Description

Technical Field

[0001] This invention relates to the field of power adapter equipment technology, specifically to an automated assembly device for power adapter processing. Background Technology

[0002] A power adapter is an electronic device that converts alternating current (AC) into direct current (DC). It connects to a power outlet via a plug and supplies power to devices via a data cable. It can provide stable voltage and current to devices such as mobile phones, laptops, and routers. When manufacturing a power adapter, the power adapter casing needs to be assembled with a PCB board to improve the production efficiency of the power adapter.

[0003] For example, CN112917123B discloses an automated assembly device for power adapter processing, relating to the field of power adapter processing technology. This automated assembly device includes a first conveyor belt and a second conveyor belt. A first conveyor plate is mounted on the top of the first conveyor belt, and a rotating shaft is connected to the top of the first conveyor plate. A fixed plate is mounted on the top of the rotating shaft, and a lower plate is mounted on the top of the fixed plate. A support column is provided on the outer right side of the first conveyor belt. In this automated assembly device, the operation of a second motor enables a first cylinder to drive a first suction cup to rotate, thereby causing the rotating shaft to change the direction of the fixed plate. This allows the direction of the lower plate on top of the fixed plate to also be changed. By resetting the direction of the lower plate, the situation where the PCB board cannot be installed with the lower plate due to incorrect orientation when the lower plate is placed on the fixed plate can be avoided.

[0004] While the aforementioned equipment can assemble PCB boards and power adapter housings, its reliance on flexible conveyor belts for loading both components results in insufficient accuracy and stability in the repetitive loading and positioning process. Furthermore, the lack of rigid limits on the loading mechanism further impacts the precision of loading and processing positioning. Additionally, the equipment lacks the convenience for simultaneously unloading semi-finished power adapters after PCB assembly, reducing its practicality. Therefore, an automated assembly system for power adapter processing is needed to address these issues. Summary of the Invention

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

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automated assembly equipment for processing power adapters, comprising a support plate, two sets of guide slides are provided on the upper part of the support plate, an adjustable stroke cylinder is provided at the center of the upper end face of the guide slides, and a cylinder slide is provided at the output end of the adjustable stroke cylinder;

[0007] An aluminum profile frame for support is fixedly mounted on the lower end face of the bearing plate, and foot cups are provided at the four corners of the lower end face of the aluminum profile frame. Heavy-duty casters are provided on the lower end face of the aluminum profile frame near the foot cups.

[0008] A reciprocating feeding device is fixedly installed at the middle of the upper end face of the support plate, and a power adapter housing is equidistantly slidably installed on the inner end face of the reciprocating feeding device. The reciprocating feeding device is used to alternately reciprocate feeding the power adapter housing.

[0009] As shown in the figure, the rotary module is preferably a rack and pinion type swing cylinder. The rack and pinion transmission structure can provide a large output torque for this equipment, thereby improving the stability of the rotary module driving the flipping chuck to swing 180 degrees.

[0010] The rotary module is fixedly installed at the center of the lower end face of the cylinder slide, and a flip-up bracket is fixedly installed at the lower part of the rotary module.

[0011] The adsorption pressing device comprises two sets, each set positioned below the flip-up card holder. A PCB board is adsorbed and mounted at the bottom of the adsorption pressing device.

[0012] The PCB board is the bottom housing assembly of the power adapter. It includes the housing, the pads in the middle, and the mating posts around the pads. When assembling the PCB board and the power adapter housing, the external multi-axis welding robot arm can perform welding simultaneously while the vacuum suction cup presses the PCB board, making the assembly process more integrated and improving the efficiency and speed of assembling the PCB board and the power adapter housing.

[0013] The adsorption pressing device is used to adsorb and load the PCB board for assembly, and the adsorption pressing device is used to simultaneously clamp and unload the assembled PCB board and the power adapter housing.

[0014] Preferably, the reciprocating feeding device includes a linear displacement module, which is preferably a magnetic couple rodless cylinder. This can effectively reduce the space occupied by the output module, and the point-to-point output can also improve the stability of feeding and transferring the feeding guide. The linear displacement module can also be selected as a lead screw module or a linear motor.

