[0002] With the development of terminal technology, terminal devices are increasingly thin and light. In order to make the thickness of the terminal device smaller, a flip process is usually used to assemble the terminal device. The flip process is to first assemble the internal components of the terminal device into the shell, and finally assemble the screen and the shell. When assembling the screen and the shell, the screen needs to be connected with the middle frame in the shell.

[0003] Currently, in order to ensure the connection strength between the screen and the middle frame, a dispensing process can be used to connect the screen and the middle frame. The dispensing process is to first dispense on the middle frame at the position where the screen needs to be connected, and then connect the screen to the middle frame by dispensing.

[0004] However, before the screen is connected with the middle frame, the screen needs to be connected with the internal components through a wire, and due to the existence of the wire, the adjustment range of the relative position relationship between the screen and the middle frame is limited, and thus the wire is prone to be detached from the screen or the internal components during the dispensing process.

[0033] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0034] An embodiment of the present application provides a bearing device, please refer to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a bearing device provided by an embodiment of the present application, Figure 2 is a structural schematic diagram of another bearing device provided by an embodiment of the present application. The bearing device can include a base 100, a first bearing table 200 and a second bearing table 300.

[0035] The base 100 in the bearing device can have a first support surface P1 and a second support surface P2 distributed on the same side. The first bearing table 200 in the bearing device can be fixedly connected with the base 100 on the first support surface P1 of the base 100, and the side of the first bearing table 200 away from the base 100 can be used to bear a shell in which a functional component is installed. Here, the functional component installed in the shell can be an internal accessory in a terminal device, including a printed circuit board, a loudspeaker and a battery, etc.

[0036] The second bearing table 300 in the bearing device can be movably connected with the base 100 on the second support surface P2 of the base 100, and the side of the second bearing table 200 away from the base 100 is used to bear a screen. The screen can be connected with the functional component installed in the shell through a wire harness. Here, since the screen and the shell are assembled by using a flip-chip process, the screen is always connected with the functional component installed in the shell through the wire harness.

[0037] In the present application, as Figure 1As shown, after the second carrier table 300 moves to the first position relative to the base 100 in the direction away from the first carrier table 200, there is no part of the first carrier table 200 covered by the second carrier table 300, i.e. the first carrier table 200 can be completely exposed. In this way, the shell with the functional components mounted thereon can be placed on the first carrier table.

[0038] It should be noted that after the second carrier table 300 moves to the first position so that there is no part of the first carrier table 200 covered by the second carrier table 300, the worker can hold the screen and the shell with the functional components mounted thereon with both hands respectively to place the shell with the functional components mounted thereon on the first carrier table 200 first. In this process, in order to avoid the disconnection of the wires, the screen can be held vertically.

[0039] Then, after the first carrier table 200 carries the shell, the second carrier table 300 can move in the direction towards the first carrier table 200. As shown, Figure 2 As shown, after the second carrier table 300 moves to the second position relative to the base 100 in the direction towards the first carrier table 200, there can be a part of the first carrier table 200 covered by the second carrier table 300, and at this time, the screen can be placed on the second carrier table 300 so that the screen on the second carrier table 300 can be close to the shell on the first carrier table 200. In this way, in the subsequent dispensing process, the screen and the shell with the functional components mounted thereon will not move relative to each other, and thus the wires connected to the screen and the functional components mounted in the shell at two ends will not be pulled, so as to ensure that the connection between the wires and the screen and the functional components mounted in the shell at two ends is highly reliable.

[0040] It should be noted that the first position described above is not a specific position, but only needs to ensure that after the second carrier table 300 moves to the first position relative to the base 100 in the direction away from the first carrier table 200, there is no part of the first carrier table 200 covered by the second carrier table 300. The second position described above can be the position where the second carrier table 300 is closest to the first carrier table 200, i.e. after the second carrier table 200 moves to the second position relative to the base 100 in the direction towards the first carrier table 200, the second carrier table 200 cannot continue to move in the direction towards the first carrier table 200. The second position defined in this way can ensure that the wires connected to the screen and the functional components mounted in the shell at two ends will not be pulled.

