[0001] The utility model relates to the technical field of welding machine detection, in particular to a welding point height detection device. Background Art

[0002] Currently, the following process is commonly used in the welding process of Bluetooth TWS / OWS speaker components:

[0003] ① The welder first places the workpiece to be welded on the welding equipment for positioning, and then uses the welding equipment to perform welding operations;

[0004] ② After welding is completed, the welder places the workpiece on a detection device (such as a height gauge, microscope, etc.) for positioning, and then inspects the height of the weld after positioning is completed.

[0005] This traditional method has the following disadvantages:

[0006] The workpiece to be welded needs to be positioned in the welding and inspection steps in sequence. It is difficult to achieve high consistency in the positioning basis of the welding equipment and the inspection mechanism. Therefore, when the weld height is detected, the detection result is less accurate.

[0007] Therefore, it is necessary to develop a weld height detection device to solve the problem that the positioning reference consistency between the welding equipment and the detection mechanism is poor, resulting in low accuracy of the weld height detection results.

[0008] The above information disclosed in this Background section is included only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is currently known to a person of ordinary skill in the art. Utility Model Content

[0009] One purpose of the present invention is to provide a welding spot height detection device that can effectively solve the problem of poor consistency in positioning references between welding equipment and detection mechanism, resulting in low accuracy of welding spot height detection results.

[0010] To achieve the above objectives, the present invention provides a device for detecting the height of a solder joint, comprising:

[0011] A detachable jig is used to clamp and fix the workpiece to be welded, and the detachable jig is provided with an avoidance notch for the welding head to enter at the welding position corresponding to the workpiece to be welded;

[0012] A detection mechanism is slidably connected to the detachable jig, and the detection mechanism is provided with a stop component at a position corresponding to the avoidance gap; wherein, when the welding point of the workpiece to be welded is too high, the stop component abuts against the welding point to limit the detachable jig from continuing to slide.

[0013] Optionally, the detachable jig comprises:

[0014] a jig base provided with a workpiece placing groove for placing the workpiece to be welded and the avoiding notch communicated to the workpiece placing groove;

[0015] a jig cover plate hinged at one end to the jig base for pressing the workpiece to be welded against the jig base.

[0016] Optionally, the other end of the jig cover plate is magnetically connected to the jig base.

[0017] Optionally, the detection mechanism further comprises:

[0018] a detection base plate provided with a guide sliding groove slidably connected to the detachable jig, and the stopper component protrudes from the top corner position of the guide sliding groove.

[0019] Optionally, a raised pad is arranged between the stopper component and the detection base plate.

[0020] Optionally, the detection base plate and the stopper component are detachably connected to the raised pad.

[0021] Optionally, the top surface of the detection base plate is provided with a plug rod blind hole, the raised pad is provided with a rod passing through hole corresponding to the position of the plug rod blind hole, and the bottom of the stopper component is provided with a vertical plug rod inserted into the plug rod blind hole through the rod passing through hole.

[0022] Optionally, the detection base plate and the stopper component are magnetically connected to the raised pad.

[0023] Optionally, the raised pad is made of iron, and the surfaces of the detection base plate and the stopper component close to the raised pad are both provided with a magnet.

[0024] The welding point height detection device has the advantages that the workpiece to be welded is first placed in the detachable jig, then the detachable jig together with the workpiece to be welded is placed on the welding equipment, the welding head of the welding equipment welds the welding position of the workpiece to be welded through the avoiding notch, and a welding point is formed.

[0025] Then, the detachable jig together with the workpiece to be welded is taken out of the welding equipment and then placed in the detection mechanism, and the detachable jig is pushed. If the welding point of the workpiece to be welded is not too high, the detachable jig can slide to the limit position. If the welding point of the workpiece to be welded is too high, the stopper component abuts against the welding point before the detachable jig slides to the limit position, so as to limit the continuous sliding of the detachable jig. Therefore, whether the welding point of the workpiece to be welded is too high or not can be judged according to the sliding stop position of the detachable jig.

[0026] Since the workpieces to be welded are located in the detachable fixture during welding and detection, the detachable fixture is used as the positioning reference of the workpieces to be welded, therefore, the welding point height detection device provided by the utility model can effectively solve the problem of poor consistency of the positioning reference of the welding equipment and the detection mechanism, which leads to low accuracy of the detection result of the welding point height.

[0041] Referring to Figure 1 and Figure 2 The utility model provides a welding spot height detection device, including detachable fixture 1 and detection mechanism 2.

[0042] The detachable fixture 1 is used for clamping and fixing the workpiece to be welded, and the detachable fixture 1 is provided with a avoiding gap 1021 for the welding head to enter at the welding position of the workpiece to be welded.

[0043] In the embodiment, the detachable fixture 1 includes a fixture base 101 and a fixture cover plate 102. The fixture base 101 is provided with a workpiece placing groove for placing the workpiece to be welded, and the avoiding gap 1021 connected to the workpiece placing groove. One end of the fixture cover plate 102 is hinged to the fixture base 101, used to press the workpiece to be welded together with the fixture base 101.

[0044] The structure design makes the workpiece to be welded always remain in the same fixture during welding and detection, ensures the accuracy of workpiece positioning, reduces the positioning error caused by workpiece movement, and improves the reliability of welding spot height detection.

[0045] The detection mechanism 2 is slidingly connected with the detachable fixture 1, and the detection mechanism 2 is provided with a stop component 202 corresponding to the position of the avoiding gap 1021; when the welding spot of the workpiece to be welded is too high, the stop component 202 abuts against the welding spot to limit the continuous sliding of the detachable fixture 1.

