A fully automatic assembly production line for brushes

Abstract

The present invention discloses a fully automatic assembly production line for brushes. The fully automatic assembly production line for brushes can complete the precise material picking, positioning, placement and assembly of a base, a top plate, a brush cloth and a shell by arranging an assembly table, a rotating plate, a support plate, a loading mechanism, a first assembly mechanism, a first manipulator and a second assembly mechanism, thereby completing the fully automatic processing and assembly of the brushes, which not only avoids the trouble and labor of manual assembly one by one and improves the efficiency, but also arranges the first material picking component and the second material picking component in the first assembly mechanism on the same side of the support block, and an elastic telescopic part is arranged between the second material picking component and the support block, which can not only reduce the number of times the first manipulator is adjusted to rotate to pick up materials, but also plays a role in pressing the brush cloth and the top plate during the initial assembly of the shell, so as to avoid the brush cloth and the top plate being offset when the brush cloth is manually placed or the shell is moved down for assembly and just contacts with the brush cloth, causing the brush cloth stripes to bend, thereby resulting in an unsightly assembled product.

Description

Technical Field

[0001] The invention relates to the technical field of brush production equipment, in particular to a full-automatic brush assembly production line. Background Art

[0002] like Figure 9-13 As shown, a brush currently assembled by our company consists of a base 91, a shell 92, a brush cloth 93 and a top plate 94. A plurality of first clamping blocks 921 are provided at the bottom end of the shell 92, and a plurality of second clamping blocks 922 are provided on the inner wall of the bottom of the shell 92. The top surface of the base 91 is provided on a concave surface adapted to the top plate 94. A plurality of first clamping grooves 911 for accommodating the first clamping blocks 921 are provided on the top surface of the outer edge of the bottom of the base 91. A plurality of guide ribs 912 are vertically provided on the outer wall of the base 91, and a second clamping groove 9121 is provided at one end of some guide ribs 912 near the outer edge of the bottom of the base 91. The assembly sequence is to place the top plate 94 on the top surface of the base 91, then lay the brush cloth 93 on the top plate 94, and finally use the shell 92 to cover it on the base 91 and fix it, and fix the brush cloth 93 between the shell 92 and the base 91.

[0003] At present, the assembly of the brush is completed by manual assembly, which is not only inefficient, but also the manual placement of the brush cloth 93 cannot guarantee accurate positioning every time. In addition, when installing the sleeve 92, since the surface of the brush cloth 93 is striped, the sleeve 92 is in contact with the brush cloth 93, and the brush cloth 93 cannot be fixed by manual operation when pressing the sleeve 92, which will cause the brush cloth 93 to partially shift in position and cause the stripes of the brush cloth 93 to bend, thereby affecting the appearance of the brush cloth 93. At the same time, when assembling the sleeve 92 on the base 91, it is necessary not only to press the sleeve 92 down for assembly, but also to press both sides of the sleeve 92 to ensure that the first block 921 can smoothly enter the first slot 911 to avoid the side wall of the sleeve 92 turning outward after assembly. The manual labor intensity is very high. Summary of the invention

DETAILED DESCRIPTION

[0037] 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 explained in conjunction with specific embodiments below. 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 making any creative work all belong to the protection scope of the present invention.

[0038] The present invention provides a fully automatic brush assembly production line, such as Figure 9-13 As shown, the brush includes a base 91, a casing 92, a brush cloth 93 and a top plate 94. The surface of the brush cloth 93 is striped. The casing 92 is hollow inside and open at both ends. A plurality of first clamping blocks 921 are provided at the bottom end of the casing 92. A plurality of second clamping blocks 922 are provided around the inner wall of the bottom of the casing 92. A concave surface matching the top plate 94 is provided on the top surface of the base 91. A plurality of first clamping grooves 911 for accommodating the first clamping blocks 921 are provided on the top surface of the outer edge of the bottom of the base 91. A plurality of guide ribs 912 are vertically provided around the outer wall of the base 91. A second clamping groove 9121 is provided on one end of some of the guide ribs 912 close to the outer edge of the bottom of the base 91.

