Description

Technical Field

[0001] This utility model relates to the field of glass cover drilling technology, specifically a drilling device for glass covers. Background Technology

[0002] Drilling is a crucial step in the production of glass pot lids, primarily to facilitate the installation of handles or the connection to the pot body. Glass pot lids are generally round with a central knob, which helps maintain the temperature of the contents, prevent liquid splashing, and control steam escape.

[0003] Existing glass lid drilling processes mainly employ mechanical drilling. However, contact-type mechanical drilling, due to uneven contact pressure, easily causes stress concentration in the glass, resulting in notches, cracks, and chipping at the drilled edges, severely affecting the quality of the hole. Direct contact may generate localized high pressure, creating cracks in the glass. These cracks may further propagate during processing, eventually leading to glass breakage. Furthermore, glass lids are generally held in place by clamps, and drilling is performed by the reciprocating movement of only one drilling mechanism, which can easily lead to deviations in the hole position between different glass lids, making it unsuitable for mass production. Utility Model Content

[0004] The purpose of this invention is to provide a drilling device for glass covers. By using multiple laser drilling units to pre-drill holes and then using a hole-expanding component to expand the holes and improve the surface roughness of the hole walls, the problem of glass covers breaking due to traditional devices is solved.

[0005] To address the problems of existing technologies, this utility model provides a drilling device for glass covers, comprising: a glass cover conveying assembly for conveying cut glass covers and glass waste; a waste conveyor disposed at the end of the glass cover conveying assembly for conveying glass waste; a drilling assembly for drilling holes in the glass cover and disposed on the side of the waste conveyor away from the glass cover conveying assembly; a second glass cover conveyor disposed at the front end of the second glass cover conveyor for continuously conveying glass covers; and a positioning assembly disposed at the feed end of the second glass cover conveyor for constraining the glass cover to the center of the second glass cover conveyor. The drilling assembly includes several uniformly distributed laser drilling units for drilling holes in the surface of the glass cover and several uniformly distributed hole enlarging assemblies for enlarging the holes. The laser drilling unit includes a laser head capable of left-right and back-forward movement, and the laser head also integrates several second vision detectors. The hole enlarging assembly includes an enlarging head capable of left-right and back-forward movement, and the enlarging head can also move up and down. The enlarging head can also rotate around its axis, and the bottom of the enlarging head also holds an enlarging drill bit.

[0006] Preferably, the positioning assembly includes two support blocks respectively disposed on both sides of the second glass cover conveyor, and two positioning rods are fixed between each support block by bolts, forming a "V" shaped cavity between the two positioning rods and between the support blocks to accommodate the glass cover plate.

[0007] Preferably, the positioning assembly further includes a third telescopic drive member disposed outside the second glass cover conveyor for driving the positioning rod to move, and the output end of the third telescopic drive member is connected to the support block.

[0008] Preferably, the laser drilling unit includes a first moving module arranged parallel to the conveying direction of the second glass cover conveyor, and a first housing is provided on the top of the first moving module. Inside the first housing, a second moving module for driving the laser head to move back and forth is also provided, and the laser head is installed at the bottom of the front end of the second moving module.

[0009] Preferably, the enlarging assembly further includes a third moving module arranged parallel to the conveying direction of the second glass cover conveyor, and a second housing is provided on the top of the third moving module. A fourth moving module for driving the enlarging head to move back and forth is also provided in the second housing, and the enlarging head is located at the front of the fourth moving module.

[0010] Preferably, a support plate is fixed on the punching assembly near the feed end of the second glass cover conveyor, and at least two support platforms are also provided on the support plate.

[0011] Preferably, the punching assembly is further fixed with a transfer assembly for transferring the glass cover on the support platform to the second glass cover conveyor near the support plate. The transfer assembly includes a transfer robot installed on the punching assembly. A second telescopic drive is also vertically installed on the transfer robot. The output end of the second telescopic drive is connected to a second suction cup.