[0015] A feeding bin is provided at the upper center of the linear displacement module, and a cylinder slide is slidably arranged inside the linear displacement module. A floating bracket is provided on top of the cylinder slide, and a feeding guide is slidably arranged on the cylinder slide through the positioning socket.

[0016] Limiting blocks are provided at the four corners of the upper end face of the feeding guide, and two sets of linear slide rails are slidably engaged at the bottom of the feeding guide. A floating bracket is provided at the center of the lower end face of the feeding guide. Two sets of pressing slots are opened on the upper end face of the feeding guide. A feeding chamfer is opened at the opening of the pressing slot. The feeding chamfer can facilitate the quick and stable insertion of the power adapter housing into the pressing slot by the unloading bin, thereby improving the convenience and stability of unloading.

[0017] Furthermore, a positioning step is provided at the center of the inner end face of the press-fit slot, and two sets of positioning slide grooves are provided in the width direction of the press-fit slot. The two sets of positioning slide grooves can facilitate the subsequent provision of sufficient guiding foundation for the contouring fixture, and improve the stability of limiting the assembled power adapter housing.

[0018] Both ends of the linear displacement module are threaded with blocking bolts. A first slotted photoelectric switch is provided at the center and both sides of the side end face of the linear displacement module. A first baffle is provided at the center of the side end face of the cylinder slide.

[0019] Preferably, the adsorption pressing device includes a support bracket, a driven gear is rotatably engaged at the center of the inner end face of the support bracket, and two sets of arc-shaped guide grooves are provided on the inner end face of the driven gear. A guide roller is slidably arranged on the driven gear through the arc-shaped guide grooves. A linear slider is provided at the bottom of the guide roller, and a contour clamp is fixedly provided on the lower end face of the linear slider. A suction cup guide seat is provided at the center of the inner end face of the support bracket, and vacuum suction cups are provided at the four corners of the lower end face of the suction cup guide seat.

[0020] A positioning bracket is provided at the center of the upper end face of the support bracket, and a servo motor is provided near the corner of the inner end face of the support bracket. A drive gear is provided at the output end of the servo motor. A stroke groove is provided near the middle of the inner end face of the support bracket. A second slotted photoelectric switch is provided on both sides of the upper end face of the support bracket, directly opposite the stroke groove. A second baffle is provided on the upper end face of the driven gear, directly opposite the stroke groove. Two sets of linear grooves are provided in the middle of the upper end face of the support bracket, and linear slides are provided on the lower end face of the support bracket, directly opposite the two sets of linear grooves.

[0021] Preferably, the power adapter housing is equidistantly slidably engaged with the inner end face of the feeding hopper, and the opening of the lower end face of the feeding hopper is fitted and connected to the upper end face of the feeding guide. The opening of the feeding hopper is the same size as the pressing slot, which can effectively improve the stability of the subsequent feeding hopper feeding material into the pressing slot. At the same time, the fit between the feeding guide and the feeding hopper facilitates the subsequent feeding hopper to feed material into the pressing slot inside the feeding guide one by one, thus improving the accuracy of feeding.

[0022] Preferably, the side of the feeding guide is connected to the side wall of the unloading bin via the limiting block, and the blocking bolt is connected to the outer wall of the cylinder slide. The three sets of first slot-shaped photoelectric switches are all directly opposite the center of the cylinder slide. The three sets of first slot-shaped photoelectric switches are located at the left and right limits and the origin of the side of the linear displacement module, respectively, which facilitates the detection and positioning of the movement position of the cylinder slide and improves the accuracy of the cylinder slide in feeding the power adapter housing. The dual rigid limiting of the limiting block and the blocking bolt can effectively improve the accuracy of feeding and guiding the feeding guide. The rigid limiting and photoelectric detection of the first slot-shaped photoelectric switches can maximize the accuracy of the subsequent positioning of the unloading bin, the pressing slot, the adsorption pressing device, and the power adapter housing.

