Description

Technical Field

[0001] This application relates to the field of linear modules, and more particularly to a lubrication injection component and a linear module. Background Technology

[0002] Fully enclosed modules, as core transmission components in automated equipment, are widely used in precision manufacturing, semiconductor processing, and other fields due to their excellent sealing and operational stability. However, these modules generally face the problem of insufficient maintainability during long-term use, especially in the lubrication maintenance of moving parts. Because the module adopts an integrated sealed structure design, its core components such as the mover slide and guide rail slider are completely enclosed inside a protective shell. Traditional lubrication operations require manually removing external components such as end plates and side covers to expose the internal oil filling points. This maintenance method not only requires interrupting equipment operation but also suffers from the drawbacks of cumbersome disassembly procedures, time-consuming, and labor-intensive. Operators often need to use specialized tools to remove more than ten fasteners one by one, and even slight carelessness can lead to deformation of the seals or stripping of threads, thus posing a risk of secondary seal failure. Frequent disassembly operations also accelerate the mechanical wear of connecting components, causing problems such as increased clearance and reduced dustproof performance, seriously affecting the module's transmission accuracy and service life. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a lubrication injection component and a linear module.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides:

[0006] A lubrication injection assembly, comprising:

[0007] An oil passage is provided inside the mover slide, the oil passage having a first opening and a second opening. The first opening communicates with the outside of the mover slide, the slider at the bottom of the mover slide has an oil inlet, and the second opening communicates with the oil inlet. The first opening delivers lubricating oil through the oil passage to the oil inlet to lubricate the slider.

[0008] Furthermore, an oil injection nozzle is installed at the first opening, and a first connector is installed at the second opening.

[0009] Furthermore, a second connector is installed at the oil inlet, and the second connector is connected to the first connector.

[0010] Furthermore, the first connector is connected to an oil pipe, and the end of the oil pipe away from the first connector is connected to the second connector.

[0011] Furthermore, the oil circuit includes a first channel formed inside the mover slide along a first direction, the first channel extending to the side wall of the mover slide, the oil nozzle being installed in the opening of the first channel on the side wall of the mover slide, a second channel being formed at the end of the first channel away from the direction of the oil nozzle along a second direction, a third channel being formed at the end of the second channel away from the direction of the first channel along a third direction, a fourth channel being formed at the end of the third channel away from the direction of the second channel along a first direction, a fifth channel being formed at the end of the fourth channel away from the direction of the third channel along a third direction, and the first connector being installed in the opening of the fifth channel away from the direction of the fourth channel.

[0012] This application also provides a linear module, including:

[0013] A base, on which a guide rail is fixedly mounted;

[0014] A moving slide, wherein the moving slide is mounted on the base, and the oil passage of the lubrication and oil injection assembly described in any of the above-mentioned embodiments is opened inside the moving slide;

[0015] A slider is slidably mounted on the guide rail, and the side of the slider away from the guide rail is fixedly connected to the moving slide table;

[0016] A first side baffle is fixedly installed at both ends of the base;

[0017] The second side baffle is located on both sides of the base and is perpendicular to the first side baffle. The base, the first side baffle, and the second side baffle define a mounting cavity.

[0018] A steel strip, the two ends of which are respectively connected to the first side baffle, is used to seal the mounting cavity.

[0019] Furthermore, the moving slide includes a first slide and a second slide, the second slide is fixedly installed on one side of the first slide, the oil passage is opened in the first slide, and the second slide is connected to each of the sliders.

[0020] Furthermore, the first slide table includes a table body, with first guide rollers rotatably mounted at both ends of the table body, and a second guide roller rotatably mounted on the table body, the second guide roller being located between the two first guide rollers, and the steel strip being wound around the first guide roller and the second guide roller respectively.

[0021] Furthermore, an inclined surface is provided on the platform in the area from the second guide roller to the first guide roller, and a preset angle is defined between the two inclined surfaces.

[0022] Furthermore, a cover plate is installed on the first slide, the cover plate having a covering cavity, and the first slide is located inside the covering cavity.

[0023] This application solves the problems of cumbersome procedures, damage to seals, and reduced transmission accuracy caused by repeated disassembly of the outer shell during maintenance of fully enclosed modules. By opening an oil passage inside the moving slide table that connects to the outside and the oil inlet of the slider, the operator can inject lubricating oil into the oil passage through the first opening without disassembling the first and second side baffles of the linear module. The lubricating oil is directly delivered to the slider through the second opening of the oil passage. This solves the problems of cumbersome procedures, damage to seals, and reduced transmission accuracy caused by repeated disassembly and assembly during maintenance of fully enclosed modules. The cooperation between the external oil nozzle and the internal oil passage achieves disassembly-free maintenance, which significantly improves the efficiency of lubrication maintenance while ensuring sealing performance. It effectively avoids problems such as thread stripping and seal failure caused by frequent disassembly and assembly, and extends the service life of the guide rail and slider mating surface.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0039] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0041] This application provides a lubrication injection assembly, which includes an oil passage 120 opened inside a mover slide 100. The oil passage 120 has a first opening and a second opening. The first opening communicates with the outside of the mover slide 100. The slider 200 at the bottom of the mover slide 100 has an oil inlet. The second opening communicates with the oil inlet. The first opening delivers lubricating oil through the oil passage 120 to the oil inlet to lubricate the slider 200.

