Description

Technical Field

[0001] This invention relates to pearl processing equipment, specifically to a fully automatic pearl drilling machine. Background Technology

[0002] Pearls are the core organic gemstone in jewelry processing, and the drilling process is a key step in the production of pearl jewelry, directly affecting the pass rate, quality, and production efficiency of finished pearl products.

[0003] Traditional pearl drilling is mainly done manually, relying on simple clamps and handheld drilling machines. This method has many drawbacks: manual positioning is difficult, which can easily lead to problems such as eccentricity, skewness, and rough hole walls, resulting in a high rate of pearl scrap; manual labor is labor-intensive and the processing efficiency is low, which cannot meet the needs of large-scale production; the clamping force is difficult to control, which can easily damage the surface of the pearl and poses operational safety hazards; the pearl powder generated during drilling can also pollute the environment and harm the health of operators.

[0004] Subsequent semi-automatic pearl drilling equipment only simplified some operations, still requiring manual completion of processes such as feeding, positioning, and unloading, resulting in low automation; the equipment has poor clamping stability, insufficient adaptability to pearls of different specifications, inconvenient adjustment of drilling parameters, lack of precision calibration and dust collection functions, making it difficult to guarantee stable drilling quality and failing to meet the industry's demand for efficient and standardized production.

[0005] Existing pearl drilling equipment generally suffers from problems such as low automation level, poor processing accuracy, low efficiency, and insufficient environmental safety, making it difficult to meet the production requirements of large-scale, high-quality, and low-cost pearl processing industry. Therefore, the development of an automatic pearl drilling machine with high automation, accurate drilling, and stable operation has become an urgent need for industry upgrading. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a fully automatic pearl drilling machine in view of the various defects and deficiencies of the existing technology.

[0007] The specific technical solution of the present invention is as follows: a fully automatic pearl drilling machine, including a control cabinet and a workbench. The control cabinet is equipped with an electrical control system and a pneumatic control system. The workbench is located on the top of the control cabinet. Two pearl drilling mechanisms are mounted opposite each other on the workbench. Each pearl drilling mechanism includes a feeding device, a feeding device, and a set of drilling devices mounted opposite each other. A pearl fixing device is also installed between the drilling devices. The feeding device and the drilling devices are installed adjacent to each other. The feeding device is located at the rear of the feeding device and the drilling devices. A control panel is also installed on the top of the workbench. Openable glass doors are installed on all four sides of the workbench.

[0008] Furthermore, the feeding device is equipped with a feeding base fixedly installed on the top of the control cabinet. A feeding hopper is fixedly installed on the top of the feeding base, and a feeding hopper rod is provided at the bottom of the feeding hopper. The feeding hopper rod has a through hole. The feeding device is also equipped with a feeding cylinder installed inside the control cabinet. The cylinder rod of the feeding cylinder passes through the control cabinet and the feeding base and extends into the feeding hopper rod. A feeding gathering rod is installed at the front end of the cylinder rod of the feeding cylinder.

[0009] Furthermore, the feeding device is equipped with a feeding base mounted on the top of the control cabinet. The feeding base is equipped with a feeding column assembly, which is equipped with a feeding adjustment screw. The columns and the feeding adjustment screw of the feeding column assembly are equipped with feeding adjustment blocks. A feeding fixing plate is mounted on the outside of the feeding adjustment blocks. The feeding fixing plate is equipped with a feeding slide rail and an arc groove plate. A camshaft is mounted on the arc groove plate. The front end of the camshaft is connected to a guide plate (and the other end is connected to a motor). The front end of the camshaft is also equipped with a protrusion that is embedded in the groove of the arc groove plate. A feeding slider that matches the feeding slide rail is mounted on the inside of the guide plate. A feeding bracket is also mounted on the bottom of the outside of the guide plate. The feeding bracket is L-shaped and has a feeding suction pipe mounted on its bottom. The feeding suction pipe is connected to an air pump. A water baffle is also mounted on the outside of the feeding suction pipe on the feeding bracket. The water baffle prevents the pearls from being washed away by the water pressure of the cooling water pipe before they are fixed.

