Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a CNC numerically controlled glass processing center for manufacturing tempered glass. Background Art

[0002] Tempered glass is a type of safety glass. In fact, tempered glass is a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc.

[0003] A document with publication number CN216178615U was retrieved and disclosed as a CNC processing device for aviation plexiglass. Its beneficial effects state that "by pulling the second pulling member outward, the second slide bar can be driven to disengage from the first slide groove, wherein the second return spring is stretched, and the elastic action of the first return spring can drive the first slide bar to slide downward, thereby driving the fixed plate and the protective cushion layer to move downward, and through the joint action of the first return spring, the first slide bar, the fixed plate and the protective cushion layer, the aviation plexiglass can be quickly fixed on the CNC processing table." It can be seen that the fixation of the glass still needs to be done manually by the operator.

[0004] In the above-mentioned prior art, the glass is still fixed by manual pressing by the operator, which has a low degree of automation and increases the intensity of manual labor. The pressing method will also block some areas of the glass. Once the position needs to be processed, re-clamping is avoided, which is time-consuming and labor-intensive. In addition, the above-mentioned prior art lacks a waste collection device during processing, and the waste generated during processing will endanger the health of on-site personnel.

Detailed implementation

[0027] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0028] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0029] As Figures 1-6 shown, the present invention provides a CNC numerical control glass processing center for tempered glass manufacturing, including a CNC machining table 100 and a CNC numerical control machining equipment 200 arranged on the CNC machining table 100 for glass processing. It is characterized in that: a vacuum adsorption table 300 is installed on the CNC machining table 100, and a dust suction assembly 400 is arranged on the back of the vacuum adsorption table 300;

[0030] A number of mutually connected vacuum chambers 301 are opened in the vacuum adsorption table 300. A top plate 302 is fixedly arranged above each vacuum chamber 301. Adsorption holes 303 are evenly distributed on the top plate 302. A number of longitudinal grooves 304 are opened on the top of the vacuum adsorption table 300. Each longitudinal groove 304 is located between two adjacent vacuum chambers 301. Two sets of clamping assemblies 500 with opposite directions are arranged in each longitudinal groove 304. An accommodation groove 305 communicating with the longitudinal groove 304 is opened on the vacuum adsorption table 300. A driving assembly 600 for driving the clamping assembly 500 to move is installed in the accommodation groove 305.

[0031] In this embodiment, the driving assembly 600 includes a motor 601 installed in the front accommodation groove 305. A worm 602 is fixedly connected to the output shaft of the motor 601. A bidirectional screw 603 is rotatably arranged in each longitudinal groove 304. A worm gear 604 meshing with the worm 602 is fixedly sleeved on the front end of the bidirectional screw 603. Two nuts 605 are threadedly connected to the bidirectional screw 603 and are arranged at intervals along the length direction of the bidirectional screw 603.

[0032] In this embodiment, the clamping assembly 500 includes a moving plate 501 fixedly sleeved on the outer side of the nut 605. A contact plate 502 is arranged on the moving plate 501. A plurality of sliding rods 503 penetrating through the moving plate 501 are fixedly connected to the side surface of the contact plate 502. A spring 504 sleeved on the outer side of the sliding rod 503 is fixedly connected between the contact plate 502 and the moving plate 501. The spring 504 enables the contact plate 502 to have a certain pre-tightening force when contacting the glass, and also enables the contact plate 502 to have a buffering effect when contacting the glass, effectively avoiding the situation of glass damage caused by excessive clamping force.

[0033] In this embodiment, a limit block 505 is fixedly arranged at one end of the sliding rod 503 far from the contact plate 502. A protective cushion layer 506 is fixedly connected to one end of the contact plate 502 far from the sliding rod 503. The protective cushion layer 506 protects the contact between the contact plate 502 and the tempered glass.

[0034] In this embodiment, the moving plate 501 has a "Z" - shaped structure. The width of the moving plate 501 matches the width of the longitudinal groove 304. The moving plate 501 displaces along the length direction of the longitudinal groove 304. The shape and width of the moving plate 501 can ensure its displacement along the length direction of the longitudinal groove 304, playing a limiting role.

[0035] In this embodiment, the dust suction assembly 400 includes a dust suction box 401. A dust suction fan 402 is installed on the back of the dust suction box 401. A sealed drawer 403 partitioning the dust suction box 401 is inserted through the top plate 302 of the dust suction box 401. A filter cloth 404 is fixedly arranged in the sealed drawer 403. The dust suction fan 402 generates suction to suck the waste chips generated during processing onto the filter cloth 404 in the dust suction box 401, realizing the dust suction function, avoiding pollution of the processing environment, and avoiding health hazards to operators caused by waste chips.

