Description

TECHNICAL FIELD

[0002] With the increasing demand for intelligence, the dust collector needs to have multiple functions such as automatic navigation, intelligent obstacle avoidance, dust detection, and interaction with users, while achieving performance optimization and compact structure. However, ordinary circuit boards are difficult to meet the requirements, so it is necessary to design customized circuit boards. Customized circuit boards can be designed according to specific functional requirements, integrating various sensors, controllers, and communication modules, etc., so that the dust collector can perceive the surrounding environment and make corresponding actions. Customized circuit boards include detection and assembly processes in the production process. During detection, the circuit board needs to be positioned first, and then tested by a test device with multiple probes. Since multiple probes need to match the circuits on the circuit board, the positioning accuracy of the circuit board is required to be high. During assembly, the circuit board needs to be installed at a specified position, so accurate positioning is also required.

[0039] Further, please refer to Figure 7 , the inner wall of the slider 63 is rotatably installed with a first screw rod 611, the bottom surface of the mounting box 66 is fixedly connected with a first nut block 610, the first nut block 610 is threadedly connected with the first screw rod 611, the operator can rotate the first screw rod 611 with a screwdriver, when the first screw rod 611 rotates, it can drive the mounting box 66 to slide on the slider 63 through the first nut block 610 by the thread connection principle, so as to adjust the position of the mounting box 66 on the slider 63, so that the operator can adjust the position of the four mounting boxes 66 in advance according to the length and width of the rectangular circuit board to be positioned, so that the four sets of clamping pieces 69 are more suitable for the edges of the rectangular circuit board.

[0040] In addition, please refer to Figure 2 、 Figure 9 - Figure 11 , the positioning and clamping assembly 6 further comprises a locking portion 7 for switching between elastic clamping and rigid clamping, the locking portion 7 comprises a cross-shaped frame 71 which is vertically slidably connected to the top surface of the annular frame 5, the center portion of the cross-shaped frame 71 is fixedly connected with a second nut block 72, a second screw rod 73 is rotatably installed on the annular frame 5, and a locking strip 77 is slidably connected through the bottom of the mounting box 66; the locking portion 7 further comprises a bevel gear ring 74, a bevel gear rod 75 and four support strips 76, the second screw rod 73 is threadedly connected with the second nut block 72, the bevel gear ring 74 is fixedly connected to the outer wall of the second screw rod 73, the bevel gear rod 75 is rotatably installed on the annular frame 5, the bevel gear rod 75 is engaged with the bevel gear ring 74, the four support strips 76 are respectively fixedly connected to the top inner walls of the four mounting boxes 66, the support strips 76 are in sliding contact with the extension sections of the plurality of elastic expansion rods 67 in the mounting boxes 66, the friction between the support strips 76 and the extension sections of the elastic expansion rods 67 is small, the support strips 76 mainly play a supporting role, and the cross-shaped frame 71 is in sliding contact with the bottom surfaces of the four locking strips 77 when moving; the cross-shaped frame 71 can abut against the four locking strips 77 and drive the four locking strips 77 to move upward after moving upward, the friction between the locking strips 77 and the extension sections of the elastic expansion rods 67 is large, and the locking strips 77 can lock the extension sections of the plurality of elastic expansion rods 67 in contact with them by cooperating with the support strips 76 after moving upward (as shown inFigure 11 As shown), this temporarily prevents the telescopic sections of multiple elastic telescopic rods 67 from extending or retracting.

[0041] In addition, please see Figure 6 , Figure 9 - Figure 11 The locking part 7 also includes four pads 78 and four washers 79. The four pads 78 are fixedly connected to the four mounting boxes 66, and the four washers 79 are fixedly connected to the four pads 78. When the grid frame 71 moves, it slides in contact with the bottom surfaces of the four pads 78. When the grid frame 71 moves upward, it abuts against the four pads 78 and drives the pads 78 to move upward. There is a large friction between the washers 79 and the rotating shafts 68. After the washers 79 abut against multiple rotating shafts 68, the rotating shafts 68 cannot rotate temporarily, achieving the effect of locking the rotating shafts 68 (e.g., Figure 11 As shown), the friction between the pad 78 and locking strip 77 and the grid frame 71 is small and does not affect the movement of the mounting box 66. When the telescopic sections of multiple elastic telescopic rods 67 are locked and multiple rotating shafts 68 are locked, the four sets of clamping plates 69 are in a rigid clamping state. Conversely, when the grid frame 71 does not move upward, the elastic telescopic rods 67 are equipped with springs. While the clamping plates 69 apply pressure to the rectangular circuit board, the clamping plates 69 drive the telescopic sections of the elastic telescopic rods 67 to retract through the rotating shafts 68 (as shown). Figure 6 As shown, when positioning an irregularly shaped circuit board, the clamping piece 69 can rotate via the rotating shaft 68. The clamping piece 69 can rotate along the edge of the irregularly shaped circuit board, maintaining the fit between the clamping piece 69 and the edge of the irregularly shaped circuit board. At this time, the four sets of clamping pieces 69 are in an elastic clamping state. Through the setting of the locking part 7, the operator can switch between the elastic clamping and rigid clamping states by rotating the bevel gear 75. The rigid clamping can improve the positioning accuracy of the centering positioning clamping, while the elastic clamping can allow the clamping pieces 69 on the four mounting boxes 66 to adapt to the shape of the irregularly shaped circuit board and then switch to rigid clamping, so that the clamping pieces 69 on the four mounting boxes 66 can maintain a high fit with the shape of the irregularly shaped circuit board, thereby positioning the irregularly shaped circuit board.

