Description

[0002] With the growing demand for intelligence, vacuum cleaners need to have multiple functions such as automatic navigation, intelligent obstacle avoidance, dust detection, and interaction with users, while achieving performance optimization and compact structure. Ordinary circuit boards are difficult to meet, so customized design of circuit boards is required. Customized circuit boards can be designed according to specific functional requirements, integrating various sensors, controllers and communication modules, etc., so that the vacuum cleaner can sense the surrounding environment and take corresponding actions. Customized circuit boards include testing and assembly processes in the production process. During testing, the circuit board needs to be positioned and then tested using 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, since the circuit board needs to be installed in a specified position, precise positioning is also required.

[0003] However, the existing technology has the following problems: In the existing technology, when positioning circuit boards, most of them still rely on manual positioning by operators. However, the accuracy of manual positioning is limited. Therefore, it often happens that after the operators manually adjust the position of the circuit board on the operating table, they find that the position of the circuit board is inaccurate during testing, and then they have to readjust the position, which delays the operation time and affects the overall operation efficiency.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention. Example

[0021] See also Figure 1 - Figure 6A customized circuit board positioning device for an intelligent vacuum cleaner includes an operating table 1, on which two mounting frames 2 are fixedly mounted, on which mounting shafts 4 are rotatably mounted, a ring frame 5 is fixedly connected between the two mounting shafts 4, and a support platform 9 is fixedly mounted at the center position of the top surface of the ring frame 5; it also includes a positioning clamping assembly 6 for clamping the circuit board in a central positioning manner; the positioning clamping assembly 6 includes four sliders 63, which are all slidably connected to the ring frame 5, and the four sliders 63 are respectively slidably connected to the mounting boxes 66, and a plurality of elastic telescopic rods 67 are installed inside the mounting boxes 66; a turntable 61 is rotatably mounted on the inner wall of the ring frame 5, and four angle rods 62 are hinged on the turntable 61, and the four angle rods 62 are away from the turntable 61. One end is hinged to four sliders 63 respectively, and a cylinder 64 is fixedly installed on the inner wall of the turntable 61. A pressure sensor is provided at the output end of the cylinder 64. When the pressure value received by the output end of the cylinder 64 reaches the set value, the cylinder 64 stops contracting and enters the pressure holding state. The output end of the cylinder 64 is fixedly connected to a connecting block 65, and the connecting block 65 is fixedly connected to one of the sliders 63. The output end of the cylinder 64 drives the slider 63 connected thereto to move in the direction close to the turntable 61 through the connecting block 65. The slider 63 drives the turntable 61 to rotate through the angle rod 62. When the turntable 61 rotates, the other three sliders 63 are driven synchronously to move in the direction close to the turntable 61 through the other three angle rods 62, so that the four sliders 63 can move synchronously in the center (such as Figure 4 As shown in the figure, when the slider 63 moves, the installation box 66 is driven to move synchronously; the circuit board is placed on the support platform 9, and the top surface area of ​​the support platform 9 is smaller than the area of ​​the smallest circuit board in the positioning range, so that the edge of the circuit board will protrude from the edge of the support platform 9, and the elastic telescopic rod 67 is provided with a telescopic section, and the telescopic section of the elastic telescopic rod 67 is slidably connected with the installation box 66, and a rotating shaft 68 is rotatably installed on the telescopic section of the elastic telescopic rod 67. The top of the rotating shaft 68 is connected with a clip 69, and the clip 69 can be removed from the rotating shaft 68. The multiple clips 69 on each installation box 66 are divided into a group. When the four installation boxes 66 are close to the support platform 9, the four groups of clips 69 are in contact with the four sides of the rectangular circuit board respectively, and a relatively uniform pressure is applied to the four sides of the rectangular circuit board at the same time (as shown in the figure). Figure 5 As shown in the figure), when the rectangular circuit board deviates from the center of the support platform 9, the four groups of clips 69 can move the rectangular circuit board to the center of the support platform 9 and straighten the skewed rectangular circuit board. The four groups of clips 69 achieve the effect of centering and clamping the circuit board. Through the setting of the positioning and clamping component 6, the four installation boxes 66 can be synchronously moved to the center, so that the clips 69 on the four installation boxes 66 can center and clamp the rectangular circuit board, thereby achieving the effect of automatic positioning with high positioning accuracy.

