Abstract

This utility model relates to the field of product processing and manufacturing technology, specifically to a horizontal blade cutting mechanism suitable for thin film cutting in MLCC stacking machines. It includes an electric cylinder, a connecting mechanism, a cutting device, and a positioning device. The end of the driving piston rod of the electric cylinder is connected to the top of the connecting mechanism, and the bottom of the connecting mechanism is connected to the cutting device. The positioning device is positioned close to the electric cylinder. In actual use, after receiving an action signal, the electric cylinder pushes the piston rod to a preset position, causing the connecting mechanism to drive the cutting device to move vertically along the positioning device.

Description

Technical Field

[0001] This utility model relates to the field of product processing and manufacturing technology, and in particular to a cross-blade cutting mechanism suitable for thin film cutting in MLCC stacking machines. Background Technology

[0002] Currently, MLCC stacking machines typically use a rotary blade cutting mechanism for material (film) cutting. This type of structure generally uses cylinders to control the cutting depth on all four sides, springs to buffer the transition depth, and a motor to provide translational force for the blades. Since the blades themselves have no power for rotation, their rotation relies primarily on the rolling friction between the blade and the film as the blade presses down. This design has two main drawbacks: first, the cutting depth cannot be precisely controlled or quickly adjusted, and each of the four blades cannot be individually controlled; second, the blades rely on rolling friction for rotation, so when the rolling friction is insufficient or the blade is out of round, the cutting will change from rotary cutting to sliding cutting, meaning the film is not cut by the blade but rather slashed. This results in poor cut quality in the film cutting process, including but not limited to cuts that are too deep or too shallow, poor cut straightness, rough cuts, and damage to the film in non-cutting areas. Those familiar with the equipment processes in this industry know that the next step after cutting is film peeling. Therefore, the quality of the cut directly affects the quality of the subsequent peeling, and the quality of the peeling ultimately affects the quality of the laminated product.

[0003] This utility model innovates the cutting blade design and cutting structure to solve the cutting pain points caused by the use of circular blade cutting mechanisms in the current MLCC stacking machine, thereby avoiding the problem of poor cuts that ultimately affect the quality of stacked products, avoiding cuts that are too deep or too shallow, and avoiding poor cut straightness, rough cuts, and damage to the film in non-cut areas. Utility Model Content

[0004] The purpose of this utility model is to provide a cross-blade cutting mechanism suitable for film cutting in MLCC stacking machines. By innovating the cutting blade design and cutting structure, it can avoid the problem of poor cuts that ultimately affect the quality of stacked products, avoid cuts that are too deep or too shallow, and avoid poor cut straightness, rough cuts, and damage to the film in non-cutting areas.

[0005] To achieve the above objectives, this utility model provides a cross-blade cutting mechanism for thin film cutting in MLCC stacking machines, including an electric cylinder, a connecting mechanism, a cutting device, and a positioning device. The end of the drive piston rod of the electric cylinder is connected to the top end of the connecting mechanism, the bottom end of the connecting mechanism is connected to the cutting device, and the positioning device is located close to the electric cylinder.

[0006] The cutting device includes a blade holder and a straight cutting blade. The blade holder is connected to the end of the drive piston rod of the electric cylinder via a connecting mechanism. The straight cutting blade is mounted on the blade holder at three points.

[0007] The positioning device includes positioning guide posts and a mechanical reset detection sensor. The positioning guide posts are symmetrically installed on both sides of the tool holder. The mechanical reset detection sensor is disposed between the positioning guide posts and the electric cylinder.

[0008] The connecting mechanism includes a clamp-type structure, a multi-piece segmented fixing ring structure, and a threaded fixing seat structure, which are arranged sequentially from top to bottom. The threaded fixing seat structure is connected to the tool holder.

[0009] The cutting straight blade includes a blade body and a blade edge, with the blade body and the blade edge being fitted together.

