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

[0056] In a first aspect, the present invention provides a detection device 100, see Figures 1 to 4 As shown, the detection device 100 includes: a frame assembly 110, a carrier 120, a first driving member 130 and a measuring instrument 150. The carrier 120 is installed on the frame assembly 110, and the test piece 900 can be installed on the carrier 120. The first driving member 130 is installed on the frame assembly 110, and the first driving member 130 is connected to an elastic member 140, and the elastic member 140 can be driven to move along a first direction by the first driving member 130. The measuring instrument 150 can measure the elastic deformation of the elastic member 140 in the first direction.

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

[0058] When 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 connection terminal 911. The test piece 900 is moved to the first inspection station by the carrier 120, and the elastic member 140 is moved in the first direction by the first driving member 130, so that the elastic member 140 moves to the first position and is inserted into the connection terminal 911.

[0059] In order to ensure that the elastic member 140 can be inserted deep into the connection 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 is set to be smaller than the length L of the elastic member 140 in the first direction. Specifically, LA=B, and B=x*C, where C is the standard insertion depth of the connection terminal 911, and x is a proportional coefficient greater than 1. That is, when the elastic member 140 moves to the first position and the test piece 900 is located at the first detection station, the length of the elastic member 140 can meet the requirement of inserting deep into the connection terminal 911.

[0060] Since the elastic member 140 is inserted into the terminal block 911 in the present application, the elastic contraction of the elastic member 140 can be utilized to ensure that the end of the elastic member 140 is kept at the deepest part of the terminal block 911, thereby preventing the elastic force of the elastic member 140 from being too large after insertion due to B (the actual elastic deformation of the elastic member) being much greater than C (the standard insertion depth of the terminal block 911), thereby preventing damage to the interface of the terminal block 911 due to the elastic force of the elastic member 140 being too large after insertion.

[0061] Before the test, the proportional coefficient x can be determined based on the elastic coefficient of the elastic member 140 and the material of the terminal 911. For example, when the elastic coefficient of the elastic member 140 is large, the proportional coefficient x can be set to be smaller to prevent the elastic member 140 from being too hard and generating a large elastic squeezing force during the insertion of the terminal 911, thereby damaging the terminal 911.

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

[0063] Obviously, the greater the elastic deformation D of the elastic member 140 in the first direction when the elastic member 140 is in the first position, the first detection station, and the elastic member 140 remains unchanged, the shallower the depth of the elastic member 140 inserted into the terminal 911. The elastic deformation D1 after the elastic member 140 is inserted into the standard terminal 911 can be used as a reference. When the measured elastic deformation D is at D1±5%, it means that the insertion depth of the terminal 911 meets the requirements. When the measured elastic deformation D is greater than D1+5%, it means that the terminal 911 is too tight or the insertion depth is too shallow, and the insertion depth requirement is not met. When the measured elastic deformation D is less than D1-5%, it means that the terminal 911 is too loose or the depth is too deep, and the insertion depth requirement is also not met.

[0064] In the process of measuring the insertion depth, it is not necessary to use the measuring instrument 150 to measure the internal depth of the terminal 911, and the measurement process is simpler. In the measurement process, the elastic member 140 is used to measure the insertion depth of the terminal 911, which not only causes less damage to the terminal 911, but also can reflect the tightness of the terminal 911, thereby reflecting the smoothness of the insertion of the terminal 911.

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

[0066] That is, before the elastic member 140 is inserted into the connection terminal 911, the torque regulator 170 can be moved by the second driving member 160 to reduce the torque of the fastener (generally a screw) on the connection terminal 911 until the fastener is loosened, so that the connection terminal 911 is opened. Then, the elastic member 140 is moved by the first driving member 130 to insert the elastic member 140 into the connection terminal 911.

[0067] This avoids inserting the elastic member 140 into the unopened connection terminal 911, which causes the measurement result to be unable to reflect the insertion performance of the connection terminal 911 after it is opened.

[0068] A torque screwdriver can be selected as the torque regulator 170 , and screws of different specifications can be adapted by replacing the cutter heads of different specifications.

