[0012] The present application provides a linear motor stator automatic production line 1, and a magnet mounting production line 2, which realizes the automation of the entire process from loading the magnetic plate 10 to magnet mounting, detection, and unloading by setting a loading device 20, a magnet mounting device 30, a detection device 40, and a first unloading device 50. The sheet metal cover mounting production line 6 integrates multiple processes such as loading, torque testing, wiping, dispensing, mounting, height detection, and unloading into one, forming a complete automated production line. Compared with traditional manual operation or semi-automatic production methods, it greatly reduces manual intervention, avoids inefficiency and instability in manual operation, and further improves production efficiency.

[0013] In some embodiments, reference Figures 1 to 12 The feeding device 20 includes a magnetic plate 10 transport mechanism and a magnetic plate 10 feeding mechanism. The magnetic plate 10 transport mechanism is a feeding end, including a basket 201 and a basket elevator 202. The basket 201 moves along the second direction ( Figure 2 A plurality of clamping and placing areas 203 are provided at intervals (as shown in the Z direction) for placing a plurality of magnetic plates 10. A basket elevator 202 is provided below the basket 201 for driving the basket 201 to move up and down so that any clamping and placing area 203 corresponds to the feeding mechanism of the magnetic plate 10 along the first direction.

[0014] The feeding mechanism of the magnetic plate 10 includes a material pulling module, a material taking module and a docking station 213 arranged in sequence along the first direction, the material taking module includes a support frame 204 and a negative pressure adsorption plate 205, and the support frame 204 is arranged between the material pulling module and the docking station 213 along the third direction ( Figure 2A first linear motor 206 extending in a first direction is disposed on the top of the first linear motor 206. The negative pressure adsorption plate 205 is connected to the driving end of the first linear motor 206, and is used to transfer the magnetic plate 10 between the pulling module and the docking station 213, and transfer the magnetic plate 10 to the next device through the docking station 213.

[0015] Exemplarily, the provision of the material basket 201 and the material basket elevator 202 realizes the automatic loading and transportation of the magnetic plate 10, reduces manual intervention, and ensures that the clamping placement area 203 is accurately docked with the loading mechanism of the magnetic plate 10. The material picking module adopts a negative pressure adsorption plate 205, which can realize the precise transfer of the magnetic plate 10 and avoid the displacement or damage of the magnetic plate 10 during the transfer process. The docking station 213 is a platform commonly used in the prior art to connect and transition different equipment. In this embodiment, the docking station 213 can be raised and lowered, and a carrier assembly line 701 is arranged below it. When the docking station 213 moves to the lower position, it is fixed to the carrier in the carrier assembly line 701, and the magnetic plate 10 that is adsorbed and transferred is carried by the carrier. Then the docking station 213 moves to the upper position, and the carrier with the magnetic plate 10 is sent to the assembly line 701 in the magnet sticking equipment 30 for magnet sticking operation.

[0016] In some embodiments, reference Figures 1 to 12 The material pulling module includes a first linear guide rail 207, a material picking plate 208, a buffer plate 209 and a limit plate 210. The first linear guide rail 207 and the material picking plate 208 both extend along a first direction, the material picking plate 208 is disposed at the top of the first linear guide rail 207 and connected to the driving end of the first linear guide rail 207, and is used to drive the material picking plate 208 to move relative to the basket elevator 202 along the first direction to the basket 201 through the first linear guide rail 207.

[0017] A check assembly is provided at the top of one end of the material picking plate 208 near the material basket 201, and the check assembly includes a mounting block 211, a spring assembly and an elastic downward pressure block. One end of the elastic downward pressure block is rotatably connected to the mounting block 211 along the first direction, and the other end is provided with a stop protrusion 212. The spring assembly is arranged between the stop protrusion 212 and the mounting block 211, and is used for when the check assembly moves to the clamping placement area 203, the stop protrusion 212 abuts and contracts with the top of the magnetic plate 10, and when moving out of the clamping placement area 203, the stop protrusion 212 abuts against the end of the magnetic plate 10 to push the magnetic plate 10 to move to the top of the cache plate 209.

