Description

Technical Field

[0001] The utility model relates to the technical field of production and detection of floor fans, in particular to a screw leakage prevention detection device and a floor fan production system. Background Art

[0002] The tube assembly of a floor fan is an important part of the floor fan, and usually includes an upper tube assembly and inner and outer column tubes and other structures. The upper tube assembly is one of the main components of the floor fan, and is usually fixedly connected to the fan rear shell. In an upper tube assembly of a floor fan, since the screw connection is located inside the tube, it is not easy to check the screws after assembly. In the prior art, there are usually two methods for checking the internal screws of the tube assembly: the first is to illuminate the inside of the tube assembly with a flashlight and manually observe whether the screws are missed; the second is that the inspector holds one end of the tube assembly with both hands and drags it to both sides with force. If the screws are not hit, the components of the tube assembly will separate, thereby achieving the purpose of detecting whether the screws are missed. The above two detection methods are both manually performed, with high labor intensity, which can easily cause worker fatigue, thereby affecting work efficiency and product quality, and cannot meet the needs of fast and efficient production. Moreover, the screw detection is carried out after the screws are tightened, and the detection process usually requires additional time, which increases the production cycle and increases the production cost of the floor fan.

[0003] Therefore, it is necessary to improve the existing screw detection method of the floor fan tube assembly to overcome the defects of the prior art. Utility Model Content

DETAILED DESCRIPTION

[0043] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0044] The tube assembly of a floor fan is an important part of the floor fan, and usually includes an upper tube assembly and inner and outer column tubes and other structures. The upper tube assembly is one of the main components of the floor fan, and is usually fixedly connected to the fan rear shell. In an upper tube assembly of a floor fan, since the screw connection is located inside the tube, it is not easy to check the screws after assembly. In the prior art, there are usually two methods for checking the internal screws of the tube assembly: the first is to illuminate the inside of the tube assembly with a flashlight and manually observe whether the screws are missed; the second is that the inspector holds one end of the tube assembly with both hands and drags it to both sides with force. If the screws are not hit, the components of the tube assembly will separate, thereby achieving the purpose of detecting whether the screws are missed. The above two detection methods are both manually performed, with high labor intensity, which can easily cause worker fatigue, thereby affecting work efficiency and product quality, and cannot meet the needs of fast and efficient production. Moreover, the screw detection is carried out after the screws are tightened, and the detection process usually requires additional time, which increases the production cycle and increases the production cost of the floor fan.

[0045] Based on this, the present application provides a screw missing prevention detection device.

[0046] Example 1

[0047] like Figure 1-Figure 7 As shown, this embodiment provides a screw leakage prevention detection device, which includes a box body 1, and a detection station is arranged in the box body 1;

[0048] The detection station includes a carrying mechanism and a detection mechanism, the carrying mechanism includes a movable carrying plate 2, a carrying position 21 is provided on the carrying plate 2, the detection mechanism is arranged below the carrying plate 2, and the detection mechanism includes a detection circuit;

[0049] When the tube assembly is screwed, the bearing plate 2 moves downward and presses the detection mechanism, so that the detection circuit is connected.

[0050] The device integrates a detection station in the box 1, and the device realizes real-time detection of screws while screwing the floor fan tube assembly, thereby greatly improving production efficiency. During use, when the tube assembly is screwing, it will be subjected to a downward force, and the force is transmitted downward to the bearing plate 2, causing the bearing plate 2 to move downward and squeeze the detection mechanism. The squeezing of the bearing plate 2 makes the detection circuit connected, that is, the screws of the floor fan tube assembly are detected. If the detection circuit cannot be connected during the processing of the floor fan tube assembly, it is determined that the corresponding floor fan tube assembly is missing a screw. This instant detection method reduces the waiting time and subsequent separate detection links in the production process, making the production line smoother and more efficient.

[0051] The detection device claimed in the present application can detect whether the floor fan duct group is screwed, and can also detect other household appliances or industrial products. The detection process is as follows: the workpiece to be screwed is placed on the bearing position 21 of the bearing plate 2, and then the product is screwed using a screw driver. Similarly, during the screwing process, pressure is applied to the bearing plate 2, causing the bearing plate 2 to move downward, and causing the bearing plate 2 to apply pressure to the detection mechanism, so that the detection circuit is connected.

