Description

Technical Field

[0001] This application relates to the technical field of relay manufacturing, and in particular to a relay coil testing mechanism. Background Technology

[0002] The relay coil 8 is the core electromagnetic component of the relay. Essentially, it is an inductor coil that generates a magnetic field through changes in current, thereby controlling the relay contacts to open or close the circuit. A relay coil 8 is described below. Figure 1 It includes a coil body, a fastener 82 disposed on one side of the coil body, an armature 81 mounted on the coil body via the fastener 82, and iron plates 83 fixedly disposed on both sides of the coil body. The armature 81 is L-shaped in general, including a connecting part and a contact part. The connecting part and the contact part are integrally formed and connected together to form an L-shaped armature 81. A through-hole 84 is provided at the connection between the connecting part and the contact part. When the armature 81 is mounted on the coil body, its connecting part is attached to the side of the coil body where the fastener 82 is disposed, and the contact part is attached to the top of the coil body (i.e., the contact part of the coil body). The fastener 82 passes through the through-hole 84 through the armature 81 and fastens the armature 81 so that the armature 81 is mounted on the coil body.

[0003] In existing technology, when installing the armature, the clip needs to be squeezed so that the width of the clip's locking part is smaller than the through opening. This allows the armature to be installed on the coil body. After installation, the clip returns to its original width to hold the armature in place due to its elasticity. However, due to the squeezing force, the clip may not be able to return to its original width, resulting in the armature not being stably installed on the coil body. But due to gravity, even if the clip does not hold the armature in place, the armature will still appear to be attached to the coil body. This makes it difficult for operators to detect faulty relay coils in a timely manner. Therefore, this application proposes a relay coil detection mechanism. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a relay coil testing mechanism for detecting whether the clips on the coil body accurately engage the armature, so that staff can promptly identify faulty relay coils.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a relay coil detection mechanism, including a driving device, a mounting rod, a placement assembly, a limiting assembly, and a vision lens. One end of the mounting rod is mounted on the rotating end of the driving device. The placement assembly includes a placement base plate, a limiting vertical plate, a limiting top plate, and two pressing blocks. The limiting vertical plate is vertically fixedly connected to one end of the placement base plate. The limiting top plate is fixedly connected to the end of the limiting vertical plate away from the placement base plate and is opposite to the placement base plate. Both pressing blocks are inserted through the limiting top plate and one end extends between the limiting top plate and the placement base plate. The limiting vertical plate is fixedly connected to the mounting rod.

[0006] The placement component has an upright state and an inverted state. In the upright state, the placement component is located on one side of the driving device. The limiting component is used to place the relay coil and is placed on the placement base plate. At this time, both the placement component and the relay coil are upright. The top pressing block is used to press the limiting component to prevent the limiting component from shifting.

[0007] In the inverted state, the placement component is located on the other side of the drive device, and both the placement component and the relay coil are inverted; the drive device drives the placement component to rotate via the mounting rod to switch between the upright and inverted states.

[0008] The vision lens is located beside the inverted placement assembly and is used for visual monitoring to ensure that the armature on the inverted relay coil is installed accurately.

[0009] By adopting the above technical solution, after the relay coil is produced in the preceding process, the limiting component containing the relay coil is transported by the transport device towards the placement component. When the transport device transports the limiting component to the placement base plate, the top pressing block presses down on the top surface of the limiting component to prevent the limiting component from shifting inside the placement component. Subsequently, the drive device is activated, and the rotating end of the drive device rotates, causing the placement component to flip and move to one side of the vision lens, turning the placement component into an inverted state. At this time, due to the setting of the limiting component and the placement component, the relay coil will flip and invert as the placement component is inverted. If the latching piece does not accurately latch the armature, it will adhere to the armature on the coil body due to gravity. If the armature is not properly engaged, the latch will move downwards away from the coil body, creating a gap between the coil body and the armature. If the visual lens detects this gap, it indicates that the latch is not properly engaged with the armature, prompting a warning to the operator. This allows the operator to promptly identify the faulty relay coil. Conversely, if the latch is properly engaged with the armature, the armature will not move downwards due to gravity, and the visual lens will detect no gap between the coil body and the armature. In this case, no warning is needed, and the relay coil continues to rotate. This process effectively detects whether the latch on the coil body is properly engaged with the armature, enabling the operator to promptly identify faulty relay coils.

