Description
Technical Field
[0001] This utility model relates to the technical field of circular foam, and in particular to a circular foam transport device with high space utilization. Background Technology
[0002] The back of the display driver module (AM module) of the display needs to be covered with PET or black foam to protect the glass. In order to prevent the foam from getting dirty during the manufacturing process and transportation, which would affect the cleanliness of the foam, a blue release film is usually required on the surface of the foam. Before assembling the FPC of the AM module, the release film is removed by tearing the handle on the blue release film to complete the assembly.
[0003] In related technologies, the tear handle of the release film is designed to be directly above or below the foam (0-degree or 180-degree direction) or directly to the left or right (90-degree or 270-degree direction). The tear handle protrudes from the shape of the foam. When the foam is placed in the roll for transporting and layout, space must be reserved for the tear handle to ensure normal production and sampling. The position and size of the tear handle of the release film will increase the longitudinal width of the layout and will also affect the layout design and the space utilization of the roll, resulting in a smaller amount of foam placed in a roll and a lower space utilization of the roll. Utility Model Content

[0005] This utility model provides a high-space-utilization circular foam transport device, which adopts the following technical solution: a release film and a roll belt; the foam includes a circular main body and a protrusion, the protrusion being integrally connected to the circular main body; the release film covers the surface of the foam, the release film includes a tear handle, the central axis of the tear handle being at a 45-degree angle to the central axis of the protrusion; the roll belt has a strip-like structure, and multiple foams are attached to the surface of the roll belt in a line arrangement at equal intervals, the protrusions facing the long side line of the roll belt.
[0006] Optionally, the tear handle is rectangular, and the length of the long side of the tear handle is 3-5 cm.
[0007] Optionally, a slit is provided on the circular body of the foam, the slit is located opposite the protrusion, and the slit is parallel to the long side line of the roll.
[0008] Optionally, the width of the roll is greater than the diameter of the foam; the distance between the raised edge and the long edge of the roll is at least 3 centimeters.
[0009] Optionally, the spacing between two adjacent foams evenly arranged on the roll is at least 4 centimeters.
[0010] Optionally, it may also include: a spool disposed at the end of the wide side of the roll, the roll being wound around the spool.

[0012] Optionally, it also includes: attachment points, which are disposed on the surface of the roll tape, the surface being the side of the roll tape facing the winding drum, and arranged in a uniform row; the attachment points include multiple points, arranged in a line at equal intervals, and the foam 1 is located at the attachment points; wherein, when the roll tape 3 is unrolled, the attachment point closest to the winding drum 4 is defined as the first attachment point, and the first attachment point is the attachment point located at the very end of the roll tape among the multiple uniformly arranged attachment points.
[0013] Optionally, the inner diameter of the roll is 7-15 cm.
[0014] Any of the above-described technical solutions of this utility model has at least some of the following beneficial effects:
[0015] 1. By setting the tear handle on the release film at a 45-degree angle, the space occupied by the foam on the roll tape is reduced, allowing more foam to be attached to the roll tape, thereby improving the space utilization rate of the roll tape;
[0016] 2. The tear handle is a protruding structure designed for workers to tear off the release film.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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 this utility model.
[0027] This utility model discloses a circular foam transport device with high space utilization. (Refer to...) Figure 1 , Figure 2 and Figure 3 The system includes: a release film 2 and a roll tape 3; foam 1 includes a circular body 13 and a protrusion 11, the protrusion 11 being integrally connected to the circular body 13; the release film 2 covers the surface of the foam 1, the release film 2 includes a tear handle 21, the central axis of the tear handle 21 is at a 45-degree angle to the central axis of the protrusion 11; the roll tape 3 has a strip-like structure, multiple foams 1 are attached to the surface of the roll tape 3 in a line with equal spacing, and the protrusion 11 is oriented towards the long side line of the roll tape 3.
[0028] Based on the above structure, foam 1, used to protect the display driver module of the screen, needs to have the same shape as the display driver module to provide comprehensive protection. The display driver module is roughly circular. To ensure that the display driver module does not wobble after being attached to the screen, a convex structure is provided on the display driver module. This convex structure can be engaged in a pre-made groove, thus preventing the display driver module from wobbling. Because the display driver module has a convex structure, foam 1 also needs to have corresponding protrusions 11 to comprehensively protect every part of the display driver module, effectively preventing the display from malfunctioning due to impacts to the display driver module.
