When the small-size fine-tuning frame clamps the PCB board, it is relatively stable, and the rack shakes less during pushing, but its versatility is poor. The large-size adjustable openable frame has strong versatility, but during pushing, the clamped PCB board may be torn and damaged due to relative displacement between the upper and lower cross beams.

[0012] As a further technical solution, the limiting assembly includes a positioning rod, and the first end of the support rod is provided with a plurality of positioning holes spaced apart along its axial direction, and the positioning rod can pass through the corresponding avoidance hole and be inserted into the positioning hole.

[0013] As a further technical solution, the lower cross beam assembly includes a lower fixed plate, a support leg and a plurality of connecting members, the support leg is connected to the lower fixed plate through the plurality of connecting members, and the plurality of connecting members are staggered with each other.

[0030] The present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present utility model, rather than limiting the present utility model. Additionally, it should be noted that for the sake of description, only the parts related to the present utility model rather than all the structures are shown in the accompanying drawings.

[0031] In the description of the present utility model, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" shall be understood in a broad sense.

[0032] In the present utility model, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween.

It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meanings.

[0034] Specific combination Figures 1 to 6As shown in the figure, the PCB electroplating hanger provided in this embodiment is used for PCB electroplating, has strong versatility, and can avoid the situation of tearing and damage to the PCB. Specifically, the PCB electroplating hanger includes a conductive frame 100 and a limiting component 200. The conductive frame 100 includes an upper crossbeam component 110, a lower crossbeam component 120, and two support rods 130. Along the height direction, the upper crossbeam component 110 is movably connected to the upper ends of the two support rods 130. An avoidance hole 101 is provided on the upper crossbeam component 110. The lower ends of the two support rods 130 are both connected to the lower crossbeam component 120. The limiting component 200 is connected to the upper crossbeam component 110 and can pass through the avoidance hole 101 to be in limiting connection with the support rod 130 to limit the relative position between the upper crossbeam component 110 and the support rod 130.

[0035] Since the upper crossbeam component 110 is movably arranged, changing the relative distance between the upper crossbeam component 110 and the lower crossbeam component 120 can clamp PCB boards of different heights for electroplating, thereby improving the versatility of the PCB electroplating hanger. Since the limiting component 200 is provided on the upper crossbeam component 110 and the limiting component 200 can pass through the avoidance hole 101 to be in limiting connection with the support rod 130; therefore, when hanging the PCB board on the PCB electroplating hanger, first disconnect the connection between the limiting component 200 and the support rod 130, then move the upper crossbeam component 110 upward, then hang the PCB board between the upper crossbeam component 110 and the lower crossbeam component 120, and adjust the relative position between the upper crossbeam component 110 and the lower crossbeam component 120 to straighten the PCB board, and then make the limiting component 200 be in limiting connection with the support rod 130 again; thereby restricting the relative position between the upper crossbeam component 110 and the support rod 130, so as to restrict the relative position between the upper crossbeam component 110 and the lower crossbeam component 120, and further, during the process of the PCB electroplating hanger being pushed, the situation that the relative position between the upper crossbeam component 110 and the lower crossbeam component 120 changes and causes the PCB board to be torn and damaged can be avoided.

[0036] In this embodiment, the upper crossbeam component 110 includes an upper fixing plate 111 and two sleeves 112. The two sleeves 112 are respectively movably sleeved on the first ends of the two support rods 130. The two ends of the upper fixing plate 111 are respectively connected to the two sleeves 112; avoidance holes 101 are provided on both of the two sleeves 112. Correspondingly, there are two groups of limiting components 200, and the two groups of limiting components 200 are arranged on the two sleeves 112 in one-to-one correspondence with the two avoidance holes 101, so as to restrict the relative position between the upper crossbeam component 110 and the support rod 130 from both ends of the upper fixing plate 111.

[0037] Further, the limiting component 200 includes a clamping member 210, a limiting member 220, and a reset member 230. The middle part of the clamping member 210 is rotatably connected to the upper crossbeam assembly 110. The reset member 230 is arranged between the second end of the clamping member 210 and the upper crossbeam assembly 110. The limiting member 220 is fixedly connected to the first end of the clamping member 210 and can pass through the avoidance hole 101 to be in limiting connection with the corresponding support rod 130.

