[0012] Further, a pressing round block is fixedly connected to the front end of the extrusion round rod.

[0013] Further, a dust-proof cover is engaged and connected to the upper surface of the positioning plate.

[0014] Beneficial effects: Through the ingenious structural design, the device realizes the precise adjustment and stable fixation of the angle of the positioning plate. The cooperation of the turntable, the rotating rod, the wedge-shaped block, the transmission tooth and the lower gear of the rotating column enables the user to easily adjust the angle of the positioning plate according to actual needs. The existence of the locking column ensures that after the angle is adjusted, the device can be firmly locked and will not change the angle due to external interference. This function is extremely important in practical applications. Whether it is in the assembly of precision instruments, the positioning in industrial production, or the operation in the laboratory, it can ensure the accuracy and stability of the work. For example, on the assembly line of electronic products, precise angle adjustment can make the installation of parts more accurate and improve product quality; while stable fixation can ensure that there is no accidental movement during the operation and guarantee production safety;

[0015] The cooperation of the clamping block, the card slot, the slider and the card plate cavity realizes quick connection and fixation, providing convenience for various operations. At the same time, the sliding of the slider in the chute and the related air-squeezing and air-releasing structures make the clamping operation flexible and controllable. In addition, the pressing round block at the front end of the extrusion round rod increases the operation area, making the operation of locking and unlocking the angle of the rotating column more convenient. This design greatly improves work efficiency, reduces operation time and labor costs. In some work scenarios that require frequent workpiece replacement or adjustment, the convenient operation advantage of this device is particularly obvious, and it can quickly adapt to different work requirements and improve production efficiency;

[0016] In the initial state, spring five is in a natural stretched state, pushing the air-squeezing plate against the right side of the spring groove. At the same time, spring six is also in a natural stretched state. The wedge-shaped slider is at the upper position near the locking chute, and the positioning post is engaged with the positioning groove on the base, ensuring the stability of the device when the circuit board is not placed. When the circuit board is placed in the card slot, its right edge contacts the extrusion plate, pushing the extrusion plate, the cross plate, and the air-squeezing plate to move to the right, compressing spring five and squeezing the air in the spring groove into the extrusion groove. During this process, the air entering the extrusion groove pushes the cross wedge plate to slide to the right. Since the cross wedge plate contacts the inclined surface of the wedge-shaped slider, it further squeezes the wedge-shaped slider to slide upward against the elastic force of spring six, driving the cylinder and the positioning post to move upward, realizing the disengagement and engagement of the positioning post and the positioning groove. Only after the circuit board is clamped and fixed can the positioning plate rotate, effectively preventing the risk of the circuit board falling due to rotation caused by loose clamping, greatly improving the safety and reliability of the processing process.

Detailed implementation mode

[0027] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments. Embodiment 1

[0028] As Figures 1-7As shown in the figure, a positioning seat for circuit board processing is provided, including a base 1. A rotating opening 2 is formed on the upper surface of the base 1. A rotating groove 3 is formed inside the rotating opening 2. A rotating column 4 is rotatably connected inside the rotating opening 2. A limiting ring 5 is fixedly connected to the outer side wall of the rotating column 4. The limiting ring 5 is slidably connected with the rotating groove 3. A positioning plate 6 is fixedly connected to the upper surface of the rotating column 4. A clamping block 7 is fixedly connected to the right side of the upper surface of the positioning plate 6. A clamping groove 8 is formed on the left side of the clamping block 7. A sliding groove 9 is formed on the left side of the upper surface of the positioning plate 6. A slider 10 is slidably connected inside the sliding groove 9. A clamping plate cavity 11 is fixedly connected to the right side of the slider 10. An air squeezing groove 12 is fixedly connected to the right side inside the sliding groove 9. A connecting column 13 is fixedly connected to the right side of the slider 10. An air squeezing block 14 is fixedly connected to the right side of the connecting column 13. The lower surface of the air squeezing groove 12 is fixedly communicated with an air outlet groove 15. The upper surface inside the air outlet groove 15 is rotatably connected with a gas blocking plate 16 through a rotating shaft. A plurality of first springs 17 are fixedly connected between the upper surface of the gas blocking plate 16 and the air outlet groove 15. A gas release groove 18 is formed below the sliding groove 9. A blocking frame 19 is slidably connected to the inner side wall of the gas release groove 18. Sliding grooves 20 are symmetrically formed on the lower surface of the blocking frame 19. Support blocks 21 are slidably connected inside the sliding grooves 20 respectively. Second springs 34 are fixedly connected between the support blocks 21 and the sliding grooves 20. The right end inside the air squeezing groove 12 is fixedly communicated with the gas release groove 18. A sliding cavity 101 is formed inside the slider 10. A sliding plate 102 is slidably connected inside the sliding cavity 101. An extrusion frame column 103 is fixedly connected to the lower surface of the sliding plate 102. A fourth spring 104 is wound around the outer side wall of the extrusion frame column 103. The bottom end of the fourth spring 104 is fixedly connected to the lower surface inside the sliding cavity 101. The top end of the fourth spring 104 is fixedly connected to the lower surface of the sliding plate 102. An out-column opening 105 is formed on the lower surface inside the sliding cavity 101. An extrusion vertical plate 106 is fixedly connected to the upper surface of the sliding plate 102. The top end of the extrusion vertical plate 106 penetrates to the top end of the sliding cavity 101 and is fixedly connected with a pressing plate 107;

