Description

Technical Field

[0001] The invention relates to the technical field related to film detection, in particular to an ultraviolet rapid aging test box for films. Background Art

[0002] UV aging test chamber is widely used in the testing of various types of membrane materials such as agricultural and industrial membranes, functional protective films, and membranes used in new energy and electronic fields. The necessity of membrane material testing is self-evident, which is used to ensure the performance of membrane materials, make the membrane materials meet the use requirements, and ensure quality and safety. The UV aging test chamber uses fluorescent UV lamps as light sources to simulate UV radiation environments. It detects aging phenomena such as discoloration and embrittlement of membrane materials under long-term UV irradiation. It also detects the stability of membrane materials in alternating warm or dry heat environments by combining condensation and spraying procedures.

[0003] After searching the invention patent with the authorization announcement number CN109916806B, an ultra-strong ultraviolet light aging test chamber is disclosed. The key points of its technical solution are that it includes a box body and a material rack. The material rack includes a movable plate and a placement plate. The placement plate includes a main board and a limit plate. The sample to be tested is placed on the main board. A metal halide lamp is provided on the top of the test chamber, and it also includes a lifting mechanism. The distance between the material rack and the metal halide lamp is adjusted by the lifting mechanism.

[0004] Based on the above patents and combined with existing solutions and actual use processes, the current UV rapid aging test chambers for film testing still have some problems, such as: Some existing UV rapid aging test boxes place test samples by directly placing the film test samples on the sample rack in the box, which is the same as the placement method of the test samples in the above patent, and the test samples are directly placed on the main board in the material rack. However, this placement method is not easy to fix and stabilize the film test samples. In response to the thin and light characteristics of the film material itself, this non-fixed placement method is prone to displacement during detection, affecting the detection effect; Some other existing UV rapid aging test chambers place the test samples in a way that the film test sample is placed in a groove-shaped sample rack, then a sample plate is placed on the film test sample to cover it, and finally the sample plate is limited by an elastic steel ring. However, this placement method cannot achieve the tensioning operation of the film test sample after placement, that is, it cannot ensure the flatness of the illuminated detection surface of the film test sample, and it is easy for the film test sample to cause light differences due to deformation; Therefore, we propose a UV rapid aging test box for membranes to solve the above problems.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] The present invention provides a technical solution: a UV rapid aging test box for membranes, which can solve the problem that when a membrane material test sample is placed, it is difficult to fix and firmly place it, and the tensioning operation after placement cannot be achieved, that is, the flatness of the light-receiving detection surface cannot be guaranteed. The membrane material test sample cannot be evenly lighted due to deformation, which causes light receiving differences and affects the detection effect. The upper and lower ends of a membrane material body 5 are respectively rolled up by upper and lower winding mechanisms 8 to achieve the tensioning and leveling operation of the membrane material body 5. In addition, the membrane material body 5 is fixed and firmly placed on the sample plate rack 4 by clamping the sample clamping plate 6.

[0021] This technical solution: please refer to Figure 1-Figure 10 A film-use ultraviolet rapid aging test box comprises an ultraviolet aging test box body 1, wherein the box cavity of the ultraviolet aging test box body 1 is mainly provided with an ultraviolet light source simulation component and a temperature and humidity control component (the ultraviolet light source simulation component and the temperature and humidity control component are both prior art and are not described in detail in the drawings of the specification), and the box opening of the ultraviolet aging test box body 1 is flipped and connected with an openable and closable box door panel 2, a latch is provided at the middle position of the upper end of the box door panel 2, and the left side board wall of the box door panel 2 is fixedly connected with an external shell 201 which is connected with the shell cavity and the board cavity in the box door panel 2; It also includes a carrying frame 3, which is fixedly connected to the right side wall of the box door panel 2. Sample plate racks 4 are arranged at equal intervals in the frame cavity of the carrying frame 3, and the right side wall of the sample plate rack 4 is clamped with a membrane material body 5 by a sample clamping plate 6, and a locking block 7 for fixing the sample clamping plate 6 is provided at the connection between the sample clamping plate 6 and the sample plate rack 4. The membrane material body 5 is fixed and firmly placed by the sample clamping plate 6. A winding mechanism 8 is provided in the upper and lower storage grooves of the sample plate rack 4. The upper and lower winding mechanisms 8 are respectively used for winding up the upper and lower ends of the membrane material body 5 to perform tensioning and flattening operations on the membrane material body 5.

