Description

Technical Field

[0001] The utility model relates to the technical field of sandblasting equipment, in particular to a sandblasting jig. Background Art

[0002] Currently, sandblasting is the primary surface treatment for heat sink materials. Specifically, compressed air is used as a power source to spray high-speed sand particles onto the material surface, achieving a uniform surface treatment without affecting the part's dimensions. This removes burrs and oxides from the material surface, further purifies the surface, and creates a surface with a suitable roughness.

[0003] However, since the heat sink material used as the integrated circuit packaging substrate is often small in size and complex in shape, the heat sink material is often sandblasted by clamping during the sandblasting process. However, only a single heat sink material can be sandblasted each time, resulting in reduced overall production efficiency and increased production costs.

[0004] Therefore, the above problems need to be solved urgently. Utility Model Content

[0029] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0030] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0031] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0032] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0033] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0034] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0035] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0036] In this embodiment, a sandblasting jig is proposed to improve the sandblasting quality and efficiency of heat sink materials. Of course, in some other feasible embodiments, the sandblasting jig can also be used to sandblast other products to be sandblasted.

[0037] Specifically, see Figures 1 to 3 The sandblasting jig includes a first shell 1 and a second shell 2. The first shell 1 can be detachably mounted on the second shell 2, and the first shell 1 and the second shell 2 can be assembled to form a receiving cavity for accommodating multiple heat sink materials 100; an opening 11 is provided on the first shell 1, which is connected to the receiving cavity and is used to connect the sandblasting gun head 200.

[0038] It can be understood that by placing multiple heat sink materials 100 in the receiving groove formed by the first shell 1 and the second shell 2, multiple heat sink materials 100 can be sandblasted in a relatively closed space, which not only avoids the loss of heat sink materials 100 during the sandblasting process, but also improves the sandblasting efficiency. After the sandblasting is completed, the first shell 1 and the second shell 2 are separated to facilitate the removal of the heat sink material 100, thereby facilitating the subsequent sandblasting of the heat sink material 100.

[0039] Furthermore, the sandblasting port of the sandblasting gun head 200 is located in the accommodating chamber, and a sleeve is provided between the sandblasting gun head 200 and the opening 11 so as to enable relative rotation between the first shell 1 and the sandblasting gun head 200. It is understandable that during the sandblasting process, the sandblasting gun head 200 and the sandblasting jig can rotate relative to each other, so that the sandblasting heat sink material 100 with sandblasting can be sandblasted in all aspects, thereby improving the sandblasting quality, that is, one of the sandblasting gun head 200 and the sandblasting jig can rotate, or both can rotate, and there is a speed difference during the rotation process. In addition, the sandblasting port is located in the accommodating chamber, which enables the sandblasting gun head 200 to spray all the sandblasting materials into the accommodating chamber during the sandblasting process, thereby avoiding waste of sandblasting materials. The sandblasting material is preferably quartz sand or the like.

[0040] For example, during the sandblasting process, the sandblasting jig can rotate with the sandblasting gun head 200 as the rotation center, thereby driving the heat sink material 100 to move. During the movement of the heat sink material 100, each surface of the heat sink material 100 can be sandblasted, thereby improving the sandblasting quality.

[0041] Preferably, the first shell 1 and the second shell 2 are both cylindrical. This arrangement can prevent the corners of the entire sandblasting jig from colliding with the external environment, thereby improving safety performance.

[0042] In this embodiment, the first housing 1 has a first receiving groove 12, and the second housing 2 has a second receiving groove 21. The notch of the first receiving groove 12 and the notch of the second receiving groove 21 are aligned, and the shapes and dimensions of the two are identical. This arrangement ensures a smooth transition between the walls of the first receiving groove 12 and the second receiving groove 21, thus ensuring that there are no dead angles within the receiving grooves and guaranteeing the quality of the sandblasting of each heat sink material 100.

[0043] Preferably, both the first shell 1 and the second shell 2 are made of plastic material. It is understood that plastic material is flexible and wear-resistant, thereby preventing surface damage caused by collision between the walls of the first accommodating groove 12 and the walls of the second accommodating groove 21 during movement of the heat sink material 100, thereby improving sandblasting quality.

[0044] Furthermore, the first housing 1 has a first flange 13 facing away from the first receiving groove 12, and the second housing 2 has a second flange 22 facing away from the second receiving groove 21. The first flange 13 is connected to the second flange 22 via the connector 3. It will be appreciated that the first flange 13 and the second flange 22 provide a mounting position for the connector 3, thereby further avoiding dead angles in the receiving cavity and facilitating installation of the connector 3.

[0045] Preferably, the connecting member 3 includes a plurality of bolts, and the plurality of bolts are evenly distributed on the first flange 13. It is understandable that the first shell 1 and the second shell 2 are detachable by the bolts. Since the first shell 1 and the second shell 2 are preferably made of rubber material, the bolt connection method can improve better stability and vibration resistance during the entire rotation process of the sandblasting jig compared to the direct threaded connection method between the first shell 1 and the second shell 2, thereby further improving safety performance.

[0046] Exemplarily, there are preferably four bolts, which are evenly distributed on the first flange 13 and can be screwed to the second flange 22, thereby ensuring that the first flange 13 and the second flange 22 fit tightly together, so that the first shell 1 and the second shell 2 can be assembled into a relatively closed sandblasting environment, thereby further improving the safety performance of the sandblasting fixture.

[0047] In this embodiment, hollow holes 4 are uniformly distributed on the first shell 1 and the second shell 2. The size of the hollow holes 4 is smaller than the size of the heat sink material 100. It is understood that during the sandblasting process, the sandblasting material can leave the accommodating cavity through the hollow holes 4, thereby preventing the sandblasting material from accumulating in the accommodating cavity and affecting the sandblasting quality.

[0048] Furthermore, as a consumable material, the sandblasting material has a certain service life. Therefore, in order to reduce production costs, the sandblasting material can leave the accommodating cavity through the hollow hole 4, which also facilitates the collection of the sandblasting material for subsequent use.

[0049] In this embodiment, the first housing 1 is provided with an observation window 14, which is covered by an acrylic plate 5. As will be appreciated, the acrylic plate 5 has excellent transparency and weather resistance, allowing for real-time monitoring of the status of the heat sink material 100 during the sandblasting process, thereby ensuring a high yield rate for the heat sink material 100.

[0050] In actual application, multiple heat sink materials 100 are placed in the second receiving groove 21 of the second shell 2 in sequence, and then the sandblasting gun head 200 is installed to the opening 11 of the first shell 1, and the first shell 1 and the second shell 2 are assembled into a receiving cavity through the connecting member 3. After the sandblasting is completed, the first shell 1 and the second shell 2 are separated, and the sandblasting of the heat sink material 100 is checked and turned over, and then the above operation is repeated to ensure that the surface of the heat sink material 100 is evenly sandblasted.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
