Description

Technical Field

[0002] With the development of science and technology and the progress of society, the intelligent manufacturing industry has continuously made new breakthroughs and developed a series of advanced equipment and non-standard equipment that can improve production, manufacturing and operation efficiency. The efficient and automated processing of non-standard equipment is crucial to improving production efficiency and reducing costs. Especially in the automatic separation process of fastening parts, the flexible separation card mechanism is a non-standard equipment used in the intelligent manufacturing industry, which is used to automatically separate the fastening parts. However, in the actual production process, the need for automatic separation of fastening parts is growing, and the related processing methods and equipment still have considerable limitations and challenges. A common way to automatically separate fastening parts is to design a set of clamping mechanisms, first clamp the workpiece in a certain direction, and then separate the workpiece horizontally through another set of clamping mechanisms with a pulling function. However, this method often causes the entire set of mechanism structures to be too complicated in actual applications. Not only does it occupy a large area and require a high space, but its cost is also relatively high, which is not suitable for large-scale use under cost constraints.

[0003] In addition, the automatic separation and fastening mechanism of the card is relatively difficult to maintain and repair due to its complex design structure, which requires considerable manpower and material resources. Once a failure occurs, it may cause the entire production line to stop, resulting in large economic losses. Moreover, due to its many components and complex structure, the risk of failure is also increased. Therefore, high maintenance costs and high failure rates are also a major problem of this method.

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0018] Reference Figure 1 to Figure 2As shown, the utility model discloses a flexible separation card mechanism, specifically, the mechanism includes a base assembly, a flexible assembly and a clamping assembly; the flexible separation card mechanism includes a base assembly, a flexible assembly and a clamping assembly. The base assembly is slidably connected to the flexible assembly, and the end of the flexible assembly is fixedly connected to the clamping assembly. A driving mechanism is arranged on the base assembly to provide power for the flexible assembly. The flexible assembly is the core of the mechanism, which includes a slide rail connection block 201, a pull rod 202, a first balance bar 203, a second balance bar 205, a center connecting rod 204, a clamping claw fixing rod 207, a clamping claw 302 and an angle connecting rod 206. The slide rail connection block 201 slides along the base assembly and is connected to the output end of the driving mechanism, thereby driving the entire flexible assembly. One end of the pull rod 202 and the first balance bar 203 are respectively hinged to the two ends of the slide rail connection block 201, so that a four-bar linkage is basically formed. Then the other ends of the pull rod 202 and the first balance rod 203 are hinged to the central link 204, so that the four-bar linkage can perform independent arc motion at both ends. One end of the angle link 206 is hinged to the base plate 101 assembly, and the center position of the angle link 206 is hinged to the central link 204. One end of the second balance rod 205 is hinged to one end of the angle link 206, and the other end is hinged to one end of the clamping claw fixed rod 207. The center position of the clamping claw fixed rod 207 is hinged to one end of the central link 204 away from the pull rod 202, and the other end of the clamping claw fixed rod 207 is fixedly connected to the clamping assembly. The clamping assembly here is used to perform actual workpiece clamping operations. The mechanism is simple and efficient, and can achieve accurate card separation with less space occupation and cost, greatly improving production efficiency.

[0019] Furthermore, the base assembly, as the basic part of the entire flexible separation card mechanism, plays a key supporting and driving role. The base assembly includes a base plate 101, a slide rail 102 and a cylinder 103; the base plate 101 serves as the base of the entire mechanism, providing a stable installation platform for the slide rail 102 and the cylinder 103, thereby ensuring the stability and reliability of the equipment. The slide rail 102 is fixedly mounted on the base plate 101, and the slide rail 102 is slidably connected to the sliding connection block. The cylinder 103 is arranged at the top of the base plate 101, and the output shaft of the cylinder 103 is fixedly connected to the sliding connection block. The main function of the slide rail 102 is to provide linear motion guidance for the sliding connection block, limit the degree of freedom, and ensure that it can only move along a preset linear path. The cylinder 103 is the driving part of the entire mechanism. By controlling the extension and contraction of the cylinder 103, the sliding connection block can be pushed or pulled to perform linear motion back and forth along the slide rail 102. The movement of the cylinder 103 can be precisely controlled, so that the precise control of the movement position and speed of the sliding connection block can be achieved.

[0020] Furthermore, the clamping assembly includes a bidirectional cylinder 301 and a clamping jaw 302, which is the part of the flexible separation card mechanism for actual operation. The bidirectional cylinder 301 is fixedly mounted on the clamping jaw 302 fixed connecting rod, and the two output ends of the bidirectional cylinder 301 are arranged on the same side and move in opposite directions, and its two output ends are fixedly connected with the clamping jaw 302. The bidirectional cylinder 301 serves as a driving part, and it can perform telescopic movement in two directions under the action of input air pressure, which enables the bidirectional cylinder 301 to control the clamping jaw 302 to perform opening and closing movement. The clamping jaw 302 serves as the execution part of the mechanism and performs actual workpiece clamping operation. By controlling the bidirectional cylinder 301, the precise opening and closing of the clamping jaw 302 can be achieved, thereby realizing the pick-up and placement operation of the workpiece. In actual operation, the bidirectional cylinder 301 realizes its telescopic movement by controlling the internal air pressure. If the two output ends of the two-way cylinder 301 are extended outward, the clamping jaws 302 will open; conversely, when the two output ends of the two-way cylinder 301 are contracted, the clamping jaws 302 will close, thereby completing the clamping of the workpiece. The angle connecting rod 206 and the center connecting rod 204 hinge point to the angle connecting rod 206 and the bottom plate 101 hinge point are arranged in an S shape. The S-shaped arrangement of the angle connecting rod 206 provides a greater curvature, so that the mechanism can maintain good adaptability and flexibility under different operating conditions, and it can convert the above-mentioned upward linear motion into rotational motion. In this process, the bottom plate 101 and the clamping jaw fixing rod 207 produce an angle change, thereby changing the position and opening and closing state of the clamping jaws 302.

[0021] The first balance bar 203 is consistent in length with the pull rod 202, the second balance bar is arranged in parallel with the central link 204, and the length of the second balance bar 205 is consistent with the distance from the hinge point of the central link 204 and the angle link 206 to the hinge point of the central link 204 and the clamp fixing rod 207. Since the first balance bar 203 and the pull rod 202 are consistent in length, they can maintain complete synchronization during movement. This means that during the movement of the mechanism, the two will move at the same angle and speed, thereby ensuring the balance and symmetry of the mechanical movement. Such synchronous movement can reduce the mechanical stress and wear caused by the asynchronous components and extend the service life of the equipment. The parallel arrangement of the second balance bar 205 and the central link 204 helps to maintain the stability of the entire mechanism. The parallel arrangement can balance the force and prevent tilting or distortion caused by uneven force. The length of the second balancing rod 205 is consistent with the distance between the hinge points of the central link 204 and the angle link 206, which helps to maintain the balance of torque. The balance of torque ensures smooth mechanical movement and reduces the extra burden caused by unbalanced torque.

[0022] The beneficial effect of the utility model is that the power is transmitted to the angle connecting rod through the pull rod and the center connecting rod, and then the bottom plate and the clamp fixing rod are quickly turned to form a reasonable angle under the action of the balance rod. Thus, a large separation force is generated under a small input power, the separation task of the fastening card is effectively completed, and the operation efficiency and accuracy are improved. The structure is relatively simple, the investment cost is low, and the applicability is strong.

[0023] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
