Description

Technical Field

[0001] This invention relates to the field of automated production equipment, and in particular to an automatic feeding tape peeling fixture. Background Technology

[0002] In the production and processing of tapes, it is often necessary to peel the tape from its release paper so that the tape can be subsequently bonded to the target workpiece.

[0003] Existing tape peeling processes mostly rely on manual labor or semi-automated equipment: When manually feeding, the rolled material needs to be fixed to the support manually, which is not only inefficient, but also prone to material deviation due to uneven operating force; during the feeding process, because the release paper is thin, manual or simple mechanical traction is prone to "slipping" or "tearing" problems, causing the subsequent peeling process to be interrupted; in the peeling stage, manual peeling is prone to problems such as tape residue and release paper damage, affecting product quality.

[0004] When using semi-automated equipment, the functions of "picking up, feeding, guiding, and stripping" are implemented by independent equipment. Materials need to be manually transferred between the independent equipment or rely on complex transition mechanisms. The "waiting time between equipment" accounts for a long proportion in a single production process, the overall production cycle cannot be improved, the efficiency of process connection is low, the coordination is poor, and the overall production efficiency is reduced. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide an automatic feeding tape peeling fixture that integrates multiple processes of "picking up, feeding, feeding and peeling" into the same fixture device, so as to realize the whole process without manual intervention and the coordinated control of parameters of each process. This solves the core problems such as low connection efficiency, large positioning error and poor coordination of manual operation or decentralized equipment, and ensures product quality.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] An automatic tape peeling fixture includes a picking component, a feeding component, a guiding component, and a tape peeling component. The picking component includes a fixture body and a fixture body air shaft, which is slidably mounted on the fixture body for inserting into the core of the material to be pulled to tighten and pick up the material. The feeding component is mounted on the fixture body for placing the material to be pulled into the main feed area of ​​the main line. The guiding component includes a negative pressure adsorption body, which is mounted on the fixture body and adjacent to the feeding component for adsorbing the release paper of the tape on the material, thereby pulling the material to the tape peeling area of ​​the main line. The tape peeling component is disposed on the negative pressure adsorption body for peeling the tape off the material.

[0008] Furthermore, the material feeding assembly also includes a contact plate, the negative pressure adsorption body is provided with a vacuum chamber, the contact plate covers the bottom of the vacuum chamber and is used to adhere the release paper of the tape, the contact plate is evenly distributed with a plurality of suction cup holes, the suction cup holes are connected to the vacuum chamber and are used to transfer the negative pressure of the vacuum chamber to the surface of the release paper, thereby adsorbing the release paper.

[0009] Furthermore, the vacuum chamber is a plurality of segmented vacuum chambers that are not interconnected, and each segment is connected to the suction cup hole to accommodate materials of different widths.

[0010] Furthermore, the material handling assembly also includes a sliding shaft and a linear bearing seat. The linear bearing seat is mounted on the clamp body, and the sliding shaft is slidably mounted on the linear bearing seat. The air expansion shaft of the clamp body is sleeved outside the sliding shaft and is used to extend into the core of the material to be pulled in order to tighten and pick up the material.

[0011] Furthermore, the feeding assembly includes a servo electric cylinder, a connecting plate, and a pusher plate. The connecting plate is installed at the end of the servo electric cylinder and fixedly connected to the pusher plate. The pusher plate is sleeved on the outside of the air shaft of the fixture body. The main production line also includes a main air shaft, a limiting ring, and a bearing seat. The main air shaft is located in the main feeding area and installed on the bearing seat. The limiting ring is installed on the main air shaft and is used to limit the material to be pulled. The servo electric cylinder drives the pusher plate and drives the material to move along the axial direction of the air shaft of the fixture body. The axial directions of the main air shaft and the air shaft of the fixture body are on the same straight line.

[0012] Furthermore, the tape peeling assembly includes a cylinder and peeling grippers. The cylinder is mounted on the negative pressure adsorption body. One end of the peeling gripper is hinged to the output shaft of the cylinder, and the other end is hinged to the negative pressure adsorption body. The peeling gripper has a clamping part, and a clamping area is formed between the clamping part and the negative pressure adsorption body. The clamping area is used to accommodate the release paper of the tape. The cylinder drives the peeling gripper to rotate to clamp the release paper of the tape, and the release paper is peeled off by a robotic arm.

