DETAILED DESCRIPTION

[0027] In order to further understand the features, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0028] Referring to Figures 1-3 As shown in the figure, a motor stator and coil automatic attaching equipment comprises a casing 1, a conveying belt 2 arranged at the top of the casing 1 and used for conveying motor stator coils to be attached and a rotating table 3 arranged at the top of the casing 1 and used for receiving the motor stator coils to be attached on the conveying belt 2, and a material placing block 31 arranged on the rotating table 3, and the automatic attaching equipment further comprises an attaching mechanism 4 and a clamping and overturning mechanism 5; the attaching mechanism 4 is arranged at the top of the casing 1 and located at one side of the rotating table 3; the clamping and overturning mechanism 5 is arranged at the top of the casing 1 and located at one side of the rotating table 3; the clamping and overturning mechanism 5 comprises a sliding seat 51, a setting plate 52 and an overturning frame 53 arranged rotatably on the sliding seat 51, and a clamping part 54 arranged on the overturning frame 53 and used for clamping the motor stator coils to be attached received on the rotating table 3.

[0029] The rotating table 3 is preferably a motor rotating table, the conveying belt 2 is provided with a rotating driver for driving the conveying belt 2 to run, and the conveying belt 2 is further provided with a pushing cylinder; when the motor stator coil to be assembled is conveyed to one side of the pushing cylinder, the pushing cylinder is started and pushes the motor stator coil to be assembled onto the material placing block 31. In the initial state, the coil has been pre-inserted into the through hole of the motor stator to be assembled, but the coil and the motor stator to be assembled have not been assembled at this time. The material placing block 31 is designed with a plurality of matching grooves 311, the size of the matching grooves 311 is smaller than the size of the motor stator coil to be assembled, and the matching grooves 311 are used to provide abutment when the coil falls. When the motor stator coil to be assembled is located in the material placing block 31 and just above the matching grooves 311, the coil can smoothly fall and stably abut in the matching grooves 311. When it is necessary to assemble the motor stator coil to be assembled on the material placing block 31, the assembling mechanism 4 can be started to press assemble the motor stator coil to be assembled in the material placing block 31. After the first press assembly is completed, the sliding seat 51 is driven to move, and the setting plate 52 is synchronously moved, until the turnover frame 53 is close to the motor stator coil to be assembled which has completed the first assembly and is supported on the rotating table 3. At this time, the turnover frame 53 is turned down, so that the clamping part 54 of the turnover frame 53 is close to and clamps the two sides of the motor stator coil to be assembled. The clamping part 54 is integrated with a telescopic cylinder, which is used to drive the clamping part 54 to clamp. When the motor stator coil to be assembled is stably clamped by the clamping part 54 and has completed the first assembly, the turnover frame 53 is turned up and positioned above the rotating table 3. Then, the assembling mechanism 4 is started again to press assemble the unpress assembled side of the motor stator coil which has completed the first press assembly. The technical problem that the motor stator coil is not convenient to be press assembled on the upper and lower two sides in the prior art is effectively solved.

[0030] Referring to Figures 4-6 As shown in the figure, the clamping and turnover mechanism 5 further comprises a mounting plate 55, a first linear driver 56 and a screw rod 57; the mounting plate 55 is arranged on the casing 1 and located at one side of the conveying belt 2; the first linear driver 56 is arranged on the mounting plate 55 and located at one side of the assembling mechanism 4; the screw rod 57 is arranged at the output end of the first linear driver 56, and the screw rod 57 is threadedly connected with the sliding seat 51; when the screw rod 57 rotates, the sliding seat 51 is in a horizontal linear sliding state.

[0031] When the motor stator coil to be assembled completes the first press assembly, the sliding seat 51 is away from the motor stator coil to be assembled at this time, the first linear driver 56 is started, the first linear driver 56 drives the screw rod 57 to rotate, and the screw rod 57 drives the threadedly connected sliding seat 51 to slide horizontally along the mounting plate 55 when rotating.

