[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figures 1-2 As shown, a semi-automatic assembly device for air pump accessories includes a transmission mechanism 1 and a bearing mechanism 2 with several sets arranged along the transmission direction of the transmission mechanism 1 for driving the spring tube 10 to complete the processing work.

[0049] Along the transmission direction of the bearing mechanism 2, there are sequentially arranged a spring tube 10 unloading station, a first fastener 11 mounting station, a second fastener 12 mounting station, a tightening station, and a discharge station;

[0050] The spring tube 10 is provided with a feeding mechanism 4 at the unloading station, a first mounting component 5 is provided at the mounting station of the first fastener 11, a second mounting component 6 is provided at the mounting station of the second fastener 12, a tightening component 7 is provided at the tightening station, and a discharge component 8 is provided at the discharge station.

[0051] The bearing mechanism 2 includes several sets of support mechanisms 3 arranged along the transmission direction of the transmission mechanism 1 for driving the spring tube 10 to complete the processing work, and an adjustment mechanism 9 located at the top of the bearing mechanism 2 for fixing the spring tube 10 to the first fastener 11 and the second fastener 12 respectively.

[0052] In this embodiment, by setting up a spring tube 10 unloading station, a first fastener 11 mounting station, a second fastener 12 mounting station, a tightening station, and a discharge station in conjunction with the bearing mechanism 2, the close cooperation between each station enables the assembly of the air pump accessories. The functional structures are reasonably set in accordance with the process sequence, the functional areas are clearly divided, and the close cooperation between the processes improves the assembly accuracy of the first fastener 11 and the second fastener 12, thereby ensuring product quality and improving production efficiency.

[0053] It should be noted that the transmission components can be sprocket and chain unit a, which is driven by a motor, and sprocket and chain unit b, which is driven synchronously with sprocket and chain unit a. The bearing mechanism 2 is provided in several sets, and only the bearing mechanism 2 at the corresponding work station is shown in the figure.

[0054] In detail, in work, firstly, the spring wire tube 10 is cut in the spring wire tube 10 blanking station, and the cut spring wire tube 10 falls on the bearing mechanism 2 under the action of its own gravity, then the transmission assembly is started, the bearing mechanism 2 is moved by the transmission assembly, in the process, the expansion assembly 33 operates, the spring wire tube 10 is expanded to ensure its stability, at the same time, the spring wire tube 10 is driven to rotate and fixed at one end by the adjusting mechanism 9, then reaches the first fastener 11 loading station, the first fastener 11 is sleeved on the outer wall of the spring wire tube 10 under the action of the first loading assembly 5, then is conveyed to the second fastener 12 loading station, the second fastener 12 is inserted at one end of the spring wire tube 10 under the action of the second loading assembly 6, then the spring wire tube 10 passes through the tightening station and completes the screw connection between the first fastener 11 and the second fastener 12 under the action of the bearing mechanism 2 and the cooperation of the tightening assembly 94 and the tightening assembly 7, finally, the spring wire tube 10 completing the installation work is taken out by the discharging assembly 8 in the discharging station, and the state of each part is restored to complete the processing work.

[0055] Further, as shown in Figure 3 、 Figure 11 and Figure 16 , the support mechanism 3 comprises a bearing table 32 connected with an auxiliary plate 31 at the top and an expansion assembly 33 located at the top of the bearing table 32, the expansion assembly 33 comprises a circular table 331 rotatingly penetrating the bottom of the bearing table 32, a circular plate 332 coaxially rotatingly arranged above the circular table 331, and a plurality of groups of arc-shaped plates on the circular table 331 slidingly arranged in the arc-shaped grooves 335 of the circular plate 332 through the L-shaped slide rods 334; the bottom outer wall of the circular table 331 is connected with a first gear ring 336, the first gear ring 336 is in meshing transmission with the driving rack 337 arranged on the external rack 13; the circular plate 332 is synchronously driven by a first gear 338, and the first gear 338 completes the tensioning work of the spring wire tube 10 under the driving of the two groups of first racks 339 arranged above and below the external rack 13.

[0056] In the embodiment, the spring wire tube 10 can be effectively expanded by the expansion assembly 33, so that it can stably lean against the outer wall of the expansion assembly 33 in the subsequent processing process, the fixing of the spring wire tube 10, the part installation are facilitated, and the position of the spring wire tube 10 can be further fixed when falling under the action of the auxiliary plate 31, so that the end of the spring wire tube 10 is prevented from moving in a large range and affecting the subsequent fixing work of the end.

