Detailed Implementation

[0018] The present invention is as follows Figure 1 As shown in Figure 7, a stator terminal insertion device includes an insertion mechanism 10 for inserting terminals into the stator, a wire end cutting mechanism 20 for cutting wire ends from the stator, a detection mechanism 30 for detecting the stator, and a transfer mechanism 40 for transferring the stator. The insertion mechanism 10, the wire end cutting mechanism 20, and the detection mechanism 30 are distributed sequentially along the transfer direction of the transfer mechanism 40. The insertion mechanism 10 includes a transfer assembly 11 for transferring the stator and a pressing assembly 12 for pressing the terminals into the stator. The output end of the pressing assembly 12 can movably press the terminals into the stator.

[0019] The transfer mechanism 40 is a robotic arm driven by a motor. This motor-driven robotic arm can sequentially pick up the stator from the insertion mechanism 10 and transfer it to the wire cutting mechanism 20, and then to the inspection mechanism 30, following a preset transfer path. This achieves fully automated, high-precision transfer of the stator between various processing stations. The robotic arm features flexible movement, precise positioning, and rapid response, effectively shortening the stator handling time between processes and avoiding collisions and positioning errors that may occur during manual handling. This ensures continuous and efficient operation of the entire production line, while also improving the overall automation level and production cycle time of the equipment.

[0020] The press-fit assembly 12 includes a mounting base 121, a material transfer device 122 for moving the terminal strip, a terminal cutting device 123 for cutting the terminal strip to obtain individual terminals, and a pressing device 124 for pressing the individual terminals into the stator. The material transfer device 122, the terminal cutting device 123, and the pressing device 124 are all disposed on the mounting base 121. The terminal cutting device 123 corresponds to the end of the terminal strip, and the output end of the pressing device 124 is located above the stator.

[0021] The mounting base 121 has a material groove 1211 for the terminal strip to pass through; the material transfer device 122 includes a material transfer drive cylinder and a material transfer plate. The material transfer plate is installed at the output end of the material transfer drive cylinder. The movement of the material transfer plate drives the terminal strip to move in the material groove 1211.

[0022] The terminal cutting device 123 includes a terminal cutting drive cylinder 1231 and a cutter 1232. The terminal cutting drive cylinder 1231 is disposed on the mounting base 121, and the cutter 1232 is mounted on the output end of the terminal cutting drive cylinder 1231. The cutter 1232 corresponds to the end of the terminal strip.

[0023] The pressing device 124 includes an electric cylinder 1241 and a pressing rod 1242. The electric cylinder 1241 is mounted on the mounting base 121. The pressing rod 1242 is mounted on the output end of the electric cylinder 1241 and can be lowered to press a single terminal into the stator.

[0024] The mounting base 121 has a vertically opening 1212 for guiding the pressure rod 1242, which can be vertically moved to the opening position.

[0025] The transfer assembly 11 includes a transverse drive device 111 and a rotary drive device 112 for driving the stator to rotate. The rotary drive device 112 is mounted at the output end of the transverse drive device 111 and is located below the clamping device 124.

[0026] The pressing assembly 12 also includes a longitudinal drive device 125 and a lifting drive device 126. The pressing drive device is installed at the output end of the longitudinal drive device 125, and the pressing device 124 is installed at the output end of the lifting drive device 126. The longitudinal drive device 125, the lifting drive device 126 and the transverse drive device 111 all adopt a drive motor, a lead screw and a sliding seat. The lead screw is installed at the output end of the drive motor and rotates with the sliding seat.

[0027] The insertion mechanism 10, through the coordinated operation of the transfer assembly 11 and the pressing assembly 12, can achieve automatic transfer, rotational alignment, and precise pressing of the stator and terminals. Specifically, the transverse drive device 111 and the rotary drive device 112 in the transfer assembly 11 can flexibly adjust the stator to the optimal pressing position. Together with the material transfer device 122, the terminal cutting device 123, and the pressing device 124 in the pressing assembly 12, they sequentially complete the step-by-step feeding of the terminal strip, the precise cutting of individual terminals, and the vertical and stable pressing of the pressing rod 1242 along the guide opening 1212. The entire insertion process is fully automated, which not only improves insertion efficiency but also ensures the consistency and accuracy of the terminal and stator insertion positions, effectively reducing deviations caused by manual operation.

