Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner processing, in particular to a bending device. Background Art

[0002] Currently, the term "two-element" ("condenser") is used collectively to describe the condenser and evaporator in the refrigeration industry, and they are also key components of refrigeration equipment. Furthermore, bending the two-element components is a crucial process in air conditioning production. This involves bending the rectangular sheets of the two-element components into an L-shape according to preset parameters using bending equipment to facilitate subsequent processing steps.

[0003] However, in the actual production process, the diagonal dimensions of the two plates after bending are sometimes too large, which seriously affects the subsequent processing steps of the air conditioner and even affects the product quality of the finished air conditioner. Through long-term tracking and tracing, it is found that the main reasons include the following two parts:

[0004] Reason 1: The loading positioning of the two rectangular plates is inaccurate, and there is an error in the unloading posture. That is, the position of the two rectangular plates during bending is inaccurate, and they themselves may deflect and cannot be perpendicular to each other between the bending rollers. At this time, the bending lines of the two rectangular plates cannot be perpendicular to their length directions, and the diagonal dimensions of the two plates after bending will naturally be larger.

[0005] Reason 2: The dimensions of the incoming two-device plates are not compliant, that is, the width of the two-device plates is greater than the standard width (in fact, the long side and the short side of the two-device plates are not perpendicular). At this time, the diagonal dimensions of the two-device plates after bending will naturally be larger. Utility Model Content

[0044] In order to solve the problem of poor processing quality of two-device plates processed by bending equipment in the prior art, the present application provides a bending equipment.

[0045] like Figures 1 to 14As shown, the bending equipment includes a supporting structure 10, a bending device 20, a positioning structure 30 and a detection device 40. The supporting structure 10 is used to support the workpiece 1 to be processed. The bending device 20 is arranged on one side of the supporting structure 10. The bending device 20 includes a rotatable bending assembly 21. The bending assembly 21 includes at least two bending structures arranged opposite to each other. A clamping space 22 is formed between the at least two bending structures. The clamping space 22 is used to clamp the workpiece 1 to be processed. After the clamping space 22 clamps the workpiece 1 to be processed, the bending assembly 21 is rotated to bend the workpiece 1. The positioning structure 30 is arranged on the supporting structure 10. The positioning structure 30 is positioned along the first preset direction and / or the second preset direction by limiting the workpiece 1 to be processed. The detection device 40 is arranged on one side of the workpiece 1 to be processed to detect the diagonal dimension value of the workpiece 1 to be processed.

[0046] According to the technical solution of this embodiment, the bearing structure 10 of the bending equipment is used to carry the workpiece 1 to be processed, and the bending device 20 is arranged on one side of the bearing structure 10 and includes a rotatable bending component 21. The bending component 21 includes at least two relatively arranged bending structures, and a clamping space 22 is formed between the at least two bending structures. The clamping space 22 is used to clamp the workpiece 1 to be processed, so that after the workpiece 1 to be processed is clamped in the clamping space 22, the workpiece 1 to be processed is bent by rotating the bending component 21. The positioning structure 30 is arranged on the bearing structure 10. The positioning structure 30 positions the workpiece 1 to be processed along the first preset direction and / or the second preset direction by limiting the stop with the workpiece 1 to be processed. The detection device 40 is arranged on one side of the workpiece 1 to be processed, so as to detect the diagonal length value of the workpiece 1 to be processed. In this way, after the workpiece 1 to be processed is loaded onto the supporting structure, the positioning structure 30 can position the workpiece 1 along the first preset direction and the second preset direction, so as to improve the accuracy of the placement of the workpiece 1 to be processed and correct the posture of the workpiece 1 to be processed, ensuring that the extension direction of the workpiece 1 to be processed is perpendicular to the bending line formed after bending. At the same time, after the workpiece 1 to be processed is positioned, the detection device 40 can detect the diagonal dimension value of the workpiece 1 to be processed. By comparing the difference between the two diagonal dimension values, it can be determined whether the quality of the current workpiece 1 to be processed is qualified. In fact, the bending equipment in this embodiment can screen out unqualified workpieces 1 to be processed while ensuring that the workpiece 1 to be processed has a high positioning accuracy, thereby greatly improving the quality of the workpiece 1 to be processed after bending, thereby solving the problem of poor processing quality of the two-device plate processed by the bending equipment in the prior art and improving the product quality of the air conditioner.

