[0029] Display panels are often transported in turnover boxes during the production, cutting, and sales process, especially the Quarter Panel (a panel cut from a whole display panel), also known as Q-Panel, which is often transported in turnover boxes. Display panels are fragile items. In order to avoid damage during transportation, such as Figure 1 As shown, after the display panel is placed in the turnover box, the position of the display panel in the turnover box is often restricted and fixed by placing blocks around the display panel.

[0030] During the display panel production process, large panels are typically cut into smaller ones, which are then cut into multiple display panels of varying sizes based on product type. Consequently, the production process requires a variety of turnover boxes and blocks to accommodate these various display panel sizes, leading to high panel handling costs.

[0031] In one embodiment, Figure 2As shown, a turnover box is provided, which includes a box body 10 and a limiting assembly 20 arranged in the box body 10. The limiting assembly 20 includes a plurality of rails 21 and a plurality of limiting blocks 22. The rail 21 is arranged at the bottom of the box body 10 and the first end of the rail 21 is connected to the first edge of the box body 10. The limiting block 22 is slidably arranged on the rail 21. When the object to be turned over is placed on the bottom of the box body 10, the limiting block 22 is slid along the rail 21 until the limiting block 22 contacts the object to be turned over.

[0032] In the embodiment of the present application, the turnover box includes a box body 10. The box body 10 can be made of expanded polypropylene (EPP) plastic foam material.

[0033] The turnover box also includes a position limiting assembly 20 disposed within the box body 10. The position limiting assembly 20 includes a plurality of rails 21 and a plurality of position limiting blocks 22. The number of rails 21 and position limiting blocks 22 can be the same or different. If the number of rails 21 and position limiting blocks 22 is different, the number of position limiting blocks 22 can be twice the number of rails 21. For example, the position limiting assembly 20 can include two rails 21 and two position limiting blocks 22, or it can include two rails 21 and four position limiting blocks 22.

[0034] The track 21 is arranged at the bottom of the box 10. Figure 3 As shown, Figure 2 In the cross-sectional view of the middle turnover box at the AA line, the track 21 can be embedded in the bottom of the box body 10, and the side of the track 21 exposed from the box body 10 is lower than the bottom surface of the box body 10, so as to avoid the protrusion of the track 21 causing uneven force on the display panel placed on the bottom surface of the box body 10 and damage, thereby improving the reliability of the turnover box.

[0035] Therefore, during the preparation of the box body 10 , the rails 21 may be pre-buried at a preset position of the box body mold, and then the box body 10 may be formed through a foaming process.

[0036] The material of the track 21 can be aluminum to ensure the strength of the track 21 itself and further enhance the strength of the overall structure.

[0037] The first end of the track 21 is connected to the first edge of the turnover box. The first edge can be the long side of the turnover box or the short side of the turnover box.

[0038] Track 21 can be as above Figure 2 As shown, only the first end is connected to the box body 10, that is, the length of the track is less than the length of the adjacent edge of the first edge of the box body 10, thereby saving materials and reducing costs. Figure 5 As shown, the second end of the track 21 is connected to the second edge of the box body 10, and the first edge and the second edge are opposite to each other. Figure 2 As the main view of the turnover box, Figure 4This is the bottom view of the turnover box. Figure 5 for Figure 4 The cross-sectional view at the BB line of the middle turnover box shows that both ends of the track 21 are connected to the box body 10, and the track 21 runs through the box body 10, thereby ensuring that the strength distribution of the box body structure is uniform, and avoiding that when the box body 10 carries the object to be turned over, the box body structure is damaged due to the weight of the object to be turned over, thereby damaging the object to be turned over.

[0039] The limit block 22 is slidably set on the track 21, and the limit block 22 can slide along the length direction of the track 21. When the object to be turned over is placed at the bottom of the box 10, the limit block 22 slides along the track 21 to the edge of the object to be turned over and contacts the object to be turned over, thereby fixing the position of the object to be turned over in the turnover box, limiting the range of movement of the object to be turned over, and preventing the object to be turned over from shaking, collision, etc. during transportation and being damaged.

