Description

Technical Field

[0001] This utility model relates to the field of photovoltaic ribbon manufacturing technology, and in particular to a wire straightening device and its heating device. Background Technology

[0002] In the production and manufacturing process of photovoltaic welding ribbons, it is often necessary to test the performance of the wires. For example, during the production process, a sample of the wires is taken out and subjected to a high-temperature resistance test to observe how long it takes for the wires to turn yellow or black under high temperatures.

[0003] Currently, heating equipment typically includes a separate heating platform. When heating wire, workers place the wire sample on the platform. However, because some types of wire are easily bent, it's difficult to achieve proper contact between the sample and the heating platform during heating, resulting in ineffective heating. Some manufacturers manually press the wire onto the platform, but this method is not only inefficient but also poses risks such as burns. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wire straightening device and a heating device to solve the problem in the prior art that easily warped wire samples cannot be safely and effectively adhered to the heating platform.

[0006] A straightening assembly, the straightening assembly including a support and at least two clamping members connected to the support, the clamping members being configured to clamp a wire sample and being movable relative to the support to straighten the wire sample;

[0007] A movable component, connected to the support, drives the support to move closer to or away from the heating platform, thereby causing the straightened wire sample to adhere to or detach from the heating platform.

[0008] Based on the above-described wire straightening device, the two ends of the wire sample are first clamped by clamping components. Then, the clamping components at both ends of the wire sample are moved away from the support to straighten the wire sample to meet the test requirements. Next, a moving component moves the support closer to the heating platform in a preset direction, causing the straightened wire sample to adhere to the heating platform. After the test is completed, the moving component moves the support away from the heating platform. Compared to existing technologies, this application can efficiently straighten wire samples using clamping components, and no manual intervention is required during the heating process, avoiding the risk of burns.

[0009] In one embodiment of the above-described wire straightening device, the clamping member includes a base and at least one adjusting member, the adjusting member being lockably connected to the base to cooperate with the base or at least one of the other adjusting members to clamp or release the wire sample.

[0010] In one embodiment of the above-described wire straightening device, the base has a receiving groove for a portion of the wire sample to enter and exit, and the adjusting member has an abutment end that can extend into the receiving groove so that when the clamping member clamps the wire sample, the base or at least one of the adjusting members carries the wire sample.

[0011] In one embodiment of the above-mentioned wire straightening device, the side of the abutting end facing the wire sample is provided with a clamping surface adapted to the wire sample, and the clamping surface is provided with anti-slip texture.

[0012] In one embodiment of the wire straightening device described above, the clamping member includes at least two opposing adjusting members to form a variable clamping space within the receiving groove, thereby clamping or releasing the wire sample.

The translation component is used to drive the support to move in the horizontal direction, and the lifting component is used to drive the support to move in the vertical direction.

[0017] In a second aspect, the present invention also provides a heating device, comprising the wire straightening device and the heating platform described above, wherein the heating platform is configured to heat the wire sample.

[0018] The above-described one or more embodiments of this utility model have at least one or more of the following beneficial effects:

[0019] In conducting high-temperature resistance tests on wire samples, the two ends of the wire sample are first clamped using clamping devices. Then, the clamping devices at both ends are moved away from the support frame to straighten the wire sample to meet the test requirements.

[0027] Some embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0028] As described in the background section, currently, when conducting high-temperature resistance tests on wires, it is usually necessary to manually press the wire onto a platform to ensure that the wire sample adheres to the heating platform. However, this method is too labor-intensive and inefficient, and also carries risks such as burns.

[0029] Therefore, this application creatively proposes a wire straightening device and its heating device. The wire straightening device includes a straightening component and a moving component. The straightening component includes a support and at least two clamping members connected to the support. During the high-temperature resistance test of the wire, the clamping members first clamp both ends of the wire sample. Then, the clamping members clamping the two ends of the wire sample are moved relative to the support to move away from each other, thereby straightening the wire sample to meet the test requirements. Then, the moving component moves the support closer to the heating platform, so that the straightened wire sample adheres to the heating platform. After the test is completed, the moving component moves the support away from the heating platform. Compared with the prior art, this application can efficiently straighten wire samples using the clamping members, and at the same time, no manual intervention is required during the heating process of the wire sample, avoiding the danger of burns.

