Description

Technical Field

[0001] This utility model relates to the field of relay assembly technology, specifically to a riveting machine for an armature moving spring assembly. Background Technology

[0002] In the field of modern electronic control technology, relays, as a key electronic control device, are widely used in various automatic control circuit systems. In the traditional assembly process of relays, the assembly of the moving contact assembly mainly relies on manual labor. The specific operation steps are as follows: First, the moving contact is manually inserted into the contact riveting hole of the moving spring assembly. Then, the moving spring assembly and the conductive plate are placed on a riveting machine, one on top of the other, so that the contact riveting holes of the moving spring assembly and the conductive plate are aligned. Subsequently, the moving contact is riveted into the contact riveting holes of the moving spring assembly and the conductive plate in sequence by the riveting machine, thereby pressing and fixing the moving contact, the moving spring assembly, and the conductive plate into a whole, completing the assembly of the moving block assembly. Then, rivets are manually inserted into the rivet holes of the aforementioned moving spring assembly. The moving block assembly, insulating plate, and armature are then placed one on top of the other on a riveting machine, ensuring the rivet holes of these components are aligned. Finally, the riveting machine presses the rivets into the rivet holes of the moving spring assembly, insulating plate, and armature, thus pressing and fixing the rivets, moving block assembly, insulating plate, and armature together to complete the assembly of the moving contact assembly. This entire manual assembly process is not only time-consuming and labor-intensive, but also, due to the randomness and uncertainty of manual operation, it is difficult to guarantee the assembly accuracy and quality stability of each moving contact assembly.

[0003] Given the numerous drawbacks of the traditional manual assembly method, it is particularly necessary to develop a riveting machine that can automate and precisely complete the riveting of the armature moving spring assembly. Utility Model Content

[0041] (III) Beneficial Effects

[0042] Compared with the prior art, the riveting machine for armature moving spring assembly provided by this utility model has the following advantages:

[0043] When using the armature moving spring assembly riveting machine provided by this utility model, firstly, the conductive sheet feeding device transfers the conductive sheets one by one to the first fixtures on the first conveyor line; then, the first conveyor line conveys the first fixtures containing the conductive sheets to the moving spring feeding device, which transfers the moving spring assembly to the first fixture containing the conductive sheets, so that the contact riveting holes of the conductive sheets and the contact riveting holes of the moving spring assembly are aligned; then, the first conveyor line conveys the first fixture containing the conductive sheets and the moving spring assembly to the moving contact feeding device, which transfers the moving contacts and inserts them into the contact riveting holes of the moving spring assembly on the first fixture; subsequently, the first conveyor line conveys the first fixture to the first riveting device, which rivets the moving contacts into the contact riveting holes of the moving spring assembly and the conductive sheets, thereby pressing and fixing the moving contacts, the moving spring assembly, and the conductive sheets into one piece to form a moving block assembly; simultaneously with the assembly of the moving block assembly, the armature feeding device transfers the armatures one by one to the second... On each of the second fixtures of the conveyor line, the second conveyor line transports the second fixture containing the armature to the insulating plate loading device, which transfers the insulating plate to the second fixture containing the armature, aligning the rivet holes of the insulating plate and the armature. Subsequently, the first conveyor line transports the first fixture to the transfer device, and the second conveyor line transports the aforementioned second fixture to the transfer device, which transfers the moving block assembly from the first fixture to the second fixture, aligning the rivet holes of the moving spring assembly with the rivet holes of the insulating plate.

[0063] This utility model provides a riveting machine for an armature moving spring assembly, which solves the problems of how to automatically assemble the moving block assembly 2011 and the moving contact assembly 201.

[0064] See Figure 1 As shown, Figure 1 The image shown is a top view of the armature moving spring assembly riveting machine in the embodiment.

[0065] Both the first conveyor line 102 and the second conveyor line 103 are mounted on the frame 101.

[0066] The conductive sheet feeding device 104, the moving spring feeding device 105, the moving contact feeding device 106, the first riveting device 107, and the transfer device 108 are all mounted on the frame 101 and arranged sequentially along the conveying direction of the first conveying line 102.

