Description

Technical Field

[0001] The present invention relates to the technical field of motor manufacturing, in particular to a full-automatic self-adaptive DC brushless motor riveting workstation. Background Art

[0002] Riveting is a process in which, under external pressure, the rivet causes the body material to plastically deform and squeeze into a specially designed prefabricated groove, thereby achieving a reliable connection between two parts. It applies pressure at the connection point, causing the material to plastically deform, thus forming a strong connection.

[0003] A brushless DC motor, consisting of an electric motor and a driver, is a typical mechatronic product. During the production of a brushless DC motor, riveting is primarily used on components such as the rotor, bracket, and housing. Riveting is also commonly used to connect the stator and housing of a brushless DC motor. During assembly, proper alignment between the stator core and housing is crucial, while also preventing deformation or damage to the stator during the riveting process.

[0004] The current assembly process typically involves first securing the stator, then placing the housing on top of the stator. The housing is then pressed down into position using riveting, held for a period of time, and then released. During this downward pressure, the housing creates friction with the stator surface. Excessive resistance can damage the housing surface and potentially the stator. Summary of the Invention

DETAILED DESCRIPTION

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1-15 The present invention provides a technical solution: a fully automatic adaptive DC brushless motor riveting workstation, including a frame 1, a riveting mechanism and a positioning mechanism. A workbench 11 is provided on the frame 1, and the positioning mechanism is provided on the workbench 11 for placing the stator 2 and the housing 3 and positioning or limiting them. The riveting mechanism is mounted on the upper side of the positioning mechanism for riveting the stator 2 and the housing 3 together.

[0041] like Figure 3 、 Figure 4 As shown, the riveting mechanism includes a cylinder 41, a fixed plate 42 and several guide rods 43. One end of the guide rod 43 is fixed on the workbench 11, and the other end of the guide rod 43 is connected to the fixed plate 42. The cylinder 41 is installed on the fixed plate 42. The driving end of the cylinder 41 is connected to the upper mold 44. The upper mold 44 includes an upper mold base 441, several upper mold pillars 442 and an upper mold ring 443. The upper mold pillars 442 are respectively connected to the upper mold base 441 and the upper mold ring 443. A lubrication component 5 is provided on the upper mold 44.

[0042] In actual operation, the upper die base 441 is connected to a slide plate 45, which slides with each guide rod 43. When the oil cylinder 41 is started, it drives the slide plate 45 to move up and down, thereby controlling the upper die 44 to perform riveting, and the guide rod 43 is used for guidance.

[0043] like Figure 5 、 Figure 6 As shown, the lubrication assembly 5 includes a slide plate 51, which is slidably matched with the upper mold support 442. The upper side of the slide plate 51 is connected to an electric push rod 52, which is fixed to the lower side of the upper mold base 441. A gear plate 53 is rotatably provided on the lower side of the slide plate 51. Several cylinders 54 are fixed on the circumference of the surface of the gear plate 53. The driving end of the cylinder 54 is connected to a movable seat 55. A groove is provided at the bottom of the movable seat 55, and several telescopic rods 56 are arranged at intervals in the groove. A connecting plate 57 is fixed to the telescopic end of the telescopic rod 56, and a sponge 58 is provided on the surface of the connecting plate 57. A lubricant cavity 551 is provided in the movable seat 55 and an oil channel 552 is provided to cooperate with each telescopic rod 56.

[0044] The telescopic rod 56 includes a sleeve 561, a moving rod 562 and a spring 563. The sleeve 561 is a hollow structure. The moving rod 562 slides with the sleeve 561. The spring 563 is arranged in the sleeve 561 and its two ends are respectively connected to the moving rod 562 and the moving seat 55. An oil channel interface 564 is provided on the moving rod 562, and the moving rod 562 opens toward one end of the connecting plate 57.

[0045] Supplementary explanations based on the above structure are as follows: the connecting plate 57 is provided with corresponding notches to cooperate with each moving rod 562. Preferably, a pressure sensing module is provided at the connection between the spring 1 563 and the moving seat 55 to detect the telescopic state of the moving rod 562. The sponge 58 is located on the lower side of the upper mold ring 443. In the initial state, the moving rod 562 extends out of the sleeve 1 561 under the force of the spring 1 563. At this time, the oil channel interface 564 deviates from the position of the oil channel 552, and no lubricant flows in the moving rod 562; when the cylinder 1 54 controls the moving seat 55 to advance outward and contacts the corresponding inner wall of the shell 3, the moving rod 562 is squeezed and compressed back into the sleeve 1 561. At this time, the oil channel interface 564 corresponds to the position of the oil channel 552. The lubricant flows through the oil channel 552 to the inside of the moving rod 562 and then flows to the sponge 58, thereby lubricating the inner wall of the shell 3.

