Description

Technical Field

[0001] This utility model relates to the field of tolerance inspection technology, and in particular to an inspection device. Background Technology

[0002] After production is completed, operators need to perform precision inspection on the workpieces to determine whether the tolerances are within the preset tolerance range. Currently, dial indicators are often used for precision inspection. However, when using a dial indicator, the measuring probe needs to be constantly adjusted using a screw mechanism to ensure accurate workpiece measurement. This constant adjustment of the measuring probe is labor-intensive and inefficient for the operator. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a detection device to reduce labor intensity and improve detection efficiency.

[0004] This application provides a detection device, including:

[0005] A support assembly includes a support member, a power supply member, and an electrical contact. The support member is used to support a workpiece. The power supply member is connected to the support member. The electrical contact is embedded in the upper surface of the support member and electrically connected to the negative terminal of the power supply member. The electrical contact is used to abut against the workpiece to be inspected.

[0006] A first detection component includes a support member, a first conductive member, a first light-emitting member, and a first detection member. The support member is movably disposed above the carrier member and is used to press the workpiece against the carrier member. The first conductive member is connected to the support member and is used to be electrically connected to the positive terminal of the power supply member. The first light-emitting member is disposed on the support member and is electrically connected to the first conductive member. The first detection member is disposed on the side of the support member facing the carrier member and is electrically connected to the first light-emitting member. The first detection member is used to abut against the workpiece that has reached the upper tolerance limit and form a conductive circuit, so that the first light-emitting member emits light.

[0007] The second detection component includes a pressing member, a second conductive member, a second light-emitting member, and a second detection member. The pressing member is movably disposed above the support member and is used to press the workpiece against the support member. The second conductive member is connected to the pressing member and is used to be electrically connected to the positive electrode of the power supply member. The second light-emitting member is disposed on the pressing member and is electrically connected to the second conductive member. The second detection member is disposed on the side of the pressing member facing the support member and is electrically connected to the second light-emitting member. The second detection member is used to abut against the workpiece that has reached the lower tolerance limit and form a conductive circuit so that the second light-emitting member emits light.

[0008] When using the above-mentioned detection device, the workpiece to be detected is first placed on the carrier, so that the electrical contacts abut against the lower surface of the workpiece. Then, the support presses the workpiece against the carrier. The first conductive element is electrically connected to the positive terminal of the power supply element. When the tolerance of the workpiece reaches the upper limit, the first detection element abuts against the upper surface of the workpiece, so that the workpiece acts as a conductive element to form a conductive circuit in the detection device. At this time, the first light-emitting element emits light. Finally, the pressing element replaces the support element to press the workpiece against the carrier. The second conductive element is electrically connected to the positive terminal of the power supply element. When the tolerance of the workpiece reaches the lower limit, the second detection element abuts against the upper surface of the workpiece, so that the workpiece acts as a conductive element to form a conductive circuit in the detection device. At this time, the second light-emitting element emits light. In this way, the first detection element is brought into contact with the workpiece that has reached the upper tolerance limit to form a conductive circuit, causing the first light-emitting element to emit light. The brightness of the first light-emitting element determines whether the workpiece has reached the upper tolerance limit. The second detection element is brought into contact with the workpiece that has reached the lower tolerance limit to form a conductive circuit, causing the second light-emitting element to emit light. The brightness of the second light-emitting element determines whether the workpiece has reached the lower tolerance limit. There is no need to frequently adjust the probe extension length of the dial indicator. The brightness of the first and second light-emitting elements determines whether the workpiece is within the preset tolerance range, reducing labor intensity and improving detection efficiency.

[0041] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0042] See also Figure 1 This application provides a detection device 100, including a support component 10, a first detection component 20, and a second detection component 30, for detecting the detection area of ​​a workpiece 200. The workpiece 200 can be a metal part, or it can be a workpiece 200 whose detection area is a metal body, such as a metal back panel of a mobile phone.

