Description

Technical Field

[0001] This utility model belongs to the field of optical fiber processing equipment, and specifically relates to an ultrasonic cleaning tank for an optical fiber connector polishing machine. Background Technology

[0002] During the production process, fiber optic connectors require multiple grinding processes, and each grinding process necessitates a cleaning. Ultrasonic cleaning is typically used for this purpose. Existing ultrasonic cleaning equipment includes a cleaning tank, an ultrasonic generator located within the tank, and a support assembly for supporting the grinding disc. However, when the cleaning solution is drained after each cleaning cycle, some of the used cleaning solution remains on the support assembly, affecting the cleanliness of the cleaning solution for subsequent cleaning cycles and thus impacting the cleaning effect. Summary of the Invention

[0003] The purpose of this invention is to provide an ultrasonic cleaning tank for a fiber optic connector polishing machine, which can fully drain the used cleaning fluid, thereby ensuring the cleaning effect during the next cleaning.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an ultrasonic cleaning tank for a fiber optic connector polishing machine, comprising:

[0005] The box-shaped structure is open from top to bottom;

[0006] A base plate is installed inside the box and divides the box into an upper cavity and a lower cavity. The base plate is provided with a water inlet and a water outlet.

[0007] An ultrasonic generator is mounted on the base plate and located within the lower cavity;

[0008] The support assembly includes several support plates located above the base plate and within the upper cavity, and first positioning blocks fixed to each of the support plates. All the first positioning blocks form an installation station. Each support plate has a vertically penetrating first through hole and a first mounting hole. Each first positioning block has a vertically penetrating first adjustment hole. The first positioning blocks are fixedly connected to the support plates via bolt assemblies that pass through both the first mounting hole and the first adjustment hole. During cleaning, the fiber optic connector grinding disc is positioned within the installation station. Cleaning fluid enters the upper cavity through the inlet and remains within the upper cavity. At this time, the outlet is closed, and the ultrasonic generator operates for a set time before pausing. The outlet is then opened to discharge the cleaning fluid. Because the support plates and the first positioning blocks have the first through hole and the first adjustment hole respectively, the cleaning fluid can be smoothly discharged from the upper cavity without remaining in the upper cavity and affecting the next cleaning. The outlet does not extend beyond the upper surface of the base plate.

[0009] In another embodiment, the first positioning block is L-shaped, and all the first positioning blocks are grouped in pairs. Each group of first positioning blocks is arranged opposite to each other. The first positioning blocks in each group are arranged sequentially along the first direction to form an installation position in which movement in the first direction is unrestricted but movement in the second direction is restricted. The first direction and the second direction are perpendicular to each other and parallel to the lower end face of the box. The first positioning block restricts the degree of freedom of movement of the grinding disc in the second direction and precisely defines the position of the grinding disc in the second direction. A water guide groove communicating with the first adjustment hole is provided on the lower end face of the first positioning block.

[0010] In another embodiment, the box is a rectangular box, and the support plate is fixed to the four corners of the inner side of the box; the support plate is fixed to the four corners of the box and is fixedly connected to the two sides adjacent to the box, which not only provides an installation position for the first positioning block but also improves the strength of the box.

[0011] In another embodiment, the support assembly further includes a second positioning block disposed on the support plate and located at both ends of the first positioning block in the first direction. The second positioning block and the first positioning block form an installation station in which movement in both the first and second directions is restricted. The second positioning block restricts the degree of freedom of movement of the grinding disc in the first direction and precisely defines the position of the grinding disc in the first direction. Combined with the first positioning block and the second positioning block, the grinding disc is stably set in the installation station.

[0012] In another embodiment, the first positioning block has a second through hole on its side wall, and the second positioning block has a second adjustment hole on its side wall. The second positioning block is fixedly connected to the first positioning block by a bolt assembly that passes through both the second through hole and the second adjustment hole. The second adjustment hole allows the second positioning block to be adjustablely mounted on the support plate and the first positioning block in a first direction, so that the ultrasonic cleaning tank can be used for grinding discs of different sizes. Both the first adjustment hole and the second adjustment hole are oblong holes.

[0013] In another embodiment, an inlet pipe is provided on the inlet, which is located in the lower cavity and connected to the upper cavity; an outlet pipe is provided on the outlet, which is located in the lower cavity and connected to the upper cavity; the inlet pipe and the outlet pipe are arranged in the vertical direction, and neither is perpendicular to the bottom plate, so they will not interfere with the side wall of the lower cavity of the box, which facilitates their installation.

