Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment manufacturing, and more specifically, to an automatic wool strip threading and bending device and a control method thereof. Background Art

[0002] The fuselage of the commonly used air conditioner cabinet unit is divided into conventional units and single-flow units according to the structure. The conventional unit has a rectangular shape, and the single-flow unit has a cylindrical shape. At present, single-flow units are increasingly favored by consumers, but due to the structural problems of single-flow units, the deformation of the air outlet panel needs to be corrected by bending the selected profile. The correction range is determined by the deformation of the air outlet plate, and the deformation of each batch of air outlet plates is different. Therefore, for each batch of air outlet plates, the process and quality control need to be adjusted to adjust the bending range of the bending tooling.

[0003] This adjustment mode requires different operators to complete. For example, employee A unpacks the selected profile and wool strips, and then inserts the wool strips into the grooves of the selected profiles. Then, employee B in the next process bends the selected profiles with wool strips. There are three bending points for the selected profiles, and each point needs to pause for about three seconds during bending to ensure the curvature of the bend. At present, simple tooling is used for bending the selected profiles. The bending range of the tooling must be adjusted by the process debugging personnel before the operator can operate it.

[0004] Therefore, the existing automatic threading machine bending method has the following problems:

[0005] 1) The production method is backward and the production staff is intensive;

[0006] 2) The process debugging of the bending tooling and the bending operation of the operator cannot be carried out at the same time. When the process debugging personnel adjust the bending curvature, the operator needs to wait for the bending curvature to be adjusted before operating, resulting in a waste of personnel and working hours;

[0007] 3) When the process debugging personnel adjust the bending curvature of the bending tooling, the bending curvature cannot be quantified;

[0008] 4) The operator’s pause time during bending cannot be quantified, and the bending curvature of the selected profile cannot be guaranteed. Summary of the invention

[0057] The present invention will be further described below in conjunction with the accompanying drawings.

[0058] Figure 1 An automatic wool threading and bending device according to the present application is shown. Figure 2 Shows Figure 1 Schematic diagram of the enlarged structure of area A in the middle.

[0059] like Figure 1 As shown, the automatic wool strip threading and bending device includes a first feeding assembly, a positioning assembly, a second feeding assembly and a pressure applying assembly.

[0060] The positioning assembly is used to fix the selected profile 20, the first feeding assembly is used to insert the wool strip 10 into the selected profile, the second feeding assembly is used to move the selected profile 20 with the wool strip 10 to the position corresponding to the pressing assembly, and the pressing assembly is used to press the selected profile 20 with the wool strip 10 to form an arc.

[0061] The first feeding assembly, the positioning assembly, the second feeding assembly and the pressure-applying assembly are all arranged on a workbench 1 , and the workbench 1 includes a work surface 11 and a storage cabinet 12 .

[0062] Specifically, Figure 1 and Figure 2As shown, the first feeding assembly includes a accumulator 210, a feeding pusher 211 and a linear drive mechanism 212. Preferably, the linear drive mechanism 212 is a rodless cylinder. The accumulator 210 is arranged on the work surface 11, and is used to store the wool tops 10 and provide the stored wool tops 10 to the feeding pusher 211. The feeding pusher 211 is arranged on the right side of the accumulator 210, and is used to push the wool tops 10 in the accumulator 210 into the selected profile 20. Among them, a positioning component 214 for positioning the wool tops 10 is provided at the bottom of the accumulator 210. When the feeding pusher 211 pushes the wool tops 10 to move, the positioning component 214 is used to limit the unnecessary movement of the wool tops 10. The rodless cylinder 212 is connected to the feeding pusher 211, and is used to provide power for the feeding pusher 211. The rodless cylinder 212 is fixed on the cylinder fixing plate 213, and the cylinder fixing plate 213 is fixed on the accumulator plate 2101.

[0063] In this embodiment, the accumulator 210 includes a storage plate 2101 configured to be at a certain angle to the horizontal plane, and the storage plate 2101 is fixed on the work surface 11 by a fixed platform 2105. When wool strips are put into the storage plate 2101, the wool strips 10 entering from the feeding port 2106 can slide along the surface of the storage plate 2101 toward the bottom of the storage plate 2101. Preferably, the accumulator 210 also includes a pressing plate 2102, which is arranged above the storage plate 2101 and is used to press the wool strips 10 on the storage plate 2101.

