Abstract
Description
Technical Field
[0001] This utility model relates to the field of copper foil processing technology, specifically to a tooling for removing defective foil materials. Background Technology
[0002] In the copper foil industry, it is common to manually remove defective foil. There are many types of defects, such as black spots, white spots, and pinholes. Edge defects are visible at the edges, while defects in the roll are known from the point of occurrence (the length of meters from the start of production to the defective point is recorded during production). However, cutting and removing defects from the roll is more difficult. If dealing with a whole roll of waste foil, thick gloves can be worn for protection. But when dealing with usable copper foil, due to the need for precise movements, wearing thick gloves will affect the operation, while thin gloves will not provide good protection. This can lead to workers being cut by the copper foil. If a blade is used to cut directly, it is easy to waste copper foil due to inconsistent cutting layers.
[0003] Therefore, in order to correct the above-mentioned defects, we propose a tooling for rejecting defective foil. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a tooling for rejecting defective foil.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling for removing defective foil, comprising a tool magazine, a cutting tool, and a tool holder. The tool holder is located inside the tool magazine. The tool magazine has openings at both its front and rear ends. The front end of the tool holder extends from the front opening of the tool magazine and connects to the cutting tool. The rear end of the tool holder opens from the rear end of the tool magazine. A toothed plate is fixed to the upper end face of the tool holder. A transmission gear is mounted inside the tool magazine via a bearing at one end. The transmission gear meshes with the fixed toothed plate. A crank handle is mounted outside the tool magazine via a bearing. The crank handle is connected to the transmission gear via a shaft. A locking structure is installed at the rear opening of the tool magazine. The locking structure is used to lock the rear end of the tool holder.
[0006] Furthermore, the locking structure includes a plastic threaded cylinder installed at the end opening of the tool magazine. The plastic threaded cylinder is divided into two parts with a gap, and a nut is connected to the external thread of the plastic threaded cylinder. The end of the tool holder moves through the plastic threaded cylinder.
[0007] Furthermore, the tool magazine has a straight slot parallel to the tool holder, and a scale line parallel to the top of the straight slot is also installed on the tool magazine. An L-shaped connecting rod is slidably connected in the straight slot. One end of the L-shaped connecting rod is fixed to the tool holder, and the other end points to the scale line and is connected to a straight arrow.
[0008] Furthermore, several pressing gears are installed in the tool magazine via bearings, and the pressing gears mesh with the fixed gear plate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] This utility model provides a technical solution:
[0019] Please see Figure 1-4A tooling for removing defective foil includes a tool magazine 1, a cutting tool 2, and a tool holder 3. The tool holder 3 is located inside the tool magazine 1. The tool magazine 1 has openings at both its front and rear ends. The front end of the tool holder 3 extends from the front opening of the tool magazine 1 and connects to the cutting tool 2. The rear end of the tool holder 3 opens from the rear end of the tool magazine 1. A toothed plate 4 is fixed to the upper end face of the tool holder 3. A transmission gear 5 is installed inside the tool magazine 1 via a bearing. The transmission gear 5 meshes with the fixed toothed plate 4. A crank handle 8 is installed outside the tool magazine 1 via a bearing. The crank handle 8 is connected to the transmission gear 5 via a shaft. A locking structure 7 is installed at the rear opening of the tool magazine 1. The locking structure 7 is used to lock the rear end of the tool holder 3.
[0020] The overall length of this fixture is controlled within ten centimeters. The extension length of the blade is controlled by rotating the knob, and the accuracy can be controlled within 0.5mm through gear design.
[0021] When workers need to cut copper foil rolls, the rolls are cylindrical and placed vertically, while the blade chamber 1 is placed horizontally. The extension of the blade 2 is adjusted according to the number of layers or thickness of the copper foil roll to be cut, so that the blade 2 fits against the top of the copper foil roll. Then, the blade chamber 1 is pressed down, so that the blade 2 completes the cut from top to bottom. For example, if the copper foil roll is 10,000 meters long and the diameter of the roll on the core is about 30 centimeters, and three white spots appear at 5,000 meters, then the production department has to discard the copper foil after 5,000 meters. The number of layers or thickness of the cut end in the copper foil roll can be calculated based on the thickness of the copper foil.
[0022] After adjusting the extension of the tool 2, the tool holder 3 needs to be locked using the locking structure 7. The locking structure 7 includes a plastic threaded cylinder 72 installed at the end opening of the tool magazine 1. The plastic threaded cylinder 72 is divided into two parts with a gap, and a nut 71 is connected to the external thread of the plastic threaded cylinder 72. The end of the tool holder 3 moves through the plastic threaded cylinder 72. That is, when the nut 71 is turned to disengage from the plastic threaded cylinder 72, the plastic threaded cylinder 72 can open slightly, thereby loosening the tool holder 3 for adjustment. When the nut 71 is fitted onto the plastic threaded cylinder 72, the plastic threaded cylinder 72 tightly wraps around the tool holder 3, completing the locking.
[0023] Furthermore, a straight groove 10 parallel to the tool holder 3 is provided on the tool magazine 1. A scale line 9 parallel to the top of the straight groove 10 is also installed on the tool magazine 1. An L-shaped connecting rod 11 is slidably connected in the straight groove 10. One end of the L-shaped connecting rod 11 is fixed to the tool holder 3, and the other end points to the scale line 9 and is connected to a straight arrow 12.
[0024] During the cutting process, several pressing gears 6 are installed in the blade chamber 1 through bearings. The pressing gears 6 mesh with the fixed tooth plate 4 and press the blade handle 3. At the same time, the blade handle 3 is supported by the inner bottom of the blade chamber 1. A rubber layer 13 is installed at the front end of the blade chamber 1. The rubber layer 13 also has an opening that is consistent with the front end opening of the blade chamber 1. In this way, the rubber layer 13 replaces the front end of the blade chamber 1 to contact the copper foil roll, preventing damage to the copper foil roll.
[0025] After cutting is complete, the cutting tool 2 can be hidden inside the tool magazine. The opening size at the front end of the tool magazine 1 is larger than the size of the cutting tool 2.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
