Technical Field

[0001] The invention relates to circuit board processing positioning, in particular to a circuit board processing positioning seat. Background Art

[0002] In modern industrial production and scientific research, there is an increasing demand for positioning and angle adjustment of objects. Traditional positioning devices often have problems such as inconvenient angle adjustment, loose fixation, and complicated operation. For example, some positioning devices require the use of complex tools and cumbersome steps when adjusting the angle, which not only wastes time but also may result in low adjustment accuracy. Moreover, the fixing method of traditional devices may not be stable enough and is prone to displacement when subjected to external forces, affecting the accuracy and safety of the work;

[0014] Furthermore, a dust cover is snap-fitted and connected to the upper surface of the positioning plate.

[0015] Beneficial effects: The device achieves precise adjustment and stable fixation of the positioning plate angle through ingenious structural design. The coordination of the turntable, turnbar, wedge block, transmission teeth and the gear under the turn column allows the user to easily adjust the positioning plate angle according to actual needs. The presence 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 in the assembly of precision instruments, positioning in industrial production, or in laboratory operations, 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; and stable fixation can ensure that there will be no accidental movement during operation, ensuring production safety;

[0016] The coordination of the card block, card slot, slider and card plate cavity realizes quick connection and fixation, providing convenience for various operations. At the same time, the sliding of the slider in the slide slot and the related extrusion and deflation structures make the engagement operation flexible and controllable. In addition, the pressing round block at the front end of the extruded round rod increases the operating area, making the operation of locking and unlocking the rotating column angle more convenient. This design greatly improves work efficiency and reduces operation time and labor costs. In some work scenarios where workpieces need to be frequently replaced or adjusted, the convenient operation advantage of the device is particularly obvious, which can quickly adapt to different work requirements and improve production efficiency.

At the same time, the spring six is ​​also in a naturally extended state. The wedge-shaped slider is in a position close to the upper side of the locking slot. The positioning column is engaged with the positioning slot on the base, ensuring the stability of the device when the circuit board is not placed. When the circuit board is placed in the 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 the spring five and squeezing the air in the spring slot into the extrusion slot. In this process, the air entering the extrusion slot pushes the cross wedge plate to slide to the right. Since the cross wedge plate contacts the inclined surface of the wedge-shaped slider, the wedge slider is squeezed to overcome the elastic force of spring six and slide upward, driving the cylinder and the positioning column to move upward, realizing the disengagement of the positioning column from the positioning slot. The positioning plate can only be rotated after the circuit board is fixed by the clamping. This effectively prevents the risk of the circuit board falling due to rotation due to loose clamping, greatly improving the safety and reliability of the processing process.

DETAILED DESCRIPTION

[0028] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1

[0030] like Figure 1-7As shown, a circuit board processing positioning seat is provided, including a base 1, a rotating opening 2 is provided on the upper surface of the base 1, a rotating groove 3 is provided 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 wall of the rotating column 4, the limiting ring 5 is slidably connected to 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 provided on the left side of the clamping block 7, and a sliding groove 9 is provided on the left side of the upper surface of the positioning plate 6. The slide 9 is slidably connected to a slider 10, and a card 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 of the slide 9, and 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 connected to an air outlet groove 15, and the upper surface of the air outlet groove 15 is rotatably connected to an air baffle plate 16 through a rotating shaft. A plurality of springs are fixedly connected between the upper surface of the air baffle plate 16 and the air outlet groove 15. 17, a degassing groove 18 is provided below the slide 9, a retaining frame 19 is slidably connected to the inner wall of the degassing groove 18, a sliding groove 20 is symmetrically provided on the lower surface of the retaining frame 19, a support block 21 is slidably connected to the inside of the sliding groove 20, a spring 24 is fixedly connected between the support block 21 and the sliding groove 20, the right end of the inner part of the extrusion groove 12 is fixedly connected to the degassing groove 18, a sliding cavity 101 is provided inside the slider 10, a slide plate 102 is slidably connected to the inside of the slide cavity 101, and the slide plate 102 is fixedly connected to the inner part of the slide plate 102. The lower surface is fixedly connected with a squeeze column 103, and a spring 104 is wound around the outer wall of the squeeze column 103. The bottom end of the spring 104 is fixedly connected to the lower surface of the inner cavity 101, and the top of the spring 104 is fixedly connected to the lower surface of the slide plate 102. The inner upper surface of the slide cavity 101 is provided with a column outlet 105. The upper surface of the slide plate 102 is fixedly connected with an squeeze vertical plate 106. The top of the squeeze vertical plate 106 penetrates to the top of the slide cavity 101 and is fixedly connected with a pressing plate 107.

