[0036] Embodiment one

[0037] As Figures 1 to 4 shown, the clamping jig for optical element detection includes a first flap 10 and a second flap 20, the first side of the first flap 10 is pivotally connected with the first side of the second flap 20, the second side of the first flap 10 is selectively connected with the second side of the second flap 20 through a connecting structure, when the first flap 10 and the second flap 20 are closed, a containing area for containing the optical element to be detected is formed between the first flap 10 and the second flap 20, the clamping jig further includes a buffer block 30, the buffer block 30 is located at the circumferential side of the containing area.

[0038] By pivotally connecting the first side of the first flap 10 with the first side of the second flap 20, the pivot angle of the first flap 10 and the second flap 20 can be adjusted to change the included angle between the first flap 10 and the second flap 20, so that the first flap 10 and the second flap 20 can be switched between the closed state and the open state, which is convenient to operate. By selectively connecting the second side of the first flap 10 with the second side of the second flap 20 through the connecting structure, when operating, the second side of the first flap 10 and the second side of the second flap 20 can be connected or not connected by adjusting the connecting structure, when not connected, the first flap 10 and the second flap 20 can pivot to facilitate placing the optical element to be detected into the containing area or taking out the optical element in the containing area after detection; after the optical element to be detected is placed in the containing area, the first flap 10 and the second flap 20 can be closed, and then the second side of the first flap 10 and the second flap 20 is fixedly connected through the connecting structure, so that the first flap 10 and the second flap 20 remain in the closed state, thereby realizing the clamping and fixing of the optical element, which is convenient for subsequent detection work. By arranging the buffer block 30 at the circumferential side of the containing area, the buffer block 30 can effectively absorb and disperse the external force impact generated in the detection process, realize the gentle clamping of the optical element, avoid the small scratches or stress damage caused by hard contact, and be suitable for the detection of precision optical elements.

[0039] In addition, the clamping jig for optical element detection is simple to operate, easy to operate, improves operation efficiency, improves the efficiency and reliability of the optical element in the detection process, effectively improves the detection accuracy, provides solid support for the quality control of the optical element, and meets the strict detection requirements.

[0040] It should be noted that the first side and the second side are a pair of opposite sides, as shown in Figure 2 The left side of the first flap 10 is pivotally connected to the left side of the second flap 20, and the right side of the first flap 10 is selectively connected to the right side of the second flap 20 through the connecting structure.

[0041] Specifically, the first side of the first flap 10 is pivotally connected to the first side of the second flap 20 through the shaft 80, the first side of the first flap 10 has a through hole, and the first side of the second flap 20 also has a through hole, the through hole of the first flap 10 and the through hole of the second flap 20 are coaxially arranged, and then the shaft 80 passes through the through holes of the first flap 10 and the second flap 20 in sequence to realize the pivotal connection of the two, in the specific embodiment of the present application, the both ends of the shaft 80 are provided with a stop ring to realize limiting, avoiding the shaft 80 from coming out of the first flap 10 and the second flap 20.

[0042] Optionally, the middle of the shaft 80 can also be installed with a torsional spring, so that when the first flap 10 and the second flap 20 are opened, the torsional spring can provide a elastic force to make the first flap 10 can be automatically opened.

[0043] As shown in Figure 1 The accommodation area is divided into a first accommodation area 11 and a second accommodation area 21, the first flap 10 has the first accommodation area 11, the second flap 20 has the second accommodation area 21, and the buffer block 30 is arranged on the first flap 10 and around the circumference of the first accommodation area 11. The first accommodation area 11 is actually a through hole, and the hole wall surface of the through hole is stepped to form a surface abutting against the outer peripheral area of one side surface of the optical element. Similarly, the second accommodation area 21 is actually a through hole, and the hole wall surface of the through hole is stepped to form a surface abutting against the outer peripheral area of the other side surface of the optical element. When the first flap 10 and the second flap 20 are closed, the first accommodation area 11 and the second accommodation area 21 form the entire accommodation area, and the shape and size of the accommodation area are matched with the shape and size of the optical element.

