[0051] Example 1

[0052] like Figure 1 、 Figures 3 to 15 As shown, a high-precision micro-speaker three-magnetic circuit automatic assembly equipment includes a frame 100, a feeding mechanism 200 arranged on the frame 100, and a loading assembly mechanism 300, a dispensing mechanism 400, a heating mechanism 500 and a unloading mechanism 600 are arranged around the feeding mechanism 200; the feeding mechanism 200 is used to circulate the jig 101, the loading assembly mechanism 300 is used to load parts onto the jig 101, the dispensing mechanism 400 is used to dispense glue on the parts in the jig 101, the heating mechanism 500 is used to heat the parts after dispensing glue and transport the heated jig 101 to the feeding mechanism 200, the feeding mechanism 200 is also used to transport the heated jig 101 to the unloading mechanism 600, and the unloading mechanism 600 is used to unload the parts in the jig 101.

[0053] In actual use, a plurality of empty jigs 101 are pre-placed on the feeding mechanism 200. These jigs 101 pass through the feeding mechanism 200, the gluing mechanism 400, the heating mechanism 500, and the unloading mechanism 600 in sequence, and are loaded, assembled, gluing, and heated in sequence, and finally go to the unloading mechanism 600 for unloading of parts.

[0054] Specifically, the automatic assembly equipment of this embodiment, by providing a feeding mechanism 200, a loading and assembly mechanism 300, a gluing mechanism 400, a heating mechanism 500 and a unloading mechanism 600, realizes full automation of the loading, assembly, gluing, heating and unloading of the parts of the micro speaker, thereby solving the problem of low efficiency in the assembly of the parts of the micro speaker.

[0055] See Figures 3 to 8 , Figure 3 It shows the structural diagram of the feeding mechanism 200 and the defective product discharge mechanism 700. Figure 4 shows a schematic structural diagram of the first delivery channel 201, Figure 5 Another structural diagram of the first delivery channel 201 is shown. Figure 6 shows a schematic diagram of the internal structure of the first delivery channel 201, Figure 7 shows a schematic structural diagram of the second delivery channel 209, Figure 8 FIG. 2 shows a schematic structural diagram of a defective product discharge mechanism 700 .

[0056] from Figure 3 It can be seen that the feeding mechanism 200 includes a first conveying channel 201 and a second conveying channel 209 spaced apart from the first conveying channel 201. Under normal circumstances, the first conveying channel 201 conveys the fixture 101 to the loading assembly mechanism 300, the dispensing mechanism 400 and the heating mechanism 500 in sequence, and the conveying direction of the second conveying channel 209 is opposite to the conveying direction of the first conveying channel 201.

[0057] Among them, the first conveying channel 201 includes a conveying base 202, a conveying drive component 203, multiple positioning drive components 204 and multiple sliding components 205, all of which are arranged on the conveying base 202. The conveying base 202 is provided with a first slide 206 above the sliding component 205. The first slide 206 is used to place the fixture 101. The positioning drive component 204 is used to drive the sliding component 205 to move up and down. The sliding component 205 is used to contact the fixture 101. The sliding component 205 is connected to the output end of the positioning drive component 204 in a sliding manner in the horizontal direction; the conveying drive component 203 includes a conveying drive member 207 and a slider 208. The conveying drive member 207 is used to drive the slider 208 to move horizontally. The slider 208 is connected to the sliding component 205 in a sliding manner in the vertical direction.

[0058] In this embodiment, the conveying drive assembly 207 comprises a motor, a synchronous pulley, a synchronous belt, a screw, and a nut, which together drive the slider 208 laterally. The positioning drive assembly 204 comprises a cylinder and a connecting block, which together drive the slider 205 upward and downward. The slider 208 drives the slider 205 in lateral movement. Since the slider 208 and the slider 205 are vertically slidably connected, the vertical movement of the slider 205 does not affect the slider 208. Furthermore, since the positioning drive assembly 204 is horizontally slidably connected to the slider 205, it can drive the slider 205 upward and downward without being affected by the horizontal movement of the slider 205. This allows the slider 205 to rise and contact the jig 101. Simultaneously, the conveying drive assembly 203 drives the slider 208 in lateral movement, thereby driving the slider 205 in lateral movement, thereby driving the jig 101 in the first chute 206.

