Description

Technical Field

[0001] This utility model relates to the field of circuit board tooling technology, specifically to a batch mounting device for mobile phone integrated circuit boards. Background Technology

[0002] The mobile phone integrated circuit board is the core hardware carrier of the mobile phone, integrating key components such as processor, baseband chip, power management module, radio frequency transceiver, sensor interface and memory chip. It achieves high-speed signal transmission and low power consumption through multi-layer printed circuit and micron-level wiring technology.

[0003] When using an automatic pick-and-place machine, integrated circuit boards are typically fixed to a tray and fed into the placement process along a track. During movement, the tray can easily deviate from its identification position due to track guidance or forced movement, leading to placement defects such as misalignment. After such defects occur, each board must be manually returned to the tray, a cumbersome operation with low accuracy, and common placement problems are still prone to occur. Therefore, a batch placement device for mobile phone integrated circuit boards is needed to meet these needs. Utility Model Content

[0004] The purpose of this invention is to provide a batch surface mount device for mobile phone integrated circuit boards to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a batch placement device for mobile phone integrated circuit boards, comprising: a placement table, a material tray conveyor belt on the placement table, a material tray drop plate fixedly installed on one side of the placement table, multiple material trays stacked on the material tray drop plate, and a material tray drop mechanism and a buffer mechanism provided on the material tray drop plate;

[0006] Preferably, the tray dropping mechanism includes a vertical rail, which is fixedly installed on both sides of the top of the tray dropping plate. Movable brackets are slidably installed on both sides of the patching table and the tray dropping plate.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a batch placement device for mobile phone integrated circuit boards, including: a placement table 1, a material tray conveyor belt 101 on the placement table 1, a material tray drop plate 2 fixedly installed on one side of the placement table 1, multiple material trays 3 stacked on the material tray drop plate 2, a material tray drop mechanism 4 and a buffer mechanism 5 on the material tray drop plate 2, after the integrated circuit board is fixed on the material tray 3, the material tray 3 is moved down in sequence by the material tray drop mechanism 4, and then sent to the placer for placement under the action of the material tray conveyor belt 101;

[0023] To ensure that the material trays 3 enter the material tray conveyor belt 101 in an orderly manner, the material tray falling mechanism 4 includes a vertical rail 401, which is fixedly installed on both sides of the top of the material tray falling plate 2. Lateral sliding shafts 301 are installed on both sides of the material trays 3, and the lateral sliding shafts 301 are slidably installed in the vertical rail 401. Vertical limiting posts 302 are installed on the material trays 3. The material trays 3 are stacked in sequence, and the top of the vertical limiting post 302 contacts the bottom of the upper material tray 3. Sliding shaft tracks 402 are opened on both sides of the mounting table 1. The vertical rail 401 on the same side is connected to the sliding shaft track 402. The lateral sliding shafts 301 on the material trays 3 are all located in the vertical rail 401 and can slide from the vertical rail 401 into the sliding shaft track 402.

[0024] To ensure the trays 3 fall sequentially, movable brackets 403 are slidably installed on both sides of the placement table 1 and the tray drop plate 2. Conveyor belt positioning rods 404 and drop positioning rods 405 are fixedly installed on the movable brackets 403. The conveyor belt positioning rods 404 are located above the tray conveyor belt 101. When the tray 3 is moved by the tray conveyor belt 101 to below the placement unit, the conveyor belt positioning rods 404 contact the vertical limit post 302 and fix the tray 3, so that the placement can be accurately matched and misalignment is avoided. The drop positioning rods 405 are located above the tray drop plate 2. When a tray 3 falls onto the tray drop plate 2, the drop positioning rods 405 hold the bottom of the upper tray 3, so that the trays 3 on the vertical rail 401 fall periodically. A toothed plate 406 is fixedly installed at the bottom of the movable support 403, and a reciprocating motor 407 is fixedly installed at the bottom of the tray drop plate 2. A toothed disc 408 is fixedly installed at the output end of the reciprocating motor 407. The two toothed plates 406 are located on both sides of the toothed disc 408. The toothed plates 406 are provided with teeth. The toothed disc 408 meshes with the teeth of the toothed plates 406 on both sides. The reciprocating motor 407 drives the movable support 403 on both sides to perform periodic reciprocating motion. When the movable support 403 moves away from the placement table 1, the conveyor belt positioning rod 404 on the movable support 403 separates from the vertical limiting post 302 of the tray 3 on the tray conveyor belt 101, so that the tray 3 that has completed the placement operation is transferred by the tray conveyor belt 101. At the same time, the drop positioning rod 405 on the movable support 403 separates from the bottom of the tray 3, so that the tray 3 can move down onto the tray drop plate 2.

[0025] When the movable support 403 reciprocates, in addition to being fixed by the collar at the bottom of the material tray drop plate 2, a support limiting rod 409 is also fixedly installed on the movable support 403. Support limiting grooves 410 are opened on both sides of the material tray drop plate 2. The support limiting rod 409 is slidably installed in the support limiting groove 410. The support limiting rod 409 and the support limiting groove 410 assist in limiting the movement and prevent the movable support 403 from shifting.

[0026] Example 2: As Figure 3 When the tray 3 falls, a buffer mechanism 5 is provided on the tray falling plate 2 to buffer the tray 3. The buffer mechanism 5 includes a buffer plate 501. A buffer plate movable groove 502 is provided on the tray falling plate 2. The buffer plate 501 is slidably installed in the buffer plate movable groove 502. A vertical limiting shaft 503 is fixedly installed in the buffer plate movable groove 502. The buffer plate 501 is slidably installed on the vertical limiting shaft 503. A buffer spring 504 is sleeved on the vertical limiting shaft 503. The bottom of the buffer plate 501 is in contact with the top of the buffer spring 504. When the falling positioning rod 405 on the movable bracket 403 separates from the tray 3, the tray 3 falls. The tray 3 is buffered by the buffer plate 501 and the buffer spring 504. The remaining features are the same as in Embodiment 1.

[0027] The working principle is as follows: During operation, the mobile phone integrated circuit board to be mounted is fixed on the tray 3. The output end of the reciprocating motor 407 drives the gear plate 408 to rotate. Under the meshing action of the gear plates 406 on both sides, the movable brackets 403 on both sides reciprocate. When the movable brackets 403 move away from the mounting table 1 and the tray drop plate 2, the falling positioning rod 405 on the movable bracket 403 separates from the bottom of the tray 3, causing the tray 3 to fall. The lateral sliding shaft 301 on the tray 3 enters the sliding shaft track 402 from the vertical rail 401, and is then transported to the bottom of the mounter by the tray conveyor belt 101. After a tray 3 falls onto the tray drop plate 2, the movable bracket 403 returns to its original position. Initially, the bottom of the upper tray 3 is held in place by the falling positioning rod 405, causing the tray 3 on the vertical rail 401 to fall periodically. At this time, the conveyor belt positioning rod 404 on the movable bracket 403 returns to the top of the tray conveyor belt 101, and the tray 3 on the tray conveyor belt 101 reaches the bottom of the placeer and is limited by the conveyor belt positioning rod 404. After the tray 3 on the tray conveyor belt 101 completes the placement operation, the movable bracket 403 moves away from the placement table 1 and the tray drop plate 2 again. At this time, the conveyor belt positioning rod 404 on the movable bracket 403 separates from the vertical limiting post 302 on the tray 3, and the tray 3 after being released from the limit is transferred by the tray conveyor belt 101.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
