Abstract
Description
Technical Field
[0001] This invention relates to the field of glass storage technology, specifically to an anti-tipping turnover rack for ultra-thin float electronic glass. Background Technology
[0002] With the development of the optoelectronic materials industry, the trend of lightweight glass is becoming more and more obvious. The thickness requirements for ultra-thin float electronic glass are getting higher and higher, and the glass produced is getting thinner and thinner, such as 0.25mm, 0.2mm, 0.15mm, etc.
[0003] Currently, when ultra-thin float electronic glass with a thickness of less than 0.3mm is stacked on the cold-end production line using robotic arms, the large size and thinness of the glass substrate make it prone to tipping and slipping during stacking. This risk increases further with the number of sheets stacked. Current methods to prevent tipping or slipping include increasing the tilt angle of the workstation's turnover rack and manually applying glass spacers or foam boards. However, these methods are not very effective, negatively impact production efficiency, and pose potential safety hazards.
[0004] In addition, finished glass needs to be placed in transport vehicles and transported to the next production site. This process requires the use of turnover racks. Currently, most turnover racks at workstations use ropes to secure the glass, which makes the glass prone to tipping over or breaking during placement and transportation. When packaging finished products, the ropes need to be untied for packaging and sealing, which further increases the risk of tipping over, causes production waste, and increases safety hazards in the workshop working environment.
[0005] A search revealed that existing technology, such as the one disclosed in CN107933658A, provides a glass transport rack, which includes a base, a support frame, and a glass positioning device. The glass positioning device comprises an upper positioning device symmetrically positioned relative to the center of the base and a positioning block on the surface of the base, all located above a top support. The upper positioning device includes a bearing seat above the top support, a rotating shaft mounted on the bearing seat, and a ratchet mounted on the end of the rotating shaft. A rotating rod is fixedly mounted on the rotating shaft, and a pressure plate is connected to the end of the rotating rod. The pressure plate and the rotating rod are hinged together. A pawl mounting bracket is located above the top support, and a pawl is connected to the bracket via a spring. The end of the pawl contacts the ratchet. This structure utilizes the rotating pressure plate acting on the glass on the support frame to create contact and limit the glass, improving the stability and firmness of the glass positioning.
[0006] For example, a glass transport anti-tipping turnover device with publication number CN114803107A includes a loading base with inclined surfaces on both sides. A support platform is set at the bottom of the inclined surfaces, and limit devices are set at both ends of the support platform. A connecting plate is rotatably connected to one edge of the support platform. A hydraulic rod is hinged to the bottom of the support platform near the connecting plate via a frame, and the top of the hydraulic rod is hinged to one side of the surface of the connecting plate. A pressing device is set on the top of the surface of the connecting plate. A buffer pad is fixedly connected to the surface of the loading base at the inclined surface, and a support device is set on the surface of the loading base near the buffer pad. An air passage is opened inside the loading base near the end, and the two ends of the air passage are connected to the limit device and the support device, respectively. This solution, by connecting the two ends of the air passage to the limit device and the support device, promotes the limiting of the glass. By utilizing the interrelationship between the structures, the entire device can press the glass tightly, reducing the impact of external forces or vibrations, making it less prone to random movement or tipping, ensuring safety and reliability, and improving transportation efficiency and performance.
[0007] However, neither of the above two solutions is suitable for storing ultra-thin float electronic glass. Both are storage structures that place the glass at an angle, which means that the back of the glass cannot be effectively supported. Since ultra-thin float electronic glass is large in size and thin in thickness, this storage structure causes the lower part of the ultra-thin float electronic glass to be concave. When multiple glass plates are placed together, the self-weight of the concave area is greater than the load-bearing capacity of the glass plate itself, making it more likely to crack or even break, resulting in losses.
[0008] More importantly, in the cold end production line of ultra-thin float electronic glass, under the corresponding production cycle, the stacking robot needs to grab glass sheets multiple times and place them one by one on the workstation turnover rack, and the time interval between grabbing and placing the sheets is short. The above two solutions are for storing a fixed number of glass sheets, which can only keep the glass stable in a static state, and neither can achieve stable fixation of the glass in the process of dynamically stacking the glass one by one. Summary of the Invention
[0009] To address the issues of unstable dynamic storage during the storage, transportation, and cold-end production line of ultra-thin float electronic glass in existing technologies, this invention provides an anti-tipping turnover rack for ultra-thin float electronic glass. This improves the stability of online stacking and storage of ultra-thin float electronic glass, avoids breakage during online storage, and enhances production efficiency and product qualification rate.
