Description

Technical Field

[0001] This invention relates to the field of flange processing technology, specifically an automatic positioning drilling device for processing carbon steel flanges. Background Technology

[0002] A flange is a mechanical part used to connect pipes, fittings, valves, and equipment inlets and outlets. Flanges are usually made of materials such as carbon steel, stainless steel, and alloy steel. Among them, carbon steel flanges have lower costs compared to flanges made of other materials, and carbon steel flanges have good mechanical strength, hardness, and plasticity. Therefore, carbon steel flanges are widely used in working environments where the requirements for corrosion resistance or high temperature resistance are not high.

[0003] Flanges are typically disc-shaped, and their edges usually require drilling for bolt connections. Flanges also typically have multiple holes to increase the strength of the connection. The number of holes on a flange is usually even to ensure symmetrical bolt distribution, which helps to balance the stress distribution during tightening and prevents deformation or uneven sealing caused by excessive force on one side.

[0004] Regarding the drilling of flanges, utility model patent CN220093820U discloses a drilling machine tool for processing flanges. This machine tool clamps and fixes flanges of different sizes and thicknesses by clamping blocks, adjusts the position of the mounting frame to adjust the drilling position, and thus realizes the drilling operation of flanges of different diameters. The worm and worm wheel work together to drive the disc to rotate, thereby accurately rotating the drilling position to the appropriate angle in sequence to realize the drilling of flanges.

[0005] The above technical solution has the following problems when drilling flanges: 1. Since there are usually multiple holes on the flange, when drilling flanges using the above technical solution, it is necessary to control the disc to rotate multiple times and drill the flange multiple times, which leads to a decrease in the drilling efficiency of the flange; 2. When drilling carbon steel flanges, long chips may be generated, and the long chips have a certain toughness, which makes them easy to get tangled on the drill bit. If the chips are not cleaned in time, the chips tangled on the drill bit will affect the quality and accuracy of the drilling. Summary of the Invention

A transmission component is mounted on the transmission ring at the position corresponding to the transmission rod. The transmission component is used to drive its corresponding transmission rod to move. A locking component is mounted on the transmission ring. The locking component can lock the corresponding transmission component according to the number of holes drilled in the flange, so that only the locked transmission component can drive its corresponding transmission rod to move.

[0007] Preferably, the clamping component includes a vertical plate that is slidably mounted on the conveying component. Multiple connecting springs connect the vertical plate and the conveying component. A U-shaped support plate is fixedly mounted on the upper end of the vertical plate.

[0010] Preferably, two clamping plates arranged on opposite sides are fixedly installed at the lower end of the transmission ring. The clamping plates are used to clamp onto the opposite sides of the vertical section of the support plate. The lower ends of the opposite sides of the two clamping plates are both set as inclined surfaces. The inclined surfaces of the clamping plates are used to cooperate with the vertical section of the support plate to make the horizontal section of the support plate and the transmission ring centered and aligned.

[0011] Preferably, square grooves are provided on the inner wall of the transmission ring and at the corresponding positions of the transmission rod. The transmission assembly includes a connecting sleeve that is slidably installed in the square groove. A locking hole is provided at the end of the connecting sleeve away from the central axis of the transmission ring. A relief rod is slidably installed at the end of the connecting sleeve close to the central axis of the transmission ring, and the relief rod is fixedly connected to its corresponding transmission rod.

[0012] Preferably, a clearance groove is provided at the position corresponding to the square groove in the transmission ring, and the lower side of the clearance groove is connected to the square groove through a connecting hole.

The locking rod is used to cooperate with the locking hole to lock the corresponding connecting sleeve.

[0013] Preferably, the locking assembly further includes multiple mating sleeves evenly arranged vertically on the outside of the transmission ring via threaded engagement. Multiple circumferentially evenly arranged mating posts are slidably installed on the outside of the transmission ring and below the mating sleeves, with the number of mating posts on the same horizontal plane increasing sequentially from top to bottom. The end of each mating post near the center of the transmission ring slides through the transmission ring and contacts the relief plate. The mating post is used to engage with the corresponding mating sleeve to drive the corresponding relief plate to move towards the center of the transmission ring.

