Description

Technical Field

[0001] This application relates to the field of automated assembly, and more particularly to an assembly apparatus. Background Technology

[0002] Cooling fans are important components to ensure the normal operation of equipment. For example, cooling fans installed on motors can accelerate the dissipation of heat generated during motor operation, so as to avoid the motor from failing to operate normally due to overheating.

[0003] Currently, when assembling a cooling fan onto equipment for installing cooling fans, the operator typically holds the cooling fan in their hand and places it onto one end of a shaft included in the equipment, so that in subsequent processes the cooling fan can be slid relative to the shaft to the target position on the shaft.

[0004] However, when assembling the cooling fan onto the aforementioned equipment, the operator must first align the slot on the cooling fan for inserting the shaft with the end of the shaft, and then fit the cooling fan onto the end of the shaft. Furthermore, since the cooling fan and shaft fit tightly, the operator usually has to use a hammer to tap it during installation, making the operation quite troublesome and resulting in low assembly efficiency for the cooling fan. Utility Model Content

[0005] In view of this, the assembly device provided in this application can improve the assembly efficiency of the cooling fan when assembling the cooling fan on the mounting end of the rotating shaft that drives the cooling fan to rotate.

[0006] This application provides an assembly device for assembling a cooling fan onto a mounting end of a rotating shaft that drives the cooling fan to rotate. The assembly device includes: a pick-and-place tool, a drive mechanism, and a frame. The pick-and-place tool is used to pick up and place the cooling fan. The drive mechanism is connected between the pick-and-place tool and the frame, driving the pick-and-place tool to rotate around its rotation axis and also driving the pick-and-place tool to move along the direction of the rotation axis. The rotation axis passes through the pick-and-place tool, and when the pick-and-place tool has picked up the cooling fan, the rotation axis coincides with the rotation axis of the cooling fan. When the cooling fan is assembled onto the mounting end, the rotation axis coincides with the axis of the rotating shaft. The frame moves the assembly device under the action of an external force.

[0007] In one possible implementation, the assembly device further includes a camera; the camera is connected to the frame, and when the pick-and-place tool has taken the cooling fan, and the frame moves the assembly device until the pick-and-place tool is close to the mounting end, both the cooling fan and the mounting end are within the camera's field of view, so that the frame continues to move the assembly device based on the image captured by the camera, until the target port of the cooling fan for inserting into the slot of the rotating shaft is opposite to the end face of the mounting end, and the distance between the target port and the mounting end is equal to the target distance, the drive mechanism Based on the image captured by the camera, the pick-and-place tool is rotated until the protrusion connected to the inner wall of the slot aligns with the keyway on the side wall of the rotating shaft. The drive mechanism then moves the pick-and-place tool along the rotation axis toward the mounting end until the mounting end is inserted into the slot from the target port, and at least part of the protrusion is inserted into the keyway. The length direction of the protrusion is parallel to the length direction of the slot, the length direction of the keyway is parallel to the length direction of the rotating shaft, and the end of the keyway near the mounting end passes through the rotating shaft.

[0008] In one possible implementation, the frame, the drive mechanism, and the pick-and-place tool are distributed along the direction of the rotation axis; the lens optical axis of the camera is parallel to the rotation axis and does not coincide with the rotation axis.

[0009] In one possible implementation, the assembly device further includes a clamping mechanism; the clamping mechanism is connected to the frame and is used to clamp a retaining ring, wherein the retaining ring is a component that relatively fixes the cooling fan and the rotating shaft.

[0010] In one possible implementation, the clamping mechanism includes a clamping seat and two jaws; the clamping seat is connected to the frame; the two jaws are arranged opposite to each other, and the first ends of the two jaws are slidably connected to the clamping seat along the direction in which the two jaws approach or move away from each other; the clamping seat is provided with a first driving member for driving the first ends of the two jaws to slide relative to the clamping seat; and the retaining spring is used to clamp between the second ends of the two jaws.

[0011] In one possible implementation, the drive mechanism includes a pusher and a rotating member; the pusher is connected between the pick-and-place tool and the rotating member, driving the pick-and-place tool to move along the direction of the rotation axis; the rotating member is connected between the pusher and the frame, driving the pusher and the pick-and-place tool to rotate around the rotation axis.

[0012] In one possible implementation, the rotating component is a rotary motor; the base of the rotary motor is connected to the frame, the rotor shaft of the rotary motor is connected to the pusher, and the axis of the rotor shaft of the rotary motor coincides with the rotation axis.

[0013] In one possible implementation, the pushing element is a cylinder; the cylinder barrel is connected to the rotor shaft of the rotary motor, the piston rod of the cylinder is connected to the picking and placing tool, and the length direction of the piston rod is parallel to the rotation axis.

