First embodiment

The present embodiments provide an apparatus for applying a liquid to an inner wall of a workpiece. Wherein the workpiece may be a cap of a lipstick, and the liquid may be a lubricant.

As shown in fig. 1-5, embodiments of the present invention provide an apparatus for applying a liquid to an inner wall of a workpiece. The device comprises a workpiece seat 11, a coating rod 21, a coating rod fixing seat 22, a liquid storage ring 23, a liquid storage bottom plate 24, a dropper 25, a liquid conveying pipeline 26, a first driving part 31 and a second driving part 212. Wherein the content of the first and second substances,

the workpiece seat 11 is used for fixing a workpiece 100, and the workpiece can be a tube cap of lipstick.

The coating rod 21 is used for dipping liquid from the liquid storage ring 23 and then extending into the inner cavity of the workpiece 100 to coat the inner wall of the workpiece with the liquid. The coating rod 21 is provided below the workpiece holder 11 and extends into the workpiece 100 by moving from bottom to top. The coating rod 21 includes a body including an airtight chamber (not shown in the drawings) and a piston (not shown in the drawings) disposed in the airtight chamber, and a coating elastic membrane 211. The coating elastic film 211 is coated on the upper part of the airtight cavity, and the coating elastic film 211 is expanded outwards or contracted inwards through the reciprocating motion of the piston in the airtight cavity. The coating rod 21 is capable of reciprocating between a first position and a second position. In the first position, the coating elastic membrane 211 of the coating rod 21 is aligned in height with the reservoir ring 23. In the second position, the coating elastic film 211 of the coating rod 21 is aligned in height with the portion of the inner wall of the workpiece to be coated. By applying the elastic film 211 with the liquid dipped and then applied to the inner wall of the work, not only can the dosage be accurate, but also a very small amount of liquid, for example, less than 1 mg of liquid, can be applied.

The coating rod fixing seat 22 is used for fixing a plurality of coating rods 21, so that the coating rods 21 can move together.

The liquid storage ring 23 is used for storing a certain amount of liquid and is dipped on the coating rod 21. The coating rod 21 dips the liquid from the liquid storage ring 23 through the coating elastic film 211, and the inner hole diameter of the liquid storage ring 23 is at least equal to the outer diameter of the coating elastic film 211 which bulges outward. The axes of the applicator rod 21, the reservoir ring 23 and the interior cavity of the workpiece 100 coincide. Thus, the coating rod 21 can dip the liquid from the reservoir ring 23 and coat the workpiece 100 with the liquid by moving up and down linearly.

The liquid storage bottom plate 24 is used for accommodating the liquid storage ring 23, the upper end of the liquid storage bottom plate 24 is fixed on the workpiece seat 11, and the lower end of the liquid storage bottom plate is connected with the coating rod 21. The liquid storage bottom plate 24 is provided with a containing groove 241 for containing the liquid storage ring 23, and the containing groove 241 is provided with a longitudinal hole 242 and a transverse hole 243. The coating rod 21 passes through the longitudinal hole 242 of the container 241, and the feeding tube 26 passes through the lateral hole 243 of the container 241 to be connected to the reservoir ring.

The dropper 25 is used for receiving liquid delivered by a pump (not shown in the figure) and dropping the liquid into the infusion tube 26. The dropper 25 is connected with the pump and arranged on two sides of the liquid storage ring 23;

the infusion pipe 26 is used for receiving the liquid dripped by the dropper 25 and delivering the liquid to the liquid storage ring 23. The inlet of the transfusion pipe 26 is positioned below the outlet of the dropper 25, and the outlet is connected with the liquid storage ring 23. The infusion tube 26 is fixed to the work piece holder 11.

The first driving part 31 is used for driving the coating rod 21 to move up and down. Namely, the coating rod 21 is driven by the first driving part 31 to extend into the inner cavity of the workpiece 100 or to withdraw from the inner cavity of the workpiece 100. The first driving part 31 is located below the coating rod 21.