[0022] For further information, see Figure 3A servo motor 3 is fixedly mounted on one of the mounting frames 2, and the output end of the servo motor 3 is fixedly connected to one of the mounting shafts 4. After the servo motor 3 is started, the servo motor 3 drives the annular frame 5 and the other mounting shaft 4 to rotate 180 degrees through the mounting shaft 4 connected thereto, so that the four groups of clips 69 above the annular frame 5 clamp the rectangular circuit board and drive the rectangular circuit board to rotate 180 degrees. A jig can be set on the operating table 1 to position the vacuum cleaner housing, which is convenient for users to assemble circuit boards. By utilizing the rotation of the annular frame 5, the operator can perform inspection and assembly operations on the rectangular circuit board, which increases the operable processes on the operating table 1 and thus improves the overall work efficiency.

[0023] Further, see Figure 7 The inner wall of the slider 63 is rotatably installed with a first screw 611, and the bottom surface of the installation box 66 is fixedly connected with a first nut block 610. The first nut block 610 is threadedly connected to the first screw 611. The operator can use a screwdriver to rotate the first screw 611. When the first screw 611 rotates, the threaded connection principle can be used to drive the installation box 66 to slide on the slider 63 through the first nut block 610, thereby adjusting the position of the installation box 66 on the slider 63, so that the operator can adjust the position of the four installation boxes 66 in advance according to the length and width of the rectangular circuit board to be positioned, so that the four groups of clips 69 can better adapt to the edge of the rectangular circuit board.

[0024] Also, see Figure 2 、 Figure 9 - Figure 11 The positioning clamping assembly 6 also includes a locking portion 7 for switching between the two clamping states of elastic clamping and rigid clamping. The locking portion 7 includes a well frame 71, which is vertically slidably connected to the top surface of the annular frame 5. The center of the well frame 71 is fixedly connected to a second nut block 72. A second screw rod 73 is rotatably mounted on the annular frame 5. A locking strip 77 is slidably connected to the bottom of the mounting box 66; the locking portion 7 also includes a bevel gear ring 74, a bevel gear rod 75 and four support bars 76. The second screw 73 is threadedly connected to the second nut block 72. The bevel gear ring 74 is fixedly connected to the outer wall of the second screw 73. The bevel gear rod 75 is rotatably mounted on the annular frame 5, and the bevel gear rod 75 is engaged with the bevel gear ring 74. The four support bars 76 are respectively fixedly connected to the top inner walls of the four mounting boxes 66, and the support bars 76 are in sliding contact with the telescopic sections of the multiple elastic telescopic rods 67 in the mounting box 66. The friction between the support bars 76 and the telescopic sections of the elastic telescopic rods 67 is relatively small, and the support bars 76 mainly play a supporting role. The well frame 71 is in sliding contact with the bottom surfaces of the four locking bars 77 during movement; after the well frame 71 moves upward, it can resist the four locking bars 77 and drive the four locking bars 77 to move upward. The friction between the locking bars 77 and the telescopic sections of the elastic telescopic rods 67 is relatively large. After the locking bars 77 move upward, they will lock the telescopic sections of the multiple elastic telescopic rods 67 in contact with them through cooperation with the support bars 76 (such as Figure 11 As shown), the telescopic sections of the multiple elastic telescopic rods 67 are temporarily unable to be telescoped.

[0025] In addition, see Figure 6 、 Figure 9 - Figure 11 The locking portion 7 also includes four pads 78 and four gaskets 79. The four pads 78 are respectively fixedly connected to the four mounting boxes 66. The four gaskets 79 are respectively fixedly connected to the four gaskets 78. The well frame 71 slides in contact with the bottom surfaces of the four gaskets 78 when it moves. When the well frame 71 moves upward, it abuts against the four gaskets 78 and drives the gaskets 78 to move upward. There is a large friction force between the gaskets 79 and the rotating shaft 68. After the gaskets 79 abut against multiple rotating shafts 68, the rotating shaft 68 cannot rotate temporarily, thereby achieving the effect of locking the rotating shaft 68 (such as Figure 11 As shown in FIG, the friction between the pad 78 and the locking strip 77 and the well frame 71 is small and does not affect the movement of the installation box 66. When the telescopic sections of the multiple elastic telescopic rods 67 are locked and the multiple shafts 68 are locked, the four groups of clips 69 are in a rigid clamping state. On the contrary, when the well frame 71 does not move upward, the elastic telescopic rod 67 is provided with a spring. When the clip 69 applies pressure to the rectangular circuit board, the clip 69 drives the telescopic section of the elastic telescopic rod 67 to contract through the shaft 68 (as shown in FIG. Figure 6 As shown), when the special-shaped circuit board is positioned, the clip 69 can be rotated by the rotating shaft 68, and the clip 69 can be rotated along the edge of the special-shaped circuit board to maintain the fit between the clip 69 and the edge of the special-shaped circuit board. At this time, the four groups of clips 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 rod 75. The rigid clamping can improve the positioning accuracy of the centering clamping, and the elastic clamping can make the clips 69 on the four mounting boxes 66 adapt to the shape of the special-shaped circuit board, and then convert to rigid clamping, so that the clips 69 on the four mounting boxes 66 can maintain a high fit with the shape of the special-shaped circuit board, thereby positioning the special-shaped circuit board.

