[0004] In daily production, cylindrical parts wrapped with rubber sleeves are often used (the cylindrical parts wrapped with rubber sleeves can be metal round bars, round wooden bars, etc.). When assembling such products, due to the large friction resistance of the rubber sleeve itself, an existing method is to apply lubricating oil on the sleeved cylindrical parts in advance, and then manually put the rubber sleeve on the cylindrical parts. This method is the most traditional operation method, which relies on manual labor and is inefficient. In addition, excessive application of lubricating oil will make the rubber sleeve unreliable in the later assembly on the cylindrical parts. Another method is to use an opening mechanism to open the rubber sleeve, and then extend the cylindrical part into the opened rubber sleeve. However, the loading and unloading of the existing opening mechanism depends on manual labor, and the degree of automation of sorting is low. Summary of the invention:

[0033] The present invention will be further described below in conjunction with the accompanying drawings.

[0034] like Figure 1 and Figure 2The present invention discloses an automatic assembly device for inserting a cylindrical part into a rubber sleeve, comprising a cylindrical part feeding unit 1, a rubber sleeve conveying unit 2, a receiving platform 3, a spreading claw 4, a pressing seat 5, a top plate 6 and a conveying belt 7. The cylindrical part feeding unit 1, the rubber sleeve conveying unit 2, the top plate 6 and the conveying belt 7 are all arranged on one side of the receiving platform 3, the spreading claw 4 and the pressing seat 5 are all arranged above the receiving platform 3, a V-shaped groove is arranged on the receiving platform 3, the rubber sleeve is fed into the V-shaped groove of the receiving platform 3, the spreading claw 4 extends into the rubber sleeve and spreads the rubber sleeve, and the cylindrical part 400 is inserted into the spread rubber sleeve 410. The pressing seat 5 presses down and presses the rubber sleeve with the cylindrical part inserted into the V-shaped groove of the receiving platform 3, and then the spreading claw 4 is withdrawn from the rubber sleeve. The top plate rises to eject the rubber sleeve from the V-shaped groove of the receiving platform 3 and send it to the conveyor belt, and the next rubber sleeve is sent to the receiving platform 3, and the same process is repeated. The length of the rubber sleeve applicable to the present invention does not exceed 50cm.

[0035] like Figure 3 The cylindrical part feeding unit 1 of the present invention comprises a storage bin 11, a feeding plate 12, a material removing claw 13, a cylindrical part feeding trough 14, a cylindrical part feeding block 15 and a first feeding cylinder. The storage bin 11 is a rectangular bin structure, the bottom surface of the storage bin 11 is an inclined surface, the feeding plate 12 is vertically inserted into the storage bin 11, and the feeding plate 12 is located at the bottom end of the inclined side of the bottom surface, and the feeding plate 12 is in contact with the inner wall surface of the left side of the storage bin 11. The material plate 12 is driven by a cylinder and moves up and down along the inner wall surface of the left side of the storage bin 11. The cylindrical feeding trough 14 is arranged on the outside of the storage bin 11. The groove cross-section of the cylindrical feeding trough 14 is V-shaped. The bottom end surface of the cylindrical feeding block 15 is V-shaped. The bottom end surface of the cylindrical feeding block 15 is placed in the cylindrical feeding trough 14. The first feeding cylinder drives the cylindrical feeding block 15 to slide in the cylindrical feeding trough 14.

[0036] like Figure 4 A material-dispensing shaft 16 is rotatably connected above the storage bin 11 , and the material-dispensing shaft 16 is rotated by a cylinder drive, and a plurality of material-dispensing claws 13 are evenly distributed on the material-dispensing shaft 16 , and an inclined material guide block 17 is provided between the feed plate 12 and the cylindrical feed trough 14 .