[0044] By Figure 1As shown, the second flap 20 is also provided with a guide groove on the side surface facing the first flap 10, the guide groove is two, the two guide grooves are respectively arranged on the two sides of the second accommodating area 21, and one end of the guide groove extends to the second accommodating area 21, and the other end of the guide groove extends to the edge of the second flap 20. By setting the guide groove, the optical element can be placed in the accommodating area or taken out from the accommodating area.

[0045] In the present application, the optical element includes one of a lens and a waveguide sheet, and of course can be other precise optical elements, which are not limited in the present application.

[0046] Specifically, the side surface of the first flap 10 facing the second flap 20 has a sink, and the buffer block 30 is accommodated in the sink. The buffer block 30 avoids the first accommodating area 11, and the shape of the buffer block 30 is quadrilateral. The sink provides a setting space for the buffer block 30. In actual application, the side surface of the buffer block 30 away from the bottom of the sink can be flush with the side surface of the first flap 10 facing the second flap 20, so as to avoid the buffer block 30 being too protruding. Of course, the side surface of the buffer block 30 away from the bottom of the sink can be slightly higher than the side surface of the first flap 10 facing the second flap 20. Since the buffer block 30 is made of elastic material, such as PTFE, PP and the like. Therefore, the buffer block 30 being slightly higher than the sink will not affect the closure of the first flap 10 and the second flap 20.

[0047] As shown in Figure 1 The clamping jig further includes a fixing member 50, and the buffer block 30 is fixedly connected with the first flap 10 through the fixing member 50. In the embodiment, the fixing member 50 is a screw, and the four corner positions of the buffer block 30 are respectively fixedly connected with the first flap 10 through one screw. In this way, the fixing member 50 can realize the limiting fixation of the buffer block 30, so as to avoid the risk of the buffer block 30 falling off during the opening of the first flap 10.

[0048] As shown in Figure 3 and Figure 4 The clamping jig further includes a buffer compression elastic element 40, and the buffer compression elastic element 40 is supported between the buffer block 30 and the bottom of the sink. Specifically, the buffer block 30 and the bottom of the sink are provided with corresponding grooves, and the buffer compression elastic element 40 is arranged at the grooves. The buffer compression elastic element 40 can be a spring with appropriate elastic modulus or a silica gel gasket, so that the buffer compression elastic element 40 has appropriate supporting force, so as to ensure that the optical element can be clamped without gap when the first flap 10 and the second flap 20 are closed, so as to ensure that the optical element will not shake during detection, which is beneficial to increase the detection precision. At the same time, the clamping force can be adjusted through the buffer compression elastic element 40, so as to prevent the optical element from being damaged due to excessive clamping force.

[0049] As shown in Figure 1 One of the first flap 10 and the second flap 20 has a plurality of positioning pins 24, and the other of the first flap 10 and the second flap 20 has a plurality of positioning grooves 12, and the plurality of positioning pins 24 and the plurality of positioning grooves 12 are arranged one by one. In the embodiment, two spaced positioning pins 24 are arranged on the second flap 20, and the two positioning pins 24 are respectively arranged in the two positioning holes 23 of the second flap 20, and the positioning pins 24 are located on the side of the second accommodating area 21 away from the pivoting side of the first flap 10; the second flap 20 has two positioning grooves 12, and the positioning grooves 12 are located on the side of the first accommodating area 11 away from the pivoting side of the second flap 20. When the first flap 10 and the second flap 20 are closed, the positioning pins 24 are inserted into the positioning grooves 12, which are used for positioning the rotating direction of the first flap 10 and the second flap 20, ensuring that the two are aligned, ensuring the accuracy of the detection position, and helping to ensure the stability of the detection.

