Turnover device and dispensing system

Abstract

The invention discloses a turnover device and a dispensing system, and belongs to the technical field of terminals. The turnover device comprises a base, a first bearing part and a second bearing part. Before the shell and the screen enter the dispensing process, the turnover device can bear the shell and the screen. Due to the fact that the first bearing piece in the turnover device bears the shell, and after the second bearing piece in the turnover device is located at the first position and bears the screen, a gap is formed between the screen and the shell, the screen cannot be bonded with the gum located on the third bonding edge of the shell, and therefore it is guaranteed that in the follow-up shell glue dispensing process, the glue dispensing efficiency is improved. And the screen does not shield the first bonding edge and the second bonding edge of the shell, so that the dispensing equipment can normally dispense glue on the first bonding edge and the second bonding edge of the shell.

Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a turnover device and a dispensing system. Background Art

[0002] With the development of terminal technology, terminal devices are becoming thinner and lighter. In order to make the thickness of terminal devices smaller, the flip chip process is usually used to assemble terminal devices. The flip chip process is to first assemble the internal accessories of the terminal device into the shell, and then assemble the screen and the shell. When assembling the screen and the shell, it is necessary to connect the screen with the middle frame in the shell.

[0003] Before the screen is connected to the middle frame, the screen and the internal accessories must be connected through the cable. Due to the existence of the cable, the adjustment range of the relative position relationship between the screen and the middle frame is limited. At present, in the process of connecting the screen and the middle frame, in order to ensure that the connection between the cable and the internal accessories and the screen will not loosen, the screen and the middle frame are generally assembled using a back adhesive process.

[0004] However, in the process of assembling the screen and the middle frame using the adhesive backing process, in order to ensure the connection strength between the screen and the middle frame, a larger bonding position needs to be left on the middle frame, resulting in a wider border of the terminal device, and in turn resulting in a smaller screen-to-body ratio of the terminal device. Summary of the invention

[0041] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0042] In the present application, in the process of assembling the terminal device using the flip-chip process, in order to ensure a high connection strength between the screen and the shell in the terminal device without increasing the border width of the terminal device, a combination of back glue and spot glue can be used to connect the screen and the shell.

[0043] For details, please refer to Figure 1 , Figure 1 010 is a top view of a shell provided by an embodiment of the present application, and the shell 010 may have a first bonding edge A1 and a second bonding edge A2 that are relatively arranged in the second direction Y, and two third bonding edges A3 that are relatively arranged in the first direction X. Here, the length of the third bonding edge A3 may be less than the length of the first bonding edge A1 and the length of the second bonding edge A1. The two third bonding edges A3 of the shell 010 may be formed with adhesive backing on the two third bonding edges A3 respectively using an adhesive backing process. The shell 010 with adhesive backing may enter a subsequent adhesive dispensing process, so as to dispense adhesive on the first adhesive edge A1 and the second adhesive edge A2 of the shell 010 respectively through an adhesive dispensing device to form a first adhesive strip and a second adhesive strip.

[0044] The embodiment of the present application provides a turnover device, which can be used to carry the housing 010 and the screen 020. The turnover device carrying the housing 010 and the screen 020 can enter the subsequent dispensing process. Figure 2 and Figure 3 , Figure 2 is a schematic diagram of the structure of a turnover device provided in an embodiment of the present application, Figure 3 It is a structural schematic diagram of a turnover device carrying a screen and a shell provided in an embodiment of the present application. The turnover device 000 may include: a base 100, a first bearing member 200 and a second bearing member 300.

[0045] The first bearing member 200 in the bearing device can be fixed on the base 100 , and the first bearing member 200 can be used to bear the housing 010 for mounting functional components.

[0046] The second carrier 300 in the carrier device can be slidably connected to the base 100, and the second carrier 300 can slide to a first position and a second position relative to the base 100. After the second carrier 300 is located at the first position, at least a portion of the second carrier 300 can be located on a side of the first carrier 200 away from the base 100. And after the second carrier 300 is located at the first position, the second carrier 300 can be used to carry the screen 020. Here, the screen 020 can be connected to the functional components installed in the housing 010 through a cable. And there can be a gap between the screen 020 and the housing 010.

[0047] After the second carrier 300 is located at the second position, the orthographic projection of the second carrier 300 on the base 100 does not overlap with the orthographic projection of the first carrier 200 on the base 100. In this way, after the turnover device 000 carries the housing 010 and the screen 020 to enter the glue dispensing process, during the glue dispensing process of the housing 010, the second carrier 300 in the second position will not block the housing 010 located on the first carrier 200, so that the glue dispensing device can normally dispense glue on the housing 010.