[0039] Here, the second clamping block 922 and part of the guide rib 912 are set as a right-angled triangle as an example. At this time, the second clamping groove 9121 is adapted to the size of the second clamping block 922, and the side surface corresponding to a right-angled side of the guide rib 912 is in contact with the outer wall of the base 91, and the side surface corresponding to a right-angled side of the second clamping block 922 is in contact with the inner wall of the casing 92. The hypotenuse of the second clamping block 922 is directly opposite to the hypotenuse of the guide rib 912. When the casing 92 is gradually fitted with the base 91, the outer wall of the casing 92 gradually expands outward until the second clamping block 922 of the right-angled triangle enters the second clamping groove 9121. At this time, the top surface corresponding to the other right-angled side of the second clamping block 922 is in contact with the bottom surface of the inner wall of the second clamping groove 9121, that is, at this time, the casing 92 is completely buckled on the base 91;

[0040] like Figure 1-Figure 8 As shown, the fully automatic assembly production line includes an assembly table 1, a rotating plate 2, at least three support plates 3, a loading mechanism 11, a first assembly mechanism 5, a first manipulator 4 and a second assembly mechanism 7;

[0041] The assembly table 1 is provided with a loading area, a first assembly area and a second assembly area;

[0042] The rotating plate 2 is rotatably arranged on the assembly table 1, and can be driven to rotate by a motor;

[0043] The support plates 3 are equidistantly arranged on the rotating plate 2. When the rotating plate 2 rotates, each support plate 3 passes through the loading area, the first assembly area and the second assembly area in sequence.

[0044] The loading mechanism 11 is used to transfer the base 91 to the support plate 3 in the loading area;

[0045] The first assembly mechanism 5 includes a support block 51, a first driving member 52, at least one first material picking component 54 for grabbing the casing 92, at least one second material picking component 55 for grabbing the top plate 94 and at least one third material picking component 57 for grabbing the brush cloth 93, the first material picking component 54 and the second material picking component 55 are located on the same side of the support block 51, each second material picking component 55 is located between a first material picking component 54, the second material picking component 55 and the third material picking component 57 are located on different sides of the support block 51, an elastic telescopic member 551 is provided between the second material picking component 55 and the support block 51 (the elastic telescopic member 551 here can be set as a spring telescopic sleeve, which is an existing structure and is not described here), when the elastic telescopic member 551 is in a natural state, the height position of the second material picking component 55 is lower than the height position of the first material picking component 54;

[0046] Specifically, a first driving member 52 (which may be set as a cylinder here) and a second side frame 56 are fixedly installed on both sides of the support block 51 (the two sides facing each other are taken as an example here), the output end of the first driving member 52 is fixedly connected to the first side frame 53, a first material taking assembly 54 and a second material taking assembly 55 (four of each are set as an example in the figure here), are fixedly installed on the side of the first side frame 53 facing away from the second side frame 56, and a third material taking assembly 57 (four of each are set as an example in the figure here), is fixedly installed on the side of the second side frame 56 facing away from the first side frame 53;

[0047] The output end of the first manipulator 4 is fixedly connected to the support block 51. The first manipulator 4 is used to drive the first assembly mechanism 5 to move, and the top plate 94 grabbed by the second material picking component 55, the brush cloth 93 grabbed by the third material picking component 57 and the sleeve 92 grabbed by the first material picking component 54 are placed on the base 91 in sequence. When the first driving member 52 drives the first material picking component 54 to move and initially sleeve the sleeve 92 on the base 91, the second material picking component 55 contacts the brush cloth 93, and the elastic telescopic member 551 is gradually compressed;

[0048] The second assembly mechanism 7 includes a pressing assembly and a pressing assembly. When the support plate 3 moves from the first assembly area to the second assembly area, the pressing assembly drives the casing 92 to continuously move downward. When the pressing assembly contacts the casing 92, the pressing assembly presses the casing 92, so that the first clamping block 921 on the casing 92 is tilted toward the center of the casing 92 and faces the first clamping groove 911.

