Description

Technical Field

[0001] The utility model belongs to the technical field of circuit board processing, and particularly relates to a self-balancing upper and lower board storage machine. Background Art

[0002] In the electronics manufacturing industry, the production and assembly of circuit boards is a complex and delicate process. Before mounting electronic components, the circuit boards need to be accurately and stably placed on a conveyor belt for further processing and assembly. Traditionally, this process relies on manual operation, where workers need to manually place the circuit boards on a conveyor belt. However, this method is not only labor-intensive and increases labor costs, but it is also difficult to ensure the accuracy and stability of circuit board placement.

[0003] In order to solve the above problems, automated loading and unloading board storage machines came into being. These machines can automatically load, unload and store circuit boards, significantly improving production efficiency and reducing labor costs. However, traditional loading and unloading board storage machines often rely on manual operation during the board storage process, resulting in the stored circuit boards being in an unbalanced state. When these unbalanced circuit boards are unloaded to the board feeding mechanism, they may become stuck, or make abnormal noises or even damage the circuit boards due to misalignment when being pushed out of the card slots. In addition, in the case where some circuit boards have already been mounted with electronic components, the protruding parts of the electronic components may trigger the unloading sensor in advance during the unloading process, causing the sensor to misjudge, thereby affecting the accuracy and stability of the unloading.

[0004] Therefore, there is an urgent need for a self-balancing upper and lower board storage machine that can automatically balance the circuit board during the board unloading process. Utility Model Content

[0005] The purpose of the utility model is to provide a self-balancing upper and lower board storage machine to address the deficiencies in the prior art, which can automatically balance the circuit board during the board unloading process, ensure the accurate alignment and smooth transmission of the circuit board and the board feeding mechanism, and improve production efficiency and product quality.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0031] See attached Figure 1 To Attachment Figure 4 , the figure shows a specific embodiment of a self-balancing upper and lower board storage machine provided by the utility model.

[0032] See attached Figure 1 , the self-balancing upper and lower board storage machine includes:

[0033] The upper and lower plate mechanism 1 comprises a first vertical track 110 and a second vertical track 120 which are arranged opposite to each other and spaced apart from each other. The first vertical track 110 and the second vertical track 120 are both provided with a plurality of slots 130 for holding circuit boards, and a motor 140 for driving the slots 130 to move in a longitudinal cycle.

[0034] The board delivery mechanism 2 includes a first horizontal track 210 disposed near the inner side of the first vertical track 110 and a second horizontal track 220 disposed near the inner side of the second vertical track 120. The first horizontal track 210 and the second horizontal track 220 are both provided with a lower board sensing mechanism 3 for sensing the lower board to the circuit board near the board delivery mechanism 2.

[0035] The grating sensing mechanism 4 disposed on the first vertical track 110 and the second vertical track 120 is used to sense the alignment state of the card slot 130 and the plate feeding mechanism 2 .

[0036] See attached Figure 2 In the above embodiment, the motor 140 of the first vertical track 110 drives the card slot 130 to move in a circular motion on the first vertical track 110, and the motor of the second vertical track 120 drives the card slot 130 to move in a circular motion on the second vertical track 120. The card slot 130 of the first vertical track 110 and the card slot 130 of the second vertical track 120 are arranged opposite to each other to hold the circuit board. Assuming that when storing the board, the lower end surface of a circuit board has been mounted with electronic components, and the end of the circuit board held on the first vertical track 110 is lower than the end of the second vertical track 120, that is, the circuit board is tilted from the end of the second vertical track 120 to the end of the first vertical track 110, then the process of lowering the board is as follows: the motors 140 of the first vertical track 110 and the second vertical track 120 drive the card slot 130 to move downward, and the circuit board held on the card slot 130 moves downward, and the circuit board first contacts the lower board sensing mechanism 3 on the first horizontal track 210, indicating that the circuit board is close to the first horizontal track 210 but has not yet been aligned. The slot 130 of the first vertical track 110 continues to move downward until the sensing slot 130 of the grating sensing mechanism 4 is aligned with the first horizontal track 210, and the motor 140 on the first vertical track 110 stops working; the motor 140 of the second vertical track 120 continues to work and executes the same process as the first vertical track 110 until the sensing slot 130 of the grating sensing mechanism 4 on the second vertical track 120 is aligned with the second horizontal track 220, and the motor 140 on the second vertical track 120 stops working, thereby ensuring that the circuit board can be accurately aligned when the board is lowered, avoiding the problem of circuit board misalignment or jamming.

[0037] See attached Figure 2In the above embodiment, when a slot 130 on the first vertical track 110 is aligned with the first horizontal track 210 in height, the grating sensing mechanism 4 on the first vertical track 110 will be triggered; when a slot 130 on the second vertical track 120 is aligned with the second horizontal track 220 in height, the grating sensing mechanism 4 on the second vertical track 120 will be triggered. The grating sensing mechanism 4 includes a grating disk 410 connected to the motor 140 in transmission, and a grating sensor 420 arranged near the grating disk 410, and a plurality of grating holes 411 are arranged around the grating disk 410. In the embodiment, the grating holes 411 on the grating disk 410 are designed such that when the slot 130 of the first vertical track 110 is aligned with the first horizontal track 210 in height, the grating sensor 420 on the first vertical track 110 triggers a sensing signal through the grating holes 411; when the slot 130 aligned with the first horizontal track 210 in height switches to the next slot 130, the grating disk 410 on the first vertical track 110 rotates to the grating sensor 420 corresponding to the next grating hole 411. The working principle of the second vertical track 120 is the same as that of the first vertical track 110. Optionally, the grating disk 410 can be designed such that the arc length between two adjacent grating holes 411 on the grating disk 410 is equal to the width between two upper and lower adjacent slots 130 of the upper and lower plate mechanism 1.