[0057] In detail, after the spring wire tube 10 falls from the spring wire tube 10 blanking station, the auxiliary plate 31 cooperates with the arc-shaped plate to preliminarily lock the position of the spring wire tube 10, preventing the end thereof from moving in a large range, then in the moving process of the bearing mechanism 2, the first gear 338 drives the round plate 332 to rotate synchronously under the drive of the first rack 339, the round plate 332 pushes the L-shaped slide rod 334 away through the arc-shaped slot 335 when rotating, and then drives the arc-shaped plate to tension the spring wire tube 10, and then the first tooth ring 336 meshes with the drive rack 337 to drive the circular table 331 to rotate, the circular table 331 drives the spring wire tube 10 to rotate together with the arc-shaped plate, and cooperates with the adjusting mechanism 9 to fix one end of the spring wire tube 10.

[0058] It should be noted that when the first gear 338 drives the round plate 332 to rotate synchronously under the drive of the first rack 339, the signal device receives a signal and drives the elastic pad to increase the force required for the circular table 331 to rotate, preventing the first gear 338 from driving the circular table 331 to rotate, thereby facilitating the first rack 339 arranged below to restore the expansion assembly 33 and release the tension on the spring wire tube 10, facilitating discharging; the first gear 338 is provided with a damper to prevent it from rotating without external driving.

[0059] Further, as shown in Figure 3 and Figures 12-15 , the adjusting mechanism 9 includes a rotating frame 91, a fastening assembly 92 symmetrically arranged on both sides of the rotating frame 91 and used for fixing the position of the spring wire tube 10, an adjusting assembly 93 located on the inner wall of the rotating frame 91 and used for adjusting the tightening degree of the fastening assembly 92, and a screwing assembly 94 located on one side of the rotating frame 91 and used for connecting the first fastener 11 and the second fastener 12.

[0060] In the embodiment, the adjusting mechanism 9 provided with the fastening assembly 92, the adjusting assembly 93 and the screwing assembly 94 cooperates with the feeding mechanism 4 to work, facilitating the installation work of the first fastener 11 and the second fastener 12 to be successfully completed, and ensuring the quality in the production process of the product under the action of the adjusting mechanism 9, effectively preventing the floating of the connection tightness degree that may occur in manual operation.

[0061] In detail, in the driving process of the transmission mechanism 1, the rotating frame 91 rotates by a certain angle, and fixes one end of the spring wire tube 10 brought by the bearing mechanism 2 through the fastening assembly 92, and the adjusting assembly 93 can adjust the clamping degree of the fastening assembly 92 in the processing process, facilitating the installation work to be implemented, and the screwing work of the first fastener 11 and the second fastener 12 is completed under the action of the screwing assembly 94.

[0062] Further, as shown in Figure 12As shown, the fastening assembly 92 includes two U-shaped clamping plates 921 slidingly penetrating on both sides of the rotating frame 91 and being obliquely arranged on one side, an L-shaped block 922 connected on one side of the U-shaped clamping plate 921, a tension spring 923 connected between the L-shaped block 922 and the rotating frame 91, a first arc-shaped thin plate 925 connected to the inner wall of the U-shaped clamping plate 921 through a first spring 924; the bottom of the U-shaped clamping plate 921 is connected with a vertical rod 926, and the top of the rotating frame 91 is connected with a first guide plate 927 and a second guide plate 928 which are both arc-shaped arranged on one side and the second guide plate 928 is connected with the vertical rod 926 on the same side; the rotating frame 91 is synchronously driven by a second gear 929, and the second gear 929 is driven by two groups of second racks 9210 arranged on the outer rack 13 to complete the rotating work of the rotating frame 91.

[0063] In this embodiment, by arranging the fastening assembly 92, the end of the spring wire tube 10 can be well fixed during the processing process, instead of manual holding, and the problem that the spring wire tube 10 itself has a certain bending degree and is inconvenient to install the first fastener 11 is well solved by the guiding effect of the first arc-shaped thin plate 925, and the use is convenient.

