Description

Technical Field

[0001] The invention belongs to the technical field of printed circuit board pressing, in particular to a pressing assembly for printed circuit board processing. Background Art

[0002] Printed circuit boards are electronic components that use organic materials or inorganic substrates to wire, embed or mount components to achieve electrical connections and realize functions. When processing printed circuit boards, their surfaces need to be glued. In order to avoid deviations during the gluing process, the circuit boards need to be pressed and fixed.

[0003] The patent with the announcement number CN221178025U discloses a clamping assembly for printed circuit board processing, which relates to the field of printed circuit board clamping technology, and includes a base, the upper surface of the base is fixedly connected to a support platform, the upper surface of the base and the back of the support platform is fixedly connected to a fixed horizontal column, and the left side of the fixed horizontal column is fixedly connected to a fixed column. The patent starts the second motor to rotate the threaded rod fixedly connected to the right side of the second motor, so that the slider 1 threadedly sleeved on the outer wall of the threaded rod moves to the right, so that the movable column moves to the right under the action of the fixed horizontal bar, so that the fixing device is adjusted according to the size of the printed circuit board, and the gear 1 fixedly connected to the lower surface of the motor is rotated by the action of the first motor, so that the gear 2 is rotated under the action of the fixed rod, and the tooth plate is moved downward by the action of the second gear, so that the slider 2 moves downward under the action of the telescopic rod and the sliding rod.

[0004] However, the above technical solution still has the following deficiencies in practical application: When glue is dispensed on multiple circuit boards in sequence, the staff needs to frequently remove the circuit boards that have been glued from the clamping assembly, which is rather troublesome. In addition, the glue on the surface of the circuit board just after the glue dispensing work is completed still needs a certain amount of time to solidify. When the staff manually removes the circuit board that has been glued, it is easy to accidentally touch the glue on the surface of the circuit board, thereby affecting the glue dispensing effect. In addition, the manually removed circuit boards may be placed in a relatively messy state around, which is not only not conducive to subsequent unified transportation, but may also affect the glue curing due to contact between the circuit boards. In addition, manually arranging the circuit boards that have been glued is also relatively time-consuming and labor-intensive.

In addition, according to the diameter of the circuit board, the limiting plate one, the limiting plate two, and the limiting plate three can be moved radially to fit with the edge of the circuit board to better limit the circuit board, prevent the circuit board from shifting, and ensure The stability of placement is ensured, and after the glue on the surfaces of multiple circuit boards placed on the support block has solidified, the insertion rod can be used to pass through all the plug holes again, and then the adjustment rod can be driven to move horizontally again to make the support block away from the bottom of the circuit board, and multiple circuit boards fall together, which is convenient for collecting multiple circuit boards on the support block. At the same time, the limiting plate 1, the limiting plate 2, and the limiting plate 3 are driven to move radially to push the fallen circuit boards, so that the axes of multiple circuit boards are aligned, which is easier to transport. Moreover, when a single circuit board needs to be taken out, the limiting plate 1 can be driven to rotate so that the limiting plate 1 no longer fits with the front edge of the circuit board. At this time, the staff can manually move the support block at the corresponding position to remove the circuit board with unsatisfactory glue dispensing effect, and perform glue dispensing again, thereby avoiding the situation where the remaining circuit boards fall off in order to take out one circuit board, thereby affecting the normal placement of the remaining circuit boards.

