The contact bridge 51 is made of copper, the spring 52 is made of spring steel, and the contact bridge seat 53 is made of ABS plastic (Acrylonitrile Butadiene Styrene).
As shown in fig. 2, fig. 2 is a schematic diagram of a press-fitting process when the contact bridge assembly contains a spring, and in an initial state, the contact bridge 51 in the contact bridge assembly 5 is far away from the bottom of the contact bridge seat 53; in the press-fitting stage, namely when the contact bridge assembly 5 is pressed, the contact bridge 51 is pressed down by external force, the contact bridge 51 is buckled with the contact bridge seat 53, and when the contact bridge 51 is continuously pressed, the top of the contact bridge 51 is flush with the top of the contact bridge seat 53; in the free state, i.e. after releasing the external force, the contact bridge assembly 5 is in the free state after press-fitting, and at this time, the contact bridge 51 is sprung by the force of the spring 52, so that the top of the contact bridge 51 is higher than the top of the contact bridge seat 53, but since the contact bridge 51 is buckled with the contact bridge seat 53 after press-fitting, the contact bridge 51 is not separated from the contact bridge seat 53, i.e. the height of the contact bridge 51 is lower than the height of the initial state when in the free state.
As shown in fig. 3, fig. 3 is a schematic diagram of a press-fitting process when the contact bridge assembly is neglected to install springs, and in an initial state, the contact bridge 51 is influenced by the buckling part and is far away from the bottom of the contact bridge seat 53; in the press-fitting stage, namely when the contact bridge assembly 5 is press-fitted, the contact bridge 51 is pressed down by external force, the contact bridge 51 is buckled with the contact bridge seat 53, and the contact bridge 51 is directly contacted with the bottom of the contact bridge seat 53 due to no counterforce of the spring 52; in a free state, that is, after the external force is released, since the spring 52 is not provided in the contact bridge assembly 5, the contact bridge 51 is not subjected to the force of the spring 52, and thus the position of the contact bridge 51 is not changed. When the spring 52 is not installed in the contact bridge assembly 5, the switch corresponding to the automobile part is abnormal, and a safety hazard is caused.
As shown in fig. 4, as an embodiment of the present invention, a detection device for a contact bridge assembly is disclosed, which comprises an upper die 2, a lower die 3 and a support shaft 4, wherein the upper die 2 and the lower die 3 are connected by the support shaft 4; the upper die 2 comprises a cylinder fixing plate 21, a first cylinder 22, a mounting plate 23, an insulating fixing plate 24, two probes 25 and a test structure 26; the cylinder fixing plate 21 is fixed on the supporting shaft 4; the first cylinder 22 is fixed on the cylinder fixing plate 21, and the first cylinder 22 comprises a first piston 221; the mounting plate 23 is connected to the support shaft 4 and the first piston 221, and the mounting plate 23 is slidable in the axial direction of the support shaft 4 by the up-and-down movement of the first piston 221; the insulating fixing plate 24 is made of an insulating material and is fixed on the mounting plate 23; the two probes 25 are made of conductive materials and are fixed on the insulating fixing plate 24, a gap is formed between the two probes 25, and the width of the gap is smaller than that of the contact bridge assembly 5; the test structure 26, the test structure 26 is respectively connected to the two probes 25, and tests a loop formed by the two probes 25; the lower die 3 comprises a bottom plate 31, a second cylinder 32 and a positioning plate 35, and the bottom plate 31 is fixed on the supporting shaft 4; the second cylinder 32 is fixed on the bottom plate 31 and comprises a second piston 321; the positioning plate 35 is fixed on the second piston 321, and a receiving groove 351 is formed in the positioning plate 35 to receive the contact bridge assembly 5, wherein the receiving groove 351 corresponds to the probe 25.

The probe 25 is made of metal and can be made of copper, and the copper has good conductive effect and is corrosion-resistant; as for the probe 25 connected to the insulating fixing plate 24 and not in contact with other structures, it is possible to prevent electric leakage and improve the safety of the detecting device 1, and of course, an insulating layer may be provided on the surface of the probe 25 to further improve the safety effect. The connection method of the probe 25 and the insulating fixing plate 24 may be engagement or welding, and is not limited herein.
