Description

Technical Field

[0001] The present invention belongs to the technical field of shrapnel detection, and specifically refers to a shrapnel detector. Background Art

[0002] Some shrapnel for special purposes, such as those used in electronic connectors, switches, relays, etc., usually need to have good corrosion resistance to maintain good electrical conductivity and mechanical elasticity. If the surface is oxidized or corroded, it may lead to an increase in contact resistance, a decrease in elastic performance, and a shortening of service life. Therefore, it is necessary to detect the corrosion resistance of shrapnel.

[0003] Existing shrapnel corrosion resistance detection devices mostly use salt spray test chambers. When conducting salt spray tests on shrapnel specimens inside the salt spray test chamber, the specimens are spread on a mesh plate. If the specimens are not dispersed thoroughly enough, there is an easy problem of mutual occlusion. Moreover, most of the salt spray settles downward along the upper direction of the salt spray test chamber. During the downward settlement of the salt spray, it adheres to the surface of the shrapnel specimens for simulation experiments. However, due to being blocked below, the amount of salt spray settlement and adhesion on the upper part of the specimens is greater than that on the lower part of the specimens, thus affecting the test results of the specimens; Salt spray tests require the salt spray to settle evenly on the surface of the specimens to ensure the accuracy of corrosion resistance tests. However, due to the irregular geometric structure of shrapnel with complex shapes, there are easy occlusion problems in grooves or slit areas, resulting in uneven salt spray distribution. This not only affects the uniformity of corrosion but may also cause some areas to corrode faster due to excessive salt spray concentration, thus affecting the reliability of test results; In addition, the salt spray environment will accelerate the corrosion of electrical components, which also adds difficulties to the improvement of shrapnel detectors. Summary of the Invention

[0004] In view of the above situation, to overcome the defects of the prior art, the present invention provides a shrapnel detector that independently places shrapnel specimens and flips and tilts the shrapnel specimens during the detection process to ensure that the salt spray settles evenly on the surface of the shrapnel specimens, improving the reliability of test results.

[0005] The technical solution adopted by the present invention is as follows: A shrapnel detector provided by the present invention includes a salt spray test chamber body. The salt spray test chamber body is provided with a detection cavity with an opening at the upper part. A box cover is hinged above the detection cavity.

A clamping drive one that reciprocates along the Y-axis direction and a clamping drive two that reciprocates along the X-axis direction are arranged at the bottom end of the detection cavity. A specimen rack is arranged on the placing rack, and the specimen racks are symmetrically arranged on both sides of the spray tower; the specimen rack includes a placing cross bar vertically arranged on the two placing racks and adjustable material placing devices arranged at equal intervals along the upper wall of the placing cross bar; the adjustable material placing device includes a fixed frame, an alignment ball, a support column and a material placing basket.

An alignment column is arranged on the side wall of the alignment ball to rotate radially. The axis of the alignment column is perpendicular to the first axis. The first alignment component is connected to the alignment ball through the alignment column and drives the alignment ball to rotate around the first axis. An arc-shaped chute symmetrically extending from the first axis to both sides is arranged on the side wall of the alignment ball along the spherical surface. The axis of the arc-shaped chute is perpendicular to the first axis. The arc-shaped chute is arranged on the side of the alignment ball away from the first alignment component. The second axis passes through the center of the arc-shaped chute. The end of the second alignment component is provided with an alignment sliding shaft slidably connected to the arc-shaped chute.

[0007] Preferably, the first steering assembly comprises a rotating frame, a rotating shaft, a steering gear and a steering slide bar. The rotating shaft is arranged along the first axis direction.