[0052] It should be noted that the carrying plate 2 and the carrying position 21 of the present application can be improved as needed to achieve the detection of different products.

[0053] The detection device of the present application does not require additional manual operation during operation, which can reduce the labor intensity of screw detection of pipe assemblies and reduce the possibility of human error. This automated detection method not only improves the accuracy of detection, but also avoids missed detection or false detection caused by human factors.

[0054] In this embodiment, one implementation of the detection circuit is also provided. Specifically, the detection circuit includes a control switch 22, and the control switch 22 is arranged below the carrier plate 2;

[0055] When the tube assembly is screwed, the bearing plate 2 moves downward and presses the control switch 22, so that the detection circuit is connected.

[0056] Specifically, the control switch 22 is implemented by a limit switch. When the load-bearing plate 2 moves downward to squeeze the limit switch, the limit switch is pressed, so that the drop detection circuit can be connected, and the automatic detection of the screws of the pipe assembly can be realized. The limit switch is easy to install, and only two screws are needed to firmly fix the limit switch on the mechanical equipment, which simplifies the installation process. In addition, the limit switch has high round-trip accuracy and switching time accuracy, ensuring precise control. Moreover, the limit switch adopts a double-break contact design: the contact material is silver alloy, which has a circuit isolation function, further improving the safety performance of the product. In addition, the limit switch wiring is simple: the switch box cover is locked by a snap-fit ​​mechanism, and no screws are required to fix it, making the wiring operation simpler and faster.

[0057] In this embodiment, N inspection stations are provided in the box 1, where N is a natural number greater than 1. 4 to 6 inspection stations can be provided in the box 1, and multiple inspection stations can simultaneously inspect multiple different pipe assemblies during use, thereby improving production efficiency.

[0058] The detection device of the present application can detect multiple pipe assemblies at the same time by arranging multiple detection stations in the box body 1, thereby improving production efficiency.

[0059] Example 2

[0060] like Figure 1-Figure 7 As shown, in this embodiment, a specific structure of a box 1 is provided. The box 1 of the present application is not only the main body of the detection device, providing an installation position for various devices, but also can cooperate with a screw driver to detect the screws of the pipe assembly while driving the screws.

[0061] In order to ensure the structural strength of the box body 1 , the box body 1 may be made of high-strength plastic, and reinforcing ribs may be avoided in the box body 1 to improve the structural strength of the box body 1 .

[0062] Specifically, a partition 13 is provided in the box body 1, a first installation cavity 11 is formed between the partition 13 and the top wall of the box body 1, a second installation cavity 12 is formed between the partition 13 and the bottom wall of the box body 1, the supporting plate 2 is provided on the partition 13, an elastic device 23 is provided between the supporting plate 2 and the partition 13, the control switch 22 is provided on the partition 13 and is located below the supporting plate 2; the first installation cavity 11 is located above the second installation cavity 12.

[0063] The elastic device 23 of the present application can be a spring. When the supporting plate 2 moves downward, the spring is squeezed to compress the spring, thereby applying pressure to the control switch 22 to turn on the detection circuit. In addition, the elastic device 23 of the present application can be provided with multiple springs at the bottom of the supporting plate 2 to support the supporting plate 2.

[0064] The detection circuit further includes a relay 5 and an indicator light 15 . The relay 5 is disposed in the second installation cavity 12 , and the indicator light 15 is disposed on the outer wall of the box body 1 . The relay 5 is electrically connected to the control switch 22 and the indicator light 15 , respectively.

[0065] The partition 13 separates different parts of the box 1. By installing the carrier board 2 and the detection circuit in different chambers, the devices in different chambers do not interfere with each other, thereby ensuring the operational stability of the entire device. In addition, the partition 13 is used to separate the box 1 into a first installation chamber 11 and a second installation chamber 12, which effectively distinguishes different functional areas, realizes efficient use of space, and facilitates the installation and maintenance of equipment.

