Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in combination with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] As Figure 1 shown, in combination with Figure 2A testing device for optical passive components of the present invention comprises a platform 1, a blanking component 2, a positioning component 3, a testing component 4, a stripping component 5 and a bearing seat 6.

[0028] The platform 1 is provided with a support seat 6 for transporting a test piece 11. The test piece 11 is an optical passive device that needs to be tested, and one side of the test piece 11 has a joint, which can be softly connected with the detection head 12 to realize the detection of the optical passive device; the support seat 6 is a flat plate for placing the device, and has side plates on both sides, and the two side plates block the two sides of the test piece 11. A spring is provided between the bottom of the support seat 6 and the turntable 13, so that the support seat 6 rises and resets.

[0029] The blanking assembly 2 is arranged on the platform 1 and blanks the stored test pieces 11 into the bearing seat 6 one at a time. The blanking assembly 2 is located at a blanking station of the platform 1 .

[0030] The positioning assembly 3 is disposed on the platform 1 and drives the test piece 11 to move to a position in the bearing seat 6. The location of the positioning assembly 3 is a positioning station of the platform 1.

[0031] The testing component 4 is arranged on the platform 1 and detects the test pieces 11 and marks the unqualified test pieces 11. The location of the testing component 4 is the testing station of the platform 1.

[0032] The material-removing assembly 5 is disposed on the platform 1 and guides the workpiece 11 to be tested to separate from the support seat 6 and exit the platform 1. The position where the material-removing assembly 5 is located is the material-removing station of the platform 1.

[0033] The support base 6 transports the test piece 11 through the blanking component 2, the positioning component 3, the test component 4 and the return component 5 in sequence. The support base 6 reciprocates the test piece 11 for testing, thereby realizing the full process automation of blanking, positioning, testing and return of optical passive components. The detection process has accurate positioning and precise detection, avoiding the current situation where manual detection is required and prone to misdetection.

[0034] exist Figure 3 In a preferred embodiment shown, in order to realize automated detection, the support seat 6 moves vertically relative to the platform 1 , and a paddle 61 is provided on the lower surface of the support seat 6 ; the test assembly 4 includes a pressing block 41 and a movable portion 42 .

[0035] The pressing block 41 is arranged just above the bearing seat 6 and moves vertically relative to the platform 1. The pressing block 41 presses down to hold the test piece 11 and pushes the bearing seat 6 down, or the pressing block 41 rises and resets. A gantry is arranged on the platform 1, and the gantry is erected just above the detection station. A lifting drive mechanism, such as a telescopic gas rod or an electric cylinder, is arranged on the gantry. The lifting drive mechanism is connected to the pressing block 41 to drive the pressing block 41 to move up and down.

[0036] The movable portion 42 moves horizontally relative to the bearing seat 6; the movable portion 42 is L-shaped, and one end of the bottom of the movable portion 42 extends to the bottom of the bearing seat 6 and is provided with a wedge groove 401. The paddle 61 is an inclined bar or an S-shaped bar. When the paddle 61 moves down with the bearing seat 6 and is inserted into the wedge groove 401, the paddle 61 cooperates with the wedge groove 401, and the movable portion 42 moves along the inclined portion of the paddle 61, so that the movable portion 42 can be pulled close to the bearing seat 6, or the paddle 61 exits the wedge groove 401, and the movable portion 42 moves away from the bearing seat 6 and moves to reset, which can be on the platform 1 A support is arranged on the top, a guide rod is passed through the support, a spring is sleeved on the guide rod, and the movable part 42 is connected to the guide rod so that the spring can realize reset movement; the top end of the movable part 42 extends vertically to the side of the bearing seat 6, and a row of plug strips can be arranged at the top end of the movable part 42, and a spring is arranged between the row of plug strips and the top end of the movable part 42 of the detection head 12, and a plurality of detection heads 12 are arranged horizontally on the row of plug strips, and each detection head 12 corresponds to each joint on the test piece 11, moves horizontally with the movable part 42 and is softly connected to the test piece 11 for detection, or the detection head 12 is out of contact with the test piece 11. When the pressure block 41 descends and presses against the test piece 11 and the bearing seat 6 first descends to a certain height, the paddle 61 is inserted into the wedge groove 401 and the movable part 42 is close to the test piece 11, so that the detection head 12 is softly plugged with the joint on the test piece 11, and the tail of each detection head 12 is connected to the detector so that the test piece 11 can be tested whether it is qualified or not. If the test is qualified, the pressing block 41 will rise, and the bearing seat 6 will also rise and reset and transfer to the next station. If the test is unqualified, the pressing block 41 will continue to press down and mark the surface of the test piece 11. Since there is a spring between the bearing seat 6 and the turntable 13, and there is also a spring between the row of plugs and the movable part 42, the spring between the row of plugs and the movable part 42 plays a buffering role. When the bearing seat 6 continues to descend due to failure, the row of plugs will also descend relative to the movable part 42, thereby avoiding a large height difference between the detection head 12 on the row of plugs and the joint on the test piece 11, which causes the detection head 12 to pull the test piece 11 and cause damage. And since the detection head 12 and the joint are soft plug-in, it can also avoid damage as much as possible.