[0014] Preferably, the cleaning assembly includes an L-shaped rod fixedly installed on the side of the square rod near the middle of the transmission ring. Two symmetrically arranged connecting rods are slidably installed on the lower end of the vertical section of the L-shaped rod near the square rod via guide springs. An arc-shaped plate is fixedly installed on the end of each connecting rod away from the L-shaped rod. Multiple arc-shaped grooves are evenly arranged vertically on opposite sides of the two arc-shaped plates. A cleaning rod with a telescopic structure is slidably installed in each arc-shaped groove via an arc-shaped spring, and the end of the cleaning rod away from the arc-shaped plate is set as a spherical structure.

[0015] Preferably, an L-shaped separation plate is fixedly installed on the lower end of the transmission rod near the middle of the transmission ring. The lower end of the vertical section of the separation plate is set as a trapezoidal structure. The separation plate is used to drive its two corresponding connecting rods to move in a direction away from each other.

[0016] The beneficial effects of this invention are as follows: 1. This invention can continuously drill flanges, and by setting an adjusting component to synchronously adjust the positions of multiple drilling components, the drilling components can drill flanges of different sizes. At the same time, by setting a locking component and a transmission component to cooperate, the locking component can lock the corresponding transmission component according to the number of holes on the flange. Thus, when the transmission ring moves downward, only the transmission component locked by the locking component can drive its corresponding drilling component to move downward to the corresponding position on the flange. Moreover, multiple drilling components corresponding to the locked transmission components are evenly arranged circumferentially, thereby drilling all the holes on the flange simultaneously according to the number and position of the holes, increasing the applicability and drilling efficiency of this invention.

[0017] 2. Each time the drilling component completes drilling into the flange and returns to its initial position, this invention cleans the chips wrapped around the drilling component by setting up a cleaning assembly. Simultaneously, this invention uses a cleaning rod with an elastic telescopic structure that fits against the drill bit. When the helical groove of the drill bit moves to the corresponding position of the cleaning rod, the telescopic end of the cleaning rod can insert into the helical groove of the drill bit. When the drill bit moves upward relative to the cleaning rod, the telescopic end of the cleaning rod can move along the helical groove of the drill bit, thereby cleaning the helical groove of the drill bit. Multiple cleaning rods are provided to achieve thorough cleaning of the drill bit, ensuring the quality and accuracy of the drilling process.

[0018] 3. When the clamping plate clamps and fixes the flange in the center, the present invention sets a clamping block to press against the upper end of the flange, thereby ensuring that the flange is arranged horizontally. At the same time, the present invention sets a clamping plate to align the horizontal section of the support plate and the transmission ring left and right in the center. When the drilling part is drilling, the two clamping plates can be clamped on the side of the vertical section of the support plate that is far away from each other, thereby fixing the support plate, increasing the stability during drilling, and further ensuring the drilling accuracy.

[0036] The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where no specific technology or conditions are specified in the embodiments, they shall be performed in accordance with the technology or conditions described in the literature in the field or in accordance with the product manual.

[0037] See Figure 1 and Figure 2 An automatic positioning drilling device for processing carbon steel flanges includes a base 1, a conveying component 2 installed at the middle of the upper end of the base 1, a plurality of clamping components 3 evenly arranged on the left and right sides installed on the conveying component 2, a drilling component 4 installed at the upper end of the base 1, a driving component 5 installed on the drilling component 4, and the clamping components 3 are used to clamp and fix the flange in the center.

[0038] It should be noted that the conveying component 2 in this invention uses a chain plate conveyor belt to drive the clamping component 3 to move intermittently to the right. The conveying component 2 includes a fixed seat, which is fixedly installed in the upper middle part of the base 1. A chain plate conveyor belt is installed on the upper end of the fixed seat, and the clamping component 3 is installed on the chain plate of the chain plate conveyor belt.

[0039] This invention enables continuous and precise drilling of flanges. Furthermore, it allows simultaneous drilling of all holes on a flange based on their number and position, thus increasing applicability and drilling efficiency. Specifically, firstly, the drilling position of the drilling component 4 is adjusted according to the position of the holes on the flange. Simultaneously, the drive component 5 and the drilling component 4 are coordinated to ensure that the drilling component 4 can simultaneously and uniformly drill all holes on the flange. Then, the flange is sequentially placed into each clamping component 3, and the clamping component 3 is controlled to centrally clamp and fix the flange. Next, the conveying component 2 is controlled to intermittently move multiple clamping components 3 and the flanges they clamp to the right to the corresponding position of the drilling component 4, aligning the drilling component 4 and the clamping components 3 vertically. Finally, the drive component 5 is controlled to move the drilling component 4 downwards to the corresponding position of the flange, and the drilling component 4 is activated to drill the flange.

