[0032] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] like Figure 1 and Figure 2 As shown, in one embodiment, the hanger 10 includes a first support plate 1 and a plurality of first clips 2; each first clip 2 is spaced apart on the first support plate 1; in the extending direction of the first support plate 1, at least one of the two outermost first clips 1 is a first movable clip 21, which can move along the extending direction of the first support plate 1, thereby enabling the position adjustment of the first movable clip 21 in that direction.

[0035] exist Figure 1 In the directions shown, the extension direction of the first support plate is parallel to the X-axis.

[0036] "Multiple" means two or more. The meaning of the word "multiple" is the same in all embodiments and will not be repeated hereafter.

[0037] During operation, the PCB 20 can be clamped using the first clamp 2. Since the outermost first movable clamp 21 of each first clamp 2 can be adjusted in the X-axis direction, the position of the first movable clamp 21 can be adjusted according to the actual size of the PCB 20 to be clamped in the X-axis direction, so that the first movable clamp 21 can clamp the PCB 20 in a suitable position in the X-axis direction, thereby improving the adaptability to PCBs of different sizes and types.

[0038] It should be understood that, in actual use, the first clamp 2 can also be used to clamp other materials.

[0039] In addition, each of the first clips 2 is actually arranged at intervals along the X-axis. "The two outermost first clips 2" refers to the two outermost first clips 2 that are arranged at intervals along the X-axis.

[0040] "The first movable clamp 21 can move along the extension direction of the first support plate 1" means that the first movable clamp 21 can move relative to the first support plate 1 along the X-axis.

[0041] like Figure 3 As shown, in one embodiment, the first support plate 1 is provided with a receiving cavity 11; the first movable clamp 21 includes a connecting rod 211, which passes through the receiving cavity 11 and can move within the receiving cavity 11 along the extending direction of the first support plate 1, thereby realizing the movement of the first movable clamp 21 along the extending direction of the first support plate 1.

[0042] The cavity wall of the receiving cavity 11 can shield and protect the connecting rod 211, thereby preventing the connecting rod 211 from being deformed or damaged by collisions with external objects, and ensuring the smooth movement of the first movable clamp 21 along the X-axis.

[0043] like Figure 1 As shown, in one embodiment, the first support plate 1 has a first surface 12 and a second surface 13 arranged opposite to each other in the X-axis direction. When there is only one first movable clip 21, the receiving cavity 11 that mates with it can be provided on the first surface 12 or on the second surface 13; moreover, the receiving cavity 11 can be a blind hole structure or a through hole structure penetrating the first surface 12 and the second surface 13. When the two outermost first clips 2 are both first movable clips 21; if the receiving cavity 11 is a blind hole structure, then the first surface 12 and the second surface 13 are both provided with receiving cavities 11 so as to respectively mate with and install the corresponding first movable clips 21; if the receiving cavity 11 is a through hole structure penetrating the first surface 12 and the second surface 13, then only one receiving cavity 11 needs to be provided on the first support plate 1 to achieve mating with the two first movable clips 21.

[0044] like Figure 3 As shown, in one embodiment, the first support plate 1 is provided with a mounting hole 14 communicating with the receiving cavity 11, and the first support plate 1 has a pressing member 3 and a first elastic member 4; the pressing member 3 passes through the mounting hole 14 and the receiving cavity 11, one end of the pressing member 3 abuts against the outer surface of the first support plate 1, the other end of the pressing member 3 abuts against the connecting rod 211, and the first elastic member 4 is sleeved on the pressing member 3 and received in the receiving cavity 11.

[0045] In this embodiment, the first elastic element 4 provides a preload force so that the pressing element 3 abuts against the connecting rod 211. This allows the static friction between the pressing element 3 and the connecting rod 211 to keep the connecting rod 211 in the corresponding position on the first support plate.

[0046] Furthermore, after the pressing member 3 abuts against the connecting rod 211, the connecting rod 211 can also be pressed onto the first support plate 1. In this way, the static friction between the first support plate 1 and the connecting rod 211 can also keep the connecting rod 211 in the corresponding position on the first support plate 1.

[0047] In addition, "the other end of the pressing member 3 abuts against the connecting rod 211" can mean that the other end of the pressing member 3 is located in the receiving cavity 11 and abuts against the connecting rod 211 in the receiving cavity 11.

[0048] Moreover, in some scenarios, when the pressing member 3 abuts against the connecting rod 211, the pressing member 3 may not abut against the outer surface of the first support plate 1.

