Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of glass sheet conveying equipment, and specifically to a glass sheet packaging and conveying box. Background Technology
[0002] In electronic devices such as computers, televisions, and ETC electronic displays, glass substrates are generally required as the inner screen of the display. Glass substrates are mostly produced using automated equipment. After inspection, they are sorted and transported by conveyor belts, with the thickness of the glass substrates decreasing as they are formed. After forming, they are generally transported to the next process or collected and stacked.
[0003] Glass substrates have relatively weak compressive strength. To ensure safe transport, some sizes of glass sheets need to be individually packaged, which increases costs. When transporting multiple glass sheets, due to their unique properties, they generally need to be transported vertically or at a certain angle to ensure safety.
[0004] In the prior art, there is a patent document with publication number CN219771160U and patent name: a glass forming and transporting device. In this document, a first conveying platform and a second conveying platform are set up, and the glass sheets are transported by using bearing seats and transmission rollers and other equipment. Since the transporting process of this device is still horizontal, when multiple glass sheets are stacked, even glass sheets of the same size will still have errors. When the errors accumulate to a certain extent, and then they are straightened, cracks will appear on the edges of the glass sheets, affecting the pass rate. Utility Model Content
[0005] To overcome the above-mentioned defects, the purpose of this utility model is to provide a glass sheet packaging and conveying box, which is equipped with a guide plate and a straightening device for quick straightening of glass sheets, facilitating subsequent packaging and reducing the risk of glass sheets being damaged by bumps.
[0006] To achieve the above objectives, this utility model provides a glass sheet packaging and conveying box, characterized in that it includes a box body and a cover plate fastened to the upper part of the box body; a guide plate is provided on the cover plate, one end of the guide plate being hinged to the cover plate via a rotating shaft; a height adjustment device is also provided between the guide plate and the cover plate, the height adjustment device being used to adjust and limit the height of the guide plate; a straightening device is also provided on the guide plate, the straightening device being used to straighten the position of the glass sheet.
[0007] Preferably, the height adjustment device includes a support plate and a limiting plate. The guide plate is provided with a slot, and the upper end of the support plate is fixed in the slot. The cover plate is provided with a through hole, and the lower end of the limiting plate slides in the through hole and is limited in its downward distance by the limiting plate.
[0008] Preferably, both the support plate and the limiting plate are provided with through limiting holes, and limiting pins are inserted into the limiting holes.
[0009] Preferably, the straightening device includes a bottom straightening plate and a side straightening plate. The two ends of the bottom straightening plate are movably engaged with the guide plate and are close to the bottom of the guide plate. There are two side straightening plates, which are detachably connected to the upper part of the guide plate respectively.
[0010] Preferably, the guide plate is further provided with a buffer device, which includes a buffer pad disposed at the bottom of the guide plate.
[0011] Preferably, the buffer device is further provided with a plurality of guide wheels, which are disposed at the ends of the guide plate, and the outer circumferential surface of the guide wheels is covered with a silicone layer.
[0012] Preferably, the box body has several storage slots at the bottom, and each storage slot is hinged with a set of folding wheels.
[0013] Preferably, the folding wheel assembly includes folding wheels and folding rods, and each folding rod is provided with a limiting block.
[0014] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:
[0015] 1. Because a guide plate is installed on the cover of the box, the tilt angle of the guide plate can be adjusted by a height adjustment device to better match the height of the conveyor belt. The glass sheets on the conveyor belt fall onto the guide plate in sequence. The glass sheets are then shaped by a sizing device. Finally, the shaped glass sheets are packaged together and placed into the box for overall conveying. In the above process, the glass sheets are stacked by their own weight, taking advantage of the characteristics of the conveyor belt. Therefore, there is no need to use additional handling tools such as robotic arms, resulting in lower costs. The position of the stacked glass sheets can also be quickly adjusted according to the number of stacked glass sheets, effectively avoiding the accumulation of errors and reducing the risk of collisions.
