Description

Technical Field

[0001] This application relates to the technical field of automated production equipment for vacuum insulation panels, and more particularly to an automated vacuum insulation panel adhesive applicator. Background Technology

[0002] Vacuum insulation panels are commonly used in refrigerators, water heaters, and other applications requiring heat preservation. They effectively reduce energy consumption, and in some regions, insulation materials, represented by vacuum insulation panels, are considered the "fifth energy source." Depending on the production needs of refrigerators, water heaters, and similar appliances, double-sided adhesive is often applied to one side of the vacuum insulation panel to facilitate subsequent production and improve efficiency.

[0003] Vacuum insulation panels come in a wide variety of specifications and are quite large in size. Currently, the application of double-sided tape is usually done manually, which is time-consuming and labor-intensive, and does not help reduce production costs or improve production efficiency. Commonly used labeling machines on the market are generally only suitable for applying small-sized labels, and are often unsuitable for scenarios where the length, width, and height of vacuum insulation panels vary greatly.

[0004] To reduce the labor costs of applying double-sided tape to vacuum insulation panels, lower production costs, and improve production efficiency, this invention proposes an automated device suitable for applying large-sized double-sided tape to various specifications. Summary of the Invention

[0005] This application primarily optimizes automated equipment suitable for producing vacuum insulation panels of various sizes, enabling the application of large-size double-sided adhesive tape. The technical solution adopted is as follows:

[0006] An automated vacuum insulation panel adhesive applicator includes a feeding area, an adhesive applicator, and a receiving area arranged sequentially along the transport direction; the adhesive applicator includes a material roll rack, a feeding mechanism, an adhesive coating mechanism, and a cutting mechanism.

[0007] The feeding mechanism delivers double-sided adhesive from the material roll rack to the covering mechanism for bonding with the VIP board; the cutting mechanism is located between the covering mechanism and the feeding mechanism and is used to cut the double-sided adhesive.

[0008] The feeding area, adhesive application area and receiving area are all equipped with conveyor belt devices. A limit block is provided on one side of the conveyor belt device in the feeding area. The limit block and the double-sided adhesive, feeding mechanism and VIP plate on the material roll frame are the same positioning reference on one side.

[0009] The adhesive application area is equipped with a position sensor near the coating mechanism to control the transportation operation of the feeding mechanism and the bonding operation of the adhesive coating mechanism.

[0010] A magnetic powder brake is provided at either end of the material roll frame to stop the double-sided adhesive transport.

[0011] Optionally, a buffer mechanism is provided between the material roll holder and the feeding mechanism for pre-tightening the double-sided adhesive;

[0012] The buffer mechanism has vertical translational freedom along the vertical transport direction;

[0013] The feeding mechanism lifts the double-sided tape linkage buffer mechanism upwards, and this lifting action is the input signal for feeding the material roll frame.

[0014] Optionally, an air shaft is provided in the middle section of the roll bar where the double-sided film is placed, and the air shaft restricts the movement of the double-sided film along the axial direction of the roll bar.

[0015] Optionally, the feeding mechanism is provided with a telescopic device at its conveying end along the transport direction; the telescopic device is inclined at a certain angle to the conveyor belt device.

[0016] Optionally, an air blowing pipe is provided at the lower end of the feeding mechanism near its conveying end.

[0017] Optionally, the cutting mechanism includes a cutting process, a cutting process, and a return process.

[0018] Optionally, the cutter of the cutting mechanism is a double-edged blade used for reciprocating cutting.

[0019] Optionally, the covering mechanism includes a roller that rotates circumferentially and a lifting device, wherein the roller acts to press and bond the double-sided adhesive to the VIP board;

[0020] The lifting device drives the roller shaft to have vertical translational freedom along the vertical transport direction.

[0021] Optionally, the roller includes a rotating shaft and a sponge wrapped around the circumference of the rotating shaft.

