Description

Technical Field

[0001] The invention relates to the field of circuit board processing, and in particular to a positioning component for circuit board processing. Background Art

[0002] A circuit board can be called a printed circuit board or a printed circuit board. When processing a circuit board, a positioning device is generally required to fix it. The existing positioning device for circuit board processing has a relatively low efficiency in fixing the circuit board, and the operation is relatively cumbersome for users.

[0003] Specifically, a Chinese patent with patent number CN218103676U discloses a positioning device for circuit board processing. The device still has some obvious shortcomings in actual use, such as: the circuit board is clamped and fixed on the placement table by the positioning structure around it, and the bottom of the circuit board fits tightly with the top of the placement table. In this way, when welding the direct-insertion devices and shoe electronic components, the contact between the circuit board and the placement table cannot be welded, which directly affects the processing efficiency of the circuit board. Summary of the invention

[0004] The purpose of the present invention is to provide a positioning assembly for circuit board processing.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A positioning assembly for circuit board processing comprises a base, mounting plates are arranged on both sides of the base, and a rotatable positioning mechanism is arranged between two sets of mounting plates:

[0007] The camming mechanism comprises a cylinder driven by a motor, wherein four groups of strip grooves are axially arranged on the outer wall of the cylinder, and a clamping plate is radially arranged on the outer wall of the cylinder on both sides of the strip grooves, and a clamping groove corresponding to the strip groove is arranged on one side wall of the clamping plate, and mounting plates located between two adjacent groups of strip grooves are arranged on the upper and lower sides of the cylinder, and pressure rods corresponding to the clamping plates are arranged at both ends of the mounting plate, and sliding openings for the corresponding pressure rod ends to pass through are arranged on the side walls of the clamping plate, and the sliding openings are connected with the corresponding slot openings, and the pressure rod ends extend into the corresponding slots, and a sliding cavity is also vertically arranged in the cylinder, and through holes connected with the sliding cavity are arranged at the upper and lower ends of the cylinder, and a vertical rod passing through the through hole and extending into the sliding cavity is arranged on the mounting plate, and a protrusion is arranged on the end of the vertical rod in the sliding cavity, and a spring is also sheathed on the vertical rod in the sliding cavity.

[0008] Preferably, an electromagnet driven by a hydraulic rod is arranged directly above the cylinder, and the electromagnet is directly opposite to the mounting plate above.

[0009] Preferably, the two groups of protrusions in the sliding cavity are respectively an N-pole magnetic block and an S-pole magnetic block, wherein the N-pole magnetic block and the S-pole magnetic block are magnetically connected and fixed, and an antimagnetic coating is provided on the inner wall of the sliding cavity.

[0010] Preferably, four groups of strip grooves are evenly arranged on the outer wall of the cylinder, the width of the card slot is equal to the width of the strip groove, one end of the card slot is connected to the corresponding strip groove, and the other end of the card slot is connected to the outer space of the card plate.

[0011] Preferably, a metal block facing the electromagnet is arranged on the mounting plate, and a finger groove is arranged on the end surface of the metal block.

[0012] The beneficial effects of the present invention are as follows: the present invention compresses the spring by pulling the mounting plate, the vertical rod and the protrusion, thereby driving the pressure rod to slide upward in the sliding opening, thereby facilitating the insertion of the circuit board into the strip groove and the card slot for fixing; and when the spring is stretched, the pressure rod can be driven to move downward in the sliding opening through the protrusion, the vertical rod and the mounting plate, thereby locking the circuit board located in the card slot and the strip groove, so that the circuit board will not slip from the above components during the flipping process, and at the same time, the cylinder is driven by a motor to rotate the circuit board, so that workers on different sides can sequentially process different end surfaces of the circuit board, and can also remove the processed products rotated above the cylinder and replace them with new products, so that workers can continuously process the products, so that the placement and processing of the circuit board are streamlined, thereby improving its processing efficiency.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] A positioning assembly for circuit board processing includes a base 1, mounting plates 2 are arranged on both sides of the base 1, and a rotatable positioning mechanism 3 is arranged between two sets of mounting plates 2:

[0020] The positioning mechanism 3 includes a cylinder 4 driven by a motor 5, four groups of strip grooves 6 are axially arranged on the outer wall of the cylinder 4, and clamping plates 7 are radially arranged on the outer wall of the cylinder 4 on both sides of the strip grooves 6. A clamping groove 8 corresponding to the strip grooves 6 is arranged on one side wall of the clamping plate 7. In the present invention, the four groups of strip grooves 6 are evenly arranged on the outer wall of the cylinder 4, and the width of the clamping groove 8 is equal to the width of the strip groove 6. One end of the clamping groove 8 is connected to the corresponding strip groove 6, and the other end of the clamping groove 8 is connected to the outer space of the clamping plate 7;

