Description

Technical Field

[0001] This application relates to the field of magnetic material processing technology, and in particular to a dual-station fully automatic magnetizer. Background Technology

[0002] Magnetic materials are essential building blocks in industries such as electronics, automobiles, and home appliances, and their performance largely depends on the crucial magnetization process. Currently, the commonly used semi-automatic magnetization methods still require manual handling of loading, unloading, positioning, and startup operations, resulting in limited production efficiency and high labor costs. With the increasing level of industrial automation, the market demand for highly efficient and stable fully automatic magnetization equipment is becoming increasingly urgent.

[0003] There is a type of workpiece that needs to be magnetized; this workpiece is a ring-shaped metal sheet. In existing processes, workers often perform simple wiping or blowing while manually loading the workpiece. However, this cleaning method has significant shortcomings. First, the cleaning effect depends on the operator's experience, making it difficult to maintain consistent cleanliness. Second, manual operation cannot completely remove fine impurities; residues may affect the uniformity of magnetization during the magnetization process, and even cause poor contact between the workpiece and the magnetizing head, thus reducing the magnetization pass rate. Furthermore, manual cleaning prolongs the single-piece operation cycle, further restricting overall production efficiency, and may introduce quality fluctuations due to poor operational consistency.

[0004] Therefore, in the process of promoting the full automation of the magnetization process, how to achieve rapid, stable and thorough surface cleaning of workpieces before loading, reduce human interference, and ensure the reliability of the magnetization process and the consistency of product quality has become one of the key technical issues restricting the industry's automation upgrade. Summary of the Invention

[0005] To improve the magnetization efficiency of workpieces, this application provides a dual-station fully automatic magnetizer.

[0006] The dual-station fully automatic magnetizer provided in this application adopts the following technical solution: A dual-station fully automatic magnetizing machine includes a magnetizing bracket, a feeding mechanism, a discharging mechanism, and a moving mechanism for moving workpieces. The feeding mechanism has a feeding cylinder assembly for arranging workpieces and also includes an air blowing cleaning mechanism disposed in the feeding cylinder assembly. The air blowing cleaning mechanism includes a first cleaning component for cleaning the top of the workpiece and a second cleaning component for cleaning the bottom of the workpiece. The first cleaning component includes a first airbag, a first airbag telescopic frame for mounting the first airbag, an extrusion member disposed at the bottom of the moving mechanism, and a spiral side edge disposed on the feeding cylinder; The second cleaning assembly includes a second airbag, a second airbag telescopic frame for mounting the second airbag, and a transmission structure connecting the second airbag telescopic frame and the first airbag telescopic frame. When the feeding clamp moves down, the extrusion member pushes the first airbag telescopic frame, the first airbag is compressed and outputs gas, the first airbag telescopic frame drives the second airbag telescopic frame to extend through the transmission structure, and the second airbag extends and draws in gas.

[0007] By adopting the above technical solution, the fully automatic magnetizer is equipped with an air blowing cleaning mechanism. When the feeding clamp moves down, the extrusion component pushes the first airbag telescopic frame, causing the first airbag to compress and output gas to clean the top of the workpiece. At the same time, the first airbag telescopic frame drives the second airbag telescopic frame to extend through the transmission structure, allowing the second airbag to draw in gas to clean the bottom of the workpiece. This achieves cleaning of both the upper and lower parts of the workpiece, ensuring magnetization effect and product quality.

[0008] Optionally, the feeding mechanism includes a second pushing component, a feeding plate disposed on the second pushing component, multiple sets of feeding cylinders spaced apart on the feeding plate, a lifting sliding plate sleeved on the feeding cylinders, and a lifting component disposed on the magnetizing bracket.

[0009] By adopting the above technical solution, the second pushing component of the feeding mechanism can drive the feeding plate to move. Multiple sets of feeding cylinders are spaced apart on the feeding plate to store multiple workpieces to be magnetized. The lifting sliding plate sleeved on the feeding cylinder, together with the lifting component, can realize the orderly feeding of workpieces, thereby realizing the automatic feeding function and improving the production efficiency of the magnetizer.

[0010] Optionally, the feeding cylinder assembly includes two feeding cylinders arranged at intervals, and the side wall of the feeding cylinder is provided with a positioning side ridge that cooperates with the workpiece positioning. The lifting assembly includes a lifting mounting seat, a lifting screw disposed on the lifting mounting seat, a lifting motor that drives the lifting screw to rotate, and a lifting slide mounted on the lifting screw. The lifting slide includes a lifting seat that is threadedly engaged with the lifting screw, a guide rod fixed to the lifting seat, and a push plate disposed at the end of the guide rod. The lifting slide has extensions on both sides that extend beyond the loading plate and correspond to the push plate.