[0029] Optionally, the circular body 13 of foam 1 is designed to fit a circular display screen, and the protrusions 11 of foam 1 are snapped into pre-made grooves to prevent shaking and effectively protect the display driver module. Foam 1 is attached to the display driver module by adhesive, so both surfaces of foam 1 are provided with adhesive. To prevent the adhesive from being contaminated and causing foam 1 to fail to adhere to the display driver module, a release film 2 needs to be attached to the surface of foam 1. During the process of attaching foam 1 to the display driver module, the release film 2 needs to be peeled off. To make it easier to peel the release film 2 off foam 1, a tear handle 21 is provided on the release film 2. The release film 2 is lifted by the tear handle 21, thereby achieving the effect of easier peeling off of the release film 2.
[0030] Optionally, after manufacturing, foam 1 will be transported to the installation factory. During transportation, a roll of conveyor belt 3 will be used to arrange foam 1, making it more orderly and easier to transport. The side of foam 1 without release film 2 will be attached to the roll of conveyor belt 3. Multiple foams 1 will be evenly arranged on the roll of conveyor belt 3, making the scattered foams 1 orderly and convenient for transportation.
[0031] Optional, refer to Figure 1 To improve the space utilization of foam 1 on the roll 3, the tear handle 21 is positioned so that the center of foam 1 faces diagonally upwards, i.e., the central axis of the tear handle 21 forms a 45-degree angle with the central axis of the protrusion 11. When foam 1 with release film 2 attached is placed on the roll 3, the volume of the tear handle 21 does not exceed the outermost volume space of foam 1. Figure 3 It can be seen that the rightmost position of the tear handle 21 does not exceed the rightmost end of the diameter of the foam 1. After multiple foams 1 are arranged, there is no need to reserve space for the tear handle 21. The width required to arrange one foam 1 is only the diameter of the foam 1, which effectively reduces the volume occupied by the foam 1 and improves the space utilization of the roll tape 3.
[0032] Optionally, the position of the tear handle 21 on the release film 2 is set at a 45-degree angle, which reduces the space occupied by the foam 1 on the roll 3, allowing more foam 1 to be attached to the roll 3, thereby improving the space utilization rate of the roll 3.
[0033] In this preferred embodiment, the tear handle 21 is rectangular, and the length of the long side of the tear handle 21 is 3-5 cm.
[0034] Based on the above structure, foam 1 is suitable for use in circular display devices, such as watches. The diameter of the watch face is about 10 cm. If the long side of the tear handle 21 is too long, the rightmost end of the tear handle 21 may extend beyond the rightmost edge of foam 1, which would increase the space occupied by foam 1. Therefore, the length of the tear handle 21 should not exceed 5 cm. When the length of the tear handle 21 is less than 5 cm, according to the Pythagorean theorem, the maximum length of the tear handle 21 mapped onto foam 1 in the 90-degree direction is 4 cm. This effectively ensures that the rightmost side of the tear handle 21 does not exceed the rightmost edge of foam 1, thus effectively improving the space utilization rate on the roll 3.
[0035] Optional, refer to Figure 2 The tear handle 21 is a protruding structure designed for workers to tear off the release film 2. If the length of the tear handle 21 is too short, workers will not be able to easily grasp the tear handle 21 and may not be able to easily tear off the release film 2. Therefore, the length of the tear handle 21 needs to be greater than 3 cm so that workers can grasp the tear handle 21.
[0036] In this preferred embodiment, a slit 12 is provided on the circular body of the foam 1. The slit 12 is located opposite to the protrusion 11 and is parallel to the long side line of the roll 3.
[0037] Based on the above structure, the convex structure of the display driver module is engaged in the groove. When the display driver module is installed on the display screen, it may rotate circumferentially during shaking. The convex structure restricts its rotation. However, to avoid uneven force on the convex structure due to the restriction by the convex structure alone, a chamfer is set on the opposite side of the convex structure of the display driver module to form a straight chamfer 12. The groove where the display driver module is placed is also set with a corresponding chamfer 12, so that the display driver module has engagement positions at both the top and bottom, thus avoiding uneven force on the display driver module when it rotates.
[0038] Optional, refer to Figure 1 Since foam 1 and display driver module have the same area, foam 1 is also provided with a chamfer 12, so as to achieve all-round protection of display driver module by foam 1.
[0039] In this preferred embodiment, the width of the roll 3 is greater than the diameter of the foam 1; the distance between the edge of the protrusion 11 and the long edge of the roll 3 is at least 3 centimeters.