When the adjusting plate 2103 is retracted to the desired position, the adjusting plate 2103 is fixed to the storage plate 2101 by adjusting screws.

[0064] exist Figure 1 In the illustrated embodiment, the hopper 210 further includes a first sensor 2104 (see Figure 2 ), the first sensor 2104 is arranged on one side of the rodless cylinder 212 close to the cylinder fixing plate 213, therefore, the first sensor 2104 can be called the rodless cylinder in-situ sensor. When the process of the rodless cylinder 212 pushing a wool strip 10 to the selected profile is completed, the rodless cylinder 212 returns to the initial position (the starting node of the next process) and touches the first sensor 2104, so that the in-situ sensor can obtain the signal that the rodless cylinder 212 returns to the initial position.

[0065] exist Fig. 9In the illustrated embodiment, the positioning assembly includes a clamp 221, a clamp manipulator 222 and a first lifting mechanism 311. The clamp 221 is used to clamp the selected profile 20. When the clamp 221 is located at a position corresponding to the feeding pusher 211 on the left side of the accumulator 210, the feeding pusher 211 can push the wool strip 10 into the selected profile 20. The clamp manipulator 222 can be a cylinder, a hydraulic cylinder or a motor-driven screw, etc. Preferably, the clamp manipulator 222 is a positioning cylinder.

[0066] The clamp 221 includes a first sub-clamp 2211 and a second sub-clamp 2212. The positioning cylinder 222 is connected to the first sub-clamp 2211 and / or the second sub-clamp 2212, and is used to drive the first sub-clamp 2211 and / or the second sub-clamp 2212 to move closer to or farther from each other. The first lifting mechanism 311 is connected to the positioning cylinder 222, and is used to drive the positioning cylinder 222 to move up and down, thereby driving the clamp 221 to move up and down so that the selected profile 20 with the wool strip held by the clamp 221 can be located on the lower mold block 3222. In one embodiment, the first lifting mechanism 311 is a positioning upper and lower cylinder.

[0067] exist Figure 1 and Figure 3 In the illustrated embodiment, the pressure-applying assembly includes a bracket, a pressing die, and a second lifting mechanism 323 .

[0068] The support is arranged on the workbench 1. Figure 3 and Figure 4 As shown, the bracket includes a first base 13, a second base 14 and a fixed base 325. The first base 13 and the second base 14 are both arranged on the work surface 11. The first base 13 can translate relative to the second base 14 to adjust the distance between the first base 13 and the second base 14 to accommodate selected profiles 20 of different lengths. Preferably, the first base 13 and the second base 14 are both configured as groove-type structures.

[0069] In this embodiment, the first base 13 is driven by an adjusting cylinder to move closer to or farther from the second base 14, thereby adjusting the distance between the first base 13 and the second base 14. Figure 4 and Figure 6 As shown, a lower slider connecting plate 132 is provided at the bottom of the first base 13, and the lower slider 133 is fixedly connected to the lower slider connecting plate 132, and the lower slider 133 can slide along the lower rail 134, thereby driving the first base 13 to move along the lower rail 134. Preferably, as Figure 7 As shown, an upper slider 135 is further provided on the top of the first base 13 , and the upper slider 135 can slide along the upper guide rail 136 .

[0070] In this embodiment, if Figure 3As shown, the second base 14 is provided with a wool strip entry port 141 at the position corresponding to the wool strip pushed by the feeding push head, and the first base 13 is provided with a third sensor 131 at the position corresponding to the wool strip, also called a wool strip in place sensor, for detecting whether the wool strip 10 is completely inserted into the selected profile.

[0071] like Figure 1 , Figure 3 , Figure 8 and Fig. 9 As shown, the clamping mold includes an upper mold 321 and a lower mold 322, the upper mold 321 and the lower mold 322 are arranged on a bracket, and the lower mold 322 is located above the table surface of the workbench 1 to allow the feeding fixing plate to pass through the gap between the workbench and the lower mold 322.

[0072] The second lifting mechanism 323 is connected to the upper mold 321 and / or the lower mold 322, and is used to drive the upper mold 321 and / or the lower mold 322 to move closer to or away from each other. In one embodiment, the second lifting mechanism 323 includes a clamping cylinder. Figure 5 As shown, a second sensor 324 is provided on the moving path of the pressing cylinder for detecting whether the pressing cylinder is in place, thereby determining whether the upper mold 321 or the lower mold 322 is in place to ensure that the bending process of the selected profile with the wool strip 10 can achieve the required curvature.

