Description

Technical Field

[0001] This utility model relates to the technical field of flexible circuit board testing shielding boxes, and specifically to a flexible circuit board testing device with a shielding mechanism. Background Technology

[0002] Currently, in flexible circuit board testing equipment, two test positions and shielding boxes are typically placed on both sides. To improve testing efficiency, multiple test positions and corresponding shielding boxes are usually added to the testing equipment. Furthermore, to facilitate loading and unloading by robotic arms, placing multiple test positions and shielding boxes on one side reduces the robotic arm's movement path and improves its operational efficiency. However, most shielding boxes are currently independently driven, with separate drive cylinders and other components between two upper and lower shielding boxes for opening and closing. When multiple test positions are close together on one side, the drive cylinders and components are mostly located on the outside of the shielding box, resulting in a significant waste of space and making it inconvenient for multiple test positions to be closely aligned. Additionally, multiple drive cylinders increase the production cost of the testing equipment. Utility Model Content

[0003] The purpose of this invention is to address the problem that when multiple test positions are placed close together on one side, the drive cylinders and components are mostly located on the outside of the shielding box, which results in a large waste of space occupied by multiple drive cylinders, making it inconvenient for multiple test positions to be placed close together. At the same time, multiple drive cylinders also increase the production cost of the test device. This invention provides a flexible circuit board test device with a shielding mechanism.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution: A flexible circuit board testing device with a shielding mechanism includes two upper shielding boxes and two lower shielding boxes, which are arranged correspondingly to each other. Connecting side plates are fixedly installed on the side walls of both upper shielding boxes, and connecting plates are fixedly installed on the connecting side plates. A conductive pipe is fixedly installed on the side wall of one of the lower shielding boxes, and a conveying pipe is fixedly installed on the side wall of the other lower shielding box. A pipeline control mechanism is provided between the conveying pipe and the conductive pipe. A side connecting box is provided on one side of the lower shielding box near the conveying pipe, and a branch pipe is fixedly installed on the side wall of the side connecting box. One end of the branch pipe is fixedly installed on the conveying pipe, and a second electrically controlled valve is provided on the branch pipe. A pressure conveying mechanism is provided on the side wall of the lower shielding box near the conveying pipe, and the pressure conveying mechanism is connected to the conveying pipe. A pressure-bearing lifting mechanism is fixedly installed on the side walls of both the conductive pipe and the side connecting box, and the pressure-bearing lifting mechanism is fixedly installed on two connecting plates respectively.

[0005] Preferably, the pipeline control mechanism includes a connecting pipe, one end of which is fixedly installed on the conducting pipe and the other end of which is fixedly installed on the conveying pipe, and an electrically controlled valve is provided on the side wall of the connecting pipe.

[0006] Preferably, the pressure conveying mechanism includes a liquid storage cylinder, which is fixedly installed on the lower shielding box and connected to the conveying pipe. A pusher plate is slidably arranged inside the liquid storage cylinder. A drive cylinder is fixedly installed on the side wall of the lower shielding box, and one end of the drive cylinder is fixedly installed on the pusher plate. A control plate is fixedly installed on the side wall of the liquid storage cylinder, and the control plate and the drive cylinder are electrically connected.

[0007] Preferably, the pressure-lifting mechanism includes a guide slide, the bottom of which has a liquid inlet hole, a piston plate is slidably installed inside the guide slide, and a push rod is fixedly installed on one side of the piston plate, with one end of the push rod fixedly installed on a connecting plate.

[0008] Preferably, mounting holes are provided on both the connecting side plate and the side wall of the upper shielding box, and a partition tube is fixedly installed in both mounting holes. A spring hinge is fixedly installed on one end of the partition tube inside the upper shielding box, and a sealing plate is fixedly installed on one end of the spring hinge. The sealing plate is hinged to the partition tube by the spring hinge, and a miniature fan is fixedly installed inside the partition tube.

[0009] Preferably, an L-shaped plate is fixedly installed on the side wall of the connecting side plate, one end of the L-shaped plate is fixedly installed on the connecting side plate, and one side of the L-shaped plate abuts against the upper end of the upper shielding box. Positioning holes are provided on both the L-shaped plate and the side wall of the upper shielding box, and a support sleeve is fixedly installed in the positioning hole. The bottom of the support sleeve is transparent, and a monitoring camera is fixedly installed on the bottom of the support sleeve. A protective ring is screwed onto the support sleeve.

