[0027] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0028] As described in the background art, currently when conducting a high temperature resistance test on a wire, it is usually necessary to manually press the wire onto a platform to ensure that the wire sample fits the heating platform. However, this method is too labor-intensive and inefficient, and there is also a risk of burns.

[0029] Therefore, the embodiment of the present application creatively proposes a straightening device for wire and a heating device thereof. The straightening device for wire includes a straightening component and a moving component. The straightening component includes a bracket and at least two clamps connected to the bracket. When performing a high temperature resistance test on the wire, the clamps are first used to clamp the two ends of the wire sample respectively, and then the clamps at the two ends of the wire sample are moved relative to the bracket to move away from each other, thereby straightening the wire sample to meet the test requirements, and then the bracket is driven close to the heating platform by the moving component, so that the straightened wire sample fits the heating platform. After the test is completed, the bracket is driven away from the heating platform by the moving component. Compared with the prior art, the present application can efficiently straighten the wire sample through the clamp, and at the same time, there is no human intervention in the process of heating the wire sample, thereby avoiding the occurrence of dangers such as burns.

[0030] The present invention will be described in detail below through specific embodiments.

[0031] Example 1

[0032] Reference Figures 1 to 3 As shown, an embodiment of the present application provides a straightening device for a wire, which includes a straightening component 1 and a moving component 2. The straightening component 1 includes a bracket 11 and at least two clamps 12 connected to the bracket 11, the clamps 12 are configured to clamp a wire sample 4, and can move relative to the bracket 11 to straighten the wire sample 4; the moving component 2 is connected to the bracket 11 to drive the bracket 11 to approach or move away from the heating platform 3, thereby making the straightened wire sample 4 fit onto or detach from the heating platform 3.

[0033] It is understandable that the wire sample 4 refers to a portion of the wire cut during or after the production process according to the process requirements. In some cases, straightening the wire sample 4 also includes slightly stretching the wire sample 4 to ensure that the wire sample 4 fits the heating platform 3. In this embodiment, the bracket 11 is in the shape of a rectangular parallelepiped as a whole.

[0034] In addition, the straightening component 1 in the present application can also be used to straighten some materials with regular or irregular shapes, such as braided hemp ropes.

[0035] It should be noted that, in actual operation, the corresponding number of clamps 12 can be selected according to factors such as the length and width of the wire sample 4. In this embodiment, two clamps 12 are selected to clamp the wire; of course, three, four or more clamps 12 can also be selected to clamp the wire. In addition, the position of the clamp 12 clamping the wire sample 4 needs to be determined according to the actual test conditions. In this embodiment, the length of the wire sample 4 is set to be slightly larger than the length to be heated, so the clamp 12 needs to clamp both ends of the wire sample 4.

[0036] Specifically, when conducting a high temperature resistance test on a wire, firstly, two clamps 12 are used to clamp the two ends of the wire sample 4 respectively, and then the two clamps 12 are moved relative to the bracket 11 to move the two away from each other, thereby straightening the wire sample 4 until the test requirements are met; then the moving component 2 is used to drive the bracket 11 close to the heating platform 3 until the straightened wire sample 4 is attached to the heating platform 3; after heating the wire sample 4 for a certain period of time, the moving component 2 is used to drive the bracket 11 away from the heating platform 3 until the wire sample 4 is separated from the heating platform 3. Figure 2 As shown, as an example but not limitation, the clamping member 12 includes a base 121 and at least one adjusting member 122, and the adjusting member 122 is connected to a lockable movable connection to cooperate with at least one of the base 121 or other adjusting members 122 to clamp or release the wire sample 4.

[0037] Among them, the lockable movable connection includes a pin connection, a threaded connection, a clamping shaft connection, etc. The clamping shaft connection includes a clamping spring and a clamping shaft, and the clamping shaft is inserted in the base 121 so that it can move relative to the base 121. When moving to the target position, the clamping spring is added to prevent the clamping shaft from moving axially.

[0038] In this embodiment, the adjusting member 122 is threadedly connected to the base 121 .