[0037] The feeding plate 12 lifts up the cylindrical member 400 in the storage bin 11, and the material-discharging shaft 16 rotates, and the material-discharging claw 13 removes the cylindrical member 400 at the top of the feeding plate 12 and rolls it into the cylindrical member feeding trough 14 through the material guide block 17. In order to facilitate the material-discharging claw 13 to act on the cylindrical member 400 on the feeding plate 12, a plurality of spaced support blocks 121 are provided at the top of the feeding plate 12, and the material-discharging claw 13 and the support blocks 121 are staggered with each other. When the material-discharging shaft 16 drives the material-discharging claw 13 to rotate, the material-discharging claw 13 enters between the adjacent support blocks 121 and finally discharging the cylindrical member 400 placed on the support block 121 onto the material guide block 17.

[0038] When conveying the cylindrical members 400, the cylindrical members 400 are placed side by side in the storage bin 11. Since the bottom surface of the storage bin 11 is a downwardly inclined inclined structure, the cylindrical members 400 roll downward in sequence. In order to better receive the cylindrical members 400, a V-shaped groove is also provided at the top of the support block 121. In the initial state, the top surface of the V-shaped groove in the support block 121 is flush with the bottom end surface of the storage bin 11, so that the cylindrical members 400 can roll into the V-shaped groove of the support block 121.

[0039] In order to better ensure that the cylindrical parts 400 enter the V-shaped grooves of the support blocks 121 in a parallel manner in sequence, a discharge plate 111 is provided in the storage bin 11. The discharge plate 111 is arranged vertically, and the bottom end of the discharge plate 111 is about 1 cm away from the ground of the storage bin 11, which is greater than the diameter of the cylindrical parts 400. The distance between the discharge plate 111 and the inner wall of the left side of the storage bin 11 is 6 times the diameter of the cylindrical parts 400, that is, 6 cylindrical parts 400 can be placed side by side between the discharge plate 111 and the left side of the storage bin 11. Through the setting of the discharge plate 111, it can be effectively ensured that the cylindrical parts 400 in the storage bin 11 enter side by side when approaching the feeding plate 12, thereby avoiding the cylindrical parts 400 from being stacked.

[0040] like Figure 5 The rubber sleeve conveying unit 2 in the present invention includes a chain sprocket conveying mechanism 21, a conveying seat 22 and a first material guide plate 23. A plurality of conveying seats 22 are fixed on the chain sprocket conveying mechanism 21 to form a plurality of annular conveying units 20 that are arranged at intervals and parallel to each other. A first material guide plate 23 is arranged between adjacent annular conveying units 20, and the first material guide plate 23 is placed at the end of the chain sprocket conveying mechanism 21. The first material guide plate 23 is arranged to be tilted downward, and the bottom end of the first material guide plate 23 is placed on the upper end surface of the material receiving table 3.

[0041] A V-shaped groove is set on each conveying seat 22. When in use, each rubber sleeve 410 is placed in the V-shaped groove of the conveying seat 22 at the same position in all the annular conveying units 20, and the chain sprocket conveying mechanism 21 rotates to realize the conveyance of the rubber sleeve 410. When the rubber sleeve 410 is conveyed to the end of the chain sprocket conveying mechanism 21, the conveying seat 22 flips over. At this time, the rubber sleeve 410 will roll onto the first guide plate 23. Since the first guide plate 23 is arranged to be tilted downward, the rubber sleeve 410 continues to roll on the first guide plate 23 toward the direction of the material receiving table 3, and finally rolls into the V-shaped groove on the top surface of the material receiving table 3.

[0042] The chain sprocket conveying mechanism 21 in the rubber sleeve conveying unit 2 continues to be driven by the stepper motor, that is, the stepper motor delivers the rubber sleeves 410 one by one to the material receiving table 3 according to a certain beat. After the rubber sleeve 410 is assembled with the cylindrical part 400 and leaves the material receiving table 3, the stepper motor drives and conveys the next rubber sleeve 410 to the material receiving table 3.

