Description

Technical Field

[0001] This application relates to the field of transistor processing, and in particular to a burr removal device. Background Technology

[0002] Currently, after the cutting or molding process, burrs are generated on the surface of circuit board products such as transistor array boards. To ensure the flatness of the product surface, the burrs need to be removed.

[0003] In related technologies, transistor array boards typically employ one or more methods to remove burrs, including mechanical removal, chemical treatment, and heat treatment, depending on the specific characteristics of the burrs. Mechanical removal involves manually or mechanically grinding the burrs using fine sandpaper, grinding wheels, or specialized deburring tools. Chemical treatment uses specific chemical solvents or acid / alkali solutions to treat the burrs, dissolving or making them easier to remove through a chemical reaction. Heat treatment, for certain materials, softens the burrs by heating the transistor array board, allowing them to be easily removed with a scraper or other tools.

[0004] The aforementioned technologies have the following drawbacks: During the cleaning of the transistor array board, to avoid over-cleaning and damaging the board, precise control of each step in the cleaning process is required.

[0005] The requirements for processing precision are very high, so the efficiency of removing burrs from transistor array boards is low. Summary of the Invention

[0006] In order to improve the efficiency of removing burrs from products without damaging them, this application provides a burr removal device.

[0007] The burr removal device provided in this application adopts the following technical solution:

[0008] A burr removal device includes a main support, a dry ice spraying device, a feeding mechanism, and multiple waste cleaning mechanisms. The feeding mechanism includes a turntable, a central rotating shaft, and multiple rotating arms. The turntable is rotatably mounted on the main support.

[0009] The central rotating shaft is coaxially connected to the end of the turntable away from the main support;

[0010] The rotating arm is radially installed at one end of the central rotating shaft away from the turntable, and the plurality of the rotating arms are evenly spaced along the circumference of the central rotating shaft;

[0011] A limiting component is installed at one end of the rotating arm away from the central axis, and the limiting component is used to fix the product.

[0012] The dry ice spraying device is movably mounted on the main support on the side of the feeding mechanism;

[0013] Multiple waste cleaning mechanisms are correspondingly arranged with multiple rotating arms. The waste cleaning mechanisms are installed on the feeding mechanism and are used to clean the burrs that fall off the product.

[0014] By adopting the above technical solution, the product requiring burr removal is placed on a limiting component, which then secures the product. The turntable rotates, causing the central shaft and multiple rotating arms to rotate as well. The rotating arms carry the product sequentially through the processing positions of the dry ice blasting device, achieving automatic product loading. Each time a rotating arm carrying a product reaches the processing position of the dry ice blasting device, the turntable pauses its rotation. The dry ice blasting device sprays dry ice particles onto the burr edges of the product. Upon impact with the burrs, the dry ice particles rapidly sublimate, absorbing a large amount of heat, causing the burrs to freeze, become brittle, and crack rapidly. Simultaneously, the impact of the dry ice particles helps to peel off the burrs. Furthermore, because the dry ice particles rapidly sublimate upon impact, they do not damage the surface of the product being cleaned. A waste removal mechanism cleans up the detached burrs, maintaining the cleanliness of the product surface and the area around the limiting component. In this application, the dry ice blasting device, the loading mechanism, and the waste removal mechanism work together to improve the efficiency of burr removal without damaging the product.

[0015] Optionally, the limiting component includes multiple main columns, which are vertically arranged above the rotating arm. In the horizontal direction, the multiple main columns are spaced apart and are all connected to the rotating arm.

[0016] The main column has a coaxial secondary column at the end away from the rotating arm, and the diameter of the secondary column is smaller than the diameter of the main column.

[0017] By adopting the above technical solution, multiple limiting holes corresponding to multiple main columns are opened on the product, the secondary columns are inserted into the corresponding limiting holes, and the main columns support the product, thereby fixing the product.

[0018] Optionally, the main column is provided with a coaxial annular groove at the end away from the rotating arm, and the annular groove is located on the side of the auxiliary column;

[0019] The main column is equipped with a suction cup assembly, which includes an elastic ring and a ventilation pipe. The elastic ring is sleeved on the secondary column, and the inner edge of the elastic ring is sealed to the main column inside the annular groove, and the outer edge of the elastic ring is sealed to the main column outside the annular groove.