[0011] By adopting the above technical solution, the workpiece positioning can be achieved by arranging the feeding cylinder and the positioning side ridges on the side wall of the feeding cylinder in two intervals of the feeding cylinder assembly; the lifting screw and lifting motor of the lifting assembly are used to drive the lifting slide to move, and the extensions on both sides of the lifting sliding plate correspond to the push plate, so that the lifting sliding plate can move in a regular manner; by combining the magnetizing bracket, magnetizing mechanism, feeding mechanism, unloading mechanism and moving mechanism, the automation level of the magnetizing process can be improved, the magnetizing production efficiency can be increased and the labor cost can be reduced.

[0012] Optionally, the unloading mechanism includes an unloading conveyor belt and an unloading motor that drives the unloading conveyor belt to rotate; The moving mechanism includes a moving frame, a moving bracket slidably mounted on the moving frame, a moving motor for driving the moving bracket to move, and loading and unloading clamps disposed on opposite sides of the moving bracket.

[0013] By adopting the above technical solution, the unloading mechanism's unloading conveyor belt and unloading motor work together to automatically transport the magnetized workpiece away from the magnetizer. The moving mechanism's moving frame, moving support, moving motor, loading clamp, and unloading clamp work together to automatically move the workpiece, realize loading and unloading, reduce manual operation, and improve the production efficiency of the magnetizer.

[0014] Optionally, the feeding clamping component includes a feeding lifting cylinder and two sets of vacuum adsorption components disposed at the output end of the feeding lifting cylinder; The unloading clamping component includes a first unloading cylinder and a second unloading cylinder. The output end of the first unloading cylinder is provided with a magnetic plate for adsorbing the magnetized workpiece, and the output end of the second unloading cylinder is provided with an isolation plate, which is located above the magnetic plate.

[0015] By adopting the above technical solution, the loading and lifting cylinder of the loading clamping component drives the two sets of vacuum adsorption components to lift and lower to realize the loading of the workpiece. The first unloading cylinder of the unloading clamping component drives the magnetic plate to adsorb the magnetized workpiece, and the second unloading cylinder drives the isolation plate to move, which works in conjunction with the magnetic plate to realize the unloading of the workpiece. The whole process realizes the automated operation of workpiece loading and unloading, and improves the production efficiency of the magnetizer.

[0016] Optionally, the airbag telescopic frame includes a supporting base plate, a fixed frame body fixed to the top of the feeding cylinder, a movable frame body slidably mounted on the fixed frame body, and a first elastic element connecting the fixed frame body and the movable frame body. The top and bottom of the first airbag are respectively fixedly connected to the movable frame body and the supporting base plate. By adopting the above technical solution, the first airbag telescopic frame adopts a structure of supporting base plate, fixed frame body, movable frame body and first elastic element, so that the first airbag can be pushed by the squeezing element when the feeding clamp moves down during the magnetizer feeding process, so as to realize the first airbag compresses and outputs gas to clean the top of the workpiece. At the same time, the first airbag telescopic frame drives the second airbag telescopic frame to stretch through the transmission structure, so that the second airbag draws in gas to prepare for cleaning the bottom of the workpiece.

[0017] Optionally, the side wall of the feeding cylinder is provided with an output channel that communicates with the bottom of the first airbag and is used to deliver gas downward. The output channel has a fan-shaped cross-section, and its bottom wall has a guide conveying surface that slopes downwards away from the first airbag. A guide notch is provided at the bottom of the guide conveying surface. By adopting the above technical solution, an output channel is opened circumferentially on the side wall of the feeding cylinder, which is connected to the bottom of the first airbag and used to convey gas downward. The gas compressed and output by the first airbag can be used to clean the workpiece. The cross-section of the output channel is fan-shaped, and the bottom wall has a guide conveying surface that slopes downward away from the first airbag and a guide notch at the bottom, which can better convey the gas downward and improve the cleaning effect on the top of the workpiece.

[0018] Optionally, the second airbag is annularly sleeved on the fixed frame body. The second airbag telescopic frame includes an annular fixed frame, an annular movable frame slidably mounted on the annular fixed frame, and a second elastic element connecting the annular fixed frame and the annular movable frame. The top of the annular movable frame body is provided with a delivery channel that communicates with the top of the second airbag and is used to deliver gas upward. The transmission structure includes a first tooth surface disposed on the annular moving frame, a second tooth surface disposed on the moving frame body, and a transmission gear disposed between the first tooth surface and the second tooth surface. The transmission gear is rotatably mounted on the feeding cylinder via a gear seat.