[0042] It is worth noting that, please refer to Figure 4 , Figure 8 Multiple vibrating plates 91 are fixedly connected to the outer wall of the support platform 9, and multiple levers 92 are fixedly connected to the outer wall of the turntable 61. When the vibrating plates 91 move, they contact the multiple levers 92 in sequence. When the turntable 61 rotates, it drives the multiple levers 92 to rotate. During the rotation of the multiple levers 92, they sequentially move the four vibrating plates 91. The vibrating plates 91 have a certain elasticity. After being moved by the levers 92, the vibrating plates 91 vibrate. The four vibrating plates 91 transmit the vibration to the support platform 9. The support platform 9 drives the irregularly shaped circuit board or rectangular circuit board above it to vibrate slightly. The irregularly shaped circuit board can be promoted to fit into the four sets of clamps 69 through slight vibration, thereby optimizing the positioning effect of the irregularly shaped circuit board.

[0043] It is worth mentioning that, please refer to Figure 2 , Figure 12 - Figure 14 The protection assembly 8 is used for preventing the circuit board in clamping from falling off when moving; the protection assembly 8 comprises two protection covers 81, two connecting seats 83, two sliding shafts 84 and two groove cylinders 85, the two protection covers 81 are both slidingly installed on the annular frame 5, the two protection covers 81 are centrally symmetrically arranged, the two groove cylinders 85 are respectively fixedly connected on the two mounting frames 2, the groove cylinder 85 is provided with an arc-shaped groove, the arc-shaped groove is composed of two obliquely arranged semicircular grooves (as shown in Figure 13 ), the two sliding shafts 84 are respectively slidingly connected in the arc-shaped grooves of the two groove cylinders 85, the two connecting seats 83 are respectively fixedly connected on the two sliding shafts 84, the two connecting seats 83 are respectively hingedly provided with two connecting rods 82, the four connecting rods 82 are respectively hingedly connected with two ends of the two protection covers 81 away from the connecting seats 83, when the annular frame 5 rotates, the two protection covers 81 revolve around the mounting shaft 4 as the axis, the two protection covers 81 revolve to drive the two connecting seats 83 to revolve synchronously through the four connecting rods 82, the sliding shaft 84 on the connecting seat 83 slides in the arc-shaped groove of the groove cylinder 85 at the same time of revolving, in the process of the annular frame 5 rotating one hundred and eighty degrees, the sliding shaft 84 slides in one of the semicircular grooves of the arc-shaped groove, in this process, the sliding shaft 84 slides along the semicircular groove away from the annular frame 5 first and then approaches the annular frame 5 (as shown in Figure 13 ), the sliding shaft 84 drives the connecting seat 83 to move synchronously when moving in the arc-shaped groove, the two connecting seats 83 can pull the two protection covers 81 to the direction of approaching the supporting table 9 through the four connecting rods 82 when the two connecting seats 83 move away from each other, after the two protection covers 81 approach the supporting table 9, the edge part of the clamped circuit board can be shielded, when the circuit board falls off in the rotating process, the circuit board can still be between the annular frame 5 and the two protection covers 81 due to the shielding of the two protection covers 81, the circuit board can be prevented from being thrown out of the annular frame 5 to be damaged, through the arrangement of the protection assembly 8, the two protection covers 81 can automatically approach the supporting table 9 when the annular frame 5 rotates, so as to block the flight track of the circuit board after falling off, and prevent the circuit board from falling to the ground to be damaged after falling off.

