Description

Technical Field

[0001] The invention belongs to the technical field of photoelectric couplers and relates to a circular partitioned hollow tray for automatic cleaning of ceramic tube shells. Background Art

[0002] Before bonding the chip of the optocoupler, the ceramic shell needs to be soaked and ultrasonically cleaned with three chemical reagents: toluene, acetone, and anhydrous ethanol. The existing process is to use ordinary discs to stack the ceramic shells on top, and put them into the solution for soaking and ultrasonic cleaning. The ultrasonic process can easily cause the ceramic shells to rub against each other and slip, and during the solution replacement process, the solution remains in the ceramic shell cavity and is not easy to flow out.

[0003] Optocouplers have very high requirements on product appearance. The pins and metal surfaces cannot have obvious damage. The stacking friction of the ceramic shell during cleaning will cause certain scratches on the product pins and metal surfaces; the cleaning solution will remain in the shell, causing contamination to the shell, seriously affecting the appearance quality of the optocoupler product.

[0004] The trays used in the automatic cleaning process must meet the following requirements: the ceramic shells cannot be stacked, the solution can easily penetrate and flow out, the hands cannot touch the solution when the tray is placed or taken out, and the number of cleaning shells on each tray must not be less than 50. There are several difficulties in the tray design:

[0005] 1. The ultrasonic tank of the automatic cleaning machine is 400mm*400mm, so the tray cannot be designed too large;

[0006] 2. Ceramic tube shells cannot be stacked or slide, so the tray must be set up so that each cleaning device is placed separately without touching each other and there is a certain height partition to prevent the device from sliding;

[0007] 3. In order to allow the chemical solution to effectively penetrate and flow out during the cleaning process, there should be gaps in the partition where each tube shell is placed and round holes on the bottom of the tray;

[0008] 4. In order to withstand immersion in chemical solutions and high-temperature baking, all pallet materials must be corrosion-resistant and high-temperature resistant. Summary of the invention

[0009] In view of this, the purpose of the present invention is to solve the cleaning problem of ceramic tube shells and provide a circular partitioned hollow tray for automatic cleaning of ceramic tube shells.

[0010] In order to achieve the above object, the present invention provides the following technical solutions:

[0011] A circular partitioned hollow tray for automatic cleaning of ceramic tube shells, comprising a connecting rod and a tray body, one end of the connecting rod is connected to a fixing plate by a thread, the tray body is sleeved on the connecting rod, and the axial position is limited by the fixing plate;

[0012] The tray body is circular, and is provided with a plurality of coaxially distributed circular partitions and a plurality of circumferentially distributed linear partitions perpendicular to the circular partitions; the circular partitions divide the tray body from the inside to the outside into a plurality of circular areas, and each circular area is further divided into a plurality of circumferentially evenly distributed compartments by linear partitions, and the ceramic tube shell is placed in the compartment;

[0013] The bottom of each compartment is provided with a plurality of evenly distributed leakage holes penetrating the tray body, and the linear partitions and circular partitions constituting each compartment are both provided with side seams, and two adjacent compartments are connected through the side seams.

[0014] Furthermore, there are four circular partitions, which divide the tray body into three circular areas. From the inside to the outside, the number of compartments in the three circular areas is 7, 14, and 21 respectively.

[0015] Furthermore, within the angle area corresponding to each compartment in the innermost circular area of ​​the tray body, the middle circular area corresponds to 2 compartments, and the outermost circular area corresponds to 3 compartments.

[0016] Furthermore, the leakage holes at the bottom of the compartment are circular holes, and 9 of them are distributed in a 3×3 array along the circumference and radial direction in each compartment.

[0017] Furthermore, the connecting rod passes through the center of the tray body, and the fixing plate is located at the bottom of the tray body.

[0018] Furthermore, since the products need to be baked after cleaning, the tray body is made of Peek material.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention designs multiple circular partitions and linear partitions to divide the tray body into multiple independent compartments, each compartment only contains one ceramic tube shell. This structural design ensures that the ceramic tube shells will not contact and stack with each other during the cleaning process, avoiding the problem of damage to the pins and metal surfaces caused by the friction between the ceramic tube shells in the traditional method, effectively ensuring the appearance quality of the product and reducing the probability of damage.

[0021] 2. The present invention designs multiple leakage holes at the bottom of each compartment and opens side seams at the partition. These designs allow the cleaning solution to quickly penetrate into all parts of the ceramic shell, ensuring thorough cleaning. At the same time, the solution can be quickly discharged when the solution is replaced, reducing the situation where the solution remains in the ceramic shell cavity, avoiding secondary pollution caused by residual solution, and significantly improving the cleaning effect.

