Description

Technical Field

[0001] The invention relates to the technical field of connector automatic manufacturing, and in particular to a cam-type cutting and plastic-inserting integrated machine. Background Art

[0002] Connectors usually consist of two parts, plastic parts and conductive terminals. During molding, the conductive terminals need to be inserted into the plastic, especially small terminal cutting and insertion equipment. In situations where there is limited space around the injection molding machine and other situations, a series of tasks such as automated clamping, cutting, and plugging need to be realized.

[0003] At present, the cutting of pins mostly uses the cylinder to act as a cutter, clamping the workpiece and other methods, such as cylinder direct cutting of terminals. Although these solutions are effective, multiple mechanisms act separately, and the various actions are combined together through the electronic control program. The production cycle of a single product is long, which increases the debugging time in the later stage.

[0004] Therefore, a cam cutting pin insertion machine and a terminal cutting and insertion method disclosed in Chinese patent CN116598865B have been developed, in which the first cam, the second cam, the third cam and the fourth cam are driven by a rotating shaft to respectively push the forward moving component, the ejection component and a pair of clamping and cutting components to cooperate with each other to complete the work of cutting and inserting the terminals. However, since the position of the forward moving component is too protruding, the distance between the forward moving component and the cam becomes larger, that is, the stroke of the cam becomes larger, which in turn affects its plug-in efficiency and occupies the limited space of other equipment. Secondly, the position of the forward moving component also interferes with the ejection component, and an additional cam is required to control the ejection component to pass through the forward moving component to eject the material. Its complex structure affects efficiency and has a high probability of failure.

[0005] Therefore, it is necessary to develop a cam-type cutting and plastic-inserting integrated machine to solve the above problems. Summary of the invention

The pushing member 223 is a shaft body, one end of which is fixedly connected to the follower body 221, and the other end extends vertically downward. When the transmission plate 212 rotates, the clamping shaft 222 moves along the movement trajectory of the first clamping cam 21. At this time, the follower body 221 rotates around the fixed shaft 224 to move the pushing member 223 in the opposite direction.

[0027] The first sliding assembly 23 includes a sliding body 231, a stopper 232 arranged at one end of the sliding body 231, and a first clamping claw 233 arranged at the other end of the sliding body 231.

When the first clamp 233 and the second clamp 34 clamp a single material, as they continue to move toward the second clamping module 3, the movable knife 236 and the fixed tool 5 cut the connection between the material strip and the material.

[0036] Please see Figure 1 In another embodiment, a first feeding device 6 and a second feeding device 7 are installed on the outer sides of the first clamping module 2 and the second clamping module 3. The first feeding device 6 includes a vertical feeding channel 61 and a vertical feeding drive 62. The vertical feeding channels 61 are a pair, which are respectively located above and below the first clamping module 2 and the second clamping module 3. The material belt with the material is discharged from the vertical feeding channel 61 located above, passes between the first clamping module 2 and the second clamping module 3, and enters the vertical feeding channel 61 located below.

The gear teeth can extend into the positioning holes of the material belt to drive the material belt to move. Preferably, a vertical plate 64 is installed at the end of the vertical feed channel 61 located above. One end of the vertical plate 64 is fixedly connected to the vertical feed channel 61, and the other end extends vertically downward to one side of the fixed tool 5. The material belt is located between the fixed tool 5 and the vertical plate 64 to facilitate cutting.

[0039] The first feeding device 6 and the second feeding device 7 are in a vertical relationship. The first feeding device 6 is used for conveying the material belt, and the second feeding device 7 is used for conveying the plastic parts.

[0040] When the cam-type cutting and inserting integrated machine of the present invention is used, the first feeding device 6 conveys the material belt to a predetermined position, the second feeding device 7 conveys the plastic part to a predetermined position, the first clamping cam 21 rotates, and the clamping shaft 222 moves along the motion trajectory of the first clamping cam 21. At this time, the follower body 221 rotates around the fixed shaft 224, so that the pusher 223 moves in the opposite direction, pushing the stopper 232, and the sliding body 231 moves toward the material belt direction through the slider 234. The first clamping claw 233 drives the moving knife 236 to move synchronously, and the second clamping claw 233 drives the moving knife 236 to move synchronously. The second clamping jaw 34 at the end of the holding module 3 moves toward the material belt, the first clamping jaw 233 and the second clamping jaw 34 clamp a single material on the material belt, and then continue to move toward the second clamping module 3, the movable knife 236 and the fixed knife 5 cut the connection between the material belt and the material, the insertion cam 41 rotates, and the second front and rear sliding member 43 drives the first clamping jaw 233 and the second clamping jaw 34 located on the moving platform 431 to move toward the plastic part.