[0029] The extrusion vertical plate 106 and the pressing plate 107 are also in the state of not being pressed. When it is necessary to engage the circuit board, the slider 10 is pushed to slide to the right in the chute 9. At this time, the connecting column 13 on the right side of the slider 10 drives the air extrusion block 14 to move to the right in the air extrusion groove 12, squeezing the air in the air extrusion groove 12, so that the air pressure in the air extrusion groove 12 gradually increases. As the air pressure in the air extrusion groove 12 increases, when the pressure reaches a certain level, the air pressure will overcome the elastic force of the first spring 17 and push the air blocking plate 16 to rotate around the rotating shaft, opening the air outlet groove 15. At this time, the air in the air extrusion groove 12 is discharged through the air outlet groove 15, and the slider 10 continues to slide to the right. The card slot 8 and the card board cavity 11 engage the circuit board. After the engaging operation is completed, no gas enters the air outlet groove 15, and the first spring 17 will close the air outlet groove 15. At this time, the slider 10 is fixed, realizing the function of engaging the circuit board. If it is necessary to further fix or adjust the slider 10, the pressing plate 107 can be pressed. The pressing plate 107 drives the extrusion vertical plate 106 to move downward, and the extrusion vertical plate 106 pushes the sliding plate 102 to slide downward in the sliding cavity 101. When the sliding plate 102 moves downward, it drives the extrusion support column 103 to move downward through the column outlet 105. At this time, the set extrusion support column 103 will slide downward and contact the set blocking support 19, causing the blocking support 19 to move downward. At this time, the blocking support 19 cannot block the connection between the air release groove 18 and the air extrusion groove 12, and the gas will flow out. When the slider 10 is pulled to the left at this time, the circuit board can be taken out. Through the coordinated action of each component, the whole device realizes functions such as engaging, fixing, adjusting, and releasing the engagement, providing a reliable solution for specific working scenarios.

[0030] As Figures 1-7 shown, the front end of the lower surface of the base 1 is fixedly connected with a hollow square cavity 22. A rotating rod 23 is rotatably connected inside the hollow square cavity 22. The rear end of the rotating rod 23 is fixedly connected with a turntable 24. Wedge-shaped blocks 25 are symmetrically and fixedly connected to the outer side wall of the turntable 24. A transmission tooth 26 is fixedly connected to the rear surface of the wedge-shaped block 25. A gear 27 is fixedly connected to the lower surface of the rotating column 4. The gear 27 is meshed with the transmission tooth 26. A plurality of locking holes 28 are opened on the front surface of the hollow square cavity 22. The front end of the rotating rod 23 is fixedly connected with a connecting plate with holes 30. A locking column 29 is rotatably connected inside the connecting plate with holes 30. The locking column 29 includes a circular cavity 201. An outer cavity 202 is fixedly connected to the outer side wall of the circular cavity 201. A sliding circular plate 203 is slidably connected inside the outer cavity 202. A locking cavity 204 is fixedly connected to the rear surface of the sliding circular plate 203. An air suction circular plate 205 is slidably connected inside the circular cavity 201. An extrusion circular rod 206 is fixedly connected to the front surface of the air suction circular plate 205. The front end of the extrusion circular rod 206 penetrates into the inside of the circular cavity 201. A third spring 208 is fixedly connected between the front end of the extrusion circular rod 206 and the rear surface inside the circular cavity 201. The circular cavity 201 is fixedly communicated with the outer cavity 202;

[0031] In the initial state, the locking post 29 is engaged with the locking hole 28 for locking, the rotating rod 23 cannot rotate freely, and the rotating column 4 is in a non-rotatable state. When the angle of the positioning plate 6 needs to be adjusted, the extrusion round rod 206 on the locking post 29 is pressed. The extrusion round rod 206 pushes the air suction round plate 205 to slide forward in the round cavity 201. Since the round cavity 201 is fixedly connected to the outer cavity 202, the movement of the air suction round plate 205 changes the air pressure in the round cavity 201 and the outer cavity 202, generating negative pressure. The negative pressure attracts the sliding round plate 203 to move backward, and the sliding round plate 203 drives the locking cavity 204 to move forward. At this time, the locking cavity 204 is separated from the locking hole 28, unlocking the rotating rod 23. When the pressed extrusion round rod 206 is released, the rotating rod 23 is locked. Since the gear 27 on the lower surface of the rotating column 4 is engaged with the transmission tooth 26 on the turntable 24, the rotating column 4 is also locked, thus fixing the angle of the positioning plate 6. When the angle of the positioning plate 6 needs to be adjusted again, the angle of the positioning plate 6 can be adjusted manually by rotating the turntable 24 according to the above steps, so that the locking cavity 204 is engaged with the positions of different locking holes 28, realizing the function of adjusting the position of the positioning plate 6;

