Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hardware polishing, in particular to a copper powder cleaning tool for automatic polishing equipment. BACKGROUND

[0002] The mechanical hand automatic polishing technology is an automatic surface treatment scheme relying on high-precision motion control of industrial manipulators, and matching flexible polishing tools (such as abrasive belts and polishing wheels) and force control systems. It can polish the surface of metal and non-metal workpieces by presetting paths and process parameters, and can accurately control the polishing force and trajectory, and solve the problems of poor consistency, low efficiency and poor working environment of manual polishing. When the visual detection module is integrated, defect recognition and adaptive polishing can be realized, and it is widely used in the field of hardware parts, and can greatly improve the product surface quality and production intelligent level.

[0003] Many products of the bathroom cast faucet need this polishing method, and now this process has been gradually introduced into automatic polishing manipulators to replace manual polishing. The automatic polishing is generally set in a separate isolated workshop, and the product and the manipulator polish in the workshop, and then the product is pushed out after polishing, and the copper powder is cleaned and packaged by manual operation.

[0004] The existing automatic polishing product has some problems after polishing. After the product is finished and conveyed out, a large amount of copper powder is attached to the outside and the inner cavity of the product. After processing, the personnel still need to use the air gun to blow and clean the metal powder, and the cleaning efficiency is low. After the air gun blows off the copper powder, it will be scattered everywhere, resulting in a poor working environment and metal powder dispersed in the workshop. This cleaning method will cause waste, and the scattered copper powder will contain a large amount of impurities and cannot be recycled. The high-pressure air gun will blow the copper powder to a larger range, and even the copper powder will be blown by the high-pressure air gun to the conductive area of the equipment, causing the electronic equipment to short circuit and damage.

[0005] Therefore, the present application designs a copper powder cleaning tool for automatic polishing equipment to solve the above problems. SUMMARY

[0006] The purpose of this invention is to provide a copper powder cleaning fixture for an automatic polishing equipment. This device adds an extra independent process to the workpiece without removing it. After polishing, the cleaning operation is performed directly within the original isolated polishing space. The entire process is integrated into the polishing equipment, which not only does not affect the polishing operation but also prevents the blown copper powder from spilling outside the equipment, effectively preventing copper powder from spreading in the workshop and avoiding environmental pollution. It also eliminates the need for manual cleaning of each workpiece individually. This device not only provides a polishing fixture for the workpiece, allowing multiple workpieces to be arranged neatly, but also directly blows copper powder from inside and outside the workpiece, with complete airflow coverage and good cleaning effect.

[0007] This invention is implemented as follows: a copper powder cleaning fixture for an automatic polishing device, comprising: Air knife, air storage block, base plate, blow-off support block and wind deflector; The air knife is a flat block structure. A sweeping port is vertically opened on the front side of the air knife, and an air inlet pipe is provided on the rear side of the air knife. The sweeping port is sealed to an external high-pressure air source through the air inlet pipe. The base plate is a flat plate; A vertical support plate is also vertically fixed to the rear edge of the top of the base plate, and a support plate is horizontally mounted on the top of the support plate; A translation groove is formed on the pallet along the left and right direction; the air knife is horizontally slidable in the translation groove of the pallet along the left and right direction. The wind deflector is a long flat plate. Multiple air control cylinders are horizontally fixed on the inner side of the support plate. The wind deflector is horizontally arranged at the extension end of the air control cylinder along the front-back direction. Each extension end of the air control cylinder is provided with a wind deflector. A ventilation hole is also opened on the wind deflector, and the ventilation hole penetrates the wind deflector vertically. The air storage block is a long, block-shaped structure. The air storage block is fixed to the front edge of the base plate in the left-right direction. A hollow diversion groove is opened inside the air storage block. The diversion groove opens at the top of the air storage block. An inflation pipe is also connected to the outside of the air storage block. The diversion groove and the inflation pipe are sealed and connected. The inflation pipe is connected to an external air source. The purge block is a long, block-shaped structure. The purge block is horizontally locked to the top of the air storage block. Multiple throttle holes are horizontally opened in the inner cavity of the purge block. The throttle holes are long, square holes that penetrate the front and rear sides of the purge block horizontally in the front-back direction. The multiple throttle holes are arranged in a straight line with uniform spacing in the left-right direction. Each of the throttle holes also has a vertically formed diversion hole, each of the diversion holes vertically penetrating the upper and lower sides of the purge block, and the diversion holes are connected to the upper and lower sides of the purge block through the throttle holes. Each of the air diversion holes on the purge block is connected to the inner cavity of the diversion groove. Multiple positioning seats are also installed on the top of the purge block. Each positioning seat is arranged in a straight line along the left and right direction. A docking plug is provided on the top of the positioning seat. The docking plug can be pulled out and is tightly plugged into the bottom hole of the workpiece. A cleaning hole is opened vertically downward on the top of the docking plug. The cleaning hole penetrates vertically through the bottom of the positioning seat. Each of the cleaning holes is sealed and connected to the upper port of a diversion vent, and the diversion vent coincides with the vertical axis of the cleaning hole; A wind baffle is horizontally inserted into each of the throttle holes, and the wind baffle is horizontally slidable in the throttle hole along the front-to-back direction; When the air control cylinder retracts, the throttle hole and the diversion hole of the baffle plate are not connected. When the air control cylinder extends, the air throttling hole of the baffle plate and the air diversion hole overlap and connect vertically.