[0032] Referring to Figures 4-6As shown, the clamping and overturning mechanism 5 further comprises a positioning column 58, a first rotary driver 59, a second rotary driver 591, a first gear 592 and a second gear 593; the positioning column 58 is installed on the setting plate 52, and the overturning frame 53 is coaxially fixed with the positioning column 58; the first rotary driver 59 is installed on the sliding seat 51, and the output end of the first rotary driver 59 is connected with the setting plate 52; the second rotary driver 591 is installed on the setting plate 52 and located at one side of the positioning column 58; the first gear 592 is arranged at the output end of the second rotary driver 591; and the second gear 593 is installed outside the positioning column 58 and meshes with the first gear 592.

[0033] During the movement of the sliding seat 51, the setting plate 52 can be synchronously moved until the setting plate 52 is located above the motor stator coil to be assembled. At this time, the second rotary driver 591 is started, and drives the first gear 592 to start rotating. The rotation of the first gear 592 further drives the second gear 593 meshing therewith to rotate. With the rotation of the second gear 593, the positioning column 58 and the overturning frame 53 will be overturned in the direction of approaching the motor stator coil to be assembled. After the overturning action is completed, the telescopic cylinder is started immediately to push the clamping part 54 to stably clamp the motor stator coil which has completed the first press-fitting. After the clamping operation is completed, the first rotary driver 59 is started, which drives the setting plate 52 and the overturning frame 53 to rotate as a whole, so as to rotate the motor stator coil after the first assembly, so that the un-assembled side of the motor stator coil faces the lower side of the assembly mechanism 4. Then the second rotary driver 591 drives the second gear 593 to rotate reversely, drives the overturning frame 53 to overturn the motor stator coil clamped by the clamping part 54 back to the placement block 31. Finally, the first linear driver 56 is started to drive the sliding seat 51 to slide in the horizontal direction away from the placement block 31, so as to prepare for the subsequent assembly operation.

[0034] Referring to Figures 4-6 As shown, the clamping and overturning mechanism 5 further comprises a sliding rod 594, a telescopic spring 595 and an abutting block 596; the sliding rod 594 has a pair of sliding rods arranged on the sliding seat 51 respectively, and the sliding rod 594 is located below the setting plate 52; one end of the telescopic spring 595 is fixed with the sliding seat 51, and the other end of the telescopic spring 595 is fixed with the sliding rod 594; and the abutting block 596 is arranged on the sliding rod 594, and when the sliding seat 51 slides, the abutting block 596 is in contact with the motor stator coil to be assembled.

[0035] When the sliding seat 51 slides horizontally towards the motor stator coil to be assembled, the abutting block 596 can first contact and abut against the motor stator coil to be assembled placed in the material placing block 31, and the sliding rod 594 can slide horizontally along the sliding seat 51, so that displacement of the assembling mechanism 4 during assembly of the motor stator coil to be assembled is prevented.

[0036] Referring to Figures 7-9 As shown in the figure, the assembling mechanism 4 comprises a punch 41, a punch block 42 and abutting blocks 43; the punch 41 is arranged on the top of the casing 1 and above the rotating table 3; the punch block 42 is arranged on the output end of the punch 41 and above the rotating table 3; the abutting blocks 43 are arranged on the punch block 42.

[0037] When the sliding seat 51 slides horizontally towards the motor stator coil to be assembled, the abutting block 596 can first contact the motor stator coil to be assembled placed in the material placing block 31. During the contact, the sliding rod 594 can smoothly slide horizontally along the guide structure of the sliding seat 51. This ensures that the coil can remain stable during assembly of the motor stator coil to be assembled by the assembling mechanism 4, effectively preventing displacement due to force during assembly, thereby improving the accuracy and reliability of assembly.

