Description

Technical Field

[0001] The utility model belongs to the field of mechanical technology and relates to a waste material suction device, in particular to a negative pressure stamping micro waste material collection device and electronic product stamping equipment. Background Art

[0002] In the current electronic product manufacturing industry, especially in the production process of notebook shells, stamping technology is a common and important processing method. This technology uses a mold to stamp metal sheets into a specified shape, including the processing of parts such as speaker meshes; however, there is a major problem in this process, that is, a large amount of tiny waste will be generated during the stamping process. Usually, the size of these wastes is very small, such as 0.8*0.6mm. If these tiny stamping wastes are not collected and processed in a timely and effective manner, it will lead to many problems:

[0003] First, if tiny scraps are left on the production line, they may get stuck in the stamping die, which will not only affect the quality of the product and cause the product to be scrapped due to surface unevenness or other defects, but more seriously, it may directly damage the expensive stamping die. Damage to the stamping die will not only cause production suspension, but also increase the cost of repairing or replacing the die for the company;

[0004] Secondly, although traditional industrial dust collection equipment can solve the problem of stamping waste collection, these equipment are usually expensive and take up a large space. This is a big challenge for manufacturers with limited facility space or limited budget; in addition, these dust collection equipment are usually less mobile and flexible, and are not easy to adjust and move according to the actual needs of the production line.

[0005] The patent with application number CN202222683596.2 discloses a waste recovery device for powder metal parts processing, and its technical solution includes: a mounting frame, a mounting box and a fan, a mounting box is fixedly mounted on the top of the mounting frame, a docking sleeve is fixedly connected to one side of the mounting box, a dust head is fixedly connected to one end of the docking sleeve, a linkage rod is movably mounted on the bottom of the dust head, a movable plate is fixedly connected to one side of the mounting frame, and a docking tube is fixedly mounted on the bottom of the mounting box. By providing the fan, the mounting box, the dust head and the collection bag, it is relatively convenient to form negative pressure inside the mounting box through the rotation of the fan, so that the inside of the mounting box can generate strong suction, the metal powder can be absorbed by the dust head, the metal powder can be isolated by the filter, and the metal powder can be conveniently absorbed by the collection bag, making it more convenient to use.

[0006] The waste recovery device for powder metal parts processing collects the waste of powder metal parts through fans and filters, and relies on the suction of the fan to guide the waste to the collection bag. It is mainly suitable for larger waste of powder metal parts, and the processing effect is not ideal for tiny waste.

[0007] Therefore, it is particularly important to develop a new type of stamping waste collection device that can effectively collect tiny stamping waste and solve the problems of high cost and large footprint of existing equipment. Utility Model Content

[0029] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0030] Embodiment 1

[0031] like Figures 1 to 3 As shown, the negative pressure stamping micro waste collection device comprises a box shell 1 with a closed inner cavity, the closed inner cavity comprises a collection cavity located on the left and a negative pressure cavity located on the right, the collection cavity is connected with the negative pressure cavity through a bending channel in the middle, a collection bag 5 is arranged in the collection cavity, the bag mouth of the collection bag 5 is connected to the collection passage assembly, the negative pressure cavity is connected to the suction passage assembly, and an interception net 7 is arranged on the inner port of the suction passage assembly connected to the negative pressure cavity.

[0032] The collection passage assembly includes a collection pipe 2 and a pipe fixing block 3. A through port 1 is provided on the top surface of the box shell 1 to communicate with the collection chamber. A threaded hole 1 is provided on the pipe fixing block 3. The pipe fixing block 3 is fixed to the top surface of the box shell 1 by a plurality of screws, so that the threaded hole 1 is connected with the through port 1, and the threaded pipe section of the collection pipe 2 extends into the threaded hole 1 to form a threaded engagement connection. The pipe fixing block 3 fixes the collection pipe 2 on the box shell 1 and keeps the collection pipe 2 in sealed communication with the collection chamber.

[0033] like Figure 2 and 3 As shown, the outer periphery of the bag opening of the collection bag 5 is sleeved with the sealing disk 4, and the sealing disk 4 is fixed to the inner side wall of the through hole 1 by a plurality of screws, so that the bag opening of the collection bag 5 is sealed and connected to the through hole 1, and the ventilation mesh holes are evenly distributed on the collection bag 5. The sealing disk 4 realizes the fastening, convenience and rapid installation of the collection bag 5, so that all the tiny waste materials can smoothly enter the collection bag 5.

[0034] The first end of the collecting pipe 2 is connected to the waste collecting station of the mold, and is used for timely suction and removal of tiny waste generated by stamping.

[0035] like Figure 2 and 3 As shown, a plurality of baffles 6 are vertically arranged in the middle of the closed inner cavity, and a flow gap is arranged between the baffle 6 and the top wall or the bottom wall of the box shell 1, and a baffle channel is formed between adjacent baffles 6, and the flow gap at the bottom and the flow gap at the top are arranged alternately, and the flow gap at the bottom, the baffle channel and the flow gap at the top form a bending channel. A reciprocating bending channel is formed by a plurality of baffles 6 arranged in parallel, so that the airflow can enter the negative pressure cavity from the collection cavity through the bending channel, which increases the difficulty of tiny waste entering the negative pressure cavity, thereby preventing tiny waste from entering the suction path.