[0023] Preferably, the inner wall of the press-fit groove is fitted to the side wall of the power adapter housing, and the inner end face of the press-fit groove supports the bottom of the power adapter housing through the positioning step. The bottom of the power adapter housing does not contact the bottom of the press-fit groove. The floating bracket and the positioning socket are slidably engaged. The positioning step provides stable support for the bottom of the power adapter housing, so that the bottom of the power adapter housing and the press-fit groove have a ground clearance. This provides sufficient guiding foundation for the subsequent clamping of the side of the power adapter housing by the contour jig, improving the convenience of limiting the power adapter housing. The floating bracket and the positioning socket can be relatively displaced, which can compensate for the relative displacement of the linear displacement module and the feeding guide, preventing the feeding guide and the linear displacement module from shifting after long-term use, thus affecting the service life of the linear displacement module.

[0024] Preferably, the side of the driving gear meshes with the driven gear, the width of the arc-shaped guide groove is equal to the diameter of the guide roller, the contouring fixture is L-shaped and has an alignment chamfer at the end of the contouring fixture, which facilitates quick and easy alignment and positioning of the side of the power adapter housing. The guide roller is rolled inside the arc-shaped guide groove, which reduces friction and improves transmission efficiency and accuracy.

[0025] Preferably, the contouring clamp is adapted to the arc-shaped guide groove via the guide roller, and the linear slider is adapted to the linear slide block, thereby slidably engaging with the bottom of the support bracket. The contouring clamp is slidably connected to the inside of the feeding guide block via the positioning slide groove. The centripetal and centrifugal displacements of the two sets of contouring clamps can facilitate quick and convenient subsequent limiting of the power adapter housing, improving the stability of locking the power adapter housing.

[0026] Preferably, the middle of both sets of the second slot-shaped photoelectric switches is directly opposite the second baffle, the bottom of the four sets of vacuum suction cups is attached and adsorbed to the upper surface of the PCB board, and the two sets of contouring clamps are attached to the side wall of the power adapter housing. This can effectively improve the stability of the unloading and limiting of the assembled power adapter housing. The second slot-shaped photoelectric switches can rotate synchronously when the driven gear rotates. The two sets of second slot-shaped photoelectric switches can limit and detect the rotation angle of the driven gear, preventing the subsequent contouring clamp from exceeding the limit when limiting and clamping the power adapter housing, thus improving the protection and accuracy of clamping the power adapter housing.

[0027] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0028] 1. This invention, by setting up a reciprocating feeding device for reciprocating displacement feeding and an adsorption pressing device for alternating feeding and pressing, enables the linear displacement module to perform reciprocating clip feeding by driving the feeding guide seat. At the same time, the adsorption pressing device can assemble the PCB board into the power adapter housing inside the feeding guide seat without interruption under the drive of the stroke adjustable cylinder. The multi-station, uninterrupted setting can effectively improve the efficiency of the equipment in assembling the PCB board and the power adapter housing, and also improve the automation level of the equipment.

[0029] 2. This invention incorporates a first slotted photoelectric switch, a blocking bolt, and a limiting block. Both the blocking bolt and the limiting block are rigid limiting mechanisms. The blocking bolt limits the forward movement of the feeding guide, while the limiting block limits the rear of the feeding guide. The first slotted photoelectric switch accurately detects the position of the feeding guide. The detection of both rigid and flexible limits effectively improves the accuracy of the feeding guide's placement and positioning during feeding and alignment assembly, thereby enhancing the precision of subsequent PCB board and power adapter housing assembly.

[0030] 3. By incorporating an adsorption and pressing device, this invention enables multiple sets of vacuum suction cups to perform omnidirectional adsorption and loading operations on the exterior of the PCB board during the assembly and unloading of the PCB board and power adapter housing. Simultaneously, after assembly, the contouring fixture can clamp and unload the assembled PCB board and power adapter housing at the same time, effectively improving the stability and convenience of the equipment in assembling and unloading the PCB board and power adapter housing. It also enhances the functional integration of the equipment and reduces its footprint.

