[0002] In the current production process of dust filter bags, the production of the bag bottom is a crucial link, which is directly related to the sewing strength and sealing performance of the filter bag. The traditional process is to sew a double layer of round cloth on the bag bottom to ensure the stability of the structure and the reliability of the seal. However, this process has obvious efficiency bottlenecks and labor intensity problems during implementation.

[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 lot of manual operations, including tearing off the double-sided tape, pasting, aligning the fabric, and other simple but repetitive labor. This labor-intensive production method not only reduces production efficiency, but also increases the labor intensity of workers, which is not conducive to long-term production stability and cost control.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0037] like Figures 1 to 3 As shown, an embodiment of the present invention provides an automatic bonding device for round-bottomed fabrics, which includes a base 1, a first positioning component 2, a second positioning component 3, a track component 4, an infrared component 7, a grabbing component 7, a glue-applying component 6 and a PLC unit, wherein 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 grabbing component 7, and the glue-applying component 6, respectively.

[0038] The track component 4 is installed on the base 1, and the first positioning component 2 and the second positioning component 3 are installed on the base 1 according to designated positions, respectively, and are used to store circular cloths. The installation position of the track component 4 is adapted to the installation position of the first positioning component 2 and the second positioning component 3. The grabbing component 7 is used to grab the cloth from the first positioning component 2 and press it against the cloth in the second positioning component 3. Under the action of the double-sided tape, the two circular cloths are bonded, and the bonded cloth is grabbed from the second positioning component 3 again and placed in the collecting trough 8.

[0039] In the present invention, the travel distances of the working ends of the grabbing component 7 and the gluing component 6 are respectively controlled based on the measurement data, the PLC unit presets the travel of the track component 4, and the PLC unit controls the heights of the round cloths stored in the first positioning component 2 and the second positioning component 3. That is, the above scheme adopts an automated method, which can effectively achieve the bonding of round bottom cloths, and introduces an intelligent scheme, so that the equipment can be stopped and used immediately, and the traditional execution process can be modified, making the automated scheme more perfect.

[0040] In some embodiments, a sensor (not shown in the figure) may also be included. The sensor is connected to the grasping component 7 and is used to measure the quality data of the cloth grasped by the grasping component. The PLC unit is embedded in a neural network model, and a quality data component data set is obtained based on the sensor. The neural network model is trained and the trained neural network model is output so that the quality data corresponds to the execution steps. The quality data is obtained based on the sensor, and a corresponding execution signal is output. The PLC unit executes the corresponding operation based on the execution signal. If the quality data is always 0, it means that the grasping has failed. If the quality data is always the quality data of a cloth, it means that the bonding is unsuccessful and needs to be re-bonded or troubleshooting is required.

[0041] The grabbing assembly 7 is installed on the lifting frame 5. The lifting frame 5 of the track assembly 4 moves in the horizontal direction. The grabbing direction of the grabbing assembly 7 is downward. The infrared assembly 7 measures the distance from the surface of the fabric and sends the distance to the PLC unit. The PLC unit controls the descending distance of the suction cup and the descending height of the glue sticking assembly 6. The infrared assembly 7 is installed on the lifting frame 5, and its infrared emission direction is downward. The glue sticking assembly 6 is installed on the lifting frame 5 and is used to press the double-sided tape on the bonding area of ​​the fabric.

[0042] In the present invention, the specific structure of the first positioning assembly 2 includes a first mounting seat, a first cylinder 22, and a first limiting column 21, wherein

[0043] The first mounting seat is mounted on the base 1.

[0044] The first cylinder 22 is electrically connected to the PLC unit, and a support plate is installed at its control end. Three first limiting columns 21 are provided and installed on the first mounting seat. The first cylinder 22 is vertically installed on the first mounting seat and is located in the triangular area formed by the first limiting columns 21. Through the movement of the control end of the first cylinder 22 and the combination with the first limiting columns 21, a storage area with adjustable storage height is formed.

[0045] In actual use, when the cloth in the positioning assembly 7 is gradually removed, the height of the cloth accumulation decreases, so the suction cup needs to be started to descend for a longer distance, and the required grasping time is longer. Therefore, by adjusting the storage height of the above-mentioned accommodation area, the above-mentioned time can be effectively saved, and the above-mentioned process can be replaced by the first cylinder 22.

[0046] The second positioning component 3 has a similar structure to the first positioning component 2, including a second mounting seat, a second cylinder 32, and a second limiting column 31. The second cylinder 32 is electrically connected to the PLC unit. Three second limiting columns 31 are provided and installed on the second mounting seat. Unlike the first positioning component 2, the bonding stage in the present invention is planned to be completed in the second positioning component 3, including a stage of adhering double-sided tape to the cloth, and a stage of bonding another cloth to the cloth through the double-sided tape. In the stage of adhering the double-sided tape to the cloth, compared with the traditional direct pressure type adhering, the present invention presses the double-sided tape against the surface of the cloth and performs flat pressing, so that the bonding surface of the double-sided tape is tighter and the gap is greatly reduced. Therefore, the steering mechanism 34 is installed at the control end of the third cylinder 71, and the fork structure 33 is installed at the control end of the steering mechanism 34. The third cylinder 71 controls the fork end of the fork to press against the circular cloth in a preset order. The control time is set to when the flat pressing part 651 at the bottom of the stopper 65 presses the double-sided tape against the cloth in the second positioning component 3, the steering mechanism 34 is controlled to turn, and the fork end of the fork is controlled by the third cylinder 71 to descend and press against the cloth in the second positioning component 3. The fork end presses against the surface of the cloth to form a flat bonding area. Subsequently, the flat pressing part 651 presses the double-sided tape against the cloth, and the double-sided tape is flat pressed along one end of the bonding area. At the same time, the second mounting seat is installed with an arc-shaped baffle, and a height dial is set on the outer edge of the arc-shaped baffle for setting up a surface block to mitigate the lateral force generated by the flat pressure here.

