[0036] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0037] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0038] In related technologies, cutting mechanisms are generally used to cut workpieces. When the cutting mechanism is working, the cutter and the workpiece move relative to each other. When the cutter comes into contact with the workpiece, the cutting operation is performed. Since debris is generated during the cutting process, and the debris is prone to fly out of control, the flying debris can easily damage the workpiece when it comes into contact with it. The debris remaining on the cutter surface can also damage the cutter surface, ultimately leading to a decrease in the yield rate in the cutting process stage.
[0039] When a cutting mechanism needs to clean up debris, it usually uses air blowing or suction to blow or suck the debris away from the surface of the workpiece.
[0040] However, neither of these methods can guarantee where the debris will land after it splashes. During the cutting process, debris will still splash onto the surface of the workpiece and the cutting blade, ultimately leading to product quality issues.
[0041] In view of this, embodiments of this application provide an anti-escape cutting mechanism, a tab processing device, and a battery production device. The anti-escape cutting mechanism includes a cutting blade assembly for cutting a workpiece; a cutting position, which is the position where the cutting blade assembly cuts the workpiece; a blocking mechanism having at least one open semi-enclosed space, the semi-enclosed space being used to surround the cutting position; and a driving mechanism, the cutting blade assembly and / or the blocking mechanism being disposed within the driving mechanism, the driving mechanism being used to realize relative movement between the cutting blade and the cutting position.
[0042] The cutting mechanism provided in this application embodiment, by setting a blocking mechanism to surround the cutting position, confines the debris generated during the cutting process within a certain space, prevents the debris from flying to the surface of the workpiece, and improves the yield of products in the cutting process stage.
[0043] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.
[0044] Firstly, referring to Figure 1 The present application provides an anti-escape cutting mechanism, including a cutting assembly for cutting the workpiece.
[0045] The cutting position is the position where the cutting blade assembly cuts the workpiece.
[0046] The blocking mechanism has at least one semi-enclosed space with an opening, and the semi-enclosed space is used to surround the cutting position, separating the cutting part and the non-cutting part of the workpiece. The cutting part is surrounded within the blocking mechanism, and the non-cutting position is located outside the blocking mechanism. When flying debris is generated during the cutting process, the blocking mechanism can block the debris outside the non-cutting part, preventing the debris from flying to the non-cutting part and causing damage to the non-cutting part.
[0047] A drive mechanism, a cutter assembly, and / or a blocking mechanism are provided in the drive mechanism, which is used to realize the relative movement between the cutter and the cutting position.
[0048] The above design ensures the integrity of the cutting mechanism and provides a semi-enclosed space to effectively prevent waste from splashing onto the surface of the workpiece.
[0049] As one feasible implementation, the blocking mechanism also includes an upper blocking member and a lower blocking member, which can move relative to each other. When the cutting work is performed, the upper blocking member and the lower blocking member combine to form a semi-enclosed space with at least one opening that surrounds the cutting position.
[0050] In one feasible implementation, the cutting assembly includes an upper cutting blade and a lower cutting blade. The upper cutting blade is mounted on an upper blocking member, and the lower cutting blade is mounted on a lower blocking member. When the cutting mechanism performs cutting work, the upper cutting blade and the lower cutting blade move relative to each other to shear the workpiece located between the upper cutting blade and the lower cutting blade.
[0051] As one feasible implementation, the upper blocking member is provided with a chip discharge groove, which is connected to the clearance groove to provide a waste discharge channel for the cutting debris.
[0052] For example, the upper blocking member is provided with an air blowing hole that penetrates the upper blocking member. The hole connects the semi-enclosed space enclosed by the blocking mechanism and the positive pressure air blowing device. When the cutting work is performed, the air blowing hole is filled with positive pressure gas, which acts on the cutting position to prevent cutting debris from sticking to the tool and causing tool damage, thus affecting the tool life.
[0053] For example, the anti-escape cutting mechanism also includes a waste channel connected to a blocking mechanism for discharging waste and debris generated during the cutting of the workpiece.
[0054] As one feasible implementation, the escape-proof cutting mechanism also includes a dust removal air pipe that connects the waste channel and the negative pressure suction device to provide negative pressure gas to the waste channel to assist in the discharge of debris and waste from the waste channel.
[0055] For example, the anti-escape cutting mechanism also includes an upper substrate and a lower substrate, with the upper substrate connected to an upper blocking member and the lower substrate connected to a lower blocking member.
[0056] As one feasible implementation, the drive mechanism also includes an electric cylinder with a piston rod. The electric cylinder is connected to the upper base plate, and the end of the piston rod is connected to the lower base plate. The electric cylinder can drive the upper and lower blocking members to move in opposite directions, and the upper and lower cutters move in opposite directions accordingly. The workpiece is placed between the upper and lower cutters. When the upper and lower blocking members abut against each other, a semi-enclosed space is formed. The workpiece and the cutter assembly are located within the semi-enclosed space. At this time, the cutter assembly cuts the workpiece within the semi-enclosed space. The waste and debris generated within the semi-enclosed space will not splash onto the non-cutting position of the workpiece.
[0057] For example, the lower substrate is equipped with guide posts, and the upper substrate is provided with through holes for the guide posts to pass through. When the electric cylinder drives the upper substrate and the lower substrate to move towards each other, the guide posts can assist the upper substrate and the lower substrate to move in a straight line towards each other.
[0058] As one feasible implementation, the surface of the upper cutter is coated. Since the debris generated during the cutting process is easy to stick to the upper cutter, long-term accumulation will affect the upper cutter's cutting work or cause damage to the upper cutter. Therefore, the coating on the surface of the upper cutter reduces the probability of the above problems occurring.
[0059] For example, the coating on the surface of the upper cutter is a colored diamond DLC coating.
[0060] Secondly, embodiments of this application provide a tab processing device, including the aforementioned anti-escape cutting mechanism.
[0061] For example, the electrode processing equipment may be electrode cutting equipment, electrode sheet cutting equipment, etc. This application does not limit the specific type of electrode processing equipment.
[0062] Thirdly, embodiments of this application provide a battery production apparatus, including tab processing equipment.
[0063] It is understood that since the battery production equipment of this application adopts the technical solution of the above-described anti-escape cutting mechanism embodiment, it has at least the beneficial effects brought about by the technical solution of the above-described embodiment, which will not be elaborated here.
