Description

Technical Field

[0001] This invention relates to the field of power adapter processing equipment technology, specifically to automatic assembly equipment for power adapter PCB boards. Background Technology

[0002] A laptop power adapter is an external switching power supply device designed specifically for laptops. Its main function is to convert high-voltage AC power from the mains into stable low-voltage DC power suitable for laptops, thereby ensuring that the laptop battery is charged safely and stably.

[0003] The automatic assembly equipment for power adapter PCB boards is mainly used for press-fitting PCB boards and power adapter housings. It can stably feed the PCB board into the housing and cooperate with the internal positioning posts, post sleeves, support ribs and other structures to ensure that the PCB board and housing are firmly assembled and improve the processing efficiency of laptop power adapters.

[0004] However, existing automatic power adapter PCB assembly equipment lacks precision and stability in the press-fitting and positioning of the PCB board and power adapter housing, thus reducing the stability of the assembly. Furthermore, the integrated processing efficiency of the existing automatic power adapter PCB assembly equipment in terms of loading, positioning, assembly, and unloading of the PCB board and power adapter housing is insufficient, further reducing the assembly speed per unit time. Therefore, automatic power adapter PCB assembly equipment is needed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic assembly device for power adapter PCB boards to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic assembly equipment for power adapter PCB boards, including a support frame, a servo motor fixedly installed on the unloading side of the support frame, and a guide assembly rotatably engaged at the center of the inside of the support frame;

[0007] The servo motor's power output end synchronously drives bevel gear two and bevel gear one to mesh and rotate via a transmission chuck. A notched chuck is fixedly engaged with the power output end of bevel gear one. A rocker arm is positioned at the upper center of the notched chuck. Bevel gear one, through the notched chuck and the rocker arm, drives the material guide assembly to intermittently rotate and feed material on the upper part of the support frame.

[0008] The adapter housing feeding assembly is fixedly installed at the feeding point of the support frame. The power adapter housing is equidistantly snapped into the inside of the adapter housing feeding assembly, and the adapter housing feeding assembly is used to feed the power adapter housing into the magazine.

[0009] The power output end of the guide assembly and the transmission shaft is fixedly connected to the power output end of the guide assembly via a coupling, and the guide assembly is used for guiding and transmission.

[0010] The assembly component is fixedly installed on the upper part of the support frame, directly opposite the guide component. PCB boards are equidistantly arranged inside the assembly component. The assembly component is used to clamp and assemble the PCB boards.

[0011] The detection component is fixedly installed on the upper part of the support frame, directly opposite the detection position after the PCB board and power adapter housing are assembled. The detection component is used for positioning and detection.

[0012] The servo motor drives the guide component and the material guide component synchronously through the transmission shaft. The material guide component positions the power adapter housing inside the adapter housing feeding component to the bottom of the assembly component through intermittent rotation. The guide component can synchronously drive the assembly component to press the internal PCB board into the power adapter housing.

[0013] Specifically, the assembly assembly includes a support bracket, a positioning groove extending through the rear of the support bracket, a flipping groove in the middle of the positioning groove for guidance, a flipping pin fixedly installed on the inner end face of the support bracket opposite the flipping groove, and a guide slide that slides up and down and engages with the inside of the support bracket. The guide slide is rotatably engaged with a support rotating seat through a support cylinder, and a positioning slider is integrally formed at the rear of the support rotating seat. Three sets of alignment slots are equidistantly opened on the lower end face of the support rotating seat. A PCB clamping assembly is provided at the upper part of the support cylinder away from the support rotating seat. A PCB board loading assembly for feeding is fixedly installed at the top of the support bracket. A connecting plate for docking is provided at the lower part of the guide slide.

[0014] The PCB board loading assembly includes a card holder for alignment, a PCB board hopper fixedly installed at the front of the card holder, and stepper motors fixedly installed on both sides of the PCB board hopper via motor mounts. The power output end of the stepper motors is provided with two sets of right-angled material blocking plates, and a proximity switch for position detection is provided near the bottom of the front face of the PCB board hopper.

[0015] The PCB clamping assembly includes a limiting seat for docking, a wide pneumatic gripper fixedly installed at the bottom of the limiting seat, four sets of linear slides elastically slidably engaged with the side of the limiting seat by a return spring, and a positioning pin fixedly installed at the center of the lower part of the linear slides. Clamps are fixedly engaged with both clamping ends of the wide pneumatic gripper, and vacuum suction cups are fixedly engaged at equal intervals on the inner end face of each clamping end near the bottom clamping end.