[0040] After the flange drilling is completed, the drilling component 4 is first controlled to return to its initial position, and then the base 1 is controlled to drive the clamping component 3 to continue to move intermittently to the right. The flange after drilling is then manually removed from the clamping component 3 for further processing.

[0041] See Figures 1-3 The clamping component 3 includes a vertical plate 31 that is slidably mounted on the conveying component 2. Multiple connecting springs 32 connect the vertical plate 31 and the conveying component 2. A U-shaped support plate 33 is fixedly mounted on the upper end of the vertical plate 31. A synchronization component 34 is mounted on the upper end of the lower inner wall of the support plate 33. Multiple circumferentially evenly arranged arc-shaped clamping plates 35 are mounted on the synchronization component 34. The synchronization component 34 is used to drive the multiple clamping plates 35 to move synchronously.

[0042] The clamping component 3 is used to clamp and fix the flange in the center. Specifically, the flange is first placed between multiple clamping plates 35, and then the synchronization component 34 is controlled to drive the multiple clamping plates 35 to move synchronously toward each other, so that the multiple clamping plates 35 clamp and fix the flange in the center. When the chain plate conveyor belt of the control conveying component 2 moves intermittently to the right, the chain plate conveyor belt of the control conveying component 2 will eventually drive the clamped flange to move intermittently to the right through the upright plate 31 and the support plate 33. When it is necessary to remove the flange, the multiple clamping plates 35 can be moved synchronously away from each other by controlling the synchronization component 34.

[0043] See Figures 3-4The synchronization component 34 includes a circular plate 341 distributed above the support plate 33. The lower middle part of the circular plate 341 is fixedly connected to the output shaft of the No. 1 motor 342, which is fixedly installed on the support plate 33. The circular plate 341 is provided with inclined grooves 343 at the positions corresponding to the clamping plate 35. The ends of the inclined grooves 343 that are close to each other are arranged inclined to the side opposite to the rotation direction of the circular plate 341. A synchronization rod 344 is slidably installed in the inclined groove 343. The lower end of the synchronization rod 344 is slidably connected to the support plate 33 along the radial direction of the circular plate 341. The upper end of the synchronization rod 344 is fixedly connected to its corresponding clamping plate 35.

[0044] The synchronization component 34 is used to drive multiple clamping plates 35 to move synchronously. Specifically, by controlling the first motor 342 to drive the circular plate 341 to rotate, the circular plate 341 drives the synchronization rod 344 to move through the inclined groove 343. Since the synchronization rod 344 and the clamping plate 35 are slidably connected along the radial direction of the circular plate 341, the synchronization rod 344 drives its corresponding clamping plate 35 to move synchronously in the direction of moving closer to each other or further away from each other.

[0045] See Figure 5 Each of the multiple clamping plates 35 has a lifting block 351 fixedly installed on the lower end of the opposite side. The upper end of the multiple lifting blocks 351 on the opposite side is set as an inclined surface. Each of the multiple clamping plates 35 has a pressing block 353 slidably installed on the opposite side by a pressing spring 352, and the lower end of the pressing block 353 on the opposite side is set as an inclined surface.

[0046] When multiple clamping plates 35 move toward each other, the inclined surface of the lifting block 351 can lift the flange upward, so that there is a certain gap between the lower end of the flange and the support plate 33, preventing the flange from sticking to the support plate 33 and affecting the drilling of the flange. At the same time, under the action of the inclined surface of the clamping block 353 and the clamping spring 352, when the clamping plate 35 clamps and fixes the flange in the center, the clamping block 353 can always press against the upper end of the flange, thereby ensuring that the flange is arranged horizontally and further increasing the drilling accuracy of the flange.

