The wire leads are clamped by the terminal block, so that the terminal block and the wire are electrically connected. Then, the wire is connected to the corresponding circuit of the electrical appliance through the terminal block.

[0003] To ensure proper wiring between the wire and the terminal block, there are requirements regarding the insertion depth of the terminal block. However, the internal space of the terminal block is small, making it difficult to directly measure the insertion depth by inserting measuring instruments inside. Utility Model Content

The first driving member is capable of moving the elastic member along a first direction to a first position. When the carrier is located at the first testing station and the elastic member is at the first position, the elastic member can be inserted into the wiring terminal of the device under test.

[0008] A measuring instrument for measuring the amount of elastic deformation of an elastic element in a first direction.

[0009] In one embodiment, a second drive member is mounted on the frame assembly, and a torque adjuster is mounted on the second drive member. The second drive member is configured to drive the torque adjuster to move, such that the torque adjuster engages with a fastener on a terminal block, and the torque adjuster is used to adjust the torque of the fastener.

[0010] In one embodiment, the detection device further includes a control module, the control module having a first test mode;

[0011] In the first test mode, the control module controls the carrier to move the test piece to the first test station, controls the torque adjuster to loosen the fastener so that the corresponding terminal is opened, and then controls the first drive to move the elastic element to the first position.

[0012] In one embodiment, the first driving member can also move the elastic member to a second position, the second position being located on the side of the first position away from the first detection station. When the elastic member is in the second position and the test piece is in the first detection station, the distance between the end of the elastic member away from the terminal and the terminal is greater than the original length of the elastic member.

[0013] The control module also has a second test mode;

[0014] In the second test mode, the control module controls the carrier to move the test piece to the first test station, the first drive unit moves the elastic element to the first position, the control torque adjuster first loosens and then tightens the terminal block so that the elastic element is pressed into the terminal block, and then controls the first drive unit to move the elastic element to the second position.

[0015] In one embodiment, the first driving member has a fixed end and a movable end, the elastic member is mounted on the movable end, the elastic member includes a plug-in section and a connecting section that are perpendicular to each other, wherein the plug-in section extends along a first direction, and one end of the plug-in section is used to insert into a terminal block, the other end of the plug-in section is connected to the connecting section, and the connecting section is fixed to the movable end; the measuring instrument is mounted on the fixed end of the first driving member, and the measuring instrument is located on the side of the elastic member away from the first detection station, the measuring instrument is used to measure the offset displacement of the connecting section and the end connected to the plug-in section.

[0016] In one embodiment, the frame assembly is further equipped with a second drive member connected to a shell-removing knife. The second drive member is used to drive the shell-removing knife to insert into a slot of the test piece to separate the outer shell of the test piece from the body of the test piece. The frame assembly is also equipped with a third drive member connected to a gripping component. The third drive member is configured to drive the gripping component to move toward the test piece so that the gripping component can grip the outer shell separated from the test piece.

[0017] In one embodiment, the gripping component includes a suction cup for adsorbing the separated outer shell.

[0018] In one embodiment, the detection device further includes a toggle assembly, which includes a fourth drive member and a push plate. The fourth drive member is mounted on the frame assembly, and the push plate is connected to the fourth drive member. The fourth drive member is configured to drive the push plate closer to or away from the carrier seat, so that the push plate toggles a swing switch on the test piece.

[0019] In one embodiment, the frame assembly is further equipped with a fifth driving member, and a probe is connected to one end of the fifth driving member away from the frame assembly. The fifth driving member is used to drive the probe to approach or move away from the test piece, so that the probe is electrically connected to the test piece. The detection device further includes a detection circuit, which is electrically connected to the probe.

[0020] In one embodiment, the frame assembly is further equipped with positioning clamps for clamping the test piece on the carrier from opposite sides of the carrier, thereby fixing the test piece on the carrier.

[0021] Secondly, this utility model also provides a detection method, which uses the above-mentioned detection device to detect the test piece, the detection method comprising the following steps:

[0022] The test piece is mounted on the carrier and moved to the first testing station;

[0023] Loosen the fasteners of the terminal block and move the elastic element to the first position to obtain the elastic deformation of the elastic element in the first direction at this time.

[0024] The insertion depth performance of the terminal block is determined by the amount of elastic deformation of the elastic element.

