Description

Technical Field

[0001] The invention relates to the technical field of hair dryer assembly, in particular to an automatic positioning mechanism for a motor and a base and an automatic screw tightening device. Background Art

[0002] In the actual factory production scenario, the core component of the hair dryer, the blowing assembly, is basically still dependent on manual labor, which is too labor-intensive and lacks standardized management. For the two core power components, the motor and the base, the combination is fastened by two M2.5 screws. The specific assembly process of the motor and the base is as follows: manually grab the motor with one hand and the base with the other hand, and after the two components are aligned, the screw machine is used to absorb and tighten the screws into the base and the motor. The screws pass through the base light hole on the base and are tightened into the motor threaded hole on the motor, thereby achieving a firm fastening of the base and the motor. The above manual operation requires more than three actions, and the manual operation is relatively busy, which makes it easy to make mistakes. In addition, it is difficult to firmly fix the relative position between the components by hand alone, resulting in extremely low efficiency; and manually picking up the electric screwdriver head is also prone to injury accidents. Summary of the invention

[0003] The purpose of the present invention is to provide an automatic positioning mechanism for a motor and a base and an automatic screw tightening device, which can automatically align and fix the motor threaded hole and the base light hole so that the screw tightening mechanism can perform screw tightening operations without manual intervention throughout the process, which helps to improve production efficiency.

[0004] In a first aspect, the present invention provides an automatic positioning mechanism for a motor and a base, comprising:

[0005] The first positioning block is provided with a placement groove for placing the motor, and the placement groove is provided with pin clamping teeth for circumferential positioning of the pins of the motor;

[0006] A first manipulator is used to convey a motor to the first positioning block, and the first manipulator can drive the motor to rotate in the placement slot so that the motor pins abut against the pin teeth;

[0007] A second manipulator is used to convey the base to the first positioning block. The second manipulator is provided with a second positioning block. The second manipulator can drive the base to rotate on the motor. When the second positioning block abuts against the notch step of the base, the base light hole can be aligned with the motor threaded hole.

[0008] A pressing block, with a positioning pin and a positioning tooth on one side facing the first positioning block;

[0009] The driving assembly is used to drive the pressing block to move toward the first positioning block so that the positioning pin is inserted into the positioning notch of the base and the positioning tooth is inserted into the positioning hole of the motor.

[0010] The automatic positioning mechanism of the motor and the base provided by the present invention inserts one end of the motor with the motor pin into the placement groove by a first manipulator, and then drives the motor to rotate in the placement groove until the motor pin abuts against the pin tooth, thereby completing the automatic positioning of the motor; inserts the base onto the motor by a second manipulator, and then drives the base to rotate on the motor until the notch step abuts against the second positioning block, thereby completing the automatic alignment of the base light hole and the motor threaded hole; finally, the driving component drives the clamping block to move toward the first positioning block, inserts the positioning pin into the positioning notch of the base, and inserts the positioning tooth into the positioning hole of the motor, thereby completing the clamping and fixing of the base light hole and the motor threaded hole, thereby ensuring the firmness and stability of subsequent actions; in addition, the entire operation of the mechanism does not require manual intervention, which helps to improve production efficiency.

[0011] Furthermore, the circumference of the positioning pin toward one end of the first positioning block is gradually decreasing, and the circumference of the positioning tooth toward one end of the first positioning block is gradually decreasing.

[0012] By adopting the above technical solution, the ends of the positioning pin and the positioning tooth can play a preliminary guiding role. Even if there is a slight looseness between the motor and the base, the positioning pin and the positioning tooth can still be inserted into the positioning notch of the base and the positioning hole of the motor respectively, and the misaligned base light hole and motor threaded hole can be aligned again, which helps to reduce the probability of mechanism error and improve the operation stability of the mechanism.

[0013] Furthermore, the upper surface of the pin locking tooth is arranged with a sharp chamfer.

[0014] By adopting the above technical solution, when the motor pins descend above the pin clamping teeth and enter the placement slot, the upper surface of the pin clamping teeth can guide the motor to deflect by a certain angle, thereby ensuring that the motor can smoothly fall into the placement slot.