[0010] Furthermore, both the drilling device and the pearl fixing device are mounted on a drilling support. The drilling support is fixedly mounted on the top of the control cabinet. The top of the drilling support has a through groove, and drilling slide rails are installed on both sides of the through groove. The drilling device is equipped with a drilling propulsion motor. The connecting rod of the drilling propulsion motor is connected to a worm gear block assembly. The worm gear block of the worm gear block assembly is fixedly connected to a drilling movable seat located on the drilling support through a connecting block. The drilling movable seat has a drilling slider that matches the drilling slide rails. The top of the drilling movable seat is fixedly mounted with... There is a punching motor support, on which a punching motor is fixedly mounted. A punching needle is mounted at the front end of the punching motor. An L-shaped punching limit sensor plate is also mounted on one side of the punching moving base. Punching limit sensor switches are also mounted on both sides of the punching limit sensor plate on the punching support. When the punching needle punches forward, the punching needle stops punching and retracts when the previous punching limit sensor switch senses the punching limit sensor plate. Each time a hole is punched, the punching needle retracts to the point where the next punching limit sensor switch senses the punching limit sensor plate.

[0011] Furthermore, the pearl fixing device is equipped with a fixing base mounted on the drilling support. A fixing cylinder is mounted on the top of the fixing base, and a fixing clamp is connected to the fixing cylinder. A fixing block is mounted on the top front end of the fixing clamp. The fixing block has a fixing through hole corresponding to the drilling needle. A hollow fixing rod is mounted inside the fixing through hole. The fixing block and fixing rod can be replaced and adjusted according to different pearl sizes. A fixing groove is opened in the center of the fixing rod. The groove allows space for the pearl powder to be released during the drilling process and also allows the cooling water to carry the pearl powder away from the groove. A fixing arc groove is also provided at the front end of the fixing rod. A pushing cylinder is also mounted on the top of the fixing cylinder. A T-shaped pushing rod is mounted on the pushing cylinder and located inside the fixing rod. Fixing induction brackets are also mounted on both sides of the fixing cylinder on the drilling support. A needle tip induction switch is mounted on the fixing induction bracket above the drilling needle. When the drilling needle retracts, the needle tip induction switch detects whether the drilling needle is damaged or broken. If so, the operation stops and an alarm is issued to remind the worker to avoid damage to the needle and the production of unqualified products during processing.

[0012] Furthermore, a discharge chute is fixed below the fixed clamp by a discharge bracket. The discharge chute extends into a discharge hole slot located on the top of the control cabinet. The discharge hole slot extends into the control cabinet and a discharge extension chute extends to the outside of the control cabinet. A cooling water pipe is also installed on one side of the discharge chute, with the outlet of the cooling water pipe aligned between the two fixed clamp rods.

[0013] Furthermore, the feeding and gathering rod is located inside the feeding hopper rod. When retracted, its top is flush with the top of the feeding hopper rod. The top of the feeding and gathering rod also has a gathering arc groove. When pearls are placed in the feeding hopper, they will roll to the bottom of the feeding hopper due to inertia. At the same time, pearls will automatically fill the gathering arc groove. When the feeding and gathering rod is lifted by the feeding cylinder, the pearls in the gathering arc groove will be pushed up, and other pearls will automatically roll into the feeding hopper.

[0014] This invention, employing the above technical solutions, offers the following advantages: 1. Fully automated feeding, positioning, drilling, and unloading eliminates the need for frequent manual operation, significantly reducing labor costs. 2. Precise positioning of the pearl's center ensures uniform hole diameter and upright hole position, effectively reducing issues such as eccentricity, breakage, and rough edges, thus improving the yield rate. 3. Continuous and stable operation at a speed far exceeding manual drilling, suitable for batch processing, significantly increasing output per unit time. 4. User-friendly human-machine interface with one-button start-up reduces the risks associated with manual hand-held operations, making it simpler and safer to use. 5. Adaptable to pearls of different sizes, easily adjustable to meet diverse processing needs. Attached Figure Description

A pearl fixing device 8 is also installed between the punching devices 6. The feeding device 3 and the punching devices 6 are installed adjacent to each other. The feeding device 4 is located at the rear of the feeding device 3 and the punching devices 6. A control panel 10 is also installed on the top of the workbench 2. The workbench 2 is equipped with openable glass doors on all four sides.

