Description

Technical Field

[0001] The utility model relates to the field of an electrode cap display state detection device, in particular to an electrode cap display state detection device. Background Art

[0002] The electrode cap is a type of welding electrode used for resistance welding equipment, such as fixed spot welders, hanging spot welders, and manipulator spot welders. Because it is placed on the electrode connecting rod, it is called an electrode cap. After a certain number of welding, it needs to be repaired or replaced due to wear and tear, and is a welding consumable part. In the welding of automotive sheet metal, after the welding machine or welding clamp has been working for a period of time, the surface of the electrode cap at the end will be oxidized or will be sticky with impurities, affecting the quality of the weld. Therefore, the electrode cap must be replaced regularly.

[0003] Existing electrode cap replacement equipment needs to detect the displayed electrode caps to ensure that each time the electrode connecting rod replaces the electrode cap, there are always two new electrode caps that can be used for replacement. Especially when cooperating with a robot to perform the electrode cap replacement work, the detection of the display status can help the robot to efficiently complete the electrode cap replacement work. However, existing manual inspection often increases labor costs, and the accuracy of the detection device is poor. It is impossible to determine that the replaceable electrode cap is always displayed at the front end, which affects the replacement efficiency of the electrode cap. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] See also Figure 1 to Figure 2 The present utility model embodiment discloses an electrode cap display state detection device, including a cap outlet portion 1, a limit card plate 2 and a detection module 3, wherein the cap outlet portion 1 is provided with a cap outlet channel 11, and the first surface 4 and the second surface 5 of the cap outlet portion 1 are both provided with a cap outlet 12 connected to the cap outlet channel 11, the limit card plate 2 is arranged on one side of the cap outlet 12, and the detection module 3 is installed on the third surface 6 of the cap outlet portion 1 and close to the cap outlet 12.

[0022] It should be explained that the existing electrode cap detection module is often arranged on the side of the cap outlet part 1, and the forward pushing direction of the electrode cap 7 in the cap outlet channel 11 is different from the direction of the detection module, which may easily cause mismeasurement or inaccurate measurement results, that is, the electrode cap exists but the position is deviated, which leads to the inability of the cooperating robot to align the electrode connecting rod with the electrode cap at the cap outlet 12 according to the planned working trajectory, and finally leads to the failure of replacing the electrode cap, affecting the continuity of work and production efficiency, and the shutdown for maintenance will also lead to an increase in production costs.

[0023] Furthermore, the detection device arranged on the front side of the cap outlet 11 can improve the detection accuracy by adjusting the detection distance. Since the cap outlet channel 1 and the detection module are in the same vertical direction, the electrode cap 7 pushed in the cap outlet channel 11 will be detected when it accurately reaches the position of the cap outlet 12, and then the pushing of the electrode cap 7 will be stopped. Such precise positioning can reduce the ineffective work of the robot replacing the electrode cap caused by detection errors, stabilize the work flow on the production line, reduce shutdowns for maintenance, and thus improve production efficiency.

[0024] As a preferred embodiment, the cap outlet portion 1 includes at least two cap outlet channels 11 .

[0025] Specifically, the cap outlet channel 11 can be added according to demand to simultaneously replace the electrode caps of two or more electrode connecting rods, which can be adapted to most application scenarios and meet production needs.

[0026] As a preferred embodiment, the cap outlet channel 11 is bent from a position perpendicular to the center of the cap outlet portion 1 and extends to the left and right sides of the cap outlet portion 1 .

[0027] Specifically, the cap outlet channels 11 extending to the left and right sides respectively can prevent the cap outlet channels 11 from interfering with each other, and such a design also affects the position of the cap outlet port 12, thereby avoiding detection interference of the detection modules of each cap outlet port 12. At the same time, the bent cap outlet channel 11 can increase the capacity of the channel compared to the straight channel, and can be filled with multiple electrode caps 7 to ensure production continuity, reduce the number of times the electrode cap 7 is filled and the time consumed, and further increase production efficiency.

[0028] As a preferred embodiment, the cap outlet 12 is formed by the cap outlet channel 11 that is bent and extended at the upper right corner of the first surface 4 of the cap outlet portion 1 and the lower left corner of the second surface 5 of the cap outlet portion 1 .

[0029] Specifically, the cap outlet 12 is staggeredly arranged on the first surface 4 and the second surface 5 based on the mirror image of the center line of the cap outlet 1, which can avoid mutual interference between the detection modules beside the two cap outlets 12 and reduce the problem of inaccurate detection accuracy caused by interference.

[0030] As a preferred embodiment, the limit clamping plate 2 is detachably connected by installing bolts to adjust the diameter of the cap outlet 12.

[0031] Specifically, the caliber of the cap outlet 12 at the outlet of the cap outlet channel 11 can be adjusted by the limiting clamping plate 2 to adapt to different electrode cap sizes, and can be flexibly configured in the production process of electrode cap replacement to improve practicality.

[0032] As a preferred implementation, the detection module 3 is provided with at least one sensing head 31 for detecting the electrode cap 7 , and the sensing head 31 and the electrode cap 7 are located on the same horizontal plane.

[0033] Specifically, the number of the sensing heads 31 can be adjusted for detection accuracy and it can be ensured that the sensing heads 31 located on the same horizontal plane can enter the sensing range of the electrode cap displayed at the front end.

[0034] The utility model detects the electrode cap displayed at the front end of the cap outlet channel through a detection module arranged at the cap outlet, and determines whether there is always a new electrode cap that can be replaced at the front end, which is convenient for replacing the electrode cap in cooperation with a robot, can replace manual detection and improve the accuracy of electrode cap detection, and stably improve the production efficiency of electrode cap replacement.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
