During the pressing process of the optical emitting sub-module onto the circuit board, high assembly precision is required, which traditional manual assembly cannot meet. Therefore, there is an urgent need to propose a device to solve the above problems. Summary of the Invention

[0020] Example 2: A negative pressure adsorption pressing device includes: a platform 1, a base plate 2 located on one side of the platform 1, and a vacuum adsorption gun 3 located above the platform 1. A column plate 4 mounted on the base plate 2 is provided with a slide rail 51 and a slider 52 sleeved on the slide rail 51 on the side surface facing the platform 1. The vacuum adsorption gun 3 is provided on a support plate 61 of a bracket 6 mounted on the slider 52.

A sliding plate 10, an intermediate plate 11, and a guide rail plate 12 are sequentially arranged between the column plate 4 and the base plate 2. Two first guide rails 121 are parallel to each other on the surface of the guide rail plate 12 facing the intermediate plate 11 and are embedded in the grooves 111 of the intermediate plate 11.

[0021] The aforementioned bracket 6 is an L-shaped bracket.

[0022] The number of the first magnet 71 is two, located on the left and right sides of the column plate 4 respectively.

[0023] The first elastic element 13 is a spring, and its two ends are respectively connected to the hanging pins 19 located on the middle plate 11 and the guide rail plate 12.

[0024] The second elastic element 14 is a spring, and its two ends are respectively connected to the hanging pins 19 located on the slide plate 10 and the middle plate 11.

[0025] The working principle of this patent is as follows: First, the hanger 6 is placed in a high position and magnetically attached to the column plate 4. Then, the plate is placed at the designated position on the platform 1, and the workpiece is placed at the suction nozzle 31 of the vacuum suction gun 3. The negative pressure provided by the vacuum suction gun 3 causes the workpiece to be attached to the suction nozzle 31. Afterward, the tray 61 is manually moved down, causing the hanger 6 to slide along the slide rail 51 and disengage from the magnetic attachment. During the downward movement, the second micrometer 15 and the third micrometer 17 are adjusted to move the workpiece at the suction nozzle 31 in the XY axis direction to ensure that the workpiece does not press against the designated position on the plate surface. The positional deviation ensures the required assembly accuracy for workpiece installation. By adjusting the first micrometer 8, it is ensured that when the workpiece is pressed onto the plate surface, the first micrometer 8 and the baffle 9 just come into contact to limit the movement, thus preventing excessive clamping force during workpiece pressing and avoiding damage to the workpiece or plate. Afterward, the workpiece is pressed onto the designated position on the baffle surface with glue. At this point, the vacuum suction gun 3 stops suction, and the tray 61 is manually moved upward so that the hanger 6 and the column plate 4 are magnetically attracted together. Afterward, for the same batch of workpiece baffles, there is no need to recalibrate the micrometer, and the pressing between the workpiece and the plate can be carried out conveniently and efficiently.

[0026] When the above-mentioned negative pressure adsorption pressing equipment is used, when the workpiece installed at the vacuum adsorption gun nozzle moves to the surface of the plate, it is limited by the first micrometer making contact with the baffle, thus avoiding damage to the workpiece caused by excessive pressing force during workpiece pressing.

[0027] Furthermore, its design with a second and third micrometer allows for precise adjustment of the XY axis orientation of the workpiece at the vacuum suction gun nozzle, ensuring the required assembly accuracy for workpiece installation.

[0028] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