[0016] Specifically, the guide assembly includes a support plate, a flip guide plate that is rotatably engaged inside the support plate via a bearing seat, an alignment slide block that is slidably engaged inside the support plate via two sets of linear slide rails, and a rotating wheel fixedly disposed at the front of the flip guide plate.

[0017] Specifically, the adapter housing feeding assembly includes a swing cylinder, a cylinder rotor fixedly mounted on the power output end of the swing cylinder, and housing hoppers fixedly mounted on both sides of the cylinder rotor. Each set of housing hoppers has a pen-shaped cylinder fixedly mounted on the bottom of both sides via cylinder feet. The power output end of the pen-shaped cylinder supports and limits the power adapter housing inside the housing hopper via a baffle plate. A proximity switch for empty material detection is located at the bottom of the front face of the housing hopper.

[0018] Specifically, the detection component includes a positioning slide and a damping fixing bracket attached to the upper part of the positioning slide. An industrial inspection camera for detection is fixedly attached to the lower part of the fixing bracket, and an aperture is set at the bottom of the industrial inspection camera directly opposite the lens.

[0019] Specifically, the material guiding assembly includes a feeding turntable, a grooved wheel fixedly disposed at the center of the lower end face of the feeding turntable, four sets of locking slots opened on the side end face of the grooved wheel, and a guide shaft groove opened between two adjacent sets of locking slots. Four sets of three-axis cylinders are fixedly engaged at equal intervals on the inner end face of the feeding turntable, and the power output end of the three-axis cylinder is locked and limited by a limiting plate.

[0020] Specifically, a control box for operation is provided on the upper part of the support frame near the servo motor, and a valve island is provided on the lower end face of the support frame near the notch chuck. Positioning pin sleeves are provided at the four corners of the inner end face of the power adapter housing.

[0021] The guide slide, via the support cylinder, drives the support rotating block to move up and down within the support holder. This vertically moving support rotating block, through alignment slots and flip-up hinges, and positioning sliders and positioning grooves, drives the PCB clamping assembly to rotate within the support holder. The side of the support rotating block is fitted into the flip-up groove, which provides sufficient guidance for the rotating block's rotation, thus improving its stability. Simultaneously, the three sets of flip-up hinges, by contacting and limiting the alignment slots, drive the support rotating block to rotate laterally, facilitating adjustment of the PCB clamping assembly's clamping angle and improving the convenience of subsequent PCB clamping, loading, and pressing assembly.

[0022] Specifically, the wide-type pneumatic gripper uses two sets of clamps to hold and limit the two sides of the PCB board, and the vacuum suction cup adheres to the top of the PCB board. When a proximity switch detects the positioning of the two sets of clamps, a stepper motor drives two sets of right-angled material-resistant rotating plates to rotate 90 degrees. The upper material-resistant rotating plate limits and adheres to the PCB board, while the lower material-resistant rotating plate releases its limit on the PCB board. The upper and lower sets of material-resistant rotating plates are set at right angles, which facilitates the individual unloading of PCB boards from the PCB board hopper, improving the stability of the gripper's clamping of the PCB board.

[0023] Specifically, the flipping guide plate drives the alignment slide to move up and down inside the vertical plate via a rotating wheel, and the alignment slide drives the guide slide to move up and down inside the support bracket via a connecting plate.

[0024] The wide-type pneumatic gripper uses four sets of positioning pins to slide and fit coaxially with the positioning column sleeve, thereby positioning and pressing the PCB board into the power adapter housing, which can improve the accuracy and stability of subsequent press-fitting assembly of the PCB board and the power adapter housing.

[0025] Specifically, the bevel gear is adapted to the locking groove via a notched chuck and the guide shaft groove via a swing rod, thereby driving the grooved wheel and the feeding turntable to rotate intermittently by 90 degrees on the upper part of the support frame. The lower part of the housing hopper is closely connected to the upper part of the feeding turntable, and the upper part of the feeding turntable has a material slot for limiting the power adapter housing, which is directly opposite the opening of the adapter housing feeding assembly. This provides a sufficient positioning basis for the subsequent feeding of the power adapter housing and improves the stability of the automatic feeding of the power adapter housing.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. This invention is an integrated assembly equipment for PCB boards and power adapter housings. During the assembly of the PCB board and the power adapter housing, a servo motor can synchronously drive the material guiding component and the guide component through a transmission shaft. The material guiding component can intermittently guide the power adapter housing, while the guide component can work in conjunction with the material guiding component to synchronously drive the clamp to flip, clamp, and press the PCB board, allowing the assembly component to quickly and accurately assemble the PCB board and the power adapter housing in coordination with the material guiding component, effectively improving the efficiency of the equipment in assembling the PCB board and the power adapter housing.

