Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
The technical solutions of some embodiments of the present invention are described below with reference to the accompanying drawings.
Example 1:
as shown in fig. 1 and 2, the present embodiment provides a chip removing device 100, and the chip removing device 100 is used for cooperating with the riveting machine 1 shown in fig. 7 and punching a rivet so that one end of the rivet is punched and pressed against a product. For example, the chip removing device 100 provided by the embodiment may be used in the manufacture of a multi-layer PCB (Printed Circuit Board) Board to realize the connection between the multi-layer PCB boards.
The performance of the chip removing means has a crucial influence on the result of the stamping and on the performance of the product obtained after stamping. For example, as multilayer boards in the PCB industry are developed toward high-level, high-performance and high-security, and especially as the PCB is applied more and more widely in various fields of producing automobiles, communication equipment, medical treatment, aerospace, power supplies and the like, users have made higher demands on the performance of multilayer PCBs. When the multilayer PCB is prepared, lamination is one of essential procedures, and the lamination procedure also has a crucial influence on the quality and the performance of the multilayer PCB. The more common reason for scrap problems in the lamination process is lamination of the inner foreign matter and the inner short circuit. The root of the method is that rivet scraps generated in the pressing process are the primary reasons for foreign matters in the inner layer of the pressing or short circuit of the inner layer. Currently, there is no economical and reliable device or method for effectively solving the problem of micro-short or short circuit of the inner layer of the multi-layer PCB caused by rivet scraps in the related art. It can be seen that it is highly desirable to provide a scrap removal apparatus that avoids the introduction of rivet scrap into the riveted product.
In view of this, the present embodiment provides a scrap removing apparatus 100 capable of preventing rivet scrap from entering a riveted product. The chip removing device 100 includes: a chip removing device body 110 and an air duct structure 120. The chip removing device body 110 is provided with a first ventilation opening 112 and a second ventilation opening 114; the air duct structure 120 is accommodated in the chip removing device body 110 and is provided with an air duct 130; wherein the first ventilation opening 112 and the second ventilation opening 114 are respectively communicated with the air duct 130, so that air flows among the first ventilation opening 112, the air duct 130 and the second ventilation opening 114.
Wherein the chip removing device further comprises a gas driving device 170. The gas-driven device 170 is in communication with the second vent 114 and is adapted to deliver gas to the second vent 114 or to adsorb gas through the second vent 114. For example, the gas driving device 170 is a gas source device capable of generating and delivering gas, or a negative pressure device capable of adsorbing gas to form negative pressure.
As shown in fig. 7, the scrap removing device 100 provided in this embodiment is a part of the riveting machine 10, and the riveting machine 10 further includes a riveting machine body 200. The riveting machine body 200 includes an operation table assembly 210 and a nailing assembly 220 mounted and fixed on the operation table assembly 210. The chip removing device 100 is partially or completely embedded in the operation table assembly 210 and is arranged below the nailing assembly 220. In use, a punch is inserted and fixed into the chip removing device 100. The tacking assembly 220 applies the rivet vertically above the punch such that the punch performs a punch blooming operation on the rivet. During this process, the rivet can generate debris such as metal chips. In order to prevent impurities such as metal debris from entering a riveted product, the chip removing device 100 provided in this embodiment has the first ventilation opening 112 and the second ventilation opening 114 on the chip removing device body 110, and the air duct structure 120 is accommodated inside the chip removing device body 110, and the air duct 130 is disposed on the air duct structure 120. Since the first ventilation opening 112 and the second ventilation opening 114 are respectively communicated with the air duct 130, the air flow can be used for adsorbing or blowing away impurities such as metal debris, thereby preventing the impurities such as the metal debris from entering the riveted product.
Specifically, as shown in fig. 1 and 2, in the chip removing device 100 provided in the present embodiment, the chip removing device 100 has a cylindrical structure. The first ventilation opening 112 is disposed on the top surface of the upper portion of the chip removing device 100, and the second ventilation opening 114 is disposed on the bottom surface or the side wall of the lower portion of the chip removing device 100. In order to make the air flow in the chip removing device 100, an air source or a negative pressure device can be connected with the second ventilation opening 114. When the gas source is connected with the second ventilation opening 114, the gas can be conveyed into the chip removing device 100 through the second ventilation opening 114, and the gas is driven to be discharged through the first ventilation opening 112, so that impurities such as metal chips and the like can be blown away. When a negative pressure device is connected to the second vent 114, air around the first vent 112 can be driven to drive impurities such as metal chips to enter the chip removing device 100 together and be discharged from the second vent 114, so as to adsorb and discharge the impurities such as metal chips.
The first ventilation opening 112 has a circular arc structure, a semicircular ring structure or a circular ring structure arranged around the periphery of the top surface of the upper portion of the chip removing device 100. The number of the first ventilation openings 112 may be plural. For example, as shown in fig. 1, the first ventilation opening 112 has a circular grid structure. The design of the grid structure can ensure smooth circulation of air, and can form a large negative pressure at the periphery of the first vent 112 when the air flow is used for adsorbing impurities such as metal chips, so as to quickly and effectively adsorb the impurities such as the metal chips.
In order to facilitate the installation and placement of the air duct structure 120, the dust removing device body 110 may be a detachable and separable structure. For example, as shown in fig. 1, the chip removing device body 110 includes a base 116 and a cover 118 which are disposed up and down and detachably connected by screws. The air duct structure 120 is accommodated in a space formed by the base 116 and the cover 118.
In order to improve the efficiency of the airflow, and thus improve the effect of adsorbing or blowing away impurities such as metal debris, the air duct 130 is disposed on the air duct structure 120. The air duct 130 is a plurality of gully structures and/or groove structures formed on the inside or surface of the air duct structure 120. A plurality of the gully structures and/or groove structures are in communication with one another such that airflow flows between the gully structures and/or groove structures to create a greater air pressure around the first vent 112.
In summary, in the present embodiment, through the mutual cooperation of the first ventilation opening 112, the air duct 130 and the second ventilation opening 114, rivet scraps can be effectively removed, and the rivet scraps, copper scraps and other impurities are prevented from falling onto the inner core board of the product to be riveted. In addition, this embodiment need not implement artifical clean in the riveting process, has solved artifical clean inefficiency, with high costs, easy clean not in place to the rivet bits appear anti-sticking board face phenomenon scheduling problem easily, has improved the quality of riveting product from this, especially has improved the security and the reliability of riveting product, can effectively avoid it to appear the short circuit.

Specifically, the base 116 has a truncated cone-shaped configuration, and the cover 118 includes an upper top wall and an annular side wall extending vertically downward around the upper top wall. During installation, the cover 118 covers the base 116 from top to bottom, and fasteners such as screws sequentially penetrate through the side wall of the cover 118 and the side wall of the base 116, so that the base 116 and the cover 118 are connected. The outer peripheral dimension of the air duct structure 120 and the inner cavity 140 are adapted to each other, so that a gap is formed between the air duct structure 120 and the base 116, and the gap is configured to enable an air flow to flow along the gap, thereby increasing the air pressure inside the chip removing device 100, and further increasing and improving the chip removing effect. In addition, the height of the air duct structure 120 and the height of the inner cavity 140 are adapted to each other, so that a gap is formed between the air duct structure 120 and the cover 118. The provision of this gap ensures that the air flow is drawn in or out of the cover 118 in large quantities and quickly, thereby achieving a further increase and improvement in the effectiveness of the chip removal.
