Description

Technical Field

[0001] This invention relates to the field of production technology, and in particular to a production system for a vertical lathe and a display device. Background Technology

[0002] Display devices such as televisions and all-in-one PCs can display images and videos. They are ubiquitous electronic devices in modern life and have greatly enriched people's daily lives.

[0003] The production of display devices involves multiple processes, and after assembly into a complete unit, various tests, including display testing, are required. In existing technologies, the complete display device is transferred from the upstream station to the testing process via a conveyor line. Since the complete unit testing requires the display device to be in a vertical position, and in order to ensure the stability of the complete unit's transmission on the conveyor line, the complete unit is usually set horizontally or at a preset acute angle relative to the horizontal during transmission.

[0004] The above setup requires manual rotation of the display device to a vertical position when the machine is transferred from the conveyor line to the testing process, resulting in reduced testing efficiency. Furthermore, the manual intervention increases labor costs. Especially for larger display devices, the process of rotating the device to a vertical position can easily cause it to tip over and be damaged, or cause personal injury, thus affecting the smooth progress of the rotation process. Summary of the Invention

[0061] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0062] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0063] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0065] like Figure 1 and Figure 2 As shown, this embodiment provides a vertical machine that can be applied to a display device 4 production system. It is used to flip the display device 4 on the conveyor line 3 to a preset angle relative to the horizontal plane, thereby adjusting the position and orientation of the display device 4 on the conveyor line 3 to facilitate subsequent testing or other operations. The vertical machine provided in this embodiment is particularly suitable for adjusting the position and orientation of large display devices 4.

[0066] The display device production system includes a conveyor line 3 and a vertical machine. The conveyor line 3 is equipped with a screen support frame 5 for supporting and fixing the display device 4. The display device 4 is mounted on the screen support frame 5, and is positioned at a preset acute angle relative to the horizontal plane. The lower end of the display device 4 is rotatably connected to the screen support frame 5. The width of the conveyor line 3 is set along a first horizontal direction.

[0067] The vertical machine includes a flipping device 1 and a front blocking device 2, which are respectively arranged on opposite sides of the conveyor line 3. The flipping device 1 and the front blocking device 2 are used to abut against the back of the display device 4 and drive the display device 4 to flip to a preset angle relative to the horizontal plane. The front blocking device 2 includes a stop mechanism, and the vertical machine includes two stop mechanisms spaced apart in the second horizontal direction. Each stop mechanism can slide along the second horizontal direction so that the two stop mechanisms can be aligned with the two side frames 42 of the display device 4 respectively. The stop mechanism is used to abut against the front of the display device 4 at a preset tilt angle.

[0068] The vertical machine provided in this embodiment, by setting a flipping device 1, can drive the display device 4 to flip to a preset angle relative to the horizontal plane, thereby realizing the automatic flipping of the display device 4 and improving the automation and efficiency of the flipping of the display device 4. By setting a front blocking device 2, the front blocking device 2 can abut against the front of the display device 4 when it is flipped to the correct position, thereby preventing the display device 4 from over-flipping and tipping over, improving the flipping safety of the display device 4. At the same time, since there are two stop mechanisms, which can be directly opposite the two side frames 42 of the display device 4, the stop mechanisms abut against the side frames 42 of the display device 4 without contacting the screen body 41, effectively avoiding damage to the screen body 41 of the display device 4 by the stop mechanisms, further improving the flipping safety of the display device 4. At the same time, it also allows the flipped display device 4 to be clamped between the flipping device 1 and the front blocking device 2 and stably maintained in the flipped state, without the need for manual support of the display device 4 after flipping, and the front blocking device 2 will not obstruct the screen surface of the display device 4, effectively realizing the subsequent testing operations of the display device 4.

[0069] Preferably, in this embodiment, two front blocking devices 2 are provided, spaced apart along the second horizontal direction, and each front blocking device 2 includes a stop mechanism. This reduces the size of each front blocking device 2, improves the ease of installation, and allows the positions of the two stop mechanisms to be adaptively set according to the width of the display device 4, improving the versatility of the front blocking devices 2 and making the vertical machine more suitable for flipping larger display devices 4. In other embodiments, only one front blocking device 2 may be provided, comprising two stop mechanisms spaced apart along the second horizontal direction.

[0070] It is worth noting that in this embodiment, the structure of the conveyor line 3 and the screen support frame 5 can adopt the existing structure. This embodiment only describes the structure of the flipping device 1 and the front blocking device 2 in detail, and does not elaborate on or limit the structure of the conveyor line 3 and the screen support frame 5.

[0071] In this embodiment, the first horizontal direction is perpendicular to the second horizontal direction. In other embodiments, the first horizontal direction and the second horizontal direction are also set at a preset angle. As long as the flipping device 1 and the front blocking device 2 are located on opposite sides of the conveyor line 3, and the flipping device 1 can act on the back side of the display device 4 while the front blocking device 2 can act on the side frame 42 of the display device 4, it is sufficient.

[0072] like Figures 3 to 5 As shown, the flipping device 1 includes a flipping mechanism, which includes a pushing unit 13 and a flipping drive member 15. The pushing unit 13 has a contacting member 132 for contacting the display device 4. The pushing unit 13 can slide along a first horizontal direction to make the contacting member 132 contact or separate from the display device 4. The flipping drive member 15 is used to drive the pushing unit 13 to rotate about an axis extending along a second horizontal direction.

[0073] By setting the pushing unit 13 to slide along the second horizontal direction, the movement of the pushing unit 13 ensures that before the flipping mechanism drives the display device 4 to flip, the pushing unit 13 can move horizontally to the position where the abutting part 132a contacts the display device 4. Then, the rotation of the pushing frame 131 can drive the display device 4 to rotate. That is, in the initial state, the flipping device 1 and the display device 4 are set separately, thereby avoiding the setting of the flipping device 1 from interfering with the transmission of the display device 4 on the conveyor line 3, and ensuring that the display device 4 can be transmitted to the correct position.

[0074] Furthermore, the flipping device 1 includes a frame 11 and an adjusting seat 12. The adjusting seat 12 is slidably mounted on the frame 11 along a first horizontal direction, and the pushing unit 13 is rotatably mounted on the adjusting seat 12 around a second horizontal direction. The flipping drive 15 is mounted on the adjusting seat 12 and connected to the pushing unit 13. The arrangement of the frame 11 and the adjusting seat 12, and the arrangement of the frame 11, can raise the height of the adjusting seat 12 and the flipping mechanism, thereby allowing the flipping mechanism to be better aligned with the display device 4 located on the conveyor line 3, and reducing the size of the flipping mechanism.

