[0002] Stator wire binding machines are divided into single-sided stator wire binding machines and double-sided stator wire binding machines. They are suitable for the production of motors for household, industrial and agricultural use. In the process of binding the motor stators, automatic loading devices are often used to load and unload the motor stators that need to be bound.

[0003] When the automatic feeding device of the wire binding machine in the prior art is used, the structure of most automatic feeding devices is relatively fixed, and the fixture and other structures cannot be automatically replaced, which makes it inconvenient for the device to automatically feed stators of different models, and workers need to spend more time to switch the fixture of the feeding device, which makes the application range of the device relatively low.

[0039] The switching mechanism 2 includes a disassembly unit 21 , which is located inside the placement table 13 . The disassembly unit 21 is used to disassemble and replace the tray on which the stator is placed.

[0040] As a further limitation of the present invention, the disassembly unit 21 includes four first material trays 2101, each of which is clamped inside the placement table 13, and two connecting blocks 2102 are fixedly installed on the outer surface of each first material tray 2101. A connecting bearing 2103 is fixedly installed on the inner wall of each first material tray 2101, and the upper surface of each connecting bearing 2103 is rotatably connected to a rotating cylinder 2104, and a connecting disk 2105 is fixedly installed on the bottom surface of each rotating cylinder 2104. Each connecting column 16 is clamped inside the connecting disk 2105, so that the rotating motor 15 cooperates with the connecting column 16 to drive the connecting disk 2105 to rotate, thereby driving the rotating cylinder 210 4 is rotated, so as to facilitate the wire binding process of the stator inside the rotating cylinder 2104. The inner wall of each rotating cylinder 2104 is fixedly installed with an anti-slip sleeve 2106. Four groups of placement grooves 2107 are opened inside the placement table 13, and the number of each group of placement grooves 2107 is two. Each connecting block 2102 is clamped inside the placement groove 2107. Two connecting springs 2108 are fixedly installed on the inner top wall of each placement groove 2107. A first wedge block 2109 is fixedly installed on the bottom end of each group of connecting springs 2108. A connecting rod 2110 is fixedly installed on the upper surface of each first wedge block 2109. The top of each connecting rod 2110 passes through the placement table 13. On the outside, a fixing spring 2111 is fixedly installed on the inner wall of each placement groove 2107, and a sliding block 2112 is fixedly installed on the end of each fixing spring 2111 close to the first material tray 2101, and each sliding block 2112 is clamped in the interior of the connecting block 2102, and the outer surface of each sliding block 2112 is slidably connected with the outer surface of the first wedge block 2109, so that when the first wedge block 2109 moves downward, it can push the sliding block 2112 away from the connecting block 2102, and a fixing table 2113 is arranged on the right side of the placement table 13, and a rotating motor 2114 is fixedly installed on the upper surface of the fixing table 2113, and a rotating table 2 is fixedly installed on the output end of the rotating motor 2114. 115, a support rod 2116 is fixedly mounted on the upper surface of the rotating table 2115, a cylinder 2117 is fixedly mounted on the inner top wall of the support rod 2116, a connecting plate 2118 is fixedly mounted on the telescopic end of the cylinder 2117, an electromagnet 2119 is fixedly mounted on the bottom surface of the connecting plate 2118, and two extrusion columns 2120 are fixedly mounted on the bottom surface of the connecting plate 2118. By providing a disassembly unit 21, when different types of stators need to be loaded, the device can automatically disassemble and install the material tray conveniently, and there is no need for workers to manually disassemble and install, which reduces the time for disassembly and installation of the material tray, thereby increasing the efficiency of disassembly and installation of the material tray, and at the same time increases the scope of application of the device.

[0041] See also Figure 5A telescopic column 2121 is fixedly installed on the upper surface of each first wedge block 2109, and the telescopic end of each telescopic column 2121 is fixedly connected to the inner top wall of the placement groove 2107. The installation of the telescopic column 2121 serves to limit the moving trajectory of the first wedge block 2109, thereby preventing the first wedge block 2109 from deviating from the moving trajectory during movement, thereby ensuring the stability of the movement of the first wedge block 2109.

