[0013] In some embodiments, the radial dimension of the first rod segment is configured to avoid the observation area in the axial direction.
[0014] To address the aforementioned problems, this application provides a detection system comprising an electrode cap and an electrode cap detection device as described above, the electrode cap detection device being used to detect the electrode cap.
[0015] Compared with the prior art, the electrode cap testing device of this application includes a testing head and a rotating handle.

[0030] Electrode caps 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 caps are consumables for resistance spot welding guns and play a crucial role in the quality of welded joints.
[0031] Because electrode caps produced by different manufacturers still vary, they may not fit well with the electrode rod during use due to wear and dimensional fluctuations in processing, which can easily lead to water leakage and even affect the welding strength. Currently, there is no dedicated testing tool for the receiving hole of the electrode cap.
[0032] To address the technical problems existing in related technologies, this application also provides an electrode cap testing device and testing system. The testing head of the electrode cap testing device is inserted into the receiving hole of the electrode cap. Then, by rotating the testing head, the testing head rotates relative to the electrode cap in the receiving hole. An observation area is set on the testing head, which can observe the matching state between the testing head and the receiving hole in the receiving hole during the rotation of the testing head. In this way, the receiving hole can be tested by the testing head, reducing the risk of water leakage and poor soldering caused by the electrode cap not meeting the requirements in subsequent use.
[0033] Specifically, this application provides a detection system, see [link to relevant documentation]. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the first embodiment of the detection system provided in this application; Figure 2This is a schematic diagram of the second embodiment of the detection system provided in this application.
[0034] The detection system 1 includes an electrode cap 20 and an electrode cap detection device 10, which is used to detect the electrode cap 20. The electrode cap 20 may have a receiving hole 21 inside. The electrode cap 20 can be fitted onto an electrode rod, and then the electrode rod and electrode cap 20 work together to perform welding operations on a specific object. However, if the electrode head of the electrode rod and the electrode cap 20 do not match, the electrode cap 20 may easily detach from the electrode head during welding. Therefore, before use, the electrode cap detection device 10 needs to detect the receiving hole 21 of the electrode cap 20 to determine whether the shape of the electrode cap 20 matches the electrode rod. The shape of the electrode cap 20 can be set according to actual conditions. For example, the electrode cap 20 can be divided into a cylindrical part and a spherical part. The opening of the receiving hole 21 is located at one end of the cylindrical part, and the spherical part is located at the end of the cylindrical part opposite to the opening of the receiving hole 21.
[0035] Furthermore, the electrode cap detection device 10 includes a detection head 100 and a rotating handle 200. The rotating handle 200 is connected to one end of the detection head 100 in the axial direction X. The detection head 100 is used to be inserted into the receiving hole 21 of the electrode cap 20 in the axial direction X. The rotating handle 200 is used to drive the detection head 100 to rotate in the circumferential direction Z. The detection head 100 is provided with an observation area 110, which extends in the axial direction X to the end of the detection head 100 connected to the rotating handle 200. Figure 1 and Figure 2 As shown, the detection head 100 can be inserted into the receiving hole 21 of the electrode cap 20 along the axial direction X, or the detection head 100 can be withdrawn from the receiving hole 21 of the electrode cap 20 along the axial direction X. The shape of the inner wall of the receiving hole 21 can match the shape of the outer wall of the detection head 100, so that after the detection head 100 is inserted into the receiving hole 21, the outer wall of the detection head 100 can fit against the inner wall of the receiving hole 21. For example, when the outer wall of the detection head 100 is conical, the inner wall of the receiving hole 21 is also conical, or both the outer wall of the detection head 100 and the inner wall of the receiving hole 21 are spherical, etc. When it is necessary to detect the inner wall of the receiving hole 21 of the electrode cap 20, the detection head 100 can be inserted into the receiving hole 21 along the axial direction X, and the inner wall of the receiving hole 21 can be judged by observing information such as the depth of insertion of the detection head 100 into the receiving hole 21 to determine whether the inner wall of the receiving hole 21 meets the expectations.
