Description

A circuit board processing clamp and method thereof that facilitates balancing

Technical Field

The present invention relates to the technical field of circuit board holders, and in particular to a circuit board processing holder and a method thereof which is easy to balance.

Background Art

Background technology of a circuit board processing clamp that is easy to balance involves ensuring the stability and accuracy of the circuit board during processing. Traditional clamps may have uneven clamping force when fixing the circuit board, causing deformation or damage to the board. Modern clamp designs achieve uniform distribution of clamping force by optimizing the clamp structure, thereby improving processing accuracy and board protection.

The patent with patent announcement number CN221531777U relates to the technical field of circuit board clamps. The circuit board processing clamp that is easy to balance includes a clamping base plate, and the upper surface of the clamping base plate is provided with two limit slide grooves. The upper surface of the clamping base plate is slidably connected to two support plates, and the lower surfaces of the two support plates respectively extend into the interior of the two limit slide grooves and are slidably connected to the limit slide grooves. Two limit slide rods are fixedly connected to the adjacent side surfaces of the two support plates, and two displacement plates are slidably sleeved on the outer surfaces of the two limit slide rods. The circuit board can be supported by the support column and the support ring to avoid bending of the circuit board due to pressure. At the same time, when adjusting the position of the support assembly, it can be observed through the upper displacement plate to avoid the problem that there is no obvious indicator on the top, which causes the support assembly to be not directly below the installation position, thereby resulting in poor support effect.

In the above patent, observation can be made through the displacement plate above to avoid problems such as the support component not being directly below the installation position due to the lack of obvious indicators above, which in turn leads to poor support effect. However, the current measuring equipment has the following problems: a clamping device without an anti-pinching mechanism may cause the clamp to exert excessive pressure on the circuit board, increasing the risk of damaging the board during operation; processing or testing in which the circuit board cannot be rotated after clamping will force the operator to operate at a fixed angle. If it is necessary to operate on different surfaces or different angles of the board, the operator will face great inconvenience.

A method for using a circuit board processing clamp that is easy to balance includes the following steps:

Step 1: First, place the circuit board on the placement plate, move the clamping device on the right side by moving the fixing frame 1, and complete the initial fixation of the circuit board through the circuit board and the clamping block, and drive the pressing plate to clamp the circuit board by moving the clamping plate downward. When the clamping force is too large, the movement of the clamping plate is limited by the T-shaped block to prevent damage to the circuit board caused by excessive clamping;

Step 2: After the clamping device has finished clamping, the circuit board is rotated by rotating the rotating rod, and the rotation of the rotating rod is limited by the limit block to prevent it from reversing and maintain the stability of the rotation of the circuit board. The electric push rod drives the support block to support the bottom of the circuit board. Because the components on the surface of the circuit board are of different heights, the support block can be contacted with the component to drive the gear to change the moving position of the support block on the other side, so as to prevent bumps caused by different heights of components;

Step 3: Move the fixed end of the electric push rod to drive the card slot to move, and fix the fixed end of the electric push rod through the plug block to prevent the circuit board from colliding with the supporting device during rotation. Pressing down the latch can release the restriction of the plug block on the fixed end of the electric push rod, which can reduce operation time and improve work efficiency.

The present invention provides a circuit board processing clamp and method thereof which is easy to balance. It has the following beneficial effects:

(1) The invention places the circuit board on the placement plate by setting a clamping device, and drives the clamping device on the right side to move by rotating motor 1 in cooperation with screw rod 1, spiral groove 1, moving block and fixed frame 1. At this time, the two sides of the circuit board are initially fixed by the clamping block and spring No. 1. At this time, the circuit board is clamped by rotating motor 2 in cooperation with screw rod 2, spiral groove 2, clamping plate, penetration rod and pressure plate. When the clamping force is too large, the pressure plate is forced to move upward in cooperation with the penetration rod, spring No. 2, fixed rod, slider, T-block and limit groove, so that the clamping plate cannot continue to clamp downward. By moving the clamping plate upward in cooperation with the T-block and limit groove, the circuit board loses the clamping effect, thereby preventing physical damage to the circuit board during the clamping process, such as breakage, scratches or circuit short circuit. The circuit board is rotated by rotating the rotating rod in cooperation with the placement plate. During the assembly and welding process, the rotating plate can make it easier for operators to reach different parts of the circuit board, thereby improving the comfort and efficiency of the operation.

(2) The invention, through the setting of the supporting device, prevents the rotating rod from rotating by cooperating with the square groove and the limit block, and allows the rotating rod to rotate normally by moving the limit block to cooperate with the T-shaped rod and the square groove, thereby preventing accidental reversal during rotation, maintaining stability when clamping the circuit board, and reducing errors or damage caused by position changes. After the clamping device completes clamping, the bottom of the circuit board is supported by moving the electric push rod to cooperate with the connecting frame, connecting button, gear, rack, slide bar and support block to maintain the balance of the circuit board. The support can prevent the circuit board from bending or deforming due to its own weight when suspended in the air, and maintain its flatness and structural stability. There are many components of different heights on the surface of the circuit board. At this time, the support block contacts the support block so that the support block moves downward to cooperate with the slide bar, rack and gear so that the slide bar on the other side can adjust the position of contact with the component through the gear pair, thereby preventing damage to the component caused by collision due to different heights of the component.

(3) The invention, through the setting of auxiliary devices, fixes the support device through the electric push rod in conjunction with the card slot, the plug block, the hollow block and the No. 5 spring, thereby preventing the circuit board from contacting the support device during rotation and causing collisions and wear of the circuit board. If the fixation needs to be released, the support device can be removed by pressing down the pin in conjunction with the sliding block, the U-shaped block, the No. 5 spring, the plug block and the card slot, thereby reducing the operation time and improving the overall work efficiency.

