It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The material clamping assembly 100, the material clamping mechanism 200 and the cutting machine 300 according to the embodiments of the present application are described in detail below with reference to fig. 1 to 9 by way of specific embodiments and application scenarios thereof.

The structure of the clamping assembly 100 provided in this embodiment is shown in fig. 1 and 2, and includes a base frame 110, a clamping arm 120, and a driving device 130. The base frame 110 and the clamping arm 120 are both rigid members, and the frame is the mounting base of the clamping arm 120, and the clamping arm 120 is mounted on the base frame 110. The base frame 110 has a support portion 111, and the clamp arm 120 has a clamp portion 121, a rotating portion 122, and a driving portion 123 spaced apart from each other. The clamping part 121 and the supporting part 111 define therebetween a clamping space into which a material to be cut can be placed manually or mechanically. The rotating portion 122 is rotatably connected to the base frame 110, and forms a first hinge position 141, so that the clamping arm 120 can be rotatably connected to the base frame 110 through the rotating portion 122. The driving device 130 is disposed on the base frame 110 so that the base frame 110, the clamping arm 120, and the driving device 130 in the clamping assembly 100 can be integrally moved. The driving device 130 is connected to the driving portion 123, and the driving device 130 can act on the rotating portion 122 and drive the rotating portion 122 to move, so that the clamping arm 120 rotates around the first hinge position 141 as a rotation center, and the clamping arm 120 rotates to drive the clamping portion 121 to synchronously rotate, so that the clamping portion 121 moves towards the supporting portion 111 or moves away from the supporting portion 111. When the clamping part 121 moves towards the supporting part 111, the clamping space can be reduced by matching with the supporting part 111 so as to clamp and fix the material to be cut of the material placed in the clamping space; conversely, when the clamping part 121 moves away from the supporting part 111, the clamping space can be enlarged in cooperation with the supporting part 111, so as to release the clamping of the material placed in the clamping space.

It should be noted that in some alternative embodiments, the driving device 130 may also be provided on other structural members, for example, after the clamping assembly 100 is mounted on the cutting apparatus, the driving device 130 may be provided on other components of the cutting apparatus.

Since the clamping portion 121 is displaced along with the rotation of the rotating portion 122, and the raw material of the CCL is usually a plate, when the clamping portion 121 cooperates with the supporting portion 111 to clamp the material, the position of the clamping portion 121 abutting against the material is also changed. In order to reduce the risk that the clamping force generated by the clamping assembly 100 to the material when clamping the material causes damage to the material, in the clamping assembly 100, the arc-shaped abutting surface 121a is arranged on the clamping portion 121, when the clamping portion 121 is matched with the supporting portion 111 to clamp materials with different thicknesses, the clamping portion 121 is always contacted with the material through the arc-shaped abutting surface 121a, compared with the contact with the material through the edges and corners, the phenomenon of stress concentration can be effectively reduced by the arc-shaped surface, so that the probability that the material is damaged after being subjected to the clamping force is reduced, and then the yield of the material obtained after cutting is improved to a certain extent.

Preferably, the arc-shaped abutting surface 121a can be selected to be a half arc surface or a major arc surface, so that the material clamping space can adapt to more material thickness on the premise that the arc-shaped abutting surface 121a contacts with the material. Meanwhile, after the diameter of the arc-shaped abutting surface 121a is increased, the occurrence of shallower indentations on the material can be reduced to a certain extent, and no indentations are generated, so that the damage probability of the material is further reduced.

In this embodiment, the clamping portion 121 and the supporting portion 111 are correspondingly disposed, that is, the supporting portion 111 is located on the moving path of the clamping portion 121, so that after the clamping assembly 100 clamps the material, uneven stress on the material caused by dislocation of the supporting portion 111 and the clamping portion 121 can be avoided, and then bending deformation of the material is caused to form surface defects.

After the material enters the clamping space and is clamped by the supporting portion 111 and the clamping portion 121, the material needs to be cut, and the direction of the material when the material is cut is the first direction. For better clamping and fixing the material, a plurality of clamping portions 121 are disposed on the clamping arm 120 along the first direction, and/or a plurality of supporting portions 111 are disposed on the base frame 110. The materials are clamped at multiple points through the clamping parts 121 or the supporting parts 111, so that the materials are prevented from moving in the cutting process. Especially when the size of the material to be cut is small and can be clamped by only one clamping assembly 100, the structure can realize multi-point clamping on one clamping assembly 100, so that more stable clamping force can be provided for the material with small size.