[0010] Furthermore, the limiting component includes a limiting base plate and multiple limiting blocks. When the placement component is in the upright position, the limiting base plate is placed on the placement base plate of the placement component. The multiple limiting blocks are fixedly arranged at intervals on the limiting base plate. A vertical limiting notch is opened on the opposite side of any two adjacent limiting blocks among the multiple limiting blocks.

[0011] By adopting the above technical solution, when the relay coil needs to be placed on the limiting component, it is only necessary to place the relay coil between multiple limiting blocks and extend both sides of the relay coil into the limiting notch so that the limiting block can lock the relay coil, thereby achieving the purpose of limiting the position of the relay.

[0012] Furthermore, the side of the limiting top plate facing away from the placement bottom plate is provided with a pressing component for pressing the top pressing block.

[0013] Furthermore, the compression assembly has two components, each corresponding to one of the two top pressing blocks. The compression assembly includes a connecting rod, an abutment block, and a compression spring. The connecting rod is vertically fixed on the side of the limiting top plate away from the placement bottom plate and located on the side of the corresponding top pressing block. The abutment block is fixed on the top of the connecting rod with its bottom surface facing the top surface of the top pressing block. The compression spring is located between the abutment block and the top pressing block. One end of the compression spring is fixedly connected to the abutment block, and the other end of the compression spring is used to push the top pressing block to compress the limiting assembly. The top pressing block is slidably inserted into the limiting top plate.

[0014] By adopting the above technical solution, although the top pressure block in the placement component can restrict the limiting component, in actual use, the limiting component needs to frequently pass through the placement component. Among them, the top pressure block contacts the limiting component most frequently. This leads to severe wear at the end of the top pressure block after the placement component has been used for a period of time, and it no longer has the effect of pressing the limiting component. The setting of the compression component solves this technical problem. With the setting of the compression component, when the limiting component moves into the placement component with the relay coil, the limiting block in the limiting component will squeeze the top pressure block, causing the top pressure block to move upward and compress the compression spring. At the same time, the compressed compression spring will also apply a pushing force to the top pressure block, so that the top pressure block presses the limiting block to fix the limiting component. When the end of the top pressure block wears after the placement component has been used for a period of time, the compression spring can still push the top pressure block to press the limiting block, so that the worn top pressure block can continue to exert the limiting effect on the limiting component, thereby improving the service life of the top pressure block.

[0015] Furthermore, the limiting top plate is provided with decompression components on both sides for the limiting top pressure block to compress the limiting component.

[0016] Furthermore, the decompression assembly includes two portal frames, two decompression blocks, two contact rods, two decompression rods, two connecting rods, and two connecting shafts. The two portal frames are located on both sides of the upright placement assembly. The two decompression blocks are fixedly connected to both sides of the limiting top plate. The two contact rods are connected to the two decompression rods one-to-one to form two sets of decompression components. The two sets of decompression components are located on opposite sides of the two decompression blocks. The two connecting shafts pass through the two sets of decompression components and the corresponding decompression blocks, so that the decompression components are rotatably connected to the decompression blocks. The two connecting rods are rotatably passed through the ends of the two decompression rods away from the contact rods, and one end is fixedly connected to the top pressure block. The decompression component has a restricted state and a released state. When the decompression component is in the restricted state, the decompression rod pushes the connecting rod upward, so that the top pressure block moves upward and compresses the compression spring. At this time, the contact rod abuts against one side of the top of the portal frame.

[0017] When the decompression component is in the released state, the contact rod separates from the gantry frame, and the pressure spring releases its elastic force, causing the decompression rod to move down with the top pressure block.

[0018] While the compression component improves the lifespan of the top pressure block, the relay coil still needs to be transported via a conveyor in actual use. When transporting the limiting component with the relay coil to the placement component, the compression component increases the friction between them, requiring the conveyor to output greater power to move the limiting component with the relay coil through the placement component. The decompression component solves this problem. When installing the entire testing mechanism, two portal frames need to be installed at an interval opposite to each other on the conveyor. When the device and the placement component are in the upright position, the two gantry frames need to be located on both sides of the placement component. This allows the transport device to transport the limit component with the relay coil into the placement component. When the placement component is in the upright position, the decompression component contacts the gantry frame and is in a restricted state. The decompression rod in the decompression component pushes the connecting rod upward, so that the top pressure block moves upward and compresses the compression spring. At this time, the compression spring cannot push the top pressure block to move, so the top pressure block will not apply pressure to the limit component. This allows the transport device to transport the limit component with the relay coil through the placement component without outputting more power, saving the energy consumption of the transport device.

