Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a fixture structure for a wire insertion and removal mechanism. Background Art

[0002] In electronic devices, a good connection between the plug and the interface is crucial for ensuring accurate and stable data transmission. If the connection is unreliable, it may lead to data loss, transmission interruption or errors, affecting the normal function of the device. At the same time, frequent plugging and unplugging operations without testing may cause physical damage to the plug and interface. Problems such as bent pins and loose interfaces may gradually appear during long-term use. Early testing can detect these problems in time, avoid further damage, and extend the service life of the device.

[0003] Chinese patent CN221630725U, published on August 30, 2024, discloses a wire-pulling mechanism based on visual positioning technology. The mechanism uses a material-grabbing component to grasp the product and position the jig head of the product on one side of a stop on the top of the placement base. The stop then intercepts and limits the jig head, while the material-grabbing component continues to grasp and move the product, thereby separating the jig head from the product and achieving the purpose of wire pulling. A first magnet is fixedly installed on the top of the base, and a second magnet is installed on the jig head. The second magnet and the first magnet can be magnetically attracted to each other, thereby firmly adsorbing the jig head that has detached from the product onto the top of the placement base.

[0004] Although the aforementioned patent can fix the jig head to the placement base by the attraction between magnets, the jig head may not be able to abut against the stop block when it is magnetically fixed due to the influence of processing accuracy. This will cause the positional accuracy of the jig head to be uncontrollable, affecting the success rate of the wire insertion claw. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fixture structure for a plug-in / plug-out mechanism. By utilizing the relative position between the first magnet and the second magnet, a magnetic attraction force is generated to drive the plug to firmly abut against the side of the shoulder, thereby ensuring the positional accuracy of the plug on the fixture block and facilitating the clamping of the plug-in clamp.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A fixture structure for a plug-in / plug-out mechanism includes a fixture block and a plug. A first magnet is provided at the bottom of the plug, and a shoulder is provided at the top of the fixture block to prevent the plug from moving horizontally. A second magnet is provided on one side of the shoulder, which can magnetically attract the first magnet but is not coaxial. The second magnet can drive the plug to abut against the inner side of the shoulder through the first magnet.

[0008] Optionally, the length direction of the shoulder rest is parallel to the Y-axis, the outer diameters of the first magnet and the second magnet are the same, and when the end of the plug abuts against the inner side of the shoulder rest, the second magnet is offset forward relative to the first magnet along the X-axis direction.

[0009] Optionally, the distance between the axes of the first magnet and the second magnet along the X-axis is 1.5 mm.

[0010] Optionally, two visual positioning holes are provided on the plug near the end edge, and the two visual positioning holes are symmetrically distributed on both sides of the first magnet.

[0011] Optionally, both the first magnet and the second magnet have a ring-shaped structure, and the second magnet is fixedly mounted on the fixture block by fasteners.

[0012] Optionally, the top of the jig block has a groove for mounting the second magnet, the bottom of the groove has a threaded hole, and one end of the fastener passes through the second magnet and is screwed into the threaded hole.

[0013] Optionally, the bottom of the fixture block is provided with mounting holes for assembly.

[0014] Optionally, the fixture block includes a block body, a boss is provided on one side of the block body, a notch is provided on the upper part of the boss, and the shoulder is provided on the top of the block body.

[0015] Optionally, the shoulder is located at the top edge of the block, and the shoulder, the block, and the boss are integrally formed.

[0016] Optionally, the second magnet does not protrude from the top of the fixture block, and the first magnet does not protrude from the bottom of the plug.

[0017] Beneficial effects

[0018] In this invention, the plug can move horizontally until it comes into contact with the shoulder. The plug separates from the interface and remains on the fixture block. By utilizing the positional deviation of the first magnet and the second magnet, the second magnet can generate a magnetic attraction force on the first magnet, thereby driving the plug to firmly abut against the inner side of the shoulder. This ensures that the plug is firmly fixed on the fixture block and also ensures the positional accuracy of the plug on the fixture block, making it easy for the wire clamp to pick up the plug.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figures 1-4 As shown, a fixture structure for a plug-in / plug-out mechanism includes a fixture block 1 and a plug 3. A first magnet 4 is provided at the bottom of the plug 3. A shoulder 2 for blocking the horizontal movement of the plug 3 is provided at the top of the fixture block 1. A second magnet 5 that can magnetically attract the first magnet 4 is provided on one side of the shoulder 2. The first magnet 4 and the second magnet 5 are not coaxial and have a certain positional deviation between them. The plug 3 is plugged into the product through an interface.

[0030] Based on visual positioning technology, during wire unplugging: a robot moves the product horizontally, and the protruding shoulder 2 on fixture block 1 blocks the plug 3. The robot continues to move forward with the product, allowing the plug 3 to be easily pulled out and remain on fixture block 1. During wire insertion: after fixture block 1 carrying the plug 3 is transported from the wire unplugging station to the wire insertion station, a six-axis robot uses insertion grippers to pick up the plug 3 and then inserts it into the corresponding product's interface. This repeated unplugging and insertion test allows for timely detection of problems, facilitating later resolution and extending the product's lifespan.

[0031] Specifically, the plug 3 can move horizontally until it comes into contact with the shoulder 2. The plug 3 separates from the interface and remains on the fixture block 1. By utilizing the positional deviation of the first magnet 4 and the second magnet 5, the second magnet 5 can generate a magnetic attraction force on the first magnet 4, thereby driving the plug 3 to firmly abut against the inner side of the shoulder 2. That is, the second magnet 5 can drive the plug 3 to abut against the inner side of the shoulder 2 through the first magnet 4. This ensures that the plug 3 is firmly fixed on the fixture block 1 and also ensures the positional accuracy of the plug 3 on the fixture block 1, which is convenient for the wire clamp to pick up.