[0019] By adopting the above technical solution, the second airbag is ring-shaped and sleeved on the fixed frame. In conjunction with the second airbag telescopic frame composed of the ring fixed frame, the ring movable frame, and the second elastic element, as well as the ring movable frame with a conveying channel, gas can be conveyed upwards. The arrangement of the first tooth surface, the second tooth surface, and the transmission gear in the transmission structure enables transmission between the first airbag telescopic frame and the second airbag telescopic frame. Thus, when the first airbag compresses and outputs gas, the second airbag can stretch and draw in gas, blowing air to clean the top and bottom of the workpiece respectively, ensuring the cleanliness of the workpiece and improving the magnetization effect.

[0020] In summary, this application includes at least one of the following beneficial technical effects: This application includes a magnetizing bracket, a magnetizing mechanism, a loading mechanism, an unloading mechanism, and a moving mechanism, which realizes the automation of the workpiece magnetizing process, reduces manual loading, unloading, positioning, and starting operations, improves production efficiency, and reduces labor costs. The air blowing cleaning mechanism utilizes the extrusion component to push the first airbag telescopic frame when the feeding clamp moves down, so that the first airbag compresses and outputs gas to clean the top of the workpiece. At the same time, the first airbag telescopic frame drives the second airbag telescopic frame to extend through the transmission structure, so that the second airbag can draw in gas to clean the bottom of the workpiece, thus achieving cleaning of the upper and lower parts of the workpiece. The output channel has a fan-shaped cross-section, and the bottom wall has a guide conveying surface that slopes downward away from the first airbag and a guide notch at the bottom, which can better convey the gas downward and improve the cleaning effect on the bottom of the workpiece.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0033] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail. Example 1:

[0034] Reference Figure 1 A dual-station fully automatic magnetizer includes a magnetizing bracket 1, a magnetizing mechanism 2 mounted on the magnetizing bracket 1, a feeding mechanism 3 located on one side of the magnetizing mechanism 2, a discharging mechanism 4 mounted on the other side of the magnetizing mechanism 2, and a moving mechanism 5 for transferring workpieces.

[0035] Reference Figure 1 and Figure 2 The magnetization mechanism 2 includes a magnetization component 21, a ring-shaped push plate 22, and a first push component 23. The magnetization component 21 is a prior art magnetization device, comprising a magnetization base 211 fixed to the magnetization bracket 1, a magnetization top seat 212 mounted above the magnetization base 211, and a magnetization lifting component 213 that drives the magnetization top seat 212 to rise and fall. The magnetization base 211 is fitted with a lower pole head that contacts the workpiece, and the magnetization top seat 212 has an upper pole head corresponding to the lower pole head. The magnetization lifting component is a lifting cylinder. When the magnetization base 211 and the magnetization top seat 212 are fully closed, the workpiece is clamped between the two pole heads, and the random magnetic domains within the workpiece align along the magnetic field direction through electromagnetic induction.

[0036] The first pushing component 23 can be a linear drive mechanism in the prior art, such as an electric linear drive mechanism or a hydrodynamic linear drive mechanism. In this embodiment, the first pushing component 23 is a motor linear drive mechanism, which includes a drive motor 231, a drive screw 232 connected to the output end of the drive motor 231, a screw nut 233 threadedly engaged with the drive screw 232, and two sets of linear slide rails 234.

[0037] The ring push plate 22 is fixed to the lead screw nut 233 so that it can move synchronously with the lead screw nut 233. The ring push plate 22 has two positioning through holes 221 for the workpiece to pass through. The inner diameter of the positioning through holes 221 is adapted to the workpiece, specifically 1-2 mm larger than the outer diameter of the workpiece.

[0038] A support guide plate 214 extending toward the first pushing assembly 23 is fixed to the top of the magnetizing base 211. The positioning through hole 221 always corresponds to the support guide plate 214, that is, before and after the annular pushing plate 22 is pushed by the first pushing assembly 23, the workpiece is always supported by the support guide plate 214. The support guide plate 214 has through holes on both sides, and the lower electrode head of the magnetizing base 211 is located in the through hole, and the top surface of the lower electrode head is flush with the top of the support guide plate 214.

