Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a detection fixture. Background Technology

[0002] Whether the pin length of electronic components on a circuit board exceeds the set maximum size is usually checked using a testing fixture. The operator pushes the testing component forward. If the pin length exceeds the set maximum size, the testing component will contact the pin, and the pin will block the testing component from moving forward. The operator judges whether the pin meets the judgment standard by the resistance felt by hand, and decides whether to push the blocking testing component to continue moving forward. However, when pushing the testing component manually, it is easy to push too hard, causing the pin that exceeds the judgment standard to be pushed over, while the testing component can pass smoothly. The operator may mistakenly judge the test component as good, thus affecting the test results. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a testing fixture with better testing effect.

[0004] A testing fixture according to an embodiment of the present invention includes a mounting base, a testing component, and a push block. The mounting base is provided with a positioning structure for positioning the test piece. The testing component is slidably mounted on the mounting base along a preset direction and is provided with a first connecting structure. The push block is provided with a second connecting structure, which is detachably connected to the first connecting structure. The first connecting structure can be disconnected from the second connecting structure when the force exerted between the push block and the testing component in the preset direction is greater than a preset value. The push block can drive the testing component to move toward the positioning structure along the preset direction.

[0005] A detection fixture according to an embodiment of the present utility model has at least the following technical effects:

[0006] In the use of the testing fixture of this application, the workpiece to be tested is first placed on the positioning structure of the mounting base. Then, the push block is driven to move. The second connecting structure of the push block drives the first connecting structure to move, thereby causing the testing component to slide along a preset direction. When the testing component slides onto the workpiece to be tested, if the actual height of the workpiece to be tested exceeds the preset height, the testing component comes into contact with the workpiece to be tested. The workpiece to be tested exerts resistance on the testing component, causing the force between the testing component and the push block in the preset direction to exceed the preset value, thereby causing the second connecting structure of the push block and the first connecting structure of the testing component to separate. From the above usage process, it can be seen that when the actual height of the workpiece to be tested exceeds the preset height, the push block will disengage from the testing component to prevent the testing component from continuing to slide along the preset direction and smoothly pass the workpiece to be tested, thereby improving the testing effect of the testing fixture.

[0007] According to some embodiments of the present invention, a detection fixture has a first connecting structure consisting of a first magnetic suction member mounted on a detection assembly, and a second connecting structure consisting of a second magnetic suction member mounted on a push block, wherein the second magnetic suction member is magnetically connected to the first magnetic suction member.

[0009] According to some embodiments of the present invention, a testing fixture includes a testing component that includes a limiting member for pressing a workpiece to be tested. A positioning structure is disposed on one side of the testing component in a preset direction. A positioning groove for positioning the workpiece to be tested is formed in the positioning structure. The positioning groove has an opening facing the testing component, and the opening allows the limiting member to pass through.

[0010] According to some embodiments of the present invention, a testing fixture has a positioning structure including a first positioning member and a second positioning member. Both the first positioning member and the second positioning member are detachably mounted on a mounting base. The first positioning member and the second positioning member are arranged side by side and both extend along a preset direction. A positioning groove is formed between the first positioning member and the second positioning member.

[0012] According to some embodiments of the present invention, a testing fixture includes a testing component that further includes multiple threaded connectors. The limiting component is provided with multiple spaced elongated holes that extend vertically. Each threaded connector can be slidably inserted into one elongated hole, and the threaded connector is threadedly connected to the gantry frame.

[0013] According to some embodiments of the present invention, a testing fixture is provided with a reference block detachably mounted on the mounting base. The reference block is located on the moving path of the testing component and can abut against the lower end face of the limiting member to calibrate the position of the limiting member in the height direction.

[0014] According to some embodiments of the present invention, a testing fixture is provided on a mounting base with two fixed rods extending in a preset direction, a positioning structure is provided between the two fixed rods, and a slider is slidably sleeved on the fixed rods.

[0026] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0027] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0028] The following is for reference. Figure 1 and Figure 2 A testing fixture according to an embodiment of the present utility model will be described in detail.