[0066] The working process of the detection device of the present application is described below:

[0067] Before using this device, the detection circuit must first be connected to an external power supply so that the detection circuit is in a powered-on state to be detected. Then, the inspector places the floor fan tube assembly without screws on the placement position on the support plate 2. After the floor fan tube assembly is placed stably, the screwing operation can be performed. When screwing the tube assembly, the tube assembly will be subjected to a downward pressure, and the pressure is transmitted to the elastic device 23 through the support plate 2. After the elastic device 23 is compressed, the support plate 2 will move downward until the control switch 22 is pressed, and the relay 5 corresponding to the control switch 22 is energized, and the relay 5 continues to remain in a closed energized state, so the indicator light 15 corresponding to the relay 5 can remain normally lit. As the screwing is completed, the pressure applied to the tube assembly disappears, and the elastic device 23 will return to its initial state.

[0068] Since the detection device of the present application is provided with multiple detection stations, the structure of each station can be the same, and can include a carrier board 2 and a detection circuit. For example, 4 detection stations are provided, and during the detection process, 4 pipe assemblies are detected at the same time. When all the screws of the 4 pipe assemblies are screwed, the indicator lights 15 corresponding to each detection station are turned on. If all the indicator lights 15 are on, it means that all the screws have been screwed. If the indicator lights 154 are not on, it means that the corresponding pipe assembly has missed screwing.

[0069] Example 3

[0070] like Figure 1-Figure 7 As shown, in this embodiment, the embodiment 2 is improved. Specifically:

[0071] The box body 1 is further provided with a limiting hole 14 , which is arranged above the carrying plate 2 , and the limiting hole 14 corresponds to the carrying position 21 .

[0072] The limiting hole 14 is arranged on the top wall of the box body 1. Specifically, the cross section of the limiting hole 14 can be circular, rectangular or other shapes. The cross section of the limiting hole 14 needs to correspond to the shape of the pipe assembly to be detected so as to limit the pipe assembly.

[0073] The limiting hole 14 cooperates with the bearing position 21 of the bearing plate 2. Specifically, the bearing position 21 limits the tube assembly from the bottom, and the limiting hole 14 limits the tube assembly from the top, ensuring that the tube assembly can be accurately placed in the predetermined position, thereby improving the positioning accuracy during the production process.

[0074] Example 4

[0075] like Figure 1-Figure 7 As shown, in this embodiment, an improvement is made on the basis of Embodiment 3.

[0076] Specifically, a first limiting sleeve 24 is disposed in the bearing position 21, and the first limiting sleeve 24 is engaged with the bearing position 21;

[0077] The limiting hole 14 is provided with a second limiting sleeve 16 , which includes a first sleeve body 161 and a second sleeve body 162 . The first sleeve body 161 and the second sleeve body 162 are respectively provided on two opposite sides of the limiting hole 14 , and the first sleeve body 161 and the second sleeve body 162 are threadedly connected.

[0078] The first limiting sleeve 24 is used to change the size of the bearing position 21 , and the second limiting sleeve 16 is used to change the size of the limiting hole 14 .

[0079] In this embodiment, by introducing the first limiting sleeve 24 and the second limiting sleeve 16, the bearing position 21 and the limiting hole 14 can be flexibly adjusted in size, so as to match pipe assemblies of different sizes and shapes. This improvement significantly enhances the applicability of the detection device, so that the detection device can be widely used in the detection of pipe assemblies of various specifications.

[0080] The design of the first limiting sleeve 24 and the second limiting sleeve 16 enables the operator to quickly adjust the size of the bearing position 21 and the limiting hole 14 according to actual conditions without replacing the entire bearing plate 2 or the box body 1, thereby greatly improving the convenience of operation.

[0081] Due to the adjustability of the bearing position 21 and the limiting hole 14, the enterprise does not need to prepare a variety of detection devices for pipe assemblies of different specifications, thereby reducing inventory costs and equipment replacement costs.

[0082] In addition, the improvement in adaptability means that different specifications of pipe components can be switched for testing more quickly during the production process, reducing production downtime caused by equipment replacement or adjustment, thereby improving production efficiency.

[0083] Example 5

[0084] like Figure 1-Figure 7 As shown, in this embodiment, the detection device of the present application is improved on the basis of Embodiment 2. The details are as follows:

[0085] A controller 6 is also provided in the box body 1, and the controller 6 is electrically connected to the detection circuit; a buzzer 4 is also provided on the box body 1, and the buzzer 4 is electrically connected to the controller 6; a reset button 3 is provided on the top of the box body 1, and the reset button 3 is electrically connected to the controller 6.