[0075] In other embodiments, the frame 11 may also be movable relative to the ground in a first horizontal direction, with a tilting mechanism rotatably mounted on the upper end of the frame 11. The frame 11 may also be self-driven or manually pushed by an operator.

[0076] The frame 11 includes a base plate 111, multiple support columns 113 vertically mounted on the base plate 111, and a top plate 112 connected to the upper ends of the support columns 113. Four support columns 113 are arranged in a rectangular pattern, thus simplifying the structure of the frame 11. The frame 11 also includes multiple legs 114 connected to the base plate 111. Preferably, four legs 114 are arranged in a rectangular pattern, and the height of the legs 114 is adjustable to fine-tune the height of the tilting mechanism.

[0077] It is worth noting that the structure of the frame 11 described above is an exemplary structure. Existing frame 11 structures that can realize the flipping mechanism and the adjustment seat 12 can be applied to this embodiment. This embodiment does not limit the structure of the frame 11.

[0078] In this embodiment, to achieve automatic movement of the adjusting seat 12, the flipping device 1 further includes a translation drive assembly 16, which drives the adjusting seat 12 to move along a first horizontal direction. In this embodiment, the translation drive assembly 16 includes a translation piston cylinder, which includes a fixed cylinder body and a piston rod. The fixed cylinder body is mounted on the top plate 112 of the frame, and the piston rod extends along the first horizontal direction and is connected to the adjusting seat 12. The extension and retraction of the telescopic rod 151 along the first horizontal direction can drive the adjusting seat 12 to move along the first horizontal direction.

[0079] In another embodiment, the translation drive assembly 16 may also employ other structures, such as a rotary motor, a lead screw connected to the drive shaft of the rotary motor, and a nut sleeved on the lead screw. The lead screw extends along a second horizontal direction and is rotatably mounted on the frame 11. The nut is connected to the adjusting seat 12, and a sliding limit structure is provided between the adjusting seat 12 and the frame 11 to limit the adjusting seat 12 to slide only along a first horizontal direction. In another embodiment, the translation drive assembly 16 may also employ a push rod motor, with the drive end of the push rod motor connected to the adjusting seat 12 to drive the adjusting seat 12 to move along the first horizontal direction. It is worth noting that other existing drive structures capable of translating the adjusting seat 12 can be applied to this embodiment, and this embodiment does not limit the specific structural form of the translation drive assembly 16.

[0080] Furthermore, the adjusting seat 12 includes a sliding plate 121 and a driving block 123 connected to the bottom of the sliding plate 121, the driving block 123 being connected to the piston rod. The sliding plate 121 is preferably spaced apart from the top plate 112, the translation drive assembly 16 is located between the sliding plate 121 and the top plate 112, and the flipping mechanism is installed on the upper side of the sliding plate 121 to provide space for the installation of the translation drive assembly 16 and to avoid interference between the translation drive assembly 16 and the flipping mechanism, thereby improving the rationality of the spatial layout.

[0081] It is understood that in other embodiments, the translation drive component 16 may not be provided, that is, the adjustment seat 12 may be moved by the operator manually pushing it.

[0082] To improve the reliability of the sliding of the adjusting seat 12, preferably, the flipping device 1 further includes a sliding guide assembly 17, which guides the sliding of the adjusting seat 12 along a first horizontal direction. In this embodiment, the sliding guide assembly 17 is installed between the sliding plate 121 and the top plate 112, and includes a guide rail 171 laid on the top plate 112 along the first horizontal direction and a guide shaft 172 slidably passing through the guide rail 171. The adjusting seat 12 also includes an adapter 122, which is connected to the guide shaft 172. In other embodiments, the sliding guide assembly 17 may include a slide rail extending along the first horizontal direction and a slider slidably disposed on the slide rail, one of which is connected to the top plate 112 and the other is connected to the sliding plate 121.

[0083] Furthermore, at least two adapter seats 122 are spaced apart along the length of the guide shaft 172 to improve guiding reliability and enhance the force balance and operational reliability of the adjusting seat 12 during sliding. Preferably, adapter seats 122 are provided at both ends of the guide shaft 172, and the two adapter seats 122 are respectively located at both ends of the sliding plate 121 along the first horizontal direction.

[0084] Preferably, the guide rail 171 is a linear bearing to reduce the friction between the guide rail 171 and the guide shaft 172. Two sliding guide assemblies 17 are preferably spaced apart along the first horizontal direction, and the translation drive assembly 16 is disposed between the two sliding guide assemblies 17 to further improve the force balance and sliding reliability of the adjusting seat 12.

[0085] To limit the sliding stroke of the adjusting seat 12, the flipping device 1 also includes a sliding limit component. In this embodiment, the sliding limit component includes a limit block 182 and a hydraulic buffer 181. When the adjusting seat 12 extends outward by a preset stroke, the limit block 182 abuts against the hydraulic buffer 181 to limit the adjusting seat 12 from sliding forward. At the same time, the hydraulic buffer 181 can provide cushioning when in contact with the limit block 182, reducing vibration during contact. It is worth noting that the structure of the above-mentioned sliding limit component is only an exemplary structure. Other existing structures that can achieve sliding limit can be applied to this embodiment. For example, the sliding limit component can use an elastic pad to contact the limit block 182 to achieve limiting and cushioning. This embodiment does not specifically limit the specific form of the sliding limit component.

[0086] Furthermore, the flipping device 1 also includes baffles 19, one of which is provided on each side of the sliding plate 121 along the second horizontal direction. The baffles 19 are used to block the lateral gap between the sliding plate 121 and the top plate 112, so that the sliding guide assembly 17 and the translation drive assembly 16 can be located between the two baffles 19. This reduces the probability of dust, impurities, etc. acting on the sliding guide assembly 17 and the translation drive assembly 16, improves the smoothness and reliability of the operation of the translation drive assembly 16 and the sliding guide assembly 17, and enhances the aesthetic appearance of the flipping device 1. The baffles 19 are detachably connected to the sliding plate 121 or the top plate 112.

[0087] In this embodiment, the baffle plate 19 is detachably connected to the top plate 112, thereby reducing the load on the translation drive assembly 16. The baffle plate 19 includes a baffle portion, which is perpendicular to the second horizontal direction and connected to the top plate 112 at its lower end. The baffle portion has side flanges folded inward on both sides along the first horizontal direction, and the upper end of the baffle portion is folded inward to form an upper flange. The sliding plate 121 is located below the upper flange. An extension plate portion is also provided on the lower side of the baffle portion, and the extension plate portion is detachably connected to the support column 113 to ensure the reliability of the installation of the baffle plate 19 on the frame 11.

