[0040] Currently, when using a hot air welding machine to weld fabrics, in order to avoid wrinkles in the welding area of ​​the fabric, the operator is required to tighten the fabric to keep the fabric in a taut state. However, when processing to the end of the fabric, the fabric cannot be effectively tightened, resulting in wrinkles at the end of the fabric, resulting in poor fabric processing quality. In addition, manually tightening the fabric increases the operator's workload, resulting in high labor costs.

[0041] In view of the problem that wrinkles easily appear at the ends of the fabric and that manually tightening the fabric increases the workload of the operator, resulting in high labor costs, the present application provides a hot air welding machine, a control method, an apparatus, an equipment and a storage medium, the hot air welding machine comprising: a machine platform for placing a first fabric and a second fabric, wherein the welding area of ​​the first fabric overlaps with the second fabric; a welding mechanism movably arranged on the machine platform, the welding mechanism being used to weld the overlapping parts of the first fabric and the second fabric; a first driving module, the first driving module being used to drive the welding mechanism to move so that the welding mechanism welds the welding area of ​​the first fabric and the second fabric; a tensioning mechanism arranged on the machine platform, the tensioning mechanism comprising a clamping module and A linear drive module, wherein the movable end of the linear drive module is connected to the clamping module, the clamping module is used to clamp the first fabric and the second fabric, and the linear drive module is used to drive the clamping module to move along the moving direction of the welding mechanism to tighten the first fabric and the second fabric; a position detection module is used to detect the first position information of the tensioning mechanism and the second position information of the welding mechanism; a control module, wherein the first drive module, the clamping module, the linear drive module and the position detection module are electrically connected to the control module respectively, and the control module is used to determine the distance state between the welding mechanism and the tensioning mechanism according to the first position information and the second position information, and control the operation of the first drive module, the clamping module and the linear drive module according to the distance state. According to the solution provided by the embodiment of the present application, during the processing, the first and second fabrics are first placed on the machine table. Then, under the action of the control module, the control module controls the operation of the first drive module, thereby driving the welding mechanism to move continuously. The welding mechanism will weld the fabrics during the movement. Moreover, under the action of the control module, the control module controls the operation of the clamping module and the linear drive module in the tensioning mechanism, so that the clamping module clamps the first and second fabrics, and the linear drive module drives the clamping module to move, so that the first and second fabrics are both in a taut state. Moreover, the position detection module detects the first position information of the tensioning mechanism and the second position information of the welding mechanism in real time, thereby determining the distance state between the welding mechanism and the tensioning mechanism. The control module can control the operation of the first drive module, the clamping module, and the linear drive module in stages according to the distance state, thereby achieving targeted optimization of the processing of the fabric end, avoiding wrinkles at the fabric end, and thus improving the processing quality of the fabric. It can be seen that the hot air welding machine provided by the embodiment of the present application can reduce labor costs while improving the processing quality of the fabric.

[0042] The hot air welding machine, control method, device, equipment and storage medium provided in the embodiments of the present application are specifically described through the following embodiments. First, the hot air welding machine in the embodiments of the present application is described.

[0043] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0044] Reference Figures 1 to 6 One embodiment of the present application provides a hot air welding machine, comprising:

[0045] The machine 100 is used to place a first fabric 610 and a second fabric 620 , wherein the welding area of ​​the first fabric 610 overlaps with the second fabric 620 ;

[0046] The welding mechanism 200 is movably disposed on the machine 100 and is used to weld the overlapping portion of the first fabric 610 and the second fabric 620;

[0047] A first driving module 310 is used to drive the welding mechanism 200 to move so that the welding mechanism 200 welds the welding area of ​​the first fabric 610 and the second fabric 620;

[0048] The tensioning mechanism 400 is disposed on the machine 100 and includes a clamping module 410 and a linear drive module 420. The movable end of the linear drive module 420 is connected to the clamping module 410. The clamping module 410 is used to clamp the first fabric 610 and the second fabric 620. The linear drive module 420 is used to drive the clamping module 410 to move along the moving direction of the welding mechanism 200 to tighten the first fabric 610 and the second fabric 620.