[0020] One end of the ventilation pipe is connected to the main column and communicates with the annular groove, while the other end is used to connect to a vacuum pump.

[0021] By adopting the above technical solution, when the main column supports the product, the vacuum pump draws out the air in the annular groove through the air exchange pipe, causing the middle part of the elastic ring to be recessed towards the bottom of the annular groove. This creates a negative pressure area between the recessed part of the elastic ring and the product, further securing the product. Moreover, at this time, the product is in elastic contact with the main column through the elastic ring, preventing the main column from damaging the product.

[0022] Optionally, the waste cleaning mechanism includes a rotating tube, a transmission assembly, a blowing assembly, and a dust suction assembly. The rotating tube is arranged along the length of the rotating arm and is sleeved on the corresponding rotating arm and the limiting assembly. The first end of the rotating tube is rotatably connected to the rotating arm.

[0023] The rotating pipe has a machining hole and multiple air outlet holes on its wall. The machining hole and the air outlet holes are arranged opposite to each other, and the air outlet of the air outlet hole is inclined towards the second end of the rotating pipe.

[0024] The transmission assembly is mounted on the feeding mechanism and is used to drive the rotating tube to rotate;

[0025] The blowing assembly is mounted on the feeding mechanism and connected to the air inlet of the air outlet.

[0026] The dust collection component is mounted on the feeding mechanism, and the dust collection port is rotatably connected to the second end of the rotating tube.

[0027] By adopting the above technical solution, when the dry ice blasting device is running, the rotating tube rotates so that the processing hole is above the product. At this time, the product is located inside the processing hole. The dry ice blasting device sprays dry ice particles through the processing hole toward the product to clean the rough edges. After the rough edges are cleaned, the dry ice blasting device moves away from the processing hole. The rotating tube rotates so that the air outlet is above the product. The airflow from the blowing component is sprayed through the air outlet toward the product and the limiting component area, blowing the debris toward the suction port of the dust collection component. At the same time, the dust collection component also sucks up the debris from the product and the limiting component area through the suction port, thereby cleaning the product and the limiting component area.

[0028] Optionally, an end partition is provided between the first end of the rotating tube and the rotating arm, and a bearing is connected between the first end of the rotating tube and the end partition;

[0029] The inner side of the rotating tube is provided with two side partitions that are spaced apart in the horizontal plane. The two side partitions are respectively located at both ends of the width direction of the rotating arm and are connected to the rotating arm. The end of the side partition away from the rotating arm is in dynamic sealing contact with the inner wall of the rotating tube.

[0030] By adopting the above technical solution, when the rotating tube rotates so that the air outlet is above the product, the side partition, rotating arm and end partition work together to ensure that the waste can only be discharged from the second end of the rotating tube, thereby ensuring that the waste can be blown in a directional manner towards the dust suction port of the dust collection component.

[0031] Optionally, the transmission assembly includes a gearbox, an input gear, an output gear, and a driven gear. The gearbox is located between the rotating tube and the central rotating shaft and is connected to the rotating arm.

[0032] The input gear is connected to the input shaft of the gearbox, and the output gear is connected to the output shaft of the gearbox.

[0033] The driven gear is coaxially connected to the rotating tube and meshes with the output gear;

[0034] The waste cleaning mechanism also includes a drive assembly for driving the input gear to rotate.

[0035] By adopting the above technical solution, the drive component drives the input gear to rotate, and after the gearbox changes speed and transmission, it drives the output gear to rotate, which in turn drives the driven gear to rotate, and the driven gear drives the rotating tube to rotate.

[0036] Optionally, the drive assembly includes a side bracket, a stationary support tube, and a drive gear, wherein the side bracket is mounted on the main support on the side of the turntable;

[0037] The static support tube is coaxially sleeved on the central rotating shaft and located below the rotating arm, and is connected to the side bracket;

[0038] The driving gear is coaxially connected to the stationary support tube and meshes with the input gear.