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

[0031] Example 1

[0032] Reference Figures 1 to 3 As shown in the figure, this application provides a wire straightening device, which includes a straightening component 1 and a moving component 2. The straightening component 1 includes a support 11 and at least two clamping members 12 connected to the support 11. The clamping members 12 are configured to clamp a wire sample 4 and can move relative to the support 11 to straighten the wire sample 4. The moving component 2 is connected to the support 11 to drive the support 11 to move closer to or away from the heating platform 3, thereby causing the straightened wire sample 4 to adhere to or detach from the heating platform 3.

[0033] It is understood that wire sample 4 refers to a portion of the wire cut during or after production, as required by the process. In some cases, straightening the wire sample 4 may also involve slightly stretching it to ensure that it adheres to the heating platform 3. In this embodiment, the support 11 is generally rectangular.

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

[0035] It should be noted that in actual operation, the appropriate number of clamping members 12 can be selected based on factors such as the length and width of the wire sample 4. In this embodiment, two clamping members 12 are selected to clamp the wire; of course, three, four, or more clamping members 12 can also be selected to clamp the wire. In addition, the position of the clamping members 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 clamping members 12 need to clamp both ends of the wire sample 4.

[0036] Specifically, during the high-temperature resistance test of the wire, firstly, two clamping pieces 12 are used to clamp both ends of the wire sample 4. Then, the two clamping pieces 12 are moved relative to the support 11 to move them away from each other, thereby straightening the wire sample 4 until the required test conditions are met. Next, the moving component 2 is used to drive the support 11 closer to the heating platform 3 until the straightened wire sample 4 adheres 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 support 11 away from the heating platform 3 until the wire sample 4 detaches from the heating platform 3. (Refer to...) Figure 2 As shown, by way of example and not limitation, the clamp 12 includes a base 121 and at least one adjusting member 122, the adjusting member 122 being lockably movable to engage with at least one of the base 121 or other adjusting members 122 to clamp or release the wire sample 4.

[0037] The lockable movable connections include pin connections, threaded connections, and snap-fit ​​connections. The snap-fit ​​connection includes a snap ring and a snap-fit. The snap-fit ​​is inserted into the base 121, allowing it to move relative to the base 121. When it moves to the target position, a snap ring is installed to prevent the snap-fit ​​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 moving the wire sample 4 close to the heating platform 3, the wire sample 4 can approach the heating platform 3 in the height direction, width direction or length direction, depending on 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 partial wire sample 4 to enter and exit, and the adjusting member 122 has an abutment end 1221 that can extend into the receiving groove 1211 so that the base 121 or at least one adjusting member 122 carries the wire sample 4 when the clamping member 12 clamps 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 it 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 and not a limitation, the clamping member 12 includes at least two opposing adjustment members 122 to form a variable clamping space 1212 within the receiving groove 1211, thereby clamping or releasing the wire sample 4.

[0043] In this embodiment, a clamping member 12 includes two opposing adjusting members 122 to clamp or release the wire sample 4. Specifically, the two adjusting members 122 are arranged sequentially along their own axial direction.

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

[0045] Reference Figure 2 As shown, and not as a limitation, the adjusting member 122 is generally stepped shaft-shaped, comprising an abutment end 1221, a middle portion 1222, and a rotating portion 1223, which are sequentially distributed and integrally formed along its own axial direction. The abutment 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 abutment end 1221, the rotating portion 1223 can be rotated manually or by a micro motor, thereby causing the abutment end 1221 to move along the axial direction of the adjusting member 122 within the receiving groove 1211.

[0046] Specifically, when clamping the wire sample 4, first place the end of the wire on the abutment end 1221 of the lower adjusting member 122, and then adjust the upper adjusting member 122 so that the abutment end 1221 of the upper adjusting member 122 gradually moves closer to the lower abutment end 1221 until both 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 move closer to the upper abutment end 1221; or the upper and lower abutment ends 1221 can be adjusted simultaneously to achieve rapid clamping of the wire sample 4.

