DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0027] As Figure 1 shown, in combination with Figure 2The application discloses a testing device for an optical passive device, which comprises a platform 1, a material feeding assembly 2, a positioning assembly 3, a testing assembly 4, a material returning assembly 5 and a bearing seat 6.

[0028] The bearing seat 6 is arranged on the platform 1 and used for transporting the to-be-tested device 11.

[0029] The material feeding assembly 2 is arranged on the platform 1 and used for feeding the to-be-tested device 11 into the bearing seat 6 one by one.

[0030] The positioning assembly 3 is arranged on the platform 1 and used for driving the to-be-tested device 11 to move to a position in the bearing seat 6.

[0031] The testing assembly 4 is arranged on the platform 1 and used for testing the to-be-tested device 11 and marking the unqualified to-be-tested device 11.

[0032] The material returning assembly 5 is arranged on the platform 1 and used for guiding the to-be-tested device 11 to separate from the bearing seat 6 and exit the platform 1.

[0033] The bearing seat 6 transports the to-be-tested device 11 through the material feeding assembly 2, the positioning assembly 3, the testing assembly 4 and the material returning assembly 5 in sequence, and the to-be-tested device 11 is tested through the reciprocating transportation of the bearing seat 6.

[0034] In the preferred embodiment shown in the drawings, in order to realize the automation of the testing, the bearing seat 6 moves vertically relative to the platform 1, and the lower surface of the bearing seat 6 is provided with a pushing piece 61. Figure 3 The testing assembly 4 comprises a pressing block 41 and a movable part 42.

[0035] The pressing block 41 is arranged directly above the bearing seat 6 and moves vertically relative to the platform 1.

[0036] The movable part 42 moves horizontally relative to the bearing seat 6; the movable part 42 is L-shaped, and the end of the bottom transverse extension of the movable part 42 extends below the bearing seat 6 and is provided with a wedge slot 401; the push piece 61 is an inclined strip or a strip similar to an S shape; when the push piece 61 moves downward with the bearing seat 6 and is inserted into the wedge slot 401, the push piece 61 cooperates with the wedge slot 401 to move the movable part 42 along the inclined part of the push piece 61, so as to pull the movable part 42 close to the bearing seat 6, or the push piece 61 exits the wedge slot 401, and the movable part 42 moves away from the bearing seat 6 and moves back to the original position; a support member can be arranged on the platform 1, a guide rod is arranged on the support member, a spring is arranged on the guide rod, and the movable part 42 is connected to the guide rod, so that the movable part 42 can move back to the original position through the spring; the top end of the vertical extension of the movable part 42 extends to the side of the bearing seat 6; a row of insertion strips can be arranged on the top end of the movable part 42, and a spring is arranged between the row of insertion strips and the top end of the movable part 42; the row of insertion strips is transversely arranged with a plurality of detection heads 12; each detection head 12 corresponds to a joint on the to-be-tested member 11, moves horizontally with the movable part 42, and is in soft connection with the to-be-tested member 11 to perform detection, or the detection head 12 is disconnected from the to-be-tested member 11. When the pressing block 41 descends and presses the to-be-tested member 11 and the bearing seat 6, the push piece 61 is inserted into the wedge slot 401, the movable part 42 approaches the to-be-tested member 11, the detection head 12 is in soft insertion with the joint on the to-be-tested member 11, and the tail of each detection head 12 is connected to a detector to detect whether the to-be-tested member 11 is qualified. If the detection is qualified, the pressing block 41 can be lifted, the bearing seat 6 is also lifted and reset, and is transferred to the next station; if the detection is unqualified, the pressing block 41 continues to press downward and marks the surface of the to-be-tested member 11. Because the bearing seat 6 and the rotating disc 13 are provided with springs, and the row of insertion strips and the movable part 42 are also provided with springs, the spring between the row of insertion strips and the movable part 42 plays a buffering role; when the bearing seat 6 continues to descend due to unqualification, the row of insertion strips also descends relative to the movable part 42, so as to avoid that the detection head 12 on the row of insertion strips and the joint on the to-be-tested member 11 have a large height difference, and the detection head 12 pulls and damages the to-be-tested member 11; and because the detection head 12 and the joint are in soft insertion, damage can be avoided as much as possible.

[0037] In Figure 6 In a preferred embodiment shown in the drawings, in order to mark the unqualified to-be-tested member 11, the testing assembly 4 further comprises a marking head 43.