[0069] In some implementations, the detection device 100 further includes a control module, which has a first test mode. In the first test mode, the control module controls the carrier 120 to move the test piece 900 to the first test station, controls the torque regulator 170 to loosen the fastener until the corresponding terminal 911 is opened, and then controls the first driving member 130 to move the elastic member 140 to the first position. By switching the control module to the first test mode, the automated test of the test device can be achieved, eliminating manual operations and improving the test efficiency.

[0070] In some implementations, the first drive member 130 can also move the elastic member 140 to a second position, and the second position is located on a side of the first position away from the first inspection station. When the elastic member 140 is located at the second position and the test piece 900 is located at the first inspection 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 inspection station, the first drive member 130 moves the elastic member 140 to the first position, and the control module controls the torque regulator 170 to first loosen and then tighten the terminal 911, so that the elastic member 140 is pressed against the terminal 911, and then controls the first drive 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-dropping pulling force of the connection terminal 911 can be tested by moving the elastic member 140 to the second position.

[0072] Obviously, if the elastic member 140 is pulled off from the connection terminal 911 after the elastic member 140 moves to the second position, it means that the anti-detachment pulling force of the connection terminal 911 is less than the elastic pulling force of the elastic member 140 after being stretched to the second position. If the elastic member 140 still does not detach from the connection terminal 911 after moving to the second position, it means that the maximum anti-detachment pulling force of the connection terminal 911 is greater than the elastic pulling force of the elastic member 140 at this time.

[0073] Of course, since the elastic member 140 may slide in the terminal block 911 during the elongation of the elastic member 140, the elastic stretching amount of the elastic member 140 in the first direction after the elastic member 140 moves to the second position can be measured by the measuring instrument 150, and then the tensile force borne by the terminal block 911 can be calculated based on the elastic stretching amount and the elastic coefficient of the elastic member 140.

[0074] During measurement, the second position can be determined based on the required minimum anti-detachment pulling force of the terminal 911 and the elastic coefficient of the elastic member 140. For example, when the minimum anti-detachment pulling force of the terminal 911 is F, it can be calculated based on the elastic coefficient K of the elastic member 140. The second position should satisfy the elastic member 140 being stretched and deformed E, 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 member 140 extending out of the terminal 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 to G≥(L-D1)+E.

[0075] That is to say, the detection device 100 provided by the present 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 separately detecting the insertion depth and anti-detachment performance of the terminal 911 through multiple detection devices 100, the detection difficulty of the terminal 911 is reduced.

[0076] See also 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 installed at the movable end, and 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 be inserted into the wiring terminal 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 installed at the fixed end of the first driving member 130 , and is located at a 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 where the connecting section 141 is connected to the plug-in section 142 .

[0078] See also Figure 2 As shown, the front end of the third driving member 180 is the fixed end of the third driving member 180, and 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 is extended, the third driving member 180 drives the elastic member 140 to move toward the rear side of the detection device 100 along the first direction.

[0079] See also Figure 2 , Figure 5 as well as Fig. 9As shown, the DUT 900 has three terminals 911, and correspondingly three elastic members 140 are connected to the movable end of the third driving member 180. Each elastic member 140 corresponds to a terminal 911, and the three elastic members 140 are respectively inserted into the corresponding terminals 911 by the driving of the third driving member 180.

[0080] It can be understood that the insertion depths that the three connecting terminals 911 can meet can be identified by comparing the deformation amounts of the three elastic members 140 .

[0081] Since the plug-in section 142 extends along the first direction and is perpendicular to the connecting section 141, when the plug-in section 142 is inserted into the wiring terminal 911 and is subjected to the extrusion from the wiring terminal 911, the extrusion force of the wiring terminal 911 will bend the connecting section 141 toward the end away from the wiring terminal 911. When the plug-in section 142 is inserted into the wiring terminal 911 and is subjected to the tension from the wiring terminal 911, the tension of the wiring terminal 911 will bend the connecting section 141 toward the end close to the wiring terminal 911.