[0088] like Figure 3 and Figure 5 As shown, the pushing unit 13 includes a pushing frame 131. The lower end of the pushing frame 131 is rotatably mounted on the adjusting seat 12 via a mounting shaft 133. The abutting component 132 is detachably mounted on the pushing frame 131 and protrudes from the pushing frame 131 towards the front blocking device 2. By setting the pushing frame 131 and the abutting component 132 to be detachably connected, the pushing frame 131 and the abutting component 132 can be made of different materials, improving the flexibility of the pushing unit 13 and making it easier to replace the abutting component 132 after it is worn or damaged, thus improving the convenience of replacing the abutting component 132. At the same time, since the abutting component 132 protrudes from the pushing frame 131 towards the front blocking device 2, when the abutting component 132 abuts against the back of the display device 4, the pushing frame 131 will not contact the display device 4, avoiding the pushing frame 131 from scratching the display device 4.

[0089] Furthermore, the adjusting seat 12 includes two hinge seats 124 that are opposite to each other and spaced apart along the second horizontal direction. The two hinge seats 124 are mounted on the upper end face of the sliding plate 121. The two ends of the mounting shaft 133 are mounted on the two hinge seats 124. The pusher 131 is located between the two hinge seats 124.

[0090] The abutting component 132 includes a lower abutting component 132a and an upper abutting component 132b. The lower abutting component 132a is sleeved on the mounting shaft 133, and the upper abutting component 132b is mounted on the top of the pusher frame 131. In the first horizontal direction, the distance between the lower abutting component 132a and the front blocking device 2 is smaller than the distance between the upper abutting component 132b and the front blocking device 2.

[0091] The upper abutting component 132b and the lower abutting component 132a are configured such that when the flipping mechanism drives the display device 4 to rotate, both the upper abutting component 132b and the lower abutting component 132a are in contact with the back of the display device 4. This ensures that the flipping device 1 has at least two contact positions with the back of the display device 4 in the height direction of the display device 4, thereby improving the force balance and flipping stability of the display device 4 during the flipping process. At the same time, the lower abutting component 132a is sleeved on the mounting shaft 133, so that the lower abutting component 132a always remains in contact with the display device 4 during the rotation of the pusher 131. This effectively prevents the display device 4 from sliding during the flipping process, thereby improving the flipping reliability and stability of the display device 4.

[0092] The lower abutment member 132a is preferably made of an elastic material, which may be, but is not limited to, silicone or rubber, to avoid hard collisions between the lower abutment member 132a and the display device 4, reducing the probability of the display device 4 being crushed and damaged. The lower abutment member 132a is preferably rotatably sleeved on the mounting shaft 133, so that the friction between the lower abutment member 132a and the back of the display device 4 is rolling friction, reducing the wear of the lower abutment member 132a on the display device 4.

[0093] The upper abutment member 132b is preferably made of an elastic material to avoid damage to the display device 4 caused by a hard collision between the upper abutment member 132b and the back of the display device 4. Preferably, the upper abutment member 132b is a sleeve-shaped, roller, or axle structure, and the extending direction of the upper abutment member 132b is the same as the extending direction of the mounting shaft 133, so as to simplify the structure of the upper abutment member 132b and improve the ease of installation of the upper abutment member 132b on the pusher frame 131. In other embodiments, the upper abutment member 132b may also be a strip-shaped structure or a block-shaped structure, etc.

[0094] Since the position of the upper abutment member 132b relative to the display device 4 changes when the pusher frame 131 drives the display device 4 to rotate, in order to reduce the friction between the upper abutment member 132b and the display device 4, preferably, the upper abutment member 132b is rotatably mounted on the pusher frame 131 around its own axis, and the axis of rotation of the upper abutment member 132b is set along the second horizontal direction. Therefore, when the upper abutment member 132b pushes the display device 4 to rotate, the frictional force between the upper abutment member 132b and the display device 4 is rolling friction, reducing the frictional force and effectively avoiding the problem of wear on the display device 4 caused by excessive frictional force applied by the upper abutment member 132b.

[0095] Preferably, the plane containing the center lines of the upper abutting member 132b and the lower abutting member 132a is spaced apart from the pusher frame 131, and the pusher frame 131 is located on the side of the plane away from the front blocking device 2. This ensures that when the upper abutting member 132b rotates to contact the display device 4, only the upper abutting member 132b and the lower abutting member 132a abut against the display device 4, while the pusher frame 131 is spaced apart from the display device 4. This ensures the stability of the flipping mechanism in supporting the display device 4, while avoiding the problem that the upper abutting member 132b or the lower abutting member 132a may not be able to contact the display device 4 due to the contact between the pusher frame 131 and the display device 4. This ensures the reliability of the contact between the upper abutting member 132b and the lower abutting member 132a and the display device 4, and reduces the processing accuracy requirements of the pusher frame 131.

[0096] To improve the ease of installation of the upper abutting component 132b and the lower abutting component 132a, preferably, the pusher frame 131 includes two swing arms 1311 that are opposite to each other and spaced apart along a first horizontal direction. A mounting shaft 133 rotatably passes through the lower ends of the two swing arms 1311, and the upper abutting component 132b is connected between the upper ends of the two swing arms 1311. Specifically, a connecting shaft 1314 connects the upper ends of the two swing arms 1311, and the upper abutting component 132b is rotatably sleeved on the connecting shaft 1314. This arrangement simplifies the structure of the pusher frame 131, reduces its weight, and facilitates the installation of the mounting shaft 133 and the connecting shaft 1314 while ensuring the structural strength and rigidity of the pusher frame 131.

[0097] The swing arm 1311 preferably includes a first arm 13111 and a second arm 13112. The first arm 13111 extends obliquely from bottom to top away from the front blocking device 2. The lower end of the second arm 13112 is connected to the upper end of the first arm 13111. The second arm 13112 extends vertically from bottom to top or is obliquely from bottom to top towards the front blocking device 2. The second arm 13112 and the first arm 13111 are set at a preset obtuse angle. The connecting shaft 1314 is installed at the upper end of the second arm 13112. This configuration allows for a reduction in the distance between the upper abutting component 132b and the lower abutting component 132a in the first horizontal direction, while maintaining the vertical distance between them. This reduces the required rotation angle of the pusher frame 131 when the upper abutting component 132b rotates from its initial state to abut against the display device 4, thereby improving driving efficiency. Simultaneously, this configuration increases the angle between the plane containing the central axis of the mounting shaft 133 and the connecting shaft 1314 and the plane containing the two first arm portions 13111, effectively preventing the pusher frame 131 from contacting the display device 4.

