[0033] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] It should be noted that if the embodiments of this utility model involve directional indication, the directional indication is only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] The commonly used cleaning method in ultrasonic cleaning of semiconductor and integrated circuit packaging is suspension cleaning. Packaging shell products are usually designed with mounting holes or mounting slots. For ease of description, these mounting holes and mounting slots are collectively referred to as mounting recesses. The number and location of mounting recesses vary greatly among different types of packaging shell products. Therefore, special cleaning racks are usually required for different packaging shell products. The special cleaning racks are equipped with pins corresponding to the positions of the mounting recesses. Multiple mounting recesses on the packaging shell product are fitted into the corresponding pins on the special cleaning rack to mount the packaging shell product onto the special cleaning rack.

[0038] However, the products that can be mounted on the special cleaning racks are relatively limited. When there are many types of products on the production line, a large number of special cleaning racks of various models occupy a lot of production space and will also lead to an increase in the idle rate of the special cleaning racks.

[0039] In view of this, the present invention proposes an adjustable hanger. This adjustable hanger has many applications. If applied to ultrasonic cleaning, it can at least improve the limitation of existing dedicated cleaning hangers in terms of the range of products they can support. Of course, this adjustable hanger can also be used in electroplating applications. For ease of understanding, the following description is provided in conjunction with the accompanying drawings. Figure 1 A schematic diagram of the structure of an embodiment of the adjustable hanger provided by this utility model; Figure 2 for Figure 1 A schematic diagram of the structure of the first adjustment part and the second adjustment part in the middle; Figure 3 for Figure 2 The exploded structure diagram of the second adjustment part and the hanging pin.

[0040] In one embodiment of this utility model, the adjustable hanger 100 includes a hanger 1, a plurality of first adjustment parts 2 and a plurality of second adjustment parts 3. The plurality of first adjustment parts 2 extend along the vertical direction Z and are spaced apart on the hanger 1 in the horizontal direction X. The distance between two adjacent first adjustment parts 2 is adjustable. The plurality of second adjustment parts 3 are respectively disposed on the plurality of first adjustment parts 2. The position of the second adjustment parts 3 in the vertical direction Z is adjustable. The second adjustment parts 3 are provided with a hanging pin 4 extending along the front-back direction Y. The hanging pin 4 is used for hanging the product 200 to be hung.

[0041] It should be noted that the multiple first adjustment parts 2 extend along the vertical direction Z and are spaced apart in the horizontal direction X, which can be understood as a grid structure; "the spacing between two adjacent first adjustment parts 2 is adjustable" means that each first adjustment part 2 can be adjusted in position along the horizontal direction X on the bracket 1, so that the spacing between two adjacent first adjustment parts 2 in the horizontal direction X is adjustable; there are various ways to adjust the movement of the first adjustment parts 2 on the bracket 1, for example, a guide rail extending along the horizontal direction X is provided on the bracket 1, and a slider is provided on each first adjustment part 2. The slider is connected to the guide rail to realize the position adjustment of the first adjustment part 2. This embodiment does not limit this; "multiple second adjustment parts 3 are respectively provided on multiple first adjustment parts 2", the number of second adjustment parts 3 should not be less than the number of first adjustment parts 2 to ensure that at least one second adjustment part 3 is provided on each first adjustment part 2; the movement adjustment method of the second adjustment parts 3 on the first adjustment parts 2 There are multiple ways to achieve this. For example, a guide rail extending in the vertical direction Z can be provided on the first adjustment part 2, and a slider can be provided on each second adjustment part 3. The slider is connected to the guide rail to adjust the position of the second adjustment part 3. This embodiment does not limit this. It should be noted that the second adjustment part 3 can at least remain in the corresponding position after the position is adjusted so that the product 200 to be hung can be hung stably. There are also multiple ways to maintain the position of the second adjustment part 3. For example, it can be fixed by snap-fit ​​structure or by pull rope structure. The above two fixing methods are more common and will not be described in detail in this embodiment. "The second adjustment part 3 is provided with a hanging pin 4 extending in the front-back direction Y" means that the hanging pin 4 has a first end 41 and a second end 42 in the front-back direction Y. The first end 41 is provided on the second adjustment part 3 and extends away from the second adjustment part 3 in the front-back direction Y, so that the hanging recess of the product 200 to be hung can be fitted into it for hanging.

