Description

Technical Field

[0001] The present invention relates to the technical field of glass processing, and particularly to a positioning and drilling system for processing door and window glass. Background Art

[0002] With the upgrading of the functional requirements for door and window glass in the construction and home furnishing industries, the glass drilling process has gradually developed towards large aperture, high precision, and complex hole positions. However, the existing glass automatic drilling systems have significant technical bottlenecks, restricting the processing efficiency and the yield of finished products.

[0003] When the existing glass automatic drilling machine is used to drill holes in door and window glass, it usually adopts a single-piece sequential processing mode, and the processes of glass loading, unloading, positioning, and resetting need to be repeatedly executed. Especially in the scenarios of multi-specification small batches or sparse hole positions, the comprehensive utilization rate of the equipment is significantly reduced; and the existing pressing device usually uses a single rigid pressing ring to press the upper surface of the glass. When drilling the edge of the glass, only part of the bottom end of the rigid pressing ring will contact the upper surface of the glass. Due to the reduction of the contact area, the pressing force is directly insufficient, resulting in slight displacement of the glass under the acting force of drilling, further aggravating the hole position deviation, and significantly increasing the risk of chipping, leading to the problems that the glass is prone to slide or break during the drilling process. Summary of the Invention

[0025] The conveying and positioning mechanism 5 includes positioning parts 51 symmetrically arranged on the left and right of the workbench 1. The positioning part 51 includes positioning groups symmetrically arranged on the left and right of the workbench 1. The positioning group includes two upper and lower slide rails commonly installed on the inner walls at the front and rear ends of the workbench 1. Two front and rear electric sliders 511 are slidably installed on the slide rails. Rubber clamping plates 512 are installed at both the left and right ends of the electric slider 511.

[0026] The conveying and positioning mechanism 5 further includes a plurality of conveying parts 52 commonly arranged on the inner walls at the front and rear ends of the workbench 1. The plurality of conveying parts 52 are evenly arranged from left to right. The conveying part 52 includes a plurality of conveying rollers 521 commonly installed through rotation on the inner walls at the front and rear ends of the workbench 1. The plurality of conveying rollers 521 are evenly arranged from top to bottom.

[0027] During specific implementation: When loading materials, first control the synchronous rotation of the multiple conveying rollers 521 on each layer, and use an external automatic glass loading device to convey the multiple pieces of glass to be drilled to the multiple conveying rollers 521 on each layer respectively. The multiple conveying rollers 521 on each layer will jointly drive the corresponding glass to move towards the middle of the workbench 1. During this period, use an external alignment device to align the left and right ends of the multiple pieces of glass. Then control the corresponding multiple electric sliders 511 to drive the corresponding rubber clamping plates 512 to approach each other respectively, so as to achieve the effect of jointly clamping the multiple pieces of glass by the rubber clamping plates 512 on the front and back sides. Adjust the front and back positions of the multiple pieces of glass through the corresponding multiple electric sliders 511, and adjust the left and right positions of the multiple pieces of glass through the multiple conveying rollers 521 on each layer. Until the positions of the holes to be drilled on the multiple pieces of glass correspond to the glass drill bit 4, control the multiple conveying rollers 521 on each layer to stop rotating. When the single-point drilling of the multiple pieces of glass is completed, control the multiple conveying rollers 521 and the multiple electric sliders 511 on each layer to cooperate, and the positions of the multiple pieces of glass can be jointly adjusted to facilitate the subsequent drilling work. It should be noted that when the multiple conveying rollers 521 drive the corresponding glass to move respectively, under the action of the compression spring, the multiple pieces of glass will respectively squeeze the corresponding elastic telescopic sleeves 62, making them move upward to avoid blocking the movement of the glass, and cooperate with the annular support base 63 to jointly support the upper and lower end faces of the corresponding glass.