[0098] To better ensure the overall structural rigidity of the pusher frame 131, a connecting rod 1313 is also connected between the two swing arms 1311. The connecting rod 1313 is spaced apart from the connecting shaft 1314 and the mounting shaft 133, thereby improving the overall integrity of the pusher frame 131 and reducing the probability of deformation of the two swing arms 1311. In this embodiment, there is one connecting rod 1313 that extends along the extension direction of the mounting shaft 133. In other embodiments, there may be two or more connecting rods 1313 spaced apart along the extension direction of the swing arms 1311.

[0099] The pusher frame 131 also includes a connecting plate 1312, which is connected between the two swing arms 1311. The lower end of the connecting plate 1312 extends to the lower abutment member 132a, and the upper end of the connecting plate 1312 extends to near the second arm 13112. The connection plate 1312 further improves the structural integrity and rigidity of the pusher frame 131, and can shield the structure on the side of the connecting plate 1312 away from the front blocking device 2, preventing the structure on the conveyor line 3 from bumping into the tilting drive 15, thereby improving the safety and reliability of the tilting drive 15.

[0100] The flipping drive 15 preferably includes a piston cylinder, which includes a cylinder body and a telescopic rod 151 that can extend and retract relative to the cylinder body. The fixed end of the cylinder body is hinged to the adjusting seat 12, and the end of the telescopic rod 151 is hinged to the pusher frame 131. The piston cylinder extends from bottom to top in the direction toward the pusher frame 131. Thus, when the telescopic rod 151 extends, it pushes the pusher frame 131 to rotate in the direction toward the front blocking device 2, so that the upper abutting member 132b can rotate in the direction closer to the display device 4 to contact the display device 4. After the upper abutting member 132b contacts the display device 4, the continued rotation of the pusher frame 131 synchronously drives the display device 4 to rotate. When the telescopic rod 151 retracts, it drives the pusher frame 131 to rotate and return to its initial state on the side away from the front blocking device 2.

[0101] In this embodiment, the telescopic rod 151 is hinged to the connecting rod 1313, and the axis of the hinge is the axis of the connecting rod 1313, which simplifies the connection structure between the flipping drive component 15 and the pusher frame 131 and improves assembly convenience. Furthermore, a bearing component 152 is rotatably sleeved on the connecting rod 1313, and the bearing component 152 is connected to the telescopic rod 151. The bearing component 152 is a spherical plain bearing, a fisheye bearing, or a universal ball bearing, etc., to improve the connection convenience between the bearing component 152 and the telescopic rod 151. Furthermore, a clearance opening is provided on the connecting plate 1312, and the bearing component 152 is positioned directly opposite the clearance opening to avoid interference between the bearing component 152 and the connecting plate 1312.

[0102] like Figure 5 and Figure 6 As shown, preferably, the flipping device 1 further includes a rotation limiting component 14, which is used to limit the rotation angle of the pushing unit 13, thereby ensuring the flipping reliability and safety of the display device 4.

[0103] In this embodiment, the rotation limiting assembly 14 includes a limiting seat 141, a limiting rod 142, and a limiting shaft 143. The limiting seat 141 is mounted on the adjusting seat 12 and is located on the side of the pushing unit 13 away from the front blocking device 2. The limiting seat 141 has a limiting groove 1411 extending along the second horizontal direction. The limiting rod 142 is inclined from bottom to top towards the front blocking device 2, and the upper end of the limiting rod 142 is hinged to the pushing unit 13. The limiting shaft 143 is connected to the lower end of the limiting rod 142 and is slidably inserted into the limiting groove 1411.

[0104] As described above, when the pusher 131 flips towards the front blocking device 2, the lower end of the limiting rod 142 moves away from the limiting seat 141 along with the pusher 131. This causes the lower end of the limiting rod 142 and the limiting shaft 143 to slide towards the front blocking device 2. That is, the limiting shaft 143 slides in the limiting groove 1411. When the limiting shaft 143 slides to abut against the groove end wall of the limiting groove 1411, the limiting rod 142 can no longer move relative to the limiting seat 141. That is, the pusher 131 can no longer rotate towards the front blocking device 2, thus limiting the maximum tilt angle of the pusher 131. Similarly, when the limiting shaft 143 abuts against the groove end wall of the limiting groove 1411 away from the mounting shaft 133, the pusher 131 has the minimum tilt angle relative to the adjusting seat 12.

[0105] That is, the structure of the aforementioned rotation limiting component 14 can limit the rotation stroke of the pusher 131 by the length of the limiting groove 1411; at the same time, the structure of the aforementioned rotation limiting component 14 is such that the structure of the rotation limiting component 14 is located on the side of the connecting plate 1312 away from the front blocking device 2, which can prevent the rotation limiting component 14 from colliding with the display device 4, and improve the rationality and convenience of the layout of the rotation limiting component 14; furthermore, the aforementioned rotation limiting component 14 can also support the pusher 131, increase the stability and reliability of the force on the pusher 131 during rotation, and improve the structural stability of the pusher 131.

[0106] In other embodiments, other structures that limit the rotational stroke of the pusher 131 can be provided. For example, an arc-shaped limiting groove can be provided on the hinge seat 124, and a limiting protrusion can be provided on the swing arm 1311. The limiting protrusion is slidably inserted into the limiting arc groove, thereby realizing the rotational limitation of the swing arm 1311 relative to the hinge seat 124, that is, realizing the rotational limitation of the pusher 131.

[0107] The limiting rod 142 preferably includes a rod body 1421 and hinge members 1422 connected to both ends of the rod body 1421. The hinge members 1422 are bearing structures. One hinge member 1422 has a hinge shaft 144 inserted into its inner ring, and the other hinge member 1422 has the aforementioned limiting shaft 143 inserted into its inner ring. Both the hinge shaft 144 and the limiting shaft 143 extend along a second horizontal direction. The hinge shaft 144 is mounted on the pusher frame 131. This structure of the limiting rod 142 facilitates the hinge connection between the limiting rod 142 and the limiting shaft 143 and the pusher frame 131, and improves the smoothness of the rotation of the limiting rod 142 relative to the pusher frame 131 and the smoothness of its sliding relative to the limiting seat 141.

[0108] Preferably, two rotation limiting components 14 are provided, each corresponding to one of the two swing arms 1311, to improve the force balance and rotational reliability of the push frame 131 during rotation. Simultaneously, the two rotation limiting components 14 can support the two swing arms 1311, enhancing the structural stability of the push frame 131 during rotation. Furthermore, a mounting cavity is formed on the side of the swing arm 1311 facing away from the connecting plate 1312, and the hinge shaft 144 is connected to the two side walls of the mounting cavity, thereby improving the ease of installation of the hinge shaft 144 on the push frame 131.