[0029] refer to Figure 1 and Figure 2 According to an embodiment of the present invention, a testing fixture includes a mounting base 100, a testing component 200, and a pusher block 300. The mounting base 100 is provided with a positioning structure 110 for positioning the test piece. The testing component 200 is slidably disposed on the mounting base 100 along a preset direction and is provided with a first connecting structure 201. The pusher block 300 is provided with a second connecting structure 310, which is detachably connected to the first connecting structure 201. The first connecting structure 201 can disconnect from the second connecting structure 310 when the force between the pusher block 300 and the testing component 200 in the preset direction is greater than a preset value. The pusher block 300 can drive the testing component 200 to move a preset distance toward the positioning structure 110 along the preset direction.

[0030] In the use of the testing fixture of this application, the workpiece to be tested is first placed on the positioning structure 110 of the mounting base 100. Then, the push block 300 is driven to move. The second connecting structure 310 of the push block 300 drives the first connecting structure 201 to move, thereby causing the testing component 200 to slide along a preset direction. When the testing component 200 slides onto the workpiece to be tested, if the actual height of the workpiece to be tested exceeds the preset height, the testing component 200 comes into contact with the workpiece to be tested. The workpiece to be tested exerts resistance on the testing component 200, causing the force between the testing component 200 and the push block 300 in the preset direction to be greater than the preset value. This causes the second connecting structure 310 of the push block 300 and the first connecting structure 201 of the testing component 200 to separate. From the above usage process, it can be seen that when the actual height of the workpiece to be tested exceeds the preset height, the push block 300 will disengage from the testing component 200 to prevent the testing component 200 from continuing to slide along the preset direction and smoothly pass the workpiece to be tested, thereby improving the testing effect of the testing fixture.

[0031] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the first connecting structure 201 is a first magnetic suction member mounted on the detection component 200, and the second connecting structure 310 is a second magnetic suction member mounted on the push block 300. The second magnetic suction member is magnetically connected to the first magnetic suction member. It can be understood that when the push block 300 is driven to move, since the second magnetic suction member of the push block 300 is magnetically connected to the first magnetic suction member of the detection component 200, the push block 300 can drive the detection component 200 to slide. When the force between the detection component 200 and the push block 300 in a preset direction is greater than a preset value, the second magnetic suction member of the push block 300 separates from the first magnetic suction member of the detection component 200.

[0032] In some other embodiments of this utility model, one of the first connecting structure 201 and the second connecting structure 310 is a suction cup, in which case the first connecting structure 201 and the second connecting structure 310 are connected by vacuum adsorption.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, the detection component 200 has a first mounting surface 202 parallel to a preset direction, and a first magnetic suction member is embedded in the first mounting surface 202. The push block 300 has a second mounting surface parallel to the preset direction, and a second magnetic suction member is embedded in the second mounting surface. It can be understood that by embedding the first magnetic suction member on the first mounting surface 202 parallel to the preset direction and the second magnetic suction member on the second mounting surface parallel to the preset direction, when the force between the detection component 200 and the push block 300 in the preset direction is greater than a preset value, the push block 300 and the detection component 200 can separate more smoothly from each other.

[0034] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the detection component 200 includes a limiting member 210 for pressing the test piece, and a positioning structure 110 is disposed on one side of the detection component 200 in a preset direction. The positioning structure 110 has a positioning groove 110a for positioning the test piece, and the positioning groove 110a has an opening facing the detection component 200, allowing the limiting member 210 to pass through. It is understood that the testing personnel place the test piece in the positioning groove 110a and use the pusher 300 to move the limiting member 210 along the preset direction, so that the limiting member 210 can slide along the preset direction on the upper side of the positioning groove 110a. When the height of the test piece exceeds the preset height, the limiting member 210 will abut against the portion of the test piece protruding beyond the preset height.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the positioning structure 110 includes a first positioning member 111 and a second positioning member 112. Both the first positioning member 111 and the second positioning member 112 are detachably mounted on the mounting base 100. The first positioning member 111 and the second positioning member 112 are arranged side-by-side and both extend along a preset direction, forming a positioning groove 110a between them. It is understood that by installing the first positioning member 111 and the second positioning member 112 on the mounting base 100 to form the positioning groove 110a, the mounting base 100 does not need to be processed, making the setting of the positioning groove 110a simpler and more convenient.

[0036] In a further embodiment of this utility model, the first positioning member 111 and the second positioning member 112 are detachably mounted on the mounting base 100. It can be understood that by disassembling and replacing the first positioning member 111 and the second positioning member 112 of different specifications, positioning grooves 110a of different sizes can be formed, thereby adapting to test pieces of different specifications.

