[0039] Figure 1 Fig. 1 is a structural schematic diagram of the cleaning component of the embodiment.
[0040] In some embodiments, as shown in Fig. 1, the cleaning component of the embodiment comprises a heat-conducting part and a connecting part 6 arranged on the heat-conducting part. Figure 1 The connecting part 6 is used to connect with a heating device. The heating device comprises a handheld part, and the handheld part comprises a heating head. When the cleaning component is mounted on the handheld part, for example, a threaded hole is formed on the connecting part 6, so that the heating head is screwed into the threaded hole to form an electric soldering iron. The operator drives the cleaning component to move above or beside the functional device A1 through the handheld part, and the heat-conducting part can conduct the heat generated by the heating head to the electronic device A to be processed through the connecting part 6.
[0041] Optionally, the material of the heat-conducting part comprises, but is not limited to, copper alloy or iron alloy, so that the heat-conducting part has good heat-conducting performance and has a certain hardness.
[0042] Figure 2 Fig. 2 is a structural schematic diagram of the heat-conducting part of the embodiment. Figure 3 Fig. 3 is a sectional view of A-A in Fig. 2. Figure 4 Fig. 4 is a sectional view of B-B in Fig. 2. Figure 3 Fig. 5 is a sectional view of C-C in Fig. 2. Figures 2-4 Fig. 6 is a profile of the scraper 1 in Fig. 2.
[0043] In some embodiments, as shown in Fig. 1, the heat-conducting part of the embodiment comprises an extension handle 2 and a scraper 1. The scraper 1 has a first scraping edge 31. The first scraping edge 31 is arranged obliquely and located on the side of the scraper 1 away from the extension handle 2. In the extension direction of the first scraping edge 31, the scraper 1 comprises an oblique head 11 and a main body 12, and the main body 12 is connected with the end of the extension handle 2. In the axial sectional direction of the extension handle 2, the oblique head 11 is arranged staggered with the extension handle 2. That is, the oblique head 11 is arranged obliquely to the side of the extension handle 2 and extends to the side of the extension handle 2. Figures 2-4
[0044] Figure 5 is a schematic diagram of the working state of the cleaning component in some embodiments of the present embodiment. The electronic device A in the figure can be a multi-layer circuit board or a circuit assembly made by system-in-package. Taking the multi-layer circuit board as an example, the functional device A1 is arranged on the circuit board A2, and the functional device A1 includes but is not limited to a capacitor or a resistor. The functional device A1 is encapsulated by a packaging material, which can be a cresol formaldehyde epoxy resin (such as Figure 5 The packaging material covers the functional device A1 from above and from the side. Meanwhile, a copper layer is arranged on the outer surface of the packaging material.
[0045] Further referring to Figure 5 , in the use of the cleaning component, the copper layer on the side is cleaned first. The scraper 1 is pressed against the position on the packaging material corresponding to the functional device A1, so that the scraper 1 can heat the packaging material. The heating temperature of the heating head can be configured to 300 degrees, and the cresol formaldehyde epoxy resin will deform at 210 degrees. At this time, horizontally moving the first scraping edge 31 (for example, moving along a direction perpendicular to the first scraping edge 31) can effectively peel the packaging material from the circuit board A2, so that the functional device A1 is exposed.
[0046] In summary, in the cleaning component of the present embodiment, the scraper 1 is arranged on the extension handle 2, and the contact area between the scraper 1 and the packaging material is increased by using the inclined blade head 11 and the main body 12. Thus, the heat conduction efficiency is improved, and the packaging material is more easily deformed by heat. In addition, the length of the first scraping edge 31 is also increased, further improving the cleaning speed of the packaging material. On the other hand, the inclined blade head 11 protrudes laterally to the extension handle 2, which is more convenient for the operator to observe the cleaning area when moving the cleaning component by the hand-held part. At the same time, the holding angle of the operator is also improved, and the operator is not easy to feel tired after a long time of operation.
[0047] In some embodiments, as shown in Figure 3 , the scraper 1 has a contact surface 4, the contact surface 4 extends from the inclined blade head 11 to the main body 12, and the edge of the contact surface 4 forms the first scraping edge 31. The contact surface 4 in the present embodiment can be used to heat the packaging material to increase the contact area between the scraper 1 and the packaging material. Meanwhile, the operator can tilt the scraper 1 and drag the first scraping edge 31 on the packaging material, so that the first scraping edge 31 can directly clean the packaging material. The heating and scraping steps are simplified.
[0048] In some embodiments, as shown in Figures 3-4 , the contact surface 4 includes a first contact surface 41 and a second contact surface 42, the first contact surface 41 is away from the extension handle 2, and the first contact surface 41 is connected with the second contact surface 42 and forms the first scraping edge 31.