[0047] In this embodiment, the workpiece 1 to be processed is a two-device plate (the two devices are an evaporator and a condenser).

[0048] In this embodiment, the workpiece 1 to be processed is a rectangular plate, the first preset direction is the length direction of the workpiece 1 to be processed, and the second preset direction is the width direction of the workpiece 1 to be processed.

[0049] In this embodiment, the detection device 40 is a laser sensor.

[0050] In this embodiment, the diagonal dimension value of the workpiece 1 to be processed includes the dimension values of its two diagonals. Specifically, since the two device plates are rectangular, the dimension values of their two diagonals should be equal. If the processing quality of the two device plates is unqualified (the long side and the short side are not perpendicular), there will be a deviation between the dimension values of the two diagonals.

[0051] Specifically, the deviation between the dimension values of the two diagonals should be less than or equal to two millimeters. If it is greater than two millimeters, it is judged that the processing quality of the two device plates is unqualified.

[0052] Optionally, there are multiple positioning structures 30, and the multiple positioning structures 30 include a first positioning structure 31 and a second positioning structure 32. The first positioning structure 31 has a first positioning surface 311 extending along a first preset direction, and the first positioning surface 311 is used to limit the stop with the workpiece 1 to be processed. The second positioning structure 32 has a second positioning surface 321 extending along a second preset direction, and the second positioning surface 321 is used to limit the stop with the workpiece 1 to be processed. The first preset direction and the second preset direction are arranged perpendicular to each other. In this way, the workpiece 1 to be processed is positioned simultaneously by the first positioning structure 31 and the second positioning structure 32, which can further ensure that the workpiece 1 to be processed has a high position accuracy. At the same time, the above-mentioned setting of the first positioning surface 311 and the second positioning surface 321 can match the structure of the workpiece 1 to be processed, while increasing the contact area between the positioning structure and the workpiece 1 to be processed to improve positioning reliability. At the same time, the posture of the workpiece 1 to be processed can be corrected during the positioning process to further improve the bending processing quality of the subsequent bending step.

[0053] Specifically, since the first positioning surface 311 and the second positioning surface 321 are perpendicular to each other, the first positioning surface 311 and the second positioning surface 321 can respectively make close contact with the two adjacent side surfaces of the two device plates, so as to correct the self-deflection angles of the two device plates to a preset angle while performing reliable positioning.

[0054] Optionally, at least two first positioning structures 31 are movably arranged along a second preset direction, and the first positioning surfaces 311 of the at least two first positioning structures 31 are arranged relative to each other and surround each other to form a positioning space, with at least a portion of the workpiece 1 being positioned within the positioning space. The bending machine further comprises a first drive device 50, which is drivably connected to at least one of the first positioning structures 31. The first drive device 50 drives the first positioning structure 31 toward or away from at least another first positioning structure 31 to adjust the size of the positioning space. In this way, the first positioning structure 31 can not only position the workpiece 1 by clamping, but also initially secure the workpiece 1 to prevent the workpiece 1 from shaking or shifting during the subsequent bending process, thereby affecting the bending quality of the workpiece 1. At the same time, by driving the first positioning structure 31 to move, the first drive device 50 not only achieves the automated operation of the first positioning structure 31 and improves the automation level of the bending machine, but also enables the size of the positioning space to be adjusted to accommodate workpieces 1 of different specifications and sizes, thereby improving the positioning versatility of the first positioning structure 31.