[0038] Wherein, the lower surface of the pressing block 41 is provided with a groove 402, the marking head 43 is arranged in the groove 402, and a spring is arranged between the marking head 43 and the groove top surface of the groove 402; the lower surface of the marking head 43 is provided with a convex block with a "FAIL" character. In the initial state, the lower surface of the marking head 43 and the lower surface of the pressing block 41 form a height difference; when it is detected that the to-be-tested piece 11 is unqualified, the pressing block 41 continues to descend, and the marking head 43 moves vertically relative to the pressing block 41 at the same time; the marking head 43 descends to make the lower surface of the marking head 43 flush with the lower surface of the pressing block 41, so that the lower surface of the marking head 43 contacts the to-be-tested piece 11 and marks on the surface of the to-be-tested piece 11, or the marking head 43 rises and resets at the same time as the pressing block 41. The principle of marking can be that the convex block forcibly extrudes the surface of the to-be-tested piece 11, or a heating mechanism can be arranged in the marking head 43, and the marking head 43 and the convex block are heated to heat-print the mark on the surface of the to-be-tested piece 11; other ways capable of realizing the marking function can also be adopted.

[0039] In Figure 5 In a preferred embodiment shown, since there is a certain difference in the falling position of each to-be-tested piece 11 when the to-be-tested piece 11 falls from the falling component 2 to the bearing seat 6, this affects the subsequent detection, and may cause that the joint on some to-be-tested pieces 11 cannot be normally soft-connected with the detection head 12, therefore, the positioning component 3 in the embodiment includes a pressing plate 31 and a sliding block 32.

[0040] Wherein, the pressing plate 31 is arranged vertically above the bearing seat 6 and moves vertically relative to the bearing seat 6, the pressing plate 31 descends and contacts the to-be-tested piece 11, the pressing plate 31 limits the to-be-tested piece 11 from leaving 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 on the positioning station of the platform 1 to drive the pressing plate 31 to move up and down; or other ways can also be adopted, which will be described in detail in subsequent embodiments.

[0041] The sliding block 32 is arranged on the side of the bearing seat 6 and moves horizontally relative to the bearing seat 6, and the sliding block 32 also moves horizontally reciprocatingly through a support, a guide rod and a spring, like the movable part 42. The sliding block 32 moves towards the to-be-tested piece 11 at the same time as the pressing plate 31 descends, the sliding block 32 abuts against and pushes the to-be-tested piece 11 to move in place in the bearing seat 6, or the sliding block 32 moves away from the to-be-tested piece 11 at the same time as the pressing plate 31 rises. Through the pressing and pushing of the to-be-tested piece by the pressing plate 31 and the horizontal movement of the to-be-tested piece 11 by the sliding block 32, the horizontal relative position and the vertical relative position of each to-be-tested piece 11 to the bearing seat 6 remain consistent after the to-be-tested piece 11 passes through the positioning station.

[0042] In Figure 5In a preferred embodiment shown, in order to realize the accurate positioning of the workpiece 11, the side of the workpiece 11 is provided with a flange 111, and the side provided with the flange 111 is provided with a joint; when the workpiece 11 is fed to the bearing seat 6, the flange 111 is away from the bearing seat 6, the slider 32 pushes the workpiece 11 to move horizontally relative to the bearing seat 6, so that the flange 111 abuts against the side plate of the bearing seat 6 and the workpiece 11 is moved to the position in the bearing seat 6, thereby ensuring that the horizontal relative position of each workpiece 11 to the bearing seat 6 is consistent.

[0043] In Figure 5 In a preferred embodiment shown, in order to realize the linkage of the pressing plate 31 and the slider 32, thereby avoiding the need for independent driving mechanisms for the pressing plate 31 and the slider 32 to realize the movement, the device further comprises a baffle 7, a first connecting rod 8 and a inclined rod 9.

[0044] The baffle 7 is arranged on the other side of the bearing seat 6 and opposite to the slider 32.

[0045] The first connecting rod 8 is connected at two ends to the baffle 7 and the slider 32 respectively.

[0046] The inclined rod 9 is arranged above the platform 1 and moves synchronously with the pressing plate 31; the inclined rod 9 is arranged obliquely relative to the surface of the platform 1, the inclined rod 9 is lowered and abuts against the baffle 7, the inclined rod 9 guides the baffle 7 to move away from the bearing seat 6 and drives the slider 32 to approach the bearing seat 6 through the first connecting rod 8, the principle of the movement of the baffle 7 guided by the inclined rod 9 is the same as that of the push piece 61. When the pressing plate 31 is lowered to press the workpiece 11, the inclined rod 9 is lowered and gradually pushes the baffle 7 to move backward, the baffle 7 moves backward and pulls the slider 32 to move forward through the first connecting rod 8, the slider 32 pushes the workpiece 11 to move horizontally, thereby realizing the linkage movement of the pressing plate 31 and the slider 32.

[0047] In Figure 5 In a preferred embodiment shown, the device further comprises a turntable 13.

