Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In this embodiment, the material is a welding strip 105 .

[0033] The present application provides a clamping mechanism 100, including a clamping assembly 20, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the clamping jaw assembly 20 includes a fixed clamping jaw 22 and a movable clamping jaw 24 which are arranged opposite to each other. The fixed clamping jaw 22 and the movable clamping jaw 24 are arranged to open and close along the first direction A to clamp the welding strip 105 from both sides in the width direction of the welding strip. The movable clamping jaw 24 is hinged to the fixed clamping jaw 22. The fixed clamping jaw 22 is provided with a first reference surface 223 and a second reference surface 224 at the head end for clamping the welding strip 105. The movable clamping jaw 24 is provided with a third reference surface 245 and a supporting inclined surface 246 which is arranged at an obtuse angle to the third reference surface 245 at the head end for clamping the welding strip 105. The first reference surface 223 and the third reference surface 245 are arranged opposite to each other in the first direction A, and the second reference surface 224 is located above the supporting inclined surface 246. The movable clamping jaw 24 moves toward the fixed clamping jaw 22 so that the first reference surface 223 and the third reference surface 245 clamp the welding strip from both sides in the width direction of the welding strip to prevent the welding strip 105 from being in the first direction A ( Figure 3 The position of the second reference surface 223 and the supporting inclined surface 246 is shifted from the second direction B ( Figure 3 The solder strip 105 is clamped by the jaw assembly 20 (in the solder strip thickness direction) to prevent the solder strip 105 from moving in the solder strip thickness direction and to prevent the solder strip 105 from rotating. Through the clamping jaw assembly 20 of this structure, the positioning accuracy of the solder strip clamping can be improved.

[0034] The first direction A is the width direction of the welding strip, and the second direction B is the thickness direction of the welding strip.

[0035] from Figure 1-Figure 3 It can be seen from the perspective that the clamping jaw assembly 20 as a whole presents a vertical posture, and the fixed clamping jaw 22 and the movable clamping jaw 24 clamp the two sides of the welding ribbon 105 from the width direction of the welding ribbon, and the welding ribbon 105 extends along the front-to-back direction (the front-to-back direction is perpendicular to the first direction and the second direction, not shown in the figure).

[0036] Taking the flat solder strip 105, i.e., the cross section of which is rectangular, as an example, the first reference plane 223 and the third reference plane 245 are planes parallel to each other and parallel to the side of the solder strip 105 in the width direction, forming a positioning reference plane in the width direction of the solder strip, and the second reference plane 224 is a plane perpendicular to the first reference plane 223 and the third reference plane 245, forming an upper positioning reference plane above the solder strip 105, and cooperating with the supporting inclined plane 246. During operation, the movable clamping jaw 24 moves toward the fixed clamping jaw 22, clamping the solder strip 105 from all sides, so that the clamping of the solder strip 105 is stable and reliable, and the solder strip 105 is prevented from falling off during the clamping process.

[0037] Specifically, during the clamping process, the support inclined surface 246 is provided to form a larger clamping opening so that the welding strip 105 can be accommodated in the accommodation space formed by the four surfaces. Then, the support inclined surface 246 can also drive the welding strip 105 to gradually move to contact with the first reference surface 223 and the second reference surface 224, and cooperate with the third reference surface 245 to achieve stable and reliable clamping of the welding strip 105. The first reference surface 223 and the second reference surface 224 of the fixed clamping jaw 22 are contacted and positioned with the welding strip, and the first reference surface 223 and the second reference surface 224 can ensure the positioning accuracy of the welding strip. Then, the movable clamping jaw 24 moves so that the third reference surface 245 thereon cooperates with the first reference surface 223 to clamp the welding strip 105 from both sides in the width direction of the welding strip, and the support inclined surface 246 and the second reference surface 224 clamp the welding strip in the thickness direction of the welding strip, which can simultaneously achieve accurate positioning and reliable clamping of the welding strip 105 when clamping.

[0038] Of course, this structure is also applicable to circular welding strips or welding strips of other shapes, and can also locate the width and thickness directions of the welding strips. The first reference plane 223, the second reference plane 224, the third reference plane 245 and the supporting inclined plane 246 can be set to corresponding planes or curved surfaces and set to appropriate angles as required.