Since the detecting device 1 comprises an upper cylinder and a lower cylinder, namely the first cylinder 22 and the second cylinder 32, the up-and-down displacement of the mounting plate 23, the insulating fixing plate 24, the probe 25 and the positioning plate 35 can be controlled through the corresponding first piston 221 and the second piston 321; placing the contact bridge assembly 5 into the positioning plate 35, when the first piston 221 of the first cylinder 22 controls the probe 25 to press the contact bridge assembly 5, so that the contact bridge assembly 5 is in a compressed state, if the contact bridge assembly 5 contains the spring 52, when the first cylinder 22 and the second cylinder 32 move in a backward direction, the probe 25 still contacts with the contact bridge assembly 5, and at this time, the test structure 26 can detect that the probe 25 is conducted with the contact bridge assembly 5, that is, the contact bridge assembly 5 contains the spring 52, so as to meet the requirement; if the spring 52 is not present in the contact bridge assembly 5, the probe 25 will not contact the contact bridge assembly 5 when the first cylinder 22 and the second cylinder 32 move back to back, and the test structure 26 can detect that the probe 25 is not in communication with the contact bridge assembly 5, indicating that the spring 52 is not present in the contact bridge assembly 5. The detection device 1 can detect whether the spring 52 in the contact bridge assembly 5 is neglected to be installed in percentage, so that the problems of unreliable detection, time consumption and labor consumption in the existing method are solved; in addition, the detection device 1 of the present application can also serve as a press-fitting device for the contact bridge assembly 5, and after a plurality of components of the contact bridge assembly 5 are correspondingly placed in the accommodating groove 351 of the positioning plate 35, the probe 25 can extrude the contact bridge assembly 5, thereby completing the press-fitting process; therefore, the contact bridge assembly 5 detection device 1 in the application is a structure integrating press mounting and detection of the contact bridge 51, greatly improves production automation, reduces manual operation and improves productivity.
In an embodiment, the lower die 3 further includes at least two reference support blocks 33 and at least two guide shafts 34, the reference support blocks 33 are fixed on the bottom plate 31 and located at two ends of the second cylinder 32; the guide shafts 34 are connected to the reference support blocks 33 in a one-to-one correspondence manner, and penetrate through the positioning plate 35. Specifically, the reference support block 33 is connected to the bottom plate 31 by a screw, and the reference support block 33 is connected to the guide shaft 34 by a through-hole shaft. Through setting up benchmark supporting shoe 33 and guiding axle 34, and the guiding axle 34 that is located the locating plate 35 both ends runs through locating plate 35 for second cylinder 32 both ends are stable, can not incline, just can be more accurate when carrying out the pressure equipment and examining contact bridge assembly 5 like this.
In an embodiment, the upper die 2 further includes two limit blocks 27, the two limit blocks 27 are respectively a first limit block 271 and a second limit block 275, and the first limit block 271 and the second limit block 275 are both connected to the mounting plate 23 and are respectively located at two ends of the insulating fixing plate 24; the first limiting block 271 comprises a first opening 272, the second limiting block 275 comprises a second opening 276, the first opening 272 and the second opening 276 are oppositely arranged, and the distance between the side wall of the first opening 272 and the side wall of the second opening 276 is greater than the width of the positioning plate 35; the height of the sidewall of the first opening 272 and the height of the sidewall of the second opening 276 are greater than the height of the positioning plate 35. Specifically, the first limit block 271 is connected with the mounting plate 23 through screws, and the second limit block 275 is connected with the mounting plate 23 through screws. When the first piston 221 moves to a certain extent, the stopper lower reference surface 274 will contact with the upper surface of the reference support block 33, so as to prevent the first piston 221 from moving too far, and the contact bridge 51 and the contact bridge seat 53 in the contact bridge assembly 5 from being damaged due to excessive extrusion; when the second piston 321 moves to a certain degree, the positioning plate upper reference surface 352 contacts with the stopper upper reference surface 273, so that the second piston 321 is prevented from moving too far, and the contact bridge 51 and the contact bridge seat 53 in the contact bridge assembly 5 are excessively pressed and damaged; in addition, the height of the sidewall of the first opening 272 and the height of the sidewall of the second opening 276 are greater than the height of the positioning plate 35, so that the positioning plate 35 can move to press-fit the contact bridge assembly 5 when the stopper lower reference surface 274 contacts the upper surface of the reference support block 33.
