Description

Technical Field

[0001] This utility model relates to the field of oxygen sensor technology, and in particular to a zirconium sheet protective layer dip-coating and drying machine. Background Technology

[0002] As a critical automotive component, the oxygen sensor operates in extremely harsh environments, constantly exposed to high temperatures, corrosion, poisoning, moisture, and vibration. This not only severely shortens the sensor's lifespan but also significantly impacts the user experience. To address these issues, a special protective layer is typically added to the oxygen sensor chip to provide stress shock protection and poisoning protection, thereby extending its lifespan.

[0003] Currently, oxygen sensors commonly use zirconium foil protective layers, coated via dip coating, requiring a certain thickness and height. However, existing integrated coating-pull-drying machines have some shortcomings in practical applications. For example, the integrated coating-pull-drying machine disclosed in Chinese Patent Publication No. CN 216459735 U, while meeting the coating requirements of oxygen sensor chips to some extent, has low working efficiency. This device requires drying the zirconium foil protective layer after dip coating, and the drying time is relatively long, typically around half an hour. This means that the next batch of products cannot be dip-coated or pulled until drying is complete, significantly limiting production efficiency.

[0004] Furthermore, the existing mixing device is bolted to the linear guide assembly at the four corners. This fixing method is not only inconvenient to assemble and disassemble, requiring 10 minutes each time, but also reduces work efficiency. In actual operation, frequent disassembly and assembly are not only time-consuming and labor-intensive, but may also lead to equipment damage or loosening of connections, further affecting production efficiency and equipment stability. Summary of the Invention

[0005] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, a zirconium sheet protective layer dip coating and pulling dryer with improved working efficiency is provided.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a zirconium sheet protective layer dip-coating and pulling dryer, including a workbench, on which a dip-coating and pulling device and a drying device are installed, with the drying device located on one side of the dip-coating and pulling device.

[0007] The dip coating lifting device includes a main unit, on which a slurry container mounting base is installed. A slurry container is installed on the slurry container mounting base, and slurry is placed in the slurry container. A column is installed on one side of the slurry container mounting base, and a first linear motor drive module is installed on the column. An installation fixture is installed on the first linear motor drive module via a support arm. A product tray is placed on the installation fixture, and the product tray is located above the slurry container.

[0008] Furthermore, a second linear motor drive module is also installed on the main unit between the first linear motor drive module and the slurry container mounting base. The second linear motor drive module is equipped with a stirring component for stirring the slurry in the slurry container. The second linear motor drive module is also equipped with a guide seat, which is locked to the stirring mounting plate in the stirring component by a locking device.

[0009] Furthermore, guide mounting holes are provided on the plate surface of the guide seat, and guide pins are installed on the four corners of the guide seat; a sensing plate is installed on one side of the guide seat, and a sensor that cooperates with the sensing plate is installed on one side of the second linear motor drive module.

[0010] Furthermore, the mixing assembly includes a mixing motor, a mixing component, and a mixing mounting plate. The mixing motor is mounted on one end of the mixing mounting plate, and the mixing component is mounted on the output end of the mixing motor. The other end of the mixing mounting plate has a locking mounting hole and several limiting holes that cooperate with the guide pins on the guide seat. The center line of the locking mounting hole coincides with the center line of the guide mounting hole in the guide seat. The locking device is inserted into the locking mounting hole and the guide mounting hole.

[0011] Furthermore, a mounting plate is installed on one side of the mounting fixture, and a laser rangefinder is installed on the mounting plate to measure the distance between the mounting fixture and the top surface of the slurry in the slurry container, thereby ensuring the height of the product tray descent and the length of the product dip coating.

[0012] Furthermore, the installation fixture includes a horizontal plate, with opposing vertical plates installed at both ends of the horizontal plate. The suspended ends of the vertical plates are provided with inwardly extending plates, and an installation area for placing the product tray is formed between the two vertical plates. The product tray is placed in this installation area.

[0013] Furthermore, an adjustment elongated hole is provided on the surface of the vertical plate along its length, and the laser rangefinder sensor is installed on the adjustment elongated hole.

[0014] Furthermore, the product tray includes a mounting base, on which several mounting blocks are mounted. Each mounting block has a mounting hole, into which the product is inserted. The mounting hole is an adjustment hole, suitable for products of various specifications.

[0015] Furthermore, the mounting block is made of a soft material to prevent damage to the product.