[0042] Since the mounting recesses of the product to be mounted 200 are usually provided, and the multiple mounting recesses may be arranged at intervals along the left-right direction X, by adjusting the mutual spacing of the corresponding multiple first adjustment parts 2, the setting positions of the multiple first adjustment parts 2 can be made to correspond with the multiple mounting recesses of the product to be mounted 200, for example... Figure 1 As shown, the product to be mounted 200 has two mounting recesses in the left-right direction X, and the mounting requirements of the product to be mounted 200 can be met by the corresponding two first adjustment parts 2.

[0043] In the technical solution provided by this utility model, by adjusting the distance between two adjacent first adjustment parts 2, the second adjustment part 3 on the first adjustment part 2 can be moved to adjust its position in the left-right direction X. Combined with adjusting the position of the second adjustment part 3 in the extension direction (i.e., the up-down direction Z) of the first adjustment part 2, the hanging pin 4 set on the second adjustment part 3 can be adjusted to any position in the vertical plane of the hanger 1. That is, the position adjustment of the hanging pin 4 for different models of products 200 to be hung is realized, thereby improving the range of products applicable to the adjustable hanger 100. Moreover, since the adjustable hanger 100 can be used for multiple models of products 200 to be hung, it is beneficial to reduce the idle rate of the adjustable hanger 100, thereby reducing the number of adjustable hangers 100 set on the production line, and thus reducing the space occupied by the adjustable hanger 100.

[0044] In one application scenario, the adjustable hanger 100 is used as a hanger for electroplating products. The first adjustment part 2, the second adjustment part 3 and the hanging pin 4 are all made of conductive metal. By energizing the first adjustment part 2, electroplating operations can be performed on the product 200 to be hung.

[0045] Please see Figure 3 In one embodiment, the hanging pin 4 has a first end 41 in the front-rear direction Y, and the first end 41 is connected to the second adjustment part 3 by a threaded pair.

[0046] It should be noted that the "threaded pair" includes the threaded hole 32b (internal thread) and the threaded rod 41a (external thread). "The first end 41 is connected to the second adjusting part 3 via the threaded pair" can be understood as the first end 41 having a threaded hole 32b and the second adjusting part 3 having a threaded rod 41a; or it can be understood as the first end 41 being a threaded rod 41a and the second adjusting part 3 having a threaded hole 32b (e.g., Figure 3 (As shown in the figure), this embodiment does not limit this.

[0047] According to the above technical solution, the first end 41 of the hanging pin 4 is connected to the second adjustment part 3 through a threaded pair, realizing the detachable connection between the hanging pin 4 and the second adjustment part 3. This facilitates the maintenance and replacement of the hanging pin 4, can improve the service life of the adjustable cleaning hanger, and reduce the cost of use.

[0048] Please see Figure 2 In one embodiment, the first adjustment part 2 has a plurality of connecting parts 22 arranged at intervals in the vertical direction Z; the second adjustment part 3 has a mating part 32, which is configured to be selectively connected to one of the connecting parts 22, so that the second adjustment part 3 is fixed to the position of the corresponding connecting part 22.

[0049] It should be noted that this embodiment only limits the second adjustment part 3 to be connected to the connecting part 22 on the first adjustment part 2 through the mating part 32, but does not limit the specific structural form of the mating part 32 and the connecting part 22. For example, the connecting part 22 is a connecting hook, and the mating part 32 is a mating hook groove. The second adjustment part 3 and the first adjustment part 2 are detachably connected by a hook lock. This embodiment does not limit this.

[0050] According to the above technical solution, the second adjustment part 3 can be selectively connected to one of the multiple connecting parts 22 on the first adjustment part 2 through the mating part 32, and the position adjustment of the second adjustment part 3 on the first adjustment part 2 can be realized through a simple and reliable structure.

[0051] Please see Figure 2 In one embodiment, the connecting part 22 includes a connecting hole 22a that extends through in the left-right direction X; the mating part 32 includes a mating hole 32a that extends through in the left-right direction X, and the mating hole 32a and the connecting hole 22a are connected by the plug-in part 5.