[0064] In detail, when the spring wire tube 10 rotates under the driving of the expanding assembly 33, with the movement of the bearing mechanism 2, the second gear 929 completes the rotating work of the rotating frame 91 under the driving of the second rack 9210, so that one end of the rotating frame 91 is attached to the arc-shaped plate, and under the leading of the first guide plate 927 and the second guide plate 928 which are both arc-shaped arranged on one side, one end of the spring wire tube 10 enters between the two first arc-shaped thin plates 925 along the gap between the first guide plate 927 and the second guide plate 928, and continues to move along the first arc-shaped thin plate 925, and stops after entering between the two U-shaped clamping plates 921, thereby completing the locking of the end of the spring wire tube 10 and facilitating the subsequent installation work.

[0065] It should be noted that at this time, the state of the fastening assembly 92 is in a fixed position under the action of the adjusting assembly 93, and the space between the two first arc-shaped thin plates 925 can accommodate the spring wire tube 10 to freely enter and exit, so that it can be driven by the expanding assembly 33, and the pressure on the spring wire tube 10 can be changed under the action of the adjusting assembly, thereby facilitating the installation of the second fastener 12; the second gear 929 is provided with a damper to prevent it from rotating without external driving.

[0066] Further, as shown in FIG. 6, the adjusting assembly 93 includes a first adjusting plate 931 connected to the U-shaped clamping plate 921, a second adjusting plate 932 connected to the L-shaped block 922, and a third adjusting plate 933 connected to the vertical rod 926. Figure 13As shown, the adjustment assembly 93 includes a first slider 932 connected to the mounting grooves 931 on both sides of the rotating frame 91, a second spring 933 connected to the bottom of the first slider 932, an L-shaped rod 934 connected to the mounting groove 931 with its other end sliding in the groove 935 opened in the first slider 932, and a limiting rod 936 connected to the top of the first slider 932 with its sliding in the limiting groove 937 opened at the bottom of the U-shaped clamp 921. A triangular block 938 is connected to one side of the first slider 932. The triangular block 938 completes the adjustment of the contraction degree of the fastening assembly 92 under the action of the trigger block 939 at the bottom of the U-shaped clamp 921.

[0067] In this embodiment, by setting the adjustment component 93, the shrinkage degree of the fixing component can be appropriately changed during the processing, which facilitates the installation of the first fastener 11 and the second fastener 12.

[0068] In detail, in the initial state, the limiting rod 936 at the top of the first slider 932 is located on one side within the limiting groove 937 at the bottom of the U-shaped clamp 921, fixing the position of the U-shaped clamp 921. This prevents the tension spring 923 between the L-shaped block 922 and the rotating frame 91 from retracting, thereby limiting the gap between the fastening components 92 and facilitating the insertion of the spring tube 10. Adjustments are then made at the subsequent installation and unloading stations of the first fastener 11 to facilitate processing. The specific adjustment process is as follows: when the U-shaped clamp 921 moves to the boundary, its… The trigger block 939 at the bottom and the triangular block 938 connected to one side of the first slider 932 press against each other, causing the triangular block 938 to drive the first slider 932 to move downward. At this time, the L-shaped rod 934 slides to the top in the groove 935 opened in the first slider 932, and stops at the upper notch of the groove 935 after the trigger block 939 is removed, thereby moving the limiting rod 936 out of the limiting groove 937 and canceling the limitation on the U-shaped clamp 921, so that the tension spring 923 can continue to contract and increase the compression on the end of the spring tube 10, which is convenient for subsequent processing.

[0069] Furthermore, such as Figure 8 and Figures 14-15 As shown, the tightening assembly 94 includes a support frame 942 connected to one side of the rotating frame 91 via a base plate 941, an arc-shaped clamping plate 943 connected to the top of the support frame 942, a stop block 945 connected to one side of the arc-shaped clamping plate 943 via a third spring 944, and a clamping member 947 connected to one side of the arc-shaped clamping plate 943 via a second slider 946. An elastic rope 948 is connected to the bottom of the second slider 946.

[0070] The clamping piece 947 comprises a sleeve rod 9471 connected to one side of the second sliding block 946, an inner rod 9473 provided in the sleeve rod 9471 and connected with a double-sided rack 9472, two groups of half gears 9475 for driving two groups of clamping hands 9474 to rotate respectively and engaging with the double-sided rack 9472, a fourth spring 9476 connected to one end of the inner rod 9473; the inner rod 9473 and one side of the sleeve rod 9471 are penetrated by the same control clamping hand 9474 fixing and releasing plug rod 9477, and one side of the sleeve rod 9471 is connected with a push rod 9478.