[0028] 2. During transmission, the servo motor drives the material guide assembly and the guide assembly synchronously via the transmission shaft, bevel gear two, and bevel gear one. This allows the guide assembly to work in conjunction with the intermittent feeding of the feeding turntable. Furthermore, the alignment slide cyclically drives the PCB clamping assembly to clamp and feed the PCB board while simultaneously unloading and pressing the power adapter housing. This improves the stability of the equipment's assembly of the PCB board and power adapter housing, increases the efficiency of the assembly per unit time, enhances the equipment's power utilization efficiency, and reduces energy consumption.

[0029] 3. This invention is a multi-level limiting and coaxial positioning mechanism. When clamping and pressing a PCB board, the wide-type pneumatic gripper can initially clamp the side of the PCB board through the fixture. At the same time, multiple sets of vacuum suction cups can perform secondary adsorption and limiting on the upper part of the PCB board after clamping. The dual limiting structure can effectively improve the stability of the fixture locking the PCB board. Meanwhile, when pressing the PCB board and the power adapter housing, four sets of positioning pins can be coaxially guided and positioned with the positioning post sleeve inside the power adapter housing, maximizing the stability and accuracy of the fixture pressing the PCB board into the power adapter housing.

[0051] The invention will be further described below with reference to the accompanying drawings.

[0052] Example 1

[0053] Please see Figure 1-4 An embodiment of the present invention provides an automatic assembly equipment for power adapter PCB boards, including a support frame 1, a servo motor 9 fixedly installed on the unloading side of the support frame 1, and a guide assembly 6 rotatably engaged at the center of the inside of the support frame 1.

[0054] The model of servo motor 9 is MHMF022L1U2M;

[0055] The power output end of the servo motor 9 synchronously drives the bevel gear 12 and bevel gear 11 to mesh and rotate via the transmission shaft 14. The power output end of bevel gear 11 is fixedly engaged with a notched chuck 15. A rocker arm 16 is provided at the upper center of the notched chuck 15. Bevel gear 11 drives the material guide assembly 6 to intermittently rotate and feed material on the upper part of the support frame 1 through the notched chuck 15 and the rocker arm 16.

[0056] The adapter housing feeding assembly 4 is fixedly installed at the feeding position of the support frame 1. The power adapter housing 8 is equidistantly engaged inside the adapter housing feeding assembly 4, and the adapter housing feeding assembly 4 is used to feed the power adapter housing 8 into magazines.

[0057] The power output end of the guide assembly 3 and the transmission shaft 14 are fixedly connected to the power output end of the guide assembly 3 via a coupling, and the guide assembly 3 is used for guiding and transmission.

[0058] Assembly component 2 is fixedly installed on the upper part of the support frame 1, directly opposite the guide component 3, and PCB board 7 is equidistantly arranged inside the assembly component 2. Assembly component 2 is used to clamp and assemble PCB board 7.

[0059] like Figure 17 The PCB board 7 consists of a PCB board, components integrated on the PCB board, positioning holes on the upper part of the PCB board, and positioning slots on the waist side of the PCB board. The positioning holes can be easily positioned coaxially with the positioning post sleeve 17, and the positioning slots can be easily clamped and limited by the subsequent fixture 237.

[0060] The detection component 5 is fixedly installed on the upper part of the support frame 1, directly opposite the detection position after the PCB board 7 and the power adapter housing 8 are assembled. The detection component 5 is used for positioning detection.

[0061] The servo motor 9 drives the guide assembly 3 and the material guide assembly 6 synchronously through the transmission shaft 14. The material guide assembly 6 positions the power adapter housing 8 inside the adapter housing loading assembly 4 to the bottom of the assembly assembly 2 through intermittent rotation. The guide assembly 3 can synchronously drive the assembly assembly 2 to assemble and press the internal PCB board 7 into the power adapter housing 8.