[0039] It should be noted that when the wire sample 4 is moved close to the heating platform 3, the wire sample 4 can be close to the heating platform 3 in the height direction, width direction or length direction of the heating platform 3, and the specific needs need to be adjusted according to the specific position of the heating surface of the heating platform 3.

[0040] Furthermore, in some examples, the base 121 has a receiving groove 1211 for allowing part of the wire sample 4 to enter and exit, and the adjusting member 122 has an abutting end 1221 that can extend into the receiving groove 1211, so that when the clamping member 12 clamps the wire sample 4, the base 121 or at least one adjusting member 122 supports the wire sample 4.

[0041] It should be noted that when clamping the wire sample 4, the adjusting member 122 can cooperate with the base 121 to clamp the wire sample 4, or can cooperate with another adjusting member 122 to clamp the wire sample 4; or three or more adjusting members 122 can cooperate to clamp the wire sample 4.

[0042] As an example but not limitation, the clamping member 12 includes at least two adjusting members 122 arranged opposite to each other to form a variable clamping space 1212 in the receiving groove 1211 , so as to clamp or release the wire sample 4 .

[0043] In this embodiment, one clamping member 12 includes two adjusting members 122 arranged opposite to each other to clamp or release the wire sample 4. Specifically, the two adjusting members 122 are arranged in sequence along their own axial direction.

[0044] In addition, in some examples, the adjusting member 122 is threadedly connected to the base 121 to drive the abutting end 1221 to move in the receiving groove 1211 .

[0045] Reference Figure 2 As shown, as an example but not limitation, the adjusting member 122 is in the shape of a stepped shaft as a whole, and includes an abutting end 1221, a middle portion 1222 and a rotating portion 1223 which are sequentially distributed along its own axial direction and integrally formed, the abutting end 1221 extends into the receiving groove 1211, the middle portion 1222 is threadedly connected to the base 121, and the rotating portion 1223 is located above the base 121. When adjusting the position of the abutting end 1221, the rotating portion 1223 can be driven to rotate manually or by a micro motor, so that the abutting end 1221 moves in the receiving groove 1211 along the axial direction of the adjusting member 122.

[0046] Specifically, when clamping the wire sample 4, first place the end of the wire on the abutment end 1221 of the lower adjustment member 122, and then adjust the upper adjustment member 122 to make the abutment end 1221 of the upper adjustment member 122 gradually approach the lower abutment end 1221 until the two abutment ends 1221 clamp the wire sample 4 together. Of course, the lower abutment end 1221 can be adjusted alone to make the wire sample 4 gradually approach the upper abutment end 1221; or the upper and lower abutment ends 1221 can be adjusted at the same time, so as to achieve rapid clamping of the wire sample 4.

[0047] In some examples, a clamping surface adapted to the wire sample 4 is provided on the side of the abutting end 1221 facing the wire sample 4 , and an anti-slip pattern is provided on the clamping surface to improve the clamping stability of the wire sample 4 .

[0048] It should be noted that the clamp 12 can be directly disposed on the bracket 11, or disposed on the bracket 11 through other components. In some examples, the clamp 12 is connected to the bracket 11 through a multi-axis robotic arm, and the wire sample 4 can be straightened by moving the multi-axis robotic arm in the corresponding direction.

[0049] In some examples, reference Figure 1 and Figure 3 As shown, at least two sliding platforms 5 are disposed on the bracket 11 , and the sliding platforms 5 are connected to the bases 121 of the corresponding clamping members 12 to drive the clamping members 12 to slide relative to the bracket 11 .

[0050] Furthermore, in some examples, a sliding member is provided on the bracket 11 , and the sliding member is connected to the sliding platform 5 to drive the sliding platform 5 to slide relative to the bracket 11 .

