Description

Technical Field

[0001] This invention relates to the field of inverter manufacturing technology, specifically to an inverter housing transmission device. Background Technology

[0002] Photovoltaic inverters convert the variable direct current (DC) generated by photovoltaic (PV) solar panels into alternating current (AC) at grid frequency, which can be fed back into commercial power transmission systems or supplied to off-grid power grids. PV inverters are a crucial component for system balancing in PV array systems and can be used with general AC-powered equipment. Solar inverters also offer special functions tailored to PV arrays, such as maximum power point tracking and islanding protection.

[0003] A photovoltaic inverter consists of a boost circuit and an inverter bridge circuit. The boost circuit is mainly used to boost the DC voltage to the DC voltage required for the inverter output. The inverter bridge circuit is mainly used to convert the boosted DC voltage into AC voltage of a fixed frequency. The function of converting DC power into AC power is completed through the boost circuit and the inverter bridge circuit.

[0004] During the manufacturing process of inverters, conveyor equipment is used to transport the housing to various processing areas. When the housing is transported to the assembly area, the completed electronic components are assembled into the housing. After assembly, the housing is transported to the testing area for finished product testing of the housing and its internal electronic components, such as impulse withstand voltage, power frequency withstand voltage, leakage current, and partial discharge tests. After the impulse withstand voltage test, the housing needs to be checked for flatness and airtightness. Housings that fail the test need to be transported to the reprocessing area via conveyor equipment. The overall efficiency of this operation is relatively low, and the production cycle is difficult to control when the workload is large. To address this, we propose an inverter housing transport device. Summary of the Invention

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-10This invention provides a technical solution: an inverter housing transmission device. This invention addresses the technical problems mentioned in the background art by making corresponding improvements, including a transmission mechanism 1 for conveying the inverter housing. The transmission mechanism 1 consists of an inclined region 11 and a straight region 12. Further, the inclined region 11 is inclined upwards. A placement mechanism 2 for placing the inverter housing is installed on the transmission mechanism 1. As a further limitation of this invention, the placement mechanism 2 includes a support plate frame 21 fixedly installed on the transmission mechanism 1. This support plate frame 21 is used to place the inverter housing and simultaneously constrain the inverter housing to prevent displacement. A bracket 23 is also fixedly installed on the support plate frame 21. An air pipe 22 is installed on the support plate frame 21. A bracket 23 supports the air pipe 22. The air inlet of the air pipe 22 is located outside the support plate frame 21, and multiple air outlets 24 are installed on the air pipe 22. These air outlets 24 are located below the welded parts of the inverter housing. To further explain, during the manufacturing process, the inverter housing is connected to the main body by welding. During the pressure resistance test, if the housing deforms, cracks may easily appear at the welded parts. Limiting plates 3 are fixedly installed on both sides of the inclined area 11. Slots 5 are provided on the two limiting plates 3, and a load-bearing plate frame 4 is installed on the two limiting plates 3 for sliding connection with the inner wall of the slots 5. A fixed frame 99 is fixedly installed on the force plate frame 4. The fixed frame 99 also houses a testing mechanism 6 for performing a pressure resistance impact test on the inverter housing. As a further explanation of the invention, the testing mechanism 6 includes a cylinder and an impact hammer. When the inverter housing is transported on the inclined area 11 of the conveying mechanism 1, the impact hammer is directly above the inverter housing. It should be noted that the area of ​​the support plate frame 21 that defines the inverter housing is made of rubber. To improve the efficiency of the entire housing production process, the invention performs the corresponding test (pressure resistance impact test) on the conveying mechanism 1. Furthermore, the invention provides a drive mechanism 9 on the two limiting plates 3. This drive mechanism 9 utilizes the movement of the housing (transfer)... Mechanism 1 moves the housing in an directional manner through placement mechanism 2 to drive the force-bearing plate 4 to adjust its position on the limiting plate 3; at the same time, an air tightness detection mechanism 7 for air tightness detection of inverter housing is also provided below the fixed frame 81; so that under the action of drive mechanism 9, the force-bearing plate 4 moves at the same speed as inverter housing. During the movement, the testing mechanism 6 first performs a pressure resistance impact test on the housing. After the test is completed, the air pipe 22 is vented, and then under the action of air tightness detection mechanism 7, an air tightness test is performed on the housing after the impact test. A flatness detection mechanism 8 is also provided on the limiting plate 3. The flatness detection mechanism 8 is used to perform flatness detection on the housing after the impact test.

