[0002] As shown in the Figure 1 accompanying drawings, there is a prior product called a ring screw, which includes a ring body and a bolt threadedly connected to the ring body. Most of the existing assembling processes are manual or semi-automatic. If manual, a worker holds the ring body with one hand and screws the bolt into the ring body with the other hand. In this way, the labor cost is high and the assembling efficiency is low. If semi-automatic, the worker places the ring body under the screwing machine and positions it, and then operates the screwing machine to send the bolt above the ring body and screw it into the ring body. Although the assembling efficiency is improved to a certain extent, there are still defects. First, there are safety hazards, and workers are easily injured due to improper operation. Second, if the ring body is not placed in place, it is easy to cause damage to the ring body, the bolt or the screwing machine. Summary of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide an automatic assembling machine for ring screws with high assembling efficiency, accurate positioning and high safety.

[0005] Two assembling grooves which are parallel to each other and respectively correspond to the output shafts of the two pushing cylinders and a common groove located between the two assembling grooves are formed on the assembling seat. The output shafts of the two screwing machines respectively face the two assembling grooves. The two material channels are both parallel to the assembling grooves, and one ends of the two material channels are both connected to the common groove;

[0006] Both of the two material dividing components include a material dividing cylinder positioned on the workbench and a material dividing block positioned on the output shaft of the material dividing cylinder. The two material dividing cylinders are respectively located on both sides of the assembling seat and are arranged facing each other. Both of the two material dividing blocks penetrate through the assembling groove along the width direction of the assembling groove and enter the common groove. Material dividing grooves for receiving the ring bodies are formed on both of the two material dividing blocks. The ring bodies in the material dividing grooves are transported to the assembling groove by the material dividing cylinder and the pushing cylinder in sequence through the two material channels respectively. The feeding component transports the bolts to the lower part of the output end of the screwing machine so that the screwing machine can screw the bolts into the ring bodies in the assembling groove.

[0007] As a further improvement of the present utility model, fixing blocks are fixedly connected to the outer walls of the two assembly seats respectively facing the two material distribution cylinders. Spring groups are provided between the two fixing blocks and the outer walls of the corresponding assembly seats. One ends of the two spring groups are fixedly connected to the corresponding fixing blocks and the other ends are fixedly connected with clamping blocks. Both clamping blocks penetrate through the groove walls on one side of the corresponding assembly grooves, and the clamping blocks press the ring bodies located in the assembly grooves to fix the positions of the ring bodies entering the assembly grooves.

[0008] As a further improvement of the present utility model, both clamping blocks are provided with inclined cutting surfaces adjacent to the corresponding material pushing cylinders and capable of sliding with the edges of the ring bodies.

[0011] As a further improvement of the present utility model, a limiting member for preventing the ring bodies from slipping out of the material distribution grooves is arranged in the common groove.

[0012] As a further improvement of the present utility model, two sensors respectively corresponding to the two material channels are arranged on the limiting member.

[0013] As a further improvement of the present utility model, the feeding assembly includes a feeding seat fixedly connected to the workbench, two switching cylinders both positioned on one side of the feeding seat, two switching blocks respectively positioned on the output shafts of the two switching cylinders, a feeding block fixedly connected to the feeding seat and located above the two switching blocks, two material nozzles respectively positioned on the two screwdrivers and capable of being penetrated by the output ends of the corresponding screwdrivers, and two feeding pipes respectively connecting the two material nozzles with the feeding seat.

Both switching blocks are provided with material distribution holes capable of being communicated with the blanking holes. The feeding block is provided with two feeding holes respectively communicated with the two material distribution holes. The switching cylinders drive the switching blocks to move linearly back and forth so that the material distribution holes are switched back and forth between the blanking holes and the feeding holes.

[0014] The beneficial effects of the present utility model: The two material channels respectively supply materials to the two material distribution blocks, so that the material distribution cylinders and the material pushing cylinders successively transport the ring bodies in the material distribution grooves to the assembly grooves.

Detailed implementation mode

[0022] The present utility model will be further described in detail below with reference to the drawings and embodiments. The same components are denoted by the same reference numerals.