[0015] Furthermore, the driving assembly includes a driving cylinder and a driving rod, the driving cylinder is arranged below the first positioning block, the driving rod is movably arranged in the driving cylinder, the clamping block is arranged at one end of the driving rod away from the driving cylinder, and the driving cylinder can drive the clamping block to approach or move away from the first positioning block through the driving rod.

[0016] Further, the driving rod includes a first driving rod and a second driving rod, and the first driving rod and the second driving rod are arranged on opposite sides of the driving cylinder; the clamping block includes a first clamping block and a second clamping block, the first clamping block is arranged at an end of the first driving rod away from the driving cylinder, and the second clamping block is arranged at an end of the second driving rod away from the driving cylinder.

[0017] By adopting the above technical solution, two driving rods are driven to move by a driving cylinder, so as to realize the relative approach and separation of the first clamping block and the second clamping block, complete the fixation and avoidance of the motor and the base, and help to improve the compactness of the structure.

[0018] Furthermore, the first clamping block is provided with a first through hole for passing through one end of the second driving rod away from the second clamping block, and the second clamping block is provided with a second through hole for passing through one end of the first driving rod away from the first clamping block.

[0019] Furthermore, the driving assembly also includes a rotating cylinder, which is arranged below the driving cylinder and is used to drive the driving cylinder to rotate.

[0020] By adopting the above technical solution, when the number of the base optical holes and the motor threaded holes are two or more, the rotating cylinder can drive the driving cylinder to rotate. Since the first positioning block is arranged above the driving cylinder, the first positioning block can rotate accordingly after the driving cylinder rotates, so that the base optical holes and the motor threaded holes can be rotated to above the screw tightening points respectively, thereby meeting the needs of automatic screw tightening at multiple points.

[0021] Furthermore, the first manipulator includes a first clamping assembly and a first rotating assembly, the first clamping assembly is provided with a first clamping space for placing a motor, the first rotating assembly is arranged in the first clamping space, and the first rotating assembly is used to drive the motor to rotate in the first clamping space.

[0022] Furthermore, the second manipulator also includes a second clamping assembly, a second rotating assembly and an identification assembly, the second clamping assembly is provided with a second clamping space for placing a base, the second rotating assembly is arranged in the second clamping space, the second rotating assembly is used to drive the base to rotate in the second clamping space, the second positioning block and the identification assembly are both arranged on the second clamping assembly, the second positioning block is at a first height, the identification assembly is at a second height, the first height is greater than or less than the second height, the identification assembly can identify the base at the second height, when the identification assembly identifies that the base is rotated to the point where the notch step is offset from the second positioning block, the second clamping assembly releases its clamping of the base; the second clamping assembly can also clamp the base to the point where the notch step is at the first height, the second rotating assembly drives the base to rotate in the second clamping space so that the second positioning block abuts against the notch step.

[0023] By adopting the above technical solution, by arranging the identification component and the second positioning block at different heights of the second clamping component, when the notch step is at the second height, the identification component can identify the rotating base, and when the identification component recognizes that the notch step is misaligned with the second positioning block, the second rotating component is controlled to stop rotating, and the second clamping component inserts the base into the motor and releases the clamping of the base; after the second positioning block completes the avoidance of the notch step, the second clamping component can move again to clamp the base, at this time the notch step is at the first height, and the second rotating component drives the base to rotate on the motor again, so that the notch step abuts against the second positioning block, thereby aligning the base optical hole and the motor threaded hole.

[0024] In a second aspect, the present invention provides an automatic screw-tightening device for a motor and a base, comprising:

[0025] An automatic positioning mechanism for any of the above motors and bases;

[0026] The screw tightening mechanism is used to screw the screws into the base light hole and the motor threaded hole in sequence to complete the automatic positioning, so as to lock and fix the base on the motor.

