Description

Technical Field

[0001] The utility model relates to the technical field of linear modules, in particular to a linear module with a buffer component. Background Art

[0002] Due to the characteristics of fast single-unit movement speed, high repeat positioning accuracy, light body weight, small equipment space and long life, linear modules are widely used in loading and unloading robots, cutting equipment, gluing equipment, mounting equipment and other equipment. They have made indispensable contributions to the development of domestic equipment manufacturing, reduced dependence on imported complete sets of equipment, and brought more opportunities for equipment research and development and manufacturing.

[0003] Existing linear modules mainly rely on electrical components to control movement and stop. Once the electrical components fail or there is a problem with the circuit, the slider may directly hit other parts, resulting in accuracy errors or equipment damage, and even causing safety hazards.

[0004] In the patent document with the announcement number CN206770500U, a linear module with a buffer is disclosed. The buffer is set on the slider and the bearing fixing seat. The buffer mainly includes a buffer block or a buffer pad or a shock-absorbing block or a shock-absorbing pad, which plays the role of buffering and mechanical jamming, increases the protection of the module, and effectively reduces the impact of the slider on the bearing fixing seat and the screw fixing seat when the sensor fails, avoids the accuracy being affected or the module being damaged, increases the service life of the module, and reduces the cost of use.

[0005] However, the linear module with a buffer member uses the buffer member to prevent the slider from colliding with the screw fixing seat and the bearing fixing seat during use. When the impact force is large, the module components will still be damaged. Therefore, it is necessary to propose a linear module with a buffer member. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1-4 , the utility model provides a technical solution: Example

[0025] A linear module with a buffer component includes a housing 1, a slide rail 3 arranged inside the housing 1, and a slider 2 arranged on the top of the slide rail 3. A buffer mechanism is provided on one side of the slide rail 3.

[0026] The buffer mechanism includes a back plate 301, a rubber block 302, a fixed plate 303, an insulating plate 304, a limit rod 305, a spring 306, a limit block 307 and a magnetic plate 308. The fixed plate 303 is fixedly connected to one side of the slide rail 3, and the back plate 301 and the insulating plate 304 are movably connected to the top of the slide rail 3. Four through holes are opened on one side of the back plate 301 and the fixed plate 303 to cooperate with the limit rod 305, and four springs 306 are evenly distributed on one side of the insulating plate 304. The rubber block 302 is disposed between the back plate 301 and the fixed plate 303. The limit rod 305 is fixedly connected to one side of the insulating plate 304. The spring 306 is movably connected to the outside of the limit rod 305. The limit block 307 is fixedly connected to the outer surface of the limit rod 305. The magnetic plate 308 is fixedly connected to the left side of the back plate 301. A magnetic plate that repels the magnetic plate 308 is disposed on the left side of the insulating plate 304. A through hole is formed through one side of the insulating plate 304. The through hole has a diameter large enough to prevent interference with the screw rod 4. The two repelling magnetic plates 308 will always generate a mutually repelling force. The buffer mechanism can be disposed on the left and right ends of the slide rail 3. The left buffer mechanism is not shown in the figure. When the slider 2 is about to collide, first, the slider 2 contacts the insulating plate 304. At this time, the magnetic plate set on one side of the insulating plate 304, which repels the magnetic plate 308, will generate a mutual repulsive force when the two approach each other, gradually offsetting part of the potential energy generated by the collision. Second, when the collision potential energy is greater, the repulsive force will also be greater. At this time, the back plate 301 will squeeze the rubber block 302, and the force acting on one side of the rubber block 302 will cause the rubber block 302 to deform. The elastic deformation of the rubber block 302 will absorb and disperse the potential energy generated by the collision. Third, after hitting the insulating plate 304, the insulating plate 304 will move, and the spring 306 will be compressed. The compressed spring 306 will generate a rebound force under the action of its own restoring force. The rebound force acts on one side of the insulating plate 304, offsetting part of the potential energy generated by the collision. Therefore, during the collision, the various structures can cooperate with each other to disperse the potential energy of the collision. Example

[0027] Based on the first embodiment, a cleaning mechanism is provided on one side of the slider 2. The cleaning mechanism includes a side plate 201, a cotton brush 202, and a hexagonal nut 203. The side plate 201 is provided on one side of the slider 2 and is detachable. The side plate 201 is fixed to the side of the slider 2 by four hexagonal nuts 203. Removing the hexagonal nuts 203 disassembles the side plate 201 and cleans the cotton brush 202. The hexagonal nuts 203 are provided on one side of the side plate 201, and the cotton brush 202 is provided on the other side of the side plate 201. When the device is in operation, the slider 2 drives the cotton brush 202 to move. At this time, the cotton brush 202, which contacts the inner wall of the housing 1, cleans the inner wall of the housing 1, keeping the inner wall of the housing 1 clean and preventing the accumulation of dirt and oil that would significantly hinder the movement of the slider 2.

[0028] A mounting plate 5 is fixedly connected to the top of the slide rail 3 , a screw rod 4 is rotatably connected to one side of the mounting plate 5 , and a motor 6 is provided on the other side of the mounting plate 5 .

[0029] Working principle:

[0030] First, through the provided buffer mechanism, when the slider 2 is about to collide uncontrollably, first, the slider 2 contacts the insulating plate 304. At this time, the magnetic plate provided on one side of the insulating plate 304, which repels the magnetic plate 308, will generate a mutually repulsive force when the two approach each other, gradually offsetting a portion of the potential energy generated by the collision. Secondly, when the collision potential energy is greater, the repulsive force will also be greater. At this time, the back plate 301 will squeeze the rubber block 302, and the force acting on one side of the rubber block 302 will cause the rubber block 302 to deform. The elastic deformation of the rubber block 302 will absorb and disperse the potential energy generated by the collision. Finally, after hitting the insulating plate 304, the insulating plate 304 will move, and the spring 306 will be compressed. The compressed spring 306 will generate a rebound force under the action of its own restoring force. The rebound force acts on one side of the insulating plate 304, offsetting a portion of the potential energy generated by the collision. Therefore, during the collision, the various structures can cooperate with each other to disperse the potential energy of the collision and will not damage the module parts.

[0031] Furthermore, through the cleaning mechanism, when the device is working, the slider 2 drives the cotton brush 202 to move. At this time, the cotton brush 202 in contact with the inner wall of the shell 1 will clean the inner wall of the shell 1, so that the inner wall of the shell 1 remains clean, avoiding the accumulation of dirt and oil, which will cause greater obstruction when the slider 2 moves.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.