[0014] In one possible implementation, the pick-and-place tool includes a tool base and multiple jaws; the tool base is connected to the drive mechanism; the multiple jaws are circumferentially distributed around the rotation axis, and the first end of each jaw is slidably connected to the tool base in a direction close to or away from the rotation axis. The tool base is provided with a second drive member for driving the first ends of the multiple jaws to slide relative to the tool base. When the pick-and-place tool has picked up the cooling fan, the second ends of the multiple jaws all abut against the inner wall of the slot in which the cooling fan is inserted into the rotating shaft.

[0015] In one possible implementation, the pick-and-place tool includes a total of three grippers.

[0016] As can be seen from the above technical solution, the assembly device includes a frame, a drive mechanism, and a pick-and-place tool. The drive mechanism is located between the frame and the pick-and-place tool. The frame can drive the assembly device to move, and the drive mechanism can drive the pick-and-place tool to rotate and move. The pick-and-place tool can pick up and place the cooling fan. When using the assembly device to assemble the cooling fan onto the mounting end, the cooling fan can first be picked up using the pick-and-place tool. Then, the frame drives the assembly device to move until the target port of the cooling fan slot is aligned with the end face of the mounting end, and the distance between the target port and the mounting end is equal to the target distance. The drive mechanism then drives the pick-and-place tool to rotate around the rotation axis until the protrusion connected to the inner wall of the slot is aligned with the keyway on the rotating shaft. Then, the drive mechanism drives the pick-and-place tool to move along the rotation axis towards the mounting end until the mounting end is inserted into the slot from the target port, and at least part of the protrusion is inserted into the keyway. At this time, the cooling fan is assembled onto the mounting end. Therefore, the assembly device can automatically assemble the cooling fan onto the mounting end of the shaft. Compared with manually assembling the cooling fan onto the mounting end, the assembly device can complete the assembly of the cooling fan more conveniently and quickly, and there is no need to use other tools to knock it, thus improving the assembly efficiency of the cooling fan.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] As mentioned earlier, cooling fans are crucial components for ensuring the normal operation of equipment. For example, cooling fans installed on motors can accelerate the dissipation of heat generated during motor operation, minimizing the risk of the motor malfunctioning due to overheating. Currently, when assembling cooling fans onto equipment, operators typically hold the fan and slip it onto one end of a shaft within the equipment, allowing for subsequent sliding of the fan relative to the shaft to its target position. However, this process requires operators to first align the slot on the fan with the end of the shaft before fitting the fan onto the shaft. Furthermore, due to the tight fit between the fan and the shaft, operators often need to use a hammer to tap the fan into place, making the process cumbersome and resulting in low assembly efficiency.

[0033] In this embodiment, the assembly device includes a frame, a drive mechanism, and a pick-and-place tool. The drive mechanism is disposed between the frame and the pick-and-place tool. The frame can drive the assembly device to move, and the drive mechanism can drive the pick-and-place tool to rotate and move. The pick-and-place tool can pick up and place the cooling fan. When using the assembly device to assemble the cooling fan onto the mounting end, the cooling fan can first be picked up using the pick-and-place tool. Then, the frame drives the assembly device to move until the target port of the cooling fan slot is opposite to the end face of the mounting end, and the distance between the target port and the mounting end is equal to the target distance. The drive mechanism then drives the pick-and-place tool to rotate around the rotation axis until the protrusion connected to the inner wall of the slot is opposite to the keyway on the rotating shaft. Then, the drive mechanism drives the pick-and-place tool to move along the rotation axis toward the mounting end until the mounting end is inserted into the slot from the target port, and at least part of the protrusion is inserted into the keyway. At this time, the cooling fan is assembled onto the mounting end. Therefore, the assembly device can automatically assemble the cooling fan onto the mounting end of the shaft. Compared with manually assembling the cooling fan onto the mounting end, the assembly device can complete the assembly of the cooling fan more conveniently and quickly, and there is no need to use other tools to knock it, thus improving the assembly efficiency of the cooling fan.

[0034] The assembly apparatus provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0035] The assembly device provided in this application embodiment is used to assemble a cooling fan onto the mounting end of a rotating shaft that drives the cooling fan to rotate. This application embodiment does not limit the specific application scenarios of the cooling fan and the rotating shaft. For example, the cooling fan can be a motor cooling fan, and the rotating shaft can be a rotating shaft at the tail of the motor used to mount the motor cooling fan.