[0055] In this embodiment, the first positioning structure 31 is movably provided along the width direction of the workpiece 1 to be processed.

[0056] In this embodiment, there are two first positioning structures 31 , and a positioning space is formed between the first positioning surfaces 311 of the two first positioning structures 31 .

[0057] It should be noted that the number of the first positioning structures 31 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of the first positioning structures 31 is four, six, eight, or ten.

[0058] In this embodiment, there are two first driving devices 50 , and the two first driving devices 50 are disposed in a one-to-one correspondence with the two first positioning structures 31 .

[0059] Optionally, the first driving device 50 is a servo motor or a driving cylinder.

[0060] In this embodiment, the first positioning structure 31 is plate-shaped, and the side surface of the first positioning structure 31 facing the other first positioning structure 31 is a first positioning surface 311 .

[0061] Optionally, the bending apparatus further includes a control module connected to the first drive device 50, and configured to control at least one of the rotational speed and rotational direction of the first drive device 50 according to preset values. Thus, by controlling the operating state of the first drive device 50 through the control module, it is possible to prevent the first positioning structure 31 from moving too far, thereby preventing the workpiece 1 from being damaged by clamping, and to prevent the first positioning structure 31 from moving too far, thereby preventing the workpiece 1 from being accurately positioned.

[0062] Specifically, the preset value is the size information of the workpiece 1 to be processed.

[0063] Specifically, the control module controls the speed and direction of the first drive device 50. By controlling the speed of the first drive device 50, the start and stop of the first drive device 50 can be achieved (that is, the speed of the first drive device 50 is controlled to 0 to achieve the stop of the first drive device 50). By controlling the direction of the first drive device 50, the movement direction of the first positioning structure 31 can be controlled.

[0064] like Figure 1 、 Figure 2 and Figures 6 to 9 As shown, the second positioning structure 32 includes a positioning portion 322 and a mounting portion 323, and the positioning portion 322 has a second positioning surface 321. The mounting portion 323 is movably arranged on the supporting structure 10 along the second preset direction, and the positioning portion 322 is arranged on the mounting portion 323 and moves synchronously with the mounting portion 323. Among them, the detection device 40 is arranged on the positioning portion 322, and the positioning portion 322 is arranged to be raised and lowered so as to adjust the height of the detection device 40 when the positioning portion 322 drives the detection device 40 to move up and down. In this way, the above-mentioned arrangement can, on the one hand, drive the positioning portion 322 to move through the mounting portion 323 to realize the positioning action of the positioning portion 322; on the other hand, the positioning portion 322 can drive the detection device 40 to move up and down to adjust the detection height of the detection device 40, thereby adapting to workpieces 1 to be processed of different specifications and sizes, which not only improves the detection accuracy of the detection device 40, but also improves the detection versatility of the detection device 40.

[0065] It should be noted that when the mounting portion 323 drives the positioning portion 322 to move to the limit stop with the workpiece 1 to be processed, the mounting portion 323 can continue to drive the positioning portion 322 to move to push the workpiece 1 to move, thereby adjusting the position of the workpiece 1 to be processed.

[0066] In this embodiment, the positioning portion 322 includes a rod-shaped positioning member 3221 and a plate-shaped mounting member 3222. The side of the rod-shaped positioning member 3221 facing the workpiece 1 to be processed is a second positioning surface 321. The plate-shaped mounting member 3222 is arranged on the rod-shaped positioning member 3221. The detection device 40 is arranged on the plate-shaped mounting member 3222 and is located on the side of the rod-shaped positioning member 3221 away from the workpiece 1 to be processed.

[0067] In this embodiment, a detection hole for avoiding the detection end of the detection device 40 is further provided on the rod-shaped positioning member 3221 .

