Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, specifically to cutting equipment. Background Technology

[0002] In the battery manufacturing process, the electrode sheets need to be cut using cutting molds, such as cutting the chamfers of the electrode sheets. The waste material after cutting is usually cleaned up using a vacuum cleaner.

[0003] However, cleaning waste with a vacuum cleaner is difficult and requires regular filter replacement, resulting in a poor user experience. Utility Model Content

[0004] In view of this, the present invention provides a cutting device to solve the problem that the existing cutting molds use a vacuum cleaner to clean waste materials, which is difficult to clean and has a poor user experience.

[0005] This utility model provides a cutting device, including:

[0006] A cutting die, including an upper die and a lower die, is suitable for cutting materials. The lower die is provided with a waste channel that runs through the vertical direction. The inlet of the waste channel is used to receive waste material after cutting.

[0007] A hopper is located below the lower mold. The hopper has a large end and a small end that are arranged opposite to each other. The large end is connected to the outlet of the waste channel.

[0008] The waste box is connected to the small end.

[0009] Beneficial effects: The cutting equipment of this utility model has a waste channel set on the lower mold of the cutting mold. The waste channel is connected to the large end of the hopper, and the small end of the hopper is connected to the waste box. After the cutting mold cuts the material, the waste generated falls into the waste channel under its own weight. The waste is first discharged into the hopper through the waste channel, and then discharged into the waste box for storage after the waste is gathered in the hopper. After a certain amount of waste accumulates in the waste box, it is discharged and cleaned in a unified manner. The cleaning is simple and has a good user experience. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0019] According to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, a cutting device is provided, including: a cutting die 1, a hopper 2, and a waste container 3. The cutting die 1 includes an upper die 101 and a lower die 102, suitable for cutting materials. The lower die 102 is provided with a waste channel 103 extending in a vertical direction, and the inlet of the waste channel 103 is used to receive waste material after cutting. The hopper 2 is located below the lower die 102, and the hopper 2 has a large end 201 and a small end 202 arranged opposite to each other. The large end 201 is connected to the outlet of the waste channel 103. The waste container 3 is connected to the small end 202.

[0020] Therefore, the cutting equipment provided in this embodiment of the present invention has a waste channel 103 on the lower mold 102 of the cutting mold 1. The waste channel 103 is connected to the large end 201 of the hopper 2, and the small end 202 of the hopper 2 is connected to the waste box 3. After the cutting mold 1 cuts the material, the waste generated falls into the waste channel 103 under its own weight. The waste is first discharged into the hopper 2 through the waste channel 103. After the waste is gathered by the hopper 2, it is discharged into the waste box 3 for storage. After a certain amount of waste is accumulated in the waste box 3, it is discharged and cleaned in a unified manner. The cleaning is simple and has a good user experience.

[0021] Specifically, the up and down directions are as follows: Figure 1 As shown by arrow H, the upper mold 101 is located above the lower mold 102. A guide post and a drive mechanism (not shown in the figure) are also provided between the upper mold 101 and the lower mold 102. The drive mechanism drives the upper mold 101 to move up and down along the guide post and cooperate with the lower mold 102 to cut materials, such as cutting the chamfer of the electrode sheet. The drive mechanism can adopt any existing structure, such as a press.

[0022] In addition, the hopper 2 is located directly below the lower mold 102, and the waste box 3 is located directly below the hopper 2. The top of the waste box 3 has a feed inlet. The opening size of the large end 201 of the hopper 2 matches the bottom of the lower mold 102, and the opening size of the small end 202 of the hopper 2 matches the size of the feed inlet. The hopper 2 is used for the transition of waste material between the cutting mold 1 and the waste box 3, achieving compatibility between the two sizes. Since the size of the cutting mold 1 is generally larger than that of the waste box 3, the large end 201 of the hopper 2 is connected to the waste channel 103 on the lower mold 102, and the small end 202 of the hopper 2 is connected to the waste box 3. This embodiment of the utility model can also be applied to various models of cutting mold 1, that is, it expands the scope of application and facilitates promotion.

[0023] To prevent waste from escaping upwards, in one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the cutting equipment also includes an air blowing mechanism 4. An air outlet 401 is provided on the side of the upper mold 101 facing the lower mold 102. The air outlet 401 faces the cutting area, which refers to the area where the cutting edges of the upper mold 101 and lower mold 102 are located, i.e., the area where waste material is formed. The air outlet 401 is connected to the air blowing mechanism 4 and is used to blow the cut waste material towards the inlet of the waste channel 103. After the material is cut, the waste material can immediately enter the waste channel 103 downwards under the influence of the airflow from the air outlet 401 and its own weight, thereby accelerating the falling speed of the waste material, achieving rapid waste removal without stopping the machine, and improving cutting efficiency.