[0016] 2. Due to the inclusion of a straightening device for regularly straightening glass sheets, the bottom straightening plate is positioned at the bottom of the guide plate, while the side straightening plates are movably engaged at both ends of the guide plate, allowing for direct left and right side positioning. When a certain number of glass sheets are stacked, they can be grouped together by pushing and pulling the bottom straightening plate upwards. This multiple, small-scale straightening reduces the pressure and friction between the glass sheets, minimizing the risk of edge chipping. Furthermore, the dimensions will be more precise during final packaging, making transportation more convenient. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0027] See Figures 1-4 This utility model provides a glass sheet packaging and conveying box, including a box body 1 and a cover plate 11 fastened to the upper part of the box body 1; a guide plate 2 is provided on the cover plate 11, one end of the guide plate 2 is hinged to the cover plate 11 via a rotating shaft; a height adjustment device 3 is also provided between the guide plate 2 and the cover plate 11, the height adjustment device 3 is used to adjust and limit the height of the guide plate 2; a straightening device 4 is also provided on the guide plate 2, the straightening device 4 is used to straighten the position of the glass sheets. The height adjustment device 3 is mainly used to adjust the tilt angle of the guide plate 2 to match the height of the conveyor belt. Generally, the tilt angle should be kept at 30-45 degrees, and the tilt angle should not be too large, in order to control the downward speed. The glass sheets are relatively thin, and the stacking thickness should not be too high. Generally, after 6-8 glass sheets have fallen, the straightening device 4 can be used for straightening.
[0028] The height adjustment device 3 of this utility model includes a support plate 31 and a limiting plate 32. The guide plate 2 is provided with a slot, and the upper end of the support plate 31 is fixed in the slot. The cover plate 11 is provided with a through hole, and the lower end of the limiting plate 32 slides in the through hole and is limited in its downward distance by the limiting plate 32. Both the support plate 31 and the limiting plate 32 are detachable. Generally, the upper end of the support plate 31 is first snapped and fixed in the slot, and the lower end slides in the through hole. After adjusting the height, the limiting plate 32 is used to limit its downward distance. The limiting plate 32 can be directly tightened with screws, or it can be fixed by inserting a limiting pin into the through limiting hole 33. The limiting pin (not shown in the figure) can generally be replaced by a bolt. After connecting the limiting plate 32 to the support plate 31, it is sufficient to ensure that the support plate no longer moves downward. After adding the limiting plate 32, the thickness of the support plate 31 is significantly increased, and the contact area with the cover plate 11 is increased. Therefore, the stability is stronger and there will be no shaking during the entire material receiving process.
[0029] The straightening device 4 of this utility model includes a bottom straightening plate 41 and side straightening plates 42. The two ends of the bottom straightening plate 41 are movably engaged with the guide plate 2 and are located near the bottom of the guide plate 2. There are two side straightening plates 42, each detachably connected to the upper part of the guide plate 2. The bottom straightening plate 41 can slide up and down. When three or four glass sheets are placed on the guide plate 2, sliding the bottom straightening plate 41 straightens the glass sheets that have shifted a certain distance to the center, repeating the above steps. The two side straightening plates 42 serve to limit the glass sheets to the left and right, especially in the initial state, limiting and guiding the glass sheets. During packaging, the bottom straightening plate 41 and side straightening plates 42 can be used to fix the four corners of the glass sheets before placing them into the box 1, thus further improving transportation safety.
[0030] The guide plate 2 of this invention is further provided with a buffer device, which includes a buffer pad disposed at the bottom of the guide plate 2. The buffer device of this invention also includes several guide wheels 21, which are disposed at the ends of the guide plate 2, and the outer circumferential surface of the guide wheels 21 is covered with a silicone layer. The guide wheels 21 are used to guide the glass sheet and increase friction, resulting in a slower speed and preventing edge chipping. The buffer pad is also generally made of silicone, which is low in cost and easier to maintain.
[0031] The box body 1 of this utility model has several storage slots 12 at its bottom, and each storage slot 12 is hinged with a set of folding wheels 13. For long-distance transportation, the contact area between the folding wheels 13 and the ground is small, which is suitable for movement. At this time, the limiting block 141 on each folding rod 14 is used to limit its tilt position. Figure 3 (Left side). After moving to the designated position, the folding wheels 13 and folding rod 14 of the folding wheel set are stored in the storage slot 12. Figure 3(Right side) The entire bottom of box 1 is used for support, so even during long-distance transportation, the friction is large and there will be no large-scale shaking, making it more stable.
[0032] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