[0028] When drilling, control the hollow lifting rod 3 to drive the glass drill bit 4 to continuously move downward through the automatic drilling machine 2. When the glass drill bit 4 moves to the position above the uppermost glass, control the glass drill bit 4 to rotate to perform the drilling work. Until the glass drill bit 4 completes the drilling work on this glass, control the hollow lifting rod 3 to stop moving downward through the automatic drilling machine 2. It should be noted that under the action of the compression spring, the contact plate 723 is initially located at the upper position of the rectangular installation groove, and the glass drill bit 4 is usually a tubular structure, and its lower end is coated with a diamond coating so that the pipe wall has a certain thickness. The contact plate 723 initially extends a part out of the inner wall of the annular support base 63 and corresponds to the inner wall of the diamond coating of the glass drill bit 4. In addition, the N pole of the two-pole magnet 728 is above the S pole, and the magnetic attraction inclined baffle 721 is the S pole. At this time, the S pole of the two-pole magnet 728 corresponds to the magnetic attraction inclined baffle 721. Under the action of the same-sex repulsion, every two adjacent magnetic attraction inclined baffles 721 are in a state of approaching and blocking each other.

[0029] During this period, the circular waste obtained after drilling the uppermost glass will slide freely downward along the inner wall of the annular support base 63 and fall on the two magnetic attraction inclined baffles 721 in the front and back, and slide out of the annular support base 63 along the inclined direction of the material guiding chute 71, so as to achieve the effect of discharging the circular waste. It should be noted that due to the certain thickness of the glass and the limited distance between the glass and the corresponding annular support base 63, the circular waste will not have a large-angle flip during the free fall, and thus will not directly fall through the gap between the two magnetic attraction inclined baffles 721.

[0030] When continuing to drill subsequent glass, repeat the process of controlling the hollow lifting rod 3 by the automatic drilling machine 2 to drive the glass drill bit 4 to continuously move downward. When the glass drill bit 4 moves to the position above the corresponding glass, control the glass drill bit 4 to rotate to drill it. After the glass drill bit 4 completes the drilling work on this glass, control the hollow lifting rod 3 by the automatic drilling machine 2 to stop moving downward. During the downward movement of the glass drill bit 4, it will squeeze the parts of the corresponding front and rear contact plates 723 extending out of the inner wall of the annular support base 63, driving them to move downward synchronously. At the same time, under the combined action of the front and rear wedge plates 724, triangular plates 725, and extended wedge plates 726, the front and rear contact plates 723 will move away from each other, enabling the glass drill bit 4 to move downward smoothly. And when the front and rear contact plates 723 move downward, they will drive the two-pole magnets 728 to slide downward along the connecting chute through the connecting slide bar 727 until the N poles of the two-pole magnets 728 correspond to the magnetic attraction inclined baffle plates 721. Under the action of opposite-sex attraction, the front and rear magnetic attraction inclined baffle plates 721 will move away from each other and tightly adsorb to the N poles of the corresponding two-pole magnets 728, thereby achieving the effect that the glass drill bit 4 can continue to move downward smoothly and drill subsequent glass.

[0031] Whenever the glass drill bit 4 finishes drilling a piece of glass, control the hollow lifting rod 3 by the automatic drilling machine 2 to drive the glass drill bit 4 to continue moving downward. At this time, multiple annular magnets 831 respectively correspond to the upper and lower horizontal sections of the corresponding C-shaped frames 811. The upper and lower horizontal sections of the corresponding C-shaped frames 811 will slide out along the corresponding rectangular through holes one and tightly adsorb to the inner walls of the corresponding annular magnets 831. Whenever the glass drill bit 4 rotates at high speed, the hollow lifting rod 3 will drive multiple C-shaped frames 811 to rotate synchronously, and multiple C-shaped frames 811 will drive the corresponding upper and lower trapezoidal grinding plates 812 to rotate synchronously, thereby achieving the effect of chamfering and deburring the upper and lower ends of the glass hole. At the same time, multiple T-shaped weighted grinding plates 821 will correspond to the inner wall of the glass hole and, under the centrifugal force of the high-speed rotation of the hollow lifting rod 3, slide out along the corresponding guiding through holes respectively, thereby achieving the effect of chamfering and deburring the inner wall of the glass hole. After all the required glass is drilled, control the hollow lifting rod 3 by the automatic drilling machine 2 to drive the glass drill bit 4 to continuously move upward to return to its original position, and then control the corresponding multiple electric sliders 511 to drive the corresponding rubber clamping plates 512 to move away from each other to return to their original positions, so as to separate multiple pieces of glass. Finally, control the multiple conveying rollers 521 on each layer to rotate synchronously again, and the completed drilled multiple pieces of glass can be taken out by an external glass picking device.