[0082] That is, in some implementations, the elastic member 140 is in an L-shaped structure, one end of the elastic member 140 is fixed to the first bracket, and the other end of the elastic member 140 is used to be inserted into the wiring terminal 911. The offset displacement of the connecting section 141 away from one end of the first bracket is measured by the measuring instrument 150, which can reflect the elastic deformation amount of the elastic member 140 in the first direction.

[0083] Among them, 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 expansion and contraction amount of the first driving member 130 from the actually measured offset displacement.

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

[0085] In some implementations, the measuring instrument 150 is an infrared sensor to measure the displacement of the connecting section 141 away from the first bracket. In other implementations, an ultrasonic sensor can also be used as the measuring instrument 150. As long as the displacement of the connecting section 141 away from the active end can be measured, it will be fine.

[0086] See also Figure 2 , Figure 6 as well as Figure 7As shown, in some implementations, the first driving member 130 is installed on the frame assembly through a vertical driving member, wherein the vertical height of the first driving member 130 can be adjusted through the vertical driving member, so that the height of the elastic member 140 changes, and then the first driving member 130 drives the elastic member 140 to move along the first direction, so that the elastic member 140 moves to the first position, and the elastic member 140 is inserted into the connection terminal 911 of the test piece 900. In other words, not only can the position of the elastic member 140 in the front-to-back direction be adjusted by the first driving member 130, but the position of the elastic member 140 in the height direction can also be adjusted by the vertical driving member.

[0087] In some implementations, the elastic member 140 is made of rubber. Rubber has excellent elasticity and can withstand greater pressure and greater tension. After the rubber is inserted into the connection terminal 911, it will not damage the connection terminal 911.

[0088] See also Figure 2 as well as Figures 6 to 9 As shown, in some implementations, a third driving member 180 is further installed on the frame assembly 110, and the third driving member 180 is connected to a shell demolition knife 190, and the third driving member 180 is used to drive the shell demolition knife 190 to insert into the slot of the test piece 900 to separate the 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 driving member 200 , which is also connected to a grabbing assembly 210 . The fourth driving member 200 is configured to drive the grabbing assembly 210 to move toward the test piece 900 so that the grabbing assembly 210 grabs the shell 920 separated from the test piece 900 .

[0090] See also Figure 5 As shown, the test piece 900 in the present application is a switch including a shell 920 and a main body 910, the shell 920 is covered on the outside of the main body 910, one of the shell 920 and the main body 910 is provided with a slot, and the other is provided with a snap-in protrusion, and the snap-in protrusion is snapped into the slot to realize the snap-in connection between the shell 920 and the main body 910. In the present application, by inserting the shell demolition knife 190 into the slot, the snap-in protrusion is separated from the slot, so that the grabbing assembly 210 can grab the separated shell 920, so that the shell 920 is detached from the main body 910. It is avoided that the connection terminal 911 is difficult to be exposed due to the shielding of the shell 920, and the difficulty of inserting the elastic member 140 into the connection terminal 911 is increased.

[0091] In some implementations, in order to make the shell removal knife 190 insert into the slot more smoothly, the end of the removal knife is set to a wedge-shaped structure. When the third driving member 180 drives the shell removal knife 190 to move downward, the top tip of the wedge-shaped structure of the shell removal knife 190 is first inserted into the gap between the shell 920 and the main body 910, so that the shell removal knife 190 can be smoothly inserted into the slot. Then, as the shell removal knife 190 moves further upward, the inclined surface of the shell removal knife 190 will squeeze the shell 920 and the main body 910, so that the gap between the shell 920 and the main body 910 increases, thereby separating the shell 920 from the main body 910.

[0092] See also Figure 7 As shown, in some implementations, the grabbing assembly 210 includes a suction cup 211, and the suction cup 211 is used to absorb the separated shell 920. After the shell removal knife 190 separates the shell 920 from the main body 910, the shell 920 is absorbed by the grabbing assembly 210, and then the grabbing assembly 210 is driven by the fourth driving member 200 to move, and the shell 920 is removed, so that the internal structure of the main body 910 is exposed outside the shell 920, which is convenient for the torque regulator 170 to adjust the torque of the fastener at the terminal 911, and convenient for the elastic member 140 to be inserted into the corresponding terminal 911.