[0039] As another example, see Figure 2 The clamping jaw assembly 20 further includes a first elastic member 26, which is disposed between the fixed clamping jaw 22 and the movable clamping jaw 24, and is used to provide elastic force to drive the movable clamping jaw 24 and the fixed clamping jaw 22 to clamp each other. In other words, when (the driving tooth 344 below) does not apply an action force to the movable clamping jaw 24, the elastic force provided by the first elastic member 26 causes the head end of the movable clamping jaw 24 to abut against the head end of the fixed clamping jaw 22, so that the head end of the movable clamping jaw 24 and the head end of the fixed clamping jaw 22 cooperate to clamp the welding strip 105; and when an action force is applied to the movable clamping jaw 24, the movable clamping jaw 24 swings, and the head end of the movable clamping jaw 24 is away from the head end of the fixed clamping jaw 22, so that it opens to release the welding strip 105.

[0040] In this embodiment, the first elastic member 26 is a compression spring. By selecting a suitable first elastic member 26, it can be effectively ensured that each jaw assembly 20 clamps the material reliably, stably and without damaging the material, and effectively avoid the situation where the material is unstable or easily damaged when clamping the material due to the low control accuracy of applying the external driving force.

[0041] Furthermore, a first countersunk hole 220 is provided on one side of the fixed jaw 22 facing the movable jaw 24, a second countersunk hole 240 is provided on one side of the movable jaw 24 facing the fixed jaw 22, and two ends of the first elastic member 26 are respectively accommodated in the first countersunk hole 220 and the second countersunk hole 240. The two ends of the first elastic member 26 are fixed by providing the countersunk holes, which is simple and has low processing requirements for the fixed jaw 22 and the movable jaw 24, and can achieve good connectivity.

[0042] When the clamping mechanism 100 includes a plurality of clamping assemblies 20 , each clamping assembly 20 includes a first elastic member 26 , and the first elastic members 26 are arranged to have the same specifications, so that the clamping force of each clamping assembly 20 on the material can be kept consistent.

[0043] As another example, see Figure 4 and Figure 5 The number of the clamping jaw assemblies 20 in the clamping jaw mechanism 100 provided in the present application is multiple, and the clamping jaw mechanism 100 also includes a base 10 and a plug assembly 30, the plug assembly 30 includes a plug board 34, and the multiple clamping jaw assemblies 20 are arranged in a row on the base 10, and can be arranged in a row and spaced on one side of the base 10 (or arranged in a row and distributed below the base 10 when space permits), and the fixed clamping jaws 22 in each clamping jaw assembly 20 are fixed to the base 10, for example, by fasteners such as screws or pins to connect the fixed clamping jaws 22 to the base. 10, and multiple fixed jaws are aligned in the up and down directions; the insert plate 34 includes a crossbeam 342 and a plurality of driving teeth 344 connected to the crossbeam 342 in a row, the driving teeth 344 are arranged corresponding to one or two movable jaws 24, that is, one driving tooth 344 can drive one movable jaw 24 or two movable jaws 24 to move, the driving teeth 344 are used to drive the corresponding movable jaws 24 to swing, and the insert plate 34 is used to drive multiple movable jaws 24 to swing at the same time, so as to cooperate with multiple fixed jaws 22 to clamp or open at the same time.

[0044] Specifically, the driving tooth 344 acts on the rear end of the movable jaw 24, which can drive the movable jaw 24 to swing, so that the front end of the movable jaw 24 moves toward the front end of the fixed jaw 22 to achieve a clamping action, and / or the front end of the movable jaw 24 moves away from the front end of the fixed jaw 22 to achieve an opening action. Further, when one driving tooth 344 drives two movable jaws 24, it is necessary to arrange the movable jaws 24 of two adjacent jaw assemblies 20 adjacent to each other and the driving tooth 244 is arranged between the two movable jaws 24 of the two adjacent clamping assemblies 20.

[0045] In this embodiment, Figure 5 As shown, the driving tooth 344 is located at the rear end of the movable jaw 24 and acts on the side of the movable jaw 24 away from the fixed jaw 22 to drive the movable jaw 24 to open relative to the fixed jaw 22. Optionally, the driving tooth 344 can also act on the side of the movable jaw 24 toward the fixed jaw 22 to drive the movable jaw 24 to clamp relative to the fixed jaw 22.

[0046] In the present application, a plurality of jaw assemblies 20 are arranged on the base at the same time, and each driving tooth 344 on the insert plate 34 drives the corresponding movable jaw 24 to swing at the same time, so that the plurality of jaw assemblies 20 in the jaw mechanism 100 can clamp or open at the same time, thereby achieving synchronous clamping or release of multiple materials, and effectively improving the working efficiency of the jaw mechanism 100.

[0047] It should be noted that the example of the present application drives the movable jaw 24 to move in the form of up and down movement of the driving tooth 344, but as other cases, the driving tooth 344 can also drive the movable jaw 24 to move in the form of movement along the first direction A, but when moving up and down, if multiple jaw mechanisms 100 are included, the arrangement direction of the multiple jaw mechanisms 100 is more flexible, especially when the driving teeth of the multiple jaw mechanisms 100 are driven by the same driving actuator.

