Abstract
Description
Technical Field
[0001] This utility model relates to the field of adhesive tape equipment technology, and in particular to a device for wrapping adhesive tape with fine thread. Background Technology
[0002] In the field of electronics manufacturing, especially in the production of assemblies involving the welding of fine wires and electronic components (such as resistors, capacitors, and inductors), reliable insulation of welded joints or component leads is a critical process. Traditional insulation methods include injection molding, heat shrink tubing, or wrapping with insulating tape. Among these, the use of high-temperature adhesive tape for tight wrapping is widely used in the processing of internal wiring harnesses for various consumer electronics, automotive electronics, and communication equipment due to its low cost, simple process, and ability to meet miniaturization requirements. This process not only requires the adhesive tape to completely cover the metal conductor to prevent short circuits, but also requires the outer diameter of the wrapped material to be as small as possible and the shape to be regular to facilitate subsequent assembly processes (such as passing through narrow steel pipes or plastic sleeves).
[0003] Currently, the tape wrapping of thin wire joints largely relies on manual operation. Operators first cut the tape roll into small sections, then manually wrap the tape around the wire joint, twisting it tightly to ensure adhesion. This traditional manual method has several inherent technical drawbacks: First, because the applied force and number of wraps are difficult to control precisely, the tightness and consistency of the wrapping vary between different products, easily resulting in wrapping that is too loose (the tape easily comes off) or too tight (damaging the wire). Second, the starting and ending positions of the manually wrapped tape are random, making it difficult to precisely control the wrapping length and symmetry, easily leading to irregular shapes and localized bulges after wrapping, increasing the outer diameter of the product. This can easily cause jamming or failure to pass through steel pipes with very small inner diameters later on. Utility Model Content
[0004] The purpose of this invention is to provide a device for wrapping adhesive paper with fine thread, which can overcome the shortcomings of the prior art.
[0005] To achieve the above objectives, a fine-thread adhesive tape wrapping device is provided, comprising a frame body, characterized in that the frame body is provided with: a workpiece conveying module for sequentially conveying workpieces to a wrapping station; an adhesive tape processing module for providing, pulling, cutting to a fixed length, and transferring adhesive tape to the wrapping station; and a wrapping forming module, disposed at the wrapping station, for receiving workpieces and adhesive tape and performing a wrapping action; the workpiece conveying module, adhesive tape processing module, and wrapping forming module are sequentially connected and controlled collaboratively by an electrical control system.
[0006] According to the aforementioned fine thread wrapping adhesive tape device, the workpiece conveying module includes: a thread feeding platform, which is provided with guide rails for arranging workpieces; The positioning sheet metal is set at the discharge end of the feeding platform. Its upper part is provided with a positioning slot that matches the shape of the workpiece. This structure realizes the orderly queuing and initial positioning of the workpiece, laying the foundation for subsequent precise transmission. It effectively prevents the workpiece from getting tangled, misaligned or piled up during the transportation process, ensuring the continuity and stability of production.
[0007] According to the aforementioned fine-thread tape wrapping device, the positioning sheet metal is connected to a linear drive mechanism and can reciprocate along the workpiece conveying direction to accurately transfer the workpiece from the receiving position to the wrapping position on the wrapping forming module. The movable positioning sheet metal ensures precise positioning and transmission, ensuring that each workpiece can be accurately placed on the tape at the wrapping station, eliminating the positional error of manual placement. This is the key to ensuring accurate tape wrapping position and high yield.
[0008] According to the aforementioned thin-thread adhesive tape wrapping device, the adhesive tape processing module includes: an adhesive tape tension shaft for mounting the adhesive tape roll and providing feeding tension; an adhesive tape puller, mounted on a sliding plate and driven by a first drive component to clamp and pull out a fixed length of adhesive tape; and a cutter holder equipped with a blade and a second drive component for cutting the adhesive tape at a preset position. This structure achieves automatic, fixed-length feeding and cutting of the adhesive tape. The adhesive tape tension shaft ensures flat and non-loose feeding; the combined action of the adhesive tape puller and the cutter precisely controls the length of each section of adhesive tape, avoiding waste and ensuring the uniformity of material used in each wrapping, thus providing a prerequisite for high-quality wrapping.
[0009] According to the aforementioned fine-thread wrapping adhesive tape device, the adhesive tape processing module further includes a flexible adhesive suction plate. The flexible adhesive suction plate is connected to a third driving component and is equipped with a negative pressure adsorption structure for adsorbing the cut adhesive tape and transferring it to the wrapping and forming module. By adopting a negative pressure adsorption transfer method, lightweight and soft adhesive tape can be picked up and transferred gently and reliably, avoiding wrinkles or drifting, and ensuring that the adhesive tape is placed flat on the lower wrapping board, which is crucial for the subsequent wrapping quality.