[0022] Specifically, in this technical solution, the membrane material body 5 is placed on the sample plate rack 4 according to Figure 4 , Figure 7 and Figure 8 As shown, storage grooves are provided in the middle positions of the upper and lower sides of the sample plate rack 4, and winding mechanisms 8 are provided in the upper and lower two storage grooves of the sample plate rack 4. After the winding mechanism 8 is placed, its center is on the same horizontal central axis as the center of the storage groove in the sample plate rack 4. Since the winding mechanism 8 includes a winding rod 11 for winding the membrane material body 5 and a limit seat 12 for braking the winding rod 11, the winding rod 11 is placed in the storage groove in the sample plate rack 4, and since a through long groove portion is provided on the rod body of the winding rod 11, the membrane material body 5 of corresponding specifications and sizes is cut before the test, and the upper and lower ends of the membrane material body 5 are respectively inserted through the long groove portion of the upper winding rod 11 and the long groove portion of the lower winding rod 11, so that the membrane material body 5 is attached to the right side wall of the sample plate rack 4, and the placement of the membrane material body 5 on the sample plate rack 4 is completed.

[0023] Specifically, in this technical solution, the film material body 5 is rolled up by the rolling mechanism 8. Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, since the main end cover 14 is placed in an active state in the rear side wall groove cavity of the storage groove in the sample plate rack 4, and it is clamped and fixedly connected to the rear end of the winding rod 11 by bolts, and since the auxiliary end cover 18 is placed in an active state in the front side wall groove cavity of the storage groove in the sample plate rack 4, and it is movably clamped at the front end of the limit seat 12, two fingers press the main end cover 14 and the auxiliary end cover 18 at the same time, and drive the main end cover 14 and the auxiliary end cover 18 to rotate at the same time. When the auxiliary end cover 18 is driven, the auxiliary end cover 18 rotates at the front end of the limit seat 12 without affecting the limit seat 12; Since the rear end of the winding rod 11 is fixedly connected with the main end cover 14, the two constitute a synchronous rotation structure, and since the front and rear ends of the winding rod 11 are fixedly clamped with bearings, the winding rod 11 is placed in the storage groove in the sample plate rack 4, and its front and rear ends are respectively inserted into the front and rear side walls of the storage groove in the sample plate rack 4 with bearings, and its front and rear ends are respectively inserted into the groove cavities of the front and rear side walls of the storage groove in the sample plate rack 4. Since the long groove portion in the winding rod 11 is connected with the end of the membrane material body 5 in an interlaced manner, and the two are wound and connected together, the main end cover 14 is driven to drive the winding rod 11 to move synchronously, so that the winding rod 11 is wound and rotated in the storage groove in the sample plate rack 4, and the winding operation of the membrane material body 5 is completed. After being wound, the membrane material body 5 is stored in the storage groove in the sample plate rack 4; Since the rotation directions of the upper and lower winding rods 11 in the sample plate rack 4 are opposite, and since the winding direction of the upper end of the membrane material body 5 on the upper winding rod 11 is opposite to the winding direction of the lower end of the membrane material body 5 on the lower winding rod 11, according to the above, the two winding rods 11 are operated in sequence to respectively wind up the upper and lower ends of the membrane material body 5, so as to complete the tensioning and flattening of the membrane material body 5, and ensure that the membrane material body 5 can be evenly exposed to light during the test.

