When the electromagnet 6 is powered on, it is magnetically attracted to the magnetic block 5.

[0020] In the above structure, the steel belt 3 can be driven by the front transmission wheel 12 and the rear transmission wheel 13 to circulate. A first slide rail 4 is provided on one side of the frame 1, and the hanger 2 can be slidably hung on the first slide rail 4. At the same time, the magnetic block 5 is evenly distributed on the edge of one side of the steel belt 3. The two electromagnets 6 on one side of the hanger 2 are aligned with the magnetic block 5. When the hanger 2 moves onto the first slide rail 4, the two electromagnets 6 are energized and generate magnetic force. The electromagnet 6 and the magnetic block 5 are magnetically attracted to each other, and a sufficiently strong magnetic force is used to drive the hanger 2 to move forward along the first slide rail 4. Compared with the prior art method of using chains and buckles for transmission, the utility model can avoid adverse conditions such as loosening and tooth jumping of the transmission mechanism, thereby maintaining smooth movement of the hanger 2 and improving the translational conveying accuracy of the hanger 2.

[0021] To realize the power-on function of the electromagnet 6, please refer to Figure 2 and Figure 3 A side frame 10 is fixed to the outside of the frame 1. Two parallel conductive rails 11 are fixed to the side frame 10. Two conductive contacts 7 are fixed to the side of the hanger 2 away from the steel belt 3. The two conductive contacts 7 are electrically connected to the two ends of the electromagnet 6 respectively. The two conductive contacts 7 are respectively arranged on the two conductive rails 11, and the conductive contacts 7 are electrically contacted with the conductive rails 11. In the above structure, the two conductive contacts 7 can be electrically connected to the electromagnet 6 via a cable. Because the two conductive contacts 7 maintain electrical contact with the two conductive rails 11, power can be supplied to the electromagnet 6 via the two conductive rails 11 and the two conductive contacts 7, thereby causing the electromagnet 6 to generate magnetism.

[0022] Regarding the preferred method for fixing the electromagnet 6 and the conductive contact 7, in this embodiment, a first support arm 20 and a second support arm 21 are respectively provided on either side of the hanger 2, and the electromagnet 6 and the conductive contact 7 are respectively mounted on the first support arm 20 and the second support arm 21. By providing the first support arm 20 and the second support arm 21 on either side of the hanger 2, this embodiment allows the electromagnet 6 and the conductive contact 7 to extend as far as possible toward both sides of the hanger 2, thereby preventing positional interference between the electromagnet 6 and the conductive contact 7 and other mechanisms on the frame 1.

[0023] To better connect and slide with the first slide rail 4, in this embodiment, the hanger 2 includes a slide groove 29, which is engaged and slides with the first slide rail 4. Furthermore, the hanger 2 is Z-shaped, and a laterally extending mounting arm 22 is fixed to the lower end of the hanger 2.

In actual application, the front drive wheel 12 and / or the rear drive wheel 13 can be driven by a preset motor drive mechanism.

[0025] Combine Figure 1 、 Figure 4 and Figure 5 As shown, the front and rear sides of the frame 1 are both provided with a reversing bracket 8, a vertically arranged reversing motor 80 is fixed on the reversing bracket 8, a reversing turntable 81 is provided at the top of the driving shaft of the reversing motor 80, and a reversing rail 82 for hanging the pylon 2 is provided on one side of the reversing turntable 81, a second slide rail 9 and a reflux drive mechanism 14 for driving the pylon 2 to move horizontally on the second slide rail 9 are provided on the side of the frame 1 facing away from the first slide rail 4, and the reversing load mechanism 14 on the two reversing brackets 8 is provided. The rails 82 are aligned with the first slide rail 4 and the second slide rail 9 respectively, wherein: when the hanger 2 slides from the first slide rail 4 into the reversing rail 82, the reversing motor 80 drives the reversing turntable 81 to rotate 180° so that the reversing rail 82 is aligned with the second slide rail 9, and the hanger 2 is pushed from the reversing rail 82 to the second slide rail 9 by a preset pushing mechanism, and then the reflux drive mechanism 14 drives the hanger 2 to move horizontally on the second slide rail 9.

[0026] When the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position, the cam 82 is in the forward position and the cam 82 is in the forward position,

[0027] Based on the above structural principle, the utility model can maintain the smoothness and non-shaking movement of the hanger during the process of entering the electroplating cylinder. At the same time, there will be no loosening or stretching of the steel belt during the transmission process, and the electromagnet on the hanger will quickly attract the magnetic block on the steel belt to ensure that the hanger does not jump teeth, and the distance between the hangers is constant, thereby ensuring that the uniformity of the electroplating layer in the PCB board electroplating production process meets the process requirements.
