[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In the present invention, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; while "inside" and "outside" refer to the outline of the device.

[0030] Throughout the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," or "some examples" are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of the present disclosure. Schematic representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the particular features, structures, materials, or characteristics described may be included in any one or more embodiments or examples in any suitable manner.

[0031] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0032] When describing some embodiments, the term "connected" and its derivatives may be used. For example, when describing some embodiments, the term "connected" may be used to indicate that two or more components are in direct physical or electrical contact with each other. The embodiments disclosed herein are not necessarily limited to the embodiments disclosed herein.

[0033] As used herein, “approximately” includes the stated value and an average value that is within an acceptable range of deviation from the particular value, where the acceptable range of deviation is determined by one of ordinary skill in the art taking into account the measurements in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system).

[0034] “A and / or B” includes the following three combinations: A only, B only, and a combination of A and B.

[0035] In related technologies, when two components need to be mounted, manual operations are often used. For example, an operator would remove the corresponding components individually, align the two, and then press them together to complete the mounting process. This method often results in low product mounting efficiency and hinders production schedules.

[0036] Based on this, Figure 1 As shown, the present disclosure provides a placement device 100 , which includes a transmission mechanism 10 , a robot arm mechanism 30 and a lifting platform mechanism 20 .

[0037] The transport mechanism 10 is configured to carry the first component 81 and transport the first component 81 .

[0038] The robot mechanism 30 is configured to pick up the second component 82 and align the second component 82 with the first component 81 .

[0039] The lifting platform mechanism 20 is disposed on one side of the transmission mechanism 10 and is located on the transmission path of the first component 81. That is, the first component 81 will pass through the lifting platform mechanism 20 during the transmission process of the transmission mechanism 10.

[0040] The lifting platform mechanism 20 is configured to: lift the first component 81 after the first component 81 is transferred to the position of the lifting platform mechanism 20 to make the second component 82 and the first component 81 fit together; and lower it after the assembly component 83 is formed to place the assembly component 83 on the transmission mechanism 10.

[0041] In the placement equipment 100 described above, the lifting platform mechanism 20 can lift the first component 81 located on the conveyor mechanism 10, and then align and align the second component 82 with the first component 81 to form an assembly 83. The lifting platform mechanism 20 then lowers the assembly 83 and places it on the conveyor mechanism 10 for transport. This simple and efficient process ensures excellent placement of the first component 81 and the second component 82, while also facilitating the transport of the assembly 83 to the next process node.

[0042] Specifically, the lifting platform mechanism 20 elevates the first component 81, resulting in a short travel distance, which prevents the first component 81 from moving a large distance and thus reducing work efficiency. Furthermore, since the lifting platform mechanism 20 elevates the first component 81, it moves away from the conveyor mechanism 10. This prevents the pressure exerted on the first and second components 81, 82 during the bonding process from being transmitted to the conveyor mechanism 10, potentially causing damage to the conveyor mechanism 10. Furthermore, a single conveyor mechanism 10 can simultaneously transport the first component 81 and the assembly component 83, effectively reducing the space occupied by the placement equipment 100.

[0043] In some examples, after the robot arm mechanism 30 aligns the second component 82 with the first component 81 , the lifting platform mechanism 20 may lift the first component 81 and move it toward the second component 82 to achieve placement of the first component 81 and the second component 82 .

[0044] In other examples, after the lifting platform mechanism 20 lifts the first component 81 to a certain distance, the robot arm mechanism 30 can align the second component 82 with the first component 81 and move the second component 82 toward the first component 81 to achieve mounting of the two.

[0045] In some other examples, after the robotic arm mechanism 30 aligns the second component 82 with the first component 81, the lifting platform mechanism 20 and the robotic arm mechanism 30 can operate simultaneously, so that the first component 81 and the second component 82 move closer to each other and are squeezed, thereby achieving the placement of the first component 81 and the second component 82.

[0046] The specific position of the lifting platform mechanism 20 can be arranged as needed, as long as it can lift the first element 81, fit the first element 81 and the second element 82, and then form an assembly component and then lower it. The embodiment of the present disclosure does not limit the specific position of the lifting platform mechanism 20.

[0047] In some examples, such as Figure 1 As shown, the transmission mechanism 10 has a first end 101 and a second end 102 , and the transmission mechanism 10 transmits along a direction from the first end 101 toward the second end 102 .