[0049] Specifically, the pressing assembly includes a sliding frame 71, a fourth driving member 72 (which can be set as a cylinder here), a movable plate 73 and a pressing block 74. The bottom of the pressing block 74 is provided with a groove that matches the size of the casing 92. The sliding frame 71 is slidably arranged on the slide rail 8 described below (the slide rail 8 is provided here to prevent the sliding frame 71 from blocking the rotation of the rotating plate 2), the fourth driving member 72 is fixed to the sliding frame 71, the output end of the fourth driving member 72 is fixedly connected to the movable plate 73, and the pressing block 74 is fixedly installed at the bottom of the movable plate 73 (four pressing blocks 74 are taken as an example for explanation here);

[0050] Thus, there are four pressing assemblies, each of which includes a fifth driving member 76 (which can be set as a cylinder), a first pressing plate 75 and a second pressing plate 77 (the first pressing plate 75 and the second pressing plate 77 are also made of soft materials to prevent damage to the casing 92), the output end of the fifth driving member 76 is fixedly connected to the second pressing plate 77, the fifth driving member 76 and the first pressing plate 75 are both fixed to the bottom of the movable plate 73 (in addition, the first pressing plate 75 can also be driven to move by another fifth driving member 76, and the two fifth driving members 76 respectively drive the first pressing plate 75 and the second pressing plate 77 to move closer to or away from each other, and the use of one fifth driving member 76 can be reduced by setting the position of the first pressing plate 75 fixed, and the lower pressing block 74 is located between the first pressing plate 75 and the second pressing plate 77;

[0051] It should be noted that: when the first driving member 52 drives the casing 92 to move downward and be assembled on the base 91, the load of the first manipulator 4 cannot completely press the casing 92 onto the periphery of the base 91 at one time, and the first assembly mechanism 5 cannot be provided with a pressing component to press the casing 92, so the casing 92 is assembled in two steps here;

[0052] Here, two first clamping blocks 921 are symmetrically arranged on both sides of the bottom end of the casing 92, and two first clamping grooves 911 are symmetrically opened on the top surface of the outer edge of the bottom of the base 91, wherein the distance between the first clamping blocks 921 on the two sides is slightly smaller than the distance between the first clamping grooves 911 on the two sides, and the first clamping blocks 921 symmetrically arranged on both sides are arranged in an inner eight shape, and the first clamping grooves 911 symmetrically opened on both sides are arranged in an outer eight shape. When the casing 92 is completely sleeved on the base 91, the first clamping block 921 enters the first clamping groove 911 more smoothly. Through the first clamping block 921 and the first clamping groove 911 arranged in this way, the first clamping block 921 and the first clamping groove 911 cooperate to limit the outer wall of the casing 92, which can prevent the outer edge of the bottom end of the casing 92 from turning outward. Four bases 91, four casings 92, four brush cloths 93 and four top plates 94 are processed as a group as an example for explanation:

[0053] When the brush product needs to be assembled, the four bases 91 are transferred to the support plate 3 in the loading area on the assembly table 1 through the loading mechanism 11. At this time, the first manipulator 4 drives the first assembly mechanism 5 to grab the shell 92, the brush cloth 93 and the top plate 94 respectively;

[0054] Then, the rotating plate 2 is driven to rotate, so that the support plate 3 with the base 91 is placed thereon moves to the first assembly area, and then the first manipulator 4 is adjusted to drive the support block 51 to move, and the top plate 94 grabbed by the second material taking assembly 55 is placed on the concave surface of each base 91;

[0055] Then adjust the first manipulator 4 so that it drives the support block 51 to move so that the brush cloth 93 grabbed by the third material taking component 57 is placed opposite to the base 91 and the top plate 94;

