Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a drying device for processing automotive oxygen sensors. Background Technology

[0002] In the automotive manufacturing and repair field, oxygen sensors are key components in the emission control system of automotive engines. Their performance plays a crucial role in the normal operation of the engine and the compliance of exhaust emissions. During the manufacturing process of oxygen sensors, multiple processes are required, among which the cleaning process is essential. After cleaning, a large amount of moisture remains on the surface of the oxygen sensor. If this moisture is not removed in a timely and effective manner, it may corrode the oxygen sensor during subsequent storage, transportation, and assembly, affecting its electrical performance and measurement accuracy, thereby shortening the service life of the oxygen sensor.

[0003] In the manufacturing process of automotive oxygen sensors, the drying process is a crucial step in ensuring product quality. Currently, the drying of automotive oxygen sensors mainly relies on traditional drying equipment and technologies, which have many shortcomings. Traditional drying methods mostly employ static drying, with the oxygen sensor fixed in place, resulting in slow moisture evaporation and a long overall drying time, reducing production efficiency and increasing production costs. On the other hand, the drying uniformity is poor due to the lack of an effective dynamic processing mechanism. During the drying process, the oxygen sensor is subjected to uneven heating and airflow, with some areas retaining more moisture while others may be damaged due to overheating, seriously affecting the performance and service life of the oxygen sensor. Therefore, those skilled in the art provide a drying device for processing automotive oxygen sensors to solve the problems mentioned in the background art. Utility Model Content

The rotating assembly includes a fixed bracket fixedly connected to the top end of the top plate. A first motor is fixedly connected inside the fixed bracket.

[0009] Preferably, the extrusion mechanism includes an electric push rod fixedly connected inside the first gear. The electric push rod is disposed through the protective cover. Several triangular frames are fixedly sleeved on the outer wall of the telescopic rod of the electric push rod. A first block is fixedly connected to each of the three ends of the triangular frames. Three arc-shaped plates are placed in a circular array on the outer wall of the electric push rod. Six guide brackets are fixedly connected in a circular array on the outer wall of the electric push rod, and every two guide brackets form a group.

[0010] Preferably, the end of the arc-shaped plate away from the electric push rod is fixedly connected to six positioning rods that are inserted into positioning holes. Each arc-shaped plate is fixedly connected to three second blocks on the side near the electric push rod. Each second block abuts against the first block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a compression mechanism to limit the storage mechanism. Then, a drive assembly rotates both the compression mechanism and the storage mechanism. Since an oxygen sensor is placed inside the permeable frame, the rotation of the storage mechanism causes the oxygen sensor to rotate rapidly, thereby splashing liquid off its surface and reducing its moisture content. Then, a hydraulic push rod lifts the top plate, and with the help of the rotating assembly, the compression mechanism and the drying mechanism can be interchanged. After the drying mechanism enters the drying chamber, hot air is continuously supplied into the drying chamber through a drying air pipe, causing the temperature inside the drying chamber to rise continuously. The oxygen sensor is further dried by the hot air blowing. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Please see Figures 1-6 As shown, this utility model provides a technical solution: a drying device for processing automotive oxygen sensors, including two hydraulic push rods 1 placed opposite each other and a drying box 3. The telescopic ends of the two hydraulic push rods 1 are fixedly connected to a top plate 2. The drying box 3 is placed below the top plate 2. The interior of the drying box 3 is provided with a storage mechanism 8 for placing oxygen sensors. A squeezing mechanism 7 is provided at the center of the interior of the drying box 3 to limit the storage mechanism 8. A drive assembly 6 is provided at the bottom of the top plate 2 to drive the squeezing mechanism 7 to rotate. A drying mechanism 5 for drying oxygen sensors is provided on one side of the bottom of the top plate 2 located in the drying box 3.