[0027] As can be seen from the above, the automatic positioning mechanism of the motor and the base provided by the present invention inserts one end of the motor with the motor pin into the placement groove through the first manipulator, and the first manipulator drives the motor to rotate in the placement groove until the motor pin abuts against the pin tooth, thereby completing the automatic positioning of the motor; the base is inserted into the motor through the second manipulator, and the second manipulator drives the base to rotate on the motor until the notch step abuts against the second positioning block, thereby completing the automatic alignment of the base optical hole and the motor threaded hole; finally, the driving assembly drives the clamping block to move toward the first positioning block, inserts the positioning pin into the positioning notch of the base, and inserts the positioning tooth into the positioning hole of the motor, thereby completing the clamping fixation of the base optical hole and the motor threaded hole, thereby ensuring the firmness and stability of subsequent actions; in addition, the mechanism does not require manual intervention throughout the operation, which helps to improve production efficiency.

DETAILED DESCRIPTION

[0039] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0040] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0041] Reference Figure 1The automatic positioning mechanism of a motor and a base disclosed in the present invention is mainly used to align and fix the motor threaded hole 13 and the base light hole 23, so that the screw tightening mechanism 700 can perform the screw tightening operation. No manual intervention is required during the whole process, which helps to improve production efficiency. Specifically, the motor 10 is provided with a motor threaded hole 13 and a motor pin 11 at opposite ends, and the side of the motor 10 is also provided with a positioning hole 12; the base 20 is provided with a base light hole 23 corresponding to the motor threaded hole 13, and the side of the base 20 is also provided with a positioning notch 22, and the base 20 is also provided with a notch step 21 around the positioning notch 22.

[0042] Reference Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 6 In one embodiment, the automatic positioning mechanism of the motor and the base includes a first positioning block 100, a first manipulator 200, a second manipulator 300, a second positioning block 400, a clamping block 500 and a driving assembly 600. The first positioning block 100 is provided with a placement slot 110 for placing the motor 10, and the placement slot 110 is provided with pin teeth 111 for circumferential positioning of the motor pins 11; the first manipulator 200 is used to transport the motor 10 to the first positioning block 100, and the first manipulator 200 can drive the motor 10 to rotate in the placement slot 110 so that the motor pins 11 abut against the pin teeth 111; the second manipulator 300 is used to transport the base 20 to the first positioning block 100, and the second manipulator 300 is provided with a second positioning block 400 (as shown in the attached figure) Figure 6 As shown in the figure, the second manipulator 300 can drive the base 20 to rotate on the motor 10. When the second positioning block 400 abuts against the notch step 21 of the base 20, the base light hole 23 can be aligned with the motor threaded hole 13; the clamping block 500 is provided with a positioning pin 510 and a positioning tooth 520 on the side facing the first positioning block 100; the driving assembly 600 is used to drive the clamping block 500 to move toward the first positioning block 100, so that the positioning pin 510 is inserted into the positioning notch 22 of the base 20, and the positioning tooth 520 is inserted into the positioning hole 12 of the motor 10 (as shown in the figure). Figure 4 as shown).

[0043] It is worth noting that after the motor pin 11 and the pin tooth 111 are in contact, the position of the base light hole 23 on the first positioning block 100 is determined. At this time, the alignment method of the base light hole 23 and the motor threaded hole 13 can be that the second manipulator 300 first moves to a predetermined position to achieve the fitting of the motor 10 and the base 20, and then drives the notch step 21 and the second positioning block 400 to abut at a predetermined position, so that the base light hole 23 and the motor threaded hole 13 are aligned with each other.

[0044] As can be seen from the above, the automatic positioning mechanism of the motor and the base provided by the present invention inserts one end of the motor 10 having the motor pin 11 into the placement groove 110 by the first manipulator 200, and the first manipulator 200 then drives the motor 10 to rotate in the placement groove 110 until the motor pin 11 abuts against the pin clamping tooth 111, thereby completing the automatic positioning of the motor 10; inserts the base 20 onto the motor 10 by the second manipulator 300, and the second manipulator 300 then drives the base 20 to rotate on the motor 10 until the notch step 21 abuts against the first manipulator 300. The two positioning blocks 400 abut against each other, thereby completing the automatic alignment of the base optical hole 23 and the motor threaded hole 13; finally, the driving assembly 600 drives the clamping block 500 to move toward the first positioning block 100, inserting the positioning pin 510 into the positioning notch 22 of the base 20, and inserting the positioning tooth 520 into the positioning hole 12 of the motor 10, thereby completing the clamping and fixing of the base optical hole 23 and the motor threaded hole 13, ensuring the firmness and stability of subsequent actions; in addition, the entire operation of the mechanism does not require human intervention, which helps to improve production efficiency.