[0042] See Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, when it is necessary to inject lubricating oil into the slider 200, firstly, lubricating oil is injected through the first opening of the oil passage 120. Under the guidance of the oil passage 120, the lubricating oil is transported to the second opening position, then the lubricating oil is transported to the oil inlet of the slider 200, and finally the lubricating oil is transported into the slider 200 to achieve lubrication.

[0043] It is understandable that since the first opening of the oil circuit 120 is connected to the outside of the moving slide 100, the lubricating oil can be delivered to the oil circuit 120 from the outside through the first opening. The lubricating oil can be delivered to the upper part of the line formed by the first opening, the oil circuit 120, the second opening and the oil inlet without removing the outer shell of the linear module. This makes it more convenient and faster to inject lubricating oil into the slider 200 and improves the efficiency of lubricating oil injection.

[0044] An oil nozzle 110 is installed at the first opening, and a first connector 130 is installed at the second opening; a second connector 210 is installed at the oil inlet, and the second connector 210 is connected to the first connector 130; an oil pipe is connected to the first connector 130, and the end of the oil pipe away from the first connector 130 is connected to the second connector 210.

[0045] Please continue reading. Figures 1 to 4 As shown, in order to deliver lubricating oil from oil passage 120 to slider 200, a second connector 210 is installed at the oil inlet (not shown) of slider 200, and a first connector 130 is installed at the second opening of oil passage 120. The first connector 130 and the second connector 210 are connected by a compatible oil pipe (not shown). It can be understood that the passage formed by oil passage 120, first connector 130, oil pipe and second connector 210 can realize the delivery of lubricating oil to slider 200 for lubrication.

[0046] Furthermore, when injecting oil, a special tool such as an oil gun can be used to aim at the oil nozzle 110 and inject the lubricating oil into the oil passage 120. The lubricating oil will then flow into the slider 200 along the oil passage 120 and the oil pipe, thus realizing the injection of lubricating oil and enabling the slider 200 to be injected with lubricating oil directly from outside the linear module.

[0047] For example, the first and second openings of the oil passage 120 and the oil inlet of the slider 200 can all be provided with corresponding internal threads. Accordingly, the oil nozzle 110 can be installed at the first opening by means of a threaded connection, the first connector 130 can be installed at the second opening by means of a threaded connection, and the second connector 210 can be installed at the oil inlet by means of a threaded connection. It should be noted that when making threaded connections, appropriate Teflon tape should be provided at the connection to further achieve sealing, thereby preventing lubricating oil from leaking from the connection. Threaded connections enable the quick installation of various components and make disassembly and maintenance more convenient.

[0048] The oil passage 120 includes a first channel 121 opened inside the mover slide 100 along a first direction. The first channel 121 extends to the side wall of the mover slide 100. An oil nozzle 110 is installed in the opening of the first channel 121 located on the side wall of the mover slide 100. A second channel 122 is opened along a second direction at the end of the first channel 121 away from the direction of the oil nozzle 110. A third channel 123 is opened along a third direction at the end of the second channel 122 away from the direction of the first channel 121. A fourth channel 124 is opened along the first direction at the end of the third channel 123 away from the direction of the second channel 122. A fifth channel 125 is opened along a third direction at the end of the fourth channel 124 away from the direction of the third channel 123. A first connector 130 is installed in the opening of the fifth channel 125 away from the direction of the fourth channel 124.

[0049] Please see Figure 2 and Figure 3 As shown, when lubricating oil needs to be injected, the lubricating oil first enters the first channel 121 through the oil nozzle 110, and then enters the second channel 122, the third channel 123, the fourth channel 124 and the fifth channel 125 in sequence. Finally, it enters the slider 200 through the oil pipe through the first connector 130 located at the opening of the fifth channel 125, thereby realizing the delivery of lubricating oil.

[0050] It should be noted that the first direction mentioned above is the horizontal direction, that is... Figure 2 The X direction shown is the first direction, and the second direction is the height direction, which is... Figure 2 The Z direction shown is the third direction, which is the longitudinal direction. Figure 2 As shown in the Y direction, it should be noted that the direction of each channel in this application can be designed according to actual needs. This is just an example and is not limited to any specific application.

[0051] It is understandable that the first opening of the oil passage 120 is the opening that connects the first channel 121 to the outside, and the second opening is the opening that connects the fifth channel 125 to the first connector 130.