[0019] On the other hand, since the top pressure block does not apply pressure to the limiting component, when the drive device rotates and flips the placement component via the mounting rod, the limiting component inside the placement component loses the restriction position of the top pressure block and moves downward, causing the relay coil on the limiting component to come into contact with the limiting top plate in the placement component. At this time, the vision lens cannot accurately detect whether the armature on the relay coil is accurately installed. The setting of the decompression component also solves this technical problem. When the drive device rotates and flips the placement component via the mounting rod, the decompression component is released from the gantry frame. The decompression component, which is no longer restricted by the gantry frame, becomes a freed state. At this time, the pressure spring releases its elastic force, causing the decompression rod to move downward with the top pressure block, so that the top pressure block presses against the limiting component to prevent the limiting component from shifting. This allows the vision lens to accurately detect whether the armature on the relay coil is accurately installed.

[0020] Furthermore, a support device is provided at the lower end of the vision lens, the support device being used to support the vision lens.

[0021] Furthermore, the support device includes a support base, a support rod, a mounting block, a mounting seat, and a refractive prism. The support rod is vertically fixedly mounted on the support base, the mounting block is fixedly mounted on the top of the support rod, the vision lens is vertically mounted on the mounting block with the lens facing downwards, the mounting seat is located directly below the vision lens and is fixedly mounted on the support rod, and the refractive prism is mounted on the mounting seat and is used to refract the inverted relay coil image for monitoring by the vision lens.

[0022] By adopting the above technical solution, when the vision lens monitors the inverted relay coil, the entire vision lens needs to be placed horizontally so that the vision lens can monitor the inverted relay coil. However, the horizontally placed vision lens occupies a large horizontal space, which is inconvenient for the installation of the vision lens. The setting of the support device solves this technical problem. By setting the support device, the vision lens can be installed vertically, reducing the horizontal space occupied by the vision lens. At the same time, the image of the inverted relay coil can be monitored through the refraction of the refracting prism, saving the installation space of the vision lens without affecting the monitoring of the vision lens.

[0023] Furthermore, a backlight plate with a relative refractive prism is provided on one side of the driving device.

[0024] The above technical solution is used to prevent the complex environment of the factory from affecting the refractive effect of the refracting prism.

[0025] Furthermore, a protective cover surrounding the vision lens is fixedly installed on the mounting block, and the protective cover has openings on the upper and lower sides for the vision lens to monitor.

[0026] The above technical solution is used to prevent the complex environment of the factory from affecting the monitoring effect of the vision lens.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through the configuration of the drive device, mounting rod, placement assembly, limiting assembly, and vision lens, the relay coil only needs to move into the placement assembly and be restricted by the limiting assembly. Then, the drive device, via the mounting rod, drives the placement assembly to flip and move it to one side of the vision lens, causing the placement assembly to become inverted. At this point, due to the setting of the limiting assembly and the placement assembly, the relay coil will flip and invert along with the inverted placement assembly. If the latching piece does not accurately engage the armature, due to gravity, the armature attached to the coil body will move downwards away from the coil body, creating a gap between the coil body and the armature, which will then be visible to the vision lens. If the lens detects a gap between the coil body and the armature, it indicates that the latch is not properly engaged with the armature, and a warning is issued to the operator so that the faulty relay coil can be detected in time. If the latch is properly engaged with the armature, the armature will not move downwards due to gravity because of the latch's restraint. In this case, the vision lens detects no gap between the coil body and the armature, indicating that the latch is properly engaged with the armature. Therefore, there is no need to warn the operator, and the relay coil can continue to rotate. This achieves the purpose of detecting whether the latch on the coil body is properly engaged with the armature, so that the operator can detect the faulty relay coil in time.

[0029] 2. By setting the pressure component, when the limit component moves into the placement component with the relay coil, the limit block in the limit component will squeeze the top pressure block, causing the top pressure block to move upward and compress the pressure spring. At the same time, the compressed pressure spring will also apply a pushing force to the top pressure block, so that the top pressure block presses against the limit block to fix the limit component. When the end of the top pressure block wears after the placement component has been used for a period of time, the pressure spring can still push the top pressure block to press against the limit block, so that the worn top pressure block can continue to exert a limiting effect on the limit component, thereby improving the service life of the top pressure block.