[0043] In the process of the rubber sleeve 410 rolling downward on the first guide plate 23, in order to better guide the rubber sleeve 410 and prevent the rubber sleeve 410 from tilting during the rolling process (that is, to ensure that the rolling rubber sleeve 410 is always parallel to the rubber sleeve 410 on the chain sprocket conveying mechanism 21), the present invention provides a guard edge 231 on each of the two outermost first guide plates 23, and designs the distance between the two guard edges 231 to ensure that the distance between the two guard edges 231 is greater than the length of the rubber sleeve 410 by 2-3 cm.

[0044] like Figure 6 The material receiving platform 3 in the present invention includes a plurality of material receiving columns 31, all of which are arranged at intervals on one side of the chain sprocket conveying mechanism 21, the bottom end of the first material guide plate 23 is supported on the upper end surface of the material receiving column 31, and a V-shaped groove is provided at the top of each material receiving column 31.

[0045] The present invention divides all the material receiving columns 31 into two groups, wherein the number of material receiving columns 31 in one group is 1, and the remaining material receiving columns 31 form another group. When arranging, all the material receiving columns 31 in the group with the largest number of material receiving columns 31 are placed between the two retaining edges 231, such as Figure 6 The dotted box a part in .

[0046] The press seat 5 in the present invention includes a plurality of first press blocks 51 and a second press block 52. The first press blocks 51 and the second press blocks 52 are fixed on the same mounting plate 53. The mounting plate 53 is driven by a cylinder to achieve up and down movement. The sum of the number of the first press blocks 51 and the second press blocks 52 is equal to the number of the material receiving columns 31. The first press blocks 51 and the second press blocks 52 are arranged directly above a material receiving column 31, and ensure that the group of material receiving columns 31 with the number of 1 is placed below the second press block 52, and ensure that the second press block 52 is placed at the position closest to the opening claw 4, such as Figure 6 The dotted box b part in .

[0047] Combination Figure 7 After the rubber sleeve 410 rolls down to the material-bearing column 31, due to the restriction of the two retaining edges 231, the rubber sleeve 410 is supported on all the material-bearing columns 31 in the dotted frame a ( Figure 7 Then, the claws are inserted into the rubber sleeve 410 and the rubber sleeve 410 is opened ( Figure 7d in the figure), after the rubber sleeve 410 is fully opened, the cylindrical member 400 is inserted into the rubber sleeve 410 ( Figure 7 e in Figure ).

[0048] Recombination Figure 8 When the claw needs to be pulled out, the first pressing block 51 and the second pressing block 52 are pressed down at the same time, and the first pressing block 51 presses the rubber sleeve 410 against the cylindrical member ( Figure 8 f), since a separate set of material receiving columns 31 and a second pressing block 52 are placed outside the rubber sleeve 410 ( Figure 8 (g in the figure), when the opening claw 4 is pulled out, the first pressing block 51 plays a role in pressing the rubber sleeve 410 to prevent the rubber sleeve from moving with the opening claw when the opening claw 4 is pulled out. The second pressing block 52 blocks the rubber sleeve 410 for axial positioning, further preventing the rubber sleeve from axially moving when the opening claw is pulled out.

[0049] After the opening claws are pulled out, the top plate 6 rises and pushes out the cylindrical member wrapped with the rubber sleeve on the material receiving column 31.

[0050] The top plate 6 of the present invention is provided with two pieces, which are arranged between the material receiving columns 31 in the dotted frame a, as shown in FIG. Fig. 9 The top surface of the top plate 6 is a sloped structure. When the rubber sleeve is ejected, the slope plays a guiding role, making it convenient for the rubber sleeve to be removed from the material bearing column 31. The top plate 6 is driven by the cylinder to move in the vertical direction.

[0051] A second guide plate 32 is provided between the material receiving platform 3 and the conveyor belt 7. A retaining edge is also provided on the outermost second guide plate 32 to prevent the rubber sleeve with the cylindrical member from being displaced during the rolling process. Figure 5 The second guide plate 32 is only briefly shown in the figure, and the corresponding ribs are not shown). Ribs are also provided on both sides of the conveying direction of the conveyor belt 7, and a feed port 71 is provided on one of the ribs, and the bottom end of the second guide plate 32 extends into the feed port. Finally, the assembled rubber sleeve rolls onto the conveyor belt 7 and is transported away by the conveyor belt 7.