[0051] In this embodiment, the sliding platform 5 is a manual linear slide, so that the user can use the sliding platform 5 to straighten the wire sample 4 for a short distance; the sliding member is a double-slider slide rail module, which can be set as a self-contained drive member, so that the two sliding platforms 5 can be quickly moved closer or farther away, so as to quickly straighten the wire sample 4 to the state required by the test; if the wire sample 4 is long, the two sliding platforms 5 can be first moved closer by the sliding member, so that the two ends of the wire sample 4 can be placed at the corresponding clamping members 12 manually or by a manipulator, thereby improving the clamping efficiency. Usually, the straightening lengths required for the wire samples 4 of the same batch are relatively close. At this time, the two sliding platforms 5 can be quickly adjusted by the sliding member, so that after the two clamping members 12 clamp the wire sample 4, the wire sample 4 is straightened or nearly straightened. Then, the sliding platform 5 is manually adjusted to perform fine-tuning to straighten the wire sample 4 to the state required by the test.

[0052] It can be understood that the heating surface on the heating platform 3 for direct contact with the wire sample 4 is matched with the length of the wire sample 4. When encountering wire samples 4 of different lengths, the wire sample 4 can be adapted by replacing the heating platform 3 or adjusting the size of the heating surface of the heating platform 3.

[0053] The method of observing the wire sample 4 includes manual observation, detection element observation or a combination of the two.

[0054] In some examples, the detection element observation method can set a detection camera on the top and front or back side of the wire sample 4 to obtain the surface undulation state of the clamped wire sample 4, so as to control the distance between the two clamps 12, thereby maintaining or changing the straightening state of the wire sample 4; or only one multi-axis motion detection camera can be set to shoot different sides of the wire sample 4, so as to obtain the surface undulation state of the clamped wire sample 4, so as to adjust the distance between the two clamps 12, thereby maintaining or changing the straightening state of the wire sample 4.

[0055] In some examples, limit switches may be provided only at both ends of the bracket 11 to control the relative movement distance between the two clamps 12, so that the wire sample 4 can be quickly straightened when the length of the wire sample 4 and the length of the wire sample 4 under the test state are known.

[0056] In some examples, reference Figure 1 As shown, the moving assembly 2 includes a translation member 21 and a lifting member 22. The translation member 21 is used to drive the bracket 11 to move in the horizontal direction, and the lifting member 22 is used to drive the bracket 11 to move in the vertical direction.

[0057] In this embodiment, the fixed end of the lifting member 22 is connected to the moving end of the translation member 21, and the bracket 11 is connected to the moving end of the lifting member 22. Specifically, when the wire sample 4 is straightened to meet the test requirements, the bracket 11 is moved by the lifting member 22 and the translation member 21, so that the wire sample 4 gradually approaches the heating platform 3 until the wire sample 4 is in contact with the heating surface of the heating platform 3.

[0058] It can be understood that the fixed end refers to the structure in the component that remains relatively still (in this embodiment, the bracket 11 is used as the reference coordinate), such as the slide rail and other components; the moving end refers to the structure in the component that can produce relative movement, such as the slider and other components.

[0059] In this embodiment, the translation member 21 is a rodless cylinder, and the lifting member 22 is a linear slide rail assembly. Of course, the translation member 21 and the lifting member 22 can also be other components that can realize linear drive.

[0060] In some examples, a pulley assembly may be provided below the moving assembly 2 to facilitate rapid movement of the wire straightening device to the corresponding heating platform 3 .

[0061] Example 2

[0062] Corresponding to the above embodiment 1, refer to Figure 3 As shown, an embodiment of the present application further provides a heating device, comprising the wire straightening device as described above and a heating platform 3 , wherein the heating platform 3 is configured to heat a wire sample 4 .

[0063] In some examples, the heating platform 3 is generally in the shape of a cube, and its heating surface is the plane on the top of the heating platform 3, which can support the wire sample 4 and facilitate the fitting of the wire sample 4 and the heating surface. Of course, the heating surface of the heating platform 3 can also be other sides of the wire, such as the front side or the left side.

[0064] It should be noted that, in this embodiment, when clamping the wire sample 4, the clamping surfaces at the bottom of the two clamps 12 can be adjusted to the same horizontal height in advance so that they remain parallel to the heating surface of the heating platform 3, thereby facilitating the wire sample 4 to fit onto the heating platform 3.

[0065] In some examples, a roller assembly may be further provided at the bottom of the heating platform 3 to facilitate the user to quickly adjust the position of the heating platform 3 .
