Description

Technical Field

[0001] This application relates to the field of product testing technology, specifically to a testing device. Background Technology

[0002] In the manufacturing process of electronic products, the machining accuracy of specific dimensions (such as depth, height, step difference, positional accuracy, etc.) is related to the precision of the fit between the functional modules and electronic components that are fastened to them. The accuracy of these dimensional inspections directly affects the quality of electronic products. For example, in the hot forging process of mobile phone frame components, defects such as collapsed edges or missing material often form at the corners due to the influence of forging process and other factors, which in turn affects the overall assembly quality and performance of the mobile phone. In order to ensure the stability of the quality of subsequent machine tool processes, it is necessary to monitor the vertical dimension of the forged product at a designated location as a benchmark for subsequent machine tool process probes.

[0003] Currently, the industry typically uses three-dimensional contact measuring instruments or dedicated go / no-go gauge mechanisms for inspection. However, three-dimensional contact measuring instruments are limited by the operating environment and inspection frequency, and cannot meet the on-site requirements in terms of accuracy and efficiency. Dedicated go / no-go gauge mechanisms often cannot clearly perceive and judge when the product size is in a critical state, and cannot accurately detect the dimensional status, resulting in misjudgments. These problems lead to bottlenecks in the accuracy and efficiency of dimensional inspection in the electronic product manufacturing process, affecting product quality and production schedule.

Detailed Implementation

[0063] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0064] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the two; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two elements or the interaction between two elements. In the description of this application, it should be noted that "multiple" means two or more, unless otherwise expressly and specifically limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0065] The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0066] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of product 200 applicable to embodiments of this application. Specifically, product 200 is generally U-shaped, and the top inner side of product 200 is provided with an inspection surface 200a. During the production process, defects such as collapsed edges and missing materials may occur on the inspection surface 200a, causing the vertical height of the inspection surface 200a to decrease. In this embodiment, product 200 is a conductive component. Inspection surfaces 200a without collapsed edges or missing materials are considered qualified products 200, while inspection surfaces 200a with collapsed edges or missing materials are considered unqualified products 200.

[0067] To facilitate understanding and description, a three-dimensional coordinate system has been added to some of the accompanying drawings. Specifically, the X-axis is the first direction, the Y-axis is the second direction, and the Z-axis is the third direction. The X-axis, Y-axis, and Z-axis are all perpendicular to each other.

[0068] Please see Figure 2 and Figure 3This application provides a detection device 100, including a base 110, a support 120, a positioning mechanism 130, and a detection mechanism 140. The base 110 supports a product 200 and is in conductive contact with the product 200. The support 120 includes an insulating member 121 and a support member 122. The insulating member 121 is disposed on and detachably connected to the base 110, and the support member 122 is disposed on and detachably connected to the insulating member 121. A detection space 100a for accommodating the product 200 is formed between the support member 122 and the base 110. The positioning mechanism 130 positions the product 200 in the X-axis, Y-axis, and Z-axis directions. The detection mechanism 140 includes a detection element 141, an indicator element 142, and a power supply element 143. The detection element 141 is movably disposed on the support element 122 along the Z-axis and can extend to the detection space 100a. The indicator element 142 is disposed on the base 110 and is electrically connected to the detection element 141. The power supply element 143 is disposed on the base 110 and is electrically connected to the indicator element 142 and the base 110 respectively.

[0069] It should be noted that, in this embodiment, after the product 200 is placed on the base 110, the surface to be inspected 200a is positioned facing the inspection element 141, and can contact the inspection element 141 when it moves along the Z-axis direction. That is, after pressing the inspection element 141 to the set position along the Z-axis direction, if the inspection element 141 can contact the surface to be inspected 200a, then the indicator 142, the power supply 143, the base 110, the product 200, and the inspection element 141 are sequentially connected to form a closed loop, thereby triggering the indicator 142, indicating that the product 200 is qualified. Correspondingly, if the surface to be inspected 200a cannot contact the inspection element 141 when it moves along the Z-axis direction, and the indicator 142 cannot be triggered, then the product 200 is unqualified.

[0070] When the aforementioned testing device 100 tests product 200, it first places product 200 on base 110 and positions product 200 in testing space 100a. Then, the positioning mechanism 130 positions product 200 in three perpendicular directions, effectively positioning product 200. Finally, the testing element 141 is pressed along the Z-axis, causing the testing element 141 to move downwards a set distance along the Z-axis. If the indicator 142 is triggered, it indicates that product 200 is qualified; if the indicator 142 is not triggered, it indicates that product 200 is unqualified.