[0024] It should be noted that by setting two hydraulic push rods 1 placed opposite each other, whose telescopic ends are connected to the top plate 2, the height of the top plate 2 can be flexibly adjusted to adapt to different drying needs, making operation convenient. The drying chamber 3 is placed below the top plate 2, and the internal storage mechanism 8 can orderly place the oxygen sensors, keeping them stable during the drying process and preventing them from colliding and being damaged. The extrusion mechanism 7 is located in the center of the drying chamber 3, which limits the storage mechanism 8 and further ensures that the oxygen sensors are fixed in position during drying, improving the drying effect. The drive component 6 at the bottom of the top plate 2 can drive the extrusion mechanism 7 to rotate, making the oxygen sensors in the storage mechanism 8 more evenly heated and avoiding local over- or under-drying. The drying mechanism 5 is located on one side of the drying chamber 3 at the bottom of the top plate 2, which can accurately dry the oxygen sensors, effectively remove moisture, and improve the quality of the oxygen sensors.

[0025] As one implementation method in this embodiment, please refer to Figure 1 and Figure 2As shown, a rotating assembly 4 is provided at the top end of the top plate 2 to drive the drying mechanism 5 and the drive assembly 6 to rotate. The rotating assembly 4 includes a fixed bracket 41 fixedly connected to the top end of the top plate 2. A first motor 42 is fixedly connected inside the fixed bracket 41. A first drive rod 43 is fixedly connected to the output end of the first motor 42. A fixed plate 44 is fixedly connected to the end of the first drive rod 43 away from the first motor 42. The fixed plate 44 is located below the top plate 2. The first drive rod 43 extends to the bottom of the top plate 2 and is rotatably sleeved with the contact surface of the top plate 2 through a bearing. A connecting shaft 45 is fixedly connected to the bottom end of the fixed plate 44 on one side of the drive assembly 6.

[0026] It should be noted that the first motor 42 drives the fixed plate 44 to rotate through the first drive rod 43. The first drive rod 43 and the top plate 2 are rotated and sleeved through the bearing, which makes the rotation process smooth and reduces friction, thereby reducing energy consumption and wear. During the rotation, the drive assembly 6 can cause the squeezing mechanism 7 to apply force to the storage mechanism 8 from different directions, thereby driving the storage mechanism 8 to rotate and accelerate drainage through the drive assembly 6.

[0027] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, the storage mechanism 8 includes three permeable frames 81 arranged in an upper and lower structure. Each permeable frame 81 has several connecting rods 83 fixedly connected to one side of its opposite side in a circular array. The connecting rods 83 are used to connect the permeable frames 81 to each other. Each permeable frame 81 has several rubber placement racks 82 fixedly connected to its inner circular array for placing oxygen sensors. Each permeable frame 81 has positioning holes 84 on its inner sidewall.

[0028] It should be noted that the three permeable frames 81 arranged in an upper and lower structure provide layered placement space for oxygen sensors, allowing for the drying of multiple oxygen sensors at once, effectively improving drying efficiency. The permeable frames 81 are interconnected by several connecting rods 83, ensuring a stable structure and preventing the oxygen sensors from being damaged by shaking during the drying process. Several rubber placement racks 82 are fixedly connected in a ring array inside each permeable frame 81. The rubber material is elastic and can well conform to the shape of the oxygen sensor, effectively fixing it and preventing the oxygen sensor from moving during drying. It also plays a buffering role, preventing scratches on the surface of the oxygen sensor. Moreover, the ring array distribution of the rubber placement racks 82 makes the oxygen sensors placed in an orderly manner, facilitating retrieval and management. In addition, the positioning holes 84 opened on the inner side wall of each permeable frame 81 can cooperate with the extrusion mechanism 7 to achieve precise positioning.

