Abstract

The utility model discloses a claw mechanism for plastic-sealed products with variable step distance, which comprises a base plate (1), on which two linear slide rails (2) are fixedly connected, and two linear slide rails (2 ) are movably connected with several claw fixing blocks (3) that can move along the linear slide rails (2), and the claw fixing blocks (3) on each linear slide rail are arranged at intervals so that The claw fixing blocks (3) are arranged in a staggered manner, and the claw fixing blocks (3) are fixedly connected with claws (4). After adopting this structure, each finger corresponds to a chute of a slideway, and the chute has a guiding and limiting effect on the finger. When the variable-step-pitch plastic-sealed product finger mechanism moves linearly along the slideway, the finger moves along the chute. As the step distance of the chute gradually increases, the step distance between the claws also increases correspondingly due to the guiding and limiting effect of the chute, so that the plastic-encapsulated products can be smoothly dialed into the material tube, preventing the claws from breaking, and extending the working life. The service life of the finger.

Description

A claw mechanism with variable step distance for plastic-encapsulated products

technical field

The utility model relates to a variable-step-distance plastic-sealed product claw mechanism, in particular to a variable-step-distance plastic-sealed product claw mechanism in an automatic punching and forming system in the semiconductor field.

Background technique

For the plastic-sealed products that need to be installed in tubes, after entering the slideway from the separation mold, the product needs to be dialed into the material tube from the slideway. From the channel to the inlet tube is a process of gradually increasing the step distance. Although the existing equipment used to dial products into the material tube from the slideway also has claws, the distance between the claws cannot be adjusted according to the change in the step distance of the slideway. change, it is easy to cause the finger to break.

Utility model content

The purpose of the utility model is to solve the problem that the distance between the existing claws cannot be changed according to the change of the step distance of the slideway.

The technical scheme adopted by the utility model is: a variable-step-pitch plastic-sealed product claw mechanism, which includes a base plate, two linear slide rails are fixedly connected to the base plate, and several linear slide rails are movably connected to each of the two linear slide rails. The claw fixing blocks that can move along the linear slide rails, the claw fixing blocks on each linear slide rail are arranged at intervals so that the claw fixing blocks on the two linear slide rails are staggered, and the claw fixing blocks are fixed on the There is a claw.

As a further improvement of the utility model, each linear slide rail is provided with four claw fixing blocks.

The beneficial effect adopted by the utility model is: after adopting this structure, each finger corresponds to a chute of a slideway, and the chute has a guiding and limiting effect on the finger. When the variable-step-pitch plastic-sealed product finger mechanism moves linearly along the slideway, the finger moves along the chute. As the step distance of the chute gradually increases, the step distance between the claws also increases correspondingly due to the guiding and limiting effect of the chute, so that the plastic-encapsulated products can be smoothly dialed into the material tube, preventing the claws from breaking, and extending the life of the product. The service life of the finger.

Detailed ways

Below in conjunction with Fig. 1,2,3, the utility model is described further.

As shown in Figures 1, 2, and 3, a claw mechanism for variable step-pitch plastic-sealed products includes a base plate 1, and two linear slide rails 2 are fixedly connected to the base plate 1, and each of the two linear slide rails 2 is There are several claw fixing blocks 3 movable along the linear slide rail 2, and the claw fixing blocks 3 on each linear slide rail are arranged at intervals so that the claw fixing blocks 3 on the two linear slide rails are arranged in a staggered manner. The claw fixing block 3 is fixedly connected with a claw 4, and each linear slide rail is provided with four claw fixing blocks 3.

As shown in Figure 4, before the utility model is used, the substrate 1 is fixed on the linear motion mechanism in the automatic punching forming system, and the position of the finger 4 is adjusted so that the lower end of each finger 4 is located at the corresponding position of the slideway 5. In the chute 6, so that the chute has a guiding and limiting effect on the claw 4, the step distance between each chute 6 at one end of the chute 5 is the original step distance of the plastic packaged product (that is, the step of the product on the lead frame distance), the step distance between each chute 6 at the other end of the slideway 5 is the same as the arrangement step distance of the material pipe.

As shown in Figure 4, when the utility model is in use, the automatic punching and forming system is started, and the linear motion mechanism in the automatic punching and forming system drives the substrate 1 to move and then drives the finger 4 to move along the chute 6. Due to the guiding and limiting effect of the chute 6 and because the claw fixing block 3 can move along the linear slide rail 2, as the step distance of the chute 6 gradually increases, the step distance between the claws 4 also increases accordingly , so that the plastic-encapsulated product can be smoothly dialed into the material tube, preventing the finger from breaking, and prolonging the service life of the finger.