[0039] By adopting the above technical solution, the rotating tube and the turntable share a single power source. The drive gear is stationary. When the turntable drives the rotating arm to rotate, the drive gear meshes with the input gear. Simultaneously, the input gear rolls circumferentially with the drive gear as the rotating arm rotates. This, in turn, drives the rotating tube to rotate through the transmission assembly. Furthermore, the gearbox's speed regulation ensures that when the rotating arm is positioned in the processing position of the dry ice blasting device, the processing hole is precisely above the product.

[0040] Optionally, the blowing assembly includes a fan, a stationary air exchange pipe, and a transfer chamber, wherein the fan is mounted on the turntable;

[0041] The stationary ventilation pipe is coaxially disposed at the second end of the rotating pipe and is connected to the rotating arm;

[0042] The stationary ventilation pipe is provided with a coaxial annular air outlet groove at one end facing the rotating pipe. The annular air outlet groove is provided with a movable ring coaxial with the stationary ventilation pipe. The movable ring is rotatably connected to the stationary ventilation pipe and is also dynamically sealed to the stationary ventilation pipe.

[0043] The movable ring is provided with a second air outlet pipe, and the air inlet end of the second air outlet pipe is connected to the annular air outlet groove.

[0044] The outer wall of the stationary ventilation pipe is connected to the air outlet end of the fan by a first air outlet pipe located inside the stationary support pipe, and the air outlet end of the first air outlet pipe is connected to the annular air outlet groove.

[0045] The transfer chamber is located on the side of the transfer pipe and is connected to the air outlet end of the second air outlet pipe. It is also connected to the air inlet of the air outlet hole by a third air outlet pipe.

[0046] By adopting the above technical solution, the fan sequentially passes through the first air outlet pipe, the annular air outlet slot, the second air outlet pipe, the intermediate air chamber, and the third air outlet pipe before spraying airflow into the inner side of the rotating pipe. Furthermore, because the movable annulus and the stationary air exchange pipe are rotatably connected, only the second air outlet pipe, the intermediate air chamber, and the third air outlet pipe need to rotate with the rotating pipe when it rotates, simplifying the overall installation of the blowing assembly.

[0047] Optionally, the vacuuming assembly includes a vacuum cleaner and a vacuum hood, the vacuum cleaner being mounted on the turntable;

[0048] The dust hood covers the end of the stationary ventilation pipe away from the rotating pipe and is connected to the rotating arm;

[0049] A suction pipe located inside the stationary support tube is connected between the air outlet of the dust hood and the air inlet of the vacuum cleaner.

[0050] By adopting the above technical solution, when it is necessary to clean the waste inside the tube, the blower component blows the waste towards the dust hood, and the vacuum cleaner sucks the waste away through the dust hood.

[0051] Optionally, the dry ice spraying device includes a dry ice storage tank, a robotic arm, and a spray gun. The dry ice storage tank and the robotic arm are both mounted on the main support. The spray gun is connected to the robotic arm, and a flexible hose connects the spray gun and the dry ice storage tank.

[0052] By adopting the above technical solution, the robotic arm drives the spray gun to move, the spray gun draws dry ice from the dry ice storage box, and sprays dry ice particles toward the rough edges of the product.

[0053] In summary, this application includes at least one of the following beneficial technical effects:

[0054] 1. In this application, the product that needs to be deburred is placed on the limiting component. After the limiting component fixes the product, the turntable rotates, and then the central rotating shaft and multiple rotating arms rotate. The rotating arms carry the product through the processing position of the dry ice spraying device in sequence, so as to realize the automatic feeding of the product.

[0055] 2. In this application, the ice-jet device sprays dry ice particles onto the rough edges of the product. When the dry ice particles impact the rough edges of the product, they sublimate rapidly, absorbing a large amount of heat during this process. This causes the rough edges to freeze, become brittle, and crack quickly. At the same time, the impact of the dry ice particles also helps to peel off the rough edges. Moreover, since the dry ice particles sublimate rapidly when they impact the product, they do not damage the surface of the product being cleaned. Thus, in the process of removing rough edges, the product is not damaged, and the rough edges are removed efficiently.

[0056] 3. In this application, multiple limiting holes are opened on the product corresponding to multiple main columns. The secondary columns are inserted into the corresponding limiting holes, and the main columns support the product to achieve product fixation.