[0022] Optionally, the adhesive application area is provided with a feed horn at the input end of its conveyor belt device.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. This application's solution utilizes automated equipment to apply double-sided tape to vacuum insulation panels of various sizes, effectively reducing manpower, improving production efficiency, lowering production costs, and ensuring consistency in double-sided tape application. The double-sided tape cylinder and the vacuum insulation panel use the same positioning reference on one side, ensuring application accuracy. Simply changing the tape specification allows it to be applied to various sizes of vacuum insulation panels and similar application scenarios.

[0025] 2. The proposed solution uses a buffer mechanism between the material roll rack and the feeding mechanism to pre-tighten the double-sided tape. This prevents the double-sided tape from sticking to other parts of the equipment and also buffers the tension of the feeding mechanism, preventing the double-sided tape from being pulled too hard due to the large starting inertia, which could cause it to break or be pulled off-center.

[0033] The following is in conjunction with the appendix Figure 1 -6 provides further details regarding this application.

[0034] This application discloses an automated vacuum insulation board adhesive applicator, which includes a feeding area 1, an adhesive applicator 2, and a receiving area 3 arranged sequentially along the transport direction. The adhesive applicator 2 is equipped with automated equipment to perform an automatic double-sided adhesive applicator process for VIP boards 4 (vacuum insulation boards). Two workers are arranged in the feeding area 1 and the receiving area 3 to complete the feeding and receiving of materials.

[0035] The adhesive application area 2 provided in this application includes a material roll holder 21, a feeding mechanism 22, an adhesive application mechanism 23, and a cutting mechanism 24. The process is as follows: the feeding mechanism 22 conveys double-sided adhesive from the material roll holder 21 to the adhesive application mechanism to be bonded to the VIP board 4; the cutting mechanism 24 is placed between the adhesive application mechanism and the feeding mechanism 22 and is used to cut the double-sided adhesive.

[0036] The aforementioned roll holder 21 is used to hold double-sided adhesive rolls 6. The design incorporates an air-expanding shaft 212 in the middle section of the roll rod holding the double-sided adhesive rolls 6 to ensure that the double-sided adhesive rolls 6 do not move axially during operation. Simultaneously, a magnetic powder brake 211 is designed at either end of the roll holder 21 to stop the double-sided adhesive transport, ensuring that excessive double-sided adhesive is not delivered when the equipment pauses application.

[0037] The feeding mechanism 22 is equipped with a telescopic device 221 at its conveying end along the transport direction. The telescopic device 221 is inclined at a certain angle to the conveyor belt device 5. When the VIP board 4 has not reached the adhesive application point, the telescopic device 221 retracts with the double-sided adhesive. When the VIP board 4 reaches the adhesive application point, the telescopic device 221 and the feeding mechanism 22 extend with the double-sided adhesive. At the same time, structurally, an air blowing pipe 222 is provided below the feeding mechanism 22 near its conveying end to blow the double-sided adhesive extending from the head of the telescopic device 221 forward, ensuring good contact between the double-sided adhesive head and the vacuum insulation plate.

[0038] The coating mechanism includes a circumferentially rotating roller 231 and a lifting device 232. The roller 231 is a single section of shaft that wraps around the sponge. When the VIP board 4 moves to the designated position, the lifting device 232 controls the roller 231 to move downward, pressing the double-sided adhesive onto the VIP board 4 to achieve a good double-sided adhesive application effect. At the same time, the double-sided adhesive is squeezed onto the VIP board 4, which applies sufficient tension to the double-sided adhesive cylinder, allowing the equipment to operate normally.

[0039] The cutting mechanism 24 mainly includes three actions: knife feeding, cutting, and knife return. The cutter uses a double-edged blade, which can cut the material in both directions. The cutting mechanism 24 is a device that cuts the double-sided tape after it has been applied to a vacuum heat insulation plate.

[0040] The preferred design of this application is that a buffer mechanism 25 is provided between the material roll rack 21 and the feeding mechanism 22 for pre-tightening the double-sided adhesive. The buffer mechanism causes the double-sided adhesive wrapped around its upper end to form a zigzag transition section. The buffer mechanism 25 has vertical translational freedom along the vertical transport direction. When the equipment stops feeding, it descends by its own weight, which can pull the extra section of double-sided adhesive material fed by the pre-tightening rack due to inertia, thus preventing the double-sided adhesive from sticking to other parts of the equipment and affecting normal operation. When the work starts, the pulling force generated by the feeding mechanism 22 transporting the double-sided adhesive when applying the double-sided adhesive from the rear section will lift the buffer mechanism 25 upward. This lifting action is the input signal for the material roll rack 21 to feed the material, starting the feeding process. This can prevent the double-sided adhesive from being pulled too much due to the large inertia of the rack, which could cause it to break or be pulled off-center.

