Description

Technical Field

[0001] This invention relates to a screening machine, and more particularly to an optical fiber strength screening machine. Background Technology

[0002] Optical fibers are generally used for long-distance information transmission. After the optical fibers are manufactured, their toughness needs to be sampled and tested. Then, the unqualified fibers are screened out to ensure the quality of the optical fibers.

[0003] People typically place the optical fibers to be tested on a workbench, then place them one by one into the testing instrument for testing. After the testing is completed, the tested optical fibers are removed. Then, the user needs to classify and place the qualified and unqualified optical fibers according to the test results. Qualified and unqualified optical fibers may be mixed together, making it difficult for staff to distinguish them.

[0004] Therefore, it is necessary to design a fiber strength screening machine that can mark qualified optical fibers. Summary of the Invention

[0008] Furthermore, the extension mechanism includes a second support plate, a second movable rod, a second movable plate, and a third spring. The second support plate is located at the top center of the first support plate, and the second movable rods are slidably located on both sides of the second support plate. The second movable plates are located on the inner sides of the second movable rods, and the third spring connects the second movable plate and the second support plate.

[0009] Furthermore, it also includes a measuring mechanism, which includes a first rack, a loading plate, a second fixed plate, a first rotating shaft, a sponge ball, and a first gear. The bottom of the first movable plate is provided with a first rack connected to it on the side away from the third fixed rod. The loading plate is provided in the middle of the top of the first support plate. The second fixed plate is provided in the middle of the top of the first support plate. The first rotating shaft is rotatably provided on the second fixed plate. The sponge ball is provided on one side of the first rotating shaft and is located inside the loading plate. The first gear is provided on the side of the first rotating shaft away from the sponge ball.

[0010] Furthermore, it also includes a fixing mechanism, which includes a third fixed plate, a third movable plate, a pressure rod, a fourth spring, a fifth fixed rod, a fourth movable plate, and a fifth spring. The third fixed plate is provided on one side of the top of the first support plate, and the third movable plate is slidably provided on the third fixed plate. Two fourth springs are connected between the third movable plate and the third fixed plate. A pressure rod is connected to the side of the third movable plate near the first fixed plate. The fifth fixed rods are symmetrically provided on the first fixed plate near the motor side, and the fourth movable plates are slidably provided between the fifth fixed rods. A fifth spring is connected between the fourth movable plate and the fifth fixed rod.

[0011] Furthermore, it also includes a drive mechanism, which includes a second rack, a second bracket, a second rotating shaft, a second gear, and a first rotating plate.

[0014] The beneficial effects are: 1. The user fixes one side of the optical fiber between the second pressure plate and the first fixed plate, and then moves the right side of the optical fiber through the first movable plate, so that the optical fiber can be unfolded, making it convenient for the first pressure plate to test the optical fiber.

[0015] 2. The user loads pigment into the loading plate. When the first movable plate moves the first rack to the right, the first rack meshes with the first gear, causing the first rotating shaft and the sponge ball to rotate half a turn. Then, the side of the sponge ball with pigment faces upward. When the first pressure plate detects the optical fiber, it causes the optical fiber to move downward and contact the sponge ball. In this way, the optical fiber with better toughness will come into contact with the sponge ball, and the optical fiber will be covered with pigment. This allows for the identification of qualified and unqualified optical fibers. Attached Figure Description

Detailed Implementation

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] A fiber strength screening machine, such as Figure 1-7 As shown, it includes a base 1, a first support plate 2, a support frame 3, a first fixed rod 4, a second fixed rod 5, a first movable rod 6, a first pressure plate 7, a first spring 8, a moving mechanism 9, and an extension mechanism 10. The base 1 is provided with a first support plate 2 at its top. The support frame 3 is provided with a support frame 3 on its top right side. The support frame 3 is provided with a first fixed rod 4. The support frame 3 is provided with a second fixed rod 5 symmetrically arranged on its top right side. The first movable rod 6 is slidably arranged between the first fixed rod 4 and the second fixed rod 5. The second fixed rod 5 and the first movable rod 6 are both connected by a first spring 8. The first pressure plate 7 is provided with the bottom left side of the first movable rod 6. The first support plate 2 is provided with a moving mechanism 9 and an extension mechanism 10.