[0021] The cylindrical body 4 is provided with mounting plates 9 located between two adjacent groups of strip grooves 6 on both upper and lower sides, and pressure rods 10 corresponding to the card plates 7 are provided at both ends of the mounting plates 9. A sliding opening 11 for the corresponding end of the pressure rod 10 to pass through is provided on the side wall of the card plate 7. The sliding opening 11 is connected with the corresponding card slot 8 opening, and the end of the pressure rod 10 extends into the corresponding card slot 8. A sliding cavity 12 is also vertically provided in the cylindrical body 4, and through holes connected with the sliding cavity 12 are provided at both upper and lower ends of the cylindrical body 4. A vertical rod 13 passing through the through hole and extending into the sliding cavity 12 is provided on the mounting plate 9, and a protrusion 18 is provided on the end of the vertical rod 13 in the sliding cavity 12, and a spring 14 is also jacketed on the vertical rod 13 in the sliding cavity 12.

[0022] In this embodiment, an electromagnet 16 driven by a hydraulic rod 15 is arranged directly above the cylinder 4, and the electromagnet 16 is directly opposite to the upper mounting plate 9. A metal block 17 is arranged on the mounting plate 9 and is directly opposite to the electromagnet 16. A finger groove is arranged on the end surface of the metal block 17.

[0023] In this embodiment, the two groups of protrusions 18 in the sliding cavity 12 are respectively an N-pole magnetic block and an S-pole magnetic block, wherein the N-pole magnetic block and the S-pole magnetic block are magnetically connected and fixed, and an antimagnetic coating is provided on the inner wall of the sliding cavity 12.

[0024] When in use, the hydraulic rod 15 drives the electromagnet 16 to move downward and contact the upper metal block 17, and at the same time, the power is turned on to make the electromagnet 16 and the metal block 17 magnetically connected, wherein the hydraulic rod 15 pulls the upper metal block 17, the mounting plate 9 and the pressure rod 10 upward through the electromagnet 16, and at this time the pressure rod 10 slides upward in the corresponding sliding opening 11, and at this time the mounting plate 9 drives the vertical rod 13 to move upward in the sliding cavity 12 and compresses the corresponding spring 14 through the protrusion 18, thereby forcing the upper and lower groups of magnetic material protrusions 18 to separate, and then the circuit board can be inserted into the upper two groups of strip grooves 6 for fixing, and at the same time the two ends of the circuit board slide into the corresponding card plate 7 The circuit board is fixed in the card slot 8, thereby fixing the circuit board. At the same time, the hydraulic rod 15 stretches to drive the mounting plate 9, the pressure rod 10 and other components to move downward. When the electromagnet 16 is powered off and loses its pulling force with the hydraulic rod 15, the upper spring 14 stretches and pushes the corresponding vertical rod 13 to drive the mounting plate 9 to move downward, and the downwardly moved upper mounting plate 9 drives the pressure rod 10 to slide downward in the corresponding sliding opening 11 and abut against one end surface of the circuit board in the card slot 8, thereby locking and fixing the circuit board in the card slot 8 and the strip groove 6, preventing the circuit board from sliding out of the card slot 8 and the strip groove 6 when it is subsequently flipped to the bottom of the cylinder 4.

[0025] Then the motor 5 drives the cylinder 4 to rotate the strip groove 6, the card plate 7 and the circuit board fixed by the two, so that the staff on the right can process the front side of the circuit board located at the top at this time, and when the circuit board rotates to the left, the staff on the left can process the back side of the circuit board located at the top at this time, so as to realize the assembly line processing of the two end surfaces of the circuit board. When the two groups of circuit boards fixed by the same group of mounting plates 9 and corresponding pressure rods 10 are displaced to the top of the cylinder 4, the electromagnet 16 driven by the hydraulic rod 15 can be moved down to magnetically connect with the metal block 17, thereby pulling the vertical rod 13 and the protrusion 18 to compress the spring 14. At the same time, the mounting plate 9 drives the pressure rod 10 to move up in the sliding opening 11. In the absence of the squeezing of the pressure rod 10, it is convenient for people to take out the products located in the card groove 8 and the strip groove 6 and replace the new circuit board to be processed for fixing. Then the motor 5 drives the cylinder 4 to drive the card plate 7 and the circuit board to continue to rotate.

[0026] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