[0025] In one implementation, the following steps are also included:

[0026] Tighten the fasteners on the terminals to clamp the elastic element;

[0027] Control the elastic element to move to the second position;

[0028] If the elastic element moves to the second position and then disengages from the terminal, or if the elastic deformation in the first direction is less than the set stretching amount, the anti-pull-out force of the output terminal does not meet the requirements.

[0029] If the elastic deformation in the first direction is greater than or equal to the set stretching amount after the elastic element moves to the second position, the pull-out force of the output terminal meets the requirements.

[0030] In one embodiment, before moving the carrier to the first inspection station, the inspection method further includes the following steps:

[0031] Move the part to be tested to the shell removal station;

[0037] The control probe is electrically connected to the device under test (DUT), and the continuity of the DUT's circuit is detected by the probe.

[0038] Compared with the prior art, the advantages of this utility model are that by moving the elastic element to the first position, the elastic element is inserted into the terminal block along the first direction, thereby reflecting the insertion depth of the terminal block based on the elastic deformation of the elastic element. The measurement process is simple and quick. Moreover, because the elastic element is elastic, it can reflect the terminal blockage by the degree of elastic deformation of the elastic element, and can reflect the excessive insertion depth of the terminal block by the degree of elastic deformation of the elastic element, thus directly reflecting the defects of the terminal block in terms of insertion depth.

[0054] 900, Component under test; 910, Main body; 911, Terminal block; 912, Swing switch; 920, Housing. Detailed Implementation

[0055] The present invention will be further described below with reference to the accompanying drawings.

[0056] Firstly, this utility model provides a detection device 100, see [link to relevant documentation]. Figures 1 to 4 As shown, the testing device 100 includes: a frame assembly 110, a carrier 120, a first drive member 130, and a measuring instrument 150. The carrier 120 is mounted on the frame assembly 110 and can mount the test piece 900 on the carrier 120. The first drive member 130 is mounted on the frame assembly 110 and is connected to an elastic member 140, enabling the first drive member 130 to drive the elastic member 140 to move along a first direction. The measuring instrument 150 can measure the amount of elastic deformation of the elastic member 140 in the first direction.

[0057] See Figure 5 As shown, the device under test 900 can be a junction box with terminals 911, or a switch, circuit breaker or other electrical component with terminals 911.

[0058] In use, the test piece 900 can be mounted on the carrier 120, and the fasteners on the test piece 900 can be loosened to open the terminal block 911. The test piece 900 is moved to the first testing station via the carrier 120, and then the elastic member 140 is moved along the first direction by the first drive member 130, so that the elastic member 140 moves to the first position and is inserted into the terminal block 911.

[0059] To ensure that the elastic element 140 can be inserted deeply into the terminal 911, the gap between the first position and the first detection station can be adjusted. For example, the gap A between the first position and the first detection station can be set to be less than the length L of the elastic element 140 in the first direction. Specifically, LA = B, and B = x * C, where C is the standard insertion depth of the terminal 911, and x is a proportionality coefficient greater than 1. That is, when the elastic element 140 moves to the first position and the test piece 900 is located at the first detection station, the length of the elastic element 140 can meet the requirement of being inserted deeply into the terminal 911.

[0060] Since this application uses an elastic element 140 inserted into the terminal 911, the elastic contraction of the elastic element 140 can be used to keep the end of the elastic element 140 exactly at the deepest point of the terminal 911, avoiding damage to the interface of the terminal 911 caused by excessive elastic force after the elastic element 140 is inserted due to B (the actual deformation elasticity of the elastic element) being much greater than C (the standard insertion depth of the terminal 911).

[0061] Before the test, the proportional coefficient x can be determined according to the elastic coefficient of the elastic element 140 and the material of the terminal 911. For example, when the elastic coefficient of the elastic element 140 is large, the proportional coefficient x can be set to a smaller value to avoid the elastic element 140 being too hard and generating a large elastic squeezing force during the insertion of the terminal 911, which would damage the terminal 911.

[0062] During the test, the elastic deformation D of the elastic element 140 in the first direction is measured by the measuring instrument 150. The deformation of the elastic element 140 in the first direction can reflect the insertion depth of the elastic element 140 and the squeezing force of the elastic element 140 on the terminal 911.

