Description

Technical Field

[0001] This invention relates to the field of NTC welding and testing, and more specifically, to an NTC welding and testing apparatus. Background Technology

[0002] With the rapid development of economy and technology, the application of NTC thermistors is very standardized. With the advent of Industry 4.0 and the era of big data, the application fields of NTC thermistors are becoming wider and wider. Some fan motors need to install NTCs. NTCs are installed on fan motors by soldering. In the production process, after the NTC is soldered onto the semi-finished fan motor, it is necessary to test whether the NTC is soldered properly to prevent defective products from affecting subsequent production.

[0003] Existing welding equipment and equipment for testing NTCs on semi-finished motors are mostly two independent devices, not integrated into one. Manual operation is required to complete the welding and testing of NTCs on semi-finished motors using two different devices. Some semi-finished motors with similar specifications have similar structures, differing only in the location of the NTC. These two types of semi-finished motors are often produced on the same production line. Furthermore, the equipment for testing NTCs on semi-finished motors is mostly semi-automated, resulting in many processes such as testing NTCs at different locations on semi-finished motors and loading and unloading requiring manual operation. This leads to low efficiency and high costs. Summary of the Invention

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be given below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are some embodiments of the present invention, but 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 protection scope of the present invention. In addition, the directional terms mentioned in the present invention, such as "up," "down," "front," "back," "left," "right," "inner," and "outer," are only for reference to the directions in the accompanying illustrations. The use of directional terms is for better and clearer explanation and understanding of the present invention, and is not intended to indicate or imply any necessary orientation of the present invention, and therefore should not be construed as a limitation of the present invention.

[0031] Examples of embodiments of the present invention Figures 1 to 8 As shown, an NTC welding and testing device includes a base 1. A conveying mechanism 10 for transporting semi-finished motors with NTC components is mounted on the base 1. The conveying mechanism 10 is a chain conveyor, with a left-right conveying direction. The chain conveyor is located at the rear of the top surface of the base 1. A welding mechanism 2 is mounted on the base 1, located in front of the chain conveyor on the top surface of the base 1 and on the left side of the base 1. A first loading / unloading mechanism 3 is mounted on the base 1 for loading / unloading the semi-finished motors from the conveying mechanism 10 and the welding mechanism 2. The first loading / unloading mechanism 3 is located at... The base 1 is positioned between the conveying mechanism 10 and the welding mechanism 2 on its top surface. The base 1 is also equipped with a testing mechanism 4 for testing the resistance of the welded NTC on the semi-finished motor. The testing mechanism 4 is located in front of the chain conveyor on the top surface of the base 1 and to the right of the welding mechanism 2. The testing mechanism 4 is equipped with a driving mechanism to drive the testing mechanism 4 to test NTC at different positions. The base 1 is equipped with a second loading and unloading mechanism 7 for loading and unloading the semi-finished motor on the conveying mechanism 10 and the testing mechanism 4. The second loading and unloading mechanism 7 is a two-axis robot, which is located to the right of the testing mechanism 4.

[0032] This equipment integrates the welding mechanism 2 and the testing mechanism 4 together. Under the action of the conveying mechanism 10, the first loading and unloading mechanism 3 and the second loading and unloading mechanism 7, after the equipment is set and debugged, it automatically performs welding and testing of NTC on the semi-finished motor. No manual operation is required, which improves production efficiency and reduces labor costs. At the same time, when the testing mechanism 4 tests two semi-finished motors of similar specifications, the driving mechanism drives the testing mechanism 4 to move, thereby testing the NTC on the two semi-finished motors.

