When the main parts assembled with the springs are transported to the corresponding assembly station, the mating parts need to be manually taken out, and then the springs need to be compressed to assemble the mating parts. The existing assembly method is cumbersome, time-consuming, labor-intensive, and inefficient.

[0004] To this end, we propose a device that can improve assembly efficiency. Utility Model Content

[0032] The utility model provides a spring assembling device with high efficiency.

[0033] like Figures 1 to 5 As shown, in one embodiment of the present invention, the highly efficient spring assembly device includes a loading unit and an assembly unit. The loading unit contains the assembly material to be assembled, and the output end of the loading unit is connected to the input end of the assembly unit.

[0034] like Figure 1 and 2As shown, the loading unit includes a second material loading component 100, a third material loading component (not shown in the figure) and a first assembly component 200, and the first assembly component 200 includes a second material transfer part 210, a third material transfer part (not shown in the figure) and a material conveying carrier 220, and the material conveying carrier 220 includes a third material input end, a second material input end and an assembly output end, and the third material input end, the second material input end and the assembly output end are arranged in sequence. Specifically, the second material loading component 100 and the third material loading component include a vibration plate 110 and a feeding track 120, the output end of the vibration plate 110 is connected to the input end of the feeding track 120, and a plurality of second materials and third materials to be assembled are respectively accommodated in the two vibration plates 110, and the second materials and the third materials are respectively transported forward through the feeding track 120. Furthermore, the second material transfer part 210 and the third material transfer part both include transfer robots, and the two transfer robots are used to transfer the second material and the third material, respectively.

[0035] In this embodiment, the second and third materials can be assembled into a composite material, and the composite material can be assembled with the first material. When assembling the second and third materials, the third material is first transferred by a transfer robot to the third material input terminal of the material conveying carrier 220. The second material is then transferred by the transfer robot to the second material input terminal of the material conveying carrier 220, where it is assembled with the third material to form the composite material. The composite material is then transported to the composite output terminal, where it is transferred and assembled by the assembly unit.

[0036] like Figures 1 to 5 As shown, the assembly unit includes a second assembly component 300, a conveyor assembly 400, a compression spring clamp 500, and a first material carrier 600. In this embodiment, the conveyor assembly 400 includes two conveyor rails 410 and two conveyor motors 420. The two conveyor rails 410 are arranged in parallel, and the conveyor motors 420 are arranged at the ends of the conveyor rails 410. The first material carrier 600 is arranged on the two conveyor rails 410. The conveyor motors 420 are used to drive the conveyor rails 410 to transport the first material carrier 600.

[0037] Specifically, the second assembly component 300 includes a four-axis robot 310 and a combined fixture. The combined fixture is located at the end of the four-axis robot 310. The loading unit, the four-axis robot 310, and the combined fixture are all located on the same side of the conveyor assembly 400. The compression spring fixture 500 is located on the other side of the conveyor assembly 400. Furthermore, the combined fixture includes a take-up assembly mounting base 3201 and a gripper cylinder 3202. The take-up assembly mounting base 3201 is located at the end of the four-axis robot 310. The gripper cylinder 3202 is mounted on the take-up assembly mounting base 3201. The gripper cylinder 3202 includes cylinder fingers.

[0038] During assembly, once the assembly material is delivered to the assembly output, the gripper cylinder 3202 transfers the assembly material from the assembly output to the first material carrier 600, thereby assembling the assembly material and the first material into a single unit. During the transfer of the assembly material, the gripper cylinder 3202 grips the assembly material with its gripping fingers. Driven by the four-axis robot 310, the gripper cylinder 3202 reciprocates between the assembly output of the material delivery carrier 220 and the first material carrier 600. It is worth noting that the four-axis robot 310 is a mature prior art technology and will not be described in detail in this embodiment.

[0039] like Figure 1 、 3 As shown in Figures 4 and 5, the compression spring fixture 500 includes a compression spring mounting plate 510, a first telescopic cylinder 520, a first slider 5201, a mounting block 530, a second telescopic cylinder 540, a second slider 5401, and a pressing plate 550. The number of each of the second telescopic cylinder 540, the second slider 5401, and the pressing plate 550 is two. The first material carrier 600 includes two material placement positions, and the two second telescopic cylinders 540 are respectively arranged on both sides of the mounting block 530. In addition, the mounting block 530 includes an avoidance groove 5301 located in the middle of the mounting block 530. When the two pressing plates 550 move to the first material carrier 600 at the same time, the avoidance groove 5301 can avoid the gap between the two material placement positions, thereby allowing the two second telescopic cylinders 540, the second slider 5401, and the pressing plate 550 to perform a spring compression operation on the first material in the two placement positions.

[0040] Specifically, the compression spring mounting plate 510, the first slider 5201, and the second slider 5401 are all L-shaped. The first telescopic cylinder 520 is mounted on the upper lateral side of the compression spring mounting plate 510, while the lower vertical side of the compression spring mounting plate 510 is connected to the side of the conveyor rail 410. Secondly, the output end of the first telescopic cylinder 520, the vertical side of the first slider 5201, the mounting block 530, and the two second telescopic cylinders 540 are sequentially connected, with one side of the first telescopic cylinder 520 slidingly connected to the lateral side of the first slider 5201. Thirdly, the output end of the second telescopic cylinder 540, the lateral side of the second slider 5401, and the pressure plate 550 are sequentially connected, with one side of the second telescopic cylinder 540 slidingly connected to the vertical side of the second slider 5401.

[0041] Specifically, the working principle and process of the utility model are as follows:

[0042] By providing a loading unit, a conveying assembly, a first material carrier, a four-axis robot, a combination clamp and a compression spring clamp, the degree of automation of the assembly operation can be improved, the operation is simpler, and the efficiency of spring assembly can be improved.

[0043] When assembling the composite material and the first material into a single unit, the composite material at the output end of the composite can be transferred to the first material carrier via a gripper cylinder. Before the composite material is transferred to the first material carrier, the pressure plate can be driven by the first and second telescopic cylinders to move above the first material, thereby compressing the spring. After the composite material is transferred to above the first material and the pressure plate by the gripper cylinders, the gripper cylinder can be driven downward by a four-axis robot, thereby moving the composite material above and close to the pressure plate. At this point, the first telescopic cylinder drives the pressure plate to move laterally away from the gripper cylinder, thereby transferring the spring from its compressed state to its normal state. During the spring's recovery process, the gripper cylinder can be driven further downward by the four-axis robot to compress the composite material, thus completing the assembly operation.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