[0052] It should be noted that the connecting hole 22a on the first adjusting part 2 and the mating hole 32a on the second adjusting part 3 are both through in the left-right direction X, so that the plug part 5 can be inserted into the connecting hole 22a and the mating hole 32a in sequence, thereby connecting the first adjusting part 2 and the second adjusting part 3; the specific structure of the plug part 5 can be a simple pin or a screw. When the plug part 5 is a screw, one of the connecting hole 22a and the mating hole 32a can be set as a screw hole.

[0053] According to the above technical solution, the first adjustment part 2 and the second adjustment part 3 are respectively provided with a connecting hole 22a and a mating hole 32a. The two can be easily disassembled and connected through the insertion part 5, which ensures the efficient operation of the position adjustment process of the hanging pin 4.

[0054] Please see Figure 2 In one embodiment, the first adjustment part 2 has two mounting walls 21 extending in the vertical direction Z, the two mounting walls 21 are spaced apart in the horizontal direction X, and at least one of the mounting walls 21 is provided with a plurality of connecting holes 22a; the second adjustment part 3 has a mounting base 31 located between the two mounting walls 21, and mating holes 32a are formed in the mounting base 31.

[0055] It should be noted that the mounting wall 21 is part of the structure of the first adjustment part 2. Since the two mounting walls 21 are spaced apart in the left-right direction X, an installation space can be defined between the two mounting walls 21. Combined with the fact that the mounting walls 21 extend in the up-down direction Z, this allows the mounting base 31 of the second adjustment part 3 to move and adjust in the up-down direction Z within the installation space. "At least one of the mounting walls 21 is provided with multiple connecting holes 22a" means that multiple connecting holes 22a arranged in the up-down direction Z can be provided on only one mounting wall 21, or multiple connecting holes 22a arranged in the up-down direction Z can be provided on both mounting walls 21 respectively. In the latter case, both mounting walls 21 can provide a base for the insertion part 5, thereby fixing the second adjustment part 3 to the two mounting walls 21.

[0056] According to the above technical solution, by setting two mounting walls 21, the degree of freedom of the second adjustment part 3 in the left-right direction X can be restricted, thereby improving the structural stability of the adjustable hanger 100 and the reliability of the mounting.

[0057] Please see Figure 3 In one embodiment, the second adjustment part 3 also has two mounting ends 33 in the front-rear direction Y, and the mounting base 31 is located between the two mounting ends 33; two hanging pins 4 are provided corresponding to the second adjustment part 3, and the two hanging pins 4 are respectively mounted on the two mounting ends 33.

[0058] According to the above technical solution, by setting two mounting ends 33, a mounting base can be provided for two hanging pins 4, realizing the purpose of hanging the product 200 to be hung on the front and rear sides of the second adjustment part 3 respectively, thereby improving the hanging capacity of the adjustable hanger 100 and further reducing the number of adjustable hangers 100 on the production line.

[0059] Please see Figure 3 In one embodiment, the second adjustment part 3 further has a mounting end 33 on the Y side in the front-rear direction. The mounting end 33 has an abutting part 331 protruding in the X side in the left-right direction. The abutting part 331 abuts against the corresponding end face of the mounting wall 21 on the Y side in the front-rear direction.

[0060] It should be noted that the two mounting walls 21 are opposite each other in the left-right direction X. The mounting base 31 of the second adjustment part 3 is disposed between the two mounting walls 21. The mounting end 33 is located on one side of the mounting base 31 in the front-back direction Y. At this time, the mounting end 33 is also located on one side of the two mounting walls 21 in the front-back direction Y. The mounting end 33 has an abutting part 331 protruding in the left-right direction X. The abutting part 331 can abut against the mounting wall 21 in the front-back direction Y.

[0061] According to the above technical solution, the abutting part 331 protruding along the left-right direction X on the mounting end 33 can abut against the side wall of the mounting wall 21 in the front-back direction Y, which is equivalent to playing the role of anti-rotation and limiting. In conjunction with the insertion part 5 to limit the connection between the first adjustment part 2 and the second adjustment part 3, the second adjustment part 3 can be stably fixed on the first adjustment part 2. The abutting part 331 has a simple abutting and fixing structure and high reliability.

[0062] Please see Figure 1 In one embodiment, the bracket 1 includes a mounting beam 11, on which a mounting hole 11a is formed that runs through in the vertical direction Z and is elongated in the horizontal direction X; a first adjustment part 2 passes through the mounting hole 11a, and a limiting part 23 protruding in the front-back direction Y is formed at the upper end of the first adjustment part 2, and the limiting part 23 abuts against the upper end surface of the mounting beam 11.