[0109] Preferably, the hinge 1422 includes a bearing portion and a rod portion connected to the outer wall of the bearing portion. The bearing portion is connected to the hinge shaft 144 or the limiting shaft 143. The rod portion extends coaxially with the rod body 1421 and is threadedly connected. This allows the total length of the limiting rod 142 to be adjusted, thereby adjusting the minimum and maximum tilt angles of the pushing unit 13 while keeping the groove length of the limiting groove 1411 unchanged. This improves the applicability of the rotation limiting assembly 14.

[0110] The limiting seat 141 has an upper-opening mounting groove. Limiting grooves 1411 are formed on the opposite sides of the mounting groove in the second horizontal direction. The lower end of the corresponding hinge member 1422 extends out of the mounting groove. Both ends of the limiting shaft 143 are slidably disposed in the two limiting grooves 1411, thereby improving the reliability of the fit between the limiting shaft 143 and the limiting grooves 1411. The limiting shaft 143 preferably includes a main shaft portion and an anti-detachment portion. The main shaft portion passes through the two limiting grooves 1411. The end of the main shaft portion away from the anti-detachment portion is detachably connected to a limiting member. Both the anti-detachment portion and the limiting member are located outside the limiting seat 141 and are restricted from passing through the limiting grooves 1411. This improves the ease of assembly of the limiting shaft 143 with the limiting seat 141 and the bearing member 152.

[0111] Furthermore, such as Figure 3 As shown, the flipping device 1 also includes two opposing and spaced-apart side baffles 110. The two side baffles 110 are located on opposite sides of the pusher frame 131 along the second horizontal direction, and the two side baffles 110 and the pusher frame 131 together form a shielding space. The shielding space is located on the side of the pusher unit 13 away from the front blocking device 2. The rotation limiting component 14 is located in the shielding space, and the flipping drive component 15 is at least partially located in the shielding space. This allows the two side baffles 110 to laterally shield the flipping drive component 15 and the rotation limiting component 14, improving the aesthetic appearance of the flipping device 1 and improving the reliability of the flipping device 1.

[0112] The side baffle 110 includes a side plate portion, the lower end of which is bent into a lower folded edge portion. The lower folded plate portion is fitted to and detachably connected to the sliding plate 121. The side plate portion has an inclined side extending from top to bottom away from the conveyor line 3, and the inclined side is folded inward into a front folded edge portion. When the flipping device 1 is in the initial state, the front folded edge portion is parallel to the connecting plate 1312 to improve the overall aesthetic appearance of the flipping device 1.

[0113] like Figure 7 and Figure 8 As shown, the aforementioned front blocking device 2 also includes a mounting bracket 21. The stopping mechanism includes a sliding bracket 22 and a stopping assembly 23. The sliding bracket 22 is slidably mounted on the mounting bracket 21 along a second horizontal direction. The stopping assembly 23 is mounted on the sliding bracket 22 and located above the mounting bracket 21. The stopping assembly 23 is used to abut against the frame of the display device 4. Thus, by sliding the sliding bracket 22 relative to the mounting bracket 21 along the second horizontal direction, the position of the stopping assembly 23 in the second horizontal direction can be adjusted, allowing the stopping assembly 23 to be aligned with the frame of the display device 4. This enables the stand-up camera to be used with display devices 4 of different models and sizes, improving the versatility of the stand-up camera and reducing its operating costs.

[0114] In this embodiment, the mounting bracket 21 includes two mounting side plates 212 that are arranged opposite to each other and spaced apart in the second horizontal direction, and a mounting main plate 211 connected between the bottom ends of the two mounting side plates 212. The mounting main plate 211 is perpendicular to the first horizontal direction, and a stop mechanism is slidably mounted on the mounting main plate 211. A reinforcing plate 216 is preferably connected between the mounting main plate 211 and the two mounting side plates 212 to reduce the probability of deformation of the mounting main plate 211.

[0115] Mounting bracket 21 also includes mounting base plate 213 connected between the bottom ends of the two mounting side plates 212. Mounting main plate 211 and mounting base plate 213 are spaced apart so that mounting main plate 211, mounting base plate 213 and the two mounting side plates 212 surround and form an installation space. Front blocking device 2 also includes stop controller 210, which is installed in the installation space to avoid interference between stop controller 210 and stop mechanism.

[0116] Mounting bracket 21 also includes a mounting back plate 214, which is connected between the two mounting side plates 212 and its lower end is connected to the mounting base plate 213. The mounting back plate 214 is located on the side of the stop controller 210 away from the flipping mechanism to provide shielding and protection for the stop controller 210. The mounting back plate 214 and the mounting main plate 211 are spaced apart in the first horizontal direction, and the side of the mounting side plate 212 away from the flipping device 1 is flush with the mounting back plate 214 to prevent the structure mounted on the mounting main plate 211 from being collided with by external structures, thereby improving the safety of the front blocking device 2.

[0117] To improve the reliability and stability of the docking between the front blocking device 2 and the conveyor line 3, a docking fixing seat 215 is connected to the side of the mounting main board 211 facing the flipping device 1. Two docking fixing seats 215 are spaced apart along the second horizontal direction. One end of the docking fixing seat 215 is connected to the mounting main board 211, and the other end is used to connect to the conveyor line 3.

[0118] To improve the reliability and smoothness of the stopping mechanism sliding along the second horizontal direction, the front blocking device 2 further includes a sliding guide assembly 25. In this embodiment, the sliding guide assembly 25 includes a guide rail 251 mounted on the mounting main board 211 along the second horizontal direction and a guide slider 252 slidably disposed on the guide rail 251, the guide slider 252 being connected to the sliding frame 22. In other embodiments, the sliding guide assembly 25 may also employ other existing structures capable of achieving sliding guidance, such as a structure with a linear bearing and a guide rod, etc. The present invention does not limit the structure of the sliding guide assembly 25. Preferably, two sliding guide assemblies 25 are spaced apart along the vertical direction to improve the force stability and operational reliability of the stopping mechanism.

[0119] To enable the automatic sliding of the stop mechanism along the second horizontal direction, the front blocking device 2 further includes a sliding drive assembly 24, which drives the stop mechanism to slide along the second horizontal direction. Preferably, the sliding guide assembly 25 and the sliding drive assembly 24 are located on opposite sides of the mounting motherboard 211 to improve the rationality of the spatial layout and reduce the probability of interference between the structures. In this embodiment, the sliding guide assembly 25 is located on the side of the mounting motherboard 211 away from the flipping device 1. In other embodiments, the sliding drive assembly 24 may also be located on the side of the mounting motherboard 211 away from the flipping device 1.