The steering gear is coaxially fixed with the rotating shaft. A sliding frame is fixedly connected to the side wall of the fixed frame along the Y axis direction. The steering slide bar is arranged in an inverted L shape. The axial direction slide is penetrated in the slide frame, and the side wall of the adjustment slide rod is provided with a rack 1 meshing with the adjustment gear 1. The adjustment slide rod is connected to the snap-on drive 1 for transmission. The snap-on drive 1 drives the adjustment slide rod 1 to move back and forth along the Y-axis direction, so that the adjustment slide rod 1 drives the adjustment gear 1 to rotate back and forth through the rack 1, and the adjustment gear 1 drives the rotating frame 1 to rotate back and forth around the first axis through the rotating shaft 1. The rotating frame drives the adjustment ball to rotate back and forth around the first axis through the adjustment column, and the adjustment ball drives the storage basket to rotate around the first axis to adjust the front and rear tilt angles.

[0008] More specifically, the second direction adjustment component includes a second rotating frame, a second rotating shaft, a second direction adjustment gear and a second direction adjustment slide bar. The second rotating shaft is arranged along the second axial direction. The second rotating frame is rotatably arranged at the end of the fixed frame away from the first rotating shaft through the second rotating shaft. The second rotating frame is arranged in an L shape. The direction adjustment slide shaft is connected to the end of the second rotating frame away from the second rotating shaft.

The second snap-on drive drives the second steering slide rod to move back and forth along the X-axis direction, so that the second steering slide rod drives the second steering gear to rotate back and forth through the second rack. The second steering gear drives the second rotating frame to rotate back and forth around the second axis through the second rotating shaft. The second rotating frame drives the steering ball to rotate back and forth around the steering column through the steering sliding shaft. The steering ball drives the storage basket to rotate around the second axis to adjust the left and right tilt angles. The arc-shaped slide groove can ensure that the adjustment of the front and rear tilt angles and the left and right tilt angles of the storage basket are independent of each other and do not affect each other.

[0009] Furthermore, the placement rack is provided with a plurality of placement slots distributed from the middle to both sides, and the placement cross bar is clamped in the placement slots of the placement racks on both sides, and both sides of the placement cross bar are in contact with the inner wall of the detection cavity, so that the placement slots and the inner wall of the detection cavity limit the horizontal movement of the placement cross bar, making it unable to move and only able to move up and down.

[0010] As a further improvement of this solution, the sample holder further includes a first connecting rod and a second connecting rod arranged along the length direction of the placement cross bar.

[0011] The first clamping type drive drives multiple groups of first adjusting slide rods to move synchronously through the first clamping rod and the first connecting rod, thereby driving multiple groups of first adjusting components to drive the adjusting ball to rotate around the first axis. The adjusting ball drives the storage basket to rotate around the first axis to adjust the front-back inclination angle. The second clamping type drive drives multiple groups of second adjusting slide rods to move synchronously through the second clamping rod and the second connecting rod, thereby driving multiple groups of second adjusting components to drive the adjusting ball to rotate around the second axis. The adjusting ball drives the storage basket to rotate around the second axis to adjust the left-right inclination angle.

[0012] Furthermore, the storage basket is arranged in an inverted isosceles triangle shape. The angle of the bottom end included angle of the storage basket is less than or equal to 90°. The upper wall of the storage basket is hollowly arranged. Oblique baffles are symmetrically arranged on both sides of the upper wall of the storage basket. The oblique baffles block the elastic sheet samples to prevent the samples from falling when they flip.

[0013] Among them, the first clamping type drive includes a first slide plate and an adjustable reciprocating motor one that drives the first slide plate to reciprocate along the Y-axis direction. A drive support one is provided on the side wall of the detection cavity. The adjustable reciprocating motor one is arranged on the drive support one. The first slide plate is arranged above the adjustable reciprocating motor one. The first slide plate is provided with a first clamping groove corresponding to each first clamping rod. The first clamping rod is slidably inserted into the first clamping groove. The second clamping type drive includes a second slide plate and an adjustable reciprocating motor two that drives the second slide plate to reciprocate along the X-axis direction. A drive support two is provided on the side wall of the detection cavity. The adjustable reciprocating motor two is arranged on the drive support two. The second slide plate is arranged above the adjustable reciprocating motor two. The second slide plate is provided with a second clamping groove corresponding to each second clamping rod. The second clamping rod is slidably inserted into the second clamping groove.