[0063] Obviously, when the first position, the first detection station, and the elastic element 140 remain unchanged, the larger the elastic deformation D of the elastic element 140 in the first direction, the shallower the insertion depth of the elastic element 140 into the terminal 911. Using the elastic deformation D1 of the elastic element 140 after insertion into the standard terminal 911 as a benchmark, when the measured elastic deformation D is within D1 ± 5%, it indicates that the insertion depth of the terminal 911 meets the requirements. When the measured elastic deformation D is greater than D1 + 5%, it indicates that the terminal 911 is too tight or the insertion depth is too shallow, failing to meet the insertion depth requirements. When the measured elastic deformation D is less than D1 - 5%, it indicates that the terminal 911 is too loose or the insertion depth is too deep, also failing to meet the insertion depth requirements.

[0064] During the measurement of insertion depth, it is not necessary to measure the internal depth of the terminal 911 with the measuring instrument 150, making the measurement process simpler. Furthermore, the use of the elastic element 140 to measure the insertion depth of the terminal 911 during the measurement process not only minimizes damage to the terminal 911 but also reflects the tightness of the terminal 911, thereby demonstrating the smoothness of the insertion of the terminal 911.

[0065] See Figure 2 , Figure 6 and Figure 7 As shown, in some implementations, a second drive unit 160 is also installed on the frame assembly 110. A torque adjuster 170 is installed on the second drive unit 160. The second drive unit 160 is configured to drive the torque adjuster 170 to move, so that the torque adjuster 170 engages with the fastener on the terminal block 911. The torque adjuster 170 is used to adjust the torque of the fastener.

[0066] In other words, before inserting the elastic element 140 into the terminal 911, the torque adjuster 170 can be moved by the second drive element 160 to reduce the torque of the fastener (usually a screw) on the terminal 911 until the fastener is loosened, thus opening the terminal 911. Then, the elastic element 140 is moved by the first drive element 130 to insert the elastic element 140 into the terminal 911.

[0067] This avoids inserting the elastic element 140 into the unopened terminal 911, which would prevent the measurement results from reflecting the insertion performance of the terminal 911 after it is opened.

[0068] Among them, a torque screwdriver can be selected as the torque adjuster 170, and different sizes of screws can be adapted by changing different sizes of the screw head.

[0069] In some implementations, the testing device 100 also includes a control module. The control module has a first testing mode. In the first testing mode, the control module controls the carrier 120 to move the workpiece 900 to the first testing station, controls the torque adjuster 170 to loosen the fasteners until the corresponding terminal 911 is opened, and then controls the first drive component 130 to move the elastic component 140 to the first position. By switching the control module to the first testing mode, automated testing of the testing device can be achieved, eliminating manual operation and improving testing efficiency.

[0070] In some implementations, the first driving member 130 can also move the elastic member 140 to a second position. The second position is located on the side of the first position away from the first detection station. When the elastic member 140 is in the second position and the test piece 900 is in the first detection station, the distance between the end of the elastic member 140 away from the terminal 911 and the terminal 911 is greater than the original length of the elastic member 140. The control module also has a second test mode. In the second test mode, the control module controls the carrier 120 to move the test piece 900 to the first detection station, the first driving member 130 to move the elastic member 140 to the first position, and the control module controls the torque adjuster 170 to first loosen and then tighten the terminal 911 so that the elastic member 140 is pressed into the terminal 911. Then, the control module controls the first driving member 130 to move the elastic member 140 to the second position.

[0071] When the control module is switched to the second test mode, the anti-detachment pull force of the terminal 911 can be tested by moving the elastic element 140 to the second position.

[0072] Obviously, if the elastic element 140 is pulled out of the terminal 911 after moving to the second position, it indicates that the anti-disengagement pull force of the terminal 911 is less than the elastic pull force of the elastic element 140 after being stretched to the second position. However, if the elastic element 140 does not disengage from the terminal 911 after moving to the second position, it indicates that the maximum anti-disengagement pull force of the terminal 911 is greater than the elastic pull force of the elastic element 140 at this time.

[0073] Of course, since the elastic element 140 may slide in the terminal 911 during the stretching process, the elastic stretch of the elastic element 140 in the first direction can be measured by the measuring instrument 150 after the elastic element 140 moves to the second position. Then, the tension borne by the terminal 911 can be calculated based on the elastic stretch and the elastic coefficient of the elastic element 140.