[0031] The squeezing vertical plate 106 and the pressing plate 107 are also in an unpressed state. When the circuit board needs to be clamped, the slider 10 is pushed to slide to the right in the slide groove 9. At this time, the connecting column 13 on the right side of the slider 10 drives the squeezing block 14 to move to the right in the squeezing groove 12, squeezing the air in the squeezing groove 12, so that the air pressure in the squeezing groove 12 gradually increases. As the air pressure in the squeezing groove 12 increases, when the pressure reaches a certain level, the air pressure will overcome the elastic force of the spring 17, push the air baffle 16 to rotate around the rotating shaft, and open the air outlet groove 15. At this time, the air in the squeezing groove 12 is discharged through the air outlet groove 15, and the slider 10 continues to slide to the right, and the clamping groove 8 and the clamping plate cavity 11 clamp the circuit board. After the clamping operation is completed, no gas enters the air outlet groove 15, and the spring 17 will close the air outlet groove 15. At this time, the slider 10 is fixed to achieve the function of clamping the circuit board. If the slider 10 needs to be further fixed or adjusted, the pressing plate 107 can be pressed. The pressing plate 107 drives the squeezing vertical plate 106 to move downward, and the squeezing vertical plate 106 pushes the slide plate 102 to slide downward in the slide cavity 101. When the slide plate 102 moves downward, it drives the squeezing frame column 103 to move downward through the column outlet 105. At this time, the squeezing frame column 103 will slide downward and contact the set blocking frame 19, so that the blocking frame 19 moves downward. At this time, the blocking frame 19 cannot block the connection between the air release groove 18 and the squeezing groove 12, and the gas will flow out. At this time, when the slider 10 is pulled to the left, the circuit board can be taken out. The entire device realizes the functions of engagement, fixing, adjustment and release of engagement through the coordinated action of various components, providing a reliable solution for specific work scenarios.

[0032] like Figure 1-7 As shown, the front end of the lower surface of the base 1 is fixedly connected with a hollow square cavity 22, the interior of the hollow square cavity 22 is rotatably connected with a rotating rod 23, the rear end of the rotating rod 23 is fixedly connected with a rotating disk 24, the outer wall of the rotating disk 24 is symmetrically fixedly connected with a wedge block 25, the rear surface of the wedge block 25 is fixedly connected with a transmission tooth 26, the lower surface of the rotating column 4 is fixedly connected with a gear 27, the gear 27 is meshed with the transmission tooth 26, the front surface of the hollow square cavity 22 is provided with a plurality of locking holes 28, the front end of the rotating rod 23 is fixedly connected with a connecting plate 30 with a hole, the interior of the connecting plate 30 with a hole is rotatably connected with a locking column 2 9. The locking column 29 includes a circular cavity 201, the outer wall of the circular cavity 201 is fixedly connected to the outer cavity 202, the inner part of the outer cavity 202 is slidably connected to the sliding circular plate 203, the rear surface of the sliding circular plate 203 is fixedly connected to the locking cavity 204, the inner part of the circular cavity 201 is slidably connected to the suction circular plate 205, the front surface of the suction circular plate 205 is fixedly connected to the extrusion circular rod 206, the front end of the extrusion circular rod 206 passes through the circular cavity 201, a spring 3 208 is fixedly connected between the extrusion circular rod 206 and the inner rear surface of the circular cavity 201, and the circular cavity 201 is fixedly connected to the outer cavity 202;

[0033] In the initial state, the locking column 29 is locked with the locking hole 28, 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 extruding round rod 206 on the locking column 29 is pressed. The extruding round rod 206 pushes the suction circular plate 205 to slide forward in the circular cavity 201. Since the circular cavity 201 and the outer cavity 202 are fixedly connected, the movement of the suction circular plate 205 causes the air pressure in the circular cavity 201 and the outer cavity 202 to change, generating negative pressure. The negative pressure attracts the sliding circular plate 203 to move backward, and the sliding circular plate 203 drives the locking cavity 204 to move forward. At this time, the locking cavity 204 is separated from the locking hole 28, and the rotating rod 23 is unlocked. When the pressed extruding round rod 206 is released, the rotating rod 23 is locked, and since the gear 27 on the lower surface of the rotating column 4 is meshed and connected with the transmission tooth 26 on the turntable 24, the rotating column 4 is also locked, thereby 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 again according to the above steps by manually rotating the turntable 24 so that the locking cavity 204 engages with the positions of different locking holes 28 to achieve the function of adjusting the position of the positioning plate 6;