[0049] In one embodiment, the first elastic element 4 may be a helical spring or the like.

[0050] like Figure 3 As shown, in one embodiment, the pressing member 3 includes a first abutment 31, a second abutment 32, and a connecting member 33. The connecting member 33 connects the first abutment 31 and the second abutment 32. The mounting hole 14 passes through the first support plate 1. The connecting member 33 passes through the mounting hole 14. The first abutment 31 abuts against the outer surface of the first support plate 1. The second abutment 32 abuts against the connecting rod 211. One end of the first elastic member 4 abuts against the second abutment 32, and the other end abuts against the inner wall of the first support plate 1.

[0051] During operation, the first elastic element 4 is compressed between the second abutment 32 and the inner wall of the first support plate 1. The elastic force of the first elastic element 4 can press the second abutment 32 onto the connecting rod 211, thereby achieving contact between the pressing element 3 and the connecting rod 211. The inner wall of the first support plate 1 is the cavity wall of the receiving cavity 11, which together form the receiving cavity 11.

[0052] By having the first stopper 31 abut against the outer surface of the first support plate 1, the pressing member 3 can be prevented from moving out of the mounting hole 14 in the direction from the outside to the inside.

[0053] The first abutting member 31 abuts against the outer surface of the first support plate 1, thereby achieving the above-mentioned "one end of the pressing member 3 abuts against the outer surface of the first support plate 1".

[0054] like Figure 1As shown, in one embodiment, the first movable clamp 21 further includes a first body 212, which is used to clamp target objects such as PCBs. That is, the first movable clamp 21 actually clamps the PCB through the first body 212, and the first body 212 is connected to the first support plate 1 through a connecting rod 211.

[0055] like Figure 1 As shown, in one embodiment, in the X-axis direction, the two outermost first clips 2 of each first clip 2 are both first movable clips 21, which can further improve the adaptability of the hanger 10 to PCBs of different sizes and types.

[0056] like Figure 1 As shown, in one embodiment, each first clip 2 further includes a first fixing clip 27; in the X-axis direction, the first fixing clip 27 is fixed at its mounting position on the first support plate 1. This improves the clamping and fixing effect on the PCB. In this case, the number of first clips 2 in the hanger 10 is greater than or equal to three.

[0057] The phrase "the first fixing clip 27 is fixed in the mounting position on the first support plate 1 in the X-axis direction" can mean that the relative positions of the first fixing clip 27 and the first support plate 1 in the X-axis direction are fixed. Specifically, the mounting position of the first fixing clip 27 on the first support plate 1 is fixed.

[0058] It should be understood that when there are two first clips 2 in the hanger 10, each first clip 2 can be a first movable clip 21; or, one of the two first clips 2 can be a first fixed clip 27 and the other can be a first movable clip 21. When there are three or more first clips 2 in the hanger 10, in the X-axis direction, except for the outermost first clip 2, any other first clip 2 can be either a first movable clip 21 or a first fixed clip 27.

[0059] In addition, the structure of the first fixing clip 27 can be the same as the structure of the first body 212.

[0060] like Figure 2As shown, in one embodiment, the first clamping clamp 27 includes a mounting plate 22, a support base 23, a first clamping arm 24, a second clamping arm 25, and a spring 26. The mounting plate 22 can be connected to the first support plate 1. The support base 23 and the first clamping arm 24 are both connected to the mounting plate 22. The second clamping arm 25 is mounted on the support base 23 and can rotate relative to the support base 23 around a first axis, wherein the first axis is parallel to the X-axis. The spring 26 connects the second clamping arm 25 and the mounting plate 22 respectively, and initially, the spring 26 is in an elastic deformation state. The elastic force of the spring 26 causes the second clamping arm 25 to rotate relative to the support base 23. 5. The first clamping arm 24 can be engaged. In use, force can be applied to the second clamping arm 25 to rotate it and disengage it from engaging the first clamping arm 24. Then, the PCB is placed between the first clamping arm 24 and the second clamping arm 25. Then, the force applied to the second clamping arm 25 is removed, and the second clamping arm 25 can return to its original position under the action of the spring 26. When there is a PCB between the first clamping arm 24 and the second clamping arm 25, the second clamping arm 25 can press the PCB against the first clamping arm 24, thereby achieving the clamping of the PCB by the first clamping arm 24 and the second clamping arm 25, that is, achieving the clamping of the PCB by the first fixing clamp 27. The first fixing clamp 27 can also adopt other existing designs, and this embodiment will not be described in detail here.

