[0039] Example 1 Meniscus coating equipment and its operation process

[0040] The three-dimensional structure of the meniscus gluing equipment of the present invention is as follows figure 1 As shown, the front view is as figure 2 As shown, the top view is as image 3 As shown, it can be understood from the figure that the main components of the meniscus coating equipment of the present invention, Figure 4 It is a schematic diagram of the operation of the meniscus coating equipment, from which the coating operation process of the meniscus coating equipment of the present invention can be clearly understood.

[0041] The above-mentioned meniscus coating equipment includes a central control panel (1), a PCL control cabinet (2), a film element positioning and loading table (3), a linear motor drive rail (4), and a film element suction mechanical arm (5). ), glue supply device (6), film-coating element flipping and unloading table (7), film-coating element flipping transition frame (8), film-coating element placement rack (9), equipment support table (10), equipment support (11) Equipment dust cover (12); the glue supply device (6) includes glue supply container (6-1), glue spray device (6-2), low-position glue storage container (6-3), liquid delivery The device (6-4), the lifting device (6-5); the film-coating element flipping and unloading stage (7) includes the film-loading stage fixing part (7-1) and the film-absorbing element suction manipulator (7-2).

[0042] Among them, the film element positioning and loading table, the linear motor drive guide rail, the film element suction mechanical arm, the glue spray device, the film element turning manipulator, the film element turning transition frame, the film element lower piece placement frame are fixed on the equipment support table The top is arranged in the order of walking of the coating elements during production. The central control panel is installed and fixed above the front of the dust cover of the equipment, and the components can be adjusted and adjusted without affecting the production process. The PCL control cabinet is installed under the support table, which does not affect the production operation and is beautiful and reasonable. The support table is located on the equipment support, and the firm and shockproof equipment support is reasonable and comfortable in human operation. The glue supply device is independent of the overall equipment, which is easy to clean and use (if the type of glue is changed or production is stopped for maintenance).

[0043] The operation of this meniscus coating equipment completes a coating process through the following process:

[0044] The meniscus coating equipment is fixedly placed and adjusted to a level, and the glue supply device is placed in a reasonable position and leveled. Power on the meniscus coating equipment and the glue supply device, and check whether there are abnormal parts that are not energized, everything is normal, and prepare for coating.

[0045] Open the glue supply device and the liquid delivery pump connected to it, pump the glue in the low-position glue storage container of the glue supply device into the adjustable glue supply container, and at the same time, the glue in the adjustable glue supply container flows through the glue supply pipe In the glue spraying device, a certain height of meniscus coating liquid surface is formed through the nozzle slit in the glue spraying device. In the glue supply device, the excess liquid in the glue supply container flows back to the low glue storage container through the glue overflow area in the glue supply container, and the excess glue in the glue spray device flows back to the low glue storage container through the recovery pipe The container forms a circulating glue supply system.

[0046] The height of the glue supply container can be adjusted by a guide motor at any time, and the liquid level of the meniscus coating film formed in the glue spraying device is observed until the coating film requirement is reached.

[0047] After the coating element reaches the positioning and loading stage of the coating element, it moves forward to the set position with the movement of the conveying roller and completes positioning and starts automatic leveling. After leveling is finished, wait for the next instruction. When the positioning and leveling of the film element to be coated is completed, the suction mechanical arm of the film element starts to move along the linear motor drive rail to a set position above the film element to be coated. The coating element suction mechanical arm starts to move downwards until it touches the surface of the film element to be coated, and the vacuum pump is connected to the coating element suction mechanical arm to start working. The suction cup at the front end of the mechanical arm and the surface of the element to be coated A certain vacuum environment is formed in between, so that the coating film element suction mechanical arm can be fixed and sucked to the coating film element. The coating element suction mechanical arm is equipped with a drainage elastic clip behind its suction cup (relative to the coating film movement direction of the coating element). The clamping member has a grooved metal part, and the coating element suction mechanical arm When the suction cup comes into contact with the coating element, it is in contact with the end of the coating element. After this part comes into contact with the coating element, it can effectively prevent the backflow of residual glue at the end of the coating element during the coating process (commonly known as flapping).

[0048] The film-coating element suction mechanical arm drives the film-coating element to move forward at a certain speed until the front end of the film-coating element and the spray block of the glue spraying device are at a set distance, and the speed reaches the coating film speed close to the forward Move and start coating until the end of the coating element passes through the glue spray block of the glue spray device to complete the coating.

[0049] After the coating is completed, the coating film element sucking mechanical arm continues to move to it, and moves the coating film product to the top of the coating film element inversion transition frame, and places the coating film element on the coating film element inversion transition frame, So far, the film coating element sucks the mechanical arm to complete a film coating process, and then moves to the top of the film coating element positioning and loading table to start a new round of stroke.

[0050] After the coating film product is placed on the coating film element inversion transition rack, the coating film element inversion manipulator moves along the linear motor drive rail to above the coating element. After the coating film element turning manipulator moves above the coating film element, the suction cup at the front end of the coating film element turning manipulator starts to move downward until it contacts the surface of the coating film element. After the suction cup at the front end of the coating element turning manipulator contacts the surface of the coating element, the vacuum pump is connected to the coating element turning manipulator to start working, and a certain vacuum environment is formed between the suction cup and the surface of the coating product, so that the coating The film element is fixed on the coating element turning manipulator. After fixing the coating film element to the coating film element turning manipulator, the coating film element turning manipulator takes the coating film element and moves upward at the same time to reach the set height, and then turns the coating film element 180°, so that the coating film element is coated The membrane side is facing up. After the coating element is turned over 180°, the coating element turning manipulator moves the coating product to the bottom sheet placement rack of the coating element, so that the unloading process of the coating product is completed, and a single-sided single-layer coating product is obtained. If you are going to coat a single-sided multilayer or double-sided heterogeneous product film, you only need to add the continuous glue supply device and the glue spraying device to achieve this, and the coating element turning manipulator moves again to the coating element turning transition transition A new round of unloading process begins at the top of the shelf.

