[0035] Currently, robot track technology has reached a relatively mature stage and is widely used in industrial automated production lines, warehousing and logistics, precision manufacturing, and other fields, providing stable track support for the precise movement and efficient operation of robots. In practical applications, some robot tracks need to cope with complex environments such as dust, humidity changes, and minor impacts; therefore, high-protection-level tracks have become a key requirement in specific scenarios.

[0036] For the lubrication needs of high-protection robot tracks, the mainstream and widely used lubrication solution in the industry is currently the electric lubricator. This lubrication solution uses an electric drive device to automatically deliver and distribute the lubricating medium, adapting to the structural design characteristics of high-protection tracks. It can work synergistically with the track's protection system to effectively prevent external impurities from entering the lubrication points. In terms of performance advantages, the most prominent feature of this electric lubrication solution under this structural protection is its high degree of automation. It can reduce the need for manual periodic lubrication, lowering manual intervention costs, while also ensuring the timeliness and continuity of lubrication operations to a certain extent.

[0037] However, problems exist in practical applications. The electric lubricator generates noise during operation, which can easily interfere with the operation of surrounding equipment and the work of operators, especially in precision manufacturing scenarios where noise requirements are high. Furthermore, the lubricator suffers from uneven oil distribution. Affected by factors such as the viscosity of the lubricating medium, the layout of the delivery pipeline, and the stability of the electric drive pressure, some rail lubrication points may experience insufficient or excessive lubrication, affecting the uniform lubrication effect of various components of the ground rail.

[0038] In order to solve the technical problems involved in the above background art, such as Figure 1 , Figure 2 As shown, this application provides a lubrication structure suitable for lubricating ground rail devices, including a lubrication pump 100, which is used to drive the lubricating medium to be output from the output end of the lubrication pump 100 through elastic potential energy.

[0039] Oil distribution assembly 200 is connected to the output end of lubrication pump 100. Oil distribution assembly 200 is used to distribute lubricating medium to at least two lubrication points.

[0040] The lubrication pump 100 includes a resettable elastic element and a pump body connected to the elastic element. The pump body achieves controllable output of the lubricating medium through the reset action of the elastic element.

[0041] It should be noted that the lubrication pump 100 adopts a drive structure that combines a resettable elastic element with the pump body, using elastic potential energy to replace electric drive and eliminating the noise generated by the electric motor in the electric lubricator. The design without electric components simplifies the structure, reduces potential failure points, and eliminates the need to disassemble the complex electric module for subsequent maintenance, improving maintenance convenience. Furthermore, the reset action of the elastic element can precisely control the rate and dosage of lubricating medium output from the pump body, avoiding excessive or insufficient lubrication caused by pressure fluctuations in the electric drive, thus achieving controllable output of the lubricating medium.

[0042] It should also be noted that the elastic element stores elastic potential energy through pre-compression or stretching in its initial state, at which point the internal chamber of the pump body is in a stable, ready-to-output state. When lubrication needs to be started, the constraint condition of the elastic element is released, and it releases its elastic potential energy in a preset direction, generating a reset force that directly drives the moving parts inside the pump body, such as the piston and diaphragm. When the elastic element in this application is a compression spring, during the reset process, the spring pushes the piston to move in the direction of decreasing chamber volume, squeezing the lubricating medium inside the chamber to give the medium the pressure to be output outward, and finally discharging it from the output end of the lubrication pump 100. The entire process does not rely on electric components such as motors and circuits, but is achieved entirely through mechanical force transmission, thus avoiding the noise and circuit failure risks caused by electric drive from the source.

[0043] Furthermore, the oil distribution component 200 is directly connected to the output end of the lubrication pump 100 and has the function of distributing the lubricating medium to at least two lubrication points, which can adapt to the needs of multiple lubrication points in the ground rail device. This component can evenly distribute the lubricating medium through its internal flow channel design, effectively solving the problem of uneven oil distribution in existing electro-lubrication solutions, ensuring that each lubrication point of the ground rail can obtain sufficient and uniform lubrication, and avoiding wear of local parts due to insufficient lubrication or waste caused by excessive lubrication.

[0044] Furthermore, the entire lubrication structure does not rely on external power; lubrication is accomplished solely through the mechanical movement of elastic elements. This not only makes it suitable for the enclosed environment of high-protection ground rails, eliminating the need for additional power interfaces, but also reduces interference from external factors. Simultaneously, the simple mechanical structure and clear division of labor among components—with the lubrication pump 100 responsible for output and the oil distribution assembly 200 responsible for distribution—makes the overall installation and maintenance process more convenient.

