Embodiment 1

[0044] Such as figure 1 , Figure 5 As shown, a pick-up device for an optical fiber preform 4 used in the pickling process according to the present invention includes a suction cup 3, a nozzle 2, and a load-bearing frame 1. The pick-up surface of the load-bearing frame 1 is a semi-cylindrical arc surface, so The suction cups 3 and nozzles 2 are evenly distributed in the axial direction of the semi-cylindrical arc surface; in the radial direction of the semi-cylindrical arc surface, multiple groups of the suction cups 3 are arranged in a fan shape.

[0045] There are a series of suction cups 3 arranged in a fan shape on the pick-up device of the present invention. The larger the size of the preform rod 4, the more suction cups 3 participate in the work on the device, which can ensure that sufficient suction can be provided for preform rods 4 of various specifications. Suitable for preforms of various sizes4.

[0046] Such as Figure 6 , Figure 8 As shown, along the axial d...

Embodiment 2

[0059] The above-mentioned embodiment 1 is a device embodiment, and this embodiment 2 is a method embodiment. This embodiment and the above-mentioned embodiment 1 belong to the same technical concept. Please refer to the above-mentioned embodiment 1 for details not described in detail in this embodiment.

[0060] A pick-up method using the pick-up device for the optical fiber preform 4 described in Embodiment 1,

[0061] Carry the preform 4 from the rack to the pickling machine for pickling:

[0062] Step S1: The pick-up device moves above the preform 4, and opens the nozzle 2 to blow off the dust and debris on the surface of the preform 4;

[0063] Step S2: Close the nozzle 2, drop the pick-up device to the position of the preform 4, open the suction cup 3, and suck the preform 4 tightly;

[0064] Step S3: The pick-up device lifts the preform 4 and transports it to the pickling tank support, the suction cup 3 is closed, and the pick-up device moves away after the preform 4 i...

Embodiment 3

[0066] The difference between this embodiment and the above-mentioned embodiment 2 is that in embodiment 2, the preform 4 is transported from the rack to the pickling machine for pickling, while in this embodiment, the preform 4 is picked up from the pickling machine after pickling. Pickup method for transfer to storage point in pickling machine.

[0067] A pick-up method using the above-mentioned pick-up device for the optical fiber preform 4 used in the pickling process,

[0068] After the preform 4 is pickled, it is transported from the pickling machine to the storage point:

[0069] Step S1: The pick-up device is moved above the preform 4, and the nozzle 2 is opened to purge the residual acid on the surface of the preform 4;

[0070] Step S2: the nozzle 2 is closed, the pick-up device is lowered to the position of the preform 4, the suction cup 3 is opened, and the preform 4 is sucked tightly;

[0071] Step S3: The pick-up device lifts the preform 4 and transports it to ...

Abstract

The invention discloses an optical fiber preform rod pickup device for a pickling procedure and a pickup method, and belongs to the field of optical fiber production and manufacturing. The pickup device comprises suction disks, nozzles and a bearing frame, wherein the pickup surface of the bearing frame is a semicylindrical arc-shaped surface; the suction disks and the nozzles are uniformly distributed on the axial direction of the semicylindrical arc-shaped surface; multiple groups of suction disks are in fan-shaped arrangement in the radial direction of the semicylindrical arc-shaped surface. The optical fiber preform rod pickup device for the pickling procedure can be applied to carrying of optical fiber preform rods of different specifications in the pickling procedure.

Description

technical field [0001] The invention belongs to the field of optical fiber production and manufacturing, and relates to an optical fiber preform pick-up device and a pick-up method used in a pickling process. Background technique [0002] The optical fiber preform needs to be put into the pickling machine before drawing, and the surface oil and defects are removed by corrosion. At present, the preform is manually transported to the pickling machine for pickling and corrosion. From the perspective of protecting the handling personnel and reducing the labor load, the use of automated handling in the pickling process is a future trend. However, in order to realize the automation of preform handling in the pickling process, the design of the end fixture is a difficult point, and there are the following difficulties: [0003] 1) There are various specifications of preforms, and the outer diameters vary greatly, so the fixture needs to be able to pick up preforms of different sp...