[0038] Taking one group of the limiting components 200 as an example, specifically, the middle part of the clamping member 210 is rotatably connected to the sleeve 112 through a bearing seat (not shown in the figure). The limiting member 220 is fixedly connected to the first end of the clamping member 210 and is perpendicularly arranged with the first end of the clamping member 210. The reset member 230 is arranged between the second end of the clamping member 210 and the outer wall of the sleeve 112. When it is necessary to hang the PCB board, press the second end of the clamping member 210, and the reset member 230 is compressed and deformed. At the same time, as the clamping member 210 rotates around the bearing seat, the limiting member 220 is disengaged from the limiting connection with the support rod 130. After the PCB board is hung on the PCB board electroplating hanger, stop pressing the second end of the clamping member 210. The reset member 230 drives the second end of the clamping member 210 to reset. At this time, as the clamping member 210 rotates around the bearing seat, the limiting member 220 abuts against the support rod 130 again, so as to realize the limiting connection between the upper crossbeam assembly 110 and the support rod 130.

[0039] Further, the reset member 230 is set as a spring. When pressing the second end of the clamping member 210, the spring is compressed. When no longer pressing the second end of the clamping member 210, the spring no longer receives pressure and starts to rebound automatically. During the process of automatic rebound, it drives the clamping member 210 to rotate around the bearing seat to realize the abutting limit between the limiting member 220 and the support rod 130. Positioning pins (not shown in the figure) are arranged on both the second end of the clamping member 210 and the outer wall of the sleeve 112. Both ends of the spring are respectively sleeved on the two positioning pins. During the compression and rebound process of the spring, the two positioning pins cooperate with each other to guide the spring and make the spring move along a predetermined route. After the spring is reset, the two positioning pins cooperate with each other to position the spring and prevent the spring from detaching between the clamping member 210 and the sleeve 112, so as to facilitate the next use of the limiting component 200.

[0040] In some other embodiments, the reset member 230 can also be set as a torsion spring. The torsion spring is sleeved on the rotating shaft of the bearing seat, and the two torsion shafts of the torsion spring respectively abut against the outer wall of the sleeve 112 and the second end of the clamping member 210.

[0041] Preferably, a plurality of first limiting teeth 131 are provided at the first end of the support rod 130. The plurality of first limiting teeth 131 are evenly spaced along the axial direction of the support rod 130. A second limiting tooth is provided at the end of the limiting member 220 facing away from the clamping member 210. The second limiting tooth is in limiting connection with the first limiting tooth 131 to further improve the stability of the limiting assembly 200 and the support rod 130 after the limiting connection, thereby improving the stability of the relative position of the upper crossbeam assembly 110 and the lower crossbeam assembly 120. In addition, by setting the distance between adjacent first limiting teeth 131, the accuracy of adjusting the relative position of the upper crossbeam assembly 110 and the lower crossbeam assembly 120 can be improved.

[0042] In some other embodiments, the limiting assembly 200 includes a positioning rod. A plurality of positioning holes are provided at the first end of the support rod 130 at intervals along its axial direction. The positioning rod can pass through the corresponding avoidance hole 101 and be inserted into the positioning hole. When it is necessary to adjust the relative position of the upper crossbeam assembly 110 and the lower crossbeam assembly 120, the positioning rod is pulled out from the current positioning hole, and the position of the upper crossbeam assembly 110 in the height direction can be adjusted. After the upper crossbeam assembly 110 is adjusted to the target position, the positioning rod is inserted into the target positioning hole to limit the upper crossbeam assembly 110 at the current position.

[0043] Alternatively, the limiting assembly 200 includes a threaded rod. The avoidance hole 101 is provided as a threaded hole. When it is necessary to adjust the relative position of the upper crossbeam assembly 110 and the lower crossbeam assembly 120, the threaded rod is loosened to adjust the position of the upper crossbeam assembly 110 in the height direction. After the upper crossbeam assembly 110 is adjusted to the target position, the threaded rod is tightened so that the threaded rod abuts against the support rod 130, thereby limiting the upper crossbeam assembly 110 at the current position.

[0044] Preferably, the lower crossbeam assembly 120 includes a lower fixing plate 121, support feet 122 and a plurality of connecting members. The support feet 122 are connected to the lower fixing plate 121 through the plurality of connecting members, and the plurality of connecting members are arranged in a mutually staggered manner.

[0045] When pushing the PCB board electroplating hanger, the support feet 122 are slidably connected to the track chute in the electroplating basket so that the PCB board electroplating hanger is pushed along a predetermined route. In this process, by arranging the plurality of connecting members in a mutually staggered manner, the relative positions of the support feet 122 and the lower fixing plate 121 are restricted in both the height direction and the width direction of the conductive frame 100. Therefore, during the process of pushing the PCB board electroplating hanger, the situation of the support feet 122 twisting and shifting can be reduced, thereby reducing the situation of the PCB board electroplating hanger colliding due to positioning errors, and further avoiding the situation of the PCB board being torn and damaged.