[0029] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3As shown, the drive assembly 6 includes a second motor 61 fixedly connected to the top of the fixed plate 44. The output end of the second motor 61 is fixedly connected to a second drive shaft 611. A protective cover 63 is fixedly connected to the bottom end of the fixed plate 44. A first gear 62 and a second gear 64 are rotatably sleeved inside the protective cover 63. The first gear 62 and the second gear 64 mesh and drive each other. The end of the second drive shaft 611 extends into the interior of the protective cover 63, and the end of the second drive shaft 611 away from the second motor 61 is fixedly connected to the top of the second gear 64. The contact surface between the second drive shaft 611 and the fixed plate 44 is rotatably sleeved through a bearing.

[0030] It should be noted that the second motor 61 is fixed to the top of the fixed plate 44, providing power for the entire driving process. The second drive shaft 611 connected to its output end is rotatably sleeved with the fixed plate 44 through bearings, ensuring smooth rotation and reducing energy loss and mechanical wear. The protective cover 63 at the bottom of the fixed plate 44 protects the first gear 62 and the second gear 64 inside, preventing dust, debris and other objects from entering and affecting gear transmission, thus extending the service life of the gears.

[0031] As one implementation method in this embodiment, please refer to Figure 3 and Figure 4 As shown, the extrusion mechanism 7 includes an electric push rod 71 fixedly connected inside the first gear 62. The electric push rod 71 is through the protective cover 63. Several triangular frames 73 are fixedly sleeved on the outer wall of the telescopic rod of the electric push rod 71. The three ends of each triangular frame 73 are fixedly connected to a first block 74. Three arc-shaped plates 75 are arranged in a circular array on the outer wall of the electric push rod 71. Six guide brackets 72 are fixedly connected in a circular array on the outer wall of the electric push rod 71, with each pair of guide brackets 72 forming a group. The end of the arc-shaped plate 75 away from the electric push rod 71 is fixedly connected to... There are six positioning rods 76 that are inserted into the positioning holes 84. Each arc plate 75 has three second blocks 77 fixedly connected to the side near the electric push rod 71. Each second block 77 abuts against the first block 74. Two guide blocks 78 are symmetrically fixedly connected to the upper and lower ends of each arc plate 75. Each arc plate 75 is slidably sleeved with the guide bracket 72 through the guide blocks 78. A triangular guide frame 79 is provided below the electric push rod 71. The lower top of each arc plate 75 is slidably sleeved inside the triangular guide frame 79 through the guide blocks 78.

[0032] It should be noted that the electric push rod 71 is fixed inside the first gear 62 and can rotate with the first gear 62 to achieve a compound motion of rotation and extension. It can flexibly adjust the extrusion position and force. The triangular frame 73 on the outer wall of the extension rod cooperates with the first block 74 and abuts against the second block 77 to evenly transmit the extension force of the electric push rod 71 to the arc plate 75, so that the arc plate 75 is subjected to balanced force. The three arc plates 75 are slidably connected to the guide bracket 72 through the guide block 78, and the lower end is slidably connected to the triangular guide frame 79 through the guide block 78. This design makes the movement of the arc plate 75 smooth and precise, without deviation, ensuring that the positioning rod 76 can be accurately inserted into the positioning hole 84 of the permeable frame 81 to achieve precise positioning of the storage mechanism 8. The six guide brackets 72 are divided into three groups, which play a good guiding and supporting role for the arc plate 75 and improve the stability of the entire extrusion mechanism 7.

[0033] As one implementation method in this embodiment, please refer to Figure 5 and Figure 6 As shown, the drying mechanism 5 includes a connecting plate 51 fixedly connected to the lower end of the connecting shaft 45. Several drying air pipes 52 are fixedly connected in a ring array at the lower end of the connecting plate 51. Each drying air pipe 52 has an air inlet pipe 53 fixedly connected to its air inlet end, and each air inlet pipe 53 is interconnected. One of the air inlet pipes 53 has an air delivery pipe 54 fixedly connected to its air inlet end. The end of the air delivery pipe 54 is connected to an external hot air blower. A drain pipe 31 is fixedly connected to the drain end of the drying box 3. An electric control valve 32 is installed on the outer wall of the drain pipe 31. A base 33 is fixedly connected to the inner bottom end of the drying box 3. The lower bottom end of the triangular guide frame 79 has a docking hole corresponding to the base 33.

