Description

Technical Field

[0001] The utility model relates to the technical field of terminal processing, and more specifically to a terminal deburring machine. Background Art

[0002] The terminal block is used to connect the terminal to the wire. It is processed with screw holes or through holes. During the processing, certain burrs will inevitably be generated. Therefore, the terminal block needs to be deburred. The existing technology mostly adopts the method of installing many terminals in a drum and rotating the drum. The terminals are shaken and knocked against each other to achieve the deburring operation. However, there is a situation where the terminals collide with each other and are damaged, resulting in a low terminal yield rate. A small part of the existing technology will manually place the terminals one by one on the fixture and use a deburring device to scrape them. During this period, the terminal needs to be manually flipped to remove the burrs on the other side of the terminal. The operation is complicated and inefficient. At the same time, in order to avoid the terminal being skewed when placed on a plane and affecting the deburring operation, workers usually clamp one end of the terminal and leave the other end hanging in the air. In this way, when the deburring device exerts downward pressure on the terminal, the terminal is easy to bend and deform, which affects the actual use. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a terminal deburring machine which has high deburring efficiency and can ensure a stable terminal structure.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a terminal deburring machine, comprising a turntable that can rotate relative to a workbench, a plurality of workstations that are distributed in a circle around the rotation center of the turntable and are all positioned on the turntable, a loading assembly for loading terminals, a deburring assembly for scraping burrs off the surface of the terminal, and an arc-shaped carrier that is coaxial with the turntable and located outside the turntable, the plurality of workstations comprising a loading station corresponding to the loading assembly, a scraping station corresponding to the deburring assembly, and a guiding station that is adjacent to the scraping station and drives the terminal to be under the deburring assembly, one end of the arc-shaped carrier is located under the deburring assembly and corresponds to the scraping station, the other end of the arc-shaped carrier is provided with a chamfered surface and is adjacent to the guiding station, and in the process of the guiding station moving the terminal to the scraping station, the terminal slides successively on the chamfered surface and the upper surface of the arc-shaped carrier.

[0005] As a further improvement of the utility model, the loading assembly includes a straight vibrator positioned on the workbench, a material channel positioned above the straight vibrator, a vibration disk connected to one end of the material channel, a clamping cylinder located on one side of the material channel and used to clamp the terminal, a material moving cylinder that drives the clamping cylinder to move along the length direction of the material channel, and an advance and retreat cylinder that drives the material moving cylinder to move along the width direction of the material channel. A material distribution port for the terminals to enter and exit is provided on the side wall of the material channel adjacent to the material moving cylinder, and the material distribution port is located at the end of the material channel that is not connected to the vibration disk.

[0006] As a further improvement of the utility model, a plurality of the workstations are each provided with a pair of clamping jaws for clamping the terminal, and the facing surfaces of the paired clamping jaws are each provided with a V-shaped groove for partially accommodating the terminal.

[0007] The beneficial effects of the utility model are as follows: the burrs on the lower surface of the terminal are erased by moving the terminal on the arc carrier. Compared with the prior art, such a design can achieve burr removal on both sides of the terminal without flipping the terminal, thereby improving the efficiency of burr removal; the design of the chamfered surface can preliminarily flatten the burrs on the lower surface of the terminal so that the terminal can be smoothly moved to the upper surface of the arc carrier and deburred; the arc carrier provides support for the terminal, which can indirectly improve the bending resistance of the terminal compared to the prior art design of suspending the terminal, thereby ensuring the stability of the terminal structure.

Then, the thickness of the arc-shaped carrier 5 in the rotation direction of the turntable 1 changes from small to large and then remains unchanged.
