[0002] A shelf is a rack used to store goods. It provides an orderly storage space for goods. The shelf legs are an important part of the shelf structure. Its main function is to support the weight of the shelf and transfer the gravity of the shelf and the goods it carries to the ground. Its stability is directly related to the safety of the shelf during use. It can prevent the shelf from tipping over and ensure the safe storage of goods.

[0003] At present, the shelf legs will be assembled before use. To complete the assembly of the shelf legs, the various components of the shelf legs will be classified during the assembly process, and then assembled in sequence. However, the general shelf leg assembly work is completed on the assembly line. This assembly line occupies a large area and the processing positions are not concentrated. The staff improved the existing assembly line processing and designed a circular processing line. The spatial layout of the circular processing line is circular, which solves the problem of occupying area. At the same time, the flow of materials in the circular processing line is relatively flexible, which is convenient for the staff to deal with problems in time when they arise.

[0004] However, different shelf legs are suitable for different shelf structures, and the component structures of the shelf legs are different, and their plug-in installation positions are also different.

The motor device is used to drive the rotating table 12 to rotate. The rotating table 12 is used to adjust the position of the rotating mechanism 13. When the processing position needs to be adjusted, the rotating table 12 can be started, and the rotating mechanism 13 is driven to move by the rotating table 12, thereby realizing the adjustment of the assembly position. The rotating mechanism 13 is used to adjust the position of the assembly component.

[0048] See also Figure 1 A support leg assembly 7 is provided on one side of the placement assembly 1, and the specific structure of the support leg assembly 7 is as follows: See also Fig. 9The support leg assembly 7 includes a first accessory 71, a second accessory 72, a third accessory 73 and a fourth accessory 74 in sequence.

[0049] See also Figure 1 , a first assembly component 2 is arranged on the upper side of the placement component 1, and the specific structure of the first assembly component 2 is as follows: See also Figure 1-3 The first assembly component 2 includes a first feeding mechanism 21 , a first assembly mechanism 22 is disposed on one side of the first feeding mechanism 21 , the first assembly mechanism 22 includes a first rotating cylinder and a first mechanical claw, and the first mechanical claw is used to grab the first accessory 71 .

[0050] See also Figure 1 A second assembly component 3 is provided on one side of the first assembly component 2, and the specific structure of the second assembly component 3 is as follows: See also Figure 1-3 The second assembly component 3 includes a second assembly mechanism 32, and a second feeding mechanism 31 is arranged below the second assembly mechanism 32. The second feeding mechanism 31 is used to convey the second accessory 72. A placement table for placing the second accessory 72 is arranged on the top of the second feeding mechanism 31, so as to facilitate the second feeding mechanism 31 to convey the second accessory 72.

[0051] See also Figure 4 The second assembly mechanism 32 is used to grab the second accessory 72 . The specific structure of the second assembly mechanism 32 is as follows: the second assembly mechanism 32 includes a fixed plate 321 , a first cylinder 322 is arranged on the top of the fixed plate 321 , and a first sliding plate 325 is arranged at the output end of the first cylinder 322 .

[0052] See also Figure 4 A group of support columns 324 are respectively provided at the four corners of the bottom of the fixed plate 321, and the support columns 324 are fixedly connected to the fixed plate 321. The four groups of support columns 324 are slidably connected to the first sliding plate 325, and a second sliding plate 326 is provided in the middle position between the first sliding plate 325 and the fixed plate 321.

[0053] See also Figure 4 The second sliding plate 326 slides relatively with the first sliding plate 325. A second cylinder 323 is provided on one side of the second sliding plate 326. The output end of the second cylinder 323 is fixedly connected to the second sliding plate 326. An air claw 327 is provided through the second sliding plate 326. A through groove is provided through the first sliding plate 325. The through groove is convenient for the placement of the air claw 327 and the movement of the air claw 327 back and forth. The air claw 327 is used to grab the second accessory 72.

[0054] The movement process of the air gripper 327 is as follows: The up and down movement of the air gripper 327 mainly depends on the first cylinder 322. After the first cylinder 322 is started, the first cylinder 322 drives the first sliding plate 325 to move linearly along the support column 324. At this time, the second sliding plate 326 moves linearly following the first sliding plate 325, and the air gripper 327 moves linearly following the second sliding plate 326, thereby realizing the up and down movement of the air gripper 327. By setting the first cylinder 322, it is easy to adjust the position of the air gripper 327, which brings convenience to the air gripper 327 to grasp accessories.

