Description

Technical Field

[0001] The present invention relates to the field of intelligent manufacturing technology, and in particular to a position correction device and an axial flow fan blade assembly line. Background Art

[0002] In an automated production line, the device to be processed needs to be calibrated before processing. Taking the assembly of axial flow fan blades as an example, the axial flow fan blades are usually assembled on the motor bracket through the motor. Before assembling the axial flow fan blades, the position of the motor bracket needs to be calibrated.

[0003] However, the motor bracket itself is overlapped on the condenser component. Affected by the condenser component, the motor bracket tilts forward and backward and deflects left and right, resulting in that after correction, the position consistency of the motor bracket is difficult to ensure. Summary of the invention

[0004] In view of this, the present invention provides a position correction device and an axial flow fan blade assembly line to solve the problem in the prior art that the position consistency of the motor bracket is difficult to ensure.

[0005] In a first aspect, the present invention provides a position correction device, comprising:

[0006] Scaffolding;

[0007] A pressing mechanism, connected to the base frame, capable of descending and pressing the workpiece;

[0008] The first clamping mechanism and the second clamping mechanism are capable of opening and closing along the horizontal direction and clamping the workpiece, and an angle is formed between the opening and closing direction of the first clamping mechanism and the opening and closing direction of the second clamping mechanism;

[0009] The driving mechanism is connected to the base frame and can drive the base frame to move.

[0010] Beneficial effects: During the use of the position correction device of the present invention, the driving mechanism can drive the base frame to the target position, and then the pressing mechanism can descend and press the motor bracket, thereby ensuring that the top of the motor bracket does not warp, avoiding the motor bracket from tilting forward and backward, or tilting left and right, and avoiding the inclination of the motor bracket affecting the consistency of the position of the motor bracket after correction. Then the first clamping mechanism and the second clamping mechanism can limit the motor bracket from the x direction and the y direction respectively, thereby completing the correction of the motor bracket, and the consistency of the motor bracket after correction is good.

[0011] In addition, the position correction device of the embodiment of the present application can correct the motor bracket from both sides and the top, thereby avoiding the situation where the position correction device is difficult to extend between the motor bracket and the condenser when the size of the shell is small. The position correction device of the embodiment of the present application can be used to perform position correction on smaller air-conditioning outdoor units and has a wide range of applications.

[0015] Beneficial effect: Through such an arrangement, the second section of the first clamping member can be used to reduce the distance between the two first clamping members, thereby ensuring that the first clamping member can clamp and limit both sides of the motor bracket along the x-direction without moving a large stroke, and can increase the interference after clamping.

[0016] In an optional embodiment, the first clamping mechanism includes:

[0017] The first centering cylinder is arranged at the bottom of the base frame, the first clamping member is connected to the first centering cylinder, and the two first clamping members can perform opening and closing movements under the action of the first centering cylinder.

[0018] Beneficial effect: The two first clamping members are driven to open and close by the first centering cylinder, which helps to improve the accuracy of the first clamping mechanism in positioning the motor bracket.

[0019] In an optional embodiment, the second clamping mechanism includes a pair of second clamping members arranged opposite to each other, and each second clamping member includes:

[0020] The third section extends downward;

[0021] The fourth section is connected to the third section and is arranged on a side of the third section away from the other second clamping member.

[0022] Beneficial effect: The third section and the fourth section can together form a Z-shaped second clamping member, thereby increasing the distance between the fourth sections of the two second clamping members, so that the distance between the two second clamping members can be greater than the width of the rear hook of the motor bracket along the x-direction, so that the movement range of the second clamping mechanism avoids the upward tilt of the motor bracket hook, thereby effectively avoiding the second clamping mechanism from interfering with the rear hook of the motor bracket during movement.

[0023] In an optional embodiment, a limiting plug block is formed at the bottom end of the fourth section.

[0024] Beneficial effect: The limiting plug can be inserted into the matching hole at the top of the hook, thereby clamping the top of the hook and limiting the hook, without having to extend it completely between the hook and the condenser, thereby avoiding the difficulty of the second clamping member to penetrate into the motor bracket and the condenser when the size of the whole machine is small, thereby reducing the scope of application of the position correction device. The position correction device of the embodiment of the present application can be used to correct the size of the motor bracket of the 0.75p air conditioner outdoor unit, and has a wide range of applications.

[0025] In an optional embodiment, the second clamping mechanism includes:

[0026] The second centering cylinder is arranged at the bottom of the base frame, the second clamping piece is connected to the second centering cylinder, and the two second clamping pieces can perform opening and closing movements under the action of the second centering cylinder.