[0048] In the present application, before the shell 010 and the screen 020 enter the glue dispensing process, the turnover device 000 can carry the shell 010 and the screen 020. Since the first carrier 200 in the turnover device 000 carries the shell 010, and after the second carrier 300 in the turnover device 000 is located at the first position and carries the screen 020, there is a gap between the screen 020 and the shell 010, so the screen 020 will not be bonded to the back glue located on the third bonding edge A3 of the shell 010, thereby ensuring that in the subsequent process of glue dispensing on the shell 010, the screen will not block the first bonding edge A1 and the second bonding edge A2 of the shell 010, so that the glue dispensing equipment can normally dispense glue on the first bonding edge A1 and the second bonding edge A3 of the shell 010.

[0049] In summary, an embodiment of the present application provides a turnover device, including: a base, a first carrier and a second carrier. Before the shell and the screen enter the dispensing process, the turnover device can carry the shell and the screen. Since the first carrier in the turnover device carries the shell, and after the second carrier in the turnover device is located at the first position and carries the screen, there is a gap between the screen and the shell, so the screen will not be bonded to the back glue located on the third bonding edge of the shell, thereby ensuring that in the subsequent process of dispensing the shell, the screen will not block the first bonding edge and the second bonding edge of the shell, so that the dispensing equipment can normally dispense glue on the first bonding edge and the second bonding edge of the shell.

[0050] Optional, please refer to Figure 4 , Figure 4: is a schematic diagram of the structure of another turnover device provided by an embodiment of the present application. The second carrier 300 in the turnover device 000 may include: two groups of sub-carriers 300a. The two groups of sub-carriers 300a in the second carrier 300 may be arranged at both ends of the base 100 in the first direction X, and both groups of sub-carriers 300a may be slidably connected to the base 100. In the first direction X, after the two groups of sub-carriers 300a move in a direction away from each other, the second carrier 300 may move from the first position to the second position. After the two groups of sub-carriers 300a move in a direction close to each other, the second carrier 300 may move from the second position to the first position.

[0051] Optional, such as Figure 4 As shown, each group of sub-carriers 300a in the second carrier 200 may include: at least two sub-carrier bodies 301, and a sliding portion 302 connected to the at least two sub-carrier bodies 301. The at least two sub-carrier bodies 301 in each group of sub-carriers 300a may be arranged in a row in the second direction Y, and the sliding portion 302 in each group of sub-carriers 300a may be slidably connected to the base 100, and the sliding direction of the sliding portion 302 relative to the base 100 may be parallel to the first direction X. Here, the first direction X may intersect with the second direction Y, and for example, the first direction X may intersect with the second direction Y perpendicularly. And both the first direction X and the second direction Y may be parallel to the base 100.

[0052] In this way, the sliding part 302 in each group of sub-carriers 300a can drive at least two sub-carrier bodies 301 to slide relative to the base 100 along the first direction X. It should be noted that the number of sliding parts 302 in each group of sub-carriers 300a can be one, that is, one sliding part 302 can simultaneously drive at least two sub-carrier bodies 301 to slide relative to the base 100 along the first direction X. Alternatively, the number of sliding parts 302 in each group of sub-carriers 300a is multiple, and the multiple sliding parts 302 can be connected to at least two sub-carrier bodies 301 in a one-to-one correspondence. Each sub-carrier body 301 can slide relative to the base 100 along the first direction X driven by the corresponding sliding part 302, and at least two sub-carrier bodies 301 in each group of sub-carriers 300a can simultaneously slide relative to the base 100 along the first direction X driven by the corresponding sliding part 302.

[0053] For example, each group of sub-carriers 300a in the second carrier 300 may include two sub-carrier bodies 301, and the two sub-carrier bodies 301 may be arranged in a row along the second direction Y. In this way, the second carrier 300 may have four sub-carrier bodies 301. After the second carrier 300 is located at the first position, the four sub-carrier bodies 301 in the second carrier 300 may respectively support the four corners of the screen 020, so that the second carrier 300 can carry the screen 020.

[0054] It should be noted that the sliding part 302 in each group of sub-carriers 300a may include a first sliding member, and the side of the base 100 facing the second carrier 300 may include a second sliding member that cooperates with the first sliding member, and the first sliding member may slide relative to the second sliding member. For example, the first sliding member may be one of a sliding protrusion or a sliding track, and the second sliding member may be the other of the sliding protrusion or the sliding track.