[0010] It adopts the following technical solution:
[0011] An anti-tipping turnover rack for ultra-thin float electronic glass includes a frame body, the frame body includes a base and a support frame connected to the base, the upper surface of the base forms a right angle with the inner support surface of the support frame, and the upper surface of the base has an angle with its lower surface, the upper surface of the base supports an upright glass plate, and the inner support surface of the support frame supports the surface of the glass plate, so that the glass plate is tilted backward for support.
[0012] The support frame is equipped with an upper stop mechanism, which includes a rotating shaft. The rotating shaft is connected to an arc-shaped swing arm and a drive motor. An upper baffle is provided on the front end of the arc-shaped swing arm. The drive motor can drive the rotating shaft to rotate and simultaneously drive the arc-shaped swing arm to swing, so that the upper baffle presses against the upper side of the outer surface of the glass plate.
[0013] The base is provided with a lower stop mechanism, which includes a first telescopic arm. The telescopic direction of the first telescopic arm is perpendicular to the surface direction of the glass plate. The moving end of the first telescopic arm is provided with a lower stop plate. The surface of the lower stop plate is parallel to the surface of the glass plate. When the moving end of the first telescopic arm moves, the lower stop plate presses against the lower side of the outer surface of the glass plate.
[0014] The frame is also equipped with a sensor to detect the number of glass plates stored. The sensor is electrically connected to the control module, which controls the extension length of the first telescopic arm and the rotation angle of the drive motor to adjust the clamping and fixing of different numbers of stacked glass plates.
[0015] Furthermore, the upper blocking mechanism also includes a second telescopic arm, the extension and retraction direction of which is parallel to the surface direction of the glass plate, and the rotation shaft is located on the extension and retraction end of the second telescopic arm.
[0016] Furthermore, the upper baffle is provided with a first adjustable belt of adjustable length, and the lower baffle is provided with a second adjustable belt of adjustable length. The free ends of the first and second adjustable belts are detachably connected. The upper and lower baffles, the first and second adjustable belts, and the frame can form a closed space to restrict the swaying of the glass plate.
[0017] Furthermore, the sensor is a photoelectric ranging sensor, and the photoelectric ranging target of the sensor is the spacer paper adsorbed on the glass plate.
[0018] Furthermore, the lower baffle is hinged to the moving end of the first telescopic arm, allowing the lower baffle to swing in the vertical plane. The lower baffle and the moving end of the first telescopic arm are also connected to both ends of the telescopic cylinder, and the telescopic cylinder's telescopic movement drives the lower baffle to open and close. The folded lower baffle is lower than the upper surface of the base.
[0019] Furthermore, the base is also provided with a groove for accommodating the folded lower baffle.
[0020] Furthermore, the first and second telescopic arms are linear reciprocating mechanisms with stroke control.
[0021] Furthermore, the frame is provided with limiting holes for positioning production line stations.
[0022] Furthermore, the frame is also provided with forklift holes for use with forklift inserts.
[0023] Furthermore, the upper surface of the base is also provided with an anti-slip pad.
[0024] The advantages of this invention compared to the prior art are as follows:
[0025] The present invention uses a structure in which the upper surface of the base forms a right angle with the inner support surface of the bracket, and the upper surface of the base has an angle with the lower surface of the base. This structure allows the glass plates to be stacked together and supported backward. It can prevent the glass plates, especially those stacked vertically, from slipping while providing a more stable support surface, thereby improving storage stability.
[0026] By setting up upper and lower baffle mechanisms, and using the upper and lower baffles to press against the upper and lower sides of the glass plate respectively, the stability of the glass plate stacking is further improved, avoiding the breakage of ultra-thin float electronic glass during online storage, and improving production efficiency and pass rate.
[0027] By setting up detachable first and second adjustment belts, they, along with the upper and lower baffles and the frame, can form a closed space, which can effectively limit the shaking of stacked glass panels, improve stability during storage and transportation, and effectively protect the glass panels.