[0050] Specifically, the connecting structure includes one of a buckling structure and a clamping structure, and in the embodiment, the connecting structure is the buckling structure. The buckling structure includes a buckling 61, a buckle plate 63 and an elastic member 64, the buckling 61 is rotatably connected to one of the first flap 10 and the second flap 20 through a shaft structure 62, and the buckling 61 has a buckling part 611; the buckle plate 63 is fixedly connected to the other of the first flap 10 and the second flap 20, and the buckling part 611 is used for clamping connection with the buckle plate 63; the elastic member 64 is supported between the buckling 61 and the flap rotatably connected to the buckling 61, and the elastic member 64 is located on the side of the pivoting position of the buckling 61 away from the buckling part 611.

[0051] In the embodiment, the second side of the first flap 10 has a protruding plate segment, the protruding side of the plate segment has a groove for accommodating at least a part of the press buckle 61, the press buckle 61 and the plate segment have through holes corresponding to each other, and the shaft structure 62 passes through the through holes to rotatably connect the press buckle 61 with the first flap 10. The buckle plate 63 is fixedly connected with the side surface of the second flap 20 facing the first flap 10 by screws, and the outer peripheral area of the second side of the second flap 20 has a notch 22, the buckle plate 63 is arranged corresponding to the notch 22, that is, the projection of the buckle plate 63 on the second flap 20 partially coincides with the notch 22. The arrangement of the press buckle structure makes the opening and closing of the clamping jig more convenient, is suitable for occasions where the optical element is frequently replaced, improves the convenience of operation and the efficiency of detection. At the same time, it also reduces the wear of the clamping jig caused by frequent operation, prolongs the service life of the clamping jig. The elastic member 64 is supported between the press buckle 61 and the first flap 10, and the press buckle 61 and the first flap 10 have grooves corresponding to each other to leave accommodation space for the elastic member 64 and form a limit for the elastic member 64. The elastic member 64 can adopt a spring with appropriate elastic coefficient, and the elastic member 64 has a certain pre-tightening force. After the first flap 10 and the second flap 20 are closed, the elastic member 64 can be compressed by pressing the press buckle 61, the press buckle 61 is rotated, the buckling part 611 of the press buckle 61 is separated from the stop state with the buckle plate 63, so that the first flap 10 can be opened; when closing, press the press buckle 61, close the two flaps, release the press buckle 61, and under the pre-tightening force of the elastic member 64, the press buckle 61 is buckled with the buckle plate 63, which is convenient and efficient.

[0052] As shown in Figure 4 The buckling part 611 is used for clamping connection with the buckle plate 63, and the buckling end of the buckling part 611 is bent inward to form an L-shaped buckling part 611, and the bent part of the L-shaped buckling part 611 has a first abutting surface 6111, which is part of the inner side surface of the bent part. The side of the buckle plate 63 away from the press buckle 61 has a second abutting surface 631, and the first abutting surface 6111 and the second abutting surface 631 are in contact, so that the buckling part 611 and the buckle plate 63 are in stop cooperation in the dismounting direction, realizing the clamping connection of the two.

[0053] In the embodiment, the first abutting surface 6111 is parallel to one of the first flap 10 and the second flap 20, and the second abutting surface 631 is parallel to the other one of the first flap 10 and the second flap 20. Specifically, the first abutting surface 6111 is parallel to the first flap 10, and the second abutting surface 631 is parallel to the second flap 20. Such arrangement is conducive to ensuring the stability of the clamping connection and ensuring the connection strength.

[0054] Embodiment two

[0055] As shown in Figures 5 to 7As shown, a clamping fixture for optical element inspection according to Embodiment 2 is described.

[0056] The difference between this embodiment and Embodiment 1 is that the setting angles of the first abutment surface 6111 and the second abutment surface 631 are different.

[0057] Specifically, the first contact surface 6111 is set at an acute or obtuse angle to one of the first flap 10 and the second flap 20, and the second contact surface 631 is set at an acute or obtuse angle to the other of the first flap 10 and the second flap 20.