[0045] According to one embodiment of this application, the oil distribution assembly 200 includes an oil distributor 210. A plurality of oil delivery pipes 220 are spaced apart on the outside of the oil distributor 210. A pressure equalization component provided inside the oil distributor 210 evenly distributes the lubricating medium into at least two oil delivery pipes 220. The at least two oil delivery pipes 220 deliver the lubricating medium to at least two lubrication points.

[0046] It should be noted that the pressure equalization components within the distributor 210 include a flow-dividing chamber and a pressure balancing channel, used to balance the pressure of the lubricating medium after it enters the distributor 210. When the lubricating medium output from the lubrication pump 100 enters the distributor 210, the pressure equalization components can quickly eliminate the pressure difference of the medium within the chamber, avoiding the problem of more medium near the inlet end and less medium far from the inlet end caused by differences in the length of the medium flow path and the resistance of the pipeline. This ensures that the medium pressure and flow rate obtained by each oil delivery pipe 220 are consistent. This uniform distribution effect allows each lubrication point of the ground rail to receive a sufficient and equal amount of lubricating medium, avoiding dry friction wear due to insufficient medium at local lubrication points, and preventing waste or contamination due to excessive medium in some areas, thus improving the lubrication consistency of various components of the ground rail.

[0047] Furthermore, the multiple oil delivery pipes 220 spaced apart on the outer side of the oil distributor 210 can be flexibly arranged according to the number and distribution of lubrication points in the ground rail device, directly adapting to the needs of multiple dispersed lubrication points in the ground rail. Simultaneously, the spaced arrangement prevents the oil delivery pipes 220 from tangling or being squeezed together, reducing the risk of pipe damage due to contact friction. The oil delivery pipes 220 are directly connected to the oil distributor 210, and a valve body is provided at the end of the oil distributor 210, thereby shortening the transport path of the medium from the oil distributor 210 to the lubrication points and reducing pressure loss of the medium during transport.

[0048] According to one embodiment of this application, it further includes a plurality of first sliders 300, the first sliders 300 being connected to the oil distribution assembly 200, each pair of first sliders 300 forming a slider group, and each pair of first sliders 300 having a lubrication point at their mutually distant ends, and the oil distribution assembly 200 being connected to the lubrication point via a pipeline.

[0049] It should be noted that each pair of first sliders 300 forms a slider group, and each pair of first sliders 300 within each group has a lubricant receiving channel, i.e., a lubrication point, located at the far ends. When the ground rail is running, the far ends of the first sliders 300 are usually close to the contact area between the slider and the guide rail, the sealing area, and other core lubrication points. Placing the receiving channel at this location can minimize the transmission distance from the receiving channel to the actual lubrication point, reduce the risk of lubricant leakage and flow loss during the transfer process, and ensure that the lubricant received by the receiving channel can be quickly and directly delivered to the target lubrication area. At the same time, the grouping method of each pair is suitable for the common symmetrical layout of ground rail sliders, such as the sliders arranged in pairs on both sides of the ground rail in this application. This makes the receiving channels symmetrically distributed, which can simultaneously provide balanced lubricant to the actual lubrication points on both sides, and prevent local lubrication deficiency caused by insufficient lubrication supply on one side.

[0050] The oil distribution component 200 is connected to each lubrication point via a corresponding pipeline. The lubricating fluid distributed by the oil distribution component 200 to each channel can directly reach the corresponding receiving channel through the pipeline. This prevents situations where one channel receives too much fluid and another channel receives too little fluid due to pressure fluctuations or uneven flow distribution within the pipeline. This further enhances the uniform distribution effect of the oil distribution component 200 and ensures that each receiving channel can stably receive a fixed amount of lubricating fluid.

[0051] According to one embodiment of this application, a groove 320 is provided on one side of the first slider 300. The groove 320 extends through the front and rear ends of the first slider 300. A plurality of oil outlet holes are provided on the surface of the groove 320. The oil outlet holes are used to release the lubricating medium inside the first slider 300.

[0052] It should be noted that the groove 320 penetrates the front and rear ends of the first slider 300, forming a through channel along the slider's movement direction. When the lubricating medium enters the first slider 300 through the internal channel, the medium first diffuses in the groove 320 in the front-to-back direction, avoiding uneven precipitation caused by local medium accumulation. When the slider moves, the medium in the groove 320 can extend forward and backward with the slider displacement, solving the problem that single-point oil outlets can only cover a local area, ensuring that the contact surfaces between the slider and the guide rail can all contact the lubricating medium, and improving the overall lubrication coverage.

[0053] Furthermore, the first slider 300 is a moving part of the ground rail. When the slider slides, the medium released from the oil outlet hole will be carried up by the relative movement between the guide rail surface and the slider, forming a continuous lubricating film on the contact surface; while the medium temporarily stored in the groove 320 will be continuously replenished through the oil outlet hole as the slider moves.