[0071] The tightening assembly 7 comprises a wave track 71 connected to the rack, and the push rod 9478 is driven up and down under the guidance of the wave track 71.

[0072] In this embodiment, by setting the screwing assembly 94 used in cooperation with the tightening assembly 7, the screwing connection between the first fastener 11 and the second fastener 12 is more convenient to perform, and at the same time, the precision of screwing can also be improved by replacing manual operation with mechanical operation, deviation can be prevented, and production quality can be improved.

[0073] In detail, when the screwing assembly 94 passes through the second fastener 12 upper mounting station, two groups of clamping hands 9474 are fixed on both sides of the first fastener 11 respectively, then in the moving process of the carrying mechanism 2, the push rod 9478 contacts with the wave track 71 and starts to move upward, at the same time, the push rod 9478 drives the sleeve rod 9471 to move in the arc-shaped clamping plate 943, thereby driving two groups of clamping hands 9474 to rotate the first fastener 11, when the push rod 9478 reaches the top of the wave track 71, one end of the plug rod 9477 contacts and extrudes one end of the arc-shaped clamping plate 943 extending out, so that the plug rod 9477 moves out from the inside of the inner rod 9473, canceling the limiting of the inner rod 9473, then due to the elastic rope 948 being stretched after moving with the second sliding block 946, the sleeve rod 9471 is driven to return to the initial position under the action of the elastic force, in the process, due to the cancellation of the brake of the inner rod 9473, when the clamping hand 9474 rotates back to the initial position, the half gear 9475 is driven to rotate due to extrusion, so that the two clamping hands 9474 open to cancel the clamping of the first fastener 11, and after the clamping hand 9474 rotates a certain angle, the inner rod 9473 is driven to move under the action of the fourth spring 9476, the inner rod 9473 drives the double-sided rack 9472 to move, and then drives the half gear 9475 engaging with it to rotate, at this time, the clamping hand 9474 recombines with the two faces of the hexagonal bolt on the first fastener 11, at the same time, the plug rod 9477 contacts with the blocking block 945 after moving with the sleeve rod 9471, and the plug rod 9477 and the inner rod 9473 are recombined and limited under the action of the third spring 944, then the next wave action is completed, and the screwing work of the first fastener 11 and the second fastener 12 is completed through the reciprocating movement.

[0074] It should be noted that the frictional force of the first fastener 11 and the second fastener 12 screwed together is greater than the frictional force generated by the third spring 944 on the outer wall of the first fastener 11 after the clamping hand 9474 cancels the limiting, so that the clamping piece 947 holds the first fastener 11 and the second fastener 12 screwed together upwards, and when it is restored, it will not drive the first fastener 11 to rotate again, and at the same time, a gasket is arranged on the inner wall of the clamping hand 9474, thereby increasing the friction and assisting in fixing; The bottom of the support frame 942 is provided with a damper to prevent it from moving without external driving.

[0075] Further, as shown in Figures 6-7 The first upper assembly 5 includes a first storage box 52 connected with a placement table 51 and used for spacing to provide the first fastener 11, a blocking rod 54 connected with two second arc-shaped thin plates 53, a first extrusion plate 55 connected at the bottom of the blocking rod 54 and used for extruding the vertical rod 926 to make it open;

[0076] The second upper assembly 6 includes a second storage box 61 for spacing to provide the second fastener 12, a first connecting rod 63 connected with a first T-shaped rod 62, a connecting piece box 64 connected at one end of the first T-shaped rod 62 and used for placing the second fastener 12, and a second extrusion plate 65 connected at one side of the connecting piece box 64.

[0077] In this embodiment, by arranging the first upper assembly 5, the first fastener 11 is conveniently sleeved on the outer wall of the spring wire tube 10, and during the sleeving process, the first extrusion plate 55 opens the vertical rod 926 to both sides while the adjusting assembly is driven to change the control state of the fastening assembly 92, so that it can enhance the extrusion of the end of the spring wire tube 10, facilitating the subsequent installation of the second fastener 12; At the same time, the second upper assembly 6 can perform the installation work of the second fastener 12 after the first fastener 11 is installed, and by pushing, one end of the second fastener 12 is inserted into one end of the spring wire tube 10.

