Description

Technical Field

[0001] The invention relates to intelligent assembly equipment for installing two insulating sheets on a motor stator, belonging to the technical field of micro-motor production and assembly. Background Art

[0002] The micro-motor manufacturing industry has always been a labor-intensive industry. Due to the special nature of its products, it has not been able to achieve automated production. The assembly and production of motor stators and insulation sheets are all done using semi-automatic machines or fully manual operations. However, both semi-automatic and manual production have high costs, high labor intensity, low efficiency, and are prone to mis-installation or missing parts. The quality cannot be effectively guaranteed, and the qualified rate of finished products is low. With the current increase in labor costs and the widening gap in labor demand, it has become difficult to meet the needs of some micro-motor manufacturers.

[0003] In recent years, with the vigorous development of the automotive parts and power tool industries and the increasingly widespread application of various electrical products, the output and quality of micro motors are in need of a major improvement. Traditional manual or semi-automatic equipment for installing motor insulation sheets can no longer meet the requirements of product efficiency and product quality. Market factors require reducing labor cost input and improving production efficiency. There is a great need for highly automated stator insulation sheet intelligent assembly equipment. Summary of the Invention

[0004] The purpose of the present invention is to address the deficiencies of the existing technology and provide an intelligent assembly device for installing upper and lower insulating sheets on a motor stator, replacing manual or semi-automatic assembly of insulating sheets. The device is equipped with an insulating sheet feeding and processing mechanism, a rotating pre-assembly mechanism, a closing assembly mechanism, a flipping mechanism, a coding mechanism, a detection mechanism, and corresponding supporting conveying, detection, and positioning devices, thereby ensuring the product quality after the stator and the two insulating sheets are assembled, making clamping convenient and quick, and improving assembly safety.

[0005] The objective of the present invention is achieved through the following technical solutions: An intelligent assembly device for motor stator insulation sheets includes a frame and a pallet conveyor installed at the front end of the frame, a turnover conveyor at the lower part of the rear end of the frame, and a set of material sorting devices, a rotary pre-installation mechanism, a transverse movement mechanism and a closing mechanism are respectively provided on both sides of the frame. A lifting mechanism, a robot and a flipping mechanism are sequentially installed in the middle of the frame from the rear end, and a coding mechanism and a detection mechanism are installed at the front end of the right side of the frame. A plurality of work pallets and a lifting mechanism are provided on the pallet conveyor of the frame, and the lifting mechanism can control the positioning and transportation of the work pallets on the pallet conveyor. A batch of insulating sheets are manually placed on the vibrating plate and sorted and lined up by the material sorting device. The motor stator is input from the turnover conveyor table along with the turnover box. The turnover box is positioned and lifted by the lifting mechanism. The robot grabs the stator and insulating sheet in turn and places them on the respective positioning molds of the rotary pre-installation mechanism. The rotary pre-installation mechanism rotates 180 degrees and places the end with the stator and insulating sheet close to the closing device. The transverse mechanism grabs the stator and insulating sheet in turn and puts them into the closing mechanism. The closing mechanism tightens the lower end of the insulating sheet and installs it into the stator silicon steel sheet. After the A-side insulating sheet is installed, the transverse mechanism transfers the stator to the working tray positioned and lifted by the lifting mechanism on the pallet conveyor table. The stator and the working pallet are transported from the pallet conveyor table to the flipping station through the flipping The mechanism flips 180 degrees and then transports it to the B-side insulating sheet installation station. The transverse mechanism places the stator equipped with the A-side insulating sheet into the B-side closing mechanism. The transverse mechanism then grabs the insulating sheet and places it into the B-side closing mechanism to complete the assembly operation of installing the B-side insulating sheet into the stator. Finally, the transverse mechanism takes out the stator with insulating sheets on both sides and places it on the work tray. The stator is then marked by the coding mechanism. Finally, the status of the assembled product is detected by the inspection mechanism. Each station is equipped with detection and sensor components to detect the assembly status of the insulating sheet in real time. Unqualified products are automatically rejected and discharged. The labor intensity is low, which greatly improves product quality. The stator assembled with double-sided insulating sheets is automatically output after passing the inspection, which is convenient for connection with the previous and next processes.

[0006] The present invention provides an intelligent assembly device for double-sided installation of insulating sheets on motor stator silicon steel sheets. The device is equipped with an insulating sheet sorting mechanism, a rotary pre-installation mechanism, a transverse movement mechanism, a closing assembly mechanism, a flipping mechanism, a coding mechanism, a detection mechanism, and corresponding supporting conveying, detection, and positioning devices. Unqualified products can be eliminated, making the assembly of insulating sheets more reliable, ensuring product quality, improving production efficiency, saving human resources, and also avoiding the occurrence of manual mis-installation and omission.

[0007] The beneficial effect of the present invention is that during the production process of the motor stator installation insulating sheet, the operator only needs to place a batch of insulating sheets into the material sorting vibration plate of the feeding and sorting mechanism, and the motor stator is placed in the turnover box and input by the turnover conveyor table. The motor stator insulating sheet assembly equipment can automatically complete the insulating sheet material sorting, feeding and pre-installation rotation and transposition, and after the A-side insulating sheet is assembled and installed, the stator is flipped 180 degrees by the flipping mechanism, and then the B-side insulating sheet is installed in the stator. Finally, the stator coding and final inspection are completed, and each station is equipped with a detection mechanism and a sensor component to detect the assembly status of the insulating sheet in real time, and unqualified products are automatically rejected. The labor intensity is low, and the product quality is greatly improved. The stator assembled with double-sided insulating sheets is automatically output after passing the inspection, which is convenient for connection with the previous and next processes. The degree of automation is high, and no assembly skills are required for the operator, thereby improving production efficiency.

[0008] The intelligent assembly equipment for motor stator insulation sheets of the present invention has a reasonable overall structure and is easy to use. It automatically completes the feeding and assembly of parts with a high degree of automation and has functions such as refill notification and finished product detection, effectively improving production efficiency and production quality and reducing labor intensity and production costs.

[0009] All assembly work is completed automatically and intelligently, which greatly reduces workload, replaces manual work and improves assembly efficiency. At the same time, a fully automatic installation device is used to improve installation quality and reduce costs. An insulating sheet closing mechanism is configured to ensure that the insulating sheets are directly and effectively installed on the stator silicon steel sheets, improving product assembly quality. The assembly equipment transports the stator turnover box into the machine via a turnover conveyor table. After the stator insulating sheet is installed, it is output to the next workstation via a work tray. The entire equipment is equipped with multiple sensor components and detection mechanisms to measure the installation status of the insulating sheet. The clamping assembly position accuracy of the product is almost unaffected by the product dimensional error, which greatly improves the assembly accuracy of the product. A human-machine interface is used to control various actions of the equipment, as well as various alarm operation prompts of the equipment, with a high degree of automation.