[0055] The left and right movement of the air gripper 327 mainly depends on the second air cylinder 323. When the second air cylinder 323 is started, the second air cylinder 323 drives the second sliding plate 326 to move in a straight line along the first sliding plate 325. The air gripper 327 follows the second sliding plate 326 to move in a straight line along the first sliding plate 325, thereby realizing the forward and backward movement of the air gripper 327. The forward and backward movement of the air gripper 327 makes it easier for the air gripper 327 to reach the position of the second feeding mechanism 31, so that the air gripper 327 can grab the assembly components.

[0056] By providing the first cylinder 322 and the second cylinder 323, the up-down and forward-backward movements of the air gripper 327 are realized, which brings convenience to the air gripper 327 to grasp the assembly components and provides guarantee for the normal progress of the assembly work.

[0057] See also Figure 1 A third assembly component 4 is provided on a side of the second assembly component 3 away from the first assembly component 2. The specific structure of the third assembly component 4 is as follows: See also Figure 1-6 The third assembly component 4 includes a third assembly mechanism 42 , and a third feeding mechanism 41 is arranged below the third assembly mechanism 42 . The third feeding mechanism 41 is used to convey the third accessory 73 , and the third assembly mechanism 42 is used to grab the third accessory 73 .

[0058] See also Figure 1 A fourth assembly component 5 is provided on the opposite side of the second assembly component 3, and the specific structure of the fourth assembly component 5 is as follows: See also Figure 1-6 The fourth assembly component 5 includes a fourth assembly mechanism 52 , and a fourth feeding mechanism 51 is arranged below the fourth assembly mechanism 52 . The fourth feeding mechanism 51 is used to convey the fourth accessory 74 , and the fourth assembly mechanism 52 is used to convey the fourth accessory 74 .

[0059] The fourth assembly mechanism 52, the third assembly mechanism 42 and the second assembly mechanism 32 have the same structure, and the process of grabbing and assembling components is basically the same, which brings convenience to the normal progress of the assembly work.

[0060] See also Figure 1The first assembly component 2 is provided with a blanking component 6 on one side of the fourth assembly component 5 away from the third assembly component 4. The specific structure of the blanking component 6 is as follows: See also Figure 1-3 The unloading assembly 6 includes an unloading conveyor belt 61, which is used to transport the support leg assembly 7. A unloading mechanism 62 is provided on one side of the unloading conveyor belt 61. The unloading mechanism 62 includes a second rotating cylinder and a second mechanical claw, and the second mechanical claw is used to grab the support leg assembly 7.

[0061] The specific assembly process of the support leg assembly 7 is as follows: First, the first accessory 71, the second accessory 72, the third accessory 73, and the fourth accessory 74 are placed in the positions of the first feeding mechanism 21, the second feeding mechanism 31, the third feeding mechanism 41, and the fourth feeding mechanism 51 in sequence to complete the transportation of the assembly materials of the leg assembly 7, and then the first assembly mechanism 22 is started. The first assembly mechanism 22 grabs the first accessory 71 through the first mechanical claw and places it on the rotating mechanism 13 to complete the loading of the first accessory 71.

[0062] After the loading of the first accessory 71 is completed, the rotating table 12 is started. The rotating table 12 rotates the rotating mechanism 13 to a position relative to the second feeding mechanism 31 through the rotation function. The second assembly mechanism 32 is started, and the second assembly mechanism 32 grabs the second accessory 72 at the second feeding mechanism 31 and installs the second accessory 72 to the outside of the first accessory 71, thereby completing the assembly of the second accessory 72 and the first accessory 71.

[0063] After the assembly of the first accessory 71 and the second accessory 72 is completed, the rotating table 12 is started again, and the rotating table 12 rotates the rotating mechanism 13 to the position of the third feeding mechanism 41. The third assembly mechanism 42 is started, and the third assembly mechanism 42 grabs the third accessory 73 at the third feeding mechanism 41, and the third assembly mechanism 42 drives the third assembly mechanism 42 to install the third accessory 73 to the outside of the second accessory 72, thereby completing the assembly of the third accessory 73 and the second accessory 72.

