Referring to fig. 6, the shell feeding device 310 automatically feeds the shell 201 through the vibration tray 311, and since the discharging direction of the vibration tray 311 forms an included angle of 90 ° with the installation direction of the installation groove 381 on the positioning fixture 380, the shell 201 conveyed by the vibration tray 311 needs to be rotated 90 ° first and then placed on the positioning fixture 380. The shell feeding device 310 comprises a shell receiving frame 312 and clamping jaws 313, wherein a plurality of material receiving grooves are distributed on the shell receiving frame 312, the number and the interval of the material receiving grooves correspond to those of the placement grooves 381, and the clamping jaws 313 and the material receiving grooves are arranged in a one-to-one correspondence manner.

In this embodiment, 4 cases 201 can be transferred to the positioning jig 380 at a time.

With continued reference to fig. 6, after the housing 201 is placed on the positioning fixture 380, the sealing ring 202 is then assembled in the slot 201b of the housing 201. The seal ring feeding device 320 automatically feeds the seal ring 202 through the vibration disc 321, and the seal ring 202 is rectangular, so the seal ring 202 conveyed by the vibration disc 321 needs to be rotated by 90 degrees and then clamped into the shell 201. The gasket feeding device 320 comprises a bracket 322, an upper plug connector 323 and a lower plug connector 324, wherein a plurality of material receiving grooves are arranged on the bracket 322, and the number and the interval between the material receiving grooves, the upper plug connector 323 and the lower plug connector 324 correspond to the number and the interval between the placement grooves 381. The bracket 322 is driven by a material receiving driving mechanism 325 connected thereto to reciprocate linearly in the X-axis direction and the Y-axis direction, and sequentially receives the seal ring 202 from the discharge port of the vibration plate 321 and transfers the seal ring to the lower side of the upper plug 323. The upper plug 323 is linearly moved and rotated in the Z-axis direction by a steering drive mechanism 326 connected thereto, so that the seal ring 202 is taken out of the bracket 322 and then rotated by 90 ° and placed on the lower plug 324. The lower plug 324 is driven by the transfer driving mechanism 327 connected thereto to reciprocate linearly in the Y-axis direction and the Z-axis direction between the upper plug 323 and the positioning jig 380, thereby pushing the seal ring 202 into the cavity 201b of the housing 201 from below. Further, after the assembly is completed, the seal ring feeding device 320 also detects whether the seal rings 202 are assembled on the housing 201 one by one from below by the industrial camera 328 arranged at the edge of the seal ring feeding device, and feeds back the detection information to the control system.

Referring to fig. 7, the glue injection device 330 is used for injecting glue into the slot 201 a. Because the time required for heating and glue pumping before glue injection is relatively long, in order to balance the production line, the number of the glue injection devices 330 can be two, and the two glue injection devices 330 are sequentially arranged along the conveying direction of the endless conveyor 370, so that the glue injection operation is alternately completed. The glue injection device 330 specifically includes a plurality of glue injection nozzles 331, a glue supply mechanism 332 disposed above the glue injection nozzles 331 for supplying glue, a protection plate 333 and a lifting plate 334 disposed below the glue injection nozzles 331, and the protection plate 333 and the lifting plate 334 are respectively located at upper and lower sides of the positioning fixture 380. The glue injection nozzles 331 are also arranged in one-to-one correspondence with the placement grooves 381. The protection plate 333 can move linearly up and down under the driving of the driving mechanism 335 connected with the protection plate, so as to avoid backwards during glue injection so as to inject glue, and move forwards during glue injection so as to prevent residual glue from dropping to pollute the table top. The lifting plate 334 can be driven by the driving mechanism 336 connected with the lifting plate to move up and down linearly, so that the plugging plate 384 of the positioning jig 380 is lifted upwards to be close to the glue injection nozzle 331 so as to inject glue, and after the glue injection is completed, the lifting plate 334 moves reversely, so that the plugging plate 384 falls back to the mounting plate 382.

Referring to fig. 8, after glue is injected, the glue amount detection device 390 starts to detect the glue injection amount, and the glue amount detection device 390 includes a height finder 3901 and a driving mechanism 3902 for driving the height finder 3901 to move linearly along the conveying direction of the endless conveyor 370, detects the glue injection amounts of the 4 shells 201 on the positioning jig 380 one by one through the movement of the height finder 3901, and feeds back the detection information to the control system.

Referring to fig. 9, after glue injection detection, the magnetic core feeding device 340 assembles the magnetic cores 203 into the corresponding shells 201 in groups of 4. The core loading device 340 includes a core feeding mechanism 341 and a core buffering mechanism 342 that are parallel and spaced apart from each other, and a core assembling mechanism 343 that is disposed above the core feeding mechanism 341 and can reciprocate between the core feeding mechanism and the core buffering mechanism, the core feeding mechanism 341 transfers the cores 203 to the bottom of the core assembling mechanism 343 in 4 groups by using carriers 3411 disposed on the linear guide, the core assembling mechanism 343 can drive the 4 material taking clamping jaws 3431 connected to the output end of the core feeding mechanism to move linearly along the Z-axis and X-axis directions, so as to grasp and insert the 4 cores 203 into the slots 201a of the corresponding housing 201 on the positioning fixture 380. Under the instruction of the control system, the magnetic core 203 does not need to be loaded into the housing 201 which is not assembled with the sealing ring 202 and is unqualified in glue amount detection in the assembling process, and the magnetic core assembling mechanism 343 may drive the corresponding material taking clamping jaw 3431 to transfer the gripped magnetic core 203 to the magnetic core caching mechanism 342 along the Y-axis direction for temporary storage. The core buffer mechanism 342 can reversely convey the core 203 relative to the core feeding mechanism 341, so that the core 203 is transferred to the beginning of the core feeding mechanism 341, and is conveniently transferred to the core feeding mechanism 341 for conveying. Of course, the core buffering mechanism 342 may also convey the cores 203 in a reverse direction with respect to the core feeding mechanism 341, and convey the cores 203 in a forward direction after accumulating a certain number of cores 203, so as to convey the cores 203 toward the core assembling mechanism 343.

Referring to fig. 10, the PIN pressing device 350 includes a first pressing head 351, a driver 352 connected to the first pressing head 351 in a one-to-one correspondence, a second pressing head 353, and a driver 354 connected to the second pressing head 353 in a one-to-one correspondence, wherein the first pressing head 351 and the second pressing head 353 are respectively disposed in correspondence with the PIN 2033 and the magnetic core 203. In the present embodiment, the pressing device includes 8 first pressing heads 351 and 4 second pressing heads 353. Preferably, in order to prevent the housing 201 from moving during the crimping process, the pressing PIN device 350 further includes an upper limiting member 355, a lower limiting member 356, a left limiting member 357 and a right limiting member 358 for limiting the housing 201 in the upper, lower, left and right directions.