[0028] The wire end cutting mechanism 20 includes a rotation drive assembly 21 for driving the stator to rotate and a wire cutting assembly 22 for cutting the wire end. The wire cutting assembly 22 is located above the rotation drive assembly 21. The wire cutting assembly 22 includes a pressing drive cylinder 221, a mounting plate 222, a protective cover 223, and a wire cutting blade 224. The mounting plate 222 is located at the output end of the pressing drive cylinder 221. The protective cover 223 is elastically floating below the mounting plate 222. The wire cutting blade 224 is located on the lower side of the mounting plate 222. The protective cover 223 has a guide groove 2231 for guiding the wire cutting blade 224. The wire cutting blade 224 corresponds to the stator in the rotation drive assembly 21.

[0029] The wire end cutting mechanism 20 uses a rotation drive assembly 21 to drive the stator to rotate. Combined with the upper cutting assembly 22, it can flexibly adjust the cutting angle of the stator to achieve targeted processing of wire ends in different positions. In the cutting assembly 22, a protective cover 223 is elastically and floatingly positioned below the mounting plate 222. When the cutting blade 224 is pressed down, the protective cover 223 first contacts the stator and then floats to adapt, both isolating and protecting the cutting area to prevent waste from splashing, and precisely guiding the cutting blade 224 along a set trajectory via its internal guide groove 2231. This significantly improves the cross-sectional quality and safety of the wire end cutting, preventing damage to the stator windings.

[0030] The testing mechanism 30 includes a rotating component 31 for driving the stator to rotate and a photographing component 32 for taking pictures of the stator, the photographing component 32 being oriented toward the stator on the rotating component 31.

[0031] The rotary drive assembly 21, rotary drive device 112, and rotary assembly 31 all include a rotary drive motor and a rotary seat for placing the stator, which is mounted on the output end of the rotary drive motor.

[0032] The imaging component 32 includes a horizontal drive device 321, a vertical drive device 322, a vertical drive device 323, and a CCD camera 324. The vertical drive device 322 is mounted at the output end of the horizontal drive device 321, the vertical drive device 323 is mounted at the output end of the vertical drive device 322, and the CCD camera 324 is mounted at the output end of the vertical drive device 323. The CCD camera 324 is movably oriented towards the stator.

[0033] The inspection unit 30 drives the processed stator to rotate via the rotating component 31, enabling the imaging component 32 to acquire image information of the stator from different angles. The CCD camera 324 in the imaging component 32 can flexibly move to the optimal shooting position under the coordinated drive of the horizontal, vertical, and longitudinal drive devices 323, achieving high-definition, all-around inspection of terminal insertion status and wire end cutting effects. This automated visual inspection method can quickly and accurately identify defects such as insertion misalignment, missing terminals, or poor cutting, promptly removing unqualified products and effectively ensuring the quality stability of the products leaving the factory.

[0034] A method for inserting the stator terminal block device includes the following steps: First, the transfer mechanism transfers the stator to the insertion mechanism; Second, the transfer assembly of the insertion mechanism transfers the stator to the side of the pressing assembly, and the output end of the pressing assembly inserts the terminals into the stator; Third, the transfer mechanism transfers the stator from the insertion mechanism to the wire end cutting mechanism; Fourth, the thread cutting mechanism cuts the thread ends on the stator; Fifth, the transfer mechanism transfers the stator from the wire end cutting mechanism to the testing mechanism; Sixth, the testing agency will test whether the stator after insertion is a qualified product.

[0035] The key design feature of this invention lies in its fully automated operation of stator terminal insertion, wire end cutting, and inspection. This is achieved by sequentially distributing the insertion mechanism, wire end cutting mechanism, and inspection mechanism along the transfer direction of the transfer mechanism, and utilizing the transfer mechanism to automatically transfer the stator between each station. This significantly improves production efficiency and reduces labor costs. Simultaneously, the cooperation between the transfer and pressing components in the insertion mechanism ensures precise stator positioning and accurate terminal pressing, guaranteeing the quality and consistency of terminal insertion. The wire end cutting mechanism allows for flexible adjustment of the stator's cutting angle, enabling targeted processing of wire ends in different orientations. Furthermore, the automatic inspection of the inserted stator by the inspection mechanism promptly removes defective products, effectively ensuring the quality of the finished products.