[0010] This utility model discloses a horizontal blade cutting mechanism for thin film cutting in MLCC stacking machines, including an electric cylinder, a connecting mechanism, a cutting device, and a positioning device. In actual use, after receiving an action signal, the electric cylinder pushes the piston rod to a preset position, causing the connecting mechanism to drive the cutting device to move vertically along the positioning device. The cutting action is completed sequentially by detecting the positioning. The connecting mechanism is a specially designed floating connection structure, which enables independent and precise control of the cutting depth (down to the micrometer level) and cutting speed of each side of the cutting device, greatly improving the convenience of operation or maintenance personnel, avoiding excessively deep or shallow cuts, and preventing poor cut straightness, rough cuts, and damage to the film in non-cutting areas.

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The first embodiment of this application is:

[0018] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of the cross-blade cutting mechanism for thin film cutting in MLCC stacking machines. Figure 2 This is a structural diagram of the connecting mechanism. Figure 3 This is a side view of the straight cutting blade. This utility model provides a horizontal blade cutting mechanism suitable for thin film cutting in MLCC (Multi-Layer Ceramic Capacitor) stacking machines: it includes an electric cylinder 1, a connecting mechanism 2, a cutting device, and a positioning device. The cutting device includes a blade holder 3 and a straight cutting blade 4. The positioning device includes a positioning guide post 5 and a mechanical reset detection sensor 6. The connecting mechanism 2 includes a clamp-type structure 201, a multi-piece point-fixed ring structure 202, and a threaded fixing seat structure 203. The straight cutting blade 4 includes a blade body 401 and a cutting edge 402. The aforementioned solution addresses the cutting challenges inherent in the circular blade cutting mechanism used in current MLCC stacking machines, which negatively impact the quality of stacked products. These challenges include poor cut depth, shallow cuts, poor cut straightness, rough cuts, and damage to the film in non-cut areas. It is understood that this solution can be used to innovate the blade design and cutting structure, thereby avoiding these issues that ultimately affect the quality of stacked products, preventing cuts that are too deep or too shallow, and avoiding problems such as poor cut straightness, rough cuts, and damage to the film in non-cut areas.

[0019] In this specific embodiment, the drive piston rod end of the electric cylinder 1 is connected to the top end of the connecting mechanism 2, and the bottom end of the connecting mechanism 2 is connected to the cutting device. The positioning device is located close to the electric cylinder 1. The drive source for each side (four sides in total) of this cutting mechanism is provided by the electric cylinder 1. The drive piston rod end of the electric cylinder 1 is connected to the cutting device through the connecting mechanism 2. When the electric cylinder 1 is started, it drives the connecting mechanism 2 to drive the cutting device to perform its function, thereby cutting the material through the cutting device. The positioning device can improve the stability of the movement of the cutting device and fix the drive movement trajectory. Furthermore, the electric cylinder 1 has... It has a position feedback function, which can prevent malfunctions to a certain extent and design interlocking linkage. In actual use, after the electric cylinder 1 receives the action signal, it pushes the piston rod to the preset position, causing the connecting mechanism 2 to drive the cutting device to move vertically along the positioning device. The cutting action is completed sequentially by detecting the positioning. The connecting mechanism 2 is a specially designed floating connection structure, which enables independent and precise control of the cutting depth (down to the micrometer level) and cutting speed of the cutting device on each side. This greatly improves the convenience of operation or maintenance personnel and avoids cutting too deep or too shallow, as well as poor cutting straightness, rough cutting, and damage to the film in non-cutting areas.

[0020] The cutter holder 3 is connected to the drive piston rod end of the electric cylinder 1 via the connecting mechanism 2. The cutting straight blade 4 is mounted on the cutter holder 3 using a three-point design. The cutter holder 3 is located at the bottom of the connecting mechanism 2. The three-point design allows the cutting straight blade 4 to be mounted on the cutter holder 3, which improves the movement stability and fixed drive trajectory of the cutting straight blade 4 during the material cutting process. This enables independent and precise control of the cutting depth (down to the micrometer level) and cutting speed of each side of the cutting straight blade 4. Even if the cutting distance (distance from the blade 402 to the cutting target) of the four sides of the cutting straight blade 4 is different, it does not affect the overall cutting uniformity. This eliminates the impact of various differences on the cutting of the equipment and enhances the independent controllability of each side. Furthermore, it can be directly operated and adjusted on the modified host program human-machine interface (provided that the host manufacturer grants permission), greatly improving the convenience of operation or maintenance personnel.