[0037] like Figure 1 and Figure 2 As shown, in some embodiments, the detection assembly 200 further includes a gantry 220, with a limiting member 210 vertically positionably mounted on the gantry 220. The gantry 220 is slidably mounted on the mounting base 100 in a preset direction, and a first connecting structure 201 is mounted on the gantry 220. It can be understood that by adjusting the vertical position of the limiting member 210 on the gantry 220, the height of the limiting member 210 can be adjusted, thereby adjusting the detection height of the detection assembly 200, making it suitable for test pieces with different detection heights.

[0038] like Figure 1 and Figure 2As shown, in one embodiment, the detection component 200 further includes multiple threaded connectors. The limiting member 210 is provided with multiple spaced elongated holes 211 extending vertically. Each threaded connector can slidably pass through one elongated hole 211, and the threaded connector is threadedly connected to the gantry 220. It is understood that by forward-tightening the threaded connector, the limiting member 210 can slide vertically, allowing the threaded connector to slide within the elongated hole 211. When the limiting member 210 moves to a preset height, by reverse-tightening the threaded connector, the limiting member 210 can be fixed to the gantry 220.

[0039] like Figure 1 and Figure 2 As shown, in one embodiment, a reference block 120 is detachably provided on the mounting base 100. The reference block 120 is located on the moving path of the detection component 200. The reference block 120 can abut against the lower end face of the limiting member 210 to calibrate the position of the limiting member 210 in the height direction. It can be understood that by providing the reference block 120 on the mounting base 100, the limiting member 210 on the detection component 200 can be directly calibrated through the reference block 120 on the mounting base 100, thereby making it more convenient for the inspection personnel to operate; different reference blocks 120 can be replaced on the mounting base 100 to calibrate different detection heights of the limiting member 210.

[0040] refer to Figure 1 and Figure 2 In some embodiments of this utility model, the mounting base 100 is provided with two fixed rods 130 extending along a preset direction, the positioning structure 110 is disposed between the two fixed rods 130, and a slider 140 is slidably sleeved on the fixed rods 130. The detection component 200 is connected to the two sliders 140. It can be understood that by sleeved sliders 140 on the fixed rods 130 extending in the preset direction and connecting sliders 140 to the detection component 200, the detection component 200 can move accurately along the preset direction, and the guide structure of sliders 140 and fixed rods 130 is relatively simple and has a low manufacturing cost.

[0041] refer to Figure 3 A detection method, using a detection fixture as described in the above embodiments, specifically includes the following steps:

[0042] S100, Place the test piece in the positioning structure 110 of the mounting base 100;

[0043] S200, push the pusher block 300 to move a preset distance in a preset direction, so that the pusher block 300 drives the detection component 200 to approach the test piece in the positioning structure 110 in a preset direction;

[0044] S300: Determine whether the second connection structure 310 on the push block 300 and the first connection structure 201 on the detection component 200 are disconnected.

[0045] S400. If the second connecting structure 310 on the push block 300 and the first connecting structure 201 on the detection component 200 are disconnected, the test piece is determined to be defective.

[0046] S500. If the connection between the second connecting structure 310 on the push block 300 and the first connecting structure 201 on the detection component 200 is not broken, the test piece is determined to be a good product.

[0047] Understandably, the inspector first places the part to be tested in the positioning structure 110 of the mounting base 100, and then pushes the pusher 300 a preset distance in a preset direction. This causes the pusher 300 to move the detection component 200 in the preset direction and bring it close to the part to be tested within the positioning structure 110. The inspector then determines whether the second connecting structure 310 on the pusher 300 and the first connecting structure 201 on the detection component 200 are disconnected. If the second connecting structure 310 on the pusher 300 and the first connecting structure 201 on the detection component 200 are disconnected, the actual height of the part to be tested exceeds the preset height, and the part to be tested is judged to be defective. If the connection between the second connecting structure 310 on the pusher 300 and the first connecting structure 201 on the detection component 200 is not disconnected, the actual height of the part to be tested does not exceed the preset height, and the part to be tested is judged to be good. By using the above inspection method to inspect the part to be tested, the possibility of the operator misjudging the product as good due to the force applied to the pushing of the detection component can be effectively reduced.

[0048] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