[0024] Specifically, in this technical solution, the winding rod 11 performs a self-locking operation after completing the winding. Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, since the ratchet ring 15 is placed in a movable state in the front side wall groove cavity of the storage groove in the sample plate rack 4, and it is clamped and fixedly connected to the front end of the winding rod 11 by bolts, when the winding rod 11 is wound and rotated, the ratchet ring 15 is driven to rotate synchronously; Since the limit seat 12 is used for braking the winding rod 11, the rear end of the limit seat 12 is an end facing the ratchet ring sleeve 15, and the front end of the limit seat 12 is an end away from the ratchet ring sleeve 15. The longitudinal section of the middle section of the limit seat 12 is a square structure. After being installed, it is movably clamped in the groove cavity of the front side wall of the storage groove in the sample plate rack 4, and its rear end is inserted into the ring cavity of the ratchet ring sleeve 15, so that the limit seat 12 is positioned on the sample plate rack 4 in an active state; Since both sides of the rear end of the limit seat 12 are provided with a pawl member 16 of a square columnar structure, the end of the pawl member 16 facing the limit seat 12 is the pawl tail end, wherein the pawl tail end is provided with a limit disk portion of an integrated structure, and the end of the pawl member 16 away from the limit seat 12 is the pawl head end. After the pawl member 16 is installed, the pawl tail end and the limit disk portion are movably clamped in the groove cavity at the rear end of the limit seat 12, and the pawl head end movably penetrates the groove cavity wall at the rear end of the limit seat 12 and extends outward, so that the pawl member 16 is positioned on the limit seat 12 in an active state. Since the pawl head ends of the left and right pawl members 16 are arranged in opposite directions, a second spring 17 is installed at the sliding connection between the pawl member 16 and the limit seat 12, and the second spring 17 is arranged between the left and right pawl members 16 and placed in the groove cavity at the rear end of the limit seat 12. , one end of which is pressed against the claw tail end of the left pawl member 16, and the other end of which is pressed against the claw tail end of the right pawl member 16. The ratchet ring sleeve 15 is fixedly connected to the front end of the winding rod 11, and rotates synchronously with the winding rotation of the winding rod 11. When the ratchet ring sleeve 15 rotates, the direction of the ratchet in the ratchet ring sleeve 15 is adapted to the rotation and winding direction of the winding rod 11, so that the pawl member 16 slides along the ratchet in the ratchet ring sleeve 15. After being pushed, the pawl member 16 shrinks and slides on the limit seat 12, so that the second spring 17 is squeezed and elastically deformed. When the ratchet ring sleeve 15 rotates, the elastic deformation of the second spring 17 is used to reset, so that the pawl member 16 loses the pushing and extends and slides on the limit seat 12, and the claw head end of the pawl member 16 is connected to the ratchet ring sleeve 15 in a snap-fit ​​manner; Since a first torsion spring 13 is installed at the rotation connection between the rear section of the winding rod 11 and the sample plate rack 4, the first torsion spring 13 is movably sleeved on the rear section rod body of the winding rod 11 after being installed, one end of the first torsion spring 13 is clamped on the rear section rod body of the winding rod 11, and the other end of the first torsion spring 13 is clamped on the rear side wall of the storage groove in the sample plate rack 4. After the winding rod 11 is wound and rotated, the first torsion spring 13 is subjected to force and elastically deformed. Through the elastic deformation reset of the first torsion spring 13 and the clamping action between the pawl 16 and the ratchet ring sleeve 15, the rotated ratchet ring sleeve 15 is locked, that is, the winding rod 11 after winding and rotating is automatically locked.

[0025] Specifically, in this technical solution, the winding rod 11 is unlocked according to Figure 7 and Fig. 9As shown, after the secondary end cover 18 is installed, it is movably clamped at the front end of the limit seat 12, so that the secondary end cover 18 is positioned on the limit seat 12 in an active state, and the two constitute a synchronous sliding structure. Since spring bins are provided on the upper and lower sides of the front section of the limit seat 12, a third spring 19 is installed at the sliding connection between the limit seat 12 and the sample plate rack 4, and the third spring 19 is symmetrically arranged about the horizontal central axis of the limit seat 12. After the third spring 19 is installed, it is movably inserted into the spring bin of the limit seat 12, one end of which presses against the spring bin wall of the limit seat 12, and the other end presses against the groove cavity wall of the front side wall of the storage groove in the sample plate rack 4, pressing the secondary end cover 18, so that the limit seat 12 is unlocked and slid in the groove cavity of the front side wall of the storage groove in the sample plate rack 4, and the third spring 19 is squeezed and elastically deformed. In addition, when the secondary end cover 18 is released from being pressed, the elastic deformation of the third spring 19 is utilized to drive the limit seat 12 to reset and slide; Since an annular groove 1501 is provided in the annular cavity of the ratchet ring sleeve 15 to allow the limit seat 12 to unlock and slide, the diameter of the annular groove 1501 is larger than the spacing between the two pawl members 16 in the extended state, and since a first torsion spring 13 for resetting is installed at the rotational connection between the rear section of the winding rod 11 and the sample plate rack 4, after the limit seat 12 is driven to unlock and slide, the pawl head end of the pawl member 16 loses the engaging connection with the ratchet ring sleeve 15, and the pawl member 16 moves into the annular groove 1501, which does not affect the resetting rotation of the ratchet ring sleeve 15, thereby releasing the lock of the winding rod 11, and then using the elastic deformation of the first torsion spring 13 to reset, the winding rod 11 is unwound and rotated in the storage groove in the sample plate rack 4, completing the unwinding and replacement operation of the membrane material body 5.

