[0034] The technical solution of this embodiment of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiment is one embodiment of the present invention, and not all embodiments thereof. Based on this embodiment 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.

[0035] Please see Figures 1 to 7 An embodiment of this utility model provides a stator assembly paint stripping device, which includes:

[0036] Paint stripping positioning mechanism 1 includes a positioning platform 11, on which a rotating fixture 13 for placing a stator assembly 3 is mounted. A rotation drive module 12 is mounted at one end of the rotating fixture 13, a positioning block 14 is mounted on one side of the rotating fixture 13, and a push block assembly 15 that can be inserted into the rotating fixture 13 and cooperates with the positioning block 14 is mounted on the other side. A wire end positioning assembly 16 for positioning the lead wire end of the stator assembly 3 is mounted on one side of the rotating fixture 13.

[0037] The paint stripping mechanism 2 is installed on one side of the paint stripping positioning mechanism 1. It includes a first linear drive module 21, a second linear drive module 22 installed on the first linear drive module 21, and a paint stripping machine 23 installed on the second linear drive module 22.

[0038] The paint stripping machine 23 is existing technology. The structure and function of the paint stripping machine 23 is to clamp and rotate the rubber coating layer at the lead wire end of the stator assembly 3.

[0039] The rotating fixture 13 has clearance grooves 131 on both sides for the mechanical gripper to grasp the stator assembly 3 and place it onto the rotating fixture 13. The mechanical gripper is existing technology. For example, the mechanical gripper can be two cylinder grippers. The two cylinder grippers are used to grip the stator assembly 3 and extend into the clearance grooves 131 to place the stator assembly 3 onto the rotating fixture 13.

[0040] The rotating fixture 13 is equipped with a positioning block 132 for laterally positioning the stator assembly 3 within the fixture cavity of the rotating fixture 13. One end of the stator assembly 3 is connected together by several stators, while the other end has several stators that are not connected. Therefore, grooves are formed between the stators on the end faces where the stators are not connected. The positioning block 132 is inserted into the grooves to achieve lateral positioning of the stator assembly 3 on the rotating fixture 13, thereby preventing the stator assembly 3 from sliding laterally inside the rotating fixture 13.

[0041] The rotation drive module 12 is a rotary cylinder or a rotary motor.

[0042] The number of positioning blocks 14 is set to a certain number, and the number of positioning blocks 14 are linearly arranged on the front side of the rotating fixture 13. The number of push block assemblies 15 is set to a certain number, and the number of push block assemblies 15 are linearly arranged on the rear side of the rotating fixture 13. The number of positioning blocks 14 and the number of push block assemblies 15 correspond one-to-one. The bottom of the rotating fixture 13 has a certain number of insertion openings 133, and the number of insertion openings 133 correspond one-to-one with the number of push block assemblies 15. The insertion openings 133 are used to allow the push block assemblies 15 to be inserted into the rotating fixture 13.

[0043] The pusher assembly 15 includes a pusher cylinder 151 and a pusher 152 mounted on the pusher cylinder 151.

[0044] The line end positioning component 16 includes an upper clamping positioning component 161 mounted on the positioning platform 11 and a lower clamping positioning component 162 disposed vertically opposite to the upper clamping positioning component 161.

[0045] The upper clamping positioning assembly 161 includes an upper lifting cylinder 1611, an upper mounting plate 1612 mounted on the bottom of the upper lifting cylinder 1611, and several upper clamping blocks 1613 arranged linearly and mounted on the bottom of the upper mounting plate 1612. The lower clamping positioning assembly 162 includes a lower lifting cylinder 1621, a lower mounting plate 1622 mounted on the top of the lower lifting cylinder 1621, and several lower clamping blocks 1623 arranged linearly and mounted on the top of the lower mounting plate 1622. The several upper clamping blocks 1613 and the several lower clamping blocks 1623 correspond one-to-one. The upper clamping blocks 1613 and the lower clamping blocks 1623 are used together to position the wire end of the stator assembly 3.

[0046] The bottom of the upper clamping block 1613 is inverted V-shaped, and the top of the lower clamping block 1623 is V-shaped.

