the preset adhesion area.
[0094] Specifically, after acquiring the first image information, the image features of the metal plate 30 can be analyzed based on the first image information, and it can be determined whether the vertical projection of the metal plate 30 on the carrier plate 20 coincides with the preset bonding area A21. After determining that the vertical projection of the metal plate 30 on the carrier plate 20 coincides with the preset bonding area A21, the metal plate driving device 13 can be controlled to move vertically downward, that is, move along the ZO direction, so that the metal plate 30 can be accurately bonded to the preset bonding area A21. Before controlling the metal plate driving device 13 to move vertically downward, the image acquisition device can first be moved to a position that will not obstruct the progress of the metal plate driving device 13.
[0095] For example, if it is determined from the first image information that the vertical projection of the metal plate 30 on the carrier plate 20 does not coincide with the preset bonding area A21, the position of the metal plate 30 can be adjusted, that is, the metal plate driving device 13 is controlled to move, thereby adjusting the position of the metal plate 30. After adjusting the position, the first image information of the metal plate 30 is re-acquired through the image acquisition device 11, and the vertical projection of the metal plate 30 on the carrier plate 20 is again checked against the preset bonding area A21 based on the current first image information, until it is determined whether the vertical projection of the metal plate 30 on the carrier plate 20 coincides with the preset bonding area A21. Then, the adjustment of the position of the metal plate 30 is stopped, and the metal plate 30 is controlled to be bonded to the preset bonding area A21.
[0096] The method for bonding a metal plate to a carrier plate provided in this embodiment of the invention first places the carrier plate in the operation area when bonding the metal plate to the carrier plate. After the carrier plate is in the operation area, the first position information of the carrier plate is acquired by an image acquisition device. Combined with the position of the preset bonding area on the carrier plate, the second position information of the preset bonding area can be determined based on the first position information. Then, the image acquisition device is moved to a first target area that coincides with the preset bonding area in the vertical direction according to the second position information. At this time, the first image information of the metal plate is acquired by the image acquisition device. After determining that the vertical projection of the metal plate on the carrier plate coincides with the preset bonding area based on the first image information, the metal plate is controlled to be bonded to the preset bonding area. It is not necessary to achieve the alignment and bonding of the metal plate and the preset bonding area on the carrier plate according to the opening mark on the carrier plate, so that there is no need to set the opening on the carrier plate, which can effectively reduce the process cost. Furthermore, the carrier plate without openings can be divided into different bonding areas, which can effectively improve the utilization rate of the carrier plate.
[0097] Optional, see reference Figure 1 The image acquisition device 11 includes at least two coaxial camera modules 111, each coaxial camera module 111 including a higher camera C1 and a lower camera C2 set coaxially; the carrier plate 20 includes at least two first vertices a, and the first position information includes the first position coordinates of each first vertex a.
[0098] Specifically, the display module is generally rectangular in shape, meaning the mother plate, carrier plate, and metal plate are mostly rectangular. It is understood that the method for attaching a metal plate to a carrier plate provided in this embodiment of the invention is also applicable to other carrier plate shapes with at least two vertices or corners. The image acquisition device 11 may include at least two coaxial camera modules 111, specifically two, three, or four; this embodiment of the invention does not specifically limit this. For example, for a rectangular carrier plate 20, metal plate 30, and preset bonding area A21, only two coaxial camera modules are needed to achieve the technical solution of this invention. However, to improve the accuracy of alignment between the metal plate and the preset bonding area, the image acquisition device 11 may include three or four coaxial camera modules 111. Alternatively, for a carrier plate 20, metal plate 30, or preset bonding area A21 with more vertices, the image acquisition device 11 may include more coaxial camera modules 111 to achieve the technical solution of this invention; this embodiment of the invention does not specifically limit this. For ease of understanding, unless otherwise specified, the embodiments of the present invention are illustrated by taking the shape of the carrier plate 20, the metal plate 30 and the preset bonding area A21 as rectangles, and the image acquisition device 11 including two coaxial camera modules 111.
[0099] Specifically, the upper camera C1 and the lower camera C2 in the same coaxial camera module 111 are fixedly mounted at both ends of the connecting shaft L0. Along the extension direction of the connecting shaft L0, the upper camera C1 is located above the lower camera C2. The upper camera C1 is used to acquire image information from above (i.e., image information on one side of the connecting shaft L0 along the OZ direction), and the lower camera C2 is used to acquire image information from below (i.e., image information on one side of the connecting shaft L0 along the ZO direction).
[0100] Based on this Figure 3 This is a flowchart of another method for bonding a metal plate to a carrier plate according to an embodiment of the present invention, such as... Figure 3 As shown, the method for bonding a metal plate to a carrier plate includes:
[0101] S211. After the carrier plate is located in the operating area, control each coaxial camera module to move above different first vertices.