[0074] During measurement, the second position can be determined based on the minimum anti-detachment pull force required by the terminal block 911 and the elastic coefficient of the elastic element 140. For example, when the minimum anti-detachment pull force of the terminal block 911 is F, the second position should satisfy the stretching deformation E of the elastic element 140, where E = F / K. Then, the distance G between the second position and the first detection station can be obtained, and G ≥ (LD) + E, where LD is the length of the elastic element 140 extending beyond the terminal block 911. In some implementations, the distance between the second position and the first detection station can be determined based on D measured in the first detection mode. In other implementations, G can also be set as G ≥ (L-D1) + E.

[0075] In other words, the detection device 100 provided in this application can not only detect the insertion depth of the terminal 911, but also detect the anti-detachment performance of the terminal 911. Compared with the previous method of using multiple detection devices 100 to detect the insertion depth and anti-detachment performance of the terminal 911 separately, this reduces the detection difficulty of the terminal 911.

[0076] See Figure 5 As shown, in some implementations, the first driving member 130 has a fixed end and a movable end, the elastic member 140 is mounted on the movable end, the elastic member 140 includes a plug-in section 142 and a connecting section 141 that are perpendicular to each other, wherein the plug-in section 142 extends along a first direction, and one end of the plug-in section 142 is used to insert into the terminal block 911, and the other end of the plug-in section 142 is connected to the connecting section 141, and the connecting section 141 is fixed to the movable end;

[0077] The measuring instrument 150 is mounted on the fixed end of the first driving member 130, and the measuring instrument 150 is located on the side of the elastic member 140 away from the first detection station. The measuring instrument 150 is used to measure the offset displacement of the end of the connecting section 141 connected to the plug section 142.

[0078] See Figure 2 As shown, the front end of the third driving member 180 is the fixed end of the third driving member 180, while the rear end of the third driving member 180 is the movable end of the third driving member 180. When the third driving member 180 extends, the third driving member 180 drives the elastic member 140 to move towards the rear side of the detection device 100 along the first direction.

[0079] See Figure 2 , Figure 5 as well as Figure 9As shown, the device under test 900 has three terminals 911, and three elastic elements 140 are connected to the movable end of the third drive element 180. Each elastic element 140 corresponds to one terminal 911, and the three elastic elements 140 are inserted into the corresponding terminals 911 by the drive of the third drive element 180.

[0080] Understandably, the insertion depth that the three terminals 911 can satisfy can be identified by comparing the deformation of the three elastic elements 140.

[0081] Since the plug segment 142 extends along the first direction and is perpendicular to the connecting segment 141, when the plug segment 142 is inserted into the terminal 911 and subjected to compression from the terminal 911, the compression force of the terminal 911 will bend the connecting segment 141 toward the end away from the terminal 911. When the plug segment 142 is inserted into the terminal 911 and subjected to tension from the terminal 911, the tension force of the terminal 911 will bend the connecting segment 141 toward the end closer to the terminal 911.

[0082] In other words, in some implementations, the elastic element 140 has an L-shaped structure, with one end of the elastic element 140 fixed to the first bracket and the other end of the elastic element 140 used for insertion into the terminal block 911. By measuring the offset displacement of the end of the connecting section 141 away from the first bracket using the measuring instrument 150, the amount of elastic deformation of the elastic element 140 in the first direction can be reflected.

[0083] Since the measuring instrument 150 is installed at the fixed end of the first driving member 130 and the elastic member 140 is installed at the movable end of the first driving member 130, when the measuring instrument 150 measures the elastic deformation of the elastic member 140, it is necessary to subtract or add the actual measured offset displacement to the extension and contraction of the first driving member 130.

[0084] In some implementations, the measuring instrument 150 and the elastic element 140 can both be installed on the movable end of the first driving member 130, so that the offset displacement of the end of the connecting segment 141 measured by the measuring instrument 150 is equal to the elastic deformation of the elastic element 140.

[0085] In some implementations, the measuring instrument 150 is an infrared sensor to measure the offset displacement of the connecting segment 141 away from the first support. In other implementations, an ultrasonic sensor can also be used as the measuring instrument 150. The key is to be able to measure the amount of offset displacement of the connecting segment 141 away from the movable end.