[0024] It should be noted that the cutting gap between the upper die 101 and the lower die 102 is generally small, about 10 micrometers. When punching materials, a vacuum zone is easily formed, causing waste material to escape upwards. This escaped waste material can easily mix with the normal material, affecting the normal processing of the material. In this embodiment of the invention, an air vent 401 is provided on the upper die 101, which can blow the waste material downwards, thereby preventing the waste material from escaping upwards and ensuring the normal processing of the material.

[0025] It should be noted that the present invention does not limit the specific structure of the blowing mechanism 4. Any existing structure can be selected as needed. For example, the blowing mechanism 4 can be in the form of a cylinder pushing a piston to form a downward airflow at the air outlet 401, or the blowing mechanism 4 can be a fan connected to the air outlet 401 through an air pipe to directly form a downward airflow at the air outlet 401.

[0026] Furthermore, this embodiment of the invention does not limit the shape of the air outlet 401; it can be a round hole, an elliptical hole, a strip-shaped hole, etc.

[0027] In one embodiment, such as Figure 3 As shown, the upper mold 101 facing the lower mold 102 is also provided with a movable baffle 402, which is used to block the air outlet 401. By blocking the air outlet 401 with the baffle 402, the air outlet 401 can be protected and foreign objects can be prevented from entering the air outlet 401. In addition, by partially blocking the air outlet 401 with the baffle 402, the airflow intensity can be adjusted and the blowing effect can be improved.

[0028] It should be noted that the present invention does not restrict the movable connection method of the baffle 402. The baffle 402 can be rotatably disposed on the bottom surface of the upper mold 101, or the baffle 402 can be slidably disposed on the bottom surface of the upper mold 101. The baffle 402 can block the air outlet 401, or the baffle 402 can be moved to expose the air outlet 401.

[0029] For example, an installation groove is provided at the bottom of the upper mold 101, and both the baffle 402 and the air outlet 401 are provided in the installation groove to avoid the baffle 402 affecting the cutting operation. The baffle 402 is rotatably provided in the installation groove via a pivot. When air needs to be blown through the air outlet 401, the baffle 402 is rotated to expose the air outlet 401. When air does not need to be blown through the air outlet 401, the baffle 402 is rotated to block the air outlet 401.

[0030] In one embodiment, the cutting device further includes a switch (not shown) electrically connected to the air blowing mechanism 4, used to turn on the air blowing mechanism 4 to form a downward airflow at the air outlet 401, or to turn off the air blowing mechanism 4. By controlling the opening and closing of the air blowing mechanism 4 by the switch, air blowing can be turned on only when necessary, thus saving energy.

[0031] Furthermore, in one embodiment, the switch is adapted to activate the air blowing mechanism 4 when the cutting die 1 is cutting the material. The air blowing mechanism 4 is activated when the cutting die 1 is cutting the material to blow air, and is closed under other circumstances to ensure that the airflow is concentrated on the waste material and to avoid the airflow affecting the normal operation of the material.

[0032] In one embodiment, such as Figure 1 and Figure 2 As shown, the cutting equipment also includes a negative pressure mechanism (not shown in the figure), and the waste box 3 is connected to the negative pressure mechanism through the negative pressure pipeline 5. The negative pressure mechanism can create negative pressure in the waste box 3 through the negative pressure pipeline 5 and create suction at the inlet of the waste channel 103, so that the waste is sucked into the waste box 3 through the waste channel 103 under the action of negative pressure.

[0033] Specifically, the waste box 3 and the waste channel 103 need to be sealed to prevent negative pressure leakage. The waste box 3 has a mounting hole on its side, one end of the negative pressure pipeline 5 is connected to the mounting hole, and the other end is connected to the negative pressure mechanism.

[0034] It should be noted that the present invention does not limit the specific structure of the negative pressure mechanism. Any existing structure can be selected as needed. For example, the negative pressure mechanism can be a negative pressure fan.

