Detailed Description

In order that the above-recited objects, features and advantages of the present application will become more readily apparent, a more particular description of the utility model briefly described above will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

In cutting a strip-like material (e.g., a solder strip, a film strip), it is generally necessary to provide a clamp feed mechanism and a traction mechanism on the front and rear sides of the cutting device, respectively. After each time the strip-shaped material is cut off, the end part of the strip-shaped material in the feeding direction is sent out of the cutting edge by the clamping feeding mechanism, so that the traction mechanism can conveniently draw the strip-shaped material out of a preset length, and the cutting device can cut off again. The manner in which the clamp feed mechanism is provided increases the cost and structural complexity of the apparatus.

To the above-mentioned technical problem that traditional cutting device exists, this application provides a banded material cutting device, adopts this banded material cutting device, need not to use again to press from both sides tight feeding mechanism and carries out the delivery to banded material, consequently its cost and the structure complexity that can reduce equipment.

As shown in fig. 1, the strip-shaped material cutting device provided in the embodiment of the application includes a base 1, a mounting frame 2, a pressing mechanism 3 and a cutting mechanism 4, wherein:

the mounting bracket 2 sets up on base 1, is equipped with a plurality of material passageways that run through to the second lateral wall (such as right side wall) of mounting bracket from the first lateral wall (such as left side wall) of mounting bracket on the mounting bracket 2.

The hold-down mechanism 3 is arranged on the first side wall of the mounting frame 2.

The cutting mechanism 4 is arranged on the second side wall of the mounting frame, and a gap with a preset size is kept between the cutting piece of the cutting mechanism 4 and the penetrating end of the material channel.

After passing through the pressing mechanism 3 along the first horizontal direction (such as the X-axis direction in fig. 1), the strip-shaped materials respectively pass through the second side of the mounting frame from a corresponding material channel.

The pressing mechanism 3 is used for pressing the strip-shaped material, and the cutting mechanism 4 is used for cutting the strip-shaped material through a cutting piece to obtain strip-shaped material sections with preset lengths.

It can be seen that, since a predetermined size of the spacing in the first horizontal direction is maintained between the material passage and the cutting member of the cutting mechanism 4, namely: the cutting mechanism 4 does not perform a cutting action against the outlet of the material passage. Therefore, after the strip-shaped material is cut off by the cutting mechanism 4, the cut end of the strip-shaped material still extends out of the material channel outlet and is suspended. In this way, it is ensured that the pulling mechanism can smoothly grip the cut end of the strip-shaped material to pull the strip-shaped material before the next cutting is performed. Adopt the ribbon material cutting device that this application provided, need not to use again to press from both sides tight feed mechanism and implement the delivery to ribbon material, consequently its cost and the structural complexity that can reduce equipment.

The strip-shaped material cutting device is suitable for cutting strip-shaped materials such as film strips and welding strips.

As shown in fig. 2, the pressing mechanism 3 may alternatively include a pressing plate 31, a pad plate 32, and a pad plate driving portion 33, in which: the pressing plate 31 is fixedly mounted on the first side wall of the mounting frame 2. The pad driving portion 33 is provided on the mount 2. The pad plate 32 is connected to a driving end of the pad plate driving portion 33 and is disposed opposite to the pressing plate 31 up and down, the belt-shaped material passes through between the pressing plate 31 and the pad plate 32, and the pad plate driving portion 33 drives the pad plate 32 to lift toward or away from the pressing plate 31, thereby performing pressing or releasing of the belt-shaped material.

In the embodiment shown in fig. 2, the backing plate 32 is located below the platen 31. The pad driving unit 33 includes two lift driving cylinders provided in pairs on both sides of the mounting frame 2, and both ends of the pad 32 are connected to one of the lift driving cylinders, respectively, and when the two lift driving cylinders synchronously drive the pad 32 to rise, the pad driving unit compresses the belt-like material, and when the two lift driving cylinders synchronously drive the pad 32 to fall, the release of the belt-like material is performed. Of course, in alternative embodiments, the backing plate 32 may be disposed above the platen 31.