[0086] See Figure 2 , Figure 6 as well as Figure 7As shown, in some implementations, the first drive member 130 is mounted on the frame assembly via a vertical drive member. The vertical height of the first drive member 130 can be adjusted via the vertical drive assembly, changing the height of the elastic member 140. Then, the first drive member 130 drives the elastic member 140 to move along a first direction, moving it to a first position, whereby the elastic member 140 is inserted into the terminal 911 of the test piece 900. In other words, not only can the position of the elastic member 140 in the front-back direction be adjusted via the first drive member 130, but the position of the elastic member 140 in the height direction can also be adjusted using the vertical drive member.

[0087] In some implementations, the elastic element 140 is made of rubber. Rubber has excellent elasticity and can withstand large pressure and tensile force. Furthermore, the rubber will not damage the terminal 911 after it is inserted into the terminal.

[0088] See Figure 2 as well as Figures 6 to 9 As shown, in some implementations, a third drive unit 180 is also installed on the frame assembly 110. The third drive unit 180 is connected to a shell-removing knife 190. The third drive unit 180 is used to drive the shell-removing knife 190 to insert into the slot of the test piece 900 so as to separate the outer shell 920 of the test piece 900 from the main body 910 of the test piece 900.

[0089] The frame assembly 110 is also equipped with a fourth drive unit 200, which is also connected to a gripping assembly 210. The fourth drive unit 200 is configured to drive the gripping assembly 210 to move toward the test piece 900 so that the gripping assembly 210 can grip the outer shell 920 separated from the test piece 900.

[0090] See Figure 5 As shown, the test component 900 in this application is a switch including a housing 920 and a main body 910. The housing 920 covers the outside of the main body 910. One of the housing 920 and the main body 910 has a slot, and the other has a snap-fit ​​protrusion. The snap-fit ​​protrusion engages with the slot to achieve a snap-fit ​​connection between the housing 920 and the main body 910. In this application, by inserting the shell-removing tool 190 into the slot, the snap-fit ​​protrusion separates from the slot, allowing the gripping component 210 to grip the separated housing 920, thus detaching the housing 920 from the main body 910. This avoids the difficulty of exposing the wiring terminal 911 due to the housing 920 obstructing the view, thus preventing the elastic member 140 from being inserted into the wiring terminal 911.

[0091] In some implementations, to facilitate smoother insertion of the shell-opening blade 190 into the slot, the end of the blade is designed as a wedge shape. When the third drive unit 180 drives the shell-opening blade 190 downward, the tip of the wedge-shaped structure of the shell-opening blade 190 first inserts into the gap between the outer shell 920 and the main body 910, allowing the shell-opening blade 190 to smoothly insert into the slot. Then, as the shell-opening blade 190 moves further upward, the inclined surface of the shell-opening blade 190 will compress the outer shell 920 and the main body 910, increasing the gap between them and thus separating the outer shell 920 from the main body 910.

[0092] See Figure 7 As shown, in some implementations, the gripping component 210 includes a suction cup 211 for adsorbing the separated outer shell 920. After the shell-removing knife 190 separates the outer shell 920 from the main body 910, the gripping component 210 adsorbs the outer shell 920, and then the fourth driving member 200 drives the gripping component 210 to move, moving the outer shell 920 away, so that the internal structure of the main body 910 is exposed outside the outer shell 920. This facilitates the torque adjuster 170 to adjust the torque of the fastener at the terminal 911, and facilitates the insertion of the elastic member 140 into the corresponding terminal 911.

[0093] Understandably, in some other implementations, the gripping component 210 can be a robotic arm structure to grip the housing 920 by clamping.

[0094] The carrier 120 can also move the test piece 900 to the unpacking station. The control module also has a shell-removal mode. When the control module switches to the shell-removal mode, the control module first controls the carrier 120 to move the test piece 900 to the unpacking station, and then controls the second drive unit 160 to drive the shell-removal knife 190 below the unpacking station to move upward, so that the shell-removal knife 190 is inserted into the slot of the test piece 900, so that the outer shell 920 of the test piece 900 is separated from the main body 910. Finally, the gripping component 210 is controlled to grip the outer shell 920 of the test piece 900, so that the wiring terminal 911 of the main body 910 is exposed to the external environment, which facilitates the torque adjuster 170 to adjust the fasteners at the wiring terminal 911, and facilitates the insertion of the elastic member 140 into the wiring terminal 911.