[0030] 3. By configuring the decompression component, when the placement component is in its upright position, the decompression component is in a restricted state in contact with the gantry frame. The decompression rod in the decompression rod pushes the connecting rod upward, causing the top pressure block to move upward and compress the compression spring. At this time, the compression spring cannot push the top pressure block to move, so the top pressure block will not apply pressure to the limiting component. This allows the transport device to transport the limiting component with the relay coil through the placement component without outputting more power, saving energy consumption of the transport device. On the other hand, since the top pressure block does not apply pressure to the limiting component, when the drive device drives the placement component to rotate and flip via the mounting rod, the limiting component inside the placement component loses its function. The limiting position of the top pressure block will move downward, causing the relay coil on the limiting component to come into contact with the limiting top plate in the placement component. At this time, the vision lens cannot accurately detect whether the armature on the relay coil is accurately installed. The setting of the decompression component also solves this technical problem. When the drive device drives the placement component to rotate and flip through the mounting rod, the decompression component is separated from the gantry frame. The decompression component, which is no longer restricted by the gantry frame, becomes a freed state. At this time, the pressure spring releases its elastic force, causing the decompression rod to move downward with the top pressure block, so that the top pressure block presses against the limiting component to prevent the limiting component from shifting. This allows the vision lens to accurately detect whether the armature on the relay coil is accurately installed. Attached Figure Description

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] Reference Figures 2 to 4 A relay coil testing mechanism includes a driving device 1, a mounting rod 10, a placement assembly 2, a limiting assembly 3, and a vision lens 4. One end of the mounting rod 10 is mounted on the rotating end of the driving device 1. The placement assembly 2 is mounted on the end of the mounting rod 10 away from the driving device 1. The placement assembly 2 includes a placement base plate 20, a limiting vertical plate 21, a limiting top plate 22, and two pressing blocks 23. The limiting vertical plate 21 is vertically fixed to one end of the placement base plate 20, and the limiting top plate 22 is fixedly connected to the end of the limiting vertical plate 21 away from the placement base plate 20 and is perpendicular to the placement base plate 20. Relatively speaking, both top pressing blocks 23 are inserted through the limiting top plate 22 and one end extends between the limiting top plate 22 and the placement base plate 20. There is a gap between the two top pressing blocks 23. The limiting vertical plate 21 is fixedly connected to the mounting rod 10. The limiting component 3 is used to place the relay coil 8 on the placement base plate 20. The top pressing blocks 23 are used to press the limiting component 3 to prevent the limiting component 3 from shifting. When the placement component 2 is in the upright position, the vision lens 4 is located on the side of the driving device 1 away from the placement component 2. The vision lens 4 is used to visually monitor whether the armature 81 on the relay coil 8 is accurately installed.

[0039] The vision lens 4 is existing technology and will not be described in detail here. Regarding the placement component, it has an upright state and an inverted state. In the upright state, the placement component 2 is located on one side of the drive device 1, and both the placement component 2 and the relay coil 8 are upright. In the inverted state, the placement component 2 is located on the other side of the drive device 1, and both the placement component 2 and the relay coil 8 are inverted. The vision lens 4 is located beside the inverted placement component 2 and is used to detect the inverted relay coil 8. It is used here to receive the transported limiting component 3 with the relay coil 8. Regarding the drive device 1, it can be a drive motor or a combination of a drive motor and other transmission structures. Specific transmission structures can be chain drive structures or synchronous belt drive structures. Regarding the mounting rod 10, it can be installed on the rotating end of the drive device 1 by welding, snap-fitting, or other fixing methods. The drive device 1 is mainly used to switch the placement component between the upright and inverted states via the mounting rod. Regarding the limiting component 3, refer to... Figure 5 It includes a limiting base plate 30 and multiple limiting blocks 31. The multiple limiting blocks 31 are fixedly arranged at intervals on the limiting base plate 30. Any two adjacent limiting blocks 31 have a vertical limiting notch 32 on their opposite sides. When the placement component 2 is in the upright position, the limiting base plate 30 is placed on the placement base plate 20 of the placement component 2.

[0040] Specifically, the number of limiting blocks 31 can be set according to the shape of the relay coil 8. For example, if the relay coil 8 is square in shape, only two limiting blocks 31 with a gap between them are needed. The pressing block 23 also restricts the limiting component 3 by pressing against the limiting blocks 31. Similarly, the limiting notch 32 can also be opened according to the size of the iron plates 83 on both sides of the relay coil 8.