[0071] Therefore, the above-mentioned detection device 100 determines whether the surface 200a of the product 200 is qualified by whether the indicator 142 is triggered, which simplifies the detection process, reduces labor intensity, and helps to improve detection efficiency. In addition, the above-mentioned detection device 100 has a simple structure and low manufacturing cost, which helps to reduce detection costs.

[0072] In this embodiment, the positioning mechanism 130 includes a first positioning component 131, a second positioning component 132, and a third positioning component 133. The first positioning component 131 is disposed on the base 110 and is used to abut the product 200 along the X-axis direction. The second positioning component 132 is disposed on the base 110 and is used to abut the product 200 along the Y-axis direction. The third positioning component 133 is disposed on the support member 122 and extends to the detection space 100a and is used to press the product 200 along the Z-axis direction.

[0073] Please see Figure 2 In some embodiments, the base 110 includes a support member 111 and a plurality of support columns 112. A limiting groove 111a is formed on the side of the support member 111 away from the support column 112. An insulating member 121, a first positioning component 131, and a second positioning component 132 are all disposed on the support member 111. The plurality of support columns 112 are all connected to the support member 111 and are located on the side of the support member 111 away from the insulating member 121.

[0074] Therefore, the multiple supports 112 can form an installation space for installing the power supply component 143 and the second positioning component 132, which facilitates the installation and removal of the power supply component 143 and the second positioning component 132.

[0075] It should be noted that there may be multiple locations to be inspected on the surface to be inspected 200a. Correspondingly, there are multiple detection elements 141 and multiple sets of third positioning components 133. The multiple detection elements 141, the multiple sets of third positioning components 133, and the multiple locations to be inspected correspond one-to-one. In the following description, each location to be inspected, each detection element 141, and each third positioning component 133 will be described as a single location to be inspected.

[0076] Please see Figure 2 In some embodiments, the detection element 141 includes a test pin 1411, a limiting body 1412, and a detection spring 1413. The test pin 1411 is movably inserted into the support member 122 along the Z-axis direction. The limiting body 1412 is detachably connected to the test pin 1411 and is located on the side of the support member 122 opposite to the base 110. The detection spring 1413 is sleeved on the test pin 1411, and both ends of the detection spring 1413 abut against the support member 122 and the limiting body 1412, respectively. Exemplarily, the detection spring 1413 can be a spring.

[0077] When a force is applied downward along the Z-axis to the test pin 1411, the detection projectile 1413 is compressed, which can buffer the test pin 1411 to reduce the collision between the test pin 1411 and the surface to be inspected 200a, which helps to protect the quality of the test pin 1411 and the product 200. After the force applied to the test pin 1411 is removed, the elastic force of the detection projectile 1413 is released, which elastically pushes the limiting body 1412 to drive the test pin 1411 to move upward to achieve reset.

[0078] Please see Figure 4 In some embodiments, the end of the test pin 1411 away from the limiting body 1412 is provided with three test planes 1411a. The three test planes 1411a intersect and their intersection point forms a test tip 1411b. The test tip 1411b is used to detect the surface to be inspected 200a.

[0079] Therefore, testing the tip 1411b can improve the accuracy of the test pin 1411 in detecting the surface 200a under test.

[0080] Please see Figure 2 and Figure 5 In some embodiments, the first positioning component 131 includes a first positioning member 1311, a first fixing member 1312, a first pushing member 1313, a first rotating member 1314, and a first elastic member 1315. A first positioning member 1311 is connected to a base 110. A first fixing member 1312 is connected to the base 110 and spaced apart from the first positioning member 1311 along the X-axis direction. The first fixing member 1312 covers the limiting groove 111a. A first pushing member 1313 is movably inserted through the first fixing member 1312 along the X-axis direction and has a first stop portion 1313a. One end of the first stop portion 1313a extends to the limiting groove 111a. A first rotating member 1314 is rotatably connected to the first pushing member 1313 and is used to roll against the first fixing member 1312. A first elastic member 1315 is accommodated in the limiting groove 111a, and both ends of the first elastic member 1315 elastically abut against the sidewalls of the first stop portion 1313a and the limiting groove 111a, respectively. For example, the first elastic member 1315 can be a spring.

[0081] During the inspection process, rotating the first rotating member 1314 downwards pulls the first pushing member 1313 away from the first positioning member 1311 and compresses the first elastic member 1315. At this time, the distance between the first pushing member 1313 and the first positioning member 1311 increases, facilitating the placement of the product 200. Alternatively, rotating the first rotating member 1314 upwards releases the first positioning member 1311, allowing the first pushing member 1313 to push the product 200 against the first positioning member 1311 under the elastic force of the first elastic member 1315. This reduces the distance between the first pushing member 1313 and the first positioning member 1311, achieving positioning of the product 200 in the X-axis direction. In this embodiment, the first rotating member 1314 rotates at an angle of 90° when switching between the two states.