[0102] For details, please refer to Figure 1After the carrier plate 20 is positioned in the operating area A1, one of the coaxial camera modules 111 can be controlled to be positioned above one of the first vertices a of the carrier plate 20, and the other coaxial camera module 111 can be controlled to move above the other first vertices a. The two first vertices a can be two vertices located diagonally opposite each other, or vertices located at both ends of a long side of a rectangle, or vertices located at both ends of a short side of a rectangle; this embodiment of the invention does not specifically limit this. It is understood that if the image acquisition device 11 includes three coaxial camera modules 111, then the three coaxial camera modules 111 are respectively located above the three first vertices a; based on the same principle, if the image acquisition device 11 includes four coaxial camera modules 111, then the four coaxial camera modules 111 are respectively located above the four first vertices a.
[0103] S212, Control each lower-level camera to acquire the second image information of the carrier board.
[0104] Specifically, after moving each coaxial camera module 111 above a different first vertex a, the lower camera C2 in each coaxial camera module 11 is controlled to acquire image information (i.e., second image information) of the carrier plate 20.
[0105] S213. Determine whether each of the second image information includes the first vertex; if so, proceed to step S214.
[0106] S214. The horizontal coordinates of each coaxial camera module are determined as the first position coordinates of each first vertex.
[0107] Specifically, if each coaxial camera module 111 is located above a first vertex a, then after the lower camera C2 acquires the second image information of the carrier plate 20, each image information should include the corresponding first vertex a. Therefore, after acquiring the second image information of the carrier plate 20, it is determined whether each second image information includes the first vertex a. If it is determined that each second image information includes the first vertex a, then the current horizontal coordinates (XOY plane coordinates) of each coaxial camera module 111 can be correspondingly determined as the first position coordinates of each first vertex a. That is, after moving and aligning each coaxial camera module 111 directly above each first vertex a of the carrier plate 20, the actual placement position of the carrier plate 20 (the first position coordinates of each first vertex a) can be determined by the position coordinates of each coaxial camera module 111. In a preferred embodiment, when the center position of the second image information generated by the coaxial camera module 111 includes the first vertex a, the current horizontal coordinate (XOY plane coordinate) of each coaxial camera module 111 is determined as the first position coordinate of each first vertex a.
[0108] For example, if at least one of the second image information does not include the first vertex a, the position of the corresponding coaxial camera module 111 is adjusted until the second image information acquired by the coaxial camera module 111 includes the corresponding first vertex a, and the horizontal coordinate of the coaxial camera module 111 is determined as the first position coordinate of the first vertex a.
[0109] S215. Determine the second position information of the preset fitting area based on the first position information.
[0110] The preset fitting area A21 includes at least two first region vertices b, and the second position information includes the second position coordinates of each first region vertex b.
[0111] Specifically, taking a rectangle as an example of a preset fitting area A21, if the preset fitting area A21 includes at least two first region vertices b, then the two first region vertices b can be the vertices at both ends of the rectangle's diagonal, the vertices at both ends of one long side of the rectangle, or the vertices at both ends of one short side of the rectangle. Alternatively, the at least two first region vertices b can also be the four vertices of the rectangle.
[0112] S216. Based on the coordinates of each second position, control each coaxial camera module to move to different vertices of the second region of the first target area.
[0113] The first target region includes at least two second region vertices (not shown in the figure); the vertical projection of each second region vertex on the carrier plate 20 coincides with the corresponding first region vertex b.
[0114] Specifically, since the first target area coincides with the preset fitting area A21, it can be known that the shape and size of the first target area are the same as those of the preset fitting area A21, including the vertices at the same positions as those of the preset fitting area A21 (i.e., the vertices of the second area), and each of the vertices of the second area is located directly above the corresponding vertex b of the first area, that is, the vertical projection of each vertex of the second area on the carrier plate 20 coincides with the corresponding vertex b of the first area.
[0115] S217. Acquire the first image information of the metal plate through each upper-level camera.
[0116] Before the metal plate 30 is attached to the preset attachment area A21 of the carrier plate 20, the metal plate 30 is located on the side of the image acquisition device 11 away from the carrier plate 20.
[0117] Specifically, based on the setting of the coaxial camera module 111, before the metal plate 30 is attached to the preset attachment area A21 of the carrier plate 20, the metal plate 30 and the carrier plate 20 can be set to be located on the upper and lower sides of the image acquisition device 11, respectively. In this way, the coaxial camera module 111 can acquire the image information (i.e., the second image information) of the carrier plate 20 through the lower camera C2, and acquire the image information (first image information) of the metal plate 30 through the upper camera C1.
[0118] S218. Determine whether each of the first image information includes the second vertex of the metal plate; if yes, proceed to step S219; if no, proceed to step S221.
[0119] S219. Determine that the vertical projection of the metal plate on the carrier plate coincides with the preset bonding area.
[0120] S220, Control the metal plate to adhere to the preset adhesion area.
[0121] S221. Adjust the position of the metal plate; return to step S217.
