Description

Technical Field

[0001] This invention relates to an electric motor PCB board assembly equipment, belonging to the field of electric motor PCB board assembly technology. Background Technology

[0002] The motor requires a PCB board to be installed during assembly, such as Figure 2 and 3 As shown, during assembly, the PCB board needs to be pressed into the motor housing and secured with screws. However, current motor PCB board assembly methods rely on manual assembly, resulting in low automation, low efficiency, and low precision, failing to meet the demands of rapid motor production and high-quality motor products. Furthermore, manual screw tightening is not only inefficient but also easily generates dust, static electricity, and waste residue in the motor, severely impacting product quality.

[0043] like Figure 1-8 As shown, the present invention provides a motor PCB board assembly device, including a frame 601. A worktable 602 and a rotatable turntable 603 connected to the worktable 602 are disposed within the frame 601. A plurality of turntable clamps 605 are mounted on the turntable 603 for fixing a motor housing 606. A pressing mechanism 2 and a turning mechanism 4 are mounted on the worktable 602. A fixed platform 604 is disposed above the turntable 603. A first detection mechanism 1, a cleaning mechanism 3, and a second detection mechanism 5 are mounted on the fixed platform 604. The rotation of the turntable 603 causes the motor housing 606 on the turntable clamps 605 to pass through the first detection mechanism 1, the pressing mechanism 2, and the cleaning mechanism 3. The assembly includes a screwing mechanism 4 and a second inspection mechanism 5; the first inspection mechanism 1 and the second inspection mechanism 5 are used to inspect the assembly quality of the PCB board 607; the pressing mechanism 2 is used to press the PCB board 607 into the motor housing 606; the cleaning mechanism 3 includes a movable cover 305, which is connected to a plasma airflow; the cover 305 is moved to cover the motor housing 606; the cleaning mechanism 3 is used to clean the motor housing 606 and eliminate static electricity; the screwing mechanism 4 includes a movable screwdriver 407, which can extend into the cover 305 and screw screws 609 onto the PCB board 607 and the motor housing 606 to fasten the PCB board 607 into the motor housing 606.

[0044] Optionally, in some embodiments, a turntable drive motor (not shown in the figure) is connected below the turntable 603, and the turntable drive motor is used to drive the turntable 603 to rotate.

[0045] Optionally, in some embodiments, the first detection mechanism 1 includes a first lifting module 101 connected to the fixed platform 604. A camera 102 and a camera light source 103 are connected above the first lifting module 101. The camera 102 is located above the camera light source 103 and faces the turntable clamp 605 on the turntable 603. At least one first laser sensor 104 is connected below the first lifting module 101. The first laser sensor 104 faces the turntable clamp 605 on the turntable 603. In this embodiment, a robot grips the motor housing 606 and delivers it to the turntable fixture 605 on the turntable 603. Upon startup, the first laser sensor 104 detects whether the motor housing 606 is level. If it is level, the next step is executed; otherwise, the turntable fixture 605 does not process the product and issues an alarm, requiring manual adjustment of the motor housing 606. Next, the robot grips the PCB board 607 and places it inside the motor housing 606. The camera 102 takes a picture of the motor product below to detect whether the IDC socket on the PCB board 607 is properly positioned. If it is, the next step is executed; otherwise, the turntable fixture 605 does not process the product at that location and issues an alarm.

[0046] Optionally, such as Figure 9-11As shown, in some embodiments, the pressing mechanism 2 includes a mounting plate 201 fixedly connected to the worktable 602. A first cylinder 202 is mounted above the mounting plate 201, and a third cylinder 209 is mounted below the mounting plate 201. The output end of the first cylinder 202 is connected to a pressing head 203, and the output end of the third cylinder 209 is connected to a turntable clamp 605. A motor housing 606 is fixed on the turntable clamp 605, and the motor housing 606 is located below the pressing head 203. The output end of the third cylinder 209 is connected to the turntable clamp 605 via a connecting block 204. The turntable clamp 605 is located between the connecting block 204 and the pressure head 203; the mounting plate 201 is fixedly connected to the limiting base 207; a movable limiting block 206 is provided on one side of the connecting block 614; the limiting base 207 is fixedly connected to the second cylinder 205 and the slide rail 208; the slide rail 208 is slidably connected to the limiting block 206; the output end of the second cylinder 205 is connected to the limiting block 206; the second cylinder 205 is used to drive the limiting block 206 to move within the slide rail 208; the output end of the third cylinder 209 passes through the limiting base 207 and abuts against the connecting block 204. After the third cylinder 209 lifts the turntable clamp 605 upward through the connecting block 204, the second cylinder 205 pushes the limiting block 206 to move towards the connecting block 204, so that the connecting block 204 abuts against the limiting block 206. Then, the connecting block 204, the turntable clamp 605 and the motor housing 606 are all mounted on the limiting block 206. The third cylinder 209 returns to its original position, so that the third cylinder 209 is not subjected to pressure during the subsequent pressing process and is thus protected from damage. The first cylinder 202 pushes the pressure head 203 to press down the PCB board 607 inside the motor housing 606, and presses the PCB board 607 tightly into the motor housing 606.