[0024] Furthermore, the feeding device 3 is provided with a feeding base 31 fixedly installed on the top of the control cabinet 1. A feeding hopper 32 is fixedly installed on the top of the feeding base 31. A feeding hopper rod 33 is provided at the bottom of the feeding hopper 32. The feeding hopper rod 33 is provided with a through hole. The feeding device 3 is also provided with a feeding cylinder 34 installed inside the control cabinet 1. The cylinder rod of the feeding cylinder 34 passes through the control cabinet 1 and the feeding base 31 and extends into the feeding hopper rod 33. A feeding gathering rod 35 is installed at the front end of the cylinder rod of the feeding cylinder 34.

[0025] Furthermore, the feeding device 4 is equipped with a feeding base 41 mounted on the top of the control cabinet 1. A feeding column assembly 42 is mounted on the feeding base 41. A feeding adjusting screw 43 is mounted on the feeding column assembly 42. Feeding adjusting blocks 44 are mounted on the columns of the feeding column assembly 42 and the feeding adjusting screw 43. A feeding fixing plate 45 is mounted on the outside of the feeding adjusting block 44. The feeding fixing plate 45 is equipped with a feeding slide rail 46 and an arc-shaped groove plate 47. A camshaft 48 is mounted on the arc-shaped groove plate 47. The front end of the camshaft 48 is connected to a guide plate (4). 9. The other end is connected to the motor. The front end of the camshaft 48 is also provided with a protrusion that is embedded in the groove of the arc groove plate 47. The inner side of the guide plate 49 is equipped with a feeding slider 51 that matches the feeding slide rail 46. The bottom of the outer side of the guide plate 49 is also equipped with a feeding bracket 50. The feeding bracket 50 is L-shaped and is equipped with a feeding suction pipe 52 at its bottom. The feeding suction pipe 52 is connected to an air pump. The outer side of the feeding suction pipe 52 is also equipped with a baffle plate 53 on the feeding bracket 50. The baffle plate 53 prevents the pearl from being washed away by the water pressure of the cooling water pipe 97 before it is fixed.

[0026] Furthermore, both the drilling device 6 and the pearl fixing device 8 are mounted on the drilling support 61. The drilling support 61 is fixedly mounted on the top of the control cabinet 1. The top of the drilling support 61 is provided with a through groove, and drilling slide rails 68 are installed on both sides of the through groove. The drilling device 6 is provided with a drilling push motor 62. The connecting rod of the drilling push motor 62 is connected to the worm gear block assembly 63. The worm gear block of the worm gear block assembly 63 is fixedly connected to the drilling moving seat 64 located on the drilling support 61 through a connecting block. The drilling moving seat 64 is provided with a drilling slider that matches the drilling slide rail 68. The top of the drilling moving seat 64 is fixedly mounted with a drilling device. A motor support 65 is provided, on which a drilling motor 66 is fixedly mounted. A drilling needle 67 is mounted at the front end of the drilling motor 66. An L-shaped drilling limit sensor plate 69 is also mounted on one side of the drilling moving seat 64. Drilling limit sensor switches 70 are also mounted on both sides of the drilling limit sensor plate 69 on the drilling support 61. When the drilling needle 67 drills forward, the drilling needle 67 stops drilling and retracts when the previous drilling limit sensor switch 70 senses the drilling limit sensor plate 69. Every 10 drillings, the drilling needle 67 retracts to the point where the next drilling limit sensor switch 70 senses the drilling limit sensor plate 69.

