In order to reduce the damage caused by the vibration motor of the mobile phone to the electrical components inside the mobile phone during the vibration process, a buffer shrapnel is usually installed outside the vibration motor of the mobile phone, and an elastic piece is arranged between the buffer shrapnel and the motor. Buffer blocks or damping sheets are respectively arranged at both ends of the motor, the buffer shrapnel, and the inner side of the buffer shrapnel to buffer the vibration of the motor and reduce the vibration impact of other components inside the mobile phone.

At present, manual work is often used to attach the damping sheet to the buffer shrapnel. Due to the very small size of the buffer shrapnel and damping sheet, the efficiency of manual work is low and the production quality cannot be guaranteed, so automation equipment is urgently needed to replace manual work. Since the cushioning shrapnel includes two elastic supporting legs clamped at a certain angle, and the two elastic supporting legs can be elastically folded, the existing retrieving mechanism is unable to perform the action of clamping the buffering shrapnel.

In this regard, it is necessary to provide a pick-up and unloading device for the cushioning elastic pieces, so as to transfer the cushioning elastic pieces and facilitate the application of the damping pieces to the cushioning elastic pieces by using automated equipment.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

As shown in Figure 1, the cushioning shrapnel a10 used for the vibration motor of a mobile phone includes two elastic supporting feet a11, and one end of the two elastic supporting feet a11 is connected and clamped at a certain angle, so that the structure of the buffering shrapnel a10 is approximately V type. The ultra-thin damping sheet b10 needs to be attached to the inner side of an elastic supporting foot a11. It can be understood that the size of the buffer elastic piece a10 used for the vibration motor of the mobile phone is very small, and the size of the ultra-thin damping piece b10 is even larger. In this embodiment, the size of the damping piece is 1.8mm*1.8mm*0.18mm. It can be understood that the two elastic supporting feet a11 can be elastically deformed to be folded or unfolded.

As shown in Figure 2-4, the damping sheet automatic placement machine includes a frame 100, and the lower part of the frame 100 is provided with control components such as a motor, a control circuit, and a PLC, and the above-mentioned multiple components are respectively arranged on the upper side of the frame 100. A device is also provided with a housing 200 on the outside of the frame 100, which covers most of the above-mentioned mechanisms, leaving only the operating parts of the loading device 400 and the unloading device 500 outside, so that the damping sheet The fully automatic placement machine performs loading and unloading without interfering with its internal operations. The casing 200 is also provided with mechanisms such as an operation panel and a monitor, so as to monitor and operate the damping sheet automatic placement machine.

3-4, on the upper side of the frame 100, two conveying channels 300 are arranged in parallel on the side away from the loading device 400 and the unloading device 500, and the loading device 400 and the unloading device 500 are located An affixing device 800 is provided outside one end of the two transmission channels 300 and on the other end side of the two transmission channels 300 . The two transmission channels 300 are respectively slidingly provided with cushioning elastic sheet bearing mechanisms 900 . The retrieving device 600 is arranged between the conveying channel 300 and the feeding device 400, and is used to transfer the cushioning shrapnel a10 at the feeding device 400 to the buffering shrapnel carrying mechanism 900 at the conveying passage 300, and the unloading device 700 is arranged on the conveying Between the passage 300 and the unloading device 500 , it is used to move the cushioning shrapnel a10 pasted with the ultra-thin damping sheet b10 in the buffer shrapnel carrying mechanism 900 at the conveying passage 300 to the unloading device 500 for unloading. At the other end of the two transmission channels 300, an automatic feeding device 1100 for supplying the ultra-thin damping sheet b10 is fixedly installed, and the pasting device 800 moves between the automatic feeding device 1100 and the two transmission channels 300 to place the ultra-thin damping sheet b10 It is transferred to the buffer elastic piece a10 in the buffer elastic piece carrying mechanism 900 at the transmission channel 300, and the ultra-thin damping piece b10 is attached to the inner side of an elastic supporting foot a11 of the buffer elastic piece a10.