[0047] See Figure 1 , Figure 2 , Figures 6-9 The drilling component 4 includes a U-shaped frame 41 fixedly installed in the middle of the upper end of the base 1. A synchronization plate 43 is fixedly installed in the middle of the lower end of the inner wall of the U-shaped frame 41 through a plurality of circumferentially evenly arranged connecting rods 42. A plurality of circumferentially arranged square rods 44 are slidably installed at the lower end of the synchronization plate 43, and the upper ends of the plurality of square rods 44 slide through the synchronization plate 43 and are jointly installed with an adjusting component 45 for synchronously adjusting the position of the square rods 44. A transmission rod 47 is slidably installed up and down at the lower end of the square rods 44 through a return spring 46. A drilling component 48 is installed at the lower end of the transmission rod 47. A cleaning component 49 for cleaning the drilling component 48 is installed on the side of the plurality of square rods 44 that are close to each other.

[0048] See Figure 2 , Figure 6 and Figure 7 The driving component 5 includes a transmission ring 51 distributed on the lower inner wall of the U-shaped frame 41. An active component 52 is connected between the upper end of the transmission ring 51 and the U-shaped frame 41. A transmission assembly 53 is installed in the transmission ring 51 at the position corresponding to the transmission rod 47. The transmission assembly 53 is used to drive its corresponding transmission rod 47 to move. A locking assembly 54 is installed on the transmission ring 51. The locking assembly 54 can lock the corresponding transmission assembly 53 according to the number of holes drilled in the flange, so that only the locked transmission assembly 53 can drive its corresponding transmission rod 47 to move.

[0049] It should be noted that the drilling component 48 in this invention uses existing technology to drill holes in the flange. The drilling component 48 includes a control unit and a drill bit. The drill bit is detachably installed at the lower end of the control unit. The control unit is fixedly installed at the lower end of the transmission rod 47. The control unit can drive the drill bit to rotate at high speed and drive the drilling downward, thereby enabling the drill bit to drill holes in the flange.

[0050] It should be noted that the active component 52 in this invention includes a plurality of circumferentially evenly arranged round rods fixedly installed on the upper end of the transmission ring 51. The upper ends of the round rods slide through the U-shaped frame 41 and are jointly fixedly installed with a transmission plate. An electric push rod is connected between the lower end of the transmission plate and the upper end of the U-shaped frame 41. When drilling is required on the flange, the electric push rod is controlled to drive the transmission ring 51 to move downward through the transmission plate and the round rods.

[0051] It should also be noted that the adjusting component 45 in this invention includes an adjusting plate distributed above the middle of the synchronous plate 43. An adjusting screw is connected to the middle of the adjusting plate by means of a threaded engagement, and the lower end of the adjusting screw is rotatably connected to the synchronous plate 43. The upper end of the adjusting screw is connected to the output shaft of the No. 2 motor, which is fixedly installed on the inner wall of the U-shaped frame 41. Multiple circumferentially evenly arranged diagonal rods are hinged to the outside of the adjusting plate. The installation positions of the diagonal rods correspond one-to-one with the square rods 44. The ends of the diagonal rods away from the adjusting plate are all inclined downwards and hinged to the upper end of their corresponding square rods 44. When it is necessary to adjust the position of the square rods 44 synchronously, the No. 2 motor is started, and the adjusting screw drives the adjusting plate to move up or down, so that the adjusting plate drives the multiple square rods 44 to move synchronously toward each other or synchronously toward each other through the diagonal rods.

[0052] The drilling component 4 is used to perform precise drilling on the flange. The drive component 5 is used to cooperate with the drilling component 4 so that the drilling component 4 can simultaneously drill all the holes on the flange according to the number of holes on the flange, thereby increasing the drilling efficiency. Specifically, firstly, the position of multiple drilling components 48 is synchronously adjusted by the control adjustment component 45 through the square rod 44 according to the drilling position on the flange. Then, the locking component 54 is controlled to lock the corresponding transmission component 53 according to the number of holes on the flange.

[0053] When the clamped flange moves directly below the synchronous plate 43, the control actuator 52 drives the transmission ring 51 to move downward. The transmission ring 51, through the transmission component 53 locked by the locking component 54, drives the corresponding transmission rod 47 to move downward, causing the transmission rod 47 to drive the corresponding drilling component 48 downward to the corresponding position of the flange. The other transmission rods 47 remain in their initial positions under the action of the return spring 46. Then, the drilling component 48, which has moved to the corresponding position of the flange, performs drilling on the flange. All holes on the flange are drilled simultaneously. After the drilling is completed, the control actuator 52, through the transmission ring 51 and the transmission component 53 locked by the locking component 54, finally drives the corresponding drilling component 48 upward to its initial position. At the same time, the cleaning component 49 cleans the chips wrapped around the drill bit of the drilling component 48, thus completing the drilling of one flange. When the next flange moves directly below the synchronous plate 43, the above steps are repeated to achieve continuous drilling of the flange.