[0044] It is worth mentioning that, please refer to Figure 12 - Figure 14The protection assembly 8 further comprises two mounting rods 86, two baffles 87 and two shift shafts 88, the two mounting rods 86 are fixedly installed on the annular frame 5, the two baffles 87 are rotatably installed on the two mounting rods 86 respectively, and the two shift shafts 88 are fixedly connected to the two baffles 87 respectively. The protection cover 81 is provided with a sliding groove, the two shift shafts 88 are slidably connected to the sliding grooves of the two protection covers 81 respectively, the two baffles 87 are centrally symmetrically arranged, when the protection cover 81 moves towards the support table 9, the shift shaft 88 is driven to move towards the support table 9 through the sliding groove, the baffle 87 is swung towards the support table 9 by the shift shaft 88, the swinging distance of the end portion of the baffle 87 is greater than that of the shift shaft 88, so that the end portion of the baffle 87 can extend beyond the edge of the protection cover 81 (as shown in Figure 14 When the two protection covers 81 move to the closest position of the support table 9, the end portions of the two baffles 87 can shield most of the area of the circuit board, thereby increasing the protection range, avoiding the circuit board from being collided by external force when rotating, and preventing falling. Through the arrangement of the two baffles 87, the two baffles 87 can automatically extend when the two protection covers 81 are close to the support table 9, thereby increasing the protection area.

[0045] With the above structure, the working principle of the case is that the circuit board includes a rectangular circuit board and a special-shaped circuit board. When positioning the rectangular circuit board, the rectangular circuit board is placed on the support table 9, the top surface area of the support table 9 is smaller than the area of the smallest circuit board in the positioning range, so that the edge of the circuit board protrudes from the edge of the support table 9. The air cylinder 64 is started, the output end of the air cylinder 64 is retracted, the output end of the air cylinder 64 drives the sliding block 63 connected thereto to move towards the rotating disc 61 through the connecting block 65. The sliding block 63 drives the rotating disc 61 to rotate through the angle rod 62. When the rotating disc 61 rotates, the other three sliding blocks 63 are driven to move towards the rotating disc 61 synchronously through the other three angle rods 62. The rotating disc 61 is located below the support table 9. When the sliding block 63 moves, the mounting box 66 moves synchronously. Therefore, after the air cylinder 64 is started, the four mounting boxes 66 can move towards the support table 9 synchronously. When the mounting box 66 moves, the plurality of elastic expansion rods 67 move synchronously. The elastic expansion rods 67 drive the shaft 68 and the clamping pieces 69 above the shaft 68 to move synchronously. The plurality of clamping pieces 69 on each mounting box 66 are divided into a group. When the four mounting boxes 66 move towards the support table 9, the four groups of clamping pieces 69 are in contact with the four edges of the rectangular circuit board respectively. Since the four groups of clamping pieces 69 move synchronously and the pressure applied by the four groups of clamping pieces 69 to the four edges of the rectangular circuit board is relatively uniform, the four groups of clamping pieces 69 can apply uniform pressure to the four edges of the rectangular circuit board simultaneously during synchronous movement. When the rectangular circuit board deviates from the center of the support table 9, the four groups of clamping pieces 69 can move the rectangular circuit board to the center of the support table 9 and straighten the skewed rectangular circuit board. The output end of the air cylinder 64 is provided with a pressure sensor. When the pressure value acting on the output end of the air cylinder 64 reaches a set value, that is, after the four groups of clamping pieces 69 apply a certain pressure to the four edges of the rectangular circuit board, the air cylinder 64 stops retraction and enters the pressure maintaining state. At this time, the rectangular circuit board is clamped stably and centered and positioned on the support table 9 by the four groups of clamping pieces 69. The test device can be arranged on the operation table 1 and aligned with the support table 9 in advance. After the rectangular circuit board is centered and positioned, the test device can directly test the rectangular circuit board. After the servo motor 3 is started, the servo motor 3 drives the annular frame 5 and the other mounting shaft 4 to rotate one hundred and eighty degrees through the mounting shaft 4 connected thereto, so that the four groups of clamping pieces 69 above the annular frame 5 clamp the rectangular circuit board and drive the rectangular circuit board to rotate one hundred and eighty degrees. The jig can be used to position the dust collector shell on the operation table 1. Similarly, after the jig is aligned with the support table 9 and the annular frame 5 is rotated one hundred and eighty degrees, the jig can be driven to move upwards by the external driving device, so as to achieve the effect of placing the rectangular circuit board into the dust collector shell, so that the rectangular circuit board is assembled in place. Then the air cylinder 64 is closed.The output end of the air cylinder 64 extends to reset, as described above, the four mounting boxes 66 and the four sets of clamping pieces 69 are also reset, the four sets of clamping pieces 69 loosen the clamping of the rectangular circuit board, then the jig and the dust collector shell are reset by the external driving device, and the ring-shaped frame 5 is reset by the servo motor 3 and the mounting shaft 4, the clamping pieces 69 can be detached from the rotating shaft 68, and the workers can detach part of the clamping pieces 69 according to the actual use requirement, so as to avoid the movement interference between part of the clamping pieces 69 and the mounting slots on the dust collector shell during the assembly of the rectangular circuit board; the workers can rotate the first screw rod 611 with a screwdriver, and the first screw rod 611 can drive the mounting box 66 to slide on the sliding block 63 by the threaded connection principle through the first nut block 610 when the first screw rod 611 rotates, so as to adjust the position of the mounting box 66 on the sliding block 63, so that the workers can adjust the positions of the four mounting boxes 66 in advance according to the length and width of the rectangular circuit board to be positioned, so that the four sets of clamping pieces 69 are more suitable for the edges of the rectangular circuit board; through the setting of the positioning and clamping assembly 6, the four mounting boxes 66 can be synchronously moved to center, so that the clamping pieces 69 on the four mounting boxes 66 can be centered and positioned and clamped on the rectangular circuit board, so as to achieve the effect of automatic positioning, the positioning accuracy is high, and cooperating with the rotation of the ring-shaped frame 5, the workers can detect and assemble the rectangular circuit board, the operable procedures on the operation table 1 are increased, and the overall work efficiency is improved.

