Description

Technical Field

[0001] The utility model belongs to the technical field of automatic optical glass cutting devices, and particularly relates to a breaking assistance device in an online automatic optical glass block cutting device, which is used for assisting in breaking after the optical glass thick plate is divided. Background Art

[0002] After the optical glass is formed and annealed, the glass needs to be separated to form block plates for supply.

[0003] Currently, in this industry, manual scribing is carried out. According to the annealing situation and operation experience, water is dipped at the scribed line, and then a rubber mallet is used to strike and break after cooling. There are problems such as uneven cutting size and high labor costs.

[0004] CN 117776513A solves the above operation problems. It adopts a glass product displacement follow-up scanning, a synchronization mechanism, and corresponding scribing, cooling, and pressing mechanisms to automatically divide the formed glass plate. While saving labor, it ensures the consistency of products. The synchronization mechanism includes a synchronous moving guide rail plate, a cutting edge support plate, and a photoelectric switch. The photoelectric switch is installed on the side of the synchronous moving guide rail plate at the front end of the falling of the pre-cut glass block, and the cutting edge support plate is installed on the synchronous moving guide rail plate corresponding to the fracture surface of the pre-cut glass block. In this way, a receiving material drop T is formed between the height of the cutting edge support plate and the synchronous moving guide rail plate. As the thickness of the plate increases (for example, the thickness ≥ 28 mm), due to reasons such as the inability of the internal stress of the glass to be quickly released, there will be more or less chipping or burrs at the bottom of the cutting position of the glass, which will affect the appearance quality of the supplied products and reduce the yield rate of the products; sometimes it will affect the later automatic weighing, labeling, and palletizing operations due to incomplete cutting, and affect the normal production process. Content of the Utility Model

[0005] In order to overcome the above technical problems, the utility model provides a breaking assistance device for automatic cutting of optical glass plates, which is used in an online automatic optical glass block cutting device to avoid chipping or burrs caused by insufficient cutting during the cutting of relatively thick optical glass blocks.

[0006] The technical solution of the present utility model is: an assisting breaking device for automatic cutting of optical glass sheet materials, which is used in an automatic cutting device for optical glass sheet materials, and includes a synchronous moving guide rail plate, a cutting edge support plate for the lower cut, and a photoelectric switch. The photoelectric switch is installed on the side of the synchronous moving guide rail plate where the front end of the glass block to be cut downward falls. The cutting edge support plate for the lower cut is installed on the synchronous moving guide rail plate corresponding to the fracture surface of the glass block to be cut downward. Its characteristics are: it also includes a roller assembly that can move up and down. The roller group in the roller assembly is located at the top of the roller assembly, and the slope formed by each roller in the roller group is matched with the slopes formed when the front end and the fracture surface of the glass block to be cut downward are respectively located on the synchronous moving guide rail plate and the cutting edge support plate for the lower cut; the roller assembly is installed below the synchronous moving guide rail plate; a gap is provided on the synchronous moving guide rail plate for cooperating with the up and down movement of the roller assembly.

[0007] When the thick optical glass on the production line starts to be divided under the action of the upper pressure, the front end of the glass block to be cut downward drops vertically under the action of gravity. After the photoelectric switch installed on the synchronous moving guide rail plate senses the position change, the roller assembly rises from below the synchronous moving guide rail plate, and the roller group of the roller assembly passes through the gap of the synchronous moving guide rail plate and contacts the glass block to be cut downward, instantly lifting the product. This operation reduces the tearing of gravity on the lower end of the fracture surface of the glass block to be cut downward, and gives a boost from below to help the glass release the final stress within the best time, so as to fully separate the glass from the production line.

[0008] In the technical solution of the present utility model, the roller assembly is installed and fixed below the synchronous moving guide rail plate through a fixing plate.

[0009] In the technical solution of the present utility model, the roller assembly is composed of a cylinder, a connecting piece, and a roller group; the piston rod of the cylinder faces upward and is connected to the bottom of the connecting piece, and the roller group is installed on the upper surface of the connecting piece.

[0010] In the technical solution of the present utility model, the roller group is a set of two, distributed in the middle section of the connecting piece, and the two rollers are installed at both ends of the upper surface of the connecting piece.

[0011] In the technical solution of the present utility model, the roller group is two sets of four, and the four rollers are symmetrically installed at the four corners of the upper surface of the connecting piece.

[0012] In the technical solution of the present utility model, the slope angle of the roller group formed by each roller in the roller group is greater than the slope angle of the glass block when the front end and the fracture surface of the glass block to be cut downward are respectively located on the synchronous moving guide rail plate and the cutting edge support plate for the lower cut.

[0013] In the technical solution of the present utility model, the difference between the slope angle of the roller group and the slope angle of the glass block is 2 degrees to 5 degrees.

[0014] In the technical solution of the present utility model, the roller group is composed of a small roller shaft, a bearing and a small bearing seat; the small roller shaft is fixedly connected to the small bearing seat fixed on the connecting piece through the bearing.

[0015] In the technical solution of the present utility model, the gap is a rectangular through hole.

[0016] In the technical solution of the present utility model, the distance between the fracture surface of the pre-cut glass and the vertical surface near the lower cut of the lower cut blade support plate is 5 mm to 15 mm.