[0027] Beneficial effect: The second centering cylinder drives the two second clamping members to perform opening and closing movements, which helps to improve the accuracy of the second clamping mechanism in positioning the motor bracket.

[0029] a first transverse module;

[0030] A second transverse module is connected to a power output end of the first transverse module, and the first transverse module can drive the second transverse module to move along a first direction;

[0031] The vertical module is connected to the power output end of the second horizontal module. The second horizontal module can drive the vertical module to move along the second direction. The base frame is connected to the power output end of the vertical module.

[0032] Beneficial effect: Through such an arrangement, the first horizontal module and the second horizontal module can cooperate with each other and drive the base to move in the horizontal plane, the vertical module can lift the base, and the driving mechanism can drive the base to move within a spatial range, thereby accurately moving to the position corresponding to the motor bracket to be processed, and performing precise position correction on the motor bracket to be processed.

[0033] In a second aspect, the present invention further provides an axial flow fan blade assembly line, comprising:

[0034] The position correction device of the first aspect of the present invention;

[0035] The conveying mechanism is arranged below the position correction device.

[0036] Beneficial effects: The axial flow fan blade assembly line of the second aspect of the present invention includes or uses the axial flow fan of the first aspect of the present invention, and thus has its beneficial effects, namely, it can ensure that the top of the motor bracket does not warp, avoid the motor bracket from tilting forward and backward, or tilting left and right, and avoid affecting the consistency of the position of the motor bracket after correction due to the tilt of the motor bracket. Then the first clamping mechanism and the second clamping mechanism can limit the motor bracket from the x direction and the y direction respectively, thereby completing the correction of the motor bracket, and the consistency of the motor bracket after correction is good.

[0039] Beneficial effect: Through such an arrangement, when the motor bracket to be processed moves to the target workstation on the conveying mechanism, the lifting mechanism can lift the motor bracket to be processed, thereby separating the motor bracket to be processed from the driving mechanism, and can limit the position of the motor to be processed, and avoid the vibration generated during the transmission process of the conveying mechanism causing the motor bracket to vibrate, thereby affecting the accuracy of position correction.

[0040] In an optional embodiment, the conveying mechanism is further provided with a bearing member, which is arranged on the conveyor belt and is used to carry the motor bracket to be processed. The lifting mechanism includes:

[0044] Beneficial effect: When the motor bracket to be processed reaches the target workstation, the lifting cylinder can extend and drive the lifting plate to carry the lifting pin to move upward. The lifting pin can be inserted into the limiting hole on the bearing component, thereby limiting the motor bracket while lifting the motor bracket. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0080] The air conditioner outdoor unit and the air cooler include a housing 7, a condenser 6, a motor bracket 5, a motor and an axial flow fan blade. The condenser 6 is arranged in the housing 7, the motor bracket 5 is connected to the condenser 6 through a hook 501, the motor is mounted on the motor bracket 5, and the axial flow fan blade is mounted on the output shaft of the motor.

[0081] Taking the installation process of the axial flow fan blades of the air conditioner outdoor unit as an example, in order to realize the automatic assembly of the axial flow fan blades, it is necessary to use the position correction device 1 to correct the position of the fan bracket to ensure the consistency of the motor bracket 5. The whole machine has a variety of different models, such as 0.75P, 1P and 1.5P (where P stands for "horsepower", referring to the power consumption of the air conditioner), which requires the position correction device 1 to be compatible with models of different sizes.

[0082] In the related art, the position correction device 1 usually needs to extend between the motor bracket 5 and the condenser 6 to clamp and correct the motor bracket 5. However, for a smaller model, such as a 0.75P air conditioner outdoor unit, it is difficult for the position correction device 1 to extend between the motor bracket 5 and the condenser 6. Exemplarily, when the air conditioner is 1P or 1.5P, the distance between the condenser 6 and the motor bracket 5 is about 60mm.

[0083] When the air conditioner outdoor unit is 0.75P, the distance between the condenser 6 and the motor bracket 5 is only about 4 mm, and the position correction device 1 is difficult to extend between the motor bracket 5 and the condenser 6, so the position correction of the motor bracket 5 cannot be achieved.

[0084] Since the rear side of the motor bracket 5 will overlap with the sponge of the condenser 6, the sponge may easily stick and warp, causing the rear hook 501 of the motor bracket 5 to warp up, resulting in interference between the position correction device 1 and the hook 501 of the motor bracket 5.

[0085] Combine the following Figures 1 to 18 , describing an embodiment of the present invention.