[0047] The specific structure of the adhesive component 6 in the present invention includes a mounting frame with a lifting function, a film end 63, a winding end 62, a tension wheel 64, and a rubber cutting mechanism, wherein the rubber cutting mechanism includes a rubber cutting unit, which includes a stopper 65 installed on the mounting frame, a flat pressing portion 651 arranged at the bottom of the stopper 65, and a groove is provided in the middle position of the stopper 65 for installing rubber to form an elastic cutting area 652.

[0048] The cutter unit 61 is mounted on the mounting frame based on the position of the elastic cutting area 652. In this solution, the direction of the tape is that it is released from the film end 63, passes through the first tensioning wheel 64, the flat pressing part 651, and other tensioning wheels 64 in sequence, and finally shrinks from the winding end 62.

[0049] The structure of the grabbing assembly 7 in the present invention specifically includes a fourth cylinder installed on the lifting frame 5, and a pneumatic suction cup 72 installed on the control end of the fourth cylinder.

[0050] The working principle is as follows: two groups of circular cloths are placed in the first positioning assembly 2 and the second positioning assembly 3 respectively, and a fixed height is set, which is adjusted by the first cylinder 22 and the second cylinder 32. First, the infrared assembly 7 moves to the top of the second positioning assembly 3, and the infrared assembly 7 measures the distance from it to the surface of the cloth at that location. If the distance is within the preset range, the steering mechanism 34 turns, and the fork structure 33 is located just above the cloth. The third cylinder 71 controls the fork structure 33 to descend, pressing the cloth at that location, and the PLC unit controls the upper descending frame to descend, so that the flat pressing part 65 1 Press the double-sided tape against the cloth, control the sliding end to move rightward, press the double-sided tape flat against the circular cloth, and then control the sliding end to move leftward, so that the grabbing component 7 is located above the first positioning component 2, control the pneumatic suction cup 72 to descend to absorb the circular cloth there and rise, then move to the right, the pneumatic suction cup 72 is located above the second positioning component 3, control the pneumatic suction cup 72 to descend, and press against the cloth there, then the pneumatic suction cup 72 rises, moves to the right again, and places the bonded cloth into the collecting tank 8, and repeats the operation steps.

[0051] In addition, if Figure 4 and Figure 5 As shown, an embodiment of the present invention also provides a round bottom cloth bonding method, comprising the following steps:

[0052] S1, arranging at least two first positioning components 2 and second positioning components 3 for storing circular cloths, marked as first cloth and second cloth respectively;

[0053] S2, by moving the infrared component 7 to the top of the second positioning component 3, measuring the height value from the infrared component 7 to the second cloth surface; and cutting off the double-sided adhesive tape at the same time;

[0054] S3, set the height interval value, if the height value is within the height interval value, proceed to step S4; otherwise, proceed to step S7;

[0055] S4, bonding the double-sided tape to the second fabric surface at that location;

[0056] S5, grabbing the first fabric from the first positioning assembly 2 to just above the second fabric, and pressing them together to obtain a bonded fabric;

[0057] S6, grabbing the bonded fabric for collection;

[0058] S7, adjusting the height position of the cloth in the second positioning assembly 3, and returning to step S2;

[0059] Step S4 further comprises:

[0060] S41, pressing the second fabric to obtain a flat bonding area;

[0061] S42, taking one side of the bonding area as the starting point, pressing the double-sided tape to the starting point and performing flat pressing;

[0062] S43, canceling step S41, so that the cloth accumulated by the second positioning component 3 expands by itself.

[0063] Based on steps S1 to S7, a mass sensor is introduced to obtain the mass change data of the grabbed cloth at the above stages, from the beginning of grabbing the cloth, to the stage of grabbing the cloth for bonding, to the stage of releasing;

[0064] A data set is created based on the cloth quality change data, trained through a neural network model, and the trained model is output, and the trained model is embedded in a PLC unit, and the corresponding operation steps are output based on the cloth quality data. From step S1 to step S7, the cloth is grabbed to the final release, where the cloth quality data is a linear data. By intelligently analyzing the data and matching it with the corresponding execution steps, the execution steps can be corrected. For example, if the cloth falls during the grabbing process, the PLC unit is reset and starts from the beginning; when the quality data is not the specified data after the cloth bonding stage, it is re-bonded. Based on this, the solution of the present invention is more intelligent.

[0065] It should be noted that, in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