[0048] In some examples, the lifting platform mechanism 20 is located between the first end 101 and the second end 102. In this arrangement, the first component 81 can be placed on the transmission mechanism 10 near the first end 101, and the second end 102 of the transmission mechanism 10 can collect the assembly component 83. The first component 81 and the assembly component 83 can be transported using one transmission mechanism 10, which can effectively reduce the space occupied by the placement equipment 100.

[0049] In some embodiments, the first element 81 and the second element 82 are each one of a liquid crystal display and a cover glass. In other words, the first element 81 is one of the liquid crystal display and the cover glass, and the second element 82 is the other of the liquid crystal display and the cover glass. In this case, the assembly 83 is a display panel.

[0050] In the related art of display panel assembly, the operator first places the LCD screen at the marked position, then places a positioning jig. After that, the cover glass with double-sided tape is placed on the LCD screen. The double-sided tape is then manually rolled to the position, thereby fixing the LCD screen and cover glass together to form the display panel. This method requires a lot of manual coordination during operation, resulting in low production efficiency. Furthermore, manually forming a display panel typically takes 15-20 minutes, which is time-consuming and labor-intensive. Furthermore, manual operation often results in large errors, leading to problems such as low yield and poor quality of finished products.

[0051] The above-mentioned mounting device 100 is applied to the mounting of display panels, which can greatly reduce the mounting time of a display panel, thereby improving the production efficiency of the display panels.

[0052] In some examples, the first component 81 is a cover glass and the second component 82 is a liquid crystal display. The cover glass is placed on the transmission mechanism 10 without the need for film tearing, which helps improve the mounting efficiency of the cover glass and the liquid crystal display.

[0053] In some embodiments, as Figures 1-4 As shown, the transmission mechanism 10 includes a plurality of pulleys 104 for carrying and transmitting the first component 81. That is, the first component 81 is directly attached to the pulleys 104 during the transmission process and is transmitted by the rotation of the pulleys 104.

[0054] The lifting platform mechanism 20 includes a driving member 211 and a support plate 221. The support plate 221 has a plurality of hollow portions 2210, and each pulley 104 is located in a hollow portion 2210. The driving member 211 is configured to drive the support plate 221 to rise or fall, and the support plate 221 is configured to support the first component 81. The support plate 221 has a support plane, which is used to support the first component 81. During the process of the support plate 221 rising or falling, it can drive the first component 81 to rise or fall synchronously. Because the pulley 104 is located in the hollow portion 2210 of the support plate 221, it can avoid contact with the pulley 104 during the process of the support plate 221 rising or falling, thereby ensuring the stable movement of the support plate 221.

[0055] Through the above arrangement, the support plate 221 can effectively support the first component 81, thereby preventing uneven force on the first component 81 during the bonding process, which could lead to poor bonding results. Furthermore, after being raised, the support plate 221 is positioned away from the pulley 104 of the transmission mechanism 10, thereby preventing the first component 81 and the second component 82 from exerting pressure on the pulley 104 during the bonding process, potentially damaging it.

[0056] In some examples, multiple pulleys 104 can be arranged along the second direction Y and connected by a rotating shaft to form a pulley assembly, and the multiple pulley assembly is arranged along the first direction X to achieve stable support and transportation of the first component 81. The first direction X is the direction from the first end 101 to the second end 102 or the direction from the second end 102 to the first end 101, and the second direction Y is perpendicular to the first direction X.

[0057] When the plurality of pulleys 104 are connected and driven via a rotating shaft, the support plate 221 needs to be disposed above the rotating shaft to prevent the support plate 221 from contacting the rotating shaft and affecting the rotation of the rotating shaft.

[0058] The portion of the transmission mechanism 10 corresponding to the support plate 221 uses the pulley 104 to carry and transport the first component 81. The remaining portion of the transmission mechanism 10 can use a conveyor belt or other means to carry and transport the first component 81. This disclosure is not limited to this aspect.

[0059] For ease of description, the embodiment of the present disclosure is described by taking an example in which each part of the transmission mechanism 10 carries and transmits the first element 81 through the pulley 104 .

[0060] Exemplarily, the transmission mechanism 10 includes a mounting frame 103 and a plurality of pulley blocks arranged along a first direction X. Each pulley block includes a plurality of pulleys 104 arranged along a second direction Y. The pulleys in two adjacent pulley blocks may be staggered, thereby improving the load-bearing stability of the first element 81.