[0052] Furthermore, generally speaking, the bottom of the mover slide 100 usually has four sliders 200. Accordingly, oil passages 120 should be opened on both sides of the front and rear ends of the mover slide 100, and each oil passage 120 has two second openings, that is, each oil passage 120 should be connected to two first connectors 130. Each first connector 130 is connected to its second connector 210 at its position through an oil pipe to provide lubricating oil to the slider 200 at its position. The layout of the oil passages 120 on the mover slide 100 can be found in [reference needed]. Figure 2 as well as Figure 3 As shown.

[0053] This application embodiment also provides a linear module, which includes a base, a mover slide 100, a slider 200, a first side baffle 300, a second side baffle 400, and a steel strip 500. Specifically, a guide rail 201 is fixedly installed on the base, the mover slide 100 is installed on the base, the oil passage 120 of any of the above-mentioned lubrication and oil injection components is opened inside the mover slide 100, the slider 200 is slidably installed on the guide rail 201, the side of the slider 200 away from the guide rail 201 is fixedly connected to the mover slide 100, the first side baffle 300 is fixedly installed at both ends of the base, the second side baffle 400 is located on both sides of the base, and the second side baffle 400 is perpendicularly arranged with the first side baffle 300. The base, the first side baffle 300, and the second side baffle 400 define an installation cavity, and the two ends of the steel strip 500 are respectively connected to the first side baffle 300. The steel strip 500 is used to close the installation cavity.

[0054] Please see Figure 5 As shown, in order to prevent external dust from entering the interior of the linear module and damaging its internal components, first side baffles 300 are fixedly installed at both ends of the base. Furthermore, second side baffles 400 are fixedly installed on both sides of the base, and the second side baffles 400 are fixedly connected to the first side baffles 300 at both ends. At this time, the base, the two first side baffles 300 and the two second side baffles 400 define an installation cavity. The slider 200, guide rail 201, mover slide 100, second connector 210, first connector 130 and oil pipe are all located in the installation cavity. A steel strip 500 is set at the upper opening of the installation cavity to seal it, thereby preventing external dust from entering the installation cavity and thus achieving complete sealing of the linear module.

[0055] The moving slide 100 includes a first slide 101 and a second slide 102. The second slide 102 is fixedly installed on one side of the first slide 101. An oil passage 120 is opened in the first slide 101. The second slide 102 is connected to each slider 200.

[0056] Please see Figure 5 , Figure 8 As shown, the first slide 101 is mounted on the second slide 102, and the second slide 102 is fixedly connected to each slider 200, so that the first slide 101 can slide along the track of the guide rail 201.

[0057] The first slide table 101 includes a table body 1011. First guide rollers 1012 are rotatably mounted on both ends of the table body 1011. A second guide roller 1013 is also rotatably mounted on the table body 1011. The second guide roller 1013 is located between the two first guide rollers 1012. The steel strip 500 is wound around the first guide roller 1012 and the second guide roller 1013 respectively.

[0058] Please see Figure 6 As shown, in order to ensure that the steel strip 500 can also close the mounting cavity during the sliding process of the platform 1011, firstly, first guide rollers 1012 are rotatably installed at both ends of the platform 1011, and a second guide roller 1013 is rotatably installed at the middle position of the two first guide rollers 1012. Next, the steel strip 500 winds around the two first guide rollers 1012 and the second guide roller 1013. Specifically, according to... Figure 6 As shown, the steel strip 500 is wound around the lower circumferential portion of the two first guide rollers 1012 and then around the upper circumferential portion of the second guide roller 1013, so that the steel strip 500 can pass through the platform 1011 during the movement.

[0059] It should be noted that the steel strip 500 can undergo a certain deformation, thereby adjusting for the height difference caused by the different winding positions of the first guide roller 1012 and the second guide roller 1013.

[0060] An inclined surface 1014 is provided on the platform 1011 in the area from the second guide roller 1013 to the first guide roller 1012, and a preset angle is defined between the two inclined surfaces 1014.

[0061] Please continue reading. Figure 6 As shown, to prevent the steel strip 500 from directly contacting its upper surface and causing motion interference during the movement of the platform 1011, an inclined surface 1014 is provided in the area between the second guide roller 1013 and the two first guide rollers 1012. The slope of the inclined surface 1014 is used to avoid the steel strip 500 and prevent the steel strip 500 from directly contacting the platform 1011.

[0062] A cover plate 600 is installed on the first slide 101. The cover plate 600 has a covering cavity, and the first slide 101 is located inside the covering cavity.

[0063] Please see Figure 5 , Figure 7 as well as Figure 8 As shown, in order to prevent external objects from entering the upper surface of the first slide table 101, a cover plate 600 is installed on the first slide table 101 to cover it. Specifically, the cover plate 600 is fixedly installed on the table body 1011.