[0082] It should be noted that the rotation direction of the first rotating member 1314 can be interchanged. That is, when the first rotating member 1314 is rotated upward, the distance between the first pushing member 1313 and the first positioning member 1311 increases, and when the first rotating member 1314 is rotated downward, the distance between the first pushing member 1313 and the first positioning member 1311 decreases.

[0083] In this embodiment, the first stop 1313a is a pin structure, the first rotating member 1314 and the first pushing member 1313 are detachably connected by the pin, and the first fixing member 1312 and the base 110 are detachably connected by the pin.

[0084] Please see Figure 2 and Figure 6 In some embodiments, the second positioning component 132 includes a second positioning member 1321, a second fixing member 1322, a second pushing member 1323, a second rotating member 1324, and a second elastic member 1325. The second positioning member 1321 is connected to the base 110, and the second fixing member 1322 is also connected to the base 110. The second fixing member 1322, the second positioning member 1321, and the insulating member 121 are sequentially arranged along the Y-axis. The second pushing member 1323 movably passes through the second fixing member 1322 along the Y-axis and has a second stop portion 1323a. The second rotating member 1324 is rotatably connected to the second positioning member 1321 and is used to roll against the second fixing member 1322. The two ends of the second elastic member 1325 elastically abut against the second stop portion 1323a and the second fixing member 1322, respectively. For example, the second elastic member 1325 can be a spring.

[0085] When the second rotating member 1324 is rotated upwards, it pulls the second pushing member 1323 away from the second positioning member 1321 and compresses the second elastic member 1325. At this time, the distance between the second positioning member 1321 and the second pushing member 1323 increases, facilitating the placement of the product 200. Alternatively, when the second rotating member 1324 is rotated downwards, it releases the second pushing member 1323, causing it to push the product 200 against the second positioning member 1321 under the elastic force of the second elastic member 1325. The distance between the second positioning member 1321 and the second pushing member 1323 decreases, thus achieving positioning of the product 200 in the Y-axis direction. In this embodiment, the second rotating member 1324 rotates at an angle of 90° when switching between the two states.

[0086] It should be noted that the rotation direction of the second rotating member 1324 can also be interchanged. That is, when the second rotating member 1324 is rotated downward, the distance between the second positioning member 1321 and the second pushing member 1323 increases, and when the second rotating member 1324 is rotated upward, the distance between the second positioning member 1321 and the second pushing member 1323 decreases.

[0087] Please see Figure 6 and Figure 7In some embodiments, the second fixing member 1322 is disposed on the side of the base 110 away from the insulating member 121, and the second pushing member 1323 includes a push rod 1323b, a pushing body 1323c, a rotating body 1323d, and an elastic body 1323e. The push rod 1323b is movably inserted through the second fixing member 1322 along the Y-axis direction. The second stop 1323a is connected to the push rod 1323b. The pushing body 1323c includes a main body 1323f and a pushing part 1323g. The main body 1323f is movably inserted through the push rod 1323b and the base 110 along the Z-axis direction. The pushing part 1323g is connected to the side of the main body 1323f facing the insulating member 121 and is used to push the product 200 to the insulating member 121. The rotating body 1323d is rotatably connected to the main body 1323f and is used to roll and hold the push rod 1323b. The elastic body 1323e is sleeved on the main body 1323f, and the two ends of the elastic body 1323e elastically hold the push rod 1323b and the pushing part 1323g, respectively. For example, the elastic body 1323e can be a spring.

[0088] When the rotating body 1323d rotates, it pulls the pushing body 1323c and compresses the elastic body 1323e, or releases the pushing body 1323c so that it returns to its original position under the elastic force of the elastic body 1323e. The rotation direction of the rotating body 1323d can be appropriately set based on its structure to achieve these two different functions.

[0089] Please see Figure 6 and Figure 7In some embodiments, the support member 122 includes a support body 1221 and an extension body 1222. The support body 1221 is disposed on the insulating member 121, and the extension body 1222 connects to the support body 1221 and encloses the support body 1221 and the base 110 to form a detection space 100a. The third positioning component 133 includes a toggle member 1331, a pressing member 1332, and a third elastic member 1333. The toggle member 1331 is inserted into the support body 1221 and can be rotated relative to the support body 1221. The surface of the toggle member 1331 is provided with a first toggle surface 1331a and a second toggle surface 1331b arranged opposite to each other. The pressing member 1332 includes a linkage body 1332a, a vertical body 1332b, a horizontal body 1332c, and a pressing member 1332d. The linkage body 1332a is movably embedded in the extension body 1222 along the Z-axis direction, and the linkage body 1332a is movably embedded in the extension body 1222. 2a connects to the vertical body 1332b and abuts against the actuating member 1331. The vertical body 1332b is movably disposed on the extension body 1222 along the Z-axis and extends to the detection space 100a. The horizontal body 1332c is vertically connected to the vertical body 1332b and is located in the detection space 100a. The pressing body 1332d is an insulating member and is connected to the horizontal body 1332c, used to press the product 200 along the Z-axis. The third elastic member 1333 is sleeved on the vertical body 1332b, and the two ends of the third elastic member 1333 abut against the horizontal body 1332c and the extension body 1222, respectively. For example, the third elastic member 1333 can be a spring.

