Description

Technical Field

[0001] This application relates to the technical field of material clamping in automated production, and particularly to a method for clamping linear materials. Background Art

[0002] In the process of automated production, in order to improve production efficiency, linear materials usually need to be fed as a whole and then processed. How to clamp and fix linear materials is a technical problem that often exists in the prior art.

[0003] Chinese Patent, Patent No. CN201910812623.1 discloses a multi-core wire automatic and stable clamping device and its working method, including: a machine table bottom plate, a support block, and a clamping device. The clamping device is provided with a core wire guiding mechanism, a core wire clamping mechanism, a core wire end positioning mechanism, and a core wire automatic misalignment mechanism. The clamping device is arranged on the support block, and the core wire guiding mechanism, the core wire clamping mechanism, the core wire end positioning mechanism, and the core wire automatic misalignment mechanism are all arranged on the support block. The core wire clamping mechanism is arranged inside the core wire guiding mechanism, the core wire end positioning mechanism is arranged on the side of the core wire clamping mechanism away from the core wire guiding mechanism, and the core wire automatic misalignment mechanism is arranged behind the core wire end positioning mechanism and the two cooperate with each other; it also includes a pulling rod and a multi-core wire. The pulling rod is arranged outside the core wire automatic misalignment mechanism, and a chuck is arranged at the end of the pulling rod. The multi-core wire is arranged on one side of the core wire guiding mechanism. However, in this mechanism, the clamping action is completed as long as the core wire passes through the clamping device. In some scenarios, such as during the feeding process of the welding tape of a battery cell, usually multiple groups of welding tapes are fed simultaneously at one time, and the battery cell is relatively fixed. How to clamp the linear welding tape and then move it to the surface of the battery cell is currently quite difficult in this field. Therefore, there is an urgent need to provide a new method for clamping linear materials to solve the technical problems existing in the prior art. Summary of the Invention

[0004] The purpose of this application is to provide a method for clamping linear materials to solve the problem that it is difficult to achieve stable clamping of current linear materials during the production process.

[0005] The technical solution of the present invention is: a method for clamping linear materials, including configuring a clamping mechanism with a first clamping arm and a second clamping arm. The first clamping arm has a first clamping surface, and the second clamping arm has a second clamping surface. The second clamping arm includes a connecting portion and a clamping portion extending from the connecting portion towards the first clamping arm. The opposite end surface of the clamping portion and the first clamping surface is configured as the second clamping surface. A clamping space capable of clamping linear materials is provided between the first clamping surface and the second clamping surface;

[0006] The clamping method includes the following steps:

[0007] S1: In the initial state, both the first clamping arm and the second clamping arm are arranged on the same side of the linear material, the first clamping surface faces the linear material, and the second clamping surface faces away from the linear material.

[0008] S2: The second clamping arm moves along a first path until the second clamping surface faces the linear material, such that the first clamping surface and the second clamping surface are arranged oppositely, and the vertical distance between the first clamping surface and the second clamping surface is greater than the height of the linear material.

[0009] S3: The second clamping arm approaches the linear material along a second path intersecting the first path, and places the linear material within the clamping space formed by the first clamping surface and the second clamping surface.

[0010] S4: The first clamping arm and the second clamping arm move towards each other, such that the first clamping surface and the second clamping surface respectively abut against the linear material and apply a clamping force to the linear material.

[0011] Preferably, in step S2, when the second clamping arm moves along the first path until the second clamping surface faces the linear material, the first clamping arm simultaneously moves along the first path towards the linear material to shorten the distance between the first clamping surface and the linear material.

[0012] Preferably, after the first clamping arm simultaneously moves along the first path towards the linear material, the second clamping arm and the first clamping arm simultaneously approach the linear material along the second path intersecting the first path.

[0013] Preferably, the first clamping surface is arranged on the end surface of the first clamping portion opposite to the second clamping surface.

[0014] Preferably, in step S4, multiple clamping mechanisms apply a clamping force to the linear material. The number of clamping mechanisms is not less than the number of linear materials, and the sum of the width L1 of the connecting portion and the width L2 of the clamping portion is less than the space distance L3 between adjacent linear materials.

[0015] Preferably, the width L2 of the clamping portion is not less than 1 / 2 of the diameter of the cylindrical linear material.

[0016] Preferably, the method for the second clamping arm to approach the linear material along the second path intersecting the first path includes driving the second clamping arm to move along the second path by a first driving mechanism.