[0031] 4. By setting a second baffle and a second slotted photoelectric switch, when the power adapter housing is being locked and unloaded, the driven gear can rotate under the drive of the driving gear. At the same time, the driven gear can drive the second baffle to rotate synchronously. The two sets of second slotted photoelectric switches can provide real-time feedback based on the centripetal and centrifugal strokes of the two sets of contour jigs, thereby detecting the second baffle in real time and opening and closing the locking servo motor. This effectively improves the stability and accuracy of the contour jig clamping and locking the power adapter housing.

[0032] 5. The floating bracket and positioning socket of the present invention, when docking the feeding guide and the linear displacement module, the floating bracket and the positioning socket are in non-rigid floating contact, which can provide sufficient compensation space for docking and guiding the linear displacement module and the feeding guide, effectively improving the stability of the feeding guide in reciprocating operation, and also improving the subsequent service life of the linear displacement module.

[0055] The invention will be further described below with reference to the accompanying drawings.

[0056] Example 1

[0057] Please see Figure 1-18An embodiment of the present invention provides an automated assembly equipment for processing power adapters, including a support plate 5, two sets of guide slides 8 are provided on the upper part of the support plate 5, a stroke adjustable cylinder 10 is provided at the center of the upper end surface of the guide slide 8, and a cylinder slide 11 is provided at the output end of the stroke adjustable cylinder 10.

[0058] An aluminum profile frame 7 for support is fixedly installed on the lower end face of the bearing plate 5, and foot cups 6 are provided at the four corners of the lower end face of the aluminum profile frame 7. Heavy-duty casters 12 are provided on the lower end face of the aluminum profile frame 7 near the foot cups 6.

[0059] The reciprocating feeding device 3 is fixedly installed at the middle of the upper end face of the bearing plate 5, and the power adapter housing 2 is equidistantly slidably installed on the inner end face of the reciprocating feeding device 3. The reciprocating feeding device 3 is used to alternately reciprocate feeding the power adapter housing 2.

[0060] like Figure 6 The rotary module 13 is preferably a rack and pinion type swing cylinder. The rack and pinion transmission structure can provide a large output torque for this equipment, thereby improving the stability of the rotary module 13 driving the flipping chuck 9 to swing 180 degrees.

[0061] The rotary module 13 is fixedly installed at the center of the lower end face of the cylinder slide 11, and a flip-up bracket 9 is fixedly installed at the lower part of the rotary module 13.

[0062] The adsorption pressing device 4 has two sets, and the two sets of adsorption pressing devices 4 are respectively located at the lower part of the flip-out card holder 9. The PCB board 1 is adsorbed and placed at the bottom of the adsorption pressing device 4.

[0063] PCB board 1 is the bottom housing assembly of the power adapter, which includes a housing, a pad in the middle, and mating posts around the pad. When assembling PCB board 1 and power adapter housing 2, the external multi-axis welding robot arm can perform welding simultaneously while the vacuum suction cup 412 presses PCB board 1, making the assembly process more integrated and improving the efficiency and speed of assembling PCB board 1 and power adapter housing 2.

[0064] The adsorption pressing device 4 is used to adsorb and load the PCB board 1 for assembly, and the adsorption pressing device 4 is used to simultaneously clamp and unload the assembled PCB board 1 and the power adapter housing 2.

[0065] like Figure 7 , Figure 8 , Figure 9 and Figure 10The reciprocating feeding device 3 includes a linear displacement module 32. The linear displacement module 32 is preferably a magnetic couple rodless cylinder, which can effectively reduce the space occupied by the output module and improve the stability of feeding and transferring the material to the feeding guide 38 through point-to-point output. The linear displacement module 32 can also be selected as a lead screw module or a linear motor.

[0066] A feeding bin 36 is provided at the upper center of the linear displacement module 32, and a cylinder slide block 311 is slidably provided inside the linear displacement module 32. A floating bracket 314 is provided on the top of the cylinder slide block 311, and a feeding guide block 38 is slidably provided on the cylinder slide block 311 through the positioning socket 315.