As shown in fig. 1, in a specific arrangement manner of the clamping portion 121 and/or the supporting portion 111 in the clamping assembly 100, a plurality of clamping portions 121 are provided on the clamping arm 120 along the first direction, and a plurality of supporting portions 111 are provided on the base frame 110, where the number of the supporting portions 111 is identical to the number of the clamping portions 121. Each of the clamping portions 121 corresponds to one of the supporting portions 111. When clamping the material, each corresponding supporting part 111 and clamping part 121 forms a clamping point position on the material, so as to achieve the effect of multi-point clamping.

In some alternative embodiments, the clamping portion 121 and/or the supporting portion 111 in the clamping assembly 100 may be further configured as shown in fig. 3, that is, a plurality of clamping portions 121 are provided on the clamping arm 120, and the number of supporting portions 111 provided on the base frame 110 is smaller than the number of clamping portions 121, and at the same time, the width of the supporting portion 111 is widened, so that one supporting portion 111 can simultaneously cooperate with at least two clamping portions 121 and achieve clamping. This also enables multi-point clamping of material in one clamping assembly 100. In addition, in some alternative embodiments, a structure as shown in fig. 4 may be further provided, that is, a plurality of supporting parts 111 are provided on the base frame 110 at intervals along the first direction, and the number of clamping parts 121 provided on the clamping arm 120 is smaller than the number of supporting parts 111, and at the same time, the width of the clamping parts 121 is widened, so that one clamping part 121 can simultaneously cooperate with at least two supporting parts 111 and realize clamping, so as to realize the function of multi-point clamping.

One embodiment of the driving device 130 includes a telescopic device, which has a telescopic function and a controllable length thereof. One end of the telescopic device in the telescopic direction is rotatably connected with the base frame 110, and the other end of the telescopic device in the telescopic direction is rotatably connected with the driving part 123 of the clamping arm 120, so that the clamping arm 120 is driven to rotate around the rotating part 122 in the telescopic process through the telescopic device.

Specifically, the telescopic device is provided with a fixed end and a telescopic end, and the telescopic end can move relative to the fixed end under the action of a driving force so as to realize a telescopic function. The telescopic device can be a device capable of realizing telescopic function, such as an air cylinder, an oil cylinder, an electric push rod and the like, and the specific selection of the telescopic device is not limited in this embodiment. In the telescopic device used in the present embodiment, the fixed end of the telescopic device is rotatably connected to the base frame 110, and the telescopic end of the telescopic device is rotatably connected to the driving portion 123 of the clamping arm 120. Of course, in some alternative embodiments, the fixed end of the telescopic device may be rotatably connected to the driving portion 123 of the clamping arm 120, and the telescopic end of the telescopic device may be rotatably connected to the base frame 110.

Through all adopting articulated mode to telescoping device's flexible end and stiff end, can make telescoping device can follow the swing of arm 120 and carry out corresponding swing at flexible in-process to make arm 120 can have great swing angle, with the material of centre gripping bigger thickness scope.

It should be noted that, in some alternative embodiments, the driving device 130 may be a traction rope device, where a rope in the traction rope device is fixed to the driving portion 123 of the clamping arm 120, and a device capable of being connected to the rope and controlling the movement of the rope, such as a winch or a linear sliding rail driving the traction rope to move in the traction rope device, is used to drive the rotation of the clamping portion 121, so as to drive the clamping arm 120.

When the telescopic device is used as the driving device 130, the rotatable connection position between the driving device 130 and the driving portion 123 is referred to as a second hinge position 142, the rotatable connection position between the driving device 130 and the base frame 110 is referred to as a third hinge position 143, and an angle α between a straight line where the first hinge position 141 and the second hinge position 142 are located and a straight line where the second hinge position 142 and the third hinge position 143 are located is equal to or smaller than 90 °. Thus, when the telescopic device stretches out and draws back at a constant speed, the rotating speed of the clamping arm 120 is faster when the telescopic device drives the clamping arm 120 to rotate, the clamping time for clamping materials or the clamping releasing time is shorter, and the effect of rapidly clamping materials or rapidly releasing the clamping is achieved. When the thus-arranged clamping assembly 100 is applied to the cutter 300, the working efficiency of the cutter 300 can be improved to some extent. Because the clamping portion 121 in the clamping assembly 100 adopts the arc-shaped abutting surface 121a, the force to be received can be uniformly diffused to other positions, and even if the clamping time of the clamping assembly 100 is shorter, the clamping assembly 100 does not cause deep indentation on materials due to larger impact force.