[0086] According to an embodiment of the present invention, on the one hand, a position correction device 1 is provided. Figure 6 , Figure 7 and Figure 8 As shown, it includes a base frame 101, a pressing mechanism 102, a first clamping mechanism 103, a second clamping mechanism 104 and a driving mechanism 105.

[0087] The pressing mechanism 102 is connected to the base frame 101 and can be lowered to press the workpiece. The first clamping mechanism 103 and the second clamping mechanism 104 can open and close in the horizontal direction and clamp the workpiece. An angle is formed between the opening and closing direction of the first clamping mechanism 103 and the opening and closing direction of the second clamping mechanism 104. The driving mechanism 105 is connected to the base frame 101 and can drive the base frame 101 to move.

[0088] For the convenience of description below, the opening and closing direction of the first clamping mechanism 103 is defined as the x-direction, and the opening and closing direction of the second clamping mechanism 104 is defined as the y-direction.

[0089] It should be noted that, in the real-time example of the present application, the angle between the x direction and the y direction is not limited. For example, in a preferred embodiment, the x direction and the y direction are perpendicular to each other.

[0090] During use of the position correction device 1 of the present invention, the driving mechanism 105 can drive the base frame 101 to the target position, and then the pressing mechanism 102 can descend and press the motor bracket 5, thereby ensuring that the top of the motor bracket 5 does not warp, avoiding the motor bracket 5 from tilting forward and backward, or tilting left and right, and avoiding the inclination of the motor bracket 5 affecting the consistency of the position of the corrected motor bracket 5. Then the first clamping mechanism 103 and the second clamping mechanism 104 can limit the motor bracket 5 from the x direction and the y direction respectively, thereby completing the correction of the motor bracket 5, and the consistency of the motor bracket 5 after correction is good.

[0091] In addition, the position correction device 1 of the embodiment of the present application can correct the motor bracket 5 from both sides and the top, thereby avoiding the situation where the position correction device 1 is difficult to extend between the motor bracket 5 and the condenser 6 when the size of the shell 7 is small. The position correction device 1 of the embodiment of the present application can be used to perform position correction on smaller air-conditioning outdoor units and has a wide range of applications.

[0092] In one embodiment, the pressing mechanism 102 is disposed on one side of the first clamping mechanism 103 and the second clamping mechanism 104 along the y direction, which can prevent the pressing mechanism 102 from deflecting the motor bracket 5 and will not interfere with the first clamping mechanism 103 and the second clamping mechanism 104.

[0093] In one embodiment, Figure 1 As shown, the pressing mechanism 102 is an elastic pressing mechanism, including a linear bearing, a telescopic rod and a spring. The linear bearing is arranged on the base 201, and the telescopic rod is inserted into the linear bearing. A protruding pressing portion is provided at the bottom end of the telescopic rod, and the spring is sleeved outside the telescopic rod and supported between the linear bearing and the pressing portion.

[0094] In one embodiment, Figure 6 As shown, the first clamping mechanism 103 includes a pair of first clamping members 1032 arranged opposite to each other, and each first clamping member 1032 includes a first section 10321 and a second section 10322 .

[0095] The first section 10321 extends downward. The second section 10322 is connected to the lower portion of the first section 10321 and extends toward a direction approaching another first clamping member 1032 .

[0096] By such a configuration, the second section 10322 of the first clamping member 1032 can be used to reduce the distance between the two first clamping members 1032, thereby ensuring that the first clamping member 1032 can clamp and limit the motor bracket 5 on both sides along the x-direction without moving a large stroke, and can increase the interference after clamping.

[0097] As a convertible implementation, in an embodiment not shown in the drawings, the opposite surfaces of the two first clamping members 1032 both extend in the vertical direction.

[0098] In one embodiment, the first clamping mechanism 103 includes a first centering cylinder 1031. The first centering cylinder 1031 is disposed at the bottom of the base frame 101, and the first clamping member 1032 is connected to the first centering cylinder 1031. The two first clamping members 1032 can perform opening and closing movements under the action of the first centering cylinder 1031.

[0099] The first centering cylinder 1031 drives the two first clamping members 1032 to perform opening and closing movements, which helps to improve the accuracy of the first clamping mechanism 103 in positioning the motor bracket 5 .

[0100] As a convertible implementation, in an embodiment not shown in the drawings, the first clamping mechanism 103 can also be an electric clamp.

[0101] As another alternative implementation, the two first clamping members 1032 may also be driven by a servo motor.

[0102] In one embodiment, the second clamping mechanism 104 is disposed between the two first clamping members 1032 .