[0046] Furthermore, the toothed disc 53 is provided with a gear 531, and the gear 531 is connected to a motor 59, which is fixed to the slide 2 51. In actual operation, the motor 59 starts to drive the gear 531 to rotate, thereby controlling each cylinder 1 54 to drive the moving seat 55 to rotate in a circle.

[0047] like Figure 2 As shown, the positioning mechanism includes a lower mold 6 and a set of limiting components 8. The lower mold 6 is installed on the workbench 11 and corresponds to the upper mold 44. The limiting components 8 are arranged on both sides of the lower mold 6.

[0048] like Figure 7 As shown, the lower die 6 includes a lower die base 61 , a lower die block 62 and a core rod 63 . The lower die block 62 is fixed on the lower die base 61 . A separation ring 621 is provided on the lower die block 62 . The core rod 63 is provided at the center of the lower die block 62 .

[0049] In actual operation, the stator 2 is sleeved on the outside of the core rod 63, the outer shell of the stator 2 is mounted on the separation ring 621, and the shell 3 is sleeved on the stator 2 before riveting. After riveting, the shell 3 moves down and is located outside the stator 2 to achieve a tight connection with the stator 2.

[0050] In one embodiment, Figure 8 As shown, the outer circumference of the separator ring 621 is provided with several long grooves 622, and the lower module 62 is provided with circular grooves 623 corresponding to each of the long grooves 622. The long grooves 622 are used to clear excess lubricant left on the inner wall of the housing 3, and the circular grooves 623 are used for confluence. Optionally, the circular grooves 623 are connected to a recovery pipeline for cleaning the accumulated lubricant inside.

[0051] like Figure 9 、 Figure 10As shown, the lower module 62 is provided with an annular air chamber 624 on the outside of the separation ring 621, a separation block 625 is provided in the annular air chamber 624, and air pumps 626 are respectively connected to the two sides of the separation block 625, and an air supply component 7 is provided at intervals in the annular air chamber 624.

[0052] like Figure 12 、 Figure 13 As shown, the air supply component 7 includes a sleeve 2 71, and a plurality of slide grooves 711 are spaced apart on the inner wall of the sleeve 2 71. A rotating cylinder 72 is provided in the sleeve 2 71, and the rotating cylinder 72 is rotatably provided in the annular air chamber 624. A slider 721 is provided on the upper side of the rotating cylinder 72 to cooperate with the slide groove 711, and an air inlet 722 is provided on the lower side of the rotating cylinder 72. A spring 2 73 is provided in the rotating cylinder 72, and one end of the spring 2 73 is connected to the wall of the annular air chamber 624, and the other end of the spring 2 73 is connected to the top cover 74, and the top cover 74 is fixedly connected to the sleeve 2 71.

[0053] Further, such as Figure 14 As shown, a plurality of vents 741 are provided on the circumference of the top cover 74, and a plurality of connecting grooves 712 are provided on the upper side of the sleeve 71. The connecting grooves 712 are staggered with the slide grooves 711. The lower module 62 cooperates with each air supply component 7 to provide corresponding circular holes 627. The circumference of the circular hole 627 is provided with blocks 628 whose number is the same as the connecting grooves 712.

[0054] It should be noted that the air inlet 722 of the drum 72 is located in the annular air chamber 624. When air flows into the annular air chamber 624, the air flows through the air inlet 722 into the drum 72 and the interior of the second sleeve 71 and is discharged from the air vent 741. The connecting groove 712 allows the block 628 to pass through.

[0055] Furthermore, a pair of deflection plates 75 are provided on the lower side of the rotating drum 72, and an electromagnetic block 629 is provided on the inner wall of the annular air chamber 624 to cooperate with the deflection plate 75. The side of the deflection plate 75 facing the electromagnetic block 629 is a magnetic surface, and the corresponding surface of the electromagnetic block 629 and the adjacent deflection plate 75 is an adsorption surface.