[0055] Optional, such as Figure 4 As shown, the first carrier 200 may have a bearing groove K for bearing the housing 010, and in a direction perpendicular to the base 100, the depth of the bearing groove K may be less than or equal to the thickness of the housing 010. Here, after the second carrier 300 is located at the second position, the orthographic projection of the second carrier 300 on the base 100 does not overlap with the orthographic projection of the bearing groove K of the first carrier 200 on the base 100.

[0056] The side of the second carrier 300 facing away from the base 100 is a bearing surface P for bearing the screen. The distance between the side of the second carrier 300 opposite to the bearing surface P and the base 100 may be greater than the distance between the side of the first carrier 200 facing away from the base 100 and the base 100. This ensures that after the housing 010 is carried in the bearing groove K of the first carrier 200 and the screen 020 is carried on the bearing surface P of the second carrier 300, there is a gap between the screen 020 and the housing 010.

[0057] In summary, an embodiment of the present application provides a turnover device, including: a base, a first carrier and a second carrier. Before the shell and the screen enter the dispensing process, the turnover device can carry the shell and the screen. Since the first carrier in the turnover device carries the shell, and after the second carrier in the turnover device is located at the first position and carries the screen, there is a gap between the screen and the shell, so the screen will not be bonded to the back glue located on the third bonding edge of the shell, thereby ensuring that in the subsequent process of dispensing the shell, the screen will not block the first bonding edge and the second bonding edge of the shell, so that the dispensing equipment can normally dispense glue on the first bonding edge and the second bonding edge of the shell.

[0058] The embodiment of the present application further provides a glue dispensing system, comprising: a glue dispensing device 400, a suction device 500 and a turnover device 000, and the turnover device 000 is the turnover device 000 in the above embodiment.

[0059] The turnover device 000 in the dispensing system can carry the housing 010 and the functional components installed in the housing 010 through the first carrier 200, and the turnover device 000 can carry the screen 020 through the second carrier 300 in the first position. Here, the screen 020 can be connected to the functional components installed in the housing 010 through a cable.

[0060] It should be noted that in the housing 010 carried by the turnover device 000 in the glue dispensing system, both third bonding edges A3 of the housing 010 have adhesive backing formed by the adhesive backing process. There is a gap between the screen 020 on the second carrier 300 in the turnover device 000 and the housing 010 on the first carrier 200 in the turnover device 000, so that the screen 020 will not be bonded to the adhesive backing.

[0061] The glue dispensing device in the glue dispensing system is configured to dispense glue to the housing 010 after the screen 020 located on the second carrier 300 is sucked by the suction device 500 and the second carrier 020 is in the second position.

[0062] Please note that, please refer to Figure 5 and Figure 6 , Figure 5 is a partial top view of a dispensing system provided in an embodiment of the present application, Figure 6 It is a structural schematic diagram of a local structure in a dispensing system provided by an embodiment of the present application. The dispensing device 400 may have a dispensing position 400a. After the turnover device 000 is located at the dispensing position 400a on the dispensing device 400, the suction device 500 may suck the screen 020 located on the second carrier 300, so that the second carrier 300 will no longer carry the screen 020. Then, the second carrier 300 may be moved from the first position to the second position, so that the second carrier 300 will not cover the housing 010 located on the first carrier 200. In this way, after the second carrier 300 is in the second position, the dispensing device 400 can dispense glue to the housing 010.

[0063] It should be noted that the dispensing system may further include a lower lifting and opening mechanism. The lower lifting and opening structure in the dispensing system can drive the second carrier 300 to move from the first position to the second position after the suction device 500 sucks the screen 020 to separate the screen 020 from the second carrier 300.

[0064] Optionally, the first bonding edge A1 and the second bonding edge A2 in the shell 010 on the turnover device 000 need to be glued.

[0065] After the suction device 500 sucks the screen 020, it can drive the screen 020 to move to the third position or the fourth position. Figure 7 As shown, Figure 7 It is a partial top view of a glue dispensing system provided by an embodiment of the present application when the screen is in the third position, and the orthographic projection of the screen 020 on the base 100 does not overlap with the orthographic projection of the first bonding edge A1 of the housing 010 on the base 100. That is, when the screen 020 is in the third position, the screen 020 will not block the first bonding edge A1 of the housing 010. In this way, the glue dispensing device 400 can dispense glue to the first bonding edge A1 after the screen 020 is in the third position to form a first glue strip on the first bonding edge A1.