[0012] Preferably, the second glass cover conveyor includes two sets of pulleys rotatably disposed at both ends of the second glass cover conveyor, and each set of pulleys consists of two pulleys. A conveyor belt is sleeved between the pulleys, and the two conveyor belts are symmetrical about the central plane of the second glass cover conveyor. A conveyor motor for driving the pulleys to rotate is also fixed to the outside of the second glass cover conveyor.

[0013] Preferably, the glass cover conveying assembly includes a first glass cover conveyor and a first moving mechanism installed on both sides of the first glass cover conveyor. The first moving mechanism is also provided with a second moving mechanism that can reciprocate along the conveying direction of the first glass cover conveyor. The second moving mechanism is also provided with a moving plate that can reciprocate in a direction perpendicular to the conveying direction of the first glass cover conveyor. At least two first telescopic drive members are vertically arranged at the bottom of the moving plate, and the output end of the first telescopic drive member is connected to a first suction cup. A first visual detection detector for detecting the position of the glass cover is also installed on the moving plate.

[0014] The advantages of this utility model compared to the prior art are: By configuring a second glass cover conveyor, which incorporates two synchronously rotating conveyor belts forming a through-groove, the glass cover is precisely positioned at the center reference position of the second glass cover conveyor through the synchronous translational movement of two positioning rods when placed on the conveyor belts. This effectively avoids hole position deviations caused by positional shifts during drilling, providing a fundamental guarantee for subsequent processing accuracy. During the conveying phase, the cyclical movement of the conveyor belts drives the glass cover smoothly to the processing area of ​​the laser drilling unit along a preset path. At this time, the second vision detector detects and feeds back the real-time position parameters of the glass cover, and the laser head emits a laser beam based on the detection data to complete the pre-processing of the first hole. Subsequently, the glass cover continues to move to the position directly below the next laser head, sequentially completing the continuous processing of subsequent holes. This multi-station collaboration achieves an efficient continuous drilling operation mode, significantly improving the processing speed. After the drilling process is completed, the glass cover continues to move, and the two reaming heads move downwards, driving the reaming drill bits to move downwards synchronously, respectively, to enlarge the already processed holes. During this process, the reaming drill bit can improve the surface roughness of the hole wall, ensuring the processing quality of the hole opening and hole wall. Compared with traditional devices, this structure avoids the risk of cracks on the glass cover surface due to local high pressure by combining non-contact laser drilling with precise mechanical reaming. It also has the dual advantages of high-speed drilling and high-precision processing, which can fully meet the needs of mass industrial production. Attached Figure Description

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-6As shown, this utility model provides a drilling device for glass covers, including: a glass cover conveying assembly 1, used for conveying the cut glass cover and glass waste; the glass cover conveying assembly 1 serves as the initial conveying mechanism of the device, mainly undertaking the task of conveying the cut glass cover and glass waste, providing material transfer support for subsequent processing and waste disposal stages, ensuring that the glass cover can enter the next processing stage in an orderly manner, and simultaneously conveying the glass waste generated during processing in a designated direction. A waste conveyor 2, located at the end of the glass cover conveying assembly 1, is used for conveying glass waste; the waste conveyor 2 is specifically used to receive and convey the glass waste conveyed by the glass cover conveying assembly 1, realizing centralized transfer and processing of waste, avoiding waste accumulation that affects the normal operation of the device, and maintaining a clean processing environment. A drilling assembly 3 is used to drill holes in the glass cover and is located on the side of the waste conveyor 2 away from the glass cover conveying assembly 1; a second glass cover conveyor 4 is located at the front end of the second glass cover conveyor 4 for continuously conveying the glass cover; a positioning assembly 6 is located at the feed end of the second glass cover conveyor 4 for constraining the glass cover to the center of the second glass cover conveyor 4; the drilling assembly 3 includes several uniformly distributed laser drilling units 31 for drilling holes in the surface of the glass cover and several uniformly distributed hole enlarging assemblies 32 for enlarging the holes. The laser drilling unit 31 includes a laser head 314 that can move left and right and forward and backward, and the laser head 314 also integrates several second vision detectors 315. The hole enlarging assembly 32 includes an enlarging head 324 that can move left and right and forward and backward, and the enlarging head 324 can also move up and down and rotate around its axis. The bottom of the enlarging head 324 also holds an enlarging drill bit 325.