[0086] The controller 6 is used to control the operation of the entire device. After the detection is completed, the buzzer 4 emits a buzzer sound to prompt that the assembly of the tube assembly and the screw is completed. The reset button 3 is used to reset the entire detection device after the detection is completed.

[0087] The controller 6 of the present application may be a microcontroller 6 or a PLC controller 6. The controller 6 can accurately manage the detection process and ensure the accurate execution of each link, thereby improving the automation and controllability of the detection process.

[0088] The design of the reset button 3 of the present application enables the detection device to be quickly reset after completing one detection, so as to prepare for the next detection. This fast reset function greatly improves the continuous operation capability of the equipment and reduces the downtime in the production process.

[0089] Example 5

[0090] like Figure 1-Figure 7As shown, this embodiment is an improvement on Embodiment 1. In this Embodiment 1, the detection circuit includes a pressure switch, and the pressure switch is arranged below the bearing plate 2.

[0091] In another embodiment, the detection circuit is turned on and off by a pressure switch. When the pressure applied to the pressure switch by the support plate 2 exceeds a set threshold, the detection circuit can be turned on, thereby realizing the detection of the tube assembly.

[0092] This embodiment uses a pressure switch as the trigger mechanism of the detection circuit, which can reduce the complexity of manual operation. The operator only needs to place the tube assembly on the carrier plate 2, and the detection process can be automatically triggered without additional operation, thereby improving the convenience and automation of operation. The pressure switch, as a mechanical sensing element, has a simple and durable structure and has higher reliability than other complex sensors. This reduces the failure rate of the equipment and reduces maintenance costs.

[0093] And by adjusting the threshold of the pressure switch, it can adapt to pipe assemblies of different weights or specifications, so that the detection device has certain flexibility and scalability.

[0094] Example 6

[0095] like Figure 1-Figure 7 As shown, in this embodiment, a guide rod 25 is provided in the box body 1, a guide hole is provided on the bearing plate 2, and the guide rod 25 passes through the guide hole in a vertical direction.

[0096] The guide rod 25 can guide the carrying plate 2 on the carrying plate 2 so that the carrying plate 2 runs smoothly, thereby ensuring accurate detection.

[0097] By providing a guide rod 25 in the box body 1 and correspondingly providing a guide hole on the bearing plate 2, the bearing plate 2 can run smoothly along the guide rod 25 during the up and down movement. This design significantly improves the smoothness of the movement of the bearing plate 2 and reduces the shaking or deviation that may occur during the movement, thereby ensuring the stability and accuracy of the detection process. Due to the smooth operation of the bearing plate 2, the pipe assembly can maintain a relatively stable position during the detection process, which helps to reduce the detection error caused by the unstable movement of the bearing plate 2. Therefore, the design of this embodiment helps to improve the accuracy and reliability of the detection.

[0098] It should be noted that there is a clearance fit between the guide rod 25 and the guide hole.

[0099] Example 7

[0100] like Figure 1-Figure 7As shown, the second purpose of the utility model is to provide a floor fan production system, which includes a screw driving machine and the screw missing prevention detection device as described above, wherein the screw driving machine is arranged on one side of the screw missing prevention detection device, and the screw driving machine includes a screw driving mechanism, and the screw driving mechanism is located above the detection station.

[0101] Specifically, the screw driving machine of the present application can adopt an existing screw driving machine, and a feeding device is provided on one side of the leak detection device for conveying the pipe assembly to the detection station of the leak detection device. Then the screw driving machine tightens the screws on the pipe assembly, and the leak detection device performs detection during the screwing process.

[0102] The system enables automatic detection of screws of tube assemblies, thus helping to ensure production quality of floor fans.

[0103] The production system integrates the screw leakage detection device and the screw driving machine into one system, realizing efficient integration of the production process. This layout can shorten the time of material handling and equipment conversion, thereby improving the overall production efficiency.

[0104] Operators can complete the two steps of screw driving and inspection continuously at the same workstation without moving between different equipment, thereby simplifying the operation process and reducing work intensity.

[0105] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0106] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components.