[0040] Based on the above structure, foam 1 is attached to roll 3. In order to protect foam 1 in all directions, the width of roll 3 needs to be set to be greater than the diameter of foam 1, so as to avoid the upper and lower ends of foam 1 being bumped.
[0041] Optional, refer to Figure 3 The distance between the upper edge of the roll 3 and the edge of the protrusion 11 is set to 4 cm, and the distance between the cut edge 12 and the lower edge of the roll 3 is set to 4 cm, which effectively prevents the upper and lower ends of the foam 1 from being bumped.
[0042] In this preferred embodiment, the spacing between two adjacent foams 1 evenly arranged on the roll 3 is at least 4 cm.
[0043] Based on the above structure, referring to Figure 3 In order to neatly arrange the foam 1 and avoid the adjacent foam 1 from colliding when the roll tape 3 is squeezed due to too close spacing, the distance between two adjacent foam 1 is set to more than 4 cm, which effectively improves the neatness and avoids the overlap of two adjacent foam 1 after collision.
[0044] In a preferred embodiment, it further includes: a drum 4, which is disposed at the end of the wide side of the roll 3, and the roll 3 is wound around the drum 4.
[0045] Based on the above structure, referring to Figure 3 To facilitate sorting and storage, the long strip of packaging tape 3 is wound around the roll 4, thereby transforming the space occupied during transportation from a long planar space to a three-dimensional space, effectively reducing the space occupancy rate.
[0046] In this preferred embodiment, the side of the roll tape 3 that is attached to the foam 1 is wound towards the roll 4.
[0047] Based on the above structure, referring to Figure 3 The foam 1 side of the roll 3 is wound towards the roll 4, so that the foam 1 is always protected inside. At the same time, the upper and lower ends of the roll 3 exceed the diameter of the foam 1. After the roll 3 is wound, the upper end of the roll 3 cannot touch the foam 1. When the upper end of the roll 3 is bumped, it will protect the internal foam 1 from damage.
[0048] In a preferred embodiment, the method further includes: attachment points, which are disposed on the surface of the roll 3 and located on the side of the roll 3 facing the winding drum 4, arranged in a uniform row; the attachment points include multiple points, arranged in a line at equal intervals, with foam 1 located at the attachment points; wherein, when the roll 3 is unrolled, the attachment point closest to the winding drum 4 is defined as the first attachment point, which is the attachment point located at the very end of the roll 3 among the multiple uniformly arranged attachment points.
[0049] Based on the above structure, referring to Figure 3 When the roll 3 is wound on the drum 4, in order to ensure that the foam 1 is in contact with the roll 3, a certain distance is reserved between the roll 3 and the connection end of the drum 4, so that the roll 3 is wound around the drum 4 once, and then the roll 3 with the foam 1 is wound on, so that the foam 1 is always in contact with the roll 3.
[0050] Optionally, not only is a certain distance reserved on the left side of the first foam 1, but also on the right side of the last foam 1, so that after the last foam 1 is wrapped, the roll tape 3 will wrap around again, effectively protecting all foam 1 inside and preventing foam 1 from being exposed to the external environment and being hit or dirty.
[0051] In this preferred embodiment, the inner diameter of the roll 4 is 7-15 cm.
[0052] Based on the above structure, referring to Figure 3 When the inner diameter of the roll 4 is small, the foam 1 wound onto the roll 4 first will bend as the outer edge of the roll 4 bends more, which will cause the foam 1 to bend and deform. It may not be able to deform back to its original state during subsequent use. Therefore, the inner diameter of the roll 4 needs to be set to be greater than 7 cm.
[0053] Optionally, if the inner diameter of the roll 4 is too large, it will result in a larger space occupation. During transportation, the number of rolls 4 placed in the same carriage will be reduced. Therefore, the outer diameter of the roll 4 should be set to less than 15 cm to effectively improve space utilization.
[0054] The implementation principle of the circular foam transport device with high space utilization in this embodiment of the utility model is as follows:
[0055] Draw a vertical straight line passing through the center of foam 1. Rotate the vertical line 45° around the center of foam 1 to obtain the rotated straight line. Use this straight line as the symmetrical center line of the tear handle 21 of release film 2. Set the tear handle 21 (5*5) at the symmetrical center line position of the tear handle 21 of release film 2. The size of the tear handle 21 obtained in this way is still within the circular shape range of foam 1. After using foam 1 and release film 2 to lay out on roll tape 3, there is no need to add space for tear handle 21. This can greatly improve the layout space utilization of foam 1, effectively achieving the effect of improving layout utilization and saving production costs.
[0056] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