[0014] In another embodiment, the base plate is inclined to the lower end face of the tank, and the water outlet is located on the lower side of the base plate; when it is necessary to discharge the cleaning fluid, the cleaning fluid can be discharged quickly and completely without any residue.

[0015] In another embodiment, the ultrasonic cleaning tank further includes a baffle plate disposed on the base plate and located above the water inlet; the baffle plate can prevent the cleaning fluid flowing into the upper cavity from flowing too fast and impacting the grinding disc or even overflowing from the top of the upper cavity.

[0016] In another embodiment, the baffle plate includes a transverse portion disposed above the water inlet and a longitudinal portion extending downward along the edge of the transverse portion to the space between the water inlet and the water outlet. The lower end of the longitudinal portion is suspended above the base plate, and a notch is provided on the longitudinal portion that extends in a first direction. The notch allows the cleaning fluid to be evenly distributed into the upper cavity when injected, preventing the cleaning fluid in the upper cavity from flowing in one direction, which is not conducive to cleaning the fiber optic connector on the polishing disc.

[0017] In another embodiment, the ultrasonic generator is evenly distributed on the lower end surface of the base plate, and its effective penetration distance is L, which is 50mm≤L≤150mm, and more preferably 90mm≤L≤100mm. The ultrasonic generator is connected to the base plate by planting bolts and welding, and the planting bolts are fully welded to the base plate. When installing the ultrasonic generator, it is glued with anaerobic adhesive and locked with a torque wrench.

[0018] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: During cleaning, the fiber optic connector grinding disc is placed in the installation station, and the cleaning fluid enters the upper cavity from the inlet and is stored in the upper cavity. At this time, the outlet is closed, the ultrasonic generator stops working after the set time, and the outlet is opened to discharge the cleaning fluid. Since the support plate and the first positioning block are respectively provided with the first through hole and the first adjustment hole, the cleaning fluid can be smoothly discharged from the upper cavity without remaining in the upper cavity and affecting the next cleaning. The outlet does not exceed the upper end face of the bottom plate. Attached Figure Description

[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] See Figure 1 and Figure 2 As shown, the ultrasonic cleaning tank of the fiber optic connector polishing machine includes: a housing 1, a base plate 2, an ultrasonic generator 3, a support assembly 4, and a baffle plate 5. The housing 1 is vertically connected. The base plate 2 is installed inside the housing 1 and divides the housing 1 into an upper cavity 11 and a lower cavity 12. The base plate 2 is provided with a water inlet 21 and a water outlet 22. The ultrasonic generator 3 is installed on the base plate 2 and located inside the lower cavity 12. The baffle plate 5 is located on the base plate 2 and above the water inlet 21.

[0027] Specifically, the support assembly 4 includes several support plates 43 located above the base plate 2 and within the upper cavity 11, first positioning blocks 41 and second positioning blocks 42 fixed to each support plate 43, and an installation station O formed between all the first positioning blocks 41. The support plates 43 are provided with a first through hole 431 and a first mounting hole 432 that pass through vertically. The first through hole 431 is located on the part of the support plate 43 that is not covered by the first positioning blocks 41 and the second positioning blocks 42. The first positioning blocks 41 are provided with a first adjustment hole 411 that passes through vertically. The first positioning blocks 41 are fixed to the support plates 43 by bolt assemblies that pass through both the first mounting hole 432 and the first adjustment hole 411. For fixed connection, a water guide groove 413 communicating with the first adjustment hole 411 is opened on the lower end surface of the first positioning block 41; during cleaning, the fiber optic connector grinding disc is placed in the installation position O, and the cleaning fluid enters the upper cavity 11 from the water inlet 21 and is stored in the upper cavity 11. At this time, the water outlet 22 is closed, the ultrasonic generator 3 stops working after working for a set time, and the water outlet 22 is opened to discharge the cleaning fluid. Since the support plate 43 and the first positioning block 41 are respectively provided with the first through hole 431 and the first adjustment hole 411, the cleaning fluid can be smoothly discharged from the upper cavity 11 without remaining in the upper cavity 11 and affecting the next cleaning. The water outlet 22 does not exceed the upper end surface of the bottom plate 2.