[0038] Referring to Figure 8 and Figure 9 As shown in the figure, the punch block 42 is provided with sliding cavities 421 for sliding of the abutting blocks 43; the punch block 42 is provided with a return spring 44 arranged in the sliding cavities 421, one end of the return spring 44 is fixed to the sliding cavities 421, and the other end of the return spring 44 is fixed to the abutting blocks 43; the sliding cavities 421 are provided with an energizing switch 45 in contact with the abutting blocks 43.

[0039] During descent of the punch block 42, the abutting blocks 43 first contact the coil on the motor stator under the elastic force of the return spring 44, and apply an abutting force to the coil, so that the coil is in a state of mutual lapping on the motor stator. With continuous descent of the punch block 42, the abutting blocks 43 slide in the sliding cavities 421, and the return spring 44 is gradually compressed. When the abutting blocks 43 slide to contact the energizing switch 45 in the sliding cavities 421, the abutting blocks 43 slide to contact the energizing switch 45 in the sliding cavities 421, and the welding operation is triggered. At this time, the abutting blocks 43 not only maintain the mutual lapping state of the coil, but also control the coil in the lapping state on the motor stator to be welded through the energizing switch 45, thereby realizing stable connection of the coil and the motor stator.

[0040] The working principle is as follows: when the motor stator coil to be assembled is completed with the first pressing assembly, the sliding seat 51 is away from the coil. At this time, the first linear driver 56 is started to drive the screw rod 57 to rotate. The rotation of the screw rod 57 drives the sliding seat 51 to slide horizontally along the mounting plate 55 through the threaded connection. In this process, the sliding seat 51 synchronously drives the setting plate 52 to move until the setting plate 52 is above the motor stator coil to be assembled. Then, the second rotary driver 591 is started to drive the first gear 592 to rotate. The rotation of the first gear 592 further drives the second gear 593 engaged with the first gear 592 to rotate. With the rotation of the second gear 593, the positioning column 58 and the turnover frame 53 are turned over in the direction of approaching the motor stator coil to be assembled. After the turnover action is completed, the telescopic cylinder is started to push the clamping part 54 to stably clamp the motor stator coil completed with the first pressing assembly. After the clamping operation is completed, the first rotary driver 59 is started to drive the setting plate 52 and the turnover frame 53 to rotate integrally, so that the motor stator coil assembled for the first time is rotated to the side not assembled to face downward of the assembling mechanism 4. Then, the second rotary driver 591 drives the second gear 593 to rotate reversely, so that the turnover frame 53 turns over the motor stator coil clamped by the clamping part 54 to the setting block 31. Next, the first linear driver 56 is started again to drive the sliding seat 51 to slide horizontally away from the setting block 31, so as to prepare for the subsequent assembling operation. When the sliding seat 51 slides in the direction of approaching the motor stator coil to be assembled, the abutting block 596 first contacts and abuts against the motor stator coil placed in the setting block 31. At this time, the sliding rod 594 can smoothly slide horizontally along the guide structure of the sliding seat 51, so as to prevent the assembling mechanism 4 from moving when the motor stator coil to be assembled is assembled. In the assembling process, when the stamping block 42 descends, the abutting block 43 first contacts the coil on the motor stator under the elastic force of the reset spring 44, and applies the abutting force to the coil, so that the coil reaches the state of mutual lap joint on the motor stator. With the continuous descent of the stamping block 42, the abutting block 43 slides in the sliding cavity 421, and the reset spring 44 is gradually compressed. When the abutting block 43 contacts the power-on switch 45 in the sliding cavity 421, the welding operation is triggered. At this time, the abutting block 43 not only maintains the mutual lap joint state of the coil, but also sets the control of the power-on switch 45 to weld the coil in the lap joint state on the motor stator, so as to realize the stable connection of the coil and the motor stator.

[0041] The above embodiment only expresses one or several embodiments of the present application, and the description is relatively specific and detailed, but it cannot be understood as the limitation of the scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
