[0035] The technical scheme of the utility model adopts limiting assembly 3 including at least two movable clamping arms 31, and the limiting assembly 3 has opening state and locking state, when the connecting frame 2 does not need the limiting of limiting assembly 3, the limiting assembly 3 is in the opening state, so as to facilitate the displacement of connecting frame 2 on support frame 1;When the connecting frame 2 needs the limiting of limiting assembly 3, the limiting assembly 3 is in the locking state, and each clamping arm 31 cooperates to clamp and limit the connecting frame 2, and the connecting frame 2 realizes zero-gap clamping through each clamping arm 31 to completely fix the connecting frame 2, so as to replace the mode that the existing positioning block compresses the connecting frame 2 for a long time, so as to avoid the deformation of the connecting frame 2.

[0036] In the embodiment, the support frame 1 is used to support the connecting frame 2 and the limiting assembly 3.

The center of the support frame 1 along the length direction of the support frame 1 can have a clamping station used to clamp the connecting frame 2 so that the connecting frame 2 is clamped and limited when moving to the clamping station. The limiting assembly 3 is arranged at the clamping station and below the connecting frame 2. The user can control the limiting assembly 3 to move each clamping arm 31 to a avoiding position available for the connecting frame 2 to pass through so that the limiting assembly 3 is in the open state to facilitate the movement of the connecting frame 2. The user can control the connecting frame 2 to move to the clamping station and then control each clamping arm 31 to gradually move towards the connecting frame 2 from the avoiding position so that each clamping arm 31 abuts against the side wall and the top wall of the connecting frame 2 to clamp and limit the connecting frame 2 by each clamping arm 31, thereby improving the accuracy of clamping and limiting the connecting frame 2 by the limiting assembly 3, making different PCBs on different hangers be located at the clamping station, ensuring the uniformity of electroplating of the whole batch of PCBs, and thereby improving the yield of PCB electroplating.

[0042] In the embodiment, the first hook part 3114 is arranged to be bent relative to the first abutting part 3113, and the second hook part 3124 is arranged to be bent relative to the second abutting part 3123, so as to increase the contact area of the first clamping part 3112 and the second clamping part 3122 with the connecting frame 2 respectively, so that the first clamping part 3112 and the second clamping part 3122 can clamp and limit the connecting frame 2 more stably. In order to further limit the connecting frame 2, when the first clamping part 3112 and the second clamping part 3122 are in the locked state, the first clamping part 3112 and the second clamping part 3122 abut against the opposite two side walls of the connecting frame 2 respectively, so that the first clamping part 3112 and the second clamping part 3122 limit the movement of the connecting frame 2 along the extension direction of the supporting frame 1, and the first hook part 3114 and the second hook part 3124 abut against the top wall of the connecting frame 2, so that the first clamping part 3112 and the second clamping part 3122 cooperate with the supporting frame 1 to limit the lifting of the connecting frame 2.

[0044] In the embodiment, in order to further slow down the collision force when the first abutting portion 3113, the first hook portion 3114, the second abutting portion 3123 and the second hook portion 3124 respectively abut against the connecting frame 2, the end surface of the first abutting portion 3113 and the first hook portion 3114 respectively contacting the connecting frame 2 is provided with a first flexible member, and the end surface of the second abutting portion 3123 and the second hook portion 3124 respectively contacting the connecting frame 2 is provided with a second flexible member. The first flexible member and the second flexible member can be a rubber pad or a sponge pad or other flexible material buffer structure.

The first clamping portion 3112 and the second clamping portion 3122 are respectively adjusted in size by rotating relative to the connecting plate 33 to clamp and limit the connecting frame 2 more stably. When the first clamping portion 3112 and the second clamping portion 3122 are in the locked state, the size of the clamping space is adapted to the outer diameter size of the connecting frame 2 along the first direction, so that the first clamping portion 3112 and the second clamping portion 3122 are clamped without gap, thereby replacing the existing positioning block by extruding the connecting frame 2 into the limiting groove, thereby reducing the deformation of the connecting frame 2.

[0047] In the embodiment, due to the position error when the connecting frame 2 moves to the clamping station, the connecting frame 2 is offset to the side close to or away from the first clamping portion 3112 relative to the clamping station. In the process of gradually approaching and abutting against the connecting frame 2, one of the first clamping portion 3112 or the second clamping portion 3122 will abut against the connecting frame 2 first, and provide a pushing force to the connecting frame 2 to move to the side away from the offset direction, thereby correcting the position error of the connecting frame 2, thereby improving the accuracy of the connecting frame 2 moving to the clamping station.