[0008] Furthermore, the pallet and the base plate are parallel to each other; The tray is parallel to the top plane of both the gas storage block and the top plane of the purging tray.

[0009] Furthermore, the contact surfaces of the purge block and the gas storage block are sealed and glued together.

[0010] Furthermore, each of the positioning seats is bolted to the top of the blow-off block. The positioning seat is an integral stainless steel structure. The mating plug is a rubber plug. The mating plug is interference-fitted with the inner hole of the workpiece. The cleaning hole is open at the top of the mating plug.

[0011] Furthermore, the wind deflector and the throttle hole are clearance-fitted, and the clearance is within 0.2mm; A limiting block is also fixed to the rear side of the wind deflector. The limiting block is a square block. The front end of the limiting block is in contact with the rear side of the blow-off support block, and the limiting block is in contact with and seals the rear port of the throttle hole. The rear side of the limiting block is locked to the air control cylinder by threads.

[0012] Furthermore, the height range of the air inlet is greater than the height of the workpiece, and the width of the air inlet in the left and right directions does not exceed 5mm.

[0013] Furthermore, a translation cylinder is provided on the right side of the air knife, and the air knife is driven to slide left and right by the translation cylinder.

[0014] The beneficial effects of the present invention are: 1. The present invention adds an air knife, which can slide along the left and right direction of the pallet, and the air sweeping port of the air knife is vertically set facing the front side. By sliding the air knife left and right, the air sweeping port blows air to sweep the workpieces on the top of the positioning seat one by one, thereby cleaning the copper powder on the outside of the workpieces. The cleaning effect is good, and the air pressure of the air knife is large, and the cleaning effect is far better than that of the air gun, and the entire surface is swept. 2. The positioning seat of this device is bolted to the blowing support block, making it easy to replace and adapt to workpieces of different sizes. The workpiece is positioned by inserting a mating plug into the inner hole, which effectively ensures that the workpiece is installed stably on the positioning seat. This device can be used as a polishing fixture for workpieces and can also be used for blowing away copper powder. Moreover, the whole process is carried out in the isolation space of the polishing equipment, which prevents copper powder from spilling outside the equipment, effectively avoiding copper powder loss and protecting the workshop environment from the impact of copper powder blown by the air gun. 3. The throttle hole, ventilation hole, and baffle plate of this device work together. During the polishing process, the throttle hole and ventilation hole are aligned, and the flow channel is continuously filled with air. This prevents copper powder from entering the inner hole of the workpiece during processing. After cleaning, the baffle plate is offset from the workpiece in the front-back direction, and the workpiece is away from the support plate. The throttle hole and ventilation hole are misaligned, and the baffle plate isolates the flow channel and cleaning hole, preventing the airflow from blowing upward. This effectively prevents personnel from being affected by the airflow when removing the workpiece and forms a protective effect. As long as the workpiece is removed outward, regardless of whether the air valve is closed, the baffle plate can directly and physically prevent the airflow from blowing out, effectively preventing personnel from being swept by the airflow and the blown copper powder. This is more automated and safer. Attached Figure Description

Detailed Implementation

[0018] Please see Figures 1 to 9 As shown, the present invention provides a copper powder cleaning fixture for an automatic polishing equipment. To better understand the above technical solution, the following will describe the above technical solution in detail with reference to the accompanying drawings and specific embodiments.