[0120] The sliding bracket 22 is positioned on the side of the mounting motherboard 211 away from the sliding drive assembly 24 to reduce the probability of interference between the sliding bracket 22 and the display device 4 and the conveyor line 3, and to provide sufficient space for the arrangement of the sliding drive assembly 24. To improve the ease of connection between the sliding bracket 22 and the sliding drive assembly 24, the mounting motherboard 211 has an elongated opening 2111 extending along a first horizontal direction. The sliding bracket 22 has a drive connector 224, which passes through the elongated opening 2111 and connects to the sliding drive assembly 24. Preferably, two sliding guide assemblies 25 are located on the upper and lower sides of the elongated opening 2111, respectively.

[0121] like Figure 8 and Figure 9As shown, in this embodiment, the sliding drive assembly 24 includes a drive motor 241, a transmission screw 242, and a nut seat 243. The transmission screw 242 extends along a second horizontal direction and is rotatably mounted on the mounting plate 211. The drive motor 241 drives the transmission screw 242 to rotate. The nut seat 243 is threaded onto the transmission screw 242 and is connected to the drive connector 224. Thus, when the drive motor 241 drives the transmission screw 242 to rotate, the nut seat 243 moves along the extension direction of the transmission screw 242, thereby driving the stop mechanism to move along the second horizontal direction.

[0122] Furthermore, the mounting motherboard 211 is provided with at least two bearing seats spaced apart along the second horizontal direction, and the transmission screw 242 rotatably passes through the bearing seats. The transmission screw 242 includes a screw section and a shaft section coaxially connected to both ends of the screw section. Two bearing seats are provided, and the two shaft sections rotatably pass through the two bearing seats. Preferably, a rotary bearing is provided between the shaft section and the rotating shaft.

[0123] The sliding drive assembly 24 also includes a transmission assembly 244, which is connected between the lead screw 242 and the drive motor 241 to transmit the driving force of the drive motor 241 to the lead screw 242. This reduces the requirements for the installation position of the drive motor 241 and improves the ease of layout of the drive motor 241 on the mounting bracket 21. In other embodiments, the drive shaft of the drive motor 241 can also be directly connected to one end of the lead screw 242.

[0124] In this embodiment, the transmission assembly 244 further includes a driving pulley 2441 sleeved on the drive shaft of the drive motor 241, a driven pulley 2442 sleeved on a shaft section, and a transmission belt 2443 wound around the driving pulley 2441 and the driven pulley 2442. That is, the transmission assembly 244 adopts belt drive. In other embodiments, the transmission assembly 244 may also adopt a gear drive or chain drive structure. Both gear drive and chain drive structures are conventional transmission structures and will not be described in detail here.

[0125] like Figures 8 to 10 As shown, to better control the travel of the stop mechanism, in this embodiment, the front blocking device 2 further includes a position detection component 26. The position detection component 26 is used to detect the position of the stop mechanism relative to the mounting bracket 21 in the second horizontal direction. In this embodiment, the position detection component 26 includes a position sensor 261 and a sensing element 262 that work together. One of the position sensor 261 and the sensing element 262 is mounted on the sliding bracket 22 of the stop mechanism, and the other is mounted on the mounting main board 211. The position sensor 261 can be triggered by the sensing element 262 when it approaches or abuts against the sensing element 262, thereby realizing the position detection of the stop mechanism.

[0126] In this embodiment, the position sensor 261 is mounted on the mounting motherboard 211, and the sensing element 262 is mounted on the stop mechanism. Preferably, the position sensor 261 is located on the side of the mounting motherboard 211 away from the sliding frame 22 to avoid interference between the position sensor 261 and the sliding frame 22, and the sensing element 262 is mounted on the drive connector 224.

[0127] At least two position sensors 261 are spaced apart along the second horizontal direction, meaning the position detection assembly 26 includes at least two extreme position sensors 261a. These two extreme position sensors 261a are used to detect the two extreme positions that the stopping mechanism can reach, i.e., the sliding drive assembly 24 drives the stopping mechanism to move between these two extreme positions. In this embodiment, three position sensors 261 are provided; the other position sensor 261 is an origin position sensor 261b, located between the two extreme position sensors 261a, used to detect whether the stopping mechanism has returned to its initial position. The origin position sensor 261b is positioned close to an extreme position sensor 261a that is farther away from the other stopping mechanism.

[0128] In this embodiment, the position sensor 261 is preferably a U-shaped photoelectric sensor. The U-shaped photoelectric sensor has a U-shaped detection groove, the opening of which faces the sensing element 262, and the detection groove extends through the sensor in a second horizontal direction. The sensing element 262 can slide into the detection groove with the stop mechanism to block light from entering the detection groove, thereby changing the output signal of the position sensor 261. In other embodiments, the position sensor 261 can also be a proximity switch or a micro switch.

[0129] Furthermore, to enhance the applicability of the front blocking device 2 to display devices 4 of different sizes, the positions of all position sensors 261 relative to the mounting motherboard 211 in the second horizontal direction can be adjusted. This allows the travel of the stop mechanism in the second horizontal direction to be adjusted by adjusting the distance between the two limit position sensors 261a. Moreover, by adjusting the distance between the origin position sensor 261b and the adjacent limit position sensor 261a, it can be ensured that when the display device 4 is transported to its position by the conveyor line 3, the stop device in its initial state can be located outside the display device 4 in the second horizontal direction.

[0130] The position detection assembly 26 also includes a slide 264 and a sensor mount 263. The slide 264 extends along a second horizontal direction and is mounted on the mounting motherboard 211. Each position sensor 261 is mounted on the slide 264 via the sensor mount 263. The mounting position of the sensor mount 263 on the slide 264 is adjustable in the second horizontal direction, thereby adjusting the position of the position sensor 261 by adjusting the position of the sensor mount 263. Furthermore, a mounting groove 2641 is formed on the slide 264 along the second horizontal direction. The sensor mount 263 is connected to the slide 264 by fasteners, which are slidably disposed in the mounting groove 2641, thereby improving the convenience of adjusting the position of the sensor mount 263.