[0026] It is worth noting that see Figure 4 、 Figure 8 The outer wall of the support platform 9 is fixedly connected with multiple vibration plates 91, and the outer wall of the turntable 61 is fixedly connected with multiple paddles 92. When the vibration plate 91 moves, it contacts the multiple paddles 92 in turn. When the turntable 61 rotates, it drives the multiple paddles 92 to rotate. During the rotation process, the multiple paddles 92 sequentially poke four vibration plates 91. The vibration plate 91 has a certain elasticity. After being paddled by the paddle 92, the vibration is generated. The four vibration plates 91 transmit the vibration to the support platform 9, and the support platform 9 drives the special-shaped circuit board or rectangular circuit board above it to vibrate slightly. The special-shaped circuit board can be facilitated to be embedded in the four groups of clips 69 through slight vibration, thereby optimizing the positioning effect of the special-shaped circuit board.

[0027] It is worth noting that, please refer to Figure 2 、 Figure 12 - Figure 14 , the protective assembly 8 is used to prevent the clamped circuit board from falling during movement; the protective assembly 8 includes two protective covers 81, two connecting seats 83, two sliding shafts 84 and two groove cylinders 85. The two protective covers 81 are slidably mounted on the annular frame 5. The two protective covers 81 are centrally symmetrically arranged. The two groove cylinders 85 are respectively fixedly connected to the two mounting frames 2. The groove cylinder 85 is provided with an arc groove, which is composed of two obliquely arranged semicircular grooves (such as Figure 13 As shown), the two sliding shafts 84 are respectively slidably connected in the arc grooves of the two grooved cylinders 85, and the two connecting seats 83 are respectively fixedly connected to the two sliding shafts 84. The two connecting seats 83 are respectively hinged with two connecting rods 82, and the ends of the four connecting rods 82 away from the connecting seats 83 are respectively hinged to the two ends of the two protective covers 81. When the annular frame 5 rotates, the two protective covers 81 revolve around the mounting shaft 4 as the axis. When the two protective covers 81 revolve, the two connecting seats 83 are driven to revolve synchronously through the four connecting rods 82. The sliding shaft 84 on the connecting seat 83 slides in the arc groove of the grooved cylinder 85 while revolving. During 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 groove. During this process, the sliding shaft 84 first moves away from the annular frame 5 along the semicircular groove and then approaches the annular frame 5 (as shown in FIG. Figure 13 As shown in the figure, the sliding shaft 84 drives the connecting seat 83 to move synchronously when moving in the arc groove. When the two connecting seats 83 move away from each other, the two protective covers 81 can be pulled toward the support platform 9 through the four connecting rods 82. After the two protective covers 81 approach the support platform 9, they can block the edge of the clamped circuit board. When the circuit board falls off during the rotation, due to the blocking of the two protective covers 81, the circuit board can still be placed between the annular frame 5 and the two protective covers 81, which can prevent the circuit board from being thrown out of the annular frame 5 and causing the circuit board to be damaged. Through the setting of the protective component 8, the two protective covers 81 can automatically approach the support platform 9 when the annular frame 5 rotates, so as to block the flight trajectory of the circuit board after it falls off, and prevent the circuit board from falling to the ground and being damaged after falling off.