[0045] When the first manipulator 200 and the second manipulator 300 release the clamping of the motor 10 and the base 20, the motor 10 and the base 20 will inevitably become slightly loose on the first positioning block 100, thereby causing the alignment between the base light hole 23 and the motor threaded hole 13 to fail. To this end, in one embodiment, the circumference of the positioning pin 510 toward one end of the first positioning block 100 is gradually reduced, and the circumference of the positioning tooth 520 toward one end of the first positioning block 100 is gradually reduced.

[0046] By adopting the above technical solution, the ends of the positioning pin 510 and the positioning tooth 520 can play a preliminary guiding role. Even if there is a slight looseness between the motor 10 and the base 20, the positioning pin 510 and the positioning tooth 520 can still be inserted into the positioning notch 22 of the base 20 and the positioning hole 12 of the motor 10 respectively, and the misaligned base light hole 23 and the motor threaded hole 13 can be aligned again, which helps to reduce the probability of mechanism error and improve the operation stability of the mechanism.

[0047] When the motor 10 is directly lowered, the motor pin 11 may collide with the pin locking tooth 111. If the motor pin 11 is collided with hard, it is easy to damage the motor pin 11. Therefore, in one embodiment, the upper surface of the pin locking tooth 111 is set with a sharp chamfer.

[0048] With the above technical solution, when the motor pin 11 drops over the pin latch 111 and enters the placement slot 110 , the upper surface of the pin latch 111 can guide the motor 10 to deflect by a certain angle, thereby ensuring that the motor 10 can smoothly fall into the placement slot 110 .

[0049] Specifically, the upper surface of the pin locking tooth 111 is arranged in an inverted triangle shape to prevent the pin locking tooth 111 from colliding and interfering with the motor pin 11 .

[0050] In one embodiment, the driving assembly 600 includes a driving cylinder 610 and a driving rod 620. The driving cylinder 610 is disposed below the first positioning block 100. The driving rod 620 is movably disposed in the driving cylinder 610. The clamping block 500 is disposed at one end of the driving rod 620 away from the driving cylinder 610. The driving cylinder 610 can drive the clamping block 500 to move closer to or away from the first positioning block 100 through the driving rod 620.

[0051] In one embodiment, the driving rod 620 includes a first driving rod 621 and a second driving rod 622, and the first driving rod 621 and the second driving rod 622 are arranged on opposite sides of the driving cylinder 610; the clamping block 500 includes a first clamping block 531 and a second clamping block 532, and the first clamping block 531 is arranged at one end of the first driving rod 621 away from the driving cylinder 610, and the second clamping block 532 is arranged at one end of the second driving rod 622 away from the driving cylinder 610.

[0052] By adopting the above technical solution, a driving cylinder 610 drives two driving rods 620 to move, thereby realizing the relative approach and separation of the first clamping block 531 and the second clamping block 532, completing the fixation and avoidance of the motor 10 and the base 20, and helping to improve the compactness of the structure.

[0053] Specifically, the first clamping block 531 and the second clamping block 532 each include four fitting surfaces, two of which are used to fit with the motor 10, and the other two of which are used to fit with the base 20. When the positioning pin 510 and the positioning tooth 520 are inserted, the eight fitting surfaces will fit tightly with the motor 10 and the base 20, thereby completing the compression and fixation of the motor 10 and the base 20.

[0054] In one embodiment, the first clamping block 531 is provided with a first through hole 5311, and the first through hole 5311 is used for the second driving rod 622 to pass through one end away from the second clamping block 532, and the second clamping block 532 is provided with a second through hole 5321, and the second through hole 5321 is used for the first driving rod 621 to pass through one end away from the first clamping block 531.

[0055] In one embodiment, the driving assembly 600 further includes a rotating cylinder 630 . The rotating cylinder 630 is disposed below the driving cylinder 610 . The rotating cylinder 630 is used to drive the driving cylinder 610 to rotate.

