Description

Technical Field

[0001] The utility model belongs to the technical field of flexible circuit board patches, and in particular relates to a multifunctional patch fixture for a flexible circuit board. Background Art

[0002] Flexible circuit board patch is the process of installing electronic components on a flexible circuit board. In this process, surface mount technology is usually used to accurately fix various electronic components such as resistors, capacitors, integrated circuits, etc. on specific positions of the flexible circuit board through steps such as solder paste printing, component mounting, and reflow soldering.

[0003] For example, a Chinese patent with publication number CN217563861 U discloses a flexible circuit board patch clamp, which relates to the field of flexible circuit board processing, including a base plate, a fixing seat, a mounting seat, a pulling component and an auxiliary patch component, wherein the four corners of the base plate are fixedly provided with fixing seats, and the two sides of the top of the base plate are symmetrically provided with mounting seats, the mounting seats are slidably connected to the fixing seats, and the fixing seats are also provided with a pulling component for pulling the mounting seats upward, and the two groups of the mounting seats are rotatably installed with a first threaded guide rod and a second threaded guide rod respectively; the utility model places the flexible circuit board on the base plate, lowers the mounting seat by the pulling component, and then drives the first threaded guide rod and the second threaded guide rod to rotate by the driving component, thereby driving the two groups of flattening blocks to move in opposite directions, thereby flattening the flexible circuit board on the base plate and fixing its two ends, thereby solving the problem that traditional clamps cannot remove wrinkles.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when this device removes wrinkles from the flexible circuit board, the flattening block scrapes the wrinkles on the flexible circuit board, which is easy to damage the flexible circuit board, thereby affecting the quality of the flexible circuit board. In addition, before the flexible circuit board is mounted, when there is floating dust on the top of the flexible circuit board, the effect of subsequent mounting of the flexible circuit board will be reduced. In view of this, we propose a multifunctional mounting fixture for flexible circuit boards. Utility Model Content

[0006] The purpose of the utility model is to provide a multifunctional patch fixture for a flexible circuit board to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a multifunctional patch fixture for a flexible circuit board, comprising:

[0008] A base, a rubber pad 1 is fixedly installed on the top of the base, a sliding groove is opened on one side of the base, a sliding plate is slidably installed in the sliding groove, a rubber pad 2 in contact with the top of the rubber pad 1 is fixedly installed on the sliding plate, a spring 1 is symmetrically fixedly installed on the sliding plate and located in the sliding groove, a moving groove is opened on the rear side of the base, and a moving block is slidably installed in the moving groove;

[0009] A power assembly, the power assembly is located in the base and is used to drive the moving block to move;

[0010] A slide groove, the slide groove is opened on one side of the moving block and is located above the rubber pad 1, a mounting rod is slidably installed in the slide groove, a cleaning roller is sleeved on the mounting rod, a threaded rod 1 is rotatably installed in the slide groove, and the top end of the threaded rod 1 passes through the mounting rod and the top of the slide groove and extends to the outside;

[0011] A fixing assembly is located inside the mounting rod and is used to fix the cleaning roller.

[0012] In the present technical solution, by means of the sliding plate provided, the sliding plate is pulled upward, the sliding plate will move upward in the sliding groove and squeeze the two springs 1 to contract, and at the same time, the upward movement of the sliding plate will drive the rubber pad 2 to move upward. When the rubber pad 2 is away from the rubber pad 1, the personnel can pass one end of the flexible circuit board through the bottom of the cleaning roller and place it between the rubber pad 2 and the rubber pad 1. At this time, the sliding plate can be released and pulled, and under the action of the rebound force of the two springs 1, the two springs 1 will squeeze the sliding plate, so that the sliding plate moves downward in the sliding groove, and at the same time, the sliding plate will drive the rubber pad 2 to move downward until the rubber pad 2 squeezes one end of the flexible circuit board onto the rubber pad 1, and then the personnel can rotate the threaded rod 1. When the threaded rod is used, the rotation of the threaded rod will drive the mounting rod to move downward, and the downward movement of the mounting rod will drive the cleaning roller to move downward until the sponge pad on the side of the cleaning roller is against the top of the flexible circuit board. At this time, the sponge pad on the side of the cleaning roller will be slightly deformed, and then the power assembly is driven by the power assembly, and the power assembly drives the moving block to move in the moving groove, and the moving block drives the mounting rod and the cleaning roller to move. The movement of the sponge pad on the side of the cleaning roller can remove the wrinkles of the flexible circuit board and wipe off the floating dust on the top, ensuring that the floating dust on the flexible circuit board can be wiped off before the flexible circuit board is mounted. At the same time, due to the soft texture of the sponge pad, the flexible circuit board will not be damaged during movement.

[0013] Through the setting of the fixing assembly, the fixing assembly can release the cleaning roller, and the personnel can pull the cleaning roller out from the mounting rod and clean the sponge pad on the side of the cleaning roller. When the sponge pad on the side of the cleaning roller is cleaned, the cleaning roller is put on the mounting rod. When the cleaning roller is completely put on the mounting rod, the fixing assembly can fix the cleaning roller to ensure that when the sponge pad on the cleaning roller is stuck with dust, the sponge pad on the cleaning roller can be removed and cleaned in time.

[0014] In the above technical solution, further, the power assembly includes:

[0015] A rectangular groove is opened in the base and is located on one side of the movable groove. A servo motor is fixedly installed in the rectangular groove. The output end of the servo motor passes through one side of the rectangular groove and extends into the movable groove and is fixedly installed with a threaded rod 2. One end of the threaded rod 2 passes through the movable block.

