DETAILED DESCRIPTION
[0030] The following will be described in detail in combination with the accompanying Figures 1-2 The present application will be further described in detail.
[0031] The embodiment of the present application discloses a sensor detection device.
[0032] Referring to Figure 1 The sensor detection device comprises an L-shaped frame body 2, the frame body 2 is provided with a positioning groove 21 for placing a sensor shell, and the frame body 2 is further provided with an alarm (not shown in the figure) electrically connected to a control system.
[0033] Unit detection groups are arranged on both sides of the frame body 2, and the two ends of the copper sheet in the sensor shell correspond to a group of unit detection groups respectively, and the unit detection group comprises a continuity detection part 31 and a length detection part.
[0034] Referring to Figure 1 and Figure 2, the conduction detection part 31 comprises a sliding block 311 sliding on the frame 2 and a cylinder 312 bolted on the frame 2 and electrically connected to the control system. The frame 2 is provided with a sliding groove 22, the sliding block 311 extends into the sliding groove 22 and is in sliding cooperation with the sliding groove 22, the cross section of the sliding cooperation position of the sliding block 311 and the sliding groove 22 is dovetail-shaped, and the sliding block 311 is coated with polytetrafluoroethylene.
[0035] With reference to Figure 1 and Figure 2 , the piston rod of the cylinder 312 is threadedly connected to the sliding block 311 and is used to drive the sliding block 311 to approach or move away from the copper sheet, and the sliding block 311 is welded with wires 313 connected to the power supply. Since the copper sheet is usually arranged with multiple copper sheets in the sensor shell, the wires 313 are also welded with multiple wires 313 on the sliding block 311 and correspond to the copper sheets one by one.
[0036] With reference to Figure 1 and Figure 2 , the long and short detection part comprises a laser emitter 321 and a laser receiver 322 threadedly connected to the sliding block 311 and electrically connected to the control system, the emitting end of the laser emitter 321 faces the receiving end of the laser receiver 322, and the top of the sliding block 311 is open relative to the position between the laser emitter 321 and the laser receiver 322.
[0037] With reference to Figure 1 and Figure 2 , one side of the sliding block 311 facing the copper sheet is provided with a sliding hole 4, each wire 313 corresponds to one sliding hole 4, and the sliding block 311 is bolted with a sealing plate 5 used to seal the sliding hole 4, and the cross section of the sliding hole 4 is oval.
[0038] A detection guide needle 6 between the laser emitter 321 and the laser receiver 322 slides in the sliding hole 4, the detection guide needle 6 is integrally formed with a top sheet 7 sliding in the sliding hole 4, the cross section of the top sheet 7 is oval, and the top sheet 7 is supported by a compression spring 8 between the sealing end of the sliding hole 4.
[0039] With reference to Figure 1 and Figure 2 , one end of the detection guide needle 6 slides out of the sealing plate 5 and is used to contact the corresponding copper sheet, the other end of the detection guide needle 6 slides out of the sliding hole 4 and is used to contact the wire 313, and the detection guide needle 6 is provided with a light hole 9 for the laser to pass through.
[0040] With reference to Figure 1 and Figure 2 , during detection, the worker manually places the sensor shell to be detected in the positioning groove 21, and then starts the cylinder 312 through the control system, the piston rod of the cylinder 312 extends, and then drives the sliding block 311 to approach the sensor shell.
[0041] With reference to Figure 1 and Figure 2The detection guide needle 6 on the sliding block 311 first contacts the end of the copper sheet, and then in the process of the piston rod of the cylinder 312 continuing to extend, the detection guide needle 6 is pushed back into the sliding hole 4 by the copper sheet in the opposite direction, the pressing spring 8 is pressed by the top sheet 7 matched with the closed end of the sliding hole 4, until the piston rod of the cylinder 312 is completely extended.
[0042] At this time, the other end of the detection guide needle 6 relative to the copper sheet should be in contact with the corresponding wire 313, that is, the power supply, the wire 313, the copper sheet and the detection guide needle 6 form a closed circuit, and there is current passing through the circuit.
[0043] If the copper sheet has a problem in conductivity, the above-mentioned circuit is in an open state, and the control system cannot detect that there is current passing through, at which time the alarm will issue an alarm.
[0044] Referring to Figure 1 and Figure 2 , by the same reason, when the piston rod of the cylinder 312 is completely extended, the light hole 9 on the detection guide needle 6 should be able to allow the laser emitted by the laser emitter 321 to pass through and be received by the laser receiver 322, if the copper sheet has a problem in length, the light hole 9 deviates from the accurate position, so that the laser emitted by the laser emitter 321 cannot be received by the laser receiver 322, and the alarm will also issue an alarm.
[0045] That is to say, by the above design, the conductivity detection and length detection of the copper sheet are integrated into the same device, which greatly shortens the time consumed in detection, and further improves the production efficiency.
[0046] The implementation principle of the sensor detection device in the embodiment of the application is as follows: during detection, a worker manually places a sensor shell to be detected in the positioning groove 21, and then starts the cylinder 312 through a control system, the piston rod of the cylinder 312 is extended, and then the sliding block 311 is pushed to be close to the sensor shell.
[0047] The detection guide needle 6 on the sliding block 311 first contacts the end of the copper sheet, and then in the process of the piston rod of the cylinder 312 continuing to extend, the detection guide needle 6 is pushed back into the sliding hole 4 by the copper sheet in the opposite direction, the pressing spring 8 is pressed by the top sheet 7 matched with the closed end of the sliding hole 4, until the piston rod of the cylinder 312 is completely extended.
[0048] At this time, the other end of the detection guide needle 6 relative to the copper sheet should be in contact with the corresponding wire 313, that is, the power supply, the wire 313, the copper sheet and the detection guide needle 6 form a closed circuit, and there is current passing through the circuit. If the copper sheet has a problem in conductivity, the above-mentioned circuit is in an open state, and the control system cannot detect that there is current passing through, at which time the alarm will issue an alarm.
[0049] Similarly, when the piston rod of the cylinder 312 is fully extended, the light hole 9 on the detection guide needle 6 should be able to allow the laser emitted by the laser emitter 321 to pass through and be received by the laser receiver 322. If there is a problem with the length of the copper sheet, the light hole 9 deviates from the accurate position, so that the laser emitted by the laser emitter 321 cannot be received by the laser receiver 322, and the alarm will also issue an alarm.
[0050] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
