Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts processing and molding technology, and in particular relates to an oil injection and glue dispensing device. Background Technology
[0002] In traditional automobile manufacturing processes, lubrication and adhesive application are typically handled by two separate sets of equipment. The lubrication equipment is primarily used to apply lubricating oil or grease to moving parts such as bearings and gears. Its core structure includes a high-pressure pumping system, a metering control valve, and corrosion-resistant piping. The adhesive application equipment, on the other hand, is responsible for applying sealant or adhesive to areas such as body welds and electronic component joints, relying on precision metering pumps, multi-axis robotic arms, and non-contact spray valves to achieve high-precision coating. Functionally, the two sets of equipment have distinct roles: lubrication focuses on lubrication and rust prevention, while adhesive application focuses on sealing and bonding. Both are critical steps in the automobile assembly process.
[0003] However, the traditional separate-equipment operation mode has significant drawbacks. Because the oiling and dispensing equipment operate independently, even when both are working at the same processing location (e.g., the gearbox housing requires oiling before sealing), separate workpiece positioning, fixture adjustment, and equipment start-up and shutdown operations are still necessary. This repetitive positioning not only increases production cycle time but also easily leads to problems such as missed coating, glue overflow, or uneven lubrication due to positioning deviations. Furthermore, there is a risk of material contamination during equipment changeover (e.g., residual lubricating oil affecting adhesive bonding), while also occupying more factory space and increasing maintenance costs. The efficiency bottlenecks and quality risks caused by process fragmentation have become prominent pain points in the intelligent upgrading of automobile manufacturing. Utility Model Content
[0004] The purpose of this utility model is to provide an oil and glue dispensing device, which aims to solve the technical problems in the existing automotive oil and glue dispensing processes. Because the oil and glue dispensing equipment operate independently, even if the two are working at the same processing position, workpiece positioning, fixture adjustment and equipment start-up and shutdown operations are still required separately. This repeated positioning not only increases the production cycle time, but also easily leads to the technical problems of missed coating, glue overflow or uneven lubrication due to positioning deviation.
[0005] To achieve the above objectives, this utility model provides an oil and glue dispensing device, comprising an oil injection mechanism, a glue dispensing mechanism, a cleaning mechanism, and a four-way mechanism. The four-way mechanism is used to deliver lubricating oil to a preset position on the workpiece to be processed; to deliver sealing liquid to a preset position on the workpiece; and to output a cleaning agent to remove oil stains and residual glue. The four-way mechanism includes an oil injection channel, a glue dispensing channel, a cleaning channel, and an output channel. The oil injection channel, glue dispensing channel, and cleaning channel are respectively connected to the output ends of the oil injection mechanism, the glue dispensing mechanism, and the cleaning mechanism. The outlet of the output channel faces the workpiece to be processed. The output ends of the oil injection channel and the glue dispensing channel are connected to the output channel. The cleaning channel has two sets of output ends, each set connected to both the oil injection channel and the glue dispensing channel.
[0006] Optionally, it also includes a mounting base plate, on which the oil injection mechanism, the glue dispensing mechanism and the cleaning mechanism are all disposed. The mounting base plate is driven by an external multi-axis moving mechanism to move to a preset processing position of the device to be processed.
[0007] Optionally, the four-way mechanism includes a base, a first connecting seat, a second connecting seat, and a third connecting seat. The first connecting seat and the second connecting seat are symmetrically distributed at both ends of the base. The third connecting seat is formed on the base and located between the first connecting seat and the second connecting seat. The oil injection channel and the glue injection channel are respectively formed in the first connecting seat and the second connecting seat. The cleaning channel is formed in the third connecting seat. The output channel is formed in the base. An extension pipe is provided at the end of the base away from the first connecting seat, the second connecting seat, and the third connecting seat. The input end of the extension pipe is connected to the output channel.
[0008] Optionally, both the oil injection channel and the glue injection channel are equipped with a first one-way valve at their output ends, and the liquid materials output by the oil injection mechanism and the glue dispensing mechanism are transported to the output channel through the corresponding first one-way valve.
[0009] Optionally, the cleaning channel includes an input section and an output section, and there are two sets of output sections. The input ends of both sets of output sections are connected to the input section, and the two sets of output sections are bent and extended and connected to the output ends of the oil injection channel and the glue injection channel, respectively.
[0010] Optionally, the output ends of the two sets of output segments are located between the first one-way valve and the output channel.
[0011] Optionally, a second check valve is provided at the output end of both sets of output sections.
[0012] Optionally, the output channel includes a connecting groove and a confluence groove. There are two sets of connecting grooves, and the two sets of connecting grooves are respectively connected to the oil injection channel and the glue injection channel. The output ends of the two sets of connecting grooves are connected to the confluence groove.