[0095] See Figure 2 , Figure 5 ,as well as Figure 8As shown, in some implementations, the detection device 100 further includes a toggle assembly 220, which includes a fifth drive member 221 and a push plate 222. The fifth drive member 221 is mounted on the frame assembly 110, and the push plate 222 is connected to the fifth drive member 221. The fifth drive member 221 is configured to drive the push plate 222 to move closer to or away from the carrier 120, so that the push plate 222 toggle the swing switch 912 on the test piece 900.

[0096] By toggling the swing switch 912 on the test piece 900 using the toggle assembly 220, it can be detected whether the swing switch 912 can swing normally. In some implementations, the push plate 222 has a frame-like structure with an opening. During use, the push plate 222 can be moved by the fifth drive member 221, thereby covering the opening around the swing switch 912 on the test piece 900. Then, the push plate 222 is moved back and forth by the fifth drive member 221 to realize the reciprocating swing of the swing switch 912.

[0097] The control module also has a swing detection mode. When the control module switches to the swing detection mode, the control module controls the carrier 120 to move the test piece 900 to the second detection station, and then controls the fifth drive component 221 to drive the push plate 222 to move, so that the opening of the push plate 222 is fitted over the swing switch 912 of the test piece 900. Then, the fifth drive component 221 is controlled to drive the push plate 222 to move back and forth linearly, so as to repeatedly turn the swing switch 912 of the test piece 900 to detect the mechanical performance of the swing switch 912.

[0098] See Figure 2 As shown, in some implementations, the frame assembly 110 is also equipped with a sixth drive member 230. The end of the sixth drive member 230 away from the frame assembly 110 is also connected to a probe 240. The sixth drive member 230 is used to drive the probe 240 to approach or move away from the test piece 900 so that the probe 240 is electrically connected to the test piece 900.

[0099] The detection device 100 also includes a detection circuit, which is electrically connected to the probe 240.

[0100] When it is necessary to test the circuit of the device under test 900, the sixth driving device 230 can drive the probe 240 to move, so that the probe 240 moves to be electrically connected to the device under test 900, thereby making the device under test 900 electrically connected to the detection circuit through the probe 240. The detection circuit can then send out a detection current to measure whether there is a circuit fault in the device under test 900.

[0101] See Figure 2 , Figure 9 and Figure 11As shown, in some implementations, the frame assembly 110 is also equipped with positioning clamps, which are used to clamp the test piece 900 on the carrier 120 from opposite sides of the carrier 120, and fix the test piece 900 on the carrier 120.

[0102] The positioning clamp not only secures the part under test 900 to the carrier 120, but also enables the positioning of the part under test 900. For example... Figure 2 , Figure 9 and Figure 11 As shown, the positioning clamp includes a first clamp 250 and a second clamp 260. The first clamp 250 can be positioned from the first side of the carrier 120. Figure 11 The second clamp 260 can be positioned from the second side of the carrier 120 (left side) along the second direction (to the right). Figure 11 The test piece 900 is pushed from the opposite sides of the test piece 900 along the second direction (to the left) toward the carrier 120. When the first clamping plate 250 and the second clamping plate 260 are relatively close, the test piece 900 is positioned in the second direction.

[0103] See Figure 11 As shown, in some implementations, positioning clamps are provided at the shell removal station and the second inspection station to stabilize the test piece 900 during shell removal and tossing inspection. In other implementations, positioning clamps are also provided at the first inspection station to stabilize the test piece 900 in both the first and second inspection modes.

[0104] In some implementations, the second direction is perpendicular to the first direction.

[0105] It should be noted that the first drive component 130, the second drive component 160, the third drive component 180, the fourth drive component 200, the fifth drive component 221, and the sixth drive component 230 can be electric cylinders, pneumatic cylinders, or hydraulic cylinders.

[0106] The frame assembly 110 includes a carrier 120 that can slide with the guide member 270 to define the direction of movement of the carrier 120. The testing device 100 also includes a sixth drive member 230 that drives the carrier 120 to move along the direction of extension of the guide member 270, thereby moving the test piece 900 on the carrier 120 between the shell removal station, the first testing station, and the second testing station.

[0107] The testing device 100 also includes several position sensors for detecting whether the carrier 120 accurately transports the test piece 900 to the unpacking station, the first testing station, and the second testing station.

