Description

Technical Field

[0001] This utility model relates to the field of automation control technology, and in particular to an automatic bonding device and bonding method for round-bottomed fabrics. Background Technology

[0002] In the current production process of dust collector filter bags, the production of the bag bottom is a crucial step, as it directly affects the sewing strength and sealing performance of the filter bag. The traditional process involves sewing double-layer circular fabric at the bag bottom to ensure structural stability and reliable sealing. However, this process suffers from significant efficiency bottlenecks and labor intensity issues.

[0003] Specifically, the traditional method requires workers to manually align two layers of circular fabric and pre-fix them with double-sided tape. This process is not only time-consuming and labor-intensive, but also requires a large amount of manual work, including simple but repetitive tasks such as tearing off the double-sided tape, pasting, and aligning the fabric. This labor-intensive production method not only reduces production efficiency but also increases the labor intensity of workers, which is detrimental to long-term production stability and cost control.

[0004] To address this challenge, it is crucial to design a device capable of automating or at least semi-automating the alignment and pre-fixation of double-layer circular fabrics. This device needs to efficiently process the fabric, minimizing manual intervention, while ensuring accurate alignment and secure pre-fixation, thus laying a solid foundation for subsequent sewing.

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0042] like Figures 1 to 3 As shown, this utility model embodiment provides an automatic bonding device for round-bottomed fabric. The device includes a base 1, a first positioning component 2, a second positioning component 3, a track component 4, an infrared component 7, a gripping component 7, an adhesive application component 6, and a PLC unit. The PLC unit is electrically connected to the infrared component 7, the first positioning component 2, the second positioning component 3, the track component 4, the infrared component 7, the gripping component 7, and the adhesive application component 6.

[0043] The track assembly 4 is installed on the base 1. The first positioning assembly 2 and the second positioning assembly 3 are installed on the base 1 at designated positions and are used to store circular fabrics. The installation position of the track assembly 4 is adapted to the installation positions of the first positioning assembly 2 and the second positioning assembly 3. The gripping assembly 7 is used to grip the fabric from the first positioning assembly 2 and press it against the fabric in the second positioning assembly 3. Under the action of double-sided adhesive, the two circular fabrics are glued together. The glued fabric is then gripped again from the second positioning assembly 3 and placed in the collection trough 8.

[0044] In this invention, the travel distances of the working ends of the gripping component 7 and the adhesive application component 6 are controlled based on measurement data. The PLC unit presets the travel distance of the track component 4, and simultaneously controls the height of the circular fabric stored in the first positioning component 2 and the second positioning component 3. That is, the above solution adopts an automated approach, effectively achieving the bonding of circular fabric. At the same time, it introduces an intelligent solution, enabling the equipment to be started and stopped immediately, and allowing for modifications to the traditional execution process, thus making the automation solution more complete.

[0045] In some implementations, a sensor (not shown in the figure) may also be included. The sensor is connected to the gripping component 7 and is used to measure the quality data of the fabric gripped by the gripping component. The PLC unit embeds a neural network model, obtains a dataset of quality data components based on the sensor, trains the neural network model, and outputs the trained neural network model so that the quality data corresponds to the executed steps. Based on the quality data obtained by the sensor, the corresponding execution signal is output. The PLC unit performs the corresponding operation based on the execution signal. If the quality data is always 0, it means that the gripping has failed. If the quality data is always the quality data of one piece of fabric, it means that the bonding is unsuccessful and needs to be re-bonded or the fault needs to be troubleshooted.

[0046] The gripping component 7 is mounted on the lifting frame 5. The lifting frame 5 of the track assembly 4 moves horizontally, while the gripping component 7 grips downwards. The infrared component 7 measures the distance from the gripper to the fabric surface and sends this distance to the PLC unit. The PLC unit controls the descent distance of the start-up suction cup and the descent height of the adhesive applicator 6. The infrared component 7, mounted on the lifting frame 5, emits infrared light downwards. The adhesive applicator 6, mounted on the lifting frame 5, is used to press double-sided adhesive onto the bonding area of ​​the fabric.

[0047] In this utility model, the specific structure of the first positioning component 2 includes a first mounting base, a first cylinder 22, and a first limiting post 21, wherein...

[0048] The first mounting bracket is installed on the base 1.

[0049] The first cylinder 22 is electrically connected to the PLC unit, and its control end is mounted on a support plate. Three first limit posts 21 are set and installed on the first mounting base. The first cylinder 22 is vertically installed on the first mounting base and located in the triangular area formed by the first limit posts 21. Through the movement of the control end of the first cylinder 22 and its combination with the first limit posts 21, an adjustable storage area is formed.

[0050] In actual use, as the fabric within the positioning component 7 is gradually removed, the height of the fabric accumulation decreases, requiring the suction cup to descend a longer distance and increasing the gripping time. Therefore, by adjusting the storage height of the aforementioned receiving area, this time can be effectively saved, and the process can be replaced by the first cylinder 22.