[0047] Optionally, the mounting plate 201 is arranged vertically, and the limiting base 207 is arranged horizontally.

[0048] Optionally, such as Figure 12 and 13As shown, in some embodiments, the cleaning mechanism 3 includes a first fixed base 301 fixedly connected to the fixed platform 604. A second lifting module 302 is fixedly connected to the first fixed base 301. A fourth cylinder 303 is connected to the second lifting module 302. The output end of the fourth cylinder 303 is connected to a first connecting plate 304. A cover 305 is connected below the first connecting plate 304. The cover 305 connects to a plasma suction head 307 and at least one plasma blower head 306. The plasma blower head 306 is externally connected to a plasma air inlet pipe, and the plasma suction head 307 is externally connected to a plasma air outlet pipe. A connection hole 308 is provided at the connection between the first connecting plate 304 and the cover 305. The fourth cylinder 303 is used to drive the first connecting plate 304 and the cover 305 to move, so that the cover 305 covers the motor housing 606 on the turntable clamp 605. Plasma air enters the housing 305 from the plasma air blower 306, while the plasma air suction head 307 sucks away the plasma air from the housing 305. This process allows the plasma air to enter the housing 305 from the plasma air blower 306 and exit from the plasma air suction head 307, thereby achieving the functions of removing static electricity, dust, and cleaning the motor housing 606, as well as removing waste generated during screwing, ensuring the quality of the motor product.

[0049] Optionally, such as Figure 14-17As shown, in some embodiments, the screwing mechanism 4 includes a third lifting module 401 fixedly connected to the worktable 602. A horizontal plate 402 is connected to the upper end of the third lifting module 401. A horizontal cylinder 403 is fixedly connected to the horizontal plate 402. A vertical plate 404 is connected to the output end of the horizontal cylinder 403. A horizontal guide rail is provided on the horizontal plate 402, and the vertical plate 404 is slidably connected to the horizontal guide rail. A vertical cylinder 405 is fixedly connected to the vertical plate 404, and a screw-operated connecting plate 406 is connected to the output end of the vertical cylinder 405. The screw machine 407 is fixedly connected to the screw machine connecting plate 406. A vertical guide rail is provided on the vertical plate 404, and the screw machine connecting plate 406 is slidably connected to the vertical guide rail. The horizontal cylinder 403 drives the vertical plate 404, the vertical cylinder 405, the screw machine connecting plate 406, and the screw machine 407 to move laterally along the horizontal guide rail on the horizontal plate 402. The vertical cylinder 405 drives the screw machine connecting plate 406 and the screw machine 407 to move vertically along the vertical guide rail on the vertical plate 404, thereby realizing the lateral and vertical movement of the screw machine 407. The screw head of the screw machine 407 can pass through the connecting hole 308 of the cleaning mechanism 3 and extend into the cover 305. The screw machine 407 screws into the PCB board 607 after it has been pressed by the pressing mechanism 2, causing the screws 609 to pass through the PCB board 607 and tightly lock it inside the motor housing 606. While screwing screws, the cleaning mechanism 3 of the screw-driving machine 407 cleans up the waste generated during screw-driving to prevent dust, static electricity, waste and other impurities generated during screw-driving from affecting the quality of the motor products.

[0050] Optionally, the screw-driving machine 407 also has a waste screw channel 408 connected to its head. The other end of the waste screw channel 408 is connected to a waste screw box 409, which contains a sensor for detecting whether a screw 609 has passed through. Since the screw-driving machine 407 itself does not have the function of detecting the presence of screws 609, and to ensure that screws 609 are present in the screw-driving machine 407 during subsequent screw-driving operations, preventing the screw-driving machine 407 from emptying the PCB board 607, a waste screw box 409 is provided to detect the presence of screws 609. Before screw-driving, the screw-driving machine 407 performs a screw-dispensing action, allowing the screw to slide into the waste screw box 409 through the waste screw channel 408. If the waste nail box 409 detects a screw 609 passing through, it means that the screw machine 407 has a screw, allowing it to screw onto the PCB board 607 normally. If the waste nail box 409 detects no screw 609 passing through, it means that the screw machine 407 is empty, and the equipment issues an alarm, stopping the screw machine 407 from screwing onto the PCB board 607 to prevent empty screws. After manually replenishing the screw machine 407 with screws 609, it can resume screwing onto the PCB board 607 normally. This ensures that the screw machine 407 can drive the screw 609 onto the PCB board 607 every time, avoiding empty screws due to a lack of screws, ensuring the fastening quality of the PCB board 607, and thus guaranteeing the quality of the motor products.