[0057] 4. In this application, when the main column supports the product, the vacuum pump removes the air from the annular groove through the air exchange pipe, causing the middle part of the elastic ring to be recessed towards the bottom of the annular groove. This creates a negative pressure area between the recessed part of the elastic ring and the product, further securing the product. Moreover, at this time, the product is in elastic contact with the main column through the elastic ring, preventing the main column from damaging the product.

[0058] 5. In this application, when the dry ice blasting device is running, the rotating tube rotates so that the processing hole is above the product. At this time, the product is located inside the processing hole. The dry ice blasting device sprays dry ice particles through the processing hole toward the product to clean the rough edges of the product, while the rotating tube can collect the waste.

[0059] 6. In this application, the air outlet is positioned above the product by rotating the tube. The airflow from the blowing component is sprayed towards the product and the limiting component area through the air outlet, blowing the debris towards the suction port of the dust collection component. At the same time, the dust collection component also sucks up the debris from the product and the limiting component area through the suction port, thereby cleaning the product and the limiting component area.

Detailed Implementation

[0070] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0071] This application discloses a burr removal device. (Refer to...) Figure 1 and Figure 2A burr removal device includes a main support 1, a dry ice blasting device 2, a feeding mechanism 3, and multiple waste cleaning mechanisms 4. The feeding mechanism 3 includes a turntable 31, a central rotating shaft 32, and multiple rotating arms 33. The turntable 31 is rotatably mounted on the main support 1. The central rotating shaft 32 is coaxially connected to the end of the turntable 31 away from the main support 1. The rotating arms 33 are radially mounted on the end of the central rotating shaft 32 away from the turntable 31, and the multiple rotating arms 33 are evenly spaced along the circumference of the central rotating shaft 32. A limiting component 34 is installed on the end of the rotating arm 33 away from the central rotating shaft 32, and the limiting component 34 is used to fix the product 5. The dry ice blasting device 2 is movably mounted on the main support 1 on the side of the feeding mechanism 3. The dry ice blasting device 2 includes a dry ice storage tank 21, a robotic arm 22, and a spray gun 23. Both the dry ice storage tank 21 and the robotic arm 22 are mounted on the main support 1. The spray gun 23 is connected to the robotic arm 22, and a flexible hose 24 connects the spray gun 23 to the dry ice storage tank 21. The robotic arm 22 drives the spray gun 23 to move, and the spray gun 23 draws in dry ice from the dry ice storage tank 21 and sprays dry ice particles towards the rough edges of the product 5. Multiple waste cleaning mechanisms 4 are correspondingly arranged with multiple rotating arms 33. The waste cleaning mechanisms 4 are mounted on the feeding mechanism 3 and are used to clean the rough edges that have fallen off the product 5.

[0072] Reference Figure 1 and Figure 2 In this embodiment, the product 5, whose burrs need to be removed, is placed on the limiting component 34, which fixes the product 5 in place. The turntable 31 rotates, causing the central shaft 32 and multiple rotating arms 33 to rotate as well. The rotating arms 33 carry the product 5 sequentially through the processing position of the dry ice blasting device 2, achieving automatic feeding of the product 5. Each time the rotating arm 33 carries the product 5 to the processing position of the ice blasting device, the turntable 31 pauses its rotation, and the dry ice blasting device 2 sprays dry ice particles onto the burr area of ​​the product 5. When the dry ice particles impact the burr of the product 5, they rapidly sublimate, absorbing a large amount of heat during this process, causing the burr to freeze, become brittle, and crack rapidly. Simultaneously, the impact of the dry ice particles helps to peel off the burrs. Furthermore, because the dry ice particles rapidly sublimate upon impact with the product 5, they do not damage the surface of the product 5 being cleaned. The waste cleaning mechanism 4 cleans the detached burrs from the product 5, maintaining the cleanliness of the product 5 surface and the area of ​​the limiting component 34. In this application, the dry ice spraying device 2, the feeding mechanism 3, and the waste cleaning mechanism 4 work together to improve the efficiency of removing burrs from the product 5 without damaging the product 5.

