Description

Technical Field

[0001] The utility model relates to the technical field of fool-proof tooling, in particular to a fool-proof tooling for fan installation. Background Art

[0002] Poka-yoke is a preventative and corrective behavioral restraint method. It utilizes restrictive methods to prevent errors, allowing operators to directly and accurately complete correct operations without requiring attention, experience, or expertise. In industrial design, to prevent user errors from causing harm to the machine or personnel (including unconscious actions, subconscious misoperations, and careless body movements), preventative measures are implemented to address these potential situations. These are called poka-yoke.

[0003] As a heat dissipation component, fans require critical installation. However, incorrect orientation of the fan's wiring terminals during installation can easily lead to subsequent connection problems and even equipment failure. Traditional inspection methods rely on workers' visual acuity and experience, which is not only time-consuming but also prone to errors. Therefore, a fool-proof tool for fan installation has been proposed. Utility Model Content

[0004] The purpose of the present invention is to provide a fool-proof tool for fan installation to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a fan installation fool-proof tool, comprising a support plate, a baffle fixed to one side of the top of the support plate, two limiting grooves formed on one side of the baffle, and two second sliding grooves formed on one side of the support plate;

[0006] The top of the support plate is respectively provided with a first scale line and a second scale line located on one side of the second chute;

[0007] A fan body is slidably connected to the inner side of the second sliding groove, and a connection terminal is connected to one side of the fan body;

[0008] A lifting assembly is provided on the lower side of the support plate;

[0009] The lifting assembly includes a transverse plate, and two fixing brackets are fixed to the top of the transverse plate and the bottom of the support plate. A first sliding groove is opened on one side of the fixing bracket, and a sliding column is slidably connected to the inner side of the first sliding groove.

[0010] Preferably, when the connecting terminal is inserted into the inner side of the limiting groove, one side of the fan body is located on the side of the first scale line; when the connecting terminal is not inserted into the inner side of the limiting groove, one side of the fan body is located on the side of the second scale line.

[0011] Preferably, two first hinged arms are hinged on one side of the top of the transverse plate, and a second hinged arm is rotatably connected to one side of the sliding column via a bearing.

[0012] Preferably, the middle parts of the first articulated arm and the second articulated arm are hinged to each other, the top end of the second articulated arm is hinged to the bottom side of the support plate, and the top end of the first articulated arm is rotatably connected to one side of the sliding column through a bearing.

[0013] Preferably, a motor is fixed to one side of the horizontal plate, and a screw is fixed to the output shaft end of the motor.

[0014] Preferably, a slide plate is rotatably connected between the two slide posts at the bottom via a bearing, the outer side of the screw rod is threadedly connected to one side of the slide plate, and two fixing blocks are fixed to one side of the top of the transverse plate.

[0015] Preferably, a slide bar is fixed between the fixed blocks, the outer side of the slide bar movably passes through one side of the skateboard, a battery is installed at the bottom of the transverse plate, and the battery output shaft is electrically connected to the input end of the motor.

[0016] Compared with the prior art, the above technical solution adopted by the present invention has the following technical effects:

[0017] First, by sliding the fan body inside the second slot and pushing the terminal toward the baffle, you can quickly determine whether the terminal is installed in the correct direction. When the terminal is correctly inserted into the limit slot, one side of the fan body will be on the side of the first scale mark, indicating that the terminal is installed in the correct direction. Conversely, if the terminal cannot be inserted into the limit slot, one side of the fan body will be on the side of the second scale mark, indicating that the terminal is installed in the wrong direction. Determining installation direction based on changes in physical position reduces the error rate of manual judgment, shortens inspection time, and improves work efficiency.

[0018] Second, workers can adjust the motor according to their height by simply pressing a switch, causing the screw to threadably connect to the slide. The first and second articulated arms then adjust the height of the support plate, allowing workers to perform inspections in the most comfortable posture. This reduces fatigue and strain caused by maintaining an uncomfortable posture for extended periods. The convenient adjustment of the support plate height allows workers of different heights to fully utilize the equipment for inspections. This helps improve equipment utilization and overall production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Example

[0030] See also Figure 1-6 When the fan body 2 is in the state of being rotated, the fan body 2 is rotated in the direction of rotation, and the rotation of the fan body 2 is reversed.

[0031] When the terminal 9 is inserted into the limiting slot 7 , one side of the fan body 2 is located on the side of the first scale line 3 ; when the terminal 9 is not inserted into the limiting slot 7 , one side of the fan body 2 is located on the side of the second scale line 4 .