[0093] It is understandable that in other implementations, the grabbing assembly 210 may be a robotic arm structure to grab the housing 920 by clamping.

[0094] Among them, the carrier 120 can also move the test piece 900 to the shelling station, and the control module also has a shelling mode. When the control module switches to the shelling mode, the control module first controls the carrier 120 to move the test piece 900 to the shelling station, and then controls the second driving member 160 to drive the shelling knife 190 under the shelling station to move upward, so that the shelling knife 190 is inserted into the slot of the test piece 900, so that the shell 920 of the test piece 900 is separated from the main body 910, and finally controls the grasping component 210 to grasp the shell 920 of the test piece 900, so that the terminal 911 of the main body 910 is exposed to the external environment, which is convenient for the torque regulator 170 to adjust the fastener at the terminal 911, and convenient for the elastic member 140 to be inserted into the terminal 911.

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

[0096] By toggling the swing switch 912 on the test piece 900 with 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, and the frame-like structure is formed with an opening. When in use, the push plate 222 structure can be driven to move by the fifth driving member 221, so that the opening is set outside the swing switch 912 of the test piece 900, and then the push plate 222 is driven to move back and forth by the fifth driving 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 driving member 221 to drive the push plate 222 to move, so that the opening of the push plate 222 is arranged outside the swing switch 912 of the test piece 900, and then controls the fifth driving member 221 to drive the push plate 222 to move back and forth in a straight line, so as to reciprocately toggle the swing switch 912 of the test piece 900 to detect the mechanical properties of the swing switch 912.

[0098] See also Figure 2 As shown, in some implementations, the frame assembly 110 is further installed with a sixth driving member 230, and one end of the sixth driving member 230 away from the frame assembly 110 is further connected to a probe 240, and the sixth driving member 230 is used to drive the probe 240 to approach or move away from the device under test 900, so that the probe 240 is electrically connected to the device under test 900;

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

[0100] When it is necessary to detect the circuit of the device under test 900, the sixth driving member 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, and the detection circuit can emit a detection current to measure whether there is a circuit fault in the device under test 900.

[0101] See also Figure 2 , Fig. 9 and Fig.11As shown, in some implementations, a positioning clamp is further installed on the frame assembly 110 , and the positioning clamp is used to clamp the test piece 900 on the carrier base 120 from opposite sides of the carrier base 120 to fix the test piece 900 on the carrier base 120 .

[0102] The positioning clamp can not only fix the test piece 900 on the carrier 120, but also realize the positioning of the test piece 900. Figure 2 , Fig. 9 and Fig.11 As shown, the positioning clamp includes a first clamp 250 and a second clamp 260. The first clamp 250 can be positioned from a first side ( Fig.11 The second clamping plate 260 can be moved from the second side (left side) of the carrier seat 120 to the right along the second direction (rightward) toward the carrier seat 120. Fig.11 The first clamping plate 250 and the second clamping plate 260 are relatively close to each other, and the piece to be tested 900 is pushed from opposite sides of the piece to be tested 900 to achieve positioning of the piece to be tested 900 in the second direction.

[0103] See also Fig.11 As shown, in some implementations, positioning clamps are provided at the shelling station and the second inspection station to stabilize the test piece 900 during shelling and shifting inspections. In other implementations, a positioning clamp can also be provided at the first inspection station to stabilize the test piece 900 during the first inspection mode and the second inspection mode.

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

[0105] It should be noted that the first driving member 130 , the second driving member 160 , the third driving member 180 , the fourth driving member 200 , the fifth driving member 221 and the sixth driving member 230 may be electric cylinders, air cylinders or hydraulic cylinders.

[0106] The carrier 120 on the frame assembly 110 can be slidably matched with the guide member 270 to limit the moving direction of the carrier 120. The detection device 100 also includes a sixth driving member 230 for driving the carrier 120 to move, and the sixth driving member 230 drives the carrier 120 to move along the direction in which the guide member 270 extends, so as to move the test piece 900 on the carrier 120 between the shelling station, the first detection station and the second detection station.