[0014] Further, the first adjustable reciprocating motor includes an anti-corrosion and heat-insulating housing, a driving motor, a rotating rod, a reciprocating swing rod, a reciprocating sliding rod, an electric push rod, and an adjusting slide plate. The anti-corrosion and heat-insulating housing is arranged at the end of the first driving bracket. From inside to outside, the anti-corrosion and heat-insulating housing is successively provided with a driving cavity and a water-cooling cavity. The water-cooling cavity is communicated with a water-cooling pipe, and the water-cooling pipe is communicated with a water-cooling circulation system. The electric push rod is arranged in the driving cavity, and the adjusting slide plate is arranged at the movable end of the electric push rod. The adjusting slide plate is slidably arranged in the driving cavity, and the electric push rod drives the adjusting slide plate to move up and down. A support plate is arranged on the upper wall of the adjusting slide plate. Along the length direction from top to bottom, a pushing slide hole, a swinging rotating shaft, and a swinging slide hole are successively arranged on the side wall of the reciprocating swing rod. The reciprocating swing rod is rotatably arranged on one side of the support plate through the swinging rotating shaft. The driving motor is arranged on the adjusting slide plate. One end of the rotating rod is connected to the output shaft of the driving motor, and a shifting shaft is arranged at the other end of the rotating rod. The shifting shaft is slidably clamped in the swinging slide hole. A reciprocating slide hole is arranged on the upper wall of the anti-corrosion and heat-insulating housing, and the reciprocating slide hole is communicated with the driving cavity. The upper end of the reciprocating sliding rod is slidably clamped in the reciprocating slide hole, and the lower end of the reciprocating sliding rod is arranged in the driving cavity. An avoidance groove is formed through the reciprocating sliding rod from front to back. A clamping shaft is rotatably connected to the bottom end of the reciprocating sliding rod. The upper end of the reciprocating swing rod is arranged in the avoidance groove, and the clamping shaft is slidably clamped in the pushing slide hole. The reciprocating sliding rod is fixedly installed on the bottom wall of the first slide plate. The second adjustable reciprocating motor has the same structure as the first adjustable reciprocating motor, and the second adjustable reciprocating motor is arranged at a 90° rotation relative to the first adjustable reciprocating motor.

[0015] More specifically, drain holes are equidistantly distributed at the bottom corners of the storage basket. An inverted V-shaped protrusion is arranged between adjacent two groups of the drain holes. An inclined guide part is arranged between the drain holes and the side wall of the storage basket. The drain holes are convenient for discharging the stagnant liquid at the bottom corners of the storage basket. The inverted V-shaped protrusion and the inclined guide part are convenient for guiding the water liquid to the drain holes, effectively avoiding the accumulation of salt liquid.

[0016] The beneficial effects achieved by the present invention with the above structure are as follows: 1. The adjustable feeding device can respectively adjust the front-back inclination angle and the left-right inclination angle of the storage basket. Through the periodic alternating inclination of the storage basket back and forth, the shrapnel specimen is driven to periodically turn over, so as to facilitate ensuring the uniform settlement of the salt mist on the surface of the specimen. By adjusting the left-right inclination angle of the storage basket, the shrapnel specimen contacts the salt mist at different angles, which is convenient for the shrapnel specimen with a complex shape to contact the salt mist more uniformly. At the same time, when the shrapnel is inclined, the stagnant liquid on the surface will automatically slide down under the action of gravity.

[0017] 2. The storage basket is set as an inverted isosceles right triangle. When the storage basket tilts in different directions, the shrapnel specimen can be automatically flipped downward, so that different sides of the specimen are exposed upward. And whether it tilts forward or backward, when the right-angled side on the upper part of the storage basket is adjusted to be approximately vertical, the right-angled side on the lower side is approximately horizontal, which can make the shrapnel specimen placed approximately horizontally, effectively avoiding the occlusion of the side wall of the storage basket above the shrapnel specimen and ensuring uniform sedimentation of salt spray.