[0034] Specifically, the existing clamping assembly for printed circuit board processing can fix the circuit board when in use, but when glue is dispensed on multiple circuit boards in sequence, the staff needs to frequently remove the circuit boards that have been glued, which is troublesome. In addition, the glue on the surface of the circuit board just after the glue dispensing work is completed still needs a certain amount of time to solidify. When the staff manually removes the circuit board that has been glued, it is easy to accidentally touch the glue on the surface of the circuit board, thereby affecting the glue dispensing effect. In addition, the manually removed circuit board may be placed in a relatively messy state around, which is not only not conducive to the subsequent unified transportation, but also may affect the glue curing due to the contact between the circuit boards. In addition, manually arranging the circuit boards that have been glued is also relatively time-consuming and labor-intensive. Therefore, in order to solve the above problem, this embodiment is used for a batch of circular circuit boards with the same specifications. When the first circuit board is glued, the motor 5 26 drives the threaded rod 17 to rotate, so that the fixing ring 15 slides and descends on the sliding rod 18, so that the circuit board after glue dispensing can be lowered. In the initial state, one side surface of multiple support blocks 17 is flush with one side surface of the limit plate 3 22, and the insertion rod 13 is inserted into the insertion holes 19 of all support blocks 17; when the lower surface of the circuit board is flush with the upper end surface of the lowest support block 17, the motor 2 15 is started to drive the threaded rod 2 12 to rotate, so that the insertion rod 13 rises a distance, so that the insertion rod 13 is no longer inserted into the insertion hole 19 on the lowest support block 17. At this time, the support block 17 loses the restriction of the insertion rod 13, the spring 18 recovers, and the lowest support block 17 moves to support the bottom of the circuit board. At this time, multiple pressing The rod 6 is away from the circuit board to loosen the circuit board, and then the fixing ring 5 rises to the initial position. At this time, the staff can place the next circuit board to be glued on the pressing rod 6 and press it to fix it, and then repeat the above operation. Every time a circuit board drops, the insertion rod 13 will rise a certain distance and release a supporting block 17 to support the circuit board, thereby realizing the automatic removal of the circuit board after glue dispensing, eliminating the process of frequent manual removal of the circuit board by the staff, which is more labor-saving. At the same time, it also avoids the situation where the glue dispensing effect is affected by the staff accidentally touching the glue on the surface of the circuit board. In addition, since multiple circuits are neatly stacked and will not touch each other, it is not only convenient for the subsequent transportation of the circuit board, but also avoids the situation where the glue on the surface of the circuit board after glue dispensing is touched due to the messy placement of the circuit board around, thereby affecting the glue dispensing effect. Furthermore, according to the diameter of the circuit board, the motor 6 29 can drive the gear 2 30 to rotate, so as to rotate the chute ring 27, and the plurality of guide pillars 2 31 can drive the limiting plate 1 10, the limiting plate 2 11, and the limiting plate 3 22 to move radially, so as to better limit the circuit board, prevent the circuit board from shifting, and ensure the stability of placement; After the glue on the surfaces of the multiple circuit boards placed on the support block 17 is solidified, the motor 4 23 can be used to drive the threaded rod 3 25 to rotate, so that the adjustment rod 16 can be moved laterally, so that the insertion rod 13 is aligned with the insertion holes 19 on the multiple support blocks 17, and the insertion rod 13 is driven to descend until it passes through all the insertion holes 19, and then the adjustment rod 16 is driven to move laterally again to make the support block 17 away from the bottom of the circuit board. At this time, multiple circuit boards fall together, and then the staff can collect the fallen circuit boards uniformly. At the same time, the fallen circuit boards can also be pushed according to the above-mentioned method of driving the limit plate 10, the limit plate 2 11, and the limit plate 3 22 to move radially, so that the axes of the multiple circuit boards are aligned, which is easier to transport; In some cases, when multiple circuit boards are placed on the support block 17 at the same time and waiting for the glue to solidify, the staff can observe the glue dispensing quality on the surface of each circuit board. When it is found that the glue dispensing effect of some circuit boards is not ideal and needs to be dispensed again, if the circuit boards with unsatisfactory glue dispensing effect are removed by causing multiple circuit boards to fall at the same time, it will affect the placement of the remaining circuit boards. Therefore, in order to avoid the above situation, when a single circuit board needs to be taken out, the motor three 21 can be started to drive the limit plate 10 to rotate so that the limit plate 10 no longer fits the front edge of the circuit board. At this time, the staff can manually move the support block 17 at the corresponding position to remove the circuit board with unsatisfactory glue dispensing effect and perform glue dispensing again, thereby avoiding the situation where the remaining circuit boards fall in order to take out one circuit board, thereby affecting the normal placement of the remaining circuit boards.