[0067] The armature feeding device 109, the insulating plate feeding device 110, the rivet feeding device 111, and the second riveting device 112 are all installed on the frame 101, and the armature feeding device 109, the insulating plate feeding device 110, the transfer device 108, the rivet feeding device 111, and the second riveting device 112 are arranged sequentially along the conveying direction of the second conveying line 103.

[0068] The conductive sheet feeding device 104 is used to transfer the conductive sheet 2012 onto the first fixture 1021; the movable spring feeding device 105 is used to transfer the movable spring assembly 2013 onto the first fixture 1021 containing the conductive sheet 2012; the movable contact feeding device 106 is used to transfer the movable contact 2014 and insert it into the movable spring assembly 2013 on the first fixture 1021; the riveting device is used to press the movable contact 2014, the movable spring assembly 2013, and the conductive sheet 2012 into a single unit to form the movable block assembly 2011; and the armature feeding device 109 is used to transfer the armature 2015 onto the first fixture 1021. On the second fixture 1031, the insulating plate loading device 110 is used to transfer the insulating plate 2016 to the second fixture 1031 equipped with the armature 2015. The transfer device 108 is used to transfer the moving block assembly 2011 on the first fixture 1021 to the second fixture 1031 equipped with the insulating plate 2016. The rivet loading device 111 is used to transfer the rivet 2017 and insert it into the moving block assembly 2011 of the second fixture 1031. The second riveting device 112 is used to press the rivet 2017, the moving block assembly 2011, the insulating plate 2016 and the armature 2015 into a whole.

[0069] When using the armature moving spring assembly riveting machine of the above technical solution, firstly, the conductive sheet feeding device 104 transfers the conductive sheets 2012 one by one to the first fixtures 1021 of the first conveyor line 102; then, the first conveyor line 102 conveys the first fixtures 1021 containing the conductive sheets 2012 to the moving spring feeding device 105, and the moving spring feeding device 105 transfers the moving spring assembly 2013 to the first fixtures 1021 containing the conductive sheets 2012, so that the contact riveting holes 2018 of the conductive sheets 2012 and the contact riveting holes 2018 of the moving spring assembly 2013 are aligned; then, the first conveyor line 102 conveys the first fixture 1021 containing the conductive sheets 2012 and the moving spring assembly 2013 to the moving contact feeding device. At position 106, the moving contact feeding device 106 transfers the moving contact 2014 and inserts it into the contact riveting hole 2018 of the moving spring assembly 2013 of the first fixture 1021; subsequently, the first conveyor line 102 conveys the first fixture 1021 to the first riveting device 107, which rivets the moving contact 2014 into the contact riveting hole 2018 of the moving spring assembly 2013 and the conductive sheet 2012, thereby pressing and fixing the moving contact 2014, the moving spring assembly 2013, and the conductive sheet 2012 into one piece to form the moving block assembly 2011; while the moving block assembly 2011 is being assembled, the armature feeding device 109 transfers the armatures 2015 one by one to each of the second fixtures 1031 of the second conveyor line 103. First, the second conveyor line 103 conveys the second fixture 1031, which is equipped with the armature 2015, to the insulating plate loading device 110. The insulating plate loading device 110 transfers the insulating plate 2016 onto the second fixture 1031, so that the rivet holes 2019 of the insulating plate 2016 and the rivet holes 2019 of the armature 2015 are aligned. Then, the first conveyor line 102 conveys the first fixture 1021 to the transfer device 108, and the second conveyor line 103 conveys the second fixture 1031 to the transfer device 108. The transfer device 108 transfers the moving block assembly 2011 on the first fixture 1021 to the second fixture 1031, so that the rivet holes 2019 of the moving spring assembly 2013 are also aligned. The rivet holes 2019 of the insulating plate 2016 are positioned opposite each other; then, the second conveyor line 103 conveys the second fixture 1031 to the rivet feeding device 111, which transfers the rivet 2017 and inserts it into the rivet hole 2019 of the moving spring assembly 2013 of the second fixture 1031; finally, the second conveyor line 103 conveys the second fixture 1031 to the second riveting device 112, which rivets the rivet 2017 into the rivet holes 2019 of the moving spring assembly 2013, the insulating plate 2016, and the armature 2015, thereby pressing and fixing the rivet 2017, the moving block assembly 2011, the insulating plate 2016, and the armature 2015 into a whole to form the moving contact assembly 201.