[0049] A position detection module 700 is used to detect first position information of the tensioning mechanism 400 and second position information of the welding mechanism 200;

[0050] The control module 500, the first drive module 310, the clamping module 410, the linear drive module 420 and the position detection module 700 are respectively electrically connected to the control module 500. The control module 500 is used to determine the distance state between the welding mechanism 200 and the tensioning mechanism 400 based on the first position information and the second position information, and control the operation of the first drive module 310, the clamping module 410 and the linear drive module 420 based on the distance state.

[0051] It is understandable that when the welding mechanism 200 welds the fabric, in order to improve the welding effect of the fabric, the welding mechanism 200 usually first uses hot air to heat the fabric, and then presses the fabric in the high-temperature state, which is equivalent to one end of the fabric being fixed by the welding mechanism 200. At this time, under the action of the tensioning mechanism 400, the clamping module 410 clamps the first fabric 610 and the second fabric 620, which is equivalent to the other end of the fabric being fixed by the clamping module 410. At the same time, the linear drive module 420 drives the clamping module 410 to clamp the first fabric 610 and the second fabric 620. The module 410 moves along the moving direction of the welding mechanism 200, so that the clamping module 410 can gradually tighten the fabric. When it moves to an appropriate distance, the first fabric 610 and the second fabric 620 can be in a suitable tension state, thereby improving the welding effect of the fabric. Based on this, during the processing, the first fabric 610 and the second fabric 620 are first placed on the machine 100, and then under the action of the control module 500, the control module 500 controls the operation of the first driving module 310, thereby driving the welding mechanism 200 to continue moving. The welding mechanism 200 welds the fabrics during its movement, and under the action of the control module 500, the control module 500 controls the operation of the clamping module 410 and the linear drive module 420 in the tensioning mechanism 400, so that the clamping module 410 clamps the first fabric 610 and the second fabric 620, and the linear drive module 420 drives the clamping module 410 to move, so that the first fabric 610 and the second fabric 620 are both in a taut state; and the position detection module 700 detects the first position of the tensioning mechanism 400 in real time. The position information and the second position information of the welding mechanism 200 are used to determine the distance state between the welding mechanism 200 and the tensioning mechanism 400. The control module 500 can control the operation of the first driving module 310, the clamping module 410 and the linear driving module 420 in stages according to the distance state, thereby realizing targeted optimization of the processing of the end of the cloth, avoiding wrinkles at the end of the cloth, and thus improving the processing quality of the cloth. It can be seen that the hot air welding machine provided in the embodiment of the present application can improve the processing quality of the cloth while reducing labor costs.

[0052] In addition, refer to Figures 3 to 5In one embodiment, the clamping module 410 includes a first clamp 411, a second clamp 412 and a third clamp 413, and the linear drive module 420 includes a first linear driver 421, a second linear driver 422 and a third linear driver 423. The movable end of the first linear driver 421 is connected to the first clamp 411, the movable end of the second linear driver 422 is connected to the second clamp 412, and the movable end of the third linear driver 423 is connected to the third clamp 413. The first clamp 411 is used to clamp the first cloth 610, the second clamp 412 is used to clamp the second cloth 620, and the third clamp 413 is used to clamp the overlapping part between the first cloth 610 and the second cloth 620.

[0053] Among them, the first linear drive 421 is used to drive the first clamp 411 to move along the moving direction of the welding mechanism 200, the second linear drive 422 is used to drive the second clamp 412 to move along the moving direction of the welding mechanism 200, and the third linear drive 423 is used to drive the third clamp 413 to move along the moving direction of the welding mechanism 200.

[0054] It can be understood that by providing the first clamp 411, the second clamp 412 and the third clamp 413, the fabric can be fixed at multiple points to improve the flatness of the fabric. Specifically, the first clamp 411 specifically clamps the first fabric 610, the second clamp 412 specifically clamps the second fabric 620, and the third clamp 413 clamps the first fabric 610 and the second fabric 620 at the same time. Since the third clamp 413 needs to clamp the first fabric 610 and the second fabric 620 at the same time, the third clamp 413 clamps the overlapping portion between the first fabric 610 and the second fabric 620. In addition, since The first clamp 411, the second clamp 412 and the third clamp 413 are set at different positions, and independent drives are required for the first clamp 411, the second clamp 412 and the third clamp 413. Therefore, the linear drive module 420 includes a first linear drive 421, a second linear drive 422 and a third linear drive 423. The first linear drive 421 is dedicated to driving the first clamp 411, the first linear drive 421 is dedicated to driving the first clamp 411, the second linear drive 422 is dedicated to driving the second clamp 412, and the third linear drive 423 is dedicated to driving the third clamp 413.