[0040] It should be noted that when the object to be turned over is placed at the bottom of the box 10, the actual movement of the limit block 22 is to a position 2-4 mm away from the edge of the object to be turned over, that is, there is a 2-4 mm gap between the edge of the object to be turned over and the limit block 22. On the basis of ensuring the position limiting function of the limit block 22 on the object to be turned over, it is avoided that the limit block 22 and the object to be turned over are in close contact, which may cause the object to be turned over to be subjected to unbalanced force or excessive force and damage. It can be understood that in the following description, the limit block 22 sliding to contact with the object to be turned over refers to the limit block 22 sliding to a position 2-4 mm away from the object to be turned over.

[0041] The limit block 22 can be made of a material with high strength and good toughness, such as acrylonitrile butadiene styrene (ABS). On the basis of limiting the object to be circulated, it ensures the flexibility of the contact position with the object to be circulated to avoid damaging the object to be circulated.

[0042] In one possible implementation, to accommodate the sizes of most display panels, the turnover box may have a length of 1452 mm, a width of 1233 mm, and a thickness of 110 mm.

[0043] The embodiment of the present application provides a turnover box, which includes a box body and a limiting assembly arranged in the box body, the limiting assembly including a plurality of tracks and a plurality of limiting blocks, the track being arranged at the bottom of the box body and the first end of the track being connected to the first edge of the box body, the limiting block being slidably arranged on the track, and when the object to be turned over is placed at the bottom of the box body, the limiting block is slid along the track until the limiting block contacts the object to be turned over. The embodiment of the present application sets a limiting assembly including a track and a limiting block in the turnover box, so that the limiting block can move along the track in the box body, thereby adapting to objects to be turned over of any size, and the position of the object to be turned over of any size can be limited by moving the position of the limiting block, thereby avoiding the need to configure limiting blocks of various sizes for the turnover box, and the flexible and variable limiting size also avoids the need to prepare boxes of various sizes, effectively reducing the cost of the turnover box, and at the same time, avoiding the redundancy of boxes and limiting blocks of certain sizes, further reducing the cost of the turnover box.

[0044] In one embodiment, the distance between the connection position between the first end of the rail 21 and the first edge of the box 10 and the end of the first edge is greater than the first preset distance and less than the second preset distance.

[0045] In the embodiment of the present application, the position of the connection between the first end of the track 21 and the first edge of the box body 10 within the first edge is restricted. The distance between the connection between the first end of the track 21 and the first edge of the box body 10 and the end of the first edge is greater than a first predetermined distance. This prevents the limit block 22 from deviating from the middle position of the object to be rotated when the object to be rotated is large. This ensures that when the limit block 22 contacts the object to be rotated, the contact position is located in the middle range of the edge of the object to be rotated, thereby ensuring the stability of the limit block 22 in limiting the position of the object to be rotated.

[0046] At the same time, the distance between the connection position between the first end of the track 21 and the first edge of the box body 10 and the end of the first edge is less than the second preset distance, so as to avoid the situation where, when the object to be turned over is small in size, the limit blocks 22 on the two tracks 21 connected to the adjacent edges of the box body 10 have not yet contacted the object to be turned over, the two limit blocks 22 have already contacted each other and blocked each other, and thus cannot continue to slide until they contact the object to be turned over, that is, the position of the object to be turned over cannot be restricted, thereby ensuring the effectiveness of the turnover box.

[0047] It can be understood that the limiting assembly 20 includes two rails 21 , which are respectively connected to adjacent edges of the box body 10 , and the ends of the first edges corresponding to the two rails refer to the diagonal ends of the box body 10 .

[0048] Preferably, the connection point between the first end of the track 21 and the first edge of the box 10 is located at a position 1 / 3 of the first edge. This 1 / 3 position can prevent the two limit blocks 22 on the two tracks 21 connected at adjacent edges of the box 10 from blocking each other and failing to restrict the position of the object when the object is small. It can also prevent the limit blocks 22 from deviating from the middle position of the object and failing to stably restrict the object when the object is large.

