Description

Technical Field

[0001] The utility model relates to the technical field of electronic modules, in particular to a fully automatic ejection mechanism for an electronic module. Background Art

[0002] An electronic module is a pre-designed collection of electronic components with specific functions, usually containing one or more electronic components, such as integrated circuits, resistors, capacitors, inductors, transistors, diodes, sensors, etc.

[0003] For example, a Chinese patent with the publication (announcement) number CN106893995B discloses an electronic module ejection mechanism for ejecting an electronic module from a carrier. The electronic module is fixed to the carrier by an adhesive layer, and includes: a rigid ejector pin, an elastic ejector pin, and a mounting plate. The rigid ejector pin and the elastic ejector pin are both mounted on the mounting plate. The rigid ejector pin and the elastic ejector pin act together on the electronic module to separate it from the carrier. The elastic ejector pin includes an elastic portion and a rigid portion, and the elastic portion is disposed adjacent to the mounting plate. The length of the rigid ejector pin is equal to the length of the elastic ejector pin in a natural state. The rigid ejector pin and the elastic ejector pin are both disposed corresponding to the edge position of the electronic module, and at least one rigid ejector pin and at least one elastic ejector pin are disposed along the length direction of the electronic module.

[0004] Although the above technical solution solves the corresponding technical problem, the above technical solution still has the following defects:

[0005] The above technical solution uses rigid ejector pins and elastic ejector pins to eject the electronic module, and the contact surface between the rigid ejector pins and the electronic module is small. At the same time, since the ejection force of the rigid ejector pins and the elastic ejector pins on the electronic module is inconsistent, the electronic module may be deflected, thereby affecting the ejection of the electronic module. Utility Model Content

[0006] The utility model aims to provide a fully automatic ejection mechanism for an electronic module. When the electronic module body needs to be ejected, it is only necessary to turn on the servo motor, and the servo motor drives the cam on the driving shaft to rotate, so that the driving seat can be squeezed at different radii through the cam. When the cam squeezes the driving seat with most of the radius, the ejection plate on the connecting rod can be driven to move upward through the driving seat, and the electronic module body is lifted up by the ejection plate. Moreover, since the ejection plate and the bottom of the electronic module body can be in parallel and large-area contact, the deflection of the electronic module body when ejecting is avoided, thereby ensuring the convenient ejection of the electronic module body.

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] A fully automatic ejection mechanism for an electronic module, comprising:

[0009] Modular vehicles;

[0010] An electronic module body placed on the module carrier;

[0011] An ejection assembly for ejecting the electronic module body, the ejection assembly includes an ejection structure arranged at the bottom of the module carrier, the top of the module carrier is also fixedly connected to a mounting frame, and a driving structure for driving the ejection structure is installed on the ejection structure and at a position corresponding to the mounting frame.

[0012] The above-mentioned fully automatic ejection mechanism of the electronic module, wherein the ejection structure includes a driving seat, both sides of the top of the driving seat are fixedly connected with connecting springs, the top of the driving seat is fixedly connected to the bottom of the module carrier through the connecting springs, and the top of the driving seat is also fixedly connected with two symmetrically arranged connecting rods, and the tops of the two connecting rods are fixedly connected through an ejection plate.

[0013] The above-mentioned fully automatic ejection mechanism of the electronic module, wherein the driving structure includes a driving frame fixedly connected to the mounting frame, a servo motor is fixedly connected to the side of the driving frame, a driving shaft is fixedly connected to the output shaft of the servo motor, and a cam is fixedly connected to the driving shaft.

[0014] In the above-mentioned fully automatic ejection mechanism for electronic modules, one end of the driving shaft away from the servo motor is rotatably connected to the side surface of the inner wall of the driving frame through a limit bearing.

[0015] In the above-mentioned fully automatic ejection mechanism of the electronic module, both sides of the driving seat are fixedly connected with limit sliders, and both sides of the inner wall of the mounting frame and corresponding to the positions of the two limit sliders are provided with limit sliding grooves matching the limit sliders.

[0016] In the above-mentioned fully automatic ejection mechanism of the electronic module, the side of the limiting sliding block close to the limiting sliding groove moves through the limiting sliding groove, extends to the inside of the limiting sliding groove, and is slidably connected to the inner wall of the limiting sliding groove.

[0017] The above-mentioned fully automatic ejection mechanism for electronic modules, wherein a buffer pad is fixedly connected to the top of the ejection plate.

[0018] The utility model has at least the following beneficial effects:

[0019] In the utility model, an electronic module fully automatic ejection mechanism is realized. When the electronic module body needs to be ejected, it is only necessary to turn on the servo motor, and the servo motor drives the cam on the driving shaft to rotate, so that the driving seat can be squeezed at different radii through the cam. When the cam squeezes the driving seat with most of the radius, the ejection plate on the connecting rod can be driven to move upward through the driving seat, and the electronic module body is lifted up by the ejection plate. Moreover, since the ejection plate and the bottom of the electronic module body can be in parallel and large-area contact, the deflection of the electronic module body when ejecting is avoided, thereby ensuring the convenient ejection of the electronic module body.