[0037] exist Figure 6 In a preferred embodiment shown, in order to mark the unqualified test piece 11 , the test assembly 4 further includes a marking head 43 .

[0038] Among them, a groove 402 is formed on the lower surface of the briquette 41, and the marking head 43 is arranged in the groove 402. A spring is arranged between the marking head 43 and the top surface of the groove 402. A convex block with the word "FAIL" is arranged on the lower surface of the marking head 43. In the initial state, there is a height difference between the lower surface of the marking head 43 and the lower surface of the briquette 41. When it is detected that the test piece 11 is unqualified and the briquette 41 continues to descend, the marking head 43 moves vertically relative to the briquette 41 at the same time. When the marking head 43 descends, the lower surface of the marking head 43 is flush with the lower surface of the briquette 41, so that the lower surface of the marking head 43 contacts the test piece 11 and makes a mark on the surface of the test piece 11, or the marking head 43 rises and resets simultaneously with the briquette 41. The principle of making the mark can be formed by forcibly squeezing the surface of the test piece 11 through the convex block, or a heating mechanism can be arranged inside the marking head 43, and the marking head 43 and the convex block are heated to thermally print a mark on the surface of the test piece 11. Other ways that can achieve the marking function can also be adopted.

[0039] In Figure 5 In a preferred embodiment shown, when the test piece 11 falls from the blanking assembly 2 onto the bearing seat 6, there will be a certain difference in the blanking positions of each test piece 11, which will affect the subsequent detection and may cause the connectors on some test pieces 11 to be unable to be properly soft-connected to the detection head 12. Therefore, the positioning assembly 3 in this embodiment includes a pressing plate 31 and a slider 32.

[0040] Among them, the pressing plate 31 is arranged directly above the bearing seat 6 and moves vertically relative to the bearing seat 6. The pressing plate 31 descends and contacts the test piece 11, and the pressing plate 31 restricts the test piece 11 from detaching from the bearing seat 6, or the pressing plate 31 moves away from the bearing seat 6. A gantry and a telescopic mechanism can be arranged at the positioning station of the platform 1 to drive the pressing plate 31 to move up and down; or other methods can also be adopted, which will be described in detail in subsequent embodiments.

[0041] The slider 32 is arranged on the side surface of the bearing seat 6 and moves horizontally relative to the bearing seat 6. Similarly to the movable part 42, the slider 32 also realizes horizontal reciprocating movement through a support, a guide rod and a spring. The slider 32 moves towards the test piece 11 while descending with the pressing plate 31. The slider 32 abuts against and pushes the test piece 11 to move into place in the bearing seat 6, or the slider 32 moves away from the test piece 11 while rising with the pressing plate 31. By pressing and pushing the test piece with the pressing plate 31 and pushing the test piece 11 to move horizontally with the slider 32, after each test piece 11 passes through the positioning station, the horizontal relative position and the vertical relative position of the test piece 11 and the bearing seat 6 are kept consistent.

[0042] In Figure 5In a preferred embodiment shown, in order to accurately position the workpiece 11 to be measured, flanges 111 are provided on both sides of the side surface of the workpiece 11 to be measured, and connectors are provided on the side surface where the flanges 111 are provided; when the workpiece 11 to be measured is dropped onto the carrier 6, the flanges 111 are away from the carrier 6, and the slider 32 pushes the workpiece 11 to be measured to move horizontally relative to the carrier 6, so that the flanges 111 abut against the side plate of the carrier 6 and the workpiece 11 to be measured moves into place within the carrier 6, which can ensure that the horizontal relative position of each workpiece 11 to be measured and the carrier 6 remains consistent.