[0059] Specifically, the first chute 206 is provided with an array of first through-holes 213, and the upper end of the sliding assembly 205 is provided with a plurality of first positioning posts 214, each corresponding to the first through-holes 213. The first positioning posts 214 are used to insert the jig 101. The output end of the positioning drive assembly 204, which passes through the upper end of the conveying base 202, is further provided with a linkage plate 215. One side of the linkage plate 215 protrudes above the first chute 206. One side of the linkage plate 215 is provided with a second positioning post 216 protruding downward. The second positioning post 216 is used to insert the jig 101. After the positioning drive assembly 204 drives the sliding assembly 205 upward, the first positioning posts 214 pass through the first through-holes 213 and are inserted into the corresponding positions of the jig 101, thereby achieving interference with the jig 101. In addition, when the jig 101 moves to the corresponding position of the loading and assembly mechanism 300 or the dispensing mechanism 400, the positioning drive component 204 drives the sliding component 205 to descend, and the first positioning column 214 is separated from the jig 101. At the same time, the linkage plate 215 drives the second positioning column 216 to be inserted into the corresponding position of the jig 101, so that the jig 101 is fixed on the first slide groove 206, which facilitates the corresponding loading, assembly or processing of the parts on the jig 101.

[0060] In this embodiment, the second conveying channel 209 includes a channel conveyor belt 210, a channel conveyor belt driver 211 for driving the channel conveyor belt 210, and a channel push-in assembly 212 for transferring the fixture 101 from the channel conveyor belt 210 to the first chute 206. The channel conveyor belt 210 is provided on the frame 100 and is located on one side of the first chute 206. In actual use, the parts on the fixture 101 are heated by the heating mechanism 500 and then transported in reverse to the unloading mechanism 600 via the channel conveyor belt 210. The unloading mechanism 600 unloads the parts from the fixture 101. Preferably, the channel conveyor belt driver 211 is composed of a motor, a tensioning pulley, and other components. The principle of driving the conveyor belt belongs to the prior art and will not be repeated here.

[0061] In this embodiment, the frame 100 is provided with a defective product discharge mechanism 700 at the end of the first conveying channel 201, and the defective product discharge mechanism 700 includes a first temporary storage chute 701, a second temporary storage chute 702, a separation drive assembly 703 and a defective product pushing drive member 704, all of which are arranged on the frame 100. The two ends of the first temporary storage chute 701 are respectively connected to the first chute 206 and the feeding end of the heating mechanism 500, and one side of the second temporary storage chute 702 is connected to one side of the first temporary storage chute 701. The separation drive assembly 703 is used to push the fixture 101 located in the first temporary storage chute 701 to the second temporary storage chute 702, and the defective product pushing drive member 704 is used to push the fixture 101 located in the second temporary storage chute 702 away from the defective product pushing drive member 704.

[0062] In actual use, the automatic assembly equipment of this embodiment is also equipped with an AOI detection mechanism 800, whose specific function is to detect whether there are defects in the parts after assembly or gluing on the fixture 101, and the AOI detection mechanism 800 is generally set after the gluing mechanism 400. When the AOI inspection mechanism 800 detects that there are defects in the parts on the jig 101, when the jig 101 moves to the first temporary storage chute 701, the separation drive component 703 pushes the jig 101 to the second temporary storage chute 702, and the defective product push-in drive member 704 pushes the jig 101 to a position farther away from the second temporary storage chute 702, so that the jig 101 with defective parts is accumulated in the second temporary storage chute 702, and is moved out by a robot or manually after the second temporary storage chute 702 is full; and when the AOI inspection mechanism 800 does not detect that there are defects in the parts on the jig 101, the jig 101 directly passes through the first temporary storage chute 701 and the second temporary storage chute 702 and enters the feeding end of the heating mechanism 500 for heating.

[0063] It should be noted that the separation drive assembly 703 and the defective product pushing drive member 704 of this embodiment are preferably cylinders, which can speed up the sorting of the fixture 101.

[0064] See Figures 9 to 11 , Figure 9 Schematic diagram of the structure of the heating mechanism 500 is shown. Figure 10 Schematic diagram of the structure of the hot pressing mechanism 501 is shown. Figure 11 A schematic structural diagram of an oven 508 and a reflow line 509 is shown.