[0047] A separating post 17 is also installed on one side of the rotating fixture 13. The separating post 17 is pointed, with a first smooth inclined surface 171 at one end and a second smooth inclined surface 172 at the other end. The reason for setting the separating post 17 is that sometimes, two lead wires of the stator assembly 3 may be adjacent to each other. In this case, assuming that one lead wire is the current stripped wire and the other lead wire is the next stripped wire or has already been stripped, when the rotating fixture 13 rotates 90 degrees, these two lead wires will be separated by the separating post 17, and when... The first stripped wire end slides along the first smooth inclined surface 171 and falls into one side of the separator post 17. The next stripped wire end or the already stripped wire end slides along the second smooth inclined surface 172 and falls into the other side of the separator post 17. The front position of one side of the separator post 17 corresponds to the center position between the upper clamping block 1613 and the lower clamping block 1623, while the front position of the other side of the separator post 17 is far away from the center position between the upper clamping block 1613 and the lower clamping block 1623. Therefore, the separator post 17 can effectively separate two adjacent lead wire ends and ensure that the stripping of the current stripped wire end is not affected by the other one.

[0048] In this embodiment, the first linear drive module 21 and the second linear drive module 22 are slide table modules. In other embodiments, the first linear drive module 21 and the second linear drive module 22 are cylinders or a combination of cylinders and slide rails (or guide rods and bushings), or a combination of rotary motors, synchronous pulleys and synchronous belts, and slide rails, or a combination of rotary motors, lead screws, and slide rails, or other drive components that are driven in a linear manner.

[0049] The linear driving direction of the first linear drive module 21 is orthogonal to the linear driving direction of the second linear drive module 22. For example, if the linear driving direction of the first linear drive module 21 is the y-axis direction, then the linear driving direction of the second linear drive module 22 is the x-axis direction.

[0050] An embodiment of the present invention provides a stator assembly paint stripping device, the working principle of which is as follows:

[0051] S1: In the initial state, the rotating fixture 13 is set vertically. When the mechanical gripper of the prior art puts the stator assembly 3 into the rotating fixture 13, the positioning block 132 positions the stator assembly 3 in the lateral direction.

[0052] S2: Rotation drive module 12 drives rotation fixture 13 to rotate 90 degrees, changing the vertically set rotation fixture 13 to a horizontally set position;

[0053] S3: The push cylinder 151 of the push block assembly 15 drives the push block 152 to move forward and inserts the push block 152 into the insertion opening 133, so that the push block 152 enters the rotating fixture 13 and pushes the stator assembly 3 to abut against the positioning block 14, so that the push block assembly 15 and the positioning block 14 together achieve the front-back positioning of the stator assembly 3.

[0054] S4: The upper clamping positioning component 161 and the lower clamping positioning component 162 of the wire end positioning component 16 work together. The upper lifting cylinder 1611 of the upper clamping positioning component 161 drives the upper clamping block 1613 on the upper mounting plate 1612 to move downward, and the lower lifting cylinder 1621 of the lower clamping positioning component 162 drives the lower clamping block 1623 on the lower mounting plate 1622 to move upward, so that the inverted V-shaped opening of the upper clamping block 1613 and the V-shaped opening of the lower clamping block 1623 together clamp and position the wire end of the skewed stator component 3.

[0055] S5: Because the linear driving direction of the first linear drive module 21 is orthogonal to the linear driving direction of the second linear drive module 22, therefore, in this embodiment,

[0056] The first linear drive module 21 is configured as a front-to-back drive module, and the second linear drive module 22 is configured as a lateral drive module. The function of the second linear drive module 22 is to drive the paint stripper 23 to sequentially align with the positions between the inverted V-shaped openings of several upper clamping blocks 1613 and the V-shaped openings of lower clamping blocks 1623. The function of the first linear drive module 21 is to drive the paint stripper 23 to fit onto the lead wire ends of the stator assembly 3 and strip the paint from them. The specific process is as follows:

[0057] S51: The second linear drive module 22 drives the paint stripper 23 to align with the center position between the inverted V-shaped opening of the upper clamping block 1613 and the V-shaped opening of the lower clamping block 1623 of the first.

[0058] S52: The first linear drive module 21 drives the paint stripper 23 (including driving the second linear drive module 22) forward to align and fit into the lead wire end position of the stator assembly 3.

[0059] S53: The upper clamping positioning component 161 of the wire end positioning component 16 resets upward and the lower clamping positioning component 162 resets downward, thereby causing the wire end positioning component 16 to release the wire end position of the stator component 3.

[0060] S54: The first linear drive module 21 continues to drive the paint stripper 23 forward to align and fully insert it into the lead wire end of the stator assembly 3;

[0061] S55: The paint stripper 23 clamps the coating layer of the lead wire end of the stator assembly 3, and the paint stripper 23 rotates, and the first linear drive module 21 drives the paint stripper 23 to exit backward, thereby completing the paint stripping of the paint stripper 23.

[0062] S56: Then, the lead wires of the next stator assembly 3 are stripped of their enamel coating in sequence. The stripping principle is the same as that of S51-S55, until all the lead wires of the stator assembly 3 are stripped.

[0063] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