[0056] By adopting the above technical solution, when the number of the base optical hole 23 and the motor threaded hole 13 are two or more, the rotating cylinder 630 can drive the driving cylinder 610 to rotate. Since the first positioning block 100 is arranged above the driving cylinder 610, when the driving cylinder 610 rotates, the first positioning block 100 can rotate accordingly, so that the base optical hole 23 and the motor threaded hole 13 can be rotated to the top of the screw tightening point respectively, meeting the needs of automatic screw tightening at multiple points.

[0057] Reference Figure 5 In one embodiment, the first manipulator 200 includes a first clamping assembly 210 and a first rotating assembly 220. The first clamping assembly 210 is provided with a first clamping space 211 for placing the motor 10. The first rotating assembly 220 is disposed in the first clamping space 211. The first rotating assembly 220 is used to drive the motor 10 to rotate in the first clamping space 211.

[0058] Specifically, the first rotating component 220 includes a first motor 221, a first synchronous belt 222, a first driving wheel 223 and a first driven wheel 224. The output end of the first motor 221 is connected to the first synchronous belt 222, and the first synchronous belt 222 is also connected to the first driving wheel 223. The first motor 221 can drive the first driving wheel 223 to rotate through the first synchronous belt 222. There are three first driven wheels 224. The first clamping component 210 can open or close the first clamping space 211. When the first clamping component 210 closes the first clamping space 211, the three first driven wheels 224 and the first driving wheel 223 cooperate to complete the clamping of the motor 10. The rotation of the first driving wheel 223 can drive the motor 10 to rotate.

[0059] Reference Figure 6 , Attachment Figure 7 , Attachment Figure 8In one embodiment, the second manipulator 300 further includes a second clamping assembly 310, a second rotating assembly 320 and an identification assembly 330. The second clamping assembly 310 is provided with a second clamping space 311 for placing the base 20. The second rotating assembly 320 is provided in the second clamping space 311. The second rotating assembly 320 is used to drive the base 20 to rotate in the second clamping space 311. The second positioning block 400 and the identification assembly 330 are both provided on the second clamping assembly 310. The second positioning block 400 is at a first height, and the identification assembly 330 is at a second height. At the two heights, the first height is greater than or less than the second height, and the identification component 330 can identify the base 20 at the second height. When the identification component 330 recognizes that the base 20 rotates to the point where the notch step 21 is offset from the second positioning block 400, the second clamping component 310 releases the clamping of the base 20; the second clamping component 310 can also clamp the base 20 to the point where the notch step 21 is at the first height, and the second rotating component 320 drives the base 20 to rotate in the second clamping space 311 to make the second positioning block 400 abut against the notch step 21.

[0060] By adopting the above technical solution, by arranging the recognition component 330 and the second positioning block 400 at different heights of the second clamping component 310, when the notch step 21 is at the second height, the recognition component 330 can recognize the rotating base 20, and when the recognition component 330 recognizes that the notch step 21 is staggered with the second positioning block 400, the second rotating component 320 is controlled to stop rotating (as shown in the attached figure). Figure 7 As shown in the figure, the second clamping assembly 310 inserts the base 20 onto the motor 10 and releases the clamping of the base 20; after the second positioning block 400 avoids the notch step 21, the second clamping assembly 310 can move again to clamp the base 20, at which time the notch step 21 is at the first height, and the second rotating assembly 320 drives the base 20 to rotate on the motor 10 again, so that the notch step 21 abuts against the second positioning block 400 (as shown in the figure). Figure 8 As shown), the base optical hole 23 and the motor threaded hole 13 are aligned.

[0061] Specifically, the identification component 330 can be a material optical fiber. The second rotating component 320 includes a second motor 321, a second synchronous belt 322, a second driving wheel 323 and a second driven wheel 324. The output end of the second motor 321 is connected to the second synchronous belt 322, and the second synchronous belt 322 is also connected to the second driving wheel 323. The second motor 321 can drive the second driving wheel 323 to rotate through the second synchronous belt 322. The number of the second driven wheels 324 is three. The second clamping component 310 can open or close the second clamping space 311. When the second clamping component 310 closes the second clamping space 311, the three second driven wheels 324 and the second driving wheel 323 cooperate to complete the clamping of the base 20. The rotation of the second driving wheel 323 can drive the base 20 to rotate.

