Description

Technical Field

[0001] This utility model relates to the field of drilling machines, and more particularly to a glass drilling machine. Background Technology

[0002] In the glass processing industry, it is often necessary to use a robotic arm to drive the connecting table to achieve the lifting and displacement of the drill bit, and to drive the drill bit to rotate at high speed through a servo motor to complete the drilling operation. Since the high-speed friction between the drill bit and the glass generates a lot of heat, if it is not cooled in time, it will not only lead to accelerated wear of the drill bit and shorten its service life, but may also cause cracks due to uneven heating of the glass, affecting the processing quality. Therefore, during the drilling process, coolant needs to be delivered to the drilling area to achieve cooling and lubrication.

[0003] However, the glass drilling equipment currently on the market still has the following defects in terms of coolant use and operational stability: existing equipment lacks effective coolant containment and anti-overflow structure. When delivering coolant to the drilling area, the coolant is easily splashed to the outside due to the centrifugal force of the high-speed rotation of the drill bit or the delivery pressure. This not only contaminates the work surface and the surrounding environment, increasing the amount of subsequent cleaning work, but may also splash onto the operator or into the interior of the surrounding electrical equipment, posing safety hazards and the risk of equipment damage. Existing equipment mostly uses unidirectional coolant delivery, and there is a lack of effective recycling mechanisms for the coolant after use. After drilling, the coolant remaining in the water receiving component will splash onto the glass surface or workbench when it leaves the glass, further increasing the cleaning burden; and the unrecovered coolant is directly discarded, resulting in resource waste, increasing processing costs, and failing to meet the requirements of energy-saving and environmentally friendly operations. Utility Model Content

[0004] The purpose of this utility model is to provide a glass drilling machine in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a glass drilling machine, comprising a mechanical arm that drives a connecting platform to move vertically, and a servo motor mounted on the connecting platform. A spraying mechanism is mounted on one side of the servo motor on the connecting platform, and a drilling mechanism is provided on the output shaft of the servo motor. The drilling mechanism is connected to the spraying mechanism. The drilling mechanism includes a sleeve fixedly installed at the bottom of the connecting platform and a housing fixedly connected to the outside. An installation rod is slidably installed on the inner side of the sleeve, and a drill bit is installed at the bottom end of the installation rod. A sealing slip ring is slidably installed on the inner side of the housing. The spraying mechanism includes a liquid storage tank fixedly installed on the top of the connecting platform and a water receiving sleeve slidably installed on the lower part of the housing. A water pump is installed in the liquid storage tank, and a water outlet pipe connected to the housing is installed on the output end of the water pump. The water receiving sleeve is connected to the liquid storage tank through a water suction pipe.

[0006] As a further description of the above technical solution: two sealing rings are symmetrically installed between the shell and the sleeve, the sealing slip ring slides between the two sealing rings, and several flow holes are opened through the annular array on the lowest sealing ring. Several connecting rods are installed in annular array between the sealing slip ring and the bottom end of the inner cavity of the water receiving sleeve.

[0007] As a further description of the above technical solution: several connecting rods pass through several flow holes respectively, and the inner wall diameter of the flow hole is larger than the outer wall diameter of the connecting rod. A spring is sleeved on the outside of the sleeve, and the two ends of the spring abut against the uppermost sealing ring and the sealing slip ring respectively.

[0008] As a further description of the above technical solution: a connecting plate is fixedly installed on one end of the output shaft of the servo motor that extends into the sleeve. The outer side of the connecting plate away from the axis has a number of connecting holes arranged in a ring array. The top of the mounting rod is equipped with a number of positioning rods that are adapted to the number of connecting holes in a ring array. A damping strip is glued to the inner side of the sleeve below the connecting plate.

[0009] As a further description of the above technical solution: a filter plate is installed inside the liquid storage tank, and the filter plate divides the liquid storage tank into two parts, wherein the water suction pipe and the water pump are located on both sides of the filter plate.

[0010] As a further description of the above technical solution: a rubber pad is installed at the bottom end of the water receiving sleeve, and a through hole adapted to the drill bit is opened through the axis of the bottom end of the water receiving sleeve.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: The robotic arm drives the connecting platform downwards, causing the drill bit, driven by a servo motor to rotate at high speed, to drill a hole in the glass. When the connecting platform moves downwards, the water receiving sleeve, which is slidably connected at the bottom of the housing, first comes into contact with the glass. The coolant in the storage tank is then pumped into the housing by a water pump. The coolant in the housing flows downwards into the water receiving sleeve to wet and cool the glass and the drill bit in the drilling area. The water receiving sleeve prevents coolant from splashing outwards. The enclosure design of the water receiving sleeve prevents coolant from overflowing, keeping the working environment clean and avoiding the potential impact of coolant splashing on operators or surrounding equipment. The water jacket is first attached to the glass before the coolant is delivered, which ensures that the coolant is accurately applied to the required area and avoids contamination of non-working areas. At the same time, the pre-attachment of the water jacket can assist in positioning and indirectly improve the stability of the drilling operation. After the water pump delivers the coolant from the storage tank to the housing, a negative pressure is generated in the storage tank. This pressure is then used to draw the coolant from the water jacket back into the storage tank for recycling. This reduces the amount of coolant that would spill onto the glass surface or workbench after drilling is completed and the water jacket leaves the glass, thus reducing the amount of environmental cleanup work and preventing resource waste caused by coolant.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figure 1 and Figure 2As shown, the present invention provides a glass drilling machine, including a mechanical arm 1 that drives the connecting platform 2 to move vertically, and a servo motor 3 installed on the connecting platform 2. A spraying mechanism 5 is installed on one side of the servo motor 3 on the connecting platform 2. A drilling mechanism 4 is provided on the output shaft of the servo motor 3. The drilling mechanism 4 is connected to the spraying mechanism 5.