[0010] According to the aforementioned fine-thread wrapping adhesive tape device, the wrapping and forming module includes an upper adhesive tape board and a lower adhesive tape board that cooperate with each other; the upper adhesive tape board is connected to a lifting drive component and can perform vertical pressing motion; the upper adhesive tape board and / or the lower adhesive tape board are connected to a rubbing drive component and can perform horizontal reciprocating rubbing motion. The pressing motion ensures the initial adhesion between the adhesive tape and the workpiece, while the rubbing motion simulates the effect of manual rolling, applying uniform pressure to make the adhesive tape tightly and flatly wrapped around the workpiece. The resulting wrapping layer has a small outer diameter and high compactness, greatly improving product quality and the pass rate of subsequent processes.
[0011] According to the aforementioned fine-thread wrapping adhesive tape device, the lower adhesive-rolling board is fixedly installed on the main frame, and the upper adhesive-rolling board is driven by the lifting drive component to achieve pressing and releasing, and is driven by the rubbing drive component to rub along the workpiece axis. The combined motion of the upper board achieves efficient wrapping action, while the structure is simple and easy to control and maintain.
[0012] According to the aforementioned thin thread wrapping adhesive tape device, the device further includes a material collection basin disposed below the wrapping and forming module, used to receive the material that automatically falls off after wrapping is completed.
[0013] This utility model has the following beneficial effects: 1. Compared with existing technologies, this utility model completely replaces the traditional, inefficient manual wrapping method through the coordinated and automated operation of three major modules: workpiece conveying, adhesive paper processing, and wrapping and forming. The equipment can achieve continuous and uninterrupted production, with a short single-piece operation cycle, significantly improving production efficiency.
[0014] 2. Compared with existing technologies, this utility model has made targeted designs in key aspects to address the fragile nature of micro electronic components and thin wires. For example, a flexible adhesive suction plate is used to transfer the adhesive paper by adsorbing it with negative pressure, avoiding the deformation of the adhesive paper or impact on the components that may be caused by mechanical clamping; during the wrapping process, the pressure and rubbing force are precisely calculated and adjusted to ensure that the adhesive paper adheres tightly without damaging the wires or component leads.

[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0018] Reference Figure 1-4 This utility model provides a device for wrapping adhesive tape with fine wire, which is used to automatically wrap high-temperature adhesive tape tightly around a fine wire connector (hereinafter referred to as the workpiece) to which electronic components are soldered.
[0019] The equipment uses the main frame 8 as its basic support structure. On the main frame 8, there are workpiece conveying modules, adhesive paper processing modules, and wrapping and forming modules arranged in the process flow sequence. Each module is controlled by an electrical control system (such as a PLC) to achieve automated continuous production.
[0020] The workpiece conveying module is responsible for sequentially and accurately conveying workpieces to the wrapping station. It mainly includes a wire feeding platform 1 and a positioning sheet metal unit 2. The wire feeding platform 1 is fixedly installed at the beginning of the frame and is equipped with guide rails for arranging workpieces. The positioning sheet metal unit 2 is located downstream of the wire feeding platform 1 and is connected to a sliding cylinder via a mounting plate. Its upper surface is machined with positioning slots that match the shape of the workpiece. The sliding cylinder drives the positioning sheet metal unit 2 to precisely reciprocate between the receiving position and the wrapping position, completing the receiving and precise transfer of the workpiece.
[0021] The adhesive tape handling module is responsible for feeding, pulling out to a fixed length, cutting, and transferring the adhesive tape. It mainly includes an adhesive tape tension shaft 6, an adhesive tape clamp 3, a cutter holder 4, and a flexible adhesive suction plate 5. The adhesive tape tension shaft 6 is mounted via a bearing housing, providing constant feeding tension. The adhesive tape clamp 3 consists of a pneumatic finger and a linear slide, used to clamp and pull out a fixed length of adhesive tape. The cutter holder 4 is equipped with a cylinder-driven blade for cutting the adhesive tape. The flexible adhesive suction plate 5 is driven by a drive unit and can generate negative pressure to attract and transfer the cut adhesive tape onto the lower adhesive tape sheet 7.
[0022] The wrapping and forming module is the core component for performing the wrapping action, mainly consisting of an upper and lower adhesive-wrapping board 7 that work together. The lower adhesive-wrapping board 7 is fixedly installed. The upper adhesive-wrapping board is connected to a lifting cylinder, allowing for vertical pressing motion. Simultaneously, the entire upper board assembly is mounted on a rubbing cylinder, enabling horizontal reciprocating rubbing along the workpiece axis. A collection basin is located below the module to receive the finished product.
[0023] The working principle is briefly described as follows: After the workpiece is arranged on the laying platform 1, it is pushed to the positioning sheet metal 2, which then transfers it to the lower adhesive strip 7, which has been covered with adhesive paper. The adhesive paper clamp 3 pulls out a fixed length of adhesive paper, which is then cut by the cutter and transferred to the lower adhesive strip 7 by the flexible adhesive suction plate 5. The upper adhesive strip presses down on the workpiece and the adhesive paper, and then reciprocates to complete a tight wrap. After the wrap is completed, the upper plate opens, and the workpiece automatically falls into the collection basin. All components reset and enter the next cycle.
[0024] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