[0036] Figure 1 This is a schematic diagram of a cooling fan provided in an embodiment of this application. (Refer to...) Figure 1The cooling fan 1 includes an inner column 11, a ring plate 12, multiple fan blades 13, and a protruding strip 14. The inner column 11 is a cylinder, and a slot 111 for inserting a rotating shaft 2 is opened through the inner column 11 along its length. The ring plate 12 is fixedly sleeved on one end of the inner column 11. The port of the slot 111 away from the ring plate 12 is the target port 1111. Multiple fan blades 13 are distributed in a circle around the axis of the inner column 11 on the outside of the inner column 11. The fan blades 13 are fixedly connected to the ring plate 12. The protruding strip 14 is long and parallel to the length of the inner column 11, that is, the length of the protruding strip 14 is parallel to the length of the slot 111. The protruding strip 14 is located in the slot 111 of the inner column 11 and is fixedly connected to the inner wall of the inner column 11.

[0037] Figure 2 This is a side view of a rotating shaft provided in an embodiment of this application. (Refer to...) Figure 2 One end of the rotating shaft 2 is the mounting end 21. A keyway 22 for accommodating the protruding strip is provided on the side wall of the rotating shaft 2. The length direction of the keyway 22 is parallel to the length direction of the rotating shaft 2. The end of the keyway 22 near the mounting end 21 passes through the rotating shaft 2.

[0038] Based on the aforementioned cooling fan 1 and hinge 2, when assembling the cooling fan 1 onto the mounting end 21, the target port 1111 of the slot 111 of the cooling fan 1 is brought close to the mounting end 21 of the hinge 2, and then the cooling fan 1 is fitted onto the mounting end 21 so that the mounting end 21 is inserted into the slot 111 from the target port 1111, and at least part of the protrusion 14 is inserted into the keyway 22.

[0039] Figure 3 This is a schematic diagram of an assembly device provided in an embodiment of this application. (Refer to...) Figure 1 , Figure 2 and Figure 3 The assembly device includes: a pick-and-place tool 3, a drive mechanism 4, and a frame 5; the pick-and-place tool 3 is used to pick up and place the cooling fan 1, that is, to pick up and release the cooling fan 1; the drive mechanism 4 is connected between the pick-and-place tool 3 and the frame 5, and is used to drive the pick-and-place tool 3 around its rotation axis (see...). Figure 3 The dotted line a) rotates and is also used to drive the pick-and-place tool 3 to move along the direction of the rotation axis. The rotation axis passes through the pick-and-place tool 3, and the rotation axis coincides with the rotation axis of the cooling fan 1 when the pick-and-place tool 3 has picked up the cooling fan 1. The rotation axis coincides with the axis of the rotating shaft 2 when the cooling fan 1 is assembled on the mounting end 21. The frame 5 drives the assembly device to move under the action of external force. The frame 5 can be used to connect external devices such as robotic arms that work with the assembly device, so that the external devices provide the frame 5 with the external force that drives the assembly device to move as a whole.

[0040] In this embodiment, the assembly device includes a frame 5, a drive mechanism 4, and a pick-and-place tool 3. The drive mechanism 4 is disposed between the frame 5 and the pick-and-place tool 3. The frame 5 can drive the assembly device to move, and the drive mechanism 4 can drive the pick-and-place device to rotate and move. The pick-and-place device can pick up and place the cooling fan 1. When using the assembly device to assemble the cooling fan 1 onto the mounting end 21, the cooling fan 1 can first be picked up using the pick-and-place tool 3, and then the frame 5 drives the assembly device to move until the target port 1111 of the slot 111 of the cooling fan 1 is aligned with the mounting end 21. With the end faces facing each other and the distance between the target port 1111 and the mounting end 21 equal to the target distance, the drive mechanism 4 then drives the pick-and-place tool 3 to rotate around the rotation axis until the protrusion 14 connected to the inner wall of the slot 111 aligns with the keyway 22 on the rotating shaft 2. Next, the drive mechanism 4 drives the pick-and-place tool 3 to move along the rotation axis towards the mounting end 21 until the mounting end 21 is inserted into the slot 111 from the target port 1111, and at least part of the protrusion 14 is inserted into the keyway 22. At this point, the cooling fan 1 is assembled onto the mounting end 21. Thus, the assembly device can automatically assemble the cooling fan 1 onto the mounting end 21 of the rotating shaft 2. Compared to manually assembling the cooling fan 1 onto the mounting end 21, the assembly device can complete the assembly of the cooling fan 1 more conveniently and quickly, without the need for hammering with other tools, thus improving the assembly efficiency of the cooling fan 1.

[0041] It should be noted that the specific value of the target spacing can be set according to actual needs, and this application embodiment does not limit it.