[0066] It should be noted that, in the direction perpendicular to the base 100, the distance between the screen 020 in the third position and the screen 020 on the second carrier 300 may be 10 mm. In the second direction Y, the distance between the side of the screen 020 in the third position corresponding to the first bonding edge A1 and the side of the screen 020 on the second carrier 300 corresponding to the first bonding edge A1 may be 20 mm. In this way, after the screen 020 is in the third position, the orthographic projection of the screen 020 on the base 100 does not overlap with the orthographic projection of the first bonding edge A1 of the housing 010 on the base 100.

[0067] After the screen 020 is in the fourth position, as Figure 8 As shown, Figure 8 1 is a partial top view of a glue dispensing system provided by an embodiment of the present application when the screen is in the fourth position, and the orthographic projection of the screen 020 on the base 100 does not overlap with the orthographic projection of the second bonding edge A2 of the housing 010 on the base 100. That is, when the screen 020 is in the fourth position, the screen 020 will not block the second bonding edge A2 of the housing 010. In this way, the glue dispensing device 400 can dispense glue to the second bonding edge A2 after the screen 020 is in the fourth position to form a second glue strip on the second bonding edge A2.

[0068] It should be noted that, in the direction perpendicular to the base 100, the distance between the screen 020 in the fourth position and the screen 020 on the second carrier 300 may be 10 mm. In the second direction Y, the distance between the side of the screen 020 in the fourth position corresponding to the first bonding edge A2 and the side of the screen 020 on the second carrier 300 corresponding to the second bonding edge A2 may be 20 mm. In this way, after the screen 020 is in the fourth position, the orthographic projection of the screen 020 on the base 100 does not overlap with the orthographic projection of the second bonding edge A2 of the housing 010 on the base 100.

[0069] Optionally, the suction device in the glue dispensing system can also stop sucking the screen 020 after forming a first glue strip on the first bonding edge A1, or forming a second glue strip on the second bonding edge A2, so that the screen 020 is re-positioned on the second carrier 300 in the first position.

[0070] Here, after forming the first adhesive strip on the first adhesive edge A1 or forming the second adhesive strip on the second adhesive edge A2, the lower lifting and opening mechanism in the dispensing system can drive the second carrier 300 to move from the second position to the first position. Then, the suction device 500 in the dispensing system can put the screen 020 on the second carrier 300 again, and stop sucking the screen 020 after the screen 020 is on the second carrier 300.

[0071] Optional, please refer to Fig. 9 , Fig. 9 4 is a top view of a dispensing system provided in an embodiment of the present application. The number of dispensing devices in the dispensing system can be two, and the two dispensing devices are respectively a first dispensing device 401 and a second dispensing device 402. The number of suction devices in the dispensing system is also two, and the two suction devices are respectively a first suction device and a second suction device.

[0072] The dispensing system may further include: a transmission device 600. The first dispensing device 401 and the first suction device in the dispensing system may be correspondingly arranged on the first section 601 of the transmission device 600, and the second dispensing device 402 and the second suction device in the dispensing system may be correspondingly arranged on the second section 602 of the transmission device 600.

[0073] The glue dispensing system can, after driving the turnover device 000 to move to the first section 601 through the transmission device 600, absorb the screen 020 through the first suction device and drive the screen 020 to move to the third position. After the second carrier 300 is in the second position, the glue dispensing system can dispense glue to the first bonding edge A1 of the shell 010 through the first glue dispensing device 401 to form a first glue strip.

[0074] It should be noted that the glue dispensing system may also include two lower lifting mechanisms, which are respectively arranged corresponding to the first glue dispensing device 401 and the second glue dispensing device 402. After the turnover device moves to the first section 601 through the transmission device 600, the turnover device can be located at the glue dispensing position of the first glue dispensing device 401. Then the first suction device can absorb the screen 020 and drive the screen 020 to move to the third position. Then a lower lifting mechanism arranged corresponding to the first glue dispensing device 401 can drive the second carrier 300 to move from the first position to the second position. After the second carrier 300 moves to the second position, the first glue dispensing device 401 can dispense glue to the first bonding edge A1 to form a first glue strip.

[0075] After the first adhesive strip is formed, the first adhesive dispensing device 401 can stop dispensing adhesive to the first bonding edge A1. The lower lifting mechanism can drive the second carrier 300 to move from the second position to the first position, and after the second carrier 300 is in the first position, the first suction device can stop sucking the screen 020, so that the screen 020 can be re-positioned on the second carrier 300 in the first position. In this case, there is a certain gap between the screen 020 and the housing 010 having the first adhesive strip and the two second adhesive strips, so that the screen 020 will not be bonded to the first adhesive strip and the backing adhesive.

