[0001] The utility model relates to the technical field of spring material separation and assembly, in particular to an automatic assembly device for an automobile seat control valve spring. Background Art

[0002] The size of the automobile seat control valve spring is relatively small, generally with an outer diameter ≤ 5 mm, a wire diameter ≤ 1 mm, a length ≤ 25 mm, and a pitch ≤ 2 mm. Due to cost issues, most manufacturers choose to receive the materials in bag packaging, resulting in many springs being wound together when receiving the materials. Since the springs are small, manual separation will cause changes in the spring performance and unstable quality, and at the same time, a large amount of labor cost is required.

[0003] At present, some manufacturers choose to transport and supply the springs in PA66 nylon pipes in order to ensure that the springs are not wound. Although this avoids the winding of the springs, it increases the cost of spring packaging and transportation, and even the cost of the PA66 nylon pipe itself far exceeds the cost of the spring material.

A spring detection camera 22 is provided on one side of the product 21.

[0022] In a further implementation manner, referring to Figure 1And Figure 3 The vibrating bowl feeder 3 for springs is provided with two layers. The upper layer is connected to the feed inlet of the spring separator 4 and the spring bin 2, and the lower layer is connected to the discharge outlet of the spring separator 4 and the linear vibrating track 6. A first spring separation cylinder 5 is provided on the linear vibrating track 6. The first spring separation cylinder 5 is arranged outside the end of the linear vibrating track 6. The first spring separation cylinder 5 includes a first blocking cylinder 27 and a first releasing cylinder 28. A blocking pin 25 is provided on the first blocking cylinder 27, and a releasing pin 26 is provided on the first releasing cylinder 28. The distance between the releasing pin 26 and the blocking pin 25 is greater than the length of the spring. The releasing pin 26 and the blocking pin 25 can extend into the linear vibrating track 6 and be inserted into the gap between the springs. A spring separation cylinder bracket 8 is connected to the first spring separation cylinder 5. The spring separation cylinder bracket 8 is connected to the bracket base 1. A vibration controller 9 connected to the spring separator 4 and the vibrating bowl feeder 3 for springs is provided on the bracket base 1.

[0023] In a further embodiment, referring to Figure 2 And Figure 3 A second spring separation cylinder 14 is provided on the spring receiving pipe 13. The second spring separation cylinder 14 includes a second blocking cylinder 23 and a second releasing cylinder 24. A blocking pin 25 is provided on the second blocking cylinder 23, and a releasing pin 26 is provided on the second releasing cylinder 24. The distance between the releasing pin 26 and the blocking pin 25 is greater than the length of the spring. The releasing pin 26 and the blocking pin 25 can extend into the spring receiving pipe 13 and be inserted into the gap between the springs. A limit sensor is provided between the second spring separation cylinder 14 and the spring installation assembly. The limit sensor includes an upper spring limit sensor 15 and a lower spring limit sensor 16. The upper spring limit sensor 15 is close to the second spring separation cylinder 14, and the lower spring limit sensor 16 is close to the spring installation assembly;

[0024] The spring installation assembly includes a spring installation blocking cylinder 17, a spring installation releasing cylinder 18, and a spring installation air blowing device 19. The spring installation air blowing device 19 is located on both sides of the end of the spring receiving pipe 13 and is perpendicular to the incoming material direction of the spring receiving pipe 13. Both the spring installation blocking cylinder 17 and the spring installation releasing cylinder 18 are arranged outside the end of the spring receiving pipe 13 and are located inside the spring installation air blowing device 19. A blocking pin 25 and a releasing pin 26 are respectively provided on the spring installation blocking cylinder 17 and the spring installation releasing cylinder 18. The distance between the releasing pin 26 and the blocking pin 25 is greater than the length of the spring. The releasing pin 26 and the blocking pin 25 can extend into the spring receiving pipe 13 and be inserted into the gap between the springs.

[0025] When the utility model is in use, raw material springs are poured into the spring bin 2. The springs in the spring bin 2 are supplied to the spring vibrating bowl 3. The spring vibrating bowl 3 vibrates and orderly conveys the springs to the spring separator 4. Through centrifugal action, the spring separator 4 makes the springs vibrate and collide against the barrel wall, and the springs wound together are separated during the collision process. Then, the springs are conveyed to the lower layer of the spring vibrating bowl 3, and the spring vibrating bowl 3 orderly conveys the springs to the linear vibrating track 6. The first spring separating cylinder 5 on the linear vibrating track 6 separates the springs one by one. The separated springs enter the spring blowing pipe 7 and are blown to the spring installation mechanism by high-pressure air blowing.

[0026] When the springs enter the spring receiving pipe 13, when there are too many springs in the spring receiving pipe 13, their own weight will cause the springs to be compressed by different lengths, resulting in uncontrollable springs. Therefore, when both the upper spring limit sensor 15 and the lower spring limit sensor 16 can detect spring signals, it means there are too many springs, and the second spring separating cylinder 14 will extend into the spring receiving pipe 13 to prevent the springs from moving forward. When there is a shortage of materials in the spring receiving pipe 13, the second spring separating cylinder 14 will work to supplement the springs in the pipeline.

[0027] When the springs are conveyed to the end of the spring receiving pipe 13, they are blocked by the spring installation blocking cylinder 17 and the spring installation releasing cylinder 18. Then, the spring installation cylinder 11 extends above the product 21, and the spring installation releasing cylinder 18 retracts. The first spring is released, and at the same time, the spring installation blowing devices 19 on the left and right sides blow air simultaneously to assist the spring in falling, so that the spring remains balanced left and right during the falling process. At this time, the spring installation blocking cylinder 17 still extends to block the second spring, which will not affect the installation of the first spring. After the spring is installed in place, the spring detection camera 22 is used to detect the spring quality and installation position to ensure the stability of the product quality.

[0028] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not restrictive. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