[0039] Reference Figure 1 and Figure 3 The feeding mechanism 3 is used to feed workpieces one by one, and includes a second pushing component 31, a feeding plate 32, multiple feeding cylinder groups 33, a lifting sliding plate 34, and a lifting component 35.

[0040] The second pushing assembly 31 and the first pushing assembly 23 have the same structure, which will not be repeated in this application. The feeding plate 32 is fixedly installed on the lead screw nut of the second pushing assembly 31. The feeding cylinder group 33 is evenly spaced along the length direction of the second pushing assembly 31, and each feeding cylinder group 33 has two feeding cylinders. The bottom of the feeding cylinder is fixedly connected to the feeding plate 32, and its outer side wall also has a positioning side ridge 331 adapted to the workpiece. The positioning side ridge 331 and the notch of the workpiece are matched to realize the positioning of the workpiece in the feeding cylinder.

[0041] The arrangement direction of the two feeding cylinders is parallel to the arrangement direction of the two positioning through holes 221. In this embodiment, the feeding mechanism 3 has four sets of feeding cylinder groups 33. The workpiece ring can be manually fitted or automatically fed by a robot, and the annular workpiece to be magnetized is fitted onto the feeding cylinder.

[0042] The lifting sliding plate 34 and the feeding cylinder assembly 33 correspond one-to-one, and each has two sliding through holes 341 for sliding cooperation with the feeding cylinder. The annular workpieces sleeved on the feeding cylinder are all supported by the lifting sliding plate 34, and the lifting and lowering of the lifting sliding plate 34 will drive the workpieces to lift and lower synchronously.

[0043] The lifting assembly 35 is installed at the bottom of the magnetizing bracket 1 and is used to drive the lifting sliding plate 34 to rise and fall. The structural principle of the lifting assembly 35 is the same as that of the first pushing assembly 23, except that the lifting assembly 35 is arranged vertically. The output direction of the lifting assembly 35 is vertical, and it includes a lifting mounting base 351, a lifting screw 352 installed on the lifting mounting base 351, a lifting motor 353 that drives the lifting screw 352 to rotate, and a lifting slide 354 on which the lifting screw 352 is installed.

[0044] The lifting motor 353 and the lifting screw 352 are connected by gear transmission. The lifting slide 354 includes a lifting seat 3541 that is threaded into the lifting screw 352, a guide rod 3542 fixed to the lifting seat 3541, and a push plate 3543 installed on the top of the guide rod 3542. The lifting seat 3541 has four sets of guide rods 3542, which vertically pass through the magnetizing bracket 1. The push plate 3543 is installed on two adjacent sets of guide rods 3542.

[0045] The lifting sliding plate 34 has extensions at both ends that extend to both sides of the feeding plate 32. The push plate 3543 corresponds to the extensions, so that when the push plate 3543 is vertically lifted and lowered under the action of the lifting assembly 35, it can drive the lifting sliding plate 34 to slide along the axial direction of the feeding cylinder, thereby lifting the workpiece in the feeding cylinder for the moving mechanism 5 to grab and feed.

[0046] Reference Figure 5 and Figure 6 The unloading mechanism 4 is a conventional belt conveyor device, which includes an unloading conveyor belt 41 and an unloading motor 42 that drives the unloading conveyor belt 41 to rotate. The conveying direction of the unloading conveyor belt 41 is consistent with the pushing direction of the first pushing component 23.

[0047] The moving mechanism 5 includes a moving frame 51, a moving bracket 52 slidably mounted on the moving frame 51, a moving motor 53 driving the moving bracket 52 to move horizontally, and a loading clamp 54 and a unloading clamp 55 mounted on the moving bracket 52. The moving frame 51 is generally gantry-shaped and is fixed to the top of the magnetizing bracket 1 by bolts. The moving bracket 52 is generally U-shaped, and the moving frame 51 has a horizontal slide rail that slides with the moving bracket 52. The output end of the moving motor 53 is provided with a synchronous belt, and the top of the moving bracket 52 has a fixing block fixed to one side of the synchronous belt. By rotating the moving motor 53 forward and reverse, the moving bracket 52 can move horizontally back and forth on the moving frame 51.

[0048] The feeding clamping component 54 includes a feeding lifting cylinder 541 and two sets of vacuum adsorption components 542 installed at the output end of the feeding lifting cylinder 541. The two sets of vacuum adsorption components 542 include a vacuum disk 5421 fixed to the output end of the feeding lifting cylinder 541, a plurality of flexible adsorption heads 5422 circumferentially arranged at the bottom of the vacuum disk 5421, and a vacuum tube 5423 arranged at the top of the vacuum disk 5421 and communicating with the flexible adsorption heads 5422.