[0076] After the first adhesive strip is formed and the turnover device is re-loaded with the screen 020, the transmission device 600 can drive the turnover device 000 to move to the second section 602, and after the turnover device moves to the second section 602, the turnover device can be located at the dispensing position of the second dispensing device 402. Then the second suction can absorb the screen 020 and drive the screen 020 to move to the fourth position. Then a lower lifting mechanism corresponding to the second dispensing device 402 can drive the second carrier 300 to move from the first position to the second position. After the second carrier 300 moves to the second position, the second dispensing device can dispense glue to the second bonding edge A2 to form a second adhesive strip.

[0077] After the second adhesive strip is formed, the second adhesive dispensing device 402 can stop dispensing adhesive to the second bonding edge A2. The lower lifting mechanism can drive the second carrier 300 to move from the second position to the first position, and after the second carrier 300 moves to the first position, the second suction device can stop sucking the screen 020, so that the screen 020 can be relocated on the second carrier 300 in the first position. In this case, there can be a certain gap between the screen 020 and the housing 010 having the first adhesive strip, the second adhesive strip and the adhesive backing.

[0078] Optional, such as Fig. 9As shown, the glue dispensing system may further include: a screen attaching device 700. The screen attaching device 700 in the glue dispensing system may be configured to attach the housing 010 and the screen 020 after forming a first glue strip on the first adhesive edge A1 and a second glue strip on the second adhesive edge A2.

[0079] It should be noted that if Fig. 9 As shown, after the first adhesive strip and the second adhesive strip are formed, the transmission device 600 can drive the turnover device 000 to move to the third section 603, and after the turnover device moves to the third section 603, the turnover device can be located in the screen attaching device 700. Here, after the first adhesive strip and the second adhesive strip are formed, there is still a certain gap between the screen 020 and the shell 010 located on the turnover device, so as to ensure that before the turnover device is transmitted to the screen attaching device 700, the screen 020 will not be bonded to the first adhesive strip, the second adhesive strip and the backing adhesive on the shell 010, thereby ensuring the accuracy of the subsequent screen attaching device 700 to attach the shell 010 and the screen 020.

[0080] In this application, if Figure 5 and Figure 6 As shown, the dispensing system may further include: an upper lifting mechanism 800, and the turnover device carrying the housing 010 and the screen 020 may be manually placed on the upper lifting mechanism 800. Here, the upper lifting mechanism 800 may have a pin, and the base 100 of the turnover device may have a pin hole, and the carrying position of the turnover device on the upper lifting mechanism 800 may be determined by the cooperation between the pin and the pin hole.

[0081] After the upper lifting mechanism 800 carries the turnover device 000, the upper lifting mechanism 800 can deliver the turnover device to the fourth section 604 of the transmission device 600. Here, the fourth section 604 of the transmission device 600 is located at the end of the first section 601 away from the second section 602. In this way, the turnover device can be located on the fourth section of the transmission device 600. It should be noted that the dispensing system can also include: a material induction fixture, and the dispensing system can obtain that the fourth section 604 of the transmission device 600 has carried the turnover device 000 through the material induction fixture.

[0082] Next, the transmission device 600 can transmit the turnover device 000 to the first section 601, so that the turnover device 000 can be located at the dispensing position 400a of the first dispensing device 401. It should be noted that the dispensing system also includes: a side clamping mechanism and a clamping sensor. After the turnover device 000 is located in the first section 601 of the transmission device 600, the dispensing system can adjust the position of the turnover device 000 through the side clamping mechanism, so that the position of the turnover device 000 at the dispensing position 400a is accurate, and then in the subsequent dispensing process, the dispensing position can be guaranteed to be accurate. After the position of the turnover device 000 is accurately adjusted, the dispensing system can obtain through the side clamping sensor that the turnover device 000 has been adjusted.

[0083] Next, the first suction device can suck the screen 020 to drive the screen 020 to move to the third position. Here, the first suction device can first drive the screen 020 to move 10 mm in a direction away from the second carrier 300, and then drive the screen 020 to move 20 mm in a direction away from the first bonding edge A1, so that the screen 020 is in the third position.