Please refer to Figures 1 to 7. Based on the above embodiments, in another embodiment of the present invention, a balancing device and an auxiliary device are arranged above the base 1.

The balancing device also includes a fixing button 22, an electric push rod 23 and a connecting frame 24. The fixing button 22 is fixedly installed on the top of the base 1, the fixed end of the electric push rod 23 is rotatably installed on the outer wall of the fixing button 22, and the connecting frame 24 is fixedly installed on the fixed end of the electric push rod 23, so that the support device can be height-adjusted.

The balancing device also includes a slide bar 25, a support block 26, a connecting button 27 and a gear 28. The slide bar 25 is slidably mounted on the inner wall of the connecting frame 24, the support block 26 is fixedly mounted on the top of the slide bar 25, the connecting button 27 is fixedly mounted on the output end of the electric push rod 23, and the gear 28 is rotatably mounted on the inner wall of the connecting button 27. A rack is provided on the surface of the slide bar 25, and the rack is meshed with the gear 28 to support the bottom of the circuit board so as to maintain the balance of the circuit board. The support can prevent the circuit board from bending or deforming due to its own weight when suspended in the air, thereby maintaining its flatness and structural stability.

The auxiliary device includes a slot 30, a hollow block 31, an insert block 32, a U-shaped block 33 and a No. 5 spring 34. The slot 30 is fixedly installed on the fixed end of the electric push rod 23, the hollow block 31 is fixedly installed on the top of the base 1, the insert block 32 is slidably installed on the inner wall of the hollow block 31, the U-shaped block 33 is slidably installed on the inner wall of the hollow block 31, and the No. 5 spring 34 is arranged between the insert block 32 and the U-shaped block 33.

The latch 36 is reset by the arranged No. 6 spring, and the supporting device can be removed, which can reduce the operation time and improve the overall work efficiency.

A method for using a circuit board processing clamp that is easy to balance includes the following steps:

Step 1: First, place the circuit board on the placement plate 15, move the clamping device on the right side by moving the fixing frame 13, and complete the preliminary fixation of the circuit board through the circuit board and the clamping block 16, and drive the pressing plate 112 to clamp the circuit board by moving the clamping plate 110 downward, and limit the movement of the clamping plate 110 by the T-shaped block 115 when the clamping force is too large to prevent damage to the circuit board caused by excessive clamping;

Step 2: After the clamping device has finished clamping, the circuit board is rotated by rotating the rotating rod 118, and the rotation of the rotating rod 118 is limited by the limit block 21 to prevent it from reversing and maintain the stability of the rotation of the circuit board. The electric push rod 23 drives the support block 26 to support the bottom of the circuit board. Because the components on the surface of the circuit board are of different heights, the support block 26 can contact the components to drive the gear 28 to change the moving position of the support block 26 on the other side, so as to prevent bumps caused by different heights of components;

Step three: Move the fixed end of the electric push rod 23 to drive the card slot 30 to move, and fix the fixed end of the electric push rod 23 through the plug block 32 to prevent the circuit board from colliding with the supporting device during rotation. Pressing down the latch 36 can release the restriction of the plug block 32 on the fixed end of the electric push rod 23, which can reduce operation time and improve work efficiency.

When the present embodiment is working, the square slot is rotated by the rotation of the rotating rod 118, so that when the rotation stops, the limit block 21 is inserted into the square slot. At this time, the rotating rod 118 cannot rotate, and the limit block 21 is moved to fit with the T-shaped rod 20 so that the limit block 21 is out of the square slot. At this time, the rotating rod 118 can rotate normally to prevent accidental reversal during the rotation process, maintain the stability when clamping the circuit board, and reduce errors or damage caused by position changes. After the clamping device is clamped, the connecting frame 24 is driven to move by moving the fixed end of the electric push rod 23 until it is parallel to the circuit board. At this time, the connecting button 27 is driven to move by the output end of the electric push rod 23, and the movement of the connecting button 27 drives the gear 28 to move. The movement of gear 28 causes the rack to move, the movement of the rack drives the slide bar 25 to move, the movement of the slide bar 25 drives the support block 26 to move, and the bottom of the circuit board is supported to keep the balance of the circuit board. The support can prevent the circuit board from bending or deforming due to its own weight when it is suspended in the air, and maintain its flatness and structural stability. There are many components of different heights on the surface of the circuit board. At this time, the support block 26 contacts with it, causing the support block 26 to move downward, and the movement of the support block 26 drives the slide bar 25 to move, and the movement of the slide bar 25 drives the rack to move. The movement of the rack causes the gear 28 to rotate, so that the slide bar 25 on the other side can adjust the position of the contact with the component through the gear 28, and prevent the component from being damaged due to collision caused by different heights of the components;

The fixed end of the electric push rod 23 drives the slot 30 to move, and the movement of the slot 30 will contact the inclined surface of the plug block 32, causing the plug block 32 to move to the right side of the hollow block 31, and at the same time compress the No. 5 spring 34. When the inner wall of the slot 30 and the plug block 32 are at the same level, the No. 5 spring 34 is released and drives the plug block 32 to insert into the inner wall of the slot 30, thereby fixing the support device to prevent the circuit board from contacting the support device during rotation and causing a bump and wear of the circuit board. If the fixation needs to be released, the latch 36 is pressed down to make it contact with the inclined surface of the sliding block 35, so that the sliding block 35 moves to the right. The movement of the sliding block 35 drives the U-shaped block 33 to move, and the movement of the U-shaped block 33 will stretch the No. 5 spring 34. When the No. 5 spring 34 is stretched to a certain extent, it drives the plug block 32 to move away from the inner wall of the slot 30. At this time, the support device can be removed, which can reduce the operation time and improve the overall work efficiency.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