[0049] The unloading clamp 55 includes a first unloading cylinder 551 and a second unloading cylinder 552, with the first unloading cylinder 551 located above the second unloading cylinder 552.

[0050] A vertical plate extending vertically is fixed to the output end of the first feeding cylinder 551, and a magnetic plate 5511 for adsorbing the magnetized workpiece is fixed to the bottom of the vertical plate. The magnetic plate 5511 includes two sets of annular portions corresponding to the positioning through holes 221 and a connecting portion connecting the two annular portions. An annular magnet is embedded in the bottom of the annular portion.

[0051] The output end of the second feeding cylinder 552 is provided with an isolation plate 5521. The isolation plate 5521 has an isolation groove for arranging the magnetic plate 5511. The magnetic plate 5511 and the support guide plate 214 are isolated by the isolation plate 5521.

[0052] After the workpiece is magnetized in the magnetization mechanism 2, the ring push plate 22 pushes the workpiece to the outside of the support guide plate 214. At the same time, the first unloading cylinder 551 and the second unloading cylinder 552 are activated to move downward, so that the workpiece is attracted to the bottom of the isolation plate 5521. After being lifted and reset, the unloading clamp 55 is moved to the side of the unloading conveyor belt 41 by the moving motor 53. The first unloading cylinder 551 and the second unloading cylinder 552 are activated again to move downward, so that the workpiece and the unloading conveyor belt 41 are in contact. The first unloading cylinder 551 and the second unloading cylinder 552 are activated in sequence to move upward, so that the workpiece can be stably arranged on the unloading conveyor belt 41, reducing the influence of the magnetic plate 5511 on the workpiece.

[0053] The implementation principle of a dual-station fully automatic magnetizer according to an embodiment of this application is as follows: multiple workpieces are placed in the loading cylinder manually or with mechanical gloves. The loading cylinder moves under the action of the second pushing component 31 until it corresponds to the loading clamp 54. The lifting component 35 is activated to lift the lifting sliding plate 34 upward. The loading clamp 54 abuts against the workpiece through the flexible adsorption head 5422 and fixes the workpiece by vacuum adsorption. Under the action of the moving motor 53, the workpiece is moved above the ring pushing plate 22, the vacuum adsorption is released, and the workpiece falls onto the positioning through hole 221. The first pushing component 23 pushes the workpiece to the magnetization area. After magnetization is completed, the unloading clamp 55 moves the workpiece to the unloading conveyor belt 41. Example 2:

[0054] Reference Figure 7 and Figure 8 To improve the magnetization efficiency of the workpiece, this application also includes an air-blowing cleaning mechanism 6 disposed on the feeding mechanism 3, used to clean the top and bottom surfaces of the workpiece, so as to achieve a tight fit between the workpiece and the upper and lower electrode heads, ensuring the effective transmission of the magnetization magnetic field. The air-blowing cleaning mechanism 6 includes a first cleaning component 61 and a second cleaning component 62.

[0055] The first cleaning assembly 61 is used to clean the top of the workpiece and includes a first airbag 611, a first airbag telescopic frame 612, an extruder 613, and a spiral side rib 614. The first airbag telescopic frame 612 is installed on the top of the feeding cylinder for mounting the first airbag 611. The first airbag telescopic frame 612 includes a support base plate 6121 fixed to the inner hole of the feeding cylinder, a fixed frame body 6122 fixed to the top of the feeding cylinder, a sliding frame body 6123 slidably mounted on the fixed frame body 6122, and a first elastic member 6124 connecting the fixed frame body 6122 and the sliding frame body 6123.

[0056] The bottom and top of the first airbag 611 are fixed to the supporting base plate 6121 and the sliding frame 6123, respectively. The outer wall of the first airbag 611 also has folds extending vertically. The first elastic element 6124 is a compression spring used to drive the fixed frame 6122 and the sliding frame 6123 to tend to move away from each other.

[0057] The bottom outer wall of the first airbag 611 is circumferentially provided with four air supply pipes 6111, and the side wall of the upper cylinder is circumferentially provided with output channels 332 corresponding to the air supply pipes 6111. The output channels 332 have a fan-shaped cross-section in the horizontal direction, which can blow gas along the fan-shaped surface to the top surface of the workpiece. The first airbag 611 is provided with a first one-way valve 6112 inside the air supply pipes 6111, which controls the gas to flow only from the first airbag 611 to the output channels 332; the bottom of the first airbag 611 is provided with an input pipe connected to the gas source, and a second one-way valve 6113 is provided inside the input pipe. The second one-way valve 6113 controls the gas to flow only from the gas source to the first airbag 611.

