[0003] In the production process of the acoustic structure, the metal insert is supplied, the metal insert is picked up by a mechanical arm and placed into an injection molding mold for plastic encapsulation forming, and then the formed product is taken out by the mechanical arm, placed in a tray, transferred to a cutting device to remove the exposed end of the metal insert, and the whole process production is completed.
[0004] There are many defects in the traditional process. Firstly, the metal insert is generally supplied by cutting and placing, which results in low supply efficiency and poor position accuracy.

[0047] Specific implementation process and principle description: In the present case, the metal insert 120 of the acoustic structure is punched and bent on a metal material belt, so the metal insert 120 is carried on the metal material belt.
[0048] The material belt is supplied by the feeding tray 111, generally by traction combined with unwinding, which belongs to the prior art and will not be described here. When the material belt passes through the insert punching and feeding part 112, the metal insert 120 is punched off the material belt and then supplied. The metal insert picking and transferring part 131 picks up the metal insert 120 and places it on the metal insert loading position 1220 of the insert tray.
[0049] When the metal insert loading position 1220 of the insert tray is full, it will linearly displace and automatically cooperate with the automatic turnover mechanism 22. At this time, the insert material grabbing 2222 will pick up the metal insert on the insert tray and place it in the injection molding cavity of the injection mold. The horizontal injection mold line 21 performs plastic molding on it. The molded injection molded part is picked up by the injection molded part transferring material grabbing 2221 and placed on the injection molded part loading position 1210 of the injection molded part array loading platform 121. It should be noted that after the injection molded part picking operation is performed, the metal insert placing operation is performed. In this way, the tide cooperation is realized, the docking time is shortened, and the injection molding operation efficiency is improved.
[0050] Then the injection molded part picking and transferring part 141 of the injection molded part transferring mechanism 14 picks up the injection molded part and transfers it to the injection molded part supporting loading platform 311 of the injection molded part supporting and transferring mechanism 31. The injection molded part supporting loading platform 311 rotates 90° and is opposite to the automatic bending and material removing mechanism 32. The injection molded part supporting loading platform 311 is linearly displaced into the automatic bending and material removing mechanism 32 to perform bending operation on the exposed end. Specifically, the exposed end is bent by the folding and breaking part 321 in forward and reverse high-frequency poking to make the exposed end break.
[0051] After the breaking operation is completed, the injection molded part supporting loading platform 311 exits the automatic bending and material removing mechanism 32. At this time, the injection molded part on the injection molded part supporting loading platform is picked up by the cavity corresponding turnover mechanism 34, and is transferred to the tray position matching the injection molded cavity according to the injection molded part corresponding injection molded cavity information.
[0052] The automatic bending and material removing mechanism 32 is described in detail as shown in Figure 16 and Figure 17 The automatic bending and material removing mechanism 32 includes a plurality of pressure contact ends 322 with lifting displacement. Any pressure contact end 322 is provided with a folding and breaking part 321 penetrating the pressure contact end with lifting displacement. The automatic bending and material removing mechanism 32 is provided with a high-frequency cam transmission mechanism 323 communicating with a plurality of folding and breaking parts 321. The pressure contact end 322 can press and lock the main body of the injection molded part. The high-frequency cam transmission mechanism 323 can drive the folding and breaking part 321 to perform high-frequency lifting displacement to break the exposed end. The folding and breaking part 321 is generally a poking piece structure. When the breaking operation is performed, it first presses the exposed end, then relatively slides and misplaces to the bottom of the exposed end, and then upwardly displaces. The high-frequency up-and-down sliding realizes efficient breaking of the exposed end.
[0053] In one specific embodiment, the automated tray device has an exposed classification and detection bearing mechanism 35 at one end away from the injection molded part support and transfer mechanism. The classification and detection bearing mechanism is provided with a temporary storage platform 351 with rotational displacement. The temporary storage platform 351 is provided with a plurality of temporary storage slots 352 that correspond one-to-one with the injection molded cavity. The cavity corresponding turnover mechanism has injection molded part turnover displacement between the injection molded part support platform and the temporary storage platform.
[0054] Specifically, the encapsulation process for acoustic structural components requires pre-production inspection because production lines frequently need material changes or adjustments. Pre-production sampling inspection is difficult to implement due to space constraints and operational safety concerns. This case utilizes a temporary storage platform (351) design. Pre-production alignment with the corresponding rotation mechanism within the equipment allows for the receiving of the current test material. After receiving, the material is rotated outwards, allowing operators to pick up the corresponding injection molded parts for inspection. This enables adjustments to the injection molding line and, based on the inspection results, selective closure of injection cavities. This improves the pass rate and avoids mass scrapping caused by pre-production adjustment issues.
[0055] In one specific embodiment, the insert punching supply unit 112 includes a material conveying track 1121 and a punching platform 1122 disposed on the material conveying track path. The top of the punching platform is provided with a punching supply window, and the bottom of the punching platform is provided with a lifting punching end that corresponds one-to-one with the punching supply window and has a lifting punching displacement.
[0056] That is, the metal insert can be ejected by lifting the punching end, thus facilitating the external picking and transfer of materials.
[0057] In one specific embodiment, the insert tray includes a material receiving station and a material feeding station adjacent to the injection molding part aligning platform. The metal insert pick-up and transfer unit has a linear turnover displacement between the punching platform and the material receiving station, and the linear displacement direction of the metal insert pick-up and transfer unit is perpendicular to the linear displacement direction of the insert tray. More specifically, the supporting turnover mechanism includes a linear switching position carrier 123 with linear displacement for mounting the insert tray. The linear switching position carrier 123 is provided with a rotary displacement platform 1231 with rotational displacement, and the insert tray is disposed on the rotary displacement platform.
[0058] Specifically, the metal inserts are aligned in the same direction on the metal strip, and there are reversing feeding and symmetrical turning feeding at the rear end. The design of the rotary displacement stage 1231 facilitates the reversing and alignment picking requirements.
[0059] In one specific embodiment, the turnover cantilever has a lifting displacement, a first horizontal linear displacement along the mold opening and closing direction of the injection mold, and a second horizontal linear displacement for turnover between the injection mold and the supporting turnover mechanism, wherein the first horizontal linear displacement and the second horizontal linear displacement are perpendicular to each other.
[0060] The bottom end of the turnover cantilever is provided with a pivotally connected turnover table and a turnover driving source 2210 connected with the turnover table. The turnover table is detachably provided with a linkage carrier. The injection molded part transfer gripper and the insert part gripper are arranged on the linkage carrier.
[0061] In this way, the displacement requirement and the turnover efficient operation requirement are met.