[0035] Working principle: Place the circular circuit board to be processed within the inner circle of the fixing ring 5, and make the edge of the circuit board fit with the clamping rod 6 on either side, then start the motor 3 to drive the gear 4 to rotate, so that the bevel ring 2 can rotate, and the bevel ring 2 drives multiple guide pillars 9 and the clamping rod 6 to move radially at the same time until all the clamping rods 6 fit with the edge of the circuit board, so that the circuit board can be clamped, so that circular circuit boards with different diameters can be positioned, thereby ensuring the stability of the circuit board during processing. When the first circuit board is glued, the motor 5 26 drives the threaded rod 7 to rotate, so that the fixing ring 5 is The slide bar 18 slides and descends, and the circuit board with glue dispensing completed can be lowered. In the initial state, the one side surface of multiple support blocks 17 is flush with the one side surface of the limit plate 3 22, and the insertion rod 13 is inserted into the insertion holes 19 of all support blocks 17; when the lower surface of the circuit board is flush with the upper end surface of the lowest support block 17, the motor 2 15 is started to drive the threaded rod 2 12 to rotate, so that the insertion rod 13 rises a distance, so that the insertion rod 13 is no longer inserted into the insertion hole 19 on the lowest support block 17. At this time, the support block 17 loses the restriction of the insertion rod 13, the spring 18 recovers, and the lowest support block 17 moves to support the bottom of the circuit board. At this time, the multiple clamping rods 6 can be driven away from the circuit board to loosen the circuit board, and then the fixing ring 5 rises to the initial position. At this time, the staff can place the next circuit board to be glued on the clamping rod 6 and clamp it and fix it, and then repeat the above operation. Every time a circuit board drops, the insertion rod 13 will rise a certain distance and release a support block 17 to support the circuit board, thereby realizing the automatic removal of the circuit board after glue dispensing, eliminating the process of staff frequently manually removing the circuit board, which is more labor-saving. At the same time, it also avoids the glue on the surface of the circuit board accidentally touched by the staff, which may cause The dispensing effect is affected, and since multiple circuits are neatly stacked and do not touch each other, it is not only convenient for the subsequent transportation of the circuit board, but also avoids the situation where the glue on the surface of the circuit board is touched due to the circuit board being placed around in a messy manner, thereby affecting the dispensing effect; and, according to the diameter of the circuit board, the motor 6 29 drives the gear 2 30 to rotate, so as to rotate the inclined groove ring 27, and the plurality of guide pillars 2 31 drive the limit plate 1 10, the limit plate 2 11, and the limit plate 3 22 to move radially, so as to better limit the circuit board, prevent the circuit board from shifting, and ensure the stability of placement;After the glue on the surfaces of the multiple circuit boards placed on the support block 17 is solidified, the motor four 23 can be used to drive the threaded rod three 25 to rotate, so that the adjusting rod 16 can be moved laterally, so that the insertion rod 13 is aligned with the insertion holes 19 on the multiple support blocks 17, and the insertion rod 13 is driven to descend until it passes through all the insertion holes 19, and then the adjusting rod 16 is driven to move laterally again to move the support block 17 away from the bottom of the circuit board. At this time, multiple circuit boards fall together, and then the staff can collect the fallen circuit boards in a unified manner. At the same time, the fallen circuit boards can also be pushed according to the above-mentioned method of driving the limit plate one 10, the limit plate two 11, and the limit plate three 22 to move radially, so that the axes of the multiple circuit boards are aligned, which is easier to transport; in some cases, when multiple circuit boards are placed on the support block 17 at the same time While waiting for the glue to solidify, the staff can observe the glue dispensing quality of each circuit board surface. When it is found that the glue dispensing effect of some circuit boards is not ideal and needs to be dispensed again, if the circuit boards with unsatisfactory glue dispensing effect are removed by causing multiple circuit boards to fall at the same time, it will affect the placement of the remaining circuit boards. Therefore, in order to avoid the above situation, when a single circuit board needs to be removed, the limiting plate 10 can be driven to rotate by starting the motor 3 21 so that the limiting plate 10 is no longer in contact with the front edge of the circuit board. At this time, the staff can manually move the support block 17 at the corresponding position to remove the circuit board with unsatisfactory glue dispensing effect and perform glue dispensing again, thereby avoiding the situation where the remaining circuit boards fall in order to remove one circuit board, thereby affecting the normal placement of the remaining circuit boards. ;
