Description

Technical Field

[0001] This invention relates to the field of household appliance motor manufacturing equipment, and in particular to an automatic DC stator assembly and welding equipment. Background Technology

[0002] Currently, the assembly, welding, and testing of existing motor terminals in the market require at least three people to complete this task. This results in a large number of personnel, low labor efficiency, high labor costs, slow production speed, and unstable production quality.

[0003] Patent document CN114378464A discloses an automatic assembly and welding equipment for motor terminals. This equipment can effectively realize stator feeding, terminal assembly, terminal welding, defective product detection, defective product rejection, and qualified product unloading. Through the control operation of the six-station turntable, it can realize the parallel processing of six stations in an assembly line, effectively realizing the automated assembly and welding of stator terminals, greatly improving production efficiency, reducing labor costs, and improving product quality. However, this equipment only performs inspection after the stator and terminals are welded, which cannot eliminate defects before welding, resulting in low detection accuracy. Furthermore, the use of two stations to complete the rejection of defective products and the unloading of qualified products increases the operating time of the equipment, and the production efficiency is still not high enough. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide an automatic DC stator assembly and welding equipment. Through the control operation of the six-station split turntable and the terminal welding assembly, the equipment can realize stator feeding, stator coil pin detection, fixed plate feeding and assembly, fixed plate height detection, terminal welding, terminal pin detection, and stator unloading. This effectively realizes the automated terminal assembly and welding of the stator, further improving production efficiency and ensuring product quality.

[0005] The objective of this invention is achieved through the following technical solution:

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Figures 1-10 The automatic DC stator assembly and welding equipment of the present invention includes a machine base 10, a dividing turntable assembly 20, a human-machine interaction control device 30, a stator feeding assembly 40, a stator coil pin detection assembly 50, a fixed plate feeding and assembly assembly 60, a fixed plate height detection assembly 70, a terminal welding assembly 80, a terminal pin detection assembly 90, and a unloading assembly 100.

[0046] In this embodiment:

[0047] like Figure 3 As shown, the dividing turntable assembly 20 is set on the machine base 10, specifically including a turntable 21, a divider 22, and a workpiece positioning fixture 23. The divider 22 is connected to the turntable 21 by transmission. The turntable 21 has six stations, and each station is provided with a workpiece positioning fixture 23 to position the stator 110.

[0048] The human-machine interaction control device 30 is communicatively connected to the dividing turntable assembly 20, the stator feeding assembly 40, the stator coil pin detection assembly 50, the fixed plate feeding and assembly assembly 60, the fixed plate height detection assembly 70, the terminal welding assembly 80, the terminal pin detection assembly 90, and the unloading assembly 100.

[0049] like Figure 1-2 As shown, the stator feeding assembly 40, stator coil pin detection assembly 50, fixed plate feeding assembly 60, fixed plate height detection assembly 70, terminal pin detection assembly 90, and unloading assembly 100 are arranged in a row around the dividing turntable assembly 20 in the order of workstations.

[0050] like Figure 4 As shown, the stator feeding assembly 40 includes a rotary positioning mechanism 41 and a clamping mechanism 42.

[0051] The rotary positioning mechanism 41 includes a clamping drive 411, a clamping finger 412, a rotation positioning sensor 413, a linear guide rail 414, a loading base 415, and a sliding plate 416. The clamping drive 411 is mounted on the loading base 415 and is connected to the clamping finger 412. The clamping drive 411 drives the clamping finger 412 to move to limit the position of the stator 110. The rotation positioning sensor 413 is located on one side of the clamping drive 411 and is used to sense whether the part of the stator 110 to be assembled has rotated into position. The linear guide rail 414 is mounted on the loading base 415, and the sliding plate 416 is slidably mounted on the linear guide rail 414. The clamping drive 411 is mounted on the sliding plate 416.

[0052] The clamping mechanism 42 includes a translation module 421 and a clamping component 422. The clamping component 422 includes a gripper 4221 and a slider 4222. The translation module 421 is disposed above the machine base 10, and the slider 4222 is slidably mounted on the translation module 421. When the stator 110 rotates to the position, the clamping component 422 moves on the translation module 421 and places the stator 110 into the corresponding station on the turntable 21 through the gripper 4221, thereby completing the loading action.