[0028] It is worth mentioning that see Figure 12 - Figure 14The protective assembly 8 also includes two mounting rods 86, two baffles 87 and two dial shafts 88. The two mounting rods 86 are fixedly mounted on the annular frame 5, and the two baffles 87 are rotatably mounted on the two mounting rods 86. The two dial shafts 88 are fixedly connected to the two baffles 87. A slide groove is provided on the protective cover 81. The two dial shafts 88 are slidably connected to the slide grooves of the two protective covers 81 respectively. The two baffles 87 are centrally symmetrically arranged. When the protective cover 81 moves toward the direction close to the support platform 9, the slide groove drives the dial shaft 88 to move toward the direction close to the support platform 9. The dial shaft 88 drives the baffle 87 to swing toward the direction close to the support platform 9. The swinging distance of the end of the baffle 87 is greater than the dial shaft 88, so that the end of the baffle 87 can extend out of the edge of the protective cover 81 (such as Figure 14 As shown in the figure), when the two protective covers 81 move to the closest position to the support platform 9, the ends of the two baffles 87 can block most of the area of ​​the circuit board, thereby increasing the protection range. While preventing it from falling, it can also prevent the circuit board from being hit by external forces during rotation. Through the setting of the two baffles 87, the two baffles 87 can automatically extend when the two protective covers 81 are close to the support platform 9, thereby increasing the protection area.

[0029] With the above structure, the working principle of this 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 9. The top surface area of ​​the support 9 is smaller than the area of ​​the smallest circuit board in the positioning range, so that the edge of the circuit board will protrude from the edge of the support 9. The cylinder 64 is started, and the output end of the cylinder 64 contracts. The output end of the cylinder 64 drives the slider 63 connected to it to move toward the direction close to the turntable 61 through the connecting block 65. The slider 63 drives the turntable 61 to rotate through the angle rod 62. When the turntable 61 rotates, the other three sliders 63 are driven to move synchronously toward the direction close to the turntable 61 through the other three angle rods 62. The turntable 6 1 is located below the support platform 9. When the slider 63 moves, it drives the installation box 66 to move synchronously. Therefore, after the cylinder 64 is started, the four installation boxes 66 can be synchronously close to the support platform 9. When the installation box 66 moves, it drives multiple elastic telescopic rods 67 to move synchronously. The elastic telescopic rods 67 drive the rotating shaft 68 and the clips 69 above it to move synchronously. The multiple clips 69 on each installation box 66 are divided into a group. When the four installation boxes 66 are close to the support platform 9, the four groups of clips 69 are in contact with the four sides of the rectangular circuit board respectively. Since the four groups of clips 69 move synchronously and the pressure applied by the four groups of clips 69 to the four sides of the rectangular circuit board is relatively uniform, the four groups of clips 69 can be moved synchronously. It can apply relatively uniform pressure to the four sides of the rectangular circuit board at the same time. When the rectangular circuit board deviates from the center of the pallet 9, the four groups of clamps 69 can move the rectangular circuit board to the center of the pallet 9 and straighten the skewed rectangular circuit board. The output end of the cylinder 64 is provided with a pressure sensor. When the pressure value received by the output end of the cylinder 64 reaches the set value, that is, the four groups of clamps 69 apply a certain pressure to the four sides of the rectangular circuit board, the cylinder 64 stops contracting and enters a pressure holding state. At this time, the rectangular circuit board is clamped stably and is centered on the pallet 9 by the four groups of clamps 69. A test device can be set on the operating table 1, and the test device is aligned with the pallet 9 in advance. When the rectangular circuit board After being centered, the test device can directly test the rectangular circuit board. After starting the servo motor 3, the servo motor 3 drives the annular frame 5 and another mounting shaft 4 to rotate 180 degrees through the mounting shaft 4 connected thereto, so that the four sets of clips 69 above the annular frame 5 clamp the rectangular circuit board and drive the rectangular circuit board to rotate 180 degrees. A jig can be set on the operating table 1 to position the vacuum cleaner housing. Similarly, after aligning the jig with the support table 9 and rotating the annular frame 5 180 degrees, the external drive device can be used to drive the jig upward, thereby achieving the effect of placing the rectangular circuit board into the vacuum cleaner housing. The rectangular circuit board is assembled in place, and then the cylinder 64 is closed.The output end of the cylinder 64 extends and resets. Based on the above principle, the four mounting boxes 66 and the four groups of clips 69 are also reset. The four groups of clips 69 loosen their grip on the rectangular circuit board, and then the jig and the vacuum cleaner shell are reset by the external drive device. The annular frame 5 is then reset by the servo motor 3 and the mounting shaft 4. The clips 69 can be removed from the rotating shaft 68. The operator can remove part of the clips 69 according to actual use needs to avoid movement interference between part of the clips 69 and the mounting slots on the vacuum cleaner shell when assembling the rectangular circuit board. The operator can use a screwdriver to rotate the first screw 611. When the first screw 611 rotates, the threaded connection principle can be used to drive the mounting box through the first nut block 610. 66 slides on the slider 63, thereby adjusting the position of the installation box 66 on the slider 63, allowing the operator to adjust the position of the four installation boxes 66 in advance according to the length and width of the rectangular circuit board to be positioned, so that the four sets of clips 69 can better adapt to the edge of the rectangular circuit board; through the setting of the positioning clamping assembly 6, the four installation boxes 66 can be synchronously moved to the center, so that the clips 69 on the four installation boxes 66 can center the rectangular circuit board, thereby achieving the effect of automated positioning with high positioning accuracy. In conjunction with the rotation of the ring frame 5, the operator can perform inspection and assembly operations on the rectangular circuit board, increasing the number of operational processes on the operating table 1, thereby improving overall work efficiency.

