[0030] Electrode rods are a type of welding electrode. They can be used in resistance welding equipment, such as fixed spot welding machines, suspended spot welding machines, and robotic spot welding machines. Electrode rods are consumables for resistance spot welding guns and play a crucial role in the quality of welded joints.

[0031] The measurement of electrode rod size and taper cannot be quickly and effectively determined. After the electrode rod wears down, the meshing area with the electrode cap will decrease. During the welding process, the electrode cap will have insufficient biting force due to the reduced meshing area. The electrode cap will fall off during welding, affecting the welding quality and the operating rate of the production line.

[0032] Meanwhile, due to differences in the electrode rods produced by different manufacturers, wear and dimensional fluctuations during use can prevent them from fitting well with the electrode cap, which can easily lead to water leakage and even affect the welding strength. Currently, there is no dedicated testing tool for the electrode head of the electrode rod.

[0033] To address the technical problems existing in related technologies, this application provides an electrode rod detection device and detection system. The detection device can be equipped with a detection hole to facilitate the insertion of the electrode head of the electrode rod into the detection hole. The detection device can also be equipped with an observation area to observe the state of the electrode rod in the detection device, thereby assisting in determining whether the electrode head of the electrode rod meets expectations.

[0034] Specifically, this application provides a detection system, see [link to relevant documentation]. Figure 1 and Figure 2 , Figure 1This is a schematic diagram of the first embodiment of the detection system provided in this application; Figure 2 This is a schematic diagram of the second embodiment of the detection system provided in this application.

[0035] The detection system 1 includes an electrode rod 20 and an electrode rod detection device 10, which is used to detect the electrode rod 20. The electrode rod 20 may include an electrode head 21 and a cylindrical part. The electrode head 21 can be used to attach an electrode cap, thereby enabling welding operations on a specific object through the electrode rod 20 and the electrode cap. However, if the electrode head 21 and the electrode cap of the electrode rod 20 do not match, the electrode cap may easily detach from the electrode head 21 during the welding process. Therefore, it is necessary to detect the electrode head 21 of the electrode rod 20 by the electrode rod detection device 10 before use to determine whether the shape of the electrode rod 20 matches the electrode cap.

[0036] Furthermore, the electrode rod detection device 10 includes a detection body 100, which has a detection hole 110 for inserting the electrode head 21 of the electrode rod 20 along the axial direction X of the detection hole 110. The detection body 100 has an observation area 120 in the radial direction Y of the detection hole 110, which exposes the electrode head 21 located in the detection hole 110 in the radial direction Y. Figure 1 and Figure 2 As shown, the detection hole 110 can be a through hole or a blind hole. The shape of the inner wall of the detection hole 110 can match the shape of the outer wall of the electrode head 21, so that after the electrode head 21 is inserted into the detection hole 110, the outer wall of the electrode head 21 can fit against the inner wall of the detection hole 110. For example, when the outer wall of the electrode head 21 is conical, the inner wall of the detection hole 110 is also conical, or the outer wall of the electrode head 21 and the inner wall of the detection hole 110 are both spherical, etc. The electrode head 21 of the electrode rod 20 can be inserted into or withdrawn from the detection hole 110 along the axial direction X of the detection hole 110. When it is necessary to detect the shape of the electrode head 21, the electrode head 21 can be inserted into the detection hole 110, and the shape of the electrode head 21 can be judged by observing the insertion depth of the electrode head 21.

[0037] The outer wall of the detection body 100 can be cylindrical or cylindrical with a notch. For example, the detection body 100 can be an annular cylindrical structure. The detection body 100 has an observation area 120 in the radial direction Y of the detection hole 110. The observation area 120 allows the operator to observe the position of the electrode head 21 in the detection hole 110 from the outside of the detection body 100. When the shape of the outer wall of the electrode head 21 does not match the shape of the inner wall of the detection hole 110, the depth of the electrode head 21 inserted into the detection hole 110 may be too deep or too shallow. At this time, it can be determined that the shape of the electrode head 21 does not meet expectations. When the shape of the outer wall of the electrode head 21 matches the shape of the inner wall of the detection hole 110, the depth of the electrode head 21 inserted into the detection hole 110 is at a preset position. At this time, it can be determined that the shape of the electrode head 21 meets expectations. The observation area 120 may include, but is not limited to, a transparent area, an opening penetrating the side wall of the detection body 100, etc., and the radial direction Y of the detection hole 110 is perpendicular to the axial direction X of the detection body 100.