[0046] The welding spot height detection device provided in the embodiment is used to first place the workpiece to be welded into the detachable fixture 1, then place the detachable fixture 1 together with the workpiece to be welded on the welding equipment, and the welding head of the welding equipment welds the welding position of the workpiece to be welded through the avoiding gap 1021 to form a welding spot.

[0047] Then, the detachable jig 1 is taken out from the welding equipment together with the workpiece to be welded, and then placed in the detection mechanism 2, and the detachable jig 1 is pushed, if the welding point of the workpiece to be welded is not too high, the detachable jig 1 can slide to the limit position, if the welding point of the workpiece to be welded is too high, the stop component 202 abuts against the welding point before the detachable jig 1 slides to the limit position, so as to limit the detachable jig 1 to continue to slide. Therefore, whether the welding point of the workpiece to be welded is too high can be judged according to the sliding stop position of the detachable jig 1.

[0048] Since the workpiece to be welded is located in the detachable jig 1 during welding and detection, and the detachable jig 1 is used as a positioning reference of the workpiece to be welded, the welding point height detection device provided by the utility model can effectively solve the problem that the positioning reference consistency of the welding equipment and the detection mechanism 2 is poor, thereby reducing the accuracy of the detection result of the welding point height.

[0049] Optionally, the other end of the jig cover plate 102 is magnetically connected with the jig base 101. The magnetic connection makes the connection of the jig cover plate 102 and the base more convenient, reduces the assembly and disassembly time, improves the production efficiency, and ensures the reusability and stability of the jig.

[0050] In the embodiment, the detection mechanism 2 further comprises a detection base plate 201, the detection base plate 201 is provided with a guide sliding groove 2011 which is slidably connected with the detachable jig 1, and the stop component 202 protrudes from the top corner position of the guide sliding groove 2011.

[0051] The design of the guide sliding groove 2011 enables the detachable jig 1 to slide stably during detection, thereby improving the detection accuracy and repeatability. The stop component 202 protrudes from the top corner position of the guide sliding groove 2011, and when the welding point height is too high, the stop component 202 can effectively prevent the detachable jig 1 from sliding to the top corner position of the guide sliding groove 2011, so that whether the welding point is too high can be directly judged by observing whether the detachable jig 1 can slide to the top corner position of the guide sliding groove 2011.

[0052] Optionally, the stop component 202 and the detection base plate 201 are provided with a height increasing pad 203 therebetween, and the detection base plate 201 and the stop component 202 are detachably connected with the height increasing pad 203.

[0053] The use of the height increasing pad 203 increases the height adjustment range of the detection mechanism 2, so that the device can adapt to the welding point detection requirements of different heights, and the versatility and flexibility of the detection device are improved. The thickness of the height increasing pad 203 can be controlled, that is, the stop height of the stop component 202 can be controlled. Therefore, when different welding point height detection requirements need to be met, only the height increasing pad 203 with different thickness needs to be replaced.

[0054] In this embodiment, the top surface of the detection base plate 201 is provided with a plug rod blind hole, the heightening pad plate 203 is provided with a through rod hole corresponding to the position of the plug rod blind hole, and the bottom of the stop component 202 is provided with a vertical plug rod inserted into the plug rod blind hole through the through rod hole. Both the detection base plate 201 and the stop component 202 are magnetically connected with the heightening pad plate 203.

[0055] For example, the heightening pad plate 203 is made of iron, and both the detection base plate 201 and the stop component 202 are provided with magnets near the surface of the heightening pad plate 203.

[0056] The design of the plug rod blind hole and the through rod hole, as well as the use of the vertical plug rod, ensures the accurate positioning and horizontal limiting of the stop component 202 and the heightening pad plate 203. The magnetic connection between the detection base plate 201, the stop component 202 and the heightening pad plate 203 not only makes the height adjustment more convenient and reduces the assembly time, but also ensures the stability of the vertical connection and avoids the displacement of the components due to vibration and other reasons.

[0057] In some other embodiments, bolts can be directly used to pass through the stop component 202 and the heightening pad plate 203 and then be screwed with the detection base plate 201, thereby completing the installation and positioning of the stop component 202 and the heightening pad plate 203.

[0058] In summary, the welding point height detection device provided by the embodiment has the following advantages:

[0059] ① Improving the accuracy of welding point height detection: through the cooperation of the detachable jig 1 and the detection mechanism 2, the consistency of the positioning of the workpiece during welding and detection is ensured, thereby reducing the positioning error and improving the accuracy of welding point height detection.

[0060] ② Increasing the operation convenience: the design of the detachable jig 1 makes the clamping and removal of the workpiece more convenient, and the magnetic connection of the jig cover plate 102 and the base further simplifies the operation process and improves the work efficiency.

[0061] ③ Improving the detection efficiency: through the simple sliding and stopping mechanism, the operator can quickly judge whether the welding point is too high without the need for complex measuring tools, thereby saving detection time and reducing equipment cost.

[0062] ④ Optimizing the adaptability of the equipment: the use of the heightening pad plate 203 and the design of detachable connection make the detection device adapt to the welding point detection requirements of different heights, increasing the universality of the equipment.

[0063] ⑤Enhanced stability of the device: The design of the guide chute 2011 and the stopper component 202, as well as the magnetically connected raised pad 203, collectively ensure the stability of the device during the detection process, reducing errors caused by device vibration or component displacement.

[0064] ⑥Improved continuity of the production process: Due to the seamless integration of weld height detection and the welding process, the intermediate links are reduced, improving the continuity and overall efficiency of the production line.

[0065] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, they do not limit the scope of patent protection of the present application.