[0032] As Figure 5 and Figure 6 shown, an elastic groove 301 is opened on the right side inside the card slot 8. An air extrusion plate 302 is slidably connected inside the elastic groove 301. A cross plate 303 is fixedly connected to the left side of the air extrusion plate 302. An extrusion plate 304 is fixedly connected to the left side of the cross plate 303. A spring five 305 is fixedly connected between the air extrusion plate 302 and the right side inside the elastic groove 301. A locking sliding groove 306 is opened on the right side inside the positioning plate 6. A wedge-shaped slider 307 is slidably connected inside the locking sliding groove 306. A spring six 311 is fixedly connected between the upper surface of the wedge-shaped slider 307 and the upper surface inside the locking sliding groove 306. A cylinder 308 is fixedly connected to the lower surface of the wedge-shaped slider 307. The bottom end of the cylinder 308 penetrates to the outside of the locking sliding groove 306 and is fixedly connected to a positioning post 310. An extrusion groove 309 is opened on the left side inside the locking sliding groove 306. A cross wedge plate 313 is slidably connected inside the extrusion groove 309. The extrusion groove 309 is communicated with the elastic groove 301. On the upper surface of the base 1, a plurality of positioning grooves 312 are symmetrically opened. The inside of the positioning grooves 312 is engaged with the bottom end of the positioning post 310;

[0033] The spring five 305 is in a natural stretched state, pushing the air squeezing plate 302 against the right side position of the spring groove 301. At this time, the cross plate 303 and the extrusion plate 304 are also in their initial positions. The spring six 311 is also in a natural stretched state. The wedge-shaped slider 307 is near the upper position in the locking chute 306, and the positioning post 310 is engaged with the positioning groove 312 on the base 1. When the circuit board is placed in the card slot 8, the right edge of the circuit board will contact the extrusion plate 304. The circuit board pushes the extrusion plate 304 to move to the right, and the extrusion plate 304 drives the cross plate 303 to move to the right together, and then pushes the air squeezing plate 302 to slide to the right in the spring groove 301. During the process of the air squeezing plate 302 sliding to the right, the spring five 305 is compressed. The air squeezing plate 302 moves to the right, squeezing the air in the spring groove 301 into the extrusion groove 309 connected thereto. The air entering the extrusion groove 309 pushes the cross wedge plate 313 to slide to the right in the extrusion groove 309. Since the cross wedge plate 313 contacts the inclined surface of the wedge-shaped slider 307, the cross wedge plate 313 sliding to the right will squeeze the wedge-shaped slider 307. Under the action of the squeezing force, the wedge-shaped slider 307 slides upward in the locking chute 306 against the elastic force of the spring six 311. The upward sliding of the wedge-shaped slider 307 drives the cylinder 308 to move upward until the positioning post 310 disengages from the positioning groove 312 on the base 1. At this time, the positioning plate 6 can be rotated, that is, it can be realized that only when the circuit board on the positioning plate 6 is engaged and fixed can it be rotated, preventing the device from rotating when the engagement is not tight enough, causing the circuit board to fall off.

[0034] As Figure 1 shown, the lower surface of the base 1 is symmetrically and fixedly connected with support seats 31;

[0035] The symmetrically distributed support seats 31 enable the device to maintain balance when placed on a plane, effectively preventing the device from tilting or shaking due to unstable center of gravity. The firm connection between the support seats 31 and the base 1 ensures that during the operation of the device, it can withstand various forces without loosening or damage.

[0036] As Figure 6 shown, the front end of the extrusion round rod 206 is fixedly connected with a pressing round block 32;

[0037] When it is necessary to lock the angle of the rotating column 4, the user can push the extrusion round rod 206 to slide in the round cavity 201 by pressing the pressing round block 32. The larger pressing round block 32 makes the operation more labor-saving, and at the same time improves the accuracy and stability of the operation. In terms of appearance, the pressing round block 32 can be designed to be coordinated with the style of the whole device, increasing the aesthetic property of the device Supplementary description.

[0038] As Figure 1 shown, a dust cover 33 is engaged and connected to the upper surface of the positioning plate 6;

[0039] The dust cover 33 that is snap - connected to the upper surface of the positioning plate 6 plays an important protective role. The dust cover 33 is usually made of durable materials, and its size matches that of the positioning plate 6, and it can closely cover the upper surface of the positioning plate 6. The dust cover 33 can effectively prevent dust, debris, etc. from entering various components and structures on the positioning plate 6. When the device is not in use or in an idle state, the dust cover 33 can protect components such as the clamping block 7, the clamping groove 8, the sliding groove 9, the sliding block 10, and the clamping plate cavity 11 from being polluted by the external environment, extend the service life of the device, and ensure that the device can operate normally when used next time.

[0040] The above - described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