In one embodiment, the height of the stop block 27 is greater than the sum of the height of the sidewall of the first opening 272 and the height of the probe 25; the height of the second stopper 275 is greater than the sum of the height of the sidewall of the second opening 276 and the height of the probe 25. Since the positioning plate 35 is provided with the accommodating groove 351 for accommodating the contact bridge assembly 5, when the reference surface 352 of the positioning plate contacts with the bottom of the probe 25, the contact bridge assembly 5 is in a pressing state; because the height of the limiting block 27 is greater than the sum of the height of the side wall of the first opening 272/the second opening 276 and the height of the probe 25, when the datum plane 352 on the positioning plate contacts with the bottom of the probe 25, a gap is formed between the probe 25 and the positioning plate 35, and the probe 25 can be prevented from continuously pressing the contact bridge assembly 5 to damage the contact bridge assembly 5; if the height of the stop block 27 is less than or equal to the sum of the height of the sidewall of the first/ second openings 272, 276 and the height of the probe 25, the contact bridge assembly 5 will directly bear the force of the first and second cylinders 22, 32, and the contact bridge assembly 5 may be damaged due to the excessive force.
In one embodiment, the kinetic energy of the first cylinder 22 is less than the kinetic energy of the second cylinder 32. The first cylinder 22 is a small cylinder, the extension force or kinetic energy of the piston is small, the second cylinder 32 is a large cylinder, the extension force or kinetic energy of the piston is large, firstly, the extension direction of the first piston 221 is downward, so that the kinetic energy required for extension is small, and the extension direction of the second piston 321 is upward, so that the gravity of the positioning plate 35 needs to be borne, and the required kinetic energy is large; in addition, when the first piston 221 and the second piston 321 extend out simultaneously to press the contact bridge assembly 5, the second piston 321 bears the pressing force of the first piston 221 and the gravity of the positioning plate 35, the mounting plate 23, the insulating fixing plate 24, the limiting block 27, the probe 25 and the contact assembly, and large power is required; if the kinetic energy of the first cylinder 22 is greater than the kinetic energy of the second cylinder 32, when the first piston 221 and the second piston 321 extend simultaneously to press the contact bridge assembly 5, the second piston 321 is directly compressed, which is likely to cause mechanical damage, and the press-fitting effect of the contact bridge assembly 5 is poor.
In addition, the detection device 1 has an axisymmetric structure. In this way, the first piston 221, the second piston 321 and the accommodating groove 351 are all located on the central axis of the detecting device 1, and when the first piston 221 and the second piston 321 extrude the contact bridge assembly 5 in the accommodating groove 351, the stress is more concentrated and does not shift, so as to avoid the situation of poor inspection result; in addition, the probe 25 and the limiting block 27 are also in an axisymmetric structure, so that the two ends of the positioning plate 35 and the mounting plate 23 are stressed equally and cannot deviate, and the stress of the contact bridge 51 is not uniform.
As shown in fig. 5, the test structure 26 includes a first lead 261, a second lead 262, a power source 263, a controller 264, an indicator light 265 and a buzzer 266, the first lead 261, the probe 25, the power source 263, the second lead 262 and the controller 264 are connected in series, the controller 264 detects whether the first lead 261 and the second lead 262 form a loop and controls the indicator light 265 and the buzzer 266; when two probes 25 contact with the contact bridge assembly 5, the first lead 261, the second lead 262, the probes 25 and the contact bridge assembly 5 form a conductive loop, and the controller 264 controls the indicator light 265 to emit light; when the probe 25 is not in contact with the contact bridge assembly 5, the first lead 261, the second lead 262 and the probe 25 cannot form a conductive loop, and the controller 264 controls the buzzer 266 to sound. Specifically, the Controller 264 is a PLC (Programmable Logic Controller). Whether the probe 25 is connected with the contact bridge assembly 5 can be judged by detecting the conduction condition of the circuit, and when the contact bridge assembly 5 contains the spring 52, the contact bridge assembly 5 is extruded and then restored to be in contact with the probe 25; when the contact bridge assembly 5 is not provided with the spring 52, the contact bridge assembly 5 cannot be restored after being pressed and cannot be in contact with the probe 25. In order to facilitate understanding of whether the spring 52 in the contact bridge assembly 5 is neglected, the test structure 26 is arranged, so that the connection condition of the probe 25 and the contact bridge assembly 5 does not need to be observed one by one, when an indicator lamp 265 of the test structure 26 emits light, the connection between the probe 25 and the contact bridge assembly 5 can be known, and the spring 52 in the contact bridge assembly 5 can also be known; when the buzzer 266 of the test structure 26 sounds, it is known that the probe 25 is not in contact with the contact bridge assembly 5, and it is also known that the spring 52 is not installed in the contact bridge assembly 5. The missing spring 52 in the contact bridge assembly 5 can be known in time through the test structure 26, and thus can be adjusted in time.