[0013] Optionally, a MEMS flow sensor is provided on the inner wall of the output end of the confluence channel.
[0014] Optionally, the oil injection mechanism is connected to an external lubricating oil supply system pipeline, the glue dispensing mechanism is connected to an external sealant supply system pipeline, and the cleaning mechanism has two sets of input ends, which are respectively connected to an external oil stain cleaner supply system and a residual adhesive cleaner supply system pipeline.
[0015] The oil injection and dispensing equipment provided in this utility model embodiment has at least one of the following technical effects: This integrated design combines oil injection, dispensing, and cleaning functions into a single distributor, and allows liquid materials to be alternately output from the same pipe outlet, significantly improving process continuity and production efficiency. Its core advantage lies in avoiding the repetitive positioning and start-up / stop operations required during traditional multi-device switching. The built-in cleaning mechanism removes pipe residues in real time, eliminating the risk of cross-contamination between lubricating oil and adhesive, reducing equipment space requirements and maintenance complexity, while ensuring high precision and consistency in the oil injection and dispensing processes. It is particularly suitable for precision manufacturing scenarios of automotive parts where process connections and cleanliness requirements are stringent. Attached Figure Description

The following description is based on the accompanying drawings. Figures 1-4 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.
[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0030] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0031] In this embodiment of the invention, unless otherwise explicitly 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. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0032] In one embodiment of this utility model, such as Figures 1-4 As shown, an oil and glue dispensing device is provided, including an oil injection mechanism 100, a glue dispensing mechanism 200, a cleaning mechanism 300, and a four-way mechanism 400. The device is used to deliver lubricating oil to a preset position on the workpiece to be processed; to deliver sealing liquid to a preset position on the workpiece; and to output a cleaning agent to remove oil stains and residual glue. The four-way mechanism 400 is provided with an oil injection channel 410, a glue dispensing channel 420, a cleaning channel 430, and an output channel 440. The oil injection channel 410, glue dispensing channel 420, and cleaning channel 430 are respectively connected to the output ends of the oil injection mechanism 100, the glue dispensing mechanism 200, and the cleaning mechanism 300. The outlet of the output channel 440 faces the workpiece to be processed. The output ends of the oil injection channel 410 and the glue dispensing channel 420 are connected to the output channel 440. The cleaning channel 430 has two sets of output ends, each set connected to the oil injection channel 410 and the glue dispensing channel 420.
[0033] Specifically, the oil injection mechanism 100, the adhesive dispensing mechanism 200, and the cleaning mechanism 300 are all gun-type liquid injection structures. This structure is technically mature and will not be described in detail in this embodiment. In this embodiment, the oil injection mechanism 100 is used to deliver lubricating grease to the vehicle transmission or starter motor gearbox, and the adhesive dispensing mechanism 200 is used to deliver adhesive to the edge of the cover to seal the grease inside the corresponding compartment. The cleaning mechanism 300 delivers a cleaning agent that is both a sealant remover and an oil remover. The cleaning mechanism 300 delivers a preset cleaning agent to the output channel 440 as needed to prevent grease and adhesive from mixing and contaminating each other.
[0034] This integrated design combines oiling, dispensing, and cleaning functions into a single distributor, allowing liquid materials to be alternately output from the same pipe outlet, significantly improving process continuity and production efficiency. Its core advantage lies in avoiding the repetitive positioning and start-stop operations required during traditional multi-device switching. The built-in cleaning mechanism removes pipe residues in real time, eliminating the risk of cross-contamination between lubricating oil and adhesive, reducing equipment space requirements and maintenance complexity, while ensuring high precision and consistency in the oiling and dispensing processes. This makes it particularly suitable for precision manufacturing scenarios in automotive parts where stringent process continuity and cleanliness requirements are essential.
[0035] like Figures 1-4 As shown, in another embodiment of this utility model, the oil injection and dispensing mechanism 200 further includes a mounting base plate 500. The oil injection mechanism 100, the dispensing mechanism 200, and the cleaning mechanism 300 are all disposed on the mounting base plate 500. The mounting base plate 500 can be moved to a preset processing position of the device to be processed by an external multi-axis moving mechanism. In this embodiment, the external multi-axis moving mechanism XYZ three-axis moving platform adopts a multi-axis structure, which can achieve precise positioning during the oil injection and dispensing process and improve the processing effect.
[0036] like Figures 1-4 As shown, in another embodiment of this utility model, the four-way mechanism 400 includes a base 450, a first connecting seat 460, a second connecting seat 470, and a third connecting seat 480. The first connecting seat 460 and the second connecting seat 470 are symmetrically distributed at both ends of the base 450. The third connecting seat 480 is formed on the base 450 and located between the first connecting seat 460 and the second connecting seat 470. The oil injection channel 410 and the glue injection channel 420 are respectively formed in the first connecting seat 460 and the second connecting seat 470. The cleaning channel 430 is formed in the third connecting seat 480. The output channel 440 is formed in the base 450. An extension pipe is provided at the end of the base 450 away from the first connecting seat 460, the second connecting seat 470, and the third connecting seat 480. The input end of the extension pipe is connected to the output channel 440.