[0048] Furthermore, the fixed jaw 22 is connected to the base 10 in a vertical posture, and the driving teeth 344 are offset relative to the fixed jaw 22 along the first direction A and are used to perform lifting motion along the vertical direction, thereby driving the movable jaw 24 to swing relative to the fixed jaw 22.

[0049] As another example, Figure 5 As shown, the tail end of the movable jaw 24 is provided with a first plane 241 and a first curved surface 242 connected to each other, and one side of the driving tooth 344 is provided with a second plane 345 and a third plane 346 connected to each other, and the second plane 345 is inclined relative to the third plane 346, and the second plane 345 is used to abut the first curved surface 242, thereby driving the movable jaw 24 to swing, and the third plane 346 is used to fit with the first plane 241, thereby controlling the opening angle of the movable jaw 24 relative to the fixed jaw 22.

[0050] The first arc surface 242 is an outwardly convex arc surface. The first arc surface 242 can be in contact with or spaced from the second plane 345 at the initial stage. During the downward movement of the driving tooth 344, the second plane 345 is in line contact with the first arc surface 242, which can reduce movement friction. At the same time, the second plane 345 slides downward relative to the first arc surface 242, thereby applying a force to the tail end of the movable jaw 24, so that the movable jaw 24 gradually opens relative to the fixed jaw 22. When the second plane 345 is out of contact with the first arc surface 242 and the third plane 346 is in contact with the first plane 241, the opening angles of each movable jaw 24 relative to the corresponding fixed jaw 22 can be kept consistent, further improving the movement synchronization of each movable jaw 24. When the driving tooth 344 rises, the third plane 346 breaks contact with the first plane 241. Then, driven by the elastic force of the first elastic member 26, the movable jaw 24 gradually closes relative to the fixed jaw 22, and the second plane 345 is in line contact with the first arc surface 242. When the driving tooth 344 rises to the final position, the movable jaw 24 and the fixed jaw 22 complete the clamping of the material.

[0051] As another example, see Figure 1 The tail end of the fixed clamping jaw 22 is provided with a round hole 201 and at least one elliptical hole 202. Preferably, there are two elliptical holes 202, which are located on both sides of the round hole 201. The fixed clamping jaw 22 is connected to the base 10 by screws passing through the round holes 201, wherein the size of the round holes 201 is larger than the size of the screws, so as to fine-tune the position of the fixed clamping jaw 22, and a pin is passed through the elliptical hole 202 to connect with the base 10 to correct the position accuracy of the fixed clamping jaw 22. By providing the elliptical hole 202, the positioning accuracy of the fixed clamping jaw 22 is improved, the positioning consistency of multiple welding strips is achieved, and the usability of the clamping jaw mechanism is improved.

[0052] As another example, Figure 4 As shown, the clamp mechanism 100 also includes a guide member 32 slidably connected to the base 10 in the up-down direction, and the plug plate 34 is connected to the guide member 32. The guide member 32 allows the plug plate 34 to move in the up-down direction, and the plug plate 34 moves stably, reduces motion errors, and improves the driving accuracy of the driving teeth 344 on the moving clamp 24, thereby achieving synchronous driving of each moving clamp 24, and the driving effect achieved can be consistent. Among them, it can be considered that the guide member 32 is also a part of the plug plate assembly 30, that is, the plug plate assembly 30 includes the guide member 32 and the plug plate 34.

[0053] More specifically, the guide member 32 can be connected to the base 10 in various ways, such as the guide rod 322 described below that cooperates with the linear bearing 13 embedded in the base 10, or a directional slide rail is provided on one side of the base 10 to cooperate with a slider, and the plug plate 34 is connected to the slider to move in the up and down direction. Of course, other guide members 32 that can achieve stable movement of the plug plate 34 in the up and down direction are within the protection scope of this patent.

[0054] Further, as one form, at least two guide holes 101 (arranged in a direction parallel to the extension direction of the beam 342) are provided on the base 10, and a linear bearing 13 extending in the up-down direction is installed in the guide hole 101. The guide member 32 includes a strip seat 320 (the extension direction is parallel to the extension direction of the beam 342), and at least two guide rods 322 connected to the strip seat 320. The guide rod 322 is installed in the linear bearing 13, and the guide rod 322 is slidably matched with the corresponding linear bearing 13, and the plug plate 34 is connected to the strip seat 320. By providing a linear bearing 13 in each guide hole 101, and the guide rod 322 is assembled with the linear bearing 13, each guide rod 322 moves more smoothly and has a higher movement accuracy, so that the strip seat 320 drives the plug plate 34 to move with high efficiency and high accuracy.