[0073] Reference Figure 2 , Figure 3 and Figure 4The limiting component 34 includes multiple main columns 341, which are vertically positioned above the rotating arm 33. Horizontally, the main columns 341 are spaced apart and all are connected to the rotating arm 33. A coaxial secondary column 342 is provided at the end of each main column 341 away from the rotating arm 33, and the diameter of the secondary column 342 is smaller than the diameter of the main column 341.

[0074] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment of the application, multiple limiting holes 501 corresponding to multiple main columns 341 are opened on the product 5, and the secondary columns 342 are inserted into the corresponding limiting holes 501. The main columns 341 support the product 5 to achieve the fixation of the product 5.

[0075] Reference Figure 2 , Figure 3 and Figure 4 The main column 341 has a coaxial annular groove 34101 at its end away from the rotating arm 33, located on the side of the auxiliary column 342. A suction cup assembly 35 is mounted on the main column 341, comprising an elastic ring 351 and a ventilation pipe 352. The elastic ring 351 is fitted onto the auxiliary column 342, with its inner edge sealingly connected to the inner side of the main column 341 within the annular groove 34101, and its outer edge sealingly connected to the outer side of the main column 341 outside the annular groove 34101. One end of the ventilation pipe 352 is connected to the main column 341 and communicates with the annular groove 34101; the other end is used to connect to a vacuum pump. The vacuum pump is mounted on the top of the central rotating shaft 32 or on the rotating arm 33.

[0076] Reference Figure 2 , Figure 3 and Figure 4 In this embodiment, when the main column 341 supports the product 5, the vacuum pump removes the air from the annular groove 34101 through the air exchange pipe 352, causing the middle part of the elastic ring 351 to be recessed towards the bottom of the annular groove 34101, thereby forming a negative pressure area between the recessed part of the elastic ring 351 and the product 5, thereby further fixing the product 5. Moreover, at this time, the product 5 is in elastic contact with the main column 341 through the elastic ring 351, preventing the main column 341 from damaging the product 5.

[0077] Reference Figure 5 , Figure 6 and Figure 7The waste cleaning mechanism 4 includes a rotating pipe 41, a transmission assembly 42, a blowing assembly 43, and a dust collection assembly 44. The rotating pipe 41 is arranged along the length of the rotating arm 33 and is sleeved on the corresponding rotating arm 33 and the limiting assembly 34. The first end of the rotating pipe 41 is rotatably connected to the rotating arm 33. The pipe wall of the rotating pipe 41 is provided with a machining hole 4101 and multiple air outlets 4102. The machining hole 4101 and the air outlets 4102 are arranged opposite to each other, and the air outlets of the air outlets 4102 are inclined towards the second end of the rotating pipe 41. The transmission assembly 42 is mounted on the feeding mechanism 3 and is used to drive the rotating pipe 41 to rotate. The blowing assembly 43 is mounted on the feeding mechanism 3 and is connected to the air inlet of the air outlet 4102.

[0078] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment, when the dry ice blasting device 2 is running, the rotating tube 41 rotates so that the processing hole 4101 is above the product 5. At this time, the product 5 is located inside the processing hole 4101. The dry ice blasting device 2 sprays dry ice particles through the processing hole 4101 toward the product 5 to clean the burrs on the product 5. After the burrs are cleaned, the dry ice blasting device 2 moves away from the processing hole 4101. The rotating tube 41 rotates so that the air outlet 4102 is above the product 5. The airflow from the blowing assembly 43 is sprayed through the air outlet 4102 toward the product 5 and the area of ​​the limiting assembly 34, blowing the debris toward the suction port of the dust collection assembly 44. The dust collection assembly 44 also sucks up the debris from the product 5 and the area of ​​the limiting assembly 34 through the suction port, thereby cleaning the product 5 and the area of ​​the limiting assembly 34.

[0079] Reference Figure 5 , Figure 6 and Figure 7 An end partition 411 is provided between the first end of the rotating tube 41 and the rotating arm 33, and a bearing 412 is connected between the first end of the rotating tube 41 and the end partition 411. Two side partitions 413 are provided on the inner side of the rotating tube 41 at intervals in the horizontal plane. The two side partitions 413 are respectively provided at both ends of the rotating arm 33 in the width direction and are both connected to the rotating arm 33. The end of the side partition 413 away from the rotating arm 33 is in dynamic sealing contact with the inner wall of the rotating tube 41.