[0056] Then, the first manipulator 4 is adjusted to drive the support block 51 to move so that the shell 92 grabbed by the first material picking component 54 moves to the top of the base 91. Since the height position of the second material picking component 55 is lower than the height position of the first material picking component 54, and an elastic telescopic member 551 is provided between the second material picking component 55 and the support block 51, when the first driving member 52 is adjusted to drive the first material picking component 54 and the second material picking component 55 to move downward, the second material picking component 55 first contacts the brush cloth 93 and presses the brush cloth 93 tightly to make it close to the top plate 94. When the first material picking component 54 and the second material picking component 55 continue to move downward, the elastic telescopic member 551 is gradually compressed from a natural state, and then the first material picking component 54 gradually moves downward to initially cover the shell 92 on the periphery of the base 91, but the shell 92 is not completely engaged with the base 91, so that when the subsequent rotating plate 2 is rotated, there will be no relative movement between the shell 92 and the base 91, and the shell 92 will not fall off, which is convenient for the subsequent stable and accurate assembly of the shell 92 (such as Fig.11 As shown, at this time, the brush cloth 93 is located between the casing 92 and the base 91, but the brush cloth 93 is not drawn in the figure);

[0057] After the casing 92 is initially buckled onto the base 91, the first manipulator 4 is adjusted to drive the first assembly mechanism 5 to carry out the material collection work of the top plate 94, casing 92 and brush cloth 93 that need to be assembled in the next round, and then the rotating plate 2 is adjusted to rotate so that the support plate 3 in the first assembly area where the casing 92 is initially assembled on the base 91 moves to the second assembly area, and then the second assembly mechanism 7 is adjusted to make each lower pressing block 74 face a casing 92, and then the fourth driving member 72 is adjusted to drive the movable plate 73 and the lower pressing block 74 to move downward until the groove at the bottom of the lower pressing block 74 contacts the top of the casing 92. At this time, the first pressing plate 75 and the casing 9 2, and then adjust the fifth driving member 76 to drive the second pressing plate 77 to move close to the other side of the outer wall of the casing 92 until it abuts against it, so that the first pressing plate 75 and the second pressing plate 77 squeeze the two sides of the casing 92, and finally, adjust the fourth driving member 72 to drive the movable plate 73 and the lower pressing block 74 to continue to move downward until the first clamping block 921 smoothly enters the first clamping groove 911, that is, the full-automatic assembly of the brush product is completed (if there is no pressing component to press the casing 92, and only the lower pressing component is used to press the casing 92 downward, the first clamping block 921 will not be able to enter the first clamping groove 911);

[0058] Here, the first material picking component 54 and the second material picking component 55 are located on the same side of the support block 51, which can not only pick up materials from the casing 92 and the top plate 94 at the same time, but also can reduce the number of times the first manipulator 4 is adjusted to rotate and pick up materials compared to the first material picking component 54, the second material picking component 55 and the third material picking component 57 are respectively located on three sides of the support block 51, and can also play a role in pressing the brush cloth 93 and the top plate 94 during the initial assembly of the casing 92, so as to avoid the inaccurate position of the brush cloth 93 being manually placed or the casing 92 being moved down for assembly and just in contact with the brush cloth 93, so that the positions of the brush cloth 93 and the top plate 94 are offset, resulting in the bending of the stripes of the brush cloth 93, resulting in the inaccurate assembly position of the final brush cloth 93, and the appearance of unsightly defective products, which not only improves the processing and assembly efficiency of the brush, but also ensures the quality of its automated processing and assembly, that is, ensures the beauty of the product;

[0059] It should also be noted that when the brush cloth 93 is large enough and its outer edge can just fit between the second block 922 and the second slot 9121 (here the size of the second slot 9121 can be slightly larger than the size of the second block 922), the second material picking assembly 55 presses the brush cloth 93, so that the brush cloth 93 can be stably placed on the base 91 and the top plate 94 to prevent it from shifting, thereby ensuring that the brush cloth 93 is evenly stuck between the second block 922 and the second slot 9121, making the brush cloth 93 more stably fixed and preventing it from wrinkling during use, thereby ensuring the product quality of the brush.