[0038] Through the above implementation method, the detection body 100 is provided with a detection hole 110, and the electrode head 21 of the electrode rod 20 can be inserted into the detection hole 110 along the circumferential direction of the detection hole 110, so that the electrode head 21 can be detected by the detection body 100. In addition, an observation area 120 is provided on the radial direction Y of the detection hole 110, so that the matching state between the electrode head 21 in the detection hole 110 and the detection hole 110 can be observed through the observation area 120, and then the electrode head 21 can be detected by the detection body 100, thereby reducing the occurrence of water leakage and poor welding due to the electrode head 21 not meeting the requirements during subsequent use.

[0039] See Figure 3 , Figure 3 This is a schematic diagram of the structure of the first embodiment of the electrode rod detection device provided in this application.

[0040] The observation area 120 penetrates the side wall of the detection body 100 along the radial direction Y. For example... Figure 3 As shown, the observation area 120 can be a through hole, penetrating the side wall of the detection body 100 in the radial direction Y, thereby allowing the detection hole 110 to be exposed through the observation area 120. The observation area 120 can also penetrate the two side surfaces of the detection body 100 in the axial direction X, thereby expanding the space exposed by the observation area 120 and enabling a more comprehensive observation of the position of the electrode head 21 in the detection hole 110.

[0041] Furthermore, at least a portion of the inner wall of the detection hole 110 is conical, and the taper of the detection hole 110 is between 1:9 and 1:20. The detection hole 110 may have a partially conical inner wall, or the entire detection hole 110 may be conical. The specific shape of the inner wall of the detection hole 110 can be set according to the shape of the outer wall of the electrode head 21. The taper of the detection hole 110 can be between 1:9 and 1:20, between 1:9.6 and 1:20, between 1:10 and 1:20, between 1:9.6 and 1:20, between 1:9 and 1:15, between 1:9 and 1:17, or between 1:9.6 and 1:15. Specifically, the taper of the detection hole 110 can be 1:9, 1:9.6, 1:10, 1:12, 1:14, 1:16, 1:18, 1:20, etc.

[0042] In some embodiments, the diameter of the opening of the detection hole 110 for insertion of the electrode head 21 is between 12 mm and 30 mm. The diameter of the opening of the detection hole 110 can be between 12 mm and 30 mm, between 15 mm and 30 mm, between 18 mm and 30 mm, between 12 mm and 25 mm, between 12 mm and 20 mm, between 20 mm and 30 mm, between 20 mm and 25 mm, etc. Specifically, the opening of the detection hole 110 can be 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, or 30 mm, etc.

[0043] In some embodiments, the size of the detection hole 110 in the axial direction X is between 50 mm and 80 mm. The size of the detection hole 110 in the axial direction X may also be between 50 mm and 80 mm, between 60 mm and 80 mm, between 55 mm and 80 mm, between 65 mm and 80 mm, between 50 mm and 75 mm, between 50 mm and 70 mm, between 50 mm and 65 mm, between 70 mm and 80 mm, between 70 mm and 75 mm, etc. Specifically, the size of the detection hole 110 in the axial direction X can be 50 mm, 55 mm, 65 mm, 70 mm, 75 mm, or 80 mm, etc.

[0044] See Figure 4 , Figure 4 This is a schematic diagram of the structure of the second embodiment of the electrode rod detection device provided in this application.

