Description

However, the height detection of the hot melting head after hot melting is an important link to ensure the quality and stability of the hot melting connection. The existing method for detecting the height of the hot melting head after hot melting is visual inspection.

[0027] In order to make the objectives, features, and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0028] The embodiments of the present disclosure will be described in detail below with reference to the drawings.

[0029] Refer to Figures 1 to 5 As shown, a detection fixture according to an exemplary embodiment of the present disclosure includes a detection mechanism 1 and a carrying mechanism 2. The detection mechanism 1 includes a fixed plate 11, a data processing module 12 disposed on the fixed plate 11, and a plurality of probe modules 13 electrically connected to the data processing module 12. The plurality of probe modules 13 penetrate through the fixed plate 11. The carrying mechanism 2 is used to carry a product to be tested 3, and a plurality of heat melt heads 31 after heat melting are provided on the product to be tested 3. The plurality of probe modules 13 are correspondingly arranged with the plurality of heat melt heads 31 after heat melting. Among them, the probe module 13 is configured to detect the height of the heat melt head 31 after heat melting.

[0030] In this embodiment, since the height detection of the product after hot melting, especially in processes such as material processing, welding, and cladding, is an important quality control link, the detection jig of the present disclosure is used to detect the height of the hot melt head 31 of the product 3 to be tested after hot melting. The probe module 13 has a contact end, and the contact end passes through the fixing plate 11 and faces the bearing mechanism 2 for detecting the product 3 to be tested. The probe module 13 converts the physical or chemical changes sensed by the contact end into electrical signals or other forms of signals, and then converts the signals into a data form readable by a computer through steps such as data acquisition, processing, and storage of the data processing module 12. The probe module 13 can specifically adopt an elastic probe module, a cantilever probe module, or a vertical probe module, and preferably an elastic probe module. The elastic probe module is designed for axial elastic force sensing, measures the force sensing of the hot melt head 31 after being heated inside, and conducts it to the data processing module 12 to convert it into a relative measurement height. Since the probe module 13 is designed to be small, it can be flexibly arranged. It can not only measure the height of the hot melt head 31 after hot melting on the same reference plane, but also be used for measurement between stepped surfaces with different height differences. The distance between the probe modules 13 and the height set relative to the fixing plate 11 can be adaptively designed according to actual needs. Therefore, since the detection jig includes the detection mechanism 1, the data processing module 12 on the fixing plate 11 of the detection mechanism 1 is electrically connected to the probe module 13. The probe module 13 has good compatibility, low cost, can be used for different height difference detections, is convenient to install, occupies a small space, can be distributed at multiple points in the vicinity, can simultaneously perform real-time height detection on all the hot melt heads of the product 3 to be tested on the bearing mechanism 2, has a fast detection speed and high efficiency; the data processing module 12 can automatically calculate and intuitively output the height information of each hot melt head, which is intuitive and efficient.

[0031] Referring to Figure 6 As shown, in an implementable embodiment, the probe module 13 includes a bracket 131, a probe 132, and a wire 133. The bracket 131 is fixedly connected to the fixing plate 11, the probe 132 passes through the bracket 131 and is fixed to the fixing plate 11 through the bracket 131, and the probe 132 is connected to the data processing module 12 through the wire 133.

[0032] Specifically, in an implementable embodiment, the bracket 131 includes a first frame body 1311 and a second frame body 1312. The first frame body 1311 and the second frame body 1312 are fixedly connected to the fixing plate 11 through fasteners 9. The probe module 13 further includes a washer 10, and the washer 10 is arranged at the fastening connection between the second frame body 1312 and the fixing plate 11.

[0033] In one embodiment, the probe 132 includes an outer tube 1321, a spring 1322 and a needle body, the needle body having a needle head 1323 and a needle tail, the needle head 1323 is used to directly contact the hot melt head 31 after hot melting, the needle tail is connected to the wire 133, the spring 1322 is located between the needle head 1323 and the needle tail to provide elastic force and restoring force, and the spring 1322 and the needle body are arranged in the outer tube 1321.

[0034] In this embodiment, the shape and material of the needle 1323 have a direct impact on the accuracy and effect of the test. The needle 1323 is usually made of a material with high hardness, high conductivity and wear resistance, such as tungsten, beryllium copper, palladium alloy, etc. The shape of the needle 1323 can be adaptively designed according to the test requirements, for example, including but not limited to a pointed head, a flat head, a V-shaped head or a spherical head, etc., to ensure good contact with the surface of the object to be tested. In the embodiments shown in the present disclosure, the needle 1323 is taken as an example of a flat head. The needle tail is usually made of stainless steel, beryllium copper or other metal alloys with good conductivity and mechanical strength, and is connected to the data processing module 12 through the wire 133 to ensure that the signal can be transmitted stably and accurately. The spring 1322 provides the necessary elastic force and restoring force to ensure that the needle 1323 can stably contact the hot melt head 31 after hot melting during the test. The outer tube 1321 is usually made of metal or plastic to protect the internal components from the external environment and provide additional mechanical support. In the actual production process, the probe module 13 can be adaptively designed according to the number, position and distribution of the hot melt heads 31 after hot melting on the product 3 to be tested, such as increasing, reducing, modifying the height and position distribution design, etc., and using the fixed plate 11 of the corresponding size specifications, and modifying the length of the wire 133 as needed to achieve the versatility of the detection fixture. In order to meet the one-time detection of all hot melt heads 31 after hot melting, each hot melt head requires a probe module 13. Compared with the solution of using infrared detection of hot melt heads, this structure is cheaper and easier to operate and detect. After hot melting, the product 3 to be tested can be directly placed on the detection fixture to confirm which hot melt heads have problems, and the problematic hot melt heads can be modified on site, which is convenient for subsequent batch measurement operations.