[0041] The adhesive application area 2 provided in this application includes a central control screen as a human-machine interface. Operators can control the equipment through the central control screen. A position sensor is provided in the adhesive application area 2 near the coating mechanism to control the transportation work of the feeding mechanism 22 and the bonding work of the coating mechanism 23. The central control screen is connected to all the equipment in the adhesive application area 2 to realize the intelligent operation of the equipment.

[0042] The equipment in this application includes a feeding area 1, an adhesive application area 2, and a receiving area 3, all equipped with conveyor belt devices 5. A limiting block 11 is provided on one side of the conveyor belt device 5 in the feeding area 1 to facilitate centering during feeding. A feeding horn 26 is provided at the input end of the conveyor belt device 5 in the adhesive application area 2 to facilitate material guidance and prevent collision and deviation. The preferred design is that the limiting block 11 and the mechanisms of subsequent processes, such as the double-sided adhesive on the material roll holder 21, the feeding mechanism 22, and the feeding horn 26 of the VIP plate 4, are all based on the same reference on the same side, so that the double-sided adhesive and the vacuum insulation plate have a definite positional relationship, ensuring the quality of double-sided adhesive application.

[0043] like Figure 4 The equipment's workflow is as follows:

[0044] VIP board 4 is placed against limit block 11 in feeding area 1. As it moves to adhesive application area 2 via conveyor belt, when the sensor detects that VIP board 4 has reached the designated position, it sends feedback to the central control screen and controls the extension device 221 of feeding mechanism 22 to extend forward to transport double-sided adhesive and release it. The central control screen then controls adhesive application mechanism 23 to descend, pressing the double-sided adhesive and VIP board 4 together. When the sensor detects that the end of VIP board 4 has reached the designated position, it sends feedback to the central control screen to stop the conveyor belt in adhesive application area 2. Feeding mechanism 22 presses the double-sided adhesive together and simultaneously controls cutting mechanism 24 to cut the double-sided adhesive. Then, extension device 221 of feeding mechanism 22 retracts. The central control screen controls magnetic powder brake 211 to brake material roll 21 and stop transporting double-sided adhesive. The conveyor belt in adhesive application area 2 continues to rotate to receiving area 3 for finished product collection.

[0045] The double-sided tape applicator provided in this application is a continuous operation mechanism, which can be operated by two workers. One worker places the VIP board 4 in the feeding area 1, aligning it with the positioning block. The conveyor belt in the feeding area 1 continues to operate, and the VIP board continues to move forward. When the position sensor detects that the VIP board has reached the designated position in the tape application area 2, such as... Figure 5 When the conveyor belt in the adhesive application area 2 stops, the feeding mechanism 22 delivers double-sided adhesive, and the coating mechanism 23 presses down to adhere the double-sided adhesive to the VIP board 4. The conveyor belt continues to run, simultaneously moving the double-sided adhesive. The buffer mechanism 25 experiences a slight lifting motion, which serves as an input signal to control the rotation and feeding of the double-sided adhesive roll. When the tail end of the VIP board 4 reaches the designated position in the adhesive application area 2, the conveyor belt in the adhesive application area 2 stops, the cutting mechanism 24 cuts the double-sided adhesive, and the feeding mechanism 22 retracts it. Figure 6The conveyor belt in the adhesive application area 2 operates, the VIP continues to move forward, and the adhesive application mechanism 23 is raised. At this time, the buffer mechanism 25 falls back under the action of gravity, storing the excess material from the double-sided adhesive roll due to rotational inertia, thus maintaining a certain tension on the double-sided adhesive. Upon reaching the receiving area 3, another worker stacks and collects the VIP boards 4 with the double-sided adhesive applied.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