[0062] like Figure 5 , Figure 6 and Figure 7 The assembly component 2 includes a support bracket 21, a positioning groove 211 extending through the rear of the support bracket 21, a flip groove 210 for guidance in the middle of the positioning groove 211, a flip pin 212 fixedly disposed on the inner end face of the support bracket 21 opposite to the flip groove 210, and a guide slide 28 slidably engaged inside the support bracket 21. Inside the guide slide 28, a support rotating seat 25 is rotatably engaged through a support cylinder 24. A positioning slider 26 is integrally formed at the rear of the support rotating seat 25. Three sets of alignment slots 27 are equidistantly disposed on the lower end face of the support rotating seat 25. A PCB clamping component 23 is disposed at the upper part of the support cylinder 24 away from the support rotating seat 25. A PCB board loading component 22 for loading is fixedly disposed at the top of the support bracket 21. A connecting plate 29 for docking is disposed at the lower part of the guide slide 28.

[0063] like Figure 8 and Figure 9 The PCB board loading assembly 22 includes a card holder 225 for alignment, a PCB board material bin 221 fixedly disposed at the front of the card holder 225, and a stepper motor 223 fixedly disposed on both sides of the PCB board material bin 221 via a motor base 222. The model of the stepper motor 223 is ZJT01-1.8-S-4-L41.

[0064] The power output end of the stepper motor 223 is equipped with two sets of right-angled material-blocking plates 224, one above the other. A proximity switch 226 for position detection is located near the bottom of the front face of the PCB board material bin 221. The model of the proximity switch 226 is E2B-S08KN04-WP-C1.

[0065] like Figure 10 and Figure 11The PCB clamping assembly 23 includes a limiting seat 231 for docking, a wide pneumatic gripper 234 fixedly disposed at the bottom of the limiting seat 231, four sets of linear slides 233 elastically slidably engaged with the side of the limiting seat 231 by a return spring 232, and a positioning pin 236 fixedly disposed at the lower center of the linear slides 233. The wide pneumatic gripper 234 is an MSQφ10 gear and rack type swing cylinder. Clamps 237 are fixedly engaged at both clamping ends of the wide pneumatic gripper 234. Vacuum suction cups 235 are fixedly engaged at equal intervals on the inner end face of each clamp 237 near the bottom clamping end.

[0066] like Figure 12 and Figure 13 The guide assembly 3 includes a support plate 33, a flip guide plate 34 that is rotatably engaged inside the support plate 33 via a bearing seat, an alignment slide block 31 that is slidably engaged inside the support plate 33 via two sets of linear slide rails 35, and a rotating wheel 32 fixedly disposed at the front of the flip guide plate 34.

[0067] like Figure 14 The adapter housing feeding assembly 4 includes a swing cylinder 45, a cylinder rotor 46 fixedly installed at the power output end of the swing cylinder 45, and housing hoppers 41 fixedly installed at both ends of the cylinder rotor 46. Each set of housing hoppers 41 has a pen-shaped cylinder 44 fixedly installed on the bottom of both sides of each set of housing hoppers 41 through a cylinder foot. The model of the pen-shaped cylinder 44 is DSN standard mini cylinder DSN-8-20-P, and the model of the swing cylinder 45 is WGY11-10-20.

[0068] Furthermore, the power output end of the pen-shaped cylinder 44 supports and limits the power adapter housing 8 inside the housing hopper 41 through the baffle plate 43. A proximity switch 2 42 for empty material detection is provided at the bottom of the front face of the housing hopper 41. The model of the proximity switch 2 42 is E2B-S08KN04-WP-C1.

[0069] like Figure 15 The detection component 5 includes a positioning slide 51 and a damping fixing bracket 54 attached to the upper part of the positioning slide 51. An industrial inspection camera 52 for inspection is fixedly attached to the lower part of the fixing bracket 54, and an aperture 53 is provided at the bottom of the industrial inspection camera 52 directly opposite the lens.

[0070] like Figure 16 The material guiding assembly 6 includes a feeding turntable 66, a grooved wheel 61 fixedly disposed at the center of the lower end face of the feeding turntable 66, four sets of locking slots 65 formed on the side end face of the grooved wheel 61, and guide shaft slots 64 formed between two adjacent sets of locking slots 65. Four sets of three-axis cylinders 62 are fixedly engaged at equal intervals on the inner end face of the feeding turntable 66. The model of the three-axis cylinders 62 is TCL20X20-S.

[0071] Furthermore, the power output end of the three-axis cylinder 62 is locked and limited by the limiting plate 63 to the power adapter housing 8.