[0021] Secondly, the positioning guide posts 5 are symmetrically installed on both sides of the blade holder 3; a mechanical reset detection sensor 6 is provided between the positioning guide post 5 and the electric cylinder 1. The positioning guide post 5 is installed on the conveying head of the stacking equipment with the bushing of the electric cylinder 1 and the positioning guide post 5 as a reference, and the cutting straight blade 4 is attached to the side of the suction plate. After the electric cylinder 1 receives the action signal, it drives the connecting structure to move the blade holder 3 and the cutting straight blade 4 downward on the positioning trajectory of the positioning guide post 5. After the cutting is completed, the driving electric cylinder 1 receives the return signal from the structure, and the piston rod pulls the connecting mechanism 2, which moves the blade holder 3 and the cutting straight blade 4 upward on the positioning trajectory of the positioning guide post 5. A complete cutting action is completed when the mechanical reset detection sensor 6 detects that the mechanical terminal has been reset. All action points need to be coordinated with the action sequence of the main body of the stacking equipment. The mechanical reset detection sensor 6 detects whether the mechanical terminal has been reset, which is conducive to the safe execution of subsequent actions, improves the cutting quality, and greatly improves the convenience of operation or maintenance personnel.

[0022] Meanwhile, the clamp-type structure 201, the multi-piece segmented fixing ring structure 202, and the threaded fixing seat structure 203 are arranged sequentially from top to bottom. The threaded fixing seat structure 203 is connected to the tool holder 3. The clamp-type structure 201 can engage with the piston rod of the electric cylinder 1. The multi-piece segmented fixing ring structure 202 is in the middle, and the threaded fixing seat structure 203 is on the other side. The threaded fixing seat structure 203 can be connected to the tool holder 3. The advantages of this structure are that it can connect two different fixing methods, and the floating characteristics can eliminate stress during mechanical movement while maintaining connection accuracy, thereby improving cutting stability and cutting quality.

[0023] Furthermore, the blade body 401 is fitted with the blade edge 402, and the cutting straight blade 4 is formed by the fitting of the blade body 401 and the blade edge 402. The blade body 401 can be made of ordinary stainless steel, a metal with relatively low cost and general properties, while the blade edge 402 is made of tungsten steel, which has relatively high hardness. This type of cutting straight blade 4 is more durable, has lower replacement costs, and offers significant advantages such as good cutting straightness and high stamping stability, which are beneficial to the cut. The traditional cutting blade has been changed from the original optional round blade to the stamped cutting straight blade 4 (straight blade type). The wider blade design can enhance the rigidity of the blade body, making it less prone to deformation, and improving the straightness of the cut and its lifespan. The nested design between the blade edge 402 and the blade body 401 means that only the blade edge 402 needs to be replaced when damaged, further reducing the replacement cost of the cutting blade. Moreover, the stamped straight blade type cutting results in a smooth cut without affecting the film in non-cutting areas, thus improving the cutting quality.

[0024] When using the horizontal blade cutting mechanism for film cutting in MLCC stacking machines according to this embodiment, in actual use, after the electric cylinder 1 receives the action signal, it pushes the piston rod to the preset position, causing the connecting mechanism 2 to drive the cutting device to move vertically along the positioning device. The cutting action is completed sequentially by detecting the positioning. The connecting mechanism 2 is a specially designed floating connection structure, which enables independent and precise control of the cutting depth (down to the micrometer level) and cutting speed of the cutting device on each side, greatly improving the convenience of operation or maintenance personnel, avoiding excessively deep or shallow cuts, and avoiding poor cut straightness, rough cuts, and damage to the film in non-cutting areas.

[0025] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