[0024] During operation, the laser head 314 adjusts to a suitable position using left-right and forward-backward movement. The enlarging head 324 adjusts its position using left-right and forward-backward movement. First, the glass cover conveying assembly 1 transports the cut glass cover to the feeding end of the second glass cover conveyor 4, while simultaneously transporting the glass waste generated during processing to the waste conveyor 2, which then transfers the waste outward for processing. When the glass cover reaches the feeding end of the second glass cover conveyor 4, the positioning assembly 6 starts working, constraining the glass cover to the center position of the second glass cover conveyor 4 to ensure the stability of the glass cover's position during transport. Subsequently, the second glass cover conveyor 4 continuously transports the positioned glass cover to the processing area where the drilling assembly 3 is located. At the drilling assembly 3, the laser drilling unit 31 first performs the drilling operation on the glass cover. The integrated second vision detector 315 detects the position of the glass cover in real time and provides feedback, ensuring that the laser head 314 accurately emits laser light to drill the required hole on the surface of the glass cover. Several evenly distributed laser drilling units 31 work together to complete the drilling process of the glass cover. After drilling, the glass cover is conveyed to the reaming assembly 32. The reaming drill bit 325 moves up and down to approach the hole, while the reaming head 324 rotates around its own axis, driving the reaming drill bit 325 to enlarge the hole. Several evenly distributed reaming assemblies 32 work together to complete the reaming process, ensuring the size and quality of the hole. Through the coordinated operation of all components, the entire device achieves automated processing of the glass cover from conveying, positioning, drilling to reaming, while also promptly handling waste materials, efficiently and accurately meeting the drilling requirements of the glass cover.

[0025] The positioning assembly 6 includes two support blocks 62 respectively disposed on both sides of the second glass cover conveyor 4, and two positioning rods 63 are fixed between each support block 62 by bolts. A "V" shaped cavity is formed between the two positioning rods 63 and the support block 62 to accommodate the glass cover plate. The positioning assembly 6 also includes a third telescopic drive member 61 disposed outside the second glass cover conveyor 4 for driving the positioning rods 63 to move, and the output end of the third telescopic drive member 61 is connected to the support block 62.

[0026] When the glass cover reaches the feed end of the second glass cover conveyor 4, the positioning component 6 starts to work. The third telescopic drive component 61 drives the support block 62 and the positioning rod 63 to move, using the "V"-shaped cavity formed between the two positioning rods 63 and the support block 62 to accommodate the glass cover and constrain it to the center position of the second glass cover conveyor 4, ensuring the stability of the glass cover during the conveying process. Subsequently, the second glass cover conveyor 4 continuously conveys the positioned glass cover to the processing area where the drilling component 3 is located.

[0027] The laser drilling unit 31 includes a first moving module 311 arranged parallel to the conveying direction of the second glass cover conveyor 4, and a first housing 312 is provided on the top of the first moving module 311. Inside the first housing 312, a second moving module 313 for driving the laser head 314 to move back and forth is also provided. The laser head 314 is installed at the bottom of the front end of the second moving module 313.

[0028] With the help of a first moving module 311 parallel to the conveying direction of the second glass cover conveyor 4, the first housing 312 and its internal second moving module 313 and laser head 314 can move left and right. The second moving module 313 can drive the laser head 314 to move back and forth. Through the coordinated movement of the two, the laser head 314 is adjusted to a suitable position. The second vision detector 315 integrated inside the laser head 314 detects the position of the glass cover in real time and provides feedback to ensure that the laser head 314 accurately emits laser to drill the required hole on the surface of the glass cover. Several evenly distributed laser drilling units 31 work together to complete the drilling process of the glass cover.

