DETAILED DESCRIPTION

[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] Reference Figure 1-11 , a bending degree testing device for processing flexible shielding materials for radiation protection, comprising a base 1, a test bench 9 is installed on the top of the base 1, a guide groove 2 is provided between the base 1 and the test bench 9, a driving mechanism 3 is installed inside the guide groove 2, a first guide groove 5 distributed vertically and a second guide groove 8 distributed horizontally are provided on the surface of the test bench 9, and the first guide groove 5 and the second guide groove 8 are arranged vertically, a first limiting rail 11 coaxially distributed with the first guide groove 5 is installed inside the test bench 9, a second limiting rail 10 parallel to the second guide groove 8 is installed inside the test bench 9, a bending mechanism 6 is slidably installed inside the first guide groove 5, positioning mechanisms 7 are slidably installed inside both ends of the second guide groove 8, and linkage arms 16 are provided between the two sides of the bending mechanism 6 and the positioning mechanism 7, the bottom of the positioning mechanism 7 is slidably matched with the second limiting rail 10, a transmission arm mechanism 4 is slidably installed inside the first limiting rail 11, and the transmission arm mechanism 4 is arranged between the driving mechanism 3 and the bending mechanism 6.

[0031] In the present invention, a synchronously moving bending mechanism 6 and a positioning mechanism 7 are provided. When the bending degree of the flexible shielding material is tested, the distance between the two end positions of the flexible shielding material strip and the bending point is always kept consistent, avoiding the pushing and stretching phenomenon on the middle part of the flexible shielding material strip, thereby ensuring that the curvature of the flexible screen is consistent each time it is bent. During the test, the bending mechanism 6 is first adjusted to the innermost end. At this time, the transmission arm mechanism 4 is in a straight line state. By adjusting the distance between the driving mechanism 3 and the bending mechanism 6, and the transmission point position between the driving mechanism 3 and the transmission arm mechanism 4, the movement distance between the bending mechanism 6 and the positioning mechanism 7 is adjusted, thereby setting the flexible shielding material strip. The bending angle during the test, after which the bending mechanism 6 and the two positioning mechanisms 7 are moved to the same straight line, multiple groups of cut flexible shielding material strips are inserted into the bending mechanism 6, and the two ends of the flexible shielding material strips are respectively fixed in the two positioning mechanisms 7. The positions on both sides of the flexible shielding material strips are consistent with the spacing on both sides of the bending mechanism 6, completing the installation operation of multiple groups of flexible shielding material strips. Finally, the bending mechanism 6 is driven to move back and forth by the driving mechanism 3 and the transmission arm mechanism 4, and the two positioning mechanisms 7 are driven to move synchronously by the linkage arm 16 to perform a fixed-angle bending operation on the flexible shielding material strips to obtain accurate flexible shielding material bending test data.

[0032] As a further solution in the present invention, the bending mechanism 6 includes a bending seat 61 slidably installed with the first guide groove 5, and a bending die seat 62 is plugged and installed on the top of the bending seat 61. Two parallel bending tubes 63 are fixedly installed on the top of the bending die seat 62, and a plurality of blocking blocks 64 are sleeved between the two bending tubes 63. In the present invention, the middle section of the flexible shielding material strip is inserted between the two bending tubes 63. As the bending mechanism 6 moves forward and backward, the bending tube 63 is used to effectively bend the surface of the flexible shielding material strip, and the two ends of the flexible shielding material strip are fixed by the positioning mechanism 7, and the distance between the bending mechanism 6 and the positioning mechanism 7 remains fixed when the bending mechanism 6 moves, thereby reducing the moving friction between the surface of the flexible shielding material strip and the surface of the bending tube 63, thereby improving the accuracy of the bending degree test of the flexible shielding material.

[0033] As a further solution in the present invention, a cooling assembly 65 is installed between the tops of the two bending tubes 63, and the cooling assembly 65 includes an air cavity shell 651 plugged into the top of the bending tube 63, and a cooling fan 652 installed on the side of the air cavity shell 651. The cooling assembly 65 also includes an arc groove 653 arranged on the surface of the bending tube 63. In the present invention, when the bending mechanism 6 bends the flexible shielding material strips, and the bending tube 63 bends multiple groups of flexible shielding material strips, as the surface of the flexible shielding material strips bends, heat is generated, and cold air is introduced into the inside of the bending tube 63 through the cooling fan 652, thereby maintaining the surface temperature of the bending tube 63 constant, and reducing the surface temperature of the flexible shielding material strips, avoiding interference between multiple groups of flexible shielding material strips, and further improving the accuracy of the bending degree test of the flexible shielding material.

[0034] As a further solution in the present invention, the positioning mechanism 7 includes a positioning seat 71 that slides with the second guide groove 8 and the second limiting rail 10. A positioning rod 72 is rotatably installed on the top of the positioning seat 71, and a clamping groove 74 is provided in the middle of the positioning rod 72. The outer surface of the positioning rod 72 is screwed with multiple equally distributed blocking rings 73, and the outer side of the clamping groove 74 is clamped with a locking piece 75. In the present invention, when the flexible shielding material strip is installed, the two ends of the flexible shielding material strip are inserted into the clamping groove 74, and the two ends of the flexible shielding material strip are fixed by the locking piece 75. The two positioning mechanisms 7 move synchronously with the bending mechanism 6, and the positioning rod 72 is rotatably installed on the positioning seat 71. The positioning rod 72 rotates following the change of the bending angle of the middle part of the flexible shielding material strip, keeping the distance between the end of the flexible shielding material strip and the bending point consistent, thereby avoiding stress on the flexible shielding material strip that affects the bending degree test.

