Abstract
Description
Technical Field
[0001] This utility model relates to the field of machining, specifically to a transfer tooling for a thin film sleeve. Background Technology
[0002] Thin-film sleeves are elongated tubular structures, typically made of metal or polymer, with wall thicknesses usually in the millimeter or micrometer range, classifying them as precision devices. Thin-film sleeves are widely used in new energy, semiconductor, industrial, and nuclear energy fields. In the new energy sector, they play a crucial role as anode films in batteries. In the semiconductor field, they can be fitted onto the exterior of carriers or trays of unpackaged chips, MEMS, and other electrostatically sensitive devices, providing electrostatic shielding protection by forming a Faraday cage structure. They can also be tightly bonded to the surface of high-power LEDs, laser diodes, or power semiconductor modules, serving as heat sink fin bases or thermal bridges for efficient heat conduction. In industrial lubrication and insulation, some thin-film sleeves are used as packaging for industrial lubricants or as insulating materials to protect mechanical parts or provide insulation. In the printing industry, thin-film sleeves can serve as supports for printed substrates or labels. In medical devices and biomedical applications, thin-film sleeves can be used as packaging materials or for specific applications in medical imaging and diagnostics.
[0003] However, due to their extremely thin walls, membrane sleeves are difficult to withstand direct mechanical clamping forces. Furthermore, their production and usage stations are often located in different workshops or even far apart, posing significant challenges during fixing, transferring, storing, and assembling. They are prone to deformation and damage due to shaking and vibration. Current transfer methods for membrane sleeves mainly include thermal transfer and vacuum adsorption, but both have significant drawbacks: thermal transfer is mostly used for polymer membrane sleeves, where heat is used to partially melt the sleeve and temporarily adhere it to a surface for transfer. However, membrane sleeves with poor heat resistance are prone to uneven thermal stress after localized heating, leading to deformation and failure. Additionally, this method is unsuitable for metal membrane sleeves due to their high melting point. Vacuum adsorption, on the other hand, is difficult to meet the needs of large-scale industrial production due to high equipment costs and complex maintenance. Summary of the Invention
[0004] In response to the work requirements and existing problems in the aforementioned background technology, the inventors have considered and innovated in order to provide a transfer tooling for thin film sleeves, so as to achieve non-destructive and efficient transfer of thin film sleeves.
[0005] To solve the above problems and achieve the above objectives, the present invention adopts the following technical solution:
[0006] A transfer tooling for a thin film sleeve, used in conjunction with a removable adhesive, the transfer tooling comprising:
[0007] The support includes a base and a support rod disposed on the base, the length of the support rod being not less than the length of the film sleeve; the base is used to provide support for the film sleeve when it is transferred or placed after it is inserted into the support rod, and can be bonded and fixed to the bottom of the film sleeve by a removable adhesive.
[0008] The guide sleeve is designed for detachable installation and can be fitted to the top of the support rod. The bottom surface of the guide sleeve can be bonded and fixed to the upper part of the film sleeve with a removable adhesive.
[0009] The magnetic cover, installed above the guide sleeve, can form a magnetic attraction connection between the guide sleeve and the support rod.
[0010] Preferably, the support includes a first bonding platform disposed around the junction of the support rod and the base, the first bonding platform being used to apply a removable adhesive to bond the lower part of the film sleeve.
[0011] Preferably, the guide sleeve is provided with a second bonding platform, which is used to apply a removable adhesive to bond the upper part of the film sleeve.
[0012] Preferably, the guide sleeve has a through hole at its center, and the upper end of the support rod has a magnetic platform. The diameter of the magnetic platform is not greater than the diameter of the through hole, but smaller than the diameter of the support rod. After the support member and the guide sleeve are installed, the magnetic platform can be inserted into the through hole. The diameter of the through hole is smaller than the diameter of the support rod, which can restrict the position of the support member during installation, so that the distance between the guide sleeve and the base after installation is greater than the length of the film sleeve. It also allows the support rod to be smoothly released from the through hole when the magnetic cover is separated and the support rod is released under gravity.
[0013] Preferably, the diameter of the support rod is smaller than the inner diameter of the film sleeve, and the diameters of the base and the guide sleeve are larger than the outer diameter of the film sleeve.
[0014] Preferably, the diameters of the first bonding platform and the second bonding platform are smaller than the inner diameter of the film sleeve, and they are bonded to the inner walls of the upper and lower openings of the film sleeve respectively by a removable adhesive.
[0015] Preferably, the removable adhesive includes water-soluble adhesives, water-sensitive adhesives, hot-melt adhesives, or photodegradable adhesives.
[0016] Preferably, the guide sleeve is made of polytetrafluoroethylene, and the magnetic cover is made of neodymium iron boron permanent magnet.
[0017] Preferably, the transfer fixture further includes a temporary transfer tool, which includes a handle and an adhesive base. The handle is fixedly connected to the adhesive base, and the adhesive base is bonded to the outer surface of the film sleeve by a removable adhesive.