[0046] Further, the plurality of connecting members are provided as limiting bosses and two connecting columns 123, and the lower fixing plate 121 is provided with a receiving groove 1211 extending in the horizontal direction; the two connecting columns 123 are connected between the lower fixing plate 121 and the supporting feet 122 in the height direction, and the limiting boss is connected to the receiving groove 1211 in a limiting manner.

[0047] Specifically combined with Figure 6 As shown, the two connecting columns 123 are respectively located on both sides of the receiving groove 1211, and the midline of the receiving groove 1211 and the center connection line of the two connecting columns 123 are in a "cross" shape; when installing the supporting feet 122, first limit and connect the limiting boss to the receiving groove 1211 for positioning, and then connect the two connecting columns 123. The limiting boss and the two connecting columns 123 cooperate with each other to further improve the connection strength and connection stability between the supporting feet 122 and the lower fixing plate 121.

[0048] Preferably, the conductive frame 100 further includes an opening and closing assembly. The upper crossbeam assembly 110 and the lower crossbeam assembly 120 are both movably connected to the support rods 130 through the opening and closing assembly, so that the two support rods 130 can approach or deviate from each other in the left-right direction. By changing the distance between the two support rods 130 and changing the overall width of the PCB plating hanger, different-width PCB boards can be clamped for electroplating; the two relatively movably arranged support rods 130 cooperate with the movably arranged upper crossbeam assembly 110, and different specifications of PCB boards can be clamped, thereby further improving the versatility of the PCB plating hanger.

[0049] Further, the opening and closing assembly includes an opening and closing member 141 and an opening and closing plate 142. The opening and closing member 141 is arranged on the corresponding crossbeam, and a guiding channel is arranged on the opening and closing member 141. The opening and closing plate 142 is horizontally arranged, and the first end of the opening and closing plate 142 is connected to the corresponding support rod 130, and the other end is slidably connected to the corresponding guiding channel.

[0050] The opening and closing assembly arranged on the upper crossbeam assembly 110 is arranged as follows: the opening and closing member 141 is arranged on the upper fixing plate 111, one end of the opening and closing plate 142 is fixedly arranged on the corresponding sleeve 112, and the other end is slidably arranged in the corresponding guiding channel, ensuring that the upper crossbeam assembly 110 can simultaneously adjust the width and height. The opening and closing assembly arranged on the lower crossbeam assembly 120 is arranged as follows: the opening and closing member 141 is arranged on the lower fixing plate 121, one end of the opening and closing plate 142 is fixedly arranged on the second end of the corresponding support rod 130, and the other end is slidably arranged in the corresponding guiding channel. By changing the relative position between the opening and closing plate 142 and the corresponding guiding channel, the distance between the two support rods 130 is changed, thereby changing the overall width of the PCB plating hanger.

[0051] Taking one of the opening and closing members 141 as an example, the width of the guiding channel is greater than the thickness of the opening and closing plate 142 so as to slidably connect the opening and closing plate 142 to the guiding channel; a positioning groove 1411 communicating with the guiding channel is provided on the side wall of the guiding channel, and the positioning member 143 is connected to the positioning groove 1411 through a positioning spring 144 and abuts against the corresponding opening and closing plate 142; when it is necessary to adjust the width of the PCB electroplating hanger, the opening and closing plate 142 is pressed so that the positioning spring 144 is compressed. At this time, an avoidance position is left in the guiding channel to facilitate the sliding of the opening and closing plate 142 in the guiding channel; after the position adjustment is completed, the opening and closing plate 142 is no longer pressed, and the spring no longer receives an external force and starts to rebound autonomously, thereby driving the positioning member 143 to move towards the inside of the guiding channel so that the positioning member 143 presses the opening and closing plate 142 tightly in the guiding channel, thereby preventing the opening and closing plate 142 from slipping out of the guiding channel to ensure the structural stability after the width of the PCB electroplating hanger.

[0052] In addition, in order to further improve the structural stability after adjusting the width of the PCB electroplating hanger, a plurality of opening and closing members 141 are arranged at intervals along the width direction of the PCB electroplating hanger on both the upper fixing plate 121 and the lower fixing plate 121.

[0053] Preferably, a plurality of fixing clips 102 are arranged at intervals along the width direction on both the upper crossbeam assembly 110 and the lower crossbeam assembly 120. The plurality of fixing frames arranged on the upper crossbeam assembly 110 and the lower crossbeam assembly 120 cooperate with each other to clamp the PCB. At least two auxiliary clips 132 are arranged on the support rod 130 corresponding to the upper crossbeam assembly 110 and the lower crossbeam assembly 120. Thus, no matter how the width of the PCB electroplating hanger changes, it can be ensured that when the PCB is connected to the PCB electroplating hanger, the auxiliary clips 132 clamp the two side edges of the PCB in the width direction, thereby further improving the hanging stability of the PCB.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
