Description

Technical Field

[0001] The invention relates to the technical field of watch detection, and in particular to a watch strap corrosion resistance detection device. Background Art

[0002] The salt spray test machine is a device specially used to simulate the salt spray environment to test the corrosion resistance of materials or products. It generates salt mist in a closed test chamber by spraying. The mist contains a certain proportion of salt solution, usually imitating the salt spray climate in the marine environment. This test is widely used in the fields of navigation, electronics and watch manufacturing to ensure the long-term reliability and weather resistance of the product.

[0003] Although the existing salt spray test machine can simulate the situation of seawater corroding the watch strap, when people wear watches on the beach, there are sand and stone particles between the strap and the skin. Under the condition of seawater corrosion, there is also the factor of sand and stone particles wearing the strap. When performing salt spray testing on the watch strap, the existing salt spray test machine can only simply simulate the situation of seawater corroding the watch strap, and cannot create the conditions for sand and stone particles to wear the watch strap on this basis. Further, it cannot truly simulate the impact of seawater and sand and stone particles on the watch strap when people wear watches on the beach, thereby reducing the authenticity of the watch strap detection.

[0004] Furthermore, in order to facilitate real-time monitoring of strap corrosion and shorten the feedback cycle of strap detection, some salt spray testers are equipped with cameras for monitoring. However, the existing salt spray testers use an atomization method to create a salt spray environment, so that there is a large amount of salt-containing mist in the test area. When the camera is monitoring, the salt mist condenses on the camera lens, resulting in blurred vision and affecting the observation effect. Summary of the invention

[0005] In order to overcome the disadvantage that the existing salt spray test machine cannot truly simulate the impact of seawater and sand particles on the watch strap when a person wears a watch on the beach, thereby reducing the authenticity of the watch strap detection, the present invention provides a watch strap corrosion resistance detection device.

DETAILED DESCRIPTION

[0029] The following descriptions are merely preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.

[0030] Example 1

[0031] like Figure 1-Figure 8 As shown, a strap corrosion resistance detection device includes a testing machine 1 and a machine cover 2; the testing machine 1 is rotatably connected to the machine cover 2; the testing machine 1 is provided with a sprayer 1001; the testing machine 1 is provided with a water storage tank 1002;

[0032] It also includes a limit assembly, a fixed tube 3, a monitoring assembly, an annular lens 4 and a locking rod 5; a limit assembly is arranged on the testing machine 1; a plurality of fixed tubes 3 are detachably connected to the limit assembly; a plurality of frosted rods 3001 are arranged on each fixed tube 3; a monitoring assembly is arranged in each fixed tube 3; a plurality of viewing windows 3002 are opened on each fixed tube 3; a plurality of annular lenses 4 are rotatably connected in each fixed tube 3; each viewing window 3002 is located on the outside of the annular lens 4; each annular lens 4 is provided with two locking rods 5 which are symmetrical in front and back; a plurality of avoidance grooves 3006 are opened on each fixed tube 3; each locking rod 5 penetrates the fixed tube 3 and slides in the corresponding avoidance groove 3006.

[0033] The limiting assembly includes a DD motor 101, a fixed block 102 and a limiting rod 103; a plurality of DD motors 101 are fixedly connected to the testing machine 1; a plurality of fixed blocks 102 that are symmetrical in front and back are rotatably connected to the testing machine 1; each fixed block 102 located on the front side is fixedly connected to the corresponding output end of the DD motor 101; each fixed tube 3 is detachably connected to two fixed blocks 102 opposite to each other in the front and back; a plurality of limiting rods 103 are fixedly connected inside the testing machine 1; each two adjacent limiting rods 103 are located below the corresponding fixed tube 3.

[0034] The monitoring assembly includes a fixed rod 201 and a camera 202 ; a fixed rod 201 is fixedly connected in each fixed tube 3 ; a plurality of cameras 202 are fixedly connected to each fixed rod 201 ; and each camera 202 faces a corresponding window 3002 .

[0035] Furthermore, in order to ensure the friction effect of the frosted rod 3001 on the strap while making the frosted rod 3001 avoid the protruding parts on the strap to prevent abnormal scratches on the protruding parts on the strap, each frosted rod 3001 is arranged in a convex arc shape toward the side of the strap.

[0036] Each window 3002 is provided with two guide portions 3003 which are symmetrical in vertical direction; each guide portion 3003 is provided in a herringbone shape.