[0080] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment of the application, when the rotating tube 41 rotates so that the air outlet 4102 is above the product 5, the side partition 413, the rotating arm 33 and the end partition 411 cooperate to ensure that the waste can only be discharged from the second end of the rotating tube 41, thereby ensuring that the waste can be blown in a direction towards the dust suction port of the dust suction assembly 44.

[0081] Reference Figure 5 , Figure 6 and Figure 7 The transmission assembly 42 includes a gearbox 421, an input gear 422, an output gear 423, and a driven gear 424. The gearbox 421 is located between the rotating tube 41 and the central rotating shaft 32, and is connected to the rotating arm 33. The input gear 422 is connected to the input shaft of the gearbox 421, and the output gear 423 is connected to the output shaft of the gearbox 421. The driven gear 424 is coaxially connected to the rotating tube 41 and meshes with the output gear 423. The waste cleaning mechanism 4 also includes a drive assembly 420, which drives the input gear 422 to rotate.

[0082] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment of the application, the drive assembly 420 drives the input gear 422 to rotate. After the gearbox 421 changes speed and drives the output gear 423 to rotate, the output gear 423 drives the driven gear 424 to rotate, and the driven gear 424 drives the rotating tube 41 to rotate.

[0083] Reference Figure 5 , Figure 6 and Figure 7 The drive assembly 420 includes a side bracket 4201, a stationary support tube 4202, and a drive gear 4203. The side bracket 4201 is mounted on the main support 1 on the side of the turntable 31. The stationary support tube 4202 is coaxially sleeved on the central rotating shaft 32 and located below the rotating arm 33, and is connected to the side bracket 4201, keeping the drive gear 4203 stationary. The drive gear 4203 is coaxially connected to the stationary support tube 4202 and meshes with the input gear 422. When the turntable 31 drives the rotating arm 33 to rotate, because the drive gear 4203 meshes with the input gear 422, the input gear 422 can roll in the circumferential direction of the drive gear 4203 while rotating with the rotating arm 33. Thus, through the transmission assembly 42, the rotating tube 41 can be driven to rotate.

[0084] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment, the number of rotating arms 33 can be set according to actual needs, but the rotating arms 33 must be equidistant from each other, and the included angle between each two adjacent rotating arms 33 must be equal. The included angle between each two adjacent rotating arms 33 is defined as A degrees. Under the speed transmission of the gearbox 421, for every A degrees that the rotating arm 33 rotates, the rotating tube 41 needs to rotate 180 degrees. And when a rotating arm 33 is just stopped at the processing position of the dry ice spraying device 2, the processing hole 4101 is just above the product 5.

[0085] Reference Figure 5 , Figure 6 and Figure 7 The blower assembly 43 includes a fan 431, a stationary ventilation pipe 433, and a transfer chamber 436. The fan 431 is mounted on the turntable 31. The stationary ventilation pipe 433 is coaxially located at the second end of the transfer pipe 41 and connected to the rotating arm 33. The end of the stationary ventilation pipe 433 facing the transfer pipe 41 has a coaxial annular air outlet groove 43301. A movable ring 434, coaxial with the stationary ventilation pipe 433, is located within the annular air outlet groove 43301. The movable ring 434 is rotatably connected to the stationary ventilation pipe 433 and also dynamically sealed to it. A second air outlet pipe 435 is located on the movable ring 434, and the air inlet end of the second air outlet pipe 435 communicates with the annular air outlet groove 43301. A first air outlet pipe 432 located inside the stationary support pipe 4202 is connected between the outer wall of the stationary ventilation pipe 433 and the air outlet end of the fan 431. The air outlet end of the first air outlet pipe 432 is connected to the annular air outlet groove 43301. When the turntable 31 rotates, the first air outlet pipe 432 can output airflow to the annular air outlet groove 43301 without causing motion interference with the stationary support pipe 4202. The intermediate transfer chamber 436 is located on the side of the transfer pipe 41 and is connected to the air outlet end of the second air outlet pipe 435. A third air outlet pipe 437 is also connected between the third air outlet pipe 436 and the air inlet of the air outlet hole 4102.

