Description

Technical Field

[0001] This invention relates to the field of automated motor assembly equipment, and in particular to a terminal insertion device and its insertion method. Background Technology

[0002] During motor assembly, terminals need to be inserted into the stator. Stators come in various models; one model has a protruding outer wall forming terminal slots for insertion, while another model has terminals located on the upper side wall. Existing terminal insertion equipment and methods typically use two separate devices for different stator models, resulting in high production costs and large equipment footprints. A single device cannot be used for terminal insertion of two different stator models. Furthermore, existing terminal insertion equipment suffers from low insertion accuracy. Therefore, there is an urgent need to develop a terminal insertion device and method to meet practical application needs. Summary of the Invention

The dust cover can be lowered to cover the stator. The air blowing pipe blows air onto the stator, and the air suction plate sucks in the air to draw out the dust inside the stator.

[0071] The lifting cylinder 71 drives the dust cover to descend and cover the stator. The descent of the dust cover causes the air blowing pipe and the air suction plate to descend simultaneously. The air blowing pipe blows up the dust, and the air suction plate sucks up the dust, thus cleaning the inside of the stator.

[0072] The insertion method applied to a terminal insertion device is as follows:

[0073] The turntable mechanism drives the stator to move. If it is the first model stator, the first pre-installation mechanism is used to pre-insert the terminals into the stator. If it is the second model stator, the second pre-installation mechanism is used to pre-insert the terminals into the stator. After pre-installation, the turntable mechanism drives the stator to move to the side of the insertion mechanism, and the insertion mechanism securely inserts the terminals into the stator. The turntable mechanism drives the stator to move to the side of the cutting mechanism, and the cutting mechanism cuts the winding wire ends on the outer wall of the stator. The turntable mechanism drives the stator to move to the side of the dust removal mechanism. The dust removal mechanism removes dust from the inside of the stator, and the turntable mechanism drives the stator to move for material discharge.

[0074] The key design feature of this invention is that it automates the movement, pre-pressing, fastening, wire end trimming, and dust removal of the stator by employing a turntable mechanism, a first pre-assembly mechanism, a second pre-assembly mechanism, an insertion mechanism, a cutting mechanism, and a dust removal mechanism. This improves assembly efficiency and reduces the defect rate. The equipment is applicable to two different stator models, offering a wide range of applications and reducing production costs. The use of a longitudinal drive device and a downward drive device satisfies the positional movement requirements during terminal pre-pressing. A material-pushing device moves the terminals in the terminal strip forward to obtain individual terminals after punching, meeting pressing requirements and improving work efficiency. The force-bearing components are suitable for both stator models, offering a wide range of applications and reducing production costs.

[0075] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