[0041] After the relay coil 8 is produced by the previous process, the limiting component 3 with the relay coil 8 is transported by the transport device towards the placement component 2. The relay coil 8 is placed between the limiting blocks 31, and the iron plates 83 on both sides of the relay coil 8 extend into the limiting notches 32, so that the limiting blocks 31 hold the relay coil 8, so that the limiting component 3 restricts the relay coil 8 and prevents the relay coil 8 from shifting. When the transport device transports the limiting component 3 onto the placement base plate 20, the top pressing block 23 presses down on the top surface of the limiting block 31 to prevent the limiting component 3 from shifting inside the placement component 2. Then the drive device 1 is started. The rotating end of the drive device 1 rotates and drives the placement component 2 to flip through the mounting rod 10, so that the placement component 2 moves to one side of the vision lens 4 and turns the placement component 2 into an inverted state. At this time, because of the setting of the limiting component 3 and the placement component 2, the relay coil 8 will flip and invert as the placement component 2 is inverted. If the latching piece 82 does not accurately engage the armature 81, the armature 81, which is attached to the coil body, will move downwards and away from the coil body due to gravity, creating a gap between the coil body and the armature 81. If the visual lens 4 detects this gap, it can be determined that the latching piece 82 is not accurately engaging the armature 81, and a warning can be issued to the operator so that the operator can promptly identify the faulty relay coil 8. If the latching piece 82 accurately engages the armature 81, the armature 81 will not move downwards due to gravity because of the restriction of the latching piece 82. In this case, if the visual lens 4 detects that there is no gap between the coil body and the armature 81, it can be determined that the latching piece 82 is accurately engaging the armature 81. In this case, there is no need to warn the operator, and the relay coil 8 can continue to rotate. This achieves the purpose of detecting whether the latching piece 82 on the coil body is accurately engaging the armature 81, so that the operator can promptly identify the faulty relay coil 8.

[0042] It should be noted that the distance between the top pressing block 23 and the placement base plate 20 should be set to be exactly equal to the overall height of the limiting component 3, so that when the limiting component 3 is transported into the placement component 2 by the transport device, the top pressing block 23 will press down on the limiting component 3.

[0043] In other embodiments, the limiting component 3 of another structure includes a limiting base plate, two fixed plates, two limiting springs, and two limiting plates. The two fixed plates are fixedly disposed on the limiting base plate at a distance, and the two limiting springs are respectively fixedly disposed on opposite sides of the two fixed plates. The two limiting plates are respectively fixedly disposed on the two limiting springs and are disposed opposite to each other. The limiting springs are used to push the two limiting plates closer together. When the relay coil 8 needs to be placed on the limiting component 3, simply place the relay coil 8 directly above the position between the two limiting plates, and then press down on the relay coil 8. The pressed relay coil 8 pushes open the two limiting plates and moves between the two limiting plates. At this time, the limiting springs are compressed under pressure and exert a pushing force on the limiting plates, so that the two limiting plates clamp the relay coil 8, which can also lock the relay coil 8, thereby achieving the purpose of limiting the position of the relay.

[0044] Although the top pressure block 23 in the placement component 2 can restrict the limiting component 3, in actual use, the limiting component 3 needs to frequently pass through the placement component 2, with the top pressure block 23 contacting the limiting component 3 most frequently. This leads to severe wear at the end of the top pressure block 23 after a period of use, rendering it ineffective in pressing the limiting component 3. To solve this technical problem, this embodiment provides a pressing component 5 for pressing the top pressure block 23 on the side of the limiting top plate 22 facing away from the placement bottom plate 20. (Refer to...) Figure 4 The compression component 5 has two parts, each corresponding to one of the two top pressing blocks 23. The compression component 5 includes a connecting rod 50, an abutment block 51, and a compression spring 52. The connecting rod 50 is vertically fixed on the side of the limiting top plate 22 away from the placement bottom plate 20 and located on the side of the corresponding top pressing block 23. The abutment block 51 is fixed on the top of the connecting rod 50 and its bottom surface is opposite to the top surface of the top pressing block 23. The compression spring 52 is located between the abutment block 51 and the top pressing block 23. One end of the compression spring 52 is fixedly connected to the abutment block 51, and the other end of the compression spring 52 is used to push the top pressing block 23 to compress the limiting component 3. The top pressing block 23 is slidably inserted into the limiting top plate 22.