[0038] See attached Figure 3 In the above embodiment, the grating sensor 420 includes a transmitter head 421 and a receiver head 422, and the transmitter head 421 and the receiver head 422 are respectively located on both sides of the grating disk 410; when the sensing signal of the transmitter head 421 passes through the grating hole 411 and is received by the receiver head 422, the card slot 130 is aligned with the plate feeding mechanism 2 in height. In the embodiment, by judging the timing when the sensing signal of the transmitter head 421 passes through the grating hole 411 and is received by the receiver head 422, it can be known whether there is a card slot 130 aligned with the first horizontal track 210 or the second horizontal track 220, so as to facilitate the control of the motor 140 to stop working in time.

[0039] See attached Figure 3 In the above embodiment, a sprocket 150 is provided on the first vertical track 110 and the second vertical track 120, and the motor 140 is connected to the sprocket 150 through a chain 160 to drive the card slot 130 to move in a longitudinal cycle. This embodiment realizes the continuous and smooth movement of the card slot 130, and improves the operating efficiency and stability of the equipment. Among them, the grating disk 410 is fixed on the sprocket 150 and is coaxial with the sprocket 150. In the embodiment, by fixing the grating disk 410 on the sprocket 150 and being coaxial with the sprocket 150, the movement of the grating disk 410 and the card slot 130 is synchronized, thereby ensuring that the grating sensing mechanism 4 accurately senses and locates the position of the card slot 130.

[0040] See attached Figure 4 In the above embodiment, the lower plate sensing mechanism 3 includes a movable part 310 and a lower plate sensor 320 arranged near the movable part 310. When the circuit board is lowered from the upper and lower plate mechanism 1 to near the plate feeding mechanism 2, the circuit board will contact the movable part 310 to trigger the lower plate sensor 320. The movable part 310 is provided with a rotating end 311, and the two ends of the rotating end 311 are respectively provided with a sinking movable rod 312 and a counterweight plate 313, and the lower plate sensor 320 is arranged near the counterweight plate 313. In the embodiment, the lower plate sensor 320 can accurately sense the lower plate movement of the circuit board, ensure that the circuit board is in place before subsequent operations, and improve the intelligence and automation level of the equipment. Specifically, in the default state, the counterweight plate 313 presses down the sinking movable rod 312 to lift it, and the counterweight plate 313 blocks the lower plate sensor 320, and the lower plate sensor 320 is in an untriggered state. When the lower plate of the circuit board contacts the sinking movable rod 312, the sinking movable rod 312 is pressed down and the weight plate 313 is lifted up, contacting the shielding state of the lower plate sensor 320, and the lower plate sensor 320 is triggered.

[0041] See attached Figure 1 In the above embodiment, a machine frame 5 is further included, and the upper and lower plate mechanisms 1, the plate feeding mechanism 2, and the grating sensing mechanism 4 are all arranged in the machine frame 5; wherein the second vertical track 120 is relatively fixed to the machine frame 5, and the first vertical track 110 can be close to or away from the second vertical track 120. In the embodiment, the first vertical track 110 can be close to or away from the second vertical track 120 to adjust the distance between the card slot 130 of the first vertical track 110 and the card slot 130 of the second vertical track 120 to adapt to circuit boards of different sizes and shapes.

[0042] See attached Figure 1 In the above embodiment, the second horizontal track 220 is relatively fixed to the second vertical track 120, the first horizontal track 210 is relatively fixed to the first vertical track 110 and moves in the machine frame 5 following the first vertical track 110; a screw rod 510 is provided at the top of the machine frame 5, and the first vertical track 110 is connected to the screw rod 510. In the embodiment, the screw rod 510 is transversely arranged at the top of the machine frame 5 and spans the first vertical track 110 and the second vertical track 120. When the screw rod 510 rotates, the first vertical track 110 connected to the screw rod 510 moves along the length direction of the screw rod 510, thereby approaching or moving away from the second vertical track 120, and changing the circuit boards of different sizes and shapes to which it is applicable.

[0043] In summary, the present embodiment provides a self-balancing upper and lower board storage machine, which can accurately sense the alignment state of the card slot 130 and the board feeding mechanism 2 by setting a lower board sensing mechanism 3 to sense the lower board to the circuit board close to the board feeding mechanism 2, and setting a grating sensing mechanism 4 on the upper and lower board mechanism 1, thereby ensuring that the circuit board can be accurately aligned when the board is lowered, avoiding the problem of misalignment or jamming of the circuit board, and improving the stability and reliability of the production process; by setting a grating disk 410 and a grating sensor 420, the grating holes 411 arranged around the grating disk 410 are used to achieve accurate sensing and positioning of the position of the card slot 130, thereby improving the alignment accuracy; by setting a movable part 310 and a lower board sensor 320 to accurately sense the lowering action of the circuit board, it is ensured that subsequent operations are performed after the circuit board is in place, thereby improving the intelligence and automation level of the equipment; the present embodiment can realize automatic balance adjustment of the circuit board during the lowering process, ensuring accurate alignment and smooth transmission of the circuit board and the board feeding mechanism 2, thereby improving production efficiency and product quality.