[0053] like Figure 5 As shown, the stator coil pin detection assembly 50 includes a mounting frame 51, a light source 52, a stator coil pin detection camera 53, and a vibratory feeder detection camera 54. The mounting frame 51 is mounted on the machine base 10 and located on one side of the turntable 21. The light source 52 and the stator coil pin detection camera 53 are mounted on the mounting frame 51. The stator coil pin detection camera 53 is used to take pictures of the stator coil pins before assembly. The vibratory feeder detection camera 54 is used to take pictures of the fixing plate 120 inside the vibratory feeder 61. The above settings can remove defective stators 110 before assembly.

[0054] like Figure 6 As shown, the fixed plate loading and assembly assembly 60 includes a vibratory feeder 61, a vertical platform 62, and a robot arm 63. The vibratory feeder 61 stores multiple fixed plates 120 and outputs the fixed plates 120 in an orderly manner. The robot arm 63 is rotatably mounted on the vertical platform 62. The robot arm 63 includes a pressing drive cylinder 631, a fixing block 632, and two guide blocks 633. The fixing block 632 is located at the end of the pressing drive cylinder 631. The two guide blocks 633 are arranged opposite each other at the bottom of the fixing block 632, and a snap-fit ​​area is formed between them. The snap-fit ​​area is used to clamp the fixed plate 120. The robot arm 63 clamps the fixed plate 120 through the two guide blocks 633 and installs it onto the part of the stator 110 to be assembled. This structure can easily realize the movement and assembly pressing of the fixed plate 120.

[0055] like Figure 7As shown, the fixed plate height detection assembly 70 includes a bracket 71 and a height detection camera 72. The bracket 71 is mounted on the machine base 10 and located on one side of the turntable 21. The height detection camera 72 is mounted on the bracket 71 and faces the side of the fixed plate 120. This arrangement can remove defective stators 110 after assembly and before welding, thereby eliminating defects in stators 110 before welding and improving detection accuracy.

[0056] like Figure 8 As shown, the terminal welding assembly 80 is disposed between the terminal pin detection assembly 90 and the unloading assembly 100, and specifically includes a mounting base 81, a welding rotation drive component 82, a welding positioning fixture 83, a welding head 84, a sliding servo 85, a lifting servo 86, a welding head cleaning assembly 87, and a support base 88.

[0057] Mounting base 81 is set on machine base 10. Welding rotary drive component 82 and welding positioning fixture 83 are both set on mounting base 81. Sliding servo 85 is set on bracket base 88. Lifting servo 86 is set on sliding servo 85. Welding head 84 is set at the end of lifting servo 86. The extension direction of welding head 84 is parallel to the axial direction of sliding servo 85. This structure can effectively realize the automatic feeding of welding head 84. The position of welding head 84 is controlled in both horizontal and vertical directions by sliding servo 85 and lifting servo 86, and moves to the welding point to realize automatic welding of terminals.

[0058] The welding head cleaning assembly 87 includes a brush head 871, a brush head rotation drive 872, and a lifting servo 873. The brush head rotation drive 872 is mounted on the lifting servo 873 and is connected to the brush head 871 in a transmission manner. The extension direction of the brush head 871 is perpendicular to the extension direction of the welding head 84. The lifting servo 873 drives the brush head rotation drive 872 and the brush head 871 to move up and down. When the brush head 871 comes into contact with the welding head 84, the brush head rotation drive 872 drives the brush head 871 to rotate in order to clean the welding head 84.

[0059] In this application, the welding station is not directly set on the turntable 21, but is set separately on one side of the turntable 21. This makes it easier to rotate and adjust the part to be welded, and also avoids the welding wire from falling onto the turntable 21 and causing contamination. It also makes it easier to clean the welding head 84, improves efficiency, and reduces production costs.