[0032] As described above, two visual positioning holes 301 are provided on the plug 3 near the end edge. The two visual positioning holes 301 are distributed along the Y-axis direction and are symmetrically distributed on both sides of the first magnet 4.

[0033] The visual positioning technology can determine the specific position of the plug 3 in the Y-axis direction through two visual positioning holes 301. The plug 3 abuts against the inner side of the shoulder 2, which can ensure the specific position of the plug 3 in the X-axis direction. Since the height of the fixture block 1 is fixed, the plug 3 is placed on the fixture block 1, which can determine the specific position of the plug 3 in the Z-axis direction. Therefore, through this structure, the plug 3 can be easily gripped by the wire clamp, which can improve the success rate of gripping.

[0034] During the movement of plug 3, friction will inevitably occur between it and fixture block 1. In order to ensure that plug 3 is in a horizontal position on fixture block 1, the second magnet 5 does not protrude from the top of fixture block 1 and the first magnet 4 does not protrude from the bottom of plug 3, so as to avoid the magnets affecting the position of plug 3.

[0035] The first magnet 4 and the second magnet 5 both adopt a ring-shaped structure, and the second magnet 5 is fixedly installed on the jig block 1 by fasteners; the top of the jig block 1 is provided with a groove 61 for installing the second magnet 5, the bottom of the groove 61 is provided with a threaded hole 62, and one end of the fastener passes through the second magnet 5 and is screwed into the threaded hole 62.

[0036] The circular structure not only facilitates installation but also helps to distinguish the direction of magnetic force. The fastener is a screw, which passes through the center of the second magnet 5 and is screwed into the threaded hole 62 to firmly fix the second magnet 5 on the jig block 1, and the second magnet 5 is completely embedded in the groove 61.

[0037] The bottom of the jig block 1 is provided with mounting holes 14 for assembly. Fasteners such as screws are inserted from bottom to top, which makes it easy to assemble the jig block 1 onto the existing conveyor line.

[0038] like Figure 3As shown, the jig block 1 includes a block body 11, a boss 12 is provided on one side of the block body 11, a notch 13 is provided on the upper part of the boss 12, and a shoulder 2 is provided on the top of the block body 11; the shoulder 2 is located at the edge of the top of the block body 11, and the shoulder 2, the block body 11 and the boss 12 adopt an integral molding structure.

[0039] The jig block 1 adopts a one-piece molded structure. The outer side of the shoulder 2 is flush with the side of the block 11. This is to facilitate the production and manufacturing of the jig block 1. It can be achieved by simply machining such as milling and drilling. Moreover, the one-piece molded structure has higher relative positional accuracy between the components. The boss 12 is narrower than the block 11. This structure makes it easier for workers to pick up the jig block 1. The notch 13 is opened on the upper part of the boss 12 to facilitate the manual removal of the plug 3 from the jig block 1.

[0040] Here, the side of the shoulder rest 2 closest to the second magnet 5 is considered the inner side, and the opposite side is considered the outer side, while the end of the second magnet 5 closest to the shoulder rest 2 along the X-axis is considered the front end.

[0041] like Figures 1-2 , Figures 5-6 As shown, the length direction of the shoulder rest 2 is parallel to the Y-axis. The outer diameters of the first magnet 4 and the second magnet 5 are the same. When the end of the plug 3 abuts against the inner side of the shoulder rest 2, the second magnet 5 is offset forward relative to the first magnet 4 along the X-axis direction. That is, the axis of the second magnet 5 is closer to the shoulder rest 2 than the first magnet 4 along the X-axis direction.

[0042] Having the same outer diameter makes it easy to calculate and test the direction and magnitude of the magnetic attraction force; through this structure, it is possible to prevent the end of the plug 3 from not abutting against the inner side of the shoulder 2 after it is detached from the interface, thus ensuring the positional accuracy of the plug 3 relative to the fixture block 1 in the X-axis direction.

[0043] The first magnet 4 and the second magnet 5 attract each other. If a magnetic force is needed to make the plug 3 move forward, the second magnet 5 can only be placed in the forward position. Conversely, if the first magnet 4 and the second magnet 5 are both in the middle and their axes coincide, only a magnetic force in the Z-axis direction can be generated, but no magnetic force in the X-axis direction can be generated. If the first magnet 4 is placed in the forward position, the second magnet 5 will generate a backward magnetic force on the first magnet 4, which is contrary to the original intention of this solution.

[0044] To achieve the goal of placing the first magnet 4 in a forward position while the second magnet 5 exerts a forward magnetic force on the first magnet 4, the first magnet 4 and the second magnet 5 must be in a repulsive relationship. However, in this case, it cannot be guaranteed that the plug 3 is firmly fixed on the fixture block 1.

[0045] Based on the aforementioned structural relationship, if the outer diameter of the first magnet 4 and the second magnet 5 is 10mm, according to actual testing, the optimal distance b between the axes of the first magnet 4 and the second magnet 5 along the X-axis is 1.5mm; that is, the distance d between the axis of the first magnet 4 and the front end of the plug 3 along the X-axis is 16mm, and the distance f between the axis of the second magnet 5 and the inner side of the shoulder 2 along the X-axis is 14.5mm.

[0046] In summary, the fixture structure for the plug-in / plug-out mechanism proposed in this utility model offsets the magnet on the plug 3 from the magnet on the fixture block 1 by a certain distance, generating a magnetic attraction force that allows the plug 3 to press against the shoulder 2 of the fixture block 1. This not only solves the problem that the plug 3 is not fixed during transportation and is prone to falling off the fixture block 1, but also improves the success rate of the plug clamps in gripping the plug 3.