[0055] It is worth noting that the control module 500 can control the first clamp 411 to loosen to place the first cloth 610, the control module 500 can control the second clamp 412 to loosen to place the second cloth 620, and the control module 500 can control the third clamp 413 to loosen to place the first cloth 610 and the second cloth 620.

[0056] In addition, refer to Figure 2 、 Figure 4、 Figure 5 、 Figure 10 In one embodiment, the position detection module 700 includes a first proximity sensor 710 and a second proximity sensor 720. The first proximity sensor 710 is arranged on the welding mechanism 200, and the second proximity sensor 720 is arranged on the third clamp 413. The first proximity sensor 710 is used to detect the first position information of the first clamp 411 or the second clamp 412, and the second proximity sensor 720 is used to detect the second position information of the welding mechanism 200, wherein the distance between the first clamp 411 and the welding mechanism 200 is equal to the distance between the second clamp 412 and the welding mechanism 200, and the distance between the first clamp 411 and the welding mechanism 200 is greater than the distance between the third clamp 413 and the welding mechanism 200.

[0057] It can be understood that by setting the first proximity sensor 710 on the welding mechanism 200, it is possible to effectively detect whether the welding mechanism 200 is close to the first clamp 411 or the second clamp 412. In addition, by setting the second proximity sensor 720 on the third clamp 413, it is possible to effectively detect whether the third clamp 413 is close to the welding mechanism 200.

[0058] It should be noted that, since the distance between the first clamp 411 and the welding mechanism 200 is equal to the distance between the second clamp 412 and the welding mechanism 200, and the distance between the first clamp 411 and the welding mechanism 200 is greater than the distance between the third clamp 413 and the welding mechanism 200, the welding mechanism 200 will first pass through the first clamp 411 and the second clamp 412 during the movement. After the welding mechanism 200 passes through the first clamp 411 and the second clamp 412, in order to completely weld the fabric, under the action of the control module 500, the control module 500 controls the third clamp 413 to release, and controls the third linear drive 423 to reset, which is equivalent to moving the third clamp 413 away from the welding mechanism 200. The welding mechanism 200 can weld the overlapping part of the fabric originally clamped by the third clamp 413. At the same time, the first clamp 411 and the second clamp 412 both ensure that the fabric is in a taut state, thereby ensuring the flatness of the entire fabric.

[0059] It is worth noting that in order to improve the detection accuracy of the first proximity sensor 710, a first object to be detected 810 with identification is provided on the first clamp 411 or the second clamp 412. When the first proximity sensor 710 approaches the first object to be detected 810, the electrical signal generated by the first proximity sensor 710 will change significantly, and then the first position information detected by the first proximity sensor 710 is used to determine that the welding mechanism 200 is close to the first clamp 411 or the second clamp 412; in addition, in order to improve the detection accuracy of the second proximity sensor 720, a second object to be detected 820 with identification is provided on the welding mechanism 200. When the second proximity sensor 720 approaches the second object to be detected 820, the electrical signal generated by the second proximity sensor 720 will change significantly, and then the second position information detected by the second proximity sensor 720 is used to determine that the welding mechanism 200 is close to the welding mechanism 200.

[0060] In addition, refer to Figure 7 In one embodiment, the tensioning mechanism 400 also includes a second vertical support arm 430 and a second horizontal bracket 440, one end of the second vertical support arm 430 is set on the machine 100, the second horizontal bracket 440 is fixed to the other end of the second vertical support arm 430, and the first linear drive 421, the second linear drive 422 and the third linear drive 423 are fixed to the bottom of the second horizontal bracket 440.