[0035] To prevent the material from being affected by negative pressure suction and rubbing against the cutting mold 1, thus causing scratching, in one embodiment, as follows... Figure 1 As shown, the side wall of the hopper 2 is provided with an air inlet 6. By providing an air inlet 6 on the side wall of the hopper 2, the vacuum zone formed by the negative pressure can be counteracted, thus solving the problem of material scraping. Moreover, the air intake at the air inlet 6 can also prevent material from escaping from the air inlet 6.

[0036] It is understood that the present invention does not limit the number of air inlets 6, and may select one, two or more, nor does it limit the shape of the air inlets 6, which may be round, elliptical, strip-shaped, etc.

[0037] Furthermore, the negative pressure mechanism is electrically connected to a switch, which controls the negative pressure mechanism and the air blowing mechanism 4 to open synchronously, thereby further saving energy. To ensure that the material can be sucked into the waste box 3, the air blowing mechanism 4 and the negative pressure mechanism can be delayed in closing after the material is cut.

[0038] In one embodiment, the waste bin 3 is equipped with a storage ventilated bag (not shown in the figure). The storage ventilated bag is ventilated to allow airflow and create negative pressure suction. The top of the storage ventilated bag has an inlet that connects to the small end 202. The storage ventilated bag can be a mesh bag, a perforated plastic bag, etc. After the waste is sucked into the waste channel 103, it first enters the hopper 2, where it is collected and then enters the storage ventilated bag for unified storage. Once a certain amount is stored, only the storage ventilated bag needs to be replaced, or the bag can be disassembled to discharge the waste and then reinstalled, thus achieving continuous waste cleaning. The structure is simple and easy to use.

[0039] Furthermore, in one embodiment, the waste container 3 is provided with an openable and closable door or top cover (not shown in the figure). By opening the door or top cover, the storage breathable bag can be removed from the waste container 3, or the storage breathable bag can be placed in the waste container 3, thereby facilitating the discharge of waste from the storage breathable bag.

[0040] Furthermore, in one embodiment, a weighing scale is provided at the bottom of the waste box 3. The weighing scale is used to weigh the waste. When the weighing scale reaches a certain value, it is determined that the waste stored in the breathable bag needs to be discharged.

[0041] In some other embodiments, the waste box 3 has a transparent window on its side, through which the operator can observe the waste volume in the storage breathable bag. When the waste fills the storage breathable bag, the storage breathable bag is removed from the waste box 3 and the waste in the storage breathable bag is discharged, so as to achieve timely cleaning of the waste.

[0042] In one embodiment, the bottom surface of the upper mold 101 is provided with an upper cutting edge, and the top surface of the lower mold 102 is provided with a corresponding lower cutting edge. The inlet of the waste channel 103 is located near the lower cutting edge. The upper and lower cutting edges work together to cut the material, and the inlet of the waste channel 103 is located near the lower cutting edge so that the waste material can quickly enter the waste channel 103.

[0043] The working principle of this utility model embodiment is as follows:

[0044] The material is pre-transported between the upper mold 101 and the lower mold 102, with the part to be cut corresponding to the upper and lower cutting edges. The baffle 402 is rotated to expose the air outlet 401. The upper mold 101 of the cutting mold 1 moves downwards along the guide column under the drive mechanism. When the upper mold 101 reaches its lowest point, the upper and lower cutting edges work together to cut the material. Simultaneously, a switch is triggered, controlling the air blowing mechanism 4 and the negative pressure mechanism to start. The air blowing mechanism 4 creates airflow at the air outlet 401, blowing the waste material towards the inlet of the waste channel 103. The negative pressure mechanism creates negative pressure at the inlet of the waste channel 103, drawing the waste material into the waste channel 103. After being collected and gathered by the hopper 2, the waste material is sucked into the storage ventilated bag in the waste box 3. Additionally, air enters through the air inlet 6 on the side of the hopper 2, counteracting the vacuum created by the negative pressure and preventing material scraping.

[0045] After the waste in the storage breathable bag has been collected to a preset amount, open the door to discharge the waste from the storage breathable bag. Then, reinstall the empty storage breathable bag into the waste box 3 and close the door.

[0046] To achieve the basic functions of the cutting equipment, the cutting equipment in this embodiment may also include other necessary modules or components, such as material conveying mechanisms and control systems. It should be noted that any suitable existing structure can be selected from the other necessary modules or components included in the cutting equipment. To clearly and concisely illustrate the technical solution provided in this embodiment, the above-mentioned parts will not be repeated here, and the accompanying drawings have also been simplified accordingly. However, it should be understood that the scope of this utility model is not limited as a result.

[0047] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