Detailed Implementation
[0037] To make the present invention clearer, the following description, in conjunction with the accompanying drawings, further illustrates an anti-tipping workstation turnover rack for ultra-thin float electronic glass. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Example 1
[0038] like Figure 1 , Figure 2 As shown, an anti-tipping turnover rack for ultra-thin float electronic glass includes a frame 100, which is mainly constructed by welding profiles and steel plates. It includes a base 110 and a support frame 120 welded to the base 110. The base 110 comprises a frame-shaped frame with a pair of parallel tubing on both sides. Each pair of tubing is connected to a wider-section tubing at its lower side as a load-bearing structure. The support frame 120 is also a frame-shaped frame constructed by welding tubing and steel plates, with a pair of parallel tubing on both sides. The upper surface of the base 110 forms a right angle with the inner support surface of the support frame 120. The area formed by this right angle serves as the storage location for the ultra-thin float electronic glass; that is, the upper surface of the base 110 supports the bottom edge of the upright glass plate, and the inner support surface of the support frame 120 supports the surface of the glass plate. Furthermore, the upper and lower surfaces of the base 110 form an angle α, for example, α is 5°. The distance between the upper and lower surfaces of the base 110 gradually decreases in the direction from the free end of the base 110 to the connecting end of the support frame 120. This means that when the frame 100 is placed on a horizontal surface, the glass panels within the frame 100 are supported in a backward-tilting manner. This provides a more stable support surface and prevents the glass panels, especially those stacked vertically, from slipping, thereby improving storage stability. In addition, the upper surface of the base 110 is also provided with an anti-slip pad 111 to further prevent slippage on the lower surface of the glass panels and to prevent breakage due to excessive rigid compression.
[0039] The support frame 120 is equipped with upper blocking mechanisms 200. Specifically, there are two upper blocking mechanisms 200, located on both sides of the support frame 120. Each upper blocking mechanism 200 includes a rotating shaft 201, which can rotate at its connecting point. In this embodiment, the rotating shaft 201 can be located in a hinge hole (not shown) in the support plate of the support frame 120. A drive motor 202 is connected to one end of the rotating shaft 201 and is fixed to the support plate. An arc-shaped swing arm 203 is fixedly connected to the other end of the rotating shaft 201. The arc-shaped swing arm 203 can rotate together with the rotating shaft 201. An upper baffle 204 is also fixedly connected to the free end (front end) of the arc-shaped swing arm 203. The upper baffle 204 is preferably made of rubber and has an arc-shaped surface that can better elastically contact and press against the upper surface of the glass plate. The curved shape of the arc-shaped swing arm 203 can avoid the upper edge of the glass plate during its movement, increasing the height range of the glass that the frame can store.
[0040] Combination Figure 3 As shown, the base 110 is provided with a lower stop mechanism 300. Specifically, there are two lower stop mechanisms 300, respectively located on both sides of the base 110. Each lower stop mechanism includes a first telescopic arm 301, which is located inside the tube and its tail is fixed by a connecting plate. The telescopic direction of the first telescopic arm 301 is perpendicular to the surface of the glass plate. A lower stop plate 302 is provided on the moving end of the first telescopic arm 301. The lower stop plate 302 extends out of the tube and its surface is parallel to the surface of the glass plate. Correspondingly, the tube is provided with a sliding groove 112 to avoid interfering with the movement of the lower stop plate 302. When the moving end of the first telescopic arm 301 moves, the lower stop plate 302 can press against the lower side of the outer surface of the glass plate. Here, the first telescopic arm 301 is a linear reciprocating mechanism with stroke control, such as an electric cylinder.
[0041] Furthermore, the lower baffle 302 has a folding function, combined with Figure 4As shown, the lower baffle 302 is hinged to the moving end of the first telescopic arm 301, allowing the lower baffle 302 to swing in the vertical plane. The lower baffle 302 and the moving end of the first telescopic arm 301 are also connected to the two ends of the telescopic cylinder 303, which has a fixed stroke. When the telescopic cylinder 303 extends, it can drive the lower baffle 302 to open, that is, the lower baffle 302 is parallel to the glass plate surface. When the telescopic cylinder 303 retracts, the lower baffle 302 folds back into the slide groove 112 and is lower than the upper surface of the base 110. Here, the chute 112 has sufficient length to ensure that the lower baffle 302 does not interfere with the first telescopic arm 301 during its travel. The moving end of the first telescopic arm 301 is a body 304. The lower side of the body 304 has a pivot structure that can be hinged to the telescopic cylinder 303, and the end side has a pivot structure that can be hinged to the lower baffle 302. It also has a slot to allow the telescopic cylinder 303 to extend and retract. The slot can partially accommodate the telescopic cylinder 303. As an adaptation design in the art, the body 304 is only for illustrative purposes. In this way, the lower baffle 302 with folding function can facilitate the storage and stacking of multiple turnover racks, reducing the floor space occupied.
