Description

Technical Field

[0001] The invention relates to the technical field of headrest processing, and in particular to a headrest rod oiling device. Background Art

[0002] The headrest is an important component of the car seat. When the headrest is installed on the seat back, a uniform and thin layer of silicone oil needs to be applied on the surface of the headrest rod to achieve operational flexibility during installation. If the oil layer is thicker, it will easily contaminate the headrest or the seat surface. If it is too thin, it will cause a large operating force for up and down adjustment after the headrest guide sleeve is unlocked.

[0003] In the prior art, during the oiling process, the headrest rod cannot be stably fixed in the predetermined position, which may cause the oiling position to shift and affect the oiling effect. After oiling, excess lubricating oil remains on the headrest rod, which not only wastes resources but also may affect subsequent processing or use. Headrest rods of different models or sizes require different oiling positions and methods. The prior art lacks a flexible adjustment mechanism and cannot be adjusted according to the specific size and shape of the headrest rod, thereby limiting its scope of application and poor compatibility.

[0034] Specifically, as shown in the figure, the adjustment mechanism includes an insertion block 19 with a socket, a slide groove 18 allowing the insertion block 19 to move laterally is arranged on the top plate of the spray box 4, a positioning component for positioning the insertion block 19 is arranged on the top plate of the spray box 4, and a belt sealing component 24 is arranged at the bottom of the slide groove 18.

[0035] Specifically, as shown in the figure, the slide groove 18 passes through the top plate up and down, the belt sealing assembly 24 includes a shell 25 fixed to the bottom surface of the top plate, a pair of track units are arranged in the shell 25 in the front-to-back direction, the track unit includes track pieces 26 symmetrically arranged on the left and right, and cross rails 27 connected between the track pieces 26, the track pieces 26 and the cross rails 27 form an arch structure, and slide rails 28 are correspondingly arranged on the opposite side of the track pieces 26 of the two track units, and sliders 29 are slidably matched on the slide rails 28 on the left and right sides, and belts 30 are movably placed on the track pieces 26 and the cross rails 27, and the two sides of the belt 30 are fixedly connected to the sliders 29 on both sides, and the belt 30 is provided with a socket allowing the headrest rod 2 to be inserted, the belt 30 is fixedly connected to the insertion block 19, the socket of the belt 30 is opposite to the socket of the insertion block 19 up and down, and the belt 30 movably covers the through hole of the slide groove 18. The positioning assembly includes an adjustment slot 22 transversely arranged on the top plate, and a plurality of adjustment holes 23 are evenly spaced in the transverse direction on the adjustment slot 22. An adjustment plate 20 extends from one side of the insertion block 19 close to the adjustment slot 22. The adjustment plate 20 is located directly above the adjustment slot 22, and a fixing pin 21 cooperating with the adjustment hole 23 is vertically arranged on the adjustment plate 20.

[0036] Lateral movement of insert block 19:

[0037] The insert block 19 is provided with an insert hole for connecting with the second insert position 6 (or a related fixing member), thereby driving the second insert position 6 to move.

[0038] A slide groove 18 is provided on the top plate of the spray box 4, and the slide groove 18 allows the insertion block 19 to move laterally (ie, in the left and right directions) inside the slide groove 18.

[0039] Movement Mechanism:

[0040] The insertion block 19 cooperates with the positioning components (such as the adjustment plate 20 and the fixing pin 21). By adjusting the position of the fixing pin 21 in the adjustment slot 22 and the adjustment hole 23, the insertion block 19 can be accurately positioned and fixed in the slide slot 18.

[0041] When the relative distance between the first insertion position 5 and the second insertion position 6 needs to be adjusted, the operator can loosen the fixing pin 21 , manually push the insertion block 19 in the slide slot 18 to move to a desired position, and then re-fix the fixing pin 21 to lock the insertion block 19 .

[0042] Belt Seal Assembly 24 Sealing Mechanism:

[0043] The belt 30 is provided with a socket which is opposite to the socket of the insertion block 19, so as to allow the headrest rod 2 to be inserted. At the same time, the belt 30 movably covers the through hole of the slide slot 18 to form a sealing barrier.

[0044] When the insert block 19 moves in the slide groove 18 , the belt 30 moves therewith and always keeps covering the through hole of the slide groove 18 , thereby preventing the oil mist, lubricating oil, etc. inside the spray box 4 from leaking into the external environment through the slide groove 18 .

[0045] This sealing mechanism helps to keep the interior of the spray box 4 clean and dry, reducing environmental pollution and safety hazards.

[0046] Specifically, as shown in the figure, a half-insertion block 13 is fixedly provided on the first insertion position 5, and the clamping mechanism 8 includes a rodless cylinder 14 fixed in the spray box 4 along the front-to-back direction, and the rodless cylinder 14 drives the telescopic rod 15 to move forward and backward. The outer end of the telescopic rod 15 is fixedly connected with a pressure plate 16, and a pressure block 17 is provided on the side of the pressure plate 16 close to the first insertion position 5. After the pressure block 17 is driven, the headrest rod 2 is pressed and fixed in the first insertion position 5.

[0047] Specifically, as shown in the figure, the blowing mechanism 12 includes a lifting cylinder 31 vertically arranged in the spray box 4, and the air rod end of the lifting cylinder 31 is horizontally fixed with a lifting plate 32. Two groups of blowing components are arranged on the lifting plate 32 corresponding to the two headrest rods 2, and each group of blowing components includes a pair of blowing guns 33. The two blowing guns 33 are respectively arranged on the left and right sides of the headrest rod 2, and the air nozzles 34 of the two blowing guns 33 are relatively facing the headrest rod 2.