[0042] In one possible implementation, refer to Figure 3 The drive mechanism 4 includes a pusher 41 and a rotating member 42; the pusher 41 is connected between the pick-and-place tool 3 and the rotating member 42, and drives the pick-and-place tool 3 to move along the direction of the rotation axis; the rotating member 42 is connected between the pusher 41 and the frame 5, and drives the pusher 41 and the pick-and-place tool 3 to rotate around the rotation axis.

[0043] Therefore, the drive mechanism 4 can be realized by the pusher 41 and the rotating part 42, which has a simple structure and low cost.

[0044] In one possible implementation, refer to Figure 3 The rotating component 42 is a rotary motor, specifically a servo rotary motor; the base of the rotary motor is connected to the frame 5, the rotor shaft of the rotary motor is connected to the pusher 41, and the axis of the rotor shaft of the rotary motor coincides with the rotation axis. Thus, the rotating component 42 is easy to implement and has a small size.

[0045] In one possible implementation, refer to Figure 3The pushing component 41 is a cylinder, specifically a high-pressure pushing cylinder; the cylinder barrel is connected to the rotor shaft of the rotary motor, and the piston rod of the cylinder is connected to the picking and placing tool 3. The length direction of the piston rod of the cylinder is parallel to the rotation axis. Therefore, the rotating component 42 is easy to implement and has a small size.

[0046] Figure 4 This is an exploded view of an assembly apparatus provided in an embodiment of this application. (Refer to...) Figure 1 , Figure 2 and Figure 4 The pick-and-place tool 3 includes a tool base 31 and multiple claws 32. The tool base 31 is connected to the drive mechanism 4, specifically to the piston rod of a cylinder. The multiple claws 32 are circumferentially distributed around the axis of rotation. The first end of each claw 32 is slidably connected to the tool base 31 in a direction close to or away from the axis of rotation. The tool base 31 is provided with a second drive member for driving the first ends of the multiple claws 32 to slide relative to the tool base 31. The second drive member can drive the first ends of all the claws 32 to slide synchronously relative to the tool base 31 in a direction close to or away from the axis of rotation. When the pick-and-place tool 3 has picked up the cooling fan 1, the second ends of the multiple claws 32 abut against the inner wall of the slot 111 of the cooling fan 1 for inserting the shaft 2.

[0047] During the process of the pick-and-place tool 3 picking up the cooling fan 1, the second drive component can first control all the claws 32 to move closer to the rotation axis, so that the distance between the claws 32 and the rotation axis is smaller. Then, the frame 5 drives the assembly device to move until the second end of all the claws 32 is opposite to the target port 1111 of the slot 111 of the cooling fan 1. Then, the second end of all the claws 32 is inserted from the target port 1111 of the slot 111 of the cooling fan 1 into the slot 111. Then, the second drive component controls all the claws 32 to move away from the rotation axis, so that the second end of all the claws 32 is tightly abutting against the inner wall of the slot 111. At this time, the pick-and-place tool 3 and the cooling fan 1 are relatively fixed. The subsequent movement of the pick-and-place tool 3 will also drive the cooling fan 1 to move, that is, the pick-and-place tool 3 has picked up the cooling fan 1.

[0048] After the cooling fan 1 is assembled on the mounting end 21, the second drive unit controls all the claws 32 to move towards the direction of rotation axis. Then the pusher 41 can drive the pick-and-place tool 3 to move away from the mounting end 21 along the rotation axis, so that all the claws 32 are dislodged from the slot 111 of the cooling fan 1, thus realizing that the pick-and-place tool 3 releases the cooling fan 1.

[0049] Therefore, by setting multiple claws 32, the pick-and-place tool 3 can pick up the cooling fan 1 from the slot 111 of the cooling fan 1 when it picks up the cooling fan 1, and can also avoid the protruding strip 14 in the slot 111, thereby improving the positional stability of the cooling fan 1 relative to the pick-and-place tool 3 when it picks up the cooling fan 1.

[0050] In one possible implementation, refer to Figure 4 The pick-and-place tool 3 includes a total of three claws 32. Compared with two claws 32, three claws 32 can reduce the possibility of the cooling fan 1 tilting relative to the claws 32 when it is picked up, and improve the positional stability of the cooling fan 1 relative to the pick-and-place tool 3 when it is picked up.