[0070] As can be seen, the armature moving spring assembly riveting machine can automatically feed, assemble, and rivet the moving contact 2014, moving spring assembly 2013, and conductive sheet 2012 to form the moving block assembly 2011. It can also automatically feed, assemble, and rivet the rivet 2017, moving block assembly 2011, insulating plate 2016, and armature 2015 to form the moving contact assembly 201. This replaces manual assembly, thereby significantly improving the assembly efficiency and quality stability of relays, solving the efficiency and quality problems caused by manual assembly, reducing labor intensity, and promoting the relay industry towards intelligent and automated development.

[0071] Both the first riveting device 107 and the second riveting device 112 mentioned above can use existing riveting machines.

[0072] See Figure 1 As shown, based on the above embodiments, the conductive sheet feeding device 104, the moving spring feeding device 105, the moving contact feeding device 106, the armature feeding device 109, the insulating plate feeding device 110, and the rivet feeding device 111 all include a feeding mechanism 113, a distributing mechanism 114, and a transfer mechanism 115. The feeding mechanism 113 is mounted on the frame 101 and is used for continuously conveying workpieces. The distributing mechanism 114 is mounted at the discharge end of the feeding mechanism 113 and is used to receive workpieces from the feeding mechanism 113 and transfer them one by one to the transfer mechanism 115. The transfer mechanism 115 is mounted on the frame 101 and is used to transfer the workpieces from the distributing mechanism 114 to the corresponding first fixture 1021 or second fixture 1031. Thus, the armature moving spring assembly riveting machine, through the cooperation of the feeding mechanism 113, the distributing mechanism 114 and the transfer mechanism 115, can realize the feeding of each workpiece to the corresponding first fixture 1021 or second fixture 1031 one by one.

[0073] The aforementioned feeding mechanism 113 can be formed using an existing combination of vibratory feeder and linear vibrator.

[0074] The aforementioned transfer mechanism 115 can use an existing two-axis linear drive mechanism, a three-axis linear drive mechanism, or a robotic arm, with its output end equipped with an existing clamping cylinder or vacuum suction head. In this way, the transfer mechanism 115 can grasp the workpiece on the dispensing mechanism 114 by clamping or vacuum suction, and then transfer the workpiece to the corresponding first fixture 1021 or second fixture 1031.

[0075] See Figure 2 As shown, Figure 2This is a partial structural diagram of the conductive sheet feeding device. In a first embodiment of the dispensing mechanism 114, the dispensing mechanism 114 includes a movable block 1141, a movable block drive 1142, a stop block 1143, and a stop block drive 1144. The movable block 1141 is slidably connected to the frame 101 along the discharge direction of the feeding mechanism 113 and has a receiving groove 1145 for accommodating and limiting a single workpiece. The groove wall of the receiving groove 1145 has an opening 1146 for docking with the discharge end of the feeding mechanism 113. The movable block drive 1142 is mounted on the frame 101 by means of screwing or welding and is drive-connected to the movable block 1141. The movable block drive 1142 is used to drive the movable block 1141 to reciprocate between a first position and a second position. The stop block drive 1144 is mounted on the discharge end of the feeding mechanism 113 by means of screwing or welding and is drive-connected to the stop block 1143. The stop block drive 1144 is used to drive the stop block 1143 to move toward or away from the discharge end of the feeding mechanism 113. Specifically, in the first position, the opening 1146 of the movable block 1141 is aligned with the discharge end of the feeding mechanism 113; in the second position, the receiving groove 1145 is located below the transfer mechanism 115, and the stop block 1143 blocks the feeding mechanism 113 from outputting the workpiece. Thus, during feeding, firstly, the initial position of the movable block 1141 is the first position, and the feeding mechanism 113 inputs a single workpiece into the receiving groove 1145. Then, the stop block drive 1144 drives the stop block 1143 to move towards the discharge end of the feeding mechanism 113, and the stop block 1143 blocks the feeding mechanism 113 from outputting the workpiece. Next, the movable block drive 1142 drives the movable block 1141 to slide to the second position, and the transfer mechanism 115 transfers the workpiece in the receiving groove 1145 to the corresponding first fixture 1021 or second fixture 1031. Finally, the movable block drive 1142 drives the movable block 1141 back to the first position, and the stop block drive 1144 drives the stop block 1143 to move away from the discharge end of the feeding mechanism 113 so that the feeding mechanism 113 inputs the next workpiece into the receiving groove 1145. It can be seen that the material distribution mechanism 114, through the cooperation of the movable block 1141 and the movable block drive 1142, can separate and remove the workpieces one by one from the discharge end of the feeding mechanism 113 so that the transfer mechanism 115 can pick them up one by one. During the material distribution process, as the movable block 1141 slides to the second position along the discharge direction of the feeding mechanism 113, the discharge end of the feeding mechanism 113 will be exposed. Therefore, the material distribution mechanism 114, through the cooperation of the stop block 1143 and the stop block drive 1144, can play a blocking role, effectively blocking the feeding mechanism 113 from outputting workpieces, so as to prevent the workpieces from falling out.