[0048] Working principle of the blowing mechanism 12

[0049] Working process:

[0050] When the headrest rod 2 completes the oil injection operation, the lifting cylinder 31 is started. According to the preset program or the instruction of the operator, the gas rod of the lifting cylinder 31 drives the lifting plate 32 to move up and down to a suitable position.

[0051] When the air blowing gun 33 on the lifting plate 32 is aimed at the headrest rod 2, the air blowing gun 33 starts to work and blows air to the surface of the headrest rod 2. The function of the air flow is to blow away the excess lubricating oil on the headrest rod to avoid the problem caused by excessive lubricating oil residue.

[0052] During the blowing process, parameters such as the airflow intensity, blowing time and blowing angle of the blowing gun 33 can be adjusted as needed to ensure that the blowing effect is optimal.

[0053] Specifically, as shown in the figure, the oil injection mechanism 10 includes a pair of spray guns 10, which are mounted on the machine base 3 through support rods. Spray holes 9 are opened on the rear side of the spray box 4 corresponding to the positions of the two headrest rods 2. The nozzles of the spray guns 10 extend into the spray holes 9, and the spraying direction of the spray guns 10 is adjustable.

[0054] Working process:

[0055] After the headrest rod 2 is inserted into the insertion position of the spray box 4 and fixed, the oil spraying mechanism 10 starts to work. The spray gun sprays an appropriate amount of lubricating oil from the spray hole 9, which directly acts on the surface of the headrest rod 2.

[0056] Parameters such as the amount, speed and direction of the oil spray can be adjusted according to the preset program or the operator's instructions to ensure that the lubricating oil can cover the surface of the headrest rod evenly and in an appropriate amount.

[0057] During the oil spraying process, the operator can observe the oil spraying effect through the visual window on the side of the spray box 4 and make real-time adjustments as needed.

[0058] Specifically, as shown in the figure, the spray box 4 is provided with a sensor 7 for sensing whether the headrest rod is inserted into the first insertion position 5 and the second insertion position 6.

[0059] Specifically, as shown in the figure, a control box 37 , a waste oil collection box 35 , and a pressure barrel 36 are disposed in the base 3 .

[0060] Specifically, the specific implementation principle of the present invention is:

[0061] Insertion of the headrest rod: vertically insert the two headrest rods 2 into the first insertion position 5 and the second insertion position 6 on the spray box 4 respectively.

[0062] Insertion position adjustment: According to the specific size or oiling requirements of the headrest rod 2, the position of the second insertion position 6 is adjusted through the adjustment mechanism, thereby adjusting the relative distance between the first insertion position 5 and the second insertion position 6. Therefore, the present invention can adapt to headrests of different models and specifications, increasing the compatibility of use.

[0063] Pressing the headrest rod: When the headrest rod 2 is located at the first insertion position 5, the pressing mechanism 8 is activated. The rodless cylinder 14 drives the telescopic rod 15 to move forward, thereby driving the pressing plate 16 and the pressing block 17 to press the headrest rod 2. In this way, the headrest rod can remain stable during the oiling process to prevent the oiling effect from being affected by movement or shaking.

[0064] Oil spraying operation: The oil spraying mechanism 10 starts working. The mechanism usually includes one or more pairs of spray guns 10, which are mounted on the machine base 3 or the rear side of the spray box 4 through a support rod. The nozzle of the spray gun extends into the corresponding spray hole 9 in the spray box 4 and sprays oil at the headrest rod 2. Parameters such as the oil spraying amount, oil spraying speed and oil spraying direction can be adjusted as needed to ensure that the oil coating is uniform and meets the quality requirements.

[0065] Blowing off excess oil: After the oiling is completed, the blowing mechanism 12 is activated. The mechanism usually includes one or more blowing guns 33, which are arranged in the spray box 4 and correspond to the position of the headrest rod 2. The blowing gun blows out air to blow away excess lubricating oil on the headrest rod 2. This helps to reduce the waste of lubricating oil and ensure that the surface of the headrest rod is clean and free of oil stains.

[0066] Observe the oiling effect: During the oiling process, the operator can observe the oiling effect through the visual window 11 on the side of the spray box 4. If uneven oiling or other problems are found, the relevant parameters of the oil spraying mechanism, the air blowing mechanism or the pressing mechanism can be adjusted in time.

[0067] Automatic control: The entire oiling process can be automatically controlled by the control system. The control system can automatically adjust the working state of each mechanism according to the preset program and parameters to ensure the accuracy and efficiency of the oiling process. At the same time, the control system can also receive signals from sensors such as the sensor 7, monitor the insertion state of the headrest rod and the oiling effect in real time, and respond accordingly.

[0068] The present invention realizes rapid and accurate oiling of the headrest rod by mechanization and automation. Compared with manual oiling, it greatly improves work efficiency and reduces the tediousness and time-consuming manual operation. The oil injection mechanism can accurately control the amount, speed and direction of oil injection to ensure that the lubricating oil can be evenly and appropriately covered on the surface of the headrest rod, avoiding the problem of uneven or excessive oiling that may occur during manual oiling.

[0069] The spray box is provided with an adjustment mechanism, which can flexibly adjust the position of the second insertion position to adapt to headrest rods of different specifications and sizes. This design improves the versatility and adaptability of the device and reduces the dependence on a specific headrest rod.

[0070] The clamping mechanism can firmly fix the headrest rod to prevent it from moving or shaking during the oiling process. This helps to ensure the stability of the oiling process and the reliability of the oiling quality.

[0071] The air blowing mechanism can blow away the excess lubricating oil on the headrest rod in time, reducing the waste of lubricating oil and environmental pollution. The air blowing mechanism blows away and collects the excess lubricating oil, which helps to keep the working environment clean and tidy. This helps to improve work efficiency and the working comfort of employees.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0073] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