[0061] It can be understood that fixing the second horizontal bracket 440 to the other end of the second vertical support arm 430 can increase the height of the second horizontal bracket 440, and thereby increase the height of the first linear drive 421, the second linear drive 422 and the third linear drive 423, thereby ensuring the normal operation of the first linear drive 421, the second linear drive 422 and the third linear drive 423, as well as the normal operation of the first clamp 411, the second clamp 412 and the third clamp 413. Moreover, the second vertical support arm 430 is vertically arranged and the second horizontal bracket 440 is horizontally arranged, which can improve the stability of the tensioning mechanism 400.

[0062] In addition, refer to Figure 7In one embodiment, a first clamping switch 441, a second clamping switch 442, a third clamping switch 443, a first moving switch 444, a second moving switch 445 and a third moving switch 446 are provided on the second horizontal bracket 440. The first clamping switch 441, the second clamping switch 442, the third clamping switch 443, the first moving switch 444, the second moving switch 445 and the third moving switch 446 are electrically connected to the control module 500 respectively. The first clamping switch 441 is used to control the working state of the first clamp 411, the second clamping switch 442 is used to control the working state of the second clamp 412, the third clamping switch 443 is used to control the working state of the third clamp 413, the first moving switch 444 is used to control the working state of the first linear drive 421, the second moving switch 445 is used to control the working state of the second linear drive 422, and the third moving switch 446 is used to control the working state of the third linear drive 423.

[0063] It can be understood that by setting the first clamping switch 441, the second clamping switch 442, the third clamping switch 443, the first moving switch 444, the second moving switch 445 and the third moving switch 446, the operator can directly control the tensioning mechanism 400 near the machine 100, which can improve work efficiency and is highly practical.

[0064] In addition, refer to Figure 7 In one embodiment, a second driving module 320 is further included. A main rail 110 is provided on one side of the machine 100, and a rack 111 is provided on the upper surface of the main rail 110. The second driving module 320 is provided at one end of the second vertical support arm 430. The second driving module 320 includes a second servo motor 321 and a second gear 322 engaged with the rack 111. The second gear 322 is provided at the movable end of the second servo motor 321. The second servo motor 321 is electrically connected to the control module 500. The second servo motor 321 is used to drive the second gear 322 to move on the rack 111 to drive the tensioning mechanism 400 to move.

[0065] It can be understood that by setting the rack 111 and the second gear 322, the smoothness of the movement of the tensioning mechanism 400 can be improved. Under the action of the control module 500, the second servo motor 321 can accurately control the movement process of the tensioning mechanism 400, and the main rail 110 can support the tensioning mechanism 400.

[0066] In addition, refer to Figure 8In one embodiment, the welding mechanism 200 includes a first vertical arm 210, a first horizontal bracket 230 and a welding module 220. The first vertical arm 210 is parallel to the second vertical arm 430, and the first horizontal bracket 230 is parallel to the second horizontal bracket 440. One end of the first vertical arm 210 is movably set on the machine 100, and the other end of the first vertical arm 210 is fixedly connected to one end of the first horizontal bracket 230. The welding module 220 is fixed to the other end of the first horizontal bracket 230.

[0067] It can be understood that fixing one end of the first horizontal bracket 230 to the other end of the first vertical support arm 210 can increase the height of the first horizontal bracket 230, and then increase the height of the welding module 220, ensuring that the welding module 220 can effectively weld the fabric. Moreover, the first vertical support arm 210 is vertically arranged and the first horizontal bracket 230 is horizontally arranged, which can improve the stability of the welding mechanism 200.

[0068] In addition, refer to Figure 8 In one embodiment, the first driving module 310 is arranged at one end of the first vertical support arm 210. The first driving module 310 includes a first servo motor 311 and a first gear 312 engaged with the rack 111. The first gear 312 is arranged at the movable end of the first servo motor 311. The first servo motor 311 is electrically connected to the control module 500. The first servo motor 311 is used to drive the first gear 312 to move on the rack 111 to drive the welding mechanism 200 to move.