[0043] See also Figure 1 , Figure 2 and Figure 3 The carrier component 10 includes a carrier 11, a power supply 12, and an electrical contact 13. The carrier 11 is used to carry the workpiece 200. The power supply 12 is connected to the carrier 11. The electrical contact 13 is embedded in the upper surface of the carrier 11 and electrically connected to the negative electrode of the power supply 12. The electrical contact 13 is used to abut against the workpiece 200 to be inspected. The first detection component 20 includes a support member 21, a first conductive member 22, a first light-emitting member 23, and a first detection member 24. The support member 21 is movably disposed above the carrier member 11 and is used to press the workpiece 200 against the carrier member 11. The first conductive member 22 is connected to the support member 21 and is used to be electrically connected to the positive electrode of the power supply member 12. The first light-emitting member 23 is disposed on the support member 21 and is electrically connected to the first conductive member 22. The first detection member 24 is disposed on the side of the support member 21 facing the carrier member 11 and is electrically connected to the first light-emitting member 23. The first detection member 24 is used to abut against the workpiece 200 that has reached the upper limit of the tolerance and form a conductive circuit so that the first light-emitting member 23 emits light. The second detection component 30 includes a pressing member 31, a second conductive member 32, a second light-emitting member 33, and a second detection member 34. The pressing member 31 is movably disposed above the support member 11 and is used to press the workpiece 200 against the support member 11. The second conductive member 32 is connected to the pressing member 31 and is used to be electrically connected to the positive electrode of the power supply member 12. The second light-emitting member 33 is disposed on the pressing member 31 and is electrically connected to the second conductive member 32. The second detection member 34 is disposed on the side of the pressing member 31 facing the support member 11 and is electrically connected to the second light-emitting member 33. The second detection member 34 is used to abut against the workpiece 200 that has reached the lower tolerance limit and form a conductive circuit so that the second light-emitting member 33 emits light. For example, the power supply member 12 can be a power source, and the first light-emitting member 23 and the second light-emitting member 33 can be small light bulbs.

[0044] When using the aforementioned detection device 100, the workpiece 200 to be detected is first placed on the carrier 11, so that the electrical contact 13 abuts against the lower surface of the workpiece 200. Then, the support 21 presses the workpiece 200 against the carrier 11. The first conductive element 22 is electrically connected to the positive terminal of the power supply 12. When the tolerance of the workpiece 200 reaches the upper limit, the first detection element 24 abuts against the upper surface of the workpiece 200, so that the workpiece 200 acts as a conductive element to form a conductive circuit in the detection device 100. At this time, the first light-emitting element 23 emits light. Finally, the pressing element 31 replaces the support 21 to press the workpiece 200 against the carrier 11. The second conductive element 32 is electrically connected to the positive terminal of the power supply 12. When the tolerance of the workpiece 200 reaches the lower limit, the second detection element 34 abuts against the upper surface of the workpiece 200, so that the workpiece 200 acts as a conductive element to form a conductive circuit in the detection device 100. At this time, the second light-emitting element 33 emits light. In this way, the first detection element 24 abuts against the workpiece 200 that has reached the upper tolerance limit and forms a conductive circuit, causing the first light-emitting element 23 to emit light. The brightness of the first light-emitting element 23 determines whether the workpiece 200 has reached the upper tolerance limit. The second detection element 34 abuts against the workpiece 200 that has reached the lower tolerance limit and forms a conductive circuit, causing the second light-emitting element 33 to emit light. The brightness of the second light-emitting element 33 determines whether the workpiece 200 has reached the lower tolerance limit. There is no need to frequently adjust the probe extension length of the dial indicator. By observing the brightness of the first light-emitting element 23 and the second light-emitting element 33, it is determined whether the workpiece 200 is within the preset tolerance range, which reduces labor intensity and improves detection efficiency.

[0045] It should be noted that, taking the first detection component 20 as an example, when the workpiece 200 reaches the upper tolerance limit, the detection device 100 forms a conductive circuit. The negative terminal of the power supply component 12, the electrical contact 13, the workpiece 200 reaching the upper tolerance limit, the first detection component 24, the first light-emitting component 23, the first conductive component 22, and the positive terminal of the power supply component 12 are sequentially electrically connected to form a conductive circuit. When the second detection component 30 detects the workpiece 200 reaching the lower tolerance limit, its method of forming a conductive circuit is the same as that of the first detection component 20, and will not be repeated here. The workpiece 200 reaching the upper tolerance limit means that the tolerance of the workpiece 200 has reached the maximum value of the preset tolerance range, and the workpiece 200 reaching the lower tolerance limit means that the tolerance of the workpiece 200 has reached the minimum value of the preset tolerance range. The order of the upper tolerance limit detection and the lower tolerance limit detection can be adjusted according to the detection needs.

[0046] In this embodiment, the workpiece 200 has multiple detection areas, and the number of electrical contacts 13, first detection elements 24, second detection elements 34, first light-emitting elements 23 and second light-emitting elements 33 is also multiple and corresponds one-to-one with the multiple detection areas. The multiple electrical contacts 13 are all connected in parallel with the negative terminal of the power supply element 12. The multiple first light-emitting elements 23 and the corresponding first detection elements 24 are connected in series and in parallel with the first conductive element 22. The multiple second light-emitting elements 33 and the corresponding second detection elements 34 are connected in series and in parallel with the second conductive element 32.