[0049] In the turnover box provided by the embodiment of the present application, the distance between the connection position of the first end of the track with the first edge of the box body and the end of the first edge is greater than the first preset distance and less than the second preset distance. The embodiment of the present application limits the distance between the connection position of the first end of the track with the first edge of the box body and the end of the first edge, so as to avoid the situation where the two limit blocks on the two tracks connected by the adjacent edges of the box body do not contact the object to be turned over when the object to be turned over is small, thus blocking each other and failing to restrict the position of the object to be turned over, thereby ensuring the effectiveness of the turnover box; at the same time, the limit blocks are prevented from deviating from the middle position of the object to be turned over when the object to be turned over is large, ensuring that when the limit blocks contact the object to be turned over, the contact position is located in the middle range of the edge of the object to be turned over, thereby ensuring the stability of the limit blocks in restricting the position of the object to be turned over.

[0050] In one embodiment, Figure 6 As shown, the track 21 includes a sliding groove 23 , and the limiting block 22 includes a body 24 and a sliding member 25 . One end of the sliding member 25 is connected to the body 24 , and the other end is movably connected to the sliding groove 23 .

[0051] In the embodiment of the present application, a sliding groove 23 is provided on the side of the track 21 exposed from the bottom surface of the box body 10. The limit block 22 includes a body 24 and a sliding member 25 fixedly connected to the body 24. The end of the sliding member 25 not connected to the body 24 is placed in the sliding groove 23 of the track 21 and is movably connected to the sliding groove 23, thereby allowing the limit block 22 to be movably connected to the track 21. When the sliding member 25 slides in the sliding groove 23, it drives the body 24 of the limit block 22 to slide on the track 21, thereby allowing the limit block 22 to flexibly move within the box body 10 and limit the position of objects of various sizes to be turned over.

[0052] The main body 24 may be an L-shaped structure, one side of which is movably connected to the track via a sliding member 25 , and the other side is used to contact the object to be circulated to limit the position of the object to be circulated.

[0053] In one possible implementation, Figure 7As shown, the sliding member 25 includes a positioning rod 251 and a fastener 252. The positioning rod 251 is connected to the fastener 252. One end of the positioning rod 251 matches the sliding groove 23 and slides along the sliding groove 23. The other end is connected to the body 24. The fastener 252 is used to fix the positioning rod 251.

[0054] That is, one end of the positioning rod 251 is fixedly connected to the body 24 of the limit block 22, and the other end is placed in the sliding groove 23 of the track 21, matching the sliding groove 23 and sliding along the sliding groove 23. The fastener 252 is connected to the positioning rod 251, thereby fixing the positioning rod 251.

[0055] When the limit block 22 slides on the track 21, the fastener 252 does not secure the positioning rod 251. When the limit block 22 slides and contacts the object to be transferred, the fastener 252 secures the positioning rod 251, allowing the limit block 22 to limit the position of the object to be transferred. Alternatively, when the turnover box is not in use, the fastener 252 secures the positioning rod 251, preventing the limit block 22 from sliding on the track 21 and preventing damage to the turnover box.

[0056] Among them, the positioning rod 251 can be a screw, which passes through the body 24 of the limit block 22 and is fixedly connected to the body 24. The fastener 252 can be a nut, which is connected to the other end of the positioning rod 251 and is placed in the sliding groove 23 of the track 21. The shape matches the sliding groove 23. Therefore, the positioning rod 251 can slide along the sliding groove 23.

[0057] When the limit block 22 slides on the track 21, the screw is loosened. When the limit block 22 slides to contact the object to be turned over, the screw is tightened in the nut, so that the limit block 22 can limit the position of the object to be turned over. Or when the turnover box is not in use, the screw is tightened in the nut to prevent the limit block 22 from sliding on the track 21 and preventing the turnover box from being damaged by collision.

[0058] In one embodiment, as above Figure 6 As shown, the body 24 includes a base 241, a buffer layer 242 and a support member 243. The base 241 is slidably connected to the track 21. The buffer layer 242 is arranged on the side of the base 241 away from the first edge of the box body 10, and the support member 243 is arranged on the side of the base 241 close to the first edge.