[0035] As a further limitation of the present invention, the drive mechanism 9 includes an inclined groove 91 disposed on two limiting plates 3. Further, the inclined groove 91 is inclined upwards on the limiting plates 3. Sliding rollers 93 are symmetrically disposed at the front end of the inverter housing. In the initial state, the sliding rollers 93 are located on the movement trajectory of the inverter housing, and the bottom of the sliding rollers 93 is close to the surface of the inclined region 11. A connecting post 92 for sliding connection with the inner wall of the inclined groove 91 is mounted on the sliding roller 93. The end of the connecting post 92 penetrates the inner wall of the inclined groove 91 and extends to the outside. A [missing information - likely a device or component] is installed at the outer end of the connecting post 92. Further, the sheet-like magnetic plate 94 is described as follows: the present invention has a force-applying plate frame 97 installed on the sliding roller 93, and a force-receiving frame 96 fixedly installed at the bottom of the force-receiving plate frame 4, with the force-applying plate frame 97 located inside the force-receiving frame 96. As a further limitation of the present invention, an electromagnet body 95 is fixedly installed on the outside of the two limiting plates 3, wherein the electromagnet body 95 generates a repulsive force on the sheet-like magnetic plate 94 when energized, and a control button 98 is fixedly installed at the end of the slot 5. The control button 98 is electrically connected to the electromagnet body 95. After the control button 98 is touched, the electromagnet body 95 generates a repulsive force after 3 seconds.

[0036] Specifically, when the inverter housing acts on the sliding roller 93, the sliding roller 93 is subjected to a force and moves synchronously with it. The connecting column 92 on it moves along the inclined groove 91. During the synchronous movement with the housing, the sliding roller 93 also adjusts its position longitudinally. At the same time, the force-applying plate 97 on the sliding roller 93 acts on the force-bearing frame 96. The force-bearing frame 96 is subjected to a force, causing the force-bearing plate 4 to move synchronously with the force-applying plate 97. This causes the force-bearing plate 4 and its fixed frame 99 to move. When the connecting column 92 moves to the end of the inclined groove 91, the sliding roller 93 is located above the housing. The housing continues to move and no longer pushes the sliding roller 93 to move. At the same time, it is subjected to a force. When the end of the plate frame 4 touches the control button 98 at the end of the slot 5, the control button 98 sends a signal to the electromagnet body 95. After 3 seconds, the electromagnet body 95 is energized and generates a repulsive force on the sheet magnetic plate 94 at the end of the connecting post 92. It should be noted that after 3 seconds, the housing passes the sliding roller 93, and the sliding roller 93 no longer contacts the housing. Under the repulsive action of gravity and the electromagnet body 95, the sliding roller 93 moves in the opposite direction (moving from the initial position) along the inclined slot 91 under the action of the connecting post 92. The electromagnet body 95 can be programmed to turn on after 3 seconds and turn off after 6 seconds after the control button 98 is touched. The specific settings can be made according to the actual use.

[0037] As a further limitation of the present invention, the airtightness testing mechanism 7 includes an annular sealing ring 71 disposed inside the fixed frame 99, and the annular sealing ring 71 is located above the welded part of the inverter housing. The bottom of the annular sealing ring 71 (i.e., the area in contact with the housing) is made of rubber. A plurality of fixed sleeves 72 are fixedly installed on the annular sealing ring 71, and an expansion airbag 73 is installed inside the fixed sleeve 72. The air inlet end of the expansion airbag 73 is located inside the annular sealing ring 71. A monitoring button 74 is fixedly installed on the inner wall of the top of the fixed sleeve 72. It should be noted that the monitoring button 74 is electrically connected to the terminal control. Furthermore, there is a certain distance between the monitoring button 74 and the inflatable airbag 73. After the inflatable airbag 73 expands, it can touch the monitoring button 74. As a further description of the present invention, a fixed seat 75 is symmetrically fixedly installed on the annular sealing ring 71, and a limiting post is installed on the fixed seat 75. The side walls of the fixed frame 99 and the force plate frame 4 are provided with annular grooves 77, and the side walls of the two limiting plates 3 are provided with adjustment grooves 78. As a further description of the present invention, the adjustment groove 78 is composed of a sliding area 781, a descending area 782 and a rising area 783. In the initial state, the end of the limiting post 76 is located on the sliding area 781.