[0041] In summary, the embodiment of the present application provides a bearing device, comprising a base, a first bearing table and a second bearing table. After the second bearing table is moved to a first position relative to the base in a direction away from the first bearing table, so that there is no part of the first bearing table covered by the second bearing table, the shell with the functional components mounted thereon can be placed on the first bearing table. Then, the second bearing table can be moved in a direction close to the first bearing table, and after the second bearing table is moved to a second position relative to the base in a direction close to the first bearing table, there can be a part of the first bearing table covered by the second bearing table, at this time, the screen can be placed on the second bearing table, so that the screen located on the second bearing table can be close to the shell located on the first bearing table. In this way, in the subsequent dispensing process, the screen and the shell with the functional components mounted thereon will not move relative to each other, and thus the flat cables connected to the screen and the functional components mounted in the shell at both ends will not be pulled, so as to ensure that the connection between the screen and the functional components mounted in the shell at both ends of the flat cable is highly reliable.

[0042] It should be noted that, as shown in Figure 1 , the side of the first bearing table 200 away from the base 100 can have a bearing groove K adapted to the shell. After the second bearing table 300 is moved to a first position relative to the base 100 in a direction away from the first bearing table 200, there is no part of the first bearing table 200 covered by the second bearing table 300, that is, the bearing groove K of the first bearing table 200 can be completely exposed, so that the shell can be placed in the bearing groove K of the first bearing table 200. And after the second bearing table 300 is moved to a second position relative to the base 100 in a direction close to the first bearing table 200, there is a part of the first bearing table 200 covered by the second bearing table 300, that is, the part of the shell located in the bearing groove K of the first bearing table 200 can be covered. In this way, the screen located on the second bearing table 300 can be close to the shell located on the first bearing table 200, so that the flat cables connected to the screen and the functional components mounted in the shell at both ends will not be pulled.

[0043] Optionally, please refer to Figure 3 , Figure 3is a structural schematic diagram of another bearing device provided by an embodiment of the present application. The second bearing table 300 in the bearing device can include a sliding part 301 and a bearing part 302 connected together. The sliding part 301 in the second bearing table 300 can be movably connected to the base 100 on the second support surface P2 of the base 100, and the side of the bearing part 302 in the second bearing table 300 facing away from the sliding part 301 can be used to bear the screen. The included angle g between the side of the bearing part 302 in the second bearing table 300 facing away from the sliding part 301 and the area of the second support surface P2 in which the second bearing table is distributed is an acute angle. In this way, the distance between the screen located on the bearing part 302 in the second bearing table 300 and the shell located on the first bearing table 200 is appropriate, and the wires connected to the screen and the functional components installed in the shell at two ends will not be pulled, avoiding the possibility that the wires are loosened from the screen or the functional components installed in the shell.

[0044] It should be noted that in the subsequent dispensing process, the dispensing device can be located on one side of the part of the first bearing table 200 not covered by the second bearing table 300, so that the included angle g between the side of the bearing part 302 in the second bearing table 300 facing away from the sliding part 301 and the area of the second support surface P2 in which the second bearing table is distributed is an acute angle, which can avoid interference between the dispensing device and the second bearing table 300 bearing the screen.

[0045] It should be noted that the included angle g between the side of the bearing part 302 in the second bearing table 300 facing away from the sliding part 301 and the area of the second support surface P2 in which the second bearing table is distributed can be 25°. In this way, while ensuring that the connection between the wires and the screen and the functional components installed in the shell is relatively reliable, interference between the dispensing device and the second bearing table 300 can also be avoided.

[0046] Optionally, as shown in Figure 3 The end of the bearing part 302 in the second bearing table 300 and the sliding part 301 can be rotatably connected. The second bearing table 300 can further include an angle adjusting assembly 303, which can be located between the sliding part 301 and the bearing part 302, and the angle adjusting assembly 303 can be connected to the other end of the bearing part 302 and the sliding part 301, respectively. In this way, the angle adjusting assembly 303 can be used to adjust the included angle g between the side of the bearing part 302 in the second bearing table 300 facing away from the sliding part 301 and the area of the second support surface P2 in which the second bearing table 300 is distributed.

[0047] It should be noted that the included angle g between the side of the bearing part 302 facing away from the sliding part 301 and the area of the second support surface P2 in which the second bearing table 300 is distributed can be adjusted when the second bearing table 300 is in the first position, so as to ensure that the angle of the bearing part 302 in the second bearing table 300 is appropriate after the second bearing table 300 moves to the second position.