[0042] See also Figure 3 and Figure 5 A slider 2122 is fixedly installed on the bottom surface of each sliding block 2112, and a sliding groove 2123 is opened on the inner bottom wall of each placement groove 2107. Each slider 2122 is slidably connected inside the sliding groove 2123. The shape of the slider 2122 is T-shaped, and the shape of the sliding groove 2123 matches the shape of the slider 2122. The installation of the slider 2122 and the sliding groove 2123 plays a role in limiting the moving trajectory of the sliding block 2112, thereby ensuring the stability of the movement of the sliding block 2112.

[0043] See also Figure 7 The upper surface of the fixed table 2113 is rotatably connected with a fixed bearing 2124, and the upper surface of the fixed bearing 2124 is rotatably connected to the bottom surface of the rotating table 2115.

[0044] The specific implementation of this embodiment is as follows: when the first material tray 2101 needs to be switched, the power provided by the cylinder 2117 is used to drive the connecting plate 2118 to move downward, so that the connecting plate 2118 drives the electromagnet 2119 and the squeezing column 2120 to move downward, and when the squeezing column 2120 contacts the connecting rod 2110 and continues to move downward, the connecting rod 2110 drives the first wedge block 2109 to move downward, so that the first wedge block 2109 pushes the sliding block 2112 to move to the side away from the first material tray 2101, and then the sliding block 2112 slides away from the connecting block 2102. When the sliding block 2112 completely leaves the inside of the connecting block 2102 and is a certain distance away from the connecting block 2102, the bottom surface of the electromagnet 2119 contacts the upper surface of the first material tray 2101. At this time, the magnetism provided by the electromagnet 2119 is used to adsorb the first material tray 2101 on the electromagnet. The first tray 2101 is moved upward by the power provided by the cylinder 2117 in cooperation with the connecting plate 2118 and the electromagnet 2119, and then the power provided by the rotating motor 2114 is used to drive the rotating table 2115 to rotate ninety degrees clockwise, and the first tray 2101 is placed on the adjusting unit 22, thereby replacing the first tray 2101. When the replacement is completed, the rotating motor 2114 is used to rotate in the opposite direction, and the power provided by the cylinder 2117 is used to place the replaced tray at the position of the first tray 2101, and the electromagnet 2119 is disconnected. Then, the connecting plate 2118 is moved away from the placing table 13, so that the sliding block 2112 is clamped inside the connecting block 2102 under the action of the elastic force of the fixed spring 2111, thereby completing the replacement of the first tray 2101, and no manual replacement by workers is required, thereby increasing the replacement efficiency of the first tray 2101.

[0045] Example 2: Please refer to Figure 6 , Figure 8 and Fig. 9 The present invention provides a technical solution: an automatic feeding device for a wire binding machine. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0046] The switching mechanism 2 further includes an adjusting unit 22 , which is located on the right side of the placement table 13 . The disassembly unit 21 is used in conjunction with the adjusting unit 22 , and the adjusting unit 22 is used to replace and adjust the position of the replaced material tray.

A connecting frame 2212 is fixedly installed on the left side, and the outer surface of the connecting frame 2212 is slidably connected to the inner wall of the limit seat 2210. When the two servo motors 2203 drive the two worms 2202 to rotate in the same direction, the worms 2202 cooperate with the turbine 2207 to drive the moving platform 2205 to move left and right. When the two servo motors 2203 drive the two worms 2202 to rotate in different directions, the rack plate 2211 moves forward and backward. The upper surface of the rack plate 2211 and the upper surface of the connecting frame 2212 are jointly fixedly installed with a moving frame 2213. Four second material trays 221 are arranged above the moving frame 2213. 4.

However, the inner diameters of the rotating cylinder 2104 and the anti-slip sleeve 2106 are different from those of the interior of the first material tray 2101. By providing an adjustment unit 22, the device automatically changes the position of the second material tray 2214, thereby facilitating the device to exchange the material tray that needs to be replaced, thereby avoiding workers manually changing the position of the material tray, and further increasing the efficiency of replacing the material tray.