[0084] Next, the glue dispensing system can identify the position of the first bonding edge A1 of the shell 010, so as to dispense glue on the first bonding edge A1 through the first glue dispensing device 401. Here, the glue dispensing system can also include: a 2D camera, and the shell 010 can also have a marking point. The glue dispensing system can obtain an image including the shell 010 through the 2D camera, and then obtain the position of the first bonding edge A1 through the marking point on the image.

[0085] Next, after the glue dispensing system dispenses glue on the first bonding edge A1 through the first glue dispensing device 401 to form the first glue strip, the glue dispensing system also needs to perform quality inspection on the first glue strip. The quality inspection process can be performed before the first suction device puts the screen 020 back on the second carrier 300. The glue dispensing system can also include: a 3D camera, and the glue dispensing system can detect the first glue strip through the image of the housing 010 with the first glue strip taken by the 3D camera to determine whether the first glue strip is qualified.

[0086] It should be noted that after the dispensing system performs quality inspection on the first adhesive strip, no matter whether the first adhesive strip is qualified or not, the screen 020 needs to be re-placed on the second carrier 300 by the first suction device.

[0087] Next, the transport device 600 can transport the turnover device 000 to the fifth section 605. Here, the fifth section 605 of the transport device 600 can be located between the second section 602 and the third section 603, that is, between the dispensing position 400a of the first dispensing device 401 and the dispensing position 400a of the second dispensing device 402. The dispensing system can also include an NG blocking cylinder corresponding to the fifth section 605.

[0088] When the first glue strip is unqualified, the dispensing system can control the NG blocking cylinder to rise to block the turnover device to prevent the turnover device with the unqualified first glue strip from flowing into the second dispensing device. When the first glue strip is qualified, the dispensing system can control the NG blocking cylinder to descend so that the transmission device 600 can transmit the turnover device to the third section 603.

[0089] And when the first rubber strip is unqualified, the dispensing system can sound an alarm to remind the worker to remove the turnover device blocked by the NG blocking cylinder, so that the turnover device carrying the qualified first rubber strip can pass through the fifth section 605 normally to reach the third section 603.

[0090] It should be noted that after the turnover device enters the third section 603, the process of the dispensing system forming the second glue strip on the second bonding edge A2 through the second dispensing device 402 is the same as the process of forming the first glue strip on the first bonding edge A1 through the first dispensing device 401, and will not be repeated here.

[0091] In this application, if Figure 5 and Figure 6 As shown, one dispensing device can have two dispensing positions at the same time, so that one dispensing device can dispense glue to two shells at the same time, which makes the production efficiency of the dispensing device higher.

[0092] In the present application, the dispensing system may also include a vacuum suction cup. Fig.10 As shown, Fig.10 It is a back view of a turnover device improved by an embodiment of the present application. The base 100 of the turnover device may have a vacuum opening V, and the vacuum opening V may be connected to the bearing groove K of the first bearing member 200, so that when the bearing groove K carries the shell 010, the shell 010 may have a portion exposed through the vacuum opening V.

[0093] Before the glue dispensing system sucks the screen 020 through the suction device, the vacuum suction cup in the glue dispensing system can contact the shell 010 through the vacuum opening on the base 100, so that the shell 010 can be firmly fixed in the supporting groove to prevent the shell 010 from falling off from the supporting groove K when the suction device drives the screen 020 to move to the third position or the fourth position.

[0094] It should be noted that if Fig.10 As shown, the base 100 of the turnover device may have a plurality of through holes H. By providing a plurality of through holes H, the overall weight of the turnover device can be reduced, so that the transmission device 600 can transmit the turnover device with only a small force.

[0095] It should also be noted that after the screen 020 and the housing 010 are bonded together by the screen bonding device 700, the bonded screen 020 and the housing 010 need to be placed in a pressure-maintaining box for pressure maintenance to improve the reliability of the connection between the screen 020 and the housing 010. Here, the bonded screen 020 and the housing 010 can be left in the pressure-maintaining box for two hours.

[0096] It should be noted that in the accompanying drawings, the sizes of layers and regions may be exaggerated for clarity of illustration. It is also understood that when an element or layer is referred to as being "on" another element or layer, it may be directly on the other element, or there may be an intermediate layer. In addition, it is understood that when an element or layer is referred to as being "under" another element or layer, it may be directly under the other element, or there may be more than one intermediate layer or element. In addition, it is also understood that when a layer or element is referred to as being "between" two layers or two elements, it may be the only layer between the two layers or two elements, or there may also be more than one intermediate layer or element. Similar reference numerals throughout the text indicate similar elements.

[0097] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.

[0098] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