[0054] See Figure 2 and Figure 6 Two clamping plates 513 arranged on opposite sides are fixedly installed at the lower end of the transmission ring 51. The clamping plates 513 are used to clamp the vertical section of the support plate 33 on the opposite side. The lower ends of the two clamping plates 513 on opposite sides are set as inclined surfaces. The inclined surfaces of the clamping plates 513 are used to cooperate with the vertical section of the support plate 33 to make the horizontal section of the support plate 33 and the transmission ring 51 centered and aligned.

[0055] When the drilling part 48 moves downward, the transmission ring 51 drives the clamping plate 513 to move downward to the corresponding position of the support plate 33, and the inclined surface of the clamping plate 513 can cooperate with the vertical section of the support plate 33, so that the horizontal section of the support plate 33 and the transmission ring 51 are aligned left and right. When the drilling part 48 moves downward to above the flange, the two clamping plates 513 can be clamped on the side of the vertical section of the support plate 33 that is far away from each other, thereby fixing the support plate 33 and increasing the stability during drilling.

[0056] See Figure 7 and Figure 11Square grooves 511 are provided on the inner wall of the transmission ring 51 and at the corresponding positions of the transmission rod 47. The transmission assembly 53 includes a connecting sleeve 531 that is slidably installed in the square groove 511. A locking hole 532 is provided at the end of the connecting sleeve 531 away from the central axis of the transmission ring 51. A relief rod 533 is slidably installed at the end of the connecting sleeve 531 close to the central axis of the transmission ring 51, and the relief rod 533 and its corresponding transmission rod 47 are fixedly connected.

[0057] See Figure 7 and Figures 11-15 Each position of the square groove 511 within the transmission ring 51 is provided with a clearance groove 512, and the lower side of the clearance groove 512 is connected to the square groove 511 through a connecting hole. The locking assembly 54 includes a clearance plate 541 slidably installed within the clearance groove 512. A clearance spring 542 is connected between the clearance plate 541 and the clearance groove 512. A locking rod 543 is fixedly installed at the lower end of the clearance plate 541 near the central axis of the transmission ring 51, and the end of the locking rod 543 away from the clearance plate 541 is located in the connecting hole. The locking rod 543 is used to cooperate with the locking hole 532 to lock the corresponding connecting sleeve 531. Component 54 also includes a plurality of mating sleeves 544 evenly arranged vertically on the outside of the transmission ring 51 by means of threaded engagement. A plurality of circumferentially evenly arranged mating posts 545 are slidably installed on the outside of the transmission ring 51 and below the mating sleeves 544, and the number of mating posts 545 on the same horizontal plane increases from top to bottom. The end of each mating post 545 near the middle of the transmission ring 51 slides through the transmission ring 51 and contacts the relief plate 541. The mating post 545 is used to engage with the corresponding mating sleeve 544 to drive the corresponding relief plate 541 to move towards the middle of the transmission ring 51.

[0058] The transmission assembly 53 is used to drive its corresponding transmission rod 47 to move downward synchronously when the transmission ring 51 moves downward. The locking assembly 54 is used to lock the transmission assembly 53 so that only the locked transmission assembly 53 can drive its corresponding transmission rod 47 to move downward. Specifically, before drilling the flange, the corresponding mating sleeve 544 is selected according to the number of holes on the flange, so that the number of mating pins 545 located below the selected mating sleeve 544 is the same as the number of holes on the flange. Then, the selected mating sleeve 544 is screwed on. Under the action of the threaded engagement between the mating sleeve 544 and the transmission ring 51, the mating sleeve 544 moves downward. When the mating sleeve 544 moves to the position corresponding to the mating pins 545 below it, the mating sleeve 544 can drive its corresponding multiple mating pins 545 to move towards the middle of the transmission ring 51. The mating pins 545 drive the locking rod 543 to move towards the middle of the transmission ring 51 through its corresponding relief plate 541 and insert it into the locking hole 532 of its corresponding connecting sleeve 531.