[0019] In a specific embodiment of the technical solution of the present invention: Includes air knife 1, air storage block 2, base plate 23, blowing support block 3 and wind baffle 4; The air knife 1 has a flat, block-shaped structure. The front side of the air knife 1 is a vertical plane, and a vertically opened air inlet 12 is provided on the front side of the air knife 1. An air inlet pipe 11 is provided on the rear side of the air knife 1. The air inlet 12 is sealed to an external high-pressure air source through the air inlet pipe 11. The height range of the air inlet 12 is greater than the height of the workpiece, and the workpiece is within the height coverage range of the air inlet 12. The width of the air inlet 12 in the left and right directions does not exceed 5mm, so that the air inlet 12 can effectively clean the workpiece and ensure that the entire workpiece can be swept and covered by the airflow in the air inlet 12, achieving the purpose of complete cleaning.

[0020] Base plate 23 is a flat plate; The rear edge of the top of the base plate 23 is also vertically fixed with a support plate 24, and a support plate 14 is horizontally mounted on the top of the support plate 24. The support plate 14 is parallel to the base plate 23. The support plate 14 is parallel to the top of the air storage block 2 and the top plane of the purging block 3, so that the whole has a consistent flatness, which facilitates the pushing of the cylinder and also makes the cylinder movement have a higher reference plane consistency.

[0021] A translation groove 15 is formed on the pallet 14 along the left and right directions. The air knife 1 is horizontally slidable in the translation groove 15 of the pallet 14 along the left and right directions. The translation groove 15 is an oblong hole. There is a slider at the bottom of the air knife 1. The slider is locked to the bottom of the air knife 1 from the bottom to the top of the translation groove 15. The air knife 1 slides left and right in the translation groove 15 by the slider, and cannot move back and forth, but can only slide in the left and right directions. A translation cylinder 13 is set on the right side of the air knife 1. The air knife 1 is driven to slide left and right by the translation cylinder 13. Both the translation cylinder 13 and the air control cylinder 41 are controlled by the polishing equipment. The device is controlled by a PLC controller. After polishing, the copper powder is cleaned by blowing air. Simply open the air valves of the air inlet pipe 11 and the air filling pipe 21 to fill the air knife 1 and the diversion groove 22 with air. The air knife 1 blows air on the entire surface of the workpiece. It not only blows air along the surface of the workpiece, but also blows air along the outer wall of the back of the workpiece to blow off the copper powder. The reverse air through the isolation plate also blows off the copper powder on the back. The workpiece is close to the isolation plate, which makes it easy to control the removal of the workpiece and can also effectively use the reverse air to blow off the copper powder.

[0022] The wind deflector 4 is a long flat plate. Multiple air control cylinders 41 are horizontally fixed on the inner side of the support plate 24. The wind deflector 4 is horizontally set at the extension end of the air control cylinder 41 along the front-back direction. Each extension end of the air control cylinder 41, which is also the inner end, is equipped with a wind deflector 4. A ventilation hole 42 is also opened on the wind deflector 4, and the ventilation hole 42 penetrates the wind deflector 4 vertically. The air storage block 2 is a long, block-shaped structure. The air storage block 2 is fixed to the front edge of the base plate 23 in the left and right direction. A hollow diversion groove 22 is opened inside the air storage block 2. The diversion groove 22 is open at the top of the air storage block 2. An inflation pipe 21 is also connected to the outside of the air storage block 2. The diversion groove 22 and the inflation pipe 21 are sealed and connected. The inflation pipe 21 is connected to an external air source. The purge block 3 is a long, block-shaped structure. The purge block 3 is horizontally locked to the top of the air storage block 2. The contact surfaces of the purge block 3 and the air storage block 2 are sealed and glued together to ensure airtightness, prevent airflow from overflowing, and ensure that the air pressure in the cleaning hole 35 is not affected.

