Description

Technical Field

[0001] The utility model relates to the field of mechanical manufacturing, in particular to a clamp used for expanding the function of a feeder of a full-automatic placement machine. Background Art

[0002] In the process of clamping the tape of the fully automatic placement machine, a feeder is needed to clamp the tape of the components, and the width of the feeder of the placement machine must be consistent with the width of the component tape. However, when clamping the component tape, when the number of small-sized feeders cannot meet the production needs, manual placement can only be used, which reduces production efficiency. If the small-sized tape material is installed in a large-sized feeder, two problems will arise in the placement process: one is the offset of the component tape, and the other is that the component tape is suspended. The offset of the component tape will cause the placement head to be unable to pick up the components at the preset position. The suspension of the component tape will cause the tape to vibrate when picking up the material, destroying the regular arrangement of the components in the tape, and even vibrating the tape out, resulting in failure to pick up the material. Therefore, it is necessary to design a feeder fixture to solve the above-mentioned offset and suspension problems.

[0003] After searching, in the prior art, the Chinese patent with patent application number CN201620632856.5 discloses "a fixture for expanding the function of the feeder of a fully automatic placement machine, comprising a body, the cross section of the body is an L-shaped structure, and the upper and lower steps of the L-shape are respectively a limit body and a support body, the right end of the limit body extends to the right side of the support body, the extended end of the limit body is provided with a card slot connected to the feeder, and the body is integrally carded in the feeder. The utility model manufactures the fixture according to the structural dimensions of the feeder and card-mounts it in the feeder, so that Small-sized component tapes are installed in large-sized feeders for automatic placement, which expands the function of the feeder, saves the purchase cost of the feeder, and increases the use range of the feeder; during the placement process, the component tape will not deviate or vibrate, and the reliability is high; the structure is simple, no screws or nuts are required, and it can be easily installed on the feeder. However, there are still the following defects: there is a lack of buffer mechanism when supporting the tape, which is not conducive to ensuring the stability of the tape feeding when the tape is impacted, and it cannot adapt to the conveying of tapes of different specifications, and the applicability is poor.

[0004] Therefore, we make improvements on this and propose a fixture for expanding the function of the feeder of the fully automatic placement machine. Utility Model Content

[0044] A rotating shaft 40, the rotating shaft 40 is rotatably connected to the inner wall of the frame 10;

[0045] The winding drum 50 is fixedly mounted on the top inner wall of the frame 10, and a groove is formed on the outer wall of the winding drum 50;

[0046] in,

[0047] The rotating shaft 40 passes through the winding drum 50;

[0048] A support portion 60, the support portion 60 is wound on the rotating shaft 40 located in the winding drum 50, and one end of the support portion 60 away from the rotating shaft 40 extends outward through the slot to support the component strip;

[0049] An auxiliary winding assembly 70, which is mounted at the end of the rotating shaft 40 and is used for auxiliary winding;

[0050] A positioning rod 80, the positioning rod 80 is fixedly mounted on one end of the support portion 60 passing through the slot;

[0051] The distance adjustment component 90 is installed between the positioning rod 80 and the inner wall of the frame 10 .

[0052] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the clamping block 30 is an L-shaped structure, and the clamping block 30 and the limiting plate 20 are integrally formed.

When the distance between the positioning rod 80 and the winding drum 50 becomes smaller, the tightened torsion spring 720 rebounds, driving the reset plate 710 to rotate, and the distance between the positioning rod 80 and the winding drum 50 becomes larger, and the support part 60 extends out from the slot of the winding drum 50. At this time, the torsion spring 720 is tightened.

The hand 980 drives the screw rod 910 to rotate, thereby driving the first threaded seat 920 and the second threaded seat 930 to move closer to or away from each other along the sliding rod 940. When the first threaded seat 920 and the second threaded seat 930 move away from each other, the distance between the positioning rod 80 and the winding drum 50 becomes larger, and the extended support portion 60 can adapt to the conveying function of large-sized material strips.

[0059] Specifically, when the clamp for expanding the function of the feeder of the fully automatic placement machine is used: first, the distance between the positioning rod 80 and the take-up drum 50 is adjusted according to the width of the component tape, so that the length of the extended support portion 60 is the same as the width of the component tape. Specifically, the screw rod 910 is driven to rotate by rotating the handle 980, and then the first threaded seat 920 and the second threaded seat 930 are driven to move closer to or away from each other along the sliding rod 940. When the first threaded seat 920 and the second threaded seat 930 move away from each other, the distance between the positioning rod 80 and the take-up drum 50 becomes larger, and the support portion 60 extends out from the slot of the take-up drum 50. At this time, the torsion spring 720 is tightened, and the extended support portion 60 can adapt to the conveying function of large-size tapes. When the first threaded seat 920 and the second threaded seat 930 approach each other, the distance between the positioning rod 80 and the winding drum 50 becomes smaller, and the tightened torsion spring 720 rebounds, driving the reset plate 710 to rotate, and then driving the rotating shaft 40 to retract the support part 60 in the retracted winding drum 50. The remaining support part 60 can adapt to the conveying function of small-sized material belts. After adjusting the extended length of the support part 60, the frame 10 and the limit plate 20 on the device body are clamped on the feeder through the clamping plate 30, and then the component material belt is constrained by the limit plate 20, and guided and supported by the support part 60, thereby realizing the expansion of the feeder function, and when the material belt is subjected to external force during the feeding process, it can be buffered by the torsion spring, thereby improving the stability of use.

[0060] All technical features in this embodiment can be freely combined according to actual needs.

[0061] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