[0034] It should be noted that the several drying air pipes 52 fixedly connected in a ring array at the bottom of the connecting plate 51 increase the hot air coverage area, enabling simultaneous drying of multiple oxygen sensors and improving drying efficiency. Each drying air pipe 52 is fixedly connected to an air inlet pipe 53, and one of the air inlet pipes 53 is connected to a delivery pipe 54, which is connected to an external hot air blower. This design ensures that hot air is evenly and stably delivered to each drying air pipe 52, guaranteeing consistency in drying temperature and air velocity, and providing a good drying environment for the oxygen sensors. During the drying process, the hot air directly acts on the oxygen sensors through the drying air pipes 52. The device can quickly remove moisture, shorten drying time, and improve production efficiency. The drain pipe 31 is fixedly connected to the drain end of the drying box 3, which can promptly discharge the water generated during the drying process, avoiding water accumulation that affects the drying effect and normal operation of the equipment. The electric control valve 32 installed on the outer wall of the drain pipe 31 can accurately control the drainage time and flow rate, realize automated drainage operation, and eliminate the need for frequent manual intervention, thereby improving production efficiency and reducing labor costs. The docking holes at the bottom of the triangular guide frame 79, which correspond to the base 33, make the docking between the triangular guide frame 79 and the base 33 more precise and stable, further enhancing the structural stability of the entire drying device.

[0035] Working principle: First, the oxygen sensor is placed on the rubber placement rack 82 inside the permeable frame 81 of the storage mechanism 8. The permeable frame 81 is connected to each other through the connecting rod 83 to form a layered structure, which facilitates the batch placement of oxygen sensors. Then, the extrusion mechanism 7 starts to work, the electric push rod 71 is activated, and the triangular frame 73 on the outer wall of its telescopic rod drives the first block 74 to move. The first block 74 abuts against the second block 77 on the arc plate 75, pushing the arc plate 75 to slide in the guide bracket 72 and the triangular guide frame 79 through the guide block 78, so that the positioning rod 76 at one end of the arc plate 75 is inserted into the positioning hole 84 on the inner side wall of the permeable frame 81, thereby achieving precise positioning of the storage mechanism 8.

[0036] The second motor 61 of the drive assembly 6 starts, driving the second gear 64 to rotate via the second drive shaft 611. The second gear 64 meshes with the first gear 62, thereby driving the electric push rod 71 fixed inside the first gear 62 to rotate, causing the storage mechanism 8 to rotate rapidly. The liquid on the surface of the oxygen sensor is thrown out under centrifugal force, reducing the water content. After the water is thrown out, the hydraulic push rod 1 starts, driving the top plate 2 to rise. At the same time, the first motor 42 of the rotating assembly 4 starts, driving the fixed plate 44 to rotate via the first drive rod 43, causing the connecting shaft 45 to drive the drying mechanism 5 into the drying chamber. Inside the drying chamber 3, the air supply pipe 54 of the drying mechanism 5 is connected to the external hot air blower. Hot air enters each drying air pipe 52 through the air inlet pipe 53 and is blown out from the drying air pipe 52, causing the internal temperature of the drying chamber 3 to rise continuously. The hot air continuously blows on the oxygen sensor to further dry it. The condensate and other water generated during the drying process are discharged through the drain pipe 31 at the drain end of the drying chamber 3. The electric control valve 32 on the outer wall of the drain pipe 31 can accurately control the drainage. The base 33 at the bottom of the drying chamber 3 corresponds to the docking hole at the bottom of the triangular guide frame 79, providing stable support for the entire device and ensuring the smooth progress of the drying process.

[0037] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