[0073] exist Figure 1 In the illustrated embodiment, the second lifting mechanism 323 is connected to the upper mold 321. When the selected profile 20 needs to be pressed, the second lifting mechanism 323 drives the upper mold 321 to descend and gradually approach the lower mold 322. At this time, the lower mold 322 remains stationary until the upper mold 321 contacts the selected profile 20 and applies pressure to it to bend it into the desired curvature. It can be understood that the second lifting mechanism 323 can also be connected to the lower mold 322. When the selected profile needs to be pressed, the second lifting mechanism 323 drives the lower mold 322 to rise and gradually approach the upper mold 321. At this time, the upper mold 321 remains stationary until the lower mold 322 contacts the selected profile 20 and applies pressure to it to bend it into the desired curvature. It can be understood that the upper mold 321 and the lower mold 322 can also be connected to a second lifting mechanism 323 respectively, and the second lifting mechanism 323 drives the upper mold 321 and the lower mold 322 to approach each other respectively. The subsequent process is the same as above and will not be repeated here.

[0074] like Figure 3 and Figure 8As shown, the upper mold 321 includes an upper bottom plate 3211 and an upper mold block 3212 disposed on the lower surface of the upper bottom plate 3211, and the lower mold 322 includes a lower bottom plate 3221 and a lower mold block 3222 disposed on the upper surface of the lower bottom plate 3221. When pressing the selected profile 20 with the wool strip 10, the upper mold block 3212 and the lower mold block 3222 can correspond to each other to apply pressure to the selected profile 20.

[0075] exist Figure 3 In the illustrated embodiment, the clamping cylinder 323 is disposed on a fixed base plate 325, and a display control system 326 is also disposed on the fixed base plate 325. The display control system 326 is provided with an emergency stop button 327. When uncontrollable factors occur in the device, the emergency stop button 327 can be used to stop the device in an emergency.

[0076] exist Figure 8 and Fig. 9 In the illustrated embodiment, the second feeding assembly includes a feeding fixed plate 312, a slide rail 313, a slider 314 and a driving system 317. The first lifting mechanism 311 is fixed to the two ends of the feeding fixed plate 312, and the slide rail 313 is arranged on the lower surface of the worktable 11 perpendicular to the length direction of the feeding fixed plate 312; the slider 314 is arranged on the slide rail 313, and can drive the feeding fixed plate 312 to move along the slide rail 313 to the position corresponding to the lower mold 322, and then the first lifting mechanism 311 descends to place the selected profile with the wool strip on the lower mold block 3222.

[0077] The lower bottom plate 3221 is located above the feed fixing plate 312 , and channels 3223 are configured on the lower bottom plate 3221 at positions corresponding to the two ends of the feed fixing plate 312 to allow the feed fixing plate 312 to pass through.

[0078] The driving system 317 is used to drive the slider 314 to move along the slide rail 313. In one embodiment, the driving system 317 is a servo motor system 3172 and a screw module system 3171, wherein the servo motor system 3172 and the screw module system 3171 are mature technologies and will not be described in detail in this application.

[0079] exist Figure 1 In the embodiment shown, the automatic wool strip threading and bending device further comprises a material receiving unit for collecting the selected profile 20 threaded with the wool strip 10 after being pressed. Accordingly, the second feeding assembly is used not only for moving the selected profile 20 threaded with the wool strip 10 to the position corresponding to the pressing assembly, but also for moving the selected profile 20 threaded with the wool strip 10 after being pressed to the top of the material receiving unit.

[0080] In this embodiment, the material receiving unit includes a material receiving box 41 and a slide 42. The material receiving box 41 is arranged behind the storage cabinet 12 and corresponds to the bottom of the slide 42. The slide 42 is arranged on the bracket and is used to receive the selected profile 20 with the wool strip 10 after being bent and slide the selected profile 20 with the wool strip 10 after being bent into the material receiving box 41. Specifically, Figure 3 and Figure 4 As shown, the slide 42 is arranged on one side of the first base 13 and the second base 14 near the rear of the workbench. If the first base 13 and the second base 14 of the U-shaped structure are divided into a vertical section and a horizontal section, the slide 42 is located on the vertical section near the rear of the workbench, the entrance of the slide 42 is located on the inner side of the vertical section (close to the other vertical section), and the exit of the slide 42 is located on the outer side of the vertical section (away from the other vertical section). The selected profile 20 with the wool strip 10 after bending slides into the entrance of the slide 42, rolls along the inclined slide to the exit of the slide 42 under the action of its own gravity, and then slides into the material receiving box 41 behind the workbench.