[0060] like Figure 1 , Figure 5 and Figure 6As shown, each support plate 3 is provided with a plurality of through holes 31. When the base 91 is located on the support plate 3, at least one through hole 31 is symmetrically provided on both sides directly below the bottom edge of the base 91 (two through holes are symmetrically provided on both sides as an example here). The fully automatic assembly production line also includes a lifting mechanism 6. The first assembly area and the second assembly area are both provided with a lifting mechanism 6. The lifting mechanism 6 includes a lifting member 61 (which can be set as a cylinder here), a cross plate 62 and a plurality of push rods 63. The output end of the lifting member 61 is fixedly connected to the cross plate 62. The output end of the cross plate 62 is fixedly connected to the plurality of push rods 63. When the support plate 3 is located in the first assembly area and the second assembly area, the lifting member 61 drives each push rod 63 to pass through a through hole 31 respectively to push the base 91 away from the support plate 3.

[0061] When the support plate 3 with the base 91 is transferred to the first assembly area and the second assembly area, and at this time a push rod 63 is facing a through hole 31, the lifting member 61 drives the cross plate 62 to move close to the rotating plate 2, and the cross plate 62 drives the push rod 63 to move, so that the push rod 63 passes through the through hole 31 to lift each base 91, cooperate with the first driving member 52 to drive the casing 92 to move downward for preliminary assembly, and the fourth driving member 72 drives the casing 92 to move downward for complete buckling and assembly, so as to further speed up the assembly efficiency of the casing 92 and the base 91;

[0062] At the same time, by setting the lifting mechanism 6, it is possible to avoid using the first driving member 52 and the fourth driving member 72 alone to drive the sleeve 92 to fit the base 91 on the support plate 3. When there is a gap between the rotating plate 2 and the top surface of the assembly table 1, the rotating plate 2 will be squeezed and deformed, thereby avoiding the position deviation of the support plate 3, ensuring that the support plate 3 and the rotating plate 2 will not be subjected to force, thereby ensuring that the position of the base 91 on the support plate 3 will not be deviated, and ensuring the precise placement and assembly of the subsequent top plate 94, brush cloth 93 and sleeve 92.

[0063] like Figure 3 As shown, the second material picking component 55 is a suction cup, and the first material picking component 54 is a pneumatic claw, which includes a second driving member and at least two symmetrically arranged "Γ"-shaped supporting blocks. The second driving member drives the two supporting blocks to move closer to or away from each other. The supporting blocks have a horizontal portion and a vertical portion. The horizontal portions of the two supporting blocks are arranged back to back. When the vertical portion abuts against the inner wall of the casing 92, the horizontal portion abuts against the top surface of the casing 92. The horizontal portion and the vertical portion here are both made of soft materials to avoid crushing the casing 92.

[0064] By means of the first material picking assembly 54 arranged in this way, on the one hand, the two vertical parts move away from each other and abut against the inner wall of the sleeve 92 to complete the fixing and picking of the sleeve 92; on the other hand, when the first driving member 52 drives the horizontal part to move downward, the sleeve 92 can also be pressed downward so that it is initially sleeved on the periphery of the base 91.

[0065] like Figure 1As shown, a slide rail 8 is provided on the top surface of the assembly table 1, and a gap is provided between the bottom surface of the rotating plate 2 and the top surface of the assembly table 1. The size of the gap is greater than the height of the slide rail 8, so as to ensure that the slide rail 8 does not block the normal rotation of the rotating plate 2. A discharge hole 101 is provided on the top surface of the assembly table 1, and a conveyor belt 10 is provided directly below the discharge hole 101. The second assembly mechanism 7 is slidably provided on the slide rail 8, and the second assembly mechanism 7 reciprocates directly above the discharge hole 101 and directly above the support plate 3 of the second assembly area.