[0018] Exemplarily, the first linear guide 207 drives the material picking plate 208 to move in the first direction, thereby realizing the automatic transfer of the magnetic plate 10 from the material basket 201 to the buffer plate 209, reducing manual operations and improving production efficiency. The check assembly can automatically adapt to the movement of the magnetic plate 10 through the cooperation of the spring assembly and the elastic pressing block, ensuring that the magnetic plate 10 is stable and free of jams during the transfer process, thereby improving the reliability of material transfer. The buffer plate 209 is provided with limit plates 210 at both ends along the third direction and at one end away from the material basket 201 along the first direction, which can fix and limit the magnetic plate 10 to ensure that the magnetic plate 10 is accurately positioned on the buffer plate 209.

The magnet sticking lifting platform 305 is erected at both ends of the magnet sticking section assembly line 303 along the third direction, and is arranged at intervals along the first direction. The top of the magnet sticking lifting platform 305 is provided with an operating area 306 corresponding to the magnetic plate 10, and a lifting block is provided at the bottom. A plurality of driving cylinders 307 are provided on both sides along the third direction, which are used for when the magnetic plate 10 is transported to the magnet sticking lifting platform 305, the plurality of driving cylinders 307 drive the lifting blocks to move upward, and push the magnetic plate 10 into the operating area 306.

[0020] The lateral displacement module 304 extends along the first direction and is arranged on one side of the magnet sticking section assembly line 303 along the third direction. The magnet sticking modules 301 are respectively arranged on both sides of the glue dispensing module 302 along the first direction, and the bottoms of the three are slidably connected to the lateral displacement module 304. A longitudinal displacement module 308 is also arranged at the connection between the magnet sticking module 301 and the glue dispensing module 302 and the lateral displacement module 304, which is used to drive the magnet sticking module 301 or the glue dispensing module 302 to move along the first direction to the magnet sticking lifting platform 305 for operation through the lateral displacement module 304 and the longitudinal displacement module 308.

[0021] For example, the two magnet sticking lifting platforms 305 drive the lifting blocks to move upward by driving the cylinders 307, and push the magnetic plate 10 into the working area 306, so as to realize the automatic positioning and fixing of the magnetic plate 10, reduce the manual operation, and improve the production efficiency. The magnet sticking module 301 and the glue dispensing module 302 realize precise movement through the lateral displacement module 304 and the longitudinal displacement module 308, and can be flexibly adjusted according to the position and demand of the magnetic plate 10 to ensure the accuracy of magnet sticking and glue dispensing.

The left material bin 311 and the right material bin 312 are respectively arranged on both sides of the feed plate 310 along the first direction, and are both hollow, for stacking a plurality of magnetic strips along the second direction.

[0023] Along the first direction, the bottom of the left material bin 311 and the left feeding groove 313, as well as the bottom of the right material bin 312 and the right feeding groove 314 are all connected. The side ejection assembly is respectively arranged on the side of the left material bin 311 and the right material bin 312 away from the feeding plate 310 along the first direction, and includes an ejection cylinder 315 and an ejection plate 316. The ejection plate 316 extends along the first direction, and one end away from the feeding plate 310 is connected to the driving end of the ejection cylinder 315, and is used to drive the ejection plate 316 along the first direction relative to the feeding plate 310 through the ejection cylinder 315 to eject the magnetic strips at the bottom of the left material bin 311 and the right material bin 312 into the left feeding groove 313 and the right feeding groove 314.

[0024] For example, the left bin 311 and the right bin 312 are respectively arranged on both sides of the feeding plate 310, and can store multiple magnetic strips at the same time. Through the cooperation of the ejection cylinder 315 and the ejection plate 316, the magnetic strips can be accurately pushed into the feeding groove, which reduces manual operation and improves feeding efficiency. Through the precise cooperation of the feeding groove and the ejection assembly, the stability of the magnetic strips during the transportation and mounting process is ensured, and quality problems caused by the deviation of the magnetic strips are avoided.

[0027] Exemplarily, the magnetic pasting head uses a combination of the first cylinder 318 and the second cylinder 321, which can achieve multi-directional precise movement, so that the magnetic pasting head can accurately place the magnetic strip to the specified position of the magnetic plate 10, improving the precision and consistency of magnetic pasting. The double blanking through holes in the material block accurately correspond to the feeding grooves of the magnetic plate 10, and the double blanking pressing plates at the bottom of the fixed block 323303 can accurately press the magnetic strip to the top of the magnetic plate 10, ensuring the precise positioning and fixation of the magnetic strip during the pasting process, avoiding quality problems caused by position deviation.