[0078] In detail, when the bearing mechanism 2 drives the spring wire tube 10 to move to the first fastener 11 loading station, the blocking rod 54 and the second arc-shaped sheet 53 are pushed by the driving cylinder 86, so that the second arc-shaped sheet 53 is inserted into the inside of the parts a and b in the first fastener 11 in turn, then one end of the part a is inserted into the inside of the part b under the pushing of the blocking rod 54 to complete the assembly of the first fastener 11, and then moves to one side of the fastening assembly 92 together, then the two second arc-shaped sheets 53 first fix the end of the spring hose, then the first extrusion plate 55 opens the vertical rod 926 to the two sides and opens the fastening assembly 92 at the same time, so as to facilitate the first fastener 11 to pass through, and after the conveying is completed, the second arc-shaped sheet 53 is pulled out, so that the first fastener 11 is sleeved on the outer wall of the spring wire tube 10, and the fastening assembly 92 fixes the end of the spring wire tube 10 again, and the blocking rod 54 blocks the outlet of the first fastener 11 on the first storage box 52 in the process, and when the installation is completed and returned, the new part of the first fastener 11 falls on the placement table 51 again; then the bearing mechanism 2 continues to transmit the spring wire tube 10 to the second fastener 12 loading station, at this time, the first connecting rod 63 and the first T-shaped rod 62 are moved and drive the connector box 64 to move with the second fastener 12 under the driving of the driving cylinder 86, when one end of the second fastener 12 is completely inserted into the inside of the spring wire tube 10, the outer wall of the second fastener 12 extrudes one side of the U-shaped clamping plate 921, so that it is opened and clamps the second fastener 12 inside, then the connector box 64 is reset, and in the process, the first T-shaped rod 62 first blocks the outlet of the second fastener 12 on the second storage box 61, and after recovery, the new second fastener 12 falls into the connector box 64, and in the process, the second extrusion plate 65 pushes the supporting frame 942 to make the clamping hand 9474 fit the outer wall of the first fastener 11, so as to facilitate subsequent screwing.

[0079] It should be noted that after the first installation assembly is installed, the adjusting assembly 93 releases the limiting of the fastening assembly 92, so that the pressure of the U-shaped clamping plate 921 on the spring wire tube 10 meets the installation stamping needs of the second fastener 12, and when the second fastener 12 is installed, the width is smaller than the distance required for the operation of the adjusting assembly 93, so that the adjusting assembly 93 will not trigger the limiting state of the fastening assembly 92; at the same time, the elastic flake is arranged on the side close to each other of the two U-shaped clamping plates 921, which hinders when the first fastener 11 is sleeved on the outer wall of the spring wire tube 10, preventing it from moving out together with the first arc-shaped sheet 925 again.

[0080] Further, as Figure 2 and Figure 5As shown, the discharge assembly 8 includes a second connecting rod 82 connected to a second T-shaped rod 81, a third extrusion plate 83 connected to one end of the second T-shaped rod 81 and used to drive the vertical rod 926 to open and the support frame 942 to reset, thereby releasing the fixation of the spring tube 10, and a collection box 84 for collecting the spring tube 10 is provided on the external frame 13.

[0081] The material blocking rod 54, the first connecting rod 63, the second connecting rod 82, and the cutting knife 421 are all connected to the output end of the drive cylinder 86 on the external frame 13 via the connecting frame 85 to work.

[0082] In this embodiment, by setting up the discharge component 8, the spring tube 10 that has completed the processing work can automatically complete the discharge work, reducing manual intervention and saving costs. At the same time, the connecting frame 85 connects the material blocking rod 54, the first connecting rod 63, the second connecting rod 82, and the wire cutter 421, thereby achieving consistent progress at each station, making the entire installation work run smoothly and in a coordinated manner, while saving power resources.

[0083] In detail, when the bearing mechanism 2 moves the spring tube 10 to the discharge station, after the first gear 338 and the first rack 339 below the external frame 13 are driven, the expansion component 33 contracts and cancels the tensioning work on the spring tube 10. Then, at the discharge station, the second connecting rod 82 and the second T-shaped rod 81 push the third extrusion plate 83 to separate the vertical rod 926. The fastening component 92 releases the clamping of the assembled spring tube 10. At the same time, the vertical rod 926 drives the second guide plate 928 to separate from the first guide plate 927, which facilitates the separation of the spring tube 10 from the rotating frame 91. The third extrusion plate 83 restores the support frame 942 to its initial position. Finally, after the second gear 929 and the second rack 9210 below the external frame 13 are driven, the rotating frame 91 returns to its initial position. At this time, the spring tube 10 falls into the collection box 84 under its own gravity without external support.