[0063] According to the above technical solution, the first adjustment part 2 extends along the vertical direction Z and can pass through the mounting hole 11a on the mounting beam 11. Since the upper end of the first adjustment part 2 forms a limiting part 23, the first adjustment part 2 can be limited and fixed by the abutting contact between the limiting part 23 and the mounting beam 11. Since the mounting hole 11a is elongated in the left-right direction X, the first adjustment part 2 has a movable adjustment stroke in the left-right direction X. This adjustment structure is relatively simple and has a low manufacturing cost.

[0064] Please continue reading. Figure 1 In one embodiment, an opening groove 11b is formed on one side of the mounting beam 11 in the front-rear direction Y. The opening groove 11b is connected to the mounting hole 11a and is provided through in the vertical direction Z. The distance between the two groove sidewalls of the opening groove 11b in the left-right direction X is D1. The first adjustment part 2 has a snap-fit ​​section 24 in the vertical direction Z. The width of the snap-fit ​​section 24 in the left-right direction X is D2, wherein D1≥D2.

[0065] It should be noted that "the mounting beam 11 has an opening groove 11b formed on one side of the front-rear direction Y, the opening groove 11b connects to the mounting hole 11a, and is arranged through the vertical direction Z" can also be understood as follows: since the mounting hole 11a is elongated in the left-right direction X, the mounting beam 11 has two opposing beam sidewalls in the front-rear direction Y, the mounting hole 11a is located between the two beam sidewalls, and one of the beam sidewalls is disconnected in the left-right direction X, so that the opening groove 11b is formed at the disconnection; since the first adjustment part 2 extends in the vertical direction Z, the snap-fit ​​section 24 refers to one section of the first adjustment part 2 in the vertical direction Z, and the width D2 of the snap-fit ​​section 24 in the left-right direction X can be less than or equal to the width of other sections, for example, in Figure 2 As shown, the snap-fit ​​segment 24 is significantly smaller in width than the other segments.

[0066] According to the above technical solution, by setting the opening slot 11b and limiting the distance D1 between the two slot sidewalls of the opening slot 11b in the left-right direction X to be greater than or equal to the width D2 of the snap-fit ​​section 24 in the left-right direction X, the first adjustment part 2 can be snapped into the opening slot 11b through its snap-fit ​​section 24 and enter the mounting hole 11a. Compared with the solution where the first adjustment part 2 is installed from top to bottom through the mounting hole 11a, this setting method can significantly reduce the installation difficulty of the first adjustment part 2 on the hanging beam 11.

[0067] Please see Figure 2 In one embodiment, the first adjusting part 2 further includes a main body section 25 located between the snap-fit ​​section 24 and the limiting part 23. The width of the main body section 25 in the left-right direction X is D3, where D3 > D1. With this configuration, after the first adjusting part 2 snaps into the opening slot 11b through the snap-fit ​​section 24 and enters the mounting hole 11a, under the action of gravity, the first adjusting part 2 continues to fall until the limiting part 23 abuts against the hanging beam 11. At this time, the main body section 25 is in the mounting hole 11a. This makes it difficult for the first adjusting part 2 to fall off the hanging beam 11 when it is adjusted to the position of the opening slot 11b in the left-right direction X, since the width of the main body section 25 is greater than the distance between the two sidewalls of the opening slot 11b.

[0068] Please see Figure 2 In one embodiment, the opening slot 11b is positioned at the center of the mounting hole 11a in the left-right direction X. It should be noted that since the mounting hole 11a is elongated in the left-right direction X, the opening slot 11b breaks one side wall of the hanging beam 11 in the front-rear direction Y into two cantilever segments. In this design, the opening slot 11b is positioned at the center of the mounting hole 11a, which balances the lengths of the two cantilever segments, improving the rigidity of the hanging beam 11 and ensuring the structural stability of the bracket 1.

[0069] It should be noted that the two parallel technical features mentioned above, "the first adjustment part 2 also has a main body section 25 located between the snap-fit ​​section 24 and the limiting part 23, and the width of the main body section 25 in the left-right direction X is D3, where D3>D1" and "in the left-right direction X, the opening groove 11b is set at the middle of the mounting hole 11a", can be set either one or both. Obviously, setting both at the same time is better.

[0070] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