[0051] It should be noted that the screw machine 407 is an existing automatic screw driving machine, and its structure will not be described in detail.

[0052] Optionally, such as Figure 18-20As shown, in some embodiments, the second detection mechanism 5 includes a mounting base 501 connected to the fixed platform 604. A fifth cylinder 502 is mounted on the mounting base 501. The output end of the fifth cylinder 502 is connected to an L-shaped second connecting plate 503. A mounting bracket 507 is fixedly connected below the second connecting plate 503. A positioning post 514 is connected to the mounting bracket 507. A ring 510 is connected to the bottom end of the mounting bracket 507 via a pin 508. Arc-shaped connecting blocks 506 are fixedly connected to both ends of the inner side of the mounting bracket 507. Each arc-shaped connecting block 506 is fixedly connected to two springs. The buffer head 505 has a pressure plate 509 slidably connected to the inner side of the arc-shaped connecting block 506. A first fixing block 511 is fixedly connected to the lower inner side of several pressure plates 509, and a second fixing block 513 is fixedly connected to the upper inner side of several pressure plates 509. Several pressure pins 512 are fixedly connected below the first fixing block 511. Several second sensors 504 are provided on the second connecting plate 503. Several second sensors 504 pass through the second connecting plate 503, the mounting bracket 507, the second fixing block 513, the first fixing block 511, and are connected to several pressure pins 512 in a one-to-one correspondence.

[0053] The previous process of assembling the motor PCB board 607 involves pressing the copper wires inside the motor into the motor housing 606 using pins 608. During the assembly of the motor PCB board 607, insertion holes 610 are formed on the PCB board 607. After the PCB board 607 is assembled inside the motor, the pins 608 extend out of the PCB board 607 through the insertion holes 610. However, during the assembly of the motor PCB board 607, the pins 608 are easily bumped, causing them to become misaligned. This affects the securing effect of the pins 608 on the copper wires inside the motor, thus affecting the quality of the motor product. Therefore, this embodiment uses a second detection mechanism 5 to detect the height process parameter of the pins 608, thereby detecting the impact of the PCB board 607 assembly on the pins 608. Specifically, because the upper surface of the motor housing 606 is not perfectly horizontal, there is a height difference. The fifth cylinder 501 is activated, driving the second connecting plate 503, mounting bracket 507, arc-shaped connecting block 506, elastic buffer head 505, and positioning post 514 to move downwards. The positioning post 514 moves to a set position, transmitting its force to the pressure plate 509 below. The pressure plate 509 drives the second fixing block 513, the first fixing block 511, and several pressure pins 512 to move downwards, thereby abutting the several pressure pins 512 against the pins 608 on the PCB board 607. To eliminate the aforementioned height difference, the ring 510 can rotate around the pin shaft 508 at a certain angle. The elastic buffer heads 505 on both sides of the arc-shaped connecting block 506 can abut against the ring 510 and have an elastic buffering effect, which can play a floating role in two different directions and at different heights. This allows the ring 509 and the first fixing block 511 to adapt to the upper surface of the motor housing 606 at different heights, enabling the second detection mechanism 5 to completely fit against the motor housing 606. Several second sensors 504 contact the pins 608 one by one through several pressure pins 512, thereby detecting the height process parameters of each pin 608 and detecting those that do not meet the specified process parameter range, thus ensuring the quality of motor products.

[0054] Furthermore, the present invention also provides a method for assembling a motor PCB board, which utilizes the aforementioned motor PCB board assembly equipment, and includes the following steps:

[0055] Step 1: The robot picks up the motor housing 606 and delivers it to the turntable fixture 605 on the turntable 603. The equipment starts, and the first laser sensor 104 detects whether the motor housing 606 is level. If it is level, proceed to the next step; if it is not level, the turntable fixture 605 will not process the product and will issue an alarm, requiring manual adjustment of the motor housing 606. Next, the robot picks up the PCB board 607 and places it inside the motor housing 606. The camera 102 takes a picture of the motor product below to detect whether the IDC socket on the PCB board 607 is in place. If it is detected that it is in place, proceed to the next step; if it is not detected that it is in place, the turntable fixture 605 will not process the product at that location and will issue an alarm.

[0056] Step 2: Turntable 603 starts, rotating motor housing 606 to the station of pressing mechanism 2. Once the product is in place, the program receives the instruction. Third cylinder 209 lifts turntable clamp 605 upwards via connecting block 204. Second cylinder 205 pushes limit block 206 towards connecting block 204, causing connecting block 204 to abut against limit block 206. This allows connecting block 204, turntable clamp 605, and motor housing 606 to all be mounted on limit block 206. Third cylinder 209 returns to its original position, preventing pressure and damage during subsequent pressing. First cylinder 202 pushes press head 203 downwards to press PCB board 607 inside motor housing 606, tightly pressing PCB board 607 into motor housing 606. The pressing process for PCB board 607 is complete.