[0065] from Figures 9 to 11 It can be seen that the heating mechanism 500 includes a hot pressing mechanism 501, an oven 508 and a reflow line 509. The hot pressing mechanism 501 includes a hot pressing base 502, a hot pressing assembly 503 provided on the hot pressing base 502, and a hot pressing assembly 503 provided on the hot pressing base 502. And a hot pressing push-in component 504; located on one side of the hot pressing component 503, the hot pressing base 502 is provided with a second slide groove 505; located at one end of the second slide groove 505, the hot pressing base 502 is provided with a first opening 506; the frame 100 is also provided with a heating pushing component 507 for pushing the jig 101 located at the feeding mechanism 200 into the first opening 506; the hot pressing pushing component 504 is used to push the jig 101 located at the second slide groove 505 to the heating position of the hot pressing component 503, and the hot pressing component 503 is used to hot press the parts in the jig 101; the oven 508 is provided with a feed port at one end close to the hot pressing mechanism 501, and a discharge port is provided at the other end of the oven 508, the second slide groove 505 is connected to the feed port, the return line 509 is connected to the discharge port, and the return line 509 is used to transfer the jig 101 to the feeding mechanism 200.

[0066] In this embodiment, parts that pass the AOI inspection mechanism 800 and pass through the second temporary storage chute 702 are transported to the second temporary storage chute 702. The heated pusher assembly 507 pushes the jig 101 into the second chute 505, and so on until the second chute 505 is full of jigs 101. When the second chute 505 is full of jigs 101, the hot press pusher assembly 504 pushes the row of jigs 101 on the second chute 505 under the hot press assembly 503, which performs a hot press process on the parts within the jigs 101. After the hot pressing treatment is completed, the hot pressing pushing component 504 pushes all the above-mentioned jigs 101 away from the hot pressing component 503 and enters the oven 508 through the feeding port of the oven 508 for baking. Then, the heating pushing component 507 pushes the jigs 101 containing qualified parts into the second chute 505. This process is repeated until the row of jigs 101 that first entered the oven 508 is pushed to the return line 509, and the return line 509 transports the jigs 101 one by one to the second conveying channel 209.

[0067] Specifically, the reflow line 509 includes a first reflow conveyor belt 510, a reflow push assembly 511, and a second reflow conveyor belt 512, all of which are arranged on the frame 100. The first reflow conveyor belt 510 is connected to the discharge port of the oven 508. The reflow push assembly 511 is used to push the jig 101 located on the first reflow conveyor belt 510 to the second reflow conveyor belt 512, and the second reflow conveyor belt 512 is connected to the feeding mechanism 200. Preferably, the first reflow conveyor belt 510 is arranged perpendicular to the second reflow conveyor belt 512. The reflow push assembly 511 and the heating push assembly 507 have the same operating principles. The reflow push assembly 511, the heating push assembly 507, and the hot pressing push assembly 504 are preferably cylinders. The hot pressing assembly 503 selected in this embodiment is all prior art. Its structure and operating principle can be referred to the prior art and will not be described in detail here.

[0078] Finally, it should be noted that the fixture 101 of this embodiment is driven to move laterally by the first conveying channel 201. Since the first conveying channel 201 adopts a modular structure design, that is, in the above embodiment, different numbers of feeding assembly mechanisms 300, dispensing mechanisms 400 and AOI detection mechanisms 800 can be installed according to the processing requirements of the product, such as Figure 2 As shown in FIG, a set of feeding assembly mechanism 300, dispensing mechanism 400 and AOI detection mechanism 800 are provided; Figure 1 As shown in the figure, two sets of loading and assembly mechanisms 300, a dispensing mechanism 400, and an AOI inspection mechanism 800 are provided. By reconfiguring the corresponding first and second conveying channels 201 and 209, different parts can be processed, assembled, and heated. Furthermore, different processing mechanisms with different functions can be installed according to actual conditions.

Among them, Example 2 is a high-precision micro-speaker three-magnetic circuit automatic assembly equipment for assembling the main magnetic finished product, and Example 1 is a high-precision micro-speaker three-magnetic circuit automatic assembly equipment for assembling the three magnetic finished products. This embodiment also discloses a high-precision micro-speaker three-magnetic circuit automatic assembly equipment, which is used to assemble the main magnetic finished product. By changing the loading content of the loading assembly mechanism 300, the loading assembly mechanism 300, the dispensing mechanism 400 and the position of the AOI detection mechanism 800, the equipment of this embodiment can be converted into equipment for assembling the side magnetic finished product. The assembly equipment for the side magnetic finished product is as follows. Figure 16As shown, except that the loading assembly mechanism 300 is different from that of Example 1 and the unloading mechanism 600 is the same as that of Example 2, the remaining structures are the same as those of the equipment in Example 1. The loading assembly mechanism 300 in this embodiment loads the edge magnet, and its structure and principle belong to the existing technology and will not be repeated here.