Based on the above-mentioned clamping assembly 100, the present application further provides a clamping mechanism 200, where the structure of the clamping mechanism 200 is shown in fig. 5 to 7, and the clamping mechanism includes a fixing member 210 and the above-mentioned clamping assembly 100. The clamping assemblies 100 are multiple, the clamping assemblies 100 are arranged on the fixing piece 210 at intervals along the first direction, and the clamping assemblies 100 are fixed on the fixing piece 210 through the base frame 110, so that the clamping mechanism 200 can form a whole, and movement is facilitated. The plurality of clamping assemblies 100 are arranged along the first direction, and when clamping materials with larger sizes, the plurality of clamping assemblies 100 simultaneously clamp the materials, so that different positions of the materials are clamped through the plurality of clamping assemblies 100, and multi-point clamping with the clamping assemblies 100 as clamping positions is formed. On the one hand, the clamping adaptability to materials with different sizes is improved, and on the other hand, the clamping stability to the materials can be further improved. The first direction here also refers to the direction in which the material is cut.

When the material is cut, the material is usually cut from one end of the material to the other end of the material along the first direction, so that the effect of cutting the material is achieved. After being cut, the section of the partial CCL plate has an uneven state, so that certain flaws exist between the size of the cut CCL plate and the size of the target, and the flaws may have certain influence if certain requirements are made on the flatness of the section in the subsequent process of further processing or assembling the CCL plate. For example, when the cut surface is used as the reference surface during further processing of the CCL board, the processed product may be defective due to the change of the reference surface caused by the uneven cut surface, or the CCL board may not be installed in a preset space due to the uneven cut surface during the installation of the CCL board.

The inventor finds that the positions of the materials with uneven sections are mostly concentrated at the starting positions of the materials to be cut. One of the reasons for this is that the circular saw 320 may shake the edge of the material when the material is cut just before the material is cut, which may cause uneven cutting surface at the starting position.

In view of this, the present embodiment further optimizes the above-described material clamping mechanism 200. In the present embodiment, among the plurality of clamping assemblies 100 arranged at intervals along the first direction, the width of the supporting portion 111 in the first clamping assembly 100a along the first direction is widened, so that the width of the supporting portion 111 in the first clamping assembly 100a is greater than the width of the supporting portions 111 in the rest of clamping assemblies along the first direction. Meanwhile, the width of the clamping part 121 in the first clamping assembly 100a along the first direction is widened, so that the width of the clamping part 121 in the first clamping assembly 100a is larger than the width of the clamping parts 121 in the rest clamping assemblies along the first direction. With this arrangement, the gripping width of the first gripping mechanism 200 against the material in the first direction is increased. The probability of shaking of the material is reduced to a certain extent, so that the probability of uneven section of the material is reduced.

Of course, in some alternative embodiments, the lengths of the supporting portion 111 and the clamping portion 121 corresponding to the first clamping assembly 100a may be increased in the plurality of clamping assemblies 100 arranged at intervals along the first direction, so that the lengths of the supporting portion 111 and the clamping portion 121 in the first clamping assembly 100 are greater than those of the supporting portion 111 and the clamping portion 121 in the remaining clamping assemblies, so that the first clamping assembly 100a has a larger contact area with the material after clamping the material, thereby reducing the probability of shaking of the material to some extent. The length increase of the supporting portion 111 and the clamping portion 121 and the width increase of the supporting portion 111 and the clamping portion 121 may be separately provided, or may be simultaneously applied, and a better shake preventing effect may be achieved when the same is applied.

In addition, it should be noted that in some alternative embodiments, the spacing between the plurality of nip assemblies 100 may be adjustable, so that the spacing between the nip assemblies 100 may be adjusted according to the thickness of the material. For thinner materials, the distance between two adjacent clamping assemblies 100 can be properly reduced, so as to avoid the phenomenon of shaking the materials greatly.

Preferably, in the first direction, the spacing between a first clamping assembly 100a and its adjacent clamping assembly 100 is less than the spacing between the remaining clamping assemblies 100. The material is cut along the first direction, and the position of the material, which is just cut, is the initial cutting position of the material, so that the distance between the first clamping component 100a and the adjacent clamping component 100 is reduced in this way, so that the initial cutting position of the material has larger clamping and supporting area, and the phenomenon that the material shakes greatly is further reduced. On this basis, because after the gap is cut out by circular saw 320 to the material, circular saw 320 then can play certain limiting displacement to the lateral wall in gap to make circular saw 320 more smooth and easy at the cutting material in-process, the position of being cut still has clamp material subassembly 100 to the material to carry out the centre gripping simultaneously, consequently, this embodiment can also follow the interval between all clamp material subassemblies 100 and increase gradually and set up, in order to satisfy the condition to the material centre gripping, reduce the quantity of the clamp material subassembly that acts on the material.

In addition, in the present embodiment, if the clamping heights of the plurality of clamping assemblies 100 on the material are different, the material is uneven, and thus the cut section of the cut material may have uneven section.

