DETAILED DESCRIPTION
[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.
[0028] like Figure 1-Figure 7 As shown, the utility model provides a fully automatic pressing and assembling device for assembled stool legs, the stool legs include a stool head and a stool cap, the pressing and assembling device includes a plurality of clamping mechanisms 2, a fixing mechanism 4 and a first manipulator 3 (a six-axis manipulator can be used, which is the prior art, and the specific working principle is not described in detail here);
[0029] The clamping mechanism 2 is used to fix the stool head;
[0030] The fixing mechanism 4 includes a support frame 41, a first driving member 44 (which can be set as a cylinder), and a plurality of first fixing components 42 fixed to the stool head and a plurality of second fixing components 43 fixed to the stool cap, which are arranged on the support frame 41. The output end of the first driving member 44 is fixedly connected to the second fixing component 43.
[0031] The first manipulator 3 is used to drive the fixing mechanism 4 to move the stool head fixed by the first fixing component 42 to the clamping mechanism 2 and to make each second fixing component 43 located directly above a clamping mechanism 2;
[0032] When the first manipulator 3 drives each second fixing assembly 43 to be located directly above a clamping mechanism 2, the first driving member 44 is used to drive the second fixing assembly 43 to move close to the clamping mechanism 2, so that the stool cap and the stool head are connected by interference fit;
[0033] When in use, the first manipulator 3 drives the fixing mechanism 4 to move, so that the first fixing component 42 and the second fixing component 43 respectively pick up and fix a plurality of stool heads and stool caps, and then the first manipulator 3 is adjusted to drive the fixing mechanism 4 to move, so that the stool heads on the first fixing component 42 are transferred to the clamping mechanism 2 for fixation, and then the first manipulator 3 is adjusted to drive each second fixing component 43 to be located directly above a clamping mechanism 2, and finally the first driving member 44 is adjusted to drive the second fixing component 43 to move close to the clamping mechanism 2, so that the stool cap and the stool head are interference connected, thereby completing the fully automatic assembly of the stool cap and the stool head. Compared with the existing manual assembly, it greatly reduces people's labor intensity, improves the assembly speed and avoids the problem of loose clamping.
[0034] Specifically, Figure 2 and Figure 5 As shown, the clamping mechanism 2 includes a second driving member (here set as a cylinder), a first clamping plate 21 and a second clamping plate 22. The first clamping plate 21 and the second clamping plate 22 are both provided with a first groove adapted to the lower side of the outer wall of the stool head on the opposite side. The pressing assembly device also includes a limiting mechanism, which includes a base 6 and a blocking component 7. The base 6 is fixed to the lower side of the second clamping plate 22 facing the first clamping plate 21, and is used to support the stool head. The top surface of the base 6 is inclined to the side facing away from the second clamping plate 22, and the bottom surface of the stool head is an inclined surface, and the bottom surface of the stool head is in contact with the top surface of the base 6. The blocking component 7 is used to block the stool head on the base 6;
[0035] Here, a plurality of second clamping plates 22 are fixed on a bottom plate, and the bottom plate is driven to move by a second driving member, thereby driving a plurality of second clamping plates 22 to move synchronously, and the first clamping plate 21 is fixed on the support platform 1;
[0036] The first manipulator 3 drives the fixing mechanism 4 to move, so that the stool head fixed by the first fixing component 42 is placed on the base 6, and the bottom of the stool head is limited and blocked by the blocking component 7, so that it will not easily slide off the base 6, and at this time, one side of the outer wall of the stool head is in contact with the first groove of the second clamping plate 22;
[0037] Then synchronously adjust the first manipulator 3 and the second driving member to make the stool head and the second clamping plate 22 move synchronously close to the first clamping plate 21 until the second clamping plate 22 and the first clamping plate 21 fix the stool head. After the stool head is clamped and fixed by the first clamping plate 21 and the second clamping plate 22, adjust the first fixing assembly 42 to no longer fix the stool head.
[0038] Subsequently, by adjusting the first manipulator 3 to drive the second fixing assembly 43 to be located just above the clamping mechanism 2, and then adjusting the first driving member 44 to drive the second fixing assembly 43 to move close to the clamping mechanism 2, the base 6 can play a good supporting role for the stool head, avoiding the first driving member 44 driving the second fixing assembly 43 to move downward, thereby preventing the first clamping plate 21 and the second clamping plate 22 from having insufficient clamping force when the stool cap and the stool head are clamped, and preventing the stool head from sliding and affecting the final clamping assembly effect;
[0039] After the stool cap is assembled, the blocking component 7 is adjusted so that it no longer blocks the stool head, and then the second driving member is adjusted to move the second clamping plate 22 away from the first clamping plate 21. Since the bottom of the stool head and the top surface of the base 6 are both inclined surfaces, the assembled stool legs can automatically slide down and unload.
[0040] like Figure 5 As shown, the blocking assembly 7 includes a third driving member 71 (here set as a cylinder), a connecting plate 72 and a stopper 73. The output end of the third driving member 71 is fixedly connected to the connecting plate 72. The stopper 73 is fixedly installed on the top surface of the connecting plate 72. The stopper 73 is located at the lowest end side of the top surface of the base 6.
