[0002] Circuit board conveying equipment is an indispensable key piece of equipment in the modern electronics manufacturing industry. It is mainly used to efficiently and stably transfer circuit boards in SMT, 3C automation and other production processes. The equipment is usually composed of a drive unit, conveyor belt, control unit and auxiliary components. Its core components include a double-sided narrow belt or chain conveyor belt, which can accurately transfer circuit boards at an adjustable speed.

[0003] The prior art discloses a conveying device for circuit board processing, including a conveying table and an adjusting mechanism. The conveying table has connecting frames fixedly connected to its upper left and right sides. Each connecting frame has a guide groove at its upper end. A U-shaped frame symmetrically arranged front and rear is slidably connected between the upper ends of the two guide grooves. Conveyor rollers are rotatably connected to the left and right ends of the U-shaped frames. Two adjacent conveyor rollers are connected via a conveyor belt. Evenly distributed support rollers are rotatably connected to the inside of the U-shaped frames, located between two conveyor rollers. The outer arc surface of each support roller contacts the inner surface of the adjacent conveyor belt. This conveying device for circuit board processing allows for flexible and rapid movement of the conveying equipment closer to and further away from the circuit boards via the adjusting mechanism, meeting the processing and conveying needs of circuit boards of different sizes.

[0004] The aforementioned device cannot flip the circuit board during the transportation process.

[0005] Therefore, it is necessary to provide a flipping device for circuit board conveying equipment to solve the above-mentioned technical problems. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a flipping device for circuit board conveying equipment that can realize the flipping of circuit boards.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0025] In the process of circuit board processing, flipping is essential. First, flipping ensures consistent processing precision on both sides of the circuit board. Since both sides of the circuit board require precision operations such as wiring and drilling, failing to flip it promptly after processing only one side may lead to deviations on the other side, affecting overall performance. Second, flipping helps improve production efficiency. By rationally arranging the flipping process, the production line can be made smoother, reducing waiting time and thus increasing output speed. In addition, flipping can effectively reduce the defect rate. During processing, timely flipping allows workers to easily inspect both sides of the circuit board. Once defects are found, adjustments and repairs can be made in a timely manner, avoiding quality problems in the final product. The inventors discovered that for small processing plants, the current circuit board processing flipping operation still relies on manual labor, which is relatively inefficient. Combining the flipping operation with the circuit board conveying operation will help improve the production efficiency of circuit boards.

[0026] First embodiment:

[0027] like Figure 1-3 As shown, the flipping device of the circuit board conveying equipment provided by this utility model includes: a frame 10, which is the load-bearing component of the device, and its shape is as follows. Figure 1 As shown in the figure, and a flipping frame 20 mounted on the frame 10 for flipping the circuit board;

[0028] Specifically, such as Figure 1As shown, the frame 10 includes two parallel crossbeams 11 of the same specifications. The crossbeams 11 can be welded to other adjacent equipment to fix their positions. Each of the two ends of the crossbeam 11 is welded with a support leg 12, or a connecting rod is welded between the support legs 12 to form a closed frame structure. At the same time, a roller 15 is rotatably mounted on the inner sidewall of each end of the crossbeam 11. A transmission belt 14 is fitted on the two rollers 15. The transmission belt 14 is made of rubber material and has a certain width. The top of the belt is used to place the circuit board and support its movement. The transmission belt 14 is driven by the rollers 15, which are driven by a drive assembly (not shown in the figure). The drive assembly is a relatively mature technology (refer to CN221458892U and other documents), which will not be described in detail here. In this way, the circuit board can move from one end of the crossbeam 11 to the other end as the transmission belt 14 rotates.