[0052] like Fig.10The spreading claw 4 in the present invention is installed on a three-dimensional driving platform 500 that can move in three directions of XYZ (the three-dimensional platform is composed of an electric slider, which is an existing conventional structure, so the present invention does not repeat the driving platform). The specific structure of the spreading claw 4 is: including a claw rod 41, a piston 42, a guide block 43, a guide rod 44, a spring 45, a sleeve 46 and a piston cylinder. The piston 42 is slidably connected in the sleeve 46. The piston 42 includes a sliding part 421 and a driving part 422. The piston cylinder is fixedly connected to the sleeve 46. The cylinder shaft of the piston cylinder is connected to the sliding part 421. The piston cylinder drives the piston 42 to slide along the axial direction of the sleeve 46. A driving cone 420 is provided on the piston 42. Four claw rods 41 are inserted into the sleeve 46 along the axial direction of the sleeve 46, and the four claw rods 41 are evenly arranged along the circumferential direction of the sleeve 46. Each claw rod 41 is provided with a bending portion 411 adapted to the taper of the driving cone surface 420, and a guide block 43 and a guide rod 44 are fixed on each claw rod 41. The guide block 43 and the guide rod 44 are plugged on the sleeve 46 along the radial direction of the sleeve 46, and the spring 45 is sleeved on the guide rod 44. The two ends of the spring 45 respectively abut against the inner wall of the guide rod 44 and the sleeve 46. The piston 42 moves to the left and drives the four claw rods 41 to expand radially. The piston 42 moves to the right, and under the action of the spring 45, the four claw rods 41 are reset.

[0053] When in use, the three-dimensional driving platform 500 drives the opening claws 4 to be placed on the rear side of the material receiving platform 3. When the rubber sleeve needs to be opened, the three-dimensional driving platform 500 drives the claw rods 41 to extend into the rubber sleeve, and then the piston cylinder drives the four claw rods 41 to open and realize the opening of the rubber sleeve.

[0054] Since the claw rod 41 is a slender rod, in order to ensure that the claw rod 41 has sufficient strength and is not easily deformed, the claw rod 41 is made of tungsten steel. The cross section of the claw rod 41 is circular, which can reduce the contact area between the rubber sleeve and the cylindrical member.

[0055] like Fig.11 When the first pressing block 51 presses the rubber sleeve and the claw rod 41 is pulled out, in order to better make the first pressing block 51 press against the rubber sleeve, two symmetrically arranged pressing teeth 511 are provided on the bottom end surface of the first pressing block 51, and an avoidance groove 512 is provided between the two pressing teeth 511 ( Fig.11 h in the figure). When the claw rod 41 is inserted into the rubber sleeve, the insertion position of the claw rod 41 is staggered with the pressing teeth 511, and one of the claw rods 41 is ensured to be placed directly below the avoidance groove 512. After the first pressing block 51 presses down the rubber sleeve in the expanded state, the rubber sleeve is deformed and abuts against the cylindrical member in the middle, and one of the claw rods 41 is just placed in the avoidance groove 512. After the first pressing block 51 is pressed down, all the claw rods 41 are effectively avoided, preventing the claw rods 41 from being pressed and difficult to be pulled out.

[0056] Similarly, two symmetrically arranged limiting protrusions 521 are provided on the bottom end surface of the second pressing block 52, and an avoidance groove ( Fig.11 The avoidance groove here is to facilitate the extraction of the claw rod 41. The two limiting protrusions 521 are used to block the rubber sleeve and the cylindrical member, so that the claw rod 41 can be extracted to drive the rubber sleeve and the cylindrical member to move axially together.

[0057] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