[0018] 3. Connect multiple link rods one through a slide plate one, and the link rods one connect multiple first alignment components. Thus, only one drive source is needed to drive multiple first alignment components to act synchronously, so that multiple groups of storage baskets rotate synchronously around the first axis to adjust the front and back tilt angles. At the same time, connect multiple link rods two through a slide plate two, and the link rods two connect multiple second alignment components. Thus, only one drive source is needed to drive multiple second alignment components to act synchronously, so that multiple groups of storage baskets rotate synchronously around the second axis to adjust the left and right tilt angles, greatly reducing the number of drive sources, thereby reducing production and maintenance costs. And the drive motor is placed in an anti-corrosion and heat-insulating housing to reduce the influence of the salt spray environment on the drive motor and extend the service life of the device.

[0019] 4. The first alignment component and the second alignment component cooperate with the alignment ball, which is convenient for driving the storage basket to rotate and tilt in multiple directions. The alignment columns and arc-shaped chutes on the side wall of the alignment ball, in cooperation with the first alignment component and the second alignment component, can ensure that the adjustment of the front and back tilt angles and the adjustment of the left and right tilt angles of the storage basket are independent of each other and do not affect each other.

[0020] 5. Drive the reciprocating swing rod to swing reciprocally through a rotating rod, thereby realizing reciprocating movement, adjusting the distance between the swing rotating shaft and the clamping shaft, and thus adjusting the sliding distance of the reciprocating sliding rod, and further adjusting the left and right tilt angles of the storage basket to facilitate meeting different detection requirements.

[0021] 6. The shrapnel specimen is independently placed through the storage basket to avoid occlusion. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] As Figure 1 , Figures 4 - 14 shown, the adjustable reciprocating motor one 41 includes an anti - corrosion and heat - preservation housing 47, a drive motor 48, a rotating rod 49, a reciprocating swing rod 50, a reciprocating slide rod 51, an electric push rod 52 and an adjustment slide plate 53. The anti - corrosion and heat - preservation housing 47 is arranged at the end of the drive support one 40. From the inside to the outside, the anti - corrosion and heat - preservation housing 47 is provided with a drive cavity and a water - cooling cavity in sequence. The water - cooling cavity is communicated with a water - cooling pipe 65. The water - cooling pipe 65 is communicated with a water - cooling circulation system 66. The water - cooling circulation system 66 is a prior art and will not be elaborated here. The water - cooling circulation system 66 dissipates heat from the drive motor 48 through the water - cooling pipe 65 and the water - cooling cavity. The electric push rod 52 is arranged in the drive cavity. The adjustment slide plate 53 is arranged at the movable end of the electric push rod 52. The adjustment slide plate 53 is slidably arranged in the drive cavity. The electric push rod 52 drives the adjustment slide plate 53 to move up and down. A support plate 54 is provided on the upper wall of the adjustment slide plate 53. Along the length direction from top to bottom on the side wall of the reciprocating swing rod 50, there are a pushing slide hole 55, a swinging rotating shaft 56 and a swinging slide hole 57 in sequence. The reciprocating swing rod 50 is rotatably arranged on one side of the support plate 54 through the swinging rotating shaft 56. The drive motor 48 is arranged on the adjustment slide plate 53. One end of the rotating rod 49 is connected to the output shaft of the drive motor 48. The other end of the rotating rod 49 is provided with a dial shaft 58. The dial shaft 58 is slidably clamped in the swinging slide hole 57. A reciprocating slide hole 59 is provided on the upper wall of the anti - corrosion and heat - preservation housing 47. The reciprocating slide hole 59 is communicated with the drive cavity. The upper end of the reciprocating slide rod 51 is slidably clamped in the reciprocating slide hole 59. The lower end of the reciprocating slide rod 51 is arranged in the drive cavity. An avoidance groove is provided through the reciprocating slide rod 51 from front to back. The bottom end of the reciprocating slide rod 51 is rotatably connected with a clamping shaft 60. The upper end of the reciprocating swing rod 50 is arranged in the avoidance groove. The clamping shaft 60 is slidably clamped in the pushing slide hole 55. The reciprocating slide rod 51 is fixedly installed on the bottom wall of the slide plate one 39. The adjustable reciprocating motor two 44 has the same structure as the adjustable reciprocating motor one 41. The adjustable reciprocating motor two 44 is arranged relatively to the adjustable reciprocating motor one 41 by rotating 90°.