[0032] A lifting assembly 5 is provided on the lower side of the support plate 1;

[0033] In order to facilitate different workers to use tooling to inspect the fan body 2, a lifting assembly 5 is provided. The lifting assembly 5 includes a horizontal plate 51. Two fixing frames 58 are fixed on the top of the horizontal plate 51 and the bottom of the support plate 1. A first slide groove 59 is provided on one side of the fixing frame 58. A slide column 57 is slidably connected to the inner side of the first slide groove 59. Two first hinged arms 55 are hinged on one side of the top of the horizontal plate 51. A second hinged arm 56 is rotatably connected to one side of the slide column 57 through a bearing. The slide plate 512 moves along the slide rod 511. When the slide plate 512 moves toward the side of the motor 54, the slide column 57 slides inside the first slide groove 59.

[0034] The first articulated arm 55 and the second articulated arm 56 are hinged to each other in the middle, and the top end of the second articulated arm 56 is hinged to the bottom side of the support plate 1. The top end of the first articulated arm 55 is rotatably connected to one side of the sliding column 57 through a bearing. A motor 54 is fixed to one side of the cross plate 51, and a screw rod 53 is fixed to the output shaft end of the motor 54.

[0035] When the slider 512 is moved away from the motor 54, the top and bottom ends of the first hinge arm 55 and the second hinge arm 56 are moved closer to each other, so that the height of the support plate 1 is increased.

[0036] Working principle: When checking the direction of the terminal 9 of the fan body 2, it is only necessary to slide the fan body 2 inside the second slide groove 6, and then push the terminal 9 on one side of the fan body 2 to move toward the side of the baffle 8. When the terminal 9 is inserted into the inner side of the limit groove 7, one side of the fan body 2 is located on the side of the first scale line 3. At this time, it can be determined that the terminal 9 on the side of the fan body 2 is not installed upside down;

[0037] When the terminal block 9 is installed upside down, the terminal block 9 cannot be inserted into the inner side of the limiting groove 7. At this time, one side of the fan body 2 is located on the side of the second scale line 4. At this time, the worker can visually check that the one side of the fan body 2 is aligned with the second scale line 4 and determine that the terminal block 9 on the side of the fan body 2 is installed in the wrong direction.

[0038] When different workers are checking the terminal blocks 9 of the fan body 2, since different workers have different heights, in order to facilitate the workers to check the terminal blocks 9 in the most comfortable posture, they only need to press the switch to control the motor 54 to start working. The output shaft of the motor 54 drives the screw rod 53 to rotate. At this time, the screw rod 53 is threadedly connected to the slide plate 512, so that the slide plate 512 moves along the slide rod 511. When the slide plate 512 moves toward the side of the motor 54, the slide column 57 slides inside the first slide groove 59, and at the same time, the top and bottom ends of the first articulated arm 55 and the second articulated arm 56 move away from each other, so that the height of the support plate 1 decreases. When the slide plate 512 moves away from the motor 54, the top and bottom ends of the first articulated arm 55 and the second articulated arm 56 approach each other, so that the height of the support plate 1 increases. At this time, the height of the support plate 1 can be easily adjusted.

[0039] In summary, by sliding the fan body 2 inside the second slide groove 6 and pushing the terminal block 9 toward the baffle 8, it is possible to quickly determine whether the installation direction of the terminal block 9 is correct. When the terminal block 9 is correctly inserted into the limit groove 7, one side of the fan body 2 will be located on the side of the first scale line 3, indicating that the installation direction of the terminal block 9 is correct. On the contrary, if the terminal block 9 cannot be inserted into the limit groove 7, one side of the fan body 2 will be located on the side of the second scale line 4. At this time, the installation direction of the terminal block 9 is incorrect. Determining the installation direction by the change in physical position reduces the error rate of human judgment, reduces inspection time, and improves work efficiency.

[0040] Workers can adjust the height of the support plate 1 by simply pressing a switch to operate the motor 54 according to their height, threading the screw rod 53 into the slide plate 512. The first articulated arm 55 and the second articulated arm 56 then adjust the height of the support plate 1, allowing workers to perform inspections in the most comfortable posture, reducing fatigue and strain caused by maintaining an uncomfortable posture for extended periods. The convenient adjustment of the support plate 1 height allows workers of different heights to fully utilize the equipment for inspections. This helps improve equipment utilization and overall production efficiency.

[0041] The model of the motor 54 is ASF102A. The output shaft end of the motor 54 has a brake structure. Since the internal structure and operating principle of the motor 54 of this model are both existing technologies, they will not be described in detail here.