[0026] Specifically, in this technical solution, the membrane material body 5 is fixed and firmly placed by the sample clamp 6. Figure 5 and Figure 6 As shown, the right side wall of the sample plate rack 4 is arranged toward the UV aging test box body 1, and empty slots are provided in the middle positions of the front and rear side walls of the sample plate rack 4. Since the middle positions of the front and rear sides of the sample clamping plate 6 are vertically provided with connecting plate parts of an integrated structure, the membrane material body 5 is stretched and flattened to fit on the right side wall of the sample plate rack 4. After the sample clamping plate 6 is placed, two connecting plate parts thereof are respectively inserted into the two empty slots of the sample plate rack 4, and the plate body thereof is clamped on the right side wall of the sample plate rack 4, that is, the membrane material body 5 is clamped on the right side wall of the sample plate rack 4, thereby completing the further fixing and stable placement of the membrane material body 5. Since locking blocks 7 for fixing the sample clamping plate 6 are provided in the front and rear empty grooves of the sample plate rack 4, the cross section of the locking block 7 is in an "L"-shaped structure, which is divided into two parts, a transverse block and a longitudinal block. After the locking block 7 is installed, it is movably clamped in the frame of the sample plate rack 4, wherein the end of the transverse block movably penetrates through the frame of the sample plate rack 4 to extend into the empty groove of the sample plate rack 4, and the end of the longitudinal block movably penetrates the left side wall of the sample plate rack 4 to extend outward, so that the locking block 7 is positioned on the sample plate rack 4 in an active state. Since spring compartments are evenly spaced on the longitudinal blocks in the locking block 7, a first spring 10 is installed at the sliding connection between the sample plate rack 4 and the locking block 7, and the first spring 10 is evenly spaced on the locking block 7. After the first spring 10 is installed, it is movably inserted in the spring compartment in the locking block 7, and one end thereof presses against the locking block 7. The spring bin is on the wall of the spring bin, and the other end thereof is pressed against the frame body of the sample plate rack 4. Since the end of the transverse block in the locking block 7 is in an oblique tongue-shaped structure, wherein the inclined side wall of the oblique tongue end is arranged toward the sample clamping plate 6, when the connecting plate portion in the sample clamping plate 6 is plugged into the empty slot of the sample plate rack 4, the connecting plate portion in the sample clamping plate 6 pushes the oblique tongue end in the locking block 7 through the inclined side wall of the oblique tongue end in the locking block 7, so that the locking block 7 shrinks and slides in the empty slot of the sample plate rack 4, and the first spring 10 is squeezed and elastically deformed. When the connecting plate portion in the sample clamping plate 6 is plugged into the empty slot of the sample plate rack 4, the first spring 10 is reset by elastic deformation, so that the locking block 7 extends and slides in the empty slot of the sample plate rack 4, and the oblique tongue end in the locking block 7 is connected to the connecting plate portion in the sample clamping plate 6 in a snap-fit ​​manner, thereby locking the sample clamping plate 6.

[0027] Specifically, in this technical solution, before the test, the membrane material body 5 is placed on the sample plate rack 4, and the sample plate rack 4 is arranged in the frame cavity of the carrier frame 3 at equal intervals.