[0059] In the embodiment of the present application, the main body 24 of the limit block 22 includes a base 241, a buffer layer 242 covering the side of the base 241 that is in contact with the object to be circulated (i.e., the side away from the first edge of the box body 10), and a support member 243 arranged on the side of the base 241 that is not in contact with the object to be circulated (i.e., the side close to the first edge of the box body 10).

[0060] The base 241 is movably connected to the track via a slider 25. The base 241 can be an L-shaped structure, with one side of the L-shaped structure movably connected to the track via the slider 25, and the other side being used to contact and position the object to be rotated. The base 241 can be made of ABS.

[0061] The buffer layer 242 may be made of a thermoplastic elastomer (TPE) material, so that the limiting block 22 can flexibly contact the object to be circulated, thereby avoiding damage to the object to be circulated.

[0062] The support member 243 can enhance the structural strength of the base 241 , and can be made of the same material as the base 241 .

[0063] In the turnover box provided in the embodiment of the present application, the track includes a sliding groove, the limit block includes a body and a sliding member, one end of the sliding member is connected to the body, and the other end is movably connected to the sliding groove. In the embodiment of the present application, the limit block is movably connected to the track via the sliding member structure, so that the limit block can be flexibly moved within the box, and the position of objects to be turned over of various sizes is restricted, thereby avoiding the need to configure limit blocks of various sizes for the turnover box. The flexible and variable limit size also avoids the need to prepare boxes of various sizes, effectively reducing the cost of the turnover box. At the same time, it can avoid the redundancy of boxes and limit blocks of certain sizes, further reducing the cost of the turnover box.

[0064] In one embodiment, Figure 8 As shown, the turnover box further includes a stopper 30 , which is disposed on the inner side wall of the box body 10 and is located in the middle of the side wall. The stopper 30 protrudes from the inner side wall surface of the box body 10 .

[0065] In this embodiment, the stopper 30 is provided on the inner sidewall of the box 10 and is snap-connected to the box 10 for easy removal. The stopper 30 protrudes from the inner sidewall surface of the box 10 and is located at a non-end position of the sidewall, that is, in the middle of the sidewall, to prevent the corners of the object to be rotated from being damaged by force, thereby protecting the corners of the object to be rotated.

[0066] It is understandable that, among the edges of the box body 10 , the edges opposite to the edges where the objects to be circulated are not in contact with the limiting blocks 22 have stoppers 30 , and each edge of the box body 10 is provided with at least one stopper 30 .

[0067] In one possible implementation, when both ends of the track 21 are connected to the box 10, two limit blocks 22 can be configured on the track 21. When the object to be circulated is placed in the box 10, the two limit blocks 22 are distributed on both sides of the object to be circulated. The two limit blocks 22 simultaneously limit the position of the object to be circulated, and at the same time, they can also avoid the corners of the object to be circulated from being subjected to force, thereby achieving avoidance protection of the corners of the object to be circulated.

[0068] In one possible implementation, the bottom edge of the box 10 has a groove 70 that is recessed away from the object to be circulated, which is used to prevent desiccant from entering the box 10, keeping the inside of the box 10 dry, and preventing moisture inside the box 10 from leaving marks on the object to be circulated, while also preventing damage to the object to be circulated.

[0069] The turnover box provided in the embodiment of the present application also includes a stopper arranged on the inner side wall of the box body. The stopper is located in the middle of the side wall and protrudes from the inner side wall surface of the box body, which can prevent the corners of the object to be turned over from being damaged by force, that is, the avoidance protection of the corners of the object to be turned over can be achieved.

[0070] In one embodiment, Figure 9 As shown, the plurality of rails 21 include a first rail 26 and a second rail 27 . The first rail 26 is parallel to the length direction of the box body 10 , and the second rail 27 is parallel to the width direction of the box body 10 .