[0016] In practical use, the robotic arm 1 drives the connecting platform 2 to bring the drilling mechanism 4 below it closer to the glass. Once the drilling mechanism 4 reaches the preset position, the servo motor 3 drives the drilling mechanism 4 to rotate at high speed to drill holes in the glass. This, in turn, drives the component drilling mechanism 4 below the connecting platform 2 to gradually approach the glass surface. At the same time, the spraying mechanism 5 precisely delivers coolant to the drilling area of ​​the component drilling mechanism 4, thereby fully immersing and efficiently cooling the glass drilling surface and the high-speed rotating drill bit. In addition, the spraying mechanism 5 can also effectively prevent the coolant in the glass drilling area from overflowing through its own structural design, and promptly recover the coolant in the area, taking into account both cooling effect and resource utilization.

[0017] Specifically, such as Figures 3-5 As shown, the drilling mechanism 4 includes a sleeve 42 fixedly installed at the bottom of the connecting platform 2 and a housing 41 fixedly connected to the outside. An installation rod 47 is slidably installed on the inner side of the sleeve 42, and a drill bit 471 is installed at the bottom of the installation rod 47. A sealing slip ring 451 is slidably installed on the inner side of the housing 41. Two sealing rings 411 are symmetrically installed between the housing 41 and the sleeve 42. The sealing slip ring 451 slides between the two sealing rings 411. Several flow holes 412 are opened through the annular array on the bottom sealing ring 411. Several connecting rods 45 are installed in an annular array between the sealing slip ring 451 and the bottom of the inner cavity of the water receiving sleeve 52. Several connecting rods 45 pass through several flow holes 412 respectively, and the inner diameter of the flow hole 412 is larger than the outer diameter of the connecting rod 45. A spring 44 is sleeved on the outside of the sleeve 42, and the two ends of the spring 44 abut against the uppermost sealing ring 411 and the sealing slip ring 451 respectively. A connecting plate 43 is fixedly installed on one end of the output shaft of the servo motor 3 that extends into the sleeve 42. A number of connecting holes 431 are opened in a ring array on the outer side of the connecting plate 43 away from the axis. A number of positioning rods 48 that are adapted to the number of connecting holes 431 are installed in a ring array at the top of the mounting rod 47. A damping strip 432 is glued to the inner side of the sleeve 42 below the connecting plate 43. Start the servo motor 3. The output shaft of the servo motor 3 drives the drill bit 471 to rotate at high speed through the mounting rod 47 to drill holes in the glass. The drill bit 471 is mounted on the lower side of the mounting rod 47 by a positioning pin, which makes it convenient to change the drill bit 471 of different sizes according to the diameter of the hole. As the robotic arm 1 drives the connecting platform 2 downwards to approach the glass, the water receiving sleeve 52 first contacts the upper surface of the glass downwards. After the water receiving sleeve 52 contacts the glass, it pushes the sealing slip ring 451 inside the housing 41 upwards through the connecting rod 45. This releases the sealing effect of the sealing slip ring 451 on the flow hole 412. In this way, after the coolant in the spray mechanism 5 is drawn into the housing 41, it can flow downwards through the flow hole 412 to wet and cool the glass drilling area and the drill bit. After the drilling is completed, when the robotic arm 1 drives the connecting platform 2 to move upward, the water receiving sleeve 52 moves away from the upper surface of the glass. At this time, the tension of the spring 44 pushes the sealing slip ring 451 to reset, preventing the coolant from continuing to flow downward through the flow hole 412.

[0018] Specifically, such as Figures 2-5 As shown, the spraying mechanism 5 includes a liquid storage tank 51 fixedly installed on the top of the connecting platform 2, and a water receiving sleeve 52 slidably installed on the lower part of the housing 41. A water pump 512 is installed inside the liquid storage tank 51. A water outlet pipe 54 connected to the housing 41 is installed on the output end of the water pump 512. The water receiving sleeve 52 and the liquid storage tank 51 are connected by a water suction pipe 53. A filter plate 511 is installed inside the liquid storage tank 51. The filter plate 511 divides the liquid storage tank 51 into two parts, with the water suction pipe 53 and the water pump 512 located on both sides of the filter plate 511. A rubber pad 521 is installed at the bottom of the water receiving sleeve 52, and a through hole 522 adapted to the drill bit 471 is opened through the shaft at the bottom of the water receiving sleeve 52. Start the water pump 512. The water pump 512 draws the coolant in the storage tank 51 into the housing 41 through the outlet pipe 54. After the water pump 512 draws the coolant in the storage tank 51 and delivers it into the housing 41, a negative pressure is generated in the storage tank 51. Then, the coolant in the water jacket 52 is recycled and drawn back into the storage tank 51 through the suction pipe 53 for reuse. After the suction pipe 53 delivers the coolant into the storage tank 51, the glass powder generated by drilling in the coolant is filtered through the filter plate 511. After the water jacket 52 is lowered and comes into contact with the glass, the rubber pad 521 at its bottom end prevents the water jacket 52 from making hard squeezing contact with the glass. At the same time, after the coolant in the housing 41 falls into the water jacket 52, the rubber pad 521 prevents the coolant in the water jacket 52 from flowing out through the through hole 522, so that the coolant can only be in the water jacket 52 to wet and cool the drilling area and the drill bit 471.

[0019] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