[0067] Limiting blocks 35 are provided at the four corners of the upper end face of the feeding guide 38, and two sets of linear slide rails 31 are slidably engaged at the bottom of the feeding guide 38. A floating bracket 314 is provided at the center of the lower end face of the feeding guide 38. Two sets of pressing slots 37 are opened on the upper end face of the feeding guide 38. A feeding chamfer 313 is opened at the opening of the pressing slot 37. The feeding chamfer 313 can facilitate the unloading bin 36 to quickly and stably guide the power adapter housing 2 into the pressing slot 37, thereby improving the convenience and stability of unloading.

[0068] Furthermore, a positioning step 39 is provided at the center of the inner end face of the press-fit slot 37, and two sets of positioning slides 310 are provided in the width direction of the press-fit slot 37. The two sets of positioning slides 310 can provide sufficient guiding foundation for the contour jig 411 in the future, and improve the stability of limiting the assembled power adapter housing 2.

[0069] Both ends of the linear displacement module 32 are threaded with blocking bolts 34. A first slotted photoelectric switch 33 is provided in the middle and on both sides of the side end face of the linear displacement module 32. A first baffle 312 is provided at the center of the side end face of the cylinder slide 311.

[0070] like Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 The adsorption pressing device 4 includes a support base 47. A driven gear 44 is rotatably engaged at the center of the inner end face of the support base 47. Two sets of arc-shaped guide grooves 415 are provided on the inner end face of the driven gear 44. A guide roller 414 is slidably arranged on the driven gear 44 through the arc-shaped guide grooves 415. A linear slider 49 is provided at the bottom of the guide roller 414. A contour clamp 411 is fixedly arranged on the lower end face of the linear slider 49. A suction cup guide seat 416 is provided at the center of the inner end face of the support base 47. Vacuum suction cups 412 are provided at the four corners of the lower end face of the suction cup guide seat 416.

[0071] A positioning bracket 41 is provided at the center of the upper end face of the support bracket 47, and a servo motor 42 is provided near the corner of the inner end face of the support bracket 47. A drive gear 410 is provided at the output end of the servo motor 42. A stroke groove 48 is provided near the middle of the inner end face of the support bracket 47. A second slotted photoelectric switch 46 is provided on both sides of the upper end face of the support bracket 47 opposite to the stroke groove 48. A second baffle 45 is provided on the upper end face of the driven gear 44 opposite to the stroke groove 48. Two sets of linear grooves 43 are provided in the middle of the upper end face of the support bracket 47, and linear slide blocks 413 are provided on the lower end face of the support bracket 47 opposite to the two sets of linear grooves 43.

[0072] like Figure 7 The power adapter housing 2 is equidistantly slidably snapped onto the inner end face of the feeding bin 36, which facilitates the continuous supply of raw materials to the pressing slot 37 inside the feeding guide seat 38 for feeding.

[0073] The lower end opening of the feeding bin 36 is fitted and connected to the upper end of the feeding guide 38. The opening of the feeding bin 36 is the same size as the pressing slot 37, which can effectively improve the stability of the feeding bin 36 feeding the pressing slot 37. At the same time, the fit between the feeding guide 38 and the feeding bin 36 makes it convenient for the feeding bin 36 to feed the pressing slots 37 inside the feeding guide 38 one by one, thus improving the accuracy of feeding.

[0074] like Figure 7 and Figure 11 The side of the feeding guide seat 38 is connected to the side wall of the unloading bin 36 through the limiting block 35, and the blocking bolt 34 is connected to the outer wall of the cylinder slide 311. The double rigid limiting of the limiting block 35 and the blocking bolt 34 can effectively improve the accuracy of feeding and guiding the feeding guide seat 38. The rigid limiting and the photoelectric detection of the first slot-type photoelectric switch 33 can maximize the accuracy of the subsequent positioning of the unloading bin 36, the pressing slot 37, the adsorption pressing device 4, and the power adapter housing 2.

[0075] like Figure 8 The three sets of first slot type photoelectric switches 33 are all directly opposite the middle of the cylinder slide 311. The three sets of first slot type photoelectric switches 33 are located at the left and right limits and the origin of the linear displacement module 32, respectively, which facilitates the detection and positioning of the movement position of the cylinder slide 311 and improves the accuracy of the cylinder slide 311 in feeding the power adapter housing 2.

