Description

Technical Field

[0001] This invention relates to the field of intelligent manufacturing technology, specifically to a position correction device and an axial flow fan assembly line. Background Technology

[0002] In automated production lines, the positions of the devices to be processed must be corrected before processing can begin. Taking the assembly of axial flow fan blades as an example, axial flow fan blades are usually mounted on a motor bracket via a motor. Before assembling the axial flow fan blades, the position of the motor bracket needs to be corrected.

[0003] However, the motor bracket itself is attached to the condenser component, and due to the influence of the condenser component, the motor bracket tends to tilt forward, backward, and left or right, making it difficult to guarantee the positional consistency of the motor bracket after correction. Summary of the Invention

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

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

[0006] Base frame;

[0007] The pressing mechanism, connected to the base frame, can descend and press the workpiece;

[0008] The first clamping mechanism and the second clamping mechanism are capable of opening and closing in the horizontal direction and clamping the workpiece. 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 drive mechanism, connected to the base frame, is capable of driving the base frame to move.

[0010] Beneficial effects: During use, the position correction device of the present invention allows the drive mechanism to drive the base frame to the target workstation. Then, the pressing mechanism descends and presses down on the motor bracket, ensuring that the top of the motor bracket does not tilt, preventing forward or backward tilting, or left or right deviation. This avoids the motor bracket tilt affecting the consistency of the corrected motor bracket position. Next, the first and second clamping mechanisms limit the motor bracket from the x and y directions respectively, thereby completing the correction of the motor bracket, resulting in good consistency of the corrected motor bracket.

[0011] Furthermore, the position correction device of this application embodiment can correct the motor bracket from both sides and top, thereby avoiding the difficulty of the position correction device being inserted between the motor bracket and the condenser when the size of the housing is small. The position correction device of this application embodiment is applicable to the position correction of small-sized air conditioner outdoor units and has a wide range of applications.

[0012] In one alternative embodiment, the first clamping mechanism includes a pair of first clamping members disposed opposite each other, each first clamping member comprising:

[0013] The first paragraph extends downwards;

[0014] The second segment connects to the lower part of the first segment and extends toward the other first clamping member.

[0015] Beneficial effects: With this configuration, 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 the motor bracket on both sides along the x-direction without a large stroke, and can increase the interference after clamping.

[0016] In one alternative embodiment, the first clamping mechanism includes:

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

[0018] Beneficial effect: The opening and closing motion of the two first clamping parts driven by the first centering cylinder helps to improve the accuracy of the first clamping mechanism in positioning the motor bracket.

[0019] In one alternative embodiment, the second clamping mechanism includes a pair of second clamping members disposed opposite each other, each second clamping member comprising:

[0020] The third section extends downwards;

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

[0022] Beneficial effects: The third and fourth segments can together form a Z-shaped second clamping member, thereby increasing the distance between the fourth segments of the two second clamping members. This allows the distance between the two second clamping members to 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, thus effectively preventing the second clamping mechanism from interfering with the rear hook of the motor bracket during movement.

[0023] In one alternative implementation, a limiting insert is formed at the bottom of the fourth segment.

[0024] Beneficial effects: The limiting block can be inserted into the mating hole at the top of the hook, thereby clamping the top of the hook and limiting its position. It does not need to extend fully between the hook and the condenser, thus avoiding the difficulty of the second clamping member reaching deep into the motor bracket and condenser when the overall size of the unit is small, which would limit the applicability of the position correction device. The position correction device of this application embodiment is applicable to correcting the dimensions of the motor bracket of a 0.75p air conditioner outdoor unit, and has a wide range of applications.

[0025] In one alternative embodiment, the second clamping mechanism includes:

[0026] The second splitting cylinder is located at the bottom of the base frame. The second clamping member is connected to the second splitting cylinder. The two second clamping members can perform opening and closing movements under the action of the second splitting cylinder.