It can be understood that, as shown in FIG. 3 and FIG. 4 , the loading mechanism 420 is only provided with a cushioning shrapnel loading level 421, which is to save space and make the layout more compact, and the damping sheet automatic placement machine passes through two conveyors. The channel 300 realizes loading and unloading sequentially, so even if the retrieving device 600 stops working for a short time during the process of replacing the loading tray P at the loading level 421 of the buffer shrapnel, it will not cause the sticking action of the sticking device 800 An interruption occurred. The unloading mechanism 520 is provided with two buffer shrapnel lowering positions 521, because the size of the unloading tray P' is smaller than that of the loading tray P, and there is enough space above the frame 100 to accommodate the two buffer shrapnel lower parts. The unloading mechanism 520 of material level 521. The buffer shrapnel a10 in the unloading tray P' is arranged in 14*4, which is also inconsistent with the number of buffer shrapnel a10 picked and placed by the unloading device 700 at a time, so the unloading device 500 is also provided with a waiting position 522 for unloading.

Please return to Fig. 3 and Fig. 4 again, the retrieving device 600 includes a first gantry 610 across the two conveying channels 300 and the feeding mechanism 420 and a buffer shrapnel feeding end 620, and the buffer shrapnel picking end 620 is along the The first gantry 610 slides to transfer the buffer shrapnel a10 at the material loading position to the conveying channel 300; as shown in FIG. 3, FIG. 4, and FIG. The second gantry 710 of the mechanism 520 and the discharge end 720 of the buffer shrapnel, the discharge end 720 of the buffer shrapnel slides along the second gantry 710 to transfer the buffer shrapnel a10 attached with the ultra-thin damping sheet b10 at the transmission channel 300 to the material discharge level. Wherein, the first gantry 610 and the second gantry 710 are parallel. Based on the fact that the first gantry 610 and the second gantry 710 are arranged in parallel and perpendicular to the two conveying channels 300, the structure of the fully automatic damping sheet placement machine provided by the present invention is very compact, and the buffer elastic sheet picking terminal 620 The buffer shrapnel a10 at the feeding device 400 can be transferred to any transmission channel 300, and the buffer shrapnel discharge terminal 720 can also transfer the buffer shrapnel a10 attached to the ultra-thin damping sheet b10 at the two transfer channels 300 to With the unloading device 500, the two actions do not interfere with each other, which improves production efficiency.

Please refer to FIG. 5 and FIG. 7 again. In this embodiment, the buffer shrapnel fetching end 620 includes a positioning plate 621 and eight buffer shrapnel fetching mechanisms 622 arranged on the positioning plate 621 in a straight line. As shown in FIG. 8 and FIG. 9 , the distance between the eight buffer shrapnel retrieving mechanisms 622 can be adjusted by itself to automatically adapt to the spacing of the buffer shrapnel a10 in the feeding tray P and the positioning fixture 930 at the buffer shrapnel carrying mechanism 900 Pitch. Similar to the buffer shrapnel retrieving end 620, as shown in FIG. 10, the buffer shrapnel discharge end 720 also includes a positioning plate 721 and 8 buffer shrapnel unloading mechanisms 722 arranged on the positioning plate 721 along a straight line. Moreover, the distance between the eight buffer shrapnel unloading mechanisms 722 can be adjusted to automatically adapt to the distance between the positioning fixtures 930 at the buffer shrapnel carrying mechanism 900 and the distance between the buffer shrapnel a10 in the lower tray P′. It can be understood that the number of positioning jigs 930 at the cushioning shrapnel bearing mechanism 900 is also eight. In other embodiments different from this embodiment, the buffer shrapnel take-up mechanism 622 of the buffer shrapnel fetching terminal 620, the buffer shrapnel unloading mechanism 722 of the buffer shrapnel discharge end 720, and the buffer shrapnel loading mechanism 900 The number of the positioning jigs 930 can also be any other number, as long as the number of the three is kept consistent.