[0069] It can be understood that by providing the rack 111 and the first gear 312, the smoothness of the movement of the welding mechanism 200 can be improved. Under the action of the control module 500, the first servo motor 311 can accurately control the movement process of the welding mechanism 200, and the main rail 110 can support the welding mechanism 200.

[0070] In addition, refer to Figure 7 and Figure 8 In one embodiment, a first auxiliary guide rail 120 and a second auxiliary guide rail 130 are provided on one side of the machine 100, and the first auxiliary guide rail 120 and the second auxiliary guide rail 130 are respectively parallel to the main rail 110, and the first vertical support arm 210 is provided with a first guide head 211 and a second guide head 212, the first guide head 211 slides with the first auxiliary guide rail 120, and the second guide head 212 slides with the second auxiliary guide rail 130, and the second vertical support arm 430 is provided with a third guide head 431 and a fourth guide head 432, the third guide head 431 slides with the first auxiliary guide rail 120, and the fourth guide head 432 slides with the second auxiliary guide rail 130.

[0071] It can be understood that by providing the first auxiliary guide rail 120 and the second auxiliary guide rail 130 on the machine 100, and providing the first guide head 211 matching the first auxiliary guide rail 120 on the first vertical support arm 210, and also providing the second guide head 212 matching the second auxiliary guide rail 130 on the first vertical support arm 210, the welding mechanism 200 can be effectively supported to prevent the welding mechanism 200 from falling. In addition, by providing the third guide head 431 matching the first auxiliary guide rail 120 on the second vertical support arm 430, and also providing the fourth guide head 432 matching the second auxiliary guide rail 130 on the second vertical support arm 430, the tensioning mechanism 400 can be effectively supported to prevent the tensioning mechanism 400 from falling.

[0072] In addition, refer to Figure 9 and Figure 10 In one embodiment, the welding mechanism 200 includes a guide 221, a hot air gun 223, a pressing wheel 224 and a gun body driving assembly 225. The guide 221 is located between the pressing wheel 224 and the tensioning mechanism 400, and the hot air gun 223 is located between the pressing wheel 224 and the guide 221. One end of the guide 221 is in contact with the second fabric 620. A guide opening 222 is provided at one end of the guide 221. The welding area of ​​the first fabric 610 passes through the guide opening 222. The gun body driving assembly 225 is used to drive the hot air gun 223 to move below the welding area of ​​the first fabric 610. The pressing wheel 224 is used to press the overlapping portion of the first fabric 610 and the second fabric 620.

[0073] It can be understood that during the welding process of the fabrics, the gun body drive assembly 225 will drive the hot air gun 223 to move to the bottom of the welding area of ​​the first fabric 610. At this time, the hot air gun 223 is located between the first fabric 610 and the second fabric 620. The hot air gun 223 can effectively heat the first fabric 610 and the second fabric 620, and then the pressing wheel 224 presses the first fabric 610 and the second fabric 620 at high temperature. In addition, before the hot air gun 223 heats the first fabric 610 and the second fabric 620, the first fabric 610 needs to pass through the guide opening 222 to separate the first fabric 610 and the second fabric 620, so that there is a gap between the first fabric 610 and the second fabric 620, which facilitates the hot air gun 223 to heat the first fabric 610 and the second fabric 620.

[0074] Specifically, the gun body drive assembly 225 may include a linear push rod and a rotary driver. The linear push rod is connected to the movable end of the rotary driver, and the hot air gun 223 is connected to the movable end of the linear push rod. The linear push rod is used to push the hot air gun 223 downward to approach the table of the machine 100. The rotary driver is used to rotate the hot air gun 223 so that the hot air gun 223 can move to the bottom of the welding area of ​​the first fabric 610. After the welding is completed, the rotary driver first rotates the hot air gun 223, and then the linear push rod moves the hot air gun 223 to the initial position, thereby resetting the hot air gun 223.