[0061] In some examples, the transmission mechanism 10 further includes a driver for driving all the pulley groups to work. When the driver is working, the multiple pulley groups operate synchronously and move the first element 81 located above them; when the driver stops working, the first element 81 remains stationary.

[0062] Of course, the driver can include multiple sub-drivers, each of which drives a pulley assembly located at different locations of the transmission mechanism 10, thereby increasing the operational flexibility of the transmission mechanism 10. When the driving frequencies of the multiple sub-drivers are consistent, the rotation frequencies of all pulley assemblies remain consistent.

[0063] Exemplarily, the lifting platform mechanism 20 may be located below the transmission mechanism 10 , which is beneficial for lifting the first component 81 .

[0064] In some examples, the support plate 221 can be made of steel. Steel has good rigidity and can provide a good load-bearing effect on the first element 81. In addition, steel has good flatness, which can prevent warping that can cause uneven force on the first element 81 and cause it to break.

[0065] In some examples, the outer frame area of ​​the support plane of the support plate 221 is larger than the area of ​​the first element 81, thereby providing good and effective support for the first element 81 and preventing the first element 81 from being damaged due to local excessive force.

[0066] In some embodiments, a suction member is provided on a side of the support plate 221 away from the driving member 211, and the suction member is configured to adsorb the first component 81 onto the support plate 221. The adsorption effect of the suction member can stably fix the first component 81 on the support plate 221, thereby preventing displacement of the first component 81 during the bonding process with the second component 82, which could result in inaccurate bonding between the two and thus reduce the quality of display panel bonding.

[0067] In some examples, multiple groups of adsorbents are provided and evenly distributed on the support plate 221. Through the adsorption effect of the adsorbents, the force exerted on the first element 81 and the second element 82 when they are attached can be well distributed to each adsorbent, thereby balancing the force.

[0068] In some embodiments, the mounting device 100 further includes a vacuum pump, the support plate 221 has an opening and a hollow inner cavity, and the working end of the vacuum pump is connected to the opening, so that the vacuum pump can suck air into the inner cavity of the support plate 221 through the opening, so that the inner cavity of the support plate 221 is in a vacuum state.

[0069] In this case, the adsorbent has an adsorption end and a connection end. The adsorption end is connected to the inner cavity of the support plate 221 through the connection end, and the adsorption end is configured to be attached to the first component 81. In this way, the adsorbent acts as a vacuum adsorbent, thereby adsorbing and fixing the first component 81. For example, the adsorbent can be a vacuum suction cup. The adsorption end of the vacuum suction cup has a large area, which can improve the adsorption stability of the first component 81.

[0070] When the first component 81 needs to be fixed, the vacuum pump is turned on to adsorb the first component 81. When the first component 81 does not need to be fixed, the vacuum pump is turned off to fill the inner cavity of the support plate 221 with gas, so that the first component 81 can fall off from the adsorbent.

[0071] Specifically, when the driving member 211 drives the support plate 221 to rise and the suction end of the suction member contacts the first component 81, the vacuum pump is turned on, so that the first component 81 is fixed to the support plate 221. After the driving member 211 drives the support plate 221 to descend and the assembly component 83 formed by the first component 81 and the second component 82 contact the pulley block 104, the vacuum pump is turned off, so that the assembly component 83 is completely separated from the suction member, so that the assembly component 83 can continue to be transported on the conveying mechanism 10.

[0072] In some examples, a plurality of adsorption members may be located between two adjacent pulley blocks 104 , which helps to form a hollow inner cavity in the support plate 221 , thereby ensuring the adsorption effect of the adsorption member on the first element 81 .

[0073] In some embodiments, as Figure 4-Figure 5 As shown, the driving member 211 includes a driving motor, and a first screw rod 213 is provided at the output end of the driving motor. The length direction of the first screw rod 213 is consistent with the direction of lifting or lowering of the support plate 221, and the driving motor is configured to drive the first screw rod 213 to rotate; a first sleeve 214 is provided on the first screw rod 213 and slides along the length direction of the first screw rod 213. The first sleeve 214 is threadedly connected to the first screw rod 213, and the support plate 221 is connected to the first sleeve 214 through a first connecting member.

[0074] Exemplarily, the first sliding sleeve 214 can be slidably connected to the mounting frame 103 of the transmission mechanism 10. For example, the mounting frame 103 is provided with a slide rail, and the first sliding sleeve 214 is also embedded in the slide rail, so that the first sliding sleeve 214 only slides along the length direction of the first screw rod 213.

