[0001] The utility model relates to the technical field of circuit board equipment, in particular to a circuit board taking device. Background Art

[0002] During the production process of circuit boards, a board suction mechanism is required to move the circuit boards between different processing equipment. Currently, a suction box is usually used to suck and move the circuit boards. The suction box has multiple air holes on one side for sucking the circuit boards. The arrangement of the air holes needs to avoid the hollow positions of the circuit boards. The air in the suction box is extracted by a vacuum generator such as a vacuum pump, forming a negative pressure between the air holes and the circuit boards, so that the suction disk firmly adsorbs the circuit boards.

[0033] During the production process of circuit boards, a board suction mechanism is required to move the circuit boards between different processing equipment. Currently, a suction box is usually used to suck and move the circuit boards. The suction box has multiple air holes on one side for sucking the circuit boards. The arrangement of the air holes needs to avoid the hollow positions of the circuit boards. The air in the suction box is extracted by a vacuum generator such as a vacuum pump, forming a negative pressure between the air holes and the circuit boards, so that the suction disk firmly adsorbs the circuit boards.

[0034] The arrangement and aperture of the air holes of the suction box need to be changed for circuit boards of different types and shapes. Therefore, one suction box can only be used to absorb one type of circuit board. The suction box needs to be redesigned every time the type of circuit board is changed.

[0035] To solve the above problems, please refer to Figure 3 The board taking device 100 proposed by the utility model comprises an air suction box 110, which has an air venting cavity 110a and a plurality of air holes 110b connected with the air venting cavity 110a, and the air suction box 110 is used to suck the circuit board;

[0036] The connecting plate 120 is detachably connected to the air suction box 110 and covers part of the air holes 110b.

[0037] The technical solution of the utility model adopts a detachable and replaceable connecting plate 120 connected to the side of the suction box 110 with the air hole 110b. When the board taking device 100 sucks different circuit boards, it is only necessary to remove the current connecting plate 120 from the suction box 110 and replace it with the corresponding connecting plate 120. Compared with processing and designing the suction box 110, processing and designing the connecting plate 120 has the advantages of being faster and less costly.

[0038] Specifically, since the processing methods used to design the air suction box 110 for different types of circuit boards are different, for example, the diameter of the air hole 110b of the air suction box 110 used in the soft circuit board is 1.2 mm, and the center hole needs to be processed, and the diameter of the air hole 110b of the air suction box 110 used in the hard circuit board is 3 mm, and the hole distribution is uneven, and a gong bed is usually used for processing, resulting in complex production of the air suction box 110. However, the present application uniformly uses laser processing to process the connecting plate 120. Since the laser processing method is fast and simple, and can process holes of any position and size, the present application has the beneficial effect of being faster and lower in cost.

[0039] It should be noted that, in one embodiment, the connecting plate 120 is glued to the suction box 110 by glue, which is convenient for disassembly and replacement. In other embodiments, the connecting plate 120 can be connected to the suction box 110 by threaded connection or snap connection. It only needs to meet the requirements that the connecting plate 120 can be detachably connected to the suction box 110, which is not limited here. In addition, the plate removal device 100 also includes a driving component 160, which is used to drive the suction box 110 to move.

[0040] In the embodiments of the present invention, please refer to Figure 3 The connecting plate 120 is penetrated by a plurality of through holes 120 a , and the through holes 120 a are connected to the air holes 110 b .

[0041] In this embodiment, for dense-hole plates, that is, circuit boards with more hollow parts, laser processing is used to expose the plate part on the dense-hole plates so that the suction box 110 can smoothly absorb the circuit board. Compared with the processing method using a gong bed, laser processing of the through hole 120a is faster and effectively improves production efficiency.

[0042] In one embodiment, in order to prevent the connection plate 120 from being too thick, which would weaken the suction force of the suction box 110 , or the connection plate 120 from being too thin and unable to withstand the suction force of the suction box 110 , the thickness of the connection plate 120 is 0.2 mm.

[0043] In the embodiments of the present invention, please refer to Figure 3 The connecting plate 120 is penetrated by an avoidance hole 120 b, and the avoidance hole 120 b is used to avoid the detection device 150 .

[0044] In this embodiment, it should be noted that the detection device 150 is used to detect the distance between the air suction box 110 and the circuit board. In order to avoid the connection plate 120 from interfering with the detection device 150, an avoidance hole 120b is provided on the connection plate 120 so that the detection device 150 can work normally. In other embodiments, multiple connection plates 120 can be used to connect with the air suction box 110 to avoid the position of the detection device 150, which is not limited here.

[0045] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The board taking device 100 further includes a buffer assembly 130, which is connected to a side of the suction box 110 away from the connecting plate 120, and is used to provide buffering for the suction box 110 when it moves toward the circuit board.

[0046] In this embodiment, when the suction box 110 is close to and abuts against the circuit board, the buffer assembly 130 provides a buffer to the suction box 110, so that the suction box 110 and the circuit board are in flexible contact, thereby preventing the suction box 110 from damaging the circuit board. At the same time, the buffer assembly 130 makes the suction box 110 abut against the circuit board as much as possible, and reduces the gas between the suction box 110 and the circuit board as much as possible, so that the suction box 110 can smoothly absorb the circuit board.