[0046] When the bevel gear rod 75 rotates, the bevel gear rod 75 drives the second screw rod 73 to rotate through the bevel gear ring 74, and the second screw rod 73 can drive the well-shaped frame 71 to move up or down through the second nut block 72 by using the screw connection principle when the second screw rod 73 rotates. After the well-shaped frame 71 moves up, it can abut against the four locking strips 77 and drive the four locking strips 77 to move up. Taking one of the locking strips 77 as an example, the friction between the supporting strip 76 and the extension segment of the elastic extension rod 67 is small, and the supporting strip 76 mainly plays a supporting role. The friction between the locking strip 77 and the extension segment of the elastic extension rod 67 is large. After the locking strip 77 moves up, it is locked with the extension segment of the elastic extension rod 67 through cooperation with the supporting strip 76, so that the extension segment of the elastic extension rod 67 cannot temporarily stretch and contract. The well-shaped frame 71 also abuts against and drives the four pads 78 to move up. Taking one of the pads 78 as an example, after the pad 78 moves up, the gasket 79 on the pad 78 abuts against the bottom of the multiple shafts 68 above it, and the friction between the gasket 79 and the shaft 68 is large. After the gasket 79 abuts against the multiple shafts 68, the shaft 68 cannot rotate temporarily, achieving the effect of locking the shaft 68. The friction between the pad 78 and the locking strip 77 and the well-shaped frame 71 is small, and does not affect the movement of the mounting box 66. When the extension segment of the multiple elastic extension rods 67 is locked and the multiple shafts 68 are locked, the four groups of clamping pieces 69 are in a rigid clamping state. When positioning the rectangular circuit board, the four groups of clamping pieces 69 are in a rigid clamping state, thereby ensuring the positioning accuracy.Conversely, when the well-shaped frame 71 is not moved up, the elastic telescopic rod 67 is provided with a spring, and when the clamping pieces 69 press the rectangular circuit board, the clamping pieces 69 drive the telescopic section of the elastic telescopic rod 67 to contract through the rotating shaft 68. When the special-shaped circuit board is positioned, the clamping pieces 69 can be rotated through the rotating shaft 68, and the clamping pieces 69 can be rotated along the edge of the special-shaped circuit board to maintain the fit of the clamping pieces 69 with the edge of the special-shaped circuit board. At this time, the four sets of clamping pieces 69 are in an elastic clamping state. Before positioning the special-shaped circuit board, the four sets of clamping pieces 69 need to be calibrated. First, switch to the elastic clamping state, then place the special-shaped circuit board on the support table 9, and calibrate the accurate position of the first special-shaped circuit board to be positioned by matching and calibrating with the detection device. This operation can also be performed using a sample plate, and then temporarily fixed by using an external clamping device. After the special-shaped circuit board is positioned and fixed, the air cylinder 64 is started, and after the four clamping pieces 69 approach the special-shaped circuit board, the four clamping pieces 69 are turned and contracted according to the contact surface of the clamping pieces 69 with the special-shaped circuit board through the cooperation of the rotating shaft 68 and the elastic telescopic rod 67. When the air cylinder 64 is pressure-kept, the four clamping pieces 69 form a shape that fits the edge of the special-shaped circuit board. At this time, the tapered gear rod 75 is rotated to switch to the rigid clamping state, and then the air cylinder 64 is closed. After the four clamping pieces 69 are relaxed, the multiple elastic telescopic rods 67 are locked, and the multiple rotating shafts 68 are locked, so that the four sets of clamping pieces 69 can continuously maintain the current state. In the subsequent positioning process, when the four sets of clamping pieces 69 clamp the special-shaped circuit board, the special-shaped circuit board can move along the contact surface formed by the four sets of clamping pieces 69, and finally the special-shaped circuit board is embedded in the four sets of clamping pieces 69. At this time, the special-shaped circuit board is accurately positioned and consistent with the position of the special-shaped circuit board calibrated before. While the four mounting boxes 66 move, the rotating disc 61 also rotates. The rotating disc 61 drives the multiple tabs 92 to rotate, and the multiple tabs 92 in turn drive the four reed plates 91 to vibrate. The reed plates 91 have a certain elasticity, and the reed plates 91 vibrate after being driven by the tabs 92. The four reed plates 91 transmit the vibration to the support table 9, and the support table 9 drives the special-shaped circuit board or the rectangular circuit board above to vibrate slightly. The special-shaped circuit board can be embedded in the four sets of clamping pieces 69 through slight vibration, thereby optimizing the positioning effect of the special-shaped circuit board. Through the setting of the locking part 7, the operator can switch between elastic clamping and rigid clamping by rotating the tapered gear rod 75. Rigid clamping can improve the positioning accuracy of the center positioning and clamping, while elastic clamping can make the clamping pieces 69 on the four mounting boxes 66 adapt to the shape of the special-shaped circuit board, and then convert to rigid clamping to make the clamping pieces 69 on the four mounting boxes 66 maintain high fit with the shape of the special-shaped circuit board, thereby positioning the special-shaped circuit board.