[0037] It also includes a baffle 6; each fixed tube 3 is provided with a plurality of sliding grooves 3004; a baffle 6 is slidably connected in each of two adjacent sliding grooves 3004; each baffle 6 is detachably connected with a Velcro hook surface on one side facing the center of the fixed tube 3; and a plurality of locking rods 6001 are provided on the lower side of each baffle 6.

[0038] Each baffle 6 is provided with two blocking portions 6002 which are symmetrical with respect to each other.

[0039] The cover 2 also includes a baffle 7 ; the baffle 7 is fixedly connected to the lower portion of the inner wall of the cover 2 .

[0040] The present invention grinds the watch strap by means of the grinding rod 3001 on the basis of the salt spray test on the watch strap, thereby solving the problem that the existing salt spray test machine can only simulate the situation that the sea water corrodes the watch strap, but cannot simulate the situation that the sand and stone particles wear the watch strap on this basis, and thus cannot truly simulate the influence of the sea water and sand and stone particles on the watch strap when a person wears a watch on the beach, thereby reducing the authenticity of the watch strap detection. The specific process is as follows:

[0041] Before testing the cloth strap of the watch, the staff first fixes the strap around the fixing tube 3, and makes the inner ring surface of the strap after being fixed fit with the frosted rod 3001, and makes the watch case fit with the lower side of the baffle 6. Then the staff places the fixing tube 3 with the strap fixed in the testing machine 1, and makes the two ends of the fixing tube 3 respectively snap into the corresponding fixing blocks 102, and makes the locking rod 5 snap into the two limit rods 103, which is used to limit and fix the annular lens 4, and makes the watch case snap downward between the two limit rods 103 for limit and fixation. In this process, the locking rod 6001 on the baffle 6 is snapped into the two limit rods 103 together with the watch case for limit and fixation, which is used to limit and fix the baffle 6. After the fixing tube 3 is placed, the staff closes the machine cover 2. Figure 3 As shown, the lower part of the cover 2 is fitted into the water tank 1002, and water is added to the water tank 1002 to enhance the sealing effect of the cover 2 and prevent the leakage of salt mist. After the cover 2 is closed, the baffle 7 is fitted to the inner edge of the upper side of the test machine 1, and then the sprayer 1001 is controlled to spray the salt mist into the test machine 1, and the salt spray test of the cloth watch strap of the watch is started. During the test, the salt mist adheres to the inner wall of the cover 2 and flows downward. The baffle 7 blocks the salt water flowing downward along the inner wall of the cover 2, so that the salt water flows into the test machine 1, and prevents the salt water from flowing into the water tank 1002 along the inner wall of the cover 2, so as to avoid the edge of the cover 2 from being in contact with the salt water flowing into the water tank 1002 for a long time and causing corrosion, thereby ensuring the sealing performance and service life of the equipment.

[0042] When the cloth watch strap is subjected to a salt spray test, the DD motor 101 is controlled to drive the fixed block 102 to rotate back and forth, thereby driving the fixed tube 3 to rotate back and forth. Since the watch case is limited by the limit rod 103 and cannot rotate back and forth with the fixed tube 3, the fixed tube 3 rotates relatively to the watch. The inner ring surface of the watch strap is polished by the frosting rod 3001 on the fixed tube 3 on the basis of the salt spray test of the watch strap. This is conducive to simulating the impact of sea water and sand particles on the watch strap when a person wears a watch on the beach. It can be closer to the actual wearing conditions, better evaluate and verify the wear resistance and corrosion resistance of the cloth watch strap, and improve the authenticity of the watch strap detection.

[0043] When the fixed tube 3 reciprocates to rub the watch strap, the camera 202 rotates with the fixed tube 3 through the fixed rod 201. The camera 202 arranged inside the fixed tube 3 monitors the wear and corrosion of the watch strap in real time from the window 3002 through the annular lens 4 during the rotation process. This is conducive to shortening the feedback cycle of the watch strap detection, optimizing the test efficiency, and ensuring the accuracy and reliability of the test data. However, considering that the interior of the test machine 1 is a salt spray environment, the salt spray is easy to adhere to the outside of the annular lens 4, resulting in the camera 202 being unable to observe the corrosion of the watch strap normally through the annular lens 4. At this time, the locking rod 5 is used to lock the camera 202. The annular lens 4 is driven to be stuck between the two limit rods 103, and the annular lens 4 is limited and fixed. When the fixed tube 3 reciprocates, the locking rod 5 slides in the avoidance groove 3006 relative to the fixed tube 3, so that the annular lens 4 cannot rotate together with the fixed tube 3, so that the fixed tube 3 rotates relatively to the annular lens 4, and then the annular lens 4 located in the window 3002 is continuously changed, and the salt mist adhered to the annular lens 4 is scraped off through the window 3002, so that the overlapping part of the window 3002 and the annular lens 4 is always kept in a clear state, ensuring that the camera 202 can clearly monitor the corrosion of the strap in real time.