[0131] like Figure 7 and Figure 8 As shown, the sliding frame 22 includes a sliding plate 221 and a sliding rod 222. The sliding plate 221 is opposite to and spaced apart from the mounting plate 211, and is slidably mounted on the mounting plate 211. Specifically, the sliding plate 221 is connected to the guide sliders 252 of the two sliding guide assemblies 25. The sliding rod 222 extends from bottom to top, and its lower end is connected to the sliding plate 221. A stop assembly 23 is mounted on the sliding rod 222 and located above the mounting frame 21. The width of the sliding rod 222 in the second horizontal direction is smaller than the width of the sliding plate 221 in the second horizontal direction. By setting the sliding rod 222 and the sliding plate 221, the convenience of sliding connection between the sliding frame 22 and the mounting frame 21 can be improved. At the same time, the overall size and weight of the sliding frame 22 can be reduced, thus lowering the cost.

[0132] The drive connector 224 is vertically connected to the slide plate 221, and the slide rod 222 is connected to the side of the slide plate 221 away from the slide drive assembly 24 to increase the contact area between the slide rod 222 and the slide plate 221. The slide rod 222 and the slide plate 221 are preferably detachably connected by screws, but in other embodiments, the slide rod 222 and the slide plate 221 may also be welded.

[0133] The sliding rod 222 includes a lower rod section 2221, an inclined rod section 2222, and an upper rod section 2223 connected sequentially from bottom to top. Both the lower rod section 2221 and the upper rod section 2223 are vertically arranged. The lower rod section 2221 is connected to the sliding plate 221. A stop assembly 23 is installed on the upper rod section 2223. The inclined rod section 2222 is inclined from bottom to top toward the display device 4. This allows the lower rod section 2221 to be installed on the side of the mounting bracket 21 away from the display device 4, while shortening the distance between the upper rod section 2223 and the conveyor line 3. This reduces the distance between the stop assembly 23 and the conveyor line 3, improving the ease of setting the stop assembly 23.

[0134] like Figure 7 , Figure 8and Figure 11 As shown, the stop assembly 23 includes a stop member 232 and a stop drive member 231. The stop drive member 231 drives the stop member 232 to move along a first horizontal direction, so that the stop member 232 abuts against or separates from the display device 4. This allows the stop member 232 to extend relative to the sliding frame 22 to contact the side frame 42 of the display device 4 when it is necessary to abut against the display device 4. This avoids the need for the sliding frame 22 to move as a whole along the first horizontal direction to achieve docking or separation with the display device 4, reducing the driving load on the stop drive member 231, saving costs, and making it easier to control the movement stroke of the stop member 232 along the first horizontal direction.

[0135] In this embodiment, the stop assembly 23 further includes a connecting seat 233. The stop member 232 is a sleeve, roller, or wheel structure, and the axis of the stop member 232 is arranged along a second horizontal direction. The stop member 232 is rotatably mounted on the connecting seat 233 around its own axis. The stop drive member 231 is connected to the connecting seat 233. Thus, when the stop member 232 contacts the side frame 42 of the display device 4, the friction between the stop member 232 and the side frame 42 is rolling friction, reducing the friction and lowering the probability of wear on the display device 4 caused by the stop member 232. The stop member 232 is preferably made of an elastic material to avoid hard contact between the stop member 232 and the display device 4, thereby improving the safety of stopping the display device 4.

[0136] Furthermore, the stop assembly 23 includes a floating assembly 234, and the stop member 232 can be floatingly mounted on the connecting seat 233 along the first horizontal direction through the floating assembly 234, thereby making the side frame 42 and the stop member 232 in elastic contact, further avoiding hard collisions between the stop member 232 and the side frame 42, and buffering the impact generated when the stop member 232 and the side frame 42 just come into contact, thereby improving the safety and reliability of the display device 4 when flipping.

[0137] The floating assembly 234 includes a floating guide rod 2341, an elastic element 2342, and a support 2343. The floating guide rod 2341 is slidably inserted into the connecting seat 233 along the first horizontal direction. The end of the floating guide rod 2341 facing the flipping device 1 is connected to the support 2343. The elastic element 2342 is sleeved on the floating guide rod 2341. Both ends of the elastic element 2342 abut against the support 2343 and the connecting seat 233. The stop 232 is installed on the support 2343. The structure of this floating component 234 can guide the floating of the stop 232 through the floating guide rod 2341, improving the reliability and smoothness of the floating of the stop 232. At the same time, the setting of the elastic element 2342 is conducive to realizing the reset of the stop 232 after being pressed and floating, improving the continuity of use of the front blocking device 2. Meanwhile, when the side frame 42 of the display device 4 presses against the stop 232, the elastic element 2342 is in a compressed state, and the elastic element 2342 applies an elastic force toward the display device 4 to the support 2343, thereby ensuring that the stop 232 can be reliably pressed against the side frame 42, effectively ensuring the blocking effect of the stop component 23 on the display device 4.

[0138] Furthermore, the floating assembly 234 also includes a guide sleeve 2344, which is fixedly inserted into the connecting seat 233 and extends along the first horizontal direction. The floating guide rod 2341 is slidably inserted into the guide sleeve 2344, thereby reducing wear on the connecting seat 233 and ensuring the reliability of the floating guide rod 2341. The guide sleeve 2344 is preferably made of a wear-resistant material.

[0139] Preferably, two floating guide rods 2341 are spaced apart. Guide sleeves 2344 and elastic elements 2342 are each corresponding to a floating guide rod 2341. All floating guide rods 2341 are connected to supports 2343 and connecting seats 233 to ensure the force balance and floating reliability of supports 2343 and stop elements 232. In this embodiment, two floating guide rods 2341 are spaced apart vertically.

[0140] The stop drive component 231 preferably includes a stop piston cylinder, the cylinder body of which is mounted on the sliding rod 222, and the piston rod end of the stop piston cylinder is connected to the connecting seat 233. The stop piston cylinder is preferably a pneumatic cylinder, which is small in size, lightweight, and easy to install. In other embodiments, other existing structures capable of linear drive can also be used, such as hydraulic cylinders, push rod motors, wax motors, linear motors, or other structures.

[0141] The stop components 23 are preferably provided in multiple intervals along the extension direction of the sliding frame 22 to increase the contact position between the front blocking device 2 and the side frame 42 of the display device 4, improve the stopping effect on the display device 4, and at the same time reduce the size of each stop component 23. In this embodiment, the stop components 23 are provided in multiple intervals along the extension direction (i.e., the vertical direction) of the upper rod segment 2223.

[0142] It is understandable that when the preset angle is 90°, the display device 4 is set vertically, and the distance between the multiple stop members 232 and the sliding rod 222 is the same, that is, the multiple stop members 232 are set at intervals in the vertical direction to achieve multi-point support for the display device 4; if the display device 4 is flipped to the preset angle, when the display device 4 is tilted relative to the vertical plane, the distance that each stop member 232 extends relative to the sliding rod 222 is different, so as to ensure that each stop member 232 is in contact with the display device 4.