[0018] Preferably, the shape of the adhesive base is an arc with an arc radius not less than or matching the arc radius of the film sleeve.
[0019] The working principle of this utility model is as follows:
[0020] This invention achieves non-destructive transfer of the film sleeve by combining a support component, a guide sleeve, a magnetic cap, and a temporary transfer tool, along with the reversible bonding characteristics of a removable adhesive.
[0021] First, a temporary transfer tool with an arc-shaped adhesive base is used for temporary transfer. A removable adhesive is used to move the film sleeve from the production line to above the support. The arc-shaped adhesive base adheres to the outer surface to prevent stress damage. Next, the bottom of the film sleeve is fixed. A removable adhesive is applied to the first adhesive platform of the support. The film sleeve is then lowered and fitted onto the support rod, bonding its bottom to the first adhesive platform. The adhesive on the temporary transfer tool is then removed. Next, the top is fixed and locked. Adhesive is applied to the second adhesive platform of the guide sleeve. It is then fitted onto the support rod and lowered to the top of the film sleeve, bonding its top to the second adhesive platform. At this point, the magnetic suction platform at the top of the support rod is inserted into the central through-hole of the guide sleeve. A magnetic cap is then placed on the upper surface of the guide sleeve. The magnetic suction platform is attracted, locking the guide sleeve and support together. The support provides load-bearing capacity, and the guide sleeve and support clamp the film sleeve. The magnetic cap ensures structural stability and prevents shaking and deformation.
[0022] When unloading the film sleeve, first make the removable adhesive between the first bonding platform and the film sleeve lose its stickiness, and release the adhesive at one end of the film sleeve. Then, slide the magnetic cover off and remove the support. After that, assemble the guide sleeve and the film sleeve to the target station. Then, remove the removable adhesive between the second bonding platform and the film sleeve to release the adhesive at the other end of the film sleeve.
[0023] The beneficial effects of this utility model are:
[0024] 1. This invention achieves non-destructive transfer and storage of thin-film sleeves. The invention employs a support structure and guide sleeve design, combined with an easily removable adhesive and a magnetic locking mechanism with a magnetic cap, to stably place the thin-film sleeve without shaking. This avoids stress damage to the thin-walled sleeve caused by mechanical clamping and thermal stress deformation problems associated with heat transfer methods, thus achieving non-destructive transfer and storage of the thin-film sleeve.
[0025] 2. This utility model improves transfer efficiency and ease of operation. The detachable connection between the support and the guide sleeve, as well as the magnetic locking of the magnetic cover, facilitates the rapid loading and unloading of the film sleeve, simplifies the operation process, and improves transfer efficiency and ease of operation.
[0026] 3. This invention reduces production costs. Compared to the equipment and maintenance costs required by traditional vacuum adsorption methods, this invention has a simple structure and controllable material and manufacturing costs, significantly reducing production costs.

Detailed Implementation
[0049] The present utility model patent will be further described in detail below with reference to the accompanying drawings and specific embodiments; it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model patent.
[0050] The transfer tooling for this film sleeve needs to be used in conjunction with a suitable removable adhesive 8. The removable adhesive 8 should be able to easily lose its stickiness or be removed by chemical or physical means. The film sleeve 5 can be bonded using a suitable bonding method depending on the removable adhesive 8. For example, when using a water-soluble adhesive, sufficient gaps should be left at the bonding points at both ends of the film sleeve 5 to allow distilled water to seep in, or the bonding points of the film sleeve 5 can be changed to the annular surfaces at the top and bottom. When using a hot melt adhesive, since a hot air gun or infrared heater can heat the film sleeve 5 through it, the bonding point can be chosen to be the inner side of the film sleeve 5.
[0051] Example
[0052] In this embodiment, the target thin film sleeve 5 is applied in the nuclear energy field. The thin film sleeve 5 is made of copper, so hot melt adhesive is selected as the removable adhesive 8. The small amount of hot melt adhesive remaining in the thin film sleeve 5 has no impact on the production process. The mounting flange 6 is installed on the mobile device (existing equipment, not shown in the figure) and can drive the transfer tooling to move up and down. Two ear plates are added to the guide sleeve 2. The ear plates have screw holes in the center. The guide sleeve 2 is installed on the mounting flange 6 with bolts. After the guide sleeve 2 is installed at the corresponding screw hole position of the mounting flange 6, the guide sleeve 2 coincides with the central axis of the assembly workpiece 7, so that the guide sleeve 2 can accurately assemble the thin film sleeve 5 onto the assembly workpiece 7 under the drive of the mounting flange 6.
[0053] like Figure 1 — Figure 14 The invention relates to a transfer fixture for a thin film sleeve, which consists of a support 1, a guide sleeve 2, and a magnetic cap 3.