[0122] Specifically, the metal plate 30 should be compatible with the preset bonding area A21, that is, they should have the same shape and size. Therefore, the metal plate 30 also includes at least two second vertices c corresponding to the preset bonding area A21. The first image information of the metal plate 30 can be obtained through each upper camera C1. Since each coaxial camera module 111 is located above different vertices of the preset bonding area A21, if the position of the metal plate 30 coincides with the preset bonding area A21 in the vertical direction, then each first image information should include the second vertex c at the corresponding position of the metal plate 30. Figure 4 This is a schematic diagram of another device for bonding a metal plate to a carrier plate according to an embodiment of the present invention, as shown below. Figure 4As shown, the metal plate 30 is located directly above the preset bonding area A21, meaning that the position of the metal plate 30 coincides with the preset bonding area A21 in the vertical direction. Therefore, when it is determined that each first image information should include the second vertex c at the corresponding position of the metal plate 30, it can be determined that the metal plate 30 is directly above the preset bonding area A21. At this time, the metal plate driving device 13 can be controlled to move vertically downward to bond the metal plate 30 to the preset bonding area A21 on the carrier plate 20. However, if at least one first image information does not include the second vertex c of the metal plate 30, it can be determined that the position of the metal plate 30 is offset relative to the preset bonding area A21. At this time, the position of the metal plate 30 is adjusted until it is determined that each first image information includes the second vertex c of the metal plate 30, and the position of the metal plate 30 is determined to be no offset relative to the preset bonding area A21. Then, the metal plate 30 can be controlled to bond to the preset bonding area A21. In a preferred embodiment, the coaxial camera module 111 is fixed, and the position of the metal plate 30 is adjusted so that the upper camera C1 can acquire different first image information. When it is determined that the center position of each first image information includes the second vertex c corresponding to the metal plate 30, it can be determined that the metal plate 30 is located directly above the preset bonding area A21.
[0123] Optional, Figure 5 This is a flowchart of another method for bonding a metal plate to a carrier plate according to an embodiment of the present invention, as shown below. Figure 5 As shown, the method for bonding a metal plate to a carrier plate includes:
[0124] S311. After the carrier plate is located in the operating area, the first position information of the carrier plate is obtained through the image acquisition device.
[0125] S312. Determine the second position information of the preset fitting area based on the first position information.
[0126] S313. Control the image acquisition device to move to the first target area according to the second position information.
[0127] The vertical projection of the first target area onto the carrier plate coincides with the preset bonding area.
[0128] S314. Acquire the first image information of the metal plate through the image acquisition device.
[0129] S315. Determine whether the vertical projection of the metal plate on the carrier plate coincides with the preset bonding area based on the first image information; if yes, proceed to step S317; if no, proceed to step S316.
[0130] S316. Adjust the position of the metal plate; return to step S314.
[0131] S317. Control the image acquisition device to move to the outside of the first target area.
[0132] S318, Control the metal plate to adhere to the preset adhesion area.
[0133] Specifically, after determining that the vertical projection of the metal plate 30 on the carrier plate 20 coincides with the preset bonding area A21, the image acquisition device 11 can be moved out of the first target area to avoid obstructing the process in the path of the metal plate 30 when controlling the metal plate 30 to be vertically and downwardly bonded to the preset bonding area A21 of the carrier plate 20. For example, Figure 6 This is a schematic diagram of another device for attaching a metal plate to a carrier plate provided by an embodiment of the present invention. As shown in Figure 6, each coaxial camera module 111 in the image acquisition device 11 can be controlled to move along the XO direction to the periphery of the carrier plate 20, so as to avoid obstruction when the coaxial camera module 111 is attached to the carrier plate 20.
[0134] S319. Control the image acquisition device to move back to the first target area.
[0135] S320: Obtain third image information of the preset bonding area through the image acquisition device.
[0136] S321. Detect the offset of the metal plate in the preset bonding area based on the third image information.
[0137] Specifically, after the metal plate 30 is attached to the preset attachment area A21 of the carrier plate 20, the image acquisition device can be controlled to return to the first target area. Figure 7 This is a schematic diagram of another device for bonding a metal plate to a carrier plate according to an embodiment of the present invention, as shown below. Figure 7 As shown, each coaxial camera module 111 can be controlled to return to directly above different vertices of the preset bonding area A21. Then, the lower camera C2 of each coaxial camera module 111 acquires image information (i.e., third image information) of the preset bonding area A21 on the carrier plate 20 again, so as to detect whether the bonding of the metal plate in the preset bonding area is offset according to the third image information.
[0138] For example, when detecting whether there is a misalignment in the bonding of the metal plate within the preset bonding area based on the third image information, it can be determined whether each third image information acquired by each lower camera C21 includes the second vertex c corresponding to the position of the metal plate 20. If it is determined that each third image information includes the second vertex c corresponding to the position of the metal plate 20, it can be determined that there is no misalignment in the bonding of the metal plate 20 on the carrier plate 20, and the same metal plate bonding method can be used to bond the metal plate in another bonding area A2 of the carrier plate 20. If at least one third image information does not include the second vertex c of the metal plate 20, it can be determined that there is a misalignment in the bonding of the metal plate 20 on the carrier plate 20, and the metal plate 20 can be removed and rebonded using the above method.