[0060] like Figure 9 As shown, the terminal pin detection assembly 90 includes a coil pin detection camera 91, a ring light source 92, and a mounting bracket 93. The mounting bracket 93 is mounted on the machine base 10 and located on one side of the turntable 21. The ring light source 92 and the coil pin detection camera 91 are mounted on the mounting bracket 93. The coil pin detection camera 91 is used to take pictures and inspect the stator 110 after welding.

[0061] like Figure 10 As shown, the unloading assembly 100 includes a base 101, a transverse drive device 102, a lifting drive device 103, a clamping drive device 104, a stator clamping claw 105, a full material detection sensor 106, a defective product flow channel 107, a good product flow channel 108, and a baffle 109.

[0062] The base 101 is mounted on the machine tool 10. The transverse drive device 102 is mounted on the upper part of the base 101. The lifting drive device 103 is connected to the drive end of the transverse drive device 102. The clamping drive device 104 is connected and fixed to the drive end of the lower end of the lifting drive device 103. The drive end of the clamping drive device 104 faces downward and is connected to a stator clamping claw 105. The defective product flow channel 107 and the good product flow channel 108 are arranged in layers on the base 101. Specifically, the defective product flow channel 107 is located above the good product flow channel 108 and the two are parallel to each other. The extension direction of the good product flow channel 108 is perpendicular to the transverse drive device 102.

[0063] Both the full-material detection sensor 106 and the divider 109 are mounted on the base 101. The detection head of the full-material detection sensor 106 is aligned with the electronic full position of the defective product flow channel 107. After the full-material detection sensor 106 detects that the defective product flow channel 107 is full of defective products, it will transmit a signal to the human-machine interaction control device 30 to trigger an alarm and notify the operator to clean it in time. Multiple dividers 109 are set in the defective product flow channel 107 to classify defective products. In this application, there are classifications such as pin defects, solder joint defects, and visual defects, which facilitates employee re-inspection and improves rework efficiency.

[0064] The working principle of this application is as follows:

[0065] Under the control of the human-machine interaction control device 30, the stator feeding assembly 40 transports the stator 110 to be assembled to the feeding station on the turntable 21. The divider 22 drives the turntable 21 to rotate one station angle, moving the already fed stator 110 to the station where the stator coil pin detection assembly 50 is located for pre-assembly defect detection. After the preliminary detection is completed, the divider 22 drives the turntable 21 to rotate one station angle, moving the good product to the station where the fixed plate feeding assembly assembly 60 is located, where the fixed plate 120 is assembled by the robot arm 63. After the assembly is completed, the turntable 21 continues to rotate, moving the assembled stator 110 to the station where the fixed plate height detection assembly 70 is located for pre-welding detection. After the detection is completed, the turntable 21 continues to rotate, moving the assembled stator 110 to the station where the terminal pin detection assembly 90 is located, and the stator 110 is transferred by the transfer device. 10. The stator 110 is transferred to the station where the terminal welding assembly 80 is located for welding. After welding, the stator 110 is transferred back to the station where the terminal pin detection assembly 90 is located by the transfer device for post-weld inspection. Under the judgment and control of the human-machine interaction control device 30, defective and good products are classified. After the inspection, the turntable 21 continues to rotate to another station, so that the inspected stator 110 reaches the station where the unloading assembly 100 is located. The stator gripper 105 unloads the good products into the good product flow channel 108 and the defective products into the defective product flow channel 107. When working at the next station, the previous station performs its work tasks at the same time, so that the work of each station can be processed in parallel, effectively realizing the assembly and welding of the fixed plate 120 in a production line, which greatly improves production efficiency, reduces labor costs, and improves product quality.

[0066] This application uses the stator coil pin detection component 50 to perform preliminary inspection of the stator 110 before assembly, the fixed plate height detection component 70 to perform secondary inspection of the stator 110 after assembly, and the terminal pin detection component 90 to perform final inspection of the stator 110 after welding. This can eliminate defective products before welding and greatly improve the inspection accuracy. This application only sets up one station on the turntable 21 for unloading defective and good products, which shortens the working time of the equipment and further improves the production efficiency. The components of this application are compactly arranged and occupy less space.

[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