[0017] The present utility model adds a fracture assisting device on the basis of the patent of CN 117776513A to facilitate the auxiliary lower cut of thick glass. Due to the pressure of the automatic lower cut device from top to bottom on the thick glass on the production line, the stress on the upper surface of the glass starts to be released from the cooled scribed part. One end of the glass far from the fracture surface droops downward under the action of gravity, and the glass is divided into two. The photoelectric switch fixed on the synchronous moving guide plate senses the downward movement of the glass and sends a signal after an interval of 2 - 3 seconds. The roller combination with a height difference rises from the middle gap of the synchronous moving guide plate, and the roller group gives an upward external force to the pre-cut glass from below to promote the complete separation of the glass. This external force does not need to be large, and the direction is preferably as consistent as possible with the inclination direction of the glass at this time, and the end close to the pre-fracture surface is slightly higher so that it can slide forward. The difference between the slope angle of the roller group and the slope angle of the glass block is preferably 2 degrees to 5 degrees.

[0018] The present utility model has the characteristics of simple structure and convenient operation, and is mainly used to solve the auxiliary separation operation during the automatic cutting and lower cut of thick optical glass plates. Brief Description of the Drawings

Detailed implementation mode

[0025] The following will further elaborate on the present utility model in conjunction with the attached drawings. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0026] As Figures 1 to 5 shown. An embodiment of an assisting cutting device for automatically cutting optical glass plates of the present utility model includes a synchronous moving guide rail plate 3, a lower cutting edge support plate 6, a photoelectric switch 5, and a roller assembly 2 in the automatic cutting device for optical glass plates. Among them: The roller assembly 2 can move up and down and is installed below the synchronous moving guide rail plate 3. The roller group 23 in the roller assembly 2 is located at the top, and the slope formed by each roller in the roller group 23 matches the slopes formed when the front end and the fracture surface of the pre-lower cut glass block 4 are respectively located on the synchronous moving guide rail plate 3 and the lower cutting edge support plate 6; A rectangular through hole is opened in the middle of the synchronous moving guide rail plate 3 corresponding to the blanking position to form a gap, so as to provide enough space for the roller group 23 at the top of the roller assembly 2 to move up and down.

[0027] The roller assembly 2 includes a cylinder 21, a connecting piece 22, and a roller group 23. The roller group 23 includes front and rear rollers; The cylinder 21 is a rod-type cylinder and is vertically installed at the lower end of the synchronous moving guide rail plate 3 through a fixing plate 8. The position of the piston rod of the cylinder 21 is directly below the gap in the middle of the synchronous moving guide rail plate 3. The piston rod of the cylinder 21 is connected to the connecting piece 22, and the front and rear rollers of the roller group 23 are respectively installed at both ends of the upper surface of the connecting piece 22.

[0028] The roller group 23 includes a small roller shaft 231, a bearing, and a small bearing seat 232. The small roller shaft 231 is fixedly connected to the small bearing seat 232 fixed on the upper surface of the connecting piece 22 through a rolling bearing.

[0029] To achieve the assisting cutting function for automatically cutting thick glass, the upper surface of the connecting piece 22 can be implemented in two structures.

[0030] One: There is a height difference at both ends of the upper surface of the connecting piece 22, and two rollers with the same structure are installed at both ends of the upper surface of the connecting piece 22. Due to the height difference of the connecting piece 22, the two roller groups 23 will form a roller group slope angle α with the horizontal.

[0031] The other two types: The two ends of the upper surface of the connecting member 22 are horizontal, while the heights of the rollers installed at the two ends of the upper surface of the connecting member 22 are different, and a slope angle α of the roller group will be formed due to the height difference and the horizontal level.

[0032] The slope angle α of the roller group formed above must be greater than the slope angle β of the glass block when the front end of the pre-cut glass block and the fracture surface are respectively located on the synchronous moving guide plate and the lower cutting edge support plate.

[0033] Under the pressure of the automatic lower cutting device from top to bottom on the thick glass on the production line, the stress on the upper surface of the glass starts to be released from the cooled scribed part. One end of the glass far from the lower cutting section droops downward under the action of gravity, and the glass will be divided into two. The photoelectric switch 5 fixed on the synchronous moving guide plate 3 senses the downward movement of the glass and sends a signal after an interval of 2 - 3 seconds. The roller combination 2 with a height difference rises from the middle gap of the synchronous moving guide plate 3, and the roller group 23 gives an upward external force to the pre-cut glass from below to promote the complete separation of the glass. This external force does not need to be large, and the direction should be as consistent as possible with the inclination direction of the glass at this time, and the end closer to the section is slightly higher so that it can slide forward.

[0034] The difference between the slope angle α of the roller group and the slope angle β of the glass block is preferably 2 degrees to 5 degrees.

[0035] The roller group 23 is composed of two rollers, which are distributed in the middle section of the connecting member 22 and are parallel to the discharging direction of the glass plate.

[0036] The roller group 23 can also be composed of four rollers, which are symmetrically distributed at the four corners of the connecting member 22.

[0037] This assisting cutting device may not work when producing thinner glass, and is only enabled when dealing with thicker glass that is not easy to be completely cut.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
