[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.
[0021] The existing inverter solder joint detection device is inconvenient to adjust the position of the detection module unit when in use. Moreover, due to the complexity of the solder joint situation, the detection module unit with a fixed angle cannot perform high-quality detection of solder joints at different positions, resulting in poor performance and causing inconvenience to the staff.
[0022] In view of this, the present invention provides an automatic welding joint detection device for inverters. Through the cooperation of a base plate, a vision detection module, a vertical plate, an adjustment device, and a regulating device, the angle and position of the vision detection module can be adjusted, thereby enabling all-round detection of the inverter's welding joints. This improves the quality of the detection, ensures the accuracy of the detection data, and reduces the workload of workers because no manual adjustment is required.
[0023] Example 1: By Figure 1 , 2 As shown in 4 and 5, an automatic welding joint detection device for inverters includes a base plate 1, a vertical plate 5 fixedly connected to one side of the top of the base plate 1, a controller 6 fixedly connected to the side of the base plate 1 near the top of the vertical plate 5, a vision detection module 7 electrically connected to the controller 6, an adjustment device 3 disposed above the base plate 1, and an adjustment device 2 disposed above one side of the vertical plate 5. The adjustment device 2 includes: a first electric push rod 21, fixedly connected to the upper side of one side of the outer wall of the base plate 1 and electrically connected to the controller 6; and a crossbar 2. 2. Two vertical plates 23 are fixedly connected to the upper part of one side of the outer wall of the vertical plate 5; the top plate 23 is attached to the outer wall of the two horizontal bars 22; two limiting strips 24 are fixedly connected to the inner wall of the top plate 23 and are slidably engaged with the inner wall of the two horizontal bars 22 respectively; the servo motor 25 is fixedly connected to the top of the top plate 23 and electrically connected to the controller 6; wherein, the first electric push rod 21 drives the top plate 23 to move along the outer wall of the horizontal bar 22, and the limiting strips 24 limit the horizontal bar 22 and the top plate 23.
[0024] In the specific implementation process, it is worth noting that the models of controller 6, first electric actuator 21, servo motor 25, and vision inspection module 7 are not limited, as long as they meet the usage requirements. It should be noted that the maximum rotation angle of servo motor 25 is 360 degrees, which avoids the phenomenon of wire tangling due to multiple rotations. Furthermore, when electrically connecting servo motor 25, vision inspection module 7, and second electric actuator 32, a certain amount of wire slack should be reserved to avoid wire pulling during position adjustments. The specific length of the reserved wire slack is not limited and can be determined according to actual needs. The application is determined by the user, and since this is a relatively common and well-known technology, it will not be elaborated on in this case. Those skilled in the art should understand it in a broad sense. The servo motor 25 drives the visual inspection module 7 to change the angle, thereby driving the visual inspection module 7 to rotate so as to inspect the solder joints at different positions of the inverter. The first electric push rod 21 can change the position of the top plate 23 on the outer wall of the crossbar 22, thereby changing the position of the visual inspection module 7. The visual inspection module 7 can detect the welding status of the solder joints and then send the detection signal to the controller 6, which then performs data analysis and processing.
[0025] Furthermore, the adjustment device 3 includes: a support plate 31, fixedly connected to the output end of the servo motor 25, and rotatably connected to the inner wall of the top plate 23 via a bearing on its outer wall; a second electric push rod 32, fixedly connected to the bottom of the support plate 31, and electrically connected to the controller 6; a base 33, fixedly connected to the output end of the second electric push rod 32; a slide plate 34, rotatably connected to the outer wall of the base 33 via a pin; a slide rail 35, slidably engaged with the inner wall of the slide plate 34; and a mounting plate 36, fixedly connected to the outer wall of the slide rail 35, and rotatably connected to the bottom of the support plate 31 via a pin. The second electric push rod 32, through the base 33, changes the sliding of the slide plate 34 along the outer wall of the slide rail 35, changes the angle of the mounting plate 36, and thus adjusts the detection angle of the vision detection module 7.