[0054] According to one embodiment of this application, a base is provided on one side of the slider group, the slider group is symmetrically arranged along the central axis of the base, and connecting parts 510 are provided on the left and right sides of the base. The groove 320 of the first slider 300 is nested and connected with the connecting parts 510, and the first slider 300 can slide relative to the base.

[0055] It should be noted that the slider assembly is symmetrically distributed along the central axis of the base, which allows the load of the ground rail to be evenly distributed on both sides of the first slider 300 during operation. Furthermore, the groove 320 has a claw-like structure, which avoids uneven load distribution caused by excessive force on one side of the slider. This symmetrical layout balances the friction between the slider assembly and the base, preventing the first slider 300 from jamming, tilting, or experiencing excessive wear due to uneven force during sliding. This ensures smooth movement of the slider assembly along the base and improves the overall operational stability and motion accuracy of the ground rail.

[0056] According to one embodiment of this application, the lubrication gear 400 is further included. The lubrication gear 400 includes a first column 410. A pair of gear components are sleeved on the outer side of the first column 410. An input interface is provided on the side of the first column 410. The input interface is connected to the oil distribution component 200. An oil drain port is provided at the position of the gear component on the first column 410. When the gear component rotates, the oil drain port outputs lubricating medium.

[0057] It should be noted that the oil drain port is located at the gear component position of the first column 410, and outputs lubricating medium when the gear component rotates. When the gear component rotates, it is in working condition, and the gear meshing or friction is most intense. The oil drain port outputs medium synchronously, which directly acts on the meshing surface, tooth root, or shaft hole and other friction parts of the gear.

[0058] According to one embodiment of this application, a gear rack component 600 is provided on one side of the lubrication gear 400. The gear rack component 600 is meshed with the lubrication gear 400. The gear rack component 600 is located on one side of the base. The gear rack component 600 rotates to drive the base to move.

[0059] It should be noted that when the gear and rack component 600 meshes with the lubricating gear 400, it is within the effective range of the oil drain port of the lubricating gear 400. While the gear and rack component 600 drives the lubricating gear 400, the lubricating medium output from its oil drain port can directly act on the meshing surface of both, i.e., the tooth contact area. During gear and rack meshing friction, a continuous lubricating film is formed, effectively reducing tooth surface wear, reducing transmission noise, preventing tooth breakage or jamming caused by dry friction, and extending the service life of both the gear and rack component 600 and the lubricating gear 400.

[0060] According to one embodiment of this application, a bracket 110 is provided at the output end of the lubrication pump 100, and a connector assembly 120 is provided at the output end of the lubrication pump 100. A portion of the connector assembly 120 passes through the bracket 110, and an oil delivery pipe is connected to the end of the connector assembly 120. The oil delivery pipe is connected to the input end of the oil distribution assembly 200.

[0061] It should be noted that the bracket 110 is located at the output end of the lubrication pump 100, providing rigid support and positioning for the lubrication pump output end and the connector assembly 120 passing through it. The bracket 110 can withstand the vibration generated by the elastic element resetting and driving the pump body during the operation of the lubrication pump 100, preventing the lubrication pump output end from shifting or tilting due to vibration, ensuring that the interface between the connector assembly 120 and the lubrication pump output end is always aligned, and preventing media leakage or poor transmission due to interface misalignment. Furthermore, the bracket 110 can limit the installation position of the connector assembly 120, preventing the connector assembly 120 from shifting due to external pulling, providing a precise docking reference for the subsequent connection of the oil pipeline, and reducing the position adjustment time during assembly.

[0062] This application also provides a ground rail structure, including a motor assembly 700, a reducer 710 connected to the output end of the motor assembly 700, a gear rack component 600 connected to the output end of the reducer 710, a base connected to one side of the gear rack component 600, and a trolley sleeved and connected to the outer side of the base. The motor assembly 700 controls the gear rack component 600 to rotate so as to drive the trolley to move.

[0063] According to one embodiment of this application, a lubrication pump 100 is disposed on one side of a motor assembly 700. When the motor assembly 700 is started, the lubrication pump 100 continuously delivers lubricating medium to the oil distribution assembly 200.

[0064] It should be noted that when the motor assembly 700 starts, it drives the reducer 710 and the gear and rack assembly 600 to rotate, thereby driving the base and the trolley to move. At this time, the trolley slides, the gear and rack mesh, and the lubrication pump 100 supplies liquid synchronously and continuously. The medium can be distributed to key lubrication points such as the oil outlet of the first slider 300 and the oil drain port of the lubrication gear 400 through the oil distribution assembly 200, ensuring that the moving parts have sufficient medium support during the friction stage, and avoiding the temporary dry friction wear caused by the parts running first after the motor starts and the lubrication lagging behind.