The supporting frame 3 is a square frame structure, which is clamped and fixedly connected to the opening of the right side wall of the door panel 2 by bolts after being installed. Since the front end of the supporting frame 3 is provided with a through slot 302 for taking and placing the sample plate rack 4, the through slot 302 is connected to the frame cavity in the supporting frame 3, and the area size of the through slot 302 is larger than the surface size of the sample plate rack 4. The sample plate rack 4 is of a certain size, so that the sample plate rack 4 can freely enter and exit the through-port groove 302. Since the through-port groove 302 is provided with a right side opening facing the outside of the box door plate 2, the right side opening of the through-port groove 302 is provided with a cover plate 9. After the cover plate 9 is placed, it is clamped on the front end of the right side wall of the carrying frame 3. Before arranging the sample plate rack 4, the cover plate 9 is removed from the carrying frame 3 by pulling, so that the right side opening of the through-port groove 302 is not covered, and then the sample plate rack 4 is placed in the frame cavity of the carrying frame 3 through the through-port groove 302; Since the upper and lower frame cavity walls of the carrier frame 3 are horizontally provided with a circular tubular guide groove 301, an opening is provided on one side of the guide groove 301 facing the frame cavity in the carrier frame 3, wherein the width dimension of the opening is smaller than the diameter dimension of the guide groove 301, and since the upper and lower ends of the sample plate holder 4 are clamped and fixedly connected with a circular rod-shaped guide rod portion 401 by bolts, the guide rod portion 401 is arranged in parallel with the sample plate holder 4, and the upper and lower guide rod portions 401 correspond to the upper and lower guide grooves 301 respectively, the sample When the plate rack 4 is arranged on the carrier frame 3, the sample plate rack 4 is movably inserted in the frame cavity of the carrier frame 3, so that the guide rod portion 401 is movably inserted through the opening of the guide groove 301, and the guide rod portion 401 is movably set in the guide groove 301, so that the sample plate rack 4 is arranged in the frame cavity of the carrier frame 3 at equal intervals. After the sample plate rack 4 is arranged, the sample plate rack 4 is positioned in the frame cavity of the carrier frame 3 in an active state, even if the sample plate rack 4 does not detach from the carrier frame 3, and two adjacent sample plate racks 4 are arranged in a close fit state; After the arrangement of the sample plate rack 4 is completed, according to the above, the right side opening of the through-opening groove 302 is re-covered by means of the cover plate 9 which is snapped onto the supporting frame 3. After the cover plate 9 covers the through-opening groove 302, the cover plate 9 is flush with the right side wall of the supporting frame 3, and the cover plate 9 does not hinder the sliding of the sample plate rack 4.

[0028] Specifically, in this technical solution, the film material body 5 is tested by the UV aging test box body 1.

In addition, since the box opening of the ultraviolet aging test box body 1 is turned over and connected with the box door plate 2, the bearing frame 3 is fixedly connected to the right side plate wall of the box door plate 2, and the sample plate racks 4 are arranged at equal intervals on the bearing frame 3, the box door plate 2 is placed on the ultraviolet aging test box body. 1 is flipped and closed, the sample plate rack 4 carries the membrane material body 5 and maintains an adaptive distance with the ultraviolet light source simulation component and the temperature and humidity control component in the ultraviolet aging test box body 1, and is arranged in a parallel state. After the box door panel 2 is flipped and closed, the box door panel 2 and the ultraviolet aging test box body 1 are locked by the lock in the box door panel 2. During the test, the ultraviolet radiation environment is simulated by the ultraviolet light source simulation component, and the warm or dry heat alternating environment is simulated by the temperature and humidity control component, and the rapid aging phenomenon such as discoloration and embrittlement of the test film material is tested; Since two through-shaped sample openings are provided in the middle of the plate body in the sample clamp 6 from top to bottom, the width dimension of the membrane material body 5 is larger than the width dimension of the sample opening in the sample clamp 6. During the test of the membrane material body 5, the ultraviolet light source simulation component and the temperature and humidity control component in the ultraviolet aging test box body 1 pass through the sample opening in the sample clamp 6 to perform rapid aging tests such as discoloration and embrittlement on the membrane material body 5, even if there are two sample points on the membrane material body 5. Example

[0029] The present invention is based on the first embodiment. Figure 11-Figure 17 The technical solution shown in the figure, in the test using the ultraviolet rapid aging test box, in order to make the test samples evenly exposed to the influence of fluorescent ultraviolet light and temperature and humidity, it is necessary to periodically rotate the positions of the test samples to ensure that the test samples receive the same radiation energy. In response to the existing ultraviolet rapid aging test box, after the machine needs to be shut down, the box door needs to be opened to manually rotate the positions of the test samples. This rotation method will cause the test to be interrupted, affecting the continuity and stability of the test, causing distortion of the test data and affecting the detection effect. The pick-up and placement rack 23 drives the clamping claw member 25 to move and dock with the boss portion 402, and the upper and lower clamping claw members 25 clamp the sample plate rack 4 at the rear end. After the movable seat 22 drives the pick-up and placement rack 23 to move, the sample plate rack 4 at the rear end is moved to the front end of the carrying frame 3, and then the sample plate rack 4 at the rear end pushes the remaining multiple sample plate racks 4, and moves backward by one unit, and the sample plate rack 4 at the rear end is rotated to the front end position, replacing the front end sample plate rack 4 to become the new front end sample plate rack 4.

