Description

Technical Field

[0001] This utility model relates to the field of chip testing, and in particular to a chip corrosion resistance testing machine. Background Technology

[0002] Chip corrosion resistance testing is a crucial step in ensuring that chips can work reliably in harsh environments. After chip processing, chips are sampled and tested, one of which involves placing the chips in a salt spray environment to test their corrosion resistance.

[0003] For example, patent document CN221351146U discloses a chip corrosion resistance testing machine. The chip is placed on a perforation tray, and multiple trays are inserted into a mounting cavity. A pump draws salt spray test liquid from the mounting cavity, which is then sprayed into the cavity through nozzles to test the chip's corrosion resistance. After the sprayed salt spray liquid accumulates, it is discharged through an outlet and falls into a storage cavity, achieving the purpose of salt spray liquid recovery. However, because the salt spray is sprayed from top to bottom, the distribution of salt spray in the mounting cavity is not uniform, with a higher salt spray concentration at the top than at the bottom. This uneven contact between the upper and lower chips and the salt spray leads to a higher degree of corrosion on the upper chips than on the lower chips, resulting in inaccurate test results. Utility Model Content

[0004] The purpose of this invention is to provide a chip corrosion resistance testing machine to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A chip corrosion resistance testing machine includes a housing with a door hinged to one end. A spray mechanism is located at the top of the housing, and a waste liquid collection mechanism is located at the bottom. A rotating mechanism is located inside the housing, comprising two supports fixed to the bottom of the housing. A rotating ring is rotatably connected to the top of each support. A guide rail is fixedly connected between the two rotating rings, and a support plate with multiple layers is inserted into the guide rail. A transmission mechanism and a turbulence mechanism are located at the end of the housing furthest from the door. The transmission mechanism drives the rotating rings to rotate, and the turbulence mechanism accelerates airflow and provides power to the transmission mechanism.

[0006] Preferably, the support plate includes a carrying mesh plate, which is inserted into the guide rail. The bottom of the carrying mesh plate is mesh-like, and a mesh cover plate is hinged to the top of the carrying mesh plate. A locking bolt is threaded to one end of the carrying mesh plate.

[0007] Preferably, the transmission mechanism includes a gear ring, which is fixedly connected to a rotating ring at the end away from the box door. The gear ring meshes with a gear, and a rotating shaft is fixedly connected to the gear. One end of the rotating shaft is rotatably connected to the side wall of the box, and a bearing seat is rotatably connected to the rotating shaft. The bearing seat is fixedly connected to the inner bottom wall of the box.

[0008] Preferably, the turbulence mechanism includes a motor, which is fixedly connected to one side of the housing. The output end of the motor extends into the housing and is fixedly connected to a fan blade. A drive pulley is fixedly connected to the output end of the motor, and a driven pulley is connected to the drive pulley via a belt. The driven pulley is fixedly connected to the rotating shaft.

[0009] Preferably, the spraying mechanism includes a liquid storage tank, which is fixedly connected to the top of the tank body. A water pump is fixed inside the liquid storage tank, and the water outlet of the water pump is connected to a delivery pipe. Multiple nozzles are fixed at the bottom of the delivery pipe.

[0010] Preferably, the waste liquid collection mechanism includes a waste liquid tank, which is fixedly connected to the bottom of the tank body. The bottom wall of the tank body has a slot corresponding to the waste liquid tank. A filter screen is inserted into the waste liquid tank, and a drain pipe is fixedly connected to one side of the waste liquid tank.

[0011] The beneficial effects are as follows: the turbulence mechanism drives the rotating ring to rotate through the transmission mechanism, and the rotating ring drives the carrier plate to rotate through the guide rail, thereby causing the chip inside the carrier plate to move within the chamber. At the same time, the turbulence mechanism can promote the airflow within the chamber, making the salt spray more evenly distributed within the chamber, and allowing the chip to have more uniform contact with the salt spray, thus improving the accuracy of detection. The carrier plate includes a carrying mesh plate and a mesh cover plate. The chip is placed inside the carrying mesh plate, and the mesh cover plate can press down on the chip after it is closed, thereby fixing the chip inside the carrying mesh plate and preventing the chip from colliding and rubbing during movement.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] The present invention will be further described below with reference to the accompanying drawings: like Figures 1-8As shown, a chip corrosion resistance testing machine includes a housing 1 with a door hinged to one end. A spraying mechanism 2 is installed at the top of the housing 1, and a waste liquid collection mechanism 3 is installed at the bottom of the housing 1. A rotating mechanism 4 is installed inside the housing 1. The rotating mechanism 4 includes two supports 401, which are fixed to the bottom of the housing 1 by screws. A rotating ring 402 is rotatably connected to the top of the supports 401. A guide rail 403 is fixedly connected between the two rotating rings 402. A support plate 5 is inserted into the guide rail 403. The support plate 5 has two layers and is used to place the chip. When the rotating ring 402 rotates, it drives the support plate 5 to rotate, so that the chip moves in a circular motion inside the housing 1, allowing the chip to come into uniform contact with the salt spray. A transmission mechanism 6 and a turbulence mechanism 7 are installed at the end of the housing 1 away from the door. The transmission mechanism 6 is used to drive the rotating ring 402 to rotate, and the turbulence mechanism 7 is used to accelerate the airflow and provide power to the transmission mechanism 6.

