Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape processing, in particular to a small-sized carrier tape processing device. Background Art

[0002] A carrier tape is a strip-shaped product widely used in the field of electronic packaging. It has a specific thickness, and holes for placing electronic components and positioning holes for indexing are equidistantly distributed in the length direction. The main function of this carrier tape is to cooperate with a cover tape (upper sealing tape) to carry and store electronic components such as resistors, capacitors, transistors, and diodes in the pockets of the carrier tape. Among them, the forming and punching of the carrier tape are important steps in the production and processing of the carrier tape.

[0003] When traditional carrier tapes are processed, the forming and punching of the carrier tape are operated separately, that is, the heated carrier tape is moved to the forming position, and after forming, it continues to move to the punching position for punching. This results in a reduction in production efficiency, and the uncompletely cooled carrier tape is not only prone to deformation when pulled to the punching position, but also leads to a reduction in punching accuracy. Therefore, we propose a small-sized carrier tape processing device to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings in the prior art that the forming and punching steps are operated separately during the processing of carrier tapes, resulting in a reduction in production efficiency and the uncompletely cooled carrier tape being prone to reducing the punching accuracy, and to propose a small-sized carrier tape processing device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A small-sized carrier tape processing device includes a bracket. Limiting grooves are symmetrically arranged on both sides of the bracket, and the same carrier tape is slidably connected inside the two limiting grooves. A fixed plate is fixedly arranged inside the bracket, and a first cylinder is fixedly arranged on the inner wall of the top of the bracket. The output end of the first cylinder is fixedly connected with a moving plate, and the moving plate is located inside the bracket and is slidably connected with the bracket.

[0007] The device further includes:

[0008] An extrusion assembly, which is arranged on the fixed plate and the moving plate and is used for extruding the carrier tape to form holes for placing electronic components;

[0009] A punching assembly, which is arranged inside the bracket and is used for punching during the extrusion forming process;

[0010] A cooling assembly, which is arranged on the fixed plate and is used for cooling the carrier tape during punching and cooperating with the punching assembly to complete punching.

[0011] In a possible design, the extrusion assembly includes a fixed mold and a movable mold. The fixed mold is fixedly arranged on the top of the fixed plate, and the movable mold is fixedly arranged on the bottom of the movable plate. A chute corresponding to the carrier tape is formed at the top of the fixed mold, and a plurality of mold cavities are arranged at equal intervals inside the chute. A plurality of mold cores are arranged at equal levels at the bottom of the movable mold, and the plurality of mold cores are matched with the mold cavities.

[0012] In a possible design, a first air passage is formed at the bottom of the movable plate, and air outlet holes are formed in each of the plurality of mold cores. The plurality of air outlet holes are communicated with the first air passage. By introducing high-pressure gas into the air outlet holes, the mold cores are inflated with the high-pressure gas to accelerate the extrusion molding process.

[0013] In a possible design, the punching assembly includes two second cylinders. The output ends of the two second cylinders are fixedly connected to the same punching plate. The punching plate is located inside the bracket and is slidably connected to the bracket. The punching plate is located above the movable plate. The first cylinder penetrates through the punching plate and is slidably connected to the punching plate. A plurality of punching heads are fixedly arranged at the bottom of the punching plate. The plurality of punching heads are symmetrically arranged in two rows. First openings and second openings corresponding to the plurality of punching heads in two rows are symmetrically formed on the fixed plate and the movable plate respectively. The plurality of punching heads are inserted into the corresponding first openings and second openings.

[0014] In a possible design, a first through hole and a second through hole corresponding to the plurality of punching heads are respectively formed on the fixed mold and the movable mold. The plurality of punching heads are respectively inserted into the corresponding first through hole and second through hole.

[0015] In a possible design, the cooling assembly includes a first groove formed at the top of the fixed plate. Water inlets and water outlets are respectively arranged on both sides of the fixed plate. The water inlets and water outlets are both communicated with the first groove. By circulating cold water into the first groove, the fixed mold thereon is cooled to accelerate the cooling of the carrier tape during the extrusion molding process for punching.

[0016] In this application, first, the heated carrier tape slides to a predetermined position through the limiting groove. Subsequently, the first cylinder drives the movable plate to move downward, driving the movable mold to approach the fixed mold. The mold cores at the bottom of the movable mold are embedded into the corresponding fixed mold to extrude the carrier tape, causing the carrier tape to deform to form the required holes. At the same time, high-pressure gas is introduced into the air outlet holes of the mold cores through the first air passage, so that the carrier tape quickly deforms under the action of the air pressure and fits against the inner wall of the mold cores to accelerate the extrusion molding process.

[0017] After the extrusion molding is completed, the first cylinder drives the moving plate to remain in place, continuously fixing the position of the carrier tape. At this time, the two second cylinders work simultaneously to push the punching plate downward. The punch at the bottom of the punching plate passes through the first opening and the second opening on the fixed plate and the moving plate, as well as the first through hole and the second through hole on the fixed mold and the moving mold, to precisely punch the carrier tape.

[0018] Before the punching process, the cooling component starts to work, circulating and injecting cold water through the first groove at the top of the fixed plate to cool down the fixed mold. The circulating flow of the cold water effectively reduces the mold temperature, accelerates the cooling speed of the carrier tape, creates favorable conditions for the subsequent punching operation. At the same time, the cooling process also helps to improve the forming quality and dimensional stability of the extrusion molding.

[0019] Beneficial effects:

[0020] In the present utility model, the small carrier tape processing equipment continuously performs the forming and punching processes on the same equipment, reducing the transfer time between processes and greatly improving the overall production efficiency.

[0021] In the present utility model, the small carrier tape processing equipment ensures the accuracy of forming through the assisted forming with the introduced high-pressure gas. At the same time, the punching component does not need to be repositioned, ensuring the accurate punching position.

[0022] In the present utility model, the small carrier tape processing equipment has a cooling component that circulates and injects cold water to quickly reduce the mold temperature, accelerating the cooling process after the carrier tape is formed, providing good conditions for the subsequent punching operation, and also improving the forming quality of the product.

[0023] In the present utility model, by continuously performing the forming and punching processes on the same equipment, the transfer time between processes is reduced, and the overall production efficiency is improved. The assisted forming with the introduced high-pressure gas ensures the accuracy of forming. At the same time, the punching component does not need to be repositioned, ensuring the accurate punching position.