[0068] like Figure 1 、 Figure 2 and Figures 6 to 9 As shown, the supporting structure 10 includes a mounting member 11 and a supporting member 12. The supporting member 12 is spaced apart from the mounting member 11. The supporting member 12 is used to support the workpiece 1 to be processed and has an avoidance hole 121. The mounting portion 323 is movably mounted on the supporting member 12, with at least a portion of the mounting portion 323 extending through the avoidance hole 121. The positioning portion 322 is liftably mounted on this portion of the mounting portion 323. The bending equipment further includes a second drive device 60 and a third drive device 70. The second drive device 60 is mounted on the mounting portion 323 and moves synchronously with the mounting portion 323. The second drive device 60 is drivably connected to the positioning portion 322 to drive the positioning portion 322 to move upward and downward. The third drive device 70 is disposed between the supporting member 12 and the mounting member 11 and drivably connected to the mounting portion 323 to drive the mounting portion 323 to move the positioning portion 322. In this way, the above-mentioned arrangement can, on the one hand, realize the simultaneous positioning action and lifting action (i.e., height adjustment of the detection device 40) of the positioning portion 322, so as to improve the working efficiency of the bending equipment; on the other hand, it makes it unnecessary for the third driving device 70 to be arranged on the carrier 12, which not only reduces the size of the carrier 12, but also makes the structural position relationship between the carrier structure 10, the mounting portion 323, the positioning portion 322 and the third driving device 70 more compact and reasonable, avoids interference between the various components, and realizes the miniaturization design of the carrier structure 10.

[0069] In this embodiment, a support member 13 is further provided between the mounting member 11 and the bearing member 12 , and the support member 13 is used to support the bearing member 12 .

[0070] In this embodiment, both the mounting member 11 and the supporting member 12 are plate-shaped.

[0071] In this embodiment, the mounting portion 323 includes a bracket 3231 and a mounting plate 3232 . The bracket 3231 is inserted into the avoidance hole 121 , and the mounting plate 3232 is disposed on the bracket 3231 for mounting the second driving device 60 .

[0072] In this embodiment, a guide rail slider mechanism 72 is also provided on the mounting member 11. The third driving device 70 is connected to the slider drive of the guide rail slider mechanism 72 through the third reducer 71. A second connecting seat 80 is provided on the slider, and the bracket 3231 is provided on the second connecting seat 80. The third driving device 70 drives the slider to move along the guide rail extension direction of the guide rail slider mechanism 72 to drive the second connecting seat 80 and the bracket 3231 provided on the slider to move.

[0073] In this embodiment, a second reducer 61 is also provided between the second driving device 60 and the mounting plate 3232. The second driving device 60 is connected to one end of the second reducer 61. The other end of the second reducer 61 is connected to a connecting rod. The connecting rod is driven and connected to the rod-shaped positioning member 3221 through the first connecting seat 324 to drive the rod-shaped positioning member 3221 to perform lifting and lowering movements.

[0074] In this embodiment, the first connecting seat 324 includes a photosensitive connecting plate 3242 and a guide beam 3241 arranged on the photosensitive connecting plate 3242. A guide rail slider assembly 325 is arranged between the guide beam 3241 and the bracket 3231. The guide rail slider assembly 325 is used to guide the lifting and lowering movement direction of the first connecting seat 324. The rod-shaped positioning member 3221 is connected to the connecting rod through the photosensitive connecting plate 3242.

[0075] like Figures 1 to 5 As shown, the bending device 20 also includes a mounting base 23 and a drive structure 24. The bending assembly 21 is rotatably mounted on the mounting base 23. The drive structure 24 is connected to the bending assembly 21 via a transmission assembly 25 to drive the bending assembly 21 to rotate. Thus, the mounting base 23 effectively provides a fixed support point for the drive structure 24 and the bending assembly 21, ensuring that the drive structure 24 can stably drive the bending assembly 21 to rotate via the transmission assembly 25.

[0076] In this embodiment, the mounting seat 23 is a bearing seat.