[0027] Furthermore, the pearl fixing device 8 is equipped with a fixing base 81 mounted on the drilling support 61. A fixing cylinder 82 is mounted on the top of the fixing base 81, and a fixing clamp 83 is connected to the fixing cylinder 82. A fixing block 84 is mounted on the front end of the fixing clamp 83. The fixing block 84 has a fixing through hole 85 corresponding to the drilling needle 67. A hollow fixing rod 86 is installed inside the fixing through hole 85. The fixing block 84 and the fixing rod 86 can be replaced and adjusted according to different pearl sizes. A fixing groove 87 is opened in the center of the fixing rod 86. The groove allows space for the release of pearl powder during the drilling process and also facilitates the cooling water flow. Pearl powder is carried away from the channel. The front end of the fixed clamping rod 86 is also provided with a fixed arc groove 88. The top of the fixed cylinder 82 is also equipped with a pusher cylinder 89. The pusher cylinder 89 is equipped with a T-shaped pusher rod 90 located inside the fixed clamping rod 86. Fixed sensing brackets 95 are also installed on both sides of the fixed cylinder 82 on the drilling support 61. The fixed sensing bracket 95 is located above the drilling needle 67 and is equipped with a needle tip sensing switch 96. When the drilling needle 67 retracts, the needle tip sensing switch 96 senses whether the drilling needle 67 is damaged or broken. If so, it stops working and issues an alarm to remind the worker to avoid damage to the needle tip during processing and the production of unqualified products.

[0028] Furthermore, a discharge chute 92 is fixed below the fixed clamp 83 by a discharge bracket 91. The discharge chute 92 extends into the discharge hole slot 93 located on the top of the control cabinet 1. The discharge hole slot 93 extends into the control cabinet 1 and is provided with a discharge extension slot 94 extending to the outside of the control cabinet 1. A cooling water pipe 97 is also installed on one side of the discharge chute 92, and the outlet of the cooling water pipe 97 is aligned between the two fixed clamp rods 86.

[0029] Furthermore, the feeding and gathering rod 35 is located inside the feeding hopper rod 33. When retracted, its top is flush with the top of the feeding hopper rod 33. The top of the feeding and gathering rod 35 also has a gathering arc groove 36. When pearls are placed in the feeding hopper 32, they will roll to the bottom of the feeding hopper 32 due to inertia. At the same time, pearls will automatically fill the gathering arc groove 36. When the feeding and gathering rod 35 is lifted by the feeding cylinder 34, the pearls in the gathering arc groove 36 will be pushed up, and other pearls will automatically roll into the feeding hopper 32.

[0030] During operation, a certain number of pearls are first poured into the feeding hopper 32. The machine is started, and the feeding cylinder 34 operates, driving the feeding gathering rod 35 to move upward. A pearl will be embedded in the gathering arc groove 36. Then, the feeding device 4 operates, and the camshaft 48 drives the guide plate 49 and the feeding bracket 50 to rotate, so that the feeding suction pipe 52 is directly above the feeding gathering rod 35. The air pump connected to the feeding suction pipe 52 is started, so that the feeding suction pipe 52 sucks up the pearl in the gathering arc groove 36. Then, the camshaft 48 operates, driving the guide plate 49 and the feeding bracket 50 to rotate in the opposite direction, bringing the pearl between the two fixed clamping rods 86. Then, the fixed cylinder 82 controls the fixed clamping head 83 to move inward, driving the fixed clamping rod 86 on the fixed clamping block 84 to clamp. When the pearl is held in place, the drilling push motor 62 starts working, driving the drilling moving seat 64 to move through the worm gear block group 63. At the same time, the drilling motor 66 starts, driving the drilling needle 67 to drill holes on both sides of the pearl simultaneously. During the drilling process, the outlet of the cooling water pipe 97 sprays cooling water onto the pearl, which can cool the heat generated by drilling and prevent dust from flying. After the drilling is completed, the drilling push motor 62 controls the drilling motor 66 to reset, and then the fixing cylinder 82 controls the fixing chuck 83 to move outward, driving the fixing clamp rod 86 on the fixing clamp block 84 to release the pearl. The pearl then falls onto the discharge chute 92, rolls down the slope into the discharge hole groove 93, and then comes out from the discharge extension groove 94, falling into the pearl basket below.

[0031] To prevent the pearls from sticking to the fixed clamp 86, after the fixed clamp 86 is released, the pusher cylinder 89 operates, causing the T-shaped pusher rod 90 to push outward. The lower part of the T-shaped pusher rod 90 will pass between the two fixed clamps 86. If any pearls are stuck, they will be pushed out. Then the T-shaped pusher rod 90 will reset. The feeding pipe 52 will only send the pearls between the two fixed clamps 86 after the T-shaped pusher rod 90 has reset. This process is repeated.

[0032] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