[0057] Step 3: Turntable 603 starts, rotating motor housing 606 to the workstation of screwing mechanism 4 and cleaning mechanism 3. Once the product is in position, the PLC receives program information and the screwing mechanism 4 performs a screw ejection action, sliding the screw into the waste screw box 409 through the waste screw channel 408. Sensors installed in the waste screw box 409 detect whether a screw 609 has passed through. If the waste screw box 409 detects a screw 609, it means there is a screw in the screw machine 407, allowing the screw machine 407 to normally screw onto the PCB board 607. If the waste screw box 409 detects no screw 609, it means there is no screw in the screw machine 407, and the equipment issues an alarm, stopping the screw machine 407 from screwing onto the PCB board 607 to prevent empty screws. After manually replenishing the screw machine 407 with screws 609, the screw machine 407 can resume normal screwing onto the PCB board 607. The fourth cylinder 303 drives the first connecting plate 304 and the cover 305 to move, so that the cover 305 is placed on the motor housing 606 on the turntable fixture 605; the horizontal cylinder 403 and the vertical cylinder 405 drive the screw machine 407 to move, so that the head of the screw machine 407 passes through the connecting hole 308 of the cleaning mechanism 3 and extends into the cover 305. The screw machine 407 screws the PCB board 607 after it has been pressed by the pressing mechanism 2, so that the screw 609 passes through the PCB board 607 and tightly locks it in the motor housing 606. While the screw machine 407 is tightening screws, the cleaning mechanism 3 is activated. The cleaning mechanism 3 performs static electricity removal, dust removal, and cleaning of the waste generated by the screw machine 407 during screw tightening inside the motor housing 606. The horizontal cylinder 403 drives the screw machine 407 to move horizontally and tighten screws at two locations on the PCB board 607 that need to be fastened. After tightening the screws, the screw machine 407 detects the position and torque of the screws. If the screw position is abnormal or the torque exceeds the set detection range, the product is unqualified and the screw tightening is complete.

[0058] Step 4: Turntable 603 is started, rotating motor housing 606 to the station of the second detection mechanism 5. The fifth cylinder 501 is activated, driving the second connecting plate 503, mounting bracket 507, arc-shaped connecting block 506, elastic buffer head 505, and positioning post 514 downwards. The positioning post 514 moves to a set position, transferring its force to the pressure plate 509 below. The pressure plate 509 drives the second fixing block 513, the first fixing block 511, and several pressure pins 512 downwards, thus placing the pressure pins 512 one by one against the pins 608 on the PCB board 607. This is to eliminate... The aforementioned height difference allows the ring 510 to rotate around the pin 508 at a certain angle. The elastic buffer heads 505 on both sides of the arc-shaped connecting block 506 can abut against the ring 510 and provide elastic buffering, enabling floating in two different directions and at different heights. This allows the ring 509 and the first fixing block 511 to adapt to the upper surface of the motor housing 606 at different heights, ensuring that the second detection mechanism 5 is completely fitted onto the motor housing 606. Several second sensors 504 contact the pins 608 one by one through several pressure pins 512, thereby detecting the height process parameters of each pin 608. If the detected height is outside the specified process parameter range, a product defect information is sent.

[0059] In the above steps, if the equipment detects that a product is unqualified, the subsequent workstations will no longer process or test that product. After the process is completed, the robot will remove the unqualified product and put it into the unqualified product box. If the product is qualified throughout the process, after the process is completed, the robot will put the product to the next workstation to continue the assembly.

[0060] This invention features a precise structure, accurate operation, high precision, high automation, and high work efficiency. Through the coordinated layout of the first detection mechanism, pressing mechanism, cleaning mechanism, screwing mechanism, and second detection mechanism, it achieves automated assembly of the PCB board into the motor, ensuring a tight fit. The first detection mechanism detects whether the IDC connectors on the PCB board are properly positioned, guaranteeing product quality. The pressing mechanism firmly presses the PCB board into the motor housing, preventing damage to the third cylinder during the pressing process. The cleaning mechanism performs static electricity removal, dust removal, and cleaning of waste generated during screwing inside the motor housing. The screwing mechanism automates the screwing process, ensuring the screws pass through the PCB board and are securely locked inside the motor housing. A sensor within the waste screw box detects the presence of screws, guaranteeing that the screwing machine always drives screws onto the PCB board, preventing missed screws and ensuring the PCB board's fastening quality, motor product quality, and assembly efficiency. A second detection mechanism measures the height of each pin, identifying pins that do not meet specifications and ensuring effective fastening of the pins to the internal copper wires of the motor, thus guaranteeing motor product quality and PCB board assembly accuracy.