[0077] In this embodiment, a first reducer 241 is further provided on the mounting seat 23 , the driving structure 24 is drivingly connected to one end of the first reducer 241 through a coupling, and the other end of the first reducer 241 is drivingly connected to the bending assembly 21 through the transmission assembly 25 .

[0078] like Figures 1 to 5As shown, the transmission assembly 25 includes a connecting shaft 251 and a connecting member 252 disposed on the connecting shaft 251. The connecting member 252 rotates synchronously with the connecting shaft 251. The driving structure 24 is drivingly connected to the connecting shaft 251. The at least two bending structures include a first bending structure 211 and a second bending structure 212. The first bending structure 211 is roller-shaped and drivingly connected to the connecting shaft 251. The second bending structure 212 is disposed on the connecting member 252 and includes a plate-shaped bending portion 2121. The plate-shaped bending portion 2121 and the first bending structure 211 form a clamping space 22. The plate-shaped bending portion 2121 is movably disposed so that the size of the clamping space 22 can be adjusted when the distance between the plate-shaped bending portion 2121 and the first bending structure 211 changes. In this way, the plate-shaped bending portion 2121 and the first bending structure 211 can clamp and bend workpieces 1 of different specifications and sizes, thereby improving the versatility of the bending device 20. At the same time, the above-mentioned arrangement of the transmission assembly 25 enables the first bending structure 211 and the second bending structure 212 to rotate synchronously, thereby improving the bending reliability of the bending device 20.

[0079] In this embodiment, the connecting member 252 is a crank, and the connecting shaft 251 is a crank shaft.

[0080] like Figures 1 to 5 As shown, the second bending structure 212 also includes a mounting body 2122 and a fourth drive device 2123, and the mounting body 2122 is arranged on the connecting member 252. The fourth drive device 2123 is arranged on the mounting body 2122, and the fourth drive device 2123 is driven and connected to the plate-shaped bending portion 2121, so as to drive the plate-shaped bending portion 2121 to move closer to or away from the first bending structure 211. In this way, the fourth drive device 2123 arranged on the mounting body 2122 can drive the plate-shaped bending portion 2121 to move closer to or away from the first bending structure 211 while rotating synchronously with the mounting body 2122, so as to achieve the synchronization of the bending action and the clamping action. At the same time, the above arrangement also makes the structure for realizing the driving connection between the fourth drive device 2123 and the plate-shaped bending portion 2121 simpler, easier to process and implement, thereby reducing the processing cost of the bending device 20.

[0081] In this embodiment, the installation body 2122 is formed by connecting a plurality of plate-like structures, and its specific structure is not described in detail.

[0082] In this embodiment, the bending device also includes a guide rod slide assembly 27, the guide rod of the guide rod slide assembly 27 is arranged on the plate-shaped bending portion 2121, the guide rod slide assembly 27 is arranged on the mounting body 2122, and the guide rod can be slidably passed through the slide to guide the movement direction of the plate-shaped bending portion 2121 during its movement.

[0083] Optionally, the fourth driving device 2123 is a driving cylinder.

[0084] like Figures 1 to 5 As shown, the plate-shaped bending portion 2121 is provided with a strip-shaped hole 2121a. The first positioning structure 31 is movably disposed on the plate surface of the plate-shaped bending portion 2121 facing the first bending structure 211. The first driving device 50 for driving the first positioning structure 31 is disposed on the plate surface of the plate-shaped bending portion 2121 away from the second bending structure 212. The bending device further includes a connecting assembly 26, at least a portion of which is located within the strip-shaped hole 2121a. The first driving device 50 is drivingly connected to the first positioning structure 31 via the connecting assembly 26. In this way, the above-mentioned arrangement enables the first driving device 50 and the first positioning structure 31 to be respectively located on both sides of the plate-like bending portion 2121 (that is, the first driving device 50 does not need to be arranged on the plate surface of the plate-like bending portion 2121 facing the first bending structure 211), so as to reduce the size of the plate-like bending portion 2121 and realize the miniaturization design of the bending device 20; on the other hand, the above-mentioned arrangement of the strip hole 2121a and the connecting component 26 ensures that the first driving device 50 can be driven and connected to the first positioning structure 31, thereby driving the first positioning structure 31 to move.