[0030] When the second screw rod 73 is rotated, the second screw rod 73 can be driven by the second nut block 72 to drive the cross frame 71 to move up or down by the second nut block 72 using the threaded connection principle. After the cross frame 71 moves up, it can resist the four locking bars 77 and drive the four locking bars 77 to move up. Taking one of the locking bars 77 as an example, the friction between the support bar 76 and the telescopic section of the elastic telescopic rod 67 is relatively small. The support bar 76 mainly plays a supporting role, and the friction between the locking bar 77 and the telescopic section of the elastic telescopic rod 67 is relatively large. After the locking bar 77 moves up, it will lock the telescopic sections of the multiple elastic telescopic rods 67 in contact with it through the cooperation with the support bar 76, so that the telescopic sections of the multiple elastic telescopic rods 67 cannot be retracted temporarily. When the bracket 71 moves upward, it will also press against the four pads 78 and drive the pads 78 upward. Taking one of the pads 78 as an example, after the pads 78 move upward, the pads 79 on the pads 78 press against the bottoms of the multiple shafts 68 above it. There is a large friction between the pads 79 and the shafts 68. After the pads 79 press against the multiple shafts 68, the shafts 68 cannot rotate temporarily, achieving the effect of locking the shafts 68. The friction between the pads 78 and the locking strips 77 and the cross-shaped bracket 71 is small and does not affect the movement of the installation box 66. When the telescopic sections of the multiple elastic telescopic rods 67 are locked and the multiple shafts 68 are locked, the four groups of clips 69 are in a rigid clamping state. When positioning the rectangular circuit board, the four groups of clips 69 adopt a rigid clamping state, thereby ensuring positioning accuracy.On the contrary, when the cross frame 71 does not move up, the elastic telescopic rod 67 is provided with a spring. When the clip 69 applies pressure to the rectangular circuit board, the clip 69 drives 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 clip 69 can be rotated through the rotating shaft 68. The clip 69 can rotate along the edge of the special-shaped circuit board to maintain the fit between the clip 69 and the edge of the special-shaped circuit board. At this time, the four groups of clips 69 are in an elastic clamping state. Before positioning the special-shaped circuit board, the four groups of clips 69 need to be calibrated. First, switch to the elastic clamping state, and then place the special-shaped circuit board on the support table 9. By matching and calibrating with the detection device, first calibrate Accurately locate the exact position of the first special-shaped circuit board to be positioned. This operation can also be performed using a template, and then temporarily fixed with an external clamping device. After the special-shaped circuit board is positioned and fixed, start the cylinder 64. After the four groups of clips 69 approach the special-shaped circuit board, the four groups of clips 69 cooperate with the rotating shaft 68 and the elastic telescopic rod 67 to turn and shrink according to the contact surface between the clip 69 itself and the special-shaped circuit board. When the cylinder 64 maintains pressure, the four groups of clips 69 form a shape that fits the edge of the special-shaped circuit board. At this time, rotate the bevel gear rod 75 to switch to a rigid clamping state, and then close the cylinder 64. After the four groups of clips 69 release their clamping, since multiple elastic telescopic rods 67 are locked, multiple rotating shafts 68 The four sets of clamps 69 are locked so that they can maintain their current state. In the subsequent positioning process, the four sets of clamps 69 can make the special-shaped circuit board move along the contact surface formed by the four sets of clamps 69 when clamping the special-shaped circuit board, and finally make the special-shaped circuit board fit into the four sets of clamps 69. At this time, the special-shaped circuit board is accurately positioned, which is consistent with the position of the special-shaped circuit board calibrated before. When the four mounting boxes 66 move, the turntable 61 also rotates. When the turntable 61 rotates, it drives the multiple paddles 92 to rotate. During the rotation of the multiple paddles 92, the four vibrating plates 91 are sequentially dialed. The vibrating plates 91 have a certain elasticity. After being dialed by the paddles 92, the vibrating plates 91 vibrate, and the four vibrating plates 91 transmit the vibration. The bracket 9 is handed over to the support platform 9, which causes the special-shaped circuit board or rectangular circuit board above it to vibrate slightly. The slight vibration can help the special-shaped circuit board fit into the four sets of clips 69, thereby optimizing the positioning effect of the special-shaped circuit board. The setting of the locking part 7 allows the operator to switch between the elastic clamping and rigid clamping states by rotating the bevel gear rod 75. The rigid clamping can improve the positioning accuracy of the centering clamping, while the elastic clamping can make the clips 69 on the four mounting boxes 66 adapt to the shape of the special-shaped circuit board, and then switch to rigid clamping, so that the clips 69 on the four mounting boxes 66 can maintain a high degree of fit with the shape of the special-shaped circuit board, thereby positioning the special-shaped circuit board.