[0036] In this embodiment, lifting blocks 405 are fixedly connected to both sides of the dust suction box 401. Main bevel gears 606 are fixedly arranged at the rear ends of the bidirectional screw rods 603. A vertical rotating shaft 607 and a vertical screw rod 608 that match the bidirectional screw rods 603 are rotatably arranged on the CNC machining table 100. A secondary bevel gear 609 that meshes with the main bevel gear 606 is fixedly connected to the top end of the vertical rotating shaft 607. A main turntable 610 is fixedly sleeved on the outer wall of the vertical rotating shaft 607 below the secondary bevel gear 609. A secondary turntable 611 is fixedly sleeved on the outer wall of the vertical screw rod 608. A belt 612 is arranged for transmission between the secondary turntable 611 and the main turntable 610. When the bidirectional screw rod 603 rotates to drive the main bevel gear 606, the vertical rotating shaft 607 is driven by the secondary bevel gear 609 to make the main turntable 610 rotate. The main turntable 610 drives the secondary turntable 611 through the belt 612 to drive the vertical screw rod 608 to rotate. The vertical screw rod 608 drives the lifting block 405 to drive the dust suction box 401 to rise.

[0037] In this embodiment, the diameter of the main turntable 610 is different from that of the secondary turntable 611. A limit plate 613 is fixedly arranged at the top end of the vertical screw rod 608. The limit plate 613 limits the lifting block 405 to prevent the lifting block 405 from separating from the vertical screw rod 608. And the diameters of the main turntable 610 and the secondary turntable 611 are set according to the actual situation to adjust the transmission ratio so that the inlet of the dust suction box 401 is located above the vacuum suction disc during the processing, ensuring that the dust suction effect can be achieved regardless of the width of the tempered glass during processing.

[0038] Usage method and working principle of this device:

[0039] When this device is in use, first place the tempered glass to be processed on the vacuum suction table 300. The motor 601 drives the worm 602 to make the worm gear 604 rotate. The worm gear 604 makes the bidirectional screw rod 603 rotate. Under the screw thread drive of the bidirectional screw rod 603, the two nuts 605 move relatively and drive the moving plate 501, so that the contact plate 502 on the moving plate 501 pre-contacts the tempered glass. By the elastic action of the spring 504, when the contact plate 502 contacts the tempered glass, it has a certain moving space, which has the effect of straightening and positioning the tempered glass. As the moving plate 501 moves, the spring 504 assembly is compressed, and the elastic force of the spring 504 acts on the contact plate 502 until the tempered glass is clamped, which can effectively avoid the situation of damage to the tempered glass caused by excessive clamping force.

[0040] After the clamping of the tempered glass is completed, the vacuum adsorption table 300 is externally connected to a vacuum generator to evacuate the vacuum chamber 301, creating a negative pressure environment at the adsorption holes 303 on the top plate 302 to adsorb the tempered glass. Through the alignment, positioning, and clamping of the clamping assembly 500 and in cooperation with the adsorption of the vacuum adsorption table 300, the tempered glass is fixed. Compared with the manual operation method in the prior art, the automation degree and production efficiency are improved. Moreover, the vacuum adsorption method will not block the upper part of the tempered glass, and the situation of re-clamping will not occur, saving time and effort.

[0041] While the tempered glass is being fixed, when the bidirectional screw 603 rotates, it drives the main bevel gear 606 to rotate and makes the vertical rotating shaft 607 rotate through the sub-bevel gear 609. The rotation of the vertical rotating shaft 607 makes the main turntable 610 rotate and drives the sub-turntable 611 to drive the vertical screw 608 to rotate through the belt 612. The vertical screw 608 drives the lifting block 405 to drive the dust collection box 401 to rise. When the fixing of the tempered glass is completed, the height of the dust collection box 401 also rises above the vacuum adsorption table 300. During processing, the dust collection fan 402 works to generate suction, sucking the waste chips generated during processing onto the filter cloth 404 in the dust collection box 401 to achieve the dust collection function, avoiding pollution of the processing environment and preventing the waste chips from causing health hazards to the operators.

[0042] The above is only a preferred embodiment of the present invention and is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