[0071] In the embodiment of the present application, the limiting assembly 20 may include two rails 21 , namely a first rail 26 and a second rail 27 . The two rails 21 are parallel to the length direction and the width direction of the box body 10 , respectively.

[0072] When both ends of the first track 26 and the second track 27 are connected to the edge of the box body 10, the first track 26 and the second track 27 are cross-distributed. One of the tracks 21 needs to be divided into two sub-tracks to meet the above cross-distribution.

[0073] For example, the first track 26 includes a first sub-track 261 and a second sub-track 262, one end of the first sub-track 261 is connected to the first edge of the box body 10, and the other end of the first sub-track 261 is connected to the second track 27, one end of the second sub-track 262 is connected to the second edge of the box body 10, and the other end of the second sub-track 262 is connected to the second track 27.

[0074] In a possible implementation, the length of the second track 27 may be 1097 mm, the length of the first sub-track 261 may be 864 mm, and the length of the second sub-track 262 may be 432 mm.

[0075] Based on the above-mentioned cross-distributed first track 26 and second track 27, as shown in FIG. Figure 10 As shown, the limiting assembly 20 further includes a track fixing member 28 , which is used to fix the first sub-track 261 and the second track 27 , and to fix the second sub-track 262 and the second track 27 .

[0076] The track fixing member 28 is arranged at the intersection of the first track 26 and the second track 27. The track fixing member 28 may include screws and L-shaped members. The L-shaped members are fixed to the two adjacent tracks by screws, thereby fixing the first sub-track 261 and the second track 27, and the second sub-track 262 and the second track 27.

[0077] In one possible implementation, Figure 11 As shown, the dimensions can be marked on the track 21 and the track can be used as a ruler, so that the staff can adjust the limit block 22 to achieve accurate limitation of the position of the turnover object.

[0078] In the turnover box provided in the embodiment of the present application, the multiple tracks include a first track and a second track. The first track is parallel to the length of the box, and the second track is parallel to the width of the box, and the first track and the second track are arranged in an intersecting manner. The tracks in the embodiment of the present application are parallel to the edge of the box, which facilitates the sliding adjustment of the limit blocks and improves the ease of operation of the turnover box. The intersecting track arrangement ensures a uniform strength distribution of the box structure, preventing the box structure from being damaged by the weight of the objects to be turned over when the box is loaded.

[0079] In one embodiment, Figure 12 As shown, the turnover box also includes a box cover 40. After the turnover object is placed, the box cover 40 is connected to the box body 10 to further limit the position of the turnover object within the box body 10, while preventing external objects from colliding with the turnover object and causing damage, further improving the stability and reliability of the turnover box.

[0080] In a possible implementation, a plurality of positioning holes 50 are provided on the bottom surface of the body 10 of the turnover box. The positioning holes 50 are distributed along the length and width of the body 10 , and the limit blocks 22 are detachably connected to the positioning holes 50 .

[0081] In an embodiment of the present application, multiple positioning holes can be opened at different positions on the bottom of the box body 10, and the limit block 22 is detachably connected to the positioning hole 50, so that after the object to be circulated is placed in the box body 10, the limit block 22 can be connected to the positioning hole at the edge of the object to be circulated according to the size of the object to be circulated, thereby realizing the position restriction of the object to be circulated.

[0082] In one embodiment, a turnover box is provided, which includes a box body 10 and a limiting assembly 20 arranged in the box body 10, the limiting assembly 20 includes a plurality of rails 21 and a plurality of limiting blocks 22, the rails 21 are arranged at the bottom of the box body 10 and the first end of the rails 21 is connected to the first edge of the box body 10, the limiting blocks 22 are slidably arranged on the rails 21, and when the object to be turned over is placed on the bottom of the box body 10, the limiting blocks 22 are slid along the rails 21 until the limiting blocks 22 contact the object to be turned over.

