Description

Technical Field

[0001] This utility model relates to the field of feeder stripping technology, and in particular to a feeder stripping structure. Background Technology

[0002] In precision manufacturing fields such as electronic components and semiconductor packaging, placement equipment is the core equipment for achieving high-speed, high-precision component placement. Due to the physical limitations of certain special materials (such as inflexibility, fragility, or irregular shape), roll-to-roll feeding methods cannot be used, and sheet feeding systems must be relied upon.

[0003] Existing sheet material feeding technologies typically employ stacking of sheet carrier trays or feeding individual sheets one by one. Conventional methods for peeling off the release liner from the sheet material include mechanical gripper peeling and vacuum nozzle separation. However, in practical applications, these technologies require multiple reciprocating actions to complete a single peel, resulting in long cycle times that are difficult to match with the production pace of high-speed mounting equipment. Utility Model Content

[0004] Based on this, the present invention provides a feeder stripping structure.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted:

[0006] A feeder stripping structure includes:

[0007] The material guiding assembly includes a guide plate, a stripper mounted on one side of the guide plate, a traction roller rotatably mounted below the stripper, and a waste guide box located below the traction roller; and

[0008] A stripping assembly located on one side of the material guiding assembly; the stripping assembly includes a U-shaped bracket, a longitudinal cylinder connected to the bottom of the U-shaped bracket, a pressure plate installed at the top of the U-shaped bracket, a transverse cylinder passing through the middle of the U-shaped bracket, and a pressure roller rotatably installed at one end of the transverse cylinder; the pressure roller and the traction roller are arranged opposite to each other.

[0009] The aforementioned feeder peeling structure is simple in structure and easy to use. The pressure plate and peeling blade work together to bend the blank area of ​​the release paper, while the pressure roller and traction roller pull the release paper, causing the material to peel off from the release paper at the end of the peeling blade. Single peeling can be completed without multiple reciprocating actions, which is simple, fast and effectively improves the production cycle of high-speed mounting equipment.

[0010] In one embodiment, the pressure plate is disposed adjacent to the peeling blade, and the end of the pressure plate near the peeling blade forms a pressing portion.

[0011] In one embodiment, a plurality of partition strips are evenly spaced on the top surface of the pressure plate.

[0012] In one embodiment, optical fibers are also installed on the pressure plate between adjacent separator strips.

[0013] In one embodiment, the material guiding assembly further includes a traction motor mounted on one side of the waste guide box; the traction motor is connected to the traction roller via a synchronous belt.

[0014] In one embodiment, the top of the waste guide box has an opening facing the stripping assembly for the pressure roller to pass through.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0030] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0032] Please see Figures 1 to 8 This invention relates to a feeder peeling structure, comprising a feeder assembly 10 and a peeling assembly 20 located on one side of the feeder assembly 10. Both the feeder assembly 10 and the peeling assembly 20 are installed inside the feeder housing 30. The feeder assembly 10 holds a sheet 40, which includes release paper 41 and multiple materials 42 arrayed on the release paper 41. The length of the release paper 41 is greater than the length of the materials 42; therefore, a blank area 43 is formed at the edge of the release paper 41. The feeder assembly 10 and the peeling assembly 20 cooperate to bend the blank area 43 to facilitate the peeling of the materials 42.

[0033] The material guiding assembly 10 includes a guide plate 11, a peeling blade 12 mounted on one side of the guide plate 11, a traction roller 13 rotatably mounted below the peeling blade 12, a waste guide box 14 located below the traction roller 13, and a traction motor 15 mounted on one side of the waste guide box 14. The traction motor 15 is connected to the traction roller 13 via a synchronous belt 16 to drive the traction roller 13 to rotate. The guide plate 11 and the peeling blade 12 are used to hold the sheet material 30.

[0034] In this embodiment, the top of the waste guide box 14 is provided with an opening 17 facing the stripping assembly 20, and the opening 17 is used for the components of the stripping assembly 20 to enter.

[0035] The peeling assembly 20 includes a U-shaped bracket 21, a longitudinal cylinder 22 connected to the bottom of the U-shaped bracket 21, a pressure plate 23 installed at the top of the U-shaped bracket 21, a transverse cylinder 24 passing through the middle of the U-shaped bracket 21, and a pressure roller 25 rotatably installed at one end of the transverse cylinder 24. The pressure roller 25 is arranged opposite to the traction roller 13. After the pressure roller 25 passes through the through-hole 17, it cooperates with the traction roller 13 to clamp and pull the release paper 41, so as to pull the release paper 41 into the waste guide box 14.

[0036] Specifically, the opposite sides of the U-shaped bracket 21 are slidably connected to the interior of the feeder compartment 30 via guide rail pairs 210. In conjunction with the longitudinal cylinder 22, the pressure plate 23 can be driven downwards to bend the blank area 43. The pressure plate 23 is arranged adjacent to the peeling blade 12, with the end of the pressure plate 23 near the peeling blade 12 forming a pressing section 230. Multiple partition strips 26 are evenly spaced on the top surface of the pressure plate 23. These partition strips 26 press the release paper 41 on the top surface of the peeling blade 12, and the space between adjacent partition strips 26 accommodates material 42 to ensure separation between the materials 42 and prevent mutual interference during the peeling process.

[0037] In this embodiment, an optical fiber 27 is also installed on the pressure plate 23 between adjacent separator strips 26 to detect the presence or absence of material 42.

[0038] Combination Figure 7 and Figure 8 To understand this, in actual operation, the sheet material 40 is placed on the guide plate 11 and the peeling blade 12, with the blank area 43 extending beyond the peeling blade 12. The longitudinal cylinder 22 drives the pressure plate 23 downwards until its top surface is flush with the top surface of the peeling blade 12. The downward pressing part 230 squeezes the blank area 43, causing it to bend downwards along the end of the peeling blade 12 (e.g., ...). Figure 8 (As shown by the dotted line) At this time, the transverse cylinder 24 drives the pressure roller 25 to approach the traction roller 13, so that the blank area 43 is clamped between the pressure roller 25 and the traction roller 13. Then the traction motor 15 starts and pulls the entire release paper 41 downward into the waste guide box 14, so that the material 42 is separated from the release paper 41 at the end of the peeling knife 12. The material 42 then enters the top surface of the pressure plate 23 to be picked up.

[0039] In this embodiment, the end of the peeling blade 12 is provided with a wedge-shaped end face 120 to facilitate the bending of the release paper 41.

[0040] In this embodiment, as Figure 4As shown, the surface of the traction roller 13 is provided with anti-slip teeth, which effectively improves the traction force on the release paper 41 and prevents slippage.

[0041] The above-mentioned feeder peeling structure is simple in structure and easy to use. The pressure plate 23 and the peeling knife 12 work together to bend the blank area 43 of the release paper 41. The pressure roller 25 and the traction roller 13 pull the release paper 41, so that the material 42 is peeled off from the release paper 41 at the end of the peeling knife 12. Single peeling can be completed without multiple reciprocating actions, which is simple and fast and effectively improves the production cycle of high-speed mounting equipment.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