[0017] Preferably, the manner in which the first clamping surface and the second clamping surface respectively abut against the linear material includes that after the first driving mechanism drives the second clamping arm to approach the linear material along the second path, the first driving mechanism continues to drive the second clamping arm and the first clamping arm to move towards each other and then clamp the linear material.

[0018] Preferably, the method for the second clamping arm to move along the first path includes driving the second clamping arm to move along the first path through a second driving mechanism.

[0019] Preferably, the process of the second clamping arm moving along the second path includes a process of avoiding the linear material.

[0020] Compared with the prior art, the advantages of this application are:

[0021] (1) In the process of clamping linear materials, when the occupied space of the equipment is limited, a highly efficient and precise clamping method is reasonably designed. For multiple groups of long strip-shaped materials, it can not only effectively clamp them simultaneously, but also reduce the occupied space of the equipment, and the clamping is stable and reliable.

[0022] (2) When multiple groups of linear materials need to be clamped simultaneously and the distance between the materials is small, the designed clamping method is efficient and reasonable in operation. There is no interference between each clamping mechanism and multiple groups of linear materials during movement, and it has a relatively reasonable movement rhythm.

[0023] (3) The first clamping arm and the second clamping arm are designed as a clamping mechanism that can move simultaneously. Through a set of driving mechanisms, the first clamping arm and the second clamping arm are respectively driven to move along different paths in two different directions. The movement path is ingeniously designed and occupies the smallest space.

[0024] (4) In the working scenario where clamping can only be performed after multiple groups of linear materials move to the designated position, since the next production station needs to be arranged in the length direction of the linear material, the clamping mechanism can only be configured in the height direction of the linear material. By adopting the method provided in this embodiment, there is no need to configure the clamping mechanism in the length direction of the linear material, and the clamping rhythm in the height direction is small, the time used is short, and the clamping stability is stronger.

[0036] Embodiment 1:

[0037] As shown Figure 1-2 in the figure, a method for clamping a linear material mainly uses a clamping mechanism 1 to clamp the linear material. Among them, the clamping mechanism 1 includes a first clamping arm 11 and a second clamping arm 12. The first clamping arm 11 and the second clamping arm 12 can move towards each other to provide a clamping force for the material to be clamped. The second clamping arm 12 is L-shaped as a whole, including a connecting portion 121 arranged longitudinally. A clamping portion 122 extends from the connecting portion 121 towards the first clamping arm 11. A first clamping surface 11A is arranged on the end surface of the first clamping arm 11, and a second clamping surface 12A is arranged on the end surface of the clamping portion 122. A clamping space 13 for clamping the linear material is arranged between the first clamping surface 11A and the second clamping surface 12A.

[0038] Based on the above clamping mechanism 1, in one embodiment, combined with Figure 1-3 as shown

[0039] S1: In the initial state, both the first clamping arm 11 and the second clamping arm 12 are arranged on the same side of the linear material 14. The first clamping surface 11A of the first clamping arm 11 faces the linear material 14, and the second clamping surface 12A of the second clamping arm 12 faces away from the linear material 14.

[0040] Specifically, in the case of feeding multiple groups of linear materials 14 at the same time, in order to ensure sufficient space for the battery cells during production, the initial position of the clamping mechanism 1 is above the linear material 14. At this time, the clamping space 13 is also correspondingly set above the linear material. In this state, it is impossible to clamp the material.

[0041] S2: The second clamping arm 12 moves along a first path to make the second clamping surface 12A face the linear material 14, so that the first clamping surface 11A and the second clamping surface 12A are arranged opposite to each other, and the vertical distance between the first clamping surface 11A and the second clamping surface 12A is greater than the height of the linear material 14.

[0042] Specifically, in this step, in order to enable the linear material 14 to be within the range of the clamping space 13, the second clamping arm 12 is moved along the first path, so that the first clamping surface 11A and the second clamping surface 12A can be arranged opposite to each other and are respectively located on both sides of the linear material. However, at this time, the linear material is not within the clamping space 13. In this embodiment, the first path is a longitudinal movement from top to bottom. In addition, the second clamping arm 12 can also move along the second path to avoid the linear material 14 and move to the second clamping surface 12A. For example, first move horizontally to one side of the linear material 14 to avoid interference with the linear material 14 in the longitudinal direction, and then move along the first path to make the first clamping surface 11A and the second clamping surface 12A in a relative state.

