Description

Technical Field

[0001] The invention relates to the technical field of parts assembly, in particular to an automatic feeding and fool-proof assembly device. Background Art

[0002] The box is mainly divided into a box body and a cover body, and the two are fixed by splicing. Commonly used splicing methods mainly include: bolt fixing, snap fixing, and connecting rod connection.

[0003] The specific method of connecting the connecting rod is as follows: the box body and the cover body are both provided with a butt joint groove for the connecting rod to engage with, wherein the connecting rod is a round iron column, and the butt joint groove is a round groove, and the butt joint grooves on the box body and the cover body are interference fit with the connecting rod, so that the box body and the cover body are assembled and fixed. When the diameters of the butt joint grooves on the box body and the cover body are different, the connecting rod is also divided into a first rod body that cooperates with the cover body and a second rod body that butts with the box body.

[0004] Because the docking grooves on the box body and the cover body are both interference fit, if they are pressed in manually, they can only be pressed one at a time, which is inefficient. In addition, the first rod body is matched with the cover body and the second rod body is matched with the box body to achieve the effect of assembly and fixation. However, it takes a long time to distinguish between the first rod body and the second rod body each time they are assembled.

[0005] In order to solve the above technical problems, the inventor has designed an automatic feeding and fool-proof assembly device, and the present invention has been produced since then. Summary of the invention

[0012] The further configuration is as follows: the transfer component includes a transfer seat fixed to one end of the fixed seat near the middle of the second support plate, a first material conveying channel opened on the transfer seat from a direction away from the second support plate to a direction close to the second support plate, a transfer channel opened from a direction away from the middle of the second support plate to a direction close to the second support plate, a second material conveying channel opened on the transfer seat from a direction close to the second support plate to a direction away from the second support plate, a transfer block slidably connected to the transfer channel, and a telescopic cylinder fixed to the upper end surface of the fixed seat and with the output end fixed to the transfer block, one end of the input pipe is fixed to the transfer seat, and one end of the output pipe is fixed to the transfer seat.

[0013] It is further configured that: the transfer unit also includes a pressing part for pressing the connecting rod into the cover body, the pressing part includes a pressing base fixed to the upper end surface of the first support plate of the first support plate, and a pressing rod with one end fixed to the pressing base and the other end passing through the transfer seat and slidably connected to the second feed channel.

[0017] 1. By setting a base, a support column, a fixing plate, a lifting assembly, a transfer assembly, and a lifting cylinder, the connecting rod is transferred by the transfer assembly, and then the lifting assembly is driven to lift by the lifting cylinder, so that the connecting rod is accurately assembled into the docking groove of the cover body on the product seat, thereby improving the assembly efficiency;

[0018] 2. By setting the transfer piece and the press-in piece, the connecting rod enters the first feeding channel from the input pipe, the telescopic cylinder starts to drive the transfer block to slide along the transfer channel, pushes the connecting rod into the second feeding channel, slides into the docking groove of the cover from the second feeding channel, and presses the connecting rod into the docking groove through the press-in piece. An interference fit is achieved during product assembly;

[0019] 3. By setting up fool-proof parts, when the sizes of the docking grooves of the cover body and the box body are different, the diameters of the two ends of the connecting rod are different. The connecting rod is made of magnet material and has two magnetic poles at both ends. When the right input pipe of the connecting rod enters the first feeding channel, the magnetic pole of the first fool-proof magnet under the feeding channel and one end of the connecting rod (the one end here refers to the end where the connecting rod and the docking groove of the cover body are assembled) are opposite, and the two opposite poles attract each other. When the other end of the connecting rod is put in, the two magnetic poles are the same, and the same poles repel each other, driving the connecting rod to flip, and the telescopic cylinder drives the rotating block to turn. The connecting rod is pushed to the second feeding channel. At this time, the magnetic pole of the second anti-foolproof magnet is exactly the same as the magnetic pole of one end of the connecting rod (the one end here refers to the end where the connecting rod and the docking groove of the cover body are assembled). The two repel each other with the same polarity. At this time, the end of the connecting rod that is adsorbed by the second anti-foolproof magnet is the end that is assembled with the docking groove of the box body, and the end of the connecting rod away from the second anti-foolproof magnet is the first end that is assembled with the docking groove driven by the cover body. Through the press-in piece, the connecting rod is driven to be pressed into the docking groove of the cover body, which prevents the connecting rod from getting stuck during the transportation process, thereby having an anti-foolproof effect.

The fiber optic sensor 71 is used to sense whether a connecting rod passes through, and the grating sensor 72 is used to sense whether the first support plate 61 passes through.

[0038] The working steps of this embodiment are as follows:

[0039] S1: Connect the power supply, put four connecting rods into four input pipes 51 respectively, and the connecting rods enter the first material delivery channel 542 along the input pipes 51;

[0040] S2: After the connecting rod enters the first feeding channel 542, the first foolproof magnet 561 matches the magnetic poles of the connecting rod. By using the magnetic pole characteristics of the first foolproof magnet 561 and the connecting rod, the end of the connecting rod assembled with the cover body docking groove has the opposite magnetic pole to the first foolproof magnet 561, and the two attract each other with opposite poles.

[0041] S3: The optical fiber sensor 71 senses the passage of the connecting rod and transmits the signal to the first receiving controller and the second receiving controller 74. The first control receiver controls the telescopic cylinder 547 to move, pushes the transfer block 546 to drive the connecting rod to move along the transfer channel 543 to above the second material delivery channel 545, and the second control receiver controls the lifting cylinder 4 to move, driving the first support plate 61 and the second support plate 62 to descend.

[0042] S4: The connecting rod is transported to the top of the second feeding channel 545, and the second foolproof magnet 562 matches the magnetic poles of the connecting rod. By using the magnetic pole characteristics of the second foolproof magnet 562 and the connecting rod, the end of the connecting rod assembled with the docking groove of the box body is opposite to the magnetic pole of the second foolproof magnet 562, and the two are attracted by opposite poles.

[0043] S5: The lifting cylinder 4 drives the first support plate 61 and the second support plate 62 to slide along the support column 2 and press downward, and the second receiving seat 66 of the first support plate 61 abuts against the second limiting seat 64. At this time, the second support plate 62 stops moving downward, and the lifting cylinder 4 continues to drive the first support plate 61 to press downward;

[0044] S6: The first support plate 61 is pressed downward, which drives the spring 69 to be compressed, and the distance between the first support plate 61 and the second support plate 62 becomes smaller. The pressing rod 552 presses the connecting rod into the docking groove of the cover along the second material feeding channel 545, completing the interference fit between the connecting rod and the docking groove of the cover;

[0045] S7: The grating sensor 72 senses the passage of the first support plate 61 and transmits the signal to the first receiving controller and the second receiving controller 74. The first receiving controller receives the signal from the grating sensor 72 and controls the lifting cylinder 4 to drive the first support plate 61 and the second support plate 62 to rise to the starting position. At the same time, the second receiving controller 74 receives the signal from the grating sensor 72 and controls the telescopic cylinder 547 to drive the transfer block 546 to retract to the starting position.

[0046] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