[0023] Refer to Figures 1 to 6 As shown, a ring screw automatic assembly machine of this embodiment includes a workbench 1, an assembly seat 2, two material channels 3, two material distribution components 4, two pushing cylinders 5, two screw machines 6 and a loading component 7;

[0024] The assembly base 2 is fixedly connected to the workbench 1. The assembly base 2 is provided with two symmetrically arranged assembly grooves 21 and a common groove 22 located between the two assembly grooves 21. One end of each of the two material channels 3 is connected to the common groove 22 and is respectively located on one side of the corresponding assembly groove 21. A linear vibrator fixed relative to the workbench 1 is fixedly connected below the two material channels 3, and the other ends of the two material channels 3 can be externally connected to vibrating bowls containing ring bodies. Two pushing cylinders 5 are respectively positioned on one side of the two material channels 3, and the output shafts of the two pushing cylinders 5 are respectively facing the two assembly grooves 21. The two screwdrivers 6 can be respectively located above the two assembly grooves 21 through brackets positioned on the workbench 1, and the output shafts of the two screwdrivers 6 are respectively facing the two assembly grooves 21;

[0025] Each of the two material distribution components 4 includes a material distribution cylinder 41 and a material distribution block 42. The two material distribution blocks 42 are both provided with material distribution grooves 43 for receiving ring bodies. The two material distribution cylinders 41 are respectively located on both sides of the assembly base 2 and are arranged facing each other. The two material distribution blocks 42 are respectively positioned on the output shafts of the two material distribution cylinders 41. The two material distribution blocks 42 both penetrate through the assembly groove 21 along the width direction of the adjacent assembly groove 21 and partially enter the common groove 22. A limiting member 27 for preventing the ring body from slipping out of the material distribution groove 43 is arranged in the common groove 22. The design of the limiting member 27 can avoid the phenomenon that the ring body moves excessively and slips out of the material distribution groove 43 or the ring body cannot enter the assembly groove 21;

[0026] The feeding component 7 includes a feeding base 71, two switching cylinders 72, two switching blocks 73, a feeding block 74, two material nozzles 75 and two feeding pipes 76. The feeding base 71 is processed with two switching grooves for the two switching blocks 73 to linearly move respectively. The bottom of each of the two switching grooves is provided with a blanking hole 77. Each of the two switching blocks 73 is provided with a material distribution hole 78. The feeding block 74 is provided with two feeding holes 79 distributed along the length direction of the feeding block 74. The feeding base 71 is positioned on a bracket of the workbench 1 and the height of the feeding base 71 is higher than the height of the screwdriver 6. One end of each of the two feeding pipes 76 is positioned at the bottom surface of the feeding base 71 and is respectively connected to the two blanking holes 77. The inner cavity shapes of the two material nozzles 75 are approximately Y-shaped. The two material nozzles 75 are respectively positioned on the frames of the two screwdrivers 6 and are respectively located above the two assembly grooves 21. The output shafts of the two screwdrivers 6 can extend into the inner cavities of the two material nozzles 75. The other ends of the two feeding pipes 76 are respectively communicated with the inner cavities of the two material nozzles 75. The two switching blocks 73 are respectively fixedly connected to the output shafts of the two switching cylinders 72 and the two switching blocks 73 are respectively placed in the two switching grooves. The two switching cylinders 72 are both positioned on one side of the feeding base 71. The feeding block 74 is positioned above the feeding base 71 and the two feeding holes 79 are respectively located above the two switching grooves. The feeding block 74 can be externally connected to two feeding pipes respectively communicated with the two feeding holes 79 and the other ends of the two feeding pipes are externally connected to vibrating bowls containing bolts;

[0027] In the initial state, the two material distribution grooves 43 are both located in the common groove 22 and are respectively connected to the two material channels 3. The two material distribution holes 78 are respectively connected to the two feeding holes 79, and the two material distribution holes 78 are both offset from the corresponding blanking holes 77. The assembly steps are as follows in sequence. The first step: The ring body moves along the material channel 3 to the material distribution groove 43 through the vibrating disk and the linear vibrator in sequence. The ring body touches against the limiting member 27. The bolt passes through the feeding hole 79 and enters the material distribution hole 78 through the conveying of the vibrating disk and the material pipe in sequence. The second step: The two material distribution cylinders 41 drive the corresponding material distribution blocks 42 to move outward from the assembly seat 2 until the two material distribution grooves 43 are respectively connected to the two assembly grooves 21 and the material distribution blocks 42 block one end of the material channel 3, and the two material distribution cylinders 41 both stop operating. The third step: The two pushing cylinders 5 push the ring bodies in the two material distribution grooves 43 into the corresponding assembly grooves 21 respectively, and the ring bodies are located directly below the material nozzles 75. The fourth step: The two switching cylinders 72 drive the corresponding switching blocks 73 to move linearly until the two material distribution holes 78 are respectively connected to the two blanking holes 77 and the two switching blocks 73 respectively block the orifices of the two feeding holes 79. The two bolts move along the corresponding material conveying pipes 76 to the corresponding material nozzles 75 respectively. One ends of the two bolts respectively correspond to the threaded holes of the two ring bodies and the two bolts are respectively located directly below the output shafts of the two screwdrivers 6. The fifth step: The output shafts of the two screwdrivers 6 both move downward and drive the corresponding bolts to rotate. The two bolts are respectively screwed into the two ring bodies until the bolts are screwed in place, and the two screwdrivers 6 reset. At the same time, the material distribution blocks 42 and the switching blocks 73 both return to the initial state. Repeat the above five steps, and multiple ring bodies enter the assembly groove 21 one by one and are equipped with bolts. As the number of products in the assembly groove 21 increases, the ring body assembled first will be pushed out of the assembly groove 21 by the ring body assembled later and be collected.

