Description

Discharge push rod mechanism of laser marking machine

technical field

The invention relates to the technical field of ceramic product production, in particular to a discharge push rod mechanism of a laser marking machine.

Background technique

LTCC products are ceramic products produced by LTCC technology. LTCC products are widely used in the integrated and modular production of electronic components due to their excellent electronic, mechanical and thermal characteristics. The current production process of LTCC products is as follows: Substrate and original device packaging, laser marking, cutting, testing, packaging and shipping. Among them, the marking of LTCC products after packaging is mainly realized by laser marking equipment. The main structure of laser marking machines commonly used in laser stations includes feeding boxes. , feeding push rod mechanism, printing and detection area, discharge push rod mechanism and material receiving box, wherein the discharge structure includes the discharge push rod mechanism, but the discharge structure of the laser marking machine in the prior art, its push head pressure It is on the upper surface of the LTCC product and is pulled forward by the static friction between them. Since the push head of the push rod of the discharge push rod mechanism is small and its position is fixed, the contact surface between the push head and the product is small, and the static friction is Under certain circumstances, the pressure between the push head and the product increases, and the surface of the product is easily scratched; while the push head is small, when the LTCC product with a certain curvature passes under the push head, it is easy to cause the push head to be out of contact. Empty push or misalignment of LTCC products, and misalignment can easily lead to skewing of the product during travel, which can easily lead to scratches on the product and its surroundings, resulting in material damage and other problems.

Contents of the invention

In view of the small push head in the discharge push rod mechanism in the prior art, it is easy to cause the surface of the LTCC product to be scratched. When the LTCC product with a certain degree of curvature passes under the push head, it is easy to cause the push head to not touch the LTCC product and appear. Empty push or dislocation, and dislocation will easily cause material damage and other problems. The invention provides a discharge push rod mechanism of a laser marking machine. The discharge push rod mechanism can prevent the surface of LTCC products from being scratched and has a certain degree of curvature. When the advanced LTCC product passes under the push head, the push head can accurately touch the LTCC product, the probability of material damage due to empty push or misalignment is small, and the product quality is stable.

A discharge push rod mechanism of a laser marking machine, which includes a push rod, one end of the push rod is provided with a push head, the other end of the push rod is installed on a push rod base, and the push rod base is fixed Installed on the piston rod of the first lifting cylinder, the first lifting cylinder is fixed on the slider of the translation slide rail, characterized in that:

A push plate is installed on the push head of the push rod, and the bottom surface of the push plate corresponds to the top surface of the LTCC product; the cross-sectional area of the push plate is larger than the cross-sectional area of the push head.

It is further characterized by:

A waist-shaped hole is arranged on the push rod base, and the other end of the push rod is installed in the waist-shaped hole.

With the above-mentioned structure of the present invention, a push plate is installed on the push head of the discharge push rod mechanism, and the cross-sectional area of the push plate is larger than the cross-sectional area of the push head, which can greatly increase the contact between the cover plate and the upper end surface of the LTCC product The area, on the one hand, reduces the pressure between the original push head and the product, effectively avoiding the product surface from being scratched, and on the other hand, ensures that the push head can be firmly in contact with the top surface of the LTCC product with a certain curvature, avoiding empty push Or misalignment problem occurs, and the installation position of the push rod can be adjusted through the waist-shaped hole, so that the push head of the push rod can correspond to the middle position of the LTCC product, thereby avoiding the position deviation caused by the force deviation of the product during the track movement Shifting further avoids the dislocation of LTCC products in the process of being pushed, and further ensures the quality of the products.

Detailed ways

As shown in Figure 1 and Figure 2, a discharge push rod mechanism of a laser marking machine includes a push rod 1, one end of the push rod 1 is provided with a push head 2, and the other end of the push rod 1 is installed on the push rod base Seat 3, the push rod base 3 is fixedly installed on the piston rod of the first lift cylinder 4, the first lift cylinder 4 is fixed on the slider of the translation slide rail 5, and the push plate 6 is installed on the push head 2 of the push rod 1, and the push plate 6 is installed on the push head 2 of the push rod 1. The bottom surface of the pressing plate 6 corresponds to the top surface of the LTCC product 7; the area of the cross-section of the pushing plate 6 is larger than that of the push head 2, the push rod base 3 is provided with a waist-shaped hole 8, and the other end of the push rod 1 passes through a screw 81 Installed in the waist hole 8;