[0047] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The buffer assembly 130 includes a support shaft 131, an elastic member 132 and a sleeve 133. One end of the support shaft 131 is connected to a side of the air suction box 110 away from the connecting plate 120. The sleeve 133 is slidably sleeved outside the support shaft 131 and is used to be fixedly connected to the bracket 140. The elastic member 132 is used to make the sleeve 133 slide.

[0048] Specifically, in one embodiment, the sleeve 133 is a linear bearing, the elastic member 132 is a spring and is sleeved outside the support shaft 131, the sleeve 133 is fixedly connected to the bracket 140, and when the air suction box 110 abuts against the circuit board and continues to move toward the circuit board, the support shaft 131 moves in the sleeve 133 toward the direction away from the circuit board, driving the air suction box 110 to move in this direction, thereby achieving flexible contact between the air suction box 110 and the circuit board, thereby making the air suction box 110 fit the circuit board.

[0049] In the embodiments of the present invention, please refer to Figure 4 The buffer assembly 130 also includes an anti-slip component 135 , and one end of the support shaft 131 away from the suction box 110 is connected to the anti-slip component 135 , and the anti-slip component 135 is used to prevent the sliding sleeve 133 from being separated from the support shaft 131 .

[0050] In this embodiment, in order to prevent the support shaft 131 from detaching from the sliding sleeve 133 when the support shaft 131 slides in the sliding sleeve 133, an anti-detachment component 135 is provided to be connected to the end of the support shaft 131 away from the suction box 110, so as to ensure that the support shaft 131 cannot fall off the sliding sleeve 133 during the operation of the plate removing device 100, thereby ensuring the normal working state of the plate removing device 100.

[0051] In the embodiments of the present invention, please refer to Figure 4 The buffer assembly 130 further includes a protective sleeve 134 , which is sleeved outside the support shaft 131 and the elastic member 132 and connected to the suction box 110 .

[0052] In this embodiment, in order to prevent dirt generated when the support shaft 131 and the sliding sleeve 133 slide and contaminate the circuit board, a protective cover 134 is provided to be sleeved outside the support shaft 131. The protective cover 134 not only collects dirt, but also limits the support shaft 131. When the displacement of the support shaft 131 sliding away from the circuit board is too long, the protective cover 134 abuts against the sliding sleeve 133, thereby restricting the sliding of the support shaft 131.

[0053] In the embodiments of the present invention, please refer to Figure 2 The air suction box 110 is provided with a first connecting portion 112 , the protective cover 134 has a second connecting portion 1341 , one end of the support shaft 131 is connected to the first connecting portion 112 , and a bolt passes through the first connecting portion 112 and the second connecting portion 1341 to connect the protective cover 134 to the air suction box 110 .

[0054] In this embodiment, in order to strengthen the connection between the protective cover 134 and the air suction box 110, a first connecting portion 112 is provided on the air suction box 110 to be connected to the protective cover 134, and the protective cover 134 and the air suction box 110 are detachably connected by bolts. The threaded connection between the protective cover 134 and the air suction box 110 facilitates the removal of the protective cover 134 when it needs to be cleaned.

[0055] In the embodiments of the present invention, please refer to Figure 2 and Figure 3 The air suction box 110 is penetrated by a second mounting hole 110c, the second mounting hole 110c and the ventilation cavity 110a are independent of each other, and a detection device 150 is disposed in the second mounting hole 110c, and the detection device 150 is used to detect the distance between the air suction box 110 and the circuit board.

[0056] In this embodiment, when the suction box 110 moves toward the direction close to the circuit board, the detection device 150 can detect the distance between the suction box 110 and the circuit board, thereby controlling the opening of the suction device connected to the suction box 110. In addition, the suction box 110 is also provided with a mounting portion 113, the mounting portion 113 has a first mounting hole 113a connected to the ventilation cavity 110a, and the mounting portion 113 is used to install a control valve, and the control valve is used to inject gas into the ventilation cavity 110a, or to restore the negative pressure state in the ventilation cavity 110a to the same state as the external atmospheric pressure in other ways, so that the suction box 110 puts down the circuit board.

[0057] It should be noted that when the connecting plate 120 is connected to the air suction box 110, the second mounting hole 110c and the avoidance hole 120b are located at the same position. The detection device 150 may use a photoelectric sensor, an ultrasonic sensor, an infrared sensor, etc., which is not limited here.

[0058] In the embodiments of the present invention, please refer to Figure 3 The diameters of the multiple air holes 110b are all 3 mm.

[0059] In this embodiment, in order to avoid the hole diameter of the air hole 110b being too large, resulting in insufficient suction and failure to absorb the circuit board, or the hole diameter of the air hole 110b being too small, resulting in excessive suction and damage to the circuit board when sucking the circuit board, the hole diameter of the air hole 110b is set to 3 mm to avoid the above two problems.

[0060] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
