Description

Technical Field

[0001] This application relates to the field of automobile manufacturing, and in particular to a data acquisition device for penetrating force testing. Background Technology

[0002] Electrophoretic coating technology produces coatings that are dense, uniform, and have excellent adhesion, making it widely used in automotive industrial production. Penetration, a key performance indicator of electrophoretic paint, directly affects whether a uniform coating can be formed in complex areas such as weld seams, deep cavities, and inner surfaces of the substrate. Monitoring penetration allows for the timely detection and handling of potential problems during the electrophoresis process, effectively ensuring quality. Electrophoretic penetration testing methods can generally be categorized into two main types: laboratory penetration testing and production line penetration testing. Laboratory penetration testing commonly uses the four-piece box method or the Ford box method. While laboratory penetration testing has a relatively standardized and regulated testing methodology, it only reflects the inherent state of the electrophoretic paint's penetration performance and cannot accurately reflect the actual effectiveness of penetration on a production line under specific paint conditions and equipment processes. Therefore, production line penetration force testing has a greater advantage in accurately mapping the penetration force of the production line; however, production line penetration force testing still faces problems such as high cost of testing equipment, long installation time, and the significant impact of vehicle body structure and / or installation location on the penetration force test results. How to solve these problems is a question that those skilled in the art need to consider. Utility Model Content

[0057] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments. It should be noted that components depicted in the drawings are not necessarily shown to scale; and identical or similar components will be designated with the same or similar reference numerals or similar technical terms.

[0058] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0059] like Figure 1 As shown, this application embodiment provides a data acquisition device 100 for electrophoretic coating to detect the penetration force during the electrophoretic coating process. The data acquisition device 100 includes a penetration force detection box 11 and a connecting fixture 10. The connecting fixture 10 includes a detection box mounting part 12 and a connecting assembly 13; the connecting assembly 13 is used to connect with the part 2 to be processed (e.g., ...). Figure 5 As shown, (especially for automotive parts to be processed), the detection box mounting part 12 is connected to the connecting assembly 13 to fix it to the part to be processed 2, and the penetrating force detection box 11 is detachably connected to the detection box mounting part 12.

[0060] In one embodiment, the permeability testing box 11 includes a test surface 110 capable of reflecting the permeability testing result; the testing box mounting part 12 is detachably connected to the permeability testing box 11, the testing box mounting part 12 includes a slot 120 capable of accommodating the permeability testing box 11 and exposing at least a portion of the test surface 110; the connecting assembly 13 is connected to the testing box mounting part 12, the connecting assembly 13 being used to connect the permeability testing data acquisition device 100 to the part 2 to be processed by at least a snap-fit ​​and / or magnetic connection.

[0061] Furthermore, the connecting component 13 can connect the penetration force test data acquisition device 100 to the part 2 to be processed via snap-fit ​​and / or magnetic connection. The installation process is simple and quick, and has good universal adaptability, making it suitable for different parts of different vehicle models. The penetration force test box 11 is detachably connected to the test box mounting part 12 via the slot 120, making the installation process simple and quick. At the same time, the slot 120 can accommodate the penetration force test box 11 and expose at least part of the test surface 110, allowing the test surface 110 to fully participate in the penetration coating process, resulting in better detection effect. The penetration force test data acquisition device 100 provided in this application embodiment includes a separate, detachable penetration force test box 11 and a connecting fixture 10 (test box mounting part 12 and connecting component 13), which facilitates the replacement of the penetration force test box 11 and eliminates the need for frequent disassembly of the connecting fixture 10, making the installation process simple and quick. At the same time, the penetration force test data acquisition device 100 provided in this application embodiment has a simple structure and lower cost.

[0062] It is understood that the electrophoretic coating data acquisition device 100 provided in this application embodiment can simultaneously perform electrophoretic coating to detect electrophoretic coating force, realize electrophoretic coating force testing on the production line, and thus accurately guide the production line to make timely adjustments to the characteristics or process parameters of the electrophoretic paint when necessary, thereby effectively ensuring the uniformity and long-term stability of the electrophoretic film thickness in the inner cavity of the car body, and effectively improving the quality control level and production efficiency of the electrophoretic coating process.

[0063] For ease of understanding, this application introduces a first direction Z, a second direction Y, and a third direction X; wherein, the first direction Z, the second direction Y, and the third direction X can be three non-parallel straight line directions in space; further, the first direction Z, the second direction Y, and the third direction X can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the description will take the first direction Z as the axis direction of the three-dimensional coordinate system, the second direction Y as the axis direction of the three-dimensional coordinate system, and the third direction X as the axis direction of the three-dimensional coordinate system as examples.