[0075] In addition, refer to Figure 11 and Figure 12 In one embodiment, in some embodiments, the welding mechanism 200 includes a guide wheel 226, a hot air gun 223, and a pressing wheel 224. The machine 100 is further used to place the third fabric 640. The first fabric 610 and the second fabric 620 are integrated into a base fabric 630. The welding area of ​​the third fabric 640 overlaps with the base fabric 630. The air outlet of the hot air gun 223 faces the welding area of ​​the third fabric 640. The guide wheel 226 is located above the pressing wheel 224, between the pressing wheel 224 and the tensioning mechanism 400, and the hot air gun 223 is located between the guide wheel 226 and the pressing wheel 224. The guide wheel 226 is used to guide the third fabric 640 to fit the base fabric 630. The pressing wheel 224 is used to press the overlapping portion of the third fabric 640 and the base fabric 630.

[0076] It can be understood that the entirety of the first fabric 610 and the second fabric 620 is considered the base fabric 630, the base fabric 630 is placed on the table of the machine 100, and the first part, the second part, and the third part are sequentially distributed on the base fabric 630. The first clamp 411 clamps the first part of the base fabric 630, the second clamp 412 clamps the third part of the base fabric 630, and the third clamp 413 clamps the second part of the base fabric 630, thereby The base fabric 630 is effectively fixed. During the welding process, under the action of the tensioning mechanism 400, the base fabric 630 is in a taut state, and the guide wheel 226 guides the third fabric 640 to fit together with the base fabric 630. Then, the hot air gun 223 heats the third fabric 640 and the base fabric 630 at the same time, and the pressing wheel 224 presses the third fabric 640 and the base fabric 630 at high temperature, thereby completing the welding of the third fabric 640 and the base fabric 630.

[0077] Based on this, before welding the fabrics, if the first fabric 610 and the second fabric 620 are separate, the first fabric 610, the second fabric 620 and the third fabric 640 are welded together at the same time; if the first fabric 610 and the second fabric 620 are an integrated base fabric 630, the third fabric 640 and the base fabric 630 are welded together.

[0078] like Figure 13 As shown, Figure 13 This is an optional flow chart of a control method for a hot air welding machine provided in an embodiment of the present application. The control method for a hot air welding machine can be applied to the above-mentioned hot air welding machine. The hot air welding machine includes a machine platform, a welding mechanism, a first drive module, a tensioning mechanism, a position detection module, and a control module. The tensioning mechanism includes a clamping module and a linear drive module. The control method for the hot air welding machine includes but is not limited to the following steps:

[0079] S1301, obtaining first position information of the tensioning mechanism and second position information of the welding mechanism;

[0080] S1302, determining a distance state between the welding mechanism and the tensioning mechanism based on the first position information and the second position information;

[0081] S1303: Control the operation of the first driving module, the clamping module, and the linear driving module according to the distance state.

[0082] It can be understood that since the control method of the hot air welding machine in this embodiment is applied to the hot air welding machine mentioned in the above specific embodiment, the control method of the hot air welding machine in this embodiment has the beneficial effects brought by the hot air welding machine mentioned in the above specific embodiment.

[0083] In addition, refer to Figure 14 In one embodiment, the clamping module includes a first clamp, a second clamp and a third clamp, the linear drive module includes a first linear drive, a second linear drive and a third linear drive, the movable end of the first linear drive is connected to the first clamp, the movable end of the second linear drive is connected to the second clamp, and the movable end of the third linear drive is connected to the third clamp, the position detection module includes a first proximity sensor and a second proximity sensor, the first proximity sensor is arranged on the welding mechanism, and the second proximity sensor is arranged on the third clamp, the first proximity sensor is used to detect the first position information of the first clamp or the second clamp, and the second proximity sensor is used to detect the second position information of the welding mechanism, the distance between the first clamp and the welding mechanism is equal to the distance between the second clamp and the welding mechanism, and the distance between the first clamp and the welding mechanism is greater than the distance between the third clamp and the welding mechanism; Figure 13 Step S1302 in the illustrated embodiment includes but is not limited to the following steps:

[0084] Step S1401: When the first position information indicates that the distance between the welding mechanism and the first clamp or the second clamp is greater than or equal to a preset first distance threshold, determining that the distance state between the welding mechanism and the tensioning mechanism is in a long-distance state;

[0085] Step S1402: When the first position information indicates that the distance between the welding mechanism and the first clamp or the second clamp is less than a first distance threshold, and the second position information indicates that the distance between the third clamp and the welding mechanism is greater than or equal to a preset second distance threshold, determining that the distance between the welding mechanism and the tensioning mechanism is in a medium distance state;

[0086] Step S1403 : When the second position information indicates that the distance between the third clamp and the welding mechanism is greater than or equal to a second distance threshold, it is determined that the distance between the welding mechanism and the tensioning mechanism is in a close distance state.