[0034] like Figure 5 and Figure 6 As shown, a spring groove 301 is provided on the right side of the card slot 8, an air squeezing plate 302 is slidably connected to the inside of the spring groove 301, a horizontal plate 303 is fixedly connected to the left side of the air squeezing plate 302, an extrusion plate 304 is fixedly connected to the left side of the horizontal plate 303, a spring 5 305 is fixedly connected between the air squeezing plate 302 and the inner right side of the spring groove 301, a locking groove 306 is provided on the right side of the positioning plate 6, a wedge-shaped slider 307 is slidably connected to the inside of the locking groove 306, and the upper surface of the wedge-shaped slider 307 is connected to the inner upper surface of the locking groove 306. A spring 6 311 is fixedly connected, a cylinder 308 is fixedly connected to the lower surface of the wedge-shaped slider 307, the bottom end of the cylinder 308 passes through the locking slot 306, and is fixedly connected to a positioning column 310, an extrusion groove 309 is provided on the left side of the locking slot 306, a horizontal wedge plate 313 is slidably connected to the inside of the extrusion groove 309, the extrusion groove 309 is connected to the spring groove 301, and a plurality of positioning grooves 312 are symmetrically provided on the upper surface of the base 1 and the outer wall of the transfer port 2, and the inside of the positioning groove 312 is engaged with the bottom end of the positioning column 310;

[0035] The spring five 305 is in a naturally extended state, pushing the extrusion plate 302 to the right side of the spring slot 301. At this time, the horizontal plate 303 and the extrusion plate 304 are also in the initial position. The spring six 311 is also in a naturally extended state, the wedge-shaped slider 307 is close to the upper position in the locking slide slot 306, and the positioning column 310 is engaged with the positioning slot 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 rightward, and the extrusion plate 304 drives the horizontal plate 303 to move rightward together, thereby pushing the extrusion plate 302 to slide rightward in the spring slot 301. In the process of the extrusion plate 302 sliding to the right, the spring five 305 is compressed. The extrusion plate 302 moves to the right, squeezing the air in the spring slot 301 into the extrusion slot 309 connected thereto. The air entering the extrusion slot 309 pushes the horizontal wedge plate 313 to slide rightward in the extrusion slot 309. Since the horizontal wedge plate 313 contacts the inclined surface of the wedge slider 307, the horizontal wedge plate 313 slides rightward to squeeze the wedge slider 307. Under the action of the squeezing force, the wedge slider 307 overcomes the elastic force of the spring 6 311 and slides upward in the locking slide groove 306. The upward sliding of the wedge slider 307 drives the cylinder 308 to move upward until the positioning column 310 is disengaged from the positioning groove 312 on the base 1. Only then can the positioning plate 6 be rotated, and the circuit board on the positioning plate 6 can be rotated, so as to prevent the device from rotating when the clamping is not tight enough, causing the circuit board to fall off.

[0036] like Figure 1 As shown, a support seat 31 is symmetrically fixedly connected to the lower surface of the base 1;

[0037] The symmetrically distributed support base 31 enables 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 base 31 and the base 1 ensures that the device can withstand various forces without loosening or damage during operation.

[0038] like Figure 6 As shown, the front end of the extrusion round rod 206 is fixedly connected with a pressing round block 32;

[0039] When the angle of the rotating column 4 needs to be locked, the user can push the extruding rod 206 to slide in the circular cavity 201 by pressing the pressing round block 32. The larger pressing round block 32 makes the operation more labor-saving and also improves the accuracy and stability of the operation. In terms of appearance, the pressing round block 32 can be designed to coordinate with the style of the entire device and increase the aesthetics of the device.

[0040] like Figure 1 As shown, a dust cover 33 is snap-connected to the upper surface of the positioning plate 6;

[0041] The dust cover 33 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 the positioning plate 6, and can tightly 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 the device is in an idle state, the dust cover 33 can protect the card block 7, the card slot 8, the slide 9, the slider 10, the card plate cavity 11 and other components from being polluted by the external environment, extending the service life of the device and ensuring that the device can operate normally when it is used next time.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