[0035] The moving mechanism 9 includes a first fixed plate 91, a third fixed rod 92, a lead screw 93, a first movable plate 94, a fourth fixed rod 95, a second pressure plate 96, a second spring 97, a first bracket 98, a motor 99, and a flat belt 910. The first fixed plate 91 is symmetrically arranged on the top of the first support plate 2. The third fixed rod 92 is arranged between the front sides of the two first fixed plates 91. The lead screw 93 is rotatably arranged between the rear sides of the two first fixed plates 91. The first movable plate 94 is threaded onto the lead screw 93. The first movable plate 94 is slidably connected to the third fixed rod 92. The fourth fixed rod 95 is arranged on both the front and rear sides of the top of the first movable plate 94. The second pressure plate 96 is slidably arranged between the two fourth fixed rods 95. The second spring 97 is connected between the second pressure plate 96 and the fourth fixed rod 95. The first bracket 98 is arranged on the top left side of the first support plate 2. The motor 99 is arranged on the first bracket 98. The output shaft of the motor 99 is connected to the left end of the lead screw 93 through a pulley and a flat belt 910.

[0036] The extension mechanism 10 includes a second support plate 101, a second movable rod 102, a second movable plate 103, and a third spring 104. The second support plate 101 is located at the top center of the first support plate 2. The second movable rod 102 is slidably located on both the left and right sides of the middle of the second support plate 101. The second movable plate 103 is located on the inner side of the second movable rod 102. The third spring 104 is connected between the second support plate 101 and the second movable plate 103.

[0037] When a user needs to test the strength of an optical fiber, this machine can be used. First, the optical fiber to be tested is passed through the first fixed plate 91. Then, the second pressure plate 96 is moved upward, compressing the second spring 97. The optical fiber is then placed on the first movable plate 94, and no force is applied to the second pressure plate 96. Under the reset action of the second spring 97, the second pressure plate 96 moves downward to fix the optical fiber. Then, the motor 99 is started. The output shaft of the motor 99 rotates, driving the lead screw 93 to rotate via the pulley and flat belt 910. Under the guidance of the third fixed rod 92, the first movable plate 94 moves to the right along the lead screw 93 to extend the optical fiber, so that both sides of the optical fiber are located on the first movable plate 94 and the first fixed plate 91, respectively. Then, the first movable rod 6 and the first pressure plate 7 are moved downward. The movement causes the first pressure plate 7 to press down on the middle position of the optical fiber, compressing the first spring 8, thereby allowing the fiber's toughness and strength to be tested. The first pressure plate 7 presses the optical fiber downward, and it comes into contact with the second movable plate 103, causing the second movable plate 103 to move to both sides, compressing the third spring 104. When the user no longer applies force to the first movable rod 6 and the first pressure plate 7, under the reset action of the first spring 8, the first pressure plate 7 and the first movable rod 6 move upward to reset. Under the reset action of the third spring 104, the second movable plate 103 and the second movable rod 102 move inward to reset. After the test is completed, the optical fiber is removed, and the user restarts the motor 99, causing the output shaft of the motor 99 to drive the lead screw 93 to rotate in the opposite direction, thereby causing the first movable plate 94 to move to the left to reset.

[0038] Example 2

[0039] Based on Example 1, such as Figure 1 , Figure 3 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, it also includes a measuring mechanism 11, which includes a first rack 111, a loading plate 112, a second fixed plate 113, a first rotating shaft 114, a sponge ball 115, and a first gear 116. The first movable plate 94 has a first rack 111 connected to its bottom rear side. The loading plate 112 is located in the middle of the top of the first support plate 2. The second fixed plate 113 is located in the middle of the top of the first support plate 2. The second fixed plate 113 is located behind the loading plate 112. The first rotating shaft 114 is rotatably mounted on the second fixed plate 113. The sponge ball 115 is located in front of the first rotating shaft 114 and is located inside the loading plate 112. The first gear 116 is located behind the first rotating shaft 114. The first rack 111 and the first gear 116 cooperate with each other.

[0040] The user fills the loading plate 112 with pigment. The side of the sponge ball 115 that contacts the loading plate 112 will be covered with pigment. When the first movable plate 94 drives the first rack 111 to move to the right, the first rack 111 meshes with the first gear 116, causing the first rotating shaft 114 and the sponge ball 115 to rotate half a turn. Then, the side of the sponge ball 115 covered with pigment faces upward. When the first pressure plate 7 detects the optical fiber, it causes the optical fiber to move downward to contact the sponge ball 115. If the optical fiber contacts the sponge ball 115 and is covered with pigment, it indicates that the optical fiber has good toughness. If the optical fiber cannot contact the sponge ball 115, it indicates that the optical fiber has poor toughness. When the first movable plate 94 drives the first rack 111 to move to the left, the first rack 111 meshes with the first gear 116, causing the first rotating shaft 114 and the sponge ball 115 to rotate half a turn again.