The buffer shrapnel retrieving terminal 620 includes a positioning plate 621, a buffer shrapnel retrieving mechanism 622, and a driving mechanism (not shown in the figure), and 8 buffer shrapnel retrieving mechanisms 622 are vertically arranged, and 8 buffer shrapnel retrieving mechanisms The distance between 622 is adjustable, and the driving mechanism is used to drive the distance between the 8 cushioning shrapnel fetching mechanisms 622 to increase or decrease to correspond to the different distances between the tray P and the positioning fixture of the fixture carrying mechanism 900 . More specifically, as shown in Fig. 5, Fig. 7-Fig. 9: 8 buffer shrapnel retrieving mechanisms 622 arranged on the positioning plate 621 are arranged in a transverse direction, and the adjacent buffer shrapnel retrieving mechanisms 622 pass through the same The horizontal column pins of the length are movably connected, and a buffer shrapnel fetching mechanism 622 at one end is fixedly arranged on one end side of the positioning plate 621, and the driving mechanism drives a buffer shrapnel fetching mechanism 622 at the other end, and then passes through the transverse post. The pin drives seven movable buffer shrapnel retrieving mechanisms 622 to move synchronously, so that the distance between the 8 buffer shrapnel retrieving mechanisms 622 can be adjusted to increase or decrease, so as to adapt to the distance between the storage tanks of the material tray P and The distance between the positioning fixtures of the elastic sheet carrying mechanism 900 is buffered. It can be understood that the structure of the buffer shrapnel discharge end 720 for adjusting the distance between the buffer shrapnel discharge mechanisms 722 is the same as that of the buffer shrapnel fetching end 620 , so it will not be repeated here.

It can be understood that since the two elastic supporting feet a11 of the buffer elastic piece a10 can be elastically opened and closed, the two elastic supporting feet a11 directly clamping the buffer elastic piece a10 may not be clamped stably. For this, the buffer shrapnel retrieving mechanism 622 and the buffer shrapnel unloading mechanism 722 that are similar to each other are used to clamp the buffer shrapnel a10 in the retrieving device 600 and the unloading device 700 . As shown in Figures 10-12, the buffer shrapnel unloading mechanism 722 is used as an example for illustration: the buffer shrapnel unloading mechanism 722 includes a gripper 722a and a block 722b, and the two grippers 722a are respectively locked from the outside of the buffer shrapnel a10. Holding the two elastic supporting feet a11, the clamping block 722b can extend between the two elastic supporting feet a11 to hold the two elastic supporting feet a11 from the inner side of the buffer elastic piece a10. When the buffer shrapnel unloading mechanism 722 clamps the buffer shrapnel a10, the clamping block 722b first extends downward between the two elastic supporting feet a11, and clamps the two elastic supporting feet a11 from the inside to the outside to keep them in an open state; The first clamping claw 722a moves to the outside of the two elastic supporting legs a11 to clamp the two elastic supporting legs a11 from the outside to the inside, so that the clamped buffer spring a10 cannot be deformed, and the buffer spring a10 is reliably clamped by the buffer spring discharge mechanism 722 Hold, and then realize taking and placing the buffer shrapnel a10.

Preferably, as shown in FIG. 11 , at least part of the clamping block 722b is located between the two clamping jaws 722a, and together with the clamping jaws 722a, clamps the inner and outer sides of the two elastic supporting feet a11. According to this technical solution, a part of the elastic support foot a11 is clamped by the inner and outer sides at the same time, so that the buffer elastic piece a10 is positioned more reliably.

Referring to Figure 10 and Figure 11 again, the clamping block 722b includes a clamping portion 722b1 for extending into the space between the two elastic supporting legs a11 and a protrusion located on the upper side of the clamping portion 722b1 and protruding to the left and right sides part 722b2, the lower side of the protruding part 722b2 is used to abut against the upper side of the two elastic supporting feet a11. The setting of the protruding part 722b2 can limit the vertical position of the buffer elastic piece a10 held by the clamping block 722b and the two clamping jaws 722a, so as to prevent the The position of the held buffer shrapnel a10 is shifted.

