Fig. 5 is a schematic structural view of the stopper 50 of the clamping device 100 for the optical module 200 according to one embodiment of the present invention. The present invention provides a clamping device 100 for an optical module 200, as shown in fig. 1, which in one embodiment includes a cylinder 10, a cylinder fixing plate 20, a cylinder push plate 30, a press block assembly 40, a stopper 50, a temperature control module 60, and a lever bracket 70. The cylinder 10 includes a cylinder body 11 and a plunger 12, and expansion and contraction of the plunger 12 with respect to the cylinder body 11 are controlled by air pressure. The cylinder fixing plate 20 is fixedly provided to fix the cylinder 11, and a stationary member is usually provided when the clamping device 100 is used, and the cylinder fixing plate 20 may be fixedly connected to the stationary member. The cylinder push plate 30 is fixedly connected to the plunger 12, such as by screws. The press block assembly 40 includes an optical module press block 41, and the optical module press block 41 is used to press-contact the optical module 200. As shown in fig. 4, the press block assembly 40 is connected with the cylinder push plate 30 through a first fastener 101, the first fastener 101 passes through the cylinder push plate 30 and is in threaded connection with the press block assembly 40, and a first compression spring 102 abutting between the cylinder push plate 30 and the press block assembly 40 is sleeved on the first fastener 101. The limiting block 50 is fixedly arranged below the pressing block assembly 40 and is used for placing the optical module 200 and limiting the position of the optical module 200. As before, the stopper 50 may be fixed to the stationary member. The temperature control module 60 is located below the limiting block 50 and is used for controlling the temperature of the optical module 200. The two ends of the lever bracket 70 are respectively abutted with the pressing block assembly 40 and the temperature control module 60, namely, the lever bracket 70 is in rotary connection with a fixed part through a rotary shaft 71, and the upper surfaces of the two ends of the lever bracket 70 are respectively abutted with the pressing block assembly 40 and the temperature control module 60. The cylinder 10 is used for controlling the plunger 12 to extend when the optical module 200 needs to be compressed, and then driving the pressing block assembly 40 to move downwards and the temperature control module 60 to move upwards, so that the optical module pressing block 41 abuts against the top surface of the optical module 200, and the temperature control module 60 contacts with a heat dissipation surface at the bottom surface of the optical module 200 (see fig. 3). Of course, when the optical module 200 is not required to be compressed, the plunger 12 is retracted, and neither the optical module pressing block 41 nor the temperature control module 60 is in contact with the optical module 200, see the state of fig. 2. As shown in fig. 5, the stopper 50 is provided with a stopper through hole 51 penetrating in the length direction of the optical module 200, the bottoms of both sides of the stopper through hole 51 are provided with a convex strip 52, as shown in fig. 2, the top surface of the convex strip 52 is used for placing the optical module 200, and the stopper through hole 51 also partially penetrates the upper and lower surfaces of the stopper 50 so as to be in contact with the press block assembly 40 and the temperature control module 60. Generally, as shown in fig. 2, the portion of the temperature control module 60 contacting the optical module 200 has a separate boss, and the distance between the two protruding strips 52 may be slightly larger than the width of the boss, so that the boss extends between the two protruding strips 52 and contacts the heat dissipation surface of the optical module 200.

In a specific operation, the plunger 12 of the control cylinder 10 extends to push the cylinder pushing plate 30 to move downwards, and the pressing block assembly 40 is suspended by the cylinder pushing plate 30, so that the pressing block assembly 40 moves downwards along with the cylinder pushing plate 30 under the action of gravity. When the pressing block assembly 40 moves down to touch one end of the lever bracket 70, the cylinder pushing plate 30 starts to compress the first compression spring 102 to continuously push the pressing block assembly 40 to move down so as to press one end of the lever bracket 70, so that the other end of the lever bracket 70 is tilted up, and the temperature control module 60 is lifted up, so that the temperature control module 60 is in contact with the heat dissipation surface of the optical module 200. When the cylinder pushing plate 30 moves downwards, the optical module pressing block 41 also moves downwards until the optical module pressing block 41 contacts with the upper surface of the optical module 200, and then the first compression spring 102 at the optical module pressing block 41 is compressed, so that the optical module pressing block 41 is further pushed to be pressed on the optical module 200. The process of decompressing is the opposite to the above process and will not be described here again.

In this embodiment, the air cylinder 10 is used to control the optical module pressing block 41 and the temperature control module 60 to clamp the upper and lower surfaces of the optical module 200 synchronously, and because the force provided by the air cylinder 10 can be controlled, appropriate pressure can be applied to the optical module 200 after debugging, the optical module 200 is simply and efficiently crimped by programmed control, and a special method is not needed to screw down or use an elbow clamp, so that the optical module 200 is not crushed, and the surface quality of the optical module 200 can be ensured. The temperature control module 60 is directly contacted with the radiating surface of the optical module 200, so that the temperature raising and lowering efficiency is ensured, the whole crimping process is simple and efficient, and the time cost is saved.

Further, due to the arrangement of the first compression spring 102, when the downward thrust acts on the optical module 200, the pressure does not suddenly increase, but the pressure buffered by the spring is provided, which is beneficial to protecting the surface of the optical module 200 from being lost and ensuring the surface quality.

In this embodiment, the raised strips 52 for placing the optical module 200 are provided, so that the upper surface of the temperature control module 60 is lower than the lower surface of the optical module 200, and therefore the two are not contacted, thereby preventing the optical module 200 from being scratched during the plugging process.

Further, the position of the optical module 200 is effectively limited by the arrangement of the protruding strips 52, and the optical module 200 can be easily inserted into the interface of the circuit board of the device to be tested only by aligning the position of the limiting structure with the interface of the circuit board of the device to be tested.

As shown in fig. 5, the front portion of the stopper 50 is further provided with an insertion opening 53 expanding from back to front for guiding the insertion of the optical module 200.