[0036] The detection head 100 is provided with an observation area 110, which extends along the axial direction X to the end of the detection head 100 connected to the rotating handle 200. The observation area 110 allows the operator to observe the matching state between the detection head 100 and the receiving hole 21 from the outside of the receiving hole 21, thereby assisting in determining whether the shape of the receiving hole 21 meets expectations. The rotating handle 200 is connected to one end of the detection head 100 along the axial direction X. The rotating handle 200 can be used by the operator to hold and rotate the detection head 100 in the receiving hole 21. Alternatively, the rotating handle 200 can be connected to other tooling, which controls the rotation of the handle to rotate the detection head 100 in the receiving hole 21. In actual operation, the depth to which the detection head 100 extends into the receiving hole 21 may be too deep or too shallow, in which case it can be determined that the shape of the receiving hole 21 does not meet expectations. When the shape of the outer wall of the detection head 100 matches the shape of the inner wall of the receiving hole 21, the depth to which the detection head 100 extends into the receiving hole 21 is at a preset position. For example, the preset position is defined as the opening of the receiving hole 21 and the end face of the detection head 100 near the rotating handle 200 being approximately on the same horizontal plane. At this point, it can be determined that the shape of the receiving hole 21 meets expectations. After the detection head 100 extends into the receiving hole 21, the detection head 100 can be rotated in the circumferential direction Z by rotating the handle 200. Simultaneously, the matching between the receiving hole 21 and the interior of the detection head 100 can be observed through the observation area 110, further confirming whether the shape of the receiving hole 21 meets expectations. The observation area 110 may include, but is not limited to, a transparent area, an opening penetrating the side wall of the detection head 100, etc., with the circumferential direction Z of the detection head 100 surrounding the axial direction X of the detection head 100.
[0037] Through the above implementation method, the rotating handle 200 is connected to one end of the detection head 100 in the axial direction X. After the detection head 100 is inserted into the receiving hole 21 of the electrode cap 20, the rotating handle 200 can drive the detection head 100 to rotate in the receiving hole 21. The detection head 100 is provided with an observation area 110, which extends along the axial direction X to the end side of the detection head 100 connected to the rotating handle 200. During the rotation of the detection head 100, the matching state between the detection head 100 and the receiving hole 21 in the receiving hole 21 can be observed through the observation area 110. In this way, the receiving hole 21 can be tested by the detection head 100, reducing the risk of water leakage and poor soldering caused by the electrode cap 20 not meeting the requirements in subsequent use.
[0038] Combination Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the structure of the first embodiment of the electrode cap detection device provided in this application. Figure 4 This is a schematic diagram of the structure of the second embodiment of the electrode cap detection device provided in this application.
[0039] The observation area 110 penetrates the opposite surfaces of the detection head 100 along the axial direction X. For example... Figure 2 and Figure 4 As shown, the observation area 110 can extend from one end of the detection head 100 to the other end along the axial direction X, thereby enabling the observation of the matching between the receiving hole 21 and the inside of the detection head 100 from the side near the rotating handle 200.
[0040] In some embodiments, the observation area 110 penetrates the sidewall of the detection head 100 along the radial direction Y. For example... Figure 4 As shown, the observation area 110 can be a slot structure. The observation area 110 has a depth along the radial direction Y, and the depth of the observation area 110 can be set according to the actual situation. The observation area 110 can penetrate through the two sides of the detection body in the axial direction X, thereby expanding the space range exposed by the observation area 110 and enabling a more comprehensive observation of the position of the detection head 100 in the receiving hole 21.
[0041] In some embodiments, the observation area 110 is a fan-shaped region 120, and the central angle A corresponding to the observation area 110 is greater than or equal to 30° and less than or equal to 90°. For example... Figure 3 As shown, the observation area 110 has a fan-shaped cross-section on a reference plane perpendicular to the axial direction X. The rotating handle 200 is connected to the central region of the detection head 100, allowing the rotating handle 200 to avoid contact with the fan-shaped area 120. The central angle A corresponding to the fan-shaped area can be greater than or equal to 30° and less than or equal to 90°, greater than or equal to 35° and less than or equal to 90°, greater than or equal to 45° and less than or equal to 90°, greater than or equal to 30° and less than or equal to 60°, greater than or equal to 60° and less than or equal to 90°, greater than or equal to 30° and less than or equal to 45°, etc. Specifically, the central angle A corresponding to the fan-shaped area can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 70°, 80°, or 90°, etc.