[0037] like Figures 1-4As shown, in this embodiment, the base 450, the first connecting seat 460, the second connecting seat 470, and the third connecting seat 480 are integrally formed by injection molding. Furthermore, the oil injection channel 410, the glue injection channel 420, the cleaning channel 430, and the output channel 440 are integrally formed by injection molding using a stainless steel sleeve. The integral molding method is beneficial to improving the structural stability of the four-way mechanism 400, while the injection molding method is more beneficial to improving the stability of the channels and preventing blockage. At the same time, the stainless steel material is beneficial to preventing liquid materials from sticking to the inner wall of the channels, ensuring the smooth progress of the oil injection and glue dispensing process.
[0038] like Figures 1-4 As shown, in another embodiment of this utility model, both the oil injection channel 410 and the glue injection channel 420 are equipped with a first one-way valve 600 at their output ends. The liquid materials output by the oil injection mechanism 100 and the glue dispensing mechanism 200 are transported to the output channel 440 via the corresponding first one-way valve 600. The use of the first one-way valve 600 structure helps prevent backflow of liquid materials, thus avoiding affecting the accuracy of liquid material input control.
[0039] like Figures 1-4 As shown, in another embodiment of this utility model, the cleaning channel 430 includes an input section and an output section. There are two sets of output sections, with the input ends of both sets connected to the input section. The two sets of output sections are bent and extended, respectively, and connected to the output ends of the oil injection channel 410 and the glue injection channel 420. The two sets of output sections are symmetrically distributed within the third connecting seat 480. The cleaning agent entering from the input section is diverted from the two sets of output sections and delivered to the output ends of the oil injection channel 410 and the glue injection channel 420, thereby cleaning the residue in the oil injection channel 410 and the glue injection channel 420 and preventing contamination.
[0040] like Figures 1-4 As shown, in another embodiment of this utility model, the output ends of the two sets of output sections are located between the first one-way valve 600 and the output channel 440. Using the first one-way valve 600 helps to prevent the cleaning agent or the corresponding liquid material from flowing back and affecting the physical properties of the original liquid material.
[0041] like Figures 1-4 As shown, in another embodiment of this utility model, the output ends of both sets of output sections are provided with a second one-way valve 700. The second one-way valve 700 is used to prevent the cleaning agent from flowing back into the input section, and can also prevent the liquid material output by the oiling mechanism 100 or the dispensing mechanism 200 from flowing back into the cleaning channel 430.
[0042] like Figures 1-4As shown, in another embodiment of this utility model, the output channel 440 includes a connecting groove 441 and a confluence groove 442. There are two sets of connecting grooves 441, each connected to the oil injection channel 410 and the glue injection channel 420 respectively. The output ends of both sets of connecting grooves 441 are connected to the confluence groove 442. In this embodiment, the output end of the second one-way valve 700 extends into the connecting groove 441. When the cleaning agent enters the connecting groove 441 from the second one-way valve 700, it can clean and eliminate at least a portion of the residue in the connecting groove 441, reducing the risk of mixing.
[0043] like Figure 3 As shown, in another embodiment of this utility model, the cleaning channel 430 is connected to the output channel 440. A second one-way valve 700 is provided at the output end of the cleaning channel 430. The first one-way valve 600 is located in the part of the cleaning channel 430 near the input end of the second one-way valve 700. The liquid material output from the oil injection channel 410 or the glue injection channel 420 passes through the first one-way valve 600 and the second one-way valve 700 in sequence before entering the output channel 440. The cleaning agent output by the cleaning mechanism 300 first passes through the cleaning channel 430 near the first one-way valve 600, and then is output from the second one-way valve 700 into the output channel 440. This effectively ensures that the cleaning agent can remove the residue at the output end of the first one-way valve 600, further reducing the risk of mixing.
[0044] like Figures 1-4 As shown, in another embodiment of this utility model, a MEMS flow sensor 443 is provided on the inner wall of the output end of the confluence groove 442. The MEMS flow sensor 443 is a patch micro-flow sensor. This sensing technology is a mature and established technology, and will not be described in detail in this embodiment. The use of MEMS sensing technology is beneficial to improving the control accuracy of dispensing or oil injection.
[0045] The oil injection mechanism 100 is connected to the external lubricating oil supply system pipeline, the glue dispensing mechanism 200 is connected to the external sealant supply system pipeline, and the cleaning mechanism 300 has two sets of input ends, which are respectively connected to the external oil stain cleaner supply system and the residual glue cleaner supply system pipeline.
[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