[0072] like Figure 2 A control box 10 for operation is set on the upper part of the support frame 1 near the servo motor 9. The control box 10 is an integrated touch screen operation module, which can facilitate the automatic control of electric and start-up actuators and improve processing efficiency.

[0073] like Figure 4 A valve island 13 is provided on the lower end face of the support frame 1 near the notch chuck 15. A through groove is provided from the center of the feeding turntable 66 to the bottom. This through groove is used to connect various air pipes to the valve island 13 for easy wiring and air supply.

[0074] Positioning post sleeves 17 are provided at the four corners of the inner end face of the power adapter housing 8, which can facilitate positioning and docking with the power adapter housing 8, and also facilitate the subsequent alignment and sealing of the top cover.

[0075] like Figure 5 and Figure 7 The guide slide 28 drives the support rotating block 25 to move up and down inside the support bracket 21 via the support cylinder 24. The vertically displaced support rotating block 25 is adapted to the flipping bracket 212 through the alignment slot 27 and the positioning slider 26 is adapted to the positioning slide 211, thereby driving the PCB clamping assembly 23 to rotate 180 degrees inside the support bracket 21. The side of the support rotating block 25 is fitted and connected to the flipping slide 210. The flipping slide 210 can provide sufficient guiding foundation for the support rotating block 25 to rotate, thereby improving the stability of the support rotating block 25 to rotate. At the same time, the three sets of flipping brackets 212 can be limited by contacting the alignment slot 27, thereby driving the support rotating block 25 to rotate laterally, which facilitates the adjustment of the clamping angle of the PCB clamping assembly 23 and improves the convenience of subsequent clamping, feeding and pressing assembly of the PCB board 7.

[0076] like Figure 17 The wide-type air gripper 234 clamps and limits the two sides of the PCB board 7 through two sets of clamps 237, and the vacuum suction cup 235 adsorbs and adheres to the upper part of the PCB board 7. The clamps 237 can clamp and limit the two sides of the PCB board 7. After the clamps 237 are stable, the multiple sets of vacuum suction cups 235 can perform vacuum adsorption, further improving the stability of clamping.

[0077] When the proximity switch 226 detects the position of the two sets of clamps 237, the stepper motor 223 drives the two sets of right-angled material-blocking rotating plates 224 to rotate 90 degrees. The upper and lower sets of material-blocking rotating plates 224 are set at right angles, which can facilitate the feeding of PCB boards 7 into the PCB board material bin 221 one by one, and improve the stability of the clamps 237 in feeding and holding the PCB boards 7.

[0078] The upper resist plate 224 limits and fits the PCB board 7, while the lower resist plate 224 releases the limit on the PCB board 7, which can improve the accuracy of the resist plate 224 in feeding the PCB board 7 one by one.

[0079] like Figure 4 and Figure 13 The flip guide plate 34, through the rotating wheel 32, drives the alignment slide 31 to move up and down inside the upright plate 33. The alignment slide 31, through the connecting plate 29, synchronously drives the guide slide 28 to move up and down inside the support bracket 21. During the loading and assembly pressing of the PCB board 7, the flip guide plate 34, through the circumferential rotation of the rotating wheel 32, drives the alignment slide 31 to move up and down, thus facilitating the synchronous movement of the guide slide 28, improving the synchronization of the equipment's transmission, and also enhancing the stability of the transmission.

[0080] like Figure 2 , Figure 11 and Figure 17 The wide-type pneumatic gripper 234 slides coaxially with the positioning sleeve 17 through four sets of positioning pins 236 to position and press the PCB board 7 into the power adapter housing 8. When assembling and positioning the PCB board 7 and the power adapter housing 8, the four sets of positioning pins 236 can be positioned in advance by the clamp 237 into the four sets of positioning sleeves 17 inside the power adapter housing 8, so that the four sets of positioning sleeves 17 and the positioning pins 236 can form an axial guide limit, thereby improving the accuracy and stability of the subsequent press-fit assembly of the PCB board 7 and the power adapter housing 8.