[0061] In one embodiment, in the thickness direction of the first support plate 1, each first clip 2 may be disposed on the same side of the first support plate 1. The thickness direction of the first support plate 1 may be perpendicular to the extension direction of the first support plate 1. Figure 1 In the directions shown, the thickness direction of the first support plate 1 is parallel to the Y-axis.

[0062] like Figure 1 and Figure 4 As shown, in one embodiment, the hanger 10 further includes a second support plate 5, a second clip 6, and a connecting assembly 7; the second support plate 5 and the first support plate 1 are disposed opposite to each other; one end of the connecting assembly 7 is movably connected to the first support plate 1, and the other end is connected to the second support plate 5, so that the second support plate 5 can move relative to the first support plate 1; the second clip 6 is connected to the second support plate 5; the second clip 6 and the first clip 2 can simultaneously clamp the same PCB. In use, the first clip 2 clamps one end of the PCB, and the second clip 6 clamps the other end of the PCB, thereby improving the clamping effect on the PCB.

[0063] Of course, when the PCB is other materials, the second clamp 6 and the first clamp 2 can clamp the material at the same time.

[0064] In one embodiment, the second support plate 5 and the first support plate 1 are spaced apart in the height direction of the first support plate 1, wherein the height direction, the thickness direction, and the extension direction of the first support plate 1 are perpendicular to each other.

[0065] exist Figure 1 In the directions shown, the height direction of the first support plate 1 is parallel to the Z-axis, where the Z-axis direction can be up or down.

[0066] In addition, the second support plate 5 being movable relative to the first support plate 1 means that the second support plate 5 is movable relative to the first support plate 1 in the height direction of the first support plate 1.

[0067] In one embodiment, the number of connecting components 7 is one or more. When the number of connecting components 7 is multiple, each connecting component 7 may be arranged sequentially at intervals along the extending direction of the first support plate 1.

[0068] like Figure 1 As shown, in one embodiment, the hanger 10 includes a plurality of second clips 6, each second clip 6 being spaced apart on the second support plate 5 along the extending direction of the first support plate 1; in the extending direction of the first support plate 1, at least one of the two outermost second clips 6 is a second movable clip 61; the second movable clip 61 is movable along the extending direction of the first support plate 1. This allows each second clip 6 to be clamped at a suitable position on the PCB along the X-axis, thereby improving the adaptability to PCBs of different sizes and types.

[0069] The structure of the second support plate 5 can be the same as that of the first support plate 1, the structure of the second movable clamp 61 can be the same as that of the first movable clamp 21, and the connection method between the second movable clamp 61 and the second support plate 5 can be the same as that between the first movable clamp 21 and the first support plate 1.

[0070] In one embodiment, in the extending direction of the first support plate 1, the two outermost second clips 6 of each second clip 6 are both second movable clips 61, which can further improve the adaptability of the hanger 10 to PCBs of different sizes and types.

[0071] like Figure 1 As shown, in one embodiment, each second clip 6 further includes a second fixing clip 62; the second fixing clip 62 remains fixed in relative position to the second support plate 5 in the extending direction of the first support plate 1. This improves the clamping and fixing effect on the PCB. In this case, the number of second clips 6 in the hanger 10 is greater than or equal to three.

[0072] The phrase "the relative position of the second fixing clip 62 and the second support plate 5 remains fixed in the extension direction of the first support plate 1" can mean that the second fixing clip 62 is fixed in its installation position on the second support plate 5, and after assembly, the second fixing clip 62 cannot move relative to the second support plate 5 in the extension direction of the first support plate 1.

[0073] It should be understood that when there are two second clips 6 in the hanger 10, each second clip 6 can be a second movable clip 61; or, one of the two second clips 6 is a second fixed clip 62 and the other is a second movable clip 61.

[0074] In addition, the structure of the second fixing clip 62 can be the same as that of the first fixing clip 27.

[0075] like Figure 1 and Figure 4 As shown, in one embodiment, the hanger 10 further includes a pre-tightening component 8. The first support plate 1 has a first through hole 15 along the extending direction of the connecting component 7. The connecting component 7 passes through the first through hole 15, and the pre-tightening component 8 is used to fix the position of the connecting component 7. The extending direction of the connecting component 7 is the height direction of the first support plate 1.