[0035] As a further solution in the present invention, the locking member 75 includes an elastic clip 751 with a U-shaped structure, and the front end position of the elastic clip 751 is provided with a toothed portion 753 that cooperates with the edge of the clamping groove 74, and the side of the elastic clip 751 is provided with an L-shaped locking portion 752. In the present invention, the end of the flexible shielding material strip is embedded in the elastic clip 751, and the surface of the flexible shielding material strip is squeezed outward by the locking portion 752, thereby effectively clamping and fixing the end of the flexible shielding material strip. When the front end of the elastic clip 751 is embedded in the clamping groove 74, the end of the flexible shielding material strip is locked and fixed to prevent the flexible shielding material strip from loosening during the bending test.

[0036] As a further solution in the present invention, the transmission arm mechanism 4 includes a transmission arm main rod 41 that slides with the first limiting track 11, and a transmission arm sub-rod 44 hinged between the transmission arm main rod 41 and the driving mechanism 3. The other end of the transmission arm main rod 41 is provided with a threaded pull rod 42 fixedly connected to the bending mechanism 6. In the present invention, the transmission arm main rod 41 relies on the cooperation between the transmission arm sub-rod 44 and the driving mechanism 3 to move back and forth in a straight line inside the first limiting track 11, thereby driving the bending mechanism 6 to move back and forth to perform a bending operation on the middle part of the flexible shielding material strip.

[0037] As a further solution in the present invention, the transmission arm mechanism 4 also includes a positioning slide 43 installed on the test bench 9. The front end of the transmission arm main rod 41 is provided with a through hole that slides with the positioning slide 43. The positioning slide 43 is distributed below the first guide groove 5. In the present invention, through the setting of the positioning slide 43, the motion trajectory of the transmission arm main rod 41 below the first guide groove 5 is limited, thereby improving the stability of the transmission process of the transmission arm mechanism 4.

[0038] As a further solution in the present invention, the driving mechanism 3 includes a driving base 32 slidably installed inside the guide groove 2, and a push rod motor 31 that drives the driving base 32 to move back and forth. A driving motor 33 is installed in the middle of the driving base 32, and a driving wheel 34 is installed on the top of the output shaft of the driving motor 33. A rectangular groove 35 is provided on the top of the driving wheel 34, and a distance adjustment component 36 rotatably connected to the transmission arm mechanism 4 is installed inside the rectangular groove 35. In the present invention, when the transmission arm mechanism 4 is in a straight line, the distance adjustment component 36 and the first guide groove 5 are located on the same straight line. The transmission distance between the driving mechanism 3 and the transmission arm mechanism 4 is adjusted by the distance adjustment component 36, and the position of the driving mechanism 3 is controlled by the push rod motor 31, thereby adjusting the spacing of the reciprocating motion of the bending mechanism 6 to control the bending angle of the flexible shielding material strip.

[0039] As a further solution of the present invention, the pitch adjustment assembly 36 includes a pitch adjustment rod 364 rotatably mounted inside the rectangular slot 35, and a servo motor 363 that drives the pitch adjustment rod 364 to rotate. A pitch adjustment block 361 rotatably connected to the transmission arm mechanism 4 is slidably mounted on the outer side of the pitch adjustment rod 364. A fan-shaped groove 365 is provided on the outer side of the pitch adjustment rod 364, and fan-shaped teeth 366 distributed at equal distances are provided on the side of the fan-shaped groove 365. The middle part of the pitch adjustment block 361 is provided with a fan-shaped groove 365. The locking tooth 362 meshes with the sector tooth 366. In the present invention, when the pitch adjustment rod 364 rotates 90° counterclockwise, the locking tooth 362 is located in the sector groove 365, and the pitch adjustment block 361 can be slid and adjusted inside the rectangular groove 35. After the spacing adjustment is completed, the pitch adjustment rod 364 rotates 90° clockwise, and the locking tooth 362 is embedded in the sector tooth 366, so that the position of the sector tooth 366 is fixed, and then the spacing of the reciprocating motion of the transmission arm mechanism 4 is adjusted. The adjustment process is simple and convenient.

[0040] As a further solution in the present invention, a movable cover 12 is provided at one end of the test bench 9, a test box 13 is installed above the other end of the test bench 9, and a rotating motor 14 is fixedly installed on the top of the test box 13. A protective cover 15 is provided at the front end of the output shaft of the rotating motor 14. In the present invention, when the bending degree of the flexible shielding material is tested, the bending mechanism 6, the positioning mechanism 7 and the flexible shielding material strip fixed thereto are all protected inside the protective cover 15 and the test box 13, thereby reducing the impact of the environment on the bending test of the flexible shielding material strip.

[0041] During the test, the bending mechanism 6 is first adjusted to the innermost end. At this time, the transmission arm mechanism 4 is in a straight line state. By adjusting the distance between the driving mechanism 3 and the bending mechanism 6, and the position of the transmission point between the driving mechanism 3 and the transmission arm mechanism 4, the movement distance between the bending mechanism 6 and the positioning mechanism 7 is adjusted, and then the bending angle of the flexible shielding material strip during the test is set. After that, the bending mechanism 6 and the two positioning mechanisms 7 are moved to the same straight line, and multiple groups of cut flexible shielding material strips are inserted into the bending mechanism 6, and the two ends of the flexible shielding material strips are respectively fixed in the two positioning mechanisms 7. The positions on both sides of the flexible shielding material strips are consistent with the distance on both sides of the bending mechanism 6, and the installation operation of multiple groups of flexible shielding material strips is completed. Finally, the bending mechanism 6 is driven to move back and forth by the driving mechanism 3 and the transmission arm mechanism 4, and the two positioning mechanisms 7 are driven to move synchronously by the linkage arm 16 to perform a fixed-angle bending operation on the flexible shielding material strip to obtain accurate flexible shielding material bending test data.