[0028] The housing 1 is a rectangular housing with chamfered edges at the top to prevent scratches. Support plates 43 are fixed to the four corners of the inner side of the housing 1. The support plates 43 are fixed to the four corners of the housing 1 and are also fixedly connected to the two adjacent sides of the housing 1, providing an installation position for the first positioning block 41 and increasing the strength of the housing 1. The first positioning block 41 and the second positioning block 42 are both L-shaped. All first positioning blocks 41 are arranged in pairs, with each pair of first positioning blocks 41 facing each other. Each pair of first positioning blocks 41 is arranged sequentially along the first direction X to form an installation position O that allows unrestricted movement along the first direction X but restricts movement along the second direction Y. The first direction X and the second direction Y are perpendicular and parallel to the lower surface of the housing 1. The first positioning blocks 41 restrict the degree of freedom of movement of the grinding disc in the second direction Y and precisely define the position of the grinding disc in the second direction Y. The second positioning block 42 is disposed on the support plate 43 and located on both ends of the first positioning block 41 in the first direction X. The second positioning block 42 and the first positioning block 41 form an installation position O in which movement in both the first direction X and the second direction Y is restricted. The second positioning block 42 restricts the degree of freedom of movement of the grinding disc in the first direction X and precisely defines the position of the grinding disc in the first direction X. Combined with the first positioning block 41 and the second positioning block 42, the grinding disc is stably set in the installation position O. The side wall of the first positioning block 41 is provided with a second through hole 412, and the side wall of the second positioning block 42 is provided with a second adjustment hole 421. The second positioning block 42 is fixedly connected to the first positioning block 41 by a bolt assembly that passes through the second through hole 412 and the second adjustment hole 421 simultaneously. The second adjustment hole 421 allows the second positioning block 42 to be adjusted and installed on the support plate 43 and the first positioning block 41 in the first direction X, so that the ultrasonic cleaning tank can be used for grinding discs of different sizes. Both the first adjustment hole 411 and the second adjustment hole 421 are oblong holes.

[0029] The inlet 21 is equipped with an inlet pipe 211, which is located inside the lower cavity 12 and connected to the upper cavity 11. The outlet 22 is equipped with an outlet pipe 221, which is located inside the lower cavity 12 and connected to the upper cavity 11. The inlet pipe 211 and the outlet pipe 221 are arranged vertically and are not perpendicular to the bottom plate 2, so they will not interfere with the side wall of the lower cavity of the housing 1, facilitating their installation. The bottom plate 2 is inclined to the lower end face of the housing 1, and the outlet 22 is located on the lower side of the bottom plate 2. This side of the bottom plate 2 is equipped with an inclined guide plate 6 connected between the bottom plate and the side wall of the housing for guiding the cleaning fluid into the outlet 22. When the cleaning fluid needs to be discharged, it can be discharged quickly and completely without any residue.

[0030] The baffle plate 5 includes a transverse portion 51 located above the inlet 21 and a longitudinal portion 52 extending downward from the edge of the transverse portion 51 to the space between the inlet 21 and the outlet 22. The lower end of the longitudinal portion 52 is suspended above the base plate 2 and a notch 53 extending through the longitudinal portion 52 in the first direction X is provided. The baffle plate 5 can prevent the cleaning fluid flowing into the upper cavity 11 from the inlet 21 from flowing too fast and impacting the grinding disc or even overflowing from the top of the upper cavity 11. The notch 53 allows the cleaning fluid to be evenly distributed in the upper cavity 11 when injected, preventing the cleaning fluid in the upper cavity 11 from flowing in one direction, which is not conducive to cleaning the fiber optic connector on the grinding disc. It also prevents the cleaning fluid from directly washing the housing, causing the cleaning fluid to splash out of the housing and making the grinding machine production line panel wet.

[0031] The ultrasonic generators 3 are evenly arranged on the lower end surface of the base plate 2. The number of them can be 1, 2, 3, ..., 8, 9, 10, ... In this embodiment, there are 9 of them, arranged in a 3×3 rectangular array. The effective penetration distance is L, which is 50mm≤L≤150mm, and more preferably 90mm≤L≤100mm. The ultrasonic generators 3 are connected to the base plate 2 by welding with planting bolts 31, and the planting bolts 31 are fully welded to the base plate 2. When installing the ultrasonic generators 3, they are glued with anaerobic adhesive and locked with a torque wrench.