[0042] Furthermore, at least a portion of the outer wall of the detection head 100 is conical, and the taper of the detection head 100 is between 1:9 and 1:20. The detection head 100 may have a partially conical outer wall, or the entire detection head 100 may be conical. The specific shape of the outer wall of the detection head 100 can be set according to the shape of the inner wall of the receiving hole 21. The taper of the detection head 100 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 head 100 can be 1:9, 1:9.6, 1:10, 1:12, 1:14, 1:16, 1:18, 1:20, etc.
[0043] In some embodiments, the dimension of the detection head 100 in the axial direction X is between 50 mm and 80 mm. The dimension of the detection head 100 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 dimension of the detection head 100 in the axial direction X can be 50 mm, 55 mm, 65 mm, 70 mm, 75 mm, or 80 mm, etc.
[0044] In some embodiments, the radial dimension of the detection head 100 near the rotating handle 200 is between 12mm and 30mm. The diameter of the opening of the detection head 100 can be between 12mm and 30mm, between 15mm and 30mm, between 18mm and 30mm, between 12mm and 25mm, between 12mm and 20mm, between 20mm and 30mm, between 20mm and 25mm, etc. Specifically, the opening of the detection head 100 can be 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 24mm, 26mm, 28mm, or 30mm, etc.
[0045] See further Figure 4The rotating handle 200 includes a first rod segment 210 and a second rod segment 220 connected to each other. The end of the first rod segment 210 away from the second rod segment 220 is connected to the detection head 100. The radial dimension of the first rod segment 210 is smaller than that of the second rod segment 220. This smaller radial dimension reduces the risk of the rotating handle 200 obstructing the observation area 110. Simultaneously, the larger radial dimension of the second rod segment 220 facilitates the operator's grip on the second rod segment 220 to rotate the detection head 100 within the receiving hole 21. The outer wall of the second rod segment 220 may also be provided with an anti-slip structure, such as including, but not limited to, a protective sleeve or anti-slip teeth on the outer wall of the second rod segment 220. The radial dimension of the second rod segment 220 in the Y direction can be between 30mm and 50mm, for example, 30mm, 35mm, 40mm, 45mm, or 50mm, etc. The dimension of the second segment 220 along the axial direction X can be between 80mm and 100mm. Specifically, the dimension of the second segment 220 along the axial direction X can be between 80mm, 85mm, 90mm, 95mm or 100mm, etc.
[0046] Furthermore, the radial dimension of the first segment 210 is configured to avoid the observation area 110 in the axial direction X. Exemplarily, the first segment 210 can be connected to a location outside the observation area 110 of the detection head 100, and the radial dimension of the first segment 210 can be between 5mm and 7mm, for example, between 5.5mm and 7mm, between 6mm and 7mm, between 6.5mm and 7mm, between 5mm and 6.5mm, between 5.5mm and 6.5mm, etc. Specifically, the radial dimension of the first segment 210 can be 5mm, 5.4mm, 5.5mm, 5.8mm, 6mm, 6.2mm, 6.4mm, 6.5mm, 6.8mm, or 7mm. The dimension of the first rod segment 210 in the axial direction X can be between 30mm and 50mm. For example, the dimension of the first rod segment 210 in the axial direction X can be 30mm, 35mm, 40mm, 45mm or 50mm, etc.
[0047] In summary, the rotating handle 200 is connected to one end of the detection head 100 in the axial direction X. After the detection head 100 is inserted into the receiving hole 21 of the electrode cap 20, the rotating handle 200 can drive the detection head 100 to rotate in the receiving hole 21. The detection head 100 is provided with an observation area 110, which extends along the axial direction X to the end side of the detection head 100 connected to the rotating handle 200. During the rotation of the detection head 100, the matching state between the detection head 100 and the receiving hole 21 can be observed through the observation area 110. In this way, the receiving hole 21 can be tested by the detection head 100, reducing the risk of water leakage and poor soldering caused by the electrode cap 20 not meeting the requirements in subsequent use.
