Description

Technical Field

[0001] The utility model relates to the field of electronic technology, in particular to a lifting and positioning circuit board for an electroplated sports car. Background Art

[0002] The SCP line is a graphic vertical electroplating equipment in the mSAP circuit board production process, and the intelligent electroplating sports car is an important part of electroplating. In the automatic production process, the sports car frame has the function of carrying the production board and fixing the production board without shifting. In order to meet the production needs, the sports car will lift, walk or stay in each slot on the frame on the line to complete the process required for the production board.

[0003] When a single sports car carries a production board to complete the entire electroplating process, the sports car frame needs to complete the lifting work dozens of times. In a full-load production environment, the frequency of use of a single sports car frame lifting and positioning circuit board will reach hundreds of times a day. The existing lifting and positioning circuit board is equipped with a deceleration sensor and a horizontally set stop sensor. The function of the deceleration sensor is that when the frame is about to be lifted to the specified height, the sports car main board receives the deceleration signal of the deceleration sensor and reduces the voltage supplied to the lifting motor, thereby achieving the purpose of decelerating the frame lifting, and then stops under the action of the signal of the stop sensor.

[0004] In actual applications, the deceleration control effect of the deceleration sensor on the frame is not ideal. Specifically, after receiving the deceleration signal, the mainboard decelerates the frame after a secondary conversion. Due to a certain time difference, the actual deceleration speed of the frame is faster than the theoretical deceleration speed. To overcome this defect, a lifting timeout alarm is set for the frame. The frame stops within the preset time and the production line works normally. When the frame lifting exceeds the preset time, an alarm will occur, causing the entire line to stop, affecting the production quality and progress of other production boards.

[0005] In addition, since there is only one horizontally set stop sensor with a small range, when the frame is close to the door frame, the impact force is large, causing the electronic components on the positioning circuit board to be damaged by vibration, resulting in failure of the frame lifting and stopping positioning, causing an alarm on the production line, resulting in the entire line being stopped, affecting the production quality and progress of other production boards.

[0006] In addition, since the SCP line is an electroplating device, the electroplating itself is in a weakly acidic working environment. Furthermore, the circuit board needs to be surface treated before electroplating to clean debris, dust and other foreign matter. It is inevitable to use chemical agents such as sulfuric acid. Therefore, the acidic volatile gas will be mixed with the air, reducing the service life of the deceleration sensor and the stop sensor. Utility Model Content

[0007] The purpose of the utility model is to provide a lifting and positioning circuit board for an electroplated sports car, which does not require a deceleration sensor, increases the sensing range of the stop signal, avoids collision between the frame lifting and the door frame, increases the service life of the sensor, and improves the stability of production.