[0056] Supplementary explanation based on the above structure is as follows: When airflow flows in the annular air chamber 624 in the forward direction, the airflow pushes the corresponding deflector plate 75, causing the rotating drum 72 to deflect. The second sleeve 71 rotates synchronously, stopping after the deflector plate 75 engages the corresponding electromagnetic block 629. At this time, the connecting groove 712 is offset from the stopper 628, and the top cover 74 is blocked by the stopper 628, preventing the second sleeve 71 from moving upward. Simultaneously, the air inlet 722 is deflected to the windward side. Airflow from the annular air chamber 624 enters through the air inlet 722 and is transported upward through the vent 741, effectively cleaning impurities from the surface of the stator 2. When airflow flows in the reverse direction, the airflow pushes the corresponding deflector plate 75, causing the rotating drum 72 to deflect in the reverse direction. The second sleeve 71 rotates synchronously, stopping after the deflector plate 75 engages the corresponding electromagnetic block 629. At this time, the connecting groove 712 aligns with the stopper 628, and the top cover 74, driven by the airflow, drives the second sleeve 71 upward. Preferably, a tension sensing module is provided at the connection between the second spring 73 and the wall of the annular air chamber 624 to detect the tension state of the second spring 73. If the stator 2 and the housing 3 are riveted into place, the upper side of the second sleeve 71 is blocked by the housing 3 and cannot move upward. Otherwise, the second spring 73 can be pulled upward.

[0057] like Figure 15 As shown, the limiting assembly 8 includes a second cylinder 81, a knife holder 82 is provided at the driving end of the second cylinder 81, and a stop knife 83 is provided on the knife holder 82. In actual operation, a guide rail is provided between the knife holder 82 and the workbench 11 to guide the movement of the knife holder 82. The stop knife 83 is used to clamp the surface of the shell 3 to prevent vertical movement when the riveting mechanism is disengaged.

[0058] The specific implementation methods are as follows:

[0059] Step 1: Feeding: The stator 2 is placed on the core rod 63 manually or by an external feeding mechanism, and the housing 3 is placed on the stator 2;

[0060] Step 2: Pre-pressing: the riveting mechanism presses down the housing 3 so that the bottom portion of the housing 3 contacts and connects with the outer side of the stator 2, and then the riveting mechanism stops pressing down;

[0061] Step 3: Lubrication. The lubricating assembly 5 is activated. The sponge 58 squeezes the housing 3 to apply lubricant. The lubricant flows down the inner wall of the housing 3. At the same time, the toothed disc 53 controls the rotation of the sponge 58 to ensure that the lubricant can cover the entire housing.

[0062] Step 4: Riveting, the lubrication assembly 5 stops lubrication, the electric push rod 52 pulls the sponge 58 up to a height higher than the bottom surface of the upper die ring 443, and the riveting mechanism continues to press the shell 3 until the bottom surface of the shell 3 contacts the surface of the lower die block 62;

[0063] Step 5: Maintain pressure. After the riveting mechanism rivets the shell 3 into place, maintain pressure for 0.5 seconds.

[0064] Step 6: Disengagement, the limit assembly 8 is pushed toward the shell 3, and after being stuck on the surface of the shell 3, the riveting mechanism is lifted up and separated from the shell 3, and the limit assembly 8 is reset to release the restriction;

[0065] Step 7: Detecting the discharge, the air supply component 7 detects whether the shell 3 is riveted into place, and discharges the material after marking.

[0066] Specifically, after the stator 2 is sleeved on the core rod 63 in step 1, air flow can be delivered through the air supply component 7 to clean impurities on its outer surface. Before the shell 3 is placed on the stator 2, the inner wall of the shell 3 can also be cleaned through the air supply component 7.

[0067] In step seven, assuming that the air flow state in the air supply assembly 7 is stable, the riveting state is classified as follows according to the feedback signal from the tension sensing module.

[0068] When the tension sensing modules detect no force signal, it indicates that the housing 3 has been riveted into place, the top covers 74 are blocked by the housing 3, and the second spring 73 is not stretched.

[0069] When each tension sensing module detects the same force signal, it indicates that the shell 3 has not been pressed down into place and is still some distance away from the surface of the lower module 62. At this time, the top cover 74 is pushed up by the airflow and presses against the lower side of the shell 3. The second spring 73 is stretched to the same length. At this time, the riveting mechanism should be controlled to press down for the second time to rivet it into place.

[0070] When each tension sensing module detects different force signals, it indicates that the shell 3 is misaligned with the stator 2 during the pressing process, so that the shell 3 is not pressed into place and the bottom surface height is inconsistent. At this time, it is necessary to immediately check whether the shell 3 and the stator 2 have surface deformation or damage.