[0076] In real-world scenarios, when the PCB is a flexible or thin board, it may undulate after being clamped by the hanger, resulting in an uneven PCB. To address this, in this embodiment, the position of the connecting component 7 within the first through hole 15 can be adjusted. Simultaneously, the pre-tightening component 8 allows the connecting component 7 to move the second support plate 5 and the second clamp 6 away from the first support plate 1, thereby tensioning the PCB clamped by the first clamp 2 and the second clamp 6. This ensures a flat PCB, improving the subsequent electroplating effect.

[0077] Furthermore, when there are multiple connecting components 7, there can also be multiple pre-tightening components 8, wherein each pre-tightening component 8 corresponds one-to-one with a connecting component 7, and the connecting component 7 and its corresponding pre-tightening component 8 cooperate with each other. Of course, in this case, there are also multiple first through holes 15, each first through hole 15 corresponds one-to-one with a connecting component 7, and the connecting component 7 passes through its corresponding first through hole 15.

[0078] The first through hole extends through the first support plate 1 along the Z-axis.

[0079] like Figure 2As shown, in one embodiment, the pre-tightening component 8 includes a second elastic element 81, a fastener 82, and a bracket 83. The connecting component 7 is provided with a protrusion 71, the cross-sectional area of ​​which is larger than the cross-sectional area of ​​the first through hole 15. Along the extending direction of the connecting component 7, the second elastic element 81, the bracket 83, and the fastener 82 are sequentially sleeved on the connecting component 7. One end of the second elastic element 81 abuts against the protrusion 71, and the other end of the second elastic element 81 abuts against the bracket 83. The bracket 83 is installed on the first support plate 1 and is provided with a second through hole 831. The cross-sectional area of ​​the fastener 82 is larger than the cross-sectional area of ​​the second through hole 831. The position of the fastener 82 on the connecting component 7 is adjustable.

[0080] The connecting component 7 passes through the bracket 83 through the second through hole 831, thereby allowing the bracket 83 to be fitted onto the connecting component 7. Moreover, the second through hole 831 can penetrate the bracket 83 along the Z-axis direction.

[0081] In the Z-axis direction, the fastener 82 is located on the side of the bracket 83 opposite to the second elastic member 81, and the protrusion 71 is located on the side of the second elastic member 81 opposite to the fastener 82. The second elastic member 81 is compressed between the bracket 83 and the protrusion 71. Under the elastic force of the second elastic member 81, the connecting assembly 7 can drive the fastener 82 to move along the direction from the fastener 82 to the protrusion 71, and eventually make the fastener 82 abut against the bracket 83. Moreover, when the connecting assembly 7 drives the fastener 82 to move along the direction from the fastener 82 to the protrusion 71, it can also drive the second support plate 5 to move along the direction from the fastener 82 to the protrusion 71, away from the first support plate 1. When the fastener 82 abuts against the bracket 83, the distance between the first support plate 1 and the second support plate 5 is at its maximum.

[0082] During operation, after the first clamp 2 and the second clamp 6 clamp the PCB, the second support plate 5 can be moved to the position furthest away from the first support plate 1 under the action of the second elastic member 81, thereby tensioning the clamped PCB.

[0083] In addition, since the position of the fastener 82 in the connecting component 7 is adjustable, the distance between the first support plate 1 and the second support plate 5 is adjustable, thus enabling the tensioning of PCBs of different sizes.

[0084] Furthermore, the cross-sectional area of ​​the protrusion 71 is larger than that of the first through hole 15, so when the protrusion 71 moves toward the first through hole 15, the protrusion 71 can abut against the hole wall (i.e., the first support plate 1) of the first through hole 15.

[0085] In one embodiment, the connecting component 7 may be a rod-shaped structure, the protrusion 71 may be disposed on its side, and the protrusion 71 may be disposed around the connecting component 7.

[0086] In one embodiment, in the Z-axis direction, the fastener 82, the second elastic element 81, and the protrusion 71 are all located on the side of the first support plate 1 away from the second support plate 5.

[0087] like Figure 2 As shown, in one embodiment, the connecting component 7 includes a stud 72, a second elastic element 81, a bracket 83 and a fastener 82 sequentially sleeved on the stud 72.

[0088] Among them, the fastener 82 can be a nut, which is threaded with the stud 72, thereby realizing the connection between the fastener 82 and the connecting component 7.

[0089] In addition, when the connecting component 7 is a rod-shaped structure, the stud 72 may only be a part of its axial structure.

[0090] This utility model embodiment also provides an electroplating device, which includes the hanger 10 described in any of the above embodiments. This electroplating device can be used for electroplating PCBs; specifically, it can be a vertical continuous electroplating device.

[0091] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