[0033] Further improvements, such as Figures 4 to 8As shown, the testing mechanism 4 includes a support frame 40 for supporting semi-finished motors, a test head 42, a two-axis moving platform 43, a mounting plate 44, and a power supply mechanism for providing power to the NTC. The support frame 40 is mounted on the base 1. Two semi-finished motors of different specifications are spaced apart on the support frame 40 in a front-to-back direction, with the NTC located at different positions on the two semi-finished motors. The two semi-finished motors of different specifications are the first semi-finished motor and the second semi-finished motor. The power supply mechanism is mounted on the base 1, and the two-axis moving platform 43 is also mounted on the base 1. The horizontal movement direction of the two-axis moving platform 43 is the front-to-back direction. The mounting plate 44 is mounted on the two-axis moving platform 43. A vertical extension plate is provided at the rear end of the mounting plate 44, and the mounting plate 44 is connected to the two-axis moving platform 43 via the extension plate. A rotating component 46 is rotatably mounted on the top surface of the mounting plate 44. The rotating component 46 has a cuboid structure, and a first support frame 47 is provided on the side of the rotating component 46 near the support frame 40, i.e., the first support frame 47 is located at the front end of the rotating component 46. The test head 42 is mounted on the first support frame 47. The test head 42 is a cylindrical temperature tester. The test head 42 tests the NTC by detecting the temperature of the NTC after it is powered on. The axis of the test head 42 is parallel to the horizontal... The included angle of the direction is 60°. The mounting plate 44 is provided with a clearance through hole 440 to avoid the test head 42. The clearance through hole 440 is located near the front end of the mounting plate 44. The test head 42 passes through the clearance through hole 440 and exits the bottom surface of the mounting plate 44. The drive mechanism is set on the mounting plate 44. The drive mechanism drives the rotating part 46 to rotate. The base 1 is provided with a defective product rack 45 located on the moving path of the two-axis moving platform 43. The defective product rack 45 is located directly in front of the support frame 40 on the top surface of the base 1. The second loading and unloading mechanism 7 loads two semi-finished product motors of different specifications from the conveying mechanism 10 onto the support frame 40. The mechanism supplies power to the NTCs on the two semi-finished motors. The two-axis moving platform 43 moves the mounting plate 44 down, allowing the test head 42 to test the first semi-finished motor. After the test, the two-axis moving platform 43 moves the mounting plate 44 above the second semi-finished motor. The two-axis moving platform 43 moves the mounting plate 44 down again. At this time, the drive mechanism rotating part 46 rotates, allowing the test head 42 to turn to the position of the NTC on the second semi-finished motor. Then the test head 42 tests the NTC. At the same time, the unqualified semi-finished motors tested by the second loading and unloading mechanism 7 are unloaded onto the defective product rack 45, while qualified semi-finished motors are unloaded onto the conveying mechanism 10.

[0034] Further improvements, such as Figures 6 to 8As shown, the driving mechanism includes an electric cylinder 6, a connecting rod 60, a first electrode 61, and a second electrode 62. The electric cylinder 6 is disposed on the top surface of the mounting plate 44, located at the right rear side. One end of the connecting rod 60 is hinged to the output shaft of the electric cylinder 6, and the other end is hinged to the rotating component 46. The connecting rod 60 is hinged to the right rear side of the top surface of the rotating component 46. The first electrode 61 is disposed at the bottom end of the mounting plate 44 and is electrically connected to the electric cylinder 6. The second electrode 62 is disposed on the top of the support frame 40, located directly below the first electrode 61, and is electrically connected to an external power source. A first mounting block 63 is disposed at the bottom end of the mounting plate 44, located at the right rear side of the bottom surface of the mounting plate 44. The top of the support frame 40 is provided with... A second mounting block 64 is positioned directly below the first mounting block 63, located to the right rear of the second semi-finished motor. The first electrode 61 is embedded on the bottom surface of the first mounting block 63, and the second electrode 62 is embedded on the top surface of the second mounting block 64. The first electrode 61 is a spring needle, and the second electrode 62 is a copper sheet. When testing the second semi-finished motor, the two-axis moving platform 43 moves the mounting plate 44 downward, causing the spring needle and the copper sheet to contact each other, thereby energizing the electric cylinder 6. The electric cylinder 6 rotates the rotating part 46 via the connecting rod 60, thereby turning the test head 42 to the NTC position on the second semi-finished motor. When the mounting plate 44 moves upward, the spring needle and the copper sheet no longer contact each other, and the electric cylinder 6 returns to its original position, driving the rotating part 46 to return to its original position via the connecting rod 60, thereby returning the test head 42 to its original position for testing the next first semi-finished motor.

[0035] Further improvements, such as Figure 5 and Figure 6As shown, the power supply mechanism includes a vertical electric linear slide 5, a power supply column 50, and a connecting frame 51. The electric linear slide 5 is mounted on the base 1, and the connecting frame 51 is mounted on the electric linear slide 5. The support frame 40 has an n-shaped structure and includes a horizontal part and two supporting parts supporting the horizontal part. The supporting parts are located on the left and right sides of the bottom end of the horizontal part and are mounted on the base 1. The horizontal part has two horizontal grooves for limiting and placing semi-finished motors. The first semi-finished motor and the second semi-finished motor are correspondingly placed in the two horizontal grooves. The horizontal part has two horizontal grooves for limiting and placing semi-finished motors. The bottom of each slot is provided with a horizontal through hole 41 that exposes the position of the semi-finished motor to be tested. The pins on the semi-finished motor that are electrically connected to the NTC are exposed through the horizontal through hole 41. A power supply post 50 is provided directly below each horizontal through hole 41, that is, a power supply post 50 is provided directly below each pin that is electrically connected to the NTC. The power supply post 50 is electrically connected to an external power source. The power supply post 50 is set on the connecting frame 51. The electric linear slide 5 drives the power supply post 50 to rise through the connecting frame 51, so that the power supply post 50 contacts the pin, thereby allowing the NTC to receive power and start working, so that the test head can test the NTC.