[0047] Thus, by setting multiple electrical contacts 13, first detection elements 24, second detection elements 34, first light-emitting elements 23, and second light-emitting elements 33, and having them correspond one-to-one with multiple detection areas, multiple detection areas of the workpiece 200 can be detected.

[0048] See also Figure 4 and Figure 5 In some embodiments, the electrical contact 13 includes a fixing body 131, an electrical contact 132, and a first elastic body 133. The fixing body 131 is disposed on the lower surface of the support member 11 and connected to the support member 11. The electrical contact 132 is movably disposed through the support member 11 and electrically connected to the negative terminal of the power supply member 12, for abutting against the workpiece 200. The two ends of the first elastic body 133 elastically abut against the fixing body 131 and the electrical contact 132, respectively. Exemplarily, the first elastic body 133 can be a spring.

[0049] Thus, by setting the specific structure of the electrical contact 13, when the workpiece 200 is placed on the support member 11, the workpiece 200 abuts against the electrical contact 132 and compresses the first elastic body 133 to the fixed body 131, so that the workpiece 200 and the electrical contact 13 form a flexible contact, avoiding damage to the workpiece 200, thereby ensuring the product quality of the workpiece 200.

[0050] See also Figure 4 and Figure 5In some embodiments, the electrical contact 132 includes a movable part 1321, an electrical contact 1322, and an abutting part 1323. The movable part 1321 is movably disposed through the support member 11 and abuts against the first elastic body 133. The electrical contact 1322 is disposed at one end of the movable part 1321 away from the fixed body 131 and is used to abut against the workpiece 200. The abutting part 1323 is spaced apart from the electrical contact 1322 and is adjacent to the outer periphery of the support member 11 relative to the electrical contact 1322. The first detection element 24, at one end facing the carrier 11, and the second detection element 34, at one end facing the carrier 11, both have a detection portion 2421 and an insulating portion 2422 spaced apart. The insulating portion 2422 serves as a reference for tolerance detection. The detection portion 2421 of the first detection element 24 corresponds to the electrical contact 1322, and the insulating portion 2422 of the first detection element 24 corresponds to the contact portion 1323. Similarly, the detection portion 2421 of the second detection element 34 corresponds to the contact portion 1323, and the insulating portion 2422 of the second detection element 34 corresponds to the electrical contact 1322. Exemplarily, the electrical contact 1322, the contact portion 1323, and the detection portion 2421 can be any conductive block, conductive post, or similar conductive rod capable of conducting electricity, and the insulating portion 2422 can be any insulating block, insulating post, or similar insulating sheet capable of providing insulation.

[0051] Thus, when the first detection element 24 detects a workpiece 200 that has reached the upper tolerance limit, the electrical contact 1322 and the detection element 2421 abut against the upper and lower sides of the workpiece 200, respectively, and the contacting part 1323 and the insulating part 2422 abut against each other, so that the detection device 100 forms a conductive circuit through the workpiece 200 that has reached the upper tolerance limit, thereby realizing the function of detecting the upper tolerance limit of the workpiece 200. Furthermore, when the second detection element 34 detects a workpiece 200 that has reached the lower tolerance limit, the detection element 2421 and the contacting part 1323 abut against each other, and the insulating part 2422 and the electrical contact 1322 abut against the upper and lower sides of the workpiece 200, so that the detection device 100 forms a conductive circuit through the abutting contacting part 1323 and the detection element 2421, thereby realizing the function of detecting the lower tolerance limit of the workpiece 200.

[0052] Please see Figure 4 In some embodiments, the distance between the detection portion 2421 and the electrical contact 1322 of the first detection element 24 is greater than the distance between the insulating portion 2422 and the contact portion 1323 of the first detection element 24, and the distance between the detection portion 2421 and the contact portion 1323 of the second detection element 34 is less than the distance between the insulating portion 2422 and the electrical contact 1322 of the second detection element 34.