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

[0049] The four bearing seats 6 are evenly arranged at the edges of the turntable 13; the feeding assembly 2, the positioning assembly 3, the testing assembly 4 and the discharging assembly 5 are evenly arranged at the 0°, 90°, 180° and 270° positions of the turntable 13 and are arranged one by one corresponding to the four bearing seats 6.

[0050] The driving assembly 14 is arranged below the platform 1 and is used to drive the turntable 13 to rotate, thereby realizing the cyclic switching of the four stations on the platform 1 through the rotation of the four bearing seats 6.

[0051] In Figure 5In a preferred embodiment shown, the material returning assembly 5 comprises a push plate 51, which is arranged on the side of the bearing seat 6 facing the center of the rotating disc 13; the material returning station is further provided with a slide, which is arranged on the side of the bearing seat 6, the push plate 51 horizontally moves and pushes the test piece 11 out of the bearing seat 6, and the test piece 11 is separated from the platform 1 through the slide to realize the material returning.

[0052] In order to realize the linkage of the pressing block 41, the pressing plate 31, the sliding block 32 and the push plate 51, so that the positioning assembly 3, the testing assembly 4 and the material returning assembly 5 can realize the linkage action through the same set of driving mechanism, the testing device further comprises a second connecting rod 15 and a third connecting rod 16.

[0053] The two ends of the second connecting rod 15 are respectively connected to the pressing plate 31 and the pressing block 41, and the end of the inclined rod 9 away from the platform 1 is connected to the second connecting rod 15.

[0054] The two 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 pressing block 41 drives it to descend, the pressing plate 31 will also descend through the second connecting rod 15; at the same time, the inclined rod 9 will also descend through the second connecting rod 15 along with the pressing block 41, and the descent of the inclined rod 9 will drive the baffle 7 to horizontally move, and the baffle 7 will drive the sliding block 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, so that when the sliding block 32 pushes the test piece 11 in the corresponding position to move to the position in the bearing seat 6, the push plate 51 pushes the test piece 11 in the corresponding position to separate from the bearing seat 6 and exit 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 arranged in the middle part of the platform 1.

[0055] In Figure 4 In a preferred embodiment shown, the material returning assembly 5 comprises a push plate 51, which is arranged on the side of the bearing seat 6 facing the center of the rotating disc 13; the material returning station is further provided with a slide, which is arranged on the side of the bearing seat 6, the push plate 51 horizontally moves and pushes the test piece 11 out of the bearing seat 6, and the test piece 11 is separated from the platform 1 through the slide to realize the material returning.

[0056] The two ends of the second connecting rod 15 are respectively connected to the pressing plate 31 and the pressing block 41, and the end of the inclined rod 9 away from the platform 1 is connected to the second connecting rod 15.

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

[0058] The sliding rod 23 is connected to the tongue depressor plate 22 at one end and extends vertically to below the platform 1 at the other end and is connected to the driving assembly 14; the sliding rod 23 moves downward intermittently under the driving of the driving assembly 14, the sliding rod 23 pulls the tongue depressor plate 22 to move synchronously, the tongue depressor plate 22 presses the test piece 11 and offsets the friction force between the test piece 11 and the friction block, so that the test pieces 11 are separated from the storage cylinder 21 one by one.

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

[0060] The motor 141 is arranged at the lower surface of the platform 1.

[0061] The rotating shaft 142 is arranged at the center of the rotating disc 13 and drives the rotating disc 13 to rotate, and the other end of the rotating shaft 142 extends to the lower side of the platform 1.

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

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

[0067] The main gear 143 rotates under the drive of the motor 141 and alternately matches with the first gear 144 and the second gear 145; the second gear 145 drives the slide rod 23 to intermittently move downward through the linkage gear set 147. When the main gear 143 first matches with the first gear 144 to rotate a quarter of a circle, it drives the rotating disc 13 to rotate a quarter of a circle, thereby driving each bearing seat 6 to move from the current station to the next station; when the main gear 143 rotates a quarter of a circle again, it is not linked with any gear; when the main gear 143 rotates a quarter of a circle again, it matches with the second gear 145, thereby making the blanking assembly 2 blank a piece of the measured piece 11; when the main gear 143 rotates a quarter of a circle again, it is full of a circle, at this time, it is not linked with any gear, until the main gear 143 rotates a circle again, it will match with the first gear 144 again. The above design can make the bearing seat 6 move to the next station and blank a piece of the measured piece 11 at the same time in the process of the main gear 143 rotating a full circle.

[0068] Working principle:

[0069] In the initial state, the bearing seat 6 of the blanking station is empty, and the bearing seats 6 of the other three stations are provided with the test pieces 11.

[0070] Firstly, the motor 141 drives the main gear 143 to rotate the first quarter of a circle in cooperation with the second driven gear 145, and the blanking assembly 2 blanks a test piece 11 onto the bearing seat 6 of the blanking station. At this time, the four stations are provided with the test pieces 11.