[0038] Specifically, when the load-bearing plate 4 moves on the limiting plate 3, the testing mechanism 6 on the fixed frame 99 operates, that is, the cylinder drives the impact hammer to perform a pressure resistance impact test on the surface of the housing. Since the limiting column is located in the sliding area 781 in the initial state, the annular sealing ring 71 is located above the housing and does not contact its surface, thus avoiding damage to the annular sealing ring 71 caused by the impact force. When the limiting column moves to the descending area 782, the bottom of the annular sealing ring 71 contacts the housing. Since the bottom of the annular sealing ring 71 is made of rubber material, when the bottom of the annular sealing ring 71 is pressed tightly against the surface of the housing, a near-sealed environment is formed. At this time, the air pipe 2 2. Air intake: Gas flows out from outlet 24. If a crack appears in the shell, the gas will enter the annular sealing ring 71 through the crack. When gas enters the inflatable airbag 73, its shape expands and acts on monitoring button 74. Monitoring button 74 sends information to the terminal in the form of an electrical signal. After receiving the signal, the terminal controls the robot or other mechanical parts to remove the defective shell from the conveying mechanism 1. When the force plate 4 moves to near the end of the slot 5, the limiting column moves along the inner wall of the rising area 783, causing the annular sealing ring 71 to separate from the shell surface again, so as to avoid the annular sealing ring 71 from aging due to the force during subsequent shell transportation.

[0039] As a further limitation of the present invention, the flatness detection mechanism 8 includes a fixed frame 81 fixedly installed on the limiting plate 3, and a plurality of detection rollers 82 are provided below the fixed frame 81. A column 83 is installed on the detection rollers 82, and the end of the column 83 penetrates through the bottom inner wall of the fixed frame 81 and extends into its interior. A magnetic plate frame 84 is fixedly installed on the column 83. A plurality of electromagnet groups 85 are fixedly installed on the top inner wall of the fixed frame 81. When the electromagnet groups 85 are energized, they generate an attraction force on the magnetic plate frame 84. The electromagnet groups 85 are electrically connected to the control button 98. A touch post 86 is fixedly installed on the magnetic plate frame 84. A plurality of monitoring buttons 87 are fixedly installed on the bottom inner wall of the fixed frame 81. The monitoring buttons 87 are connected to the control terminal by an electrical signal. All monitoring buttons 87 are located below the touch post 86.

[0040] Specifically, as a specific embodiment of the present invention: In the initial state, the detection roller 82 is on the movement trajectory of the housing (i.e., in contact with the upper surface of the housing). When the force-bearing plate 4 moves to the end of the slot 5 and touches the control button 98, according to the program setting, after 2 seconds, the electromagnet group 85 is de-energized, and the electromagnet group 85 no longer attracts the magnetic plate 84. At this time, the detection roller 82 is still in contact with the upper surface of the housing (the same position as when the electromagnet group 85 is energized and attracts the magnetic plate 84). In this state, the touch post 86 is located at the monitoring button 8. The upper part of the housing does not contact the upper part. When a depression appears on the upper surface of the housing, the detection roller 82 descends under the action of gravity. At this time, the touch post 86 contacts and acts on the monitoring button 87. The monitoring button 87 sends the information to the terminal in the form of an electrical signal. In the invention, through program setting, the electromagnet group 85 is energized after 7 seconds. At this time, the detection roller 82 is exactly at the end of the upper surface of the housing (i.e., the detection surface detection is completed). Specifically, it can be set according to the actual situation. Thus, the present invention enables detection during transportation, thereby improving work efficiency.