[0055] The present application arranges a plurality of clamping jaw assemblies 20 on one side of the base 10 at the same time, and the guide member 32 in the plug plate assembly 30 is slidably matched with the linear bearing 13 of the base 10, and the guide member 32 also drives the plug plate 34 to move, so that each driving tooth 344 on the plug plate 34 simultaneously drives the corresponding movable clamping jaw 24 to swing, so that the plurality of clamping jaw assemblies 20 in the clamping jaw mechanism 100 can clamp or open at the same time, realize the synchronous clamping or release of multiple materials, and effectively improve the working efficiency of the clamping jaw mechanism 100, wherein the sliding match between the guide member 32 and the linear bearing 13 The combination can ensure the stable movement of the guide member 32 and the insert plate 34, thereby reducing the movement error and improving the driving accuracy of the driving tooth 344 on the movable jaw 24, so as to achieve the synchronization of the movements of each jaw assembly 20, and the achieved driving effect can be kept consistent, which also promotes the improvement of the working efficiency of the jaw mechanism 100; wherein the fixed jaw 22 is fixed on the base 10, thereby being able to improve the positioning accuracy of the material, so that the movable jaw 24 can clamp or release the material more efficiently and reliably when it moves, further improving the working efficiency and reliability of the jaw mechanism 100.

[0056] As another example, see Figure 4 The clamping mechanism 100 also includes a second elastic member 12, which is elastically compressed and arranged between the base 10 and the strip seat 320. The second elastic member 12 is used to provide elastic force. When the strip seat 320 moves downward, the second elastic member 12 is compressed. After the force applied to the strip seat 320 is removed, the elastic force provided by the second elastic member 12 will drive the strip seat 320 to rise, and then drive the plug plate 34 to rise, so that the guide member 32 and the plug plate 34 are reset when the external driving force is removed, and the guide member 32 and the plug plate 34 can be automatically raised, thereby realizing the automatic clamping of the material by the clamping assembly 20. The second elastic member 12 can be a compression spring or an elastic sleeve. Among them, multiple second elastic members 12 can be arranged between the base 10 and the strip seat 320 to form a multi-point elastic support together, so as to provide a more stable support for the strip seat 320, so that the strip seat 320 can rise smoothly.

[0057] In this embodiment, the clamp mechanism 100 further includes a pusher 14, which is located on the side of the bar seat 320 away from the base 10 and is used to drive the bar seat 320 to move downward. There is at least one pusher 14, for example, two pushers 14, which are respectively located at both ends of the bar seat 320 and are used together to drive the bar seat 320 to move downward steadily and smoothly. Optionally, a driving actuator such as a cylinder may be provided to drive the pusher 14 to move so as to drive the bar seat 320 to move downward.

[0058] As another embodiment, there are multiple clamping jaws 20, and the clamping jaw mechanism further includes a base 10, and multiple fixed clamping jaws 22 are connected to the base 10 in a row, and the multiple fixed clamping jaws 22 are flush with each other; wherein the multiple fixed clamping jaws 22 are integrally formed, thereby reducing assembly errors, improving the processing accuracy of the fixed clamping jaws, and thus improving the positioning accuracy when the welding strip 105 is clamped, and the cost can also be reduced. Furthermore, the multiple fixed clamping jaws 22 are connected together by a connecting piece, and the multiple fixed clamping jaws 22 are integrally formed with the connecting piece and then installed on the base 10.

[0059] As another embodiment, there is no gap between the first reference plane 223 and the third reference plane 245, and the end of the movable jaw 24 for clamping the welding strip 105 is provided with an avoidance space for part of the fixed jaw 22 to pass through (not shown in the figure, the avoidance space is in the middle of the movable jaw 24). By setting the first reference plane 223 and the third reference plane 245 to have no gap, the welding strip will not be stuck in a position other than the position for clamping and transporting the welding strip between the movable jaw 24 and the fixed jaw 22. Furthermore, in order to prevent the first reference plane 223 from blocking the movable jaw 24, an avoidance space for part of the fixed jaw (the part of the end for clamping the welding strip corresponding to the first reference plane 223) to pass through is provided at the end of the movable jaw 24 for clamping the welding strip.

[0060] As another embodiment, the end of the fixed clamping jaw 22 for clamping the welding strip further includes a protruding portion protruding downward relative to the second reference surface 224, and the protruding portion includes a blocking reference surface 225 arranged opposite to the first reference surface 223, and the blocking reference surface 225 is used to prevent the welding strip from being taken away by the passive clamping jaw 24 when the clamping jaw assembly 20 releases the welding strip, and the avoidance space is also used for the protruding portion to pass through.