[0016] Furthermore, the main unit is equipped with control components that control the operation of the dip coating lifting device.

[0017] The beneficial effects of this utility model are as follows: By optimizing the drying device, the drying time is shortened from 30 minutes to 10 minutes, thereby improving production efficiency and enabling faster completion of coating drying and processing of the next batch of products, thus improving overall production efficiency.

[0018] Meanwhile, the locking device makes the disassembly and assembly of the mixing device more convenient, reduces maintenance time and workload, lowers maintenance costs, improves equipment stability, and has a wide range of applications.

[0019] By using a laser rangefinder sensor, the coating thickness of the zirconium sheet protective layer can be more precise, and the coating height can be controlled within ±0.1 mm. This improves the consistency of the zirconium sheet protective layer, enhances the coating accuracy of the equipment, and can be adapted to oxygen sensor zirconium sheets with a length x width of (3 mm to 8 mm) * (1 mm to 3 mm), making the product more competitive in the market.

When one drying device 30 is full, it starts drying, and the other starts packing. They are used alternately to further improve work efficiency, shortening the drying time of the existing invention to 1 / 3 of the original time and increasing production efficiency by 40%. In addition, the main unit 2 is equipped with a control component 32 to control the operation of the dip-coating pull-out device.

[0031] The dip coating lifting device includes a main unit 2, on which a slurry container mounting base 3 is installed, and a slurry container 4 is installed on the slurry container mounting base 3. Slurry is placed in the slurry container 4. A column 5 is installed on one side of the slurry container mounting base 3. A first linear motor drive module 6 is installed on the column 5. An installation fixture 8 is installed on the first linear motor drive module 6 through a support arm 7. A product tray 9 is placed on the installation fixture 8. The product tray 9 is located above the slurry container 4.

[0032] like Figures 3-4As shown, a second linear motor drive module 10 is also installed on the main unit 2 between the first linear motor drive module 6 and the slurry container mounting base 3. The second linear motor drive module 10 is equipped with a stirring assembly 12 for stirring the slurry in the slurry container 4, thereby improving the uniformity of the slurry and preventing slurry sedimentation that could affect the coating effect. A guide seat 11 is installed on the second linear motor drive module 10, and the guide seat 11 is locked to the stirring mounting plate 23 in the stirring assembly 12 by a locking device 15 (commercially available).

[0035] The locking body 34 includes a lock body, in which a mounting hole is provided. A shaft 36 is installed in the mounting hole. A spring is sleeved on the upper end of the shaft 36 and locked by a knob 40. A pin 37 is installed on the lower end of the shaft 36. The shaft 36 and the pin 37 are arranged perpendicularly.

[0036] The cam sleeve 34 includes a sleeve body, on which an elongated hole 38 is provided, and a cam surface 39 is provided at the middle position of the length direction on both sides of the elongated hole 38.

[0037] When the knob 40 is in the OFF position, the built-in spring automatically returns to the released state, and the shaft 36 retracts into the locking body 34. Then the guide seat 11 and the stirring mounting plate 23 are in the open state. At this time, there will be no interference during assembly and disassembly.

The mounting blocks 19 are made of a flexible material, such as silicone or polyurethane, compatible with various zirconium sheet mounting and providing support and protection against damage. They also guide vibration.

[0043] Work process:

[0044] Step 1: Place the product tray 9 containing several products on the installation fixture 8, place the finished slurry in the slurry container 4, place the slurry container 4 on the slurry container mounting base 3, and then pre-set the product dipping height, lifting speed, stirring speed and stirring frequency through the control component 32.

[0045] Step 2: The first linear motor drive module 6 drives the mounting fixture 8 to move down and dip the product on the product tray 9 into the slurry. At the same time, the laser range sensor 17 measures the distance between the mounting fixture 8 and the slurry surface to ensure the dipping data. After completion, the first linear motor drive module 6 drives the mounting fixture 8 to move up and reset.

[0046] Step 3: The operator manually removes the product tray 9 and sends it to the drying device 30 on one side for drying until the product is dried. Then, the product is removed and sent to the next process. At the same time, the two drying devices 30 are used alternately to avoid production interruption.

[0047] Step 4: After a period of time, the second linear motor drive module 10 drives the stirring assembly 12 to stir the slurry in the slurry container 4. After the stirring is completed, it is reset.