[0013] Furthermore, the automatic feeding tape peeling fixture also includes pneumatic grippers, which are mounted on the fixture body and are used to clamp the core left on the main air shaft to the waste recycling box.

[0014] Furthermore, the top of the clamp body is provided with a connecting part for connecting with the robotic arm. The pneumatic gripper and the clamp body air expansion shaft are located on opposite sides of the clamp body. The negative pressure adsorption body is installed on the side of the clamp body and is located between the pneumatic gripper and the clamp body air expansion shaft.

[0015] Furthermore, the automatic feeding tape peeling fixture also includes a camera, which is mounted on the fixture body and located on the same side as the pneumatic gripper. The camera is used to detect whether the material is pulled to the tape peeling area and to send a position signal to an external control system to trigger the tape peeling assembly to operate.

[0016] Compared with existing technologies, the automatic tape peeling fixture of the present invention has the following advantages:

[0017] (1) This application integrates multiple processes of "material picking-feeding-guiding-stripping" into the same fixture device, realizing no manual intervention in the whole process and coordinated control of parameters of each process, so as to solve the core problems such as low connection efficiency, large positioning error and poor coordination of manual operation or decentralized equipment, and improve production efficiency.

[0018] (2) This application divides the vacuum chamber inside the adsorption body into three independent sections, and opens the vacuum system of the corresponding section as needed, so that the suction cup hole of the section generates negative pressure. By using the "internal and external air pressure difference", materials of different widths are firmly adsorbed onto the contact plate, so as to achieve flexible adaptation and stable adsorption of "narrow, medium and wide" materials.

In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Figures 1-9 The automatic feeding tape peeling fixture 30 of the present invention includes a material picking component 31, a feeding component 32, a feeding component 33, and a tape peeling component 34.

[0042] In this embodiment:

[0043] like Figure 10 As shown, the main production line 40 includes a main feeding area 41, a tape peeling area 42, a negative pressure suction plate 43, a main line air shaft 44, a limit retaining ring 45, and a bearing seat 46.

[0044] The negative pressure suction plate 43 is located on one side of the tape peeling area 42 and is used to adsorb and fix the material after traction so that the tape 73 can be peeled off later.

[0045] The main air shaft 44 is located in the main machine loading area 41 and is mounted on the bearing seat 46.

[0046] The limiting ring 45 is installed on the main line air shaft 44 and is used to limit the material to be pulled.

[0047] The material handling assembly 31 is used to pick up a material to be pulled on the pallet. The material handling assembly 31 includes a clamp body 311, a clamp body air shaft 312, a sliding shaft 313, and a linear bearing seat 314.

[0048] The linear bearing housing 314 is mounted on the clamp body 311, the sliding shaft 313 is slidably mounted on the linear bearing housing 314, and the clamp body air expansion shaft 312 is sleeved on the outside of the sliding shaft 313 for extending into the core 71 of the material to be pulled in order to tighten and pick up the material.

[0049] like Figure 4-5As shown, the feeding assembly 32 is used to place the material to be pulled into the host loading area 41. The feeding assembly 32 includes a servo electric cylinder 321, a connecting plate 322, and a pusher plate 323.

[0050] The connecting plate 322 is installed at the end of the servo electric cylinder 321 and is fixedly connected to the pusher plate 323, which is sleeved on the outside of the air shaft 312 of the fixture body.

[0051] The servo electric cylinder 321 drives the pusher plate 323 and moves the material along the axis of the clamp body air expansion shaft 312 to transfer the material to the main machine loading area 41. At this time, the axes of the main air expansion shaft 44 and the clamp body air expansion shaft 312 are on the same straight line.

[0052] like Figure 6-8 As shown, the material feeding assembly 33 is used to guide the material to be pulled to the tape peeling area 42. The material feeding assembly 33 includes a negative pressure adsorption body 331 and a contact plate 332.

[0053] The negative pressure adsorption body 331 is installed on the clamp body 311. The negative pressure adsorption body 331 is provided with a vacuum chamber 3311. The contact plate 332 covers the bottom of the vacuum chamber 3311 and is used to adhere the release paper 731 of the adhesive tape 73. Multiple suction cup holes 3321 are evenly distributed on the contact plate 332. The suction cup holes 3321 are connected to the vacuum chamber 3311 and are used to transfer the negative pressure of the vacuum chamber 3311 to the surface of the release paper 731, thereby adsorbing the release paper 731.