[0076] In this embodiment, the material distribution mechanism 114 of the conductive sheet feeding device 104 adopts the first implementation method described above.

[0077] See Figure 3 As shown, Figure 3This is a partial structural diagram of the spring-loaded feeding device. In a second embodiment of the material distribution mechanism 114, the material distribution mechanism 114 includes a movable block 1141, a telescopic drive member 1147, a rotary drive member 1148, a stop block 1143, and a stop block drive member 1144. The movable block 1141 has a receiving groove 1145 for accommodating and limiting a single workpiece. The groove wall of the receiving groove 1145 has an opening 1146 for docking with the discharge end of the feeding mechanism 113. The telescopic drive member 1147 is mounted on the frame 101 by means of screwing or welding. The rotary drive member 1148 is mounted on the output end of the telescopic drive member 1147 by means of screwing or welding and is connected to the movable block 1141 in a transmission manner. The telescopic drive member 1147 is used to drive the rotary drive member 1148 and the movable block 1141 to slide along the discharge direction of the feeding mechanism 113. The rotary drive member 1148 is used to drive the movable block 1141 to rotate by a certain angle. The stop block drive 1144 is mounted on the discharge end of the feeding mechanism 113 by means of screwing or welding, and is connected to the stop block 1143 in a transmission manner. The stop block drive 1144 is used to drive the stop block 1143 to move toward or away from the discharge end of the feeding mechanism 113. The telescopic drive 1147 and the rotary drive 1148 together drive the movable block 1141 to reciprocate between a first position and a second position. In the first position, the opening 1146 of the movable block 1141 is aligned with the discharge end of the feeding mechanism 113; in the second position, the receiving groove 1145 is located below the transfer mechanism 115, and the stop block 1143 blocks the feeding mechanism 113 from outputting the workpiece. Thus, during feeding, firstly, the initial position of the movable block 1141 is the first position. The feeding mechanism 113 inputs a single workpiece into the receiving groove 1145. Then, the stop block drive 1144 drives the stop block 1143 to move towards the discharge end of the feeding mechanism 113, and the stop block 1143 blocks the feeding mechanism 113 from outputting the workpiece. Next, the telescopic drive 1147 drives the movable block 1141 to slide away from the discharge end of the feeding mechanism 113 along the discharge direction. The rotation drive 1148 drives the movable block 1141 to rotate a certain angle to the second position. The transfer mechanism 115 transfers the workpiece in the receiving groove 1145 to the corresponding first fixture 1021 or second fixture 1031; finally, the rotary drive 1148 drives the movable block 1141 to rotate in the opposite direction by the same angle, the telescopic drive 1147 drives the movable block 1141 to slide along the discharge direction of the feeding mechanism 113 toward the discharge end of the feeding mechanism 113, thereby returning to the first position, and the stop drive 1144 drives the stop block 1143 to move away from the discharge end of the feeding mechanism 113 so that the feeding mechanism 113 can input the next workpiece into the receiving groove 1145.As can be seen, in this embodiment, since the discharge direction of the feeding mechanism 113 is not parallel or perpendicular to the horizontal displacement direction of the transfer mechanism 115, the material separating mechanism 114 provided in this embodiment, through the cooperation of the movable block 1141, the telescopic drive member 1147 and the rotary drive member 1148, can not only separate and remove the workpieces one by one from the discharge end of the feeding mechanism 113, but also rotate a certain angle so that the transfer mechanism 115 can grab them. During the material separating process, since the telescopic drive member 1147 drives the movable block 1141 to slide along the discharge direction of the feeding mechanism 113, the discharge end of the feeding mechanism 113 will be exposed. Therefore, the material separating mechanism 114, through the cooperation of the stop block 1143 and the stop block drive member 1144, can play a blocking role, effectively blocking the feeding mechanism 113 from outputting workpieces, so as to prevent the workpieces from falling out.