The injection molded part pickup parts are provided with a plurality of negative pressure pickup ends 22212.
[0063] The insert part gripper is provided with a plurality of metal insert pickup parts 22221 corresponding to the metal insert loading positions. The metal insert pickup parts are provided with a magnetic or negative pressure suction end.
[0064] In this way, the stability requirement of the transfer and pickup of the metal insert and the injection molded part is met.

Each disc-arranging column is provided with a plurality of disc-arranging positions. Each disc-arranging column is provided with a corresponding hole-distributing and disc-arranging mechanism. Each hole-distributing and disc-arranging mechanism is provided with a plurality of hole-distributing and disc-arranging pickup parts corresponding to the loading positions. The injection molded part supporting platform is provided with a feeding position corresponding to the injection molded part transfer mechanism, a loading position corresponding to the automatic bending and loading mechanism, and a switching position corresponding to the two hole-distributing and disc-arranging mechanisms.
[0066] Specifically, the injection molded part is received at the feeding position. The feeding and breaking operation is performed at the loading position. The switching operation is performed at the switching position. Each hole-distributing and disc-arranging mechanism performs the pickup of the injection molded part in the corresponding disc-arranging column and the corresponding disc-arranging operation. In this way, the operation is more efficient.
[0067] In one embodiment, as shown in Figure 18 The hole-distributing and disc-arranging mechanism 33 includes a plurality of disc-arranging groups 4. Each disc-arranging group 4 includes two oppositely spaced disc-arranging areas 41 and a disc-arranging and unloading area 42 between the two disc-arranging areas. Each disc-arranging area corresponds to a disc-arranging column. The disc-arranging area 41 is provided with a disc-arranging jacking mechanism 410. The disc-arranging and unloading area 42 includes a conveying track 420 connected with any disc-arranging area.
[0068] In specific operation, the disc-arranging jacking mechanism 410 in the disc-arranging area 41 supplies the disc-arranging. When the disc-arranging is full, it is conveyed to the disc-arranging and unloading area 42 by the conveying track 420. The full disc-arranging in the current disc-arranging and unloading area 42 is unloaded by the hole-distributing and disc-arranging pickup part or an external mechanical arm.
[0069] The forming method of the insert implanting forming line of the acoustic structure is specifically described as follows: The metal insert is automatically supplied, the material belt supply mechanism is operated to supply the material belt, the insert punching supply part punches off the metal insert on the material belt from the material belt and then ejects and supplies the metal insert, the metal insert picking and transferring part picks up the ejected and supplied metal insert and transfers it to the metal insert loading position of the insert tray, when the metal insert loading position is full, the insert tray is displaced to the opposite position of the insert material grab, the insert material grab picks up the metal insert and embeds it into the injection mold of the horizontal injection mold line; The injection molded part is unloaded and transferred, the horizontal injection mold forms the injection molded part on the metal insert after plastic packaging forming, and the transfer boom is transferred, at this time, the metal insert feeding and the injection molded part discharging are in a tidal flow, the injection molded part transfer grab picks up the injection molded part and places it on the injection molded part array loading table, and the injection molded part transfer mechanism picks up the injection molded part on the injection molded part array loading table and places it on the injection molded part supporting loading table; The exposed end is broken and removed, the injection molded part supporting loading table is displaced into the automatic bending and material removing mechanism, and the automatic bending and material removing mechanism breaks the exposed end by high-frequency forward and reverse poking to bend the exposed end; The injection molded part is placed into the finished product tray in the corresponding tray position according to the source information of the injection molded hole position of the injection molded part.
