[0032] To help those skilled in the art better understand the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments. Obviously, the embodiments described are only a portion of the present invention, not all of the embodiments. All other embodiments derived by those skilled in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0033] The core of this utility model is to provide a new type of track cover, a structural diagram of a specific implementation method is shown in FIG. Figure 3 As shown, it is called the specific embodiment 1, which includes a plate-shaped body 10, an air channel 20 in the cover plate, an air inlet 30 of the cover plate and an air outlet 40 of the cover plate;

[0034] The cover plate inner air passage 20 passes through the plate-shaped body 10 and forms the cover plate air outlet 40 and the cover plate air inlet 30 on the surface of the plate-shaped body 10;

[0035] The output air flow from the external air source passes through the cover plate air inlet 30 and the cover plate inner air channel 20 in sequence, is discharged from the cover plate air outlet 40 , and forms an air curtain in the area in front of the cover plate air outlet 40 .

[0036] The novel track cover plate can be a solid cover plate, in which case the air passage 20 in the cover plate is a channel drilled in the solid cover plate. The novel track cover plate can also be a hollow cover plate, in which case the air passage 20 in the cover plate is a cavity in the hollow cover plate, or a pipe laid separately in the cavity.

[0037] Of course, the number of the cover plate air inlet 30 and the cover plate air outlet 40 is not limited in this utility model, but usually the cover plate air inlet 30 is unique, and the cover plate air outlet 40 is multiple, and the multiple cover plate air outlets 40 are arranged at different positions. In this utility model, it is assumed that the carrier tape a is transported in the horizontal direction, and the cover tape b is first transported vertically from the top to the bottom, and then turns to the same direction as the carrier tape a at the corresponding position of the braided cover plate packaging end to package the electronic components in the carrier tape a. Figure 1 and Figure 2 ,in Figure 1 It is a partial three-dimensional schematic diagram of the packaging position of the cover tape b and the carrier tape a of the taping machine. Figure 2 for Figure 1 A cross-sectional schematic diagram of the invention is shown. In the figure, 01 represents the packaging end of the braided cover tape B (framed by an elliptical dotted line). In the following figures, 02 represents the recessed carrier tape viewing hole, and 100 represents the novel track cover. Of course, in actual production, the relative positions of the various components may be adjusted based on actual conditions.

[0038] In the present invention, an air curtain is formed in front of the cover plate air outlet 40, so the cover plate air outlet 40 should be set on one side of the open window of the braiding machine, and the air curtain covers the top of the open window to prevent foreign matter c from falling into the open window.

[0039] As a specific embodiment, the plate-like body 10 includes a concave carrier a observation hole;

[0040] The cover plate air outlet 40 is disposed on the side wall of the concave carrier tape a observation hole, and the air curtain of the cover plate air outlet 40 covers the concave carrier tape a observation hole.

[0041] On the transport track of carrier a, in order to monitor the working condition of carrier a, it is necessary to open an observation hole for carrier a to monitor whether the status of carrier a passing through the observation hole for carrier a is normal. At the same time, this specific embodiment further improves the observation hole for carrier a to a concave observation hole for carrier a. The concave observation hole for carrier a refers to the observation hole for carrier a being arranged in the concave part of the new track cover, and the observation hole for carrier a is arranged at the bottom of the concave part. The advantage of this is that the observation hole for carrier a is closer to the carrier a. If an abnormality is found in carrier a, the problematic carrier a can be directly intervened and adjusted through the concave observation hole for carrier a.

[0042] Furthermore, the cover plate air outlet 40 is a strip-shaped air outlet. The strip-shaped air outlet is more likely to form a planar airflow in the front area, that is, to form an air curtain with better coverage effect, such as Figure 3 and Figure 4 As shown in Figure 3 for Figure 4 The top view shows that the observation hole of the recessed carrier a in the figure is a strip-shaped air outlet arranged on the side of the recess at the bottom of the circular recess. It is not difficult to see from the figure that the air curtain formed by the strip-shaped air outlet covers the observation hole of the recessed carrier a, which can achieve a better covering effect and further reduce the possibility of foreign matter c falling into it.

[0043] As a specific embodiment, the cover plate air outlet 40 is provided at the packaging end of the braided cover tape b of the track cover plate;

[0044] The cover plate air outlet 40 is arranged toward the cover tape b.

[0045] Please refer to further Figure 1 and Figure 2 ,exist Figure 2 It is also shown in the figure that the packaging end of the braided cover plate is one end of the conveyor belt of the track cover plate close to the cover tape b. Below the braided cover plate packaging end, the carrier tape a is combined with the cover tape b to encapsulate the electronic components. In order to facilitate timely detection and adjustment when a fault occurs, an opening is usually set.