[0023] Multiple throttle holes 31 are horizontally opened in the inner cavity of the purge block 3. The throttle holes 31 are long rectangular holes. The throttle holes 31 penetrate the front and rear sides of the purge block 3 horizontally in the front-back direction. The multiple throttle holes 31 are arranged in a straight line with uniform intervals in the left-right direction. Each throttle hole 31 also has a vertically opened diversion hole 32. Each diversion hole 32 vertically penetrates the upper and lower sides of the blow-purge block 3, and the diversion hole 32 is connected to the upper and lower sides of the blow-purge block 3 through the throttle hole 31. Each diversion air hole 32 on the purge support block 3 is connected to the inner cavity of the diversion groove 22. Multiple positioning seats 33 are also installed on the top of the purge support block 3. Each positioning seat 33 is arranged in a straight line along the left and right direction. A docking plug 34 is provided on the top of the positioning seat 33. The docking plug 34 can be pulled out and plugged into the bottom hole of the workpiece. The workpiece is a cylindrical structure with open top and bottom ends. The surface of the workpiece needs to be polished. Each positioning seat 33 is locked in the locking hole 36 on the top of the purge support block 3 by bolts. The locking hole 36 is a screw hole used to install the positioning seat 33. There is one at the front and one at the back to ensure that the positioning seat 33 is installed stably and to facilitate the disassembly and replacement of the positioning seat 33.

[0024] The positioning seat 33 is an integral stainless steel structure, and the mating plug 34 is a rubber plug. The mating plug 34 and the inner hole of the workpiece are interference fit. The cleaning hole 35 is open at the top of the mating plug 34, so that this device can be adapted to different workpieces. Only the positioning seat 33 needs to be replaced. Moreover, the design of the mating plug 34 can hold the workpiece stably without damaging it. At the same time, this device can also be used as a tool for polishing workpieces, making it more convenient and flexible to use.

[0025] A cleaning hole 35 is vertically downward at the top of the docking plug 34, and the cleaning hole 35 vertically penetrates the bottom of the positioning seat 33; Each cleaning hole 35 is sealed and connected to the upper port of a diversion vent 32, and the diversion vent 32 coincides with the vertical axis of the cleaning hole 35. A baffle plate 4 is horizontally inserted into each throttle hole 31. The baffle plate 4 slides horizontally in the throttle hole 31 in the front-to-back direction. The baffle plate 4 and the throttle hole 31 are in clearance fit, and the clearance is within 0.2mm. A limiting block 43 is also fixed to the rear side of the wind deflector 4. The limiting block 43 is a square block. The front end of the limiting block 43 is in contact with the rear side of the blow-off support block 3. The limiting block 43 is in contact with and blocks the rear port of the throttle hole 31. When the wind deflector 4 is pushed forward, the limiting block 43 closes the rear port of the throttle hole 31. The airflow can only blow upward, and a small amount will overflow forward. This effectively prevents copper powder from blowing backward directly onto the air control cylinder 41 and prevents copper powder from adhering to the drive component. In particular, it can prevent copper powder fragments from adhering to the air control cylinder 41. The rear side of the limit block 43 is locked to the air control cylinder 41 by threads. The air control cylinder 41 drives the baffle plate 4 to extend and retract back and forth, thereby controlling whether the airflow in the diversion air hole 32 is blown out from the cleaning hole 35. This ensures that the baffle plate 4 can block the airflow when personnel take out the workpiece, regardless of whether the air valve is closed, thus protecting the personnel's safe operation.

[0026] When the air control cylinder 41 retracts, the air throttle hole 31 of the baffle plate 4 is not connected to the air diversion hole 32. When the air control cylinder 41 extends, the air throttle hole 31 of the baffle plate 4 and the air diversion hole 32 overlap and connect vertically.

