Description

Technical Field

[0001] The invention belongs to the technical field of glass processing, and in particular relates to a glass continuous laser polygonal hole production line. Background Art

[0002] The existing technology is to first position the glass against the edge, and then drive the laser head with the origin as the reference on the x\y\z axis to process the holes or edge defects on the glass according to the pre-imported graphics. The glass must be placed on the positioning edge by personnel or a mechanical arm. During the processing, the graphics and hole positions must be manually intervened, and after processing, it must be taken out manually or by a mechanical arm. The main problems are:

[0003] 1. Waste of manpower. Equipment operation must be carried out by personnel on site. The upstream edge grinding needs additional personnel to unload the sheets, and the downstream tempering needs additional personnel to load the sheets.

[0004] 2: Increased handling risk. Glass is a fragile item that is easily bumped. Once a little bit is knocked off, it becomes scrap and cannot be repaired or reused. Large glass requires several people to lift the upper and lower pieces at the same time, increasing the risk of injury.

[0005] 3: Increased risk of scratches. The positioning of the glass-supporting platform of the machine and the placement of the glass, as well as the dragging of the upstream glass during the process of being taken down from the shelf to the rack will cause small scratches on the glass, and scratches mean the glass will be scrapped.

[0006] 4: Low efficiency. During the processing, the up and down transportation of glass occupies 2 / 3 of the entire processing time. If it is a large glass, the loading and unloading time is even longer than the processing time of the glass. During the loading and unloading process, the machine head can only be in a waiting state, which wastes too much time.

[0007] 5: It is impossible to connect with upstream and downstream equipment, resulting in uncertainty in the rhythm of the entire workshop production process. Summary of the invention

A screw rod is provided inside the fixed cross bar 2, and an internal thread cooperating with the screw rod is provided on the slider 3, and one end of the screw rod is driven by a motor.

[0060] In this embodiment, the conveying device includes:

[0061] 4 roller racks;

[0062] A roller conveyor belt, the roller conveyor belt is arranged on a roller 4 frame at a certain inclination angle, and the roller 4 on the roller conveyor belt and a plurality of fixed cross bars 2 are arranged alternately in sequence;

[0063] A plurality of rotatable positioning wheels 5, the plurality of positioning wheels 5 are arranged at intervals along the transport direction of the roller frame 4, and are arranged on a side of the roller conveyor with a lower height, and the plurality of positioning wheels 5 are all located at the upper end of the roller conveyor;

[0064] A plurality of lifting drive mechanisms are provided, wherein the fixed end of the lifting drive mechanism is fixedly connected to the fixed base, and the drive end is fixedly connected to the roller frame.

[0065] In this embodiment, the roller conveyor belt and the roller frame 4 form an inclined angle of 11°.

[0066] Preferably, the surface of the roller 4 is made of nitrile rubber.

[0067] In this embodiment, the slider 3 is made of steel inside and wrapped with rubber outside.

[0068] Specifically, after the roller transfers the glass to the designated position, the roller descends and the glass is placed on the processing platform. The plane of the processing platform is within ±0.05mm. The glass is supported by a slider on the platform surface. The inside of the slider is 45# steel and the outside is covered with rubber to ensure that the glass is not scratched.

[0069] In this embodiment, the glass 1 laser cutter 6 comprises:

[0070] A crossbeam, which is slidably connected to the upper side of the fixed frame and moves along the X-axis direction;

[0071] The slide is slidably connected to the crossbeam and moves along the Y-axis direction;

[0072] The ram is slidably connected to the slide plate and moves along the Z-axis direction;

[0073] The laser host is installed on the slide, and the light output box and the galvanometer field lens are installed on the slide.

[0074] In this embodiment, the laser mainframe of the laser cutter 6 is installed on the Y axis, and the storage tank box and the galvanometer scene are installed on the Z axis, which can reduce the turning and loss of the optical path. The appearance design is also relatively reasonable.

[0075] In this embodiment, a dust collection integrated box 9 is installed below the laser cutter 6 .

[0076] In this embodiment, the positioning device includes:

[0077] An X-axis position detector 7, which is slidably disposed on one side of the fixing frame and is used to detect the X position of the glass 1;

[0080] The Z-axis length detector is arranged on the light output box body and is used to detect the height of the glass 1 to be tested.