Optionally, the pressing mechanism 3 further includes a plurality of elastic pressing rods 34 disposed on the pressing plate 31 side by side along a second horizontal direction (e.g., Y-axis direction in fig. 2) perpendicular to the first horizontal direction. When the pad driving portion 33 drives the pad 32 to move toward the pressing plate 31, each elastic pressing rod 34 is used for elastically pressing a piece of strip-shaped material on the pad 32, so that all strip-shaped materials can be ensured to be pressed. In order to prevent the compacted strip from adhering to the backing plate 32, an anti-adhesive layer is optionally provided on the side of the backing plate 32 that is in contact with the strip.

With continued reference to fig. 2, the pressing mechanism 3 may optionally further include a guide rod 35, wherein the guide rod 35 passes through the backing plate 32, one end of the guide rod 35 is connected to the pressing plate 31, and the other end of the guide rod 35 is connected to the mounting frame 2. The pad driving unit 33 drives the pad 32 to move up and down along the guide rod 35. By providing the guide rod 35, lifting guide of the base plate 32 is realized, and the base plate 32 is prevented from being deviated.

As shown in fig. 3 to 5, optionally, a plurality of guiding-out components 5 are provided on the mounting frame 2, each guiding-out component 5 includes a supporting block 51 and an adsorbing block 52, wherein: the supporting block 51 is formed with a material passage 53 as described above, the adsorbing block 52 is located above the supporting block 51, and the adsorbing block 52 is used for adsorbing the strip-shaped material located in the material passage 53.

After the part of the strip-shaped material in the compressing mechanism 3 is compressed by the compressing mechanism 3, the strip-shaped material in the material channel is absorbed by the absorbing block 52, and the strip-shaped material to be cut extends out of the outlet of the material channel 53. Thus, sagging of the strip-like material to be cut off can be prevented, and the cutting mechanism 4 cannot smoothly perform the cutting operation.

As shown in fig. 3 to 4, the cutting mechanism 4 includes two cutting members symmetrically disposed on the mounting frame 2 in the second horizontal direction, and the two cutting members synchronously perform cutting operations on the belt-like material. By providing two cutting members, the cutting members can be arranged on the two cutting members on average, thereby shortening the length dimension of a single cutting member, and eventually reducing the load of the driving member of the cutting member, so that the cutting member can be moved more smoothly and the cutting operation can be performed.

Of course, it is also possible to provide only one cutting assembly, in which case all cutting elements are arranged.

Since the structure and the cutting principle of the two cutting members are the same, the structure and the cutting principle of the cutting member will be exemplarily described below by taking only the cutting member located at one side (e.g., the right side) thereof as an example.

The tool holder 41 is slidably coupled to the second side wall of the mounting frame 2 and to the drive end of the tool holder drive mechanism 42. The plurality of cutting members 43 are disposed on the tool rest 41 side by side along the second horizontal direction (e.g., the Y-axis direction in the drawing), and each cutting member 43 corresponds to one material channel 53 and is used for cutting off the strip-shaped material passing through the corresponding material channel 53. The cutter frame driving mechanism 42 is used for driving the cutter frame 41 to slide on the mounting frame 2 along the second horizontal direction so as to drive each cutting piece 43 to move between the respective avoiding position and the cutting position.

When the cutting member 43 moves to the corresponding cutting position, the cutting member 43 is aligned with the corresponding material passage 53, and a predetermined space is formed between the cutting member and the outlet of the material passage 53. At this time, the cutter 43 may perform a cutting operation of the strip-shaped material passing out from the corresponding material passage 53.

After the cutting operation of the strip-shaped material is completed, when the cutting member 43 is moved to the corresponding avoiding position, the cutting member 43 is staggered from the corresponding material passage 63. At this time, the pulling mechanism may grip the cut end of the projected strip material from the material passage 63 to perform pulling of the strip material before the next cutting is performed.

As shown in fig. 3 to 4, the cutting mechanism 4 may further include a first stopper 44, and the first stopper 44 is provided on the mounting bracket 2 and located on one side (left side in the drawing) of the cutter holder 41.