The second driving part 212 is used for driving the movement of the piston in the airtight cavity of the coating rod 21. That is, by driving the movement of the piston, the pressure in the airtight chamber of the coating rod 21 is changed, thereby affecting the degree to which the coating elastic film 211 bulges outward. Fig. 6 and 7 are schematic views showing that the coating elastic film 211 of the coating rod 21 is not bulged outward and is bulged outward.

In a specific implementation, if the workpiece is a lipstick cap, the fluid described in this embodiment may be a lubricating oil.

In this embodiment, the elastic coating film 211 covers the upper portion of the airtight chamber, i.e., not the entire airtight chamber. Thus, a gas-tight chamber, and even a whole coating rod, with better strength is preferred.

The liquid feeding tube 26 of the present embodiment is preferable to allow the liquid storing ring 23 to have a sufficient time to store the liquid. It will be understood that it is also possible that the dropper 25 sprays directly onto the accumulation ring 23.

In this embodiment, the liquid storage ring 23 is a felt ring. Specifically, the felt ring of this embodiment is the wool felt, and the wool felt is elastic, and the texture is tough, wear-resisting, levels, difficult loose, advantage such as indeformable when meeting oil, wide application in occasions such as sealed, oil absorption, thermal-insulated. Is a preferred form of reservoir ring 23, particularly where the liquid is lubricating oil. It will be appreciated that other materials for the liquid to be absorbed are possible.

The coating rod fixing seat 22 of the present embodiment can drive a plurality of coating rods 21 to move at the same time, and the efficiency is higher, which is a preferable mode.

In this embodiment, the device further comprises a base plate 12 and a guide post 13. The lower end of the guide post 13 is fixed to the bottom plate 12, and the upper end of the guide post 13 passes through the coating rod fixing seat 22 and is fixed to the workpiece seat 11. The coating rod fixing seat 22 is provided with a through hole matched with the guide post 13, and the coating rod fixing seat 22 moves up and down along the guide post 13. Thus, the up-and-down movement track of the coating rod fixing seat 22 is more accurate and stable, and the coating liquid is more accurate, which is the preferable mode.

The reservoir bottom plate 24 of this embodiment can stabilize the position of the reservoir ring 23, and facilitate the accurate insertion of the coating rod 21 into the reservoir ring 23. The elastic coating film 211 of the coating rod 21 is preferably attached to the inner wall of the liquid storage ring 23 so that the coating rod 21 can obtain a proper amount of liquid.

In this embodiment, it is preferable that the coating rod fixing base 22 and the piston in the airtight chamber are driven by two driving members, i.e., the first driving member 31 and the second driving member 212. Thus, the structure is simple and the control is easier.

In this embodiment, the first driving member 31 and the second driving member are both air cylinders. The use of the air cylinder makes it possible to simplify the structure of the entire apparatus and reduce the cost, which is a preferable mode. In addition, the amount of the liquid dipped by the coating bar 21 and the amount of the liquid applied by the coating bar 21 to the inner wall of the work 100 are related to the degree of outward bulging of the coating elastic film 211. It is therefore necessary to precisely control the degree to which the coated elastic film 211 bulges outward. And the piston is driven by the cylinder, so that relatively accurate control can be realized under the condition of simple structure.

In this embodiment, the pump is a pneumatic injection valve. The pneumatic injection valve is used, so that the cost can be reduced on the premise of ensuring the accuracy of the injection amount, and the pneumatic injection valve is an optimal mode.

In this embodiment, the liquid is dropped to the liquid feeding tube 26 by the dropping tube 25, so that the liquid in the liquid feeding tube 26 is enough every time the liquid storage ring 23 stores the liquid, which is a preferable mode. If the pump and the infusion line are directly connected by tubing, there may be a problem of insufficient liquid in the infusion line 26 due to the easy backflow due to the long tubing.

In this embodiment, the fixed end of the first driving member 31 is fixed to the base plate 12, and the driving end is connected to the coating rod fixing seat 22. The base plate 12 further includes a clamping block 311 for clamping the first driving member 31 from the side and a push rod 312 for pushing the clamping block 311, wherein the push rod 312 is located on one side of the clamping block 311 in the horizontal direction. The push rod 312 includes a fixed end fixed on the bottom plate 12 and a push-pull end for pushing the clamping block 311 tightly. The push rod 312 can horizontally rotate the push-pull end with the fixed end as a fulcrum to abut against or leave the clamping block 311. In this way, it is preferable to mount and fix the first driving member 31 more conveniently and accurately, and also to facilitate the detachment.