[0036] Further improvements, such as Figure 7 and Figure 8 As shown, a rotating through hole is provided at the middle position of the top surface of the rotating component 46 near the first support frame 47, that is, the rotating through hole is located on the top surface of the rotating component 46 near the middle of the front end. A rotating shaft 8 is provided on the mounting plate 44 to match and insert into the rotating through hole. An arc-shaped limiting through hole 460 with the rotating shaft 8 as the center is also provided on the top surface of the rotating component 46. The limiting through hole 460 is located on the side of the rotating component 46 away from the first support frame 47, that is, the limiting through hole 460 is located on the top surface of the rotating component 46 near the middle of the rear end. A limiting post 9 is provided on the mounting plate 44 to insert into the limiting through hole 460. The rotating component 46 is rotatably mounted on the mounting plate 44 through the rotating through hole and the rotating shaft 8. The limiting through hole 460 and the limiting post 9 prevent the rotating component 46 from rotating too far, which would cause the test head 42 to fail to align with the NTC on the second semi-finished product motor.

[0037] Further improvements, such as Figure 1 and Figure 3 As shown, the welding mechanism 2 includes a three-axis moving platform 20 and a welding head 21. The three-axis moving platform 20 is mounted on the base 1, and the welding head 21 is mounted on the three-axis moving platform 20. After the first loading and unloading mechanism 3 loads the semi-finished motor onto the three-axis moving platform 20, the three-axis moving platform 20 drives the welding head 21 to weld the NTC on the semi-finished motor. That is, the welding mechanism 2 automatically welds the NTC on the semi-finished motor.

[0038] Further improvements, such as Figure 1 and Figure 2 As shown, the first loading and unloading mechanism 3 includes a rotary cylinder 30, a rotating plate 31, and two cylinder grippers 32. The rotary cylinder 30 is located between the conveying mechanism 10 and the welding mechanism 2. The base 1 is provided with a lifting support frame 33 for lifting the rotary cylinder 30. The lifting support frame 33 includes a lifting plate and two electric telescopic rods. The two electric telescopic rods are located on the left and right sides of the bottom surface of the lifting plate, respectively. The electric telescopic rods are located on the top surface of the base 1. The rotary cylinder 30 is located on the top surface of the lifting plate, with the output end of the rotary cylinder 30 facing upwards. The center position of the rotating plate 31 is connected to the output end of the rotary cylinder 30. The two cylinder grippers 32 are located at opposite ends of the rotating plate 31. Through the rotary cylinder 30, the lifting support frame 33, and the cylinder grippers 32, the semi-finished motor to be welded on the conveying mechanism 10 is loaded onto the welding mechanism 2, and the welded semi-finished motor on the welding mechanism 2 is unloaded onto the conveying mechanism 10.

[0039] An NTC soldering and testing method, the method comprising the following steps:

[0040] S101, the conveying mechanism 10 conveys the semi-finished motor loaded with NTC from the previous station, and the first loading and unloading mechanism 3 loads the semi-finished motor onto the welding mechanism 2.

[0041] S102, welding mechanism 2 welds the NTC on the semi-finished motor firmly, and first loading and unloading mechanism 3 unloads the semi-finished motor onto conveying mechanism 10;

[0042] S103, the conveying mechanism 10 continues to convey the welded semi-finished motor, and the second loading and unloading mechanism 7 loads the semi-finished motor onto the testing mechanism 4.

[0043] S104, the testing mechanism 4 tests the NTC welded on the semi-finished motor, the drive mechanism drives the testing mechanism 4 to test the NTC at different positions, and the second loading and unloading mechanism 7 unloads the qualified semi-finished motor after testing to the conveying mechanism 10.

[0044] S105, the conveyor mechanism 10 transports the qualified semi-finished motors after testing to the subsequent workstations.