[0041] When the blocking assembly 7 is needed to block the stool head, the third driving member 71 is adjusted to drive the connecting plate 72 to move, thereby driving the stopper 73 to move, so that the top of the stopper 73 is higher than the lowest end of the top surface of the base 6, so that when the stool cap is assembled later, the stool head is always in a stable state and will not slide;
[0042] On the contrary, when the subsequently assembled stool legs are automatically unloaded, the third driving member 71 is adjusted to drive the connecting plate 72 to move, thereby driving the stop block 73 to move, so that the top end of the stop block 73 is lower than the lowest end of the top surface of the base 6, so that the stop block 73 no longer blocks the stool head (stool legs), thereby facilitating the automatic sliding unloading of the assembled stool legs.
[0043] like Figure 1-Figure 3 As shown, the press-fit assembly device also includes a fastening component 5 and a support platform 1, the clamping mechanism 2 is located on the support platform 1, the fastening component 5 includes a bracket, a fourth driving member (here set as a cylinder) and an insertion rod, the brackets are fixedly installed on both sides of the top surface of the support platform 1, the fourth driving member is fixedly installed on the top of the bracket, the output end of the fourth driving member is fixedly connected to the insertion rod, and the two sides of the support frame 41 are provided with card slots 45 adapted to the insertion rod at the positions opposite to the insertion rod;
[0044] When the second fixing assembly 43 is driven to be located above the clamping mechanism 2 by adjusting the first manipulator 3, the insertion rod and the card slot 45 are facing each other, and the fourth driving member is adjusted to drive the insertion rod to move so that it is inserted into the card slot 45, thereby completing the fixing of the support frame 41;
[0045] By setting the fastening assembly 5 to fix the support frame 41, it is avoided that when the first driving member 44 is adjusted to drive the second fixing assembly 43 to move close to the clamping mechanism 2, the support frame 41 is in a suspended state, causing the first manipulator 3 to be overloaded under the reaction of the first driving member 44, thereby ensuring the service life of the first manipulator 3.
[0046] like Figure 3 As shown, the first fixing assembly 42 includes a third clamping plate, a fourth clamping plate and a fifth driving member. The third clamping plate and the fourth clamping plate are both provided with a second groove adapted to the upper side of the outer wall of the stool head on one side. The second fixing assembly 43 is a suction cup, and the bottom of the suction cup is provided with a contour adapted to the top of the stool cap.
[0047] The principle of the first fixing component 42 clamping and fixing the stool head is the same as the clamping and fixing principle of the clamping mechanism 2, which will not be repeated here. The second fixing component 43 adopts a suction cup to absorb and fix the stool cap. Since the bottom of the suction cup is provided with a contour adapted to the top of the stool cap, it can ensure that when the first driving member 44 drives the suction cup to move downward, the two ends of the stool cap are respectively in contact with the stool head and the suction cup, so that the stool cap and the stool head are stably interference fit.
[0048] like Figure 1 , Figure 2 and Figure 5 As shown, the pressing assembly device also includes a conveyor belt 8. A plurality of through holes are opened on the top surface of the support platform 1. The through holes are larger than the size of the stool legs. The through holes are located directly below the first clamping plate 21 and the second clamping plate 22. A conveyor belt 8 is provided directly below the support platform 1.
[0049] By opening a through hole on the top surface of the support platform 1, when the stool cap and the stool head are snap-fitted and assembled, the first clamping plate 21 and the second clamping plate 22 are adjusted to no longer clamp and fix the stool legs. The stool legs slide from the base 6 through the through hole and fall onto the conveyor belt 8, completing the automatic unloading work. The automatic loading work of the stool head can be performed again later.
[0050] like Figure 1 and Figure 6 As shown, the pressing assembly device also includes a loading platform 9, a second manipulator 12, a first injection molding machine 10 for producing stool caps, and a second injection molding machine 11 for producing stool heads. The output end of the second manipulator 12 is fixedly connected to a material-picking component fixed to the stool cap (the material-picking component here can also be set as a suction cup). The second manipulator 12 is used to drive the material-picking component to move and transfer the injection-molded stool cap to the loading platform 9. The loading platform 9 includes a loading plate 91 and a plurality of profiling members 92 adapted to the stool cap provided on the top surface of the loading plate 91. The profiling members 92 are used to support the stool cap produced by the first injection molding machine 10 taken out by the material-picking component, so as to facilitate the subsequent material picking by the second fixing component 43.
[0051] The working principle of the first injection molding machine 10 and the second injection molding machine 11 is the existing technology and will not be described in detail here. After the first manipulator 3 drives the first fixed component 42 to pick up the stool head produced by the second injection molding machine 11, the stool cap on the profiling part 92 is picked up by the second fixed component 43. By setting the second manipulator 12, the stroke of the first manipulator 3 can be reduced (only the stool head on the second injection molding machine 11 needs to be directly picked up, avoiding the first manipulator 3 from directly picking up the stool cap of the first injection molding machine 10 at the same time), and the first manipulator 3 and the second manipulator 12 are used together, which is more efficient;
[0052] The entire equipment can realize the automatic injection molding of the stool head and stool cap to the automatic unloading and assembly, and realize the fully automatic assembly of the stool legs.
[0053] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