In view of this, in the clamping mechanism 200 provided in the present embodiment, the base frame 110 is swingably connected to the fixing member 210, and an independent adjusting assembly 220 is disposed between the base frame 110 and the fixing member 210 of each clamping assembly 100, and the adjusting assembly 220 can adjust the swinging angle of the corresponding base frame 110 relative to the fixing member 210, so that when the clamping mechanism 200 is mounted on the cutting machine 300, different clamping assemblies 100 can be adjusted by controlling different adjusting assemblies 220, so that the heights of the clamping assemblies 100 after clamping materials are consistent.

Specifically, the base frame 110 of the clamping assembly 100 is provided with a hoop ring 112, the fixing member 210 is provided with a connecting rod 211 adapted to the hoop ring 112, the hoop ring 112 is sleeved on the connecting rod 211, so that the clamping assembly 100 swings relative to the fixing member 210, and the hoop ring 112 is screwed on the connecting rod 211, so that the fixing between the base frame 110 and the fixing member 210 can be realized. Meanwhile, due to the adoption of the installation mode of the hoop ring 112, the distance between two adjacent clamping assemblies 100 can be adjusted arbitrarily, so that materials with different sizes can be adapted by adjusting the distance between the two adjacent clamping assemblies 100, and the phenomenon of large-amplitude shaking of the materials is avoided.

Of course, in alternative embodiments, other structures capable of swinging may be employed, such as swinging by way of a gear engagement. In addition, it should be noted that the swinging position of the base frame 110 is spaced from the supporting portion 111 on the base frame 110, so that the horizontal height of the supporting portion 111 on the base frame 110 can be adjusted during the swinging process of the base frame 110.

Further, the adjusting assembly 220 includes a slider 222 and an adjusting rod 221, the slider 222 is connected to the fixing member 210 through the adjusting rod 221, and the base frame 110 is slidably connected to the slider 222. In addition, the adjusting lever 221 drives the slider 222 to move, and the slider 222 can drive the base frame 110 to swing during the moving process. Thereby controlling the movement amount of the sliding block 222 through the adjusting rod 221, and achieving the effect of precisely controlling the swing angle of the clamping assembly 100.

It should be noted that in this embodiment, the adjusting rod 221 is a bolt, the threaded section of the adjusting rod 221 passes through the through hole on the slider 222 and then is connected to the fixing member 210, and the fixing member 210 is attached to the slider 222, so that the fixing member has a guiding effect on the slider 222, and when the adjusting rod 221 is screwed, the slider 222 can slide linearly under the driving of the nut of the adjusting rod 221 and the guiding effect of the fixing member 210. The side of the slider 222 slidably connected to the base frame 110 is a slope 222a, and the slope direction of the slope 222a intersects with the sliding direction of the slider 222. The base frame 110 is provided with a protruding sliding portion 150, and the sliding portion 150 abuts against the inclined surface 222a of the slider 222. The slider 222 can slide the sliding portion 150 on the inclined surface 222a during the sliding process, thereby achieving the swinging of the base frame 110.

Of course, in some alternative embodiments, the adjusting assembly 220 may be configured as a gear-rack engaged engagement mechanism, the rack may be movably disposed on the fixing member 210, and the gear may be rotatably disposed on the base frame 110, so as to drive the base frame 110 to swing by moving the rack.

Further, based on the above-mentioned material clamping mechanism 200, a cutting machine 300 is further provided in this embodiment, and the cutting machine 300 has a structure as shown in fig. 8 and 9, and includes a workbench 310 and the material clamping mechanism 200, and a circular saw 320 that can move along the first direction is disposed on the workbench 310. The fixing member 210 on the clamping mechanism 200 is slidably connected to the table 310, and the sliding direction of the clamping mechanism 200 is a second direction, where the second direction refers to a direction intersecting the first direction in a plane of the table surface of the table 310, that is, the second direction intersects the first direction. The plurality of clamping assemblies 100 in the clamping mechanism 200 are also spaced apart along the first direction. A guide chute 311 is provided on the table surface of the table 310, the guide chute 311 is provided in the second direction, and the support portion 111 is positioned in the guide chute 311. Therefore, the supporting part 111 on the base frame 110 can be matched with the rotating part 122 to clamp materials, and meanwhile, the supporting part 111 can also play a certain guiding role on the movement of the clamping mechanism 200. From another aspect, the guiding chute 311 is provided, which not only can limit the supporting portion 111, but also can accommodate the supporting portion 111, so that the overall height of the supporting portion 111 is reduced, and the phenomenon that the surface of the supporting portion 111, which is in clamping contact with the material, is far higher than the material tilting caused by the working platform is avoided.

Preferably, the first direction and the second direction intersect perpendicularly. The surface of the supporting part 111, which is in clamping contact with the material, is flush with the table surface of the workbench 310, so that the material can be cut by being better matched with the circular saw 320.