[0047] When the ring-shaped frame 5 rotates, the two protective covers 81 are synchronously rotated by the ring-shaped frame 5, and the two protective covers 81 revolve around the mounting shaft 4. When the two protective covers 81 revolve, the two connecting seats 83 are synchronously revolved by the four connecting rods 82. The slide shafts 84 on the connecting seats 83 slide in the arc-shaped slots of the groove cylinder 85 while revolving. The arc-shaped slots are composed of two semicircular slots arranged obliquely. During the rotation of the ring-shaped frame 5 by 180 degrees, the slide shafts 84 slide in one of the semicircular slots of the arc-shaped slots. During this process, the slide shafts 84 slide away from the ring-shaped frame 5 first and then slide towards the ring-shaped frame 5 along the semicircular slot. When the slide shafts 84 move in the arc-shaped slots, the connecting seats 83 are synchronously moved, so that the two connecting seats 83 can move away from each other first and then move towards each other during the revolution by 180 degrees. When the two connecting seats 83 move away from each other, the two protective covers 81 can be pulled towards the support table 9 by the four connecting rods 82. After the two protective covers 81 move towards the support table 9, the edge portions of the clamped circuit board can be shielded. When the circuit board falls off during the rotation, the circuit board can still be between the ring-shaped frame 5 and the two protective covers 81 due to the shielding of the two protective covers 81, so that the circuit board can be prevented from flying out of the ring-shaped frame 5 and being damaged. After the ring-shaped frame 5 rotates to the position, the two protective covers 81 are reset to the initial positions and do not shield the circuit board. When the protective covers 81 move towards the support table 9, the protective covers 81 drive the drive shafts 88 to move towards the support table 9 through the sliding grooves. The drive shafts 88 drive the baffles 87 to swing on the mounting rods 86 towards the support table 9. Before the protective covers 81 move, the baffles 87 are below the protective covers 81. Since the swinging distance of the end portions of the baffles 87 is greater than that of the drive shafts 88, the end portions of the baffles 87 can extend out of the edges of the protective covers 81. When the two protective covers 81 move closest to the support table 9, the end portions of the two baffles 87 can shield most of the area of the circuit board, so that the shielding range is increased. The circuit board can be prevented from being collided by external force during the rotation while being prevented from falling off. After the two protective covers 81 are reset, the two baffles 87 are also reset below the two protective covers 81. The automatic extension and retraction mechanism of the baffles 87 can reduce the area of the protective covers 81, so that the operation is not affected by the large protective covers 81. Through the arrangement of the protective assembly 8, the two protective covers 81 can automatically move towards the support table 9 during the rotation of the ring-shaped frame 5, so that the flight track of the circuit board after falling off can be shielded and the circuit board can be prevented from falling to the ground and being damaged after falling off.