[0029] The core component of the flipping frame 20 is the turntable 21, which is rotatably mounted on the crossbeam 11. The shape of the turntable 21 is as follows: Figure 2 As shown, the turntable 21 is circular and consists of eight identical arc-shaped pieces 211. The pieces are not continuous; instead, they have gaps (slots 212) for inserting circuit boards. The turntable 21 is driven by a motor 22. Figure 1 In this assembly, the motor 22 and the turntable 21 are symmetrically mounted on two crossbeams 11. Simultaneously, when the two turntables 21 rotate, the slots 212 on them correspond to each other, and the rotation of the two turntables 21 is synchronized. For example, with... Figure 3 As shown in the diagram, the turntable 21 stops rotating when the slot 212 near the circuit board is in a horizontal position. Then, the circuit board moves on the conveyor belt 14 and is transported to the slots 212 of the left and right turntables 21. The turntable 21 rotates. When the turntable 21 rotates 180°, the circuit board is flipped over and placed on the conveyor belt 14 again. At this time, the turntable 21 stops rotating. When the circuit board is disengaged from the slot 212 by the drive of the conveyor belt 14, the turntable 21 starts again. During this process, the start and stop of the conveyor belt 14 are coordinated with the start and stop of the turntable 21.

[0030] The circuit board can be automatically flipped during transmission by setting up the flipping frame 20.

[0031] Second embodiment:

[0032] To further improve the applicability of the device, an adjustment component 30 is added to the device to adjust the distance between the two crossbeams 11, thereby adjusting the distance on the transmission belt 14 installed on the crossbeams 11, so as to be suitable for the transmission and flipping of circuit boards of various specifications.

[0033] Specifically, the adjusting member 30 includes a side plate 31, the shape of which is as follows: Figure 2As shown, two horizontally oriented strip brackets 32 are welded and fixed to the lower end of the side plate 31. The brackets 32 are perpendicular to the side plate 31 and are L-shaped in general. A sliding rod 33 and a threaded rod 34 are arranged between the two crossbeams 11. The sliding rod 33 is fixedly connected to one crossbeam 11 on which the side plate 31 is installed and slides through a pre-set through hole on the other crossbeam 11. One end of the threaded rod 34 is rotatably connected to one crossbeam 11 on which the side plate 31 is installed, and the other end is threaded through a pre-set threaded hole on the crossbeam 11 that matches it. A limiting block 322 that restricts excessive displacement of the crossbeam 11 is also welded and fixed to the end of the threaded rod, and the other end is welded to it. The upper part is a handwheel 341 for driving rotation. On the other hand, each bracket 32 ​​is fixed with a slide rail 321 parallel to its axis by bolts or other means. The bottom of a crossbeam 11 without side plate 31 is provided with a slide groove that matches the slide rail 321. The slide groove fits into the slide rail 321. The principle of this part of the structure is a screw mechanism. That is, by rotating the handwheel 341, the screw rod 34 is driven to rotate. The screw rod 34 pushes the crossbeam 11 without side plate 31 to slide on the slide rail 321. It should be noted that in this embodiment, the device should first be raised by a forklift or other device until the outrigger 12 is off the ground, and then adjusted. After the adjustment is completed, the device is placed on the ground.

[0034] The distance between the two transmission belts 14 can be adjusted by setting the adjustment component 30, thus making it suitable for circuit boards of various specifications.

[0035] Third embodiment:

[0036] To ensure stable operation of the device, foot pads 13 are provided at the lower end of the outriggers 12, such as... Figure 1 As shown, the foot pad 13 consists of a truncated cone made of rubber and a lead screw fixedly mounted on the truncated cone. The lower end of the support leg 12 has a threaded hole for the lead screw to be screwed in. On uneven ground, the exposed length of the lead screw can be adjusted by rotating the foot pad 13, thereby compensating for the depressions or protrusions of the ground and keeping the upper end of the device level.

[0037] In use, first place the circuit board on the transmission belt 14, then turn on the motor 22 to drive the turntable 21 to rotate. As the circuit board enters the slot 212 of the turntable 21 under the transmission of the transmission belt 14, the rotating turntable 21 flips the circuit board 180° and puts it back on the transmission belt 14.

[0038] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