[0051] The second positioning component 3 is structurally similar to the first positioning component 2, including a second mounting base, a second cylinder 32, and a second limiting post 31. The second cylinder 32 is electrically connected to the PLC unit. Three second limiting posts 31 are provided and installed on the second mounting base. Unlike the first positioning component 2, the bonding stage in this utility model is planned to be completed within the second positioning component 3, including the stage of applying double-sided adhesive to the fabric, and the stage of bonding another piece of fabric to the first piece of fabric through double-sided adhesive. In the double-sided adhesive application stage, compared to the traditional direct-pressure adhesive, this invention presses the double-sided adhesive against the fabric surface and applies flat pressure, resulting in a tighter bonding surface and significantly reducing gaps. Therefore, a steering mechanism 34 is installed at the control end of the third cylinder 71, and a fork structure 33 is installed at the control end of the steering mechanism 34. The third cylinder 71 controls the fork tips to press against the circular fabric in a preset sequence. The control time is set so that when the flat pressure part 651 at the bottom of the stop block 65 presses the double-sided adhesive against the fabric inside the second positioning component 3, the steering mechanism 34 is controlled to turn, and the third cylinder 71 controls the fork tips to descend and press against the fabric inside the second positioning component 3. The fork tips press against the fabric surface, forming a flat bonding area. Subsequently, the flat pressure part 651 presses the double-sided adhesive against the fabric, and the double-sided adhesive applies flat pressure along one end of the bonding area. Meanwhile, the second mounting base is equipped with an arc-shaped baffle, and a height scale is set on the outer edge of the arc-shaped baffle to form a surface block to reduce the lateral force generated by the flat pressure here.

[0052] The adhesive application assembly 6 of this utility model includes a mounting frame with lifting function, a film roll end 63, a winding end 62, a tensioning wheel 64, and a cutting mechanism. The cutting mechanism includes a cutting unit, which comprises a stop block 65 mounted on the mounting frame and a flat pressing part 651 disposed at the bottom of the stop block 65. A groove is formed in the middle of the stop block 65 for installing rubber, forming an elastic cutting area 652.

[0053] The cutter unit 61 is mounted on the mounting bracket based on the position of the elastic cutting area 652. In this design, the tape is released from the roll end 63, passes sequentially through the first tension roller 64, the flat pressing section 651, and multiple other tension rollers 64, and is finally retracted by the take-up end 62.

[0054] The gripping component 7 in this invention specifically includes a fourth cylinder, which is installed on the lifting frame 5, and a pneumatic suction cup 72 is installed on the control end of the fourth cylinder.

[0055] The working principle is as follows: Two sets of circular fabrics are placed in the first positioning component 2 and the second positioning component 3 respectively, and a fixed height is set. Adjustment is made by the first cylinder 22 and the second cylinder 32. First, the infrared component 7 moves above the second positioning component 3. The infrared component 7 measures the distance from itself to the surface of the fabric at that point. If the distance is within the preset range, the steering mechanism 34 turns, and the fork structure 33 is positioned directly above the fabric. The third cylinder 71 controls the fork structure 33 to descend, pressing the fabric at that point. The PLC unit controls the lowering frame to descend, causing the flattening section 65 to... 1. Press the double-sided tape onto the fabric, control the sliding end to move to the right, and press the double-sided tape flat onto the circular fabric. At this time, control the sliding end to move to the left, so that the gripping component 7 is above the first positioning component 2. Control the pneumatic suction cup 72 to descend and adsorb the circular fabric at this point and rise. Then move to the right, so that the pneumatic suction cup 72 is above the second positioning component 3. Control the pneumatic suction cup 72 to descend and press against the fabric at this point. Then the pneumatic suction cup 72 rises and moves to the right again to place the bonded fabric into the collection tank 8. Repeat this operation step.

[0056] Furthermore, this utility model embodiment provides a method for bonding round-bottomed fabric, including the following steps:

[0057] S1. Arrange at least two first positioning components 2 and second positioning components 3 for storing circular fabrics, and mark them as the first fabric and the second fabric respectively;

[0058] S2. Move the infrared component 7 directly above the second positioning component 3 and measure its height above the second fabric surface; simultaneously cut the double-sided tape.

[0059] S3. Set the height range value. If the height value is within the height range value, proceed to step S4; otherwise, proceed to step S7.

[0060] S4. Apply double-sided tape to the second fabric surface at this location;

[0061] S5. Grab the first fabric from the first positioning component 2 and place it directly above the second fabric, then press them together to obtain the adhesive fabric.

[0062] S6. Grab and collect the bonded fabric;

[0063] S7. Adjust the height and position of the fabric inside the second positioning component 3, and return to step S2.

[0064] Step S4 further includes:

[0065] S41. Press the second fabric together to obtain a flat adhesive area;

[0066] S42. Starting from one side of the adhesive area, press the double-sided tape against the starting point and flatten it.

[0067] S43. Cancel step S41, causing the fabric piled up by the second positioning component 3 to expand on its own.

[0068] Based on steps S1 to S7, a quality sensor is introduced to acquire data on the changes in fabric quality during the above stages: from the start of fabric gripping, the fabric gripping and bonding stage, to the release stage.

[0069] A dataset is created based on fabric quality variation data. A neural network model is trained to output the trained model, which is then embedded into a PLC unit. Based on the fabric quality data, corresponding operation steps are output. From steps S1 to S7, from fabric grasping to final release, the fabric quality data is linear. By intelligently analyzing this data and matching it with the corresponding execution steps, the execution steps can be corrected. For example, if the fabric falls during grasping, the PLC unit is reset and the process starts again; if the quality data is not the specified value after the fabric bonding stage, the bonding process is repeated. Based on this, the solution of this invention is more intelligent.