In a preferred embodiment, the protruding portion 722b2 and the two clamping jaws 722a are arranged in an offset manner. Different from this embodiment, the protruding portion 722b2 is disposed on the front side and/or the rear side of the two jaws 722a. According to the above technical solution, the protruding portion 722b2 does not interfere with the jaw 722a.

In another preferred embodiment, the opposite sides of the lower ends of the two jaws 722a protrude to form a limiting portion (not shown in the figure), and the upper side of the limiting portion is used to abut against the bottom of the two elastic supporting feet a11 side. The limiting part cooperates with the protruding part 722b2, so that the buffer elastic piece a10 is reliably limited on the upper and lower sides.

Referring again to FIG. 11 , the discharge end 720 of the buffer shrapnel also includes a clamping driver 722c that drives the two jaws 722a to open or close, and the clamping block 722b is fixedly disposed between the two jaws 722a. Specifically, the claws 722b are fixedly arranged relative to the positioning plate 721, and the clamping driver 722c drives the two claws 722a to face the claws 722b.

Combined with Figure 10-Figure 12, the working process of the buffer shrapnel discharge end 720 will be described in detail:

When the buffer shrapnel unloading mechanism 722 clamps the buffer shrapnel a10 from the discharge tray P', the clamping block 721b first moves down and extends between the two elastic support feet a11, and clamps the two elastic support feet a11 from the inside out so that It remains in an open state, at this time, the clamping portion 722b1 extends between the two elastic supporting legs a11, and the lower side of the protruding portion 722b2 is used to abut against the upper side of the two elastic supporting legs a11;

Subsequently, the clamping driver 722c drives the two jaws 721a to clamp in the direction of the block 721b, so as to clamp the two elastic support feet a11 from the left and right outer sides of the buffer elastic piece a10, so that the buffer elastic piece a10 is reliably limit;

The buffer shrapnel unloading mechanism 722 drives a buffer shrapnel unloading mechanism 722 at one end to move through the drive mechanism 723, and then drives the seven buffer shrapnel unloading mechanisms 722 to move synchronously, thereby adjusting the distance between the eight buffer shrapnel unloading mechanisms 722, Adapt to the distance from the storage tank of the unloading tray P';

The clamped buffer shrapnel a10 moves along the gantry 710 to the lower material level 521 of the buffer shrapnel, and puts the 8 buffer shrapnel a10 held by the buffer shrapnel unloading mechanism 722 into the corresponding unloading tray P', then clips The holding driver 722c drives the two jaws 721a to move outward to release the clamping of the buffer spring a10. At this time, the two elastic support legs a11 of the buffer spring a10 are slightly opened, and the discharge end 720 of the buffer spring moves upwards and drives the clip. The claw 721a and the block 721b move upwards synchronously and separate from the buffer elastic piece a10.

The buffer shrapnel feeding end 620 shown in FIG. 5 and FIG. 7 is roughly the same in structure as the aforementioned buffer shrapnel discharging end 720 , so it will not be described again in detail.

Compared with the prior art, the cushioning shrapnel loading and unloading mechanism provided by the utility model uses the clamping block 722b to hold on the inner surface of the two elastic support feet a11 of the buffering shrapnel a10, and the two clamping claws 722a hold to the buffering shrapnel The outer surfaces of the two elastic supporting feet a11 of the a10 are thus reliably limited by the buffer elastic piece a10 through the cooperation of the locking block 722b and the two clamping claws 722a.

What is disclosed above is only the preferred embodiment of the present utility model, and of course the scope of rights of the present utility model cannot be limited with this. Therefore, the equivalent changes made according to the patent scope of the utility model still belong to the scope covered by the utility model .