[0051] The film element to be coated starts from the positioning and loading table of the film element, is driven by the film element suction mechanical arm, passes through the glue spray device to complete the film coating process, and obtains the film product, and then places it on the film After the element is turned over on the transition rack, the film-coating element suction manipulator returns to the starting position to prepare the next piece of film-coated element to be grabbed; at the same time, the film-coating element turning manipulator moves to the top of the coating product, After the coating film element turning manipulator sucks and turns the coating film product by 180°, it is placed on the bottom sheet placement table of the coating film element, the production of a product is completed, and the coating film element turning manipulator moves again to the starting position, ready The next piece of the next product is flipped.

[0052] Such one-by-one production of coated elements realizes the high-quality and high-efficiency continuous production of single-sided multilayer or single-layer or double-sided heterogeneous films by wet chemical methods, filling the gap in the continuous production of high-quality and efficient chemical methods. .

[0053] Example 2 The coating film element suction mechanical arm with anti-flailing effect

[0054] The three-dimensional schematic diagram, the front schematic diagram and the top view of the coating film element suction mechanical arm with anti-flipping effect of the present invention are as follows: Figure 5-7 As shown, it mainly includes the following important components: film-coated element walking robot arm (5-2), drainage elastic clip (5-2-2), suction cup (5-2-1).

[0055] Such as Image 6 As shown, the contact part of the end drainage elastic clip (5-2-2) of the coating element (5-2-2) and the coating element (13) has a concave structure, and only the bottom edge overlaps the coating surface of the coating element. The upper surface does not touch any parts, so the residual liquid at the end of the coating film surface of the coating element will not flow back to the upper surface of the coating element to affect the coating effect and quality. The drainage elastic clip (5-2-2) is connected and fixed above the suction cup (5-2-1) through a movable telescopic rod, and the suction cup (5-2-1) is fixed on the coating The film element travel mechanical arm (5-2), so when the film element travel mechanical arm (5-2) moves forward with the motor, the film element suction cup (5-2-1) and drainage elastic The clamping piece (5-2-2) also moves forward at the same time, thereby driving the coating element to move forward to complete the coating. The residual liquid at the end of the coating element simultaneously flows backward along the drainage elastic clip (5-2-2), preventing the residual liquid from returning to the coating surface due to surface tension.

[0056] When the coating element reaches the fixed position and leveling at the upper position of the meniscus coating equipment, the coating element walking mechanical arm (5-2) moves to directly above the coating element to drive the drainage elastic clip ( 5-2-2) Slowly move to the end of the coating element until the contact is completed, and then use the coating element suction cup (5-2-1) to suck and fix the coating element on the suction cup, and then The coating element walking robot arm (5-2) drives the coating element to move forward and reaches the coating area. The coating liquid will remain at the end of the coating element due to surface tension, and the residual coating liquid will be caused by surface tension. It will flow back to the inside. The method of the present invention is fixedly in contact with the drainage elastic clip (5-2-2) at the end of the coating element, so the residual coating liquid of the coating element will flow along the drainage elastic clip. The bottom edge continues to flow, so that no backflow phenomenon occurs at the end of the coating element, which effectively prevents the residual coating liquid at the end of the coating element from affecting the quality of the coating film. By adjusting the height of the drainage elastic clip (5-2-2), the coating film of different thicknesses can be satisfied. At the same time, adjusting the stretch rod of the drainage elastic clip (5-2-2) can meet the requirements of coating the film elements of different lengths. membrane.

[0057] Example 3 Glue spraying device with leveling function [HJ1]

[0058] The structure of the glue spraying device with leveling effect of the meniscus glue coating equipment of the present invention is as follows Figure 8 Shown.

[0059] The leveling device (6-2-5) includes an adjusting wheel (6-2-5-1), a leveling piece (6-2-5-2) and a supporting base (6-2-5-3). The connection between the various components of the leveling device and the glue spraying device can be clearly shown. In addition to the main leveling function, the leveling device is also the main support member for fixing the glue spraying device. The glue device is fixed on the equipment support plate by means of the leveling member support seat and the leveling member shaft support seat. The leveling member mainly relies on the relative movement between the leveling wheel and the leveling member to achieve the leveling of the glue spraying device.

[0060] The glue spraying device is fixedly installed through the supporting base of the leveling member and the supporting base of the rotating shaft of the leveling member to ensure that the glue spraying device is level in the walking direction of the coating element, so that the level in this direction is not affected by other levels. The impact of components. By adjusting and rotating the leveling wheel of the leveling component to move on the metal leveling part with a slope, the glue spraying device can be rotated with the rotating shaft of the leveling part as the central axis, and the glue spraying can be obtained by an auxiliary tool The horizontal deviation of the device will stop rotating until it reaches the expected value and the horizontal error range, and the leveling ends, simple and fast.