[0048] Optionally, please refer to Figure 4 , Figure 4 is a structural schematic diagram of still another bearing device provided by the embodiment of the present application. The angle adjusting assembly 303 in the second bearing table 300 can include a first connecting piece 3031, a second connecting piece 3032 and a fastener 3033. The first connecting piece 3031 in the angle adjusting assembly 303 can be fixedly connected to the side of the sliding part 301 facing the bearing part 302, the second connecting piece 3032 in the angle adjusting assembly 303 can be fixedly connected to the side of the bearing part 302 facing the sliding part 301, and the fastener 3033 in the angle adjusting assembly 303 can be used to fasten the first connecting piece 3031 and the second connecting piece 3032 after the first connecting piece 3031 moves relative to the second connecting piece 3032.

[0049] Here, the first connecting piece 3031 in the angle adjusting assembly 303 moves relative to the second connecting piece 3032, that is, the included angle g between the side of the bearing part 302 facing away from the sliding part 301 and the area of the second support surface P2 in which the second bearing table 300 is distributed is adjusted. In this way, after the included angle g is adjusted to an appropriate angle, the fastener 3033 can fasten the first connecting piece 3031 and the second connecting piece 3032, so as to ensure that the adjusted angle g does not change.

[0050] Optionally, as shown in Figure 4 , the first connecting piece 3031 in the angle adjusting assembly 303 can have an arc-shaped slot S2, and the second connecting piece 3032 in the angle adjusting assembly 302 can have a connecting hole S1 in communication with the arc-shaped slot S2. The fastener 3033 in the angle adjusting assembly 303 can pass through the connecting hole S1 of the first connecting piece 3031 and the arc-shaped slot S2 of the second connecting piece 3032, so as to fasten the first connecting piece 3031 and the second connecting piece 3032.

[0051] For example, the fastener 3033 in the angle adjusting assembly 303 can include a bolt and a nut, the diameter of the head of the bolt can be greater than the width of the connecting hole S1 of the first connecting piece 3031 and greater than the diameter of the arc-shaped slot S2 of the second connecting piece 3032, and the shank of the bolt can pass through the connecting hole S1 of the first connecting piece 3031 and the arc-shaped slot S2 of the second connecting piece 3032. In this way, when it is needed to adjust the included angle g between the side of the bearing part 302 facing away from the sliding part 301 and the area in the second support surface P2 where the second bearing table 300 is distributed, the bolt can be taken out of the arc-shaped slot S2 and the connecting hole S1, and when it is needed to fasten the first connecting piece 3031 and the second connecting piece 3032, the first connecting piece 3031 and the second connecting piece 3032 can be clamped between the head of the bolt and the nut after the shank of the bolt passes through the arc-shaped slot S2 and the connecting hole S1.

[0052] Optionally, as shown in Figure 5 , Figure 5 is a structural schematic diagram of a bearing device provided by another embodiment of the present application. The second bearing surface P2 of the base 100 can have a guide slide rail 101, and the side of the sliding part 301 in the second bearing table 300 facing away from the bearing part 302 can have a guide slide block 3011 in sliding connection with the guide slide rail 101. The guide slide rail 101 can have a first end A1 and a second end A2 arranged oppositely, the first end A1 of the guide slide rail can be distributed towards the first bearing table 200, and the second end of the guide slide rail 101 can be distributed away from the first bearing table 200.

[0053] It should be noted that after the guide slide block 3011 in the second bearing table 300 slides to the second end A2 of the guide slide rail 101, there will be no part of the first bearing table 200 covered by the second bearing table 300, and the second bearing table 300 can be in the first position. After the guide slide block 3011 in the second bearing table 300 slides to the first end A1 of the guide slide rail 101, there will be a part of the first bearing table 200 covered by the second bearing table 300, and the second bearing table 300 can be in the second position.

[0054] It should also be noted that in the direction perpendicular to the movement direction of the sliding part 301 in the second bearing table 300, the second support surface P2 of the base 100 can have two guide slide rails 101 arranged oppositely. Correspondingly, in the direction perpendicular to the movement direction of the sliding part 301 in the second bearing table 300, the two sides of the sliding part 301 arranged oppositely can each have a guide slide block 3011. In this way, the stability of the movement of the second bearing table 300 is better.

