Those skilled in the art can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0033] Refer to Figures 1 to 4, A material taking device, comprising a robotic arm 100, a mounting plate 200, a first clamping assembly 300, a second clamping assembly 400 and a third clamping assembly 500; the mounting plate 200 is rotatably connected to the outer connecting end of the robotic arm 100; the first clamping assembly 300 is arranged on one side of the mounting plate 200, and the first clamping assembly 300 is used for clamping paired hardware parts 600; the second clamping assembly 400 is arranged on the other side of the mounting plate 200, and the second clamping assembly 400 is used for clamping a mold insert 700; the third clamping assembly 500 is arranged on the second clamping assembly 400, and the third clamping assembly 500 is used for clamping the sprue 810 of an injection-molded hardware part 800. The setting of the paired hardware parts 600 facilitates injection molding. The output end of the robotic arm 100 is connected to the mounting plate 200, and the use of the first clamping assembly 300, the second clamping assembly 400 and the third clamping assembly 500 is alternately switched. When transferring the hardware parts 600, the user controls the robotic arm 100 to descend, and the first power member 320 drives the clamping block 330 to clamp and transfer the hardware parts 600. When transferring the mold insert 700, the user controls the robotic arm 100 to flip, moves the robotic arm 100 above the mold insert 700, the robotic arm 100 descends, the slot 411a is inserted into the mold insert 700, and the magnet 440 adsorbs the mold insert 700. The robotic arm 100 is lifted, and after transferring the mold insert 700 to a designated position, the second power member 420 drives the ejector block 430 to eject the mold insert 700 so that it falls.

[0034] It should be noted that the hardware parts 600 are workpieces required for the pins of the injection-molded network filter housing. The pins of the network filter housing generally exist in pairs. Therefore, when injecting the network filter housing, the hardware parts 600 also need to be installed in pairs in the mold for injection molding. Therefore, the hardware parts 600 need to be loaded into the mold in pairs; the so-called injection-molded hardware part 800 is an aggregate of network filter housings that have not been disassembled after injection molding, and it still has a sprue 810, and the mold insert 700 is still embedded in the aggregate. After removing the mold insert 700, a cavity of the network filter housing can be formed. The removed mold insert 700 needs to be recycled and used in the next injection molding process.

[0035] In some embodiments, the first clamping assembly 300 includes: a support plate 310 connected to one side of the mounting plate 200; a first power member 320 disposed on the side of the support plate 310 close to the mounting plate 200; two clamping blocks 330 slidably disposed on the side of the support plate 310 away from the mounting plate 200, the clamping blocks 330 being drivingly connected to the first power member 320, and the two clamping blocks 330 being capable of approaching or separating relative to each other to clamp a pair of hardware parts 600, which is convenient for clamping. It can be understood that the support plate 310 can centrally arrange the first power member 320 and the clamping blocks 330, providing a mounting position for the first power member 320 and the clamping blocks 330. The provided support plate 310 also abuts against the hardware part 600 during the clamping process to prevent the hardware part 600 from being arched and deformed by the clamping.

[0036] In some embodiments, the first clamping assembly 300 further includes: sliders 340 provided in one-to-one correspondence with the clamping blocks 330, the sliders 340 being slidably disposed on the support plate 310 along the sliding direction line of the clamping blocks 330, the sliders 340 being drivingly connected to the first power member 320; connecting rods 350 provided in one-to-one correspondence with the sliders 340, one end of the connecting rod 350 being hinged to the corresponding slider 340, and the other end of the connecting rod 350 being hinged to the corresponding clamping block 330, making the clamping more firm. It can be understood that the provided sliders 340 and connecting rods 350 form a set of commutation mechanisms, causing the output power direction of the first power member 320 to change on the clamping blocks 330, so that the two clamping blocks 330 can approach or separate relative to each other. The clamping blocks 330, sliders 340, and connecting rods 350 can all be provided in several numbers.