[0027] It should be noted that the current copper powder blowing process is separate from the polishing process. The main reason is that during polishing, copper powder adheres to both the inside and outside of the workpiece, especially the outside, while the inside actually has less copper powder. Installing an air jet inside the polishing equipment can actually clean the outside of the workpiece, but the blowing range is narrow. This means that after processing and blowing, it is still necessary to manually blow the inside and outside surfaces of the workpiece one by one. Since manual blowing is always required, there is no need to add a process inside the equipment. This is also the main reason why automated blowing and cleaning cannot be carried out. Another important drawback is that once the grease or other impurities on the hands or gloves of the personnel come into contact with the workpiece surface, the adhesion between the copper powder and the workpiece increases greatly, making it very difficult to blow off. On the other hand, the copper powder on a freshly polished workpiece can be easily removed with a gentle blow.

[0028] 1. Throughout the polishing and cleaning process, this device does not require personnel to touch the workpiece by hand, making the copper powder blowing operation simpler and smoother. Copper powder can be detached without vigorous blowing, which also reduces the air pressure requirement. At the same time, gently blowing the copper powder can prevent the copper powder from being blown away again. Copper powder is actually very heavy. Once it is gently blown away from the workpiece, it will fall naturally. In contrast, manual blowing with a high-pressure air gun will blow away and scatter the copper powder with excessive air pressure. 2. During the processing, the cleaning hole 35 of this device continuously blows air outward, effectively preventing copper powder from falling into the workpiece, greatly reducing the cleaning requirements of the inner hole of the workpiece, and ensuring a high degree of cleanliness inside the workpiece. 3. The entire purging process takes place within the isolated space of the polishing equipment, requiring no additional large structures or additional factory space. It can also quickly clean up copper powder, prevent copper powder from spilling inside the factory, and protect the surrounding environment.

[0029] The tooling of the present invention is installed inside the isolation box of the polishing equipment. During the polishing process, the workpieces need to be vertically inserted into the docking plugs 34 one by one. After the installation is stable, the isolation chamber door of the equipment is closed.

[0030] When the control air cylinder 41 retracts, the ventilation hole 42 is aligned with the upper cleaning hole 35 and the lower diversion air hole 32, making the cleaning hole 35 and the diversion air hole 32 connected. The diversion groove 22 blows the airflow in the air filling pipe 21 into each diversion air hole 32, and the diversion air hole 32 supplies air to each cleaning hole 35, forming positive pressure.

[0031] At this point, the workpiece has been retracted to the workstation and the polishing operation begins. During the polishing process, air can be supplied to the diversion tank 22 to reduce the chance of copper powder entering the workpiece. Alternatively, air supply can be omitted, and the copper powder can be cleaned together when it is blown away at the end. Adjustments can be made according to the actual production situation of the workpiece.

[0032] After polishing is complete, open the air inlet pipe 11 and the air filling pipe 21; The airflow in the diversion groove 22 blows out the copper powder from the inner hole of each workpiece through the diversion air hole 32, the ventilation hole 42 and the cleaning hole 35, thus completing the internal cleaning operation of the workpiece.

[0033] Meanwhile, the air vent 12 blows out a vertical airflow, and the air knife 1 moves back and forth on the support plate 14 to remove copper powder from the outside of the workpiece, so that the entire workpiece is cleaned inside and out.

[0034] By shutting off the airflow from the inlet pipe 11 and the inflation pipe 21, the workpiece can be removed.

[0035] Then the air control cylinder 41 will extend forward, and the baffle plate 4 will slide forward in the throttle hole 31. The baffle plate 4, the ventilation hole 42, the cleaning hole 35, and the diversion air hole 32 are staggered. The baffle plate 4 blocks the airflow of the diversion air hole 32 to prevent the airflow from blowing out. The workpiece is then removed to complete the polishing and cleaning work.

[0036] The front side of this device refers to the side where the workpiece is installed, which is also the side where the polishing equipment is operated by the personnel. The rear side refers to the side of the support plate 24. The left and right directions refer to the directions in which the translation cylinder 13 extends and slides.
