Description

Technical Field

[0001] This invention relates to the field of PIN pin testing equipment technology, and more specifically to a conveying device for PIN pin testing equipment. Background Technology

[0002] Pins are metallic materials used in connectors to transmit electricity or signals. More and more connectors use pins as signal transmitters. During connector production, pins are mainly inserted automatically by pinning machines. However, existing pinning machines cannot screen out pins within specifications 100%, and sometimes non-specification pins are mixed in. The detection of pins mainly relies on manual inspection, which has low inspection efficiency.

[0003] Chinese Patent CN218496021U discloses a PIN needle detection device, including a base, a cover fixedly mounted on the top of the base, a drive mechanism fixedly mounted on the rear side of the cover, a lifting plate fixedly connected to the bottom of the drive mechanism via a connecting block, and inserts fixedly mounted at equal intervals on the bottom of the lifting plate. A door control switch is fixedly mounted on the top of the inner cavity of each insert, and indicator lights are fixedly mounted at equal intervals on the front surface of the lifting plate. By setting up the drive mechanism, the lifting plate can be controlled to rise and fall. When the lifting plate descends under the control of the drive mechanism, the tip of a qualified PIN needle inserted into the top of the limit sleeve will insert into the inner cavity of the insert and abut against the door control switch. The door control switch will then turn off the indicator lights, indicating that the PIN needle is qualified. When the PIN needle is bent or too short and unqualified, the tip of the PIN needle will not insert into the inner cavity of the insert and abut against the door control switch, and the indicator light will remain on. The loosening locking assembly can move the support plate up and down to adjust the distance between the support plate and the lifting plate, allowing for the detection of PIN needles of different lengths.

[0004] The shortcomings of the existing solution are: the bottom of the lifting plate is fixed with sleeves at equal intervals, and the PIN pins are detected through the sleeves. The detection base is set to match the PIN pins with the sleeves at equal intervals, which limits the detection scenario and is not conducive to improving the detection efficiency of the PIN pins. Summary of the Invention

[0005] The purpose of this invention is to provide a conveying device for a PIN pin detection equipment, so as to solve the technical problem that the detection scenarios in the prior art are limited, which is not conducive to improving the detection efficiency of PIN pins.

One end of the spacer rod is fixedly connected to the equal-dividing connecting end, and the other end of the spacer rod abuts against the equal-dividing connecting end of the adjacent equal-dividing ring. A horizontally arranged connecting plate is fixedly connected to the side end face of each equal-dividing connecting end, and a connecting mechanism is provided between each adjacent connecting plate.

[0009] The conveying mechanism includes a conveying base, a conveying bottom plate fixedly connected to the upper end of the conveying base, a cylinder fixedly connected to the conveying bottom plate, a telescopic rod fixedly connected to the drive end of the cylinder, a docking sleeve rod fixedly connected to the telescopic rod, the docking sleeve rod being fitted into the docking hole on the docking block, a lifting frame fixedly connected to the conveying bottom plate, a conveying mounting plate fixedly connected to the lifting frame, a limit plate fixedly connected to the conveying mounting plate, and a limit groove for mounting PIN pins provided on the limit plate.

[0010] The conveyor belt has side frames at both ends and is fixedly installed on the side frames. The conveyor belt has several conveying mechanisms, and the evenly distributed rings on the slide bars of the conveying mechanism and the adjusting mechanism correspond one-to-one. The conveying base is set between the two side frames, and the conveyor belt is set on one side of the adjusting mechanism. The conveyor belt and the slide bars are set in parallel.

[0012] As a further aspect of the present invention: a drive shaft is coaxially fixedly connected to the drive end of the motor, and a gear is coaxially fixedly connected to the drive shaft, with the gear meshing with the rack.

[0013] As a further embodiment of the present invention: a traction connecting end is fixedly connected to the lower end of the traction ring, and a connecting rod two is fixedly connected between the traction connecting end and the equal-dividing connecting end of the nearest equal-dividing ring.

[0014] As a further aspect of the present invention: a fixed connecting end is fixedly connected to the lower end of the fixed ring, and a connecting rod is fixedly connected between the fixed connecting end and the equal-dividing connecting end of the nearest equal-dividing ring.

[0015] As a further aspect of the present invention, two mounting through holes are respectively provided on the connecting plate.

[0016] As a further embodiment of the present invention: the connecting mechanism includes an evenly distributed connecting rope, one end of which is fixedly connected to a first sleeve block, and an anti-detachment block is fixedly connected to the first sleeve block.

[0018] The beneficial effects of this invention are:

[0019] 1. In use, this invention uses a mechanical gripper to place the PIN pins one by one into the limiting grooves of the conveyor mechanism on the conveyor belt. With the obstruction of the baffle, several conveyor mechanisms are arranged on the conveyor belt. A spacer is provided between adjacent evenly distributed connecting ends. By setting the spacer, the distance between the several evenly distributed rings corresponds to the width of the conveyor mechanism, facilitating automatic docking of the docking sleeve rod with the docking hole on the docking block, thus improving the automation level of the device. When the docking sleeve rod docks with the docking hole, the motor is started to drive the gear to rotate. The gear meshes with the rack, allowing the traction ring to move autonomously along the slide bar. Several equal-dividing rings are pulled by the traction ring. Since there are connecting mechanisms between adjacent equal-dividing rings, the equal-dividing rings can be evenly distributed on the slide bar. Since the docking sleeve rod is connected to the docking hole, the equal-dividing rings can drive the conveying mechanism to be evenly distributed on the conveyor belt. This facilitates the simultaneous detection of PIN needles on the conveying mechanism by the evenly distributed inserts. When using this device, the detection device can be set up on the side frames on both sides of the conveyor belt. The conveyor belt can be a circulating conveyor belt. With the mechanical gripper in conjunction with the adjustment mechanism and the conveying mechanism, large-scale, high-efficiency, fully automatic detection of PIN needles can be achieved.

[0020] 2. In this invention, the first sleeve is installed in the mounting through hole of the connecting plate at one side of the evenly distributed connecting end, and the second sleeve is installed in the mounting through hole of the connecting plate at the other side of the evenly distributed connecting end. In use, the anti-detachment screw on the second sleeve is unscrewed, the second sleeve is passed through the mounting through hole of one side of the connecting plate, and the evenly distributed connecting rope is passed through the mounting through hole on that side and the second sleeve is installed in the mounting through hole on that side. Then the second sleeve is installed in the mounting through hole of the other side of the connecting plate, and the anti-detachment screw is screwed on to complete the installation of the connecting mechanism on the connecting plate. The anti-detachment screw facilitates the disassembly and assembly of the connecting mechanism. The connecting mechanism can be pre-customized with evenly distributed connecting ropes of different lengths, making the device easy to adapt to different models of testing equipment and improving the applicability and versatility of the device.

[0043] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios:

[0044] In use, a mechanical gripper places the PIN pins one by one into the limiting grooves 39 of the conveyor mechanism 3 on the conveyor belt 4. With the obstruction of the baffle, several conveyor mechanisms 3 are arranged on the conveyor belt 4. A spacer bar 119 is provided between two adjacent evenly spaced connecting ends 111. The spacer bar 119 ensures that the distance between several evenly spaced rings 18 corresponds to the width of the conveyor mechanism 3, facilitating automatic docking of the docking sleeve 35 with the docking hole 110 on the docking block 19, thus improving the automation level of the device.

Then, the second sleeve block 24 is fitted into the mounting through hole 121 of the connecting plate 120 on the other side. Finally, the anti-detachment screw 25 is screwed on to complete the installation of the connecting mechanism 2 on the connecting plate 120.