[0076] like Figure 7 and Figure 9The inner wall of the press-fit groove 37 is fitted and connected to the side wall of the power adapter housing 2, and the inner end face of the press-fit groove 37 supports the bottom of the power adapter housing 2 through the positioning step 39. The bottom of the power adapter housing 2 does not contact the bottom of the press-fit groove 37. The positioning step 39 can provide stable support for the bottom of the power adapter housing 2, so that the bottom of the power adapter housing 2 and the bottom of the press-fit groove 37 have a ground clearance, thereby providing a sufficient guiding foundation for the subsequent clamping of the side of the power adapter housing 2 by the contour jig 411, and improving the convenience of limiting the power adapter housing 2.

[0077] like Figure 13 The floating bracket 314 and the positioning socket 315 are slidably engaged, and the floating bracket 314 and the positioning socket 315 can be relatively displaced. This can compensate for the relative displacement of the linear displacement module 32 and the feeding guide 38, and prevent the feeding guide 38 from shifting away from the linear displacement module 32 after long-term use, thus affecting the service life of the linear displacement module 32.

[0078] like Figure 18 The side of the driving gear 410 meshes with the driven gear 44. The width of the arc-shaped guide groove 415 is equal to the diameter of the guide roller 414. The guide roller 414 is rolled inside the arc-shaped guide groove 415, which can reduce friction and improve transmission efficiency and accuracy.

[0079] The contour clamp 411 is L-shaped, and a chamfer is provided at the end of the contour clamp 411 to facilitate quick and easy alignment and positioning of the side of the power adapter housing 2.

[0080] like Figure 17 and Figure 18 The contouring fixture 411 is adapted to the arc-shaped guide groove 415 via the guide roller 414 and the linear slider 49 is adapted to the linear slide block 413, and thus slides and engages at the bottom of the support bracket 47. The contouring fixture 411 is slidably connected to the inside of the feeding guide 38 via the positioning slide groove 310. The centripetal and centrifugal displacements of the two sets of contouring fixtures 411 can facilitate the subsequent quick and convenient limiting of the power adapter housing 2, and improve the stability of locking the power adapter housing 2.

[0081] like Figure 16 The middle of both sets of second slot-shaped photoelectric switches 46 is directly opposite the second baffle 45. The second slot-shaped photoelectric switches 46 can rotate synchronously when the driven gear 44 rotates. The two sets of second slot-shaped photoelectric switches 46 can limit and detect the rotation angle of the driven gear 44, preventing the subsequent contouring fixture 411 from exceeding the limit when clamping the power adapter housing 2, thus improving the protection and accuracy of clamping the power adapter housing 2.

[0082] like Figure 4 The bottom of the four sets of vacuum suction cups 412 are attached to the upper surface of the PCB board 1 for adsorption connection, and the two sets of contour clamps 411 are attached to the side wall of the power adapter housing 2, which can effectively improve the stability of the unloading limit of the assembled power adapter housing 2.

[0083] Working principle: Before use, the operator can guide multiple sets of power adapter housings 2 of the PCB boards to be assembled 1 into the unloading hopper 36 through the external transfer module. Initially, as shown... Figure 10 As shown, at this time, the feeding guide seat 38 is at its left extreme position, and simultaneously... Figure 11 As shown, the blocking bolt 34 on the left side is engaged with the cylinder slide 311, while the limiting block 35 on the right side is engaged with the left side of the unloading bin 36. At this time, the power adapter housing 2 inside the unloading bin 36 can fall directly into the pressing slot 37 on the right side. Figure 9 When the power adapter housing 2 falls into the pressing slot 37 under the guidance of the unloading bin 36, the positioning step 39 can support the bottom of the power adapter housing 2, so that the upper part of the power adapter housing 2 is flush with the upper surface of the loading guide 38. At the same time, the positioning step 39 can also provide space for the bottom of the power adapter housing 2, which is convenient for the subsequent clamping and unloading of the contour jig 411. Meanwhile, at this time, the bottom of the two sets of vacuum suction cups 412 on the right side is adsorbed with PCB board 1, which is convenient for subsequent assembly with the power adapter housing 2.