[0087] It can be understood that during the welding process, the control module will control the first drive module, the clamping module and the linear drive module in three stages. The first stage refers to the distance state between the welding mechanism and the tensioning mechanism being in a long-distance state, the second stage refers to the distance state between the welding mechanism and the tensioning mechanism being in a medium-distance state, and the third stage refers to the distance state between the welding mechanism and the tensioning mechanism being in a close-distance state. Through stage-by-stage control, targeted optimization of the processing of the cloth end is achieved to avoid wrinkles at the cloth end, thereby improving the processing quality of the cloth.

[0088] Among them, the distance between the welding mechanism and the first clamp or the second clamp is greater than or equal to the preset first distance threshold, which means that the distance between the welding mechanism and the first clamp is greater than or equal to the preset first distance threshold, or the distance between the welding mechanism and the second clamp is greater than or equal to the first distance threshold; similarly, the distance between the welding mechanism and the first clamp or the second clamp is less than the first distance threshold, which means that the distance between the welding mechanism and the first clamp is less than the first distance threshold, or the distance between the welding mechanism and the second clamp is less than the first distance threshold.

[0089] Among them, a first object to be measured with identification can be provided on the first clamp or the second clamp, and the first proximity sensor can determine the distance between the welding mechanism and the first clamp or the second clamp by detecting the first position information of the first object to be measured. For example, the first object to be measured is a first metal sheet parallel to the front side of the welding mechanism. When the welding mechanism is away from the first clamp and the second clamp, the distance between the welding mechanism and the first clamp or the second clamp is greater than or equal to the first distance threshold. When the welding mechanism moves toward the tensioning mechanism, the distance between the welding mechanism and the first clamp or the second clamp will gradually decrease. When the distance between the welding mechanism and the first clamp or the second clamp is less than the first distance threshold, the distance between the welding mechanism and the first clamp or the second clamp will gradually decrease. When a threshold is set, for example, the first distance threshold is 2 cm, which means that the welding mechanism is close to the first clamp or the second clamp, and after the welding mechanism moves between the first clamp or the second clamp, the welding mechanism can continue to move between the first clamp or the second clamp, thereby welding the end of the fabric. When the welding mechanism moves between the first clamp or the second clamp, since the first metal sheet is parallel to the front side of the welding mechanism, it is equivalent to that the distance between the welding mechanism and the first clamp or the second clamp remains unchanged. Therefore, the first position information detected by the first proximity sensor does not change, and the distance between the welding mechanism and the first clamp or the second clamp remains less than the first distance threshold.

[0090] Among them, a second object to be detected with identification can be set on the welding mechanism, and the second proximity sensor can determine the distance between the third clamp and the welding mechanism by detecting the second position information of the second object to be detected. When the distance between the third clamp and the welding mechanism is greater than or equal to the second distance threshold, it means that the welding mechanism is still in a state away from the third clamp, and the welding mechanism will not touch the third clamp during the movement. For example, the second distance threshold is 2 cm. When the welding mechanism continues to move in the original direction, the distance between the third clamp and the welding mechanism will gradually decrease. When the distance between the third clamp and the welding mechanism is less than the second distance threshold, it means that the welding mechanism is still close to the third clamp. Assuming that the welding mechanism continues to move, the welding mechanism will touch the third clamp. Therefore, when the distance between the third clamp and the welding mechanism is less than the second distance threshold, it is necessary to control the third clamp to release the fabric and drive the third clamp away from the welding mechanism.

