Description

Technical Field

[0001] This utility model relates to the field of float glass production equipment, and in particular to a glass stacking positioning device and a glass stacking production line. Background Technology

[0002] In the cold-end process of a float glass production line, after the glass is cut, it needs to be picked up and stacked by a robotic arm. To improve stacking accuracy, positioning blocks are used to position the glass before the robotic arm picks it up.

[0003] Currently, nylon positioning blocks are commonly used. However, these blocks have the following drawbacks: During operation, each time the robotic arm picks up a piece of glass, the glass impacts the nylon positioning block at the same location. After repeated and frequent impacts, a dent appears at the same spot on the surface of the nylon positioning block. Typically, after about three months, when the dent reaches a certain depth, subsequent glass pieces will get stuck in the dent during positioning. When the robotic arm picks up and lifts the glass, the obstruction caused by the dent leads to edge breakage, resulting in glass damage, affecting product quality and production efficiency. Therefore, the nylon positioning block must be replaced. Utility Model Content

[0004] This invention provides a glass stacking positioning device and a glass stacking production line, which can solve the defect in the prior art where glass is damaged due to the grooves caused by impact of nylon positioning blocks.

[0005] To solve the above-mentioned technical problems, this utility model provides a glass stacking and positioning device, including: a lifting mechanism and a positioning mechanism; The lifting mechanism is vertically and vertically positioned below the glass conveyor belt, used to lift the glass away from the glass conveyor belt; The positioning mechanism is located on the side of the glass conveyor belt and includes a freely rotatable positioning component. The positioning component is located above the glass conveyor belt. The side of the glass, after being lifted, contacts and is positioned by the positioning component. When the glass is lifted and separated from the positioning component, it can be driven by friction to rotate, thereby changing the contact positioning area on its peripheral wall.

[0006] In a preferred embodiment of this utility model, the positioning mechanism includes a mounting support, a rotating shaft, and a free positioning wheel; The rotating shaft is rotatably supported on the mounting bracket by bearings; The free positioning wheel is fitted onto the rotating shaft.

[0007] In a preferred embodiment of this utility model, the free positioning wheel is fitted onto the rotating shaft with a clearance fit and is able to rotate relative to the rotating shaft.

[0008] In a preferred embodiment of this utility model, positioning rings are provided on both sides of the free positioning wheel.

[0009] In a preferred embodiment of this utility model, the outer circumferential surface of the free positioning wheel is a smooth cylindrical surface.

[0010] In a preferred embodiment of this utility model, the outer peripheral surface of the free positioning wheel is a friction layer.

[0011] In a preferred embodiment of this invention, the friction layer is a rubber layer.

[0012] To solve the above-mentioned technical problems, this utility model also provides a glass stacking production line, including a glass conveyor belt, a robotic arm for gripping glass, and at least one set of the above-mentioned glass stacking positioning devices.

[0013] The beneficial effects of this utility model are as follows: This utility model is a glass stacking and positioning device. Through the design of the lifting mechanism and the positioning mechanism, the fixed impact is changed to rotational contact, which fundamentally eliminates the possibility of forming local dents. This avoids the problem of edge and corner breakage caused by jamming when the glass is lifted, and greatly slows down the wear rate. The positioning mechanism of this utility model has a simple structure, is easy to install and maintain, and is highly practical. Attached Figure Description

Detailed Implementation

[0015] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0016] Example 1 like Figure 1 As shown, this utility model discloses a glass stacking and positioning device, including: a lifting mechanism 10 and a positioning mechanism 20.

[0017] The lifting mechanism 10 is a positioning lifting frame driven by a cylinder or motor, which is vertically and flexibly installed below the glass conveyor belt 30 to lift the glass 40 away from the glass conveyor belt 30.

[0018] The positioning mechanism 20 is located on the side of the glass conveyor belt 30, and specifically includes: a mounting support 21, a rotating shaft 22, a free positioning wheel 23, and a positioning ring 25.