[0031] When the annular frame 5 rotates, the annular frame 5 drives the two protective covers 81 to rotate synchronously. The two protective covers 81 revolve around the mounting shaft 4. When the two protective covers 81 revolve, the two connecting seats 83 are driven to revolve synchronously through the four connecting rods 82. The sliding shaft 84 on the connecting seat 83 slides in the arc groove of the groove cylinder 85 while revolving. The arc groove is composed of two obliquely arranged semicircular grooves. When the annular frame 5 rotates 180 degrees, the sliding shaft 84 slides in one of the semicircular grooves of the arc groove. In this process, the sliding shaft 84 first moves away from the annular frame 5 along the semicircular groove and then approaches the annular frame 5. When the sliding shaft 84 moves in the arc groove, it drives the connecting seat 83 to move synchronously. When the two connecting seats 83 move away from each other, they can first move closer to each other and then move closer to each other through the four connecting rods 82. When the two connecting seats 83 move away from each other, the two protective covers 81 can be pulled toward the support platform 9. After the two protective covers 81 are close to the support platform 9, they can shield the edge of the clamped circuit board. When the circuit board falls off during the rotation, the circuit board can still be between the annular frame 5 and the two protective covers 81 due to the shielding of the two protective covers 81, which can prevent the circuit board from being thrown out of the annular frame 5 and causing the circuit board to be damaged. After the annular frame 5 is rotated into place, the two protective covers 81 are reset to the initial position without any damage to the circuit board. The protective cover 81 is blocked. When the protective cover 81 moves toward the direction close to the platform 9, the protective cover 81 drives the dial shaft 88 to move toward the direction close to the platform 9 through the slide groove. The dial shaft 88 drives the baffle 87 to swing on the mounting rod 86 toward the direction close to the platform 9. Before the protective cover 81 is moved, the baffle 87 is located below the protective cover 81. Since the swing distance of the end of the baffle 87 is greater than the dial shaft 88, the end of the baffle 87 can extend out of the edge of the protective cover 81. When the two protective covers 81 move to the closest to the platform 9, the ends of the two baffles 87 can cover most of the area of ​​the circuit board, thereby increasing the protection range and preventing the circuit board from falling while also preventing it from falling. When it is hit by external force during rotation, after the two protective covers 81 are reset, the two baffles 87 are also reset to the bottom of the two protective covers 81 again. The automatic telescopic mechanism of the baffle 87 can reduce the area of ​​the protective cover 81 itself, thereby avoiding the impact of the protective cover 81 being too large on the operation; through the setting of the protective component 8, the two protective covers 81 can automatically approach the support platform 9 when the ring frame 5 rotates, so as to block the flight trajectory of the circuit board after it falls off, and avoid the circuit board from falling to the ground and being damaged after falling off; through the setting of the two baffles 87, the two baffles 87 can automatically extend when the two protective covers 81 are close to the support platform 9, thereby increasing the protection area.