Specifically, the step of clamping the first drive component is: after the first driving part 31 and the coating rod holder 22 are connected, the clamping blocks 311 are placed on both sides of the fixing portion of the first driving part 31, i.e., both sides of the cylinder. Then the push-pull end of the push rod 312 is pushed to make the clamping block 311 tightly abut against the cylinder. The clamping block 311 is then fixed to the base plate 12 by means of bolts and nuts. Finally, a fixing block (not shown in the figures) above the push rod 312 is also fixed on the bottom plate 12 through bolts and nuts.

In this embodiment, the apparatus further comprises a sensor 41 for monitoring whether the workpiece 100 is loaded on the workpiece holder.

In addition, in order to control the operation of the first 31 and second 212 driving members, the device is provided with a unified control mechanism (not shown in the figures). The control mechanism is electrically connected with the first driving part 31, the second driving part 212, the sensor 41, the pump and the like.

Second embodiment

To further understand the features and technical contents of the embodiments of the present invention, the working procedure of the apparatus for applying liquid to the inner wall of the workpiece, i.e., the method for applying liquid to the inner wall of the workpiece according to the embodiments of the present invention, will be described below. The method is performed by a control mechanism of the device. The workpiece is a lipstick tube cap, and the liquid is lubricating oil. The method comprises the following steps:

step 501: information that the workpiece has been loaded is acquired. When the workpiece is placed on the workpiece seat 11, the sensor 41 of the workpiece seat 11 is triggered and the control mechanism is notified. And after the control mechanism acquires the sensor information, the next step is carried out. The workpiece 100 here is a lipstick cap.

Step 502: and absorbing and storing the liquid. The liquid is delivered to the dropper 25 by a pump, is dropped into the infusion tube 26 by the dropper 25, and is delivered to the liquid storage ring 23, i.e., the felt ring, which absorbs the liquid by capillary action and accumulates in the felt ring, by the infusion tube 26.

Step 503: dipping the liquid. The second driving part 212 is controlled to move, the pressure in the airtight cavity of the coating rod 21 is increased, the coating elastic membrane 211 is enabled to bulge outwards to the first outer diameter, the outer wall of the coating elastic membrane 211 is enabled to abut against the inner wall of the liquid storage ring 23, and the purpose of dipping liquid is achieved. The first outer diameter is set according to the amount of liquid to be dipped and is achieved by setting the displacement of the second driving member 212. After the coated elastic film 211 is swollen for a predetermined time, the second driving part 212 is reset and the coated elastic film 211 is retracted. The preset time here is to ensure adequate dipping.

Step 504: a coating liquid. The first driving part 31 is controlled to move, so that the coating rod 21 is pushed to move upwards, and the coating rod 21 extends into the tube cap of the lipstick. And the coating elastic film 211 on the outside of the coating rod 21 is aligned with the portion of the workpiece to be coated, i.e., the recessed ring of the cap of the lipstick. Then the first driving part 31 is controlled to move again, so that the coating elastic film 211 is bulged outwards to a second outer diameter, and the outer wall of the coating elastic film 211 abuts against the concave ring of the tube cap of the lipstick, thereby achieving the purpose of coating liquid. Similarly, the second outer diameter is set according to the amount of the liquid to be coated, and is achieved by setting the displacement amount of the second driving member 212. After the coating elastic film 211 is swollen for a predetermined time, the second driving part 212 is reset, and the coating elastic film 211 is retracted, thereby completing the process of coating the liquid. Also, the predetermined time is herein to ensure sufficient coating of the liquid.

Step 505: and resetting. The first driving part 31 is controlled to reset, and the coating rod 21 is driven to reset downwards to the original position.

Step 501 and step 505 are repeated until all workpieces of the batch have been coated with liquid.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