[0075] As another example, the first connecting member or the support plate 221 can be slidably connected to the mounting bracket 103, so that the first sleeve 214, the first connecting member and the support plate 221 as a whole can move along the length direction of the first screw rod 213 under the rotation of the first screw rod 213.

[0076] As for the sliding connection method, it can be set by cooperating between the sliding rail and the sliding sleeve. As long as the purpose of the above-mentioned sliding connection can be achieved, it is within the scope of consideration of the present disclosure.

[0077] In some examples, such as Figure 4-Figure 5 As shown, the first connecting member includes a frame 223 mounted outside the first sliding sleeve 214 and a cross bar 222 connected to the frame 223. The frame 223 is fixedly connected to the first sliding sleeve 214. The cross bar 222 extends along the first direction X. The cross bar 222 and the support plate 221 are connected by multiple vertical bars (the vertical bars extend in the direction of lifting or lowering of the first element 81). This is beneficial to improving the supporting stability of the first connecting member on the support plate 221.

[0078] In some examples, a first bearing sleeve 1011 is provided at one end of the first screw rod 213 away from the drive motor, and the first bearing sleeve 1011 is fixed to the mounting frame 103. This arrangement is conducive to improving the stability of the first screw rod 213, thereby ensuring that it stably drives the first sleeve 214 to move up and down.

[0079] In some embodiments, a second screw rod is further provided at the output end of the driving motor, and the second screw rod is arranged parallel to the first screw rod 213. The driving motor is also configured to drive the second screw rod to rotate. A second sleeve is provided on the second screw rod and slides along the length direction of the second screw rod. The second sleeve is threadedly connected to the second screw rod, and the support plate 221 is also connected to the second sleeve through a second connecting member.

[0080] The second connecting member connects the support plate 221 and the second sleeve, thereby improving the stability of the support plate 221. The second screw and the second sleeve cooperate to drive the second sleeve and the support plate 221 to move synchronously through the rotation of the second screw, thereby ensuring the stability of the support plate 221 in moving up and down.

[0081] In some examples, the first screw rod 213 and the second screw rod are respectively located on both sides of the transmission mechanism 10 in the second direction Y, which helps to improve the movement stability of the support plate 221.

[0082] It should be noted that the arrangement of the second screw rod and the second sliding sleeve is the same as that of the first screw rod and the first sliding sleeve, so they are not shown in the figure.

[0083] In some examples, a second bearing sleeve 1012 is provided at one end of the second screw away from the drive motor, and the second bearing sleeve 1012 is fixed to the mounting bracket 103. This arrangement is conducive to improving the stability of the second screw, thereby ensuring that it stably drives the second sleeve to move up and down.

[0084] In some embodiments, as Figure 4 As shown, the output shaft 212 of the driving motor is arranged along the second direction Y, and the output shaft 212 of the driving motor acts on the first screw rod 213 and the second screw rod, so that the first screw rod 213 and the second screw rod can rotate synchronously, thereby allowing the support plate 221 to move up and down stably.

[0085] A gear assembly may be provided between the output shaft 212 of the driving motor and the first screw rod 213 (or the second screw rod) to convert the rotation of the output shaft 212 into the rotation of the first screw rod 213 in different directions.

[0086] For example, the gear assembly may include a straight bevel gear, and the output shaft 212 may drive the first screw rod 213 to rotate through the transmission of the straight bevel gear.

[0087] In some embodiments, the placement device 100 further includes a control system and a position sensor. The position sensor is located on a side of the lift mechanism 20 away from the first end 101. The position sensor and the driver of the transmission mechanism 10 are electrically connected to the control system. The position sensor is configured to detect the position of the first component 81 when it is transferred to the lift mechanism 20 and transmit a position signal to the control system. The control system is configured to receive the position signal and issue a control signal. The driver is configured to receive the control signal and control the lifting of the first component 81.

[0088] Specifically, when the position sensor detects that the first element 81 reaches the position of the lifting platform mechanism 20, it feeds back the position signal to the control system. After receiving the position signal, the control system sends a control signal and controls the driver to stop working through the control signal.