[0086] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment, the blower 431 sequentially passes through the first air outlet pipe 432, the annular air outlet groove 43301, the second air outlet pipe 435, the intermediate air chamber 436, and the third air outlet pipe 437 before spraying airflow into the inner side of the rotating pipe 41. Furthermore, since the movable ring 434 is rotatably connected to the stationary ventilation pipe 433, when the rotating pipe 41 rotates, only the second air outlet pipe 435, the intermediate air chamber 436, and the third air outlet pipe 437 need to rotate with the rotating pipe 41, simplifying the overall installation of the blowing assembly 43.

[0087] Reference Figure 5 , Figure 6 and Figure 7 The vacuuming assembly 44 includes a vacuum cleaner 441 and a vacuum hood 443. The vacuum cleaner 441 is mounted on the turntable 31. The vacuum hood 443 covers the end of the stationary air exchange pipe 433 away from the rotating pipe 41 and is connected to the rotating arm 33. A suction pipe 442 located inside the stationary support pipe 4202 connects the air outlet end of the vacuum hood 443 and the air inlet end of the vacuum cleaner 441, so that when the turntable 31 rotates, the vacuum cleaner 441 can both suck up waste from the vacuum hood 443 through the suction pipe 442 and avoid motion interference with the stationary support pipe 4202.

[0088] Reference Figure 5 , Figure 6 and Figure 7 In this embodiment of the application, when it is necessary to clean the waste inside the tube 41, the blower assembly 43 blows the waste towards the dust collection hood 443, and the vacuum cleaner 441 sucks away the waste through the dust collection hood 443.

[0089] The implementation principle of the burr removal device in this application embodiment is as follows:

[0090] Multiple limiting holes 501 corresponding to multiple main columns 341 are made on the product 5. The auxiliary columns 342 are inserted into the corresponding limiting holes 501. The main columns 341 support the product 5 to fix the product 5. Then, when the main columns 341 support the product 5, the vacuum pump draws away the air in the annular groove 34101 through the air exchange pipe 352, causing the middle part of the elastic ring 351 to be recessed towards the bottom of the annular groove 34101. This creates a negative pressure area between the recessed part of the elastic ring 351 and the product 5, further fixing the product 5.

[0091] The number of rotating arms 33 can be set according to actual needs, but the rotating arms 33 must be equidistant, and the included angle between any two adjacent rotating arms 33 must be equal. The included angle between any two adjacent rotating arms 33 is defined as A degrees.

[0092] Under the transmission of the gearbox 421, for every A degrees rotated by the rotating arm 33, the rotating tube 41 needs to rotate 180 degrees. When one rotating arm 33 is exactly at the processing position of the dry ice spraying device 2, the processing hole 4101 is directly above the product 5. At this time, the robotic arm 22 drives the spray gun 23 to move. The spray gun 23 draws dry ice from the dry ice storage tank 21 and sprays dry ice particles toward the rough edges of the product 5. When the dry ice particles hit the rough edges of the product 5, they sublimate rapidly. During this process, a large amount of heat is absorbed, causing the rough edges to freeze rapidly, become brittle, and crack. At the same time, the impact of the dry ice particles also helps to peel off the rough edges. After the rough edges are cleaned, the spray gun 23 moves away from the rotating tube 41.

[0093] The rotating arm 33 rotates by A degrees and pauses for a moment. Through the coordinated operation of the transmission component 42 and the drive component 420, the drive tube 41 rotates 180 degrees. The airflow ejected by the blowing component 43 is sprayed through the air outlet 4102 towards the product 5 and the area of ​​the limiting component 34, blowing the debris towards the suction port of the dust collection component 44. At the same time, the dust collection component 44 also sucks up the debris from the product 5 and the area of ​​the limiting component 34 through the suction port, thereby cleaning the product 5 and the area of ​​the limiting component 34.

[0094] Finally, every time the rotating arm 33 rotates by A degrees, it pauses for a period of time at the processing position of the dry ice spraying device 2, and repeats the above steps to achieve automatic removal of burrs from product 5.