[0030] Specifically, in this technical solution, the sample plate rack 4 is clamped by two clamping claws 25. Fig.13 , Fig.14 and Fig.15 As shown, the pick-and-place rack 23 is arranged in a "mouth"-shaped structure, and is divided into four parts: an upper frame body, a lower frame body, a left frame body, and a right frame body. Since the pick-and-place rack 23 is in a vertical state on the movable seat 22 after being arranged, the upper frame body and the lower frame body respectively movably penetrate the upper and lower sections of the movable seat 22, so that the pick-and-place rack 23 is positioned on the movable seat 22 in a movable state. Since the electric telescopic rod 24 is arranged in a parallel state with the pick-and-place rack 23 after being arranged, it is plugged in and fixedly installed on the left side wall of the movable seat 22 by bolts, and the output end thereof is plugged in and fixedly connected to the left side frame body of the pick-and-place rack 23 by bolts, the electric telescopic rod 24 is started to retract and operate, and the pick-and-place rack 23 is driven to extend and slide on the movable seat 22 by the electric telescopic rod 24. After the pick-and-place rack 23 slides, the right frame body thereof fits with the left side wall of the boss portion 402, driving the clamping claw member 25 to dock with the boss portion 402; Since the linkage frame 26 is arranged in a "U"-shaped structure, it is divided into a longitudinal frame body and two transverse frames located on the upper and lower sides of the longitudinal frame body. After the linkage frame 26 is installed, the movable card is set in the right frame body groove cavity of the pick-and-place frame 23. Since the telescopic electromagnet 27 is arranged between the two transverse frames in the linkage frame 26, the telescopic electromagnet 27 is fixedly installed in the right frame body groove cavity of the pick-and-place frame 23 by bolts after it is installed, and its output end is plugged and fixedly connected to the longitudinal frame body of the linkage frame 26 by bolts. After the clamping claw member 25 is docked with the boss portion 402, the telescopic electromagnet 27 is started to extend and operate, and the linkage frame 26 is driven by the telescopic electromagnet 27 to slide in the right frame body of the pick-and-place frame 23; Since the section of the clamping claw 25 close to the sample plate rack 4 is the right section of the claw body, wherein the right section of the claw body is in an "L"-shaped structure, i.e., an "L"-shaped claw body, and the section of the clamping claw 25 away from the sample plate rack 4 is the left section of the claw body, wherein the left section of the claw body is in a "U"-shaped structure, i.e., a "U"-shaped claw body, and since the upper and lower sides of the right side frame of the pick-and-place rack 23 are provided with clamping claws 25, the middle part of the clamping claw 25 is rotatably connected with an axle column, and the clamping claw 25 is movably clamped in the right side frame groove cavity of the pick-and-place rack 23 after being placed, wherein the two ends of the axle column are respectively inserted and fixedly connected to the groove cavity walls on both sides of the right side frame of the pick-and-place rack 23 by bolts, and wherein the "U"-shaped claw body is placed in the right side frame groove cavity of the pick-and-place rack 23, and wherein the "L"-shaped claw body extends outward from the right side frame groove cavity of the pick-and-place rack 23, so that the clamping claw 25 is positioned on the right side frame of the pick-and-place rack 23 in an active state; Since the "U"-shaped claw body in the clamping jaw member 25 is inclined on the "L"-shaped claw body, the upper and lower clamping jaw members 25 are arranged in opposite states, that is, the "U"-shaped claw bodies in the upper and lower clamping jaw members 25 are combined to form an "eight"-shaped structure, and through-shaped slide grooves are provided on the frame walls of the "U"-shaped claw body in the clamping jaw member 25. Since the linkage frame 26 is placed between the upper and lower clamping jaw members 25, a convex block of an integrated structure is provided on the horizontal frame body of the linkage frame 26, wherein the convex block is inserted and passed through the bolt. A pin is fixedly connected, and after the linkage frame 26 is installed, the protrusion of the horizontal frame body is movably clamped in the frame cavity of the "U"-shaped claw body of the clamping claw member 25, and the two ends of the pin on the protrusion are movably inserted into the two side slide grooves of the "U"-shaped claw body of the clamping claw member 25. After the linkage frame 26 is driven to slide to the left, the horizontal frame body of the linkage frame 26 slides on the "U"-shaped claw body of the clamping claw member 25 with the assistance of the pin, and the clamping claw member 25 is turned over and closed on the right frame body of the pick-and-place frame 23; Since the left side wall of the sample plate rack 4 is arranged toward the box door panel 2, the boss portion 402 is an integrated structure and is vertically arranged at the center of the left side wall of the sample plate rack 4. After the clamping jaw 25 is flipped and closed, the flipping directions of the upper and lower clamping jaws 25 are opposite, so that the "L"-shaped claw body in the clamping jaw 25 is connected to the boss portion 402 in a snap-fit ​​manner, and the boss portion 402 is clamped and fixed by the two clamping jaws 25 to complete the clamping of the sample plate rack 4.