[0049] In particular, the first contact surface 41 is not coplanar with the second contact surface 42. The central axis of the extension handle 2 passes through the first contact surface 41. The second contact surface 42 is arranged obliquely relative to the first contact surface 41 and faces the oblique direction of the first contact surface 41.
[0050] The operator can heat the packaging material by using the first contact surface 41 or the second contact surface 42 to facilitate the operator's observation of the cleaning area. For example, the operator first heats the packaging material by using the first contact surface 41, and then tilts the hand-held portion, and when the operator scrapes the packaging material by using the first scraping blade 31, the second contact surface 42 faces the packaging material. In this form, the second contact surface 42 can also heat the packaging material contacted at any time.
[0051] Figure 6 is a schematic diagram of the working state of the cleaning member of the embodiment in other embodiments.
[0052] In some embodiments, as shown in Figure 2 , the oblique tool head 11 has a relief inclined surface 43. Further referring to Figure 3 , the relief inclined surface 43 is away from the first contact surface 41, and one side of the relief inclined surface 43 is connected to the extension handle 2, and the other side is obliquely connected to the lateral side of the extension handle 2 and connected to the first contact surface 41 to form the second scraping blade 32.
[0053] In an optional implementation, as shown in Figure 5 , the packaging material above the functional device A1 is first cleaned by using the first scraping blade 31. Further referring to Figure 6 , the packaging material is cleaned again by using the second scraping blade 32. In this form, the narrow area between the two functional devices A1 can be cleaned to avoid the contact between the scraper 1 and the functional device A1. So that the operator can replace the specific functional device A1.
[0054] In some embodiments, as shown in Figure 3 , the second scraping blade 32 is connected to the first scraping blade 31 to form a tip 5. The tip 5 is located in the oblique tool head 11. When the first scraping blade 31 or the second scraping blade 32 is difficult to clean the packaging material, the operator can tilt the hand-held portion so that the tip 5 faces the packaging material, thereby increasing the pressure generated by the scraper 1 on the packaging material, which helps the packaging material to fall off.
[0055] In some embodiments, as shown in Figure 3 , one side of the second contact surface 42 is connected to the relief inclined surface 43 to form a first edge 44, one end of the first edge 44 is connected to the second scraping blade 32 and the first scraping blade 31 to form the tip 5, and the other end of the first edge 44 is obliquely connected to the extension handle 2.
[0056] The tip 5 in the embodiment is composed of the first scraping blade 31, the second scraping blade 32 and the first edge 44, so that the tip 5 can extend into a relatively narrow area to remove the packaging material. The functional device A1 is avoided from being bumped. Meanwhile, the pin of the functional device A1 or the pad of the circuit board A2 can be heated by the tip 5 and the second scraping blade 32, so that the functional device A1 can be removed from the circuit board A2.
[0057] In some embodiments, as shown in Figures 3-4 , the number of the second contact surfaces 42 is two and they are symmetrically arranged on both sides of the first contact surface 41, and the two second contact surfaces 42 form two first scraping blades 31 with the first contact surface 41. Specifically, the number of the tip 5 in the above embodiment is also two. Thus, by the two first scraping blades 31, the scraper 1 can remove the packaging material in two directions, improving the removal efficiency of the operator.
[0058] In some embodiments, as shown in Figure 2 and Figure 3 , the first contact surface 41 is a rectangular plane and is inclined to the lateral direction of the extension handle 2 by 35 degrees to 55 degrees (as shown by angle a1 in Figure 2 ).
[0059] Preferably, the angle a1 is configured to be 45 degrees. Thus, the removal component can better meet the ergonomics, and the operator can hold the handheld part in a pen-holding posture, so that it is more labor-saving to drag the scraper 1.
[0060] In some embodiments, as shown in Figure 2 and Figure 3 , the avoidance inclined surface 43 and the first contact surface 41 are both planes and the included angle is 20 degrees to 35 degrees (as shown by angle a2 in Figure 2 ).
[0061] Preferably, the angle a2 is 24 degrees. Thus, the second scraping blade 32 is more sharp, improving the removal speed of the packaging material. Meanwhile, it can also ensure that the inclined cutter head 11 has sufficient mechanical strength to avoid breaking of the inclined cutter head 11.
[0062] In some embodiments, as shown in Figure 4 , the first contact surface 41 and the second contact surface 42 are both planes and the included angle is 100 degrees to 150 degrees (as shown by angle a3 in Figure 4 ).
[0063] Preferably, the angle a3 is 130 degrees. Thus, it can ensure that the first scraping blade 31 has sufficient structural strength to avoid deformation of the first scraping blade 31 in use.
[0064] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