[0053] Thus, by setting the distance between the detection part 2421 and the electrical contact 1322 of the first detection element 24 to be greater than the distance between the insulating part 2422 and the contact part 1323 of the first detection element 24, if the workpiece 200 reaches the upper limit of tolerance, the electrical contact 1322 and the detection part 2421 respectively abut against the upper and lower sides of the workpiece 200 and form a conductive circuit. If the workpiece 200 does not reach the upper limit of tolerance, there is a certain gap between the detection part 2421 or one of the electrical contact 1322 and the workpiece 200. At this time, no conductive circuit is formed, and the first light-emitting element 23 turns on or off based on whether a conductive circuit is formed, so as to quickly detect whether the workpiece 200 has reached the upper limit of tolerance. Furthermore, the distance between the detection part 2421 and the contact part 1323 of the second detection element 34 is smaller than the distance between the insulating part 2422 and the electrical contact 1322 of the second detection element 34. When the workpiece 200 reaches the lower tolerance limit, the detection part 2421 and the contact part 1323 abut against each other, and one of the electrical contact 1322 and the insulating part 2422 has a certain movable gap with the workpiece 200. At this time, the detection device 100 forms a conductive circuit through the abutting detection part 2421 and the contact part 1323. When the workpiece 200 does not reach the lower tolerance limit, the electrical contact 1322 and the insulating part 2422 abut against the upper and lower sides of the workpiece 200 respectively. At this time, there is a certain movable gap between the detection part 2421 and the contact part 1323 so that a conductive circuit is not formed. Then, the second light-emitting element 33 turns on or off based on whether a conductive circuit is formed, so as to quickly detect whether the workpiece 200 has reached the lower tolerance limit.

[0054] See also Figure 4 and Figure 6 In some embodiments, both the first detection element 24 and the second detection element 34 include a connecting body 241, a detection body 242, and a second elastic body 243. The connecting body 241 of the first detection element 24 is disposed on the side of the support member 21 opposite to the carrier member 11, and the connecting body 241 of the second detection element 34 is disposed on the side of the pressing member 31 opposite to the carrier member 11. The detection body 242 of the first detection element 24 is movably inserted through the support member 21 and electrically connected to the first light-emitting element 23, and the detection body 242 of the second detection element 34 is movably inserted through the pressing member 31 and electrically connected to the second light-emitting element 33. Both the detection body 242 of the first detection element 24 and the detection body 242 of the second detection element 34 have a detection part 2421 and an insulating part 2422. The two ends of the second elastic body 243 elastically abut against the detection body 242 and the connecting body 241, respectively. For example, the second elastic body 243 can be a spring.

[0055] Thus, by setting the specific structure of the first detection element 24 and the second detection element 34, when the support element 21 and the pressing element 31 respectively drive the first detection element 24 and the second detection element 34 to press the workpiece 200 against the bearing element 11, the first detection element 24 and the second detection element 34 make flexible contact with the workpiece 200, thereby avoiding excessive pressure applied by the first detection element 24 and the second detection element 34 to the workpiece 200 and causing damage to the workpiece 200.

[0056] See also Figure 5 In some embodiments, the carrier 11 includes a carrier body 111, a limiting body 112, and a positioning body 113. The carrier body 111 is connected to the power supply component 12 and the electrical contact component 13 respectively, and the carrier body 111 is used to carry the workpiece 200. The limiting body 112 is disposed on the upper surface of the carrier body 111 and connected to the carrier body 111, and the limiting body 112 is used to limit the workpiece 200. The positioning body 113 is disposed on the carrier body 111 at a distance from the limiting body 112, and the positioning body 113 is used to position the workpiece 200.

[0057] Thus, the workpiece 200 placed on the carrier 111 is limited by the limiting body 112, and the workpiece 200 is positioned by the positioning body 113, so that the workpiece 200 is kept in the preset placement position, thereby making the electric contact 13 stably abut against the detection area of ​​the workpiece 200, and better ensuring the detection accuracy.

[0058] See also Figure 5 In some embodiments, the carrier 11 further includes a plurality of guides 114, which are spaced apart circumferentially on the carrier 111 and are used to guide the support 21 or the pressing member 31.

[0059] Thus, by having multiple guide bodies 114 spaced apart circumferentially along the support body 111, the multiple guide bodies 114 can guide the support member 21 or the pressing member 31 that moves close to the support body 111, so that the first detection member 24 or the second detection member 34 accurately abuts against the detection area of ​​the workpiece 200, thereby improving the detection accuracy.

[0060] Please continue reading. Figure 5 In some embodiments, the end of the guide body 114 away from the carrier body 111 is provided with a guide groove 1141, which is used to guide and limit the support member 21 or the pressing member 31.