[0081] like Figure 3 , Figure 4 and Figure 16The bevel gear 11 is adapted to the locking groove 65 via the notched chuck 15, and the rocker arm 16 is adapted to the guide shaft groove 64, thereby driving the grooved wheel 61 and the feeding turntable 66 to rotate intermittently 90 degrees on the upper part of the support frame 1. When intermittently guiding and processing the power adapter housing 8, the rocker arm 16 can be limited by sliding with the guide shaft groove 64, thereby driving the feeding turntable 66 to rotate intermittently 90 degrees, which facilitates the subsequent feeding operation of the power adapter housing 8. At the same time, the notched chuck 15 can limit and lock the feeding turntable 66 through the locking groove 65, thereby providing sufficient time for the subsequent assembly of the PCB board 7 and the power adapter housing 8 and the feeding of the next set of power adapter housings 8.

[0082] like Figure 1 and Figure 14 The lower part of the housing hopper 41 is fitted and connected to the upper part of the feeding turntable 66. The upper part of the feeding turntable 66 has a material slot for limiting the power adapter housing 8, which is directly opposite the opening of the adapter housing feeding assembly 4. The upper part of the feeding turntable 66 has four sets of material slots at equal intervals. These material slots are mainly used for receiving and positioning the power adapter housing 8. At the same time, the bottom of the housing hopper 41 is fitted with the upper part of the feeding turntable 66, which can provide a sufficient positioning base for the subsequent feeding of the power adapter housing 8 and improve the stability of the automatic feeding of the power adapter housing 8.

[0083] Working principle: such as Figure 1 and Figure 2 Before use, staff can import batches of PCB boards 7 and power adapter housings 8 into the PCB board hopper 221 and housing hopper 41 respectively, so that the PCB boards 7 can be continuously assembled into the power adapter housings 8 in the future.

[0084] like Figure 3 and Figure 4 As shown, when loading the power adapter housings 8 one by one, the operator can start the equipment through the control box 10. The servo motor 9 drives the transmission shaft 14 to rotate. When the transmission shaft 14 rotates, it can synchronously drive the bevel gear 11, the notched chuck 15, and the swing rod 16 to rotate through the bevel gear 2 12. At this time, the swing rod 16 can slide and limit the guide shaft groove 64, thereby driving the grooved wheel 61 and the loading turntable 66 to rotate 90 degrees, so that the material groove on the upper part of the loading turntable 66 is directly opposite the bottom of the housing hopper 41. When the material groove on the upper part of the loading turntable 66 is in place, the power adapter housings 8 inside the housing hopper 41 can fall into the material groove under the action of gravity. Figure 16The three-axis cylinder 62 at the corresponding material trough can limit and lock the power adapter housing 8 in the material trough through the limit plate 63, and complete the feeding operation of the power adapter housing 8. When the power adapter housing 8 inside the housing hopper 41 is fed, the proximity switch 42 detects that the housing hopper 41 is empty. At this time, the proximity switch 42 can transmit an electrical signal to the control box 10. The control box 10 can start the solenoid valve corresponding to the valve island 13 through the internal PLC, so that the swing cylinder 45 can drive the housing hopper 41 to rotate through the cylinder rotating seat 46. At the same time, the two sets of pen-shaped cylinders 44 can seal the bottom of the empty housing hopper 41 to facilitate the subsequent replenishment of the power adapter housing 8. The new set of housing hoppers 41 can rotate to the upper part of the guide assembly 6 again. At the same time, the two sets of pen-shaped cylinders 44 release the limit on the inside of the power adapter housing 8 through the baffle plate 43.

[0085] like Figure 3 , Figure 4 and Figure 13 The aforementioned transmission shaft 14, while providing power to guide the material to the material guiding assembly 6 via the bevel gear 12, can also synchronously drive the tilting guide plate 34 to rotate via a coupling. When the tilting guide plate 34 rotates, it can synchronously drive the alignment slide 31 to move up and down cyclically via the rotating wheel 32. This allows the alignment slide 31 to synchronously drive the guide slide 28 to move up and down within the support base 21 via the connecting plate 29. Figure 7 , Figure 8 and Figure 10 When the connecting plate 29 moves from bottom to top, the aforementioned swing rod 16 pushes the feeding turntable 66 to rotate through the guide shaft groove 64, and at the same time, the aforementioned connecting plate 29 can drive the PCB clamping assembly 23 to flip and pick up the PCB board 7 through the support cylinder 24.