[0089] This arrangement allows for precise control of the position of the first component 81. Once the first component 81 is above the lifting platform mechanism 20, the driver stops, and the transmission mechanism 10 stops transmitting. At this point, the drive motor of the lifting platform mechanism 20 is activated, causing the first component 81 to move toward the second component 82, thereby facilitating placement of the first and second components 81, 82. This facilitates automated placement of the first and second components 81, 82, thereby improving the efficiency of assembly assembly 83.

[0090] In some examples, the control system is also electrically connected to the drive motor, so that the lifting platform mechanism 20 can be automatically operated. Specifically, after receiving the position signal, the control system also sends another control signal to control the drive motor to operate, thereby moving the first element 81 toward the second element 82.

[0091] In some embodiments, as Figure 1 As shown, the mounting device 100 further includes a plurality of visual lenses 60 , each of which is configured to detect the coordinates of a corner of the first component 81 , and two of the plurality of visual lenses 60 are located at opposite corners of the first component 81 .

[0092] With this arrangement, the coordinates of at least the diagonal corners of the first component 81 can be measured using multiple visual lenses 60. When the first component 81 is rectangular, the coordinates of all corners of the first component 81 can be calculated using the coordinates of the diagonal corners. This is conducive to achieving precise positioning between the first component 81 and the second component 82, thereby improving the success rate of mounting the first component 81 and the second component 82.

[0093] In some examples, the plurality of vision lenses 60 includes three vision lenses 60, two of which are located at opposite corners of the first element 81, and another vision lens 60 is located at one of the remaining corners of the first element 81. This arrangement helps improve the accuracy of calculating the coordinates of each corner of the first element 81.

[0094] In some examples, the placement device 100 further includes multiple moving arms, each visual lens 60 is fixed to a moving arm, and each moving arm is configured to move along a first direction X and a second direction Y. In this way, the visual lens 60 can be moved by the moving arms, thereby facilitating automated measurement of the coordinates of each corner of the first component 81.

[0095] For example, the movable arm may be a rectangular coordinate robot, and the visual lens 60 is fixed to the end of the rectangular coordinate robot, so that the visual lens 60 is driven to move by the rectangular coordinate robot.

[0096] In some examples, multiple visual lenses 60 and a robotic arm mechanism 30 can be electrically connected to the above-mentioned control system. The visual lens 60 sends the measured coordinate data to the control system, and the control system can output a control signal to control the movement path of the robotic arm mechanism 30, so that the second element 82 can be accurately aligned with the first element 81.

[0097] This arrangement can ensure fully automated operation of the mounting of the second component 82 and the first component 81 , thereby greatly improving the assembly efficiency of both and also ensuring the yield rate of the assembly component 83 .

[0098] In some examples, when the first component 81 is a cover glass and the second component is a liquid crystal display, the control system can also calculate the coordinate information of the inner silk-screen edge of the cover glass using the coordinate data obtained from multiple visual lenses 60, thereby further ensuring the success rate of mounting the second component 82 and the first component 81.

[0099] In some embodiments, as Figure 1 As shown, the mounting device 100 also includes an auxiliary robot arm mechanism 70, the second component 82 has a first surface and a second surface, the auxiliary robot arm mechanism 70 is configured to pick up the second component 82 and make the first surface face away from the auxiliary robot arm mechanism; the robot arm mechanism 30 is configured to pick up the second component 82 from the auxiliary robot arm mechanism 70 and make the second surface face away from the robot arm mechanism 30.

[0100] With this arrangement, the two robotic arm mechanisms can achieve reversal of the active surface of the second element 82. The adhesive tape is provided on the second surface, and since the second surface faces away from the robotic arm mechanism 30, the second surface of the second element 82 can be bonded to the first element 81.

[0101] In some embodiments, as Figure 1 As shown, the placement device 100 further includes a loading mechanism 40 , which is used to update the loading of the second component 82 , so that the auxiliary robot mechanism 70 can continuously pick up the second component 82 at the position of the loading mechanism 40 .

[0102] Such an arrangement is conducive to further improving the automated operation of the placement device 100, thereby improving the placement efficiency of the assembly components.

[0103] In some embodiments, as Figure 1 As shown, the placement apparatus 100 further includes a film tearing mechanism 50, which is located between the robot arm mechanism 30 and the auxiliary robot arm mechanism 70. The film tearing mechanism 50 is configured to tear off the protective film on the second surface of the second component 82. This exposes the adhesive tape on the second surface, thereby facilitating the bonding between the second component 82 and the first component 81.