[0026] In the specific implementation process, it is worth noting that a stop is provided on the top of the support plate 31. The design of the stop can prevent the output end of the servo motor 25 and the bearing from being directly subjected to force, thereby preventing the servo motor 25 and the bearing from being damaged by force. The model of the second electric push rod 32 is not limited, as long as it meets the usage requirements. The second electric push rod 32 can use the base 33 to change the position of the slide plate 34 on the outer wall of the slide rail 35, thereby adjusting the angle of the mounting plate 36 in order to adjust the detection angle of the vision inspection module 7.
[0027] Specifically, when using this inverter automatic welding joint detection device, when the position of the vision detection module 7 needs to be adjusted, the first electric push rod 21 is activated. The first electric push rod 21 drives the top plate 23 to move, and the top plate 23 can then drive the limit strip 24 to move along the inner wall of the crossbar 22. At this time, the position of the vision detection module 7 can be changed. Then, the second electric push rod 32 is activated. The second electric push rod 32 drives the slide plate 34 to move along the outer wall of the slide rail 35 through the base 33. At this time, the angle of the mounting plate 36 can be adjusted, thereby adjusting the detection angle of the vision detection module 7. Then, the servo motor 25 is activated. The servo motor 25 drives the support plate 31 to rotate, which in turn drives the vision detection module 7 to rotate, thereby enabling all-round detection of the inverter welding joints. After rotating one revolution, it rotates another revolution, and then performs a second detection to ensure the accuracy of the detection data. Then, the vision detection module 7 sends the detection signal to the controller 6, which then analyzes and processes it to complete the detection work.
[0028] Example 2: From Figure 1 and 3It is known that a cleaning device 4 is provided on the top side of the base plate 1 near the vertical plate 5. The cleaning device 4 includes: a box 41, which is fixedly connected to the top side of the base plate 1 near the vertical plate 5; a partition 42, which is fixedly connected to the inner wall of the box 41; a fan 43, which is fixedly connected to the top of the partition 42, and whose output end penetrates through the inner wall of one side of the box 41; and a hose 44, which is connected to the output end of the fan 43. The fan 43 delivers air to the inside of the hose 44, and the worker holds the hose 44 to clean the workpiece.
[0029] In the specific implementation process, it is worth noting that there is no restriction on the model of the fan 43, as long as it meets the usage requirements. The fan 43 can deliver air into the inside of the hose 44, and then the staff can hold the hose 44 to clean the solder joints of the inverter in order to avoid dust accumulation affecting the accuracy of the test data.
[0030] Furthermore, a filter screen 421 is fixedly connected to the inner wall of the partition 42;
[0031] In the specific implementation process, it is worth noting that the mesh size of filter 421 is not limited, as long as it meets the usage requirements. Filter 421 can block and collect dust in the air. It should be noted that the staff should regularly clean the dust inside the box 41 and the filter 421. When cleaning the filter 421, it can be disassembled for cleaning. There are no restrictions on the specific cleaning method and cleaning cycle, as long as the usage requirements are met.
[0032] Specifically, based on the above embodiment one, before testing, the staff turns on the fan 43, which delivers the air filtered by the filter screen 421 to the inside of the hose 44. Then the staff can hold the hose 44 to clean the solder joints of the inverter.
[0033] Example 3: From Figure 1 It can be seen that a rubber pad 9 is fixedly connected to the top of the base plate 1, and two baffles 8 are fixedly connected to the top of the base plate 1.
[0034] In the specific implementation process, it is worth noting that the rubber pad 9 can increase the contact friction between the inverter and the base plate 1 to ensure the stability during placement, and the baffle 8 can restrict the position of the inverter so that the inverter is always within a certain range, thereby assisting the vision inspection module 7 to perform better inspection work.
[0035] Specifically, based on the above embodiment one, when using it, the operator places the inverter on top of the rubber pad 9 between the two baffles 8. Then, the operator can adjust it according to the interval between the inverter and the two baffles 8. Since the visual inspection module 7 has an automatic focusing function, there is no need to accurately position the inverter. It only needs to be in a general position. After placement, the inspection work can be carried out.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