[0019] Specifically, there are two mounting supports 21, typically welded or cast from steel, which are bolted to the frame of the production line (not shown in the figure) and positioned to the side of the glass conveyor belt 30. Bearings 24 are mounted on opposite sides of each of the two mounting supports 21. The rotating shaft 22 passes through the inner ring of the bearing 24, allowing it to rotate freely relative to the mounting supports 21.

[0020] The free positioning wheel 23 is fitted onto the rotating shaft 22 with a clearance fit, and is fixed on both sides by positioning rings 25 and can rotate freely on the rotating shaft 22.

[0021] The design of the free positioning wheel 23 being able to rotate relative to the rotating shaft 22, and the rotating shaft 22 being able to rotate relative to the mounting bracket 21, achieves the following: when the frictional resistance is low, the free positioning wheel 23 rotates; when the frictional resistance is high, both the shaft 22 and the free positioning wheel 23 can rotate, ensuring that the free positioning wheel 23 can rotate a certain angle under different resistance conditions.

[0022] The central axis of the installed free positioning wheel 23 is higher than the upper surface of the glass conveyor belt 30 to ensure that the glass 40 can contact the free positioning wheel 23 after being lifted.

[0023] The free positioning wheel 23 consists of a hub and a friction layer. The hub can be made of metal or high-strength engineering plastic. A friction layer made of rubber is coated on its outer circumferential surface. This rubber layer not only provides friction to drive the positioning wheel to rotate, but also effectively cushions the impact of the glass. The outer circumferential surface of the free positioning wheel 23 is machined into a smooth cylindrical surface to avoid any scratches on the edges of the glass 40.

[0024] After being lifted by the positioning and lifting frame, the side of the glass 40 contacts and is positioned with the free positioning wheel 23. During the process of the robot lifting the glass 40 upward and disengaging it from the free positioning wheel 23, the free positioning wheel 23 is driven to rotate by friction, thereby changing the contact positioning area on its peripheral wall, so that the next piece of glass hits a new position, avoiding the formation of grooves due to contact at the same position each time, improving its service life, and preventing the glass from being stuck and damaged.

[0025] like Figure 2 As shown, the working process or principle of the glass stacking and positioning device of this utility model is as follows: First, glass 40 runs on glass conveyor belt 30 to the stacking station. Driven by cylinders or motors, the lifting mechanism rises from below the glass conveyor belt 30, passes through the gap between the conveyor belt rollers, smoothly lifts the glass 40, completely detaches it from the surface of the conveyor belt, and finally raises the glass 40 to a fixed height, at which the side of the glass 40 is in contact with the outer circumferential surface of the free positioning wheel 23.

[0026] Secondly, on the stable platform provided by the lifting mechanism 10, the glass 40 is pushed laterally, and its side impacts the outer circumferential surface of the free positioning wheel 23 until it can no longer move. At this point, the position of the glass 40 on the horizontal plane is precisely determined.

[0027] Then, the robotic arm (not shown in the figure) descends and vacuum-grabs the glass 40. As the robotic arm lifts the glass, a huge static friction force is generated between the edge of the glass and the rubber surface of the free positioning wheel 23. This friction force drives the free positioning wheel 23 to rotate randomly at an angle.

[0028] Finally, after the robotic arm carries the glass away, the lifting mechanism 10 descends and resets. At this point, the free positioning wheel 23 has rotated to a new angle, and the contact point on its circumference has changed. The system is ready to receive the next piece of glass, which will impact a completely new position on the circumference of the free positioning wheel 23.

[0029] The device of this utility model, through the design of friction-driven rotation during lifting, makes the entire circumference of the free positioning wheel 23 evenly utilized, thereby avoiding the situation of local dents and wear caused by repeated impacts on a single part, fundamentally solving the problem of glass jamming and breakage, and significantly extending the service life of the positioning device.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