[0081] The second feeding assembly further includes a fourth sensor 315 and a fifth sensor 316. The fourth sensor 315 and the fifth sensor 316 are both arranged on the moving path of the feeding fixed plate 312. The fourth sensor 315 is used to detect whether the feeding fixed plate 312 has moved into position, and the fifth sensor 316 (also called an in-situ sensor) is used to detect whether the feeding fixed plate 312 has returned to its original position M (e.g., Figure 8 shown).

[0082] The present application also provides a control method for an automatic wool strip threading and bending device, comprising the following steps: controlling a positioning component to fix a selected profile; controlling a first feeding component to thread the wool strip into the selected profile; controlling a second feeding component to move the selected profile threaded with the wool strip to a position corresponding to a pressing component; and controlling the pressing component to press the selected profile threaded with the wool strip to form an arc.

[0083] The following describes in detail Figure 1 The steps of the control method of the automatic threading and bending device are as follows:

[0084] When the run button is clicked on the display control system 326, the device starts to automatically run the program. When the display control system 326 gives an action instruction to a moving component, the moving component performs a corresponding action according to the instruction.

[0085] Positioning process: the servo motor system 3171 drives the screw module system 3172 to return to the system starting point M and touches the fifth sensor 316. At this time, the second lifting mechanism (positioning upper and lower cylinders 311) drives the positioning cylinder 222 to rise into place. Then, the positioning cylinder 222 drives the first sub-clamp 2211 and the second sub-clamp 2212 to clamp the selected profile and align it with the wool strip inlet 141 to complete the positioning work.

[0086] Wool strip threading process: The rodless cylinder 212 drives the feeding pusher 211 to push the wool strip 10 at the bottom of the storage plate 2101 through the wool strip introduction port 141 and into the selected profile 20, thereby completing the automatic wool strip threading process. After the wool strip 10 is inserted into the selected profile 20, it touches the wool strip in place sensor 131. After the display control system 326 receives the wool strip in place signal, it controls the rodless cylinder 211 to drive the feeding pusher 211 to return to the origin. After returning to the origin, it touches the rodless cylinder in-situ sensor 2104. The wool strip slides to the bottom of the storage plate 2101 due to its own gravity and waits for the next push.

[0087] Feeding process: The second feeding assembly moves the selected profile with the wool strip to the position of the pressure assembly. Specifically, the driving system 317 drives the feeding fixed plate 312 to move along the slide rail 314 to move the selected profile 20 to the top of the lower mold block 3222. After that, the positioning cylinder 222 drives the clamp 221 to release the clamped selected profile, and then the positioning upper and lower cylinders 311 drive the positioning cylinder 222 and the clamp 221 to descend as a whole, placing the selected profile on the lower mold block to prepare for bending and shaping.

[0088] Bending process: The clamping cylinder 323 drives the upper mold 321 to press down to the position of the second sensor 324 and maintains the time set by the process. After the specified time is reached, the clamping cylinder 323 drives the upper mold 321 to rise and return to the origin.

[0089] Material collection process: The positioning cylinder 222 and the clamp 221 are driven by the positioning cylinder 311 to rise to the position of the selected profile. The clamp 221 clamps the selected profile 20, and the driving system 317 drives the feeding fixed plate 312 to move along the slide rail 314 until it touches the fourth sensor 315, and the driving system 317 stops driving. The positioning cylinder 222 drives the clamp 221 to release, and the positioning cylinder 222 and the clamp 221 are driven by the positioning cylinder 311 to drop as a whole, so that the selected profile 20 falls to the slideway 42, and finally the selected profile 20 falls into the storage box 41 due to its own gravity.

[0090] To sum up, the present application has the following advantages: the automatic wool threading and bending device of the present application not only improves the degree of automation of the wool threading and bending processes, saving working hours and labor costs, but also quantifies the processing indicators of the products, ensures the consistency of the products, and improves the overall quality of the products.