[0018] The carrier plate 5 includes a carrying mesh plate 501, which is inserted into the guide rail 403. The carrying mesh plate 501 is kept relatively stationary with the guide rail 403 by friction, preventing the carrying mesh plate 501 from coming out of the guide rail 403 when the rotating ring 402 rotates. The bottom of the carrying mesh plate 501 is mesh-like, and a mesh cover plate 502 is hinged to the top of the carrying mesh plate 501. A locking bolt 503 is threaded to one end of the carrying mesh plate 501. The chip is placed inside the carrying mesh plate 501, and the mesh cover plate 502 is covered. Then, the locking bolt 503 is rotated, and the locking bolt 503 abuts against the mesh cover plate 502, thereby locking the mesh cover plate 502. The mesh cover plate 502 will press the chip, thereby fixing the chip between the carrying mesh plate 501 and the mesh cover plate 502, preventing the chip from colliding and rubbing when the rotating ring 402 rotates.

[0019] The transmission mechanism 6 includes a gear ring 601, which is fixedly connected to a rotating ring 402 at the end away from the door. The gear ring 601 meshes with a gear 602, and a rotating shaft 603 is fixedly connected to the gear 602. One end of the rotating shaft 603 is rotatably connected to the side wall of the housing 1 through a bearing. A bearing seat 604 is rotatably connected to the rotating shaft 603, and the bearing seat 604 is fixedly connected to the inner bottom wall of the housing 1 by screws.

[0020] The turbulence mechanism 7 includes a motor 701, which is fixedly connected to one side of the housing 1 by screws. The output end of the motor 701 extends into the housing 1 and is fixedly connected to a fan blade 702. The motor 701 drives the fan blade 702 to rotate, thereby accelerating the airflow in the housing 1 and enabling the salt spray to be distributed more evenly within the housing 1. A drive pulley 703 is fixedly connected to the output end of the motor 701. A driven pulley 704 is connected to the drive pulley 703 via a belt. The driven pulley 704 is fixedly connected to the rotating shaft 603. The motor 701 drives the rotating shaft 603 to rotate through the drive pulley 703 and the driven pulley 704. The rotating shaft 603 drives the gear ring 601 to rotate through the gear 602. The gear ring 601 drives the rotating ring 402 to rotate, thereby causing the chip to move in a circular motion within the housing 1.

[0021] The spraying mechanism 2 includes a liquid storage tank 201, which is fixedly connected to the top of the box body 1 by screws. A water pump 202 is fixed inside the liquid storage tank 201. The water outlet of the water pump 202 is connected to a delivery pipe 203. Multiple nozzles 204 are fixed at the bottom of the delivery pipe 203.

[0022] The waste liquid collection mechanism 3 includes a waste liquid tank 301, which is fixedly connected to the bottom of the tank body 1. The bottom wall of the tank body 1 has a slot corresponding to the waste liquid tank 301. A filter screen 302 is inserted into the waste liquid tank 301, and a drain pipe 303 is fixedly connected to one side of the waste liquid tank 301.

[0023] Working principle: During use, the chip is placed inside the carrier mesh plate 501, and the mesh cover plate 502 is placed on top. Then, the locking bolt 503 is rotated to lock the mesh cover plate 502, which presses down on the chip, thus fixing the chip between the carrier mesh plate 501 and the mesh cover plate 502. The carrier mesh plate 501 is inserted into the guide rail 403, and the chamber door is closed. The water pump 202 sends the salt spray test liquid in the storage tank 201 into the infusion pipe 203, and then sprays it out through the nozzle 204. The motor 701 drives the fan blade 702 to rotate, which accelerates the airflow inside the chamber 1, making the salt spray distribution more uniform. At the same time, the motor 701 drives the drive pulley 703 to rotate, actively... The pulley 703 drives the driven pulley 704 to rotate via a belt. The driven pulley 704 drives the rotating shaft 603 to rotate, the rotating shaft 603 drives the gear 602 to rotate, the gear 602 drives the gear ring 601 to rotate, the gear ring 601 drives the rotating ring 402 to rotate, the rotating ring 402 drives the guide rail 403 to rotate, and the guide rail 403 drives the carrier mesh plate 501 to move. This causes the chip to move in a circular motion within the housing 1, allowing the chip to contact the salt spray evenly, thereby improving the accuracy of the detection. After being filtered by the filter screen 302, the salt spray liquid flows into the waste liquid tank 301 for easy recycling. The filter screen 302 can be removed from the waste liquid tank 301 to clean the impurities on the filter screen 302.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