[0064] After the assembly of the third accessory 73 and the second accessory 72 is completed, the rotating table 12 is started again to rotate the rotating mechanism 13 to the position of the fourth feeding mechanism 51, and the fourth assembly mechanism 52 is started. The fourth assembly mechanism 52 grabs the fourth accessory 74 at the fourth feeding mechanism 51, and the fourth accessory 74 is installed on the upper side of the third accessory 73 to complete the assembly of the fourth accessory 74 and the third accessory 73. At this point, the overall assembly of the support leg assembly 7 is completed. Finally, the rotating table 12 is started again to rotate the rotating mechanism 13 to the position of the unloading mechanism 62. The unloading mechanism 62 grabs the support leg assembly 7 through the second mechanical claw, and places the support leg assembly 7 on the position of the unloading conveyor belt 61 to complete the conveying and collection of the support leg assembly 7.

[0065] The problem of long processing positions in general assembly lines is solved by providing a rotating table 12. In addition, the processing positions of the rotating table 12 are relatively concentrated, which brings convenience to adjusting the assembly position. The material flow is relatively flexible, which facilitates the assembly of the support leg assembly 7.

[0066] By arranging the first assembly mechanism 22 , the second assembly mechanism 32 , the third assembly mechanism 42 and the fourth assembly mechanism 52 to cooperate with the rotating table 12 , the assembly device is further improved to facilitate the normal assembly work.

[0067] In the second embodiment, a rotating table 12 is provided to provide an assembly environment for the leg assembly 7. However, different shelf legs are suitable for different shelf structures, and the component structures of the shelf legs are different, and their plug-in installation positions are also different. The assembly device composed of the rotating table 12 is only for positioning assembly, that is, each component is placed in sequence and then assembled in sequence. If a special structure appears in the component of the shelf leg, the existing assembly device cannot be compatible with the assembly of the shelf leg with a special structure.

[0068] To this end, first analyze the accessories of the foot assembly 7 to understand the composition of the foot assembly 7. The specific structure of the foot assembly 7 is as follows: See also Figure 9-12 The second accessory 72 includes a rubber seat 721 , the inner wall of the rubber seat 721 is provided with threads, the first accessory 71 is provided inside the rubber seat 721 , and the outer side of the first accessory 71 is provided with threads, and the thread shape of the first accessory 71 is adapted to the thread shape of the rubber seat 721 .

[0069] See also Figure 9-12 A card slot 722 is provided on the outer side of the rubber seat 721, and a third accessory 73 is arranged inside the card slot 722. The third accessory 73 includes a card plate 731, and the card plate 731 is symmetrically penetrated with two groups of jacks 732. The card plate 731 is also penetrated with a through hole 733, and the through hole 733 is arranged on one side of the jack 732.

[0070] See also Figure 9-12 A fourth accessory 74 is arranged above the third accessory 73 , and the fourth accessory 74 includes an assembly seat 741 , and two groups of buckles 742 are symmetrically arranged at the bottom of the assembly seat 741 , and the shape of the buckles 742 is adapted to the shape of the socket 732 .

[0071] The assembly sequence of the support leg assembly 7 is as follows: the first accessory 71 is connected to the second accessory 72 by threads, the second accessory 72 is snap-connected to the third accessory 73, that is, the slot 722 fits with the card plate 731, and the third accessory 73 is plug-in connected to the fourth accessory 74, that is, the buckle 742 is plugged into the position of the socket 732.

[0072] Since the rotating platform 12 is rotatable, the positions of the accessories are different during the assembly of the support leg assembly 7. Therefore, the details of the rotating mechanism 13 are improved to make the rotating mechanism 13 suitable for the operation of the rotating platform 12. The specific structure of the rotating mechanism 13 is as follows: The rotating mechanism 13 includes an adjusting motor 131, which is installed at the bottom of the rotating table 12. The output end of the adjusting motor 131 passes through the rotating table 12 and is connected to a mounting plate 132. When the processing position changes, the adjusting motor 131 is started, and the position of the mounting seat 133 is adjusted by the adjusting motor 131, thereby adjusting the position of the accessories on the mounting seat 133.

[0073] A mounting seat 133 is provided on the top of the mounting plate 132. Two sets of telescopic fixing mechanisms 134 are provided on the top of the mounting seat 133. The telescopic fixing mechanism 134 includes a fixing block and a telescopic rod. The telescopic fixing mechanism 134 is used to fix the first accessory 71. When the first accessory 71 is placed on the mounting seat 133, the fixing block is pushed to the first accessory 71 through the telescopic rod, and the first accessory 71 is fixed through the fixing block.