[0028] Such a design realizes full-automatic assembly compared with the prior art, thereby improving the assembly efficiency; there is less manual intervention throughout the process, thereby improving the safety.

[0029] As a specific embodiment of the improvement, since the pushing cylinder 5 pushes the ring body into the assembly groove 21, the ring body has inertia and moves too far, which will cause the phenomenon that the bolt cannot be smoothly screwed into the ring body. To solve the above problem, refer to Figure 5 and Figure 6As shown, on the outer walls of the assembly base 2 facing the two material distribution cylinders 41 respectively, there are fixed blocks 23 fixedly connected. There is a gap between the fixed blocks 23 and the outer wall of the corresponding assembly base 2. Spring groups 24 are arranged between the two fixed blocks 23 and the outer wall of the corresponding assembly base 2. One end of each of the two spring groups 24 is fixedly connected to the corresponding fixed block 23 and the other end is fixedly connected to a clamping block 25. The two clamping blocks 25 penetrate through the groove wall on one side of the corresponding assembly groove 21. The two clamping blocks 25 are provided with inclined surfaces 26 adjacent to the corresponding material pushing cylinder 5 and capable of sliding with the edge of the ring body. In the initial state, the end of the clamping block 25 processed with the inclined surface 26 extends into the assembly groove 21. During the assembly process, as the ring body is gradually pushed into the assembly groove 21 by the material pushing cylinder 5, the edge of the ring body slides relative to the inclined surface 26, and the clamping block 25 gradually moves out of the assembly groove 21. The spring group 24 is compressed to generate elastic potential energy. After the ring body separates from the inclined surface 26, it will slide relative to the end face of the clamping block 25. The clamping block 25 generates a thrust on the ring body through the elastic force generated by the spring group 24, so as to jointly apply a clamping force to the ring body with the groove wall opposite to the assembly groove 21. In this way, when the material pushing cylinder 5 stops pushing the ring body, the ring body can immediately stop moving. Such a design can make up for the defects of the prior art, ensure the position of the ring body in the assembly groove 21 is fixed, and facilitate the bolt to be smoothly screwed into the ring body.

[0030] As a specific implementation of the improvement, referring to Figure 5 shown, the lengths of the two material distribution blocks 42 in the width direction of the assembly groove 21 are designed to ensure that when the two material distribution blocks 42 are in contact with each other, the two material distribution grooves 43 respectively correspond to the two material channels 3, and the ring body can smoothly enter the material distribution grooves 43 through the material channels 3. Such a design can eliminate the limit switch compared with the design of adding a limit switch in the common groove 22 to control the movement of the material distribution block 42, reducing the complexity and cost of the equipment.

[0031] As a specific implementation of the improvement, referring to Figure 5 shown, on the opposite end faces of the two material distribution blocks 42, there are respectively arranged an insertion block 44 and a slot 45 that can be inserted into each other. The design of the insertion block 44 and the slot 45 being inserted into each other can prevent the two material distribution blocks 42 from bending or shifting up and down relative to the horizontal plane, so as to ensure that the height of the bottom of the material distribution groove 43 is less than or equal to the height of the bottom of the common groove 22, which is beneficial for the ring body to smoothly enter the material distribution groove 43.

[0032] As a specific implementation of the improvement, referring to Figure 4 and Figure 5As shown in the figure, two sensors 28 corresponding to the two material channels 3 are arranged on the limiting member 27. The sensors 28 can adopt touch switches. When the ring body enters the material distribution groove 43 and touches the sensors 28, the sensors 28 feed back signals to the controller, and the controller sends signals to the material distribution cylinder 41, so that driven by the material distribution cylinder 41, the ring body can enter the assembly groove 21 in time. Such a design can further improve the linkage and accuracy of the assembly steps and indirectly improve the assembly efficiency.

[0033] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