[0104] The provision of the film tearing mechanism 50 further automates the mounting arrangement 100, thereby further improving the mounting efficiency of the assembly components.

[0105] In some embodiments, as Figure 1 As shown, the robotic arm mechanism 30 includes a robotic arm 31 and a clamp 32 located at one end of the robotic arm 31 .

[0106] The robotic arm 31 is used to drive the fixture 32 for multi-directional movement and / or rotation. For example, the robotic arm 31 can be a six-axis robot. Six-axis robots typically have six joints that combine to create six degrees of freedom at their end. The fixture 32 is secured to the end of the six-axis robot. Six-axis robots offer advantages such as high flexibility, large payload capacity, and high positioning accuracy, making them ideal for driving the movement of the fixture 32.

[0107] like Figure 6 As shown, the clamp 32 includes a fixing plate 321 , on which is disposed at least one suction cup group 322 , each suction cup group 322 including one or more suction cups 3220 .

[0108] It should be noted that the suction cup group 322 is mainly divided by areas on the fixing plate 321, which will be described in detail below.

[0109] The suction cup group 322 can be fixed by using the fixing plate 321 , and the second component 82 can be fixed by the clamp 32 through the suction cups 3220 in the suction cup group 322 .

[0110] In some examples, the suction cup group 322 may include a plurality of suction cups 3220 , and the plurality of suction cups may form a more stable and effective fixation for the second component 82 .

[0111] For example, the plurality of suction cups 3220 may be evenly distributed along the circumference of the second element 82 , which is beneficial for improving the stability of the suction cup group 322 in adsorbing the second element 82 .

[0112] As another example, a portion of the plurality of suction cups 3220 are evenly distributed along the circumference of the second element 82 , and another portion is disposed at the center of the second element 82 . This helps to further improve the stability of the suction cup group 322 in adsorbing the second element 82 .

[0113] In some embodiments, as Figure 7 As shown, the fixing plate 321 has a first area S1 and a second area S2, and at least one suction cup group 322 includes a first suction cup group 3221 and a second suction cup group 3222. The first suction cup group 3221 is located in the first area S1, and the second suction cup group 3222 is located in the second area. The first suction cup group 3221 and the second suction cup group 3222 are configured to adsorb second components 82 of different sizes.

[0114] With this arrangement, the suction cup groups located in the two areas can be used to adsorb second components 82 of different sizes, thereby enabling the mounting of display panels of different sizes.

[0115] It should be noted that the areas divided on the fixing plate 321 (such as the first area S1 and the second area S2) are Figure 7 The area indicated by the dotted box.

[0116] For example, when the first component 71 is a cover glass and the second component 82 is a liquid crystal display, the same fixture can be used to adsorb liquid crystal displays of different sizes, thereby enabling the mounting of display panels of different sizes. This greatly broadens the use scenarios of the mounting device 100, allowing flexible mounting of display panels according to actual needs.

[0117] In some examples, the first suction cup group 3221 includes a plurality of first suction cups, and the plurality of first suction cups are arranged around the first area S1 , which helps to ensure the stability of the first suction cup group 3221 in adsorbing the second component 82 .

[0118] For example, the plurality of first suction cups are evenly arranged around the first area S1 , which helps to improve the stability of the first suction cup group 3221 in adsorbing the second component 82 .

[0119] In some examples, the second suction cup set 3222 includes a plurality of second suction cups, which are arranged around the second area S2 , so as to ensure the stability of the second suction cup set 3222 in adsorbing the second component 82 of another size.

[0120] For example, the plurality of second suction cups are evenly arranged around the second area S2 , which helps to improve the stability of the second suction cup group 3222 in adsorbing the corresponding second component 82 .

[0121] In some embodiments, as Figure 7 As shown, the second area S2 at least partially surrounds the first area S1. This arrangement reduces the area of ​​the fixing plate 321, thereby facilitating a compact arrangement of the fixture 32 and, in turn, reducing the space occupied by the placement apparatus 100. Furthermore, the reduced area of ​​the fixing plate 321 also reduces the weight of the fixture 32, thereby improving the stability of the movement of the fixture 32 by the robot arm 31.

[0122] In some examples, the second area S2 completely surrounds the first area S1 , which can minimize the area of ​​the fixing plate 321 , thereby further reducing the space occupied by the placement device 100 and improving the stability of the movement of the fixture 32 .