[0037] In some embodiments, the second clamping assembly 400 includes: a connecting block 410 connected to the other side of the mounting plate 200, a clamping groove 411a being provided on the side of the connecting block 410 away from the mounting plate 200, the clamping groove 411a being used for clamping a mold insert 700; a second power member 420 disposed on the connecting block 410; a top block 430 disposed on the side of the connecting block 410 away from the mounting plate 200, the top block 430 being connected to the second power member 420; the second power member 420 being used to drive the top block 430 to eject the mold insert 700. It can be understood that the provided top block 430 prevents the mold insert 700 from being unable to come out of the clamping groove 411a, affecting the subsequent production process. The second power member 420 and the top block 430 are both provided in several numbers, and several top blocks 430 are arranged at intervals along the length direction of the connecting block 410, and the length direction of the top block 430 is perpendicular to the length direction of the connecting block 410.

[0038] In some embodiments, a clamping block 411 is detachably connected to the connecting block 410, the clamping groove 411a is provided on the clamping block 411, and the clamping block 411 is used for clamping different mold inserts 700. The detachably connected clamping block 411 is convenient for replacement, and several clamping blocks 411 can be provided.

[0039] In some embodiments, the connecting block 410 is provided with an embedding groove 412, and the top block 430 is movably embedded in the embedding groove 412. The embedded top block 430 is used for avoidance to facilitate clamping. It can be understood that the so-called movement means that the top block 430 can extend or retract from the embedding groove 412 under the drive of the second power member 420. When the top block 430 retracts into the embedding groove 412, the end of the top block 430 far from the bottom surface of the embedding groove is flush with the top end of the embedding groove 412. The top block 430 and the connecting block 410 are also connected by a guide rod, and the top block 430 can slide along the guide rod. The guide rod is used to limit the sliding direction of the top block 430. It can be understood that one guide rod can be provided, or two or more guide rods can be provided. Except for the edges of the bottom surface of the top block 430, the other edges are provided with chamfers. The so-called bottom surface refers to the surface of the top block 430 close to the embedding groove 412.

[0040] In some embodiments, the second clamping assembly 400 further includes a magnetic block 440. The magnetic block 440 is embedded in the card slot 411a. The magnetic block 440 is used to adsorb the mold insert 700 so that the mold insert 700 is sucked against the gravity. The magnetic block 440 can also be replaced by a suction cup or an adhesive block.

[0041] In some embodiments, the third clamping assembly 500 includes a clamping block 510 and a clamping cylinder 520. The clamping cylinder 520 is arranged on the connecting block 410. There are two clamping blocks 510, and the two clamping blocks 510 are respectively arranged on the two clamping arms 521 of the clamping cylinder 520. The two clamping blocks 510 are used to cooperate to clamp the sprue 810 of the injection-molded hardware 800 to facilitate clamping and transferring the injection-molded hardware 800.

[0042] In some embodiments, the connecting block 410 is further provided with an avoidance opening 413. The clamping block 510 is accommodated in the avoidance opening 413. The sprue 810 of the injection-molded hardware 800 can extend into the space between the two clamping blocks 510 through the avoidance opening 413 to be clamped by the two clamping blocks 510. It can be understood that the purpose of setting the avoidance opening 413 is to make reasonable use of the space of the connecting block 410, so that the second clamping assembly 400 and the third clamping assembly 500 are centrally arranged, improving the space utilization rate and reducing mechanical interference.

[0043] In some embodiments, the avoidance opening 413 is set to be rectangular, and the central axis of the clamping block 510 passes through the intersection point of the diagonals of the avoidance opening 413. The setting of the intersection point of the diagonals of the avoidance opening 413 on the central axis of the clamping block 510 is used to calibrate the position of the injection-molded hardware 800, reduce the center-of-gravity offset of the combination of the second clamping assembly 400 and the third clamping assembly 500, and avoid increasing the burden on the robotic arm 100. The avoidance opening 413 can also be set to be circular, oval, trapezoidal, etc.

[0044] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the relevant art.