[0043] To drive the second clamping arm 12 to move along the first path, this embodiment provides a set of material clamping devices. The movement of the second clamping arm 12 is realized by setting the first driving structure 15. The second clamping arm 12 is installed on the first driving mechanism 15 that can realize reciprocating movement in the vertical direction. The first driving mechanism 15 can be a device that provides power such as a motor or a cylinder. Through the reciprocating movement of the first driving mechanism 15 in the vertical direction, the second clamping arm 12 is driven to move along the first path.

[0044] S3: The second clamping arm 12 approaches the linear material 14 along the second path that intersects the first path, and places the linear material 14 in the clamping space 13 formed by the first clamping surface 11A and the second clamping surface 12A.

[0045] In this embodiment, after the first clamping surface 11A and the second clamping surface 12A are in a relative state, the linear material 14 has not yet entered the clamping space 13. Therefore, it is necessary to further move the second clamping arm 12 closer to the linear material so that the linear material can enter the clamping space. At this time, the second clamping arm 12 approaches the linear material along the second path. In this embodiment, the second path is a horizontal lateral movement. At this time, the clamping portion 122 extending from the connecting portion 121 of the L-shaped second clamping arm 12 in the direction close to the first clamping arm 11 is moved below the linear material 14. Thus, the linear material 14 is arranged in the clamping space 13 formed between the first clamping surface 11A and the second clamping surface 12A.

[0046] To drive the second clamping arm 12 to approach the linear material 14 in the second direction, this embodiment sets a second driving mechanism 16. The second driving mechanism 16 is arranged on the first driving mechanism 15 and can be driven by the first driving mechanism 15 to reciprocate in the vertical direction. When the second clamping arm 12 moves to a specified position in the vertical direction, the second driving mechanism 16 drives the second clamping arm 12 to approach the linear material 14. The second driving mechanism 16 can be a device that provides power such as a motor or a cylinder.

[0047] S4: The first clamping arm 11 and the second clamping arm 12 move towards each other, so that the first clamping surface 11A and the second clamping surface 12A respectively abut against the linear material 14, and apply a clamping force to the linear material 14.

[0048] Specifically, after the linear material 14 enters the clamping space, by continuing to apply a force for the first clamping part 11 and the second clamping part 12 to move towards each other, clamping of the linear material 14 can be achieved.

[0049] The second driving mechanism 16 provided in this embodiment can not only drive the second clamping arm 12 to approach the linear material 14 along the second direction, but also provide power for the first clamping arm 11 and the second clamping arm 12 to move towards each other through the cooperation of the driving motor and the cam mechanism in the second driving mechanism 16, thereby clamping the linear material 14.

[0050] As Figure 4 shown, when designing multiple sets of clamping mechanisms 1 to apply clamping forces to the linear material 14 at the same time, the number of the clamping mechanisms 1 is not less than the number of the linear materials 14, and the sum of the width L1 of the connecting part 121 and the width L2 of the clamping part 122 is less than the space distance L3 between adjacent linear materials 14, thereby ensuring that when there are multiple sets of linear materials, each clamping structure can accurately clamp each group of linear materials without interference.

[0051] And when clamping a cylindrical linear material, the width L2 of the clamping part 122 is not less than 1 / 2 of the diameter of the cylindrical linear material 14. Thus, the clamping part 122 can clamp both sides of the cylindrical linear material with a relatively small clamping surface in the width direction, and can reduce the overall size of the clamping mechanism 1 when multiple sets of clamping mechanisms 1 clamp the material 14.

[0052] Embodiment 2:

[0053] The difference between this embodiment and Embodiment 1 is that in the initial state, a clamping space 13 capable of clamping the linear material 14 has been configured between the first clamping arm 11 and the second clamping arm 12, and the clamping method is as follows:

[0054] As Figure 1 , 2 , 5 shown, S1: In the initial state, both the first clamping arm 11 and the second clamping arm 12 are arranged on the same side of the linear material 14, the first clamping surface 11A faces the linear material 14, the second clamping surface 12A faces away from the linear material 14, and a clamping space 13 for clamping the linear material 14 is configured between the first clamping arm 11 and the second clamping arm 12.