[0027] Beneficial effects: The opening and closing motion of the two second clamping parts driven by the second centering cylinder helps to improve the accuracy of the second clamping mechanism in positioning the motor bracket.

[0028] In one alternative implementation, the drive mechanism includes:

[0029] First horizontal module;

[0030] The second lateral module is connected to the power output end of the first lateral module, and the first lateral module can drive the second lateral module to move along the 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 effects: With this configuration, the first and second horizontal modules can cooperate with each other and drive the base to move in the horizontal plane. The vertical module can raise and lower the base, and the drive mechanism can drive the base to move within the space 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] Secondly, the present invention also 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 located below the position correction device.

[0036] Beneficial Effects: The axial flow fan assembly line of the second aspect of this invention includes or uses the axial flow fan of the first aspect of this invention, thus possessing beneficial effects. Specifically, it ensures that the top of the motor bracket does not tilt, preventing forward, backward, or left / right tilting of the motor bracket, and avoiding any impact on the consistency of the corrected motor bracket position due to bracket tilting. Furthermore, the first and second clamping mechanisms can respectively limit the motor bracket from the x and y directions, thereby completing the correction of the motor bracket, and resulting in good consistency of the corrected motor bracket.

[0037] In one optional embodiment, the conveying mechanism includes a base and a conveyor belt, the conveyor belt being disposed on the base and capable of moving along the length of the base. The axial flow fan assembly line further includes:

[0038] The lifting mechanism, located on the base and spaced apart from the conveyor belt, is used to lift the motor support.

[0039] Beneficial effects: With this configuration, when the motor bracket to be processed moves to the target station on the conveyor mechanism, the lifting mechanism can lift the motor bracket to be processed, thereby disengaging the motor bracket from the drive mechanism. This can limit the movement of the motor and prevent the vibration generated during the transmission of the conveyor mechanism from causing the motor bracket to vibrate, thus affecting the accuracy of the position correction.

[0040] In one optional embodiment, the conveying mechanism is further provided with a carrier component, which is disposed on the conveyor belt and is used to support the motor bracket to be processed. The lifting mechanism includes:

[0041] Lifting cylinder, connected to the base;

[0042] The lifting plate is connected to the power output end of the lifting cylinder and can be raised and lowered under the drive of the lifting cylinder.

[0043] A lifting pin is provided on the lifting plate, and the supporting component is provided with a limiting hole that can accommodate the lifting pin.

[0044] Beneficial effect: When the motor bracket to be processed reaches the target station, the lifting cylinder can extend and drive the lifting plate to move upward with the lifting pin. The lifting pin can be inserted into the limiting hole on the bearing, thereby limiting the motor bracket while lifting it. Attached Figure Description

[0079] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0080] The air conditioner outdoor unit and air cooler include a housing 7, a condenser 6, a motor bracket 5, a motor, and axial fan blades. The condenser 6 is located inside the housing 7. The motor bracket 5 is connected to the condenser 6 via a hook 501. The motor is mounted on the motor bracket 5, and the axial fan blades are mounted on the output shaft of the motor.

[0081] Taking the installation process of the axial flow fan blades of the outdoor unit of the air conditioner as an example, in order to achieve 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. Moreover, the whole unit has a variety of different models, such as 0.75P, 1P and 1.5P (where P represents "horsepower", which refers to the power consumption of the air conditioner). This requires the position correction device 1 to be compatible with different sizes of models.

[0082] In related technologies, the position correction device 1 typically needs to extend between the motor bracket 5 and the condenser 6 to clamp and correct the motor bracket 5. However, for smaller models, 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. For example, when the air conditioner is 1P or 1.5P, the distance between the condenser 6 and the motor bracket 5 is approximately 60mm.

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

[0084] Furthermore, since the rear side of the motor bracket 5 overlaps with the sponge of the condenser 6, the sponge may peel up, causing the hook 501 on the rear side of the motor bracket 5 to lift up, resulting in interference between the position correction device 1 and the hook 501 of the motor bracket 5.