[0036] As Figure 8 and Figure 11 shown, drainage holes 61 are equidistantly distributed at the bottom corner of the storage basket 15. An inverted V-shaped protrusion 62 is provided between two adjacent groups of drainage holes 61. An inclined guide part 63 is provided between the drainage holes 61 and the side wall of the storage basket 15. The drainage holes 61 facilitate the discharge of the stagnant liquid at the bottom corner of the storage basket 15. The inverted V-shaped protrusion 62 and the inclined guide part 63 facilitate the diversion of the water liquid to the drainage holes 61, effectively avoiding the retention and accumulation of salt liquid.

[0037] Referring to Figures 1 - 13 , a controller 64 is provided outside the salt spray test chamber body 1. The controller 64 is electrically connected to the drive motors 48 and the electric push rods 52 of the adjustable reciprocating motor 41 and the adjustable reciprocating motor 44 respectively.

[0038] During specific use, add water to the salt spray test chamber body 1 for debugging and add sodium chloride solution. Then, place the shrapnel specimens one by one into the storage basket 15, with one shrapnel specimen placed in each storage basket 15, and keep the shrapnel specimen in contact with one side of the storage basket 15. After the placement is completed, open the box cover 3, place the specimen rack 9 on the two placement racks 6, insert the placement crossbar 10 into the placement card slot 18, insert the first clamping rod 37 into the first clamping slot 42, and insert the second clamping rod 38 into the second clamping slot 46. The placement card slot 18 and the inner wall of the detection chamber 2 limit the horizontal movement of the placement crossbar 10, making it unable to move horizontally and only able to move up and down. Specifically, during operation, the specimen rack 9 can also be first clamped onto the placement rack 6, and then the shrapnel specimens are placed into the storage basket 15. After the specimens are placed, start the salt spray test chamber body 1 to start the test for corrosion resistance detection. In the initial state, the rotating rod 49 of the adjustable reciprocating motor 41 is horizontally arranged, the support column 14 and the storage basket 15 are inclined forward or backward, the right-angled side of the storage basket 15 on the upper side is slightly inclined to one side, the right-angled side of the storage basket 15 on the lower side is slightly inclined obliquely downward and approximately horizontal, and the shrapnel specimen fits against the right-angled side of the storage basket 15 on the lower side under the action of gravity. At this time, the shrapnel specimen is also approximately horizontal, and the salt spray settles above the shrapnel specimen. The controller 64 controls the clamping drive 7 to trigger actions at a fixed time interval T1 as a cycle and controls the clamping drive 8 to trigger actions at a fixed time interval T2 as a cycle. Each time the clamping drive 7 acts, the controller 64 controls the drive motor 48 of the adjustable reciprocating motor 41 to rotate 180°. When the drive motor 48 rotates 180°, it drives the rotating rod 49 to rotate 180° around the output shaft of the drive motor 48. The rotating rod 49 drives the bottom end of the reciprocating swing rod 50 to rotate from one side of the support plate 54 to the other side through the dial shaft 58 and the swing slide hole 57. Thus, the reciprocating swing rod 50 drives the reciprocating slide rod 51 to move from one side of the reciprocating slide hole 59 to the other side through the push slide hole 55 and the clamping shaft 60. The reciprocating slide rod 51 drives the slide plate 39 to slide forward (backward). The slide plate 39 drives the connecting rod 34 to slide forward (backward) through the first clamping rod 37. The connecting rod 34 drives multiple groups of alignment slide rods 25 to slide forward (backward). The alignment slide rod 25 drives the alignment gear 24 to rotate through the rack 27. The alignment gear 24 drives the rotating frame 22 to rotate around the first axis through the rotating shaft 23. The rotating frame 22 drives the alignment ball 13 to rotate around the first axis through the alignment column 19. The alignment ball 13 drives the storage basket 15 to rotate and tilt to the other side. Each time the storage basket 15 rotates, the rotation angle is slightly larger than the angle between the