[0083] In the embodiment of the present application, a limiting assembly including a track and a limiting block is arranged in the turnover box, so that the limiting block can move along the track in the box, thereby adapting to objects to be turned over of any size. By moving the position of the limiting block, the position of the object to be turned over of any size can be restricted, thereby avoiding the need to configure limiting blocks of various sizes for the turnover box. The flexible and variable limiting size also avoids the need to prepare boxes of various sizes, effectively reducing the cost of the turnover box. At the same time, the redundancy of boxes and limiting blocks of certain sizes can be avoided, further reducing the cost of the turnover box.

[0084] The second end of the track 21 is connected to the second edge of the box 10, with the first edge and the second edge facing each other. That is, both ends of the track 21 are connected to the box 10, and the track 21 runs through the box 10, thereby ensuring uniform strength distribution within the box structure and preventing the box 10 from being damaged by the weight of the object being transported.

[0085] The distance between the connection point between the first end of the track 21 and the first edge of the box 10 and the end of the first edge is greater than the first preset distance and less than the second preset distance. Preferably, the connection point between the first end of the track 21 and the first edge of the box 10 is located at 1 / 3 of the first edge. The distance limitation can prevent the two limit blocks 22 on the two tracks 21 connected to the adjacent edges of the box 10 from blocking each other when the size of the object to be circulated is small, thereby making it impossible to limit the position of the object to be circulated; it can also prevent the limit blocks 22 from deviating from the middle position of the object to be circulated and failing to stably limit the object to be circulated when the size of the object to be circulated is large.

[0086] The track 21 includes a sliding groove 23, and the limit block 22 includes a body 24 and a sliding member 25. One end of the sliding member 25 is connected to the body 24, and the other end is movably connected to the sliding groove 23. The sliding member 25 includes a positioning rod 251 and a fastener 252. The positioning rod 251 is connected to the fastener 252. One end of the positioning rod 251 matches the sliding groove 23 and slides along the sliding groove 23, and the other end is connected to the body 24; the fastener 252 is used to fix the positioning rod 251. The body 24 includes a base 241, a buffer layer 242 and a support member 243. The base 241 is slidably connected to the track 21. The buffer layer 242 is arranged on the side of the base 241 away from the first edge of the box body 10, and the support member 243 is arranged on the side of the base 241 close to the first edge. The limit block is movably connected to the track through the sliding member structure, so that the limit block can move flexibly within the box body.

[0087] The turnover box also includes a stopper 30, which is provided on the side wall of the box body 10 and is located in the middle of the side wall. The stopper 30 protrudes from the surface of the inner side wall of the box body 10. This prevents the corners of the objects to be turned over from being damaged by force, that is, the corners of the objects to be turned over are avoided and protected.

[0088] The multiple rails 21 include a first rail 26 and a second rail 27. The first rail 26 is parallel to the length direction of the box body 10, and the second rail 27 is parallel to the width direction of the box body 10. The first rail 26 and the second rail 27 are cross-distributed. The first rail 26 includes a first sub-rail 261 and a second sub-rail 262. One end of the first sub-rail 261 is connected to the first edge of the box body 10, and the other end of the first sub-rail 261 is connected to the second rail 27. One end of the second sub-rail 262 is connected to the second edge of the box body 10, and the other end of the second sub-rail 262 is connected to the second rail 27. The limiting assembly 20 also includes a rail fixing member 28, which is used to fix the first sub-rail 261 and the second rail 27, and to fix the second sub-rail 262 and the second rail 27. The rails are parallel to the edge of the box body, which facilitates the sliding adjustment of the limit block, thereby improving the convenience of operation of the turnover box. Moreover, the cross distribution of the tracks can ensure that the strength of the box structure is evenly distributed, thereby preventing the box structure from being damaged due to the weight of the object to be turned over when the box carries the object to be turned over, thereby damaging the object to be turned over.

[0089] The turnover box also includes a box cover, which further limits the position of the turnover object in the box body 10 and prevents the turnover object from being damaged by collision or other damage from external objects, thereby further improving the stability and reliability of the turnover box.

[0090] In a possible implementation, a plurality of positioning holes are provided on the bottom surface of the turnover box, the positioning holes are distributed along the length direction and the width direction of the box, and the limiting blocks are detachably connected to the positioning holes.