[0010] The beneficial effects of this utility model are as follows: 1. In this utility model, by using components such as a control board, a drive cylinder, and a first electrically controlled valve, when it is desired to open and close the upper and lower shielding boxes located at the control board position, the first electrically controlled valve is closed via the control board. Then, the drive cylinder pushes the hydraulic oil in the reservoir into the side connecting box, and then through the side connecting box into the guide slide installed thereon. The push rod then drives the upper shielding box to open. By operating the drive cylinder in the reverse direction, the upper shielding box can be moved down to close. Similarly, the operation of the other shielding box can be achieved by opening the first electrically controlled valve and then closing the second electrically controlled valve. In this way, shielding boxes on multiple test positions can be combined, which not only saves the number of drive cylinders and components, thus saving space, but also reduces production costs.

[0011] 2. In this utility model, the miniature fan can be started after the test is completed, thereby forming an airflow from the outside air to push open the sealing plate. This can accelerate the airflow between the two shielding boxes, thereby accelerating the heat dissipation effect. Furthermore, the monitoring camera can easily transmit the environment inside the shielding box to the outside in real time, so that test problems can be detected and maintained in a timely manner.

The protective ring 9 facilitates the passage of wire harnesses, and the monitoring camera 20 can easily transmit the environment inside the shielding box to the outside in real time, so that test problems can be detected and maintained in a timely manner.

[0020] A connecting plate 6 is fixedly installed on the connecting side plate 3. A conduction pipe 11 is fixedly installed on the side wall of one of the lower shielding boxes 2, and a delivery pipe 16 is fixedly installed on the side wall of the other lower shielding box 2. A pipeline control mechanism is provided between the delivery pipe 16 and the conduction pipe 11. The pipeline control mechanism includes a connecting pipe 12. One end of the connecting pipe 12 is fixedly installed on the conduction pipe 11, and the other end of the connecting pipe 12 is fixedly installed on the delivery pipe 16. A first electrically controlled valve 13 is provided on the side wall of the connecting pipe 12. The two shielding mechanisms can be operated separately by the first electrically controlled valve 13, so as to achieve mutual non-interference.

[0021] A side connection box 15 is provided on one side of the conveying pipe 16 on the lower shielding box 2, and a branch pipe 14 is fixedly installed on the side wall of the side connection box 15. One end of the branch pipe 14 is fixedly installed on the conveying pipe 16, and a second electrically controlled valve 24 is provided on the branch pipe 14. A pressure conveying mechanism is provided on the side wall of the lower shielding box 2 on one side of the conveying pipe 16.

One guide slide cylinder 701 is connected to the transmission pipe 11, and the other guide slide cylinder 701 is connected to the side connection box 15.

[0023] In summary: When the control panel 18 is to be operated to change the position of the upper shielding box 1 and the lower shielding box 2, the control panel 18 closes the first solenoid valve 13 and opens the second solenoid valve 24. Then, the drive cylinder 19 is activated, which pushes the hydraulic oil in the reservoir 17 into the side connection box 15, and then through the side connection box 15 into the guide slide 701 installed thereon. The hydraulic oil then pushes the internal piston plate 702 and push rod 704 to move. In this way, the push rod 704 drives the upper shielding box 1 to move upward and open. The reverse operation of the drive cylinder 19 causes the hydraulic oil to be returned to the reservoir. Inside cylinder 17, the upper shielding box 1 can be moved down and closed. To control another set of shielding boxes, the control board 18 can be used to open the first electric control valve 13 and then close the second electric control valve 24, and then the drive cylinder 19 can be started to move, thereby enabling the operation of the other shielding box. In this way, multiple shielding boxes at multiple test positions can be opened and closed. When the upper shielding box 1 is opened after the test, the micro fan 5 can be started by the control board 18, so that the micro fan 5 can form an airflow from the outside air to push open the sealing plate 23, which can accelerate the airflow between the upper shielding box 1 and the lower shielding box 2, thereby accelerating heat dissipation. During the test, the monitoring camera 20 can transmit the image, which can help the staff find problems during maintenance and repair.