[0103] By setting the second clamping member 1042 in the middle position of the first clamping mechanism 103 in this way, the structure of the position correction device 1 can be made simpler and more compact while the movements of the first clamping mechanism 103 and the second clamping mechanism 104 do not interfere with each other.

[0104] In one embodiment, Figure 6As shown, the second clamping mechanism 104 includes a pair of second clamping members 1042 disposed opposite to each other. Each second clamping member 1042 includes a third section 10421 and a fourth section 10422.

[0105] The third section 10421 extends downward. The fourth section 10422 is connected to the third section 10421 , and the fourth section 10422 is disposed on a side of the third section 10421 away from the other second clamping member 1042 .

[0106] The third section 10421 and the fourth section 10422 can together form a Z-shaped second clamping member 1042, thereby increasing the distance between the fourth sections 10422 of the two second clamping members 1042, so that the distance between the two second clamping members 1042 can be greater than the width of the rear hook 501 of the motor bracket 5 along the x-direction, so that the movement range of the second clamping mechanism 104 avoids the upward tilting of the hook 501 of the motor bracket 5, thereby effectively avoiding the second clamping mechanism 104 from interfering with the rear hook 501 of the motor bracket 5 during movement.

[0107] As a convertible implementation, in an embodiment not shown in the drawings, the third section 10421 and the fourth section 10422 can together form a 7-shaped second clamping member 1042 .

[0108] In one embodiment, the second clamping member 1042 includes a second centering cylinder 1041. The second centering cylinder 1041 is disposed at the bottom of the base frame 101. The second clamping member 1042 is connected to the second centering cylinder 1041, and the two second clamping members 1042 can perform opening and closing movements under the action of the second centering cylinder 1041.

[0109] The second centering cylinder 1041 drives the two second clamping members 1042 to perform opening and closing movements, which helps to improve the accuracy of the second clamping mechanism 104 in positioning the motor bracket 5 .

[0110] As a convertible implementation, in an embodiment not shown in the drawings, the second clamping mechanism 104 can also be an electric clamp.

[0111] As another alternative embodiment, the two second clamping members 1042 may also be driven by a servo motor.

[0112] In one embodiment, Fig.13 and Fig.14 As shown, the bottom end of the fourth section 10422 forms a limited position plug block.

[0113] The limiting plug can be inserted into the matching hole 5011 at the top of the hook 501, so as to clamp the top of the hook 501 and limit the hook 501, without having to fully extend between the hook 501 and the condenser 6, thereby avoiding the difficulty of the second clamping member 1042 to penetrate into the motor bracket 5 and the condenser 6 when the size of the whole machine is small, thereby reducing the applicable scope of the position correction device 1. The position correction device 1 of the embodiment of the present application can be used to correct the size of the motor bracket 5 of the air conditioner outdoor unit of 0.75p, and has a wide range of applications.

[0114] In one embodiment, the driving mechanism 105 includes a first transverse module 1051 , a second transverse module 1052 and a vertical module 1053 .

[0115] The second transverse module 1052 is connected to the power output end of the first transverse module 1051, and the first transverse module 1051 can drive the vertical module 1053 to move along the first direction. The vertical module 1053 is connected to the power output end of the second transverse module 1052, and the second transverse module 1052 can drive the vertical module 1053 to move along the second direction. The base frame 101 is connected to the power output end of the vertical module 1053.

[0116] Through such an arrangement, the first horizontal module 1051 and the second horizontal module 1052 can cooperate with each other and drive the base 201 to move in the horizontal plane, the vertical module 1053 can lift the base 201, and the driving mechanism 105 can drive the base 201 to move within a spatial range, thereby accurately moving to the position corresponding to the motor bracket 5 to be processed, and performing precise position correction on the motor bracket 5 to be processed.

[0117] As a convertible implementation, the driving mechanism 105 may also be a robotic arm.

[0118] In one embodiment, the position correction device 1 further includes a support frame 106 , and the driving mechanism 105 is disposed on the support frame 106 .

[0119] According to an embodiment of the present invention, on the other hand, an axial flow fan blade assembly line is provided, comprising the position correction device 1 provided in the first aspect of the present invention and a conveying mechanism 2. The conveying mechanism 2 is arranged below the position correction device 1.

[0120] The axial flow fan blade assembly line of the second aspect of the present invention includes or uses the axial flow fan of the first aspect of the present invention, and thus has its beneficial effects, namely, it can ensure that the top of the motor bracket 5 does not warp, avoid the motor bracket 5 from tilting forward and backward, or tilting left and right, and avoid affecting the consistency of the position of the motor bracket 5 after correction due to the tilt of the motor bracket 5. Then the first clamping mechanism 103 and the second clamping mechanism 104 can limit the motor bracket 5 from the x direction and the y direction respectively, thereby completing the correction of the motor bracket 5, and the consistency of the motor bracket 5 after correction is good.