[0084] It should be noted that, under the action of the third pressing plate 83, the adjusting component 93 is driven to work, and the fastening component 92 is repositioned, so that it can fix the spring tube 10 again.

[0085] Example 2

[0086] like Figure 6 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0087] Furthermore, such as Figures 9-10As shown, the feeding mechanism 4 includes a wire feeding assembly 41 located above the support platform 32 for conveying the spring tube 10, and a wire cutting assembly 42 located inside the wire feeding assembly 41 for cutting the spring tube 10 to a fixed length.

[0088] In this embodiment, by setting up the wire feeding assembly 41 and the wire cutting assembly 42, the long spring tube 10 can be easily divided into the length required for processing, which facilitates processing. At the same time, automatic feeding reduces manual intervention and improves work efficiency.

[0089] Furthermore, such as Figures 9-10 As shown, the wire feeding assembly 41 includes a mounting ring 412 with a second toothed ring 411 connected to its inner wall and mounted on an external frame 13, a winding drum 413 connected to the bottom of the mounting ring 412, a wire feeding box 414 connected to the bottom of the mounting ring 412, and a drive gear 416 that drives the wire feeding box 414 to perform wire feeding and is synchronously driven by the drive motor 415 while meshing with the second toothed ring 411. The wire feeding box 414 is provided with two synchronous pulleys 418 that assist in wire feeding through a synchronous belt 417 and driven by the drive motor 415.

[0090] The wire cutting assembly 42 includes a wire cutting blade 421 corresponding to the insertion hole 420 on one side of the spool 413, and two wire support plates 422 symmetrically connected to the bottom of the spool 413 and used to support the spring wire tube 10. The two wire support plates 422 are respectively connected by a crossbar 424 on which a torsion spring 423 is installed.

[0091] In this embodiment, by setting a drive gear 416 and a second gear ring 411, the wire feeding box 414 is rotated around the winding drum 413 under the drive of the drive motor 415. At the same time, the drive motor 415 drives two synchronous pulleys 418 to rotate via the synchronous belt 417 to assist the spring wire tube 10 in conveying the wire. Under the action of the wire cutting assembly 42, the wire tube 10 is cut to a certain length, and then the support is released so that the spring wire tube 10 falls onto the corresponding bearing mechanism 2.

[0092] In detail, when the feeding is needed, firstly, the cutting wire cutter 421 is driven to move and insert into the insertion hole 420 on one side of the winding drum 413 under the action of the driving cylinder 86, so as to cut the spring wire tube 10, and the end of the cutting wire cutter 421 abuts against the connection of the two horizontal rods 424, so that the two horizontal rods 424 are folded, and the lifting of the spring wire tube 10 is cancelled, so that the spring wire tube 10 falls on the corresponding bearing mechanism 2 under the action of gravity, and then the driving motor 415 is started to rotate, the output end of the driving motor 415 drives the driving gear 416 to rotate in the second gear ring 411, so that the wire unwinding box 414 rotates around the winding drum 413 to unwind the wire, and the driving motor 415 drives the two synchronous wheels 418 to rotate through the synchronous belt 417 to assist the spring wire tube 10 to be conveyed.

[0093] It should be noted that when the spring wire tube 10 is initially placed, the end of the wire tube needs to be manually wound on the outer wall of the winding drum 413 for a certain length, so that the extended part can drive the subsequent spring wire tube 10 to continue to fall and wind on the outer wall of the winding drum 413 by using the gravity.

[0094] Working process:

[0095] The spring wire tube 10 completes the cutting work on the blanking station and falls on the bearing mechanism 2 to be transmitted by the power of the transmission mechanism 1, and then passes through the first fastener 11 loading station, the second fastener 12 loading station, the tightening station and the discharging station, respectively, to realize the assembly of the air pump accessory, and finally the spring wire tube 10 after the installation is inserted into the pressure tester by manual operation for air tightness detection.
