DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A translational circuit board suction machine comprises a workbench 1, the top of the workbench 1 is provided with a plurality of material picking parts 3 through a mounting plate 2, and the inner bottom surface thereof is located below the material picking parts 3 and is provided with a conveyor belt 4 and a collecting box 5, the bottom of the material picking parts 3 is detachably connected with a suction cup 7 through a fastener 6, the conveyor belt 4 is driven by a pair of electric rollers to transport circuit boards, and the collecting box 5 is used to collect and accommodate circuit boards for unified packaging and transportation.

[0023] A driving assembly 8 for driving the material picking member 3 to move is disposed on the top of the workbench 1 . The driving assembly 8 also includes an adjusting assembly 9 . The adjusting assembly 9 is used to adjust the height of the material picking member 3 .

[0024] Furthermore, the material picking component 3 includes a mounting tube 31 fixedly connected to the mounting plate 2, one end of the mounting tube 31 is connected to a mounting block 33 via a telescopic rod 32, the other end of the mounting block 33 is provided with the suction cup 7, the outer sleeve of the telescopic rod 32 is provided with a spring 34, and the two ends of the spring 34 are respectively fixedly connected to the sides of the mounting tube 31 and the mounting block 33.

[0025] It is worth mentioning that the other end of the mounting tube 31 is connected to a connector, which is connected to the air circuit of an external air compressor through the connector to cooperate with the suction cup 7 to suck the circuit board. In addition, the mounting tube 31 and the telescopic rod 32 are both provided with air cavities inside, and they are communicated with the suction cup 7. Through the action of the telescopic rod 32 and the spring 34, it is possible to prevent the suction cup 7 from squeezing and adsorbing the circuit board due to excessive resistance force, thereby preventing the circuit board from being damaged. Moreover, under the action of the spring 34, the telescopic rod 32 can return to its original position and continue to support the suction cup 7 after being squeezed.

[0026] Furthermore, the fastener 6 includes a protrusion 61 and a claw 62 , and a pair of the protrusions 61 are staggered and fixedly installed on both sides of the mounting block 33 and the suction cup 7 at one end facing each other, and the claws 62 are staggered and fixedly installed next to the protrusions 61 .

[0027] It should be noted here that sealing gaskets are provided on the end faces of the mounting block 33 and the suction cup 7 facing each other, and the specific mounting method of the protrusion 61 and the claw 62 is: for example, the protrusions 61 are fixedly mounted on the left and right sides of one end of the mounting block 33, and the protrusions 61 are fixedly mounted on the upper and lower sides of one end of the suction cup 7, and the claws 62 are the same. Such a staggered arrangement makes it possible for the mounting block 33 to be connected to the suction cup 7, only the sealing gaskets on the end faces of the two need to be pressed against each other, and then the claw 62 on one side can engage with the protrusion 61 on the other side so that both sides can be connected and fixed at the same time.

[0028] In more detail, a slope 63 is provided on one side of the protrusion 61, and the claw 62 is slidably connected to the slope 63, and can be engaged and pressed against the protrusion 61 through the slope 63. It should be noted that the opening directions of the slopes 63 of a pair of protrusions 61 at the same end are opposite, so that the claw 62 can be fixed by the slope 63 when rotating relative to each other.

[0029] In general, the driving assembly 8 includes a first motor 81, which is fixedly installed on one side of the workbench 1. A slide rail 82 is fixedly installed on the inner side of the workbench 1. A connecting block 83 is slidably connected to the slide rail 82. The shaft end of the first motor 81 is located in the slide rail 82 and is fixedly connected to a screw rod 84. The connecting block 83 is threadedly connected to the screw rod 84. The first motor 81 drives the connecting block 83 to move through the screw rod 84, thereby being able to translate and drive the suction cup 7 to adsorb the circuit board.

[0030] Finally, the adjustment assembly 9 includes a connecting rod 91 slidably connected inside the connecting block 83, one end of the connecting rod 91 is fixedly connected to the mounting plate 2, and a protrusion 92 is provided on its side, and a second motor 93 is fixedly installed on the other side of the workbench 1, and the axial end of the second motor 93 passes through the workbench 1 and is fixedly connected to a round rod, and a plurality of recesses 94 are provided on the periphery of the round rod, and the protrusion 92 is clamped with the recess 94 and slidably connected thereto.

[0031] In more detail, by utilizing the sliding effect between the protrusion 92 and the recessed portion 94, the connection block 83 does not affect the height of the suction cup 7 when it moves in translation. Then, by utilizing the clamping effect between the protrusion 92 and the recessed portion 94, the second motor 93 drives the connecting rod 91 to rise and fall, thereby making the height of the suction cup 7 adjustable, thereby facilitating the movement of the circuit board from the conveyor belt 4 to the collection box 5.

[0032] Working mode: When working, place the point circuit board on the conveyor belt 4, and the conveyor belt 4 rotates toward one end of the suction cup 7. While the conveyor belt 4 rotates, the first motor 81 drives the screw rod 84 to drive the connecting block 83 to translate, and move the suction cup 7 to the top of the circuit board;

[0033] Then, when the circuit board is about to be transported to the bottom of the suction cup 7, the second motor 93 drives the round rod to rotate, and then the concave portion 94 drives the connecting rod 91 to descend so that the suction cup 7 and the circuit board are attached. At this time, the suction cup 7 can absorb the circuit board through the action of the external air compressor, and repeat the above-mentioned translation and lifting operations to move the circuit board into the collection box 5;

[0034] Finally, by rotating the suction cup 7 to disengage the claw 62 on the end surface of the suction cup 7 from the protrusion 61 on the end surface of the mounting block 33, the suction cup 7 can be removed and replaced.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