[0090] When the actuating element 1331 rotates, the linkage 1332a rolls against the actuating element 1331. When the linkage 1332a abuts against the first actuating surface 1331a, the horizontal body 1332c moves away from the base 110 and compresses the third elastic element 1333. When the linkage 1332a abuts against the second actuating surface 1331b, the elastic force of the third elastic element 1333 is released, and the horizontal body 1332c moves closer to the base 110. The rotation direction of the actuating element 1331 can be determined based on its structural configuration to achieve these two different functions.

[0091] In this embodiment, the actuating member 1331 includes a lever 1331c rotatably disposed in the extension body 1222 and a lever block 1331d detachably connected to one end of the lever 1331c. The lever 1331c extends along the X-axis direction, and a first actuating surface 1331a and a second actuating surface 1331b are both disposed on the lever 1331c. The lever block 1331d is detachably connected to the lever 1331c by a pin.

[0092] In this embodiment, the surface of the lever 1331c is provided with a plurality of toggle grooves 1331e, and the bottom wall of each toggle groove 1331e forms a second toggle surface 1331b.

[0093] Please see Figure 6In some embodiments, the extension 1222 has a limiting groove 1222a on the side facing the base 110. The limiting groove 1222a connects to the detection space 100a and allows the vertical body 1332b to pass through. A portion of the third elastic member 1333 is accommodated in the limiting groove 1222a.

[0094] Therefore, the limiting groove 1222a can limit the third elastic element 1333 in the X-axis and Y-axis directions, which is beneficial to improving the stability of the elastic force of the third elastic element 1333 in the Z-axis direction.

[0095] Please see Figure 8 In some embodiments, the power supply component 143 includes a housing 1431, a sleeve 1432, a battery 1433, a reset component 1434, and a rotating handle 1435. The housing 1431 is connected to and electrically contacts the base 110. The sleeve 1432 is housed in the housing 1431 and embedded in the base 110, and the sleeve 1432 is an insulating component. The battery 1433 is housed in the sleeve 1432. The reset component 1434 is housed in the sleeve 1432, and the reset component 1434 is electrically connected to the indicator 142 and the battery 1433, respectively. The rotating handle 1435 is rotatably connected to the housing 1431 and rolls against the battery 1433, and the rotating handle 1435 is an insulating component.

[0096] In use, rotating the handle 1435 downwards causes it to extend into the sleeve 1432, pushing against the battery 1433 and compressing the reset member 1434, thus detaching the battery 1433 from the housing 1431. At this time, the power supply unit 143 is in a de-energized state. Alternatively, rotating the handle 1435 upwards causes it to retract from the sleeve 1432, allowing the reset member 1434 to elastically push the battery 1433 against the housing 1431. At this time, the power supply unit 143 is in a energized state. In this embodiment, the rotation angle of the handle 1435 when switching between the two states is 90°.

[0097] The working process of the above-mentioned detection device 100 is roughly as follows:

[0098] First, rotate the first rotating member 1314, the second rotating member 1324 and the actuating member 1331 to increase the distance between the first pushing member 1313 and the first positioning member 1311, and increase the distance between the second pushing member 1323 and the second positioning member 1321, so that the pressing member 1332 moves away from the bearing member 111.

[0099] Next, the product 200 is placed on the carrier 111, so that the product 200 is located in the detection space 100a, and the product 200 is located in the area enclosed by the first positioning member 1311, the first pushing member 1313, the second pushing member 1323 and the second positioning member 1321;

[0100] Then, the first rotating member 1314, the second rotating member 1324 and the actuating member 1331 are rotated so that the first pushing member 1313 pushes the product 200 to the first positioning member 1311 along the X-axis direction, the second pushing member 1323 pushes the product 200 to the second positioning member 1321 along the Y-axis direction, and the holding member 1332 holds the product 200 along the Z-axis direction, thereby achieving the positioning of the product 200;

[0101] Finally, rotate the handle 1435 to energize the power supply unit 143, press the limit body 1412 along the Z-axis to the preset distance. If the indicator 142 is triggered, the product 200 is qualified; if the indicator 142 is not triggered, the product 200 is unqualified.