[0085] In this embodiment, the connecting component 26 is a guide module.

[0086] Specifically, the slider structure of the guide module is inserted into the strip hole 2121 a and connected to the first positioning structure 31 to drive the first positioning structure 31 to move.

[0087] In this embodiment, the first driving device 50 is a servo motor.

[0088] In this embodiment, the bending equipment is actually placed on the air conditioner production line, and its operation process is as follows:

[0089] Before starting processing, the staff needs to input the size information of the workpiece 1 to be processed into the control module. After processing starts, the loading robot on the air conditioner production line loads the workpiece 1 to be processed onto the supporting structure 10. The control module controls the movement of the driving structure 24 according to the preset value (size information) input by the staff to adjust the size of the positioning space and perform preliminary positioning of the workpiece 1 in the width direction of the workpiece 1. After preliminary positioning, the control module controls the operation of the second driving device 60 according to the preset value (size information) to drive the detection device 40 to rise and fall to the appropriate position, thereby detecting the diagonal size value of the workpiece 1 to be processed. The control module determines whether the quality of the current workpiece 1 to be processed is qualified based on the detected value.

[0090] If the quality of the current workpiece 1 is qualified, the second driving device 60 and the third driving device 70 are controlled to operate simultaneously to adjust the second positioning surface 321 to a suitable height, and at the same time drive the positioning portion 322 to move toward the workpiece 1 until the second positioning surface 321 and the workpiece 1 are stopped and the workpiece 1 is pushed to a suitable position for secondary positioning. After the secondary positioning, the control module controls the bending device 20 to clamp the workpiece 1 and perform bending processing. After the bending processing, the control module controls the first positioning structure 31 and the positioning portion 322 to move away from the workpiece 1, and the loading robot simultaneously unloads and reloads the material to re-perform preliminary positioning and testing;

[0091] If the quality of the current workpiece 1 is unqualified, the control module controls the first positioning structure 31 to move away from the workpiece 1, and the loading robot simultaneously unloads and reloads the workpiece to perform preliminary positioning and inspection again.

[0092] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0093] The bearing structure of the bending equipment is used to bear the workpiece to be processed. The bending device is arranged on one side of the bearing structure and includes a rotatable bending assembly. The bending assembly includes at least two bending structures arranged opposite to each other. A clamping space is formed between the at least two bending structures. The clamping space is used to clamp the workpiece to be processed. After the workpiece to be processed is clamped in the clamping space, the workpiece to be processed is rotated by the bending assembly to be bent. The positioning structure is arranged on the bearing structure. The positioning structure positions the workpiece to be processed along a first preset direction and / or a second preset direction by limiting the stop with the workpiece to be processed. The detection device is arranged on one side of the workpiece to be processed to detect the diagonal size value of the workpiece to be processed. In this way, when the workpiece to be processed is loaded onto the bearing structure, the positioning structure can position the workpiece to be processed along the first preset direction and the second preset direction, so as to improve the accuracy of the placement of the workpiece to be processed and correct the posture of the workpiece to be processed to ensure that the extension direction of the workpiece to be processed is perpendicular to the bending line formed after bending. At the same time, after the workpiece to be processed is positioned, the detection device can detect the diagonal dimension value of the workpiece to be processed. By comparing the difference between the two diagonal dimension values, it can be judged whether the quality of the current workpiece to be processed is qualified. In fact, the bending equipment in this application can ensure that the workpiece to be processed has a high positioning accuracy while screening out unqualified workpieces to be processed, greatly improving the quality of the workpiece to be processed after bending, thereby solving the problem of poor processing quality of the two-device plate processed by the bending equipment in the prior art, and improving the product quality of the air conditioner.