[0031] Specifically, in this technical solution, the sample plate rack 4 at the rear end is rotated to the front end of the carrying frame 3, according to Fig.11 , Fig.12 , Fig.13 and Fig.17 As shown, the left side plate wall of the box door plate 2 (i.e., the side away from the UV aging test box body 1) is provided with an open opening connected to the plate cavity in the box door plate 2, and the right side shell cavity wall of the shell cavity in the external shell 201 is set in an open state. After the external shell 201 is placed, its right side shell cavity wall is clamped and fixedly connected to the open opening of the left side plate wall in the box door plate 2 by bolts, and the shell cavity is connected to the plate cavity in the box door plate 2. After the supporting frame 3 is placed, its frame cavity corresponds to the plate cavity in the box door plate 2. The electric telescopic rod 24 is started to extend and operate, and the electric telescopic rod 24 is used to drive the pick-up and placement rack 23 to shrink and slide on the movable seat 22, and the two clamping claws 25 clamp the sample plate rack 4 at the rear end, and the pick-up and placement rack 23 shrinks and slides to drive the sample plate rack 4 at the rear end to separate from the supporting frame 3; Since the left groove wall at the rear end of the guide groove 301 is provided with a disengagement groove portion 3013 for rotating the sample plate rack 4, the width dimension of the disengagement groove portion 3013 is adapted to the width dimension of the sample plate rack 4, so that the sample plate rack 4 can freely enter and exit the disengagement groove portion 3013, and since a blocking plate 30 for limiting the guide rod portion 401 is provided at the disengagement groove portion 3013, the blocking plate 30 is symmetrically arranged about the horizontal center axis of the bearing frame 3, and the upper and lower blocking plates 30 are respectively placed on the upper and lower guide grooves 301, and the upper end of the blocking plate 30 is rotatably connected with a shaft column, which is movably clamped in the disengagement groove portion 3013 after being placed, and the two ends of the shaft column are respectively inserted and fixedly connected to the groove walls on both sides of the disengagement groove portion 3013 by bolts, and then because the blocking plate 30 is connected to the groove wall of the disengagement groove portion 3013 A second torsion spring 31 for resetting is installed. The second torsion spring 31 is symmetrically arranged about the vertical center axis of the blocking plate 30. After being arranged, the second torsion spring 31 is movably sleeved on the center axis column of the blocking plate 30, one end of which is clamped on the blocking plate 30, and the other end of which is clamped on the groove cavity wall of the detachment groove 3013. The sample plate holder 4 at the rearmost end is detached from the carrier frame 3, so that the guide rod portion 401 is detached from the guide groove 301 at the detachment groove 3013. When the guide rod portion 401 is detached from the detachment groove 3013, the blocking plate 30 is pushed and turned over and unfolded in the detachment groove 3013, and the second torsion spring 31 is squeezed and elastically deformed. When the guide rod portion 401 is detached from the detachment groove 3013, the elastic deformation of the second torsion spring 31 is used for resetting, so that the blocking plate 30 is reset and turned over and closed in the detachment groove 3013. Since the front and rear ends of the rotating lead screw 20 are fixedly connected with bearings, the rotating lead screw 20 is placed in the middle of the shell cavity of the external shell 201 in a horizontal state. After placement, the front and rear ends are respectively connected with bearings and inserted into the front and rear shell cavity walls of the external shell 201. In addition, since the servo motor 21 is fixedly installed on the rear shell wall of the external shell 201 by bolts after placement, the output end is fixedly connected with the rear end of the rotating lead screw 20. When the servo motor 21 is started to operate, the rotating lead screw 20 is driven by the servo motor 21 to rotate in the middle of the shell cavity of the external shell 201. Since the movable seat 22 is a block-shaped structure, rollers are rotatably connected on its upper and lower sides at equal intervals. After the movable seat 22 is placed, its upper and lower ends are respectively connected with rollers and movably clamped on the upper and lower shell cavity walls of the external shell 201, so that the movable seat 22 is positioned in the external shell 201 in an active state. Since the middle part of the movable seat 22 is interlaced with the rotating screw 20 and threadedly connected together, the sample plate rack 4 at the rear end is driven to break away from the bearing frame 3 and move to the plate cavity of the box door plate 2. After the rotating screw 20 rotates, the threaded connection between the rotating screw 20 and the movable seat 22 allows the movable seat 22 to slide in the shell cavity of the external shell 201, and the movable seat 22 drives the pick-up and placement rack 23 to slide in the external shell 201, that is, the pick-up and placement rack 23 drives the sample plate rack 4 at the rear end to move forward in the plate cavity of the box door plate 2. Since a through slot 302 for rotating the sample plate rack 4 is provided at the front end of the supporting frame 3, and the through slot 302 is provided with a left opening facing the plate cavity in the box door plate 2, after the sample plate rack 4 moves forward, it corresponds to the left opening of the through slot 302, and the pick-up and placement rack 23 is driven to extend and slide again, so that the sample plate rack 4 at the rear end enters the frame cavity of the supporting frame 3 through the through slot 302, and the sample plate rack 4 drives the guide rod portion 401 to form a sliding structure in the guide slot 301, and the movable seat 22 drives the pick-up and placement rack 23 to slide backward, and the sample plate rack 4 at the rear end pushes the other multiple sample plate racks 4 and moves backward by one unit, so that the sample plate rack 4 at the rear end is rotated to the front end position of the frame cavity in the supporting frame 3, so that the sample plate rack 4 at the rear end replaces the sample plate rack 4 at the front end to become the new sample plate rack 4 at the front end.