[0058] To further improve gas conveying efficiency, a guide conveying surface 3321 is provided at the bottom of the conveying channel 6211. The guide conveying surface 3321 gradually slopes downwards away from the axis of the upper feed cylinder. A guide notch 3322 is also provided on the side of the guide conveying surface 3321 away from the axis of the upper feed cylinder, which guides the gas downwards. An arc-shaped blocking part 3323 is provided on the side of the conveying channel 6211 away from the first airbag 611 to reduce the inner diameter of the output port of the output channel 332, thereby increasing the pressure of the gas when it is output from the output channel 332.

[0059] Combination Figure 9 The spiral side rib 614 is spirally fixed to the top outer side of the upper feed cylinder along the height direction, and the bottom of the spiral side rib 614 and the top of the positioning side rib 331 are seamlessly connected. The width of the spiral side rib 614 is adapted to the notch of the workpiece. When the annular plate rotates circumferentially under the guidance of the spiral side rib 614, in this embodiment, the annular plate can rotate 90 degrees under the guidance of the spiral side rib 614, so that the output port of the output channel 332 can evenly cover the top surface of the workpiece.

[0060] The extrusion member 613 fixes the bottom of the vacuum disk 5421 and corresponds to the sliding frame 6123. The bottom height of the extrusion member 613 is lower than the height of the flexible adsorption head 5422. Therefore, before the flexible adsorption head 5422 contacts the workpiece, the extrusion member 613 first moves the sliding frame 6123 downward, thereby compressing the first air bag 611, so that gas is delivered from the output channel 332.

[0061] The second cleaning assembly 62 is used to clean the bottom of the workpiece. It includes a second airbag 621, a second airbag telescopic frame 622 for mounting the second airbag 621, and a transmission structure connecting the second airbag telescopic frame 622 and the first airbag telescopic frame 612.

[0062] The second airbag 621 has the same structure as the first airbag 611. The difference between the second airbag 621 and the first airbag 611 is that the second airbag 621 is annular, and a delivery channel 6211 is provided at the top of the second airbag 621. The second airbag telescopic frame 622 includes an annular fixed frame 6221 and an annular movable frame 6222 slidably mounted on the annular fixed frame 6221. The second airbag 621 is entirely arranged inside the annular fixed frame 6221, and its top and bottom are fixed to the annular movable frame 6222 and the annular fixed frame 6221, respectively.

[0063] The annular moving frame 6222 has an annular output port 6223 that communicates with the conveying channel 6211. The sidewall of the annular output port 6223 has an upwardly inclined guide surface 6224.

[0064] Reference Figure 7 , Figure 8 and Figure 10 The transmission structure includes a first tooth surface 6225 disposed on the annular movable frame 6222, a second tooth surface 6125 disposed on the sliding frame 6123, and a transmission gear 623 disposed between the first tooth surface 6225 and the second tooth surface 6125. The first tooth surface 6225 is disposed on the outer side wall of the sliding frame 6123 along the height direction, and the fixed frame 6122 has a relief groove 61221 corresponding to the first tooth surface 6225, so that when the sliding frame 6123 slides into the fixed frame 6122, the first tooth surface 6225 is always in contact with the outside.

[0065] The second tooth surface 6125 is disposed on the inner side wall of the annular moving frame 6222 along the height direction, and the inner side of the annular fixed frame 6221 also has a relief groove 61221 corresponding to the second tooth surface 6125.

[0066] The transmission gear 623 meshes with the first tooth surface 6225 and the second tooth surface 6125 on opposite sides, and the transmission gear 623 is rotatably mounted on the fixed frame 6122 via a gear seat. In this embodiment, two sets of transmission structures are provided on the feeding cylinder.

[0067] When the sliding frame 6123 moves downward, the annular moving frame 6222 of the second airbag telescopic frame 622 moves upward through the transmission structure, so that the gas in the second airbag 621 is replenished. When the sliding frame 6123 moves upward, the annular moving frame 6222 moves downward through the transmission structure, so that the gas in the second airbag 621 is squeezed and output from the annular output port 6223. At this time, the workpiece has been adsorbed and clamped to a certain height by the loading clamp 54, so that the gas in the second airbag 621 can be blown to the bottom of the workpiece.

[0068] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