[0078] In this embodiment, the material distribution mechanism 114 of the moving spring feeding device 105 adopts the second implementation method described above.

[0079] In both of the above embodiments, the stop block 1143 can block the feeding mechanism 113 from continuing to output workpieces by pressing down on the workpiece or by inserting it into the workpiece.

[0080] See Figure 4 , Figure 5 and Figure 6 As shown, Figure 4 This is a partial structural diagram of the moving contact feeding device. Figure 5 This is a partial structural diagram of the armature feeding device. Figure 6This is a partial structural diagram of the insulating board feeding device. In a third embodiment of the feeding mechanism 114, the feeding mechanism 114 includes a movable block 1141 and a movable block drive member 1142. The movable block 1141 is slidably connected to the discharge end of the feeding mechanism 113 in a horizontal direction perpendicular to the discharge direction of the feeding mechanism 113. The movable block 1141 has a receiving groove 1145 for accommodating and limiting a single workpiece, and the groove wall of the receiving groove 1145 has an opening 1146 for docking with the discharge end of the feeding mechanism 113. The movable block drive member 1142 is mounted on the frame 101 by means of screwing or welding, and is drively connected to the movable block 1141. The movable block drive member 1142 is used to drive the movable block 1141 to reciprocate between a first position and a second position. In the first position, the opening 1146 of the movable block 1141 is aligned with the discharge end of the feeding mechanism 113. In the second position, the receiving groove 1145 is located below the transfer mechanism 115, and the movable block 1141 blocks the discharge end of the feeding mechanism 113. Thus, the material distribution process of the material distribution mechanism 114 provided in this embodiment is the same as that in the first embodiment. However, since the movable block 1141 in this embodiment slides in a horizontal direction perpendicular to the discharge direction of the feeding mechanism 113, the discharge end of the feeding mechanism 113 can be blocked by the movable block 1141, thus playing a blocking role. No additional stop block 1143 and stop block drive member 1144 are required, effectively reducing the cost of the material distribution mechanism 114.

[0081] In this embodiment, the material distribution mechanism 114 of the moving contact feeding device 106, the armature feeding device 109, and the insulating plate feeding device 110 all adopt the third implementation method described above.

[0082] See Figure 7 As shown, Figure 7This is a partial structural diagram of the rivet feeding device. In the fourth embodiment of the material distribution mechanism 114, the material distribution mechanism 114 includes a movable block 1141 and a movable block drive member 1142. The movable block 1141 is slidably connected to the discharge end of the feeding mechanism 113 in a vertical direction perpendicular to the discharge direction of the feeding mechanism 113. The movable block 1141 has a receiving groove 1145 for accommodating and limiting a single workpiece, and the groove wall of the receiving groove 1145 has an opening 1146 for docking with the discharge end of the feeding mechanism 113. The movable block drive member 1142 is mounted on the frame 101 by means of screwing or welding, and is drively connected to the movable block 1141. The movable block drive member 1142 is used to drive the movable block 1141 to reciprocate between a first position and a second position. In the first position, the opening 1146 of the movable block 1141 is at the same height and connected to the discharge end of the feeding mechanism 113. In the second position, the receiving groove 1145 is higher than the discharge end of the feeding mechanism 113, and the movable block 1141 blocks the discharge end of the feeding mechanism 113. Thus, the material distribution mechanism 114 provided in this embodiment distributes materials by raising and lowering the movable block 1141. The material distribution process is similar to that in the third embodiment. Since the movable block 1141 in this embodiment slides in a vertical direction perpendicular to the discharge direction of the feeding mechanism 113, the discharge end of the feeding mechanism 113 can also be blocked by the movable block 1141, without the need for additional stop blocks 1143 and stop drive components 1144, effectively reducing the cost of the material distribution mechanism 114.