[0045] The connecting rod 50 can be installed on the limiting top plate 22 by welding, bonding, or other fixing methods. The abutment block 51 can be installed on the connecting rod 50 by welding, bonding, or other fixing methods. The compression spring 52 can be connected to one end of the abutment block 51 by welding, bonding, or other fixing methods. The end of the compression spring 52 that contacts the top pressure block 23 can be connected to or not connected to the top pressure block 23. That is to say, as long as the compression spring 52 can apply a pushing force to the top pressure block 23, the connection method between the compression spring 52 and the top pressure block 23 can be adjusted adaptively according to the actual situation.

[0046] By setting the compression component 5, when the limiting component 3 moves into the placement component 2 with the relay coil 8, the limiting block 31 in the limiting component 3 will squeeze the top pressure block 23, causing the top pressure block 23 to move upward and compress the compression spring 52 to contract. At the same time, the contracted compression spring 52 will also apply a pushing force to the top pressure block 23, so that the top pressure block 23 compresses the limiting block 31 and fixes the limiting component 3. When the end of the top pressure block 23 wears after the placement component 2 has been used for a period of time, the compression spring 52 can still push the top pressure block 23 to compress the limiting block 31, so that the worn top pressure block 23 can continue to exert a restrictive effect on the limiting component 3, thereby improving the service life of the top pressure block 23.

[0047] Although the compression component 5 improves the service life of the top pressure block 23, the relay coil 8 needs to be transported by a transport device in actual use. When the transport device carrying the relay coil 8 transports the limiting component 3 with the relay coil 8 to the placement component 2, the compression component 5 increases the friction between the limiting component 3 and the placement component 2. This causes the transport device carrying the relay coil 8 to output more power to transport the limiting component 3 with the relay coil 8 through the placement component 2. To solve this technical problem, this embodiment provides decompression components 6 on both sides of the limiting top plate 22 for the limiting top pressure block 23 to compress the limiting component 3. (Refer to...) Figure 2 and Figure 4 The decompression assembly 6 includes two portal frames 60, two decompression blocks 61, two contact rods 62, two decompression rods 63, two connecting rods 64, and two connecting shafts 65. The two portal frames 60 are located on both sides of the upright placement assembly 2. The two decompression blocks 61 are fixedly connected to both sides of the limiting top plate 22. The two contact rods 62 are connected to the two decompression rods 63 one-to-one to form two sets of decompression components. The two sets of decompression components are located on opposite sides of the two decompression blocks 61. The two connecting shafts 65 pass through the two sets of decompression components and the corresponding decompression blocks 61. The pressure relief component is rotatably connected to the pressure relief block 61. Two connecting rods 64 are respectively rotatably inserted through the ends of the two pressure relief rods 63 away from the contact rod 62, and one end is fixedly connected to the top pressure block 23. The pressure relief component has a restricted state and a released state. When the pressure relief component is in the restricted state, the pressure relief rod 63 pushes the connecting rod 64 upward, so that the top pressure block 23 moves upward and compresses the pressure spring 52. At this time, the contact rod 62 is vertically abutting against one side of the top of the portal frame 60. When the pressure relief component is in the released state, the pressure spring 52 releases the elastic force, so that the pressure relief rod 63 moves downward with the top pressure block 23.

[0048] Specifically, when the decompression component is in a restricted state, the contact rod 62 is in a vertically downward state and the side facing away from the decompression block 61 is attached to the gantry frame 60, while the decompression rod 63 is in an inclined state and gradually tilts upward from the end near the contact rod 62 to the direction away from the contact rod 62. The connecting rod 64 located at the end of the decompression rod 63 away from the contact rod 62 moves upward as the decompression rod 63 tilts upward, thereby pushing the connecting rod 64 upward so that the top pressure block 23 moves upward to compress the spring 52.

[0049] When the decompression component is in the released state, the contact rod 62 no longer adheres to the gantry frame 60. At this time, the pressure spring 52 releases its elastic force to push the top pressure block 23 downward. As the top pressure block 23 moves downward, the connecting rod 64 drives the end of the decompression rod 63 away from the contact rod 62 to move downward synchronously, so that the decompression rod 63 is in a horizontal state and the contact rod 62 is in an inclined state, thereby achieving the purpose of releasing the pressure spring 52 and causing the decompression rod 63 to move downward with the top pressure block 23.