[0143] To achieve automatic alignment between the stop assembly 23 and the frame of the display device 4, in this embodiment, the front blocking device 2 further includes an edge-finding sensor 28. The edge-finding sensor 28 is used to detect the position of the side edge of the display device 4. The edge-finding sensor 28 is communicatively connected to the stop controller 210. The stop controller 210 controls the sliding drive assembly 24 to move according to the side edge position detected by the edge-finding sensor 28.

[0144] In this embodiment, when the display device 4 is transported to its position by the conveyor line 3, the two stop mechanisms are located on the outer sides of the display device 4 along the second horizontal direction, with the stop mechanisms positioned at the origin relative to the mounting bracket 21. When the sliding drive assembly 24 drives the stop mechanisms to slide along the second horizontal direction, the edge-finding sensor 28 performs detection. When the edge-finding sensor 28 is misaligned with the display device 4 in the second horizontal direction, the edge-finding sensor 28 does not output a signal. When the edge-finding sensor 28 is aligned with the display device 4 in the second horizontal direction, the edge-finding sensor outputs a signal. That is, when the edge-finding sensor 28 switches from a state of no output signal to a state of output signal, it indicates that the edge of the display device 4 has been detected.

[0145] The front blocking device 2 also includes a repeater sensor 29, which is mounted on the sliding frame 22 and located on the side of the edge-finding sensor 28 facing the other blocking mechanism. The repeater sensor 29 is used to detect whether the display device 4 is present on the front side of the blocking mechanism, and it is communicatively connected to the blocking controller 210. By setting the repeater sensor 29, when both the repeater sensor 29 and the edge-finding sensor 28 detect the display device 4, it is determined that the display device 4 is present on the front side of the blocking mechanism. This improves detection reliability, avoids false judgments caused by the failure of the edge-finding sensor 28, reduces the probability of false judgments, and thus improves the operational reliability and safety of the front blocking device 2.

[0146] Furthermore, the front blocking device 2 also includes a backup sensor 230, which is mounted on the sliding frame 22 and is used to detect the side edge of the display device 4. The backup sensor 230 is a spare component of the edge-finding sensor 28, and is activated in case the edge-finding sensor 28 fails or malfunctions.

[0147] The repeater sensor 29, the edge-finding sensor 28, and the backup sensor 230 are preferably all reflective photoelectric sensors to achieve non-contact detection. This ensures detection reliability while reducing the installation location requirements for the repeater sensor 29, the edge-finding sensor 28, and the backup sensor 230. In other embodiments, the repeater sensor 29, the edge-finding sensor 28, and / or the backup sensor 230 may also be microswitches or other existing sensors capable of position detection.

[0148] To prevent the stop assembly 23 from failing to contact the side frame 42 due to misalignment with the side frame 42 of the display device 4, thereby causing the display device 4 to tip over in a direction away from the flipping mechanism, preferably, the front blocking device 2 further includes an anti-tilt member 27. The anti-tilt member 27 is mounted on the sliding rod 222 and located on the side of the stop assembly 23 facing the other stop mechanism. In the first horizontal direction, the distance between the anti-tilt member 27 and the sliding rod 222 is smaller than the distance between the stop member 232 and the sliding rod 222, and the anti-tilt member 27 extends in the second horizontal direction.

[0149] By setting the anti-tilt component 27, when the stop component 232 is in normal contact with the side frame 42 of the display device 4, the anti-tilt component 27 is closer to the sliding rod 222 than the stop component 232. The anti-tilt component 27 is spaced apart from the display device 4, which avoids the anti-tilt component 27 from contacting the display device 4 when the stop component 23 is in normal stopping state. When the stop component 232 is facing the outside of the side frame 42, if the display device 4 flips along the side away from the flipping device 1, the anti-tilt component 27 can contact the display device 4 to prevent the display device 4 from continuing to tilt, thereby improving the rotation safety and reliability of the display device 4.

[0150] The anti-tilt component 27 is rotatable around its own axis and mounted on the sliding frame 22, thereby making the friction between the anti-tilt component 27 and the display device 4 rolling friction, avoiding scratches to the display device 4. The anti-tilt component 27 is preferably made of an elastic material such as rubber or silicone. Preferably, at least two anti-tilt components 27 are spaced apart in the vertical direction to increase the contact points with the display device 4 and improve the reliability of preventing the display device 4 from tipping over. The anti-tilt component 27 can adopt a roller-like structure or a shaft-like structure.

[0151] To improve the ease of installation of the anti-rollover component 27, a transition plate 220 is installed on one side of the sliding rod 222, and the anti-rollover component 27 is installed on the transition plate 220. This allows the spacing between the anti-rollover component 27 and the sliding rod 222 to be controlled by adjusting the dimensions of the transition plate 220. Furthermore, multiple sets of anti-rollover components 27 are arranged vertically at intervals, each set including at least two anti-rollover components 27 spaced apart vertically, with each set of anti-rollover components 27 corresponding to one transition plate 220, thus reducing the number of transition plates 220. Preferably, each set of anti-rollover components 27 is located between two adjacent stop assemblies 23 to improve the rationality of the spatial layout and reduce the probability of interference between the stop assembly 23 and the anti-rollover component 27.

[0152] like Figure 7 and Figure 11 As shown, in this embodiment, the sliding rod 222 is preferably a square steel structure, that is, the sliding rod 222 has a cavity. To improve the wiring convenience of the stop drive component 231, an inlet 2225 is provided on the upper rod section 2223 of the sliding rod 222. The inlet 2225 is preferably provided in a one-to-one correspondence with the stop drive component 231. The electrical wiring of the sliding drive component enters the interior of the sliding rod 222 through the inlet 2225; an outlet 2224 is provided on the lower rod section 2221 of the sliding rod 222. The electrical wiring exits the sliding rod 222 through the outlet 2224 and connects to the stop controller 210 or other structures to improve the wiring standardization and reduce the probability of the electrical wiring being pulled and damaged.

[0153] This invention also provides a display device production line, including a conveyor line 3, on which a screen support frame 5 for tilting and supporting a display device 4 is provided, and also includes the above-mentioned vertical support equipment, with a front blocking device 2 and a flipping device 1 located on opposite sides of the conveyor line 3. The display device production line provided by this invention can improve the production efficiency of the display device 4, reduce production costs, improve production safety and automation, and increase product yield.