[0043] In Figure 5 In a preferred embodiment shown, in order to link the pressure plate 31 and the slider 32 to avoid the need for separate drive mechanisms for the pressure plate 31 and the slider 32 to perform actions, a baffle 7, a first connecting rod 8 and an inclined rod 9 are further included.

[0044] Among them, the baffle 7 is arranged on the other side surface of the carrier 6 and on the opposite side of the slider 32.

[0045] Both ends of the first connecting rod 8 are respectively connected to the baffle 7 and the slider 32.

[0046] The inclined rod 9 is arranged above the platform 1 and moves synchronously with the pressure plate 31; the inclined rod 9 is inclined relative to the surface of the platform 1. When the inclined rod 9 descends and abuts against the baffle 7, the inclined rod 9 guides the baffle 7 away from the carrier 6 and drives the slider 32 to approach the carrier 6 through the first connecting rod 8. The principle of the inclined rod 9 guiding the movement of the baffle 7 is the same as that of the dial 61. When the pressure plate 31 descends to press the workpiece 11 to be measured, the inclined rod 9 will gradually push the baffle 7 to move backward as it descends. When the baffle 7 moves backward, it will pull the slider 32 to move forward through the first connecting rod 8, and the slider 32 will push the workpiece 11 to be measured to move horizontally, thus realizing the linked action of the pressure plate 31 and the slider 32.

[0047] In Figure 5 In a preferred embodiment shown, a turntable 13 is further included.

[0048] Among them, the turntable 13 is arranged on the platform 1 and rotates horizontally relative to the platform 1.

[0049] Four carriers 6 are evenly arranged on the edge of the turntable 13; the blanking assembly 2, the positioning assembly 3, the testing assembly 4 and the unloading assembly 5 are evenly arranged at the 0°, 90°, 180° and 270° positions of the turntable 13 and are arranged in one-to-one correspondence with the four carriers 6.

[0050] The drive assembly 14 is arranged below the platform 1 and is used to drive the turntable 13 to rotate, so as to realize the cyclic switching of four workstations on the platform 1 through the rotation of the four carriers 6.

[0051] In Figure 5In a preferred embodiment shown, the unloading assembly 5 includes a push plate 51, and the push plate 51 is arranged on the side of the bearing seat 6 facing the center of the turntable 13; a slideway is also arranged at the unloading station, and the slideway is arranged on the side of the bearing seat 8. The push plate 51 moves horizontally and pushes the test piece 11 out of the bearing seat 6, and the test piece 11 is unloaded from the platform 1 through the slideway.

[0052] In order to enable the pressure block 41, the pressure plate 31, the slider 32 and the push plate 51 to be linked, so that the positioning assembly 3, the detection assembly 4 and the unloading assembly 5 can perform linked actions through the same set of driving mechanisms, the testing device further includes a second connecting rod 15 and a third connecting rod 16.

[0053] Wherein, both ends of the second connecting rod 15 are respectively connected to the pressure plate 31 and the pressure block 41, and one end of the inclined rod 9 far from the platform 1 is connected to the second connecting rod 15.

[0054] Both ends of the third connecting rod 16 are respectively connected to the baffle 7 and the push plate 51. Therefore, when the telescopic mechanism of the pressure block 41 drives it to descend, the pressure plate 31 will also descend accordingly through the second connecting rod 15; at the same time, the inclined rod 9 also descends with the pressure block 41 through the second connecting rod 15. When the inclined rod 9 descends, it will drive the baffle 7 to move horizontally. The baffle 7 drives the slider 32 and the push plate 51 to translate in the same direction through the first connecting rod 8 and the third connecting rod 16 respectively. When the slider 32 pushes the test piece 11 at the corresponding position to move into place in the bearing seat 6, the push plate 51 pushes the test piece 11 at the corresponding position out of the bearing seat 6 and exits the platform 1. In order to realize the reset of the push plate 51, a spring can be arranged between the middle part of the third connecting rod 16 and the support member arranged in the middle of the platform 1.