[0016] In the present technical solution, the servo motor is started, and the output shaft of the servo motor will drive the second threaded rod to rotate. Under the action of the thread, the rotation of the second threaded rod will drive the moving block to move in the moving groove, and the moving block will drive the mounting rod and the cleaning roller to move. The movement of the sponge pad on the side of the cleaning roller can remove the wrinkles of the flexible circuit board and wipe off the floating dust on the top, ensuring that the floating dust on the flexible circuit board can be wiped off before the flexible circuit board is mounted. At the same time, due to the soft texture of the sponge pad, the flexible circuit board will not be damaged during movement.

[0017] In the above technical solution, further, the output shaft of the servo motor is rotatably connected to the base, the threaded rod 2 is threadably connected to the moving block, and the threaded rod 2 is rotatably connected to the moving groove.

[0018] In this technical solution, it is ensured that the output shaft of the servo motor can rotate normally in the base, that the rotation of the threaded rod 2 can drive the moving block to move, and that the threaded rod 2 can rotate normally in the moving groove.

[0019] In the above technical solution, further, the fixing assembly includes:

[0020] A limiting groove is provided in the mounting rod, a limiting block is slidably installed in the limiting groove, the top end of the limiting block passes through the top of the limiting groove and extends into the cleaning roller, and a second spring is fixedly installed on the limiting block and in the limiting groove.

[0021] In the present technical solution, the limit block is pressed downward, and the limit block moves downward in the limit groove to squeeze the spring 2 to contract. When the top end of the limit block moves out of the cleaning roller, the limit block can release the cleaning roller, and the personnel can pull the cleaning roller out of the mounting rod and clean the sponge pad on the side of the cleaning roller. At this time, under the action of the rebound force of the spring 2, the spring 2 will squeeze the limit block to reset. When the sponge pad on the side of the cleaning roller is cleaned, the limit block is pressed downward again, and the limit block is in the limit groove. The downward movement will squeeze spring 2 to contract. When the top end of the limit block completely enters the limit groove, the cleaning roller that has been cleaned can be put on the mounting rod again. When the cleaning roller is completely put on the mounting rod, under the action of the rebound force of spring 2, spring 2 will squeeze the limit block to move upward. When the top end of the limit block is inserted into the cleaning roller, the limit block can fix the cleaning roller to ensure that when the sponge pad on the cleaning roller is stuck with dust, the sponge pad on the cleaning roller can be removed and cleaned in time.

[0022] In the above technical solution, further, the top end of the limit block is plugged into the cleaning roller, and the bottom end of the second spring is tightly welded to the inner wall of the limit groove.

[0023] In this technical solution, it is ensured that the top end of the limit block can be inserted into the cleaning roller, thereby ensuring the structural stability of the second spring.

[0024] In the above technical solution, further, the threaded rod 1 is threadedly connected to the mounting rod, and the upper end of the threaded rod 1 is rotatably connected to the moving block.

[0027] In this technical solution, the structure of the spring 1 is ensured to be stable, and the mounting rod is ensured to be able to drive the cleaning roller to move.

[0028] The beneficial effects of the utility model are:

[0029] 1. The multifunctional patch fixture for flexible circuit board has a sliding plate which is set. When the sliding plate is pulled upward, the sliding plate will move upward in the sliding groove and squeeze the two springs 1 to contract. At the same time, the upward movement of the sliding plate will drive the rubber pad 2 to move upward. When the rubber pad 2 is away from the rubber pad 1, the personnel can pass one end of the flexible circuit board through the bottom of the cleaning roller and place it between the rubber pad 2 and the rubber pad 1. At this time, the sliding plate can be released and pulled. Under the action of the rebound force of the two springs 1, the two springs 1 will squeeze the sliding plate, so that the sliding plate moves downward in the sliding groove. At the same time, the sliding plate will drive the rubber pad 2 to move downward until the rubber pad 2 squeezes one end of the flexible circuit board onto the rubber pad 1. Then the personnel can rotate the threaded rod 1. Under the action of the thread, the rotation of the threaded rod will drive the mounting rod to move downward, and the downward movement of the mounting rod will drive the cleaning roller to move downward until the sponge pad on the side of the cleaning roller rests on the top of the flexible circuit board. At this time, the sponge pad on the side of the cleaning roller will be slightly deformed, and then the power assembly is driven by the set power assembly. The power assembly drives the moving block to move in the moving groove, and the moving block drives the mounting rod and the cleaning roller to move. The movement of the sponge pad on the side of the cleaning roller can remove the wrinkles of the flexible circuit board and wipe off the floating dust on the top, ensuring that the floating dust on the flexible circuit board can be wiped off before the flexible circuit board is mounted. At the same time, due to the soft texture of the sponge pad, the flexible circuit board will not be damaged during movement.

[0030] 2. The multifunctional patch fixture for the flexible circuit board can release the cleaning roller through the setting of the fixing component, and the personnel can pull the cleaning roller out from the mounting rod and clean the sponge pad on the side of the cleaning roller. After the sponge pad on the side of the cleaning roller is cleaned, the cleaning roller is put on the mounting rod. When the cleaning roller is completely put on the mounting rod, the fixing component can fix the cleaning roller to ensure that when the sponge pad on the cleaning roller is stuck with dust, the sponge pad on the cleaning roller can be removed and cleaned in time.