[0064] Further integration Figure 2 and Figure 3As shown, in one embodiment, the connecting component 13 includes a first connecting structure 131 and a second connecting structure 132. The first connecting structure 131 and the second connecting structure 132 are respectively connected to the detection box mounting part 12. The first connecting structure 131 and the second connecting structure 132 are configured to connect the workpiece 2 to be processed through different connection methods. Specifically, the first connecting structure 131 can connect the penetrating force test data acquisition device 100 to the workpiece 2 to be processed by a snap-fit ​​method, and the second connecting structure 132 can connect the penetrating force test data acquisition device 100 to the workpiece 2 to be processed by a magnetic connection method.

[0065] In one embodiment, the first connection structure 131 includes a first positioning member 1311 and a first connecting member 1312. The first positioning member 1311 is connected to the detection box mounting portion 12, and the first connecting member 1312 is connected to the first positioning member 1311 and is spaced apart from the detection box mounting portion 12 along at least one direction. The first connecting member 1312 is used to connect to the part 2 to be processed.

[0066] Understandably, the first positioning member 1311 is fixed by connecting to the detection box mounting part 12. The first connecting member 1312, which is used to connect to the part to be processed 2, is spaced apart from the detection box mounting part 12 in at least one direction (e.g., the second direction Y) to avoid interference between the detection box mounting part 12 and the part to be processed 2, and to facilitate installation.

[0067] In this embodiment, the first connecting structure 131 is a split design, which is shown as an example. In other embodiments, the first positioning member 1311 and the first connecting member 1312 can also be an integral structure.

[0068] In one embodiment, the length of the first positioning member 1311 along the first direction Z is greater than the length of the detection box mounting portion 12 along the first direction Z, and the first positioning member 1311 is connected to the side of the detection box mounting portion 12 away from the slot 120 along the second direction Y. The first connecting member 1312 is provided at the end of the first positioning member 1311 that extends beyond the detection box mounting portion 12 along the first direction Z, and at least a portion of the first connecting member 1312 extends along the second direction Y toward the side away from the detection box mounting portion 12, where the first direction Z intersects the second direction Y.

[0069] In this embodiment, the first connecting member 1312 includes a first connecting rod 13121 and two second connecting rods 13122. The first connecting rod 13121 extends approximately along the third direction X and is connected to the first positioning member 1311. The two second connecting rods 13122 are respectively connected to the two ends of the first connecting rod 13121 along the third direction X. Both second connecting rods 13122 extend along the second direction Y toward the side away from the detection box mounting portion 12 and are used to engage with the part 2 to be processed.

[0070] In one embodiment, the first connecting structure 131 has a bayonet 1310, which is located on the first connector 1312. The slot of the bayonet 1310 faces the side where the detection box mounting part 12 is located, and the bayonet 1310 is used to engage with the part 2 to be processed so that the penetrating force test data acquisition device 100 is hung on the part 2 to be processed.

[0071] In this embodiment, the bayonet 1310 is located at the end of the first connector 1312 away from the detection box mounting portion 12 along the second direction Y, and the slotting direction of the bayonet 1310 is towards the side where the detection box mounting portion 12 is located along the first direction Z.

[0072] Understandably, the bayonet 1310 can engage with the part 2 to be processed (e.g., the car body or door), and under the weight of the penetrating force test data acquisition device 100, the bayonet 1310 and the part 2 to be processed can be tightly connected. The connecting fixture 10 can be hung on the part 2 to be processed through the first connecting structure 131. This connection method facilitates installation and disassembly, allows for quick removal when results need to be viewed, and enables rapid installation of the monitoring device without interrupting the production line.

[0073] In one embodiment, the first connecting structure 131 further includes a positioning pin 1313, which is connected to the first positioning member 1311. The positioning pin 1313 and the first connecting member 1312 are located on the same side of the detection box mounting portion 12 and extend in the same direction.

[0074] In one embodiment, the first positioning member 1311 has a plurality of first mounting positions 13111, the first mounting positions 13111 being used for the positioning pins 1313 to be connected thereto, and the number of first mounting positions 13111 is greater than or equal to the number of positioning pins 1313.

[0075] In this embodiment, the first positioning member 1311 includes two straight rods, each of which has a first mounting position 13111; the positioning pin 1313 is rod-shaped, and there is one positioning pin 1313. One positioning pin 1313 is connected to one of the two first mounting positions 13111. The positioning pin 1313 can be used to cooperate with the structure on the part to be processed 2 to achieve positioning; the other reserved first mounting position 13111 can also be used to connect to the other positioning pin 1313.

[0076] Understandably, the positioning pins 1313 can prevent the connecting fixture 10 from falling off during the electrophoresis process; the number and shape of the positioning pins 1313 can be adjusted according to the specific structure of the parts 2 to be processed, so that the electrophoresis penetration test data acquisition device 100 of this application has better adaptability.