The tool holder 41 comprises a first slide plate 411 and a second slide plate 412, wherein: the first sliding plate 411 is slidably connected to the second side wall of the mounting frame 2 and is connected to the driving end of the tool rest driving mechanism 42, the tool rest driving mechanism 42 drives the first sliding plate 411 to slide on the mounting frame 2 along the second horizontal direction, a plurality of groups of waist-shaped holes are formed in the first sliding plate 411, each group of waist-shaped holes comprises a first waist-shaped hole 413 and a second waist-shaped hole 414 which are vertically symmetrically arranged, an included angle smaller than 90 degrees is formed between the first waist-shaped hole 413 and the second waist-shaped hole 414, and the included angle is opened towards the first limiting part 44. The second slide plate 412 is slidably coupled to the first slide plate 411 and is capable of sliding on the first slide plate 411 in the second horizontal direction.

The cutting member 43 is a pair of scissors, wherein a rotating shaft of the pair of scissors is connected to the second sliding plate 412, a first tail end of the pair of scissors is slidably connected in the first waist-shaped hole 413 and can slide along the first waist-shaped hole 413, a second tail end of the pair of scissors is slidably connected in the second waist-shaped hole 414 and can slide along the second waist-shaped hole, and a cutting end of the pair of scissors faces the first limiting member 44. Optionally, rollers are mounted at the first tail end and the second tail end of the scissors, the rollers at the first tail end of the scissors are located in the first waist-shaped holes 413 and can roll in the first waist-shaped holes 413, and the rollers at the second tail end of the scissors are located in the second waist-shaped holes 414 and can roll in the second waist-shaped holes 414.

Optionally, a spring 46 is further disposed between the first slide plate 411 and the second slide plate 412, and the spring 46 tends to pull the second slide plate 412, thereby causing the shearing ends of the scissors to be in an open state.

The specific cutting process of the cutting mechanism 4 is as follows:

in the initial state, the first sliding plate 411 is far away from the first limiting member 44, and each pair of scissors is at the avoiding position and is staggered from the corresponding material channel 63.

When the cutting operation needs to be performed, the knife rest driving mechanism 42 first drives the first sliding plate 411 to slide towards the first limiting member 44 to the first position, so that the second sliding plate 412 abuts against the first limiting member 44, and the cutting ends of the scissors reach the corresponding cutting positions.

The tool rest driving mechanism 42 continues to drive the first sliding plate 411 to slide towards the first limiting member 44 to the second position, and in this process, since the second sliding plate 412 is abutted by the first limiting member 44, a relative displacement is generated between the first sliding plate 411 and the second sliding plate 412. The first tail end and the second tail end of each pair of scissors are pressed, and slide close under the guidance of the first waist-shaped hole 413 and the second waist-shaped hole 414, so that the shearing ends of the scissors are driven to be closed, and the strip-shaped materials penetrating from the corresponding material channels are cut off.

After the cutting operation is completed, the first sliding plate 411 of the cutter holder driving mechanism 42 is slid and reset away from the first limiting member 44, so that each pair of scissors returns to the original avoiding position, and meanwhile, the spring 46 is in decompression and reset, so that the second sliding plate 412 is driven to slide and reset relative to the first sliding plate 411, and the shearing ends of each pair of scissors are restored to the open state.

It can be seen that by providing the first stop 44, and by providing the structure of the tool holder 41 as described above. In the sliding process of the second sliding plate 412 driven by the knife rest driving mechanism 42, the position of the cutting member 43 between the cutting position and the avoiding position can be driven to switch, and the cutting member 43 can be driven to perform the cutting action. That is, the blade holder driving mechanism 42 realizes both the translational driving of the cut piece 43 and the cutting-off driving of the cut piece 43, thereby further reducing the complexity of the apparatus.

Optionally, the cutting mechanism 4 further includes a second limiting member 45, where the second limiting member 45 is disposed on the mounting frame 2 and located on the same side of the tool holder as the first limiting member 44. When the first sliding plate 411 continues to slide towards the first limiting member 44 to the second position, the first sliding plate 411 finally abuts against the second limiting member 45.

By providing the second limiting member 45, the sliding limitation of the first sliding plate 411 is realized, and the first sliding plate 411 is prevented from excessively sliding, which causes damage to the cutting 43.