[0032] At the same time, in this technical solution, according to Fig.11 , Fig.16 and Fig.17As shown, the front and rear sections of the guide rod portion 401 are both provided with a pin member 28. Since the pin member 28 is composed of a nail head portion and a nail tail portion, wherein the nail head portion is a hemispherical structure, after the pin member 28 is installed, the nail tail portion is movably clamped in the groove cavity of the guide rod portion 401, and its nail head portion movably penetrates through the groove cavity of the guide rod portion 401 and extends outward, so that the pin member 28 is positioned on the guide rod portion 401 in an active state. In addition, since a fourth spring 29 is installed at the sliding connection between the guide rod portion 401 and the pin member 28, the fourth spring 29 is movably inserted into the groove cavity of the guide rod portion 401 after installation, and the other end of the fourth spring 29 presses against the nail tail portion of the pin member 28, and the other end of the fourth spring presses against the groove cavity wall of the guide rod portion 401. The front section of the guide groove 301 is provided with a size that matches the hemispherical end of the pin member 28. When the frontmost sample plate rack 4 is pushed to slide to the next unit, the hemispherical end of the pin member 28 is set, and the pin member 28 is squeezed and slid on the guide rod portion 401, so that the fourth spring 29 is squeezed and elastically deformed. When the rearmost sample plate rack 4 rotates to the frontmost position, the elastic deformation of the fourth spring 29 is used to make the pin member 28 extend and slide on the guide rod portion 401, and the hemispherical end of the pin member 28 is connected to the positioning groove portion 3011 in a snap-fit ​​manner, so as to position the rearmost sample plate rack 4 after rotation, that is, to limit it to the remaining multiple sample plate racks 4, so as to prevent the sample plate rack 4 from being randomly displaced in the frame cavity of the carrier frame 3. Since the slide groove portion 3012 is opened in the rear section of the guide groove 301, its specifications and dimensions are compatible with the hemispherical end of the pin member 28. The hemispherical end of the pin member 28 is connected to the slide groove portion 3012 in a sliding manner. When the frontmost sample plate rack 4 is pushed to slide to the next unit, the hemispherical end of the pin member 28 moves into the slide groove portion 3012, which does not affect the sliding of the hemispherical end of the pin member 28, that is, it does not affect the rotation movement of the remaining multiple sample plate racks 4.