[0044] While the window 3002 cleans the salt mist adhered to the annular lens 4, the salt water flowing toward the window 3002 on the fixed tube 3 is guided toward the front and rear sides of the window 3002 through the herringbone guiding portion 3003, preventing the condensed salt water on the fixed tube 3 from flowing into the window 3002, thereby preventing the annular lens 4 from being blocked by the salt water, thereby ensuring that the camera 202 can clearly monitor the corrosion of the strap in real time.

[0045] It is also considered that when the fixed tube 3 reciprocates to rub the cloth watchband, the cloth scraps on the watchband adhere to the frosting rod 3001, so that the frosting rod 3001 carries the cloth scraps to rub the watchband, resulting in a gradual decrease in the friction strength of the frosting rod 3001 on the watchband, and the detection accuracy also decreases accordingly. The specific solution process is as follows:

[0046] When the fixed tube 3 reciprocates and drives the frosting rod 3001 to rub the cloth watch strap, the baffle 6 is blocked and limited by the limiting rod 103 through the locking rod 6001. Compared with the fixed tube 3 sliding in the sliding groove 3004, when the frosting rod 3001 carrying the cloth scraps rotates to contact the Velcro hook surface on the upper side of the baffle 6, the Velcro hook surface on the upper side of the baffle 6 adheres to the cloth scraps adhered to the frosting rod 3001, preventing the frosting rod 3001 from carrying the cloth scraps to rub the watch strap, thereby avoiding The friction strength of the frosted rod 3001 on the watch strap is gradually reduced, ensuring the detection accuracy of the watch strap. At the same time, the blocking part 6002 blocks the cloth scraps caused by the friction of the frosted rod 3001 to prevent the cloth scraps from getting stuck in the sliding groove 3004, thereby ensuring the normal sliding of the baffle 6 in the sliding groove 3004. After the corrosion resistance test of the watch strap is completed, the staff first removes the watch strap from the fixing tube 3, and then removes and replaces the Velcro hook surface on the upper side of the baffle 6, preparing for the next test.

[0047] Example 2

[0048] On the basis of Example 1, Figure 3-Figure 5 and Figure 7-Figure 8 As shown, it also includes an extrusion block 301 and a water-absorbing sponge 302; each window 3002 is fixed with two water-absorbing sponges 302 that are symmetrical up and down; each water-absorbing sponge 302 is fitted with the outer side of the annular lens 4; the front side of each baffle 6 is rotatably connected to the extrusion block 301 through a torsion spring.

[0049] Each guide portion 3003 is provided with an avoidance portion 3005 .

[0050] While the window 3002 is cleaning the salt mist adhered to the annular lens 4, the absorbent sponge 302 is driven by the window 3002 to rotate in contact with the outer side of the annular lens 4, so that the absorbent sponge 302 can absorb and clean the salt mist adhered to the outer side of the annular lens 4 in time, thereby enhancing the cleaning effect of the annular lens 4 and further improving the monitoring clarity of the camera 202 through the annular lens 4.

[0051] When the viewing window 3002 rotates with the fixed tube 3, the avoidance portion 3005 first contacts the extrusion block 301. As the fixed tube 3 continues to rotate, the extrusion block 301 moves along the avoidance portion 3005 to the guide portion 3003 and is inserted into the viewing window 3002. As the viewing window 3002 drives the water-absorbing sponge 302 to rotate and contact the extrusion block 301, the water-absorbing sponge 302 is squeezed by the extrusion block 301, so that the salt water absorbed in the water-absorbing sponge 302 flows downward into the testing machine 1, thereby allowing the water-absorbing sponge 302 to always maintain the effect of absorbing and cleaning the salt mist on the outer side of the annular lens 4.
