The vertical plate 12 and the side plates 13 are fixed to the front end of the bottom plate 11, and the pivot block 14 is located at the rear end of the bottom plate 11. The bottom plate 11 is horizontally arranged, the vertical plate 12 and the side plates 13 are arranged vertically, and the lower ends are fixed to the upper surface of the bottom plate 11 respectively. The front ends of the two side plates 13 are vertically fixedly connected to the left and right ends of the vertical plate 12, and the three form a U shape. The pair of pivot blocks 14 are arranged opposite to each other on the left and right sides, and a part of each pivot block 14 is fixed to the bottom plate 11, and the other part is fixed to the test device 200. The pivot block 14 is divided into two parts for easy manufacturing. It includes a first pivot block 141 and a second pivot block 142 that are attached to each other. The first pivot block 141 is provided with a circular hole 143 that passes through the first pivot block 141 on the left and right sides. The second pivot block 142 is provided with a movable hole 144 that passes through the second pivot block 142 on the left and right sides. The movable hole 144 extends downward and backward in an inclined manner. The inner wall of the movable hole 144 is provided with an arc surface 145 and an inclined surface 146 located in front of the arc surface 145. The arc surface 145 is concave backward. In other embodiments, the pivot block 14 is fixed to one of the bottom plate 11 and the testing device 200 separately.

[0023] The electric push rod 20, also known as a linear drive, is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. The front end of the electric push rod 20 is fixedly connected to the vertical plate 12 of the main seat body 10 through a bracket 21, and the bracket 21 is a U-shaped sheet. The bracket 21 is fixed to the vertical plate 12, and the electric push rod 20 and the bracket 21 are rotatably connected. The front end of the electric push rod 20 can rotate up and down around the bracket 21. The front end of the electric push rod 20 is provided with a connecting rod 22 that can be telescoped forward and backward.

[0024] The floating connection mechanism 30 is connected between the connecting rod 22 and the deflection mechanism 40. The floating connection mechanism 30 includes a first connection block 31, a second connection block 32 located behind the first connection block 31, and a spring (not shown) connected between the first connection block 31 and the second connection block 32. The first connection block 31 is rotationally connected to the connecting rod 22, and the second connection block 32 is rotationally connected to the deflection mechanism 40.

[0025] The deflection mechanism 40 includes a deflection block 41, an upper fixed block 42, a lower fixed block 43, a front rotating shaft 44, an upper rotating shaft 45 and a lower rotating shaft 46. The deflection block 41 is a long strip structure extending left and right, and includes a main body 411 and a boss 412 extending forward from the upper end of the main body 411. The cross section of the main body 411 is roughly triangular. The left and right sides of the main body 411 are convexly provided with a circular shaft 413, which is inserted into the circular hole 143 of the pivot block 14 and can rotate in the circular hole 143.

[0026] The front rotating shaft 44 is disposed through the front end of the deflection block 41 and the second connecting block 32 , so that the two can rotate relative to each other.

[0027] The upper fixing block 42 and the lower fixing block 43 are fixed together vertically, and a concave-convex structure that fits mutually is provided between the upper fixing block 42 and the boss 412. The concave-convex structure is connected together by the upper rotating shaft 45, so that the upper fixing block 42 and the lower fixing block 43 can rotate relative to the boss 412. In other embodiments, the upper fixing block 42 and the lower fixing block 43 are provided as one body.

[0028] The lower rotating shaft 46 is fixed to both ends of the lower fixing block 43 , and the outer end thereof extends into the movable hole 144 of the pivot block 14 , and can move along the arc surface 145 in the movable hole 144 .

[0029] The clamping blocks 50 are installed on the lower fixed block 43 at intervals. Electrodes are arranged on the clamping blocks 50 . The clamping blocks 50 are used to vertically press down the laser chip 201 to achieve stable clamping of the laser chip 201 and ensure reliable electrical contact between the electrodes and the laser chip 201 .

[0030] The auxiliary device 60 is installed on the test device 200 and is located below the deflection mechanism 40. It includes an auxiliary block 61, a plurality of springs (not shown) installed on the auxiliary block 61, and a stroke detector (not shown) installed on the auxiliary block 61. The spring presses upward on the deflection block 41 to provide the deflection block 41 with a tendency to maintain upward movement. The stroke detector is used to monitor the state of the deflection block 41 moving to the final position in real time and to feed back this information to the system in real time.

[0031] The working principle of the laser chip automatic press-fitting mechanism 100 of the present invention is as follows: First, a row of laser chips 201 are precisely and orderly arranged on the test device 200 at intervals by manual or precision manipulator operation to ensure that each laser chip 201 can be tested independently and accurately; Then, the connecting rod 22 of the electric push rod 20 extends backward, driving the floating connection mechanism 30 to drive the deflection mechanism 40 to rotate. During this process, the rear end of the electric push rod 20 rotates relative to the main seat body 10, and the deflection block 41 rotates around the circular axis 413. The lower rotating shaft 46 is limited by the movable hole 144 to move downward and backward. The upper fixed block 42 and the lower fixed block 43 follow the deflection block 41 to move downward until the pressing blocks 50 of the lower fixed block 43 press downward on the laser chip 201, thereby pressing and powering the laser chip 201, so that the testing device 200 can test various performance indicators of the laser chip 201 to ensure that its functions and specifications meet the standards. Finally, after the test is completed, each component returns to its initial position under the drive of the electric push rod 20, waiting for the next press-fitting operation.

[0032] The laser chip automatic press-fitting mechanism 100 of the present invention can automatically and efficiently complete the batch press-fitting operation of the laser chips 201, significantly reducing the labor intensity and workload of workers and greatly improving work efficiency. At the same time, it can ensure the precise control of the press-fitting position and pressure, effectively avoiding the uncertainty in the traditional method, thereby further improving the production efficiency and the stability and reliability of product quality.