[0055] Optionally, as shown in Figure 5 and Figure 6 , Figure 6is a structural schematic view of another bearing device provided by another embodiment of the present application. The second support surface P2 of the base 100 can also have a first limiting piece 102 and a second limiting piece 103. The first limiting piece 102 can be located at the first end A1 of the guide slide rail 101, and the second limiting piece 103 can be located at the second end A2 of the guide slide rail 101. Here, the first limiting piece 102 and the second limiting piece 103 can both be used to limit the guide sliding block 3011 in the second bearing table 300, so as to avoid the guide sliding block 3011 from being disengaged from the guide slide rail 101.

[0056] Optionally, as shown in Figure 6 The bearing part 302 in the second bearing table 300 can have a hollow area V. After the bearing part 302 bears the screen, part of the screen can be exposed through the hollow area V of the bearing part 302, and the part of the screen exposed through the hollow area V can be adsorbed by the handheld part. Here, the handheld part can be a suction ball, and the worker can hold the suction ball to adsorb the screen, so as to realize the taking and placing of the screen. In this way, the worker is facilitated to take and place the screen, and time is saved.

[0057] Optionally, the bearing device can also include a driving assembly located on the base 100. The driving assembly can be connected with the second bearing table 300, and the driving assembly can be used to drive the second bearing table 300 to move in the direction towards the first bearing table 200, or to drive the second bearing table 300 to move in the direction away from the first bearing table 200. In this way, the worker does not need to manually move the second bearing table, and the movement of the second bearing table 300 is driven by the driving assembly, so time is saved.

[0058] It should be noted that the bearing device can have a control button. After the first bearing table 200 bears the shell, the worker can press the control button to control the second bearing table 300 to move in the direction towards the first bearing table 200 to the first position. In this way, the worker is facilitated to operate, and time is saved.

[0059] In summary, the embodiment of the present application provides a bearing device, comprising a base, a first bearing table and a second bearing table. After the second bearing table is moved to a first position relative to the base in a direction away from the first bearing table, so that there is no part of the first bearing table covered by the second bearing table, the shell with the functional components mounted thereon can be placed on the first bearing table. Then, the second bearing table can be moved in a direction close to the first bearing table, and after the second bearing table is moved to a second position relative to the base in a direction close to the first bearing table, there can be a part of the first bearing table covered by the second bearing table, at this time, the screen can be placed on the second bearing table, so that the screen located on the second bearing table can be close to the shell located on the first bearing table. In this way, in the subsequent dispensing process, the screen and the shell with the functional components mounted thereon will not move relative to each other, and thus the flat cables connected to the screen and the functional components mounted in the shell at both ends will not be pulled, thereby ensuring the reliability of the connection between the flat cables and the screen and the functional components mounted in the shell at both ends.

[0060] The embodiment of the present application also provides a dispensing system, comprising a dispensing device and a bearing device, and the bearing device in the dispensing system is any of the bearing devices described above. After the second bearing table in the bearing device is in the second position, the dispensing device can be located on one side of the part of the first bearing table in the bearing device which is not covered by the second bearing table. In this way, the dispensing device can dispense the part of the shell on the first bearing table which is not covered.

[0061] It should be noted that in the terminal device, after the shell is mounted with the functional components, the screen connected with the flat cable needs to be fixedly connected with the middle frame in the shell to realize the assembly of the terminal device. Therefore, the dispensing device needs to dispense the part of the middle frame in the shell which is not covered.

[0062] For example, in the case of a tablet computer, since part of the structure in the front camera area of the tablet computer interferes with the screen, such as the front camera sealing rubber sleeve, TOF sealing silica gel sleeve and light sensing sealing silica gel sleeve, the connection strength between the screen and the middle frame is low by using the back adhesive process. Therefore, two dispensing can be performed in the front camera area of the tablet computer to improve the connection strength between the screen and the middle frame. In this way, when the bearing device in the present application is used to bear the shell of the tablet computer, the front camera area of the shell can be placed in the part of the first bearing table which is not covered by the second bearing table, so that the dispensing device can dispense the front camera area of the shell.

[0063] In the present application, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. The term "a plurality of" means two or more, unless otherwise explicitly limited.

[0064] The above merely provides the optional embodiments of the present application, but does not intend to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