[0081] Linear motors, linear guides, magnetic gratings, and optical fiber sensors are used to form X-axis length detectors, Y-axis length detectors, and Z-axis length detectors, which are used to detect the size and thickness of the glass and identify the glass in the software processing library. After identification, holes are processed according to the preset position size and hole type in the library. Linear motors, linear guides, magnetic gratings, and optical fiber sensors are used to form a glass position detection mechanism, which is used to detect the actual position of the glass after it travels. After feedback, the X-axis corrects the travel distance of the glass to ensure the accuracy of the glass travel, that is, to ensure the accuracy of the hole and hole position.

[0082] This equipment greatly promotes the application of laser in the field of glass, and then promotes the continuous optimization and upgrading of the field of laser itself. In terms of processing, 3 people punching holes can produce about 200 square meters of glass per day. Now laser punching can be completed by one person. Taking the shower room glass as an example, 7 holes are made per piece of glass. The glass is 1900*650=1.235 square meters. On average, each hole is 10 seconds, 10*7 / 60=1.2 minutes / piece, 50 pieces*8=400 pieces*1.235=494 square meters of glass per hour. The output ratio of personnel is 7.5 times that of the existing process. It greatly shortens the processing time, improves efficiency, and reduces scrap and loss.

[0083] Example 2

[0084] This embodiment provides a processing technology, using the glass continuous laser polygonal hole production line in embodiment 1, and the processing steps include:

[0085] S1. First, import the glass drawing to be processed into the glass library, edit the processing quantity and thickness, and start the equipment;

[0086] S2. The position detection head in the X-axis position detector is driven by a linear motor along the X-axis, and the magnetic grid counts and moves to the X origin of the glass processing. The glass is transported from the upstream equipment to the feeding section of the machine, and then transported by the rollers in the roller conveyor belt and moves close to the positioning wheel at the edge to the processing X origin and stops;

[0087] S3, the X-axis length detector is driven by a linear motor along the X-axis, and the magnetic grid counts to the end of the glass to detect the length of the glass. The Y-axis length detector is driven by a linear motor along the Y-axis, and the magnetic grid counts to the widest point of the glass to detect the width of the glass. The Y-axis length detector is driven by a motor to drive the ball screw, which drives the detection head to sense the glass and measure the glass thickness. Feedback to the computer, match the glass size in the preset library, and automatically load the processing graphics that meet the size;

[0088] S4, the X-axis position detector moves to the hole size, the glass is conveyed to the position detector by the conveyor roller, the roller stops after the X-axis position detector senses the glass, the roller frame as a whole is driven by the cylinder to lower the swing arm, the glass is placed on the working platform, and the X-axis position detector detects the X position of the glass after it is lowered again;

[0089] S5. If there is a deviation from the set value, the X slider is driven by the servo to drive the screw rod to compensate, and the Y and Z axes enter the hole position. The laser works, and the system controls the galvanometer to deflect the light through the field mirror to start processing the glass. After the processing is completed, the drum frame is driven by the cylinder swing arm to rise as a whole, and the drum is conveyed to the second hole position. The same as the previous process, the drum descends ---- detection position ---- compensation position ---- XYZ is in place --- start processing;

[0090] S6. After the glass hole processing is completed, it is transferred by the roller to the downstream cleaning machine for cleaning, and the entire glass processing is completed.

[0091] Preferably, there are 4 tables in total, namely, the first feeding table, the second feeding table, the first discharging table and the second discharging table. When the length of the glass is less than 1700MM, the glass is processed on the second feeding table and the first discharging table. The first feeding table can continuously load the glass and the second discharging table can continuously discharge the glass. The transmission and lifting between them are independent and do not interfere with each other, which greatly improves the efficiency.

[0092] The present invention is for the existing equipment currently used for laser drilling:

[0093] 1: It can be connected with the upstream equipment, and the glass can be directly transferred to this equipment after edge grinding and cleaning, with automatic detection and positioning, without the need for personnel to carry, no need to unload the glass upstream and load the glass downstream, thus reducing labor.

[0094] 2: There is no risk in transportation. The equipment is directly transferred to this device, so there is no risk in transportation.

[0095] 3: Because it does not need to be transported or taken off the shelf, the surface of the conveying roller of this equipment is made of nitrile rubber, which will not scratch the glass, the scrap rate is reduced, and the qualified rate is also improved.

[0096] 4: Because the handling process is reduced, the efficiency can be increased by 2 / 3. Laser drilling does not require the replacement of drilling tools, and the efficiency can also be improved. It can also process holes of various shapes and realize multiple processing on one machine, reducing the handling, positioning, and other processes, greatly improving work efficiency.

[0097] 5: It can be connected with upstream and downstream, and can transmit graphics through ERP data to directly process the ordered glass as required, greatly reducing the error rate and improving processing efficiency.

[0098] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