[0058] In this embodiment, both the first abutment surface 6111 and the second abutment surface 631 are inclined surfaces. That is, the first abutment surface 6111 is set at an acute or obtuse angle with the first flap 10, and the second abutment surface 631 is set at an acute or obtuse angle with the second flap 20. By setting the first abutment surface 6111 and the second abutment surface 631 as inclined surfaces, they can play a guiding role. When the first flap 10 and the second flap 20 are closed, the inclined surfaces can guide the fastening part 611 to engage with the stop plate 63. In addition, after the first flap 10 and the second flap 20 are closed, under the elastic force of the elastic member 64, the buckle 61 will have a tendency to rotate. When the inclined surfaces are pressed, the contact area usually increases, and the force on the buckle plate 63 and the buckle 61 is better than when there is a flat contact.

[0059] Example 3

[0060] like Figures 8 to 10 As shown, a clamping fixture for optical element inspection according to Embodiment 3 is described.

[0061] The difference between this embodiment and Embodiment 1 lies in the connection structure. In this embodiment, the connection structure is a snap-fit ​​structure.

[0062] like Figure 8 As shown, the engaging structure includes an engaging body 71 and a slot 72. The engaging body 71 is slidably connected to one of the first flap 10 and the second flap 20, and the engaging body 71 has an engaging portion 711. The other of the first flap 10 and the second flap 20 has a slot 72, and the engaging portion 711 selectively engages with the slot 72 in the disassembly direction. In this embodiment, the engaging body 71 is slidably connected to the first flap 10, and the second flap 20 has a slot 72.

[0063] like Figure 10As shown, the two sides of the clamping body 71 are respectively installed in the groove of the first flap 10 through a compression screw 74, the position where the first flap 10 is connected with the compression screw 74 is a through hole, and the surface of the clamping structure facing the second flap 20 is provided with a protruding clamping part 711. The clamping body 71 can linearly slide in the groove, thereby driving the clamping part 711 to linearly move. The compression screw 74 is further sleeved with a spring 73 to provide a certain locking force. When the first flap 10 and the second flap 20 are closed, the clamping part 711 can extend into the clamping groove 72 and move to the right to the state of being in abutment with the clamping groove 72, so as to realize limiting. When it is needed to open the clamping jig, the compression screw 74 is pressed to compress the spring 73, so that the clamping part 711 is separated from the abutment state with the clamping groove 72, that is, the opening action can be realized.

[0064] Specifically, the clamping part 711 is L-shaped, and the clamping groove 72 is an L-shaped groove. By reasonably planning the shapes of the clamping part 711 and the clamping groove 72, the cooperation of the two is facilitated, and the switching between the abutment state and the non-abutment state is facilitated.

[0065] Specifically, the clamping part 711 is one or more. When the clamping part 711 is multiple, the clamping groove 72 is multiple, and the multiple clamping grooves 72 correspond to the multiple clamping parts 711 one by one. In this embodiment, the clamping part 711 and the clamping groove 72 are both two. Of course, different numbers can also be set according to actual conditions, and the present application does not make any limitation.

[0066] In summary, the clamping jig for optical element detection provided by the present application forms a containing area through the closure of the first flap 10 and the second flap 20, which is used to place the optical element to be detected. At the same time, through the setting of the buffer block 30, accidental damage of the optical element during the detection process is effectively avoided, and the detection accuracy and the safety of the optical element are improved. Through the flexible design of the connecting structure, the operation of the clamping jig is more convenient, and the detection efficiency is improved. The scheme of the present application not only improves the actual effect of optical element detection, but also greatly reduces the element loss in the detection process, and has significant economic benefits and application benefits.

[0067] In practical application, the clamping jig can be widely applied to the manufacturing, research and development and quality control links of optical elements, which not only improves the detection efficiency and reduces the human operation errors, but also ensures the accuracy and safety of the optical element detection, and is suitable for various high-precision and high-standard optical element detection.