[0045] The observation area 120 is equipped with a standard reference area 130, which extends along the axial direction X. For example... Figure 4As shown, the position of the standard reference area 130 and its length extending along the axial direction X can be set according to actual conditions. The observation area 120 can penetrate the side wall of the detection body 100 along the radial direction Y. The standard reference area 130 can be located on the side wall of the observation area 120. The standard reference area 130 can be used to assist in determining the depth of the electrode head 21 inserted into the detection hole 110. For example, when the end of the electrode head 21 is located within the standard reference area 130, it can be determined that the shape of the electrode head 21 meets the expectation. When the end of the electrode head 21 is located outside the standard reference area 130, it can be determined that the shape of the electrode head 21 does not meet the expectation. The standard reference area 130 can also be provided with a scale to further determine the depth of the end of the electrode head 21 inserted into the detection hole 110.

[0046] Furthermore, the dimension of the standard reference area 130 in the axial direction X is greater than 0 and less than or equal to 1 mm. The dimension of the standard reference area 130 in the axial direction X can be greater than 0 and less than or equal to 0.9 mm, greater than 0 and less than or equal to 0.8 mm, greater than or equal to 0.1 and less than or equal to 0.9 mm, greater than or equal to 0.2 and less than or equal to 0.9 mm, greater than or equal to 0.3 and less than or equal to 0.8 mm, greater than or equal to 0.4 and less than or equal to 0.9 mm, greater than 0 and less than or equal to 0.7 mm, greater than 0 and less than or equal to 0.6 mm, greater than 0 and less than or equal to 0.5 mm, greater than 0 and less than or equal to 0.4 mm, greater than 0 and less than or equal to 0.3 mm, etc. Specifically, the dimensions of the standard reference area 130 in the axial direction X can be 0.1mm, 0.15mm, 0.2mm, 0.25mm, 0.3mm, 0.35mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, etc.

[0047] In some embodiments, the observation area 120 is further provided with two critical reference areas 140, and the standard reference area 130 is located between the two critical reference areas 140 in the axial direction X. Figure 4As shown, the position of the critical reference region 140 and its length extending along the axial direction X can be set according to actual conditions. The observation region 120 can penetrate the side wall of the detection body 100 along the radial direction Y. The critical reference region 140 can be located on the side wall of the observation region 120. The critical reference region 140 can be used to assist in determining the depth of the electrode head 21 inserted into the detection hole 110. The two critical reference regions 140 are located on both sides of the standard reference region 130 in the axial direction X. When the end of the electrode head 21 is located within the critical reference region 140, it can be determined that the shape of the electrode head 21 needs to be observed, or that the service life of the electrode head 21 is about to be exhausted. When the end of the electrode head 21 is located outside the critical reference region 140, it can be determined that the shape of the electrode head 21 does not meet expectations. The critical reference region 140 can also be provided with a scale to further determine the depth of the end of the electrode head 21 inserted into the detection hole 110.

[0048] Furthermore, the dimension of each critical reference region 140 in the axial direction X is greater than 0 and less than or equal to 0.25 mm. The dimension of the critical reference region 140 in the axial direction X can be greater than 0 and less than or equal to 0.25 mm, greater than 0 and less than or equal to 0.2 mm, greater than 0 and less than or equal to 0.15 mm, greater than 0 and less than or equal to 0.1 mm, greater than 0 and less than or equal to 0.05 mm, greater than or equal to 0.05 and less than or equal to 0.2 mm, greater than or equal to 0.05 and less than or equal to 0.175 mm, greater than or equal to 0.1 and less than or equal to 0.25 mm. Specifically, the dimension of the critical reference region 140 in the axial direction X can be 0.05 mm, 0.1 mm, 0.15 mm, 0.2 mm, 0.25 mm, etc.

[0049] In summary, the detection body 100 is provided with a detection hole 110, and the electrode head 21 of the electrode rod 20 can be inserted into the detection hole 110 along the circumferential direction of the detection hole 110, which facilitates the detection of the electrode head 21 by the detection body 100. In addition, an observation area 120 is provided on the radial direction Y of the detection hole 110, which can observe the matching state between the electrode head 21 and the detection hole 110 through the observation area 120, and then the electrode head 21 can be detected by the detection body 100, thereby reducing the occurrence of water leakage and poor soldering due to the electrode head 21 not meeting the requirements during subsequent use.