[0121] In one embodiment, Fig.16 and then Fig.18 As shown, the conveying mechanism 2 includes a base 201 and a conveyor belt 202. The conveyor belt 202 is arranged on the base 201 and can move along the length direction of the base 201. The axial flow fan blade assembly line also includes a lifting mechanism 3. The lifting mechanism 3 is arranged on the base 201 and is spaced apart from the conveyor belt 202, and is used to lift the motor bracket 5.

[0122] Through such an arrangement, when the motor bracket 5 to be processed moves to the target workstation on the conveying mechanism 2, the lifting mechanism 3 can lift the motor bracket 5 to be processed, thereby separating the motor bracket 5 to be processed from the driving mechanism 105, and can limit the position of the motor to be processed, and avoid the vibration of the conveying mechanism 2 causing the motor bracket 5 to vibrate, thereby affecting the accuracy of the position correction.

[0123] As a convertible embodiment, the conveying mechanism 2 can also be configured to stop moving when the motor bracket 5 to be processed moves to the target workstation, so that the position correction device 1 can correct the position of the motor bracket 5 at the target workstation.

[0124] In one embodiment, Fig.15 As shown, the conveying mechanism 2 is also provided with a bearing member 4, which is arranged on the conveyor belt 202 and is used to carry the motor bracket 5 to be processed. The lifting mechanism 3 includes a lifting cylinder 301, a lifting plate 302 and a lifting pin 303.

[0125] The lifting cylinder 301 is connected to the base 201. The lifting plate 302 is connected to the power output end of the lifting cylinder 301 and can be lifted and lowered under the drive of the lifting cylinder 301. The lifting pin 303 is arranged on the lifting plate 302, and the bearing member 4 is provided with a limiting hole 401 capable of accommodating the lifting pin 303.

[0126] When the motor bracket 5 to be processed reaches the target workstation, the lifting cylinder 301 can extend and drive the lifting plate 302 to carry the lifting pin 303 to move upward, and the lifting pin 303 can be inserted into the limiting hole 401 on the carrier 4, thereby limiting the motor bracket 5 while lifting the motor bracket 5.

[0127] In one embodiment, a positioning pin 402 is provided on the carrier 4, and the positioning pin 402 can be inserted into the positioning hole 701 on the motor bracket 5, so as to fix the motor bracket 5 on the carrier 4 and effectively prevent the motor bracket 5 from moving forward and backward or left and right.

[0128] The carrier 4 is preferably but not limited to a process plate.

[0129] Next, the use process of the axial flow fan blade assembly line according to the embodiment of the present invention is described:

[0130] First, after the process board carrying the motor bracket 5 to be assembled arrives at the target workstation, the system will detect whether the motor bracket 5 is mounted on the process board. The system can obtain the model and information of the current motor bracket 5 through the RFID (Radio Frequency Identification) chip of the process board, and obtain the corresponding position parameters based on the model and information of the current motor bracket 5, wherein the position parameters include the target positions of the first transverse module 1051, the second transverse module 1052 and the third transverse module of the driving mechanism 105 of the position correction device 1.

[0131] Next, the first transverse module 1051 and the second transverse module 1052 first move to the target position, so that the position correction device 1 moves to the position directly above the motor bracket 5 .

[0132] Then the lifting cylinder 301 drives the lifting pin 303 to be inserted into the limiting hole 401 of the process plate. After the process plate is lifted, the vertical module 1053 descends to the target position in the z direction, and then the pressing mechanism 102 is controlled to descend and press the top of the motor bracket 5 to ensure that the top of the motor bracket 5 does not warp, so as to ensure the consistency of the position of the motor bracket 5 after position correction.

[0133] Then the first clamping mechanism 103 clamps the motor bracket 5 from both sides of the motor bracket 5 in the x direction, thereby correcting the position of the motor bracket 5 in the x direction, and the second clamping mechanism 104 clamps the motor bracket 5 from both sides of the motor bracket 5 in the y direction, thereby ensuring the position consistency of the motor bracket 5 in the y direction.

[0134] After the above actions are completed, the axial flow fan blade assembly line performs the assembly operation of the axial flow fan blade. After the assembly is completed, the whole machine flows out of the target workstation and the next whole machine flows in.

[0135] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope of protection claimed by the present invention.