[0022] 3. The present invention divides the tray into multiple compartments through a partition structure. Each tray can accommodate 63 ceramic tube shells, and stacking and friction are avoided during cleaning, and the cleaning efficiency is significantly improved. It has been verified by actual use that the cleaning efficiency of the present invention is about 50% higher than that of the traditional cleaning method, which greatly reduces the process time and improves production efficiency.

[0023] 3. The present invention reduces the friction damage between the ceramic tube shells through the independent compartment design, and the solution can effectively immerse and flow out, avoiding the problems of incomplete cleaning and residual pollution. According to actual application statistics, after using the tray of the present invention, the appearance qualification rate of the ceramic tube shell is increased by about 60%, which significantly reduces the product scrap rate caused by poor cleaning and improves the overall quality of the optocoupler.

[0024] 4. The tray material used in the present invention is Peek (polyetheretherketone), which has excellent corrosion resistance and high temperature resistance. It can withstand the corrosion of chemical reagents such as toluene, acetone, and anhydrous ethanol during the cleaning process, and can also withstand high-temperature baking processes after cleaning. This feature ensures a long service life of the tray and reduces the cost of replacement and maintenance.

[0025] 5. The tray designed by the present invention is universal and suitable for cleaning ceramic tube shells of various models and sizes. By reasonably designing the size and number of compartments, the tray can meet the automatic cleaning requirements of photoelectric coupler tube shells of different sizes, and has high flexibility and adaptability.

[0026] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] A tray is required for cleaning the ceramic tube shell of the photocoupler. The ceramic tube shells to be cleaned are stacked and placed on the tray, and then the tray is placed in a cleaning solution for immersion and ultrasonic treatment. During this process, the ceramic tube shells are stacked and ultrasonically treated, and friction and solution residues are generated during the ultrasonic treatment, resulting in product failure. For this purpose, the present invention provides a circular partition 13-type hollow tray for automatic cleaning of ceramic tube shells.

[0037] See also Figures 1 to 4, is a circular partitioned hollow tray for automatic cleaning of ceramic tube shells, comprising a connecting rod 2 and a tray body 1, one end of the connecting rod 2 is connected to a fixing disk by a thread, the tray body 1 is sleeved on the connecting rod 2, and the axial position is limited by the fixing disk; the tray body 1 is circular, and a plurality of coaxially distributed circular partitions 13 and a plurality of circumferentially distributed linear partitions 14 perpendicular to the circular partitions 13 are arranged on the tray body 1; the circular partitions 13 divide the tray body 1 from the inside to the outside into a plurality of circular areas, each of which is divided into a plurality of circumferentially evenly distributed compartments by the linear partitions 14, and the ceramic tube shells are placed in the compartments;

[0038] The bottom of each compartment is provided with a plurality of evenly distributed leakage holes 16 penetrating the tray body 1, so that liquid can effectively penetrate and flow out from the bottom surface. The linear partitions 14 and circular partitions 13 constituting each compartment are provided with side seams 15, and two adjacent compartments are connected through the side seams 15.

[0039] There are four circular partitions 13, each 20 mm high, dividing the tray body 1 into three circular areas. From the inside to the outside, the number of compartments in the three circular areas is 7, 14, and 21. In the angle area corresponding to each compartment in the innermost circular area of ​​the tray body 1, the middle circular area corresponds to 2 compartments, and the outermost circular area corresponds to 3 compartments.

[0040] The leakage holes 16 at the bottom of the compartment are circular holes, and 9 holes are distributed in a 3×3 array along the circumference and radial direction in each compartment.

The top of the connecting rod 2 is left as a flat square with a length of 8mm and a cross-sectional size of 8mm×8mm, which is reserved for connecting other tools. The fixing plate 3 is a hexagonal nut with a width of 40mm and a height of 6mm. The center of the tray body 1 is opened, and the connecting rod 2 passes through the center of the tray body 1. The fixing plate is located at the bottom of the tray body 1.

[0042] Since the products need to be baked after cleaning, the tray body 1 is made of Peek material, which is resistant to high temperature and corrosion.

[0043] During specific use, the product of model GH1150J was placed independently and vertically in each compartment, and the entire tray was placed in the washing tank of the automatic cleaning machine. After soaking in toluene, acetone, and anhydrous ethanol and ultrasonication, the tray was taken out and baked at 150°C. After baking, the product was inspected under a microscope at 20 times. There was no damage to the product pins and metal surface, and there was no residual chemical solution contamination inside and outside the product. During the cleaning process, the product did not slip off the tray or rub against each other, proving that the tray can be effectively used as a carrier for the product in the automatic cleaning process.