[0077] In one embodiment, the second connecting structure 132 includes a magnetic element 1320, a second positioning element 1321, and a second connecting element 1322. The second positioning element 1321 is connected to the detection box mounting portion 12, and the second connecting element 1322 is detachably connected to the second positioning element 1321. The magnetic element 1320 is connected to the end of the second positioning element 1321 away from the detection box mounting portion 12. The magnetic element 1320 is used for magnetically connecting with the part 2 to be processed.

[0078] In one embodiment, the second positioning member 1321 is connected to the side of the detection box mounting portion 12 opposite to the slot 120 along the second direction Y. The second positioning member 1321 has a movable slot 13212 extending along the first direction Z, which intersects with the second direction Y. One end of the second connecting member 1322 is engaged in the movable slot 13212 and is configured to be adjustable along the first direction Z. The other end of the second connecting member 1322 extends along the second direction Y toward the side opposite to the detection box mounting portion 12 and is connected to the magnetic member 1320.

[0079] In this embodiment, the second positioning member 1321 is generally an L-shaped sheet metal part. One side wall 13211 of the second positioning member 1321 is connected to the detection box mounting part 12, and the other side wall 13211 is flipped up relative to the detection box mounting part 12 along the second direction Y. The flipped side wall 13211 is provided with a movable groove 13212. The second connecting member 1322 is connected to the side wall 13211 by a detachable or adjustable bolt. By removing or loosening the bolt, the second connecting member 1322 can move relative to the first connecting member 1312, so as to adjust the position of the second connecting member 1322 and the magnetic member 1320 connected thereto, so that the penetrating force test data acquisition device 100 of this application has better adaptability.

[0080] It is understood that the magnetic component 1320 provided in this application embodiment can be a permanent magnet or an electromagnet. The magnetic component 1320 can adjust the distance between the connecting fixture 10 and the part 2 to be processed, ensuring that the connecting fixture 10 is approximately perpendicular to the part 2 to be processed. The magnetic component 1320 also has a pre-tightening effect. The magnetic component 1320 is located at the end of the second connecting component 1322 and can be sleeved on the end of the second connecting component 1322. The magnetic component 1320 can easily attract the part 2 to be processed using magnetic force, making installation convenient and providing good installation strength. Furthermore, since the part 2 to be processed (especially the car body and doors) is usually a metal part, using the magnetic component 1320 to magnetically attract the part 2 only requires that the part 2 to be processed has a metallic material. Connection can be achieved regardless of the specific structure of the part 2, giving the penetrating force test data acquisition device 100 of this application better adaptability.

[0081] In this embodiment, there are two second connecting structures 132, which are disposed on both sides of the first connecting structure 131 along a third direction X. The two second connecting structures 132 have the same structure to ensure stable connection. In other embodiments, there may be one or more second connecting structures 132, and the length of the second connector 1322 along the second direction Y is adjustable to adapt to different types of parts 2 to be processed, so that the penetrating force test data acquisition device 100 of this application has better adaptability.

[0082] In one embodiment, the detection box mounting portion 12 includes a first mounting member 121 and a second mounting member 122 spaced apart along a first direction Z. Both the first mounting member 121 and the second mounting member 122 are provided with slots 120, and the slots 120 are positioned opposite each other along the first direction Z. The first mounting member 121 and the second mounting member 122 are arranged parallel to each other along a third direction X, and the slots 120 extend along the third direction X.

[0083] In this embodiment, the first mounting member 121 and the second mounting member 122 are arranged opposite to each other to form a receiving structure that can accommodate the swimming penetration test box 11. The swimming penetration test box 11 is held in place, and the test surface 110 is fully exposed while the swimming penetration test box 11 is firmly set.

[0084] In one embodiment, the detection box mounting part 12 includes locking members 123. Multiple locking members 123 are spaced apart along a third direction X on the first mounting member 121 and the second mounting member 122. The locking members 123 can be structures such as bolts that allow for rotational adjustment of tightness. When the permeability detection box 11 is inserted into the slot 120, the permeability detection box 11 can be locked by tightening the locking members 123; subsequently, the permeability detection box 11 can be removed from the slot 120 by loosening the locking members 123.

[0085] Further integration Figure 4 As shown, in one embodiment, the penetrating power testing box 11 includes a body 111 and a cover 112. The cover 112 is disposed on both sides opposite to the body 111 and on the test surface 110.

[0086] In this embodiment, the body 111 can be made of steel plate that has been phosphated (or zirconated / silane treated), and the cover 112 can be made of tape. The two covers 112 extend along the third direction X and are respectively attached to the two ends of the body 111 at a distance from each other along the first direction Z. When the permeability detection box 11 is placed in the slot 120, the covers 112 are approximately located in the slot 120.

[0087] In this embodiment, the cover 112 has a trapezoidal opening 113, which is used to expose the test surface 110. The trapezoidal opening 113 is provided in relation to the locking member 123.

[0088] Further integration Figure 5 As shown, the swimming penetration test data acquisition device 100 is typically installed at the door of the body-in-white.