[0055] In this embodiment, a clamping mechanism 1 is assembled as a whole by movably assembling a first clamping arm 11 and the second clamping arm 12 in a preset assembly manner. A clamping space 13 is preset on the clamping mechanism 1. In the following steps, by simultaneously moving the first clamping arm 11 and the second clamping arm 12, the integration degree of the clamping mechanism can be higher.

[0056] S2: The first clamping arm 11 and the second clamping arm 12 simultaneously move along a first path until the second clamping surface 12A faces the linear material 14, so that the first clamping surface 11A and the second clamping surface 12A are arranged opposite to each other, and the distance between the first clamping surface 11A and the linear material 14 is shortened.

[0057] In this embodiment, the driving of the first driving mechanism 15 can drive the first clamping arm 11 and the second clamping arm 12 to reciprocate along the first path in the vertical direction, thereby realizing the process of simultaneously moving the first clamping arm 11 and the second clamping arm 12 along the first path. At this time, the first clamping arm 11 moves downward to shorten the distance between the first clamping surface 11A and the linear material 14, saving a certain amount of time for further clamping the linear material 14 in the next step.

[0058] S3: The first clamping arm 11 and the second clamping arm 12 simultaneously approach the linear material 14 along a second path intersecting the first path, and place the linear material 14 in the clamping space 13 formed by the first clamping surface 11A and the second clamping surface 12A.

[0059] As Figure 6 shown, in this embodiment, the first clamping arm 11 and the second clamping arm 12 are installed on a base 20. A second driving mechanism 16 is installed on the base 20. The second driving mechanism 16 can drive the first clamping arm 11 and the second clamping arm 12 to reciprocate along the second path. Specifically, a pushing component 17 is arranged at the output end of the second driving mechanism 16. The pushing component 17 is fixedly installed with the second clamping arm 12. When the second driving mechanism 16 drives the pushing component 17 to reciprocate along the second path, it drives the second clamping arm 12 to move synchronously with the first clamping arm 11, thereby realizing the action of simultaneously approaching the linear material 14 along the second path by the first clamping arm 11 and the second clamping arm 12. At this time, the linear material is already between the clamping spaces 13. Due to the integrated design of the first clamping arm 11 and the second clamping arm 12, during the lateral driving process, the assembled first clamping arm 11 and the second clamping arm 12 are also moved simultaneously without separate control, improving the accuracy of movement and making it more convenient to design the movement rhythm.

[0060] S4: The first clamping arm 11 and the second clamping arm 12 move towards each other, so that the first clamping surface 11A and the second clamping surface 12A respectively abut against the linear material 14, and apply a clamping force to the linear material (14).

[0061] In this embodiment, the first clamping arm 11 and the second clamping arm 12 can move towards each other by further driving of the second driving mechanism 16. Specifically, the pushing component 17 includes a guiding part 171 with at least a partial inclined surface. A stop part 18 is arranged on the second clamping arm 12. The end surface of the guiding part 171 can contact the end surface of the stop part 18. In this embodiment, the stop part 18 is a ball bearing. The second driving mechanism 16 drives the pushing component 17 to move along the second path. At this time, the inclined guiding part 171 can drive the stop part 18 to drive the first clamping arm 12 to move along the first path. Furthermore, when the second driving mechanism 16 can drive the pushing component 17 to cause a relative displacement between the guiding part 171 and the stop part 18, the first clamping arm 11 and the second clamping arm 12 can move towards each other, thereby driving the first clamping surface 11A and the second clamping surface 12A to respectively abut against the linear material 14, and realizing the clamping of the linear material 14.

[0062] In order to continuously and reciprocally drive the first clamping arm 11 and the second clamping arm 12 to move close to the linear material 14 along the second path and then continue to make the first clamping arm 11 and the second clamping arm 12 move towards each other to clamp the material, in this embodiment, an eccentric shaft 19 is arranged at the output end of the second driving mechanism 16. Through the continuous movement of the eccentric shaft 19 in the guiding mechanism, the pushing component 17 is driven to reciprocate in the second path. Furthermore, while realizing the reciprocating movement of the first clamping arm 11 and the second clamping arm 12 along the second path, the first clamping arm 11 and the second clamping arm 12 can also move towards each other to clamp the linear material 14 and reset.

[0063] The above embodiments are only for illustrating the technical concept and features of the present application, and the purpose is to enable those who are familiar with this technology to understand the content of the present application and implement it accordingly, and it cannot be used to limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present application is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present application.