[0042] A sensor bracket 101 is also connected to the frame of the base 110. A sensor 401 is fixedly connected to the sensor bracket 101, with the detection end of the sensor 401 facing the glass surface, thereby detecting the quantity of glass stored. (Combined with...) Figure 5 As shown, the sensor 401 is electrically connected to the control module 402. The control module 402 controls the extension length of the first telescopic arm 301 and the rotation angle of the drive motor 202 to adjust the moving position of the lower baffle 302 and the swing position of the upper baffle 204, thus clamping and fixing different numbers of stacked glass plates. In this embodiment, the sensor 401 is a photoelectric ranging sensor. Based on the total stacked thickness of the electronic float glass of known thickness, the sensor 401 measures the thickness between the outermost glass and the sensor to calculate the number of glass plates stored. The control module 402 adjusts the positions of the upper and lower baffles accordingly based on the parameter information. To improve the measurement stability of the photoelectric ranging sensor, combined with... Figure 6 As shown, each glass plate is also respectively adsorbed with opaque spacer paper 102. The spacer paper 102 itself is a common protective measure in the industry and can play a protective role during the processing and transportation of glass plates. In this embodiment, it can more stably reflect the ranging light, providing a stable target for the photoelectric ranging of sensor 401.
[0043] When this device is used on a cold-end production line, the robotic arm places a single glass plate with spacer paper 102 attached onto the frame 100. At this time, both the upper and lower baffles are open, providing sufficient storage path and space for the moving glass plate. Then, based on the detection signal from sensor 401, control module 402 controls the operation of the first telescopic arm 301 and the drive motor 202, pressing the upper and lower baffles against the upper and lower sides of the placed glass plate. When the next glass plate is placed in front of the frame 100, control module 402 controls the upper and lower baffles to open. This cycle continues until the set number of glass plates are stacked. Control module 402 can have remote or local operation capabilities.
[0044] In addition, in order to accurately position this device at the designated work station, combined with Figure 6 As shown, the frame 100 is provided with limiting holes 103. In this embodiment, there is a pair of limiting holes 103, which extend vertically through the rear end of the base 110. In addition, in order to facilitate the rapid movement and transfer of the turnover rack at different workstations, the frame 100 is also provided with forklift holes 104 for forklift pallet insertion. In this embodiment, the inner holes of a pair of tubes on the lowest side of the base 110 are used as forklift holes 104.
[0045] Since this device can be used not only at the workstations of the cold-end production line, but also in storage and transportation, the turnover rack also has the following structure, combined with... Figure 1 As shown, the upper baffle 204 is equipped with an adjustable first adjustment strap 501. One end of the first adjustment strap 501 is fixed to the upper baffle by means of sewing, perforation, or other methods, while the other end is a free end. The adjustment function of the first adjustment strap 501 is conventionally achieved through adjusting buckles, which will not be elaborated here. The lower baffle 302 is equipped with an adjustable second adjustment strap 502. The structure of the second adjustment strap 502 is the same as that of the first adjustment strap 501. The free ends of the first and second adjustment straps are detachably connected, for example, by means of snap fasteners or knotted ropes. Thus, when the turnover rack stores a sufficient number of glass plates, the first and second adjustment straps are connected, allowing the upper and lower baffles, the first and second adjustment straps, and the rack 100 to form a closed space. This structure effectively limits the swaying of stacked glass plates, improves stability during storage and transportation, and effectively protects the glass plates. Example 2
[0046] This embodiment further adds a structure based on Embodiment 1: combining Figure 8As shown, the upper blocking mechanism 200 also includes a second telescopic arm 205. The telescopic direction of the second telescopic arm 205 is parallel to the surface direction of the glass plate. The rotating shaft 201 is hinged to the telescopic end of the second telescopic arm 205 and can move with the telescopic movement. Here, the second telescopic arm 205 is also a linear reciprocating mechanism with stroke control, such as an electric cylinder. The control module 402 is electrically connected to the second telescopic arm 205 and controls the telescopic distance of the second telescopic arm 205. With the above structure, it can adapt to a wider range of glass plate heights, improving the adaptability of this device for storing glass plates of different sizes.
[0047] The above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