[0074] Since the first accessory 71 is provided with a thread on the outside and the second accessory 72 is provided with a thread on the inside, the first accessory 71 and the second accessory 72 are assembled in a spiral manner. When the first accessory 71 and the second accessory 72 are assembled, the adjusting motor 131 is started, and the rotational force is provided by the adjusting motor 131. During the rotation process, the first accessory 71 gradually passes through the inside of the second accessory 72. In order to cooperate with the assembly work, the first cylinder 322 at this time drives the air claw 327 to realize downward linear motion, ensuring that the first accessory can be completely assembled into the inside of the second accessory.

[0075] The first cylinder 322 is provided to assist the assembly of the first accessory 71 and the second accessory 72 , thereby ensuring that the assembly of the first accessory 71 and the second accessory 72 proceeds normally.

[0076] However, only designing the rotating mechanism 13 cannot be fully applicable to the assembly of the support leg assembly 7. The rotating mechanism 13 will change following the rotating platform 12. In this case, the assembly work cannot be carried out normally.

[0077] See also Figure 7 To this end, a first visual detection sensor 43 is provided below the third assembly mechanism 42. The first visual detection sensor 43 is mainly used to detect the position of the telescopic fixing mechanism 134. When the third accessory 73 and the second accessory 72 are assembled, the telescopic fixing mechanism 134 and the socket 732 are relatively arranged, which facilitates the assembly of the third accessory 73 and the fourth accessory 74.

[0078] The detection process of the first visual detection sensor 43 is as follows: The detection reference point of the first visual detection sensor 43 is based on the position of the telescopic fixing mechanism 134 and the third feeding mechanism 41, that is, when the telescopic fixing mechanism 134 and the third feeding mechanism 41 are relatively arranged, the adjusting motor 131 does not need to be started again, on the contrary, when the telescopic fixing mechanism 134 and the third feeding mechanism 41 are not in a relatively arranged position, the adjusting motor 131 is started, and the adjusting motor 131 drives the mounting seat 133 to rotate until the telescopic fixing mechanism 134 and the third feeding mechanism 41 are relatively arranged.

[0079] The first visual detection sensor 43 is provided to facilitate the assembly of the leg assembly 7. When the telescopic fixing mechanism 134 and the third feeding mechanism 41 are determined, the third accessory 73 and the second accessory 72 are assembled, and the socket 732 is opposite to the telescopic fixing mechanism 134, which facilitates the insertion of the buckle 742 into the socket 732.

[0080] After the assembly of the second accessory 72 and the third accessory 73 is completed, the third accessory 73 and the fourth accessory 74 are subsequently plug-in settings, and the two sets of buckles 742 need to be plugged into the sockets 732. However, during the rotation of the turntable 12, the position of the socket 732 will change. In addition, since the second accessory 72 and the third accessory 73 are snap-connected settings, the second accessory 72 is made of rubber, and the second accessory 72 and the third accessory 73 are unsaturatedly fixed, during the rotation of the turntable 12, there will be a slight position displacement between the third accessory 73 and the second accessory 72. If the fourth accessory 74 is installed directly, there will be problems with the assembly, which will affect the use of the support leg assembly 7 in actual applications.

[0081] See also Figure 8 To this end, a second visual detection sensor 53 is provided below the fourth assembly mechanism 52 . The second visual detection sensor 53 is mainly used to detect the position of the insertion hole 732 . The position of the insertion hole 732 is arranged parallel to the fourth feeding mechanism 51 .

[0082] The detection process of the second visual detection sensor 53 is as follows: The detection reference point of the second visual detection sensor 53 is based on the parallel setting of the two groups of jacks 732 and the fourth feeding mechanism 51, that is, when the two groups of jacks 732 and the fourth feeding mechanism are parallel, the adjustment motor 131 does not need to be started again. On the contrary, if the two groups of jacks 732 and the fourth feeding mechanism 51 are not in a parallel position, the adjustment motor 131 is started, and the adjustment motor 131 drives the mounting seat 133 to rotate until the two groups of jacks 732 are relatively arranged with the fourth feeding mechanism 51.

[0083] The second visual detection sensor 53 is provided to facilitate the assembly of the leg assembly 7, so that the position of the socket 732 can be adjusted to ensure that the buckle 742 is plugged into the socket 732 , thereby completing the assembly of the fourth accessory 74 and the third accessory 73 .