[0032] It should be noted that whenever the glass drill bit 4 stops rotating, under the action of the compression spring, multiple T-shaped weight grinding plates 821 will return to their original positions to avoid damaging the inner wall of the glass hole. And whenever the glass drill bit 4 moves up and down, after losing the magnetic attraction of the annular magnet 831, under the action of the compression spring, multiple C-shaped frames 811 will drive the corresponding upper and lower trapezoidal grinding plates 812 to return to their original positions to avoid hindering the up and down movement of the glass drill bit 4.

[0033] In summary, the present application adopts the following advantages: Advantage 1: The conveying and positioning mechanism 5 in the present application conveys glass through multiple conveying rollers 521 on each layer, adopts a multi-piece fixed-point continuous drilling processing mode, does not need to repeatedly execute the processes of glass loading, unloading, positioning and resetting, significantly improves the comprehensive utilization rate of the equipment and the drilling efficiency, and can effectively improve the coaxiality and installation accuracy of glass drilling in the same batch.

[0034] Advantage 2: When multiple conveying rollers 521 drive the corresponding glass to move to the positions of the elastic telescopic sleeves 62 and the annular support seats 63 respectively, under the action of the compression spring, multiple pieces of glass will respectively squeeze the corresponding elastic telescopic sleeves 62 to move them upward, avoiding blocking the movement of the glass, and cooperate with the annular support seats 63 to jointly support and tightly press the upper and lower end faces of the corresponding glass, avoiding the problem that when using a single rigid pressing ring to tightly press the upper surface of the glass, only part of the bottom end of the rigid pressing ring will contact the upper surface of the glass when drilling the edge of the glass, resulting in easy sliding or cracking of the glass during the drilling process.

[0035] Advantage 3: Every two adjacent magnetic attraction inclined baffles 721 are in a state of being close to each other and blocking. The circular waste obtained after drilling the uppermost glass will slide freely downward along the inner wall of the annular support seat 63 and fall on the two adjacent magnetic attraction inclined baffles 721, and slide out of the annular support seat 63 along the inclined direction of the material guiding chute 71, so as to achieve the effect of discharging the circular waste, avoiding falling onto the lower-layer glass and further affecting the drilling work of the lower-layer glass.

[0036] Advantage 4: When continuing to drill the subsequent glass, during the process of controlling the glass drill bit 4 to move downward, it will squeeze the parts of the corresponding two abutting plates 723 extending out of the inner wall of the annular support seat 63, driving them to move downward synchronously. At the same time, under the combined action of the two front and rear wedge-shaped plates 724, the triangular plate 725 and the extended wedge-shaped plate 726, the two front and rear abutting plates 723 will move away from each other, so that the glass drill bit 4 can move downward smoothly. And when the two front and rear abutting plates 723 move downward, they will drive the two-pole magnet 728 to slide downward along the communicating chute through the connecting slide bar 727 until, under the action of opposite-sex attraction, the two adjacent magnetic attraction inclined baffles 721 will move away from each other, thus achieving the effect that the glass drill bit 4 can continue to move downward smoothly and drill the subsequent glass.

[0037] Advantage Five: Whenever the glass drill bit 4 drills a hole in a piece of glass, the automatic drilling machine 2 controls the hollow lifting rod 3 to drive the glass drill bit 4 to move downward until the plurality of annular magnets 831 respectively correspond to the upper and lower horizontal sections of the corresponding U-shaped frame 811. The upper and lower horizontal sections of this U-shaped frame 811 will slide out along the corresponding rectangular through holes and be tightly adsorbed on the inner walls of the corresponding annular magnets 831. Whenever the glass drill bit 4 rotates at a high speed, the hollow lifting rod 3 will drive the plurality of U-shaped frames 811 to rotate synchronously, and the plurality of U-shaped frames 811 will drive the corresponding upper and lower trapezoidal grinding plates 812 to rotate synchronously, so as to achieve the effect of chamfering and deburring the upper and lower ends of the glass hole.

[0038] Advantage Six: Whenever the glass drill bit 4 drills a hole in a piece of glass, the plurality of T-shaped weighted grinding plates 821 will correspond to the inner wall of the glass hole and slide out along the corresponding guiding through holes respectively under the centrifugal force of the high-speed rotation of the hollow lifting rod 3, so as to achieve the effect of chamfering and deburring the inner wall of the glass hole and effectively improve the drilling quality and accuracy.
