Description

Technical Field

[0001] This invention belongs to the field of circuit board manufacturing technology, and more specifically, relates to a positioning device for circuit board manufacturing. Background Technology

[0002] The use of positioning devices in the PCB manufacturing process is a key measure to ensure cutting accuracy and improve production yield and efficiency. The positioning device firmly fixes the PCB to be separated, avoiding displacement and shaking during the cutting process, and effectively preventing component damage and circuit breakage caused by misalignment. At the same time, it can eliminate human error in manual separation, ensuring that the dimensional accuracy of each sub-board is consistent, which is a necessary foundation for achieving high-precision mass production of PCBs.

[0003] The positioning devices currently used in PCB production still have the following problems: 1. When the PCB separation accuracy requirement is high and the separation blade is not sharp, the PCB cannot be automatically separated from the separation blade. The dull separation blade can easily affect the separation accuracy of the PCB; 2. It is inconvenient for staff to adjust the positioning mode appropriately according to the separation accuracy of the PCB. Under the premise of ensuring high separation accuracy, it is impossible to appropriately increase the service life of the separation blade; 3. Generally, there is a lack of elastic support structure, which makes the bottom of the PCB easy to be scratched when the PCB moves. Summary of the Invention

[0004] This disclosure relates to a positioning device for circuit board production, comprising a support positioning unit, a movable mounting unit, an automatic clamping unit, a precision adjustment unit, and an elastic support unit. Two circular support rods automatically slide along the inclined surfaces of two inclined support blocks, automatically separating the circuit board to be separated from the separating blade. When the circuit board separation precision requirement is not high, the left ends of two circular limit pins are inserted into two limit holes, allowing the separating blade to continue to be used for a period of time even if it is not sharp initially. Two rows of elastic support wheels provide auxiliary support for the moving circuit board, automatically separating the bottom of the circuit board from the clamping and positioning frame, preventing the clamping and positioning frame from scratching the circuit board. This solves the problems that dull separating blades can easily affect the separation precision of the circuit board, make it inconvenient for workers to adjust the positioning mode according to the separation precision of the circuit board, and easily cause scratches on the bottom of the circuit board when it moves.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In this invention, the movable mounting block can slide along the support positioning seat. When the depanel blade is sharp and does not need to be replaced, the movable mounting block remains stationary under the elastic limiting action of the positioning groove and the movable positioning head. When the depanel blade is dull and needs to be replaced, the movable mounting block cannot remain stationary under the elastic limiting action of the positioning groove and the movable positioning head. The movable positioning head slides downward after being subjected to force, and the movable mounting block slides automatically along the depaneling direction. This avoids excessive resistance between the depanel blade and the circuit board, thus ensuring the depaneling accuracy of the circuit board.

[0016] 2. In this invention, when the output shafts of the two clamping cylinders extend, the two protective contact pads automatically press the circuit board to be separated, and the clamping positioning frame can slide between the two rectangular limiting frames; In addition, when the movable mounting block slides automatically along the separation direction, the two circular support rods also slide automatically along the inclined surfaces of the two inclined support blocks, so that the circuit board to be separated is automatically separated from the separation blade; when the control switch is pressed, the intelligent controller controls the alarm to work, which can remind the staff to replace the separation blade in time.

[0017] 3. In this invention, the movable limiting bracket restricts the sliding distance of the movable mounting block, preventing it from detaching from the support positioning seat. When the circuit board separation accuracy requirement is high, the two circular limiting pins are separated from the two limiting holes, ensuring that the movable mounting block has a sliding function. When the circuit board separation accuracy requirement is not high, the operator can use a wrench to rotate the adjusting screw so that the left ends of the two circular limiting pins are inserted into the two limiting holes, ensuring that the movable mounting block does not have a sliding function, extending the service life of the separation blade, and allowing the separation blade to continue to be used for a period of time even if it is not sharp in the early stage.

[0018] 4. In this invention, the two rows of elastic support wheels provide auxiliary support for the moving circuit board, causing the bottom of the circuit board to automatically separate from the clamping and positioning frame, thus preventing the clamping and positioning frame from scratching the circuit board; when the output shafts of the two clamping cylinders extend, the circuit board drives the two rows of elastic support wheels to move downward, so that the bottom of the circuit board contacts the clamping and positioning frame.
