Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a testing device with a cover-opening safety device. Background Technology

[0002] A testing mechanism for PCBA male connectors includes a frame, an upper loading board module slidably connected to the frame, an upper pressure plate module located on top of the frame, a test module located on top of the upper pressure plate module and pulsatorically connected to it, and a lower pin block module located below the upper pressure plate module. The upper loading board module, upper pressure plate module, test module, and lower pin block module are arranged in a cooperative manner. The upper loading board module has a placement slot. The test module has a vertically arranged test head and a horizontally arranged pin header. The lower pin block module has probes and a circuit board electrically connected to the probes. However, this testing mechanism is located on the top cover of a chassis, resulting in a heavy load on the top cover, which contains many electrical components. During maintenance and repair, the top cover needs to be opened upwards, requiring personnel to reach into the chassis. If the top cover accidentally falls back, it could crush the personnel's hands, causing a serious accident. Utility Model Content

[0003] The purpose of this invention is to provide a testing device with a high safety performance and a cover-opening safety device.

[0004] To achieve the above objectives, this utility model provides a testing device with a cover-opening safety device, comprising a base box, a top cover, a testing mechanism, a cover-opening drive device, and a cover-opening safety device. The top cover is mounted on the base box, and the testing mechanism is mounted on the top cover. The testing mechanism includes a lower needle plate, an infeed / outfeed assembly, and a pressing assembly. The lower needle plate and the pressing assembly are vertically aligned. The infeed / outfeed assembly is movably mounted between the lower needle plate and the pressing assembly. The pressing assembly includes a pressure plate and a pressing drive device. The pressing drive device is mounted on the bottom wall of the top cover, and its driving end penetrates the top cover to drive the pressure plate to move up and down. The cover-opening drive device is mounted inside the base box, and its two ends are hinged to the top cover and the base box, respectively. The cover-opening drive device can drive the top cover to rotate up and down around one side. The cover-opening safety device is mounted inside the base box and includes a support block. The support block can be rotated upward and abuts against the top cover to restrict the top cover from closing.

[0005] As can be seen from the above scheme, by setting a testing mechanism on the top cover, it is convenient for staff to conduct relevant tests; by setting a cover opening drive device, the top cover is used to drive it to flip upward to open the bottom box; because the top cover is equipped with a testing mechanism, the load-bearing capacity of the top cover is relatively large. During maintenance and repair, in the event of an accident or operational error, the top cover will quickly flip downward. By setting a cover opening safety device to abut against the top cover, it is possible to prevent the top cover from falling back unexpectedly and causing accidental injury, which helps to improve its safety performance.

[0006] A further proposed solution is to have two opening drive devices, which are respectively located on both sides of the bottom box; a first connecting part is provided on both sides of the bottom wall of the top cover, and a second connecting part is provided on both side walls of the bottom box; the first end of the opening drive device is hinged to the first connecting part, and the second end of the opening drive device is hinged to the second connecting part.

[0007] A further solution is to offset the first connecting part and the second connecting part in the vertical direction, so that the opening drive device extends upward at an angle.

[0008] A further embodiment is that the opening safety device also includes a fixed base, a rotating shaft, and a rotating control component. The fixed base is set on the inner side wall of the base box, and an installation part is set between the two ends of the support block. The rotating control component is set on the first end of the rotating shaft, and the second end of the rotating shaft passes through the side wall of the base box and the fixed base and is connected to the installation part. The rotating control component can drive the rotating shaft to rotate, so as to drive the support block to flip up and down.

[0009] A further solution is to provide a first abutment and a second abutment at each end of the support block, with the first abutment abutting with the top cover; and a third abutment on the fixed base, with the second abutment abutting with the third abutment to limit the upward rotation angle of the support block.

[0010] A further embodiment is that the mounting base includes a first mounting plate and a second mounting plate. The first mounting plate is fixedly connected to the side wall of the base box, and the second mounting plate is connected to the first mounting plate. The second mounting plate is provided with a support surface for receiving the support block, and a third abutment part is provided at one end of the second mounting plate, and the third abutment part is perpendicular to the support surface.

[0011] As can be seen from the above scheme, in the closed state, the support block rests on the support surface to avoid the support block from contacting the top cover; in the open state, the support block flips upward until the third abutment part abuts against the second abutment part, at which time the support block can be used to support the top cover to prevent accidental closing.

[0012] A further design involves providing a clearance groove on one side of the top cover; the inlet / outlet assembly includes a movable frame, a carrier plate, a translation drive device, and a movable plate. The movable frame is slidably mounted on the top cover, the carrier plate is mounted on the movable frame, and the movable plate is mounted in the clearance groove and connected to the drive ends of the movable frame and the translation drive device, respectively. The translation drive device is mounted on the bottom wall of the top cover and drives the movable frame to move horizontally via the movable plate.

[0013] A further embodiment includes a fixed frame, a lifting frame, a pressure plate, and a lifting drive device. The fixed frame is mounted on the top cover, the lifting frame is slidably connected to the fixed frame, the pressure plate is mounted on the lifting frame, and the pressing drive device is mounted on the bottom wall of the top cover. The drive shaft of the pressing drive device passes upward through the top cover and connects to the lifting frame.

[0014] A further solution is to install adjustable spring latches on both sides of the bottom box and locking fasteners on both sides of the top cover, with the adjustable spring latches and locking fasteners being detachably connected.

[0015] A further option is that the test equipment with a cover-opening safety device also includes a protective cover, which is set on the top cover and located on the outside of the test mechanism. Attached Figure Description