[0054] In this embodiment, the vacuum chamber 3311 consists of multiple segmented vacuum chambers 3311 that are not interconnected and are independently controlled. The corresponding segment is selected according to the width of the material to avoid most of the suction cup holes 3321 being exposed to the air when adsorbing narrow materials, which would continuously leak negative pressure, resulting in insufficient negative pressure and insufficient suction (materials are easy to fall off). When adsorbing wide materials, if the suction is concentrated in a local area, it will cause uneven force on the material and deformation.

[0055] like Figure 9 As shown, the tape peeling assembly 34 is used to peel the tape 73 of the material. The peeling assembly includes a cylinder 342 and peeling grippers 341.

[0056] The cylinder 342 is mounted on the negative pressure adsorption body 331. One end of the peeling gripper 341 is hinged to the output shaft of the cylinder 342, and the other end is hinged to the negative pressure adsorption body 331 through the pin 343. The peeling gripper 341 is provided with a clamping part 3411. A clamping area is formed between the clamping part 3411 and the negative pressure adsorption body 331. The clamping area is used to accommodate the release paper 731 of the tape 73. The cylinder 342 drives the peeling gripper 341 to rotate to clamp the release paper 731 of the tape 73, and drives the clamp to move through the mechanical arm, thereby peeling off the release paper 731.

[0057] The pneumatic gripper 35 is mounted on the clamp body 311 and is used to clamp and send the core 71 left on the main air shaft 44 to the waste recycling box.

[0058] The camera 36 is mounted on the clamp body 311 and is located on the same side as the pneumatic gripper 35. It is used to detect whether the material is pulled to the tape peeling area 42 and to send a position signal to the external control system to trigger the tape peeling assembly 34 to operate.

[0059] In this embodiment, the top of the clamp body 311 is provided with a connecting part for connecting with a robotic arm. The pneumatic gripper 35 and the clamp body air expansion shaft 312 are located on opposite sides of the clamp body 311. The negative pressure adsorption body 331 is installed on the side of the clamp body 311 and is located between the pneumatic gripper 35 and the clamp body air expansion shaft 312. The clamp has a reasonable overall layout, compact structure, small size, and low manufacturing cost.

[0060] In this application, the roll material 70 is a raw material for the production of absorbent articles, including a core 71, a material roll 72, and an adhesive tape 73. The adhesive layer 732 of the adhesive tape 73 is in direct contact with the material layer, and the release paper 731 covers the adhesive layer 732 and extends to the outside of the material roll 72.

[0061] The workflow for this application is as follows:

[0062] The clamp body air shaft 312 extends into the core 71 of the material to be pulled to tighten and pick up the material, and the clamp and the material are transferred to the main machine loading area 41 by the robotic arm.

[0063] Servo electric cylinder 321 drives pusher plate 323 and drives material to move along the axis of clamp body air expansion shaft 312. When limit stop ring 45 contacts material, it means that material is placed in place on main air expansion shaft 44.

[0064] The negative pressure adsorption body 331 adsorbs the release paper 731 of the adhesive tape 73 on the material, and the main production line 40 pulls one end of the material to the tape peeling area 42.

[0065] The negative pressure suction plate 43 adsorbs and fixes the material after traction, the cylinder 342 drives the peeling claw 341 to rotate to clamp the release paper 731 of the tape 73, and the mechanical arm drives the clamp to move, thereby peeling off the release paper 731.

[0066] This application integrates multiple processes of "material picking-feeding-guiding-peeling" into a single clamping device, achieving a fully automated process with no manual intervention and coordinated controllable parameters for each process. This addresses core issues such as low efficiency, large positioning errors, and poor coordination in manual operation or decentralized equipment, thereby improving production efficiency and ensuring product quality. Furthermore, this application divides the vacuum chamber 3311 within the adsorption body into three independent sections. The vacuum system of the corresponding section is activated as needed, creating negative pressure in the suction cup holes 3321 of that section. Utilizing the "internal and external pressure difference," materials of different widths are firmly adsorbed onto the contact plate 332, achieving flexible adaptation and stable adsorption of narrow, medium, and wide materials. The overall layout of this application is reasonable, the structure is compact, the volume is small, and the manufacturing cost is low.

[0067] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