[0107] The detection device 100 further includes a plurality of position sensors for detecting whether the carrier 120 accurately transports the test piece 900 to the shelling station, the first detection station and the second detection station.

[0108] See also 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 280 . 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, and the control module can be used to 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, or the control module first analyzes the insertion depth and anti-pull-off performance of the terminal block 911 according to the elastic deformation measured by the measuring instrument 150, and then sends the analyzed insertion depth and anti-pull-off performance to the display screen 280 for display.

[0110] In a second aspect, the present invention further provides a detection method, which uses the above-mentioned detection device 100 to detect the object to be tested 900, and the detection method includes the following steps:

[0111] The test piece 900 is mounted on the carrier 120, and the test piece 900 is moved to the first inspection station;

[0112] Loosen the fastener of the connection 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 connection terminal 911 is determined according to the elastic deformation amount of the elastic member 140 .

[0114] Compared with directly inserting hard metal into the terminal 911, by inserting the elastic member into the terminal 911, when the terminal 911 is blocked, the elastic member 140 can react by elastic deformation, thereby more comprehensively reflecting the insertion performance of the terminal 911 and avoiding the situation where the hard metal directly crushes the terminal 911.

[0115] Furthermore, whether the insertion depth of the connection terminal 911 is too deep can be measured by excessively inserting the elastic member 140 into the connection terminal 911 .

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

[0117] Tighten the fastener of the connection terminal 911 so that the connection terminal 911 clamps the elastic member 140, and controls the elastic member 140 to move to the second position;

[0118] If the elastic member 140 is separated from the connection terminal 911 after moving to the second position or the elastic deformation amount in the first direction is less than the set stretching amount, the anti-pull-off force of the output connection terminal 911 does not meet the requirement;

[0119] If the elastic deformation amount of the elastic member 140 in the first direction after moving to the second position is greater than or equal to the set stretching value, the anti-pull-off force of the output terminal 911 meets the requirement.

[0120] That is, whether the anti-pull-off force of the terminal 911 under tension meets the requirement can be reflected by measuring the elastic deformation of the elastic member 140. The insertion depth measurement and the anti-pull-off force measurement of the terminal 911 can be completed in the same device, and the measurement steps are simpler.

[0121] The set stretching value is determined according to the required minimum anti-pull-off force of the terminal 911 and the elastic coefficient of the elastic member 140 , that is, the set stretching value E should satisfy E=F / K, where F is the minimum anti-pull-off force and K is the elastic coefficient of the elastic member 140 .

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

[0123] Move the test piece 900 to the shelling station;

[0124] Control the shell removal knife 190 to insert into the slot of the device under test 900 to separate the shell 920 of the device under test 900 from the main body 910 of the device under test 900;

[0125] The grabbing assembly 210 is controlled to grab the separated housing 920 and move the housing 920 away from the main body 910 of the device under test 900 .

[0126] That is to say, before the insertion depth test of the connection terminal 911 and the pull-off resistance test of the connection terminal 911 are performed, the shell 920 of the test piece 900 can be separated from the main body 910 of the test piece 900 by inserting the shell demolition knife 190 into the slot, and the shell 920 can be separated by the grabbing component 210. Thus, the connection terminal 911 of the test piece 900 is exposed, which facilitates the insertion of the elastic member 140 into the connection terminal 911, and the insertion depth test and the pull-off resistance test of the connection terminal 911 are completed.

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

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

[0129] Control the toggle assembly 220 to repeatedly toggle 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 circuit conduction status of the device under test 900 is detected by the probe 240 .

[0131] That is to say, in addition to using the elastic member 140 to measure the insertion depth and anti-pull-off force of the terminal 911, it is also possible to measure the mechanical properties of the swing switch 912 and measure the circuit conduction of the device under test 900 through the probe 240, thereby performing a complete test on the device under test 900.

[0132] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