[0041] It also includes a fixing mechanism 12, which includes a third fixing plate 121, a third movable plate 122, a pressure rod 123, a fourth spring 124, a fifth fixing rod 125, a fourth movable plate 126, and a fifth spring 127. The third fixing plate 121 is provided on the front side of the top of the first support plate 2. The third movable plate 122 is slidably provided on the third fixing plate 121. Two fourth springs 124 are connected between the third movable plate 122 and the third fixing plate 121. The pressure rod 123 is connected to the left side of the third movable plate 122. The fifth fixing rods 125 are symmetrically provided on the left side of the first fixing plate 91. The fourth movable plate 126 is slidably provided between the fifth fixing rods 125. The pressure rod 123 is located above the fourth movable plate 126. The fifth spring 127 is connected between the fourth movable plate 126 and the fifth fixing rod 125.

[0042] It also includes a drive mechanism 13, which includes a second rack 131, a second bracket 132, a second rotating shaft 133, a second gear 134, and a first rotating plate 135. The second rack 131 is provided on the front side of the first movable plate 94, and the second bracket 132 is provided on the top right front side of the first support plate 2. The second rotating shaft 133 is rotatably provided on the second bracket 132. The second gear 134 and the first rotating plate 135 are provided on the second rotating shaft 133. The first rotating plate 135 is located in front of the second gear 134, and the second rack 131 cooperates with the second gear 134.

[0043] When the first movable plate 94 drives the second rack 131 to move to the right, and the second rack 131 meshes with the second gear 134, the first movable plate 94 moves to the far right and fully unfolds the optical fiber. The rotation of the second gear 134 drives the second rotating shaft 133 and the first rotating plate 135 to rotate, pressing down on the third movable plate 122 through the first rotating plate 135. This causes the pressure rod 123 to press down on the fourth movable plate 126, compressing the fourth spring 124 and the fifth spring 127. At this time, the fourth movable plate 126 can... The optical fiber is clamped and fixed on the left side. After the optical fiber is tested, the first movable plate 94 drives the second rack 131 to move to the left. The second rack 131 drives the second gear 134 to rotate in the opposite direction, so that the second rotating shaft 133 and the first rotating plate 135 rotate in the opposite direction. The first rotating plate 135 no longer presses down on the third movable plate 122 and the pressure rod 123. Under the reset action of the fourth spring 124 and the fifth spring 127, the third movable plate 122 and the pressure rod 123 move upward to reset, and the fourth movable plate 126 moves upward to reset.

[0044] It also includes a pressing mechanism 14, which includes a fifth movable plate 141, a third bracket 142, a second rotating plate 143, a torsion spring 144, and a sixth fixed rod 145. The fifth movable plate 141 is connected to the rear side of the first movable plate 94. The third bracket 142 is provided on the rear side of the top of the first fixed plate 91 on the right side. The second rotating plate 143 is rotatably provided on the third bracket 142. The lower part of the fifth movable plate 141 and the second rotating plate 143 cooperate. The torsion spring 144 is connected between the second rotating plate 143 and the third bracket 142. The sixth fixed rod 145 is provided on the rear side of the first movable rod 6. The upper part of the second rotating plate 143 cooperates with the sixth fixed rod 145.

[0045] The first movable plate 94 drives the fifth movable plate 141 to move to the right. After the fifth movable plate 141 contacts the lower part of the second rotating plate 143, it squeezes the second rotating plate 143, causing the second rotating plate 143 to rotate. The torsion spring 144 deforms, and the second rotating plate 143 rotates to squeeze the sixth fixed rod 145, thereby driving the first movable rod 6 and the first pressure plate 7 to move downward. In this way, there is no need to manually press down the first pressure plate 7. When the first movable plate 94 drives the fifth movable plate 141 to move to the left, the fifth movable plate 141 disengages from the second rotating plate 143. The torsion spring 144 drives the second rotating plate 143 to rotate in the opposite direction and reset. Then the second rotating plate 143 no longer presses the sixth fixed rod 145.

[0046] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