[0047] In some examples, the abutment end 1221 has a clamping surface adapted to the wire sample 4 on the side facing the wire sample 4, and the clamping surface has anti-slip texture, thereby improving the clamping stability of the wire sample 4.

[0048] It should be noted that the clamping member 12 can be directly mounted on the support 11, or mounted on the support 11 through other components. In some examples, the clamping member 12 is connected to the support 11 through a multi-axis robotic arm, and the straightening of the wire sample 4 can be achieved by the movement of the multi-axis robotic arm in the corresponding direction.

[0049] In some examples, refer to Figure 1 and Figure 3 As shown, the bracket 11 is provided with at least two sliding platforms 5, and the sliding platforms 5 are connected to the base 121 of the corresponding clamping member 12 so as to drive the clamping member 12 to slide relative to the bracket 11.

[0050] Furthermore, in some examples, the bracket 11 is also provided with a slider, which 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, allowing the user to straighten the wire sample 4 over a short distance using the sliding platform 5. The sliding element is a double-slider slide rail module, which can be configured with a built-in drive component, allowing the two sliding platforms 5 to be moved closer or further apart quickly to pull the wire sample 4 to the required test state. If the wire sample 4 is long, the two sliding platforms 5 can be brought closer together using the sliding element, so that the two ends of the wire sample 4 can be placed at the corresponding clamping parts 12 manually or by a robotic arm, thereby improving clamping efficiency. Typically, the required straightening lengths of wire samples 4 in the same batch are similar. In this case, the two sliding platforms 5 can be quickly adjusted using the sliding element so that the wire sample 4 is straightened or nearly straightened after being clamped by the two clamping parts 12. Then, the sliding platforms 5 can be manually adjusted for fine-tuning to straighten the wire sample 4 to the required test state.

[0052] It can be understood that the heating surface on the heating platform 3, which is used to directly contact the wire sample 4, is matched to the length of the wire sample 4. When encountering wire samples 4 of different lengths, the heating platform 3 can be replaced or the size of the heating surface of the heating platform 3 can be adjusted to fit the wire sample 4.

[0053] Among them, the observation methods for wire sample 4 include manual observation, observation by detection elements, or a combination of both.

[0054] In some examples, the detection element observation method can be to set a detection camera on the top and front or rear 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 clamping members 12, thereby maintaining or changing the straightening state of the wire sample 4; or only a multi-axis motion detection camera can be set to take pictures of different sides of the wire sample 4 to obtain the surface undulation state of the clamped wire sample 4, so as to adjust the distance between the two clamping members 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 distance of relative movement between the two clamps 12, thereby allowing the wire sample 4 to be quickly straightened under the condition that the length of the wire sample 4 is known and the length of the wire sample 4 under test conditions is equal.

[0056] In some examples, refer to Figure 1 As shown, the moving component 2 includes a translation component 21 and a lifting component 22. The translation component 21 is used to drive the support 11 to move in the horizontal direction, and the lifting component 22 is used to drive the support 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 required to straighten during the test, 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 is understood that the fixed end refers to the structure in the component that remains relatively stationary (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 generate relative motion, such as the slider and other components.

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

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

[0061] Example 2

[0062] Corresponding to Embodiment 1 above, refer to Figure 3 As shown, this application embodiment also provides a heating device, including the wire straightening device as described above and a heating platform 3, the heating platform 3 being configured to heat the wire sample 4.

[0063] In some examples, the heating platform 3 is generally cubic in structure, with its heating surface being the flat top surface of the heating platform 3, which can support the wire sample 4 and facilitate the contact between 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 or left side.

[0064] It should be noted that, in this embodiment, when clamping the wire sample 4, the clamping surface of the lower clamping member 12 can be adjusted to the same horizontal height in advance so that it is parallel to the heating surface of the heating platform 3, thereby facilitating the wire sample 4 to fit into the heating platform 3.

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