[0123] In some embodiments, as Figure 7 As shown, the first suction cup group 322 includes at least one shared suction cup 3224, which is also located within the second area S2. That is, the at least one shared suction cup 3224 is located within the overlapping region between the first area S1 and the second area S2. The shared suction cup 3224 participates in the suction process for second components 82 of varying sizes, thus reducing the total number of suction cups and effectively utilizing the space on the fixing plate 321.

[0124] In some embodiments, as Figure 7 As shown, the first area S1 and the second area S2 have a common edge M1 , and the at least one common suction cup 3224 may include a plurality of common suction cups 3224 , which are sequentially arranged along the length direction of the common edge M1 .

[0125] The provision of multiple shared suction cups 3224 can further reduce the total number of suction cups, which is beneficial to further improve the effective utilization of the space on the fixing plate 321.

[0126] In some examples, the plurality of common suction cups 3224 are arranged at equal intervals along the length direction of the common edge M1 , which can improve the adsorption stability of the common suction cups 3224 on the second component 82 .

[0127] In some embodiments, as Figure 7 As shown, the fixing plate 321 further has a third area S3, and the at least one suction cup group 322 further includes a third suction cup group 3223. The third suction cup group 3223 is configured to attract the second component 82, which is larger than the first suction cup group 3221 and the second suction cup group 3222. In other words, the area of ​​the third area S3 is larger than that of the second area S2.

[0128] With this arrangement, different suction cup groups located in the three areas can be used to absorb three different sizes of second components 82, thereby enabling the placement of three different sizes of display panels. For example, the placement device 100 can be used to place 65-inch, 75-inch, and 86-inch display panels. Of course, it can also be used to place display panels of other sizes.

[0129] In some examples, the third suction cup set 3223 includes a plurality of third suction cups, which are arranged around the third area S3, so as to ensure the stability of the third suction cup set 3223 in adsorbing the second component 82 of corresponding size.

[0130] For example, the plurality of third suction cups are evenly arranged around the third area S3, which helps to improve the stability of the third suction cup group 3223 in adsorbing the second component 82 of corresponding size.

[0131] In some embodiments, as Figure 7 As shown, the third area S3 at least partially surrounds the second area S2. This arrangement reduces the area of ​​the fixing plate 321, thereby facilitating a compact arrangement of the fixture 32 and, in turn, reducing the space occupied by the placement apparatus 100. Furthermore, the reduced area of ​​the fixing plate 321 also reduces the weight of the fixture 32, thereby improving the stability of the movement of the fixture 32 by the robot arm 31.

[0132] In some examples, the third area S3 completely surrounds the second area S2 , which can minimize the area of ​​the fixing plate 321 , thereby further reducing the space occupied by the subtraction mounting apparatus 100 and improving the stability of the movement of the fixture 32 .

[0133] In some embodiments, as Figure 7 As shown, the second suction cup group 3222 includes at least one shared suction cup, which is also located within the third area S3. That is, the at least one shared suction cup is located within the overlapping area between the second area S2 and the third area S3. The shared suction cup 3224 participates in the suction process for second components 82 of varying sizes, thus reducing the total number of suction cups and effectively utilizing the space on the fixing plate 321.

[0134] For example, the at least one shared suction cup may be the shared suction cup 3224 included in the first suction cup group 3221. Of course, it may also be a suction cup that exists only in the second area S2 and the third area S3 and is shared by the second area S2 and the third area S3, and the present disclosure does not limit this.

[0135] In some embodiments, as Figure 7 As shown, the third area S3 and the second area S2 also share the common edge M1 , and the at least one common suction cup includes a plurality of common suction cups, which are sequentially arranged along the length direction of the common edge M1 .

[0136] The provision of multiple shared suction cups can further reduce the total number of suction cups, which is beneficial to further improve the effective utilization of the space on the fixing plate 321.

[0137] In some examples, a plurality of common suction cups are arranged at equal intervals along the length direction of the common edge M1 , which can improve the adsorption stability of the common suction cups on the second component 82 .

[0138] In some embodiments, as Figure 7As shown, a first pressure pad 3231 is further provided on the periphery of the inner side of the first area S1. The first pressure pad 3231 is fixed to the fixed plate 321 through a first telescopic member. A first driving mechanism is also provided on the fixed plate 321. The first driving mechanism is configured to drive the first telescopic member to move in a direction close to or away from the fixed plate 321. In this way, the first pressure pad 3231 can be driven by the first driving mechanism to move in a direction away from the fixed plate 321, thereby applying pressure to the edge of the second element 82, so that the second element 82 can form a more stable fit with the first element 71.

