Description

Technical Field

[0001] It relates to the technical field of connector automated manufacturing, and particularly to a cam-type cutting and plastic inserting integrated machine. Background Art

[0002] A connector is usually composed of two parts, a plastic part and a conductive terminal. During molding, the conductive terminal needs to be inserted into the plastic. Especially for small terminal cutting and inserting equipment, in situations such as around an injection molding machine and other places with limited space, a series of operations such as automatic clamping, cutting, and inserting need to be achieved.

[0003] Currently, when cutting and inserting pins, a cylinder is mostly used to actuate the cutter and clamp the workpiece, such as directly cutting the terminal with a cylinder. Although these solutions are effective, multiple mechanisms act independently, and each action is combined through an electric control program. The production cycle of a single product is long, increasing the later debugging time.

[0004] Therefore, there appears a cam cutting and pin inserting machine and a terminal cutting and inserting method disclosed in Chinese Patent CN116598865B. The first cam, the second cam, the third cam, and the fourth cam are driven by a rotating shaft to respectively push the forward movement assembly, the ejecting assembly, and a pair of clamping and cutting assemblies to cooperate with each other to complete the work of cutting and inserting the terminal. However, due to the position of the forward movement assembly being too protruding, the distance between the forward movement assembly and the cam becomes larger, that is, the stroke of the cam increases accordingly, which in turn affects its inserting efficiency and occupies the limited space of other equipment. Secondly, the position of the forward movement assembly also interferes with the ejecting assembly, and an additional cam is required to control the ejecting assembly to pass through the forward movement assembly to eject the workpiece. Its complex structure affects the efficiency and has a relatively 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

[0015] Furthermore, limiting grooves are arranged on both sides of the moving platform. The limiting grooves are radially recessed from the lower surface of the moving platform, and fixing blocks are arranged below the limiting grooves. The fixing blocks are in a fixed state, and their tops extend into the limiting grooves.

[0016] Furthermore, the first front-back sliding member includes a front-back sliding main body part and a clamping part arranged at one end of the front-back sliding main body part. The push pin rod is arranged at the other end of the front-back sliding main body part. One end of the push pin rod is fixedly connected to the front-back sliding main body part, and the other end extends towards the first clamping module and the second clamping module.

[0017] Furthermore, the first clamping module includes a first follower assembly and a first sliding assembly that are clamped to the first clamping cam. The first follower assembly includes a follower main body, a clamping shaft installed at one end of the follower main body, and a pushing member installed at the other end of the follower main body.

The first feeding device 6 includes a vertical feeding channel 61 and a vertical feeding driving member 62. The number of the vertical feeding channels 61 is a pair, which are respectively located above and below the first clamping module 2 and the second clamping module 3. The strip with workpieces exits 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.

[0047] A gear 63 is installed at the end of the vertical feeding driving member 62. The gear 63 extends into the vertical feeding channel 61 located above, and its teeth can extend into the positioning holes of the strip to drive the strip to move. Preferably, a vertical plate 64 is installed at the end of the vertical feeding channel 61 located above. One end of the vertical plate 64 is fixedly connected to the vertical feeding channel 61, and the other end extends vertically downward to one side of the fixed cutter 5. The strip is located between the fixed cutter 5 and the vertical plate 64, which is convenient for cutting.

[0048] The second feeding device 7 includes a horizontal feeding channel 71. The horizontal feeding channel 71 extends horizontally from the first clamping module 2 to the second clamping module 3.

[0050] When the cam - type cutting and plastic - inserting integrated machine of the present invention is in use, the first feeding device 6 conveys the material belt to a predetermined position, and the second feeding device 7 conveys the plastic parts to a predetermined position. The first clamping cam 21 rotates, and the clamping shaft 222 moves along the movement track of the first clamping cam 21. At this time, the follower body 221 rotates around the fixed shaft 224, causing the pushing member 223 to move in the opposite direction, pushing the blocking block 232. The sliding body 231 moves towards the material belt direction through the slider 234, and the first clamping jaw 233 drives the moving knife 236 to move synchronously. At the same time, the second clamping jaw 34 at the end of the second clamping module 3 moves towards the material belt direction. The first clamping jaw 233 and the second clamping jaw 34 clamp a single workpiece on the material belt, and then continue to move towards the second clamping module 3. The moving knife 236 cuts the connection between the material belt and the workpiece with the fixed tool 5. The inserting cam 41 rotates, and the second front - and - back sliding member 43 drives the first clamping jaw 233 and the second clamping jaw 34 located on the moving platform 431 to move towards the plastic part direction.

[0051] The present invention is a cam - type cutting and plastic - inserting integrated machine, which has the characteristics of reducing the equipment failure rate, improving the production efficiency, and reducing the floor area of the equipment. By reducing the distance between the first front - and - back sliding member and the second front - and - back sliding member and the inserting cam, the stroke of the inserting cam is reduced, the insertion efficiency is improved, and the occupied space is optimized. At the same time, the fixed tool and the push - pin rod are exposed between the first clamping jaw and the second clamping jaw, reducing the probability of equipment failure.