[0061] Thus, by providing a guide groove 1141 at the end of the guide body 114 away from the carrier body 111, the guide groove 1141 can guide the support member 21 or the pressing member 31. When the support member 21 or the pressing member 31 moves a certain distance close to the carrier body 111, the bottom of the guide groove 1141 abuts against the support member 21 or the pressing member 31, preventing the first detection member 24 or the second detection member 34 from abutting against the workpiece 200 and continuing to move close to the carrier body 111, thereby ensuring that the pressing force applied by the first detection member 24 or the second detection member 34 to the workpiece 200 is moderate.

[0062] See also Figure 5 In some embodiments, the positioning body 113 includes a first positioning part 1131 and a second positioning part 1132 that are spaced apart, and the first positioning part 1131 and the second positioning part 1132 are used to position the workpiece 200 at different positions.

[0063] In this way, the first positioning part 1131 and the second positioning part 1132 respectively position the workpiece 200 at different positions, so that the workpiece 200 maintains the preset placement orientation, prevents the workpiece 200 from being placed in reverse, and improves the detection accuracy.

[0064] See also Figure 6 In some embodiments, both the first conductive element 22 and the second conductive element 32 include a conductor 221 and a third elastic body 222. The conductor 221 of the first conductive element 22 is movably inserted through the support member 21, with one end of the conductor 221 abutting against the support member 21. The conductor 221 of the second conductive element 32 is movably inserted through the pressing member 31, with one end of the conductor 221 abutting against the pressing member 31. The third elastic body 222 is sleeved on the conductor 221. Both ends of the third elastic body 222 of the first conductive element 22 elastically abut against the other end of the conductor 221 and the support member 21, respectively. Similarly, both ends of the third elastic body 222 of the second conductive element 32 elastically abut against the other end of the conductor 221 and the pressing member 31, respectively. Exemplarily, the conductor 221 can be any conductive rod, conductive part, or similar conductive post capable of conducting electricity, and the third elastic body 222 can be a spring.

[0065] Thus, by setting the specific structure of the first conductive element 22 and the second conductive element 32, the guide body 114 can be flexibly contacted with the power supply element 12, thereby making the guide body 114 stably electrically connected to the positive electrode of the power supply element 12.

[0066] The working process of the aforementioned detection device 100 is roughly as follows:

[0067] First, the workpiece 200 to be tested is placed on the carrier 111. The limiting body 112 and the positioning body 113 limit and position the workpiece 200 so that the workpiece 200 maintains a preset placement position and orientation on the carrier 11. The electrical contact 13 is in flexible contact with the workpiece 200.

[0068] Then, under the guidance of the guide body 114, the support member 21 drives the first detection member 24 to move closer to the carrier member 11. If the workpiece 200 reaches the upper limit of the tolerance, the electrical contact 1322 and the detection part 2421 of the first detection member 24 abut against the upper and lower sides of the workpiece 200 respectively and form a conductive circuit. The first light-emitting member 23 emits light. If the workpiece 200 does not reach the upper limit of the tolerance, the insulating part 2422 of the first detection member 24 and the contact part 1323 abut against each other. There is a certain gap between the detection part 2421 or the electrical contact 1322 of the first detection member 24 and the workpiece 200. At this time, no conductive circuit is formed, and the first light-emitting member 23 does not emit light. Thus, the first light-emitting member 23 turns on and off based on whether a conductive circuit is formed, so as to quickly detect whether the workpiece 200 has reached the upper limit of the tolerance.

[0069] Finally, under the guidance of the guide body 114, the pressing member 31 drives the second detection member 34 to move closer to the carrier member 11. If the workpiece 200 reaches the lower limit of the tolerance, the detection part 2421 and the contact part 1323 of the second detection member 34 abut against each other. There is a certain gap between the electrical contact 1322 and the insulating part 2422 of the second detection member 34 and the workpiece 200. At this time, the detection device 100 forms a conductive circuit through the abutting detection part 2421 and the contact part 1323 of the second detection member 34. The second light-emitting member 3... 3. Light emission: If the workpiece 200 does not reach the lower tolerance limit, the electrical contact 1322 and the insulating part 2422 of the second detection element 34 respectively abut against the upper and lower sides of the workpiece 200. At this time, there is a certain gap between the detection part 2421 and the contact part 1323 of the second detection element 34. At this time, no conductive circuit is formed, and the second light-emitting element 33 does not emit light. Thus, the second light-emitting element 33 turns on and off based on whether a conductive circuit is formed, so as to quickly detect whether the workpiece 200 has reached the lower tolerance limit, reduce labor intensity, and improve detection efficiency.