[0066] When the support plate 3 in the first assembly area on which the sleeve shell 92 is preliminarily assembled on the base 91 moves to the second assembly area, the second assembly mechanism 7 is driven to move along the slide rail 8 close to the support plate 3 so that the lower pressing block 74 is located directly above the sleeve shell 92 on the support plate 3. After the sleeve shell 92 is completely assembled on the base 91 by the second assembly mechanism 7 (the specific assembly method has been recorded above), the pressing assembly clamps the sleeve shell 92 and does not release it. At the same time, the fourth driving member 72 is adjusted to drive the sleeve shell 92 to move upward, so that the base 91 is separated from the support plate 3 and the positioning block 32 described below, and the automatic material removal of the assembled brush is completed. Finally, the second assembly mechanism 7 is adjusted. The assembly mechanism 7 moves along the slide rail 8 close to the discharge hole 101, so that the brush product is located directly above the discharge hole 101 (at this time, the turn plate 2 can also rotate normally, which is convenient for the support plate 3 in the next first assembly area to be transferred to the second assembly area for cyclic continuous assembly work), and then the pressing component is adjusted to no longer fix the sleeve 92 (brush), so that the assembled brush falls onto the conveyor belt 10 through the discharge hole 101. In this way, after the sleeve 92 is completely assembled on the base 91, the second assembly mechanism 7 is adjusted to reset and move to directly above the discharge hole 101, so that the assembled brush can be immediately removed from the support plate 3 and the subsequent unloading work can be completed.

[0067] like Figure 6 As shown, a plurality of vertical plates are provided on the top surface of the assembly table 1, on which rollers 14 are rotatably provided, and the rollers 14 are in contact with the bottom surface of the rotating plate 2. By providing the rollers 14, the rotating plate 2 can be supported, thereby further ensuring that the rotating plate 2 will not be deformed during the assembly of the brush, thereby ensuring that the assembly of the brush is carried out accurately.

[0068] like Figure 5 , Figure 6 and Fig.13 As shown, a bottom groove is provided at the bottom of the base 91, a plurality of positioning blocks 32 adapted to the bottom groove are provided on the top surface of the support plate 3, and a plurality of first limiting rods 33 are also provided on the top surface of the support plate 3. The first limiting rods 33 are located at the periphery of the positioning blocks 32, and the height position of the first limiting rods 33 is higher than the height position of the top surface of the positioning blocks 32;

[0069] By providing the first limiting rod 33, it is convenient to limit the brush cloth 93, so that after the brush cloth 93 is placed on the top plate 94, the outer edge of the brush cloth 93 abuts against the outer wall of the first limiting rod 33, thereby ensuring the accurate positioning and placement of the brush cloth 93 and preventing it from moving at will;

[0070] By setting the positioning block 32, the positioning and placement of the base 91 is facilitated. At the same time, when the push rod 63 passes through the through hole 31 to lift each base 91, the base 91 moves up along the positioning block 32 to ensure that the position of the base 91 will not shift. After the first assembly mechanism 5 preliminarily assembles the shell 92 and the base 91, when the push rod 63 is adjusted to move down and out of the through hole 31, the base 91 can move down along the positioning block 32 and return to the support plate 3, ensuring that the subsequent second assembly mechanism 7 can accurately perform processing and assembly work.

[0071] like Figure 1 and Figure 7 As shown, the base 91 is injection molded by an injection molding machine, and the feeding mechanism 11 includes a second manipulator and a transfer component, and the transfer component includes a support frame 111, a rotating rod 113 is rotatably installed on the support frame 111, and a motor 112 is fixedly installed on one side of the support frame 111, and the output end of the motor 112 is fixedly connected to the rotating rod 113, and a first bearing platform 114 is fixedly installed on the outer wall of the rotating rod 113, and at least one group of first limiting structures and a clamping structure (the clamping structure here can be set as a pneumatic clamping claw, which is an existing structure, and the principle is not repeated here) is provided on the top surface of the first bearing platform 114, and the first limiting structure includes a plurality of first limiting blocks 115. When the second manipulator grabs the base 91 injection-molded by the injection molding machine and places it on the first bearing platform 114, the side wall of the base 91 abuts against the side of the first limiting block 115, and the clamping structure clamps and fixes the base 91;