[0085] The following is combined Figures 1 to 18 The following describes embodiments of the present invention.

[0086] According to an embodiment of the present invention, in one aspect, a position correction device 1 is provided, such as... 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 descend 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. The opening and closing direction of the first clamping mechanism 103 and the opening and closing direction of the second clamping mechanism 104 form an angle. The driving mechanism 105, connected to the base frame 101, can drive the base frame 101 to move.

[0088] For ease of description, 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 this application, the size of 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] In use, the position correction device 1 of the present invention drives the base frame 101 to the target workstation via the drive mechanism 105. Then, the pressing mechanism 102 descends and presses down on the motor bracket 5, ensuring that the top of the motor bracket 5 does not tilt, preventing forward or backward tilting, or left or right deviation. This avoids affecting the consistency of the corrected motor bracket 5 position due to tilting. Next, the first clamping mechanism 103 and the second clamping mechanism 104 limit the motor bracket 5 from the x and y directions respectively, thereby completing the correction of the motor bracket 5, resulting in good consistency of the corrected motor bracket 5.

[0091] Furthermore, the position correction device 1 of this application embodiment can correct the motor bracket 5 from both sides and the top, thereby avoiding the difficulty of the position correction device 1 extending between the motor bracket 5 and the condenser 6 when the size of the housing 7 is small. The position correction device 1 of this application embodiment can be applied to the position correction of small-sized air conditioner outdoor units and has a wide range of applications.

[0092] In one embodiment, the pressing mechanism 102 is located 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 pressing the motor bracket 5 off-center, and at the same time will not interfere with the first clamping mechanism 103 and the second clamping mechanism 104.

[0093] In one embodiment, such as 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 mounted on the base 201, and the telescopic rod passes through the linear bearing. The bottom end of the telescopic rod has a protruding pressing part, and the spring is sleeved on the telescopic rod and supported between the linear bearing and the pressing part.

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

[0095] The first segment 10321 extends downward. The second segment 10322 is connected to the lower part of the first segment 10321 and extends in a direction close to the other first clamping member 1032.

[0096] With this configuration, the second segment 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 in the x direction without a large stroke, and can increase the interference after clamping.

[0097] As a possible implementation, in one embodiment not shown in the accompanying drawings, the opposing surfaces of the two first clamping members 1032 both extend in a vertical direction.

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

[0099] The first centering cylinder 1031 drives the two first clamping parts 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 an alternative implementation, in an embodiment not shown in the accompanying drawings, the first clamping mechanism 103 may also be an electric gripper.

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

[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 at the middle position of the first clamping mechanism 103, the movement of the first clamping mechanism 103 and the second clamping mechanism 104 can be made simpler and more compact while the movement of the second clamping mechanism 104 does not interfere with each other.

[0104] In one embodiment, such as 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 segment 10421 and a fourth segment 10422.

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

[0106] The third segment 10421 and the fourth segment 10422 can together form a Z-shaped second clamping member 1042, thereby increasing the distance between the fourth segments 10422 of the two second clamping members 1042. This makes the distance between the two second clamping members 1042 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 tilt of the hook 501 of the motor bracket 5, thereby effectively preventing the second clamping mechanism 104 from interfering with the rear hook 501 of the motor bracket 5 during movement.

[0107] As a possible implementation, in an embodiment not shown in the accompanying drawings, the third segment 10421 and the fourth segment 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 located 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 splitting cylinder 1041 drives the two second clamping parts 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 an alternative implementation, in an embodiment not shown in the accompanying drawings, the second clamping mechanism 104 may also be an electric gripper.

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

[0112] In one embodiment, such as Figure 13 and Figure 14 As shown, a limiting plug is formed at the bottom of the fourth segment 10422.