[0054] like Figure 12 As shown, the support component 1 is the core load-bearing component of this device. The support component 1 is composed of a base 11, a first bonding platform 12, a support rod 13, and a magnetic platform 14 fixedly connected together. The base 11, the first bonding platform 12, the support rod 13, and the magnetic platform 14 are cylindrical structures. The diameter of the first bonding platform 12 is smaller than that of the base 11, the diameter of the support rod 13 is smaller than that of the first bonding platform 12, and the diameter of the magnetic platform 14 is smaller than that of the support rod 13. The magnetic platform 14 is made of cast iron.
[0055] like Figure 2 — Figure 6 , Figure 9 , Figure 12 , Figure 13 As shown, the guide sleeve 2 is detachably connected to the support member 1. The guide sleeve 2 has a through hole 21 in the center. The through hole 21 matches the shape of the support rod 13 and the magnetic platform 14 and is in clearance fit. The support member 1 can be easily removed from the through hole 21. The guide sleeve 2 has a second adhesive platform 22. The guide sleeve 2 is made of polytetrafluoroethylene. The first adhesive platform 12 and the second adhesive platform 22 are used together to fix the film sleeve at both ends by a removable adhesive 8 to prevent the sleeve from shaking or deforming due to lack of positioning.
[0056] like Figure 3 — Figure 6 As shown, the magnetic cover 3 is detachably connected to the support member 1. The magnetic cover 3 is cylindrical in shape and made of neodymium iron boron permanent magnet. It cooperates with the support rod 13 to form a magnetic fixation, thereby fixing and locking the guide sleeve 2 and the thin film sleeve 5.
[0057] like Figure 14As shown, the device also includes a temporary transfer tool 4, which serves as a component for transferring the film sleeve 5 from the production station to this device. The temporary transfer tool 4 consists of a handle 41 and an adhesive base 42, with the handle 41 and the adhesive base 42 fixedly connected. The adhesive base 42 is arc-shaped.
[0058] In summary, the specific usage process of this utility model is as follows:
[0059] First, such as Figure 1 As shown, after the film sleeve 5 is produced, a removable adhesive 8, i.e., hot melt adhesive, is applied to the temporary transfer tool 4 to bond the film sleeve 5 and transfer it above the support member 1; then, the removable adhesive 8 is applied to the first bonding platform 12 of the support member 1, and the film sleeve 5 is moved down and inserted into the support member 1 to the first bonding platform 12, and is bonded to the first bonding platform 12 through the removable adhesive 8. A hot air gun or infrared heater and a silicone scraper are used to make the hot melt adhesive on the temporary transfer tool 4 and the film sleeve 5 lose its stickiness and are gently scraped off.
[0060] Furthermore, such as Figure 2 As shown, after applying the removable adhesive 8 to the second bonding platform 22 of the guide sleeve 2, it moves down and is inserted into the support member 1, so that the upper part of the film sleeve 5 contacts and bonds with the removable adhesive 8 on the second bonding platform 22.
[0061] Furthermore, such as Figure 3 , Figure 4 As shown, the magnetic cap 3 is placed on the upper end face of the guide sleeve 2, so that the magnetic platform 14 of the support member 1 and the magnetic cap 3 form a magnetic attraction connection. At this time, the film sleeve 5 is fixed between the support member 1 and the guide sleeve 2, and can be transferred and stored.
[0062] Furthermore, such as Figure 15 , Figure 16 As shown, this tooling and the diaphragm sleeve 5 are installed on the mounting flange 6 via the guide sleeve 2 and the second locking bolt 24. The mounting flange 6 is located directly above the assembled workpiece 7 and can be raised and lowered.
[0063] Furthermore, such as Figure 17 , Figure 18 As shown, use a hot air gun or infrared heater to remove the adhesive 8 between the first adhesive platform 12 of the support member 1 and the film sleeve 5 to release the adhesion between the film sleeve 5 and the support member 1. Then remove the magnetic cover 3, and the support member 1 will slide out of the guide sleeve 2. Use a tray to pick up and remove the support member 1.
[0064] Furthermore, such as Figure 19As shown, the control device lowers the mounting flange 6 vertically, bringing the lower part of the diaphragm sleeve 5 close to but not in contact with the assembly workpiece 7, and positioning the diaphragm sleeve 5 directly opposite the assembly workpiece 7; the assembly workpiece 7 is as follows... Figure 20 As shown, if necessary, a guide boss is provided at the end of the assembly workpiece 7. The guide boss can be a vertical sleeve or a conical sleeve. During installation, the diaphragm sleeve 5 is first inserted into the guide boss but does not contact the base surface of the assembly workpiece 7 to prevent the diaphragm sleeve 5 from being damaged during the descent process.
[0065] Furthermore, such as Figure 20 , Figure 21 As shown, a hot air gun or infrared heater is used to remove the adhesive 8 between the second bonding platform 22 of the guide sleeve 2 and the film sleeve 5 to release the adhesion of the upper part of the film sleeve 5. The film sleeve 5 slides down and is installed on the assembly workpiece 7 under the action of gravity, completing the assembly and installation. The mounting flange 6 rises and resets to remove the guide sleeve 2.