[0072] It should be noted that, since the bottom groove of the base 91 needs to be aligned with the positioning block 32, and after the base 91 is demoulded from the injection molding machine, the second manipulator cannot directly place the base 91 on the positioning block 32 on the support plate 3 in the loading area in this way, so a transfer component is added here;

[0073] Specifically, when the second manipulator places the base 91 on the top surface of the first supporting platform 114 (here the bottom groove of the base 91 faces upward), the base 91 is limited between the first limit block 115, and then the base 91 is clamped and fixed by adjusting the clamping structure so that it will not fall when it is subsequently flipped one hundred and eighty degrees. After the base 91 is clamped and fixed, the motor 112 is started to drive the rotating rod 113 to rotate, thereby driving the first supporting platform 114 to rotate one hundred and eighty degrees. At this time, the bottom groove of the base 91 faces downward and faces the positioning block 32 on the support plate 3 of the loading area. The clamping structure is adjusted to no longer fix the base 91, so that the base 91 slides and is located on the positioning block 32, thereby realizing automatic loading of the base 91.

[0074] like Figure 7 As shown, a fixing frame 118 and a third driving member 117 (which can be set as a cylinder here) are fixed on the top surface of the assembly table 1, and the output end of the third driving member 117 is fixedly connected to the supporting frame 111, and the supporting frame 111 is slidably arranged on the fixing frame 118;

[0075] When the first supporting platform 114 rotates 180 degrees and the bottom groove of the base 91 faces downward to the positioning block 32 on the support plate 3 in the loading area, the third driving member 117 is started to drive the support frame 111 to move closer to the assembly table 1, so that the base 91 gradually moves closer to the positioning block 32 until the positioning block 32 completely enters the bottom groove, thereby accurately positioning the base 91 to prevent the base 91 from being unable to naturally and quickly slide onto the positioning block 32, thereby ensuring its stability when it rotates on the support plate 3.

[0076] like Figure 1 and Figure 8 As shown, the casing 92 and the top plate 94 are injection molded by (the same) injection molding machine (not shown in the figure) (here, the models of the casing 92 and the top plate 94 can be opened on the same set of molds), and the fully automatic assembly production line also includes a third manipulator (not shown in the figure) and a second bearing platform 121. The top surface of the second bearing platform 121 is provided with at least one set of second limiting structures and third limiting structures. The second limiting structure includes a plurality of second limiting blocks 122, and the third limiting structure includes a plurality of second limiting rods 123. The second limiting rods 124 are provided with a plurality of second limiting blocks 125. 23 is located between the second limiting blocks 122. When the third manipulator grabs the casing 92 and the top plate 94 molded by the injection molding machine and places them on the second carrying platform 121, each top plate 94 is located in the middle of a casing 92, and the outer edge of the top plate 94 abuts against the outer wall of the second limiting rod 123, and the outer wall of the casing 92 abuts against the second limiting blocks 122, so that the first manipulator 4 can drive the first material picking assembly 54 and the second material picking assembly 55 to move to accurately grab and place the casing 92 and the top plate 94;

[0077] A rotating table 12 is provided here, and at least two second supporting platforms 121 are provided on the rotating table 12 at equal intervals. Thus, when the third manipulator grabs the injection-molded casing 92 and the top plate 94 and places them on one second supporting platform 121, the casing 92 and the top plate 94 on the other second supporting platform 121 are grabbed by the first manipulator 4 driving the first material picking assembly 54 and the second material picking assembly 55 and assembled on the base 91 respectively, which is more efficient.

[0078] like Figure 1As shown, the fully automatic assembly production line also includes a fourth manipulator and a third supporting platform 13 for supporting and placing the brush cloth 93. The third supporting platform 13 is provided with at least one set of fourth limiting structures. The fourth limiting structure includes a plurality of third limiting rods. When the fourth manipulator places the cut brush cloth 93 on the third supporting platform 13, the outer edge of the brush cloth 93 abuts against the outer wall of the third limiting rod, which facilitates the subsequent first manipulator 4 to drive the third material picking component 57 to move to accurately pick up and place the brush cloth 93.

[0079] Although 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.