[0059] When the transmission ring 51 moves downward, the connecting sleeve 531 locked by the locking rod 543 can move downward synchronously, while the connecting sleeve 531 not locked by the locking rod 543 slides in the square groove 511. This causes the locked connecting sleeve 531 to finally drive its corresponding drilling part 48 downward to the corresponding position of the flange through the relief rod 533. The relief rod 533 and the connecting sleeve 531 are slidably connected, so as not to affect the position adjustment of multiple drilling parts 48. At the same time, the mating columns 545 located on the same horizontal plane are evenly arranged circumferentially, so that the multiple drilling parts 48 moving downward are also evenly arranged circumferentially, so that the multiple drilling parts 48 moving downward can perform uniform drilling operations at the same time, increasing drilling efficiency and drilling accuracy.

[0060] After all flange holes are drilled, the mating sleeve 544 is screwed back to its initial position. At the same time, the mating post 545 is able to return to its initial position under the action of its corresponding relief plate 541 and relief spring 542, so that the locking rod 543 corresponding to the mating post 545 releases the lock on the corresponding connecting sleeve 531.

[0061] See Figures 8-10 The cleaning component 49 includes an L-shaped rod 491 fixedly installed on the side of the square rod 44 near the middle of the transmission ring 51. Two symmetrically arranged connecting rods 493 are slidably installed on the lower end of the vertical section of the L-shaped rod 491 near the square rod 44 via guide springs 492. An arc-shaped plate 496 is fixedly installed on the end of each connecting rod 493 away from the L-shaped rod 491. Multiple evenly arranged arc-shaped grooves 494 are formed on opposite sides of the two arc-shaped plates 496. Telescopic springs 497 slidably install telescopic components within each arc-shaped groove 494. The cleaning rod 495 of the structure is provided, and the end of the cleaning rod 495 away from the arc plate 496 is set as a spherical structure; wherein, the arc plate 496 initially corresponds to the upper side of the drill bit of the drilling part 48, and the center line of the arc plate 496 coincides with the center line of the drilling part 48; an L-shaped separation plate 471 is fixedly installed on the lower end of the side of the transmission rod 47 near the middle of the transmission ring 51, and the lower end of the vertical section of the separation plate 471 is set as a trapezoidal structure. The separation plate 471 is used to drive its two corresponding connecting rods 493 to move in a direction away from each other.

[0062] The cleaning component 49 is used to clean the chips wrapped around the drilled part 48. Specifically, when the transmission rod 47 drives the drilled part 48 to move downward, the transmission rod 47 drives the separating plate 471 to move downward. At the same time, the trapezoidal structure of the separating plate 471 and the two connecting rods 493 cooperate to drive the two connecting rods 493 to move away from each other, so that the arc plate 496 will not affect the movement of the drilled part 48. After the drilling is completed, the transmission rod 47 drives the drilled part 48 to return to the initial position. When the transmission rod 47 drives the separating plate 471 and the two connecting rods 493 to separate, the two connecting rods 493 drive the arc plate 496 to return to the initial position under the action of the guide spring 492. This causes the arc plate 496 to drive the cleaning rod 495 to attach to the drill bit of the drilled part 48 at the end away from the arc plate 496. The transmission rod 47 then drives the drilled part 48 to continue to move upward, so that the cleaning rod 495 can push the chips off the drill bit of the drilled part 48 downward.

[0063] When the spiral groove of the drill bit 48 moves to the corresponding position of the cleaning rod 495, the telescopic end of the cleaning rod 495 can be inserted into the spiral groove of the drill bit 48. When the drill bit 48 moves upward, the telescopic end of the cleaning rod 495 can move along the spiral groove of the drill bit 48 and move within the arc groove 494 to compress the arc spring 497, thereby cleaning the spiral groove of the drill bit 48. The spherical structure of the cleaning rod 495 allows the telescopic end of the cleaning rod 495 to move out of the spiral groove of the drill bit 48 and return to the initial position under the action of the arc spring 497. At the same time, multiple cleaning rods 495 are provided, which is conducive to achieving thorough cleaning of the drill bit 48.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