[0083] In this embodiment, the material distribution mechanism 114 of the rivet feeding device 111 adopts the fourth implementation method described above.

[0084] The aforementioned movable block drive 1142, stop block drive 1144, and telescopic drive 1147 can all use existing linear drive mechanisms such as telescopic cylinders or telescopic poles. The aforementioned rotary drive 1148 can use existing rotary drive mechanisms such as rotary cylinders or rotary motors.

[0085] See Figure 1 and Figure 5 As shown, based on any of the above embodiments, the armature feeding device 109 further includes a shaping mechanism 1091. The shaping mechanism 1091 is installed above the discharge end of the feeding mechanism 113 and is used to flatten the armature 2015. In this way, the shaping mechanism 1091 can perform a shaping function, improve the flatness of the armature 2015 output by the feeding mechanism 113, thereby improving the quality of the moving contact assembly 201.

[0086] The aforementioned shaping mechanism 1091 can use an existing flattening and shaping mechanism, and a material distribution or blocking mechanism can also be set downstream of the aforementioned shaping mechanism 1091 to prevent the armature 2015 from being directly output before it has been shaped.

[0087] See Figure 1 As shown, based on any of the above embodiments, the armature moving spring assembly riveting machine further includes two flipping devices 116 and a riveting detection device 117 mounted on the frame 101. The riveting detection device 117 and one of the flipping devices 116 are mounted between the moving spring feeding device 105 and the moving contact feeding device 106, while the other flipping device 116 is mounted downstream of the first riveting device 107. The riveting detection device 117 is used to detect whether the riveting surface of the moving spring assembly 2013 on the first fixture 1021 is facing upwards. The flipping device 116 is used to raise or lower the moving spring assembly 2013 on the first fixture 1021, and to flip the moving spring assembly 2013 180 degrees. Thus, after the moving spring assembly 2013 is loaded, the first conveyor line 102 transports the first fixture 1021, which contains the conductive sheet 2012 and the moving spring assembly 2013, to the flipping device 116 located upstream. The riveting detection device 117 detects whether the riveting surface of the moving spring assembly 2013 on the first fixture 1021 is facing upward. If so, the flipping device 116 does not operate, and the first conveyor line 102 transports the first fixture 1021 to the moving contact loading device 106. Otherwise, the flipping device 116 flips the moving spring assembly 2013 180 degrees so that the riveting surface of the moving spring assembly 2013 on the first fixture 1021 is facing upward, and then the first conveyor line 102 transports the first fixture 1021 to the moving contact loading device 106. After the moving contact 2014, the moving spring assembly 2013 and the conductive sheet 2012 are riveted into the moving block assembly 2011, the first conveyor line 102 conveys the first fixture 1021 containing the moving block assembly 2011 to the downstream flipping device 116. The flipping device 116 flips the moving block assembly 2011 on the first fixture 1021 by 180 degrees so that the subsequent transfer device 108 can transfer the moving block assembly 2011 to the second fixture 1031 for assembly.

[0088] The aforementioned flipping device 116 can be composed of existing lifting, rotating, and clamping mechanisms. These three mechanisms work together to grip the moving spring assembly 2013 on the first fixture 1021, flip the moving spring assembly 2013 180 degrees, and then place it back onto the first fixture 1021. The aforementioned riveting inspection device 117 can use existing visual inspection mechanisms such as CCD.

