For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] See also Figure 1 and Figure 2, shows a terminal welding and performance testing device for a motor stator provided in this embodiment, including a feed slide assembly 1, a handling robot 2, a bridge line height detection mechanism 3, a terminal welding mechanism 4, a terminal cooling mechanism 5, a laser marking mechanism 6, an EOL testing mechanism 7, a defective discharge line 8, and a discharge slide assembly 9. Among them, the feed slide assembly 1 is used to receive products and transport them to a position close to the handling robot 2; the handling robot 2 is used to transport products and transfer them between mechanisms; the bridge line height detection mechanism 3 is used to detect the bridge line height of the product and feed back the detection results to the host computer; the terminal welding mechanism 4 is used to weld terminals, and the terminal cooling mechanism 5 is used to dissipate heat from the welded product; the laser marking mechanism 6 is used to mark the product with a code; the EOL testing mechanism 7 is used to perform electrical performance testing on the product; the defective discharge line 8 is used to discharge unqualified products, and the discharge slide assembly 9 is used to discharge qualified products.

[0043] Specifically, see Figure 3 and Figure 4 The bridge line height detection mechanism 3 includes a height detection bracket 31, a height detection downward driving cylinder 32, a height detection lifting slide 33, a height detection lifting plate 34, a height detection circular pressure plate 35, a height detection movable rod 36, a height detection displacement sensor 37 and a height detection buffer spring 38.

[0044] The height detection downward pressure drive cylinder 32 is fixed to the height detection bracket 31. The piston rod of the height detection downward pressure drive cylinder 32 is fixedly connected to the slider of the height detection lifting and lowering slide 33. The height detection lifting plate 34 is fixed to the outer side of the slider of the height detection lifting and lowering slide 33. The outer side of the height detection lifting plate 34 is equipped with upper and lower mounting plates spaced vertically. The height detection downward pressure drive cylinder 32 is controlled by the host computer during operation, driving the height detection lifting plate 34 to rise or fall to the set height.

[0045] The height detection displacement sensor 37 is fixed on the upper mounting plate. The shape of the height detection circular pressure plate 35 matches the shape of the part where the product is wrapped around the bridge line. It is fixed on the bottom end of the height detection movable rod 36, and the height detection movable rod 36 is movably arranged on the lower mounting plate.

[0046] Preferably, the top of the height detection movable rod 36 is a large head end, and the diameter of the large head end is larger than the aperture of the vertical perforation on the lower mounting plate, so that the large head end will not slide off the vertical perforation. The top surface of the large head end is a plane. When the height detection circular pressure plate 35 presses against the bridge line on the product, the height detection movable rod 36 can slide upward and press against the height detection displacement sensor 37. The displacement information of the height detection displacement sensor 37 is read by the host computer and compared with the pre-stored reference range. When the displacement information of the height detection displacement sensor 37 is measured to be within the reference range, it can be determined that the height of the bridge line is within the qualified range. It is understandable that if the bridge line is missing a turn, or the winding position is too low, the height detection displacement sensor 37 may not read, or the reading may be less than the pre-stored reference range, and it can be determined to be unqualified; conversely, if the bridge line is extra turn, or the winding position is too high, the reading of the height detection displacement sensor 37 exceeds the pre-stored reference range, and it can also be determined to be unqualified.

[0047] Height detection buffer spring 38 is mounted on the outer periphery of height detection movable rod 36 and sandwiched between the lower mounting plate and the height detection circular pressure plate 35. The presence of height detection buffer spring 38 helps the height detection circular pressure plate 35 quickly return to its initial height setting after detection. Furthermore, because height detection buffer spring 38 applies a certain upward force to the height detection circular pressure plate 35, it can compress any gaps in the bridge wire, improving the accuracy of bridge wire height detection. This compacted bridge wire layout is more compact, contributing to improved product quality.

[0048] Specifically, see Figure 5 and Figure 6 The terminal welding mechanism 4 includes a welding fixture 41, a welding movable slide 42, a spot welding head 43 and a welding movable mechanism.

The welding movable mechanism can drive the spot welding head 43 to move to a position close to the product to achieve welding of the product terminals.

[0049] Furthermore, the above-mentioned welding moving mechanism includes a welding fixed bracket 44, a welding lifting drive member 45, a welding lifting slide group 46, a welding lifting plate 47 and a welding transverse driving member 48; the welding lifting driving member 45 is fixed on the welding fixed bracket 44, the power output end of the welding lifting driving member 45 is fixedly connected to the slider of the welding lifting slide group 46, the welding lifting plate 47 is fixedly connected to the slider of the welding lifting slide group 46, the welding transverse driving member 48 is fixed on the welding lifting plate 47, and the spot welding head 43 is fixedly connected to the power output end of the welding transverse driving member 48. Through the above design, the welding moving mechanism can move the spot welding head 43 to the target position in three-dimensional space.

[0050] In this embodiment, the terminal welding mechanism 4 is provided with two spot welding heads 43 that are arranged obliquely and symmetrically. The two spot welding heads 43 are used to weld the left and right connection parts of a terminal respectively.

[0052] Specifically, see Figure 7 The laser marking mechanism 6 includes a laser marking machine 61, a marking fixture 62, a marking material detection sensor 63, a marking protective cover 64, and a marking protective cover driver 65. The marking fixture 61 is used to secure the product, the marking material detection sensor 62 is used to detect whether a product is placed on the marking fixture 61, and the laser marking machine 61 is used to emit laser light at the product to form a code mark. The marking protective cover 64 is hinged to the power output end of the marking protective cover driver 65. The marking protective cover driver 65 can drive the marking protective cover 64 to swing downward to cover the product, thereby protecting the product outside the code mark area. The marking protective cover 64 has a reserved gap corresponding to the product marking area to allow laser light to enter.

[0053] Specifically, see Figure 8 and Figure 9The EOL test mechanism 7 includes a test fixture 71, a test bracket 72, a test lifting drive 73, a test lifting slide 74, a test lifting plate 75, a test fixture 76, and a test fixture opening and closing cylinder 77; the test fixture 71 is used to fix the product, the test lifting drive 73 is fixed on the test bracket 72, the power output end of the test lifting drive 73 is fixedly connected to the slider of the test lifting slide 74, the test lifting plate 75 is fixedly connected to the slider of the test lifting slide 74, and the test lifting drive 73 is controlled by the host computer when working, which can make the test lifting plate 75 drop to the set height. The test fixture opening and closing cylinder 77 is installed at the bottom of the test lifting plate 75, and the two clamping claws of the test fixture 76 are respectively fixedly connected to the two piston rods of the test fixture opening and closing cylinder 77. The test fixture opening and closing cylinder 77 can drive the test fixture to clamp the terminal contact on the product to achieve electrical connection. After the host computer collects the feedback electrical signal, it can analyze the electrical performance of the product.

[0055] The product is placed on the fixed fixture of the feed slide assembly 1. The positioning of the product is completed through the positioning notch on the fixed fixture.