storage baskets. In this embodiment, each time the storage basket 15 rotates, the rotation angle is slightly larger than 90°, so that the right-angled side of the storage basket 15 on the upper side is slightly inclined to one side, the right-angled side of the storage basket 15 on the lower side is slightly inclined obliquely downward and approximately horizontal, and the shrapnel specimen also automatically flips during the rotation of the storage basket 15, so that the bottom edge of the shrapnel specimen is exposed, facilitating the settlement of the salt spray. By periodically rotating the drive motor 48 of the adjustable reciprocating motor 41 by 180°,Drive the storage basket 15 to tilt periodically back and forth, causing the two sides of the shrapnel specimen to face upward alternately, so as to facilitate ensuring the uniform settlement of salt spray on the specimen surface. Each time the snap-on drive two 8 acts, the controller 64 controls the drive motor 48 of the adjustable reciprocating motor two 44 to rotate 90°. Every four actions of the snap-on drive two 8 in one cycle, the rotating rod 49 of the adjustable reciprocating motor two 44 rotates one circle. The rotating rod 49 drives the bottom end of the reciprocating swing rod 50 to swing back and forth once through the dial shaft 58 and the swing slide hole 57. Thus, the reciprocating swing rod 50 drives the reciprocating slide rod 51 to slide left and right reciprocally once through the push slide hole 55 and the clamping shaft 60. The reciprocating slide rod 51 of the adjustable reciprocating motor two 44 drives the slide plate two 43 to slide left and right reciprocally once. The slide plate two 43 drives the link two 35 to slide left and right reciprocally once through the second clamping rod 38. The link two 35 drives multiple groups of the adjustable guide rods two 31 to slide left and right reciprocally through the adjustable guide rod two 31. The adjustable guide rod two 31 drives the adjustable gear two 30 to rotate through the rack two 33. The adjustable gear two 30 drives the rotating frame two 28 to rotate around the second axis through the rotating shaft two 29. The rotating frame two 28 drives the adjustable ball 13 to rotate reciprocally around the adjustable column 19 once through the adjustable guide shaft 21. The adjustable ball 13 drives the storage basket 15 to rotate reciprocally around the second axis once. During this process, the storage basket 15 changes in the X-axis direction from vertical - tilted to the left - vertical - tilted to the right - vertical. The arc-shaped slide groove 20 can ensure that the adjustment of the front-back tilt angle and the left-right tilt angle of the storage basket 15 are independent of each other and do not affect each other. By tilting the storage basket 15 left and right, the shrapnel specimen contacts the salt spray at different angles, facilitating the more uniform contact of the shrapnel specimen with complex shapes with the salt spray. At the same time, when the shrapnel is tilted, the retention liquid on the surface will automatically slide off under the action of gravity.

[0039] In this embodiment, in one cycle period of the snap-on drive one 7, the snap-on drive two 8 can be set to act periodically and intermittently four times. During this period, the storage basket 15 maintains a state of tilting forward or backward. The storage basket 15 changes in the X-axis direction from vertical - tilted to the left - vertical - tilted to the right - vertical, making the settlement of the salt spray more uniform.

[0040] During use, the controller 64 can be used to control the telescopic movement of the electric push rod 52, thereby driving the adjustment slide plate 53 to move up and down in the drive cavity, adjusting the distance between the swing rotating shaft 56 and the clamping shaft 60, and thus adjusting the sliding distance of the reciprocating slide rod 51. The smaller the distance between the swing rotating shaft 56 and the clamping shaft 60, the smaller the sliding distance of the reciprocating slide rod 51, the smaller the sliding distance of the slide plate one 39 (slide plate two 43), the smaller the sliding distance of the rack one 27 (rack two 33), the smaller the rotation angle of the adjustable gear one 24 (adjustable gear two 30) driving the adjustable ball 13, and the smaller the tilt angle of the storage basket 15. Conversely, the larger the tilt angle of the storage basket 15.
