Description

Technical Field

[0001] The invention belongs to the technical field of optical fiber ring pretreatment, and relates to an optical fiber ring adhesive ring shell pretreatment, automatic glue brushing device and method. Background Art

[0002] As the core component of the fiber optic gyroscope, the fiber optic ring directly determines the performance of the fiber optic gyroscope. At present, most of the glue brushing on the ring shell is done by hand or by screw valve glue brushing equipment. Manual glue brushing generally adopts the method of "more back and less supplement", which cannot ensure the uniformity of glue brushing. The glue brushed by the screw valve equipment is in the form of lines after glue is applied. The glue needs to be leveled before the ring body can be bonded. However, the diffusion range of the glue is not controllable, so the uniformity of glue brushing cannot be controlled. In order to improve the reliability and product performance of the fiber optic ring, the fiber optic ring is bonded and fixed to the metal shell base with structural adhesive. The weight accuracy and uniformity of the shell glue brushing directly affect the consistency and reliability of the product performance after the ring is bonded, thereby affecting the product quality.

DETAILED DESCRIPTION

[0025] like Figure 1~Figure 5In the invention, a fiber ring adhesive ring shell pretreatment and automatic glue brushing device is provided. The clamping weighing mechanism, touch screen 71 and connecting mechanism are fixed on the upper end surface of the box body 1. The laser rangefinder 3 and plasma surface treatment machine and plasma surface treatment machine 56 are connected to one side of the upper end of the connecting mechanism, and the distance position with the clamping weighing mechanism is adjusted by telescopic movement. The high-precision tool setting sensor 8 is fixed on the side where the connecting mechanism is connected to the box body 1. The height with the shell is automatically determined by the equipment, and the device moves to the top of the shell for processing, which reduces the possibility of operational errors.

[0026] Furthermore, the clamping weighing structure includes a clamping mechanism 21, a pressure sensor 22, an origin sensor 23, a synchronous pulley 24, a conductive slip ring 25, a rotating shaft 26, and a rotating table 27; the upper end of the rotating shaft 26 is connected to the rotating table 27, the clamping mechanism 21 is installed on the upper end surface of the rotating table 27, the pressure sensor 22 is located inside the rotating table 27, the origin sensor 23 is installed on the outer side of the lower end surface of the rotating table 27, and the synchronous pulley 24 and the conductive slip ring 25 are connected to the rotating shaft 26. The weight of the pre-processed shell is determined by the pressure sensor 22 to ensure the subsequent glue brushing weight control.

[0027] Furthermore, the rotating platform 27 is cylindrical, and the clamping mechanism 21 clamps the pre-processing shell in a centered manner. The clamping mechanism 21 fixes the pre-processing shell to prevent shaking.

[0028] Furthermore, the rotating shaft 26 is connected to the box 1, the synchronous pulley 24 is located at the interval between the rotating table 27 and the box 1, and the conductive slip ring 25 is located inside the box 1 and connected to the rotating shaft 26. Data connection with the device is realized.

[0029] Furthermore, the connection mechanism includes a first slide rail 41, a second slide rail 42, and a fixed plate 43; the first slide rail 41 is installed on the upper end surface of the box body 1, the second slide rail 42 is connected and slidably matched with the fixed plate 43, and the fixed plate 43 is connected to the second slide rail 42 perpendicular to the upper end surface of the box body 1. The connection structure is moved to the top of the rotating table 27 for processing.

[0030] Furthermore, the fixed plate 43 includes a first slide groove 431 and a second slide groove 432; the first slide groove 431 and one side of the second slide groove 432 are longitudinally fixed to the fixed plate 43 in parallel, one side of the plasma surface treatment machine is slidably matched with the first slide groove 431, and the plasma surface treatment machine 56 is slidably matched with the second slide groove 432. The plasma surface treatment machine 56 and the plasma surface treatment machine can more conveniently perform glue brushing and surface treatment.

[0031] Furthermore, the data input device includes a touch screen 71 and a support structure 72; the support structure 72 is vertically mounted on the upper end surface of the box 1, and one side of the touch screen 71 is fixedly connected to one side of the upper part of the support structure 72, making manual operation and data input more convenient.

[0032] Furthermore, the plasma surface treatment machine and the plasma surface treatment machine 56 are fixed to the fixed plate 43 and are installed above the rotating table 27 for telescopic movement, thereby improving the stability of the plasma surface treatment machine and the plasma surface treatment machine 56 and avoiding shaking that affects product quality.

[0033] Example Two groups of comparative experiments were conducted, with three samples in each group. The first group did not pre-treat the shell and directly applied glue to the ring. The second group applied plasma surface treatment to the shell and completed the ring in the same way. After the same curing, aging and aging conditions, the preparations before the tensile strength performance test were completed. The tensile strength test experimental tooling was designed, such as Figure 5 shown.

[0034] The two sets of test data are shown in the following table:

[0035] The data was analyzed and it was found that the tensile strength of the samples with surface pretreatment (plasma surface treatment) of the adhesive ring shell was increased by 9.4% on average compared with the samples without surface treatment. This verifies that plasma surface treatment has a significant improvement on the mechanical properties of the adhesive ring product.

[0036] Furthermore, the above-mentioned pretreatment of the optical fiber ring adhesive ring housing, the housing pretreatment of the automatic glue brushing device and the automatic glue brushing method include the following steps: S1, loading, loading the plasma surface treatment machine 56, installing the hose and needle; S2, input data, input parameters such as shell outer diameter, ring inner diameter and glue weight on the touch screen 71; S3, clamping and weighing, placing the shell to be glued on the rotating table 27, the clamping mechanism clamps the shell in a centered manner, and the pressure sensor 22 weighs and automatically records the weight of the shell; S4, measuring and adjusting the distance, the connecting mechanism makes the plasma surface treatment machine and the plasma surface treatment machine 56 run above the tool setting sensor, and the laser rangefinder 3 runs above the shell. The equipment automatically determines the height that the plasma surface treatment machine needs to reach, and at the same time determines whether the shell is clamped in place; S5, pretreatment, the plasma surface treatment machine runs to the position specified after the equipment calculation, and performs plasma surface treatment on the pretreatment shell; S6, glue brushing treatment, the plasma surface treatment machine 56 runs to the specified problem to automatically brush glue, and the shell after brushing glue is weighed through the pressure sensor 22. The equipment calculates whether the operation is qualified and outputs relevant information.

[0037] Furthermore, the optical fiber ring bonding ring shell pretreatment, the shell pretreatment of the automatic glue brushing device and the automatic glue brushing method as described above, when the shell has completed the pretreatment and glue brushing treatment through the plasma surface treatment machine and the plasma surface treatment machine 56, it is automatically reset through the connecting mechanism for continuous operation processing.

[0038] In the above method, during the pretreatment of the optical fiber adhesive ring shell and the automatic glue brushing process, the operation is safe and reliable. Even if there are differences in the shell size, the surface will be plasma treated by the clamping weighing mechanism and the plasma surface treatment machine 56 and the plasma surface treatment machine so that the plasma surface treatment machine 56 can evenly treat the glue brushing, and the clamping weighing mechanism ensures the weight of the glue brushing.