[0050] By setting the decompression component 6, when installing the entire detection mechanism, the two gantry frames 60 need to be installed on the transport device with a gap between them and the two gantry frames 60 need to be located on both sides of the placement component 2 when the placement component 2 is in the upright position. This allows the transport device to transport the limit component 3 with the relay coil 8 to the placement component 2. When the placement component 2 is in the upright position, the decompression component contacts the gantry frame 60 and is in a restricted state. The decompression rod 63 in the decompression component pushes the connecting rod 64 to move upward, so that the top pressure block 23 moves upward to compress the compression spring 52. At this time, the compression spring 52 cannot push the top pressure block 23 to move, so the top pressure block 23 will not apply pressure to the limit component 3. Thus, the transport device does not need to output more power to transport the limit component 3 with the relay coil 8 through the placement component 2, saving the energy consumption of the transport device.

[0051] On the other hand, since the top pressure block 23 does not apply pressure to the limiting component 3, when the drive device 1 drives the placement component 2 to rotate and flip via the mounting rod 10, the limiting component 3 inside the placement component 2 loses the restriction of the top pressure block 23 and moves downward, causing the relay coil 8 on the limiting component 3 to fit against the limiting top plate 22 in the placement component 2. At this time, the vision lens 4 cannot accurately detect whether the armature 81 on the relay coil 8 is accurately installed. The setting of the decompression component 6 also solves this technical problem. When the drive device 1 drives the placement component 2 to rotate and flip via the mounting rod 10, the decompression component is separated from the portal frame 60. The decompression component, which is no longer restricted by the portal frame 60, is in a freed state. At this time, the compression spring 52 releases its elastic force, causing the decompression rod 63 to move downward with the top pressure block 23, so that the top pressure block 23 presses the limiting component 3 to prevent the limiting component 3 from shifting. This allows the vision lens 4 to accurately detect whether the armature 81 on the relay coil 8 is accurately installed.

[0052] It should be noted that when the relay coil 8 completes the detection and the drive device 1 drives the placement component 2 back to the upright position through the mounting rod 10, the inclined contact rod 62 contacts the gantry frame 60 during this process, and gradually moves to a vertical position as restricted by the gantry frame 60, so that the decompression component returns to the limit position again, allowing the limit component 3 to pass through the placement component 2.

[0053] In this embodiment, when the vision lens 4 monitors the inverted relay coil 8, the entire vision lens 4 needs to be placed horizontally so that the vision lens 4 can monitor the inverted relay coil 8. However, the horizontally placed vision lens 4 occupies a large amount of horizontal space, which is inconvenient for the installation of the vision lens 4. To solve this technical problem, this embodiment provides a support device 7 at the lower end of the vision lens 4. The support device 7 is used to support the vision lens 4. (Refer to...) Figure 2 and Figure 3 The support device 7 includes a support base 70, a support rod 71, a mounting block 72, a mounting seat 73, and a refractive prism 74. The support rod 71 is vertically fixed on the support base 70, the mounting block 72 is fixedly fixed on the top of the support rod 71, the vision lens 4 is vertically mounted on the mounting block 72 with the lens facing downwards, the mounting seat 73 is located directly below the vision lens 4 and is fixedly mounted on the support rod 71, and the refractive prism 74 is mounted on the mounting seat 73 and is used to refract the image of the inverted relay coil 8 for monitoring by the vision lens 4.

[0054] By setting up the support device 7, the visual lens 4 can be installed vertically, reducing the horizontal space occupied by the visual lens 4. At the same time, the inverted relay coil 8 image can be monitored through the refraction of the refracting prism 74, saving the installation space of the visual lens 4 without affecting the monitoring of the visual lens 4.

[0055] In this embodiment, a backlight plate 11 is provided on one side of the driving device 1 relative to the refractive prism 74. The backlight plate 11 is used to optimize the refractive background of the refractive prism 74 and prevent the complex environment of the factory from affecting the refractive effect of the refractive prism 74.

[0056] In this embodiment, a protective cover 75 surrounding the vision lens 4 is fixedly installed on the mounting block 72. The protective cover 75 has openings on its upper and lower sides for the vision lens 4 to monitor. The protective cover 75 covers the vision lens 4 to prevent other light from the factory from shining on the periphery of the vision lens 4, so as to prevent the complex environment of the factory from affecting the monitoring effect of the vision lens 4.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