[0046] The cover plate air outlet 40 can be set horizontally or obliquely upward. The air flow ejected from the cover plate air outlet 40 impacts the cover tape b conveyed vertically downward, forming an air curtain above the opening corresponding to the packaging end of the braided cover tape b, preventing foreign matter c from falling in.

[0047] Preferably, the air outlet direction of the cover plate air outlet 40 is inclined upward and coincides with the feeding direction of the cover tape b.

[0048] After a lot of theoretical calculations and practical tests, it was found that spraying air in an inclined upward direction can better prevent foreign objects from falling.

[0049] The plate-like body 10 is a non-magnetic stainless steel plate-like body 10. During the operation of some braiding machines, magnetic force is required to achieve the assembly of the carrier tape a and the cover tape b. Therefore, other components in the braiding machine, such as the plate-like body 10 of the new track cover provided by the present invention, are preferably non-magnetic plate-like bodies 10. Furthermore, stainless steel is selected to make the plate-like body 10. Stainless steel is non-magnetic, has high mechanical strength, mature processing technology and low cost. Of course, other types of plate-like bodies 10 can also be selected according to actual conditions, and the present invention does not limit this.

[0050] As a preferred embodiment, the new track cover includes a plurality of cover air outlets 40. Figure 4 As shown, the new track cover can be simultaneously arranged on the side wall of the concave carrier tape a observation hole and the packaging end of the braided cover tape b of the track cover. Of course, it can also be installed in different areas of the cover body that require openings according to actual needs, so that the corresponding air curtain covers the top of the opening, thereby greatly improving the versatility of the new track cover provided by the utility model.

[0051] On the basis of the specific embodiment 1, the cover plate air inlet 30 is further improved to obtain the specific embodiment 2, and its corresponding structural diagram is as follows: Figures 5 to 7 As shown, it includes a plate-shaped body 10, an air channel 20 in the cover plate, an air inlet 30 in the cover plate, and an air outlet 40 in the cover plate;

[0052] The cover plate inner air passage 20 passes through the plate-shaped body 10 and forms the cover plate air outlet 40 and the cover plate air inlet 30 on the surface of the plate-shaped body 10;

[0053] The output air flow from the external air source passes through the cover plate air inlet 30 and the cover plate inner air channel 20 in sequence, is discharged from the cover plate air outlet 40 , and forms an air curtain in the area in front of the cover plate air outlet 40 .

[0054] The novel track cover plate can be a solid cover plate, and the air passage 20 in the cover plate is a channel drilled in the solid cover plate. The novel track cover plate can also be a hollow cover plate, and the air passage 20 in the cover plate is a cavity in the hollow cover plate, or a pipe laid separately in the cavity.

[0055] The cover plate air inlet 30 is a periscope air inlet provided on the plate-shaped body 10 .

[0056] The difference between this embodiment and the above embodiment is that the cover plate air inlet 30 in this embodiment is limited to a special type, and the remaining steps are the same as those in the above embodiment, which will not be described in detail here.

[0057] Please refer to Figure 5 、 Figure 6 and Figure 7 The three figures are respectively a top view, a front view, and a cross-sectional view of this embodiment. The periscope-style air inlet is a curved air intake duct that extends higher than the cover body, resembling a submarine periscope. Designating the cover air inlet 30 as a periscope greatly facilitates the connection and installation of the external air source to the novel track cover, while also reducing the design difficulty of the internal airway structure of the plate-like body 10 and improving design and production efficiency.

[0058] The utility model also provides a tape braiding machine, a partial structural diagram of a specific embodiment of the invention is shown in FIG. Figure 1 and Figure 2 As shown, it is called the specific embodiment three, the braiding machine includes an air pump and a new type of track cover as described in any one of the above;

[0059] The air outlet of the air pump is connected to the cover air inlet 30 of the novel track cover.

[0060] The braiding machine provided in this specific embodiment is in contrast to the new track cover mentioned above. Therefore, the structure of the braiding machine in this specific embodiment can refer to the new track cover mentioned above, and will not be elaborated here.

[0061] Preferably, the air pump is an air compression pump. The air compression pump does not require an external air tank, which reduces the cost and improves the usability while reducing the size of the device. Of course, other types of air pumps can also be used, and the present invention is not limited here.

[0062] The present invention provides a taping machine, which includes an air pump and a new type of track cover as described above; the air outlet of the air pump is connected to the cover air inlet 30 of the new type of track cover. Optionally, in the taping machine, the air pump is an air compression pump. In the present invention, an air duct (i.e., the air duct 20 inside the cover) is built into the track cover, so that gas from an external air source can reach the area to be shielded along the air duct 20 inside the cover, and be ejected from the cover air outlet 40 to form an air curtain, thereby protecting the area covered by the air curtain and preventing foreign matter c from entering the taping machine below the air curtain and causing contamination, thereby greatly improving the working stability of the taping machine and the final packaging yield of electronic components.