[0084] like Figure 1 , Figure 2 and Figure 7 When assembling the PCB board 1 and the power adapter housing 2, the linear displacement module 32 is activated. At this time, the linear displacement module 32 drives the cylinder slide 311 to move from inside the unloading bin 36 to the outside. Meanwhile, the loading guide 38 on the right side is loading power adapter housings 2. Simultaneously, as the loading guide 38 moves outward, its upper part limits the bottom of the previous group of power adapter housings 2, allowing the loading guide 38 to load the power adapter housings 2 inside the unloading bin 36 one by one. When the cylinder slide 311 drives the loading guide 38 and the power adapter housing 2 to the bottom of the adsorption pressing device 4 at the pressing station, at this time... Figure 8 , Figure 11The first baffle 312 on the side of the cylinder slide 311 can be positioned inside the first slotted photoelectric switch 33. At the same time, the blocking bolt 34 located there can limit the tail of the cylinder slide 311, and the limiting block 35 on the empty material side can limit the rear of the unloading bin 36. The double rigid limiting can make the pressing slot 37 face the adsorption pressing device 4. At this time, when the first slotted photoelectric switch 33 senses the first baffle 312, the first slotted photoelectric switch 33 can activate the stroke adjustable cylinder 10. The stroke adjustable cylinder 10 can drive the cylinder slide 11, the flipping slot 9 and the two sets of adsorption pressing devices 4 to move down synchronously, as shown in the figure. As the adsorption pressing device 4 moves down, the four sets of vacuum suction cups 412 can drive the PCB board 1 adsorbed at the bottom to be pressed into the power adapter housing 2 inside the pressing slot 37, thus completing the pressing assembly operation of the PCB board 1 and the power adapter housing 2.

[0085] When simultaneously unloading the assembled PCB board 1 and power adapter housing 2, such as Figure 4 and Figure 17 At this time, when the two sets of contouring clamps 411 fall, they can simultaneously fall into the two sets of positioning slides 310 on the side of the pressing slot 37. When the vacuum suction cup 412 drives the PCB board 1 to be completely pressed into the power adapter housing 2, the four sets of vacuum suction cups 412 break the vacuum and simultaneously... Figure 18 The servo motor 42 drives the drive gear 410 to rotate, which in turn drives the driven gear 44 to mesh and rotate. The driven gear 44 is slidably connected to the guide roller 414 via the arc-shaped guide groove 415, thereby driving the two sets of 419 to slide radially within the linear slide block 413. This allows the two sets of linear sliders 49 to drive the contour jig 411 to limit the side wall of the power adapter housing 2 after the PCB board 1 is assembled within the positioning groove 310. When clamping and unloading the PCB board 1, if... Figure 14 and Figure 16 At this time, second slotted photoelectric switches 46 are provided on both sides of the travel groove 48, corresponding to the extreme positions of the outward movement and clamping of the contour jig 411, respectively. This prevents the contour jig 411 from over-clamping the power adapter housing 2. The second slotted photoelectric switch 46 can detect the position of the second baffle 45 in real time during operation. When the driven gear 44 drives the contour jig 411 to clamp the power adapter housing 2, the second baffle 45 can rotate synchronously with the driven gear 44. When the contour jig 411 clamps the side wall of the power adapter housing 2, the second slotted photoelectric switch 46 can detect the position of the second baffle 45, thereby locking the servo motor 42, thus completing the unloading and locking operation of the power adapter housing 2. Then, as in 5 and Figure 6After the second slotted photoelectric switch 46 locks the servo motor 42, it can synchronously start the adjustable cylinder 10 to reset, so that the two sets of contouring clamps 411 can hold the assembled PCB board 1 and power adapter housing 2 away from the pressing slot 37. Then the rotary module 13 starts and can swing 180 degrees, so that the assembled PCB board 1 and power adapter housing 2 are away from the pressing slot 37. At the same time, a new set of vacuum suction cups 412 that have completed adsorption are moved to the upper part of the pressing slot 37 again, and the cycle repeats.
