Description

[0002] In the automated production process of circuit boards, the silo temporary storage mechanism is a key node for loading or unloading circuit boards, and plays a connecting role. Currently, common silo temporary storage mechanisms usually include a robotic arm and multiple temporary storage silos set on the same plane. The robotic arm grabs the circuit boards, identifies them, and places them in the corresponding temporary storage silos to store circuit boards of different lot numbers or first boards. However, this design of multiple silos set on the same plane, because the robotic arm puts / takes the boards up and down, causes multiple silos to occupy too much area, greatly increasing the volume of the silo temporary storage mechanism and reducing the space utilization rate of automated production.

[0012] In order to better understand the purpose, structure and function of the present invention, the specific embodiment of the present invention "a circuit board multi-layer silo temporary storage mechanism" is further described in detail below with reference to the accompanying drawings.

[0013] See also Figure 1-Figure 3In this embodiment, the multi-layer silo temporary storage mechanism includes a fixed frame 100, on which a robotic arm 101 and a first platform 102 are fixedly arranged. The first platform 102 is located in front of and below the robotic arm 101; the fixed frame 100 is also provided with a plurality of second platforms 103 that are parallel to the first platform 102 and are stacked up and down. The second platforms 103 can be slid forward and backward on the fixed frame 100, and a plurality of driving components 104 are also fixedly arranged on the fixed frame 100. The driving components 104 are connected to the second platforms 103 in a one-to-one correspondence. When working, after the robotic arm 101 grabs the circuit board for identification, if the circuit board needs to be placed on the first platform 102, the robot arm 101 directly places it on the first platform 102 from top to bottom. If the circuit board needs to be placed on a second platform 103, the corresponding second platform 103 will slide forward to the top of the first platform 102 under the drive of the drive component 104. The robot arm 101 still places the circuit board on the corresponding second platform 103 from top to bottom according to the previous path. After the circuit board is placed, the drive component 104 drives the second platform 103 to slide back to the waiting area. The waiting area has multiple second platforms 103 set in upper and lower positions and parallel to each other. The other second platforms can repeat the above steps to realize multi-layer storage operations. The multi-layer silo temporary storage mechanism of the present invention can achieve the effect of temporarily storing circuit boards on three or more platforms with an area of ​​at most two platforms, which greatly reduces the volume of the mechanism, improves the space utilization rate of the mechanism, and improves the space utilization rate of automated production.

[0014] It should be noted that the robot arm 101 and the drive assembly 104 in this embodiment are electrically connected to the central controller, which is a central industrial control device in the prior art, and the recognition of the circuit board is achieved through the recognition function of the robot arm 101 in the prior art or another scanning camera electrically connected to the central controller, so as to achieve automatic recognition and automatic operation of the entire mechanism; and the drive assembly 104 in this embodiment can be a drive mechanism such as a cylinder or motor in the prior art, without limiting its specific category, as long as it can receive commands from the central controller to drive the second platform 103 to slide back and forth into place.

[0015] More specifically, in this embodiment, the waiting area is located directly below the robotic arm 101, so that the waiting area does not need to occupy an additional platform area. In this way, the mechanism only needs the area of ​​one platform to achieve the effect of temporarily storing circuit boards on three or more platforms, further improving the space utilization of the mechanism.

[0016] See further Figure 2 and Figure 3In this embodiment, a plurality of slide rails 105 are provided on the fixed frame 100 in parallel with each other in upper and lower positions. The slide rails 105 extend from both sides directly above the first platform 102 to both sides of the waiting area. The second platform 103 is slidably set on the fixed frame 100 through the slide rails 105, so that the second platform 103 can slide smoothly between directly above the first platform 102 and the waiting area.

[0017] See further Figure 3 In this embodiment, the fixed frame 100 is also provided with an in-position sensor 108 electrically connected to the central controller, and the second platform 103 is provided with an in-position part 109. The in-position sensor 108 is located on the moving path of the in-position part 109 to feedback the position signal of the forward and backward movement of the second platform 103 to the central controller, ensuring that the second platform 103 accurately moves forward to directly above the first platform 102 or moves backward to the waiting area.

[0018] More specifically, in this embodiment, a laser displacement sensor (not shown) is provided on the fixing frame 100. The laser displacement sensor projects light from top to bottom and can feed back the height signal of the first platform 102 / second platform 103 to the central controller. The central controller then controls the height to which the robotic arm 101 descends to ensure that the robotic arm 101 accurately places the circuit board on a platform at a corresponding height.

[0019] See further Figure 3 In this embodiment, vertical limit plates 106 are provided on the first platform 102 and the second platform 103, and a guide slope 107 is provided on the top of the limit plate 106. When the robotic arm 101 places the circuit board downward, the edge of the circuit board will fall into the limit area of ​​the limit plate 106 along the guide slope 107, ensuring that the circuit board can accurately fall into the limited area of ​​the first platform 102 and the second platform 103, preventing the circuit board from deviating on the platform.