[0139] In some examples, the first pressure pads 3231 are evenly distributed along the four sides of the inner side of the first region S1 , which helps to improve the uniformity and stability of the fit between the second component 82 and the first component 71 .

[0140] In some embodiments, as Figure 7 As shown, a second pressure pad 3232 is further provided on the periphery of the inner side of the second area S2, and the second pressure pad 3232 is fixed to the fixed plate 321 through a second telescopic member. A second driving mechanism is also provided on the fixed plate 321, and the second driving mechanism is configured to drive the second telescopic member to move in a direction close to or away from the fixed plate 321. In this way, the second pressure pad 3232 can be driven by the second driving mechanism to move in a direction away from the fixed plate 321, thereby applying pressure to the edge of the second element 82 of corresponding size, so that the second element 82 can form a more stable fit with the first element 71.

[0141] In some examples, the second pressure pads 3232 are evenly distributed along the four sides of the inner side of the second region S2 , which helps to improve the uniformity and stability of the fit between the second element 82 and the first element 71 .

[0142] In some examples, when the first region S1 and the second region S2 have a common edge M1 , a portion of the first pressure pad 3231 located at the common edge M1 is also shared by the second region S2 .

[0143] In some embodiments, as Figure 7 As shown, a third pressure pad 3233 is further provided on the periphery of the inner side of the third area S3, and the third pressure pad 3233 is fixed to the fixed plate 321 through a third telescopic member. The fixed plate 321 is also provided with a third driving mechanism, and the third driving mechanism is configured to drive the third telescopic member to move in a direction close to or away from the fixed plate 321. In this way, the third pressure pad 3233 can be driven by the third driving mechanism to move in a direction away from the fixed plate 321, thereby applying pressure to the edge of the second element 82 of corresponding size, so that the second element 82 can form a more stable fit with the first element 71.

[0144] In some examples, the third pressure pads 3233 are evenly distributed along the four sides of the inner side of the third region S3 , which helps to improve the uniformity and stability of the fit between the second element 82 and the first element 71 .

[0145] In some examples, when the third region S3 and the first region S1 have the common edge M1 , a portion of the first pressure pad 3231 located at the common edge M1 is also shared by the third region S3 .

[0146] It should be noted that Figure 7 The dotted box does not indicate the specific location of the corresponding area. In actual area division, the area corresponding to the dotted box includes the corresponding pressure pad. For example, the area of ​​the first area S1 should be greater than or equal to the area enclosed by the outermost edge of the first pressure pad 3231.

[0147] In some examples, such as Figure 7 As shown, at least two of the first region S1, the second region S2 and the third region S3 have mutually overlapping axes of symmetry.

[0148] Illustratively, a symmetry axis of the first region S1 coincides with a symmetry axis of the second region S2 .

[0149] As another example, a symmetry axis of the first region S1 coincides with a symmetry axis of the third region S3 .

[0150] As another example, a symmetry axis of the second region S2 coincides with a symmetry axis of the third region S3 .

[0151] As another example, a symmetry axis of the first region S1, a symmetry axis of the second region S2, and a symmetry axis of the third region S3 all coincide with each other.

[0152] This arrangement, on the one hand, can make the suction cups in different areas more regularly arranged, which is conducive to the adsorption of the second component 82; on the other hand, it can also make the above-mentioned multiple areas all located in the middle position of the fixed plate, thereby increasing the overall stability after the second component 82 is adsorbed.

[0153] In some embodiments, as Figure 6 As shown, the fixing plate 321 is further provided with a circuit board adsorption pad 324. When the second component 82 is a liquid crystal display, the circuit board adsorption pad 324 can adsorb the circuit board on one side of the liquid crystal display to prevent it from shaking during the movement of the robot arm 31, thereby ensuring the consistency and stability of the liquid crystal display before and after placement.

[0154] In some examples, the circuit board adsorption pad 324 can be located on one side of the common edge M1, so that when adsorbing LCD screens of different sizes, the circuit boards on the corresponding LCD screens can be adsorbed, thereby ensuring the stability of LCD screens of different sizes.

[0155] The embodiments of the present invention are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. At the same time, for those skilled in the art, according to the ideas of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