[0113] The limiting block can be inserted into the mating hole 5011 at the top of the hook 501, thereby clamping the top of the hook 501 and limiting its position. It does not need to fully extend between the hook 501 and the condenser 6, thus avoiding the problem of the second clamping member 1042 being difficult to penetrate into the motor bracket 5 and the condenser 6 when the overall size of the unit is small, which would reduce the applicability of the position correction device 1. The position correction device 1 of this application embodiment is applicable to correcting the size of the motor bracket 5 of a 0.75p air conditioner outdoor unit, and has a wide range of applications.

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

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

[0116] With this configuration, 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 raise and lower the base 201, and the drive mechanism 105 can drive the base 201 to move within the space 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 an alternative implementation, the drive mechanism 105 may also be a robotic arm.

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

[0119] According to an embodiment of the present invention, another aspect provides an axial flow fan blade assembly line, including a position correction device 1 and a conveying mechanism 2 provided in the first aspect of the present invention. The conveying mechanism 2 is disposed below the position correction device 1.

[0120] The axial flow fan 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 therefore has the beneficial effect of ensuring that the top of the motor bracket 5 does not tilt, avoiding the phenomenon of forward tilting, backward tilting, or left and right deviation of the motor bracket 5, and avoiding the influence of the tilt of the motor bracket 5 on 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 y direction respectively, thereby completing the correction of the motor bracket 5, and the consistency of the corrected motor bracket 5 is good.

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

[0122] With this configuration, when the motor bracket 5 to be processed moves to the target station on the conveying mechanism 2, the lifting mechanism 3 can lift the motor bracket 5 to be processed, thereby disengaging the motor bracket 5 from the drive mechanism 105. This can limit the motor to be processed and prevent the vibration of the conveying mechanism 2 from causing the motor bracket 5 to vibrate, thus affecting the accuracy of the position correction.

[0123] As an alternative implementation, the conveying mechanism 2 can also be configured to stop moving when the motor support 5 to be processed moves to the target work position, so that the position correction device 1 can correct the position of the motor support 5 at the target work position.

[0124] In one embodiment, such as Figure 15 As shown, the conveying mechanism 2 is also equipped with a carrier 4, which is located on the conveyor belt 202 and is used to support 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 raised and lowered under the drive of the lifting cylinder 301. The lifting pin 303 is provided on the lifting plate 302, and the bearing member 4 is provided with a limiting hole 401 that can accommodate the lifting pin 303.

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

[0127] In one embodiment, the support member 4 is provided with a positioning pin 402, which can be inserted into the positioning hole 701 on the motor bracket 5, thereby fixing the motor bracket 5 on the support member 4 and effectively preventing the motor bracket 5 from moving back and forth or left and right.

[0128] Among them, the carrier 4 is preferably, but not limited to, a process plate.

[0129] The following describes the usage process of the axial flow fan blade assembly line according to an embodiment of the present invention:

[0130] First, after the process board carrying the motor bracket 5 to be assembled arrives at the target station, the system will detect whether the process board is equipped with the motor bracket 5. 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. The position parameters include the target positions of the first horizontal module 1051, the second horizontal module 1052 and the third horizontal module of the drive mechanism 105 of the position correction device 1.

[0131] Next, the first horizontal module 1051 and the second horizontal module 1052 move to the target position, thereby positioning the position correction device 1 directly above the motor bracket 5.

[0132] Then, the lifting cylinder 301 drives the lifting pin 303 to insert into the limiting hole 401 of the process plate, lifting the process plate. After that, the vertical module 1053 descends to the target position in the z direction. 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 tilt, so as to ensure the consistency of the position of the motor bracket 5 after the position is corrected.

[0133] Then, the first clamping mechanism 103 clamps the motor bracket 5 from both sides in the x direction to correct the position of the motor bracket 5 in the x direction. The second clamping mechanism 104 clamps the motor bracket 5 from both sides in the y direction to ensure the positional consistency of the motor bracket 5 in the y direction.

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

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