[0091] In addition, refer to Figure 15 In one embodiment, Figure 13 Step S1303 in the illustrated embodiment includes but is not limited to the following steps:

[0092] Step S1501, when the distance state is in the long distance state, determining a first speed of the welding mechanism, and controlling the operation of the first driving module, the clamping module, and the linear driving module based on the first speed;

[0093] Step S1502, when the distance state is in the medium distance state, determining a second speed of the welding mechanism, and controlling the operation of the first driving module, the clamping module, and the linear driving module based on the second speed;

[0094] Step S1503: When the distance state is in the close distance state, determining a third speed of the welding mechanism, and controlling the operation of the first driving module, the clamping module, and the linear driving module based on the third speed.

[0095] The second speed is lower than the first speed, and the third speed is lower than the second speed.

[0096] It can be understood that in the first stage, that is, when the distance state is in the long-distance state, the distance between the welding module and the end of the cloth is relatively far, and the control module controls the welding mechanism to move at a first speed with a higher speed, so that the non-end part of the cloth can be quickly welded; in the second stage, that is, when the distance state is in the medium-distance state, the distance between the welding module and the end of the cloth is relatively close. At this time, the first clamp is closer to the welding mechanism, and the tension of the first cloth is relatively weak. Similarly, the second clamp is closer to the welding mechanism, and the tension of the second cloth is relatively weak. By reducing the moving speed of the welding mechanism, the control module controls the welding mechanism to move at a second speed with a moderate speed, thereby avoiding wrinkles at the end of the cloth; in the third stage, that is, when the distance state is in the short-distance state, the welding module performs welding processing on the end of the cloth. At this time, it is necessary to further reduce the moving speed of the welding mechanism. The control module controls the welding mechanism to move at a third speed with a lower speed, thereby avoiding wrinkles at the end of the cloth, thereby improving the processing quality of the cloth.

[0097] Exemplarily, the first speed may be 2 meters per minute to 5 meters per minute, the second speed may be 90% of the first speed, and the third speed may be 75% of the first speed, which can avoid wrinkles at the ends of the cloth, thereby improving the processing quality of the cloth.

[0098] In addition, refer to Figure 16 In one embodiment, the machine is used to place a first fabric and a second fabric, and the welded area of ​​the first fabric overlaps with the second fabric; Figure 15 Step S1503 in the illustrated embodiment includes but is not limited to the following steps:

[0099] Step S1601, generating a first drive instruction, a second drive instruction, a third drive instruction, a fourth drive instruction, a fifth drive instruction, a sixth drive instruction, and a seventh drive instruction based on the third speed;

[0100] Step S1602: sending a first driving instruction to the first driving module, so that the first driving module drives the welding mechanism to move at a third speed;

[0101] Step S1603: sending a second driving instruction to the first clamp to enable the first clamp to clamp the first cloth;

[0102] Step S1604: sending a third driving instruction to the second clamp to enable the second clamp to clamp the second fabric;

[0103] Step S1605: sending a fourth driving instruction to the third clamp to release the third clamp;

[0104] Step S1606, sending a fifth driving instruction to the first linear actuator to tighten the first fabric;

[0105] Step S1607, sending a sixth driving instruction to the second linear actuator to tighten the second fabric;

[0106] Step S1608: Send a seventh driving instruction to the third linear driver to reset the third linear driver.

[0107] It can be understood that in the third stage, since the welding module welds the end of the cloth, the control module controls the third clamp to loosen and controls the third linear drive to reset, which is equivalent to moving the third clamp away from the welding mechanism. The welding mechanism can weld the overlapping part of the cloth originally clamped by the third clamp. At this time, the tension of the first cloth and the second cloth is further reduced. Therefore, it is necessary to further reduce the moving speed of the welding mechanism to avoid wrinkles at the end of the cloth, thereby improving the processing quality of the cloth. At the same time, the first clamp and the second clamp both ensure that the cloth is taut, thereby ensuring the flatness of the entire cloth.

[0108] In addition, reference Figure 17 The present application also provides a control device 1700 for a hot air welding machine. The control device 1700 for a hot air welding machine can be applied to the above-mentioned hot air welding machine.

[0111] The control unit 1703 is used to control the operation of the first driving module, the clamping module and the linear driving module according to the distance state.

[0112] It can be understood that the specific implementation of the control device 1700 of the hot air welding machine is basically the same as the specific embodiment of the control method of the hot air welding machine mentioned above, and will not be repeated here.