A universal wheel 2216 is fixedly installed on the bottom surface of each supporting leg 2215. The installation of the supporting legs 2215 and the universal wheel 2216 plays a role in supporting the mobile frame 2213, thereby preventing the mobile frame 2213 from tilting, and further ensuring the stability of the movement of the mobile frame 2213.

[0049] The specific implementation of this embodiment is as follows: when the disassembly unit 21 moves the first material tray 2101 to the mobile frame 2213, the power of the electromagnet 2119 is disconnected, so that the first material tray 2101 is placed on the mobile frame 2213, and then the power provided by the servo motor 2203 is used to drive the two worms 2202 to rotate in the same direction, so that the worm 2202 drives the turbine 2207 to move left and right, and then the turbine 2207 cooperates with the rotating shaft 2206 to drive the mobile platform 2205 to move left and right, and then the power provided by the servo motor 2203 is used to drive the two worms 2202 to rotate in opposite directions, so that the two worms 2202 drive the turbine 22 07 rotates, thereby causing the turbine 2207 to drive the rotating shaft 2206 to rotate, and at the same time, the rotating shaft 2206 drives the connecting gear 2208 to rotate, so that the connecting gear 2208 drives the rack plate 2211 to move back and forth, and then the rack plate 2211 cooperates with the connecting frame 2212 to drive the moving frame 2213 to move back and forth, so that the second material tray 2214 that needs to be replaced is moved to the bottom of the connecting plate 2118, and then the second material tray 2214 is adsorbed on the electromagnet 2119 by utilizing the magnetism provided by the electromagnet 2119, and then the second material tray 2214 is installed on the placement table 13, thereby realizing the purpose of automatic replacement of the material tray.

[0055] The specific implementation of this embodiment is as follows: when the device is used to load the stator, the power provided by the hydraulic rod 305 is first used to drive the connection box 306 to move downward, so that the mounting column 308 extends into the interior of the stator, and then the power provided by the electric push rod 309 is used to drive the clamping plate 310 to move to the side away from each other, so as to clamp and fix the stator, and then the power provided by the hydraulic rod 305 is used to drive the connection box 306 to move upward, and then the power provided by the stepping motor 303 is used to drive the ball screw 302 to rotate, so that the ball screw 302 drives the T-block 304 to move, and then the stator is moved. To the top of the first material tray 2101, and then use the power provided by the hydraulic rod 305 to drive the stator to be clamped in the anti-slip sleeve 2106, and then use the power provided by the electric push rod 309 to release the clamping fixation of the stator by the clamping plate 310, and then use the power provided by the hydraulic rod 305 and the stepper motor 303 to move the T-block 304 to its original position, and then rotate the placement table 13 to move the stator to the bottom of the wire binding machine body 11, and cooperate with the rotating motor 15 to bind the stator. When the tooling body 319 is replaced, first use the power provided by the stepper motor 303 to cooperate with the ball screw 302 to drive the T-block 304 to move to The second wedge block 317 is used to push the moving rod 312, so that the moving rod 312 is aligned with the position of the second wedge block 317, and then the power provided by the hydraulic rod 305 is used to drive the connecting box 306 to move downward, so that the clamping plate 310 is clamped in the inside of the connecting ring 318, and the power provided by the electric push rod 309 is used to drive the clamping plate 310 and the inner wall of the connecting ring 318 to contact each other, and at the same time, the second wedge block 317 pushes the moving rod 312, so that the moving rod 312 slides away from the fixed column 307 for a distance, thereby releasing the fixation of the fixed column 307, and then the power provided by the hydraulic rod 305 is used to drive the connecting box 306 to move upward, so that the fixed column 307 is fixed. The fixed column 307 and other structures stay inside the L-shaped table 316, and then the connection box 306 is moved above the tooling body 319 that needs to be replaced, and the power provided by the hydraulic rod 305 is used to clamp the tooling body 319 inside the connection box 306, and make the corresponding contact pieces 315 contact each other. At the same time, in the process of the connection box 306 moving downward, the moving rod 312 cooperates with the elastic force of the limit spring 311, so that the moving rod 312 is clamped inside the tooling body 319, thereby limiting and fixing the tooling body 319, thereby achieving the purpose of replacing the tooling body 319, so that the device can be suitable for different stator loading.