[0029] The enlarging assembly 32 also includes a third moving module 321 arranged parallel to the conveying direction of the second glass cover conveyor 4, and a second housing 322 is provided on the top of the third moving module 321. A fourth moving module 323 for driving the enlarging head 324 to move back and forth is also provided in the second housing 322, and the enlarging head 324 is provided at the front of the fourth moving module 323.

[0030] The third moving module 321 of the reaming assembly 32 drives the second housing 322 and its internal fourth moving module 323 and reaming head 324 to move left and right. The fourth moving module 323 drives the reaming head 324 to move back and forth, and the two work together to adjust the reaming head 324 to a suitable position. Then, the reaming head 324 moves up and down to bring the reaming drill bit 325 closer to the hole. At the same time, the reaming head 324 rotates around its own axis, driving the reaming drill bit 325 to ream the hole. Several evenly distributed reaming assemblies 32 work together to complete the reaming process, ensuring the size and quality of the hole.

[0031] The glass cover conveying assembly 1 includes a first glass cover conveyor 11 and a first moving mechanism 12 installed on both sides of the first glass cover conveyor 11.

A first visual inspection detector 15 for detecting the position of the glass cover is also installed on the moving plate 14. A support plate 7 is fixed to the punching assembly 3 near the feed end of the second glass cover conveyor 4, and at least two support platforms 71 are also provided on the support plate 7.

[0032] First, the cut glass cover is conveyed by the first glass cover conveyor 11 of the glass cover conveying assembly 1. The first visual inspection detector 15 detects the position of the glass cover and provides feedback. The first moving mechanism 12 drives the second moving mechanism 13 to move along the conveying direction of the first glass cover conveyor 11. The second moving mechanism 13 drives the moving plate 14 to move perpendicular to the conveying direction, so that the first suction cup 17 is aligned with the glass cover. The first telescopic drive member 16 extends. After the first suction cup 17 adsorbs the glass cover, the first telescopic drive member 16 retracts. Then, through the movement of the first moving mechanism 12 and the second moving mechanism 13, the glass cover is transferred to the support platform 71 of the support plate 7 for temporary placement. At the same time, the first glass cover conveyor 11 conveys the glass waste generated during the processing to the waste conveyor 2, which then transfers the waste outward for processing.

[0033] Near the support plate 7, the punching assembly 3 is also fixed with a transfer assembly 5 for transferring the glass cover on the support platform 71 to the second glass cover conveyor 4. The transfer assembly 5 includes a transfer robot 51 installed on the punching assembly 3. A second telescopic drive 52 is also vertically installed on the transfer robot 51. The output end of the second telescopic drive 52 is also connected to a second suction cup 53.

[0034] The transfer robot 51 moves above the support platform 71, the second telescopic drive 52 extends, the second suction cup 53 adsorbs the glass cover, and then the second telescopic drive 52 retracts, and the transfer robot 51 transfers the glass cover to the feeding end of the second glass cover conveyor 4.

[0035] The second glass cover conveyor 4 includes two sets of pulleys 41 rotatably disposed at both ends of the second glass cover conveyor 4, and each set of pulleys 41 consists of two pulleys. A conveyor belt 42 is sleeved between the pulleys 41. The two conveyor belts 42 are symmetrical about the central plane of the second glass cover conveyor 4. A conveyor motor 43 for driving the pulleys 41 to rotate is also fixed to the outside of the second glass cover conveyor 4.

[0036] The second glass cover conveyor 4 is used for continuous conveying of glass covers, stably transporting the positioned glass covers to the processing area of ​​the drilling assembly 3, ensuring the continuity of the processing and improving production efficiency. The second glass cover conveyor 4 includes two sets of pulleys 41 rotatably mounted at both ends. Each set of pulleys 41 consists of two pulleys, with a conveyor belt 42 fitted between them. The two conveyor belts 42 are symmetrical about the central plane of the second glass cover conveyor 4, providing stable support for the glass covers. A conveyor motor 43 is also fixed externally to the second glass cover conveyor 4 to drive the pulleys 41 to rotate. The conveyor motor 43 drives the pulleys 41 to rotate, thereby driving the conveyor belts 42 to move cyclically, providing power for the conveying of the glass covers.