[0086] like Figure 5 and Figure 7When the guide slide 28 drives the support rotating seat 25 to move from bottom to top, the initial positioning groove 211 and the positioning slider 26 slide together, which can drive the support rotating seat 25 to move vertically upward. When the alignment slot 27 on the upper part of the support rotating seat 25 encounters the flipping pin 212, the flipping pin 212 can be limited by the three sets of alignment slots 27, thereby driving the support rotating seat 25 to flip 180 degrees along the flipping groove 210. At this time, the positioning slider 26 at the bottom of the support rotating seat 25 is facing upward. When the flipping pin 212 disengages from the alignment slot 27, the flipping groove 210 can guide the positioning slider 26 into the upper positioning groove 211 through the arc-shaped limit, so that the support rotating seat 25 can move upward in a straight line when flipped to the upper part. At the same time, the above flipping steps can drive the PCB clamping assembly 23 to flip 180 degrees from bottom to top. Then, it aligns directly with the bottom of the PCB board hopper 221. As the guide slide 28 continues to rise, the support rotary seat 25 can drive the PCB clamping assembly 23 to be positioned at the bottom of the PCB board hopper 221 via the support cylinder 24. Subsequently, the limiting seat 231 can drive the two sets of clamps 237 to be positioned at the bottom of the PCB board 7 in the PCB board hopper 221. The four sets of positioning pins 236 can be positioned in the positioning holes inside the PCB board 7. These positioning holes are used to position with the positioning post sleeve 17 inside the power adapter housing 8. Then, the two sets of clamps 237 can be positioned in the positioning slots on the side of the PCB board 7. At this time, the wide-type pneumatic gripper 234 can clamp the side of the PCB board 7 through the two sets of clamps 237. At the same time, the multiple sets of vacuum suction cups 235 inside the clamps 237 can perform vacuum adsorption on the upper surface of the PCB board 7, completing the double clamping operation of the PCB board 7. Figure 6 and Figure 8 The proximity switch 226 can synchronously detect the positioning of the clamp 237, and then transmit an electrical signal to the control box 10. The control box 10 can then start the stepper motor 223, which can drive the two sets of resistive rotating plates 224 to rotate 90 degrees. At this time, the lower resistive rotating plate 224 is in the state of blocking the PCB board 7, and the upper resistive rotating plate 224 is in the state of being released from the limit. When the two sets of resistive rotating plates 224 rotate 90 degrees, the lower resistive rotating plate 224 is released from the limit. Plate 224 releases the restriction on PCB board 7, while the upper resisting plate 224 restricts the second set of PCB boards 7. At the same time, the guide slide 28 can drive the PCB board 7 out of the PCB board material bin 221 through the clamp 237. When the proximity switch 226 detects that the clamp 237 has disengaged, the stepper motor 223 continues to drive the two sets of resisting plates 224 to rotate 90 degrees, so that the bottom PCB board 7 still falls to the opening of the PCB board material bin 221.

[0087] As the guide slide 28 moves downward, the aforementioned loading turntable 66 moves the power adapter housing 8 to a position directly below the PCB board 7 held by the clamp 237. Simultaneously, after the aforementioned flipping step, the PCB board 7 held by the clamp 237 is aligned directly with the power adapter housing 8. Then, the four sets of positioning pins 236 are rigidly positioned into the four sets of positioning sleeves 17 inside the power adapter housing 8, completing coaxial guiding positioning. Subsequently, the two sets of clamps 237 move the PCB board 7 to press and assemble it into the power adapter housing 8. At this point, the PCB... The PCB 7 can be positioned outside the positioning post sleeve 17 inside the power adapter housing 8 through four sets of internal positioning holes, thereby completing the assembly operation between the PCB 7 and the power adapter housing 8. After pressing, multiple sets of vacuum suction cups 235 break the vacuum, and at the same time, the wide-type air gripper 234 drives the clamp 237 to separate from the PCB 7. At this time, the guide slide 28 again drives the clamp 237 to move upward. During the pressing assembly of the PCB 7 and the power adapter housing 8, the notched chuck 15 and the locking groove 65 are in the rotation limit stage to improve the stability of pressing. Subsequently, as... Figure 2 and Figure 5 The aforementioned loading turntable 66 drives the assembled PCB board 7 and power adapter housing 8 to the bottom of the industrial inspection camera 52. At this time, the industrial inspection camera 52 can take pictures of the PCB board 7 and power adapter housing 8 for inspection, which facilitates the subsequent determination of whether the assembly is qualified. Then, the loading turntable 66 drives the inspected PCB board 7 and power adapter housing 8 to the unloading position, and the external robotic arm module can unload the PCB board 7 and power adapter housing 8.