[0062] Reference Figure 2 The present invention also provides an automatic screw tightening device for a motor and a base, comprising the automatic positioning mechanism for the motor and the base and a screw tightening mechanism 700 of any of the above embodiments. The screw tightening mechanism 700 is used to screw the screws into the base light hole 23 and the motor threaded hole 13 that have completed the automatic positioning in sequence, so as to lock and fix the base 20 on the motor 10.

[0063] Reference Fig. 9 In one embodiment, the screw tightening mechanism 700 includes a screw feeder 710, an electric screwdriver head 720, a horizontal drive cylinder assembly 730 and a vertical drive cylinder assembly 740. The screw feeder 710 is used to feed screws to the electric screwdriver head 720. The electric screwdriver head 720 is movably arranged on the vertical drive cylinder assembly 740. The vertical drive cylinder assembly 740 is movably arranged on the horizontal drive cylinder assembly 730. The horizontal drive cylinder assembly 730 and the vertical drive cylinder assembly 740 can drive the electric screwdriver head 720 to move to the output end of the screw feeder 710 to absorb the screw, and drive the electric screwdriver head 720 with the screw absorbed to the screw tightening point to screw the screw into the base light hole 23 and the motor threaded hole 13.

[0064] Specifically, when the number of the motor threaded holes 13 and the base light holes 23 is two, the operation process of the screw tightening mechanism 700 is as follows: the electric screwdriver head 720 picks up a screw and moves toward the first positioning block 100 under the drive of the horizontal drive cylinder assembly 730 and the vertical drive cylinder assembly 740. Since the cylinder has only one stroke, sucking the screw and tightening the screw each occupy one point, and there are two points where the screws need to be tightened. By setting the rotating cylinder 630, the other motor threaded hole is rotated to below the screw tightening point, waiting for the screw tightening mechanism 700 to tighten again.

[0065] In one embodiment, a through-shooting sensor 721 is provided at the output end of the screw feeder 710, and the through-shooting sensor 721 can detect the screws. When the through-shooting sensor 721 detects that there are screws at the output end of the screw feeder 710, the electric screwdriver head 720 absorbs the screws under the drive of the horizontal drive cylinder assembly 730 and the vertical drive cylinder assembly 740.

[0066] It is worth noting that the screw head is cross-shaped, and the electric screwdriver head 720 is also cross-shaped. When the electric screwdriver head 720 moves down to absorb, it is difficult to ensure that the two crosses fit closely together. Therefore, the electric screwdriver head 720 adopts a method of rotating and descending to absorb, so that the cross of the electric screwdriver head 720 can adaptively find the cross of the screw. In this way, it can be ensured that the screw is perpendicular to the ground and stable and secure, and the screw will not easily fall off the electric screwdriver head 720 during the movement.

[0067] In one embodiment, a magnet is further provided on the electric screwdriver head 720. By providing the magnet, the magnetic force of the electric screwdriver head 720 can be increased, and the stability of the screw on the electric screwdriver head 720 can be provided.

[0068] The present invention also provides an automatic screw tightening method for a motor and a base, comprising the following steps:

[0069] 1. The first manipulator 200 clamps one end of the motor 10 having the motor pin 11 into the placement slot 110;

[0070] 2. The first manipulator 200 drives the motor 10 to rotate in the placement slot 110 until the motor pin 11 abuts against the pin locking tooth 111;

[0071] 3. The second manipulator 300 clamps the base 20 and inserts it into the motor 10;

[0072] 4. The second manipulator 300 drives the base 20 to rotate on the motor 10 until the second positioning block 400 abuts against the notched step 21, completing the alignment of the base optical hole 23 and the motor threaded hole 13;

[0073] 5. The driving assembly 600 drives the pressing block 500 to move toward the first positioning block 100 until the positioning pin 510 is inserted into the positioning notch 22 of the base 20 and the positioning tooth 520 is inserted into the positioning hole 12 of the motor 10, thereby completing the pressing and fixing of the motor 10 and the base 20;

[0074] 6. The screw tightening mechanism 700 screws the screws into the base light hole 23 and the motor threaded hole 13 in sequence to complete the automatic positioning, so as to lock and fix the base 20 on the motor 10.