[0051] In one possible implementation, refer to Figure 1 , Figure 2 and Figure 3 The assembly device also includes a camera 6. The camera 6 is connected to the frame 5. When the pick-and-place tool 3 has picked up the cooling fan 1 and the frame 5 moves the assembly device to the point where the pick-and-place tool 3 is close to the mounting end 21, both the cooling fan 1 and the mounting end 21 are within the shooting range of the camera 6. This allows the frame 5 to move the assembly device based on the image captured by the camera 6 until the target port 1111 of the slot 111 for inserting the cooling fan 1 into the rotating shaft 2 is opposite to the end face of the mounting end 21, and the distance between the target port 1111 and the mounting end 21 is equal to the target distance. The rotating component 42 then drives the pick-and-place tool 3 to rotate based on the image captured by the camera 6 until the protrusion 14 connected to the inner wall of the slot 111 is opposite to the keyway 22 opened on the side wall of the rotating shaft 2. The pushing component 41 then drives the pick-and-place tool 3 to move along the rotation axis toward the mounting end 21 until the mounting end 21 is inserted into the slot 111 from the target port 1111, and at least part of the protrusion 14 is inserted into the keyway 22.

[0052] Camera 6 can periodically capture images and transmit them to the control system. When the pick-and-place tool 3 has picked up the cooling fan 1, and the frame 5 moves the assembly device until the pick-and-place tool 3 is close to the mounting end 21, the control system determines the positional offset between the cooling fan 1 and the mounting end 21 based on the received image. Based on this positional offset, the control system controls the frame 5 to continue moving the assembly device until the target port 1111 of the slot 111 for inserting the rotating shaft 2 of the cooling fan 1 is opposite to the end face of the mounting end 21, and the distance between the target port 1111 and the mounting end 21 is equal to the target distance. The control system then determines the rotation angle offset of the cooling fan 1 and the mounting end 21 based on the received image, and controls the rotating component 42 to drive the pick-and-place tool 3 to rotate according to the rotation angle offset, so that the protrusion 14 connected to the inner wall of the slot 111 is opposite to the keyway 22 opened on the side wall of the rotating shaft 2. Finally, the control system can control the pushing component 41 to drive the pick-and-place tool 3 to move along the rotation axis towards the mounting end 21 until the mounting end 21 is inserted into the slot 111 from the target port 1111, and at least part of the protrusion 14 is inserted into the keyway 22.

[0053] Therefore, the camera 6 enables the pusher 41 and the rotating member 42 to move more precisely. Compared with pre-setting the motion data of the pusher 41 and the rotating member 42, the camera 6 in this application can make the assembly device more adaptable to changes in the application environment and improve the applicability of the assembly device.

[0054] In one possible implementation, refer to Figure 3 The frame 5, drive mechanism 4, and pick-and-place tool 3 are distributed along the direction of the rotation axis; the lens optical axis of the camera 6 is parallel to the rotation axis and does not coincide with the rotation axis.

[0055] Therefore, the optical axis of the camera 6 lens is parallel to the rotation axis of the pick-up and place tool 3, which makes the algorithm for determining the amount of movement of the pick-up and place tool 3 relative to the mounting end 21 simpler and saves computing resources.

[0056] In one possible implementation, refer to Figure 2 and Figure 3 The assembly device also includes a clamping mechanism 7; the clamping mechanism 7 is connected to the frame 5 and is used to clamp the retaining ring 8. The retaining ring 8 is a component that relatively fixes the cooling fan 1 and the rotating shaft 2 in subsequent processes. The clamping mechanism 7 and the camera 6 are located on both sides of the frame 5 to avoid mutual interference.

[0057] Therefore, the assembly device can not only assemble the cooling fan 1, but also carry the retaining ring 8 to the vicinity of the rotating shaft 2 to prepare for subsequent processes, so as to facilitate the subsequent processes.

[0058] In one possible implementation, refer to Figure 3 The clamping mechanism 7 includes a clamping seat 71 and two grippers 72; the clamping seat 71 is connected to the frame 5; the two grippers 72 are arranged opposite to each other, and the first ends of the two grippers 72 are slidably connected to the clamping seat 71 along the direction in which the two grippers 72 approach or move away from each other. The clamping seat 71 is provided with a first driving member for driving the first ends of the two grippers 72 to slide relative to the clamping seat 71, and a snap ring 8 is used to clamp between the second ends of the two grippers 72.

[0059] When clamping the snap ring 8 through the clamping mechanism 7, the snap ring 8 can be placed between the second ends of the two jaws 72. Then, the first driving member drives the two jaws 72 to move closer to each other so that the snap ring 8 is clamped between the second ends of the two jaws 72, thus realizing the clamping mechanism 7 clamping the snap ring 8. After that, the movement of the frame 5 will also drive the snap ring 8 to move. The clamping mechanism 7 has a simple structure, is easy to implement, and has a low cost.