[0108] See Figure 7 As shown, in some implementations, the detection device 100 further includes a display screen 280, which is electrically connected to the control module. The control module is also connected to the detection circuit to display various detection data obtained by the detection circuit on the display screen 280.

[0109] In some implementations, the control module is also electrically connected to the measuring instrument 150. The control module can send the elastic deformation measured by the measuring instrument 150 in the first detection mode and the elastic deformation measured by the measuring instrument 150 in the second detection mode to the display screen 280 for display. Alternatively, the control module can first analyze the insertion depth and anti-pull-out performance of the terminal 911 based on the elastic deformation measured by the measuring instrument 150, and then send the analyzed insertion depth and anti-pull-out performance to the display screen 280 for display.

[0110] Secondly, this utility model also provides a detection method, which uses the aforementioned detection device 100 to detect the test piece 900. The detection method includes the following steps:

[0111] Install the test piece 900 on the carrier 120 and move the test piece 900 to the first testing station;

[0112] Loosen the fasteners of terminal 911 and move the elastic member 140 to the first position to obtain the elastic deformation amount of the elastic member 140 in the first direction at this time.

[0113] The insertion depth performance of the terminal 911 is determined based on the elastic deformation of the elastic element 140.

[0114] Compared to directly inserting hard metal into the terminal 911, by inserting an elastic element into the terminal 911, the terminal 911 can react by elastic deformation of the elastic element 140 when blockage occurs, thus more comprehensively reflecting the insertion performance of the terminal 911 and avoiding the situation where hard metal directly crushes the terminal 911.

[0115] Furthermore, it is possible to measure whether the insertion depth of the terminal 911 is too deep by excessively inserting the elastic element 140 into the terminal 911.

[0116] In some implementations, the detection method also includes the following steps:

[0117] Tighten the fasteners of the terminal block 911 so that the terminal block 911 clamps the elastic member 140, and control the elastic member 140 to move to the second position;

[0118] If the elastic element 140 moves to the second position and disengages from the terminal 911, or if the elastic deformation in the first direction is less than the set stretching amount, the anti-pull-out force of the output terminal 911 does not meet the requirements.

[0119] If the elastic deformation in the first direction is greater than or equal to the set stretching value after the elastic element 140 moves to the second position, the pull-out force of the output terminal 911 meets the requirements.

[0120] In other words, the amount of elastic deformation of the elastic element 140 is used to determine whether the anti-pull-out force of the terminal 911 under tension meets the requirements. This allows the insertion depth measurement and anti-pull-out force measurement of the terminal 911 to be completed in the same device, simplifying the measurement process.

[0121] The set tension value is determined based on the minimum anti-pull-out force required by the terminal block 911 and the elastic coefficient of the elastic element 140. That is, the set tension value E should satisfy E=F / K, where F is the minimum anti-pull-out force and K is the elastic coefficient of the elastic element 140.

[0122] In some implementations, the inspection method further includes the following steps before moving the carrier 120 to the first inspection station:

[0123] Move part 900 to the unpacking station;

[0124] The shell removal knife 190 is inserted into the slot of the test piece 900 to separate the outer shell 920 of the test piece 900 from the main body 910 of the test piece 900.

[0125] The gripping component 210 grips the separated outer shell 920 and moves the outer shell 920 away from the main body 910 of the test piece 900.

[0126] In other words, before performing the insertion depth test and the pull-out force test of the terminal 911, the shell 920 of the component under test 900 can be separated from the main body 910 of the component under test 900 by inserting the shell removal tool 190 into the slot, and the shell 920 can be separated by the gripping component 210. This exposes the terminal 911 of the component under test 900, making it easier for the elastic member 140 to be inserted into the terminal 911, thus completing the insertion depth test and the pull-out force test of the terminal 911.

[0127] In some implementations, the detection method also includes the following steps:

[0128] Move carrier 120 to the second inspection station;

[0129] The control toggle assembly 220 repeatedly toggles the swing switch 912 of the test piece 900;

[0130] The control probe 240 is electrically connected to the device under test 900, and the continuity of the circuit of the device under test 900 is detected by the probe 240.

[0131] In other words, in addition to using the elastic element 140 to measure the insertion depth and anti-pull-out force of the terminal 911, it can also measure the mechanical properties of the swing switch 912 and measure the circuit continuity of the test piece 900 through the probe 240, thereby performing a complete test on the test piece 900.