[0089] See Figure 1 and Figure 8 As shown, Figure 8The diagram shows a partial structure of the feeding device, defective product track, and good product track. Based on the above embodiment, the armature moving spring assembly riveting machine further includes a moving contact expansion degree detection device 118, two defective product tracks 119, a rivet expansion degree detection device 120, a feeding device 121, and a good product track 122. The moving contact expansion degree detection device 118 is installed upstream of the transfer device 108. The two defective product tracks 119 are respectively installed on one side of the first conveyor line 102 and the second conveyor line 103, and are used to convey unqualified moving block assemblies 2011 and unqualified moving contact assemblies 201, respectively. The transfer device 108 is used to screen qualified and unqualified moving block assemblies 2011 according to the detection results of the moving contact expansion degree detection device 118, transfer qualified moving block assemblies 2011 to the second fixture 1031 equipped with an insulating plate 2016, and transfer unqualified moving block assemblies 2011 to the corresponding defective product track 119. A rivet expansion detection device 120 is installed downstream of the second riveting device 112, and a good product track 122 is installed on one side of the unloading device 121 for conveying qualified moving contact components 201. The unloading device 121 is installed downstream of the rivet expansion detection device 120 and is used to screen qualified and unqualified moving contact components 201 according to the detection results of the rivet expansion detection device 120, and transfer qualified moving contact components 201 to the good product track 122, and transfer unqualified contact components to the corresponding defective product track 119. In this way, the present invention detects the expansion of moving contact 2014 and rivet 2017 after riveting by the moving contact expansion detection device 118 and the rivet expansion detection device 120, respectively, and can determine the riveting status of moving block component 2011 and moving contact component 201, so that the transfer device 108 and the unloading device 121 can classify and convey qualified and unqualified products, thereby facilitating subsequent different processing.

[0090] Both the aforementioned moving contact expansion detection device 118 and rivet expansion detection device 120 can use existing visual inspection mechanisms such as CCD.

[0091] See Figure 1As shown, in one embodiment of the first conveyor line 102 and the second conveyor line 103, both the first conveyor line 102 and the second conveyor line 103 are dividers. At least five first fixtures 1021 are arranged in a ring at intervals on the first conveyor line 102, and at least five second fixtures 1031 are arranged in a ring at intervals on the second conveyor line 103. A conductive sheet feeding device 104, a moving spring feeding device 105, a moving contact feeding device 106, a first riveting device 107, and a transfer device 108 are sequentially arranged outside the first conveyor line 102, and each of these devices is positioned opposite to one of the first fixtures 1021. The armature feeding device 109, the insulating plate feeding device 110, the transfer device 108, the rivet feeding device 111, and the second riveting device 112 are sequentially arranged on the outside of the second conveyor line 103, and the armature feeding device 109, the insulating plate feeding device 110, the transfer device 108, the rivet feeding device 111, and the second riveting device 112 are all arranged opposite to one of the second fixtures 1031.

[0092] In addition to the above-described embodiments, the first conveyor line 102 and the second conveyor line 103 can also use any one of the existing pusher mechanism, conveyor belt, shift fork mechanism, etc., to provide driving force, or a combination of multiple of them to provide driving force, so as to realize the function of conveying the first fixture 1021 and the second fixture 1031.

[0093] See Figure 6 , Figure 7 and Figure 8As shown, in one embodiment of the second fixture 1031, the second fixture 1031 includes a limiting seat 1032, a limiting rod 1033, a pressure rod 1034, and a pressure rod drive member 1035. The limiting seat 1032 has a limiting groove 1036. The limiting groove 1036 is adapted to the shape and size of the moving contact assembly 201 and is used to place and limit the armature 2015, the insulating plate 2016, and / or the moving block assembly 2011. The limiting rod 1033 is rotatably connected to the limiting seat 1032. A torsion spring (not shown in the figure) is installed at the rotatable connection between the limiting rod 1033 and the limiting seat 1032. The torsion spring is used to drive one end of the limiting rod 1033 to swing toward the limiting groove 1036, so as to press the armature 2015, the insulating plate 2016, and / or the moving block assembly 2011 tightly within the limiting groove 1036. The pressure rod 1034 is located above the other end of the limiting rod 1033. The pressure rod drive 1035 is connected to the pressure rod 1034 and is used to drive the pressure rod 1034 to move towards or away from the limiting rod 1033. In this way, the second fixture 1031 drives one end of the limiting rod 1033 to swing towards the limiting groove 1036 through the torsion spring, which can play a role in positioning the workpiece on the second fixture 1031 to prevent the workpiece from moving during the assembly process and affecting the assembly accuracy; while the pressure rod 1034 descends and abuts against the other end of the limiting rod 1033, which can drive the limiting rod 1033 to overcome the elastic swing of the torsion spring, thereby opening the limiting groove 1036 to remove or put in the workpiece. This opening operation is simple and easy to implement.