[0055] In Figure 4 In a preferred embodiment shown, the blanking assembly 2 includes a storage barrel 21, a tongue pressing plate 22 and a sliding rod 23.

[0056] Wherein, the storage barrel 21 is arranged directly above the bearing seat 6 at the corresponding position. The upper and lower ends of the storage barrel 21 are through. A number of test pieces 11 are loaded vertically in the storage barrel 21. Friction blocks are arranged on the inner wall of the storage barrel 21. The friction blocks are in frictional contact with the test pieces 11 and limit the test pieces 11 from detaching from the storage barrel 21.

[0057] The tongue pressing plate 22 is arranged in the storage barrel 21 and presses on the uppermost test piece 11.

[0058] One end of the sliding rod 23 is connected to the tongue pressing plate 22 and the other end vertically extends below the platform 1 and is connected to the driving assembly 14; the sliding rod 23 intermittently moves downward under the drive of the driving assembly 14. The sliding rod 23 pulls the tongue pressing plate 22 to move synchronously. The tongue pressing plate 22 presses against the test piece 11 and cancels the frictional force between the test piece 11 and the friction block, so that a number of test pieces 11 are detached from the storage barrel 21 one by one.

[0059] In Figure 4 In a preferred embodiment shown in Figure 4 , the driving assembly 14 includes a motor 141, a rotating shaft 142, a main gear 143, a second driven gear 145, a rack 146 and a linkage gear set 147.

[0060] Among them, the motor 141 is arranged on the lower surface of the platform 1.

[0061] One end of the rotating shaft 142 passes through the center of the turntable 13 and drives the turntable 13 to rotate, and the other end extends below the platform 1.

[0062] The main gear 143 is arranged on the motor 141. The main gear 143 is provided with fan-shaped teeth, and the fan shape is one-fourth of a perfect circle.

[0063] The first driven gear 144 is sleeved on the end of the rotating shaft 142 extending below the platform 1 and rotates synchronously with the rotating shaft 142.

[0064] The second driven gear 145 is arranged below the platform 1. The second driven gear 145 and the first driven gear 144 are respectively located on opposite sides of the main gear 143.

[0065] The rack 146 is arranged on the end of the sliding rod 23 extending below the platform 1.

[0066] The linkage gear set 147 is cooperatively connected between the second driven gear 145 and the rack 146; the linkage gear set 147 includes a first transmission wheel cooperating with the second driven gear 145, a second transmission wheel coaxially arranged with the first transmission wheel, a first bevel gear cooperating with the second transmission wheel, and a second bevel gear cooperating with both the first bevel gear and the rack 146. This linkage gear set 147 is a common linkage mechanism, so it is regarded as an integral structure.

[0067] The main gear 143 rotates under the drive of the motor 141 and alternately cooperates with the first driven gear 144 and the second driven gear 145; the second driven gear 145 drives the sliding rod 23 to move downward intermittently through the linkage gear set 147. When the main gear 143 first cooperates with the first driven gear 144 and rotates one-fourth of a circle, it will drive the turntable 13 to also rotate one-fourth of a circle, thereby driving each carrier 6 to move from the current station to the next station; when the main gear 143 rotates another one-fourth of a circle, it is not linked with any gear; when the main gear 143 rotates another one-fourth of a circle, it will cooperate with the second driven gear 145, so that the blanking assembly 2 blanks a test piece 11, and when the main gear 143 rotates another one-fourth of a circle, it just rotates a full circle, and at this time it is not linked with any gear, until the main gear 143 starts to rotate the next circle and will cooperate with the first driven gear 144 again. The above design can enable the main gear 143 to move the carrying part 6 to the next station and at the same time blank the next test piece 11 during each full rotation.

[0068] Working principle:

[0069] In the initial state, the carrier 6 at the blanking station is empty, while the carriers 6 at the other three stations are provided with the workpieces 11 to be tested.

[0070] First, the motor 141 drives the main gear 143 to cooperate with the second driven gear 145 to rotate a first quarter turn, and the blanking assembly 2 blanks a workpiece 11 to be tested onto the carrier 6 at the blanking station. At this time, there are workpieces 11 to be tested at all four stations.
