[0030] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "horizontal", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention. They cannot indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] See also Figure 1 and Figure 2 The first embodiment of the utility model provides a cutting and separation system for the primary processing of automobile side window glass, comprising: a frame 1, a sheet conveying device 2, a limiting device 6, a cutting device 3 and a lifting device;

[0032] The glass transmission device 2 is arranged on the frame 1, and includes a first transmission shaft group 21 and a second transmission shaft group 22. The first transmission shaft group 21 and the second transmission shaft group 22 are arranged in sequence along the glass transmission direction. Both transmission shaft groups are composed of a plurality of transmission shafts and are independently driven for transmitting glass.

[0033] The cutting device 3 includes a horizontal module and a cutting assembly. The horizontal module is arranged above the sheet conveying device 2, and its two ends are connected to the frame 1 through a first fixed frame 31. The cutting assembly is arranged on the horizontal module and can move along the vertical glass transmission direction. The cutting assembly includes a movable plate 32 and a cutting knife 33. The movable plate 32 is arranged on the horizontal module and can move along the vertical glass transmission direction. The cutting knife 33 is arranged on the movable plate 32 through a cutting drive cylinder, and its cutting end points to the jacking device below.

[0034] The lifting device includes a push rod 4 and a driving assembly 5. The push rod 4 is arranged between the first transmission shaft group 21 and the second transmission shaft group 22 of the film transmission device 2, is located below the cutting knife 33, and extends along the cutting track direction of the cutting knife 33. The driving assembly 5 is arranged below the push rod 4. The bottom of the driving assembly 5 is connected to the frame 1 through a bracket. The driving end of the driving assembly 5 is connected to the push rod 4 to drive the push rod 4 to rise and fall.

[0035] The limiting device 6 includes a crossbeam and a limiting assembly. The crossbeam is arranged above the film transmission device 2. Both ends of the crossbeam are connected to the frame 1 through a second fixing frame. At least one lifting module is arranged below the crossbeam. The limiting assembly is slidably arranged on the lifting module. The limiting assembly includes a connecting plate and a plurality of limiting columns 61. The connecting plate is arranged on a slider of the lifting module. Each limiting column 61 is arranged side by side below the connecting plate.

[0036] When the glass is transmitted, the limit device 6 is in a low position, and the glass is blocked when it reaches the limit column 61, that is, the glass reaches the cutting position. After that, the sheet conveying device 2 stops transmitting, the limit column 61 rises and retreats, the cutting device 3 starts, the cutting knife 33 moves downward, and the top rod 4 moves upward. The glass is slightly lifted, and the cutting knife 33 moves horizontally to cut the glass. The two sections of glass are naturally separated due to their own weight. After that, the second transmission shaft group 22 starts to transmit the cut glass for a distance to keep a safe distance between it and the original glass.

[0037] Specifically, the cutting knife 33 is a mechanical cutting knife, which has the advantage of high cutting accuracy. A laser cutting knife, a water jet cutting knife or a diamond roller cutting knife may also be used. The selection of the cutting knife needs to comprehensively consider factors such as the type, thickness, shape, cutting accuracy, and speed of the glass.

[0038] A sensor is also provided on the movable plate 32, located near the cutting knife 33, for identifying the edge position of the glass;

[0039] When the cutting device 3 is started, the movable plate 32 moves horizontally until the sensor detects the edge of the glass. Then, the cutting knife 33 moves downward and the top rod 4 moves upward. The cutting knife 33 cuts the glass at the top of the top rod 4 until the sensor detects the edge of the other side of the glass. Then, the cutting knife 33 rises and retreats, the top rod 4 falls and retreats, and the second transmission shaft group 22 starts to transmit the cut glass for a distance.

[0040] Specifically, the sensor uses a photoelectric sensor to detect the edge of the glass. A laser ranging sensor, a visual sensor or other contact sensors may also be used. The sensor can be selected and optimized according to specific cutting requirements and application scenarios.

[0041] In this embodiment, the top of the top rod 4 is designed as a platform with a width of 3 mm. The cut glass falls on the platform, the force is evenly applied, and the cut is smoother. If the top is designed as a wider platform, the glass next to the cutting line will stick to more glass powder, causing dust scratches.

[0042] The beneficial effects of the cutting and separation system for primary processing of automobile side window glass of the utility model are:

[0043] 1. A liftable top rod is designed under the cutting assembly. The glass is slightly lifted with the top rod so that the glass falls on the top rod. The cutting process is uniformly stressed and the cutting is smooth, which not only ensures the strength and durability of the glass, but also improves the appearance of the glass.

[0044] 2. After cutting, the two pieces of glass are naturally separated by their own weight, and the mechanical stress at the fracture is small, which reduces the risk of glass breakage during subsequent processing and use;

[0045] 3. The equipment has a simple structure, and cutting and separation are carried out simultaneously, which makes the manufacturing cost low and the efficiency high. The above description is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process transformation made by using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
